1.—On the Halticide of the Canary Islands. By T. Vernon 
Wortaston, M.A., F.L.S. 


In the following paper I propose to enumerate such members of the 
Halticide, amounting in all to eighteen well-defined species, which 
have been hitherto observed in the Canarian archipelago. Their 
detection is due to the combined researches of John Gray, Esq., and 
myself, in January and February of 1858 (whilst visiting the various 
islands in his yacht, the ‘‘ Miranda,” in which he afterwards sailed 
for the West Indies); and to those, subsequently, of myself alone 
during the five following months of the same year, as also during 
February, March, April and May of 1859. And since, therefore, the 
whole seven islands have been explored (indeed four of them twice 
over, and some very carefully), it is believed that the subjoined list 
will give a fair approximate idea of the entire Halticideous fauna of 
that sub-African Group. I have been mainly induced to undertake 
it through the instigation of my friend M. Allard, of Paris, who is 
preparing a Monograph of the European and North-African forms, 
and in which therefore the species of these Atlantic islands should 
be properly inserted.

The present interesting little Haltica is closely allied, in affinity 
and general facies, to the European H. atrope, of which I possess 
specimens communicated to me by M. Allard. It is, however, a trifle 
smaller than that insect, and its head and prothorax are pale rufo- 
testaceous, instead of black ; its limbs also are paler, its punctuation 
(although coarse) not quite so rugose, and the dark portions of its 
elytra are very much narrower and less developed. I captured it 
abundantly throughout the whole district immediately above the 
Puerto de la Orotava, in the north of Teneriffe, during February and 
March of 1858,—where it was entirely confined to the Physalis 
aristata (a plant intimately allied to the Atropa Belladonna, being of 
the same natural family, and, as I am informed by the Rey. R. T. 
Lowe, possessing nearly the same chemical properties), on the leaves 
of which shrub it subsists. I have much pleasure in dedicating it 
to M. Allard, to whose kindness I am indebted for an accurate com- 


parison of my Canarian Halticide with his large collection of Euro- 
pean and North-African types.

A metallic species of very variable colour, shading off from bright 
eyaneous-blue into golden-green, and almost, at times, into coppery- 
brown. It is attached to the foliage of the various large EKuphorbias, 
and was taken on the H. Regis Jube by Mr. Gray and myself on the 
cliffs above the Salinas, in the north of Lanzarote, during January 
1858 (in which same locality I captured it again, abundantly, in 
March of the following year); as also, by myself, on the mountains 
above San Martao, in Grand Canary; on the E. piscatoria above the 
Puerto de la Orotaya, of Teneriffe ; and in the district of El Golfo, 
in the west of Hierro. -I have dedicated it to my learned and excel- 
lent friend the Bardo do Castello de Paiva, to whose researches, 
especially in Madeira and Portugal, I have been frequently indebted 
for many additions to my collection. 


3. Haltica crassipes, n. sp. 


H, cylindrico-ovata nitida subhyalina testacea, capite paulo rufescentiore, 
prothorace transverso-subquadrato angulis ipsis posticis leviter promi- 
nulis acutiusculis, elytris paulo pallidioribus leviter subtilissime punc- 
tulatis, antennarum articulis 4 basalibus rufo-testaceis, reliquis paulatim

At first sight the present insect and the following one are some- 
what alike; nevertheless, apart from the generic characters (of the 
longer legs and hind feet, &c.) of Longitarsus, the H. crassipes may 
be known by its more quadrate prothorax, stouter antennee (which 
have four of their basal joints, instead of only three, more or less 
testaceous), and by its more finely punctured elytra. Its four ante- 
rior male tarsi have their basal joint greatly dilated, so as far to 
exceed the second,—a structure which is more or less expressed in 
most of the Halticide, but which in the H. crassipes is peculiarly 
conspicuous. I am informed by M. Allard, of Paris, that it is un-

questionably new, though slightly akin to his Aphthona flaviceps,— 
which, however, is smaller, with its prothorax and antenne shorter, 
and the feet of its males less expanded, &e. It is apparently rare ; 
nevertheless I have taken it sparingly at the Agua Mansa, in Tene- 
riffe ; and from off plants (I think chiefly Semperviva) growing on 
the damp rocks in the deep sylvan ravines of Palma,—especially the 
Barranco da Agua, towards the north-east of the island.

4. Longitarsus Kleiniiperda, n. sp. 


L. oblongo-ovatus subnitidus pallido-testaceus, capite vix rufescentiore, 
prothorace antice angustiore angulis posticis obtusis, elytris sat profunde

minus subito nigris, pedibus fere concoloribus (femoribus posticis vix

Habitat in plantis Kleinie neriifolie, DC., gregatim, folia destruens, in ins. 
Teneriffa, Palma ét Hierro. 


The prima facie distinctions (apart from generic ones) between 
the present insect and the last one have been already pointed out. 
It is much allied, at first sight, to the common L. tabidus of more 
northern latitudes ; nevertheless it is less convex and more strongly 
punctured than that species, its prothorax is less abbreviated and 
rather more narrowed in front, its antenne and legs are longer, and 
the basal joint of the four front male feet is altogether larger, and 
broader. Its habits, too, are quite different, since it appears to be 
almost entirely attached to the leaves of the Kleinia neriifolia, on 
which it often exists by thousands, and whole plants of which I have 
occasionally observed almost defoliated by its attacks. In such posi- 
tions I have taken it abundantly in the waste grounds above the 
Puerto of Orotava, and near Santa Cruz, as also in the sylvan 
districts of the Agua Garcia and Taganana, of Teneriffe ; in the 
Barranco above Santa Cruz, of Palma; and towards the coast, in 
El Golfo, of Hierro. 


5. Longitarsus persimilis, n. sp. 


L. oblongo-ovatus angustulus subnitidus lete maculatus; capite nigro- 
piceo, fronte rufescentiore ; prothorace rufo-testaceo sublunulato (an-

rotundata centrali) in singulo positis ornatis ; antennis basi rufo-testa- 
ceis, apicem versus nigrescentibus ; pedibus testaceis, femoribus posticis 
apice nigris.

Mas, tarsorum anteriorum articulo basilari sat dilatato. 

Habitat in foliis Echiorum (preesertim £. s’mplicis) in locis editioribus 
Teneriffe et Hierro. 


Before examining critically this beautiful Longitarsus, I had re- 
garded it as a mere topographical state of the Madeiran LZ. Masoni 
(the L. Isoplexidis, Ins. Mad. 443, tab. 9. f. 4); for, being attached 
principally to a gigantic Echium closely related to the E. candicans 
on which that insect subsists, being exposed, apparently, to much the 
same external conditions as its ally, and ornamented with almost 
the same colouring, I did not imagine it probable that the small 
prima facie differences which it presented would be anything more 
than such as we might reasonably look for, as the result of local 
influences, in the same species inhabiting islands so separated from 
each other as Madeira and Teneriffe. Nevertheless, on a nearer 
inspection, the LZ. persimilis possesses such a number of minor cha- 
racters peculiarly its own, that I cannot feel justified, despite the 
many points of resemblance in the two insects, in regarding them as 
otherwise than truly distinct, though clearly members of the same 
geographical province. The Canarian species may be readily known 
from the Madeiran one by its uniformly smaller size, rather shorter 
and more lunulate prothorax (which is a little more truncated in 
front, and has the hinder angles more rounded-off, and the sides 
somewhat more angulated in the middle), and by its entire sculpture, 
which is denser and very much more coarse, especially on the elytra 
(which are also more evidently striated than is the case in the 
L. Masoni). Its elytra also are slightly more truncated at their 
apex, its whole surface much less opake, and its coloration is alto- 
gether a little different,—its head being less black, or more piceous, 
its prothorax more evidently rufo-testaceous, its legs and elytra not 
quite so pale, and the dark portions of the latter smaller in size; 
z.e. the humeral and discal patches are, both of them, reduced in 
dimensions, and the sutural line is equal throughout, being scarcely 
(if at all) expanded posteriorly, whereas in the L. Masoni it is regu- 
larly hastate or spear-shaped. Its limbs, moreover, are shorter and 
less robust. It seems almost confined to the foliage of a large

Echiwm (which the Rey. R. T. Lowe informs me is probably the 
E. simplex), much resembling, in general growth and aspect, the 
Madeiran EZ. candicans, on which I have taken it abundantly at the 
foot of the Organo rocks in the sylvan region above the Agua Mansa, 
of Teneriffe, nearly 5000 feet above the sea. It does occasionally, 
however, occur on other and smaller plants of the same genus, on 
one of which (I believe the Z. violacewm) I captured it, during 
February of 1849, on the hills to the west of Valverde, in the island 
of Hierro. 
6. Longitarsus Messerschmidtice, n. sp. 
L, precedenti valde affinis, sed vix minor et gracilior, sculptura subtiliore 
et colore paulo pallidiore elytris fere vel omnino immaculatis. 
Long. corp. lin. 1—vix 1}. 
Variat (varior) elytris plaga parva centrali in singulo posita (necnon

Habitat in foliis Messerschmidtie fruticose in ins. Teneriffa ét Hierro, hinc 
inde vulgaris. 

It is not without some little hesitation that I regard the present 
Longitarsus as distinct from the preceding one; nevertheless, since 
its normal facies is very dissimilar, and its habits different, I think 
it is scarcely safe to amalgamate the two. Indeed, in its general 
aspect it is so unlike the Z. persimilis, that no one could ever suppose 
them to be identical, did not an occasional (though very rare) variety 
of the present insect make such a curious approach, in the arrange- 
ment of its colouring, to its ally, as to lead one to suspect that it may 
be but a phasis of the latter, gradually assumed through the adoption 
of a totally different plant for its subsistence. Still this is but con- 
jecture, and I therefore prefer treating the two as separate. In its 
typical state, the LZ. Messerschmidtie is, on the average, a trifle 
smaller and narrower than its ally, its sculpture is less deep, and it 
is of a uniformly pale, brownish-testaceous hue. Its elytra, how- 
ever (in which case the apex of its posterior femora are also dark), 
have an occasional tendency to become clouded about their disk, 
suture, and shoulders ; and in one or two highly coloured specimens 
(out of many hundreds which I possess) the discal cloud assumes 
the form of a small well-defined patch (and even the humeral one is 
somewhat concentrated),—thus causing them to resemble very much 
the paler examples of the L. persimilis. Such individuals, however, 
are extremely scarce ; and even in them the lighter sculpture pre- 
vails (as in the ordinary ones); and therefore, in spite of their prima 
facie approach to the last species, I must regard their connectiveness 
as more apparent than real. So far as I have hitherto observed, the 


Mr. T. V. Wollaston on the Halticidee of the Canary Islands. 7 


present Longitarsus is exclusively attached to the fragrant Messer- 
schmidtia fruticosa,—on which shrub, when carefully examined, I 
have scarcely ever failed to detect it. Its range is consequently 
somewhat lower than that of the L. persimilis, which feeds on the 
Echia of more lofty elevations. IJ have taken it abundantly in the 
waste grounds above the Puerto of Orotava, as well as between Ycod 
de los Vinhos and Garachico, of Teneriffe; on rocks between the 
plains of los Llanos and the Pinal, in the Banda, of Palma; and a 
little above the sea-coast, in the district of El Golfo, to the west of 
Hierro.

Habitat in insulis Canaria et Teneriffa, rarior. 


The common European ZL. ochroleucus appears to be somewhat 
scarce, or at any rate extremely local, in the Canaries, and may 
perhaps have been introduced into the islands. I have taken it 
sparingly near Santa Cruz in Teneriffe; and, more abundantly, in 
Grand Canary, where, during April 1858, it was rather plentiful on 
the mountain-slopes above San Martao, on the ascent to the Roca 
del Soucilho.

The single specimen, from which I have drawn out the above 
description, was detected by John Gray, Esq., near Port Cabras, in 
the island of Fuerteventura, during our sojourn there, in his yacht, 
at the end of January 1858. It is a good deal allied, at first sight, 
to the common European ZL. tabidus, but is smaller and of a more 
pallid hue, and with its hind femora dark. Its antenne also are 
slenderer ; its prothorax shorter, more truncated in front, and less 
margined at the edges ; and its punctuation is altogether very much 
finer.

Like the last species, the present one has been also described from 
a unique example. It was captured, by myself, from off a plant of 
the Heliophytum erosum, Lemann, on the sands behind the sea-beach 
to the south of Arrecife, in the island of Lanzarote, during April 
1859. There were three more specimens in company with it, but I 
unfortunately failed in securing them. It is apparently akin to the 
L. atricapillus, Dufts., of more northern latitudes; and M. Allard, of 
Paris, to whom I lately submitted it for inspection, returned it with 
the observation: “ affinis Teinodactyle atricapille, Dufts., sed aliter 
colorata, capite et prothorace latioribus, antennis brevioribus, et cet.”

A single specimen of the Madeiran L. nubigena was captured by 
John Gray, Esq., near San Sebastian, in Gomera, during our visit to 
that island at the beginning of February 1858. It is a trifle larger 
than any of the few examples which I have hitherto taken in 
Madeira ; but in all other particulars (such as colour, outline, sculp- 
ture, &ec.) it agrees with them precisely.

places around Haria (especially, I think, from off the Mercurialis 
annua, L.), during January of 1858; and I subsequently captured 
it in the same locality during March of the following year. But it 
is the only region in which I have hitherto observed it throughout 
the Canarian group.

The single specimen described above was captured by myself, at 
the beginning of May 1859, in Teneriffe, on the mountain-slopes 
midway between the Agua Mansa and the Cumbre, more than 5000 
feet above the sea. It very much resembles the European L. thora- 
cicus, Steph., of which it may perhaps be but a geographical state ; 
nevertheless, since M. Allard, to whom I lately transmitted it for 
inspection, believes it to be distinct therefrom, I have treated it 
accordingly. It seems to differ principally from that species in its 
smaller size and larger punctuation.

The L. fusco-eneus was first detected in the Canary Islands by 
Mr. Gray, who took three specimens of it near Puerto de Cabras 
in Fuerteventura; and it was subsequently captured by myself in 
Teneriffe,—both on the mountains above S* Cruz and at the Agua 
Garcia. It occurs principally on the leaves of the Echiwm violaceum, 
L., and, for the most part, in company with the Z. Echit.

Sebastian in Gomera, and near S* Cruz in Palma. It is identical 
with the species which I described, from the Madeiran Group, in 
1857, under the name of Z. excurvus, from specimens detected in 
Porto Santa by Mr. Bewicke.

The P. hospes abounds at low and intermediate elevations through- 
out the Canarian Group, on the whole seven islands of which I have 
taken it in greater or less profusion; and it was also captured in 
Lanzarote, Gomera, and Hierro by Mr. Gray. In the Madeiras also, 
though less common, it is nearly (if not quite) universal, having been 
observed by myself in Madeira proper, in Porto Santo, and on the 
Dezerta Grande ; so that it may be properly regarded as an Atlantic 
species. It is the representative of the P. cwprea of more northern 
latitudes; and M. Allard, to whose examination I have lately sub- 
mitted it, returned it with the remark: “ Psyll. cupree, IU, affinis, 
et ut illa in elytris punctato-striata, sed differt interstitiis punctu-

Like the last species, the present one abounds throughout the 
Canarian archipelago, Gomera being the only island on which I have 
not hitherto captured it ; nevertheless there can be no doubt that it 
exists there, no less than on the others,—our short visit to that 
island happening to be during the depth of winter, when the Halti- 
cide are not plentiful. It was taken also by Mr. Gray in Fuerte- 
ventura and Palma. It is equally common likewise in the neigh- 
bouring group, where I have observed it, in profusion, at nearly all 
elevations in Madeira proper, as well as in Porto Santo and on the 
Dezerta Grande.

The small, convex, seneo-piceous Psylliodes described above, the

its shallow punctures) minutely alutaceous, is tolerably abundant in 
certain parts of Lanzarote and Fuerteventura,—in the former of 
which islands it was taken both by Mr. Gray and myself, on the 
common Mercurialis annua, in the vicinity of Haria, during January 
1858; and in the latter, by myself, at Oliva, towards the end of 
March of the following year.

The general aspect of the present Chetocnema is almost the same 
as that of the common European C. aridella, except that it is a little 
more «neous and shining, that the prothorax is somewhat more 
truncated (or less produced behind), and that the intermediate joints 
of the antenne are rather slenderer ; and it was not until closely over- 
hauling it that I detected a structwral character which at once sepa- 
rated it from its more northern ally. This consists in the formation 
of the tarsi, which are very much narrower and more elongated than 
those of the C. aridella, with their apical joint especially (as com- 
pared with the corresponding one in that species) long and slender. 
The penultimate one also is less dilated than is the case in that 
insect, and the whole foot has a different appearance. It was detected 
by myself, on the 14th of April, 1858, at Argeniguin, in the south

II.—Remarks on the Pollinosity of the Genera Lixus and Larinus. 
By Henri Jexet, Member of the Entomological Society of France, 
&e. &e. 


Tue following paper, the manuscript of which was delivered to Mr. 
White, of the British Museum, in January 1859, together with cer- 
tain remarks on two species of Larinus, for Mr. Daniel Hanbury, to 
accompany his note on the products of these two species*, has not 
(from a misunderstanding on my part?) been added to that note, but 
was returned to me a few weeks ago by Mr. White. I had under- 
stood Mr. Hanbury desired me, besides determining the two species, 
to give a general account of the authors who had treated on the 
habits of that genus; hence the few remarks which I now beg for 
acceptance in this Journal, hoping they will not be devoid of interest. 

With respect to the tomentosity and pollinose transudation of Liwus 
and Larinus, I think it will not be out of place to mention here a 
fact until now overlooked, so far as I know. It appears to me, from 
long observation of the covering adorning many Curculionideous 
Beetles, that Nature acts, in clothing them, by layers or coatings. 
There is, immediately above the derm of the elytra and thorax, a 
thin tomentose squamosity, either more or less piliform and opake, 
or very fine, silky, and bright. This ground-layer, common to many 
other tomentose Coleoptera, is comparatively persistent, though far 
more easily rubbed off than setiform or hairy pilosity, and is analogous 
to the squamosity of species having one layer only. This tomentosity 
is not produced by exudation, but grows according to the general 
law, is susceptible of partial or total baldness, as in merely squamose 
insects, and if rubbed off, when the insect is alive, would be restored 
in course of time only, Then comes the second layer, much less 
persistent (even in non-pollinose speciest), which in the above two 
genera, as in many others, is a real pollinose transudation, suscep- 
tible of a relatively immediate renewal when rubbed off the living 
insect. Of this upper layer I need not remark, after the con- 
scientious observations of M. Godart, the highly interesting contro-

iii. p. 178 (1859).

versies of MM. Coquerel and Laboulbéne, and the experience of M. 
Rojas*, all recorded in the ‘ Annales de la Société Entomologique de 
France,’ 1851-1857. 

Hence the results in pollinose species are these: specimens may 
have their pollinosity more or less rubbed off, and show underneath 
part of the ground squamose tomentosity ; others may be completely 
deprived of that pollinose efflorescence, and show the ground tomen- 
tosity only ; finally, others, still more rubbed, show only a portion of 
the latter, &c. Any entomologist, therefore, in describing either 
squamose, tomentose, or pollinose species, should not content him- 
self with the description of so variable a substance only, but note 
also if there is another layer beneath it, and, in fine, should lay 
bare the derm in order to display its characters. 

Exclusive of hair or pile, to which (like naked Coleoptera) squamose, 
tomentose, or pollinose species are liable, one might divide them, 
according to the composition of their clothing, as follows :— 

1. Col. Monolepida: haying a single layer of squamosity or tomen- 
tosity, with or without denser markings. 


* One of M. Rojas’s observations bears on a species of Lixus, inhabiting Vene- 
zuela, that I called L. vittatus in litt., intending to describe it in its proper place in 
‘Insecta Saundersiana.’ I think it now preferable to profit by this opportunity to 
give a complete diagnosis of the species, and change its name, Ist, in honour of 
that zealous entomologist ; 2ndly, because, as that gentleman observes, very fresh 
specimens are so densely covered with sulphureo-ochraceous pollinose dust, 
and others, entirely rubbed off, are so completely destitute of it, that the w¢te 
are hardly discernible.

2. Col. Dilepida: having two layers of squamosity or tomentosity, 
one inferior, with or without denser markings, generally of a 
pale unicolor hue (grey, ashy, or whitish); the other supe- 
rior, less persistent, easier rubbed off, increasing or modifying ~ 
the coloration of the markings, when they exist, and filling 
more or less the areas between the markings. 

3. Col. Paipalepida: ground-layer tomentose, following the same 
laws as in class 2; but superior layer being a pollinose trans- 
udation, more or less deeply colouring the ground, as well as 
the ground-markings, when they exist. 

To complete the various modes in which the derm of 
Coleoptera presents itself to the eye of the entomologist, the 
naked species (always exclusive of hair or pile) should form 
the fourth class (or rather the first of all), viz..— 

4. Col. Alepida. 

As a supplement to the above observations, it will not be super- 
fluous, I hope, to give a summary list of the principal species of 
Larinus, whose habitat, food, even larva state and metamorphoses, 
have been recorded by various authors; a stimulus, I think, to 
further researches on the part of such entomologists as may be in 
the condition of making so desirable investigations.

I1.—Characters of undescribed Species of the Genus Leucospis. 
By F, Water, F.L.S. 


Tur Leucospide are very distinct from the other families of Chalci- 
dites, and appear to be nearly as much allied to the Cynipites, and 
to connect the two tribes. 

In New Caledonia they are represented by Z. antiqua ; in the Aru 
Islands by Z. Aruera and Aruina ; in China by Z. Sinensis ; in Hin- 
dostan by Z. atra, petiolata, and Guzeratensis ; in South Africa by 
L. ornata and incarnata; in West Africa by Marres dicomas; in 
North Africa by ZL. brevicauda, Fabricit, and Algirica ; in Egypt by 
L. miniata, frenata, scutellata, obsoleta, and intermedia ; in Arabia by 
L. elegans ; in Tauria by L. aculeata and gibba ; in South Europe by 
L. grandis, gigas, nigricorns, intermedia, Spinole, varia, Biguetina, 
dorsigera, rufonotata, clavata, Grohmann, assimilis, and Sicelis ; in 
Canada by ZL. Canadensis ; in the United States by L. Shuckardi, 
subnotata, and basalis; in Mexico by LZ. Klug and Mexicana ; in 
the West Indies by &. Cayennensis; in South America by L. Hoper, 
Cayennensis, leucotelus, Santarema, Egaia, Tapayosa, and sperfera, 
and by Polistomorpha Surinamensis and sphegoides. 

It thus appears that the Mediterranean region is their chief habi- 
tation, and there they have their most characteristic form, which is 
more or less modified in several other districts. 

In North America and in China there is no alteration of the 


of the Genus Leucospis. 17 


typical structure ; in Hindostan the species, as represented by L. 
atra, hardly differ from the Mediterranean type, except in colour, 
and the same may be said of Z. ornata in South Africa. In West 
Africa the only one known species is very peculiar, and in Aru 
Island the species differ less from those of Europe than in New 
Caledonia; but the greatest variation occurs in Mexico, in the West 
Indies, and in South America, and the principal group in the latter 
continent may be divided into at least four subgroups. One of these 
has been named Metallopsis, but is hardly sufficiently different from 
Leucospis. Polistomorpha forms a very distinct genus. 


Lerucospis Aneirica. Fwm. Nigra, sat angusta, scapo subtus, protho- 
racis margine interrupto scutellique fascia flavis ; abdomen fasciis 
quatuor flavis, 1* lata, 2° angusta, 3° arcuata, 4* apicali; pedes flavi, 
femoribus anterioribus nigris apice flavis, femoribus posticis nigris 
flavo late marginatis. 

Female. Black, rather narrow. Antenne with the scape yellow 
beneath. Prothorax with a yellow- margin, which is interrupted on 
each side of the fore border. Scutellum with a broad yellow band. 
Epimera of the metathorax yellow. Abdomen sessile, subfusiform, with 
four yellow bands; first band broad ; second narrow, much interrupted ; 
third arched; fourth apical, vertical. Oviduct reflexed to the base of 
the abdomen. Legs yellow; anterior femora black, with yellow tips ; 
hind femora black, broadly bordered above with yellow. Wings cine- 
reous, brownish along the costa and at the tips. Length of the body 
41 lines; of the wings 7 lines.

tarsis pallide rufescentibus, alis luridis. 

Male. Black, thickly punctured, with pale pubescence. Scape of

IV.—Descriptions of New Genera and Species of Eumolpide. 
By J..S. Baxy. 


Tue chaotic state of the Humolpidw, the crowd of species which 
remain unnamed and unarranged in our collections, and the want of 
generic landmarks, have induced me to select some of the more 
interesting for description, proposing in many instances new genera, 
of which I have briefly given the differential characters. 


Genus BasttEpra. 


Caput exsertum, facie subelongata, fere perpendiculare ; ocwlis prominen- 
tibus, rotundatis, integris ; antennis gracilibus, filiformibus, corpore lon- 
gioribus, articulo tertio quarto fere dimidio breviori ; palpis maxillaribus 
subfiliformibus, articulo ultimo angustato-ovato, ad apicem attenuato, 
Thorax lateribus marginatis, pone medium angulatis ; antepectoris seg- 
mento antero-lateral (fig. 1b) cuneiformi, apice acuto, angulo exteriori 
ad thoracis angulum anticum extenso. Seutellwm subtrigonatum, apice 
obtusum. l/ytra thorace latiora, oblonga, modice convexa. Pedes 
elongati, graciles; femoribus dimidio hasali attenuatis, filiformibus, 
dimidio apicali incrassatis, ampullatis, quatuor posticis subtus ante 
apicem dente acuto armatis ; fbiis gracilibus, extus ante apicem emar- 
ginatis; tarsis (fig. 1d) gracilibus, articulo primo duobus sequentibus 
equali; wnguiculo (fig. 1c) basi appendiculato. 

Type, Basilepta longipes, Baly. 


Basilepta longipes. (Plate I. fig. 1.) 

B. subelongata, valde convexa, nitida, supra obscure viridi-zenea ; pedibus 
elytrorumque tuberculo obscure piceis, corpore subtus antennisque (his 
basi fulva exceptis) nigro-piceis ; thorace lateribus angulato.—Long. 
2 lin. 

Subelongate, very convex, nitidous, above obscure metallic green, 
body beneath and the antennze (the fulvous base of these latter excepted) 
obscure pitchy-black; a large shining circular protuberance on the 
basilar space of each elytron, together with the legs, piceous ; attenuated 
base of four posterior thighs obscure fulvous. Head smooth above, 
forehead with a longitudinal groove; lower portion of face deeply 
punctured; antennee slender, filiform, longer than the body, three basal

joints obscure fulvous. Thorax rather longer than broad; sides pro- 
duced and angled just behind their middle, their hinder portion sinuate ; 
above transverse, convex, gradually thickened and gibbose towards the 
apex ; surface deeply rugose-punctate, interstices irregularly thickened ; 
gibbose portion nearly impunctate. Scutellum subtrigonate. Elytra 
much broader at the base than the thorax, nearly three times the length, 
slightly narrowed behind, convex ; each elytron with eleven rows of 
distinct punctate strive, the first abbreviated; on the posterior half 
of the elytra nearly all the strize become obsolete, whilst on the epi- 
pleura are two short additional rows, making the total number across 
that portion of the surface thirteen; humeral callus elevated into a 
short compressed ridge; on the basilar space, between the humeral 
callus and the suture, is a distinctly raised circular piceous protuberance, 
its circumference bounded by an indistinct circular groove, the surface 
of the protuberance smooth and shining, impunctate. Body beneath 
obscure nigro-piceous ; legs piceous, elongate, basal half of thighs 
slender, filiform, apical half flask-shaped, two posterior pairs armed 
towards their apex beneath with a fine acute tooth, basal half of the 
same thighs obscure fulvous; all the legs sparingly covered with long 
silky hairs. 
Hab, Borneo. v 


This insect, most remarkable from its slender, spider-like legs, 
has been sent in some abundance from the above-mentioned locality 
by Mr. Wallace. 


Genus SPILOPYRA. 


Caput exsertum, modice deflexum ; oculis prominulis, oblongo-ovatis, intus 
obsolete sinuatis; antennis modice robustis, subfiliformibus, articulo 
secundo obconico, tertio illo duplo longiori, articulo sequenti paullo 
breviori, quinque ultimis vix incrassatis ; palpis maxillaribus (fig. 3 m) 
articulo ultimo ovato, ad apicem attenuato. Thorax transversus, ante- 
pectoris segmento antero-laterali (fig. 86) brevi, transverso, Scutellum 
trigonatum, apice obtusum. lytra oblonga, postice paullo attenuata, 
convexa, ante medium gibbosa. Pedes robusti, subelongati, antici czeteris 
paullo longiores ; tarsis (fig. 3d) articulo tertio bilobato, fere ad basin 
diviso; wngue valido, wnguiculo (fig. 3 e) simplici, inermi. Prosternum 
(fig. 3 f) trapeziforme, elevatum, antice abbreviatum ; mesosternum 
(fig. 3) breve, transversum. Corpus oblongo-elongatum, convexum. 

Type, Splopyra sumptuosa, Baly. 


This splendid genus, lke its near neighbour Podontia, has quite 
the habit of a Chrysomela; but M. Lacordaire, in the introductory 
remarks to his ‘ Monographie des Phytophages,’ having separated 
the closely allied families of Chrysomelide and Eumolpide by the 
deeply bilobed third joint of the tarsi in the latter group, rigidly 
excludes all insects possessing that character from the former. In 


Mr. J. 8. Baly on the Eumolpide. 25 


deference therefore to his opinion, I have placed it for the present 
amongst the Humolpide, although it is so closely connected in other 
respects with the true Chrysomelide as almost to form a link be- 
tween the two groups. In addition to the general form of the body, 
the structure of the sternum, and above all, the simple claw (common 
to the great majority of Chrysomelide, but wanting, with this soli- 
tary exception, in the Hwmolpide), there is yet another important 
differential character, hitherto overlooked, uniting it to the Chry- 
somelide, and which, I believe, will become extremely useful in 
separating the two families,—I mean the form of the antero-lateral 
plate of the antepectus; this part, in all the Chrysomelide that I have 
as yet examined, is short and transverse, its hinder margin being 
entire, and not dilated posteriorly ; in the Humolpide (the present 
genus and Podontia excepted) the same organ is more or less trigo- 
nate or trapezoid, its posterior edge being produced backwards into 
an oblong or angular process. This process varies much in shape, 
and might often, I think, be made available in determining the 
limits of some of the genera in this difficult group of insects. 

The simple claw at once divides Spilopyra from Podontia, the only 
genus with which it can be confounded.

situated halfway between the humeral callus and the suture, the second 
placed on the humeral angle; an entire, slightly sinuous and deeply- 
grooved fascia just before the middle; a short, deeply impressed sub- 
sinuous band, situated immediately behind the middle, and extending

middle and apex, and running obliquely upwards nearly to the suture ; 
and lastly, a narrow line covering the posterior two-thirds of the 
suture itself. Body beneath variegated with bright metallic green and 
purplish cupreous ; legs rufous, the knees and tarsi bright metallic green.

Of this magnificent insect I know but two specimens—one in my 


own collection, the other in the cabinet of Mr. Bakewell.

ad apicem attenuato. Thorax subcylindricus, lateribus non marginatus ; 
antepectoris segmento antero-laterali (fig. 5b) subtrigonato, angulo pos- 
tico truncato. Scutellum trigonatum, lateribus sinuatum, apice trun-

body, slender filiform antenne, and incrassated anterior pair of 
femora will separate it from the latter.

Genus Apvoxus, Kirby. 


The Rev. W. Kirby, in his work on the North American Coleoptera, 
has formed a genus for the reception of the non-metallic, hairy species 
of Eumolpus, taking for his type American representatives of our 
European Eumolpus vitis ; I have therefore retained his name, in pre- 
ference to the commonly used but more recent one of Bromius*.

will be either uniques, or, belonging to others, cannot therefore be 
mutilated by dissection ; but as every new genus will be figured, it 
is hoped that the absence of the usual analyses will not create any 
difficulty. Practically, we are satisfied with referring species to 
their genera from their external resemblances; but although it is 
very often quite impossible to ascertain the affinities of an insect 
without dissection, there is the danger of attaching too great import- 
ance to organs whose characters cannot always be determined satis- 
factorily, and which, moreover, because they occur in one species, 
are sometimes erroneously assumed to be present in others. Indeed, 
it may be doubted if even individual species are so invariable as to 
justify the minute descriptions of many naturalists. 

While believing in the existence of genera quite as much as in the 
existence of species, is it satisfactorily established that they can 
always be distinguished by technical characters, such as we are in 
the habit of employing? In all large genera, I believe, it will be 
eventually found that they possess no one character in common that 
is not also possessed by the group or family to which they respect- 
ively belong, and hence it is quite natural that the limits of such 
genera cannot be very strongly defined. This is especially the case 
in the Longicorn families, which with endless differences in habit 
agree in a certain similarity of details, so that the generic characters 
often become mere questions of degree,—while, on the other hand, 
many Heteromera alike in habit are found to vary remarkably in 
structure, and in fact to belong to very different groups than those 
in which their general appearance would seem to place them. 

These and other points of the same kind will be often exemplified 
in the course of these ‘ Notices ;’ but in considering the difficulties 
which beset all attempts at a satisfactory limitation and arrange- 
ment of species into families, genera, &c., it will be as well to bear 
in mind the remark of our great naturalist,—*‘ Nature is less of a 
systematist than Man.”

Omophron Brettinghame. 
O. ovato-rotundatum, nitidum, testaceum ; capite, prothoracis disco, ely- 
trisque (marginibus exceptis) viridi-eneis. 
Hab. India (Dacca). 

Shortly ovate or nearly orbicular, moderately convex, very smooth and 
shining ; head sparingly punctured, brassy-green ; labrum, epistome, and 
sm‘#ll triangular spot above the latter brownish-testaceous; prothorax 
finely and remotely punctured, and with the elytra rich brassy-green, 
bordered externally with testaceous,—the border much wider on the 
latter, which are also very finely punctured in rather distant rows; 
eyes and tips of the mandibles dark brown; antenne, palpi, and legs 
pale testaceous; body beneath with the sterna pitchy, the abdomen 
deep testaceous. Length 2 lines. 


For the possession of this and many other Coleoptera from the 
same locality, I am indebted to Dr. Ernest Adams of University 
College, the author (inter alia) of some exceedingly interesting 
and learned papers on the “ Vernacular names of Insects,” in the 
Transactions of the Philological Society, who received them from 
India*, where they were collected by Mrs. Brettingham (to whom I 
have dedicated the exquisite little Omophron just described) in the 
compound attached to the quarters of Charles Brettingham, Esq., in 
medical charge of the Kamroop Regiment of Native Infantry sta- 
tioned at Dacca. They comprised above seventy species, belonging 
to nearly as many genera. Of these there were only six or seven 
that were not represented in Europe, viz. Adoretus, Heteronychus, 
Anisotelus, Macratria, a Nitidulid, and two, or perhaps three, obscure 
Heteromerous genera, which I have not been able to refer to any 
hitherto published. Except that there were very few Staphylinide, 
they were mostly such forms as would be found in this country in 
the débris of a flood; and it is, therefore, most likely that they 
were collected in the rainy season. Dacca is nearly in the latitude 
of Calcutta, lies very low, and as it is subject to mundations from 
the Ganges, it is probable that it affords a larger proportion of 
European forms than would have been the case im a drier or more 
elevated district. So little is really known of the Entomology 


* Upwards of a thousand specimens, some nearly an inch long, although gene- 
rally much smaller, enclosed in two large-sized pill-boxes, were transmitted by 
post in the ordinary way in a single letter. A wine cork hollowed out in the 
middle, and a little trimmed at the sides, would be an excellent, and at all times 
available substitute for a box.

of India, that it would be premature to speculate as to its cha- 
racter ; but although in its animal productions there is a remark- 
able amount of Northern temperate forms, they could never haye 
been expected to predominate to such an extent in any one group, 
as it now appears they do, judging, however, solely from the facts 
here stated*. There is one point in connexion with this subject 
which can only be just alluded to here, viz. the apparent tendency of 
animals to migrate to the south, and not the reverse, or very slightly 
sot. The idea first occurred to me in noticing the very few Austra- 
lian forms of Coleoptera occurring in Mr. Wallace’s Indian Island 
collections contrasted with the number of these Indian forms in 
Australia, especially its northern parts;—compare also Natal with 
the Cape, or the United States with Mexico or Cuba; notice Upper 
Egypt, Arabia, Persia, &c., just receiving a tropical form here and 
there.

Casnonia aliena. 


C. picea; capite infra oculos profunde lunato-impresso; prothorace 
capite breviore, postice transverse corrugato; elytris leviter striatis, 
singulo macula flavescenti apicem versus ornato. 

Hab. Australia (Moreton Bay). 

Pitchy, shining; head rather broad, a deep semicircular impression 
between the eyes and the epistome ; prothorax not so long as the head, 
somewhat elliptical, smooth anteriorly, but with delicate transverse 
folds behind ; elytra about the length of the head and thorax together, 
and three times the width of the latter at its base, faintly striated with 
an oblong yellowish patch towards the apex of each; antenne dark 
brown ; legs pitchy, femora at the base and tibize in the middle (nearly 
obsolete, however, in the anterior pair) testaceous-yellow ; body beneath 
pitchy-brown, shining. Length 5 lines. 


Although the genus Casnonia is found in India as well as in 
South America, this is, I believe, the only species yet detected in 


* While this sheet was passing through the press, Dr. Adams received another 
collection from Dacca, evidently made in a more favourable season ; still, although 
there is an addition of many tropical genera, Huropean vastly predominate; and 
it is worth notice, that nearly all these tropical genera have a very wide range, as 
for example, Anthia, Chrysochroa, Protetia, Xylonychus, Cerosterna, Olenocamptus, 
Glenea, Apomecyna, Batocera, Xylorhiza, &e., all of which are represented by the 
commonest species.

and Australia are concerned.

The present insect is rather larger, with a shorter thorax, than any 
Casnonice that I am acquainted with. 


Sostea | Parnidee ]. 


Head small, completely retractile within the thorax. Antenne re- 
ceived, in repose, in a cavity beneath the eye ; 11-jointed, the first very 
large, laminate, the second dilated inferiorly, the remainder forming a 
compact flabellate mass. Eyes rounded, entire. Mandibles bidentate at 
the apex. Maxillz with lobes, short and broad. Maxillary palpi short, 
the last joint very large, cylindrical; the labial claviform. Mentum 
transverse, lobed in front. Labium dilated anteriorly. Prothorax 
transverse, convex, nearly semicircular. Elytra ovato-triangular, very 
convex, gibbous towards the base. Legs slender, coxz distant, tarsi 
short. Prosternum received in a notch of the mesosternum. 


These characters are drawn up exclusively from S. Westwoodu ; 
but the other species so completely resemble it, that there can be no 
doubt as to their generic identity. In all, the elytra have nine rows 
of punctures on each. The structure of the antenn will be better 
comprehended by the figure* than by any description, but owing to 
their minuteness, I was unable to detach completely the large basal 
joint; when in repose it appears to act as a valve, closing in entirely 
the rest of this organ: all the joints composing the flabellate mass 
are what may be called boat-shaped, except the last, each being re- 
ceived at its base, and for the greater part of its length, in the con- 
cavity of the preceding one,—the first, however, beg so much more 
dilated as so far to enclose the succeeding or fourth joint, that it is 
only visible at its free extremity ; and unless this is attended to, the 
antenne will appear to be composed of ten joints only. 

I have dedicated the first species to J. O. Westwood, Esq., M.A., 
F.L.S., &e., and have adopted his views respecting the position of 
the genus, of which, indeed, there can be no doubt.

hairs; prothorax covered with a short thick greyish pile; scutellum 
triangular; elytra deep indigo-blue, shining but slightly, with a pale, 
thin pubescence; legs ferruginous. Length 1 line. 

Resembles the last, but is smaller, with a very decided pubescence,

Byrsax [ Colydiidee]. 

Head small, vertical, hidden above by the prothorax. Eyes large, 
rounded, partially divided by the cheek. Antennze retractile, short, 
gradually increasing upwards; the first joint rather slender, the second 
shortest, the third and fourth longest and equal, the fifth triangular, 
the sixth to the tenth transverse, the eleventh shortly ovoid. Labrum 
and epistome very small. Palpi short, linear, the terminal joint ovate. 
[ Mentum transverse ; labium oblong, entire, as seen 7” setu.| Prothorax 
very transverse, gibbous in the middle, bicornuted anteriorly, the mar- 
gins dilated and crenulate. Elytra short, very convex, tuberculate, 
with broad crenulate margins. Legs of moderate size; tarsi with the 
first three joints very short, equal, with fine hairs beneath. Prosternum 
strongly compressed. Mesosternum toothed. 


In habit this genus closely resembles the Diaperis horrida, Ol., 
with which Mr. Walker’s Asida horrida is probably identical. Its 
real affinity, however, if we are to be guided by the tetramerous 
tarsi, is with Endophleus, Pristoderus, and some other little-known 
and even undescribed forms among the Colydiide, but differing from 
all in its head being perfectly hidden by the prothorax when viewed 
from above*.

finely punctured; prothorax smooth, even, with minute areolated 
punctures, its anterior angles rounded ; scutellum very large, triangular ; 
elytra with a nearly rounded outline, the base towards the shoulders 
very slightly convex, covered with delicate elongate punctures; an- 
tennze, palpi, body beneath, and legs, where not exposed when the animal 
is rolled up, ferruginous. Length 14 line. 


The occurrence of a genus so purely American as Sphwromorphus 
in Borneo may well excite surprise, as, @ priori, it might have been 
supposed, if any of that group occurred at all in the Indian Archi- 
pelago, it would have been either a new form, or the Madagascar 
Synarmostes. I cannot, however, find, from dissection of S. acromialis, 
any variation of character sufficiently marked to warrant its separa- 
tion from Spheromorphus. Dedicated to Mr. A. Wallace, to whose 
researches in the Indian Archipelago we owe so much.

head with numerous shallow punctures, dark bluish-green ; prothorax 
transversely corrugated, brassy-black ; scutellum covered with white 
hairs; elytra rather elongate, a little contracted posteriorly, closely

Scrobiger albocinctus. 
S. ater; prothorace subtilissime punctato; elytris fasciis duabus albis, 
una subobsoleta, altera, pone medio, obliqua. 
Hab. Moreton Bay. 

Nearly allied to S. cdoneus, Newm., but the eyes are smaller and less 
prominent, the prothorax more finely punctured, the anterior band on 
the elytra nearly obsolete and more median, and the posterior directly 
oblique, not curved. Length 5 lines. 


Cormonss [ Cleridee]. 

Head rather short, broad in front. Eyes ovate, vertical, scarcely emar- 
ginate. Antenne as long as the thorax, arising laterally in front of the 
eyes, 11-jointed, the first largest, the second shorter than the third, 
the last three forming a slender pointed club. Palpi with the terminal 
joint of the labial securiform, of the maxillary cylindrical. Labrum 
small, hairy. Prothorax subdepressed, rounded in front and at the 
sides, contracted posteriorly,—the pronotum confounded with the para- 
pleura. Scutellum transverse. Elytra depressed, narrowed at the base, 
gradually expanding at the sides, with a strongly marked carina at the 
shoulder, but no humeral angle. Wings none. Legs stout, femora 
clavate, tibise and tarsi short, the first tarsal joint nearly covered above 
by the second; claws simple. Abdomen of five segments. 

Although very dissimilar in habit to the Cleride in general, there 

is no doubt that this genus is closely allied to Natals. It is, I 

believe, the only one of its family without wings,—a condition due, 

as Mr. Darwin tells us, in reference to other insular apterous Co- 
leoptera, to “ the action of natural selection, but combined probably 
with disuse,” and therefore it would not, perhaps, be very difficult 
for the advocates of his theory to suppose Cormodes a descendant of 

Natalis, to which it certainly bears a very peculiar resemblance. 

The absence of a real humeral angle, but its simulation by an ele- 

vated and narrow carina (absent in all other Cleridz), and the, in 

other respects, well-developed elytra, do not appear to lead to the 
conclusion of the gradual reduction of the wings which such an ex- 
planation implies, because corresponding with this. presumed reduc- 
tion we have an unaccountable and apparently unnecessary increase 
of the elytra, combined, however, with the absorption of the humeral 
angle. I possess a Longicorn, closely allied to Mr. Wollaston’s oceanic 
genus Deucalion, also without humeral angles, but having perfect, 
although excessively small, wings, and of course entirely useless for 
the purpose of flight; but in this case the wings might at any time

disappear from physical causes alone, just as we find certain species 
of Hemiptera becoming apterous in cold localities or in very cold 
seasons. In these and other instances of abnormal variation, which 
in almost every case seem to have some speciality of their own, we 
look in vain for the “advantage ’’ which is supposed to have been 
acquired in the “ struggle for life.” An insect so suggestive of Mr. 
Darwin’s theory should appropriately bear his name.

Aulicus instabilis, Newm., the type of the genus, is such a variable 
insect, that it is quite possible this may be but one of its protean 
forms ; nevertheless, besides its smaller size, it is more convex, the 
prothorax narrower and less depressed, its greatest breadth being 
behind the middle, and the posterior and anterior margins being 
nearly equal; its head is also shorter, the eyes proportionally larger, 
and the antennz longer; moreover I have never seen any specimen 
of A. instabilis approaching this in colour.

Tenerus telephoroides. 


T. subangustatus, ater, nitidus; prothorace, articulo basali antennarum,

Hab, Australia (Moreton Bay). 

Rather narrow and depressed, black, shining, finely punctured, 
covered with short setulose hairs; head scarcely as broad as the pro- 
thorax, black; oral organs and palpi yellow, except the tips of the man- 
dibles, which are black; prothorax reddish-yellow, the anterior border 
black, three mammillated prominences on the disc, placed transversely ; 
scutellum small, black; elytra deep black, shoulders rather prominent ; 
femora and tarsi black, coxee and tibie yellow; antenne black, the 
basal joint yellow; body beneath black, shining, except the prothorax, 
which is yellow. Length 3 lines. 


The joints of the antenne are strongly produced on one side, as 
in the majority of the species of this genus, beginning from the 
third. I have only seen a single specimen, which is in my own 


collection. 
CuorEsive [ Cleridee]. 


Head small, transversely triangular in front, slightly exserted behind. 
Eyes rounded, prominent, entire. Antenne 11-jointed, linear, not half 
the length of the body, arising in front of the eyes; the first joint twice 
as long as the second, which is only a little shorter than the third, the 
fourth and fifth slightly longer, the rest subequal. Labrum transverse, 
entire. Mandibles strongly curved, bidentate at the apex. Palpi clavi- 
form, the joints very short and transverse, the maxillary much larger 
than the labial. Maxille rounded, two-lobed. Labium obovate. Pro- 
thorax subquadrate, constricted posteriorly before the base; pronotum 
distinct from the parapleuree. Scutellum small, triangular. Elytra 
convex, nearly hemispherical, advancing at their insertion on the base 
of the prothorax. Legs slender; first joint of the anterior tarsi nearly 
covered by the second above; the middle and posterior tarsi with all 
the joints free, the three intermediate of all furnished with lamella. 
Abdomen slender, of six ? segments. 


The habit of this very remarkable insect approaches in some 
respects the Melyrideous genus Chalcas ; the structure of the tarsi, 
however, is that of a Clerid, and although a very isolated form, I see 
no difficulty in placing it in the subfamily Enopline.

Dotrema ['Tenebrionidee }. 


Head short, transverse. Eyes lateral, contiguous to the prothorax, par- 
tially divided by the antennary orbit, larger below than above. Labrum 
small, rounded in front. Mandibles thin, triangular, bidentate at the 
apex. Antenne short, perfoliate, moniliform, and gradually increasing 
in thickness from the fourth joint to the seventh or eighth. Mentum 
subquadrate. Labium small, entire; labial palpi stout, clavate, the 
maxillary with its terminal joint subsecuriform. Maxillee two-lobed, the 
lobes ciliated (the inner armed*?). Prothorax depressed, contracted 
behind, broadly emarginate in front, its anterior angles rounded. Elytra 
very depressed, parallel, abruptly bent down at the sides; the epipleural 
plait narrow, terminating before reaching the apex. Legs short; cox 
distant ; tibize spurred, the anterior serrated externally ; tarsi slender, 
the first joint of the posterior as long as the last. Pro- and mesosterna 
broad and flat, the former rounded posteriorly, and received into a slight 
emargination of the mesosternum. 

A remarkable genus, which might readily be taken for a Pla- 
tisus, but which is very closely allied to, if not identical with, 
Mr. Wollaston’s Adelina. As, however, the characters of his genus 
were drawn up from an insect which he suspects may not be con- 
generic with certain representatives in the British Museum of 
M. Cheyrolat’s original, but unpublished Adelina (but which unques- 
tionably includes the species now to be described), and his detailed 
description differs in several, although somewhat secondary points, 
from that given above, and he has taken no notice of the peculiar 
elytra, I have thought it better to consider my species the type 
of another group; and I do so with less hesitation, as the name of 
Adelina has been long preoccupied by a genus of Gasteropods. 
Doliema, thus restricted, has a remarkable range, D. platisoides oc- 
curring in Ceylon, Manilla, and the Moluccas, while a closely-allied 
species, differing in nothing apparently but in having a somewhat 
broader head, is found in the valley of the Amazons.

Stilpnonotus eurypiformis (named, but not described, by Mr. G. R. 
Gray in the English edition of the ‘ Régne Animal’) appears to me 
to be referable to Mr. Kirby’s Zurypus, a genus not alluded to by 
M. Lacordaire in his great work. Mr. Kirby’s species, EZ. rubens, 
from the figure, seems to be a much broader insect than the present, 
which it is not impossible may be identical with Olivier’s Tenebrio 
nitens. The pronotum is confounded with the parapleurs, and the 
anterior cox are contiguous and greatly exserted, two characters 
which do not accord well with the Tenebrionide: the possession of 
antennary orbits forbids its association with Lagriide. In habit it 
is slightly assimilated to Camaria. 


(Kpemutes [ Helopidee }. 


Head transversely subquadrate ; epistome large, deeply inserted in front. 
Labrum short, transverse, broadly emarginate. Eyes rather broad, sub- 
lunate. Last joint of the labial palpi securiform, of the maxillary nar- 
rowly triangular. Antenne very short, clavate, 11-jointed, the first 
joint nearly concealed by the antennary orbit, the second short, third 
longest, the rest gradually increasing in breadth to the seventh, which, 
with the remainder, forms a sort of club. Prothorax transverse, slightly 
convex, carinated at its sides, the base closely applied to the elytra. 
Scutellum small. Elytra ovate, very convex. Legs rather short; an- 
terior femora strongly toothed; tibiz slightly curved; tarsi very short, 
the last joint longer than the rest together. Prosternum received in a 
notch of the mesosternum. 


Very near Spherotus, from which it differs in the antenne and

Brassy-green, somewhat iridescent ; head and prothorax finely punc- 
tured, the former with a semicircular impression above the epistome 
(common apparently to the genus); scutellum small, rounded poste-

Exacatis [Melandryide ]. 


Head broadly triangular, as wide as the prothorax. Eyes distinct, large, 
ovate, contiguous to the prothorax. Antenne arising from beneath a 
narrow orbit, eleven-jointed, the two basal joints thick, the second 
shortest, the third to the eighth subequal, slender, the last three forming 
a short ovate club. Labrum small, rounded anteriorly. Mandibles 
short, with a single tooth in the middle. Palpi robust, claviform. 
Maxille with two ciliated lobes. Labium small, subcordate. Mentum 
transverse. Prothorax subquadrate, posterior angle emarginate, the 
parapleure distinct. Elytra as broad as the thorax, tapering posteriorly, 
the epipleural plait very narrow. Legs short; anterior coxe conical, 
contiguous, their acetabula closed behind, the intermediate subapproxi- 
mate, oblique, furnished with trochanters, the posterior transverse ; 
tibiee spurred; tarsi very slender, the first joint long, the penultimate 
entire; claws simple. Mesosternum narrow, truncate behind. 


Genera and Species of Coleoptera. 53 


I have not placed this genus among the Melandryide without 
hesitation, on account of its antennary orbits, and its acetabula 
closed behind ; on the other hand, its parapleure, distinct from the 
pronotum, make its location in any other family still more difficult. 
Except the comparative shortness of the maxillary palpi, it agrees 
with the Melandryide in most of the characters given by M. Lacor- 
daire, according also in form with some of its genera, without, how- 
ever, being related to any of them. Like Tetratoma, it has the 
antenne terminating in a club, but only composed of three joints. 
In the drawing the maxillary lobes are much too large, compared to 
their palpus. 

Elacatis delusa. (Pl. II. fig. 5.) 


E. griseo-testacea, punctulata; elytris fasciis tribus dentatis, maculaque 
basali nigris. 
Hab. Borneo (Sarawak) ; New Guinea (Dorey). 

Greyish-testaceous, finely punctured, a short setulose hair arising 
from each puncture ; prothorax with three or four very minute teeth at 
the side, and a shallow transverse impression near the base ; scutellum 
long and narrow; elytra with three black, toothed bands, the first often 
interrupted or replaced by a few spots; a patch of the same colour, also 
sometimes broken up into spots, at the base near the scutellum ; 
antenne and legs testaceous-yellow, more or less clouded with brown ; 
body beneath ferruginous, slightly tomentose. Length 14-2 lines. 


My New Guinea specimen agrees perfectly well with those from 
Borneo ; but they all vary a little in colour, some being darker than 
others, and the black band and scutellar patch being more or less 
interrupted. A second species, and a much finer one, from the 
Moluccas, is in the collection of W. W. Saunders, Esq. 


Bropuipa [ Melandryide ? }. 


Head moderately long, tumid in front, suddenly contracted behind into a 
narrow neck. Eyes distant, lateral, reniform. Antenne arising close 
to the eye, filiform, half as long as the body, 11-jointed ; the second 
very short, the rest subequal. Labrum transverse, inserted below the 
line of the front. Labial palpi filiform; the maxillary elongate, with 
the last joint narrowly securiform. Prothorax depressed, semicircular, 
as wide as the elytra behind, its parapleure distinct. Elytra depressed, 
rather broader behind. Legs moderate ; anterior and middle cox con- 
tiguous, the former conical and elongate ; tibize spurred ; tarsi slender, 
the first joint of the four posterior as long or longer than the rest 
together, the penultimate bilobed; claws undivided, strongly toothed 
beneath. 


This is another of those puzzling genera, of which there are so 


54 Mr. F. P. Pascoe on some new or little-known 


many among the Heteromera; in its habitit resembles Scraptia ; but 
as the more important characters are those of Melandryide, and that 
family is also one which contains several anomalous forms, it seems 
less objectionable to place it in that group than in any other. 


Biophida unicolor, (Pl. III. fig. 4.) 


B. fulvo-testacea, pube pallidiori vestita; prothorace bifoveolato ; oculis

Hab. Natal. 

Entirely of a light-brownish testaceous colour, rather closely covered 
with short stiffish paler hairs; a large fovea on each side of the pro- 
thorax near the posterior angle; scutellum transverse, rounded behind ; 
eyes a little darker. Length 4 lines. 


Iscuaxt [ Pedilide ? }. 


Head small, contracted behind, and narrowed anteriorly below the eyes. 
Antenne shorter than the body, linear, 11-jointed; second joint smallest, 
the rest subequal. Eyes reniform. Epistome and labrum large, covering 
the mandibles. Maxillary palpi robust, the last joint securiform; labial 
much shorter, terminating in a broad triangular joint. Maxille short, 
obtuse. Prothorax narrowed anteriorly, irregular above, its posterior 
angles produced, the epipleurse confounded with the pronotum. Elytra 
broader than the prothorax, subparallel, bent at the side, and concave 
on the disc, the epipleural plait narrow. Legs moderate, anterior 
acetabula open behind; all the cox approximate, the anterior and 
intermediate conical; tibie unarmed; tarsi short, first jot longer 
than the rest together, the penultimate bilobed; claws simple. 

I refer this genus doubtfully to Pedilide, notwithstanding that it 
agrees in two characters which M. Lacordaire considers of high im- 
portance, viz. the anterior acetabula largely open behind, and the 
complete contiguity of the posterior coxe. The family, however, as 
it stands at present, is not a satisfactory one, and its learned pro- 
poser will probably see reasons for modifying it eventually.

antenne black, with the last three joints white; legs black; body beneath 
black, with a slight bluish tinge on the breast. Length 5—4 lines. 


The irregularity of the surface of the prothorax varies ; in extreme

cases it has the appearance of being shrivelled up by desiccation.

and prothorax finely punctured, the latter with the sides posteriorly 
nearly parallel; scutellum small, subtriangular; elytra very thickly 
punctured *, with a larger series of punctures arranged in closely set 
rows, which are divergent at the base; antennze and palpi tawny, the

and prothorax rather coarsely punctured, the latter with the sides gra- 
dually but very slightly contracting posteriorly; scutellum large, sub- 
quadrate; elytra finely punctured, a larger series in rows as in the last 
species ; legs (except the posterior tibi), palpi, and antenne tawny-

very finely punctured, the latter rather broad and somewhat ovate ; 
soutellum subtransyerse ; elytra punctured, &c., as in the preceding ; legs 
(except the posterior pair), palpi, and antennz fulyous, the latter with

Glossy black, with much-dispersed whitish hairs ; each elytron with 
two rather indistinct white or somewhat ashy spots, one a little before 
the middle, the other the same distance beyond it ; antenne, palpi, and 
mouth pale yellow, the former gradually deepening towards the apex 
into black; tarsi pale yellowish, except the first joint of the posterior 
pair. Length 3 lines. 


Emyvopss [ Lagriide ]. 


Head very small, rounded behind the eyes, then contracting into a neck, 
which is nearly immersed in the prothorax. Eyes large, oblong, emar- 
ginate, transverse, and approximating both above and beneath. Labial 
palpi very small; maxillary elongate, the terminal joint ovate, pointed. 
Antenne robust, shorter than the body, arising close to the eye, the 
first joint tumid, the second very short, the third to the tenth thick, 
triangular, with a bifid prolongation at the apex of each on one side, 
the eleventh elongate-ovate. Prothorax slightly transverse, rounded 
anteriorly, twice the breadth of the head, but much narrower at the 
base than the elytra, its parapleurze confounded with the pronotum. 
Elytra depressed, with a subovate outline, the epipleura strongly bent in 
beneath. Legs robust ; anterior coxe large, approximate, shortly cylin- 
drical; tibiee not spurred, the four posterior thickened in the middle ; 
tarsi short, the penultimate joint subbilobed; claws undivided, slightly 
toothed at the base. 


A very curious genus, which, if rightly referred to Lagriide (and of 
this I have little doubt), differs entirely in the remarkable structure 
of the antenne, in which it somewhat resembles the Pyrochroide. 
From my solitary specimen, I cannot make sure that the anterior 
acetabula are closed; they appear to be so, however. As far as I

can judge from the parts in situ, the mentum is subtriangular and 
the labium obcordate.

of the maxillary subcylindrical. Antenne short, linear, the joints 
slightly obconic. Prothorax transverse, narrowed in front. Elytra 
subdepressed, wider behind; the sides somewhat concave. Legs slen- 
der; tibize bicalcarate ; penultimate joints of all the tarsi small, tri- 
angular. 


Differs from Cantharis, with which only it is likely to be con- 
founded, in the short penultimate joint of its tarsi: the claws appear 
to be undivided, from the close application of their two divisions.

thickly and irregularly punctured; body beneath and eyes black; base 
of the first joint of the posterior tarsi whitish; spurs of the middle 
tibiee, and all the claws, except at their apices, yellow. Length 4 lines,

large white lunate patch, more or less spotted with brown, extending 
longitudinally on the middle of each elytron, with its convexity 
towards the suture, and extending externally to its margin, the apex 
also with a white patch of the same character; antennz pitchy-brown, 
slightly hairy; legs brown, annulated with white; body beneath dull

Dipicza Waterhousei, Pase., hitherto only known from Aru, unless 
indeed (as I have elsewhere suggested as regards the genus) the 
CEdecerus* bipunctatus of M. Montrouzier, from Woodlark Island, 
should be identical, in which case it will probably be found to be 
very generally distributed in those regions.

I have elsewhere mentioned my suspicions that this genus is syno- 
nymous with Dendropemon, Schon.,and M. Jekel is inclined to take 
the same view of it; as, however, the name was previously used by 
Perty, or what will be considered to amount to the same thing— 
for his orthography was Dendropemon—another name must be 
adopted, and Wessta having been applied to a group of Saurians, I 
have thought a modification of it to Messtara will be attended with 
the least inconvenience. Stenocerus platipennis! Montrou., is evi- 
dently nearly allied to the species just described, and his three other 
Stenocert probably belong likewise to this genus. S. Garnotii, Guer.,

Hab, Moreton Bay. 

Elongate, subcylindrical, with a short dark brown tomentum, slightly 
varied with greyish-white ; head shortly ovate, eyes rather large ; pro- 
thorax a little longer than wide, varied anteriorly and at the sides 
with greyish; scutellum minute ; elytra punctate-striate, the alternate

well as behind the middle, elongate, forming an indistinct, oblique, 
band-like mark; antennez dark brown; legs paler, varied with greyish ; 
body beneath greyish-brown. Length 3 lines. 


This species, together with B. peregrinus and B. ingratus from 
Port Essington, described by me in a recent number of the ‘ Annals 
and Magazine of Natural History’ (Dec. 1859, pp. 432, 433), &e., 
differ from B. nitidicutis, Jekel, the type of the genus, in their nar- 
rower and more elongate form, and their brown, not ashy, colour. 


Dryorwopara [Curculionide ]. 


Head small, abruptly contracted below the eyes into a short rostrum. 
Eyes large, round, prominent. Antenne short, straight, arising close to 
the eyes in a cavity formed between them and a short thick process, 
twelve-jointed, the first subpyriform, elongate, the second shorter, sub- 
cylindrical, the third to the eighth slender, gradually diminishing in 
length, the last four forming an ovate compact club. Prothorax sub- 
triangular, lobed at the base, narrow anteriorly, irregular above. Elytra 
large, much wider than the prothorax at the base, very irregular and 
spinous. Anterior and intermediate legs moderate, the femora clavate 
and unidentate beneath, each tibia with a single curved spur; the 
posterior longer, their femora slender at the base, abruptly clavate at 
the apex, and armed with a strong tuoth, their tibiz strongly com- 
pressed and curved; the tarsi of all short, the penultimate joints 
broadly lobed; claws toothed beneath; anterior coxz approximate, 
intermediate and posterior widely apart. Meso- and metasterna very 
large. 


The affinity of this genusis no doubt with Tachygonus, and judging 
from its posterior legs, it is probably also saltatorial. As the import- 


62 Mr. F. P. Pascoe on some new or litile-known 


ance of the geniculation of the antenne is now only recognized as a 
secondary character, I think M. Jekel* has done good service in 
referring all the groups of Schonherr’s Orthocerati, after eliminating 
those which evidently belonged to the true Curculionide, to four 
families. Tachygonus is one of the genera so removed, and this 
M. Jekel seems inclined to place near Ceutorhynchus. :

From the slender and elongated tarsi, particularly the posterior, I 
should be inclined to refer this genus to the neighbourhood of 
Edopeza, rather than to Monohammus, where formerly I had doubt- 
fully placed it. Except the slightest possible variation in the patches 
on the elytra, there appears to be no difference between the Batchian 
and Dory insects.

VI.—Deseriptions of new Genera and Species of Exotic Hymenoptera. 
By Freperick Suirs, Esq., Assistant in the Zoological Depart- 
ment of the British Museum. 


Suvce the publication of the ‘ Catalogue of the Pormicide,’ in 1858, 
I have described nearly two hundred new species belonging to that 
family, the whole being inhabitants of the Eastern Archipelago. I 
have not described, since the above period, any Ants from other 
localities; the consequence has been, that many interesting and 
some remarkable species have accumulated which are new to science ; 
a portion of these I purpose describing in the present paper, and 
also figuring some of the more remarkable forms. I hope to add 
additional interest to my work, by compiling a series of observations 
on the habits of some of the species, from notes made on the spot by 
Mr. H. W. Bates, who has in so many ways added greatly to our 
knowledge of the entomology of Brazil. 

I think it will be readily admitted that no family in the wide 
range of the Insect world contains species which present such a 
wonderful diversity of forms as are to be found amongst the Formi- 
cide ; so great is it, indeed, that nothing short of actual observation 
could possibly lead the entomologist to suppose, in many instances, 
that any relationship existed between the different members of the 
same community. In my correspondence with both Messrs. Wallace 
and Bates, I have always impressed upon them the importance of 
collecting these insects from their nests, or under such circumstances 
as would warrant their being considered sexes of the same species ; 
to my request both these gentlemen have most willingly responded. 
A few species obtained under such conditions, are of more real ento-

mological value than hundreds of specimens taken at random, with- 
out even a local habitation or a name. 

Great as is our astonishment when we behold the endless diver- 
sity, I may add, the eccentricity of form in these remarkable insects, 
it will not for a moment bear comparison with the wonder which 
irresistibly seizes us when we are led into the details of their 
marvellous individual economies. Wonderful, doubtless, are many 
monuments of engineering skill—vast tunnels excavated under lofty 
hills, or hewn through solid rocks —mighty pyramids heaped up 
thousands of years ago; but the Ant (@codoma), ages preceding 
the epoch of the construction of our tunnels, or of the marvels of 
Egypt, bored her highways beneath the rivers of Brazil, and raised 
her mounds, which, when compared with the tiny architects, out- 
strip even the gigantic pyramids themselves. 

The three genera treated upon in the present paper are each 
remarkable for readily distinguished characteristics: Cryptocerus 
especially for the endless diversity of form in the different species, 
and many of the species for the extraordinary differences in the 
sexes of the same community. 

The species of the genus Pseuwdomyrma are distinguished by their 
elongate form, petiolated abdomen, and by the greatly enlarged eyes of 
all the sexes, in many species occupying the entire sides of the head. 

In the genus Heiton we have the reverse of the genus Pseudo- 
myrma; at least it is so in the only sex yet discovered—the worker ; 
in these the eyes are so small, that, except in two or three species, 
they cannot be seen without a high magnifying power, whilst in 
three species I have been unable to discover any eyes at all. I shall 
now proceed to give some account of the habits of the genera, in the 
order in which I have here enumerated them. 

The habits of a few species of the genus Pseudomyrma have been 
observed: most of these excavate the pith from dried twigs; in the 
tunnels or burrows thus formed the eggs are laid, and the young 
brood developed: the communities are small, frequently not more 
than twenty, exclusive of larve and pups. One species, P. termi- 
taria, constructs its nest, or more correctly, takes up its abode, in the 
tumuli of different species of Termes: others form small elliptical 
chambers in the outer walls of Termitaria, a single colony only 
apparently occupying each chamber ; these are usually wide apart, 
and do not appear to contain communities which have any connexion 
with each other. The pupz of this genus of Ants do not spin 
cocoons. The insects, when at large, are to be seen coursing rapidly 
over trees and herbage ; their sting is very slight. 


of Exotic Hymenoptera. 67 


The species of the genus Hciton are very abundant, and cannot 
fail to attract general attention ; we are now acquainted with about 
twenty species. The processions of these insects are of common 
oceurrence; and the different colours of the species are very obser- 
vable when the lines are seen upon the march, some, as Mr. Bates 
remarks, appearing like “a liquid stream of metal.” These Ants 
are regular clearers of all animal matter, living or dead: when on 
a foraging expedition, they spread out their columns, climbing over 
every leaf, plant, shrub, and tree, putting the whole animal as well 
as insect world into commotion and alarm; should any decaying 
mass of vegetable matter fall in their way, it is instantly covered 
with a living crowd, every chink and cranny is carefully searched, 
after which the army resumes its march. All apterous insects, par- 
ticularly Blattw and Spiders (the former being exceedingly nume- 
rous under fallen leaves, especially in their larva state), are preyed 
upon; the larve of Lepidoptera and Diptera fall an easy prey, as 
well as the species of Mormicide. At other times a community of 
Ecitons engage ina regular attack upon a nest of some peaceful and 
industrious species of Formica; the Heitons crowd into the nest of 
the ants, each seizing upon a helpless victim, and carry or drag it 
out of the nest; if the ant prove too bulky for a single Heiton to 
carry, it is ruthlessly torn into pieces, two or more assisting in the 
operation. The march is then commenced back to the nest of the 
Ecitons, the living ants and the mangled remains of others being 
probably conveyed there for the purpose of feeding the young brood 
of the marauders. 

Every community of Hciton consists of two distinct forms of 
workers, besides the males and females, In the typical species, /. ha- 
mata, the large worker, or soldier, is furnished with long, curved, 
sickle-shaped mandibles; there is no gradation either in the form 
of these organs, or between these larger ants and the ordinary 
smaller workers: these soldiers bear the proportion of about five to 
one hundred of the smaller individuals. In other species, such as 
E. vastator and E. erratica, described in the present paper, the 
soldier workers have the head greatly enlarged, with mandibles of the 
ordinary size ; but even here there is no trace of gradation between 
the two forms: it is true that the smaller form has individuals 
differing in size; so also, but in a less degree, do the big-headed 
soldiers differ in size; but between the two distinct forms there are 
no gradations which would unite them. 

Although the ants belonging to this genus are so numerous in 
Brazil that they cannot fail to attract the notice of the naturalist, 

F 2 


68 Mr. F. Smith on some new Genera and Species 


yet hitherto no one has been fortunate enough to discover either the 
male or female of a single species; ‘ their societies,” says Mr. Bates, 
‘are so numerous, and their sting so severe, that an attack upon one 
of their colonies is not to be rashly undertaken.” 

The species of the genus Cryptocerus are not unfrequently to be 
observed on low trees and bushes in dry open places, or running 
on branches of newly felled trees; they also visit flowers abundantly. 
The species generally are wood-borers, usually perforating the dead 
branches of trees. The males and females are winged, the latter only 
temporarily so. The typical species, C. atratus, has been observed 
to construct its nests in the dead suspended branches of woody 
climbers ; outside is seen a number of neatly drilled holes, but inside 
the whole solid wood is perforated with intercommunicating galleries. 
Each community appears to consist of a single female and two 
kinds of workers; the latter, in some species, are quite unlike each 
other, differing in the form of the head, and in the armature of 
the thorax and nodes of the peduncle. The species appear to be 
omniyorous, and are frequently attracted by the excrement of birds, 
These insects, like those belonging to the genus Myrmica, do not, in 
the pupa state, enclose themselves in cocoons. 

The new species of the genus Epomidiopteron, from Mexico, is ex- 
ceedingly interesting; the only one previously described was from 
Brazil. I also describe a new species of the rare genus Trigonalys, 
from Mexico; Shuckard has described one from South Carolina ; two 
are therefore known from North America, four have been discovered 
in South America, one in Celebes, one in Australia, and one in Europe, 
making in all nine species of this beautiful genus.

This ant constructs a papery nest, in texture and appearance like 
thin coarse brown paper ; it is usually attached to the underside of a 
leaf, and about 2 inches long by 1 inch broad ; the inner chambers 
are intricate and irregular: when alarmed, the workers issue forth 
in great commotion, making a curious rattling noise by vibrating 
their abdomens over the papery nest, apparently for the purpose of 
intimidating their enemies.

major, excepting that the mandibles are obscure fusco-ferruginous, not 
black ; the head narrower, more oblong, and slightly narrowed behind.

This ant I believe to be destitute of organs of vision. In the 
place where the eyes are usually situated, I discovered, with a high 
magnifying power, a minute pit. Mr. Bates observed that this 
insect showed a great aversion to light, taking every means of hiding 


from it. 
2. Eeiton erratica. 


£. opaca, rufo-fulva; capite maximo, in medio sulcato; mandibulis rufo- 
fuscis, longitudinaliter striatis; oculis obsoletis. 

Worker major, Length 33-4 lines. Rufo-fulvous, opake ; the head 
very large, subquadrate, rather longer than broad, with a central im- 
pressed line between the antennz running upwards nearly to the poste- 
rior margin of the vertex ; the head is delicately shagreened, and has a 
regular set of scattered punctures, in each of which is a pale, short, erect 
hair; the anterior margin of the head and the mandibles rufo-fuscous, 
the latter with a single tooth in the middle of its interior margin, and 
a number of erect pale hairs. Thorax finely shagreened and slightly 
pubescent; the legs pubescent. Abdomen subglobose; the nodes of 
the peduncle subquadrate ; the first with a short, stout, acute spine 
beneath.

Worker minor. Length 1-8 lines. Of the same colour and punctation 
as the worker major; small specimens are usually paler; all the indi- 
viduals have the head much narrower and longer than in the larger 
form, and it is also widest in front. The thorax at the sides in front 
is obscurely fuscous; this character is rarely observable in the large 
examples. The antenne in this species are rather longer than in 
E. vastator. 


Hab. Ega. 


The habits of this species are very singular; it does not, ike many 
other species, march in long columns, crossing open spaces, and climb- 
ing up trees and bushes, but constructs covered ways built of minute 
grains of earth, beneath the protection of which the lines of foragers 
march, when engaged in plundering other ants’ nests; if a gallery 
of this kind is broken into, the larger workers or soldiers rear their 
heads and gesticulate in a threatening manner. On examining this 
species under a powerful microscope, I could detect only an irregular 
pit in the usual situation of the minute eyes of this genus. 


Genus STRUMIGENYS, n. g. 


Head cordate; mandibles porrect, tridentate; eyes round, placed ante- 
riorly at the sides of the head, at the extremity of a broad, deep excava- 
tion; the antennz inserted in the excavation, into which they are 
received in repose; the flagellum 5-jointed ; the scape three-fourths of 
the length of the flagellum; the ocelli placed in a triangle on the 
vertex, obsolete in the workers. Thorax ovate, oblong, and attenuated 
posteriorly in the workers; the anterior tibiz only furnished with a 
single spine at their apex. Abdomen with two nodes, the first attached 
to the thorax by a short petiole ; both are subovate, the second twice the 
width of the first ; the abdomen subovate, and pointed at the apex. 


The genus Strumigenys is doubtless closely allied to the Daceton of 
Perty; these genera, with that of Orectognathus, form a small group 
of ants, which appear to me to lead into the family of the Crypto- 
ceride ; they agree with the latter insects in having the antenne 
placed at the sides of the head in a groove, into which they fall 
when in repose; they are also, like some species of Cryptoceride, 
more or less ornamented with scales.

S. rufo-ferruginea ; capite cordato ; abdomine levissimo, nigro. 

Female. Length 23 lines. Rufo-ferruginous; the head black and

margin; the antennz with the flagellum clavate, and pointed at their 
apex ; the head and antenn sprinkled with minute glittering semi- 
transparent pale scales. Thorax short, subovate; the scutellum semi- 
circular and prominent ; the metathorax abruptly oblique, deeply exca- 
vated behind; the legs with glittering scales. Abdomen subglobose, 
the apex pointed ; the nodes subglobose, the first petiolated ; the second 
segment obscure red ; the abdomen delicately aciculated longitudinally. 
Worker. Length 14 line. The head, thorax, legs, and nodes of the 
abdomen rufo-ferruginous, and sprinkled with minute glittering scales ; 
mandibles elongate, produced, with three long acute teeth; the head 
more elongate than in the female. Thorax elongate and narrowed 
behind; the thorax and legs sparingly sprinkled with glittering scales. 
Abdomen smooth, shining black.

This curious species is found, Mr. Bates informs me, running 
slowly and prowling about the bark of trees. 


Subfamily Arrmm, Smith, 


Genus Myrmicocrypta, n. g. 


Head oblong, narrowed anteriorly; eyes round and prominent; antennz 
inserted in the middle of the anterior part of the head, outside of two 
elevated carine ; the flagellum subclavate, increasing in thickness to the 
middle of the apical joint, which is pointed at the apex, and twice the 
length of the penultimate joint; the scape about one-fourth shorter 
than the flagellum, Thorax oblong, widest in the middle ; the anterior 
margin transverse, with the angles slightly produced; the scutellum 
deeply emarginate, forming a tooth on each side; the metathorax has 
also a tooth on each side; the superior wings with one marginal and 
one submarginal cell. Abdomen attached to the thorax by a petiole 
composed of two nodes; the first subglobose, the second cup-shaped, 
and as wide as the base of the abdomen. 


The affinities of this very singular and minute ant are somewhat 
difficult to assign. After a careful examination of the characteristics 
of those genera to which, on a slight inspection, it appeared to me 
most nearly related, I am of opinion that its situation in the family 
is next to, or in the immediate vicinity of, the genus @eodoma ; it 
agrees with the species of that genus in many important characters, 
namely, in the form of the mandibles, in the situation and character 
of the antennse, very closely in the venation of the wings, and in 
the intermediate and posterior tibize being destitute of spines at their 
apex. I have only seen one sex—the female ; the discovery of the 
males and workers will probably furnish other important characters, 
which may show the exact situation that the genus ought to occupy, 
should I not have assigned it its true one,

This insect is described as the worker of C. quadrimaculatus on 
the authority of Mr. H. W. Bates, who took them in their nest; of 
this species he remarks, “ The difference between the female and 
worker in form is very remarkable : I find a constancy in the spines, 
&c., in all the workers, showing that the species are constant in their 
characters: the female has a spotted abdomen.” The female is 
described by Klug in his Monograph on the genus; I have also 
described and figured it in the second volume of the ‘ Transactions 
of the Entomological Society,’ new series.

in repose; the antennze subclavate ; the scape as long as the funiculus, 
and grooved beneath for its reception; the funiculus twelve-jointed ; 
ocelli in a triangle on the vertex in the 9, but wanting in the 8; 
mandibles incrassate, produced, with their inner edge serrated. The 
thorax subovate in the 9, oblong and narrowed posteriorly in the 9; 
the superior wings with one marginal cell, open at its apex; one sub- 
marginal cell; the discoidal cells obsolete; legs stout and of moderate

Note.—In my ‘Catalogue of the Formicidae,’ I included this insect 
amongst those which form the genus Meranoplus. The species was 
received shortly before my work went to press, but the winged female 
has come to hand subsequently. The neuration of the wings is very 
different from that of the genus Meranoplus; I have therefore removed 
it from the genus in which I provisionally placed it. It is one of 
the most singular insects in the whole family of the Formicidae.

lique stripes behind them; the mandibles with their tips black; the 
antennze fulvous beneath and rufo-fuscous above. Thorax: the pectus, 
the mesothorax, and base of the metathorax above, black; the meso- 
thorax with two longitudinal yellow lines, which also cross the sides 
of the scutellum; a line over the tegule, the post-scutellum and two 
oblique lines beneath it, yellow; a black line down the centre of the 
metathorax; the wings flavo-hyaline, the nervures pale ferruginous, 
and a yellow spot on the tegule. The abdomen petiolated, entirely 
yellow, and very smooth and shining. 


This is a fine addition to the division of the genus Philanthus 
which has the abdomen petiolated, of which Klug has formed the 
genus T'rachypus ; but having hitherto adopted the neuration of the 
wings as the primary character of generic subdivision, I use Klug’s 
name merely as a sectional one. This insect was discovered by 
Mr. H. W. Bates at St. Paul, Brazil. Seven species of the petiolated 
Philanthi are now known.

VII.—On the Coleoptera of the Salvages. By T. Vernon Wottaston, 
MG AC SE DAS: 


Tux peculiar position of the almost inaccessible rocks of the Salvages, 
which le in the direct course from Madeira to the Canaries, though 
somewhat nearer to the latter than to the former, give them an espe- 
cial interest in the eyes of geographical naturalists,—particularly 
those, however, who have had an opportunity of studying the pro- 
ductions of the two neighbouring groups. The guestio vexata, as to 
whether these several Atlantic islands are not, in reality, the mere 
exponents or outposts of an immense continent now for the most 
part submerged, may perhaps never be solved; yet certainly one of 
the best methods of helping towards a solution is carefully to 
examine the fauna and flora of what seem to be its detached por- 
tions, and then closely to compare them with each other, in order to 
ascertain whether they possess sufficient in common (after every 
reasonable allowance has been made for the accidental intermission 


Mr. T. V. Wollaston on the Coleoptera of the Salvages. 85 


of specimens, from time to time, by chance agencies) to render their 
quondam connexion, thus far at least, probable. 

The small size of the Salvages, which consist of two uninhabited 
rocks (the minute third one being absolutely inaccessible) separated 
by a channel of about twelve miles, added to the great difficulty of 
approaching their few and dangerous landing-places*, render every 
fact concerning them, correctly arrived at, doubly valuable; and 
therefore I do not deem it necessary to apologize for these few pre- 
liminary remarks on an enumeration of the eleven species of Coleo- 
ptera which have been hitherto detected upon them. Six of these 
(apparently new to science, or at any rate treated by myself as such) 
were described in the ‘ Insecta Maderensia’ in 1854, and were due 
to the indefatigable researches of T. 8S. Leacock, Esq., of Funchal, 
who effected a landing on both of the islands during the spring of 
1851; whilst the remaining five (three only of which would seem 
to be novelties) have been lately communicated by my friend the 
Bariio do Castello de Paiva, who obtained them from the master of a 
Portuguese boat, which was freighted from Madeira for the purpose 
of gathering orchil and barilla, with which most of these Atlantic 
rocks more or less abound. In the following catalogue I do not 
undertake to pronounce for certain on which of the two islands the 
five recently added species were collected, though I believe them to 
be from the Great Salvage. Those discovered by Mr. Leacock were, 
he informs me, from the southern or smaller island,—known, never- 
theless, as the ‘ Great Piton.’

* T should add that, whilst accompanying my friend John Gray, Esq., to the 
Canaries, in his yacht the ‘ Miranda,’ two years ago, one of our main objects was 
to explore thoroughly these remote and almost unknown islands. Accordingly, 
sailing from Madeira on the 6th of January, 1858, we arrived off the Great 
Salvage on the following morning, and, after lowering the boat, pulled towards 
the rocks. The sea, however, ran so high, and the surf was so tremendous, that 
we found it impossible to approach nearer than a stone’s throw from the shore 
without the utmost danger; for the boat must have been literally dashed to 
pieces had we attempted to land. We therefore returned to the yacht (not 
without a “ ducking”), and resumed our voyage to Teneriffe.

Long. corp. lin. 34-33. 

T. head dark-piceous, and rather deeply punctured. Prothorax a shade 
paler, and more strictly piceous, and with the lateral edges more or less 
slightly rufescent; a little less deeply punctured than the head, but 
rather more rugose, especially about the hinder angles; abruptly trun- 
cated both before and behind, and much narrowed posteriorly,—the 
extreme hinder angles, however, being acute and prominent. Llytra 
subovate, much shortened behind, but nevertheless rather produced in 
the middle (¢. e. at their apical point of junction) ; somewhat acute at 
their humeral angles, much depressed, and most minutely and delicately 
alutaceous all over,—causing their surface to be a little less shining 
than that of the head and prothorax; regularly crenate-striate, and 
with the interstices rather distinctly punctulated ; testaceous, but orna- 
mented with two black or dark-piceous patches (common to both 
elytra) which cover the greater portion of the surface,—the first being 
comparatively small and transverse, placed at the centre of the extreme 
base, behind the scutellum, and reaching on each side to about (or a little 
beyond) the fourth stria, its portion between the third and fourth stria 
being more or less backwardly produced; and the second being im- 
mensely larger, postmedial, sometimes much suffused, and of a zigzag 
form, being produced both before and behind along the suture, and 
extending on either side to about the seventh stria. Antenne and 
palpi piceo-ferruginous ; and with the terminal joint of the labial palpi 
only very slightly enlarged and subclavate (instead of securiform, as in 
the ordinary Zarz). Legs testaceous. 


The three specimens from which the above description is com- 
piled have been lately communicated to me by the Barao do Castello 
de Paiva, to whom I have great pleasure in dedicating the species. 
From the close resemblance of their elytral patches and colouring to 
those of the Canarian examples of the 7’. discoideus, Dej., I had at 
first supposed them to be the exponents of a merely depauperated 
and slightly altered form of that-insect, from (perhaps) a long isola- 
tion on the small and remote rocks of the Salvages; but a more 
careful inspection has proved that such an opinion (as is too often 
the case in like instances) is only a superficial one, and that the two 
species are not only altogether distinct in their minor features, but 
even in their structural ones. Indeed, were it not that the speci- 
mens from the Salvages are essentially Tari in everything else, I 


Mr. T. V. Wollaston on the Coleoptera of the Salvages. 87 


should have been almost inclined to regard them as generically 
removed from their guasi-(Canarian) allies,—the scarcely expanded 
(and only slightly subclavate) terminal joint of their labial palpi (1 
believe, in both sexes) affording a marked difference from the immense 
and largely securiform corresponding one (at any rate in the males) 
of the normal members of that group; but as such is the case, I 
prefer treating them (at any rate for the present) as only very ano- 
malous Zari. As regards their more evidently specific details, they 
recede from the 7’. discotdeus in their smaller size and darker head 
and prothorax, the latter of which is more distinctly roughened and 
punctured, more straightly truncated before and behind, and is much 
more narrowed posteriorly (with the extreme hinder angles them- 
selves more prominent and acute); in their alutaceous and more 
shining elytra, which are shorter posteriorly (though rather more 
produced in the centre), with their shoulders more acute, and with 
their darker portions a little different, the basal patch being more or 
less backwardly-produced between the third and fourth stria, and 
the postmedial one larger and more suffused (extending on either 
side to the seventh stria, instead of only the sixth) ; in their darker 
palpi and antenne; and in their rather more coarsely serrated claws.

2. Pterostichus haligena, n. sp. 


P. apterus, niger, subnitidus ; prothorace subquadrato antice vix latiore, 
in disco canaliculato (canalicula antice et postice abbreviata et abrupte 
terminata), basi utrinque foveis duabus (una sc. interna angusta longi-

crenulato-striatis, singulo punctis duobus impresso, interstitiis planius- 
culis ; antennis pedibusque rufo-piceis. 

Long. corp. lin. 33-4. 

P. apterous, black, and slightly shining. Prothorax subquadrate, being 
but very little narrowed behind, and with the sides only very slightly 
rounded:; scarcely as broad, even anteriorly, as the elytra; with a deep, 
but abbreviated, dorsal channel down the disk,—it being suddenly 
shortened both before and behind ; and with two fovez on either side 
at the base,—the inner ones being rather long, deep, subflexuose, 
narrow and lineaform, and abruptly defined ; and the outer ones short, 
very broad and shallow (forming merely a depression). Elytra with 
their sides almost parallel, and (at any rate in the female sex, for which 


88 Mr. T. V. Wollaston on the Coleoptera of the Salvages. 


I can alone vouch) most closely and delicately alutaceous all over—(a 
structure which is very conspicuous under a high magnifying power, 
but which is only just traceable on the prothorax]; lightly and regu- 
larly subcrenate-striate, the striz being fine and narrow; with two 
punctures, just within the third stria, down the disk of each, and with 
the interstices rather flattened. Limbs rufo-piceous ; the antenne 
brighter at their base. 


The present Pterostichus, two female specimens of which have 
been communicated to me by the Bardo do Castello de Paiva, is 
closely allied to the P. canariensis of Brullé, which I haye taken 
abundantly in Lanzarote, Fuerteventura, and Grand Canary ; never- 
theless it is rather smaller and less brilliant than that insect,—the 
entire surface of its elytra (at least in the females, of which I can 
alone speak) being densely and distinctly alutaceous (a sculpture 
which is just traceable even on the prothorax also) ; its prothorax is 
a little less expanded anteriorly, and with its dorsal channel more 
abruptly terminated both before and behind; and its elytral striz 
are finer, narrower, and shallower, with the interstices much less 
convex,

H. oblongus, latus, subnitidus, niger vel nigro-piceus ; prothorace trans- 
verso, convexo, ad latera subzequaliter rotundato (basi haud constricto, 
sed paulo angustiore), utrinque leviter foveolato, angulis posticis ob- 
tusis; elytris leviter crenato-striatis (stria subsuturali abbreviata lon- 
giuscula) ; antennis rufo-ferrugineis, pedibus rufo-piceis. 

Long. corp. lin, 44-5. 

H. oblong, broad, shining (but not very brilliantly so), and black (or, 
when immature, piceous-black). Head rather large. Prothorax broad, 
transverse, and convex, almost equally rounded at the sides (¢. e., with 
the edges in a continuous curve,—not being suddenly attenuated, or 
constricted, posteriorly, though a little narrower behind than before) ; 
almost unpunctured, though with a shallow and obscurely punctured 
fovea on either side, at the base, behind. lytra lightly striated, the 
strie being finely but distinctly crenulated; with the abbreviated 
second stria longer than in the Madeiran and Canarian Harpali of this 
type, and completely joining the sutural one at a great distance behind 
the scutellum ; more truncated at their base than in the other Harpali 
of this type, the humeral angles being less porrected and more obtuse ; 
a little acuminated at their apex, but not minutely divaricate as in the 
H. vividus. Antenne rufo-ferruginous. Legs rufo-piceous. 


The Harpalus here described is one of a small cluster of Atlantic

forms,—four or five of which I have taken in the various islands of 
the Canarian archipelago, whilst another, the H. vividus (if, indeed, 
that insect be not in reality separable into more than a single 
Species), is universal throughout the Madeiran group. After a very 
careful comparison of the H. pelagicus with all the Harpali as yet 
detected both in the Madeiras and the Canaries, I am perfectly satis- 
fied that it cannot be referred to any of them; though it has a 
greater affinity, perhaps, with those of the latter islands than with 
those of the former. Apart from minor characteristics, it differs 
from them all in being rather broader throughout, as well as in the 
shape of its prothorax, which is wide, transverse and convex, and 
entirely unconstricted posteriorly (though a little narrower behind 
than before),—its edges being in a continuous curve, and with its 
angles therefore more obtuse than is the case in the allied species, 
Its elytra, also, have their shoulders less porrected or acute (the 
thickened line between the ewtreme apex of each humeral angle and 
the scutellum being almost straight) ; and their strize are much more 
perceptibly (though minutely) crenulated, and with the abbreviated 
second one longer than in any of the allied forms, and moreover 
completely joining the sutural one at a very considerable distance 
behind the scutellum. Three specimens of it have been lately com- 
municated by the Bardo do Castello de Paiva, to whose kindness I 
am indebted for the other novelties described in this memoir.

A single example of the common European C. centrimaculatum 
was lately communicated (along with the three preceding insects 
and the Blaps gages) by the Barao do Castello de Paiva, as coming 
from the Salvages. It is not a very important addition to the fauna, 
—for, being somewhat abundant both at the Madeiras and Canaries, 
the species may have been accidentally naturalized through the in- 
strumentality of the boats, which proceed there almost every year 
for the purpose of collecting orchil and shooting gulls.

A fine series of this noble Acalles was captured by Mr. Leacock,

allied to the Canarian A. argillosus, Schonh. (of which I possess 
several specimens, collected at Taganana and Orotava, in the north 
of Teneriffe),—though much larger than, and perfectly distinct spe-

The D. oceanicus is also due to the researches of Mr. Leacock, who 
secured a fine series of it (now in the Collection of the British 
Museum) on the ‘Great Piton,’ in 1851. It is a most interesting 
insect, as representing a group of which three* remarkably distinct 
exponents have been hitherto brought to light,—viz., one in the 
Madeiras, the Salvages, and the Canaries, respectively. The genus 
was established in the ‘ Insecta Maderensia,’ in 1854, to receive a 
very rare and anomalous Longicorn detected by myself on the extreme 
summit of the Dezerta Grande during January of 1859, and subse- 
quently by the Rev. R. T. Lowe and myself on the top of the almost 
inaccessible Southern Dezerta, or ‘ Bugio’; so that Mr. Leacock’s 
capture on the Salvages, of a kindred species, became at once a very 
significant and suggestive one. It is, however, rendered still more 

* T ought perhaps to say fowr, instead of three,—for a single (very old and 
imperfect) example of an additional species, closely allied to the Dezertan one, 
is in the collection of F. P. Pascoe, Esq.; but from what country it came, he is 
unable to state. If therefore it should turn out eventually to be likewise a 
native of one or the other of these Atlantic islands (which I cannot but regard 
as probable), we should have another confirmation of the geographical exclusive- 
ness of this curious Euceratic group. Another insect, from Lord Howe’s Island, 
in the South Pacific, has been described and figured by Mr. White, in the ‘ Pro- 


ceedings of the Zoological Society,’ under the name of Deucalion Wollastoni, 
but this belongs to a different, although nearly allied genus.

important now, through the discovery that the Lamia gibba of Brullé, 
peculiar to the Canaries, is in reality a Deucalion ; of which I have 
been able to satisfy myself, from the comparison of many specimens 
which I took during the spring of last year in Fuerteventura and 
Teneriffe,—from out of the decaying Euphorbias, on the stems of 
which the larvee would appear exclusively to subsist. And it is 
worth remarking that M. Brullé, whilst describing the Z. gibba in 
Webb and Berthelot’s ‘ Histoire Naturelle des Iles Canaries,’ in 
1839, implies his conviction that it would constitute eventually the 
type of a new genus: “ Espéce fort remarquable, et qui formerait 
peut-étre une division nouvelle dans le systeme proposé récemment 
par quelques auteurs.”

Taken in tolerable abundance by Mr. Leacock on the ‘ Great

Bardo do Castello de Paiva, which I believe to have been captured 
on the ‘Great Salvage.’ I have not yet compared it accurately 
with the many Hegeters which I have found during the last two 
years in the Canaries; but it evidently approaches very closely to a 
species which is common in most of the islands (particularly, how- 
ever, the eastern ones) of that group. Whether it will prove to be 
identical with it, or only nearly allied, I will not undertake to say 
at present ; but I must decide for certain when my Canarian material 
is sufficiently assorted for examination.

A single specimen of this beautiful Ditylus was discovered by Mr.

reason given under the Hegeter latebricola, I must decline at present 
to pronounce for certain whether or not it is identical with the 
D. concolor of Brullé, which I have recently captured in Grand 
Canary, Teneriffe, and Palma; but my belief is, that a careful com- 
parison will prove it to be conspecific with that insect. 


Such are the eleven species of Coleoptera which have been hitherto 
detected on these small and remote rocks; and it is interesting to 
remark, that they are each of them exponents of a separate genus,

and represent as many as nine families, whilst five of the species 
(v. e. nearly half of the entire number) are Heteromerous. Although 
it may appear absurd, at first sight, to speculate from such scanty 
data, it nevertheless is not difficult to decide, even from this material 
(which, after all, is considerable enough from islands thus minute), 
to which of the Atlantic groups these intermediate “ stepping- 
stones” are the more akin; for if we remove the Cercyon centri- 
maculatum and Blaps gages, which are common to both, from the 
above list, we shall perceive that, of the remaining nine, eight are 
most intimately connected with Canarian forms,—whilst two of these 
(the Hegeter latebricola and Ditylus fulvus) will, in all probability, 
be found to be absolutely identical with them. The Pterostichus 
haligena, moreover, 1s very nearly related to the P. canariensis, 
Brullé (belonging to a section, Orthomus, which apparently does not 
exist in Madeira); the Harpalus pelagicus is, emphatically, on the 
Canarian type; the Acalles Neptunus finds its natural ally in the 
A. argillosus of Teneriffe; the Deucalion oceanicus is more akin to 
the D. gibbus of the Canaries than to the Madeiran D. Desertarum ; 
and the Opatrum dilatatum is but shghtly removed from a representa- 
tive of the same genus which is found in Fuerteventura and Lan- 
zarote,—the Helops Leacocianus alone having perhaps more affinity 
with a species from the Madeiras (namely, the Porto-Santan H. in- 
fernus) than with any of those from the Canaries; though even of 
this I have by no means, as yet, completely satisfied myself. So 
that I think we may fairly conclude from these facts, that the Sal- 
vages, if indeed they are to be considered as belonging physically to 
either of the neighbouring groups, are essentially Canarian. 


VIII.—Deseriptions of six new species of Chrysomela from the East. 
By J. 8S. Baty. 


1. Chrysomela Templetoni. 


C. breviter ovata, valde convexa, obscure nigro-senea, nitida; elytris sub- 
globosis, obscure rufis, utrisque striis decem punctorum impressorum 
biseriatim dispositis instructis—Long. 31-4 lin. 

Very convex, obscure nigro-zneous, nitidous; elytra obscure rufous, 
Head nearly impunctate; antenne black, slender, more than half the 
length of the body, subincrassate towards their apex. Thorax twice 
broader than long; sides slightly dilated from their base to before the 
middle, thence rotundate-angustate to the apex: above smooth and 
shining, sparingly impressed here and there with fine but distinct 
punctures; sides thickened, bounded within by a longitudinal depres- 
sion. Scutellum semiovate. Elytra subglobose, smooth and shining, 


94 Mr. J. 8. Baly on.siv new species 


each impressed with ten rows of distinct punctures,. the first abbrevi- 
ated, the second running parallel to the suture, the others arranged in 
pairs, the puncturing of the outer pair more distant than in the rest, 
all the rows less distinct and nearly obsolete near the apex; outer 
margin impressed with a single row of fine punctures; interspaces 
smooth, indistinctly punctured. Body beneath finely punctured; legs 
slender, subelongate. 
Hab, Ceylon. 


The form of the elytra and the slender legs give this insect a 
different appearance from the rest of the genus. 


2. Chrysomela Fortunei. 


C. oblonga, valde convexa, nitidissima, iridescens; subtus viridi eneoque 
variegata, capite pedibusque purpureis ; supra viridi-gnea; capite tho- 
raceque rufo-violaceo-maculatis, hoc transverso, a basi ad ante me- 
dium ampliato, lateribus incrassatis, intra marginem profunde punc- 
tatis, irregulariter bi-impressis, disco levi, hic illic sparse punctato ; 
elytris dorso obsolete gibbosis, infra humeros transversim impressis, 
tenuiter punctato-striatis, punctis in striis confuse biseriatim dispositis, 
ad latera et apicem versus subdissipatis, interspatiis levibus; utrisque 
plaga magna male definita baseos, vittisque postice rufo-violaceis, vitta 
pone medium cezrulea.—Long. 5} lin. 

Oblong, very convex, almost gibbous just behind the middle, nitidous, 
iridescent; body beneath bright metallic-green, more or less inter- 
mingled with aureous; head and legs deep metallic-blue; above bril- 
liant metallic-green, variegated with rufo-violaceous. Head sparingly 
impressed with minute punctures; epistome semilunate, bordered above 
by a regularly curved line; antenne slender, deep metallic-blue. 
Thorax before its middle twice broader than long; sides gradually di- 
lated from their base to before the middle, thence suddenly rounded 
and narrowed to the apex ; upper surface sparingly impressed here and 
there with deep distinct punctures, sides thickened, bounded internally 
by a number of large, deep, confluent variolose punctures, placed longi- 
tudinally in the middle of which are two large, deeply impressed, ill- 
defined irregular fovez ; the basal margin and an irregularly curved 
marking on either side the disk, united with its fellow at the base, rufo- 
violaceous. Scutellum smooth, semirotundate-ovate. Elytra broader 
than the thorax, indistinctly dilated behind their middle, very convex, 
more particularly on the hinder half, their middle portion almost gib- 
bous; surface very smooth and shining, each elytron below the shoulder 
with a well-defined transverse impression, which extends from imme- 
diately within the outer border nearly to the suture; finely punctate- 
striate, the punctures on the strize irregularly arranged in a double 
row, the striz themselves, about nine in number, becoming confused 

_and irregular on the side and towards the apex of the elytron; inter- 
spaces on the disk smooth and nearly impunctate, those on the sides 


of Chrysomela from the Hast. 95 


and apex impressed with very fine remote punctures; whole surface 

distantly reticulate-aciculate ; a large irregular ill-defined patch at the 

base, nearly covering the space above the transverse groove, and four or 

five broad vitte, confluent at their base and apex, extending from the 

hinder margin of the groove to the apex of the elytron, rufo-violaceous ; 

in the centre of the hinder disk is also a short deep-metallic-blue stripe. 
Hab. Northern China. Collected by Mr. Fortune. 


This beautiful species is very closely allied to C. quadri-impressa, 
and when first received, I considered it as merely a local variety of 
that insect ; subsequently, however, it has been sent in some abun- 
dance, and after a careful examination of many individuals, I have 
come to the conclusion that it has a just claim to be considered a 
good and distinct species. It differs from C. quadri-impressa in the 
following characters:—it is larger, less regularly oblong, being 
slightly broader behind ; its convexity is greater, particularly on the 
hinder portion of the elytra, which are also obsoletely gibbous in 
their middle; the whole body is much smoother, far less closely 
and coarsely punctured; the punctate strize on the elytra are di- 
stinct over nearly the whole surface, whilst in the other species 
they are so mixed up with the coarse irregular punctation of the 
whole elytron, that they are only visible at the base; the thorax is 
more dilated on the sides, its disk is smoother and covered with much 
finer punctures, interspersed here and there with a few deeper im- 
pressions, which are much larger and more distinct than those in 
C. quadri-impressa ; lastly, the grooved line bounding the upper edge 
of the epistome, instead of being triangular, forms a regular curve. 


3. OChrysomela Stalit. 

C. ovata, convexa, nitido-cuprea ; thorace disco levi, impunctato, lateribus 
a basi ad paullo ante medium leniter ampliatis, hinc ad apicem rotun- 
dato-angustatis, incrassatis, intra marginem profunde punctatis ; elytris 
profunde punctato-striatis, punctis magnis, striis per paria subapproxi- 
matis, hic illic suleatis.—Long. 4 lin. 

Ovyate, convex, shining cupreous. Head finely but sparingly punc- 
tured. Thorax nearly twice broader than long; sides moderately di- 
lated from the base to just before their middle, thence rotundate-an- 
eustate to the apex: upper surface smooth and shining, convex and 
impunctate on the disk; sides incrassate, bounded within, for their 
whole length, by a broad but shallow longitudinal groove, the surface 
of which is covered with large, deep, round punctures; these, although 
somewhat crowded, are rarely confluent. Scutellum smooth, impressed 
in the middle with a single fovea. Elytra broadly ovate, very convex, 
deeply punctured, the punctures varying greatly in size and depth, and 
arranged, somewhat irregularly and at unequal distances, in ten longitu- 


96 Mr. J. 8. Baly on siw new species 


dinal rows on each elytron,—the first row abbreviated, the others ap- 
proximating in pairs; on the outer border is also a single row of finer 
punctures ; interspaces shining, slightly swollen, impressed with a few 
fine scattered punctures; the strie here and there deeply sulcate. 
Body beneath subremotely punctured. 

Hab. Northern China. 


4. Chrysomela separata. 


C. oblonga, convexa, nitido-cuprea; thorace transverso, lateribus rotun- 
datis, subincrassatis, profunde rugoso-punctatis, disco sparse hic illic 
fortiter punctato; elytris profunde punctatis, punctis in striis inter- 
ruptis dispositis.—Longe. 4 lin. 

Oblong, convex, shining cupreous. Head vaguely punctured; an- 
tenn scarcely half the length of the body, robust, nigro-eeneous. 
Thorax twice broader than long; sides slightly ampliate-rotundate, 
narrowed in front: disk sparingly covered with large, deep, irregularly 
crowded punctures; sides incrassate, deeply and coarsely rugose-punctate, 
their inner edge bounded by a longitudinal depression. Scutellum 
smooth, impunctate. Elytra subovate, convex, deeply porose-punctate ; 
punctures large, somewhat irregularly arranged in interrupted longitu- 
dinal rows (about ten in each elytron), which indistinctly approximate 
in pairs; interspaces smooth, slightly swollen, impunctate. Body 
beneath shining cupreous, finely but remotely punctured; legs nigro- 
ceneous. 

Hab. Northern India. 


At once distinguished from the preceding species (to which it is 
otherwise closely allied) by its narrower and less convex form, and 
by the rugose lateral border of its thorax. , 


5. Chrysomela Bowringi. 


C. oblonga, convexa, nigro-znea, nitida ; thorace disco fortiter- et irregu- 
lariter-, lateribus rugoso-punctato; scutello elytrisque rufo-testaceis, 
geneo vix micantibus, his subcrebre subseriatim punctatis; abdomine 
ad apicem plus minusve rufo-testaceo.—Long. 4 lin. 

Oblong, convex, nigro-seneous, nitidous; scutellum and elytra rufo- 
testaceous, with a faint metallic reflexion. Head punctured; antennze 
half the length of the body, slightly incrassate towards their apex. 
Thorax nearly twice broader than long; sides slightly rounded, narrowed 
towards their apex, sometimes notched at the base, anterior angles sub- 
acute: disk irregularly punctured ; sides moderately incrassate, coarsely 
rugose, bounded within by a longitudinal depression. Elytra four 
times the length of the thorax, oblong-ovate, sides slightly oval, apex 
regularly rounded; above moderately convex, surface covered with 
numerous irregular rows of deeply impressed but not very large punc- 


of Chrysomela from the East. 97 


tures; interspaces smooth, impunctate. Body beneath dark metallic- 
green, the posterior border of the three or four apical segments, and in 
some specimens the entire apex of the abdomen, rufo-testaceous. 

Hab. Hong Kong. Collected by J. Bowring, Esq. 


This pretty insect ought to stand near C. grossa and its congeners. 


6. Chrysomela cingulata. 

C. elongato-ovata, convexa, nigro-gnea, nitida, supra obscure cuprea ; 
thorace lateribus incrassatis, intra marginem sulcatis et profunde punc- 
tatis, disco tenuiter subcrebre punctato; elytris fulvo-rufo marginatis, 
punctato-striatis, striis bifariam dispositis ; antennarum articulo ultimo 
penultimo fere duplo longiore, oblongo-ovyato, apice angustato.—Long. 
3-4 lin. 

Elongate-ovate, convex, nigro-geneous or obscure cupreous, nitidous ; 
body above obscure cupreous. Head finely but distinctly punctured, 
puncturing scattered on the forehead, rather more crowded on the lower 
portion of the face; antennge nigro-czeruleous, slender, rather shorter 
than half the body, their apical joint oblong-ovate, its apex subacumi- 
nate; three basal joints more or less fulvous beneath. Thorax twice 
broader than long; sides nearly straight and parallel behind the middle, 
rotundate-angustate in front, more quickly narrowed at the apex ; upper 
surface with its lateral borders thickened, and bounded internally with 
a broad shallow longitudinal depression, more distinct at the base, its 
surface covered with large, deeply impressed, irregularly confluent, 
variolose punctures; disk, together with the thickened margin, sub- 
remotely covered with distinct but fine punctures. Scutellum smooth, 
shining, semi-ovate. Elytra slightly broader than the thorax, five times 
its length; sides subparallel, their outer margin bordered with fulvo- 
rufous: each elytron with eleven rows of distinct, deeply impressed 
punctures; the first abbreviated; the second running parallel to the 
suture; the eleventh finer, and placed on the extreme edge of the rufous 
border ; the eight others forming four double rows of punctures, which 
are placed at nearly equal distances on the disk; interspaces vaguely 
and distantly reticulate-strigose, minutely and subremotely punctured. 
Beneath shining, distantly punctured; legs covered with subremote 
deep punctures. 

Hab. Northern India. 


Nearly allied to Chrysomela marginata, but easily separated from 
that species by its larger size, finer punctation, and, above all, by the 
different form and greater length of the terminal joint of its antenne, 
which themselves are also more slender than in C. marginata. In 
the present insect the last joint is more slender and nearly twice the 
length of the penultimate, whilst in the other species it is broader, 
shorter in relation to the penultimate, more regularly ovate, with its 
upper edge towards the apex oblique.

Calonecrus rufipes. 
C. rufo-flava; oculis elytrisque nigris. 
Hab. Borneo. 
Entirely reddish-yellow, except the eyes and elytra, which are black ; 
head and prothorax finely, elytra more coarsely punctured ; sides of the 
latter, pygidium, femora and tibisze pubescent. Length 3 lines. 


Proportionally a more slender form than C. Wallace’, Thoms., and 
altogether less robust, with the antennee and legs reddish-yellow, 
and not black as in that species.

Prostomis morsitans. (P1. V. fig. 6.) 


P. oblongus, testaceus vel piceo-testaceus ; prothorace transverso ; elytris 
punctato-striatis. 
Hab. India (Darjeeling). 
Larger and proportionally broader than P. mandibularis, the pro- 
thorax transverse, the antenne shorter, &c. Length 4 lines. 


In the only two specimens which I have scen (in the British 
Museum), one is very much darker than the other. Mr. Bakewell 
has another very distinct species from Melbourne. 


Rayssorera [Cucujidee ]. 


Head small, slightly exserted, narrowed anteriorly. Antennee of moderate 
length, the first joint thick, abruptly contracted at its base, the rest 
more or less ovato-triangular, the last three stouter, forming a loose 
oblong club. Eyes transverse, rather prominent. Mandibles bidentate at 
the apex. Labrum long, narrow, rounded anteriorly. Palpi claviform, the 
last joint broadly ovate, obliquely truncate, the maxillary much larger 
than the labial, and widely separated at their origin. Mentum subqua- 
drate, not larger than the labium, which is transverse and emarginate 
anteriorly ; external maxillary lobe broad, strongly ciliated, imner very 
narrow. Prothorax subcordate, scarcely sinuated in front. Elytra 
much broader than the prothorax, parallel, slightly depressed. Legs

small; anterior cox transverse, scarcely approximate ; tibiee bicalca- 
rate ; tarsi five-jointed, slender, short, hairy beneath. 


If rightly referred to the Cucujide, the position of this genus will 
be near Silvanus, which it approaches in habit and in its clavate 
antenne. 


Rhyssopera areolata, (Pl. VIL. fig. 4.) 


R. fusea, sparse flavo-pubescens; prothoracis basi latiuscula; elytris 
areolatis. 
Hab. Tasmania. 

Opake umber-brown, with a sparse yellowish or almost golden pubes- 
cence, especially on the head and prothorax, the latter about as broad 
as long, rounded at the side, produced into a short acute angle ante- 
riorly and slightly contracted behind, with four tubercles on its disc ; 
scutellum transverse ; elytra with their external margins serrated, each 
with three rows of coarsely punctured hexagonal nearly equal cells, the 
walls of which are formed by narrow raised lines; labrum, palpi, and 
legs ferruginous. Length 4 lines. 


Rhyssopera illota. (Pl. VII. fig. 4, trophi only.) 


R, fusca, sparse griseo-pubescens ; prothorace longiore, basi angustata ; 
elytris subareolatis. 
Hab, Australia (Melbourne). 
Like the last, but the prothorax is longer and much narrower poste- 
riorly, the lines bounding the areole and punctures less marked, and 
the pubescence of a greyer hue. 


Griaanta [ Trogositidee ]. 


Head small, rounded and dilated below the eyes, emarginate in front. 
The labrum entire. Antenne short, eleven-jointed, the last three form- 
ing a subunilateral, compressed club. Eyes round, prominent. Mandi- 
bles entire at the apex, toothed in the middle. Palpi robust, with the 
terminal joint subcylindrical ; maxillary lobes finely toothed, the inner 
narrow. Labium quadrate, slightly fringed. Mentum large, quadrate. 
Prothorax subquadrate, narrower anteriorly, broadly sulcated at the 
side, and slightly margined. Elytra scarcely broader than the pro- 
thorax, subdepressed, the sides nearly parallel. All the coxe distant ; 
femora broad, compressed ; tibize dilated below, terminating in a series 
of small teeth; tarsi slender, slightly ciliated beneath, the basal joint 
minute, the second as long or longer than the third and fourth together ; 
claws toothed at the base. Prosternum rounded behind; mesosternum 
depressed. * 


The Trogositide do not appear to have any very definite characters, 
if we except the minuteness of the first tarsal joint, and include 
genera varying very much in their form. Of the four subfamilies

Gleania ulomoides. (Pl. VIII. fig. 9.) 


G. fusco-picea, subleevigata; prothorace antice excavato; elytris seriatim 
punctatis. 


Hab. Brazil (Rio). 

Rather depressed, dark pitchy-brown, nearly smooth and shining ; 
head and prothorax minutely punctured, the latter with along V-shaped 
excavation in front, with the side broadly and deeply grooved, the 
eroove bounded internally by a gradually elevated ridge, which ante- 
riorly forms a well-marked angular process projecting slightly over the 
head, the external border of the groove formed by a narrow uniform 
line, parallel to, and very slightly removed from the margin of the pro- 
thorax; scutellum very transverse ; elytra with about seven rows of 
minute punctures on each, the shoulder with a short broad ridge gra- 
dually passing into the disc posteriorly ; anterior and intermediate 
tibiee rounded and denticulate externally at the extremity, with the 
posterior strongly spurred internally ; body beneath scarcely punc- 
tured. Length 3 lines.

Hab. Australia (Melbourne). 

Oblong, pitchy-brown, rather sparingly covered above with short, 
round, whitish scales, varied with black; head and prothorax with 
large, shallow, crowded punctures with a few white scales, which are 
more closely arranged on the sides of the latter ; scutellum triangular ; 
elytra becoming gradually broader behind for about two-thirds of their 
length, with three elevated lines on each, a broad stripe of whitish 
scales extending along the suture, giving off a transverse branch at the 
base, another rather below the middle, and expanding again at the 
apex; lip, palpi, antennze, legs, and borders of the prothorax, and 
elytra beneath ferruginous. Length 4 lines. 


Leperina cirrosa. 
L. oblonga, picea, supra albo nigroque squamosa, fasciculisque elongatis

Hab. Australia (Moreton Bay). 
Oblong, pitchy-brown, covered above with white, and more or less 
lengthened scales, occasionally collected into fascicles, and varied 
with black; head and prothorax remotely and deeply punctured, with

small and mostly white scales, except on the sides of the latter, where 
they are drawn out into long, linear, curved laminz, on each side a long 
fascicle of whitish hairs mixed with black, and nearly meeting on the 
median line anteriorly ; scutellum triangular, with a tuft of erect white 
scales ; elytra parallel, the scales towards the suture principally white, 
but more or less black at the side, long and filiform at the base, and 
spatulate on the exterior margins, a fascicle of long, erect black scales 
on the middle of each near the suture, and posteriorly another of mixed 
black and white scales; body beneath, legs, antenne, and lip dark 
brown or nearly black. Length 4 lines. 


In this curious species, the lines on the elytra are nearly covered 
by the longer and more densely set scales. In all the Australian 
and New Zealand Leperine which I have examined, I have never 
noticed any other than simple, undivided eyes. 


Leperina lacera. 


L. oblonga, picea, supra nigro-squamosa, albo varia, fasciculisque brevibus

Hab. Australia (Melbourne). 

Oblong, pitchy-brown, partially covered with short black scales, and 
sparingly varied with white ; head coarsely punctured, with two black 
fascicles between the eyes; prothorax with a smooth elevated median 
line, the sides strongly and deeply punctured, above four short black 
fascicles anteriorly, the margins densely covered with long, white, ap- 
pressed scales; scutellum triangular; elytra rounded at the sides, the 
scales almost entirely black, spatulate at the margins, with a single 
short black fascicle on each shoulder ; body beneath, legs, and antenne 
dark ferruginous. Length 4} lines.

Bitoma serricollis. 


B. depressa, fusca; prothorace punctato utrinque bicostato, lateribus ser-

Hab, Australia (Melbourne). 

Depressed, dark brown; head coarsely punctured, grooved at the side 
below the eyes, and somewhat three-lobed anteriorly ; prothorax trans- 
versely subquadrate, coarsely punctured, with two costw on each side, 
the exterior crenate, continuous with its fellow in front, the sides strongly 
serrulate, the anterior angle produced; elytra a little wider than the 
prothorax, with five narrow costze on each, the intervals transversely 
plicate from a double row of deeply impressed punctures ; antennee and 
legs rusty-red ; body beneath coarsely punctured. Length 2 lines. 


A little broader and more depressed than Bitoma crenata; but, as 
far as external characters go, there can be no doubt as to its genus.

utrinque bicostato, costa interiori postice duplicata, antice emarginato, 
lateribus crenulatis. 

Hab. Moluccas (Batchian). 

Broad and depressed, dark brown varied with reddish-yellow ; head 
punctured, a little concave on each side below the eyes ; prothorax trans- 
verse, finely granulated, broadest at the base, rounded and dilated 
at the sides and irregularly crenate, deeply emarginate in front, the disc 
with two coste on each side, the interior approximating and forming a 
short canal open towards the head and a loop posteriorly ; elytra not 
wider than the prothorax, with five crenulated coste on each, the 
intervals with a double row of deeply impressed punctures, a yellowish 
spot on the shoulder, another near the apex, between these three others, 
which, with their fellows, form an indistinct ring; legs pale yellowish- 
brown; body beneath dark brown. Length 23 lines. 


A broader species than the last, with the prothorax especially di- 
lated at the sides and deeply emarginate anteriorly ; hereafter it may 
be found necessary to separate it generically from Bitoma. 


Bitoma jejuna. 


B. angusta, rufo-brunnea; prothorace quadrato, granulato, utrinque tri- 
costato, costa interna antica abbreviata. 
Hab, Brazil (Rio). 

Narrow, slightly depressed, reddish-brown, the elytra paler; head 
granulated, principally between the eyes; prothorax quadrate, equal in 
length and breadth, with three cost ‘on each side, the inner very short 
and confined to the anterior part, the interstices strongly granulated, 
the margins crenulated ; scutellum subquadrate ; elytra with five costze 
on each, the interstices with two rows of rather shallow punctures; 
legs and antennee ferruginous ; body beneath dark brown, the abdomen

Hab. Natal. 

Moderately convex, dark brown, more or less clouded with a lighter 
shade, or even inclining to grey; head with a line of four tubercles 
between the eyes, the antennary orbit large, a semicircular impression 
above the epistome ; mentum large, quadrate ; labium transverse, entire, 
ciliated in front; prothorax very transverse, wider than the elytra, 
the sides strongly dilated and margined with a double series of equal 
serriform tubercles, and deeply sinuated in front for the reception of the 
head, the disc with a row of five tubercles on each side the central 
line, the anterior pair accompanied by two others placed on the edge of 
the prothorax; scutellum small, quadrate ; elytra seriato-punctate, 
slightly gibbous at the base, so as to be above the line of the prothorax, 
a row of small tubercles along the side, above this another of three 
oblong tubercles, followed by a third row which is incomplete in the 
middle, and lastly close to the suture is a line of smaller tubercles run- 
ning, with a slight interruption posteriorly, to the apex,—the sides less 
strongly dilated than in the prothorax, but edged with a double row of 
serriform tubercles of the same size (in some specimens there isa lighter 
shade posteriorly, forming a band-like mark) ; antenne, palpi, and eyes 
ferruginous, with a paler pubescence ; body beneath dark brown, 
covered with small tubercles. Length 3 lines. 


Rechodes fallax. 


R. fere convexus, fuscescens ; elytris antice subdepressis, tuberculis ob- 
longis instructis. 
Hab. Natal. 

Closely allied to the former, but is smaller, less convex, the elytra 
narrower, and their base being depressed, they are on the same line 
with the prothorax ; the disposition of the tubercles is almost precisely 
the same, except perhaps that they may be a trifle less marked ; the 
colour in both species is somewhat variable. Length 2} lines.

tather depressed, dark brown, tomentose; sides of the prothorax, 
and a large patch on the dise of the elytra, which, commencing at the 
base, is contracted in the middle and again expanded behind, and a 
smaller spot at the apex, greyish-white ; disposition of the tubercles 
(which are all more or less conical) nearly as in the last; antenne, 
palpi, and legs dull reddish-brown ; under surface dark brown, covered 
with numerous small tubercles, and but slightly pubescent. Length

The few characters which Erichson has given of Fechodes accord 
perfectly well with the insects described above, except that the last 
joint of the maxillary palpi is scarcely securiform, although very 
broad and truncate. Rechodes is closely allied to Ulonotus and En- 
dophlaeus. To the former of these genera, M. Lacordaire refers, and 
I think correctly, Bolitophagus antarcticus, White ; and I would also 
refer to it Asida serricollis, Hope. The genus Pristoderus of the 
latter author, founded on the Dermestes scaber, Fab., is probably 
identical with Ulonotus. 


Distapuyta [ Colydiide }. 


Head small, transverse, scarcely visible from above, slightly dilated below 
the eyes, with a broad antennary groove beneath. Antenne short, stout, 
11-jointed, the two basal incrassated, the third longer than the rest, 
which are very transverse, the last two forming a short compressed 
club. Eyes large, round. Mandibles bidentate at the apex. Palpi 
robust, the terminal joint of the maxillary elongate, subcylindric, of 
the labial obovate; maxillary lobes narrow, ciliated. Labium very 
small, subcordate, fringed with long cilia. Mentum large, narrowed 
in front, rounded and dilated at the sides. Prothorax nearly qua- 
drate, very irregular anteriorly, the margin granulate and setose. 
Elytra elongate, subcylindrical. Legs short; coxze not contiguous ; 
tibie gradually enlarging at the extremity, terminated by two small 
spurs, and bordered externally with a row of stiff sete ; tarsi with the 
three basal joints short, hairy below. Prosternum rounded posteriorly, 
the mesosternum depressed. 


Judging from the position which Erichson has assigned to his 
genus Phleonemus, this must be a near ally, although it cannot be 
by any means likened to Colobicus.

brown), strongly and deeply punctured, the intervals having the 
appearance of granulations, and being furnished here and there with 
short stiff yellowish hairs or sete; head deeply and semicircularly 
grooved between the eyes; prothorax narrowing slightly behind, the 
sides strongly granulated in a double row which is divided from the 
eranulations of the disc by a smooth line, anteriorly two large oblong 
lobes overhanging the head, separated from each other by a narrow 
groove, but posteriorly from the rest of the prothorax by a broad deep 
hollow, which extends beneath them; scutellum small, triangular; 
elytra with about eleven rows of large deep punctures; legs reddish- 
ferruginous, with stiff scattered hairs; antenne short, not longer than 
the breadth of the head, dark brown, slightly setose; body beneath 
roughly punctured. Length 23 lines. 


Acroris { Colydiidee }. 


Burmeister, Gen. Ins. no. 25. 


Acropis Fryi. 

A. rufo-picea, fulvescenti-hirta ; elytris subseriatim tuberculatis, tuberculis 
setiferis, fasciculis sextis nigris in medio obsitis; pedibus ferrugineis « 
nigro yariis. 

Hab. Brazil (Rio). 

Reddish-pitchy, rather sparingly clothed with short, scale-like, grey- 
ish-yellow or almost golden hairs; head and prothorax with a few grey- 
ish setee, the latter with about five dark spots on its disc; scutellum 
rounded behind, closely covered with white hairs; elytra uneven, 
with several small granular tubercles, ranged in more or less inter- 
rupted lines, each tubercle bearing at its apex a black erect rigid seta, 
in the centre six dense fascicles of stiff black hairs, the first and third 
of these nearer the suture than the second, an oblique stripe (composed 
of more closely set hairs) below each shoulder, and towards the apex 
another oblique patch of pure white hairs (composed, however, of two 
distinct spots); legs dark ferruginous, with scattered grey hairs, the 
femora varied with black, the tibize with a black ring in the middle ; 
antenn and palpi pitchy-ferruginous ; body beneath pitchy-brown with 
pale greyish hairs. Length 3 lines. 

This appears to differ from A. tubereulifera, Burm. (which, however, 

I have not seen) in its larger size, the black fascicles, the yellow, 

almost golden, tinge of its scale-like hairs, the absence of the shining 

chestnut colour of the apices of the tibia, knees, tarsi, &c. Bur- 
‘meister in his description of this genus has overlooked the basal joint 
of the antennz, and describes the second (last) joint of the club as 
composed really of two, soldered together, and in this he is followed 
by M. Lacordaire. I can find no trace of any such union, which, if 
it existed, would give twelve joints to the antenne, and not eleven, 


106 Mr. F. P. Pascoe on some new or little-known 


as is really the case, that is to say, with the addition of the basal 
one. A. Fryi and A. incensa were both taken by Mr. Fry at Rio. 


Acropis incensa. 


A, rufo-picea, fulvescenti-hirta; elytris subseriatim tuberculatis, tuber- 
culis setiferis, fasciculis plurimis fuscis in medio obsitis ; pedibus fer- 
rugineis. 

Hab, Brazil (Rio). 

Differs from the last in its much smaller size, comparatively narrower 
and longer elytra, in the more numerous tubercles, and brown fascicles 
of hairs, the almost unvarying hue of the pubescence, although near 
the shoulder and apex may be traced rather more densely set patches 
of hairs than elsewhere, and the more uniform colour of the legs. 
Length 12 line. 


Acropis aspera. (Pl. VI. fig. 1.) 


A, nigra; prothorace granulato; elytris seriatim tuberculatis, setiferis, 
macula alba pone humeros, postice fasciculo nigro indutis; tibiis tarsis- 
que ferrugineis. 

Hab. Brazil (Para). 

Black, very slightly shining, and nearly free from pubescence, except 
two small patches on the anterior margin of the prothorax, and a short 
oblique white stripe, which, however, may be resolved into three spots, 
below the shoulder; scutellum rounded behind, naked; prothorax 
covered with small flat granulations ; elytra with a large fascicle of 
black hairs on the lower third of each, the tubercles varying in size, but 
all furnished with a rigid black seta; antennee, tibize, and tarsi ferru- 
ginous. Length 2 lines. 


Leumis [Colydiide }. 


Head vertical, rounded in front, and prolonged at the sides into two 
short peduncles bearing the eyes. Antenne short, eleven-jointed, the 
last two forming a short ovate club. Prothorax short, very transverse, 
narrower behind, broader than the head anteriorly, the sides strongly 
denticulate. Elytra nearly regular above, not broader, except at the 
base, than the prothorax. Legs slender, first tarsal joint scarcely 
longer than the second. 


The other characters of this genus are the same as those of Acropis, 
to which, indeed, it is nearly allied; the form, however, of the pro- 
thorax, added to the apparent absence of asperities, and the peculiar 
scaly crust, which covers the whole of the upper surface, as if a layer 
of opake varnish had been applied to it, obviously prevent its union 
with that genus. The shortness of the first tarsal joint, being more 
of a comparative character, is, perhaps, of less importance.

Lemmis celatus. (Pl. VIII. fig. 3.) 


L. oblongus, grisescens, setis hamatis brevissimis obsitus ; antennis capite 
brevioribus. : 


Hab, Brazil (Rio). 

Oblong, brown ?, covered above as well as beneath with a scaly crust 
of a pale yellowish or greenish grey, with very short hooked hairs, 
particularly on the margins of the prothorax and elytra, curving for- 
wards on the former, and backwards on the latter; head (including the 
peduneles) narrower than the prothorax, this with seven well-marked 
but obtuse teeth on each side; scutellum punctiform; elytra a little 
wider posteriorly, each with three very slightly raised gibbosities near 
the suture, another at the shoulder, and externally towards the apex 
two or three more, but which are considerably less prominent ; antennz 


pitchy, shorter than half the length of the head; legs pitchy; eyes 
dark brown. Length 14 line. 


In one of the two specimens now before me, the hairs are scarcely 
evident even on the margins, being, apparently, more enveloped by 
the scaly layer described above. In Mr. Fry’s collection. 


Ernetema [Colydiide ]. 


Head vertical, rounded anteriorly, and prolonged at the side into a short 
peduncle bearing the eye. Antennze as in Acropis, but more robust. 
Labium short, transverse, fringed with long hairs. Maxillary palpi 
robust, the terminal joint short, stout, obliquely truncate; the labial 
with the two basal joints small, the third large, broadiy subovate, 
slightly truncate. Mentum quadrate, very large. Prothorax as broad 
as the head, transverse, regular and convex above, narrowed anteriorly, 
the sides margined. Elytra oblong, nearly parallel, the surface smooth 
and regular. Legs rather slender; tibize not ciliated externally, ter- 
minated by two short spines. Prosternum produced behind. 


The above include the characters which, combined with the total 
absence of tubercles, chiefly separate this genus from Acropis.

E. oblonga, hirta, nigra, flavescenti-varia; prothoracis marginibus den- 
ticulatis, setosis. 
Hab. Brazil (Rio; Para). 

Oblong, closely covered above with short scale-like black hairs, many 
of which are curved backwards, more or less varied with pale yellowish 
or white; head not wider than the prothorax, a transverse depression in 
front below the peduncles; prothorax scarcely narrower than the elytra, 
except at the base, the margins denticulate, each denticulation with a 
short curved hair arising from its apex; scutellum very transverse ; 
elytra regular, punctate-striate, the striz rather remote, the patches of 


108 Mr. F. P. Pascoe on some new or little-known 


yellowish hairs more conspicuous on the head and prothorax, but in- 
definite as to outline and varying apparently in different individuals ; 
body beneath black; legs with a few scattered hairs only. Length 
2 lines.

D. elongato-ovatus, fuscus ; prothorace elytrisque costatis, costis ferru- 
gineo-hirtis. 
Hab. New Guinea (Dorey). 
Elongate-ovate, dark brown, with stout, stiff, caleeeat pale rusty hairs 

(or scales), which are chiefly confined to cost and other elevations on 
the upper surface; head small, partially retracted in repose ; prothorax 
with two waved grooves on each side, the outer smallest, and fringed 
with stiff hairs; scutellum scarcely visible; elytra punctato-sulcate, 
the coste between them closely covered with stiff hairs ; body beneath 
coarsely punctured, with a setaceous hair in the centre of each ; palpi 
ferruginous. Length 5 lines. 

Larger and stouter in proportion in all its parts than the Cey- 
lonese D. porosus, but otherwise very closely allied. 

I am unable, at present, to give any oral details of this curious 
genus, which Mr. Walker has only very briefly characterized, at the 
same time associating it with the Hydrophilde ; it is, however, an 
undoubted Colydian, and evidently nearly allied to Emmagleus of 
M. Léon Fairmaire. The large primo-abdominal segment and distant 
posterior coxze suggest also an affinity with Bothrideres and Derata- 
phrus ; but its head, vestiture, and habit altogether, point to a distinct 
subfamily. It may be mentioned that all the coxe are widely 
apart; the femora canaliculate beneath for the reception-of the tibie, 
which are fringed with stiff hairs externally, and the anterior ter- 
minated by two spines, the inner of which is much longer and curved, 
whilst the outer, under a strong lens, is seen to be tridentate; the 
mouth is almost entirely closed below by the prolonged mentum ? (as 
in Derataphrus), the small, pointed maxillary palpi protruding at the 
sides.

narrower behind, its anterior angles not produced although somewhat 
acute, a tubercle at the side, the dise very concave anteriorly, with a 
deeply impressed, interrupted ring in the centre, behind which is an oval 
depression terminating posteriorly in an elevated tubercle, which again 
has on each side a short but very deep and narrow groove; elytra elon- 
gato-ovate, broader than the prothorax, deeply and irregularly striated, 
the interstices, except the two sutural on each side, with very strong, 
elevated, compressed tubercles, particularly at the base and inner row, 
becoming smaller and more conical externally,—each elytron, before the 
middle and on the outside of the second sutural stria, with two pellucid 
granules of an amber colour; body beneath with rather shallow, large, 
and somewhat remote punctures. Length 2} lines. 


The upper part of the labium in the figure is intended to repre- 
sent its cilia: as it stands, it only shows their position. 


Bothrideres latus. 


B. niger, latior; prothoracis angulis anticis productis, utrinque tricostatis. 
Hab, Brazil (Santarem). 

Wider than the last, black, opake; head rather coarsely and deeply 
punctured ; prothorax less coarsely punctured, rather wider than long, 
emarginate in front to receive the head, its anterior angles slightly 
produced, with three strong ribs on each side, the inner occupying 
the anterior half only, the outer terminating in the anterior angle, the 
disc largely impressed with a bilobed protuberance in the centre, and 
opening out behind into a deep channel, which is bounded on each side 
by an oblique protuberance ; elytra broader than the prothorax, strongly 
ribbed, the interstices with shallow, somewhat remote punctures, the 
ribs seven on each elytron, the external and the two sutural ones less 
marked than the others; antennz not longer than the breadth of the 
head ; palpi ferruginous; body beneath remotely punctured. Length

Hab. Brazil (Para). 

Black and slightly shining; head finely punctured, regular, a little 
convex in front ; prothorax oblongo-ovate, twice as long as the head, 
finely punctured, a very delicately elevated line along the middle, ter- 
minating posteriorly between two short linear impressions; scutellum 
very narrow; elytra nearly parallel, obtuse at the apex, each with five 
elevated costz having between them four broad deep grooves, the two

angle at the apex ; antenne and legs dark ferruginous, shining; body 
beneath shining, dark reddish-brown, with small oblong impressed spots. 
Length 4 lines. 


Anarmostes [ Colydiidee ]. 


Head subquadrate. Antenne short, eleven-jointed, the two basal incras- 
sated, the third longest, the rest gradually decreasing in length to the 
eighth, the last three forming an ovate, compressed, perfoliate club. 
Eyes large, round, slightly divided in front. Maxillary palpi sub- 
cylindric, the last joint obliquely truncate, the labial smaller, subacumi- 
nate. Prothorax elongate, narrower posteriorly, deeply sulcate, not con- 
tiguous to the elytra. Scutellum punctiform. Elytra elongate, nearly 
parallel, ribbed, wider than the prothorax. Legsshort; coxe not con- 
tiguous ; tibize spurred, somewhat dilated and more or less toothed 
externally near the apex; tarsi slender, hairy beneath, the basal joint 
subelongate. Prosternum prominent, keeled in the middle. Abdominal 
segments gradually diminishing in size. 

Allied to Sosylus, with which it also agrees in habit, but at once 
distinguished by its triarticulate club and suleate prothorax. I have 
not dissected the mouth of my specimen (which I owe to the kindness 
of Mr. Fry, by whom alone, I believe, it has been taken); but the 
mentum seems to be very small, and attached internally to the large 
subquadrate jugular plate, which M. Lacordaire has, apparently, 
denominated the “‘sows-menton” ; the point of insertion of the palpi 
is, however, not covered by it, but is more than usually obvious. 


Anarmostes sculptilis. (Pl. VIII. fig. 8.) 


A, elongatus, piceo-fuscus ; pedibus rufo-piceis. 
Hab. Brazil (Rio). : 

Elongate, dark pitchy-brown; head and prothorax covered with 
numerous impressed punctures, with a very short hair-like point in the 
centre of each, the latter with five deep longitudinal grooves; scutel- 
lum hollowed out in the middle ; elytra about three times the length 
of the prothorax, each with five strongly marked coste, the intervals 
with a double row of elongated punctures, giving the spaces between 
them a granulated appearance; antenne much shorter than the pro- 
thorax, yellowish-red ; legs dark pitchy-red ; tibise finely ciliated and 
armed externally at the base with three or four teeth; body beneath 
coarsely punctured, the abdominal segments with numerous fine, longi- 
tudinal, but more or less interrupted lines. Length 43 lines. 


Asprorera [ Colydiide]. 


Head rather narrow, depressed, slightly expanded at the sides over the 
antennee. Eyes large, round, with a deep antennary groove beneath. 
Antenne short, ten-jointed, the first two incrassated, the remainder

to the ninth more or less transverse, the tenth forming a round com- 
pressed club, Labrum small, entire. Palpi rather short, filiform, the 
last joint subcylindric. Mentum very transverse. Prothorax elon- 
gate, with nearly parallel, slightly margined sides, constricted a little 
at the base, produced anteriorly into a broad lobe overhanging the 
head. Elytra lengthened, parallel, very convex. Legs short; posterior 
coxe distant; femora strongly grooved beneath for the reception of 
the tibie; tibie enlarged at their extremity, without spurs, ciliated 
on their external margin; tarsi slender, the three basal joints very 
short. Prosternum produced. The first two abdominal segments larger 
than the others. 


Although the second abdominal segment is fully as large as the 
first, yet, as they exceed the remainder, this genus cannot be placed 
in any group in which the segments are equal; otherwise, as its 
posterior coxee are not contiguous, it might be associated with 
Pycnomerus, Apeistus, &e. In its scaly pubescence it differs from 
Bothrideres, Sosylus, and-all the genera of that group (and the cha- 
racter, as well as the absence of vestiture, like the sculpture, appear 
to me to be of importance in this family). The antenne, described 
as ten-jointed, may probably have eleven, the club being composed 
of two, soldered together. In the figure eleven joints are given, 
but the third should be united with the second. 


Asprotera inculta. (Pl. VI. fig. 3.) 


A. elongata, cylindrica, fusca, supra albido-squamulosa ; elytris seriatim

Elongate, cylindrical, dull brown, furnished above with stiff whitish 
scale-like sete; head coarsely punctured, with few scales; prothorax 
strongly and thickly punctured, with numerous scales between them, 
the anterior margin on each side obliquely grooved; scutellum very 
small; elytra very coarsely seriato-punctate, the alternate interstices 
with a more closely set row of scales than the intermediate ones; an- 
tennz not longer than the breadth of the head, reddish-brown ; legs 
reddish-brown ; body beneath dark brown, coarsely punctured. Length

PenTHeELtspa [Colydiide ]. 


Head small, slightly dilated below the eyes. Antenne short, stout, 
eleven-jointed, the last two forming a short ovate club. Eyes round. 
Mandibles bidentate at the apex. Maxillary palpi robust, the terminal 
joint broadly ovate, the labial smaller. Maxillary lobes short, ciliated, 
somewhat falcate, the inner narrower. Labium very transverse, 
rounded anteriorly, and finely ciliated. Mentum subquadrate, its an- 
terior angles rounded. Prothorax subquadrate, scarcely emarginate in 


112 Mr. F. P. Pascoe on some new or little-known 


front, with a narrow margin at the side. Elytra elongate, subparallel. 
Legs short; cox distant; tibize smooth externally, dilated at the 
extremity, and terminated by two or three spurs; tarsi stout, the first 
three joints subequal. Abdominal segments equal. Prosternum con- 
tinuous with the mesosternum. 


I believe this genus will be found to include that portion of 
Erichson’s Pyenomerus which is characterized by its eleven-jointed 
antenne. Dechomus, distinguished by having eight only, has been 
recently separated by M. Jacquelin du Val. The two European 
species, P. terebrans and P. inewspectus, with ten joints, will, there- 
fore, alone represent the true Pycnomeri. The species described 
below has very slightly impressed antennary grooves, a character 
which, among the Pycnomerine, does not appear to be of generic 
importance. 

Penthelispa porosa. 


P. elongata, subdepressa, rufo-picea; prothorace fortiter punctato ; ely- 
tris punctato-striatis. 
Hab. Brazil (Rio). 

Elongate, subdepressed, reddish-pitchy; head slightly convex in 
front, moderately punctured; prothorax longer than broad, a little 
narrowed posteriorly, covered with large and somewhat remote punc- 
tures; scutellum indistinct; elytra coarsely striato-punctate, the striz 
very narrow, with the punctures oblong; legs smooth, the internal 
border of the tibize towards the extremity, especially of the anterior, 
slightly spinulose; body beneath pitchy-brown, with large shallow 
punctures. Length 2 lines. 


Hyseris [ Colydiude ]}. 


Head short, transverse, immersed in the prothorax nearly to the eyes. 
Antenne of moderate length, arising beneath the lateral border of the 
head, moderately thick, ten-jointed, the joints ovate-elongate, setigerous, 
the first rather incrassated, the third longest, the tenth forming a pyri- 
form club. Eyes lateral, round, rather prominent. Mentum nearly 
quadrate. Palpi claviform, terminal joint of the maxillary much larger 
than the others, shortly ovate, truncate, of the labial oblong-ovate. 
Prothorax transverse, bisinuated in front, rounded and strongly ser- 
rated at the side, narrowed behind. Elytra much wider than the pro- 
thorax, broadly ovate, convex. Legs moderate; coxée distant ; femora 
robust; tibize fusiform ; tarsi short, the basal joint longer than the two 
following. Abdominal segments nearly equal. 


As the only specimen I have seen of this insect belongs to the 
British Museum, I am unable to give any account of its oral 
organs; but there can be no doubt that it is nearly allied to 
Apeistus, and it would therefore be interesting to know if it be

furnished with paraglosse, as in that genus. It is remarkable that 
the basal joint, which in Apeistus is very indistinct, and was con- 
sidered to be a mere knob (and the insect, therefore, trimerous) by 
Erichson, should be also in Hyberis so indented, that when viewed 
sideways it seems composed (at least in the intermediate tarsus) of 
two distinct joints; but the absence of any division beneath shows 
that it is not really so. 


Hyberis araneiformis. (Pl. VII. fig. 1.) 


H. fuscus, tuberculiferus, fulvo-setosus; antennis capite prothoraceque

Hab. Borneo. 

Broadly ovate, dark brown, opake, covered with small tubercles 
and short stiff fulvous hairs; head scarcely more than half the breadth 
of the prothorax, a thin patch of yellowish hairs in front of each eye; 
prothorax slightly convex, much broader than long, with two tufts of 
yellowish setose hairs on the disc, and six stout teeth on each side ; 
scutellum very indistinct ; elytra broad, convex, rounded at the side, 
the edges serrated, a small tuft of black hairs on each at the base, and 
a larger one common to both elytra behind and on the highest part of 
their convexity ; antennz about one-third the length of the whole 
insect, all the joints, except the last, furnished with three stiff sete 
arising in the middle of each, two anterior and one posterior; palpi 
ferruginous; legs rough, with short thick hairs, tarsi ferruginous ; eyes 
black; body beneath somewhat pitchy, coarsely punctured, Length

Prarax [ Colydiide }. ; 
Head short, transverse, rather widely dilated below the eyes, and deeply 
inserted in the prothorax. Antenne short, eleven-jointed, the two 
basal incrassated, and nearly concealed above, the third longest, the 
rest gradually diminishing in length and becoming transverse, the last 
two forming a compact ovate club. Eyes small, round. Mentum 
rounded at the sides and in front. Terminal joint of the maxillary 
palpi triangular. Prothorax transverse, largely dilated and rounded 
at the sides, narrowed posteriorly, the disc very convex and irregular. 

Elytra connate, much broader than the prothorax at the base, short 

and irregular. Legs moderate; all the cox distant ; femora robust; 

tibize fusiform, bordered externally with scale-like hairs; tarsi short, 
the basal joint longer than the second or third. Abdominal segments 
nearly equal. 

This genus, in habit like Ulonotus, is allied to the last (Hyberis), 
from which the eleven-jointed antenne and biarticulate club will at 
once distinguish it. The description of the mentum and palpi must be 
received with some hesitation, as they were examined in situ. The 
two specimens now before me are among those almost inexhaustible

captures of Mr. Fry at Rio, which perhaps, partly from their small 
size, and partly from the extremely limited area which many of the 
insects of that country affect, it is almost hopeless to expect can 
ever be obtained except by the most indefatigable and experienced 
collectors. The number of undescribed genera which are almost sure 
to be found in every extra-European collection that may be formed by 
an accomplished naturalist, should not be overlooked by those who 
are inclined to question the necessity of the multiplication of new 
names.

P. ovatus, fuscus, tuberculiferus, griseo-setosus; antennis capitis latitu-

Hab. Brazil (Rio). 

Ovate, dark brown, covered with short, stiff, scale-like hairs: head 
slightly concave above; prothorax somewhat bilobed anteriorly, its 
disc with four depressed tubercles; scutellum deeply set; elytra short, 
convex, with about ten tubercles on the disc, the posterior being the 
largest, the margins irregularly set with short stiff scales; antenne, 
palpi, and tarsi ferruginous, the former about equal in length to the 
width of the head. Length 1} line. 


Cuorires | Colydiidee |. 

Head transverse, much narrower than the prothorax and deeply inserted 
in it, its supra-antennary borders slightly produced. Eyes large, and 
very rough, from the facets being prolonged into short spines. Antenne 
short, slender, eleyen-jointed, the first and second slightly incrassated, 
the third longest, the remainder to the ninth gradually decreasing in 
length, the tenth and eleventh forming an abrupt ovate club. Maxillary 
lobes ciliated, the external subtriangular, the internal narrower. Palpi 
short, claviform ; the terminal joint of the maxillary ovate-cylindrical, 
of the labial ovate-oblong. Mentum subquadrate. Labium trans- 
verse, Ciliated anteriorly. Prothorax very transverse, narrowed and 
sinuated anteriorly, as broad as the elytra at the base. Elytra convex, 
short, the sides gradually rounded to the apex. Legs small; coxa, 
especially the posterior, very remote; femora compressed; tibie 
slightly enlarged at their extremity, ciliated externally, and terminated 
by two short spurs; tarsi short, slender, with long hairs beneath, the 
basal joint very distinct. Abdominal segments gradually decreasing 
in size. 

The widely separated posterior coxe narrow considerably the 
number of Colydian genera with which Chorites may be compared ; 
at the same time, although the first abdominal segment is in every 
way larger than the others, there is not the decided difference we 
see in Derataphrus, Sosylus, &c.; and if we exclude these genera,

we are reduced to Pycnomerus, Apeistus, &c. To none of these, 
however, is our insect closely related, the contiguity of the whole 
base of the elytra to the prothorax completely isolating it from all 
of them and their allies.

greyish scales, which are disposed in narrow rows on the elytra and 
form a regular fringe round their margins and the sides of the protho- 
rax ; antenne, palpi, and legs ferruginous, the tibiee with a black stripe 
externally and edged with a row of greyish scales; body beneath dull 
black, thickly punctured, the throat only covered with yellow scales. 
Length 2} lines. 

There is a second species? in my collection, also from Borneo ; 
but, except in its much smaller size (about 13 line long), and a few 
black scales being interspersed among the others, there is little to 
distinguish it.

Discoloma Fryi. (Pl. VII. fig. 2.) 


D. piceo-ferruginea vel testacea, pubescens ; elytris parce punctatis; an- 
tennis, palpis pedibusque dilutioribus. . 
Hab. Brazil (Rio). 

Pitchy-ferruginous, in some specimens testaceous, sparingly pubes- 
cent; head rather closely punctured, inserted in a deep emargination 
of the prothorax; prothorax very transverse, nearly twice as broad as 
long, very finely punctured, the margins gradually but strongly dilated, 
with its anterior angle rounded; scutellum small; elytra rather 
broader than long, and as wide as the prothorax at the base, the dise 
with several rather large, remote punctures, with a broad and strongly- 
marked margin at the sides; antennz, palpi, and legs pale ferruginous ; 
body beneath pitchy, with a few scattered hairs. Length 1} line. 


Although Erichson has characterized Discoloma in very few words, 
I cannot doubt that the insect described above is correctly referred 
to that genus, as indeed Mr. Fry had previously suggested to me; 
the only difficulty is, that Discoloma is said to have the basal joint 
of its antenne simple, or not enlarged, which is not the case in 
the present species. However, the habit of the typical form appears 
to agree with this, and is so remarkable—resembling some of the 
Nitidulide (Amphotis for example)—whilst the structure so nearly

116 Mr. F. P. Pascoe on some new or little-known 


aceords with Cerylon, in close proximity to which Erichson has 
placed the genus, that this discrepancy need not, for the present 
at least, necessitate the generic separation of the two insects. In 
addition to Erichson’s description, the following generic characters 
(most of them the same as in Cerylon) may be noticed in D. Pryt:— 
Eyes narrow, transverse, scarcely prominent; external maxillary 
lobe long and very slender, ciliated at the apex (inner lobe not 
seen) ; maxillary palpi short, the first joint very small, the second 
greatly enlarged, the third subcylindrical, the fourth minute, acicu- 
late; the labial palpi with the second joint enlarged, the third 
shortly conical; mandibles bidentate at their extremity; mentum 
small, quadrate; labium rounded anteriorly ; tarsi very short, the 
three basal joints oblique, and hairy beneath. 


GryptoLorts [ Colydudee }.

Glyptolopus histeroides. (Pl. VIII. fig. 5.) 


G. late ovatus, piceus ; prothorace elytrisque rugoso-costatis. 
Hab, Brazil (Rio). 

Broadly ovate, pitchy-black; head coarsely punctured, small, ver- 
tical, scarcely visible above, narrowed below the eyes; antenne twelve- 
jointed, the first large, incrassated, and uncovered at its insertion, the 
second short, not thicker than the third, the remainder becoming 
gradually stouter to the tenth and eleventh, the last small, closely 
enveloped in long silky hairs; prothorax semicircular, very convex, 
vaulted above and emarginate anteriorly, the centre with a broad longi- 
tudinal groove, and a stout interrupted costa on each side, the lateral 
margin strongly produced, the intervals coarsely punctured ; scutellum 
triangular ; elytra as broad as the prothorax at the base, but not con- 
tinuous with it above, the sides rounded and gradually decreasing pos- 
teriorly, with five strong rugose coste on each, the intervals coarsely 
punctato-granulate; all the cox distant, tibie fusiform, strongly 
fluted, not spurred, tarsi short; prosternum very strongly keeled, pro- 
duced behind, and received in a notch of the mesosternum ; first abdo- 
minal segment nearly as large as the rest together; body beneath 
coarsely punctured. Length 2 lines. 

The few characters which Erichson has given of this genus, its 
very peculiar habit (resembling an Onthophilus), combined with the 
acicular palpi of the Cerylonine, and its habitat of Brazil, would 
seem to leave no doubt that the insect described above is correctly 
referred to Glyptolopus. The antenne, however, are certainly 
twelve-jointed, while Glyptolopus is said to have only eleven. Has

the little terminal joint been overlooked ; and the ninth, which is 
nearly as large as the eleventh, been regarded as one of the three 
forming the club? 


Aurimsia [{ Mycetophagidee |. 


Head deeply inserted in the prothorax, triangular, slightly dilated below the 
eyes. Antenne longer than the prothorax, eleven-jointed, the last three 
forming an oblong perfoliate club. Eyes large, round, very prominent, 
rugose. Maxillary palpi with the second and third joints thickest, the 
terminal obconic, truncate; the labial short, triangular, approximate. 
Maxillary lobes narrow, nearly equal. Prothorax transverse, narrower 
and slightly emarginate in front, rounded at the side, the base bisinu- 
ated. Elytra slightly convex, margined, the base closely applied to 
the prothorax, but enlarging behind the shoulder, then rounded to the 
apex. Legs moderate; coxee distant; tibiz fringed externally, en- 
larging towards the extremity, and terminated by four or five short 
spines; tarsi slender, hairy beneath, four-jointed, the anterior with the 
penultimate very indistinct (male only ?). 

Resembles Mycetophagus in outline, but with a triarticulate club, 
and large round, very rugose and prominent eyes. 


Althesia pilosa. (Pl. VI. fig. 4.) 
A, piceo-brunnea, griseo-pubescens, pilosa; corpore infra pedibusque 
rufo-brunneis. 
Hab. New Guinea (Dorey). 

Pitchy-brown, covered with a close greyish pubescence combined 
with numerous soft, slender hairs; head scarcely half the breadth of the 
prothorax, sparingly punctured ; prothorax with three grooves on each 
side, the inner two connected by a deep transverse one at the base; 
elytra slightly convex, widest behind the shoulder, with a very narrow 
margin ; scutellum very small, triangular; body beneath and legs dark 
reddish-brown ; abdomen, femora and tibize with a fulvous pubescence. 
Length 3 lines. 


Arractocerws [ Lymexylonide }. 


Palis. de Beauvois, Magaz. Encycl. 1802 (sec. Lacord.). 


Atractocerus morio. (Pl. VI. fig. 5.) 
A, ater; elytris prothorace longioribus alis chalybeatis; profemoribus 
coxisque testaceis. 
Hab, Moluccas (Batchian). 

Black; head nearly round, thickly punctured, closely covered with 
short erect black hairs; antennze extending nearly to the end of the 
prothorax ; eyes large, widely separated above ; mandibles not project- 
ing; prothorax narrower than the head, quadrate, hairy, shining; 
scutellum subtriangular, obtuse behind; elytra closely punctured, 


118 Mr. F. P. Pascoe on some new or little-known 


pubescent, nearly as long as the head and prothorax together ; wings 
deep steel-blue, shining; abdomen black, slightly tinged with blue, 
with a very remote greyish pubescence ; legs black, anterior coxee and 
femora testaceous, the intermediate darker. Length 11 lines. 


Droptoma { Lampyridee |. 


Head exposed. yes very large, horizontally constricted, the upper 
portion smallest, the lower much larger, and completely contiguous. 
Antenne short, claviform, subapproximate, deeply set on each side of 
the narrow prolongation of the front, twelve-jointed, the first two in- 
crassated, the remainder forming an elongated club. Mandibles very 
slender, curved, not toothed. Palpi robust. Prothorax transverse, 
semicircular, not dilated at the sides. Scutellum rather large, tri- 
angular. Elytra as broad as the prothorax at the base, gradually rounded 
at the sides, narrow and flattened posteriorly. Winged. Legs mode- 
rate; intermediate coxze not approximate; tarsi slender, the fourth 
joint not bilobed. 


Although I do not hesitate to refer this most extraordinary insect 
to the Lampyride, yet it must be confessed that it is a very aberrant 
form, and suggests no affinity with any Malacoderm genus that I am 
acquainted with, Its head (composed, at least externally, almost 
entirely of eyes, which are constricted in the middle like an hour- 
glass) is fully exposed; the narrow vertex descends behind the 
upper portion of the eye, and fills in the space behind and between 
the constriction, and is prolonged in front to terminate in the labrum, 
although, from the presence of numerous coarse hairs, the existence 
of this organ cannot be positively asserted. The antenne are very 
short, scarcely extending to the prothorax, and show no traces of 
being serrated. I am indebted for the only specimen I have seen 
to Dr. Ernest Adams, of University College, after whom I have 
named it. The abdomen of the specimen haying been cut away, 
apparently to facilitate (?) the mounting, the number of its segments 
cannot be ascertained: the abdomen itself, however, appears to have 
been very small; the metasternum must have exceeded it in length 
as well as in breadth. 


Dioptoma Adamsu. (Pl. V. fig. 2.) 


D. fusea, parce pilosa; scutello elytrisque pallide grisescentibus, his 
plaga elongata fusca humerali. 
Hab. India (Dacca). 
Dark brown, rather sparingly clothed with pale semi-erect hairs, 
especially on the prothorax ; head coarsely punctured, mandibles red- 
dish-brown, antenn and palpi pale yellowish; prothorax thickly and

coarsely punctured; scutellum and elytra very pale greyish, inclining 
to yellow, the latter irregularly punctured with several slightly-raised 
longitudinal lines and a dark-brown elongate patch at the shoulder ; 
body beneath and legs pale greyish. Length 5} lines. 


Corunapes [ Tenebrionide }. 


Head subquadrate, exserted, but not constricted behind. Eyes small, 
lateral, round. Antenne submoniliform, short, thick, very hairy, the 
basal joint longest, the rest to the tenth subequal, very transverse, 
the eleventh smaller, truncate. Labrum small, rounded anteriorly and 
ciliated. Mentum subquadrate, produced at the sides. Labium trans- 
verse, rounded in front. Palpi short, clavate, terminal joint ovate. 
Prothorax subquadrate, wider anteriorly. Elytra ovate, convex. Legs 
short; all the tarsal joints, except the last, very short. 


To this genus belongs the Tagenia leucospila of Mr. Hope; the 
head, however, not contracted behind into a neck, and other cha- 
racters show that it is very distinct from Tagenia [Stenosis]; at 
the same time it is difficult to point out a nearer ally. In this and 
the following genus the intermediate legs appear to be without 
trochanters. 


Cotulades fascicularis. (Pl. VII. fig. 5.) 


C. niger, rugoso-punctatus ; elytris obsolete albo-fasciculatis. 
Hab. Australia (Melbourne). 

Dull brownish-black ; head and prothorax covered with large, coarse, 
nearly confluent punctures, and sparingly furnished with stiff, decum- 
bent, scaly hairs; elytra coarsely striato-punctate, each with three 
indistinct ridges and with eight to ten short fascicles of brownish- 
white hairs, indeterminately arranged, but sometimes nearly wanting 
(from abrasion?); claws pale ferruginous; body beneath strongly 
punctured. Length 3 lines. 


Exascus [Tenebrionide ]. 


Head rather elongate, scarcely exserted. Eyes small, lateral, undivided. 
Antenne short, hairy, eleven-jointed, the first longest, the rest trans- 
verse and more or less equal, except that the last is smaller than the 
preceding one. Palpi moderate, filiform, the terminal joint ovate, sub- 
acuminate. Mentum transverse, the angles rounded. Labium small, 
transverse. Prothorax subquadrate, irregular, much broader than the 
head, projecting in front, and lobed posteriorly, slightly dilated and 
serrated at the sides. Scutellum very small, quadrate. Elytra nearly 
parallel, broader than the prothorax. Legs short; femora and tibize 
compressed, the latter ciliated externally ; tarsi very short and slender, 
the last joint nearly as long as the rest together. 


This genus is not very far removed from the last ; and, judging 


120 Mr. F. P. Pascoe on some new or little-known 


both from the figure and the description, I think that it is also alhed 
to Erichson’s Latometus*. 


Elascus crassicornis. (Pl. VIL. fig. 7.) 


E. subdepressus, fuscescenti-varius ; antennis medio abrupte incrassatis. 
Hab. Australia (Melbourne). 

Rather broadly depressed, covered with coarse, curly, dusky-brown 
hairs varied with paler or greyish markings; head and prothorax grey- 
ish-brown, the latter with four tubercles on its dise and the projecting 
anterior portion strongly bilobed; elytra bordered with hooked hairs, 
with three waved costze on each, terminating posteriorly in as many 
tubercles, between which and the apex is another and larger one, a 
small oblique stripe behind the shoulder and a broad band near the 
apex; antenne greyish-brown, the terminal half darker, with the third 
joint much thicker than the two preceding, the fourth and succeeding 
joints gradually diminishing in thickness; legs dark brown; body be- 
neath pitchy, with yellowish-brown scaly hairs. Length 3 lines. 


I have only seen two specimens, both of which were taken by 
Mr. Bakewell, at Melbourne, under the bark of trees composing a 
stock-yard fence. 


Elascus lunatus. (Pl. VII. fig. 8.) 


E. subangustatus, fuscus, nigro-varius; elytris albo-fasciatis. 
Hab. Australia (Melbourne). 

Rather narrow, slightly depressed, covered with coarse scaly hairs, 
which are yellowish-grey on the head, but considerably darker on the 
prothorax and elytra, or nearly black, the latter having three whitish 
bands (the two anterior crescent-shaped, but sometimes nearly coales- 
cing, the posterior straight); prothorax with four tubercles on its dise, 
the anterior projecting portion rather broadly bilobed, each lobe form- 
ing (so to speak) an additional tubercle ; elytra coarsely seriato-punc- 
tate, each with three costz, the inner nearly obsolete except at the 
base; antennze not abruptly thickened in the middle, yellowish varied 
with dark brown, especially the three terminal joints; legs ferruginous, 
more or less marked with dark brown; body beneath covered with 
ereyish-yellow scaly hairs. Length 23 lines. 


The post-prothoracic lobe is less developed in this species than in 
the former, or, in other words, it is broader and less abruptly de- 
fined. The two specimens (also captured by Mr. Bakewell) now 
before me differ considerably in depth of colour and amount of white 
on the elytra; but in this, as in other instances, the pattern is the 
same.

Docaxts [Tenebrionids |. 

Head rounded, exserted, the antennary orbit nearly dividing the eye. 
Antenne short, covered with numerous small flattish hairs, the first 
three joints longest, the rest transyerse, the tenth larger than the 
eleventh. Mandibles stout, bifid at the apex. Palpi robust, terminal joint 
of the maxillary short, stout, of the labial obconic, obtuse; external 
maxillary lobe short, triangular, fringed, the inner narrow, toothed. 
Mentum arising within the jugular plate. Prothorax subquadrate, 
scarcely wider than the head. Elytra ovate-oblong, broader than the 
prothorax. Legs short, the intermediate furnished with trochanters ; 
coxe not contiguous; tibize not spurred ; tarsi with all the joints ex- 
cept the last very short and fringed with spiny hairs. Prosternal pro- 
cess quadrate. Mesosternum depressed, 

The Tagenia funerosa of the Rev. F. W. Hope is, I think, refer- 
able to this genus; and, trusting solely to recollection of his type, 
now in the Taylor Institute at Oxford, it is very close to, if not 
identical with, my D. degener; but without certainty on this point, 
it is better to assume that they are distinct. The genus seems to 
be referable to the Scaurinz, and, so far as my knowledge of the 
group extends at present, it might follow Ammophorus. The struc- 
ture of the mouth, in reference to what I have called the “ jugular 
plate,” but which appears to be the ‘‘ sous-menton” of M. Lacordaire, 
is very similar, judging from that author’s description, to that of 
Nyctoporis, which genus immediately precedes Ammophorus. The 
larger penultimate joint of the antennz is suggestive in a shght 
degree of the club of many Colydian genera; ideed, there are so 
many points of resemblance between several of the Heteromera and 
the Colydiide, as to justify a doubt whether they may not be more 
than mere analogies. 


Docalis exoletus. (Pl. VIII. fig. 9.) 


D. oblongo-ovatus, fuscus; prothorace transyerso. 
Hab. Australia (Melbourne) ; Tasmania. 

Oblong-ovate, dark brown, everywhere covered, but not very closely, 
with semi-erect, stiff black scales (hairs), intermixed, especially on 
the head and prothorax, with rusty-white; prothorax slightly broader 
than long; scutellum rounded behind; elytra coarsely seriato-punctate, 
marked with several slightly elevated longitudinal lines, which are 
severally crested with a row of whitish scales; body beneath punctured, 
each puncture enclosing a short rusty hair. Length 2 to 3 lines. 


For my knowledge of this and the species of the two preceding 
genera, | am indebted to Robert Bakewell, Esq., who informs me 
that they, and many other insects as well, are found beneath the 


122 Mr. F. P. Pascoe on some new or little-known 


bark of logs which are piled one on another in the formation of 
stockades. Few of the many collectors in Australia appear to be 
aware of the novelties which a careful examination of such localities 
would afford them. 


Docalis degener. 
D. oblongo-ovatus, preecedenti angustior, niger; prothorace equali. 
Hab. Tasmania. 

Narrower and darker than the last, with the prothorax at least as 
long as it is broad, the scales whiter and less numerous and the punc- 
tures larger, and the longitudinal lines on the elytra more prominent. 
Length 2 lines, 


Spuarceris ['Tenebrionide |. 


Head small, transverse, abruptly contracted below the eyes. Antenne 
eleven-jointed, very short, gradually increasing in thickness from the 
third, which is longest, the second minute, the first inerassated. Eyes 
lateral, very small, round. Labrum narrow, not covering the man- 
dibles, which are bifid at the tip. Maxillary lobes narrow, the ter- 
minal joint of their palpi subsecuriform. Mentum subcordate, nar- 
rower behind. Labium bilobed and ciliated anteriorly; labial palpi 
long, the-terminal joint ovate, pointed. Prothorax short, transverse, 
narrower anteriorly, rounded at the sides. Elytra shortly ovate, very 
convex. Legs short, more or less covered with spinous hairs; tibie 
triangular, strongly spurred, the anterior sinuated externally; tarsi 
short, the basal joint longer than the second, Prosternum compressed, 
cariniform. 

Closely allied to Mr. White’s genus Cherodes (Voyage of the 
Erebus and Terror, Ins, p. 12. tab. 2. fig. 12), but differs essen- 
tially in the antenne, Chewrodes having (inter alia) a triarticulate 
club (see Pl. V. fig. 10); in both, however, they are eleven-jointed. 


Sphargeris physodes. (Pl. V. fig. 9.) 


S. testaceus, subnitidus, punctulatus; oculis mandibulisque nigris. 
Hab, Australia (Melbourne and Adelaide). 

Broadly ovate, very convex, smooth, shining, testaceous, closely and 
finely punctured; scutellum small, triangular; antennze about as long 
as half the breadth of the head; eyes and mandibles black; body be- 
neath darker, punctured, with short scattered hairs. Length 3 lines. 


Cuztyxuvs [Tenebrionide |. 


Head subtriangular, rounded posteriorly, larger than the prothorax, its 
supra-antennary borders forming a short, thick, elevated protuberance. 
Antenne moderately long, eleven-jointed, the first incrassated, the 


Genera and Species of Coleoptera. 123 


second minute, the third longest, the rest more or less moniliform and 
becoming gradually thicker upwards. Eyes lateral, small, round. 
Maxillary palpi strongly securiform, the labial very short and thick. 
Prothorax narrower than the head, much contracted behind. Scu- 
tellum none. Elytra connate, very convex, broadly elliptical. Legs 
moderate ; anterior coxze globose, not contiguous; tibiae unarmed, 
hairy at the base internally; tarsi short, thick, hairy beneath, the basal 
joimt longer than the second, the penultimate bilobed. Prosternum 
produced, rounded posteriorly, and remote from the mesosternum. 


An examination of the mouth might throw some light on the 
affinities of this very curious little insect ; but as the only specimen 
I haye seen belongs to the British Museum, and moreover is not in 
very good condition, this cannot be done at present. In habit it 
resembles the Anthicide, but the globose anterior coxe separate it 
from that family ; the bilobed tarsi, an unusual character amongst 
the Tenebrionide, suggest an analogy, or perhaps an affinity, with 
Phymatodes and Phobelius. It is one of the many important cap- 
tures of Mr. Bates in the valley of the Amazons; and as that gen- 
tleman is preparing a series of papers on some of the insects of his 
extensive collections, it is to be hoped that this and many other 
curious forms which he possesses will be at no distant date more 
amply illustrated. 


Cheetyllus anthicoides, (Pl. VI. fig. 8.) 


C. niger, nitidus ; prothorace elytrisque tuberculatis, tuberculis setigeris ; 
tarsis pallidioribus. 
Hab. Brazil (Ega). 

Black, shining; head coarsely punctured, with scattered, erect, 
setulose hairs, a semicircular groove between the antennary orbits; 
prothorax and elytra covered with large tubercular elevations, arranged 
in rows on the latter, each of which bears a long, erect, setose hair; 
tarsi and base of the tibize internally with pale silky hairs; labial and 
maxillary palpi at the base pale ferruginous ; antenne setigerous, ss 
long as the head and prothorax together. Length 2 lines. 


Dresaconra [Tenebrionide }. 


Head small, rather narrow and elongate below the eyes, deeply inserted 
in the prothorax. Eyes transverse, undivided. Antenne rather short, 
submoniliform, slightly hairy, the basal joint incrassated, the second 
very short, the third longest, the remainder gradually decreasing in 
length, but becoming broader and transverse, to the ninth and tenth, 
the eleventh subovate. Labrum rounded anteriorly. Maxillary palpi 
rather long, claviform, the last joint large, ovate, truncate; the labial 
very small; external maxillary lobe broad, strongly ciliated. Mentum 


124 Mr. F. P. Pascoe on some new or little-known 


quadrate. Labium very transverse. Prothorax narrower than the 
elytra, transverse, sinuated anteriorly, its surface regular. Elytra 
rather long, slightly rounded at the sides. Legs moderate ; tibize bi- 
calcarate, ciliated externally ; tarsi slender. 


Allied to Ulodes, Er., which differs in the followimg points. In 
Ulodes the head is short, not being prolonged below the eyes; the 
joints of the antennz are subequal and transverse, surrounded by a 
dense whorl of squamose hairs; the surface of the prothorax is very 
irregular; the elytra are short, and the body generally is covered 
with short crisp scales. To Ulodes I refer Bolitophagus Saphira, 
Newm., and Endophleus variicornis, Hope. My genus Byrsax (ante, 
p. 42) is also a member of this group of Tenebrionids (Bolitopha- 
ginee): it is true I cannot quite satisfy myself that it is hetero- 
merous, but I have no doubt a minute basal joint exists; and in 
other respects it appears to be congeneric with Diaperis horrida, Ol. 
(Asida horrida, Walk.). Trow cornutus, Fab., is also referable to 
Byrsax. 


Dipsaconia Bakewellii. (PI. VIL. fig. 6.) 


D. elliptico-ovata, pilosa, fulvo-brunnea ; elytris nigro-variegatis. 
Hab. Australia (Melbourne). 

Elliptic-ovate, brownish-fulvous, covered with short decumbent 
hairs, among which others longer, nearly erect and slightly curved, are 
interspersed ; prothorax nearly as wide as the elytra at the base; scu- 
tellum rather indistinct, subtriangular; elytra nearly parallel at the 
sides, rounded at the apex, striato-punctate, each with three costs, and 
varied with four or five dull-black band-like marks; antenne brown ; 
body beneath ferruginous-brown, very sparingly pubescent. Length 31 
lines. 

In this and the following species, both of which we owe to Mr. 
Bakewell’s researches, may be noticed, in certain lights, a glowing 
fiery-red tubercle at the bottom of each elytral puncture. 


Dipsaconia pyritosa. 
D. elongato-ovata, hirta, rufo-fusca ; prothorace elytrisque nigro-varie-. 
gatis. 
Hab, Australia (Melbourne). 

Elongate-ovate, reddish-brown, closely covered with short, thick, 
strongly hooked hairs ; prothorax narrower than the elytra at the base, 
the disc with a large irregular blackish patch; scutellum indistinct, 
subquadrate ; elytra rather broader behind, striato-punctate, marked 
with several irregular, dull brownish-black patches; antenne brown; 
body beneath and legs ferruginous-brown, sparingly pubescent. Length 
33 lines. : 


Genera and Species of Coleoptera. 125 


Tirmassa {'Tenebrionide }. 


Tlead small, exserted, its anterior border incrassated. Antenns stout, 
moderately long, the first and second joints scarcely thicker than the 
third, which is longer, the remainder to the eighth short, the last three 
forming an oblong, loose, compressed club. Eyes small, lateral, round. 
Epistome and labrum narrow, not covering the mandibles, the latter 
broadly emarginate. Mandibles bifid at the apex ; terminal joint of the 
palpi ovate, subacuminate, the second joint of the labial larger than 
the third ; maxillary lobes subequal, fringed. Mentum subquadrate. 
Labium rounded. Prothorax transversely subquadrate, narrower than 
the elytra, its margins dilated. Elytra large, convex, broadly ovate. 
Legs small; coxee not approximate, the anterior cylindrical, transverse ; 
tibize not spurred; tarsi pubescent beneath, the penultimate joint di- 
lated. Prosternum pointed behind; mesosternum depressed ; post- 
intercoxal process triangular. 


The majority of the characters of this genus point, as it appears 
to me, to the Diaperine, but the differently-formed tarsi and the 
disproportion between the prothorax and elytra forbid its union with 
that group. At the same time, the antennz come nearer those of 
Pentaphyllus “in plan” than any other heteromerous genus that I 
am acquainted with. It seems to be a common Rio insect. 


Tithassa corynomelas, (Pl. V. fig. 7.) 


T. testaceo-lutea, nitida, punctata; oculis, antennisque, ab articulo sexto, 
nigris. 
Hab. Brazil (Rio). 

Dark glossy testaceous, or luteous-brown, iregularly punctured 
above, with a few very fine and extremely scattered slender hairs ; 
eyes and last five joints of the antenn, including a portion of the 
sixth, which are also more hairy than the rest, black, Length 3 lines. 


Cuartorueca | Helopide |. 
(Dej.) Catal. des Coléopt. 


Head moderate, subquadrate. Eyes large, transverse, contiguous to the 
prothorax. Antenne short, claviform, the first joint nearly concealed 
above by the antennary orbits, the four or five terminal joints com- 
pressed and, except the last, more or less transverse. Labrum rounded 
anteriorly. Maxillary palpi with the last joint securiform, the labial 
ovate, truncate ; maxillary lobes short, strongly ciliated. Mentum 
subquadrate. Labium slightly expanded at the sides, entire and 
ciliated in front. Prothorax transverse, nearly as broad as the elytra at 
the base, rounded at the sides, scarcely emarginate anteriorly. Elytra 
elongate, their greatest breadth behind the shoulders, slightly curved 


126 Mr. F. P. Pascoe on some new or little-known 


at the sides. Legs rather slender; tarsi hairy beneath, the basal joint 
longer than the succeeding one. Prosternum pointed behind, with a 
narrow impression in the middle; mesosternum notched for the recep- 
tion of the prosternum ; post-intercoxal process pointed anteriorly. 


This unpublished genus of Dejean’s was placed by him nearly at 
the end of his Tenebrionites, an heterogeneous assemblage, including 
as it does Melandrya, Pytho, Pezodontus, Camaria, &c. With the 
last of these genera, however, and with its allies, Chariotheca must be

Omouirus | Helopidee }. 

Head transverse, vertical, sulcated in front. Antenne short, gradually 
increasing in thickness, the two basal joints small, the third longest, 
the fourth to the seventh obconical and decreasing in length, the last 
four submoniliform, compressed. Eyes transverse, partially divided in 
front. Labrum rounded anteriorly and ciliated. Mandibles bidentate 
at the apex. Maxillary palpi securiform; the labial approximate at 
the base, with the terminal joint triangular. Maxillary lobes small, the 
inner strongly hooked. Labium transverse. Mentum subtriangular, 
truncate at the base, carinated in the middle. Prothorax convex, rounded 
in front and at the sides, closely applied to the elytra, its parapleure 
distinct. Scutellum small, triangular. Elytra connate, ovate, convex. 
No wings. Legs stout; anterior coxe globular, not contiguous ; tibize 
straight, unarmed ; tarsi short, all the joints except the last dilated. 
Prosternum wedge-shaped, produced, with a deep central impression ; 
mesosternum notched for the reception of the prosternum. 


In characterizing @demutes (ante, p. 51), the semilunar, sulcated 
anterior portion of the head was described as the epistome, and M. 
Lacordaire appears to have done the same in his description of Sphe- 
rotus*, The real epistome, however, is inserted beneath the anterior 
border, and in Spherotus curvipes is completely hidden by it ; but, on 
the other hand, it is almost entirely exposed in another common 
species, Spherotus gravidus. In Omolipus (at least in the species 
described below ; for the character scarcely seems to be of generic 
value), the labrum, which is rather strongly developed, also appears 
to be inserted directly beneath the anterior border of the head, and 
the epistome is therefore not apparent. The nearest affinity of Omo- 
lipus is probably Misolampus, from which, among other characters, 
the presence of a very distinct seutellum will at once distinguish it. 
This genus is another exception to the absence of the hook on the 
internal maxillary lobe, a character which at one time was supposed 
to distinguish the Helopidz from the Tenebrionids. Another excep- 
tional character is the approximation of the base of the labial palpi, 
which are inserted in front of the broadly transverse, membranous 
lower lip.

3 Elytris convexis, angulis posticis cornutis. 
© Elytris deplanatis, angulis posticis muticis. 

Ovate, dark pitchy-brown, sparingly furnished above with pale yellow- 
ish-green scales; rostrum longer than the head, gibbous below the 
eyes, and separated from them by a semicircular depression, with a 
broad longitudinal furrow in the middle; prothorax shortly ovate, 
closely granulated, and covered with coarse deep punctures ; scutellum 
none ; elytra very short, perpendicularly bent down behind, roughly 
punctato-granulated, slightly convex in the male, with the posterior 
angle produced into a long flexible process, flat and depressed in the 
female, and without any prolongation ; legs moderate, furnished with 
stiff scattered hairs, the femora orange-red, except at the apex (in the 
female darker); antennz black, shorter than the body, slightly hairy ; 
body beneath pitchy, coarsely punctured. Length 383 lines (¢), 
3 lines (2). 

Brapstton [Cerambycide ]. 


Head short, scarcely convex in front. Eyes small, lateral, deeply emargi- 
nate. Antenne shorter than the body, sublinear, distant at the base, 
the first joint thickened, shorter than the third, which is longest, the 
fourth moderate, the remainder very short and subequal. Labrum small, 
slightly emarginate. Mandibles robust. Palpi stout, the terminal joint 
elongate-ovate, truncate. Mentum very short and transverse. Pro- 
thorax broader than long, narrower in front. Scutellum elongate, pro- 
duced anteriorly. Elytra ovate, broader than the prothorax at the base, 
elevated in the middle, and produced at the shoulder into a short, hooked, 
horizontal process. Legs moderate; cox distant; tarsi short, very 
slightly dilated. Prosternum received into a notch of the mesosternum. 


The scutellum of this genus is remarkable. It is not only un- 
usually narrow and somewhat hexagonal in form, but it is projected 
forwards on the prothorax, which is probably notched for its recep- 
tion, although this point cannot be ascertained without risk of in- 
jury to the specimen. Blapsilon must be placed near Tmesisternus.

The unusually large prothorax of this insect and its narrow,

the sides ashy-white; scutellum subquadrate, the apex white; elytra 
much wider than the thorax at the base, rather short, very slightly 
receding towards the apex, which is rounded, with considerably more 
than its basal half white, except at the shoulders and around the scu- 
tellum ashy-white, a few white spots also at the apex; legs rather short 
and robust, slightly tinged with ashy, the two basal joints of all the tarsi 
white; antenne nearly twice as long as the body, the base of the third,

Omosarotes [ Lamiidee ]. 

Head exserted, vertical, quadrate in front. Eyes very deeply divided, the 
two portions connected only by a narrow line. Antenne distant, 
robust, shorter than the body, pedunculate, and ciliated beneath, the 
first joint slightly incrassated, the third longest, the rest gradually 
decreasing in length. Epistome very short. Labrum small, transverse,

narrow, broadest at the base, convex. Legs moderate; tibize compressed, 
the anterior emarginate internally; tarsi very short, the basal joint trian- 
oular. Prosternum broad, rounded posteriorly; mesosternum sub-bilobed. 


This genus, with Scopadus, appears to enter into a small group 
of South American Longicorns, of which the Cerambyx sericeus of 
Perty may be considered as the type. ‘This is one of Mr. Bates’s 
rarest captures, he having never met with more than two specimens ; 
one is now in my collection, the other in his own.

is margined with a little white anteriorly, across their posterior third ; 
head narrower above the eyes, the peduncles bearing the antenn» 
rather distant, with a longitudinal groove between them; lateral tooth 
of the prothorax on the middle; a sharp carina half the length of the

X.—On certain Coleopterous Insects from the Cape of Good Hope. 
By T. Vernon Wottaston, M.A., F.LS. 


Havrye lately received’ a small, but very important, batch of 
Coleoptera from my friend Mr. Bewicke of Madeira, collected by 
himself during a short visit to the Cape of Good Hope in May and 
June last, I purpose describing a few of the smaller species which 
more immediately interest me,—either from their own singularity, 
or from their near relationship to certain forms with which I have 
long been acquainted in the Atlantic Islands. I may mention perhaps 
that Mr. Bewicke’s material, although got together very hastily, at 
the worst season of the year, and under peculiar disadvantages (he 
having omitted to take with him any nets, or other entomological 
apparatus, on his hurried departure from Funchal), contained about 
270 species; and since a large proportion of these belong to the 
smaller families, there are probably few collections which have been 
brought to this country from the Cape Colony that have afforded so 
fair a display of the minute Coleoptera of that almost inexhaustible 
region. In the present Paper I shall not attempt to characterize 
more than a very few of them, as I hope to reserve certain of the 
others for separate notices, according as leisure and opportunities 
may permit.

The present insect is peculiarly interesting, as being the second 
species hitherto detected of one of the most anomalous genera within 
the whole range of the Coleoptera. The genus was established by 
Mr. Westwood, in 1851, to contain a small (and then unique) beetle, 
discovered by myself in Madeira in 1848, and to which he gave the 
name of Cossyphodes Wollastonii. Subsequently it was ascertained, 
by Professor Heer of Zurich, during his residence in the island in 
1851, that the insect was an attendant upon ants, he having taken 
seven or eight examples of it within the nests of @eophthora pusilla 
around Funchal,—under which circumstances it has been since fre- 
quently captured by Mr. Bewicke, myself, Mr. E. Leacock and others : 
and I may add that I have taken it in similar positions in Teneriffe 
and Gomera, of the Canary Islands. Hence the detection, by Mr. 
Bewicke, of a new and very distinct species during his late visit to 
the Cape of Good Hope becomes exceedingly important, though more 
particularly in a geographical point of view,—as making it at least 
probable that Cossyphodes is an African, and not merely an Atlantic, 
form. In my Madeiran Catalogue, published in 1857, I called atten- 
tion to the fact, insisted on by Mr. Leacock, that the eyes of the 
Cossyphodes Wollastonii are not in reality quite obsolete (as inferred 
by Mr. Westwood, and subsequently endorsed by myself in the 
‘Insecta Maderensia’); but that they certainly exist, although in 
a very rudimentary state, immersed within the small oblique line or 
fovea with which either side of the head is furnished (on its upper 
surface) posteriorly. And it is satisfactory, therefore, to see, that 
this suggestion as to the peculiarity of the organs of sight is entirely 
confirmed in the species from the Cape of Good Hope,—in which the 
eyes are remarkably apparent, though to a certain extent buried 
within this lateral foveolet, or slit. In their minor details, the two 
species of Cossyphodes are very distinct, the unique C. Bewrckii dif- 
fering, not merely in its more apparent eyes and bituberculated 
head, but likewise in its rather broader, more elliptic, depressed and 
almost unkeeled body, alutaceous surface, and posteriorly-acute elytra. 
Its entire margin, also, especially behind, is more recurved ; its pro- 
thorax is shorter, and nearly free from any appearance of longitu- 
dinal cost (there being only the faintest possible indication of an 
obsolete line on either side); and the elytra have only three (instead 


from the Cape of Good Hope. 135 


of four) longitudinal costs down each,—and those extremely fine 
and delicate ones. 

Its habits appear to be the same as those of the Madeiran and 
Canarian C. Wollastonii, as I am informed by Mr. Bewicke that he 
captured it “in an ants’ nest on the Atlantic side of the promontory 
of the Cape, about three or four hundred feet above the sea.’ It 
would seem to be very scarce, for Mr. Bewicke states that he 
“searched diligently, but without effect, for more ;”—adding, 
«From the locality in which I took it, miles from even a road, 
amidst thick underwood and rocks, I should consider it as certainly 
a true native of the Cape.”

A pipnua imitatio. 


The two insects* on which the present genus is founded are so 
very close, in general aspect and structure, to the Madeiran and 
fanarian Hurops, that it was not until I had examined them mi- 
nutely that I could conceive it possible that they should perhaps be 
regarded as distinct; whilst even now I am anything but satisfied 
that they ought not rather to be treated as aberrant members of 


* Whether the Rhyzophagus capensis and rufulus of Dejean’s Catalogue, 
registered as natives of the Cape, be these two insects (which is not impossible, 
from their great external resemblance to Rhyzophagi), I cannot tell ; as, however, 
they are mere Catalogue-species, it fortunately is not of much importance to 
ascertain.

that Atlantic group. Their main difference consists in the structure 
of their tarsi, the first and second joints of which (instead of being 
simple) are very broad, and deeply bilobed,—except in the hinder - 
pair of the male sex, where only the basal one is thus developed. 
Moreover, as regards these hinder male feet, there may also be a 
difference in the actual nwmber of the articulations (as compared 
with those of Zurops) ; but unfortunately the structure is so obscure, 
even beneath the highest powers of the microscope, that I am unable 
to decide whether there are one or two minute joints concealed 
within the lobes of the basal one. If there should be but one, then 
the posterior male tarsi will be only trimerous, and therefore dimi- 
nished in the number of their joimts; but if two, they will be 
tetramerous (like the remainder of the feet in both sexes), their 
form only being altered,—#. e. the second articulation (which in the 
other feet is as large and cordate as the first) will be reduced to an 
excessively minute size, like the penultimate one in all the feet. At 
any rate, whether the number of the hinder tarsal joints of the male 
feet be the same or not, in Mimema and Europs {and I may add that 
it is nearly equally difficult to pronounce for certain whether they 
are trimerous or tetramerous even in the latter also], the form of the 
tarsi is unquestionably different,—the two largely-developed bilobed 
basal joints in all the feet of Mimema except the posterior ones of 
the male sex, where (whatever be the exact number of the following 
minute articulations) the basal one only is thus constituted, giving 
it a character which it is impossible to mistake. 

Moreover, this tarsal peculiarity is not altogether unaccompanied 
with minor differences (from Hurops) even in its oral organs; for in 
Mimema the antenne have their third joint a little longer than the 
fourth (thus making a slight approach to Rhyzophagus), and the 
two divisions of their club are more compact, or less separated from 
each other; also the outer maxillary lobe, although narrow like that 
of Europs, is not so aciculated, but almost palpiform,—appearing as 
though articulated at its base, and with its long apical portion sub- 
clavate. The ligula also of Mimema, although elongate and linear 
as in Hurops, is sharp and angular at its apex (between the palpi), 
instead of being obtusely rounded, and with broad elongate mem- 
branous internally ciliated paraglosse stretching out on either side 
from the anterior angles. The general aspect of both groups is that 
of Rhyzophagus; but, apart from the many other differences which 
will be gathered from the diagnoses, I may add that, whilst in the 
latter the numerical formula for the tarsal jomts is 5:5°5 and 5:5-4 
in the two sexes respectively, that for Mimema (and indeed for

Europs also) is either 4-4:4 and 4:4:3, or 4:4-4 in both sewes,—as the 
case may be. If properly distinct, however, so completely does our 
* present genus imitate its Atlantic representative, that I have thought 
the above generic title would not be altogether an inappropriate one. 


Mimema pallidum, n. sp. 


M. lineare, opacum, parce pubescens, rufo-testaceum; capite protho- 
raceque alutaceis, remote leviter punctatis, hoc quadrato ad latera 
minutissime subcrenulato; elytris leviter striato-punctatis, pallido- 
testaceis, concoloribus; pygidio rufescente ; antennis piceo-ferrugineis. 

Long. corp. lin. 13-1}. 

The larger size, broader outline, and pallid hue of the present 
Mimema, in conjunction with its more opake surface, ampler elytra, 
and consequently less exposed pygidium, will, apart from all other 
differences, immediately distinguish it from the following one. Al- 
though apparently not a Huphorbia-feeding insect like the Atlantic 
Europs, it would nevertheless seem to have something in common 
with the members of that genus, as regards its habits; for whilst 
Europs more particularly delights in the viscous, adhesive exudations 
in the interior of the rotten EHuphorbia-stems, Mr. Bewicke writes 
me word that the two species of Mimema “ dwell in the thick sticky 
matter at the bottom of the flowers of the common sugar-bush (a 
Protea),’”—which “ sugar-bush,” I am further informed by the Rev. 
R. T. Lowe, is probably a corruption of “ Sugarbosch” (the Dutch 
Zuykerbosch), and that the plant is the Protea mellifera, Thunb., of 
which there is a figure’ given in the Bot. Mag. t. 346. 

Haying been accustomed to collect in Madeira, Mr. Bewicke at 
once recognized the present insect as a probably new species of 
Europs ; though he informs me that he felt a little doubtful as to its 
generic identity through the fact of finding it in flowers,—a position 
in which the two hitherto detected species of Hurops have never 
been observed. Perhaps, however, the dilated tarsi of Mimema may 
well accord with this slight difference in its mode of life; though its 
close resemblance to Hurops in most of its other details and outward 
contour, would certainly lead us to anticipate a considerable similarity 
also,—which “ similarity ” is, I conceive, sufficiently established in 
the peculiarity of its food to which I have just drawn attention. 


Mimema tricolor, n. sp. 


M., lineare, angustum subopacum, parcius pubescens, piceo-nigrum ; 
capite prothoraceque alutaceis, remote punctatis, hoc subconvexo

nigro-infuscatis; pygidio valde retecto, nigrescente; antennis piceo- 
ferrugineis ; pedibus piceo-testaceis. 
Long. corp. lin. 1-1}. 

The narrow outline, smaller size, more shining surface and shorter 
elytra of the M. tricolor, in conjunction with its totally different 
colour—the head, prothorax and abdomen being dark, with the 
elytra (which, however, have their scutellary and apical regions 
more or less darkened also) pale-testaceous, and the limbs piceo- 
testaceous,—will readily separate it from the foregoing species. As 
already stated, it was found by Mr. Bewicke in company with the 
M. pallidum. 


Fam. Cryptophagide. 
Genus ATOMARIA.

Atomaria Capensis, 1. sp. 


A, ovata, convexa, pallido-castanea, parce pubescens, nitida, profunde

Two examples of this little Atomaria were captured by Mr. 
Bewicke at the Cape of Good Hope, but under what circumstances 
I cannot say. It is very nearly akin to the common European 
A, apicalis, but certainly distinct therefrom,—as will be readily 
seen when the species are placed alongside each other beneath the 
microscope. It is of a more pallid-castaneous hue, and of a rather 
more ovate (or less elliptic) form; its punctation is deeper and 
more distant, its surface less pubescent, its prothorax is less drawn- 
in anteriorly (being a trifle more rounded at the sides and of almost 
equal breadth before and behind), rather more truncated at its base, 
and more evidently margined (particularly at the lateral edges), its 
elytra are not quite so ample at their extreme apex (where they do 
not completely conceal the pygidium), and its limbs (especially the 
antennal club) are altogether darker.

A most distinct and interesting little Mycetea, differing (inter 
alia) from the common WM. hirta in its smaller size, more globose 
form, narrower and much less ample prothorax (which is apparently 
free from the transverse impression at its hinder margin), and by 
the punctures of its elytra having no tendency to be disposed in 
longitudinal rows. I possess a single specimen, captured by Mr. 
Bewicke at the Cape, but have no information as to its habits.

140 Mr. T. V. Wollaston on certain Coleopterous Insects 


The diminutive insect from which the above characters have been 
drawn has so much the resemblance of a minute Mycetwa, that it 
was not until I had examined it attentively that I perceived its 
distinctions. Its maxilla and under-lip I have unfortunately not 
succeeded (in the single specimen which I broke up) in securing ; 
but its antenne, upper-lip, mandibles, maxillary-palpi and feet, I 
have mounted carefully in balsam, and have thoroughly inspected. 
In all these details it offers sight differences from the corresponding 
ones both of Mycetewa and Symbiotes, to which it is closely allied ; 
but in the structure of its much more abbreviated antenne, which 
are 10-articulate and with a 2-jointed club, it recedes from them 
altogether,—the antenne of both of those genera having eleven 
joints, with a 3-articulated club.

(punctis haud longitudinaliter dispositis), versus humeros et apicem 
plus minus obscure subrufescentioribus ; antennis dilute testaceis, clava 
infuscata; pedibus rufo-ferrugineis. 

Long. corp. lin. 1-11. 


The present Cis has, to me at least, a peculiar interest, from it 
being of precisely the same type as the Madeiran C. Wollastonii, of 


from the Cape of Good Hope. 141 


Mellié,—a species remarkable for its oblong form, large subporrected 
head, nearly unproduced prothorax, almost naked surface, and sub- 
maculated elytra. As regards the last, however, the C. subornatus 
has but a very obscure tendency to assume that singularity of mark- 
ing which in highly-coloured examples from Madeira is often so 
apparent ; nevertheless the same tendency is just traceable in all the 
specimens which Mr. Bewicke collected, whilst in one of them it is 
particularly conspicuous. In minor details, the Cape of Good Hope 
species is much smaller, narrower, and a little more linear, than the 
Madeiran one, its clypeus is more truncated in front, its pubescence 
still shorter and more remote (being imperceptible except under a 
powerful lens), its prothoraciec punctation rather deeper and less 
dense, and its scutellum a trifle more triangular. Whether the 
C. subornatus and Wollastonii are at all abnormal in their structure, 
or whether (as I rather suspect) the generic details given by Mellic 
in his excellent monograph are not quite correctly drawn, I cannot 
tell; but certainly in both the above species the maxillary palpi are 
much longer than he has figured them, and the inner lobe, although 
very short, is more apparent (being internally membraneous and 
most powerfully ciated); the ligula, too, is considerably more 
elongated (being rounded anteriorly, and gradually contracted before 
the base); and the ultimate joint of the labial-palpi (instead of 
being ovate, as he has represented it) is narrow, sublinear and 
aciculate,—being of a very much less width than the preceding one. 
I should mention perhaps that, judging from the description, the 
C’. subornatus is perfectly distinct from the three species—Guerini, 
Capensis, and muriceus—stated by Mellié to come from the Cape of 
Good Hope.

So very closely does the present insect, at first sight, assimilate 
Hylastes, that I had regarded it, previous to a critical examination, 
as an abnormal member of that group, in which the external edge 
of the tibize were edentate. But, on closer inquiry, it proves to be 
undoubtedly one of the Curculionide, the entire structure of its 
slender, toothless, apically uncinate tibiee, and its unreceived tarsi, 
assigning it to that family. From Rhyncolus, however, to which it 
is clearly related, it recedes completely in its excessively short, broad, 
thick and subtriangular rostrum, in its very abbreviated and differ- 
ently constructed antennz (which have apparently no lateral scrobs 
for the reception of their scape), in its minute, punctiform scutellum, 
its more globose, exposed head, and in its longer feet; and I should 
consider that the Madeiran Hewarthrum is perhaps its nearest de- 
scribed ally,—though in that genus the funiculus is only 6-articulate, 
whereas in Stenoscelis it is 7-. I have two uncharacterized insects 
from the Canaries (which reside in the rotten pine-trees of the old 
Pinals of Grand Canary and Teneriffe) to which it is also much akin ; 
but in them the funiculus is, likewise, hexamerous, the antenne and 
rostrum are, both of them, differently formed, and the scrobs is very 
apparent.

The very extraordinary insect from which the above structural dia- 
gnosis has been compiled is an undoubted member (as indeed I have 
been, also, assured by both MM. Jekel and Waterhouse) of the sub- 
family Brachyderides, retaining the essential character of the various 
groups around Polydrosus, though widely differing from them all in 
its actual modifications ; and it would seem probable that the New 
Zealand Rhadinosomus acuminatus may perhaps be found to be 
amongst its nearest known allies. In its general contour and sur- 
face it is not altogether unsuggestive (to me at least) of a very ex- 
treme form of some of the longer-snouted, and more deeply sculp- 
tured, Sitonw; nevertheless its real details of structure debar it 
altogether from admission into that genus, it having scarcely a single 
point in which it absolutely agrees with it. Indeed in its elongate 
and very slender antenne (with their abruptly clubbed scape, almost 
unthickened clava, and peculiar proportions of funiculus-joints—the 
first, third, and fourth of which are subequal, whilst the second is 


144 Mr. T. V. Wollaston on certain Coleopterous Insects 


short, and the fifth, sixth, and seventh scarcely longer than the 
second), its extremely long, convex and arcuate rostrum (at least for 
the Brachyderides)—with its nearly apical and excessively oblique 
serobs, and its small, sunken and oblique eyes (which are placed 
altogether below the upper surface of the forehead)—in conjunction 
with its narrow, fusiform body, deeply sculptured, costate surface, 
apically cleft elytra, and comparatively undilated third tarsal-joint, 
it presents a combination of features essentially its own. 

When viewed laterally, its small, oblique, subreniform, deeply 
immersed eye, situated so much lower than the frontal (or rather 
nasal) projection above it, added to the remarkable curvature of its 
long and blunt rostrum—which is bent downwards at the extreme 
apex, comparatively straight along the middle, and suddenly humped 
or rounded at the base, just before its junction with the forehead (a 
structure, however, which is caused mainly by a transverse constric- 
tion across the forehead itself )—have a most comical effect—pre- 
senting a quaint analogy (in likeness) with the American Tapir 
(Tapirus terrestris), from which I have consequently borrowed its 
specific name.

elytral interstices (which, from being interrupted posteriorly, shape- 
out towards the apex a series of longitudinal tubercles), and the 
greatly developed basal joint of all its feet (though especially of its 
anterior pair), give it a character which it is impossible to mistake.

The present genus is usually known in collections as Cheirodes ; 
it has never, however, been characterized under that name, and 
therefore the above title must necessarily supersede it. The A. 
oculata is very closely related to the A. granulata, Casteln. (the 
Cheirodes scarabewoides of Dejean’s Catalogue), from Senegal,—of 
which a specimen, for comparison, has been lent me by Mr. Water- 
house: it is, however, darker (or less piceous) than that insect, 
and not quite so shining; its head and prothorax are much more 
densely and finely punctured, and its elytra are a little more per- 
ceptibly longitudinally striated. Its head, too, is a trifle more emar- 
ginated in front (the lobes being very rounded and obtuse, and not 
minutely recurved at their respective apices as in the West African 
species); its prothorax is less rounded at the sides (being somewhat 


146 Mr. F. Smith on some new Genera and Species 


narrowed, or straightened posteriorly, and with the fore-angles, though 
obtuse, less decidedly rounded off); and the two minute teeth behind 
the two larger ones, of its front-tibiz, are in the A. oculata, nearly 
obsolete. Its most decided difference, however, is in the shape of 
the eye,—which is considerably larger and more circular, and extends 
much nearer to the lateral edge (and hinder angle) of the clypeus, 
than is the case with the A. granulata. 

Although a representative (viz. the A. sardoa, Gené.) has been 
described from Sardinia, it is probable that the group is essentially 
an African one, and that many allied forms will consequently, in the 
course of time, be brought to light. In addition to the present 
species, from the Cape of Good Hope, and the A. granulata from 
Senegal, I possess a third (nearly related, I imagine, to the Sar- 
dinian one) from the Canaries, captured by myself near Arrecife, 
on the sandy shores of the island of Lanzarote. Of the A. oculata 
there was but a single example amongst the insects collected by 
Mr. Bewicke; but I have seen a second in the possession of Mr. 
Waterhouse. 


X1.— Descriptions of new Genera and Species of Exotic Hymenoptera. 
By Freperick Surra, Esq., Assistant in the Zoological Department 
of the British Museum. 


Or all the various genera of bees, there is not one which contains 
more brilliant and beautifully coloured species than Augochlora ; the 
Mexican species, described in the present paper, are remarkable for 
the extreme richness of their colouring; this genus contains the 
Halicti of the New World. They are separated, however, from the 
genus Halictus by several structural characters, and also by the 
different habit of the species; all, whose economy I have ascer- 
tained, burrow in putrescent wood, or construct tunnels under the 
bark of trees. Eight new species of Bombus are described, those 
from Mexico are amongst the most beautiful of that widely distri- 
buted genus.

Of this species Mr. Bates remarks,—‘‘ A most lovely species of 
bee, exhaling a very powerful aroma months after death. One day, 
on breaking a piece of dead branch to pieces, I came upon a row of 
cells containing these bees, already enclosed and ready to escape. 
There were about a dozen cells placed end to end, of which two con- 
tained pup; most of them escaped: I could only secure four or

Upperside (Male) black. Anterior wing with lines and triangular 
spots of orange at the base, crossed beyond the middle by an irregular 
transverse band of yellow divided by the nervures. Posterior wing with a 
line of orange at the base, forming the centre of, but not connected with, six 
diverging lines of the same colour (one of which is wider than the others 
and traversed by a black line) which pass between the nervures to within 
a short distance of the outer margin. 

Underside as above, except that it is lighter, that there is but one ray 
of orange at the base of the anterior wing, and that the posterior wing 
has the base of the costal margin orange and a band of minute white 
spots near the outer margin.

orange at the base, crossed at the middle by a large irregular spot of pale 
yellow divided into four by the nervures, one part within the cell. 
Posterior wing with a line of orange at the base, and, branching from tt 
and following the course of the nervures, several unfinished lines of the 
same colour. The outer margin towards the anal angle with some minute 
white spots.

If a butterfly or a genus resemble another (though placed, sy- 
stematically, at a distance from it), let it be in colour or in form, it 
may be expected to resemble it in other characteristics. 

The Heliconide are notable for their lability to vary. Certain 
species of Leptalis scarcely differ in general appearance from some of 
the Jthomie. Other species resemble the Heliconidée in the strange 
varieties into which they run. At first sight, Hucides Thales and 
Heliconia Vesta appear to be almost identical, A variety of H. Vesta 
scarcely differs from the insect now figured as a variety of H. Thales. 
A second variety of H. Vesta is so close an imitation of Hucides 
Eanes, fig. 1 of the Plate, that I believed it only a second variety of 
E. Thales until I noticed a difference in the position of the discoidal 
nervures of the posterior wing, as well as in the orange rays which 
proceed from the base of the posterior wing.

Upperside white. Both wings densely clouded at the base. Anterior 
wing with the costal and outer margins rufous, each with a submarginal 
band of black. A spot on the costal margin at the termination of the cell, 
a large square spot at the apex, and a round eye-like spot (its centre 
white) between the second and third median nervules all black. Poste- 
rior wing with the nervures as they approach the outer margin black. 
Two minute black spots between the discoidal nervures, and one near the 
anal angle. ‘ 

Underside white. The margins of the anterior wing and the whole of 
the posterior wing pale yellow. Anterior wing with the spot at the end 
of the cell and the eye-like spot scarcely seen. Posterior wing crossed 
obliquely by two rufous bands; the lower band marked by three small 
black spots. A minute spot at the apex, a second between the first and 
second median nervures, and two near the anal angle all black.

apex and outer margin lighter. Five silvery-white spots parallel to the 
outer margin; three of them ina line near the apex, two at a greater 
distance from the margin between the median nervules, Posterior wing 
lighter, undulated with darker colour, marked by bands and spots of 
silvery white. A band of five spots (the first within the cell, the second

Genus CoryNOMALUS. 


In the Transactions of the Entomological Society of London I have 
commenced a series of papers on the subject of the insect fauna of 
the valley of the Amazons, the result of eleven years’ research in that 
region. They are limited at present to the group of Rhopalocerous 
or Diurnal Lepidoptera, and, besides a detailed review of the genera 
and species, will contain an investigation of the general question of 
the uature and relations of the fauna, which that group of insects is 
so well calculated to illustrate. I shall not be able, nor will it be 
necessary, to treat the whole, or any considerable number, of the insect 
families in the same copious way ; it will be sufficient if I give from 
time to time, as the materials become completed, shorter essays upon 
detached families or smaller groups, communicating any facts that 
I may have observed regarding their habits, and describing the new 
species. In some groups, even of the favourite order Coleoptera, 
this task will be surrounded with difficulties in consequence of no 
recent monograph existing embodying in a connected form the 
various memoirs on the subject, thus necessitating tedious research 
for the already published descriptions in the bewildering maze of 
entomological literature. The object of the present paper is to give 


Mr. H. W. Bates on the Endomychide of the Amazon Valley. 159 


an account of the Amazonian species of the family Endomychide, 
beginning with the genus Corynomalus; and here the task becomes 
an easy one, as one of the best of the many admirable monographs 
published of late years has been given on this subject by Dr. 
Gerstaecker so lately as the year 1858. In this work the previous 
literature has been so thoroughly and conscientiously worked up 
that we may with safety take it as a starting-point, and dispense 
with research into works anterior to its date; whilst the precision 
of the generic and specific descriptions renders it a pleasant labour to 
ascertain and supplement the newly discovered forms. 

Dr. Gerstaecker in his introduction gives an elaborate review 
of the generalities relating to the family,—the whole structure 
internal and external, the position and affinities and the geographical 
distribution. But in the part of his subject relating to the habits 
and earlier states of the insects he had little to say, in consequence 
of the almost total want of information regarding the exotic species. 
It gives me great pleasure therefore to be able to contribute a little 
towards completing those portions of their history by describing the 
larvee of two of the neo-tropical genera, Corynomalus and Stenotarsus. 
Of the former I bred two species, C. discoideus and CO. subcordatus, but 
as they offered no material difference, I will describe the larva (and 
the pupa) of the former only. 

The larva of C. discoideus (Pl. XI. fig. 5) is oval and convex, fleshy 
beneath, but above having a hard granular integument, sprinkled 
with minute scales; the margins of the thorax and abdomen dilated 
and flattened. The colour above is sooty-black with the margins 
fulvous; there is a double dorsal series of transverse, oval, velvety- 
black spots, around which the minute pale scales are arranged, 
similar scales forming also pale transverse lines on the margins. 
The mandibles (fig.5 6) are simply but obtusely pointed, the palpi 
(fig. 5 c, d) taper to a point, the maxillary consisting of three joints ; 
the blade of the maxilla is narrow, obtusely pointed, curved inwards 
near the tip, and on the outside of the curved part near the tip, 
ciliated. The antenne (fig. 5 a) are elongate, cylindric, formed ap- 
parently of three joints, two basal, minute (the second perhaps only 
apparent, or separated by a constriction), and the third very long. 
There are four ocelli on each side of the head, viz. three in a triangle 
above and one below the insertion of the antennz. ‘The tarsi have 
one joint and a simple claw. The first thoracic segment is broadly 
but not deeply rounded-emarginate in front. The pupa is beset with 
horny and fleshy tubercles; there is a pair of long horny ones in 
the middle of the hind margin of each thoracic segment, and a

single one in the centre of each abdominal one; the sides of the 
mesothorax have each three long corneous spines, and the lateral 
margin of each of the first five abdominal segments is prolonged 
into a large trilobed fleshy process. 

The larva of Stenotarsus obtusus (Pl. XI. fig. 6) is oblong-oval, 

widest behind; it is beset with long and fine pale hairs; eight of 
the abdominal segments have their lateral margins prolonged on each 
side into an obtuse lobe. The colour is fulvous, each of the thoracie 
segments having two large discoidal black spots, and the sides of the 
abdomen are occupied by a broad stripe of black, leaving a broad 
central vitta fulvous, through which runs a fine dorsal black line. 
The body is not so convex as that of C. discoideus ; the prothorax is 
much longer, being semicircular, rounded in front instead of emar- 
ginate. The antenne are similar in shape to those of the Coryno- 
malus, but they are more slender, and there is no trace of the second 
apparent basal joint. I did not dissect the mouth. 
. I found these larve feeding in company with the perfect insects at 
different times on the minute fungous, or perhaps lichenous substance 
on the surface of old damp dead wood; either broken branches of 
forest trees, old barked stumps or palings around plantations, in the 
forest at Ega. When about to change, the larva (of Corynomalus) 
attaches itself by the tip of the abdomen to the surface of the wood, 
sometimes seeking a crevice for the purpose. The pupz are thus 
found in clusters of numerous individuals near the places where the 
perfect insects are feeding. 

With regard to the habits of the perfect insects, the whole family 
feed on fungi, and seem to prefer the smaller fungous growths; they 
are slow in motion (probably, like most other tropical Coleoptera, 
they are more active at night, but they do not come to lamps) and 
gregarious. Many species are amongst the commonest of tropical 
beetles, and are found wherever there is old dead wood in or near 
the forest. They are not usually found in the large woody Boleti, 
but almost always on small Boleti of loose texture, or on very 
minute, scarcely perceptible fungi. Neither are they seen on the 
very large fungi which grow in immense masses, springing up and 
decaying with great rapidity in the wet seasons on dead wood in the 
humid shades of the forest. These are more especially the food of 
the large Erotylide, which exist in equatorial America in great pro- 
fusion both as to individuals and species. Many of the smaller 
species, especially of the genera Hpopterus, Andrytus, Phalantha, 
&c., are found only on slender dead twigs, which are generally spotted 
with minute fungi. 


Mr. H. W. Bates on the Endomychide of the Amazon Valley. 161 


Dr. Gerstaecker gives statistics to show that the large-sized species 
of Endomychide (the Eumorphini) exist in far greater numbers in 
the tropics of the Old World than in those of the New. The species 
of the former are to those of the latter in the numeric proportion of 
four to one. This shows that they are far more highly developed in 
one hemisphere than in the other. It is true that the proportion is 
reversed in the case of the small-sized species (the Dapsini). In this 
group the Old- World species are to the New, in numbers, as one to four 
and a half. Notwithstanding this, on looking over a large general 
collection of the family, the great superiority of the Old- World species 
in size and variety of forms is very striking. On this account it 
would be worth while to inquire whether the large Eumorphini of 
the East do not occupy there that sphere in the economy of nature, 
which in America is filled by the large Erotylide. The latter family 
in America far surpass in variety and general individual bulk the 
members of the same group in the Old World. It would be interest- 
ing, therefore, to know whether the Humorphini in the East live 
upon the same class of large ephemeral fungi in the humid forests, 
that in America is the peculiar prey of the Erotylide. When a new 
sphere of function is opened in nature, it is apparently filled by 
members of a group whose habits already in some measure fit them 
for it and who happen to be close at hand for the purpose; thus it is 
that similar or the same functions are performed in different parts 
of the world not always by the same family or group or species, but 
frequently by an allied group or species. That sphere of action 
which is filled in one hemisphere by a certain family, in another is 
filled by an analogous or by an allied family. Instances of this 
occur in all departments of natural history; there is a beautiful 
one in the diurnal Lepidoptera, where the Heliconianz of the New 
World fill that sphere of action, which in the Old World is filled by 
the allied groups Acreeanz and Danaine.

acutis, fere opaco, sericeo-nitente ; elytris violaceo-nigris, nitidis, for- 
titer subrugoso-punctatis.—Long. lin. 5 (Q). 

Pitchy, scarcely shining. Head opake. Antenne stout, third joint 
about as long as the fourth and fifth united, the two latter of equal 
length, the sixth, seventh, and eighth joints much shorter and uniform 

‘in length; basal joint pitchy-red, the club black, opake, the rest shining 
black. Thorax much narrower and more elongate than is usual in this 
genus, fore-angles rather produced and acute, the sides from the base 
narrowed to one-third the length, then gradually dilated to near the 
apex, whence they are again narrowed to the apex, the side furrows 
not reaching to the middle, the longitudinal line faintly impressed, not 
perceptibly punctured, pitchy with a slight silken gloss. Scutellum 
shining, with a large opake fovea in the middle. Elytra nearly covered 
with large and deep punctures, many of them connected by rug, inter- 
stices convex in some places, smooth and shining, globose-convex, of 
equal breadth from the shoulders to two-thirds their length, then 
gradually narrowed to the apex, the external flattened margins very 
narrow; pitchy, with a violet tinge. Body beneath reddish-pitchy, 
including the under margins of the elytra, which are coarsely punc- 
tured. Legs pitchy-red, base of the hind femora and all the tibiz 
black. 

I have one example only of this large and distinct species, which 


was taken at Fonte Boa, on the Upper Amazons. 


2. Corynomalus rugosus, N. sp. 


C. subglobosus, piceus vix nitidus, antennis, articulis duobus basalibus 
exceptis, tibiisque nigris; thorace angusto, fere opaco, sericeo-nitente ; 
elytris eneis nitidis fortissime rugoso-punctatis.—Long. lin. 335 (Q ). 

Head pitchy-red, very finely punctured, slightly shinmg. Antenne 
with the joints short and stout, their relative lengths the same as in 
the preceding species; the basal joint red, the second pitchy ; the club 
opake, the rest shining black. Thorax similar in shape to that of the 
preceding, but considerably shorter in comparison to its breadth, yet 
notably longer than the other species of the genus, reddish-pitchy, 
darker in the middle, very obscurely punctured, shining with a very 
slight silky gloss. Scutellum with a very large central fovea. Hlytra 
short, compact, of equal breadth from the shoulders to two-thirds their 
length, then suddenly narrowed to the apex ; covered nearly throughout 
with large and deep punctures, connected in groups by irregular ruge, 
the interstices convex; brilliant dark brassy, the external margins 
moderate in breadth and ferruginous towards the apex. Breast piceous, 
scarcely shining, abdomen rusty-red, shining, the margins of the elytra 
piceous-brassy and coarsely rugose punctate. Femora and tarsi bright- 
red, tibize black. 

I have only one example of this handsome species, which I took 


at St. Paulo, on the Amazon, near the Peruvian frontier.

§ B. Elytra moderately convex, the whole of the lateral margins seen when 
viewed from above. 

a. Elytra at the base as broad or broader than in the middle (at least in 
the 3), obtuse heart-shaped. 


3. Corynomalus cireumcinctus, ND. sp. 


C. rufus, antennis rufis, articulis nonnullis ante clavam fuscis, ipsa clava 
nigra; elytris punctatis, interstitiis eequalibus subtiliter punctatis, 
nitidis, nigro-cyaneis, margine omni et regione scutellari testaceo-rufis. 
Long. lin. 8(¢ @). 

Pale red. Head rather thickly punctured, shining. Antenne 
slender, third joint shorter than the two following united, the seventh 
and eighth joints fuscous, the club black. Thorax short, the sides very 
slightly bowed outwards from the base to the apex, being broadest at 
two-thirds the length ; finely punctured, and shining rather brightly 
with a silky gloss. Scutellum plane, pale red. Elytra evenly punc- 
tured, the interstices plane, and covered with very minute punctures ; 
dark steel-blue, with the outer and basal margins and the region of the 
scutellum testaceous red. Body beneath, under-margins of the elytra, 
and legs pale red. 


This species I found only at Obydos, on the Guiana side of the 
Lower Amazon ; it was abundant on the branches of felled trees there 
in March 1859; but I have now before me only three examples, 
namely two males and one female. At first sight it might be taken 
for the C. marginatus, Fab., Gerst., which is peculiar to Guiana, 
especially as it is found on the Guiana side of the Amazons ; but it 
differs from that species greatly in the punctuation of the elytra and 
in the want of pale sutural margins. The true C. marginatus I did 
not meet with at all on the Amazons. In the punctuation of the 
elytra our species resembles C. discordeus, and it might be said to 
represent that species on the Guiana side of the Amazons, as C, dis- 
coideus does not occur in company with it, although common in 
many other localities on the opposite side of the river. 


4. CO. discoideus, Fab., Gerstaecker, Mon. der Endom. p. 151. 


I have before me one male and six females of a form which 
agrees extremely well with Gerstaecker’s description of this species ; 
six of the specimens were taken at Ega, and one at Santarem. 
Gerstaecker’s examples came from Bahia; but he had examined 
others supposed to have been found in Columbia and near Rio Janeiro. 
It appears that he did not obtain from these various localities any wider 
deviations from the normal form than those described in his work as 
varieties a and 6; on the Amazons, however, several forms more 


164 Mr. H.W. Bates on the Endomychide of the Amazon Valley. 


strongly marked than those varieties are found in company with the 
type. Icannot decide to treat them as distinct species, and shall 
therefore describe them as varieties of C. discoideus, giving to the 
most distinct a separate name. 


Var. 1. C. robustus. Thorace mox pone basin sensim ac paululum ampliato, 
elytris pone humeros sensim, apicem versus citius sed semper gradatim 
angustatis, margine pallido apud latera exiguo, apud humeros et apicem 
in maculam amplificato. Reliquis ut in typo.—Long. lin, 4 (¢). 


Of this form I have two males, one taken at Ega and one at 
Fonte Boa; the elytra are much more tapering than in the same sex 
of the type. It appears a more robust insect, the antennee seem to 
be thicker. The pale margin is extremely narrow along the sides, 
but is dilated at the shoulders, and especially at the apex, into a 
large spot. 


Var. 2. Thorace angusto, mox pone basin sensim ac paululum ampliato, 
angulis anticis acutis. Reliquis ut in typo.—Long. lin. 3 (2). 


I have two examples of this form, taken at Ega. Like C. robustus, 
the thorax is not widened from» the middle as in the type, but gra- 
dually and slightly widened from the base, rounded, and narrowed 
again slightly towards the apex. In every other respect it is the 
same as the type. 


Var. 3, Antennis tenuibus, articulo 5tio quam 4to et 5to conjunctis longiore. 
Reliquis ut in typo.—Long. lin. 33 (¢ 2). 


One example (male) from Ega, and one (female) from the river 
Tapajos. 


Var. 4. Rufo-ferrugineus, aurichalceo-micans, antennarum articulis 4-8 
fuscis, elytrorum margine preecipue humerali et apicali pallidiore ; 
elytris subrugoso-punctatis interstitiis perminute punctatis.—Long. lin. 
33 (dQ). 

I have before me two males and three females, all from Ega. They 
differ from the var. aurichalceus of Gerstaecker in the coloration of 
the antenne. They are not constant, however, in this character, 
some individuals having the antenne much darker than others; one 
having only the tips of the seventh and eighth joints fuscous. It is 
curious that the typical examples of the species taken in the same 
locality should always have the same joints of a clear red colour, 
whilst the pale ones have them always more or less fuscous. The 
elytra are more roughly punctured in this variety than in the type. 


Mr. H.W. Bates on the Endomychide of the Amazon Valley. 165 


5. Corynomalus humeralis, n. sp. 


C. rufo-ferrugineus, antennis, articulis duobus basalibus exceptis, tibiisque 
nigris; thorace lato, angulis anticis obtusis; elytris breviter cordatis, 
mediocriter subrugoso-punctatis, interstitiis perminute punctulatis, vio- 
laceis, nitidis, humeris apicibusque macula flava.—Long. lin. 33 (@ ). 

Head finely punctured, shining. Antenne with the basal joint 
bright red, second pitchy, the rest black, shining. Thorax similar in 
shape to that of C. discoideus, but having the fore-angles more produced, 
smooth, shining, finely punctured. Elytra obtuse-cordate, not quite so 
convex as in C. discoideus, covered with moderately large shallow punc- 
tures here and there connected by rugze, the interstices glossy and 
finely punctured ; violet or brassy-violet, the very prominent and glossy 
humeral callus and a subrounded spot at the extreme apex yellow. The 
body beneath shining red; the under-margins of the elytra brassy- 
piceous, rugose ; the basal half of the tibize black. 


I have two examples, both females, of this species, which I took 
at St. Paulo. 


6. Corynomalus letus, n. sp. 


C. rufo-ferrugineus, antennis, articulis duobus basalibus exceptis, tibiisque 
nigris ; thorace pone basin parum ampliato, angulis anticis prominulis, 
acutis; elytris elongato-cordatis, fortiter rugoso-punctatis, interstitiis 
convexis, subtiliter punctulatis, lete cyaneis, margine flavo apud latera 
angustissimo, apud humeros et apices in maculam amplificato.—Long. 
lin. 33 (¢)). 

Shining red. Head punctured. Two basal joints of antenna red, 
the rest black, shining. Thorax with the sides slightly and very 
gradually widened to a little beyond the middle, thence rather more 
abruptly to the apices, which are produced and acute. Scutellum red, 
smooth. Elytra more elongate than in C. discoideus, otherwise similar 
in shape, not quite so convex, roughly rugose-punctate ; the interstices 
raised and finely punctured, shining steel-blue ; the lateral margins 
narrowly edged with yellow, which colour expands at the shoulders 
into a large spot covering the humeral callus, and at the apex into a 
triangular spot. Beneath, the under-margins of the elytra are yellow, 
with a stripe along the inner edge brassy; the tibize have the basal 
half black; the rest of the under surface and the legs are red. 


One example, also from St. Paulo. Notwithstanding the consi- 
derable points of difference between this and the preceding, I am 
inclined to consider them as belonging to one and the same species. 
I think it probable that the C. apicalis of Gerstaecker is another 
variety. I believe we have to deal here with a very variable species, 
which would require a much larger number of examples to enable 
us to define its limits correctly, and unfortunately I neglected whilst

in that country to obtain a sufficient number of specimens. I think 
it likely the following is also another variety of this species. 


7. Corynomalus auratus, n. sp. 


C. rufo-ferrugineus, antennis, articulis duobus basalibus exceptis, tibiisque 
nigris; thorace pone medium paulo ampliato ; elytris ovatis, fortissime 
rugoso-punctatis, interstitiis subtiliter punctulatis, auratis nitidissimis 
apicibus flavo-rufis.—Long. lin. 44 (¢). 

Head and prothorax shining, sparingly punctured; the sides of the 
latter gradually widened after the middle, rounded and narrowed to the 
apex, the fore-angles rounded. LE lytra slightly widened from the 
shoulders to one-fourth the length, then slightly narrowed to two- 
thirds the length, afterwards gradually narrowed to the apex, the con- 
vexity regular and moderate; they are covered with large punctures, 
which are everywhere connected in groups by rugze; the interstices 
convex, highly polished, very finely and sparingly punctured, brilliant 
golden, the apex only with a yellowish-red spot. Beneath, the body 
and legs shining red; the tibize, except their apices, black ; the under- 
margins of the elytra brassy, coarsely punctured. 


The middle tibiz of the male in this species are strongly bowed, 
with the usual emargination on the inner side near the apex very 
large. I captured only one individual of this remarkably beautiful 
form, at St. Paulo, in company with the two preceding. 


8. Corynomalus Gerstaeckeri, n. sp. 


C. rufo-ferrugineus, antennarum articulis 4-8 elongatis, clava nigra ; pro- 
thoracis lateribus apud medium fere rectis, angulis anticis prominulis ; 
elytris subovatis, mediocriter punctatis, interstitiis subtiliter punctulatis, 
nigro-cyaneis, margine omni, sutura fasciisque duabus, post medium 
linea angusta in medio connexis, rufo-ferrugineis.—Long. lin, 41 (¢). 

Head and thorax shining, thickly and finely punctured. Antenne 
with the joints 4-8 more elongated than is usual in this genus, red, 
seventh and eighth joints piceous; club black. Thorax scarcely per- 
ceptibly widened from the base to near the apex, whence narrowed, 
the apical angles being produced and subacute. LElytra shaped as in 
the preceding species, but the convexity much sharper, rising more 
abruptly from the thorax, moderately punctured, the interstices thickly 
and finely punctured, blue-black; the margins and suture narrowly 
and equally edged with red; behind the middle are two narrow 
crooked fascize of the same breadth and colour as the margins, con- 
nected together in the middle by a narrower line of the same colour; 
the anterior fascia is a little behind the middle, the posterior midway 
between it and the apex. Body beneath and legs ferruginous, shining ; 
under-margins of the elytra yellow, punctured. 

The middle tibize in the male are not bowed, the apical notch short 


Mr. H.W. Bates on the Endomychide of the Amazon Valley. 167 


but deep, and the first ventral segment has a small Hel ciey in the 
middle of its hind edge. 


I captured one individual of this remarkable species at Obydos, in 
company with C. interruptus, Gerst., and C. cinctus, Fab., the extreme 
varieties of which it curiously resembles in colour. 


9. Corynomalus lividus, n. sp. 


C. ovatus, paulo convexus, rufo-ferrugineus, antennis, articulis duobus 
basalibus exceptis, tibiisque nigris ; elytris punctatis, interstitiis punctu- 
latis, brunneo-rufis parum nitidis.—Long. lin. 31(¢ 2). 

The body is: more oblong and less convex than in the other species 
of this section. Reddish. Head punctate, shining. Antenne with 
the joints slender, the first red, the second pitchy, the rest black, shining. 

Prothorax slightly widened after the middle, thence narrowed to the 

apex, the apical angles prominent and acute, punctured, shining. Elytra 

slightly but regularly convex, the convexity being nearly in continuity 
with the prothorax, its highest part at the middle of the elytra, widest 
behind the shoulders, thence narrowed and rounded gradually to the 

apex, punctured, the interstices finely punctured ; brownish-red, livid, 

the margins scarcely paler. Under surface of the body, legs except 

the tibize which are black, and under-margins of the elytra rufous, 
shining. 

This was a common species at Para, on small Boleti covering old 
palings in plantations, or on decayed branches of trees in the forest. 
I have before me three males andone female. The legs are remark- 
ably short, the middle tibize of the male very crooked near the apex, 
and the first ventral segment in the same sex is furnished with a 
minute tubercle in the middle of the hinder edge. 


10. Corynomalus subcordatus, Gerstaecker, Mon. p. 157. 


This species is common throughout the Amazon region from Para 
to St. Paulo. All the examples before me (two) from the last-men- 
tioned locality seem to belong to var. 6 of Gerstaecker, having the 
head, thorax, femora, and tarsi clear red ferruginous. The speci- 
mens from Ega (six) have the same parts more obscure, with the 
elytra brassy-violet or dark greenish-blue. The typical examples, as 
Gerstaecker mentions, occur at Para. 


11. Corynomalus quadriplagiatus, n. sp. 


C. ferrugineo-rufus sericeo-micans, antennarum clava fusca, elytrorum 
maculis duabus magnis cyaneo-nigris vix nitidis.—Long. lin. 33 (2). 
Compact, rusty-red. Head distinctly punctured. Antenne shining 
red, club fuscous. Thorax with the sides gradually but very slightly

dilated from a little before the middle, fore-angles obtuse, the hinder 
right-angled, not perceptibly punctate ; rufous shining, with a silky 
gloss. Elytra shaped like those of C. discoideus, surface coriaceous, 
evenly and moderately punctured, scarcely shining; each with two 
large blue-black patches, one larger on the basal part of the disk, one 
smaller on the apical part, leaving a rufous margin of about equal 
breadth all around them. The under surface of the body and legs 
rufous. 


I have only one example of the present species, which was taken 
at Serpa, on the Guiana side of the Lower Amazon, TI was at first 
inclined to refer it to the C. quadrimaculatus of Gerstaecker ; but the 
nature of the thoracic surface, the colour of the antenne, and the 
shape of the spots of the elytra, as described by that author, seem 
to show that we have here to deal with a different species. 


12. Corynomalus angulicollis, n. sp. 


C. rufo-ferrugineus, antennarum articulis interdum nonnullis ante clavam 
fuscis, ipsa clava nigra; prothorace apud medium angulariter ampliato, 
angulis omnibus acutis, opaco; elytris subnitidis vel fere opacis, in 
femina postice subampliatis, punctatis, nigro-cyaneis apicibus rufis, vel 
rufo-ferrugineis plagis magnis cyaneo-fuscis.—Long. lin. 31 (¢ 2). 

Rusty-red. Antenne with the third joint as long as the two follow- 
ing united, a variable number of joints preceding the club fuscous, some- 
times the extreme tips of the seventh and eighth joints alone dusky. 
Prothorax from the base slightly narrowed to one-third the length, 
then abruptly widened to two-thirds the length, afterwards slightly 
narrowed to the tip, the dilatation forming an obtuse angle; fore angles 
prominent, hind angles produced and acute, the usual grooves strongly 
marked, the whole surface opake. Elytra in the male cordate, very 
slightly narrowed from behind the shoulders to after the middle, in the 
female oval, gradually widened from the shoulders to about the middle, 
then rounded and more slowly narrowed to the apex, the shoulders 
with a long and narrow callus bordered on the inner side by an oblong 
deep fovea, the whole surface rather closely covered with moderate- 
sized punctures and slightly shining; they present the following di- 
versities of coloration :— 

1. Rusty-red unicolorous. 

2. Rusty-red, with an obscure greenish-fuscous stripe along the 
disk near the suture, interrupted in the middle. 

3. Rusty-red, each with two large subtriangular greenish-fuscous 
patches on the disk, one occupying the basal half, the other the 
apical, leaving around them a rusty red border of equal breadth. 

4. Dark-blue or greenish-black; apex, the extreme margin from 
the apex to about the middle, the basal margin and humeral callus 
narrowly pale ferruginous. 


Mr. H.W. Bates on the Endomychide of the Amazon Valley. 169 


Body beneath and legs rusty-red; the under-margins of the elytra 
thickly punctured, and in the dark varieties blue-black along the basal 
half. 


This species was common at Ega. I have described it from three 
male and four female examples, in the coloration of the elytra: 
two of them belong to var. 1, two to var. 2, one to var. 3, and two 
to var. 4; it was thus not possible to fix upon any of them as the 
type of the species, describing the others as varieties. I have there- 
fore comprehended them all in the specific definition. The species 
seems to be allied to C. 4-maculatus of Gerstaecker. 


13. Corynomalus nigripennis, 0. sp. 


C. rufus, antennis, articulis duobus basalibus exceptis, tibiisque nigris ; 
thorace apud medium fortiter rotunde ampliato, angulis posticis pro- 
ductis acutis, opaco ; elytris in femina postice ampliatis, punctatis, sub- 
opacis, cxeruleo-nigris, apicibus flayo-rufis.—Long. lin. 3} (2). 

Rusty-red. Antenne with the third joint as long as the two following 
united, the two basal joints red, the rest black, shining. Thorax before 
the middle strongly widened, rounded and narrowed more gradually to 
the tip, apical angles obtuse, hinder angles projecting, acute, opake. 
Scutellum red. Elytra in female gradually widened from the shoulders 
to two-thirds the length, then more quickly narrowed to the apex, the 
convexity very gradual from the base, the highest part placed far 
behind the middle ; the humeral callus narrow, prominent, bordered on 
the inner side by an oblong fovea, thickly covered with moderate-sized 
punctures, coriaceous, opake, except along the sutural margins, which 
are slightly shining, dark bluish-black, apex alone edged with yellowish- 
red. Beneath rusty-red, shining ; under-margins of the elytra bluish- 
black; legs red, the tibize, their tips excepted, black. 


One specimen, from St. Paulo. In the shape of the elytra this 
species would come under the following subsection ; but I believe the 
male, if it were known, would be similar in shape to that of C. an- 
gulicollis, and therefore would belong to the present subdivision. 
It so nearly resembles the dark female varieties of C. angulicollis 
that I think it very likely to be a local variety of it. It requires, 
however, a long list of specimens (at present wanting) to decide such 
questions as these. 


b. Elytra in both sexes narrower at the base than in the middle.

Dr. Gerstaecker has devoted much space to the analysis of these 
two forms with their numerous varieties, and he gives as a result 
that the latter is always distinguishable from the former by the 
following characters :—1. The antennx are always black, with the 
exception of the first two joints, which are rusty-red; 2. The disk 
of the thorax is black, the colour generally being divided into two 
lateral spots, which, though often notably reduced in size, are never 
entirely absent; and, 3. The tibie are black at the basal and rust- 
coloured at the apical half. In the typical examples, also, the black 
colour of the under side of the body, where only the middle of the 
breast and the anus are red, is characteristic. C. interruptus is an 
abundant species in Brazil, including Para, whence the Berlin Museum 
obtained its specimens, whilst C. cinctus is found only in Columbia 
and thence further northward to Guatemala. I believe both will 
prove to be only geographical forms of one and the same species, as 
the great majority of the specimens which I obtained in the Amazon 
region, from Obydos to near the Peruvian frontier, partake of the 
characters of one and the other—a natural result when two forms 
are not decidedly distinct, seeing that this district of country lies 
between the ranges of the two extreme forms. Of eighteen examples 
now before me, one only agrees strictly with Gerstaecker’s descrip- 
tion of C. interruptus; it has the thorax, the tibia, and the under 
side of the body wholly red, the first four joints of the antenne are 
red, and the fifth to the eighth are pitchy. Itwas taken at Obydos, 
on the Lower Amazons, in company with numerous individuals having 
most of the above-mentioned characters of C. cinctus. Of seventeen 
examples which I refer to C. cinctus, five have the thorax spotless 
red, the antennse (except the basal two joints) and the base of the 
tibie remaining black, as they are in the other twelve. Two or 
three of the specimens have the sides of the breast, and one also the 
middle of the abdomen, dusky ; with these exceptions, all have the 
whole of the under surface of the body clear rusty-red. In none of 
them is the disk of the thorax wholly black, as in the typical indi- 
viduals of C. cinctus. We may conclude, therefore, from these con- 
siderations, that the two forms are related to each other, not as 
species, but as geographical varieties. By attending carefully to the 
geographical distribution of forms, we shall find that there are several 
gradations of relationship between them, and not merely the two

simple ones of variety and species. There is, first, the case of 
individual differences which arise amongst the members of one and 
the same species in one and the same locality: these can scarcely 
be called varieties, as they may exist amongst the offspring of the 
same parents. Secondly, there is the case of species which are tole- 
rably constant to their type in one region whilst extremely variable 
in another. There are others which, in a distant locality, produce 
a variety which embraces all the individuals of the species existing 
there: in some cases there is an intermediate space, between the 
ranges of these varieties and their typical forms, which is unpeopled 
by either the species or its variety : in numerous instances, however, 
there exist no apparent natural barriers. The origin and main- 
tenance of these defined local varieties is a highly interesting ques- 
tion: some of them have a great resemblance to their typical forms, 
whilst others differ greatly, although often more in appearance than 
in reality. It can be shown in some instances, where the local form 
is considered on all hands to be a perfectly distinct species, that all 
the points of difference from its parent form can be paralleled sepa- 
rately by instances in undoubted varieties of species of the same 
group. The first step in specific dissimilarity is afforded us by 
Nature in those instances where two closely allied forms, each 
inhabiting its separate area, live together in an intermediate district 
without amalgamating. The dissimilarity is proved to be incom- 
plete when two forms, apparently specifically distinct, intermingle 
and produce connecting links when they meet together on the 
frontiers of their respective ranges. It is, however, I think, very 
desirable that the two or more forms in such cases should be treated 
separately in our books and placed separately in our collections, and 
therefore C. interruptus and C. cinctus may require their distinctive 
appellations. The tendency in systematic zoology to treat geographical 
forms as distinct species, has the advantage of exciting attention 
to the exact determination of the localities of specimens. A yari- 
ation, which in one case might be an individual difference of little 
importance, becomes in another a scientific fact of the highest 
significance.

as occurring at Bogota, the only district in which the species has 
hitherto been found. The colour is bright rusty-red; the elytra are 
brassy-greenish-black, the outer margins and a narrower edge at 
the base bordering the scutellum with two short imperfect fascie 
and a triangular marginal spot rusty-red; the first fascia commences 
at the margin, behind the shoulders, curves downwards, and termi- 
nates about halfway to the suture; the second arises about the 
middle of the lateral margin and extends straight across without 
reaching the suture; the spot is on the margin, halfway between 
the second fascia and the apex, and marks the place where the third 
fascia originates in the typical examples. The rest is in accordance 
with the description of Gerstaecker. 


XIV.— Characters of undescribed Species of the Family Chalcide. 
By F. Watxer, F.L.S. 


Tue following communication is the sequel of my remarks on the 
characters and distribution of the Chalcidites, which I commenced in 
the first Number of this Journal, by some notes on the Leucospide. 

This part will contain descriptions of Chalcide, and observations 
on that family, which is usually placed next to the Leucospide ; but 
there is no connecting link between the two groups, and, as it will 
afterwards appear, the Leucospide are associated with the rest of 
the Chalcidites by means of the Torymidz. 

The undescribed Chalcidee are numerous, and in the following 
pages the characters of new species will precede the sketch of the 
geographical distribution of the family. 

In these descriptions some of the generic names are retained, 
others are set aside. As in other cases, the characters of recently- 
discovered species of this family obliterate most of the distinctions 
between many of the established genera, and then ensues the alter- 
native of making many new genera or of uniting the old genera; 
and this fact is an illustration of the rule, that an increase of 
knowledge modifies or changes, or does away with, all previous 
knowledge.

XV.—Réflevions et Notes synonymiques sur le Travail de M. James 
THomson sur les Cérambycides*, avec descriptions de quelques nou- 
velles especes. Par A. Cunyronat. 


Pour un travail tel que Vindique M. J. Thomson, il était nécessaire 
que auteur eut préalablement reconnu ou fit déterminer les espéces 
de sa collection, c’est ce qu'il n’a pas fait compléetement, comme on 
le verra ci-aprés. 

Ces recherches, en effet, prennent un temps infini; il faut en outre 
une certaine habitude, une certaine sagacité dans l’appréciation des 
termes dont quelques auteurs se sont servis pour décrire la forme des 
espéces, les couleurs, les ponctuations variées, ete. 

Depuis plus de vingt ans que j’étudie plus particuli¢rement cette 
famille, je réunis des matériaux, afin d’éditer un catalogue des 
espéces décrites, quand la classification sera établie d’une maniére & 
peu prés définitive; bien que je reconnaisse chaque jour quelques 
unes de ces espéces, je suis loin de croire avoir déterminé toutes celles

de ma collection, qui est une, sinon des plus riches en belles espéces, 
du moins lune des plus nombreuses, puisqu’elle renferme au moins 
5000 de ces Coléoptéres. 

Quant 4 la partie générique, M. Thomson me parait avoir été plus 
heureux et posséder un don particulier pour cette étude. Ses genres 
sont bons et assez bien groupés. II est vrai que M. John Leconte, 
son compatriote, dont le coup d’ceil et lV’esprit méthodique avait deja 
posé la base d’une classification rationnelle pour les Longicornes des 
Etats-Unis, lui avait ouvert une voie plus large pour l’application 
aux Cérambycides de tous pays. I est regrettable que la collection 
de M. Thomson ne soit pas plus pourvue qu’elle ne l’est de ces in- 
sectes, et quil ait négligé de mentionner des genres bien connus, qui 
doivent faire partie de cette tribu, sur laquelle il reviendra sans 
doute plus tard. 

Une critique que je me permettrai de lui adresser, c’est de n’avoir 
pas adopté certains genres par le seul motif qu’ils n’auraient pas ¢té 
caractérisés d’une manicre assez détaillée, ou parceque la consonnance 
du nom, bien qu’ayant une racine distincte*, pouvait donner lieu & 
confusion ; dans ce dernier cas l’auteur a appliqué des noms nouveaux, 
ce qui est certainement plus nuisible qu’utile 4 la science.

de cet entomologiste, cette description et celles des deux espéces qui 
s’y rapportaient, ne purent étre retrouvées ; de plus, par une fatalité 
incroyable, le dessin qu’il avait fait exécuter et qui devait repré- 
senter la plus belle des deux, a subi le méme sort!

ticulata instructis. 

Var. A. Mus. Tibiis posticis simplicibus. 

Long. 4-7 lin. 

Hab. Cambogia. Collected by M. Mouhot. 

Rather longer and less robust than S. carbunculus, Hope. Head deeply 
punctured on the vertex; antennse robust, two-thirds the length of the 
body in the male; thorax (the produced apical border being taken 
away) almost transverse, apex of anterior angles very obtuse, centre of 
disk near its base impressed with a moderately deep fovea, above which 
is a more or less distinct longitudinal line, free from punctures; elytra 
covered with numerous rows of deeply impressed punctures, nearly 
regular near the suture, more confused on the sides. 

Male. Hinder thighs ovate, their lower edge near the apex furnished 
with two teeth, the outer one stout, spiniform, and armed at the base 
behind with a sinuate tooth, the inner one small; intermediate tibis 
abruptly curved. 


This lovely species is allied to S. carbunculus. 


Fam. Crioceridz. 
Genus STETHOPACHYS. 


Corpus elongatum, subcylindricum. Antenne filiformes, robuste, articulis 
secundo et tertio brevibus, longitudine fere sequalibus, moniliformibus. 
Thorax cylindricus, lateribus valde constrictis. Scutellum subtrigonum, 


194 Mr. J. 8. Baly on the Phytophaga. 


apice obtuso, Elytra thorace multo latiora, parallela. Pedes mediocyres ; 

coxis anticis conicis, contiguis, intermediis cylindricis, metasterno in- 

crassato separatis; femoribus (preesertim posticis) paullo incrassatis ; 
unguibus elongatis, arcuatis, unguiculis basi coalescentibus. Mesosternum 
elongatum, perpendiculare, apice metasterni non occultato. Metaster- 
num valde incrassatum, antice in processum validum obtusum inter 
coxas intermedias protensum. 

Type, Stethopachys formosa, Baly. 

Stethopachys represents, in Australia and the adjacent islands, 
Plectonychis, Lac., differing from that genus in possessing elongate 
claws, and in the different form of the mesosternum; this part, 
instead of being concealed by the projecting metasternum (as in 
Plectonychis), is in the present case elongate, and placed perpen- 
dicularly against the produced anterior surface of the latter, its 
truncate apex curving slightly forwards, and terminating on a level, 
or nearly so, with the lower surface of the metasternum. 


Stethopachys formosa. 


S. subelongata, subcylindrica, nitidissimo-fulva; antennis, oculis, macula 
verticali, scutello, plaga magna metapleurali utrinque, tibiis tarsisque 
nigris; thorace subconico, basi unifoveolato, lateribus medio valde 
constrictis; elytris punctato-striatis, punctis basi profunde impressis, 
striis ad apicem fere dilatatis, utrisque fasciis duabus latis, prima baseos, 
macula basali trigonata fulva includente, altera pone medium nigris.— 
Long. 4 lin. 

Hab. Australia. 

Lower portion of the face moderately produced ; antennze nearly two- 
thirds the length of the body, filiform, four basal joints nitidous, the 
others opake, second and third joints short, submoniliform, fourth 
rather longer than the third; thorax slightly transverse in front, rather 
broader at the base, sides deeply constricted in the middle, base above 
impressed with a small deep fovea, middle of the disk impressed by 
several irregular rows of fine but distinct punctures, which form to- 
gether a broad longitudinal vitta; scutellum truncate; elytra much 
broader than the thorax, slightly narrowed towards their apex, each 
elytron impressed with ten rows of distinct punctures, their interstices 
plane, tenth row sulcate, the punctures on the basal half of the four or 
five inner rows large and deeply impressed, the puncturing of all the 
strise very fine towards their apex; hinder thighs shorter than the 
abdomen; claws large, gradually increasing in length from the first pair 
backwards. 

Stethopachys Javett. 

S. oblongo-elongata, picea, nitida; abdomine pallidiore; antennis nigris ; 
elytris punctato-striatis, fulvis, limbo postico piceo.—Long. 3 lin. 

Hab. New Caledonia. 


Mr. J. 8. Baly on the Phytophaga. 195 


Antenne nearly equal to the body in length, moderately robust, 
filiform, four basal joints shining, the rest opake, second, third, and 
fourth joints short, gradually increasing in length; thorax subconic, 
subeylindrical, sides constricted, the constriction being scarcely visible 
from above, surface smooth and shining, remotely punctured, the punc- 
tures on the sides confused, those on the middle of the disk arranged 
in two or three longitudinal rows, base impressed with a deep foyea ; 
scutellum elongate-trigonate, truncate; elytra much broader than the 
thorax, lateral margin slightly produced at the shoulder, concave below 
the latter, above convex, slightly flattened on the back, each elytron 
with ten regular rows of punctures, fulvous, the apical half of the 
outer limb broadly edged with piceous, beneath shining piceous ; abdo- 
men edged with obscure fulvous; hinder thighs shorter than the 
abdomen, moderately incrassate; metasternum more swollen than in 
the preceding species. 


I owe the specimen from which the above description is taken to 
the kindness of M. Javet, after whom I have named the species. 


Genus Crioceris, Fab. 
Crioceris Salléi. 


C. elongata, subcylindrica, viridi-metallica, subnitida, subtus nitida, pilis 
adpressis tenuibus obsita, eenco vix micans; antennis (basi excepta) 
nigris; thorace nitido, longitudine latitudini fere sequali, cylindrico, 
lateribus medio sat constrictis, fortiter transversim sulcato-strigoso, 
basi fovea parva impyresso ; elytris crebre fortiter subrugoso-punctatis, 
utrisque intra marginem unicarinatis, disco exteriore prope medium 
fovea magna ovato-rotundata impressis.—Long. 4-43 lin. 

Hab. Oaxaca. Collected by M. Salle. 

Antenne four-fifths of the length of the body, slender, filiform, 
slightly increasing in thickness towards their apex, third and fourth 
joints short, equal, obconic, four basal joints shining metallic green, 
the rest black, opake ; elytra parallel, much broader than the thorax, 
indistinctly impressed transversely below the basilar space (in their 
punctation they differ entirely from any of the similarly coloured known 
species, their surface somewhat resembling shagreen); legs slender, 
subelongate, thighs very slightly incrassate, the hinder pair scarcely 
reaching to the extremity of the elytra in the male, much shorter in 
the other sex. 


Fam. Eumolpide. 


Genus TRICHOCHRYSEA. 


Corpus oblongum, valde convexum, supra pube suberecta vestitum. Caput 
latum, thorace fere immersum; fuciei margine inferiore valde emargi- 
nato, utrinque in dentem brevem robustum producto ; epistoma parva,

fere obsoleta; antennis gracilibus, dimidio corporis longioribus, articulo 
primo incrassato, quinque sequentibus filiformibus, duobus basalibus 
brevibus, eequalibus, ceteris paullo longioribus, inter se equalibus, 
quinque ultimis modice dilatatis, valde compressis; mandibulis ro- 
bustis, apice dentatis; dabro transverso-quadrato ; palparum articulo 
ultimo oblongo-ovato, apice truncato. Thorax transversus, dorso sub- 
eylindricus, lateribus declivi-marginatis. E/ytra thorace paullo latiora, 
breviter oblonga. Pedes robusti, tbs intermediis extrorsum ante 
apicem emarginatis, wegweulis dentatis. Prosternum transverso-qua- 
dratum ; antepectoris processu antero-laterali subcuneiformi. 
Type, Zrichochrysea Mouhoti, Baly. 


Distinguished from Calomorpha, Stal, by the toothed clypeus, the 
more slender antenne, the broader and more distinctly margined 
thorax, the more prominent jaws, &e. 


Trichochrysea vestita. 


T. oblonga, subcylindrica, cupreo-zenea, nitida, subrugoso-punctata, un- 
dique pilis griseis suberectis obsita; antennis gracilioribus, basi fulvis

produced on either side into a stout tooth; labrum smooth, rufo- 
geneous; antennge more slender than in the former species, the terminal 
joints less incrassate; thorax subglobose above, closely punctured, 
either side, just within the anterior angle, furnished with a slightly 
raised smooth tubercle. 


Trichochrysea Mouhoti. 


T. oblonga, subcylindrica, viridi-zenea, aureo-tincta, pube brevi sub-

Fam. Gallerucide. 


Genus Drampuipsa, Gerst. 
Cladocera, Hope. 


The insects known and described by Hope, Gerstaecker, and others, 
under the above generic names, appear to form a single natural 
genus, the species varying greatly in the degree of serration or even 
flabellation of the antennee, but agreeing in all their other characters. 
I would divide the genus into three sections, formed on the degree of 
variation of those organs, 

Sectio I. Antennis flabellatis in utroque sexu. 
IJ. Antennis serratis aut subserratis in uno aut utroque 
sexu. 
III. Antennis simplicibus. 

Cladocera of Hope having been already used, Gerstaecker’s name, 
Diamphidia, must be adopted; but from these authors having founded 
their genera on the extreme states of the antenne, either term is 
characteristic only of a certain number of species in the genus, 


Diamphidia Bohemana. 


D. oblonga, convexa, fusco-alba; pedibus, antennis, verticis macula 
utrinque, thoracis maculis quinque scutelloque nigris ; elytris subcrebre 
punctatis, utrisque margine apicali, macula humerali, altera subapicali 
fasciisque duabus maculeeformibus (harum prima infra basin (maculis

subtus obscurior, abdominis segmentorum macula utrinque parapleu- 
risque piceis. 

Mas. Antennis valde flabellatis. 

Fem. Auntennis modice flabellatis. 

Long. 5-63 lin. 
Hab. Port Natal. 

Thorax with its apical margin bisinuate, the side border rounded 
behind, narrowed and sinuate in front; the anterior angles produced, 
subacute; upper surface with five large black spots placed (2-3) on 
the disk, and in addition two or three others, smaller and punctiform 
(sometimes obsolete), on either side, close to the lateral and basal mar- 
gins; the first of the maculeeform fasciz on the elytra is placed nearer 
the base than in D. pectinicornis, the second (situated immediately 
behind the middle) is regularly curved, instead of being flexuose as in 
the above-named insect, and the subapical and submarginal patch 
occupies the place of three much smaller spots, which form, in the old. 
species, a transverse subapical band: legs entirely black, with the ex- 
ception of a narrow space on the upper and lower edges of the hinder 
femora. 


In addition to the different arrangement of the black markings 
on the elytra, as indicated aboye, this species may be separated from 
D. pectinicornis (Oliv.) by the form of its thorax; in D. pectinicornis 
the anterior margin is nearly truncate, the sides are more regularly 
rounded, and the anterior angles, although distinct, are not produced. 

Diamphidia Bohemani belongs to the 1st section.

Type Pseudodera xanthospila, Baly. 


Very closely allied to Crepidodera, but divided from that genus by 
the tapering antenne and by the constriction of the upper surface 
of its neck. The transverse groove also at the base of the thorax 
terminates just within the short longitudinal grooves, not being 
continuous with them as in Crepidodera.

Type, Phrynocepha pulchella, Baly. 


The present genus, which belongs to the Anisopodous section of 
the family, must be placed near Crepidodera,—the form of the an- 
tenn, the peculiar shape of the head in the male, and the irregu- 
larly punctured elytra separating it from that genus.

Type, Leptarthra abdominalis, Baly. 


Mr. J. 8. Baly on the Phytophaga. 203 


The insects composing the genus Leptarthra have hitherto been 
placed in Celomera; the resemblance, however, is only external, the 
structure of their antenne, together with all their other characters, 
differing so completely as to render it unnecessary to point out the 
distinctive marks here. 


Leptarthra abdominalis. 


L. ovata, postice paullo ampliata, convexa, nitida, obscure viridi-metallica, 
purpureo-micans ; abdomine elytrisque rufo-testaceis, his fortiter sub- 
crebre punctatis, antennis scutelloque nigris.—Long. 43-5} lin.

hinder disk impressed with three large deep circular fovez arranged 
transversely in a gentle curve; scutellum semiovate; elytra deeply 
punctured, the disk of each with two or more nearly obsolete longi- 
tudinal vitte ; anal segment of abdomen in the male impressed by a

Hab. Northern India. 

Antenne slender, equal in length to the body; thorax at the base 
nearly twice broader than long, sides nearly straight, narrowed from 
their base to the apex, the anterior angles prominent, their apex sub- 
acute, upper surface sculptured nearly as in the preceding species, the 
transverse groove in front more deeply impressed, strongly sinuate in the 
middle, and sending a short longitudinal groove backwards to the cen- 
tral fovea; scutellum rather narrower than in Leptarthra abdominalis ; 
surface of the elytra punctate-striate, each stria being formed of several 
irregular rows of punctures, the outer strize and those near the suture 
more confused and often quite lost, interspaces impressed with scattered 
punctures which vary both in number and depth, sometimes being as 
deep as those forming the striz themselves; on the suture, a short 
distance below the scutellum, is a broad shallow depression ; anal seg- 
ment of abdomen in the male impressed by a deep semiovate fovea.

than the thorax, convex, transversely depressed below the base, basilar 
space on each elytron distinctly elevated, the raised portion being 
bounded externally by a longitudinal depression within the humeral 
callus, and beneath by the transverse depression, surface finely and

Although unwilling to found a genus on a single sex (and that

metasternum quite sufficient to separate Metalepta from all allied 
generic forms.

sutural angle rounded, convex, flattened and slightly depressed on the 
suture in front, surface less closely and coarsely punctured than in 
the following species; elytra in the female broader and shorter, each 
elytron being narrowly ovate, with the sutural margin rather straighter 
than the other; on the disk of each are four or five indistinct vitte ; 
abdomen very convex, impressed on either side within the lateral 
border with a row of large deep fovere, the margin itself obscure rufo- 
fulyous.

XVII.—On certain Coleoptera from St. Helena. By T. Vernon 
Wottaston, M.A., F.L.S. 


Any material from so remote a spot as St. Helena, which is about 
1200 miles from the nearest point of the African coast, must of 
necessity prove highly interesting,—more particularly to the geo- 
graphical naturalist, for whom a more isolated field could scarcely 
perhaps be found. True it is that the island must have greatly 
deteriorated, in a scientific point of view, during the last 300 years, 
since but few traces of the forests now remain which are said to have 
clothed it at its discovery; nevertheless in the small parts which 
are still left untouched, and have escaped the ruthless hand of 
“civilization,” some glimpses of its ancient glory may doubtless be 
discerned; and from the general character of these “ fragmentary 
remains” we must needs build up our estimate, as correctly as we 
ean, of the primeval forms with which this little oasis of the mid- 
Atlantic was originally stocked. In the present paper I do not 
intend to make any allusion to the stray insects which have been 
recorded, from time to time, by other naturalists from this distant 
rock,—most of which, like the Calosoma Helene (brought from thence 
by Mr. Darwin, and described by the Rev. F. W. Hope), are peculiar 
to it; but, having lately received from my friend Mr. Bewicke of 
Madeira a most important batch of 14 species, collected by himself 
(whilst touching there, en route from the Cape, on the 21st of July 
last), during two or three hours’ research “amongst indigenous 
woods on the extreme summit* of the island,’”’ I propose merely to 


* By reference to an encyclopzdia, it would appear that St. Helena rises 
abruptly from the Atlantic, and attains an elevation (at its highest point) of 
about 2700 feet above the sea.

208 Mr. T, V. Wollaston on certain Coleoptera 


give a critical enumeration of them, and so add a mite to our small, 
but growing, knowledge of that curious eccentricity which is so fre- 
quently conspicuous amongst remote insular forms. 

On glancing over the following catalogue, it will be perceived that, 
of Mr. Bewicke’s fourteen species, two belong to the Geodephaga, 
eight to the Rhynchophora, and one to the Lamellicornia, Phytophaga, 
Heteromera, and Pseudotrimera, respectively, —indicating a marvellous 
majority for the weevils, which, if we remove from the list the 
Pristonychus complanatus (which is clearly an introduced insect, and 
one which has established itself in almost all the Atlantic islands), 
will number nearly two-thirds of the entire lot! And if we con- 
sider, further, that the six extra-Rhynchophorous forms belong to 
well-known genera (Calosoma, Pristonychus, Heteronychus, Longi- 
tarsus, Opatrum, and Cydonia), and that at least three of them are 
identical with widely-distributed species, whilst the eight Ahyncho- 
phora are all of them endemic both in species and genus—and not 
merely “ endemic,” but anomalous in structure in proportion to the 
remoteness of their habitat,—we shall scarcely fail to be struck by the 
conviction that the Curculionide will, in all probability, be found to 
play a most important part in the Coleopterous fauna of St. Helena. 
Indeed, in the remarks under Microwylobius, | have expressed my 
belief (from the mere diversity of configuration presented by the five 
exponents there described) that it is almost certain that the members 
of that abnormal little group are (in species) locally abundant, and 
that consequently many additional representatives may yet be looked 
for: and since the same might be urged, with no less force, for that 
extraordinary genus Notiowenus, there is every reason for suspecting 
that the Rhynchophora of this mountain-island are (in proportion to 
its size) both numerous and eccentric.

A single specimen (a female) of this fine Calosoma was taken by 
Mr. Bewicke at St. Helena. In its obscurely brassy and rugulose 
upper-surface it belongs to the same type as the African species 
C. Senegalense and rugosum ; nevertheless from the former of these 
it is abundantly distinct. With the latter, judging from the deserip- 
tion, it is much more nearly allied; though I am informed by Mr. 
F. Smith, who has kindly compared it for me with examples in the 
British Museum, that it is not only more depressed and with the 
coppery punctures smaller, but that the prothorax is more deeply 
rugose in front and behind, and that the legs are slenderer and with 
the pile on the underside of the feet very much softer,—being, in 
fact, fine hairs, instead of stiff bristles. Apart from the characters, 
however, which separate it from the C. rugoswm in particular, I may 
just add, that its very small and short prothorax (which is almost 
equally rounded before and behind, and has its posterior angles, 
although backwardly produced, very obtuse), in conjunction with its 
transversely-imbricated and equally-convex elytral interstices and 
its shortened limbs (at any rate in the female sex, of which I can 
alone speak), should be especially noticed.

Three specimens of this insect were taken by Mr. Bewicke at 
St. Helena; and I have seen another, from the same locality, in the 
collection of Mr. Fry. It is a species of Mediterranean latitudes, 
occurring in Portugal, Spain, the south of France, Italy, Sicily, 
Egypt, and the coast of Barbary; and one which also abounds in 
most of the Atlantic islands. It is said to be common throughout 
the Azorean archipelago; and I have myself captured it in Madeira 
and Porto Santo, as well as in Lanzarote, Teneriffe, and Palma (of 
the Canaries). It is recorded by Dejean as having been found even 
in Chili.

Geotrupes arator, id., Syst. Eleu. i. 21 (1801). 
Heteronychus arator, Burm., Handb. der Entom. y. 94. 


A single specimen of this Heteronychus, taken by Mr. Bewicke at 
St. Helena, agrees precisely (so far as I can detect) with numerous 
examples of the same species which he captured at the Cape of Good 
Hope, from which locality it was originally deseribed by Fabricius 
in 1792. It may possibly be identical with the H. Sancte-Helene 
of Hombron and Jacquinot, characterized in the Zoological portion 
of Dumont d’Urville’s ‘ Voyage au Pole Sud sur les Corvettes l’Astro- 
labe et la Zélée’ (p. 105. pl. 7. f. 6); but if such should be the case, 
the latter cannot be more than a variety (if indeed that) of the South 
African arator ; and I may add, that my friend Dr. Schaum of Berlin, 
to whom [ lately transmitted the St. Helena specimen for comparison, 
and who has paid great attention to this department of the Lamelli- 
corns, at once identified it with the Fabrician species.

Having given a full diagnosis of this curious genus in my late 
enumeration of “ the Atlantic Cossonides,”’ published in the ‘ Trans- 
actions of the Entomological Society of London,’ accompanied with 
lengthened observations on its structure and affinities, I will not 
repeat any of them in the present paper. The five exponents re- 
corded below (and which were there characterized) appear to be 
congeneric with the minute Curculio, from St. Helena, described by 
M. Cheyrolat under the title of Microwylobius Westwoodi ; and, from 
the great diversity of their outward contour, it would seem far from 
improbable that many allied forms yet remain to be detected, and 
that, like the Cauwlotrupides in Madeira, they will be found to be 
an extensive insular assemblage. For all critical and diagnostic 
remarks I must refer to the above-mentioned memoir.

The remarkable little insect for which I have been compelled to 
erect the present genus has, at first sight, so much the appearance 
of a small Acalles, that (before critically overhauling it) I had placed 
it aside as a member of that group. On closer examination, how- 
ever, its funiculus is composed of only five joints (instead of seven), 
whilst there is no trace of a pectoral groove for the reception of its 
rostrum. It is consequently excluded from the whole subfamily 
Cryptorhynchides by the latter circumstance alone ; whilst from the 
Cossonides, with some of the genera of which it would agree as 
regards the former, it is altogether remote. Its affinities are indeed 
extremely doubtful; but, upon the whole, I should have been in- 
clined to suspect that the Cholides would perhaps have received it 
more readily than any other of Schénherr’s subfamilies, had not Prof. 
Lacordaire assured me that in his opinion it could not properly be 
associated with the exponents of that department. Nevertheless I 
may add that M. Jekel concurred with me in regarding the Cholides 
as its most probable location,—adding that, when thus situated, it 
would find a ‘*somewhat allied neighbour, in general outline and 
many analogous characters, in the genus Pylarus, from the Cape of 


212 Mr. T. V. Wollaston on certain Coleoptera 


Good Hope.” Nevertheless it must be admitted that its real position, 


in a natural classification, is very questionable.

Regarding the affinities of this singular genus there cannot be 
much question,—its straightened antennee, which are implanted on 
the upper surface of the rostrum, immediately within the eyes, in 
conjunction with their lax triarticulate club, its sub-basal prothoracic 
line, slightly abbreviated elytra, and the construction of its second 
and third tarsal joints at once assigning it to that small section of 
the Anthribide of which, I believe, the only recorded genera are 
Caranistes (from Madagascar), the partially saltatorial Arcocerus 
(from Java, India, &e.), and the saltatorial Choragus and Xenor- 
chestes (from Europe and Madeira respectively). Nevertheless in 


from St. Helena. 213 


external contour it must be admitted that it is most anomalous, pre- 
senting such an exact resemblance to the ordinary Curculionide (as, 
for instance, some of the Atlantic Cyclomides, such as Atlantis and 
Laparocerus), that it is scarcely possible at first sight to help associ- 
ating it with the members of that family. It is on this very account, 
however, peculiarly interesting; for, if there had been any doubt as 
to the real affinity of the Orthocerous and Gonatocerous divisions of 
the Rhynchophora, assuredly such a genus as Notiowenus, which com- 
bines the structural features of the former with the almost precise 
outward likeness of the latter, would have gone far to dispel it.

A single specimen of this extraordinary insect was taken by Mr. 
Bewicke ; and I have much pleasure in dedicating it to its captor, 
to whose researches we are indebted for the several novelties de- 
scribed in the present paper. At first sight it has much the outline 
and colouring of a Madeiran or Canarian Atlantis,—its dark-brown, 
densely-clothed surface, relieved only by small and indistinct patches 
of dull cinereous scales, somewhat calling to mind certain members 
of that group. Not to mention many other characters, its almost 
impunctate, though rather alutaceous and subopake surface (which, 
however, can only be perceived when the pubescence is removed), 
in conjunction with its unpunctured elytral striz, and its deeply- 
impressed and curved sub-basal prothoracic line, deserve to be espe- 
cially noticed.

The black, shining, and less pubescent surface of this beautiful 


214 Mr. T. V. Wollaston on certain Coleoptera 


little Notiowenus, its strongly and closely punctured prothorax (the 
sub-basal line of which is raised, instead of impressed, and not much 
curved), added to the convex interstices, deeply-crenate striz, and 
the numerous small and bright rufo-testaceous patches of its elytra, 
will at once abundantly distinguish it. Like the last species, a single 
specimen only was captured by Mr. Bewicke.

The greenish-brassy alutaceous surface and pale elongate limbs 
of this little Longitarsus, in conjunction with the broad, largely- 
developed basal joint of its four anterior male feet, will sufficiently 
characterize it. A single specimen only was taken by Mr. Bewicke. 
It is quite distinct from any species with which I am acquainted ; 
and Mr. Waterhouse, who has been working lately at the Halticide, 
assures me that he knows nothing at all like it.

An insect of a very wide geographical range,—being recorded from 
Senegal, the Cape of Good Hope, Caffraria, Madagascar, the islands 
of Bourbon and Mauritius, the East Indies, and Java. It is a most 
variable species; and whatever doubt may be entertained as to the 
claim for separation of some of the extreme states which have been 
ascribed to it, there can at least be no question about the St. Helena 


from St. Helena. 215 


form, which must be regarded as the typical one,—the specimens 
described originally by Fabricius (in 1775), in the Banksian collec- 
tion, being from St. Helena. It is probably the common Coccinella 
of the island. Four examples were taken by Mr. Bewicke (who 
likewise captured it at the Cape of Good Hope); and I have seen 
others in the possession of Mr. Fry. 


Fam. Opatride. 


Genus Oparrum. 
Fabricius, Syst. Ent. 76 (1775). 
14. Opatrum Hadroides, n. sp. 

O. latiusculum, nigrum, breviter fulvescenti-pubescens ; capite lato, ad 
latera ante oculos rotundato-ampliato (nec angulato) ; prothorace brevi, 
ad latera vix rotundato, apice haud profunde emarginato, angulis anticis 
subrotundatis (nec longe porrectis acutis), angulis posticis acutis (sed 
haud longe retrorsum productis) ; elytris parallelis, punctato-striatis, 
ad humeros rectangulis. 

Long. corp. lin. 43. 


Although unwilling to erect a new species in such an extensive 
and obscure genus as Opatrum, yet, after a careful comparison of the 
present insect with a long series of Atlantic forms (from Madeira, 
the Canaries, the Cape de Verdes, and the Cape of Good Hope,—two 
from each), I am induced to do so in this instance, since the remote- 
ness of its island-habitat renders it @ priori probable that it will be 
found to be peculiar to St. Helena. The whole of the winged Opatra 
(i. e. the Gonocephala of Solier) are moulded so nearly on the same 
type, that small differences which might be disregarded in many 
groups become important with them; and, after a close examina- 
tion, I am convinced that there are no characters so much to be 
depended upon as the exact form of the dilated sides of the head 
(immediately in front of the eyes), and the relative depth of the 
emargination (accompanied with the greater or less prominence and 
acuteness of the anterior angles) of the prothorax. The 0. Hadroides 
is very nearly akin to a species which was taken by Mr. Bewicke at 
the Cape of Good Hope; but is altogether rather larger, broader, and 
more parallel, its head isa little wider, with the lateral expansion, in 
front of the eyes, more rounded (or less angular at the extreme point 
of projection), its prothorax is less deeply scooped-out in front, with 
the anterior angles (consequently) less porrected and more obtuse; the 
hinder angles also are somewhat less produced, and its shoulders are 
more rectangular. Although narrower and on a smaller scale, it has 


216 Mr. J. O. Westwood on a new Genus 


a slight primd facie resemblance, in general contour, to the more 
parallel-sided Hadri (such as the H. alpinus and Paive),—a circum- 
stance which has suggested its trivial name.

Note.—Mr. Westwood, being prevented by want of leisure from 
studying the affinities of Chalenus, has requested me to do so, 
and assign the insect to its proper family in the great group of 
Phytophagous insects. This (although feeling far less adequate to 
the task than the author himself) I have endeavoured to do, placing 
the genus amongst the Gallerucide, as I consider that the structure 
of the mouth and tarsi, together with the approximation of the an- 
tenne at their base, point out that family as its true position. In 
the form of the body it approaches somewhat to the Gallerucide 
anisopode, the broad, flattened, and perpendicular head in particular 
bearing a striking likeness to the same part in Lowoprosopus, a genus 
of Halticide ; but, on the other hand, the slender hinder thighs, not 
fitted for leaping, and the extremely narrow and weak prosternum 
place it without doubt in the Isopodous section of the family. I 
think it ought to stand not far from Celomera, Erichs. In my 
own cabinet I possess a second species of the genus, collected by 
Mr. Wallace, which differs in many respects from Mr. Westwood’s ; 
of this I have ventured to give a description in the present note.—

XIX.— Contributions to an Insect Fauna of the Amazon Valley.— 
LerrporrreRA—Parinionipm. By H. W. Bares. 


In the two principal works on the Diurnal or Rhopalocerous Lepi- 
doptera, viz. the ‘ Spécies Général’ of Dr. Boisduval, and the ‘ Genera 
of Diurnal Lepidoptera’ of Doubleday and Hewitson, the family 
Papilionide is made to consist of a limited number of genera, of 
which the restricted genus Papilio is considered the type. In the 
present treatise I propose to extend it so as to embrace also the 
family Pieride of the same authors, reducing the two groups to the 
rank of subfamilies. The Papilionidee differ from the Pieride only 
in having the abdominal border of the hind wings excavated, and in 
the tarsal claws being simple instead of bifid—characters which, 
when the whole division Rhopalocera is carefully studied, I think 
will be found to be of subordinate rank. Both families agree in 
possessing six perfect legs in both sexes, in the pupa being secured 
by the tail and a silken girdle across the middle in an upright posi- 
tion, and in the wing-cells (at least of the hind wing) being always 
closed by perfect tubular nervules. The importance of these cha- 
racters in distinguishing family groups becomes evident only when 
the whole division is studied; it will then appear also, I think, that 
the Papilionide have been erroneously placed at the head of the 
Rhopalocera, a position accorded to them by nearly all Lepidopterists. 
On this subject a few remarks will not be out of place as preliminary 
to a review of the Amazonian species. It may be of minor import- 
ance in what order a number of natural families are successively 
treated in a descriptive work ; but it is necessary that clear and 
correct ideas, as far as possible, should be acquired of their true 
relations to each other. 

All the Heterocerous Lepidoptera or Moths have six perfect legs 
in both sexes. This is the universal rule also in the orders allied to 
Lepidoptera, viz. Trichoptera and Hymenoptera; it cannot be with- 


of the Amazon Valley. 219 


out significance, therefore, that several families of Butterflies or 
Rhopalocera have only four perfect legs, the first pair being more or 
less aborted or rudimentary. This character is not inconstant or 
intermittent ; it is absolutely universal throughout an immense 
diversity of generic forms. The degree of abortion of the fore legs, 
moreover, is different in the sexes, the male taking the lead in the 
atrophy of the organs ; the nature of the sexual difference also being 
constant and characteristic of large groups of genera constituting, as 
I believe, natural families. Thus, in this division of the order we 
have, first, two families in which the fore legs are perfect in both 
sexes , then, two in which they are imperfect in the male, but per- 
fect in the female—in the one being slightly, in the other greatly 
aborted in the former sex ; and, lastly, one in which they are im- 
perfect in both sexes. The Papilionide and Pieride of authors 
possess six perfect legs; they are, with the Hesperide, the only 
groups of the division which are in this condition, and they should, 
I think, on this account occupy the lowest places in the series of 
families; whilst that group in which the atrophy of the fore legs is 
most complete should be placed at the head, as being the farthest 
removed from the Heterocera, and therefore the extreme develop- 
ment of the Rhopalocerous type. 

A natural classification of the Rhopalocera, then, according to this 
view, would commence, in an ascending series, with the Hesperide. 
In this family all the legs are perfect, and the hind tibie, with only 
a few exceptions, have two pairs of spurs, as in nearly the whole of 
the Heterocera. Next to them would follow the Papilionide (and 
Pieride), which, although quite unconnected with the Hesperide, no 
connecting links between the two families being known, have like 
them six perfect legs. Then would succeed the groups with imper- 
fect fore legs. The characters thus derived from the structure of the 
legs harmonize well with those furnished by the metamorphoses, 
and partly with those derivable from the wing-neuration, as will be 
seen in the following table, wherein I have attempted to establish 
five families, subordinating to them as subfamilies the greater part 
of those proposed by authors. 


Family 1. Hesperide. Six perfect legs in g 2; hind tibie, with 
few exceptions, having two pairs of spurs. Larva in- 
habiting a rolled-up leaf; pupa secured by many threads, 
or enclosed in a slight cocoon. 


Family 2. Papilionide. Six perfect legs in ¢ 2. Wing-cells (at 
least of the hind wings) closed by perfect tubular ner-

vules. Pupa secured by the tail and a girdle across 
the middle in an upright position. 

Subfam. 1. Papilonine. 

Subfam. 2. Prerine. 


Family 3. Lycenide. Six perfect legs in 9; four in <4, the fore 
tarsi wanting the tarsal claws, but densely spined 
beneath. Wing-cells (except in Humaus*) not closed 
by perfect nervules. Pupa secured by the tail and a 
girdle across the middle. 


Family 4. Erycinide. Six perfect legs in 9 ; four in ¢, the fore 
tarsi consisting only of one or two joints, and spineless. 

Subfam. 1. Erycinine. Pupa recumbent, flattened beneath, 

secured by the tail and a girdle across the middle. 

Subfam. 2. Stalachtine. Pupa not flattened beneath, secured 

rigidly by the tail in an inclined position, without 
girdle. 

Subfam. 3. Libytheinw. Pupa suspended freely by the tail. 
Family 5. Nymphalide. Fore legs imperfect in both sexes: in the 2 

wanting the tarsal claws ; in the ¢ the fore tarsi aborted, 
consisting only of one or two joints. Pupa suspended 
freely by the tail. ’

or less atrophied.

* This genus constituted a distinct family in the system of Boisduval (Spec. 
Gén.); it was incorporated with the Lyceenide by Westwood in Doubled. & Hew. 
Gen. Diurn. Lep. If the lower disco-cellular nervule prove to be aborted con- 
stantly in the numerous aberrant genera of Lycenide of Kastern Asia, the genus 
Eumeus wight form a subfamily of Lyceenide founded on the closure of the 
wing-cells. 

t Theransformations of Stalachtis have not yet been recorded. The statement 
here made is founded on unpublished observations of my own on St. Calliope.

Acreine will be discussed in a paper on those groups which I shall publish 
shortly. 


of the Amazon Valley. 221 


In the last of these families, the Nymphalide, there are certain 
genera and species which exhibit a still further degree of atrophy 
of the fore legs than that indicated in the description, and prevailing 
in the majority of the species ; but this extreme point of imperfec- 
tion is not common to definite series of genera, and therefore is not 
of any great systematic value. It shows, however, a tendency to 
further advance in the direction which we have seen indicated in the 
successive families; and the genera which furnish such instances 
must be considered as exhibiting the highest development of the 
type of the family, and as being the farthest removed from the 
division Heterocera. These genera, however, belong to subfamilies 
widely different in many respects, and placed far apart in the re- 
ceived classifications, but which agree in the wing-cells being 
closed by perfect nervules. The nature of the atrophy is not, how- 
ever, the same in both. Thus, in the Heliconine several genera 
have in the ¢ the fore tibiz rudimentary, the tarsi having entirely 
disappeared ; in one genus (Sais) the femora also are much reduced 
in size. The fore legs of the @ are in the same insects very slender 
and feeble, but exhibit all the articulations, except in some species 
where the fifth appears to be wanting; they cannot be said, however, 
to be more rudimentary than in the typical Nymphalide. On the 
other hand, in the Satyrine there are many species, but probably not 
whole genera, which have the fore legs extremely reduced in both 
sexes. In Lymanopoda they are very short, weak, and similar in 
appearance in the males and females; and in several species of 
Satyrus the tarsi in the female are jointed, but are deprived of spines 
at the end of the articulations, and are similar in clothing to those 
of the males. In Cerois the fore legs of the males are of the same 
rudimentary structure as that of the Heliconine above mentioned ; 
thus, in the Satyrid there are some species in which the females 
as well as the males show a great degree of atrophy of the organs in 
question, and in others the males only. 

The atrophy of the fore legs in large numbers of the Diurna is no 
new fact in Lepidopterology ; it was known to the earliest writers on 
the order; but the difference of structure according to sex remained 
long undiscovered. No application or mention is made of it, except 
with regard to the Erycinide by Dr. Boisduval in his ‘ Species 
Général,’ published in 1836. The order, in fact, has not generally 
had the advantage of being studied in a scientific spirit. A precon- 
ceived notion seems to have prevailed that no important characters 
were to be derived from the structure of the adult insects. Latreille 
ealled the order ‘the stumbling-block of entomologists.”? The 


222 Mr. H. W. Bates on the Papilionid 


difference in the sexes of the Lyczenide with regard to the legs was 
not detected until 1843, when Drs. Adolf and Otto Speyer published 
a treatise on the subject. This, which was called by Erichson in 
his Annual Report ‘a beautiful discovery,” aided very much to com- 
plete our knowledge of the different variations of structure*. Ten 
years afterwards, viz. in 1853, the legs were first employed as the 
leading feature in the classification of the Diurna by two authors, 
viz. Lederer in Austria, and Wallengren in Sweden. Both applied 
their system, however, only to the European species, and neither 
seemed to recognize the distinction between the Lycznide and 
Papilionide. Wallengren+ divided the section into—1. Tetrapodes, 
2. Hexapodes, and 3. Heteropodes. Lederert{ also proposed three 
divisions (excluding the Hesperide), viz.: 1. All feet perfectly deve- 
loped in both sexes—Equites (Papilionide), Pierides, Lycenides. 
2. Fore legs in ¢ imperfect, in 2 perfect—Erycinides and Liby- 
theides. 3. Fore legs rudimentary in both sexes—Nymphalides, 
Danaides, and Satyroides. Of these two arrangements the latter 
appears to me the most natural, and is the one nearest approaching 
the classification I have here proposed. 

The Papilionide are not represented in the Amazon region by a 
great diversity of forms. Of the nine described genera of the sub- 
family Papilionine only one is found, and of the sixteen genera of 
Pierine only four. The genera, however, are rather numerously 
represented in species, and most of the species in individuals. Of the 
genus Papilio there are found 35 species and subspecies, besides 8 
well-marked local varieties—forming altogether about 28 true or good 
species ; of Leptalis 13, of Pierts 11, of Callidryas 7, and of Terias 17. 
Many of them, however, are very closely allied to each other. I have, 
in the review of the species, adopted the principle of discriminating and 


* Since writing the above, I have acquired a copy of Horsfield’s ‘‘ Catalogue of 
the Lepid. Ins. Mus. East India Company.” I find therein that the discovery 
alluded to by Erichson had been made by Dr. Horsfield, and published in 1828. 
This author investigated thoroughly the structure of the fore legs, both male and 
female, in the Lycenide. He found a single claw at the tip of the male tarsi in 
some genera ; in others the claws of the female were much reduced. The Hast 
Indian Archipelago contains a number of aberrant genera of this family, which 
are probably transition-forms to Pieride and Erycinidx. It is remarkable that 
these important investigations of Dr. Horsfield should have remained so long 
inutilized by the leading authors of works on the Lepidoptera.

naming every well-marked local variety, referring it, however, to its 
supposed parent form wherever the evidence was sufficient to warrant 
it. The same comparisons and inferences, however, which are usually 
applied to affiliate local forms and varieties, I consider it logical and 
necessary to apply to reputed species. Discussions upon the deriva- 
tion and relationship of local varieties are of great scientific interest ; 
but they only reach their true value when they are applied also to 
the apparently more distinct forms. It is not, I conceive, according 
to the spirit of inductive science that the method which is applied to 
prove the natural derivation of a semi-distinct form should be re- 
linquished on the incorporation of the variety with the species,

(P. Cresphontes) inhabiting the Southern States of North America.

I met with one example only, on the Upper Amazons, of this most 
remarkable species. It has no near ally in its genus, and has the 
appearance of a Heliconia, especially of Lycorea Atergatis, rather than 
that of a Papilio. 


Subfamily Prrrin zx. 


This group, which forms so conspicuous a feature in the faunas of 
temperate latitudes and in the tropics of the Old World, is poorly 
represented in the forest plains of the Amazons. The genera and 
species seem to be most numerous in grassy, open and mountainous 
countries, or in districts where the forests are scanty ; they abound 
in the varied mountainous regions of Columbia. Only four genera 
are found in the Amazon valley: viz. Leptalis, Pieris, Callidryas, 
and Terias; and of these, Pieris is represented by very few species. 
Leptalis, although numerous in species or subspecies, does not ex- 
hibit so great a diversity of forms as it does in the Andean valleys of 
Columbia; the species in the Amazon region are also extremely rare ; 
they inhabit the shades of the forest, and mimic the different species 
of the dominant group Heliconine, in whose company they are 
always found, thus suggesting the idea that it is only by means of 
this close adaptive resemblance that they escape total extinction. 
The other four genera found in Tropical America are, Euterpe, Na- 
thalis, Colias, and Gonepteryx. Of Euterpe 34 species have been 
described ; but although one has been found in Guiana, none inhabit 
the Amazon region. Nathalis has one representative in Venezuela. 


230 Mr. H. W. Bates on the Papilionidee 


Colias in tropical America is confined to the highest plateaux of 
Columbia, reappearing in several specific forms in the plains of the 
southern temperate zone ; no trace whatever of the genus being found 
in the Amazon valley. Lastly, Gonepterya, although approaching 
nearer the equator than Colias—Venezuela on the north and Per- 
nambuco on the south each furnishing a species—is also quite absent ; 
G. Leachiana, included by authors in this genus, being undoubtedly 
.a true Callidryas. 

The genus Leptalis was'supposed, both by Boisduval and Doubleday, 
to have a real affinity with the Heliconidew, as the species not only 
resemble that family in shape, markings, and colours, but they also 
have, as Doubleday states, a structural similarity to species of 
Ithomia (a Heliconideous genus) in the neuration of the wings. The 
two groups furnish a most curious instance of deceptive analogical 
resemblance. There is, in truth, the widest possible difference be- 
tween the two in all essential characters of affinity—a fact which a 
“careful study of the legs in the Rhopalocera will satisfactorily prove. 
As to the resemblance in the wing-neuration, this character loses its 
importance on account of its adaptive nature, being dependent on the 
shape of the wings, habits, and strength of flight, and varying con- 
sequently in nearly allied genera.

I found two examples ( ¢ ) of this singular and rare species on the 
banks of the Tapajos in 1852. They were flying in company with 
Methona Psidii, and their likeness to that species was so great that 
I could not distinguish the one from the other on the wing. The 
mimetic resemblance is carried to the smallest peculiarities—to the 
coloration of the antenne and the white spotting of the abdomen. 


2. L. Egaena, nob. 
P. Amphione, Cram, 252 £. F., local var. 

3 9. Darker than the Surinam type as figured by Cramer, both as to 
the isabella ground-colour and the yellow belts. The inner belt of the 
fore wing is reduced in breadth, and the short, macular subapical belt is 
enlarged into a broad band; the hind wing beneath is suffused with 
fuscous, the isabella-colour existing only as narrow lines, and the paler 
yellowish part is restricted to two or three oval spots near the apex. 


of the Amazon Valley. 231 


The true Amphione of Cramer I did not meet with on the Amazons ; 
but at Ega, on the upper river, the present well-marked local form 
occurred. Itis a species which offers, in other countries of Tropical 
America, several more or less strongly-marked varieties, many of 
which have been described, without mention of the relationship, as 
distinct species. The Ega form flies in company with the Ega var. of 
Mechanitis Polymnia, viz. M. Eqgaensis, and it is difficult to distinguish 
the two species on the wing. It is well worthy of remark that the 
S.E. Brazilian form, L. Astyoche, also adopts the livery of Mechanitis 
Nisea, the local form of MW. Polymnia of the same district. 


3. L. Tapajona, nob. 
P. Laia, Cram. 232 c. v., local var. 


©. Differs from Z. Lata in having the costal stripe of the fore wing 
and the first macular belt attached thereto of the same yellow colour as 
the second or subapical macular belt. 


I did not meet with the true Zaia in the Amazon region. vi 
Tapajona occurred only on the banks of the Cupari, an affluent of the 
Tapajos, in 3° 40'S. lat. 


4. L. Lysianax, Hewits. 
L. Lysianax, Hewits. Exot. Butt. Lept. f. 19 *. 


This is another local form of Z. Zaia. In the colour of the costal 
stripe and the belt of the fore wing it resembles Z. Tapajona, but 
the belt is not interrupted as in that subspecies: it wants, however, 
the yellow apical belt, at least on the upper side ; beneath, it exists 
as “three small white spots.” If this insect were taken really 
within the Amazon region, it must have been at Pebas or Nauta, on 
the upper river. 

5. L. Theonoé, Hewits. 
L. Theonoé, Hewits. Exot. Butt. Lept. 2. 5. 


Found on the banks of the Cupari, an affluent of the Tapajos, in 
company with /thomia Flora, with which it has a striking mimetic 
analogy; it was exceedingly rare, whilst the Jihomia was very 
abundant. On the Upper Amazons T'heonoé did not occur, nor 
Ithomia Flora, but in their stead a number of species of Jthomia 


* L. Lycosura, Hewits., represented on the same plate, f. 18, 20, I suspect does 
not belong to the Amazonian fauna. M. de Gand, who supplied these insects, 
collected more at Moyobamba, on the eastern chain of the Andes, than in the 
Amazon valley, but unfortunately his collections from different parts were mixed 
together. 


232 Mr. H. W. Bates on the Papilionide 


allied to the latter, and a number of forms of Leptalis, of such a 
nature that they cannot be considered as specifically different, allied 
to the former. Most of these forms mimic in that region specifically 
the Ithomie alluded to; they seem to have become changed in colours 
and markings in strict relation to them; one or two of them, how- 
ever, resembling in the same close manner species of Stalachtis, a 
genus belonging to a widely different family. Although no ento- 
mologist would consider these forms as entitled to specific rank, I 
think it better to distinguish them, in order to bring out in a clearer 
light the curious circumstances connected with them. 


6. L. Melanoé, nob. 


3 2. Shape, general colour, and design of the wings as in L. Theonoé. 
It differs in the black lines and borders being much broader, less di- 
stinctly limited on their edges, and in the transparent spaces being 
suffused with dusky atoms. The orange submarginal stripe of the hind 
wing beneath is well defined, but less sharply so than in LZ. Theonoé, and 
less clear in colour, being sprinkled with dusky atoms. 


Found on the Upper Amazons, at St. Paulo, in company with 
Ithomia Onega, which it closely resembles, and which I consider is 
in that locality a local modification of Ithomia Flora of the di- 
stricts nearer the Atlantic seaboard. The Leptalis, as usual, was 
excessively rare, whilst the Zthomza abounded in individuals. 


7. L. Erythroé, nob. 


3S Q. Very similar to the preceding in shape and in the dusky suffusion 
of the transparent spaces. It differs conspicuously in the three spots of 
the apical part of the fore wing being of a vivid orange colour and opake ; 
they are sometimes confluent, and then form a large elongate spot or belt. 
The submarginal orange-red stripe of the hind wing beneath is well de- 
fined and clear in colour; the black inner edging is narrower than in Z. 
Melanoé. 


Occurs at St. Paulo in company with the /thomie of the locality, 
one of which, J. Chrysodonia, nob., it mimics specifically. The 
mimicry is more exact in some individuals than in others, producing 
the impression that there is a striving after close imitative adapta- 
tion. Neither the Zeptahs nor the Jthomia occurred in any other 
part of the country, except the limited locality here mentioned. 


8. L. Leuconoé, nob. 


3 Q@. Shape of wings same as the preceding. In the fore wing the 
basal stripe and the inner two of the subapical spots are transparent ; the 


of the Amazon Valley. 233 


third elongate spot is orange-red, opake. The hind wing has a very broad 
dusky-black margin, but the whole disk and the nervures are milky- 
white. 


The white disk of the hind wing gives this form a peculiar facies. 
In this character, as well as in the colours of the fore wing, it re- 
sembles exactly another Jtéhomia abundant in its locality, viz. J. 
Ilerdina, Hewits. The two fly together, and cannot be distinguished 
when on the wing. Ithomia Ilerdina is closely allied to I. Flora. 


9. L. Argochloé, nob. 


d. Outline of wings same as the preceding. In colours it is extremely 
like L. Antherize (Hewits. Exot. Butt. Lept. 12) and LZ. Fortunata (Lucas, 
Ann. Soe. Ent. Fr, 1854, p..58. pl. 3), having near the apex of the fore 
wing a rather broad, oblique, semitransparent white belt ; in all other re- 
spects it cannot be distinguished from Z. Melanoé. It differs from L. 
Antherize (a Mexican species) in the nervures which cross the white belt 
being black instead of white. From Z. Fortunata (also a Mexican species) 
it differs in the widely different direction of the red submarginal stripe of 
the hind wings beneath. In LZ. Fortwnata the stripe is represented as 
terminating before the apex of the wing, whereas in LZ. Argochloé, as well 
as all its allied forms, it curves round within the apex, and nearly or quite 
meets a similar red subcostal stripe. 


L. Argochloé mimics Ithomia Virginia, Hewits., a species inhabit- 
ing the same locality, viz. St. Paulo.

LI. Lysinoé, Hewits. Ex. Butt. Lept. 3, 4.—Ega. 

Var. 1. Ib. f. 18.—Ega. 

Var. 2. The basal stripe of the fore wing orange-red, opake. The hind 
wing orange, except the costal margin (which is white in ¢, black in 2), 
the apex, a short stripe proceeding therefrom, and a narrow posterior 
border, which are black. (92 ¢)—Kga. 

Var. 3. Similar to var. 1; but the basal stripe of the fore wing is also 
orange-red, and the hind wing is dusky- black, leaving a rather narrow 
orange-red submarginal stripe. (Q)—St. Paulo. 

Var, 4, Similar to the type; but the costal and apical spots of the fore 
wing are confluent, and the orange submarginal stripe of the hind wing 
is narrow and abbreviated. (¢)—St. Paulo, 


The typical form is found only at Ega, where also are found vars. 
1&2; vars. 3 & 4 occurring only at St. Paulo, in company with the 
more striking modifications, which I have described above (sp. 6-9) 
under separate names. ‘The type does not mimic any species of 
Tithomia of its locality, but it has a most deceptive resemblance to 


234 Mr. H. W. Bates on the Papilionidee 


a species of the Erycinide genus Stalachtis, viz. S. Phedusa, var. 
Egaensis, nob.* Var. 2 is a doubtful mimetic analogue of Jthomia 
Illinissa of the same locality ; and var. 3 resembles very much, on the 
wing, Stalachtis Calliope. It must be remarked that the species of 
Stalachtis are quite as abundant in individuals as the /thomie, as this 
fact will probably tend to explain why the Leptalides mimic some- 
times one and sometimes the other. The remaining varieties seem 
to be indeterminate in their analogies,

both species exist in company in Guiana as well as in the Amazon 
region.

Q. P. Psamathe, Fabr. Ent. Syst. iii. i. 207. 647. 


¢d. Very much resembles the same sex of ZL. Kollart, Lucas, of Rio 
Janeiro; the wings, however, are longer and more pointed, the black 
apical portion of the fore wing has a similar central white spot, but the 
under surface of the hind wing beneath is pallid-yellow instead of 
ochreous. 


I took both sexes of this species at Para.

3d. Fore wing long, narrow, lanceolate; the black apical part is con- 
tinued as a narrow marginal line to the hind angle, and is destitute of 
white spot; the hind margin of the posterior wing has a short black 
border near the apex. 


I think this is searcely distinguishable from the preceding species; 
however, all the examples taken at Pard belong to LZ. Psamathe, 
whilst all found on the Upper Amazons are conformable to LZ. Licinia. 
The ¢ has a so much smaller portion of the hind border of the wings 
black than the 9, according to Cramer’s figure, that I at first con- 
sidered it a distinct species under the name of L. Galanthis, as quoted 


* This var. is distinguished by the great breadth of the orange-red belt of the

On the Amazons this species inhabits the same districts as P. 
Phaloé. It inhabits the shades of the forest; but the males are 
found also in open places, and resort to the moist margins of puddles 
and streams: the females I have never seen, except within the forest ; 
they are much rarer than the males, and are coloured in imitation of 
certain Heliconidse found in the same localities. The species has a

those localities I find do not differ from those taken by myself in the 
Amazon region.

@. Size and shape of wings same as ¢. Fore wing black; a large 
triangular spot in the middle of the base prolonged externally towards 
the hind angle and a narrow stripe parallel to the hind margin orange ; 
a short oblique belt between the end of the cell and the apex yellow; 
beneath the same. Hind wing black; a short stripe parallel and near to 
the costa and a broad stripe along the middle of the wing, very broad on 
the abdominal edge and narrowing towards the apex, orange: beneath 
black; a stripe parallel and near to the costa and a narrow one along the 
wing passing over the end of the cell and expanding into a patch near 
the apex reddish-yellow ; between these a stripe from the abdominal 
edge to the end of the cell bright red. Antenne black, whitish towards 
the tip; body above yellowish-brown, beneath light yellow. 


This species has similar habits to P. Pyrrha ; it is much more local ; 
it occurs on the Upper Amazons from Ega to the head waters of the 
Napo, and also on the banks of the Cupari, an affluent of the Tapajos. 
The female resembles in shape and colours species of Heliconidee ; 
its habits also are very similar to those of the Heliconide. 


7. P. Leptalina, n. s. 


$. Small, 1” 10” in expanse; wings elongate. Fore wing with the 
costa strongly arched, apex obtuse, and outer margin bowed outwards ; 
pure white, the costal border broadly dusky to the end of the cell; the 
apical third of the wing and a narrow outer border thence to the hind 
angle black ; a white oblique belt crossing the black part from the costa to 
the third median branch, not reaching the outer margin, leaving a narrow 
black stripe on the inner side: beneath the same, except that there is a 
submarginal row of five white spots along the outer border ; base sulphur- 
yellow. Hind wing short and rounded, white; a broad border from the 
anal angle to the costa, narrowest near the apex, black: beneath white; a 
stripe parallel to but distant from the costa, meeting at the apex a mar- 
ginal border same in dimensions as that on the upper surface, black; in 
the middle of the black border is a stripe of orange-yellow extending from 
the anal angle to the apex ; base sulphur-yellow. Body above blackish, 
beneath white ; antennee black. 

This species resembles in colours, and in appearance on the wing, 
Leptalis Eumelia. Found at St. Paulo, in the forest. I did not 
meet with the female, which would doubtless be coloured like the 
same sex in the two preceding species.

it is not, however, abundant. The males resort to the moist margins 
of waters in company with other Callidryades of the same sex; but 
they are often seen also in the alleys of the forest. It is a remark- 
ably rapid and strong flier. I do not know why authors have placed 
the species in the genus G'onepterya ; 1t does not consort at all well 
with the other species of that genus, and agrees in all generic cha- 
racters with Callidryas.

Q. Intermediate in colours and design between Argante 9 and Fu-

similar to those of Eubule 9, except that they are much broader at the 
apex of the fore wing; there is also a large brown spot between the 3rd 
and 2nd median branches, and another smaller between the 2nd and 
Ist, both disconnected with the outer margin. Beneath the markings 
are similar to those of Ewbule 2, but the whole surface is sprinkled with 
reddish specks almost as in Argante 2 ; and the rufous margin at the 
apex is much broader. 


Cramer figures the males of two distinct species as the sexes of one ; 
and subsequent authors have quoted the figures without criticism. 
His figure C. pl. 163 is evidently the well-known ¢ Hubule. I 
find no example of the ¢ of the present species in my collection of 
the genus ; but I have three 9 agreeing with the description I have 
given above, which I strongly suspect to belong to the same species. 
They were taken in company with Hubule 2, in open places at

It seems to be uncertain whether the description of Linnzus

In a doubt of this kind we have no remedy but to be guided by the 
next subsequent author, who by a better description or figure fixes 
thename. Cramer’s figure undoubtedly applies to the South American 
species. It is extremely abundant.

The 2 varies extremely in size and colour, viz. from 1” 8” to 2” 8'” 
in expanse, and from pallid white to a rich clear orange-yellow. 
Throughout all the variations the shape of the black border remains 
constant ; it may also be known by the great length of the terminal 
joint of the palpi. The ¢ also varies considerably in the breadth of 
the pale powdery margins of the wings, and in the depth of the basal 
yellow colour. It is the most abundant species of the genus. The 
females are confined to the thinned parts of the forest and its margins, 
where they may be seen depositing their ova on low trees of species 
of Mimosa. The males congregate by myriads, in company with an 
almost equal number of Hubule and a few of all the other species of 
the genus, on the moist sands or mud on the banks of rivers. In 
the height of the dry season (October) very extensive migrations 
take place. I once travelled with a fair wind on the Lower Amazons 
about eighty miles between sunrise and sunset, and during the whole 
of the journey the air teemed with these butterflies, all crossing the 
river, there from three to five miles broad in one direction, viz. from 
north to south. On the Upper Amazons they settle on the moist 
sands in dense masses of many yards square, all with wings upright 
and closely packed together.

strong, sustained flight and migratory instincts of the species of this 
genus, that it is found throughout the tropical and subtropical zones 
of the whole world, and that the species of the two hemispheres

closely resemble each other; so much so, that one, Alemeone of 
Bengal, was considered by Cramer to be identical with Statira ¢ ; 
the latter being, as we have seen, the most numerous and migratory 
of all the American species.

narrowing to the hind angle, its inner edge with many shallow sinua-

with a narrow border, sometimes reduced to a series of spots, blackish. 
Beneath: fore wing pale yellow, spotless, sometimes whitish on the disk ; 
hind wing pale yellow, sometimes whitish on the disk, two small black 
spots at the end of the cell, and a waved dusky irregular belt across the 
wing, sometimes obliterated.

known by having beneath a large orange-yellow spot at the apex of 
each wing: the colour above and beneath of all the wings is yellow ; 
the fore wing has a broad black outer border ; the hind wing is gene- 
rally spotless, but it sometimes has a narrow dusky macular border. 
The orange spots beneath, however, in some specimens are faint, and 
in others quite disappear, when the insect becomes almost undistin- 
guishable from certain 2 examples of Nise, Cram. The two sexes 
differ so much, that I should not have supposed they belonged to 
the same species if I had not captured them in copuld. It is a very 
common species in thinned parts of the forest and semicultivated 
places on its borders throughout the Amazon region. There is a 
nearly allied species found at Rio Janeiro. 


4. T. Flavilla, n. s. 


Q. Expans. 1''7''-1"9'"., Size and shape of 7. Deva. Wings rounded, 
clear yellow. Above: fore wing clear yellow, the extreme costal edge 
dusky ; an outer border, broad on the costa, narrowed to the hind angle, 
multisinuate within, silky violet-black; the base with two short black 
streaks: hind wing clear yellow, spotless, or with a very slight dusky 
border. Beneath clear yellow, spotless, except that there are sometimes 
one or two minute black spots at the end of the hind wing-cell. 


This species differs from all others known to me in the clear spot- 
less yellow colour of the wings beneath. It is a very common species 
in the same localities as 7’. Deva. The description is drawn up from 
five examples. 

5. T. circumeineta, n. s. 

3. Expans. 1" 7'’-1" 8'". Wings rounded, yellow. Above : fore wing 
yellow, the costa narrowly bordered with dusky; an outer border, very 
broad on the costa, moderately broad at the hind angle, its inner edge with 
many very faint sinuations, silly violet-black : hind wing yeliow, with a 
narrow border from the apex to the anal angle, somewhat regular in 
width, violet-black. Beneath paler yellow, spotless, except that there is 
one small black spot at the end of the cell. 


Para, and other localities. I strongly suspect it to be the ¢ of 7’. 
Flavilla. tis very near 7’. tenella, Bdy. ; but his description better 
suits a nearly allied 8. Brazilian form which has generally distinct 
undulated dusky marks across the hind wing beneath. 


6. T'. Nise, Cram. 
2. P. Mse, Cram. 20. x. 
This species varies in colour, being sometimes uniformly ochreous- 
yellow, as represented in Cramer’s figure, sometimes of a very pale

yellow ; and sometimes the hind wing is much paler in tint than the 
fore wing. Although a very common species in open grassy, flowery 
places on the borders of the forest, I never detected it i copuld. 
The male, however, I believe to be an insect scarcely distinguishable, 
except by its smaller size, from the same sex of 7’. Deva, as described 
above. 

7. T. venusta, Boisd. 


T. venusta, Bdv. Sp. Gén. 658. 8. 


This species very much resembles 7. Nise 2 , but is smaller in size. 
It is taken in company with that species, and is probably a mere 
variety of it. 

8. T. Elathea, Cram. 


o. P. Elathea, Cram. 99 c. D. 


@. Wings rounded. Above: fore wing clear yellow, costal border 
sprinkled with dusky atoms ; an outer border, beginning about the middle 
of the costa, and terminating in a point at the hind angle, multisinuate 
on the inner side, violet-black : hind wing white, with a yellowish tinge ; 
outer margin near the apex broadly dusky, through which the nervures 
appear of a darker colour. Beneath: fore wing whitish, the costal border 
and apical third ochreous-red, disk yellow; hind wing ochreous-red, with 
an undulated line across the wing darker, and two spots at the end of the 
wing-cell black. 

According to Cramer’s figure of the ¢, the under surface of the 
wings is of an ochreous-red hue, with dusky marks, and the upper 
surface has an abbreviated posterior black stripe on the fore wing. I 
met with numerous ¢ individuals agreeing with this type, and in 
company with them numerous ¢ conformable to the description 
given above. Boisduval in his description (Sp. Gén. 664.19) has 
mingled this form with one or two others, probably distinct species, 
and amongst them the following. 


9. 7. Lydia, Felder. 
3. T. Lydia, Felder, Lep. Nov. Columbie, no. 50. 


2. Very similar in size and shape to Elathea 2. Above: fore wing 
very pale whitish-yellow, costal border broadly dusky; outer border very 
broad, especially on the costa, terminating rather broadly at the hind 
angle, multisinuate within, violet-black: hind wing white, outer border 
very broad, irregular, black, terminating long before reaching the anal 
angle. Beneath: white; fore wing with the fore part and apex bright 
yellow ; hind wing sprinkled with dusky atoms. 

The ¢ is distinguishable from the same sex of Elathea by the under- 
surface heing pearly white, slightly sprinkled with dusky atoms, and by

border. 


Common in grassy, flowery places at Santarem and other localities. 


10. 7. albula, Cram. 
P. albula, Cram. 27 &. 


This species is 1” 6-1" 7’ in expanse. The two sexes are alike ; 
I have taken many pairs in copuld. It is known by its size, by the 
black outer border of the fore wing terminating obtusely before 
reaching the hind angle, and by the under-surface being spotless 
white, except a sulphur tinge at base of the fore wing. The hind 
wing is generally spotless above, but sometimes it has a narrow black 
border; the outer border of the fore wing sometimes terminates 
abruptly. The insect I have seen in collections generally under this 
name is not the albula of Cramer. It is a very common species in 
thinned parts of the forest, flying feebly and low over the herbage. 


11. 7. marginella, Felder. 
T. marginella, Felder, Lep. Nov. Columbiz, no. 53. 


This, which appears to be a distinct species, resembles much 7’. 
albula: it differs in the black border of the fore wing reaching the 
hind angle, and in the existence of a black border of moderate width 
in the hind wing. Taken at Ega. 


LAD. clara, 1.8. 


Expans. 1’ 3”. Wingsrounded. Above: fore wing white, the costa at 
the base dusky; an outer border of moderate breadth, slightly uneven on 
its inner edge, and terminating in an obtuse point before the hind angle, 
black: hind wing white, spotless. Beneath: spotless white, tinged with 
sulphur-yellow at the base of the fore wing. 


This is the species which I have seen in most collections under 
the name of albula, Cram. It is, however, a much smaller insect, 
and the posterior termination of the outer black border of the fore 
wing is different. It was common in the same situations as 7’. 
albula. 

13. T. Mana, Boisd. 
T. Mana, Bdy. Sp. Gén. 681. 49. 


Both sexes of this species are alike in colour and markings, accord- 
ing to individuals I have taken in copuld. It is a rather smaller 
insect than 7’. albula, and the wings are rather shorter and broader. 
Above it has a broad costal dusky border, and the outer black border 


244 Mr. H. W. Bates on the Amazonian Papilionide. 


terminates squarely before reaching the hind angle. Beneath it 
differs from 7’. albula in having a broad yellow margin to the fore 
wings, and in the hind wings being yellowish, with a black spot at 
the end of the cell, and a series of dusky marks across the wing 
behind the cell. It varies in size from 1” to 1” 5’, and is closely 
allied to 7. Agave of Cramer. 

Pard, in open grassy places. 


14. 7. Tapeia, n.s. 

Expans. 1. Wings rounded. Above: fore wing white; a somewhat 
narrow outer margin, terminating obtusely much before reaching the hind 
angle, black ; hind wing spotless white. Beneath: fore wing with the disk 
white, the apical and outer margin yellow, and the base sulphur-yellow ; 
hind wing uniform ochreous-yellow, spotless. 

Pard. It is distinguished from all the other species of the genus 
known to me by the peculiar uniform ochreous-yellow colour of the 
under-surface of the hind wings. 


15. 7. LInrina, n. 8. 

Expans. 1’. Wings slender, rounded. Above: fore wing somewhat 
elongate, subtriangular, obtusely pointed, white, the apex alone with a 
somewhat narrow black border; hind wing rounded, white, spotless. 
Beneath: all wings white, their bases tinged sulphur-yellow. Antennz 
short, brown, ringed with white. 

Para. 

16. 7. Leucoma, n. s. 

Expans. 1’. Fore wing elongate, apex obtuse, outer margin strongly 
bowed outwards; above white, with an outer border of variable breadth 
black. Hind wing with the costa at the base strongly dilated; above and 
beneath white, the posterior border sometimes narrowly edged with dusky. 

This species very much resembles 7’. Brephos in shape ; it is found 
in company with it on the Upper Amazons. 


17. T. Brephos, Hiibn. 


Mancipium Brephos, Hibn. Samml. Ex. Schmett. 
Terias Brephos, Boisd. Sp. Gén. 684. 53. 


Some examples have the costa of the hind wing dilated at the 
base, others not; this may therefore be a sexual character. The 
wings are entirely spotless. The neuration of the fore wing in this 
and the preceding species does not differ from that of the larger 
species of the genus, although 7’. Hlvina, a similar dwarf species 
inhabiting 5.E. Brazil, differs considerably in this respect. In the 


M. A. Cheyrolat—éflewions et Notes synonymiques. 245 


hind wing, however, all three differ from the rest of the genus in the 
upper radial being emitted as a branch of the subcostal after the cell, 
and not connected with the cell by means of an upper disco-cellular. 
1’. Brephos is common in thinned parts of the forest throughout the 
country, hovering slowly over the carpet of Lycopodia which covers 
the ground in those localities. 


Note.—The species of Terias are a most difficult study, and it is 
with some hesitation that I have described several as new. Their 
specific characters are not at all trenchant; the peculiar markings 
which may serve to distinguish well-characterized examples of a 
species are subject to become obsolete in other examples ; the species, 
again, present many local varieties in different parts of their area 
of distribution. The genus is found in the tropical and subtropical 
zones of both hemispheres, including Australia, Madagascar, and other 
African Islands; eighty-six species having already been described. 
Although inseets of feeble flight, they fly directly onwards like most 
of the Pierine ; and this, together with the food-plants of the larve 
(Leguminos) being of general occurrence, may account for the sin- 
gular fact of the very wide distribution of many of the species as 
well as of the genus. Several species allied to 7. Hecabe, found in 
the island of St. Domingo, are not distinguishable from similar forms 
occurring in the Malay Archipelago. In describing the new Ama- 
zonian species I have only selected those which were illustrated 
by many examples, or were strikingly distinct, and have abstained 
from uselessly adding to the number of obscurely known forms by 
including many others in my collection which do not accord with 
any already described. 


XX.—Réflexions et Notes synonymiques sur le Travail de M. Jamxs 
Tuomson sur les Cérambycides, avec descriptions de quelques nou- 
velles espéeces. Par M. A. CHEvro.at. 

[Second et dernier article. ] 

J’ar visité dernicrement la collection de Cérambycides (Longicornes, 

Latr.) de M. Thomson au point de vue du systéme qu’il a adopté. 

Je dirai tout d’abord que cet Entomologiste ayant, depuis mon 1¢ 

article, acquis beaucoup de choses nouvelles dans cette famille, rec- 

tifié des erreurs et rappelé a leur place certains genres omis, cette 
classification générale me parait rationnelle, heureuse méme et devoir 
mériter des éloges, mais l’ouvrage dans le désordre ot il est publié 
avec les intercalations successives manque d’homogénéité. 

En outre, la base, qui devait étre la détermination rigoureuse des

espéces et leur synonymie, péche, comme. on a déja pu le voir et 
comme on le verra encore ci-aprés; puis les espéces décrites trop 
légérement laissent souvent planer des doutes*. 

Peut-étre M. Thomson eut-il pu s’entendre avec moi pour me 
soumettre tout ce que renfermait sa collection, en ce qui concerne 
cette famille, j’étais disposé & lui venir en aide, et je lui aurais 
fourni les renseignements que l’expérience, mes relations, mes voy- 
ages et mes recherches assidues m’ont procurés. 

Sachant les matériaux que j’ai réunis sur ces insectes, M. Thom- 
son m’avait bien proposé d’imprimer en commun, un catalogue des 
espéces décrites. J’aurais accepté de grand coeur cette ceuvre utile ; 
mais je connais ses idées préconcues relativement 4 certains noms 
qwil veut abolir, et j’ai préféré m’abstenir ; je donnerai le mien 
quand mon ami et savant collégue M. le Professeur Th. Lacordaire 
aura revisé cette famille.

* J’ignore le motif de l’animosité passionnée de M. Thomson envers M. Pas- 
coe, qui sans doute expose d’une maniére souvent trop concise les genres et les 
espéces, sans indiquer leur place réelle, mais toujours est-il que j’ai reconnu la 
généralité des individus qu’il décrivait et qu’il n’en a pas été de méme de ceux 
de M. Thomson, bien qu’ayant connu quelques uns de ces derniers d’avance, j’ai 
eu quelque fois peine a les retrouver aux portraits qu’il a voulu en faire. Ses 
phrases sont longues, d’une structure inusitée, surchargées de répétitionsau fond 
réellement insuffisantes. Que M. Thomson prenne pour modeéle Gyllenhal et 
surtout Erichson concernant les Staphyliniens et ses Malachiens, il verra que dans 
un cadre restreint ces auteurs ont décrit tres minutieusement les espéces dont ils 
se sont occupés.

ront peut-étre, 4 cause des couleurs noire, jaune ou blanche, une 
division dans le genre Cyllene, et voici les motifs sur lesquels je 
m’appuie :— 

Pitces sternales composées comme chez le type; antennes munies

robe du Olytus Robinice ( flecuosus, F.). Ainsi, suivant M. Thomson, 
le grand genre Clytus des auteurs, qui, d’aprés un relevé récent que 
jai indiqué, contenait au moins 172 espéces, n’aurait plus aujourd’hui 
que ce seul représentant. Les auteurs en Europe n’admettront ja- 
mais ce changement. Si Fabricius a placé cette espéce en téte du 
genre, c’est qu’elle était alors une des plus grandes et des plus 
belles. Je doute qu’a cette époque, ot elle devait étre rare, il ait 
disséqué cette espéce pour caractériser son genre, tandisque tant 
d’autres communes du pays pouvaient remplir ce but.

Page 335.—M. Thomson tout en me remerciant des communica- 
tions que je lui ai faites dit aussitdt que je lui ai refusé, depuis, celle 
d’une quarantaine de genres appartenant aux Lamittes et aux Céram- 
bycites vrais, ce qui n’est pas enti¢rement exact. Si je lui ai refus¢é 
de les lui laisser casser comme cela avait eu lieu pour quelques Prio- 
nites dont il est loin d’avoir eu tout le soin possible. Cet auteur 
m’enyoya par la poste, une liste que je ne recus qu’un soir 4 8 heures. 
U0 fallait la lua renvoyer la lendemain matin méme, avec les espéces 
que je possédais. Je travaillai une partie de la nuit 4 annoter ces 
genres, et je lui écrivis ensuite que le lendemain devait étre employé 
par moi & assister 4 la cérémonie funcbre d’un proche parent ; que 
je Vengageais 4 venir chez moi, ou j’étais disposé & examiner avec lui 
les genres dont il s’agit ; ce n’était donc pas un refus de communica- 
tion: M. Thomson s’étant bien dérangé pour voir au Muséum de Paris 
certains genres qui n’existent que la, pouvait, ce me semble, dans 
Vintérét scientifique qu'il fait si souvent valoir, et s’il en sentait le 
besoin, faire ici une démarche analogue. 

Il continue et dit, pour la seconde fois, que ma collection est dans 
un ordre tel, que les moindres recherches doivent se payer non par 
des minutes, mais bien par des heures ! 

La collection de Longicornes de Dejean se trouve & peu prés dans 
Vordre ot il l’a laissée et telle que l’indique son Catalogue, les re-

cherches y sont done faciles. Quant aux espéces que j’ai obtenues 
depuis, et dont le nombre est, a la vérité, assez considérable, je les ai 
intercalées dans des boites supplémentaires ou réparties a peu pres 
4 leur place et dans les endroits bres. Cela ne comporte pas le dés- 
ordre qu’ indique M. Thomson, et les entomologistes peuvent se ras- 
surer sur les pertes de temps dont les menace M. Thomson. 

Ce systéme de dénigrement aurait en effet pour résultat, si je n’y 
répondais, d’éloigner de moi nos confréres et de diminuer beaucoup 
le prix de ma collection dans le cas ot je voudrais me dessaisir de 
quelques parties. Mr. Thomson a-t-il bien compris le tort moral et 
matériel que pourraient me causer ses attaques? j’aime a croire que 
non. 

Ma collection renferme tant de types cités dans les divers ouvrages 
entomologiques qui se sont publiés depuis 25 ans, que les lecteurs 
apprécieront, je pense, les observations qui précédent. 

La collection de M. Thomson est classée d’aprés les inspirations 
de sa nature pétulante, c’est & dire d’une maniére assez simple, mais 
peu scientifique. Il a adopté des étiquettes rondes de différentes 
couleurs qui sont percées par l’épingle d’une espéce pour désigner les 
différentes parties du monde; mais au lieu de prendre les couleurs 
géographiques comme Dejean l’avait fait et comme cela a été admis, il 
les a appliquées dans un sens opposé afin de n’étre pas taxé de routine. 
Un seul nom d’espéce se trouve inscrit sur chacune, avec rappel a la 
page de son ouvrage propre. Cette disposition produit exactement, 
dans ses boites, l’effet d’une distribution de pains 4 cacheter montés 
sur épingles. Voici une note assez curieuse de Vauteur et qui donne 
une idée de sa modestie :—‘‘ Les entomologistes feront bien a ’avenir 
de venir étudier leurs Cérambycides sur ceux de ma collection, qui 
offrent 4 la fois ces trois immenses avantages: 1° d’étre classés dans 
Vordre le plus convenable; 2° de constituer l’une des plus grandes 
collections de Cérambycides qui existent (3500 espéces) ; 3° d’avoir 
servi de base au travail actuel, le plus important qu’on ait encore 
publié sur les insectes en question.”

D’un fauve clair, couvert de petits points noirs ronds mais alongés 
et é6troits sur les étuis. Téfe en avant, plane, carrée, une bande jaune 
entre les antennnes et quatre lignes courtes, de méme couleur, sur le 
vertex, les deux frontales forment un trait circonflexe. Yeux noirs, 
entourés de jaune. Elytres arrondies et saillantes sur l’épaule, cette 
derniére offre une ligne de petits tubercules noirs; vers le milieu au 
dessous de la base se voit un tubercule noir; trois taches noires par 
étui, 1° au dela du milieu, transverse, oblique entourée de jaune; 
2° au dessous, située le long de la marge, allongée, également jaune 
sur ses bords; 3° ponctiforme, prés de la suture et en regard de la 
seconde. Abdomen ayant deux séries de points noirs, le dernier seg- 
ment en est privé. Sommet des jambes et les deux derniers articles 
des tarses noirs.

D’abord M. Thomson a passé sous silence les antennes, qui sont 
brunes. Elles ont le sommet des 3°, 4¢ et 5° articles d’un brun 
noiratre, avec le commencement de ces articles d’un gris rougeatre. 
Les élytres offrent en travers de la base un trait gris cintré qui s’ar- 
réte 4 l’épaule, et vers les $ postérieurs se détache une bande étroite, 
blanche, qui est pointillée de noir; l’espace qui existe entre cette 
bande et l’extrémiteé est d’un fauve clair cendré. De plus les tuber- 
cules noirs sont disposés en séries longitudinales au nombre de sept par 
étui, et la 2¢ série en partant de la suture, 4 sa naissance, est elevée, 
arquée avec les tubercules serrés, tandis qu’ils sont espacés ailleurs.

rectifie, comme il l’avoue 4 peu prés, pour un genre du groupe Ev- 
MOLPIDES, qu’il avait placé prés des Parménides. La composition des

mettre cette grosse erreur. 

On m’a appris derniérement que, en traitant de mon genre Agrius 
fallaciosus, dans sa monographie des Cicindélides, il m’avait horrible- 
ment maltraité en raison de la place que j’avais assignée a ce genre. IL 
savait cependant que ce n’était pas mon opinion personnelle que j’é- 
mettais. La place que je lui ayais d’abord assignée, mor, dans ma 
collection, et ot il reste encore, était justement celle émise par notre 
fameux critique. Il résulte de cette explication que l’indulgence en 
relevant des erreurs doit toujours étre gardée, puisque nous sommes 
tous exposés 4 nous tromper.

Cérambycides de M.Tuomson. Par H.Jexet. (Premier Article:

1. Genre Crytvs, Fabr. 


4 


Dans leurs louables efforts de chercher 4 retenir pour un groupe 
quelconque le nom des anciens grands genres linnéens ou fabriciens 
menacés de disparaitre, quelques entomologistes péchent, 4 mon avis, 
contre la logique, lorsqu’ils proposent de regarder comme type la 
premicre espéce décrite dans l’ouvrage ot ces genres ont été établis. 
Car, 4 ce principe, Fabricius, par exemple, aurait déji commis la 
premiére infraction, non seulement relativement 4 Linné, mais 4 lui- 
méme! Le genre Curculio avait pour chef de file une grande espéce 
exotique introduite par Fabricius dans son genre Calandra! 

On doit admettre que les eréateurs de l’entomologie, tous nés en 
Europe, ont eu plus particulicrement en vue, comme types de leurs 
genres représentés sur ce continent (et c’est l’immense majorité), des 
especes européennes. En effet, il est beaucoup plus naturel d’ad- 
mettre qu’ils ont été plus 4 méme de découvrir et de vérifier les 
caracteres sur des espéces dont les individus ne leur faisaient jamais 
défaut, lorsqu’il s’agissait d’en sacrifier pour l’étude de leurs organes. 
Enfin, c’est par les espéces de leur pays, continuellement 4 leur 
portée, qu’ils ont di étre impressionnés plus profondément, sur les 
rapports ou différences génériques., 

En placant leurs plus grandes espéces en téte de leurs genres, ils 
obéissaient tout simplement 4 ce sentiment de classification qui, sans 
tenir compte des analogies (conf. ‘ Fabricia Entomologica,’ i. 1, 4), 
placait le tambour-major et les grenadiers en téte de la colonne, 
subissant, involontairement, l’influence de la force, ou du moins, de 
ce qui semble la représenter par la taille. Mais le plus souvent ce 
n’était pas sur ces espéces que les caractéres génériques avaient été 
étudiés, comme il va étre démontré tout 4 Vheure. Je reviendrai 
plus tard sur cette question qui, relativement aux Curculio, devra 
étre prise en sérieuse considération, et j’aborde l’objet principal de 
cette note. 

Dans le cas actuel du genre Clytus, Fabr., qu’il ne s’agit pas ici 
de rétablir, mais bien de démembrer, genre si richement représenté 
en Europe, il me semble que 1!’on ne doit pas chercher son type dans 
une espéce de l’Amérique du Nord, quand le créateur du genre (né 
sur le continent qui a le droit de revendiquer pour ses espéces le 
maintien des noms établis par ses enfans) avait sous sa main un si 
grand nombre d’espéces de son propre pays, et lorsqu’il indique Iui- 
méme son type par la description détaillée des organes buccanx du 

VoL, I. U 


256 M. H. Jekel— Observations sur les 


Clytus arcuatus (Syst. Eleuth. 11. 347), qui cependant, dans cet 
ouyrage, n’est que la huitiéme espéce. 

Comment recevrait-on maintenant la proposition—en conséquence 
de la doctrine de M. Thomson—qui condamnerait le genre Carabus a 
étre réduit au Car. gigas (Procerus), Creutz., et quelques analogues, 
parceque cette espéce est la premiére dans le ‘Syst. Eleuth.,’ et qui 
descendrait l’immense nombre des especes européennes a l'état de 
sous-type (sous un nom nouveau !), lorsque Fabricius a indiqué son 
type par la dissection et la soigneuse description des organes buccaux 
de son Car. hortensis (nee Linné!)? Et lorsque cet auteur lui- 
méme a antérieurement et successivement placé en téte dudit genre, 
coriaceus (Syst. Entom. 1775), et mawillosus (Spec. Ins. 1781, et 
Entom. Syst. 1792), dont il forma plus tard (Syst. Eleuth, 1801) son 
genre Manticora, prouvant par 1a qu’il n’ayait jamais regardé sa 
premicre esp¢éce comme type! Je pourrais augmenter les citations, 
mais je crois celles-ci suffisantes et concluantes, pour maintenir a nos 
Clytus, les plus vrais entre tous, le nom qui leur appartient. Qu’on 
les subdivise en autant de coupes qu’on le jugera nécessaire, mais 
que le groupe dont l’arcuatus, Linn., Fabr.*, fera partie conserve 
ce nom! 

2. Sur les Couleurs géographiques @ Etiquettes. 


M. Chevrolat, en faisant allusion aux couleurs géographiques 
d’étiquettes ou paillettes, me semble y attacher une importance 
qu’une tradition trés limitée n’autorise pas. J’ai encore sous les yeux 
des étiquettes de diverses collections faites par des Francais qui 
avaient adopté des couleurs différentes de celles de Dejean. Les 
entomologistes anglais emploient aussi d’autres couleurs. Je n’ai 
pas remarqué quelles sont celles adoptées par M. Thomson, mais s’il 
a suivi en cela les propositions publiées par Haldeman‘, il a eu 
raison. car autant que je sache, c’est la seule proposition relative 4 
Varrangement des collections qui ait été faite d’une maniére aussi 
complete et raisonnée. En présence d’un travail publié et soigneuse- 
ment élaboré, toute tradition locale, 4 mon avis, devrait céder la place. 

En résumé, les couleurs adoptées par ce savant sont :— 


1. Amérique septentrionale . . . . . Bleu. 

2. Amérique méridionale. . . . . . Pourpre. 
SO: sUrOpeee eas SP MRE ET rel 3) SiR 

4. Afrique . . sien et test) ie ee OU ee 


* M. Chevrolat observe avec raison, 4 cet égard, que le genre Plagionotus, 
Muls., doit disparaitre et venir en synonymie.

cabinets,” &c., with a Map of the World. 


Cérambycides.—1. Lamiade. O57. 


5. Asie et Archipel Indien . . . . . Jaune. 

6. Australie et Polynésie. . . . . . Brun. 
Chacune de ces couleurs se subdivise en deux nuances, ou zones de 
latitude. 

Les couleurs sont en partie un peu trop dures, peut-étre, pour des 
étiquettes de fonds, généralement assez grandes, et l’on sait combien 
cela nuit aux insectes. Dans ce cas, l’étiquette blanche a bordure 
de couleur est préférable, ou bien encore une paillette ou bande 
latérale de couleur 41’étiquette fonds blanc. Mais pour les étiquettes- 
paillettes (comme celles de M. Thomson) ou toute autre attachée 4 
l’épingle, cet inconyénient disparait entiérement. 

Il serait temps que les entomologistes s’entendissent 4 ce sujet, 
ear ce langage muet, mais uniforme et expressif, rendrait de grands 
services dans les échanges et communications. J’ai quelquefois 
été bien embarrassé sur les provenances par des paillettes dont la 
couleur n’ayait un sens que pour la personne qui l’avait accollée & 
Vinsecte, bien qu’elle fut pénétrée de la suffisance de cette arbitraire 
indication de patrie. Et l’on sait, de quelle importance est l’indica- 
tion exacte de provenance pour la détermination d’espéces dans les 
groupes nombreux, sombres et unicolores, tels que les Harpalides, 
Cryptorhynchides, &e. 


3. Sur les Genres de Dejean caractérisés par M. Blanchard. 


Dans son ‘Essai sur les Céramb.,’ M. Thomson accompagne 
fréquemment son indication des genres Dejeaniens caractérisés par 
M. Blanchard dans son ‘ Hist. des Insectes,’ de l’expression ‘ sans 
citation d’espéce.’ Bien que M. Blanchard eut mieux fait sans doute, 
de citer une espéce décrite 4 l’appui de chacun de ses genres, il 
serait au moins spécieux de lui contester le droit de priorité 4 cause 
de cette lacune, car il est patent pour tous que toute espéce décrite 
faisant partie de ce genre Dejeanien s’indiquait naturellement comme 
type, par le simple renvoi au Catalogue Dejean, ainsi que le fait 
pressentir l’auteur dans sa préface (pag. v.). C’est plutét sur le 
laconisme de M. Blanchard qu’on pourrait élever des objections. 
Mais si l’on considére qu’une quantité de genres établis isolément, 
parfois plus briévement caractérisés—car il faut aussi tenir compte 
a M. Blanchard de ses subdivisions en tribus, familles et groupes 
caractérisés dans cet ouvrage d’ensemble, et qui réduisent de beaucoup 
le nombre de caractéres exigibles pour la distinction du genre—ont 
été reconnus et acceptés, quoique n’ayant pas toujours pour aider a 
leur reconnaissance la grande tradition Dejeanienne; on ne peut 
consciencieusement pas lui refuser ce qu’on a accepté de tant d’au- 
tres! Combien de genres Erichson lui-méme, dont on ne contestera 

v2 


258 M. H. Jekel— Observations sur les 


pas, j’espére, les soigneuses investigations et l’autorité, n’a-t-il pas 
earactérisés en quelques mots, également sans citation d’espéces 
décrites, et que bien des entomologistes ont su reconnaitre ? 

Le mal des descriptions trop bréves a existé, existe, et existera 
probablement encore aprés nous. S’y opposer de tout son pouvoir 
pour l’avenir, est chose digne—un devoir méme,—mais dans la dis- 
tribution des parts d’honneur du passé, ne faisons pas usage de deux 
poids et deux mesures! Et puisque dans le cas actuel, M. Thomson 
a su reconnaitre ces genres, qu’il rende franchement 4 César ce qui 
lui appartient ! 

4, Genre Atmopzs, Thoms. 

L’auteur a fait ici une grande confusion. Il donne d’abord comme 
synonyme de son genre (Archiv. Entom. i. 301) les Milothris de 
Dejean dont l’espéce typique Saperda marmorea, Sch. est connue de 
tous, mais qu’il ne cite pas. Mais il nous propose comme type de 
son genre une vraie Lamia de Fabr. 4 thorax épineux latéralement, 
qui n’a aucun rapport avec sa courte diagnose comparative, qui 
pourrait rehausser quelque peu la valeur de tradition, s’il citait le 
type de Dejean. 

Ensuite (Essai Céramb. p. 71), il ajoute une autre synonymie a 
ce soi-disant type, celle de la Saperda irrorata, Fabr. du midi de 
l’Kurope et de la Barbarie, espéce des plus connues. De sorte que son 
genre, en conséquence de ses trois citations, reposerait sur trois 
espéces appartenant a trois genres différents, et trés éloignés les uns 
des autres dans la classification. 

Bien que je ne prétende ici apprendre rien aux entomologistes 
versés dans la littérature et la synonymie, je ne crois pas inutile, 
néanmoins, de rappeler les trois espéces auxquelles les citations de 
M. Thomson nous renvoient : 

1. Lamia irrorata, Fabr. (nec irrorator, Thoms. Arch.) Entom. 
Syst. 11. 270, espéce de Lamiaire pr. d. 4 thorax épineux latérale- 
ment, et qui n’a rien de commun avec les Mélothris ni la diagnose 
de M. Thomson. 

2. Saperda iwrrorata, Fabr. Mant. i. 147. 4, Syst. El. ii. 319. 8, 
qui est notre espéce de l’Europe méridionale et du nord de l’Afrique 
(Agapanthia), citée par M. Thomson, comme je viens de le dire, en 
synonymie de la Lamia irrorata ci-dessus, et qui, comme elle, n’a 
aucun rapport avec les Milothris ni la diagnose des Atmodes. 

3. Saperda irrorata, Fabr. Syst. Eleuth. ii. 329. 65, dont le nom 
faisant double emploi dans le dit ouvrage, avec l’espéce plus ancienne- 
ment connue du ‘ Mantissa,’ fut changé par Schonherr (Synon. Insect. 
ii. 436. 105) en celui de marmorea, type du genre Milothris, Dej., 
mais que M. Thomson ne cite dans aucun de ses deux ouvrages ! 


Cérambycides.—1. Lamiade, 259 


5. Genre Hypsroma, Serv. 

Du moment que l’on propose le démembrement de ce genre, je 
crois qu’il serait de toute justice de retenir le nom de Hypselomus de 
Perty pour les espéces réunies par M. Thomson sous le nom de Cly- 
temnestra (Essai Céramb. 113), attendu que l’une de celles-ci, Clyt. 
tumulosa (Dej.) Thoms., n’est autre que Hypsel. cristatus, Perty 
(Delect. Anim. Art. p. 96, tab. 19. fig. 8), synonymie connue depuis 
longtemps des entomologistes. On pourrait, néanmoins, conserver 
le nom de Clytemnestra pour les espéces de la diy. B. de M. Thomson. 

Je posséde de ce genre un bon nombre d’espéces inédites (notam- 
ment de Cayenne, localité qui m’a fourni tant de nouveautés, ainsi 
qu’a mes correspondants), malgré celles déji nombreuses décrites dans 
les auteurs, Fabricius, Perty, Serville, Laporte, Blanchard, Erichson, 
Pascoe, et Thomson, dont plusieurs de ce dernier sont 4 retrancher. 

Aux observations synonymiques de M. Chevrolat (huj. op.), j’a- 
jouterai : 

subfasciata, Thoms,* (ligata, Chevr. MSS.) est lHypsel. crudus, 
Erichs. Archiv, 1847, 148. Cette espéce, dont habitat est trés 
étendu de l’est 4 l’ouest le long du fleuve des Amazones, de Cayenne 
et Para au Pérou, varie beaucoup pour la taille. 

La seule espéce de Fabricius rentrant dans ce genre, signalée par 
Erichson dans ‘ Schomb. Reise n. Brit. Guiana,’ est la Lamia globifera 
du Syst. Eleuth. i. 284 (Hypsioma tuberosa, Dej.), espece dont 
Vhabitat est également assez étendu—les Guyanes, le Brésil septen- 
trional, &ec., et qui varie aussi beaucoup pour la taille. Elle est le 
type dans ce genre d’une division signalée par M. Thomson (Essai 
Céramb. 115), et qui porte dans ma collection le nom de Jamesia.

XXII.—Tentamenta Entomologica. By H. Jexer, M.ES., &c. 


Havine been for some years engaged in the determination and 
classification of parts of Messrs. Bowring and Saunders’s Coleoptera, 
the careful study of these extensive collections, in connexion with 
my own, together with access to other important cabinets in London 
and Paris, has enabled me to determine many unsettled cases of 
synonymy, and to unite many natural groups confounded or dis- 
connected by various authors. 

The important collections received by Mr. Saunders from different 
parts of Greece (Athens, Albania, and Crete) would, if consulted, 
greatly increase the amount of our knowledge of that fauna, showing 
a fair addition of species, not only to the lists of Brullé* and Lucasf, 
but also to the more recent and highly interesting works of Reichef, 
Schaum, Kraatz, and v. Kiesenwetter$. 

Again, some important collections that I have received from 
Calabria, Sicily, Andalusia, Galicia, Portugal, and Algiers, have 
satisfied me of the absolute distinction and, on the other hand, the 
close affinity or even identity of numerous species with others col- 
lected in countries wide apart, viz. the south of France, Spain, and 
Portugal, with Greece, South Russia, Turkey, Anatolia, Caucasus, 
and Persia. 


Calathus circumseptus, Germ., and Calathus lateralis, Kiister. 


Having received many specimens of Calathus circumseptus, Germ., 
from Sicily and Algiers, I have been enabled to ascertain that Cal. 
lateralis, Kiist. (die Kifer Europa’s, xii. 34, 1848), is a mere variety 
of that species. The specimens from the above localities are gene- 
rally larger in size than those from the south of France; and it is 
only in specimens “ nuper exclusis,” or having a lighter coloration on 
the elytra, that these and the thorax seem to be proportionally 
broader and flatter, from the teguments not haying acquired their 
entire solidity and fulness of convexity, characters known to be 
shared by all “‘ nuper excluse”’ specimens. I have seen every inter- 
mediate in convexity and apparent breadth of thorax and elytra 
between the extreme Jateralis and the normal circumseptus, there-

fore Herr Schaum’s doubts on the value of Kiister’s species (cf. Catal. 
Coleopt. Eur. Berlin, 1859) were well founded. 


Acupalpus longicornis, Schaum. 

This little Acupalpus is one of the numerous instances of per- 
plexity and trouble in which the conscientious study of authors may 
place you. After having spent much time without ascertaining the 
specific name of my Consputus-like specimens, I had therefore con- 
cluded that they represented an undescribed species, which, although 
evidently allied to Schaum’s longicornis (Berlin. Entom. Zeitschr. i. 
145), could not be identified with his description*. Having by 
mere chance read that acute author’s new description of the same 
(Naturgesch. d. Insect. Deutschl. I. i. p. 622), (which is so different 
from the former, that, except the identity of the name, one would 
believe it quite another species,) I have just in time been enabled 
to withdraw my manuscript. 

The specimens under my inspection were caught in Albania 
by S. S. Saunders, Esq., and belong to Mr. W. W. Saunders. They 
are a trifle smaller, reaching not above 3} milliim. (=12 In. Par. 
mens.=11 lin. Angl. mens.). Their labrum is of a reddish hue, like 
the sides of the thorax, of which the red margin is well circumscribed, 
with the disk quite black, as well as that of the elytra, in which the 
large triangular humeral patch is, together with the narrow limb, of 
a well-defined pale-yellow hue. They quite agree with Schaum’s 
latter description, made upon mature specimens, and which alone 
applies to the species. 


Microtarinvs, Hochhuth, and Rhinocyllus Lareynu, Jacq. Duval. 


It is evident to me that Rhinoc. Lareynii, Jacq. Duv. (Ann. Soe. 
Entom. France, 1852, p. 714), belongs to the genus Microlarinus, 
Hochh. (Bull. Soc. Imp. Nat. Moscou, 1847, ii. p. 540). 

But the most interesting, as a geographical point, is its specific 
identity with Hochhuth’s Microl. rhinocylloides, of which I have no 
doubt, having carefully compared several extreme specimens of Rhin. 
Lareynit with the excellent description of the Russian author. 

This brings an addition to the genera of the European fauna ; 
the valuable characters pointed out by Hochhuth are most clear, 
besides a difference of habit which would destroy the homogeneity 
of Rhinocyllus. 

No doubt this species will be found along the zone extending be- 
tween these two extreme points, viz. Caucasus and South France ! 


* That description was very likely made upon immature specimens. 


M. H. Jekel—Tentamenta Entomologica, 265 


A second species belonging to this little group has just been 
described by Mr. Wollaston (Rhinocyllus lypriformis) in his most 
valuable paper “On certain Coleoptera from the Island of St. 
Vincent,” in Ann. & Mag. Nat. Hist. 1861. 

This increases the interest of the new generic form; and if we add 
that the typical species is also found in Egypt, we ascertain the wide 
range of the genus. 


Baranrnvs, Germ., Sch. 


This interesting and extensive genus, a great many of the exotic 
species of which are undescribed in collections, is principally com- 
posed of two very distinct forms, both represented in the European 
fauna. 

§ I. (Balaninus, pr. d.) 

The first, or Stirps I. (Genuini) of Sch.*, contains several types of 
large size, viz. :— 

Sect. 1. Hlephas, Sch., with aberrant species from Europe (Pellitus, 
Sch. ; Mastodon, Jekel, huj. op.) and America, readily distinguished 
by their more elongate, less conic, and more convex elytra. Nearly 
all the large and middle-sized North American species belong to this 
type. 

Sect. 2. Glandium, Marsh (= Venosus, Germ.), with the various 
forms and sizes of the continental specimens of the so-called Venosus, 
very likely forming two or three distinct species, forms an inter- 
mediate type in which the elytra, although much shorter and more 
conic,.are still convex as in the preceding section. Some of the 
North American species belong to this group. 

Sect. 3. Nucum, L.. Sch., and T'urbatus, Sch., represent another 
set of moderately large species, having broader, more conic and 
flattened elytra. This group, as regards its European species, must 
be entirely revised ; for, amongst the so-called specimens of 7’wrbatus 
from all parts of Europe, a good many have, in the construction of 
the external joints of the funiculus of the antenne, a tendency 
towards the incrassate and shortened shape declared by Schénherr 
and all subsequent authors to be peculiar to Nucum. The rostrum, 
especially in the 9 , is also subject to great variations in length, cur- 
yature, thickness, and sculpture. These differences, as far as I can 
judge from the materials I have at hand or have seen—the abnormal 
specimens being seldom from countries or parts thoroughly and con- 
tinually investigated by entomologists, but principally from remote 


* To the characters given by Schonherr, add: Unguiculi tarsorum basi intus 
aut angulatim aut subdentatim incrassati. 


266 M. H. Jekel—Tentamenta Entomologica. 


spots, whence we so often receive new species—may at least indicate 
local and permanent varieties, if not really distinct species*. But the 
question concerning such polymorphous species can only be settled 
by the study of an immense number of specimens from all parts of 
Europe. 

None of the North American species that I know of pertain to this 


group. 

Sect. 4. Villosus, F., Cerasorum, Hb., and Rubidus, Sch., are 
European species representing a group of a smaller size, having 
elytra short, conic, and rather flattened as in Group III. To this 
set belong a great many exotic species from Africa, India, and 
Australia, amongst which Melaleucus, Sch., is remarkable for its 
beauty and size, some specimens being larger than our Nucum. If 
Schénherr’s indication is not the result of an erroneous comparison, 
the species varies very much in size, for he says, “‘ Balanino villoso 
dimidio major.” This nevertheless would not be unlikely, for our 

European species present great differences in size. 

'  -'This*group might be subdivided into two sections according to the 
armature of the thighs; but Rubidus cannot be severed from Cera- 
sorwm in a natural distribution of the species, and some South African 


* Although, in a philosophical point of view, an important biological result 
will be attained by the recent conscientious and most valuable observations of 
Mr. Darwin (On the Origin of Species, &c., 1859) on the successive modifica- 
tions of species through the numberless influences acting upon successive genera- 
tions of a given type, descriptive zoology, restricted to the registration of the 
actual differences between actual species, regardless of the possible, but un- 
warrantable, modifications of such species a century hence, will probably always 
see its worshippers divided as to the limits of species or varieties. The more I 
have studied the matter, the more I have been convinced that nature, in the 
groups that we—more or less arbitrarily—call genera or subgenera, proceeds by 
types, round which actwal types (without regard to past or future modifications) 
gravitate the so-called species, subspecies (incipient species, Darwin), and varieties. 
It thus becomes every day more and more necessary for authors, monographers, 
or faunists to proceed, in their enumerations and descriptions, to philosophical 
and biological investigations of the really natural groups of species in each genus, 
and this is what I have aiways aimed at in my various enumerations of species 
in extensive groups. The continual and endless increase of materials in the 
collections makes it a duty to conscientious authors to follow such steps ; for the 
use of dry, short, aphoristic, and absolute descriptions (easy work !), giving no 
idea of the aberrant constitution of a new species, are the plague of science, 
especially when made by authors who have an insufficient knowledge of the 
various types of a genus. The excellent application of this principle by Mr. 
H. W. Bates (“Contributions to an Insect Fauna of the Amazon Valley,” in 
Trans. Entom. Soc. London, 1860 & 1861), enhanced by personal (ad naturam) 
investigations—inereasing so highly the value of philosophical deductions—de- 
serves the warmest thanks of all true entomologists. 


M. H. Jekel—Tentamenta Entomologica. 267 


present the same analogies*. The Catalogues of European Coleo- 
ptera would then arrange the species of this group as follows :— 
Balan. villosus, Fabr. 


cerasorum, Herbst. 
rubidus, Sch. 


§ IL. (Balanobius, Jekel.) 


The second large subdivision or Stirps IT. (Spuriz) of Schénherr 
should, according to the present ideas on generic characters, from the 
numerous and intrinsic differences it exhibits, be raised to the rank 
of a separate genus ; and I wonder at its having been overlooked by 
Mr. C. G. Thomson+, whose acuteness has supplied us with many 
new generic names in this and other families. This gentleman, in 
the Rhynchophori, has made use of several new characters, some of 
which, although deemed by him as primordial, should rather have 
been used as secondary, as they very often, even in his limited 
fauna, break palpable natural affinities, and consequently could not 
be rigorously applied to a general classification. 

This extensive subdivision of Balaninus may be distinguished as 
follows :— 

Antenne crassiuscule : articulis funiculi 4-7 latitudine haud longi- 
oribus; clava crassa, breviter ovata. Scutellum pro ratione minus, 
presertim brevius. Pygidium breve subtransversum, ab elytris con- 
junctim ad suturam parum emarginatis partim tectum. Unguiculi 
tarsorum angusti, basi non incrassati.— Obs. Corpus magis convexum, 
plerumque minoris magnitudinis. 

Besides a few European, it contains a great number of exotic 
species, most of which are South African, and only a few North 
American ; the exclusion of Pistor, Germ., rightly transferred by 
Schénherr to Centrinus, is, as regards its generic form, but one more 
instance of the necessity of reuniting all those Mecorhynchi having 
the pygidium partly or entirely exposed and more or less perpen- 
dicular. Regardless of the presence or absence of a tooth at the 
thighs (Manip. i. & 11. Sch.—a character of quite secondary value), 
it presents several natural types, of which two only occur in Europe : 
viz.— 

Sect. I. Containing: Cruz, Fabr. 
Ochreatus, Sch. 
Var. Rufosignatus, Fairm. 


* It is a fact that, by according the presence or absence of a tooth on the 
femora a primordial rank in the subdivisions of extensive genera, one very fre- 
quently destroys the natural affinities of species.

This lilliputian Balaninus, ranking amongst the smallest Curculio- 
nide, being only the size of Apion aciculare, Germ., is not yet recorded 
from Europe, although, as I have already said, it may be an inhabitant 
of South-eastern Europe (either Turkey or Greece). The three speci- 
mens upon which I found the species do not appreciably differ in 
size, while its congeners, Brassicw and Pyrrhoceras, vary very much 
in this particular. The unusual coarseness of the rugosities of its 
thorax, compared with its small size, distinguish it at once from 
Pyrrhoceras, with which only it can be compared. 


Genus Tycuivs, Sch. 


The rings of the abdomen in the Curculionide are very seldom 
exactly truncate at their apex, the first being most often emarginate in 
the middle, and 2-4 generally sinuate, 7. ¢. more or less roundly pro- 
duced in the middle, apparently emarginate each side of the latter, 
then more or less abruptly and obliquely produced downwards to the 
sides, where they form an acute angle with the side itself. This 
last character (often little evident, by the elytra embracing more or 
less of the sides of the abdomen) is highly developed in some groups 
(Cionina, Thoms. : Cionus and Nanophyes), but presents an anomaly 
in some species of the artificial genus Tychius of Sch. (Tychius pr. d., 
Stirps L., Sch., sp. 1-23), also in Miecotrogus and Sibynes, Sch.,= 
Tychiina, Thoms., loc. cit.* In most of these the second ring is so 
much produced that it covers nearly the whole of the side of the 
third ring (Tych. striatellus and Sibynes silenes, &c.), and often even 
reaches the base of the fourth (Tych. 5-punctatus, venustus, &c., 
Miccotr. cuprifer, picirostris, &c., Sibynes viscarie, &e.). In a few 


* Mr. Thomson says of his Tychiina: ‘“‘ Abdomen segmento 2° yentrali lateri- 
bus dentato-producto, basin 4! obtegente,” but this is exact for only a limited 
number of species. 


270 M. H. Jekel—Tentamenta Entomologica. 


others (T'ych. meliloti, &c.) the fourth ring is also more produced 
downwards than usually. 

This abnormal conformation of the second ring of the abdomen 
has led Mr. Thomson to the erection of a separate tribe as above re- 
corded ; but this characteris only applicable to Schénherr’s Stirps I., 
a few species of his Stirps II., and to Miccotrogus and Stbynes, which 
indeed, when reunited, form a very natural group. Schénherr’s 
Stirps IJ., based on the normal shape of the rostrum, “ Rostrum 
subtenue sublineare,” in opposition to Stirps I., ‘“ Rostrum basin 
versus crassius, apice attenuatum,” is heterogeneous, since it includes, 
as above said, some species (trivialis, Sch., auricollis, Sch., tebialrs, 
Sch., also amplicollis, Aubé) closely allied by their general consti- 
tution, the subsericeous tomentosity of their body, the shape of the 
second abdominal ring and of the tibie, &c., to Stirps I., although 
their rostrum be not exactly “apice attenuatum ” as in Miccotrogus. 
All the other species of Stirps II.—so far removed in their essential 
characters from Stirps I., and so wrongly intercalated by Schonherr 
and all subsequent authors between tomentosus, canescens, &ec., and 
cuprifer, picirostris, &c., all closely allied species—have their abdo- 
minal rings constructed after the normal type, and most of them 
bear a greater likeness to other groups of Erirhinide. The analogy 
of most of them with some species of the artificial genus Hrirhinus 
is so great, that Schonherr himself formerly ranked two South 
African species in that genus, retaining at the same time a variety 
of one of them with Tychius*. 

Entirely distinct from “ Tychiina,” as here restricted, the great 
majority of Stirps II. present the three following types :— 

I. (Typus I.). Scutello mediocri, conspicuo ; tibiis posticis (ut anticis) 
intus ad apicem aut angulato- aut spinoso-ampliatis, apice ipso unco 
horizontali aucto. Abdomen segmentibus ventralibus 2-4 utrinque 
paululum (A. e. normaliter) angulatim productis. Corpus squamis plus

brevibus, subzequalibus ; thorace valde ampliato; elytris brevibus a basi

modice ampliato ; elytris ovatis medio latioribus ; segmentis 2-4° abdo-

formes: (Styphlotychius, Jekel)—Typus: Tych. scabricollis, Rosenh.

Obs. I.—The characters given by Mr. Thomson to each of his three 
genera of Tychiina apply only to a limited number of European 
species. 

Obs. I1.—According to the artificial system of Schonherr, Tychius 
carinicollis, Lucas (=Aubeonymus pulchellus, Jacq. Duv.), from 
Algeria, South Spain (Cadiz), and Sicily, by the longitudinal channel 
of its prothorax beneath not extending further than the somewhat 
distant anterior coxz, strictly belongs to the second subdivision of 
the Cryptorhynchides, where it might be placed near Ocladius ; but 
I cannot see that it has anything to do with Hypsomus, as M. Jacq. 
Duval states; it rather resembles Pachytychius, with a tendency 
towards some species of Acalles.

Pachytychius elongatus, Sch. 


3. Rostro paulo breviore et crassiore, minus arcuato, lateribus magis 
ampliato.—Long. 53-7, latit. 21-25 millim. 


Pachytychius leucoloma, (De}j.) Jekel. 

This is evidently distinct from elongatus, Sch.; and Dejean had 
separated them in his collection. It is more than twice smaller 
(long. 43-43, latit. 1,3,-1,4, mill.). Rostrum proportionally longer 
and feaen: more nant Thorax much less transverse, evidently 
much longer, less ampliate at the sides, nearly subquadrate, with 
the punctures deeper, broader, much less numerous. Hiytra with 
deeper strive, coarser rugosities on the interstices. Body underneath 
much more coarsely punctate-rugose. 


The specimens from Algeria, which M. Lucas regards as belonging 
to Tychius elongatus, really constitute a distinct species, which I had 
long labelled in my collection under the name of 


Pachytychius Lucasii, Jekel. 

This species approaches nearer to leuwcoloma in size (although 
generally larger) and shape of thorax, but is readily distinguished 
from both species by having much shorter elytra; the antenne are 
thinner, and of a light rufous colour. In the configuration of the 
elytra it stands nearer to hematocephalus*, from which neverthe- 
less it is distinct by its less convex thorax, the broadest portion of 
which, as in the above two species, is much nearer to itsapex. Like 
the three species here mentioned its posterior thigh is dentate, but 
more obtusely. 

I have seen fresh $ specimens of 71 yeh. hematocephalus from the 
Basses Alpes which have the scutellum whitish squamose, like ru- 
briceps, Rosenh. Are the two distinct ? 


Sibynes sellatus, Lucas, from Algiers, is another species of this 
group, nearly allied to the four preceding, and having, like them, the 
elytra conjointly rounded at the apex, covering the pygidium entirely, 
and the posterior thighs obtusely dentate. It isa very pretty species, 
having the design of its elytra very similar to that of Baridius sellatus, 
Sch., from the same country. 


* T have seen small specimens of this species confounded with hematocephalus 
in some collections. 

+ The variable shape of the body and of the joints of the antenne in Tychius 
pr. d. (as I actually limit it) and in Szdynes reducing the number of their distinct- 
ive characters as established by Schonherr and subsequent authors, there remains 
only the difference in shape of the base of the thorax (sometimes very slight) and 
the more evident one of the apex of the elytra—viz. singly rounded, leaving the 
pygidium evidently exposed, in Sthynes—to distinguish the two groups.

Barytycuius, Jekel. 

The type of this little group, horde?, Brullé, varies considerably 
in size, coloration of the body, and density of squamulation ; its 
synonymy is also rather intricate. 

The normal colour of the body is black or pitchy, with rufous 
antenne and legs; but the head and thorax are often more or less 
rufescent, being in some small specimens even of a bright ruby hue. 
In some of the specimens with a light thorax, the usually black or 

x2 


274 M. H. Jekel—Tentamenta Entomologica. 


pitchy parts (rostrum, elytra, and body underneath) are either dark 
or light brown. 

The maximum amount of squamulation (which is whitish or 
flavescent) consists of two intra-lateral lines on the disk of the 
thorax, two entire longitudinal lines on each elytron (one dorsal, the 
other lateral), with the interspaces, especially at the base and apex, 
densely irrorate. But in many specimens the squamulation is re- 
duced to a short basal line on either side of the thorax, and to two 
short basal and apical lines on the elytra. The lateral line is gene- 
rally most persistent in intermediate specimens. Lastly, other 
individuals are quite destitute of squamosity. 

The punctures of the thorax also vary extremely. 

Its size varies between 21 and 33 millim., some being hardly 
longer (though broader) than T'ych. picirostris ; the largest equalling 
Tych. venustus. This variation of size occurs indiscriminately in 
every country in which it is found, viz. South France (Montpellier, 
Marseilles, &c.), Sardinia, Sicily, Crete, Anatolia, Syria, Caucasus, &e. 

The synonymy stands as follows :— 

Tychius hordet, Brullé, Expéd. Scient. Morée, Articulés, p. 246 (1882), 
1834. 
squamosus, Sch. Gen. et Sp. Curcul. ii. p. 419, 1836. 
alboguttatus, Redtenb., Russegger, Reise, i. p. 988, 1843. 
—— intramarginalis, Hochhuth, Bull. Soc. Imp. Nat. Mose. 1847, ii. 

p. 549. Since recognized by the same as 
squamosus, var. Caucasicus, Hochh. loc. cit. 1851, i. p. 94. 

The correct and minute description by Hochhuth helps greatly in 
the recognition of the species, when found in our western countries. 

Through its immersed scutellum, this group should be ranged near 
Tanyrhynchus and Trachodes, waiting the production of a general 
classification based upon natural affinities and embracing the various 
forms of the whole world. This gigantic work, undertaken by Prof. 
Lacordaire’s master hand, we most anxiously expect. 

Tychius amenus, Say, Sch., possibly belongs to this group. 


SrypHiorycutius, Jekel. : 

This group should also be transferred to the subdivision Erirhi- 
nides exscutellati of Schonherr. It bears a certain likeness to the 
Styphlide and to Trachodes. 

Besides its type, Tychius scabricollis, Rosenh. (die Thiere Anda- 
lusiens, p. 280)=asperatus, Dej. Catal. =nitidirostris, Dufour in litt., 
which is widely distributed in South-western Europe, I have seen a 
few more species, which unfortunately are not at the present time 
within my reach.

Type, Macrolema vittata, Baly. 


This striking genus stands in close proximity to Brachydactyla, 
Lac., agreeing in having a distinct prosternum and in not possessing 
conical anterior coxee, but differing in the third and fourth joints of 
the tarsi being formed in accordance with the ordinary type of the 
family, and in the anterior cox being transverse instead of hemi- 
‘spherical. From all the remaining genera, the transverse anterior 
coxee and (Megascelis and the first section of Crioceris excepted) 
the possession of a prosternum separate it. 

The beautiful insect on which the genus is founded has been 
recently sent by Mr. Diggles from Dawson’s River, a new settle- 
ment in the northern part of Queensland, Australia.

three times its length, sides parallel, above very convex, gibbous at the 
base; each elytron covered with about ten ill-defined interrupted rows 
of large deeply impressed punctures, the interspaces thickened; the 
piceous patches, the most considerable of which occupies the middle

Hab. China. 

Very similar to the preceding species, but differmg in the greater 
length and in the form of the antennz, in the longer body, and in the 
entirely different arrangement of the punctation of the elytra. Head 
rather shorter than in C. Dromedarius; antennee longer than half the 
body, robust, subfiliform, indistinctly incrassate towards the apex ; four 
or five terminal joints slightly incrassate, second, third, and fourth joints 
short, submoniliform. Thorax equal in length, but more regularly con- 
stricted on the sides, the constriction commencing at the angles and 
extending the whole length of the side; in the other species the con- 
striction commences a short distance from the angles, and is more 
abrupt; disk impunctate, with the exception of a double longitudinal 
row of very fine punctures down the middle. Elytra oblong, parallel ; 
the gibbosity slightly less raised than in the former species ; the punc- 
tures on the surface as large and as deeply impressed, but arranged in a 
different manner ; the strize from being more interrupted are less distinct, 
and in addition the whole inner disk, from the base of the gibbosity 
nearly to the apex of the elytra, is entirely free from punctures; the 
punctures here and there confluent. Thighs similar to those of C. 
Dromedarius ; body beneath sparingly covered with pubescence.

Type, Rhyparida dimidiata, Baly. 

Rhyparida forms one of a group of genera (many as yet unde- 
scribed) possessing in common a notch on the outer edge of the four 
hinder tibize, near their apex. They may be divided into two sec- 
tions, viz. one in which the claws are toothed, and a second in which 
they are simply appendiculated; of the first section, to which Rhy- 
parida belongs, Typophorus is, I believe, hitherto the only cha- 
racterized genus. Rhyparida (the species of which are natives of 
Australia and the Eastern Archipelago) differs from the above- 
named in the transverse thorax and in the different form of the 
antero-lateral plate of the antepectus: this part in the older genus 
has its anterior margin convex, and produced beyond the border of the 
thorax; in the present the same margin is oblique, and not ante- 
riorly produced.

Narrower and more elongate than the preceding species ; in sculp- 
ture, form of head, &c., precisely similar. The colouring of the 
elytra appears to be very variable: the individual from which the

but a specimen in the possession of Mr. Janson has the green por- 
tion of the elytra sparingly covered with adpressed silvery hairs.

This genus can be at once separated from congeneric forms by the 
remarkable 12-jointed antennie, the joints themselves presenting 
such strange contortions that it is almost impossible to describe 
them. I must therefore refer to the figure in Plate XII. for a more 
correct idea of their form. 


Xenarthra cervicornis. (Plate XII. fig. 4.) 


X. elongata, sat angustata, pallide flava, nitida; antennis difformibus, 
nigris; capitis thoracisque lateribus, metasterno, abdomine (baseos medio 
excepto) tibiisque posticis (his basi exceptis) piceis; elytris obsolete 
costatis, fortiter subcrebre punctatis, viridi-zeneis.—Long. 3 lin. 

Hab. Ceylon. 

Head strongly exserted; eyes prominent; face above the antennz 
furnished with a triangular elevated space, divided longitudinally by a 
medial groove, the apex of which terminates in a deep fovea; antenns 
rather longer than the body, 12-jointed, the twelfth articulation being 
formed, by the separation of the false joint visible in nearly all Phy- 
tophagous insects at the apex of the antenn, into a distinct piece. 
Thorax one-third broader than long, narrowly margined, sides nearly 
parallel, slightly produced and angled in the middle; upper surface 
slightly convex, smooth, impunctate, impressed behind the middle 
with two large and deep parallel foveze. Scutellum trigonate, its apex 
acute. Elytra rather broader than the thorax, parallel, moderately con- 
vex, deeply punctured, each elytron with five or six indistinct longi- 
tudinal coste. Legs slender; tarsi stained with fuscous. 


Genus STENOPLATYS. 


Corpus subelongatum. Caput exsertum ; antennis gracillimis, filiformibus,

Pedes graciles, simplices; coxis anticis contiguis, perpendicularibus ; 
unguiculis appendiculatis. 

Type, Stenoplatys Pascoei, Baly. 


The general form of the body resembles Aplosonyx ; but the en- 
tirely different antenne at once separate Stenoplatys from that genus. 


Stenoplatys Pascoei. (Plate XII. fig. 5.) 


S. subelongata, modice convexa, pallide flavo-fulva, nitida; antennis

narrowly margined, straight and nearly parallel, obtusely angled just 
before the middle, thence obliquely narrowed to the apex, all the angles 
prominent; disk minutely punctured, impressed with three large shallow 
fovere. Elytra much broader than the thorax, oblong, parallel, their 
apex rounded, above moderately convex, impressed longitudinally along 
the suture, and transversely below the basilar space, the two depressions 
forming a large common cruciform fossa, the suture itself indistinctly 
costate ; basilar space on each elytron obsoletely elevated; on the outer 
disk, a short distance below the transverse groove, is a large shallow fovea. 


Genus Prasona. 


Corpus elongatum, modice conyexum. Caput porrectum; antennis fili- 
formibus, apicem versus attenuatis, articulo primo incrassato, subclayato, 
secundo brevi, obovato, tertio duobusque proximis singulatim secundo

Var. A. Elytris immaculatis. 

Hab. Mexico. 

Elongate, moderately convex. Face trigonate, elevated between the 
eyes, upper portion of the raised space impressed by a longitudinal 
fovea; vertex finely but remotely punctured. Thorax nearly twice

perfect, that it is impossible to recognize the species without a refer- 
ence to the original specimen. 


Crioceris Sallét, ante, p. 195. This species possesses a distinct 
prosternum, and therefore ought to be placed in the Ist section of 
the genus. 


XXIV.—Entomological Notes. By Francts P. Pascor, F.L.S. 


1. Havine recently seen a specimen of Merywx rugosa, Latr., in 
Melly’s collection at Geneva, I at once identified it with my genus 
Rhyssopera (ante, p. 98), probably R. illota. The habitat given by 
Latreille, ‘in India orientali,” is doubtless a mistake. In my 
description, the tarsi, by a lapsus calami, are described as five-jointed ; 
they are, however, only four-jointed, as may be seen by the naked 
eye, and the genus must therefore be ‘ technically’ referred to the 
Colydiidee. 

2. Gleania ulomoides (ante, p. 100) is an Aulonium belonging to a 
section of that genus, the species of which are found from Brazil to 
Mexico, and represented by Colydium bidentatum*, Fab. The minute 
basal joint described by me appears to be only the deeply constricted 
portion of the articulation of the joint. 


3. The genus Althesia (ante, p. 117), Mr. Janson suggests, should 
probably be referred to the Endomychide. As in any case the genus 
approaches Mycetwa, which is referred to the Mycetophagidee by Mr. 
Wollaston, and by M. Jacquelin Duval is made the type of a distinct 
family in immediate sequence to it, the position I have assigned 
it may be considered as dependent upon the views which may be 
ultimately taken of Mycetea. 


4, Hvethis and Anomesia, referred as synonyms to Frivus, Thoms., 
by M. Chevrolat, at p. 190 of this Journal, must all give way to 
Eunidia, Erichs., as I have already stated in the Proc. Ent. Soe. 
July 1859. 


5, At p. 192 of this Journal, M. Chevrolat gives Cylindrepomus, 
Pascoe, as a synonym of Gerania, Serv. In the first place, Cylin- 
drepomus is a genus of Blanchard’s; and secondly, it is altogether 
very different from Gerania. 


* I have nine species in my collection, to any of which the Fabrician deserip- 
tion is applicable.

areolet extremely long, with two approximate oblique veinlets at its tip. 


This genus may be distinguished from Dichoptera by the structure 
of the legs, wherein it has some affinity to Poiocera obliqua; and the 
latter should form a new genus. 


Hesticus pictus (Pl. XV.f. 5). Mas. Rufescens; caput pallide viride, 
yerticis disco luteo, fronte supra nigra lateribus albis, facie supra lete

apex; antenne as long as the breadth of the head behind, the first 
joint punctured, the rest glabrous with a few hairs only on the club ; 
prothorax shining black with the anterior angles obtuse, the sides 
rounded rapidly to the base, the posterior angle nearly obsolete, covered 
with oblong punctures, those at the side only granulated; scutellum 
transverse, with 6-8 punctures in two rows; elytra dull black, seriate- 
punctate, the punctures coarse, oblong, and in double lines, the inter- 
vals smooth, and slightly elevated ; femora and tibiee simply punctured ; 
body beneath pitchy black with granulated punctures. Length 7 lines. 


Melambia memnonia. 


M. subelongata, atra; prothorace transverso, disco subplanato, antice 
incrassato, basi lata, angulis posticis acutis ; elytris obscure fuscis. 
Hab. Ceylon. 

Subelongate, black; head covered with rather closely set, oblong, 
granulated punctures, mandibles with small simple punctures extend- 
ing to the bifid apex; prothorax black, slightly shining, punctured as 
on the head, but less closely, and the punctures with granulated bases 
confined to the sides, anterior margin thickened immediately above the 
vertex, the disk flattened behind the thickened parts, side slightly 
rounded, then shortly curving inwards, and terminating at a sharp 
angle in a broad base; scutellum transverse, with eight or ten scattered 
punctures; elytra opake, nearly black, with a slight chestnut-brown 
tinge, punctured in double rows, the outer row with its punctures 
about a third or a fourth of the size of the inner, which latter are more 
or less impressed on the side of the raised lines between the rows; legs 
pitchy, the femora and tibize punctured ; body beneath, under side of 
the mandibles, and palpi reddish-pitchy, the former with scattered 
punctures, each nearly entirely occupied by a smooth granule. Length 
6 lines. 


In the form of the prothorax this species approaches WM. gigas, 
Fab., and apparently also MW. striata, Or., both from Senegal ; but 
the former is larger and more robust, with bluish-black elytra, &c., 
and the second is distinguished by its more punctured and remark- 
ably transverse scutellum, &c. MM. crenicollis, Guér., from India, 
seems to be a smaller species with a differently shaped prothorax, 
with its sides sufficiently crenated to suggest the specific name. 


Melambia funebris. 


M. subelongata, obscure atra ; prothorace transverso, disco leviter convexo, 
basi sublata, angulis posticis acutis. 
Hab. Cambodia. 
Very like the last, but differs-in the following particulars: prothorax 
longer, more rounded at the sides, and more contracted at the base, 
slightly but regularly concaye over the whole disk, the anterior margin 


Genera and Species of Coleoptera. 321 


not in the least thickened ; elytra with the lines between each double 
row of punctures more raised, the punctures (more nearly equal in size) 
and the lines themselves gradually disappearing towards the shoulder; 
colour a dull black, without any tinge of brown. 


Itis quite possible that this may be only a local variety ; but, with 
the members of a genus so closely allied as they are in Melambia, 
this cannot be assumed until we obtain intermediate forms. 


Bronres [Cucujide ]. 


Fabricius, Syst. Eleuth. ii. p. 97. 


Brontes lucius. 


B. ferrugineus, setulosus; prothorace lateribus denticulatis, dente antico 
incrassato ; elytris striato-punctatis, marginibus infuscatis. 
Hab. Sydney. 

Ferruginous brown, covered with short, dark, setulose hairs; head 
rather exserted, the vertex somewhat depressed; eyes dark brown; 
antennz longer than the body, with a slight greyish pubescence, the 
first joint nearly as long as the four next together; prothorax rather 
broadly elongate, covered with numerous large shallow punctures, the 
sides denticulate, the anterior angle occupied by a strong triangular 
tooth; scutellum transversely pentagonal; elytra closely punctate- 
striate, becoming gradually darker towards the sides; legs pale ferru- 
ginous; body beneath dull ferruginous, closely punctured. Length 4 
lines. 


Brontes nigricans. 


B. fuseus; prothorace lateribus denticulatis, dente antico incrassato ; 
elytris striato-punctatis, nigricantibus. 
Hab. Queensland (Moreton Bay). 

Dark ferruginous brown, covered with short, black, setulose hairs ; 
head slightly exserted; eyes dark brown; antenne longer than the 
body, the first joint shorter than the four next together; prothorax 
broadly elongate, rugose, slightly punctated, the sides equally denticu- 
late, the anterior angle occupied by a moderately thickened tooth ; 
scutellum transversely pentagonal ; elytra punctate-striate, of a uniform 
dark brown; legs ferruginous; body beneath dull ferruginous, closely 
punctured. Length 4 lines. 


From Brontes denticulatus, F. Smith (also from Australia), the 
two species described above differ in the comparatively elongate, not 
transverse, prothorax and other characters. Brontes militaris, Er., 
is smaller and less robust, narrower prothorax, differently coloured, 
differently punctured, &c.

Ino [ Cucujidee ]. 
Laporte de Castelnau, Etud. Entom. p. 135. 
Ino ephippiata. (Pl. XVI. fig. 9.) 


T. nigra, nitida; elytris disco pallide flavescente, abdominis segmenta 
tria ultima haud obtegentibus. 
Hab. Dorey (New Guinea). 

Deep glossy black ; head and prothorax about equal in breadth, finely 
punctured, the latter very much contracted at the base; antennz half 
as long as the body, black, the basal joints paler; palpi pale brown ; 
scutellum black, transversely ovate; elytra narrowed at the base, 
gradually widening posteriorly, where they are as broad as long, the 
sides straight, the disk with a large pale-yellow spot occupying nearly 
the whole of the base, except the shoulder, and expanding below the 
middle towards the side; part of the third and fourth and fifth abdo- 
minal segments dull black, not covered by the elytra; legs light glossy- 
brown, tarsi testaceous; body beneath paler. Length 1} line. 


Ino trepida. 

I. fusca, nitida; elytris singulis flavescente unimaculatis, abdominis seg- 
menta quatuor ultima haud obtegentibus. 

Hab. Dorey (New Guinea). 

Dark olivaceous brown, shining; head and prothorax equal in breadth, 
finely punctured; antennze about one-third the length of the body, the 
two basal joints yellow, the remainder black; scutellum and elytra as 
in the last, but the yellow spot on the latter is smaller, nearly round, 
and situated below the middle and towards the outer margin ; abdo- 
men dark brown, shining, the last four segments not covered by the 
elytra; legs olivaceous brown, the tarsi paler, inclining to testaceous. 
Length 13 line. 

Ino is a very singular genus, and was placed by M. de Castelnau 
among the Staphylinide, after Anthobium. The species described 
by him (J. picta) from Madagascar has slightly elevated lines on the 
elytra, and it is possible that the two described above may hereafter 
form another genus. 

Puenace [ Dasytidee |. 

Head short, rounded in front, the epistome and lip concealed beneath its 
margin. Eyes large, prominent, entire. Antenne filiform, distant, 
arising below the eyes, the first joint rather short, obconic, the second 
very short, the remainder to the tenth longer and subequal, the last 
longest of all. Maxillary palpi long, the terminal joint fusiform. 
Mandibles long, slender. Prothorax rounded at the sides. Elytra 
broader than the prothorax, elongate. Legs slender; tibize spurred ; 
tarsi very long, the basal joint longer than the second. 


In general appearance this genus has a wonderfully striking re- 


Genera and Species of Coleoptera. 323 


semblance to some of the Gidemeride ; its very distinctly five-jointed 
tarsi, however, independently of other characters, show at once that it 
can have nothing to do with that family. But there can be no hesita- 
tion, I think, in referring it to the Dasytide, notwithstanding the 
structure of the mouth and the presence of two well-marked spurs 
to the tibise: in regard to the first, the lip and epistome are so com- 
pletely hidden by the scarcely prolonged anterior margin of the head, 
that, without dissection, their existence can only be assumed ; be- 
tween this margin and the mandibles there intervenes a sort of 
cavity, and the latter, not being covered in the usual way by the lip, 
are fully exposed almost to their base. My specimen, which is 
unfortunately, I believe, unique, was taken by the well-known 
traveller Anderson, in Southern Africa, in the country near Lake 
N’Gami. 

Phenace edemerina. (Pl. XVI. fig. 6.) 
P. gracilis, fuscescens, parce pilosa; scutello elytrisque pallidioribus. 
Hab. N’Gami. 

Slender, dark olivaceous brown, sparsely clothed with rather long, 
pale-greyish hairs; head and prothorax shining, dark brown; scutellum 
elongate, rounded below, a depressed longitudinal line in the middle ; 
elytra narrow, elongate, nearly parallel, the shoulders rather prominent, 
substriate, olive-brown, paler as it recedes from the base ; mandibles 
bright ferruginous; legs reddish brown; body beneath dark brown, 
hairy. Length 33 lines. 


Ocnotyra [ Lampyride]. 

Head partially exposed, short, broad in front. Eyes very large, contiguous 
beneath, constricted behind, Antenne very short, 12-jointed, the two 
basal thickened, the rest serrated. Prothorax transverse, narrower 
than the head. Elytra broader than the prothorax, subparallel, shorter 
than the abdomen. Legs moderately short, all the coxze nearly con- 
tiguous; tarsi slender. Abddmen eight-jointed in the male, the joints 
gradually decreasing in breadth to the apex. 

This genus is allied to Dioptoma (ante, p. 118), and the nearest 
affinity of the two is apparently with Luciola, Lap. (Colophotia, 
Dej.). In the only example I have seen of the former the abdomen 
has been removed, but, judging it from what we now see of this, it 
is probably also exserted, with the same number of segments—the 
normal number, in fact, in the males. The females of both are un- 
known. 

Ochotyra semiusta. (Pl. XVI. fig. 7.) 

O. pallide fulva ; capite prothoraceque piceo-fuscescentibus. 

Hab. India (Malabar). 

Pale fulvous yellow, very sparsely covered with greyish appressed 
hairs; head pitchy-brown, concave between the eyes, epistome with 


324. Mr. F. P. Pascoe on some new or little-known 


stiff greyish hairs; antenns not extending beyond the eyes, pale 
yellow, strongly serrated, broadest in the middle; -eyes dark brown, 
shining; prothorax light pitchy brown, darker on the disk; scutellum 
rather large, triangular; elytra about twice the length of the head and 
body together, depressed, and almost concave posteriorly, with elevated 
nervures in the middle, 7. e. not extending to the base or apex ; legs 
clothed with stiff hairs, particularly on the tibie; abdomen dull 
whitish yellow. Length 4 lines. 


In the Plate the figure of this species is longer than it ought to be. 


Eruas [Tenebrionide ]. 

Head elongate, broader than the prothorax, rounded and dilated anteriorly, 
narrowed into aneck behind. Eyes remote from the prothorax, lateral, 
partially divided posteriorly. Mentum somewhat pentagonal, narrow 
at the base, concealing the labium. Maxillary palpi robust, the ter- 
minal joint subcylindric, of the labial ovular. Antenne stout, eleven- 
jointed, the first largest, the second shorter than the third, which, with 
the remainder to the tenth inclusive, are transverse and cup-shaped, the 
eleventh small, shortly cylindric. Prothorax sulcated, subquadrangular, 
broadest in front, the anterior angles rounded, the sides keeled. Elytra 
elongate-ovate, wider than the prothorax, ribbed. Legs robust; femora 
slightly clavate ; tibie not spurred; tarsi ciliated beneath ; prosternum 
produced, rounded anteriorly. 


The ribbed prothorax and elytra will at once distinguish this genus 
from Stenosis, which has exactly the same habit. The structure of 
the mouth varies a little from that genus, in Hthas the large angular 
mentum filling up more of the oral cavity, and entirely concealing 
the labium. 

Ethas carbonarius. (Pl. XVI. fig. 2.) 


E. niger, subnitidus; prothorace leviter trisulcato; elytris singulis lineis 
quinque elevatis instructis. 

Hab. Malabar. 

Punctured, black, slightly shining ; head convex between the eyes, 
with three rather shallow grooves, and on each side a somewhat deeper 
groove in which the eye is placed ; prothorax alittle narrower than the 
head, marked with: three lightly impressed lines or grooves, the spaces 
between, especially the two middle, slightly elevated and convex; scu- 
tellum punctiform; elytra scarcely wider than the prothorax at its 
base, each with five narrow elevated lines rather thickened at the 
suture, but scarcely forming another; legs slightly pitchy ; palpi ferru- 
ginous; body beneath black, shining, sparingly punctured. Length 4 
lines. 
Ethas stenosides. 

E. niger, subnitidus; prothorace profunde trisuleato; elytris singulis 
lineis quatuor eleyatis instructis. 

Hab, Siam. 


Genera and Species of Coleoptera. 325 


Punctured, black, slightly shining; head very convex between the 
eyes, not sulcated; prothorax much narrower than the head, only 
slightly dilated anteriorly, with three broad and deep longitudinal 
grooves, the spaces between sharply elevated (with the keeled sides 
forming altogether four narrow but prominent cost); scutellum small, 
triangular ; elytra broader than the prothorax at the base, each with 
four raised lines, the two central abbreviated towards the apex, the 
suture not thickened; legs pitchy; body beneath black, sparingly 
punctured; antennz, especially towards the apex, sparsely clothed 
with rich golden-brown hairs. Length 22 lines. 


Smaller and proportionably narrower than the last, and readily 
distinguished by a multitude of characters, although the habit is 
nearly the same. 


Aposyta [Tenebrionide. | 


Head convex and subtriangular in front, slightly elongated behind the 
eyes. Antenne short, eleyen-jointed, gradually increasing from the 
base, the first joint partially concealed by the antennary orbit. Eyes 
large, round, entire. Epistome and lip short, very transverse. Palpi 
with the terminal joint narrowly triangular. Mentum transverse. 
Prothorax subcordate, scarcely longer than broad, Elytra narrow, sub- 
parallel. Legs moderate ; anterior coxe large, subcylindrical, greatly 
exserted ; tibize spined ; tarsi slender. 

But for the large and greatly exserted anterior coxe, I should not 
hesitate to place this genus near Calcar, although the antennary 
orbit is so contracted as to leave the eye perfectly free, and the 
epistome, although short, is of great breadth and apparently distinct 
from the front. Whatever its affinities may be, I cannot myself see, 
at present, that it can be better placed than near Calcar and Boros. 


Aposyla picea. (Pl. XVI. fig. 4.) 


A, subelongata, rufo-fusca, nitida, punctata; antennis ferrugineis. 
Hab. Queensland. 

Rather elongate, subdepressed, shining, reddish brown; head convex 
between the eyes, and slightly constricted behind them, irregularly punc- 
tured ; antenne ferruginous; lip with stiff greyish hairs; prothorax 
with numerous somewhat coarse punctures; scutellum broadly trian- 
gular; elytra scarcely wider than the prothorax, punctured in rather 
irregular rows ; body beneath and legs reddish-brown. Length 33 lines. 


Raypasma [Tenebrionide ]. 


Head rather broad, convex in front, truncate anteriorly, the epistome and 
lip inserted beneath. Eyes small, oblong, entire. Antenne 11-jointed, 
inserted beneath the broad antennary orbit, half the length of the body, 
the first three joints longer, the next five submoniliform, the last three

forming a narrow club. Mentum large, transverse. Prothorax longer 
than broad, subquadrangular, narrowed behind, sinuated in front, longi- 
tudinally sulcated. Elytra subdepressed, carinated, scarcely broader 
than the prothorax, and slightly rounded at the side. Legs rough, 
moderately robust; tibiee fusiform; tarsi narrow; the claw-joint as 
long as the rest together; pro- and mesosterna simple; post-intercoxal 
plate broadly truncate anteriorly. 


Notwithstanding the small size of this insect compared with 
Zopherus and Nosoderma, there can be little hesitation, I think, in 
placing it near those anomalous genera. Judging from the exami- 
nation of the oral organs made in situ, they appear to offer only a 
slight modification of those of Nosoderma, the mentum, however, 
being considerably larger and in great measure hiding the palpi and 
base of the maxillex, the part between its lateral margin and the 
insertion of the antenna offering a deep cavity, as in that genus, for 
the reception of its basal joints when that organ is in repose. The 
propectus has no antennary canal at its side as in Zopherus, in this 
respect agreeing better with MNosoderma; on the other hand, the 
latter has only a ten-jointed antenna, but this is again modified by 
the fact that VV. obcordatum, Kirby, has eleven. 


Rhypasma pusillum. (Pl. XVI. fig. 3.) 


R. obscure testaceo-brunneum ; prothorace trisulcato ; elytris disco tricos- 
tatis, costa intermedia abbreviata. 
Hab. Para. 

Dull testaceous brown, more or less sprinkled with a semicrystalline 
exudation? head with numerous small granules, and having the 
appearance of being originally covered with an earthy crust; antennz 
covered with granulations, each tipped with a fine hair; prothorax 
with two curved longitudinal costz on the disk, nearly meeting ante- 
riorly, the lateral margins flattened and resembling the coste, and like 
them crested with a number of small closely set granules, the spaces 
between the costz and the margins respectively forming three broad 
shallow grooves; scutellum transverse, subquadrate ; elytra rounded at 
the shoulder and at the apex, the disk with three strongly crenulated 
coste, the outer and inner united near the apex, the intermediate 
ceasing at two-thirds the length of the others, the external margin also 
forming a crenulated border, resembling the coste, the spaces between 
deeply and coarsely punctured; legs covered with small asperities and 
cilia ; body beneath rufous-brown, covered with numerous granulations. 
Length 2 lines. 


With reference to what is probably an exudation (renewable 
perhaps at the pleasure of the animal), it has the appearance under 
the microscope of small particles of brown sugar.

Westwood, Are. Entom. i. p. 43. 


Chartopteryx binodosus. 
C. obovatus, fusco-cupreus; elytris basi bigibberis. 
Hab, Queensland. 

Obovate dark copper-brown, irregularly punctured with numerous 
nearly erect hairs arising from the punctures; head with a transverse 
impression above the epistome, roughly but rather sparingly punctured ; 
antenne black, not reaching beyond the base of the prothorax, the four 
terminal joints dilated ; prothorax transverse, sinuate in front, anterior 
angles produced, the posterior rather acute, with shallow scattered 
punctures; scutellum subtriangular; elytra very convex, a large com- 
pressed elevated protuberance near the base of each, rather dilated, 
posteriorly covered with large rough punctures; legs hairy; body 
beneath less coppery and more slightly punctured, with fewer hairs. 
Length 5 lines. 


This species differs considerably in habit from C. Childreni, West., 
and in that respect bears a marked resemblance to T’hecacerus bino- 
dosus, Lap., belonging to the same family. It may be necessary 
eventually to propose a new genus for its reception.

Westwood, Arc. Entom. 1. p. 43. 


Cyphaleus insignitus. 
C. ovatus, niger, subnitidus ; elytris viridi-metallicis, nitidissimis. 
Hab. Queensland. 

Ovate, everywhere black except the elytra, slightly shining on the 
prothorax and beneath, the upper surface irregularly covered with deep 
round punctures, most numerous on the sides of the prothorax pos- 
teriorly and base of the elytra, but which gradually disappear towards 
the apex, the punctures small on the head, prothorax, and scutellum, 
but nearly all with a stiff setose hair arising from the interior of each; 
elytra very convex, dark metallic green with purple and violet reflec- 
tions; legs bluigh black, finely punctured. Length 9 lines. 


Probably most akin to C. copterus, Westw., but is narrower, with 
the prothorax more convex, &c. In C. zopterus, too, the prothorax 
is a dark metallic green, and the elytra a very deep purple with 
violet reflections, particularly at the sides. The figure of Professor 
Westwood in the ‘Arcana,’ at pl. 12. f. 1 (mot referred to in the 
text), somewhat resembles the present, but is certainly not applicable 
to either of the three species there enumerated.

Osdara levicollis. 
O. capite prothoraceque nigris, levibus; elytris subferrugineis, nigro 
tuberculatis ; pedibus rufo-ferrugineis. 
Hab. Ceylon. 

Ovate, convex ; head and prothorax smooth, glossy black, very finely 
punctured ; scutellum small, triangular ; elytra pale ferruginous witha 
tinge of grey, covered with irregular lines of black tubercles which, 
under the lens, are seen to be composed of smaller ones (from 2-10) ; 
amongst these, in the intervals, a few deeply impressed punctures ; legs 
bright reddish-ferruginous, anterior and intermediate tibize with a small 
rounded tooth near the extremity internally ; antennze at the base and 
palpi ferruginous; body beneath dark brown, coarsely punctured. Length 
4 lines. 


This very interesting and distinct species agrees generically, ex- 
cept as regards the mouth, which has not been examined, with O. 
picipes, save in the toothed tibie, which in this instance can only be 
considered of secondary importance. Both species have more or 
less of a gloss, which has the appearance of being due to varnish ; 
the black shining prothorax of the present, however, contrasted 
with the elytra,is very marked, and recalls many Adesmie, to which 
also it is very similar in form. A single specimen sent by Mr. 
Thwaites from Ceylon is in my collection. 


Ozoryrus [Helopide }. 


Characters nearly as in Osdara, Walker*, but differs in the epi- 
stome not being separated from the front by any groove, by the 
absence of the scutellum, by the form of the tibiee, which are fusi- 
form and attenuated most at the extremity, and by the shortness of 
the tarsi, the claw-joint being as long as the rest together. As 
secondary characters, the form is narrower and more convex, the 
antennee shorter, and the prothorax gibbous anteriorly. As in 
Osdara, the prosternum has a sharp-keeled process which is received 
into a corresponding notch of the mesosternum, and the intercoxal 
plate is broad and rounded anteriorly. The same varnished appear- 
ance is also as noticeable, but only on the elytra. In Ozotypus the 
tubercles which cover the upper surface are smaller, more regularly 
arranged, and each tipped with a short curved hair, which is not the 
case in Osdara. In both genera the tarsi are all nearly of equal

O. ferrugineus, tuberculatus, tuberculis setigeris. 
Hab. Ceylon. 

Subovate, ferruginous, almost everywhere covered with setigerous 
tubercles, except the epistome and antennz ; head rather small, slightly 
concave in front; prothorax transverse, rounded at the sides, produced 
into an angle anteriorly, a prominent gibbosity in front partially over- 
hanging the head, and irregularly studded with granular tubercles; 
elytra nearly ovate, wider than the prothorax at the base, the tubercles 
closely and regularly arranged in lines (nine or ten on each); legs 
reddish-ferruginous, rather short, slender, closely covered with small 
tubercles bearing rather longish sete; tarsi very short, the basal joint 
shortly triangular, the rest, except the last, very transverse and clothed 
with sparse stiff hairs; antennze rather more than a fourth as long as 
the body, more claviform than in Osdara picipes; eyes brown; man- 
dibles dusky ; body beneath dull ferruginous, Length 4 lines.

Narrowly oblong, with a short pale-greyish pile varied with black ; 
head and prothorax black, with two greyish or dull-white stripes from 
between the antenne and eyes, and terminating at the posterior border 
of the latter; antennz three to four times as long as the body, black, 
the last three joints white; eyes dark horn-colour; prothorax longer 
than broad, narrowed in front; scutellum small, transversely oblong; 
elytra subovate, dull greyish, with large black approximate or confluent 
patches; legs black, the first joint of all the tarsi ashy above at the 
base ; body beneath dark brown, slightly shining, margin of the me- 
tasternum and of all the abdominal segments greyish. Length 7-8 lines. 


This is the largest and most robust of all the described species, 
and nearest in colour to A. parvula, Thoms. The spots on the

M. variegatus, Ol., is distinguished from this by its pale-ashy 
pubescence, narrower form, antennz scarcely twice the length of 
the body, and larger spots. It is not impossible, however, that this 
may turn out to be only a strongly marked local sub-species. 


Mecocerus maculosus. 


M. subelongatus, griseo-ochraceus, atro maculatus; prothorace longiore 
quam latiore, postice attenuato ; antennis pedibusque atris. 
Hab. Ceram. 

Rather elongate, pale greyish, slightly tinted with ochraceous, and 
spotted with black; head with two hairy, greyish stripes between the 
eyes, the sides below obscurely punctured; prothorax much longer 
than broad, narrowed behind, black, a central stripe and two spots on 
each side greyish; scutellum black; elytra subparallel, slightly de- 
pressed, ochraceous with large black spots, seriate-punctate ; legs black, 
in ¢, moderately elongate, slender, the first anterior tarsal joimt not 
longer than the succeeding ones together (in 2 the two intermediate 
tarsal joints longer than the claw-joint) ; body beneath black, the sides 
of the metasternum and abdomen with a double row of dull ochraceous 
spots; antenne black, robust, nearly three times as long as the body 
(in 9 extending beyond the base of the prothorax). Length 8 lines. 


On a superficial examination this might be taken for a small 
variety of the above ; but in addition to the distinctions noted in the 
description, it may also be observed that the spots in this species are 
much larger and form a less numerous series along the suture. Mere 
colour, in the Anthribide, is not to be depended on unless ac- 
companied by a certain variation of pattern, as is the case in this 
instance. 


Mecoerus allectus.

Hab, Cambodia. 
Rather short, with a greyish-yellow pile; head black, an elongate-

obcordate yellowish spot on the vertex, descending between the eyes 
but not passing beyond them; antennz nearly three times as long as 
the body in 6, black, the intermediate joints greyish at the apex; 
prothorax as long as broad, an irregular patch on the disk, apparently 
made up of smaller spots, and occupying its whole length, occasionally 
two or three smaller spots at the side; scutellum small, triangular, 
black; elytra short, broadly ovate, greyish yellow, with four principal 
spots on the disk, the shoulder, a few smaller spots at the sides (some- 
times nearly obsolete), and several at the apex black; legs of moderate 
length, the anterior but little produced in ¢, femora and tibize obscurely 
ringed with grey, the basal and claw-joints of the tarsi ashy, except at 
the apex; side of the propectus, metasternum, and abdomen closely 
covered with a yellow pile, a spot on each side of the segments and 
the middle of the apical one black. Length 9 lines. 


In none of the species described above have the males a spined 
propectus. 


Deornena { Anthribidee]. 


Head small, not contracted below the eyes, rostrum very short. An- 
tennze 12-jointed, very slender, much longer than the body, arising 
from a cavity beneath and a little in front of the eye, the first joint 
swollen at the base, gradually diminishing upwards, and terminated in 
a truncated apex, the second as long as the first, but slenderer and 
obconic, the remainder to the eighth inclusive subequal, filiform, their 
apices more or less tumid, the apical third of the ninth and three ter- 
minal joints forming an oblong slender club. Eyes large, lateral, deeply 
emarginate beneath. Antennary cavity grooved above. Epistome and 
lip forming together a small triangle covering the centre of the man- 
dibles. Palpi filiform. Prothorax convex, rounded anteriorly, as wide 
as the elytra at the base, the carina immediately in contact with the 
base at the middle, but slightly and gradually diverging towards the 
side, forming a sharp angle at its flexure, then continued to half the 
length of the prothorax, where it suddenly ceases. Elytra convex, not 
gibbous at the base. Legs of moderate length, first tarsal joint elongate. 


The insect which has served for the above generic description is 
exceedingly like Protedus mcrens, Pasc.* On examination, how- 
ever, they will be found to be not even generically identical, the 
twelve-jointed antenne and its club, composed not of three only but 
also by part of a fourth joint, being, I believe, unparalleled among the 
Anthribide, and the emarginate eye and the position of the abbre- 
viated carina being quite different in Protedus. I do not here more 
than allude to the enormous size of the two intermediate tarsal joints, 
as it is just possible that that may be only a sexual character. The 


* Ann. and Mag. Nat. Hist. 3rd series, v. p. 39. 


332 Mr. F. P. Pascoe on some new or little-known 


emargination of the eye corresponds to a kind of groove in the upper 
portion of the antennary cavity, and is obviously intended to allow 
the antenne to be thrown well back; this structure does not exist 
in Protedus. Another peculiarity is the form of the basal antennary 
joint, which has a pyriform shape, but with the small end at the 
apex, which is the reverse of what generally occurs ; but some slight 
approach to this is made in Protedus, where the greatest diameter 
is in the middle. 


Deothena platypoda. (Pl. XVI. fig. 1.) 


D. elongato-ovata, nigro-pubescens, albo varia ; tarsorum articulis duobus 
intermediis peramplis, 
Hab. New Guinea (Mysol). 

Elongate-ovate, somewhat sparsely covered with dull black, varied 
with white, coarsish, slightly curved hairs; head with the pubescence 
nearly entirely white ; prothorax with two large black patches on the 
disk, divided by a very narrow median line, and two smaller ones on 
each side ; scutellum rounded below, very indistinct; elytra obsoletely 
punctate-striate, the sides and middle black, the basal and apical por- 
tions white with a few oblong black spots; pygidium white; antennze 
dark brown, paler at the base; eyes and mandibles black; maxille, 
palpi, and labrum rufous; body beneath and legs white. Length 
22 lines. 

Owing to the somewhat sparse pubescence, the darker ground is 
seen beneath the white hairs. thus giving them a pale-ashy hue. 
The appearance of the markings seems to show that the proportion 
of the two colours may vary. 


Pre@nta [ Anthribide }. 


Head rather broad in front, the rostrum very short, slightly emarginate 
at the apex for the insertion of the small epistome and lip. Antenne 
short, eleven-jointed, arising from a cavity beneath the rostrum and 
close to the eye, the first two joints ovate, thickened, the remainder to 
the eighth inclusive more or less conic, the last three forming an ovate, 
compact, depressed club. Eyes large, round, nearly entire. Palpi slender, 
hairy, the last joint of the maxillary fusiform. Prothorax transverse, 
rounded in front and at the sides, the carina basal, and terminating 
close to the anterior border of the prothorax. LElytra short, convex, 
parallel to the base of the prothorax. Pygidium small, narrow. Legs 
rather short. Tarsi short, the basal joint scarcely larger than the inter- 
mediate two. Claws strongly toothed at the base. 


A short convex form, very much resembling Misthosima in appear- 
ance, but differing in the subrostral insertion of the antenne, the 
ovate compact club, short tarsi, and other characters. The short, or 


id

rather, perhaps, the entire absence of rostrum will at once prevent 
its being confounded with any genus having its attenuated club of 
the same form, such as Ethneca, Penestica, or the females of Anthribus. 


Picnia saginata, (Pl. XVI. fig. 8.) 


P. breviter ovata, pube nigra albo maculata vestita ; elytris vage seriatim 
punctatis. 
Hab. Borneo. 

Shortly ovate, covered with a close black pile with white spots; 
head nearly circular in front, but a little narrowed below the eyes, no 
raised line, a few white hairs mixed with the black; antennz not longer 
than the breadth of the head, black, the club occupying rather more 
than a third of the total length ; prothorax as broad as the elytra, black, 
passing into white at the sides, with a few white spots on the disk; 
scutellum transverse, white; elytra black, irregularly spotted with 
white, especially near the base and apex; body beneath and legs with 
a close greyish-white pile. Length 2 lines.

Zygenodes monstrosus. (Pl. XVI. fig. 5.) 


Z. fuscus, sparse griseo pubescens; elytris singulis fasciculis tribus prope 
suturam sitis. 
Hab. Natal. 

Dark brown, with a sparse greyish pile obscurely clouded with dull 
fulvous; head a little broader than the prothorax, flat and triangular 
in front, uniformly of an obscure grey; prothorax nearly twice as broad 
as long, the disk irregular, subquadrituberculate; the carina prominent; 
scutellum triangular, pale grey ; elytra not broader than the prothorax, 
irregular, punctate-striate, on the disk a few raised points, which are 
rather darker than the rest, and on a line parallel to the suture three 
dense fascicles of pale-greyish hairs, the first and largest near the base, 
the other two towards the apex; body beneath brown, with greyish 
hairs; legs dull testaceous, with darker rings; antenne pale greyish 
yellow, the third joint, upper part of the fourth, and fifth near the apex, 
and the last three forming the club, black; eyes dark brown. Length 
13 line. 

This curious Anthribid, agreeing generically with Zygenodes, 
differs remarkably in colour as well as in the irregularity of its sur- 
face from Z. Wollastoni; but that a genus so peculiar should be 
represented in countries so far apart, although by no means singular, 
is a fact well worthy of note. It is probable that hereafter the 
genus may be found to be rich in species ; there are two new ones 
in Mr. Bowring’s extensive Asiatic collections, as well as numerous 
others belonging to genera which I have proposed in this Journal

NESSIARA. 
Pascoe, ante, p. 60. 


Nessiara scelesta. 


N. fusca, pubescens ; prothorace elytrisque planatis, his singulis bituber- 
culatis, macula magna communi nigra. 
Hab. Island of Mysol (New Guinea). 

Clothed with very short, dark-tawny-brown hairs ; head finely punc- 
tured, a single short central carina on the rostrum, dark brown passing 
into black at the mouth and mandibles; antennz not longer than the 
rostrum, brown, the two basal joints yellow; prothorax flattened above, 
the depressed portion at its junction with the side forming a sharp, 
irregular, dark-brown or black line; scutellum small, transverse; elytra 
short, seriate-punctate, the disk depressed, somewhat concave, having 
an obtuse spreading tubercle at each angle, the middle of the depres- 
sion with a large subquadrate black patch ; legs dark brown, the tibie 
and tarsi ringed with grey ; body beneath brownish black, with a very 
thin greyish pubescence. Length 4 lines. 

Not quite so much depressed as N. planata (ante p. 60), with 
the median patch of Nessa centralis (Ann. and Mag. Nat. Hist. 3 ser. 
iv. p. 329), and much darker than either of them. Among the 
undescribed species in Mr. Bowring’s collections, there is one with 
the sides of the rostrum dilated in a most extraordinary manner. 


GorpHanss [ Lamiide]. 


Head quadrate in front. Eyes small, lateral, reniform. Antenne se- 
taceous, longer than the body, arising from short, moderately distant 
tubercles, the basal joint rather elongate, subcylindrical, the third long- 
est, the remainder gradually shorter. Epistome and lip very short, 
transverse. Mandibles entire at the apex. External maxillary lobe 
elongate. Prothorax subovate, unarmed. Elytra rather depressed, 
broadest at the base, the sides rounded, the apex oblique. Legs mode- 
rate, femora clavate, tarsi slender, the basal joint of the four posterior 
elongate. Pro- and mesosterna simple. 


In habit this insect resembles Glaucytes, but is a true Lamiid, 
although its exact affinity is not very obvious; for the present, how- 


ever, I am disposed to place it among the Acanthocine, perhaps 
near Liopus or Edopeza.

Pubescent, deep black, varied with a nearly pure white (the figure 
will give a better idea than any description), a few bristly hairs fring- 
ing the sides of the elytra; tarsi brownish, and the terminal joint 
yellowish white; antennz slightly ciliated beneath, black, the fourth 
joint, except at the apex, and last four joints white; body beneath 
pitchy, with a sparse silvery pile. Length 4 lines.

Agelasta Mouhotit. 


A. cinereo fulvoque pubescens, nigro maculata; elytris fasciis duabus 
fuscis ornatis ; tibiarum apice tarsisque nigris. 
Hab, Cambodia. 

Sparingly pubescent, the dark shining epiderm everywhere more or 
less visible; head and prothorax with a thin fulvous pile, spotted with 
dark brown on the latter ; the fulvous passes into ashy posteriorly, and 
is continued on to the scutellum and base of the elytra, where it is 
limited by a broad band of dark brown, having its posterior border 
very irregular; the rest of the elytra is fulvous with a denticulate band 
towards the apex; and the whole, not occupied by the two bands, is 
dotted with small brown or nearly black spots, the centres of each 
being occupied by a shallow puncture ; legs ashy, the lower half of the 
tibiz and the tarsi black; antennz scarcely longer than the body, 
black, the first three, base of the fourth, and the fifth joints ashy ; body 
beneath with a thin ashy pile. Length 5-6 lines. 


This very distinct species, which is perhaps most nearly connected 
with A, amicus, Wh., may be recognized by the clear ashy-grey at 
the base of the elytra, contrasted with the rich-dark-brown band 
which succeeds. I have dedicated it to M. Mouhot, who, as is well 
known is now, and has been for some years, investigating the Zoo- 
logy of Cambodia and Siam. 


Agelasta rupta. 


A, obscure-griseo pubescens, nigro maculata; efytris fasciis duabus den-

Hab, Cambodia. 

Sparingly pubescent, dull greyish, spotted and banded with black ; 
head yellowish grey, obscurely spotted; antennz longer than the body, 
the first two and basal half of the third joint grey, the remainder 
black, with the fourth, sixth, eight, tenth, and eleventh at their bases 
more or less ashy; prothorax very short and transverse, yellowish grey, 
spotted with black; scutellum nearly quadrate, the apex slightly 
rounded ; elytra short, subparallel, irregularly punctured, greyish, a 
toothed band between the base and middle, and a narrower waved in-

- brown, with a very thin greyish pile. Length 5 lines. 

Resembles the last in colour, only it is much less pure, and the 
elytra has not the ashy base of that species. The prothorax is un- 
usually short for an Agelasta.

. 
A, piceo-fusca, pilosa, atra, murino alboque lineata; antennis pedibusque 
annulatis, illarum articulis terminalibus brevibus, ciliatis. 
Hab, Cambodia. 

Pitchy brown verging to black, with a short close pile, running in 
narrow, longitudinal, irregular and partially interrupted lines of brown- 
ish grey and white, bearing similar lines, or here and there on the 
elytra spots, of the black epiderm between them; antennz scarcely 
longer than the body, more or less brown and black, the fourth to the 
seventh joints inclusive white at the base, the apex of the latter and 
the remainder (which are much shorter) densely ciliated beneath ; legs 
greyish white varied with brown; tarsi greyish white, the apex of the 
fourth joint and claws black; body beneath pitchy black, with a greyish- 
white pubescence. Length 73 lines. 


The specimen described above is probably, from the structure of 
the antenne, a female ; the same crowding together of the terminal 
joints is seen also, and in the same sex, in A. polynesus, White. 
Like the last, it was sent from Cambodia by M. Mouhot.

Robust, dark brown, covered with short closely set hairs; head 
slightly gibbous between the eyes, with an impressed longitudinal line, 
rusty yellow, more or less varied with dark brown; prothorax trans- 
verse, narrow anteriorly, the disk irregular, bituberculate at the side ; 
an impressed line posteriorly, rusty yellow, with three longitudinal 
bands on the disk; scutellum transverse, rounded below, black, the 
sides paler ; elytra much broader than the prothorax, gradually narrow- 
ing from the shoulders, which are very prominent and produced ante- 
riorly, a small tubercle at the base, covered with pale-yellowish hairs, 
and irregularly spotted with black, particularly at the base, where they

become more or less confluent, more crowded also towards the apex 
and at the sides, bordered, particularly on the suture, by a rose-red 
line, three longitudinal lines of the same colour on each, the middle and 
exterior extending nearly to the apex; legs rose-red, annulated with 
black, the last two tarsal joints black; body beneath rose-red, the 
centre of each abdominal segment black at the base; antenne with 
the basal joint shorter than the third, black, the two first and base of 
the remainder rose-red. Length 11 lines. 


Rather larger than NV. thoracica, Wh., to which it bears a general 
resemblance, but distinguished by the comparative regularity of the 
disk, and the absence of the peculiar medio-basal fissure of the pro- 
thorax.

N. subangustata, grisescente tomentosa, variegata ; prothoracis lateribus 
tuberculiferis; elytris busi piloso-cristatis ; tibiis anticis rectis. 
Hab. Cambodia. 

Rather narrow, the male broader, covered with a dense, very pale- 
greyish tomentum, spotted with a darker or mouse-coloured grey ; 
head rather small; eyes and lip black; antenne rather more than two- 
thirds the length of the body, dark grey with very pale spots; pro- 
thorax narrower than the elytra, subtransverse, irregularly tuberculate, 
especially towards the base, the side with a few short tubercles, parti- 
ally disposed in two rows ; scutellum transverse ; elytra broadest at the 
shoulders, gradually narrowing towards the apex, irregularly costulate 
especially towards the apex, coarsely punctured, the base on each side 
with a short, narrow, erect tuft of hair, the apex subtruncate, pale 
greyish, darker posteriorly, so as to appear as a band, the shoulder 
sometimes dark brown; legs closely covered with short hairs, pale, 
spotted with darker grey ; abdomen‘hairy at the sides, with dark-grey 
spots, the sterna reddish brown with paler spots. Length 8 lines. 


N. cylindrica, White, differs in its extraordinary fore tibie, and 
in its greatly developed lateral tubercle; and WV. Ferdinandi, Paiva, 
in the absence of the basal crest of the elytra, &e. In the latter 
species the claw-joint is scarcely half the length of the three pre- 
ceding, while in others it is as long as the rest together,—another 
instance of the shifting characters of the Longicorns, and so far of 
greater importance as the large claw-joint generally marks its pos- 
sessor to be a “‘ twig-climber,’’ in distinction to the short-clawed 
species, which are principally found on the trunks of trees.

338 Mr. F. P. Pascoe on some new or little-known 


Narrow, subcylindrical, black, covered with a short, thin, greyish 
pile; head rather short, narrowed below the eyes, the vertex length- 
ened; lip and epistome small; mandibles black, palpi ferruginous ; 
eyes (for Miphona) large, black; antennze shorter than the body; pro- 
thorax about equal in length and breadth, constricted: anteriorly, the 
lateral tubercle obtuse, with an indeterminate base; the disk deeply 
trisuleate, with three or four shorter sulci on each side; scutellum 
very transverse; elytra coarsely and remotely punctured, a little 
broader than the prothorax at the base, gradually tapering in nearly a 
straight line to the apex, which is shortly divaricate and very deeply 
emarginate, with the two apiculi formed by the emargination nearly 
equal in size and much produced, the base with two short crests, the 
inner pilose, at the apical third an oblique indistinct buffish patch ; 
legs and body beneath covered with long greyish hairs. Length 8 
lines. 


At first sight this species might be readily taken for NV. Ferdinand, 
Paiva; they are, however, abundantly distinct. Touching only a 
few characters, it may be remarked that the shorter head and larger 
eye brings this latter organ in pretty close approximation to the 
base of the mandibles; the palpi ferruginous, not pitchy black; on 
the prothorax the sulcations are deeper, and the two central elevated 
lines are entire ; the elytra are longer and narrower, the apex shortly 
divaricate, the emargination very considerably broader and deeper, 
and the inner as well as the outer apiculus equally prominent and 
pronounced (in WV. Ferdinandi, the inner apiculus is sloped away 
obliquely); there are also the two crests at the base, and the patch 
posteriorly on the elytra, no trace of either of which exists in JW. 
Ferdinandi. Numerous specimens of both species have been re- 
ceived from M. Mouhot. 


Niphona arrogans. 
NV. fusca, griseo pubescente varia; prothorace transverse sexcristato ; 
elytris rude punctatis, basi latis, apice sinuatis. 
Hab. Borneo. 

Robust, dark brown, with a short, varied, greyish pile; head greyish, 
with a few scattered punctures; antenne shorter than the body, brown 
varied with grey, particularly at the bases of the third and succeeding 
joints; prothorax transverse, narrower anteriorly, bituberculate at the 
side, the disk with a series of six short, longitudinal crests, forming a 
curved line sweeping round from the two lateral tubercles to near the 
base, greyish, darker or more fulvous posteriorly ; scutellum small, very 
transverse ; elytra rugosely subplicate longitudinally, with numerous 
coarse crowded punctures,. broad at the base, tapering gradually be- 
hind, the apex sinuate; legs short, varied with grey and brown, the 
intermediate and posterior tibie black at the apex externally, claw-

joint as long as the rest together; body beneath with a pale-greyish 
pile. Length 10 lines. 


The crescent-shaped series of short crests on the prothorax will 
readily distinguish this species; the hairs on the elytra appear to 
be very deciduous, and are generally rubbed off the more prominent 
portions. 


Sympuyzetes [ Lamiide]. 
Newman, Entomol. p. 362. 


Symphyletes pubiventris. 


S. subcylindricus, pube cinerascente fulvaque varius; elytrorum lateribus 
maculis duabus albis; maris abdominis segmento secundo ampliato, 
densissime hirsuto. 

Hab. Australia (Kangaroo Island). 

Subcylindrical, black, covered with a short, very pale ashy pile, varied 
with light fulvous, and spotted with coarse black punctures; head 
rather narrow, the vertex very convex ; antenne nearly equal in both 
sexes, not so long as the body, dark brown, not spotted, and very 
slightly ciliated beneath ; prothorax nearly equal in length and breadth, 
the anterior margin scarcely narrower than the posterior, the side a little 
rounded, although irregularly, the disk with the two usual shallow 
transverse depressions; scutellum subtriangular, rounded posteriorly ; 
elytra subparallel, the apex entire, several black shining granules 
arranged in irregular rows, and extending to near the apex, two white 
irregular spots on each side partially margined with dark brown ; legs 
and body beneath covered with a similar varied pile; the second abdo- 
minal segment in the male larger than in the female, and densely 
covered with short erect hairs. Length 8 lines. 


A more cylindrical species than most others of this genus, in 
general colour approaching S. fronticornis, Fab.; but the two white 
spots on the sides of the elytra will readily distinguish it. The 
peculiar structure of the second abdominal segment is very rarely 
met with among the Longicorns, and appears to be confined to the 
males. There is nothing to distinguish Symphyletes from Rhytiphora, 
Serv., except that the latter has not the lateral tooth on the protho- 
rax, which generally characterizes the former ; the last joint of the 
antenne, “apice repente curvato,” which Newman gives as a character, 
is only found in two or three species. How Penthea, Lap., is to be 
distinguished I don’t know; it is a stouter form, with shorter and 
more robust legs, than either Symphyletes or Rhytiphora. My Penthea 
conferta (Aru), from its toothed mesosternum and absence of anten- 
nary tubercles, must be excluded from the genus, Perhaps it should 
be placed near Coptops,Serv. The spine on the anterior coxe of the 


340 Mr. F. P. Pascoe on some new or little-known 


males is confined to S. pedicorms, Fab., and S. metutus, Pasc., and 
is absent in S. nodosus, Newm. (the type of Symphyletes) ; and any 
reliance on it as a generic character would only tend to separate 
species which ought to be kept together. 


Symphyletes variolosus. 
S. subangustatus, fusco-olivaceus, leviter pubescens; ; elytris apice sinuatis, 
bidentatis, fulvo maculatis. 
Hab. Australia (Melbourne, Moreton Bay, &c.). 
Rather narrow, dark olive, shining, with a very thin, scarcely notice- 

able pubescence, irregularly and coarsely punctured ; head rather small, 
a deeply impressed line between the eyes; antenne longer than the 
body, a little shorter in the female, brown, ciliated beneath ; prothorax 
nearly as broad as long, the anterior margin narrower than the posterior, 
the sides scarcely rounded, the disk slightly sulcated with three indi- 
stinct, interrupted, yellowish bands; scutellum transverse, rounded 
posteriorly ; elytra broadest at the shoulder, gradually tapering to the 
apex, which is sinuated with a short process on each side, almost free 
from pubescence, except the small yellowish tufts which dot their 
surface; legs dark olive; body beneath with the pile pale greyish, 
slightly clouded with buff. Length 6 lines. 

A rather common species in collections, and haying apparently a 
wide geographic range. Its nearest affinity is with S. albo-cinctus, 
Don. ; but, in addition to other characters, it wants the white band at 
the sides of the elytra. The females of Symphyletes appear to have 
a longitudinal impressed line in the middle of the last abdominal 


segment.

A, robusta, grisescente pilosa, maculis nigris irrorata ; scutello grisescente ; 
tarsorum articulis duobus basalibus albis. 
Hab, Cambodia. 

Pitchy-black, with a short pale-greyish (or inclining to yellow) pile 
sprinkled with numerous small black spots; head rather broad in front, 
the spots irregular and confused; prothorax subtransverse, with three 
obtuse tubercles on the disk (2.1), the posterior divided by a deeply 
impressed longitudinal line, the two lateral teeth very distinct; scu- 
tellum greyish; elytra rather short, broadest at the shoulders, slightly 
depressed behind the scutellum, clothed with a pale-greyish pile, 
slightly mottled with a darker grey, and thickly sprinkled with small 
black spots, which are formed almost entirely by the punctures; an- 
tenn scarcely longer than the body, the basal joint greyish, spotted 
with black, the rest black, except the second and bases of the succeeding 
ones to the ninth inclusive which are ashy-white ; eyes and mandibles 
dark brown ; legs greyish, spotted with black, the tarsi black, the two 
basal joints white ; body beneath covered with a coarse greyish pile, 
the sides of the abdomen spotted with black. Length 10 lines. 


The difference between this species and the last is greater than 
might be imagined from a comparison of the two descriptions, but it 
may be rendered more obvious by remarking that, while the spots are 
larger in A. pardalis,they have invariably around the puncture, which 
forms the centre of each, a circle of black pile, and that these spots 
often become confluent, haying a more or less patchy appearance ; 
but in A. vomicosa the spots are confined chiefly to the punctures, 
which then almost entirely constitute the spots; the two basal joints 
of the tarsi, nearly of a pure white, offer a remarkable contrast to the | 
deep black of the remainder. 


From Abryna, as originally proposed by Mr. Newman, I think it 
will be necessary to separate those species which approach Dorcadion 
in form and, except very partially in one or two of them, in the 
total absence of pubescence. For these I propose the term “‘ Apro- 
phata,” with the following characters :— 


APROPHATA. 


Head rounded, not dilated below the eyes in the male, the vertex and 
front very convex. Eyes deeply emarginate. Antennz scarcely longer 
than the body, not arising from tubercles, the basal joint short, slightly 
incrassated upwards, the third joint longest, the fourth nearly as long, 
the remainder shorter and subequal. Prothorax more or less quadrate. 


342 Mr. F. P. Pascoe on some new or little-known 


Elytra short, ovate. Legs short, robust. Prosternum slightly produced 
posteriorly; mesosternum with a corresponding process anteriorly. Ex- 
ternal angle of the anterior cotyloid cavities very large. 
The principal points which distinguish Abryna from <Aprophata 
are the rounded head, especially convex in front and on the vertex, 
the ovate elytra, and the large angulation of the anterior cotyloid 
cavities; but the habit is so very distinct that it would be doing 
violence to all our ordinary notions of generic identity to keep them 
together, although, it must be confessed, the technical characters are 
not very important, and perhaps rather questions of degree. I have, 
however, repeatedly compared all the species one with another, and 
I find every character, so far as they can be ascertained without 
dissection, usually considered of generic importance, and not men- 
tioned above, more or less variable. The species of Aprophata are 
excessively rare in collections, very little known, are natives of the 
Philippine Islands, and have all been described by Mr. Newman in 
a work which is now very scarce (the ‘ Entomologist’). The follow- 
ing dignoses of the three species may therefore be useful :— 
Aprophata eximia. A. viridi-metallica, nitidissima ; prothorace elytrisque 
maculis piligeris griseis ornatis. 
Aprophata fausta. A. nigro-chalybeata, nitidissima; elytris cyaneo-me- 
tallicis, immaculatis. 
Aprophata notha. A. nigra, subnitida; sternorum lateribus abdominisque 
segmento basali margine hirsutis, ferrugineo-fulvis. 


The last species has sometimes a slightly purplish tint, and has 
been recently received from Manilla (vid Germany), ticketed “‘ Doliops, 
n.s.” In this species, too, the two prothoracic tubercles are wanting. 


Meron [ Lamiide]. 


Head subquadrate in front. Antenne setaceous, longer than the body, 
arising from two diverging tubercles, the basal joint rather short, gra- 
dually thicker towards the apex, the third and fourth equal and longest, 
the rest more or less equal. Eyes small, deeply emarginate. Lip nar- 
rower than the epistome. Palpi small, slender, the terminal joint 
elongate-ovate. Prothorax nearly equal in length and breadth; a 
short, strong tooth at the side, with small tubercles above. Elytra 
wider than the prothorax, the sides subparallel, the base more or less 
crested. Legs robust; tibiee clavate; tarsi straight, the distal end 
thickened and covered with short hairs ; tarsi narrow, the joints trans- 
verse, except the basal of the intermediate and posterior, which are 
triangular; claw-joint moderate; pro- and mesosterna simple. 


I described two species of this genus (but without characterizing 
the genus itself) in the ‘Trans. Ent. Soc.,’ 2nd ser. v. p. 42 (July 


Genera and Species of Coleoptera. 343 


1859). It seems to be most allied to Monohammus and Dystheeta ; 
from the former it is distinguished by the terminal antennary joint 
not being longer than the one preceding (in ¢ ), as well as by differ- 
ence of habit, while Dystheta, Pasc., differs from both in the form of 

the basal joint of the antenne. 


MonoHAmMts. 
Serville, Ann, de Soc. Ent. de Fr. iv. p. 91. 


Sect. 1. Pedes anteriores maris elongate. 


Monohammus Hector. 


M. fuscus, griseo-pubescens, fulvo varius; prothorace lateribus tumido, 
tuberculo minuto instructo ; elytris fulvo irroratis, singulis macula nigra 
pone medio. 

Hab, Ceram. 

Dark brown, covered with a fine greyish pile, varied with fulvous ; 
head narrow, elongate, with a deeply impressed longitudinal line ex- 
tending from the epistome to the prothorax ; eyes large; antennze more 
than three times as long as the body, arising from two approximate 
nearly erect tubercles ; lip and epistome short; prothorax about equal 
in length and breadth, narrowed anteriorly, swelling out considerably 
at the side, and armed with a small but very distinct tubercle, the disk 
with a slightly impressed longitudinal line ; scutellum rounded poste- 
riorly, hairy, the centre glabrous; elytra rather elongate, subtrigonate, 
rounded at the apex, granulated at the base, indistinctly punctured, 
sprinkled with fulvous, behind the middle a small black spot on each ; 
body beneath dull brown; legs elongate, especially the anterior pair, 
which have also their tibize serrated internally, and armed near the 
extremity with a short spine, the two basal joints of the tarsi of the 
same pair dilated at the sides, Length 17 lines. 


The above description is drawn up from a remarkably fine male, 
with the antenne alone four and a quarter inches long. The female 
has a smaller prothorax, nearly parallel elytra, shorter legs, and an- 
tennee not more than half as long again as the body. It is allied to 
M. Alcanor, Newm., bipunctatus, Schon., and fulvo-wroratus, Blount, 
all of which are referable to M. J. Thomson’s Rhamses, a genus 
which I have not adopted, inasmuch as the single character which 
separates it from Monohammus—the spined protibie of the male—is 
so graduated that in some species, plorator, Antenor, &c. for example, 
it is difficult to decide if the little callus, which represents the spine, 
is sufficient to constitute it a Rhamses. The habit, too, is just as 
variable as in Monohammuws. 


344 Mr. F. P. Pascoe on some new or little-known 


Crreorstvs [ Lamiide]. 


Head narrow, quadrate in front. Antenne longer than the body, setaceous, 
arising from two approximate tubercles, the basal joint elongate, nearly 
cylindrical, the third longest, the remainder gradually decreasing to the 
tenth, the eleventh as long, or a little longer. Eyes deeply emarginate. 
palpi slender, the last joint elongate, ovate. Prothorax small, trans- 
verse, narrow in front, gradually expanding into a strong spine, at the 
side, near the base; the spines more or less connected by a transverse 
ridge, contracted at the base. Elytra trigonate, convex. Legs short ; 
tarsi narrow, the basal joint scarcely longer than the second, claw-joint 
elongate. Prosternum simple, slightly compressed ; mesosternum pro- 
duced anteriorly. 


Cereopsius was a MS. name in use at the British Museum, and 
adopted by me a few years ago, but has not been published to the 
present time. The genus is allied to Monohammus, differing from it, 
however, in many characters, as the approximate antenne, elongate 
and nearly cylindrical basal joint, the terminal joint also scarcely 
longer than the preceding one, in the form of the prothorax the 
whole side swelling out to form the spine, which is placed behind 
the middle, the trigonate elytra broadest at the base and rapidly 
receding towards the apex, and, lastly, the shorter legs. 

To Cereopsius must be referred the following Monohammi of Newm. : 
M. Elpenor, M. Questor, and M. Lictor. The first of these is a nearly 
unicolorous form of MM. Pretorius, Erich. One of the handsomest of 
the species has been figured by Mr. White, in the ‘Proc. Zool. Soc.’ for 
1858 (pl. 53. f. 7), under the name of Cereopsius Helena. C. exoletus, 
C. marmoreus, C. patronus, and C. histrio have been described by me 
in the ‘ Trans. Ent. Soc.’ (2nd ser. iv. and y.). It will be necessary, 
however, to form a new genus for the latter. 


Imantocera [ Lamiide]. 
J. Thomson, Arch. Entom. i. p. 188. 


Imantocera arenosa. 


I, fusca, fulvescente adspersa ; prothorace subtransverso ; antennarum arti- 
culis septem ultimis unicoloribus. 
Hab, Cambodia. 

Pubescent, dark brown, sprinkled above with pale-fulyous more or 
less confluent spots; head with a deeply impressed line between the 
eyes; antennz about one-third longer than the body in dg, shorter in 
Q, the basal joint naked, robust, roughly punctured, the rest with a 
pale-fulvous pubescence, the third and fourth joints in both sexes 
dilated at the apex, with a thick tuft of hairs, confined to the upper 


Genera and Species of Coleoptera. 345 


(7. e. when the antenne are projected forward) and apical half of the 
latter; prothorax scarcely as long as broad, with three or four short 
irregular transverse grooves, and strongly spined at the side; scutellum 
triangular, rounded at the sides; elytra not broader than the prothorax 
(including the spines), slightly round at the side, a large fulvescent 
patch at the apex, the crest at the base with a row of closely set black 
granules; legs with a pale pubescence, femora dark brown, tibize 
reddish brown; tarsi covered with a short pale-yellowish pile; body 
beneath dark pitchy-brown, almost naked, with fulvous spots on the 
metasternum, and a double row on the abdominal segments. Length 
7 lines. 


The three species of Jmantocera known to me haye a strong 
general resemblance, but, I think, may be easily distinguished by the 
following characters, which I have tabled together :— 


Prothorax short, rather broader than long ; basal joint of antenne naked, 
or nearly so, rugosely punctate. 
Last seven joints of antenne annulated with black and grey. 
I. penicillata, Hope. 
Last seven joints of antenne entirely pale fulvous. 
I. arenosa, Pase. 
Prothorax very decidedly longer than broad; basal joint of antennz 
pubescent. I. plumosa, Ol. 


M. J. Thomson’s ‘ Jmantocera plumosa, Hope? ( penicillata, 
White ?),” may be, from the “ elytra paulum abbreviata,”’ I. penicil- 
lata, Hope, only that the body beneath is not pilose. 


A genus of the Baron Dejean’s allied to Gnoma, Fab., but I believe 
not yet described, is Psectrocera, the type of which, under the name 
of Gnoma? plumigera, has been figured by Professor Westwood in 
his ‘ Oriental Entomology’ (pl. 5. fig. 3). It has the following 
characters :— 


Psecrrocera [ Lamiidee}. 


Head not broader than the prothorax, elongate behind the eyes. Antennze 
longer than the body, the basal joint pyriform, the third, fourth, and 
fifth elongate, each bearing a tuft of hairs at the apex. Eyes widely 
emarginate. Prothorax narrowly elongate, the sides subparallel, un- 
armed. Elytra short, depressed, slightly crested at the base, the crest 
granuliferous, the apex rounded, entire. Anterior legs longer than the 
others; tibie of the intermediate pair toothed externally; pro- and 
mesosterna simple. 


There is a second species in Mr. Bowring’s collection. 


346 Mr. F. P. Pascoe on some new or little-known 


Patimna [Lamiide ]. 

Head moderately broad, quadrate in front. Eyes widely emarginate. 
Antenne in ¢ twice as long as the body, distant at the base, arising 
from two short tubercles, eleven-jointed, the basal joint short, sub- 
conical, the third twice as long, straight, the fourth shorter, and with 
the remainder, except the eleventh, subequal. Palpi slender. Pro- 
thorax irregular, subquadrate, not broader than the head. Elytra more 
or less subtrigonate, convex, irregular, much broader than the prothorax. 
Legs robust, the anterior pair in ¢ elongate, and protibize curved ; tarsi 
short, the two intermediate joints dilated, the claw-joint large; pro- 
and mesosterna simple, the latter dilated posteriorly. 


The type of this genus is Golsinda tessellata, Pasc. (Trans. Ent. 
Soc. 1857, p. 49). At that time Golsinda was a MS. name of M. 
Blanchard’s, but recently M. J. Thomson (‘ Essai Ceramb.’ p. 341) 
has published it with Golsinda corallina (White) as the type. But 
the latter is not congeneric with the species described by me, and 
hence it becomes necessary to give the former a new generic name. 
The differences between the two genera are, that in G'olsinda, Thoms., 
the basal joint of the antenne is elongate—as long as the third, in 
fact—and club-shaped, while in this it is short—not more than half 
the length of the third—and subconical; the mesosternum in the 
former is produced anteriorly and bilobed behind, in the latter it is 
dilated behind, and not produced anteriorly ; there are also secondary 
characters in connexion with the antennee, prothorax, habit, and 
coloration. Olivier has given a figure of a female of a species of this 
genus (Cerambyx annulatus, 67, t. 20. f. 151), and described the 
male, which M. Chevrolat is disposed to think may be identical with 
P. tessellata. I have, however, long been of opinion that Olivier’s 
insect represented another species more nearly allied to, or perhaps 
identical with, one in the British Museum labelled “ Golsenda reticu- 
lata,” White: this agrees in some respects better with the figure ; and 
both are from India, while the species described by me has only been 
received from Borneo. Another species is described in the Entomo- 
logical Society’s ‘ Transactions,’ v. p. 41 (P. wfausta).

from the inner angle of the eye to the epistome, cheeks, front, and 
vertex white; prothorax nearly quadrate, scarcely wider than the 
head, white, with two black stripes on each side; scutellum transverse, 
rounded behind ; elytra rather short, a large trilobed patch common to 
both at the base, an irregular band at the middle, and two others at the 
apex, which are more or less connected, white ; legs black, the tibie 
obscurely ringed with white in the middle, tarsi with the two basal joints 
white ; antenne hairy beneath to the fourth joint, the fifth very slightly 
so, black, the second and third joints at the base and nearly the whole 
of the fourth white; sterna white; abdomen black beneath. Length 
6 lines. 


This, so far as the proportions between the two colours are con- 
cerned, is a very variable species ; it is allied to C. anthriboides (see 
ante, p. 130).

Hab, Cambodia. 

Light brown, covered with a short, close, pale-greyish pile, varied 
with black; head nearly quadrate in front, pale grey with three 
glabrous vertical lines, the central one becoming impressed between 
the eyes, two black spots above the epistome; eyes black, reniform ; 
antenne longer than the body, black, all the joints except the two 
basal pale ashy at the base; mandibles black; palpi reddish at the 
tips; prothorax scarcely transverse, a little narrowed anteriorly, the 
sides smoky-black, continuous with a black patch behind the eye ; 
scutellum transversely triangular, black, the centre and apex pale 
grey; elytra moderately wide, subbicostate, indistinctly punctured, pale 
greyish, towards the base a few black spots, behind the middle a sub- 
reticulate black band, and near the apex an irregular transverse line, 
also black, more or less connected with small spots behind it, faint 
spots or mark of a pale leaden grey are also more or less mixed with 
the black; legs rather robust, femora greyish, with a black band near 
the apex, tibiz black, the proximal end and middle grey, tarsi black, 
with the two basal joints more or less white; body beneath grey, the 
sides with a few black spots, middle of the abdominal segments glabrous, 
shining black. Length 7 lines. 


Broader and generally more robust than E. anthriboides, the colours 
clearer and more defined, the elytra varied with black, and all the 


joints of the antenne, except the two basal, ringed with ashy at the 
base. 


348 Mr. F. P. Pascoe on some new or little-known 


Praonetua [ Lamiide]. 
Blanchard, Voy. au Pole Sud, iv. p. 292 (Prioneta). 


Praonetha subfasciata. 


P. breviter subcylindrica, fusca, sparse fulvo pubescens; prothorace sub- 
transverso; elytris medio fascia lata grisea (fere obsoleta) instructis. 
Hab. Cambodia. 

Shortly subeylindrical, brown, thinly covered with short fulvous 
hairs; head convex in front, scarcely as broad as the prothorax; pro- 
thorax subtransverse, the anterior and posterior margins nearly equal, 
the sides rounded, sparingly punctured; scutellum rather broad, 
rounded behind ; elytra short, subparallel, irregularly punctured, with 
a few black shining granules, principally at the base and along the 
suture, a broad but obscurely defined greyish band occupying the middle 
third; legs robust; antennz longer than the body, pubescent, the 
basal joint opaque brown, nearly glabrous; body beneath reddish 
brown, slightly pubescent, second abdominal segment densely covered 
with short hairs at the sides. Length 5 lines. 


In many species of this genus the pile is so thin that the derm is 
seen beneath, thus producing an obscureness and intermixture of 
colours very difficult to define ; the broad although somewhat in- 
distinct band, however, occupying just the middle third of the 
elytra, in conjunction with its subtransverse prothorax and more 
cylindrical form, will readily distinguish this species. As in 
Symphyletes pubiventris (ante, p. 339), one of the sexes—probably 
the male—has the second abdominal segment densely covered 
with short hairs. Praonetha, Blanch., is only distinguished from 
Pterolophia, Newm., by the absence of the crest at the base of the 
elytra—a very slight character, which, as is expressly stated by 
Newman, “is sometimes scarcely apparent.’ Pterolophia, however, 
appears to me to embrace two forms :—the typical one, including 
bigibbera, varia, dispersa*, &c., which are robust, middle-sized in- 
sects (5-9 lines), somewhat cylindrical or even compressed ; and less 
robust and smaller species (2—23 lines) and as decidedly depressed. 
For the latter I have already proposed the genus Ropica. Of course 
there is nothing satisfactory in such characters when used for the 
purpose of generic distinction ; but in this and in many other cases 
it is doubtful if any more important ones can be found, capable of 
embracing a large, or even moderate, number of species. With 
regard to those names I do not propose any change here: Pterolo- 


* The two latter were described by me in the ‘ Ent. Trans.,’ under the danger 
name of Nofolophia. I believe there is no such genus: it seems to have been a 
slip of the pen for Pterolophia. Prioneta is probably a typographical error. 


Genera and Species of Coleoptera. 349 


phia, although the oldest (1842), is almost unknown to continental 
entomologists, while Praonetha (1853) seems to be generally adopted, 
nor am I sure that Pterolophia has not been already used. It is 
always more difficult to suppress an old genus than to establish a 
new one. 


Praonetha undulata. 


P, olivaceo-brunnea ; capite prothoraceque griseo pubescentibus ; elytris 
subunicostatis, apice truncatis, plaga magna ante medium fasciaque 
dentata apicem versus albescentibus. 

Hab. Moluccas (Batchian). 

Pale olive-brown; the head and prothorax sparingly punctured, and 
covered with a short thin greyish pubescence, the latter about equal 
in length and breadth; scutellum transversely subcordate; elytra 
slightly compressed posteriorly, a broad but slightly elevated carina 
near the shoulder, with a very thin greyish pile principally at the base 
and sides, a large oblique patch before the middle and a very irregular 
zigzag band behind it white; mandibles glossy black; eyes brown; 
antennze scarcely so long as the body. Length 8 lines. 


Near P. albosignata, Bl., and, after that, the largest of the genus. 


Praonetha costalis. 


P. rufo-brunnea, pube grisescente varia ; elytris tricostatis, costa interiore 
basi elevata, apice truncatis. 
Hab. Batchian. 

Pale reddish brown, varied with a greyish pubescence; head and 
prothorax yellowish grey, with small punctures and patches of brown, 
the latter nearly quadrate, with the sides slightly rounded ; scutellum 
transverse, rounded behind ; elytra subtrigonate, irregularly and rather 
sparingly punctured, tricostate, the innermost costa elevated or forming 
a slight crest at the base, the intermediate one less prominent than the 
inner or outer, the apex truncate, greyish, a broad but indistinct rufous 
brown band in the middle; antennz longer than the body, rufous 
brown; eyes brown; legs obscurely varied with greyish; body be- 
neath dull rufous brown. Length 5 lines. 


The abdomen, in my example, is exceedingly small and contracted. 


Praonetha penicillata. 
P. pallide brunnea, obscure griseo varia; elytris basi subcristatis, postice 
fasciculatis, apice rotundatis. 
Hab, Cambodia. 

Pale brown, obscurely varied or clouded with grey; head and pro- 
thorax of a nearly uniform grey, finely punctured, the latter subqua- 
drate; scutellum slightly transverse, rounded behind; elytra subtri- 
gonate, seriate-punctate, slightly crested at the base, the apex rounded,

obscurely clouded with greyish, the suture pitchy-brown, a short hori- 
zontal tuft of palish hairs posteriorly at the point where the declivity 
towards the apex commences, and below this tuft a short curved pilose 
line; antennz a little longer than the body, obscurely ringed with 
grey; legs and body beneath indefinitely grey. Length 5 lines. 


One of M. Mouhot’s discoveries, easily distinguishable by the 
little horizontal tuft on each of its elytra; in some specimens the 
suture is unicolorous, or there is a dark-coloured patch at the side of 
the elytra.

P, fusca, pubescens; prothorace subelongato, antice angustiore ; elytris 
confertim punctatis, apice - rotundatis, postice obscure griseo sub-

Hab. Java. 

Dark brown, with a scanty greyish pubescence ; head rather narrow ; 
eyes dark brown; antennz not so long as the body, obscurely ringed 
with grey; prothorax longer than broad, the anterior border much 
narrower than the posterior, brown, with two greyish stripes on the 
disk; scutellum transversely triangular; elytra slightly narrowing 
from the base, covered with large, deep, irregular punctures, a tri- 
angular greyish patch indistinct anteriorly, its posterior edge marking 
the flexure of the declivity towards the apex, and barely meeting at 
the suture, the two together forming an imperfect band ; legs and body 
beneath pale pitchy-brown, covered with a close grey pile. Length 
6 lines. 


I received this species from M. Deyrolle under the above MS. 
name, by which, I believe, it is known in the Paris collections. 


Tracuystora [ Lamiide ]. 
(Dejean), Cat. de Coléopteres. 


Head moderate, slightly dilated below the eyes. Antennz not longer 
than the body, arising from two short remote tubercles, the basal joint 
massive, gradually thickened upwards, the rest slender terete, the third 
longer. Eyes deeply emarginate, approximating on the vertex. La- 
brum and epistome very short, transverse. Palpi slender. Prothorax 
transverse, irregular, spined at the side. Elytra rugose, broader than 
the prothorax, sloping posteriorly. Winged. Legs rather slender, tarsi 
slightly dilated, the basal joint short. Prosternum simple. Meso- 
sternum with a vertical tooth. 


Dejean places this genus between his Cheromorpha and Penthea ; 
the former I do not know, nor has it been published, so far as I am 
aware: but its affinity to Penthea is by no means evident ; it seems 
to me better placed near Dorcadida and Microtraqus.

Trachystola granulata. 


T. nigra, tota pube fusco-ferruginea induta; elytris seriato-granulatis, 
seriebus duabus regione scutellari abbreviatis. 
Hab. Borneo. 


Black, opake, everywhere covered with a short, dense, brownish-fer- 
ruginous pubescence; head neither punctured nor sulcated in front ; 
prothorax transversely channeled anteriorly, five flattish tubercles on 
the disc, arranged '-’, a stout spine at the side; scutellum transversely 
subcordate ; elytra a little depressed on the basal two-thirds of their 
length, rapidly sloping beyond to the apex, on each nine rows of shining 
black granules, the inner row distant from the suture, and its granules 
oblong or almost linear, near the scutellum six granules in pairs, the 
second row of granules from the suture extending to half the length 
of the elytra, space between the suture and inner row with two irre- 
cular lines of impressed punctures, nearly all the granules with a deep 
puncture behind, Length 11 lines. 


This species differs from a Java congener in the British Museum, 
labelled Trachystola scabripennis (Dej.), in the smaller punctures 
along the sutural margin, in the second row of granules extending 
to at least half the length of the elytra, instead of only a quarter, 
and the double row near the scutellum, whilst there are only two or 
three altogether in 7’. scabripennis. A third species from Borneo, 
also closely allied, is in the same museum. 


Briuvs [ Lamiide }. 


Head nearly as broad as the prothorax, quadrate in front. Antenne 
longer than the body, setaceous, arising from short tubercles, distant at 
the base, the first joint massive, subcylindrical, the third as long as the 
first, the rest subequal. Eyes lateral, widely emarginate. Palpi 
slender, the terminal joint ovate. Prothorax subquadrate, strongly 
spined at the side. Elytra connate, tapering towards the apex in the 
male, ovate in the female, the base spined. Legs moderately long, 
anterior and intermediate coxe remote, femora subclavate, tibize spined, 
tarsi short. Prosternum simple, mesosternum truncate posteriorly. 
Proposed for the reception of Dorcadion ? spinipenne (Trans. Ent. 

Soc. 2 ser. iv. p. 252), which I described from a female specimen in 

the collection of W. W. Saunders, Esq. There are now five examples 

in the British Museum, and from one of them, a male, I have drawn 
up the above characters. Brimus differs from Dorcadion (to which 

I doubtfully referred it) in the presence of antennary tubercles and 

the greater length of the mesothorax, so that the anterior and middle 

coxe (as well also the posterior) are separated from each other by a

352 Mr. F. P. Pascoe on some new or little-known 


tact: the latter character separates it from Phrissoma, from which 
it is also distinguished by its non-yentricose elytra and the absence of 
all irregularities of surface, except at the base. -Aconodes, Pasc., 
to which it is nearly allied, has the basal joint of its antennae short 
and fusiform, and scarcely more than half as long as the third. Lastly, 
Brimus has a habit of its own distinct from all the rest of the Dor- 
cadionine, although the female has a certain resemblance to Mr. 
White’s genus Dorcadida.

Athemistus pubescens. 


A, tuberculatus, pubescens, rufo-fuscus, setosus; elytris pone humeros 
incurvatis. 
Hab, Australia (Port Philip). . 

Rather narrower than A. rugosula, covered above with a dense red- 
dish-brown pubescence, and with longer slender erect hairs interspersed , 
head very convex in front ; prothorax nearly round, coarsely punctured, 
a small tooth at the side, and a tubercle above it; scutellum very small, 
triangular ; elytra covered with numerous irregular granulations, nar- 
rowly ovate, very slightly prominent at the shoulder, and rather con- 
cave behind it, the apex entire; legs moderately robust ; body beneath 
reddish brown, slightly pubescent. Length 5 lines. 


Resembles A. rugosulus, Guér. (Parmena), but is at once distin- 
guished by its pubescence. In Major Parry’s collection. 


Ecututstatvs | Lamiidee }. 


Head convex in front; eyes oblong, scarcely emarginate. Antenne 
setaceous, longer than the body, arising from two diverging tubercles, 
the basal joint robust and longest, the third with the remainder sub- 
equal. Epistome and labrum small, narrow. Palpi slender, the last 
joint obliquely truncate. Prothorax transverse, strongly spined at the 
side. Elytra short, ovato-conical, each with a nearly central elevated 
spine, the humeral angle extending beyond the base of the prothorax. 
Legs long, robust, femora not clavate. Tarsi with the basal joint 
nearly as long as the two next together. Prosternum toothed. 


The characters which distinguish this genus from Ceregidion con- 
sist principally in the diverging antenniferous tubercles contrasted 
with the remarkably erect and nearly contiguous ones of the latter, 
in the toothed prosternum, and the long antenne, all the joints of 
which, except the second, are nearly of equal length ; while in Cere- 


Genera and Species of Coleoptera. 353 


gidion they are scarcely longer than the body, the basal joint being 
shorter than the third and fourth, which are nearly equal, and the 
remainder rapidly diminishing. The habit, however, is so similar 
to Ceregidion, and is in itself so remarkable, that it would be natur- 
ally inferred that they were not only nearly allied—as in truth they 
are—but that they were also natives of the same regions. This 
supposition is, however, doubtful,—Major Parry, to whom this, I be- 
lieve, unique Longicorn belongs, having a note to the effect that it 
was taken from a box of Mexican insects. Notwithstanding, I can- 
not help thinking that, like Cerwgidion, it is a native of Australia. 


Echthistatus spinosus. (Pl. XVII. fig. 8.) 


E. fusco-piceus, sparse pilosus; prothorace disco subquinquespinoso. 
Hab. Australia? 

Dark pitchy brown, roughly tuberculate above the interstices, with 
small patches of short fulvous hairs; head with a V-shaped impression 
above the epistome; prothorax wider than long, the posterior margin 
narrowest, the side with a strong median spine, surrounded with tuber- 
cles at its base, the disk with short spines, three of which only are at 
all prominent, two anterior and one posterior, and behind each of the 
anterior ones two smaller tubercles ; scutellum quadrate-cordate, con- 
vex, hairy; elytra short, broader than the prothorax at its base, pro- 
minent at the shoulder, thence slightly dilating to one-third its length, 
and gradually rising above into a large somewhat curved spine, then 
narrowing rapidly to the apex, which is truncate, with the external 
angle pointed; legs slightly pubescent, the thighs pitchy, tibia ob- 
scurely ringed with white, tarsi brown; antennz twice as long as the 
body; beneath pitchy, with a few dull fulvous hairs. Length 6 lines.

Rather broad; head reddish testaceous, sparingly pubescent ; eyes 
and mandibles black ; prothorax greyish brown, the sides varied with 
rufous; scutellum transverse; elytra remotely seriate-punctate, pale 
ereyish brown, with a fine silky pubescence, a large and very distinct 
spot at the base, common to both, and, another, on each, behind the 
middle and towards the side, pure white; antennze brownish, the third . 
and fourth joints pale at the base; body beneath and legs pale rufous 
testaceous. Length 4 lines. 


This pretty Longicorn connects my Jolea histrio with the more 
2c2 


354 Mr. F. P. Pascoe on some new or little-known 


uniformly coloured species represented by Jolea prolata, longicornis, 
and others ; and at the same time it is so evidently allied to Seriaia, 
that I do not see any characters by which they can be kept apart. 
Serivia, as the oldest name, must therefore be adopted. In addition 
to the characters previously given (Trans. Ent. Soc. 2 ser. iv. p. 45), 
the genus may also be recognized by the little narrow lobe on the 
disk of the prothorax posteriorly, but which never attains to its 
margin. 


Serivia cephalotes. 


S. rufo-testacea; elytris, basi excepta, infuscatis, griseo pubescentibus. 
Hab. Batchian. 

Moderately narrow, pale reddish testaceous; head and prothorax ob- 
soletely punctured, finely pubescent; scutellum small, triangular ;-elytra 
remotely seriate-punctate, very dark ashy, and, from the varying light 
of the somewhat silky pubescence, much paler in certain positions, 
especially towards the apex ; antenne two or three times as long as the 
body, brownish, base of the first and fourth joints testaceous; legs and 
body beneath pale testaceous ; eyes and mandibles black. Length 33-4 
lines. 


In one of my specimens the breadth of the head is nearly twice 
that of the prothorax ; in two others it is considerably less, although 
still exceeding the ordinary size; the antenne, also, are of variable 
length. 


Seriaia sedata. 


S. rufo-testacea, sat lata; elytris grisescente pubescentibus, apice aliquando 
infuscatis ; oculis, antennis, mandibulisque nigris. 
Hab. Siam. 

Reddish testaceous, inclining to ferruginous, with a thin greyish 
pubescence ; head and prothorax with shallow scattered punctures, the 
latter transverse and narrower than the former; scutellum broadly 
triangular; elytra seriate-punctate, the apex in some individuals black, 
more or less brown or entirely concolorous in others; eyes and mandi- 
bles black; antennze greyish brown, pubescent, half as long again as 
the body, rather stout, the fourth joint with the basal half, and occa- 
sionally the bases of the sixth and eighth also, reddish ferruginous. 
Length 52 lines. 


The rings on the antenne are in some examples scarcely apparent. 


Evumatues [ Lamiidee}. 
(Dejean, Cat. de Coléop.) 
Head short, narrower below the eyes. Antenne setaceous, longer than 


the body, distant at the base, the first joint of moderate length and 
thickness, the third longest of all, the remainder gradually decreasing

in size. Eyes large, deeply emarginate. Epistome and lip short, the 
former scarcely broader than the latter; terminal joint of the palpi 
ovate, pointed. Mandibles entire at the apex. Prothorax subquad- 
rate, slightly toothed at the side. Elytra subdepressed, wider than the 
prothorax, the sides gradually rounded to the apex. Legs rather short, 
anterior cotyloid cavity slightly angulated externally, femora subcla- 
vate; tibiw straight; tarsi narrow, the basal joint of the posterior as 
long as the rest together, the claw-joint short, claws strongly toothed. 

Prosternum simple, mesosternum keeled. 

The toothed claws, combined with the keeled mesosternum, will 
distinguish this genus from Hebestola, which appears to me to be its 
nearest ally. Humathes undatus, published by me in the Entomolo- 
gical Society’s ‘ Transactions,’ 2 ser. iv. p. 251, I believe to be con- 
generic with ZL. jaspidea (De}.).

Sternacanthus Bates. 
S. ater, nitidus; elytris fasciis subintegris tribus rubris. 
Hab. Para. 

This insect has long stood in my cabinet as S. undatus, Ol. Mr. 
Bates, however, has recently called my attention to the differences be- 
tween the two; and since that I have seen two specimens of the true 
undatus in the extensive collection of Wm. Jeakes, Esq., and which 
were formerly in the possession of the Marquis de la Ferté. In the 
true undatus the bands have precisely the undulating character re- 
presented in Olivier’s figure, and are very different from the nearly 
straight, although slightly toothed bands of the Batesii; the habit 
is also different ; and were the two insects compared, other characters 
would doubtless be found to distinguish them.

Stenygra contracta. 
S. fusca, nitida; prothorace ampliato, longitudinaliter plicato; elytris

Hab. Amazons (Napo). 

Dark glossy brown, very sparingly furnished with long pale-yellowish 
hairs; head moderately elongate, roughly punctured ; prothorax sub- 
globose, broader than the elytra, marked longitudinally with numerous 
fine lines or plaits; scutellum triangular, with a greyish-white pile ; 
elytra elongate, narrowed in the middle, prominent at the shoulders,

and raised at the base, the apex rounded and swollen, an oblique 
narrow yellow basal line, and at about the middle another, but dilated 
outwardly, the two forming together an interrupted x mark; femora 
moderately clavate, the posterior with a spine at its extremity, tarsi 
slightly curved, densely clothed with golden-yellow hairs internally on 
its lower half, tarsi rather short; antennze with a silvery pubescence, 
the terminal joints very strongly dilated. Length 11 lines. 


Near S. coarctata, Fab., but with the prothorax shorter and more 
rounded at the sides, its surface longitudinally marked with fine, 
wavy, more or less connected lines; the elytra much longer and 
narrower, and more decidedly contracted in the middle, &c. &e. 


StHELENUS [ Cerambycide ]. 
Buquet, Ann. Soc. Ent. de France, 1859, p. 621. 


Sthelenus morosus. 


S. fuscus, opacus; elytris abbreviatis, singulis maculis elongatis tribus 
flavis; antennis articulo secundo longiore, incrassato, piloso. 
Hub. Caraccas. 

Dark brown, opake, with a few stiff black hairs; head wider than 
the prothorax, and about one-half its length, covered with large, coarse, 
often confluent punctures, somewhat transversely arranged, especially 
on the vertex, front slightly concave ; lip small, ferruginous; palpi of 
nearly equal length, pale ferruginous ; prothorax nearly cylindrical, a 
little constricted towards the base, the disk with numerous fine trans- 
verse irregular plaits; scutellum rather elongate, rounded behind, 
somewhat concave ; elytra coarsely punctured, much wider than the 
prothorax, nearly flat above, curved slightly inwards at the side, not 
extending beyond the base of the fourth abdominal segment, each 
having three oblong longitudinal patches (the last two nearly con- 
tinuous) of bright-yellow, curved, appressed hairs; legs rather short, 
tibize and tarsi slender ; body beneath pitchy brown ; antenne scarcely 
longer than the body, the third joint thicker than the basal, and largest 
of all, hairy, the seventh to the eleventh inclusive short and a little 
dilated. Length 8 lines. 


The above applies exclusively to the male ; the female is smaller, 
more ferruginous, with longer antenne, the terminal joints not 
dilated, but the third as thick in proportion as in the male. Instead 
of referring this species to the genus Sthelenus of M. Buquet, it will 
perhaps be thought that it would have been more advisable to have 
considered it as the type of a new one. I regard Sthelenus, however, 
as very closely connected with Ozodes, Lew. ; and as in that genus we 
find the prothorax more or less nodose, and the third (and sometimes 
the fourth and fifth) joints of the antenne considerably incrassated, 


Genera and Species of Coleoptera. 307 


so we may expect to find the same variations in the present. Beyond 
this, I see nothing to justify its separation from that genus. My 
example of Sthelenus ichneumoneus, Buq., is from the Amazon Valley, 
and differs in this respect, that the legs are concolorous, except the 
posterior, which are somewhat darker.

Hab. Tasmania. 

Dark brown ; head small, with shallow confluent punctures, an im- 
pressed line between the eyes; prothorax small, subequal, covered with 
coarse confluent punctures, an elliptical space, on the median line near 
the base, smooth and shining, the side with a slender, elongate, straight 
spine; scutellum small, triangular; elytra broad, a little depressed, 
five times as long as the prothorax, pale fulyous yellow, the base and 
margins dark chestnut-brown, thickly and deeply punctured, gradually 
decreasing in size and proximity as they approach the apex, each 
elytron with two smooth elevated lines, not extending to the apex, and 
terminating in two long acute spines; legs ferruginous, with yellow 
silky hairs on the tibize and tarsi; antennze ferruginous, covered with 
a close greyish pubescence, except the basal and second joints, the 
third to the seventh inclusive armed with a spine at the apex; body 
beneath pitchy, pubescent. Length 10 lines. 


Very distinct, and not to be compared with any other Phoracantha 
that I am acquainted with. The amount of chestnut-brown on the 
elytra varies.

pression on each side between the eye and epistome ; eyes dark brown, 
tips of the mandibles black; antennz setaceous, rather longer than the 
body, a little hairy beneath, the fourth joint shorter than either the 
third or fifth; prothorax elliptic-ovate, with narrow anterior and 
posterior margins; scutellum subtriangular, rounded below; elytra 
rather wider than the prothorax, gradually tapering to the apex, which 
is truncate, with the outer angle terminating in a spine; each elytron 
with three equidistant, black spots, the two first oblique (downwards 
and outwards), not connected at the suture, the third forming a con- 
tinuous band near the apex; legs rather long, slender; body beneath 
rather glossy, slightly pubescent. Length 7 lines.

Reddish-chestnut, silky, covered with numerous very fine, erect 
hairs; head subtriangular in front; eyes reddish brown, tips of the 
mandibles black ; antenne rather long, sublinear, compressed, especially 
the terminal joints, the third and fifth of equal length, the fourth much 
shorter; prothorax nearly globose, except at the base, where it is 
strongly constricted, the disk with a large black spot on each side; 
scutellum nearly triangular ; elytra rather short, somewhat depressed, 
the sides parallel, the humeral angle produced, the apex entire, rounded,

A handsome and remarkable species, and not to be assimilated to 
any other known to me. In outline only it may be compared to

Hab. Batchian. 

Head short, subtriangular in front, roughly punctured, black, with 
two white hairy stripes between the eyes and antenne ; eyes rather 
large, pale fulvous ; antennze black, subclaviform, half the length of the 
body; prothorax nearly globose, wider than the head, roughly punc- 
tured, black, a line at the side and eleven spots on the disk composed 
of white hairs; scutellum elongate, narrowly triangular, densely covered 
with white hairs; elytra scarcely as broad at the base as the prothorax, 
then gradually narrowing to the apex, which is truncate, with the outer 
angle acute, nearly flat above, and, but slightly, bent in at the sides, 
pale fulvous, darker towards the apex and along the exterior margin, 
and very sparsely pubescent ; femora short, moderately clavate, yellow- 
ish red, tibize and tarsi dark brown; body beneath black, the abdomen 
glossy, with the two basal segments and sides of the metasternum bor- 
dered with white. Length 4 lines. 


T am unable to compare this well-marked species with any other 
known tome. The flat elytra very imperfectly covering the abdo- 
men, and in some degree the habit, suggest an affinity, or rather an 
analogy, with Stenopterus, Thranius, &c.

spots on the disk; scutellum transverse, rounded behind; elytra sub-

base of each, which, barely meeting below the scutellum, form together 
a rude resemblance to the letter W, behind this there is another band 
or blotch, zigzag or very strongly toothed, not extending to the side 
or meeting at the suture, and midway between the latter and the apex 
is a black irregular patch ; antennz setaceous, unarmed, shorter than

This fine Clytus will come into the section that should also con- 

tain such species as annularis, signaticollis, &e. I have not 

adopted any of the genera of MM. Leconte, Cheyrolat, and Thomson, 
which they have proposed for comparatively a few of the members 
of the old genus Clytus. The species generally comprised under this 
name, although remarkably heterogeneous in many respects, are 
connected by characters so intermediate, that it appears to me to be 
impossible to fix any satisfactory limits to many of these groups. 
As an example, the genus Cyllene, Newm., confined by M. Thomson, 
as I think it should be, to C. nebulosus, is by M. Chevrolat (no mean 
authority) made to include a number of North American species 
also. Like Meronia, which, after having been divided into some 
thirty or forty genera by the Baron de Chaudoir, left a large sur- 
plusage which could not be placed in any of them, so I believe it

would be with Clytus. The genus must be worked out in its entirety, 
if it is to be divided satisfactorily. Among the Clyti, however, 
there seems to me to be two groups which, by their habit principally, 
deserve to be distinguished—one Rhaphwna, Thoms., including (C. 
quadricolor, Lap., C. leucoscutellatus, Hope, and C. placidus, Pasce., 
the other, unnamed, comprising C. lunatus, Newm., C. Hardwickii, 
White, and C. cruentatus, Pasc. Both these groups appear to be 
well limited and well marked ; but their technical characters, I fear, 
will not be very valuable. 


Zorpia [Cerambycidee |. 


Head subquadrate in front, constricted into a neck behind. Eyes narrow, 
elongate, deeply emarginated. Antenne eleven-jointed, filiform, as 
long as the body; all the joints, except the second, nearly equal in 
length, the basal thickened, obconic. Palpi with the last joint narrowly 
triangular, obliquely truncate. Prothorax nearly as broad as long, 
narrow anteriorly, a stout tubercle at the side. Elytra broader than 
the prothorax, subparallel, rounded at the apex. Legs slender; tarsi 
nearly linear, the basal joint elongate. Pro- and mesosterna simple. 


Near Tillomorpha and Euderces, but differing completely in the 
form of the head, the prothorax, &e. With Attodera* it agrees in 
having the prothorax of a similar character, although more robust, and 
in its neck ;* but the peculiar round, ant-like head of the latter, and 
its perfectly entire eyes, place it in a different subfamily. Of the two 
species described below, I have only seen one individual of each.

Hab. Australia (Kangaroo Island). 

Reddish fulvous, covered with a pale silky or silvery pile; head 
rather expanded below the eye, canaliculate between the antenne, 
which are unicolorous and about as long as the body; eyes slightly 
emarginate, dark brown; mandibles black at the apex; prothorax 
scarcely longer than broad, swelling out at the middle into an obtuse 
knob; scutellum small, triangular, brown; elytra wider than the pro- 
thorax, slightly incurved at the side, the apical third brownish grey or 
pale fuliginous, above which is a darker patch or band, which becomes 
gradually paler towards the suture, from the side at about the middle 
a curved line of dark thickly set hairs ascends inwards and upwards, 
terminating at a distance from the base equalling its own length, and 
bordered posteriorly by another line of pale yellow; legs dull fulvous,

Length 4 lines. 


A single specimen in Mr. Bakewell’s collection. 


Mesorira [Cerambycide ]. 


Head quadrate. Antenne setaceous, longer than the body, distant at the 
base, the first joint short, clavate, the third longest, the rest gradually 
shorter. Palpi slender, terminal joint of the maxillary ovate. Eyes 
small, lateral, reniform, widely apart in front. Prothorax ovate, 
convex, Elytra obovate, swelling out posteriorly, without humeral 
angles, not larger than the prothorax at the base, the apex divaricate, 
acute. Pro- and mesosterna simple, continuous (@. e. without opposing 
faces). Legs of moderate length; femora clavate; tarsi gradually 
dilated to the third joint, the basal as long as the two following, except 
in the anterior pair. 

The absence of humeral angles and the exact apposition of the 
prothorax to the elytra are the most striking characters of this 
genus. In these respects it resembles the Dorcadion group among 
the Lamiide; but its affinity appears to be with Z%llomorpha, 
Euderces, &c., and therefore allied to Clytus.

M. pubescens, fuliginosa, scutello elytrisque basi cinereis, his fascia trans- 
versa lunata apicem versus alba. 
Hab. Queensland. 

Pubescent, smoky brown; head nearly quadrate in front ; prothorax 
broadly ovate, its posterior margin narrowest; scutellum rather large, 
triangular, cinereous; elytra contracted at the base, gradually swelling 
out above and at the sides, attaining its greatest size at rather within 
two-thirds their length, the basal portion dull cinereous, separated from 
the rest by a sharply angled or zigzag line, a crescent-shaped white 
band on the posterior third, the apex simply acuminate ; legs rather 
robust; femora slender at the base ; the tibize slightly ciliated internally, 
the intermediate and posterior tibiz also ciliated externally at the apex ; 
body beneath pitchy, with a greyish pubescence ; antennz with the

and lip rusty brown, eye bordered with pale-yellowish hairs ; prothorax 
very slightly contracted at the base and anteriorly, its disk with four 
yellow linear spots (placed :'), and another on each side; scutellum 
triangular, dull yellow ; elytra contracted at the base, the largest portion 
at about two-thirds the length, with several fine, golden-yellow, inter- 
rupted lines, the apex spined ; legs rather robust, femora less clavate, 
but the tibie ciliated as in the last; body beneath pitchy; antennz 
and palpi ferruginous. Length 5 lines.

Hab. Queensland. 

Testaceous, varied with black, with long, scattered, very pale hairs; 
head short, slightly ferruginous, a darker patch on the vertex; eyes 
large, black; palpi ferruginous; tips of the mandibles black ; antennze 
longer than the body, the two basal joints entirely, the remainder at 
the apex, ferruginous ; prothorax shortly ovate, contracted behind, very 
minutely punctured, a short black dash on each side at the base; scu-

tellum long, subtriangular, black; elytra wider than the prothorax, the 

sides nearly parallel, coarsely and closely punctured, a semicircular 

band at the base enclosing the shoulder, a zigzag at the middle, and a 

straight narrow band towards the apex black; legs pale testaceous, 

the femora clavate, shining, ferruginous, the base pale; body beneath 

nearly glabrous, brown, darker on the throat and breast. Length 33 

lines. 

The nearest ally of this species appears to be signiferum, 
Newm., a much darker and differently marked insect. The latter, 
together with C. seutellare, Fab. ( piceum, Newm.), is referred to 
a genus neither named nor described by that author, but for which Mr. 
White has adopted, also without description, the name of Callidiopis 
(Blanch.). I don’t know what the characters may be which are to 
distinguish it from the polymorphous Callidium. The antenne and 
prothorax are as variable as the coloration.

apice extus spinosis. 

Hab. Aru. 

Robust, dark bronze-brown, more or less spotted with patches of 
ereyish hairs; head broad in front, narrowed behind the eyes, two 
slightly raised lines forming a A above the epistome, the vertex cana- 
liculate, four to six spots in a line beneath the eyes, two between and 
four behind them; prothorax very transverse, rounded and narrowed 
anteriorly in the male, the border in front nearly straight, dilated ante- 
riorly in the female, and the border broadly emarginate for the recep- 
tion of the head, dull bronze, coarsely punctured at the side, leaving a 
broad, smooth, shining line in the middle; scutellum transverse, 
rounded behind; elytra strongly sulcated, the interstices forming 
broad, raised lines, the central ones more or less united posteriorly and 
not reaching the apex, the sulcated lines filled in here and there with 
a greyish pile, forming partial spots which assume the appearance of 
interrupted bands (two or three—in some individuals scarcely ap- 
parent), apex strongly spined externally ; legs and antenne sparsely 
pubescent ; body beneath glossy chestnut-brown, a single white spot 
on each side of each abdominal segment. Length 9 lines. 


The nearest affinity of this well-marked species is with S. sulcati- 


pennis, Blanch., from which, amongst other characters, it is distin- 
guished by its metallic colour and apiculate elytra.

Tmesisternus tersus. 

T. niger, nitidus, pube subtilissima grisea tectus; elytris disperse punc- 
tatis, apice subsinuatis, muticis, fasciis duabus albis ornatis; antennis, 
tibiis tarsisque rufo-fulvis. 

Hab, Goram (Moluccas). 

Rather robust, black, shining, the upper surface covered with a 
uniform, very fine greyish pile, the two bands on the elytra alone have 
the hairs of a coarser texture; head deeply channeled in front, a 
nearly straight raised line at the root of the antenna, between them a 
few punctures only, the vertex scarcely punctured; prothorax trans- 
verse, narrowed in front, coarsely punctured on each side, leaving a 
smooth space in the middle ; scutellum nearly round ; elytra irregularly 
punctured, rather convex at the base, the apex subsinuate, unarmed, a 
pale-greyish or nearly white band at one-third the length of the elytra 
from the base, another, but curved forwards and narrower, at about the 
same distance from the apex ; antennee, tibiee, and tarsi reddish fulvous, 
sparingly pubescent ; body beneath glossy black, the sides covered with 
a glaucous pubescence. Length 8 lines. 

So very closely allied to 7’. trivittatus, Guér., as, except on com- 
paring them side by side, to be readily mistaken for it ; besides cer- 
tain differences of colour, however, 7’. tersus has the punctures on 
the elytra irregularly dispersed, not forming two or three rows near 
the suture, and the apex is entirely unarmed ; the vertex and front 
are also very slightly punctured ; the clear reddish-yellow colour of 
the antenne, tibis, and tarsi, and the leaden tint of the rest, con- 
trast strongly with the general olive hue of 7. trivitiatus. I may 
observe here that Guérin’s name is singularly inappropriate ; the 
animal has not three stripes, but two bands. Boisduval has proposed 
to remedy this by substituting “ bicinctus ;” but the law of priority, 
I fear, cannot admit the alteration. Another Z’mesisternus, from 
Ceram, although sufficiently distinct at the first glance, appears to 
me to be only a local subspecies of the present: there is the same 
general disposition of colours ; but the two bands are very indistinct, 
and the spaces between them and the apex respectively occupied by 
a series of closely arranged stripes of a pale leaden hue. I have 
seen a number of both forms, but nothing intermediate. There is 
still another form, from Makian (a small island near Batchian), 
so nearly concolorous that, except at the apex, no markings are 
visible without the aid of a lens.

Rather narrow, shining, dark brownish green varied with brown, 
with a thin, sparse, greyish pile; head grey, with an impressed line in 
the middle, and very few punctures on the vertex and front; eyes pale 
brown; antennz slender, longer than the body, the basal half pale 
green, the apices reddish yellow, the remainder darker, brownish, or 
brownish yellow; prothorax dark green, as long as broad, coarsely 
punctured, with a smooth median line; scutellum subquadrate ; elytra 
subseriate punctate, one or two faintly raised lines on each, but more 
strongly marked at the base, the apex obliquely truncate, dark green, 
behind the middle and close to the external margin a large greyish- 
white spot, surrounded, but particularly along the side, by dark brown, 
towards the apex paler, with a brownish indefinite patch; femora and 
tibie pale yellowish green, tarsi reddish testaceous; body beneath 
glossy chestnut-brown, the sides with a reddish pile. Length 5 lines.

S. fusco-niger, obscurus; prothorace antice posticeque rufo; elytris sin-

Hab, Australia. 

Dull brownish black; head subtriangular, vertex and space between 
the antennz black, stripe over the eyes and rest of the head pale red- 
dish, behind the insertion of each antenna a small tubercle; prothorax 
finely punctured, about half as long again as broad, the anterior half 
cylindrical, the posterior expanding into a mammiform tuber, and there 
nearly as wide as the elytra, the base contracted, the disk with four 
tubercles, the two posterior largest, the anterior and posterior margins 
pale red; scutellum convex, rounded, brown ; elytra narrow, parallel, 
each with four pale-yellow, raised, smooth, longitudinal lines, the two 
towards the suture united near the apex, the third about two-thirds 
the length of the first, the fourth marginal, the spaces between the 
lines punctured ; legs black; pro- and mesosterna and four anterior 
coxe red, metasternum and abdomen black, the latter with a silvery 
pubescence. Length 6 lines. 


This species will be at once distinguished from S. rectus, gram- 
micus, and deustus, not only by its greater size and more robust form, 
but by its quadrilineated elytra and dark-brown nearly black pro- 
thorax. In the fifth volume of the ‘ Transactions of the Entomo- 
logical Society,’ n. s., I proposed to separate, under the name of 
Syllitus, those species of Stenoderus with elevated longitudinal lines 
on the elytra, from the ordinary red and black ones which con- 
stituted the genus originally. The technical characters which di- 
stinguish it are perhaps only of secondary importance, as is the case

with many others in the Longicorn families, yet taken in connexion 
with the fact that one has a type of coloration different from the 
other, will, I think, justify its adoption. 


Desvs [Cerambycide ]. 


Head rounded, slightly contracted behind the eyes. Antenne setaceous, 
distant at the base, longer than the body, the first joint short tumid, 
the second very short, the remainder subequal. Eyes very large, ob- 
long, nearly entire. Lip very small, rounded anteriorly. Palpi grow- 
ing gradually thicker, the last joint subtriangular. Prothorax nearly 
equal in length and breadth, narrower in front, rounded behind, the 
sides carinated. Elytra wider than the prothorax, parallel, the humeral 
angle produced. Legs moderate, tibiee slightly curved externally, their 
margins tuberculate and fringed with short hairs, the first tarsal joint 
shorter than the two next together. Abdomen soft. 


The above description is drawn up from what appears to be a 
male, in the collection of Major Parry. It has astriking resemblance 
to a Telephorus, but is related to Vesperus, although the form of the 
head and prothorax is so far different that we miss the slenderness 
which gives such a remarkable contour to the species of that genus; 
the presence also of a well-marked carina along the side of the pro- 
thorax, which, however, does not extend its whole length, would 
alone suffice to distinguish it. It may also be noted that whilst in 
Vesperus the tibize are slender and perfectly straight, in Desus they 
are tolerably robust and curved externally, and the basal joint of 
the tarsi is shorter than the two next together, which is not the 
case in Vesperus. The form and position of the coxze, palpi, and 
antenne, except that the latter are more distant at their insertion, 
are so far identical as to call for no further notice.

Amruzs [ Cerambycidee ]. 

Head very short and rounded in front, narrowed behind the eyes. An- 
tenn eleven-jointed, arising between the eyes from short divaricate 
tubercles, two or three times as long as the body, setaceous, the basal 
joint short, narrowly subpyriform, the third twice its length, the re- 
mainder gradually longer. Eyes large, prominent, reniform. Palpi 
slender, pointed. Lip and epistome very short and transverse. Man- 
dibles entire at the apex. Prothorax elongate, irregularly subcylindrical, 
narrower than the head and elytra, unarmed. Elytra subparallel. Legs 
slender, basal joint of the tarsi elongate. Anterior cotyloid cavity 
widely angulated externally, open behind; its coxe conical, approxi- 
mate, Pro- and mesosterna simple. 

The specimen from which the above generic details have been 
drawn up was originally described by me in the ‘ Trans. Ent. So- 
ciety,’ 2nd ser. iv. p. 238, as Psilomerus ? macilentus. The generic 
name was a MS. one used for a congener at the British Museum, 
but, as I afterwards found from an inspection of the true Ps¢lomerus 
at Paris (Jardin des Plantes), had nothing whatever to do with my 
species. As I cannot refer it to any published genus, a new name 
has therefore become necessary. With regard to its affinities, I have 
with some hesitation placed it near Methia, Newm., hitherto forming 
with Dysphaga, Hald., a small group, originally proposed by Leconte, 
and principally characterized by its anterior cotyloid cavities open 
behind. M. James Thomson in his ‘ Essai,’ p. 128, combines Dectes, 
Leconte, with them; but this and Dysphaga I have not seen.

Dark brown; head narrow and elongate, a patch of yellow silky 
hairs between the eyes, dividing into angular branches below them ; 
prothorax ovate, narrower than the elytra at the base, covered with a 
silky pubescence varied with four rather indistinct yellow stripes ; 
scutellum narrowly triangular, pale yellow; elytra extending to the 
middle of the third abdominal segment, punctured at the base, a yellow 
vitreous stripe from near the base to the apex ; legs more or less hairy, 
especially on the inner side of the intermediate and posterior tibia ; 
anterior tibize with a strong tooth beneath, near the middle; inter- 
mediate and posterior femora annulated with yellow towards the base ; 
body beneath dark brown shining, the metasternum varied with indi- 
stinct patches of yellow silky hairs, abdomen elongate, very slender, the 
basal segment narrowest, the penultimate furnished with a broad bifid 
tooth at its apical margin. Length 9 lines. 


The curious bilobed tooth beneath the abdomen is not, I think, a 
sexual character, as might be supposed, as it also occurs in what 
appear to be both sexes in one or two other species of this genus. 
The abdomen is very much attenuated at the base—a character which, 
in the group to which it belongs, appears to be only of specific im- 
portance. I have not seen any other species having the protibie 
toothed.

Mr. T. V. Wollaston on the Tarphii. 371 


XXVIT.—WNotes on Tarphii; with the Deseription of an allied Genus. 
By T. Vernon Wottaston, M.A., F.L.S. 


Wurst preparing for the following Memoir on the various Tarphii 
(nine in number) which have hitherto been discovered in the Canary 
Islands, my attention was directed (in March of last year) by Mr. 
Adam White, of the British Museum, to what seemed primd facie 
to be a new species from Southern India, obtained by M. J. Wal- 
house, Esq., at Coimbatoor; and finding, after a careful dissection 
of it, that its oral organs were almost identical with those of Tar- 
phius proper, I characterized it under the title of 7. indicus, and 
appended it to my paper,—at the same time pointing out certain 
structural peculiarities, of minor signification, in which it receded 
from the typical members of the group. But on inspecting a box 
of various Coleoptera, six months afterwards, which were collected 
by Mr. Bowring at Poulo Penang (on the opposite side of the Bay of 
Bengal, in the Malay Peninsula), a much larger representative—ap- 
parently congeneric with the one from Malabar, but diverging con- 
siderably more than it did from the normal Yarphii—induced me to 
look more critically into the generic details of these two insects, and 
to compare them not only inter se, but also with those of their At- 
lantie allies. The result has been that I cannot but regard them as 
entirely distinct from T’arphius,—the main question being, whether 
they can themselves be generically associated. After fairly consider- 
ing this point, I believe that such should be the case; for, although 
they present the radical difference of one of them having powerful 
wings, a conspicuous scutellum, and setose eyes, whilst the other is 
apterous, with the scutellum but just perceptible, and the eyes naked, 
still in all their other minutiz (both external and structural) they 
have so very much in common that I am inclined to use these dis- 
crepancies for a no higher purpose than a mere sectional one,— 
though, at the same time, I have thought it better to give the second 
group a provisional name, in the event of its being considered de- 
sirable hereafter to detach it in toto from the first. 

From Tarphius proper both of these beetles (though more especially 
one of them) differ in their larger eyes and developed scutellum, in 
their less abbreviated metasternum and setose legs (the hinder pair 
of which have their cox considerably more approximated), in the 
expanded edges of their prothorax having no trace of a hollowing- 
out beneath for the reception of the antennze when thrown backward 
in a state of repose, and in the terminal joint of their palpi being 


372 Mr. T. V. Wollaston on the Tarphii. 


more elongate and fusiform. And they recede from the Tarphu still 
further in having no nodules and interrupted ridges on their elytra, 
and in their pronotum being impressed along the centre of its base 
with a deep transverse line. 

On the other hand, in their general facies and setose surface, no 
less than in the construction of their antenne and 4-jointed feet, 
and in the shape of their upper lip, and of their quadrate, corneous 
ligula and mentum, these insects are alike coincident with Tarphius, 
which is, I believe, their nearest known ally. 

After these few remarks, therefore, I think that the following 
short comparative diagnosis will be sufficient to indicate the group 
(for which I would propose the name of Tarphiodes), both abso- 
lutely and with reference to the exact points in which it differs from 
Tarphius.

In its apterous body and but very slightly developed scutellum, 
no less than in its diminished bulk, more ovate outline, and smaller, 
unsetose eyes, the present beetle approaches the normal Tarphii far 
more closely than the preceding one does; nevertheless the many 
and important characters which separate it entirely from that genus 
have already been pointed out. In external facies, however, it bears 
so strong a resemblance to those insects that I have thought it 
worth while to give a figure of it; and I have added on the same 
plate a Tarphius* proper, from each of the three countries in which

des Col. d'Europe’), and although I gave a diagnosis of it, in a foot-note, at 
p. 132 of my ‘Ins. Mad.,’ I have nevertheless thought it worthy, from the im- 
portant position which it occupies in having to be accepted as the type of the 
whole genus, of a place in the present paper. I would therefore re-characterize 
it thus :— 

Tarphius gibbulus. 
T. cylindrico-oblongus, piceus, granulis squamisque parvis fuscescentibus parce 
vestitus et pilis (nec setis) longiusculis suberectis cinereis parce tectus ; pro-

the group has hitherto been detected,—preserving also similar letters 
for their corresponding parts, in order to show at a glance that 
this analogy, which has been so much insisted upon, is not an 
imaginary one. 

Of the Sicilian 7’, gibbulus, however (fig. 2), I regret that I have 
been unable to supply the oral organs ; for the example communi- 
cated by Professor Westwood is unique in his collection, and I con- 
sequently did not feel at liberty to dissect it. Of that species, there- 
fore, I have been obliged to content myself with merely the general 
figure. 


thorace breviusculo, convexo, integro (i. e. vix canaliculato), ad latera leviter 
rotundato, ad basin utrinque (mox intra angulum) excavato ; elytris convexis, 
integris (nec nodosis nec costatis), transversim subtuberculato-rugosis (vix 
punctatis), versus basin et apicem obscure subrufescentioribus ; antennis pedi- 
busque rufo-ferrugineis.

This little Tarphius is smaller than any of the twenty-nine species as yet 
detected elsewhere, except the 7. Lowe? (from Madeira and Porto Santo),—the 
smaller examples of which descend to the size of the Sicilian specimen now be- 
fore me, for the opportunity of re-examining which I am indebted to the kind- 
ness of Professor Westwood. It is also remarkable for being sparingly clothed 
with rather long and fine suberect Aazrs, instead of the strong bristles which are 
more or less present in most of its Atlantic allies, and which are exceedingly 
robust in the Turphiodes from Southern India; and it has another peculiarity 
(which I had failed to observe until now, and which I can scarcely believe to be 
accidental), namely, that the base of its prothorax has a small excavation (which 
I had regarded as a mere impression in my diagnosis given in the ‘ Ins. Mad.’) 
on either side, just within the hinder angle. Its other characters consist in its 
oblong, subcylindrical, and convex body (its prothorax being particularly convex, 
and with only faint traces of a narrow central channel), in its fusco-piceous hue 
(there being merely a slight indication of suffused, ill-defined, subrufescent, cloudy 
blotches just perceptible towards the base and apex of its elytra), and in its elytra 
(which are quite parallel at the sides) being free from any indication of either 
nodules or ridges. In the figure given by M. Duval, in his excellent ‘ Gen. des 
Col. d@’ Europe,’ the elytra are not made sufficiently parallel; the ground-colour, 
also, of the entire insect is much too black, and the rufescent patches are im- 
mensely too red and defined. Germar’s admirable plate portrays all the cha- 
racters of the species far more accurately. Even that, however, does not indicate 
the elytral sculpture with sufficient precision ; nor does it notice the basal ex- 
cavations (if indeed they be not accidental in the example now before me) within 
either hinder prothoracic angle. Prof. Westwood’s type is from the collection 
of the late Mr. Melly, of Liverpool. 


Mr. T. V. Wollaston on the Tarphii. 375 


In the remaining portion of this paper I propose to describe the 
nine Tarphii which have hitherto been observed at the Canaries. 
On the special interest which attaches to that curious genus it is 
needless for me here to dilate; for, so far as the Madeiran and 
Canarian archipelagoes are concerned, it is not too much to say that 
there is no Coleopterous form more important geographically than 
Tarphius. Confined almost exclusively to the damp laurel-groves 
of intermediate and lofty elevations, where they may be found ad- 
hering to sticks and pieces of rotten wood, the members of it are no 
less remarkable for their numbers than they are for their inactive or 
sedentary modes of life; and I think I may safely add that I have 
never examined a single laurel-region in any of those islands with- 
out detecting one or more of the exponents of this anomalous group. 

Yet, though the head-quarters of Tarphius seem to be, unmis- 
takeably, in the intermediate zones of these mountainous sub-African 
islands, like most other forms topographically circumscribed, it would 
appear to be not altogether destitute of an outlying member or two 
in regions far removed from that which must be regarded as par ex- 
cellence its own; and, accordingly, until I commenced collecting in 
Madeira, in 1847, it was known to science by merely a solitary 
beetle of the utmost rarity—the 7. gibbulus from Sicily. While 
concentrated, therefore, to such an extent in the Atlantic islands, 
that, up to the present date, as many as nineteen well-defined re- 
presentatives have been discovered at the Madeiras and nine in the 
Canaries, we have the above-mentioned Sicilian one to account for: 
and I would wish here to state that it is these “‘ outlyimg members” 
of apterous, phlegmatic groups like Tarphius (totally removed, as 
they are, from all the contingencies of accidental diffusion) which 
offer the greatest difficulty to the hypothesis of those naturalists who 
believe that all species have been produced by an imaginary process 
of evolution, or the branching-off of erratic races in different (though 
each of them undeviating) directions from a parent stock. 

However optional this fancy may be, there would be at least nothing, 
so far, absolutely against it (but rather the reverse) if the species of all 
known genera on the earth’s surface were topographically associ- 
ated; for it is clear that where the ancestors have flourished, there 
for the most part will be found their descendants. Nor would I 
desire to ignore the fact, that on a broad scale this geographical 
grouping is pretty clearly indicated. But, unfortunately for the 
theory, there are just enough of insuperable exceptions to the rule to 
convince us that it is not universally applicable ; or, in other words, 
while most species whieh are nearly allied inter se range over the 


376 Mr. T. V. Wollaston on the Tarphii. 


same or contiguous tracts, almost every extensive assemblage has a 
few exponents which are apparently quite indigenous in regions ex- 
ceedingly remote from that which sustains the major part or 
nucleus. 

Now Tarphius is exactly in this predicament. Centred in the 
damp and often almost inaccessible forests and elevated Serras of 
the Atlantic islands, off the north-western coast of Africa, the 
various species are so sluggish in their habits, and so locally re- 
stricted, that but few of them have succeeded in tenanting more 
than a very small area—being frequently confined to a single 
ravine, or an isolated mountain-slope. And so adapted do they seem 
to be to those dense humid regions (where, as just stated, they may 
be found attached to the sticks and fragments of wet, decaying wood 
which strew the ground beneath trees of a fabulous age), and so 
unable to exist in arid spots of a lower altitude, that it is impossible 
to resist the conviction that no process of ordinary migration can 
have ever brought them to where they now are, and that they con- 
sequently occupy, even to this day, their actual primeval sites. As 
might be expected from this epitome of their modus vivendi, nearly 
every one of these islands in which the laurels still remain has its own 
Tarphii,—merely two species out of the twenty-eight hitherto dis- 
covered (namely, the 7’. Lowet, at the Madeiras, and the 7’. canariensis, 
at the Canaries) having apparently colonized more than a small portion 
of even their respective groups. If, then, these insects are so circum- 
scribed in their several ranges, and so difficult of dispersion (whether 
by their own means or casual ones) that they have not only failed 
to establish themselves in the various parts of their little archipela- 
goes, but have not extended over even their peculiar ¢slands—where, 
in both instances, all the conditions are present, and comparatively 
close at hand, which their necessities require,—it seems preposterous 
to conclude that the representative from so distant a country as 
Sicily can have belonged to the same community as its Atlantic 
allies. Yet,if the desire of naturalists to maintain a hopeless thesis 
should drive them still to that almost incomprehensible conclusion, 
I may add that, despite the close resemblance of this Sicilian Tar- 
phius to the Madeiran and Canarian ones—so close that they must 
needs be regarded as undoubted members of the same genus,—there 
is nevertheless sufficient difference between them to warrant the 
conviction (even in those who believe in the possible existence, with- 
in reasonable limits, of geographical sub-species, occasioned by the 
long-sustained action of surrounding influences) that they cannot 
have proceeded from the same stock. So that, whether viewed geo- 


Mr. T. V. Wollaston on the Tarphii. 377 


graphically or structurally, we may feel virtually certain that the 
two nuclei, although cast (so to speak) in the same mould, were ab- 
originally distinct. ‘Taking this therefore for granted (which I am 
satisfied that all candid observers who are acquainted practically 
with these creatures and their life-histories would do), I leave it 
to the advocates of the new hypothesis to decide how it is that in, 
at any rate, two remote parts of the world (Sicily and the sub- 
African islands of the northern Atlantic) independent organisms 
should have been slowly and systematically modifying themselves, 
through countless ages and under totally different circumstances, in 
so precisely the same undeviating direction that they have arrived 
ultimately at structures, complex and most peculiar, which are so 
nearly the same that they must now be treated as generically iden- 
tical. If this can be conceived possible through the operation of any 
mere “ selecting power of nature,” guided by chance agencies from 
without, it will be useless in future to bring forward any facts to 
confront the theory at all; and we must leave it to be ‘* demon- 
strated” by the less tedious and more poetical method of pure imagi- 
nation. 

Having been induced to touch upon this question of specific dis- 
tribution, as instanced by Tarphius and its outlying Sicilian member, 
I have taken the opportunity of dwelling upon it thus at length, not 
on account of any peculiarity in the example selected (which is but 
one out of hundreds of a similar kind, as every practical naturalist 
is aware), but simply for the sake of recording the particular con- 
siderations bearing upon a certain newly-revived (but by no means 
modern) doctrine, which one of the commonest classes of facts in 
geographical zoology has always seemed to me to be capable of 
directly engendering. And although I have purposely confined my 
remarks to members of the same actual genus—for I have desired to 
limit the problem to creatures which everybody will spontaneously 
acknowledge to be what, through the poverty of language, we con- 
ventially term “ nearly allied,”—I would nevertheless beg the reader 
to observe that they are equally applicable to all organisms which 
possess (¢nter se) great structural resemblance, whether or not they 
be so similarly constituted as to require a positive admission into 
what we call (often without much real precision, and very gratui- 
tously) the same “ genus.” So that if the above suggestions should 
carry with them any weight when applied to the absolute Tarphii of 
the Atlantic islands as compared with the representative from Sicily, 
the enormous interval between both of those regions and Southern 
India will @ fortiori impart to the pseudo-Tarphii of the latter a 


378 Mr. T. V. Wollaston on the Tarphii. 


right to elicit the same kind of reflections (bearing upon the absolute 
ones) with tenfold force. 

I would wish it to be particularly borne in mind that the foregoing 
remarks apply only to creatures which bear a close structural resem- 
blance to each other in countries far removed inter se, and have no 
reference whatever to the question as to whether or not any of the 
more nearly allied Madeiran and Canarian Tarphii may have been 
in their own respective provinces slowly brought about by some (so- 
called) “selective ” process acting uninterruptedly upon erratic races 
(albeit in a manner strangely unintelligible to us) so as gradually to 
intensify them. Although the lately revived hypothesis which would 
at once reply to the latter in the affirmative might be appropriately 
touched upon here, and although I might adduce, did space permit, 
the strongest reasons against the wnqualified acceptance of it, I 
nevertheless will not do so now: for such considerations come rather 
within the province of poetical speculation than of sober induction ; 
and it is hopeless to discuss them, seeing that we have not so much 
as a fragment of evidence to lead to their practical solution. Never- 
theless if it will afford any comfort to those who may perhaps differ 
from us, let us candidly admit that within narrow limits there seems 
nothing @ priort unreasonable in the supposition that such may possi- 
bly have been the case ; and moreover we can do this conscientiously, 
without compromising in the slightest degree the far higher doc- 
trine (which, on other grounds, we accept as absolutely true) of 
special creation. For to suppose that there are no modifying influ- 
ences at work (and often exceedingly subtle ones) in nature, would 
be almost as illogical as to assume that, because such exist, therefore 
they are all-efficient, and that no other “evolving [or creative] 
power” has ever acted, or can act, simultaneously with them. Such 
a conclusion as this latter one may suit the growing materialism of 
some of our modern “ philosophers,” the sum-total of whose belief 
is based in reality upon truths of sense, but it will not satisfy the 
craving after knowledge of those minds which are able to discern 
another class of truths in the world around us (and the most certain 
with which we are acquainted), for which mere “science” can 
afford no explanation. Truths such as these are called, by way of 
distinction, “‘ truths of reason ;” and (amongst others) it is a truth 
of the highest reason, that a natural law without a limit to its opera- 
tion is an absurdity. And therefore to argue that limits do not exist 
simply because (by the nature of the case) we cannot define them, 
is to confound two distinct classes of truth, and to treat a truth of 
reason as though it appealed directly to the understanding like a 


Mr. T. V. Wollaston on the Tarphii. 379 


truth of sense. But those who already acknowledge this twofold 
aspect of truth will accept the doctrine of limits, in a general 
signification, as embodying a principle not the less certain because 
incapable of actual demonstration ; and, accepting it generally, they 
will not feel themselves compelled to admit that all life has sprung 
from a single germ (the only logical conclusion of the transmuta- 
tionists, and not the “analogical ”’ one, as has been asserted), through 
the mere fact that a truth of pure reason is discovered to be, in its en- 
tirety, unproveable. 

I do not apologize for this slight apparent digression, as the reader 
will immediately perceive why I have been led into it. If we can 
establish the conviction that the doctrine of limits is (in the nature 
of things) essentially a reasonable one, we shall not be regarded as 
“inconsistent ” for holding variability to be an inherent principle 
(more or less expressed according to the elasticity of each individual 
species, and therefore strongly so in some, whilst it is scarcely trace- 
able in others*), and yet denying its existence, in all instances, eacept 
to a certain (a priort undefinable) eatent—an extent, however, which 
we may ascertain approximately by observation, leaving our reason 
to supply, from analogy, what sense (not being omniscient) is of 
course unable, at a single glance, to take in. 

But lest I should be accused of merely theorizing, and of insisting 
upon old scholastic definitions which it is the fashion now-a-days (at 
least in those who have not studied them) to regard as obsolete, and 
since, if there be any reality in the distinctions which I have dwelt 
upon, they ought to bear the strictest analysis, it will not be con- 
sidered irrelevant, even in the present paper, if we test them by the 
most common-place example we can select. Let us take, then, the 
genus Homo. It is quite impossible to define rigidly the exact 
growth of the human species. No amount of observation will tell 
us either its maximum or its minimum. Nevertheless, in spite of 
this, we are perfectly certain that its bounds are strictly circum- 
seribed; for it is a matter of plain reason (of which we are as sure 
as we are of our own existence) that no man will ever attain the 
height of the monument, and likewise that no one was ever so small 
as the fabled denizens of Lilliput. Yet we cannot prove this. And 
why? Because it is merely a “truth of reason.” We can take a 


* The domestic pigeon, in its various artificial phases, may be cited as a good 
instance (not entirely, perhaps, an original one) of the former category ; whilst 
the common Lady-bird (Coccinella 7-punctata), which occurs in nearly every 
country of the Old World, and at all elevations, without the slightest appreciable 
change in its specific characteristics, will suffice as an instance of the latter. 


380 Mr. T. V. Wollaston on the Tarphii. 


number of men and measure them (say by hundreds or thousands), 
and we can then prove, to an ocular demonstration, the precise limits 
between which they have varied in their stature ; for this isa “ truth 
of sense.” But is it, on that account, one jot more certain than the 
other? Most decidedly not. And hence we arrive at the convic- 
tion that the limits are not the less real because (by the nature of 
the case) we cannot prove them, and that to dispute their existence 
merely on the latter account, so far from being “ philosophical,” is 
simply foolish. If they are to be objected to at all, our philosophers 
must entrench themselves on more logical ground than this. But 
there is a point yet to be noted. A mathematician, in ascertaining 
the limit of a “variable,” treats it as a single function. Not so, 
however, the physiologist; for his “ variable” is an organism, 
which itself consists of many variables. The “ growth,” to which 
we have just alluded, is only one of them. But, nevertheless, pre- 
cisely the same reasoning wll apply to each one separately ; and after 
having reasoned them out in a similar manner, if we add up the 
several results we have arrived at, we may assert broadly, without 
fear of refutation, that the same veason which assures us that the 
growth of the human species is limited, assures us also that his other 
functions have likewise their respective limits (even though we cannot 
define them), and that, consequently, (to take no wider margin) he 
neither sprang from an ape, nor will be developed into an angel. 

Now these considerations will illustrate our meaning (albeit perhaps 
somewhat grotesquely) when we insist on the reality of limits, as an 
abstract truth. And let it be well noted that the admission does not 
imply any verdict against specific variation; it merely affirms that 
the limits of that variation are prescribed, and that it is illogical to 
argue that they do not exist, because (in the nature of things) we 
are of course unable to trace them rigidly out. No doubt in some 
instances the range for permitted variation may be, as lately stated, 
very great, whilst in others it may be reduced almost to zero—de- 
pending, in every case (as practical naturalists are well aware) on 
the inherent pliability of the particular species. But these are points 
which, even allowing for our imperfect judgment, may usually be 
determined approaimately by patient observation ; and we should 
remember that when we have done this we have done all that it is 
possible to do with our limited faculties,—the approwimate result 
being, for us, to all intents and purposes, the actual one. 

In the above illustration, borrowed from the growth of the human 
species, it is needless to remark that we might have reduced the 
distance between the supposed limits very considerably, and yet 


Mr. T. V. Wollaston on the Tarphii. 381 


have treated them equally as a truth of reason. But this was un- 
necessary, for I am not now discussing the question as to where the 
several lines of demarcation are to be drawn, but am simply assert- 
ing the broad fact that they have an abstract existence somewhere, 
rigidly and positively defined. For, in arguing the reality of limits, 
it must not be supposed that it is with any hope of making it easier 
to define practically where the boundary lines are to be placed. That 
is altogether another matter, and one which must be solved approxi- 
mately by a careful and laborious investigation, for it cannot be 
arrived at by dialectics; and we must be content therefore, gene- 
rally, to leave it in the hands of those naturalists who have devoted 
their lives to the investigation of the particular groups. With our 
short-sighted faculties, indeed, the limitation of species always will 
and must be, in a great measure, subject to dispute; for our powers 
of judgment differ, and are not stereotyped: but to use that fact as 
an argument against the existence of limits altogether is in the 
highest degree unphilosophical, and can only result from a misappre- 
hension of the class of truth to which they necessarily belong. 

Tf, then, I had to sum up in a few words what has been said, it 
would be to the effect, that these Atlantic and Sicilian Tarphii, 
with their “nearly allied” Indian representatives, were, and must 
have been, as nucle?, aboriginally distinct. Whether we view them 
structurally or geographically, this conclusion is alike forced upon 
us by evidence which it seems impossible to resist,—whilst there are 
the strongest reasons for suspecting that the modern theory which 
would pretend to derive them all from a common ancestor, so far 
from being a philosophical one, is based upon a fallacy and an 
ignoring of the distinction between two opposite classes of truth. 
To render this latter fact the more obvious, I have endeavoured to 
show that the doctrine of limits is not a mere concoction of the 
brain, but that it embodies a reality which no amount of sophistry 
or ingenious special pleading can set aside, and that it is not the 
less to be believed because, like half the truths of which the human 
mind is cognizant, it is a “truth of reason,” and therefore not 
proveable, in its entirety, to our imperfect understanding, like a 
truth of sense. As for the question (and it is an exceedingly inter- 
esting one) of limited modification from external influences of every 
kind, we may safely leave it to be decided on its own merits; but 
let us be very cautious how we employ the results arrived at in this 
restricted field of research to subvert fundamental principles, which, 
if they are to be assailed at all, must be approached in a different 
manner and from a totally different direction, and which would 


382 Mr. T. V. Wollaston on the Tarphii. 


probably require an @ priori treatment rather than an d posterior 
one. Principles such as these, which have been regarded hitherto 
as axioms, are strictly “truths of reason,’ and rest upon too broad 
a basis to be affected by our deductions (often very equivocal ones) 
from a few isolated facts which may appear at first sight to contra- 
dict them, and which may generally be met by an equal number of 
“facts ’’ (so-called) telling, or seeming to tell, a precisely opposite 
tale. They belong rather to the very foundations of our belief, and 
must be examined by analyzing our own minds. So that, if we 
would sift this problem satisfactorily, we must needs begin with the 
most elementary considerations; for otherwise all subsequent argu- 
ments, however carefully conducted, will only lead us deeper into 
error, since it is clear that, if we set out with our backs upon the 
truth, the further we go the more we shall recede from it. 


The following nine Tarphii (which I propose now to describe) are 
peculiar to the Canaries, and were detected during my explorations, 
in company with the Rey. R. T. Lowe, in those islands. Probably 
there are many species yet to be discovered ; for the extensive sylvan 
range on the western side of Hierro I have but just glanced at, whilst 
the laurel-districts of Gomera and the remains of the ancient forest 
of E] Dorames in Grand Canary are totally unexamined.

The rather narrower and more strictly oblong outline of the present 
Tarphius, in conjunction with its somewhat long and narrow pro- 
thorax (which is scarcely at all expanded in the middle or constricted 
behind), and its comparatively undeveloped and usually more or less 
obscurely subrufescent elytral nodules, and the tendency of its elytral 
tubercles to be more decidedly arranged in longitudinal rows, will at 
once separate it from the other species here described. It is not un- 
common within the laurel-districts of Teneriffe; I have taken it at

Only two specimens of this Zarphius, taken by myself in the 
laurel-woods of El Golfo, on the west of Hierro (during February 
1858), have come hitherto beneath my notice. Its large size and 
obtuse though much developed nodules, in conjunction with its 
rather long prothorax (which is wide in the middle and gradually 
narrowed behind) and its short and almost decumbent sete, will 
sufficiently characterize it. It is more akin to the 7’. canariensis 
than to any other species here enumerated; but it is distinctly 
larger, its prothorax is more developed and less suddenly narrowed 
posteriorly, its colour is altogether darker, its nodules are more 
prominent, its antenne are a little more robust, and its sete (instead 
of being erect) are nearly decumbent.

T have also taken it, though sparingly, at Osorio in Grand Canary, 
and in profusion throughout the sylvan districts of Palma. It may 
be known by its prothorax being more or less suddenly narrowed 
behind, by its nodules being tolerably developed and at times ob- 
scurely rufescent, and by its sete being short and suberect. The 
Palma specimens (var. (. affinis) are just perceptibly narrower and 
less flattened than those from Teneriffe and Grand Canary, and have 
their sete a trifle longer, darker, and less thickened, their prothorax 
a little more scooped-out behind (and with the posterior angles 
usually rather more prominent), their elytral nodules rarely diluted 
in colouring, and their antenne perhaps, if anything, somewhat 
shorter; but I do not think that they can be regarded as more than 
a mere phasis of the 7’. canariensis.

Did not the present Tarphius occur in company with the 7’. 
canariensis, I might have almost supposed it to be but a local state 
of that insect; nevertheless, since the two are found absolutely 
together, and exposed therefore to the same influences, I think that 
the 7’. erosus must be properly regarded as distinct. Nor can the 
slight constant differences which characterize it be looked upon as 
sexual ones, seeing that in Palma, where the 7. canariensis actually 
abounds, the erosus has not yet been observed even to exist. It may 
be known from its ally by being, on the average, a trifle smaller and 
more depressed, by its prothorax being still more suddenly constricted 
behind, by its elytral nodules being slightly less developed and usually 
much more decidedly rufescent, and by its limbs being generally just 
perceptibly longer and paler. It is not uncommon in the laurel- 
woods of the north-eastern district of Teneriffe, where I haye taken 
it, in company with the 7’. canariensis and simplex, at Las Mereedes 
and above Taganana.

The nearly square outline and rather elongate suberect sete of 
this broad Tarphius, added to the usually brown scales with which 
it is clothed, its laterally (and equally) rounded prothorax, and the 
tolerably large and slightly rufescent nodules of its apically incurved 
(or suddenly truncate) elytra, will at once characterize it. So far 
as I have observed hitherto, it is peculiar to Palma,—where in May 
and June of 1858 I took it sparingly, beneath sticks and pieces of 
rotten wood, in the laurel-district above Buenavista, on the ascent 
to the Cumbre, as well as towards the upper region of the Barranco 
de Galga.

The present and three following Zarphii differ from the preceding 
five in being less evidently setose ; though the 7’. congestus has a 
coarse, but sparing, decumbent golden pile, which is rather conspicuous 
on its remarkably dark surface. The present species is one of the 
most distinct of the whole,—its short, compact body, and small, 
abbreviated prothorax (which, although narrower there than the 
elytra, is broadest at the extreme base, and from thence gradually 
contracted to the apex, like the arc of a circle), in conjunction with 
its very short antenne and posteriorly incurved, or shortened, elytra 
(as in the 7’, quadratus), giving it a character quite its own. As in 
the 7’. gigas and caudatus, its anterior prothoracic angles are more 
acute than in the other Canarian Zarphii here described ; and yet, 
in spite of this, the front emargination of these three species (par- 
_ ticularly, however, of the present one and the 7. caudatus) is con- 
siderably shallower than is ordinarily the case. The 7. congestus

is both exceedingly rare and local,—the only specimens of it (24 in 
number) which have as yet come beneath my notice having been 
captured by myself, during May of 1858 and the following year, in 
the woods of the Agua Mansa of Teneriffe.

This is the largest species of Zarphius which has as yet come 
under my observation ; and, apart from its comparatively gigantic 
bulk, it may be recognized by its broad, thick, squarish-oblong form, 
by its rather piceous and obtusely-nodose surface, as well as by its 
‘elytra having their disk somewhat horizontal (though less so than 
in the 7’. caudatus), and their extreme apex rather drawn out or 
acuminate. Its prothorax is subsemicircular in outline, being 
broadest about the middle, and but very slightly narrowed behind. 
It is apparently of the greatest rarity,—the only two specimens 
which I possess having been captured in the dense and elevated 
laurel-region between Taganana and Point Anaga, of Teneriffe, 
during May of 1859. 


8. Tarphius caudatus, n.sp. (Pl. XIX. fig. 8.)

This most remarkable Tarphius may be instantly known by the 
broad (though posteriorly emarginate) lobe into which the extreme 
apex of its elytra is produced,—forming a kind of blunt, squarish 
tail. Its surface, also, is rather darker than that of any of the | 
other Canarian Tarphii, except the 7. congestus ; and it is likewise 


Mr. T. V. Wollaston on the Tarphi. 387 


somewhat less clothed with scales (being even a little shining), and 
almost free from any appearance of sete. Its elytra, however, are 
greatly roughened (as it were with immense subconfluent punctures), 
with their disk very horizontal, but with the lateral and posterior 
nodules and costé (particularly the latter) greatly developed. Indeed 
the tail-like process is absolutely formed by the enlargement of the 
two hinder subsutural ridges, which (projecting entirely to the apex) 
are lengthened outwards, thus not only elongating the apex itself, 
but causing it also to terminate in this bipartite lobe. Its prothorax 
is of a rather peculiar shape—the widest portion being a little before 
the middle, whilst it is nearly straight behind, but suddenly incurved 
in front. I did not observe this Tarphius during my first visit to the 
Canaries; but in June 1859 I took it rather abundantly beneath 
sticks and pieces of rotten wood in the laurel-regions from Las 
Mercedes to the Cumbre above Point Anaga, especially in the thickest 
parts of the forest on the descent by the Vueltas to Taganana. 


9. Tarphius deformis,n.sp. (Pl. XIX. fig. 9.)

rufo-ferrugineis. 

Long. corp. lin. 13-2. 

Habitat in sylvaticis editioribus Teneriffe, late diffusus sed rarissimus. 
The 7. deformis is not only remarkable for the extraordinary 

development of its nodules and ridges (the latter of which project 
enormously on the hinder region of the elytra), but it may likewise 
be known by its large prothorax (which is very wide, and obtusely 
- rounded, in front, but gradually narrowed to the base), by the 
immense, brownish (and sometimes cinereous) scales with which it 
is densely clothed, as well as by its much porrected shoulders, free- 
dom from sete, and by its rather abbreviated antenne. Its elytra, 
too, are generally just perceptibly narrowed from the base to the 
apex, which is not the case in the other Canarian Yarphii here 
enumerated. It is decidedly rare, and apparently peculiar to Tene- 
riffe,—the only specimens which I have seen (16 in number) having 
been captured by myself, during 1859 and the following year, in the 
laurel-woods of the Agua Mansa and the Agua Garcia, as well as in 
those above Taganana and Point Anaga.

XXVIII.—WNotes on the Brenthidee. 
By Francis P. Pascon, F.L.S., &e. 


Most of the Brenthide described in these notes are due to Mr. 
Wallace’s indefatigable researches in the Indian Islands, where they 
seem to abound. There are still materials, however, for a very con- 
siderable addition to our knowledge of this family ; and, considering 
their bizarre forms and the doubtful place which they occupy in 
classification (evidently, however, a transition group), it is somewhat 
remarkable that so little should have been written concerning them. 
It is not my intention just now to do more than indicate some of 
these novelties ; but, to those which we owe to Mr. Wallace, I have 
added another form from South Africa, which bears such an evident, 
although perhaps somewhat distant, resemblance to Hypocephalus, 
that I cannot help regarding Mr. Curtis’s idea* that the latter is a 
gigantic Brenthus as much nearer the mark than his latest opinion, 
which refers it to the Zamellicornia! In the following pages the 
descriptions only apply to the males,—the females, as is well known, 
differing principally in the simple terete rostrum and basal insertion 
of the antenne. 


Ecrocemuts. 


Caput parvum, postice sublobatum, collo brevissimo, oculis subbasalibus. 
Rostrum elongatum, canaliculatum, basi rugosum, apice abrupte alatum, 
mandibulis parvis exsertis. Antenne longiuscule, teretes, articulis 
secundis tertiisque subequalibus. Prothorax subovato-ampliatus, levis. 
Elytra breves, subtriangulares, apice quadricallosa. Pedes mediocres, 
antici elongati, femoribus dentatis, tibiis anticis subcurvatis, apice 
spinosis, tarsis brevibus. 


In some respects this genus approaches Arrhenodes, although in 
habit it is more like Rhaphirhynchus ; but the form of the head, the 
smallness of the mandibles, and, above all, the peculiar rostrum are 
sufficiently distinctive. 


Eciocemus Wallace. 
£. rufo-ferrugineus ; elytris nigris, flavo lineatis, fortiter punctato-striatis, 
apice angulatis. 
Hab. Batchian. 

Head and rostrum about one-third the total length, the former some- 
what bilobed and smooth behind the eyes, black, the neck indistinct, 
rostrum slightly narrowing to the middle, where it receives the an- 
tenne, black, and rugosely punctate, beyond the antenne gradually

Mr. F, P. Pascoe on the Brenthide. 389 


rising on each side into a short, vertical tooth, the apex, including one- 
third the rostrum, ferruginous, gradually expanding at the side, and 
terminating in a horizontal triangular wing, within the margin on each 
side, but not continued to the apex, an elevated line crowned with five 
teeth ; antennz ferruginous, about two-thirds the length of the body, 
the joints, except at the base, nearly terete, and longitudinally corru- 
gated; eyes small, round; prothorax impunctate, yellowish ferruginous, 
shining; elytra black, roughly punctate-striate, with an interrupted 
yellow line near the suture, another line sometimes externally, the 
apex slightly divaricate, then truncate, each angle of the truncated 
portion furnished with a small callosity; legs ferruginous, nearly 
smooth, shining, all the femora clavate, the anterior longest, beneath 
and towards the apex an oblique acute spine, anterior tibiz dilated 
beneath, the apex with a strong exterior spine; body beneath yellowish 
ferruginous, smooth, shining. Length (with rostrum) 12 lines. 


The female has the antennz shorter and inserted near the base of 


the rostrum, which, from that point, is round, smooth, and nearly 
linear. 


It seems to me desirable to separate from the great genus Arrhenodeg 
those species with a slender, comparatively elongated rostrum, head 
abruptly excised almost directly behind the eyes, and very small 
mandibles; the latter organs, indeed, if contrasted with those of 
Arrhenodes, seem to indicate a very considerable difference in their 
economy. I have named this group Orychodes; and it will include 
_Brentus serrirostris, Fab., Arrhenodes digramma, Bois., and some 
new species, one of which I have described below. 


ORYCHODES. 


Caput breve, pone oculos excisum, collo brevissimo. Rostrum mediocre, 
tenue, apicem versus dilatatum, angulatum, subtus costatum ; mandi- 
bulis parvis. Antenne mediocres, articulis inferioribus obconicis, ex- 
terioribus subcylindricis, prope medium rostri inserte. Prothorax 
elongato-ovatus, haud canaliculatus. lytra subcylindrica.  Pedes 
robusti, antici longiores; femora dentata ; tibize curvate ; tarsi brevius- 
culi. 

Orychodes pictus. 

O. nigro-piceus, nitidissimus; capite postice mutico; prothorace valde 
elongato ; elytris luteo maculatis; femoribus medio lete luteis. 

Hab, Batchian. 

Subdepressed, pitchy black, very smooth and glossy; head very short, 
abruptly excised directly behind the eyes, without any spine; rostrum 
shorter than the prothorax, thickish and smooth at the base, canalicu- 
late above to nearly the insertion of the antenne, where it has a

rounded impression, beyond this it becomes quadrangular, and widens 
eradually to the apex, with the upper angles serrated, and the space 
between sprinkled with oblong granules, beneath the rostrum a longi- 
tudinal costa; antenne as long as the prothorax, inserted behind the 
middle of the rostrum, the four basal joints obconic, the remainder 
subcylindrical ; prothorax elongate-ovate, nearly as long as the elytra ; 
elytra short, parallel, with three longitudinal bright-luteous spots on 
each, the apex entire; legs rather robust, the anterior largest, femora 
clavate and toothed beneath, bright-luteous yellow, except at the ex- 
tremities, tibie short, curved, spined at the apex, the anterior hollowed 
out internally towards the apex, and clothed with golden-yellow hairs, 
tarsi rather short, stout; the last three abdominal segments clothed 
with golden hairs at the side. Length 10 lines. 


ITHYSTENUS. 


' Leptorhynchus, Guérin (1830), non Clift (1829). 


The species of this genus are among the longest and narrowest of 
the Brenthide, and have all so much in common, that a minute 
*description of each would be little more than a repetition; at the 
same time it is only by comparison that they can be, with any 
degree of certainty, understood. They have all the same dark-brown 
colour, varied in some by a yellow line on each elytron, and the base 
of the femora paler than the clavate portion, but this is not always 
even specifically constant. Individually they vary remarkably in 
size (6 to 20 lines), and in some instances in the proportional length 
of their parts. Except the original J. angustatus, none of them have 
the beautiful fringe of hairs beneath the four posterior tarsi which 
characterizes that species; or rather it is so much reduced as to cease 
to be remarkable. In J. ophiopsis only the prothorax is bent down, 
almost as if broken. Of the remainder, J. angustatus, I. Wallacei, 
and I. frontalis have a yellow stripe on each elytron, which does not, 
however, quite attain to the apex. J. linearis has a red spot at the 
base of each, while J. fwmosus is entirely unicolorous, at least as to 
the elytra. 


Ithystenus Wallace. 


I. nigro-fuscus ; capitis fronte integra, rostro elongato tenui canaliculo; 
elytris luteo bivittatis, spina exteriore crassa, conica, paulo curvata. 
Hab. Mysol. 


Differs principally from J. angustatus in the elytra not dilated at 
the external angle of the apex, but prolonged into a short, thick, 
conic process slightly curved externally. 


Mr. F. P. Pascoe on the Brenthide. 391 


Ithystenus frontalis. 

I. nigro-fuscus ; capitis fronte canaliculata; rostro basi profunde canali- 
culato; elytris late bivittatis, spina exteriore cylindrica, apicem versus 
acuta. 

Hab, Aru. 


_ Very like the last, but less elongate. The narrow groove extending 

the whole length of the head and running into the broad canal at 
the base of the rostrum, where it gradually spreads» out and is 
obliterated at about a quarter of its length, affords good diagnostic 
characters when compared with the same parts in J. Wallacei, where 
the head is entire, and the rostral canal is uniformly narrow, and 
continued as far as the insertion of the antenne. The apical spine 
in this species is cylindrical, except at the tip, where it suddenly 
becomes conic and pointed. 


Ithystenus fumosus. 
ZI. nigro-fuscus; capitis fronte late canaliculata, transversim corrugata ; 
elytris concoloribus, spina exteriore filiformi, elongata. 
Hab. Batchian. 

In some individuals of this species the posterior margin of the 
prothorax is of a deep blood-red, or the bases of the femora are 
nearly of the same colour ; but it is well distinguished by having on 
each side of its frontal canal a finely sculptured series of transverse 
hair-like plaits. The elytra are entirely dark brown, and the apical 
spine is unusually long for this genus, its length being about twice 
the breadth of the elytra. 


Ithystenus linearis. 


I, nigro-fuscus ; capitis fronte tenuiter canaliculata; elytris basi rubro 
maculatis, spina exteriore brevi, subconica. 
Hab. Batchian. 


The short, conic, apical spine and the clear blood-red spot at the 
base of each elytron, almost confined, however, to the base of the 
third of the raised lines, where it seems to replace the longer yellow 
line of J. angustatus, &c., will readily distinguish this species from 
any here destribed, 

Ithystenus ophiopsis. 


I. nigro-fuscus; prothorace antice curvato; elytrorum spina exteriore 
_ brevi, incrassata, compressa. 
Hab. New Guinea (Dorey). 


The curved prothorax, presenting a sort of gibbosity above, and 


the short, stout, deeply compressed spine of the elytra, are characters

confined to this species. It is uniform in its colour, and, after J. 
angustatus, is the largest and proportionally the most attenuated 
of the genus. 

PRODECTOR. 


Caput quadratum, collo brevissimo. Rostrum elongatum, vix canalicu- 
latum, basi dilatatum. Antenne mediocres, subfiliformes, versus 
apicem rostri inserte, articulo secundo primo longiore. Prothorax 
subdepressus, canaliculatus, antice angustus, lateribus ampliatus. E/ytra 
lineares, appendiculata. Pedes tenues, femora haud clavata, mutica, 
tibiee sublineares, tarsi angusti, articulo basali elongato. 


Nearly allied to Diurus, from which it is well distinguished by the 
dilated apex of the rostrum, the length of the second joint of the 
antenne, and the canaliculate prothorax. 


Prodector laminatus. 

P. niger, opacus, sparse albo hirtus; elytris seriatim punctatis, lineis 
duabus albis ornatis, apice productis, appendiculo longo laminato ob- 
tuso. 

Hab, Menado. 

Elongate, black, opake, with scattered, white, short, scaly hairs ; head 
narrowly quadrate, rostrum about five times its length, very slender, 
obsoletely canaliculate, the apex dilated, shining, and coarsely punc- 
tured ; eyes small, black; antennze not so long as the rostrum, nearly 
filiform, inserted near the apex, the second joint longer than the first ; 
prothorax less than half the length of the elytra, depressed, narrow in 
front, enlarged at the sides, broadly canaliculate above; elytra parallel, 
regularly seriate-punctate, a line of white hairs on each, near the suture 
the apex produced into a long, lanceolate, obtuse lamina ; legs slender, 
of moderate length, tibiee nearly straight, shortly spined at the apex, 
tarsi narrow, the basal joint elongate. Length 21 lines. 


Varies in the length of the caudal appendage (which, in the 
specimen from which the above description was made, was nearly as 
long as the elytra), as well as in size and relative proportions. 


Diurus of Dejean still remains, I believe, a mere catalogue name, 
although it has been many years proposed, and is well known as 
designating one of the most extraordinary of this extraordinary 
family ; the following are the principal characters of the genus :— 


Divrtvs. 


Caput tenuissimum, vix rostro crassius. Rostrum elongatum, subcylin- 
dricum, apice haud dilatato. Antenne mediocres, subfiliformes, articulo 
secundo parvo, versus apicem rostri insert. Prothorax supra convexus, 
antice angustior, haud canaliculatus. Hlytra linearia, appendiculata.

Pedes tenues ; femora haud clavata, mutica; tibie graciles, breviuscule ; 

tarsi mediocres, articulo basali subelongato. 

Type Ceocephalus furcillatus, Schon. Gen. et Spec. Curcul. i. p. 359 
(Diurus forcipatus, Westw.). There is a second species for which I 
cannot find any satisfactory character that will distinguish the male, 
but whose female is decidedly different from the female of D. fur- 
cillatus. As neither of these have been described, I have placed the 
differential characters side by side, so that the peculiarities of each 
will be seen at once. I have applied the name of dispar to this 
species, which is from Borneo. 


Diurus furcillatus (@ ). 


Head moderately long, eyes 
two or three times its diameter 
from the posterior angle; an- 
tennze inserted between the 


middle of the rostrum and its - 


base; rostrum subelongate, gra- 
dually tapering to the apex, the 
part beyond the insertion of the 
antennz smooth and glossy; 
elytra at the apex narrowed and 
abruptly depressed, each termi- 
nating in a stout, subcylindrical 
process. 


Diurus dispar (2). 


Head short, eye only Once its 
diameter from the posterior an- 
gle; antennz inserted near the 
apex of the rostrum; rostrum 
short, thick at the base, abruptly 
narrowed beyond the insertion of 
the antenne, from thence to the 
apex rough (comparatively) and 
opake ; elytra scarcely narrowed 
at, but sloping rapidly to the 
apex, which is truncate, with a 
short slender spine at each outer 
angle. 


Mrorispa. 


Caput subquadratum, basi truncatum, collo brevi. Rostrwm breve, arcua- 
tum, basi trisulcatum, apice dilatatum ; mandibulis exsertis. Antenne 
breviuscule, incrassatee, versus medium rostri inserte ; articulis exte- 
rioribus transversis, secundo unilaterali, basi constricto, tribus ultimis 
majoribus perfoliatis. Prothorax oblongo-ovatus, anterius angustior, 
convexus, levis. Elytra subbrevia, subcylindrica, apice mutica. Pedes 
breviusculi, antice longiores ; femoribus tibiisque muticis; tarsis bre- 
vibus. 


Trachelizus appears to be the nearest ally of this genus, from which 
it differs principally in the form of the head, in the rostrum, antenne, 
and the non-canaliculate prothorax.

the antenne only black, or pale brown; the legs fulyous, with the 
tibio-femoral articulation black or dusky brown, the tibize and tarsi 
more or less ringed with black or dusky, the sutural region dark ferru- 
ginous, the sides also sometimes ferruginous ; head subquadrate, smooth, 
convex, rostrum less than twice the length of the head, curved, the 
basal half trisuleate, the intermediate sulcation extending to the apex, 
which is triangularly dilated, mandibles small, exserted ; eyes round, 
situated near the base of the rostrum; antenne short, thick, inserted 
at the middle of the rostrum, the second joint curved externally, the 
inner side near the base deeply constricted, the rest to the eighth inclu- 
sive shortly triangular, the last three joints larger and perfoliate ; 
prothorax oblong-ovate, smooth ; elytra rather short, subcylindrical, the 
apex entire, deeply punctate-striate, the inner stria without punctures ; 
leos short, anterior pair longer, femora and tibiee unarmed, tarsi short, 
robust. Length 31 lines. 


ZEMIOSES. 


Caput quadratum, convexum, collo bulbiformi. Rostrum crassum, brevis- 
simum, apice emarginatum., Antenne incrassate ; articulis transversis,

angustior, utrinque profunde impressus. lytra oblongo-ovata, com- 
pressa. Pedes mediocres ; tibize brevissime, apice spinosze, anticee intus 
dentate ; tarsi breves, compressi, subtus ciliati. 


Evidently allied to Taphroderes and Cyphagogus, from which it 
will be at once distinguished by the short, thick rostrum; from 
Calodromus* it differs principally in its short and differently formed 
posterior legs. 


Zemioses porcatus. 


Z. piceus; elytris striis elevatis, interstitiis transversim costatis. 
Hab. Natal. 

Pitchy ; head reddish ferruginous, short, quadrate, convex in front ; 
neck bulbiform; eyes round, moderately prominent, basal; rostrum 
short, thick, deeply emarginate or excavated at the apex; mandibles 
small, transverse ; antennee about as long as the prothorax, thickened, 
perfoliate, arising from a deep sinus below the eyes, the two basal joints 
shortly obconic, the remainder to the eighth inclusive shortly transverse, 
the last three forming a pointed club; prothorax smooth, shining, 
ventricose at the base, compressed and narrowed anteriorly, a deep im- 
pression at the side, apparently for the reception of the femur and tibia ; 
elytra narrowly oblong-ovate, compressed, with several strongly elevated 
lines, the interstices, except near the suture, transversely ribbed ; legs 
reddish ferruginous, femora clavate, unarmed, tibize very short, spined

XXIX.—Deseriptions of new Species of Mexican Pompilide, belong- 
img to the Genera Pompilus, Agenia, Priocnemis, Notocyphus, 
and Ferreola. By Freprricx Surru. 


In the tribe of fossorial Hymenoptera there is no family that contains 
species so elegant in their forms, or that are more splendidly adorned 
than are to be found in that of the Pompilide. These insects have 
an almost universal geographical range; but it is in Mexico and 
Brazil that the most beautiful species are found: every variety of 
colour, combined frequently with the brilliant effulgence of gold and 
silver adornment, are there to be met with. The species described 
in the present paper constitute an important addition to our know- 
ledge of the group, as not more than six or eight species have, to 
my knowledge, been previously described from Mexico. 


Family Pompilide, Leach. 


Genus Pompitus, Fabr.

This is one of the most beautiful species of the family Pompilide. 
The variety of its colouring, the brightness of the silvery pile that 
covers the legs and other portions of the body, and its mottled wings 
readily distinguish it from every known species of the genus. 


XXX.—Catalogue of the Dytiscidee and Gyrinide of Australasia, 
with Descriptions of new Species. By the Rev. Hamter Crank, 
M.A., F.L.8. 


I propose, in this and a subsequent paper, to notice the genera and 
species of the Dytiscide and Gyrinide that are at present known to us 
as inhabitants of Australasia—bringing together the few species that 
have been described already by authors, and adding descriptions of 
such new species as I have been able to examine, through the kindness 
of Dr. Gray of the British Museum, Mr. Bowring, Mr. Waterhouse, 


400 Rev, H. Clark on the Dytiscidee 


and, especially, Mr. Bakewell. The following pages will include, pro- 
bably, nearly every species that has as yet been brought in collections 
to this country. It will be seen that nearly all that we know as yet 
of the fauna of that vast continent is furnished by the neighbour- 
hood of Melbourne, which has been so carefully examined by Dr. 
Howitt and Mr. Bakewell. 


Family Dytiscide. 
Tribe I, HaLrpLipZ#. 
Genus Hauiptvs, Latr. - 


1. H. testudo, n. sp. 


H. ovatus, subelongatus, pallide ferrugineis ; thorace antice constricto, ad 
basin et antice fortiter nigro punctato ; elytris nigro striatis ; antennis 
pedibusque pallide furrugineis. 

Long. corp. 2 lin., lat. 1 lin. 

Ovate, somewhat elongate, convex, of a pale-ferruginous colour: 
head narrow, subelongate, impunctate; eyes large: thorax transverse, 
at the base nearly twice the breadth of the medial length, the sides are 
very slightly rounded, and very much constricted towards the front; 
the surface at the base is medially somewhat depressed, and impressed 
with two or three irregular rows of coarse black punctures; the an- 
terior margin is also medially more or less distinctly punctured : 
elytra ovate, the outline being broadly dilated near to the thoracic 
angle (the greatest breadth being in front of the middle of the insect) ; 
the surface is marked by ten deeply punctured striz, of which eight 
are perceptibly marked by dark lines from the apex to the base (the 
two lateral strie being uncoloured): Jegs and antenne pale ferru- 
ginous. 

H. testudo may be separated from H. australis by the manifest 
coloration of the thoracic punctures and also of the striz of the 
elytra ; in H. testudo the interstices between the striz are levigate, 
and not sparingly punctate as in H. australis. 

This species does not appear to be abundant. The four examples 
before me (all fairly uniform in colour and striation) are from the 
neighbourhood of Moreton Bay. 

In the collections of the British Museum, Mr. Bakewell, Mr. 
Waterhouse, and the Rev. Hamlet Clark. 


2. H. australis, n. sp. 


H. ovatus, convexus, subelongatus, pallide flavus ; thorace antice con- 
stricto, ad basin et antice punctato; elytris punctato-striatis et inter 
strias punctatis ; antennis pedibusque flavis. 

Long. corp. 14-2 lin,, lat. 1 lin. 


and Gyrinide of Australasia. 401 


Ovate, convex, somewhat elongate, of a pale-flavous colour: head 
subelongate : thorax considerably constricted in front, more so than in 
H. testudo; at the base the breadth is twice the medial length, the 
surface is subglobose, and thickly punctate both in front and along the 
line of the base (the punctures being very slightly darker in colour 
than the surface, and not decidedly fuscous as in HZ. testudo): elytra 
convex, considerably broader in front than the base of the thorax, the 
shoulders being somewhat more prominent than in the preceding 
species ; from the base to the apex are eleven coarsely punctate strie 
(the eleventh being in one example almost obsolete) ; the punctures are 
in colour very slightly fuscous, while between the striz are distinctly 
apparent irregularly arranged punctures: /egs and antenne@ flayous. 


This pretty species approaches nearly to H. testudo: it is mani- 
festly separated by its form (the humeral angles being more di- 
stinct) and by the character of the punctuation of the thorax and 
elytra. Both species entirely differ from species known to me from 
other continents. 

Of the three examples before me of this species, one is from the 
collection of the British Museum (the precise locality being unre- 
corded), and two I received some years ago from Mr. Stevens, the 
locality being “‘ South Australia.” 


3. H, fuscatus, n. sp. 


H. ovatus, subcylindricus, rufo-fuscus: thorace ad basin fortiter depresso, 
punctato; elytris ad humeros latis, leviter punctato-striatis, punctis 
rufo-fuscis (haud ut in H, gibbo nigro coloratis); antennis pedibusque 
rufo-fuscis. 

Long. corp. 14 lin,, lat. } lin. 

Ovate, broad, somewhat cylindrical, attenuated towards the apex, 
of a rufo-fuscous colour: head, when seen under a high power, finely 
punctate towards the base: thorax transverse, considerably constricted 
towards the apex, the sides being in outline rectilinear, the surface 
along the line of the base is considerably depressed, which gives to the 
disk (when viewed laterally) a distinctly globular form; this lateral 
depression of the base is even more apparent when viewed in front; 
the surface is coarsely and sparingly punctate throughout: the 
elytra, broad, somewhat parallel, when viewed from above the line of 
the shoulder, form a distinct angle with that of the thorax (the thorax 
at its base appearing somewhat constricted) ; ten strize, consisting of 
small and evenly arranged punctures, are faintly coloured with fuscous, 
the lateral striz being in punctation and colouring more irregular: 
legs and antenne rufo-fuscous. 


This and the following species present a peculiarity of form in the 
striking basal depression of the thorax. The species before us differs 


402 Rey. H. Clark on the Dytiscidee 


from H. gibbus in its almost concolorous elytra, in the punctation 

of the thorax, and in its larger size. 

A single example is in the cabinet of Mr. Bakewell, received by 
him from Adelaide. 
4, H. gibbus, n. sp. 

H. latus, ad medium subparallelus, punctato-striatus, fuscus aut fusco 
umbratus aut flavus; thorace transverse ad basin fortiter depresso et 
punctato ; elytris ad humeros latis et rotundatis, punctato-striatis, striis 
vel tenuiter vel late fuscatis ; pedibus antennisque flavis. 

Long. corp. 14 lin., lat. 4 lin. 

Broad, robust, subparallel, in colour varying from pale flavous to 
fuscous: head elongate in front, at the base obscurely punctate : thorax 
transverse, the sides being rectilinear, and considerably constricted in 
front ; the surface at the base is broadly and deeply marked by a trans- 
verse depression, which, when viewed laterally, gives prominence to the 
anterior disk; the surface is sparingly punctate, more distinctly near 
the line of the base; this punctation varies in different examples, as 
does also the coloration, which sometimes is pale flavous, sometimes 
clouded with fulvous, and sometimes dark fuscous: elytra robust, the 
shoulders being broader than, and forming a distinct angle with, the 
sides of the thorax ; ten strize are formed by fuscous lines, in the midst 
of these lines are series of regular punctures; these lines of fuscous 
colour vary in breadth, in some examples being hardly broader than 
the punctures, in others obfuscating almost the whole surface, thus 
causing the colouring of the elytra to vary in different examples, some- 
times being flavous with narrow fuscous lines, and sometimes entirely 
fuscous: legs and antenne flavous. 


The remarkable thoracic depression in this species separates it 
from all other species of the genus with which I am acquainted, 
except the preceding: from H. fuscatus the species may be distin- 
guished by its smaller size, as well as by the Beas depth and 
breadth of the punctures of the elytra. 

This variable species is found in the neighbourhood of Moreton 
Bay, In the cabinets of the British Museum, Mr. Bakewell, and the 
Rev. H. Clark. 


Tribe II. Prnosrip”. 


Genus Prtosrus, Schonherr. 


1. P. Australasie, n. sp. 


P. ovatus, tenuiter et crebre punctatus, flavo-ferrugineus, infra niger, 
capite nigro; thorace lato ; elytris latis, confertim subfusco punctatis ; 
pedibus antennisque flavis. 

Long. corp. 5 lin., lat. 23 lin. 


and Gyrinidee of Australasia, 403 


Ovate, broad, covered throughout with small closely arranged punc- 
tures, much more minute than in the European species P. Hermanni, of 
a flavous or rufo-flayous colour: head very finely punctate, black: thorax 
broadly transverse, larger than and not so constricted in front as P. 
Hermanni; the surface is subdepressed at the base: elytra broad, finely 
punctate throughout; under a high power, traces may be seen of three 
stria-like lines of paler flavous colour: abdomen and underside black : 
legs and antenne flavous. 


P. Australasie is somewhat larger than the common European 
representative of this genus; the thorax is broader, the punctures 
more minute, and the colour uniformly and much paler: the species 
apparently is not uncommon in the neighbourhood of Adelaide. In 
the collections of the British Museum, of Mr. Bakewell, Mr. Water- 
house, and the Rey. H. Clark. 


2. P. mger, 0. sp. 
P. niger, statura minore, elytris confertim punctatis, antennis pedibusque 
flavis. 
Long. corp. 4 lin., lat. 2 lin. 

Oval, broad, considerably smaller than P. Australasie; the surface 
throughout is covered with thickly disposed punctures, the colour 
black: head somewhat more sparingly punctate and glabrous: thorax 
broadly transverse, the base being transversely subdepressed : elytra 
broad, somewhat flattened in form ; the surface (as that of the thorax) 
is thickly punctate throughout, more closely and coarsely than in P. 


Australasie: abdomen and underside black: legs and antenne rufo- 
flayous. 


From the district of Moreton Bay. In the cabinet of Mr. Bakewell. 


Tribe III. Hyproporipz. 
Genus 1. Hypuynprvs, Il. 


1. H. humeralis, n. sp. 


H., ovatus, brevis, crassus, subpubescens, punctatus, niger; capite flavo- 
rufo, ad basin nigro maculato; thorace nigro, ad latera flavo; elytris 
nigris, ad humeros usque ad suturam et ad latera plus minus flavis, 
apice fusco; pedibus antennisque rufo-testaceis. 

Long. corp. 4 lin., lat. 17 lin. 

Broad, subglobular, somewhat depressed, subpubescent, punctate, 
black: head broad, with two obliquely transverse depressions, one on 
either side ; at the inner margin of the eyes the surface is finely and 
thickly punctate, more distinctly near the base ; in colour flavo-rufous, 
with two basal triangular fuscous markings: thorax broad, much con- 
stricted towards the front, the anterior margin is slightly excavated, 
the surface thickly and somewhat coarsely punctate ; in colour black, 


404 Rev. H. Clark on the Dytiscidee 


the margins being more or less broadly flavous: elytra broad, subglo- 
bular ; the surface is finely pubescent, thickly and deeply punctate ; in 
colour black or fuscous black; at the shoulders transversely and also 
along the line of margin are distributed several rufo-flavous markings 
more or less broad and distinct in different examples; at the shoulders 
the marking is broad, does not reach the suture, and extends somewhat 
beyond the humeral angle for a short distance down the side; along 
the lateral margin are other markings, sometimes almost continuous, 
sometimes consisting of two isolated spots (one medial and the other 
near the apex) ; the apex itself is in all cases flavous: abdomen and 
underside thickly punctate, rufo-testaceous, the apex of the abdomen 
being fuscous: legs and antenne rufo-testaceous, 


H. humeralis is abundantly distinct from all its congeners with 
which I am acquainted: its large size separates it from other 
Australian species; from H. Senegalensis and Madagascar representa- 
tives it may readily be distinguished. 

From the district of Victoria ; it has frequently been taken in the 
neighbourhood of Melbourne, where it is evidently a common species. 
In the cabinets of the British Museum, Mr. Bakewell, and the Rev. 
H. Clark. 


2. H. Blanchard, n. sp.

basin fusco ; thorace ad latera rotundato, antice constricto, ad basin late 
fusco aut fusco bimaculato; elytris obsolete unistriatis, sutura, maculis 
duabus ineequalibus tertiaque transversa juxta suturam nigris; pedibus 
rufo-fuscis ; antennis pallide rufis. 

Long. corp. 23 lin., lat. 14 lin. 

Broadiy ovate, short, punctate throughout, rufo-ferruginous: head 
large, finely and thickly punctate, rufo-ferruginous, the base being 
somewhat suffused with fuscous: thorax transverse, the anterior 
margin emarginate, the sides much constricted in front, and rounded 
in form ; the surface is thickly punctate ; in colour rufo-ferruginous, the 
base being broadly fuscous (occasionally the fuscous marking at the 
base consists only of two large suffused fuscous spots, one on either side 
of the middle): elytra broad, thickly and coarsely punctate through- 
out ; when viewed obliquely, an obsolete stria may be detected on either 
side at some distance from the suture ; in colour rufo-ferruginous, with 
the suture and also two medial longitudinal markings and a third near 
the apex (irregular and broad) being black ; these markings vary con- 
siderably in size: the wnderside is thickly punctate and fuscous: abdo- 
men rufo-fuscous: legs rufo-fuscous, the tarsi being frequently nigro- 
fuscous: antenne pale fuscous. 


The only species before me with which H. Blanchardii may be 
confounded are H. Caledonie: and H. australis: it is larger and rela- 


and Gyrinidee of Australasia. 405 


tively much broader than the former ; it is larger but more elongate 
proportionally than the latter: the coloration also separates it from 
either species. 

The two examples of H. Blanchardii that I know of were received 
by Mr. Bakewell from Victoria ; one, through this gentleman’s kind- 
ness, is pow in my collection, 


3. H. Johnsonii, nu. sp. 


H. ovatus, brevis, punctatus, testaceus ; thorace ad medium nigro-fusco, ad 
latera testaceo ; elytris quatuor aut quinque lineis inzequalibus fuscis a 
medio ad apicem, pedibus antennisque flavis, 

Long. corp. 2 lin., lat. 1 lin. 

Broadly ovate, somewhat depressed, thickly punctate, of a testaceous 
or flavo-testaceous colour: head with two oblique medial foveze, in 
colour testaceous: thorax broad, transverse, in colour dark fuscous, 
the margins being testaceous: elytra broad, thickly and finely punc- 
tate ; near the shoulders are traces of pubescence ; in colour pale flayous, 
with four or five longitudinal lines of fuscous extending from the 
middle to the apex ; these lines are frequently interrupted and irregu- 
larly suffused: abdomen and underside thickly punctate, rufo-fuscous : 
legs and antenne flavous. 


Separated from other species at once by the pale-testaceous colour 
of its elytra and black thorax, as well as by its smaller size. From 
the district of Victoria. 


4. H. australis, n. sp. 


H. ovatus, latus, brevis, dense et minute punctatus, rufo-testaceus, thorace 
ad basin aliquando subobfuscato; elytris obsolete unistriatis, apicem 
versus obfuscatis. 

Long. corp. 2 lin., lat. 1} lin. 

Ovate, short, broad, finely punctate throughout, of a rufo-testaceous 
colour: head very finely and obsoletely punctate: at the base of the 
thorax are, in the two examples before me, traces of fuscous marking : 
elytra broad, thickly punctate throughout; on either side of the suture 
is an obsolete stria, more distinct towards the base, but vanishing as it 
approaches the apex: irregularly shaped and indistinct fuscous markings 
are apparent on either elytron near the apex: /egs and antenne pale 
rufous. 


H. australis closely resembles H. Blanchardii, from which it is 
indeed only to be separated at first sight by its distinctly smaller 
size; a little examination will, however, show that the thorax is 
relatively somewhat narrower, and the markings on the thorax and 
elytra much less pronounced and well defined. From H. Caledonie 


406 Rey. H. Clark on the Dytiscidee 


this species differs by its greater breadth and less clongate form, as 
well as by the absence of markings on the elytra. 

I haye seen but two examples of this species, one from “ Australia,” 
in the cabinet of the British Museum, and a second in my own collec-

5. H. Caledonia, n. sp. 


H, ovatus, convexus, punctatus, rufus, capite rufo-flavo; thorace rufo, ad 
basin transverse fusco ; elytris maculis transversis irregularibus, hae ad 
medium, hac apicem juxta, nigris ; pedibus antennisque rufo-fuscis. 

Long. corp. 2 lin., lat. 14 lin. 

Ovate, convex, thickly punctate throughout, of a rufous colour: head 
broad, rufo-flavous, the base being narrowly fuscous: thorax broad, 
very thickly punctate, in colour rufous, the basal margin being broadly 
fuscous: elytra broad, punctate, rufo-fuscous, with two irregularly 
formed markings, the one medial, the other near the apex ; but the two 
on either elytron are for the most part, apparently, not always united 
together, but broadly separated at the suture from those on the other 
elytron; the form of these maculations varies in different examples ; in 
one example they take the form of broad, almost unbroken, transverse 
bands, in others of smaller isolated spots: legs and antenne rufo-fuscous. 


H. Caledonie is narrower somewhat, and more elongate, than other 
species known to me of this continent. 

Two examples of this species are in the British Museum, from New 
Caledonia. I have received the species from Mr. Cumming, from the 
same locality.

Long. corp. 3 lin., lat. 13 lin. 

Ovate, broad, robust, punctate, rufo-ferruginous: head with two 
minute depressions near the anterior margin; surface almost imper- 
ceptibly punctate: thorax transverse, the anterior margin emarginate, 
the sides constricted in front so as to form a continuous line with those 
of the elytra and head; the surface is thickly punctate, near the an- 
terior margin is a row of minute punctures ; in colour rufo-ferruginous, 
the base being more or less broadly marked with fuscous: elytra 
robust, thickly punctate, and at the sides pubescent; at some distance 
from the suture on either side is an obsolete stria, which vanishes near 


and Gyrinide of Australasia. 407 


the apex ; the colour is ferruginous, with very irregularly formed dark- 
fuscous markings, so irregular that, of the large series before me, hardly 
two examples entirely agree with each other; the ordinary typical 
pattern would seem to be two large medial irregular markings of black, 
occupying nearly the whole breadth of the elytra, and a transverse 
fascia below them, close to the apex; in some examples these two 
medial markings become a transverse band hardly interrupted at the 
suture, in others they are (more or less broadly) connected with the 
apical fascia; in other examples the whole posterior part of the elytra 
is (with the exception of the extreme apex) fuscous black, while 
(that no form of marking might be absent from the species) one ex- 
ample has, from the apex to the base, longitudinal instead of transverse 
markings ; in most instances the anterior surface (with the exception 
of the suture) and the apex are rufo-ferruginous : abdomen and under- 
side thickly punctate, in colour rufo-ferruginous: /egs and antenne 
rufous.

Australia. Taken near Adelaide and at Melbourne. In the col-

Var. A. Elytris omnino fuscis aut rufo-fuscis. 

Long. corp. 23-3 lin., lat. 13-13 lin. 

Oyate, broad, impubescent, thickly punctate, or rufo-fuscous: head 
large, at the inner and lower margin of the eyes is an obsolete circular 
depression, the surface is very sparingly punctate and rufous: thorax 
broadly transverse, the lateral margins are constricted in front, the 
anterior margin somewhat excavated, the surface is thickly punctate 
(more distinctly towards the base), in colour rufous, the posterior margin 
(and also more narrowly the anterior) being fuscous: elytra ovate, 
somewhat narrowed near the shoulders, thickly punctate throughout, 
less distinctly so near the margins; an obsolete but well-defined lon- 
gitudinal stria may be discerned (when viewed obliquely) at some 
distance from the suture; the surface is sparingly pubescent towards 
the sides and base; along the line of the margin is abroad suffused 
rufous marking, extending longitudinally in some examples nearly to 
the apex; near the suture is another longitudinal flavous marking, 
which in most instances does not extend from the anterior margin be- 
yond the middle; between these two a third marking may occasionally 
be traced, narrower and less distinctly defined: abdomen and under- 
side fuscous, the apex being rufous: J/egs and antenne rufo-testaceous. 


408 Rey. H. Clark on the Dytiscidee 


Var. A with the longitudinal markings on the elytra entirely oblite- 
rated, at the shoulders and on the apex alone being found any trace 
of flavo-testaceous. 


H. hamatus at first sight abundantly differs from H. Howittii : the 
broad transverse markings of the latter contrast evidently with the 
longitudinal bands of the former; there are, however, examples 
before me which show that these differences of colour must not be 
regarded as constant. I think that H. hamatus will always be found 
to be perceptibly broader in form, not quite so parallel, and that the 
punctures on the elytra are more distinct and not so closely arranged. 
The two species may be separated from H. Gardnerii by the presence 
of a medial obsolete stria on the elytra, which in the latter species 
is entirely wanting. |

Long. corp. 23 lin., lat. 14 lin. 

Ovate, broad, impubescent, punctate, rufo-fuscous: head large ; near 
the lower and inner margin of the eyes is an obsolete circular depres- 
sion; the surface is impunctate and rufo-flavous, the margins of the 
eyes being fuscous: thorax transverse, the lateral margins gradually 
constricted in front; the surface is thickly punctate, more especially 
near the anterior and posterior margins ; in colour rufo-flavous, the base 
and front being fuscous: elytra ovate, thickly punctate throughout, 
in colour dark fuscous, slightly suffused towards the shoulders with 
flavo-fuscous: abdomen and underside rufo-fuscous: legs and antenne 
flavous or rufo-flavous. 


H. Gardnerii at first sight closely resembles var. A of 1. hamatus ; 
it is, however, decidedly a shorter insect, and the elytra are unmarked, 
as in that species, by any medial stria.

the surface is more distinctly punctate, in colour flavo-rufous, the 
medial posterior disk being black; this medial marking varies in extent 
in different examples, and sometimes contains within itself a basal 
circular flavous patch: elytra very finely and thickly punctate, in 
colour black; from the humeral angle proceeds an irregular flavous 
marking obliquely towards the suture, behind which also is another 
irregular transverse flavous marking; the margin is also more or less 
distinctly flavous; in some examples these markings are severally 
absent, and in some few examples they are all entirely absent, the 
elytra being wholly black: /egs and antenne rufo-flayous.

ANGULUM ORTUSUM SPE FORMANS, 


11. H. collaris, Hope (Proc. Ent. Soc. Lond. 1841, p. 48). 


I do not know this species, which is not in the British Museum 
or any London collection: according to Mr. Hope’s brief diagnosis it 
is piceous in colour throughout, and very finely punctate: in length 
it is 12, in breadth $ line. 

In the Catalogue of Hydrocantharide of the British Museum 
(1847), the name under which this species was described by Mr. . 
Hope is sunk as a synonym, and in its stead is proposed the specific 
name of ‘ thoracicus”: this alteration was proposed probably from 
the fact that there was already a Hygrotus collaris (D. collaris of 
Panzer), and that Hygrotus had been merged as a subdivision of the 
genus Hydroporus. But D. collaris of Panz. is nothing more than H. 
reticulatus of Fab. and other writers ; it is itself merely a synonym’ 
(see Brit. Mus. Cat. p. 31); and thus the name is at the service of any 
subsequent writer who may select it, wherewith to designate any 
other species of the genus. This accidental oversight is the more 
unfortunate because since the date of this catalogue Boheman has 
described an African Hydroporus (Ins. Caffr. i. 1848) under this 
same name of collaris, which must now (by reason of the restoration 
of Hope’s original name to this Australian species) be changed for 
some other name. 

The species was found near Port Essington. 

Professor Westwood has been so good as to examine for me the 
original typical example of this species, which is in the Oxford Uni- 
versity Museum: by his description of it, as well as by a drawing 
which he has very kindly made of the insect, it is apparent that H. 
collaris must be referred to this subsection. Mr. Westwood notices 
four abbreviated strize-like lines on the elytra, very faintly impressed, 
extending from the base a little beyond the middle. No notice of 
these stria is found in Mr. Hope’s concise description.

and Gyrinide of Australasia. 413 


Ovate, broad, of greatest breadth behind the middle, subattenuated 
towards the apex ; very thickly punctate, of a reddish dull black colour, 
with rufous maculations: head short, broad; near the inner margins of 
the eyes are two shallow depressions : thorax broad, subparallel, the 
anterior angles largely rounded ; the surface in front of the middle is 
laterally subdepressed ; the sides are broadly marginate, the margina- 
tions being defined by a sharp deeply-cut fovea extending from the 
front to the line of the base ; at the basal line are three suffused circular 
markings of fusco-rufous, one on either side, and a third medial: elytra 
broad, with four lateral subcircular fusco-rufous markings, three lateral 
at the emargination, and a fourth opposite the one nearest the base : 
legs and antenne rufo-fuscous. 


Somewhat smaller than H. gravidus, and distinguishable also from 
it by its colour, its maculations, and its thoracic margination. 

Two examples are in the collection of the British eae labelled 
“New Holland.” 


13. H. gravidus, nu. sp. 
H. ovatus, latus, subdepressus, crebre punctatus, ater. 
Long. corp. 14 lin., lat. 4 lin. 

Broad, depressed, the surface is very thickly and coarsely punctured 
throughout, in colour black: head broad, punctate ; the surface is un- 
marked by any fovea or depression : thorax broad, the anterior angles 
rounded, the sides broadly marginate ; in colour black, the marginations 
being obscurely tinged with rufous, more distinctly near the basal 
angles: elytra unmarked by any depression ; longitudinal line or stria 
pitchy black; near the apex and also medially (at the extreme edge of 
the margination) is an obscure rufous marking: antenne fuscous, the 
basal joints being rufo-fuscous : degs fuscous. 


This species is closely allied to H. undecim-maculatus ; but, after 
careful comparison, I feel convinced that it is distinct. It is a trifle 
larger in size; the colour is pitchy black, not rufo- pitchy black ; the 
head has no fovew, there are no traces of any maculations, except such 
as have no affinity with this latter species ; and, especially, the hollow- 
ing-out of the thoracic margination (when seen obliquely from in front) 
is bevelled off as a shallow depression—not sharply cut, so as to form 
a deep angular fovea. 

I received some years ago a single example of this species from 
Mr. Stevens, from Port Essington.

414 Rev. H. Clark on the Dytiscidee 


Ovate, broad, somewhat depressed, attenuated towards the apex, 
flavous: head short, broad; on either side within the margins of the 
eyes is a narrow depression; the surface is finely punctate: thorax 
broad, rounded in front, the sides marginate, in front and near the base 
transversely subdepressed; the surface is finely punctate, flavous, the 
anterior and posterior margins being narrowly and evenly fuscous 
black: elytra thickly and finely punctate, flavous, with two,.three, or 
four longitudinal markings of fuscous black; in one of the two ex- 
amples before me the colour is rather fuscous black, with two inter- 
rupted and irregular medial bands of flavous. The great dissimilarity of 
pattern between these two examples plainly shows that the species is 
subject to much variety ; it may readily be distinguished from all others 
by its sectional characters, the absence of any thoracic fovea, the angle 
formed by the sides of the elytra and the thorax, and by its smaller 
size. 


I know of but two examples of this pretty and very distinct little 
species, which I have pleasure in dedicating to R. Bakewell, Esgq., 
whose fine collection has formed the basis of my catalogue of the 
species of these genera.

In this section, the first four species, H. Gilbertii, H. penicillatus, H. 
Wollaston, and H, dispar, have the thoracic fovea not so sharply 
defined ; it is rather one of a small basal group of two, three, or more 
longitudinal strie. 


15. H. Gilbertit, n. sp. 


H. oblongo-ovalis, subtiliter punctatus, flavus, nigro lineatus. 
Long. corp. 24-23 lin., lat. 1-1} lin. 

Ovate, broad, depressed, thickly punctate, subpubescent, flavo- or 
rufo-ferruginous: head finely and thickly punctate, in colour flavo- 
testaceous: thorax broad, in front distinctly excavated, the sides some- 
what rounded and constricted towards the front; at the base are two 
short well-defined longitudinal fovez, which extend parallel to and at 
a slight distance from the lateral margins ; the surface is thickly punc- 
tate, in colour rufo-flavous or testaceous ; in the darker examples the 
anterior and posterior margins are suffused with fuscous: elytra broad 
and somewhat rounded at the sides, depressed ; the surface is thickly 
and finely punctate, the punctures being to some extent in many ex- 
amples concealed by very fine pubescence ; obsoletely punctate strie are 
to be discerned, one closely adjoining another at some distance from the 
suture ; in colour varying from rufous to fusco-flavous, with longitudinal 


and Gyrinide of Australasia. 415 


evenly arranged markings of fuscous: these markings vary in different 
examples, in number for the most part three or four (in some instances 
they are separated by narrow well-defined pale stric-like lines, while 
in other instances these stri# are wanting); they extend from a short 
distance from the shoulders to the apex; sometimes these fuscous 
markings are obliquely interrupted, sometimes the whole surface of 
the elytra is overspread with fuscous: abdomen rufo-fuscous: J/egs and 
antenne rufo-ferruginous. 


I confess that it is not without much hesitation and doubt that I 
have thus characterized the species: the examples before me seem to 
vary not only in size and in coloration, and in character of markings, 
but slightly even in form: undoubtedly from the series individuals 
might be selected which would appear to represent two abundantly 
separate species; but inasmuch as no distinguishing characters 
seem to be constant, and intermediate forms are found, I have at 
last determined on characterizing the whole, pro tempore at least, as 
one species.

elytrisque fusco maculatis ; pedibus antennisque rufo-flavis. 

Long. corp. 13-2 lin., lat. 1 lin. 

Ovate, broad, subdepressed, finely punctate, flavo-rufous: head with 
a distinct depression on either side near the inner margin of the eyes, 
the surface is obsoletely punctate, in colour flavo-rufous: thorax suffi- 
ciently broad, the sides rounded in front and distinctly marginate ; at 
the base are two short fovee (sometimes almost imperceptible, except 
under a high power) situated at equal distance between the middle of 
the line of the base and the margins; the surface is finely punctate, 
flavo-rufous, the anterior and posterior margins, and also two subcir- 
cular markings, one on the inner side of each basal fovea, being fuscous ; 
these subcircular markings are in many examples almost continuous : 
elytra broad, subdepressed ; on either side of the suture is an obsolete 
carination (plainly perceptible when the insect is viewed from the 
front) extending from the base to the apex ; the surface is finely punc- 
tate and fuscous, with longitudinal linear markings of flavous ; in some 
examples these markings are continuous and evenly detined, in others 
they are nearly obsolete, in others, again, they are interrupted, especially 
near the suture and margination: abdomen and underside dark fuscous : 
legs and antenne rufous. 


This species is very variable in the markings of the elytra ; but the 


416 Rey. H. Clark on the Dytiscidee 


examples of it cannot be confounded with those of other allied species, 
in which no carinations on the elytra are perceptible.

H. ovatus, sat latus, subdepressus, punctatus, rufo- vel flavo-ferrugineus ; 
elytris fusco lineatis. 
Long. corp. 2 lin., lat. 1 lin. 

Ovate, broad, depressed, thickly punctate, impubescent, rufo- or flavo- 
ferruginous: head obsoletely punctate, rufo-testaceous: thorax broad, 
subparallel, the sides marginate, the anterior angles well rounded ; the 
surface is obsoletely punctate, more distinctly so near the anterior and 
posterior margins ; at the base are two short longitudinal fovee, in some 
examples these fovez are only part of a short series of corrugations: elytra 
broad, somewhat rounded at the sides, thickly punctate, with 6 or 8 
longitudinal lines of fuscous ; in most examples these lines are regular, 
uninterrupted, parallel, and for the most part of the same breadth as the 
spaces between them ; in some examples the lines are interrupted more 
frequently near the suture medially and apically.—The varieties of this 
species may be grouped under two sections, of which the former pre- 
dominate numerically : A. Colour flavous; the fuscous lines on the elytra 
are more sharply defined, and generally uninterrupted ; the apex of the 
elytra is slightly attenuated. B. Colour rufo-flavous ; the fuscous linear 
markings on the elytra are somewhat suffused; in most examples the 
apex of the elytra is less attenuated. 


I name this species after my friend Mr. Vernon Wollaston, who, 
by his researches in Teneriffe and Madeira, has added several very 
interesting species to our lists of the Hydradephaga. 

From the neighbourhood of Melbourne. In the collections of the 
British Museum, Mr. Bakewell, and the Rev. Hamlet Clark. An 
example of this species in the British Museum is from “ Hobart 
Town, Van Diemen’s Land.” 


18. H. dispar, Germ. (Linn. Ent. 1848). 
Long. corp. 2} lin., lat. 1 lin. 

H, dispar is at once separated from H. Wollastonii by its longer 
form, black thorax (the marginations being flavous), interrupted and 
constricted narrow flavous lines on the elytra, and an obsolete tooth 
near the apex of the elytra. 

This specific name has since been adopted by Le Conte to desig- 
nate a North American species found near Lake Superior.

I am indebted to Dr. Schaum for a typical example of this species 
from the cabinet of Germar.

19. H. multimaculatus, n. sp. 


H, ovatus, subparallelus, sat latus, valde punctatus, flavo-ferrugineus, 
elytris nigro maculatis. 
Long. corp. 1 lin., lat. 2 lin. 

Subparallel, thickly and coarsely punctate throughout, impubescent, 
in colour flayo-ferruginous : head finely punctate, rufo-flavous, the basal 
line being fuscous: the sides of the thorax are parallel, the surface 
thickly punctate ; between and connecting the fovez, near the basal 
line, is a well-defined transverse fovea; the surface in colour is flavo- 
ferruginous, the margination and anterior margin being narrowly fus- 
cous, and the basal line more broadly so, with a dark conspicuous cloud 
of fuscous situated medially and extending to the anterior margin ; the 
black basal marking extends on either side only to the lateral fovea: 
elytra subparallel, thickly and coarsely punctate, in colour flavo-fer- 
ruginous, with thickly scattered fuscous markings; these markings are 
sometimes isolated, subcircular in form, and minute ; sometimes, espe- 
cially transversely, post-medially, they are confluent, and give an appear- 
ance of a transverse band; they present also the appearance of a longi- 
tudinal marking near to and parallel to the suture, and it is probable that 
in different examples the degree of these markings may differ: legs and 
antenne flavous. 


H. multimaculatus is closely allied to H. sinuatocollis ; the macula- 
tions on the elytra are more numerous, and the sides of the thorax 
are parallel. It corresponds more closely still to pale examples of 
H. Meadfootii ; itis longer in form, the transverse thoracic fovea is 
much more abrupt and distinct, the punctations of the surface are 
deeper, and the maculations of the elytra are smaller, more nume- 
rous, and less confluent. 

I possess a single example of this species, received some years 
ago from Mr. Stevens: locality ‘‘ South Australia.” 


20. H. Hansardii, n. sp. 


H. oblongo-ovatus, postice attenuatus, crebre punctatus, niger, flavo 
maculatus. 
Long. corp. 13 lin., lat. 3-3 lin. 

Oblong-ovate, parallel, somewhat attenuated at the apex, thickly and 
deeply punctate, black: head with two small punctations between the 
eyes, black, with a medial longitudinal line of dark rufous: thorax 
broad, subparallel, in front the anterior angles rounded ; the surface is 


418 Rey. H. Clark on the Dytiscidee 


thickly punctate throughout, in colour rufo-flavous, the anterior and 
posterior margins being narrowly fuscous black; the posterior marking 
consists sometimes of two submedial spots: elytra subdepressed, thickly 
punctate, of a dull black colour, with the lateral margins and also six 
small longitudinal markings (three on either side of the suture) flavous ; 
the lateral margins, narrowly flavous continuously, are more broadly 
marked by three longitudinal flavous maculz : legs and antenne flavous. 


Of H. Hansardii I have seen only two examples, from the neigh- 
bourhood of Moreton Bay. The small size of the species, with the 
regularity ofits pattern, sufficiently distinguishes it from those species 
the pattern of which it approaches. 


21. H. Darwinii, Bab. (Trans. Ent. Soc. Lond. 1843, p. 13). 


H. oblong-ovate, punctate, ferruginous: thorax testaceous, with two 
medial spots of fuscous: elytra with a minute tooth near the apex, black, 
with four slender and interrupted testaceous lines on each elytron. 

Long. corp. 2 lin., lat. 1 lin. 


The type of this species is in the cabinet of the Entomological 
Society of London. Originally taken by Mr. Darwin at King George’s 
Sound, during the voyage of H.M. Ship Beagle. 


22. H. sinuatocollis, n. sp. 


H. ovatus, sat latus, haud parallelus, crebre punctatus, flavo-ferrugineus ; 
thoracis lateribus marginatis, sinuatis; elytris crebre fusco maculatis. 
Long. corp. 1-1} lin., lat. lin. 

Ovate, somewhat rounded at the sides; subpubescent, thickly and 
coarsely punctate, rufo-fuscous: head finely punctate, rufo-flavous, the 
base and in some examples the margins of the eyes being fuscous: the 
sides of the thorax have a remarkable sinuation, being excavated me- 
dially or post-medially ; between the basal fovez is a well-defined 
transverse channel, as in H. multimaculatus; the surface is fusco-fla- 
vous, the anterior margin, and more broadly the posterior margin, being 
fuscous; this basal marking extends (more or less broadly) medially to 
the anterior margin, but is bounded laterally by the basal foveze: the 
elytra are somewhat rounded in form, thickly punctate; the surface is 
rufo- or flavyo-fuscous, maculated with dark fuscous markings; these 
markings are sparingly distributed, though differing in different ex- 
amples: legs and antenne rufo-flavous. 

Unquestionably specifically distinct from H. multimaculatus, though 
at first sight possibly to be confounded with it; it is more rounded 
in form, the sinuation of the sides of the thorax is very striking and 
unmistakable, and the markings of the elytra (though this is a far 


and Gyrinidee of Australasia. 419 


less important subject of difference) are on the whole less thickly 
grouped together. H. sinwatocollis differs from H. Meadfootii and 
others inter alia by its transverse thoracic fovea. 

So far as I know, this species has been taken only by Mr. Bake- 
well, who has kindly presented examples from his cabinet to the 
British Museum, and has also placed it in my own collection. 


23. H. Mead footii, n. sp. 


H. ovatus, subparallelus, crebre punctatus, niger, vel niger flavo macu- 
latus, 
Long. corp. 1-1} lin., lat. # lin. 

Ovate, more or less rounded in form, subpubescent, thickly punctate, 
fuscous black: head finely punctate, in colour either black, or fuscous 
black with a medial flavous marking, or flavous with a basal margin of 
black, or flavous : thorax with the sides subparallel; near the base is a 
broad shallow transverse depression, more or less definite in different 
examples; in colour as varied as that of the head, either black with 
flayous margins, or flavous with a medial marking of black, or flavous 
entirely: elytra fuscous black, in many examples marked more or less 
broadly with flavous ; these markings for the most part are distributed 
generally in the form of an ante-medial and also post-medial transverse 
band, consisting sometimes of two or three linear longitudinal markings 
on each elytron; sometimes these markings are almost confluent, and 
form a distinct but irregular band: legs and antenne rufo-flavous. 


It is not without much examination that I come to the conclusion 
that the above different patterns of colouring ought to be referred to 
a single species: I am able to detect no constant difference of sculp- 
ture or form which enables us to separate them: the examples with 
the pale thorax are certainly more constant in their pattern and a 
trifle broader in form, and may possibly, when we know more of this 
group, require to be separated from the others. 

The species has been received plentifully by Mr. Bakewell from 
Melbourne. In the collections of the British Museum, R. Bakewell, 
Esq., and the Rey. Hamlet Clark.

elytra very obsoletely pubescent, in colour flavo-fuscous, clouded irre- 
gularly with a darker shade of fuscous; these markings are for the 
most part post-medial and broadly transverse, in some examples they 
are almost obsolete, in others represented merely by an apical marking : 
legs and antenne flavous. 


The size of this species alone separates it from allied species of 
this section. 

A very common species in §. Australia; received from the district 
of Moreton Bay by Mr. Bakewell. In the cabinets of the British 
Museum, Mr. Bakewell, and the Rev. Hamlet Clark. 


25. H. Shuckardii, n. sp. 


H. ovatus, planus, subtiliter punctatus, rufo-flavus, fusco adumbratus. 
Long. corp. 1 lin., lat. 3 lin. 

Ovate, sparingly and finely punctate throughout, ofa rufo-flavous colour: 
head impunctate, near the margin of the base is a very fine transverse 
thread-like line; flavous or rufo-flavous in colour, the base being more 

. or less broadly fuscous : thorax sparingly punctate, more distinctly near 
the base; the lateral foveze are not parallel with the margins, but tend 
inwards towards the middle; the colour is flavo-rufous, the base and 
middle being more or less broadly fuscous: elytra sparingly punctate, 
of a rufo-flavous or flavous colour; in some examples markings of fus- 
cous obscurely appear, ranged longitudinally; the surface is in all ex- 
amples somewhat mottled: /egs and antenne flavous. 


I name this species after Mr. Shuckard, in accordance with the 
MS. name in Mr. Bakewell’s cabinet. A common insect, apparently, 
near Moreton Bay. In the cabinets of the British Museum, Mr. 
Bakewell, Mr. Waterhouse, and the Rey. Hamlet Clark. 


26. H. amabilis, n. sp. 


H., ovatus, sat latus, subparallelus, punctatus, fuscus vel rufo-fuscus. 
Long. corp. 14-1} lin., lat. 3-4 lin. 

Ovate, broad, impubescent, distinctly punctate, rufo-fuscous: head 
finely punctate, flavous or rufous, or sometimes fuscous: the sides of 
the thorax are somewhat compressed anteriorly, the surface at the base 
is distinctly punctate ; in colour flavous, the base being fuscous: elytra 
subparallel, thickly punctate, rufo-fuscous: legs flavous: antenne rufo- 
flavous. 


A somewhat variable species both in size and colour, and slightly 
in form: the examples with the flavous head are a trifle larger and 
more parallel, and elongated at the apex. I am unable to detect

any constant difference which would constitute them a separate 
species, 

A common insect in the neighbourhood of Moreton Bay. In the 
collections of the British Museum, Mr. Bakewell, and the Rev. Hamlet 
Clark. 

27. H. gemellus, n. sp. 
H., subparallelus, confertim punctulatus, flayo-rufus. 
Long. corp. 1} lin., lat. 2 lin. 

More parallel, more elongate, and narrower than H. amabilis; more 
thickly punctate on the elytra; of a flavo-rufous rather than rufo- 
fuscous colour: head pale rufous, impunctate: thorax flavous, the base 
being fusco-flavous and perceptibly punctate: elytra parallel, finely 
punctate, in colour rufo-flayous: /egs and antenne flavous. 


I think, quite distinct specifically from H. amabils ; it is more 
parallel, narrower in proportion, and more minutely and closely 
punctate.

H. ovalis, punctatus, thorace flavo, elytris rufo-flavis. 
Long. corp. 1 lin., lat. 3 lin. 

A much smaller insect than the preceding, and more oval in form: 
head impunctate, rufo-flavous: thoraz finely punctate at the base, rufo- 
flavous: elytra ovate, and subattenuated at the apex, punctate, in colour 
rufous or rufo-flavous: legs and antenne rufous.

XXXI.—On the Canarian Malacoderms. By T. Vernon 
Wottaston, M.A., F.L.S. 


In the following Paper I propose to give a descriptive enumeration 
of the various Malacoderms which have been detected, up to the 
present date, in the several islands of the Canarian archipelago. And 
I may add, briefly, that I have regarded the Malacodermata as re- 
stricted to the purely flower-infesting members of the Priocerata, 
comprised in the families Telephoride, Malachiide, and Melyride, 
but as excluding the (nevertheless soft-bodied) Drikde and Cy- 


422 Mr. T. V. Wollaston on the Canarian Malacoderms. 


phonide. Whether natural or not, these are the limits which haye 
been assigned to it by those recent writers (Kiesenwetter, Lacordaire, 
and others) who have paid special attention to the representatives 
of this department of the Coleoptera. 

Considering that tie Madeiras, which have been far more perfectly 
explored than the Canaries, have afforded us hitherto but 9 members 
of this great and important Section, it is surprising that so many as 
31* should already have been brought to light in the latter; for 
although the greater amount of surface would naturally lead us to 
anticipate the presence of a larger number of species, still the area 
is not so extensive, compared with that of the former, as to account 
for this wonderful discrepancy. And when I further add that it is 
evident to me that there are many exponents yet to be discovered, 
whilst I have no longer any reason to look for additions from Madeira, 
this disproportionate development of the Malacoderms in the Canary 
Islands becomes still more striking. Nor can it be accounted for by 
the superior development of the Flora; for in both Groups the 
flowering plants are, as a whole, equally insignificant,—that portion 
of their vegetation which is truly indigenous attaining its greatest 
luxuriance, alike in the two archipelagos, amongst the Huphorbiacee, 
the Laurinew, and the Ferns. And we can therefore only accept it 
as a fact, leaving the problem to be solved by those who profess to 
have a more complete insight into the mysteries of nature’s work- 
shop. 

In glancing over the following pages, the great preponderance of 
Attalus (which numbers uo less than 16 species) is the most salient 
fact. And this is the more curious since it is doubtful whether the 
genus is so much as even represented in the Madeiran Group t. Yet 
at the Canaries the Attali are literally everywhere. In the whole 
seven islands, and at nearly all altitudes, we meet with some mem- 
ber, or more, of the genus. In fact wherever flowers are to be found, 
there, throughout the entire year, though more particularly during 
the spring and summer months, are Altali. 


* Only 30 are described in the present Memoir; but a second species of 
Cephalogonia (captured by myself, at Aldea de San Nicholas, in Grand Canary) 
is in the hands of Professor Westwood, who is about to include it in a Paper 
which he is now preparing. 

+ I say “ doubtful” because I have stated below (vide p. 426) that it is not 
absolutely certain that Pecteropus (which has three exponents in Madeira) can 
be kept distinct from Aztalus. At the same time I have expressed my belief that 
it probably may be retained; though zx that case it will be a question yet to be 
decided, whether the P. maderensis and rugosus should not be regarded as Attali, 
and the P. rostratus alone as a Pecteropus. 


Mr. T. V. Wollaston on the Canarian Malacoderms. 423 


I have found it necessary to establish two new genera in this paper 
—namely, Micromimetes and Cephalogonia. The former has most of 
the characters, and the external facies, of Aftalus, except that the 
front tarsi of its male sex are simple (the second joint not being pro- 
duced on its upper side into a tectiform lobe), and also 4- (instead of 
5-) articulate. The latter, on the other hand, is closely related to 
Troglops ; but its anterior male-feet have their second joint con- 
siderably longer (being composed, apparently, of two closely soldered 
together), the third articulation of its antenne is almost as short as 
the minute second one, its abdominal segments are each of them 
broadly membranous along their apical edge, and the head of its 
male sex is much more deeply (indeed very anomalously) scooped 
out, and has the excavated portion furnished in the middle with a 
(more or less evident) tubercle. 

It is somewhat extraordinary that although so many as 31 Malaco- 
derms have already been detected in these islands, not one of them is 
identical with any of the 9 species of the Madeiran archipelago. 
Even the Dasytes illustris, which swarms on almost every rock of the 
latter, has not yet been observed at the Canaries, where its place is 
occupied by a totally different insect, the D. subenescens. It is 
curious, however, that both groups should have exactly three Mely- 
rosomata, which, although perfectly distinct znter se, may be regarded 
as representative of each other respectively. Of genera (apart from 
the two uncharacterized ones already referred to), Malachius, which 
exists in Madeira, has not been discovered hitherto at the Canaries ; 
whilst Dolichosoma and Haplocnemus, which occur at the latter, are 
apparently absent from the former. 

It merely remains to add that in Messrs. Webb and Berthelot’s 
voluminous work on the Natural History of the Canary Islands— 
a publication remarkable for its gigantic proportions but meagre 
and inaccurate contents—only one member of the great Section 
Malacodermata is enumerated, and that one is wrongly named! In- 
deed the whole subject-matter of the present Memoir is there con- 
yeniently disposed of in seven words,—“On remarque quelques 
petits Dasytes et Malachiens.” 

As a slight aid to the eye, in judging of their respective habitats, 
perhaps the following tabulation of the species may not be un- 
acceptable.

The present Malthinus may be regarded as the representative in 
these islands of the European M. flaveolus. It is, however, on the 
average considerably smaller than that insect (descending to a com- 
paratively minute size) ; its limbs and elytra are relatively shorter ; 
its head, although greatly narrowed, is not quite so attenuated 
posteriorly, and has its darker portion more often resolved into 
separate patches; its prothorax has merely the disk ornamented 
with two longitudinal lines (which are sometimes broken up into 
detached spots, and at others completely confluent) ; its elytra have 
even their basal region usually of a rather clearer yellow; and its 
legs are less uniformly pale, the hinder pair (and often the inter- 
mediate ones also) having the apex of their femora black, and 
frequently their tibize and tarsi a good deal infuscated. It is a most 
variable species, both in size and hue; and in some of the smaller 
examples, particularly those from the more barren islands of Lanza- 
rote and Fuerteventura, the femora, especially the posterior ones, 
are clouded or darkened towards their buse (leaving only the apex 
or apical portion paler), and their palpi have the terminal joint more 
decidedly blackened; but, after comparing them with an extensive 
series of specimens collected in six (out of the seven) islands of the 
Group, I have come to the conclusion that they cannot be detached 
from the remainder, their slight differences seeming to be the mere 
result of depauperation, in those individuals in which the stature is 
diminished. Nevertheless I have thought it desirable to treat them 
as a variety. 

There can be no doubt that the M. mutabilis is universal throughout 
the archipelago, in the whole seven islands of which I have myself 
captured it, except Gomera, where our sojourn was so short, and 
moreover so early in the season, that it escaped our observation. In 
Teneriffe, Palma, and Hierro it was found also by Mr. Gray. My 
Fuerteventuran specimens are principally from the Rio Palmas, the 
Canarian ones from El Monte and San Martao, the Teneriffan ones 


426 Mr. T. V. Wollaston on the Canarian Malacoderms. 


from the vicinity of Orotava, S‘* Cruz, Taganana and Yeod el Alto, 
and the Palman ones from the Barranco da Agua. 


2. Malthinus croceicollis, n. sp. 


M. rufo-flavus; capite postice nigro, attenuato; prothorace transverso- 
subquadrato, immaculato; elytris brevibus, nigris, ad apicem solum 
flavis ; antennis nigris, ad basin fusco-testaceis; pedibus nigrescentibus, 
anticis plus minus dilutioribus. 

Long. corp. lin. 13-2. 

Habitat Canariam Grandem, ad flores in regione ‘‘ El Monte” captus. 

In general colour and aspect this species a good deal resembles the 
European sanguinolentus; nevertheless, by the construction of its 
anteriorly widened and posteriorly contracted head, it is a true 
Malthinus, and no Malthodes. Apart from which, it is considerably 
smaller than that insect, its forehead and the extreme apex of its 
elytra are more broadly flavescent, and its limbs are shorter, darker, 
and less robust. Hitherto I have observed it only in Grand Canary, 
where it is not uncommon, during the spring months, on flowers 
throughout the region of El Monte. 


Fam. 2. Malachiide. 


Genus PECTEROPUS. 
Wollaston, Ins. Mad. 247 (1854). 


Whether my genus Pecteropus can be upheld as truly distinct from 
Attalus, I will not undertake to pronounce for certain, seeing that 
the greater number of its structural characters are apparently 
identical with the corresponding ones of the Attali. I am inclined, 
however, to think that, if limited in the Madeiran group to the P. 
rostratus (from Porto Santo and the Desertas), and at the Canaries 
to the P. angustifrons (from Gomera)—in both of which the head 
is narrower and much more oval, with the forehead concave, the 
eyes less prominent, the epistome more produced in front, and the 
neck relatively broader, whilst the maxillary palpi are somewhat 
longer, the entire surface more densely sculptured, and the outline 
more acuminated anteriorly—it may be retained as separate; under 
which circumstances the two genera would bear much the same 
relation to each other as do Malthinus and Malthodes in the Telepho- 
ride. At any rate for the present I prefer this adjustment of the 
species, which seems a sufficiently natural one, to an indiscriminate

Apart from its structural characters (of narrower and more rostrate 
head, &c.) which have already been pointed out, the present insect 
is prima facie remarkable amongst the Attali, to which it necessarily 
bears a general resemblance, by its brightly rufous prothorax and 
dark-cyaneous elytra and head, the latter of which is subopake, and 
most densely and minutely roughened. Its four anterior legs also 
are more or less rufo-testaceous, whilst the two hinder ones are 
nearly black. The second joint of the front feet of its males is so 
very slightly produced into a hood-like lobe on the upper side that 
the latter is scarcely perceptible, except beneath the microscope ; 
but when thus viewed it will be seen, nevertheless, to be more 
strongly pectinated, or spinose, than is usually the case in the true 
Attali. Hitherto it has been observed only in Gomera, where, 
during February 1858, it was taken sparingly by Mr. Gray and 
myself from off flowers on the ridge immediately to the north of San 
Sebastian. 


Genus ATTALvs. 
Erichson, Entomograph. 89 (1840). 


In describing the following Attali I do not think it necessary to 
indicate their sexual distinctions, which are almost exactly the same 
in the whole of them. It will be sufficient to state here that the 
males have their antenne usually just perceptibly longer, their eyes 
a trifle more prominent, their elytra for the most part somewhat less 
ovate (or more parallel at the sides), and the second joint of their 
fore tarsi produced externally into a more or less elongated, concave

The present Attalus and the following one are the universal species 
of Teneriffe, occurring on flowers from the sea-level to an elevation 
of at least 8000 feet. The A. ruficollis may be known by its bright- 
red prothorax, which is usually quite immaculate. The specimens 
from the higher altitudes are generally a little more densely punc- 
tured and eenescent, and have their minute wnder-pile (of short, 
decumbent, subcinereous hairs) more evidently developed ; but they 
merge gradually into the others as we descend into the lower 
districts, and have no character sufficiently constant to warrant the 
suspicion that they are distinct. The “ var. 6” appears to be only 
a small state peculiar to Palma, in which the tibie and tarsi and 
the base of the antenne have a tendency to be testaceous: I captured 
it high up in the Barranco da Agua, as also in the Barranco de Galga, 
and (in a state approaching nearer to the Teneriffan one) at the 
Banda. In Teneriffe it seems to occur universally : my specimens 
are chiefly from the neighbourhoods of 8S Cruz, Orotava and Laguna, 
from Taganana, Souzal, the Agua Garcia, the Agua Mansa, Ycod el 
Alto, and. (from off the blossoms of the Spartiwm nubigena) on the 
two lofty Cumbres—above the Agua Mansa, and adjoining the 
Canadas. Near Sta Cruz it was taken also by Mr. Gray and the 
Bario do Castello de Paiva.

Habitat Teneriffam, vulgaris, in iisdem locis ac preecedens. 

As will be gathered from the diagnosis, the only important cha- 
racter which separates the present Attalus from the preceding one 
is, that its prothorax, instead of being bright red, is (like the rest 
of the surface) black, with merely a small portion at either posterior 
angle (and sometimes the basal margin itself, though very narrowly) 
of a somewhat pellucid yellow. I can detect no other differential 
feature (except that its surface is usually a trifle more «nescent), 
and I might therefore have been inclined perhaps to regard it as a 
variety of the other, had I been able to discover the least trace of a 
passage between the two. But since both of them are equally diffused 
over Teneriffe, independently of elevation, and since in an exten- 
sive series now before me, collected in ten or twelve different (and 
distant) localities, each is equally constant, I have no option but to 
treat them as distinct. Nor indeed can they be sexual forms, seeing 
that I have males and females of both; and I may further add that 
I took the greatest pains whilst in the island to observe whether 
they were ever found in coitu, but could never succeed in so detect- 
ing them, though I frequently captured each species in that situation. 
I have taken it (I believe) in all the Teneriffan localities in which I 
have met with the A. ruficollis, but did not obtain it in Palma. 
Near Orotava it was also found by Mr. Gray; and it has likewise 
been communicated by the Barao do Castello de Paiva. It is the 
species which I described in 1854 (in a foot-note at p. 247 of my 
‘Ins. Mad.’), from a single example which was brought from Tene- 
riffe by the late Rev. W. J. Armitage.

Evidently a most variable insect, but one which may be known 
generally by its ovate (or posteriorly-expanded) outline, by the 
greenish-brassy tinge of its dark elytra and head, by its prothorax 
having usually only the hinder margin and angles pale (though occa- 
sionally a larger portion of its surface), and by its tibie and tarsi 
(and parts of the femora) being diluted-testaceous. It appears to 
be more widely spread over the group than any of the other species. 
I have taken it, though very sparingly, in Fuerteventura ; through- 
out the region of El Monte, as also at Mogan and Teror, in Grand 
Canary (and the ‘var. 6,” which may possibly be distinct, in the 
lofty Pinal of Tarajana, above San Bartolomé, in the same island) ; 
at Taganana, in Teneriffe ; near San Sebastian, of Gomera (though 
only a single example-—the “ var. 3” enunciated above) ; and in the 
Barranco above S Cruz, the Barranco da Agua, and the Banda, of 
Palma; and, since a specimen has been communicated by Dr. Heer, 
stated to have been captured (by M. Hartung) in Lanzarote, it is in 
all probability wniversal throughout the archipelago.

This singular little Attalus may be known at once from the other 
Canarian species here enumerated by its very remarkable sculpture, 
—the head and prothorax (which are much depressed, particularly 
the former) being opake and coarsely and evenly alutaceous (or

minutely granulated) throughout, whilst the elytra are shining, and 
merely roughened in the ordinary manner. Its colour is black, 
except the hinder part of the prothorax (which is dull yellow), and 
the tibie, tarsi, and base of the antenne (which are brownish- 
testaceous). The only two examples which I have seen (a male and 
a female) were captured by myself in Fuerteventura—lI believe in 
the Rio Palmas, early in April of 1859.

The present Attalus, which has been observed hitherto only in 
Gomera, is, like most of the species, very variable in colour ; never- 
theless its subopake and densely and minutely rugulose head (in 
which respect it somewhat resembles the Pecteropus angustifrons), 
combined with the rufo-testaceous hue of its four anterior legs and 
the base of its antenne (the former of which, however, have the 
upper edge of their femora, and occasionally of the tibize also, black), 
will sufficiently distinguish it. Its prothorax has usually the sides 
and base broadly testaceo-rufous ; but sometimes it is entirely dark, 
except towards the hinder angles, whilst at others even the discal 
patch is almost obsolete, when nearly the whole surface is pale. It 
was taken from off flowers by Mr. Gray and myself on the hills above 
San Sebastian of Gomera, at the beginning of February 1858.

The bright cyaneous, or greenish-cyaneous, head and elytra of 
this beautiful Attalus, combined with its rufous prothorax, which 
has generally only a very broad central band darker, and its usually 
black limbs, will serve to characterize it. Its head is less shining 
than the rest of the surface, and is very closely and most minutely 
rugulose; and much the same kind of sculpture exists, though less 
densely, on its pronotum, whilst its elytra are very thickly, though 
delicately, punctulated, and with the additional erect hairs almost 
evanescent at the base but very long towards the apex. It has 
been observed hitherto only on the mountains of Palma. On the 
12th of June, 1858, I captured it rather abundantly from off flowers, 
at a high elevation, immediately below the Cumbre above Buena- 
vista; and during the preceding February it was taken more 
sparingly by Mr. Gray at a lower altitude—I believe, in the district 
of Buenavista itself. Mr. Gray’s examples are the ones which I 
have indicated as the “var. 3,’ in which the prothorax is either 
almost or entirely rufous, and in some of which the anterior legs and 
the base of the intermediate femora are infuscated-testaceous.

This beautiful and comparatively constant Attalus may be imme- 
diately known by its bluish-green and sometimes zenescent surface,— 
the hinder angles and extreme base of the prothorax, together with 
a large apical portion of the elytra (and a narrow lateral strip arising 
out of it and extending to about the middle of the margin) and the 
legs, being of a pale yellow. The legs, however, which are some- 


Mr. T. V. Wollaston on the Canarian Malacoderms. 433 


times infuscated in parts, should perhaps be described as testaceous 
rather than strictly yellow. Its surface is also very densely and 
rather coarsely sculptured, particularly the head and prothorax, 
which are less shining than the elytra; and its antenne are black, 
with the basal joints more or less obscurely rufo-testaceous. That 
it is the species referred in M. Hartung’s list to the Anthocomus 
analis, Panzer, I am enabled to state for certain, having received 
examples thus identified from Dr. Heer, who compiled it. It does 
not possess, however, a single feature, either of size, outline, colour, 
clothing, or sculpture, in common with that insect. In very rare 
cases the large yellow portion at the apex of the elytra is much 
reduced both in dimensions and intensity, when the legs also are 
apt to be almost, or even entirely, dark. It is such specimens as 
these (which however can be connected gradually with the others) 
which I have defined above as the “ var. 3.” 

So far as observed hitherto, the A. chrysanthemi appears to be 
peculiar to Lanzarote and Fuerteventura, where it occurs on the 
flowers of various plants during the winter and spring, though more 
particularly those of the Chrysanthemum ochroleucum of Webb and 
Berthelot. In such situations it was taken abundantly by Mr. Gray 
and myself, between Haria and Magui, in the north of Lanzarote, in 
January 1858; as also subsequently by myself, in the same locality, 
during March of the following year; and, a few weeks later, at Oliva, 
in Fuerteventura.

This Attalus is apparently a good deal allied to the A. chrysanthemi. 
It is, however, less depressed, and more acuminated anteriorly ; its 
surface, instead of being cyaneous-green, is dark-zneous, with the 
entire margins of the prothorax (and not merely the posterior one) 
of a dull fulvous-yellow; its head and pronotum are narrower, much 
more shining, and very much less sculptured (the former being 
almost impunctate, whilst the punctures of the latter are exceedingly 
shallow and ill-defined) ; its elytra (which have, especially towards 
the suture, obscure indications of being longitudinally costate) have 


434 Mr. T. V. Wollaston on the Canarian Malacoderms. 


a much smaller portion at the apex, and also the entire lateral 
margin (instead of only half of it) pale; and its paler parts are 
altogether of a duller or browner tint. The few specimens which 
I have seen (five in number) were captured by myself from off the 
flowers of the Euphorbia piscatoria and balsamifera, on the lofty 
cliffs known as the “ Risco’’ (overlooking the Salinas), in the ex- 
treme north of Lanzarote. They are all of them females; but, 
from their general aspect and their manifest affinity with the last 
species, there can be no doubt that they are correctly referred to the 
present genus.

In general character and outline, the present species somewhat 
resembles the last one. It is however larger, with its head and 
prothorax very highly polished and almost entirely impunctate (a 
few extremely minute and remote points being alone traceable even 
beneath the microscope) ; its elytra are blacker, more coarsely sculp- 
tured, and with the punctures better defined, apparently free from any 
indications of longitudinal coste and rather less pilose (particularly 
in front); and its pale portions are altogether of a much lighter 
yellow,—the prothorax, moreover, having merely a broad central 
band on its fore disk dark. It is hitherto unique,—the single ex- 
ample (a female) from which the above diagnosis has been compiled 
having been captured by myself, in company with the last species 
and the A. chrysanthemi, in the extreme north of Lanzarote.

T have unfortunately but a single example (and that a female one)

from which to compile the diagnosis of the present Attalus ; never- 
theless its characters are so distinct and well-defined that there can 
be no doubt as to the impossibility of referring it to any of the species 
here enumerated. It may be readily known by its rather large size 
and somewhat parallel outline; by its short and depressed elytra 
(which have, at any rate in the female sex, a considerable portion of 
the pygidium uncovered) ; by its large, convex and deeply punctured 
head ; by its exceedingly bright and very lightly punctulated pro- 
thorax; and by its dark hue, the hinder margin of the prothorax 
and the extreme apex of the elytra (which are less enescent than 
the rest of the surface) being alone of a pale whitish yellow. 
Although I have not seen the male, and although the specimen 
before me has certainly a rather different aspect from the species 
amongst which I have placed it, I have nevertheless but little doubt 
that it is a true Attalus. It was taken by myself in the Rio Palmas 
of Fuerteventura, close to the little town of St# Maria Betancuria, at 
the beginning of April 1859.

In its general outline, size, and colour this Attalus bears such a 
curious primd facie resemblance to the Heteromerous <Anthicus 
canariensis, that, until carefully examined, it might literally (although 
in affinity so remote) be mistaken for that insect. And this analogy 
is the more remarkable from the fact of the habits of the two being 
almost identical,—the A. anthicoides receding from the other members 
of the group here enunciated in being found not merely upon flowers, 
but (far oftener), like the Anthic?, beneath dry vegetable refuse lying 
upon the ground. In such situations I have captured it, rather 
abundantly, both in Lanzarote and Fuerteventura, to which islands 
(so far as observed hitherto) it would seem to be peculiar. In fact 
I have frequently taken it in company with the little Anthicus above 
alluded to; and when in motion, at all events, it is next to impos-

sible, from their likeness to each other, to recognize the difference 
between them. It is usually under the rubbish around the base of 
corn-stacks that it is to be found, in which positions it appeared 
pretty general around Haria, in the north of Lanzarote, during 
March of 1859; and it was only at the end of our sojourn there, 
when the sun had become more powerful, that I succeeded in de- 
tecting it upon flowers. My Fuerteventuran specimens are prin- 
cipally from the Rio Palmas. 

The almost testaceous hue of the A. anthicoides—which has merely 
its head, the disk of its prothorax, its femora, the basal joint and 
apical portion of its antenne, and the region of its elytra about the 
base and suture, dark (the latter being only gradually obscured, the 
two tints being shaded-off into each other)—will immediately cha- 
racterize it. Its minute cinereous under-pile is rather denser than 
is the case in any of the preceding species ; and its elytra (which are 
much less shining than the head and prothorax) are of a somewhat 
softer, or less consistent, texture.

Its uneven prothorax, which is distinctly longer than broad, and 
has the central portion at the base slightly raised and divided in the 
middle (so as to form two obscure nodules), and of which the extreme 
margin at the posterior angles is usually (though not always) nar- 
rowly and obscurely pale, combined with the minute and somewhat 
longitudinally disposed subglabrous tubercles of its elytra (the addi- 
tional hairs of which are very long and very erect), will easily 
characterize this Attalus. Its colour is black, with a barely traceable 
metallic tinge (which, however, is a little more apparent on the head 
and prothorax than on the elytra) ; its cinereous under-pile is com- 
paratively coarse and dense; and its limbs are rather thickened, or 
robust. Hitherto I have observed it only around the Puerto Orotava,

The present Attalus I have detected hitherto only in Grand Canary, 
where it is tolerably common, tifughout the region of El Monte, 
particularly towards the summit of the Bandama mountain, during 
the spring. It may be readily known by its black and subopake 
surface (which however has a slightly enescent tinge); by its very 
closely, evenly, and minutely granulose, or alutaceous, head and pro- 
thorax (in which respect it approaches the A. bisculpturatus); by 
its elytra being almost free from additional erect hairs (the few which 
are present being moreover exceedingly short) ; and by the antennz 
of its male sex being rather longer than is the case in the generality 
of the Attali here enumerated. Its prothorax is even, and more 
transverse than that of the last species ; its cinereous under-pile is 
more minute; and its elytra have no indications of the small sub- 
glabrous longitudinally-disposed tubercles which are so evident in 
that insect.

This Attalus appears to be peculiar to Lanzarote and Fuerteventura, 
where it is tolerably common during the spring months on flowers, 
and in the former of which it was also taken by Mr. Gray. It may 
be known by its dark-cyancous hue and but slightly shining (though 
scarcely subopake) surface, which is more or less perceptibly clothed

regular) subalutaceous sculpture of its head and prothorax, on which 
there are only a few excessively small and remote punctures inter- 
mixed; and by its very closely punctulated elytra, which are rather 
flattened on the disk, usually with very faint indications of longi- 
tudinal cost, and beset with erect hairs. My Fuerteventuran 
examples are principally from the Rio Palmas.

The comparatively deeply punctured and almost glabrous surface of 
this Attalus, in conjunction with its metallic hue, which is generally 
greenish brassy, but occasionally almost cyaneous, will sufficiently 
characterize it. It is rather common in Lanzarote, in the north of 
which island it was taken by Mr. Gray and myself, during January 
of 1858, from off the flowers of Euphorbias; in which district I 
again met with it early in March of the following year. I have also 
a single specimen (the “ var. (3”’ indicated above) which I captured 
in Teneriffe, though I cannot now recall the precise locality: it is 
altogether a little more deeply and closely punctured, and has the 
base of its pronotum a trifle raised and uneven; but I do not per- 
ceive anything about it to warrant the suspicion that it is specifically 
distinct.

Mr. T. V. Wollaston on the Canarian Malacoderms. 439 


Whether there be more than a single species included in the above 
diagnosis, I will not undertake to pronounce for certain; neverthe- 
less, since the insect is without doubt a very variable one, both in 
size and sculpture, I am inclined to think, after a careful examina- 
tion of many specimens collected in three of the islands and at dif- 
ferent altitudes, that the “ varieties ’’ which I have indicated are but 
local phases which may be connected sufficiently well with what I 
have regarded as the type. This latter is eminently attached to the 
intermediate and higher elevations of Teneriffe, occurring at the 
Agua Mansa, and on the lofty Cumbre above it, as well as on the 
opposite one adjoining the Canadas. It is almost always of a bright- 
geneous hue, and has its prothorax moderately punctured. The 
examples in the lower regions (at Orotava, Garachico, &c., at the 
latter of which it was captured by the Rev. R. T. Lowe) have their 
prothoracic punctures perhaps a trifle more dense, whilst those from 
the wooded slopes above Taganana have them denser still. These 
last (“ var. 2”) correspond, thus far, with the specimens from the 
island of Palma, which have a thickly, though minutely, punctulated 
prothorax; but I have been perfectly unable to draw a line of 
demarcation between them and those collected from the blossoms of 
the Retama on the Cumbres of Teneriffe. The few which I met 
with in Grand Canary (in the district of El Monte) are blacker; but 
I do not believe that they are specifically distinct. 

The variations, however, of this Attalus do not amount to much 
prima facie, since they are scarcely conspicuous except under a high 
magnifying power. It may be known generally by its eeneous hue, 
and the small size to which it descends; by its rather pubescent and 
more or less finely punctulated surface; and by its usually dark, and 
not very robust (indeed more frequently slender), limbs.

recedes from both Attalus and Pecteropus in having the front feet of 
its males 4-articulate and simple,—the second joint not being in the 
slightest degree produced on its upper side into a process or lobe. 
In minor respects, its head is relatively a little larger and, together 
with the prothorax, somewhat more even and convex; its elytra are 
more parallel at the sides, and almost free from erect additional 
hairs ; and its entire surface is most minutely alutaceous and sub- 
opake. And yet, in spite of the first-mentioned characters, which 
are of primary importance, it so nearly resembles the Attalus chrysan- 
themi in external markings and facies that, before closely examining 
it, I had imagined that it might possibly be a mere depauperated 
state of that species; and it was only when I came to overhaul it 
critically that I discovered it to belong to a totally different group ! 
It certainly, however, affords a strong instance of how easily we are 
apt to be misled by the superficial fact of creatures which are wholly 
distinet in the essential details of their structure being moulded on a 
certain general outward pattern which would seem, for some myste- 
rious reason, to have been assigned par excellence to particular 
countries, or districts. 

The only four genera of the Malachiide hitherto enunciated in 
which the anterior male-feet are tetramerous, are T’roglops, Homeo- 
dipnis, Antidipnis, and Colotes. The last three of these, however, 
are so peculiar in the development of their palpi (which in Anti- 
dipnis and Colotes offer, moreover, the most remarkable sewual 
modifications) that it is unnecessary to point out in what they differ 
from Micromimetes; and we need merely confine ourselves there- 
fore to Troglops. Apart from all secondary characters, the com- 
paratively slender and conical last joint of its maxillary palpi (which 
is regularly acuminated from the base to the apex, instead of being 
more or less thickened and securiform), in conjunction with its 
smaller, convexer, and rounder head (which is alike in both sexes 
and has no frontal depression or excavation), its more even and 
totally different prothorax (which is comparatively wide behind, 
and rounded instead of being suddenly constricted), and its very 
much more abbreviated antenne (each separate joint of which is 
considerably shorter), will at once remove the present genus from 
Troglops. 

I cannot perceive any sexual distinctions in Micromimetes (apart 
from the anterior feet), except that the males (as in the Attal and 
Pecteropi) are a trifle smaller and more parallel, with their eyes a 
little more prominent, and their antenne (although still very short) 
somewhat more elongated. Both sexes are winged.

Although (as lately stated) perfectly distinct from it in real 
structure, yet, regarding the present insect superficially as an Attalus 
(for which it would, at first sight, be taken), I may just add that it 
may be readily known from its apparent allies by its subopake and 
entirely alutaceous surface ; by its dull brassy-black hue (which has 
often a slightly greenish a the hinder margin of the prothorax, 
the extreme apex and lateral edges of the elytra, and the limbs 
(except occasionally a portion of the posterior legs) being pale 
yellow ; by its head and pronotum being convex, whilst the elytra 
are somewhat parallel and depressed ; and by the latter being almost 
entirely free from any indication of additional erect pile. The few 
. specimens which I have seen (only fourteen in number) were cap- 
tured by myself, during April 1858, in the sandy district at Maspa- 
lomas, in the extreme south of Grand Canary.

I would wish distinctly to state that I have placed the present 
insect here merely provisionally, and not with the idea that it is 
truly a second species of Micromimetes ; but having unfortunately 
only a single individual to judge from, and that a female, I am unable 
to conjecture to what group the fore tarsi of its males would tend to 


449 Mr. T. V. Wollaston on the Canarian Malacoderms. 


assign it. From the shape, however, of its posteriorly contracted 
prothorax, which is raised in the centre behind, as well as from its 
general facies and nearly glabrous surface, I feel pretty confident 
that it is not an Attalus; and although in its peculiar prothorax it 
makes a most decided approach to Troglops, it is nevertheless totally 
removed from that genus (apart from all tarsal considerations, which 
may or may not detach it therefrom, as the case may be) by its 
convex, oval (and therefore more posteriorly-widened) head and 
differently placed eyes, by its shorter antenne (with their very 
much more abbreviated joints), and by the terminal articulation of 
its palpi being (as in the three preceding genera) conical and acumi- 
nated. In its convex, thickened head, indeed, and the construction 
of its antenne, it agrees perhaps better with Micromimetes than with 
any other form here enumerated: but I do not believe that it will 
really enter into that group; and it is far more likely that its male 
sex, when discovered, will afford sufficient modifications for the esta- 
blishment of a separate genus. In the meanwhile I would place 
it here provisionally,—its very suggestive prothorax and almost gla- 
brous surface clearly leading us in the direction of Troglops. 

Apart from the features just alluded to, the present insect may be 
known from all the preceding Attah (with which in many respects 
it of course agrees) by its rather large, convex, oval, and regularly 
punctured head ; by its bright-rufous and nearly unsculptured pro- 
thorax; and by its dark-eyaneous elytra, which apparently have no 
minute under-pile, and merely an exceedingly few and remote addi- 
tional erect hairs. My unique example was captured in the region 
of El Monte, in Grand Canary, during the spring of 1858.

For the very excellent figure of the type (and details) of this 
interesting genus I am indebted to Professor Westwood, who has 
kindly both drawn and dissected it with great care. And although 
the insect is so large, I feel bound to add that in my own dissections 
of its very coriaceous mouth I had failed to determine precisely the 
exact nature of its mentum and hgula; so that I avail myself with 
the greater satisfaction of the conclusions arrived at by Professor 
Westwood, whose delineation of the parts in question afford abun- 
dant evidence of his usual accuracy. And I may just state that a 
second representative of the genus, captured by myself in Grand 
Canary, has been brought to light, but is purposely omitted from the 
. present paper, as being well calculated for admission into a memoir 
which Professor Westwood is now preparing on Platyecephalous 
Coleoptera. 

In general facies and structure, Cephalogonia has much in common 
with Troglops, which is its nearest ally. This is particularly apparent 
in the very significant shape of its (rhombiform) head and (posteriorly 
produced yet basally truncated) prothorax, as well as in its almost 
glabrous, highly decorated surface, in the quadriarticulate front feet 
of its male sex, and in the proportions of its palpi. Nevertheless it 
differs from that group in the third joint of its antenne being much

shorter (scarcely longer than the minute one which precedes it), in 
the second articulation of its anterior male tarsi being considerably 
more elongated (and composed, apparently, of two joints closely 
soldered together), in its abdominal segments (or at least the first 
four) being each of them broadly membraneous along their apical 
margins, and in the head of its males being not only more dilated 
and with the eyes larger, but in having also their frontal excavation 
extremely deep and anomalous, being abruptly terminated (and 
trisinuated) either behind or before, and furnished in its centre with 
a curious tubercle, which has somewhat the appearance of having 
been intended to support an ocellus.

The very remarkable colour of this beautiful insect (the head ! 
and prothorax being of a clear cherry-red, whilst the elytra and legs 
are dark cyaneous) will, apart from its structural peculiarities, im- 
mediately distinguish it from everything else here enumerated. Its 
legs are extremely long and slender, and its surface is almost gla- 
brous. I have observed it hitherto only around the Puerto Orotava 
and Realejo, in the north of Teneriffe, where it is not uncommon 
during the spring months, making its appearance about the end of 
February. It is particularly attached to the flowers of the Physalis 
aristata ; and indeed I have never observed it, as yet, on any other 
plant or shrub.

The present Dasytes is closely allied to the common European D, 
flavipes. It differs, however, in being a little larger and more 
pilose, in its prothorax being less abbreviated, or somewhat more 
produced anteriorly, and more transversely constricted behind the 
apex, in its antennee and tarsi being relatively a little longer, and 
in its entire sculpture being more coarse. It is probably universal 
throughout the archipelago, though hitherto I do not happen to have 
observed it in either Gomera or Hierro. But about Haria, in the 
north of Lanzarote, and in the Rio Palmas of Fuerteventura, I have 
taken it commonly ; as also throughout the region of El Monte, in 
Grand Canary; at Orotava, Taganana, the Agua Garcia, the Agua 
Mansa and on the lofty Cumbre above it, as well as on the opposite 
one (adjoining the Canadas) of Teneriffe; and in the Barranco da 
Agua, and the Barranco above St Cruz, in Palma. The Palman 
examples seem to have their legs more uniformly dark than is 
generally the case in those from the other islands, the tibie and 
tarsi (judging from the specimens now before me) being scarcely, if 
indeed at all, diluted in hue. Lanzarotan examples, which were 
collected by M. Hartung, have been communicated by Dr. Heer, 
and one from Teneriffe by the Bardo do Castello de Paiva.

Were it not for the structural dissimilarity between the male 
antenne of the present Dasytes and the last one, I might perhaps 
have regarded them as but states of the same insect ; but since those 
organs in the species now under consideration are longer and slen- 
derer than in the D. subcnescens, their last five joints being con-

siderably more elongated, narrower, and differently shaped, I am 
compelled to lay greater stress upon certain small additional cha- 
racters than I should otherwise have done. Apart, therefore, from 
the antenne of its male sex, the D. dispar may be known from its 
ally by being a trifle slenderer, blacker, and more pilose, by its 
prothorax (particularly in the males) being narrower and less deve- 
loped and in the females a little more deeply and less closely punc- 
tured, by its elytra in the latter sex being more rugose, and by the 
legs of its males (especially the feet) being, like the antenne, longer 
and less robust. I have taken it, sparingly, throughout the district 
of El Monte, in Grand Canary, in company with the last species, 
but have not, hitherto, observed it elsewhere.

Judging from the description and figure, the present insect is 
closely allied to the D. protensum, Gené, from Sardinia, though at 
the same time perfectly distinct from it specifically in most of its 
characters. It would seem to be altogether darker and more deeply 
punctured, with its prothorax narrower behind and unchanneled on 
the disk, and with its entire surface considerably less pilose. The 
sixth joint of its antenne, from the apex, is perceptibly smaller than 
either of those which precede and follow it; but this may very pro- 
bably be the case in its European representative also, though I do 
not see any notice of the fact in the generic formula. It is locally 
far from uncommon, during the spring. months, throughout the 
eastern and central islands of the group. I have taken it around 
Haria, and elsewhere in Lanzarote ; near Oliva, in Fuerteventura ; 
on the calcareous ground at Tafira, in the region of El Monte, in 
Grand Canary ; and on the mountains above S Cruz, as well as

Dr. Heer, who prepared the list. It is, however, unaccompanied by 
insect referred to in his volume under the title of Dasytes filiformis I

any description ; and even if it had been characterized, the name 
could not have been retained, it having been employed by Creutzer 
for the type of the genus—the D. linearis of Fabricius. I have 
therefore much pleasure in dedicating it to M. Hartung.

This large Haplocnemus is remarkable for its brassy-brown surface 

and very deeply sculptured elytra. Its head and prothorax are 

clothed with a fine silken decumbent pile; but its elytra are com- 
paratively glabrous, the hairs (likewise decumbent ones) with which 
they are studded being short and few. Its prothorax is convex, 
with the extreme lateral edges rather pale and minutely crenulated ; 
its legs are testaceous, with the tibize sometimes a little darkened ; 
and the last joint of its maxillary palpi is distinctly securiform. It 
is apparently extremely rare, though widely distributed over Tene- 
riffe, occurring at intermediate and lofty elevations. I have taken 
it in the wood of La Esperanza, at the Agua Garcia, the Agua 

Mansa, and beneath the dead sticks, as well as on the blossoms, of 

the Retamas on the Cumbre adjoining the Canadas—more than 

8000 feet above the sea. And I also observed the mutilated re- 

mains of it (for they were. clearly referable to this species) in Palma.

As will be gathered from the diagnosis, this Haplocnemus differs 
from the preceding one (which at first sight it much resembles) in 
being densely beset all over (in addition to the decumbent under- 
pile of its head and prothorax) with very long, fine, and erect hairs, 
of which there is no indication whatsoever in the H. sculpturatus. 
Its elytra are perhaps a trifle less deeply punctured; and the 
antenne of its male sex are somewhat longer and thicker. Hitherto 
I have observed it only in Hierro, where, during February 1858, I 
captured five specimens of it in the sylvan district of El Golfo, on 
the western side of the island.

The intensely black hue of this Melyrosoma, combined with its 
short, robust, and decumbent pile, its subconical prothorax, and the 
three very elevated costee with which each of its elytra is furnished, 
will sufficiently characterize it. It is alhed to the Madeiran M. 
oceanicum, but is rather larger and of a deeper black, its pubescence 
also is darker and more decumbent, its prothorax is less abbreviated 
and more conical, its elytral ridges are more distinct, its entire 
sculpture is denser and coarser, and its antennze and palpi are a little 
more elongated. Like that insect, it is strictly a mountain species ; 
and the only region in which I have hitherto observed it is the lofty 
Pinal of Tarajana, above San Bartolome, in the centre of Grand 
Canary, where, during April 1858, I took it, not uncommonly, about 
the flowers of the Cytist and Cistt.

Unfortunately I have but a single example of this Melyrosoma, 
and that a female one, to describe from; nevertheless it may be 
known immediately from the MW. costipenne by the very long, erect, 
and fine hairs with which it is densely clothed; by its still coarser 
sculpture ; by its prothorax being shorter and more transverse, and 
with a lightly impressed channel down the disk (instead of merely 
an abbreviated one, or fovea, behind); by its elytral coste being less 
developed ; and by its antenne being perhaps somewhat shorter and 
slenderer. It bears about the same relation to the Madeiran M. 
abdominale as the last species does to the oceanicum of those islands ; 
nevertheless its elongated pubescence is still denser, its prothorax is 
altogether wider (particularly behind), and, together with the head, 
much more deeply and closely sculptured, its elytral punctures are 
larger and more confused or roughened (having no tendency what- 
ever to be disposed in longitudinal rows) ; and although I have not yet 
seen the male sex, I have but little doubt (judging from the specimen 
now before me) that its antennze will be found to be considerably 
shorter. My unique specimen was captured at a lofty elevation on 
the ascent to the Cumbre, above the Agua Mansa, in Teneriffe, 
during May 1859, from off the blossoms of a Cytisus.

clothed, and its slender limbs, will at once separate it from both of 
the preceding species. And it is somewhat remarkable that, whilst 
the M. costipenne and M. hirtum would seem to represent, at the Cana- 
ries, the Madeiran M. oceanicwm and M. abdominale respectively, the 
present one may be regarded as the analogue of the M. Artemisia of 
those islands. And yet, in spite of this general resemblance, it is 
abundantly distinct from it specifically. Thus, it may be known 
by its larger size and more anteriorly acuminated outline, by its 
pubescence being comparatively short and decumbent (instead of 
long, fine, and erect), by its prothorax being much narrower, less 
abbreviated, and more conical, by its entire sculpture being closer 
and less coarse, and by its male antenne being very much shorter 
and with each individual joint considerably less developed. 

The M. flavescens was captured by myself in the mountains of 
Palma, from off the perpendicular rocks which bound the great 
Pinal, above the plains of Los Llanos, in the district of the Banda, 
at the beginning of June 1858. 


XXXII.—Descriptions of new Genera and Species of Phytophaga. 
By J. 8. Baty. 


Fam. Eumolpide. 
Genus Pyropipa. 


Corpus oblongum, valde convexum. Caput perpendiculare, subelongatum ; 
oculis reniformibus ; antennis filiformibus, gracilibus, longitudini cor- 
poris «qualibus, aut femine vix brevioribus; mento apice angulato- 
emarginato ; palporum articulo ultimo ovato, obtuse truncato. Thorax 
Iongitudine latitudini fere eequali, dorso valde convexo, lateribus mar- 
ginatis, breviter rotundatis. Elytra basi thorace multo latiora, apicem 
versus angustata, obovata, basi truncata; punctato-striata, humeris 
prominulis. Pedes modice robusti; femortbus paullo incrassatis, basi 
attenuatis, inermibus ; tibivs posticis quatuor extus ante apicem emar- 
ginatis ; wngutculis basi dentatis. Prosternwm latum, transversum, lateri- 
bus medio paullo productis; antepectoris processu antero-laterali anguste 
cuneiformi, extus ad thoracis angulum exteriorem non extenso. 

Type Pyropida sumptuosa, Baly. 

This lovely insect is very closely allied to Chrysopida, agreeing 
with that genus (and differing from Rhyparida) in possessing a narrow 
wedge-shaped antero-lateral process to the antepectus, differing in 
the shorter, more robust form, in the shorter legs (the thighs being 
also less incrassate and unarmed beneath), and also in the somewhat 
shorter, less exserted head and less prominent eyes.

Pyropida sumptuosa. 

P. oblonga, valde convexa, nitida, cerulea, viridi tincta; elytris late 
purpureis, plaga trigonata communi magna, a basi fere ad apicem ex- 
tensa, aurea; antennis metallico-viridibus.—Long. 4-5 lin. 

Hab, Malacca, Malay Peninsula. 

Oblong, very convex, nitidous, body metallic blue with a green re- 
flexion, more especially on the thorax and legs. Head remotely but 
deeply punctured ; antennz metallic green, covered (the three or four 
basal joints excepted) with a fine adpressed fulvous down. Thorax as 
broad as long in the male, slightly broader in the female, remotely 
punctured. Elytra obovate, truncate at the base, much broader than 
the thorax; humeral callus prominent; disk transversely grooved 
below the basilar space; each elytron with eleven rows of distinct 
but not coarse punctures, the first row short, interspaces plane ; bright 
purple, a large common patch commencing at the base, where it 
occupies the space between the two humeral calli, and extending 

“nearly to the apex of the elytron, gradually narrowing on the suture 
until at last it becomes a mere sutural line, bright golden: 


Fam. Halticide. 


Genus Popontra, Dalman. 


Podontia 14-punctata (Linn.). 


This species appears to possess several well-marked local varieties ; 
two apparently new are described for the first time in the present 
paper. I have had the opportunity of examining several individuals 
of each of the forms, but (beyond that of colour, which appears to be 
permanent and not to vary in the most trifling degree) have not 
been able to detect the slightest difference between them, in sculp- 
ture or otherwise ; the @deagus, which in other species of the genus 
forms a good specific character, does not here show any variation 
whatever. The present is another instance of individuals of the 
same species, brought from distant localities, presenting striking 
and permanent differences in colouring and markings, but agreeing 
in all other and more essential characters, showing us how little we 
ought to depend on colour alone as a specific character.

This variety approaches very closely to P. lutea; Olivier, in his 
very short description of the latter species, does not mention the legs 
as differing in colour from the rest of the body, although in the plate 
they are figured entirely black ; he also gives India, instead of China, 
as the locality of his insect.

Oblong-elongate or oblong, convex, bright rufo-fulvous, nitidous. 
Face transversely depressed between the eyes, impressed on either side 
with a deep groove, which, commencing just above the insertion of the 
antenne, curves obliquely outwards and upwards to the upper edge of 
the eye ; antenne (their base excepted), apex of jaws, anda spot on the 
labrum black; eyes narrowly oblong, also black. Thorax impressed on 
either side with three deep foves, the hinder one smaller than the 
rest, and attached to the basal margin, base with a short longitudinal 
impression on either side and a small round fovea in the middle, the 
latter sometimes obsolete, central portion of disk in front more or less 
distinctly transversely depressed, sometimes also impressed with a 
longitudinal groove; surface sparingly impressed with deep punctures, 
forming on the sides short irregular rows. Scutellum subtrigonate. 
Elytra broader than the thorax, oblong, sides parallel, apex subacutely 
rounded, surface covered with large, irregularly confluent yellow spots ; 
each elytron impressed with eleven rows of deep punctures, the first 
row short, striz near the outer margin sulcate, their interspaces sulcate ; 
towards the apex of the elytron, where the surface is broadly excavated, 
all the interspaces are thickened, subcostate, and covered with indi- 
stinct transverse wrinkles.

Ovate, very convex, nitidous. Face furnished between the eyes 
and just above the insertion of the antennse with two transversely 
placed, shining tubercles; jaws, labrum, and antennze black, the latter 
rather more than half the length of the body, several of the basal 
joints fulvous beneath. Thorax convex, smooth, and indistinctly pune- 
tured on the disk, slightly and singularly excayated on the side just 
within the lateral border, side margins angustate-rotundate. Elytra 
shining black, their basal fourth, together with the inflexed limb, 
fulvous, each elytron impressed with eleven rows of very fine punc- 
tures, the first row short ; these striz, however, are discovered with 
difficulty, owing to the nearly equally well-marked punctation of the 
perfectly plane interspaces; near the outer margin, just below the 
humeral callus, is a shallow smooth fovea. Tibiz unarmed.

within the insertion of the antenne, runs obliquely upwards to the 
upper margin of the eye. Thorax smooth, convex, impressed on either 
side near the lateral margin with a small fovea, surface minutely punc- 
tured; oneither side the disk in front are three longitudinally placed

Oblong-ovate, very convex, nitidous; body beneath deep-purplish 
black; the legs obscure rufo-piceous, the apical half of the hinder 
thighs obscure purple. Body above deep shining purple. Head smooth, 
impunctate ; epistome elevated into a transverse ridge; from its centre 
a strongly raised longitudinal carina runs upwards nearly as far as 
the upper border of the eyes; om either side is a deeply grooved line, 
which, commencing close to the longitudinal ridge, a short way below 
its centre, and just above the insertion of the antenne, runs for a short 
distance perpendicularly upwards, then turns abruptly outwards and is 
carried directly across the face until it reaches the inner margin of the 
eye; here it again forms nearly a right angle with its transverse por- 
tion, and is continued upwards along the inner border of the eye nearly 
to the apex of the latter, where it suddenly terminates; immediately 
above its apex is a deep round puncture; on either side the upper 
portion of the central ridge is a smooth, impunctate, concave space, 
bounded below and on the outer side by the above-mentioned grooved 
line; antennze nearly equal in length to the body, pale fulvous, their 
6th, 7th, 8th, and 11th joints black. Thorax twice as broad as long; 
sides narrowly margined, obliquely narrowed from the base towards the 
apex, anterior portion obliquely truncate, the margin of this latter part 
thickened ; disk indistinctly punctured, the puncturing more distinct at 
the base. Elytra distinctly punctate-striate ; interspaces smooth,

towards their apex) indistinctly sulcate, their interstices obsoletely 
convex, those on the inner disk in front flat, all of them finely but 
remotely punctured.

Acrocrypta must stand close to <Acroleuca, Chevr., which latter 
genus contains many species, nearly all undescribed, from the East ; 
it may be separated by the shorter, more robust, more compressed, 
and much more dilated antenne, and also by the almost globular 
maxillary palpi, with their extremely short and nearly hidden ter- 
minal joint.

XXXITI.—On some Australian Colydiide. 
By Francis P. Pascor, F.L.S., de. 


For a long time all the Australian Colydians have been referable, 
with any certainty, to three genera only—Deretaphrus, Bothrideres, 
and Pycnomerus ; more recently Ulonotus, Merya*, and Bitomat 
have been added in the pages of this Journal. 

Deretaphrus was proposed by Mr. Newman in the ‘ Entomologist,’ 
p. 403, for four Australian insects: subsequently Mr. Janson having 
called the author’s attention to a note of Erichson’s in the ‘ Natur- 
geschichte der Insekten Deutschlands,’ a second notice was given in 
the ‘ Zoologist’ for 1855, App. ecix., preceded, however, by anew and 
elaborate generic description, and accompanied by certain critical re- 
marks from the pen of Mr. Wollaston, who, it is perhaps necessary 
to state, had but a single example of Deretaphrus fossus before him f. 
The result of Mr. Newman’s second notice was to eliminate (but 
apparently with reluctance$) two out of the four original species 
(tllusus and vittatus), which he referred, with the Berlin Professor, to 
Bothrideres. D. puteus, unknown to Erichson, Mr. Newman retained 
in Deretaphrus ; and in this he was followed by M. Lacordaire, who, 


* Ulonotus had been described as an Asida, and Meryx was always supposed 
to be Indian. 

t It will be necessary, however, to form a new genus for the reception of the 
Australian species. 

} In the description, six abdominal segments are mentioned, no doubt a slip 
of the pen, as no Colydian, I believe, has more than five. As Mr. Wollaston 
institutes a comparison between Deretaphrus and Thorictus, I may observe that 
my friend M. de Baran, of Paris, some time ago suggested to me the affinity of 
the latter to another genus of the Colydiide—Aglenus. 

§ Mr. Newman, while apparently deprecating the tendency of Mr. Wollaston’s 
“characters” to limit the genus, is inclined “rather” to “the extension than 
the restriction of generic divisions, on account of the encumbrance to science 
caused by the multiplicity of names.” I may here observe that Deretaphrus 
was, when it was first proposed, referred to a ‘‘natural order—PrinirtEs,” in 
company with Hpiteles contwmax, which belongs to the Clerid@ and is in fact a 
Cylidrus, and Synercticus heteromerus, which Mr. Newman thought bore “a con- 
siderable resemblance to the Clerites, and” that “perhaps a more rigid investi- 
gation of the mouth” might even “establish their [viz. the two specimens de- 
scribed] claim to a station in that order.”” Except by Erichson, in his ‘ Bericht’ 
(1842), I believe this genus has remained unnoticed and unknown. <A few days 
ago, however, at the British Museum, I came upon the identical pair which served 
Mr. Newman for his description, and found it to be the same with Aposyla 
(ante, p. 325), a genus probably allied to Calear, among the Tenebrionide. 
Aposyla must therefore give way to Synercticus. The species, however, are 
different, the one described by me being narrower, with the prothorax broader 
behind, without any traces of elevated lines on the elytra, the punctures finer, &c. 


Mr. F. P. Pascoe on some Australian Colydiide. 461 


however, did not appear to be aware of the article in the ‘ Zoologist ’ : 
but there can be no doubt that this should also be referred to Bothri- 
deres, as I have convinced myself trom an inspection of the type in 
the British Museum; indeed, Mr. Newman’s phrase, “linea ovata 
dorsali profunde impressus,’”’ is sufficient to show that it is not a 
Deretaphrus. In the same number of the ‘ Zoologist,’ Mr. Newman 
describes two new species of this genus—D. Wollastoni and D. 
Erichsoni*, The former of these I have not seen, nor do I know 
where the type specimen is to be found. The species described by 
Germar, in the ‘ Linnea Entomologica,’ i. p. 223, under the name 
of Sigerpes piceus, is quite distinct from any of these, although all 
the authors who have treated of this genus have considered it as 
synonymous with D. fossus; but, inter alia, it is only necessary to 
observe that the “ prothorace subtiliter vage punctato” of Germar 
shows that it must be quite different from the “ prothoraw confertim 
punctus” of Newman. 

The affinity of the two genera, Deretaphrus and Bothrideres, seems 
to me by no means close: the peculiar structure of the mouth of the 
former, the character of the antenne with a club of three subequal, 
transverse joints, the subapproximate posterior coxse with the inter- 
femoral process rounded anteriorly, and the subequal basal segment 
of the abdomen, are all points which contrast strongly with Bo- 
thrideres. 

With regard to Pycenomerus, the extra-European species with 
eleven-jointed antenne having been separated from those with ten, 
Erichson’s P. fuliginosus and the two presently to be described must 
be referred to Penthelispa (ante, p. 111). 

I have nothing to add at present in reference to the genera 
Ulonotus, Meryx, and Bitoma. 

The greater part of the new species described below I owe to the 
kindness of Robert Bakewell, Esq., to whose liberality, as this 
Journal testifies, I have been so often indebted. There are, how- 
ever, some others in his collection which, being unique, I have passed 
over. The Colydiide are a family whose haunts, to be known, require 
those who will patiently persevere in their search for them, and 
hence they rarely occur to collectors who are not also close observers ; 
it is therefore probable that their species will be found to be much 
greater than the number at present in our cabinets would lead us to 
infer. 

In the following descriptions I have avoided, as unnecessary

his Genera des Coléop. ll. p- 37 fy nove,

repetition, noticing those characters which either belong to the 
genus, or which are so slightly modified as scarcely to be appreciated 
even when neighbouring species are contrasted with one another. 
For the generic characters, so far as they relate to Deretaphrus and 
Bothrideres, I must refer to M. Lacordaire’s ‘Genera des Coléoptéres,’ 
ii. pp. 377-78, where they will be found carefully and accurately de- 
tailed. Penthelispa is described in this Journal, p. 111: its species 
are found in all parts of the world, except Europe.

Dull rufous brown; head and prothorax strongly punctured, the 
latter with a sharply impressed, longitudinal canal, scarcely extending 
beyond its basal half, no anterior canal, but a shallow depression 
instead ; elytra seriate-punctate, the interstices, except the two inner, 
raised into strongly marked cost, especially the basal portions of the 
third *, fifth, and seventh, the punctures large, and at regular intervals ;

the finer punctures which are so obvious under a good lens in D. 
fossus and D, viduatus. 


Deretaphrus viduatus. 


D. niger, subnitidus ; prothorace fortiter punctato, interrupte canaliculato; 
elytris interstitiis quinto et septimo costatis ; pedibus piceo-nigris. 
Hab. Adelaide. 

Black, subnitid ; head and prothorax strongly punctured, the latter 
with a deeply impressed, interrupted longitudinal canal, with the 
anterior portion narrow, but well defined; elytra less nitid than the 
prothorax, seriate-punctate, the interstices towards the suture scarcely 
raised, except at the apex and base, the fifth, sixth, and seventh form- 
ing strongly marked costz, especially the fifth and seventh, the punc- 
tures large, round, and at regular intervals; body beneath black, 

_ shining, coarsely punctured ; legs pitchy black. Length 5 lines. 


Darker and less glossy than Deretaphrus fossus, the prothorax 
narrower, the third interstitial line especially not prominent, and 
the punctures between them more regular in form and more equally 
distributed ; in both species the interstices themselves have each a 
fine row of small punctures. 


Deretaphrus Bakewellii. 


D. angustulus, rufo-fuscus, nitidus ; prothorace subtiliter punctato, pro- 
funde interrupte canaliculato, lateribus antice rotundatis ; elytris striato- 
punctatis, interstitiis alternis elevatis. 

Hab. Melbourne, Sydney. 

Narrow, dark reddish brown, glossy; head and prothorax minutely 
punctured, the latter with a deeply impressed, interrupted longitudinal 
line, the anterior portion very short, but deep and well defined; elytra 
seriate-punctate, the third, fifth, and seventh interstices forming elevated, 
costeeform lines ; body beneath brownish pitchy, with shallow, scattered 
punctures; antenne and legs reddish pitchy. Length 5 lines. 


A more slender form than Deretaphrus piceus, with the prothorax 
proportionally more constricted at the base, and more rounded ante- 
riorly, of a decidedly reddish-brown colour, and more glossy. 


Deretaphrus cov, dioides.

narrow ; elytra seriate-punctate, with the alternate interstices raised, 

and the punctures in the strive large and very strongly marked; body 
beneath reddish pitchy, with coarse scattered punctures; legs ferru- 
ginous, shining. Length 23 lines. 

The smallest and slenderest of the Deretaphri, and somewhat cylin- 
drical, or at least its depth very nearly equalling its breadth, although 
above it is slightly depressed, as in the other species. In the diminu- 
tion of the anterior portion of its prothoracic canal it resembles 
Deretaphrus fossus, but, notwithstanding its smaller size, it is much 
more distinct. :

Dark reddish brown, somewhat opake; head with crowded oblong 
punctures; prothorax longer than broad, coarsely punctured, anterior 
angles prominent, a short groove at the base, the disk slightly depressed 
and marked with two small semicircular impressions; elytra strongly 
punctate-striate, with three lateral alternate interstices forming raised 
lines or coste ; body beneath reddish brown, strongly punctured ; legs 
reddish ferruginous. Length 33 lines. 


Narrower than Bothrideres illusus, and more opake ; the prothorax 
more depressed, with two distinct impressions and a punctation 
wholly different. 


Bothrideres teeniatus. 


4. rufo-fuscus, nitidus ; prothorace rude punctato; basi trisulcato, disco 
biimpresso ; elytris rufo-brunneis, sutura fusca. 
Hab. Melbourne. 

Dark-reddish brown, shining ; head closely and coarsely punctured ; 
prothorax coarsely punctured, longer than broad, the anterior angles 
prominent, disk rather depressed, with two deep semicircular impres- 
sions, the space between not punctured in the centre, behind the pos- 
terior impression a broad shallow canal, and on each side of the canal a 
slight groove; elytra reddish brown, shining, the suture dark brown, 
punctate-striate with the alternate interstices raised ; body beneath red- 
dish brown, coarsely punctured; legs reddish brown ; palpi testaceous 
yellow. Length 23 lines. 

Bothrideres vittatus, which resembles this species in the dark- 
coloured suture, is at once distinguished by its prothorax being 
without any impressions, except that the whole disk sinks down, as 
it were, leaving only a slight median elevation at the base. 


Bothrideres musiwus. 


B. fulvo-brunneus, nitidus; prothorace fortiter punctato, disco late de- 
presso, medio vix elevato; elytris fulvo-castaneis. 
Hab. Melbourne. 

Light-yellowish brown, shining ; head thickly punctured ; eyes black; 
prothorax longer than broad, coarsely punctured, anterior angles not 
prominent, the disk with a large, oblong, shallow, somewhat parallelo- 
grammic impression, slightly raised at the base and in the middle, 
where it is smooth and without punctures ; elytra uniform pale yellow- 
ish brown, shining, striate-punctate, three lateral alternate interstices 
costeeform ; body beneath darker brown, and rather sparsely punctured. 
Length 2 lines. 


Smaller and the colour more uniform and paler than in Bothrideres 
vittatus ; the depression on the prothorax larger and less divided by 
the medio-basal ridge. 


466 Mr. F. P. Pascoe on some Australian Colydiide. 


Bothrideres merus. 


B. lutescens, subnitidus; prothorace fortiter punctato, disco late depresso, 
medio yix elevato; elytris luteis. 
Hab, Melbourne. 

Luteous yellow, subnitid; head with crowded, oblong punctures ; 
eyes black; prothorax scarcely longer than broad, strongly punctured, 
anterior angles scarcely produced, the disk with a large, broad, shallow 
depression slightly raised posteriorly, with a smooth ovate point in the 
centre; elytra luteous, rather more glossy than the prothorax, striate- 
punctate, the punctures rather small, the alternate interstices slightly 
raised ; body beneath reddish brown, coarsely punctured; legs and 
antenn luteous brown. Length 13 line. 


From Bothrideres musivus this species may be distinguished by its 
smaller size, paler and less glossy colour, and proportionally shorter 
and less coarsely punctured prothorax: in both the elytra are less 
deeply striated, the interstices near the suture being very obviously 
punctured. 


Bothrideres lobatus. 


B. fulvo-luteus, subnitidus; prothorace longitudinaliter corrugato, basi 
bilobato, disco postice linea semilunari impresso ; elytris sutura mar- 
gineque infuscatis. 

Hab, Sydney. 

Pale brownish yellow, subnitid; head sparingly punctured; pro- 
thorax slightly convex, rather broader than long, finely corrugated 
longitudinally, a very distinct semicircular impression posteriorly, 
between which and the base are two small diverging lobes; elytra 
slightly convex, the suture and lateral margins darker than the disk ; 
body beneath pale brownish yellow, moderately punctured. Length 
13 line. 

The short and corrugated prothorax, with its two raised and 
diverging lobes at the base, render this species easy of recognition. 


Bothrideres servus. 


B. fulvo-brunneus, subnitidus; prothorace longitudinaliter corrugato, 
postice linea subcurvata impresso, basi late sulcato; elytris sutura 
marginibusque infuscatis, 

Hab. Melbourne. 

Light yellowish brown, slightly shining; head and prothorax with 
coarse punctures, more or less confluent in a longitudinal direction, 
giving the intervals a corrugated appearance, the latter nearly equal in 
length and breadth, its anterior angles rather prominent, the posterior 
impressed line only slightly curved, no anterior impression, a broad 
shallow groove at the base ; elytra with the suture and margins darker 
than the disk, striate-punctate, the three lateral alternate interstices 


Mr. F, P. Pascoe on some Australian Colydiide. 467 


costeeform ; body beneath light yellowish brown, rather finely punctured, 
with the anterior margins of the abdominal segments dark brown ; 
eyes black. Length 2 lines. 


The single and very slightly curved impression on the prothorax 
is sufficiently distinctive of this species. 


Bothrideres versutus. 


B, rufo-fuscus, vix nitidus ; prothorace longitudinaliter corrugato, postice 
linea curvata impresso, basi late sulcato ; elytris concoloribus, interstitiis 
alternis punctatis. 

Hab. Melbourne. 

Reddish brown, scarcely shining ; head corrugated, especially in front, 
punctured behind the eyes; prothorax nearly equal in length and 
breadth, slightly contracted at the base, the anterior angles prominent, 
covered with coarse oblong punctures throwing the intervals into small 
longitudinal folds, the impressed line at the base semicircular, having 
a smooth space in front, and a shallow, broad groove behind; elytra 
coarsely striate, the alternate interstices, commencing at the sutural 
one, with a very obvious line of punctures, the three lateral costseform, 
the strize apparently impunctate ; body beneath reddish brown, shining, 
coarsely punctured, the punctures on the abdominal segments gradually 
more crowded as they approach the last. Length 23 lines. 


Perhaps most nearly allied to the last on account of its corrugated 
prothorax, with its single impressed line, which, however, is deeper 
and more decidedly curved ; the colour is also different, and the punc- 
tures on the alternate interstices are less marked. 


Penthelispa secuta. 


P. fusco-picea; prothorace obsolete biimpresso, angulis posticis rotun- 
datis; elytris punctato-striatis, lateribus a basi sensim angustatis. 
Hab, Melbourne. 

Dark pitchy; head and prothorax coarsely and somewhat closely 
punctured, the latter rather longer than broad, very.slightly incurved 
at the sides, and rounded at the posterior angle, the disk with two very 
shallow, almost obsolete, longitudinal impressions; scutellum broadly 
transverse ; elytra coarsely striate-punctate, very gradually receding 
from the base to the apex; body beneath pitchy, with rather distant 
punctures; antennz and legs reddish ferruginous, shining. Length 
2 lines. 


Very like Penthelispa porosa (a Rio insect), but darker, rather 
less depressed, and more strongly punctured, especially on the pro- 
thorax, which has also its posterior angles more rounded.

with irregular shallow depressions, and each of the interstices furnished 
with a row of punctures; body beneath pitchy, coarsely punctured ;

XXXIV.—Descriptions of Species of the Genus Hydroporus, Clairy., 
new to the European or British Catalogues. By the Rev. Hamier 
CiLarK. 


I snoutp be very glad if any British entomologists, into whose 
hands this paper may fall, would allow me to inspect any doubtful 
species of this genus that may come under their observation. I 
have no doubt that several species known on the Continent, as yet 
unknown in Great Britain, may yet be detected in our pools and 
streams: the latter habitat I would especially commend as likely to 
supply interesting or new species ; two of the species described here 
were taken in streams. -Agabus brunneus, one of our rarest British 
water-beetles, has just been taken by Dr. Power and Turner in 
a stream in the New Forest ; Haliplus fluviatilis is taken in streams 
(in the Seine, Rhone, &e.) ; H. opatrinus I have taken on the Con- 
tinent, in streams ; H. ferrugineus, another of our rarest species, was 
taken by Stephens in a stream at Kimpton. In a paper in the 
‘ Zoologist,’ 1855, p. 4846, I pointed out the Continental species that 
we might expect to find in Great Britain; a few of these have since 
been discovered. 

The following paper contains notices of three species of this genus 
apparently hitherto undescribed,—two of them, H. derelictus and 
H. celatus, taken in Great Britain; the third, H. Andalusie, in . 
Spain. 


of the Genus Hydroporus. 469

Aubé, Iconographie, v. 367, pl. 42. fig. 2. 
Sp. ——? Waterhouse, Cat. Brit. Col. 8vo, 1861, p. 107. 

Examples of this species were taken, some years ago, by Mr. 
Waterhouse, probably in the London district: it is a new species to 
the British lists. It is closely allied to H. reticulatus, Fab., with 
which it may often haye been confounded. The thorax is a trifle 
broader, the basal margin of fuscous is more distinct, and the punc- 
tation somewhat more frequent and deeper: in the elytra, the four 
longitudinal markings, which in H. reticulatus are interrupted post- 
medially, and are not continued to the base, are narrower, more 
regular, uninterrupted, and continued to the base parallel with and 
similar to the sutural marking. The punctation of the elytra is 
especially different : in H, reticulatus, under a high power, the surface 
will be seen to be covered with very minute and very thickly distri- 
buted punctures, among which are others deeper, broader, and at 
some distance from each other; in H. quinquelineatus, the punctures 
are uniform and coarse, tolerably evenly arranged. I have received 
the species from Dr. Schaum, Prof. Boheman, and others, from Lap- 
land and Norway. British examples, taken as yet only by Mr. 
Waterhouse, are in the cabinets of Mr. Waterhouse, Dr. Power, and 
Rey. H. Clark. 

H. Andalusie, n. sp. 

H. ovalis vel pene oblongo-ovalis, depressiusculus, haud pubescens, sub- 
tilissime et crebre punctatus, testaceus vel fusco-testaceus: thorace 
ad latera rotundato, ad discum medium subrotundato (marginibus 
leviter depressis), antice et ad basin irregulariter punctato etiamque 
plus minus transverse nigro, maculisque duabus ad medium basalibus 
subcircularibus nigris: elytris griseo-testaceis, striis duabus undique

bus ordine veluti tribus vittis transversis dispositis: pedibus rufis, 
tarsis anterioribus rufo-fuscis: antennis rufis, ad apicem fusco notatis.

Very closely allied to a species (H. Clarkii) discovered in the 
Canaries by Messrs. Gray and Wollaston, and described by the 
latter in ‘Annals and Magazine of Natural History,’ 1862 (June), 
p. 438. After a very careful examination of the two forms both 
by Mr. Wollaston and myself, it has seemed to us that the two 
ought to be recorded as distinct species : a comparison of a series of 
the two shows that H. Clarkii is larger, more oblong, more shining, 
less pubescent ; the spines also at the apex of the elytra are less 


470 Rev. H. Clark on some Species 


distinct in proportion to its size. H. Clarkit is a little more parallel 
and broader towards the shoulders, and the four anterior fect of the 
male are somewhat more dilated than in the species before us. 
Head with two antical depressions, the surface is obsoletely granu- 
lated and finely punctate-rufous: the thoraw is rounded in front, 
the sides being subparallel ; the surface is finely and sparingly punc- 
tate, flavo-rufous, the base and two medial basal subcireular mark- 
ings being fuscous: elytra with two faint strie, one sutural and the 
other submedial; in colour pale testaceous or flavo-testaceous, with 
four or five irregular, interrupted, longitudinal lines of fuscous, 
which vary much, in different examples, in breadth, in length, and 
in degree of continuation ; for the most part, these lines are so trans- 
versely interrupted that they form (in general appearance) three 
irregular transverse bands ; the spines at the apex of the elytra are 
certainly decidedly more developed than in H. Clarkit (in which 
species they are almost obsolete), assimilating in development to 
those of H. assimilis, Payk. 

My friend Mr. Gray and I captured this handsome species at 
Malaga, on May 13 and 29, 1856, in pools formed by mountain 
watercourses, in company with Colymbetes coriaceus, Agabus brun- 
neus, and others. I have also received the species from M. Schau- 
fuss as undescribed, from the South of Spain. 


H, halensis, Fab. 


H. ovalis, subtiliter pubescens, pallide fuscus: capite flavo, ad latera et 
apicem fusco: thorace pubescenti-flavo, undique juxta medium irregu- 
lariter fusco notato: elytris pubescentibus, pallide testaceis, lineis sex

Long. corp. 2 lin., lat. 1 lin. 

Oval; perceptibly broader and less parallel in the sides than H. 
assimilis, Payk., the sides of the thorax also being continued in a more 
direct line with those of the elytra than in this species; the coloration 
is entirely different, being less tinged with rufous, and the longitudinal 
lines on the elytra being narrower: the head is narrower; the two de- 
pressions at the inner margins of the eyes are more distinct ; in colour 
the lateral margins are much more broadly fuscous: the thorax is 
broader than in HZ. assimilis, Payk.; at the anterior margin isa single 
regular row of distinct fuscous punctures (not frequent and unarranged 
minute punctures); the surface is pubescent, thickly and evenly punctate 
throughout. In H. assimilis the surface is rather minutely granulated, 
the granulations being interspersed with more distinct punctures ; the 


of the Genus Hydroporus. 471 


colour of the thorax is flayous, with a tendency to rufo-flayous, the 

Basal line and also two subtriangular markings, one on either side of 

the middle (which are connected with the base, but terminate at some 

distance from the anterior margin) being fuscous: elytra broader, and 
more rounded at the sides, than in H. assimilis, Payk. Six fuscous 
lines, longitudinal, evenly disposed, and regular in continuation and 
colour, extend from the apex to the base ; these lines are much narrower, 
and the interstices broader, than in ZZ. assimilis ; the testaceous colour 
of the interstices between the 1st and 2nd lines (from the suture) is 
interrupted at three points by a narrow fuscous junction of the lines 

(basal, ante-medial, and post-medial), between the 2nd and 3rd at one 

point (medial), between the 3rd and 4th at two points (medial, less 

distinctly, and basal), between the 4th and 5th at no point; the 5th 
and 6th lines take the usual form of broader abbreviated markings (in 

H. assimilis the interstices between the lines are less interrupted) : 

legs rufo-flavous, the anterior and the joints of the posterior tarsi being 

fuscous: antenne flavous, the apical joints being fuscous. 

H. halensis is a trifle longer than H. assimilis, Payk.; the apical 
spines of the elytra are obsolete ; it is not so acute at the apex, and 
(as will have been seen) differs widely in stronger pubescence and 
coloration. The species is also closely allied to, but distinct from, 77. 
Andalusie, described in this paper; it is shorter and rounder in 
form ; and the markings of the elytra are, in all the examples before 
me, constant in their difference of pattern. It is perhaps most nearly 
related to H. fuscitarsis of Aubé, from Sardinia ; this latter species, 
however, is impubescent, the general colour of the elytra is decidedly 
darker by reason of the greater breadth of the fuscous lines, the general 
form is narrower, and a trifle more parallel, than in H. halensis. 

Dr. Schaum has pointed out to me that our Scotch species, found 
only in Mull (‘ Zoologist,’ p. 4859), which has, since his paper in 
the ‘Zoologist’ (p. 1890), stood in our cabinets under the name of 
halensis, Fab., is the true griseostriatus of DeGeer,—the error haying 
arisen from a confusion on the part of the late Mr. Stephens, between 
his cabinet and his ‘Manual’ and ‘ Illustrations,’ and that this species 
is the true halensis of Fabricius. 

This species has been twice taken in England—in Horning: Fen, 
Norfolk, by myself, in May 1855, in a running stream, and also, 
by Dr. Ernest Adams, in a little river (‘the Gipping?”) near 
Haughley, Stowmarket, Suffolk.

Long. corp. 2 lin., lat. 1 lin. 

Nearly allied to H. plunus, Fab., but slightly narrower, more 
parallel, and not so rounded in form: in H. planus the greatest 
breadth is medial, in H. derelictus it is post-medial. The thorax of 
H. planus is covered with minute punctures ; in the species before us 
it is at the margins more coarsely punctured, and medially impunc- 
tate: the basal outline is (by reason of the more distinct definition 
of the medial scutellary angle) somewhat more sinuate ; the colour 
of the head is entirely different: the elytra are pubescent (not 
simply glabrous), of a deep black colour (not fuscous or rufous black), 
and more obviously punctate; in one of the examples before me, 
a 9, the colour is entirely opake, not shining, and the punctation 
of the elytra appears to be somewhat closer: the tarsi are all (in 
every example) distinctly fuscous, and the anterior tarsi of the 3 
appear to be broader and more dilated. 

In colour of head and elytra, and in its fuscous tarsi, it more 
nearly resembles H. erythrocephalus, Linn. ; but this latter species is 
very distinctly more rounded, and a smaller insect. 

I received six examples from a bird-collector in the island of 
Orkney, whom I employed to collect water-beetles for me, in August 
1855. The species probably was then abundant. During an entomo- 
logical tour through the Western Isles of Scotland, last autumn, with 
Mr. John Gray, in which we specially sought to collect Hydrade- 
phaga, we were unable to meet with a single example of this species. 
By the kind aid of M. Javet, M. Aubé of Paris has been good enough 
to examine a specimen which was returned by him “ unknown.” I 
have a note that the species appeared to me to be very closely related 
to H. lapponum, Gyll., of the collection of the Jardin des Plantes ; 
but the opportunities that I have had of examining insects in that 
museum have not been always very favourable ; and H. lapponwin 
of Gyllenhall is, according to examples I have received from M. 
Boheman, narrower, less pubescent, more rufo-fuscous in colour, and 
with the elytra more sparingly punctate. M. Thomson has described 
a species (H, Bohemanni) which probably is very near to this species. 


of the Genus Hydroporus. 473 


Iregret much that I have had at present no means of comparing 


the two together. In the cabinets of Dr. Power, Mr. Waterhouse, 
and the Rey. H. Clark. 


H. celatus, n. sp. 

H. oblongo-ovalis, leviter convexus, punctulatus, nitidulus, niger: capite 
inter oculos bifoveolato, minutissime punctato, nigro, ad basin anguste 
ferrugineo : thorace lateribus obliquis subrotundatis, marginatis, ad 
basin transverse subdepresso et crebre punctato, antice stria transversa 
punctorum una, plerumque haud interrupta, ad medium diseum sparsim 
punctulato vel pene impunctato: elytris ad latera subrotundatis, punc- 
tulatis, striis duabus undique punctorum majorum a basi ad apicem : 
antennis rufis, pedibus omnino rufo-flavis. 

Long. corp. 13 lin., lat. 3 lin. 

I have before me four examples, taken at three different localities, 
of a form of Hydroporus, which are absolutely identical in shape, 
size, and sculpture. The form is unregistered in our British lists, 
and I am unable to assign it to any described species known on the 
Continent. As, in such a very difficult section of the genus as that 
to which this species belongs, any conclusions that are not based upon 
careful comparison of authentic types are at best but inconclusive, 
it is only perhaps provisionally that the species will stand as H. 
celatus. My own belief is, having carefully examined descriptions 
and also examples of most of the species found on the Continent, that 
it will prove to be as yet undescribed ; at all events, it is new to Great 
Britain. In general form it closely resembles H. vittula, Er. It is 
however, a much larger insect, the punctures on the thorax are less 
regularly distributed (the base being deeply punctate, while the 
medial surface is almost impunctate), the striz on the elytra are less 
distinct (and only punctured striz, not slight longitudinal depres- 
sions), while the legs are entirely rufo-flavous, not suffused with 
fuscous. From H. nigrita, Fab.,it may be distinguished, as well by 
its much greater size, as by its less-coarse punctation, and by its 
strie on the elytra: in size, and glossiness of hue, and general 
appearance it is very near to H. melanarius, Sturm. (according to 
examples in my cabinet) ; but it is in form more oval, not so parallel, 
the punctures on the elytra are slightly more frequent, and in this 
latter species there are no traces of punctate striz ; it is broader, and 
not so long as H. Gyllenhallii, Schiodte ; it is very like a large H. 
pubescens, Gyll., but with finer punctation and other minor differences. 
Its position in our British cabinets should be between H. Gyllenhallit 
and H. melanarius. Among species not hitherto detected as British, 
it would resemble most closely H. incertus, Aubé ; this species, how-

ever, 1s longer, suffused at the margins with rufous, and more 
sparingly and more deeply punctured. I know no other species to 
which it is possible to refer this form, except perchance H. genicu- 
latus, Thomson, and H. acutangulus, Thomson, of which I regret 
that I have no knowledge. 

Of the examples before me, two were taken in a stream in Brad- 
gate Park, Leicester, by Dr. Power, in August 1855; one in a stream 
at Black Park, Uxbridge, in August 1856, also by Dr. Power ; and 
one in a stream in Tilgate Forest, by Mr. Brewer. In the cabinets

XXXV.—Deseription of a remarkable Species of Singing Cricket 
(Locustarie) from the Amazons, supposed to be new to science. By 
H. W. Bartss, Esq. 


Order ORTHOPTERA. 


Family Locustariz, Latreille. 
(Gryllide, Leach, Westwood). 


Genus CuLorocetus*, n. gen. 


Palpi with their terminal joints elongate, gradually and slightly thickened 
towards their tips; the maxillaries more than double the length of the 
labials. Prothorax rather short ; surface plane, sloping upwards poste- 
riorly, without ridges or spines, but with a transverse central furrow ; 
sides vertically deflexed; hind margin slightly produced in the middle, 
and rounded. Pro-, meso-, and metasterna of moderate breadth, each 
armed with a pair of corneous tooth-like processes. Antenne setaceous, 
not so long as the body; basal joint oblong, thick, its external anterior 
angle slightly produced. Zegs moderately Jong, stout; the thighs fur- 
nished beneath with a row (the anterior with two rows) of very small 
denticulations; the tibize angular, and also finely denticulate or spinose 
beneath ; the anterior thighs are arcuate above, which makes them 
broader in the middle than at either end ; the hind legs ure short com- 
pared with their usual length in this family, reaching only 2 or 3 lines 
beyond the tips of the closed elytra. Head large, with an obtuse point 
between the antennz ; forehead nearly square, the sides with a smooth 
longitudinal ridge. Eyes small, globular. Elytra of parchmenty 
texture, extremely broad and convex, giving to the insect, when closed, 
a bloated, vesicular appearance ; they surpass the abdomen by nearly 
one-half their length, and are obtuse and rounded at their tips; the 
longitudinal nervure is strongly bent before the middle of its course ; 
the broad costal space is crossed by a number of long transverse nervures,

from the Amazons. 475 


and the rest of the surface is reticulated, the areoles being very large 
and mostly quadrangular. Wings much shorter than the elytra, the 
median neryures strongly flexuous. 


The stridulating-organs of the male (the only sex known) are of 
elaborate construction. They are formed, as usual in this family, out 
of the elements of the small basal portion of the elytra which over- 
laps when the wing-cases are closed. This basal part in the right 
elytron (Pl. XXII. fig. 6), which is overlapped by that of the oppo- 
site wing-case, forms in the centre an opake, smooth, horny plate of 
irregular shape, and the margin projects as a quadrangular lobe with 
much-thickened and raised horny edges. The same part of the left 
elytron (Pl. XXII. fig. a) forms a thick horny lobe of quite different 
shape: its edges are not raised, but the under surface is traversed by 
a thick, horny rib, finely scored like a file, which comes in contact 
with the raised edges of the corresponding lobe, and by the rapid 
voluntary movement of the wings is scraped across them, producing 
the very loud notes for which the insect is remarkable. This file- 
like rib occupies the position of a very slender internal nervure 
visible on the elytra of most of the insects of this family. The 
genus is closely allied to Thliboscelus, Serville. 


Chlorocelus Tanana, (Pl, XXII, figs. 1, 2.) 

C. elongato-ovatus vel pyriformis, prasinus, alis pallidioribus: capite im- 
punctato: thorace transverse rugoso. Long. (alis clausis) 2” 3'". ¢. 
The insect in life is wholly of a light-green colour, the membranous 

wings being paler ; it fades after death, and becomes of a dingy olive- 

yellow hue. The head is impunctate; the forehead smooth and 
shining; the frontal tubercle is excavated on its upper surface, 

The prothorax is transversely and feebly rugose ; the central furrow 

is strongly marked, continuing on each side to the inferior margin 

of the pronotum. The abdomen is conical in shape, and has a 

central, smooth, dorsal keel, which is interrupted by a large rounded 

tubercle at the base of each segment. The elytra are of a thin, hard, 
parchmenty nature, and slightly transparent; the basal lobes, as 
before mentioned, are corneous and opake. 

The species is found in the middle part of the region of the Lower 
Amazons, at Obydos and Santarem. It is met with most frequently 
in the drier forests of the Guiana or north side of the river, from 
Obydos to the lower part of the Trombetas, but it is not a common 
insect anywhere. The natives call it anand, and admire it greatly 
for its musical performances, keeping it, when they capture one, in

476 Mr. H. W. Bates on a Singing Cricket from the Amazons. 


a small wickerwork cage, for the sake of hearing it sing. When 
fed with pieces of cactus, the Tanand will live for two or three weeks 
in captivity ; but its song, at first loud and sonorous, and audible at a 
very long distance, becomes gradually feebler, and ceases altogether 
before the end of that time. The individual from which the above 
description is taken was kept by a friend of mine at Obydos in the way 
here related. It used to chirp in the early hours of morning or late 
in the evening. When producing the sound, the bladder-like elytra 
were in a state of rapid vibration ; and the sound produced by the 
swift passage of the file-like instrument of the one wing-case over 
the horny edges of the other had a much more musical tone than I 
have heard in any other Orthopterous insect. It was my impression 
that the thin hard texture of the elytra and the hollow drum-like 
space which they enclosed were the causes of the peculiar resonance 
of its notes. The sounds produced had some resemblance to the 
syllables Ta-na-nd repeated in quick succession, and hence the 
native name of the insect. 

Many excellent observations have been published on the stridula- 
ting-organs of Orthopterous insects by Latreille, Goureau, and others ; 
but the subject is well worthy of further investigation. The asym- 
metrical form of the two halves of the organ, being portions of wing- 
cases, which in all their conditions and variations are usually per- 
fectly symmetrical in insects, strikes me as very curious. The en- 
larged internal nervule which forms the file-like instrument of the left 
elytron in Chlorocelus Tanana exists on the right wing-case also, in 
an enlarged condition, but perfectly smooth: it seems to perform no 
function, but owes its enlargement to correlation. It is highly pro- 
bable that the same nervule in the female of this insect would be 
quite small and feeble, as it is in the females of other alhed species, 
whose males have beautifully elaborated singing-organs of a similar 
nature to that of the Tanana. I was rather surprised to find the 
wing-cases of the male house-cricket perfectly symmetrical. In this 
species a different nervure to that employed in the Tanand is scored, 
but the nervure is scored in the same way on both elytra. 

It is not until after much hesitation that I have decided to describe 
the present insect as new to science. I am by no means sure that 
it is not the Locusta camellifolia, described by Fabricius in ‘ Entom. 
System.’ tom. ii. p. 35. His phrase, “ Elytra magna, concava, 
viridia, nervosa, apice rotundata,” seems to apply well to our species. 
He does not, however, mention the remarkable vesicular appearance 
of the insect. The expression “ concava” is applied by him to the 
elytra of many allied species of Locustariz. The Fabrician species 


Dr. C. Stal on the British Museum Catalogue of Homoptera. 477 


was again described by Serville in the ‘ Histoire Naturelle des 
Orthoptéres,’ p. 443, who instituted a new genus for its reception— 
Thliboscelus. There appears to be no doubt that the two authors 
had the same insect in view : this is partly shown by the expression 
of Fabricius, “‘ Thorax segmentis tribus,’’ which accords with the 
description of Serville, who says, “‘ Disque du prothorax ayant deux 
sillons transverses assez distincts.’’ If this character can be relied on, 
it would show that they had not our species before them; for the 
Chloroceelus Tanana has only one transverse furrow to the prothorax. 
This, however, is the only positive point of difference I can de- 
tect in the lengthy characters given by Serville. Fabricius gives 
“America”? as the locality for his insect; Serville states that his 
specimen came from Brazil. The Thliboscelus camellifolia of the 
British Museum is a North American insect. The generic characters 
of Thliboscelus given by Serville suit well our insect in every point, 
except that they do not include the great convexity of the elytra. 
He mentions their great breadth and obtuseness, and the bent direc- 
tion of the longitudinal nervure (as well as that of the corresponding 
nervures of the wings) ; but these points do not enable me to decide, 
in the absence of express allusion to the striking character of their 
great convexity. It was necessary to give our insect a name in 
order to record the interesting facts relating to its structure and 
habits*, and therefore there was no remedy but to give it a new one. 


XXXVI.—WNotes on the British Museum Catalogue of Homoptera. 
By C. Srix, Ph.D., Stockholm. 


I nave lately been occupied in making some synonymical notes upon 
the species described by Mr. Walker in the British Museum Catalogue 
of Homopterous Insects. I am proposing to publish them. As a 
preface to these notes I offer this paper, in which I desire to make 
some remarks upon the scientific value of these and other works 
which are published as descriptive catalogues of Homoptera. 

The numerous papers of Mr. Walker upon nearly all orders of 
insects have already received their verdict from the most eminent 
Continental entomologists who have made different orders their 
special study. Concerning the papers upon Homoptera, an order of 
insects unhappily having very few students, and still fewer who 
have to study added knowledge, there have only hitherto been pub- 


* These are described in a narrative of my travels which is now nearly ready 


for publication. 
2mu 2 


478 Dr. C. Stal on the British Museum 


lished some synonymical notes by Dr. Signoret upon the Tettigonides 


_ and Cercopides described by Mr. Walker in the Museum Catalogues. 
_ It becomes my duty to furnish to entomologists of all countries some 
| examples of the many errors into which this author has fallen: my 
| conscientious regard for English entomologists, and respect for their 
' scientific knowledge, induces me to publish my remarks in an English 


journal. 

The first remark that I have to make is respecting the nomencla- 
ture of the author. It is ever disagreeable to meet with names badly 
constructed and in no way appropriate; however, I should not have 
stopped at this matter, if the descriptive and scientific parts of the 
papers had had any value at all. Why hundreds of times use such 
terms as basimacula, dorsimacula, quadrimacula, rufi-fascia, albivitta, 
dorsisigna, flavisigna, biplaga, bifascia, unifascia, multifascra, lati- 
vitta, brevivitta, multistriga, &c., when the usual and correct term is 
basi-maculata, dorso-maculata, quadrimaculata, rufo-fasciata, albo- 
vittata, biplagiata, multistrigata, &e.; or such names as basistella, 
speilinea, speicarina, albiplana, biconica, basiflamma, annulivena, 
bifacies, basispes, flosfolic, &c., composed of words each having a 
signification, but which when compounded into one word have no 
signification that can be understood? When Linné named and 
described a Cicada septemdecim, he had good reason for so doing, . 
and every one who knows the history and habits of that species will 
acknowledge the name to be good and appropriate; but when Mr. 
Walker calls a species Dundubia duarum (!!!), and another Dundubia 
decem (!), every one will be only perplexed, and ask why the species 
were not called secunda and decima, names which, if not at all cha- 
racteristic, can at least be understood, and which will not be con- 
sidered completely absurd. 

Now, first, because the terminology is often very obscure and to 
be condemned, and secondly, because the author shows an entire. 
want of knowledge of the first principles of the system, it is very 
often almost impossible to understand, and quite impossible to make 
any use at all of his papers. It is the first and most essential duty 
of a descriptive author to make himself acquainted with the scientific 
terminology ; and if unhappily this rule is not followed out in all 
cases, still such oceasional occurrences are pardonable, and generally 
of minor value, and are not to be compared with those to be met 
with in the works of Mr. Walker. It will be sufficient for me to 
give as illustrations terms that are strictly mathematical, and so well 
known and understood in common life, that it would appear ridiculous 
in any one not to comprehend their signification ; but even such are 


Catalogue of Homoptera. 479 


frequently confounded by Mr. Walker in the most careless manner. 
Apparently as if he were unacquainted with the distinction between a 
solid body and a plane figure, terms belonging to one are frequently 
employed as if they were terms belonging to the other: thus he uses 
the term macula conica for what ought to be, I presume from the 
insect, macula triangularis, margo convexus (or concavus) for margo 
rotundatus (or sinuatus), caput hemisphericum for semicirculare, Ke. ; 
very frequently the transverse neryures of the wings are spoken of 
as upright, nevi erecti, and other nonsense. 

But we can only understand that the entomological papers of Mr. 
Walker are of no scientific value whatever when we examine the 
collections used by him. It will be found almost impossible to 
determine from his descriptions alone such species as are not di- 
stinctly marked by certain patterns of coloration, or by other similarly 
striking characters, and that even in the case where these species 
are placed (at hazard) in the genera, or at least in the group, or even 
family to which they truly belong. Species that are well defined 
may be readily recognized by a description, if they are placed among 
the group to which they in truth belong ; but if the species is placed 
in another group, as a Chrysomela amongst Halticas, or a Vanessa 
among Noctuas, it is impossible, even if the descriptions are truly 
good, to identify it under that position. Any one who will take the 
trouble to investigate the synonymical notes which I propose to 
publish will see that the same, frequently entirely well-known and 
quite constant species is sometimes described fowr, five, sv, and even 
eleven times over! not only under different specific names, but fre- 
quently even as belonging to two or three different genera! and if 
those species which would not to other entomologists probably pre- 
sent even the slightest variety are to be found placed by him in the 
same genus, they are often separated from each other by species that 
have no affinity to them, and which often belong to other very 
distinct genera. Sometimes species are described from specimens in 
very bad condition, mutilated, or so much injured by haying been 
kept in spirits, that they are not suitable for any collection; and 
these cannot be determined in most cases even from the type-speci- 
mens, much less with the help of the descriptions. Some of the types 
described are not in the collection of the Museum. 

A number of species are described as belonging to the genus 
Elidiptera of Spinola, but of these not one truly belongs to that 
genus, nor even to the group to which that genus belongs; the 
species that Mr. Walker has fancifully brought together as consti- 
tuting this genus of Spinola belong, in fact, to seven different genera, 


480 Dr. C. Stal on the British Museum 


and these again to three very distinct groups or subfamilies. In a 
short paper recently printed in the ‘ Journal of Entomology’ (vol. 1. 
No. 5), Mr. Walker has described two new genera; one of them, 
Thessitus, is said to be “allied to” the genus Hlidiptera: this is 
certainly a mistake; the genus has not any relation whatever to 
Elidiptera—not even to any of the genera which Mr. Walker has con- 
founded with that genus in the Museum Catalogue. One other 
genus of that paper, Dechitus, is said to be “allied to” Cotrades, 
and also to Serida, genera founded by Mr. Walker himself; but, 
again, this equally is utterly a misconception, these two genera 
belonging most apparently, by every character of the insects, to 
different subfamilies, and neither of them to the same subfamily as 
Dechitus! The nothing-saying, meaningless characters given by 
Mr. Walker of these two genera are such as will not enable any 
entomologist to determine them without the aid of the figures of Mr. 
Robinson : these at once show us that these two genera are nearly 
allied to, or, if you please, identical with, the genus Hurybrachys, one 
of the most striking forms amongst insects! Several of the species 
described by Mr. Walker under the generic name Elidiptera belong 
to Flatoides of Guérin: certainly in the Catalogue of Homopterous 
Insects in the Collection of the British Museum there will be found 
a great number of species placed in the genus P’latozdes, but not one 
truly belonging to that genus !—the species must be placed in other 
distinct genera, belonging to different groups of the family Futeortna ! 

In the British Museum Collection are three examples of an 
Australian Aphrophora, very striking in form and coloration: one 
of them is described with doubt as a new species of Clastoptera, a 
genus truly belonging to the family Cercopina, but placed by Mr. 
Walker amongst the Jassina; the second specimen he describes, 
also with doubt, as a new species, but places it in the genus Aphro- 
phora; when for the third specimen he fabricates a third new species, 
he seems to be sure that it belongs to the well-known genus Aphro- 
at least there is no sign of doubt given after the generic 
name. It is wonderful to say, that these three examples are the 
same identical species one with the other. 

A very great number of species are described as belonging to the 
genus Ledra, a very curious and distinct genus in habit and cha- 
racters: on examining the species placed in that genus in the 
Museum Collection, it will at once be seen that the greater number 
of species placed there belong not only to other genera, but to genera 


phora 


belonging to some other, and, from the situation of the ocelli, very 
striking groups of the family Jassina. Of the species belonging truly 


Catalogue of Homoptera. 481 


to the genus Ledra, most of them are described twice or thrice under 
different specific names. 

The genus Cewlidia of Germar is perhaps the most striking of any 
in the family Jassina ; and, in my opinion, an entomologist who at 
first sight cannot at once distinguish that genus is not qualified to 
write papers on Homoptera. Mr. Walker describes a number of 
species which, apparently by accident, he places in this genus Celidia 
(and they belong, in fact, to that genus); but a number of species 
belonging to the same genus he describes and places (why, it is diffi- 
cult to imagine) in other genera, such as Bythoscopus and Tettigonia, 
where no one would think of looking for them: and again, when he 
describes a new genus, Daridna, not at all distinct from Celidia, 
which belongs to Jassina, why place that genus Daridna in the 
family Fulgorina, the most natural and the most striking of all natural 
groups of insects ? (!)—and again, when he describes another new 
genus, Gabrita, which probably will not prove to be distinct from 
Celidia (as the latter genus contains the typical species of Gabrita, 
described for a second time and under another specific name), why 
does he place those two genera in two different groups of the family 
Jassina ? 

It is very painful to be compelled to make these strictures. I have 
confined myself to a few: were I to mention all that I have observed, 
it would require a volume to enumerate them. The above examples 
will prove that the Catalogues are so deficient in scientific value, that, 
I trust, they will be declared non-existing ; and all serious ento- 
mologists will, with myself, regret that the Catalogues of Homoptera 
published by the British Museum, and the descriptions of the fine 
collections of these insects made by Mr. Wallace, have been the 
work of an entomologist not at all acquainted with that order of 
insects. 

I am obliged to the British Museum and to the gentlemen of the 
insect department for the great courtesy and attention that I have 
received while studying this group. I desire to manifest my sense 
of the consideration which has been accorded to me; I cannot do so 
better than by offering myself as the person who earnestly asks them 
quietly and for ever to withdraw, for the sake of science, these 
volumes of their Catalogue from the light of day. 


[The concluding sentence of the above critique will probably be 
thought unnecessarily severe ; but as, in our absence from town, the 
article had been distributed in a separate form before we had seen 
it in print, we have, although with great hesitation, allowed it to

remain without alteration. We considered it right, however, to send 
Mr. Walker a copy, in order to afford him an opportunity of making 
his remarks on it (if he considered it desirable to do so), that they 
might be published at the same time as the above. Those who know 
that gentleman’s amiability of character will not be surprised that 
he should shrink from anything involving the possibility of a con- 
troversy ; but he will examine the alleged errors and “ take an op- 
portunity of publishing corrections of them.’’—Ep. |
