POM ENE A483 JOURNAL OF ENTOMOLOGY. No. I.—AprIt 1860. 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. Genus Hatrica.

E. Allard, Parisiis, dicata. 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. (Subgenus Aphthona, Chevr.) 2.

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.

Habitat in foliis plantarum ad rupes locorum editiorum crescentium, preesertim Sempervivi, in ins, Teneriffa et Palma, rarior. 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- B2 4 Mr. T. V. Wollaston on the Halticide of the Canary Islands. 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.

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.

Long. corp. lin. 14-14. 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 6 Mr. T. V. Wollaston on the Halticide of the Canary Islands. 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.

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. 7.

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. 8.

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. 8 Mr. T. V.

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.” 10.

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. 11.

The European L. dorsaks is tolerably common in the north of Lanzarote, where it was taken by Mr. Gray and myself, in grassy Mr. T. V.

But it is the only region in which I have hitherto observed it throughout the Canarian group. 12. Longitarsus inconspicuus, n. sp.

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. 13. Longitarsus fusco-ceneus, Redt. Longitarsus fusco-eneus, Redt., Fna Austr. 535 (1849).

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. 14, Longitarsus Echii, Hig.

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- latis, prothorace ad latera minus recto, et cet.” 16.

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 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 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 12 M. H.

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- * “Note on two Insect-products from Persia,” in Journ. Proceed. Linn. Soc. iii. p. 178 (1859). + See my analogous observations in ‘ Fabricia Entomologica,’ i. 154. M. H. Jekel on the Pollinosity of the Genera Lixus and Larinus. 13 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.

H. Jekel on the Pollinosity of the Genera Lixus and Larinus. 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.

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 24 Mr. J. 8. Baly on the Eumolpide. 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. Spilopyra sumptuosa. (Plate I. fig. 3, 3* lateral view.)

Corpus elongatum, subcylindricum, hirsutum. Type, Trichotheca hirta, Baly. This genus ought to stand close to Adowus, Kirby ; its elongated body, slender filiform antenne, and incrassated anterior pair of femora will separate it from the latter. Trichotheca hirta.

Ir is difficult to form any adequate idea of the number of new forms, to say nothing of new species of insects, which exist in, or are being constantly added to, our cabinets*. Many of these are almost hope- * Mr. S. Stevens has just favoured me with the sight of a collection of Coleo- ptera (perhaps about a thousand species) made by Mr. Squire at Petropolis (a sort of Brazilian Cintra, and a short day’s journey from Rio), and although the district has been repeatedly worked, and Mr. Squire was there scarcely two months, yet the result of his visit has been the discovery of a vast number of novelties and some new forms of a very interesting character. Genera and Species of Coleoptera. 37 lessly entombed in private as well as in public collections, or have long been accumulating in my own. To record the most remarkable, and such, at the same time, as can easily be recognized by figures and descriptions, if confined to a private collection, is one of the objects of this Journal, and the following is the first of a series of papers which will be devoted to the Coleoptera. As it will be im- possible to follow any systematic plan beyond the limits of each paper, a classified list will be given hereafter to diminish this incon- venience. It must not be forgotten that many of the insects to be described 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.” 38 Mr. F.

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.

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.

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.

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.

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 Genera and Species of Coleoptera. 47 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.

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.

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.

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).

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.

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. Ischalia indigacea. (Pl. III. fig. 6.)

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.

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. : Dinorhopala spinosa. (Pl. III. fig. 2.)

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- VOL, 1, F 66 Mr. F. Smith on some new Genera and Species 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 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.

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. 72 Mr. F. Smith on some new Genera and Species 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. 1.

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, 74 Mr, F.

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. 1. Ceratobasis singularis. (Plate IV. figs. 12, 13.)

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.’ Fam. Carabide. Genus Tarts. Clairville, Ent.

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. 86 Mr. T. V.

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.

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, Genus Harpatus.

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.

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. 90 Mr. T.

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.

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.” Fam.

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. 92 Mr. T.

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, Mr. J.S. Baly on sia new species of Chrysomela. 93 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.

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.

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.

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.

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 H 2 100 Mr. F. P. Pascoe on some new or little-known ‘into which M. Lacordaire divides them, the present genus must be arranged in the same group with 7’rogosita proper. 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.

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 Genera and Species of Coleoptera. 101 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.

B. lata, depressa, fusca luteo varia; prothorace transverso, granulato, 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.

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. Rechodes signatus. R. subdepressus, fuscus ; prothoracis lateribus, elytrorumque macula magna albescentibus. Hab, Natal. 104 Mr. F. P. Pascoe on some new or little-known 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 21 lines. 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. Distaphyla mammillaris. (PI. VIII. fig. 4.) D. subcylindrica, picea (vel rufo-brunnea), fortiter punctata, setosa ; pro- thorace antice bigibboso. Hab. Brazil (Rio; Para). Subcylindrical, pitchy-brown (or, in the Rio specimens, reddish- Genera and Species of Coleoptera. 105 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. Genera and Species of Coleoptera. 107 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. Ethelema luctuosa, (Pl. VIII. fig. 6.) 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.

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 ?

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.

S. niger, subnitidus ; prothorace medio lineolato ; elytris apice obtusis, in singulo quadrisulcatis. 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 110 Mr. F. P. Pascoe on some new or little-known outermost costz uniting posteriorly and forming a slightly projecting 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 Genera and Species of Coleoptera. 111 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 punctatis, interstitiis squamulosis. Hab. Natal. 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 3d lines. 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 Genera and Species of Coleoptera. 113 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 longioribus. 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 23 lines. 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 VOL. I. I 114 Mr. F. P. Pascoe on some new or little-known 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. Pharax laticollis. (Pl. VIII. fig. 1.) P. ovatus, fuscus, tuberculiferus, griseo-setosus; antennis capitis latitu- dine zqualibus. 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, Genera and Species of Coleoptera. 115 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. Chorites aspis. (PI. VII. fig. 3.) C. niger, subnitidus, squamis griseis indutus; antennis, palpis pedibusque ferrugineis. Hab. Borneo. Broadly elliptical, black, rather glossy, covered with short erect pale 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. Drscotoma [ Colydide }. Erichson, Natur. der Ins. Deutschl. mi. p. 292. 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 12 116 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.

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 Genera and Species of Coleoptera. 117 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.

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.

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. * Wiegmann’s Archiy, 1842, p. 213. pl. 5. fig. 5.

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 placed. Chariotheca coruscans. (Pl. VI. fig. 7.) C. atra, nitida; elytris cyaneis; corpore infra, antennis pedibusque ferru- gineis. Hab. Moluccas (Batchian). Deep black, smooth, shining; head and prothorax lightly and irregu- larly punctured ; scutellum triangular; elytra rich indigo-blue, seriato- punctate (about nine rows), with numerous smaller punctures irregu- larly crowding the interstices ; antennz not longer than the breadth of the head, reddish-ferruginous, the last five joints with a few short scat- tered greyish hairs; palpi and legs, particularly the tibiz and tarsi, reddish-ferruginous ; body beneath ferruginous, inclining to chestnut. Length 43 lines. Chariotheca litigiosa. C. atra, nitida; elytris chalybeo-cyaneis; antennis tarsisque ferrugineis ; corpore infra, femoribus tibiisque atris. Hab. New Guinea (Aru). Deep black, smooth, shining; head with crowded oblong punctures, often three or four more or less confluent, and then forming short lon- gitudinal folds in the spaces between them; prothorax with small scattered punctures; scutellum rather small, triangular; elytra dark green, punctured as the last ; antennee, palpi, and tarsi reddish-ferrugi- nous ; body beneath, femora and tibize black. Length 44 lines. Rather narrower than the former, the scutellum smaller, the head differently punctured, the colour less brilliant, &e. Charvotheca cupripennis. C. atra, nitida; elytris cupreis ; corpore infra, antennis pedibusque piceis. Hab. New Guinea (Dorey). Deep black, shining; head, especially between the eyes, with many oblong punctures; prothorax irregularly punctured; elytra seriato- punctate, the interstices crowded with very minute punctures, copper- red, the suture rich green; antenne and palpi ferruginous-brown ; body beneath and legs pitchy.

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. Omolipus corvus. (PI. VI. fig. 9.)

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.

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.

Long. corp. lin. 14. 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.” Genus Mimema, noy. gen.

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. 18 136 Mr. T. V. Wollaston on certain Coleopterous Insects 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 from the Cape of Good Hope. 137 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 138 Mr. T. V.

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. (Kby.) Steph., Ill. Brit. Ent. i. 64 (1830). Atomaria Capensis, 1. sp.

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. from the Cape of Good Hope. 139 Fam.

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.

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.

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.

Its ochreo-castaneous hue (the hinder portion of the elytra being alone darker), uneven, subnodulose pro- thorax, and strongly punctured surface, in conjunction with its raised 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.

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. Family Andremidez. Div. ACUTILINGUES. Genus AucocHtora, Smith. 1.

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 399 five. Genus APISTA.

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.

By H. W. Bares, Esq. 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 160 Mr. H. W. Bates on the Endomychide of the Amazon Valley. 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.

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. Mr. H. W. Bates on the Endomychide of the Amazon Valley. 163 § 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 VOL. I. N 166 Mr. H.W. Bates on the Endomychide of the Amazon Valley. 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 2 IN a 168 Mr. H.W. Bates on the Endomychide of the Amazon Valley. 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. 14. Corynomalus interruptus, Gerstaecker, Mon. p. 160. At Obydos, on the Guiana side of the Lower Amazon, in company with C. eenetus. 170 Mr. H.W. Bates on the Endomychidee of the Amazon Valley. 15. Corynomalus cinctus, Fab. ; Gerstaecker, Mon. p. 162. At Obydos ; also at Ega, Fonte Boa, and St. Paulo, on the Upper Amazon. 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 Mr. H. W. Bates on the Endomychide of the Amazon Valley. 171 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. § C.

It is darker in colour than any of the varieties mentioned by Gerstaecker 172 Mr. F. Walker on some undescribed Species 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.

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 * ‘Hssai d’une classification de la famille des Cérambycides, et matériaux pour servir 4 une monographie do cette famille. Pars prima, Sur les Lamiite.” Par M. James Thomson, Paris, 1860. 186 M. A. Chevrolat—Réflewions et Notes synonymiques. 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.

Au retour de divers voyage 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!

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.

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 extrorsum nigris.—Long, 34 lin. Hab.

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 Mr, J.S. Baly on the Phytophaga. 199 4) flexuosa, secunda pone medium (maculis 5) arcuata, positis), nigris ; 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. Diamphidia ornata, (Plate XII. fig. 3.) D. oblonga, crassa, valde convexa, fulva, subnitida ; capitis vertice vittaque inter oculos, antennis, scutello, parapleuris, abdominis segmenti penul- timi macula utrinque pedibusque (femoribus basi exceptis) nigris; thorace transverso, utrinque foveolato, fascia lata pone medium, antice trilobata, maculisque rotundatis quatuor ante medium transversim positis, his singulis ramulo brevi ad fasciam connexis, nigris; elytris pallide fusco-violaceis, utrisque limbo laterali maculis duabus, prima basi prope scutellum, secunda infra humerum, fasciisque submaculari- formibus duabus, una prope medium, altera ante apicem positis, flavis, nigro-marginatis.—Long. 5 lin.

Pedes robusti, antici sub- elongati, ceeteri longitudine perparum paullo decrescentes ; femoribus paullo, posterioribus evidentius incrassatis; fbiis simplicibus, dorso non- canaliculatis, apice paullo incrassatis; fasts tibiarum apici insertis, articulo basali duobus sequentibus longitudine fere eequali, wnguiculis appendiculatis. Prosternwm angustatum, distinctum. 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. Pseudodera wanthospila. P. elongata, modice convexa, subparallela, postice attenuata, rufo-fulva, nitida; oculis, antennis, tibiis tarsisque nigris; elytris gemellato-punc- tato-striatis, utrisque plaga submarginali, ante apicem posita, pallide flava.—Long. 33-44 lin. Hab. Northern China. Antenne inserted between the eyes on an elevated space, the centre of which is traversed by a longitudinal groove: thorax smooth, im- punctate, convex, basal groove deeply impressed, slightly angular, and having a shallow longitudinal impression running upwards on the disk from its apex; it is terminated at either end by a short deep longi- tudinal groove: elytra not wider than the thorax, parallel, narrowed near the apex, their surface smooth and shining ; disk of each impressed with eleven rows of distinct punctwres, the first abbreviated, the second Mr. J. 8. Baly on the Phytophaga. 201 running parallel to the suture, the eleventh sulcate and placed on the lateral border, the others approximating in pairs, and obsolete towards the apex of the elytron; basilar space slightly raised, bounded by a shallow depression.

Fem. Caput minus exsertum, deflexum, subtrigonatum. 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.

No. IV.—Decemse_r, 1861. 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. VOL. I. K 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.

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.

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. Fam. Oryclidz. Genus HETERONYCHUS. (Dej.) Burm., Handb. der Entom. v. 90 (1847). R 2 210 Mr. T. V. Wollaston on certain Coleoptera 3.

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. 4. Microxylobius lacertosus, Woll. Microxylobius lacertosus, Woll., Trans. Ent. Soc. Lond. (1861). 5.

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. 9. Nesiotes syuamosus, n.sp. (Pl.

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. 10.

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. 11.

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.— JoserH 8.

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- 220 Mr. H. W. Bates on the Papilionide 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. ’ a. Lower disco-cellular nervule, especially of the hind wing, more or less atrophied. Subfam. 1. Nymphaline (Nymphalide, Ageronide, Eurytelide, and Morphide (part.) of authors). b. Lower disco-cellular nervule perfect. Subfam. 2. Brassoline. Subfam. Subfam. Subfam. Subfam. . Satyrine. . Danaine. . Heliconine =. oO Or Pe & DO . Acreine. * 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. { The constitution and affinities of the subfamilies Danaine, Heliconine, and 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. t Lepidoptera Scandinavise Rhopalocera, disposita et descripta.

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, Family Papilionide.

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. 10. L. Lysinoé, Hewits. LI. Lysinoé, Hewits. Ex. Butt. Lept. 3, 4.—Ega. Var. 1. Ib. f. 18.—Ega.

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, 11. Z. Humelia, Cram. ©. P. Eumelia, Cram. 280. 3. P. Vocula, Cram. 353 c.v. The commonest species of the genus.

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.

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 hind wing ; it entirely replaces, on the Upper Amazons, the true Phedusa of Para.

It seems to be uncertain whether the description of Linnzus belongs to this species or to the nearly allied North American form, 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. 6. C. Statira, Cram. 9. P. Statira, Cram. 120 c. p. (1779). 3 Q. C. Evadne, Boisd. Sp. Gén. 628, 22 (1836). 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. 1. C. Trite, Yann: P. Trite, Linn.; Cram. 141 c. p. Generally distributed throughout the Amazon region. Note.—It is worthy of remark, in connexion with the fact of the 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 VOL. I. T 240 Mr. H. W. Bates on the Papilionidee 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.

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.

Bates on the Papilionide 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.

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.

The ¢ is distinguishable from the same sex of Elathea by the under- surface heing pearly white, slightly sprinkled with dusky atoms, and by of the Amazon Valley. 943 the posterior black stripe of the fore wing above joining the outer 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.

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.

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.

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.

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’.

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.

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.

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.

Rien de semblable aux caractcres soulignés, sice n’est la 248 M. A. Chevrolat—Réfleaions et Notes synonymiques. 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.

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- 250 M. A.

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.” Page 338.—189. dthomerus fiticornis, Th.

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. Page 341.—191. Scleronotus scabrosus, (Dej.) Th. Voici certes lune des espéces les plus tranchées et dont la description devenait trés facile. Cependant aux traits principaux ci-aprés énoncés par Vauteur on pourrait ne pas la reconnaitre*. 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.

La note insérée par M.

Laporte et Gory, aient pu donner lieu 4 une telle méprise. La manicre si rapide et parfois irréfléchie de travailler de M.

La composition des antennes et la forme de la téte auraient di ne pas lui laisser com- 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. Je ne terminerai pas sans remercier MM. les fondateurs de ce Journal d’Entomologie de m’avoir permis de suivre-sur ce terrain impartial, une polémique que j’aurais désiré pouvoir davantage abréger, mais qui pourtant 4 son utilité, puisqu’il en résulte des rectifications de synonymie.

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.

Chevrolat observe avec raison, 4 cet égard, que le genre Plagionotus, Muls., doit disparaitre et venir en synonymie. + Zoological Contributions, No. 3, Jan. 1844, “On the Arrangement of Insect- 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. Sous-genre Jamxsia, Jekelt.

Chevrolat, p. 192 de ce Journal, donne comme synonyme de cette espéce une Hyps. albilateralis, Pascoe, qui serait décrite ‘ Trans. Ent. Soc. Lond. vol. v. p- 25,’ ce qui est une double erreur. Mr. Pascoe décrit, p. 36 dudit volume, une Hesycha albilatera a “ élytres étroites, 4 épaules 4 peine proéminentes,” caractéres qui, ajoutés a ceux du genre auquel l’auteur la rapporte, ne permettent pas de lui supposer de l’analogie avec la courte et robuste espéce ci-dessus. t Nom @homme: dédié 4a M.

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- * Expéd.

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. t+ Skandinaviens Coleoptera, Lund, 1859. 268 M.

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.

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.

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. Mr. J. S.

Prosternum distinctum. Abdominis segmento basali sequente paullo longiore. 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. Macrolema vittata.

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.

Count Mot- schulsky has indicated this beautiful species, but without giving a detailed description, under the name of Ambrostoma Chinensis, Motsch., in the 2nd part of the Entomological portion of Schrenck’s ‘Reisen im Amur-Lande,’ published at St. Petersburg, December 1860.

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.

XXVI.—WNotices of new or little-known Genera and Species of Coleoptera. By Francis P. Pascos, F.L.S., ke. [Continued from p. 132.] Parr III. Metamsta [Trogositide ]. Erichson, in Germar, Zeitsch. v. p. 451. Melambia maura. M. elongata, atra; prothorace vix transverso, lateribus basin versus rotundatis. Hab. South Africa (N’Gami). Elongate, black; head dull black, closely covered with oblong punc- tures having the appearance of a small granule in the centre of each, mandibles also covered with oblong punctures except at the bifid VOL. I. 2A 320 Mr. F. P. Pascoe on some new or little-known 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. 322 Mr. F. P. Pascoe on some new or little-known 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 326 Mr. F. P. Pascoe on some new or little-known 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. Genera and Species of Coleoptera. 327 Cuartopreryx { Helopide ]. 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. Cypnatevs { Helopidee }. 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. 328 Mr. F. P. Pascoe on some new or little-known Ospara [ Helopide }. Walker in Annals and Mag. Nat. Hist., 3 ser. ii. p. 284. 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 * For a more detailed description of Osdara, see Lacordaire, Gen. de Ooléopt. y. p. 455.

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. Avotrcra [ Anthribidee]. Pascoe, Ann. and Mag. Nat. Hist. 3 ser. iv. p. 431. Apolecta fucata. A, pallide grisea, nigro varia; capite prothoraceque griseo bivittatis ; elytris maculis approximatis; tarsorum articulo primo basi cinerascente. Hab. Ceram. 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 elytra are more or less confluent according to the individual. Mecocervs [Anthribide]. Schonherr, Gen. et Sp. Cureul. i. p. 115. Mecocerus insignis. M. robustus, griseo-ochraceus, atro maculatus ; prothorace paullo longiore quam latiore ; antennis pedibusque atris. Hab. Ceram, 330 Mr. F. P. Pascoe on some new or little-known Robust, with a pale-greyish ochraceous pile spotted with black ; head with two hairy ochraceous stripes in front, the sides below with deep, coarse punctures; prothorax a little longer than broad, slightly narrowed behind, ochraceous, with more or less confluent black spots; scutellum obscure ochraceous ; elytra subparallel, convex, ochraceous, with small black spots, seriate-punctate; legs black, robust, and elongate in dg, with the basal anterior tarsal joint longer than the succeeding ones (of equal length in 2, with the two intermediate joints not longer than the claw-joint) ; body beneath black, the sides of the metasternum and abdomen with a double row of dull ochraceous spots; antenn black, robust, and three times as long as the body in ¢ (not reaching to the base of the prothorax in 9). Length 12 lines. 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.

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. M. subbrevis, griseo-fulvus nigroque varius; antennis pedibusque nigris, his griseo annulatis. Hab, Cambodia. Rather short, with a greyish-yellow pile; head black, an elongate- Genera and Species of Coleoptera. 331 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.

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.

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 334 Mr. F. P. Pascoe on some new or little-known and elsewhere, and which now contain each but a single represen- tative. 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.

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.

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.

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.

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. Axsryna [ Lamiide ]. Newman, Entomologist, p. 289. : Abryna pardalis.

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.

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. § IL.

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.

Wollaston on the Tarphii. 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. 7. Tarphius gigas,n.sp. (PI. XIX. fig. 7.) T. latus, oblongo-quadratus, crassus, granulis squamisque fusco-piceis parce vestitus et fere setis carens; prothorace in medio latiusculo, postice vix sed antice gradatim angustiore, angulis anticis acutis sed emarginatione antica haud profunda ; elytris in disco subhorizontalibus, sat distincte (preesertim ad latera et postice) nodosis (nodis obtusis sub- picescentioribus) ; antennis pedibusque rufo-ferrugineis. Long. corp. lin. 24-25. Habitat in sylvaticis Teneriffe, rarissimus; duo specimina, in montibus supra “ Ponta Anaga” detecta, sola possedi. 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.) T. quadrato-oblongus, subnitidus, granulis squamisque magis nigrescenti- bus parce vestitus et fere setis carens; prothorace mox ante medium latiusculo, postice vix sed antice sat subito angustiore, angulis anticis acutis sed emarginatione antica minus profunda; elytris valde sub- punctato-rugosis, in disco horizontalibus, ad latera et postice valde subnodoso-carinatis (carinis ad apicem in lobum subquadratum pro- ductis, caudam obtusam apice excavatam efficientibus); antennis pedibusque obscure rufo-ferrugineis. Long. corp. lin. 14-2. Habitat Teneriffam, in sylvis editioribus ad “Las Mercedes” et supra Tagananam, sestate haud infrequens. 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.) T. oblongus, postice vix subattenuatus, granulis squamisque maximis sub- cinereo-brunneis densissime vestitus et plus minus asperatus sed setis fere carens; prothorace antice latissimo, postice gradatim angustiore, angulis anticis obtusis; elytris valde carinato-nodosis (nodis posticis maximis et longissime exstantibus); antennis brevibus pedibusque 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. 388 Mr. F. P. Pascoe on the Brenthide. 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 * See Trans. Linnean Soc. 1854, p. 227. 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.

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 VOL. I. 2¥ 392 Mr. F. P. Pascoe on the Brenthide. 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. Mr. F. P. Pascoe on the Brenthide. 393 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. Miolispa suturalis. M. fulva, nitida; elytris prope suturam simpliciter striatis, ferrugineis, striis exterioribus fortiter punctatis. Hab. Amboyna, Batchian, &c. Fulvous yellow generally, but varying in intensity and amount; the head, rostrum, antenne, and anterior margin of the prothorax black, or 394 Mr. F. P. Pascoe on the Brenthidx. 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, perfoliatis, ultimis tribus majoribus. Prothorax subelongatus, antice 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.

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.

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. H, ovatus, brevis, supra convexus, punctatus, rufo-ferrugineus, capite ad 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- tion, supplied to me by Mr. Cumming, from South Australia. 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. Genus 2. Hyproporvs, Clairy. A. Thorace haud striolato. 1. OBLONGI: THORAX ANGULIS POSTICIS CUM ELYTRIS VIX ANGULUM FORMANS. 1. A. Howittw, n. sp. H. latus, robustus, punctatus, rufo-ferrugineus, elytris rufis, fusco-no- tatis, vel fuscis flavo-lineatis. 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. Apparently as abundant as it is a variable species in the south of Australia. Taken near Adelaide and at Melbourne.

H., ovatus, latus, glaber, punctatus, rufo-fuscus; thorace rufo, ad basin fusco; elytris obsolete unistriatis, ad latera et suturam (et apud medium plerumque obsolete) longitudinaliter flavo notatis ; pedibus et antennis rufo-testaceis. 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. | A common insect in the neighbourhood of Melbourne.

H, ovatus, latus, impubescens, punctatus, rufo-fuscus; thorace rufo-flavo, ad basin fusco; elytris latis, punctatis, haud unistriatis, rufo-fuscis ; pedibus et antennis rufo-flavis. 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. From the neighbourhood of Melbourne, 4. H. imterrogationis, n. sp. H. ovatus, depressus, punctatus, nigro-ferrugimeus; thorace fusco, lateribus rufo-flavis ; elytris flavo notatis. Long. corp. 2 lin., lat. 1 lin.

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. 12. H. undecim-maculatus, n. sp. H, ovatus, latus, subdepressus, crebre punctatus, niger vel fusco-niger, rufo-fusco maculatus.

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. 14, H. Bakewellii, n. sp. H. ovatus, latus, depressus, crebre punctatus, flavus; elytris flavis, nigro notatis. Long. corp. 14 lin., lat. $-1 lin. 2H 2 414 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. Moreton Bay. In the cabinets of R. Bakewell, Esq., and the Rev. Hamlet Clark. B.

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.

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.

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.

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.

Of H. Hansardii I have seen only two examples, from the neigh- bourhood of Moreton Bay.

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.

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.

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. 424 Mr. T.

Habitat insulas Canarienses, in Gomera sola adhuc haud detectus. 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 amalgamation of the whole. Mr. T. V. Wollaston on the Canarian Malacoderms. 427 3. Pecteropus angustifrons, n.sp. (Pl. XX. fig. 1.) P. cyaneo-niger prothorace lete rufo, pubescens; capite angusto, ovali, opaco, densissime et minute subgranulato-rugoso, fronte excavato- depressa, oculis minus prominentibus, clypeo pallido; prothorace in disco nitido et ibidem distincte punctulato; elytris nitidis, dense ruguloso-punctulatis ; antennis ad basin pedibusque anterioribus rufo- testaceis, tibiis anterioribus in toto femoribusque ad apicem ipsum plus minus infuscatis; pedibus posticis nigris, femoribus ad basin rufo- testaceis.

Variat prothorace in disco antico interdum nigro-nebuloso. Long. corp. lin. 13-2. Habitat Gomeram, in collibus mox supra Sanctum Sebastianum mense Februario A.D. 1858 ad flores captus. 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 VOL.

In 3 out of the 16 species described below (namely, the A. commixtus, levicollis, and posticus), I have not yet eaptured the males; but I believe, never- theless, that they are strictly members of this genus. § 1.

Habitat Teneriffam, ad flores vulgaris ; ab ora maritima usque ad 8000’ s. m. ascendit, tempore vernali preedominans: var. 8 ad Palmam pertinet. 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. Mr. T. V. Wollaston on the Canarian Malacoderms. 429 5, Attalus pellucidus. A, sp. precedenti similis, sed paulo magis snescens, prothorace nigro (nec rufo), ad angulos posticos (et interdum per marginem ipsissimum basalem) solum subpellucido-flavo. Long. corp. lin. 11-2, Pecteropus pellucidus, Woll., Ins. Mad. 247 (1854). 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. 6. Attalus ovatipenmis, n. sp.

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. 7. Attalus bisculpturatus, n. sp.

Long. corp. lin. 1-14. Habitat Fuerteventuram, Aprili ineunte a.p, 1859 repertus. 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 Mr. T. V. Wollaston on the Canarian Malacoderms. 431 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. 8. Attalus rugifrons, n. sp. A, enescenti-niger prothorace vel in limbo postico vel fere omnino rufo, cinereo pubescens; capite subopaco, densissime et minute subgranulato- rugoso; prothorace nitido, minutissime et parce punctulato; elytris subnitidis, minute et leviter rugulosis (vix punctulatis), pilis nigris erectis longiusculis obsitis; antennis versus basin pedibusque anterio- ribus (margine femorum superiore excepto) rufo-testaceis; pedibus postice nigrescentibus, femoribus infra tarsisque (necnon interdum etiam tibiis) paulo dilutioribus. Variat prothorace vel ad angulos posticos et per basin ipsissimam, vel in limbo latissimo, vel (rarius) etiam fere omnino pallido-rufo. Long. corp. lin. 13-13. Halitat Gomeram, in collibus prope Sanctum Sebastianum mense Febru- ario ineunte A.D. 1858 ad flores repertus. 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. 9. Attalus ornatissimus, n.sp. (Pl. XX. fig. 2.) A. vel cyaneus vel viridi-cyaneus prothorace utrinque latissime pallido- rufo, cinereo pubescens, nitidus ; capite subopaco prothoraceque den- sissime et minute subgranulato-rugulosis ac minutissime punctulatis ; elytris densissime et minute subruguloso-punctulatis, pilis nigris erectis elongatis postice obsitis ; antennis ad basin trochanteribusque plus minus dilutioribus, 432 Mr. T.

Habitat in montibus Palme ; var. 8 ad locos paulo inferiores pertinet. 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. 10.

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. 11. Aittalus commixtus, n. sp.

Long. corp. lin. 1}-vix 13. Habitat Lanzarotam pomalens ad flores illo biarum captus. 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. 12.

Long. corp. lin. 13. Habitat Lanzarotam borealem, cum sp. precedente semel lectus. 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. 13. Attalus posticus, n. sp. A, subparallelus, subsenescenti-niger, prothoracis limbo postico elytro- rumque apice pallido-flavis, minutissime et parce cinereo pubescens, nitidus ; capite magno, convexo, profunde punctato; prothorace niti- dissimo, minute et parce punctulato; elytris brevibus, depressis, minute punctulato-rugulosis, pilis nigris erectis brevibus parce obsitis; antennis versus basin rufo-testaceis ; pedibus piceo-nigris, tibiis dilutioribus. Long. corp. lin, 14. Habitat Fuerteventuram, juxta oppidum Betancuria semel lectus. T have unfortunately but a single example (and that a female one) Mr. T. V. Wollaston on the Canarian Malacoderms. 435 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. 14, Attalus anthicoides, n.sp. (Pl. XX. fig. 4.) A, xneo-niger, prothoracis limbo, elytris in toto (versus basin et suturam gradatim obscurioribus exceptis), antennis versus basin, tibiis tarsisque testaceis, minute sed dense cinereo pubescens, nitidus ; capite protho- raceque subrotundato minute et parce punctulatis; elytris paulo minus nitidis, submollibus, interdum obsoletissime (vix perspicue) subcostatis, densissime et minute punctulatis, pilis nigris erectis longiusculis parce obsitis ; pedibus parum elongatis. Long. corp. lin. 1-13. Habitat Lanzarotam et Fuerteventuram ; vel ad flores vel preesertim sub recremento farris circa basin acervorum tritici sparso, una cum Anthico canarienst et cet. degens. In its general outline, size, and colour this Attalus bears such a curious primd facie resemblance to the Heteromerous
