I. On the Heteronierous Coleeptera of St. Vincent, 
Grenada, and the Grenadines. By George Charles 
Champion, F.Z.S. 

[Read Dec. 4th, 1895.] 

Plate T. 

The present paper contaius an account of the Hetero- 
nierous Coleoptera collected by Mr. H. H. Smith in St. 
Vincent, Grenada, and the Grenadines, under the 
auspices of the West India Exploration Committee of 
the Royal Society and British Association. Mr. Gahan 
(Trans. Ent. Soc. Lond. 1895, pp. 79-140) has already 
dealt with the Longicornia collected by Mr. H. 11. Smith, 
he at the same time giving a complete list of the whole 
of the species of that family known to inhabit the West 
India Islands. It is not pi'oposed to deal with the 
Heteromerous Coleoptera in the same complete manner, 
but merely to give an analysis of Mr. Smith's captures. 
The collections submitted to me for examination contain 
representatives of seventy-five species — Tenebrionidae 
(42), Cistelidfe (4), Lagriidee (2), Pythid® (1), (Ede- 
meridte (8), XylophiHdfe (4), Anthicidae (5), MordeUidas 
(4), Rhipidophoridas (2), and Cantharidae (3). Of this

number forty-nine are described as new, with three new 
genera. No species of the families Pythid^ and 
Xylophilida3 has hitherto been recorded from the West 
Indies. The whole of the genera, which number forty- 
six, with the exception of Lorelus and the three new 
ones, are common to Central America, four (Iccius, 
Mentes, Sosthenes, and Conulia) not being known from 
South America ; sixteen of them, however, have not 
been previously recorded from the West Indies : JJloma, 
Plaiydema, Talanus, Cojndita, XylojMlus, and Anthicus 
are those best represented ; Lorelus is known only from 
New Zealand and Japan, and two of the new geneia, 
Loreloj)sis and Meniviopsis, are closely allied to it. Of 
the total number of species, exclusive of the five cosmo- 
politan forms, ten only are common to Central America. 
Plaiydema scri'pti'penne, Fairm., a well-marked form, has 
only been previously recorded from Madagascar (? in 
error for Macassar), and Damma Island in the Eastern 
Archipelago. Taken as a whole, the Heteromerous 
Coleoptera of these islands show a considerable affinity 
with the fauna of the north-eastern parts of South 
America. The number of endemic genera being very 
few, and the endemic species closely allied to South 
American forms. It may be noted that several of Mr. 
Smith's most interesting captures were attracted to 
"light" at night.

* The Jamaican insect referred by me to this species (Biol, 
Centr.-Am., Col., iv., 1, p. 23), and of which I have recently 
received some additional specimens from Mr. Cockerell, proves to 
belong to another species. The following is a description of it: — 
Epitragtis jamaiccnuis, u. sp. — Oval, convex, pitchy-black, very 
finely, sparsely pubescent, the pubescence partly hidden by a 
dense, mealy, greenish or glaucous efflorescence, the sides of the 
head between the eyes, and the prothorax and elytra, with dense 
patches of ochreous hairs, which are only visible in fresh speci- 
mens ; beneath pitchy-browu, clothed with fulvo-cinereous hairs, 
and with denser patches of yellowish-white hairs ; the legs and 
antennae piceous. Head very sparsely, coarsely punctate in the 
middle, the sides and anterior half more closely and more finely 
punctured, the epistoma ai'cuate-emarginate in front, the sides of 
the front not prominent, the eyes coarsely granulated, the supra- 
orbital carina indistinct. Prothorax transverse, moderately convex, 
trapezoidal, the sides converging from the base and very feebly 
rounded, the angles acute ; the surface unequally punctured — with 
spaces here and there more finely and more closely punctured than 
the other parts, and transversely depressed in the middle before 
the base. Elytra rapidly narrowing from about the basal third, 
somewhat pointed at the apex, slightly gibbous, the disc broadly 
flattened and declivous from a little below the base ; with in- 
terrupted rows of rather coai 8) shallow punctures, the interstices 
fiat on the disc, feebly convex beyond the middle and very 
sparsely, minutely punctate ; towards the sides and apex with

narrower, and with more slender legs ; the elytra 
regularly convex and more finely seriate-punctate, the 
interstices more even. From E. emarginatus and JE. 
sallvdiy Champ., it may be known by the sulcate elytra. 

SCHCENICUS. 

Schcenicus, Leconte, New Sp. Col., p. 109 (1866) ; 
Champion, Biol. Centr.-Am., Col., iv., 1, p. 18. 

Schcenicus hrunneus, n. sp. 

Elongate oval, obscure reddish-brown, with a faint asneous 
lustre, shining, the legs and antennte rufo-ferruginons. Head 
thickly, rather coarsely punctate, the epistoma rounded anteriorly 
and prominent, the sides of the front obliquely converging before 
the eyes, the latter very coarsely granulated, the supra-orbital 
carina sharply defined. Prolhorax convex, strongly transverse, 
narrowed in front, the sides rounded, the hind angles subrect- 
angular, the anterior angles sharp but not prominent, the surface 
thickly, rather coarsely, uniformly punctate. Elytra moderately 
long, wider than the prothorax, subparallel from a little below tha 
base to about the middle and thence rapidly narrowed to the apex, 
the apices somewhat acuminate ; coarsely seriate-punctate, the 
interstices flat on the disc, feebly convex towards the sides and 
apex, and sparsely, very distinctly punctured. Beneath, very 
sparsely punctured ; prosternum abruptly declivous behind ; 
mesosternum gradually declivous in front. Length 9j, breadth 
3^ mm. 

Hah. St. Vincent. 

One specimen. Closely allied to S.patiametisis, Champ., 
but differing from it in its more elongate shape, the less 

scattered, irregular, depressed spaces. Beneath, the sterna excepted, 
thickly punctured; prosternum carinate down the middle, the 
process broad, rounded at the tip, and received by the very broad, 
strongly raised, horizontal, V-shaped mesosternum ; metasternum 
broadly concave in the middle. Length 10-10^, breadth 4-4j mm. 

Ilab. Jamaica (coll. F. Bates ; Cockerell). 

The description is taken from three specimens sent me by Mr. 
Cockerell. Differs from E. aurule/itus, Kirsch, in its more gibbous 
elytra, smaller size, and more sparsely punctured elytral interstices, 
the latter very uneven towards the sides and apex. The sculpture 
of the upper surface is almost hidden by a greenish mealy powder. 



of St. Vincent, Grenada, and the Grenadines. 5 

prominent sides of the front (in S. j-tavamensis the head 
is trilobate in front), the more coarsely granulated eyes, 
the coarser, sparser, and more uniform punctuation of the 
thorax, the sides of which are more rounded, the more 
coarsely seriate-punctate elytra, etc. (S. oculatus, Champ., 
from the Isthmus of Panama, is also an allied form. 
The genus has not previously been recorded from the 
Antilles. 

Schcenicus anlillarum, n. sp. 
Oblong oval, obscure reddish- or pitchy-brown, with a faint 
aeneous lustre, shining, the legs and antennae rufo-ferrugiuous. 
Head thickly, rather coarsely punctate, the epistoma rounded 
anteriorly and prominent, the sides of the front obliquely con- 
verging before the eyes, the latter very coarsely granulated, the 
supra-orbital carina sharply defined. Prothorax convex, strongly 
transverse, narrowing almost from the base, the sides very little 
rounded, almost straight in one specimen ( $ ?), the hind angles 
sharply rectangular, the anterior angles sharp and prominent, the 
surface sparsely, somewhat coarsely punctate, a narrow ill-defined 
space down the middle impunctate. Elytra moderately long, 
wider than the prothorax, narrowing from about the middle ; 
coarsely seriate-punctate, the interstices flat on the disc, feebly 
convex towards the sides and apex, each with a single irregular 
row of very fine punctures. Beneath very sparsely punctured ; 
prosternum abruptly declivous behind ; mesosternum gradually 
declivous in front. Length S^-O^^, breadth 3:^-3§ mm. 

Hah. St. Vincent — south end; Grenada — Windward 
side; Union I. 

Four specimens, apparently including both sexes. 
Very closely allied to S. hrunneus, from which it may be 
separated by the more acute angles to the thorax, the 
sides of which are straighter and the surface less coarsely 
punctured, the elytral interstices more finely and not so 
closely punctate. The general shape is more oval, the 
insect in this respect resembling S. imnamensis. 

Crypticus. 

Grypticus, Latreille, Kegne Anim., 1st edit., iii.,

Crypticus undatus, n. sp. (Plate I., fig. 3.)

brassy lustre ; the anterior margin of the head sometimes ferru-

ginous, the two or three basal joints of the antennae, and the legs, 
testaceous ; the elytra with a strongly angulated oblique fascia 
extending from the shoulder to the middle of the disc, an angu- 
lated transverse post-median fascia, widening outwards, the two 
connected at the sides, an elongate-triangular patch on the disc at 
the apex, excised in front and extending to the suture behind, and 
one or two oblong spots on the disc, flavous or testaceous ; the 
under surface piceous. Head thickly, minutely punctate; antennaa 
about reaching the hind angles of the prothorax. Prothorax 
strongly transverse, gradually narrowing from the base, the sides 
rounded in front, sparsely, minutely punctate. Elytra forming a 
continuous outline with the prothorax, obsoletely and very 
minutely seriate-punctate to about the middle, the interstices

Hah. Grenada — Telescope and Lake Antoine Estates,

Sent in plenty by Mr. H. H. Smith. Allied to 
C maculahis, Champ., from Central America, but 
differing from it in the more intricate elytral markings. 
These latter vary a little in extent ; the two fascite are 
sometimes connected near the suture by a narrow longi- 
tudinal line, which extends downwards to the triangular 
apical mark. In one specimen the suture is brown. 
The antenna3 usually have the two basal joints only testa- 
ceous. The seriate punctures on the elytra are scarcely 
distinguishable. The genus has not previously been 
recorded from the Antilles. Under rubbish on sandy 
sea-coasts (Smith).

in plenty by Mr. H. H. Smith. It has been taken by 
MM. Delauney and Vitrac in the islands of Guadeloupe, 
Grande-Terre, and Les Saintes, and by the Rev. T. A. 
Marshall in Antigua. 

Ctesicles. 

Head sunk into the protliorax up to the eyes, the latter trans- 
verse and completely divided at the sides ; epistoma deeply 
omarginate in front, leaving the labrum exposed ; mentum flat, 
small, widened in front, rounded at the sides anteriorly ; apical 
joint of the maxillary palpi subtriangular ; antennas moderately 
long, the four outer joints distinctly widened ; prothorax trrns- 
verse, strongly bisinuate at the base, and closely fitting to the base 
of the elytra ; scutellum small, strongly transverse ; elytra convex, 
oval, obliquely truncate and slightly emarginate on either side at 
the base, the basal margin raised on either side of the scutellum, 
the humeri more or less obtuse ; mesosteruum feebly excavate in 
front, the sides very little raised ; metasternura very short ; inter- 
coxal process of the abdomen broad, rounded in front ; iuflexed 
portion of the elytra formed entirely of epipleurtE, the latter wide 
in front and extending to the apex ; tibias rather narrow ; tarsi 
sparsely clothed with long fine hairs beneath, the anterior pair in 
the male with joints 1-3 spongy-pubescent beneath and more or 
less dilated ; body convex, apterous, sparsely pubescent. 

Two species are referred to this genus. It is allied to 
Blaj)stinns, but differs from it in the form of the elytra, 
the broader epipleuras, shorter metasternum, apterous 
body, etc. From Opatrinus it may be known by the 
non-trilobate mentum, divided eyes, etc. Also allied, 
but more distantly, to Dlastolinus, Muls. Both species 
live under stones, drift-wood, etc., on sandy sea-shores. 

Ctesicles insularis, n. sp. (Plate I., fig. 2, S .) 

Oblong oval, convex, opaque above, shining beneath, black, the 
antennae piceous, with the apical three or four joints ferruginous, 
the base of the tibiae and the tarsi piceous or pitchy-red ; above

and beneath very sparsely clothed with short, rather coarse, 
yellowish-cinereous hairs, these being semi-erect and bristly on 
the elytra and decumbent on the other parts of the body. Head 
coarsely, closely punctate. Prothorax strongly transverse, rather 
sharply margined, moderately rounded at the sides, widest a little 
before the middle, slightly wider at the base than at the apex, 
obliquely narrowed in front ; the anterior angles rather prominent, 
the hind angles obtusely rectangular ; the surface thickly impressed 
with coaree, round punctures, which are here and there separated 
by irregular smooth spaces. Elytra about two and one-fourth 
times the length of the prothorax, and a little wider than it, 
rounded at the sides, with rows of very coai'se, deep, not very 
closely placed, foveolar impressions ; the interspaces sparsely 
punctate and sharply costate, the costse slightly shining at the top, 
the third and seventh and the second and ninth confluent behind, 
the second, fifth, and sixth scarcely reaching the base, the first (or 
sutural) turning obliquely outwards before the base, leaving a 
triangular depressed space behind the scutellum, and connected 
with the fourth by the basal ridge ; the humeri moderately pro- 
minent. Beneath thickly impressed with excessively coarse 
punctures.

Ctesicles maritimus, n. sp. 

Very similar to C. insular is ; the elytra more opaque ; the pro- 
thorax a little more rounded at the sides anteriorly, the anterior 
angles less prominent ; the elytra more rounded at the sides and 
with the humeri more obtuse, the disc transversely flattened or 
depressed below the base, the seriate impressions not so coarse and 
more numerous, the interstices strongly convex at the sides, feebly so 
on the disc, the fourth more raised than the others towards the base.

SCAPTES. 

Scajites, Champion, Biol. Centr.-Am., Col., \v., 1, 
p. 222 (1886). 

Scaptes ciliatns, n. sp. 

Ovate, convex, black, the upper surface completely covered with 
pale brown, whitish, aud fuscous appressed scales, which form a 
variegated pattern on the elytra (patches of light scales alternating 
with patches of dark scales in irregular longitudinal series), and 
with scattered, short, semi-erect, hair-like scales," which are 
serially arranged on the elytra ; the margin of the prothorax and 
elytra fringed with long, white, hair-like scales, the base of the 
prothorax also ciliate ; the antennae black, yellowish at the tip. 
Prothorax short, rounded at the sides, narrowed in front, and dis- 
tinctly narrowed behind. Elytra oval, three times the length of 
the prothorax, distinctly narrowed in front. Length 4, breadth 
2^ mm. 

Ilab. St. Vincent — south end. 

One specimen. Smaller and more ovate than S. tro- 
jncus, Kirsch (= squamulatus, Champ.), from Central and 
Soutl) America, and also differing from it, and from 
S. cayennensis also, in the longer marginal cilia of the 
thorax and elytra, the thorax distinctly narrowed behind, 
and the elytra more oval. It is probable that the 8. squa- 
mulatus of Fleutiaux and Salle, from Guadeloupe, belongs 
to 8. ciliatns ; their specimen was examined by me some 
years ago. Under rubbish in low- wooded land near the 
sea (Smith).

the elytra immaculate. I have examined one of the types 
of P. chevrolati, kindly communicated by M. Fleutiaux, 
whose specimens were obtained at Pont Pierre, in the 
Les Saintes Is. The insect is narrower and more shining 
than P. dytiscoides, Champ., from the Atlantic and Pacific

Five specimens of the typical form from Grenada, and 
three of the variety from Mustique Island. The type, 
from Grande Anse, in the Les Saintes Islands, has been 
communicated by M. Fleutiaux for comparison ; it 
appears to be somewhat immature. In our specimens 
the last dorsal, and also the last ventral, segment of the 
abdomen is infuscate or black. Under seaweed (Smith). 

OZOLAIS. 

Ozolais, Pascoe, Journ. Ent., ii., p. 457 (1866); Ann. 
and Mag. Nat. Hist., 4th ser., viii., p. 351 (1871). 

Ozolais tuherculifera, n. sp. (Plate I., fig. 1, 6 .) 

Broad, very convex, black ; the upper surface tuberculate and 
sparsely clothed with very short, appressed, hair-like scales, which 
are in great part hidden by an adherent, greyish or brown, scaly 
coating ; the antennae black or reddish-brown, the two basal joints 
usually paler, the club flavo-ferruginous ; the palpi and tarsi, and 
sometimes the femora also, ferruginous or obscure ferruginous. 
Head with the sides of the front subangularly dilated, the space 
between the eyes with scattered smooth granular elevations ; 
antennae moderately long, joint 9 broader than long and nearly twice 
as wide as 8, 1 and 1 i subconnate, strongly transverse, 10 much wider 
than 9. Prothorax very broad, transverse, with the disc gibbous 
and the sides explanate, rapidly narrowing from the middle for-

•wards, and strongly bisinuate at the base, the latter wider than the 
elytra ; the sides coarsely and irregularly crenate, the anterior 
angles greatlj' produced in front, the hind angles sharp and directed 
inwards ; the surface studded with smooth, strongly raised, granular 
elevations, the disc broadly and shallowly grooved down the middle. 
Elytra about twice as long as the prothorax, rounded at the sides, 
gradually narrowing from the middle forwards and rapidly and 
obliquely narrowing behind, very convex, abruptly declivous behind, 
the humeri acute and directed outwards ; the surface studded 
with strongly raised, subserially arranged, smooth, granular eleva- 
tions, which become coarser and more scattered towards the 
suture, and also with irregular rows of coarse, deep punctures, 
which also become more scattered towards the suture and are 
usually completely hidden by the scaly coating. 

^ . Head broadly excavate in front, the sides of the front 
strongly and angularly dilated ; the epistoma armed with a long, 
suberect, flattened process, which is dilated at the tip, the tip itself 
slightly emarginate. 

Length 5f-8, breadth 3:|-4 mm. ( (^ 9 )• 

Hah. St. Vincent — Windward side ; Grenada — Wind- 
sor and Balthazar. 

Numerous examples of both sexes. This species is 
not very closely allied to any of those from South 
America described by Pascoe, or to the Central- American 
forms described by myself. 0. clongata, Champ., from 
Nicaragua, has a somewhat similar cephalic horn in the 
male ; but the horn in that species is placed on the 
vertex, whereas in 0. tuherciilifera it arises from the 
front of the epistoma. The smooth granular elevations 
of the surface arise from tubercular elevations, the inter- 
spaces being covered with a scaly incrustation, which 
hides the sculpture and the very short, fine, hair-like 
scales. In rotten wood and under logs (Smith).

horn, the apex of which is furnished with a few fulvous hairs, the 
epistoma also with a conical prominence in the middle in front. 

Length 2-2^ mm. 

Hab. St. Vincent — Kingstown. 

Two males and one female. Three others (all males), 
from Guadeloupe I., are contained in the collection of 
M. Fleutiaux of Paris. This insect resembles the 
European PentaphyUus testaceus, Hellw. ; but diH'ers 
from it in having the antenna? gradually widened from 
the fifth joint, the eyes emarginate, etc., as well as in 
its more parallel shape. It has the facies of a Cls. A. 
cioides and A. jpentwphylloides, Champ., from Central 
America, and A. hituhercuJata {0\\\.), axe allied forms; 
the latter has been introduced into France in an exotic 
boletus. From A. cioides, its nearest ally, it may be 
known by the single tubercle on the epistoma in the 
male, the closer punctuation, etc. Found " in boleti " 
in the old Botanical garden (Smith). 



Platydema.

Platydema piliferum, n. sp. 

Broad oval, moderately convex, opaque ; black or brownish. black, 
the suture sometimes paler; the antennae brown or pitchy-brown, with 
the basal joints, and also the apical one. ferruginous ; the anterior 
margin of the head, the labrum, palpi, and legs ferruginous ; the 
under surface ferruginous or piceo-ferruginous ; the elytra clothed

with short, fine, yellowish-cinereous pubescence. Head and pro- 
thorax thickly, obsoletely punctate, the latter very short and 
rapidly, arcuately narrowing from the base, the eyes widely 
separated ; the antennae moderately elongate, joints 7-10 slightly 
broader than long. Elytra a little flattened on the disc, tinely 
punctate-striate, the interstices flat on the disc, feebly convex at 
the sides, and obsoletely punctate. Length G^-7|, breadth 
3-3| mm. 

Hah. St. Vincent — Richmond Estate, on the Lee- 
ward side, and Bovi^-wood Valley near Kingstown. 

Four specimens. Allied to P. sobrinum, Chevr., from 
Central America, but differing from it and the numerous 
allied Tropical-American forms in the very distinctly 
pubescent elytra, the pubescence being visible even in 
rubbed specimens. This character is quite unusual in 
the genus, though many of the species when in fresh 
condition are clothed with a sort of pruinosity which 
soon becomes abraded. The punctuation, that of the 
strias excepted, is scarcely visible, except under a strong 
lens, and the surface is very dull. In a rotten log 
(Smith). 



Plafydema apicenolatum, n. sp. (Plate I., fig. 5.) 

Short ovate, rather broad, convex, opaque ; black ; the anterior 
part of the head, the oral organs, the antennaj, the lateral margins 
of the prothorax, the scutellum, and epipleurjB ferruginous ; the 
elytra each with four sharply-defined flavo testaceous spots near 
the apex — one, very small, on the 5th interstice at about one-third 
from the apex, one, slightly larger, on the 3rd interstice, nearer 
the apex, one, rather larger and oblique, at the sutural angle, and 
one near the lateral margin above this, transverse and equalling it 
in size ; the legs ferruginous, the tibise slightly infuscate ; the 
under surface pitchy-black. Head thickly, very finely punctate ; 
antennae extending to a little beyond the hind angles of the pro- 
thorax, joints 7-1 strongly transverse. Prothorax acutely margined 
at the sides, rapidly and arcuately narrowing from the base, more 
than twice as broad as long, almost smooth. Elytra forming a 
continuous outline with the prothorax, acutely margined, finely 
punctate-striate, the interstices flat and almost smooth. Length 4, 
breadth 2\ mm.

Of this peculiar little species one specimen only was 
obtained ; it was attracted to " light." In general shape 
the insect somewhat resembles P. rotundatam, Chevr. 
In the markings of the elytra it differs from all the 
American species of the genus known to me.

Hah. Grenada — Soubise, on the Windward side. 

One specimen, agreeing perfectly with the type, which 
is supposed to have been found in Madagascar (or ? 
Macassar), and with an example found by Mr. J. J. Walker 
in Dammal.in 1891. Also recorded from India, Siam, 
Java, and Macassar by Mr. Waterhouse, who incorrectly 
ascribes the species to Chevrolat. The insect must have 
been introduced into the island of Grenada. Under 
piles of decaying wood on the coast (Smith). 

LOBELUS. 

Lorelus, Sharp, Ent. Monthly Mag., xiii., p. 76 (1876). 

The four described species of this genus are all from 
New Zealand. The following insect merely differs from 
L. priscus, Sharp, in having the penultimate tarsal joint 
more feebly excavate above, and the limbs less elongate. 

Lorelus hrevicornis, n. sp. (Plate I., fig. 6.) 

Elongate, rather depressed, shining, glabrous, castaneous, the 
prothorax and elytra (the suture, humeri, and apex excepted) 
suffused with piceousin one example, the legsferrugineo-testaceous. 
Head thickly and rather coarsely punctate, the eyes not prominent ; 
antennre short, not reaching the base of the prothorax, moderately 
stout, the joints closely articulated, 3 a little longer than 2, 4-8 
short, gradually decreasing in length, 5-8 transverse, 9-1 1 broader 
than those preceding, 9 and 10 transverse, 11 short-oval. 



of St. Vincent, Grenada, and the Grenadines. 15 

Prothorax wider than the head, truncate at the base and apex, 
rather convex, strongly transverse, widest in front, the sides some- 
what obliquely converging f i-om the apex to the base, the margins 
feebly crenulate behind, the anterior angles distinct but rather 
obtuse, the hind angles minutely prominent ; the surface punctured 
like that of the head, the punctuation a little sparser on the disc 
than at the sides. Elytra considerably wider than, and fully three 
times the length of, the prothorax, truncate at the base, subparallel 
to a little beyond the middle and rapidly narrowing thence to the 
apex ; coarsely, thickly, confusedly punctate, the punctures 
coarser than those on the head and prothorax. Beneath sparsely, 
finely punctate. Legs short, the penultimate joint of the tarsi 
feebly excavate above for the reception of the base of the apical 
joint. Length 2^-3^ mm. 

Hah. St. Vincent — Leeward side ; Becquia I. 

One example from eacli locality ; I have also seen 
specimens of it from Guadeloupe, in the collection of 
M. Fleutiaux of Paris. One of these latter is labelled 
as having been found in the stems of a Cissus, a shrub 
allied to Vitis. In rotten cacao-husks (Smith). 

LoEELOPSis, n. gen. 

Penultimate tarsal joint strongly lamellate, extending beneath 
the apical joint to about its middle. Epistoma separated from the 
front by a distinct groove. Eyes small, rather prominent, entire, 
projecting far beyond the antennary orbits. Prothorax as long as 
broad, trapezoidal. Body pubescent. The other characters as in 
Lorelus, Sharp. 

The single species referred to this genus possesses all 
the structural characters of Lorelus, except as regards 
the strongly lamellate penultimate tarsal joint and the 
distinctly separated epistoma. It has somewhat the 
facies of various Goniaderides and Heterotarsides, but 
differs from them in the closed mesocoxal cavities, 
absence of the trochantin, etc. The body in fresh 
specimens is clothed with very fine, long, erect hairs, 
which are easily abraded. The elytra are very much 
wider than the thorax, gradually widened for two-thirds 
of their length, and confusedly punctate. The thorax is 
widest in front. The antennee have the apical three joints 
widened. Like Lorelus, Menimus, and Menimopsis, the 



16 Mr. G. C. Champion on the Heteromerous Coleoptera 

genus does not agree satisfactorily with any of Lacordaire'a 
groups, 

Lorelopsis pilosus, n. sp. (Plate I., fig. 7.) 

Elongate, flattened above, shining, when fresh somewhat thickly 
clothed with very fine, long, erect hairs, which are easily abraded ; 
piceous or brown, the antenn.-e and legs ferruginous. Head 
thickly, somewhat coarsely punctate; antennas about reaching the 
humeri, moderately stout, the joints closely articulated, 3 much 
longer than 2, 4-8 short, subequal, 9-11 broader than those pre- 
ceding, 9 as long as broad, 10 slightly broader than long, 11 oval. 
Prothorax rather convex, slightly wider than the head, as long as 
broad, truncate at the base and apex, widest in front, the sides a 
little rounded and gradually converging from before the middle to 
the base, the angles somewhat obtuse ; the surface thickly, 
moderately coarsely punctate. Elytra elongate, gradually widen- 
ing from the base to one-third from the apex and there more than 
one-half wider than the prothorax, abruptly narrowing behind; the 
surface coarsely, closely, confusedly punctate, the punctures much 
coarser than those on the head and prothorax. Beneath thickly 
punctate, the punctures very coarse at the sides, the metasternum 
.sparsely and much more finely punctate. Length 3f-4, breadth 
lg-l| mm. 

Hah. St. Vincent — Leeward side. 

Two specimens, one of which is completely abraded. 



Menlmopsis, n. gen. 

Head broad, exserted, slightly raised at the sides above the point 
of insertion of the antennaj, the epistoma well defined ; the eyes 
excessively minute, consisting of about eight facets only, lateral ; 
the labrum prominent ; the mandibles visible from above, emargi- 
uate at the tip ; the apical joint of the maxillary palpi stout, 
securiform. Antennte very short, about equalling in length 
the width of the head, stout ; the joints closely articulated, 
1 fctout, 2 smaller, short, 3-7 gradually increasing in width, 4-7 
strongly transverse, 8-11 forming a well-defined club, 8-10 trans- 
verse, each very much broader and stouter thau 7, 11 short, oval, 
narrower and longer than 10. Prothorax short, truncate and finely 
margined at the base, closely fitting to the elytra, with a sharply- 
defined, projecting, subcrenulate lateral carina. Scutellum short, 



of St. Vincenf, Grenada^ and the Grenadines. 17 

strongly transverse. Elytra the -width of the prothorax at the 
base, and twice its length, with laterally projecting, prominent 
humeri, and a narrow, finely serrate, marginal carina. Legs very 
short, moderately stout ; the tibipe rather narrow, the anterior and 
intermediate pairs slightly rounded on their outer edge, the spurs 
short but distinct ; the tarsi 5-, 5-, 4-joiuted, short, clothed with a 
few long hairs beneath, the basal joint of the hind pair very 
short. Coxa? narrowly separated. Prosternum declivous and 
narrowly produced behind, the apex slightly raised. JMetasternum 
short. Intermediate coxal cavities closed externally. Epipleurre 
broad, extending to the fourth ventral suture. Body elongate- 
oval, probably apterous. 

The single peculiai' species from whicli the above cha- 
racters are taken is closely allied to the genus Menimus, 
Sharp ; but differs from it in having the antennno 
11-jointed, with a 4-jointed club, and also in the 
laterally projecting humeri and shorter legs. The 
eyes are excessively minute, smaller even than in 
Menimus csecus, Sharp. The genus Menimus contains 
numerous representatives in New Zealand, and one in 
Japan. 



Menimopsis excsecus, n. sp. (Plate I., figg. 17, 17a, 9.) 

Rather narrow and somewhat depressed, rufo-testaceous, shining, 
almost glabrous (probably clothed when fresh with scattered, long, 
fine, erect hairs, a few of which are visible upon the head and pro- 
thorax) ; the legs and antenna; testaceous. Head with widely 
scattered coarse punctures ; antennae with a few fine bristly hairs. 
Prothorax strongly transverse, about one-half wider than the head, 
inoderately rounded at the sides, a little narrowed in front, th ; 
anterior angles obtuse, the hind angles subrectangular, the surface 
sparsely, coarsely punctate. Elytra parallel to near the middle and 
arcuately narrowing thence to the apex, the apices conjointly 
rounded ; with rows of coarse punctures, which become finer at the 
apex, the interstices smooth and flat. Beneath very sparsely, 
coarsely punctate, the propleura^ smooth. Length 2|, breadth 
1 mm. (?.)

tudinally convex, subquadrate, a little broader than long, slightly 
rounded at the sides in front, the angles obtuse ; sparsely, finely 
punctate. Elytra of the same width as, and about two and one- 
fourth times the length of, the prothorax, parallel to beyond the 
middle, finely seriate-punctate, the interstices each with a row

of exceedingly minute punctures. Anterior tibife widening out- 
wards, sharply denticulate on their outer edge. Length 3-3^, 
breadth |-| mm. 

Hah. St. Vincent — Leeward side. 

Two specimens. This and the following species have 
quite the facies of a Corticeus (HyjwjMoeus), from which 
genus they may be known by the form of the anterior 
tibise and by the elytra completely covering the abdomen. 
In the typical species from Central America the man- 
dibles are furnished with long ei^ect horns in the male, as 
in Gnaihocerus, Echocerus, etc. The insects here described 
are without these appendages, and they are probably all 
females. 

Icclns grenadensis, n. sp. 

Closely allied to I. rufotestuceus, and differing as follows : — The 
head shorter, the sides of the front narrower ; the epistoma limited 
behind by a deep transverse groove, terminating laterally in a 
rather deep fovea ; the antenna) with joints G-10 very strongly 
transverse, 5 transverse but much narrower than G. Prothorax 
shorter, much broader than long, and more finely punctured. 
Anterior tibite narrower, obsoletely denticulate on their outer 
edge. Length 2|, breadth | mm.

Arrlialjivus debills, n. sp. 

Moderately convex, shining, piceous or castaneous, the antennaj 
ferruginous. Head coarsely punctured, deeply, transversely 
depressed in front, the sides of the front swollen and moderately 
prominent. Prothorax strongly transverse, about equal in -width 
at the base and apex, the sides slightly rounded and sharply 
margined; coarsely, somewhat closely punctate. Elytra twice the 
length of the prothorax, arcuately narrowing from about the 
middle ; coarsely and deeply punctate-sulcate, the interstices 
convex at the sides, flatter on the disc, and with a few very minute 
widely scattered punctures. Anterior and intermediate tibice 
rather coarsely denticulate on their outer edge, the anterior pair 
widening outwards. 

$ . Head broader, with the sides of the front more dilated, 
oblique, and extending outwards nearly as far as the eyes. 
Length 2^-3^, breadth 1-1^ ram. (,??.) 

Hah. St. Yinceut; Grenada — Balthazar, on the 
Windward side. 

Numerous examples. This species is almost inter- 
mediate between Arrhahreus, Champ., and Dicedus, Lee. 
The type of the first-mentioned, ^4. cunvexus, Cbamp., 
from Costa Rica and Panama, has much stouter and 
more coarsely denticulate anterior tibiae, and a very 
differently formed head. These characters, however, 
become much less marked in A. guadelonpensis, Fleut. 
and Salic, and the present insect. InDloidiLs the anterior 
tibia) are rather narrow, and the sides of the front are 
not swollen. A. dehilis is smaller and less convex 
than ^4. guadeJoiipensis, and it has the punctuation of the 
thorax and elytra much coarser. FvovaDioedus pitnctatus, 
Lee.,, an insect found under pine-bark in North America, 
it may be known by the prominent sides of the front and 
the wider anterior tibias. A. guadtloupensis and J. delnlis 
would, perhaps, be almost equally well-placed in Dioedus. 
In rotten wood (Smith).

Numerous specimens. A widely-distributed species 
in Tropical America, ranging from Mexico to Peru, but 
not previously recorded from the Antilles. A. castelnaui, 
Fleut. and Salle, from the Island of Guadeloupe, chiefly 
differs from it in having the punctures of the elytral stria3 
coarse and distant from each other. Found under the 
sheathing bases of decaying banana leaves, etc. (Smith). 

Uloma. 

Uloma, Castelnau, Hist. Nat. Ins. Col., ii., p. 220

Uloma sulcata, n. sp. (Plate I., fig. 4, $ .) 

Elongate, subparallel, convex, robust, castaneous or rufo-ferru- 
ginous, shining. Head very short, closely, finely punctate, trans- 
versely grooved in front ; the antennae short. Prothorax much 
broader than long, transversely convex, a little narrower in front 
than at the base, the sides rounded anteriorly and slightly converg- 
ing behind, the angles obtuse ; very finely and rather sparsely 
punctate, the punctuation a little closer towards the sides and 
apex, and with a shallow transverse groove (sometimes obsolete) 
before the base. Elytra two and one-half times the length of the 
prothorax, narrowing from about the middle ; deeply crenate- 
striate, the punctures rather coarse, shallow, and somewhat 
distantly placed ; the interstices strongly convex throughout and 
sparsely, minutely punctate ; the humeri swollen and projecting 
in front ; the epipleurse extending to the apex. Fifth ventral

elongated, fully twice the length of the tarsi, and bowed inwards 
from near the base. 

Length 7§-ll, breadth 3^-4^ mm. ( ^ ? .) 

Hah. St. Vincent — Kingstown, Windward side and 
Leeward side. 

Ten specimens, varying greatly in size. In the large 
well-developed males the thorax is very convex and 
more rounded at the sides, and the anterior tibiae are 
strongly dilated. Allied to U. iRn-icoUis, Champ., from 
Central America; but differing from it (and from the 
European forms also) in the non-excavate disc of the 
thorax in the males, and also in the form of the tibiae in 
this sex. The fifth ventral segment is foveate in the 
middle in both sexes. The variation in size and develop- 
ment of the males is almost as great as in some species 
of Anisofomidfe. The specimens of this and of the follow- 
ing species of the genus were found under bark or in 
rotten wood. 

Uloma antillarum, n. sp. 

Elongate, subparallel, convex, rufo-ferruginous, shining. Head 
short, closely, finely punctate, and with a very deep transverse 
groove in front ; the antennas short. Prothorax nearly one-half 
broader than long, a little narrower in front than at the base, the 
sides rounded anteriorly and slightly converging behind, the angles 
obtuse ; sparsely, very fiuely, unequally punctate, with a narrow 
space down the middle im punctate, and with a shallow transverse 
groove before the base. Elytra narrowing from about the middle, 
deeply crenate-striate, the punctures rather coarse, shallow, and 
somewhat distantly placed, the interstices moderately convex, and 
with a few exceedingly minute scattered punctures, the humeri a 
little swollen in front. Fifth ventral segment deeply foveate in 
the middle before the apex. 

^ . Anterior tibiae broadly and abruptly widened on the inner 
side from about the basal third, concave beneath, and with a dense 
fringe of short fulvous hairs extending from a little beyond the 
middle to the apex ; intermediate tibiae bowed inwards from 
about the basal third. 

Length 7A-8^, breadth Sf-Sf mm. ( ^ ? .) 

Hah. Grenada — Balthazar, on the Windward side. 



of St. Vincent, Grenada, and the Grenadines. 23 

One male and two females. Closely allied to TJ. sulcata ; 
but less robust, and also differing from it in the more 
transverse thorax, flatter elytral interstices, and more 
deeply grooved head. The male characters are similar. 
The fifth ventral segment is also foveate in both sexes. 

JJloma grenadensis, n. sp. 

Elongate, parallel, very convex, rufo-ferruginous, shining. 
Head very short, closely, finely punctate, transversely grooved in 
front ; the antennaj short. Prothorax nearly one-half broader than 
long, a little narrower in front than at the base, the sides rounded 
anteriorly and slightly converging behind, the angles obtuse ; 
sparsely, finely, unequally punctate, with a narrow space down 
the middle impunctate, and with indications of a shallow trans- 
verse groove before the base. Elytra narrowing from about the 
middle, finely crenate-striate, the punctures closely placed, the 
interstices flat on the disc, feebly convex towards the sides, and 
sparsely, minutely punctate, the humeri a little swollen in front. 
Fifth ventral segment deeply foveate in the middle before the 
apex. 

$ . Anterior tibiaj widened on the inner side from about the 
basal third, concave beneath, and with a dense fringe of short 
fulvous hairs extending from a little beyond the middle to the 
apex ; intermediate tibife bowed inwards from about the basal 
third ; hind tibifc feebly triangularly dilated on the inner side a 
little before the middle. 

Length 7-8i, breadth 3-3^ mm. (^.) 

Eah. Grenada — Black Forest Estate and Balthazar, 
on the Windward side. 

Two males, one of which is considerably larger and 
broader than the other. Differs from Z7. sulcata and U. 
antiUarxnn in the much more finely crenate-striate elytra, 
the punctures of the stria3 closely placed, the interstices 
tiat on the disc; the punctuation of the thorax is dis- 
tinctly coarser, and the hind tibice in the male are feebly 
triangularly dilated on the inner side near the middle. 
The thorax is more transverse than in JJ. sulcata. 

JJloma par vula, n. sp. 
Moderately elongate, subparallel, convex, shining ; rufous or 
ferruginous, the scutellum and elytra often fuscous or piceous, 
the elytra sometimes piceous with the suture and shoulders 



24 Mr. G. C. Champion on the Heteromerous Coleoptera 

ferruginous. Head finely, rather sparsely punctate, transversely 
grooved in front ; the antennae moderately long. Prothorax about 
one-half broader than long, much narrower in front than at the 
base, the sides rounded anteriorly and slightly converging behind, 
the angles obtuse ; sparsely, finely punctate, with a narrow space 
down the middle impunctate. Elytra two and one-half times the 
length of the prothorax, narrowing from the middle ; rather 
coarsely crenate-striate, the striifi shallow, the punctures becoming 
coarser towards the sides and finer at the apex, and not very closely 
placed ; the interstices feebly convex and sparsely, distinctly punc- 
tate ; the epipleurse extending to the apex. Fifth ventral segment 
unimpressed. Anterior tibia; widening from the base, becoming 
very broad at the apex, finely denticulate on their outer edge, 
similar in both sexes. 

^ . Head swollen on either side between the eyes, concave in 
the middle ; prothorax with a broad and very deep transversely- 
cordate excavation on the anterior part of the disc, the excavation 
limited posteriorly by a transverse fold, which is slightly depressed 
in the centre. 

Length 4.^-5^, breadth 15-2J mm. ( (^ ? .) 

Hah. St. Vincent — Windward side and Leeward side. 

Apparently a common insect in the island of St. Vin- 
cent. Allied to U. retnsa, Fabr., recorded by Fleutiaux 
and Salle from Pointe-u-Pitre, Grande-Terre, but scarcely 
half the size of that insect, the thoracic excavation in the 
male deeper and differently shaped, the anterior tibias 
similar in both sexes. The colour of the elytra is as 
variable as in that species.

Blapida castaneipennis, n. sp. 
Obscure reddish-brown, the head, palpi, antenna, and legs, and 
the lateral, basal, and apical margins of the prothorax, black ; the 
head and prothorax dull or feebly shining, the elytra shining ; 
beneath darker than above, the prosternum black, the ventral 
surface piceous. Head sparsely, very irregularly, minutely 
punctate. Prothorax transverse, gradually narrowing from about 
the basal third to the apex, parallel behind, the anterior angles 
rounded ; very sparsely, minutely punctate. Elytra elongate, 
broad, gibbous towards the base, and with the disc flattened and 
gradually declivous thence to the apex, the apex of each elytron 
very sharply mucronate ; very deeply striate throughout, the striae 
finely punctured, the 3rd and 6th near the apex, and the 4th and 
5th, and also the 7th and 8th, at some distance before this, coales- 
cent ; the interstices smooth and convex. Beneath almost smooth. 
Intermediate tibias widened on the inner side at the apex. Length

i&land of Trinidad by Mr. Broadway. Allied to B. neo- 
trojncalls, Champ., from Central America, but larger and 
differently coloured, the thorax more narrowed in front, 
the elytral striae more finely punctured and the interstices 
more convex. B. pertyi, Cast., from Brazil, is also an

Very elongate, narrow, convex, shining, brownish-bronze. Head 
thickly, unequally punctate, the epistoma smoother, transversely 
grooved in front. Prothorax convex, nearly one-half broader than 
long, completely margined at the base, the sides feebly sinuate — 
almost straight when viewed from above ; the anterior angles 
very prominent but rather obtuse, the hind angles acute ; the 
surface somewhat thickly, moderately finely punctate, a narrow 
space down the centre excepted, and feebly transversely grooved 
in the middle before the base. Elytra about five and one-third 
times the length of the prothorax, gradually narrowing for about 
three-fourths of their length, and thence rapidly converging to the 
apex, the apices sharply mucronate and divaricate ; rather coarsely 
seriate-punctate ; the interstices smooth, almost flat on the disc, 
convex at the sides and apex. Posterior tibias similar in both sexes. 
Length 15-16A, breadth 2^-25 mm. ( ^ ? .) 

Hab. St. Vincent — Leeward side; Grenada — Grand

Four specimens. Allied to A. punctlcolle, Champ., 
from Chiriqui, but differing from it in the broader and 
sharply transversely-quadrate thorax, the sides of which 
are almost straight, and the angles very prominent; 
the head and thorax are also much more sparsely 
punctured. From A. cliahrieri, Fleut. and Salle, from 
Guadeloupe I., it may be known by the divaricate and 
sharply mucronate apices of the elytra, and the prominent 
anterior angles of the thorax. The posterior tibia? are 
simple in the male. On foliage (Smith).

T. crihrarius ; the legs and antennje are shorter, the 
latter with joints 9 and 10 strongly transverse (nearly 
as long as broad in T. crihrarius) ; and the elytra are 
more distinctly striate, with the punctures coarser. The 
male-characters are similar, Miiklin's types were from 
Puerto Rico. Beaten from vines and bushes (Smith). 

Talanus ferrugineus, n. sp. 

Elongate oval, convex, ferruginous, shining. Head closely, 
finely punctate, the epistoma smoother, deeply, transversely 
grooved in front ; antennas short, thickening outwardly, joints 
7-10 strongly transverse, 11 oval, stouter than, and more than twice 
as long as, 1 0. Prothorax about as long as broad, the sides rounded 
in front and sinuate behind, sharply margined ; thickly, moderately 
finely punctate, a space along the middle more sparsely punctured ; 
transversely grooved before the base. Elytra moderately long, 
about twice as wide as the prothorax, gradually widening to a 
little beyond the middle and rapidly narrowing thence to the apex ; 
deeply striate, the stride with oval, coars3 punctures, the sutural stria 
very deeply impressed ; the interstices smooth and convex.

Hah. St. Vincent; Grenada — Balthazar^ and Chantilly 
Estate, on the Windward side. 

Six specimens. Allied to T. guadeloupensis, Fleut. and 
Salle (the types, ?, of which are before me), but entirely 
ferruginous in colour, the thorax with a rather deep trans- 
verse groove before the base, the antennae with joints 
8-10 more strongly transverse. From T. suhexaratus, 
Miikl., from Central and South America, it may be known 
by its more robust build, more oval elytra, and ferrugi- 
nous colour, and also in having the tooth on the anterior 
tibiae placed nearer the middle in the males, the tooth ou 
the intermediate pair being obsolete. Beaten from vines 
and brush ; also attracted to " light " (Smith). 

Talanus l^evicollis, n. sp. 
Elongate, subparallel, convex, subopaque ; black, piceous, or 
fuscous, the legs reddish-brown in light-coloured examples, the 
antennae and palpi ferruginous. Head sparsely, very minutely 
punctate, deeply transversely grooved in front ; antennai short, 
thickening outwardly, joints 8-10 transverse, wider than 7, 11 oval, 
stout. Prothorax a little longer than broad, the sides rounded in 
front and sinuate behind, sharply margined ; sparsely, minutely 
punctate, almost smooth at the sides, and Avith a short oblique 
groove on either side of the middle before the base. Elytra 
moderately elongate, one-half wider than the prothorax, subparalkd 
to about the middle and rapidly narrowing thence to the apex ; 
sharply punctate-striate, the striaa with oval rather coarse punctures 
which become finer towards the apex, the sutural stria very deeply 
impressed ; the interstices smooth and feebly convex.

Hah. Grenada — Balthazar, on the Windward side. 

Two specimens, both attracted to "light." In the form 
of the head and thorax this insect approaches L. {Anxdus) 
delavneyi, Fleut. and Salle, from Guadeloupe Island ; but 
the anteunfe (instead of being subfiliform) have the joints 
from the fourth compressed and widened. L. scapularis.

truncate and acuminate at the apex. Prothorax subquadrate, a 
little narrowed in front, slightly broader than long, narrower than 
the head, thickly, moderately finely punctate. Elytra short, oval, 
nearly twice as wide as the prothorax, thickly, somewhat coarsely 
punctate. Legs rather stout, the hind femora strongly clavate, 
the anterior tibi» bowed inwaixls towards the apex. Length 2-2^,

Hab. Grenada — Mount Gay Estate, on the Windward 
side. 

Two males. Allied to the Central-American X. cindl' 
pe?i?itsand X. chiriqiiensis, Champ., but with shorter and 
less parallel elytra, differently formed antennas, etc. On 
bushes, also flying (Smith). 

Xylojyhilus guttatiis, n. sp. (Plate I., fig. 15.) 

Short and broad, convex, dull ; the head piceous or black ; the 
prothorax ferruginous, with a transverse dark brown fascia across 
the middle, sometimes divided into three spots ; the elytra testa- 
ceous or f errugineo-testaceous, with a common transverse patch at 
the base, sometimes divided at the suture, a spot on the outer part 
of the disc a little lower down, the sides ia front, an angulated 
fascia about the middle, and a transverse mark on the outer part of 
the disc near the apex, dark brown ; the antennte aud legs flavo- 
testaceous, the hind femora infuscate ; the under surface f usco- 
ferruginous ; the upper surface closely, finely punctate, and thickly 
clothed with a fine, sericeous pubescence, which is whitish on the 
head and scutellum, and on the light-coloured portions of the pro- 
thorax and elytra, and brown on the other parts ; the under surface 
also closely punctured and clothed with whitisli pubescence. Head 
short and broad ; the eyes large, occupying the whole of the side of 
the head, rather coarsely granulated, narrowly separated in front in 
the. male, a little more distant in the female; antenjise-^( c? ) 
■moderately long, slender, filiform, joints 1 and 2 stout, subequal,

longer than 10, obliquely truncate at the apex — ( 5 ) shorter and 
with joints G-10 gradually increasing in width, U and 10 about as 
broad as long. Prothorax transverse, nearly as wide as the head, 
with a shallow transverse groove on either side of the disc about the 
middle. Elytra nearly twice as wide as the prothorax, and about 
twice as long as broad, narrowing from the middle, and very 
obtuse behind, without distinct depressions. Legs rather short, 
the hind femora stout ; similar in both sexes. Length l^-lf, 
breadth |-| mm. ( c^ ? .) 

Hab. St. Vincent — Leeward and Windward sides; 
Grenada — Chantilly Estate. 

Twelve specimens, most of which ai-e in a bad state 
of preservation. The description is taken from the 
St. Vincent examples. The two from Grenada are in a 
mutilated condition, and one of them has the dark mark- 
ings much more extended and confluent, so as to leave 
some small whitish-pubescent spots only on the elytra. 
This peculiar little species is allied to X. latlcolUs, 
Champ., and other Mexican forms. Beaten from herbage 
in scrubby forest (Smith).

ceous in front, the eyes black, the antenufe and legs testaceous, 
the posterior femora with a large black spot on the inner face near 
the apex ; beneath piceous or brown, the last two ventral segments

One pail'. This species is more parallel and has a 
relatively wider thorax than most of the American forms 
known to me ; there is no trace of a linear arrangement 
of the punctures on the elytra; the hind femora have a 
conspicuous black spot near the apex. The genitalia of 
the male are exposed ; and from the apex of the abdomen 
there projects a very large, broad, spoon-shaped, mem- 
branous piece — apparently a modified terminal dorsal 
segment, wider than the apex of the abdomen — which 
is furnished with two long seta3 at the apex. Under 
rubbish on the banks of a stream in the forest (Smith).

Moderately elongate, convex, black or pitchy-black ; the autennte 
testaceous, with the apical four joints, and sometimes the base of 
the first also, black ; the elytra with two oblique testaceous fasciae 
— one before, the other beyond the middle, the anterior one 
widening outwards, neither reaching the suture ; the legs pitch}--

Four specimen?. Allied to A. gihhicollis and A. alhl- 
cinctus, La Ferte, and A. clavicornis, Champ., but 
differing from all these in its finely scabrous head and 
thorax, and in having an additional fascia on the elytra. 
The pubescence is sparse and easily abraded. The post- 
median fascia extends obliquely upwards and the ante- 
median one slightly downwards, but they do not nearly 
reach the suture. On bushes in open places (Smith).

Hah. St. Vincent; Grenada; Grenadines — Mustique 1. 

Found in abundance by Mr. Smith in various parts of 
St. Vincent and Grenada, and also sparingly at Mustique 
Island. Recorded by La Ferte from St. Thomas, and by 
Fleutiaux and Salic from Guadeloupe. I have also seen 
it from Trinidad. The markings are frequently indis- 
tinct or partly obliterated. In fresh examples the elytra 
are clothed with scattered, long, erect hairs. Shaken 
from heaps of decaying weeds in cacao-orchards, etc.

Numerous examples of this cosmopolitan insect were 
obtained by Mr. Smith. Recorded from Guadeloupe by 



48 Mr. G. C. Champion on the Heteromerous Goleojitcra 

La Ferte, and from Puerto Rico by Quedenfeldt. It is 
omitted from MM. Fleutiaux and Salle's list of tlie Coleo- 
ptera of Guadeloupe. This insect has recently been 
taken by Capt. Casey '{loc. cit.) as the type of a new 
genus, Hemantus. One of the characters given for it 
m his Table of genera (Joe. cit., p. 641) is taken from the 
form of the mesosternum, which he describes as " variable 
in extent, becoming subgeneric in weight " : I con- 
fess I am quite unable to grasp the meaning of such a 
definition. 

Ant hi CMS grenadensis, n. sp. 

Elongate, depressed, shining, sparsely pubescent ; testaceous, 
the elytra piceous or pitchy-black, each with a broad transverse 
fascia a little below the base and a large ante-apical spot, neither 
reaching the suture, testaceous ; the antennas sometimes with the 
outer joints slightly infuscate, the eleventh pale. Head lai'ge, 
subtriangular, with a few scattered punctures at the sides, the 
occiput grooved in the middle ; the eyes moderately large and 
coarsely granulated ; antennas moderately elongate, rather slender. 
Prothorax as long as broad, a little narrower than the head, the 
sides obliquely converging from about one-third from the apex, 
rounded in front, and slightly dilated at the base ; the surface 
sparsely punctured, canaliculate down the middle, the channel- 
deeply excavate towards tlie base, the base grooved on either side. 
Elytra moderately elongate, about twice as wide as the prothorax, 
feebly rounded at the sides, depressed, finely and somewhat thickly 
punctate. Length 2|-3, breadth ^1 mm. 

Hah. Grenada — Granville, Windward side. 

Four specimens. Allied to A. currax, Champ., from 
Eastern Mexico ; but much more shining, the thorax 
deeply grooved down the middle behind and sparsely 
jumctured, the eyes smaller, etc. Under rubbish on the 
bandy sea-shore (Smith).

Mordella sexguttata, n. sp. 

Comparatively short ; testaceous, the eyes black, the prothorax 
with an oval piceous mark on the middle of the disc extending to 



of St. Vincent, Grenada, and the Grenadines. 49 

near the base, the elytra brownish or piceous, becoming indetermin- 
ately paler on the disc towards the base ; the under surface with 
the sides of the metasternum and of the hind coxas broadly, and 
the first four ventral segments in great part, piceous, or rufo-testa- 
ceous, with the second and third ventral segments only in part 
piceous ; the pygidium in the middle, and the extreme apex of the 
hind tibiae and also that of the first three hind tarsal joints, infus- 
cate or black ; the elytra each with a small rounded spot near the 
suture a little below the base, a smaller one lower down at the 
side, a broad transverse sublunate mark at one-third from the apex, 
and an indistinct apical patch (visible only in certain lights), 
cinereo-pubescent, the rest of the pubescence of the upper surface 
fulvous, that of the under surface fulvous or yellowish-cinereous. 
Antennae slender, rather short, joint 3 very small, much shorter 
than 2 or 4. Elytra rather short, gradually narrowing from the 
base. Pygidium very elongate, slender. Length to end of the 
elytra, 2^ mm. ($.) 

Hah. St. Vincent — Leeward side; Grenada — Bal- 
thazar, on tlie Windward side. 

Two specimens, one of which is without head and 
thorax. This pretty little species is allied to the Central- 
American M. flavonotata, M. nigromaculata, Champ., etc. 
The spots are entirely due to the colour of the pubescence. 
The hind tibias have a single short subapical ridge, as 
usual in Mordella.

Found in plenty in St. Vincent. The insect is widely 
distributed in Central America. It is easily distinguish- 
able by the peculiar sculpture of the hind tibiae and tarsi 
{loc. cit., fig. 20c) and the extremely short pygidium. 

Conalia fulvoplagiata, n. sp. 

Short ; black, the elytra with an oblique fulvous humeral 
patch, the basal joints of the antennae f usco-testaceous, the hind 
tibial spurs flavous ; the pubescence brownish. Antennae short, 
joints 3 and 4 slender, short, equal, 5-11 considerably widened, 
7-10 transverse. Elytra gradually narrowing from a little below 
the base. Pygidium very short, not much longer than the hypo- 
pygium, and not extending beyond the apex of the elytra. 
Length, lf-2| mm. 

Hab. Grenada — Lake Antoine and Mount Gay Estates^ 
and St. George's, all on the Leeward side, and Grand 
Ance, at the south end. 

Eight specimens. The insect is perhaps nothing more 
than a colour-variety of C. ehenina, but as it seems to be 
confined to the island of Grenada, it is advisable to 
name it. 



MORDELLISTENA. 

Mordellistena, Costa, Faun. Eeg. Napol., Mordellid., 
pp. 16, 31 (1854). 

Mordellistena pallida, n. sp. 
Moderately elongate, narrow, rather dull ; testaceous, the eyes 
black, the elytra usually indeterminately brownish at the sides 
below the base, this colour sometimes extending inwards ; the 
extreme apex of the hind tibite, and also that of the first three hind 
tarsal joints, and the oblique ridges, black ; the pubescence fulvous. 
Antennae slender, moderately long, joints 3 and 4 short, equal. 
Elytra moderately elongate. Pygidium very elongate, slender. 
Hind tibiiE with three oblique ridges — two very short, near the 
apex, the other extending obliquely across their outer face from 
the middle to near the base ; first joint of the hind tarsi with three, 
the second joint with two, short oblique ridges. Length to end of 
the elytra, 2-2^ mm. ( ,J $ ). 

Hah. St. Vincent — Leeward side, and Kingstown.

Eight specimens. I have also seen it from Guadeloupe, 
in the collection of M. Fleutiaux of Paris, and from 
Antigua, in the collection of the Rev. T. A. Marshall. 
The anterior tibi« are very slender in the males. The 
peculiar sculpture of the hind tibise is common to several 
of the Central- American species of the genus. The insect 
is nearest allied to M. luteola and M. isahellina, Champ., 
from both of which it differs in its much smaller size, 
shorter antennae, and shorter apical ridges of the hind 
tibiae.

the inner side, the rami decreasing in length outwards. Prothorax 
densely, finely punctate ; the posterior half of the disc transversely 
depressed, the depression limited on either side anteriorly by a 
smooth oblique ridge, in front of which is a smooth space. Elytra 
coriaceous, finely, shallowly punctate, the humeri smooth and 
shining. Abdomen, above and beneath, the first dorsal segment

but differs from it in the flat, feebly carinate, vertex, the 
slender basal joint of the hind tarsi, and the finely and

II. New and little-known Palaearctic Perlidce. By Kenneth 
John Morton, F.E.S. 

[Read Dec. 4th, 1895.] 

Plate II. 

About a year ago I attempted a preliminary revision of 
the palaearctic species of the genus Nemoura, as a 
beginning in the direction of increasing our knowledge 
of the Perlidx. It was then my intention to take up the 
genus Leudra next, but the difficulty of getting materials 
in that genus has led me to postpone treatment of it. 
Additional material has, however, come to hand in 
other genera, and I now submit descriptions of several 
new species belonging to Nemoura, Tieniopteryx, and 
Capnia. 

With regard to Tseniopteryx, as the description of the 
new species will include comparative references to T. tri- 
fasciata, it will, with the addition of appropriate figures, 
serve to make the latter species better known, especially 
as regards the c? structure. Albarda's paper (Annales 
de la Soc. Ent. de Belgique, tom. xxxiii.), dealing at 
length with the nebulosa group, taken in conjunction 
with the following notes and figures relating to T. Eisi 
and T. trifasciata, will practically constitute a revision of 
the European species of the genus, the only species 
excepted being monilicornis, which I have not yet 
seen. 

The addition of another species of Capnia to the 
British list, or rather its separation from the acknow- 
ledged C. nigra, is interesting, and a Capnia from 
Amurland is also described. 

This opportunity is also taken to give a description 
and figures of a curious little form which may yet be 
found in this country. It was described by Rostock, in 
1892, as Capnodes S chiller i ; but as the generic name had 
already been used by Guenee in Lepidoptera in 1852, the 
new term Capnopsis is proposed.

56 Mr. Kennetli J. Morton on 

All those entomologists who assisted me with the 
Nemourse have contributed help with the present paper. 
Special thanks are due to Mr, McLachlan, not only for 
allowing me to examine material which may be called 
classical, but also for many valuable hints relating to 
bibliography. 



Nemoura Sahlhergi, n. sp. 

In the dry insect, head and pronotum are shining blackish ; 
antennte nearly black ; pronotal plate faintly brown on anterior 
margin, indistinctly rugose on middle of disc, about same breadth 
as the head without the eyes, borders ill defined, lateral margins 
receding slightly posteriorly. Meso- and meta-nota also shining 
blackish, abdomen dull black. Legs dingy testaceous, femora, 
and apices of tibi« and tarsi fuscous. Wings greyish, sub-hyaline, 
iridescent, neuration pale fuscous, and faintly clouded with 
fuscous about pterostigma and x nervures ; in the hindwings the 
superior cubitus seems to leave the radius at a considerable distance 
from the basal cell. 

A species of the avictdaris group, not presenting strong cha- 
racters, excepting in the appendages of the i^, which are very 
distinct. Broad at the base, these appendages become more 
slender in the shaft, and at the apex there is a broad membranous 
expansion internally, the chitiuized portion forming an out-turned 
short hook obscurely two-pointed and inwards being produced into 
two long acute spears. Exp. of forcwings, 14 to 17 mm. 

I have seen a number of examples from Utsjoki, in the 
region of Lake Enara, Finnish Lapland, taken by Dr. 
John Sahlberg, to whom I have pleasure in dedicating 
the species. 



Tseniopteryx Risi, n. sp. 

T. trifaseiata, pars. auct. 

Head dark reddish-brown or blackish, antennas blackish, long, 
slender, composed of elongate joints, pronotum blackish, the fore 
and hind margins sometimes reddish-brown, elongate, narrower in 
front than behind ; meso- and meta-nota shining blackish, abdom en 



new and Uttle-hiown Palsearctic Perlidw. 57 

dark reddish-brown ; legs reddish-brown, femora and tibiae tips and 
the tarsi marked with fuscous. Forewings pale grey, sub-hyaline with 
darker clouds, neuration fuscous ; hindwings clearer, slightly dark 
at the tips. In the forewings the number of free nervures running 
from the upper cubitus to the apical margin is usually two. The 
darker cloudings are these : a vague blotch nearer the base, fol- 
lowed by a broad median crescent and a narrow crescent, rarely 
any evidence of an apical blotch. 

In the ($ the ventral plate is large, elongate, lateral margins 
slightly inturned ; apex strongly recurved, its outline rounded and 
entire. The genitalia are complicated and the nature of the 
various parts uncertain ; two spiniform appendages are sometimes 
visible in addition to those shown in fig. 1. Expanse of forewings : 
cJ , 18-22 mm. ; ? , 21-28 mm. 

This insect has long been known to Dr. Eis from 
Switzerland, and held by him to be a good species, con- 
trary to the views of Albarda (expressed in 1889), who 
considered it to be a form of T. trifasciata. It is, how- 
ever, abundantly distinct from trifasciata in which the 
ventral plate of the c? is shorter, the apex excised and 
less recurved. In the present species also the antennae 
are more slender, composed of longer joints, and having 
no moniliform joints like those of trifasciata. The 
smaller number of free nervures arising from the apical 
portion of the upper branch of the cubitus (Albarda's 
nomenclature = upper branch of inferior cubitus of 
Nemoura, Trans. Ent. Soc. London, 1894, p. 574) is 
also a useful character, although perhaps not absolutely 
constant. It is also noteworthy that in trifasciata 
there is usually a dark marking concave inwardly at the 
very apex of the wing, of which marking there is rarely, 
if ever, any trace in T. Risi. 

As indicated, T. Bisi has been found in Switzerland 
(Zlirichberg) by Dr. Ris, and amongst Mr. McLachlan's 
continental material there are ? 's which I refer in the 
meantime to this species from the following localities : 
Albania (S. S. Saunders) ; Pyrenees (Eaton, 10th June) ; 
France (Ardeche, May, Fallou ; Vosges, 20th July, 
McLachlan) . 

In Britain it is probably generally distributed wher- 
ever there are fairly rapid streams. Mr. McLachlan has 
it from Haslemere, Surrey (July) ; Rannoch (between 2nd 



58 Mr. Kenneth J. Morton on 

and 12th June, 1865, McLachlan) ; River Yealm at Corn- 
wood, Devon, 16th May; and Yorkshire (Dunford Bridge, 
18th June). It is the species recorded from Rannoch in 
Ent. Mon. Mag., voh xxvii., p. 47, as T. trifasciata (King 
and Morton), and I have found it in May and June in 
almost every hilly district in Scotland which I have 
visited. 

Tfeiiiopteryx trifasciata, P., is no doubt equally wide- 
spread, but in this country, and probably elsewhere, it 
occurs very early in the season, and is therefore perhaps 
less noticed. In Scotland it is very common in the Clyde 
district in March, and Mr, King and I found it rather 
plentiful at Rannoch in the first half of April last (1895). 
The only British S in Mr. McLachlan's collection is from 
the last-named locality (the late Dr. Buchanan White), 
but the species is well represented from the Continent : 
Meseritz, Posen, Prussia (Zeller, 29th April, 1849 ; one 
of the examples named by Brauer) ; Switzerland (Burg- 
dorf, April, Meyer-Diir) ; Silesia ? (presumably from 
Silesia, as the label is in Schneider's handwriting) ; 
Turin (15th and 16th March, Ghiliani). In my own 
collection are examples from Bohemia and Switzerland 
(Klapalek and Ris, respectively), all taken in March. All 
the British 6 examples of T. trifasciata seen by me have 
the wings much aljbreviated (expanse 13 to 15 mm.), 
whereas Continental $'s have usually well developed 
wings (23 mm.) although there are evidently exceptions, 
one from Turin being short-winged.

Head and thoracic segments in the dry insect shining blackish. 
Antennae blackish, legs and seta) fuscous. Wings sub-hyaline with

the anterior margin of the upper intercubital cellule is slightly 
curved. Joints of sette short. In the ^ the large side pieces of 
the genital apparatus are broad at the base, upturned, and sub- 
acute at the apex, which when seen from above is barbed ; seen 
from the side there is usually visible beneath or within these pieces

a slender curved process, with a slight projection or tooth on its 
under side. The ante-penultimate segment dorsally raised and 
covered with minute points. Exp. of forewings, 12 to 17 mm., 
the $ the larger. 

The S first came under notice from Finnish Lapland, 
whence it was received from Dr. Sahlberg. It is pos- 
sible females were included in a collection previously- 
received from the same valued correspondent, and were 
returned by me as C. nigra. The species was found bj 
King and myself in plenty on the shores of Loch Ran- 
noch in April of this year. Three females from Braemar 
(Buchanan White) appear also to belong here ; they have 
the wings rather abbreviated. The species probably 
also occurs in Switzerland, but the S of the pair in 
Mr. McLachlan's collection (Burgdorf, Meyer-Diir) is not 
in very good condition, and further Swiss material is 
desirable. 

A smaller insect, as a rule, in the $ sex than G. nigra, 
and blacker-looking when fresh. The c^, as far as known, 
is full-winged. As usual, the important distinctive 
characters lie in the $ genitalia, but the points in the 
neuration above alluded to should be useful in separating 
the ? from that of G. nigra, if they are found as constant 
elsewhere as they appear to be in this country. A com- 
parison of fresh material will, I think, show the prothorax 
to be smaller, and with margins more rounded in G. atra 
than in C. nigra. 

It should be noticed that Pictet's figure of the neura- 
tion of G. nigra on pi. i., fig. 6 (Perlides, 1841), has the 
basal end of the lower intercubital cellule comparatively 
broad, while in his fig. 4, pi. xxxix., id. op., the condition 
is more like that usual in G. atra, the earlier figure 
being stated as aberrant in the relative explanation of 
plate xxxix. Further, Pictet says the <? of nigra is full- 
winged. On these grounds some might be inclined to 
hold the species above described (assuming Meyer-Diir's 
examples as belonging thereto) as the true nigra. How- 
ever, according to information from Dr. Ris (in letters), 
male Gapnise, practically apterous, are found in Switzer- 
land, and from this I conclude that the two species exist 
there, and I am inclined to think Pictet may have con- 
fused them. The diSerences in the figures just alluded 
to become therefore of importance, and as the earlier one 



60 Mr. Kenneth J. Morton on 

seems to refer to the species now generally known as 
Capnia nigra, I retain the old name for that species.. 



Gapnia affinis, n. sp. 

Very closely allied to C. atra, and of about the same 
size, but as far as can be judged from the examples, 
which are carded, more brownish in colour of the head 
and thorax, and with wings more greyish and paler 
neuration. 

The genitalia are also on the same plan as in C. atra, 
but difi'er in the following details : the barbed part of 
the side pieces is placed dorsally, so that it is distinctly 
visible when viewed from the side, and the slender curved 
process beneath these pieces terminates simply without 
projection or tooth. 

Thi-ee males and a number of females from Blagowik, 
Amurland (22nd April), received from Mr. McLachlan. 
This insect may only be a race or condition of G. atra', 
but it appears sufficiently well marked to deserve a 
special name.

For the sake of comparison with the species of the 
atra group, a few figures and notes relating to this 
species are given. The number of nervules between the 
costa and sub-costa of forewings is irregular ; one only 
is shown in figure 4, but there may be as many as three 
about the middle of the wing. 

Only limited materials for this species have been 
examined. It is a common species in the Clyde district 
in early spring (March and April). Brauer's Austrian 
types in McLachlan's collection do not seem to differ 
from British examples, and I have seen similar examples 
from Bohemia (Klapalek). Examples from Turkestan

most they can only be considered a geographical race of 
nigra, and females from Mingrelia are large, but other- 
wise not appreciably distinct. 

All the European males seen by me have the wings 
reduced to mere scales^ but the c? from Turkestan has 
effective wings. 

On the discovery of a second British Gaj^nia, the 
Chloroperla bifrons of Newman required investigation. 
Mr. Waterhouse has very kindly compared the single ? 
type in Stephens' collection with both species, and is of 
opinion that on the whole it agrees most closely with 
C. nigra, although the basal end of the lower intercubital 
cellule is hardly in the condition more typical of this 
species. As already indicated this cellule is usually 
distinctly biangulate and rather broad at the basal end 
in C nigra. 



Capnopsis, n. n.

Capnopsis Scliilleri, Rostock. (Berliner Bnt. Zeitschrift,

Generic characters : Hindwings smaller than forewings and 
without any folded portion. Sub-costa terminating about the 
middle of the wing. No transverse veinlets between costa and 
radius, beyond the junction of the sub-costa. Maxillary palpi 
apparently with the two basal joints short, the others long ; 4th 
and 5th sub-equal, the 3rd slightly longer. Antennae sub-setaceous, 
joints elongate, only 3 or 4 at the base shorter, Tarsi with minute 
middle joint, 1st and 3rd joints long, sub-equal. Seta3 very short, 
with 9 or 10 joints only (probably only 7 in the $ if the difference 
be not due to mutilation). 

Description : blackish, shining, clothed with short yellowish 
pubescence. Antennte blackish fuscous, nearly black, clothed 
with short yellowish hairs, with five or six stronger erect hairs at 
apex of each joint. Pronotum about same breadth as head, trans- 
verse, margins all slightly rounded, a distinct border all round, 
disc rugose. Wings greyish sub-hyaline, neuration fuscous. Legs 
fuscous with yellow pubescence. Setae fuscous. In the only ^ 
examined the last ventral segment is somewhat rounded at the 
apex, and from either side of it arises a flattened piece ; these 



62 Mr. Kenneth J. Morton on 

pieces converge, and when seen from the side are upturned and 
triangular in outline ; superior to these pieces and passing between 
the setae is a large upturned tapering process (presumably the 
penis) which appears to have on either side of it a spiniform 
sheath. The $ does not appear to have any salient characters 
at apex of abdomen. Expanse of forewings : $, 9^ mm.; $, 
12 mm. 

Originally described from near Dresden it has since 
been received from Finland, where it has been taken in 
several localities by Sahlberg and Palmen. As its con- 
tinental range is thus considerable, it may yet prove to 
be an inhabitant of Great Britain.

III. On the Relation of Mimetic Patterns to the Original 
Form.^ By Frederick A. Dixey, M.A., M.D., 
F.E.S., Fellow of Wadham College, Oxford. 

[Read Feb. 5th, 1896.] 
Plates III, IV., & V. 

I. The Gradual Growth of a Mimetic Pattern. 

It is now many years ago that Fritz Miiller published 
an answer to those opponents of the theory of mimicry 
who made much of the difficulty of accounting for the 
first advances towards the formation of a mimetic 
pattern. t In the course of this communication he 
pointed out (as indeed Darwin had done before him) 
that mimicker and mimicked might, in many instances, 
be reasonably supposed to have started, not from a 
position of wide divergence from each other, but rather 
with the possession of some feature or features, common 
to them both, which should give material ready to hand 
Tor the assimilative process to work upon. The chief 
instance relied on by Fritz Miiller in support of his 
contention was the well-known mimetic genus of 
Pierine butterflies known as Leptalis or Disniorphia.X 
The black and yellow Leptalis (Dismorphia) melia, 
according to him, was to be regarded as representing 
the primitive type of coloration of the genus ; and 
although it did not itself mimic any other form, it never- 
theless showed independently so much of the character- 
istic Heliconine colours and arrangement of pattern, 
that the complete Heliconine aspect presented by many 
of its near relatives could be derived from it with com- 
paratively slight modification. 

"■ A preliminary abstract of the present paper has appeared in 
the British Association Reports for 1894.

66 Dr. F. A. Dixey on the Relation of 

The instance chosen by Fritz MilUer was unfortunate. 
A wider view of Pierine affinities than he had the oppor- 
tunity of taking would no doubt have led him to the 
conclusion that, after all, the original Lejitalis probably 
was a white or white and black butterfly, and not a black 
and yellow or black and orange insect like Leptalis 
{Dismorphia) melia. Moreover, the position that D. melia 
is not a mimic can hardly be sustained. It bears a very 
considerable resemblance to D. euniara, which is itself 
an almost exact copy of Actinote 'pellenea ; Actinote being 
the neotropical representative of the well-known inedible 
genus Acrsea. There is little room to doubt that D. melia, 
so far from preserving the primitive Leptalis type, has 
diverged to some distance therefrom under the influence 
of mimicry. 

But although Fritz Miiller's principal instance does 
not appear to me to be strong enough to bear the weight 
of argument that he rests upon it, there cannot be much 
question that his contention in the main is perfectly 
sound ; and that, as a general principle, the process of 
mimetic assimilation depends rather on the development 
of old, than on the starting of new features, either of 
pattern or of colour. 

In order to illustrate this principle, I have prepared the 
series of figures shown in Plates III. and IV,, Figs. 1-12. 
These represent an array of facts that I venture to think 
are in many respects of great interest. 

Fig. 1 shows the underside of the male of one of the 
ordinary neotropical non-mimetic Pierines*, a true Pleris 
as that genus is restricted by Dr. Butler — P. locusta of 
Felder. The chief points to be observed are in the 
hindwing. They are (1), the spots or patches of bright 
red which are found at the base of the precostal, median 
and internal spaces respectively (Fig. 1, a, c, d) ; (2) a 
well-defined yellow streak (e) occupying the costal space ; 

(3) a pale central area (/), in many specimens yellowish, 
occupying the region of the cell and the adjacent portion 
of the wing, especially towards the internal border; 

(4) a dark shade (/i, i) on the anal and costal sides 
respectively of the pale central area. The present 
species happens to be a rather heavily coloured member 
of its group, but in other species of the same genus 

* See below, p. 72, note. 



Mimetic Patterns to the Original Form. 67 

Pieris we get a great lightening of the general tone of 
colour, without however losing the essential features now 
referred to. In P. ijhaloe for instance, also a non- 
mimetic Pieris from the same neotropical region, we have 
as it were an attenuated and washed-out version of the 
scheme of mai-king seen on the hindwing of P. locusta. 
Here (Fig. 2) are visible the same basal red patches, 
though now confined to the precostal and internal spaces ; 
the same pale costal streak and central area, now in most 
specimens white rather than yellow ; and on either side 
of the latter the same two dark shades, now reduced to 
a pair of brownish streaks. From either of these types 
to the well-known Heliconine form here represented by 
Heliconius niimata (Fig. 11), seems a sufficiently long 
step ; nor is it at first sight apparent that there is any- 
thing in common between the former and the latter 
schemes of coloration. Nevertheless, while it will be 
allowed on the one hand that the female of Mylothris 
pyrrha (Figs. 9, 10) presents a very good imitation of 
H. numata, it can be shown on the other hand that this 
last-named Pieriue owes its mimetic features to a simple 
development of characters already possessed by the 
other Pierine forms just spoken of, to which it is closely 
allied. 

In order to make this apparent, it will be necessary to 
refer to some of the other neotropical species of the 
same genus Mylothris. This interesting little group, 
comprising besides M. jjyrrha the closely related M. 
malenl-a, M. lypera, and M. lorena, has been more than 
once spoken of by Mr. Wallace* as affording an instance 
of mimetic females associated with males of the ordinary 
white type of Pierine coloration. It is quite true that 
all the males throughout the group exhibit on their upper 
surfaces nothing but the ordinary white character ; Mr. 
Wallace, however, does not mention the curious fact 
that the same males universally show ou the under 
surface, though in varying degrees, an approach towards 
the Heliconine pattern that is so completely imitated 
by their mates. These partially developed features on 
the under surface of the males enable us to trace the 
history of the growth of the mimetic pattern. 

Let us take the underside of the male of Mylothris

68 Dr. F. A. Dixey on the Relation of 

hjpera (Fig. 3), and compare it with that o^ Pierislocusta. 
There is no difficulty in identifying the principal markings 
as before enumerated. The yellow costal streak and 
central area {e,f) and the anterior and posterior dark 
shades {h, i) are present in M. hjpera as in P. locusta, all 
occupying the same relative positions ; the precostal red 
however has disappeared^ and the internal and median 
touches of the same colour have united and prolonged them - 
selves into a triangular streak reaching about a third of 
the way across the wing (cd). A small dark area (g), 
which in P. locusta lies immediately posterior to the internal 
red patch, has in 31. hjpera extended itself in the same 
direction with the extension of the patch, and has, beyond 
the outer extremity of the latter, united with the anterior 
dark area (i) in such a way as to completely surround the 
red patch with a distinct region of black. All the areas 
somewhat vaguely indicated in P. locusta have in M. 
hjpera acquired a distinct and definite character with 
sharply-marked, clear-cut borders. There is no doubt 
of the homology of the markings in the two cases, nor 
does the change from one to the other deserve to be 
called either violent or abrupt. 

The underside of the male of M. lorena (Fig. 4) takes 
us a step onward. Here are exactly the same features, 
but with a further development along the same lines. 
The red patch has now become a definite streak reaching 
half-way across the wing, but still bears the same rela- 
tion to the anterior dark area. The costal streak and 
central area have undergone a similar elongation, and in 
this instance are much paler in colour. The whole aspect 
perhaps recalls that of P. phaloe rather than that of P. 
locusta, and the correspondence with the former insect 
is still further borne out by the presence of a diagonal 
dark streak {Ic) in the forewing, part of which is indicated 
in P. phaloe, uniting the costal with the posterior or 
outer margin. 

The general streakiness of the male of M. lorena is 
preserved or enhanced in the male of M. pijrrlm (Fig. 5). 
There is in this case no diagonal dark band crossing the 
forewing, but the red streak of the hindwing acquires 
additional distinctness and importance, while the banded 
appearance is further increased by a slight change in the 
disposition of the enveloping black. 

As far as the hindwing is concerned, we have now 



Mimetic Patterns to the Original Form. 69 

all but reached the complete mimetic conditiou of 
M. ]?yrrka 9 (Figs. 9, 10), The only thing still wanting 
is an infusion of more or less brownish red into the pale 
yellow or orange of the costal and central streaks. It is 
observable that even in the female M. pyrrha the assi- 
milation between the old red of the basal patch and the 
new red of the costal and central areas is not quite per- 
fect, the former always retaining on the under surface a 
more vigorous and decided tint than the latter (see 
Yig.9,e,cd,f). 

With regard to the forewing, there is no doubt a con- 
siderable interval between the male and female of 
M. pyrrha. An inspection, however, of the female of 
M. lorena and M. malenka (Figs. 6, 7, 8), enables us to 
see how it may be bridged over. Comparing the sexes 
of ill. lorena (Figs. 4, 6, 7), we find that their patterns 
are identical in the main features, though the female has 
an additional dark streak in the forewing (I) running 
parallel with the inner border. The central pale area of 
the hindwing has also in the female almost or entirely 
disappeared from the lower surface, while the other 
spaces on both wings which in the male are white or 
very pale yellow, assume in the female a deeper yellow, 
Avarming towards the base of the wing to an orange or 
brownish red. These changes, comparatively slight as 
they are, are sufficient to give the female M. lorena, a 
decidedly Heliconine aspect. They point out, moreover, 
the manner in which the still more completely Heliconine 
facies of M. malenha 9 (Fig. 8) and if. pyrrha ? 
(Figs. 9, 10) may grow naturally out of the Pierine 
materials already noticed. A very close comparison of 
M. pyrrha with H. numata (Figs. 10, 11) will indeed 
show that the correspondence of markings is not abso- 
lutely perfect in every particular ; nevertheless, the 
general effect is marvellously alike, and if assisted by 
similarity in habits and mode of flight, must be amply 
sufficient for all practical purposes of protection to the 
MylotJiris. 

Looking at this series as a whole, and bearing in mind 
that it would be possible to include other forms * which 
would render the gradation still easier than is shown 



** For example, P. marana and M. lypera % . 



70 Dr. F. A. Dixey on the Relation of 

here, we cannot, I think, feel any doubt that it is suffi- 
cient to demonstrate the possibiUty of the formation of a 
practically perfect mimetic pattern from the ordinary 
form of a quite distinct type, without any violent or 
abrupt changes of design. It does not, indeed, lend any 
support to the view that mimicry can only originate 
between forms that already possess considerable and 
obvious resemblance to one another, nor does it coun- 
tenance the opinion that mimetic changes are eflPected 
jyer saltma. What the series of forms here figured does 
show is that, granted a beginning however small, such as 
the basal red touches in the normal Pierines, an elaborate 
and practically perfect mimetic pattern may be evolved 
therefrom by simple and easy stages. 

II. Sexual Dimorphism in Mimetic Forms. 

There remains, in regard to the foregoing series, a 
question of great interest ; namely, what is the meaning 
of the diversity between the sexes in these more or less 
completely mimetic forms ? Why should the one sex 
have advanced so much further along the mimetic path 
than the other ? It is no doubt the case that the females 
stand in greater need of protection than the males, but 
to say this still leaves several questions unanswered. 
Are we right in regarding the male patterns as perpetu- 
ating stages through which the other sex has also 
passed in order to reach its present state of mimetic 
completeness, or are we to suppose that the selection by 
enemies has affected only the female sex, and that the 
patterns seen on the males are merely an incidental result 
of heredity, being, in fact, a secondary version of the 
female pattern transmitted in a weaker form ? In either 
case, what has checked the further development of 
mimicry in the male ? Is this imperfect development 
simply a passive result of the absence of necessity for 
change, or is there some active force at work preventing a 
further modification ? It is well known that an explana- 
tion of a somewhat similar case has been sought in the 
p? inciple of sexual selection ; the females, it was suggested, 
us the more conservative sex, preferring in their mates the 
ancestral type of coloration of the group.* Mr. Wallace, 

* Belt, " Naturalist in Nicaragua," Ed. 1888, p. .385. 



Mimetic Patterns to the Original Form. 71 

on the other hand, points out that in the Pierine group 
before us the habits of the two sexes are different ; that 
whereas the females haunt the forest glades in company 
with the Heliconii, the males congregate and fly in the 
open with other species of white butterflies, among whom 
a reddish or brownish insect would be especially con- 
spicuous, and would be very liable to experimental 
tasting.* This fact would seem to supply an active check 
on the development of the pattern in the male, but it 
still leaves undetermined the meaning of so much of 
the Heliconine colouring as does exist, and of this 
JVJr. Wallace has offered no explanation. 

I am myself inclined to think that however much it 
may be to the advantage of these male forms to be taken 
under some circumstances for white butterflies of the 
ordinary kind, yet there must be times and occasions — 
probably while the insect is at rest and settled — when 
the partial mimicry of the underside comes into play, and 
tends to afford protection. An instance in support of 
this view exists in Hesperocharis hirlanda (Fig. 12). 
This insect, like the males of those that have just been 
considered, is on the upper surface an ordinary white 
butterfly of the usual kind ; the lower surface, however, 
presents an incipient mimetic pattern of a like degree of 
development with those of Mxjlothris . lorena $ and 
M. iiyrrha 6 . This can be no feeble reflection of a 
mimetic pattern complete in the female, for the sexes of 
H. hirlanda hardly differ; moreover H. hirlanda, with 
one or two other forms probably not specifically distinct 
from it, is the only species of its genus which shows any 
approach towards a mimetic coloration. The mimicry, 
slight as it is, must therefore, it would seem, be of somf> 
service, as otherwise it would in this case be meaning- 
less ; and if this be so with H. hirlanda, it is reasonable 
to suppose that whatever amount of protection such an 
approach to the Heliconiiie pattern confers, is also shared 
by the males of Mylothris. 

A further point of interest that arises in connection 
with H. hirlanda is this — that a mimetic effect which 
generally resembles that of M. pyrrha $ , is here reached 
by different means. Ilesperocharis, like Mylothris, starts 
no doubt from a regular Pierine form, such as that

exhibited by P. pit aloe; but wliereas in Mylothris the 
rnain red streak of the hind wing arises from the internal 
and median basal red, and is central (Fig. 5, cd), in 
Hefsjyerocharis it results from a development of the pre- 
costal and costal red patches, and occupies the correspond- 
ing regions of the wing (Fig. 12, a, h). The precostal 
red is undeveloped in Mylothris, and the median red is 
undeveloped in Hesperocharis. One result of this 
is that in the latter form the relative position of the main 
yellow and red streaks is reversed ; notwithstanding 
which the general resemblance to Mylothris is consider- 
able, and the difference would very probably remain 
undetected by many insectivorous animals. The present 
point has already been noticed by me elsewhere.* I draw 
attention to it here simply because it affords another 
illustration of the gradual growth of mimetic patterns 
from an original non-mimetic form.-f 

III. Recipeocal Mimicry between Inedible Forms. 

In the previous communication to the Entomological 
Society! of which I have already made mention, I drew 
attention to certain facts which I am now able to illustrate 
by PI. v., Figs. 13 and 14, representing the undersides of 
a Pierine [Pereute levcodvosime) and a Heliconius {H. mel- 
pomene) respectively. Both Heliconius and Pereute are, 
it will be seen, furnished with basal red spots, and this is 
the case with very many of the Heliconii and their 

* Trans. Ent. Soc. Lond., 1894, p. 286. 

t Throughout the foregoing remarks, F. plialor and P. Jocusta $ , 
have been spoken of as non-mimetic forms. This is undoubtedly 
the case with P. jilialoo, but it is perhaps possible that even in 
P. locusfa $ , the underside of the hindwing may have (especially 
in darkly-coloured individuals) a certain mimetic value. The 
underside of the hindwing in P. locuda, P. cinerea and some 
others resembles that of IleUconius melpomene and other protected 
species in giving the general idea of a dark wing-area with yellow 
costal or precostal streak and basal red spots. The forewing of 
P. locusta contains a large surface of white, but this would be 
partly or wholly concealed in the resting position. It is true also 
that the yellow streak and red patches do not occupy exactly 
corresponding positions in the Pieris and the Heliconius ; but there 
is abundant evidence to show that while affinity displays great 
respect for the exact position on the wing of any given feature 
of the pattern, mimicry to a large extent disregards this, and aims 
rather at a general similarity of effect. See the instance of 
Hesperocharia hii-landa above, and see also below, p. 74, note.

Mimetic Patterns to fho Original Form. 73 

Pierine imitators. What is the meaning of this coinci- 
dence ? The first answer that suggests itself is that it is 
simply an ordinary case of mimicry ; the red spots belong 
originally to the Ileliconiiis, and the Pierine has acquired 
similar spots in order to complete the mimetic picture. 
Two facts, however, militate against this supposition. 
The first is that these red patches, so far from being 
confined to the mimicking Pierines, are found to have 
a very wide distribution throughout the whole Pierine 
subfamily, existing not only, as we have seen, in non- 
mimetic neotropical forms such as Plerls locusta and 
P. phaloe, but in numerous old-world genera as well, 
reaching a great development in the Indian and Austra- 
lian Delias, and having even left a relic in the common 
white butterflies of our own country. It would be extra- 
vagant to suppose that these widespread characters owe 
their origin simply to the necessity for mimicking certain 
South American Heliconii. Moreover, as I have else- 
where shown, such an origin for the old-world forms as 
this hypothesis would involve is at variance with what is 
known of Pierine phylogeny. The second fact is that 
although several Beliconii which are not the subjects of 
mimicry show marks of the kind, yet they are most con- 
stant, most distinct and most Pierine-like in species of 
Heliconius that serve as models. There must, it would 
seem, be a relation between the two forms which is not 
entirely due to mimicry by the Pierine. Are we then to 
say that the Heliconius is the mimic and the Pierine the 
model ? This would appear to be going against all 
received ideas on the subject, and to be negatived by all 
that is known of the inedible qualities of Heliconius and 
of the ancestral coloration of the Pierines ; nevertheless, 
with respect to the particular marks in question I believe 
that it comes near to the true expression of the fact, and 
I -would suggest that the key to the difiiculty is to be 
found in the following considerations. 

It has been well shown by Fritz Miiller,* whose con- 
clusions have been followed and amplified by Meldola and 
Poulton, that there exist two kinds of mimetic associa- 
tions — in one of which an edible form shelters itself by 
resemblance to another form well known to be inedible, 
this being the aspect of mimicry first detected and 
explained by Bates ; while in the other a group is 
constituted all of whose members are inedible, and join

74 Dr. F. A. Dixey on the Relation of 

forces, so to speak, in order to share the dangers of 
experimental tasting. In the first kind it is obvious that 
the onl}'- imitation must be by the unpi'otected of the 
protected form ; there is no force tending in the converse 
direction. But in the second kind it does not seem to 
have been sufficiently noticed that, especially if the 
numbers of the associated species are approximately 
equal, there may fairly be expected to arise a kind of 
give-and-take arrangement, in consequence of which two 
or more inedible forms may hasten the assimilative 
process by imitating each other. This is my reading of 
the case before us. There are some independent grounds* 
for tbiukiug that the mimicking Pierines in this par- 
ticular group of instances are not, as has been generally 
assumed, edible. It is therefore not unreasonable to 
suppose that being distasteful, like the associated 
Heliconii, and forming with them a company for mutual 
protection, they have both taken from and bestowed on 
them characteristic features of pattern — both sides, in 
fact, having undergone what I some time since ventured 
to call " reciprocal mimicry.^' I have elsewhere given more 
detailed reasons in support of this view ; I reintroduce it 
here for the sake of illustrating it from those Pierine marks 
that have been specially under consideration. t 

* JE.f/., (1) the abundance of some of the mimetic species of the 
same or of a closely allied genus, as Percute charops and Euterpe 
ti'.iras (testified to by Messrs. Godmau and Salvin and by Fritz 
j\I idler respectively) ; and (2) the fact that the nearest old-world 
representatives of the same group, i.e., the members of the genus 
Ih'Vias, have all the characteristics of insects protected by a 
disagreeable taste or odour. 

f It may perhaps be objected that the resemblance between such 
forms as are represented in Figs. 13, 14 is not sufficiently close 
to warrant the supposition of mutual protection between them. 
To this it may be replied, that (1) the colour of the diagonal band 
of the forewing is probably in the living IlcUconius much nearer 
to that of the Perente than appears in the figure, which was taken 
from a specimen that bad been for some years in the Hope collec- 
tion. It is well known that the reds in Hellconius and Acrcca are 
especially apt to fade on keepiug. (2) The resemblance may be 
enhanced by attitude, the figures having been di-awn without any 
particular attention to this. (.">) The brightly coloured basal marks, 
though occupying different relative positions in the two insects, 
convey the same general idea of a gently-curving, slender, white or 
yellow streak (belonging to the forewing in the Pereute and the 
Iriidwing in the Heliconlus), beset nearits base with isolated spots 
of vivid red, and traversing a black or dark-brown area of wing 
close to the body. 



Mimetic Patterns to the Original Form. 75 

The same argument will apply to features similar to 
the above which may be seen in certain Papilioninpe., 
Nymphaliufe, Erycinidie, and even in some moths. 
And I may say in passing- that Fritx Miiller's principle 
here referred to appears to me to be of much wider 
application than has been hitherto supposed. There 
exist several large groups more or less uniform in their 
scheme of coloration, though heterogeneous in their 
affinities, which it seems almost certain will in the main 
turn out to be cases of "inedible associations,'' each 
one possibly including a few instances of true mimicry 
within its borders. In deciding on the actual nature 
of such resemblances, it may be borne in mind that 
"reciprocal mimicry " constitutes good evidence of the 
distastefulness of all the forms between which it can be 
shown to occur, while the abundance or scarcity of a 
mimetic insect is also a valuable test of its edibilitv. 



IV. Divergent Members of an Inedible Group. 

The last set of figures (PI. V,, Figs. 1 5-1 8) discloses a re- 
markable state of things, which is of interest both in its 
bearing on what has been advanced in the preceding sec- 
tion, and also as providing a further illustration of the im- 
portance of small changes. The Pcvpilio represented in 
Fig. 15 (P. zacynthus ? ) is undoubtedly the model for the 
Pieiine shown in Fig. 16 (E. tereas). These two insects 
form one of Bates's original instances of mimicry. But 
beside the latter we have another Euterpe, viz., E. hellona 
(Fig. 17), whose markings are, without doubt, homologous 
with those of its congener. E. hellona however, though 
so closely resembling E. tereas the mimic of P. zacynthus, 
itself copies, not the Pajxilio, but the members of a group 
of Heliconius of which H. erato (Fig. 18) is a good 
example. The bright yellow patch on the forewing of 
the Heliconius is very well imitated by the Pierine, and 
on the hindwing of the latter the crimson patch of 
E. tereas, etc, has been modified into a series of scarlet 
stripes ; these being a palpable attempt to reproduce 
the radiating chestnut streaks of H. erato or one of its 
congeners. It is curious to see what slight modifications 
between the two species of Euterpe enable them to 



76 Dr. F. A. Dlxey oji the Relation of 

imitate two sucli distinct insects as the Papilio and the 
Helico7iiuK.^~ 

The addition of these two forms, viz., Enterpe heUona 
and Heliconius erato, the former of which was perhaps 
not known to Bates, evidently complicates the " mimicry " 
question. Is the resemblance between the Heliconius 
and the Papilio, which certainly exists though it is not 
very close, accidental ? But for the intermediate Pierine 
forms we should perhaps not have suspected any special 
relation between them. On the other hand, is the Heli- 
conius the general model for all the rest ? If so, 
P. zacyntlius becomes a mimic instead of a model ; whilo 
its own imitator, E. fereas, is in the curious position of 
mimicking a mimic, instead of going straight to the 
ibun tain-head, i.e., the Heliconius. 

In my opinion, the most satisfactory way of accounting 
for these complicated relations is the supposition that 
here we have another instance of a mimetic assemblage 
of the second kind — an ''inedible association." The 
two extreme forms, viz., the Papilio and the Heliconius, 
which by themselves might perhaps not be sufficiently 
near one another to be mutually protective to any very 
great extent, are held together, as it were, within the 
limits of an inedible mimetic group, by the welding power 
of the intermediate Eiiterpes.\ It is of interest in con- 
nection with what has been already advanced as to reci- 
procal mimicry, or the give-and-take system, in associa- 
tions of this kind, that the Papilio, the Heliconius and 
both Pierines are furnished on the underside with basal 
red spots. 



T. Conclusion. 

It cannot, I think, be doubted that the remarkable 
facts touched upon in the present paper raise points of 
fresh interest in the great question of mimicry. The 
leading and binding idea in all that I have said has been 

* The Heliconine pattern is still further developed in the female, 
and on the under sui'face of the male of E. bellona, than on the 
upper surface of the latter sex as represented in Fig. 17.

my conviction, formed after much deliberation, of the 
gradual and natural character of these complicated 
changes, and of the absence of any violent or arbitrary 
element in their process of development. Whether 
the explanations here suggested are true and adequate, 
can in most instances only be decided by observation in 
the field ; and it is much to be desired that travellers and 
residents in countries where these and similar phenomena 
occur should carefully record all facts relating to the 
habits, postures, modes and times of flight, prevalence, 
seasonal occurrence and exact distribution of the various 
species that come under their observation. 

There is also need of such experimental evidence as to 
the means of defence adopted by these forms as can only 
be satisfactorily obtained in the midst of their natural 
surroundings. Meanwhile, it must suffice to point out 
the conclusion towards which the only facts available 
appear to lead, while the actual verification by observa- 
tion and experiment must perforce be left to those whose 
opportunities enable them to apply these final tests to the 
subjects of enquiry. 

My best thanks are due to Prof. Poulton, F.R.S., for 
much encouragement and many facilities for work. The 
figures were drawn, by his permission, from specimens in 
the Hope Collection at Oxford.

IV. The Rhynchophorous Goleoptera of Japan. Part 
IV.* Otiorhynchidse and Sitonides, and a genus 
of doubtful position from the Kurile Islands. By 
David Sharp, M.A., M.B., F.R.S., etc. 

[Read February 5th, 1896.] 

Although the collections of Goleoptera made by Mr. 
Lewis in Japan are of great interest, and are the 
base of almost all that we know of the Bhynchophora 
of Japan, yet it is, I think, tolerably certain that as 
regards the GurcuUonidai proper — as distinguished from 
Anthrihidse, Scohjtidx, and Brenthidse — they are very 
incomplete, and I am inclined to believe that the 
Otiorhynchidie of Japan will prove to be twice or three 
times more numerous in species than the lists made from 
Mr, Lewis's collections will show. 

Under these circumstances it appears scarcely worth 
while to discuss the question of geographical distribution, 
particularly as our knowledge of the Rhynchophora of 
China, of Korea, of Mongolia, and the region round the 
mouth of the Amur, is very small indeed. I may, 
however, remark that the Japanese Otiorhynchldai have 
very little affinity with those of the European region. 
I here enumerate fifty- eight species belonging to twenty- 
six genera. Not one of the species is the same as an 
European one ; while of the twenty-six genera fifteen 
appear at present to be peculiar to Japan, and only five 
have representatives in Europe, and of these five it is 
tolerably certain that four will prove to be more charac- 
teristic of Eastern Asia than of the paleearctic region 
proper. The genus Otiorhynchiis is the most character- 
istic genus of the Mediterranean Curculionidous fauna, 
where it has altogether nearly six hundred species ; but it 
is not represented in Japan. Indeed, the only points that 
appear to give this section of the Japanese fauna any 
claim to connection with the European one is the 
existence of a considerable number of species of

Phyllohius in each, and the possession by Japan of 
a species of Scythropus allied to the European 
S. mustela. 

I very much regret the delay that has occurred in the 
preparation of this paper, which was commenced several 
years since ; and also that I shall not be able to continue 
the work for some time to come. But I hope that 
Mr. Lewis, who besides forming his splendid collection, 
has himself done so much towards working out the 
insects he procured, may be able to complete our know- 
ledge of the Curculionidse. 



OTIORHYNCHID^. 

This term I use in the sense of Leconte and Horn, 
classification of Col. of N. America, 1883. It is very 
different fi'om the Otiorhynchides of Lacordaire. I have, 
however, admitted an exception in the case of the genus 
Meotiorhy iichus, which does not possess the scars on the 
mandibles, that is the special character of the family 
OtiorhyncJiid^e, accordiug to the American taxonomists. 
I adopt two divisions, Otiorhynchidie apterx and 0. 
alaf^e, which, practically, are almost equivalent respec- 
tively to the Divisions I. and IT. of the N. American 
writers, as explained in the Biol. Centr. Amer., Col. IV., 
pt. 3, p. 87. 



OTIORHYNCHID^ APTER^. 

This division was not recognized as distinct from the 
winged forms by Lacordaire, consequently its members 
were distributed throughout the Brachy derides and 
Otiorhynchides of the Belgian naturalist in so complex 
a manner as to render the application of his nomen- 
clature to the divisions proposed by Leconte and Horn 
almost impossible. At the same time I do not know 
enough of the forms dealt with by the American 
naturalists to enable me to judge whether the Japanese 
wingless Otiorhynchidae would enter satisfactorily into 
their divisions, and I therefore adopt the plan of 
arranging the sixteen genera that have been discovered 
in Japan in the following manner : — 



Rhynchophorons Coleopfera of Japan. 83 

1. Thorax with ocular lobes. Group I. Ophryast'ma ; Pseudoaieo- 

rhinus and Calomycterus. 
V. Thorax without ocular lobes. 

2. Scrobes lateral, elongate, directed inferiorly, so that their 
lower margin passes to the under edge of the ros- 
trum without being directed towards the eye.

p. 10. 

The position this genus should occupy is in the 
Ophryastina, where it will form a division separated from 
the American forms by the connate claws. Mr. Roelofs 
first placed it in the Leptoptsides, of which the Ophry- 
astina formed, according to Lacordaire, a separate 
division. With Trachyphlceus the genus has but little 
affinity, as it possesses well-marked ocular lobes, connate 
claws, and very deep scrobes.

enc. Belg., xxii., p. liii, and Ann. ent. Belg.,

This is distinguished from its congeners by the very 

rotund form of the elytra, which are almost circular 

in their outline ; the antennae are very short ; and 

the upright setee on the elytra are fine, short, and 

minute.

2. Pseudocneorrhiniis ohesus, Roelofs, Ann. ent. Belg., 

xvi., p. 177, pi. iii., fig. 10, and xxiv., p. 11. 

The individuals of this species are the largest of the 
genus ; the elytra are broad and very convex, and in out- 
line are intermediate between P. hifasciatus and setosus ; 
the erect set£e are much larger than in P. hifasciatus. 

P. ohesus appears to be scarce, but altogether Mr. Lewis 
has obtained ten specimens ; the only localities I can record 
for it are Kiga and Miyanoshita, on the Main island. 

3. Pseudocneorrhinus setosus^ Roelofs, C.R. ent. Belg., 

xxii., p. liii., and Ann. ent. Belg., xxiv., p. 12. 

Closely allied to P. ohesus, but rather smaller and 
considerably narrower, and with the erect scales on 
the elytra broader than in either of the congeners. 

Kiushiu and Main islands ; Ichiuchi. 

4. Pseudocneorrhiniis minimus, Roelofs, C.R. ent. Belg., 

xxii., p. liii., and Ann. ent. Belg., xxiv., p. 13. 
This comes near to P. ohesus, but the individuals 
of that species are the largest, those of P. minimus the 
smallest, of the genus : besides this, the antennae are 
considerably shorter in P. minimus. 

Roelofs described the species from two specimens 
ound by Mr. Hiller. In his recent journey Mr. Lewis 
captured four examples.

Bhynchophorous Coleoptera of Japan. 85 

About twenty examples of this species were found at 
Hakodate : most of them agree with M. Roelofs^ descrip- 
tions satisfactorily ; but five of them belong to a well- 
marked variety, in which the upper surface is almost 
uniform pallid grey, the maculation of the elytra and 
thorax being nearly absent. Scarcely any two specimens 
of the type-form agree exactly in the maculation. 

2. Copanopachys griseus. 

Piazomias griseus, Roelofs, op. cit., xvi., 1873, p. 162 ; 
G. griseus, id., xxiv., p. 8. 

I have before me about a score of examples that I 
refer to this species, though they vary enormously 
in colour, greatly in size, and somewhat in minute 
structural characters. All, however, differ from C. 
tigrinus, in having the eyes more convex, and the front 
tibige not in the least dilated externally at the apex. 
One of them in colour exactly resembles the typical form 
of G. tigrinus, while on the other hand, the smaller 
examples are wonderfully like Scepticus insularis. 

Main island; Enoshima, Kawatchi, Yokohama (in April), 
Kobe. One specimen from each locality. The others 
were all obtained during Mr . Lewis's earlier visits, and 
the localities have not been preserved, but, no doubt, all 
are from the islands south of Yezo, while 0. tigrinus is — 
so far as we know at present — confined to that island.

both internally and externally by very short thick spines ; third 
joint of tarsus normally lobed and densely pubescent beneath. 
Claws moderate, free. 

This genus is a most anomalous one, and in the 
present condition of the classification of the CurcuUonida}, 
its position must remain an open question ; it could be 
placed quite satisfactorily in the Otiorhynchidai were it 
not that no mandibular scar exists : the mandibles, 
indeed, are so formed at the apex, that no deciduous 
pieces could be seated on them ; while their sharp front 
and prominent angles, may perhaps be found to be 
a functional substitute for the deciduous pieces. This 
structure of the mandibles, added to that of the tips of 
the hind tibiae, distinguishes the genus satisfactorily from 
Copano'pachys, which is unquestionably its nearest ally ; 
the two genera possessing a great similarity of facies. 

1. Meotiorhynchiis querendus. 

Elougato-ovalis, niger, fusco-griseo-squamosus, limbo irregu- 
lariter pallido ; opacus. Long, 10-10 j mm. 

Rostrum short and broad, rugose in front, with a deep channel 
on the middle ; eyes moderately prominent ; antenna) short and 
stout. Thorax rather long, curvate at the sides, obsoletely sculptured, 
covered with very small sordid scales, with an obscure channel on 
the middle. Elytra elongate, quite narrow at the base, where, 
however, they just exceed the width of the base of the thorax, 
thence becoming broader for about one-fourth or one-fifth of the 
length ; acuminate at the apex, finely striate, covered with minute 
scales, which are of an almost viniform dark colour, except at the 
sides where they become more or less pallid, though in a very 
variable manner. Legs stout ; apex of hind tibite very large. 

Mr. Lewis procured a small series of this very 
interesting insect at Hakodate, in Yezo. One of the 
specimens is a very beautiful variety in which the upper 
surface is maculate, somewhat as in Copanopachys tigrinus, 
with numerous pallid marks, the scales that are almost 
uniformly dark in the typical form, being, moreover, 
metallic. This example is a little smaller than the 
others, and slightly different in outline, so that it may 
possibly prove to be of a distinct species.

I enter this in the Japan list, solely on the authority of 
M. Roelofs, who says of it, " Tres commun an Japon." 
There are, however, no examples of it in the Lewis 
collection. Indeed, I have not yet seen any Chinese 
example of the genus that agrees with the Japanese 
exponents, and Chevrolat described the species from 
China. 

2. Piazomias lewisii, Roel. 

Piazomias lewisi, Roelofs, Ann. Soc. ent. Belgique,

This species was not described in M. Roelofs' first 
paper on Japanese Rhynchophora, and 1 think it possible 
that it was this insect he alluded to in his first paper, 
under the name of P. velatus : in which case, the latter 
name should be withdrawn from the Japanese cata- 
logue. 

According to Mr. Lewis's collection, this is by no 
means a prominent insect in the Japanese Coleopterous 
fauna ; he found a few specimens in the island Kiushiu, 
in April, and one at Kobe, on the south coast of the 
Main island.

A few specimens only have been obtained of this 
species. It is apparently very variable, but the material 
does not enable me to decide certainly that there is 
more than one species. Two individuals (without exact 
locality) have the elytra longer, and narrower, of a very 
dark colour, and marked behind the middle with two 
separated spots instead of a fascia. 

Kiushiu, at Nagasaki and Ichiuchi in April. 

Blosyrus, Schonherr. 
1. Blosyrus japoniciis, n. sp. 

Niger, fusco-squamosus, sordidus, antennis piceis, prothorace 
brevi, medio carinulato, elytris globosis, interstitiis leviter convexis. 
Long. 6^ mm. 

Antenna) short, third joint scarcely longer than the second. 
Rostrum very short, not longer than broad, flat, with distinct 
angular transverse depression in front of the eyes. Thorax 
short and broad, very strongly transverse, rounded at the 
sides, with an obscure carina on the middle, most distinct in front ; 
the surface squamose ; with a few very minute shining granules. 
Elytra much broader than the thorax, convex and globose, with 
series of rather coarse punctures, the interstices broad, slightly 
convex, and set with very short set*. 

The sculpture and clothing in this insect are more or 
less obscured by the dirt with which the insect becomes 
covered. There is a longitudinal channel on the middle 
of the head in two examples ; in two others it can 
scarcely be detected, perhaps owing to its being 
obliterated by dirt mixed with an exudation. 

Awomori and Sapporo : four specimens. 

Catafionus. 

Catapionus, Schonh., Gen. Cure, vi., 2, p. 245 ; Roelofs, 
Ann. ent. Belg., xvi., p. 155. 

M. Roelofs has examined the type species of this 
genus, and has informed us that the G. viridimetaUicus 
of Japan is certainly congeneric with it. He has also 
called attention to some errors in Lacordaire's description 
of the genus, and has added three other species from 
Japan : I should certainly not have recognized Lacor- 
daire's description of the genus as being applicable to 



Rhynchophorous Coleoptera of Japan. 89 

these Japanese insects, had it not been for M. Roelofs' 
investigation. The genus is very closely allied to 
Ctieorhinus, whereas Lacordaire places it in the Bary- 
notides ; but, as 1 see no reason to doubt the correctness 
of the conclusion M. Roelofs arrived at, I accept it ; as 
also his decision that the other species he describes, as 
belonging to the genus should really be placed in it. 
The Gneorhinus ? nodosus, Motsch., was not known 
to M. Roelofs, but it has been obtained by Mr. Lewis 
during his recent journey, and should, I think, also 
be associated with the other species of Catapionus 
at present. Although very different in appearance and 
in several details of its structure from the C. viridi- 
metallicus, it is approached in so many points by C. 
clathratus, Roel., that I hesitate to make it a new 
genuo.

Nikko, Subashiri, Miyanoshita. 

The species has been received by Mr. J. H. Leech 
from China (Kiu-Kiang and Ichang), and I have 
an individual in my collection labelled as being from 
Assam. 

C. nodosus has the rostrum broader at the apex, 
and more angularly prominent on each side, the man- 
dibles are shorter, and each elytron is strongly lobed at 
the base. Harold's subsequent reference of this insect 
to Dermatodes was certainly erroneous. 

2. Catapionus clathratus, Roel. 

Catapionus clathratus, Roelofs, op. cit., xvi., 1873, 
p. 157. 

This was described from a single specimen. In 1881 
Mr. Lewis procured a small series of examples at 
Nagasaki, Kashiwagi, and Otsu, in the months of June 
and July. There is very little variation amongst 
them, though the species has been found in two of the 
islands.

Catapionus modestus, Eoelofs, t. c, p. 156. 

This is at present the rarest species of the geaus. 
I have before me three examples found at Nikko and 
Shimonosuwa, on the Main island. 

4. Catapionus ohscurus, n. sp. 

Xiger, griseo-squamosus, plus minusve obscure fusco-varie- 
gatus ; prothorace rugoso, medio obsolete sulcato ; elytris inter- 
stitiis alternis paululum magis elevatis. Long, cumque rostro, 
7-9 mm. 

This is closely allied to C. gracilicGrnis, Eoelofs, but is 
much smaller, and has shorter antennae, with the third 
joint only about half as long. The rostrum is nearly 
parallel-sided, a little broader in front : the third joint of 
the antennas is a little longer than the second ; the club 
is black, in marked contrast to the other parts : the 
rostrum has, on the upper part, an indistinct lateral 
groove on each side, in addition to the vagae median 
depression. The thorax is narrower in front than at the 
base, but little rounded at the sides, the base nearly 
truncate. Elytra with rounded shoulders and fine serial 
punctures. 

Found during the month of August, 1881, at several 
localities in the centre of the Main island : seventeen 
examples. 

5. Catapionus gracilicomis, Roel. 

Catapionus gracilicomis, Roelofs, op. cit., xvi., 1873,

in the northern parts of the Archipelago.

Rhynchophorous Coleoptera of Japan. 91 

Teachyrhinus, geu. nov. 

Corpus rugosum, sordidum, sat elongatum, setis erectis parce 
vestitum. Scrobfe laterales, latse. AntenuEe scapo sat elongate 
setoso, apicem versus crassse. 

Distinguished from Tro.chyphloeosoma by the more elongate 
rostrum, with longer scrobes. and by the comparatively elongate 
form of the body. The mandibular scars are distinct, the scrobes 
are very broad, owing to the arching of their upper margin, which 
causes them to encroach a little on the upper face of the rostrum, 
but the general direction and position of the scrobes is that of the 
Brachyderides, rather than that of the Otiorhynchides : there are 
no ocular lobes or vibrisste, the eyes are rather small, nearly cir- 
cular not prominent. The nasal plate is extruded so as to form an 
abrupt prominence. Femora not dentate : claws small, not 
connate. Metasternum very short : second and third abdominal 
sutures extremely deep ; second segment equal in length to the 
part of the first segment that lies behind the coxas. Tarsi rather 
small : tips of hind tibiaj slender, minutely mucronate. 

This insect has somewhat the facies of Trachyphloeus. 
It may be described as a connecting link between 
Amystax and T r achy phhco soma. It differs from the 
former by the scrobes which are broader, attain the eye, 
and are somewhat visible from above. The abrupt 
prominence of the nasal plate is peculiar. 

1. TrachyrJdnus sordidus, n. sp. 

Piceus, suboblongus, rugose sculpturatus, setosus, parcius 
obscureque squamosus ; prothorace sat elongato, medio canali- 
culato. Long, 5, lat. 1| mm. 

Antennce obscure red, scape rather long, with very distinct erect 
set« on the lower margin, 2nd joint rather long, 3rd a little shorter, 
4-8 differing but little in length, the 8th slightly broader than the 
preceding, about as long as broad ; club oval, moderately long 
and stout. Nasal plate small but peculiarly prominent, placed 
entirely in front of the antennal insertions : front of rostrum 
rather broad, rugose ; eyes entirely lateral, rather distant from the 
thorax. Thorax nearly as long as broad, slightly narrower than the 
elytra, curved at the sides and a little narrowed behind, coarsely 
and very deeply rugose. Elytra rather narrow, very little narrowed 
in front, very coarsely sculptured, but covered with an exudation 
mixed with dirt, which obscures also the small scales ; the erect 
setaj very distinct, slightly clavate. In the male there is a deep 



92 Mr. David Sharp on the 

oblong impression on the metasternum and first abdominal seg- 
ment : the apical ventral segment is prominent, and broadly 
but vaguely impressed. The female is of less elongate form, and 
has the breast unimpressed.

I can find very little to distinguish as species the St. 

Helena Trachyphlaiosoma setosum, Woll., from the 

Japanese Trachyphlceops setosus, Roel., and as genera I 

can see no distinctions. It therefore becoraes necessary 

to change the name of the latter species as being later. 

The genus has only a superficial resemblance with 

Trachijphlaeus, next to which it is usually placed.

Lagostomus turritus, Schonh., Gen. Cure, i., p. 613;

This species has been, after several misconceptions as 
to its position, referred to Episomus. It may be pro- 
bably separated as a distinct genus (with E. mundus), 
but this may be left undecided at present. 

E. turritus appears to be a common insect in China, 
and is probably not rare in the Southern parts of Japan. 
One of Mr. Lewis's specimens is labelled *' found only on 
Aralia maximowiczi." It is a very variable insect in 
colour, size, and, to a less extent in sculpture. I have it 
from various localities in China, including Kiu Kiang 
(Pratt) and Shanghai.

2. Episomus mundus, n. sp. 

Squamosus, subtus cretaceo-albidus, supra fuscus, utrinque late 
albido-plagiatus, apiceque albido, antennarum apice nigro ; supra 
vage sculpturatus, hand tuberculatus. Long. 14 mm. 

Slightly smaller than E. turritus, with more slender 
limbs, and at once distinguishable by the absence of 
tubercles on the elytra. The surface is very densely 
covered with extremely minute scales, and the system of 
coloration is more like that of E. turritus than of other 
species of the genus. There is a single very deep groove 
along the middle of the rostrum, but no lateral rugce. 
The thorax has no transverse folds or grooves, and it is 
only obsoletely and sparingly rugose, but there is a 
broad longitudinal impression along the middle con- 
sisting of two parts separated on the disc. The elytra 
seen in profile, ai"e at first flat or nearly so, but then rise 
greatly so as to be very convex ; they are sculpture with 
series of irregular, large, not deep pits, separated only 
by quite small interstices. A single specimen only has 
been found of this elegant insect, it does not appear to 
be related to any species but E. turritus.

Myosides, Roelofs, Ann. Soc. ent. Belgique, xvi., 1873,

This genus comes near to Coenopsis, from which it is 
distinguished by the larger interval between the eye 
and the scrobe, the former being placed also nearer to 
the thorax. 

1. Myosides seriehispidus, Roelofs, Ann. Soc. ent.

Miyanoshita in April. 

2. Myosides pyrus, n. sp. 
Dense fusco-squamosus, subpyriformis, setis erectis tenuibus

94 Mr. David Sharp on the 

Antenna3 piceous, with elongate scape. Rostrum moderately 
long, very densely squamose except on the very definite angular 
space that limits the nasal plate ; the tip very distinctly bi'oader. 
Eyes round, slightly prominent. Thorax short, not much more 
than half as broad as the elytra, densely squamose, but with 
minute seta3 placed i ii punctures that are concealed by the squa- 
mosity. Elytra narrow at the base, but becoming much broader 
behind, convex, finely striate, very densely squamose, with erect, 
moderately long, slender setae. Legs piceous, moderately long, 
setose and feebly squamose. 

This little weevil somewhat resembles Episomus in its 
general form. By the expanded tip of the rostrum it 
differs considerably from M. seriehispidus , and ap- 
proaches Peritelus. Probably a distinct genus should 
be established on it. The claws are not connate. 

A single individual was met with at Nikko, Main 
island, in June. 

Arrhaphogastee. 

Arrhaphogaster, Eoelofs, Ann. Soc. ent. Belgique, xvi., 
1873, p. 163. 

The affinity of this genus appears to be with Phlyctinus. 
It differs from Celeuthetes by the scrobes being anterior 
instead of lateral. From Phlyctinus it is distinguished 
by the scrobes being foveiform instead of linear. The 
claws are not connate. The scar of the mandible is 
not very large, but is distinct on the left side, less so 
on the right one.

AsPHALMUS, gen. n. 

Antennae, anteriores, scapo sat elongate. Rostrum brevissimum, 
haudpterygiatum. Femora dentata. Corpus setis tenuibus depressis 
vestitum. 

The insect for which I propose this new genus is 
similar in appearance to the European Omias hohemanni, 
from which it is distinguished by the scrobes whose 



Bhynclioplioruus Cohoptera of Jajmu. 95 

posterior part encroaches on the front of the rostrum, so 
that they are separated only by a prominent^ somewhat 
narrow, space ; by the dentate femora and by the body 
being clothed with depressed instead of erect seto3. 
From Arrliaijliogaster it is distinguished by the smaller 
interval separating the scrobes above and by the 
dentate femora. The eyes are quite small, but rather 
prominent, and are placed far in front of the thorax. 
The latter is without trace of vibrissfB or ocular lobes. 
The presternum is only about half as long as the notum, 
the cox£e being placed almost at its front margin. The 
metasternum is extremely short ; the hind coxre are very 
widely separated. The abdominal sutures are moderately 
deep. The tips of the hind tarsi are very slender. The 
claws are small, equal, connate. These characters bring 
the genus somewhat near to Peritelus, though the two 
are not all similar. The Japanese insect is distinguished 
by the form of the rostrum and scrobes, and the hair-like 
clothing of the body. 

1. Asphalviiis japonicus, n. sp. 

Fusco-rufus, pube grisea depressa, parce vestitus ; prothorace 
densissime, ruguloso-punctato ; elytris profunde crenato-striatis, 
interstitiis convexis. Long. 4, lat. 2 mm. 

Rostrum very short, eyes placed almost half-way between the 
front of the thorax and the base of the antennae. Scape moderately 
long, sub-curvate, thickened from base to tip. Head densely punc- 
tured, sub-foveolate above the eyes. Thorax very densely, not 
coarsely rugose-punctate. Elytra convex, ovate, much broader than 
the thorax, with rather broad and deep crenate striie, the interstices 
convex, and furnished with depressed pallid hairs. Ventral 
segments shining, with only distant and rather fine punctuation. 
Tooth of front femora quite distinct, of the hind almost 
imperceptible. 

Of this distinct insect eight specimens were met with 
on the Main island at Shiba in Tokio, in May, 1880. 

Oraoiotus, n. gen. 

Ex affinitate generis Otiorhynchi. Corpus parvum fere nudum.

apicibus nullo modo dilatatis. 



96 Mr. David Sharp on the 

The small weevil for which I establish this genus, has 
the facies of an Omias, such as 0. concinnus, but it 
appears to be more closely allied to Otiorhynchus, 
of which it might form a sub-genus, were it not that the 
scrobes of the antennge in their upper part encroach more 
on the front of the rostrum, and are consequently less 
widely separated than in Otiorhynchus. 

AntennEe moderately long, scape slender at the base, much 
thicker at the apex, extending beyond the front margin of the 
thorax. The rostrum short, thicker at the apex, distinctly 
pterygiate, the true scrobes quite short and convergent, but the 
rostrum above them excavated, so that the front of the rostrum is 
in the middle comparatively narrow. Eyes small, very convex. 
Front coxiB almost imperceptibly separated. Mentum with 
a short peduncle, and not filling the buccal cavity. Mandibular 
scars small but distinct. Third and fourth ventral segments 
not very short. Front femur with a large tooth, middle and 
hinder with smaller teeth. TibiiB slender at tips, the posterior 
with two excessively minute spurs at the lower angle. 

1. Omoiotus ovatus. 

Gracilis, testaceus, capite thoraceque dense punctatis, illo inter 
oculos foveolato; thorace elongate, elytris multo angustiore ; his 
f ortiter, regulariter, seriatim punctatis, interstitiis leviter convexis. 
Long. 4 mm. 

Second and third joints of antennre rather elongate, the 
latter a little the longer, slender. Rostrum and head very 
densely punctate, the former short, but little longer than broad, 
without nasal plate, with a small deep fovea between the eyes ; 
these remote from the thorax, very prominent. Thorax rather 
long and narrow, slightly longer than broad, curved at the sides, a 
little broader at the base than in front ; densely i-ather coarsely 
punctate, rugose at the sides but not along the middle. Elytra 
rather slender, ovate, the series of punctures remarkably regular, 
each puncture rather large, the interval between each and the next 
very small : the interstices extremely regular, and bearing some 
minute depressed hairs ; the series of punctures are ten, the outer 
one being placed very near to the margin, and obsolete behind. 
Ventral segments shining, almost smooth. 

Two specimens were found, but the exact locality has 
not been recorded. This little insect is of considerable 
interest owing to its great approximation to the European 



Rhynchophoroiis Coleoptera of Japan. 07 

genus Otiorliynchuis. It is^ in fact, all that has been 
discovered in Japan to represent the great genus that 
has several hundred species in Europe. 

OTIORHYNCHID^ ALAT^. 

The Japanese species of this division are not very 
numerous, but it is probable that a good many others 
remain to be discovered. 

There is but little difficulty in distinguishing- the 
genera. These are eleven in number, and may be 
tabulated as follows : — 

Prothorax without ocular lobes or vibrisste. 
Claws connate. 

Scrobes visible from front. 

Rostrum with prolonged front angles . . Diallohius. 
„ simple, as usual at tip .... Phyllohius. 

Scrobes entirely lateral Scythropus. 

Claws free. 

Scrobes widely separated. 

Antennae longer than the body .... EumyUocerus. 
Antennse not longer than the body. 

Second joint of antenna? short . . . Macrocorynus. 
„ ,, „ long .... Myllocerus. 

Scrobes separated on upper surface by only 
a small space. 
Rostrum with a recurved process at tip . Anosiinus. 
„ without ,, ., „ . Hyperstylus. 

Prothorax with vibrissas or ocular lobes. 

Prothorax Vith vibrissse but not lobes . . . Chlorophamts . 
„ without vibrissas, but with lobes. 

Rostrum rather slender, broader at tip . . Phytoscaphus. 
„ thick, not broader at tip .... Canoixus. 

Phyllobius, Germar et Auct. 

The Japanese species of this genus appear to be 
numerous, and I have no doubt others will have to be 
added to those here mentioned. 

The species are far from being closely allied to those 
found in Europe, though the existence of the genus 
in Europe and Japan, and its representation in each of 
the two provinces by numerous species, is the chief 
character that could be cited as evidence of an affinity 
between the Otiorhynchid ftiunaD of Europe and Japan.

The male of the insect I identify as tliis species, has 
the trouf^h, or gouge-shaped depression, on the terminal 
ventral plate very deep, and the preceding two segments 
are more or less deeply, broadly impressed; the first 
abdominal segment is only shghtly impressed on the 
middle, and the metasternum has no angular prominence 
on either side of the median impression. The front 
tibia) have only a slight sinuation of the inner margin 
below the middle ; the hind tibise have a very feeble 
concavity of the inner face of the apical part. The head 
has only a slight swelling of the surface posterior to the 
eyes. The antennae are very long ; the upper surface of 
the insect is rather densely covered with minute green 
scales, and there is no long pubescence. 

M. Roelofs did not at first distinguish between this 
species and P. lyrolonrjatus, and most of his specimens 
in the Lewis collection belong to the latter species. 
Altogether I have examined eight specimens of P. longi- 
rorui.s : the localities are Nikko, Yokohama, Oyama, and 
>\livanoshita, on the Main island; Hakodate inYezo. 



2. P/tijIIohius prolongatus:

I accept, as representative of this species, an individual 
in Mr. Lewises collection, determined by one of the 
German authorities who examined Herr Killer's Japanese 
Coleoptera. 

P. prolongatus is closely allied to P. longicornis, and 
is densely covered with golden-green scales, but has 
the male characters much less remarkably developed, 
the depression of the last ventral plate being com- 
paratively slight, and the preceding two segments being 
simple; the tooth of the front femur is considerably 
smaller, and all the femora are less swollen. In the 
female the ventral segments are more bare than they are 
in P. lungicornis.

vary a good deal in colour and in the vestiture. Most of 
the series were procured at Nikko, but the species was 
also met with at Miyanoshita, Higo, Bukenji, Oyaraa^ and 
Awomori. 

3. Phyllohiiis armatus. 

P. armatus, Roelofs, Ann. Soc. ent. Belgique, xviii., 
C.R., p. cxxviii. 

This species was described by M. Roelofs from a single 
pair, found by M. Van Volxem, and was not represented 
in the first collection made by Mr. Lewis, I refer to the 
species six examples found by Mr. Lewis at Nikko, 
Tokio, and Oyama. The insect is rather more robust, 
and has a broader after-body than its allies, and is 
distinguished, in addition to the remarkable characters 
of the male, by the conspicuous, soft, upright pubescence 
with which the body is clothed. In addition to the 
remarkable structure of the male front tibia3, described 
by M. Roelofs, it should be noticed that the hind tibia3 
have a slight excavation on the apical portion of the 
inner face, that the metasternum and first abdominal 
segment are impressed, but that the apical ventral 
segment is not trough-like, but vaguely irregularly 
impressed. It is not noticed in M. Roelofs' description 
that the antennte are in larger part black, and that there 
is a vague, denuded black stripe, along the side of each 
wing-case. 

4. PJiyllohius annectens, n. sp. 

Gracilis, niger, viridi-squamulatus, pube laxa, erecta, minus dense 
vestitus ; antennis elongatis, tenuibus, ex parte rufis. Long. 8-9 mm. 

This is allied to P. armatus, and is distinguished from 
other species, except the one mentioned, by the erect, 
soft pubescence clothing the body. The front tibiee of 
the male are like those of P. armatus, but are more 
slender; while on the ether hand the hind tibias are 
more evidently dilated at the tip, and more deeply 
emarginate on the inner face. 'L'he abdominal characters 
of the male are like those of P. armatus, but the apical 
ventral plate is more regularly depressed in a longitudinal 



100 . Mr. David Sharp on the 

manner along the middle. I'he female may be distin- 
guished from the same sex of P. arinatiis by the narrower 
form, the absence of a denuded stripe on the side of the 
wing-case, while in general appearance it is intermediate 
between the species named and P. lo)igicorms. 
Nikko and Kashiwagi, in June. 

5. Phyllobius rotundicolUs. 

P. rohindicollis, Roelofs, Ann. Soc. ent. Belgique, xvi., 
p. 167. 

This remarkable species is distinguished by the pecu- 
liar ashy or cinereous clothing of the upper surface, which 
has a more or less indistinct metalhc shimmer, but is 
entirely absent from a broad stripe on the side of the 
wing-case : the clothing is more like hair than scales. 
The eyes are very convex^ and the head above them is 
much ssvoUen. There is great difference between the 
sexes. The apical ventral segment of the male is 
broadly and deeply impressed, and the segments in front 
of it are also more or less impressed, as well as the hind 
part of the metasternum. The teeth on the femora are 
elongate and spiniform. 

P. rotundicollis is apparently a rare insect, and has 
only been met with at Nagasaki. It occurs in early 
spring: Aprill2th, 1881. 

6. Phyllobius nigritus, n. sp. 

Nigricans, hand squamosus, pube tenuissima erecta parce 
vestitus, pedibus antennisque rufo-obscuris, his tenuibus, per- 
elongatis. Long. 7 mm. 

This species differs from the other Japanese Phyllobii 
hitherto brought to light by the absence of scales or 
coloured hairs, resembling in this respect the European 
P. ohlongus, to which, however, it is, in other respects, 
but little allied. The antennae are as slender as those of 
any species I have seen of the genus, and are also very 
long; the club is particularly slender, and is acuminate. 
Head coarsely rugose, inflated above the eyes, depressed 
between these, which are very convex. Thorax very 
densely rugose-punctate, opaque. Elytra with very 
regular series of punctures, the interstices slightly con- 



Rhynchophurous Coleoptera of Japan. 101 

vex ; the very fine hair is quite short in front, but on the 
apical part is longer and more conspicuous. The femora 
are each armed with a remarkably prominent tooth, that 
On the middle and hind femora being more abrupt and 
spine-like than usual. 

The male differs much from the female, being of more 
long and slender form, with the antennse somewhat 
longer and the femora more inflated. The breast and 
the first ventral plate are depi-essed in the middle, and 
the terminal ventral segment is broadly, rather deeply im- 
pressed ; there are slight depressions on the penultimate 
and antepenultimate segments. 

Hitoyoshi in Kiushiu, May 8th, 1881 : a small series. 

[Phyllohius picipes.] 

P. picipes, Motsch., Etudes ent. ix., p. 20 (1860) ; 
Desbrochers, Abeille, xi., 1873, p. 660. 

Motschoulsky's description is of little importance, but 
he remarks that the species is 4-5 mm. long, that it 
resembles P. argentatus, and that the eyes are *^sub- 
prominuli.'^ Desbrochers' description was made from a 
specimen sent by Motschoulsky to Jekel ; and of this 
Desbrochers says that the eyes are " tres-saillants, tres- 
detaches.^' This renders it clear that Motschoulsky 
mixed together at least two very distinct species — the 
prominence of the eyes being of very great importance 
in the Japanese Phyllobii — and 1 think his name should 
be consigned to oblivion. 

7. Phyllobius japonicus. 
Minor, niger, sat dense viridi-squamosus, pedibus antennisque 
rufo-obscuiis, his clava nigra. Long. 5 mm. 

t Phyllobius japonicus, Faust, Stett. ent. Zeit. 1., 1889, 
p. 221. 

Distinguished from the other species by smaller size, 
and by stouter, less elongate antennse, as well as by the 
almost total absence of external sexual distinctions. The 
clothing consists of minute, brilliant green scales, which, 
however, are nob closely placed, and of short pubescence, 
which is fine and not erect, and therefore inconspicuous. 
The eyes, though strongly prominent, are not so much 
80 as in the various preceding species. The form of the 



102 Mr. David Sliarp on the 

rostrum and scrobes is that of P. calcaratus. The scape 
is strongly bent, moderately long and stout, the club 
rather short ; there is no swelling over the eyes. The 
thorax is small, much narrower than the elytra, nearly 
straight at the sides. The elytra are rather long and 
narrow, and have no denuded lateral stripe. All the 
femora are dentate, the tooth being rather broad and 
short; the hind tibias are somewhat cut away on inner 
face of their lower half, and this part is minutely ci'enate 
or tuberoulate. 

Kashiwagi, in the southern part of the Main island, 
June 20th, 1881 : a small series. 

Two females have no metallic coloration, the elytra 
being covered with a fine pubescence somewhat as is 
P. nigritus. I consider them to be only a variety of 
P. japonicus. 

P. japonicus was described by Faust from a single 
example, said to be of the female sex. It is not quite 
clear from the description that it is certainly this species, 
but I cannot reconcile Faust's description with any other, 
except this species. 

8. PhyUohius polydrusoides, n. sp. 

Squamulis Isete viridi-micantibua dense vestitus ; antennis 
scapo in medio abrupte curvato, fere angulato. Long. 5 mm. 

This is a very remarkable species, of which only one 
example has been found. It has the appearance of a 
Polydrusns more than of a PhyUohius, and the head has 
a marked angular prominence on each side over the eyes, 
much the same as in Pohjdrusus pterygOmalis. The scape 
is short, nearly black, just before the middle abruptly 
bent, the outer part incrassate, the club short, and not 
acuminate. Eostrum very short, the scrobes not definite, 
but attaining the eye ; this latter convex very remote 
from the thorax, the front of the rostrum quite flat. 
Thorax rather small and short, brilliantly scaled. Elytra 
covered with scales of a beautiful green colour, without 
any admixture of pubescence, the series of punctures quite 
distinct, the external one deeply impressed at the tip, 
and broader, so as to mark off there a sort of inferior 
margin. Legs black, clothed with some setae, tarsi 
piceous. Femora each armed with a slender tooth, that 
on the anterior being minute. 



Rhynchophorous Coleoptera of Japan. 103 

This species might be separated as a distinct genus. A 
single example only was found at Kashiwagi^ June ] 9th, 
1881. 



9. Phyllohins incomptns, n. sp. 

Dense griseo-squamosus, iii elytris maculis obscuris indistinct is 
subvariegatus, antennis rufis ; femoribus vix incrassatis, dente 
minuto armatis. Long. 5h-G mm. 

This appears to be somewhat allied to P. pomonx, 
though of a different colour and with a longer rostrum. 
The upper surface is densely covered with adpressed 
scales, without any mixture of pubescence : the scales 
are of a very pallid grey colour, and on the elytra are 
very faintly mottled by some irregularly distributed 
darker patches. The antennae are unicolorous, pale red. 
The thorax is short only slightly curved at the sides, and 
a little narrowed towards the front. The elytra are 
rather long, become distinctly broader behind, and 
notwithstanding their dense clothing of scales have very 
evident punctate-strite. The under surface is densely 
squamose. The legs are pale red, but much clothed 
with scales and seta3, there is a distinct tooth on the 
middle and posterior femora. I do not see any sexual 
differences. 

Miyanoshita. 



10, PhyJlohius leecJii, n. sp. 

Dense griseo-squamosus, hand variegatus, antennis rufis ; 
femoribus in medio leviter incrassatis, ncc angulatis, nee dentatis. 
Long. 5 mm. 

This is extremely closely allied to P. incomphis, but 
must be separated on account of the unarmed femora, 

I have a single specimen from the late Mr, Fryer's 
collection, given me by J. H. Leech, Esq., and there is a 
specimen in Mr. Lewis' series of Phyllohms found by 
him at Kashiwagi on 16th June, 1881. The specimen 
from Mr. Fryer's collection has the antennae considerably 
shorter than they are in P. incomptus, or in the example 
of P. leechi from Kashiwagi. 



104 Mr. David tSharp on the 

DiALLOBirs, n. gen. 

Generis Phyllobii proxime affinis. Rostrum apice lato, ptery- 
giatum, angulis anterioribus acutis, breviter recurvatis. 

This genus has the facies of the densely scaled specips 
of Pliyllohius — P. pomonpe — e.g., but the peculiar 
dilatation of the apical part of the rostrum, by which the 
scrobes are made anterior and entirely exposed in front, 
is diagnostic. The structure of the parts of the mouth 
appears to be much the same as that of Phyllohins, the 
mentum is, however, rather less slender, so that the 
maxilloB are not exposed ; the minute labial palpi are, 
however, seated on the front of the mentum and quite free. 
There is no trace of either vibrissse or ocular lobes. 

The species of this genus seem to be of great rarity. 

1. DlaUohius iriornatus, n. sp. 

Dense argillaceo-squaniosus, vix variegatu?, antennis rufia, 
femoribus dentatis. Long. 4^-0 mm. 

Antenna rather stout, scape scarcely surpassing the front 
margin of the thorax. Chib, rather short, oval, solid, but with the 
sutures visible. Rostrum very densely and evenly squamose, eyes 
rather large, scarcely prominent, separated by a long distance from 
the thorax, this latter short, slightly curved at the sides, and 
evidently narrower in front than at the base. Elytra very densely 
squamose, without any pubescence, the series of fine punctures 
very distinct notwithstanding the sqiiamosity. Under surface also 
densely squamose, but the clothing is on the abdomen less perfect, 
on the apical segment there being merely hairs, or rather setae, 
instead of scales. Legs rather stout, all the femora with a 
definite tooth. 

Two specimens found by the late Mr. Fryer. The 
smaller specimen is probably the male. 

2. DlaUohius mundus, n. sp. 
Dense squamosus, pallidu.^, subviridis, antennis rufis; femoribus 
iutermediis et posterioribus fortiter dentatis. Long, bh mm. 

Similar in appearance to the European P. pomonsf 
and allies ; extremely densely covered with adpressed 
scales, of a pale colour, with a very slight tinge of green, 
and here and there slightly iridescent or metallic. In 



Rhyncho'phorous Ooleoptera of Japan. 105 

most other respects extremely closely allied to D. 
inornnbis, the front femora are, however, though dilated 
and angular beneath, provided only with a very minute 
tooth. The legs are red, but on their anterior aspects 
are densely squamose. 

I have seen only two specimens of this elegant insect. 
They were found in the Main island at Nikko and 
Kashiwagi in June. It should be noticed that Mr. 
Lewis found at Nikko a single immature individual of a 
species of Phyllohmis that resembles JJ. mundus almost 
exactly. 



o. Diallohius leivisi, u. sp. 

Niger, minus dense viridi-aureo squamosus, antennis pedibusque 
rufis, illis clava nigricante ; femoribus omnibus maxime dentatis. 
Long. 6^ mm. 

A very remarkable insect, of which only a single 
specimen was found, it is a male; it differs greatly from 
the other two species of the getius, and bears in fact a 
relation to the first division of Phyllohius, similar to that 
exhibited by D. mundus and trwrnatus to the second 
division. Rostrum with the broad apical part very 
definite, not squamose, feebly bicarinate before the eyes. 
Scape of antenna nearly straight, broad at the extremity, 
8th joint about as long as broad, club moderately long, 
acuminate. Eyes moderately large, but little prominent, 
encroaching somewhat on the front of the head. Thorax 
rather large, much rounded at the sides, only a little 
narrower in front than behind, sparingly covered with 
brilliant, hair-like scales, which do not conceal the 
sculpture, this consists of moderately coarse and close 
punctures, with the interstices dull, owing to a minute 
coriaceous sculpture. Elytra with rows of large punc- 
tures, black and shining, with brilliant hair-like scales. 
Legs very peculiar, the femora flat, with extremely large 
triangular acute tooth ; tibite also compressed, so as to 
exhibit an edge externally, the lower part of each rather 
deeply emarginate, so that a sort of obtuse angle is 
formed above the middle. Under surface, shining, black, 
with very little clothing.

Yokohama : four specimens. This insect is apparently 
really congeneric with the European 8. mustela ; it has, 
however, the front of the rostrum differently formed — as 
pointed out by M. Roelofs — and, in addition to this 
distinction, the remarkable fringe of sette on the outside 
of the apical portion of the hind tibia is wanting in the 
Japanese species, 

Macrocorynds, Schonherr. 

1. Ilaci'ocorynus discoidei)s, 01., Roelofs, Ann. Soc. ent.

This E. Indian species was not found in Japan by 
Mr. Lewis during his last visit. Previously the species 
was only met with at Kagoshima, so that it is probably 
confined in Japan to the extreme south. 

Myllocerus, Schonherr. 

Six species of this genus, all peculiar to Japan, have 
been described by M. Roelofs, and I now add three 
others. M. ahnormalis might, however, be placed in 
Macrocorynus with as much propriety as in Mi/Ilocerns. 

1. Mijllocerns naso, n. sp. 

Densissime squainosus, brunneus, in elytris vage pallide-varie- 
gatus, caplte inter oculos canaliculate. Long. 7 ram. 

Very distinct from the other Japanese Mylloceri, and 
more closely allied to the Siberian M. sibiricus, Tourn. ; 
readily distinguished by the structure of the apex of the 
rostrum ; the depression of the nasal plate being much 
prolonged on to the rostrum, and forming above a very 
acute angle, surrounded by a remarkably deep and definite 
angular groove, which is prolonged as a fine smooth 
space along the middle of the rostrum, becoming more 
deeply impressed between the eyes, so as to form a short 
channel there. Scape long, rather densely setose, 2nd 
and 3rd joints of antenna very long, club elongate. 



RhyncJiopho7'ous Goleo'ptera of Japan, 107 

acuminate. Eyes coarsely facetted. Thorax much 
narrower than the elytra, nearly straight at the sides, 
and almost as broad behind as in front, the base very 
feebly bisinuate ; the surface squamose, but with a few 
large punctures, rendering it uneven. Elytra densely 
squamose, and with minute and very short sette, rising 
from among the scales; the interstices a little convex, 
and the series of punctures quite distinct. Legs rather 
long, densely squamose, slender, hind femora with a 
distinct small tooth, the others almost imperceptibly 
dentate. 

Higo, a Province in Kiushiu : one specimen. 



2. Myllucerus hlllerl. 

Myllocerus hilleri, Faust, Stett. ent. Zeit., 1., 1889, 
p. 222. 

Minor, dense griseo-squamosus, variegatus, setis erectis armatus, 
antennis rufis, baud crassis, sat dense setosellis ; femorihus dente 
parvo instructis. Long. 4-5 mm. 

Antennfe not long, rather slender, 2nd and .3rd joints only 
moderately long, the 3rd scarcely so long as the 2nd. Rostrum 
flat in front, not carinate or impressed, eyes rather small, quite 
lateral. Thorax small, greatly narrower than the elytra, not 
in the least sinuate at the base, very slightly nari'ower at the base 
than in front ; the surface densely squamose, the squamosity paler 
at the sides, the numerous setae emei'ging from the squamosity 
very minute. Elytra extremely finely striate, the strife not 
visibly punctate, densely squamose, the .squamosity sordid grey, 
with some very irregular nearly white patches, and a few darker. 
The erect sette very distinct. Legs slender, rather short. 

This insect reminds one of the European Pseudo- 
myllocenis sinuatus, but the claws are not connate. 
Amongst the Japanese species it can only be confounded 
with Myllocerus griseus, or viridulus, but is very 
distinct from them by the smaller thorax, smaller eyes, 
and by the very conspicuous setee of the elytra. It also 
differs by the flat front of the rostrum, and by the 
extreme shallowness of the excision that forms the 
buccal cavity. 
, It was found in considerable numbers at Oyama. 



108 Mr. David Sharp on the 

Notwithstanding some slight discrepancies with Faust's 
description, I have little doubt this is the species he had 
before him. 



o. Myllocerns (?) ahnormalis. 

Compactus, dense squamosus, variegatus, antennis pedibusque 
crassis, dense squamosis, illis variegatis, tibiis compressis intus 
subdentatis. Long. G mm. 

This insect is remarkable from the incrassate antennas, and 
Otiorhynchus-like rostrum. The scape is broad, compressed, 
densely squamose and setose, brown, 2nd joint also brown, 
joints 3-7 stout, covered with white squamosity, 8-11 black, the 
last three forming a compact club. Rostrum broad at the tip, 
scrobes large, converging inwards abruptly, so that the prominent 
intervening space is but narrow ; ej^es large, rather prominent. 
Thorax rather large, deeply bisinuate at the base, narrowed in 
front, extremely densely squamose. Elytra densely squamose, in 
colour at the base as if scorched, on the middle pale, immediately 
behind the pale scales, a dark patch, the apical part coloured like 
the front of the body of a pale fawn colour : striation obscure on 
account oE the squamosity. Legs very densely squamose, femora 
dentate. Under-surface densely clothed with pale squamosity.

The very elegaut insect for which I establish this 
genus, is remarkable for its long slender antennee. It is 
densely clothed witli beautiful pale green-golden scales, 
somewhat after the fashion of Phyllobius and Polydrusus. 
The scrobes are visible from the front, and have no 
prolongation. The mentum and the emargination for its 
reception, are remarkably small ; there is no trace of 
ocular lobes or vibrissa?. The legs are slender, the 
femora not dentate, the claws rather large, free. The 
hind coxae less widely separated than in many of the 
allied genera. 

1. Eumyllocerus gratiosus, n. sp. 

Dense pallide viridi-squamosus, micans ; antennis rufis, valde

Scape elongate, slender, strongly curved, all the joints of the 
f unicle very elongate, club slender, distinctly triarticulate. Rostrum 
very densely squamose, nasal depression elongate and narrow, a 
minute elongate fovea between the eyes, these moderately large, 
prominent. Thorax small, as broad in front as at the base, sides a 
little enhirged in the middle, base feebly bisinuate. Elytra sub- 
inflated, densely squamose, with numerous extremely minute 
pallid setae in addition to the scales, finely striate, interstices broad, 
slightly convex. Scutellum long. Legs slender, nearly black, 
but with much pale green squamosity ; tarsi paler, slender. Under- 
side of head deeply trifoveolate, and with a fine transverse 
impression, passing from the outer fovea to the front of the eye.

A. pallidus, Roelofs, I. c. 

The species exhibits two distinct forms, which I believe 
are the sexes, the male having the tibiae dilated and 
angulate on the middle of the inner margin, and the 
peculiar apical process of the rostrum more abruptly 
elevated and pi'olonged. I cannot distinguish A. pallidus 
as a separate species. Neither can I treat the genus as 
being provided with an ocular lobe on the prothorax.

very rare. 

Chlorophanus, Germar, Auct. 

Considerable difference of opinion has prevailed as to 
whether the peculiar chin-piece found in some members 
of this genus be a specific character or not. It is 
certainly a sexual character peculiar to the male sex, aud 
occurring only in certain species of the genns. The 
females are characterised by the possession of an ex- 
tremely long mucro at the extremity of the middle tibia ; 
this sex is also provided with a peculiar structure, in the 
form of a very hard chitinous body, probably an ovi- 
positor or piercing instrument, which, being frequently 
protruded, looks like an organ of the other sex ; it is, 
however, bifid, whereas the oedeagus of the male is single

and acuminate. The females of several species have the 
last ventral plate peculiarly formed.

elytrorum vitta lateral! fere nulla. 

Var. metallescens, n. var. Supra laate metallicus, prothorace 
distincte ruguloso ; subtus pallidus. 

A small series of this species was procured near Oyama, 
in May, 1880. Although the two varieties to which I have 
given names, seem at first sight very different from the 
type form, I feel sure that lugubris will prove to be con- 
nected with the usual state of C. grandis. I have seen 
only two examples of this form ; they were also found at 
Oyama; a specimen found at Yokohama is apparently 
intermediate. Of the variety metallescens only a single 
individual was found, the locality being also Oyama; as 
the sculpture of the thorax is an important character, it 
may possibly prove to represent a distinct species, very 
closely allied to C. grandis. 

2. CJiIorophanns planus, n. sp. 

Dilute viridis, pallide pulverulens, parum convexus, prothorace 
elytris que vitta laterale parum discreta flavescente ; prothorace 
brevi, lateribus obliquis hand curvatis ; elytrorum acuminibus minus 
flongatis ; corpore subtus albido-viridescente. Long. 10 mm. 

Pallid green, without metallic lustre. Antennae quite short, 
their club reddish, the other joints black but with much white 
clothing. Rostrum short, a little narrowed towards the tip. 
Thorax not in the least rugose, base almost straight. 

This species is readily distinguished from C. grandis 
by the characters mentioned above as well as by being 
only half the size, and by having the yellow stripe of the 
elytra extending over two interstices instead of one. The 
male has the chia-piece of the presternum not per- 
ceptibly developed. The female has the tibial inucros 
much longer than they are in the male.

The locality has not been recorded, but probably the 
insect was found at Nagasaki. 

Phytoscaphus, Schonherr. 

1. Phytosca/phus ciliaris, Roel., Ann. Soc. ent. Belgique, 
1873, p. 176. 

This is a true Otiorhynchid though its appearance 
suggests some doubt as to this fact. It was not met 
with again by Mr. Lewis on his last journey. 

PtOCHUS ? ? OBSCUKIPES. 

Ftochus obscuripes, Motsch., Bull. Mosc, 1866, p. 180. 

According to the description this is not a Ptochus, but 
belongs probably to the winged series of Otiorhynchides. 
It appears to me impossible to identify it from the 
description.

Sitones is one of the most difficult of the genera of 
Coleoptera, the species being distinguished by slight and 
unimportant points. I think there is more than one 
species in Japan, but the material yet obtained is not 
sufficient for a certain conclusion on this point. 

Edgnathus, Schonherr. 

The position of this genus has been quite misunder- 
stood. It is so close to Sitones that it is difficult to point 
to good characters for the distinction of the two ; but I

find that in E. dlstinctus the scrobes are more widely 
distant from the eyes than the}' are in Sitones. 

1. E. distinct m, Roelofs, Ann. Soc. ent. Belgique,

E. distinclus seems to be rather common in Japan, and 
varies greatly in size. 

Parasitones, n. geu. 

Generis Sitonidis per afiinis ; corpus crassum, convexum, meta- 
sternum brevissimum. 

I can see nothing to distinguish the species for which 
I establish this genus from Sitones except the short 
metasternum, and the comparatively short and convex 
form. I presume, from the rounded form of the elytra, 
and the absence of shoulders, that the species is apterous.

shorter than the 3rd, club acuminate. Eyes rather large, a little 
convex. Rostrum short, closely and deeply rugose-punctate, deeply 
impressed along the middle, the depression broader in front ; the 
sculptui'e only slightly obscured by the griseous setositj'. Thorax 
rather large, not so long as broad, much rounded at the sides, base 
scarcely at all broader than the front ; tho sculpture remarkably 
coarse, only slightly obscured by the clothing, which is inter- 
mediate between setse and scales. Elytra broad and convex, 
narrowed at the shoulders, so that the base is only very slightly 
broader than the base of the thorax, densely clothed with minute 
scales, which are griseous in colour, but varied with small darker 
spots, somewhat after the manner of Liophlceus nuhihts, bearing 
also a few short, sub-erect sette, most conspicuous on the apical 
part ; they are striate, and the broad interstices are slightly 
convex on the declivity, the striaj are punctate, at the base the 
punctures become very large, but this sculpture is much obscured 
by the clothing. Under-surface black, sparingly setose.

divergent processes, without trace of any scar, Mentum very 
broad, but not entirely filling the buccal cavity, a narrow chink 
being left on each side ; borne on a short very broad peduncle. 
Rostrum moderately long and broad, without nasal plate, scrobes 
exposed above in front, but afterwards lateral and descending, 
moderately broad and definite. Antennae sub-terminal, funiculus 
7-jointed, the 7th joint very abruptly separated from the 
club. Thorax elongate, without ocular lobes or marginal cilise ; 
coxal cavities nearer to the front than to the hind margin. Front 
tibias produced internally at the tip, inner margin not denticulate. 
Middle coxte slightly separated ; mesosternal side-pieces sub-equal 
in size. Metasternum quite short. Hind coxEe not widely 
separated ; first ventral segment behind the coxae, only equal 
in length to the second, which again is but little longer than the 
third or the fourth, these two being almost similar. Hind tibiae 
broad at the tip, but the outer margin is laminate, not cavernose. 
Tarsi pubescent beneath ; claws rather small but not contiguous at 
the base. 

This genus seems to be an extremely isolated one, and 
it would be very difficult to assign it a place in any of 
the divisions of Lacordaire, or of Leconte and Horn. I 
think it had better therefore form a distinct group 
to be placed between the Otiorhynchides and Cylindro- 
rhinides. In appearance it is more like Otiorhynchidas, 
than any other of the groups of Rhynchophoraj and is, in 
fact, somewhat similar to an elongate nai'row Liophla'us. 
The structure of the mandibles would on the N. American 
system, quite remove it from the Otiorhynchid«, and I 
should myself take this view, were it not that in some 
species of the genus Peritelus — P. senex, e. g., one of 
the sexes has the mandibles formed in a somewhat 
similar manner. The genus is, however, certainly not at 
all allied to Peritelus, and it seems almost equally widely 
separated from Meotiorhynchus in which an abnormal, 
and again somewhat similar structure of the mandibles 
exists.

long as the Ist; club rather small, very compact, pubescent, 
acuminate. Rostrum narrower than the head, nearly twice as long 
as broad, strigose-rugose, unimpressed, with a fovea between the 
eyes, these moderately large, rather convex. Thorax rather longer 
than broad, rounded at the sides and considerably narrowed 
in front, covered with a peculiar dense intricate sculpture, with a 
narrow smooth space along the middle. Scutellum very short and 
broad, but quite distinct. Elytra elongate oval, base as broad as 
the thorax, shoulders not prominent ; covered Avith a fine sculpture 
rendering the surface somewhat leathar-like, and bearing, in 
addition to long erect setae, some fine depressed setae, representing 
scales : there is no trace of striation or punctuation. Under- 
surface destitute of scales ; ventral segments quite shining 
sparingly punctate. 

Mr. Lewis received five examples of this interesting 
insect from Ketoi one of the Kurile Islands, in 1881. It 
raises a lively desire to know something more of the 
insect fauna of these islands, of which we are at present 
in almost complete ignorance — at any rate, so far as the 
Coleoptera are concerned.

V. Notes on Flower -Haunting Biptera. By Geoege 
Fkancis Scott-Elliot, M.A., B.iSa, F.L.S., etc., 
communicated by Herbert Goss, F.L.S. 

[Read February 10th, 1896.] 

I HAVE recently been enga^^ed in writinf^ a Flora of 
Dumfriesshire, and on beginning, it seemed to me advis- 
able to make a new departure in several respects from 
the plan usually followed in such works, which is 
practically that of the late Mr. Hewett C. Watson drawn 
up in 1851. Amongst other points I have thought it neces- 
sary to observe insect visitors, and for this reason. The 
entire dependence of most flowers on their insect clientele 
for fertilisation has been proved over and over again, 
and therefore it follows that to understand the distribu- 
tion of species in any small area, it is necessary to know 
the insects which visit the species in that area. More- 
over there are many theories at present abroad as to the 
origin of variations by natural causes, and as most 
botanical characters depend on those parts of the flower 
which are adapted to insects, the importance of a know- 
ledge of these latter can scarcely be overrated. 

Besides their importance in this respect, as being a 
possibly direct agency in the origin of variations in 
plants, insects must play an enormous indirect part in 
the isolation of flowers. If flowers of the same species 
are growing partly inside a sheltered and shady wood 
and partly on the bare ground outside that wood, it 
seems to me, from my own observations, that they will 
most certainly not be visited by the saine insects. It is 
not improbable that a Bombus or hive bee, or possibly 
a butterfly, will visit both the forms outside the wood 
and those within it ; but I do not think 1 am at all rash 
in saying that probably not 5 per cent, of those outside 
will be fertilised by pollen from those inside the wood, 
and vice versa. This means, for reproduction, nearly 
perfect isolation, and, therefore, just as we iiud in the 
case of oceanic islands, the formation of new varieties 
may proceed indefinitely.

118 Mr. G. F. Scott-ElHot's notes 

I must, however, state at once that I have no pre- 
tensions to be an entomologist, and that in the deter- 
mination of the insects 1 have not attempted any naming 
on niy own part, but have trusted entirely to the 
kindness and skill of Mr. R. Service and Mr. E. 
Brunetti. The flowers, whose visitors have been caught 
by myself or my friends the Misses Hannay and Taylor 
and Mr. Armstrong, are nearly 300 in number, and in 
the work alluded to, the insects are put in their proper 
place after the locality of each species.* I found, how- 
ever, as I proceeded with the catching of insect visitors, 
several very great difficulties. One is the want of any 
handy book of English Diptera by which one could tell 
the particular group of Diptera at a glance when in the 
field. I do not see why such a book should not be very 
easily produced by some of the members of the Entomo- 
logical Society. About five plates ought to enable one 
to tell at once the group (AsilidR% Bombylidie, Gunopida?, 
Dolichopida?, Empidiv, LeptidcV, MiiscidcV, Stratiomyidx, 
Syrphida', etc. ; there are twenty groups or families 
given in Midler's " Fertilisation of Plants," p. 641. The 
number of species given in this work is 253, so that a 
short account and clavis of each genus and of the 
species in c.;/., Syrphidw and Boinhylidx would not make 
a book of more than a hundred pages. 

The next difficulty was insuperable. It is not possible 
to be at the side of every flower in the flora for every 
hour in the day, during the whole time that it is in 
bloom, for obvious reasons. I question if it is possible 
to do in a thorough manner, more than six species in a 
season. Hence the visitors of these oOO flowers are 
simply the usual common forms. 

The first interesting point which I noticed with regard 
to both Diptera and Hymenoptera was that they are 
extraordinarily quick to see even the slightest motion. 
By remaining perfectly still one can observe the shyest 
Syrphid at work, but a very slight gesture of the hand 
is sufficient to send it ofl" like a flash, and unless one 
remains very still there is no chance of getting the 
majority of visitors. 

The next point, which can only be proved by observa- 



■'-■ A list of insects with the flowers which they visit is placed 
at the end of this paper. 



on Floiver-Haiinting Diptera. 119 

tion, remembering tlie foregoing hint, is mentioned chiefly 
in order^ if possible, to get some information from those 
present at this Meeting. I have come to the conclusion 
that the majority of Diptera have a recognized space up 
and down which they are continually flying. I have 
frequently had to remain as quiet as possible for three 
hours beside some interesting flower, and on these 
occasions I have seen the same fly perpetually flying up 
and down within perhaps 10 or 15 yards, occasionally 
stopping to rest and then resuming its patrol. For the 
carrion flies the phenomenon is veiy easy to observe, 
and I fancy that the whole country is really marked out 
into beats for each individual or pair. If a piece of 
carrion or excrement is deposited on a particular spot, 
it is astonishing that it should be so soon covered by 
hundreds of Lncilia Caesar, Scatophaga, etc. In fact, 
I have a strong suspicion that these creatures divide the 
ground in the way that vultures do in tropical countries, 
and that when the first one detects the smell, the 
difierence in his flight or his absence from his proper 
place tells that in the next beat, and so on ; the know- 
ledge is thus conveyed with astonishing rapidity from 
beat to beat, and crowds continue to flock in until the 
first comers are satisfied and fly back to their places. I 
mention this as the result of observation, though not by 
an entomologist, and chiefly with a view to extracting 
information. The importance of it will be obvious with 
regard to the question of isolation already mentioned, for if 
every fly, or at any rate, most of the flower-haunting species 
usually remains or remain in the same small locality under 
ordinary conditions, it is obvious that there is practical 
isolation in very circumscribed habitats. The larval 
forms of Diptera and the plants on which they feed seem 
to be very little studied, and this is also of great impor- 
tance to botanists, because I fancy that this has a great 
deal to do with the occurrence of flowers in great 
numbers at definite places. Thus on the bare wind- 
swept low-lying seashore, between the Annan and Kirtle, 
I found the Diptera very few in number and particularly 
limited in species. Such flies as Lucilia, Anthomyia 
radicum and Chortophila, appeared to fertilize most of the 
seaside plants. On the other side of the Solway, 
where there are cliffs, and these are interrupted by 
bays and many small burns, the abundance of 



120 Mr. G. F. Scott- Elliot's notes 

Diptera is extraordinary. I suspect the shelter 
afforded by these bays aud valleys has much to do with 
this abundance. 

Speaking generally, these flower-haunting Diptera 
appear to be far most frequent on plants which grow in 
enormous numbers wherever they do occur. Ihus on 
Spergiila arvensis I found Syritta, three species of 
Platychirus, Bhingia, Empin vitripennis and many 
Anihomyia, Scatophaga, etc. This was also the case 
on the common watercress, which is visited by Volucnlla 
homhylans, EHstalis arhustorum, E. sepulchralis , Helo- 
phihis pendulus, Syritta pipiens, Platychirus dypeatus, 
P. peltatuf!, Empis lici<hi, and fourteen other Diptera and 
Coleoptera. Ou the more local and scattered N. pahistre 
I only discovered three common Anthomyids. 

Probably this explains why it is that so many plants 
have taken to contracting their inflorescence so that a 
very large number of flowers cau be visited by insects in 
a very short time. 'J'hus, of all the plants which 1 have 
studied, perhaps the following are the most visited by 
Diptera and other insects, viz., the dwarf elder, sheepsbit, 
ITmheUifcra', particularly Cicuta and Angelica, and of 
course the Composita', notably Aster tripoUuni. 

On flowers which come early in the spring or late in 
the autumn, there is, in favourable weather, quite an 
extraordinary number of insects. I consider this to be 
probably due to the whole available insect force being 
concentrated on just those few forms which happen to be 
in bloom. 'J'he following list of visitors : — Hive bee, 
five species of Bovihus, Pieris napi, EristaUn pertinax, 
Sericomyia horealis, Platychirus albimanus, Syrphus 
halteatus, S. topiarius, Antliumyia radicitm* would be at 
once supposed to belong to some very high type of flower, 
such as a Labiate, but in reality they were all caught on 
the common bramble or blackberry, which probably 
attracted them because the special bue-flowers were not 
then in bloom. Similarly the early spring buttercup or 
pilewort rejoices in a large number of guests, e.g.. Hive 
bee, Mantiui napi, Melanostoma, Platychirus albimanus, 
Empis piunctata, E. bilineata, Hyetodesia basalis, Chilosia 
sp., Anihomyia sp., and Meligethes.

on Flower-Haunting Diptera. 121 

One point which comes out very clearly in many 
different cases is also illustrated by the buttercups. 
That is, that the water-loving forms of a genus, such as 
in this case R. aquatilis and B. sceleratus, are visited by 
perfectly extraordinary swarms of very low-class Diptera, 
while the guests of the land-forms though fewer in 
number, are of a much higher type (^.g., R. ficaria, 
V.S.). These water species of a genus are also usually 
botanically less specialised than their land allies,* so that 
the specialisation of the insects and of their hosts has 
advanced together. 

This corresponding rise in the scale of specialisation 
of guests and host together comes out very clearly in a 
variety of genera, and is strongly in favour of the 
correctness of the general theory to which I shall allude 
later on. Thus Geutn urbanum is yellow and of a simple 
open type, and is visited by Siphona geniculata, 
Hydrotea dentipes, Anthomyia radicnm, and Hylemyia 
sirigosa, 

Geuni rivale is red and of a very much more com- 
plicated type, and this is visited by Bomhns muscorum 
and hortorntii, as well as RJtingia rostrata. 

Epilohium angustifoliunb has also a larger, more 
tubular and one-sided flower than the ordinary willow 
herb E. monfanum. Hence ono finds upon it the hive 
bee and bumbles as the most regular visitors. {Ajns, 
Bombu-s Jncorum, B. pratonim, Vespa sylvestris, and 
Cyrtoneura stabnlariti). 

The other only received the visits of Syritla pipiens, 
Platychirus clypeatus, tSiphona cristata, and Anthomyut 
radicum. 

The cloudberry, Rubns duirnxmorus, is also either 
degraded or an earlier form of Rubus than the common 
blackberry, and hence it is not surprising that only a 
species of Empis, which Mr. Brunetti thinks is new to 
Britain, Anthomyia radicum, Siphona cristata, and 
Hydrotea dentipes were discovered upon it. Two very 
curious instances of the effect of structure of flower on 
insect visitor may be mentioned in this connection. 
Corydalis, a kind of poppy, belonging to one of the earliest 



i?. sceleratus has small petals, conical axi?, etc., and R. aquatilii 
is white, not yellow. 



122 Mr. G. F. Scott-Elliot's notes 

and least specialised orders, has a corolla closed like 
that of the peas, and its visitors are the regular pea- 
flower types, Apis, three species of Bomhus, Apathus, 
and Andrena. The Lahiatse are, again, of all orders the 
most obviously adapted to bees, and the most constantly 
visited by them; for instance, of the fifteen flowers of 
this order observed by myself and friends, the visitors 
were invariably bumble bees and hive bees, except in one 
case, — Mentha arvensis, — where we found only Scato- 
phaga, Siphona, Hydrofea, Lophius, and Teleplwrus. This 
flower is, again, a water-loving form, and also of very 
mucb simpler structure than any of the other plants of 
this order studied. 

The flower-haunting Diptera are very much more import- 
ant than most observers imagine in fertilisation. Thus 
such genera as Galium, Myosotis, some species of Veronica, 
and the smaller geraniums, particularly G. luciduni, appear 
to be chiefly dependent on 8yrphidss for setting seed. 
Now in Sir J. Lubbock's book, " Ants, Bees, and Wasps," 
these Diptera are somewhat markedly left out in the 
cold," so that a few facts, drawn from my experience, as 
to their colour, sense, and intelligence, may be of interest. 
I am obliged to admit that they are more frivolous than 
bees, and perhaps visit only three flowers in half an hour, 
during which time a Bomhus might visit at least one hun- 
dred. On the other hand, they do not, as a rule, mix their 
honeys, but keep pretty steadily (though not so closely 
as a true bee) to one particular nectar. I have seen this 
particularly with Empis vitriptennis when visiting Linuin 
catharticwm, which was growing along with many other 
flowers. It kept steadily to the Linums for a considerable 
time. 

Their colour sense is quite clearly obvious from the 
following table. The most remarkable fact in it is, that 
not one of these sixteen Diptera is confined to yellow and 
white flowers. Sixty-one per cent, of the flowers visited 
by Rhingia rostrata are blue or red, and usually the 
white flowers visited are under 50 per cent, of the 
whole.

It thus appeal's that, though BomJjus muscoruni is far 
more red-loving than the higher Diptera, this is by no 
means the ease for the smaller bees. There are in fact 
only four of the sixteen Diptera quoted, which are 
fonder of white flowers than Andrena alhicans and 
Allantus nothi. The fact that blue and purple flowers, 
which are held by Miiller and others to be particularly 
adapted to bees, and almost entirely fertilised by them, 
are very frequently visited by these Diptera, is particularly 
important. Empis hilineata, Platychirus alhimanus and 



^' Miller gives for flies 67*9 per cent, white and yellow flowers 
and 303 per cent, of red and blue ; for higher bees 36*6 per cent, 
white and 63'3 per cent, red and blue, cf. 29 per cent, white and 
71 per cent, red and blue in this table ; for small bees 63'8 
per cent, white and 36'2 per cent, red or blue ; while here it 
is 83 per cent, white and 17 per cent. red. '"Alpenblumen," 1881, 
p. 512. 



124 Mr. G. F. Scott-ElHot's 7iotes 

clypeatus, are more blue in their tastes even than Bombus 
muscorum ; and no less than ten of these sixteen Diptera 
habitually visit flowers of this colour. Very much the 
same deduction can be drawn with regard to their taste 
for red tints, Platychirus moMicatus and Rhingia are 
nearly as fond of red as the Bombus muscorum, and only 
five out of these sixteen Diptera are less fond of red 
than Andrena albicans and Allanfus. 

If, in fact, we taks the average colour-preferences of 
these sixteen Diptera, we find them to be as follows : 
Average of Diptera : 46 per cent, white ; 22 per cent, 
yellow ; 21 per cent, red; 10 per cent, blue ; from which 
it clearly follows that these Diptera are of far more 
advantage to red and blue flowers than either Andrena 
or Allantus. 

When, instead of taking colour in flowers as a base of 
classification, we look to complexity of structure ; we 
find ourselves at once in a position of considerable 
difficulty. The structure of flowers cannot be easily 
brought into perfectly definite and unmistakable groups 
such as are furnished by the four colours already 
mentioned. 

If we group flowers according to their natural orders, 
and tabulate insect visits to those orders, the result is 
quite meaningless, because plants belonging to the same 
order, or even genus, are in respect to insects of very 
different complexity. Thus, Geranium sylvaticum, e.'/., 
is visited by insects which bodily enter the open cup-like 
flower; while (jeranium lucid uni is visited by insects 
which stand on the petal and insert the proboscis into 
the narrow short tube. Hence I found on Geranium 
sylvaticum, Ajns, Bomhus pratorum, B. 7)iuscorum, 
Halictus cylindricus, Nomada lateralis, Empis tessellaia, 
E. pennata, E. vitripennis, and sp., Platy chines pel- 
tatuK, P. manicatus, and five Anthomyidx, which could 
not be named. That is a very varied and extensive 
clientele. 

On Geranium lucidum, on the other hand, I only- 
found Syrphus cinctellus, Melanostoma mellinum, Plafy- 
chirus manicatus (though in great numbers) ; but no 
Antliomyidse or Hymenoptera. This represents, of 
course, a very different set of visitors. The difference 
in Leguminosse betwixt the small yellow trefoils and 
Ornithopus and the rest of the order is also most 



I

remarkable, and similar differences occur in almost all 
orders and more than one genus. Miiller tabulates 
several orders with their visitors, and his example has 
been followed in this country by Mr. J. C. Willis aud 
others. 

However, as a rough classification, in order to obtaiu 
some insight into the intelhgence of these Diptera, I 
arranged all the flowers which I have examined into six 
divisions : — 

1. Uanuncidm group, including all open flowers rich 
in pollen, into which any insect may enter bodily. 

2. Crucifer group, including such forms as Umhelli- 
ferx, Galium, Alisma, as well as all Compositse with 
extremely short florets, such as, e.g., Daisy. 

3. Veronica, Mijosotlx, etc., i.e., flowers with a distinct 
though short tube, and which involve higher intelligence 
in their clients than the preceding. 

4. The long-tubed Compositse such as Cardu us, and also 
Lychnis, etc. 

5. The smaller Legnminosfe, Medicago, Ornithopu>>, and

on Flower-Haunting Diptcra. 127 

In words this may be translated to mean that these 
Diptera are, on the whole, more intelligent than the 
lower class Hymenoptera. 

Three species of Diptera visit species of Orchidacea?. 
In fact, Sijrphus rihesii, Eristalis pertinax, and Empis 
vitripennis, appear to be the main agents in effecting the 
fertilisation of our common British forms. The only 
other insect which I have myself as yet discovered on 
these plants is Argynnis aglaia ; my friend, Mr. Arm- 
strong, however, reports that he has observed certain 
" large brown and sulphur moths " feeding on Hahenaria 
h if alia. ^ 

Nine of these Diptera are found either on the larger 
Leguminoase , flowers of the Bugle type, or on Orchids ; 
and this is sufficient to show a very considerable amount 
of intelligence. 

It is not easy to bring these insects into any series 
which will show their relative abihty, but judging from 
the preceding table, the following is a pretty sound 
grading of their intelligence : — 

Class 1. Bombus. 

„ 2. Empis vitripennis, Eristalis pertinax, 8i/rphiis 

rihesii. 
„ 3. Empis livida, Melanostoma, Platychirus alhi- 
manus, P. clypeatus, P. peltatus, RJiingia, 
Allantus. 
,, 4. Remainder, including Andrena albicans. 

It remains to point out the bearing of the foregoing 
remarks on the use of Diptera and other insect visitors. 

I have not found any confirmation of certain theories 
which suggest that the actual probing of an insect's 
proboscis, or the friction of its feet have any influence 
in determining the growth of hairs, or the flow of sugar 
to that particular part of the flower ;t it is, of course, 
probable that the continual draining away of nectar from 
a certain spot will induce a larger supply to come to that 
particular position, just as the continual use of a certain 
muscle will produce a greater enlargement of it. It is 
even probable that such a demand for nectar may be 
inherited, but this is not yet proved. 

* I have taken specimens of Leucania turca in the New Forest 
with the pollinia of this species attached to their heads. — H. G. 

t The researches of M. Kustenmacher on Galls, Bot. Gaz., xx., 
p. 497, are, so far as hairs are concerned, rather against this view, 
which is not, to my knowledge, supported by any direct evidence. 



128 Mr. G. F. Scott-Elliot on Floicer-Haunting Diptera. 

On the other hand, I am far more certain of the depend- 
ence of flowers on insects than I was before. When 
such minute forms as Draha verna, Siihnlaria aqnatica, 
or such " typical wind-fertilised " species as the Burnet, 
Salad Burnet, and Dog's Mercury, and species of such 
genera as ThaUdrum and Planfago are found to be 
visited by insects, as I have myself seen in the course of 
my work, it leads one to doubt if wind-fertilisation is 
ever of much use. A simple mathematical proof shows 
that the chances of a piece of pollen from one flower 
reaching that of another growing within a foot of it, is 
about one to three hundred; but if an insect is on one 
flower, for any purpose, the chance that it will go to the 
next visible flower is probably ten to one. 

It seems to mo that these Diptera will probably yield 
the most valuable results in investigating the origin of 
plant species, for they visit all kinds of flowers, and 
possess both colour-sense and intelligence, as I have 
tried to show. In fact, it is to them that we probably 
owe all the neatly made, small and bright-coloured 
forms which are particularly abundant in this country. 
It is not possible now to say definitely, that this or that 
insect is responsible for such a flower (though I think, 
myself, I could say it for certain forms) ; a genus in 
which seven species have been studied by us, and 
on which we have found hive bees and bumbles in all 
cases except two, would imply a very high botanical 
structure. Yet this genus is Hijpericum, the flowers of 
which are very simple. 

Still I think from my own experience, there can be no 
possible doubt either that the flower has modified the 
habits and structure of the insect, or that the insect 
has modified the habit and structure of the flower. Of 
the two, it seems to me, as a botanist, that the flower 
has been the predominant factor ; but this opinion may 
be the result of prejudice. 

Note. — j\Ir. G. H. Verrall, who has kindly looked through this 
paper, says that it is difficult to distinguish Emph cltripennts from 
about twenty closely allied species, several of which are yet un- 
recorded as British ; that Eristaliif jiert'tnnx has never been clearly 
differentiated in print, and that both Syrphus chictellus and 
S. ribesii are very difficult to distinguish from numerous allied 
species. — H. G.

YI. Notes on Pujp^ — Orneodes, Epermenia, Clirysocorys, 
and Pterophorus. By Thomas Algernon Chapman, 
M.D., F.E.S. 

[Read November 6th, 1895.] 

Plates VI. & YII. 

This comraunication is in continuation of my previous 
Notes on Puj)^. (Trans. Ent. Soc. Lond., 1893-94). It 
refers especially to a character of certain pupte, that 
occurs and appears to show a relationship in a large group 
of TM?-eMi«, and incidentally it deals with the plume moths, 
and some forms that have, or are supposed to have, 
affinities with them. 

I may, in the first place, correct two errors in my 
previous papers ; the most important of these, or at any 
rate the one for which I feel I am most to blame, is as 
to the free segments in the Limacodidfe. In the Lima- 
codids, not only are segments (abdominal) 3, 4, 5, 6, free, 
but also 1 and 2, in the sense in which I now understand 
the word, that is, they are not soldered to the wings and 
appendages, and appear to be capable of independent 
movement on each other. It is extremely probable that 
the insect, however, never does so move them, and rarely, 
if ever, indeed, moves the others, being packed closely in 
and well pi'otected by its cocoon. In explanation of my 
error, I may say that these two segments are so closel}' 
applied to the appendages, that when one separates them 
by ti'action in the living pupa one fears to tear the 
delicate pupa to pieces, and suspects that the separation 
is made by breaking down actual slight soldering — an 
occurrence which I have pointed out takes place very 
readily in those pup^ in which the process of fusion of 
the parts is in its early stages, the greater part, that is, 
of the lower " Incompletsi " in fact, such as Limacodids, 
Nepticulids, Adelids, etc. Then in the empty case all 
segments and appendages are so freely separate that this 
state of the pupa throws no light on the extent of solder- 
ing in the living pupa. The error is only of importance 

TRANS. ENT. SOC. LOND. 1896. PART II. (jUNE IST.) 9 



130 Dr. T. A. Chapman's notes on Pupa", 

as sliowing that the Limacodids must take even a lower 
place than I had given them. 

The other error was as to the structure of the pupa of 
the Nolidx, due to my having only dead or empty pupo3. 
An examination of living pupa3 shows that this pupa 
possesses only one free segment, viz., the fifth (abdominal), 
and is, therefore, probably in no way directly related to the 
Macro-heterocera. I hope to deal with this more fully in 
some future communication. 

There is a pupal piece I have not hitherto referred to, 
having no clear idea as to its relationships, and have 
passed over as a portion of the anterior head cover (or 
face-piece), which no doubt it is. Nor have I studied it 
enough to know its range, except that it occurs chiefly in 
low micro forms. It is often a separate piece between 
the face-piece proper and the dorsal head-piece ; it does 
not divide in the middle line on dehiscence, but remains 
in one piece. It is probably the dorsal-plate belonging 
to the antennal section of the head, as distinguished 
from the face-piece proper, which is the anterior plate 
or plates belonging to the mouth parts. Though it has 
no bearing on the subject of this paper, I take this 
opportunity of calling attention to it. 

In my paper, read Feb. 22nd, 1893, I made it suflS- 
ciently clear that the section Incomplete included the 
more generalised and ancient forms, and that the Ohtectx 
were more specialised and more modern. By putting 
this, however, into a tabular form, I believe I conveyed the 
impression that there was some sort of gulf between 
them, and what is especially erroneous, though much the 
same thing in another form, that the Ohtedx. were more 
closely related to each other than any of them were to 
any of the Inconipletse^ and this misapprehension was 
probably favoured by my taking the number of free 
abdominal segments as the most typical indication of the 
extent to which a pupa belonged to the more generalised 
foi'ms. No doubt that is so, but the other directions in 
which fusion of parts (the character of Ohtectie) has 
failed to obtain, is also of importance. 

The feature of an Incomplete pupa that is usually most 
persistent — that is, appears most frequently in the highest 
forms — is the presence of the portion, that I at one 
time supposed might be an anterior portion of the pro- 
thorax, but which I think there can be no doubt is the 



Orneodes, Epermenia, Chrysocorys, and Pteropliorus. 131 

dorsal-plate of the head, or of the last segment of the 
head, viz., the one to which the eyes belong. This is 
present in no true butterfly, but is present in Skippers, 
and carries the eye-covers with it on dehiscence ; it is to 
be found in a few families of the true Macro-hetewcera, 
some Geometers, the Thyatlridse, and the Lasiocamjyidx, 
suggesting that amongst these we may find the lowest 
families of the macros, and their line of origin from the 
micros. Illogical and exploded as the terms macro and 
micro may be, I still think their retention useful for the 
present, in place of such periphrases as the more special- 
ised and more generalised, etc., meaning by macro the 
higher Ohtectse, and by micro the lower Incompletse, and 
describing intermediate families as possessing such-and- 
such macro or micro characters. In this connection I 
should like to allude to the extent to which I regard the 
Tineina as not being a homogeneous superfamily or 
family. So far as it is not a mere question of names — i.e., 
what we shall call a family, and what a sub-, and what a 
superfjimily, what a tribe, and so forth — but a question 
of fact, that is, of the amount of divergence between the 
several groups, then the pupal structure shows that there 
is a divergence between the Gracilaridai (including Litlio- 
colletes), the Nepticnlida}, and the Argyresthidie, which is 
much greater than that between, say, any family of 
Noctuina and the NotodontidEe. 

That this view is not without foundation is tolerably 
evident when we find Prof. Packard, whose authority 
on such a matter is of the highest, not merely dividing 
one genus of Tinem {Micropteryx) into two families, which 
was all I had courage for, but erecting one of them 
{Eriocephalidai) into a suborder, and the other as an 
equivalent to all the remaining families of Lepidoptera. 

Being somewhat emboldened by this advance, and 
adopting Prof. Packard^s conclusions on this point, and 
reviewing the apparent relationships of the most gene- 
ralised forms of Lepidoptera, feeling also that we have 
not sufficiently realised the extent of our unacquaintance 
with very many forms that are required to bridge over 
the divergences that exist between even these earliest 
forms, an ignorance due to our not having met with 
them, not having learned their life-history so as to under- 
stand their positions, or, and most frequently no doubt, 
to their no longer existing, I would suggest that there 



132 Dr. T. A. Chapman's notes on Pufee, 

were other families of PalFeoleindojitera (Packard) 
besides the Micropterygklx. Hejncdus, and Nepticula, 
and possibly Psyche, being derived from Palieo- 
lejndoptera, without any intermediate forms that we 
now possess, and yet certainly not from the Ilicroptery- 
gidm ; and that the lines of evolution diverged from this 
low point. 

Micropteryx unquestionably led directly to the Adelidse, 
(^Prodoxidai, Packard) via Incurvaria, and thence to the 
great mass of the families of Tineina, including two at 
least of the families I have before me in this paper. 

There happens to be one character (pupal) which first 
appears in the Adelidfe, and which may, I think, be 
taken as strong evidence that any family possessing it 
belongs to this series. This character is a remarkable 
narrowing of the prothoracic plate, and a great increase in 
the size, especially longitudinally, of the dorsal head 
plate (cephalothoracic piece). This conformation gives a 
very definite facies to all the forms that possess it to any 
decided degree, in consequence of a further fact, that is 
always more or less associated with it, though why it 
should necessarily be so is not very clear — this is, that 
the narrow ribbon of prothorax forms a depressed neck, 
and the head swells out in front, sometimes with quite a 
globular projection. 

This series is especially the Tineid as distinguished 
from theTortricid stirps, beginning with the Adelids and 
passing through the Tineid^', with sundry branches, 
reaching in Epermenia the critical point in which it 
passes from the micro to the macro type. Having 
Orneodes as a definite and probably terminal form derived 
from this point, but passing on to the higher families 
that I have called Pyraloids, a term I desire to restrict to 
forms usually classed as Tineina, making the Pyrales a 
separate group, but including with them Depressaria and 
some other so-called Tineid families. 

These Pyraloids include Yp)onymeuta, Argyresthia, 
Plutella, Laverna, Elachista, etc. All these are char- 
acterised like the Pyrales, and like the whole lower part 
of this stirps by the pi^eservation of the maxillary palpi, 
not only in the pupa but also in the imago. Coleophora 
deserves separate consideration : it is not only equally 
high with these in having a generally obtect form of pupa 
(five and six only, free in both sexes), but is higher in 



Orneodes, Ejjermenla, Chrysoconjs, and Pleroplwrus. 133 

having lost the maxillary palpi. It is, however, lower, in 
one sense perhaps higher, in having carried the cha- 
racteristic peculiarity of the stirps to an extreme point, 
viz., the prothoracic plate is dwindled to so narrow a 
quantity, that in many species (I cannot, of course, 
answer for all) it is quite evanescent in the middle line. 

For these and for the following reasons also, I am 
inclined to claim for Coleophora that it is derived from 
Adelidfe by a line of descent pai'allel to (and of course 
as long as) that of the Pyraloids, but quite separately 
at least from a very low point. I am too ignorant to be 
able to say that all intermediate representatives have been 
lost, but they have not yet been recognised by me. The 
other points of resemblance are especially that the some- 
what unusual structure of the last segments of the pupa 
of Coleoplwra is almost identical with that of Lamproni'a 
and some other Adelids, of BucciiIatricV and other of the 
lower forms. That it is a casebearer like AdeUdre is, 
of course, not without its significance, though it would 
not be difficult to believe this to be an independently 
acquired habit. Another important point of resemblance 
is in the ovipositing apparatus. 

No doubt these are structures given to great variation 
and may differ exceedingly in closely related forms, but 
when we consider the remarkable specialisation of this 
apparatus in Adelids, and that this is practically lost in 
the Pyraloids, it seems impossible to believe that almost 
precisely the same apparatus would be again elaborated 
for a purpose that would be served by a much sim2:)ler 
structure equally well. 

In Mirro'ptenjx the dorsal plates of the ninth abdominal 
segment form a cutting knife. In Inciirvaria the dorsal 
plate of the eighth is partially modified for its support. In 
all the other Adelidm I have examined, both dorsal plates 
are extremely modified (as described by Dr. Wood, 
Ent. M. M., vol. 27, p. 175), one as a knife and the other 
as a support. In Coleophora the structure is almost pre- 
cisely the same, except that the horny knives of the 
Adelids, hard, sharp, and polished for cutting plant 
tissues, are in Coleophora rounded and furnished with 
tactile hairs, and are adapted for searching in inflorescence 
and for a nidus for the eggs, but not for cutting. 

I may refer parenthetically to Gracllaria and Litho- 
colletis, which have advanced to the stage of having the 



] 34 Dr. T. A. Chapman^s notes on PujJX, 

first four abdominal segments fixed, retaining- the normal 
armature and method of dehiscence of micros ; they have 
the large head-piece characteristic of this series. They 
have also lost the maxillary palpi, so that they are not 
in the direct line to the Pyraloids and must be regarded 
as occupying a terminal position in that branch of the 
series to which they belong — and probably came from 
Adelids by way of Tischeria, missing Tinea. 

One more immediate object in this paper has reference 
to the degree of relationship, or want of it, existing 
between Orneodes and Ptevoplwrus. Chrysocorys also 
has long been associated with Fferopliorus in our list, and 
as Orneodes and Chrysocorys both belong to this series 
with large head plates, it is necessary to refer to it 
thus in some detail. I have associated with them the 
genus (family) Epermenia, as it occupies a somewhat 
critical position in the series. 

It is remarkable that the pupa with the free seventh 
segment of the male has so universally the habit of 
emerging from the cocoon. Pterophorus was for a long 
time the only exception I knew of. But Epermenia forms 
another. Since it may very naturally be supposed that I 
regard this unusual coincidence as evidence of alliance, I 
hasten at once to say that I think it has no such signifi- 
cance. The fact is that the habit and the structure 
appear to have always been lost together, except in the 
case of Pterophorus (and again in Hepialus, which is the 
reverse case) ; and the wonder is that there should not 
be more instances than that of Epermenia, in which we, 
as it were, surprise the change actually occurring, and 
find that the habit does cease a fractional time before the 
structure. 

If we suppose Epermenia, which preserves the maxillary 
palpus, to lose the freedom of the male seventh segment, 
we have in essentials the pupa of these families, which I 
group together as Pyraloids, viz., Elachista, Laverna, 
Asyc/ina, Plutella, ArgyrestJiia, Yponymeuta, and some 
others. Pyrales differ little from these except in the 
much diminished size of the dorsal head-plate and, in the 
higher genera, in the appendages not projecting beyond 
the fourth abdominal segment. Still I have not yet quite 
satisfied myself that the Pyrales are really a continuation 
of this series. 

Orneodes diflfers from Epermenia in losing the mobility 



Orneodes, E2')erme7iia, Clirysocorys, and Ptero^liorus. 135 

of the seventh segment, but it loses also the maxillary 
palpus, so that it is not in the direct line of the Pyraloids, 
but a lateral branch. 

Clirysocorys retains the same formula of free segments 
as Tinea, and has retained also the habit of emerging from 
the cocoon for dehiscence. It has, moreover, entirely modi- 
fied and altered the dorsal armature of the abdominal 
segments which most forms that retain that habit pre- 
serve, and has in all its stages attained a very modified 
and isolated position. 

Pteropliorus presents as a pupa no point of connection 
at all near to any of these others. As to its relation to 
Clirysocorys, the pupge of both belong to the forms with 
three free segments in the female and foar in the male. 
This is, however, a very large group, and possesses forms 
as far apart as Tortrix, 8esia^ Cossus, Tinea, Simfethis, 
Castnia, etc., and it is quite possible, perhaps even pro- 
bable, as I have already suggested, these have more than 
one line of origin from lower forms, so that this does not 
go very far in showing relationship. 

Pteropliorus has acquired a habit which no other pupa 
in this section possesses, except Hyj^ercaUia, if it be a 
true Pyraloid — viz., it attaches itself by a cremaster and 
has no power of progression, and possesses no maxillary 
palpus. Clirysocorys has a small maxillary palpus, and 
possesses, in full vigour, the power of emerging from its 
cocoon. Especially perhaps it has a very decided and 
definite cocoon. I have not seen any Pterophorus cocoon 
anywhere near it. The most important point of all, 
perhap?, is that Clirysocorys has a very narrow pro- 
thorax and a fairly large head-piece, and belongs there- 
fore to the Tineid stirps; the reverse being the case 
in Pterophorus, yet the minute trace of head-piece carries 
the eye-cover on dehiscence. As regards its panoply of 
hairs, spines, bristles, and other appendages, the different 
species of Pterophorus present immense variety, some 
being very smooth and plain and with a delicate shell, 
others most elaborately clothed with hairs and spines of 
various arrangements, but none are at all like Cliryso- 
corys with its combination of hooked spines, recurved 
hairs, and projecting spiracles. Acantliodactylus has some 
resemblance to it, but it does not go beyond the 
possession of recurved spines on certain segments, not 
in detail at all like those of Clirysocorys. 



136 Dr. T. A. Chapman's notes on Pwpx, 

When we come to the larva, Pteropliorus again presents 
very great variation from a nearly smooth larva to a very 
hairy one, and some species possess hairs with expanded 
tips essentially the same as those of Chrysocorys- ; but 
then such hairs, moderately developed, are found in very 
many families of Lepidoptera. The relations of the 
several tubercles to each other vary a good deal in 
Ptero-plwrus, and, as I read Mr. Dyar's descriptions, 
there are one or two species with tubercles disposed as 
in Chrysocorys, by one and two (trapezoidals) and four 
and five (post ? and subspiracular) being almost united. 

When we come to the egg, PteropJwnis varies again 
here within wide limits, but there is not even a remote 
suggestion of the structure found in Chrysocorys. 

These differences, whilst placing Chrysocorys nearer 
to Ptero'phorus than, say, Orneodes is, hardly admit of its 
being in the same family. 

The peculiar cremaster of PteropJiorus (an anal and 
a forward portion) is paralleled in Elachista, Yjjonymeuta, 
etc., which belong to the same series as Orneodes, but, 
though this may suggest that Pteroj)horus is after all, 
in spite of the small head-pieces, derived from this series, 
it will leave it as far from Orneodes as ever. Further, 
for instance, than Coleophora is from Adela. The great 
difficulty in placing Pteroj)horus anywhere near to 
Orneodes (though still at a considerable distance) or even 
to Chrysocorys, is the extremely reduced condition of the 
dorsal head-plate, so that it seems impossible to derive 
it from the Adelid series at all, even if one starts as low 
down as Mlcropteryx to allow for the divergence. 

Though the true Pyrales preserve (largely) this head- 
piece, its reduced size places a difficulty in deriving them 
from Pyraloids, though there is obviously a long series 
of forms through which the reduction might occur gradu- 
ally. The same difficulty faces an attempt to place any 
macros in this line, but these difficulties in the case of 
the Pyrales and Macros would be shght compared to 
attaching to the series so extreme a divergence so low 
down, as would be the case with Pterophorus. 

Pterojjhorus might certainly fall under my definition 
of a " micro " whose larva is " an exposed feeder,'' and 
Dyar places it there along with Anthrocera and Limacodes, 
and both in structure and habits the larva falls into 
that division as readily as into any other; at any rate 



Orneodes, Epermenia, Chrijsoeonjs, and PteropJiorus. 137 

it is almost certainly not a member of the Adelid series, 
and if it be, it is certainly at a great distance therein 
from Orneodes. 

A point to be especially noted is the extreme divergence 
between the pupa of Pterophorus and that of Pyrales. 

Pyrales have a pupa that is a true macro in dehiscence, 
in possessing segments four and seven (abdominal) fixed 
in both sexes, and possesses no micro characters except 
a dorsal head-piece (a character that goes very high up), 
maxillary palpi, and in some families appendages pro- , 
jecting beyond segment four. 

Pterophorus is a true micro in dehiscence, has segment 
four free, and seven free in male, the dorsal head-piece 
is evanescent, and it has lost the maxillary palpi. 

It is impossible for one of these forms to be derived 
from the other, and impossible for them to have a com- 
mon ancestor higher up in the series than Tinea, more 
probably that ancestor is much lower. 

Orneodes has a pupa of Obtect formula as to free 
segments, and the dehiscence is of very nearly the macro 
type. Antennas separating from head, and eye-covers 
remaining attached to face-piece. It retains one, and only 
one, very marked micro character, viz., the possession of 
a dorsal head-plate ; not only so, but this plate is of 
immense size, whilst the prothorax is correspondingly 
reduced. Contrarily the pupa of Pterophorus retains 
most of the characters of a Tnicro, the one that it has 
almost lost is this head-plate, which is nearly evanescent, 
although it retains the function of carrying the eye- cover 
on dehiscence. 

Both have then been derived from the micro stirps, as 
we know, indeed, that all pupae have been ; but the 
routes have obviously been divided for so long a period 
that it is justifiable to describe them as in nowise related, 
less probably than any two families of macros. 

I present figures of the eggs of the four genera re- 
ferred to in this paper, chiefly on account of the fact that 
whilst those of Orneodes, Epermenia, and Pterophorus, 
present features that ai-e frequent in many different 
families of Lepidoptera, that of Glirysocorys is so unusual. 

The ova of Orneodes and Epermenia belong to the 
section with horizontal micropylar axis and rough sculp- 
turing, characteristic of the stirps we have been consider- 
ing. Pterophorus has a horizontal Q^g, but with 



1'6S Dr. T. A. Chapman's notes on Pwpse, 

sufficiently smooth surface to ^ive some support to the 
idea that it belongs to the Zygtenid stirps; whilst 
Clirysocorys has a vertical micropylar axis, throwing 
doubt on the position in which I have placed it. But the 
whole question of oval forms is too large to treat incident- 
ally in this place. 

I also present figures of the pupa of each genus, and 
also of their dehiscence, and of the remarkable hairs of 
the tubercles of Chrysocorys larva (omitted from plates). 

In regard to the names, it appears that Chauliodiis has 
to drop, but whether Epermenia or Galotripis is to take 
its place, I do not yet know. Nor am I at all satisfied 
that Chrysocorys festaJiella ought not to be called 
SchrecJcensteinia scissella, but I am not trained in that 
line of research that would enable me to settle this 
matter. 

A few details as to each family is appended. 

Orneodes. — The egg laid in the flower-heads of honey- 
suckle is about "48 mm. long and "28 mm. wide, somewhat 
cylindrical and truncate, or like a short thick brick with 
the angles and corners rounded off; the surface is sculp- 
tured with irregular raised lines and pits. 

The young larva has dorsal tubercles arranged trapezoi- 
dally, one supraspiracular, two subspiracular, and two 
marginal, these persist during the life of the caterpillar ; 
the skin is rough, with minute sharp spicules similar to 
those in Epermenia dancellns, and many other larvge. 

The pupa is brown, and noctua-like in general form and 
texture. It has only five and six (abdominal) segments 
free, and has the projecting knob-like head that occurs 
in most of the forms belonging to the series with a narrow 
depressed prothorax and a large dorsal head-piece. 

The size of this dorsal head-plate in this pupa reaches 
the extreme that I have observed, and is, indeed, very 
remarkable. There are no labial or exposed maxillary 
palpi, and the dehiscence is quite macro in character, the 
antennas separating from the face head parts, which 
remain attached to the eye-covers ; the lower parts of the 
appendage covers remain in situ, and are only separated 
at the head. There is a femur case shown, and the second 
leg- reaches the head. The maxilla and first leg- fall 
short, and expose a portion of the third leg, between and 
beyond the second. The appendages project freely over 
the fifth and sixth segments. 



Orneodes, Epermenia, Chrysocorys, and Pterophorus. 139 

The anal armature consists of ten or twelve fine 
spines, little more than hairs, curved and crossing one 
another in lyre shape, and having a fine recurved flattened 
extremity. There is also a small bristle above and below 
each (exposed) abdominal spiracle. 

Epermenia. — The eggs are ovoid, but rather long and 
narrow, being fully twice as long as broad, and rather 
narrower at one end; the surface sculpture is a raised 
network, somewhat irregular, but tending to be hexa- 
gonal, with the cells lengthened in the line of the long 
diameter of the egg. Many are often laid on the same 
leaf; but each egg appears to be laid solitarily, and it 
appears to be, when laid, very soft, as it takes the impress 
of the hairs of the leaf amongst which it is laid, and 
adheres to them very firmly. 

The larva has two dorsal (trapezoidal) tubercles, a 
supraspiracular and a double subspiracular tubercle, one 
marginal, and three ventral (on legless segments). The 
tubercular plates are very large, and that of the supra- 
spiracular in some degree surrounds the spiracle. There 
is a minute tubercle at the anterior margin of the seg- 
ment in line with the posterior trapezoidal. The 
general surface is closely studded with sharp deflexed 
points, as Orneodes. The larva can hardly be called a 
miner, but tends to burrow something after the manner 
of the Procridsi. This is very marked in E. daucellus, very 
slightly so in E. cJicerophylleUus. The resemblance to 
Simxthis appears to be entirely superficial. The pro- 
legs have sixteen hooks set in a circle, but more crowded 
along the inner margin ; the anal pair have eleven or 
twelve hooks. 

In pale brown colour and general outline the pupa 
resembles that of a noctua ; the species I have examined, 
E. daucellus and E. cJioerophyllellus, are very much alike. 
They have the first four abdominal segments fixed, the 
next two free, and the seventh also, in the male ; the 
appendage cases project across the fifth as far as the 
sixth segment, the incision between the fom'th and fifth 
segments is sloping, the fourth segment being narrowed 
and the fifth widened dorsally, ventrally the reverse. 
The large dorsal head-piece and narrow prothorax are 
almost identical with those of Orneodes. The abdominal 
spii-acles are on slight mam mill a3, in very Pyrale manner. 
There are twelve slendei*, very curved, hooked hairs as 



140 Dr. T. A. Chapman's notes on Pupse, 

an anal armature^ seated on the last (nine and ten) seg- 
ment, which has a bulbous base, a pen-like form and two 
deep hollows, one on either side. The maxillas show 
between them a narrow opening with the labial palpi, 
traces of femur between maxilla and first leg, the second 
leg does not reach the head, the third leg is visible 
between lower end of antennae, the second legs falling 
short by about one-seventh of the length of the appen- 
dages, and the maxilla and first legs by about another 
one-seventh ; there is a small maxillary palpus. 

The dehiscence is by splitting down dorsally to, but 
not through, the metathorax ; the mesothorax separates 
half-way down the wings from the metathorax ; the 
antennas separate from the head and for a quarter of this 
length from the wings, but adhere to the second legs, first 
legs, and max. palpi, the face and maxilla separate from 
the antennas and legs, retaining the eye-covers and 
adhering by the maxillary extremities to the rest of the 
case. 

Chkysocoeys. — I obtained larvee, and bred them thirty 
or more years ago, and was under the impression that they 
could be had anywhere or at any time. It disappointed 
me a good deal not to be able to get them during several 
recent years that I have desired to study them afresh. I 
was, therefore, very pleased last March to capture a 
female moth, which very obligingly laid a number of 
eggs. These were laid singly, on either side, on the 
margins, or petioles, of the young leaves of the bramble- 
shoots, with which I had placed the moth for this 
purpose. 

The egg is urceolate in shape, about 0*5 mm. high 
and 0'25 broad, rather narrower upwards, and having a 
hemispherical or flattened base, very much according to 
the situation in which it is laid, the rounded being the 
primary form ; but when laid the egg is soft enough to 
take something of the form of the surface it is laid on, 
and sometimes has a regular flat base of the whole width 
of the egg. The upper end is flat, with a well-defined 
margin, from which arises a structure quite new to me 
in lepidopterous eggs. There is often, in lepidopterous 
eggs, a rim or ridge, or break in the smoothness of the 
surface at this point. The egg of ChoTenfes is, perhaps, 
as good an example of this as any. In Ghrysocorys this 
rim carries fourteen transparent spines with bifid tips. 



Orneocles, Epermenia, Chrysocorys, and Pterophorus. 141 

forming a crown-like circle, and reminding one, in some 
degree, of the similar processes in the ova of some Hemi- 
pitera. The flat surface within these is marked by 
radiating impressions, proceeding from a small central 
micropylar rosette. The outer surface of the egg is 
covered with rather deep, irregular depressions, sepa- 
rated by rounded ridges, which, though irregular, have 
a distinct tendency to be hexagonal, with the longer axes 
of the spaces parallel with that of the egg. To escape, 
the young larva eats out the flat top within the coronet, 
and leaves the egg apparently little damaged. The newly- 
hatched larva is a white or colourless little atom. It is 
possible, however, to observe that the posterior dorsal 
tubercle carries a long smooth hair, directed rather back- 
wards, the tubercle being raised round the base of the 
hair into a high conical projection, and the hair itself 
being longer than the diameter of the larva ; the anterior 
trapezoidal is a much smaller hair, rising in a smaller 
tubercle, situated in the front base of the cone of the 
posterior; the supraspiracular is an equally small hair 
in a moderately-developed tubercle; the subspiracular 
tubercles are a reproduction of the trapezoidal, a large 
posterior hair on a high cone, and a smaller one in front, 
one directed backwards and the other forwards. I have 
not clearly defined the prologs ; the anterior and posterior 
hairs are much longer. 

As the larva grows, the subspiracular hairs retain their 
simple character, but assume the appearance of the tines 
of a pitchfork on a common raised protuberance; the 
dorsal hairs, however, acquire a very special character. 
They continue to be a larger posterior sloping backwards, 
and a shorter anterior lying forwards, their bases are 
almost conjoined, and rise into a distinct peduncle. The 
hairs terminate in a sharp point, but on the upper aspect, 
near the apex, have a lancet-shaped transparent flange ; 
and through the peduncle and down the hair is what 
looks like an inner tube, arising from the internal tissues 
of the larva, and terminating between the flange and 
apex of the hair. There is sometimes fluid at apex of 
hair provided through this tube. The surface of the 
hairs is finely waved or granulated. The spiracles are 
at the apex of a large brown chitinous mammilla. The 
ventral prolegs have a short conical pedicel, a rounded 
boss at apex, carrying six hooks regularly disposed around 



142 Dr. T, A. Chapman^s notes on Pnpw, 

it. The anal prolegs have nine hooks disposed in a 
curved line that is less than a semicircle, the hooks are 
larg^er and stronger than the ventral ones. The true legs 
appear to have four joints before the claw, which is 
accompanied by a transparent, battledore palpus ; the 
antenna is three-jointed, the second joint carrying a long 
hair and a fleshy tubercle, the third carries two terminal 
bodies. 

These larvfB were full-grown by the middle of May ; 
they lived on the upper side of the bramble leaf, spinning 
no silk except a very slight web. When about to moult, 
and when travelling from leaf to leaf, they are very 
sluo-gish in their movements, yet fond of moving occa- 
sionally to a fresh leaf; when at rest the head is rather 
hidden by being withdrawn into the second segment. 
They are of a glassy transparency, and match the colour 
of the bramble leaf very closely, so as to be difficult to 
see. In moulting, the slit appears to be dorsal, and 
the empty skin remains stretched out at length, with the 
head bent under the first segment. The cast skin makes 
a good preparation of the hairs. 

The cocoon is a very remarkable structure, and I 
regret not having seen how it was made. It is attached 
by one margin, naturally probably zo the bramble stem 
near the root, aiid consists of a network of stiff' gum- 
1ike strands of silk, one set of these being in continuous 
lines, like the mortar between consecutive courses of 
brickwork, the other uniting these alternately like the 
vertical lines of mortar between the bricks in each course, 
the bricks being represented by the openings, which are, 
however, square rather than oblong ; the primary strands 
are sometimes, as it were, in one set, from the four sets 
in which they appear to be constructed being accurately 
worked together ; in other cases the four sets are more 
or less distinct, they would be separated by slicing the 
cocoon longitudinally and transversely down on to its 
attached margin. When each side is accurately con- 
structed the courses arch upwards from either end of 
the line of attachment meeting in the line of transverse 
division suggested. There is a valvular longitudinal 
opening at either end, through one of which the larval 
skin is ejected, through the other the pupa emerges for 
the exclusion of the moth. 

The pupa lies free in this cocoon with little spare 



Orneodes, Epermenia, Chrysocorys, and Pterophorus. 143 

space longitudinally, though rather free latitudinally. 
I ought to say that flimsy as the cocoon looks, it is 
really very hard, firm, and elastic. 

The pupa is green Avitli sundry markings, and these 
appear to increase with the age of the pupa, till it be- 
comes very dark. I fear I ill-treated my pupa3, as only 
one emerged, and the rest have, I think, died and dried 
up. I imagined they would all come out very soon, with 
a view to a second brood ; I now think that this is the 
rare exception, and that the pupee lie over the remainder 
of the summer, and possibly the winter, though it is 
perhaps more likely that the insect hibernates as a moth. 

The pupa has a rather prominent globular head, a 
distinct waist (dorsally), the abdominal segments gradu- 
ally tapering and arching forward. The free segments are 
4, 5, 6, ?, and 4, 5, 6, 7, $ , the wing and leg-covers ex- 
tending over the fourth and part of the fifth segments. 

The abdominal spiracles are each in a lofty brown cone, 
very similar to that of the larva, and on either side, 
somewhat dorsally, is on 4, 5, 6, 7, 8, 9, and less 
markedly on o, a hook or spine, dark in colour, curved 
backwards, and ending in a sharp point — behind and 
outside these is a fine hair with recurved curled tips, 
and a similar hair is placed above and another below the 
spiracle ; about ten similar and longer hairs form the anal 
armature. The spiracles have an unusually dorsal posi- 
tion, and there is along interval between the subspiracular 
hair and two ventral ones. Six similar smaller hairs are 
on the face and head, and the mesothorax possesses two 
pairs. There is a minute point which appears to be the 
maxillary palpus, and is carried in dehiscence at the 
extremity of the first leg-piece. The maxillas are 
separated to show the labial palpi broadly, and a portion 
of femur shows between the maxilla and first leg. The 
antennas and second legs extend to end of wing cases, 
the tips of third legs beyond, the maxilla falls a little 
short, and the first legs reach little more than half way. 
The first legs touch the antennas and exclude the second 
from the head. The prothorax is reduced to a very 
narrow strip and the dorsal head-piece is very large. 

The formula of abdominal free segments is the same 
as that of a very large number of the Incompletas, 
Tortrices, Psychids, Sesiids, true Tineids, Cossids, etc., 
so that this does not go far in showing an alliance with 



144 Dr. T. A. Chapman's notes on PiipcT, 

Pterophori whose formula is the same. More important 
as showing a separation is the fact that it preserves the 
habit of emerging from its cocoon before the exclusion 
of the moth; Pteropliorns being fixed by a cremasfcer 
and usually making no cocoon. The great development 
of the dorsal head-piece is another very distinctive 
character ; the dehiscence also is very different. 

The cocoon of the American Penthetria parvula is 
extremely similar, but more regular and elaborate. Its 
pupa retains a very simple tineoid character, so that 
there is no doubt a considerable gap between these two 
forms, but there can be little doubt that the cocoon 
structure has a common ancestry and is not an inde- 
pendent invention. 

Pterophoros. — The ovum is of oval section in every 
direction, a form that may most easily be described as 
that of an ordinary bird's egg, if laid on its side and 
then flattened. The different species I have examined 
vary in their size and in the proportion of their different 
diameters, but all have this general form : they are 
smooth, bright, and polished, and have faint mai'kings 
of a network tending to a hexagonal mesh. 

In some cases the narrowing towards the small end 
is not so evident, and in others {hipunctidacfylns) the 
egg might almost be called cylindrical, so that there is 
considerable variation within definite limits which may, 
of course, be exceeded in species whose eggs I have not 
seen, but I have seen no suggestion of such a form as 
occurs in Chnjsocorys. 

The larva of most of our Pterophori are well known, 
and I don't know of one whose characters are at all like 
those of Ghrysocorys — either as to the retention in all 
stages of the same arrangement of hairs and tubercles, 
or in having at any stage precisely the same arrange- 
-ment as in Ghrysocorys. 

The pupa of Pterophorus is highly specialised, yet 
retains several of the most definite characters of the 
Incomplete. Only the three first abdominal segments 
are fixed, the next three (and four in (? ) are free, the 
antennae and maxillfe adhere to the head-piece and 
separate from the other parts on dehiscence, the eye- 
covers going with the dorsal head-piece. It possesses 
a very special and elaborate set of terminal hooks, by 
which it fixes itself to a pad of silk, these are supple- 



Orneodes, Epennenia, Ghrysocorys, and Pterophorus. 145 

mented by a separate little group on the ventral surface 
of the ninth abdominal segment. The surface of the 
pupa may be very simple and smooth, and its texture 
delicate as in Tinea. It may be covered with a most 
confusing panoply of hairs as in A. spilodactyla, or have 
various elaborate hooks and processes as in A. acantho- 
dactyla. In this case one is reminded, in some degree, 
of the hooks of C. festaliella, but in ^4. acanthodacfyla, 
these hooks are recurved, in G. festaliella they are directed 
simply backwards. Apart from its thorough - going 
retention of micro characters, it is separated not only 
from Orneodes, but from Chrysororys also, by the extreme 
reduction of the dorsal head-piece. So reduced is this, 
that its presence would be doubted in some species, 
but that it carries with it the eye-covers as in typical 
micro dehiscence. 

As a sumniary of the facts and deductions herewith 
presented, I may recapitulate : — 

A correction as to free segments of Limacodidai. 

A correction as to Nolidm not being " macros." 

A suggestion that sundry families of Palesolepidoptera 
may be postulated as having once existed. 

That a series (from below upwards) of families origi- 
nated in MicropteryK, or at any rate in Adelids, 
characterised by a very narrow prothoracic, and a very 
large head-plate in the pupa. 

That E'permenia and Orneodes are typical members of 
this series, and probably also Ghrysocorys. 

That Pterop)liorus is not a member of this series, or, if 
it is, originated very early in it, and reached its 
present position by an undiscovered route. 

That Coleophora belongs to this series, and was derived 
from Adelids by a separate route from Tinea, Eper- 
menia, etc. 

That the Pyraloids (including vaost Tiv eina with Obtect 
pupffi) form a higher part of this series. 

Whether these proceed onward to Pyrales (and 
Geometers) is not fully discussed, and left doubtful.

YII. Descriptions of neio genera and species of Goleoptera 
from South Africa, chiefly from Zamhezia. By 
Louis Peringuey, F.E.S. 

[Read March 4th, ISDG.] 

Family PAUSSIDiE. 

Gen. Padssus, Linn, 

P. arduus, n. sp. 

Red, shining ; head with a long conical tubercle on the vertex, 
anterior part dehiscent, hairless and slightly punctured in the 
posterior part ; club of antennas short, thick, convex on both sides, 
broader than the head, carinate all round, depressed at the base, 
with the outer angle produced in a long, sharp, slightly recurving 
spine, upper posterior margin without any longitudinal im- 
pressions ; prothorax smooth, longer than broad, with a deep trans- 
verse impression reaching from side to side and having a yellow 
pubescent patch at each end, the anterior and posterior part of the 
disk equally broad, the anterior a little more raised than the pos- 
terior, the sides nearly parallel ; elytra elongate, sub-parallel, smooth 
and very closely punctured, the punctures in the anterior part being 
deeper and broader than those behind ; pygidium very closely and 
deeply punctured ; femora not clavate ; tibiae slender, not dilated 
at the tip. Length 8, width 2^ mm. 

Belongs to the same group as P. spinicoxis, P. thomsoni, 
etc. The shape of the club is nearly the same as in the 
last mentioned species, but much more convex on each 
side ; the prothorax resembles that of P. spinicoxis, but 
is less attenuate laterally in the anterior part. 

Hah. Zambezia (Manica). 

P. manicanus, n. sp. 

Reddish-brown, shining ; head much depressed, nearly smooth 
and hairless ; club of antennas twice as long as the head and neck, 
nearly oblong, a little narrower at the apex and base than in the 
middle, compressed but thicker in the median part, bluntly 
carinate all round and with the posterior angle produced in a 
sharp moderately recurved spine : prothorax nearly cordiform, but

150 M. Louis Peringuey on new genera and species of 

very deeply sinuate laterally in the middle, and -with an arcuate 
transverse median narrow and shallow impression ; the anterior 
part of the disk is hardly more raised than the posterior, and 
slightly aculeate in the posterior angle above the constriction, 
when there is also a very small, pubescent, yellow tuft ; elytra 
parallel, deeply and closely punctured, each puncture bearing a 
short seta ; pygidium punctulate and setulose ; femora a little 
swollen, tibiee slender. Length U, width 2^ ram. 

Hah. Zambezia (Salisbury). 

The nearest ally of P. manicaniis is P. planicollis, RafFr., 
from Abyssinia. The shape of the prothorax is identical ; 
the head is equally depressed, but has no trace of a minute 
conical tubercle at the extreme apex; the antennal club is 
of a shape similar to that of the S of P. plauicoUis, but 
not so long, and therefore a little broader in proportion. 

P. r affray I, n. sp. 

Piceous-black, with the apical part of the elytra and the tarsi 
reddish-brown ; head rugulose, with the anterior part deeply im- 
pressed in the centre and the walls of the impression raised in two 
short tuberculif orm processes, posterior part bi-impressed ; club of 
the antenuEe sub-ensiform, very long, compressed, external margin 
with a moderately wide groove reaching from the base to near the 
apex, both margins of the groove very faintly notched ; prothorax 
bi-partite, the anterior part raised, smooth, the median transverse 
cavity wide and deep, and having two pubescent yellow patches in 
the centre, posterior part depressed and with three tuberculated 
indentations ; elytra elongate, sub-parallel, shining, moderately 
punctured, each puncture with a very short greyish hair ; femora 
not thickened ; anterior and intermediate tibiiB slender, posterior 
tibife broadly dilated and flat. Length 5, width H mm. 

Hah. Natal (Frere). 

The shape of the club of the antennee is not' unlike 
that of P. germari ; it is however longer, more curved 
outwardly, and not attenuate at the tip. 

P. concinnus, n. sp. 

Head, prothorax and legs brick-red ; elytra black, edged with 
red at the base and apex ; head and prothorax glabrous, the former 
edged in front on the vertex with a high semicircular ridge, which 



Coleoptera from South Africa. 151 

is broadly emarginate in the middle and reaches from eye to eye, 
posterior part raised above the neck into a ridge higher than the 
anterior one, and with a median and two lateral sinuations ; median 
part of the head plane, and M'ith a broad depression above each 
eye partly edged by a very narrow groove which extends also along 
the posterior raised part ; club of the antenna long, broad, com- 
pressed, as long as the base of the prothorax, slightly curving in the 
inner edge, which is distinctly marginate and has besides a distinct 
raised line running parallel to it, outer margin broadly grooved from 
base to apex, and having seven round alveolse as well as six obtuse 
serrations on the upper edge, the intervals of which bear each a very 
short yellowish seta, outer basal angle of the club long and sharp ; 
prothorax bi-partite, the anterior part much raised, short, abruptly 
truncate, deeply incised in the centre and on each side, and with a 
deep transverse impression ; the posterior part is narrower than the 
anterior, and has the shape of a truncate cone, broadly scooped out, 
in the anterior median part, with each side of the incision produced 
in a sharp, short tubercle ; elytra closely set with very short 
greyish hairs, but very indistinctly punctured ; femora not clavate, 
tibiEe straight, not thickened. Length 6, width 2| mm. 

Hah. Zambezia (Salisbury). 

The shape of the antennal club is that of Pleuropterus 
alternans in general outHne, the impressions on the upper 
side imitating somewhat the articulations of the antennge ; 
the scooped out space of the posterior margin is not 
unlike that of P. hlngl, but the serration of the edges of 
the margin, as well as the impressions on the upper part, 
are very different. 



P. viator., n. sp. 

Piceous-black, with the antennae and legs very dark red ; head 
rugulose and having on the middle of the vertex three short im- 
pressions, the median one of which is the deepest and is bounded 
by two short ridges ; penultimate joint of antennai thick, the club 
short, massive, the inner margin sharp, a little sinuate at the tip, 
the outer one very broadly and deeply scooped out, with the basal 
angle moderately long and sharp, the cavity of the outer margin 
containing six distinct alveolai and the two edges slightly serrulate ; 
prothorax bi-partite, with the anterior part very narrow and in the 
shape of a ridge with a median groove, the median excavation very 
deep, and the lateral part not deeply excised, and with a short blunt

Eah. Natal (Frere). 

Belongs to the group of P. ruber, P. cucullatus, etc. The 
club of the antenuaj is not so broadly scooped out in the 
outer margin as in P. cucullatus, nor is it so much curved 
outwardly ; the upper part is not impressed between the 
inner and posterior margins, and the former is nearly 
straight, not curved, nor is the space between the 
two margins as broad as in either of the above-named 
species. 

P. harheri, n. sp. 

Reddish-brown, with very short pubescence all over ; head with 
two median carinse aculeate in front and overlapping the point 
of insertion of antennae, these two ridges slightly diverging from 
the middle of the vertex and having a narrow groove between, 
ceasing abruptly above the neck, which is very short and not con- 
stricted ; penultimate joint of antennte quadrate, very thick, club 
moderately long, not compressed, deeply sinuate in the inner part 
which, like the rounded apical part, is acutely marginate, outer 
part also sinuate and having ou the margin four very distinct teeth 
bearing several very short setae, while the apical angle is developed 
into a long, broad, blunt spur, the inner part of which curves so as 
to form a short tooth corresponding to a similar tooth situated on 
the opposite part of the base of the club ; the joints of the antennae 
are covered with closely set, very short, squamiform hairs; pro- 
thorax bi-pai'tite, the anterior part in the shape of a ridge slightly 
grooved in the centre, posterior part as broad as the anterior, with 
a broad median depression nearly reaching the base, two pubescent 
patches on the transverse impression ; elytra sub-parallel, covered 
with very short, closely set hairs, apparently thicker than those on 
the prothorax, and without punctures ; pygidium thickly pubescent 
and with a fringe of long, thickly set, yellowish hairs ; anterior 
and intermediate femora and tibi;e slender, posterior femora and 
tibife dilated and compressed. Length 9, width 3| mm. 

Eah. Natal (Durban). 

No known ally ; the nearest approach to the shape of 
the antennal club is in P. bicolor, Raffr., from the Andaman 
Islands, but the incised portion at the inner part of the 
base is absent in that species. 



Coleo'ptera from South Africa. 153 

P. marsliolli, n. sp. 
Reddish-brown, shining, elytra thickly pubescent ; vertex of the 
head nearly plane, posterior part ridged above the neck, and along 
the outer sides ; penultimate joint of antennae quadrate, nearly as 
large as the head, club broad, massive, inner margin carinate, with 
a short, round basal spur not projecting much, outer margin broadly 
hollowed with the edges bi-sinuate, acute at the apical part of the 
hollow, and bearing on each side a dense tuft of long, yellowish 
hairs, basal outer spur very broad and sub-quadrate ; prothorax 
bi-partite, the anterior part compressed in a sharp ridge, slightly 
emarginate in the centre and sub-aculeate laterally, the posterior 
part hollowed anteriorlj', and with a ti-iangular longitudinal groove, 
and the outer sides produced in a carina sinuate in the middle, sharp 
in the anterior part, and with the posterior part forming a long 
tooth standing at an angle with the base, both the points of the 
lateral carina having a distinct tuft of hairs ; elytra short, sub- 
parallel ; pygidium with short pubescence and having in the middle 
three transverse rows of long and very thick bristles ; legs slender, 
anterior femora not thickened. Length 5^, width 2| mm. 

Ilah. Natal (Frere). 

This species belongs to the group of P. laticollis, 
P. penicillatus, and P. rugosus, liaffr., from Abyssinia, 
and are distinguished by having thick stiff bristles on the 
pygidium, as well as tufts of hairs on the apical part of 
the edges of the hollowed outer margins of the antennae. 
'1 he nearest ally of P. marshalli is P. penicillatus, but in 
the antennal club of the former there is no longitudinal 
impression whatever on the upper part along the inner 
margin, nor is the scooped-out space distinctly impressed, 
and the inner edge of the hollow is very deeply sinuate.

the base of the elytra are also similar, but the horn of 
the clypeus is very much shorter, and the elongated 
horizontal process of the prothorax is very different.

Hab. Zambezia (Manica). 

Belongs to the group of 0. curvipes, Lansb. ; tbe 
clypeus is less aculeate in the male, and the general 
facies is a little less convex. As in 0. curvipes the inter- 
mediate tibiae of the S lif^ve an inner lamina, but diffe-

and the anterior part is surmounted by a narrow, but high ridge, 
deeply sinuate in the middle. Length 12-14, width 7-9 mm. 
Hah. Zambezia (Salisbiu-}'). 

This species is allied to 0. lyyramidaUs, Klug ; in 
shape the cephalic horns of the 6 are much thinner, 
more compressed, and spread more outvi^ardly, somewhat 
in the manner of those of 0. rangifer, Klug, but the 
median compressed spine is absent in 0. pyramidalis, the 
thoracic spine is less compressed, and shorter than in the 
last-uamed species, and ends differently. 

0. ponderosus, n. sp. 
Bronze-black, a little lighter in colour on the prothorax ; palpi 
and anteunsj yellow ; clypeus a little elongate in the middle, 
closely plicate transversely, and having in the middle a transverse 
raised line, while the hind margin is produced in a high transverse 
ridge, sinuate in the (J in such a way as to give it the appearance 
of bearing five short blunt tubercles ; prothorax broad, very 
deeply sinuate laterally behind, covered with short granules in

Fairmaire has described in the '' Annales de la

p. 652, a large species from the Congo (French Terri-

be somewhat allied to B. panza, and which, he justly 
remarks, is not unlike some Australian species; he adds, 
however, that the African species are small and without 
" armature,^' by which expression he means, I presume, 
prothoracic horns. I have retained for this species the 
name (in litteris, Dohrn) it bore in Lansberg's collec-

basal joint of the anterior tarsi broadly triangular. In the $ the 
elytra are more convex along the suture, more abruptly dehiscent 
behind, with the lateral granulation less pronounced, and there

M. algoensis, n. sp. 

Black, covered with a light brown tomentum ; head and 
prothorax very closely punctured, hardly ampliate in the middle, 
moderately convex and shortly dehiscent in the anterior part ; 
elytra nearly straight laterally from a very short distance from the 
humeral part, rather plane than convex on the disk, abruptly

retuse behind, the supra-lateral part carinate, the cariua serrulate, 
the disk with a sharp, median smooth ridge on each side, ending 
suddenly at the top of the posterior declivity, the interval between 
the suture and the dorsal ridge smooth, the other interval with an 
indistinct series of very small tubercles. Length 15, width 9 mm. 

Hah. Mozambique (Rikatla). 

Easily distiBguished from all the other described 
South African species of Micrantereus by the smooth 
dorsal ridge ending abruptly at the top of the posterior 
declivity in an acute point, in exactly the same manner 
as in Amiantus carinatus, of the group Molurides. In the 
male the posterior declivity is not so abrupt as in the 
female, and the apical part of the dorsal ridge is, there- 
fore, not so marked ; the tubercles in the interval 
between the median ridge and the supra- lateral part are 
more seriate ; and the intermediate and posterior tibige 
are as much incurved as they are in M. gratiosns, of 
which the present insect may prove to be a variety. 



AcASTUS, n. gen. 

Mentum as in Hoplonijx, Thorns., last joint of maxillary palpi 
secui'iform, labrum transverse, truncate in front, eyes large, 
divided on the vertex by a mere line, supra-antenual crests 
produced in a coalescing semicircular ridge overhanging the anterior 
part of the head ; antennae not reaching the median part of the 
elytra, massive, the joints sub-moniliform, the median ones slightly 
dilated inwardly and somewhat serrate, the apical ones sometimes 
more or less pyrif orm ; prothorax plane, as broad as long, a little 
rounded in front laterally, but wdth the posterior angles very 
sharp, carinate laterally ; elytra sub-oblong, parallel, broader 
than the prothorax, not very convex ; legs moderately long, 
anterior tibiae deeply sinuate at the base, anterior femora wnth a 
broad conical tooth near the apical part. 

Distinguished from Ho2:)lonyx by the shape of the 
antennae, the joints of which are shorter, much more 
massive, the third not longer than the first ; the supra- 
antennal crests are much developed and coalesce in the 
middle.

one, faintly seriate-punctate, and with two round basal costse 
disappearing before they reach the median part. Length 5, 
width 25 mm.

VIII. Descriptions of New Scolytidx from the Indo- 
Malayan and Austro -Malay an Regions. By 
Walter F. H. Blandford, M.A., F.Z.S. 

[Read March 18th, 1896.] 

The purport of this paper is to describe some of the 
moi'e important unrecownized species of Scolytidte from 
the Tropical Old World, which are in my collection. 
Thirty-three new species are distinguished, and of these 
about half were collected by Dr. A. R. Wallace during 
his travels in the Malay Archipelago. It is greatly to be 
regretted that his collections of this family, to which he 
paid some attention, have been broken up before an^ 
opportunity offered of their being dealt with as a whole. 

The Platypodinas were, it is true, described by 
Chapuis, and form no small part of the Old World 
species enumerated in his memoir, but the collections of 
the remaining subfamilies have been scattered, and I have 
been able to examine only the small number of speci- 
mens which passed into the possession of the late Mr. 
Wilson Saunders, and subsequently of myself. No 
attempt has been made to give an exhaustive account of 
that material. Some examples, especially of doubtful 
genera, are in an unfit state for critical examination ; 
while species of Cryphalus and Hypothenemus are best 
dealt with when reviewing those genera, or any con- 
siderable section of them, en masse. 

The wide range of the forms described, from Southern 
India to New Guinea, is to be justified partly by the 
homogeneous character, so far as is known, of the 
Scolytid fauna of the Eastern Tropics, partly by the fact 
that considerable collections of these insects are rarely 
made, and any attempt rigidly to confine descriptive papers 
to the fauna of limited regions must necessarily result 
in the multiplication of small papers, containing each 
descriptions of a very few species, which, though often 
necessary, are certainly inconvenient. 

Among the more interesting novelties, attention may

be called to Platypus plLili-ppinensis, Scolyto-platypus 
eutomoides, Tomicus ])erexiguus, Xylehonis colossus, X. 
glolus, X. scahrijyennis, X. arcticollis, and X. spatulatus, 
all of which present considerable differences from any of 
their known congeners. 



Crossotarsiis cavifrons, sp. n. 

Mas. Elongatus, badius, elytris apice infuscatis ; froute opaca, 
medio impressa ; prothorace oblongo, sparsim punctato, punctis in 
lateribus sulci aggregatis ; elytris punctato-striatis, ad apicem 
declivibus, pilosis, angulis postero-lateralibus productis, depressione 
terminali lunata, subtus juxta suturam utrinque dentata. Long. 
3-6 mm. 

Male, Rather elongate, bright brown, the elytra becoming 
gradually blackish towards apex. Front opaque, impunctate save 
towards the vertex, with a median impression, longitudinally 
sulcate from the vertex to the middle, its sides subcallose opposite 
the antennal insertion ; vertex irregularly punctate on either side 
of the median striga and laterally with one or two deep pits. 
Prothorax a third longer than broad, scantily and irregularly 
punctate, with a series of deep points along the apical margin, 
impunctate over the median area anterior to the long and fine 
sulcus, which has one or two lines of aggregated but not pore-like 
punctures on either side of its anterior half. Elytra punctate- 
striate, the striae impressed as usual at the base, interstices flat 
throughout, the first and alternate interstices with au irregular 
single series of finer punctures from the base, the others im- 
punctate ; apical fourth gradually declivous, convex, coarsely and 
irregularly punctate and shortly setose, not striate or granulate ; 
postero-lateral angles produced downwards and backwards, acute, 
terminal impression lunate, concave, its lower margin with a tooth 
on each side external to the apex of the suture. 

Eah. Gilolo (Wallace). 

Two examples. Although the PlatypodinaB collected 
by Wallace were described by Chapuis, the present form 
appears, for some reason, to have been overlooked ; all 
my other specimens from the Wilson Saunders collection 
have passed through Chapuis's hands and bear his labels. 

It is quite probable that the species here described is 
no more than the other sex of G. indomitus, Chap., taken 
by Wallace in the neighbouring island of Morty. What

has become of the type of that insect I do not know, but 
without it association of the two foi^ms as sexes is im- 
possib'e. If this conjecture be correct, the male offers 
no vahd reason for the separation of the species from the 
Crossotarsi suhdepressi, as conjectured by Chapuis. 

Platypus pihilippinensis, sp. n. 

Mas. Nigro-piceus, nitidus ; fronte plana, dense areolato- 
punctata ; prothorace oblougo ; elytris versus apicem subangus- 
tatis et in processus productis, fortiter punctato-striatis, interstitiis 
planis, similibus ; processu utroque ab altero discrete, longo, acuto, 
postice producto et inferue curvato, in margine superiore dente 
acuto armato. Long. 6-3 mm. 

Male. Pitchy-black, shining, subglabrous. Front flat, rugose 
with very close areolate punctures, finer towards the mouth, their 
interspaces forming a raised reticulum ; vertex with strong sub- 
strigose punctures, the median and lateral smooth spaces evident. 
Prothorax a third longer than broad, the sulcus fine, not reaching 
the base, the punctuation distinct, sparse, rather closer towards the 
middle of the disc but absent along the middle line and the mar- 
gins of the sulcus, strong and close in the hind-angles of the 
emargination and basal border, but not the apical. Elytra with very 
strongly punctured striae, similar at the base, the punctures deep and 
subquadrate, isolated before the middle, then more or less confluent, 
the apical portions of the strise sulcate and curved outwards ; inter- 
.stices flat, shiuing, similar throughout, closely punctate at the base, 
the alternate interstices alone with a series of microscopic points 
throughout, their apical portions much narrowed and subcostate, the 
1st sulcate and split, its outer half curved outwards, the 3rd alone 
seriato-punctate ; apices narrowed, produced backwards and some- 
what downwards into two long acute processes, separated from each 
other by a space nearly as deep as broad and widened from the 
fundus to the apex of the processes, their upper border formed by 
the conjunction of the outer half of the 1st, and 2nd interstices, 
armed about the middle with an acute tooth directed backwards 
and inwards, and thence curved downwards, their lower border 
continuous with the 8th interstice and sinuate at its junction with 
the elytra, their inner face concave, continuous with the declivous 
median terminal portion of the elytra, which is internal to the 
everted half of the 1st interstice, longitudinally convex and rugose- 
Underside and legs concolorous ; abdomen depressed, rugosely 
punctured.

One example. This species differs so much from any 
described Platypus as to be referable to no existing 
division of the genus. Its nearest affinities seem to be 
with the Plat I/pi Chvyuri, or perhaps the P. truncati, of 
which not much is known. The abdomen is depressed 
and ascends somewhat from the base to the apex ; but 
the species does not appear to possess any relationship 
with Crossotarsus, its maxillary structure being that of 
a normal Platypus. Its position in the genus will be 
much clearer when the opposite sex is known. 

Platypus hiuncus, sp. n. 

Linearis ; fronte bilineato-punctata et striga media impressa ; 
prothorace eloiigato ; elytris lineato-punctatis. Long. 2-8 mm. 

Mas. Fusco-testaceus ; elytris posterius inf uscatis, ante 
apicem constrictis, baud declivibus, depressione postica lunata^ 
angulis productis, emarginatione longiore quam latiore, baud 
dentata, ambitu superiore ad suturam transverse. 

Fem. Pallide testacea ; protborace plaga cribriformi angusta, 
elongata, circa sulcum munito : elytris postice infuscatis, depres- 
sione apicali lunata, margine suturali quam margine inferiore 
breviore. 

Linear, tbe front nearly flat, more sbining in the male than the 
female, with a short impressed median striga situate between two 
longitudinal rows of punctures; vertex dull, without a shining 
space, with a few deep punctures. Prothorax a half longer than 
broad, the lateral emargination well-marked. Elytra about twice 
as long as the prothorax, finely lineato-punctate, the interstices 
scarcely visibly punctured. 

Male. Testaceous-brown, the elytra infuscate posteriorly. 
Prothoracic sulcus rather long, with a group of 3 to 5 large 
punctures on each side of its anterior extremity, remainder of 
surface with irregularly mixed large and small punctures, absent 
round the hind part of the sulcus, apex and base narrowly stri- 
gillate. Elytra constricted before the terminal impression, the 
inner rows of punctures stronger, the 2nd, 4th, 6th, interstices 
impressed at the base and furnished with one or two granules ; 
apical impression vertical, irregularly ovate, eraarginate below to 
the middle, the emargination widening above and deeper than 
broad, the fundus biconcave, with prominent margins, transverse 
above at the suture, the apical processes produced downwards and 
backwards, closely approximate at the tip, their outer margin sub- 
angulate. 



Descriptions of New Scolytidse. 195 

Female. Pale testaceous, the head and apex of the elytra in- 
f uscate. Prothorax with a narrow oblong patch of punctures round 
the sulcus, a little stronger in front, remainder of surface finely 
reticulate and feebly punctate. Elytral rows of punctures very 
feeble, 3rd interstice granulate at the base ; apical depression 
lunate, rounded and not sulcate above, the postero-lateral angles 
acute, the inferior margin concave, much longer than the sutui-al 
margin, the fundus subconcave, rugulose and shortly hairy. 

Hah. Sumatra, from tobacco (Grouvelle). 

In spite of the examples having been found in tobacco- 
bales in Paris, there can be no question as to the original 
locality of this little species, one of the smallest of the 
subfamily. The male is distinguished from P. forjicuJa 
and allied species by its size, extreme tenuity, and the 
deep apical emargination, which is narrowed at its mouth 
by the approximation of the postero-lateral angles. The 
female resembles that of P. pallidus, Chap., but is much 
more attenuated, and can be separated by the frontal 
sculpture. 

Scaly to -platypus (Teeniocerus) raja. 
Blandf. Tr. Ent. Soc, 1893, p. 440. 

I have had the opportunity of examining a second 
specimen of the male from the Hope Collection. The ex- 
ample is brownish-black, and is less pilose than the type, 
especially on the head, a distinction which may however 
depend on differences in the length of life of the speci- 
mens; it has the elytral interstices more distinctly 
alternate on the declivity, the second being impressed. 
The characteristic hairs round the spines are present. 
I have been able to examine the prosternum, which 
differs decidedly from that of 8. mikado, in the chiti- 
nous appendages of the prosternal organ. These instead 
of being incurved are widely divaricate, straight, and 
either abruptly bent inwards at the tip or furnished on 
the inner side with a tooth, like the bai'b of a fish- 
hook. 

If, as is probable, this curious genus is rich in species, 
it is evident that the structure of this male organ of 
unknown function is likely to furnish differential charac- 
ters of great value, and its careful examination is there- 
fore indispensable. 



196 Mr. Walter F. H. Blandford's 

Scolyto-platypus {Txniocerus) eutomoides, sp. n. 

Mas. Breviter obloDgus, opacus, fusco-ferrugineus, pedibus 
testaceis, pube quam brevissima flava pruinosus ; fronte ad oculos 
excavata ; prothorace quadrato, angulis posticis acutis, supra rudi, 
vermiculato-rugoso ; ita elytris ad basin, sed ab antica tertia parte 
convexe subglobose declivibus, late subsulcatis, sulcis lineis cari- 
natis postice obliteratis separatis. Long. 3 mm. 

Male. Short, oblong, quite dull, fusco-ferruginous, covered 
with extremely short yellow pubescence, imperceptible unless seen 
sideways. Front impressed and concave to the eyes, with an 
incised line from the vertex to the middle, the pubescence a little 
longer round the upper margin but not strong ; antenna with the 
characters of Tamiocerus, brown-testaqeous, the club infuscate, not 
very elongate, pubescent, with a few long hairs towards the tip. 
Prothorax quadrate, broader than long, the lateral emargination of 
the sides scarcely present, the hind-angles acute, prominent and 
directed outwards, apical border very obtusely rounded, with no 
median emargination : surface dull and finely scabrous with an 
irregular corroded sculpture. Scutellum absent. Elytra a very 
little wider than the prothorax at its base and scarcely longer, 
subtruncate at the base, with very finely elevated margins, the 
shoulders rectangular, but somewhat rounded, the sides exactly 
parallel, the apex rather obtusely rounded ; surface cylindrical for 
rather less than the basal third and sculptured like the prothorax, 
then declivous and convex, the declivity subspherically rounded, 
its upper half with six very shallow wide rough sulci, separated by 
fine carinate lines, obsolete behind, the lower half uniformly 
roughened. Underside concolorous, shortly pubescent, the abdo- 
men dull and rugulose, with the first two segments completely 
connate ; anterior flexed surface of the prothorax wide, proster- 
num with a raised carina crossing the flexed surface and becoming 
more elevated at the tip, below which the anterior margin is pro- 
duced forwards, at its extremity are two short obliquely placed 
lobes, subquadrate, with the outer apical angle rounded and the 
inner acute. Anterior coxs with a pencil of very long thick 
yellow hairs ; anterior tibise coarsely scabrous externally, middle 
and posterior tibias slender ; tarsi slender, elongate, somewhat less 
so than in S. mikado. 

Hah. Celebes. 

The colour, whicli is perhaps that of a somewhat 
immature example, and sculpture give the insect a

certain resemblance to the species of Eutovins or Rliipid^ 
andrus J the main structural characters agree well with 
those of S. mikado, Blandf. I have received two 
specimens from Mr. 0. E. Janson. 



Hylesinus wallacei, sp. n. 

Mas. Oblongo-ovalis, nigro-piceus, opacus ; fronte impressa ; 
protliorace grosse f oveolato-punctato, apice et angulis anticis tuber- 
culatis ; elytris crenato-striatis, interstitiis uniseriatim, ad basin 
modo subirregulariter tuberculatis, et quam minutissime setosis. 
Long. 4' 2 mm. 

Male. Oblong-oval. Head black, opaque, front and rostrum 
widely impressed, subnitid, punctured and with a few minute 
appressed hairs ; mouth reddish ; antennje brown-testaceous, the 
club elongate. Prothorax moderately transverse, widest about the 
base, the hind-angles rounded, the sides gently and regularly 
incurved to th-i apex ; surface regularly and not strongly convex, 
piceous-black, opaque, subglabrous, with large deep foveolate 
punctures, close and in parts confluent ; median impunctate line 
finely elevated behind, anterior margin with a row of tubercles, 
larger on the apical angles, the sides submuricate. Scutellum 
convex, transverse. Elytra twice as long as the prothorax, wider 
at the base, their basal margins crenate and elevated but not 
strongly rounded, the sides curved throughout, obliquely behind 
the middle ; the apex not conjointly rounded ; surface piceous, 
with strong crenately punctured striae ; interstices convex, unise- 
riately tuberculate, the tubercles stronger, closer and transverse at 
the base, smaller and rounder on the declivity, apex of the 2nd 
interstice a little depressed ; elytral pubescence subsquamous, very 
short and difficult to observe. 

Hah. Mysol (Wallace). 

Hylesinus despedus, Walk. 

I must refer to this Ceylonese species, with which I 
have previously identified H. scohipennis, Chap., four 
examples taken by Wallace, in Sarawak, Celebes, 
Batchian, and Dorey in New Guinea, respectively. 
The specimens show some differences, both in the depth 
of the thoracic punctuation and the shape of the pro- 
thorax, which, in all, except the Batchian example, is 
somewhat trapezoidal, with a rather distinct muricate 



198 .Mr. Walter F. H. Blandford's 

tubercle at the anterior angles. In the absence of long 
series, it can only be said that there are no present 
reasons for doubting the substantial identity of all these 
forms ; the differences in the shape of the prothorax 
appear to be sexual, the trapezoidal shape existing in the 
female, although the New Guinea example, apparently a 
male, as its front is impressed, offers some difficulty 
towards the acceptance of this supposition. 

Phloeosinus cribratus, sp. n. 

Fem. (?) Oblongo-obovata, picea, antennis pedibusque ruf escen- 
tibus ; prothorace semielliptico, subglabro, subnitido, fortiter 
punctato, linea media subelevata Itevi ; elytris crenato-striatis, 
interstitiis transverse rugosis, in declivitate, 2° , i^exceptis, seriato- 
tuberculatis et brevissime setosis. Long. 2 mm. 

Female. (?). Oblong-obovate. Head pitchy-black, the front 
shining, rather strongly but not rugosely punctured, above convex, 
with a median tubercle, impressed below and smoother, scantily 
and shortly hairy, the mouth with a very short yellowish fringe ; 
eyes bipartite, the emargination just reaching the posterior border 
of the eye ; antenna yellow-testaceous, normal, the club finely 
and closely pubescent. Prothorax as long as broad, narrowed from 
the base, the sides and apex rounded in a conjoint ellipse, the basal 
border bisinuate, forming an obtuse angle in the middle ; surface 
reddish piceous, shining, subglabrous, strongly but not rugosely 
punctate, the median line smooth, subelevated. Elytra a httle 
wider than the prothorax, and three-fourths longer, their basal 
margins oblique, narrowly elevated and crenate, the sides sinuate 
and subampliated behind, the apex broadly rounded ; surface 
piceous, reddish posteriorly, crenate-striate, the striae deep but not 
wide, siibequal throughout, interstices subconvex, more strongly on 
the declivity, closely and transversely rugulose, with very short uni- 
seriate squamiform bristles (probably from base to apex in fresh 
examples), and behmd the middle with small uniseriate tubercles, 
absent towards the apex of the 2nd and 4th interstices, the bristles 
irregularly biseriate on the apex of the other interstices. Under- 
side and legs rufescent ; 3rd tarsal joint simple. 

Hah. Sumatra, from tobacco (Grouvelle). 

The neai^est ally of this species appears to be P. detersus, 
Chap., from Ceylon, which is very much larger, with 
the prothorax more finely and remotely punctate, the 



Descriptions of New Scolytidx. 199 

interstices less closely rugose, and much more shining. 
The complete division of the eyes in F. crihrains is 
remarkable, but is not of sufficient importance to indicate 
generic separation. 

PhUeosiniis vilis, sp. n. 
Oblongo-ovalis, subdepressus, piceus, elytris rufescentibus, pro- 
thorace longitudine pauUo breviore,antice constricto, apice sat late 
rotundato, dorso punctate, liuea media et plaga in utroque latere 
la3vibus ; elytris punctato-striatis, interstitiis rugis transversis et 
setis brevibus uuiseriatim ornatis, in declivitate tuberculatis. 
Long. 1"5-1"6 mm. 

Mas. Fronte irapressa. 

Oblong oval, somewhat depressed. Head black, rugulose, 
subnitid, very shortly pubescent ; front ( $ ) with a not sharply- 
defined circular impression ; front (?) subconvex ; eyes narrow, 
deeply emarginate : antennce brown-testaceous, the club oval, 
not elongate. Prothorax rather broader than long, widest at 
the base and constricted towards the apex, the sides slightly 
rounded behind and sinuate in front the apex rather broadly 
and obtusely rounded, the base bisinuate, but scarcely pro- 
duced backwards in the middle ; surface piceous, lighter at 
apex, moderately shining, subglabrous, strongly punctured, the 
median line smooth, subelevated throughout, on either side be- 
hind the middle is a subelevated impunctate oblong space external 
to a shallow impression. Scutellum small, rounded, black. 
Elytra as wide as the prothorax, and fully one-half longer, 
their basal margins rounded internally, nearly transverse exter- 
nally, narrowly raised and crenate, the sides parallel, the apex 
broadly rounded ; surface piceous-red, finely punctate-striate, the 
interstices narrow, subconvex, with uniseriate very short bristles 
and transverse raised rugse, weaker at the base, tuberculiform on 
the declivity (a little moi'e strongly in the male), and absent at the 
apex of the second interstice, which is smoother and flatter in the 
male. Underside piceous, moderately strongly punctured ; legs 
brown, the 3rd tarsal joint simple. 

Hah. Sumatra, from tobacco (Grouvelle). 

I have received, from the same source, four or five 
specimens of this insect, one of the smallest species of 
the genus and of the Hylesinides. It is unusual in the 
genus to meet with so little sexual difference in the 
structure of the elytral apex.

Cryptarthrum, g. n. 

Cryphalo affine, discedens prothoracis basi et angulis posticis 
marginatis, dorso baud evidenter asperate : tarsorum articulo 
1" minuto, 2° majore, compresso, 3° parvo. 

Head concealed, not rostrate. Eyes oval, emarginate. Antenna 
witb very sbort 4-jointed funiculus, the three distal joints trans- 
verse, widened apically, club ovate, compressed, the sutures curved 
on the inner, straight on the outer face, and ciliate. Prothorax 
short, much narrowed in front and obtusely subacuniinate at apex, 
the hind-angles and base finely margined, surface without evident 
asperities. Elytra not overlapping the prothorax at base. Anterior 
coxfe contiguous, the prosternal process short. Anterior tibiaj 
widened from base to apex, and obliquely truncate, the upper mar- 
gin sinuate, obsoletely toothed ; middle and posterior tibias with 
the upper margin rounded, serrate. Tarsi short, the 1st joint very 
small, the 2nd rather large, compressed and trigonate, the 3rd small, 
the apical joint not so long as the preceding. 

The single species more nearly resembles a CrypTialus 
than the species of any other genus. The available 
examples were too few to permit of dissection, and the 
examination of the tarsal joints proved unexpectedly 
difficult, as the underside and legs were matted together 
with some adhesive substance, probably derived from the 
food-plant. 

Cryj)tartlirum xvall:erl, sp. n. 

Breviter oblongo-ovale, opacum, pallide fusco-testaceum, pilis 
brevibus flavo-cinereis vestitum, antennis et pedibus testaceo-ferru- 
gineis; prothorace alutaceo-ruguloso, anterius obsolete granulate ; 
elytris dense multipunctatis et seriatim setosis. Long. 1*4-1"6 ram. 

Short oblong-oval, pale fusco-testaceous, dull, with short 
moderately close cinereous-yellow pubescence mingled with 
longer setae. Front darker, impressed, rugulose, thinly hairy ; 
antennae pale ferruginous. Prothorax a half broader than long, 
subbisinuate and finely margined at the base, the margin continued 
along the subacute hind-angles to the middle of the sides, the latter 
rounded throughout, strongly incurved and constricted anteriorly, 
so that the apex appears obtusely augulate in the middle ; surface 
uniformly and not strongly convex from base to apex, alutaceous, 



Descriptions of New Scolytidai. 201 

with close rugulose punctuation, and towards the apex with minute 
scattered granules, the anterior margin crenate, pubescence decum- 
bent except for the scattered sette, and partly concealing the sculp- 
ture. Scutellum scarcely distinguishable. Elytra closely applied at 
base to the prothorax, as wide and about a third longer, the sides 
gently rounded towards the base, more strongly behind, apex 
rounded ; surface slightly rounded to the middle, thence more con- 
vex and decUvous, with very close fine subrugulose punctures, 
bearing short decumbent and sometimes squamiform hairs, the 
punctures of the striae not separable from those of the interstices, 
and with regular uniseriate erect setfe. Underside more deeply 
infuscate, pubescent. Legs ferruginous. 

Hah. Darama I. (J. J. Walker). 

Two examples. The British Museum Collection pre- 
sumably contains others, as it received the first series of 
Mr. Walker's captures. Mr. Walker informs me that 
the insect was found probably in a species of Urostigma 
(a genus alHed to Ficiis) ; this would account for the 
glutinous material which entangled the undei-sides of the 
specimens.

rugosely punctate over the mouth, subnitid towards vertex 
(at least in $), glabrous, mouth fringed with a few short hairs ; 
eyes large, Ijroad oval, little emarginate, coarsely granulate ; 



202 Mr. Walter F. H. Blandford's 

antenniB testaceous yellow, the club suborbicular, broader than 
long, with transverse sutures, the basal joint ample, occupying 
more than half the surface, corneous on both faces. Prothorax 
oblong, parallel-sided behind the middle, slightly narrowed in front, 
broadly and strongly rounded at the apex, hind-angles rounded, the 
base subbisinuate ; surface feebly elevated before the middle, in 
front obliquely and not strongly declivous, asperate with fine 
imbricate rugse, stronger in the male, and with a few fine erect 
hairs towards the apex, behind cylindrical, slightly impressed on 
either side about the middle, moderately shining, with fine but 
evident punctuation, absent over the middle line and a spot on 
either side, interspaces ( ,$ ) smooth, ( $ ) finely reticulate. Scu- 
tellum triangular, shining, infuscate. Elytra about as wide as the 
prothorax and rather more than a third longer, truncate at base, 
with subrectangular shoulders and parallel sides ; surface cylin- 
drical, lineato-punctate, the punctures very minute at the base, 
gradually becoming large and deep towards the declivity, inter- 
stices flat, shining, remotely and microscopically punctate in single 
rows, thinly hairy towards the apex, the 2nd and 4th subelevated 
behind and furnished each on the margin of the declivity with a 
strong acute tooth ((^), a small pointed tubercle ( $ ); apex (,5') not 
narrowed, subcircularly excavate, the excavation limited to the 
posterior fourth, its fuudus concave, shining, very strongly punc- 
tured, with a raised crenate lateral and inferior margin ; apex ( 9 ) 
narrowed, retuse, with a deeply punctured impression on each side 
of the suture, wider below, the sides above callose and bearing 
the two tubercles, inferior margin well-defined but little raised. 
Underside concolorous, very scantily pubescent ; prosternum with 
a distinct antecoxal process ; tibiae very sleuder and weakly-

Two specimens. Widely separated as tWs species is 
by its minute size from the other members of the genus, 
it appears in every respect to be a true Tomicus, and the 
male is not unlike an extremely small and elongate 
T. erosus, Woll. Though the genus PUyogenes, Bedel, 
differs from Tomicus in characters dependent merely on 
degradation and small size, this species cannot well be 
referred to it. It has a most distinct prosternal process, 
and its elytral structure is that of the Onthotomicus 
group.

Dryoccetes taprohamis, sp. n. 

Oblongus, niger, uigro-piceus vel ferruginous, subnitidus, longius 
pilosus; prothorace subovato, per toturn, postice rarius, graiiulato ; 
elytris subtiliter lineato-punctatis, iaterstitiis uniseriatim setosis, 
apice foi'titer declivi, subdeplanato. Long. 3-3'8 mm. 

Oblong, varying in colour from deep ferruginous to black, usually 
black with the elytra piceous, with rather long fine erect fulvous 
pubescence. Front subconvex, impressed over tbe mouth, dull, 
closely aciculate below, punctate above, towards the vertex with a 
median shining elevation, pubescence moderately thick ; eyes 
oblong, with a rather shallow emargination ; antennae ferruginous, 
the club as in I), autographus. Prothorax a little longer than 
broad, forming an incomplete oval, widest about the hinder third, 
the sides behind little rounded, and very slightly constricted in 
front, base truncate, hind-angles obtuse but not rounded, some- 
what distinctly margined above the pleural impression; surface 
regularly convex from base to apex, pilose with erect hairs and 
asperate with elevated granules, weaker behind and replaced along 
tbe hind-margin by punctures, median line smooth, subelevated, 
extending to tbe middle. Scutellum rounded trigonate, smooth, 
shining. Elytra wider than the prothorax at its base and about a 
half longer, exactly truncate at the base, with subrectangular 
shoulders, the sides subparallel to the hinder third, thence 
obliquely incurved; surface subcyliudrical to about the middle, 
or somewhat pulvinate, thence obliquely declivous, and convex 
above, finely hneato-punctate, the punctures shallow, weaker at 
the sides, the two first strise subimpressed, the sutural the more 
distinctly, interstices nearly flat, the inner pair very feebly convex, 
subnitid, with regular single series of erect hairs arising from 
minute elevated points ; declivity flattened from side to side and 
weakly impressed on each side of the suture, obsoletely lineato- 
punctate, the interstitial hairs a little longer. Underside piceous, 
thinly pilose ; legs ferruginous, the tibiae stout, dilated towards the 
apex, and rather strongly serrate.

present. 



204 Mr. Walter F. H. Blandford's 

The tliree following species of Dryoccetes show certain 
divergences from the common type of the genus in the 
shape of the prothorax, which is less elongate than usual, 
being in two of the species nearly semielliptical, and 
tends to become gibbous near the base. This form of 
prothorax, which approaches that of Xyleborus, is not 
associated with other marked differences ; the mentum 
is rather more oblong than usual, and the first joint of 
the labial palpi is very large and tumid, as in Xyleho7'us, 
the second and third being quite minute ; the maxillary 
armature, as is customary in Dryocmtes, is spinous and 
not setose. This latter point appears decisive as to 
placing the species in the present genus rather than in 
Xyleborus, with which they appear to form an osculant 
group. It would be premature to establish a fresh 
genus for them without undertaking a revisional 
examination of the mental structure in other species 
of .Dryoca'tes. 

Dryoccetes rugatus, sp. n. 

Oblongus, niger, parum uitidus, fusco-pilosus, antennis ped- 
ibusque ferrugineis ; pi'othovace vix teque longo quam lato, later- 
ibus et apice conjuuctim semielliptice rotundatis, dorso subfequaliter 
rugoso-asperato ; elytris striato-punctatis, interstitiis rugosis, et 
punctis piliferis confertis uni-vel biseriatim munitis, apice fortiter 
oblique declivi, retuso, rugoso-punctato. Long. 5 ram. 

Oblong, black, little shining, with fine fuscous-yellow pubescence, 
the legs and antennse deep ferruginous. Head shortly subrostrate, 
the front slightly convex, subnitid, closely and rugosely punctured, 
feebly impressed between the eyes, finely carinate over the mouth, 
pubescence not dense, rather long, the mouth fringed ; eyes narrow 
oblong, flat, anteriorly sinuate ; antennal club normal. Prothorax 
scarcely as long as broad, widest before the base, the sides and 
apex conjointly rounded and a little exceeding a half -ellipse, the 
hind-angles obtuse, the base subtruncate ; surface convex from side 
to side, declivous but not strongly convex from the basal limb to 
the apex, pilose with uniformly scattered hairs, short over the 
disc, longer at the sides and apex, and covered with close small im- 
bricate asperities, rather weaker behind, the median line smoother 
and subelevated from the base to the middle, but very indistinct. 
Scutellum rounded triangular, shining. Elytra truncate at the 
base, a little wider than the prothorax and not quite double as long, 



Descriptions of Netu Scohjtidai. 205 

the shoulders rounded rectangular, the sides subparallel, narrowed 
and incurved behind, the apical margins oblique ; surface cylindri- 
cal to the hinder third, thence strongly declivous and subretuse, 
punctui'ed in scarcely impressed rows, the sutural row not deeper, 
the punctures rather large but not conspicuous, owing to the trans- 
verse rngje extending between them on to the interstices, the 
latter scarcely convex, with close piliferous punctures or punctiform 
elevations, in single series, except on the 3rd and 5th interstices, 
where they are iiTegularly biseriate, the hairs fine and short, longer 
at the side-margins ; declivity somewhat flattened, impressed along 
the 2nd interstice, dull, rugosely punctured, not more strongly 
hairy, or tuberculate. Underside black ; tibise strongly serrate. 

Hah. Borneo, Sarawak (Wallace). 

The rugosity of the elytra is a characteristic feature^ 
and one which renders the details of the sculpture hard 
to examine. The head is slightly but still perceptibly 
prolonged in front, although the entire absence of any 
rostrum is supposed to be one of the distinguishing 
features of this and allied genera. 

Dryoccetus sumatranus, sp, n. 

Oblongus, badius, subuitidus, erecte fulvo-setosus ; prothorace 
longitudiue subbreviore, fere semielliptico, anterius tamen sub-

strong erect fulvous hairs. Head large, the front oblong, subconvex, 
closely and rather strongly punctured, subrugose, with scanty long 
pubescence ; eyes oblong-oval, sinuate in front ; antennaj yellow- 
testaceous, normal, outer face of the club spongy apically, with 
nearly straight sutures. Prothorax rather broader than long, widest 
just before the base, the sides and apex conjointly rounded, save

rectangular, the base truncate; surface gibbous and elevated into an 
obtuse transverse nodus at the hinder fourth, anteriorly convex, 
posteriorly declivous from the nodus to the base, thinly pilose, 
asperate with close imbricate rugae, finer posteriorly, and granular, 
especially towards the middle of the base. Scutellum triangular

moderately shining. Elytra truncate at the base, rather wider than 
the prothorax and twice as long, with rectangular shoulders, the 
sides parallel, and not narrowed behind, broadly rounded at the 
apex; surface cylindrical to beyond the hinder third, and impressed 
along the suture, thence subabruptly declivous, with substriate rows 
of large round punctures, separated by transverse elevated rugfe 
continued across the interstices, the latter slightly convex, moder- 
ately shining, with erect hairs, uniseriate on the 2nd and succeeding 
alternate interstices, irregularly biseriate on the others ; declivity 
oblique, subretuse and flattened, the striae less strongly punctured, 
appearing deeper on account of the greater convexity of the 
interstices, the sntural interstice being more and the second less 
elevated, the hairs arising from elevated points. Underside and 
legs testaceous ; the tibia3 strongly dentate, the anterior pair 
subtruncate at apex, the other pairs rounded. 

Hah. Sumatra, Singalang Mts. (Beccari). 

My single specimen has an impression along tlie suture 
from near the base to the summit of the declivity, which 
is rather more rugose ; -but this is perhaps an individual 
feature. The sutural stria is not deeper than the rest, 

Dryocietes gravidus, sp. n.

obtuse, base truncate ; surface gibbous just before the base, the 
elevation not markedly transverse, and, together with the apex, of 
darker colour, thinly pilose, the marginal hairs longer, and granulate, 
the granules weaker along the basal limb, which has an ill- defined 
median smooth line extending to the summit of the elevation.

Scutellura rounded triangular, shining. Elytra wider than the 
prothorax, and nearly twice as long, truncate at base, the humeral 
angles rounded, the sides straight and divergent to the hinder 
third, then broadly incurved to the apex, the margins of the latter 
somewhat oblique and not conjointly rounded ; surface subnitid) 
cylindrico-couvex to behind the middle, thence declivous, darker 
posteriorly, lineato-punctate, the punctures moderately fine and 
not easily distinguishable from those of the almost flat interstices, 
which are punctured irregularly in alternate single and double 
rows ; apex less flattened than in the preceding species, strongly 
declivous, slightly impressed on each side of the suture, obsoletely 
punctured, the interstices feebly convex, with minute piliferous 
points. Underside concolorous, tibiae strongly serrate. 

Hah. Borneo, Sarawak (Wallace). 

JBoth my specimens have lost the antennal clubs ; those 
of one example disappeared in process of cleaning, but 
not before I had been able to observe that they were 
of Dryocoites-l'ik.e character. The shape of the prothorax 
is similar to tbat of D. sumatranus, but the species is 
rather more depressed, widened behind, with the hairs 
much finer and the punctures on the elytra fine and 
ill-marked, so that the surface appears at first sight to 
be tolerably closely and confusedly punctate.

claws toothed at the base. 

Hah. New Guinea, Humboldt Bay (Doherty). 

This species, of which I have seen no second example, 
is by far the largest of the genus, and in bulk of all the 
Tomicidte yet known, though it is exceeded shghtly in 
length by one or two species of Amphicranus, and 
perhaps by exceptionally large individuals of some 
species of Tomicus.

In tliis species the encroachment of the declivous rctuse 
surface so often found in Xi/lehortts on to the horizontal 
portion of the elytra is carried to its very furthest limits, 
the latter being practically nonexistent. Described from 
one example; there is another in the British Museum 
Collection.

from it and the following species by the distinct stria3

Hah. Sumatra, from tobacco (Grouvelle). 

A near ally of X. semiojDants, Eiclih., which it closely 
resembles in colour and sculpture. Jt is a rather smaller 
insect, and is best distinguished by the much shorter 
elytra, which are barely one-third longer than the pro- 
thorax, and present, when viewed from the side, a 
uniform dorsal curvature from base to tip ; in X. semi- 
opacus the elytra are rather more than a half longer than 
the prothorax, and are nearly cylindrical to behind the 
middle, and not uniformly curved from base to apex. In 
X. semigranosus the prothorax is longer in proportion to 
its width, and is less ample before the middle ; the 
elytral punctuation is finer and the traces of the strias 
are even more indistinct than in its congener. My 
type has a short impressed line on the base of the pro- 
thorax anterior to the scutellum, but this may be an indi- 
vidual characteristic.

Intimately allied to X. fornicafns, from wliicli at first 
I was unable to sepai'ate it. Having* now seen both tlie 
type and a long series of the latter species, I am able 
to distinguish betvpeen them. The present species is 
rather larg-er and broader than its ally, with the elytra 
relatively rather shorter; the prothorax is widest at the 
base, and the sides quite regularly rounded to the apex, 
while in X. fornicatns the thorax is as wide at the 
anterior third as at the base, and the sides are more 
parallel. X. xantJiojnis, another allied species, has the 
elytra relatively longer than those of X. fornicaius, and 
the prothorax more nearly orbicular.

I have received a fair series of this species, parlly 
from the Indian Museum, Calcutta, partly from Mr. E. 
Ernest Green, and have been able to compare the female 
with Eichhoff's type. The insect has lately made itself 
conspicuous in Ceylon as a destroyer of the tea-plant. 
Some twigs accompanying the specimens are about a 
quarter of an inch in diameter, and show several rami- 
fying burrows, similar to those made by X. dlt<]jar, 
without any very special features. The diameter of the 
holes, an important point in diagnosis of these injuries, 
is about \l-\'2 mm.

Evidently related to K. pelliculosus, Eichli., and like 
that insect, with the prothorax of the type of his

pulvinate, more strongly punctate as well as granulate, 
and not impressed at apex.

Hah. Borneo, Sarawak (Wallace) ; Sumatra, from 
tobacco (Grouvelle). 

The shape of the prothorax differs a little in my two 
examples, being more uniformly curved from base to apex 
in that from Borneo, whereas the Sumatra specimen has 
a slight apical constrictiou. The species, though quite 
peculiar in sculpture for a Xylehorus, and somewhat sug- 
gesting a Hijlocurus, is normal in generic characters, and 
is related to X.. iniheridus, of which the elytral sculpture 
is destitute of the coarse tubercles marginiug the decli- 
vity in the present species.

an arcuate impression below the vertex, rather closely punctured, 
and with the carina replaced by a non-elevated smooth line ; 
vertex opaque, impunctate ; eyes small, ' emarginate ; mandibles 
very prominent ; antennae brown-testaceous, normal. Prothorax 
fully one-half longer than wide, constricted behind the middle, 
thence ampliated, and widest behind the apex, the anterior angles 
broadly rounded with the outer parts of the apical mai'gin, which is 
almost bilobed, being separately rounded on either side with a very 
shallow median indentation, hiud-angles broadly rounded, the base 
truncate in the middle ; surface moderately convex from side to 
side, depressed longitudinally and (in side view) appearing flat 
from just before the base to the anterior fourth, where it becomes 
declivous and convex, apical margin tubercnlate, the anterior half 
asperate with rather coarse granules, and pilose with fine erect 
hairs, posterior half moderately shining, more thinly hairy, weakly 
punctured, the punctures closer in front than at the base, which is 
somewhat calloseh^ thickened. Scutellnm minute. Elytra as wide 
as the prothorax, but scarcely so long, subparallel sided, not 
narrowed behind, and broadly rounded at the apex ; cylindrico- 
convex to the middle, thence convexly declivous, coriaceous, finely 
and confusedly punctured and moderately densely clothed with 
fine hairs ; declivity rugulose, obsoletely striate, not margined 
below. Coxae and underside, except the abdomen, darker, thinly 
hairy ; the latter short. Legs ferruginous, the knees and tibiai 
darker ; femora very stout, inflated ; tibia; rounded externally, the 
anterior pair narrow, weakly armed, the remaining pairs dilated in 
the middle, and more strongly serrate above ; tarsi very long, the 
first three joints somewhat stout and compressed. 

Hab. Sumatra, from tobacco (Grouvelle). 

This form is one of the most singular among the many 
remarkable male forms of the genus. The great length 
of the prothorax, and its peculiar shape, are quite 
characteristic ; its apical indentation is only such as 
results from the conjunction of the two curves formed by 
the independently rounded sides of the anterior margin, 
and there is no dorsal sulcus leading to it. In spite of 
its great length, the prothorax is not, as in many males, 
produced into a peak in front of the head.

before the discal elevation, the sides and apex of the elytra darker. 
Front somewhat flattened, subimpressed on either side over the 
mouth, rather strongly punctured, pilose ; eyes not large, reniform ; 
antennae testaceous, normal. Prothorax broader than long, semi-oval, 
widest behind, the sides and apex conjointly rounded, hind-augles ob- 
tusely rounded, the base slightly curved; surface transversely gibbous 
behind the middle, strongly convex from side to side, pubescent with 
extremely short appressed hairs, anteriorly rough with an admixture 
of granules and rather remote larger transverse rugiB, posteriorly 
closely and strongly punctate with a smooth median line. Scutellum 
rather large, rounded trigonate, shining. Elytra wider at the base ' 
than the prothorax, and nearly double as long, the sides gently 
curved throughout, widest behiud the base, subangulately inflexed 
at apex, the hind-margins obliquely rounded ; surface rather 
depressed from side to side, convex and pulvinate from the base to 
the middle, thence obliquely declivous, rather indistinctly lineato- 
puuctate, the interstices multipuuctate, the punctures bearing 
small appressed hairs and a few short erect bristles in irregular 
rows ; declivity broadly impressed and subexplauate at apex, with 
the suture elevated, the sides of the impression oblique and 
somewhat tumid above, and the inferior margin acute, more 
clearly striate. Underside testaceous, shining and thinly 
pubescent, sides of the elytra deeply inflexed towards the apex. 
Legs brown-testaceous, the tibiee strongly dentate. 

Hah. Borneo, Sarawak (Wallace). 

The very short and nearly hemispherical prothorax, the 
broad and somewhat depressed elytra, and the complete 
absence of armature give the insect an appearance unlike 
that of any described species of the genus. I have, 
however, dissected the mouth parts of one of my two 
examples, and cannot find in them or in other details of 
structure, sufficient grounds for its. removal. The malar 
armature is fine and setiform.

IX. Notes on Dyscrltlna longisetosa, Westvv. By 
E. Ernest Green, F.E.S. 

[Read March 18th, 1896.] 

The accompanying figures represent what I suppose to 
be a more advanced stage of the interesting little insect 
described by the late Prof. Westwood, under the name of 
Dyscritina longisetosa (Trans. Ent. Soc. Lond., 1881, 
p. 601, pi. xxii., fig. 1). 

My example of the insect is rather darker coloured 
than the type, the whole of the upper parts being dark 
reddish-brown, without any pale bands on the abdomen ; 
it has, however, the two small pale patches on the 
posterior angles of the prothorax ; and there is a pale 
median line bisecting each of the thoracic tergites longi- 
tudinally, which is carried forwards to the middle of the 
head, where it bifurcates, the branches turning sharply 
off to a point on the margin immediately in front of the 
eyes. 

Westwood does not definitely state the dimensions of 
his insect ; but gives 8 lines as the length of the caudal 
filaments, remarking that these are " nearly three times 
the length of the entire insect." In his figure, however, 
he gives a scale, indicating the lengths of the parts, by 
which I find that the body is 6 mm. long, and each 
filament 17 mm. In my specimen these proportions are 
considerably altered, the body being 8 mm. long, while 
the caudal appendages attain a length of only 6,^ mm. 

In Westwood's description these caudal appendages 
are said to be composed of more than fifty minute articu- 
lations. In the present specimen, the two appendages, 
though nearly of equal length, consist of a different 
number of joints, there being seventeen in one and twelve 
only in the other. I at first thought that they might be 
imperfect ; but a careful examination of the extremities 
shows a natural rounded termination quite unlike the 
apices of the preceding joints. There is a very long basal 
joint, about equal to the subsequent six ; the remaining 

TRANS. ENT. SOC. LOND. 1896. — PART IT. (jUNE.) 



230 



Mr. E. Ernest Green on 



joints are subequal in length, but gradually diminisli in 

thickness. The ap- 
pendages are finely 
setose, and there 
are a few stout 
spines on the basal 
and following six 
or seven joints. 

The antennaj have 
undergone very 
little change. They 
still contain fifteen 
joints ; but the 
second isvery small 
and sunk into the 
apex of the large 
basal piece, which 
bears several stout 
spines. 

There is an im- 
portant change in 
the structure of the 
'legs, three joints 
being now appa- 
rent in the tarsi ; 
the second joint, 
is, however, very 
small, and firmly 
fixed to the pre- 
ceding one, the line 
of separation being 
rather inconspicu- 
ous. The femora 
are distinctly chan- 
nelled for the re- 
ception of the tibiae. 
There is no pad 
between the claws. 

The mouth parts, 
as far as can be 
seen without dis- 
section, are as de- 
scribed by Prof. 
Westwood ; the 
maxillj© are perhaps rather longer and more falcate.

The similarity of structure to that of the Forficulidai 
is most marked in the specimen under examination. On 
each of two tergal plates, near the base of the abdomen, 
appear a pair of well-marked glandular folds, correspond- 
ing with the scent-glands found in a similar situation in 
many earwigs. On the ventral surface, the sternal plates 
of the thorax are very large and broad, each projecting 
backwards, and covering part of the following segment. 
The legs are widely Separated, and the cox^ small and 
cylindrical. The tergal and sternal plates of the abdo- 
men are fitted together in the imbricating fashion which 
is almost peculiar to the ForficuUdx. The extremity 
of the abdomen, between the cerci, is closed by a 
vertical plate divided transversely into two or more 
pieces. 

The specimen from which the above notes were taken, 
is now deposited in the Natural History Museum, Crom- 
well Road. Westwood's type of the insect is presumably 
in the Oxford Museum.

X. On the Courtsh/ip of certain European AerldiUlff.. 
By Professor Edward B. Poulton, M.A., F.E.S., 
F.L.S., etc. 

[Read April 1st, 189G.] 

The extraordinarily fine and hot weather in Switzerland 
at the end of August and beginning of September last 
year (18y5), was very favourable for the observations 
which are here recorded. I was then staying at the 
VVeisshorn Hotel, high above Vissoye, in the Val 
d'Anniviers, 7G90 feet in elevation. Certain species of 
Acridiida3 were excessively abundant in the immediate 
neighbourhood of the hotel, species moreover which 
afforded examples of very different methods of courtship. 
In working at this subject I received the greatest 
assistance from m}' two friends. Mi-. F. Jenkinson and 
Mr. F. Y. Dickins : their keen powers of observation 
enabled me to add many new facts of much interest, and 
also afforded vahiable confirmation upon the most diffi- 
cult points. Mr. Jenkinson observed with me for hours 
together on several occasions, so that we were able to 
compare our impressions as we received them. 

Dr. Sharp has kindly identified the species for me, 
comparing my specimens with a Brnnner collection at 
Cambridge. 

The object of this enquiry was to make out the 
methods employed by the males in the courtship of the 
females, and especially the part played by stridulation. 
Dr. Sharp, in the Cambridge Natural History (Vol. v., 
p. 286), insists on the insufficiency of observations on this 
point, and I therefore hope that this work has not been in 
vain. The following observations suggest that the true 
sicrnificance of the latter is to be found in its use durino- 
courtship. In only a single species of those observed, 
Stethophyma fuscum, did the males commonly stridulate 
without reference to the females, and merely in rivalry 
with each other. In all the other sound-producing species 
the power seemed, almost without exception, to be 

TEANS. KKT. SOC. LOND. 189G. PART II. (jDNE.) 10 



234 Professor Edward B. Poulton on the 

exercised with direct reference to females, or in rivalry 
to other males in the presence of a female. In the case 
of Psophiis stridulus, true stridulation was only observed 
when the close proximity of a female had evidently 
thrown the male into a state of excitement. 

The I'ollowing considerations also support the same 
conclusions. In Pezotettix pedestris, both sexes have 
rudimentary wings and the male never makes any audible 
sound. Nevertheless, when he is seated on the back of 
the female attempting to pair, and during coitus itself, 
he continually moves his third legs alternately as if 
in stridulation. I believe that this movement is a vestige 
of an ancient and long-lost power of producing sound. 
Although stridulation is usually produced by a symmetincal 
movement of the third legs, it will be shown that this is 
not the case with Stenohothrus elegans. There is there- 
fore no objection to be raised against this character of 
the movement in Pezotettix. Another view, and that 
held by my friend, the learned Orthopterist, Henri de 
Saussure, is that sound is really produced, only we cannot 
hear it. He holds that the sound is merely the outward 
expression of the elated feelings of the male Pezotettix. 

Dv. Sharp, too, considers from the presence in 
apparently dumb species of well-developed tympana — 
and this is their condition in Pezotettix — "that the 
Orthoptera provided with acoustic organs, and which we 
consider dumb, are not really so,, but produce sounds we 
cannot hear, and do so in some manner unknown to us ^' 
(Cambridge Natural History, Vol. v., 287). On the 
other hand, it may be urged that the perception of vibra- 
tion by means of tympana may be of great value in the 
life of an organism, even if the organism were incapable 
of producing sounds, and that it may be retained for 
some more general use v^'hen its original special function 
has ceased to exist. 

But in any case this movement of Pezotettix is con- 
ducted with an apparatus homologous with that by which 
sound is produced in other AcridiidcT, and yet one in 
which the special sound-producing structures are absent. 
The tegmina are too short to be brought into their usual 
relation with the femora, and the ridge on the inner face 
of the latter is without the "musical beads,^^ although 
strongly chitinized and prominent as though it had pi'e- 
viously possessed significance in this respect. 



Courtsliii) of certain European Acridiidse. 235 

Further evidence in support of this explanation is to 
be found in the fact that Pezotettix makes the movement 
when he has succeeded in capturing* the female and wheu 
pairing has actually begun. In the other species ob- 
served the normal arrangement was for the male to 
stridulate apparently to charm or please the female before 
leaping on her; stridulation after this occurring only in 
certain special cases (one observation on 8tenobothrus 
hmmorrlioidalis, and one on Stethopliyma fuscum, in 
which it is to be explained as an answer to another 
very persistent male). 

If, however, as I suppose, the movements of Pezotettix 
are merely vestigial, we can quite understand their asso- 
ciation in the nervous system with those stronger nervous 
impulses which are concerned with the successful issue 
of courtship, rather than with the impulses concerned 
with courtship itself. According to this view the 
functional stridulation is associated with anticipation 
while the vestigial stridulation is only evoked by realiza- 
tion. It should be added that it is quite possible that 
these movements of the male Pezotettix may have a 
stimulating or perhaps merely a soothing effect on the 
female. 

The comparison between Pezotettix and the other 
species supports in another way these conclusions as 
to the essential significance of stridulation in courtship. 
In the latter kinds, so far as they were sufficiently 
observed, the female was treated with considerable cere- 
mony ; in Gom2:)liocerus a peculiar attitude was assumed, 
movement of some of the appendages of the head was 
made, and the female was in some cases patted or stroked, 
in addition to the most assiduous stridulation. The latter 
was never omitted in any species in which we could detect 
any sound. But the little male of Pezotettix, being appa- 
rently without any power of charming the female, behaves 
in a manner entirely different from any of the others 
described below. He lies in wait, leaps on the female, 
and captures her unawares. Then, when he is firmly 
seated,, the male attempts to charm her by nibbling with 
his mandibles, and perhaps by the effect of the alternate 
movement of his third legs. 

The general impression left by the whole of the obser- 
vations recorded below was favourable to the theory of 
sexual selection, and to the view that the stridnlating 



236 Professor Edward B. Poultou on the 

apparatus lias been evolved by the a<rency of tliis 
principle rather than by that of natural selection. 

Others may draw opposite conclusions from the same 
observations, which I therefore set forth by themselves, 
apart from general theoretical considei^ations. I believe 
that the observations themselves are correct, and that the 
uncertain points are stated with due caution. 



Pezotettix pedestris. 

August 29, 1895. — I watched a pair of Pe;:oleliix 
2')€destris continuously for about an hour and a quarter, 
viz , from about 2.30 p.m. to 3.45. The day was fine and 
the sun powerful, and this had been the case for many 
days previous to the 29th. 

When first observed, the male was seated on the back 
of the female, the anterior legs being clasped round her 
prothorax, but every now and then one of them was 
passed round her head and sometimes even over the eye. 
Twice the female was seen to raise her leg and sweep the 
male's leg off her face. The male's second pair of legs 
apparently clasped the posterior part of her first 
abdominal segment, fitting in between the femora of 
the female's third pair of legs and her body. The male's 
third pair of legs were not used for maintaining his 
position, but were held either horizontally or inclining 
upwards postei-iorly, the tibias forming an acute angle 
with the femora, and the tarsus being raised so as to form 
an acute angle with the tibiaj. For nearly the whole of 
the time of observation the male's third legs were jerked 
lip and down alternately, the strokes not succeeding each 
other very rapidly. No audible sound was produced. 
No corresponding movement was seen on the part of the 
female. 

In attempting to copulate, the male let himself down, 
sometimes on one side and sometimes on the other, suffi- 
ciently far to bring the extremity of the abdomen below 
that of the female. The terminal segments of the male's 
abdomen were then turned upwards and inwards towards 
the external generative aperture of the female, with which 
the everted male organs were brought into contact. No 
movement of the corresponding female parts was seen, 
but contractions of the whole abdomen occasionally took 



Gourtshi]) of certain European Acridildx. 237 

place. In the above-described attitude the hold of the 
male appeared to be very precarious, and it seemed that 
he would have been shaken off by a comparatively slight 
movement on the part of the female. 

During the second half of the period of observation, the 
male made more frequent and vigorous attempts, and. I 
noticed that from time to time he gently nibbled the 
female with his mandibles in the dorsal and upper part of 
the lateral thoracic regions. The female, however, 
appeared to be entirely indifferent to his attentions ; and 
sometimes when the male was making the most energetic 
attempts she would calmly begin to eat the leaf of a 
plant. On two occasions she finished, or nearly finished, 
a small leaf, and many times nibbled parts of leaves. 
Although she seemed to prefer the green leaves, she 
sometimes ate portions of brown ones. Five times the 
female ejected fteces ; once I thought the male did so, 
buu it may merely have been getting rid of some foreign 
particle which had accidentally adhered. In the case of 
the female there was no doubt. 

Although the female did not attempt to get rid of the 
male, she showed her indifference to his presence not 
only in the manner already described, but by walking and 
hopping about, often at the most inconvenient times. By 
3.45 copulation had not commenced, and I could wait 
no longer. 13oth insects were then captured for 
identification. 

All the observatioDS recorded above were made quite 
close to the insects. By keeping as still as possible, 
and moving very gently when it was necessary to 
follow them, it was easy to bring the eyes within six or 
eight inches of the insects Avithout disturbing them 
at all. 

August 30. — I saw many of the same species in copula 
beside the upper road, or rather path, leading from the 
Weisshorn Hotel to Zinai. The terminal segments of the 
male's abdomen are turned upwards, in the position indi- 
cated by the attempts already described. The alternate 
movements of the third legs continue from time to time 
during coitus : in one case (which may have been the 
begiuning of copulation) a female was seen to stretch out 
the third legs from time to time, and make a rapid 
shivering movement. With the above exception, the 
female hopped and walked about freely during the pro- 



238 Professor Edward B. Poulton on the 

cess, the male being apparently firmly seated on her 
back. 

August 31. — A pair were found in copula in the Alpine 
garden close to the Weisshorn Hotel. The female was 
seen to eat freely^ and once to void excreta, while the 
male was actively moving his third legs. This observa- 
tion was confirmed by F. Jenkinson. These remarkable 
alternate movements of the male's third legs during 
coitus were also seen by F. Jenkinson and me in a very 
large number of cases at other times. In a single case 
observed by F. Jenkinson on August 31, the male's legs 
were at one time rapidly vibrated laterally, being moved 
simultaneously and not alternately, as in the usual move- 
ment. This perhaps correspoods to the shivering move- 
ment seen by me in the female on August 30th. 

September 1. — This latter observation was confirmed 
by me in the Alpine garden. In this case the beginning 
of the act was seen. The male appeared to be much 
excited, and the shivering movement occurred from time 
to time, just before and after the beginning of the act. 
The female, which possessed only one leg of the third 
pair, was quite motionless throughout. At the com- 
mencement of the act she expelled faeces, which were 
moist and quite different from the dry ejecta seen on 
other occasions. In this and the complete passivity of 
the female there is probable evidence that she was much 
influenced by the act. This passive appearance was 
entirely distinct from the indifference manifested in so 
many of the cases previously observed, in which, how- 
ever, the act had either not begun, or was probably far 
advanced. Shortly after coitus the pair remained motion- 
less for a considerable time. 

September 2. — Up to this date the events immediately 
preceding pairing, and the pairing itself had been observed 
with care, but there was no evidence to show how the 
male became seated on the back of the female. I was 
very anxious to find out how this occurred, and whether 
there was any preliminary courtship by stridulation or 
otherwise, although the species had never been heard to 
stridulate. At this date, F. Jenkinson observed, and I 
was able to confirm, that the males leap upon the females 
when they come within a distance of about three inches, 
but apparently do not notice them at a much greater 
distance. Their attention appears to be directed to the 



ConrtshijJ of certain I^urojJeun Acridiuhe. 239 

female by its movement, and they then leap with the 
greatest accuracy F. Jenkinson obtained these results 
by inducing captured females to leap from his hand in 
the direction of a male. On one occasion ho saw a male 
approach and leap upon another male, probably mistaking 
it for a female ; there was a tussle, in which one appeared 
to try to bite the other. It thus appeared evident that 
there is no prelitninaiy courtship of any kind, but that 
the male takes the female by surprise, and leaps upon her 
before she is aware of his presence. This conclusion was 
abundantly confirmed later on. 

September 3. — F. Jenkinson and I observed a pair on 
the grassy slopes below the Bella Tola. The male had 
lost one of the legs of the third pair, and the female had 
one of them apparently injuret). The male was seated on 
the back ot" the female, and v/as energetically attempting 
to copulate much too far forward in the middle ventral line. 
We watched his continual attempts for about fifteen 
minutes, at the end of which period he was no nearer to 
success than at the beginning. This failure, when the 
female was evidently ready, and kept opening the gene- 
rative oriBce, may have been due to the absence of the 
leg. Although this limb is not used to hold firmly, the 
absence of it may have afiected his balance. At any 
rate no failure of this kind was seen on any other 
occasion. 

Later on, about the middle of the day, we came to a 
flat piece of ground covered with scanty grass, at the 
bottom of the zigzags by which the Bella Tola is ascended. 
The strong sun and the position of the ground made the 
place extremely hot, and as both sexes of the Pezotettix 
were very abundant^ it appeared a good opportunity for 
observing the pairing habits. The males were often 
seated on stones, or other slight eminences ; thus placed, 
and with the head and anterior part of the body raised, 
they were in a very favourable position to see and leap 
upon any female which approached within three inches, 
or sometimes even a greater distance. If the leap is a 
failure, the male at once begins an active pursuit, leap- 
ing more quickly and further than the female. In this 
way it often happens that he loses sight of the latter, or, 
is brought nearer to another female, whom he at once 
attempts to captui-e. One main cause of failure in the 
pursuit is that the male has very little, if any, power of 



240 Professor Edward B. Poulton on ilie 

seeing a female between his leaps, unless his attention has 
been directed to her by the movement of the leap itself. 
Hence the pauses, often greatly prolonged, between the 
successive leaps frequently lead to the escape of the 
female. Furthermore, the leaps made by the male, when 
lying in wait for the female, were much better aimed 
than those made in pursuit. It is probable that in the 
former case he takes very careful aim ; for he turns his 
head and antennie in the exact direction of the female, 
and pauses before leaping, often making a slight rocking 
movement of the anterior part of the body. Occasionally 
this movement was seen in the female also. 

When the male leaps upon her unawares, as I have 
described, the female almost invariably tries to throw 
him off, and generally succeeds. If, however, she failed 
in the first attempt, in most cases she yielded forthwith, 
and, probably as a result of these favourable conditions as 
regards tempe.'ature, pairing was effected in a very short 
time, sometimes even in a few seconds. 

In one instance a male leaped upon a female and was 
thrown off"; the female was then driven round, so that in 
a few minutes she again came within the range of his 
leap. The second time he was successful, securing a 
fii-m hold, and beginning to nibble the female with his 
mandibles. All resistance ceased, and pairing took place 
in a few minutes. 

Very occasionally the alternate strokes, but only once 
or twice repeated, of the male^s third legs were seen when 
the opposite sexes were near together. I believe, too, 
that the same movement was made by the female, though 
still more rarely. One female, when near to a male, 
seemed to be excited, and raised her third legs, which 
quivered from time to time. Any such indications wore 
very rare in the female. In nearly all cases she was taken 
by surprise, and only yielded when very firmly held. 

The female must be influenced in some way by the 
male holding her and caressing her with his mandibles ; 
for his position, when attempting to copulate, is very 
precarious, and he could be easily shaken off. It appeared, 
however, that the males did not begin to make any such 
attempts until the females had ceased to resist. 

In one single instance the female did not yield, 
although very firmly held ; but it is probable that she 
was immature, or injured, or in some way unfit for pair- 



Courtship of certain European AcridiidK. 241 

ing, as the male finally left liei" of his own accord. This 
observation was made by both of us, and was of g'reat 
interest. When we first saw them, the male was firmly 
holding the female, but she kept struggling violently, 
and trying to kick him ofi" with her powerful third legs. 
On at least three separate occasions the pair rolled over, 
and remained in this position, with the male beneath, 
for about half a minute. At such times the female was 
unable to struggle at all successfullj^, and. it seemed 
possible that the male, when he was nearly unseated, 
caused the pair to roll over ; we could not, however, bo 
sure of this. Ultimately the male leaped off voluntarily, 
as I have already stated. One side of the dorsal surface 
of an abdominal segment was wounded in the female, but 
as the injury did not appear to be fresh, it is not probable 
that the male caused it. 

In one or two cases the female, and once the male, 
expelled faeces just before or during copulation. The 
faeces were of the character already described, and not in 
the usual dry state. 

In no single case was any pi^eliminary courtship wit- 
nessed in this species. There was no stridulation, no 
display of colour or attitude. It was entirely a question 
of capture, the females being almost invariably, at any 
rate at first, unwilling prisoners, although occasionally 
they showed indications of excitement in the presence of 
a male. 

It is highly probable that pairing takes place many 
times in this species, and even more than once with the 
same male. 

There was an extremely high proportion of individuals 
in coitu, even allowing for the fact that their habit of 
freely jumping about renders them much more con- 
spicuous than the unpaired males and females. The 
proportion was far higher than that of any other 
Orthopterous insect observed during this visit to Switzer- 
land ; it is possible, however, that the principal pairing 
time of other species is earlier in the year. 

GOMPHOCERUS SIBERICUS (var.). 

This form was excessively abundant round the W^eisshorn 
Hotel, no other species approaching it in numbers. On 
one occasion, after heavy rain, F. Jenkinsou saw immense 



242 Professor Edward B. Poulton on, the 

numbers of them lying in the path apparently 
dead ; but after the sun had warmed them they all re- 
covered. 

August 30. — At this date I had a good opportunity of 
watching the habits of the males in the presence of a 
female. About a mile from the hotel, along the upper 
road to Zinal, at about 11 a.m., I came upon a spot which, 
on account of its aspect and slope, had not long been 
warmed by the sun, so that the insects were only just 
beginning to bestir themselves. Here was a litde group of 
this species — two males and a female — probably close to 
the place in which they had passed the night. The female 
was resting quietly on a small piece of rock, slightly 
moving her abdomen, probably in relation to respiration. 
Later on she drew each antenna beneath the first leg of 
the same side, or perhaps drew the leg over the antenna. 
It is probable that this movement is intended to wipe off 
the dew. The males often did the same, and the female 
rubbed its eye, probably for the same purpose. This 
explanation is all the more probable because I did not 
see these movements at any time when the heat of the sun 
was sufficient to have dispersed the dew ; although tliu 
species was carefully observed on many occasions. One 
male, standing by the female, was stridulating when I came 
up; the other was behind motionless. These three insects 
vi^ere extremely shy, although this was by no means the 
case at other times when individuals of this species were 
watched in the heat of the day. Although I approached 
so that my shadow was behind me, and very gently, the 
male beside the female was alarmed at each slight rustle 
or movement, raising himself on his legs and erecting 
his antenna), apparently thoroughly on the alert. Then 
when I kept perfectly still he resumed his former position 
and depressed the antennas towards the female, both of 
whose antennas were also generally depressed. He did 
not continue to stridulate, but, after remaining almost 
motionless for some ten minutes, except for cleaning his 
antenna) now and then, tui'ned his back on the female and 
apparently began eating the heather. In a few seconds 
the other male stridulated once or twice : the effect on 
the first male was instantaneous ; he stridulated for a 
second or two and then walked back to the female, 
depressed one antennas towards her and patted her on the 
thorax with one of the first pair of legs. After all this 



Courtship of certain European Acridiidse. 243 

attention she made no apparent movement, and the other 
male did not make any farther advances. The active 
male then walked away and met another female, 
stridulated beside hei- until she also walked off. Another 
male close at hand stridulated, and the active one 
immediately replied, akhough in this case no female was 
near. 

These observations illustrate the habits of the species 
in courtship, the males, as Mr. F. V. Dickins also pointed 
out to me, always running after the females and never 
jumping, although both sexes jump very actively when 
disturbed. The use of stridulation as one of the tactics 
of courtship was clearly seen, the rivalry between the 
two males near the female being particularly interesting. 
The same occasion gave rise to the other method of 
courtship, viz., patting the female. The position of the 
male's antennas suggested attention to any movement the 
i'emale might make, or to anything she might do. 

These notes also illustrate the immense abundance of 
the species, the active male had only to walk two or three 
inches away from the group of three in order to come 
across another female and male. 

I think that, in observations of this kind, it will be 
useful to watch the species under many different conditions, 
especially as regards temperatuie. In the hottest places 
courtship is most energetic, and we have the most 
favourable opportunity for seeing the whole process 
carried through to completion, as in the case of 
Fezotettix already described ; but when the temperature 
is lower, and especially when the warmth of the sun has 
only just roused the insects into activity, many interest- 
ing details may be witnessed which are often passed over 
or hurried through in times of greater energy. 

In spite of the excessive abundance cf the species and 
the almost constant attention of the males to the females, 
a successful termination to courtship was witnessed in no 
single instance, and only two or three pairs were seen in 
coitu. One of these was found on August 29th, a little 
below rhe hotel. The male, unlike the Fezotettix, was 
unable to retain his hold, and when the female jumped, 
as she did freely, he was dragged along on his back, and 
retained this position for a considerable time in the 
intervals between two successive jumps. It is probable 
that with this species, the pairing season was nearly over j; 



244 Professor Edward B. roulton on the 

and this conclusion is supported by the fact that the 
females were often seen engaged in oviposition. 

August 81. — Jenkinson and I watched several females 
ovipositing in the loose earth on a very hot slope just 
outside the hotel, and in the beds of the little Alpine 
garden. The female thrusts her abdomen deeply into the 
earth and remains in this position for some minutes. Oti 
two occasions a female, after withdrawing her abdomen, 
was seen to rake the ground vigorously with her third 
legs, and, in one case, witnessed by Jenkinson, she 
steadied herself by holding a plant stem with her 
mandibles. We several times dug up the earth and 
searched for the eggs, but without success. At this date 
I found another pair of this species in coitu, on the path 
just below the lioteL 

GomjiJtoccnis sibericus appears to be a very general 
feeder, and its extraordinary abundance in the immediate 
proximity of the hotel was probably due to the presence 
of horses' and mules' dung, and other refuse upon which 
they fed. Every patch of dung upon the path was 
surrounded by dozens of individuals. 

August 31. — F. Jenkinson and I watched the males pur- 
suing the females near the hotel. It often happened that 
when a male came up to a female he extended the max- 
illary and labial palpi towards her, and raised himself on 
his legs in a very characteristic and remarkable attitude. 
At other times these movements occurred at a later stage 
of courtship. The movement of the palpi strongly sug- 
gested their use as organs of sense. When the female 
ran away, as she generally did, the male pursued, always 
trying to get in front of the female and thus stop her. 
The rr.ale ran faster than the female, and altered his 
direction so as to approach the female almost at right 
angles to the course she was pursuing. After the pre- 
liminaries of courtship — pursuit, stridulation, attitude, 
and movement of the palpi — the male, standing beside 
and close to the female, tries to jump on her, making a 
curious short chirp as he does so. The attempts were, 
however, always unsuccessful in the cases observed by us. 
Stridulation is in this species of definite length, and ends 
in two or three short chirps; in most cases the male then 
instantly approaches still nearer and tries to jump on the 
female with the short chirp already described. 

Neither Jenkinson nor I can remember the exact 



Courtslii]) of certain Euroi^ean Acridiidw. 245 

order in which the male went through the various phases 
of courtship. It is probable that the order varied greatly, 
and that some of the phases were often omitted. 

September 2. — On this and many other occasions the 
males were often seen to leave the female they were 
pursuing and, apparently without knowing it, to follow 
some other female they accidentally came upon in the 
course of the pui'suit. A male pursuing a female was 
once seen to approach and jump at the male of Pezo- 
tettix, having apparently mistaken it for the female. 

September o. — On the grassy slopes below the Bella 
Tola, a male observed by F. Jenkinson and me was 
greatly excited by the pair of Pezotettix already described 
as attempting, but unable to copulate. He stood in the 
characteristic attitude, walked round them, and finally 
stood in front and stridulated for the usual length of 
time and with the usual ending, he then advanced as if 
to jump, but before doing so became satisfied that he had 
made a mistake, and walked awa}'. It was evident that 
he had mistaken the pair for the female of his own species. 
Just below the zigzags up the Bella Tola we saw a 
male which, standing by a female, repeated the stridula- 
tion four times with the usual conclusion on each occasion, 
and then after all this attention let her walk away unper- 
ceived. This and the other facts already described seem 
to show that the males were very unobservant. In this 
respect their behaviour was very different fVora that of 
Pezotettix, and from the very alert member of their own 
species observed on August 30. 

No light was thrown upon the function of the remark- 
able dilated tibite of the first legs of the male. The 
whole tibia, swollen into the shape of a pear, with the 
tarsus articulated to its broader end, presented a most 
curious appearance in the characteristic attitudes assumed 
during courtship. On the underside of this dilated mass, 
which is approximately circular in transverse section, two 
rows of hairs are seen. Although the hairs are smaller, 
and the rows more widely separated, both evidently cor- 
respond to those which are found beneath the unmodified 
tibiiB of the other legs. 

Although we observed the habits of this species on 
many other occasions, neither F. Jenkinson nor I had 
ever seen the pairing accomplished. I therefore asked 
Mr. F. V. Dickins if he would consent to watch throug^h 



246 Professor Edward B. Poulton on the 

a very hot afternoon. This he very kindly did, and 
although unsuccessful in this respect, he made many 
interesting observations which I give in his own words : — 

''On the 4th September, 1895, I watched the courting 
habits of some grasshoppers on the knoll immediately 
behind the Weisshorn Hotel. 

" At first I made my observations on the west slope, 
but there was a cool wind blowing, and the insects were 
neither numerous nor lively. Casting about I discovered 
on the south-east slope a particular hollow away from 
the wind, in the full glare of the sun, and focussing the 
heat-reflections from the hillock-slopes around it. Hei-e 
the grasshoppers abounded and were very lively ; I 
watched them for about two hours. 

" I noticed that the males, marked by swellings on 
their first legs, were much more mobile than the females, 
the latter were mostly extremely passive and had to be 
chased and caught up by the males. There was a good 
deal of this chasing which was very amusing to watch. 
Sometimes the female, as if bothered, would remain 
quiet for a time and allow the male to come up to her. 
He appeared to stroke her with his antennge, but I could 
not distinctly see what parts of her body he thus specially 
caressed. The insects never seemed to leap unless 
alarmed ; I thought that perhaps leaping was not an 
ordinary mode of progression. I saw no male clasp or 
leap upon any female ; they chased and chased, threw up 
the game, started a fresh pursuit, equally bootless, and 
so went on, tireless. I was not fortunate enough to see 
any accouplement. When the male was alongside the 
female, in many cases, the insect assumed a strained atti- 
tude, the anterior part of the body being raised high, and 
the terminal segments curved upwards so that the dorsal 
line was concave antero-posteriorly. Very often a curious 
little click was heard, I thought, usually as the chase 
ended in the pair suddenly standing still by each other. 
One might suppose that it was a chirp of triumph. I 
have no doubt it was made by the male. 

" One rather curious situation in this active little 
drama is worth noting. A female alighted or rather ran 
up on ray boot and sat quite still in the hot rays of 
the sun. She sat so still that the idea struck me I might 
try to caress her a little myself. I accordingly looked 
round for a slender flexible grass stem or dried haulm. 



Courtship of certain Etirojoean Acridiida'. 247 

and having found one gently touched her with the pliant 
extremity. She did not stir, and I became bolder ; I 
rubbed her lydy on either side and also the inside of the 
coxa3 and antennas. She was still unmoved, except that 
a slight rigidity seemed to supervene^ and the abdominal 
extremity curved slightly upwards. Gently tickling this 
part the curve rose and the rigidity seemed more marked. 
1 now stroked her as gently as I could, and she permitted 
this extreme familiarity Avithout resentment. Lastly, I 
took her softly up and laid her in the palm of my hand. 
Turning her from side to side she seemed quite content 
and did not exhibit a flutter or a tremor. I continued 
my caressings for ten minutes or a quarter of an hour, 
and then laid her in a warm spot and watched her for 
another quarter of an hour. She did not move, although 
she was alive enough. Was she hypnotized ? " 

This last interesting observation suggests that very 
marked effects may be produced by the patting which I 
witnessed on August 30th, and by the nibbling in the 
case of PezoteMicO. In this latter species, indeed, the 
effect produced on a female after her first unsuccessful 
attempts to throw off the male, appeai'ed to be very 
much like that induced by Mr. Dickins in the female of 
Gompliocerus. 

STETHOrUYMA FUSCUM. 

This magnificent species was very abundant in the 
open grassy spaces between the trees at the water- 
courses some few hiindred feet below the hotel, and also 
in certain places on the slopes far below the Bella Tola. 
The stridulatiou was far more characteristic than that of 
any other species observed : first three (sometimes two) 
sti'okes of the third legs across the tegmina, then a rapid 
vibration of the former against the latter for a few 
seconds. The result is three piercing sounds in rapid 
succession, and then a prolonged rustle. The rivalry 
between the males and their replies one to another were 
very evident, but their relations to the female were only 
witnessed once or twice. 

August 31. — This species was observed by the water- 
courses. Many females were seen but never attended 
by males on this occasion. I came across a pair of males 
in the grass fighting in a very clumsy manner : they lay 



248 Professor Edward B. Poulton on the 

side by side, pushing and kicking at each other, and 
stridulating alternately. One male had lost one of the 
third pair of legs, perhaps in an earlier part of the 
fight, but if so it must have been somewhere else, as I 
searched for the leg in vain. In spite of its mutilation 
it replied with its single leg to every stridulation made 
by the other, and these replies seemed especially irri- 
tating to the uninjured male for it kicked more vigor- 
ously than ever, and once made a determined but unsuc- 
cessful effort to bite the end of the other's abdomen. The 
fight was already raging when I began to observe. After 
I had watched it for several minutes the uninjured male 
gave up and went away. It is possible that the light 
may have begun by one male leaping on the other in 
mistake for a female, but it is more lilcely that it arose 
in a quarrel over one female. This view derives some 
suppoi't from the following observation. 

September 2. — At a certain spot on the slopes below 
the Bella Tola the species was very common, and several 
pairs were seen in coitu. The female is larger and 
duller in colour than the males, and her wings are much 
smaller and probably useless for flight. 

In the case of one pair in which copulation had 
evidently only just taken place, the female was seen to 
expel fteces : another male was lying beside the pair 
evidently trying to copulate with the female, continually 
stretching his abdomen towards her with partial eversion 
of the organs. He also stridulated from time to time, 
and I feel almost sure, although I cannot speak with 
certainty on this point, that the copulating male replied 
on each occasion. In a few minutes the unsuccessful 
male went away. I have suggested that the fight may 
have begun in souie such contest, but probably before 
either male had succeeded in pairing. I cannot now 
remember whether the stridulation during the fight and 
on the occasion last described was similar to that v/hich is 
characteristic of the species at other times. I am con- 
fident that no new sound was introduced, but cannot be 
sure as to whether both movements were made with 
their usual relation to each other. 

September 7. — F. Jenkinson saw two males of this 
species drawn together from a distance of several yards 
apparently as the result of stridulating alternately. 
When at length they met, they seemed much excited. 



Courtship of certain European Acridiidse. 249 

but soon separated without fighting. Perhaps the fight 
which I witnessed may have begun in this way. 

StENOBOTHKUS (?) ELEGANS. 

A beautiful little species which Dr. Sharp doubtfully 
identifies as Stenohothrns elegaiis, was often seen, although 
not abundant, below the hotel. The males in stridu- 
lating, do not, like the two last mentioned species, move 
the third' legs symmetrically, but one follows the other. 
Probably in consequence of this the sound swells and 
diminishes rhythmically, presenting a remarkable likeness 
to that made by a fly caught in a spider^s web. Con- 
sidering its very small volume, this high and piercing 
sound can be heard for a great distance. 

StENOBOTHRUS H.EMORRHOIDALIS. 

After 1 left, F. Jenkinson observed a very small kind 
which is almost certainly to be identified as the above 
named species. Mr. Jenkinson has kindly given me the 
following notes : — 

*' September 5. — About 5 p.m. I found a very small 
brown male, with the dorsal surface of the abdomen of a 
reddish-orange colour. He was very assiduous in his 
attentions to a green female with white V-shaped marks 
on the side of the thorax. He generally kept close to 
her, but was never obtrusive in his attentions, relying 
apparently on the effect of his stridulation. This was 
made with both legs simultaneously, generally very low, 
but sometimes louder, a rapid uniform trill, rather like 
the note of the lesser whitethroat. Sometimes she gave 
him the slip, and they were as much as eight inches 
apart, and out of sight of each other ; but he continued 
at 'short intervals his stridulation, and somehow, 
apparentlij by accident, they came across each other 
again, and the male posted himself in close attendance 
as before. The female was generally nibbling at blades 
of grass. If the male touched her, she seemed to repel 
him by raising one of the third pair of legs. At 6*45 
the sun was setting, and I had to go, so I boxed them 
both. The male was perhaps just beginning to relax his 
energy. 

"September 7. — Below Weisshorn Hotel. A male

successful in finding her again than any other species I 
have observed. At 5*30 the male jumped on the 
posterior part of the female's body, his legs round her 
tegmina. In this position he continued to stridulate 
although at rare intervals (he did so at 5"50). The 
female carrying the male shifted backwards moving her 
abdomen. She seemed to have some difficulty in expelling 
ffEceSj and this was apparently the cause of the movement. 
The male stridulated, and then at G'O, without having 
copulated^ he quitted the female, stridulated, and went 
away." 

PSOPHUS STRIDULUS. 

The large black males were common just below the 
hotel, and on some slopes below the Bella Tola, where 
Stethophyma fuscum ahounded. Their red under wings 
were very conspicuous when flying, the characteristic 
rattling sound still further attracting attention to them. 
The larger brown, toad-like females, with smaller wings, 
are probably unable to fly. 

I never saw the sexes together ; but after I had left, 
F. Jenkinson kindly sent me the following notes : — 

" September 5. — When the male finds himself near a 
female, he utters a double ' twitter ' (once a twitter and 
then a trill), and moves excitedly. In one case I saw 
him leap on the back of a female, but presently he left 
her of his own accord. 

" At 3 p.m. I came across a pair in coitu, but the male 
disengaged himself by vigorous movements of the third 
legs. They remained for a long time within two inches 
of each other, but nothing happened. I made the female 
jump away, caught her, and put her in the male's way. 
He at once became excited, and twittered, but the female 
escaped. This occurred more than once, when I lost 
her. 

" A male, disturbed as I came home (about 6'45 p.m., 
when the sun was setting), hopped vigorously, but did 
not open his wings." This latter observation is of inte- 
rest, because the males always took to flight, when dis- 
turbed,, on other occasions. 

" September 7. — On placing the female near the male, 
he became excited, and made a twittering sound with 
his legs. The female, in moving oS", showed the red 



Courtship) of certain European Acridiidce. 251 

under wingSj but even in the open path, the male seemed 
to lose her at once. In another case, when the female 
came near, the male jumped right away/^ 

It is noteworthy that most of the observations upon 
the last-named two species were made late in the afier- 
noon, when the sun was losing its power. 

CEdipoda ccerulescens. 

I had long wished to study the courtship of these 
beautiful insects, but there were none round the Weiss- 
horn Hotel. Lower, at San Luc (5390 feet), they began 
to appear, and still lower, at Vissoye (4006 feet), and all 
along the main valley road, they were excessively abun- 
dant. They are always difficult to observe, because they 
haunt places where the combination of direct heat with 
that reflected from rocks or bare slopes, is almost un- 
bearable. I had no time to observe them until we had 
come down to Fribourg. 

September 9. — These insects were very abundant in a 
large gravel pit, just outside the gate of the town, on the 
road to La Roche. There is little doubt that they be- 
longed to the above-named species. They were very lively, 
continually flitting about over the bare earth and gravel. 
They are very shy, and it is necessary to keep perfectly 
still in the intolerable heat, in order to watch their habits. 
I noticed that the males move their third legs as if in 
stridulation, but that no audible sound was emitted. 
There is an apparent lack of intention and eflbrt about 
their movement which suggested that the habit is pro- 
bably only a vestige, and possesses no other significance. 
The legs were raised, and seemed to be allowed to drop 
by their own weight. Furthermore, these strokes were 
not repeated at regular intervals, but quite irregularly, 
and often singly. In this case I did not secure any 
material, and therefore cannot speak with any confidence ; 
but I anticipate that the legs will be found to be without 
the sound-producing structures. 

A female remained motionless on the ground near to 
me. She was much larger than the males, and the ex- 
posed surface of her body and wings was of a redder 
brown. The males were extremely acute in detecting 
her presence, although she made no movement, and 
looked exactly like a part of the ground. Whenever a 



252 Prof. E. B. Poulton on European Acridiidx. 

male perceived her, he instantly approached without any 
preliminary courtship, leaped upon her back, i-emaiiied a 
few seconds, and then voluntarily left her. The female 
did not make any apparent movement, although I saw 
quite half-a-dozen males leap upon her in the course of 
a few minutes. The males never met near her, and I 
saw no signs of any fighting. I could not tell whether 
there was any actual pairing, but it is improbable that 
this could have occurred in so short a time. It is likely 
that the males found that she was in some way unfit for 
pairing, and then left her. I have already implied that 
there was no special display of the beautiful blue under 
wings for the benefit of the female. 

I trust that I may be able to make further observations 
upon these beautiful and interesting iusects at some later 
date.

joints provided with long hairs, as in this geous.

A single specimen of a species which seems to present 
all the essential characters of this genus. The wings 
have the first and third veins distinct, but lack the 
posterior forked cell. The legs are short and not slender. 
The tibiae are as long as the first two joints of the tarsi 
together, and the first joint is a half longer than the 
second.

A single specimen of a minute species shows evident 
relationship to this genus, though I am not fully satisfied 
that it should be located in it. 



Diptera of St. Vincent {West Indies). 255 

The neuration is very nearly the same as that of the type species 
(comp. Karsch, /. c, fig. 1). The first joint of the tarsi is about 
one-third of the length of the second joint, which is as' long as all 
the other joints together. The fifth joint is widened, somewhat 
disk-like,andisaslongas the preceding joint. The head is wanting. 
The colour of the remainder of the insect is light yellow, with the 
mesonotum brown. Length about | mm. 

Trichopteromyia, n. g. 
Allied to D'/nmyza (in Schiner's sense), but the first and third 
longitudinal veins are not crowded together anteriorly, the third 
vein terminating at the tip of the wing. Wings broad, very hairy ; 
proximal section of the third vein straight, the distal section 
nearly straight ; pref urea of forked cell scarcely longer than the 
sixth vein. Antennae with the joints distinctly petiolate ; the 
distal portion of the antennis in both specimens is wanting. 
Metatarsi longer than the following two joints together. 

The genus Diomyza is, as yet, not well known, and I 
do not feel quite sure of its distinctive characters. As 
Schiner defines it, it differs from Lasioptera only in the 
elongate metatarsi. However, there has been much 
confusion in the application of the name Diomyza, as 
Karsch has shown (Revision der Gallmucken, p. 13), 
and it may be that the name will have to be abandoned. 
The present genus seems to be the only other oue known 
with elongate metatarsi, in which the fifth vein is forked.

basal cross-vein ; a similarly coloured spot at the tip of the first 
vein, reaching across the third longitudinal vein ; the tip of the 
wing is broadly brownish, and there is a small brown spot in front 
of the fourth vein, opposite the tip of the auxiliary vein ; anterior

Six specimens. 1000-1500 feet. In some of the 
specimens the face is brown, the front wholly black, the 
posterior part of the pleuraa black, and the abdomen, for 
the greater part, of the same colour. The species must 
be nearly related to N. ventralis, Say, but the infuscated 
wings and the absence of a distinct terminal fascia, seem 
ample to distinguish thetn.

Four specimens. 

ManotAj n. g. 

Head flattened, placed rather high as regards the thorax ; face 
and front broad, the autennje situated high up, directed upwards 
and forwards ; composed of sixteen joints closely united, the basal 
joints a little differentiated from those of the flagellum. Three 
ocelli of nearly equal size, situated near the vertex, in a gently 
curved line, the lateral ones about as far from the inner borders of 
the eyes as from the middle one. Palpi composed of three joints, 
elongate, the terminal joint slender and directed angularly back- 
wards. Dorsum of thorax moderately convex ; scutelhim with short 
bristles. Abdomen slender, flattened cylindrical. Femora stout, 
flattened ; front and middle tibiae with one, the hind tibite with 
two spurs ; hind tibiae and metatarsi with a row of short bristles 
on the outer side ; all the tibite without long bristles ; coxaj elongate. 
Wings longer than the abdomen ; auxiliary vein rudimentary ; the 
first vein terminates before the middle of the wing ; third vein 
not furcate ; fourth vein wanting, save the distal portion of its 
branches ; fifth vein furcate near the basal portion of the wing ; 
the costa extends a considerable distance beyond the termination 
of the third vein. 

As in the following genus, the proximal portion of the 
tvi^o outer veins is so w^holly obliterated that it is impos- 
sible to trace them. 

1. Manota defecta, n. sp. (PI. VIII., fig. 14.)

middle of the abdomen if bent backward. Face and front 
brownish-yellow. Mesonotum reddish or yellowish- brown, finely 
white pubescent. Pleurae a little lighter coloured. Coxae and 
femora light yellow, the middle coxae near the upper part with a

Length 2-2^ mm. 
Six speciaiens. 

Probol.?:cs, n. g. 

Proboscis more than half of the length of the body, slender, 
directed downwards and forwards, composed of five slender 
bristles ; palpi wanting. Antennae sixteen-jointed, compressed, 
the joints closely set together ; first two joints only a little 
differentiated from the others. Head composed almost wholly of 
the eyes ; face very narrow ; front narrow below ; eyes pubescent. 
Thorax strongly convex, nearly bare, a few short bristles on the 
sides. Scutellum small, with about six small bristles. Abdomen 
slender, elongate, longer than the wings ; male organs composed of 
a pair of simple, fleshy forceps. Four anterior legs very slender ; 
hind legs stouter and much elongate, the femora thickened, and 
the tibiae clubbed. Xeuration defective ; third vein entirely 
separated from the first, and without anterior branch ; proximal 
portion of the fourth and fifth veins wholly invisible ; sixth vein 
complete. The costa reaches a considerable distance beyond the 
tip of the third vein. 

This genus is remarkable in the apparently entire 
absence of the palpi. The closest examination of our 
three specimens has failed to reveal any trace of them. 
The labium, or sheath for the other mouth-parts, is 
quite rudimentary. In the wings there is not the 
faintest trace of the proximal portions of the fourth and 
fifth veins ; those portions that are present are by no 
means weak. An equally minute examination fails to 
show the ocelli, though I will not be positive that they 
are not present. The presence of tibial spurs, the 
moderately elongate coxeb, and the generiil relationship 
to other species of the family, especially Gnoriste, seem 
to prove the correct location of the genus here.

branch of the fourth vein, to connect with a spot running from 
the first posterior cell into the hindmost posterior cell ; a smaller

Front yellow or yellowish-red ; in width a little less than one- 
third of the head ; facets of the eyes uniform in size. Antennas 
brown or blackish, finely pubescent, composed of thirteen joints, 
of which the first two are swollen, and the third somewhat dilated. 
Palpi small, for the most part concealed. Proboscis nearly four 
times as long as the vertical diameter of the head. Eyes pube- 
scent. Thorax yellow or yellowish-red, the mesonotum a little 
darker in front, the pleurae with patches of silvery lustre. 
Abdomen dark brown, the basal segments more or less yellowish. 
Legs yellow, the femora with blackish bands on the distal half, 
the tarsi blackish towards the tip ; hind tibiie with spurs. Wings 
pure hyaline. 

Four specimens. The present species, thougli seem- 
hig to agree closely in its structural characters with 
P. sxiperhiens, Schiner, differs, aside from the markedly 
smaller size^ in the absence of black spots on the 
mesonotum. It is not at all improbable that our 
specimens are conspecific with those mentioned by 
()sten Sacken (Cat. Dipt., 197d, 17,218) as occurring in 
Mexico. 

Sacl-eniella, n. n. — Since the appearance of my paper 
(Kansas Univ. Quart., i., p. 110) in which I described a 
new genus of this family, I have discovered that the 
name Snoiuia, there used, has been previously employed 
for a genus of Lepidoptera. I here therefore substitute 
Sacl-eniella in honour of Dr. C. R. Osten Sacken.

Elephantomyia. 

Osten Sacken, Proc. Acad. Nat. Sci. Phil., 1859. 
1. Elephantomxjia longirostris, n. sp. 

$ . Proboscis about one and a-half times the length of the 
body ; wings with a brown stigma and brownish clouds along the 
cross-veins. Length of body 6 mm, of proboscis 8^ mm. 

Head yellow. Proboscis very distinctly longer than the bodyy 
finely pubescent. Antennre brownish-yellow ; basal joints yellow,

This species is evidently closely allied to the type of 
the genus, and I at first believed that it was the bame-, 
but the more elongate proboscis and the brownish clouds 
of the wings seem sufticient to separate them.

brownish-yellow, the male organs more yellowish. Legs brownish 
throughout, the tarsi finely pubescent. Wings nearly hyaline ; no 
stigma. Length 3-4 mm. 

Twelve specimens. This and the following species 
differ from the type of this o^euus, as described by Osten 
Sacken, in the stracture of the antennse and in some 
peculiarities of the neuration, but the differences will not 
justify generic separation. Both species have distinct 
empodia, and there appears to be a minute spur on the 
middle tibias. 

2. Atarha jyleuralis, n. sp. (PI. X., figs. 61, antenna; 
61a, h, genitalia ; 61 c, wing.) 
cJ , $ . Front yellow. Antennge and palpi blackish. Meso- 
notum brownish-red ; the colour in shape of an elongated triangle, 
the base of which is the scutellum ; the lateral margins of the 
mesonotum show a slender, dark-brown stripe ; immediately below 
which the colour is light yellow, extending over the dorso-pleural 
suture. Pleura3 dark-brown, with a longitudinal stripe above the 
base of the coxse ; or, the pleurje may be otherwise described as 
having two dark brown stripes enclosing a light yellow one. 
Abdomen brownish-red, with a narrow, dark-brown band on the 
posterior margin of each segment, and with a median, indistinct 
brownish stripe. Coxffi light yellow; femora yellow, with a 
brown ring just before the light yellow tip, whichi colour ex- 
tends narrowly on the base of the tibiae ; tibi« and tarsi brown. 
Wings tinged with brown ; stigma dark-brown ; the marginal cell 
is shorter and wider than in A. pudla. Length 4-5 mm.

Sixteen specimens. The description of this species 
applies so well to these specimens that there can be but 
little doubt of the identification. The brown stripes of the 
mesonotum are only feebly indicated in most of the speci- 
mens ; the posterior part of the abdominal segments is 
yellow, and the tibiae are brownish.

the antcnnfe yellow ; flagellum brown or black. Mesonotum 
shining, with three broad, more or less confluent, shining, deep 
broad stripes, the middle one not reaching the suture, the lateral 
ones not extending far in front of it ; elsewhere the mesoKotum, 
like the scutellum and anterior part of the metanotum, is light 
yellow. Pleurte dark yellow or brown ; when seen obliquely, with 
a silvery sheen. Posterior part of metanotum brown. Abdomen 
yellow, with a broad brown band on the anterior part of each 
segment. Legs yellow ; all the femora brown at the tip, and with 
a brownish ring beyond the middle ; all the tibia3 and the first 
three tarsal joints brown at the tip, the last two joints of the tarsi 
black. Wings hj'aline ; the stijma and a cloud at the end of the 
costa — sometimes obsolete — brown. Length 7-8 mm. 

Twelve specimens. In one female the abdomen is black, 
with a narrow yellow posterior margin to the segments ; 
ill others brown, with a broader yellow border. The 
neuration is very much like that of T. com'plexa ; both the 
second and third veins are cui'ved less, and the second 
vein extends further towards the tin of the wino-.

ish in places. Abdomen light luteous yellow. Legs yellow ; the 
tip of femora, tibiae, and the distal joints of the tarsi brownish. 
Wings hyaline ; stigma faintly brown. Length 5 mm. 

One specimen. The present species can hardly be a 
true Ulliptera, because the anterior veins do not show 
the approximation characteristic of that genus, but it 
seems to agree in all other respects. The antennae are 
sixteen-jointed, the joints oval in shape ; the thorax is 
gently convex, the pronotum small, the abdomen is 
elongate, etc. The neuration is shown in the figure. 
There are uo spurs to the tibia3.

both thickened ; the following joints slender, distinctly separated, 
finely pubescent. Rostrum rounded, a little prolonged, but 
shorter than the head ; polpi inserted towards its base, rather 
slender, the ultimate joint shorter than the penultimate, the two 
together about equal to the antepenultimate joint. Front rather 
narrow ; vertex but little developed. Legs very long and slender, 
finely pubescent ; tibiaj without spurs ; ungues simple ; no 
empodia. Male forceps not large, in the dry specimen showing 
two obtuse, fleshy lobes. Valves o£ the ovipositor small, slender, 
arcuated. Auxiliary vein nearly as long as the first longitudinal 
vein, joining the costa in an acute angle ; the subcostal cross-vein 
at some distance before the tip. The second longitudinal vein 
arises at some distance before the middle of the wing, with a 
strong curve backward ; nearly opposite the distal end of the 
discal cell, it gives off an oblique branch to the costa ; marginal 
cross-vein long and oblique, sometimes joining the proximal end 
of the anterior branch. The beginning of the third vein in the 
same straight line with the first section of the second vein, 
terminating in the fourth vein at the proximal end of the discal 
cell. Anterior cross-vein wanting. Anal cell narrowed in the 
margin. Seventh vein very short. 

This singular ^enus is remarkable, if my interpreta- 
tion of the neuration is correct, in the entire absence of 
the first posterior cell, the second submarginal cell 
lying in contact with the discal cell and the second 
posterior cell, through the absence of the small cross- 
vein and the greater part of the third vein. It is difficult 
to see how there can be any other interpretation, as the 
branch of the second vein that takes the place of the 
small cros?-vein cannot possibly be that cross-vein, for, 
in that case, it would arise from the second vein — an 
impossibility. Furthermore, this interpretation seems 
probable from a study of the neuration in ParatwjJesa, 
where the first posterior cell begins at the outer end of 
the discal cell. The relationship seems to be with that 
genus, but I cannot agree with Osten Sacken in con- 
sidering the anterior branch of the second vein an 
adventitious cross-vein. There are two submarginal cells 
present, as in Gonomyia. Aside from the fact that there 
are only three posterior cells present, which may or may 
not be a generic character, the shortness of the seventh 
longitudinal vein is sufficient for the separation of the 
genus.

The foregoing, without change, was written in the 
belief that our specimens represented a new genus. A 
more careful search of the literature, however, revealed 
to my surprise the congenerousness of the species, 
especially M. alhitarsis, DoL, included in the genus 
Mongoma. The species hitherto made known — seven or 
eight in all — are from Java, Sumatra, the Philippine 
Islands, Borneo, Madagascar, and Southern Africa. 
]ts occurrence in the western continent is of great 
interest. 



1, Mongoma manca, n. sp. 

^ , $ . Front and basal joints of the antennse brownish red ; 
flagelluni of antennae and the palpi brown or black. Thorax, light 
brownish-red, the metanotum sometimes a little darker, and the 
pleuriB more yellow. Halteres yellow. Abdomen brown or 
brownish-red, the terminal segments more reddish. Legs brownish; 
base of femora and the distal joints of the tarsi more yellowish. 
Wings nearly hyaline ; stigma small, rounded, brownish. Length 
7-8 mm. 

Six specimens. Forest, 2000 feet, July. 



2. Mongoma pallida, n. sp. (PL X., fig. 67, wing.) 

jj, $. Wholly light yellow, the front and outer joints, the 
antennae, only, brown or brownish; the legs a little darker. Wings 
pure hyaline, with light-coloured veins ; no stigma ; the distance 
between the junction of the marginal cross-vein and the origin of 
the anterior branch of the second vein greater than in M. manca, 
nearly as great as the length of the antei-ior branch itself. Length 
6 mm. 

Four specimens. 1000-1500 feet. In addition to 
the smaller size, much lighter colour, and more hyaline 
wings, the species will be readily' distinguished by the 
shorter outer submiarginal cell. In the present species, 
its inner end, in all the specimens, is opposite the inner 
end of the second posterior cell; in M. manca the 
proximal end is, in every case, at a considerable disiance 
proximad to that of the posterior cell.

subinfuscated. Length 12 mm. 

Antenna3 in the male black, the proximal three or four joints 
yellow, about as long as the front femora ; in the female, yellow, 
with the proximal end of the sixth and following joints black, and 
only about as long as the mesonotum. Thorax light yellow, the 
mesonotum brownish. Front, rostrum and palpi yellow, the last a 
little brownish at the tip. Halteres brown. Abdomen reddish- 
yellow, the lateral margins of all the segments, a part of the sixth 
segment, and all of the seventh, black (in the female specimen the 
abdomen is wanting). Legs yellow, the tip of the tibiae, and the 
tarsi for the greater part, black. Wings uniformly tiugeJ with 
brown, the costal cell and the stigma pale brown. 

I can find no description which will apply to this 
species, though that of T. inftiscata, Loew, will nearly 
do so. The colour of the antennae in the female will at 
once distinguish the two.

the middle blackish. Abdomen dark brown. Legs luteous, the 
base of the femora yellow ; tarsi white, except the metatarsi of the 
two anterior pairs, the proximal end of the second joint of the 
same pairs, and of the metatarsi of the hind pair, which are 
brown. Wings distinctly tinged with brownish. Length 6-7 mm. 

Four specimens. Hitherto, only South American 
species of this genus have been made known, from which 
the present species seems distinct. The male antennae 



Diptera of St. Vincent [IVetit Indies). 297 

were originally described as having twenty-eight joints, 
and the true number, sixteen, was not known till speci- 
mens were examined by Loew. The joints in this sex 
are very closely united, and it is only by close exami- 
nation that the number can be made out. From 
P. fiisca, Wiedemann, and P. ohscura, Macquart, which 
seems to be a distinct species, the present appears to be 
so closely allied, that the short descriptions will hardly 
distinguish them. However, Wiedemann figures the 
female antennte as elongate, like those of the males, but 
■with simple, not constricted joints. In the present 
species, the female antennas are short, in fact not longer 
than the thorax, and are of the ordinary Tipulid struc- 
ture ; that is, the joints are oval, slightly hairy, and are 
easily distinguishable. The first joint is not cylindrical, 
and is not provided with short, closely-set hairs, as is 
described. The figure given by Macquart shows short 
and abundant hairs on the swellings of the male 
antennas, very different from the long, delicate hairs of 
the present species. 



Specjes Ikcert^ Sedis. 

Two species of Tipulidw, represented by single, more 
or less mutilated specimens, I cannot locate. I give 
figures herewith, which will, I believe, render the identi- 
fication not doubtful. One of them (PI. X., 6gs. 72 and 
72a) possibly represents a new genus. The tip of the 
antennas is broken ofi", otherwise the specimen is com- 
plete. If the antennae are but 14-jointed, the species 
would be located in RJiipidia, from which, however, the 
structure of the male organs show distinct differences, 
and the antennae are hardly sufficiently pectinated. If 
there are sixteen joints, Schiner^s and Osten Sacken's 
tables will carry the species to Antocha. This genus and 
Thanmaslopteva are almost the only ones in this group 
which I do not know. Still, the neuration is sufficientlv 
distinct to render its location with ^?i^ocAa practically out 
of the question.

$. Head black, lightly greyish-pruinose ; palpi aud rostrum a 
little reddish. Antenna3 black, the basal joints somewhat reddish. 
Thorax yellow, the mesonotum with three dark-brown stripes, the 
median one abbreviated posteriorly, and divided by a slender line ; 
the lateral ones begin a little before the termination of the median 
one. Scutellum and mesonotum brownish-yellow. Abdomen dark- 
brown. Legs brown oi- yellowish brown : the tip of the hind 
tibiae and their tarsi blackish ; the femora, for the greater part, 
yellowish ; hind tibite thickened at the tip. Length of body 2 mm., 
of wings 3 mm. 

Four s])ecimens. This species must be closely allied 
to D. clavata, Loew, from Massachusetts, and I was, at 
first, inclined to identify it with it. It differs from the 
description, however, in several important points. The 
pleur«3 are immaculate yellowish, the legs are darker 
coloured, and the wings are uniformly tinged with 
brownish, not hyaline, with markings.

at an angle with the third joint ; its first joint small ; second joint 
thickened, spindle-shaped, finely and densely hairy, terminating in 
a slender bristle about as long as the thickened portion of the 
style ; altogether, the style is shorter than the third antennal 
joint. Thorax shining metallic, deep green, with blue reflections 
and erect black pile. Abdomen elongated, of equal width, black 
or brownish black, the second, third, and fourth segments with a 
narrow posterior margin of golden or silvery pubescence, forming 
an interrupted band. Femora black ; tibias light yellow with a 
broad brown ring beyond the middle ; the hind pair with the 
distal two-thirds brown ; tarsi light yellow or yellowish-white, the 
distal three joints of the four anterior ones, the tip of the meta- 
tarsi, and the remaining joints brown or brownish. Wings hyaline 
on the basal anterior portion ; clouded behind, and blackish on the 
outer half. Length 9 mm. 

Two males and one female. The female differs in being 
of a larger size (12 mm.) in the absence of metallic 
coloration, in tbe more reddish-brown colour of the 
abdomen, and in the lighter coloured wings. It may be 
an immature specimen. I at first identified this genus 
as Chromatopoda , Brauer, but it will be at once distin- 
guished by the structure of the second antennal joint.

one small and short, the sixth elongate and with several minute 
bristles at the tip. Scutellum with two slender spines. Abdomen 
slender, composed of five segments. Veins of the wings on the

pubescent. Pile of mesonotum and scutellum dusky, that on the 
spines white ; the spines are wholly of the colour of the mesonotum, 
and are shorter than in the male. Abdomen, as usual, with six spots. 
Length 7 mm. 

Two specimens. 1500 feet. The species is allied to C.

varies much. There are no structural differences in any 
of the specimens, and, in some of the San Dominican 
specimens, the colour of the bristles of the hind femora 
varies. Taking the above facts into consideration, I 
believe that all the names above given, and probably 
others, represent a single species of wide distribution. 
0. tibialis occurs through all of the Eastern United 
States, as far as the Rocky Mountains.

There are, in the collection, some twelve or more 
specimens, which I refer very doubtfully to this species. 
In the most typical, the chief differences from the 
description are : The presence of black hairs on the 
thorax, the darker colour of the front femora, and the 
light-brown colour of the basal portion of the wings. 
The distal portion of the wings is not hyaline, or even 
cinereo-hyaline, but is distinctly infuscated. In some 
of the specimens the wings are nearly uniform in colour 
throughout.

DOLICHOPODIDJE.* 

Of tliis family, the collection contains forty-six species, 
of wLich five only can be recognized as previously 
described. The study of so much material throws an 
interesting light on the geographical distribution of the 
genera. The entire absence of Dulichopus, of which the 
continent of North America contains nearly a hundred 
species, strongly emphasizes the fact that the genus is 
limited to the temperate and colder regions. On the other 
hand, more than half of the species in the present col- 
lection belong to the group which may be termed the 
C/trysotinw, embracing CJirysotus, Diapkorus, and several 
smaller genera, while this group is represented on the 
continent by a considerably smaller proportion. 

The discovery of a second species of the peculiar genus 
Polymedon, having identically the same habits as the 
Californian species, is a matter of great interest. 

In the desci-iption of new species, the aim has been to 
give a careful i-eview of the generic as well as specific 
characters in those not infrequent cases where there was 
possibility of an erroneous generic determination. I'he 
genera of DoUrJiojwdidfe are, at least in part, in need of 
thorough revision, and several new ones must yet be 
erected for North American forms. Unwilling to under- 
take what should be the work of a more experienced 
hand, I have avoided, as far as possible, the establish- 
ment of new genera in the present article. 

I am under the greatest obligation to Professor 
Williston, not only for the privilege of undertaking this 
work, but for the use of books and other valuable 
assistance.

vexities separated by a narrow groove ; colour dark brownish- 
green, with dense brown pollen, which appears lighter in certain 
directions. Palpi brown, with yellow tips ; proboscis large, 
blackish. Front concave, shining violet in the middle, about the 
edges blackish. Antennte brownish-black, the under part a little 
reddish ; third joint ovate, a little pointed in an upward direction ; 
arista nearly basal, short, distinctly feathered. Cilia of the inferior 
orbit white. Thorax bronze-green, not very shining ; acrostichal 
bristles in two rows ; the two rows of interior dorsal bristles (Mik) 
are inserted upon slender longitudinal shining blue lines, expanded 
posteriorly. The posterior margin of the dorsum is in the form of a 
thin projection, running around from the root of one wing to that 
of the other ; above this the surface is considerably dusted.

Cilia of tegula black. Tegulaj and halteres deep yellow. Abdomen 
olivaceous, sligiitly shining, on the sides shining green, and vent- 
rally white poUinose. Hypopygium free and rather large, but 
sessile ; colour black, a little dusted on the sides, the lamellse are 
brown, yellowish at base, rather long and narrow, with rounded 
corners and a fringe of long black bristles all the way around 
except basally. All the coxae brown, their tips yellow ; femora 
yellow, tibise brownish-yellow, the hind knees brown. Tips of 
front tibife lighb yellow ; first joint of fore tarsus of the same 
colour for two-thirds of its length, the remainder of the tarsus 
brownish-black. The joints beyond the first are short, and all are 
somewhat thickened ; the last is rather long, and bears a little 
prominence on the underside near the base ; the claw on the inner 
side is greatly enlarged, and bends back across this prominence as 
a straight spine, forming a grasping organ ; beyond this its point 
curves laterally, the other claw and the pulvilli are nearly normal, 
but the latter are inserted a little toward the side instead of 
exactly at the end ; the other tarsi normal, brownish-black beyond 
the first joint, which is short in the hind foot. Middle and hind 
tibiiB a little infuscated at the tip. Wings a little brownish, more 
so along the veins, costa a little thickened in its first part ; the 
fourth vein makes a gradual curve forward throughout its last 
section, the convexity behind (see figure). 

5 . Face wider and more prominent, the two convexities uniting 
below. Pollen more greyish. Palpi larger. Antennae more 
yellowish below. Front tibiae yellow with brownish tip, their tarsi 
simple, coloured like the others. Costa very much thickened before

green, sometimes coppery, more so along the front margin. Small 
humeral bristles (Mik) numerous. Viewed from above, there is a 
silvery pollinose spot behind the humerus, and another behind the 
root of the wing. Scutellum coppery. Pleurae mixed light and 
dark green, white-dusted. Tegulse yellow, their cilia black. 
Abdomen coppery, ou the sides more green, and veutrally some- 
what white-dusted. Hypopj'gium large and long, yet scarcely 
pedunculated ; the lamellfe proper are very small, yellow ; the 
outer basal portion of each gives rise to a stout claw, twice as long 
as the lamella itself, black except a little at base, and curving 
upward toward the venter. A row of black bristles runs along the 
outer side of the claw two-thirds of the distance to the tip. CoxaB, 
legs, and feet wholly yellow, the last gradually infuscated toward 
the end. The fore coxae have three large bristles, numerous black 
hairs, and a few smaller bristles. Middle coxa3 with hair and 
bristles. Hind coxaj with the usual bristle. Fore tarsi widened 
from near the tip of the first joint, the under surface destitute of 
the customary black hair, therefore resembling a broad yellow sole. 
All the joints beyond the first are shorter than usual. Hind meta- 
tarsi shorter than following joint. Wings subhyaline, of slender 
outline. Fourth vein converging with the third in its last section, 
less so near the tip, ending distinctly before the apex. Posterior 
cross-vein at right angles to the long axis of the wing. 

5 . Face wider, less narrowed in the middle, without groove ; 
but little white pollinose, except ou the prominent lower part, the 
remainder more greenish or brownish. Palpi a little larger, each 
with a minute bristle as well as fine hairs. The black spot over- 
lying the transverse suture on each side of the thorax is very large, 
rather more so than the male. In one immature specimen the 
coppery colour is but little noticeable, leaving the abdomen and 
scutellum almost pure green.

apical half brown ; arista dorsal, black, short, curved, distinctly 
feathered with sparse hairs. Cilia of inferior orbit white. Thorax 
shining green, with a bronze median line extending to the scu- 
tellum ; anteriorly this line is enclosed by the acrostichal bristles ; 
the small humeral bristles occupy a large area. The usual black 
colour accompanies the transverse suture on its upper side. In the 
proper light there is a silvery pollinose spot behind the humerus, 
another above the root of the wing, and a third behind it. Pleurse 
blackish-green, white-dusted. Cilia of tegulaj black. Abdomen 
shining green, the sides of each segment silvery pollinose ; each 
incisure is covered with a broad black band. Hypopygium black, 
exserted, the peduncle nearly as long as a segment of the abdomen ; 
lamellae small, dark-brown, with slender cilia, and on the upper side 
a row of equal short spines. Front coxfe yellow ; middle ones 
brown, except the tips ; hind ones yellow, with browu base. The 
front and middle ones have numerous black hairs ; the former have 
several bristles, the latter only one of any size ; hind coxae with a 
single lateral bristle. Femora and tibiae yellow ; the middle 
femora with a row of delicate, short, light-colouied cilia below. 
Middle and hind femora with preapical bristle. Tarsi yellow, the 
middle and hind ones infuscated toward the tip. Fore pulvilli 
enlarged ; hind metatarsi shortened. Wings slightly infuscated ; 
the last section of the fourth vein bends gently forward, runs 
nearly straight for a distance, then is gradually recurved, ending 
near the third, which bends back at tip.

Antenna3 blackish, the lower side reddish to a variable degree. 
Third joint short when fully developed, in some specimens shrivelled. 
Arista plumose, short, thick at base, rapidly tapering. Cilia of 
inferior orbit whitish. Thorax dark green, but little shining, 
acrostichal bristles in two rows, enclosing an area which is opaque 
as far as the middle. On each side of this, reaching to the inner 



314 Professor Aldricli on the 

dorsal bristles, is a more shining dark-blue area changing to violet 
posteriorly, and also spreading wider, so that most of the posterior 
half of the dorsum is deep violet. Viewing the specimen from 
above and behind, the light striking it from above and in front, 
four silver spots are visible — two just below the transverse suture, 
and behind the humeri, the others above and behind the roots of 
the wings. Scutellum bronze-green. Pleurse green, white-dusted, 
tegulaa light-yellow, their cilia black. Abdomen bronze-green 
above, brighter green on the sides, below the middle of the sides 
white poUinose. Sixth segment entirely silvery pollinose, rather 
thin dorsally. Hypopygium large, blackish-green, considerably 
dusted, sessile, the lamellee developed into rather long upcurved 
black processes, irregular in outline and with numerous black 
bristles of different sizes ; at the base of each of these processes, 
below (dorsad) is a minute, yellowish, yellow-haired appendix, 
— this I take to be the true lamella, homologous with that 
organ in Dolichopus, while the process just described is a develop- 
ment from its upper basal corner, as occurs in some other species of 
the family. Fore coxse yellow, at the base very slightly inf uscated, 
with black hairs and bristles, middle and hind coxaj brownish-black, 
rather largely yellow at apex. Femora and tibiae all yellow, the 
middle and hiud knees very slightly infuscated, middle tibiae 
slightly, the hind ones strongly infuscated at tip. Front tarsi

bristles and two small ones, its disk large. Abdomen short, for 
a male, tapering, the posterior margin of each segment, with a row 
of large bristles, which are longest on the last segment. Hypopy- 
gium disengaged, large, bent forward under the abdomen, the 
lamellae rather small. Fore and middle coxas with bristles and 
hair on the front side ; the hind ones with two bristles on the 
outer side. Middle and hind femora with a pre-apical bristle. 
Hind metatarsus without bristles above. Second and third longi- 
tudinal veins straight, moderately divergent ; fourth curving 
abruptly forward about the middle of its last segment, then gradu- 
ally curving in the other direction, so that near the extremity it 
has a concavity behind, ending near the third vein. Posterior 
cross- vein a little more than its length from the margin. 

1. Leptocorypha ])avo, n. sp. (PL XII., fig. 112, wing.) 
$ . Bright, metallic-greeu. Front wide, bright-green, a little 
concave. Face moderately narrow, wider above, covered with a 
smooth coat of whitish pollen. Palpi but little visible, yellow, 
with only one or two very minute bristles. Cilia of the inferior 
orbit whitish, no long hairs behind them. Occiput flat. Antenna 
large, reddish, first joint hairy above, broad at the end, drawn out 
on the inner corner into a cone ; second joint transverse, hairy 
above ; third joint very large. Viewed from the side, the last on 
its proximal, lower corner runs back entirely past the second joint. 
It is very high, rounded above, the arista dorsal rather short and 
stout with long pubescence, the lower distal portion of the joint 
drawn out into a long up-curved point, densely short, pilose on 
the inner and lower side. It reaches about to the middle of the 
arista, and beyond its end the latter has longer pubescence than 
before it. This third joint in outline is similar to that of some 
species of Tahanus. Thorax very bright metallic-green, somewhat 
whitish-dusted about the front part. The triangular areas of fine 
bristles above mentioned are on a bronze ground colour. Trans- 
verse suture very far forward, a black spot along its upper side. 
Scutellum long, nearly rectangular on its disk. Pleurse mostly 
black, dusted lightly with white, around the base of raiddle and 
hind COX93 more or less yellow. That thin fold of the integument 
which, in many species of this family, begins just above the hind 
coxae and expands upward, so as to partially embrace the first 
abdominal segment, is strikingly conspicuous in my specimens of 
this species. Halteres and tegute yellow. Cilia of the latter 
black. Abdomen bright-green, a narrow line of black along the 
posterior border of each segment, numerous black hairs and a

posterior row of long bristles on each segment. The bristles of 
the fifth segment are a little longer than the segment. The exserted 
hypopygiam is large, yellow throughout, except that the pedicel 
is brownish at the base, and the lamellaj are bordered with brown- 
ish. Bristles of the latter yellow, comparatively weak. Coxte, 
femora, and tibise all yellow. Tarsi yellow at base, uniformly a 
little brownish toward the tip, on account of the covering of 
minute dark hairs. Pulvilli of ordinary size. Venation of the 
wings are in the description of the genus. Length 3'25 mm.; of 
wing, 3 mm.

$ . Thoracic dorsum shining green. Abdomen yellow and 
black. Legs yellow. Front very short, opaque, greyish. Face 
white, long, so narrow as to be almost invisible, stni the eyes in 
well-preserved specimens are not contiguous ; just below the 
antenna the face widens. Antennae brownish or yellowish, long ; 
the first joint elongate, with a few hairs above ; the second and 
third of about equal size, the latter with a blunt point directed a

POLYMEDON. 

Osten Sacken, Western Diptera, 317, 1877. 

This genus will have to be somewhat amended, as it 
should evidently include the following species. Baron 
Osten Sacken, in establishing it, had only one species, 
and consequently did not succeed in separating per- 
fectly the generic and specific characters. The long cilia 
of the tegulte, absence of acrostichal bristles, and large 
swelling of the costa, are characters that pertain only to 
the male of P. flabellifer, and are not generic. In the 
species here described, the hind metatarsi are in the male 
decidedly, in the female slightly, shorter than the follow- 
ing joint. Mr. Samuel Henshaw, at my request, kindly 
examined the types of P. flabellifer in the Museum of 
Comparative Zoology, Cambridge, Mass., and informs me 
that the hind metatarsi are not shorter than the following 
joint. 

In the generic diagnosis, add " above " to the clause, 
" First joint of hind tarsi without bristles." 

1. Polymedon siqjerbus, n. sp. (PI. XI., fig. 103, head 

of $. PI. XII., fig. 113, wing; fig. 118, head of 

? ; fig. 119, head of 6.) 

$ . Head large and high. Face wide ; about half-way to the 

lower corner of the eye it is bent backward obliquely and grows 



Dolicliopodidai of St. Vincent {West Indies). 319 

gradually wider ; beyond the lower corner of the eye it hangs 
down in a thin sheet, rounded below, about as far as its own width. 
The mouth parts hang down behind this. The whole face is 
silvery white. The proboscis and palpi are brown. Front some- 
what excavated, deep metallic-blue, approaching violet in colour, 
very slightly dusted in the middle ; along each side and across 
behind the ocelli white pollinose. Antennae situated far above the 
middle of the face, directed strongly upward, as compared to the 
head alone ; the latter, however, stands in an oblique position, 
strongly receding below, so that the antenna3 are in reality directed 
straight forward. Immediately below their origin there is an 
angle in the profile of the head, and it begins to recede. First 
joint of the antennae long and slender, yellow, with hairs above, 
the second projects considerably in a rounded curve over the inner 
edge of the third ; it is also yellow. Third joint large rounded, a 
little longer than high, with a slight point. The arista is dorsal, 
thick, short, nearly bare, curved downward, brown in colour. 
Third joint of antennte brown at the tip. Cilia of inferior orbit 
white. Occiput dark-green, dusted on each side. Dorsum of 
thorax shining metallic-green, in an oblique view, more blue or 
violet, darker and more bluish near the borders. Acrostichal 
bristles two rowed ; a considerable area of small humeral bristles. 
The transverse suture is wholly bronze-black, which colour extends 
narrowly toward the anterior. Just below this is an elongate 
silvery pollinose spot, reaching forward to a point above the 
humerus. Pleurte greenish- black, covered with bluish white dust. 
Tegulfe infuscated, with black cilia. Hal teres yellow. Scutellum 
shining bluish-green, with a very large and a very small bristle on 
each side. Between the corner of the scutellum and the root of 
tlie wing is an excavated area, black, with a handsome silver spot. 
Abdomen bluish-green, with rather long bristles bordering the 
segments behind. When viewed in the proper light, each segment 
beyond the first is white pollinose on the anterior half, except in 
the middle of the dorsum. Toward the venter this pollen becomes 
dense and silvery. In the same light the posterior half of each 
segment is deep metallic violet-blue. Hypopygium large, exser ted, 
turned under the venter. It is opaque-black, except some of the 
inner parts, which are brownish or yellowish. The lamellae are 
large, parallelogram shaped, somewhat oblique, black. Along 
the upper margin of each are two slender curved yellow bristles, 
some distance apart. Fore and middle coxse with a few hairs and 
bristles ; hind ones with a single lateral bristle. Fore coxaa yellow, 
the others brownish-black. Femora and tibiae yellow. Tarsi 
blackened from the middle of the first joint, middle tarsi a little 



320 Professor Aldrich on the 

crooked near the middle. Hind metatarsi three-fourths the length 
of the following joint, with a small but distinct bristle on the 
underside. Wings a little smoky ; venation much as in Tachy 
trechus (Loew, Mon. N. A. Dol., PI. III., 6) ; the third vein, how- 
ever, is bent backward by a very gentle curve, beginning before 
the middle of the wing ; the fourth vein runs in a straight line 
past the cross- vein for a distance about equal to the length of that 
vein, then bends forward in a gentle curve and is almost straight 
for the rest of its course, but with a slight convexity forward. It 
ends some distance before the apex, near the third vein. Costa 
scarcely swollen before the end of the first vein. Fifth vein 
attenuated near the end, obsolete before the border. 

5 . Face white poUinose of about the same width as in the 
male, ending in a point below, which reaches fully to the lower edge 
of the eyes. Palpi and proboscis rather small, brownish. First 
joint of the antennae shorter than in the male, all the joints 
blackened along the upper border. Middle tarsi simple ; hind 
metatarsi but little shorter tlian the following joint. General 
colour of thorax and abdomen deep blue, verging into green, 
shining. 

Length 4—4-75 mm. ; of wing, 4-'2 mm. 

Eleven males and eight females ; one label reads, 
"Richmond A^alley, Forest. 1800 feet, December 31. On 
stones along stream ; " another, " This species lights on 
rocks in the beds of mountain streams above 1000 feet. 
Very warj." 

The green, blue, and silver colours of this species are 
so changeable in different lights that they are difficult to 
describe. There will be no difficulty in recognizing the- 
insect. 



DiAPHORUS. 

Meigen, Syst. Beschr., iv., 1824. 
1. Diaj)horus opaciis, Loew. 

This species was based by Loew on a single male 
specimen from New York, and a female froTn Pennsyl- 
vania was doubtfully referred to it. The length of these 
specimens is 3 mm. I have numerous representatives 



Dolichopodidfe of 8t. Vincent (West Indies). 321 

of a species from St. Vincent, West Indies, which agree 
substantially with the description, but are only 2 mm. 
long ; in the males also the hairs on the underside of the 
middle femora seem to be less conspicuous. It would 
not be safe to describe the species as new without com- 
parison with the types of opacus ; for the pi'esent I 
consider it a small form of the latter. 

In the West Indian specimens, it is difficult to separate 
Diaphorus from Chrijsotus. When the face and front 
are parallel, I have followed the general rule of referring 
all to Chrysotus that did not show in the male sex 
elongated front pulvilli or large bristles at the end of 
the abdomen. 

2. Diaphoriis approxlmatus , n. sp. 

$ . Face white pollinose, rectangular, the ground colour 
blackish ; the eyes approximated on the front so as almost to 
touch, the two frontal triangles and the narrow strip connecting 
them whitish pollinose. Antennaj short, third joint crescent 
shaped, with apical arista ; second joint with several radiating 
black hairs of moderate length. Cilia of inferior orbit white. 
Dorsum of thorax green, dusted with yellow, not very shining ; 
pleura black with grey dust. Halteres and tegulas yellow, the 
cilia of the latter brown, sometimes a little mixed with white. 
Abdomen shining dark-green, with black hairs above, which change 
to reddish on the sides ; hair of the venter long, delicate, pale. 
The four bristles at the apex of the abdomen are small. Hypopy- 
gium concealed. Coxae black ; femora brownish-black, yellow at 
tip : on the outer and lower edge of the fore femora, near the tip 
is a row of long hairs. Tibiae yellow, tarsi infuscated from tht 
tip of the first joint, pulvilli of fore tarsi enlarged. Wings 
slightly brownish, very broad ; the greatest width is about the 
middle ; the third vein toward the tip curves noticeably backward. 
Length 3 mm.; of wing, 2*5 mm. 

Numerous males. Sea level to 1000 feet. May. The 
tegular cilia seem to be pale in some lights and brown 
in others. 

3. Biapliorus parvulus, n. sp. 

Minute, shining green ; legs yellow ; cilia of tegula, and of 
inferior orbit pale ; eyes of male broadly separated.

half or more blackish ; hind tibiae yellow with dark base. Femora, 
tibiae and tarsi yellow, the last one or two joints of the tar^i 
infuscated ; the femora sometimes have a brownish tinge. Fore 
tarsi one and a-half times the length of the tibia3, with enlarged 
pulvilli ; the other pulvilli of equal size scarcely enlarged. The 
erect lateral bristle of the middle tibiae very large. Wings 
yellowish, with yellow veins and the usual configuration. 

9 . Antennae, particularly the third joint, smaller. Pulvilli 
plain ; otherwise as in the male. 

Length 1 -2 mm. ; of wing, the same. 

Three males, three females, 1500-2000 feet. May, 
July. 

4. Diaphorus dimidiatus, n. sp. 

Light green, whitish pruinose ; basal half of abdomen yellow. 

(J. Face and front concolorous, bluish-green with grey dust ; 
lower part of the face rather narrow, palpi rather large, pale 
yellow, with black hairs; antennte blackish, third joint very short, 
with dorsal arista ; cilia of lateral and inferior orbit pale, the 
lower ones long. Thorax light green, somewhat bluish, wholly 
pruinose with white ; in the middle of the dorsum a little shining ;

almost the same size. Middle tibiae on the outer front edge with 
two bristles besides the one at the tip ; hind tibias slender, with a 
few small bristles behind. Wings rather narrow, subhyaline, with 
yellow veins. The anterior end of the large cross-vein is in the 
centre of the wing. Length 2 mm.; of wing, 1"8 mm. 

Five males. May. This species belongs to the group 
of D. lioffmanseggii, Meig., of Europe, and D. satrapa, 
Wheeler, of Nebraska, but is readily distinguished by 
the characters given.

middle tarsi scarcely longer than the tibiae, the pulvilli small ; all 
the tarsi infuscated from about the third joint. Wings very 
broad near the base on account of the extraoi'dinary development 
of the anal angle ; first vein farther from the margin than 
usual. 

$ . Face and front of equal width, the face remarkably broad 
and short, greyish brown : the large palpi of the same colour ; 
front opaque-brown ; front femora destitute of long hairs ; bristles 
of posterior tibife stronger than in the male ; wings, although very

proboscis blackish, the former of ordinary size. Thorax bronze- 
green, a little shining : the pleurte blackish, with white dust, more 
conspicuous posteriorly ; halteres and tegulfe yellow, the tegular 
cilia black. Abdomen bronze-green with a coppery reflection,

Wackish hairs in front, hind coxte with a single lateral bristle ; 
near the end of each femur, on the outer side, are three or four 
larger hairs ; on the anterior side of the middle tibia just below 
the knee, is a single erect bristle, on the posterior side of the hind 
tibifB are two or three small bristles. The pulvilli of the fore 
tarsi are enlarged ; fore and middle tarsi infuscated from the tip 
of the iirst joint, the length of the former exceeding that of their 
tibite ; hind tarsi shorter than their tibias, the inf uscation beginning 
near the base. Wings of only ordinary width, subhyaliue, the

Numerous males and females. 500-1500 feet altitude. 

This species differs from sodalis, Loew, by its smaller 
size and black hairs on the fore coxEe. The female of 
duhius differs from the male in having a slightly wider 
face, smaller antennas, shorter and thicker abdomen, the 
femora without longer hairs, and the tibite with stronger 
bristles. In a large series of specimens I notice con- 
siderable variation : some of the specimens if alone 
would no doubt be referred to Glirysotus. 

Chrysotds. 
Meigen, Syst. Beschr., iv., 1 824.

■enlarged facets ; front broad, short, deep bluish-green to bronze- 
green in colour ; palpi and proboscis blackish. Antennae black, the 
third joint very large, kidney-shaped, hairy along the outer part ; 
arista apical, arising from a deep notch in the joint. In some 
specimens this peculiarity is but little developed ; in others it is 
very distinct ; in some specimens the point below the notch is 
longer than the one above, giving the arista a subapicai position. 
Cilia of inferior orbit small, brownish. Dorsum of thorax 
bright bluish-green, sometimes more bronze or coppery ; pleura 
black ; tegulee and halteres yellow to brown, the former with black

Seven males, numerous females. May and July. 
500-2000 feet altitude. 

The females of this species so closely resemble those 
of Diaphorus favipes, that they can scarcely be 
separated, I could find no distinct difierences. 

11. Chrysotus apicalis, n. sp. 

^. Front shining green, wide ; face of same colour with a 
little pollen, narrowed in the middle, owing to an area of enlarged 
facets in the eye ; eyes somewhat emarginate at the level of the 
antennsB ; palpi yellow ; antennae black, the first joint bare, this 
and the second of ordinary structure ; the third joint crescent

shaped, in its vertical diameter very large, on the apical side near 
the middle suddenly drawn out into a long, narrow point ; arista 
inserted just before, or in some cases almost exactly at, the apex 
of the prolongation, moderately long, pubescent ; the whole inner 
and lower surface of the third joint is light pilose. Cilia of the 
inferior orbit white, a considerable amount of long white hair 
behind them. Thorax golden-green on the middle, more or less 
covered with pollen, around the margins more pollinose ; acrosti- 
chal bristles few, in two rows ; the small humeral bristles number 
only about half-a-dozen on a side ; about the base of each large 
bristle is a black dot. Pleurae greenish-black, dusted with white. 
Tegulee and halteres light yellow, cilia of the former whitish. 
Abdomen dark green, more or less thickly dusted, sometimes with 
a bronze reflection. Seen from above, the first segment is very 
broad with parallel sides ; the rest are successively narrower, 
rapidly tapering. The green colour ends with the fifth segment, 
the following one is black. From the side, the abdomen is slender 
the dorsum and venter nearly parallel to the fifth segment. The 
following two are somewhat excavated on the under side, but only 
the tips of one or two small organs are visible. Coxaj black, 
about the apex sometimes slightly yellowish. The front and 
middle ones with a few black hairs and bristles on the front side ; 
hind ones with one lateral bristle. Front and middle femora 
yellow, with more or less of a blackish tinge along the upper side. 
The middle ones are lighter-coloured than the front ones. Hind 
femora wholly greenish-black. All the tibia3-yellow, tarsi-yellow, 
gradually infuscated from the tip of the first joint. Pul villi of 
ordinary size. In one single specimen out of fifty examined there 
is, on the middle of the lower surface of one of the hind 
metatarsi, a slender erect bristle. This is probably abnormal. 
Venation normal, the same as figured by Loew for C. obliquus 
(Mon., N.A. DoL, PL VI., 31). 

5 . Face rather wide, not narrowed in the middle ; this and the 
front often with a steel-blue reflection, somewhat dusted with 
white or yellowish. Below the middle of the face the contour is 
interrupted by a suture, except in the middle ; below this the face 
is more prominent. The oral cavity and the proboscis are much 
larger than in the male. Palpi large, flat, yellow, sometimes 
brownish, with white or yellow pollen. Proboscis projecting 
below the head, black. Antennae as in the male, but the third 
joint not at all drawn out, simply crescent -shaped, at most a little 
triangular. Arista apparently apical. Behind the orbital cilia 
but a few hairs. Colour of thorax and abdomen more opaque than

yellow at base and tip. 

Length 2 mm.; of wing, I'S mm. 

Numerous specimens. Sea level to 1000 feet. May. 

ASYNDETUS. 

Loew, Centur., viii., 58, 1869. 

1. Asyndetus frcdellus, n. sp. (PL XII., fig. 114, tip of 

wing.) 

^ . Green, thickly dusted, not shining except on femora and 
slightly on abdomen. Face very broad, the sides parallel, covered 
with opaque, whitish dust. Palpi rather large, with black hairs 
and whitish-dusted. Front very broad, like the face in colour but 
a very little less dusted, showing more of the underlying green. 
Anteunse black, short, the second and third joint together nearly 
circular in outline. Arista dorsal. Orbital cilia black above, 
white below. Thorax heavily dusted with brownish, not at all 
shining, a single scattering row of very minute acrostichal bristles. 
On each side of the broad, median dorsal stripe is an ill-defined, 
light-blue dusted stripe, so that the brown colour appears to form 
three broad longitudinal bands, the lateral ones so wide as to 
extend down over the pleurae for some distance, the blue colour 
reaches the corners of the scutellum, and the latter is wholly blue, 
except a narrow trace of brown along the posterior border. It has 
two large bristles. Pleuras brownish above, fading into light blue 
below. Tegulee yellow, their cilia whitish. Halteres yellow. 
Abdomen moderately elongate, tapering, green, but little shining. 
Behind each incisure the colour is deep blue and more metallic. 
The hair of the abdomen is black, and conspicuously coarse and 
long. Hypopygium small, embedded, with four bristles pointing 
backward. These are about as long as the fifth segment. Legs 
robust, black, bristly, the coxaj whitish from the overlying dust, 
front and middle ones with numerous bristles on the front side, the 
hind one with a single lateral bristle. Femora all somewhat 
thickened, dark green rather shining, with rows of moderate 
bristles on the under side. These structures are not raptorial, 
since they are rather weak and the tibiae lack the corresponding 
development. Knees narrowly yellow. TibijB fuscous, the front 
ones a very little lighter, simple," with strong bristles. Tarsi 
black, simple. Pulvilli of all the feet much elongated, yellow. 
Wings slightly greyish, fading into hyaline posteriorly and

apically. The first longitudinal vein ends about one-third of the 
way to the apex. Its end is a trifle beyond the large cross-vein. 
Second and third veins close together diverging uniformly through 
their whole course, the latter ending rather far from the apex. 
The costal vein ends with the third longitudinal instead of con- 
tinuing to the fourth. The fourth longitudinal vein becomes 
gradually weaker beyond the posterior cross-vein for about three- 
fifths of its course. It then curves suddenly forward for a short 
distance, curves back again into its original direction, and ends in 
the apex. The whole portion beyond the first curve is very deli- 
cate and transparent, and sometimes the section running forward 
is entirely obsolete. 

$ . Face scarcely wider than the male. Pulvilli of usual size. 
Abdomen even less metallic than in the male, without the terminal 
bristles, otherwise appearing much the same. The tibiae and tarsi 
are sometimes lighter in colour than in the other sex. 
Length 2-3 to 2-5 mm. ; of wing, 2 mm. 

Eleven males and twenty females. Several specimens 
are labelled " May," and one " Seashore." 

This species is closely allied to A. interrupt us, Loew, 
but the latter is over 5 mm. long. The colour of the 
thorax seems by the description to be different also.

face green, brownish dusted, but somewhat silvery pollinose from 
above, a very little narrowed in the middle. Palpi yellow, with 
long black bristles, proboscis black. Antennse black, very short? 
the third joint crescent-shaped, hairy, with a long slender sub- 
apical arista. Cilia of the inferior orbit and another row behind 
them white. Thorax metallic-green brown-dusted. Acrostichal 
bristles in a single row. Eight or ten small humeral bristles. A 
brownish- black stripe along the transverse suture, running forward 
to the humerus. Just below, a spot is silvery when viewed from 
above. Pleura green, white pollinose, more silvei-y from above. 
Halteres and tegulse yellow ; cilia of the latter yellowish. Scu- 
tellum with the usual small and large bristles ; between the 
scutellum and wing is a concave area, black, with a silvery spot.

First joint longer than the following one, on its under surface with 
a long slender upright bristle. Front pulvilli a little enlarged. 
Wings large, wide toward the apex, yellow before the third vein. 
The first and second veins are rather far from the costa, and enter 
it at a less acute angle than usual. The third vein runs close to 
the second to its end, then turns with a strong curve backward, 
reaching the margin just before the apex. The last section of the 
fourth vein in the shape of a gentle double curve, ending just 
behind the apex. 

$ . Front as in the male. Face rather wide, the suture distinct, 
less pollinose than in the male. Hind metatarsus without the

inferior orbit delicate, of a whitish colour. Dorsum of thorax 
yellow in front, the posterior part and scutellum shining light- 
green. Acrostichal bristles two-rowed. The green colour extends 
forward about to the transverse suture. Farther than this it 
extends only in three fading and irregular streaks. Laterally it 
does not reach the bases of the wings. Pleurce plain yellow ; a 
dark spot below and one behind the wing. Cilia of tegulae 
yellowish. Metanotum yellow. Abdomen blackish, not shining, 
more brownish at the base, scarcely tapering. Hypopygium almost 
wholly concealed, the length of a few scattered yellowish bristles

yellow. Legs and feet as in the male, except that the pulvilli of 
the front feet are of the normal size. Wings but slightly yellow. 
Veins straight and almost uniformly divergent ; only in the 
second there is an almost imperceptible trace of two siuuations, at 
the places where these occur in the male. This vein ends nearer 
the apex than in the male.

almost contiguous. Antennte short, third joint a little pointed, 
with an apical, or perhaps subapical, arista. Front wide. Thorax 
and abdomen blackish, non-metallic. Hypopygium concealed, but 
rather large, hence the abdomen scarcely tapering. Legs dull

siderably darker than the perfect specimen here 
described. 

2. XantJwtricha minor, n. sp. 
Resembles the preceding, except in the following respects : 
The general colour is somewhat darker, the venter and sixth seg- 
ment not yellow, male hypopygium blackish, the delicate parts 
shrunken and difficult to make out, but apparently without the 
long filaments so characteristic of the preceding ; pleura wholly 
bluish black ; the posterior cross-vein is shorter, in consequence of 
the fact that the fourth vein bends back to meet it, forming a 
distinct angle at this point. The last character is sufficient to 
separate the two species. Length 1-2 mm. 

One male^ two females. 500 feet. 

3. Xanthotricha singularis, n. sp. 

Still a third species of this minute genus differs from the first 
in its extremely small size, in its colour, which is in general the 
same as the second, and in the singular structure of the male 
hypopygium. This bears a close resemblance to the ovipositor of 
a female, extended to its full length and bent under the abdomen. 
Only by using a power of several hundred diameters could I 



DolicJiojwdidx of St. Vhicent (West Indies). 341 

ascertain that this structure ideally belonged to a male instead of a 
female. The females of the species, however, do not have such 
extended ovipositors ; so the resemblance is rather to what one 
might suppose the female to be than to the female itself. Thi3 
hypopygium is black, minutely yellow at tip. The wings of this 
species resemble those of the first, but are a little more rounded. 
Length 1 mm. 

Six males, three females. May. 500 feet.

and the hind margins of the abdominal segments bright-green. 
Cilia of tegulae yellow. 

$ . Face bright-green with thin white dust. Palpi and 
proboscis yellow. Front bright-green. Antenua3 yellow, very 
small, arista dorsal. Thorax yellow, the scutellum violet, a green 
stripe upon the dorsum of the thorax is as wide as the scutellum 
behind and tapers in front to a rounded point at the margin. 
Metanotum yellow. Scutellum with only one pair of large bristles, 
the outer pair being very small. Abdomen yellow, the first segment 
above with a very narrow green border behind ; the following 
three segments almost half green ; the fifth a little more than half, 
and the sixth entirely, green. Venter wholly yellow ; near the 
hind margin of each segment ai-e placed several large bristles. 
Hypopygium embedded, yellow ; only two small yellow, hairy, 
palpus-like organs are visible. Feet wholly yellow, the tarsi only 
moderately infuscated. Fore coxae on the front side with a single 
longitudinal row of minute black hairs, and about three bristles at 
the end. Front femora near the base with six short thorn-like 
bristles. Front tarsi nearly three times the length of the tibiae. 
Middle tibiae and metatarsi with two rows of close short cilia, one 
on the front and one on the upper side ; as these cilia project in 
nearly the same direction, the effect is like a single somewhat 
tangled row. Hind tarsi as long as the tibia3. All the legs are

■dorsal or subdorsal. Thorax bright green. Scutellum with two 
large bristles, the outer pair minute, oppressed, or absent. 
Pleurte green, white pollinose, the posterior border yellow. 
Tegulaj and halteres yellow. Abdomen green, the venter dorsum 
of first and proximal half of second segment yellow. Still in some 
■cases the posterior margin of the first segment green. On the 
lateral angle of the first segment one or two long black bristles. 
Remainder of abdomen with small sparse black hair. Legs in- 
•cludiug coxfe, yellow, the tarsi slightly infuscated. Fore coxa3 with 
three yellow bristles, hind with one. Fore metatarsus scarcely 
shorter than tibia, middle one but little shorter, whole hind tarsus 
four-fifths the length of its tibia. The legs have no bristles of 
any size ; at the tips of the middle and hind tibiae, and on the fore 
■side of the same near the base are very small ones. Wiugs 
hyaline, the veins yellow ; third vein recurved at tip, branch of 
fourth vein making a right angle at its origin. Posterior cross- 
vein oblique, two-thirds its length from the margin. Length 
1'8 mm. ; of wing, 2 mm. 

Three females. One specimen has the third joint of 
the antennge brownish-black, and the outer pair of 
«cutellar bristles visible though minute, the other two 
have the antenna wholly yellow, and no second pair of 
bristles whatever. This does not seem to indicate a 
specific diti'ereuce.

colour. Fore coxte with white hairs and two black bristles. All 
the femora with white cilia below, longest on the front ones 
near the base. Front tibite on the upper side with a row of four 
successively longer bristles, the last conspicuously long and two- 
thirds of the way to the end. Bristles of the other tibite incon-

black bristles. Middle and hind coxaB black ; the former with 
white hairs and one or two black bristles, the latter on the outside 
with a single black bristle and a few white hairs. Front and 
middle metatarsi longer than their tibias, the middle one with a 
dense row of short, blunt, slightly curved cilia on the upper edge.

wider above and below (the eyes almost contiguous in the middle), 
white poUinose, showing a little of the green ground colour below 
the antennae. Antennae small, yellow, arista dorsal. Front bright-

Volucella, sp. n. ? 

Three specimens belonging to the difficult group of 
fallens, vesiculosa, etc. I cannot find any description 
that will apf)ly well to the specimens. They differ from 
V. fallens, Wied., in the presence of a median and two 
lateral facial stripes, in the hair of the mesonotum being 
for the Taost part black, and in the presence of a large 
black spot on the scntellum. From both V. vaga, Wied.,

far given for this species is Nebraska, by Hunter ; the 
most southern one, Buenos Aires, by Lynch (Dipt.

A single female specimen, agreeing fully with the 
description of what Wulp thought was Weidemann's 
Syrphus exoticus. In the Biologia Centr.-Amer. I con- 
sidered Wulp's species doubtfully identical with A.fracta, 
O. S. Osten Sacken^s species, however, does not have 
the scutellum broadly black, as did the specimens Wulp 
described, and as does the specimen from St. Vincent 
now before me. Wiedemann does not mention the spot 
on the scutellum, and I doubt very much that it was pre- 



Blptera of St. Vincent {West Indies). 849 

sent in his specimen, as he could hardly have failed to 
mention it, so conspicuous is it. If his " schwarzlich 
Erzfarbe^^ means bright metallic green, or green-black, 
then there can be but little doubt that Osten Sacken's 
A.fracta is the same as A. exotica. In the work cited I 
mentioned a species from Mexico having an opaque, 
dark green mesonotum, which I thought might be the 
true A. exotica. Lynch is wrong in uniting it with the 
species having a shiniug mesonotum. 

Mesogramma. 

Loew, Centur., ii., 290, 1872. 

I have refrained from naming any of the numerous 
species (with one exception) that have been described 
from North and South America, in this genus, convinced, 
as I am, that their great variability will require a thorough 
monographic treatment, with abundant material, to 
certainly distinguish them. Many of the species are very 
abundant in warm, sunny places.

Ten specimens, labelled "Fitzhugh Valley, 500 feet, 
Cacao orchard." They differ very materially from the 
typical forms, but I believe that they represent a variety 
only. The female described by me in the work above 
cited certainly belongs with the males, though Giglio- 
Tos thinks that they differ too much to belong with them. 
The scutellum in these specimens has a narrow yellow 
border, and the abdomen is wholly red and yellow, the 
first segment alone excepted. There is a narrow, black- 
ish, pre-apical ring on the hind femora, and the hind 
metatarsi are brownish ; otherwise the legs are wholly

the face, and the abdomen has obscure blackish markings, 
in the shape of two slender, approximated, median stripes ; 
the hind margin of the segments is brownish. 

2. Mesogramma laciniosa. 

Mesogramma laciniosa, Loew, Centur., vi., 50. — Cuba. 

Several female specimens I refer doubtfully to this 
species. The third and fourth abdominal segments have 
each two oval, oblique, black spots, and the posterior 
bands with a geminate, anteriorly dilated, slender pro- 
longation in the middle, their anterior margin on each 
side concave; the fifth segment has three anterior, oval, 
black spots.

Loew, and he may be right.

third joint more or less yellowish at the tip, less produced than in 
P. aculeatus. Mesonotum shining, scarcely poUinose. Abdomen 
wholly shining black. Legs black ; the extreme tip of the femora, 
the base of the tibite, and the first three or four joints of the tarsi

JURINIA. 

E/ob. Desvoidy, Myodaires, o4, 1830. 

1. Jurinia, sp. (PI. XL, fig. 88a, antenna.) 
^ , $ . In structure and size almost identical with /. aimifera, 
Walk. Front shining black, through the rather thin pollen. 
Mesonotum shining green-black, very thinly pollinose. Tegulae 
deep brown. Abdomen deep blue-black throughout. Otherwise 
as in J. apicifera. 

This species is different from any that I know, either 
from North or South America, and may be new. Still, 
the wide distribution of the species of this genus renders 
it probable that it has been described from other regions 
in America.

Hah. South America ; Mexico ; West Indies. 

One specimen, which with much probability is con- 
specific with those from Cuba, referred to G. cMlensis, 
by Macquart. That the species is the same as G. ijallens 
is, to me, somewhat doubtful. It therefore seems worth 
while to give a better description of our specimen. 

$ . Claws small : sides of the face with bristles ; third joint of 
the antenna3 seven or eight times as long as the second joint. Front 
and face light yellow, silvery white pollinose, the sides of the 
front subtranslucent, as though oiled ; sides of the face with 
sparse, short, black bristles. Cheeks bare. Antennae black. 
Median depression of the face wider than the sides ; no bristles on 
its ridges. Dorsum of thorax grey pollinose, somewhat shining. 
Scutellum largely yellow. Abdomen narrow ; yellowish red ; first 
segment under the scutellum, second and third with a slender 
median stripe, and the posterior part of the fourth black ; pollen 
inconspicuous, except posteriorly. Tegular white. Wings sub- 
hyaline ; the costal, subcostal, and marginal cells markedly yellow ; 
veins elsewhere narrowly clouded with the same yellow colour or 
a dark brown. Claws and pulvilli small, not as long as the last 
joint of the tarsi. Length 1 1 mm. 

Phoroceea. 

Rob. Desvoidy, Myodaires, 131, 1830. 

1. Phorocera {Prospherysat ) puer, n. sp. (PI. XI., 
tig. 91, head of $ .) 

$ . Eyes very sparsely pilose, the scattered hairs visible only 
under careful examination. Front about as wide as the eye, the 
lateral, silver-grey margins narrower than the broad, brownish-red, 
median stripe ; the frontal bristles reach nearly to the base of the 
third antennal joint. First and second joints of the antennae red ; 
third joint black, four or five times as long as the second. Face 
and cheeks silver-grey, the lower part of the face and the cheeks 



Dij^fera of 8f. Vincent {West Indies). 355 

yellowish in ground colour. Mesonotum thickly grey poUinose, 
with five black stripes, the lateral ones interrupted. Abdomen 
flattened ovate ; shining black, with the anterior part of the 
second and third segments opaque grey; first segment without 
median bristles ; second segment with a pair of marginal ones ; 
third segment with a posterior row ; fourth segment bristly on the 
posterior half. Legs black ; claws elongate. Calyptrte white. 
Wings cinereous hyaline. Length 4i mm. 

One specimen. Prospherysa seems to differ from 
Phorocera only in the bare eyes, and the eyes of this 
specimen are, practically bare, so that it is a question 
whether or not this species should not be located in 
that genus. The cross-veins on the outer side of the 
wing are more than usually oblique, still hardly as much 
so as in Flagia. The genus Plagioprospherysa, Towns., 
which is synonymous with Proso-podes, B. and B., was 
based upon this character alone, and is to me hardly 
entitled to acceptance. 

EXORJSTA.

hyaline ; first vein with hairs throughout ; third vein with hairs 
as far as the small cross-vein : first posterior cell terminating near 
the tip of the wing, narrowly open, its angle obtuse and without 
stump. 

Twenty specimens. 

It will be seen from the generic synonymy given above 
that I take a different view of the value of tlie characters in 
this genus, from that of Messrs. Townsend, Bergenstamm, 
and Brauer. 1 am opposed to the principle that a genus 
is necessary for every described species in this family, 
•and refrain from here adding two more for the preceding 



358 Professor Williston on the 

species. It is with mucli regret that I reduce the above 
names to synonyms, for the worthy entomologist whose 
name they commemorate deserves better at the hands of 
his zealous confreres. 

There are now seven known species : — A. singularis , 
Towns. ; VanderiouJpia atro'phojwdoides, Towns. ; V. 
seqnens, Towns. ; Microchira mexicana, B. & B. ; Wulpia 
aperta, B. & B. ; and the ones described above — all 
markedly characterized by the rudimentary front claws 
of the female, and having the general markings and 
structure all very similar. No two, however, save per- 
haps the two species of Vnnderivulpia, agree in their 
structural characters. Townsend made the error, appa- 
rently, of mistaking females for males, describing the front 
claws as rudimentary in both sexes, while, without doubt, 
in all the species they are alone rudimentary in the female.* 
Perhaps a grouping of the described characters will bring 
out more clearly the value of those which have been 
used for distinguishing the genera. 

Eyes hairy. ^4. singularis, M. mexicana, A. Braiieri. 

Frontal bristles descending to the cheeks. A. singu- 
laris, A. Toiunsendi, A. Braiieri. 

Frontal bristles not descending below antennae. V. 
atrophopodeides, V. seqnens, M. mexicana, W. ap)erta. 

First posterior cell open. A. Braueri, W. aperta. 

First posterior cell closed in the margin or short 
petiolate. A. singuJaris, V. se.quens. 

First posterior cell long petiolate. V. atropJwpodoides, 
A. Toivnsendi. 

Costal spine present. A. singularis, M. mexicana, 
[V. aperta, A. Townsendi, A. Braueri. 

Male claws normal. A. Toivnsendi. 

Male claws elongate. A. Braueri. (Other males un- 
known.) 

Undoubtedly other mutations of these characters will 
appear among species yet to be made known. 

I will add, that, in the two males of A. Toionsendi, 
there is a single, well-developed orbital bristle; in the 
males of A. Braueri, there are none ; in all the females 
there are two. 

'■ Townsend has since recognized the males, and suspects that 
LacJuioinura, Towns., is also a synonym of this genus ( Trans. Amer. 
Ent. Soc, xxxii., 77, 1895).

(^ , 5 • Front broad, the median stripe scarcely one-third of its 
breadth ; at the upper corner of the eyes with two bristles, the 
inner longer one recurved, the outer one directed obliquely out- 
ward; a pair of proclinate ocellar bristles ; and two orbital bristles, 
the upper one reclinate the lower one proclinate ; on either side of 



362 Professor Williston on the 

the median stripe with about four or five rather strong bristles ; 
front of the female of the same width as that of the male, but 
•with two additional proclinate, orbital bristles. Third joint of the 
antennre not more than three times the length of the second, the 
arista moderately plumose on the basal half. Sides of the face and 
the cheeks bare, the latter with bristles on the lower margin. 
Mesonotum with well-developed centro-dorsal bristles extending 
in front of the suture. Scutellum with two well-developed bristles 
on each lateral margin, but without a marginal apical pair. Abdo- 
men short, oval ; second and third segments each with a pair of 
marginal bristles, the third with two additional lateral marginal 
ones, and the fourth with a posterior row ; hypopygium without 
bristles. Tibife without long hair, the bristles irregular. Third 
vein of the wings setulose at the proximal end, the distal section

Numerous specimens. St. Vincent. The present 
species does not wholly agree with the definition of the 
genus, as given by Brauer and Bergenstamm. It differs 
in having the first posterior cell open and inappendiculate,

1. Sarcophaga microjyygialis, n. sp. 

(J. Front above in width less than the length of the third 
antennal joint ; vertex with two strong proclinate bristles, a little 
in advance of the ocelli another, smaller, pair of reclinate bristles, 
apparently the beginning of the rather long ones composing the 
frontal rows ; ocelli with two proclinate bristles. Sides of the 
face narrow, not more than one-half the width of the median flat- 
tened surface ; a row of minute bristles near the ej'es, otherwise 
bare. The bare, hair-like tip of the arista about as long as the 
plumose portion. Cheeks with black hair, on the inferior 
margin with black bristles, reaching to the stout vibrissa, 
which are situated only a little distance above the oral margin. 
In colour, the sides of the front and face, the cheeks and the 
posterior orbits are light golden yellow, opaque central portion 
of the face grey ; frontal stripe and the antennae black. Black 
stripes of the mesonotum broad ; the mesonotum with black 
hair and with four rows of well-developed bristles, reaching 
to the front part. Scutellum with four stout bristles, and 
in the middle of the apical border a pair of minute bristles, 
closely approximated. Abdomen black, scarcely at all shining, 
the second and third segments each with four oval spots, some- 
what variable in different reflections ; third segment with a 
pair of median marginal bristles ; fourth segment with a strong, 
posterior row of bristles, and an oval black spot on each side 
anteriorly ; hypopygium small, black, grey or yellowish-grey 
pollinose, its first segment with a row of black bristles before its 
posterior margin. Legs black ; middle tibise with a single stout 
bristle on its posterior side near the middle; hind tibiaj with several 
bristles and without long hair on the inner side ; pulvilli long. 
Wings nearly hyaline ; first longitudinal vein without bristles ; 
third vein with bristles for more than half the distance to the 



364 Professor Williston on the 

anterior cross-vein, the latter situated at the middle of the discal 
cell; distance from the anterior cross-vein to the posterior cross- vein 
more than three times that from the latter to the angle of the 
fourth vein. Length 9 mm. 



2. 8arcoj)liaga concinnata, n. sp. 

^ . Agrees with 5. otiosa throughout, except that the middle and 
hind tibise are wholly without the thick long hair on the inner side, 
and the femora have less hair below. The specimens, moreover, 
seem to be less thickly haii'y than in that species, and the size is 
less. Length 9-11 mm. 

With tlie three specimens presenting the above char- 
acterSj there are four females which may belong with 
them, but from their larger size, I suspect are S. otiosa. 
The front is broader than in the males ; there are four 
well- developed bristles along the orbit and two orbital, 
proclinate bristles ; the black stripes of the mesonotum 
seem a little narrower; the fifth abdominal segment is 
red, the legs are without the long hair, and the claws are 
a little shorter. It is possible that the species is 
identical with 8. chrysostoma, Wied. 

3. Sarcoj^haga otiosa, n. sp. 

^ . Front narrow above, at the vertex the width is about equal 
to the length of the third antennal joint ; at each superior angle of 
the eyes there is a stout bristle directed backwards ; a little way in 
front of these there is a siugle, smaller bristle on each side ; along 
the edge of the frontal stripe, a row of thick-set bristles, short 
above, but becoming successively longer below. Sides of the face 
bare, except a row of minute bristles situated close to the eyes. 
The antennae reach nearly to the stout vibrissse ; arista long and 
densely plumose. Cheeks light-golden pilose, with a row of black 
bristles on the inferior margin, reaching to the vibrissce ; vibrissas 
situated at some distance above the oral margin. In colour, the

broad, with a black stripe. The wings show a noticeable 
difference in that the posterior cross-vein is at right- 
angles to the fourth vein, and is a little shorter than the 
penultimate section of the fourth vein. In the males 
described above the anterior angle of the discal cell is 
distinctly less than a right angle, and the posterior 
cross-vein is longer than the penultimate section of the

this species that I believe the determination is sufficiently 
certain. 

Calobata.

1. Calohata angulata. 

Calohata angulata, Loew, Centur., vii., 87 ; Schiner, 
Reise der Novara, Dipt., 253, Brazil, Colombia 
(Schiner, Loew). 

In the present collection there are about twenty 
specimens which were thought at first sight to be 
conspecific. A more careful examination, however, 
disclosed trustworthy specific differences. Both of 
the species are evidently closely allied to G. lasciva, 
Fabr., and it is not improbable that they have been 
confounded with that species. I do not know G. lasciva, 
but they differ, according to Schiner, in the light-coloured 
bands of the hind femora being oblique. Schiner 
thought that C. angnhita might be identical with 
C. annidata, P., but, if my determinations are correct, 
he was in error. In the present species the front is 
very narrow and long, distinctly less than one-third of 
the width of the head. The front tarsi are white from 
near the middle of the metatarsi, the terminal joints 
scarcely perceptibly darker. The lighter-coloured por- 
tions of the wing are subhyaline, and the first posterior 
cell is narrowly open The head is reddish-yellow with a 
small dark-red or black spot in the middle of the front. 
The antennae in all our specimens are more reddish than 
black. I have compared specimens from Brazil in my 
collection, and find no differences.

a broad front, distinctly more than one-tliird of the width 
of the head, brownish-red antennae, a rather narrow 
clypeus, stouter and rather longer front tarsi, with only 
the second, third, and fourth joints light-yellow, the 
lighter coloured parts of the wing more pure hyaline, and 
the first posterior cell closed. 

The genus Calohata has been repeatedly subdivided 
by Macquart and Kondani, but their subdivisions have not 
been accepted by later writers. For C. lasciva (G. 
alhimana, Macq.) Macquart proposed the genus Txniap- 
tera, but afterward withdrew it. For the same species 
Rondani proposed Grallopoda. For the species with open 
first posterior cell, bare arista and long anal cell, he pro- 
posed Mimegralla ; for those with closed first posterior 
cell, bare arista and long anal cell, Grallomyia; while 
Kaineria, which was afterwards changed to Tanipoda, 
was applied to species differing from G-rallomyia in the 
short anal cell. Calohata he restricted to those species 
with plumose antennal arista.

A single specimen which agrees with the description 
in everything save some of the wing-markings. The 
brown bands of the wings have blackish clouds continu- 
ing them to the hind margin, and there is a distinct 
hyaline interval in front of the second vein between the 
third and fourth bands. 

3. Eiixesta, n. sp. 

A single specimen of a small species differs from all 
known to me of those having four bands, in the 
possession of a rounded hyaline spot in front of the 
second vein and beyond the third band. The purely 
hyaline interval is situated beyond this spot, and is 
narrow ; the apical band is narrow, and the brown of 
the broad second band scarcely exceeds the third vein, 
but is filled out to the hind margin by a strong blackish 
cloud. The species is small, the front is brownish-red, 
the antennae, front cox^e and metatarsi are yellowish. It 
is labelled " Southern end of the island. Open ground 
near sea, on herbage. May.^'

narrowly whitish ; the vertex and the upper part of the orbits, 
blue ; hair black. Antennae brownish-yellow, the third joint oval. 
Face considerably excavated, and, together with the clypeus, steel- 
blue, shining, the upper part poUinose ; cheeks reddish. An arcu- 
ate band extending across the middle of the mesonotum has a 
more blackish reflection. Coxae and femora light yellow ; front 
tibiae and tarsi black ; the four posterior tibiae and the distal 
joints of their tarsi brown, their basal joints yellow or yellowish. 
Wings hyaline ; the costal and subcostal cells throughout, a small 
spot in the extreme proximal end of the submarginal cell, and a 
small spot beginning at the extreme tip of the marginal and ex- 
tending across the submarginal into the first basal cell, uniformly 
dark brown ; fourth vein distinctly curved forward, narrowing the 
first posterior cell ; the fifth vein reaches the margin of the wing ; 
first section of the ovipositor a little longer than wide, distinctly 
longer than the last abdominal segment, yellowish at the base ; 
abdomen for the most part black. Length i-i^ mm

1. Epiplatea amabilis, n. sp. 

5 . Front moderately broad, slightly narrower above, opaque 
yellowish-red, with short black hairs. Face shining translucent 
reddish-yellow ; gently excavated under each antenna ; nearly 
vertical and straight in profile. Frontal, facial and occipital orbits 
narrowly silvery-white. The clypeus forms a narrow, horse-shoe 
shaped body, not projecting in profile. Antennae reddish-yellow ; 
third joint elongate oval, not reaching quite to the lower margin of 
the face ; arista black, bare. Proboscis stout ; palpi slender, 
yellowish, except at the base. Mesouotum uniformly yellowish- 
red (about the same colour as the front) ; scutellum somewhat 
brownish, with four bristles. Pleurae shining, more brownish, in 
the middle below brown. The short hair of the mesonotum and 
the bristles are black. Abdomen wholly deep shining black, with 
short black hair ; ovipositor but little longer than the last 
abdominal segment, black. Legs deep brown, the knees and 
tarsi more yellowish ; middle tibiae with a stout spur ; front 
femora with some bristles below. Wings nearly hyaline ; the 
costal and subcostal cells, reaching back through the beginning of 
the submarginal cell to the fourth vein, a band beginning at the 
outer part of the first vein and reaching over the anterior cross- 
vein, an elongate spot of about the same width covering the pos- 
terior cross- vein, and the apex of the wing, save a rounded interval 
at the very tip, brown ; third and fourth veins somewhat con- 
vergent at the tip ; anal cell rounded distally, not at all drawn out 
into a point. Lengch 4§-5 mm. 

This species, it will be seen, does not agree in all its 
details with the characters given by Loew for the genus, 
but the discrepancies are trivial. In some specimens the 
brown spots of the wings are narrower, and that at the 
tip might be called an incomplete band. Four speci- 
mens.

Two specimens, which agree closely with the descrip- 
tion and figures of this species. With them, however, 
are others which seem less certainly identical. They are 
smaller, and have in the wings a ninth ray, as is de- 
scribed for U. pjohjclona. The latter, however, is described 
as having four scutellar bristles.

6. Trypeta {Plagiotoma) wco7npleta, n. sp. 

(J , $ . Yellow, the mesonotum with two, the abdomen with 
eight black spots. Front rather narrow, especially below ; on 
each side with three or four brownish bristles, and with two pro- 
clinate ocellar bristles. Antenna light-yellow ; arista bare, black 
on the distal half. Face vertical, the oral margin projecting a 
little. Proboscis short ; palpi projecting slightly in front of the 
oral margin. Mesonotum light ochraceous yellow, with short 
yellow hairs and brownish bristles ; just above and behind the root 
of the wing on each side, there is a small round black spot ; 
scutellum with four bristles. Abdomen a little more reddish, with 
yellow hairs ; on each side with fonr rounded black spots. Ovipo- 
sitor yellow, as long or a little longer than the last two abdominal 
segments (in one specimen it is drawn out longer than the 
abdomen). Legs yellow. Wings very similar to those of P. obliquay 
Say, except that the first oblique band back of the tip of the wing 
is represented only by the blackish spot at the tip of the fourth 
vein and a slight yellowish tinge in front of it. Length 
83-4 mm. 

This species is closely allied to P. ohliqua, Say, but 
differs in both sexes in the absence of the pleural spots 
(there is a blackish spot at the root of the halteres, and 
a small pair on the underside of the scutellum), and in 
the wing-markings.

Numerous speciuiens from St. Vincent and Chapada, 
Brazil. I have no North American specimens for com- 
parison, but the description applies so well that I think 
the identification is probable. The West Indian speci- 
mens are lighter yellow, and the thoracic stripes are 
darker and are continued on the scutellum. Those from

Brazil agree more closely with Loew's description. lu 
the West Indian specimens there is also a distinct 
frontal stripe, only slightly indicated in the South 
American ones.

Abdomen long ovate ; first three segments light-yellow ; the next 
three yellow with a narrow median stripe and an ill-defined spot, 
each side black. Legs light-yellow ; hind tibiaj with a stout pre- 
apical bristle. Wings elongate, deep brown in front, nearly 
hyaline on the posterior part ; in the outer part there are two or 
three small round hyaline spots, near which the brown is of a 
deeper colour. Length 3^-4 mm.

notum continued and uniting at the tip, leaving the middle as the 
continuation of the middle brown stripe. Pleurse for the most 
part shining black, somewhat thinly pruinose above. Abdomen 
shining black, thinly greyish-pollinose in an oblique light. Legs 
deep-brown, the femora more black, the base of the tibiae, the four

above the oral margin in front. Thorax light opaque yellow, the 
mesonotum with light-brown stripes, the median pair extending on 
the sides of the scutellum. Pleurae with two brown stripes, the 
one below the base of the wings, the other across the base of the 
middle coxae. Abdomen yellow or brownish-yellow, with three 
rows of small, dark-brown spots, forming three interrupted stripes ; 
the spots are sometimes obscure, perhaps as the result of desic- 
cation. Legs light-yellow, the four posterior tibias with a proximal 
narrow brown ring. "Wings clouded with dark-brown along the 
costa to the tip, on the cross-veins and on the base and outer part 
of the fourth vein ; penultimate section of the fourth vein not 
one-half the length of the ultimate section. Length 4-5 mm. 

This species has its markings, aside from those of the 
wings, very much as they are in 8. macula.

yellow. Wings hyaline, the penultimate section of the fourth 
vein about one-half the length of the ultimate section. Length 
5 mm. 

One specimen. St. Vincent. This species is allied to 
S. longijjennis, bnt is distinct in the more shining colour 
and in the distinctly narrower front, which is perceptibly 
longer than wide. Possibly it is identical with Laiiccania 
muscaria, Loew (Centur., i., 87; Schiner, Reise der 
Novara, Dipt., 282), but the face is not shining. As the 
shining black colour is the final difierence between Sapro- 
myza and LaiixcDua, this species would pi-operly come 
under the latter. The difference from S. longipennis is, 
howevei', very slight.

in drying, and fresh specimens are needed to determine 
the markings with clearness.

yellowish-grey, the narrow orbits grey. Autennte red, the upper 
border of the second and third joints brown or blackish. Face, 
cheeks, and occiput, for the greater part, densely grey-pollinose. 
Palpi light-yellow. Mesonotum densely brownish grey-pollinose, 
with numerous small rounded points where the bristles and hairs 
arise ; scutellum like the mesonotum. Pleurae and metanotum 
densely grey-pollinose ; a small brown spot on the upper part of 
the mesopleurse. Abdomen light coffee-brown ; the first segment 
and a narrow median stripe, and irregular spots on the sides of the 
other segments posteriorly opaque grey ; the median stripe is 
narrow and of equal width throughout. Femora black, with the 
tip yellow ; front tibife, except the base and immediate tip, and 
the front tarsi black ; middle and posterior tibiae and tarsi yellow, 
the tibise more or less brownish in the middle, the tarsi blackish at 
the tip. Wings nearly uniformly tinged with brownish-yellowish. 
Length 4 mm. 

Ten specimens. St. Vincent. A closely allied species 
in the writer's collection, from San Domingo, differs in 
the presence of distinct stripes on the mesonotum. In 
some specimens the irregular grey spots of the abdomen, 
nearly subdivide the brown into four series of spots or 
stripes.

costal vein of nearly the same length as the third, or slightly 
longer. Length 2 mm. 

One specimen. St. Vincent. " Near the sea by open 
stream." It is possible that this species were better 
located under Discocerina. The third joint of the

carinate, though the convexity of the upper part is con- 
fined to the middle part.

conical ; in the female more oval. Femora for the most part 
black ; tibise yellow with the middle portion more or less brown ; 
tarsi yellow, the distal joints brownish or brown. Wings cinereous 
hyaline ; second section of the costa less than twice the length of 
the third. Length Ih mm.

the tarsi, save the terminal joint, yellow. Wings cinereous 
hyaline; third section of the costa two-thirds the length of the 
second section. Length l|-2 mm. 

Five specimens. St. Vincent. This species is pecu- 
liar in the very large oral opening, resembling the forms 
placed in the vicinity of Ephydrci, from which, however, 
it is distinctly separated by the presence of a spinous 
bristle at the tip of the second antennal joint.

obscure the ground-colour save in an oblique light. Front black, 
but mostly concealed beneath fine yellow or brownish-yellow 
pubescence. Thorax black, shining through the thin brownish 
dust ; pleurje thinly greyish-dusted. Abdomen black, moderately 
shining ; oval, the fifth segment of the male much longer than the 
preceding one. Legs black, the tip of the tibise, the knees and the

cJ. Front opaque brown, the frontal lunule whitish. Antennoe 
black, the first two joints whitish above ; third joint orbicular. 
Face brown on the upper part, the lower portion, the cheeks and 
the posterior orbits silvery-grey ; the orbital space, bounded by 
the curved line, exceedingly narrow above, becoming broad below 
the eyes ; near this line on either side below there are two mode- 
rately strong bristles ; face in the middle strongly carinate, or sub- 
tuberculate ; clypeus projecting, of the colour of the lower part of 
the face. Mesouotum, scutellum, and upper part of the pleurte 
opaque dark- brown ; a narrow stripe just above the dorso-pleural 
suture, to the root of the wings, silvery-grey ; lower part of the 
pleura and the metanotum grey, all opaque. Abdomen broadly 
oval, the first and fifth segments concealed, the fourth long ; 
opaque silvery grey, the second segment more or less brownish- 
grey. Legs black ; all the tarsi, except the terminal joint, yellow. 
Wings whitish ; third section of the costa about half the length of 
the second section. Length Hmm. 

Five specimens. St. Vincent. Because of the narrow- 
ness of the first and fifth segments, the abdomen appears 
to be composed of but three segments, the chief charac- 
teristic of Trimerina. However, the same character 
appears in some of the species placed under Hecamede, 
and while the colorational differences from the known 
species of Trimerina are marked, they very closely

resemble those of H. lateralis, Loew, from Europe. I 
doubt not that the species belongs wherever H. lateralis 
does ; in fact, I am not quite sure that the species may 
not be identical, for the deeper colour of the present 
species seems to be the chief difference between them.

$ . Front composed almost wholly of the shining black verti- 
cal triangle, leaving only a narrow margin opaque black and 
silvery. Antennae black ; third joint light-yellow on the lower 
half, much longer than broad ; arista short pectinate. Face very 
narrow, gently convex from side to side, without grooves, receding 
below, in colour silver-white ; bristles of the sides below weak ; 
inferiorly the sides and the cheeks are shining black. Clypeus 
concealed. Eyes very sparsely pubescent. Thorax deep black ; 
mesonotum much shining ; scntellum opaque ; the pleural whitish 
dusted. Abdomen shining black ; fourth segment about as long 
as the two preceding together. Legs wholly light-yellow as are 
also the cox«. "Wings yellowish or brownish hyaline ; third 
section of the costal vein longer than the second ; penultimate 
section of the fourth vein very short, the posterior cross-vein 
remote from the border of the wing. Length 1 mm. 

One specimen. St. Vincent. Notwithstanding the 
pectination of the arista I locate this species under 
Hydrina, by reason of the comparative bareness of the 
eyes, the structure of the face, and the position of the 
posterior cross-vein. According to the canons of zoologi- 
cal nomenclature the genus Hydra and its family ter- 
mination Hydrinse do not conflict with the name Hydrina, 
and it should have priority over Philygria.

Fallen, Dipt. Suec, Geomyzid., 4, 1823. 

The present collection includes, as is seen, a very large 
number of species belonging to this genus. I have 
scrutinized them with the utmost care, and have given, I 
trust, descriptions which will enable them to be recog- 
nized again. I have been able to recognize but a single 
species previously described, though it is possible that 
there may be others which have been already named. 
The difficulty in the determination of the obscurer 
coloured species from remote localities, is, however, so 
great that only a direct comparison of specimens from dif- 
ferent habitats will settle the question of their identity. 
Two species are included in the list (Nos. 17 and 18) 
which may not properly belong to the genus, but which 
would in all probability be sought for here.

$ . Black in ground-colour, thickly pollinose. Front longer 
than broad, only a little broader above ; densely yellowish-grey 
pollinose, with four rows of bristles, the median ones not extend- 
ing quite as far as the orbital ones. Antenna) reddi.sh-yellow, 
the third joint rounded, the arista with but few rays on the upper 
side. Face greyish-pollinose, like the front, flat or with a slight 
carina above ; vibrissis present ; cheeks not broad. Thorax densely 
pollinose, the mesonotum and scutcllum j'ellowish-grey, the pleura; 
more grey ; apex of the scutellum reddish. Abdomen black, yel- 
lowish-grey dusted. Legs reddish-yellow. Wings nearly hyaline ; 
anterior cross-vein situated before the insertion of the first vein ; 
third section of the costal vein only a little shorter than the 
second section Halteres yellow. Length 2 mm. 

Two specimens. St. Vincent. In all probability the 
present species belongs among tlie Ephydridai, but tbe 
very flat face and the presence of vibrissas will lead one 
to search for the species in this genus. The presence of 
the additional row of frontal bristles, the few rays to the 
antennal arista, the small carina, and the partial absence 
of the anal cell are all characters out of accordance 
with those of this genus, as well as the general colouring 
of the species. 

19. DrosopMla limhata, n. sp. 

^ $ . Head, thorax and legs yellow or reddish-yellow, but 
little or not at all shining ; third joint of the antennte brownish ;

twice the length of the third section. Length 1^ mm. 

Twelve specimens. St. Vincent. In most of the 
specimens the narrow brown bands of tbe abdomen are 
visible, but in some the whole abdomen is brown. The 
penultimate section of the fourth vein is very nearly equal 
to one-half the length of the ultimate section. A sinf]^Ie 
female specimen agrees in other respects but has the 
third costal section about three-fourths the length of the 
second section and the penultimate section of the fourth 
vein not more than one-third the length of the ultimate 
section. 

21. Drosophila similis, n. sp. 

$ , $ . Very much like D. pallida, but is larger, and the^ 
third section of the costal vein is very short, not longer than the 
penultimate section of the fourth vein. The second and third 
veins are parallel through nearly their whole length, and the second 
vein is unusually long. In most of the specimens the abdomen is 
brown, but in some there are black or brown bands as in D. pallida. 
The colour is reddish-yellow, sometimes more purely yellow.

blackish. 

Length 2 mm. 

Five specimens. St. Vincent. I refer this species 
with some doubt to the present genus^ as it does not 
have the typical markings of Phortica. There is a com- 
plete posterior basal cell ; otherwise the species resemble 
those of Brosophila. The oral vibrissas are weak. 
The bristles of the front are strong and reach nearly 
to the oral margin ; there is no preapical bristle to the 
hind tibife.

species, while agreeing sufficiently well in the other 
characters with the genus Hippelafes, I have thought 
well to distinguish subgenerically from the other species

proboscis. Others of the previously described species 
evidently belong to the same subdivision.

A large series of specimens from St. Vincent agree 
with the description of this species so closely that there- 
can be no question of their identity. With them, how- 
ever, there is yet a larger number which show such 
discrepancies that their specific identity is somewhat 
doubtful. I give herewith a description of the variety 
or species, whichever it may be.

Two specimens. This species, the only one that has 
been recognized in the western continent, appears to 
resemble the European C. acidicornis. As in that species, 
the fourth vein terminates at the extreme tip of the wing, 
the distance between the two cross-veins is less than half 
of the length of the last section of the fifth vein. The 
wings are nearly hyaline.

Fourteen specimens. Sea level to 1500 feet. They are 
but little different from Phora interrupta, but average 
larger, less dark on abdomen, wings clearer, and first 
light vein less curved. Both species have the hind 
femora tipped with brown. 

4. Phora venata, n. sp. 

^. Head and abdomen black, thorax brownish-black, legs 
including tarsi yellow, femora a little darker. Palpi brown, 
antennae blackish. Legs destitute of setae, second heavy vein not 
forked. Anterior frontal bristles proclinate. Bristles of the front 
small, except the verticals. Halteres brown. Under surface of 
fore femora with a row of delicate curved hairs. Pleurse yellowish 
below. Hypopygium yellow, rather large, with two black pro- 
jecting claspers below and a brownish lamellar portion, bristly 
below, projecting backward ; also a slender yellow styliform organ 
(penis ?) in the centre below. Length TS mm. 

The most noticeable peculiarity of the species is the 
venation. The heavy veins reach beyond the middle. 
The so-called light veins are much heavier than in any 
other known North American species, comparatively 
straight, and have the appearance of making a complete 
union with the heavy veins, instead of stopping a little 
short and then running parallel with them. 

One male. 1000 feet. 

5. Phora furtiva, n. sp.

nate, tibiae destitute of large bristles on the outer side ; head, 
thorax and abdomen black, legs brownish, the tarsi and anterior 
tibiae yellow. Front black, the bristles rather below medium 
size, the fine hairs somewhat conspicuous, antennae blackish, more 
or less yellowish at base, palpi yellow. Thorax sub-shining, 
pleurse shining black, halteres black. Femora in fully coloured 
specimens dark brown, in less mature ones yellowish-brown, the 
tibise lighter. Hind tarsi almost twice the length of the tibia:-. 



Dlptera of St. Vincent {West Indies). 437 

Hind tibiae on the posterior edge with longer hairs, on the inner 
side of this a row of about twelve small bristles. Wings slightly 
yellow, heavy veins reaching but little past the middle, second 
vein reaching barely more than half-way from the humeral vein to 
the fork of the third, on the costa. First and second light veins 
ending about equally far from the apex, the cell before the first 
as wide as the narrowest part of the one behind it. Length 
I'o mm. 

Two females. 1000 feet. 



6. Phora divaricata, n. sp. 

^ , 5 . Antennaj, palpi, pleuraj, halteres and legs deep yellow, 
anterior frontal seta3 reclinate and divaricate ; second heavy vein 
forked, the first attaining three-fourtlis of the distance from the 
humeral to the second, the first light vein moderately arcuated, the 
fourth scarcely visible, very blender. Front dark brown or black, the 
lower edge yellowish ; thorax above varying from yellow to black, 
frequently yellow with indistinct darker markings longitudinally. 
Abdomen black or brown, the posterior margin of each segment 
with a narrow band of light-yellow, which continues more or less 
as a stripe down the middle of the dorsal surface. Venter yellow. 
Anterior tibiae on the front side with a row of four setae, middle 
tibiae with two together a trifle below the knee, hind tibiae with a 
minute row of fine hairs down the posterior edge, but no setae 
except at apex. Hind femora considerably thickened. Wings 
tinged with yellow, costa reaching a little past the middle, with 
two rows of fine setae, which are more divaricate at the base. The 
two branches of the second vein are very close together, j-et 
distinct. In the males the genitalia are bent up under the venter, 
giving the abdomen a knobbed appearance. Length 1-4 to 
1'8 mm.

the apex ; legs wholly yellow, the tarsi scarcely darker, middle and 
hind tibiae with a row of nearly a dozen small bristles running 



488 Professor J. M. Aldrich on the 

down the posterior edge ; hind femora moderately thickened, with 
a few little bristles below near the tip ; abdomen bright reddish- 
orange in colour, toward the tip and below irregularly blackened. 
In one specimen, a male, the reddish colour is confined to the base, 
and there is a well-defined black spot on each side of the middle of 
the dorsum. Wings quite deeply tinged with yellow, the heavy 
veins reaching far beyond the middle, the first light vein but little 
curved, ending at or but little before the apex. The first heavy 
vein ends just perceptibly past the middle of the distance between 
the humeral vein and the tip of the branch of the second vein. 
The fourth light vein is distinct to the border. Length 1'3 
to 1'7 mm. 

Two males, seven females. 500 to 1500 feet. 



8. PJiora viagnipalpis, n. sp. 
$ . Second vein forked, anterior frontal bristles procliuate, legs 
yellow, the hitid femora a little brownish, head, antennae, thorax, 
and abdomen black ; palpi, halteres and pleural brownish-black. 
The palpi in the male are enlarged, divaricate, destitute of the 
usual strong set^. Wings hyaline, the light veins very slender, tip 
of second vein just midway between the humeral and the fork of 
the second, on the costa ; second light vein with a greater 
curvature than usual, almost parallel with the vein befoie it. 
ending but little behind the apex. The heavy veins reach but 
little beyond the middle of the wing. Length 1-2 to 1-4 mm. 

Four males. Sea level to 1000 feet. May. 

I have also four females, same size and locality, which 
differ in having a lighter but variable coloration. The 
halteres and palpi vary from yellow to brown ; dorsum of 
thorax brown. The wings are as in the preceding males. 
I regard them as the same species, although there is 
not usually such a range of variation, especially between 
the two sexes. 

In addition to the species described above, the collec- 
tion contained two specimens of somewhat different 
coloration from any described species, and different from 
each other, which, on account of the absence of any 
striking characters, I leave undetermined for the present.

2. Hemerodromia, sp. 

$ , Head black, thickly grey poUinose. Eyes narrowly separated 
in the middle of the face. Antennae and proboscis light yellow. 
Thorax reddish yellow, the mesonotum somewhat greyish pollinose, 
and with feeble indications of longitudinal stripes. Legs light 
yellow ; front femora greatly thickened, and with a distinct emar- 
ginatiou for the reception of the tip of the tibiae. Wings as in 
H. defessa. 

One specimen. In the absence of specimens for com- 
parison, it is hazardous to say that this is the same as 
H. oratorio, Fall., but I can find no important differences 
from Loew's description. I suspect that H. empiformis, 
Say, may also be the same species (Coquillett has wrongly 
identified it). Coquillett makes no mention of the con- 
tiguity of the eye in his H. rogaforis, and leaves it to be 
inferred that the bristles of the thorax are microscopic. 
If such be the case, the two species are distinct. 

For those species of Hemerodromia, in the sense of 
Loew, in which the neuration is normal, Coquillett has 
recently resuscitated the table name Mantipeza, Rondani, 
referring all the others to Hemerodromia, with the excep- 
tion of H. scapidaris, Loew, for which he creates the 
genus Neoplasia. Hemerodromia precatoria, Fall. {H. 
tnonostigma, Meigen), is a true Mantipeza, in Coquillett's 
sense, but he leaves it in Hemerodromia, so that it is difficult 
to say just what his conception of Mantipeza really is. 
In the examination of the descriptions and specimens of 
most of the known species of Hemerodromia, in the sense 
of Ijoew, I find the following different combinations of 
characters : — 

1. Anal cell present, discal and second posterior cells 
also present. — Mantipeza of Coquillett. 

This is Hemerodromia of Bigot, and it should be con- 
sidered that of Meigen also. 

2. Anal cell present, second basal cell present, discal 
cell wanting'. — 3Iantir>eza of Bio-ot. 

This includes H. nigriventris, H. defecta, etc. Mr. 
Coquillett also includes in this group H. alhipes, Walker. 
Mr. Coquillett's acumen in the detection of so many of 
Walker's defectively described species is to be commended. 
In the present case, however, has he some special infor- 
mation concerning the type of H. alhipes ? Mr. Walker 



Diptera of St. Vincent {West Indies), 441 

located albipes with precatorta, in which there is a " dis- 
coidal areolet/' and which should, therefore, belong in 
Coquillett's Mantipeza. He also describes the body as 
being " fulvo-canis " in colour, with a " slight tawny 
tinge," while Coquillett calls the '* thorax and abdomen 
black." If Mr. Coquillett has information concerning the 
type, then Walker^s description should be cancelled in 
toto, and the species rest upon Coquillett's diagnosis. 

3. Anal cell present, second basal and discal cells 
united ; second posterior cell sessile. — Neoplasta of 
Coquillett. 

4. Anal cell wanting ; second basal cell present and 
elongated; discal cell wanting. — Microdromia of 
Bigot. 

This includes the species described above, and a num- 
ber of others. 

If Thomson is correct in his reference of H. analis, 
then there is yet another group, differing from Neoplasia 
in the second posterior cell being complete.

2. Anthomyza xanthopoda, n. sp. 

J, $. Front narrower than in A. cinerea, narrowest below; 
red, the vertical margin brownish ; on either side the vertical 
margin is white, and bears the outer row of short bristles. 
Antennae yellow ; arista bare. Face and cheeks light-yellow, 
the latter scarcely more than one-third as wide as the vertical 
diameter of the eyes. Thorax black in ground-colour, thickly 
ashy-grey pollinose, with a shade of yellowish on the mesonotum ; 
hair of the mesonotum bristle-like. Abdomen black, greyish 
pruinose, opaque ; rather slender in the male, the hypopygium pro- 
tuberant ; all the segments with a narrow yellowish or whitish hind 
border ; hair short, wholly black. Legs yellow ; last joint of all

able from A. cinerea by the narrower front and cheeks, 
the less densely pollinose thorax, black hair of the 
abdomen, &c. 



In addition to the foregoing species listed or described 
from the island of St. Vincent, there are, among the 
specimens submitted to me, about twenty others, the 
systematic positions of which are yet more or less 
doubtful. Several of them will probably require the 
erection of new genera for their reception. The descrip- 
tions will be given in a later paper, in connection with the 
report upon the Grenada Diptera now in my hands for 
study. 

The present collection of Diptera is the first one of any 
extent that has been studied from the West Indian Islands. 
Isolated species, or small collections, chiefly of the larger 
forms, have been studied by various authors, but no col- 
lection has ever represented nearly so fully the microfauna 
as does the present one. The West Indian Diptera-fauna 
is essentially a common one, with a strong South American 
facies. Very few of the species, I believe, will be found 
restricted to any single island or group of islands. But 
comparatively few of the species will be found to occur in 
North America, and they for the most part are either 
species of wide-spread habitats, or else are confined to

446 Professor Williston on the Diptera of St. Vincent. 

the southernmost portions of the United States, especially 
Florida, whose fauna seems to partake largely of the 
southern type. 

It may, perhaps, occasion some surprise that so large a 
proportion of the foregoing species are determined as new. 
This is due to two facts. First, the larger portion of 
the species of the collection are small or very small, the 
majority not exceeding four millimetres in length and 
nearly a half requiring the use of a compound microscope 
for their study. Second, the small, obscure species 
are exceedingly difficult to recognize from the majority of 
the existing descriptions of South American forms. I can- 
not hope to have avoided all synonyms. That some of the 
species have been previously described from South and 
Central America will be a matter of comparative indiffer- 
ence if I have succeeded in so describing and figuring the 
present ones that the future observer of specimens from 
these regions will be able to determine them with tolerable 
certainty. 

My thanks are due to Professor Aldrich for so kindly 
undertaking the study of the families Dolichopodidse and 
Phoridee, to which he has given so much attention in 
recent years.
