PREFACE. 



THIS short volume is the first issued of a series that is 
intended to give a systematic account of the Coleopterous 
Fauna of British India. 

The present work on the Longicorn Beetles of India was 
undertaken some years ago by Mr. C. J. Gahan, whose unique 
knowledge of the group is well known. From a variety of 
causes, but chiefly want of leisure, the Author has been 
unable until now to complete a sufficient portion of the MS. 
to allow of the publication of even an instalment. This 
issue, therefore, is only Part I. of the contemplated volume, 
and deals solely with the forms arranged under the family 
Cerambycidae, which according to the latest classification 
includes the Prionidze. A considerable portion of Part II., 
which will give an account of the Lamiidse, is already in 
manuscript ; it is therefore confidently expected that the 
completion of the whole work will not be unduly delayed. 

Other volumes on the Coleoptera of India are in active 
preparation, arid it is intended to include a General Intro- 
duction to the Order with one of these volumes. In the

meantime, to allow the reader to follow the technical terms 
used in the descriptions of these insects, diagrammatic illus- 
trations of the parts of beetles belonging to the group here 
dealt with, and explanations thereof, are subjoined below. 

I may add that Vol. II. of the Butterflies, the MS. of 
which is nearly completed, will follow this present volume.

Order COLEOPTERA. 

Suborder POLYP HAG A. 
Superfamily LONGICORNIA. 

Family CERAMBYCID^. 

Head obliquely inclined in front, sometimes subvertical, but 
with the genal edge always oblique or vertical, formed into 
a more or less distinct and often projecting angle behind 
the base of the mandible; clypeo-frontal sutures generally 
distinct, the clypeus as a rule relatively large. Last joint of 
palpi not pointed at the end. Front tibiae not grooved under- 
neath, the middle tibiae, except in Disteniinw, never notched 
nor grooved on the outer margin. Tarsal claws always simple ; 
in the great majority of forms, widely divergent or divaricate. 

This family, although comprising fewer specific forms than the 
Lamiidce, is less homogeneous in character and probably contains 
as great a number of different genera. It appears to be on the 
whole the less specialised of the two, including as it does a much 
larger proportion of forms which have retained what may be 
regarded as primitive characters. But as these characters appear, 
some in one genus or group, some in another and never all together, 
the problem of determining the phylogenetic relationship of the 
various groups is one of the greatest difficulty, and the classification 
of the family remains for the present to a great extent artificial. 
The minor groups in which Lacordaire arranged the genera appear 
to me to be, with few exceptions, natural ones ; and in dealing 
with the larger subfamilies I have, with certain modifications, 
adopted them here, but have not adhered to his sequence in the 
arrangement of the groups. The family, so far as it is represented 
in the present fauna, I have divided into four subfamilies, three 
of which correspond to the three main groups into which Gangl- 
bauer has divided the European Cerambydnce; the fourth subfamily 
is equivalent to Lacordaire's group Disteniides with the addition of 
two genera which he had placed elsewhere. The division is based 
to some extent on larval characters, which however are not given 
in the following synopsis. 

VOL. i. n 



2 CEEAilBYCID^. 

Synopsis of Subfamilies. 

A. Inner lobe of maxillae obsolete or very small ; 

gula without mentigerous process ; profchorax 
margiuate at sides ; front coxae strongly 
transverse Prionince. 

B. Inner lobe of maxillae more or less well 

developed; prothorax not marginate at sides ; 
front coxse rarely strongly transverse. 

a. Head more or less elongated and either 

gradually or abruptly narrowed behind 
eyes ; gula with a mentigerous process, 
which, as a rule, is very distinct ; mandibles 
frequently provided with a ligamentous 
fringe and molar tooth at base; wing- 
vein Cu. 1 usually bifurcate behind and 
joined near middle to Cu. 2. 
a'. Head very short in front ; antennae 
close to the base of the mandibles ; 
front coxae subglobular, with their aeeta- 
bula rounded, or exceptionally slightly 

augulated on outer side Disteniince. 

b'. Head longer in front ; antennae less 
close to base of the mandibles ; front 
coxae conical and prominent, with 
their acetabula more or less strongly 
angulated on outer side Lepturince. 

b. Head variable in form, but seldom distinctly 

narrowed behind eyes ; gula with or 
without a mentigerous process, this, when 
present, usually very short ; mandibles 
never provided with a ligamentous fringe 
or molar tooth at base; wing-venation 
generally reduced by disappearance either 
of Cu. 2 or branch of Cu. 1 or of both, 
sometimes as complete as in Lepturince, 
but only in forms which have no distinct 
mentigerous process to the gula Cemmbycina?,.

Inner lobe of maxillae obsolete or very small ; ligula corneous ; 
mentum not covering base of maxillae ; gula without distinct 
mentigerous process. Antennae usually inserted close to the base 
of the mandibles. Prothorax, except in a few species, margiuate 
at the sides. Mesonotum, except in the single genus Philus, 



without stridulatory area. Front coxae strongly transverse, with 
their acetabula widely open behind. AVing-venation conforming 
generally to the type represented in fig. 6 Intro., in which vein A 1 
has a rather large subelliptical cell in its course, and vein Cu. 1 is 
simple and not united with Cu. 2 ; exceptionally however (group 
Philini) vein Cu. 1 gives off one or two branches and is united 
by a cross-vein with Cu. 2. 

From the subfamily as above defined two groups, sometimes 
placed in it, will have to be excluded. These groups the Paran- 
drides and Anoplodermides may be regarded as distinct sub- 
families, but as they are not represented in the Indian fauna it is 
unnecessary to characterise them here. The character by which 
the Prionince may be in practice most readily recognized is the 
possession by the prothorax of sharp lateral margins. These 
margins are usually distinguishable along the whole length of each 
side, running at a greater or less distance from the outer angles 
of the coxal cavities and from the prosternal sutures ; they are 
sometimes entire but more frequently dentate or spinose, the 
spines or teeth sometimes large and few in number, sometimes 
small and forming a series ; exceptionally the margins curve down- 
wards from the base so as to run very close to the acetabula and 
prosternal sutures ; in certain forms become obsolete or wholly 
disappear on the anterior half of each side ; they are completely 
wanting in one species only among those dealt with in the present 
fauna. 

This subfamily is represented in nearly all parts of the 
world, and includes many of the largest species of Coleoptera. In 
certain of the groups the eyes are finely facetted, and this character- 
is frequently associated with the possession of metallic or other 
bright colours. So far as at present known, no species belon<r- 
ine; to any of these groups occurs within our faunistic limits. 
In the Indian genera the eyes are always coarsely facetted, and 
the species, with one or two exceptions, are restricted in their 
range of coloration between black and those lighter shades of 
In-own which verge on red and yellow. 

Following the example set by Lacordaire in dealing with large 
subfamilies, I propose here to give first a synopsis of the different 
groups of genera, to be followed later by a synopsis of the 
different genera associated together in each group. 

Synopsis of Groups. 

A. Episterna of metathorax parallel-sided for the 
greater part of their length or nearly so ; broadly 
truncate behind. 

a. Prothorax with from one to four strong marginal 
teeth or spines on each side ; prosternum not 
flat and horizontal behind.

tinctly emarginate ; ligula bilobed or emar 
ginate ; antennae of cJ longer than half body.

so, or else provided each with a series of several 
teeth or spines.

only one small submediau tooth ; first antennal 

joint short Group Eurypodini. 

b'. Lateral margins of prothorax crenulate or

moderately long Group Macrotomini. 

B. Episterna of metathorax with posteriorly converging 
sides, narrowly truncate or obtusely pointed at 
apex. 

a. Third joint of tarsi cleft almost to base ; vein

base of mandibles Group JEyosomini. 

b'. Head vertical in front ; antennae more or less 

distant from base of mandibles .... Group Monodesmini. 

b. Third joint of tarsi cleft to middle only; vein 

Cu. 1 of hind wings branched, united by "a cross- 
vein with vein Cu. 2 Group Philini. 



Group PRIONINI. 

The genera of this group are distinguished by having usually 
three teeth or spines on each side of the prothorax, the number 
being increased to four in one genus and reduced to one in another ; 
the intercoxal process of the prosternum more or less strongly 
curved and sometimes subvertical behind, never in the form of 
a thin flat plate. The clypeus often more or less coriaceous 
in front ; the labrum always distinct, sometimes narrow and 
more or less rectangular in form, sometimes semicircular and 
transverse, but never triangular. The antennae variable in form, 
but with the first joint one-third at least longer than broad. 
The epimera of the metathorax prolonged behind so as to pass 
alongside the outer end of the coxae. The legs sometimes 
asperate or scabrous, but never spinose. The paronychium 
small, but usually visible between the claws and in most of the 
genera setose at the end. 

Except in one genus (Logceus) there is no strongly-marked 
sexual difference in the puncturation of the thorax, the sexes 
differ chiefly in the length of the antennae and in the length 
and form of the mandibles.

Group ACANTHOPHORINI. 

This group was formed by Lacordaire for three very closely 
related genera, only one of which is included in the present fauna, 
the other two are restricted in their range to the African region. 
Lameere regards all three as constituting but a single genus, which 
he places in the group Prionini. From the genera of that group, 
Acanihophorus differs as follows : The first joint of the antennae 
relatively very short and thick, the labrum triangular and the 



ACAXTHOPHORU6. 23 

mandibles projecting forwards almost horizontally in both sexes. 
The clypeus not coriaceous in front, but the suture between it 
and the labrum distinct. The legs are smooth, and the third 
tarsal joint is completely bilobed. The wing-venation in Acantho- 
pliorus resembles that of Dori/stJienes and most Prionince, but in 
Tithoes, its African representative, there is a cross-vein uniting 
vein Cu. 2 with Cu. 1.

Group CANTHAEOCNEMINI. 

Eyes feebly emarginate or almost entire. Antennae short, 
sometimes (genus Cantharocnemis) extending but little or not at 
all beyond the base of the prothorax. Lateral margins of pro- 
thorax distinct, with a projecting angle or tooth between the 
middle and the base. Tibise rather strongly dilated at the end, 
with the outer angle prominent or dentiform ; the outer edges 
dentate ; the terminal spurs broad and flat. Wing-venation of 
the usual Prionine type. 

There is a difference of opinion in regard to the affinities of 
this group. Lacordaire, attaching undue importance to the 
unusual form of the tibiae, placed it among his groups of aberrant 
Prionides and not in the normal series. Lameere, on the other 
hand, associates the Cantharocnemini with the Spondylini, con- 
sidering the affinities between the two to be very close. With 
this view I am unable to agree. In the Spondylini the prothorax 
is not marginate at the sides, and the wing-venation is that of the 
less specialised Cerambycince and most Lepturincf. The Spondylini 



26 CERAMBYCIIXE. 

are undoubtedly, as M. Lameere maintains, a primitive group, but 
have not, in my opinion, any direct or close relationship with the 
Oaniliarocmmini. The latter I consider to be somewhat second- 
arily modified forms of true Prionince, and as such I place them 
here. The group is almost entirely confined to the African region, 
the only species known to occur outside Africa being a very rare

Cant\i&rocnQrnis,Serville,Ann. Soc.Ent. Fr. i, p. 132 (1832) : Lucord. 
Gen. CoUopt. viii, p. 32 (1869). 

Type, G. spondyloides, Serv., an African species. 

Range. Bombay, Ceylon and Africa. 

In form rather short and robust. Head broad, with the front 
very short and obliquely sloped, the clypeus transversely depressed, 
the eyes transverse, scarcely emarginate in front; mandibles 
strong, sometimes falciform and emarginate at the apex in 
the male. Antennae robust, variable in length, but generally 
much shorter than the body in both sexes, 11-jointed ; first joint 
thick, rather short, slightly curved, thickened towards the end ; 
joints third to tenth subequal, angulate at the apex, eleventh 
longer than the tenth. Prothorax transverse, its lateral edges 
project in an angle at a greater or less distance from the base 
and converge thence more or less gradually towards the apex. 
Elytra rather short, convex, rounded at the apex, broader in front 
than the base of the prothorax. Legs stout, somewhat compressed ; 
femora a little broader in the middle ; tibiae enlarged at the distal 
end, with very prominent dentiform outer angle, especially in the 
anterior two pairs, the external margin of each armed with a 
variable number of teeth ; tarsi moderately long, with the first 
joint rather narrow, glabrous underneath at the base and along 
the middle, third bilobed but with the lobes very short in some 
of the species. Intercoxal part of prosternum strongly arched 
in front, sloped posteriorly with its end resting in a depression of 
the mesosternum ; mesosternal process narrow. 

This genus of Prioninat may be readily distinguished from all 
others occurring in the Indian region by the exceptional form of 
the tibiae, which, with their prominent dentiform outer angle and 
toothed external border, somewhat resemble those of the Lucanidce. 
Apart, however, from this character and the tendency to a great 
abbreviation of the antennae, the genus conforms with the normal 
Prionid type and there appears to be no good reason for 
regarding it as a particularly aberrant member of the family.

Reddish brown, varying to a somewhat darker tint. Head 
sparingly punctured on the vertex, closely and rugosely on the 



clypeus, sides and the lower part of the anteunal supports; vertex 
marked with an impressed line which widens out into a channel 
in front between the eyes and antennal supports ; clypeus limited 
above by two oblique or somewhat arcuate lines that converge 
towards the channel between the depressed transversely directed 
anteunal supports ; mandibles of male falciform, with tooth at 
base and an emargination forming two teeth at the apex, the 
upper border carinate, those of the 
female very much shorter, straight 
or but slightly diverging from the 
base and incurved towards the tip, 
the inner edge of each with one or 
two feeble teeth. Antennae of $ 
scarcely reach beyond the base of 
the prothorax ; those of the J are 
longer and stronger ; joints third 
to tenth angulated in front at the 
apex, more acutely so in the d 
than in the , rather sparingly 
punctured behind, closely and 
rugosely punctured in front. Pro- 
thorax transverse, the lateral edges 
projecting in an angle at about 
one-third of their length from 
the base ; disk convex with a 
slight depression in the middle, 
sparingly punctured and glossy 
over the whole of the middle area, closely rugose-punctate towards 
the sides. Elytra much less than twice as long as their width 
across the base, obtusely rounded at the apex, irregularly rugose 
and punctate in the $ , smoother and less punctate in the <5 , 
each with two feebly-raised dorsal lines. Tibiae of the anterior two 
pairs rather sparingly punctured in front, closely behind, those of 
the hind pair densely and coarsely punctured on both sides ; third 
joint of tar^i completely bilobed. Hind breast sparsely clothed 
with longish tawny hairs ; abdomen finely and rather closely 
punctate ; last ventral segment of $ rounded behind and fringed 
with tawny setae.

28 CEBAHBYCIDJE. 

This group, which, under another name, is Lacorclaire's group 
Zarucides, includes only two genera Eurypoda and Neoprion ; the 
latter is regarded by M. Laraeere as merely a subgenus. One 
species only occurs within our faunistic area, the others are found 
iu China, Japan, Malay Peninsula, Sumatra and Borneo. The 
group has no close relationship with any of the other groups 
included in our fauna.

present near the apex of the third. Pronoturn of the <S as broad 
as the elytra, with its sides nearly parallel from the slightly pro- 
jecting front angles up to the lateral angles placed a little behind 
the middle, thence converging obliquely to the base ; the front 
margin somewhat bowed backwards in the middle:; the base 
rounded in the middle, sinuate towards the sides ; disk feebly 
convex, with a large, sparsely punctate, smooth area, roughly 
octagonal in shape, over the whole of the central part, the spaces 
between this and the lateral edges are very finely and closely 
punctate and opaque ; pronotum of $ with its sides somewhat 
convergent in front from the prominent lateral angles, strongly 
punctured near the sides. Elytra somewhat flattened above, 
broadly rounded at the apex, the sides narrow, nearly vertical, 
with an obtuse costa running between each and the disk. Epi- 
sterna of metathorax nearly parallel-sided, narrowed a little near 
the apex, which is straightly truncate. Legs rather short ; femora 
flattened fusiform ; the hind pair extended but little beyond the 
second abdominal segment ; tarsi relatively short, with the first 
joint scarcely longer than the second.

the sides of the pronotum, very glossy ; antennae blackish, 
sparsely and rather finely punctate. Head 
sparsely punctured, the punctures becoming 
closer and rougher behind the eyes. Pro-

Group MAGROTOMINI. 

Eyes entire, or but feebly sinuate in front. Ligula entire. 
Prothorax crenulate, denticulate, or spinulose along each side. 
First antennal joint long, or moderately long, never very short. 
Intercoxal process of prosternum more or less flat and hori- 
zontal. Legs more or less spiny. A sexual difference in the 
puncturation of the thorax generally present and often very 
strongly marked. 

In this group I include two of Lacordaire's groups the Rem- 
phanides and Macrotomides ; the first is distinguished as follows : 
The third antennal joint not longer than the first, the prothoracic 
lateral margins distant from the prosternal sutures and the epi- 
pleures of the elytra strongly widened out near the base ; in 
the true Macrotomides the third antennal joint is always longer, 
generally very much longer, than the first, the prothoracic margins 
are not very distant from the prosternal sutures and the elytral 
epipleures are little widened near the base.

prosternal sutures. Each edge armed with a series of short spines 
or teeth. Elytra much more than twice as long as their width 
across the base, rounded at the apex, usually dentate at the 
suture. Legs rather long, more or less spinose beneath ; tarsi 
long, with the first joint narrow and much longer than the second.

Greatly resembles M. crenatus (Fab.) and agrees with it in most 
points of structure, especially in the proportions of the first joint 
of the antennae and front tarsus, but it is distinguishable from 
that species : (1) by the greater relative length of the third joint 
of the antennas, as this joint in the male is quite as long as the 
fourth, fifth, and sixth united ; (2) by the smaller size of the

shining spaces on the male pronotum, the two anterior of which 
are somewhat ovate in shape and slightly elevated (except at the 
inner edge) instead of being depressed ; (3) by its darker colour 
that is almost black with the elytra dark brown.

(S . Dark brown in colour ; the elytra rusty brown towards 
the base and somewhat yellowish towards the apex ; the antennae 
at the apex, the hind legs and all the tarsi somewhat reddish. 
Head coarsely punctured between the eyes, closely and finely 
granulate behind. Antennae reach to the apical third of the 
elytra ; first joint twice as long as it is broad, closely and coarsely 
punctured ; third more than twice as long as the first and equal 
in length to the fourth, fifth and two-thirds of the sixth united, 
spinose beneath and along the front margin, the spines rather 
short. Pronotum about one-fifth broader at the base than at the 
apex, very closely and finely punctate and opaque, but with two 
triangular spaces before the middle, a small rugose spot external 
to each of these, a narrow transverse band near the base, a median 
streak from the middle and an oblique rugose band from each end 
of the basal band, all more or less strongly nitid. Elytra rugulose- 
punctate and very finely granulose, the granules become more 
distinct and the surface rougher towards the base, especially on 
the slightly elevated part near the scutellum. Front femora and 
tibiae asperate, beset with short sharp spines beneath ; middle 
and hind femora sparsely punctulate, armed with a few spines 
beneath. First joint of the front tarsus longer than the second 
and third united.

d". Head as in Macrotoma, but the eyes larger and more 
closely approximated above. Antennae as long as the body, 11- 
jointed ; third joint thickened, asperate, more than twice as' long 
as the first, canaliculate above and below. Pronotum with denti- 
culate lateral edges that converge gradually from base to apex ; its

hind angles acute and directed slightly backwards, somewhat in 
the manner characteristic of the Elatendce ; its upper surface finely 
and very closely punctured and opaque, but with two rather small, 
coarsely punctured, glossy depressions in front of the middle and 
a short band of a similar kind running obliquely forwards from 
the base on each side. Prosternum, inesosternum and sides of 
the metasternum very closely punctulate ; a very sharply limited, 
rather strongly depressed median triangular area of the meta- 
sternum, sparsely punctulate and glossy. Last ventral segment 
sinuate or subtruncate at the apex. Other characters almost as in 
Macrotoma, but with the front legs, especially the tibiae, more 
elongated. 

5 . Antennae shorter and more slender, with the third joint 
scarcely asperate. Pronotum coarsely punctured except in the 
middle ; its hind angles project rather strongly outwards, but 
not backwards. Sterna less closely punctured ; metasternum 
without a definite space in the middle. 

This genus is not recognized by M. Lameere, who regards the 
two species here included in it as forming a small group in 
the genus Macrotoma, with characters that differ only in degree 
from those met with in the species of our second section of that 
genus.

pubescence, which covers the whole of the elytra with the excep- 
tion of the costae ; the latter character especially serves to 
distinguish the species from ^32. sidcipenne, White, with which it 
agrees very closely in structure.

shorter pubescence; the inner dorsal costa of each elytron prolonged 
farther back, its apex less rounded and armed with a longer 
spine.

Group MONODESMINI. 

Front of the head vertical or subvertical ; the antennae in- 
serted at some distance from the base of the mandibles, thus 
giving room for the lower lobes of the eyes, which are usually 
very large, to reach anteriorly up to or almost up to the front. 




AN<EME. 53 

Lateral margins of prothorax in general feebly developed, some- 
times (Anceme) consisting merely of a fine carina that extends on 
each side from the basal margin to the outer angle of the coxal 
cavity. Wing-venation of the usual Prionine type. 

This group, as here defined, is a provisional one and corre- 
sponds in part only to Lacordaire's group of the same name. For 
two of the genera included by him, I have formed a separate 
group the Philini. Two other genera Cyrtoiiops and Crinosoma, 
which were imperfectly known to him and doubtfully placed in 
the group will also have to be excluded; one belongs to the 
Disteniince and the other to the Cerambycince. Anceme, the only 
genus of the group included in our fauna, is represented by two 
species in Africa and one, recently discovered by Mr. H. L. 
Andrewes, in the Nilgiri Hills, Southern India. M. Lameere 
(Faune Ent. de 1'Afrique Trop., Longicornes, p. 47, 1903) has 
associated this genus with Plectogaster, Waterh., placing both 
in the group Anacolini. The Monodesmini have, it is true, 
a fairly close relationship with the Anacolini, as they have also 
with the ^Egosomini ; they ought therefore perhaps to be merged 
in one or other of these two groups. With Plectogaster, however, 
the case is different. Notwithstanding the fact that this genus 
has been placed in the Prionince not only by M. Lameere but also 
by two other experienced entomologists, I am decidedly of opinion 
that it ought not to be so placed, but was rightly referred by 
its author to the Cerambycince, chiefly for these reasons : (1) the 
prothorax has no true lateral margin, (2) the front coxae though 
transverse are not more so than in many Cerambycince, (3) the 
inner lobe of the maxillae is quite fully developed, (4) the meso- 
notum has a large undivided stridulatory area and (5) the wing- 
venation resembles that of no true Prionince. What M. Lameere 
describes as a lateral margin, consists of a sharp ridge or carina 
that extends down the side of the prothorax close to, and almost 
parallel with, its hind margin, approaching more closely in fact to 
the hind margin at its lower end than at its upper. Such a ridge, 
though less feebly developed, is not uncommon in the Cerambycince, 
and is to be found co-existing with the true lateral margin in some 
Prionince,

rounded in the middle at each side, furnished with a feeble lateral 
carina curved downwards from the base to the outer angle of the

tudinal carina along the middle. Legs subequal, laterally com- 
pressed ; hind femora much shorter than the abdomen ; first joint 
of hind tarsi shorter than the next two united, claw-joint long. 
Front coxae prominent, strongly transverse, almost contiguous ; 
the intercoxal part of the prosternum very narrow ; middle

Entirely of a testaceous or fulvous-red colour, the elytra, 
especially towards the apex, the legs and the body beneath of 
a somewhat paler tint. Head punctured 
sparsely in front, closely and subrugosely 
on the top and at the sides ; mandibles 
almost vertically inclined; lower lobes of 
the eyes very large, extended forwards 
between the antennae and the base of 
the mandibles, the gense in consequence 
reduced each to a narrow oblique strip. 
Prothorax shorter and narrower than the 
head, closely and rather finely punctured, 
impressed with a sinuate groove just 
behind the raised front margin, a feeble 
transverse groove close to the base, and a 
broader groove or channel along the middle. 
Elytra strongly and rather closely punc- 
tured, sparsely setose above and somewhat 
thickly setose at the apical margin ; each 
with a sharp dorsal carina which stops 
short a little before the base in front and at about an equal dis- 
tance from the apex behind. Dorsal edge of tibiae very narrow 
a,nd somewhat carinate.

narrowed towards the occiput, subvertically inclined in front ; 
labrum distinct, joined by a transverse suture to the clypeus ; 
gula without mentigerous process ; eyes large, emarginate.

first joint very short, the third about twice as long as the first and 
subequal in length to the fourth. Prothorax rather small, its 
lateral margins feebly developed and sometimes partly or wholly 
obsolete ; when present they curve downwards from the basal 
margin and extend forwards to a greater or less extent, but always 
at some distance from the outer angles of the coxal cavities. 
Mesonotum with or without a stridulatory area, this when present 
is divided by a median line or groove. Front coxae prominent, 
strongly transverse ; the intercoxal process attaining to a level 
with the coxse and not prolonged behind them, its posterior face 
vertical and very narrow. Tarsi rather long, with the third joint 
cleft to the middle only ; paronychium of claw-joint setose. 
Wings with vein Cu 1 joined by a cross vein to Cu 2 with one or 
two branches behind. 

Owing to the richness of their wing-venation, the two genera 
included in this group occupy a somewhat exceptional position 
among the Prionince and appear to be primitive in relation to the 
other members of the subfamily. Their wing-venation greatly 
resembles that of Oxymirus (Intro, fig. 5) and other genera of 
Lepturince. In some other respects also the Philini show an 
affinity with the latter subfamily. They are closely related to 
Mantitheus, Fairm., a genus that inhabits Northern China, and are 
related also, but less closelv, to the Mediterranean genus Vesperus, 
Latr., which some authors class with the Lepturince.

covered with a faint greyish-tawny pubescence. Antennae with 
the third to eighth joints rather strongly angulate at the apex on 
the anterior side. Prothorax with its lateral margins extended 
from the base not quite up to the middle of each side ; pronotum

Group Disteniides, Lacord. Gen. Coleopt. ix, p. 225 (1869). 
Tribe Disteniini, Leconte $ Horn, Classif. Col. N. Amer. p. 307 
(1883). 

Head elongated, more or less gradually narrowed behind the 
eyes ; the latter transverse, feebly emarginate or entire ; front 
vertical and very short, almost limited to the transversely raised 
antennal supports ; clypeus oblique ; mandibles with truncate or 
scalpriform apical edge ; gula produced anteriorly between the 
bases of the maxillae so that it forms a distinct mentigerous 
process ; ligula corneous. . Antennae inserted before the eyes, close 
to the base of: the mandibles. Front coxae large, globular, their 
acetabula usually open behind and, except in Cyrtonops, not 
angulate on the outer side, the epimera having coalesced with the 
prosternum to form a suture. Acetabula of middle coxae closed 
or, exceptionally, open on the outer side. Episterna of rnetathorax 
very narrow, gradually attenuated behind. Middle tibiae most 
frequently with an oblique notch on the lower part of the outer 
border. Wing-venation of the Lepturine type, always without a 
cell in the course of vein A 1. 

The Disteniina?, though placed by Lacordaire as a group among 
the Cerambycides, were given a prominent position in his arrange- 
ment of that subfamily, in which also he included the Lepturince. 
Leconte & Horn (Classif. Col. N. America), while retaining them 
also in the Cerambydnce as one of their Lepturoid tribes, have 
suggested that they are a primitive group, a suggestion arising 
from a consideration of the structure of Distenia, one of the most 
specialised of the genera in the group. The relationship between 
the Disteniince and the Lepturince is, no doubt, a close one, but the 
differences between them are at the same time so strong that I 
find a difficulty in placing them both in the same subfamily, and 
therefore treat the Disteniince as a subfamily in themselves. The 
genera are few in number, and, with the exception of Cyrtonops 
and Dynamotteg, are all very closely related.

impressed with a distinct median groove that extends from the 
clypeus to the occiput. Prothorax closely rugosely punctate, but 
with a small, smooth, feebly raised tubercle 
a little in front of the middle of the base. 
Elytra very strongly punctured, the punctures 
in more or less regular rows along the disc, 
somewhat irregularly placed on the sides, the 
interstices sparsely covered with minute seti- 
gerous punctures ; each with one or two distinct 
costse, the inner costa, when present, lying 
between the second and third rows of punctures, 
the outer one between the fourth and fifth 
rows. Hind femora very much thicker than 
the others and strongly toothed along each

Type, D. audax, Pasc. 

Range. Sikhim and Manipur. 

cJ. Head elongated behind the eyes and gradually narrowed 
backwards, but becoming parallel- sided, thus forming a sort of 
neck near the occiput ; eyes transverse, smaller and less prominent 
than in Cyrtonops ; mandibles with a truncate but rather short 
edge at the apex, each with an inner tooth between the middle 
and base ; maxillary palpi normal, longer than the labial ; sub- 
mentum short but distinct. Antennae inserted very close to the 
base of the mandibles, extended to the middle of the elytra, 
sparsely pubescent ; first joint not more than half as long as the 
head, slightly curved, gradually thickened towards the apex; 
third joint nodose at the apex, shorter than the fourth ; fourth 
to eleventh subcanaliculate beneath. Prothorax subcylindrical, 
longer than broad, slightly rounded at the sides. Mesonotum 
with stridulatory area divided by a median impressed line. 
Elytra strongly punctured in longitudinal rows. Femora strongly 
thickened, the hind pair much longer and thicker than the others; 
tibiae sharply angulate at the apex on the outer side, the middle 
pair with a sinus, thickly beset with setae on the outer margin 
below the middle, the hind pair deeply notched on the inner 
side close to the apex. Prosternum moderately broad between 
the coxae, dilated behind to meet the epimera, the acetabula, which 
are rounded on the outer side, are thus completely closed behind. 
Mesothoracic epimera shut off from the acetabula by a lateral 
prolongation of the metasternum. Episterna of inetathorax very 
narrow, acuminate behind. 

This remarkable genus, of which only a single species is known, 
constituted one of Lacordaire's tribes of " Aberrant Cerambycides." 
But, like Cyrtonops, it falls naturally enough into the Disteniince 
and in some respects agrees even better than Cyrtonops with the 
general characters of that subfamily.

elytra ; first joint stout, strongly punctured and sparsely ciliate ; 
third snorter than the fourth, slightly 
nodose at the apex ; fourth to tenth sub- 
equal in length, eleventh longer than the 
tenth ; each joint from the fifth or sixth 
with a feeble longitudinal channel in front 
and another behind near the lower border. 
Prothorax with a broad dark channel or 
depression along the middle bearing four 
or five longitudinal ridges ; the sides red- 
dish, strongly rugose-punctate, furnished 
like the head with some longish setae. 
Elytra sparsely setose, each with two 
dorsal carinse and one lateral, also about 
eight rows of strong punctures, some of 
the rows long, some short, the intervals 
Pasc between them slightly raised; none of 
the rows or carinas extend to the apex ; 
apical part closely and very finely punctulate. Apex of femora 
and base of tibiae blackish ; femora with large sparse punctures, 
the hind pair asperate beneath. 

This is a very rare species, of which I have seen only three 
examples, two in the collection of M. Eene Oberthiir and one in 
the collection of Mr. Fry. In the smaller specimen, from Kurseong 
in Sikhim, the antennae extend to the middle of the elytra, while 
in the larger one, ticketed ' ' India " and probably the type, they 
do not extend beyond the anterior third of the elytra. The 
difference is probably sexual.

Body and legs black, the elytra dark metallic green, rather 
denselv covered with a short greyish-tawny pubescence. Head 
densely and very finely punctulate, marked on the vertex with a 
median impressed line which extends 
forwards to the clypeus, the latter

Type, T. callichromoides, Thorns. 

Range. Assam, Malay Peninsula, Java, and Borneo. 

The species of this genus have a characteristic metallic-blue or 
green colour, but differ only very slightly in structure from those 
of Distenia. The prothorax is one-third longer than broad, and 
is transversely striated near the base and apex and to a less degree 
near the sides ; the femora are longer, more slender and cylin- 
drical than in Distenia, the hind pair of the male reaching a little 
beyond the apex of the elytra in most of the species. 

60. Typodryas callichromoides, Thorns. Syst. Ceramb. p. 227 (1864). 

Of a metallic-green or blue colour, the elytra with a sutural 
band of a different tint usually violaceous or blue. Head 
transversely rugulose above behind the eyes, impressed on the 
vertex with a median line. Antennae 
twice as long as the body in the 
male, less than twice as long in the 
female, the long hairs with which 
they are furnished beneath some- 
times to be seen freely projecting, 
especially in the female. Prothorax 
rather strongly constricted and broadly 
grooved near the apex, marked with 
a sinuate groove near the base, 
finely striated transversely in front of 
the anterior groove and behind the 
posterior groove, the disc slightly 
depressed in the middle, feebly raised 
and transversely wrinkled towards the 
sides. Elytra cut away obliquely at 
the apex, each being more prolonged 
and rather strongly spined at the 
outer angle and feebly dentate at the 
suture ; each has two raised dorsal 
lines not extending to the apex, the 

outer line more distinct, marked with two rows of strong closely 
placed punctures between the two lines, two rows between 
the inner line and the suture and another row external to the 
outer line ; the side in its anterior half is densely and less

regularly punctured ; the rows of punctures of unequal length, 
some extending a little beyond the middle of the elytra, others 
not reaching to the middle. The hind femora extend a little past 
the apex of the elytra in the male, but do not quite reach to the 
apex in the female. Apex of last ventral segment subtruucate in 
the male, rounded in the female.

Hob. Assam : Sylhet and Sudiya. 

61. Typodryas trochanterius, sp. n. 

Metallic green, subnitid, with a steel-blue sutural band on the 
elytra ; legs and base of antennae dark blue, the rest of the 
antennae of a darker violaceous tint. Closely resembling T. calli- 
chromoides, Thorns., in colour, this species is smaller in size ; with 
the elytra less oblique at the apex, the sutural tooth more distinct 
and the dorsal lines more faintly raised ; the prothorax less deeply 
constricted and grooved near the apex, the disc very faintly 
depressed in the middle and less strongly wrinkled towards the 
sides so that the median area is not distinctly marked off from 
the lateral parts ; the hind femora shorter, not reaching quite to 
the apex of the elytra in the male ; this sex differs also from the 
same sex of callichromoides in the trochanters of the front legs, 
which are each armed with a short spine at the apex. The female 
is without these spines and has the last ventral segment rounded 
at the apex instead of subtruncate ; the sexual difference in the 
length of the antennae and hind legs is very slight.

Black, for the most part dull, furnished sparsely with longish 
suberect setae ; femora yellowish white at the base. Head 
above, prothorax and first antennal joint minutely and very 
closely punctured, the punctures on the median part of the 
pronotum run together in a longitudinal direction and impart 
to it a slightly rugose appearance. Elytra with strong somewhat 
transversely elongated punctures arranged in four rows on each, 
extending from the base to the apical sixth part, the punctures 
of the innermost row less strong than those of the other three 
rows ; the lines between the rows slightly raised ; apical sixth 
part and the interstices between the large punctures of the 
anterior five-sixths very minutely and closely punctulate, covered 
with a very faint blackish-brown pubescence. Legs, except at the 
base, black, subnitid, sparsely setose. Antennae ( $ ?) nearly twice

Subfamily III. LEPTURIN^E. 

Head either gradually or abruptly narrowed posteriorly, with a 
more or less distinct neck ; gula produced between the bases of 
the maxillae forms a meutigerous process, which is, as a general 
rule, very distinct and exceptionally only very short ; ligula mem- 
branous or coriaceous, usually bilobed or emarginate. Antennae 
inserted before or between the eyes, generally at some distance 
from them, sometimes contiguous to their lower lobes. Prothorax 
not marginate at the sides. Mesonotum usually with a stridulatory 
area, which is sometimes absent, but when present it is in most 
cases divided by a smooth median line or groove. Front coxae 
prominent, usually somewhat conical in form, always laterally 
produced, with their acetabula more or less strongly angulated on 
the outer side. Acetabula of middle coxae widely open to the 
epimera. Episterna of metathorax as a rule rather broad in front, 
gradually narrowed posteriorly. First ventral segment of the 
abdomen little or not at all longer than the second. Wing- 
venation variable; sometimes of the type represented in fig. 5 
(Intro.), more often a modification of that type in which the cell 
has disappeared from the first anal vein. 

The Lepturince can be with little difficulty distinguished from 
both the Prionince and Disteniince, but the differences between the 
Lepturince and the Cerambycince are less strongly marked, at least 
in the imago ; in certain doubtful cases it is not easy to decide 
to which of the two a genus should be referred. One of the chief 
reasons for regarding the Lepturince as a subfamily distinct from 
the Cerambycince is to be found in the structure of their larvae. 
In these the pleurae or side-pieces of the head are dehiscent 
behind the epistoma (or clypeus) and angulated at the end, 
whereas in the larvae of Cerambycince they meet together up to 
the apex and are separately rounded behind. In the Lepturine 
larvae also, the head is less invaginated in the prothorax and the 
legs are more slender and not so short as they are in the larvae of 
other Longicornes. Unfortunately however, as the larvae of only 
a relatively small number of the different forms are known, these 
structural characters can seldom be resorted to in order to decide 
upon the affinities of a genus.

the derm, rather densely covered with yellowish grey or fawn- 
qoloured pubescence. Antennae of c? 
about one-fourth longer than the body ; 
joints from the third compressed ; sixth to 
tenth acutangulate anteriorly at the apex, 
fifth rectangulate, fourth obtuse ; second 
and third scarcely as long as the first, dis- 
tinctly shorter than the fourth ; fifth nearly 
as long as the third and fourth united. 
Prothorax with a sharp, slightly upturned 
tubercle on each side and five feeble 
obtuse tubercles on the disc two before 
the middle and three near the base ; 
finely punctulate, with a few sparse 
granules at the sides behind the lateral 
tubercles. Elytra somewhat sparsely 
punctate from the base to the apical third. 
Third joint of tarsi cleft to the middle, its 
lobes a little wider than in other species of 
the genus. 

The female is shorter and broader than the male and less 
pubescent ; the antennae extend very little beyond the middle of 
the elytra, with the fourth joint scarcely longer than the third, and 
the fifth but little longer than the fourth ; the elytra do not com- 
pletely cover the abdomen, but leave the greater part of the pygidium

succeeding joints narrow and subcylindrical, not serrate at apex 
third slightly longer than the first or fourth and shorter than 
the fifth. Prothorax transverse, a little widened just before the 
middle, armed there on each side with a sharp spine. Stridulatory 
area on mesonotum with a shallow groove or depression along 
the middle. Elytra broad, rather short, rounded at the apex, 
completelv covering the abdomen posteriorly. Front coxae some- 
what transverse ; their acetabula strongly angulate on the outer 
side and closed posteriorly. Legs similar in length and form to 
those of ApatopTiysis ; third tarsal joint cleft beyond the middle. 
Intercoxal process of abdomen narrow, somewhat sharp in front. 
Wing-venation differs from that of Oxymirus by the absence of a 
cell from vein A 1. 

This genus is closely related to ApatopJiysis, Ohev. ; it differs 
chiefly in the form and length of the antennae and the relative 
proportions of the first four or five joints, also in the more complete 
venation of its wings. The type species has a great resemblance 
in form to some of the Pno&UM!, and at first sight might be 
mistaken for a species of that subfamily. 

67. Peithona prionoides, sp. n. 

Black ; bare of pubescence and dull above, very sparsely 
pubescent and somewhat nitid on th& 
underside. Head strongly and very thickly 
punctured, except at the apex of the clypeus, 
along the channel between the antennal 
supports and over a slightly depressed area 
on the vertex, the last of these sparsely 
punctured, the other two impunctate. An- 
tennae subnitid ; fifth joint at the apex and 
the succeeding joints for the greater part of 
their length finely carinate in front, with 
an elongated poriferous pit on each side of 
the carina. Prothorax transverse ; strongly 
arid very thickly punctured over the middle 
of the disc, less thickly towards the sides, 
almost impunctate around the lateral spines. 
Scutellum broad, rounded behind, finely and

base. Elytra rather strongly punctured, the 
punctures separated by distinct intervals ; 
each with two smooth dorsal lines. Epi- 
sterna and lateral borders of metasternum strongly but not thickly 
punctured ; the rest of the metasternum finely and very sparsely 
punctate ; the abdomen almost as finely but less sparsely punctate ; 
the punctures both on the thorax and abdomen carry each a short 
pale hair. First joint of hind tarsus as long as the second and 
third united.

c?. Head strongly, but somewhat gradually narrowed behind 
the eyes, with the posterior part forming a distinct neck ; eyes 
large, prominent, coarsely facetted, with a narrow and feeble 
emargination in front. Antennae inserted on the front at some 
distance from the eyes, longer than the body; first joint long, 
curved, thickened at the apex ; third shorter than the first, and 
scarcely longer than the fourth, fifth longer than the third ; sixth 
to tenth gradually shorter; eleventh scarcely longer than the 
tenth. Prothorax much narrower in front than afc the base, 
furnished with a sharp conical tubercle at the middle of each 
side and four tubercles on the disc two, smaller, in front of the

the prothorax, narrowed slightly backwards, each truncate at the 
apex. Legs moderately long; femora fusiform-clavate, the hind 
pair reaching to the apex of the elytra ; tibial spurs short ; first 
joint of hind tarsus as long as the next two united. Acetabula 
of front coxae closed in posteriorly by the prolongation of the 
epimera and thus meet the intercoxal process of the prosternum. 

From Capnolymma this genus differs as follows : the fore part 
of the head much shorter, the antennae inserted farther apart, 
the prothorax tuberculate on the disc, the elytra less narrowed 
posteriorly, and the first joint of the hind tarsi not longer than 
the next two united.

prothorax, on the apical fourth of the elytra, on the tips of the 
femora and of the first antennal joint, also on the sides of the breast 
and on some spots on the abdomen ; elsewhere it is of a greyish tint 
slightly mixed with tawny, with here and there some small brown 
spots. Head with the clypeus and neck almost bare of pubescence 
and somewhat rugosely punctate, the vertex between the eyes 
furnished with two small tubercles. Prothorax somewhat con- 
stricted a little behind the apex, its front margin raised. Elytra 
strongly and closely punctured on the anterior three-fourths ; not 
visibly punctured on the apical fourth, the white pubescence there 
being much denser than the mixed pubescence in front ; apices

so to the apex, where each is truncate. Legs moderately long ; 
femora sublinear, the hind pair much shorter than the abdomen ; 
tibial spurs short ; first joint of hind tarsus as long as the 
second and third united; third joint deeply cleft, the claw- 
joint long, the claws not very widely divergent. Front cox* 
moderately exserted, angulate outwards, their acetabula closed 
posteriorly by the approximation of the epimera to the slightly 
dilated hind end of the rather narrow intercoxal process. Wings

71. Caraphia minor, sp. n. 

Very like C. cribraia, but smaller and relatively somewhat 
narrower, with the antennae longer, those of the female extending 
by about the last two joints past the apex of the elytra, and 
with the fifth and sixth joints longer in proportion to the fourth ; 
the channels along the joints scarcely distinguishable except on 
the last four or five ; the punctures of the elytra form definite 
longitudinal rows, except near the suture and along the lower 
part of each side, the punctures of alternate rows oblong, 
carrying each a short, curved, pale tawny seta, the others more 
quadrate, not setigerous ; the dorso-lateral depression on each 
elytron very faint ; the wings without cell in the course of the 
first anal vein. 

The male of this species, if I am right in considering as such 
the smaller of the only two specimens I have seen, differs but 
little from the female the antennae are a little longer, extending 
by nearly three joints past the apex of the elytra ; the last 
ventral segment is not shorter than the penultimate, whereas in 
the male, as well as in the female of C. cribrata, it is appreciably 
shorter.

which I have seen, the femora are yellow with the upper borders 
black. The author of the species has, however, described it as 
testaceous, with the antennae, legs, and elytral spines black, so 
that a certain amount of variation in colour must be allowed 
for. Although referred, but with some doubt, to Capnolymma, 
Pasc., by its author, this species certainly cannot be placed in that 
genus, the structure of the antennae and their point of insertion 
on the head being quite different, and the head itself not nearly 
so prolonged in front. It is in some respects more nearly related 
to the Holarctic genus Gaurotes, Lee.

Head variable in form, but seldom distinctly narrowed behind 
the eyes ; mandibles without membranous fringe on inner side ; 
maxillae bilobed : mentigerous process of gula often wanting, 
generally very short when present ; ligula usually membranous, 
sometimes corneous. Antennae inserted as a rule very close to 
the eyes at some distance from base of mandibles, exceptionally, 
close to the latter. Prothorax not marginate at sides. Mesonotum 
generally provided with stridulatory area, which rarely is divided 
by a median line. Middle tibiae never notched on outer border. 
Wing-venation reduced, usually by absence of vein Cu. 2. 

As already pointed out, the structural differences in the imago 
between the beetles of this subfamily and the Lepturince are not 
always well-marked, and in cases where the larvae are unknown 
there will be a difficulty at times in determining to which subfamily 
a species belongs. The wing-venation is, as a general rule, much 
more reduced than in the Lepturince : the second cubital vein is in 
the majority of forms absent; when present, it has usually lost all 
connexion with the first anal vein, appearing then either as an 
isolated vein or as a branch of the second cubital ; the first anal 
vein, except in one or two genera, has no cell in its course. This 
subfamily is by far the largest in the present family, and is well 
represented in most parts of the world. It offers a considerable 
amount of variety in the structure, form and coloration of the 
numerous species. In many of the groups the eyes are finely 
facetted, and where such is the case the habits of the insects are 
probably diurnal. In these groups the colours are generally 
brighter and the markings more varied than they are in those 
with coarsely facetted eyes. Several genera of this subfamily are 
characterized by the presence of small pits or pores placed close 
to the suture between the metasternum and its episterna, not 
far from its posterior apex. These pores, judging from what is 



91 

known of their function in the case of a few species, are con- 
sidered to be the external apertures of scent-glands. But nothing 
is known as to the nature of the scent in the great majority 
of the species. In a few, such as the European species Aromict 
moschata, the scent is like that of attar-of-roses.

Group PROTAXINI. 

Head short, rather broad, not narrowed posteriorly ; antennce 
inserted wide apart and as close to base of mandibles as in the 
majority of Prionime ; eyes at a short distance behind antennae, 
emarginate, rather finely facetted ; gula with distinct ineutigerous 
process. Antenna* shorter than body in both sexes. Prothorax 
rounded at sides, broader in front than at base, almost flat above, 
lateral edges somewhat sharp but not rnarginate. Mesonotum 
with undivided stridulatory area. Tibise carinate along each side, 
spread out at apex. Front coxae transverse, somewhat prominent, 
their acetabula open posteriorly. Acetabulaof middle coxae extended

This group is formed for the reception of a single remarkable 
genus which cannot well be included in any of the groups estab- 
lished by Lacordaire. In some points of structure, this genus 
shows an affinity with the Lepturince, but in the shape of the head 
and prothorax it resembles no member of that subfamily. From 
the forward position of the antennae, it appears to be a primitive 
form, although in certain other respects it is more specialized 
than the genera included in the next group.

tured, the punctures to a great extent 
hidden under a covering of short fulvous

This species enters into Sharp's genus CepJialallus, and possibly 
may not be really distinct from C. oberthuri, Sharp, the type of that 
genus, as it apparently differs only in colour, as the latter is 
described as piceous with the elytra ferruginous. Cephalallus, 
Ceplialocrius and Megasemum are distinguishable by such slight 
structural characters that I consider them at most as only sub- 
genera of Criocephalus.

The difference in colour that marks the female specimen here 
described is probably not altogether sexual, but due in part to 
individual variation. In the male specimens seen, there is an 
evident tendency to variation in the extent of the darker brown

Type, H. sericeus, Fab., a species found in Southern Europe and 
North Africa. 

Range. Mediterranean Subregion ; Tenasserim ? ; and West 
Africa. 

Head feebly raised, slightly concave between the antenna?, the 
antennal supports not prominent, front subvertical ; gula with 
a very short, broad mentigerous process. Antenna? longer to a 
greater or less extent than the body in the tf , shorter than the 
body in the $ ; first joint gradually thickened to the apex, the 
others subcylindrical or slightly compressed, eleventh slightly 
longer than the tenth in the d Prothorax slightly transverse, 
convex above, rounded at the sides and narrowed more towards 
the base than in front. Elytra either parallel-sided or nearly so for 
four-fifths of their length, rounded at the apex. Legs moderately 
long ; the femora gradually thickened from the base for two-thirds 
or three-fourths of their length, the hind pair not reaching to the 
apex of the elytra ; first joint of the hind tarsi not longer than 
the next two united. Intercoxal process of prosternum slightly 
arched, sloping gradually posteriorly, usually a little widened 
towards the end. 

. The species of this genus are in general form very like those of 
Stromatium, and are distinguishable from them by the less pro- 
minent antennal supports and the form of the intercoxal process 
of the prosternum. In the males the prothorax is usually larger 
and more convex than in the females, but it never has the large

Stromatium. 

Many of the species placed under this genus in the Catalogue 
of Gemminger and Harold do not really belong to it ; others are 
still unknown to me. The exact range of the genus is uncertain ; 
that which I have given above is based upon the distribution of 
such species as are known to me.

it may possibly prove, when the male is known, to belong to the 
genus Stromatium.

Varies from testaceous to dark brown in colour, rather densely 
covered with greyish-tawny pubescence. Antennae nearly twice 
as long as the body in the d" , a little longer than the body in 
the 5 ; first joint closely punctulate, canaliculate anteriorly near 
the base in the d 1 . Prothorax strongly and densely punctate, 
the punctures more or less hidden by the pubescence; dilated 
and somewhat rounded at the sides in the male, its width across 
the middle equal to that of the elytra and marked with a 
large, densely tomentose depression on each side ; more sharply 
rounded at the sides in the female ; the disc with four very feeble 
obtuse tubercles and a submedian callosity. Elytra rounded at 
the apex, armed each with a sutural spine ; the surface rather 
densely punctured, the punctures more or less covered over by 
the pubescence, marked also with numerous large conspicuous 
punctures with raised front edges each with a tawny seta. 

This is a widely distributed species, and the variation in size is 
pretty considerable. In some males the prothorax is relatively 
not so wide as in larger males ; it is possible that S. laticolle, 
Pasc., founded upon a large male from Batchian Island, is only 
a form in which the prothorax has reached its maximum of 
development.

Group CERAMBYCINI. 

The head usually has in front a central area limited by impressed 
lines or grooves ; gula with short mentigerous process ; ligula 
membranous. Antennae longer as a rule than body in d 1 , with 
third, fourth and sometimes fifth joints more or less thickened 
at apex, fourth shorter than the third or fifth. Acetabula of front 
coxse generally rounded, sometimes angulate, on outer side, closed 
or very nearly closed posteriorly ; the intercoxal process more or 
less strongly dilated at the end. Acetabula of middle coxae open to 
epimera. Metasternum without scent-pores. First sternite of abdo- 
men distinctly longer than the second. Wing-venation reduced, 
apparently by disappearance of posterior branch of Cu 1 and of 
connecting-vein between Cu 2 and A 1. 

The genera of this group are exceedingly variable in structure, 
and do not admit of being characterized with any great amount of 
precision. The characters given in the synopsis which follows, 
though applying to the great majority of the species in each 
genus, may possibly be found not to apply to all.

This species, wrongly identified as P. pedestris, White, is noticed 
in 'Indian Museum Notes ' (vol. i, no. 2, p. 91) as being injurious 
to Sal (Shorea robust a) and Jingham (Odina wodier), and is, no doubt, 
as stated in the ' Notes,' the insect referred to in the following 
extract from Mr. E. Thompson's ' Report on Insects injurious to 
Woods and Forests ' (1867) p. 415 : 

" A third Monochamus beetle was found under circumstances of 
extraordinary development. The pupae were discovered in solid 
cocoons, made of a substance resembling lime. The shell was 
fully the sixteenth of an inch in thickness, quite hard and firm, 
offering in fact more resistance to the pressure of the fingers 
than would a pigeon's egg. They were discovered beneath the

bark, imbedded between it and the wood, in a felled tree of the 
Butea frondosa or Dhak. The larvae had apparently only lived on 
the sap-wood, and underwent the second metamorphosis on the 
site of their original operations ; another remarkable fact was 
that these beetles are in the perfect state as early as March." 
In a footnote he adds : " I have since obtained numerous speci- 
mens of these beetles and their cocoons; imbedded to a depth of 
eight inches in logs of Odina wodier and Bombax heptaphyllum. 
They are the commonest and earliest variety of Monochami out, 
the perfect insects haviug been obtained as early in the season as 
November." 

Cocoons of Ploccedervs obesus from the Shan States, given to 
the British Museum by Mr. Gates, answer perfectly to the 
above description. They are egg-like, and consist almost entirely 
of calcium carbonate, dissolving readily in acids and leaving no 
residue. African species of the genus form similar cocoons ; so 
that probably all the species are alike in this respect.

Ferruginous-brown, with the elytra of a dark-brown colour 
along the outer borders ; clothed above with a faint greyish 
pubescence. Prothorax armed with a short and rather blunt 
spine on each side ; strongly but somewhat irregularly wrinkled 
above. Elytra finely and closely punctured, the punctures on the 
basal part unite and form a fine rugosity, those near the apex 
are sparser and more minute ; the truncate apices with a spine 
at each angle. 

This species is very closely allied to P. Jiumeralis, White, and 
apart from colour, differs from it only in being somewhat more 
sparsely punctulate towards the apex of the elytra, also the latter 
are more distinctly quadri-spinose.

characters : Prothorax somewhat angulate at the middle of each 
side in both sexes ; the upper surface more completely wrinkled, 
the subcentral space inclosed between the two longitudinal impres- 
sions almost as strongly wrinkled as the rest of the surface, and 
this space also completely divided by a median groove. The

shallower groove, bounded on each side by a slight carina, extends 
thence between the antennal tubers ; gular area with three 
strong transverse ridges. Antennas of the male longer than the 
body by from one-fifth to one- third of their length according to

those of the male, the first joint sparsely punctured, the third and 
succeeding joints somewhat flattened above, but not roughened at 

the edges. Prothorax a little 
longer than broad ; the disc 
with a slightly raised oblong 
space in the middle, the rest 
of the surface rather strongly 
transversely wrinkled but

minute and very dense, others 
larger and less densely 
spread. The claw-bearing 
joint of the tarsi long and 
the paronychium nearly

135. Derolus discicollis, sp. n. 

Allied to D. mauritanicus, Buq., which it closely resembles in 
size, form, and coloration, but is readily distinguishable from it 
by the presence of a large, smooth, somewhat rounded area that 
occupies almost the whole disc of theprotborax. On each side of this 
distinctly limited space, the prothorax is uneven and rather densely 
covered with pale grey pubescence, a few short hairs of the same 
colour being scattered over the discal smooth area ; near the base 
the prothorax is without striae but is crossed by two grooves, the 
anterior one sinuate, the other directly transverse, both extended 
at each side into the deep oblique lateral groove, which is as 
broad posteriorly, and as sharply edged as in D. mauritanicus, but 
gets narrower as it reaches the middle of the side, where it joins a 
smooth depressed area lying just in front of the middle. Each 
elytron ^s rounded externally at the apex and armed with a short 
spine at the suture.

138. Margites modicus, sp. n. 

Dark brown, the head and prothorax nearly black, the antennae 
and legs reddish brown ; faintly covered with short grey pubes- 
cence. Head densely and rather finely punctured ; without 
impressed line above. Antennae almost as long as the body in 
the $, and about one-fourth longer in the.c?; third and fourth 
joints rather strongly thickened towards the apex in the J, 
slightly thickened in the $ . Prothorax evenly rounded at the 
sides, narrowed and feebly marked with transverse grooves at the 
base and apex ; the whole of the dorsal surface almost bare of 
pubescence, and covered thickly with short irregular ridges, that

silky pubescence of a uniform greyish or yellowish-grey colour. 
Head impressed with a short 
median groove above between the 
eyes. Prothorax strongly corru- 
gate above, most of the ridges 
intricately convoluted, a few only

Eyes rather closely approximated above, reaching nearly to a 
line with the antennal condyles in front. Antennae of tf shorter 
than the body in most species, a little longer in some ; h'rst joint 
rather short, not reaching to front margin of prothorax; third

less sharply angulate at the apex. Prothorax rugose, rounded at 
the sides, constricted and transversely grooved near base and apex. 
Elytra more or less parallel-sided, obliquely truncate or subtruncate 
at the apex and armed or not with teeth or spines. Acetabula of 
front coxae feebly or not at all angulate on the outer side, closed 
posteriorly ; intercoxal process raised and rather narrow in the 
middle, gradually sloped and expanded towards the end. Legs 
moderately long; the hind femora hardly extended past the third 
abdominal segment in the d 1 and the second in the $ ; first joint 
of hind tarsus shorter than the next two united. 

In most species of this genus, including all the Indian ones, the 
pubescence on the elytra is somewhat characteristic in its colour 
and distribution : it is partly tawny, partly grey, sparser on some 
parts and condensed on others, with a tendency to form more or 
less regular longitudinal or transverse series of linear, oblong or 
quadrate spots.

prothorax rather densely covered with tawny pubescence ; elytra 
with a mixed pubescence, partly tawny and partly ashy-grey in 
colour, denser on some parts, sparser 
on others ; the grey pubescence forms 
series of ill-defined oblong or quadrate 
spots on the disc, and is more irregul: rly 
diffused on the sides. Head with a 
slightly raised median carina on the 
vertex. Antennae robust, extended 
very little past the middle of the 
elytra ; first joint not reaching past 
the hind border of the eye ; third and

and irregularly rugose ; each side with an irregular tubercle close 
to the front margin, the disc with two just before the middle; 
the tops of the ridges and tubercles glabrous and nitid. Elytra 
rounded externally at the apex; each subsinuate near the suture 
armed at the suture with a distinct spine ; the apical margin 
obscured by a fringe of tawny hairs. Body beneath and legs 
covered with pubescence of a prevailing yellowish-white tint, but 
more or less distinctly tawny in places. Hind femora not extend- 
ing past the hind border of the second abdominal segment.

grooved near base and apex. Elytra parallel-sided, narrowed 
near the apex ; each with a posterior subrnarginal cariua, with 
the apex truncate and more or less distinctly bidentate. Pro- 
sternum raised between the coxae, sharply deflexed posteriorly, 
and dilated at the end so as to almost meet the epiniera. 
Acetabula of front coxae not angulated outwards. Legs mode- 
rately long ; femora carinate on each side near their lower portions ; 
first joint of hind tarsus shorter than the next two united. 

The most distinctive of these characters is the presence of a 
submarginal carina on the posterior part of each elytron. The 
three species included in the present fauna are all characterized 
by the presence of a very strongly and closely punctured dark 
brown lateral area that extends from the base to a greater or less 
extent past the middle of each elytron. 

I. Elytra with glabrous dark brown streaks posteriorly.

Coleopt., Atlas, pi. 85, fig-. 1 (not a good figure). 

Dark brown ; with a yellowish-white pubescence that covers 
the head, the sides of the prothorax, and a considerable part of 
the elytra ; the latter each with a large, glabrous, very strongly 
punctured dark brown area at the side that extends from the base 
to the posterior third and spreads more than halfway across the 
elytron near the middle of its length, there are also four or five 
longitudinal glabrous streaks between this area and the apex and 
a few also near the base ; antenna?, legs, and underside covered 
with greyish or tawny-grey pubescence. The antennae extend 
past the apex of the elytra by about their last joint in the $ ' and 
their last two in the d 1 ; third joint very slightly longer than the 
first and about one-third longer than the fourth ; fifth to tenth 
strongly and sharply angulate or subdentate at the apex on the 
anterior side, eleventh a little longer than the tenth, shortly 
appendiculate. Prothorax rounded, rugose and pubescent at 
the sides ; glabrous above, furnished with a variable number of 
sharp longitudinal costae. (In the type from Singapore there are 
about ten costse, four of which are straight and very sharply 
defined, the others placed more towards the sides, slightly curved 
and somewhat irregular; in two specimens from Mergui there 
are only two longitudinal costae, the disc of the prothorax be- 
tween them and the sides irregularly and somewhat intricately 
rugose.) Elytra very strongly punctured, with the punctures 
larger and very closely placed on the large dark brown areas at 
the sides and also near the base, smaller and less dense on the 
glabrous streaks near the apex ; the submarginal carina of each 
elytron near the apex very distinct ; the apex of each rather 
strongly bidentate.

of grey pubescence. Prothorax strongly and irregularly rugose, 
scantily clothed with patches of tawny pubescence, unevenly 
rounded at the sides, marked near the apex with one and at the

distinguishable from that species 
by the four or more straight, 
sharp longitudinal ridges on the 
disc of the prothorax and a

Hob. Southern India : Cauara (T. R. D. Bell). 

In general structure and puncturation this species agrees fairly 
well with N. torrida, Pasc., but has the prothorax somewhat more 
strongly tuberculate at the sides. The difference in the form of 
the intercoxal process of the abdomen is probably sexual and not 
specific. When writing my original description of this species, I 
was not acquainted with Pascoe's species except by description, 
and consequently gave a wrong impression in regard to its affinities.

structure of the antennae and legs ; also, like that genus, it has 
the acetabula of the middle coxae shut off from the epimera by a

differs as follows : Antennal supports separated by a moderately 
broad channel, so as not to form an almost continuous ridge 
between the antennae. Prothorax distinctly longer than broad, 
the sides scarcely rounded and not at all tuberculate, the disc 
rugose-punctate. Elytra somewhat depressed along the middle,

* Although Perroud has described the prothorax as "deux fois et detnie 
aussi long que large," I have no doubt about the identification of his species; 
the description which he has given of it is very full, and in other respects, 
especially as to the position and character of the white spots, very accurate. 
The genus Rhaphidera, Newm., to which he referred the species, exists only as 
a narne ; it has never been characterized. In the Catalogue of Gemininger and 
Harold it appears as Bhaphidodera, Perroud, notwithstanding Perroud's state- 
ment that he was wholly ignorant of the characters of the genus.

distinct species, belonging perhaps to different genera, under the 
same name. The present species is quite distinct from all others

faintly covered in parts with golden pubescence. Antennae of $ 
one-third or so longer than the body ; first joint feebly punc- 
tulate; third slightly longer than the fourth, which is nearly 
one-third longer than the first; fifth subequal to the third. 
Prothorax about one-fifth longer than broad, slightly rounded 
at the sides; sparsely but strongly punctured, the sides and base 
covered with short grey pubescence which gives silvery reflec- 
tions. Elytra rather faintly covered with short, pale pubescence ; 
distinctly but not very densely punctured from the base to within 
one-fifth or one-sixth from the apex. Femora gradually and not

proportion to the third and fourth ; in the type and other closely 
allied species they are furnished with long projecting hairs, 
especially well marked at the apices of the third to fifth joints, 
where two or three coming off side by side have at first sight the 
appearance of a single thick hair or long slender spine. In the

180. Stenhomalus Y-pallidum, Motsch. (Phyton) Bull. Soc. Imp. 
Nat. de Moscott, p. 495 (1863). 

" Elongate, narrow, parallel-sided, depressed, sparsely punc- 
tured, very slightly nitid, fusco-piceous. Elytra with four whitish 
bands, oblique, joined angularly at the suture, the third strongly 
dilated, the fourth apical, interrupted at the suture ; eyes large, 
black, somewhat prominent, facetted, closely approximate, deeply 
emarginate ; antennas and legs ringed with whitish ; thorax 
narrower than the head, subcylindrical, rugose, clothed with 
sericeous pubescence, subnodose at the sides. Elytra scarcely 
broader than the head, parallel-sided, the apex rounded, sparsely 
pilose. 

" Very close to P. pallidum, Say, from North America, but the 
thorax is narrower and silky with the elytral bands more distinct, 
the second band curved so as to form a V." 

Length 5 ; breadth 1 J inni. 

Hab. Ceylon : Xewara-Eliya. 

I have not seen a specimen of this species, but judging from 
the description it is almost certainly a Stenhomalus, and as the 
eyes are closely approximate I have placed it in this section. 



B. Eyes smaller, rather widely separated above and below ; 
antennae without long projecting hairs. 

181. Stenhomalus lateralis, Pascoe (Obrium), Trans. Ent. Soc. (2) v> 
p. 26 (1850). 

Brownish testaceous ; prothorax with a dark brown band along 
each side ; elytra each with a dark brown spot near the shoulder, 
another near the suture at about one-third from the base, and a 
dark brown ring near the apex, the apex itself and the spot 
enclosed by the ring yellowish, the lateral border dark brown 
except near the base and apex ; antennaB with the first joint 
testaceous, the rest pale yellow; legs yellowish. Eyes rather 
widely separated above and below. Prothorax nearly twice as 
long as its width at the base ; very slightly protuberant on each 
side just before the middle, narrowed distinctly towards the base 
and very little in front. Elytra slightly dilated posteriorly; 
distinctly and rather thickly punctate from the base to the middle 
or a little past the middle, the punctures show a tendency to an 
arrangement in rows. 

Length 7 ; breadth 2 mm.

In this species the eyes are widely separated as in the genus 
Obrium, the antennae are without the characteristic long hairs 
of the type species, and the prothorax also is longer and not 
tuberculate at the sides.

Genus KUNBIR. 
Kunbir, Lameere, Ann. Soc. Ent. Bely. 1890, C. R. p. ccxiii. 

Type, K. teUphoroides, Lameere. 

Range. That of the type species. 

Allied to Merionoeda, Pasc., from which it differs by the following 
characters : Elytra much longer, completely or almost completely 
covering the abdomen, a little narrowed in the middle, not 
dehiscent, separately and rather broadly rounded posteriorly. 
Hind legs shorter; the femora extend only a little past the 
apex of the elytra, with the club less abruptly formed ; the tibiae 
asperate instead of spinulose, with two spurs at the end. 

This genus has been placed by Lameere in the group Cleomenini, 
but as it has the acetabula of the middle coxa? open to the epimera 
and the acetabula of the front coxae augulate on the outer side, 
it cannot rightly enter into that group. The structure of the 
abdomen in both sexes resembles that of Merionoeda, and in all 
other points, the length and form of the elytra excepted, there is 
a rather close resemblance between the two genera.

Group MYTHODIN1. 

Head exserted ; eyes lateral, finely facetted, entire, prominent, 
oval or rounded ; antennae approximated at base, inserted between 
the eyes, as far from them as from one another, certain of the 
joints tufted with hairs. Protborax longer than broad ; the sides 
rounded in the middle, feebly or not tuberculate. Mesonotum 
without stridulatory area. Front coxae globular, not prominent ; 
their acetabula angulate on the outer side, narrowly open poste- 
riorly. Acetabula of middle coxae extended to epimera. Femora 
pedunculate and clavate. Vein Cu 1 of hind wings simple, Cu 2 
absent. 

This small but remarkable group comprises only three genera, 
two of which occur in the Malay Peninsula, the third in Northern 
India and Upper Burma. In two of the genera (Mythodes and 
Phyodearia) the metathoracic episterna have each a small deep 
fovea near the hinder end. These foveae are in all probability 
scent-pores, notwithstanding their position, which is less close to 
the metasternal sutures than in other groups.

elytron, the red bands united 
along the sides and suture. 
Head very densely punctate. 
Antennae nearly twice as long 
as the body in large males, 
with the first joint densely

Scutellum rugulose-punctate. 
Elytra entirely opaque, rather densely punctate, the punctures 
visible only on the red anterior portion, not on the posterior 
black part, the latter rather densely covered with very short black 
pubescence. Mesothorax, metathorax and abdomen covered faintly 
with grey pubescence. Legs glabrous, glossy, very minutely and 
very sparsely puuctulate. 

c? . Head and prothorax of a dull red, slightly purplish, colour ; 
elytra entirely fulvous-red ; scutellum black ; antennae glossy, the 
first joint red, the rest black ; body beneath dull red, with the 
sides of the meso- and metathorax black ; femora red, except at 
the base ; tibiae and tarsi dark brown or black. Head subnitid at 
the sides, opaque above ; the clypeus and occiput rather densely 
punctate, the front almost impunctate. First antennal joint 
sparsely punctate. Prothorax very densely rugulose-punctate ; 
the disc less strongly raised than in the $ , but similarly provided 
with three subnitid tubercles, and with an obtuse, feebly elevated 
ridge behind each of the dorso-lateral tubercles. Elytra less 
closely punctured than in the $ . The male differs further from 
the female by the structural characters pointed out in the 
description of the genus. These characters, such as the great size 
of the head and mandibles, are most pronounced in large fully 
developed specimens, but are less obvious in males of minor 
development.

prothorax in both sexes, and in the elytra of the males, which are 
without spots posteriorly. The males appear to be much less 
numerous in collections than the females, and those described 
above are considered to belong to the species because they have 
coine from the same localities as some in the same collections. 



Group CALLICHROMINI. 

Head more or less distinctly raised between the antenna? ; 
the clypeus rather large, prolonged anteriorly some distance 
beyond the base of the mandibles ; eyes finely facetted, deeply 
emarginate, the lower lobes generally large, extending to the front; 
outer lobe of maxilla? long, with brush of hairs at the end ; 
maxillary palpi usually longer than the labial. Prothorax gener- 
ally tuberculate at the sides. Scutellum usually rather large, 
triangular in form, the sides straight or slightly curved, the apex 
acute. Front coxa? globular, not prominent ; their acetabula 
rounded on the outer side, closed, or very nearly closed, poste- 
riorly. Acetabula of middle coxae extended to the epimera. Legs 
long or moderately long ; their tibia? compressed. Metasternum 
provided with scent-pores. "Wings with vein Cu 1 simple, Cu 2 
absent. Male with six, visible ventral segments to the abdomen. 

This group is well represented in the African and Oriental 
Eegions, less well in Tropical America and by a few species only 
in the Holarctic and Australian Eegions. The species as a rule 
are characterized by a metallic coloration, varied in some cases by 
yellow or fulvous bands or spots on the elytra.

$ . Dark blue or violaceous-blue above, somewhat glossy, nearly 
bare of pubescence ; with two yellow bands that cross the elytra, 
the first nearly midway between the base and the middle, the 
second a very short distance behind the middle ; first five or six 

K" ints of the antennae black, the rest tawny ; body beneath steel- 
ue, glossy, very faintly pubescent ; legs black or bluish black, 
with the tarsi testaceous yellow. Puncturation of the head, pro- 
thorax, and elytra very much as in Z. favitarsis, Hope, but a little 
stronger and more conspicuous owing to the absence of a toinen- 
tose covering. Prothorax transverse, slightly protuberant at the 
middle of each side ; the disc with a slight transverse prominence 
on each side just in front of the basal constriction and with two 
feeble tubercles, more finely punctured than the rest of the surface, 
near the apex. Femora finely and rather sparsely punctate, the 
hind pair reach to a little beyond the hind border of the second 
elytra! band. 

Length 35-40 ; breadth 10-1 0| mm. 

Hob. Ceylon. 

In general form and structure this species comes very near 
Z. consanguineus, and is chiefly distinguishable from it by its 
larger size, by the upper surface which is almost bare of pubescence, 
and the puncturatiou, which is consequently much more distinctly 
visible. The author of the species has described the prothorax as 
elongate and strongly convex, but in the female at least the width 
across the middle is a littfe greater than the median depth, and 
the disc is not more convex than in other species, rather the 
reverse. 



208. Zonopterus corbetti, sp . n. 

Dark metallic green or blue, with two broad yellow bands of 
variable width on the elytra ; legs black, with the tarsi testaceous ; 
last five joints of the antennae testaceous ; the yellow elytral 
bauds in some specimens coalesce at the sides and suture and are 
so much extended that the elytra may be described as yellow, with 
the apical fourth, a narrow band at the base, and a transverse 
spot just before the middle of each, dark blue ; in other specimens 
the yellow bands are not broader than the sub-median blue baud 
which separates them, and become slightly narrower towards the 
suture ; the basal blue band and the sub-median band are slightly 
pointed posteriorly at the suture. Head closely and rather finely 
punctured. Antennae not so thick as usual for this genus, reaching 
to a little beyond the middle of the elytra in both sexes ; joints 
fifth to tenth feebly angulate in front at the apex. Prothorax 
closely and finely punctured above, sparsely beneath in the $ , 
very densely beneath in the d" . Elytra also finely and very 
closely punctured. Breast and abdomen with a fine grey

the rest black ; body beneath dark blue, sometimes almost black, 
with a faint covering of black pubescence. Head finely rugulose- 
punctate above and on the front ; the clypeus transversely but 
somewhat irregularly rugulose. Antennas extended only a little 
past the middle of the elytra in the $ ; fourth and fifth joints 
narrower than the third, very slightly angulate at the apex ; sixth

apex on the anterior side. Prothorax with a short obtuse tubercle 
at the middle of each side, densely rugulose-punctate above, some- 
what transversely rugulose near the basal margin ; its length a 
little greater than its width at the base. Seutellum subnitid.

Type, N. tricolor, Newin. 

Range. That of the type species. 

Though not considered distinct by Lacordaire, this genus 
differs from Pachyteria, Serv., by well-marked structural characters. 
The head is rather broad, and not narrowed and elongated 
in front ; the clypeus is short, with a slight projection at the 
middle of its front margin; the membranous epistome rather 
broad and the labrum small ; the mandibles are robust in the male, 
and differ in shape from those of Pachyteria the outer border 
of each forms an almost continuous curve and each is armed 
with a strong tooth on the inner side. The antennaa are very 
thick like those of Pachyteria but much shorter, those of the male 
not extending past the middle of the elytra ; they are gradually

Bitsema, while placing this species provisionally in Callichroma, 
considered that it ought perhaps to be made the type of a new 
genus. But I see no necessity for this, since the species, except 
for its slightly shorter mandibles and less strongly arched 
prosternum, possesses all the chief characters of Pachyteria.

large, depressed anteriorly ; epistome membranous, distinct ; 
labrum short and transverse ; genae rather short in front but 
prolonged downwards posteriorly ; mandibles moderately long,

angulate anteriorly at the apex. Prothorax with a transverse 
groove near the apex and another at the base ; strongly tuber- 
culate near the middle of each side and often tuberculate on the 
disc. Scutellum triangular. Elytra from two and a half to three 
times as long as they are broad, always extended some distance 
beyond the tip of the abdomen ; gradually narrowed posteriorly, 
rounded or subacuminate at the apex. Legs long ; the femora

a short abrupt slope to the posterior groove, strongly and closely 
punctured especially towards the sides, with the interstices 
generally slightly raised ; a faint median groove on the anterior 
part. Elytra nearly three times as long as their width across the 
base, with coriaceous surface sculpture somewhat coarser near the 
base and gradually finer posteriorly ; each narrowed to a point at 
the apex. Metasternum with some sparsely scattered setigerous 
punctures. Abdomen frequently testaceous on the anterior part of 
each of the three intermediate segments ; fifth segment in the male 
with a feeble sinuate etnargination at the apex, the sixth with a 
narrower and deeper emargination. Femora rather densely punc-

Metallic green, glabrous and glossy above with a slightly brassy

red or purplish-red ; tarsi fulvous yellow ; antennae with the first 
four or five joints green and subnitid, the rest dull black. Head 
almost impunctate in front, and the prothorax sparsely and not 
strongly punctured above ; the species in both these respects differs 
from A. cribricolle, van de Poll, with which in other points of 
structure, as well as in colour, it agrees very closely. Both may 
be distinguished from A. cantori, Hope, by the absence of an 
anterior tubercle from each side of the prothorax, by the postero- 
lateral part of the disc which is sharply ridged or tuberculated, 
and by the acuminate apices to the elytra : the males are further 
distinguished by the rather feeble, sinuate emargination at the apex 
of the fifth abdominal segment.

-so as to form an oblique ridge or tubercle on each side, and with 
also a feebler oblique ridge on each side anteriorly ; the lateral 
tubercle on each side placed slightly before the middle and not so 
strong as in the other species. Elytra rather more than three

on the pronotum with short velvety black tomentum ; elytra 
fulvous red, covered with very short pubescence of nearly the 
same colour, each marked with a more or less large violaceous-

CHELIDONIUM. 211 

Antennae rather slender, filiform, about equal in length to the 
body in the and a little longer in the d 1 ; the joints from the 
fifth or seventh to the tenth angulate or dentate at the antero- 
distal angle, third longer than the fourth, eleventh a little longer 
than the tenth. Prothorax transverse, tuberculate at the middle 
of each side. Elytra slightly and gradually narrowed backwards 
from the base, separately rounded at the apex. Front and middle 
legs moderately long, their femora subclavate ; hind legs much 
longer, their femora gradually thickened, reaching to or beyond 
the apex of the elytra in the <3 ; first joint of hind tarsus longer 
at least than the second and third united. 

The structural characters that distinguish this genus from 
Polyzonus, Casteln., are slight. They consist chiefly in the 
distinctly angulated or dentate joints of the antennae and the 
somewhat longer hind femora. The species with a few excep- 
tions are destitute of yellow markings on the elytra, whereas 
in Polyzonus nearly all the species are spotted or banded with 
yellow. 

Lacordaire, labouring under an error in regard to the genus 
Leontium of Thomson, placed Chelidonium in the same genus, 
making it his section B. Leontium, Thorns., has as its type L. viride, 
Thorns., a species from Japan (since described by Bates as Chlori- 
dolum temte), and is really very closely allied to, and scarcely 
distinct from, Chloridolum. 



233. Chelidonium argentatum. Dalm. (Cerambyx) Sdwnh. Syn. Ins., 
App. p. 151 (1817). 

Dark metallic green, and for the most part dull, above ; the 
underside of a brighter, glossier green, covered with a fine silvery- 
grey pubescence ; legs and antennae dark blue or violaceous, some- 
times partly green, the tarsi brownish black. Head densely 
rugulose-punctate with a smooth, transverse, slightly depressed 
space between the clypeus and front ; the front with a median 
linear groove which extends to the vertex. Antennae a little 
longer than the body in the 6 ; first joint nitid, densely punctate, 
fifth to tenth each with a sharp oblique spine at the apex on the 
anterior side ; third and fourth angulated at the apex. Prothorax 
with a conical but rather obtusely pointed tubercle on each side ; 
densely punctate and somewhat rugulose above, with a more 
densely punctate and less rugulose opaque area along each side of 
the middle, the rest subnitid. Scutellum smooth and glossy. 
Elytra very densely and rather finely rugulose-punctate, and for 
the most part dull ; rather narrowly rounded at the apex. Femora 
finely and densely punctate ; the hind pair extending a little past

Structurally and in colour very like 0. argentatum, Dalm., but 
differs from that species as follows : The elytra marked each 
between the base and the middle with a yellow band of irregular 
form, the band transverse on the inner half of the elytron and 
prolonged a little posteriorly near its outer side. Head impressed 
with a transverse line between the front and clypeus. Pronotum 
transversely rugulose or striate at the sides ; with a median 
subnitid band which extends almost from base to apex, and is 
sparsely punctured posteriorly, nearly smooth in front ; and, at 
each side of this band, a darker area which is finely and somewhat 
intricately rugulose. Scutellum nitid, with the edges slightly 
raised posteriorly. Elytra rugulose anteriorly near the suture, 
elsewhere very densely punctulate ; the yellow bands clothed with 
yellowish or tawny pubescence, and with the parts bordering on 
them blackish in colour.

Form and coloration of C. argentatum Dalm., a species with 
which it had been for a long time confounded, but from which it 
differs as follows : AntennaB with joints seventh to tenth sharply 
angulate or dentate at the apex on the anterior side, not spined 
as in argentatum ; last ventral segment of the $ with a distinct 
emargination at the apex. The head is rather finely punctate on 
the front, the clypeus more coarsely punctate and somewhat 
transversely rugulose, and there is no smooth space between the 
clypeus and front. The prothorax is distinctly rugulose and glossy 
at the sides and base and along the median line ; the dark opaque 
area along each side of the middle line is generally well-marked 
and more distinct than it is in argentatum. The first joint of the 
hind tarsus is almost or quite as long as the remaining joints 
united. The elytra are obtusely rounded at the apex.

Var. megaspilus, nov. 

In the sculpture of the prothorax and in coloration very like 
the type, but with the yellow spots of the elytra larger and less 
oblique ; the anterior spot extends to the outer margin but not 
quite to the suture and has its borders more or less angulated ; 
the posterior spot reaches from the outer margin to the suture, 
and thus forms a complete band across the elytron, its hind 
margin sinuate or oblique and its front margin angled on the 
middle of the disc. This variety attains to a larger size than the 
type, and seems to be limited in its range to the southern part of 
India.

Hob. Mysore ; Malabar ; Nilgiri Hills. 

Var. microspilus, nov. 

This variety differs from the type not only by the smaller size 
of the yellow spots on the elytra, but to some extent also in the 
sculpture of the prothorax. The anterior yellow spot is rounded 
or obliquely oval, and about equally distant from the suture and 
the outer margin ; the posterior spot is oblique, and reaches 
almost or quite to the outer margin but not to the suture, its 
inner end rounded and slightly distant from the suture. The 
prothorax is regularly striate at the sides and near the front 
margin as in the type ; but on the middle of the disc the striae 
are more or less interrupted or broken, a somewhat irregularly 



216 CEBAMBYCID.S. 

rugulose appearance replaces the regular radiating lines and curves 
seen in the type and in the var. megaspilus. The present variety 
was regarded by White as the tetraspilotus of Hope, and the true 
tetraspilotug he described as a distinct species under the name of 
quadrimaculatus. It does not differ in size from the typical 
form. 

Hob. Assam : Sylhet, Cherra Punji, Khasi Hills. 

Var. macrospilus, nov. 

Resembles the type in form, colour and sculpture, but differs 
in that each of the four spots on the elytra is elongate-elliptical 
in form with its longer axis longitudinal, nearly equidistant from 
the suture and the outer inargin, and the two posterior spots are 
more than twice as long as they are broad.

239. Polyzonns flavocinctus. Gahan, Ann. Mus. Civ. Genov. xxxiv,

Metallic green ; the elytra with two rather narrow, transverse, 
yellow bands placed at about one-fourth from the base and the 
other about one-third from the apex, the parts of the elytra that 
border on the bands violaceous black. In structural characters, 
and in the sculpture of the head, prothorax and elytra, it agrees 
closely with P. tetraspilotus, Hope, of which it may perhaps be 
only an extreme variety in which the spots are replaced by 
complete bands ; these bands are, however, directly transverse 
rather than oblique. From P. bizonatits, White, which it 
resembles more in the banding of the elytra, it may be readily 
distinguished by the regular radiating striae on the disc of the 
prothorax, and the glossy rugose area at the base of the elytra 
that surrounds the scutellum and extends a short way back along 
the suture.

sparsely covered with short black pubescence ; the sides less 
densely punctate and somewhat smooth in places. Elytra finely 
and very densely punctulate ; covered, except on the yellow bands, 
with a short dark pubescence which more or less obscures the

The species of this genus have a considerable resemblance in 
form and colour to those of Polyzonus, but may be readily dis- 
tinguished from them by the completely unarmed prothorax, 
shorter hind femora, and in most cases also by the form of the 
antennas, the last two or three joints of which are gradually 
thicker than those that precede them.

249. Annbis fimbriatus, Sates, Cist. Ent. ii, p. 412 (1879). 

This species is very closely allied to A. bipustulatus, Thorns. ; it 
agrees completely with it in structural character and in the 
sculpture of the various parts. The only difference observable is 
in the markings of the elytra, which take the form of two trans- 
verse yellow or fulvous bands, more or less interrupted at the 
suture ; the posterior band occupies the same position on each 
elytron as the posterior spot in bipustulatus, and the anterior band 
replaces the one or two small spots sometimes seen in the latter 
species. The parts of the elytra bordering on the bands are dark 
violaceous in colour. The species has been found in the same 
localities as bipustulatus, and must be regarded as doubtfully 
distinct.

gradually shorter, compressed and dilated, produced each into a 
short angular process at the apex on the anterior side, eleventh 
scarcely longer than the tenth. Prothorax armed with an obtuse 
conical tubercle at the middle of each side. Elytra moderately 
long, more or less parallel-sided, rounded at the apex. Hind legs 
much longer than the middle pair, and these a little longer than 
the front legs ; femora distinctly but not abruptly clavate, sub- 
pedunculate at the base, the hind pair reach almost to the apex of

Pascoe, in describing this genus, stated that the unique type 
specimen of /. femorata appeared to him to be a male. In this he 
was mistaken. The type is undoubtedly a female, as is also the 
unique type specimen of /. pyrrJia, Pasc. Lacordaire knew only 
the first of these two species, and appears to have shared Pascoe's 
mistake in regard to the sex, since the characters given by him for 
the male are really applicable to the female.

downwards only in the anterior fifth or so of their length, but 
provided with very distinct epipleures in all their length, the 
lateral margin somewhat rounded anteriorly, slightly sinuate 
near the middle, straighter posteriorly. Front and middle legs 
moderately long, with the femora subfusiform ; hind legs much 
longer, with the femora more slender, gradually thickened towards 
the apex and extended beyond the apex of the elytra, all the 
femora carinate on each side near the lower border ; first joint 
of hind tarsus laterally compressed, longer than the remaining 
joints united. Prosternurn vertically deflexed posteriorly. Front 
coxa? rounded, with their acetabula closed posteriorly ; acetabula 
of middle coxae open to the epimera. Abdomen convex, the first 
ventral segment as long at least as the next two united. 

I have not seen any males of this genus ; and Lacordaire's 
description of it appears to me to have been based upon female 
specimens only, which he erroneously considered to be males. 
The male has probably the antennae relatively longer than in the 
female, the first abdominal segment not so long in proportion 
to the other segments, and the sixth segment visible as in the 
males of the allied genus Blemmya, Pasc.

Type, P. signata, Pasc., a species from North China. 

Range, Bhutan, Assam, North China, Malay Peninsula and

Closely allied to Homalomelas, "White, from which it differs 
chiefly by the structure of the elytra. These have narrower and 
less distinct epipleures, and the sides extend downwards near the 
base only to a slightly greater extent than in the rest of their 
length, so that the lateral margins are but feebly sinuate and 
nearly straight. The prothorax is relatively shorter and broader 
than in Homalomelas, and is not wrinkled or granulated above. 
The one species included in the Indian fauna is in form, colour 
and markings somewhat suggestive of a Clytid. 

265. Prothema aurata, sp. n. 

$ . Black, densely covered above with silky pubescence of a 
somewhat golden yellow colour, and marked with some densely 
punctured glabrous black bands : the body beneath covered with 
pubescence, which is yellowish towards the sides, ashy-grey in 
the middle. Antennae of the $ slightly longer than the body, 
with the proximal three or four joints black, the rest brown, all 
faintly covered with pale grey pubescence ; 
joints sixth to tenth rather sharply angu- 
lated anteriorly at the apex. Prothorax 
not longer than broad, gradually narrowed 
anteriorly, slightly constricted at the base ; 
the disc with two black bands that run 
forward from the base and slightly con- 
verge anteriorly, but do not reach quite to 
the front margin ; the sides each with one 
black band that extends from the base to 
a little beyond the middle. Elytra with 
the sutural and lateral margins black, 
marked each with a black baud that runs

236 CEEAMBTCID^E. 

Group THRANIINL 

Head rather strongly sloped above ; the front vertical, flat, 
large and rectangular ; eyes finely facetted, feebly emarginate, 
the upper lobe very short ; gula without mentigerous process. 
Antennae cylindrical, shorter than the body in both sexes. Pro- 
thorax parallel-sided, the disc more or less raised in front. Elytra 
long, deflexed at the sides only where they cover the thorax, flat, 
narrow and more or less dehiscent posteriorly, acuminate at the 
apex. Femora clavate, the hind pair much shorter than the 
abdomen. Front coxae rather prominent, contiguous, their 
acetabula open posteriorly. Acetabula of middle coxae extended 
to the epimera. Episterna of metathorax very broad in front, 
gradually narrowed to a point posteriorly. Wing-vein Cu 1 
simple, Cu 2 absent. 

This group is formed for a single genus, Thranius, Pasc., which 
was included by Lacordaire in his group Necydalides. The 
affinities of this genus are doubtful, but it certainly cannot be 
associated with Necydalis, a genus which is now generally recog- 
nised as belonging to the Lepiuriiue.

Banye. Oriental Eegion and Japan. 

Head strongly inclined above ; front vertical, flat and sub- 
quadrate ; palpi short ; eyes rather large and prominent, feebly 
emarginate, with very short upper lobes which do not extend 
behind the antenniferous tubercles, the latter somewhat prominent 
on the inner side. Antennae extended to the apical fifth or fourth 
of the elytra in the <3 , and a little past the middle in the $ ; 
the joints cylindrical, first slightly curved, third as long as the 
fourth and fifth united ; fourth to tenth subequal in length, 
eleventh a little longer than the tenth. Prothorax parallel-sided, 
scarcely longer than broad ; the disc raised in front so as to form 
a more or less distinct laterally compressed gibbosity. Elytra 
elongate, almost flat above, deflexed at the sides only where they 
cover the thorax, narrowed from the base up to the middle or 
nearly so, and thence either parallel-sided or gradually widened 
to within a short distance of the apex, each acuminate at the apex, 
usually ended in a spine. Front coxae contiguous, their acetabula 
open posteriorly ; acetabula of the middle coxae extended to the 
epimera. Femora clavate, the hind pair much shorter than the 
abdomen ; tarsus of the hind legs about half the length of the 
tibia, with the first joint as long as the next two united. Episterna 
of metathorax very broad in front, narrowed almost to a point 
posteriorly.

Singalia spinipennis, Lacord. Gen. Coleopt. ix, p. 835 (1872). 

Fulvous or testaceous ; the head marked in front with a median 
dark brown line or band ; prothorax brown above ; elytra with a 
large brown spot at the base surrounding the scutellum, a dark 
brown patch on each before the middle and another behind the 
middle ; these dark brown areas so variable in extent that in some 
specimens the elytra might more fitly be 
described as dark brown, with an arcuate 
fulvous band near the base, another at the 
middle, and the apex also broadly fulvous ; 
antennae dark brown, with the eighth and 
ninth joints pale fulvous. Pronotum raised 
in front in a rather strong laterally com- 
pressed gibbosity, which is finely asperate 
on top. Elytra densely and somewhat 
asperately punctured, approximate at the 
suture for almost their whole length, 
gradually narrowed from the base to the 
middle, and thence to the apex of almost

Dark brown, or sometimes almost black in colour ; the head 
and prothorax faintly clothed with yellowish pubescence; the 
breast in the middle and the abdomen testaceous ; the legs more 
or less testaceous, with the clavate portion of the femora and the 
tibiae in part piceous or black ; antennae dark brown or black, with 
the eighth and ninth joints fulvous yellow. Antennae extended 
to the apical fifth of the elytra in the <3 , and to the apical third 
in the $ ; first joint closely and rather finely rugulose-punctate. 
Prothorax with a strong, laterally compressed gibbosity on the 
fore part of the disc which is subvertical in front and almost 
horizontal above ; the gibbosity rather densely asperate. Elytra 
approximate at the suture for almost their whole length ; nar- 
rowed slightly from the base for about one-third of their length,

Bab. British Bhutan (L. Durel in coll. Oberthiir) ; Manipur

In structural characters, such as the form of the gibbosity on 
the prothorax and the shape of the elytra, this species agrees 
pretty closely with T. gibbosus, Pasc. The examples from Bhutan 
which 1 have seen are much darker in colour than those from 
Manipur and Burma, and constitute a variety to which the name 
nigrescens may be given. 



II. Elytra dehiscent from before the middle each less than half as 
bread at middle as at base. 

268. Thranius triplagiatus, sp. n. 

Head, prothorax and body beneath fulvous, with a not very 
dense covering of fulvous yellow pubescence ; antenna? black ; 
elytra fulvous, each with the greater portion of the apical half, a 
transverse spot at the base and a large rectangular spot at the 
side a little behind the base, black. Antenna? of the $ extended 
to a little beyond the middle of the elytra ; the first joint rugose- 
punctate. Disc of prothorax strongly but somewhat obtusely 
raised along the middle, sloped gradually posteriorly and more 
abruptly in front, its surface more or less asperate. Elytra 
dehiscent at about one-sixth of their length from the base ; each 
narrowed thence up to about the middle of its length, and then 
gradually widened up to the apex, ending in a short point, not 
in a spine as in other species of the genus ; the width of the 
elytron at the middle less than half what it is at the base ; the 
surface rather densely asperate-punctate, with the dark areas more 
densely punctured. 

Length 20 ; breadth 5 mm. 

Hab. Manipur (Doherty}. 

269. Thranius fryanus, sp. n. 

Reddish brown ; the elytra paler, but marked each with a dark- 
brown spot behind the scutellum, another on the disc a little 
before the middle, and a dark longitudinal band that extends 
backwards from the middle and disappears before it reaches the 
apical dilated part ; antennae dark brown, with the first two joints 
and the greater part of the third reddish. Antennae of $ ex- 
tended only a little past the middle of the elytra ; first joint 
densely and rather strongly punctured, second and third less 
densely and less strongly punctured ; fourth to eleventh and apex 
of third very minutely and densely punctulate. Prothorax 
relatively rather broad ; with the disc obtusely and not very 



strongly raised in front, rather densely asperate and very faintly 
pubescent ; the sides clothed with pubescence of a pale golden 
colour. Elytra narrowed from the base to the middle, approximate 
at the suture only in the anterior sixth of their length ; each less 
than half as broad at the middle as at the base, narrow and of 
almost equal width from the middle up to about one-seventh of its 
length from the apex, then widened slightly, acuminate and ended 
in a sharp spine at the apex ; the surface rather densely asperate- 
punctate, the punctures denser on the dark ante-median spot and 
posterior band. Sides of breast and abdomen with pale golden 
pubescence mixed with longer grey hairs. 

Length 20 ; breadth 4| mm.

Group GLYTINI. 

Head short, vertical or subvertical in front ; gense generally 
rather long ; eyes finely facetted, emarginate ; mandibles short ; 
palpi short, subequal, the last joint more or less triangular. Pro- 
thorax usually unarmed at the sides, varying in form from globular 
to cylindrical. Scutellum generally small. Front coxae globular, 
as a rule not prominent ; their acetabula rounded on the outer 
side, open posteriorly. Acetabula of middle coxoa open to the 
epimera. Hind legs generally long, the first joint of the tarsus 
much longer as a rule than the second and third .united ; spurs of 
hind tibiae long. Tarsal claws widely divergent. The episterna 
of the metathorax generally rather broad, but in some forms more 
or less considerably overlapped by the sides of the elytra. 

In this group I include the Clylides and Anaglyptides of Lacor- 
daire, together with the genus Demonax of Thomson. Lacordaire's 
restriction of the group, on the one hand, to forms in which the 
antenna? are at most only a little longer than the body in the c? , 
and, on the other, to those in which the first joint of the hind 
tarsi is distinctly longer than the next two joints united, is one 
which cannot be maintained. Within the group there is a regular 
gradation in the length of the antennae from forms in which these 
organs are less than half the length of the body to others in which 
they are more than twice as long as the body ; and so also in regard 
to the hind tarsi, the first joint is in some forms scarcely longer 
than the second, in others more than three times as long as the- 
second and third united, while between the two extremes there is 
almost every intermediate degree. On account of the gradual 
modifications not only in these but in many other points of struc- 
ture, the genera cannot be defined with any great amount of 
precision. In fact there is something to be said in favour of 
those entomologists who describe each new species of the group as a 
Clytus. The chief objection to this course is that, unless the 
structural characters are given somewhat in detail, it becomes 
quite impossible to identify the species.

This species varies considerably in colour and to some extent 
also in the markings. In some specimens the derm is of a 
yellowish-testaceous colour in parts, in others almost entirely 
dark brown. The pubescence is sometimes yellowish, some- 
times ashy grey. The postmedian band of the elytra is often 
interrupted or broken up into spots, and occasionally almost

Dark brown, with a tawny or greyish-tawny pubescence that 
covers the head and prothorax and forms bands on the elytra ; 
prothorax with a median asperate band which is widened towards 
the base, two lateral spots on the disc, and a small spot on each 
side, black ; the elytral bands arranged as follows : (1) a band 
which crosses the base of each elytron from the shoulder, curves 
backwards near the scutellurn and runs close along the suture 
for a short distance, then diverges from the suture and curves 
outwards to the side at about one-third from the base, turning 
forward a little before it reaches the outer margin ; (2) a short, 
slightly oblique, transverse band on each a little behind the base ; 
(3) a band that passes obliquely outwards from the suture at 
about two-thirds of its length from the base : (4) a band at the 
apex. Body beneath with a large spot of yellowish-white pubes- 
cence on the hinder half of each of the metathoracic episterna, 
sometimes with a smaller spot on the anterior part ; a lateral 
transverse spot of the same kind on the posterior half of each of 
the first three abdominal segments. 'Vertex of head with a fine 
median carina which divides anteriorly into two finer ones ; front 
with four carinse, the lateral pair extended downwards as far as 
the middle of the front border of the eyes ; the intermediate pair 
converge and unite below so as to form a single median carina on 
the clypeus. Antennae reach a little past the base of the pro- 
thorax in the $ , slightly longer in the <$ ; the last two or three 
joints somewhat thickened. Prothorax rounded at the sides, 
widest behind the middle, narrowed gradually in front, more 
strongly towards the base.

XILOTBECHUS. 243 

This species is very closely allied to X. smei, Lap. & Gory, the 
differences which it presents are very slight. It is generally 
darker in colour, and the basal band of each elytron curves round 
by the scutellum and is continuous with the sutural band.

Closely allied" to X. smei, Lap. & Gory, and X. subscutellatus, 
Chevr. This species differs from both in that the white spot on 
the anterior part of each of the metathoracic episterna is nearly as 
large as the spot on the posterior part, also the two spots are 
joined. The elytra are light brown or slightly reddish in colour 
in the neighbourhood of the anterior, sutural band ; this lighter 
coloured part is somewhat in the shape of a triangle with its base 
in front.

the head and prothorax and is formed into bands on the elytra ; 
prothorax without spot at the sides, the disc with a median band, 
which is widened and somewhat rounded at the base, narrowed in 
front, and two large lateral spots, black ; elytral bands arranged 
as follows : (1) a transverse band at the base ; (2) a short sutural 
band which begins at a little distance behind the scutellum, at its 
hind end turns outwards almost at right angles and then passes 
straight across the elytron to the side ; (3) a short transverse 
band a little behind the base, which is bent backwards at its outer 
end and almost touches the sutural band ab its inner end ; (4) a 
transverse band at about one-third from the apex, this band pro- 
duced forward in a triangle at the suture and sometimes also 
angulated behind at the suture ; (5) an apical band produced at 
the suture, with its front border strongly oblique. Body beneath

" Closely resembles C. speciosus dark brown in colour and 
densely pubescent. Head and antennae very short, covered with 
white pubescence, the former with isolated erect long hairs. 
Thorax cylindrical, with a slender elongated callosity in the middle, 
often coarsely punctured and very densely pubescent ; in colour 
grey, except at the base and the lateral margins which are bordered 
with white ; this white edging in two specimens extends only 
along half the leugth of the thorax. Elytra flat, parallel-sided, 
ending posteriorly in two slender short spines, densely punctured, 
clothed with dark brown pubescence, marked with white as 
follows : a somewhat dusky white crescentic band close to the 
base across the elytra, over the suture, and extended almost to 
the underside ; another that starts from the scutellum, along the 
suture, and at about one-third of the length of the elytra diverges 
sharply across at a right angle ; following that a straight trans- 
verse band crosses the whole breadth of the elytra ; finally, two 
white marks at the apex of the suture that are connected along 
the suture with the above by a white streak. Underside slightly 
shining, very finely punctured and clothed with blackish-brown 
pubescence ; the long lees show similar sculpture, especially in 
those forms in which the hind pair are strikingly elongated.

Perissus, Chew. Mem. Soc. JR. Sci. de Ltige, xviii, p. 262 (1863). 
Amaursesthes, Chevr. (in part.) 1. c. p. 327. 

Type, P. X-littera, a species from the Aru Is. 

Range. Oriental and Austro-Malayaii .Regions ; Kashmir and 
Europe. 

Head very slightly or not at all raised at the sides between the 
antennae, the latter rather widely separated at the base, the distance 
between them almost or quite as great as that between the lower 
lobes of: the eyes ; face rectangular, not carinate. Antennae 
variable in length, sometimes nearly as long as the body, generally 
very much shorter. Hind femora extend as a rule past the apex 
of the elytra in both sexes. 

The structural differences between this genus and some of the 
forms included in Xylotrechus are very slight. The lateral edges of 
that part of the front which lies between the antennae are sharp 
and slightly raised, as in Xylotrechus, but do not extend down- 
wards to the eyes, and form merely the inner rim of the condylar 
cavities. The face has no median carina. The prothorax is 
usually longer and more cylindrical than in Xylotrechus, and the 
hind femora extend farther beyond the apex of the elytra. 



289. Perissus fuliginosus, Chevr. (Arnaurassthes) Mem. Soc. R. Sci. de 
Lieye, xviii, p. 328 (1863). 

Head and prothorax black, with a very faint covering of grey 
pubescence. Elytra dark brown, marked with very narrow bands 
of ashy-grey pubescence ; the first band begins a little behind the 
scutellum, diverges from the suture as it runs backwards some 
distance, and is then curved round so as to extend outwards and a 
little forwards to the side, where it is again bent back just before 
it reaches the outer margin ; the second band curves obliquely 
backwards and outwards from the suture behind the middle, and 
is interrupted near the middle of its course ; the third band 
consists sometimes of two small transverse spots on each elytron, 
and is placed at a short distance before the apex. Antennae extend 
a little past the middle of the elytra in the c? , not so far as to the 
middle in the ; the first four joints brown and glossy, the rest 
dull, covered slightly with grey pubescence. Prothorax widest 
behind the middle, narrowed strongly at the base, gradually 
and slightly in front ; the disc rather strongly asperate and 
slightly raised along the middle. Hind femora extend past the 
apex of the elytra slightly in the $ , by nearly a third of their 
length in the c? . 

Variation. The elytra are sometimes of a paler (somewhat 
reddish-brown) colour between the base and the first baud.

(1804). 

c? . Black ; head and prothorax faintly covered with grey 
pubescence, the prothorax with two black spots or a single large 
transverse one on the middle of the disc ; scute] him black, bordered 
with ashy grey. Elytra blackish brown, marked with ashy-grey 
bands ; the first band crosses at the base from the scutellum to the 
humeral depression, and is there turned slightly backwards ; the 
second begins at the suture a little behind the scutellum, diverges 
from the suture as it passes backwards for some distance, then 
curves round and takes an anterior and outward direction, where 
it is again sharply bent backwards just before it reaches the outer 
margin ; the third band is placed just behind the middle, it is 
narrow and slightly oblique in its outer half, produced in an angle 
both anteriorly and posteriorly at the suture ; the fourth is a 
rather broad, somewhat oblique band placed at the apex. Body 
beneath closely covered with ashy-white pubescence ; legs black, 
faintly covered with grey pubescence. Prothorax rounded at the 
sides, widest just behind the middle ; strongly but rather sparsely 
asperate above. Antennae reach a little past the middle of the 
elytra. The hind femora extend past the apex of the elytra by 
nearly one-third of their length. 

5 . Elytral bands similar in form and position to those of the c? , 
but of a yellowish-grey instead of an ashy-grey colour. Prothorax 
with an ill-defined, slightly curved, longitudinal band of yellowish- 
grey pubescence along each side of the disc. Antennae not reaching 
to the middle of the elytra. The hind femora are more slender 
than in the rf and extend only a little past the apex of the elytra. 

The single specimen described by Lameere has the elytral bands 
coloured as in the , and has also two yellowish-grey bands on 
the prothorax. He may possibly have been mistaken in regarding 
the type as a d ; but it is not very unusual to find specimens of 
both sexes sometimes coloured alike in species where usually there 
is a sexual difference in coloration.

Yar. adhcerens. Agrees with the type in structure and colour, 
but differs in the form of the second and third elytral bands. 
The second band begins behind the scutellum, remains close to the 
suture as it passes backwards, and becomes gradually wider poste- 
riorly ; it then gives off a curved branch which follows the same 
course as the corresponding band in the type ; the third band, that 
behind the middle, is not dilated in the form of a triangle at the 
suture, but is somewhat arcuate in shape, broader in the middle 
and narrowed at the sides ; a very narrow sutural band extends 
from it in front, and another posteriorly.

pubescence the first band extends transversely at the base for a 
short distance from the scutellum, which also is ashy grey in 
colour ; the second band begins at the suture a little behind the 
scutellum, curves backwards to the middle of the disc, which it 
reaches at about one-third from the base, and then bends round so 
as to run obliquely towards the outer margin ; the third band is 
placed transversely at a short distance behind the middle, and 
gradually widens out towards the suture ; the fourth band is at 
the apex. Body beneath ashy grey, whitish at the sides of the 
metathorax and abdomen, with a white spot on the mesotho- 
racic episterna. AntennaB slightly longer than half the body in

Type, C. speciosus, Schneid., a European species. 

Range. Palaearctic and Oriental Eegions, a few species occur in 
Australia and Africa. 

Head with a slight, subacute elevation on each side between the 
antenna. Antenna rather closely approximated at the base, the 
distance between them distinctly less than that between the lower 
lobes of the eyes ; variable in length, but nearly always shorter 
than the body, very rarely extending to the apex of the elytra in 
the <3 , not spined at the apex of the joints. Prothorax oblong- 
oval or subglobular, longer than broad. Elytra moderately long, 
truncate at the apex, with the outer angles dentate. Femora 
more or less gradually thickened ; the hind femora usually extend 
past the apex of the elytra in both sexes ; middle femora in many 
of the species, the hind pair also in some, furnished with a fine 
carina along each side. First joint of the hind tarsi much longer 
as a rule than the next two joints united. 

This genus includes a very large number of species, which are 
generally a little narrower and less robust than those of Clytus and 
Xylotrechus, with the antenna? somewhat longer, less thick, and 
much more closely approximated to one another at the base. In 
the type, C. speciosus, the antenna are longer than usual, and in 
other respects also this species is by no means typical of the great 
majority of the forms included in the genus. The name Clytan- 
thus, Thorns., by which the genus is generally known, has a 
doubtful priority over Caloclytus, but should, in my opinion, be 
restricted to certain Central- American forms that agree in struc- 
ture with C. tricolor, Chevr., the species indicated by Thomson as 
the type of his genus.

follows: three spots on the pronotum one median, bifurcated 
posteriorly, and one, obliquely oval, on each side before the 
middle ; two bands and a rounded spot on each elytron, the first 
band somewhat elliptical in form, with its longer axis extending 
from near the shoulder to the middle third ; the second band 
transverse, submedian, curved forwards along the suture about 
halfway to the base, expanded at its outer end into an oblique 
spot which reaches to the elliptical band in front and is united 
to it by a narrow point ; the round spot lies about midway between 
the submedian band and the apex, and approaches more closely to 
the outer margin than to the suture. Body beneath with a dense 
whitish pubescence that covers almost the whole surface in the 
c? , and forms more or less extensive spots at the sides in the $ ;

DEMONAX. 281 

Many of the species included in this genus are narrow and 
elongated like those of lihaphuma, Pasc. ; others, with subglobose 
prothorax and relatively shorter elytra, resemble the majority of 
forms belonging to the genus Calodytus, Fairm. They are dis- 
tinguished from both the above genera by the presence of spines 
at the apex of the third, fourth and sometimes also the fifth and 
sixth antennal joints. In certain species such as those on which 
the genera Grammoyraplius and Elezira were founded, the antennal 
spines are very minute and liable to be overlooked without close 
examination under the lens ; in the majority they are quite distinct. 

The lateral margins of the elytra are in the more typical forms 
nearly straight, and the metathoracic episterna appear broad and 
parallel-sided ; in others the lateral margins are more or less dis- 
tinctly sinuate near the middle, and the metathoracic episterna 
appear narrowed in front and widened out posteriorly.

crosses transversely a little in front of the apical third, at the 
suture it is produced in front as a very narrow band, and is some- 
times also produced posteriorly; the apex is rather broadly 
covered with a baud of ashy-grey pubescence, from which a 
narrow sutural band of whitish pubescence extends in front.

the meso- and metathorax and the sides of the abdomen more 
densely covered with whitish pubescence. Antennae black, faintly 
covered with grey pubescence ; a little longer than the body in 
the o , shorter in the $ ; third and fourth joints very feebly 
spined at the apex. Prothorax much longer than broad, slightly 
rounded at the sides ; the disc with a median and two feebler 
lateral elevations, the surface asperate, especially along the median 
band. Legs black, rather faintly covered with grey pubescence ;

base, and is followed by a small sutural spot to which it is some- 
times joined, three spots are placed in a transverse row at the 
middle or a little before it, and three smaller spots form another 
transverse series at a short distance behind the middle; the

three spots in front there are two oblique, very slightly curved 
bands which meet at the suture ; occasionally, however, these 
bands are slightly interrupted, appearing then as three spots.

377. Epipedocera laticollis, sp. n. 

Closely allied to E. zona, Chevr., which it resembles greatly in 
colour and markings, but has the prothorax relatively broader and 
somewhat different in form. The prothorax is strongly, but very 
obtusely, protuberant at the middle of each side, with a distinct 
constriction at the apex as well as at the base, though less deep ; 
its width across the middle is equal to, or even slightly greater 
than, that of the elytra at the base, and distinctly greater than its 
length along the middle ; it has, as in E. zona, a narrow glossy 
band at the base, that borders the basal emarginatipn, the rest of the 
surface reticulately punctate and dull. The species is smaller on 
the average than E. zona, and differs further in the absence of pubes- 
cent bands on the second and third segments of the abdomen ; the 
latter segment very sparsely furnished with long whitish hairs.

Type, C. quadridens, Motsch. 

Range. Ceylon, Andaman Is., and Malay Peninsula. 

Agrees generally in form and structure with Epipedocera, Chevr. ; 
the following characters, however, serve to distinguish it from 
that genus : Second joint of the antenna much longer than broad, 
nearly half as long as the third ; mesonotum provided with a 
stridulatory area ; elytra furnished each with a rather sharp lateral 
carina, reaching nearly to the shoulder in front and to within a 
variable distance of the apex posteriorly. 

The type species of this genus looks like a small Epipedocera and 
was, in fact, included in that genus by Chevrolat, who thereby 
clearly recognized its true affinities. It is remarkable, therefore, 
that both by Thomson and Lacordaire it was placed in a group 
widely separated from Epipedocera and its allies.

much shorter. Prothorax longer than broad, rounded at the sides, 
deeply constricted at the base ; the surface dull, very closely 
covered with shallow punctures, the interstices forming a fine 
reticulation ; the base broadly but not deeply emarginate in the 
middle, and expanded in a short broad lobe at each side. Elytra 
slightly raised near the base, depressed and somewhat constricted 
at the middle where the ivory band crosses ; the surface strongly 
but somewhat irregularly and not very closely punctured ; sub- 
nitid posteriorly, duller near the base ; each narrowly truncate

regarded as a subgenus differentiated by the following characters : 
Prothorax longer than broad, not strongly rounded at the sides ; 
elytra furnished each with a somewhat feebly raised lateral carina ; 
femora less strongly thickened, the hind pair not reaching to the

basal margin straight and entire ; elytra rounded and unarmed at 
the apex ; intercoxal part of the mesosternum only moderately

IRESIOIDES. 319 

392. Nida andamanica, sp. n. 

Very like N. flavovittata, Pasc., but differs from it by the absence 
of the testaceous band along each elytron, and in the C-shaped 
white band at each side of the prothorax which is less distinctly 
marked ; the anterior part of this band widened out and greyish, 
rather than white, in colour. The testaceous band of JV. flavo- 
vittata replaced by faint grey bands, formed of pubescence the 
hairs of which lie somewhat transversely ; the underlying derm, 
however, is as a rule quite black, although a small testaceous spot 
is in some specimens visible near the base. 

Length 11-14 ; breadth 2-2% mm. 

Hob. Andaman Islands. 

As this form agrees structurally with N. flavovittata, it ought, 
perhaps, to be regarded as a race or local variety of that species, 
sufficiently different in colour to be entitled to a distinctive 



Group GLAUCYTINI. 

Head short, slightly concave or sometimes nearly flat between 
the antennae ; front vertical, somewhat narrowed between the 
e} r es, especially in the male ; eyes large, prominent, finely facetted, 
deeply emarginate ; antennal supports emarginate in front. An- 
tennse longer as a rule than the body in both sexes. Prothorax 
subcylindrical, unarmed at the sides. Front coxae globular, their 
acetabula rounded on the outer side, closed or very nearly closed 
posteriorly. Acetabula of middle coxae not open to the epimera. 
Legs variable in length ; the femora more or less distinctly 
thickened towards the apex ; the hind tarsi not long, the first joint 
very little (sometimes not) longer than the second and third 
united. Vein Cu 1 of wings simple ; Cu 2 absent.

Very like /. moesta, Pasc. ; differs only in the elytra, which are 
uniformly pubescent, _ not banded in any way, the pubescence 
somewhat shorter and less glossy. In the male the antennae are a 
little longer than the body and the last ventral segment is covered 
by the elytra.

It is probable that this species, founded upon male specimens 
only, is not distinct from J. moesta, Pasc., and that the differences 
between the two are entirely sexual.

closely approximated at the base, sometimes even united there. 
Elytra claret-coloured, faintly covered with golden-tawny pubescence 
which is visible only in reflected light, each elytron marked at the 
base with a short longitudinal band of denser golden pubescence,
