Longicornia Malayana; or, a Descriptive Catalogue of the

Species of the three Longicorn Families Lamiide,

Cerambycide and Prionide, collected by Mr. A. R.

Wattace in the Malay Archipelago. By Francis

P. Pascog, F.L.S., Pres. Ent. Soc.

Tue large private collection of Longicornia formed by Mr.

Wallace during his researches in the Malayan Archipelago having

come into my possession, I have undertaken to describe all the

species which it contains) Mr. W. Wilson Saunders, with his

usual liberality, has offered to contribute towards the expense of

the plates, and the Council of the Society has determined to pub-

lish the descriptions in a continuous form, so that the whole may

be bound up eventually in one volume.

Until I have thoroughly gone through and described the whole

of the collection I can only give an approximate estimate of its

extent. There may probably be something less than a thousand

species ;* upwards of eight hundred of these may be calculated

on as being new to science. With so great a number to be dealt

* T use the word “ species” to embrace “all individuals having such a mutual

resemblance between themselves as leads us to infer a common parentage.” This

definition certainly does not allow us to distinguish absolutely a variety from a

species, but in the absence of positive certainty of the fact, I think it is always as

well to treat as a species any marked departure from the ordinary form, until we

have some proof of its specific identity.

with, it will be desirable to make some remarks on the classification,

prefacing these, however, with a few words on the geographical

distribution of the species and their relations to the same families

belonging to the Indian and Australian faunas. Mr. Wallace him-

self will sum up the results and his views thereon at the conclusion

of the work.

Our acquaintance with the Longicornia of the mainland of

Asia is very imperfect. India, to judge from our collections, has

generally a very meagre insect fauna; but the researches of the

late M. Mouhot lead us to believe that a considerable proportion

of Malayan Archipelago forms are to be found in Cambodia and

Laos, but they probably do not extend in any numbers further

north. The Longicornia of Australia are sufficiently well known

to enable us to institute a comparison which, in its general re-

sults, can only lead us to one opinion, that is, the almost utter

dissimilarity between them and those of New Guinea and, @ fortiori,

of the rest of the Archipelago.* Throughout this work I shall

take every opportunity of contrasting the two, and shall not there-

fore dwell further on the subject at present, except to show, in the

following table of ten of the largest genera of the Wallacean col-

lection, the difference between the Malayan and the congeneric

species, whenever they occur, of the Australian Longicornia.

* Tt is held that the western islands of the Malay Archipelago belong to the

Indian region, and the eastern to the Australian. Mr. Wallace has asserted that

this holds good in every branch of Zoology (Proc. Linn. Soc. 1860, Zool. iv. 172).

* Borneo,” he says, ‘‘ is the counterpart of New Guinea,” and “ the Asiatic and

Australian regions finding in Borneo and New Guinea respectively their highest

development” (ibid, p. 174). On the whole I have not been struck by any

special differences between the western and eastern portions of the Archipelago,

so far as the Longicornia are concerned. Tmesisternus, the only exception I

know, is apparently confined to the eastern portion, but the sub-family of which

it is the type has representatives in Sumatra, Java, Singapore, &c., as well as in

New Caledonia, the New Hebrides, New Zealand, Australia, the Fiji and other

Longicornia Malayana. 3

It is probable that when the species of these genera come to be

examined more carefully for description, a slight discrepancy may

appear, but this may be more or less as regards numbers, and will

not affect our conclusions. On the other hand, it is extremely

probable that the number of Australian species belonging to the

above genera will be increased.

It is unnecessary to go into the history of the classification

of the Longicornia. Dr. Leconte, in the ‘ Journal of the Academy

of Natural Sciences of Philadelphia” (1849-51), was the first to

put forward a really philosophical arrangement of them, but, un-

fortunately, his knowledge was almost entirely confined to the

species found in North America. M. James Thomson, in his

* Kssai d’une Classification de la Famille de Cerambycides” (1860),

has more fully carried out this system,* and at present this is the

only work which treats of the whole of the genera of the Longicorn

families.

If we must consider the Coleoptera to be entitled to no higher

than ordinal rank, it will tend to simplify the classification if we

call the Longicornia a “ sub-order.”’ Following Leconte, we shall

then have the three families of Lamide, Cerambycide and Prionide.

These I propose to divide into “ sub-families.” We then come to

the genera and species. If, for the sake of convenience, other

divisions are required, it seems to me that it will be enough to

constitute ‘ sections,” which may be numbered, but, to avoid con-

fusion, not named. +

Pacific Islands. With regard to the Coleoptera generally, my impression is that

there is a fair admixture of forms from Singapore to New Guinea, without any

remarkable division between them anywhere; but that between the Australian

and Malayan regions (including New Guinea) the difference, on the contrary, is

really something marvellous.

* Some excellent remarks by Mr. Bates on M. Thomson’s work will be found

in the ‘“ Annals and Magazine of Natural History,” ser. 3, viii. 41 et seq.

Mr. Bates thinks the position of the ‘‘ Lepturite” as a group subordinate to the

Cerambycide is untenable, but then le considers that the Distenie should form a

“distinct tribe,” and also that the “ Pseudolepiurite”’ of Thomson * will require

probably the institution of one or more distinct tribes.”

+ The complicated ramifications into tribes, groups, races, cohorts, legions,

branches, divisions, series, sections, and these again into sub-tribes, sub-groups,

&c. &c., to say nothing of the ‘‘stirps” and the ‘ phalanx,’’ whose plurals in

English I cannot venture to determine, all more or less employed in systematic

works, and their application varying with every author, or even in the works of

the same author, are such as to make zoological classification an affair of the

most involved and indefinite character. It is frequently very difficult to ascertain

what are equivalent groups, when we pass from one order or one author to

another; the family of one author, for example, becomes the tribe, or the stirps,

3 Longicornia Malayana.

LAMIIDZ.

Dr. Leconte, taking various characters into account, con-

siders that the Lamiide contain three series of forms; the first,

‘“‘the typical Lamia series,” attains its highest development in

Sternotoma, Ceroplesis, Omacantha, and similar genera—to this he

appends the “Saperdz ;” the second series is represented by the

“‘Dorcadion form;” and the third by the “ Acanthoderes or A’dilis

form.”’ But to these he was compelled to add a fourth series,

** distinguished from all the others by the imperfection of the

anterior acetabula.” ‘These four series were then divided into

seventeen “ groups.”” M. James Thomson (“ Essai,” &c.)

adopts this arrangement almost entirely, but having far larger

materials at his command, he has increased the number of divi-

sions (using this word in a general sense) considerably. We

still count seventeen “ groupes,” but the Dorcadion series con-

taining no ‘‘ groupe” is represented by two ‘ divisions,” a rank

subordinate to the “ groupe.” Of the “ groupes” ten stand alone ;

the remainder embrace eighteen “ divisions,’ and four ‘ sous-

groupes.” So that taking the “ divisions” where there are no

‘‘ oroupes,” and the ‘ groupes” where there are no “ divisions,”

and the ‘‘ sous-groupes” where they occur without the “ divisions,”

we have thirty-four subordinate forms, which we may consider

take the place of the Lecontean “groups.” There are also two

* sous-divisions” in one of the “ groupes:’’ these were probably

intended to be “ divisions ;" if so, then we should have to add one

more, which would bring the whole number of “ groupes,” and

what are nearly equivalent to them, up to thirty-five.

Mr, Bates, in the work above quoted, is satisfied with

dividing the Lamiidz into six sub-tribes, remarking, however,

that two of them might, perhaps, be further divided, and two

or the sub-family, or even the order of another. At one time the tribe precedes

the family, generally it is subordinate to it; the same may be said of the stirps, the

cohort, and the phalanx, &c. The confusion is sometimes increased by the

application 6f names which are completely deceptive, such as Cuculine (a sub-

family of cuckoos) to a group of bces, or indefinite names which are used in

almost every class, such as ‘‘ dquatica” and ‘ Longipedes.” The sub-genus is

another element of confusion. It would be very difficult to say what is the

difference in the value between this and the genus. It offen appears to be‘a sort

of compromise put forward only until the author can make up his mind as to its

real value, and, perhaps, as more likely to escape criticism in its more humble

rank; but it has this inconvenience, that it is tantamount to giving two names,

the sub-genus being adopted in one case and the genus in the other, both being

sometimes used indifferently by the same author: or the sub-genus is inserted

parenthetically, and then we have what amounts to a inomial nomenclature.

Longicornia Malayana. 5

additional sub-tribes instituted. These are the ‘“ Hippopsite”

from the ‘“Onciderite,’” and the ‘ Tapeinite” from the

‘“‘ Saperdite.” The two principal things that strike us in this

arrangement are, first, that no provision has been made for the

Dorcadion forms in any of these sub-tribes,—perhaps, because they

do not occur in the Amazonian fauna,—and the second, the placing

of the * Compsosomite” in the same sub-tribe with the “ Desmi-

phorite,” a position wholly unaccountable from anything I can

gather in the description. Mr. Bates has not, however, over-

stated the case when he says, that “it is a matter of great diffi-

culty, perhaps impossibility, to find constant characters for the

subordinate divisions;” and therefore it must not be expected

that systematists will always agree in their disposition of par-

ticular forms in a group so confessedly difficult as the Lon-

gicornia.

This difficulty arises from the great diversity of forms, and

the gradual modifications of even the most important organs in

nearly connected species, so that if we were to insist strictly on

definitions, we should add almost indefinitely to the genera, and

many of these again would have to be raised to the rank of sub-

families. It frequently happens that we can only judge of the

value of a character when we are able to follow it up into allied

forms: an apparently excellent generic diagnosis, drawn from

a single isolated species, may break down altogether when

there are half-a-dozen to be dealt with; and in the case of

higher groups than genera, we shall often find beyond its typical

members a tendency only to the character which more than any

other affects that particular group, or in other words the cha-

racter becomes modified, or is lost altogether. In each of the

sub-families of the Longicornia, I have noticed that there is

generally one preeminent character, and other characters, that

elsewhere were of primary importance, then become of secondary,

or, perhaps, only of specific value. ‘The absence of humeral

angles and, consequently, of wings in the Doreadion group, for

instance, being of this special importance, we find other characters

so Salhardindtc as almost to startle us at meeting the most es

site of them in apparently nearly allied species.

In the arrangement of my collection, I have come to the ~

conclusion, that there are at least twenty-four types among the

Lamiidee which can be clearly demonstrated. It is true, that in

no case, after we have referred the various genera to their respec-

tive types, can any of them be distinguished by any absolute,

much less by any series of characters, but by an examination of

6 Longicornia Malayana.

each of these, as given in the definitions below, the tendency to

gravitate to its proper type will be generally manifest in the com-

bination of two or more of the characters, and the absence of

others, in each genus. In cannot be denied, however, that there

are a number of forms, which, place them as we may, will always

be more or less anomalous members of the group to which they

may be referred. And it may be added, that there are many

genera whose location will depend in a great degree on the im-

portance which some particular character may be thought to

possess, and this importance may be modified at any time by the

discovery of intermediate forms, so that we may be led to detect

an affinity between genera, where previously we had no suspicions

of any. Systematists, perhaps, allow themselves to be too much

influenced by aberrant forms, and too readily disposed to regard

them as types of distinct groups.

It is not to be supposed that these sub- faniilies naturally

follow each other exactly in the order they are placed below,

but it will be readily understood that it is impossible to arrange

them satisfactorily in a linear series. Saperdinz, for instance,

might follow Niphoninee, Dorcadioninze Lamiinz, &c., but then

this would break in upon other affinities of, perhaps, more im-

portance. Tapeininz is placed at the end because it is the most

anomalous of all the sub-families; at the same time the Tmesis-

terninze, being the transition group to the Cerambycidz, might

equally well terminate the series of the Lamiide. It is not im-

probable that some of the sub-families may be further divided

with advantage—Anisocerus and allied genera from Acrocinine,

for instance ;—and it may be doubted if the Lamiinee can be main-

tained in their present entirety, but we have none of the former

and very few of the latter in this collection.

are bracketed.

ACANTHOCININE.

The well-known Acanthocinus edilis and Leiopus nebulosus afford

good examples of the more usual forms of this sub-family, which

finds its greatest development in the tropical regions of the new

world. The Acanthocinine are distinguished from both Acantho-

dering and Colobotheine (neither of which have exponents in this

collection) by the short, often transverse, face; from the former

also by the slender tarsi and antennz, the elongate scape, and less

robust body; and from the latter by the body more or less de-

pressed, the prothorax toothed or angulated at the side, as well as

by the scape and tarsi, which do not, however, afford quite so

marked a contrast as they do with the Acanthoderine. Besides

these characters, the Acanthocinine have generally long and seta-

ceous antenne, arising from two diverging tubers, which have an

impressed line between them, and the second joint is almost in-

variably two or three times longer than broad, never transverse ;

the eyes are reniform, often occupying a considerable portion of the

head; the mandibles are feeble, and, when closed, generally pretty

well covered by the lip; the elytra are frequently truncate or

spinous at the apex; the anterior acetabula are entire, or only

slightly angulated ; the anterior and intermediate cox are globose

and approximate at the base, with the pro- and meso-sterna simple

and declivous; the femora are clavate; the fore-legs are never

elongate in the males, although the posterior are occasionally, and

their tarsi are scarcely dilated and never fringed; the claw-joint

varies in size, generally, however, small; the three intermediate

segments of the abdomen are always the shortest; the colour is

mostly ashy or greyish varied with brown, and there are often

setose hairs scattered among the pubescence. Many of the females

have lengthened ovipositors.

Fourteen genera are in the collection, most of them very dis-

tinct; none of them, so far as I am aware, occur either on the

mainland of Asia or in Australia.

Thinly pubescent, dark greyish shading into white on each side

of the prothorax and on the posterior half of the elytra, where

also there is a pure white mark bent at an acute angle on each

side towards the apex. Head narrower than the prothorax,

slightly dilated below the eyes, the lip and epistome narrow ;

prothorax transverse, strongly spined at the sides, the anterior

and posterior borders of equal breadth ; scutellum rounded behind ;

elytra broader than the prothorax, depressed in the middle or

somewhat concave, coarsely punctured, a line of small spines near

the suture and several smaller ones at the shoulder, one also

rather larger than the rest between the shoulder and scutellum,

the apex truncate at the suture, then broadly emarginate ex-

ternally, and ending in a long acute spine; body beneath with a

pale greyish pubescence; legs obscurely annulated with greyish

and white ; antenne about three and a half times as long as the

patch. Head scarcely narrower than the prothorax, which is very

little broader behind and without a tooth at the side; scutellum

not transverse, rounded behind; elytra oblong, rather narrow,

with several rows of depressed black setz, outer angle of the apex

not spinous; body beneath, legs and antenne dull fulvous, with

obscure brownish patches and a thin greyish pubescence ; antennze

about twice and a half as long as the body.

Length 33 lines.

This species in some respects approaches Chydeopsis, but the

more depressed body, style of coloration and form of the protibiz

are more characteristic of Driopea. ‘The amount of black varies ;

on the upper portion of the elytra the patches are sometimes

more or less confluent.

a band of ashy posteriorly, followed by another band of brown, the

apex ashy. Eyes moderately large and prominent; head and

prothorax nearly equal in breadth, the sides of the latter nearly

parallel or only very slightly rounded; scutellum scutiform;

elytra broadest at the base, much wider than the prothorax, with

several lines of large coarse punctures ; body beneath covered

with a fine greyish pile; antenne and legs brownish, distal half

of the posterior and intermediate tibie ciliated; antennz nearly

three times as long as the body.

The type of this genus is nearly allied to Ostedes, to which

I had formerly referred it. The form of the prothorax, however,

is so different as to necessitate its separation as a distinct group.

Hab.—Batchian, Amboyna, Morty, Dorey.

Finely pubescent, greyish varied with brown, the two principal

patches of this colour being on the sides of the elytra. Head

somewhat wider than the anterior margin of the_prothorax, the

Jatter a little longer than wide, with two nearly obsolete tubercles

in front, anteriorly and posteriorly transversely sulcated; scu-

tellum rounded behind; elytra narrow, the basal half sparingly

punctured, a prominent, strongly-recurved spine on each towards

but at some distance from the base, a few minute spines also at

the base and sides ; legs dark brown, more or Jess of the femora

and basal half of the tibize reddish; body beneath reddish-brown;

antennz more than half as long again as the body, reddish varied

with brown.

A specimen from Ceram, much larger than the others, has also

a somewhat broader prothorax. It may possibly be distinct.

Polimeta simplex.

Closely resembles the last, but there is no spine on the elytra,

which are also less attenuated towards the apex, the sides, in

other words, being more parallel ; the scutellum is slightly pointed,

and the anterior border of the prothorax is less strongly sulcated.

Finely pubescent, with a few scattered seta, especially between

the eyes, pale ashy or greyish with patches of brown, sometimes

with a few spots only. Head broader than the anterior border of

the prothorax, slightly exserted; eyes rather large, prominent,

sub-approximate on the vertex; prothorax of the male nearly

twice as long as broad, with a very prominent angle rather beyond

the middle, the disc with four spreading tubercles; scutellum

rounded behind; elytra irregularly punctured, gradually dimi-

mesial crest, tipped with a few sete, the largest patches, when

they occur, at the side behind the middle; body beneath brown,

with a greyish pile; antennee and legs ringed with greyish and

brown, the former in both sexes about a third as long again as the

body.

The varieties of this species, as might be expected from its

extended .range, are numerous, but they are all too trifling for

description, differing principally in the amount of coloration.

Those from Morty are the darkest. The female has the pro-

thorax scarcely longer than broad, and the angle is nearly in the

middle.

rather narrower below the eyes, emarginate at the apex, the

epistome and lip very short; prothorax somewhat oblong, slightly

rounded at the sides; elytra gradually tapering from the base to

There is no genus that approximates to this in the present

in the tarsi, and in the antenne. The coloration is much in the

style of some of the Clyti.

Corpus pilosum.

From Zgocidnus this genus differs in its narrower head, stouter

antenne, and shortly fusiform scape; it is also a more robust form.

Clodia has a sub-basal thoracic spine, and the head more deeply

inserted in the thorax. The species, five in number, are very

homogeneous; their colour varies from light to dark brown, and

is modified by a greyish pubescence, mixed with short, scattered

erect hairs; the elytra sprinkled or spotted with white or ashy,

and in all the head, prothorax, and elytra are strongly punctured ;

on the latter the punctures are arranged in irregular lines. The

apex of the elytra is either rounded or truncate, but in this respect

there is a certain gradation between the species.

narrower than the prothorax, even at the apex, the vertex con-

siderably raised above the eyes; prothorax twice as broad as

long, the disc between the tubercles with coarse, closely-set punc-

tures, which are pitchy-brown internally, giving that part of the

prothorax a much darker appearance than the sides, which are

more densely pubescent; scutellum dark brown, very transverse,

and contracted at the base; elytra very much broader than the

prothorax, especially at the base, coarsely punctured in somewhat

irregular lines, the basal ridge very short, dark brown, behind

this two oblique slightly elevated stripes of the same colour, one

in the middle, the other towards the apex, the side bent down at

a right angle, forming, from the shoulder to near half the length

of the elytra, a sharp well-defined ridge; posterior margin and

apex fringed with longish, curved, white hairs; body beneath

and legs covered with a greyish pile, the tibiz also fringed with

long hairs; antennz half as long again as the body, very pale,

pile pretty equally distributed over the surface ; elytra scarcely

dilated posteriorly, as in the two preceding species, with very

coarse punctures arranged in irregular rows, the ridge at the base

very slightly elevated and extending to about the middle of the

The only species of this genus has the aspect of a small

Monochamus. The antennz, however, distant at the base, the short

scape and clavate femora, among other characters, separate it

from that group. The equal or nearly equal length of all the

tarsi, and the peculiar form of. the eye, will, one or the other,

distinguish it from the other genera of this sub-family. The

anterior acetabula are angulated externally.

Femora clavata, tibie anticze curvate, tarsi subbreves, arti-

culo primo secundo equali.

In the habit, approximate or subapproximate antennz, and

the greater length of the terminal joint, this genus resembles

Monochamus, Serv., but the clavate femora and short subpyriform

scape exclude it from any connexion with that group. In the

character of the terminal joint of the antenne and in habit

Aischopalea agrees with Acalolepta. The eyes in both are

remarkable ; the upper lobe terminates behind the antennary tuber

and not above it, so that when these organs are thrown back

nothing of the eyes is seen on the vertex. The scape is pyriform,

but owing to a greater contraction on the upper side it has a sort

of oblique appearance. The head, including the eyes, is rather

roundish in front, but a little pinched up below the tubers, and is

about as broad as the prothorax ; this latter organ is considerably

narrower than the elytra in all except . laticollis.

with a coarse greyish pubescence, interrupted over the punctures,

these are smaller than in 4. tomentosa, but are equally crowded,

and the prothorax, including the angles, is nearly as wide as are the

elytra at the base, and is, perhaps, a trifle broader than it is long ;

antenne rather more than twice as long as the body.

26 Longicornia Malayana.

EXocEeNTRINE.

This sub-family is very nearly allied to the last ; indeed, latterly,

authors have not made any distinction between them. M. Mulsant,

who, first proposed the sub-family or “ Branche,” as he termed it,

under the name of “ Pogonochéraires,” only mentioned the three

genera Pogonocherus, Exocentrus and Stenidea. M.Thomson places

the first and last of these in his sixth “ Groupe Saperdite,” Exocen-

trus taking its place in the second “ Groupe Acanthocinite,” with

two or three other genera which I refer to this sub-family. M.

Thomson is probably right in the position he assigns to Stenidea,

but I think Pogonocherus cannot be put far from Exocentrus, and

as the latter is the most typical of the two it would be more

appropriate to take its name for the sub-family.

The Exocentrine have the face convex or rounded, generally

short and transverse; the antennary tubers pretty far apart, so

as only to leave the usual mesial line, with very little tendency to

depression between them: the eyes are small or of moderate size,

deeply and widely emarginate; the mandibles rather feeble and

without teeth, and the palpi are pointed. The antennz are variable,

but they are never so long as in many of the preceding sub-family ;

very often the joints are short and thick, or even tumid, almost

always with a fringe of stiffish hairs beneath, or the whole of those

organs is more or less hairy. The prothorax is generally armed at

the side with a short spine, which is often placed near the base; in

some genera this part shows a remarkable tendency to arching or

curving upwards above the level of the elytra, and the disc is

occasionally armed with two spines. The elytra are more or less

oblong, with the apex entire, at least so far as the species of this

collection are concerned. The legs are of moderate length, the

femora always clavate, the intermediate tibia emarginate, and the

tarsi never elongate; the anterior coxee are large and standing

well out of their acetabula, and these latter are either entire or

angulated. The species are all of small size, rather depressed and

very often clothed with long erect hairs, which are sometimes stiff

enough to be called “ set@.” They are found in all parts of the

the world, and are represented in Australia by the genera Pen-

tacosmia, Newm., and Ameipsis, Pase. (each of one species only),

and Exocentrus erineus, Pasc.; in New Zealand, by the Lamia crista,

Fab.; but there can be no doubt that these numbers will be con-

siderably increased when the insects of those countries shall be

better known. In the present collection we have twenty-two

genera and and forty-nine species.

The differences between the two common European forms of

this genus (LZ. balteatus and E. adspersus) render it difficult to

draw up a very decided diagnosis of it, yet at the same time no

one doubts that they are congeneric. The species described

below, except EZ. meerens, in the form of the prothorax are most

allied to E. adspersus. I have formed a section apart of

E. merens, as the small prothorax, not broader than the head,

although transverse as in the others, appears to indicate’ some-

thing beyond a specific difference, but, on the other hand, the

prothorax of E. balteatus seems pretty nearly intermediate.

It is with some hesitation that I propose to separate the species

described below from EF xocentrus, which, having a wide geo-

graphical range, may be expected to present a considerable

amount of variation. However, the narrower head, the more

slender antenne, with the greater length of the third and fourth

joints when’compared with the scape, the absence of setz, and a

difference of coloration, would seem, taken together, sufficiently

distinctive characters, were it not that there are indications that

the most important of them, z.e. those of the antennae, may prove

to be too variable for generic use. Thus in S. melanotis, for in-

stance, the fourth joint is considerably shorter than the third,

while it is longer in S. mutatus, and about equal in S. suffusus.

This shading away of characters is, unfortunately for the syste-

matist, more the rule than the exception in the Longicorn families,

The long and slender antenne shut this genus out from the

genuine Lxocentri, with which I had formerly arranged it. It

may be remarked that the femora are more clavate, and the

slender basal portion so lengthened that it is seen from above.

The single species upon which the genus is founded is remarkable

for the long hooked spine of the thorax, which is also slightly

bifid at the point of its greatest convexity.

two lines and three quarters ; the punctures on the head and thorax

are minute and very closely placed, those on the elytra are coarser

and have to a certain extent a linear arrangement,

The unusual length of the third and fourth antennal joints

(bringing the fifth to the apex of the elytra) is the principal

character of this genus, which, in other respects, approaches

Aigocidnus (post, p. 40), except that the pubescence is opaque

and not silvery. The two species differ principally in colour, but

the scutellum of 1. marmorea is very decidedly transverse.

Exocentrus (ante, p. 28) bear a marked resemblance to Agocidnus,

but they have less clavate femora and stouter antenne. The

species of this genus are clothed with a sort of silvery-greyish

pubescence, having, however, at the side of each elytron, near

the middle, a large bare patch; the head and prothorax are very

minutely and closely punctured, but, except in 4. juvencus, the

punctures are tolerably well marked on the elytra,

The prothorax is shorter, or rather, perhaps, proportionally

narrower, than in the two former species, and in the most perfect

of my specimens there is a decided, although interrupted, median

line on that part; the elytra are perhaps uniformly grey, but, from

abrasion, there are irregular dashes of reddish-brown in the above

This genus offers the singular character of a deeply emarginate

posterior tibia: this is the more marked, as the tibia just above

the emargination forms a very strong angle or tooth; the inter-

mediate tibiz are also deeply emarginate, The genus is also

peculiarly distinct in its ribbed elytra, or rather the intervals

between the striz form elevated lines, which at the base are par-

ticularly prominent.

This is one of those genera which, from the shortness of the

legs and the thickness of the antenne, seem to connect the

Apomecynine with the Exocentrine. In fact it strongly resembles

the North American Eupogonius, which, on account of its entire

mesotibiz, we refer to the former sub-family; on the other hand,

Athylia has angulated anterior acetabula; this character is, how-

ever, as we have already seen, not a very reliable one. On the

whole, taking also into consideration the large and prominent

anterior coxz, and the undoubted connexion that exists between

this genus and many other genera of the sub-family, we have little

hesitation in referring it here.

This is the first of those remarkable genera, of which there are

antennal joint which I have just sought to describe by the term

44 Longicornia Malayana.

* ventricose,” that is, a joint gradually swelling out to the middle,

but only on one side. As usual, there are gradations even in the

same antenna, and the form also appears to pass into the obconical

joint we see in Lb@ides. The type of this genus bears a strong

general resemblance to Cuallia, the members of which group are

also found to imitate various species of the Gallerucide. The

thoracic spine is well marked, and directed obliquely backwards ;

the prothorax behind it curving inwards to the base. The pro-

tibize are slightly curved, a character which finds its greatest deve-

lopment in kbeides. The anterior acetabula are strongly angulated

in this genus, especially in C. tristis.

So far we have been dealing with genera with simple elytra; in

this and Axinyllium these organs have a curved elevated spine at

the base of each, and behind the spines the elytra are more or less

depressed. This depression attains its maximum in the genus

Oloessa, a remarkable form, which, as the most aberrant genus of

the group, I have placed at the end. In the three genera there

is also an arching, more or less, of the prothorax and head; this

is the most decided in Oloessa. ‘These peculiarities would almost

seem to indicate another type of form, but from what I have said

above, it will be seen how graduated are these modifications, and

how difficult it is to use them satisfactorily as a means of classifi-

cation, In G. hamatus the anterior acetabula are entire.

The remarkable thickness of the antennz in this genus, especially

the thickest of the antennal joints. On the other hand, the last

joint is very small, and in three of the species, if the character be

not a sexual one, disappears altogether, the tenth joint being

then nearly as small as the eleventh is in the other species. The

anterior tibize are short and curiously bowed, and this is sometimes

the case also with the intermediate and posterior, only in a less

degree. As usual in this sub-family the pubescence is very short

and much thinner on, or very nearly absent from, the head and

prothorax ; and the punctuation on those parts is scarcely visible,

This genus has quite the habit of Ebeides, from which I

thought at one time that it would be unnecessary to separate it,

but the peculiar structure of the antennz of this genus, and the

different form of the scape, preclude a sufficiently clear definition

of the two groups if they were kept together. The compara-

tively short thick scape, contracted at the apex, will distinguish

Dyemus from Enispia (ante, p. 50), from which it also differs in

habit and coloration.

Corpus breviter setosum.

In the form and length of the scape this genus is almost ex-

ceptional in its sub-family, and it is quite so in its divided eyes.

Tt has, however, the arched thorax of Ebcides and the elytra of

Gyaritus ; and what is more remarkable, it is so closely allied to

the North American genus Cyrtinus, Lec.* (Clytus pygmaeus,

Hald.), that except in the antenne and eyes I scarcely see how

it differs. In both the femora are extremely attenuated at the

base, then suddenly dilated, especially on the upper edge. The

species upon which the genus is founded is one of the smallest of

the Lamiide, scarcely exceeding a line in length.

* Dr. Leconte places this genus with the Doreadions! Three very anomalous

genera, Microplia, Serv. (Leptoplia, Dej.), Omosarotes, Pasc., and Scopadus, Pasc.

(all South American) should also, I think, be placed near the above, The first

of these has the long scape, attenuated at the base, and gradually enlarging up-

wards, of Oloessa; the last two have the “‘ Cyrtinine”’ profile in perfection, while

in Microplia it is only just beginning to develope itself, as in the case of Gyaritus,

but after another type.

NIPHONINE.

The principal characters of this sub-family, which very nearly

corresponds with the “‘ groupe Onciderite”’ of M. J, Thomson,+} are

the large claw-joint and the ovate or shortly clavate scape. This

last character has not hitherto been noticed, I believe, but it

separates this sub-family from the Mesosine, which have a long

cylindrical scape. The greater part of the genera, although fre-

quently composed individually of what may be termed “ fine”’

species, are generally of a rather commonplace appearance, and

they are, as might be expected, very difficult to limit. -

The Niphonine have mostly a moderate-sized ovate head, more

or less transverse or subquadrate anteriorly,—that is, from the

vertex to the line of the insertion of the epistome,—or it is very

large, flat or rounded in front, as in d4bryna, Oncideres,t and other

genera. ‘The antennary tubers commence near the eye, or some-

times arise near the mesial line when they become approximate

at the base; they are cornuted in the males of Oncideres. The

eyes are almost invariably of moderate size and deeply emarginate.

* This is not correctly represented in the profile figure.

t Of the ‘ Essai,’’ not of the ‘* Syst. Cerambyc.”

t This genus, although a very natural one, is most variable in its characters.

Longicornia Malayana. 57

The antenne vary from two or three times the length of, to a

little shorter than the body, the terminal joint is frequently hooked

at the point, but the scape is always short, or comparatively so,

and ovate or slightly clavate, except in some species of Oncideres.

The prothorax is usually subtransverse, unarmed at the sides,

but having instead one or frequently two short tuberculiform teeth

near its anterior border. The elytra are oblong or ovate, with a

tendency to develope into crests or elevated lines at the base, or

to throw out little granules, which are almost invariably black

and glossy. The legs are of moderate length (except in many

cases the fore-legs of the males), and robust; the thighs more or

less clavate, never linear. The tarsi are nearly all of equal length,

more or less trigonate, with the claw-joint as long as the three

basal taken together. -The anterior coxz of the males are often

armed with a recurved spine, occasionally of a formidable length,

as in Ischioplites metutus and Xiphotheata Saunders. The pro-

sternum is invariably elevated to a level with the coxe, except in

Oncideres, and this is often met by a corresponding elevation of

the mesosternum, so that the power of the insect in bending is

considerably reduced. The three intermediate abdominal segments

are the shortest; in a few species, however, the second segment is

of greater length, and is then covered, more or less, with a semi-

circular patch of very densely set erect hairs.

In this great sub-family Europe is represented by only a single

species (Niphona picticornis). Oncideres, numerous in species,

and other genera, abound in South America. Africa yields Hecyra,

Dichostates, Diastocera, and a few other genera not containing

many species. In Australia we have numerous species of Sym-

phyletes, Rhytiphora, Penthea, &c. From Asia we know of no

genus peculiar to it, and very few species. In the Wallacean

Collection we find eighteen genera and fifty-seven species.

The characters that have been used in the following table are

mostly of a secondary nature, but they are the most obvious so

far as the species treated of here are concerned.

A broader and more robust form than Niphona, the prothorax

more convex and even, the sterna more produced, the fore-legs

of the males elongate, and their femora larger than those of the

intermediate and posterior legs. From Aziothea it differs in the

unbroken surface of the prothorax and elytra. The species, and

even individuals, vary greatly in size, and owing to the mono-

tonous repetitions of nearly the same sombre and indistinct colours,

are difficult to determine as well as to describe.

The species comprised in this genus have a narrower and less

bulky figure than most of the other species belonging to this

sub-family. This is principally owing to the more trigonate

elytra, which are also more depressed at the base, and without

any carinz or crests. The longitudinal line, more or less elevated,

on the prothorax is smooth and without pubescence, and has

therefore a more marked appearance, which with the subtrigonate

elytra contribute to give the genus a character distinct from its

colour at the base of the posterior margin of the prothorax in all

the species; there is a little depressed point on each side of the

seutellum, free from pubescence, but in one individual of 4.

jubata there is no trace of this point.

The strongly marked mesial ridge on the prothorax will

distinguish this genus from Axiothea (post, p. 72), to which it is

nearly allied, but from which it also differs in the form of its pro-

thorax, elytra, protibize, and the presence of spines on the anterior

coxe of the males. I have been very much puzzled with the first

two species. No two congeneric forms can apparently be more

distinct, but then intervening forms occur, which, with the excep-

tion of the mesial ridge (and not always then), offer scarcely any

definite characters. Even the tooth on the anterior femora is absent

in one specimen which there can be no hesitation in placing with

2. carinicollis; and there are others where the description given

for that species has only a partial application, varying more or less

in each: these remarks are purposely confined to the males.

Nevertheless (and subject to this explanation) I think it will be

better to furnish the two forms with distinctive appellations. They

appear to be very common where they occur, and the two will

doubtless be found very difficult to separate. The colour varies

from grey to pale ashy, which is more or less extended at the ex-

pense of the brown, and this sometimes, at least in E. carinicollis,

I have already (p. 70) pointed out in what respects this genus

differs from Escharodes, its nearest ally. The first described species

differs very much in the depth of its colours, the dark brown

being replaced by light brown, and this again by grey, the median

patch only showing feebly. With regard to A. distincta, its

colour is also variable, but it may be readily distinguished from

A. strenua by the smaller and more scattered granules. Axiothea

wnvida is characterized by a well-marked basal crest on each

elytron; in the first two species it is little more than a raised

line. This also appears to be very variable as to colour.

Four coarse uncouth-looking species comprising this genus are

in the collection. In addition to the diagnoses that may be

gathered from the table (ante, p. 58), the absence of armature at

the sides of the prothorax will serve at once to distinguish it from

Escharodes and Axiothea, its nearest allies. The species of Sotades

have all a black shining derm, closely covered with short flat hairs

or scales of various shades of grey, with the usual irregular oblique

patch or band just behind the middle, which characterizes so many

of this sub-family. It may be observed, however, that these scales

appear very liable to be rubbed off. From amongst this pubes-

cence numerous small black shining granules crop up.

It will be seen from the above how difficult it is to formulate,

with any degree of precision, the characters of a large longicorn

genus. I have thirty-six species now before me, all Australian,

except the three described below, each of which is very distinct

or even isolated, as is the case with some others which have been

referred to the genus. It is, however, to be observed that Sym-

phyletes is a very heterogeneous genus, but it would only retain

S. nodosus, Newm., the type, if it were to be divided, and then

seven or eight more genera would have to be formed. At the

same time Penthea and Rhyliphora are scarcely to be distin-

guished from Symphyletes as it stands at present. The question

is, does this group form only a single genus of highly indi-

vidualised species, or is it a collection of many genera? I believe

if the same principles are applied as to other genera, especially of

European Coleoptera, that the question must be answered in the

second alternative.

The type of this genus is Penthea conferta, Pasc.; but although

from the true Penthee it is different in habit and coloration,

I can find no primary character by which to separate it tech-

nically, except the toothed prosternum as contrasted with the

rounded prosternum of Penthea. As secondary characters we

have the prothorax broader at the base than at the apex, and

the elytra entirely destitute of the elevated lines that distin-

guish every species of Penthea, P. granulosa, Guérin, alone ex-

cepted, but which is probably not a true Penthea. The three

species described below are tolerably homogeneous, except that

80 Longicornia Malayana.

E. agnata departs slightly from the others in the narrower and

more irregular prothorax. The head in all is considerably nar-

rower than the prothorax, which, again, is also, notwithstanding

its breadth at the base, much narrower than the elytra.

The following, the only species of lara in Mr. Wallace’s Col-

lection, was published by me some time ago under the name of

Niphona arrogans; but there are several others from the Conti-

nent, such as N. Ferdinandi, N. cylindracea, N. pannosa, N.

eacisa, &c. The first of these has been recently separated from

Niphona by M. James Thomson under the name here adopted,

and the others just mentioned are undoubtedly congeneric. In

both genera the tibize of the posterior and intermediate legs are

shorter than their respective tarsi. M. Mulsant attributes to

Niphona 12-jointed antennz, the last almost rudimentary ; but

I have not been able to realize this character.

When the single species composing this genus was published,

I referred it to Symphyletes ; it has, however, a habit different

from any of the species of that genus, and the presence of a strong

tooth on the anterior tibiae of the male is a sufficient justification

for separating it. The spine on the anterior coxz is unusually

long, and of course is not present in the female.

ABRYNA.

Abryna, Newman, The Entom. i. 289.

Caput antice subtransversum, Jatissimum, medio carinatum,

Mr. Newman founded this genus on a Manilla longicorn,

the Abryna ceenosa; to this he successively added four other

species, which he referred to the same genus. Three of these I

have since proposed to separate under the generic name of

Aprophata (Journ. of Entom. i. 342), which, from their small

humeral angles, seem to approach the Dorcadionine. The Baron

de Paiva has also published a fine Cambodian species under the

name of Abryna Regis Petri,* and with those described below the

against double specific names, such as Niphona Regis Ferdinandi and Abryna

recently published by Professor Westwood, one (Abryna Semperi,

Trans. Ent. Soc. ser. 3, i. 630) evidently belongs to Aprophata.

Dark brown, almost inclining to olive, and somewhat glossy,

with a very sparse greyish pubescence, except where the spots and

patches occur; head large and very broad, especially below the

eyes; epistome and lip elongate, pale yellowish; mandibles and

palpi pitchy; prothorax rather narrower than the head (not

broader, as in 4, Petri), subtransverse, with the pubescence much

scattered, the upper tooth forming more of an angle from the side

(less of a tubercle than in 4. Petri); scutellum rounded behind ;

elytra rather irregularly punctured, the pubescence condensed on

parts to form spots and patches, the former are scattered in the

intervals of the patches; these, as in the other species, form two

irregular bands, interrupted, however, at the suture, and a few

confluent somewhat indefin:te blotches towards the apex, there is

also a still more indefinite condensation at the base, the apex

truncate; body beneath with a thin ocbraceous-greyish pile,

especially on the abdomen; legs spotted with greyish ; antenne,

except at the base, almost glabrous.

short, covered with grey hairs; mandibles black; palpi dark

brown; prothorax about the breadth of the head, subtransverse,

covered with a dull greyish pile; scutellum small, rounded

behind ; elytra irregularly punctured, generally two or three pale

hairs at the bottom of each puncture, with two broad wavy bands

nomenclature should be resisted, and the names be either ignored altogether, or

modified by limitation to the least objectionable of the two words intended to

form the specific name.

The species of this genus are more robust than Niphona and

differ in several important particulars, especially in the prosternum

having its anterior portion perpendicular. Niphona thoracica, Vh.,

and Niphona suffusa, Pasc., must be referred to it, although the

former differs in its somewhat cylindrical scape; it is also pecu-

liar for a singular wedge-shaped cleft in the prothorax. Meechotypa

suffusa (with which M, arida, Thoms. |. ¢., is probably identical)

has three beautiful rose-coloured lines on each elytron, the under

parts are also tinged with the same colour, and the two basal

joints of the anterior tarsi have a pinkish hue.

The fore tibize of the males toothed on the inner edge, a pecu-

liarity also found in Xiphotheata, and the granuliferous prothorax,

will distinguish this genus, which has also a peculiar aspect owing

in part to the elevated lines on the elytra, and the more slender

legs and antennee. From Escharodes (ante, p. 70) it differs at once

in its rounded mesosternum.

The form of the scape, in conjunction with the irregular pro-

distinguish this genus. The table (ante, p. 58) will show how it

differs from Escharodes, lara and Exarrhenus, to any one of

which it might be referred except for certain characters, to which

it is necessary to adhere if we would differentiate these genera

satisfactorily. In habit Menyllus most closely resembles the

Australian genus Platyomopsis, which, however, inter alia, has the

antennze of Symphyletes.

I have already pointed out the distinction between this genus

and the last. I may add, that the shorter elytra of Mispila, and

therefore of its abdomen, give a backward position to the hind

legs that completely alters its habit as contrasted with Dryusa.

The species described below are perfectly homogeneous in their

appearance. They are all covered with a greyish pile, and suffi-

ciently sparse to allow the derm to mingle its proper hue with

it. Besides the pile the whole upper surface and legs are fur-

nished with numerous slender erect hairs, each arising from the

base of a puncture, dark brown on the former except at the sides,

very pale grey on the latter and sides of the elytra. On the

antenne, except the three basal joints, these hairs are confined to

the lower side, there forming the usual fringe. The punctures on

the elytra are in reality principally arranged in rows, except near

the scutellum; they have somewhat an oblique direction, and are

not very obvious ; the punctures are of moderate size and strongly

marked. The irregular flexuous spots or broken lines that occur

on the elytra appear to be occasioned chiefly by the closer conden-

sation of the pile. On the prothorax, the posterior transverse

sulcation is well marked, the anterior is much less, and is at

a considerable distance from the apex.

This is the most striking of all the genera of Niphonina, and it

is the more remarkable inasmuch as the female has an unusually

stout and lengthened tooth on the side of the prothorax anteriorly,

while in the male there is no appearance whatever of any such

armature. On the other hand, the male has a very powerful

spine on the anterior coxa, as well as a sharp tooth on the pro-

tibia; these are denied to the females. I have dedicated the only

species at present known to W. Wilson Saunders, Esq., F.R.S.,

MEsosIn&.

With few exceptions this sub-family will be found to be iden-

tical with the 17th “groupe Mesosite” of M. J. Thomson’s

“Systema Cerambycidarum.” It is principally characterised by

its long and more or less cylindrical scape, generally arising from

a very short or nearly obsolete tuber, which is rarely approximate

to its fellow.

Many of the members of this sub-family are among the hand-

somest of the Lamide of the old world. They are in fact con-

Longicornia Malayana. 95

fined to Asia and Africa, with the exception of three European

species of Mesosa* (one of which occurs in England). None

have hitherto been detected in Australia.f Of the twenty-one

genera included in the Wallacean Collection, ten also occur on

the mainland of Asia, and besides these a few more have been

very recently described by M. Thomson, principally derived

from the extensive collections made by the Comte de Castelnau

in Malacca. Three species are known to me from North China,

but from the English possessions in India I have never seen a

specimen; that country is, however, nearly a derra incognita to

the entomologist.

The head in the Mesosine is always more or less quadrate, the

front generally ample, never spreading out below the eyes, the

antennary tubers small, and, with one or two exceptions, widely

apart; the eyes small or only of moderate size, and deeply and

widely emarginate ; the antennz are more or less slender, but the

scape is always long and cylindrical or occasionally slightly clavi-

form, produced and having a scar-like section at the apex; many

of the genera have their antenne more or less pilose, or tufted.

The prothorax is even, rarely irregular, a few genera only having

a short tooth at the side.t In the majority of the species the

elytra are also perfectly even, but in some there is a tendency to

the production of elevated lines, and in one genus of basal crests

(£sopida). The legs are, on the whole, of moderate length, the

anterior being almost invariably the longest, especially in the

males; the femora are stout, thickest in the middle, not clavate,

the tibize are always considerably longer than their tarsi; the tarsi

are short, of equal size, except that the anterior are sometimes

dilated, the three basal joints together not often exceeding the

claw-joint in length. The anterior coxe are large and globose,

never armed, and their acetabula are narrowly angulated ex-

ternally ; the prosternum is generally raised to a level with the

coxe; the mesosternum is also elevated with few exceptions, and

often produced or toothed anteriorly.

The number of species in the collection is upwards of sixty,§

distributed into the twenty-one genera tabulated below.

* Dr. Leconte, however, describes a Mesosa from California. This forms the

genus Synaphe, of M. James Thomson.

+ The genus Meton, placed in tbis sub-family by M. Thomson, is, from its

short scape, approximate antennary tubers, and longer and unequal tarsi, rather,

I think, to be referred to the Monochamina.

t In Agelasta, a very natural genus, some of the species have a very decided

lateral tooth, in the majority there is no trace of it whatever.

§ In the genus Cacia we have three or four forms, of which it is extremely

difficult to say whether they should be treated as species or as varieties.

Three fine and closely allied species at present compose this

genus. It is remarkable for its apparently almost glabrous sur-

face, except that the posterior portion of the elytra is clothed with

a delicate pubescence gradually increasing in density towards the

apex. The genus is nearly allied to Agelasta, but the body ts

depressed, the antennz are more attenuated, and the prothorax

has a different outline.

In the table (ante, p. 96) the mesosternum is stated to be de-

pressed, but this is not exactly correct; it is, however, quite

different from the elevated, broad and flattened mesosternum of

Aimocia. Jn fact it is rather declivous than depressed (more or

less so according to the species), is much narrower, and has a

litle oblong tooth, or rather carina, in the middle. The type (4.

three are closely allied; a larger series of specimens might possibly

show that one of them—A. simulans—is only a local aie -species.

Mr. Newman, in characterising this genus, describes the an-

tennz as being distant at the base, the head between them sul-

eated. The latter character is due to the strongly developed

antennary tubers, closely approximate at their origin, but rising

obliquely, and forming a very deep and angular depression as they

diverge. It is, however, incorrect~to say that the antenne are

distant at the base, except in the sense that they are not con-

tiguous ; they are in fact much more approximate than in almost

any other genus of the sub-family. In both sexes there is a

strong tooth, scarcely long enough for a spine, at the apex of the

third joint, and the antenne, instead of becoming gradually more

attenuated towards the tip, have the last four or five joints nearly

linear, or in the males of some species (P. papulosus, P. vicarius,

&c.) even slightly thickened, especially the terminal joint. The

elytra are almost perfectly flat above, but bent suddenly down

so as to form an angle about midway between the suture and

_the external margin; this angle is sometimes so prominent as

almost to form a carina, and generally it has a row of shining

granules topping it, especially at the base ; towards the apex there

is almost always a second carina, short ad oblique, and outside

this, near the margin, there is an indication of athird. The type

(P. quaternarius) is from Manilla; to this Planodes satelles of

When I proposed this genus some years ago I was unacquainted

with its two nearest allies, Planodes and Anancylus, and was

therefore very doubtful as to its affinities. The former of these

it most nearly resembles in habit, but differs in its short or almost

obsolete antennary tubers remote at the base, and in its normal

antenne; from the latter it differs in habit, shorter antennae

and the presence of raised lines on the elytra. The lower lobe

of the eye is much more frontal than is usual in this sub-family.

A second species has been described in the Journal of Entomology

(vol. i. p. 347) from Cambodia, and I have now a third species,*

also from Cambodia, which departs from the type in having its

prothorax more rounded at the sides, and its elytra shorter and

more convex; its abdominal segments also, at least the three inter-

mediate ones, are furnished with semicircular patches of coarse

hairs, as in Symphyletes and some other genera.

The word Eris had been previously used by Koch for a genus

of Arachnida; I have therefore altered it to Frets.

* This may be characterized as follows :—

Ereis ventralis.

E. fusca, sparse irregulariter griseo-pubescens; prothorace subtransverso,

lateraliter rotundato, minute granulato; elytris brevibus, convexis, ca-

rinis fere obsoletis, nigro-maculatis, preecipue post medium linea trans-

Brown, covered with a thin greyish, or sometimes nearly white

pubescence ; head and prothorax greyish or whitish, on each side,

commencing behind the eye, a dark or nearly black stripe; scu-

tellum triangular; elytra marked with darkish spots, giving them

a somewhat tessellated appearance, slightly depressed, each with

two longitudinal ridges, the inner more decided ; body beneath

reddish-brown and glabrous along the middle, clothed at the

sides, and especially on the abdomen, with a greyish pile; tibiz

and tarsi ringed with black and white; antennz black, twice as

long as the body in the male, shorter in the female, slender, the

base of all the joints, except the first two and last, with a narrow

ring of white.

Corethrophora, Blanch. Voy. au Pole Sud, iv. 301 (1853).

Caput antice quadratum, tuberibus antenniferis basi sub-

elongati, antici in maribus longiores, protibie subcurvate vel

in feminis rectz ; tarsi in utroque sexu equales. Mesoster-

num subangustum, antice dentatum.

M. Blanchard (ubi sup.) proposed the genus Corethrophora for

a species (C. semiluctuosa), which I am unable to distinguish

satisfactorily from Cacia. Almost the sole character to authorize

its separation is the stronger and more approximate antennary

tubers; but this character is modified in individuals belonging to

what I believe to be the same species—a species subject to such

Longicornia Malayana. 107

an amount of variation that its characters, if it were the type of

a genus, ought to be particularly strong. Confining Cacia to

those species which have a narrow mesosternum* toothed ante-

riorly, and the third and fourth joints of the antenne not thicker

than is usual, but the former much longer than any other joint,

there are still considerable modifications in the genus which it is

possible may lead to further division. Cacia setulosa, Pasc., from

Java, but not in this collection, furnished with numerous erect

hairs over the upper surface, is one of the most aberrant. Another

species, Cacia compta (post, p. 112), has a tuft to the third as well

as the fourth joint of the antenna, but this is so far untrustworthy

that the tuft is sometimes absent from individuals of those species

which appear to have it normally. The type of the genus, Cacia

spinigera, Newm., has a little spine, or rather tooth, on the apex

of the third antennal joint, but this Mr. Newman very properly

considers as of specific value only, his second species, C. aspersa,

being without it. Mr. White has described a species from China,

which he has named Cacia latifasciata, but which strictly cannot

be considered to belong to this genus. The species appear to be

subject to very considerable variation; in nearly all the fifth

joint of the antennz is wholly or partially white.

* A Cacia-form, not belonging to the Wallacean Collection, which is ex-

cluded by having a broad flattish mesosternum, may be shortly characterized

here. The specimen is a female,

THERIPPIA.

Glabrous, black, and shining, with small intricate pubescent patches of

white, tinged here and there with rose; these occur irregularly on the head

and prothorax, but are collected into three bands on the elytra—viz., at the

base, middle and apex; the femora are spotted, the tibie have a white ring

in the middle; the tarsi are black, with the two basal joints white; the body

beneath is black and shining, with a very thin greyish pubescence; the

antennz have the second joint and bases of the remainder white, with a small

black tuft on the fourth; the last six joints are together not more than half as

long again as the fourth.

From a large number of specimens now before me I have not

the slightest doubt that all the names given above are referrible

to one and the same species. Under ordinary circumstances I

should have taken the earliest name, but putting aside the ob-

jection that this is simply a barbarism, and that at the very mo-

ment of giving it the author believed that though ticketed (indiquée)

from Vanikoro the insect nevertheless came from New Guinea

or the Celebes, and its adoption, therefore, would be only to per-

petuate an error, the obvious convenience of a collective desig-

nation for a species subject to such an extraordinary amount of

variation becomes almost a necessity.

The names of these four forms may be maintained as so many

centres from which to survey the species. Starting from the com-.

monest forms, which seem to group themselves round C. histrionica,

we find that they are black, with a white band across the elytra pos-

teriorly, the apex, scutellum, and elytra around it, also white, A

stripe from the scutellum passing along the suture joins the band,

and then we have the Corethrophora semiluctuosa. Through several

varieties the white increases, the black between the band and stripes

gradually diminishing and disappearing, in which state it is the C.an-

thriboides. Sometimes there is a black spot on the white near the

shoulder, and the sutural stripe is prolonged to the apex; this gives

two black patches to each elytron. In one beautiful specimen the

Longicornia Malayana. 109

apical black is crossed by three pure white lines, and there is a

dash of black from each shoulder. Returning to C. histrionica

we have in one direction the white entirely disappearing, except

the central thoracic stripe prolonged a little on the scutellum and

elytra, and in another the band and sutural stripe taking a finely

linear form. This is about the most simple of all the varieties,

but starting from this we first see a little white dash near the

shoulder, and then this is directed obliquely inwards with a gentle

curve until it approaches the middle of the elytron, when it takes

another turn downwards and backwards, and joins the posterior

line. When in addition to this there is an ocellate spot near the

apex we have “ Vanikorensis.” Generally there are only inde-

finite indications of this spot.

Dark brown, with an interrupted greyish-yellow pile; head and

prothorax rather finely punctured ; the latter transverse and its

punctures surrounded by the naked derm, these portions some-

times confluent and forming black irregular patches ; this occurs

also on the elytra, but here the principal patch takes the form of

a broad curved band behind the shoulders, sometimes another

distinct but irregular band towards the apex, bordered or not by

a fine line of yellow hairs, these lines occasionally dividing the

band into small patches, or the whole of the elytra behind the

shoulders may be more or less bare of pubescence except a little

towards the apex, the ridge at the base granulose; scutellum

sometimes pale buff; body beneath brown, shining, the sides with

a fulvous-brown pile ; legs fulvous, more or less varied with brown

or black, the tibize generally black or dark brown with the

middle third fulvous, the tarsi of the two posterior pairs with the

two basa] joints dark, the remainder, except the claws, fulvous ;

antenne with or without a black tuft at the apex of the fourth

joint; the third joint sometimes furnished with a slight spine at

its tip (in the Sarawak examples).

Yellowish-red to dark brown, with intricate well-marked lines

of greyish or yellowish-grey; on the prothorax there are two lon-

gitudinal lines on each side, together somewhat resembling the

figure 8; on the elytra these lines are chiefly transverse and so dis-

posed as to leave three dark irregular band-like patches; the

posterior one is especially band-like, and sometimes becomes a

complete band; at other times these patches are divided, or the

fine greyish lines shade off into a nearly uniform colour, leaving,

however, the pattern untouched; antennz unicolorous without tufts,

or tufted with the fifth and base of the fourth joint white; tibiz

with the middle or whole of the basal half pale grey or white.

This is also a suspicious species, having precisely the same

style of coloration on the prothorax as the last two, with the addi-

tion of a patch on each side, but this is also the case with some

individuals of C. iniricata. In C. plagiata the prothorax is very

much broader than in C. scenica, (but even this character is vari-

able in C. instabilis). As to the elytra, we have only to connect

the three bands of C. intricata by a stripe along the suture and

carry the stripe down to the apex, and we have pretty nearly

C. plagiata. The two specimens before me show some differences,

and probably belong to a variable species, but the evidence is not

sufficient at present to justify its union with the last.

The cylindrical prothorax, the thickened 2nd, 3rd, and 4th

it carried its antenne “ straight and close together, appearing like

I have separated this genus from Cacia, to which I formerly

are shorter and the body more depressed than in any species of

Cacia. My original specimen was much worn. These insects

were taken flying in the jungle.

This genus was accidentally omitted from the table (ante, p- 96),

but it a stand after Ipocregyes, from which it differs in its large

head, elongate mandibles, short scape strongly produced at the

apex, stouter legs, particularly of the fore pair (which are both

larger and thicker in both sexes), and other characters. The

curious little insect, at present the only member of the genus, is

remarkable for its large head and short scape, this latter character

being quite at variance with those of its sub-family; itis, however,

so nearly allied to other species of the group, that it could not,

without violence, be separated from them.

to Lachnia, which, from his description, appears to belong to the

Alypselomine. The genus is well represented in Africa, and on

the mainland of Asia. Mr. Wallace’s Collection contains nine

very distinct species, all, with some exceptions, tolerably homo-

geneous, but owing to the mixed and indefinite style of their

coloration very difficult to describe ; and this difficulty is increased

from the circumstance that individuals vary among themselves.

Generally the derm is dark brown and glossy to a certain extent,

Longicornia Malayana. 117

sometimes entirely covered with the pubescence, at other times the

pubescence is so thin that the derm may be readily seen, and

imparts its colour to modify the general effect, or portions of it

may be absent or nearly so, and then there are spots or patches

of irregular shape, not always exactly the same even in the same

species.

There is also frequently a little dark ring formed round the edges

of the punctures ; these in the following descriptions I have spoken

of as “‘puncta” or ‘points’ to distinguish them from ordinary spots

or ‘macula.’ The puncturation, otherwise, is everywhere very

fine, and is not to be seen without a lens. The mesial line on

the head is very slight, scarcely forming a sulcation. The pro-

thorax, shorter or more transverse in the female, is, sometimes,

much broader at the base than anteriorly, but this is a character

which can scarcely be realized by description, unless when very

decided. The disc is generally marked by a more or less V-shaped

impression anteriorly, posteriorly a similar mark is reversed, the

apices of the two being connected by another short longitudinal

impression ; the anterior mark, and sometimes the posterior, runs

into a transverse groove; generally, too, the disc has two small

tubercles, one on each side of the longitudinal impression. The

slight variations which occur in these characters are very difficult

to define so as to be thoroughly intelligible.

In nearly all the species the antenne are annulated with white

or pale grey; this colour is found at the bases of most, sometimes

of all, the joints, beginning with the third. Exceptin C. undulata,

the elytra are rounded at the apex. In C. lacertosa the fore legs

of the male are longer and stouter than the intermediate and

posterior ; in a less degree, this is also the case with C. polyspila,

C. pardalis, and a few others not in this Collection. This character

gives them a somewhat different habit from the more normal

species. ‘The males have longer antenne than the females, and it

may be generally noticed that their elytra are much more trigonate

in outline.

The form of the prothorax, in conjunction with the normal

proportion of the length of the scape to that of the third joint of

the antennz, and the non-unguiculate apex of the last joint, will

readily distinguish this genus from Coptops; while the rounded

prosternum, inter alia, separates it from Clyzomedus. The three

species are on the whole tolerably homogeneous in point of form ;

in size, judging from the few specimens before me, there is a

little discrepancy.

The type of this genus is a Manillan insect (A. transversa),

described with two other species by Mr. Newman in 1842. Mr.

Wallace’s researches have added nine more to the list, of which

five have been described by Mr. White, and another by myself.

124 Longicornia Malayana.

Besides these the late M. Mouhot obtained three species in Cam-

bodia, which were published by me as Ayelaste, but only one of

which can be retained in the genus as here defined.* I have

also species in my collection from Pulo Penang and from Patani

in Malacca,} and another from Java, unpublished, is the Chaero-

morpha pigra of Dejean’s Catalogue. The species with scarcely

an exception are remarkably distinct, and, omitting one, which is

only placed here provisionally, the genus, as now limited, is a

very natural one. Nevertheless there are certain peculiarities

which it may be well to notice. In A. zrrorata, there is a very

decided process on the side of the prothorax, not exactly a tu-

bercle or a tooth (as in 4. Polynesus), and there is a little angularity

also in A. sobrina and A. sulphurea. The male 4. Wallacet has the

antennz scarcely longer than the body, while in 4. sobrina they

are half as long again. In the male of a species from Penang

(not yet published), and apparently so closely allied to 4. Wallacet

that I at first thought it might be a variety of it, the antennz are

twelve-jointed ; the supplementary joint is not simply an append-

age of the eleventh, but in all respects a true and perfect joint.

A. callizona has the distal end of the protibize densely tufted. In

the female of A. Polynesus the antenne are thickened towards the

apex. Excluding 4. basalis, which cannot be considered a true

Agelasta, the genus might be divided into two sections, Ist, those

with the third joint of the antenne longer than the scape, and

2nd, those in which it is shorter ; but between these there is the

Manillan A. transversa, in which they are about equal. This,

therefore, seems to be one of those genera in which the com-

parative lengths of these joints (which generally afford most reliable

characters, and this may also be said of the antenne to a certain

extent), are to be considered as only of secondary importance.

All the members of this genus met with by Mr. Wallace were

found on fallen trees, but “ fell off and lay as if dead when dis-

turbed.” 4. Nenwmanni was found “ flying above newly fallen

timber.”

yellow on the abdomen; legs rather obscurely ringed with dark

brown and grey; the tarsi, except the extremity of the claw-joint,

pale ashy; antennz dark brown, the bases of the joints, from the

third inclusive, pale ashy.

Length 6 lines.

This species differs considerably from the rest of the genus ;

but in the absence of any decided character, and as I have only

a single example, I am unwilling to propose a new genus for its

reception. It is much less robust in its habit, narrower, the sides

more parallel, and although a male, the fore-legs are not very

perceptibly thicker or longer than the others; they are, however,

slightly curved, which, with other discrepancies, prevents it being

placed in Sorbia.

A beautiful insect, having a singular resemblance to Agelasta

callizona in its coloration, is the sole representative of this genus.

From Agelasta, however, it is abundantly distinct, not only in

the form of the prothorax and mesosternum, but also in the

straightness of the protibice,* and the elongated, parallel, and di-

lated anterior tarsi, while on the prothorax little glossy black

granulations take the place of punctures.

scarcely longer than broad, the sides regularly rounded, the disc

with black glossy granules; scutellum somewhat quadrate ; elytra

punctured, chiefly at the base, with a few scattered granules, the

median band rather broad and of a clear pale brick-red colour,

the apex also of the same colour; body beneath dark brown, with

132 Longicornia Malayana.

The anterior coxe in this genus are remarkably produced, while

the prosternum scarcely rises above their roots, and the mesoster-

num is gently rounded anteriorly, and neither dilated nor toothed.

The crest at the base of each elytron is very small, and is accom-

panied by two slightly elevated lines externally. The transverse

impression on the prothorax is joined behind by a shallow longi-

tudinal excavation, dividing the disc into two very slight lobes.

In habit and dullness of coloration the genus resembles some

species of Praonetha.

slightly punctured, abruptly narrowed anteriorly, behind which

its sides are nearly parallel; scutellum nearly semicircular ; elytra

irregularly punctured, the punctures nearly confined to the basal

half, crest at the base small and tooth-like, two raised lines ex-

ternally, not extending to the apex, a light grey spot at the end

of the innermost, and a few obscure greyish patches, chiefly towards

the base; body beneath brownish ; legs and antenne very slightly

The characters which separate this genus from Golsinda are

principally the comparatively short and obconical scape, the sim-

ple mesosternum, the toothed prothorax and the irregular elytra.

Olivier, who has described and represented one of the species(Tom.

iv. No, 67, pl. xx. fig. 151) under the name of Cerambyx annula-

tus, says, however (p. 95), ‘* thorace mutico ;”” but although small,

there is undoubtedly a tooth on each side, besides the tooth-like

tubercles on the disc, and in another species found in Laos and in

Pulo Penang, it is far more strongly developed, especially (and this

is very remarkable) in the female. The males in this genus, be-

sides the much greater length of the antennz, have a very pro-

minent lamina at the tip of the seventh joint, this is rounded at

the end and its sharp margins fringed with short hairs; there is

a tendency to the same structure in the sixth as well as in the

fifth joint, but in the latter it is less evident, and traces of these

little prominences are also obvious enough on the antenne of the

There is very little beyond the form of the prothorax to sepa-

remarkable than important.

This is one of those isolated genera, of which so many occur

among the Longicornia. The head is much smaller than is usual

in this sub-family, and is in a line at the sides with the prothorax,

while, from the narrow elytra and receding shoulders, there is not

that disproportion at the junction between them and the prothorax

which we find in the other members of this group. In these

respects it approaches the Apomecynine, but the elongate scape

and longer anterior legs, especially in the males, point rather to

a location in the present sub-family.

appear to be out of place in this sub-family ; perhaps, indeed, it

might have been better ranged with the Apomecynine. I have

only seen a single example, apparently a male, which, according

to Mr. Wallace’s note, was found “ under fallen timber.”

the apex of each elytron bordered with a white line on its sutural

margin, which is connected behind with a transverse one; body

APOMECYNINA.

Many of the genera of this sub-family, as it is here limited,

have been, hitherto, widely dispersed in systematic works; but,

taking their general characteristics into consideration, we get a

long series of forms, many of them very remarkable, but which,

when seen together, seem to be sufficiently connected to justify

their juxtaposition.

The body of these insects is generally elongate, and either

cylindrical, fusiform or irregular, that is, with the elytra broader

than the prothorax ; at the same time the legs are below the usual

Longicornia Malayana. 139

length, and often very short, so as not to extend beyond the

abdomen. The prothorax is rarely spined or toothed, and is

frequently not broader than the head; the latter is more or less

quadrate in front, with the antennary tubers approximate at the

base, except in Euclea, and a few other genera, and the eyes are

small and emarginate. The elytra are occasionaliy crested, but

in many cases these crests are simply expansions or elevations of

a carina or raised line, and have then no generic importance.

The abdomen has sometimes all the segments except the basal

one of equal length. But it isin the antenne that the most frequent

modifications of structure are met with. Sometimes they are entirely

plumose, at other times the plumosity is confined to one or more

particular joints, either surrounding them entirely or forming a

dense or a pectinated fringe beneath them. In many genera it is

difficult to detect the articulations of the terminal joints, but in

Cloniocerus the very reverse of this prevails, and each joint after

the fourth is drawn out on one or both sides at the tips. When

very short (and they are rarely longer than the body) it is owing

to the last seven joints being unusually abbreviated. The scape

is not produced, and never scarred at the apex.

The affinities of the Apomecyniné are numerous. To the Nipho-

niné they approach through Pravnetha on the one side and A’go-

momus on the other, while Diexza in the preceding sub-family might,

as I have already observed, have been equally well placed in this.

From such short-footed groups as the Phyteeciine and Obereine,

they may be distinguished by their simple claws, and from the Sa-

perdine by the emargination of the intermediate tibia, The Hip-

popsine have their antennze contiguous at the base; this is never

the case with the Apomecynine. It is scarcely necessary to observe

that none of the characters distinguishing secondary groups are

absolute. Here and elsewhere are ambiguous genera, whose posi-

tion, in the absence of any obvious affinity, depends on the import-

ance to be attached to certain points of structure. Perhaps the most

aberrant genera in the sub-family are Cloniocerus and Desmiphora,

but these are bridged by such forms as Apodasya, Atelodesmis,

Eupogonius, &c. But none of these belong to the Malay fauna.

Albana and Stenidea are the only European exponents of this

sub-family. Mycerinus (which although represented in Africa

and Australia has not been found by Mr. Wallace) and a few

other genera recently added to our lists represent it in Australia.

In America there are Agennopsis, Eupogonius, Phidola, Eudesmus,

Eupromera, Hebestola, and many more. Africa contributes Tec-

ton, Enaretta, Cormia, Elithiotes, Cymatura, Sophronica, and

140 Longicornia Malayana.

others. Most of the Asiatic genera occur in the Malayan Archi-

pelago; there are, however, others yet undescribed, which so far

appear to be Asiatic only.

There are twenty-eight genera in the collection, and one hundred

and sixty-four species. In the following table of the genera I

have intentionally given prominence to the most obvious charac-

ters, rather than the most important.

is from Java. From the clause ‘‘ antennarum art. 2—38 et 5—11

made of the fringe clothing the upper part of the third joint, |

have come to the conclusion that the example described below is

a distinct although nearly allied species, the more so that I have

recently seen another species from Pulo Penang, to which the

same remarks may be applied.

Four well-marked species of this genus are in the collection.

Three of these have basal crests on the elytra, varying, however,

considerably in their extent and character, while the fourth is not

only without the crests, but also without the anterior prothoracic

tooth. In other respects it is so conformable that it scarcely

seems justifiable to separate it generically. The curious little

hairy comb-like brushes fringing the last five or six joints of the

antenne are, I think, not confined to one sex, at least one of the

specimens before me appearing to be a female. The last seven of

these joints are so short that together they scarcely exceed half

the length of the four preceding.

punctures, constricted anteriorly, the constricted portion forming

a narrow margin, over which the larger punctures do not extend ;

elytra irregularly punctured, a small black granule, generally

tipped with a whitish scale-like hair, seated on the edge of each

puncture anteriorly, at the base of each elytron an elevated ob-

crests of the same kind posteriorly on the declivity towards the

apex, the exterior of the two being the smallest; body beneath

Dark brown, very slightly pubescent, without granulations,

although between some of the punctures the derm is so pinched

up as to assume in some places the appearance of them; head

rugosely punctured, with patches of very pale ferruginous hairs ;

prothorax coarsely punctured, no anterior tooth, but a very small

one on each side behind the middle; scutellum very short, trans-

Perhaps this genus might have been better placed in the pre-

ceding sub-family, on account of its quadrate front and elongate

scape; but as the latter is entire at the apex, and the antenne

have the same curious pectinated fringe as in Synelasma, I prefer

to consider it a member of the same group as the last-mentioned

genus.

From Praonetha this genus differs in the toothed prothorax

gradually enlarging to the base, the more convex elytra giving the

nearly linear antennee, the produced mesosternum, and the toothed

intermediate tibiae.

The cylindrical form of the antennal joints, masking, as it were,

the lines of articulation, and the lateral tooth of the prothorax,

distinguish this genus from Praonetha. From Atmodes it differs

in the form of the scape and the convexity of the prothorax and

elytra.

Covered, except on the abdomen, with a short, scaly, dark-

brown pubescence, mixed with a few larger and whitish hairs,

many of which stand alone at the bottom of the punctures ;

upper surface rather remotely punctured, the brown colour on the

head and prothorax, continuous with a narrow transverse band at

the base of the elytra, lighter than the rest, but the line between

the two very distinct; a white spot on each side of the prothorax

underneath; nearly on the middle of the elytra a large oblique

snowy-white stripe or patch, and behind this, and on the apical

This genus has the habit of Ropica, but is more robust, and

differs in the antennz and legs; the tarsi, particularly, are re-

markably short. The eyes are finely granulated, an unusual

character in this sub-family, and the inferior lobe forms a slightly

conical projection.

The large basal joint of the anterior tarsi is probably a character

distinguish the genus. My specimen has a broad darkish band

A fine and very distinct genus, remarkable for its broad front

and elevated vertex, and particularly for its elongate propectus,

as in the Monochamine. The prothorax has a well-marked tooth

on each side (not two, as Mr. Newman’s description seems to

imply) in the type EL. albata, but this becomes a mere tubercle in

the other species, and in one, £. nigritarsis, there is scarcely a

vestige of it. There are four* Manillan species in addition to the

two here described.

spots, one common to both in the centre, at the base of each, two

sometimes conjoined, or two in addition, behind the outer one ;

behind the middle a transverse patch, and another oblong one at

the apex, or these more or less combined, &c. ; body beneath and

scutellum narrow, rather pointed ; elytra pubescent, ochraceous,

the spots invariably with a punctured centre, behind the middle a

at the sides, scutellum smaller, and elytra with well-marked punctures. E.

Atmodes is better known, perhaps, under its old name of Milo-

thris, Dej., which M. Thomson has changed in consequence of its

having been previously used for a genus of Lepidoptera. The

genus is related to Mycerinus and Apomecyna, but may be distin-

guished (inter alia) by its irregular and toothed prothorax, and

its strongly elevated and produced sterna. The type is a well

known and very common insect, whose synonymy has latterly

been strangely complicated.*

The short setaceous, or occasionally nearly linear antenne, not

approximate at the base, with the obsolete articulations of the

terminal joints—the two apical, especially, looking as if they

formed but one—and the somewhat depressed, elongato-ovate

outline, will readily distinguish this genus. The type is the Lamia

histrio of Fabricius; so at least it is generally stated, but the point

must have been determined more by tradition than from his de-

scription. Besides Apomecyna cretacea, Hope, there are two forms

of this species in collections, or perhaps it would be more correct

to say that there are two species under the name of histrio. One,

besides other characters, has a thicker scape, the apices of the

elytra nearly transversely truncate, and the antennz unicolorous ;

the other has the scape smaller, is more thinly covered with pile

so that the punctures are readily seen, the apices of the elytra are

obliquely truncate, and the fourth joint of the antenne is generally

white, except at the tip. Of the first* I have examples from

Dacca and Ceylon; examples of the second, from Bombay and Bris-

bane (Australia), agree tolerably well together, while those from

Batchian and Saylee have much stouter antennze, and one from

Natal is very decidedly broader, with the three series of spots

nearer to the apex. Whether these, considering the vast dis-

tances which intervene between their respective habitats, are any-

thing more than local sub-species, may be doubted. Mr. Wallace’s

specimens are identical, I think, with those usually referred to 4.

histrio, the commonest of the Indian species. ‘The normal Apome-

cyn@ have the third antennal joint twice the length of the scape ;

a species from South Africa, however, which, in other respects,

does not differ generically, has it nearly equal. This I have

received under the name of Apomecyna sparsuta, Germ. I cannot

find that it has been published. Several insects referred to this

genus will have to be separated.

* This may be named 4. neglecta.

the slightly depressed, not convex, elytra.

SESIOSA.

Characteres ut in Apomecyna, sed oculi divisi, et pro- et meso-

Of the two differences between Sesiosa and Apomecyna, the first

is one of degree only, the second is more important. In Apome-

cyna the sterna gradually slope down towards one another, and

the anterior coxze are thus more or less widely separated from

the intermediate, whilst in Sestosa, which has the sterna elevated,

with necessarily opposing faces, these coxze are approximate, and a

different appearance is given to the pectus. It is necessary to see

that the prothorax is neither unnaturally bent on the medipectus

nor stretched too much in the opposite direction. One of the

examples before me was found by Mr. Wallace “on the branch

of a dead tree,” another is from Pulo Penang.

The very unusual character, among the Lamide, of truncate

palpi will at once distinguish this genus, which in outline re-

sembles Apomecyna. The fore-tibize are also remarkable; instead

of expanding at the extremity, they contract and are rounded at

that part where the tarsi are inserted, and are, in consequence,

entirely destitute of the mucro, which is a common character in

nearly all the Longicornia. ‘The eyes are unusually large, their

lower border extending to the base of the mandibles.

The general appearance of this insect is very similar to Calym-

mophis flavo-variegata, Thoms. (one of the Mesosine), but the head

in that genus is very different, and somewhat resembles the

Onocephaline, i. e. the antennary tubers approximate and have an

upward direction. Dymascus is very distinct from anything

known to me.

The two species composing this genus have a very similar habit,

but differ technically in two or three characters, which however

do not seem to be of sufficient value to justify their generic sepa-

ration. The first species, Zorilispe fulvisparsa, has the eyes very

deeply divided, and a longer scape than the other; and is, propor-

tionally, somewhat stouter. The genus is allied to, but quite

distinct from, Atimura.

In Atimura terminata,* the. type of this genus, the anterior

cox are prolonged on their inner edge into a short spine; as

this is not the case in the two species described below, I have

omitted the character in the above definition. The genus is well

limited by its short stout scape, and perfectly cylindrical elytra,

truncate at the apex. A. bacillina is almost an exact counterpart,

barring a few minute but most important particulars, of the

Australian type, and is interesting as a very rare instance of such

conformity among the Longicornia. From their cylindrical form,

and their colour, these insects resemble little broken twigs or

sticks.

large black punctures; prothorax moderately punctured, with

five obscurely elevated lines, its posterior angles produced, the

sides slightly incurved; scutellum rounded behind; elytra irre-

gularly punctured, with four raised lines on each, the innermost

The principal characters to distinguish Sthenias from its allies

are the strong antennary tubers and the slender curved scape.

The type is an old Fabrician species,* and with this must be placed

S. crocatus, Oliv., a Manillan insect, overlooked by M. de Castelnau,

but described by Mr. Newman as a new genus and species under

the name of Thysanodes jucunda. These, I believe, are the only

true exponents of the genus known at present. The individual

described below is the only one in Mr. Wallace’s Collection; it is

much darker than the Indian specimens. Two species described

by myself must be separated from the genus as here defined.

* I cannot reconcile it, however, with the Fabrician description of the

elytra, ‘‘ basi tuberculis duobus elevatis.”

+ Each of these will represent a distinct genus, which I briefly charac-

terize here, for comparison with Sthenias. The first is—

In some respects this genus may be considered as interme-

diate between Sthenias and Xylorhiza. All three genera are

distinguished by their strong antennary tubers, which, being

approximate or even contiguous at the base, create, as they di-

verge outwards and forwards, a deep hollow in that part of the

head between them. From each other they may be distinguished

at once by the form of the scape, slender and curved in Sthenias,

stout and elongato-cylindrical in “tholopus, and thick at the apex,

gradually contracting towards the base, in Xylorhiza. There are

other points of difference, which will be seen on referring to their

characters. It may be mentioned that between Sthenias and

XAylorhiza, the Comte de Castelnau places nineteen genera. It

should be stated, however, that the latter is a most remarkably

distinctive genus in habit, although in its technical characters it

differs very slightly from Sthenias. The two species of Atholopus,

described below, are very similar, although one is much darker

than the other, but the apices of their elytra will at one distin-

guish them.

A grand and well-known species is the type of this genus, but

I have so far generalized its characters as to include Xylorhiza

spumans (Guér.?) and a few others yet undescribed. Unless we

limit Xylorhiza to X. venosa, I do not see how Cymatura, Gerst.,

is to be distinguished from it, and if we adopt Cymatura (on ac-

count chiefly of its spined prothorax), we should have either to

refer to it a number of very incongruous species, or to provide

for them new genera, which would be hardly more desirable.

Latreille gives a very poor figure of the type in the “ Régne

Animal,” iii, pl. xviii. fig. 7, under the name of “ Lamie veinée,”

but it is not mentioned in the text.

The diversity of form to a certain extent of many of the species

here brought together may, no doubt, be objected to, but, after a

careful examination, I cannot see that anything like a satisfactory

limitation can be established even in dividing them into sections,

although I have attempted to do so, but solely with a view to

facilitate their descriptions. The whole, when fairly compared,

and not putting extremes into juxtaposition, will, I think, be

found to compose, considering its great extent, a tolerably ho-

mogeneous group, which a practised eye will at once distinguish.

* The following, described by me as a Praonetha, must be separated from it

to form a new genus.

164 Longicornia Malayana.

So far as my materials have allowed, I have had little doubt as

to the distinctness of most of the species here described; the

technical characters are, however, so slight in themselves as to

make very decided diagnoses impossible. The colours of the

derm are brown of various shades, with a pubescence of grey of

various shades, modifying each other according to the density of

the latter, with spots or patches or lines, more or less distinct, or

mere shades of more or less intensity. Some individuals are

darker than others, or their markings may be nearly obliterated,

so that it is very difficult to say what characters are to be relied

on; or, if a larger series of specimens were available, it might be

that many forms here described would be found to belong to one

variable species.

On those species with crested elytra Mr. Newman has formed

his genus Plerolophia * (and Notolophia), but in some the crests

are so slight that it is hard to say if they really exist; the passage

is almost insensible.+

Respecting the habits of these insects, Mr. Wallace says that

they are found in large numbers on the tops of bamboo pali-

sades, used in fencing, whenever there is any moisture oozing

from them.

STESILEA.

Characteres ut in Praonetha, sed prothorax antice vix angustior,

Although the technical characters of this genus are not very

definite, it is, nevertheless, a very natural one, and, but for the

absence of the small anterior prothoracic tooth, might have been

referred to the Niphonine.. ‘The species are all very homoge-

neous in point of size and colour, but the spots on the elytra may

probably prove to be an uncertain character.

A number of small and obscurely marked species are comprised

in this genus; they are on the whole tolerably homogeneous,

although the short compact form of the majority is departed from

in a few of its members. ‘The transition is, however, gradual, as

usual, and there is no other character to separate them. The

scape of this genus is variable in size, and there is sometimes

a slight but sufficiently obvious difference even in the same

species. The head and prothorax are generally strongly, although

rather finely, punctured ; the punctures on the elytra are much

coarser, and are occasionally subseriately arranged, but only in

the centre of the disc; the pubescence, except on the head, is

strictly confined to the spaces between them. The genus is only

represented at this time in Australia by a single species (Ropica

exocentroides, Pasc.).* Oopsis, Fairm., restricted to the Fiji and

other Pacific Islands, is known by its strongly clavate femora.

Characteres ut in Ropica, sed antenne lineares, haud fimbriate.

It is impossible to retain the species on which this genus is

founded in Ropica, without violating a character which is constant

throughout the latter group. The scape, variable in Ropica, is,

in the two species described below, shortly ovate, but the coloration

and apparent glabrosity (for the pubescence is visible only under

the microscope) give them quite a different habit. The punctures

on the prothorax and elytra are, as in other members of the sub-

family, furnished at the base each with a triangular scale-like hair.

depressed above, The characters, although not very decisive, are

tolerably constant for so large a group. The type, Sybra stig-

matica, is nearly allied to a Madagascar species—the Saperda

geminata of Klug. I have divided the genus into three

sections, the first having the apex of each elytron broadly

wedge-shaped, and the sutural side of the wedge with a convex

outline; the second section has a narrower and more projecting

wedge, and the sutural side more or less concave; the third sec-

tion has each elytron rounded at the apex. Sybra incivilis, Pase.,

from Port Denison and S. posticalis, Pasc., from Hong-Kong, be-

long to the first,and S. acuta* from New South Wales, to the second.

The first, and by far the largest, section is divided into sub-

sections dependent on the comparative breadth of the prothorax

at the base. The species are all of small size, with a derm vary-

ing from testaceous to dark brown or nearly black, and covered

with a generally scanty greyish pubescence, almost invariably

relieved by spots or patches of white, grey or brown, but often so

indistinctly as to require a strong lens to distinguish them. Un-

fortunately there is reason to believe that the species vary con-

siderably among themselves, and particularly that a minute

description of the coloration would only be applicable to certain

individuals; at the same time the distinctions to be drawn from form

and sculpture are not always sufficiently decided to allow of their

being clearly stated. With a large number of examples, I can

conceive that it might be impossible to divide them satisfactorily

at all. In fact I have put aside several that I can neither resolve

into species or quasi-species, nor refer to any here described. In

two or three instances in which Mr. Wallace has marked the sexes

of the same species, the differences between them consist chiefly in

the broader prothorax and somewhat longer antennz of the males.

A few of the species of Sybra have their tibiz slightly longer than

their tarsi, but then the legs are all equal or nearly equal in length ;

but in this genus there is a marked departure from that type, and

indeed from the sub-family, the intermediate and particularly the

posterior pair being very decidedly longer. The coloration and

sculpture are, however, the same as in Sybra. The only repre-

sentative at present of the genus has a certain resemblance to

Eunidia nebulosa, Er., which has suggested the name.

DorcaDIONIN&.

Only two species of this sub-family occur in the Wallacean

Collection, both having a very close resemblance to the European

genus Parmena. No doubt many more forms remain to be dis-

covered, as the Asiatic and Australian members of this group are

amongst the rarest of insects known, and whilst new species occa-

sionally occur, it is rare indeed to see a second example of an

older one. They are probably for the most part nocturnal insects

like Parmena, lurking by day under stones or fallen trees, or in

hollow stems of plants, rarely straying far from their hiding-places,

in which their race, in some cases,* have probably existed from

the time before the earth received its present form.

One of the peculiarities of this sub-family is the power which

many species possess of making a creaking sound when seized or

disturbed. This sound. is produced by the movement of the

prothorax on the mesothorax, which, at that part, appears to be

perfectly smooth, but under the microscope is seen to be trans-

versely striated. It seems to me that these sounds are naturally

caused by the attempts of the insect to escape, and that it is not

a power given as a means of protection to frighten its enemies.

The rounded or obsolete shoulders, always connected with the

absence of wings, or at most the presence of very rudimentary

ones, is the principal feature of this sub-family, which otherwise

varies considerably. ‘The typical form appears to be the genus

Phantasis of M. J. Thomson, leading away on one side to Micro-

tragus, Athemistus, Dorcadion, Parmena, &c., and on the other to

Blax and Xylotoles through Deucalion, Dorcadida, Brimus, and

Phrissoma. Hoplonotus, Auxa, Aconodes, and a few others, must

stand for the present as more or less isolated forms. The

* Mr. Wollaston (Insecta Maderensia, pp. 480 et seq), in an interesting

account of the discovery and habits of Deucalion desertarum, says, ‘‘ When

we consider indeed the apterous nature of Deucalion, its subconnate elytra,

and its attachment (at any rate in the larva state) to the interior of the

stems of particular local plants, or its retiring propensities within the cre-

vices of rocks, we are at once struck with the conviction that, during the

enormous interval of time which has elapsed since the mighty convulsions

which rent asunder these regions terminated, it has probably never removed

many yards from the weather-beaten ledges which it now inhabits.’”’? Another

species, which Mr. Wollaston has referred to the same genus (D. oceanicus),

was found on one of the Salvages, a mere cone of rock in the midst of the

ocean, and must have existed there before the Atlantic islands became

detached from the great continental land, of which they once formed part.

Longicornia Malayana. 223

affinities of the Dorcadionine appear to be chiefly between the

Apomecynine and the Lamune : the genus Blax showing a tendency

towards the Tmesisternine. Several species betray a striking

resemblance to genera of the Curculionide inhabiting the same

countries with themselves.

The geographical distribution of the Dorcadionine is somewhat

peculiar, inasmuch as only one species (Taurorcus chabrillacii,

Thoms.) has as yet been found in South America, except Chili,

where Hoplonotus and Microcleptes appear to be common.

Mexico and Texas have Moneilema and Echthistatus, and Cali-

fornia has Jpochus. In Europe we have only two genera, Dorca-

dion and Parmena, Africa has some very remarkable forms, as,

for example, Oriathus, Opsies, Stenoparmena, Auxa, &c. (the last

from Madagascar). From Asia we may expect many novelties;

at present we may mention Dorcadida, Morimopsis, Plectrura and

Aconodes.* Others in collections are not yet described.

There appear to be only two Australian genera—Microtragus

and Athemistus,+ but there is reason to believe that they are both

numerous in species. New Zealand, so excessively poor in its

specific forms of animal life, is comparatively well represented.

Here, and peculiar to those islands, are Ceregidion, Hexatricha,

Xylotoles, and Somatidia, all isolated forms so far as New Zealand

is concerned, although the last is closely allied to the European

Parmena. Islands, and probably also mountain masses of low

elevation, appear to be particularly favourable to the existence of

members of this group. Thus from Madeira and the Desertas

_we have Deucalion, from the Canaries Lepromoris{; Lord Howe’s

Island gives us Blax, and New Caledonia Tricondylodes.

The species collected by Mr. Wallace form two

Tt was found in the Himalayas, near Darjeeling, I believe. There is another

form from the Neilgherries. The hill-districts of India have doubtless many

more.

+ I believe, however, that my genus Mesolita will be eventually referred to

this sub-family.

224 Longicornia Malayana.

Dasverrus.

Caput antice latum, tuberibus antenniferis validis, distantibus.

Ocul parvi, profunde emarginati. Antenne corpore breviores;

scapo breviusculo, subcylindrico ; articulo tertio longiore ;

czeteris sensim brevioribus. Prothorax subquadratus, lateri-

bus antice dentatus. Llylra ovata. Pedes robusti; femora

medio incrassata; tébie@ intermediz integre ; tarsi equales.

Pro- et meso-sterna elevata.

The type of this genus is very much like a large unicolorous

specimen of Parmena Solieri. The genus is, however, sufficiently

distinct from Parmena* on account of its prothorax, sterna and

intermediate tibiz. The anterior acetabula are broadly angulated

externally.

Dasyerrus pilosus. (Pl. X. fig. 8.)

D. fuscus, dense griseo-pubescens, pilis numerosis elongatis

dispersis.

Hab.—Flores, Timor.

Dark brown, covered with a dense greyish pile, slightly mottled

with fulvous, and having numerous slender hairs scattered over

the upper surface, legs, and antennz; head narrower than the

prothorax, thinly punctured in front; prothorax coarsely punctured,

nearly quadrate in the Flores specimen (¢), more transverse

in the Timor one, which is apparently a female; scutellum semi-

circular ; elytra oblong, rather wider than the prothorax, coarsely

punctured, slightly rounded at the sides, the shoulders nearly:

obsolete, the apex rounded ; body beneath and legs dark brown,

sparingly pubescent, the tarsi ashy; antennz scarcely so long as

the body in the male, much shorter in the female.

Length 43 (& )—53 (¢ ) lines.

* This genus is generally attributed to Latreille (Reg. An. v. 125). He,

however, does little more than quote the name, which was a catalogue name

of Megerle’s, mentions no species, and so far attempts to suppress it, that

he asserts that such very different species as ‘‘ tristis, lugubris, funesta’’ (now

forming the genus Morimus) “ offer the same characters”!!! The first de-

scription is really due to Serville, in Ann. Soc. Ent. de France, iv. 98 (1835).

The type P. pilosa (Dej.), Serv., had its name, I venture to think, most unne-

cessarily changed by M. Mulsant, because there is a Pogonocherus called

“pilosus.’ It so happened, however, that two years before Serville published

his description, Brullé had described another species under the same name.

This, therefore, retains the name, while Serville’s pilosa must be replaced by

Mulsant’s ‘‘ Solieri.’”’

Byse.

Characteres ut in Parmena, sed prothorax subquadratus, late-

ribus muticis et leviter rotundatis, et elytra breviter ovata,

The prothorax in Parmena, although somewhat variable, always

shows traces of the lateral tooth; the elytra, however, never rise

beyond the line of the prothorax, and are always elongate-ovate.

The curious little insect forming the type of Bybe is somewhat

intermediate in appearance between Parmena and Microcleptes.

Bybe parmenoides. (Pl. X. fig. 7.)

B. fusca, vix pubescens, nigro-setosa; femoribus basi et tarsis

Hab,—Sarawak.

Dark reddish-brown, almost without pubescence, but with

scattered black setose hairs ; head transverse in front, finely punc-

tured; lip short, pale rufous; prothorax closely and coarsely

punctured, scarcely broader than the head, the posterior border

narrower than the anterior; scutellum extremely minute, acutely

triangular ; elytra about three-fifths the total length of the body,

covered with very large approximate punctures, strongly rounded

at the sides, broadest at about the middle, then tapering rapidly

to the apex, which is rounded, the shoulders nearly obsolete ;

body beneath and legs chesnut-brown, with the bases of the fe-

mora and the tarsi reddish-chesnut ; antennz about as long as

the body, the third and fourth joints of equal length and about

twice as long as any of the following joints.

Length 2 lines.

The following genus is of somewhat doubtful affinity ; I insert

it provisionally at the end of the Dorcadionine :—

TRACHYSTOLA.

graciles, intermedii breviores; acetabula antica angulata;

femora vix incrassata ; tarsi subattenuati, articulo ultimo elon-

gato. Prosternum haud elevatum. Mesosternum dentatum.

M. J. Thomson places this genus in his “ groupe Mesosite,”

between Aderpas and Anamera,* (the latter, I conceive, belong-

ing to the Lamiine) ; the habit, however, the peculiar sculpture

of the elytra, and particularly the lobed base, together with the

short dense squamosity, so characteristic of the Dorcadionine,

seem to me rather to suggest the latter sub-family, notwithstanding

its humeral angles, and the possession of wings. There is an un-

described genus in the British Museum from North China,

which might, at first sight, be taken for a T'rachystola, but which

is also so suggestive of Phantasis (an African form of Dorcadio-

ning), that Mr. White has placed it in immediate connexion with

that genus. Admitting the difficulty of locating Trachystola for

the present, I have little doubt its true place will be with the Dor-

cadioning. M. Thomson’s species (7. scabripennis) is from Java,

and may possibly be distinct, at least a specimen from the same

country in the British Museum, if identical with M. Thomson’s

type, is sufficiently characteristic to be so considered.

Trachystola granulosa.

Black, opake, everywhere densely covered with a short brown-

ish squamosity; head rounded in front and at the cheeks, and

neither punctured nor sulcated ; prothorax transversely grooved

anteriorly, with five flattish tubercles on the disk, arranged 2, 1,

and 2 (the middle one. sometimes obsolete), stoutly spined at the

side; scutellum transversely subcordate ; each elytron with nine

rows of black shining granules, the inner row remote from the

suture, its granules oblong or linear, a few (6—8) granules on each

side of the scutelium, arranged in two rows, the second row from

the suture extending to half the length of the elytra, space be-

tween the suture and the inner row with two irregular lines of

Length 10—11 lines.

HypsELoMIN&.

The genus which gives its name to this sub-family is exclusively

confined to South America, and was generally supposed to be

synonymous with Hypsioma, Serv., until the difference was pointed

out by Messrs. Thomson and Bates. Hypselomus, Perty, is,

however, a somewhat aberrant genus, and it would therefore have

perhaps been better to have called the group Hypsiomine, were it

not that M. Thomson has a “ division” Hypsiomite limited exclu-

sively to the South American species. Mr. Bates places these

genera with Oncideres.

The principal character of this subfamily is the approximate

and almost contiguous position of the antennee at their base, a cha-

racter which, except in Hippopsine, is only occasionally met with

among the Lamid@. To this is generally added a long, stout, more

or less cylindrical scape, a trigonate form of elytra, which are

crested or otherwise raised at the base, legs of moderate length

with thickened or clavate femora, and tarsi invariably of equal

length or nearly so. Except in the South American genera, the

mesosternum is almost without exception elevated and produced, or

toothed. Among the Asiatic and Australian forms only four genera

have the prothorax unarmed,

None of the species of this sub-family are found in Europe, and

Acridocephalus, Chev., is the only African genus known to me that

can be referred, and that not altogether definitely, to it. All the

Asiatic* and one Australian genus are represented in the collec-

tion, which contains nineteen genera} and thirty-seven species.

Of the Australian genera, Zygocera, Callipyrga, Demonassa, and

Meton, are among the most prominent ; the last, alluded to above,

has a species from Asia.

* There is a form, however, from Northern India, described by M. Thom-

son (Arch. Ent. i, 294), under the name of Monochamus subgemmatus, which

appears to me to belong to this sub-family, and to be very nearly allied to

Pharsalia, and with difficulty distinguishable from it by any definite technical

characters. The antennz of the males are shorter and less setaceous, the scape

stotter, and the femcra narrower; the mesosternum is also prominently

toothed anteriorly. In my collection it has long stood under the Beene

name of Cycos. (See Proc. Zool. Soc. 1866, p. 244.)

+ Exclusive of Lelida (post, p. 257}, -which probably belongs to this as

family, though its true position is at present doubtful.

When I proposed Stegenus I stated that it differed from Achtho-

phora chiefly in its antenne, the first four joints being clothed

with stiff hairs instead of only the apex of the fourth. In other

respects it agrees so closely with Achthophora, that after a re-

newed comparison, I think it is desirable to unite them. Achtho-

phora alma has the prothoracic spine tolerably well developed ; it

is smaller in A. tristis, the type, and least of all in 4. dactylon, in

which it is scarcely noticeable. Mr. Newman considers that

A. alma may be only a variety of A. tristis, but the typical spe-

cimens, which are the only ones I am acquainted with, do not in

my opinion justify such a conclusion. A. dactylon, which is appa-

rently rare in Borneo, seems to be a common species in Penang.

The other two are from Manilla. My original specimen was en-

tirely of a dark brown, except the apex of each elytron, which

had a peculiar finger-shaped patch of buff, but all those from

Penang have numerous small very clear spots of yellow on the

elytra, and some indications of paler or more greyish spots else-

where, particularly on the prothorax.

These characters are drawn up from the three species collected

by Mr. Wallace. A nearly allied genus from Penang (Omocyrius)

differs in the oblong prothorax, the altered proportions of the

joints of the antenna, and the fourth and fifth being thickened

throughout in both sexes, the third also in the female is nodose at

the apex: in addition it has the shoulders produced as in

Otarionomus and Achthophora. So far as the individuals [ have

seen can be relied on, the males of 7’. Saunderst and T. tristis are

smaller than the females, but this is reversed in 7. Chevrolati. All

the species have numerous glossy-black granulations of varying

size on the basal part of their elytra, as well as a broad white

band on the cheeks, sides of the prothorax, and sterna,. A

female specimen from Batchian, which I cannot refer to any of the

above, although it approaches 7’. tristzs, has the scutellum equila-

terally triangular, not broadly truncate, or broadly rounded, as in

the other species.

The sole representative of this genus was originally described by

me as a “ Monohammus,” although at the time I ventured to suggest

a doubt ofits really belonging to that group. Monohammus, or rather

Monochamus, was, and is at this moment, a mere name, under which

Longicornia Maiayana. 235

many very distinct forms have been conveniently but unnaturally

placed. M.James Thomson has since proposed new genera for a

few of these, and further on I shall have many more to describe.

Such genera may be, and often are, very difficult to limit, but they

exist as categories of species, and when not solely founded on tech-

nical characters, they are an advantage to the real student. Of

course to those who would fain pursue “the royal road” they are

simply a bore. Otarionomus is a very distinct genus, and, as its

author bas pointed out, is very nearly related to Triammatus, and

this is still more evident since the discovery of Omocyrius. There

are certain discrepancies both between M. Thomson’s descriptions

and my own original one and that here given ; my original speci-

men, however, has a very different look from one of the magnifi-

cent insects now before me, and from which | have drawn up the

present article.

The type of this genus was referred by Mr. White to Cereopsius,

but the large head and smaller eyes, together with the form of the

prothorax, strongly constricted at the apex and base, and the

nearly central position of the spine, are at variance with the

characters laid down for that genus. The figure of this handsome

insect given by Mr. White does it very scant justice.

a few scattered punctures, deeply impressed with an irregular

transverse line before the spine and another behind it, the centre of

the disk irregularly corrugated ; scutellum broadly triangular, its

By the removal of Othelais and Etymestia this genus is now in-_

telligibly limited, although one of its species (C. marmoreus), from

its shorter legs and more elongate form, is somewhat aberrant.

One of the unpublished species, C. Saga (Dej.), has, however, the

elytra rounded at the apex,

Black ; space round the eye, sides of the prothorax, a long

stripe on each elytron, and body beneath, covered with a

whitish pubescence, a large spot on each side of the prothorax

anteriorly, and two spots on the stripe of the elytron (the foremost

sometimes divided) pure white, or, sometimes, sulphur yellow;

elytra sparingly punctured, the central portion of the disk nearly

head minutely and sparsely pubescent, with a raised vertical line

in front ; prothorax sparingly punctyred, entirely black ; scutellum

rounded posteriorly ; elytra remotely and irregularly punctured,

the black portions covered with short squamiform hairs, the

Hab.—Batchian.

Deep black, with a whitish band on the prothorax and two broad

snowy-white bands on the elytra; head covered with a greyish

pubescence and having a raised vertical line in front; prothorax

apparently impunctate, the anterior portion covered, except at the

apex, with coarse whitish hairs, forming a broad well-defined

band ; scutellum triangular, slightly rounded behind ; elytra as in

the last, but with rather narrower bands and the second one only

not extending across the suture; body beneath and legs with an

ashy pubescence ; antenne black.

This and the last are the only white-banded species in the genus,

and this is at once distinguished by the presence of an additional

band on the prothorax ; the lateral spine also is placed a little

more behind the middle.

round snowy-white spots on each elytron ; head with a somewhat

ashy pubescence in front; prothorax with a few remote punctures,

principally in the centre ; elytra slightly elongate, the first spot

midway between the base and middle, in a line with this trans-

versely and near the margin is a smaller one, which is probably

sometimes absent, the third spot is behind the middle, and the

In this and the two preceding species the transverse ridge,

formed by the strong constriction at the base of the prothorax,

has the little projecting point, found in all the species in the centre

of the ridge and therefore opposite the scutellum, bifid.

Sub-elongate, black, elytra irregularly marbled with ashy ; head

and prothorax with a thin ashy pubescence, the latter with five

callosities between the apex and the transverse ridge, which is also

somewhat interrupted so as to present the appearance of three

more callosities; scutellum triangular, ashy; elytra deeply but

sparingly punctured at the base, the ashy markings more or less

transversely zig-zag ; body beneath and legs with a thin ashy pile;

antenne reddish-brown, darker towards the apex.

Cereopsius privatus.

C. sub-attenuatus, fuscus, pube cervina tectus; prothorace inter

Hab.—Malacea.

Rather narrow, dark brown, covered with a fawn-coloured pu-

bescence ; head with a somewhat ashy pubescence, a few remote

punctures in front, lip fringed with ochreous hairs; prothorax

of nearly equal breadth at the base and apex, the transverse inter-

spinous ridge nearly obsolete, but with a little bifid prominence

opposite the scutellum ; elytra obliquely lineato-punctate, two or

three of the interspaces posteriorly forming slightly raised lines,

but uniting into one before the apex ; body beneath, legs, and an-

tennz with a thin ashy pile.

Length 5 lines.

This is rather a degraded form of the genus, but still preserving

all its characters, except that the disk of the prothorax is less

irregular, It, however, undoubtedly tends to obscure the line

between Cereopsius and Xoes.

The type of this genus was originally placed by me in Cereop-

sius, but the above characters preclude its being retained in that

group as now constituted. The two species described below are

very distinct, but O. virescens, in form and colour, has a marked

resemblance to Diallus subtinctus.

Black, finely pubescent, with snowy-white spots and stripes ;

head and prothorax impunctate, black, front and cheeks white ;

the prothorax with three white stripes on the disk, the lateral

stripe above and distant from the spine, and one on each side

beneath it, anteriorly on the disk a transversely impressed line ;

scutellum narrowly triangular, nearly entirely black; elytra

elevated at the base, slightly curved, irregularly punctured, with

numerous very distinct snowy-white spots, two considerably

larger than the rest on each side—one before, the other behind

the middle—the apex of each elytron deeply emarginate, and

terminated at each angle by a slender spine, the outermost being

continuous with a short keeled line ; body beneath black, shining,

the sides with whitish pubescent patches ; legs with a reddish tint,

thinly covered with an ashy pubescence ; antennz rather longer

than the body, dark ferruginous, the third and fourth joints at the

base, and nearly the whole of the sixth, white.

scattered punctures, three whitish stripes on the disk, the lateral

one passing through the spine, another stripe below it, the spine

long and very slender, no impressed line anteriorly ; scutellum

subtransverse, truncate posteriorly ; elytra longer and narrower

than in the preceding, less elevated at the base and less convex,

each with four, five or six Jargish dull-white spots at the side,

the one at the shoulder being sometimes broken up into two or

three, the apex of each elytron slightly emarginate, comparatively,

and terminated at eachangle by a short broad process, the outermost

being only slightly continuous with a keeled line, which extends

nearly to the base of the elytron; body beneath dark chesnut,

shining, the sides partially pubescent; legs and antenne pale

A sufficiently distinct genus, easily distinguished from Cereop-

sius, as well as from Othelais and Otroea, which it also resembles in

habit, by the short third joint of the antenne. The prothoracic

spine, although directed backwards, is not recurved as in Othelais.

The cicatrix on the scape is smooth and shining. The species are

tolerably homogeneous, rather below the middle size and spotted

with white on a dark ground. ‘

median ; scutellum quadrate, edged posteriorly with white; each

elytron with two slightly raised lines, the inner more marked and

extending to the apex, and about twenty spots, irregularly ar-

ashy hairs ; prothorax rather strongly punctured, with three white

bands, one at the apex and one at the base, both well marked, the

intermediate one between the lateral spines indefinite; scutellum

nearly triangular; elytra irregularly punctured, one elevated line

on each, the ashy spots fewer than in the preceding ; body beneath,

legs and antennz with a coarse ashy pile.

apparently impunctate, covered with whitish hairs; prothorax

rather strongly punctured, a short transverse slightly-raised ridge

in the middle, one central and two lateral greyish stripes; scu-

tellum truncate posteriorly ; elytra coarsely punctured at the base,

a single raised line on each posteriorly, the basal half with five

greyish spots, one common at the apex of the scutellum, and two

on each side, the apical half with about twelve white spots, two

common to both elytra, but in all probability the number and size

will be found to vary; body beneath black, shining, the sterna

and sides of the abdomen with an ashy pile; legs and antenne

brownish-testaceous, with a pale-greyish pile.

This genus approaches Othelais and Diallus in habit and in

many of its characters; from both it is distinguished by the short

straight spine of the prothorax, and the broadly-transverse joints

of the anterior tarsi. The three species described below are very

distinct in coloration, but the sculpture is very similar, especially

of the first-two. The second antennal joint is more than usually

elongate in this genus.

This handsome genus will be readily recognized, at least among

those in this collection, by the obconical form of the prothorax,

which is without any trace of the lateral tooth, and by the long

setaceous antennz (varying however from twice to four times

the length of the body in the same species) as contrasted with

Achthophora.

The characters of this genus, as well as the species that com-

pose it, have nothing about them very decided. Nevertheless the

genus is a tolerably natural one, and the species very distinct. I

am not, however, acquainted with the type (P. Malasaica), but I

have received from M.J. Thomson P. gibbifera, Guér.,* to which

it appears Monohammus ? agenor, Newm., is to be referred, and

with this I have little difficulty in connecting the species de-

scribed below as congeners. P. cincticornis is a female specimen

and may possibly be P. Malasaica, Thoms., but that author omits

all mention of the antenne. ‘The colours of these insects are a

mixture of various shades of grey and brown, and sometimes

ochraceous ; and the elytra have each two raised lines, which are

more prominent posteriorly.

I have seen wants the last six joints of the antenne, but the

fifth joint is longer than the fourth, and this again longer than

the third; the contrary of this occurs in the female, from which

sex only M. Thomson appears to have drawn his description.

In characterizing this genus in the work above quoted I placed

it between Monochamus and Dystheta, but on examining it afresh

I think its affinity (as well as that of Dystheta) is more with the

present sub-family, particularly in regard to its clavate femora.

None of the species, however, with which we are acquainted,

seem suggestive of any affinities; and the genus, like many others of

this and other groups, can only be regarded as somewhat aberrant.

The genus has two well-marked species in Australia (M. Dig-

glesii, Pasc., and M. tropicus, Pasc.).

M. J. Thomson has separated this and two other species from

Zygocera, to which I had referred them, to form three genera.

This, however, is the only one which occurs in the Malayan

Fauna, and is distinguished from Zygocera by its transverse face

and the anteriorly-dilated prosternum extending more or less

in front of the anterior coxe. The latter character it has in

common with Disterna—another of the three genera alluded to,—

and from this it scarcely differs, except in the form of the head

anteriorly.

The following genus, in the great length of the antenne and

the short feet, seems to approach Hippopsis; but the shortness

of the sterna and the cicatricose scape forbid any association in

that direction; there is an analagy, at least, between this genus

and Otroea, in the breadth of the anterior tarsi, and the approxi-

mation of the antennary tubers is significant of its probable affinity

to the Hypselomine.

LaMINe,

After a careful examination I have come to the conclusion that no

sufficient differentiation can be made between Lamiine, Monocha-

mine and Gnomine, and that to obtain anything like a satisfactory

set of characters it would be necessary to form a large number of

groups, or, as we would call them for the sake of uniformity,

“ sub-families.” It may seem a violation of all our ordinary ideas

of natural affinity to place Gnoma with Petrognatha, Cylindre-

pomus with Tragocephala, or Lamia with Gerania, yet such are the

extreme varieties of form and so graduated the characters by

VOL. III. THIRD SERIES, PART IlI.— SEPT, 1866. s

258 Longicornia Malayana.

which we attempt to fix them that it is only a choice between the

combination of the most heterogeneous genera, or the addition of

numerous sub-families,* which would also, many of them, contain

exceptional forms. With few exceptions this evasive variation

seems to be the rule throughout the Longicornia, and this makes their

classification so difficult. By strictly limiting the more obviously

allied species to the same genus’ the difficulty is obviated in

them, but we should lose some of the advantages of classifica-

tion if this principle of homogeneity were to be carried into the

higher groups.

To give any but the most general remarks on this sub-family, in

the extensive signification which is here given to it, would be

almost impossible ; nearly every extreme of colour, form and size

are represented,—some are among the giants of the insect class,

some are remarkable for their long antenne, or their short legs,

or for a combination of both. The majority of them, however,

have a form of which the common European Monochami will give

a central idea, from which the aberrant genera depart by gradual

modifications, not always, indeed, without a break.

The affinities of the Lamiine are very decided. To Hypselo-

min@, especially to such genera as Triammatus, Omocyrius,

Pharsalia and others, there is the strongest resemblance ; Lamia,

Morimus, &c., recall the Dorcadionine ; and Nemotragus and

Anauxesis lead by Megacera to the Hipposine.

The geographical distribution of the Lamin@, when we consider

their numbers, may be said to be almost exclusively confined to

the African, Indian, and Malayan regions. Europe and Ame-

rica, north of Mexico, have only the genera Monochamus, Mori-

mus, Lamia, and Plectrodera ; the two principal genera of tropical

America are T'enioles and Ptychodes ; Monochamus. again and

Batocera are the only exponents in Australia, and the presence

of the latter genus, except as introduced, is doubtful, although

it may perhaps be found to occur in the extreme north of that

continent. Z'hysia, Oplophora, and a few other genera, occur in

India and China. The headquarters of the sub-family are un-

doubtedly the Malayan islands, but if we take the African Zon-

gicornia, and compare the amine with the other sub-families,

they will be found to be by far the predominant group.

* I would particularly mention the following genera as the types of some

of these groups :—Petrognatha, Ceroplesis, Tragocephala, Sternotomis, Phryneta,

Ancylonotus, Gnoma, Olenecamptus, Nemotragus, &c. In M. J. Thomson’s

*« Systema Cerambycidarum”’ many of these form “ divisions.”

Longicornia Malayana. 259

The African genera are, however, very distinct and have scarcely

anything in common with the Malayan.

One hundred and ten species occur in the Wallacean collection,

which I have distributed into twenty-eight genera. In the following

tabulation it has been necessary to adopt characters some of which

M. de Castelnau includes Anoplostheta and Plectrodera in this

genus, and consequently he is unable to take advantage of the

very decided characters afforded by the antennz and elytra, which

at once distinguish Batocera from all the other genera in this

sub-family. Batocera rubus, Lin.,* the type, is found all over the

East Indies, and extends from the Isle of France to Australia, (in

the latter country, however, probably introduced, as it has been in

Europe), but, oddly enough, it does not seem to have been met

with by Mr. Wallace. The genus is one of the finest among the

Coleoptera, B. Wallacet sometimes measuring eleven inches in

length from the hind tarsi to the extremity of the antenne ; but at

the same time, owing to various modifications of colour, it is one

of the most difficult in regard to the differentiation of the species ;

in many cases it is impossible to distinguish them without the aid

of a suite of specimens. The species are mostly found on fallen

timber ; and they fly about in the evening as well as in the hottest

sunshine.

* M. Kaup (Einige Ceramb. &c.) considers the Lamia rubus, Fab., to be

distinct from the Linnean species, and has named it Ba/ocera Wieneckii.

intervals ; antennz slightly pubescent, apices of the joints from

the fourth to the eighth with two short spines, the ninth slightly

angle terminating in a moderately short spine, the outer angle

only slightly produced, not spinous; body beneath pubescent,

Dark brown, witha dull yellowish-grey pubescence; scape (in the

males) roughly punctured at the base, the intervals rising into

short irregular folds ; other characters as in B. octomaculata, but

the third joint of the antennez is considerably longer in both

sexes, and, in what are apparently the normal specimens, there is

only one large spot in the middle of each elytron, with perhaps two

or three mere points, not always the same number on both sides ;

the exterior spine at the apex is as large as the sutural in the

male, and is only a little less so in the female; the fore and inter-

mediate legs are also more robust and longer than in the preced-

ing.

the latter less pubescent ; antennz more decidedly punctured and

less scabrous, the apices of the joints somewhat enlarged but not

produced ; scutellum with a slightly silky yellowish-grey tomentum;

elytra rather elongate, cuneate, or with the sides straighter and

narrowing more rapidly posteriorly, each with a sunken irregular

I have only a single specimen of this species, but its metallic

Length 33 lines.

The last antennal joint of the female is in my specimen thickened

and somewhat falcate. This species is best distinguished from

the others in this section of the genus by the white spots on the

elytra, and the absence of the lateral stripe from the head and

prothorax.

Allied to the preceding, but there are no white spots on the

elytra, which are closely covered with a short whitish pubescence,

except at the base and sides, which are ochraceous; numerous

small punctures in patches are scattered over their surface, the

punctures being very distinct notwithstanding their small size, and

in nowise hidden by the pubescence; apices obliquely truncate,

the sutural angle rather broad and slightly produced; body be-

neath and femora luteous, covered with a very regular and delicate

fawn-coloured pile, rest of the legs darker; sides of the sterna

with a broad white lateral stripe ; antenne incrassated at the apices

of the joints and shortly bispinous.

region and sides with an ochraceous tomentum, the interval

glabrous and glossy black, more or less spotted with snowy-white ;

sometimes the spots are nearly connected throughout, forming an

irregular stripe from the base to the apex, or (passing through many

stages) theyare nearly obsolete, the ochraceous tomentum extending

more or less over the whole, or the tomentum is nearly absent alto-

gether; body beneath with a greyish pubescence, the lateral stripe

extending from the prothorax to the end of the abdomen; an-

tennze sometimes nearly three times the length of the body, very

scabrous, the apices of the joints thickened, strongly produced on

one side, and furnished with two or three stout spines.

This is probably the finest species of the genus; it is very

variable in size and colour, but in all cases preserves a certain

distinctive character not to be mistaken.

more or less crowded together, forming large irregular patches,

these points at the base are chiefly composed of the usual granular

projections which gradually lose this character and become at

the middle little transverse impressions and towards the apex

ordinary punctures, but in all cases surrounded by a slight

glabrous space except along the sides, where the pubescence is

darker and more condensed; apices truncate, each angle ending

in a strongly-marked spine; body beneath and legs tawny, no

My description, like M. Thomson’s, is made from a female ;

There is in the collection the female of another and apparently

distinct species, which is uniformly covered with a thin yellowish-

grey pubescence, has the apices of the elytra acutely bispinous,

and the antennz ringed with ashy. It stands under the provisional

name of Batocera Claudia in my cabinet,

The two examples of the type of this genus in my collection,

the only ones I am acquainted with, appear to be females, so that

the character of the male antennz remains to be ascertained. In

the female, however, they are perfectly mutic, except the minute

spines at the apices of some of the joints, and in this respect, as

well as in the non-spinous shoulders, the genus differs essentially

from Batocera. Mr. Wallace informs me that the spots on this

insect when alive were of the richest yellow ; one of my specimens

still preserves much of this colour, in the other they are pure

white. These spots are formed by a singularly dense and matted

pubescence.

length in all the legs. The nearly straight anterior tibia and

more or less elevated mesosternum are also to be remarked in

conjunction with other characters. Two very fine and noble

species, but varying very much in size, are comprised in this genus ;

three others, which I have also referred to it, must for the present

remain somewhat doubtful, as I have seen only one example of each,

and these are so remarkable that I have given a figure of each.

This fine genus seems to have been misunderstood by authors,

and another set referred to it, apparently in ignorance of Serville’s

type, while the more recently described species have been brought

together by M. J. Thomson under the name of Rhamses. The

principal characters distinguishing this genus from Monochamus

are the long anterior legs of the males, the tibiz of which are

denticulated along the lower edge and armed near the apex with

a strong tooth. With regard to the armature of the prothorax,

Longicornia Malayana. 277

this is one of those genera in which the lateral tooth seems to be

only of specific importance, as it varies from a mere point to a

well-marked spine. All the species have the elytra granulate at

the base, and the punctures rapidly disappearing towards the

apex. The females as usual have fuller and more parallel elytra,

with antenne rarely more than a half as long again as the body,

while in the males they are often more than three times as long.

If these characters apply to the male the genus is perhaps a

good one; otherwise the few specimens I have seen, as well as the

figure given by M. Blanchard, might very well pass for females

of aspecies of the previous genus. They are particularly like the

female of Pelargoderus Arouensis.

Longicornia Malayana. 281

Olivier described and figured the type species of this genus

many years ago, but until Mr. Wallace sent it to England with

two new species, it remained otherwise unknown. The genus is

remarkable for the almost perfect flatness of the disk of the

elytra, which is suddenly bent down at the sides at a right angle

(less marked however in P. lima), and the sharp ridge thus

formed is furnished with a row of short sharply-pointed spines,

and at. the sides or above with more spines. These species

appear to be very rare; I have only seen them in my own col-

lection.

Reddish-brown, closely covered with a scale-like reddish-grey

pubescence, and with small partially erect hairs scattered amongst

it; head dark brown behind the eyes; prothorax very irregular,

with three especially well-marked tubercles, coarsely granulate,

the granules dull black, nearly concealed by the pubescence, and

with a deep preapical transverse groove ; scutellum small, angular,

transverse; elytra very flat above, somewhat concave between

the base and middle, a few spines on each side of the scutellum

forming a kind of crest, and five or six on each side in a line with

the discoidal angle, which is furnished with about a dozen of

them, another line of spines on the declivity of the side and a few

at the shoulder ; the discoidal angle, terminating abruptly beyond

the middle, is succeeded by a large, somewhat triangular, brown

patch, which extends nearly to the apex; body beneath and legs

with a close brownish-yellow pubescence, speckled with single

hairs of a paler colour scattered amongst it as on the back; the

legs, especially the femora, are also marked with numerous short

nitid raised lines, in some parts mixed with granules; this mixed

kind of pubescence, together with the lines and granules, are also

found on the three basal joints of the antenne, but on the re-

mainder the pubescence is uniformly close, and greyish on a pale

testaceous-brown surface.

This specimen is a female, and compared with the female of the

preceding species it differs in its larger size with much larger

elytra proportionally, duller pubescence with less scale-like hairs,

the elytra slightly convex along the middle of the flattened part,

the discoidal angle less prominent, with fewer spines generally,

and the legs and antennz with fewer and less prominently raised

lines, with no admixture of granules, except perhaps a few on the

scape.

a whitish pubescence faintly clouded with grey, the sides much

darker; head and prothorax speckled with a few glabrous black

spots, the latter less rngose and without the preapical transverse

groove of the other species ; scutellum small, sub-scutiform ; elytra

finely punctured, the flattened part slightly convex along the

suture, with fewer spines than P. scabrosus, and without the brown

patch, the outer spine at the apex produced ; body beneath and

legs more sparsely pubescent, brownish-grey, the latter and the

large eyes, the lower lobe being nearly contiguous to the mouth,

and its toothed mesosternum. ‘lhe three species described below

oblique brownish band, shading off insensibly behind, beginning

near the shoulder and terminating at the suture about the

middle, a few minute granules anteriorly, and here and there a

pale grey setulose hair, the tooth at the shoulder small and trans-

verse, the spine at the obliquely truncated apex produced; body

beneath chesnut-red, with a coarse grey” pubescence, the pale

the base of the lateral spines, the humeral tooth very small, the

blotch at the base transversely reniform, the apex broadly truncate

with the outer spine short, and the scape rough from the presence

of small, mostly transverse, raised lines.

The following species, known in collections as ‘ Leprodera

pleuricausta, de Haan,’’ and described under that name by M.

Thomson, has been recently separated by that author as the type

of this genus, chiefly on account of its shorter antennz. To this

may be added that the head is considerably broader in front and

not dilated beneath the eyes, the lower lobe of the eye is smaller

and oblique, and the elytra have basal crests. The original

examples were from Java.

Leprodera plagiata, Thoms., on account of its narrower head

and oblique eyes, scarcely enters into this genus as it is here

defined, yet these are the characters which principally cut it off

from Epicedia ; as a secondary character it may be mentioned

that the elytra are without basal crests, and therefore on the

whole it will better fit into the present genus. All the species have a

dark brown or blackish derm, uniformly covered with a greyish or

fulvous-grey pubescence, and the brown bands and spots are com-

posed of a very dense cloth-like pubescence without any gloss.

M. Thomson in his ‘‘ Essai” places this genus after Leprodera,

but in his “ Systema” he puts it with the “ Gnomite.” The species

briefly described by Hope (penicillata) was simply referred by

him to “ Lamia,” and seems to have been the type of M. Thomson’s

genus. One of Mr. Wallace’s specimens from Flores has a more

uniform colour than the others, all of which appear to have been

taken in Borneo and to belong to Olivier’s species. Another

species, described by myself (Journ. Entom. i. 344), is sufficiently

distinguished by, inter alia, the greater comparative length of the

third, fourth and fifth joints of the antenne.

The Malayan species of this genus have a strong general

resemblance inter se, different from its European and American

exponents. I have sought in vain, however, for any character to

distinguish them. They appear to vary greatly within the narrow

limits of their characters, and it is very difficult to say how far

some of these may be permanent. As it is I have here and there

“Jumped” several individuals under one species that appear to

have a primd fucie specific position, They may be divided into

sections according to the character of the apices of their elytra ;

there seems reason, however, to believe that even here there are

certain modifications in the same species, so that this character can

only be relied on approximatively.

A specimen from Aru, which may be the female, differs

in having a much less silky pubescence, and the apices of the

elytra show no vestige of a tooth. I have seen a similar spe-

cimen in the British Museum, ticketed ‘“ MZ. holotephrus, Bois.,”

but that author describes the prothorax as having “plusieurs

This genus is separated from JMonochamus on account of its

widely-placed antennary tubers, large eyes, and toothed meso-

sternum; and these characters, taken together, separate it also from

all other genera of Lamiine proposed in this work. The type was

long ago described by Olivier, but does not appear to have been re-

cognized by subsequent authors, except Fabricius, who gave it

another name ; it is very variable in colour. D. lugubris and D.

_impluviatus are described from single specimens, and it is possible

that similar variations may occur in them. JZonochamus ambi-

genus, Chev., also belongs to this genus.

Black, nitid, varied with white, grey, or ashy, depending

on a very close-set pubescence, generally well limited, while

the black portions havea very short and scattered or almost ob-

solete pubescence; on the vertex are three white lines which meet

in front, and these are continuous with three corresponding

lines on the prothorax ; scutellum semicircular, black or white, or

with a white border only; elytra with irregular scattered punc-

tures, the shoulders granulate, the white parts varying in extent

or becoming grey, but always having a transverse direction ; the

normal style is perhaps based on two irregular white bands, thus

dividing the black into three portions, the bands nearly disappear-

ing or gradually extending so as to reduce the black to a few

spots in many examples; body beneath with a thin pubescence,

grey or ashy, the abdominal segments with one or two light-

coloured spots on each side, which are sometimes obsolete ;

iegs with a grey or ashy pubescence ; antennz blackish, in the

males about half as long again as the body, sometimes ringed

elytra with scattered punctures almost hidden by the pubescence,

a few granules on the shoulders, base dark brown with a few

The prothoracic spine in this genus is reduced to a mere point ;

the legs are equal in both sexes; and the claw-joint is of large size,

but this seems to be a character of less importance among these

genera than it is in other groups. In other respects the genus is near

Monochamus, except that the head is more quadrate in front.

criminate so far as regards the males, and the females, as it appears

to me, are absolutely undistinguishable. Scarcely any of the

characters appear to be permanent, and all the specimens, so far

as I have noticed them, may be divided into two categories, each

of which might be conveniently considered to represent one very

variable species—Gnoma giraffa, Schreib., representing the long-

necked black category, and Gnoma sticticollis, J. Thoms., the

shorter-necked brownish and spotted category. It will be very

difficult to ascertain what are the really permanent species with

our present data. The following descriptions apply exclusively

to the males; the females have always shorter necks, legs and an-

tennze, and the elytra broader and more parallel, and often more

varied with white than the males.

Olenecamptus is a well-marked genus, at once distinguished by

its short rough scape without a cicatrix, in conjunction with its

short posterior legs. A remarkable and probably dimorphous

variety has been separated from O. bilobus by M. Chevrolat, on

account of the inner edge of the fore tibiz being minutely ser-

rated, under the name of O. serratus. I have similar examples

from Timor and Flores. The inner edge of the antenne is

sometimes serrated in the same way. This species has a very

wide range, being found all over India, Ceylon, Java, &c., and

has been also reported from Australia.

An elegant genus, only known before Mr. Wallace’s researches

by a single species, and at once distinguished from any of the

preceding, except Olenecamptus, by the non-existence of a cicatrix

of the posterior legs, which, except in one species, are Jonger than

the anterior, an unusual character in the sub-family. The species

vary greatly in colour, but are all finely pubescent.

legs and antennze than the male, but otherwise scarcely differs.

a specimen in the collection of Bosc. As I am not aware of the

existence of any figure of the species, I have given one of the male.

ONocEPHALINE.

This sub-family exactly accords with M. J. Thomson’s 14th

‘groupe,’ as defined and limited by him in the ‘ Essai” (p. 120),

so far as its members were at that time known. It was there

composed of the four genera Gryllica, Pachypeza, Ischioloncha

and Onocephala. In the more recent “Systema” he makes it a

“division” of his ‘ groupe” Hippopsite, retaining of the above

only Onocephala, and adding two new forms—A fossa and Apechthes.

The form and position of the head is the most salient character

of the Onocephaline ; in the typical genus Onocephala, it is

rather large, produced and contracted above, so that the antennary

tubers are nearly or quite contiguous, dilated and prolonged

below the eyes which are small in proportion, and is bent in-

wards so that the face is more or less ina line with the under

surface. ‘The antenne vary in length, but they are generally

either pilose or fimbriated beneath, with the scape almost perfectly

cylindrical and without a cicatrix ; the legs are either of moderate

length, or so short as not to extend beyond the extremity of the

body; the tarsi are always short, with the claw-joint usually of

remarkable size. .

This sub-family appears to be confined to tropical America

and to the Malayan region; in Mr. Wallace’s collection it is re-

presented by a single individual, which, I am sorry to say, is in a

very poor condition, and it is only because of its importance as

the sole representative of its sub-family that I have noticed it.

Besides several genera described by M. J. Thomson, but un-

known to me (except Afossa), and some of which may probably

prove to belong to this sub-family, I have two or three unpub-

lished forms which I include in it; I think also that Mr. New-

man’s genus Hpaphra from Manilla may also be referred to it,

although of a somewhat aberrant character.

Hiprorsinz.

No other sub-family of Longicorns presents a head so peculiar

in its form and direction as the more typical members of the Hzp-

popsine. In these it is of a conical shape, and, as a cone, porrect ;

the upper line forms the vertex and the lower the face, the apex

bears the antennz, which are almost or quite contiguous at the

base, and the eyes are most abnormally placed at some distance

from the insertion of the antenne. But, as usual, these pecu-

liarities shade off in the different genera, so that at last we are

led rather by general resemblance than by any definite characters

to decide on their affinites.

The Hippopsine lie directly between the Onocephaline and

Saperdine ; the former sub-family shows the same tendency to

the horizontal position of the head, although in a less degree, but

always has the eyes in the normal position, a more robust form, and

the pro- and meso-sterna shorter, so that the anterior and inter-

mediate coxe are more or less approximate, while in the Hippop-

siné these conditions are reversed. The relations of the Hip-

popsine with the Saperdine will be noticed further on.

The members of this sub-family are found all over the world,

except Europe,* but are apparently not very numerous either as

to species or individuals. From Australia, indeed, we have as

yet only a single exponent of the group, Hsszsus, recently de-

scribed by me in Proc. Linn. Soc., Zool., ix. 90. The number

of species in Mr. Wallace’s collection is only five, distributed into

three genera.

This genus differs from Hippopsis only in the contiguity and

direction of the antennary tubers, and in the eyes being situated

at a little distance from the base of the antennz, a modification

which we find still further carried out in Tetraglenes and other

genera. Of the three species described below it might perhaps

have been more natural to have made A. montana the type of

a separate genus, as it has peculiar wedge-shaped elytra and

longer legs.

Mr. Newman says that this is the only insect he has seen ‘“ pos-

eye being apparently independent of the other three.” This is

not strictly correct, as a fine line may be distinctly traced evidently

connecting the two lobes. That these lobes should be placed at

a considerable distance from the base of the antennz is a more

abnormal arrangement. In a closely allied genus—Lucomatocera

—the upper lobe is directly joined to the lower, a slight indentation |

marking the point of union. In Euthuorus and Spalacopsis, the

upper lobe is wanting ; while in Dorcasta and Aprosopus the eyes

have nearly come back to their normal form. All these genera

are clearly allied. The species described below differs, inter alia,

from T. insignis, a species from Hong-Kong, Malacca, and Manilla,

in its narrower form, and in the apices of its elytra being straight,

not turned outwards.

These characters are drawn up from a specimen kindly sent to

me by M. Thomson under the name of Pothyne Malasiaca, which

differs somewhat from the description of his P. variegala. The head

is not much inclined in this genus, nor is it produced at the base of

the antennary tubers; in these respects it may be considered to

approximate to the Saperdine, to which perhaps it might be more

desirable to attach it. M.J.'Thomson’s species apparently differs

from the one described below in its “elytra obsolete punctata.”

SAPERDINE.

Saperda was one of the few genera formed by Fabricius out of

the old Cerambyx, in which Linnzus, now exactly 100 years ago,

had included all the Longicornia known to him, except Leptura and

Necydalis.* The only character, however, which had a real exist-

ence in differentiating Saperda from Lamia—another of the Fa-

brician genera—was the unarmed prothorax of the former as con-

trasted with the spined one of the latter; and chiefly on this

character M. Muisant in 1839 divided his ‘‘ groupe Clinocépha-

lides” (= Lamiide) into two families “ Lamiens’’ and ** Saperdins.”

adopting this division, distinguishes the former principally by their

clavate femora ; and being thus obliged to admit Monochamus,

which has nearly linear femora, into the Saperdine, he attaches a

secondary importance to the prothorax. Both these authors deal

with limited local faunas, but tested in a broader field the absence

or presence of a spine or tooth on the prothorax is a far more

valuable character than the clavate or linear femora.

The sub-family, as it is here limited, very nearly agrees with

the Saperdite vere of M. J. Thomson’s Systema; but with the

addition of Serixia, which that author has arranged with the 4m-

phionychine, notwithstanding that it has simple claws. Whether

the Agapanthiine should be maintained as a distinct sub-family,

* Syst. Nat. ed. xii. The first species of Leptura, however, is a Donacia,

and all the Necydales but three are Heteromera.

328 Longicornia Malayana.

I must confess appears to me at present to be doubtful. M. Léon

Fairmaire treats them as a distinct group, but if the subordinate

divisions of the longicorn families were to be elaborated in the same

way throughout the whole of their extent, several hundred such

groups would be necessary, and I am not sure that this may not

be found to be the most natural arrangement.

The leading characters of the Saperdine are as follows :—the

intermediate tibize are very slightly or not at all emarginate, and

never furnished with a tooth as in the more typical Lamiide ; the

prothorax is cylindrical and unarmed; the femora are linear or

thickened in the middle, rarely: clavate; and the pro- and meso-

sterna are simple. The head also is generally rounded in front,

and not exserted ; the antennz are of moderate length, sometimes

however very long, setaceous, and distant at the base; the feet

rather short; the body compact and often slightly depressed, and

the abdominal segments of unequal length. . They are distinguished

from the Obereine and Amphionychine by their simple claws, never

appendiculate or bifid; and from the Hippopsine, to which many

of their genera approximate, by the distant bases of their antennz.

It is sometimes difficult to distinguish some of the Apomecynine

from the members of this sub-family, but the former often show

traces of the prothoracic tooth which are not present in the Saper-

dine.*

The genera and species of Saperdine are numerous in the north-

ern temperate region of both the old and new worlds. In the

tropical portions of America, Amillarus is its only exponent, and

this in Chili is replaced by Emphytecia. In Africa we have

Eunidia, Syessita, Chariesthes, &c. In Australia at this moment

they are entirely unknown, and this fact affords another proof of the

striking dissimilarity that exists between its beetle-fauna and that

of the Malayan region, as Mr. Wallace’s Collection alone contains

thirty-five species, divided into eight genera. It must be observed,

that the character drawn from the absence of emargination of the

intermediate tibiz is not absolute, but that a slight break in the

continuity of the exterior edge is sometimes visible ; as it is, the

character serves to separate into two very natural categories the

genera of the Malayan members of this sub-family, the first four

having, moreover, a graduated approximation to the preceding sub-

family, and the remainder to the Astatheine, which follow.

* On this account I refer Zygrita to the Apomecynine, where indeed M.

J. Thomson originally placed it, rather than to the Saperdina, to which that

authority has referred it in the more recent “ Systema.”

With its approximate antennary tubers this genus forms a pas-

sage to the Hippopsine, from which it essentially differs in its

normally long and stout legs. The mesosternum, however, is

much longer than obtains in the ordinary Saperdine, and it must

be considered a rather unsatisfactory member of this sub-family.

In the work above quoted M. J. Thomson places this genus

near Oberea, but in the more recent “Systema” (p. 94) he forms

it into a distinct ‘‘ groupe,” putting it directly before his “* Hippop-

site.” It is certainly not to be considered a legitimate member

of this sub-family, but unless we adopt it as the representative of a

distinct group, I do not see that it can be better placed. It is

the genus Eusebis of Dejean’s Catalogue.

The affinities of this genus are not very evident. The linear

antenne with the white apical or sub-apical joints show an analogy

with Nyctimene, but the legs are of the normal length and the

tarsi are very different, in the latter respect resembling Seriwia

and Xyaste, near which it might be perhaps most naturally

arranged.

M. Guérin- Méneville in his ‘‘ Iconographie” (p. 245) points out

two or three characters by which this genus is distinguished from

Astathes, perhaps quite enough, according to the usual practice, to

fix him as the describer of it. As, however, there is no connexion

between the two genera, and M. Guérin’s remarks were not in-

tended to be supplemented by any future description, it does not

seem to me desirable that such a style should carry with it the

same rights of priority accorded to a real attempt to characterize

a new genus, and I have therefore referred to M. J. Thomson, who

has given a full account of it, as the true authority for the genus.

At the same time it is necessary to remark that his ‘* Entelopes

Wallacei, Pascoe,” is the common E. glauca, a very distinct spe-

cies, but why it is named “ glauca” is not evident; M. Guérin

says of it in his description “sans poil ni duvet,” but all the

species are covered with very delicate short scattered hairs. I am

unable to agree with M. Thomson when he describes the anterior

coxe as being transverse. LEntelopes is a beautiful genus, now

consisting of five species, one of which from Penang (E. similis)

I have recently described in the Proceedings of the Zoological

Society (1866, p. 255).

In the Journal of Entomology (i. 354) I have proposed to unite

Tolea to Serixia, the slight differences in the characters of the few

earliest discovered species not being sufficiently constant to warrant

their separation since so many more have been made known. M.

James Thomson in his “ Systema,” however, not only maintains

their distinctness, but places them in two different ‘“ groupes.”

The species vary considerably in size and coloration, and in the

comparative length of the antennz; and the head appears to be

much larger in some individuals than in others of the same species.

They have nearly all a fine silky, mostly. pale, pubescence, varying

or black, derm. On the prothorax there is a kind of sharp lon-

gitudinal elevation in the middle terminating'posteriorly just before

the base in a slightly abrupt point. The same character occurs

in Entelopes and Xyaste. Besides the species described below

there are a few specimens from Waigiou, Bouru, Sarawak and

Sumatra, which are very close to some of these, but cannot at

present be satisfactorily referred to any of them.

independently of the strange crest which it bears in front, and

which, even if it be generically characteristic, is perhaps only an

ASTATHEINE.

The only author who has paid any attention to Astathes and its

allied genera, M. J. Thomson, in his earlier work (Arch. Ent. i.

p- 45), formed of them a “ groupe” apart, named Tetraophthalmites,

to which, however, he also attached Tetraopes, Tetrops and Tetra-

glenes, on account of their divided eyes. In the “ Essai” (p. 66)

they formed a “division” of the ‘“sous-groupe” Apomecynite,

under the name of Tetraopesite, with the addition of the genus

Phea. In the more recent “Systema,” (p. 117) they became a

** sous-division”’ of the Obereit@, which is itself a * division” of the

“groupe” Amphionychite. With the exception of Serixia, which

I have already referred to the Saperdine, and Cleonaria, which is

unknown to me, this subdivision corresponds with the Astathene

as here limited.

The most remarkable of the characters of the Astatheine con-

sists in having the metasternum projected forwards between the

intermediate coxze, so as to cover more or less completely the

ventral surface of the mesosternum—the vertical portion only

being visible. Unfortunately this character is present only in

Astathes, Eustathes and T'ropimetopa,* and it disappears entirely

without any gradual modification in the remaining genera. Ano-

ther character is the broad lobe found at the base of each of the

claws; these appendiculate claws show themselves again in the

Phyteciing. ‘There is also anotber structural peculiarity to be

noticed in the mentum and lower lip. These two are closely

connected, so that it is difficult to trace any line of demarcation

* And in the African genus Ecphora.

348 Longicornia Malayana.

between them; together they form a narrow, parallel, somewhat

quadrangular organ, the two lobes of the lip united, and at their

junction presenting a strongly-marked keel or rib, The labial

palpi arise from two deep approximate depressions nearly mid-

way, which may perhaps be taken as the line between the mentum

and labium.* It may be also remarked that the anterior coxe in

the more typical genera are globose, passing only a little beyond

their cotyloid cavities.

‘Except Lephora, which is limited to a single species, the whole

of this family are either Malayan or Indian, not many, however,

extending beyond the former region. They are generally found

flying or rather “ floating slowly” over newly fallen timber. Te-

traopes, an American genus, sometimes referred to this sub-

family on account of its divided eyes, | regard as a member of

the Amphionychine.

tasterno omnino tectum.

The type of this genus, 4. perplexa, Newm., is a Manillan in-

sect, and is the only species known to me in which the prothorax

is strongly toothed; in all the others there is merely a tumidity,

which in some cases is very prominent, including a large part of

the side; it is also one of the few species in which the lines on

the elytraare scarcely or only slightly raised, although their places

are indicated by the absence of punctures, and sometimes of a

very delicate line. All the species have a glossy derm clothed

with short setose scattered hairs, but the coloration is often a

little uncertain. Astathes perplexa, for instance, generally uni-

colorous, has sometimes a large violet spot on each elytron; and

in others the blue or violet varies in extent, or becomes purplish.

Nevertheless the disposition of the colours, which are mostly a

combination of yellowish-testaceous or fulvous, violet or blue, and

black, affords, in conjunction with other characters, a sufficiently

satisfactory clue to the discrimination of the species. The gib-

bosity of the prothorax rises more or less gradually from the

apex, and is often slightly notched behind. Generally the punc-

tures on the head and prothorax are few and small; those on the’

elytra are in many individuals surrounded by a very evident

deeply-coloured border—areolated as they have been termed—

but other specimens, which do not appear to be otherwise diffe-

rent, have none or only very slight indications of this areolation.

Species of this genus occur in Northern India, Northern China

and in Japan, but Mr. Wallace does not appear to have found any

east of Borneo.

bicarinato-callosus, metasternum apice in sinu mesosterni re-

ceptum, corpus minus amplum, elongatum.

The real difference between this genus and the preceding ap-

pears to me to reside in the modification of the mesosternum,

which here rises to the level of the metasternum, and forms a kind

of small sinus or indentation which receives the apex of the latter.

Besides this character, the gibbosity on the disk of the prothorax

Longicornia Ma layana. 355

is bounded on each side by a longitudinal curved ridge, with its

concavity outwards. The sublinear antennz also are probably a

good although somewhat difficult character to seize. Mr. New-

man notices none of these points, the only strongly contrasted

peculiarity being the long parallel elytra of this and the broad

elytra of Astathes. The new species described below differs, ¢nter

alia, from the type (E. flava) in the posterior third of the elytra

being black, and the abdomen and legs fulvous.

Fulvous or reddish-fulvous, finely pubescent, the posterior third

or a little more of the elytra, black; head with a slight semicir-

eular or rather horse-shoe-shaped jie’ line between the eyes,

the convexity downwards, the front obscurely punctured ; pro-

thorax impunctate, the ridges glabrous, black and shining; scutel-

Jum semicircular; elytra finely and irregularly punctured, the

longitudinal lines only slightly elevated; body beneath and legs

fulvous, the outer edges of the intermediate tibize, in one speci-

men, bordered with black hairs; antenne black, a little shorter

than the body in the male.

The habit of this genus is very similar to that of Astathes, but

the body is in no respect depressed. In its technical characters,

however, it is more nearly allied to Chreonoma, differing principally

in its longer and more cylindrical scape, the bisinuate base of the

prothorax, and very convex outline. The two species described

below agree in coloration, but the prothorax of the second is dif-

Differs from the former in the narrower prothorax, the apex

much smaller ; the elytra also are less convex.

TROPIMETOPA.

Tropimetopa, J. Thomson, Syst. Ceramb. p. 118.

Characteres ut in Astathe, sed caput antice inter oculos bicarina-

tum; elytra depressa, breviuscula, ampla, haud carinata,

apicibus spinosis.

M. J. Thomson separated this genus from Hecphora (or as it

should be written Hephora) on account of the presence of two

frontal ridges—one at the base of each antenna—and the de-

pressed spined elytra. The former character, however, is found,

although in a less degree, in Ecphora testator (an African species).

Still, when we take into account the gibbous prothorax of Ecphora,

prolonged posteriorly so as nearly to cover the scutellum, and

contrast it with that of Z'ropimetopa, which is nearly of the same

form as in Astathes, we cannot hesitate to adopt the genus.

Characteres ut in Chreonoma (post, p. 358), sed elytra angus-

It must be admitted that this genus is rather weakly charac-

terized, and it might perhaps be viewed simply as an aberrant form

of Chreonoma, nevertheless the spined apices of the elytra are so

exceptional, occurring only again in this sub-family in Tropimetopa,

that I think its separation will lead to a better appreciation of the

genera, and serve to make Chreonoma amore nearly homogeneous

group. There are two specimens. In the smallest one, probably

the male, the antenne are a trifle longer than the body ; in. the

other, they scarcely reach to the end of the elytra.

Of the two species of Plaxomicrus (potius Placomicrus) origin-

ally described by M. J. Thomson (Arch. Ent. i. 57) one may

be referred to Chreonoma ; the other—P. ellipticus—standing as

the type, according to the author’s latest arrangement in his

“Systema.” M. Thomson, however, sinks Ais name as asynonym

of M. Chevrolat’s Aslathes Fortunei, of which I cannot find any pub-

lished description. I cannot help thinking that there is a mistake

here, and that the two are perfectly distinct, the latter belonging

to the present genus. The species described below are all of

small size compared with Astathes, and are sparsely clothed above

with short erect hairs, each issuing from a puncture in the derm ;

the elytra are generally punctured at the base only, the punctures

nearly disappearing or becoming smaller towards the apex; the

scutellum fits so closely to the elytra as to be made out with dif-

ficulty ; the second joint of the antennz, generally so very short,

is here, as in Cyanastus, two or three times longer than its dia-

meter,

PuytTaciin”®.

Since the commencement of this work I have examined a long

series of specimens of the two great genera Glenea and Oberea,

and their cognate forms, but however different the most typical

species of the two groups may appear to be, I have come to the

conclusion that there is no satisfactory division to be made be-

tween them, Scytasis, for example, combining the prominent

characters of both; while there are other genera with their cha-

racters so mixed that there is obviously nothing to be gained by

separating them from the true Phytcectine. It may be a question

even if the Amphionychine are sufficiently differentiated by their

double or deeply-cleft claws, in contradistinction to the dentate

or simply appendiculate claws of the Phyteeciine. The abruptly-

deflected sides of the elytra, which are supposed to characterize

the former, are found in many genera of the latter, so that the

structure of the claws appears to afford a safer diagnosis be-

tween the two groups.

Taking then the three genera Phytcecia, Glenea, and Oberea,

with their allies, as forming one sub-family, its most salient charac-

ters are found in the claws having a flattish tooth or appendage at

the base of each, a peculiarity which is structurally scarcely dif-

ferent from the bifid claw of the Amphionychina, the inner branch

being merely abbreviated, and rounded off or more or less obtuse

-at the edges: in their greatly exserted anterior coxe, which are

sometimes perfectly conical, as in Nitocris: and frequently in

Longicornia Malayana. 363

their abruptly-deflected elytra, which, in the few species of Glenea

with simple or nearly simple claws, will distinguish them from

Saperdine.

While the Amphionychine are confined to tropical America,*

the Phytaeciineé are spread over the rest of the world, except

Australia and probably many or most of the Pacific Islands.

When we consider that Mr. Wallace detected above 160 species

of this sub-family in New Guinea and other parts of the Malayan

Archipelago, we cannot but be struck with its entire absence

from Australia; but it is only one among many instances which go

to prove how thoroughly distinct are the beetle-faunas of the two

regions. In the present Collection the great bulk of the species

is confined to Glenea and Oberea. The latter genus is known in

Europe. The 163 species here described I have distributed into

ten genera, but a few Oberee@ remain for further examination.

This genus was first described by M. de Castelnau in 1849,

under the name of Sphenura, a name previously used for a genus

of birds, and was founded on S. novemguttata of Dejean’s Cata-

logue. Mr. Newman, in 1842, changed the name to Glenea, and

described several new species from the Phillippine Islands; and

M. J. Thomson,* in his various works, has since added a very

* Jn the “ Archives Entomologiques,” Glenea was treated as identical with

Stibara, Hope, but subsequently it was considered by M. Thomson to be

sufficiently differentiated by its tumid prothorax, to which may be added the

bicarinated disk of the elytra, and the stouter and more distinctly articulated

antenne; the two last characters would, however, exclude Lamia nigricornis,

Fab. (Ent. Syst. i. pt. 2, p. 270), hitherto included in it. This species has

also a habit so peculiar that, I think, it should form the type of a distinct

group, which may be named aud characterized as follows :—

NICOTELEA.

Caput antice quadratum; oculi mediocres. Antenne robust, breviuscule,

articulis cylindricis. Prothorax lateraliter tumidus, disco irregulari.

considerable number to the list. Although there is a sufficiently

natural resemblance running through the whole of the species, so

that they may be recognized at a glance, we feel our ideas of the

generic boundary somewhat disturbed when we observe the great

discrepancy which exists if some of the species be compared with

others, for example, G. picta with G. miles, or G. Vesta with G.

Delia. Nevertheless there appear to be no characters by which

a satisfactory separation may be made. The division of the species

by intervening lines, which I have made in the attempt to indicate

their affinities, is one chiefly dependent on colour, and colour in

this genus, so far as it depends on ornamentation, is to a certain

extent variable. In the species whose trophi I have examined

with the hope of finding some reliable characters, the labium was

more or less hexagonal, its palpi arising from a little within the

two lateral angles, the last joint being fusiform and pointed, but in

G. citrina I found the labium ovate, with its palpi very short, and

the last joint very stout and broadly truncate. In two nearly

allied species, however,—G. spilota and angerona,—the palpi are

of the normal form. The dorsal extremity of the anal segment

of the abdomen of the males is often furnished with two pro-

cesses, varying in size, close together, or divergent ; these and the

zedeagus might perhaps furnish reliable characters for the discri-

mination of closely allied species.

Many of the Glenee are very striking and handsome in-

sects, Mr, Wallace informs me that they are found in sunny

glades in the forests, settling on leaves, rarely more than one

individual being seen at a time, and they fly off rapidly when

disturbed. They are almost entirely confined to the Malayan

region and to West Africa, none, so far as I know, being found

in South Africa* or in Australia; but from the former region

they extend to Northern India, China} and Japan, although in

* A nearly allied genus, however, distinguished by its antenne gradually

thicker towards the apex, and its abdomen composed of segments nearly equal

in length and the small size of the interfemoral process of the basal one, seems

tolerably abundant in species—although very rare as to individuals—in

Natal and at the Cape. I propose to call it “‘ Blepisanis;” the type is Sa-

perda Bohemani. It will include several new species, which I hope to publish

very shortly; one of them has a remarkable spine on the second abdominal

segment.

+ A species from Northern China, published by Mr. W. Wilson Saunders

(Glenea Fortunei), has been recently separated from that genus by Mr. Bates

under thename of Paraglenea ; a second species from Formosa was described at

the same time (Proc. Zool. Soc. 1366).

very diminished numbers; in another direction a species has been

described by M. Thomson from New Caledonia. Glenea grisea

and Glenea fulvomaculata were once found together, so as to lead

Mr. Wallace to infer that they were male and female; we have,

however, positive proof that some insects at certain times do not

know what they are about, or at least that they are not very

fastidious, and I suspect G. grisea is one of them.

‘372 Longicornia Malayana.

Head and prothorax dark chalybeate, with a thin whitish to-

mentum, but thicker and forming spots on the cheeks, front and

base and sides of the prothorax, the latter with a broad but well

marked longitudinal elevation posteriorly; scutellum elongate,

rounded posteriorly, chalybeate, the apex white; elytra brassy,

very dark at the base, yellowish in the middle and passing into rich

purple, with blueish reflexions towards the apex, a few spots on

the basal half composed of a short whitish pubescence; body

beneath purplish or blue, glabrous, with indefinite white spots,

arranged in two lines along the middle of the abdomen, and with

irregular stripes on the sterna; legs chalybeate-black, the pos-

terior femora, except at their apices, luteous; posterior tarsi and

lower portion of their tibize dull luteous; antennz in the female

very little longer than half the length of the body.

Length 11 lines.

This very distinct species is remarkable, in the female at least

—the only sex known to me—for the shortness of its antenne. G.

leucospilota, Westw. (Colobothea), has the same robust form, but is

considerably shorter, and bright green with white spots on the

elytra. It is from Manilla.

Stouter than any of the preceding, with the elytra much shorter

in proportion to the length, and considerably broader at the base ;

the prothorax gradually widening posteriorly, with its sides nearly

straight, the disk rather sparingly punctured ; scutellum elongate-

triangulay ; elytra with the suture white in the middle and con-

nected with a large transversely oblong spot on each side, together

forming the figure of a cross; outer spine at the apex well

marked.

Length 11—13 lines.

At once distinguished by the large cross-shaped figure in the

middle of the elytra, and by its more robust outline. One of my

specimens is almost black, with the same white spots, however,

as in the normal examples.

Rather short and stout, dark purple with white spots ; head

sparsely punctured in front; prothorax gradually contracting

posteriorly, the base decidedly narrower than the apex, the disc

and sides striped as in G. picta ; scutellum subscutiform, broadly

rounded at the apex; elytra broad at the base, each with four

white spots, the second from the base nearly central; body

beneath with white spots.

Length 9—10 lines.

In coloration this differs from G. picta in having only four

instead of five spots on each elytron, and from all the preceding

in the form of the prothorax. It seems to be a good species,

judging from the two specimens before me.

Not quite so narrowly elongate as G. picta, the prothorax more

parallel at the sides, or even narrower at the base, the sides a

little irregular in outline, the disk more distinctly punctured, al-

though the punctures are partially hidden by the pubescence in

some examples, and are found also extending to the sides; the

trochanters reddish-yellow.

Length 10—12 lines.

M. Thomson gives also, as diagnostic characters, the head

black, the elytra with two stripes on each at the base, and the

apical spot resembling the number 7 reversed; the latter is con-

stant in my specimens, but the two former vary; the reddish

trochanters also appear to be constant.

sparsely punctured in front, the rest nearly impunctate, two white

stripes extending from the lip to the vertex, another behind each

eye, and a spot on the cheek; prothorax nearly impunctate,* the

sides subparallel, three white stripes on the disk, a brown stripe

also above the coxz on each side; scutellum narrowly triangular,

pointed below, black, with a large, somewhat heart-shaped, white

patch in the middle; elytra not much expanded at the shoulders,

sparingly punctured, the punctures disappearing posteriorly, each

with 5—7 white spots, arranged longitudinally, the 2nd and 4th

often divided; body beneath more or less spotted with white, the

epimera and sterna sometimes almost entirely white; trochanters

blueish ; legs with a delicate whitish pubescence, denser on the

tarsi.

Length 12—15 lines.

The remark of Fabricius, ‘‘ Magnus in hoc genere,” inclines me

to consider this the species he had before him. It is also the

most widely distributed, and not likely, therefore, to have been

unknown to him.

Coloration similar to G. picta, but the elytra, equally narrow

and slightly incurved along the sides, taper more towards the

apex, characters which give this species an outline somewhat

different ; in the Singapore specimens this is accompanied with

a narrowly triangular scutellum, and a prothorax rather strongly

punctured, but the punctures in patches divided by smooth spaces ;

the Dorey and Amboyna specimens have, however, scarcely any

trace of punctuation, and the scutellum is decidedly broader,

although they are all similar in outline.

paler spot near the apex, which is also bordered with white; body

beneath violet, with white patches; legs violet, posterior tibiz

at the apex and their tarsi fulvous; antennz black.

This is a very narrow species, with the shoulders obsolete or

without the angle which distinguishes every other member of this

extensive genus; the antennary tubers are also approximate ; ne-

vertheless, so intimate is its affinity with the preceding that these

strong peculiarities can only be regarded as of secondary im-

portance.

of the eye pale blue; prothorax nearly impunctate, the sides

slightly rounded, a large semicircular band extending from the

base to the sides, where it is continuous with the band beneath

the eye, whitish or pale blue; scutellum subscutiform, whitish or

pale blue, except at the two anterior angles; elytra broad at the

base, gradually narrowing posteriorly, the apex of each termina-

ting in a single median spine, a large, somewhat lozenge-shaped

ring in the centre, but extending to the external margins, either

ochraceous or pale blue, behind the ring a pale blue oblique stripe

extending from the suture outwards and downwards; body be-

neath with pale blueish patches, especially at the sides of the ab-

dominal segments, the lateral patches in one specimen ochraceous ;

antenne and legs dark blue, with a slight pale blueish pubes-

cence.

Length 9 (¢)—12 (2) lines.

Very distinct from all other species of this genus on account of

the single median spine terminating each of the elytra. I have

only a,male and female, the latter on account of its size and the

clear ochraceous ring on the elytra surpassing the former in

beauty, and ranking perhaps as one of the most elegant of the

Longicorns. I have much pleasure in dedicating it to M. James

Upper parts dull brownish-black, the apex of each elytron

with a squarish fulvous patch; cheeks, sides of the prothorax,

the declivous portion of the elytra, and body beneath ashy ; fe-

mora and tibize luteous; tarsi covered with an ashy pile; an-

Very distinct in its coloration, but in general habit resembles

more nearly the foregoing species than any other.

Glenea Calypso. (Pl. XVII. fig. 3.)

G. nigro-tomentosa, sulphureo-figurata et lineata. (¢@ ).

fTab.—Sarawak.

Covered above with a dense black tomentum and varied with

sulphur-yellow lines ; head nearly glabrous, the eyes entirely sur-

rounded with a yellow pubescent border, except at the base, a

yellow line also bordering the epistome ; prothorax edged on all

sides with yellow; scutellum yellow ; base of the elytra, and a

stripe along the deflected side, an annular somewhat hexagonal

figure, connected along the suture, on the anterior part of the

disk, and posteriorly another series of lines uniting at the suture

and forming an X-like figure, pale yellow ; body beneath with a

sulphur-yellow pubescence, with luteous-glabrous spots on the

sides and middle of each abdominal segment ; legs black, trochan-

ters and bases of the femora luteous ; antenne black.

Length 8 lines.

The prothorax of this fine and very distinct species, of which

I possess but one specimen, is rather more convex and rounded

at the sides than in the generality of the Glenee.

Head and prothorax jet-black, stripe on the vertex, continuous

with another on the prothorax, ochraceous; scutellum semicircular,

ochraceous ; elytra with a large fawn-coloured patch anteriorly,

bordered at the shoulders with black, and having a triangular och-

raceous spot at the side, posteriorly, but before the middle, jet-

black, except a quadrangular prae-apical ochraceous spot not quite

extending to the suture; body beneath, sides of the prothorax,

coxze, and anterior and intermediate tarsi, covered with a dark

smoky-grey pubescence, rest of the legs yellowish-testaceous ;

antennez black.

Length 6—7 lines.

The punctures on the elytra are confined to the comparatively

small space occupied by the fawn-coloured patch, and this has

apparently suggested the specific name.

Possibly the male of the last, but the head and prothorax are

without the bright ochraceous stripe, and the scutellum is black,

except a slight border of fawn-colour at the apex; the narrower

outline in this case is precisely what might be looked for in the

male ; the prothoracic stripe in G. anticepunctata, however, is

composed of hairs longer than the rest, set transversely, the ex-

tremities of which form a narrow elevated line along the middle,

a character which is quite opposed to the uniform, somewhat

tomentose, pubescence of the example before me.

Perhaps only a variety of the last, which it nearly resembles in

Resembles G. udetera, but much more robust; no spot on the

vertex, the cheeks whitish, the elytral ochraceous band before

the middle, the pree-apical spot triangular and forming with its

fellow a transverse somewhat lozenge-shaped patch, not ex-

tending to the carina as in the two preceding species, the punc-

turation on the shoulders much coarser, the outer apical spine

very short, and the whitish pubescence beneath more interrupted

and covering part of the last abdominal segment; the antennz

dark brown.

with from eight to ten small spots on each, in one specimen a

short line between the shoulder and scutellum; body beneath

nearly uniformly dark chesnut-brown, the metasternum and its

episterna covered with a dense snowy-white pubescence, except

in the middle; legs brownish, tarsi with a thin whitish pile; an-

tennz brown.

The strictly limited white patch on each side differentiates this

species from every other in the collection, except G. ochraceovit-

In its indefinite coloration, giving a dull leaden hue to the upper

surface, this species resembles the last, but, infer alia, the scu-

Remarkable for its comparatively long prothorax and short ely-

tra; in the central stripe and general appearance it resembles the

next.

The preceding members of this section are rather short and

robust; but this and the rest of the section as far as G. Latania

are more slender; from that point they are again stouter; there

is, however, an obvious connexion between them which forbids

any division. G. regularis, Newm., (G. Kraatzii, Thoms.), be-

and no mention is made of the white terminal joints of the

antenne.

In this species the anal processes are rather long, and slightly

divergent. G'. versuta, Newm., differs principally in the antenne

having the third joint white at the apex.

Hab.—Ceram.

Perhaps only the female of the preceding; it is remarkable,

however, for the opake dense squamiform pubescence of the black

portion, and for the whiter and longer pubescence of the stripes ;

the outer apical spine is also smaller, and the general outline is

much more robust, but scarcely exceeding what might be expected

in the female.

‘The variation in the extent and distinctness of the white stripes

in the two individuals before me shows the uncertainty of this

class of their characters; all that remains, therefore, to differen-

tiate this species is the blue colour of the elytra, changing like

shot silk in certain lights, and the pale ashy stripes; these give

the insect a primd facie distinctness totally different from any

other in this section.

raceous lines, including the sutural lines which extend to and

cross the apex to the exterior mucro, the second stripe extends

from the base to a little beyond the middle, the third lies midway

between the second and the carina, and extends nearly to the apex ;

body beneath and legs reddish-yellow, sides of the sterna and

abdomen ochraceous ; antenne blackish.

Closely allied to the last, but the vertical stripe dividing be-

tween the eyes and embracing a large black patch; the prothorax

larger and more constricted posteriorly; the scutellum less

rounded and longer ; there is also a narrow humeral stripe as in

G. mathematica, which does not, however, extend to the apex, and

the sutural stripe is narrower and of uniform breadth, spreading

out however at the base.

This bears a close resemblance to G. algebraica, but it is

very considerably shorter, the elytra flatter posteriorly and their

apices oblique and less deeply emarginate, the outer spine is nearly

obsolete, and there is no trace of the angles formed by the deflected

sides ; the stripe on the elytra spreads out at the base so as to

touch the shoulders, and the legs are darker: there’is only one

example; how far, therefore, some of these characters may be

permanent must be left for future observation.

G. capite, prothorace, elytrisque postice aterrimis, niveo-maculatis, cxteris

elytrorum rufo-cervinis; corpore infra niveo-variegato; antennis pedi-

busque luteis.

Head, prothorax and apical third of the elytra jet-black, spotted with

snowy-white, rest of the elytra of a pure reddish-fawn; face, two lines on the

vertex, and cheeks white, the former with a black vertical line; prothorax

rounded at the sides, contracted posteriorly, the disk with eight oblong

spots—two in the centre and three on each side; elytra irregularly punctured,

the black apical portion with four white spots; body beneath with a pure

white pubescence at the sides ; legs and antenne luteous.

Length 5 lines.

One of the most strongly-marked species in regard to coloration in the

genus; the eye is unusually large, its lower border approaching the mouth,

the face being a little transverse.

Glenea maura.

G. aterrima; pectore albescente; abdomine cinereo.

Size and form of the last, but the entire upper surface, as well as the an-

tenne and legs, are jet-black; pectus with a whitish, the abdomen with an

ashy pubescence; face rather long, with a whitish line on each side, eye of

the ordinary size and remote from the mouth.

This species also slightly departs from the normal form; the

stripes are partly due to the colour and greater density of the

pubescence.*

The absence of a carina on the elytra is, as we have previously

noticed, opposed to the technical character of this genus; never-

theless the affinity to the following species, and, in a lesser degree,

to the last preceding, is too obvious to allow of any other loca-

tion.

In my specimen of the female of this species the apex of the

third antennal joint and the tarsi have a blueish tinge. It is a

somewhat aberrant form, and, according to Mr. Wallace’s tickets,

is a mountain species, taken at a height of 2,000 feet.

The habit and colour of the type of this genus give it the ap-

pearance of a Callichroma, among the species of which group Mr.

Wallace had hastily placed it. Notwithstanding it is scarcely to

be differentiated from Gilenea, except by its long posterior legs

with their compressed tibiae, and, what in this group is very un-

usual, the tuberculate disk of the prothorax.

This genus was long confounded with G‘lenea under the name

of Sphenura, but this name being preoccupied was changed by

Mr. Newman in 1842 to the former. Sixteen years later M. Chev-

rolat, having learnt this fact “ d’apres M. Newman,’’ changed it

again to the queer-looking word ‘ Nupserha” (an anagram of

Sphenura), although he had previously adopted Gilenea, as it is

now limited. In the work quoted above M. Thomson has satis-

factorily differentiated this genus, which, by its flattened elytra,

short legs, subequal abdominal segments, and general appear-

ance, is a natural one and very distinct from Glenea. It con-

tains several African species, some of them closely allied to the

Asiatic; they are all yellowish or brownish-yellow or yellowish-

red, with the apices of the elytra and the last abdominal segment

generally black. The carina on the deflexed portion of the

elytron is not always very evident, and often there is also a

shorter carina on the disk.

The characters of this genus are in some respects intermediate

between Glenea and Oberea, although more nearly allied to the

Jatter ; the well-marked antennary tubers, however, approximate

at the base and semi-erect, give the head a concavity and narrow-

ness in front quite different from the same part in those genera.

In Tanylecta and Ectinogramma—Malayan genera not in the Wal-

lacean Collection—the antennz are also approximate, or even

almost contiguous, but the former, inter alia, has the normal

form of abdomen, and the latter has the basal joint of the an-

tennz very long, and all the legs very short.

The form and coloration of the only species at present consti-

tuting this genus is very different from that of any Glenea, and

bears a striking resemblance to some of the Clylin@ sub-family.

Nevertheless the technical characters separating it are not very

satisfactory, seeing that simple claws in the males of certain

Glene@ are vot unknown; the scape is, however, longer and

more slender than obtains among any species of that genus, and

the prothorax is more cylindrical, gradually narrowing towards

the base.

This genus is uncertainly referred to this group from a general

resemblance in habit and colour to some South American forms;

in the latter respect it bears a marked resemblance to a Clerid

from the same district with itself. Like Zephrocoma it might per-

haps be better placed with the Saperdine. It is not unlikely that

the white may have been originally yellow.

The only individual I have seen of this genus has very much

the appearance of a female Glenea, which we might expect would

be allied to G. grisea; it has not, however, the sides of its elytra

deflexed as in that genus, and hence, perhaps, it might have been

better placed with the Saperdine, but until we know the male,

this point cannot well be decided.

The type of this genus, O. oculata, Linn., is one of the least

characteristic of the whole of the large number of species belong-

ing to it. Generally they have a very long and narrow body, with

the elytra scarcely broader than the prothorax, the latter almost

cylindrical, and the posterior legs not passing beyond the middle

of the abdomen, but in O. oculata none of these characters hold

good ; it is the stoutest of the genus, and offers a marked contrast

in those respects with most of the species. Nevertheless there is

a gradual passage between this and the slenderest of the forms,

like O. acicularis or O. ophidiana. « Mr. Newman’s genus Isosceles,

is in nowise distinguishable; it was probably formed at the same

time as M. Mulsant’s, but the latter author has priority of date, at

least on his title page. M. James Thomson, in adopting it, dif-

ferentiates it on the ground of the antenne ‘‘longer than the

body,” but this is a purely arbitrary distinction in such a group

as the present. The genus has its head-quarters in Borneo,

whence it radiates to Java, New Guinea, the Philippines, and

Mantchuria; it is represented by nearly a dozen species in

Europe, a few in North America, but none in Africa beyond the

desert, or in Australia. The species frequent plants, nestling

among the leaves, and fly slowly and in an undulating manner.

orange-red; eyes small; prothorax slightly narrower than the

head; scutellum subtriangular ; elytra moderately elongate, the

disk with a thin greyish tomentum ; body beneath and legs black,

with a sparse greyish pubescence ; antennz shorter than the body,

Length 7 lines.

Both my specimens appear to be females, but there is a slight

variation in the form of the prothorax, the sides of one being

nearly parallel, while in the other they decidedly widen to within

about a third of the base; the species is, however, very distinct

from its allies on account of its small eyes.

Allied to the last, but the elytra are proportionally shorter and

covered with a pale silky-grey pubescence, varying according to

the light, and the antenne are black at the base, except the fulvous

condyle of the scape, but become paler from the fourth or fifth

joint, owing to the greyish pubescence with which they are clothed ;

and the abdomen is unicolorous.

the former with a well-marked mesial groove, the latter oblong,

slightly rounded at the sides ; scutellum squarish ; elytra scarcely

elongate, a little narrower behind the shoulders, minutely pubes-

cent, a little glossy, with a brownish tint at the sides posteriorly ;

body beneath, legs and antenne fulvous, the latter about as long

In form and colour much resembling the last, but essentially

differentiated by the very much shorter feet; the elytra are also

Fulvous-testaceous, inclining to a pale orange on the head and

prothorax, which are very finely and sparsely punctured, the for-

mer broad and rounded in front, with a mesial groove; scutellum

transversely scutiform; elytra scarcely elongate, compared to the

head and prothorax as 53 to 2, finely seriate- punctate, the punc-

tures nearly obsolete on the apical third, the outer sides and

apices margined with blackish; body beneath and legs a pure

pale luteous, posterior legs extending to the end of the abdomen ;

antennez black, shorter than the body.

Length 7 lines.

On comparing the Penang specimen, alluded to in the work

quoted above, with my type from Singapore, I think it would

have been better to have kept them apart; the former is much

longer, the elytra being to the head and prothorax nearly as 74 to

2, and the head is much more decidedly punctured; the colours

are, however, nearly alike, and the general appearance, except

the length, almost identical.

base, gradually becoming finely punctured at the apex, the sides

behind the shoulders and the posterior third blackish; body beneath

and legs pale fulvous ; antenne as long as the body, black.

This and the last are rather robust species for the genus, and

are much alike in appearance; the form of the scutellum, how-

ever, is alone decisive as to their distinctness.

Very narrow, broader at the shoulders, otherwise nearly linear,

black ; head, prothorax, shoulders and anterior femora brownish-

red; abdomen and legs black, the two basal segments, except the

hind part of the sides of the second, covered with a pure silvery-

white pubescence; prothorax slightly gibbous in the middle, and

somewhat glossy ; elytra contracted in the middle, the space near

the scutellum smooth and impunctate ; postpectus dark brownish-

red; posterior legs twice as long as the intermediate; antennz

black, about as long as the body, the third joint shorter than the

scape.

This species differs from the normal Oderee in the shortness

of the third antennal joint, and in the extreme narrowness of the

middle of the elytra.*

TMESISTERNINE.

Until the publication of M. James Thomson’s ‘“ Essai” it was

usual to regard the T'mesisternine as Cerambycide, chiefly on ac-

count of their porrect head. The presence, however, of grooves

in the anterior tibia, and the corneous lower lip, have determined

me also to treat them as Lamiide. With regard to the first-men-

tioned character, many species, and even genera, are now known

with vertical heads ; it is therefore evident that we have come to

a point when the character has lost its primary importance. The

sub-family is, in fact, a transitional one, and shows an affinity

not only to the Cerambycide, but also, on account of the margined

sides of the prothorax of many of the genera, to the Prionide.

It might have been better, perhaps, to have separated the least

typical part of this sub-family from the true 7mesisternine, or

those with a porrect head; but there are some genera, Crinotarsus,

Leptonota, &c., in which the head is almost or quite vertical in

repose; and then again Hestima and Arsysia, from the characters

of their sterna, could not well be placed in a different group.

There is certainly a great amount of diversity among the species,

but the genera are tolerably homogeneous, with the exception of

Polyxo and Tmesisternus itself.

One of the most curious points connected with this sub-family

is its geographical distribution, According to the present state

of our knowledge, it is almost entirely confined to the islands

lying east of Borneo and Java. The only species to the west are

Trachelophora curvicollis in Sumatra and Java, and Mulciber bi-

guttatus in Singapore. To the south we know only of three spe-

cies in the vast Australian region—Temnosternus planiusculus, T.

dissimilis and Anastetha raripila; in New Caledonia and the

Feejee Islands we find the genera Spintheria, Blapsilon, Enicodes,

Buprestomorpha, Leptonota and Crinosoma; in New Zealand,

Tetrorea, Navomorpha and Coptomma; and in the Philippines,

Ichthyodes, Urocalymma and Demodes. They probably exist also

in New Britain, New Ireland, the Salomon group, the New He-

mata. Pedes parum robusti; femora fusiformia; tarsi equales; ungues

basi obsolete dentati. 4bdomen conicum, segmentis subzequalibus.

A robust form allied to Glenea, but at once differentiated by the angular or

toothed sides of the prothorax, and the distinetly jointed antenne. The

type was described by Mr. W. Wilson Saunders under the name of Lamia

croceocincta (Tr. Ent. Soc. ii 178, pl. xvi. fig. 6). It is about 8 lines long,

black, the sides of the prothorax and two bands on the elytra pure yellow.

brides, and the Louisade Archipelago; but except a few species

vaguely indicated by the late Pere Montrouzier from Woodlark

Island and San Cristoval, we know nothing.*

It is scarcely necessary to observe that between this sub-family

and the preceding there is not the slightest affinity, but in a

linear arrangement it is hardly possible to avoid the juxtaposition

of incongruous groups.

There is a genus of Fishes, T'rygonoptera of Miller and Henle,

anterior by some years to M. Perroud’s name Trigonoplera.*

Although the two are not identical, they are so in sound. I

do not myself, however, consider this ought to be an abso-

lutely valid objection, but there is so determined a stand in some

quarters against all names that are only nearly alike, that I have

thought it the least of two evils to make the change now, before

any more new species are added to the genus, rather than leave

it to no distant future when the name T'rigonoptera would be

certainly sunk. ‘This genus was considered by M. Perroud to

be near Megabasis, with which it has nothing more in common

it has reappeared under the form of Trigonopterus, for one of the Staphy-

linida.

than the triangular outline of the elytra. The bicarinate front

appears to be a good generic character and to distinguish the

genus from its allies; the carine are two raised vertical lines, and

occur between the eyes, one very strongly marked, incurved, in-

closing between them a concave oblong space, through which

passes the mesial groove; in A. tessellata, the carinz are nearly

united below. The elytra are also abruptly bent down at the

sides, in some species causing a sharp angle on the line of de-

flection. ‘I'he coloration depends on densely pubescent lines or

spots, varying greatly in amount in the same species, lying on a

dark derm clothed with an extremely minute pubescence, only

visible under a good lens.

Black, subnitid, minutely pubescent, with stripes or lines of a

coarser and nearly pure white pubescence; head with a line round

the eye, the mesial line, and clypeus white ; prothorax with two

stripes on each side, a line along the base, and sometimes a zig-zag

mark behind the middle of the disk; scutellum nearly semicir-

cular; elytra with a band before the middle, sometimes inter-

rupted at the suture, three or four broken lines, or spots, at the

base on each side; in the freshest specimens, a line commencing

behind the band, then branching off into three or four, two of

which unite lower down, in other specimens these lines are broken

up without any connexion between them; the suture posteriorly

appears to be always finely bordered with white as far as the

band, apices rather broadly truncate, the outer angle broadly

mucronate; body beneath black, the sides of the abdominal seg-

ments and the episterna bordered with white; legs and three or

four basal joints of the antennz covered with a fine greyish pile,

body beneath nearly uniformly white at the sides, the central line

only glabrous glossy-brown; intermediate and posterior tibize

Not very distinct from the last, the two spots on the elytra, and

the uniform pubescence on the sides of the sterna and abdomen,

being almost the only differences. ‘The Mysol specimen is brown,

with the markings nearly obsolete, except the two elytral spots,

which are pale greyish ; the New Guinea variety is much smaller

(43 lines), without any stripes on the prothorax, and the fore and

intermediate femora are rusty-brown. It is quite possible that

these are all forms of 4. maculata.

coarser ochraceous pubescence; head nearly impunctate, line

round the eye, mesial line and clypeus ochraceous ; prothorax re-

motely punctured, indistinctly striped, the middle clouded with

ochraceous; scutellum nearly semicircular ; elytra with about five

stripes on each, the outermost near the margin, the four on the disk

interrupted a little behind the base, and again more irregularly

towards the apex, the latter obliquely emarginate, the outer angle

narrowly mucronate; body beneath with an ochraceous pubes-

cence at the side, the middle line glossy-brown ; legs with a greyish

pile; antenne slightly pubescent.

Besides the coloration, which may perhaps be variable, the

apices of the elytra will at once differentiate this species from the

preceding.

proximate, the interval apparently glabrous; scutellum nearly

semicircular, yellow ; elytra with about four lines of broad oblong

spots on each, the spots nearly entirely interrupted obliquely at

the middle, partially also near the suture between this and the

base and again between the middle and apex, the latter trans-

versely emarginate, the sutural angle terminating in a short slender

mucro, the outer in a broader one ; body beneath reddish-luteous,

glossy along the middle line, the sides delicately pubescent ;

antenne, femora, and tibiz luteous, with a delicate greyish pile ;

tarsi ashy.

thorax robust, a broad grey stripe on each side, the disk uniformly

pubescent; scutellum narrow, greyish ; elytra rather broad at the

base, several oblong spots arranged much in the same way as in

the preceding, but very dull and indistinct, the apex of each ely-

tron obliquely emarginate, each angle terminating in a broad

mucro; body beneath brownish-testaceous, glossy, covered, ex-

cept on the middle line, with a very delicate greyish pile; legs

slightly transverse, with a glabrous central line; elytra with rather

small scattered punctures extending nearly to the apex, the ashy

colour divided into several large patches by irregular black lines,

the apices with the external angle strongly mucronate; body

beneath and legs light ashy.

My unique specimen of this very distinct species wants the

greater part of the antennz, but what there is shows that they

This last character, although general among the more typical

culiar to this genus in that part of the sub-family which possesses

the usual vertical head of the Lamide. A slight emargination of .

the mesosternum is found in Arsysia, very different, however, from

the triangular notch of Hestima.

This genus was placed by M. Perroud between Pelargoderus

and Gnoma ; but there is no doubt that it is most nearly allied

to Anapausa, Mulciber, and particularly the Philippine genus

Urocalymma. The name was probably suggested by its supposed

affinity to Gnoma, but it is likely to prove deceptive, as there is

very little to warrant its application. Only one species is known,

Latreille gave a very short description of this genus, but con-

sidering the few genera then recognized, one sufficiently dis-

tinctive. None of the species were at that time published, but,

in a note, they were said to have “ great affinity to Callidium

variegalum, lineatum, and sulcatum of Fabricius.” By some over-

sight Serville (Ann, Soc. Ent. Fr. iii. 72), quoting Latreille for

the genus, refers to it the three species which its author con-

sidered to be only its allies. Moreover, Serville’s first character,

and the essentially diagnostic one, the prothorax lobed poste-

riorly, does not apply to the first species he quotes, C. variegaium,

now the type of Coptomma, Newm. How little Serville un-

derstood the genus is shown by his having placed it between

Listroptera and Deilus.

Longicornia Malayana. 461

Between the extremes of this large genus the variations from

the type, except in colour, are not very remarkable. In

many species a large centro-basal spot is found, and as this

is generally glabrous and occurs in the most convex or exposed

part of the elytra, it might be thought to be due to abrasion; I

believe, however, that this is not the case, as it is far too general

and occurs in the freshest examples. The greater part of the

species are spotted or banded with white or grey, one species

only is striped—7'. phaleratus ; these colours are principally due

to a very dense pubescence hiding the derm beneath, the intervals

having a finer and sparser pubescence, through which the derm

appears. ‘There is very little difference between the males and

females. They are generally found in the gloomy dark forests,

gnawing bark or twigs of trees, and have a peculiar drone when

flying ; they are, however, sluggish animals, dropping down when

touched, with their Jegs and antenne drawn close in to their

bodies. The descriptions here given will not always be found in

exact accordance with other authors, especially those of MM.

Blanchard and Boisduval, but in most cases my specimens have

been compared with such of their types as are in the Collection

of the Jardin des Plantes.

This species differs from the preceding in its narrow, nearly un-

broken bands, the larger size of the elytra in proportion to the

prothorax, and other characters; it is easy to conceive interme-

diate forms which might bridge over these differences, but the

two look very distinct for nearly allied species.

narrow and rather conyex, punctures small and scat-

tered, median line narrow, brownish, scarcely glabrous ;

scutellum rounded; elytra wedge-shaped, rather broad

at the base, a large centro-basal spot glabrous, glossy

other behind, the middle, apices very slightly emargi-

nate; body beneath reddish-gray at the sides, spotted

with blackish ; femora densely pubescent, grayish ; tibiee

Resembles 7. analis in its narrow and convex pro-

thorax, but inter alia the elytra are broader at the base,

and their apices scarcely emarginate.

Hab.—Dorey.

Differs from 7. agnatus in its oblong-ovate elytra,

and thin obliquely-emarginate apices; the ,femora are

also less thickened, and the prothorax is very much

broader, more depressed, and the sides from above look

as if margined from their rather sudden deflexion. There

is only a specimen of each species, the former apparently

a male, the present, notwithstanding its broad prothorax,

a female ; it is not likely, therefore, that they belong to

the same species.

Black, minutely pubescent generally ; head and pro-

thorax ashy, with a tinge of bluish, mesial groove on

the former, and central line on the latter, with the edges

of the punctures on both, glabrous, black ; scutellum

nearly round, ashy, black in the middle; elytra appa-

rently speckled with ashy, the punctures being more or

less ringed with black, an interrupted ashy band before

the middle, another behind the middle, a third toward

the apices, these bands with a little more black at their

neath glossy black, the sides ashy, spotted with black ;

legs and antenne dark brownish luteous.

The legs in this species are unicolorous, which inter

alia will distinguish it from the others of the ashy

series.

Tmesisternus torridus.

T. rufo-brunneus, griseo-varius vel fasciatus; elytris

Hab.—Gilolo, Batchian.

Light reddish, varied or banded with gray; head

with the mesial line and two lines behind each eye

brown, the clypeus produced in the middle ; prothorax

grayish, with three brown thinly pubescent stripes ;

scutellum somewhat semicircular, brown with two gray

stripes; elytra with irregular large grayish patches,

mostly confluent at the base, at the middle a broad

V-shaped band, two arched bands below, the second

much narrower and flexuous, the apices also grayish,

each with the external angle produced, near the suture

on each elytron three raised lines, the intermediate one

the most prominent, especially posteriorly ; body beneath

grayish spotted with brown, the central line glossy

brown ; legs pale luteous, with the femora greenish, or

the legs entirely bright luteous, thinly pubescent ; an-

tenne reddish-luteous.

Length 9-10 lines.

In this very distinct species the apex of the clypeus is

so produced as to create a tolerably distinct emargination

on each side, above which is an arched raised line which

seems to be the edge of the clypeus itself; the raised

lines on the elytra occur also in a few other species, such

as 7’. marmoratus, T’. vagus, T'. herbaceus, &c.

cent, the edges of the punctures and a broad longitudinal

glabrous stripe on the disk excepted ; scutellum semi-

circular, the middle glabrous; elytra mostly covered

with an extremely delicate pubescence, an oblong

glabrous patch on each side below the scutellum, mid-

way between the base and middle a broad semicircular

spot, and on each side directly below it another spot,

behind the middle a semicircular band a little inter-

rupted at the sides, between this and the apex another

semicircular band, these spots and bands, as well as

some indefinite patches at the base, composed of a dense

opalescent pubescence; body beneath with a duller

opalescent pubescence on the sides, spotted with luteous

brown; legs and antennz more luteous, with a delicate

grayish pubescence.

Length 11 lines.

This handsome species is unfortunately unticketed,

but from a certain resemblance in the disposition of its

markings to 1’. lotor, it is probably from the Moluccas,

Mr. Wallace thinks from Ceram. It is not only very

distinct on account of its peculiar opalescence, but it 1s

also remarkable on account of its scutellum, which is

perfectly straight at the base, and not received into an

emargination of the opposite part of the prothorax.

also ashy ; body beneath ashy, the middle line glabrous,

brown ; antennee and legs pure luteous.

Length 8 lnes.

I was at first inclined to regard this species as a variety

of the last, but in addition to the apparently decided dif-

ferences of colour, there are also other slight variations

in regard to puncturation, convexity, &c.

above, mostly glabrous, with several oblong spots, com-

posed of a gray pubescence, irregularly dispersed ; body

beneath and legs dark brown, with a close grayish pile;

antenne greenish or brownish.

Mr. J. Thomson has founded his genus Apolia on this

species, apparently because of its unarmed prothorax ;

the two lateral teeth are, however, present, and although

very small, are perfectly distinct.

with the anterior lateral tooth very small, the posterior

obsolete ; scutellum nearly semicircular; elytra convex,

rounded at the side, the apices obliquely truncate, not

emarginate, each elytron with five slightly elevated lines,

which are more or less rugose or interrupted by punc-

tures, the first and third lines connected behind and

nearer the apex, the united line joiming the fifth; body

beneath glossy brown, the sides grayish pubescent ; legs

and antennee brown, with a grayish pubescence.

An obscurely coloured species, but very distinct; the

pubescence in the intervals of the raised lines gives the

elytra a striped appearance, which, however, may not be

obvious in fresh examples.

Slender, dark brown, covered with a very dull grayish

pubescence ; head sparsely punctured, the vertex nearly

glabrous ; prothorax rather closely punctured, impunctate

on the central line, glabrous except at the sides, glossy

brown, the base very considerably broader than the

apex; scutellum transverse; elytra somewhat elongate,

rather broad at the base, but gradually and rapidly nar-

rowing towards the apex, a short raised line in the middle

of each, a round glossy glabrous centro-basal spot, the

rest dull grayish-brown, with faint traces at the sides of

three or four oblique spots of a lighter colour; body

beneath grayish pubescent, the central line glabrous

glossy brown; femora greenish, their bases luteous;

tibize, tarsi, and antennz, which are very slender and

longer than the body, dull luteous.

Length 7 lines.

I have only one specimen of this species, and this does

not appear to be in its freshest state as regards pubes-

cence, &c.; it can not be confounded with any but the

following species.

In M. Perroud’s lengthened description and remarks

on this genus, he has not said a word as to the reasons

which induced him to separate it from T’mesisternus ; but

we infer from his italics that he was guided by the

“entirely divided” eyes, the form of the prothorax, the

lobed bases of the elytra, &c., and the non-clavate femora.

The first character is not exactly correct, a connection

between the two lobes really exists, and although the line

of union is very narrow, it is very distinct; the other

characters are good. The type, S. mirabilis, is sometimes

divided in collections into two or more species ; it would

not be difficult to find characters for half-a-dozen, but cha-

racters do not make species, and I cannot satisfy myself

that there is more than one. M. Perroud has, however,

described two, which seem to be, and no doubt are, very

distinct ; and as the work in which they appear is not

always at hand, I have given here the most essential of

Longicornia Malayana. 483

their diagnostic characters, so far as I have been able to

fix them from M. Perroud’s long descriptions. The first

—BSS. insignis—is supposed to be identical with Ichthyo-

soma nirabile, Montrouz. (non Boisd.), and is from San

Christoval (the easternmost of the Salomon Islands). It

is somewhat brassy green, the elytra have five bands, the

humeral angles are produced into a sort of pad (bowrrelet),

the angles of their truncated apices are slightly spined,

and each elytron has ten slightly “ sulciform strie”

marked with one or two rows of punctures more or less

coarse. The second—S. Mniszechti—is supposed to be

from Amboyna, and ought to be in the collection of

Count Mniszech, but is not. The head is glossy black,

a little bronzed; the prothorax is a glossy greenish-

black (noir verditre), between the two lateral lobes is a

sharp tooth, which is not so large as the one below the

margin; the elytra are also greenish-black, but with

violet reflections, and three bands, the shoulders are pro-

longed into a sort of plate, and the external angle of their

truncated apices is produced into a short sharp tooth,

each elytron has ten strize with the commencement of an

eleventh near the scutellum. The labrum is said to hide

the mandibles; this, if strictly correct, would be very

remarkable.

Mr. Wallace tells me of another species from Dorey

in the possession of Dr. Mohucke, ‘‘ green with bands

of dead gold.””? With regard to the new species described

below, it is not only obviously very distinct from any

of the above, but, in its coloration, it is quite different

from any other in the whole sub-family, and is as large

as the largest specimen of 8. mirabilis.

The peculiarly formed head of the male in this genus

is unexampled among the Longicornia. Owing to the

dilatation of the cheeks behind the eyes, the latter organs

are placed in front, or rather, in relation to its position,

on the upper surface of the head.

In Henicodes,* a genus of this sub-family from New

* This genus, proposed (as Enicodes) by Mr. G. R. Gray, in Griffith’s

translation of Cuvier (Insects, ii. 117), has, so far as I am aware, never

been described. The following are its characters :—

Caledonia, the head of the male is, it is true, even more

dilated, although not in every individual; but the dila-

tation occurs in the very centre of the eye, thrusting

away the lower lobe, which thus becomes completely

separated from the upper. In Tapeina, a very anomalous

genus of this family, the head of the male is broadly

dilated in front, the eye and the base of the antennz

being placed behind the dilatation, the eye however

showing a little of its upper lobe above and of its lower

lobe below.* This remarkable type of structure is also

found in other families of Coleoptera, and where we should

perhaps least expect to see it, as e.g. in Acropis among

the Colydiide, in Apogeniat among the Cisside, and in

Zygenodes among the Anthribide ; its most remarkable

development occurs however in the Dipterous genera

Diopsis and Elaphomyia.

In the female the head of Pascoea is like Sphingnotus,

but strongly narrowed behind the eyes. The only species

known was first detected by Madame Ida Pfeiffer in

Ceram, where it is found on the trunks of fallen trees.

scattered punctures, the centro-basal patch surrounded

with small grayish spots formed by a denser pubescence,

two or three more or less imperfect bands made up of

the same kind of spots behind the middle, apices sub-

sides of the former with patches of grayish pubescence

which are themselves varied with glabrous spots; an-

are truncate on the sutural half and emarginate on

the outside ; the centro-basal patch is also surrounded by

small grayish spots, but these, as well as the bands,

depending on greater density of pubescence, are not to

be relied on for specific characters.

tures scattered, but absent in the centre; scutellum

slightly transverse, nearly round; elytra not broader

at the base than the prothorax, finely and sparsely punc-

tured, two broad yellowish bands dividing them into

three nearly equal portions, an imperfect band at the

cheeks ; prothorax grayish-brown, mottled with dark

brown, coarsely punctured, a slightly elevated line in the

middle anteriorly in the male, less marked in the female ;

elytra less strongly punctured than the prothorax, each

with six slightly raised lines, two of which are a little

more prominent than the others, three or four narrow

waved ashy bands, the basal one indefinite and more or

less broken up and divided ; body beneath and legs ashy,

speckled with pale brown; antenne reddish-brown.

The male of this species has the prothorax much

less dilated than any of the preceding, and the female

shows little more than a rough line on each side.

M. Blanchard’s figure of Z'mesisternus adspersus agrees

tolerably well with P. flewwosa, but his description does

not.

The prothorax is dilated and margined at the sides in

this genus as in Sphingnotus, Polyxo, and Elais, but it is

not spined below the margin, and in this respect it agrees

with Mneside, which again, is a stouter form than Arrhe-

notus, with shorter antenne, the third and fourth joints

of which are not longer than the scape. The females

have the prothorax only very feebly margined ; in the

males, even of the same species, it varies considerably in

breadth. The genus was originally characterized from a

female specimen, and was separated chiefly on account

of its slender antenne and generally weaker figure ; con-

tinued additions to the Z'mesisternine induced me to

unite it to 7’mesisternus as one of its aberrant forms, but

as most of these have been since decribed by M. J.

Thomson, I return to my first idea. Arrhenotus Wallacei,

unlike the 7'mesisterni, delights in the hot sunshine.

limited stripes of pale yellowish or ochraceous pubes-

cence, the stripes sometimes more or less broken up

into spots which are often contiguous, sometimes a

larger spot behind the scutellum, either very distinctly

pubescent, passing into it gradually, or absent altogether ;

elytra less elongate than in A. Wallacei, only the outer

apical mucro well marked, the inner consisting merely of

the sutural angle ; body beneath pubescent at the sides,

varying from ashy to yellow, the central line very glossy ;

legs clear yellow or greenish yellow, often tinged with

reddish, in none of my examples pubescent (or only very

finely so), except on the lower part of the tibie and

tarsi.

Length 5-7 lines.

From the coloration I expected to make out three

species of what, on a careful examination, 1 can now

only regard as one. The breadth of the prothorax in the

male varies considerably ; on the anterior lobe the surface

is finely and obliquely corrugated.

In its broad prothorax this genus resembles Hlais, but

its apex is not emarginate, and its legs are shorter and

nearly equal in length. M.J. Thomson compares it to

Craspedoderus,* which has coarsely facetted eyes, an ex-

ception in its sub-family. In one of my specimens the

prothorax is just as it is described by M. Thomson ; in

the

other it is nearly straight without any rounding an-

teriorly ; in the former the margins of the prothorax are

set

with small black granulations, giving them a sort of

crenulated appearance.

The male of the only species at present composing this

genus has a habit quite distinct from T'mesisternus, and

in its longer and slender legs makes an approach to

Urocalymma.* The female has stouter legs (but scarcely

shorter than the malef), much thicker femora, and a

prothorax more resembling the ordinary 'mesisterni.

From this sex I made my original description, the male

Islands.

being then unknown in our collections. The prothorax

of the male varies much in breadth, as is usually the case

in exceptional dilatations or projections of parts, but it is

strongly and broadly sinuated at the apex, its anterior

angles a little rounded, and then dilating into what may

be called a broad lobe, which, in the female, is replaced

by a stout tooth; at about midway a notch occurs, but

only in the male, and directly below this notch is the

infra-marginal spine; from the middle the sides of the

prothorax are slightly narrowed to the base.

CHRAMBY CIDA.

The remainder of this work, including the Cerambycidee

and Prionide, will be arranged almost entirely after the

method of Prof. Lacordaire, recently published in the

eighth volume of his “Genera,” so far as it goes in the

treatment of the former family. The illustrious author,

returning to the old plan, commences his arrangement

with the Prionide, and ends with the Lamiide: the

Lepturide, after Dr. Leconte, who in this matter has

been followed by M. James Thomson* and myself, being

considered a simple group of Cerambycide. Having be-

gun with the Lamiide, it will here be necessary to take

the Cerambycide before the Prionide.

As all interested in the subject will be in possession of

M. Lacordaire’s volume, it will be unnecessary to do

more here than to show how it is proposed to deal with

his arrangement in applying it to the remainder of the

present work. As in the preceding volumes of the

“Genera” M. Lacordaire makes several subordinate

divisions between the “sub-family” and the genus, such

as tribes, legions, cohorts, &c.; on these I do not propose

to enter, as they are mostly merely names designating

the different stages of a dichotomous classification. His

“ groupes,” however, are truly natural so far as our know-

ledge of the species extends, and the grave difficulties of

the subject admit, and these “groupes” become in our

arrangement, sub-families.

Four remarkable genera, having scarcely anything in

common, except two of them, are first separated as

“Legion 1.” None of these belong to the Malayan

fauna. The true Cerambycidee,—< Legion 2”—includes

two cohorts. The first “ Cerambyeides vrais sylvains”’ are

solely distinguished by the intercoxal process being in

the form of an “elongate triangle, more or less acute,

very rarely short.” This cohort exhausts the eighth

volume, and it will take a large part of the ninth to

complete it. The work being in this respect unfinished,

| * “Essai,” &¢., p. 331. The “Lepturite” formed one of the then

“Legions” of Cerambycide. In the “ Systema” they once more consti-

tute a ‘ tribe” equivalent to the Cerambycide.

any breach of continuity, as it were, M. I

having at once proceeded to divide his cohor

sections—one with strongly, the other with fine

The males appear to have narrower elytra, and nearly

cylindrical abdomens; in the females the latter are more

triangular. There is a very distinct tubercle on each

side of the prothorax in N. tibialis, and it is also pre-

sent although much less distinctly im N. ignavus. In

N. ovatipennis the tubercle is replaced by a broad, but

very slight and scarcely more than perceptible promi-

nence. ‘The antennary tubercles form an almost con-

tinuous projection across the front.

more or less triangular.

+ One of these (Comusia, Thoms.) is not in Mr. Wallace’s collection,

sible from an Obriwm.

M. Perroud’s type (1. filiformis) appears to be a much

narrower insect, and to differ in other respects from the

species described below. In my original description, I

have conveyed an impression which I did not mean to

convey, and to which M. Lacordaire has taken a just ex-

ception. i have said that the coxe of the intermediate

legs are ‘ unusually large, and placed so apart, that the

insertion of the femora can be almost seen from above ;”

it should have been that they are extended so much

towards the sides, that the insertion of the femora can be

almost seen from above. The genus is an abnormal one

even in this sub-family.

its peculiarly narrow outlines and mutic prothorax, it

cannot be generically separated.

M. Lacordaire has founded this genus on a somewhat

remarkable insect in Count Mniszech’s collection, which,

from its cylindrical abdomen I should have been inclined

to consider a female, if the learned Professor had not

stated the contrary. At any rate, in a second species

described below, the abdomen is very much narrowed at

the apex, and this I have very little doubt is a male.

The genus is at once distinguished from all others of its

sub-family by its vertical epipleure.

genus are known from Australia, and several from

Africa.

the apices entire and somewhat rounded ; body beneath,

glossy golden-green ; legs and antenne dark blueish.

In the above work this species was described as having

the apices of its elytra obliquely truncate: this was owing

to their being a little contracted on the sutural side in

my specimen, perhaps from its not being fully mature ;

the corrugated appearance of the prothorax and elytra

is very slight, and is scarcely perceptible, except m cer-

tain lights.

CERAMBYCINA.

“One of the most interesting groups of the Ceram-

bycidee,” says M. Lacordaire, ‘ but the most rebellious

as to classification, owing to the modifications to which

all the most important organs are subject.” And to this

it may be added, that some of the species are liable to a

degradation of size and character which makes their

recognition difficult. The least exceptional characters of

the Cerambycine seem to be—the membranous, deeply

bilobed labium; a generally elongate projecting head,*

* The head is often furnished in front, above the clypeus, by a sort of

*scutcheon or “ plaque ” (plaque frontale, Lacord.); itis formed by a more or

less deeply impressed line surrounding a transversely oval, or nearly oval,

space.

ties open externally ; and prosternum vertically truncate

in this sub-family. Cerambyx is the only * European

* M. Lacordaire says two, including Pachydissus, Newm., to which

Cerambyx Nerii, Er., is referred, and which has been found at Nice. The

extension given by M. Thomson to Pachydissus, in which he has been

followed by M. Lacordaire, is, I venture to think, untenable. The latter

says, ‘‘ the essential character which distinguishes it (Pachydissus) from all

the preceding resides in the lower lobe of the eyes, which advances, more

or less (sometimes scarcely at all—pavfois peu—) below the antennary

tubers.” Among the species, only a part of which were known to M.

Lacordaire, we find associated together are, indutus, venustus, micaceus,

M. Thomson, in proposing this genus, says that it is

perhaps near Pachydissus; im the ‘‘ Systema ” Neoce-

rambyx is confined to C. Paris, Wied., while most of the

species placed originally in the genus are in the second

work ranged under Pachydissus. M. Lacordaire adopts

this arrangement (see ante, p.508,n.). I prefer following

M. Thomson’s earliest idea, subject to the exclusion of

those species,* which he himself afterwards placed in

genera specially formed for their reception. Tvrirachys,

Hope, is near Neocerambyx, but has a spined prothorax.

* These were C. auwripennis, Pascoei, and nervosus.

Hab.—Sarawak.

Dark brown, covered with a close grayish pubescence ;

head with two longitudinal grooves between the eyes,

uniting below; prothorax much narrower than the elytra,

the corrugations rather large, and only slightly intricate

and flexuous; elytra grayish silky, the exterior apical

angle not produced; body beneath, closely pubescent ;

posterior legs only slightly elongate ; antenne very long.

Length 26 lines; of the antenne 66 lines.

I refer this somewhat doubtfully to M. Thomson’s

Aiiueas, since he describes the occiput as having an eleva-

ted longitudinal line, and gives Bengal as its habitat.

M. Lacordaire moreover places it with Hoplocerambya

on account of its spinous antenne; im my specimen,

however, the spines are only slightly developed on the

fifth and sixth joints, and the general appearance of the

insect accords much more with Neocerambyx than with

Hoplocerambyx. In N. textor, it is the female which has

spined antenne, and not the male.

In my former description the facets of the eyes are

said to be small, they are, however, moderately large, as

in most other genera of this sub- -family ; ; 1t 1s necessary

also to explain that the fourth and fifth jomts of the an-

spines. This extraordinary form is at once distinguished

by its twelve-jointed antenne.

of several of the species appear to vary greatly in size,

as well as in some of their characters; in the larger

specimens, for example, the last joint of the antenne is

considerably longer than the preceding one, while in the

smaller ones it scarcely exceeds it.

fillimg up the transverse groove ; prothorax moderately

elongate, the corrugations scarcely flexuous and nearly

entire, the pubescence very short and delicate ; elytra

almost obsoletely punctured, each with three very indis-

also corrugate as in the male; the elytra are much

broader, and have a very decided ovate outline, and the

antenne are much shorter, and, except the scape, not

rugosely punctured.

Mr. Wallace, in his notes, says that this species is

“ abundant under fallen trunks,” nevertheless, no female

is in the collection, and I am, therefore, unable to com-

pare it satisfactorily with the preceding. In the type

specimen, the spines beyond the seventh antennal joint

are obsolete, or nearly so. In another and smaller speci-

men there is no trace of the lines on the elytra.

The antennw of this species—so far as the female is

concerned—are much more strongly dilated than in the

last, and the second and third joints, although much

and more rounded at the sides; but in other essential

characters it is sufficiently similar to be, for the present

and until the other sex is known, placed in this genus,

My specimen of the type of this genus (J. lineatus) is

a female, but judging from the male of I. ephebus, there

does not appear to be any difference between the sexes,

except that the antenne of the male are a little less

serrate ; M. Lacordaire does not admit this genus, not

seeing any essential difference between it and “Dymasius,

Thoms., which is unknown to me, but from his deserip-

tion, it appears that the posterior tarsi of the latter have

an elongate basal joint, or at least a joint longer than

the second and third together; and the antenns have

the third joint equal to the fourth and fifth taken together.

After this I cannot agree that the two genera should be

united. I think, however, that I. strigosus should be

removed from Jmbrius, as with the posterior tarsi of the

present genus it has the antenne of Dymasius, and differs

from both in its truncate elytra, The genus will then consist

of three homogeneous species: 1 have a fourth unpub-

lished, from Malacca; obtained, I believe, from the

Count F. de Castelnau’s collection,

A genus, M. Lacordaire says, scarcely distinct from

Dymasius, the latter name some years posterior to Cal-

pazia. Dymasius strigosus, Thoms., the type, appears to

be a rather large insect, with a very long narrow body,

covered with a fine silky pubescence ; the third joint of

the antennz as long as the two next together ; and the

tarsi elongate, the first jot of the posterior being longer

than the second and third together. These and the dif-

ferential characters given by M. Lacordaire himself,

seem to my mind to be decisive as to the genuineness

of M. Thomson’s genus. The posterior femora nearly

extending to the extremity of the elytra is another, but

perhaps secondary, character of Ca/pazia. This arises

partly from the shortness of the body, and partly from

the length of the meso- and meta-sterna, the imsertion

of the femora being thus very far back. The female is

unknown.

The finely granulate eyes of this genus, combined with

the form of the antennz, will readily distinguish it from

all others of its group. M. Thomson by aslip of the pen,

says the femora are not clavate, and that the rounded

apex of the suture of the elytra is bispinous. In numer-

ous examples now before me they are as stated above.

In some specimens the antennze of the male are scarcely

so long as the body, and in the female they are only a

little shorter.

I was formerly content to place the only known species

of this genus with Xoanodera, but if I had not been

otherwise convinced of my error, M. Lacordaire’s more

stringent definition would have made it impossible to

retain it there. The characters of the elytra and of the

femora exclude it, as well as those of the antenne, sterna,

tarsi, &c., and the anterior cotyloid cavities are narrowly

closed behind. M. Lacordaire, not having seen the

species, appears to think that it may belong to Rhytido-

dera ; and he states that there exists another nearly allied

from the Moluccas and Laos.

The female differs, according to M. Lacordaire, only in

having the antenne a very little longer than the body.

To this genus I now refer my Zatrephus inscitus,* although

somewhat different in sculpture and pubescence. The lat-

ter was described from a female,and has the antenne much

shorter than the body, and more dilated than in X.

trigona (), the dilatation commencing with the sixth

jomt. The inner maxillary lobe in the typical species is

very long, inserted on the upper part of the maxillary

plate, bent at the base, and then crossing the outer lobe

between it and the mandible, and passing outwardly

and beyond the mouth, so as to assume the position of

the outer lobe ; at the apex it is dilated, and fringed

with longish hairs as in the Callichromine. The maxil-

lary palpus is borne on an unusually long pedicel.

Neither of these characters appears to be present in X.

inscita.

HEspPrrRoPHANINE.

Four genera of this sub-family are found in the Ma-

layan Archipelago. They all belong to the division

having the prothorax without the lateral spine. Their

diagnostic characters, according to M. Lacordaire, con-

sist in having the anterior coxe transversely oval or

subglobose, and the intermediate cotyloid cavities open

externally. The head is only slightly prominent, very

short in front, with large eyes; the prothorax large,

often tuberculate above; the elytra shghtly exceeding

the prothorax at the base; the prosternum rounded be-

hind; the body elongate and pubescent. The species

are disseminated over the world; Hesperophanes and

Stromatium are the only representatives of the sub-family

in Europe.

M. Lacordaire divides this genus inte two sections,

according as the male has the prothorax furnished with a

tomentose depressed patch on each side or not. . I find

it, however, in all the species he has enumerated except

S. hirtum, L. Fairm., which is unknown to me. In SV.

asperulum and the new species here described, the pro-

thorax is rounded at the sides, the patch in question being

mostly underneath; in the others the sides are straight,

and the patch is visible from above. No other instance

of such a structure occurs, I believe, among the Coleop-

tera, and its use is unknown. ‘The patch is always large

and well limited, and densely tomentose.* Solenophorus,

Muls., was founded on the female of 8. unicolor.

* The European S. wnicolor, Ol., is found at Rio Janeiro—possibly in-

troduced. My S. alienwm, from Espirit Santo, is closely allied and may

be the same, but, inter alia, the prothorax is so much narrower, and the

sides are so much straighter, that I think no Entomologist would unite

them until intermediate forms shall be found to demonstrate their identity.

To these characters M. Lacordaire adds, inter alia, the

antennary tubers produced into a short cone at the apex,

but this is also the case in Stromatium; elytra unarmed

at the extremity, to which, however, Z. maculatus is an

exception; * and as a secondary character, that these

organs constantly present a design which is foreign to

Stromatiwm, and which gives the species a different

physionomy. The union of the antennary tubers at the

base creates a prominent uninterrupted fold; between

the eyes, which is wanting in Stromatiwm. Zoodes macu-

latus, White, a Ceylonese species, varies greatly in size,

and the males are very much more bulky than the females.

The latter peculiarity seems also to be the case with Z.

cornutus, according to M. Lacordaire, but of this I have

only seen the male—the specimen here described, which

seems to differ shghtly in colour from the type.

Mr. Newman can scarcely be held to have characterized

this genus, ‘its slender and graceful form, its suddenly

incrassated femora, and the gaiety of its colours,” being

all that he has said of it; and such a flippant manner has

indisposed Entomologists to adopt the name which he has

“suggested.” Mr. Newman, however, wrote in times

when such a loose method was more tolerated than it

would be now, and as Mr. Hope’s definition was not

much more to the purpose, I think, on the ground of

priority, we should adopt Mr. Newman’s name. It must

be recollected that there can be no doubt about the

species intended, as Stenocorus biguttatus is given as the

type, and of this Donovan gives a very good figure.

* M. Lacordaire, in a note (viii. 307), says that the genus Atesta has

the elytra ‘‘ manifestly truncate’ at the apex, not rounded as I have

stated; and that Coptocercus unifasciatus, Hope, forming one of the

species of my genus Allotisis has the joints of the antenne, from the third

to the ninth, according to Hope’s figures, furnished with short spines,

not the third and fourth only. I can only maintain and repeat here what

I have stated in proposing those genera.

CALLIDIOPSIN #.

Like the Cerambycine this sub-family is subject to such

modifications of structure that it is difficult to limit the

genera satisfactorily, and it is as difficult to limit deci-

sively the sub-family itself. According to M. Lacordaire,

it is extremely near the Hliginodermine, and he separates

it rather because of the habit of the species, which is very

different in the two groups, than from any dependable

technical character. Generally it may be said that the

head is small, not prominent, short in front, with the

antennary tubers depressed or sometimes obsolete ; the

lower lobe of the eyes large, generally close to the man-

dibles ; the latter short and pointed ; antennze pubescent,

villous and unarmed ; prothorax oval or cylindrical, rarely

tubercled ; anterior coxee globose, with their cotyloid

cavities open behind, and the intermediate closed in.

Some of the species are yellowish varied with dark brown

or black, and others—especially most of those here de-

scribed—are brown of various shades, with a pubescence

consisting of gray decumbent hairs placed apart, and at

regular distances. With the exception of four American

genera, including one from the West Indies,* and one

from Réunion, all the others are natives of Australasia

ever, belong to the former. *

This species differs from Ceresium in its short broad

face, and in the third jomt of its antenne being twice

as long as the fourth, instead of only a little longer (or

as in OC. vestigiale not longer). Its habit, however, is

quite the same as Ceresiwm, and for the present I leave

it in the genus as an abnormal species.

Since M. Lacordaire has made the relative thickness of

the femora the starting point of his tabulation of the

genera of this sub-family, I have been compelled to adopt

this genus which I[ had formerly held to be synonymous

with Ceresium. The difference, like that of the anten-

nary tubers, is comparative, well marked in extreme

forms, but passing insensibly into one another. In D.

albifrons the scape is exceptional, being rather pyriform

than cylindrical. The type, D. simplex, does not seem

to have been found by Mr. Wallace.

In the unique male insect in my collection, the terminal

joint of the maxillary palpi is rather singular, the

slightly triangular, as in the same sex of the rest of the

difierent from anything else in the sub-family; in other

respects ‘’ethionea seems to be the genus to which it

its proportions, and differs more particularly in not

having any antennary tubers, and the consequent absence

of the deep depression below them which characterizes

Tethionea.

STRONGYLURINE.

A single specimen of a rare and very remarkable insect

constitutes the only Malayan representative obtained by

Mr. Wallace, of this almost purely Australian sub-family.

A second example in the Darmstadt Cabinet was de-

scribed by Dr. Kaup, and a third, which served M.

Lacordaire for his description, is in the possession of

Count Mniszech. The female is unknown.

The principal character of the Strongylwrine is the

possession of a muzzle, but this is wanting in the

Malayan genus ; the sub-family is then known, according

to M. Lacordaire, by the antennz being flabellate in the

males, and by a peculiar structure of the mesosternum ;

from its nearest Malayan allies it is distinguished by the

enclosure of its anterior cotyloid cavities. Of the ten

genera eight are Australian. Another remarkable

genus (Heterolepis, Lacord.) is from New Caledonia ;

its single species, H. tnvesisternoides, is covered with

scales, without any admixture of hairs, except beneath ;

it is the only known instance of this kind of vestiture

among the Longicorns.

There is nothing more fantastically remarkable among

the Longicorns than the antenne of the insect before

me. ‘The first prolongation from the third joint is nearly

an inch long, very slender and filiform, and most regu-

larly frmged, apparently on all sides, with very slender

hairs ; these prolongations, all exactly of the same

character, gradually shorten to the tenth joint, where it is

eight lines in leneth, and the eleventh joint, resembling

one of the prolongations but a little thicker, is six lines

in length. In other respects the insect has a strong

family resemblance to Strongylurus. It was taken by

Mr. Wallace in the town of Menado, at lamp-light.

OBRIIN 2%.

A small sub-family, limited, according to M. Lacor-

daire’s arrangement, to three genera, Obriwm, Stenho-

malus,and Longipalous ; ‘and recognizable by the length

and narrowness of the prothorax, the size of the first

abdominal seement, and the pecular habit of the

species.” In the female, in all those species which are

known, the very large basal segment of the abdomen is

followed by segments which (although the second and

sometimes the last appear very nearly in the normal

state) are very short, more or less hairy, and depressed

or forming a shallow excavation. I am by no means

sure, however, that this peculiar structure is confined to

the females, at least in all the species; or that it is not

in some degree participated in by the males. But the

insects are very scarce in collections, and it is difficult

to ascertain the sexes. There are two genera in Mr,

Wallace’s collection, one perfectly new, and the repre-

sentative of the other 1 refer, with a slight shade of

doubt, owing to the uncertainty of the sex, to Obrium.

I have two specimens of the svecies described below,

but am not certain as to the sex of either. One, from its

longer antenne, appears to be a male, but it has a mo-

derately sized abdomen, with the first sezment twice the

size of the second, and all of them with a broad hairy

patch along the middle. The other (with imperfect an-

tenne) has an exceedingly small conical abdomen, not

longer than the metasternum, slightly hairy only along

the middle, and with the last three segments very much

smaller than in the former specimen. When better under-

stood, the species will probably require to be separated

from Obriwm. There are two more species (imperfect),

apparently both males, in the collection ; one from Sara-

wak, with the ninth joint of the antenne entirely white;

the other from Mysol, with the antennez dark brown, at

least so far as the ninth joint.

The habit of the only species of this genus is that of

Tillomorpha lineoligera, near which I had casually placed

it, but an examination of its anterior coxe and the struc-

ture of its abdomen shows that its true place is with

Obrium and its allies. The sculpture of the prothorax

resembles that of Huderces, one of the Clytine. There

is only one specimen in the collection.

punctured, the punctures gradually disappearing towards

the apex, near the middle a short transverse patch com-

The second section, containing those species with the

eyes finely granulate, includes the great bulk of the

Cerambycide, which are placed in M. Lacordaire’s

arrangement in three divisions: the first two and the

last depend for their differentiation on the point of inser-

tion of the antennz, and the second, which contains

no Malayan species, scarcely merits—according to our

author—separation from the first. The number of sub-

families in this section, which includes the remainder of

the Cerambycide, represented in Mr. Wallace’s collection,

amounts to sixteen, out of the fifty-four ‘‘ groupes” into

which M. Lacordaire divides it. The following table

exhibits the principal characters on which the subfamilies

are based.

There is only one species from the Island of Morty

representing this (otherwise with one other exception)

purely Australian group, and some other groups nearly

related, most of which I have hitherto treated as Steno-

derine. The principal diagnostic character of the sub-

family is the small round eye. The Malayan representa-

tive belongs to Syllitus, which forms an exception to all

its allies, inasmuch as the eyes are coarsely granulate ;

the species is quite new, and bears a striking resemblance

to the Chilian Syllitus pseudocupes.

in the latter respect, and generally in habit—trusting to

Chilian S. pseudocupes than to the Australian species.

antenne black, shining, rest of the joimts yellowish, all

except the last three or four very hairy beneath in the

male.

LEPTURINA.

This subfamily, as limited by M. Lacordaire, is one of

the largest and most natural of all the Cerambycide. The

species, which abound in the temperate parts of the

Northern hemisphere, are easily recognized by their

peculiar habit, due in great part to the head being pro-

longed behind into a neck. They are found chiefly on

flowers, and do not appear to be very active. The

tropical species are comparatively few in number, but-

doubtless many more remain to be discovered, especially

in the Malayan region; there is no evidence as yet of

their being found in Australia. Mr. Wallace’s collection

contains two undoubted species of Leptwra, and I have

seen another species from Penang; there are also repre-

sentatives of three purely Malayan forms. A fourth

Malayan genus (Asilaris, Pasc.) is known, but does not

appear in the collection.

was taken flying in the jungle at sunset. Another species,

from Ceylon, is in the collection of Mr. W. Wilson

Saunders.

~ In this remarkable genus I have placed a much smaller

species (CO. capreola), from Penang, which M. Lacordaire

seems to think is generically different. On a re-examina-

tion, however, I find that, except that the head is a little

shorter, the shoulders not toothed, the apices of the elytra

not spined, and the antenne a little longer, there are no

other than purely specific differences, and those enu-

merated are scarcely of sufficient importance to justify

another generic name, as the two species, although dif-

ferent in colour, are evidently almost identical in habit.

Of this great and truly northern genus, the two species

the tropic of Cancer that have been published. They are

true Lepture, and in colouration generally and habit they

approach [. 12-guttata, Fabr. Mr. Wallace seems to

have found only a single individual of each species. Mr.

Lamb has found a single imperfect specimen of a third

species at Penang.

oides differs, perhaps generically, in having nearly cylin-

drical antenne, still with joints a little dilated at the

apex. Another allied species is imperfect, wanting the

hind legs, and therefore I have not described it. Kphies

appears to be the Malayan representative of Huryptera.

They are all covered with a not very decumbent pubes-

cence, which is especially dense on the elytra.

A second species which I have added to this genus is so

far aberrant as to cause M. Lacordaire to divide Dejanira

into two sections, the first or typical form (D. quadri-

punctata), the only one we have to deal with here, being

distinguished by its elytra rounded at the apex and its

sutural angle spined, the posterior femora with two teeth

at the apex, and the mesosternum and prosternum tuber-

culate. These characters are absent in D. biapiculata.

Mo.orcHin#.

Some of the genera of this subfamily (Hephestion,

Sphecogaster, Callisphyris) are among the most striking

of the Cerambycide, but its representative in Malaisia

(Thranius) has a common-place appearance enough, and

seems to me a rather aberrant form of the group.

Molorchus * major is a well-known European species, and

M. ulmi closely resembles it; all the rest are American

—North and South. The principal characters of the

Molorchine are the imperfection of the elytra, the pe-

culiar wasp-like form of the abdomen, and the conical

anterior Coxe.

wards associated major. The latter was subsequently placed by Fabricius

at the head of his Molorchus, and the term Necydalis applied to the

heteromerous @demere of Olivier. M. Mulsant, in separating major from

minor, reversed the right appropriation of the two names; and, as usual,

one author copies another. For further remarks see Ann. and Mag. Nat.

A Ceylonese species (Z'. gibbosus) is the type of this

genus, the species of which are found as far south as

New Guinea.* The males have not been known

hitherto ; one, however, of that sex, if I am not mistaken,

is described below, and differs very little from, but is,

perhaps, a little narrower than, the female. M. Lacor-

daire suspects that Olivier’s Necydalis nigricornis (No. 74,

pl. i. f. 8) is congeneric ; I believe, however, that I have

identified this with a common South-African insect allied

to Phytecia.t None of the species here described have

that gibbosity of the prothorax which distinguishes the

type; all, except 7’. basalis, have a large white ring on

the antenne; of the remainder 7’. angustipennis has de-

hiscent elytra; J’. bimaculatus has a pale transverse spot

on the middle of each elytron, while in 7’. brunneus the

elytra are unicolorous.

NEcYDALINA.

Necydalis* minor, Linn., is the type of this subfamily,

which, absent from South America, is moderately repre-

sented in Europe, more extensively in Malaisia, and

sparingly in North America, Australia, and South Africa.

It differs from the Molorchine in its entire anterior coty-

loid cavities with their coxe rarely exserted, and then

more or less transverse ; but the form and prominence

of the anterior coxze are both frequently questions of

degree, as I have, in many instances, pointed out.

The possession of a male of L. discolor has enabled me

to give the generic characters of that sex, and to show

that hitherto we have only known the females, and not

the males, as M. Lacordaire has doubtfully assumed.

This genus is the only one in the subfamily with its head

not exserted. HH. singaporensis, according to Mr.

Wallace’s notes, fly about lke small bees, while H. sara-

wackensis are found crawling on timber, and in such situa-

tions are “ hardly distinguishable from ants.” Two more

species from Amboyna and Mysol respectively are in the

collection, but are not in a condition for description.

margins, in the prosternum and mesosternum being

nearly on the same plane, the former broad and the latter

truncate behind, in the rounded intercoxal process, and

the short broad porrect head without any frontal im-

pression, and the eyes nearly entirely divided. On the

other hand, it has the same habit and coloration, as well

as the same remarkable structure of the abdomen, and

denticulate posterior tibie.

The species of this genus appear to be exceedingly

rare, Mr. Wallace’s captures being mostly uniques; I

have therefore been able to pair only one of them, M.

subulata, and in it I find the abnormal structure of the

abdomen common to both male and female, the only dif-

ferences between the sexes being that the male has the

Longicornia Malayana. 571

posterior femora pedunculate, the clavate portion swelling

out into a large oval hispid knob, and the imner spur of

their tibiz strongly produced. But in M. flavitarsis (9)

the spur is nearly as much developed, while the femora,

although strongly clavate, are not pedunculate. Another

point worth noticing is that the external maxillary lobe

is exserted, as in many of the Callichromine, but in the

female of M. subulata, which I have dissected, it is

apparently of the normal character; it may be, however,

that there is a voluntary power of lengthening or short-

ening it. The large triangular impression formed

directly above the clypeus, the apex extending upwards

between the eyes, is often accompanied by a -shaped

impression at the bottom of the cavity. The punctua-

tion is very similar among the species, fine, irregular,

and scattered on the head and prothorax, and coarser

and equally irregular on the elytra, these latter organs

having a sparse transverse pubescence. ‘The species are

found flying slowly about newly fallen timber. They

have a geographical range extending from Northern

India (M. Indicus, Hope) to New Guinea (M. flavitarsis).

Characteres ut in Merioneda, sed abdomen normale.

In the unique example before me on which I have

founded this genus, there is no trace of the peculiar

structure common, I believe, to both sexes of Merio-

needa, but in other respects, with one exception, there is

no difference. The exception may be only of sexual or

perhaps of specific value; it is that the imtermediate

tarsi are unusually broad, the basal joimt being equi-

laterally triangular, with the two following transversely

dilated. The posterior femora are but moderately cla-

vate, and their tibie are straight as in Merioneda subu-

lata, and furnished with a tolerably long inner spur. It

is, probably, a female.

This description will apply to both sexes, so far as I

am able to judge from an example of the male of P. car-

of the elytra in the male, while in the female, they do

not go beyond half the length, and are more broadly

dilated. There are eight species described, only one of

which was found by Mr. Wallace. Wherever they occur

they appear to be amongst the rarest of Longicorns.

The insects of this subfamily are distinguished by

having very distinct epipleurz to their elytra throughout

their whole length, but the other characters, except the

marked elongation of the hind-legs, are less constant.

They are all of an intense black colour, more or less

relieved with bands or stripes formed by a dense whitish

pubescence. They are natives of Asia, but have not

been found in India, although two species are known

from North China; nor have they been met with south

of Borneo.

males, so far as I can see, except that the elytra are a

little narrower, or rather more parallel posteriorly. I have

described six species from Penang (Proc. Zool. Soc. 1866,

joints of the antennz fulvous-yellow. In two or three of

them the carina passing from the shoulder backwards

disappears or becomes scarcely perceptible.

occurred to my knowledge at Penang.

The species described below I first referred doubtfully

to Blemmya, and subsequently proposed to constitute it

a distinct genus. M. Lacordaire, however, considers it

to be only a degraded form of Prothema. The two spe-

cimens before me, are, I believe, from the comparative

shortness and dilatation of their antenne, females; on

the other hand, the two original species of Prothema in

my collection have the antennze longer than the body,

and much less dilated, and the basal segment of the

abdomen not nearly so large relatively to the other seg-

ments ; hence they are probably males.

The size of the abdominal segments of this genus

is exceptional, yet having regard to the habit, and to

the presence of epipleure of the elytra, there can be

little hesitation in placing it near Prothema. As in that

genus, the males—now unknown—will probably be found

to have dilated antennz. The third joint of those organs

terminating in a slender obtuse process, and the shortness

of the joint itself compared to the fourth, are also charac-

ters which, although probably only of generic value, are

nevertheless foreign to the Prothemine.

CALLICHROMIN#.

The species of this subfamily in the collection are com-

prised in two genera out of the twenty-nine enumerated

by M. Lacordaire. Of these two genera I have described

here twenty-two species, leaving a few not so well-marked

for future consideration. There is a strong resemblance

between many of the species, and their discrimination,

in many cases, is very difficult. They are nearly all very

handsome, mostly bright metallic-green, and emit an

agreeable odour, due to certain glands situate behind

the posterior angles of the metasternum, and communi-

cating by pores with the surface. Two species are found

in Europe, a few only: in America, the remainder are

African and Asiatic; none in Australia. *

* Mr. White has described a ‘‘Callichroma Cinderella” from ‘‘ Aus-

tralia (N. E. Coast) (Coll. Dring),” but this locality requires corroboration.

in habit as well as in geographical distribution.

Caput antice angustatum et paulo productum. Mandi-

bule elongate. Antenne ( ¢) corpore vix longiores,

The comparative shortness of the antenne, and the

greater length of the third joint, give the males, at least,

of this genus a somewhat different style to those of

Chloridolum. Another character, which seems tolerably

constant, is the narrowness of the head beyond the eyes,

and the consequent approximation of the mandibles at

the base ; this confers a lengthened outline on the muzzle

which is not manifest in the other genus. M. Lacordaire

divides Leontium into two sections :—(1) Joints of an-

tenne from 5-10 shortly spined, &c.:—(2) Joints 5-10

angulate at the apex within, &c. There is one species

of each section in the collection.

intensity according to the light, but the outer with a

blueish tinge; body beneath dull greenish, with a fine

dense silvery pubescence; fore-legs green with blue

reflections, the intermediate and posterior entirely dark

chalybeate-blue, tibize of the latter much dilated, their

tarsi with the basal joint scarcely longer than the two

next together ; antennz dark blue, the fifth to the tenth

CLYTINA.

In none of the groups of the Cerambycide is there a

greater change made than in the limitation which Pro-

fessor Lacordaire has given to the Clytine. He has laid

down three characters by which they may be distin-

guished, and ‘‘ the absence of a single one of these

determines that the species is alien to the group, what-

ever may be its habit.” ‘These characters are, (1)—The

antenne extending at the most very little beyond the base

598 Longicornia Malayana.

of the elytra;* (2)—The prothorax unarmed; and (3)—

The basal joint of the posterior tarsi at least a third longer

than the two next together. It is also necessary that the

anterior cotyloid cavities be open behind, and those of

the intermediate angulate outwardly. Even thus limited,

the Clytine are one of the largest and most dispersed of

all the subfamilies of Longicorns. They are mostly

active, gaily-coloured insects, frequently with limes or

bands of yellow or white on a dark ground, sometimes

forming a pattern of complicated character very difficult

to describe.

The type is Clytus arietis, Linn. The following species

shows no close affinity to any other known to me.

scending to near the middle, then curving upwards

and terminating near the shoulder, a little before the

middle a narrow slightly arched "pand, and another

broader one midway between it and the apex, yellowish ;

body beneath ashy, the three last abdominal segments

The differences between Clytus and Clytanthus are

scarcely definable, but in the former the prothorax is

more decidedly globular, and the posterior tarsi have

the basal joint three or nearly four times as long as the

twonexttogether. Olytanthus is avery large genus, and

is found all over the world, except South America. The

type is the Mexican (C. tricolor, but CO. verbasci, Linn. (C.

entire, the fourth apical; body beneath ashy, the sides

varied with white, three intermediate abdominal segments

black at the base ; legs ashy-black, tarsi tinged with ferru-

its fellow an angle towards the scutellum, the third

narrow and transverse; body beneath ashy, with the three

apical segments of the abdomen black; legs black, the

tarsi obscurely ashy ; antennz black, paler outwardly.

An imperfect specimen from Malacca might be placed

here; the elytra are three-banded, the first band formed

by a short semilunar spot on each side of the suture, the

third apical and very broad, the upper part white, the lower

dull ashy; the antenne must have been very nearly as

long as the body.

614 Longicorma Malayana.

The absence of the epipleure or deflected sides of the

elytra, except at the base, distinguishes this genus from

all others of the Clytine. The scutellum also from its

narrowness and length is very peculiar. Having both

sexes of the two species here described, I find the female

differs only in its larger size and more globose pro-

thorax.

Length 6-8 lines.

In the pattern of its coloration this resembles the last,

except that the first segment of the abdomen has a yel-

lowish glabrous base, and that all the femora and tibize

are reddish; the broader prothorax and more obliquely

truncate elytra also distinguish it.

The females have the antenne much starters and fre-

Head and prothorax grayish, the latter with two black

spots in the middle; elytra dark brown, or often reddish-

brown, with four gray or reddish-gray bands, the first

sometimes nearly obsolete, or represented by a small spot,

the second oblique on each side, the third broader and

also oblique, very often interrupted at the suture, apices

obliquely truncate, with a slender spine at the outer angle ;

body mostly white; legs reddish-luteous, the tibiz and

tarsi darker; antennez reddish-brown, with the interme-

diate joints whitish.

This species is a variable one in size and colour. It

is said to occur also in Australia. M. Chevrolat is in-

clined to refer to it C. trizonatus, Blanch., as well as

his own P. femoralis, which he thinks is “ perhaps a local

variety.”

the first basal, the second curved upwards nearly to the

scutellum, the third transversely triangular, the last form-

ing an oblique patch at each apex, the latter emarginate,

and shortly toothed at each angle; body beneath grayish-

white; femora and tibie black, tarsi ferruginous; an-

tenne with the first six joints brown, the remainder

whitish, joints 7-10 a little produced on one side at the

apex.

Length 5 lines.

Differs from P. a-litera, Chev., principally (so far as

I can judge from the description) in being without the

two black bands on the breast, and the five on the abdo-

men, and also in the coloration of the antennze. The

“letter” at the base in the above species is an Italic a,

description implies the former.

the last from the three following.

ashy bands, the first basal, the second curved upwards

but scarcely touching the scutellum, the third triangular,

the fourth apical and oblique at its anterior border, apices

shightly rounded, toothed at the outer angle, not spimed ;

body beneath pale ashy, the last three segments of the

external angle smaller; the greatest difference, however,

which is doubtless specific, is in the much shorter pos-

terior tarsi, which at once strikes the observer. My

specimens, judging chiefly from the length of the pos-

terior femora, appear to be males. The shortness of the

antennee is remarkable.

second a curved line directed upwards and meeting at the

suture, the third shghtly triangular, the fourth an oblique

patch close to the suture; body beneath ashy, the last

three segments blackish; legs blackish, the tarsi and

antennee pale brown; in one specimer the sixth and

seventh joints of the antenne paler than the rest.

femora reddish-testaceous ; antenne brownish-testaceous,

washed with pale blue, the scape black.

The two following genera have been omitted by M.

Lacordaire. One of them, Acrocyrta, is expressly ex-

cluded from the Clytine (p. 58, note) on account of the

length of its antenne, but as it has the intermediate coty-

loid cavities angulate, it cannot be placed with either the

Heteropsine or Rhopalophorine, to both of which itisallied.

The other genus, Demonaz, has latterly been referred by

its author to Acrocyrta, but I think it is quite distinct.

For the present, I am content to place them at the end

of the Clytine.

As I have already stated, M. Thomson, in his latest

work (Syst. Ceramb. p. 191), unites this genus to Acro-

cyrta, from which it appears to me to be essentially dif-

ferentiated by the form of its antenne (the joits not

thickened or clavate at the tips, as in Acrocyrta), the

longer elytra, and the different habit. The genus

thus limited contains a number of species, the greater

part sufficiently homogeneous, but including at present

two or three forms which I hesitate to propose as genera

in the absence, in the limited number of specimens be-

fore me, of any trenchant characters that can be relied

on as permanent, although they evidently belong to

distinct natural groups.

bands takes the form of the letter W, or rather of two

VV’s, the interruption occurring where the apex of the

triangle of the second band joins the scutellum.

differ principally in habit, in their small and delicate

dually (although slightly) thicker outwards, with the

terminal joint ovate.

have to be separated from Demonax.

different in coloration from all their congeners, and

having the prothorax broad and strongly rounded at the

sides. I originally intended to place them in a distinct

genus, but as each is represented only by a single indivi-

dual, the former judging from the abdomen a female, the

latter a male, the data for such a step are scarcely suffi-

cient.

The antennz are scarcely so long as the body in the

in his “ Clytides d’ Asie,” has placed six species in this

genus besides the type. For me,so far as I know them,

they belong to Demonax. The latter genus he retains,

but he has given no reasons for doing so.

This is one of those subfamilies separated by M. Lacor-

which it is decisively differentiated by the interme-

diate cotyloid cavities being closed externally. Besides

the Malayan species, there are several others found in

America and Australia, and one in Hong-Kong.

There is no character among the Longicorns subject to

fewer exceptions than the shortness of the second joint

of the antennz, but in this genus it is only about a third

less in length than the following joint, which on the con-

trary is very frequently the longest. In another respect

the antenne are approximate to those of the last genus,

in that they are gradually thickened towards the apex.

The habit of the genus is more with Ipomoria than Hpi-

pedocera, but with the latter it appears to be more closely

allied, on account of the nearly entire eyes.

methocoides,* has a more ovate prothorax (7. e. rounded

at the sides and broader than the head), the elytra much

shorter, chesnut-brown at the base, with a reflexed longi-

tudinally compressed spine or tubercle near the shoulder ;

the elytra also are somewhat enlarged or inflated pos-

teriorly. The genus seems to me to be a very doubtful

member of the Cerambycide.

SESTYRINA.

Two Malayan genera, only one of which, however, is

represented in Mr. Wallace’s collection, and each com-

prising a single species, constitute this subfamily. Its

special character lies in the form of the head, which

is large compared to the prothorax, and is abruptly

contracted behind; the eyes are large and prominent,

and deeply emarginate; the prothorax is very long, and

the body slender. The sexes are unknown, as only one

individual of each of the two species has been hitherto

detected.

* M. Lacordaire, partially misled probably by the phrase ‘‘ head parallel

-with the thorax,” intended to apply to the side, not to the upper part, has

assumed that the head is not perpendicular, and on that account, in con-

junction with the different form of the elytra, is inclined to consider

C. Westwoodii as generically distinct.

The resemblance between this and the Cicindelideous

of the insect is such, that M. Lacordaire considers it one

of the most remarkable Longicorns known. To me it

seems allied to Ametrocephala and Zoédia, but our great

authority intercalates a very large number of genera be-

which is spread over all parts of the world except

Europe; nor does it appear to have any trenchant cha-

the intention of uniting it with the Rhopalophorine, from

which it differs only in the shorter and less setaceous

antenne.

the difference probably is sexual, the longer femora

white ring on the antenne; in other respects it accords

GLAUCYTINE.

Glaucytes has been usually referred to the neighbour-

hood of ‘T'mesisternus, apparently because Latreille

placed it close to that genus, together with two other

anomalous forms, but without any intention of indicating

an affinity. When treating of the Tmesisternine, I

pointed out in a note (ante, p. 440) that it belonged to

the Cerambycide, without, however, any attempt to fix

its position; this, M. Lacordaire says, is so near the

Rhopalophorine, that, except for the size and form of the

eye, he should have included it in that subfamily. The

geographical distribution of the Glaucytine is peculiar,

greater part of the Stenaspidine are American, but

elytra pale pubescent; scutellum black; femora glossy

ferruginous; tibiz and tarsi black; antennze with the

having a rough appearance under the lens; the joints of

the antennz, from the fourth inclusive, much broader

than in L, mawillosus.

This is a very variable species in regard to colour; of

fifteen individuals I have had under examination, no two

were alike. As a species it is distinguished from H. maa-

illosus by its strongly dilated antennze and the stoutness

of the tibie, particularly of the posterior pair. The male

The antennz are, probably, in the early life of these

insects, always fringed with long hairs, but in the majority

of individuals they are bare, or nearly so. M. Lacordaire

thinks the fringe may be a characteristic of the males, but

two of my specimens, which from the more slender and in-

curved abdomen, at least towards the apex, I regard as

Longicornia Malayana. 657

belonging to that sex, have no vestige of it. These speci-

mens are also furnished with a rather long vertical spine

on each side of the mesosternum, close to the edge of

the cotyloid cavity; they are of a pale yellow colour,

and contrast strongly with the deep blue of the under

surface.

scutellum somewhat quadrate; elytra coarsely seriate-

punctate, the punctures terminating abruptly within a third

of the apex, the latter rounded ; body beneath, and legs,

M. Lacordaire’s second cohort “ Cerambycides vrais

souterrains,” includes two subfamilies—Apatophysinc, and

Vesperine. Only the-first of these possesses a Malayan

form, T’rypogceus, described by M. Lacordaire from a

female example in the collection of Count Mniszech, which

he names J’. albicornis. It has a short thick Toxotus-like

habit, and is covered with a silky golden down; the

antenne black, with the first and second joints fulvous,

and the ninth, tenth, and eleventh white; the abdomen

with numerous bright luteous spots.

PRIONIDA. >

M. James Thomson, in his Systema Cerambycidarum,

divides the Longicorns, which for him, as for M. Lacor-

‘daire and other authors, are simply a “ family,” * into five

tribes, the last being the Prionide; and outside the

longicorns altogether, he establishes six additional, and

what he denominates “limitrophal,” families. M. Lacor-

daire adopts this arrangement to a certain extent, but

excluding T'rictenotomide, which he agrees in considering

a distinct family, he places all the others, except Thau-

maside, Thoms., in his “ Legion” of ‘ Prionides aber-

rants,’ together with “ Cantharocnémides” and “ Scéléo-

canthides,” which M. Thomson combined to form his

second section of Prionidw. I confess I think M.Thom-

son’s arrangement the more natural, and that it is more

consistent with the principles of limitation applied to the

* On what principle are the Phalacride separated from the Nitidulide,

or the Ptinide from the Bostrichide, and so on, as families, if the La-.

miide, or the Prionide, have no higher rank than a “tribe”? It is

true that M. Lacordaire thinks that the three primary groups of longicorns

are sufficiently important to be raised to the rank of subfamilies (here used

for the first time in the ‘‘ Genera’’), the subfamily being, with him, above

the legion or tribe; and the “tribe” is afterwards confined to the aberrant

forms of Prionidw.

cephalus, Parandra, &c., from the Longicorns.

Of M. Lacordaire’s second legion “ Prionides vrais,”

we have only to do with his second ‘“ Cohorte,” the

“ Prionides vrais sylvains,” no example of “ Prionides vrais

souterrains”’ being contained in Mr. Wallace’s collection.

Xivuthrus, the Malayan representative of this sub-

family, is considered by M. Lacordaire to be a very

ambiguous form, but he has followed M. Thomson in

classing it with Ctenoscelis and its allies, all natives of

America. I now add a second genus.

Out of ten specimens, exclusive of the one in the

British Museum, I was at first imclined to consider

four as representatives of so many distinct species,

but after a careful examination, I can find nothing

positive in any of them. They all differ among them-

selves, but the differences are those of sex or of degree,

not even of locality, and are apparently individual rather

than specific. The greatest discrepancies are in the

breadth of the scutellum, the reticulation (or its entire

absence) of the elytra, and the denticulation of the scape

and of the prothorax.

I was at one time disposed to regard the species which

constitutes the type of this genus as only a peculiar form

of Xivuthrus, but the differences in the antenne, pro-

thorax, mandibles, &c., render it impossible to bring it in

that genus, as defined by M. Lacordaire.

In the more normal forms of this subfamily, the great

greater part belonging to Asia and Africa. There is only

one species in the collection.

668 Longicornia Malayana.

The female has shorter antenneze, shorter mandibles,

and much shorter fore-legs, the anterior angles of the

prothorax acutely produced, and the body manifestly

broader and more convex above. The legs are pretty

nearly equally denticulate in both sexes, although more

scabrous in the male.

Head blackish-brown, finely granulate; prothorax

chocolate-brown, closely punctured, opaque, but with

four nearly glabrous shining patches, the two largest:

central and triangular; scutellum oblong, rounded be-

hind, much broader in the female, coloured and punc-

tured as the prothorax; elytra brownish-fulvous, darker

at the base, shining, finely corrugate and very minutely

The antennz and legs are shorter, and the legs less

robust, in the female; and in R. Manille, the punctuation

on the abdomen is much less dense, and the deadness

of its surface therefore less pronounced, in that sex. Of

the following species, I only know the female. R. sutwr-

alis, the type, is unknown in our English collections.

Rhaphipodus Wallacit.

R. niger, nitidus; elytris pallidioribus, nitidissimis ;

prothorace utrinque basi leviter incurvato.

Hab.—Sarawak.

Black, shining, elytra with a brownish tint, and very

glossy ; head with a well-marked triangular excavation

between the eyes, the vertex finely granulate ; prothorax

short, very transverse, the posterior spine prolonged,

the portion of the side behind it very slightly incurved,

the disc with two large very glossy median callosities,

the rest finely and closely punctured, with the intervals

granuliform; scutellum oblong, slightly pointed behind,

finely punctured; elytra very convex, the punctures

minute, shallow, and much dispersed, except at the base,

where they are somewhat confluent, throwing the in-

' tervals into slight corrugations; body beneath dark

reddish-brown, minutely and very closely punctured ;

legs brownish-black, the outer and inner edges of all the

tibiee denticulate, but less so on the four posterior; an-

tenne brownish-black, the scape rather thickly punc-

tured, except at the apex, where it is nearly impunctate.

Length 17 lines.

This is a more convex species than I. Manille, with a

shorter and broader prothorax, the spine nearer the

base, the scutellum distinctly punctured, &c. The den-

ticulations on the four posterior tibiz are probably

hable to disappear, as they sometimes do in Ff. Manille.

Unfortunately the male is unknown, and the position

of the genus is therefore uncertain. It is remarkable for

its very small head and prothorax compared to the elytra,

and it is with reason that M. Lacordaire says, that its

appearance authorizes us to believe that the male will

prove this to be a very distinct genus.

Fulvous-brown, shining; head with small irregular

punctures, clypeus very concave, forming nearly the

whole space between the antennary tubers, mandibles

straight on the outer edge, sinuate internally at the base ;

prothorax very irregular above, roughly although not

largely punctured, the middle with two considerable ele-

vations, with a smaller one on each side, and at the base

two others of intermediate size and smoother, the lateral

spine depressed above, commencing behind the middle,

anterior to which the side is shghtly crenulate ; scutellum

oblong, rounded behind; elytra eight times as long as

the prothorax, and nearly twice as broad (exclusive of

the spines), finely punctured, the punctures more or less

confluent, the intervals forming little intricate rugosities ;

body beneath pale fulvous-ferruginous, glabrous, except

a slight pubescence on the sterna; legs and antenne of

the same colour, all glabrous and glossy.

Length 20 lines.

MALLOoDoNTINA.

M. Lacordaire, although not without hesitation, has

followed M. James Thomson in adopting this sub-family,

which has really nothing to distinguish it from the Rem-

phanine, except the absence of denticulations or other

asperities on their legs. Even as a specific character,

this requires to be received with caution; and it is even

admitted that ‘‘ some have this character normally, some

accidentally.” here are seven genera admitted, of

which only one, and that confined to a single species, is

in the collection.

Genus.

Archetypus, Thoms.

ARCHETYPUS.

“Archetypus, J. Thomson, Hssai &c., p. 319; Lacordaire,

Gen. vii. 150.

Caput magnum ; mandibulee validee, horizontales, elon-

gate, supra villose, intus pluridentatze. Oculi in-

tegri, valde distantes. Antenne corporis dimidio

vix longiores; scapo brevi, crasso; articulo tertio

haud scapo longiore; quarto et sequentibus sub-

zequalibus, ultimo longiore et acuto. Prothoraz

Elytra breviuscula, depressa, mutica. Pedes bre-

viusculi, validi, leves; tarsi mediocres, articulo

basali duobus sequentibus conjunctim breviore.

Prosternum productum, apice utrinque incisum. Me-

sosternum latum, excavatum. Corpus glabrum.

The female differs considerably from the above; the

head, particularly, is much smaller, the mandibles are

short, and the prothorax is broadest at the base. The

antennz are only slightly shorter, but the legs are con-

siderably less robust. M. Lacordaire mentions a second

species from New Guinea.

fiab.—Aru; Bouru; Waigiou; Dorey.

Reddish-brown, shining ; head darker, coarsely punc-

tured, the punctures crowded behind the eyes, scattered

in front; prothorax with a smooth callosity occupying

the whole disc, except at the sides, which are finely and

closely punctured; scutellum oblong, rounded at the

apex; elytra yellowish-testaceous, nearly smooth, but

covered with minute shallow punctures; body beneath

luteous-brown, the meso- and meta-sterna covered with

long grayish-yellow hairs; legs and antenne reddish-

brown.

Length 12-15 lines (¢) ; 22 lines (¢), including the

mandibles.

My typical specimen from Aru has the punctures on

the elytra much larger, and by their occasional confluence

forming marked irregular impressions, which do not exist

in the other examples now before me.

ZARACINE.

Two genera, each comprising a single species, are all

that at present constitute this subfamily. They are both

Malayan, although only one was detected by Mr. Wallace ;

the other, Neoprion, is stated to resemble a large-sized

Parandra.

Hab.—Sumatra.

Pitchy-brown, shining; head and prothorax darker,

finely and closely punctured; scutellum transversely

cordiform, pointed behind; elytra finely and very closely

punctured, the punctures mostly contiguous, each elytron

with four slightly raised coste, the outermost nearly

obsolete, but between this and the third a short and very

indistinct line posteriorly ; body beneath glabrous, pitchy,

shining, and minutely punctured; legs and antenna

dark brown, shining.

Length 11 lines.

CoLPoDERIN#E.

The third joint of the tarsi is either simple or divided

into very narrow lobes; in the latter case naked, or only

with stiff hairs beneath. This subfamily includes four

genera, exclusive of two whose position is doubtful. Two

of these are represented in the collection, another is

found at the Cape (Colpoderus) , and the fourth is a native

of Kangaroo Island (Notophysis) . ;

The length of the scape, and the form and direction of

the mandibles, essentially differentiate this genus from

the next (Hystatus) ; and it is the only genus of the

group which has the legs armed with small spines. The

tarsi are imperfectly tomentose beneath, the apices prin-

cipally of the three basal joints being clothed with short

hairs, leaving a naked space along the middle and base

of each.

like body at its base, the punctures and the spaces be-

from their number casting a shade which gives the whole

irregular, having six very feeble elevations placed trans-

versely; scutellum transverse, rounded behind, finely

granulate; elytra not broader than the prothorax at its

base, black, very glossy, more or less confluently punc-

The insect described below scarcely agrees with M.

J. Thomson’s H. javanus, nevertheless, I have thought

it best, without an examination of his type, to refer my

specimens to it. M. Lacordaire describes another species,

H. Thomsonii, apparently from the same localities. Mr.

Wallace found his specimens in rotten wood.

Blackish, or sometimes reddish-brown; head finely and

closely punctured; prothorax glossy in the middle, the

sides opaque and very roughly punctured; scutellum

transverse, rounded behind; elytra with an exceedingly

fine punctuation, the intervals having a delicate granu-

late appearance apparently when fresh, opaque, but at

the base and on the three raised lines of each elytron

somewhat glossy; body beneath more or less shining,

dark brown; legs and antennee dark brown.

Length 19-30 lines.

CLOSTERINA.

The large size of the eyes, approximate or contiguous

above, and their lower portion embracing the antennz

beneath, and feebly separated from the mandibles, seem to

be the differentiating characters which separate this sub-

family from the nearly-allied Orthostomatine. There are

only four genera, two with simple antenne, and two with

flabellate or pectinate antenne, but in the males only,

(Closterus and Polyoza). The only species found by Mr.

Wallace belongs to the former category.

Originally I considered this genus allied to Dorycera

through Osphryon, the remarkable grooving of the an-

tenne being present in both, and the habit not unlike;

the form of the epipleure of the metathorax, however,

places them in different categories of the family. I

believe my example to be a male, and a second, which I

noticed at Leyden, from its bulkier figure, so far as

I can recollect, is probably a female.

Dark brown, passing into reddish-brown beyond the

base of the elytra; head and prothorax opaque, finely

granulate, covered with a rather long delicate erect

yellowish pubescence, thicker at the sides, and forming

a dense fringe along the base as well as the apex of the

prothorax ; median groove confined to between the eyes,

the latter widely apart beneath; prothorax strongly in-

curved behind the lateral spine; scutellum rounded

behind, pubescent; elytra scarcely broader than the pro-

thorax, glabrous, except at the outer edges, which are

densely fringed with short yellow hairs, each elytron with

four narrow well-marked elevated lines, not continued to

the apex, and more or less connected posteriorly by finer

transverse lines, the intervals of the lines closely and

rather strongly punctured; body beneath glossy brown,

covered with long erect hairs on the breast, the abdomen

sparsely pubescent; legs fringed with fine hairs; antenne

glabrous, with the first three jomts dark brown, the

remainder clear ochre-yellow, the first and second joints

and the base of the third punctured.

Length 11 lines.

ANGOSOMATINE.

In all the previous groups of Prionide, the lateral

ridges, which separate the pronotum from the flanks of

the prothorax, have been strongly defined, but now the

character begins to disappear, the ridge on each side is

placed very low down, and in some cases becomes in part

obsolete or reduced to a fine line. Of the four genera

which compose this subfamily, a very good idea may be

formed from the common Afgosoma scabricorne of Hurope.

Cerambycide and Prienide ; and, according to M. Lacor-

daire’s system, will be broken up into smaller groups

co-ordinate or corresponding in rank with those of the

last two families.

Of the 291 genera and 1046 species, 132 genera and

734 species are here described for the first time.

Of the remaining 159 genera and 312 species which

had been previously characterized, 104 genera and 215

species were described in the recent publications of

Mr. Pascoe and Mr. James Thomson, principally from

the collections of Mr. Wallace.

In round numbers, then, Coleopterists are indebted

to Mr. Wallace’s labours for the knowledge of more

than 200 new genera and about 900 new species of

Malayan Longicorns.

Notes on the Localities given in Longicornia Malayana,

with an estimate of the comparative value of the

collections made at each of them. By Aurrep R.

WALLACE.

In order that students of this work may not be misled

by considering the materials on which it is founded to

be more complete than they really are, especially as

regards the geographical distribution of the species and

the comparative richness or poverty of the several islands,

I think it advisable to give a short sketch of each locality,

an account of my opportunities for obtaining Coleoptera,

and especially Longicorns, and an estimate of its pro-

bable richness compared with other districts in the

Archipelago of nearly equal extent. I take the localities

and islands in the order in which they are arranged in

the foregoing tables.

Penang. The small collection from Penang consists of

a few insects given me by Mr. Lamb on my way home,

and of a few more collected by a native sent there by a

friend. It gives no idea of the productions of the island,

which, however, are probably not very numerous, as a

large portion of it is more or less cultivated. The

opposite coast of the Province of Wellesley has produced

many fine and remarkable Longicorns, as may be seen

by Mr. Pascoe’s paper, published in the Proceedings of

the Zoological Society for 1866.

Malacca, Mount Ophir. I spent about two months

collecting in the interior of Malacca, ten days of which

were passed at Mount Ophir; but I found no very good

localities for insects, and accordingly devoted most of

my time to Ornithology. Many parts of the country are

covered with fine forests, and ought to be very produc-

tive if well worked under favourable conditions.

Singapore. My chief collecting ground was at Bukit-

tima, a Roman Catholic Mission Station in the centre of

the island. Here were several patches of forest on the

tops of low hills, and on one of these, about a square mile

in extent, I obtained nine-tenths of my Singapore col-

lections. A few statistics of these may be interesting.

The first day I went out, I captured eleven species of

Longicorns ; in a fortnight I had sixty species; in a

month near 100 species, (besides 140 Rhyncophora out of

692 Longicorna Malayana.

520 Coleoptera). I collected for about two months in

Singapore, a week of which was spent at Pulo Ubim, on

the northern side of the island, and a poor locality. That the

collecting ground was not nearly exhausted is proved by the

fact, that on going to the same spot again in 1856, I ob-

tained in eighteen days eighteen new species of Longi-

corns. My success was due to several favourable circum-

stances. The patch of forest I collected in was on tolerably

level ground, with a moist soil, the trees very lofty, with

tolerably thick undergrowth ; and it had been for some

years frequented by Chinese wood-cutters, who had made

numerous saw-pits, and had left the branches, and many

of the trunks, lying about in every stage of decay. Food

was thus furnished for a great variety of insects, and in

a little more than two months I was able to collect about |

700 species of Coleoptera (of which 135 were Longicorns)

in a very limited area.

Sumatra. I spent a little more than two months in

Sumatra, but it was the wet season, and I did not reach

the finest country for insects in the valleys of the central

range of mountains. My collections, therefore, give no

adequate idea of the entomology of this great island,

which I have every reason to believe is, at least, as pro-

ductive of insect life as any other in the Archipelago.

Java. I spent two months in the Hastern part of

Java (July to September, 1861), when it was excessively

hot and dry, and scarcely any insects were to be found,

and about six weeks in the Western part (September,

October), when it was so exceedingly wet and gloomy as

to be equally unfavourable for insect collecting. Under

these circumstances, my time was chiefly devoted to

birds, and the very few species of Longicorns I obtained

must not be held to indicate any poverty in this luxuriant

island, which, I believe, still offers a fine field to an

energetic collector.

Borneo. I spent nearly fifteen months in Sarawak,

but as I arrived at the beginning of the rainy season,

the first six were very unproductive in insects, as were

also the last four, which were spent in short voyages, or

at the town of Sarawak. Almost all my insect collections

were made at Simunjon, where some coal mines were

being opened, and about fifty Chinamen and Dyaks were

kept at work clearing forests, making roads, building

houses, &c. I reached this spot on the 14th of April,

Longicornia Malayana. 693

1855, and the next day commenced work. I rarely went

more than a mile from the house, and I may safely say

that nine-tenths of my insects were collected on a piece

of ground about half a mile square. The following state-

ment of the progress of my collections will show what a

wonderfully rich spot this was.

During almost the whole month of July, I was con-

fined to the house by a wound in my foot, and only

obtained a few specimens from the Chinamen, and from

my assistant, Mr. Allen, who was then very young and

inexperienced. Almost the whole of the thirty-four

species of Longicorns obtained before arriving at

Simunjon, were “found there also, so that I collected

about 270 Longicorns in six months on a square mile of

ground. A considerable number of these were single

specimens, and even when several specimens were ob-

tained, they were, in many cases, found only on one

spot and on one occasion. This gives a kind of acci-

dental character to a large part of the collection, and

renders it probable that this limited tract was not even

approximately exhausted. Until, therefore, other locali-

ties in Borneo are thoroughly worked under equally

favourable circumstances, it is impossible to form any

estimate of the total number of species of Longicorns

which may exist in that vast island.

Macassar. Although I spent nearly seven months in

Southern Celebes, I obtained few beetles, and especially

few Longicorns. This is owing to the country being so

very open and so much cultivated, and to the seasons

beimg so extreme; for seven months excessive drought,

and for five a deluge of water. The forests of the interior

would, however, no doubt produce many fine new

things.

694 Longicornia Malayana.

Menado, Tondano. Northern Celebes is much more

wooded and has a better climate than the South, yet

my nearly four months collecting there did not pro-

duce many Coleoptera. I am inclined to believe that

in all forms of life Celebes is really deficient in variety of

species, although it produces a number of very curious

and interesting forms.

Sula Islands. These were visited by Mr. Allen, who

devoted himself chiefly to birds. Being a small outlying

portion of the Celebes group of islands, these are probably

poor in species of insects.

Lombock. A volcanic island, with a very dry climate

and thorny vegetation. I spent two months there, but

finding it almost barren in insects, devoted myself chiefly

to bird collecting.

Flores. A volcanic island, but much larger and more

fertile than Lombock. Mr. Allen spent between two and

three months here, but obtained very few insects.

Timor. This large island is the poorest in the whole

Archipelago for insects, owing to the dryness of the cli-

mate and the almost entire absence of forest. I spent —

more than four months there, and the small number of

Longicorns obtained fully represents its comparative

productiveness.

Bouru. I was two months in this island, but it was the

wet season, and I was obliged to employ men to cut down

the forest or I should have got scarcely any Longicorns.

The country consists in a great part of open grassy hills

with a scattered vegetation, and is decidedly inferior

entomologically to Batchian.

Amboyna. My insect collections here were almost all

made during three weeks spent at a new plantation in

the middle of the island, in January 1858. Here were

several acres of newly cleared jungle, and by searching

daily among the stumps, trunks and branches, I obtained

nearly three hundred species of beetles, of which about

fifty were Longicorns.

Ceram. This large island seemed to me very deficient

in all forms of animal life. My collections were made at

many points on the south coast, and Mr. Allen collected

at Wahai on the north coast. 'To few places have I de-

voted more time and trouble, and the number of species

obtained must be held fully to represent its comparative

productiveness.

Longicornia Malayana. 695

Banda. A small island devoted to the cultivation of

the nutmeg, and not likely to be very productive in in-

sects. I visited it on three occasions, but spent only one

or two days there on each visit.

Goram, Manowolko. These small islands have scarcely

any forest vegetation, and are therefore necessarily poor

in insects. I collected for a week or two on the former,

and for a few days on the latter.

Matabello. Small coralline islands, with no forest. I

spent a week there in April 1860.

Ké. Islands chiefly of coralline limestone, covered with

a grand forest vegetation. I spent five days there in

January 1857, and tried to reach them again in 1860, but

failed. I believe they would well repay a thorough ex-

ploration by an entomologist.

Morty. Mr. Allen spent about two months on this

island, and obtained a rather better collection than on

Gilolo, owing to there being some natives engaged in

clearing forest.

Gilolo. Inever myself found a good collecting ground

on Gilolo, and did not spend more than a month there.

Mr. Allen collected for about a month in the northern

part, but did not obtain a great number of insects. I be-

heve it to be rather poor, owing to its volcanic soil, and

somewhat stunted forest vegetation.

Ternate. This small volcanic island cannot be very rich

in Longicorns, and I believe that the number I obtained

is a fair sample of its productions.

Makian. The species from this island were obtained

during a few hours’ visit.

Kaioa Islands. During five days here in October,

1858, I collected about one hundred species of Coleoptera,

and saw a greater quantity of large and showy species

together than I have ever seen elsewhere. The islands

are very small, and consist chiefly of raised coral rock.

It was the dry season, and a patch of forest had been cut

down a few days before, and every trunk and branch

swarmed with beetles. I obtained forty-four species of

Longicorns, some of which seem to have been overlooked

in the catalogue as occurring in this locality.

Batchian. I spent six months in Batchian, and worked

steadily all the time, yet I did not obtain as many species

as in Singapore in two months. I impute this to a real

deficiency of species in the Hastern compared with the

696 » Longicorma Malayana.

larger Western islands of the Archipelago. Batchian is

a most luxuriant and fertile island, with a varied soil,

and a fine moist climate, and I had very good collecting

grounds, so that I believe my collections fully represent

its entomological richness as compared with other parts

of the Archipelago.

Aru Islands. I spent six months here, but was only

for a short time in the best part of the islands, and was

there much hindered by a wounded foot, which confined

me to the house. Both here and at Dorey, therefore, I

believe that my collections do not give any adequate

idea of the richness of the district. :

Dorey. I spent three and a half months at Dorey, on

the North coast of New Guinea, and although much hin-

dered by illness and by bad weather, made a very good

collection of insects. The locality, however, was not a

good one, being almost entirely a raised coral reef

densely covered with forest, and with very few paths or

clearings; so that I am inclined to think that under more,

favourable conditions, New Guinea would rival Borneo

as a collecting ground, and far surpass it in the beauty

of its productions. I obtained here over a thousand

species of beetles, and one day captured ninety-five

species, the largest number I find recorded for a single

day’s work.

Saylee, Salwatty. These places at the North-west

extremity of New Guinea were visited by Mr. Allen, who

made a tolerable collection in the two months he spent

there, and I have every reason to believe that it is at

least as good a district as Dorey.

Mysol. The collections from Mysol were made by Mr.

Allen, who was there nearly six months altogether, but

did not find very good localities for Coleoptera. It is

probably not so rich as the main-land of New Guinea.

Waigiou. I was nearly three months at Waigiou, but

never found a good locality for insects. This is partly

owing to the natives livmg so much on sago, and

scarcely ever clearing the forest for cultivation. The

number of Longicorns I collected is much less than

would probably be obtamed under more favourable

circumstances. /

Gagie. I was only a few hours at this small volcanic

island, on my way from Waigiou to Ternate.
