The four specimens from which the above structural

diagnosis has been compiled, and which were taken by

Mr. G. Lewis in Japan, have much the primd facie

aspect (in their gibbose, roughened, setose, and scaly sur-

face, which is obscurely variegated, or in unrubbed ex-

amples spotted, with cinereous scales) of a small Yar-

phius ; nevertheless a careful inspection will shew that

they recede altogether, in reality, from the members of

that genus. Thus, their antenn, instead of being 11-,

are only 10-jointed, with the club globular and solid, in-

stead of biarticulate-—the eleventh joint being so com-

pletely dost, or soldered to the penultimate one, as to form,

along with it, a perfectly undivided mass. Their eyes,

too, are prominent and setose; and their prothorax is not

new genus of Colydiide, from Japan. 3

scooped-out, on either side, beneath, for the reception of

the antenne when thrown backward in a state of repose.

In the fact of their eyes being studded with short bristles

they agree with Trachypholis (= Tarphiodes, Woll.),

from the Malay peninsula and the islands of the Oriental

archipelago; but in that group, as well as in Tarphio-

soma (from southern India and Ceylon), the antennz are

11-jomted, and indeed nearly similar to those of Tar-

phius.* On the whole, they are perhaps (judging simply

from the published description) more nearly allied, at any

rate as regards the construction of their antennz, to the

South American Paryphus,—though even there the pro-

thorax is stated to have grooves beneath it for the recep-

tion of the antennz, and the terminal joint of the maxil-

lary palpi is said to be securiform. I have little doubt

therefore that Mr. Lewis’s Japanese insect constitutes the

type of a well-marked and totally new genus,—belonging,

I may add, to that particular section of the Colydiide in

which the first three joints of the feet are subequal, the

tibie filiform and unarmed at their apex, and the whole of

the legs widely separated at their base. In the details of

its oral organs Pseudotarphius is almost coincident with

Tarphius, Tarphiosoma and Trachypholis; but I have

had no opportunity of comparing them with those of

Paryphus.

* Although I have not been able to inspect a type, I think it is most

probable that Motsechoulsky’s genus Zarphisoma (Bull. Mose. ii. 504),

which was established in 1863 to receive two species from Ceylon and

Timor, is identical with my Zarphiosoma, enunciated during the preceding

year for the reception of an insect from Coimbatoor in southern India.

Be this however as it may, I possess a Zarphiosoma (given to me some

time ago by the late Dr. Schaum) from Ceylon, which is unquestionably

distinct from the Malabar 7. indiewm (to contain which I originally pro-

posed the group); and this species, which is remarkable for its unicolorous,

blackish-brown surface, and the excessively long and erect setz with which

it is sparingly studded, I will take the opportunity of thus briefly charac-

terizing :-—

rem nomen triviale stabilivi.

The general outline of this Tarphius-, or Coxelus-,

like little insect is very peculiar,—its prothorax and

elytra being both of them exceedingly convex, and sepa-

rately rounded, which causes it to seem much divided in

the middle (or rather at the junction of the two); whilst

its roughened and setose surface is more or less obscurely

clouded, or even (in unrubbed specimens) maculated, with

dirty-white scales. The blotches, or spots, into which

these paler scales tend (on the elytra) to condense them-

selves are in much the same positions as the nodules and

patches are (when developed) on the Tarphii,—a rather

large and longitudinal one being on either side of the

scutellum, and about four smaller ones on each elytron,

the one behind the middle disk having a tendency to form

with the corresponding one on the opposite elytron a kind

of extremely ill-defined postmedial fascia, which however

is manifestly only traceable when the specimens are highly-

coloured and fresh.

It gives me great pleasure to name the species after its

discoverer,—whose entomological researches in Japan have

brought to light so many novel, and geographically in-

teresting, forms.

II. On the Cossonide of Japan.

By T. Vernon Wo .uasron, M.A., F.L.S.

{Read 6th January, 1873. |

HAvInG been requested by Mr. G. Lewis to draw up a

paper on the various members of the Cossonide which he

obtained during his late residence in Japan, and which

form an important (though perhaps not very considerable)

item of his Coleopterous gleanings, I have done so,—though

not without some slight degree of regret at the large num-

ber of new genera which I have found it necessary to esta-

blish. I say “regret,” because where species are compa-

ratively small in size, and present no modifications of

structure which are at once striking and conspicuous, and

where moreover external characters can alone be employed

for the purposes of classification, one would far rather

admit them into groups which are already recognized than

propose additional ones for their reception. Yet, after a

very careful examination of Mr. Lewis’s material, I feel

convinced that the ordinary European types do not prevail

in that particular portion of the Japanese empire to which

his researches have been confined,—their places being

manifestly taken by kindred, and to some extent repre-

sentative, forms, which have geographically too much

importance not to be acknowledged as distinct. What

the case may be in the northern and central parts of the

archipelago I have no means of ascertaining,—for, unless

Iam much mistaken, Mr. Lewis’s explorations were pro-

secuted chiefly in the island of Kushiu and the southern

division of Nipon; but it is not improbable that the large

island of Yesso, and the still larger and more northern one

of Saghalien (which nevertheless is not, I believe, regarded

as an integral portion of the Japanese empire), would have,

to a considerable extent, faunas of their own. Be this

however as it may, I would desire to state that it is to the

south of Japan that the present memoir must be considered

as more properly to pertain.

. Glancing at the 18 species described below (and which

are embodied in 15 genera), there are a few points which

strike one as requiring comment,—amongst which stands

TRANS. ENT. SOC. 1873.—PART I. (MAR.)

6 Mr. T. Vernon Wollaston on the

pre-eminent the remarkable fact that they appear to be all

of them undescribed,* and that most probably, therefore,

if they are not absolutely endemic, their areas of distribu-

_tion are exceedingly limited in extent. This however is

nothing more than what my own experiences in the Ma-

deiran, Canarian, and Cape Verde archipelagos would

have led me to anticipate, for in each of those groups their

respective Cossonide are almost wholly peculiar; and the

same is equally the case at St. Helena, and will perhaps

be found to be so in most remotely-situated islands and

archipelagos. But what surprises me more is that there

does not appear to be any particular type ( judging at least

from the material to which I have had access) which, like

Microzxylobius at St. Helena and Caulotrupis in Madeira,

would seem as it were to reign supreme, and to be par

excellence prolific in its modifications; for, on the contrary,

by far the greater number of the species which I have exa-

mined appear to belong to genera which are unmistakeably

different from each other. Still, much allowance must

doubtless be made for the limited size of the region which

Mr. Lewis had the opportunity of investigating; and

I would conjecture, therefore, that if any very numerous

additions to the Cossonideous fauna of Japan are ultimately

made they will probably pertain for the most part to the

genera Phleophagosoma, Pseudocossonus, and Heterar-

thrus, each of which have two representatives here enume-

rated, and the last of which appears to occur likewise in

Ceylon.

One of the most salient facts is the discovery by

Mr. Lewis of a new Pentarthrum, and also of two very

distinct and well-marked genera (Pentacoptus and Ty-

chiodes) in the small subfamily of which Pentarthrum is

now recognized as the type, and in which the funiculus is

composed of only five articulations. One of these genera,

however, namely, Z'ychiodes, although communicated by

Mr. Lewis, was in reality detected, I believe, by Dr. A.

Adams,—who found several examples of it in the island

of Awasima, near Sado, on the north-west coast of Nipon,

* The only one which I feel might possibly prove to be an exception to

this statement is the first species on the list,——the Zetratemnus sculptu-

vatus,—which seems to have a rather wider geographical range, and which

may perhaps have been characterized as a Dryophthorus. Still I cannot

satisfy myself that it will quadrate with the diagnosis of any described

species; though it is certain that several closely allied forms have been

published (I believe erroneously) as Dryophthori. .

Cossonide of Japan. 7

and consequently at a rather higher latitude than the area

which was explored by Mr. Lewis. The Pentarthrum

itself is peculiarly interesting, since the only two exponents

of its group which had hitherto been brought to light are

(respectively) from England and the island of Ascension ;

and I have remarked, in the proper place, on the affinity

which it possesses, both in structure and habits, with those

two species.

Amongst the Cossonides proper, Pholidoforus is un-

usually aberrant on account of the robust scales (so familiar,

and ordinary, in certain other departments of the Rhyncho-

phora) with which it is clothed; and Xenomimetes is note-

worthy from representing, as it seems to me, in Japan, the

genus Hremotes (or Syntomocerus) which infests the pine

trees of the Canarian archipelago. Spherocorynes intro-

duces us to another swb-Hylastideous form ( yet neverthe-

less strictly Curculionideous), of a very marked character ;

whilst Stenoscelis, which is still nearer to the Hylastide

(being indeed the nearest to that family of all known

Rhynchophorous types), has an interest, from a geo-

graphical point of view, emphatically its own, on account

of the single exponent as yet described (the S. hylastoides,

Woll., Journ. of Ent. i. 142, t. 11, f. 1) beg a native of

St. Helena and the Cape of Good Hope. Indeed Steno-

scelis, Pentarthrum and Hexarthrum are the only genera,

out of the 15 enumerated in this paper, which do zot

appear to be absolutely new.

In order to make the various forms, and their classifica-

tion, intelligible, I have compiled, as a slight aid to the

eye, the following tabular synopsis :—

cipue tarsis) brevioribus, necnon coxis anticis inter se

10 Mr. T. Vernon Wollaston on the

Dryophthoro aliter discedit elytris angustioribus, magis

parallelis, lateraliter compressis, utrinque ad apicem multo

magis cariniformibus, uncoque tibiali minus elongato.

A terga, quatuor, et téuvw, scindo.

There can be no doubt that the weevil from which the

above characters have been drawn out, if not already de-

scribed as a Dryophthorus, is congeneric with several

which have been referred to that group. Yet a careful

comparison of it with the European D. lymexylon (which

is stated expressly to be the type, and for examples of

which, from Finland, I am indebted to Mr. E. W. Jan-

son) is abundantly sufficient to shew that it cannot in

reality be admitted into the same actual genus with that

insect,—its shorter rostrum and legs, and (above all) the

fact of its anterior coxz being comparatively wide apart

from each other (instead of nearly contiguous), whilst the

posterior pair, on the other hand, are not so distantly

separated as is the case in Dryophthorus proper, being

differences of the utmost importance in this particular

department of the Rhynchophora. As regards its less

essential details, 1 may observe that its elytra are nar-

rower and more parallel (or laterally-compressed) than in

Dryophthorus, and have their keeled apical margin very

much more prominent and developed; and that its an-

tenn are implanted a little further behind the middle of

the rostrum, whilst its tibial hook and feet are consider-

ably more abbreviated.

In other respects (and which it retains in common with

Dryophthorus), I will merely mention that its 4-jomted

funiculus and transverse eyes, and the fact of its abbre-

viated feet being distinctly pentamerous (the fourth articu-

lation, although smaller than the preceding ones, being

quite conspicuous and exposed—an almost unique feature,

if not indeed entirely so, in the Rhynchophora), will com-

bine to separate it from every other Cossonideous form

with which we are here concerned.*

* In its shorter rostrum, antenna, legs, and feet, as well as in the pro-

portions of its funiculus-joints, Zetratemnus would appear (judging at

least from the published diagnosis) to agree better with the genus Cha-

rorhinus, Fairm., from the south of Europe, than with Dryophthorus ;

but from that group its eyes and tarsi will (apart from all other differences)

at once separate it,—the former being transverse and depressed, instead of

rounded and prominent, whilst the latter are filiform and conspicuously

5-articulate; whereas the feet in Chewrorhinus are said to be (vide Fair-

maire, in the French Annales for 1857, p. 742, and also Lacordaire, Gen.

vii. 323) on the ordinary pseudotetramerous type, with their third joint

Cossonide of Japan. 1

Its dark hue, in conjunction with its opake and very

deeply and coarsely sculptured surface, which is more or

less sparingly besmeared with a kind of mud-like scaly

deposit, and which tends to fill up the various inequalities

and punctures, will serve additionally to distinguish the

present insect; though it is true that these particular

characters exist likewise, to an almost equal extent, both

in Pentacoptus and Coprodema. Nevertheless the strue-

tural details which I have given above (par excellence of

funiculus, eyes, elytra, and feet) will suffice at once to

separate the 7. sculpturatus from the members of those

two genera.

Judging from the comparatively large number of indi-

viduals now before me, and which Mr. Lewis would ap-

pear to have taken principally at Hiogo, in the island of

Nipon, (“in old fungus-covered pines bordering a water-

course”), I think it is very likely that the present Tetra-

temnus is (if not common) at least widely spread ; for it is

remarkable that I had already an example of it in my

collection which I captured a few years ago (dead) out of

a cup of tea, while in the island of Jersey,—a fact which

would perhaps indicate that the species occurs equally in

China, and that the example alluded to was accidentally

imported (much after the fashion which we are accustomed

dilated and bilobed. By-the-by, it is much to be regretted that the gene-

rality of the continental Coleopterists still persist in characterising the

tarsi of the Rhynchophora as tetramerous (which it is perfectly well

known that they are not), and that too while the more correct term “ pseu-

dotetramerous” (proposed by Westwood upwards of thirty years ago,—

vide Introd. p. 44) so exactly expresses their real structure.

At first sight the opake and coarsely sculptured little

weevil for the reception of which the above genus is pro-

posed has much the outline and aspect of a small Gro-

nops ; though of course, when closely inspected, every one

of its characters (more especially as regards its rostrum,

antennee, and tibial hooks, and the soldered first and second

segments of its abdomen) will instantly remove it from

Pentarthrides of the Cossonide ; whilst its fully developed

eyes, and medially inserted antennz, in conjunction with

its Just appreciable scutellum and elongate metasternum,

will tend still further to retain it in the immediate vicinity

of Pentarthrum proper.

Apart from the features (some of them generic ones)

above alluded to, the excessive shortness of the limbs of

this coarsely sculptured and somewhat Gronops-shaped

little Cossonid, added to the fact that its elongate-squarish

prothorax (which is deeply constricted just behind the

front margin) is appreciably narrower than the elytra,

whilst its longitudinally strigulose rostrum is short and

broad, but nevertheless linear and comparatively depressed,

will all combine to give it a character which, when once

seen, it is impossible to mistake. It appears to have been

taken by Mr. Lewis at Nagasaki, in the island of Kushiu,

—“out of an old Camellia tree im the garden of the

British Consulate.”

Although Pentarthrum is not a new genus (it having

been established by myself in 1854), I have nevertheless

given a full diagnosis of it in order to point out the exact

particulars in which it differs from the other groups of the

Cossonide with which we are here concerned ; and it will

perhaps be sufficient therefore to remark that the compa-

ratively narrow, parallel, and elongate bodies of the few

species which have as yet been ascertained to compose it,

in conjunction with their but very slightly shining, piceous

and rather closely sculptured surfaces (which are entirely

free from both scales and pubescence), their almost medially

inserted antennz, their 5-jointed funiculi, and their linear

but somewhat robust rostra, will suffice to distinguish it

from its immediate allies.

Cossonide of Japan. 15

The structural characters of this narrow and linear little

Cossonid shew it to be a true Pentarthrum,—its 5-jointed

funiculus, medially-inserted antenne, and its developed

eyes and scutellum, added to its colour, outline, and sculp-

ture, being in entire accordance with the two hitherto de-

scribed members of that group. I say “two,” because a

more careful examination of the unique weevil from St.

Helena, which I enunciated nearly three years ago under

the title of Pentarthrum subcecum,* has recently con-

vinced me that it is the type of a new genus allied

to Mesoxenus (well characterized not only by its ob-

solete eyes and scutellum and its more apically-im-

planted antennz, but likewise by its convex, largely-

developed prothorax and general aspect and sculpture),

and not an “aberrant Pentarthrum.” So that, up to the

present date, only two veritable Pentarthra had been

brought to light,—namely, the English P. Huttoni (for

the reception of which, in 1854, I originally proposed the

genus), and the P. cylindricum, which was detected by

the late Mr. Bewicke in the island of Ascension: and

I need scarcely add therefore that a third representative,

from Japan, and one so remarkably well defined, is a fact

of considerable importance geographically. As elsewhere

stated, however, there is a peculiarity about the modus

vivendi of the Pentarthra which renders it highly probable

that the group will be found eventually to have a very wide

range,—their habits being, apparently, to follow im the

wake of civilization by attaching themselves to old planks,

boards, rafters, casks, &c., on the rotten (and often tinder-

like) wood of which they more especially subsist. Thus

the English P. Huttoni was obtained originally amongst

logs of wood which had been long laid up in an out-house,

and it was subsequently met with in a decayed cask near

Plymouth, and by myself in portions of an ancient plank

adjoining my house and conservatory at Teignmouth ; and,

in like manner, the P. cylindricum, at Ascension, was

captured abundantly by Mr. Bewicke in the broken-up

wood of a worn-out box in which plants had been culti-

vated. It is consequently quite in accordance with what

I may perhaps be permitted to call their generic mode of

life that the present Pentarthrum should have been dis-

covered by Mr. Lewis, in Japan, “ by beating the straw

roofing of old cottages near Nagasaki;” and I may further

remark that I believe him to be perfectly correct when he

* Vide Ann, Nat. Hist. (1869).

16 Mr. T. Vernon Wollaston on the

conjectures that “in all probability it really lived in the

rafters.”

The P. angustissimum is more nearly allied to the

P. cylindricum from Ascension than to the English P.

Huttoni, but it is relatively very much narrower than

either, its rostrum is a little longer, and its prothorax is

more constricted behind the front margin, and more de-

pressed (as in Mesites) down its posterior disc. Its elytra

also are more closely sculptured, and have their interstices

more raised. In its short antenne and small club it is

more in accordance with the Ascension species than with

the English one.

The very anomalous little Cossonid (several examples

of which were taken by Dr. Adams in the island of Awa-

sima, near Sado, off the north-west coast of Nipon) from

which I have compiled the above generic diagnosis is one

of the most remarkable members of the family which has

hitherto been brought to light, and one which is especially

important as adding another and most well-defined form

to that particular section which is characterized by Pen-

tarthrum, Pentacoptus, the Atlantic Pentatemnus and

Mesoxenus, the south-European Amaurorhinus (if indeed

it be truly distinct from Mesoxenus), and the St. Helena

Microxylobius,—in all of which the funiculus is composed

of only five joints. Primd facie indeed its aspect is so

remarkable (from its rather depressed, wide, oblong-elliptic

body, short, transverse prothorax, and extremely slender,

linear rostrum) as to be slightly suggestive of a large

Tychius and other members of the Hrirhinide ; never-

theless the structure of its abdomen, tibiz, and other

details, show it to be an unmistakeable Cossonid. In

other respects it is conspicuous for the smallness of its

head, and for its antenne (which are rather long and

slender) being implanted a trifle behind the middle of its

very narrow rostrum, with their scape flexuose, and their

funiculus-articulations (the second of which is compara-

tively elongate and subconical) somewhat loosely connected

together. Its metasternum and the basal segment of its

abdomen are both of them rather shorter than is the case

in the ordinary members of this family (though the former

is not so abbreviated as in the Microzylobii of St. Helena) ;

its scutellum is very apparent; its legs are a good deal

thickened, especially the anterior pair; and its feet are

considerably developed, with their third joint widened and

deeply bilobed.

In its densely scaly surface the present insect affords a

curious exception to what is usual amongst the Cossonide;

for although it is true that Tetratemnus, Pentacoptus,

Coprodema and Exodema are likewise remarkable for the

few mud-like scales with which they would seem to be

. more or less partially incrusted, in Pholidoforus the body

is regularly and somewhat closely beset with short, thick,

fulvo-cinereous scaliform sete,—a portion of which are

slightly erected, and the others altogether decumbent. Yet

the structure of its abdomen, tibiz, eyes, rostrum, and

7-jointed funiculus show it to be an unmistakeable member

of this subfamily. In other respects it may be known by

its narrowish and fusiform outline (it being parallel in the

middle, but acute both before and behind), by its rather

long and slender antennz being inserted just before the

middle of its appreciably curved rostrum, by its eyes being

small and rounded but very prominent, by its funiculus

having the second joint scarcely at all longer than the

third, and by its feet being a good deal developed and

lengthened,—their third articulation being rather broad

(for the Cossonide) and bilobed.

Not to mention the many features to which I have above

species described in this paper by the dirty, yellowish-

brown hue of the short sete and mud-like scales with which

its opake and coarsely-sculptured surface is rather densely

The primdé facie aspect and outline of the opake and

deeply sculptured little weevil for which I have been com-

pelled to establish the present genus is a good deal sugges-

tive of Calandra; but its 7-jointed funiculus, medially-

inserted antennz, widely separated eyes, and short, filiform

feet, apart from the other details of its structure, show it

to be an undoubted Cossonid. Indeed, in the tendency

of its surface to become unequally incrusted with mud-lke

scales (or which, perhaps, has more the appearance of a

kind of scaly deposit) it approaches Pholidoforus ; but in

that genus the clothing is not only very much denser and

more regular, but the scales are of an ordinary character,

many of them being suberect (though short) and setiform.

In other respects Coprodema differs from Pholidoforus in

being rather smaller, and less acute both before and behind,

and more coarsely and conspicuously sculptured, in having

its elytra appreciably truncated at their hinder apex (though

perhaps not sufficiently so to expose any decided portion

of the pygidium), and in its limbs being very considerably

shorter,—the antennz, moreover, being implanted in the

middle of the rostrum (instead of somewhat before it),

whilst its tibial hook is more largely developed and its

feet very much less so (the third jomt being small and

almost simple, and the terminal one comparatively abbre-

viated and but little clavate, with the claws smaller).

I have already so fully pointed out the structural

peculiarities of this insect that I need scarcely do more

than call attention to its very coarsely sculptured surface,

the elytral interstices being likewise raised into conspi-

cuous ridges or coste. There are thirteen examples of

In its general outline, and opake, densely sculptured

ters have been taken so closely resembles Coprodema that

it might well be regarded, at first sight, as another mem-

ber of that group; yet when accurately inspected it differs

so essentially in the structure of its feet, which are not

only much longer but have their third joint (instead of

small and simple) appreciably widened and bilobed, that I

cannot but treat it as the type of a nearly-allied but pro-

bably distinct genus. As regards its less important par-

ticulars, its antennz are a trifle more elongate, and not

quite so medially inserted, being implanted just percep-

tibly before the middle of its (rather thicker) rostrum, its

eyes are a little more developed, its elytra are not at all

Apart from the characters above enumerated, the pre-

(which prima facie it very closely resembles) in being a

trifle larger and more parallel, and in its elytral inter-

stices being less sharply costate and more transversely-

rugulose. The single example from which the diagnosis

has been compiled is also a little more piceous in hue, and

not quite so densely besmeared with mud-like scales; but

this may be merely accidental. It was mixed-up with

Mr. Lewis’s specimens of the Coprodema calandreformis

A Phleophagus, et cdp«, corpus.

(Typus.—P. minutum.)

The two insects from which the above structural diagno-

sis has been compiled are so dissimilar in size, and are

so distinct in several points of their structure (albeit not

very important ones), that I cannot feel entirely satisfied

that they should be looked upon as members of the same

actual group; yet, being unwilling to multiply genera

unnecessarily, and thinking it far from improbable that

species of intermediate stature will ultimately be brought

to light, I prefer to treat them as congeneric,—premising

only that I would desire to regard the P. minutum as the

type.

at their prima facie aspect these two insects have more

perhaps in common with the European Phleophagi and

Rhyncoli than any other of the species which were ob-

tained by Mr. Lewis in Japan; and yet from both of

those (nearly allied, and not very satisfactorily separated)

forms they are, I think, manifestly distinct,—differmg in

being not only narrower and more fusiform and less con-

vex, but likewise in their prothorax and rostrum being

proportionately more elongate, whilst their tarsi are ap-

preciably shorter, the first joint being (instead of produced)

subequal in length with the second and third.

Although, however, the antennz of both of the species

described below are inserted medially, there is a slight

disparity in the structure of those organs, as well as in

that of their tibie,—the second funiculus-joint being no

longer than the following ones in the P. minutum, “and

Cossonide of Japan. 25

the tibize being armed at their inner apex with an evident

minute spinule; whilst in the P. cuvirostre the tibize have

their inner angle almost simple, and the second articula-

tion of the funiculus appreciably a little elongated and

obconic. Moreover in the first of the species the body is

very minute and fusiform, whereas that of the second is

comparatively large, and more depressed and _ parallel.

Yet these discrepancies are very likely, after all, no more

than specific ones.

Apart from its characters of comparatively minute size,

narrow, fusiform outline, rather elongate rostrum, and

deeply sculptured, convex upper surface, the present in-

teresting little Cossonid may be further known by its

piceous hue and brightly rufescent limbs, as well as by

its (elongate-ovate) prothorax being almost unconstricted

behind the apex, and by its eyes being hardly at all promi-

nent. It is the smallest member of the family which was

brought by Mr. Lewis from, Japan. Six examples of it

are now before me, which Mr. Lewis states were captured

by a native collector, at the roots of a wild grass, on the

sandy coast of Simabara, in the island of Kushiu.

Captum ad Hiogo, in ins. Nipon, hactenus unicum.

As already implied, I do not feel absolutely certain that

this insect 1s congeneric with the preceding one; yet,

judging from the single example from which the diagnosis

has been drawn out, I scarcely think that its points of

discrepancy are of sufficient importance to indicate generic

separation,—for in their antenne being inserted medially,

as well as in their rostra being comparatively long and

slender, their scutella conspicuous, and their feet short

and subfiliform (the first jomt of which is no¢ elongated),

they are inter se on much the same type. Yet the present

species is prima facie exceedingly different from the

P. minutum,—being not only very much larger, darker,

less narrowed, more parallel, more deeply sculptured and

more depressed, but likewise with its scutellum larger,

and its antenne more robust, the second funiculus-joint of

which is (although short) appreciably longer and more

obconical than those which follow it. Its elytra also, in-

stead of being elongate-ovate (or a little widened behind

the middle), are more decidedly parallel, or, if anything,

perhaps a trifle narrowed (gradually) behind; and its

tibize do not appear to be armed with a little spinule at

their inner apex. In addition to which its rostrum is

somewhat thicker (especially towards the base), as well as

convexer and more arcuate; and its eyes are less de-

pressed.

from which the above description has been drawn out

appears to have been captured by Mr. Lewis at Hiogo, in

the island of Nipon.

The present genus, the two representatives of which,

28 Mr. T. Vernon Wollaston on the

described below, have much the primd facie appearance

of small Cossoni, is well characterized by its extremely

robust legs and abnormally short and incrassated feet, the

apical joint of which is unusually abbreviated and (instead

of being clavate) conical.* Its claws are excessively

minute; and its antennz, which are a good deal thickened,

are implanted immediately behind the middle of the ros-

trum. In other respects it is remarkable for its broad

funiculus-joints, which are closely compacted together (the

second, moreover, not being at all longer than those which

follow it), and for its rather small and but very slightly

_ widened capitulum, as well as for its greatly developed

prothorax, distinct scutellum, elongate, parallel outline,

and the comparative robustness of the hook and spine at

apex of its tibize,—the front pair of which, moreover, are

densely fulvo-pubescent towards their inner extremity.

Both of the Pseudocossoni here described agree in their

the fact of their head and prothorax being more finely and

sparingly punctulated than in any of the other members of

the family with which we are concerned; but the present

possible that the conical structure of the last joint of the feet may prove to

be a sexual character; but until further material, of the two species now

species is considerably larger, and a trifle less depressed,

than the P. brachypus, and its rostrum and antennx are

longer. The former is likewise a little narrower (rela-

tively) and more arcuate, its prothorax is more rounded-

outwards in the middle, its elytra are unmargined at their

extreme base, and the hook and spine at the apex of its

tibiz are somewhat more powerfully developed. The

unique example from which the diagnosis has been com-

piled appears to have been captured by Mr. Lewis near

As already implied, the present Pseudocossonus is a

little smaller and more depressed than the preceding one,

and its rostrum and antenne are shorter. The former,

too, would seem to be a trifle broader, relatively, and less

convex.

The prothorax, moreover, of the P. brachypus is more

triangular (its widest point being behind, instead of at the

middle): its elytra are distinctly margined at their extreme

base (particularly on either side of the scutellum), with

their humeral angles appreciably subrufescent; and the

spinule at the inner apex of its tibize is not quite so power-

fully developed. Like the P. brevitarsis it is unique, the

single example having been taken by Mr. Lewis, at

Tomatzu, near Nagasaki, in the island of Kushiu.

The narrowish, elongate-fusiform outline, and the rather

short and thick (though parallel, and apically truncated)

rostrum of the insects which compose the present genus,

added to their slenderer and less abbreviated legs and

their comparatively lengthened feet (the terminal articula-

tion of which differs in shape, apparently, according to

the sex), will serve to distinguish it from the allied groups.

Indeed, the sexual peculiarity of the apical tarsal joint is

very curious, and one which I do not remember to have

observed in any other Rhynchophorous form,—it being

ordinary and clavate in the males, but conical (or, rather,

fusiform-conical) in the females, the widest part being

towards the base instead of towards the apex.* And

Heterarthrus is further remarkable for the punctation of

its head and prothorax being dense but at the same time

fine, and for its elytra being more or less of a pallid hue

(sometimes ornamented with a black patch),—an arrange-

ment of colour which gives the insects a totally different

aspect from any of the other Cossonide with which we

have heretodo. Asregards the antenne, they are inserted

either in the middle or just before the middle of the ros-

trum; and the four posterior tibiz are subflexuose and

slender (particularly at their base), and less evidently

armed at their inner apex. Their second funiculus-joint

is (like the succeeding ones) short, and their club is large

and abrupt.

* This character, although real, is not a very easy one to observe,—

inasmuch as when viewed laterally the joint seems to be equally clavate,

and similar, in both sexes; and it is only when inspected carefully from

above, and beneath a high magnifying power, that the conical outline, in

that of the females, becomes evident. And I may add that, since writing

the above, I haye remarked the same peculiarity of tarsal articulation in

a Cossonid from Ceylon, which has been communicated to me by Mr.

Janson, and which indeed I have every reason to suspect (without further

examination) is a true Heterarthrus.

32 Mr. T. Vernon Wollaston on the

Being precisely similar in colour and sculpture, I should

certainly have regarded this Heterarthrus as the other sex

of the following one had not the more numerous examples

of the latter revealed the fact that both males and females

(as proved by the construction of their tarsi) are un-

doubtedly present. Hence I have no choice but to treat

the two female individuals from which the above diagnosis

has been drawn out as specifically distinct from the

Hi. pallidipennis. Regarding this conclusion, therefore,

as almost unavoidable, I may add that the H. Lewiszz is

not only larger than its ally, and with appreciably longer

legs and antennz, but that its rostrum likewise is a little

more lengthened (with the antennz implanted just before,

instead of at, the middle point), and its third tarsal joint

is just perceptibly more expanded and bilobed. It was

taken by Mr. Lewis near Nagasaki, in the island of

Kushiu, by beating old hedges.

I have already implied that the present Heterarthrus

is so like the preceding one that I should have taken it

for a mere sexual form of the latter, had I not found a

structural difference in the tarsi of the few examples now

before me, which would seem to imply that both males

and females are undoubtedly indicated; and I am there-

fore constrained to look upon the H. pallidipennis as

specifically distinct from the H. Lewisii. The former

may consequently be defined as being merely a little

smaller than its ally, and in having its legs, rostrum, and

antennz appreciably shorter,—the latter, moreover, being

implanted more strictly medially than ante-medially.

Mr. Lewis appears to have captured his specimens, along

with those of the last species, out of old hedges, near

Nagasaki, in the island of Kushiu.

like that of the typical Rhyncoli, nor comparatively slender

and linear as in the normal members of Phleophagus, but

somewhat intermediate between the two,—being short

and incrassated, but nevertheless conspicuously parallel

throughout (though not quite so short and broad, nor so

depressed, as in Xenomimetes). Its scrobs, too, is very

differently constructed from that of Rhyncolus,—being

short, deep, wide, and auriculiform at its base, and then

suddenly narrowed and bent downwards, at a sharp angle,

beneath the eye. In addition to this, its eyes are larger

and more prominent than those of the Rhyncoli (and the

Phleophag?), its antennz are implanted behind (instead

of before) the middle of the rostrum, and its tibie are

roduced at their inner angle into a more distinct spinule.

The facies and sculpture of the remarkable Cossonid

from which the above structural diagnosis has been com-

piled have so much in common, at first sight, with certain

sub-Curculionideous forms (like Hylastes) of the Scoly-

tide, that it must clearly be regarded as the type of

another group in the vicinity of Lremotes (or Syntomo-

cerus), which infests the pine trees at a high elevation

in the Canarian archipelago. Yet its rostrum, although

short and broad, is neither so short nor so broad as in that

genus, and, moreover (instead of being thick and trian-

gular), it is parallel and depressed, and appreciably nar-

rower than the head. Its antennz, also, are very different

from what obtains in that group, being less thickened ;

. and there is not that peculiarity, which forms so marked

36 Mr. T. Vernon Wollaston on the

a feature in Eremotes, as regards the diminished (and

almost concealed) second funiculus-joint. Its elytra,

moreover, are curiously rounded off separately, and sub-

divaricate, at their apex,—much after the fashion we see

in various Apions of the vernale type. Yet, in spite of

these discrepancies (especially as concerns the breadth

and outline of its rostrum), I feel satisfied that its real

affinities are more with the particular genus to which I

have just called attentiou, than with the Rhyncoli ; though

since it cannot be admitted into the section of the family,

characterized by Eremotes and Stenoscelis, in which the

rostrum is excessively abbreviated, thick, and triangular,

I have placed it thus far towards the close of the present

division.

The deep-black, cylindric, and coarsely, densely sculp-

tured body of this insect, added to its short and broad,

yet parallel, rostrum, and its very prominent eyes, will, in

conjunction with the various characters to which I have

above alluded, abundantly distinguish it from every other

member of the Cossonide with which we are here con-

cerned. It was captured in considerable abundance by

Mr. Lewis, on various occasions, amongst old pine trees

near Nagasaki, in the island of Kushiu.

The genus Hezxarthrum (which, in the size and facies

of its exponents, has much the primd facie aspect of

Rhyncolus) is at once remarkable amongst the Cossonides

for its 6-articulated funiculus, its extremely abbreviated

antenne, and its rather shortly-cylindric outline,—the

elytra (which are very minutely and remotely asperated,

when viewed beneath a high magnifying power) being

obtusely rounded behind. It is also further distinguished

by its shortened rostrum and legs, by its first funiculus-

joint being wide, and very straightly lopped-off (or trun-

cated) in front, by its club being rounded, compressed,

and exceedingly solid, by its four anterior coxe being

very nearly contiguous, by its femora (particularly the

front pair) being a good deal thickened, and by its tarsi

(the basal joint of which is appreciably elongated, and the

third one simple) being slender and filiform. The only

species of it which had hitherto been made known occurs

at Madeira,—where I have met with it (though very

rarely) crawling on the inner walls of houses (where I

have little doubt that it fed upon the old planks and

rafters), and where the late Mr. Bewicke formerly cap-

tured several examples of it amongst decayed, tinder-like

38 Mr. T. Vernon Wollaston on the

wood in a neglected out-house. I believe, therefore, that

its mode of life is very similar to that of Pentarthrum

and Mesozxenus; and if this be the case, I am the less

surprised that Mr. Lewis should have detected a second

representative of the genus in so distant a region as the

Japanese archipelago.

The present Hexarthrum very closely resembles the

HH. capitulum, which has been observed hitherto only in

Madeira; it is, however (judging from the single example

now before me), a little smaller and darker, its rostrum is

not quite so thickened, its limbs are (if anything) even

more abbreviated still, its elytra (which, when viewed

beneath a high magnifying power, are not quite so appre-

ciably asperate) have their strize deeper and their punc-

tures somewhat larger; and its first and second abdominal

segments are not quite so distinctly separated from each

other by a sutural line. The unique example from

which the diagnosis has been compiled was captured by

Mr. Lewis at Hiogo, in the island of Nipon.

by the shortness and thickness of its rostrum (which is

nevertheless parallel, and not triangular as in Stenoscelis),

by its thickened antennz having their scape elongate and

very robust, their funiculus short, and their club extremely

large, rounded, and abrupt, by its tarsi (the first joint of

which is lengthened, and the third bilobed) being rather

broad and pubescent, and by the fact of its legs being

subequally distant at their base,—the anterior pair being

less approximated, and the hinder ones more so, than is

usually the case iu the Cossonide. And it is further

remarkable for its body (which is nearly cylindrical, and

with the eyes prominent) being sparingly clothed beneath

with a fine and short pile; and for its front tibiz being

somewhat widened, flexuose, and robust, with their apical

hook largely developed.

In addition to the characters to which I have just called

attention, the present somewhat Hylastes-like Cossonid

may be further known by its dark hue, and by its opake

and closely, but not very coarsely, sculptured surface (the

head and prothorax of which are minutely alutaceous, as

well as punctured), and by its elytral strize being deep,

but rather lightly punctured, with the interstices broad in

front, narrower and more convex behind, transversely

rugulose, and branded with a longitudinal row of very

distinct punctules,—a type of sculpture with which we

are very familiar in certain members of the Hylesinide.

Two examples of it were beaten by Mr. Lewis, “ out of

brushwood,” near Nagasaki, in the island of Kushiu, on

the 22nd of April, 1870.

The unique example from which I have drawn the above

structural characters is one of the most important and

interesting of all the Japanese Cossonide which were

collected by Mr. Lewis, as supplying a second representa-

tive of a remarkable group which has hitherto been ob-

served only at St. Helena and the Cape of Good Hope ;

and it is the nearest true member of the Rhyncophora (as

yet made known) to the closely-allied Hylastideous forms

of the Scolytide,—its somewhat short, ovate-cylindric

outline, and excessively abbreviated, thick, subtriangular

rostrum, in conjunction with its obsolete scrobs, its ap-

proximated four anterior coxe, and the fact of its elytra

being rather obtusely-shortened, or bent down, behind,

where they are besprinkled with tuberculiform asperities,

42 Mr. T. Vernon Wollaston on the

being strongly suggestive, at first sight, of such groups as

Hylastes and Dendroctonus. In other respects it may be

known by its bald, but coarsely sculptured, surface ; by

its eyes being large, yet entirely sunken or depressed; by

its antenne being excessively short (more particularly as

regards the scape, which projects very little beyond the

lateral edge of the rostrum), with their first funiculus-

joint large and transverse-quadrate, whilst the rest are

very abbreviated, though increasing gradually (from the

excessively minute basal one) in breadth, and with their

club rounded, solid, and abrupt; by its metasternum and

first abdominal segment being less elongated than is usual

amongst the Cossonide ; by even its hinder coxe being

but slightly separated ; by its legs being rather slender,

with their tibial hooks elongate and powerfully developed ;

and by its tarsi being likewise much lengthened, but at

the same time extremely thin,—with the basal and apical

articulations comparatively long, the third one hardly at

all expanded, but nevertheless minutely bilobed, and the

claws very conspicuous.

Although in its generic details unmistakeably identical

with the Stenoscelis hylastoides, from St. Helena and the

Cape of Good Hope, the present insect is a little blacker

only more shining but very much more deeply and coarsely

Cossonide of Japan. 43

(and not so closely) punctured, and the sculpture of its

elytra (which have their region immediately surrounding

the scutellum depressed into a sort of abbreviated, pos-

teriorly-evanescent channel) is quite different,—their strize

(instead of being obsolete) forming deep crenated grooves,

with the interstices consequently (although broad) costate

and convex ; and there is no appearance of the coarse

transverse rug@ which roughen their anterior half in that

insect. The underside moreover is very much more grossly

punctured, with the first abdominal segment a trifle shorter

(it being subequal in length to the second) ; and its antennze

are even still more abbreviated than those of the S. hy-

lastoides (particularly as regards their scape), with the

first funiculus-joint broader and shorter, and the remaining

six gradually more widened and transverse, whilst the

capitulum is perhaps (if anything) even larger, and more

rounded and abrupt.

The unique specimen from which the description has

been compiled was taken by Mr. Lewis, during August,

1870, off an old fir-tree at Hiogo, in the island of Nipon.

III. The Water Beetles of Japan.

By Davin SHarp, M.B.

[Read 6th January, 1873.]

My object in this paper is to enumerate the species of

Dytiscide and Hydrophilidz found by Mr. George Lewis

in Japan. To enable me to do this Mr. Lewis has en-

trusted me with the whole of the specimens belonging to

these families, captured by him during his residence in the

Japanese islands. To the students of the European fauna

these Japanese insects are of very great interest: the

number of species common to Kurope and these far distant

islands is by no means inconsiderable; other European

species are represented in Japan by closely allied forms,

and some of our larger genera possess there numerous

species. Mingled with these European forms we find a

large proportion of quite Eastern genera and species. It

must be remembered that we know comparatively little of

the beetles of central and eastern Asia, especially of those

parts contiguous to the Japanese islands, so that at present

we are not in a position to form any correct opinion as to

what proportion the European forms bear to the eastern

ones in these parts. It will probably, however, ultimately

be found that the faunas of the eastern and western portions

of the old world gradually merge into one another, and

should really be considered but asone fauna. The species

here enumerated belong to twenty-five genera, of which

three are unrepresented in the European or Mediterranean

fauna ; these three are all genera of a wide distribution.

This species is closely allied to the European C. Reselii ;

the sculpture of the female is very similar in the two species.

C. japonicus is considerably larger, broader, and more

convex ; the upper surface is less green in colour than in

Reselii. The large and well defined dark mark on the

breast, and the dark sutures of the under surface, are also

good points of distinction. In the female the dilatation of

the epipleurz of the elytra near the base is very remark-

able, and much greater than in Reselii. Abundant*

throughout Nipon and Kushiu.

2. Cybister Lewisianus, n. sp. Convexus, ovatus, antice

Femina latet.

This species is not at all closely allied to any described

species I am acquainted with; it belongs to Aubé’s sec-

tion b, having the sides and epipleurz of the elytra yellow,

without any intersecting dark colour. The antenne are

yellow, with the four or five apical joints pitchy, except at

their extremities. Palpi yellow, with the apical jomt a

little darkened. Head of a dark olivaceous colour, with

the labrum, and a broad triangular mark above it, yellow ;

the orbit of the eyes is also yellow, narrowly so behind,

but at the front part, where it is connected with the other

yellow mark, broadly so ; it appears to be quite smooth

and shining, but, when examined with a strong magni-

fying power, is found to be very finely coriaceous, and to

have other larger, fine points sparingly scattered over it.

The thorax is broadly margined with yellow; it has the

usual punctures at the sides and front, and is sculptured

in a similar manner to the head, but the fine scattered

points are even smaller and less numerous. The scutellum

is yellowish in the middle. The elytra are of a dark

olivaceous colour, with a bright yellow margin ; this stripe

is a little dilated at the extreme base ; it is narrowed in its

posterior third, and a little before the extremity are a few

_ * I am greatly indebted to Mr. Lewis for enriching this paper with

information as to the localities, and rarity or abundance of the species

mentioned in it.

obscure yellow points not distinctly connected with the

stripe. ‘The three usual lines of punctures are very dis-

tinct, the external row less so than the two others; the two

or three basal points of the external row are placed in the

yellow lateral stripe, the three or four following ones just

at itsedge. The underside of the head is pitchy red, with

the parts of the mouth yellowish. The prosternum is red-

dish-yellow ; the front legs are entirely yellow; the middle

of the breast is reddish; the intermediate portion yellow ;

the extreme outer margin (very narrowly) black. The

middle legs are yellow, with the tibiz slightly darker than

the femora; their tarsi pitchy black; their outer claw

larger than the inner one. The abdomen is reddish; the

hind margins of the segments narrowly pitchy; the ex-

treme sides also a little pitchy, and the basal segments with

a pale spot at the sides. The hind femora are reddish ;

the tibize and tarsi pitchy black; the spurs of the former

reddish.

The much more convex form, and the different colour

of the insect beneath, will prevent this species being con-

founded with any of the forms of C. tripunctatus. It is

also very different in form from C. scutellaris, from which

morever the unequal claws of the intermediate tarsi readily

separate it (as far as the male sex is concerned, at any

rate). A single specimen only has been found, at Mino,

near Osaka.

3. Cybister tripunctatus, Ol. Abundant in Nipon and

Kushiu. These Japanese specimens cannot be considered

specifically identical with our European C. africanus,

which is now considered a form of tripunctatus ; they

may indeed ultimately prove to be a distinct species from

any yet described ; but it would be premature to consider

them so at present, so much yet remaining to be done for

the accurate discrimination of these difficult and variable

species.

4. Cybister brevis, Aubé. Abundant in Nipon and

Kushiu. This species was described by Aubé from a

single female individual. He supposed the male would

not possess the remarkable punctuation on the head and

thorax which he described in the female; but in this he

was wrong, the sexes are similar in every external point

except the structure of the tarsi.

5. Hydaticus Adamsi, Clark, Rather rare; under

48 Mr. David Sharp on the

stones on Mitsuyama, Nagasaki, and from ponds at Osaka.

This species has been identified by Mr. Lewis, by com-

parison with specimens in the British Museum.

6. Hydaticus vittatus, Fab. Very common in Kushiu

and Nipon. It is quite probable that several closely allied

species are confounded under the name of vittatus. We

must wait, however, till series of individuals from various

localities can be examined before deciding this point.

7. Hydaticus rufulus, Aubé. Nagasaki and Hiogo.

This species is united in the Munich catalogue with our

European H. Leander, but I entertain doubts as to the

correctness of this.

8. Hydaticus grammicus, Germ. Nagasaki.

9. Hydaticus japonicus, n. sp. Breviter ovatus, con-

vexus, capite prothoraceque testaceis, nigro signatis, elytris

nigricantibus flavo-irroratis ; subtus nigro-piceus, protho-

racis lateribus, prosterno, pedibus quatuor anticis epi-

pleurarumque basi testaceis, pedibus posterioribus nigris

femoribus flavo-ornatis. Long. 53—6}4 lin.; lat. 32—

4 lin.

Mas, tarsis anticis et intermediis dilatatis.

This species will be best described by a comparison

with H. cinereus, to which it is closely allied. The

colouring of the upper surface is just the same as in cinereus,

but beneath, japonicus is very much darker, and the form

of japonicus is very much shorter than that of cinereus.

The female differs from the male by its simple tarsi, by

possessing a few obscure lines or strigz near the sides of

the thorax, and also by the yellow band of the middle of

the thorax being narrower than in the other sex.

Very abundant in the fens of Osaka and the ponds of

Hiogo.

This very distinct and interesting Agabus is allied to

both A. bipustulatus and fuscipennis, while in the struc-

ture of the claws of the hind feet it makes an approach to

Ilybius. It is readily distinguished from fuscipennis by

the larger size and the rounded base of the thorax, as well

as by the distinct reticulation of the elytra. It is broader

and more rounded at the sides than is A. bipustulatus,

and the reticulation of its upper surface is quite different

from that species, being much finer, and the direction of

the lines transverse rather than longitudinal; the sculp-

ture of the under surface much resembles that of dbipustu-

latus. The shape of the lateral laciniz of the metaster-

num is rather close to that of A. fuscipennis, but the depth

of the hind coxe is considerably more than in fuscipennis ;

this arises both from their upper margin being more

strongly arched, and their lower margin more transverse

(that is, less oblique in direction) than in fuscipennis.

The claws of the hind tarsi are closely applied to one

another, and almost straight, the outer one is evidently

smaller than the inner one; the disparity, however, is

much less than in I/ybius. The species is rather variable

in its colour.

Osaka and Nagasaki. Common.

_ This species has all the structure assigned by Thomson

to the genus Platambus. It is readily distinguished from

A. maculatus by the shining and nearly unsculptured

upper surface, as well as by the different markings; in

this latter respect it appears more allied to A, sinuatus,

Aubé (from Asia Minor), a species which I have not seen,

but which, judging from description, should be similar in

sculpture to maculatus, and therefore very different from

pictipennis ; sinuatus has, moreover, at the sides of the

elytra a continuous pale band instead of the three spots of

pictipennis. The colour, both of the upper and under

surfaces, varies according to the degree of maturity.

Four specimens from Hiogo, under stones in the water-

courses.

13. Agabus japonicus, n. sp. Ex affinitate A. palu-

dosi: ovalis, supra nitidus, levis, capite prothoraceque

nigro-ceneis, elytris fuscis: subtus niger. Long. 33—

32 lin.

Mas, tarsis anticis vix dilatatis, unguiculis squalibus

simplicibus; tarsis posterioribus articulis tribus basalibus

subtus minus dense setigeris.

This species is closely allied to A. paludosus; it is

broader and more rounded at the sides, the thorax is of

an obscure brassy colour, and not paler at the sides, and

its hind angles are more acute; the impressed points on

the elytra are finer.

The underside is black, with the epipleure pale at the

base. The antenne and palpi are reddish-yellow, the

four front legs are reddish, with the femora infuscate; the

femora and tibiz of the hind legs are blackish, their tarsi

reddish. The structural characters of the male are similar

to those of paludosus.

Hiogo and Nagasaki.

14. Agabus dissimilis, n. sp. Ex affinitate A. spilop-

teri, Germ.—Late ovalis, depressus, niger, nitidus, subti-

lissime reticulatus ; capite, prothoracis macula ad angulum

anteriorem, antennis, pedibusque quatuor anticis rufo-

testaceis; pedibus posterioribus piceis. Long. 24 lun. ;

lat. 14 lin.

Variat, elytris plus minusve testaceo-ornatis.

This insect has more the form of a large Laccophilus

than of an Agabus. It is allied to 4. spilopterus, Germ.

It is very shining, the upper surface is finely reticulate,

the head is yellowish, the part adjacent to the inner mar-

gin of the eye broadly marked with black. The thorax

has a large yellowish mark at the front angle. The elytra

are also marked with yellow, but apparently in a very

variable degree ; there being either a narrow yellow trans-

verse band close to the base; or this is absent, and re-

placed by one or two small pale dots; just in front of the

apex there is always a yellow spot, and the parts towards

the sides and the extremity show also some obscure and

Water Beetles of Japan. 51

variable yellow marks. The lateral laciniz of the meta-

sternum are extremely narrow.

Three examples of this interesting species have been

submitted to me by Mr. Lewis, without particular locality

being indicated.

15. Copelatus, spec. ? There are two specimens of this

genus in the collection, one male (from Osaka), one female

(from Nagasaki); I have been unable to satisfy myself

that they are certainly the same species, and I do not there-

fore describe them. Mr. Lewis feels sure they are distinct

species, and I think it very likely to prove so.

16. Ilybius apicalis, n. sp. Oblongo-ovalis, supra

zeneus, margine pallescente ante apicem trihamato; subtus

ferrugineus; metasterni laciniis perangustis. Long. 44

lin.; lat. 23 lin.

This species resembles in form J. fuliginosus, but is

readily to be distinguished by the band of the elytra,

which has a large treble spot attached to it at the ex-

tremity, and by the very different shape of the side wings

of the metasternum. ‘The upper surface is brassy, with

the front of the head, the sides of the thorax and elytra

yellowish; the pale band of the elytra is divided in its

posterior part by a darker line, and a little behind the

middle there is close to the band a short pale dash; the

sculpture of the upper surface is very fine and dense.

The under surface is of a rusty colour, the antennz and

legs reddish-yellow. The anterior margin of the hind

coxee is very much extended forwards, more so even than

in fenestratus.

The structure of the claws in the male does not differ

from that of the female; the outer claw of the hind foot

is slender and but little curved.

Ponds in sandy districts. Hiogo and Simabara. Rare.

17. Hydrocanthus politus, u. sp. Ovalis, nitidus,

levis, testaceus, elytris fuscis, testaceo-maculatis; pro-

sterno pectorisque parte elevata fortiter punctatis. Long.

13 hn. ,

Entirely shining yellow, with the exception of the ely-

tra, which are blackish, but largely marked with yellow;

these markings consist of two very large yellow spots at

the base, and a transverse band placed a little behind the

middle and interrupted at the suture, the extremity also

is pale. The upper surface is very shining and quite

without sculpture, while the whole of the raised portion of

the under surface is strongly punctured.

Common in ponds at Hiogo.

18. Noterus japonicus, n. sp. Convexus, brevior, ni-

tidus; elytris fere sine punctis majoribus impressis. Long.

2 lin.

Mas, antennis subsimplicibus; articulo 5° vix incras-

sato, 8-10 angulo externo superiore acuto.

Closely allied to WV. levis; just a little shorter and more

convex than that species, and with the punctures of the

elytra not quite so fine. The structure of the antennz in

the male is, however, very different from that of NV. levis.

They appear at first sight not to differ in the two sexes,

but when a careful examination is made it is found that

the antenna of the male is a little broader than that of the

female, and that its fifth joint is just a little produced in-

wardly, and that joints 8—10 have each the upper and

outer angle distinctly acuminate and a little produced.

Common at Nagasaki.

19. Laccophilus Lewisius,n. sp. Forma et statura fere

L. testacei; testaceus, elytris nigro-lineatis, lineis haud

flexuosis, aliquantum interruptis ut macule pallidz ad basin

et ad marginem videantur. Long. 24 lin.; lat. 1? lin.

About as long as L. testaceus, but just a little narrower

and more convex than that species. The maxillary palpi

are yellow, pitchy at the extremity; the antennz are

yellow, with the last joint pitchy, and each of the three or

four penultimate joints is a little clouded at the apex.

The head is yellow and unspotted. The thorax is yellow,

the front margin in the middle and the hind margin have

an extremely short (i.e. in the longitudinal direction of

the thorax) black mark; the front one does not extend

quite to the inner margins of the eyes, the hind mark is

not well limited in its lateral extension; the base of the

thorax in the middle is formed as in L. testaceus. The

elytra are yellow, much marked with black; the black

marks consist of three or four pairs of lines, the lines form-

ing each pair meeting together a little before the base ;

externally, and also towards the extremity, these lines are

connected with some other more or less linear markings,

and the whole of these dark marks are so disposed and

interrupted as to give an appearance of the elytra pos-

Water Beetles of Japan. 53

sessing some yellow spots; these spots being—one on each

elytron near the suture at the base, three large ones at each

outer margin, and the extremity of the two wing-cases.

The reticulation of the upper surface is much more evi-

dent than in L. testaceus.

A single specimen of this pretty species has been taken

at Kobé, by Mr. Lewis.

20. Laccophilus flecuosus, Aubé. Common at Naga-

saki. This species was described by Aubé from India.

Though I have not seen any individuals from that country,

I possess specimens from Persia agreeing with Aubé’s de-

scription, and these I consider the same species as the

Japanese individuals.

21. Laccophilus difficilis, n. sp. Ovalis, pallidus, elytris

paulo obscurioribus, antennis palpisque apicibus nigro-fuscis;

prothorace basi medio sat acute producto. Long. 2 lin.

This species is greatly allied to our European interruptus,

testaceus, and obscurus ; the base of the thorax in the middle

is rather more pointed than in interruptus or testaceus,

rather less than in obscurus ; from interruptus its unspotted

elytra and the dark extremity of the palpi and antenne,

from testaceus the latter character, and its smaller size and

rather narrower form, and from odscurus its shorter and

broader form, will also distinguish it; our European obscurus

has the extremity of the palpi and antennze darkened in

only an obscure degree, while this character is very con-

spicuous in the Japanese insect. An examination of the

underside shows that the length of the dilated portion of

the hind coxe is, in proportion to their width, much less

than in obscurus.

Common at Nagasaki.

22. Laccophilus kobensis,n. sp. Ovalis, testaceus, ely-

tris obscure fuscis, basi margineque sat distincte testaceo-

maculatis; prothoracis basi medio minus acute producto.

Long. 12 lin.

This species is smaller than either LZ. interruptus or

obscurus, and is more allied to the former than the latter ;

it is somewhat similar in colour to L. interruptus, but the

spots are not quite so distinctly limited, and the angle of

the base of the thorax is just a little more acute. The much

less acute angle of the base of the thorax, the much shorter

54 Mr. David Sharp on the

and more rounded form, and the more distinctly spotted

elytra, will prevent its being confounded with L. obscurus.

Probably common at Kobé (Hiogo).

23. Hyphydrus japonicus,n. sp. Rufo-testaceus, capite,

prothorace, elytrisque nigro-variegatis. Long. 14—24 lin.

Mas.—Nitidus fortiter punctatus.

Femina.—a, opaca obsolete punctata.

6, ut in marem nitida et punctata.

This species is closely allied to H. variegatus. It is,

however, rather smaller, proportionally a little broader, and

more acuminate both in front and behind; the black mark-

ings are similar to those of H. variegatus, but leave a larger

portion of the upper surface yellow. The punctuation is

not so dense as in variegatus, and is more distinctly divided

into large and small punctures. I am not aware that in

variegatus a male-like form of the female has been obtained,

but in japonicus the two appear to occur in about equal

abundance. ,

H. japonicus is variable in size, in the extent of the

black markings of the head and thorax, and also in the

sculpture of the upper surface, but none of the varieties I

have seen could at all be united with variegatus.

Common at Nagasaki and Hiogo.

24. Hydroporus japonicus, n. sp. Ex affinitate H.

minutissimt.— Elongato-ovalis, subdepressus, supra rufo-

testaceus, capite prothoraceque basi plus minusve infus-

catis; elytris distincte punctulatis, fasciis longitudinalibus

plus minusve coalescentibus nigris; subtus piceus. Long.

1 lin.

This little insect belongs to the same section of the

genus as minutissimus and its allies; it has a deep im-

pressed mark on each side of the thorax, and this is con-

tinued on the basal part of the elytra. The antennz are

itchy, largely yellow at the base. The head is yellowish.

he thorax is yellowish with the base clouded in the middle,

and with the dark part sparingly but distinctly punctured ;

the impressed lines are deep; it is a little rounded at the

sides, its outline not continuous with that of the elytra ;

it is nearly as broad at the front angles as at the hind ones.

The elytra are scarcely broader at their base than the

thorax ; they are a little rounded at the sides and pointed

behind ; they are of a yellowish colour, but much marked

with black; the suture, a transverse band at the base, an

elongate mark, not united with the sutural one except near

the base, a mark below the shoulder, and another one be-

hind this near the outer margin, black; they are rather

strongly punctured on the disc. The legs are yellow. The

under surface is blackish, with the breast réd in the middle.

Abundant at Nagasaki.

25. Cnemidotus intermedius. atus, testaceus, indis-

tincte nigro-maculatus, elytris fortiter striato-punctatis ;

laminis coxarum fortiter punctatis, apice valde et acute

dentatis. Long. 14 lin.

Closely allied to C. cesus and rotundatus, and in form

intermediate between the two; easily distinguished from

either by the much more closely punctured ventral plates,

and the large and very pointed tooth at their extremity.

Thorax with a few punctures near the hind angles, some

finer ones about the front, and an irregular row of larger

ones along the base, this row terminating some distance

from the sides by two or three larger punctures placed

close together. LElytra yellow, with five or six indistinct

black spots, punctate-striate, the punctuation very coarse

at the base and fine at the extremity ; the punctures black,

the first: of each row very large and deeply impressed.

Abundant at Nagasaki.

26. Haliplus japonicus, n. sp. Rufo-ferrugineus, capite

infuscato, prothorace basi utrinque impresso, elytris fortiter

striato-punctatis, fusco-lineatis. Long. 14 ln.

Allied to Hi. ruficollis and about the same size, but

scarcely so broad at the shoulders; the punctures of the striz

of the elytra much larger, the first puncture of the third,

fourth, and fifth rows from the suture distinctly larger than

the rest, the head infuscate and the elytra unspotted. It

is not likely to be confounded with any other species I

know.

Two specimens from Nagasaki.

GYRINIDZ.

27. Gyrinus japonicus, n. sp. Ovalis, convexus, supra

chalybeo-niger, lateribus zenescens, elytris equaliter punc-

tato-striatis, punctis apice subtilioribus ; subtus niger,

prothoracis et elytroruam margine inflexo eneo-ferrugineo.

Long. 23—34 lin. ; lat. 13 lin.

56 Mr. David Sharp on the

Allied closely to our European species marinus and

Suffrianit. It is rather broader and more convex than

marinus, and it differs from it by the punctures of the

strie, which become finer towards the extremity, and also

by the absence in both sexes of the fine sculpture of the

upper surface which is so distinct in the females of mari-

nus. It is more nearly allied to Suffriani, and it much

resembles that species in the punctuation of the elytra,

but it is so much larger and broader that the two cannot

be confounded. The internal striz of the elytra are quite

distinct, but they are a little finer than the lateral ones.

The claws of the tarsi are red and unspotted ; the inflexed

margin of the prothorax is reddish; the epipleuree of the

elytra are zneous, a little rufescent in the middle in their

basal half; the femora of the four hinder legs are pitchy in

the middle.

Abundant at Hiogo and Nagasaki.

Obs.— Besides the specimens described above, I have

seen two other specimens (¢ and ¢) of a Gyrinus from

Japan (one in Mr. Lewis’s collection from Nagasaki, and

one from another source in my own). They may prove

to be a distinct species from the above, being considerably

smaller, having the inflexed margin of elytra and thorax

red, and the femora entirely red. I should like to see

more specimens to confirm their claim to be considered a

distinct species. It is possible they may be the species

intended by Motschoulsky under the name of G. curtus,

but I have not been able to consult his description.

28. Dineutes marginatus, n. sp. Ovalis, supra metal-

lescens, flavo-limbatus, subtus cum pedibus testaceus,

elytris quadrispinosis, spinis internis externis haud longio-

ribus. Long. 4—4$ lin. ; lat. 21—23 lin.

Mas abdomine simplice.

Fem., abdomine segmento 2° medio valde rotundato-

producto.

Allied to D. spinosus, Aubé, but larger and broader,

and with the internal tooth on each elytron not broader

than the external one. The upper surface is metallic,

with a yellow margin extending from the front of the

thorax to the first tooth of the elytra; internal to this is a

greenish stripe, and inwards from this two dark purplish

coppery stripes, these stripes being separated from one

another by cbseure strie; at the base, near the suture,

there are also traces of two of these dark copper stripes:

Water Beetles of Japan. 57

when well examined, the elytra are found to possess traces

of a sparing and obsolete scattered punctuation. Each

elytron is armed near the extremity with two sharp mode-

rately long spines, one placed quite at the extremity near

the suture, the other at the side at a five or six times

greater distance from the suture. The under surface, as

well as the legs, is entirely pale yellow.

Abundant in Nipon and Kushiu. I also possess speci-

mens of this species from Mantchuria.

HYDROPHILIDZ.

29. Hydrophilus cognatus,n.sp. Ovalis, nigro-olivaceus ;

palpis antennarumque basi testaceis, harum clava fusca ;

elytris sutura spina apicali minut instructis; abdomine

segmentis medio carinatis. Long. 17—18 lin.; lat. 9 lin.

Mas, tarsis anterioribus articulo 5°, precedente paulo

latiore.

This species is greatly allied to our European HZ. piceus,

but is quite distinct therefrom; it is about the size of

aterrimus; it has a minute spine at the extremity of the

elytra, as in piceus, and all the segments of the abdomen

are carinated along the middle. The sternal spine is

deeply canaliculate in front, and again before the ex-

tremity ; the portion projecting over the base of the

abdomen is unmistakably shorter than in H. piceus ; this

character, with its smaller size, will enable the female to

be distinguished from that of H. piceus ; the male cannot

be confounded with H. piceus, the slightly dilated joint of

the front tarsi and the comparatively small and less un-

equal unguiculi being very different from our European

species.

Abundant in Nipon and Kushiu.

I possess this species from China and Formosa. I have

not been able to see Motschoulsky’s description of H.

acuminatus from China.*

30. Hydrophilus japonicus, n. sp. Anguste - ovalis,

minus convexus, supra viridi-olivaceus, plus minusve

denter angulatis, segmento anali omnino ecarinato. Long.

12 lin. ; lat. 5—54 lin.

Mas, tarsis anterioribus apicem versus leviter dilatatis,

unguiculis sat elongatis magis curvatis.

This species belongs to a group differing materially from

H. piceus and its allies by the entirely pubescent abdomen;

the species of the group form a gradual passage to the genus

Temnopterus of Solier. The outlines of this insect are

more continuous than in piceus: the maxillary palpi have

the apical joint shorter than in piceus, and a little truncate at _

the extremity : the sculpture of the elytra does not become

more distinct towards the extremity : the extreme apex of

the elytra is not truncate, but in each it is just a little

separately rounded, and the suture has a minute denticle.

The sternal keel is strongly channelled, and projects back-

wards nearly as far as the hind margin of the third ab-

dominal segment. The segments of the abdomen, except

the apical one, are a little carinate, or rather angulate, in

the middle. The legs are pitchy black; the hind femora

qometimes reddish.

Rare ; found at Ipongi, near Nagasaki, in paddy fields.

I possess a very closely allied species from Mantchuria,

and some other allied species from the Philippines; these

latter have the abdominal segments in the middle fur-

nished with some sparing sete.

31. Hydrochares affinis, n. sp. Ovatus, sat convexus,

his femoribus basi nigris; abdominis segmentis lateribus

rufo-maculatis, femoribus posterioribus subtus levigatis.

Long. 84 lin.; lat. 44 lin.

Closely allied to our European species caraboides and

Jlavipes ; it is of the same size and form as H. caraboides,

and has the punctuation of the upper surface similar, but

it is distinguished therefrom by the red legs, and the

impunctate hind femora; from H. flavipes it is distin-

guished only by its larger size and broader form, and

by the fact that in H. affinis the striz of the elytra are

quite distinct, though very fine, whereas they are very

nearly absent in flavipes.

I have seen only two specimens of this species; one

of them, very soft and immature, has the upper surface

olivaceous, the other is black.

Found in a pond at Hiogo.

32. Hydrochares flavipes, Stev. var. A single specimen

found at Nagasaki is so close to our European H. flavipes,

that I think it may perhaps prove a mere variety thereof.

33. Sternolophus fulvipes, Mots.?* A species of Ster-

nolophus is common in Nipon and Kushiu; though I

have not been able to see Motschoulsky’s description of

S. fulvipes, I think it so likely that this insect is what he

mtended thereby that I do not describe it as new.

Long. 3 lin. ; lat. 12—12.

Rather larger and notably broader than P. testaceus.

Palpi yellow. Head black, with a narrow, but distinct,

yellow spot on each side in front of the eye; closely and

rather strongly punctured. Thorax black, with the sides

very distinctly yellowish, the yellow colour also extending

along the front margin, so that the extreme front margin

is pale; the pale colour also extends inwards along the

hind margin, but more indistinctly; closely and distinctly

punctured, on each side with some larger punctures form-

ing a not very distinct horse-shoe curve. Elytra black,

distinctly margined with yellow, rather strongly and

closely punctured, the punctures not quite so numerous at

the extremity as at the base; they have a sutural stria

abbreviated at the base ; they also present indistinct traces

of being striate-punctate, and moreover have three series

of larger punctures, of which the outer is not so well de-

fined as the other two. Beneath the femora are black and

pubescent, except the extremity, which is reddish and im-

punctate. The tibize are pitchy; the tarsi yellowish. The

mesosternal carina strongly elevated, acuminate below.

* J find this species cannot be reconciled with Motschoulsky’s descrip-

tion of S. fulvipes here alluded to. I am sorry to say, however, that I

cannot decide whether the Japanese insect be the same as the Indian

Maxillary palpi yellow ; the apex of the last joint slightly

infuscate. Head closely and rather finely punctured, the

front part yellow, the hind part black. Thorax yellowish,

the dise a little clouded; it is rather finely and closely

punctured, and has near each side a curved irregular patch

of larger punctures. LElytra yellowish, not so densely

punctured as the thorax, rather strongly striated, the

sutural stria not reaching to the base, and the two or foe

next to it extremely indistinct at the base; from the third

to the ninth each alternate interstice bears some larger

punctures. The underside is black, the legs yellow; the

femora darker behind, pubescent beneath, except at the

extremity of each; hind tarsi long and slender; carina of

the mesosternum largely developed, its front angle acute.

A single specimen only of this species has been taken

by Mr. Lewis at Nagasaki; this is the only Philhydrus

I have ever seen with distinctly striated elytra, though

I know several species of Helochares sculptured in that way.

36. Helochares striatus, n. sp. Ovalis, minus depressus,

rufo-testaceus, capite nigricante macula utrinque rufo-

testacea ; crebre fortiterque punctatus, elytris fortiter punc-

tato-striatis; subtus obscure rufescens, tibiis tarsisque tes-

taceis. Long. 24 lin.; lat. 14 lin.

Maxillary palpi entirely yellow, considerably shorter

than in HZ. lividus, but similarly formed. Head blackish,

yellow on each side in front of the eyes, coarsely and rather

closely punctured. Thorax with the punctuation similar

to that of the head, the lateral margin coarser behind than

in front. Elytra rather less strongly punctured than the

head and thorax, each with ten striz of rather deeply im-

pressed punctures, a short abbreviated row of punctures

between the scutellum and first stria ; the strize do not ex-

tend quite to the outside, but leave a distinct margin much

directed outwards. ‘The under surface is pubescent and

pitchy red; the elytra greatly overlap the hind body; the

mesosternum has a slightly elevated tubercle in front. The

tibize and tarsi are yellow.

I have seen but a single specimen of this very distinct

and interesting species; it was found os Mr. Lewis at

Nagasaki.

Allied to H. dilutus, Er., but not one quarter its size,

of a purer yellow colour above. The palpi are entirely

yellow. The head and thorax are closely and finely punc-

tured, the latter finely margined at the sides. The elytra

are very finely punctured, and each has a row of larger

punctures along the middle. The underside is fuscous,

the mesosternum obscurely tuberculated. The legs are

yellow, the femora pubescent except at the extremity, the

pubescent part darker in colour.

mens differ a little from our European ones, but I do not

This species is closely allied to B. signaticollis, Charp. ;

it is rather smaller than that species, and has the elytra

shorter and rather more deeply striate; it is readily dis-

tinguished by the greater extent of the pubescence on the

under surface of the femora: on the hind femur of B. sig-

naticollis the pubescence does not extend more than half

way to the extremity, while in japonicus only the apical

third is glabrous. The spots on the disc of the thorax are

small and not united in the middle, and sometimes they

are separated transversely so as to form four small spots.

Much smaller than V. inflatus, and above entirely brassy.

Maxillary palpi yellow, the last joint about twice as long

as the preceding one, pitchy at its extremity. Antenne

yellow, with the club dark. Head densely and finely

punctured, behind the labrum more densely and finely

than at the vertex. ‘Thorax as wide as the elytra, with

the base rounded, the posterior angles absent ; it is densely

and rather finely punctured. Scutellum narrow and elon-

gate, finely punctured. LElytra moderately densely and

finely punctured, each with ten striz deeply impressed at

the extremity, the three or four internal ones not visible

at the base. Under surface black, the mesosternum very

strongly carinated, the two hinder pair of femora pitchy,

strongly punctured and glabrous beneath. Anterior tibiz

and tarsi obscurely yellowish.

Abundant everywhere.

I possess a very closely-allied species from several locali-

ties in the Malay Archipelago.

ternis subtilioribus, palpis tarsisque testaceis. Long. 14—

2 lin.

Maxillary palpi yellow, last joint longer than the pre-

ceding one ; the antepenultimate joint distinctly thickened.

Head very broad, margined along the front, densely and

finely punctured, especially in front, and with some irregu-

larly placed larger punctures. Thorax densely and rather

finely punctured, with a few indistinct larger punctures

scattered about it. LElytra externally with some rows of

coarse punctures; the internal ones are very fine, and only

to be seen towards the extremity, where it is found that

the rows are placed obliquely, so that the inner ones end

near the suture some distance before the apex; the ex-

ternal interstices have each a row of coarse punctures, and

also some finer punctures. The underside has only an

extremely sparing and fine, scarcely visible, pubescence.

The legs are yellowish or pitchy yellow, the tarsi yellow,

the posterior tarsi slender, and not at all remiform. The

intermediate coxze are considerably separated, the meso-

sternum not carinate.

Taken at Hiogo and Nagasaki.

This insect is one of great interest from a peculiar struc-

ture of the abdomen, which has not yet been remarked.

On the abdomen being taken off it is found that the first

segment-is placed at right angles with the others (the

abdomen is perhaps flexible there), so that in life the

hinder segments are turned upwards, and leave a large

vacant space underneath the elytra. In one large speci-

men I have examined, no doubt a female, the abdomen at

first sight appears to be entirely wanting. It is very pos-

sible that this structure enables the insect to carry about

its eggs on dry land; it is, I have no doubt, at best only

a semi-aquatic species, for it is not provided with pubes-

cent portions on the under surface to retain air, as are the

more aquatic palpicorns. This peculiar abdominal struc-

ture must be considered in connection with the inflated

elytra, and also with the fact that the hind coxe are trans-

verse and largely developed, and free both above and

below; add to this, that where the posterior legs are

flexed an additional protection is given by them to the

subelytral space. Observations on the habits of this spe-

cies would, I have no doubt, be of great interest.

I am indebted to Mr. H. W. Bates for a closely allied

64 Mr. David Sharp on the :

species from China. The relationship of the genus to

Cyclonotum is evident.

43. Hydrochus japonicus, n. sp. Supra viridi-metalli-

cus, palpis piceis; subtus niger, pedibus testaceis, femorum

basi piceis; thorace foveolato, elytris interstitiis minus

evidenter elevatis. Long. 1$—1} lin.

Smaller than either of our European species, somewhat

similar in colour to H. angustatus ; distinguished by the

prothoracic fovez, which appear separated from one

another, as it were, by raised lines. Head and thorax

metallic green or blue, the latter with five or six fovex,

occupying the greater part of its upper surface, placed

very close to one another, so as to appear separated only

by narrow linear elevations; the elytra are metallic, but

not so brilliant in colour as the head and thorax; they are

coarsely, closely, and regularly punctate-striate, the third

and fifth interstices elevated, but not strongly; the fifth

also elevated at the base; the under surface is silky,

opaque, and blackish; the legs are yellow, the femora

rather darker, especially at the base.

Common at Nagasaki.

nigrum, palpis, antennis, tarsisque rufis, pedibus piceis ;

subtiliter sat crebre punctatus: elytris evidenter striato-

punctatis. Long. 34 lin.; lat. 2 lin.

The broad, comparatively short form of this species is

remarkable. The head is closely and rather finely punc-

tured, especially in front; the thorax is finely and not

densely punctured; it is fully three times as broad as

long. The punctuation of the elytra is similar to that of

the thorax, perhaps scarcely so close or distinct. Each is

also furnished with ten distinct rows of punctures; these

are coarser and more distinctly impressed at the extremity

than at the base. ‘The under surface is densely and finely

punctured, pubescent, and opaque, except the central part

of the metasternum; the prosternum is very acutely ele-

vated in the middle in front. The legs are pitchy, the

tarsi reddish.

I have seen but two specimens of this species taken at

Nagasaki, where Mr. Lewis tells me it is common in

ponds.

I possess an allied species, with punctate-striate elytra,

from Penang; in it the punctuation of thorax and elytra

is much denser.

rufis, prothorace lateribus castaneis, elytris colore variabili-

bus; dense punctatus; elytris striatis, striis postice pro-

fundioribus. Long. 13—2 lin.

This fine species is allied to C. lttoralis, but has the

anterior tibixe simple at the extremity: it is remarkable

for the dense and even punctuation of the elytra; these are

either of a chestnut colour, or black, with the margins

paler; the striz are very deeply impressed towards “the

apex. The mesosternum has the intercoxal process very

long; the prosternum is carinate along the middle, and

the basal segment of the abdomen is finely carinate ; the

whole of the under surface is pubescent and opaque, ex-

cept the pentagonal portion of the metasternum and the

mesosternal process; these are shining, and distinctly and

rather closely punctured. This and the followi ing species

evidently belong to the genus Pelosoma of Mulsant, which.

will, perhaps, ultimately have to be adopted as a good

genus.

Seaweed. Nagasaki and Amakusa.

46. Cercyon algarum, n. sp. Ovalis, leviter convexus,

nitidus, niger, antennis, palpis, pedibusque rufis; capite

prothoraceque sat crebre punctulatis, elytris striatis, striis

punctulatis. Long. 1 lin.

Allied to C. Littoralis, but with the anterior tibiz simple

at the apex, the punctuation of the interstices of the elytra

finer and more scanty ; the striz are very deeply impressed

towards the extremity. The structure of the under surface

is similar to that of C. dux, the pentagonal space very finely

and. sparingly punctured.

Of four specimens I have seen, three have the elytra black,

with only their very extremities paler; in the other speci-

men the colour of the elytra is pitchy; the species is probably

very variable in colour, like its allies; the legs are furnished

with fine short spines.

Again allied to C. littoralis, but smaller, with the anterior

tibi simple at the extremity, and the punctuation of the

upper surface finer. It is allied to the preceding species,

but is longer and very distinct therefrom by the armature

of the tibix, the spines thereon being much more largely

developed. The convexity of the alternate interstices of

the elytra towards the extremity, though only slight, can-

not be overlooked on a careful examination. The two

specimens before me are discordant in colour, one being

of a yellowish colour, the other pitchy, with the margins

and extremities of the elytra paler.

13 lin.

This species differs from the others of the genus, by the

intermediate legs being separated only by a thin lamina, as

in the genus Philly ydrus. Maxillary palpi yellow, with the

last joint infuscate. Antenne with the base yellow, the

club fuscous and very elongate. Head black, rather strongly

and closely punctured. Thorax pitchy, more transparent

along the front and sides, rather closely and strongly

punctured. Scutellum very narrow. Elytra pitchy, paler

yellow at the sides and extremity, deeply punctate-striate,

the striz deeply impressed behind, the punctuation of the

insterstices distinct, but more sparing than that of the head

and thorax. The legs are yellow, with the tarsi long; the

tibix of the four front legs rather strongly, the hind ones

more feebly, spined.

I have seen but two individuals of this very distinct

species. Though it has completely the appearance of a

Jercyon allied to Littor alis, it may possibly prove the type

of a new genus. Found in dung at Hiogo.

interstitiis minus crebre punctulatis ; tibiis anticis integris.

Long. 14—14 lin.

This insect is similar in form and colour to Megasternum

boletophagum, but is greatly larger; it is similar to that

species in the structure of its under surface, but has the

anterior tibiz: simple at the extremity ; as this character is

only a sectional one in Cercyon, it cannot here be con-

sidered of sufficient importance to justify the establishment

of a new genus.

The head and thorax are rather strongly and closely

punctured, the latter with a row of larger punctures placed

along the base. The elytra are moderately strongly punc-

tate-striate, the insterstices very finely punctured. The

under surface is coarsely and closely punctured.

Two specimens without special locality.

IV. Catalogue of the Phytophagous Coleoptera of Japan,

with descriptions of the species new to science.

By Josrern 8S. Baty, F.L.S.

[Read 2nd December, 1872. ]

THE great majority of the species which I have enumerated.

or described in the present paper were collected by Mr.

George Lewis during his residence in Japan. It is, un-

doubtedly, the largest collection of Japanese Phytophaga

ever brought to this country ; but in order to make the list

of species more complete I have added the descriptions

of a few insects previously existing in my own cabinet,

which do not appear to have been met with by him. Here

and there, under the various genera, I have made a few

remarks on the geographical distribution of the species be-

longing to each; and it is my intention in a second paper

to give a tabular list, similar to the one given by Mr. F.

Smith in his paper on the Hymenoptera collected by Mr.

Wallace, in order to show, as far as possible, their geo-

graphical range.

Fam. DONACIDZ.

Genus Donacta, Fabr.

The single species taken by Mr. Lewis in Japan has a

very wide range ; it differs both in coloration and size ; it

is probably the Donacia Javana, Wiedeman.

Hab.— Nagasaki and Hiogo, Japan; also the coast of

Tartary and Northern China. Found on the Chry-

santhemum.

Forehead slightly raised, coarsely punctured, impressed

in the middle with a deep longitudinal eroove. Sides of

thorax broadly constricted in ‘the middle, a perpendicular

space occupying the deepest part of the constriction,

coarsely rugose ; upper surface impressed with large

deep punctures, which vary greatly in number; in most

specimens they are crowded and confluent on ‘the disk,

having a central vitta free from punctures; the surface on

cither side this line is generally depressed, having the

vitta itself raised and subcostate; the space between the

punctures minutely but not closely punctured; in many

specimens, especially the large ones, the larger punctures

are much less numerous, and are scattered at distant inter-

vals over the surface. Scutellum subquadrate, its surface

impressed with shallow punctures, and sparingly clothed

with adpressed sericeous hairs. Elytra strongly punctured

at the base; the punctures much smaller and less deeply

impressed behind the middle; basilar space bounded

beneath by a broad, well-defined excavation, which does

not extend quite to the suture, but occasionally curves

upwards along its edge to the scutellum. Body beneath

black ; abdomen clothed with very fine sericeous hairs;

last three segments testaceous.

This insect (previously described by me from specimens

brought from Northern China) varies so greatly in size

and sculpturing of thorax, that I have thought it best,

after examining the fine set of individuals placed in my

hands by Mr. Lewis, to make a fresh diagnosis of the

species; in the majority of the larger specimens from

Japan the abdomen is entirely black; but I possess

others, equally large, from the coast of Tartary, in which

the apex of the abdomen is testaceous. I presume, there-

fore, that this is the normal colouring, the black apex

being only a variety. All the specimens that I have

examined, however they may differ in size or in the punc-

turing of the upper surface of the thorax, agree in having

a broad longitudinal space (much more distinct than in

LL. coronata), occupying the deepest part of the lateral

constriction, coarsely rugose.

Phytophagous Coleoptera of Japan. 73

This insect is so exactly similar in form and sculpturing

to the two preceding species, that a detailed description is

not necessary; its forehead, however, is flatter and less

deeply grooved. I only know three specimens, all ? ;

they agree entirely in coloration, and in having the inner

surface of the intermediate tibize armed just before its

middle with a small ill-defined tooth; this character will

at once separate it from the two preceding insects. All

the three species are very closely allied to LZ. coroman-

deliana, Fabr.: they may be distinguished from it by the

following character amongst others: the deepest part of

the lateral constriction of the thorax in LZ. coromandeliana

and its varieties is entirely smooth, whilst in the three

species before us it is always more or less rugose ; also in

L. coromandeliana the inner surface of the intermediate

tibia in the g (not the ¢, as in LZ. coronata) is armed

with a small tooth.

Hab.— Nagasaki, found on the Dioscorea.

Head strongly constricted on either side behind the

eyes, the latter deeply notched ; forehead impressed with

constriction ‘smooth ; upper surface transversely depressed

in front of the base; disk very convex, somewhat sub-

globular, impunctate, with the exception of a double row

of very fine punctures, which form a longitudinal line down

the middle. Elytra oblong, parallel : ; above convex,

slightly depressed below the basilar space, the latter

slightly elevated ; surface deeply punctate-striate, inter-

spaces towards the apex subcostate. Legs moderately

robust.

L. honorata must stand close to L. Lewisii and its

allies: it may be known by the longer thorax, the smooth

Mr. Lewis agreeing exactly in their markings.

I have no doubt but that the description by Swartz in

variety of this species with immaculate thorax. The

name, however, cannot stand, having been previously used

by Olivier for an insect belonging to the same genus.

This insect varies greatly in the colouring of its under

surface ; the form of the apex of the mesosternum is also

very variable; in some specimens it is of the usual shape,

in others it is strongly dilated, every intermediate form

existing between the two extremes. A type communi-

cated to me by M. Motschulsky, which I compared with

specimens from Northern China (described by me as C.

lateritia), was very dark-coloured beneath, and had the

mesosternum smaller than usual.

Mr. Lewis has not taken this insect; the specimens I

have seen came from Tsu Sima, a small island in the

Straits of Corea, to the west of Simono-saki, and were

found by Messrs. Bowring and A. Adams; the insects

from China and Japan have the black spots on the elytra

more fully developed than those from Siberia and Eastern

Europe.

Head slightly enlarged in the é, smooth and shining, a

broad space between the eyes slightly depressed ; its sur-

face, together with the lower portion of the face itself,

faintly wrinkled; eyes large, very slightly prominent,

feebly notched within, surrounded by a sunken orbit, the

surface of which is distinctly but not deeply punctured,

and sparingly clothed with white hairs. Antenne with

the four lower joints fulvous, more or less stained with

Genus CopTrocEPHALA, Lac.

Mon. Phyt. ii. 345.

The two species below both have in the male very large

heads and prominent eyes; Lacordaire has separated the

first, C. pallens, and formed it into his sub-genus Physau-

chenia ; had he seen the typical form of the insect, which

closely resembles in pattern all the other species of Copto-

cephala, he probably would not have done so; the charac-

ters given by him for the sub-genus are very slight and

unsatisfactory; the second species is now described for the

first time, and is at present confined to the Japanese

Islands.

somewhat closely punctured; a narrow line on the inner

half of the basal margin, a humeral patch and a short

transverse band just beyond the middle of each elytron (this

latter often interrupted) black. Legs entirely black.

This species closely resembles C. floralis; it may be

known by its entirely black legs, by the larger head in the ¢,

and also by the absence of the punctures on the face,

visible in the former insect.

oblong punctures ; on either side the medial line is a broad

black vitta, which extends from the base very nearly to

the apical margin of the thorax ; its inner edge is broadly

but slightly, emarginate ; placed ina triangle on the middle

of the space between this vitta and the lateral margin are

three small black spots, the innermost being usually con-

fluent with the vitta. Scutellum narrowly triangular,

smooth and shining. Elytra scarcely broader than the

base of the thorax, parallel; sides slightly lobed at the

base ; above convex, thickened in the immediate neigh-

bourhood of the scutellum; distinctly and somewhat

closely punctured, the punctures indistinctly arranged in

striz at the base, irregularly scattered over the rest of the

viated just before reaching the apex, and four large spots

black; the latter are arranged as follows: two oblong,

placed below the base, the first half-way between the suture

and the humeral callus, the second on the callus itself, and

two placed transversely below the middle, one sublinear,

near the suture, the other larger and irregularly ovate,

half-way between the suture and outer margin. In some

specimens these patches are larger, and the inner one of

the second row is confluent with the sutural line. The

V. On some new species of Butterflies discovered in Extra-

Tropical Southern Africa. By Rotanp TRIMEN,

F.L.S., &c.

[Read 2nd December, 1872. ]

In the paper which I have now the pleasure of submitting

to the Entomological Society there will be found descrip-

tions of fourteen new species of Rhopalocera, viz.—three

Satyrine, two Nymphaline, five Lycenide, and four

Hesperide. In the first-named sub-family, Mycalesis

perspicua is interesting as belonging rather to the Asiatic

than to the African section of the genus. The Mympha-

line afford two striking instances of ‘‘ mimicry ;” the one

of a Danais by a Diadema, the other of an Acrea by a

Pseudacrea. Among the five Lycenide, the little Aph-

neus pseudo-zeritis is remarkable for combining the

colouring and ornamentation of two nearly-allied genera,

and Liptena Aslanya is a noteworthy addition to a very

aberrant group, hitherto only known as characteristic of

Tropical Western Africa. Two of the Hesperide present

characters of interest, Cyclopides Meninx being not dis-

tantly allied to the South American C. Menes, Cramer,

and C.. Barbere possessing under-surface markings very

dissimilar from those of its congeners.

For a knowledge of these welcome additions to entomo-

logical science, | am indebted to many of the friends

whose valued assistance enabled me to record somany new

species and facts in Rhopalocera Africe Australis and

papers subsequently published, as well as to others with

whose work I have more recently been so fortunate as to

be made acquainted. Among the latter I should specially

mention Mr. Walter Morant and Mr. H. C. Harford, who

not long since resided in Natal, and who, in addition to

collecting insects with remarkable zeal and success, kept

careful records and drawings of their discoveries. Dr.

Seaman, Secretary to the Natural History Association of

Natal, has been similarly zealous in the cause, and I trust

shortly to communicate to the Entomological Society his

and Mr. Harford’s very valuable accounts of the larvee

and pupe of many Natalian butterflies.

Genus Lepronevra, Wallengren.

Leptoneura Dingana, n. sp. (Pl. I. fig. 1.)

Exp. 2 in. 1 lin.

Dark brown. Forewing: beyond middle a curved

macular fulvous-ochreous band between sub-costal ner-

vure and 2nd median nervule, the three upper spots united

and forming a sub-apical bar; contiguous to outer edge

of bar, a compound black ocellus tripupillate with bluish-

white. Hindwing: a sub-marginal row of 5 unipupillate

black ocelli in strongly-marked, fulvous-ochreous rings,

of which the Ist is between the sub-costal nervules, and

the 5th between 2nd and 1st median nervules; an indis-

tinct and minute 6th ocellus close to anal angle. UNDER-

sIDE.—Dull fuscous brown, with very indistinct mark-

ings. Forewing: only a faint trace of fulvous band ;

compound ocellus smaller than above, ill-defined, but the

three pupils conspicuous. /indwing: the 6 ocelli present,

but without fulvous rings; before them indistinct traces

of an irregular transverse streak, darker than ground-

colour; beyond them two indistinct, parallel, hind-mar-

ginal dark streaks.

This species exhibits unmistakable affinity to L. Bowkeri,

Trimen ( Trans. Ent. Soc. Lond., 1870, p. 347, pl. vi.

f. 2), but is readily recognized by the fulvous band and

very much larger compound ocellus of the forewings ; the

whole ground-colour is also more rufous than that of

Bowkeri, and the underside markings much more obscure.

It should be noted, however, that the 2 of Bowheri

remains unknown, and that the differences presented by

the only known specimen of LZ. Dingana (the sex of which

I have been unable to determine) are not greater than

may be observed between the sexes of other Satyride.

The example described was taken by Mr. Walter Morant,

at Malang Spruit, between the Movi and Bushman’s

Rivers, in October, 1868 ; it flew low, and settled on rocks

and on the ground, with the wings open.

Hixp.(¢ )lim. 5 liny;: (6.), Vim: 6lin:

Pale greyish-brown. Forewing: a fulvous patch occu-

pies discotdal cell, not rising above it, but extending beyond

it and over median nervules to about their middle, as well as

below median nervure and its 1st nervule, but not reaching

sub-median nervure or quite to base ; touching extremity

of upper portion of patch, a bipupillate black ocellus in

a pale yellowish-grey ring; costal margin indistinctly

hatched with greyish-yellow from base to beyond middle.

FHlindwing without markings. UNpDERsIbE.—Hindwing

and costal and apical region, with hind margin of fore-

wing irrorated with greyish-yellow. Forewing: fulvous

patch slightly smaller than on upperside ; ring of ocellus

paler, more distinct. Hindwing: beyond middle a sub-

marginal row of 8 ill defined greyish-yellow spots; pre-

ceding 4th spot, and between it and extremity of discoidal

cell, a similar spot; an indistinct similar spot near base,

between median and sub-median nervures; two smaller

ones on edge of cell, marking origins of radial and 2nd

sub-costal nervules; and 2 or 3 small ones on costa before

middle. In both wings, on hind-marginal edge, a row of

small, inter-nervular, greyish-yellow spots, more apparent

in hindwing than in forewing.

The sexes do not differ, except that the irrorations and

spots of the underside of the wings are more conspicuous

in the ¢.

This species stands nearer to EL. Hyperbius, Linn.;

than to any other South African Erebia; but it differs

from the latter in its much paler colouring throughout,

its total want of any ocelli or fulvous colouring on the

upperside of the hindwings (in which respect it is like

i. Naryria, Wallengren), its hatching of greyish-yellow -

on the upperside of the costa of the forewings, its much

yellower and more distinct underside hatching and irrora-

tion, and its want of the two transverse ferruginous striz

on the underside of the hindwings.

Mr. J. H. Bowker discovered a ¢ of this butterfly in

the Zwaarte Ruggens, division of Uitenhage, in the month

of August, 1870; and, quite recently (July, 1872),

forwarded a g captured on the road from Bethulie to

Burghersdorp, on the Colonial side of the Orange River.

These are the only examples that I have seen.

Pale brown, with very clearly marked, white-pupillate,

black ocelli in yellow-ochreous rings ; common to both

wings, a slightly paler shade of ground-colour beyond an

indistinct line about middle, and three parallel, hind-

marginal, dark lines, of which the outermost is on the edge

next tocilia. Forewing: a small ocellus between radials; a

large one on 2nd and 1st median nervules, its ring extending

above and below those nervules respectively. Hindwing: 2

good-sized ocelli between 3rd and Ist median nervules; a

small one above 3rd median nervule; occasionally, a

minute indistinct ocellus near anal angle. UNDERSIDE.—

Pale greyish-ochreous, closely hatched and trrorated with

brown ; two reddish-brown transverse lines, one before,

the other beyond middle; the outer line immediately

succeeded by a conspicuous pale yellow stripe, externally

ill-defined ; hind-marginal streaks well-marked; all the

ocelli in well-marked rufous-brown rings encircling the

yellow-ochreous rings. Forewing: the two ocelli answer

to those on upperside. Hindwing: 7 ocelli in sub-marginal

row, of which the 4th and Sth (between 3rd and Ist

median nervules) are considerably larger than the rest,

the three above them small (about equal in size), and the

7th (at anal angle) much the smallest, but clearly defined.

A g taken at St. Lucia Bay by the late Colonel Tower

has all the ocelli on the underside of the wings indistinctly

marked, and much smaller than usual; the yellow stripe

beyond middle deeper in tint; and the transverse line

before middle immediately preceded by some yellow

clouding.

The close brown lines or hatchings and conspicuous

pale yellow stripe of the underside readily distinguish this

butterfly from IM. venus, Upfr., apart from its much

paler colouring on the upperside. Its nearest allies are

M. Meneris, Linn., and M. Ostrea, Westw. (= Otrea,

Hiibn. nee Cram.) ; but it differs from the former by the

much broader stripe of the underside, and from both

by the number (3) and distinctness of the ocelli on the

upperside of the hindwings.

I first met with this Mycalests (which seems nearer to

the Chinese and Indian species just mentioned than to

any of its African congeners) at Port Natal, where I took

a single ¢ specimen on the 3rd August, flitting about

long grass in some rough ground at the base of the Botanic

Garden, near D’Urban. On the 4th March, 1867, I

again met with the species, capturing one of each sex

among grass at the bottom of a deep ravine at the Mapu-

mulo Mission Station, between the Umvoti and Tugela

Rivers, in Natal. During the same year the @ variety

above mentioned was taken at St. Lucia Bay, and Mr. H.

C. Harford has since forwarded me a ¢ captured on the

29th January, 1869, “ among long grass by a river side,”

near Pinetown, in Natal. ‘These five examples are the

only ones which have come under my notice.

the latter nervule); a narrow sub-apical stripe of 3 spots,

extending from a little below costa to 3rd median nervule

similar one near anal angle, just above sub-median nervure.

Hindwing: in basal region a large, sub-rotundate patch,

This Diadema is one of the puzzling series “of ver y

closely allied forms that includes D. Anthedon, Doubl.,

D. dubia, De Beauv., D. mima, mihi, ete. It completes

the list of striking mimetic analogies between the known

African Danaides and Diademe, by presenting an un-

mistakeable mimicry of Danais Ochlea, Boisd., a local

species inhabiting the coast of Natal and St. Lucia Bay.

All the white markings i in the Diadema are in proportion

smaller than in the Danais, and the central bar of the

forewings is more obliquely placed ; while on the under-

side the erey colouring is paler, and the hindwings want

the narrow basal black of Ochlea, and present a pale ray

(from the central patch to the apex) which is not found

in the latter.

D. deceptor is intermediate in character between D.

mima and D. Anthedon, but is on the whole nearer to

the former, both in size and markings; though the ab-

sence of any ochreous tinge in the white bars and the

pinkish gloss of those markings, added to the width of the

central bar of the forewings, approximate the insect to the

latter.* The white spots of the head, palpi, and back of

thorax, are identical in the three species, and a tuft of

ochreous hairs on the posterior region of the breast is also

found in all of them.t

The only example of this interesting Diadema known

to me was taken by Mr. W. Morant, in a road cut

through thick bush, about the middle of July. In reply

to an inquiry from me, that gentleman states that the

place of capture was one in which he had sometimes found

Danais Ochlea.

* In the South African Museum there is an unusually small ¢ Dia-

dema mima (exp. al. 3 wne.) which was received from Natal, and which

presents several characters tending in the direction of D. deceptor. All

the pale markings of the forewings are proportionately larger than usual,

and the patch of the hindwings is white, with an ochreous edging only.

On the underside the colouring is that of D. mima, but there is a very

faint trace of the pale ray which distinguishes D. deceptor.

{+ With regard to the intimate affinity so apparent among the mimicking

African Diademe, I wish to place on record that D. mima, ¢, and D.

Anthedon, 9, were taken in copuld by Mr. H. C. Harford, in a wood on

the Little Umblanga River, in Natal. On the receipt of the specimens so

captured, I at first imagined that Mima and Anthedon would turn out to

be the constant sexes of one species ; but having subsequently examined

with care all the specimens to which I have had access, I find that both

sexes of each form exist. Of Jima I have determined (from a comparison

of the fore-legs with those of the sexes of D. Misippus) 11 gs and 5 Qs,

and of Anthedon (in the same manner) 14 ¢sand6@s. On examining

the West African D. dubia and D. Anthedon in the British Museum, I

found in like manner 2 ¢s and a 9 of each form. The case of the

African Diademe of this section (Huralia, Doubl.) is a very remarkable

one; for, unstable as their pseudo-specific characters would appear to be,

they are unstable only in the direction of mimicking the peculiar Dana-

ides (sect. Amauris, Hibn.) inhabiting the same regions, following and

reproducing even the slightest variations presented by the latter butterflies.

Tt is scarcely possible to doubt that these Diademe@ are divergent forms of

one parent species ; and, looking to their present paucity of numbers, and

to their apparent dependence for very existence on closely copying every

form presented by the abundant Danaides, the idea suggests itself that

some advantage to them might result from such an instability of type

as that to which unions between such different forms as Mima and An-

thedon would in all probability lead.

The only specimens which I have seen both appear

to be of the female sex, the fresher and more perfect

of the two having the bands much more decidedly

tinged with yellow than the other. The species is nearly

allied to P. Hirce, Drury, judging from a comparison of

the two specimens with Mr. Hewitson’s figure of the

typical form of the @ Hirce (Eurytus, Clerck) from

Calabar.* It may, however, be readily distinguished

from the latter by the absence in the forewings of the con-

spicuous white band which in the 2 Hirce extends from

the inner-margin towards the sub-apical band; and by

the fuscous base of the hindwings, which in the 2 FHirce

is occupied by the white of the band. In P. cmitator the

sub-apical band of the forewings is much longer and nar-

rower, and the 2nd and 3rd cellular spots are in all the

wings nearer to the base.

Mr. H. C. Harford, now of H.M. 99th Regiment, took

a single specimen, on the 21st January, 1868, in a narrow

bush-path near the Little Umblanga, and describes it as

settled on the ground, with the wings expanded, sucking

moisture from the damp sand. The only other example

known to me was captured by Mr. Walter Morant, on

the 8th June, 1869, near Pinetown: it is noted by him as

flying near the ground on a hillside in the vicinity of

thick bush. Mr. Harford observes that these two indi-

viduals were the only ones ever seen by him.

P. imitator is a close mimicker of Acrea Aganice,

Hewitson, 2, ¢ differing principally in the forewings, in

the minor features of possessing some black spots near the

base, and a slight inner-marginal whitish suffusion, and of

wanting a separate white spot at the extremity of the sub-

apical bar. The spots at the base of the hindwings are

not so numerous as in the Acrea; and the palpi are yel-

low, instead of black spotted with white. The spotting of

the head, thorax, and base of abdomen, is almost identical

in the two insects ; and in both the abdomen is ochreous

on the underside, while the ochreous abdominal spots and

oblique, apical streak is formed by the confluence of the

first spots of the two rows; cellular region and costa ad-

jacent suffused with fulvous-yellow from base; between

median nervure and inner margin an irregular, elongate,

fuscous marking. Hindwing: spots arranged similarly to

those in forewing, but more suffused and indistinct, espe-

cially in basal region and beyond middle towards lower

part of hind margin, where there is a clouding of brownish-

fuscous; anal-angular fulvous-ochreous spot smaller than

on upperside, and edged inferiorly with black.

This curious little species appears to constitute a passage

between the genera Aphneus and Zeritis ; the upperside

of the wings, with a blue gloss’ and fulvous anal-angular

spot (but without the usual yellow-ochreous markings),

resembling that prevalent in the former genus, while the

metallic-centred spots of the underside are so similar in

arrangement and appearance to the characteristic spotting

of Zeritis (and particularly to that of the little Z. Phosphor,

mihi) that, until I detected the remains of a second tail on

each hindwing, I was strongly disposed to place the butter-

fly in the latter genus.

I am indebted to Miss Fanny Bowker, of Pembroke, near

King William’s Town, for the only specimen that I have

seen; it was taken by her on a low shrub (a species of

Euclea), on the border. of a wood at Tharfield, in the

between small rounded spot and apex, and 4 in a row from

apex along hind-margin as far as 3rd median nervule, the

lowest spot the largest; orange-fulvous replaced by a broad

creamy band along inner margin; inner portion of hind-

marginal border below apical region marked with a row

of 3 good-sized blackish spots. Hindwing: on basal lobe

of costa a rather large subovate spot; beyond it, below

costal nervure, 2 similar spots placed longitudinally; a

small spot in discoidal cell close to base, followed by a dot;

a very irregular, roughly V-shaped marking at extremity

of cell; between this marking and inner margin are a

similar but more elongate marking, and a rather small

sub-ovate spot; beyond middle a very irregular transverse

row of 8 spots of various sizes and shapes, of which the

2nd and 4th (of about equal size) are much larger than

the rest; a hind-marginal row of 9 spots, of which the 3

last form an oblique line to inner margin beyond middle;

at anal angle a small, short, oblique, red mark, bordered

on each side with white; quite at base, below origin of

sub-median nervure, a small round spot like the rest.

Forewings with hind-marginal outline strongly elbowed

about extremity of radial nervures: hindwings with a slight

anal-angular lobe, and two tails of moderate length, broad

at the base and tapering gradually to a point at extremities

of 1st median nervule and sub-median nervure respectively.

lateral base of each palpus, and 6 spots on each side of

abdomen (the latter edged with black) silvery-white.

General colouring of body fuscous-ochreous, with two

longitudinal whitish stripes on each side of breast; legs

ochreous, with whitish femora.

A é example from Murraysburgh differs from other

specimens in the great breadth of the fuscous bordering,

particularly in the forewings.

There is a series of variations which leads from Z.

Malagrida, Wlgrn., in the direction of Z. Argyraspis,

but the latter, which is the largest and finest form I have

seen, appears to be the only one sufficiently well-marked

in both sexes to admit of separation as a species. From

the type Z. Malagrida (to which M. Wallengren, who

has seen specimens which I have forwarded to him, informs

me must be referred the “ var. Aglaspis” of Rhop. Afr.

Austr., li. p. 272), Z. Argyraspis seems to be constantly

distinguished by the very broad field of orange-fulvous,

which extends to the costal edge of forewings on the upper-

side, and by the much brighter, more clearly defined, and

rounder silvery spots of the underside. As regards the

latter, it is very noticeable that the spots of the hind-mar-

ginal row in the hindwings are not saggitate, and that

those of the row beyond the middle are fur more trregu-

larly placed than in Malagrida, and present no approach

to the continuity which almost forms a stripe in that

species. In addition to these distinctions should be men-

tioned the much larger size of Argyraspis, and the

different outline of the wings, which latter consists in a

marked prominence of the apical region of the forewings,

and the production of the slight prominences in the hind-

wings of Mulagrida at the ends of the sub-median nervure

and 1st median nervule into distinct pointed tails.

Dr. Kannemeyer was the first to communicate to me

this striking form, in the. shape of a ¢ taken near

upperside ; mark at extremity of cell broader, and preceded

by two similar cellular marks; ray from costal border

before middle prolonged, with an mward curve, to 2nd

at its extremity, to 1st median nervule; cellular grey

marks indistinctly prolonged below median nervure ; costal

spots of the ground colour distinct; apical grey border

intersected by 2 macular streaks of the ground colour from

costal edge, joining the ground colour at. their lower ex-

tremity ; the outer of these rows is the longer, composed of

more lunulate spots, and situated immediately before. the

hind-marginal narrow grey edging. Hindwing: reddish-

ochreous spots arranged in five transverse rows at about

equal distances apart, viz.: the Ist, near base, of 5 minute

elongated spots; the 2nd, before middle, of 5 or 6 linear,

more or less united spots; the 3rd, about middle, con-

a broad yellow bar, and the hindwings being red, with a

few black spots, and a grey hind-marginal border.

The only specimen of L. Aslanga that I have seen was

sent to me by Mr. W. Morant at the end of 1869, with a

note that it was taken near Pinetown by a resident there.

Mr. Morant at the same time wrote that he had himself

captured an example, on 19th May, 1869, in his garden

at that place, and that it flew far higher and more strongly

than Pentila tropicalis.

region of forewing mingled creamy and fulvous-ochreous,

the fulvous predominating in hindwing. Forewing: white

spots as above, but rather larger, and relieved by black

edgings from the ochreous colouring round them; a small

black spot on costa close to base ; a row of 7 small black

spots on hind margin from apex to anal angle, the lowest

two suffused and enlarged, so as to joi inner-marginal,

blackish ground colour. Hindwing: between costal and

sub-median nerv ures, two transverse white bands (one before,

the other beyond middle) edged on both sides with macular

black streaks ; a hind-marginal row of 6 small black spots ;

space between sub-median nervure and inner-marginal edge

blackish, irrorated interiorly with creamy-cchreous : ; costa

at base with a black curved mark, about and beyond middle

bordered with grey.

2 Not so dark as & ; spotting similar, but all the yellow-

ochreous spots larger and more distinct; cilia creamy

instead of white, more broadly varied with black. UNDER-

sipE.—As in 6, but the fulvous brighter, especially in

hindwing.

This is a species so closely allied to P. Mohozutza,

Waller., that in 1865, on receiving a single 2 from Mr.

Tl, Bowker, I inclined to the belief that it was only an

unusually large example of that insect. But an inspec-

tion of both sexes, kindly presented to me by Mrs. Barber

and Mr. Schiffman in 1868, has convinced me of the dis-

tinctness of P. Chaca. Apart from the very considerable

difference in size (P. Mahozutza not exceeding about 13

lines), both sexes of P. Chaca may, as regards the mark-

ings of the upperside, be recognized by the possession of

two small additional white spots (the 4th and 5th) in the

transverse row beyond the middle of the forewings, and

the duller and proportionally much smaller ochreous spots

of the hind-marginal row in the forewings of both sexes and

in the hindwings of the 2. On the upperside of the hind-

wings of the & Chaca there are, however, an indistinct

central spot, and traces of 3 hind-marginal spots not found

in the ¢ Mahozutza. The mdetidcd in both sexes differs

from that of Mahozutza by being paler; by having a row

of distinct black spots, instead of a black streak, along the

hind-marginal edge of the wings; and by presenting a

whitish transverse band before the middle in the hind-

wings.

Mr. Bowker took this butter fly in several localities near

120 Mr. Roland Trimen on

the Tsomo River, Kaffraria, in December, and notes it as

occurring in “open grassy glades between forests upon

high mountains, sitting on flowers with closed wings.”

Mrs. Barber, however, who met with the species near

Bathurst in March, 1870, writes, that it frequented ‘ long

grass, in rather a low and damp locality, among trees.”

Mr. Schiffman’s specimens were captured on one of the

hills round Grahamstown, but I am not aware in wha

kind of station. Me

tremity of discoidal cell; beyond middle a very irregular

row of 8 spots, of which the first 3 touch each other, and

form a short costal and sub-apical stripe, the 4th and 5th

(nearest hind margin) are small and indistinct, and the 7th,

a small whitish spot immediately above disco-cellular spot ;

5 minute white marks on costal edge, of which the 4th ad-

joins first 3 spots of transverse row; 4th and 5th spots of

transverse row merged in an oblique apical marking of

hoary-grey. Hindwing: an elongate white mark in dis-

coidal cell before middle is scarcely separated from a large

irregular white marking occupying extremity of cell, and

extending to a hoary-grey hind-marginal suffusion ; this

marking is joined, at its upper portion, by an oblique white

stripe from costa about middle ; between median and sub-

median nervures an ill-defined longitudinal white stripe,

extending from near base to join hind-marginal, hoary-grey

near anal angle.

The palpi and abdomen are wanting in the single speci-

men from which the above description has been made.

From the form of the wings I am disposed to think it a ?

example.

Butterflies of Southern Africa. 121

This species is at once distinguished from all its con-

geners in South Africa by the remarkable disposition of

the white markings of its underside, which indeed are un-

like those presented by any member of the Hesperide that

I can call to mind.

I have named this curious butterfly in honour of my

friend Mrs. Barber, of Highlands, near Grahamstown,

whose kind and valuable aid in working out the Rhopa-

locerous fauna I have had such frequent occasion to ac-

knowledge in previous papers. The single specimen

described was taken by Mrs. Barber in October, 1871,

‘‘among long grass and rushes near water” in the Storm-

bergen, a range of mountains forming the boundary be-

tween the Queenstown and Albert Divisions.

Exp. 104 lin.

$ Dull brown, without markings. UNDERSIDE.—

Forewing : on hind-marginal edge a row of 4 small, tri-

angular, inter-nervular, yellow spots between apex and

3rd median nervule, diminishing in size from the apical

spot. Hindwing : a row of 6 similar, larger spots on hind-

marginal edge, the Ist (at apex) linear, the last just

above sub-median nervure; two broad, white, longitudinal

stripes, one commencing abruptly in discoidal cell near ex-

tremity, and joining 3rd spot on hind margin; the other

running from base between median and sub-median ner-

vures, and ending suffusedly before 6th spot; a narrow

white edging to inner margin.

This species is allied to C. Menes, Cramer (Pap. Exot.

t. cccxciil. ff. H. 1), but is at once recognized by its want

of the conspicuous apical yellow streaks on. upperside of

the forewings, and by its possession of two white stripes

on underside of the hindwings.* Menes is a native of

Tropical South America, though Cramer gives for it the

* Stoll’s figure of C. Menes (Suppl. Cram., t. vii., f. 6 G) represents the

subcostal nervure of forewings coloured ochreous-yellow from the base

almost to the middle. This character is also prominent in € (Ancy-

lorypha) gracilis, Felder, from New Granada, which may be identical

with Stoll’s insect, though the underside of its hindwings is conspicuously

clouded with ochrey-whitish. Vide ‘‘ Reise der Novara,” Lep. iii., p. 520,

Above, the head, palpi, patagia and pterygodes ferru-

ginous-ochreous ; back of thorax and of abdomen dark

purplish-brown, the former having posteriorly some yellow

hairs, and the latter the segmental incisions, and a terminal

tuft, fulvous-yellow. Beneath, the palpi, breast and legs

(with abdomen near base) yellow, tinged with ferruginous-

ochreous ;' median line and terminal portion of abdomen

spots being on each side of median line. Antennze black

throughout; the clubs not recurved at tip, but slightly

bent outwards.

Near P. Herilus, Hpfr.,* but easily recognized by the

fewer and differently situated black spots of the underside

of the hindwings; and further differmg from that species

in the ferruginous colouring of the underside, and in .

wanting the yellow cellular spot and conspicuous longi-

tudinal sub-inner-marginal stripe on upperside of hind-

wings. Morantii is besides much larger than Hertlus.

A species from Celebes, P. flavescens, Felder,} presents

almost the same spotting as Morantii on the underside of

the hindwings, but has the spot nearest base above the

sub-costal nervure, and possesses an additional spot just

beyond that spot.

I have named this species after Mr. Walter Morant,

who has been a most successful collector and careful ob-

server of South African Lepidoptera. Mr. Morant informs

me that the single specimen from which the above descrip-

tion is made was taken sitting on a shrub at the edge of a

small wood, on the 30th June, 1869.

VI. On the Hydroptilide, a Family of the Trichoptera.

By the Rev. A. E. Eaton, M.A.

[Read 3rd February, 1873. ]

Trichoptera in general, but more especially the Hydropti-

lide, are an annoyance to the Lepidopterist. If he lives

near a river they are a constant source of disappointment to

him whenever, on a summer evening, he inspects the ento-

mological miscellany which accumulates upon his table-

cloth beneath the gashght Down falls a scorched and

crippled “ Micro—”; he has the trouble of looking at it;

but his first glance “detects the scabrous clothing of the

anterior wings of a Micro-Trichopteron, whose hair looks

as if it had been brushed the wrong way, in lieu of the

scales of a Micro-Lepidopteron; and his only consolation

is that he may leave the pinning of that kind of things to

the Trichopterists.

A. great similarity of ornamentation prevails amongst

congeneric species of the Hydroptilide ; and the density

of their hair prevents structures of dried specimens from

being made out with certainty, besides concealing the

neuration of the wings completely. Consequently | most

entomologists have been deterred from the study of this

family of insects, and little is known about them. Up to

the present time only two genera have been defined, and

fourteen or fifteen species. “Of these one species is fossil,

seven or eight are European, and the rest are from Ma-

deira, North America, Ceylon and New Zealand. In

addition to these I have been able to determine four

genera and six species, of which species five are British.

Mr. M‘Lachlan most kindly sent all of his specimens

of Hydroptilide to me, with permission to subject them

to most ruthless treatment. This has enabled me to effect

some reductions in synonymy, and to verify some points

in their geographical distribution. I have also examined

Stephens’ and Wollaston’s collections in the British

Museum,

TRANS. ENT. SOC. 1873.—PART Il. (MAY.)

126 Rev. A. E. Eaton on

The synonymy of species collated from foreign authors

may be taken at what it may be worth. Without inspec-

tion of type-specimens it is impossible to arrive at decisions

absolutely trustworthy respecting the species to which de-

scriptions were intended to apply. All other identifications

(since no figures of appendices have been published hitherto)

are mere tentative conjectures more or less probable. Still,

where they cannot be disproved, there is no reason why

they should not be accepted. However, it is well not to

attach much importance to them. At the least they may

be regarded as indications of the occurrence abroad of

species very nearly related to our native forms. Some of

the British species have a wide range, being found even in

Italy. Itis possible, therefore, that Pictet’s and Kolenati’s

‘species really occur in Great Britain. And, therefore,

though unable to affirm this to be the case, I admit the

identifications which have been set forth by previous

workers in hope that they may be verified; but I do not

give localities for species (without my having seen speci-

mens from them) on the strength of these provisional iden-

tifications.

In Dr. Hagen’s “ Phryganidarum Synopsis Synonymica”

a complete index to the literature published before the year

1864 relating to the family already exists. Up to that

date I shall therefore give merely an enumeration of the

authors with references to figures only. The places of

descriptions may be ascertained from the subjoined list of

publications. Since 1864, very little has been published

about the Hydroptilide, and, in consequence, few addi-

tions require to be made to Dr. Hagen’s index; such as

there are I give in detail. There are some changes in the

synonymy which I have adopted from Mr. M*‘Lachlan’s

** Monograph of the British Trichoptera ;” for others I am

myself responsible.

Family HYDROPTILID &.

Antenne shorter than the wings, much shorter in the

female than in the male; their basal joints not, much

stouter than the others. Ocelli present or absent. Maxil-

lary palpi alike in both sexes, slender, sparsely hairy, five-

jointed, but often apparently four-jointed owing to the

obsolescence of the first jot. Labial palpi with the ter-

minal joint enlarged. ‘Tubercles of head and thorax with

long. coarse stiff hairs. Wings narrow, with very long

fringes; the anterior with numerous erect or ascending

hairs on the disk, and sometimes with an appendage near

the base of the post-costa; the posterior with adpressed

hairs on the disk, and without a fold. Legs slender, not

very long; the posterior tibiz more or less sétose, some-

times pinnately hairy; the anterior tibiz spurless, or with

one spur; the intermediate with two or three, and the pos-

terior with four spurs. Abdomen short: in the male there

is usually a horny process from the ventral antepenulti-

mate segment, the penis is long, and during life retracted;

in the female the antepenultimate segment beneath has

sometimes an indistinct prominence, the ovipositor during

life is retracted and is furnished with two tentacles at the

apex. I have not detected any sexual differences in the

palpi, the neuration of the wings, or the tibial spurs.

The species with which I am acquainted appear to shun

excessive heat. Prominent objects by the waterside, such

the Hydroptilide. 131

as tall plants and shrubs, palings and walls, present great

attractions to them, and so does light. They retire to rest

mostly amongst the grass and herbs, though crevices in

bark and the uneven surface of shaded walls are frequent

resorts of theirs during repose. Their vivacity is remark-

able. As soon as they alight upon the ground they rush

along helter-skelter with unusual impetuosity, flying off |

for a short flight from time to time whilst in full career,

or coming to a dead stop to rest awhile with antennz

ascending and slightly separated (as suddenly as Stenop-

socus immaculatus is in the habit of halting), and then

starting off hurry-skurry once more. In deep repose some

genera place their antennz in a different posture to that

which they assume in these short pauses. The species

inhabit rivers and lakes. Their localities are sometimes

confined to the neighbourhood of rapids in rivers.

The larva inhabits a portable case.

I am inclined to remove the Hydroptilide from the

position usually assigned to them between the Sericosto-

mide and the Leptoceride, and to place them beside the

Rhyacophilide. The structure of the head and of the

ovipositor, the horny ventral process of the antepenulti-

mate segment of the male and its rudiment in the female

of nearly all the genera, and the presence in some genera

of an appendage to the anterior wing near the base of the

post-costa, are the chief points in the i imago which appear

to indicate affinity between these two families.

But it may be objected to this view that the Hydropti-

lide are ranked with the Inequipalpide, whereas the

Rhyacophilide are amongst the Aiquipalpide. So far,

however, as I have been able to ascertain, the maxillary

palpi of the male are five-jomted in the Hydroptilide, as

Pictet stated. The fifth jomt can be demonstrated with

a Codrington lens without much difficulty in the male of

Agraylea, and even in Phrixocoma under favourable cir-

cumstances. But if a 3 object glass and a compound

microscope be brought to hear upon specimens immersed

in fluid, the palpus is seen to be obviously five-jointed in

both sexes in all the genera, although in specimens freshly

killed and viewed in air it may have seemed to consist of

only four joints. And so the Hydroptilide being a family

of the quipalpide this objection is disposed of; and I am

not aware of any remaining to be raised against the pro-

posal to rank them close beside the Rh: yacophilide.

Since this was written I showed my figures to Mr.

132 Rev. A. E. Eaton on

M‘Lachlan. When he saw a drawing of the maxillary

palpus of Phrixocoma sparsa 4, he remarked at once its

likeness to the palpus of Rhyacophila.

Besides the mouth organs, the appendices of the male

are seen with advantage in fluid.

For the investigation of their neuration it is necessary

to denude the wings of their hair. This can be done with-

out difficulty if the wing detached from the thorax be laid

on a smooth sheet of paper and carefully brushed with a

fine camel’s hair pencil. The fringes may be left in siti,

as they do not interfere with the view, and they are not

easily removed.

Derivation.—( Gr.) Phrizxo-komes, with bristling hair.

Imago. Antenne in the male about half as long as

the wings, in the female a quarter as long ; stout, monili-

form, with coarse adpressed hair which gives to the joints

a somewhat scutiform outline, the basal joint longer and

thicker than the others; in repose laid together horizon-

tally, but during a halt in running slightly divergent and

ascending. Head and prothorax with coarse shaggy hair.

Ocelli absent. Maxillary palpi five-jointed, filiform, with

moderate, short, spreading pubescence ; the first two joints

very short, subequal; the third and fourth joints long, sub-

equal; fifth joint rather the longest. Labial palpi filiform,

with the apical joint as long as the other two together.

Wings lanceolate, acute: the anterior scabrous, with very

long fringes, in both sexes with a short appendage to the

inner margin near the base whence a fold is produced for-

the Hydroptilide. 133

wards; the discoidal cell open, the anterior branch of the

ramus discoidalis simple, the posterior forked with the an-

terior prong simple, the posterior prong forked; the superior

branch of the ramus thyrifer forked, the anterior prong

forked, the posterior prong simple; thus there are two

adjacent apical forks. The posterior wing with adpressed

hair and very long fringes, the costa shallowly concave in

the second third, and with one transverse veinlet; the

ramus discoidalis forked, the anterior prong simple, the

posterior prong forked; the ramus subdiscoidalis forked

with simple prongs ; thus there is one apical fork. Legs

of moderate length, the posterior tibize and the base of

the posterior tarsus strongly fringed externally ; anterior

tibia spurless, intermediate with two spurs, the posterior

with four. Abdomen with conspicuous appendices, which

vary in number with the species; penis setiform, retracted

during life, sometimes dilated at the tip; the horny pro-

cess of the male antepenultimate seement is enclosed by

long hairs from the segments.

I can add nothing at present to what has already been

published concerning the larva and its case, living as I do

in a neighbourhood unsuitable for their investigation.

The species affect rivers and lakes. ‘They occur

throughout Europe, from Sweden to Sicily, and from

Ireland to Attica; also in Canada and Texas.

edge of the disk and on the longitudinal nervures; these

are succeeded by the edging of the extreme tip of the

disk ; fringes black with a purplish gloss; posterior wings

black or dark gray. Legs testaceous with glossy hair, the

femora darker. Abdomen blackish; appendices superiores

stout, flattened, with the points turned in like a hooked

claw; during life when viewed in air they appear to be a

membraneous lobe above the penis (hence the name).

the Hydroptilide. 141

Female very similar, but with the markings of the wings

less distinct.

Length with closed wings ¢ ¢ 4 mm.

Hab.—The Sandy Brook, near Hanging Bridge, Ash-

bourne, Derbyshire. June. Does Hydroptila brunnei-

cornis, Pict. belong here? ‘The colour of the antennz is

similar, and the number of spurs is stated to be 0, 3, 4, by

Dr. Hagen in a letter from him to Mr. M‘Lachlan, he

having examined types.

Genus ORTHOTRICHIA, nov. gen.

Neuration, Pl. Il. 4 ¢,4a 2.

Hydroptila (part), M‘Lachlan, 1865.

Derivation.—(Gr.) Ortho-thriz, with hair upstanding

or on end. :

Imago. Antenne of the male about three-quarters as

long as the wings, filiform, the joints subcylindrical with

closely adpressed hairs, the basal joint rather larger than

the others: in repose divergent and ascending. Ocelli

absent. Maxillary palpi filiform, with moderate slightly

spreading hair, five-jointed; the first two joints very short,

equal; the next two joints subequal to one another; the

fifth joint a little the longest. Labial palpi filiform, with

the joints successively increasing slightly in length. Head

and prothorax with dense shaggy hair. Wings lmear

lanceolate, acuminate, with very long fringes; the anterior

scabrous, without an appendage to the post-costa, discoidal

cell open, the ramus discoidalis forked, with both prongs

forked; the superior branch of the ramus thyrifer forked,

the anterior prong forked, the posterior prong simple; thus

there are two forks before the apex and one behind it; the

posterior wings with adpressed hair, the costa shallowly

concave in its second third, and with one transverse

veinlet; the ramus discoidalis forked, with the anterior

prong simple, the posterior prong forked; the ramus sub-

discoidalis forked with simple prongs; thus there is one

fork before the apex. Legs of moderate length, the pos-

terior tibize and the base of the tarsus strongly fringed

externally; anterior tibia spurless, intermediate with three,

posterior with four spurs. Abdomen with small appendices

and setiform penis, the antepenultimate segment in the

male with a slender ventral lobe; after death the penis is

usually extruded.

The species inhabit warm rivers and lakes in England,

Madeira; also The Netherlands.

Orthotrichia angustella.

Pl. II. 4—4a, neuration 6 ?; III. 7—7c, genitalia ¢.

Hydroptila angustella, M‘Lachlan, 1865.

Head and prothorax with whitish or tow-coloured hair ;

palpi very pale testaceous; antennz pale fawn-colour,

sometimes with a very narrow whitish ring just before the

tip, at other times with three black rings separated by

whitish spaces, one ring near the tip, the others between

it and the middle. Anterior wings black, with glossy

pale tow-coloured markings, viz.: 3, the inner margin, an

indistinct fascia before the middle, which is preceded by

some faint streaks along the disk; after this is a large costal

spot subtended by an oblique longitudinal streak on the

disk which enters the terminal fringe and is itself sub-

tended by another shorter streak which reaches but does

not enter the fringe ; after this come two pairs of opposite

spots in the fringes, sometimes more or less confluent

across the disk; and last of all the extreme tip of the wing;

in the 2 the discal markings are very indistinct or absent,

the fringes (especially where the costal blotch should be)

and the indistinct fascia only are conspicuously pale. Pos-

terior wings gray. Legs very pale testaceous with glossy

hair. Abdomen yreen, with pale joinings, the bases of the

segments darker, each segment with a dorsal pair of dark

subquadrate or oval blotches; the appendices inferiores

slightly ascending, triangular, flat, and incurved; penis

exserted from an oval hump adpressed to one side of which

is an acute blade-like process curved upwards; there is a

setiform sheath, and the apex of the penis is thickened

and incised; in the female there is a slight apical projection

beneath the penultimate segment.

Length with closed wings ¢ 3°-—3°5, 2 4°5 mm.

Hab.—Standing water and slow streams in the south

of England; common at Ringwood along the bridges.

May, June, July. Bellagio, Lago di Como, August. The

Orthotrichia atra.

Hydroptila atra, Hag. 1865.

the Hydroptilide. 143

‘The head slightly inflated, with two rounded tubercles

close to the occiput. Antenne slightly more distant than

is usual in the species of this genus, stout, as long as the

body. Wings very narrow, pointed. Legs rather strong,

the posterior pair long. The colour is wholly of a uniform,

rather dark, blackish-brown; the wings brownish, with

brown pubescence, and with long grayish-brown fringes ;

the feet dark brown, with grayish hairs on the posterior

thighs. (The individual has lost its abdomen, but is other-

wise in good condition. )”

“* Madeira.” [After Hagen. |

The specimen is now in rather worse condition. Besides

the abdomen, it has lost its head, one antenna, and both

of its intermediate legs. ‘The joints of the antennz are

rather longer than is usual. The wings are as broad as

those of a Phrizocoma; the inner margin of the anterior

wing appears to be destitute of an appendage, and, ac-

cording to Dr. Hagen, the ocelli are wanting. A figure

of the neuration of the wings sent by him in a letter to

Mr. M‘Lachlan (from which I obtained information of the

want of ocelli), exhibits conformity to the neuration of

Orthotrichia angustella, excepting in the presence of a

cross-veinlet in the middle of the anterior wing. I am

inclined to consider this only a point of secondary import-

ance, having met with a similar specific difference of neura-

tion inthe genus Jthytrichia. ‘Therefore I have no doubt

that H. atra is referrible to Orthotrichia, because the

absence of ocelli, the form of the antennz and anterior

wings, and the neuration of the wings, do not admit of its

being otherwise disposed of.

Dr. Hagen, in his letter above alluded to, states that

a Madeiran species of Hydroptilide with ocelli was for-

merly present in Mr. Wollaston’s collection. ‘The only

specimen was of small size, and was lost by an accident in

the course of working.

Mr. M‘Lachlan possesses another specimen of an un-

described Orthotrichia from the same island. Being un-

able to figure the appendices I do not describe it.

Genus OXYETHIRA, nov. gen.

Neuration, Pl. II. 5; 5a, posterior wing.

Derivation.—(Gr.) Oxu-etheiros, with sharp-pointed

hair.

Imago. Antenne in the male half as long as the wings,

144 Rev. A. E. Eaton on

submoniliform, with sparse closely adpressed hair which

gives to the joints a subscutiform outline; the basal joint

rather larger than the others ; in repose they are approxi-

mated to each other and ascending. Head and prothorax

with dense shaggy hair. Ocelli present. Maxillary palpi

filiform, with moderate slightly spreading hair, five-jointed ;

the first two joints very minute, subequal; the third slightly

shorter than the fourth; the fifth slightly the longest.

Labial palpi with the first joint very short, the second not

so long as the third, which is oblong-ovate and slightly

compressed. Wings linear lanceolate, acuminate, with

very long fringes; the anterior scabrous, without an appen-

dage to the inner margin, the discoidal cell open; the

anterior branch of the ramus discoidalis simple, the pos-

terior branch forked with simple prongs: the superior

branch of the ramus thyrifer forked with simple prongs;

thus there is a primary fork before and behind the apex;

the posterior wings with the costa elbowed near the base,

and with adpressed hair; the ramus discoidalis simple;

the ramus subdiscoidalis forked with simple prongs; thus

there is one primary fork behind the apex; no transverse

veinlet. Legs of moderate length, the posterior with the

tibia and the base of the tarsus strongly fringed externally;

anterior tibia spurless, intermediate with three spurs, the

posterior with four. Abdomen with small appendices and

setiform penis; the horny ventral lobe of the antepenulti-

mate segment in the male very short.

The English species occurs in ponds. The genus is

represented in Great Britain, France, Germany (perhaps

Switzerland), Turkestan and New Zealand. The Turke-

stan and another species of doubtful locality are at present

undescribed, and are in Mr. M‘Lachlan’s collection; the

former being on loan from the Moscow Museum.

Oxyethira costalis.

Pl. II. 5, neuration ¢; 5 a, posterior wing; III. 8—8 a,

genitalia ¢.

Hydroptila costalis, Curt. 1834; H. tineoides, Steph.

1836; ? H. flavicornis, Pict. 1834.

Head and prothorax whitish-yellow (the colour of tow),

frons with some blackish hairs; palpi smoky white; an-

tenne pale fawn-colour throughout, sometimes with an

indistinct narrow ring before the tip dusky. Anterior

wings black, with glossy, tow-coloured markings, viz.: a

the Hydroptilide. 145

slender fascia before the middle which expands in both

fringes and is preceded by some indistinct clouds on the

disk; this is followed by a large triangular blotch extend-

ing from the costal fringes almost across the wing and

subtended by a pale dash in the terminal fringes; this is

followed by a small spot on the costa subtended by a

larger one on the terminal margin, both entering the

fringes; after these come the extreme tip, and a small

spot just before it in the terminal fringes; posterior

wings gray, with concolorous fringes. Legs testaceous,

with glossy hair. Abdomen pale oreenish, ai two dorsal

rows of pedunculated black spots; appendices superiores

stout, claw-shaped, with the points turned inwards; two

little tubercles on each side of the penis may represent

sheaths.

In the female the basal clouds on the anterior wing are

less distinct; the fascia is interrupted; and an oblong

blotch on the costa subtended by a spot on the disk, takes

the place of the triangular blotch. Antenne a quarter as

long as the wings.

Length with closed wings ¢ 3—3°5, 2 4 mm.

Hab.—Ponds in Woburn and Battlesden Parks, Bed-

fordshire, which are infested with Polygonum amphibium.

May, June, July. It occurs also in Scotland, and the

Département de l’ Aube, near Bar-sur- Seine (M‘Lachlan’s

collection); also at the end of May at Kénigsburg (Hag.

in letter to M‘Lach.), and in Brabant.

Oxyethira albiceps.

Hydroptila albiceps, M‘Lach. 1862.

Head and prothorax whitish-yellow, frons with some

blackish hairs; palpi grayish-testaceous; antenne pale

testaceous, with the tip dark gray; anterior wings grayish-

fuscous; the inner margin towards the base, and a very

indistinct fascia before the middle which expands in the

fringes of the inner margin and is extended along it for a

little distance as a narrow streak which lies partly in the

fringes and partly in the contiguous portion of the disk

where it is interrupted by a dark spot on the longitudinal

fold, paler; there are also a pair of opposite spots and

some discal streaks in the terminal region of the wing,

and also a transverse blotch forming a fascia immediately

before the dark apex of the wing , paler. Posterior wings

146 Rev. A. E. Eaton on

pale gray. Anterior legs gray, with pale joinings to the

tarsi; posterior legs testaceous. Abdomen (wanting in Mr.

M‘Lachlan’s specimen “ brown above, silvery beneath.”

Long. ¢ 2 mm.

Hab.—New Zealand.

Mr. M‘Lachlan thinks that the dark extreme apex of

the anterior wing was wanting in the type; hence the

discrepancy between my description and his.

Genus AGRAYLEA.

Neuration, Pl. II. 6.

Agraylea, Curt. 1834; Hydroptila (part), Zet. 1840;

Hydrorchestria, Kolen. 1848; Agraules, Walk. 1852.

Imago. Antenne of the male about three-quarters as

long as the wings, in the female about half as long, fili-

form; the joints loosely articulated, with adpressed hair,

the basal joint rather the largest ; in repose divergent and

ascending. Head and prothorax with long, coarse, shage

hair; ocelli present; maxillary palpi five-jointed, filiform,

with sparse spreading pubescence ; the first two joints very

short, subequal, the next two subequal and of moderate

length, the fifth joint rather the longest. Labial palpi with

the apical joint a little longer than the first two joints, and

hardly at all broader than thick. Anterior wings sub-

trapezoid or narrowly oblong, with a small appendage to

the inner edge near the base, the apex rather obtuse, the

disk scabrous, long fringes, and the discoidal cell open;

the anterior branch of the ramus discoidalis forked near

its origin, with simple prongs, the posterior branch forked

near its middle, with simple prongs; the superior branch

of the ramus thyrifer forked, with the anterior prong

forked, the posterior prong simple; thus there are two

forks before the apex and one behind. Posterior wings

ovato-lanceolate acute, the costa entire, hair adpressed,

fringes very long, no transverse veinlet; the ramus dis-

coidalis forked, with the anterior prong simple, the pos-

terior prong forked; the ramus subdiscoidalis forked,

with the anterior prong forked, the posterior prong simple;

thus there is a fork on either side of the apex. Legs o

moderate length, the posterior tibia with sparse short hair,

not fringed; anterior tibia spurless, the intermediate with

three spurs, the posterior with four. Abdomen with stout

short appendices and setiform penis, which is concealed

the Hydroptilide. 147

during life; the horny lobe from the antepenultimate seg-

ment beneath is rather long.

Species occur throughout Europe and in Turkestan.

The Turkestan species in Mr. M‘Lachlan’s possession,

sent from the Moscow Museum, is undescribed.

fHydrorchestria argyricola? multipunctata and sexma-

culata, Kolen. 1848; Agraules multipunctata and sex-

maculata, Walk. 1852.

Head and prothorax with pale yellowish-gray hair;

palpi pale; antennze black. Anterior wings usually with

pale-yellowish markings; these are sometimes,—on the

inner margin a long space near the base followed by two

shorter ones, of which one is near the middle, the other

near the arculus, very conspicuous; on the terminal

margin two or three small spots, the first two of which

enter the fringes; on the costal margin a conspicuous

blotch at the pterostigmatic region, followed by two

minute spots towards the tip; the disk has many spots,

often there are three larger than the rest m the middle of

the post-median portion of the wing. Posterior wings

unicolourous gray, their fringes with a faint purplish gloss.

Legs greenish-gray or subolivaceous, or sometimes testa-

ceous with blackish femora, with pale testaceous hair.

Abdomen greenish ; appendices superiores finger-like, the

tips slightly expanded, curved downwards; appendices

inferiores distant, curved upwards, also finger-like; penis

with the tip expanded; ventral process of the antepenul-

timate segment flattened, the apex truncate, slightly ex-

panded and just turned down, the base with a small, pro-

jecting, triangular tooth.

Long. ¢ 2 4—5 mm.

Hab.—England, in lakes and slow rivers; common at

Ringwood. June, July, August. Sweden (M‘Lachlan’s

collection). Kolenati’s A. argyricola is possibly a distinct

species. I haye never seen A. multipunctata with a pale

band before the tip of the antennz, nor with whitish hair

upon the head and prothorax. ‘Tourists im southern

Sweden (Stockholm, Dalecarlia) should look out for this

form, to determine whether it is a variety only of A. mul-

Is this the sex of the preceding species ?” [ After Hagen. |

[The “preceding species” is Phrizocoma albicornis,

Hag., and therefore the question may be answered in the

negative, the difference in the spurring of the legs pre-

cluding their identity. When Dr. Hagen wrote, it was

not known that both sexes throughout a genus of the

Hydroptilide have the spurs alike in number, specimens

with 0, 2, 4 spurs being hitherto considered to be the

males of specimens with 0, 3, 4 spurs if both were caught

in the same locality. |

[ Dr. Hagen, in his “ Phryganidarum Synopsis Synony-

mica,” refers this species to the genus Agraylea. I am

inclined, however, to suspect it may be related to Phrixo-

coma. ‘The small size of the insect, and the remarked

shortness of the apical forks, seem to exclude it from the

first mentioned genus, though the number of forks stated

by Zetterstedt prevents its beimg classed with Phrizo-

coma. |

new species, &c. By A. G. Buruer, F.L.S.,

F.Z.8., &e.

[Read 3rd February, 1873. ]

In the preparation of the present list, I have found M.

Simon’s recent subdivisions (Hist. Nat. des Araign.) of

great use; he has not, however, described all the varieties

of spining in this multiform genus, and therefore I have

added several, adopting his view of their sub-generic

value. i

In this paper I have described nineteen species which

appear to me to be quite new, some of them being

brilliantly coloured, and others very remarkable in form.

I am indebted to the Rev. O. P. Cambridge for calling

my attention to Koch’s great work on the Arachnida of

Australia, now being published at Nuremburg.

Female; length of abdomen 3+ lines; breadth at widest

part, excluding spines, 4 lines; entire length 5 lines;

posterior lateral spines 7 lines.

General form and appearance of cephalothorax and

abdomen that of G. arcuata, but the long divergent

lateral spines of the same character as those of G. clavatriz,

from which they differ chiefly in their much greater length

and less abruptly formed club.

Cephalothorax pitchy, with central area behind caput

testaceous; an orange spot on each side of central oculi-

ferous prominence; eyes golden yellow; falces black,

castaneous internally ; maxille and legs pilose, brownish-

testaceous with the joints blackish, but the three front pairs

with femora bright testaceous; abdomen above dirty ochra-

ceous, with sixteen impressed black spots round the margin,

and four, forming a trapezoid in the centre ; spines six in

number, blue-black, pilose, divergent, straight, otherwise

arranged as in G. curvicauda; ventral surface dirty

ochraceous, speckled with black, deeply wrinkled trans-

General form of the preceding species, but the long

divergent lateral spines more slender, with the club curved

and more suddenly formed.

Cephalothorax black; eyes pale crystalline yellow;

falces black; maxille pitchy, testaceous at base; legs

brown, pilose; femora of two front pairs testaceous;

abdomen above smoky ochraccous, irrorated, especially on

the front margin, with black; impressed spots as in pre-

ceding species; ventral surface dull ochraceous, irrorated

I feel great pleasure in naming this truly remarkable

species after my friend the Rev. O. P. Cambridge, to

whom I am much indebted for assistance received since I

took up the study of Apterous Insects ; it resembles very

remarkably'the crustacean genus Gvthra (near to Crypto-

podia). Mr. Pickard Cambridge tells me that he pos-

sesses two fine examples, and that there are several others

in the University Museum at Oxford, all from Africa; its

nearest ally, so far as I can judge from the figure, is the

Gasteracantha Gayi of Nicolet.

I had some thoughts of separating this as a genus from

Gasteracantha; it however differs little more than several

of M. Simon’s sub-genera; I have, therefore, retained it

in the genus, merely distinguishing it as M. Simon has

done with other forms by a sub-generic name.

The following species are unknown to me, and may,

perhaps, not belong to this genus :—

extremity, resembling a little column; Koch figures a

species of Tholia (T. turrigera) with this character.

VIII. Descriptions of Aculeate Hymenoptera of Japan,

collected by Mr. GrorcE LEwIs at Nagasaki

and Hiogo. By FREDERICK SMITH.

[Read 17th February, 1873.]

Tuts collection is specially interesting, not only on account

of its being the first, of any. extent, that has been investi-

gated and described, but also from the amount of interesting

addition which it makes to the knowledge of geographical

distribution of genera and species. The collection con-

tained several additional species of Andrenide, but as the

whole were sent in spirit, these pubescent insects were not

in a condition desirable for description, the hair being

matted together, and the original brightness of the colour

evidently destroyed.

I received eighty species of Aculeata; of these, fifty-

two I believe to be undescribed; the others, twenty-eight

in number, are well-known species, described from speci-

mens obtaimed from North China, India, Borneo, and

islands in the Indian and Australian regions of the Archi-

pelago. Only three insects are identical with species

found in Europe, and two with species of North America.

On a future occasion I hope to publish descriptions of

a number of Tenthredintde and Ichneumonide, and also

some very interesting species of Formicidae, received at

the same time as the Aculeata.

At the time that I described this species I was not

aware that the name had been used by another Entomo-

the name “‘ japonica” was given, proves to be my own IV.

mandarinia, described five years previously, it is not neces-

sary to alter the name. Since describing V. japonica ¢,

I have received numerous workers, which are coloured

similar to the male, but are rather smaller in size.

probably the males of each, if compared, would offer good

differential specific characters.

The queen of this species, which I have received from

Myx, Lewis, is smaller than that of A. medlifica, being about

two-thirds of its size; it is so like that species that a

comparison of the two is necessary in order to detect

any difference, but the posterior legs are proportionately

broader, and the tarsal joints also differ slightly in form.

It has none of the bright-red colouring of the worker.

Mr. Lewis found it dead near to a hive of “ nigro-cincta,”

und he informs me that he has not observed the Apis

mellifica in Japan.

period. The German ‘“ Berichte iiber die Entomologie,”

the * Zoological Record,” the “ Record of American

Entomology,” the “ Petites Nouvelles Entomologiques,”

and the numerous bibliographical reviews issued by learned

bodies and scientific journals at home and abroad, all com-

bine to provide inquirers with the necessary information.

The “ Catalogue of Scientific Papers,” published under

the auspices of the Royal Society, and the “ Bibliotheca

Entomologica” of Dr. Hermann August Hagen, are of

course quite indispensable to any one desirous of tracing’

either the work done by certain workers, or the history of

any special branch. As regards the last-named work,

every Entomologist ought to be truly grateful to its learned

and industrious author. For my own part, I confess that

it has become to me almost as indispensable as my daily

bread; and that it has not been very often the case, that,

in matters of scientific importance, its pages have been

referred to in vain. ‘The book is a safe guide on the

royal road to entomological knowledge, and this being the

case, it would seem to be the duty of those who have

profited by it to place on record such additions as they

may meet with in exploring the byways of literature.

Hoping that others will follow my example, I hereby beg

to offer a first instalment of such additions. With a

single exception, I have abstained from offering any com-

ments on the value of the works enumerated, as I hold with

Dr, Johnson, that “no book is so worthless as not to

contain something good.”

Following Dr. Hagen’s example, I have included works

written for incipients and children, as their enumeration

may be useful to those engaged in teaching popular

“ Be candid, kind reader — and judge as you please,’

“ But if you are morose — you will be stung by the bees !”

(Contains satirical remarks on court life and customs, but no

entomological matter. Is placed here merely on account of the

title and of the motto, to save Entomologists the trouble of

referring to it.)

X. On the Geodephagous Coleoptera of Japan.

By H. W. Barzs, F.L.S.

[Read 17th February, 1873.]

THE following enumeration and description of the Cicin-

delide and Carabide of Japan are founded chiefly on the

magnificent collection made by Mr. George Lewis during

a five years’ residence in that country, chiefly at Nagasaki,

in the island of Kushiu, and at Hiogo and Osaka in the

main island of Nipon. Although these two families had

already received much attention, chiefly from Russian

travellers and residents, and a large number had béen

described by Morawitz, Motschulsky, and others; Mr.

Lewis has more than trebled the number of known species

from this country, and added 120 new species to science.

The total number now known is 244 species, comprised

in 84 genera, a number that will no doubt be yet con-

siderably increased, as the British Islands, lying in a much

more northerly latitude, contain many more, viz., 311

species. It is not very probable, however, that future

discoveries will alter materially the general character of

the Fauna of Japan in this department ; for, although the

larger portion of the island of Nipon to the north and

east is as yet unworked; collections have been received

from many distant points on all the islands, and they show

a tolerable uniformity in their productions. We may con-

sider, therefore, that we have now material sufficient to

afford a fair idea of the relations of the Coleopterous

Fauna of Japan with that of other countries whose pro-

ductions are equally well known; and the Geodephaga

may be taken as very good representatives of all the

Coleoptera for this purpose.

The first stage in the inquiry is the most difficult, viz.,

how far is the Fauna of Japan endemic or peculiar? the

difficulty arising from our ignorance of the productions of

that part of the Asiatic continent which lies nearest to

the islands, viz., Korea. The straits between the larger

islands of Japan and Korea are partly bridged over by

smaller islands, so that the widest space of sea to be

TRANS. ENT. SOC. 1873.—PART Il. (MAY.)

220 Mr. H. W. Bates on the

traversed in passing from the one to the other does not

exceed thirty miles, or a little wider than the Straits of

Dover. Moreover, the sea is shallow, the maximum depth

being about 70 fathoms, so that an elevation of say 500

feet, ° which may well have taken place during the life-

time of existing species,—would convert the Archipelago

into a peninsula of Asia. ‘The islands, therefore, are not

geographically oceanic, and we can scarcely expect a great

degree of endemicity, such as is found in the Canaries,

Madagascar, and other oceanic or suboceanic islands whose

Fauna is not wholly modern and derivative. However, the

number of Geodephagous genera peculiar to Japan, in-

cluding that strangest of all, Damaster, is no less than

nine,—a large proportion out of eighty-four. I am in-

clined to think that this proportion will not be very much

reduced by future discoveries; although Korea is unknown,

we'are tolerably well acquainted with the Geodephagous

Fauna of the Amur a little farther north, and with that of

the coast region of the temperate zone ‘of China to the

east, where also Mr. Lewis made a most interesting collec-

tion; Carabide, moreover, have been collected to some

extent in the coast country of Manchuria, adjoining Korea,

and in the island of Saghalien, which almost connects the

north of Japan with the north-eastern mainland of Asia.

Next, as to the relations of the Japanese Fauna with

that of the great Northern or Palearctic Fauna of Europe

and Asia. Russian [ntomologists, who have worked

assiduously at the Coleopterous- Fauna of Siberia, have

repeatedly noticed its uniformity with that of EKurope,—

even Western Europe,—the similarity decreasing pretty

regularly, but, according to them, not very considerably in

proceeding from west to east. They have also remarked

on the essential identity of the Japanese with this great

Palearctic Fauna. Mr. Lewis himself, as he informs me,

was much struck with the similarity of Japanese Coleoptera

with those of Great Britain. Let us see how far these

views are confirmed by close examination of the distribu-

tion of the genera of Geodephaga. With regard to species,

the number common to J apan and Western Europe is

very limited.

A fair comparison between Japan and Western Europe

cannot well be made, for there is no tract of land in the

West analogous to Japan i in geographical position. Great

sritain is not at all a close analogy, as the whole of it lies

far to the north of the latitude of the Japanese Archipelago,

Geodephagous Coleoptera of Japan. 221

which is included between the parallels of 31° and 44°

north. A tract of land measured off in Western Europe

in the same latitudes would have its northern extremity at

Bordeaux and its southern at the Atlas Mountains. How-

ever, as the climate of the eastern side of northern con-

tinents is colder than than that of the western side, and

the Isotherm of 50° passing through the centre of Eng-

land and the north of Nipon, it would be fair to give the

European term of the comparison a more northerly ex-

tension, and compare Japan with a western area extend-

ing, say from the South of England to Tangier.

The number of genera of Geodephaga found in this

part of Western Europe is ninety-six; the number com-

mon to Western Europe and Japan only forty-four, nearly

all of which are universally distributed, or at least over

the temperate zones of the earth. There are no fewer

than fifty-two (or more than one half,) West European

genera of Carabide unknown to Japan, and vice versd,

thirty-eight Japanese genera are unknown to Western

Kurope. I think this is conclusive that there is no identity

between the two Faunas, and that their origin is, therefore,

not to be explained by the same set of causes.

There is a rather closer connection between the Japanese

Geodephagous Fauna and that of Eastern Siberia; but

there is an equally close, perhaps closer connection between

it and the Fauna of Kastern tropical Asia. Of the eighty-

four Japanese genera, twenty-one are elsewhere found only

between the tropics, chiefly in Asia. It is striking to find

in Japan some of the most curious Geodephagous genera of

Birmah and India, such as Kustra, Bothynoptera, Crosso-

glossa, Dicranoncus, and others, which have not yet been

found even in China. Other tropical genera also repre-

sented in Japan are Colpodes, Drimostoma, Trigonotoma,

Triplogenius, Calleida. On the other hand, the more

boreal of the European genera extending throughout

Siberia, and some of them through North America, are

absent from Japan, such as Notiophilus, Elaphrus, Ble-

thisa, Pelophila, Leistus, Loricera, Miscodera, Stomis,

and many others. The most characteristic genera inhabit-

ing Western Europe in similar latitudes to Japan are also

wholly absent, such as Stagona, Broscus, Licinus, Aristus,

Ditomus, Carterus, Acinopus, Ophonus, Olisthopus,

Molops, Pogonus, and others.

Professor Asa Gray, the eminent botanist, announced

many years ago in a treatise on the Japanese Flora, that

222 Mr. H. W. Bates on the

there was a distinct affinity between the Flora of Japan

and that of the Atlantic States of North America, i. e.,

genera are found in these two regions which do not exist

elsewhere. I have naturally been curious to ascertain

whether the Geodephagous Coleoptera showed any trace of

this curious connection, and am able to say that there is

an unmistakable trace. It is in the well-marked genus

Lachnocrepis, allied to Oddes, of which I here describe a

species, and which is at present known from no other part

of the world than the South-Eastern States of North

America and Japan. There is no similar connection

between Japan and the Western side of N. America, or

‘the Western side of Europe. There are traces of simi-

larity too in the genus Pristodactyla, allied species being

found in Japan and in Eastern North America. I am

inclined to attribute this singular relationship of Faunas by

the migration of Northern types from their Miocene homes

in the arctic circle on the advent of the glacial epoch.

The species would migrate along different meridians

towards the South, and such as were adapted to the ex-

treme climates of the Eastern sides of both the great con-

tinents would finally settle there, or at least that remnant

of them that escaped extinction.

This handsome and well-known Cicindela, according

to Mr. Lewis’s notes, is abundant everywhere in Japan;

frequenting the neighbourhood of water, especially run-

ning streams, March to November. It is common also in

China, from Hong Kong to the Yang-tsze. I have seen

it stated that the Japanese specimens form a variety, dis-

tinct from the Chinese; this may be true as regards those

found at Hong Kong, which are bluer in colour, and

have less of the coppery tinge on the thorax and the base

and apex of the elytra; but specimens from Ningpo do

not differ in these respects from those of Nagasaki.

Also a well-known species, somewhat resembling the

European C. sylvatica (which extends its range into

Eastern Siberia), but differmg greatly in the shape and

colour of the labrum, which is white, and scarcely pro-

duced in the middle.

Found in the dry season (February to June) abundantly

on hill sides and in woods, everywhere.

C. Japanensis, Chaudoir, Bulletin d. 1. Soc. Imp. des

Naturalistes de Moscou, 1863, p. 2.

Considered by Chaudoir to be a local variety of the

common European C. hybrida, and defined in these

terms :—

“Inter minores, colore cum typo convenit, supra

226 Mr. H. W. Bates on the

tamen paulo obscurior, lunulé humerali late interrupti,

fascié medié minime marginataé, longius descendente,

obliqué, medio attenuata, lunula apicali tenui.”

The reason which induces Baron Chaudoir to consider

the Japanese insect as a local form of the widely-spread

C. hybrida is apparently the existence of a numerous

series of connecting varieties, found throughout the

Northern Hemisphere of the old world along temperate

latitudes between Japan and Western Europe. Other-

wise, the well-marked and constant differences offered by

C. Japanensis would probably have led him to consider

it a distinct species, and as such I prefer to treat it. It is

always smaller than C. hybrida (5 to 54 lines), and of an

olive-green colour, with silky cupreous reflections, and

with the sides of the breast, and a broad ring round the

femora and tibix, brilliant coppery. The thorax has

similar straight sides, but it is more distinctly narrowed

behind. The elytra in the @ have each, near the suture,

and at a short distance from the base, a rounded dusky

depression, which I do not see in C. hybrida, or any of

its varieties that I have examined. The white belts and

spots of the elytra are, in all Mr. Lewis’s specimens, as

described by Baron Chandoir, viz., the humeral lunule

is separated into two distant spots, the submedian fascia is

oblique and rather narrow, without dentiform projections

or thickened portions, and the apical lunule is very slender

in the middle.

Very abundant in the sandy beds of rivers at Osaka

and Kobé.

Long. 7—73 ln. ¢ ¢.

The form of the white marks of the elytra in this species

is exactly as in the typical form of C. hybrida; the shape

of the head is also very similar, the eyes being only mode-

rately prominent and the forehead very little depressed.

But there the similarity ceases. The labrum in C. Lewisii

is, in both sexes, remarkably short and broad, with nearly

straight anterior edge (subdenticulate in ¢), and much

rounded angles. The clytra are greatly elongated, with

Geodephagous Coleoptera of Japan. 227

nearly parallel sides; the sutural apex spinose in both

sexes ; they are opake, but rather closely studded with

glossy elevated granules, much more minute than those of

C. hybrida and allied species. The great length of the

elytra makes the head and thorax appear relatively short.

The maxillary palpi are reddish, with the second joint

partly, and the third and fourth wholly, brassy green.

The labial palpi are pale testaceous, with the terminal

joint only brassy green.

Long. 7—8 lin. $ ¢.

Motschulsky gives five lines only as the length of

this species, but as his measurements are very frequently

erroneous, and his figure accurately represents the present

insect in size and markings, I feel no doubt that the deter-

mination is correct, especially if we may assume a little

inaccuracy in the figure as to the rounding of the shoulders

of the elytra, which in our insect are very distinct, and

even produced a little forward. The tibiz, and even the

tarsl In some specimens, are more or less rufous. The

white hairs of the flanks of the body beneath are adpressed

or subtomentose, as in C. stgnata and other long-legged

species, between which and the cancellata group this

remarkable and elegant species must be placed.

Mr. Lewis found it in the sandy beds of rivers near _

Kawachi. Motschulsky records it as having been taken

at various places along the banks of the Amur and Usuri

by MM. Schrenk and Ditmar, and Madame Gachkevich,

and also at Dolé and Kidsi. His correspondents, how-

ever, did not meet with it in Japan.

As Morawitz rightly observes, this species belongs to

the same group as C. trisignata of Europe. In fact, it

differs no more from C. trisignata than C. Japanensis

does from C. hybrida. It is a little smaller and less

coppery in colour, and the white markings of the elytra

are narrower, and more sharply limited.

Osaka; sandy places in August. Mr. Lewis also cap-

tured the species abundantly on the shores of lakes at

Kuu-Kiang, on the Yang-tsze,in China; and I have a

specimen taken by Mr. Arthur Adams, on the coast of

Manchuria. According to Morawitz, it was met with by

Maack and Radde on the Amur and Usuri rivers.

C. Elise of Motschulsky may, perhaps, belong to the

same species; but if so, he has given not merely an in-

sufficient but a false description, so that his name cannot

be adopted.

C. speculifera, Chevrolat, Revue Zool., 1845, p. 97.

Named from the small, mirror-like spot on the anterior

part of the disk of each elytron in the 2; a character in

which it agrees with numerous other species more or less

closely allied to it. Japanese specimens do not difter

in the slightest from those of Hong Kong. In size

they vary from six to seven lines in length, which is

much larger than the Indian species C. undulata, De).

(43 lines), with which it is united in Gemminger and

Harold’s Catalogue.

It is found in Japan only during the summer rains in

August, in moist paddy-fields and on roads. Hiogo,

specimens taken by Mr. Lewis shows that the characters

relied on by Morawitz to distinguish this species from the

European O. limbatus are not constant. Thus the four-

teenth and fifteenth elytral striae are sometimes confluent

long before the apex, as is generally seen in O. limbatus,

and the twelfth stria is abbreviated only in one example.

I find, however, O. limbatus varies in these points. The

only differences between the two forms that I observe

are size (O. equalis being 3} lines long) and the dis-

tinctly straighter lateral margins of the thorax in O.

equalis, with much more produced and less deflexed

anterior angles.

The famous Damaster blaptoides was met with by Mr.

Lewis only in “deep peaty woods, in the granitic district,”

near Nagasaki. All specimens of Damaster found elsc-

where in Japan differ more or less from this, which is the

largest form. ‘The size of the specimens brought home

varies from 1 in. 8 lines to 2 in. 5 lines (including the

elytral mucro). Besides the larger average size, this

species is distinguished from the allied forms by the much

longer elytral mucro, which in some males measures a

quarter of an inch in length.

the longitudinal line of the thorax and the legs. The

Japanese themselves, however, distinguish the two forms,

and when a long series of specimens of each are compared,

the smaller size, more slender figure and shorter mucro of

D. Lewisti are sufficiently conspicuous. In size it varies

Mr. Adams has recently informed Mr. Lewis that it

the two islands are on the same coast, not many miles

Carabus DeHaaniti, Chaudoir, Bull. Mosc. 1848, iv.

Among the numerous described species from Japan and

North China belonging to the C. prodigus group, the

present is distinguished by its large size (15 to 18 lines),

blueish-black colour, impunctate striz of the elytra, and

the presence of a fourth distinct “chain stria” towards the

lateral margin of each elytron, beyond which there is a

broad rugose space and indications of other striz. All

the numerous examples I have seen of the two sexes agree

in these features. ‘The general form of the insect is broad,

and only moderately convex; the thorax approaches the

cordate shape, that is, its widest part is before the middle,

whence it narrows moderately, in a slightly incurved line

to the hind angles. All the specimens agree in colour;

deep black, with a blueish tinge most perceptible on the

sides of the thorax and the elytra.

Very closely allied to C, Yaconinus, but undoubtedly

distinct as a species. It has relatively much longer and

less oval elytra, with the striz and interstices much less

sharply cut, thus receding from the well-marked type of

sculpture offered by C. prodigus. The striz are regularly

and rather coarsely-punctured, but the interstices are not

so crenated towards the margins and apex as in C. Vaco-

ninus, consequently the 3 cost exterior to the 3rd chain-

stria are much more distinct, and the central interstices

extend to the apex. The 4th chain-stria is reduced to a

row of granules. The colour of some dozens of examples

that I have seen is light brassy-green, chiefly on the inter-

stices and margin; very rarely it is violet-black with green

margins.

finding much variation.

224 millim.” Moraw, |. ¢.

In most of the examples of this species, two characters

are observable which distinguish it from its allies; 1, the

thorax broadest in the middle; and 2, the impunctate striw

of the elytra. Examples however occur in which the

thorax is broadest before the middle, and the striz distinctly

crenated ; thus a satisfactory diagnosis is not possible. It

varies also in colour, sometimes being “ subcupreus,” but

generally blueish-black, like C. DeHaanii, some examples

being brassy-cupreous, as bright as C. Matyasanus ; but

I have seen no specimen coloured like C. znsulicola. The

sculpture of the elytra in the punctured examples differs

from that of C. Maiyasanus only in the punctures not

being visible in the bottom of the striz, but only as crenu-

lations on the sides of the interstices.

Morawitz’s three specimens came from Hakodadi. I

have a specimen taken also at Hakodadi, agreeing exactly

as to form and sculpture with his description, but of a

blucish-black colour, and agreeing still closer with Chau-

doir’s description of his C. striatus from the north of

China. Mr. Lewis found cupreous and blue-black examples

with simple and crenated striz at Nagasaki. The Japo-

nicus of Motschulsky, of which two different and equally

insufficient diagnoses were published, seems to agree best

with the typical form of Albrechti, although his figure

represents the thorax as broadest in front; his corvinus is

undoubtedly a blue-black variety of the same with crenated

strie, and his multistriatus a more strongly punctured

variety.

234 <M, H. Wet Batesonthe

The only species here described with which C. Albrechti

may be confounded is C. Yaconinus, which is, however,

always larger, with thorax much more narrowed behind

than before, and striz much more conspicuously punctured.

C. Maiyasanus is sometimes precisely similar to Albrechti

in form (even of the thorax) and in colour, but the red

tibiz and tarsi amply distinguish it.

The synonymy of the species is as follows :—

from the angle is not rounded, but straight or even in-

curved, and the posterior narrowing is much more gradual.

conspicuous patch on each side at the apex, which con-

tinues for some distance along the extreme lateral edge.

But in a series of specimens taken by Mr. Lewis at Kiu-

none in which the punctuation entirely fails. ‘The peculiar

form of the thorax at once distinguishes the species, in all

its varieties ; it is much more neatly square than in any

of its near congeners, dilated very slightly at one-third the

length, and thence very gradually, straightly and mode-

rately narrowed to the base; the hind angles are rectangular

apex. Hustra is distinguished as a genus by its acumi-

occipital groove runs across from the back of the eyes,

Closely allied to the common European D. globosus,

differs in the elytral strize being distinct nearly to the apex.

It is the punctures of the striw, however, that are the most

distinctly visible, and in this the species differs from most

of its congeners; the punctures are large, and situated in

impressed strive on the disk, but on the sides and towards

the tip are simply arranged in rows. The circular foveole

near the scutellum is isolated from the sutural and second

This new genus is formed for the reception of species of

Eudema which present the striking peculiarity of a bilobed

fourth joint to all the tarsi in both sexes. In this character

it agrees with Kuschizomerus, but in that genus the lobes

are long and rounded to all the feet, whilst in Dischissus

the lobes on the hind feet are not so fully developed, being

acute, and therefore only to be considered as prolongations

of the angles of the fourth joint; in the anterior and

244 Mr. H. W. Bates on the

middle feet they form true lobes. The genus differs from

Euschizomerus also in the broadly-toothed mentum (like

Eudema), this organ in Luschizomerus being without

tooth; a suture separates the tooth from the body of the

mentum.

In facies the species offer no peculiarity. They are

doubt that the species is the same as the Japanese one, his

description being (unusually for him) exact and full. But he

had no reason whatever for referring it to the genus Pero-

nomerus, the essential character of which is the large size

and unilobular form of the first tarsal joint of the anterior

feet in the 6. The thorax in D. quadrinotatus is suboval,

much more narrowed anteriorly than behind, with rather

produced hind angles, and yellow lateral border, which is

broadish near the base, and narrows to a point before

tinctive characters very clearly. P. eratus of Dacca, in

This species is interesting as belonging to a genus

hitherto known only as inhabiting the Atlantic States of

North America. It is distinguished from Oddes by the

four basal tarsal jomts in both sexes having their soles

clothed with a dense brush of soft hairs, and by the 4th

joint of the anterior tarsi in the ¢ being dilated. In the

Japanese species the three basal joints of the ¢ anterior

tarsi are clothed in the middle with erect hair-scales (the

so-called papille of some authors), which I do not detect

in the 4th joint, in which soft hairs clothe the sole. I

believe this is the case also with the North American

species (L. parallelus, Say).

LI. Japonicus is rather smaller and much narrower than

LL. parallelus, with finer elytral striz, and more rufous

antenne and legs. The sides of the thorax, especially

towards the hind angles, are rufescent-pitchy, as in that

species.

I have little doubt this not uncommon Chinese insect is

the one described and figured by Redtenbacher, with the

erroneous locality, Auckland, New Zealand, appended to

it. The beautiful figure agrees in every respect, except

the prominent hind ‘angles, “which character is, however,

contradicted by the description “die winkel stumpf.”_ The

only discrepancy in the description is the heart-shaped

labrum, this organ being deeply sinuated, although much

less bilobed than in the other species. ‘The species differs

from its allies in its longer thorax, widest near the middle,

and narrowed quite as much in frontas behind. ‘The eyes

are not so prominent as in other species, and the edge of

the epistome is deeply sinuated. The legs and underside

of the body are glossy black, while the. upper surface is

rendered sericeous-opake by the minute rugosity of the

integument. In rare cases the elytral strix are finely

punctulate.

If the species be really found in New Zealand, Redten-

bacher’s name will stand; but, if not, I presume it will be

inadmissible.

The labrum is short and deeply notched. The thorax is

I agree with Morawitz in thinking it inadvisable to dis-

A curious species, distinguished by its rufous colour

(rusty testaceous above, pallid beneath), and by the elytra

narrowing from after the middle to the apex. The thorax

is short and broad, but not so wide as the elytra; it

broadens very slightly for a short distance from the ante-

rior angles, and narrows again from the middle, almost

imperceptibly to the base; the posterior angles are quite

rectangular, and the whole base is covered with punctures.

The elytra have a shallow sinuation near the apex; the

strize are simple and deep, and the setiferous puncture on

the 3rd interstice is large and conspicuous. ‘The anterior

tibie have their anterior outer angles produced and

oblique.

narrowed behind than before, and with rounded hind

angles; the basal fovez are large and rather deep, coarsely

but sparsely punctured; the reflexed lateral margins are

translucent pitchy-red. The elytra are oblong-ovate,

widened behind, obliquely sinuate near the apex ; the sur-

face is shining pitchy-black, with a slight bronzy tint,

becoming rufous-pitchy only on the extreme margins ; the

striz are : impunctate, the scutellar striole well developed ;

the interstices nearly plane, smooth, the 3rd with a punc-

ture behind the middle. The antennz are pitchy-black,

with the base and apex rufous; the legs pitchy-red. The

base of the abdomen in the ¢ has an oblong pubescent

fovea. The anterior tarsi in the same sex have widely

dilated triangular joints, the lateral angles in 2—4 being

acute, and the 4th angularly emarginate. The middle

tarsi are similar in form but much narrower.

General form short, oblong-ovate, with the thorax not

at all cordate, but narrowed in front and with nearly

straight sides behind ; hind angles rectangular, basal fovez

long and narrow, and the whole base sparingly but rather

coarsely punctured. The colour is variable; but the disk

of each elytron is always pitchy-black, leaving rufous

margins which occupy one interstice at the suture and

four at the sides and apex; the head and thorax are gene-

rally rusty-testaceous, with the disks piceous. The antennz

are short and thick for this genus, with joints 2—10 almost

268 Mr. H. W. Bates on the

moniliform, and the 11th oblong and stout; they are

rufous in colour, darker than the palpi and legs, which are

yellowish-testaceous. The head is similar in form to that

of B. harpalinus. The elytra are punctulate-striate, the

5th—7th strie very faintly impressed and the scutellar

striole wanting. Beneath, thé gula is remarkably large

and convex, and the thorax and abdomen punctulate.

The anterior edge of the prosternum is not marginated ;

the middle of the basal segment of the abdomen has an

elongate pubescent fovea.

In some respects this species agrees with Tachycellus,

but the middle tarsi of the ¢ are decidedly simple and

without squamz on the soles. The terminal joint of the

palpi is much longer than the penultimate, and the mentum

has a distinct acute tooth.

This insect has the general figure of Bradycellus har-

palinus, but is of vastly greater size, being 43 to 5 lines in

length. The generic character resides chiefly in the

absence of scales and hairs from the middle of the soles of

the dilated tarsi of the ¢. Both anterior and middle tarsi

are moderately dilated; the margins of the soles frmged

with long hairs, the centres naked. The head and thorax are

bright ferruginous-red, in the type, with the elytra pitchy-

black or brown; but Mr. Lewis took examples which have

the whole upper surface of the same piceous colour.

I do not know, and which has been variously recorded as

from India and the Cape of Good Hope. The general

colour is a dull coppery, and the whole upper surface very

densely clothed with short tawny hairs. The palpi are

brassy-black, except the extreme points, which are pallid.

The antennz are black or dark brown, with the Ist or the

Ist and 2nd joints reddish. ‘The thorax is transverse-

quadrate, moderately widened to one-third the length,

» then slightly narrowed posteriorly, forming obtuse hind

angles, the apices of which project a little; the surface is

as if corroded, impressed with large irregularly confluent

punctures, forming here and there coarse rugs, and all

the interstices covered with a fine punctuation. The elytra

are deeply sinuate at the tip; the striz are distinctly punc-

tured, and the 3rd, 5th and 7th interstices raised.

‘The paraglosse are large and connate with the lgula,

surrounding the apex and meeting above, as in the Le-

biade. The anterior and middle tarsi of the ¢ have four

joints moderately dilated, the soles clothed. with small

scales arranged in two rows.

It is not stated in Gemminger and Harold’s Catalogue

on what authority Platymetopus Thunbergi of Dejean

is placed as a synonym of Dioryche torta of Macleay’s

Annulosa Javanica and the universally-used generic name

of Dejean’s changed, in consequence, for the prior name of

Macleay. This very unwise change and confusion of

nomenclature are founded on a complication of mistakes

which could not possibly have been committed if the

original descriptions had been consulted. There is not

one point of agreement between the descriptions of Dio-

ryche torta and Platymetopus Thunbergi. The generic

characters given with Dioryche are vague in the extreme

and teach nothing, so that the name would have no right

to supplant another well-defined one in general use, even

if it were synonymous, which is not clear in the present

case, as D. torta probably does not belong to Dejean’s

genus. Dr. Gemminger (to whose superior eagerness to

change established names on any sort of excuse we owe the

* Catalogue” of Carabide) also separates the P. Thun-

bergi of Dejean from that of Quensel (in Schénh. Syn.).

This appears another unwarrantable change. Dejean

received his specimen from Schénherr himself, and his

description agrees exceedingly well with that of Quensel.

There appears simply to have been some error as to

272 Mr. H. W. Bates on the

locality. Quensel gives Cape of Good Hope and Dejean

(on the authority of Schonherr) “ Indes Orientales.”

The labial palpi are very slightly dilated from base to

apex and truncated, not much more so than in Dolichus ;

the species would therefore fit very well in the genus

Dolichus ; but this would entail the incorporation m the

same genus of all the North American species known to

me (P. impunctata, dubia, advena and Mexicana). The

present species has shining and not opake elytra, and the

thorax is about as long as broad, with very slightly arcuated

rately (with sinuation) to the rectangular hind angles ; the

whole surface, except the rufous explanated margins, is

glossy dark castaneous. ‘The shoulders of the elytra are

distinct, though rounded ; the strize are strongly impressed

and distinctly punctulated. The sulci of the tarsi are

lateral and distinctly marked only on the posterior pair.

narrow explanate margins. ‘The anterior tarsi alone have

the 4th joint bilobed and but briefly; in the termediate

it is deeply emarginated, with the exterior angle a little

more produced than the inner one ; in the hind tarsi it is

simply emarginated, without perceptible difference in

length of the two sides. The species therefore approaches

Anchomenus. ‘The hind tarsi are grooved on the sides

and not on the upper surface.

Distinguished from Colpodes by the tarsal claws having

a long tooth or spine at their base. I can find no differ-

ence between Japanese specimens and others from Northern

India (from the late Judge Benson’s collection) with which

I have compared them. Motschulsky’s description suits

as far as it goes, but he overlooked the structure of the

claws and placed it in the wrong genus.

Hiogo ; Nagasaki ; Yesso (Moraw.) Also China.

Very much resembles Colpodes atricomes, but the 4th

tarsal joint is triangular and barely emarginated even in the

anterior feet, showing that it does not belong to the same

genus. The form of the head and thorax is very different

and approximates that of A. (Limodromus) angusticollis,

from which it is distinguished by its much broader and

shorter thorax, with obtuse and strongly reflexed hind

angles, and by the much greater width and relative size of

the elytra.

The species belonging to Eschscholtz’s and Motschulsky’s

genus Limodromus ditter from the Anchomeni not only in

facies, but in the short and broad ligula scarcely visible

above the root of the labial palpi; the same organ being

narrow and porrect in Anchomenus. Platynus seems to

me also a very good group, and I cannot but think it was

a retrograde step in the science, to fuse these all into one

genus with the name first of Anchomenus (held for some

years) and then of Platynus.

Distinguished from A. protensus by the more elongate

thorax, more gradually narrowed behind and with pitchy-

rufous ‘explanated margins. The elytra too are very much

longer. The thorax is s Jess than one half the width of the

elytra, a little broader than long, with rather wide ex-

planated margins, which are turned up, especially at the

obtuse hind angles, and are more or less rufous-pitchy in

colour. The elytra are of great relative dimensions, more

than three times the length of the thorax. The legs and

tarsi are as In protensus and angusticollis.

and with almost acute hind angles; the surface is strongly

wrinkled transversely, the wrinkles mingled with punctures

which are much denser on each side of the base. The

elytra are less ovate than in A. prasinus, the strie very

deep and sharp, with a very regular punctuation; the third

interstice has in its middlé three punctures.

Very closely allied to the common Chinese A. scintillans

the abdomen being pitchy-black (like the rest of the under-

darker pitchy-red, and the surface of the thorax smoother,

with narrower and much less pallid explanated. lateral

margins. Both species are also very closely allied to the

Siberian A. bicolor (Dej.) which has paler, livid-brown

and only slightly seneous elytra, and rather longer thorax.

The colour of the elytra in A. chalcomus is always mode-

rately bright cupreous, similar to 4. parumpunctatus. A.

fallax (Moraw.) is another allied species, differing in the

broader thorax, not much narrower at the base than the

elytra,

Long. 14—14 lin. 8.

Closely allied to 7. Jimicola (Wollast.) from the Cape

Verde Islands. It isa little larger, less glossy, sides of

thorax distinctly less rounded, and apex of the elytra less

distinctly black. As in other species of Trechichus, and

to a less degree Mizotrechus, the 8th stria is more sharply

impressed than the rest, flexuous in the middle and led

round the apex, at some distance from the margin, to the

end of the suture, causing the discal surface of the elytra

to form a slight fold over the impressed line.

This species has a tooth in the emargination of the

mentum, and therefore differs from the definition of T're-

chichus given by Leconte after Zimmerman. I can confirm

the statement of these authors that the mentum is tooth-

less, in so far as I failed to distinguish a tooth in a specimen

of T. umbripennis showed me by Dr. Leconte. It is so

difficult, however, to be sure, without dissecting a specimen,

that I think it unadvisable to form a new genus on this

point of difference, until the North American species have

been thoroughly re-examined,

The present species, on dissection, proves to have a narrow

horny ligula surmounted by two sete, with paraglossx

adherent to the upper angles, and there obliquely truncated

upwards and outwards, without being longer than the

ligula; a very similar formation exists in the genus

282 Mr. H. W. Bates on the

Felis, subfam. Coptoderine. The anterior tarsi of the ¢

have four very slightly dilated ovate joints; and as far as

I can observe, under the compound miscroscope, all four

joints are furnished with membranous scales underneath.

As, however, the closely allied genus Mizotrechus offers

only three dilated joints, with scaly palms, in the ¢ (more

triangular than in T’rechichus), I am inclined to doubt the

accuracy of the observation with regard to Trechichus,

the minute size and hairiness of the tarsi rendering it

extremely difficult.

With regard to its other characters, the lobes of the

mentum are prolonged at the apex into fine points; the

labrum is quadrate and entire at the apex; the mandibles

and maxillz are long and slender, the last joint of the palpi

tapering to a point, as in Trechus. ‘The affinities of the

genus, together with Mizotrechus, lean certainly towards

Diploharpus, a genus of Anchomenine, but the adherent

paraglosse remove it from the Anchomenine; and as the

elytra are not truncated, but broadly rounded, it cannot be

placed in the Coptoderine subfamily of Truncatipennes,

to which it is allied in many respects. Baron Chaudoir

pointed out, long ago, the relationship between Diplo-

harpus and Stenognathus. There remains no alternative,

therefore, but to place the two genera in a separate sub-

family, which I think forms an additional link, to others

already known, between the Anchomenine and the Trun-

catipennes.

The genus T'rechichus is widely distributed. I have

seen specimens from North America, the Cape Verde

Islands, Penang and Australia, besides Japan, belonging

to very closely-allied species.

A curious little insect (3} millim.), resembling, accord-

ing to Morawitz, Trechichus (Lec.). The elytra are not

truncated, but rounded; therefore it cannot belong to the

Lebiine, where the author places it. The terminal joint

of the palpi is conical, as in Trechichus ; but the bilobed

labrum effectively distinguishes the genus. I have not

seen anything from Japan agreeing with this description,

but have no doubt that it belongs to the subfam. Tre-

chichine. It may be remarked that a species of the allied

genus Mizotrechus, viz., M. levigatus, has the labrum

somewhat deeply notched at its apex.

and before the middle begins gradually to narrow in an

incurved line to the basal angles, which are rectangular ;

the disk is very smooth; the basal fovez form long strie,

and their vicinity near the base is faintly punctured. The

Shape similar to Pt. (Platysma) oblongo-punctatus,

The head and antenne are very similar to those of Pla-

tysma, but the palpi are sharply truncated, and the meta-

thoracic episterna are much shorter. The thorax is rather

convex, and very smooth and glossy; the anterior angles

not produced, the sides gently rounded to beyond “the

middle, then sinuate-angustate to where the rectangular

hind angles slightly project; the base is coarsely but

faintly punctured ; the larger fovea is long and linear,

and there is an exterior much shorter one bounded on the

outside by a fold which extends to the hind margin. The

elytra are deeply striated, the strie very faintly punctu-

late, the interstices convex ; the posterior sinuation is dis-

tinct. Underneath the sides of the thoracic and of basal

abdominal segments are very strongly punctured.

it is more rapidly narrowed towards the base; the hind

angles are moderately produced and acute, the whole base

The whole insect is glossy black, except the palpi, which

are tawny-red; but the antennz are sometimes rufescent.

Although Motschulsky gives 74 lines only as the size of

his species, and says s the thorax is only a little narrowed

behind, I think it is the same as the Japanese one, espe-

cially as I have found specimens in a collection made in

In the form of the thorax and elytra similar to A. Quen-

little narrower than the middle of the elytra, owing chiefly

to the latter being gradually dilated to the middle, whence

they are narrowed again to the apex. The base of the

thorax is coarsely and thickly punctured, and somewhat

distinct and rounded; the exterior one is bounded by a

raised wheal. The elytra (and under-surface) vary in

colour and amount of metallic lustre ; their ground colour

is, however, always more or less rufo-piceous, which colour

appears in the margins of the darkest specimens. The

anterior tibize are not especially dilated, and their external

edge has a few longish bristles.

The species would be almost as well-placed in § Letoc-

gives it an appearance different from that of the species

placed in Letocnemis. The head is very short, and the

eyes prominent. The thorax is twice as broad as long;

more narrowed in front than behind, with anterior angles

standing far away from the sides of the head, and the hind

angles obtuse, except a small triangular projection; the

base is smooth in one specimen, and has a few punctures

in the foveze and near the hind angle in the other; there is

scarcely any trace of fold or wheal on the outerside of the

exterior fovea. The anterior tibiz are rather suddenly

dilated near the tip, the dilation much rounded, and its

outer edge furnished with a row of 5 short and stout spines.

chiefly on the emargination of the joint in question, it

margin is not visible in this species; but the large punc-

ture which marks its termination is plainly visible. ‘This

is nearly the same in ZT’ livida, but a shallow striole is

perceptible behind the puncture. There are in both

brassy-black, except in immature specimens, where they

are of a uniform brown. ‘The palpi and antenne are

It is closely allied to B. Gebleri (Esch.) (= celestinum,

Motsch. ?), which has a shorter and broader thorax and is

a considerably smaller insect.

of the elytra generally covers the apical third, but deeply

emarginated in front on the suture; but sometimes the

sutural emargination continues to the apex, and in rare

cases the ground colour also indents the spot deeply on

each side; the apex itself, however, is never of the ground

colour, as in C. latifascia. In most examples one or two

narrow fulvous streaks extend along the lateral margin

nearly to the base. ‘The apical ventral segment is more

thorax is as long as broad, not cordate, but narrowing

slightly from its broadest part (before the middle) to the

obtuse anterior angles; behind it is narrowed a little more,

with slightly sinuated sides, which fall rectangularly on the

hind angles, although these are blunt at their apices ; the

black margins of the thorax are more or less broad.

I have compared specimens with Macleay’s type (from

than the slight prominence of the posterior angles of the

thorax, which seems also to be a little more rounded on

the sides in front.

The genus has been erroneously placed in the Helluo-

nine subfamily, from which it differs in the short truncated

labrum and the ligula furnished with very long, narrow

paraglosse, which are nearly three times the length of the

ligula, and are strongly curved. The ligula itself is short,

very convex, rounded at the apex, and furnished with

many long stiff bristles. The tooth of the mentum is fur-

rowed in the middle and notched at the tip. The sculp-

ture of the elytra (ill-described by Macleay) is like that of

the typical Galerite ; sharp ridges or raised lines, with

two smaller raised lines in each interval between them.

The underside of the body is coloured as in B. fumans,

except that the dusky border is more distinctly defined.

The general shape is also similar to that of &. fumans,

but the thorax is very different and peculiar in outline,

being very little rounded on the sides anteriorly, and not

narrowed to the anterior angles, which are distinct and

not deflexed. The elytra are oblong-ovate, with squared

shoulders; the cost, including the sutural, are seven in

number ; narrow, sharp and shining, of a darker hue than

the blueish-green of the interstices; an eighth costa appears

towards the tip in large individuals; the deflexed epi-

pleurz are blue. The legs aud antenne are rather more

elongated than usual.

If the species be the B. longicornis of Motschulsky, his

306 My. HW. W. Bates en the

name cannot stand, as the prior longicornis of Fairmaire

(1858) is a true Brachinus.

The species varies much in certain points. In form:

the degree of convexity of the elytra is very variable, and

so is the amount of abbreviation of the cost before the

apex. In colour: the antenns are sometimes concolorous

tawny-red, but most frequently more or less dusky-red, the

duskiness commencing at the third jomt in some examples

and not before the fifth in others; beneath the episterna are

sometimes red, and the sides of the abdomen dusky; more

frequently the metathoracic episterna are dusky, like the

sides of the abdomen; but in some examples the whole

abdomen is fuliginous, and in rare cases the mesothoracic

episterna are dusky and not the metathoracic. All grada-

tions are found, and the variations do not occur in con-

junction.

towards the apex. ‘The thorax is short and cordate, the

sides strongly rounded anteriorly, the anterior angles

deflexed and scarcely visible, strongly sinuated posteriorly,

with produced and acute hind angles; the surface is punc-

tate, faintly rugose, and pubescent, and there is a transverse

black vitta on the hind mar gin. ‘The elytra have distinct

but rather obtuse-angled shoulders, which arises from their

being dilated immediately from the shoulders towards the

becoming obsolete towards the base), the interstices are

minutely punctured and opake.

into the other. ‘The elytra are elongate, the striz broad

and shallow; the brown sutural vitta has a triangular

dilatation over the scutellum, and an oblong one at two-

thirds the length, after which it terminates; the lateral

vitta is of moderately equal width from the humeral to the

apical angle, leaving the lateral rim always fulvous; the

fascia is very variable in width and in intensity of colour,

but it always forms an angle, projecting forward almost as

pitchy-testaceous than the legs, which are yellowish-tawny.

The thorax is rounded, almost angulated on the sides

anteriorly, then yradually narrowed to the hind angle,

which projects as a small sharp tooth; the middle of the

base forms a short, broad, rounded lobe; the whole sur-

face is somewhat regularly and sharply transverse-striate ;

the lateral rims are extremely fine. The elytra are

very finely punctulate and alutaceous, deeply and simply

striated; the lateral margin, a short vitta within the

It agrees with the other characters of the genus, the

pluri-setose ligula, toothed mentum, sinuate and rounded

labrum, hairy surface of the. tarsi, and so forth; and as I

have another species from Bombay exactly intermediate be-

tween FH. Lewisti and Pradier?, there is reason for referring

them all to one genus, giving a little extension to the defini-

tion drawn up by Baron Chaudoir. The insect is much

312 Mr. H. W. Bates on the

broader than EF. Pradieri, and much darker in colour,

slightly shining. The antennz are very similar. The

head differs only in the greater convexity of the eyes ; it

is punctate on each side, and has some strige towards the

base of the antenne. ‘There i is a great similarity in the

outline of the thorax, but it is very much broader, and

the slight basal lobe is only a further development of the

arcuated base-line of Pradiert. The elytra are throughout

thickly punctulated, and have very distinct punctured

strie. The abdomen and metasternum are punctured and

pubescent.

Differs from the description and figure of B. dorsigera

of yellow patch from the middle of the elytra. The whole

upper surface is of a fine tawny-brown colour, highly

polished ; the margins and suture of the elytra are a little

lighter, or yellower, in colour; and so are the borders and

dorsal line of the thorax, and the sides and large frontal

spot of the head. ‘The antennz are pitchy-red, with the

scape yellowish; the palpi also, as well as the whole under

surface, are yellowish. The head has two broad and deep

frontal fover. The thorax does not differ in outline from

that of B. dorsigera, except in being conspicuously broader.

The elytra widen gradually and slightly from base to

Clayey-red, shining. The greenish-black vitta of the

elytra covers the 6th to the 8th interstices in the middle

of its course; but near the base it extends also over the

5th, and at the apex it curves a little, leaving the 8th, and

extending over the 5th to the 2nd; the surface of the

elytra 1s uneven, causing the striz to be more deeply sunk

in some parts than in others ; the striz are finely punctu-

late, and the interstices sprinkled with distinct punctures.

The head is punctulated, especially in the long frontal

furrows. The thorax is not quite so broad as the head,

with narrow explanated margins, angulated before the

middle, and slightly sinuated, but not narrowed, behind to

the obtuse hind angles, which are rendered more obtuse by

the obliquely truncated base immediately contiguous; the

surface has numerous scattered punctures, which are denser

on the anterior border.

Elytra spotted similarly to L. cyathigera, but the species

belongs to the same group as L. Japonica, having deeply

striated or sulcated elytra, and strongly bilobed 4th tarsal

joits. The head and thorax are somewhat redder than

the rest of the body and limbs, and are very finely aluta-

ceous and sub-opake. The thorax is rather short and

strongly transverse, with broad explanated margins,

broadly rounded from the anterior angles and scarcely

narrowed behind to the rather obtuse, but somewhat pro-

minent, hind angles. The dark markings of the elytra

consist properly of an elongate-ovate spot over the suture,

about the middle, which is connected anteriorly with an

ill-defined triangular one over the scutellum more piceous

or reddish in colour, and of a rounded discoidal spot on

each elytron behind the middle.

No difference is perceptible between Japanese examples

hind trochanters, the apex of all the femora, the tibiz and

the tarsi being black. It approaches nearest, therefore,

the S. European var. nigripes. I have specimens from

The head is subopake ; labrum and palpi piceous; antennze

pitchy-black, with the extreme bases of the joints pallid

testaceous. The thorax forms a broader or more truncated

peduncle at the base than in P. rujicollis. The elytra are

of a deep shining black, the deflexed margins (epipleura)

only tawny-brown, except in some examples this colour

extends to the upper edges; the striz are finely impressed,

much more deeply so towards the apex, and are strongly

punctured; the 3rd interstice does not show the two punc-

tures which are so conspicuous (especially the one near the

base) in P. ruficollis.

The thorax is less transverse, or narrower in proportion

to the length, than in other Asiatic species ; it is, however,

of the same pentagonal form, except that the base forms a

somewhat broader peduncle, obtusely truncated; its sur-

face 1s convex and very glossy, pitchy-black, a little clearer

on its margins. The head also is rather narrower and the

eyes less prominent ; and the antennz have conspicuously

thicker joints. The elytra have very strongly punctured

strize, but they become much fainter towards the apex.

To the four names (Rhombodera, Pentagonica, Didetus,

Elliotia) which this well-marked genus had received, Mr.

Wollaston has recently added a fifth, Xenothoraz, in his

“Coleoptera Hesperidum,” founded on a species, X. hera-

gonus, from the Cape Verde Islands. ‘This species is dis-

tinct from all others (9 in number) which I have been able

to examine, but it offers not the slightest ground for generic

separation. The basal peduncle of the thorax is much

broader and more truncated than in P. rujficollis, but every

species differs a little in the form of this part. The name

Rhombodera (Reiche, 1842), is prior to Pentagonica

(Schmidt-Goebel, 1846), but it was pre-occupied by Bur-

meister for a genus of Orthoptera in 1839,

other genera of Thyreopterine (Chaud. ), but the bisetose

ligula 1 removes it to the Coptoderine, according to Baron

Chaudoir’s definition ; ; and I cannot but think that it proves

the distinction drawn by this eminent Entomologist between

the two groups to be highly artificial. The eyes are not so

small and flat as in Miscelus, neither are they furnished

with a thick orbit behind, the head narrow ing very obliquely

from the eye to the neck.

the explanated margins of the thorax and the elytra, like

the antenne, legs and parts of the mouth, are pale tawny-

yellowish. The elytra differ somewhat in outline from

those of Stenognathus, Sinurus, &c. in being narrower,

especially at the base, where they are not much broader

than the widest part of the thorax; the shoulders are

obliquely rounded. The interstice between the 8th and

XI. Descriptions of new genera and species of Geode-

Bates, F.L.S.

[Read 17th March, 1873.]

‘THE following descriptions, founded in gr eat part on the

collections made by Mr. George Lewis in China, are

intended as a contribution to our ‘knowledge of the Geode-

phagous Fauna of that country, and as facilitating the

comparison between the faunas of China and Japan in

this department. It will have been observed that all

species common to the two countries have been indicated

in the foregoing memoir on the Geodephaga of Japan.

Cicindela Kaleea, Bates, Proc. Zool. Soc. 1866, p. 340.

This species, described originally from the Island of

Formosa, is found also in China. I have specimens from

Shanghai, and Mr. Lewis has found it at Foochow. It

varies considerably in size, in the relative length of the

elytra, in colour and markings. Sometimes it is tinged

above with a silky, tender green colour. The central

oblique white band is dissolved in some examples into

two spots, one discal and the other marginal, but there is

almost always a trace of a slender line uniting the two.

The species by its cylindrieal thorax and slender figure

belongs to the same group as C. germanica, gracilis, &c.

The maxille are very remarkable; projecting as very

slender, straight shafts far beyond the tip of the long,

straight, acute mandibles, and having a slender short hook

at the end; the inner side towards the apex armed with

a few horny teeth, and the basal part setose as in other

Carabide. I am not sure that the palpiform exterior

lobes of the maxillz are jointed ; they appear simple as in

Callistus, and are a little longer than the blade of the

maxilla, the tip of which they cover as a hood.

Similar in form to Br. harpalinus (De}j.), except that

the head is much broader and more obtuse (like Tachy-

portion to the length, and more narrowed from the middle

to the base. The terminal joint of the palpi is thicker,

but the apex is attenuated to a point. The first ventral

Closely allied to LZ. Hopei (vide Trans. Ent. Soc. 3rd Ser.

vol. i. p. 9, pl. vi. fig. 2), but the following differences upon

comparison are found to be apparent. ‘The mandibles are

somewhat longer, less circumflex, and furnished with seven

teeth instead of five, these being less regularly distributed :

the basal teoth inclining internally, instead of externally as

in L. Hope; the posterior angles of the head are con-

siderably more rounded ; the suberect lobe, so conspicuous

in the centre of the anterior margin of the head in L.

Hopei, is also entirely wanting; moreover, the sides of

the thorax are much less sinuate, with the anterior angles

less produced. I have but little doubt that both these

species in a normal condition are strongly pubescent upon

the upper surface. I am indebted to Count Mniszech for

the opportunity of notifying this interesting species. It

has been named after a young and zealous Polish entomo-

logist by whom it was captured, with other interesting

novelties, in the district of the Amur River, Dauria, and

transmitted to the Museum of Natural History in Warsaw.

A remarkable similarity exists between O. Lowet and

O. Brookeanus ; upon closer examination, however, the

two species are ‘found to be abundantly distinct. Unfor-

tunately, but one specimen of O. Lowei exhibiting a

minor development of the mandibles has at present fallen

under my notice, and having compared it with numerous

specimens of O. Brookeanus exhibiting various degrees of

development, the following differences are found apparent :

The entire length of Lowet, 24 inches, exceeds consider-

ably any specimen of its allied species I have met with.

The differences in form and sculpture of the mandibles is

at once conspicuous ; instead of being semicircular, as they

are invariably in O. Brookeanus, they are porrect, slightly

curved from the base to the apex, much narrower, and

with the upper surface more convex and covered with a

dense granulation. The head is more elongate convex,

with the anteocular angles rounded, not acute, and the

entire surface thickly granulated. The prothorax is wider,

with a black plaga, covering nearly the entire upper surface,

leaving only a very narrow rufous line at the base, with a

somewhat broader one at the sides; the posterior angles

are less emarginate, and the granulations are much denser.

The elytra are more elongate and narrower posteriorly,

very glabrous, and of a deeper yellow colour; the under

of nondescript Lucanoid Coleoptera, &c. 337

sides present a remarkable difference in coloration, for in-

stead of being, as in O. Brookeanus, uniformly testaceous,

it is variegated. The whole of the reflexed margin, to-

gether with the epipleure, are black, as also the prothorax,

save two indistinct lateral rufous patches.

This interesting addition to the Lucanoid Coleoptera

was discovered by H. Lowe, Esq., a gentleman who has

contributed so much to our knowledge of Bornean ento-

mology.

M. Blanchardi is readily distinguished from its allied

by its very pale luteous coloration, the form and armature

of the mandibles, and especially by the narrow black

central line exhibited on the disk of the prothorax ; this

character occurs only, to my knowledge, in two other.

insects belonging to this group, viz., the very rare Proso-

pocotlus suturalis of Oliv., and in P. Mohniki, now

described for the first ttme. To P. occipitalis, M. Blan-

chardi also bears a general resemblance, but the binodose

front of the head necessitates its location in the genus

Metopodontus. I may remark that I have recently seen

This species is closely related to P. occipitalis, Westw.,

but may readily be distinguished from it by its larger size

and denser colour; its head is more deeply excavated in

front, the carinz are considerably longer, extending from

the centre to the anteocular angle, and the sides behind

the eyes being merely swollen instead of dentate; the pro-

thorax has a large central triangular black mark extend-

ing from the anterior to the posterior margin, and the

elytra are very finely chagreened, whereas in the allied

species they are distinctly punctate. We are indebted to

Dr. Mohnike, a zealous entomologist long resident in the

island of Java, for the discovery of the present species,

stated to be from that island, where it has only recently

been discovered, but in very great abundance. Unfortu-

nately all the specimens captured of various stages of

development were males. I possess from the island of

Formosa a single female individual, which, were it not for

the divergence of locality, I should feel disposed to refer

to the present species.

I avail myself of the opportunity to add a few remarks

upon the species composing the genus.

The genus Lissotes was proposed by Professor West-

wood (vide Trans. Ent. Soc. N. S. iii. p. 213), and con-

tains the numerous Australian species Tbelanaies to the

family of the Dorcide, which are represented in South

America by the Sclerostomi of Dr. Burmeister (vide Hand-

buch der Entomologie), and exhibit such diversity of form

that I am now disposed to modify the grouping in my Cata-

logue of the several species at present known.

“Professor Westwood (loc. cit., p. 214) distributes the

species into two sections, characterized by the form of the

mandibles; but subsequently, in describing some interest-

ing new species (Trans. Ent. Soc. 1871, p. 353), he pro-

posed other characters as distinguishing the Tasmanian

species. It is upon these last characters that I have based

the following tabular arrangement, embracing the whole of

the Australian species at present known. I admit it is

not quite satisfactory, since it involves the approximation

of somewhat incongruous forms, yet it is nevertheless the

best I can at present offer :—

A. Posterior angles of prothorax oblique, with a prominent angle opposite

the shoulders of elytra.

a. Fore margin of prothorax anteriorily produced in the middle.

Allied to WM. Delegorguei, Thomson, but at once dis-

tinguished by the wider and more deeply excavated head,

by the strongly emarginate anterior angles of the pro-

thorax, as well as by the more uniform character of its

sculpture; the punctuation being regular and extending

over the entire upper surface of the prothorax, a character

not exhibited in any other of the African species; it is,

moreover, not nearly so shining.

In the British Museum collection there exists a specimen

of this insect, labelled “‘ Nigidius cribricollis,” Reiche, a

manuscript name which I have much pleasure in adopting.

angles, the punctuation is also considerably stronger (with

the exception of NV. obesus) than in all the other Asiatic

species we are at present acquainted with ; the scrobiculate

character of the punctuation exhibited in the interior of

the fovea on the thorax in the African species appears to

be wanting. I am indebted to Count Mniszech for the

specimen I possess.

As no well authenticated specimen of this insect has

fallen under my notice, I am not in a position to decide as

to which of the West African species of Wigidius at present

known WN. Bubalus of Swederus is to be referred; it has

even been suggested to me that the insect in question -

might possibly not even belong to this genus; but I think

from the description, as well as from the figures (although

but indifferently executed), that there can be but little

doubt upon this point. The habitat given by the author,

of North America, is evidently erroneous; and seeing that

Drury’s collection was especially rich in West African

species, it is most probable that from thence the insect

originated. (Possibly the type specimen may still exist in

the late Mr. Macleay’s collection in Australia, who, if I am

correctly informed, purchased largely at the sale of Drury’s

collection.) Judging from the description and the figures

given, the following two species, viz. NV. auriculatus, Klug,

and WV. auriculatus, Guérin, both from West Africa, appear

to me to be the most nearly allied to Bubalus; but as

Swederus, neither in the description, nor the figures, alludes

to a very important character peculiar to WV. auriculatus

of Guérin, viz. the deeply emarginated anterior angles of

the prothorax, a character which does not exist in NV. auri-

culatus, Klug, I am very much disposed to believe that

the above synonymical arrangement will prove to be

correct, especially as, through the kindness of Professor

itn Sn

of nondescript Lucanoid Coleoptera, &c. 343

Westwood and Count Mniszech, considerable additional

material, enabling me to arrive at this conclusion, has been

available to me.

The species composing the genus Migidius may be sec-

tionized thus :—

A. Mandibles robust, with a recurved process at the base in both sexes,

less produced in the females.

a. Prothorax rugose, punctate with a central fovea, anterior angles

more or less emarginate. JV. grandis: N. Delegorguei: N.

auriculatus: N. cribricollis.

* Anterior angles of prothorax non-emarginate. IV. Bubalus:

NV. cornutus: NN. distinctus: NV. obesus,

6. Prothorax smooth, non-foveate; anterior angles of prothorax

produced, non-emarginate. JV. levicollis: NV. formosanus.

B. Mandibles ¢ slender, evidently recurved at the apex, with a nodose

tuberele at the base; @ mandibles less recurved and simple. Pro-

thorax smooth, non-foveate. JV. Madagascariensis.

C. Mandibles simple. Prothorax smooth, with acentralfovea. WV. Parryi:

LV. trilobatus.

Having recently had the opportunity of examining

numerous specimens of the several insects alluded to above,

I have arrived at the conclusion that Dr. Burmeister (loc.

cit.) is fully justified in uniting them as one species. With

reference to the character specifically assigned, to the

number of striz exhibited on the elytra, this character is

found, as already alluded to by Dr. Burmeister, to be most

capricious: the stria, or their rudiments, varying from

1 to 6.

In the var. F. nigrita, Westw., exhibiting a somewhat

small development of this species, the punctuation on the

sides of the prothorax is somewhat stronger, but in other

respects corresponds with a specimen in my collection of

F. anthracinus, Klug.

Figulus trilobus, Westw. Ent. Mag. v. 263.

Hab.—N. Hollandia.

Figulus trilobus may, I think, with great propriety be

removed to the genus Vigidius, to which it appears to me

344 Major F. J. Sidney Parry on the characters

to assimilate more closely in the following respects: the

short robust mandibles, which are slightly recurved at the

apex; the deeply excavate head, with the sides rounded

and strongly produced; the form of the thorax, with its

anterior trilobate process; and, finally, the elytra, on

which the costa are more prominently defined, the sculp-

ture of the interstices, as well as the punctuation, being

considerably stronger than in any species pertaining to the

genus Figulus. N. trilobus belongs to the third section

of the genus, characterized by the mandibles being simple,

or unarmed, on their upper surface.

FIGULUS.

Sectional arrangement.

The species belonging to the genus Figulus may be

thus seetionized :—

A. Elytra smooth, partially striate. 2. levipennis.

B. Elytra partially, but irregularly, punctate-striate. 7. sublevis.

C. Elytra regularly punctate-striate. 2 striatus, F. regularis,

Ff. foveicollis, Manillarum, Scaritiformis, and others.

XIII. Remarks on the affinities of the genus Micagus,

Leconte. By Mons. Henri Deyrolle. Communicated

in a letter to Major F. J. Sidney Parry, F.L.S.

“ T have availed myself during the past few days of

certain leisure time to examine your beetle attentively, and

regret that I am compelled to differ entirely from our

learned and esteemed friend Mr. Westwood,* and find that

it is impossible to separate Micagus from the Lucanide,

and that I cannot locate it satisfactorily among the Lamel-

licornia, in whatever group I attempt to place it.

“Tt presents one slight differential character, and one

alone, from the Lucanide, namely, the narrow mentum,

but in all other respects it coincides so entirely that I have

not the shadow of a doubt that the position of Nicagus is

in close proximity to Mitophyllus.

“Observe that all its organs correspond with those of

that group; take for instance for comparison a female

specimen of your M, zrroratus: the head I find is nearly

similar; the antenne likewise, with the lamelle a trifle

thicker; the prothoraz agrees in every respect with that

* Proc. Ent. Soc., 7 March, 1870.

of nondescript Lucanoid Coleoptera, &c. 345

of the species of the group, crenulated as in them, and

with nothing analogous amongst the Melolonthide; the

legs, it appears to me, settle the question beyond a doubt,

for in no group of Lamellicornia do we meet with this

characteristic form of the anterior tibie, so elongate, square

at the apex, dilated at the tip, dentate like a saw behind

the large teeth; the tarst with the claws very large are

identical with those of Mitophyllus ; the body has entirely

the form and characters of those of the Lucanide; the

margined abdomen fitting close to the reflexed margin of

the elytra is entirely that of a Lucanid, although this

character is found in many Lamellicornia; lastly, the

mandibles and palpi agree im every respect with those of

the family to which your insect should be referred ; and

I repeat that I entertain not the slightest doubt and do not

hesitate to consider it a Lucanid, and think that you will

participate in this opinion.”

Obs.—I should remark that Dr. Leconte has already

suggested the reference of this insect to the Lucanide.

NYCTOZOILIDES.

Nyctozoilus Deyrollei, n. sp.

This is the species I have alluded to (Trans. Ent. Soe.

1872, p. 271), in a comparison of its form with that of the

genus Saragodinus—as the N. obesus, Guérin. Having

since that time forwarded the specimen to M. E. Deyrolle,

he kindly compared it with the type of obesus, and, find-

ing it distinct, has furnished me with the following com-

parisons of the two species :—

JV. obesus, Guérin (type).

Head with a slight impression on

the vertex. ,

Prothorax narrower, the sides

regularly rounded and but little ex-

panded in the middle; front angles

slight, the apex with but a trace

of a thickened margin (“ bourrelet”’)

at each side; the lateral gutter conti-

nuous throughout its length.

Blytra with the shoulders

rounded, gradually widened at the

sides to two-thirds their length.

Flanks of prothoraz slightly in-

distinetly punctured in the middle.

Body (or form) narrower, more

oblong.

Long. 9 lin.; width of prothorax

across the middle 32 lin.

N. Deyrollei, n. sp.

Head coarsely, irregularly ru-

gose.

Prothorax broader, sides strongly

expanded in the middle, strongly

narrowed in front and behind; front

angles very prominent, the apex

thickly margined at each side nearly

to the middle; the lateral gutter in-

terrupted by a prominency in the

middle.

Elytra broader, more rounded at

the sides, shoulders very strongly

rounded, the greatest width towards

the middle.

Flanks of prothorax covered with

coarse, prominent wrinkles.

Body broader, more rounded.

Long. 93 fin.: width of prothorax

across the middle 4 lin.

Hab.—I1 cannot give any more definite locality than

** Australia.” A single example obtained from the col-

lection of Major Parry. Judging from the kind of ticket

attached to the specimen, I am strongly inclined to think

it came from Western Australia, as similar tickets were

attached to other insects that undoubtedly came from that

quarter.

STYRUS, n. g.

Near to Nyctozoilus. Head relatively narrower and

longer, front angles of epistoma less rounded, so that the

sides appear more parallel: eyes larger; antenne much

longer, subfiliform, moderately perfoliate, very slightly

depressed ; scape strongly obconic, joint 3 fully equalling

in length 4 and 5 together, subeylindric, 4—10 sub-

cylindric, or very slightly obconic, 4—8 subequal, 9—10

a little shorter, 11 longer than 10, rounded at apex, the

last 4 joints finely densely pubescent: prothorax nearly as

of new genera and species of Tenebrionide. 349

long as wide, a little narrower, and more thickly mar-

gined at apex than at base; apex strongly emarginate,

the angles prominent, acute, directed forwards; sides feebly

rounded; hind angles acute, directed behind, and reposing

on the shoulders of the elytra; base emarginate, slightly

sinuously sloping at each side from the middle of the

margin to the hind angles; lateral margins reflexed,

thickened, rather strongly crenate in the middle, broadly

channelled within; scutellum strongly transverse: elytra

obovate, middle of base emarginate, this—with the emar-

gination of the base of prothorax—leaves exposed the

scutum of the mesothorax; lateral margins very narrow,

slightly reflexed, a little sinuous behind the shoulders and

near the apex: epipleural fold narrower than in Nycto-

zoilus, entire: prosternum convex, longer than in Nycto-

zoilus ; its process robust, subhorizontal, broadly margined

at each side, prominent and narrowly rounded behind:

mesosternum subvertical, and deeply concave, in front, its

epimera posterior: metasternum—between the coxse—as

long as the 2nd ventral segment: intercoxal process wide,

broadly rounded in front: lst and 2nd ventral segments

slightly emarginate—and narrowly coriaceous —in the

middle behind, the 3rd and 4th sinuously emarginate, and

broadly coriaceous behind: J/egs rather long, slender;

femora feebly claviform ; tibie sublinear, feebly spurred,

the intermediate very: slightly bowed, the posterior with a

fine tomentose line down the apical half within: tars?

elongate, slender, pilose and channelled beneath, the joints

of the anterior not imbricated; the first of the posterior

nearly as long as the 3 following united. Body very

elongate-ovate, convex; elytra strongly, and somewhat

reticulately, costate.

I may be wrong in placing this genus near to Nycto-

zotlus, the likeness to that genus not being at all striking.

I think, however, that the form of head, the thickened

edges, and expanded—or broadly guttered—sides of pro-

thorax, the strongly transverse scutellum, the very convex

prosternum, and the broad intercoxal process, warrant me

in so doing. I have but little doubt that the species is

the same as that described by Macleay (Trans. Ent. Soc.

N.S. Wales, 1872, p. 284) under the name of Myctozotlus

elongatulus. To avoid confusion (and as one can never

be quite certain in these matters without absolute com-

parison of specimens), I shall give my species the same

specific title.

350 Mr. F. Bates’s descriptions

Styrus elongatulus, n. sp.?

Elongate-ovate, black witha chocolate tinge, the thickened

edges of prothorax, and costz on elytra, shining: head

coarsely, and slightly reticulately, punctured, impressed

on the crown, front declivous, and furrowed down the

middle; epistomal suture very distinct, broad: prothorax

a little wider (in its widest part) than long,* densely

—except on the guttered margins—punctured, a small

elongate space on the disk smooth ; two shallow fovez at

each side the disk, and a long, transverse shallow impres-

sion near the base: elytra obovate, convex, sinuously con-

tracted and narrowly rounded at apex; each with three

distinct, strongly elevated, slightly undulate coste, crenu-

late at top; these put forth irregular lateral branches,

which ordinarily extend but half across the intervals, and

are sometimes only represented by detached tubercles ; the

suture is also costate, and becomes irregularly bifurcate

before the scutellum: there is also a finer submarginal

costa; the 1st and 3rd cost are united near the apex and

enclose the 2nd; the spaces between these elevated lines

are flat, or slightly concave, and are sparsely studded with

well-defined punctures: legs pitchy ; underside dull black,

distinctly—but finely and not closely—punctured; the

head beneath, and flanks of prothorax, more strongly punc-

tured.

Long 84 lin.; lat. elytr. 34 lin.

Hab.—Queensland. Two examples.

AMPHIANAX, 0. g.

Sides of swbmentum not dentiform: mentum and labium

trapezoidal, convex: palpi wanting: head rather short,

deeply immersed in prothorax, vertex convex: antennary

orbits prominent, projecting laterally beyond the eyes, a

little reflexed, and thickened at the edges; epistoma very

short, front angles slightly bent down and slightly rounded ;

apex broadly emarginate, the sutural line faint at the

middle: labrum strongly transverse, convex, broadly emar-

ginate in front, the hinge broadly visible: eyes large, reni-

form: prothorax: transverse, a little depressed, strongly

arcuate-emarginate—and very finely margined—in front,

broadest behind the middle, broader at base than at apex,

* Macleay gives it as rather longer than wide, and without actual ad-

measuremeut it does appear to be so.

of new genera and species of Tenebrionide. 351

sides well rounded, front angles outwardly curvedly pro-

duced, very prominent, acute; basal angles shorter, acute,

outwardly directed, free; sides a little éxpanded and slightly

attenuated, the edges moderately and almost uniformly

thickened ; base rather strongly bisinuate, broadly lobed

in the middle, finely margined: scutellum convex, mode-

rately transversely and curvilinearly triangular: elytra ~

oblong-oval, but little convex, a little broader at base than

base of prothorax, middle of base subtruncate, slightly

oblique at each side; shoulders feebly rounded, lateral

margins reflexed and slightly canaliculate within; ep7-

pleural fold moderately broad, subhorizontal, entire: legs

moderate, rather slender ; femora compressed, feebly clavi-

form: ¢ibie sublinear, slightly thickened at apex, the pos-

terior with a fine tomentose line within, near the apex,

spurs minute, two to each ; tars? channelled beneath (the

posterior at least), and clothed—as well as the apex of the

tibiz within—with fine golden hairs, first joint of the inter-

mediate nearly as long as the two following united, first

of the posterior longer than the two last : intercoxal process

wide, apex broadly rounded : prosternum full and convex,

its process robust, horizontal, prominent, and rounded

behind: mesosternum subvertical and broadly concave in

front, its epimera posterior: metasternum longer than

ordinary in this group, equalling in length the 2nd ven-

tral segment: 3rd and 4th ventral segments slightly

sinuously emarginate, and broadly coriaceous, behind: an-

tenne—except the first five joints, which are like those in

Onosterrhus—wanting : body oblong-oval, subdepressed,

smooth.

The general form, and the scutellum, approach this genus

to Cilibe, but the form of head, the thickened lateral edges

of prothorax, the bulging prosternum, the broad intercoxal

process, the legs, and the tarsi, are more those of the Ono-

sterrhus group. The metasternum is longer than in any

of the related genera.

Amphianax subcoriaceus, n. sp.

Oblong-oval, subdepressed, black, opaque: head mi-

nutely punctured, a shallow, foveate depression at each

side the front, close to the eye: prothorax not visibly

punctured, a slight oblique impression at each side the

basal lobe: scutellum sparsely, but distinctly punctured :

352 Mr. F. Bates’s descriptions

elytra indistinctly costate, faintly subreticulately wrinkled,

or subalutaceous, sparsely, finely and irregularly punctured,

with a slight indication, at the sides, of a seriate arrange-

ment between the costz ; at the extreme margin the usual

row of close-set punctures, not reaching the apex ; under-

side, and legs, shining black; abdomen finely longitudi-

nally wrinkled, and—together with the legs—minutely

punctulate.

Long. 64 lin. ; lat. elytr. 3 lin.

Hab.— Australia.

AGASTHENES, n. g.

Mentum transverse, anterior angles strongly inflexed,

middle portion large, prominent, transversely subcordiform,

and sulcate down the middle from apex nearly to base :

labium short, strongly transverse, broadly emarginate in

front, angles rounded: palpi wanting: sides of submentum

produced into a very large, angular, prominent tooth:

gula with a deep, longitudinal furrow which becomes faint

and bifurcate behind: head large, subquadrate, immersed

in prothorax nearly to the eyes; front very long, plane,

gradually declivous: antennary orbits long, narrow, pad-

hike (‘* en bourrelet”), subparallel, separated from the front

by a deep, straight groove, extending from the eye to the

anterior border: epistoma short, trapezoidal, front angle

strongly bent down, apex slightly emarginate, the suture

represented by a faint angulate line at each side, and a

slight depression in front of the line, within the angle:

eyes narrowly reniform, projecting beyond the sides of the

antennary orbits: labrum prominent, strongly transverse,

angles rounded, slightly emarginate at the middle of the

anterior border, membranous hinge visible: prothorax

wider than long, arcuate-emarginate in front, front angles

very prominent, acute, directed forward, sides gradually

widened to beyond the middle, suddenly constricted near

the base, hind angles acute, directed outwards, not over-

lapping the shoulders, lateral margins somewhat expanded,

attenuate, the edges strongly thickened, gradually more

feebly so from behind the middle to the hind angles ; base

feebly trisinuate, narrowly margined, apex strongly mar-

gined at each side, not at all in the middle: scutellum

convex, strongly transversely triangular: elytra closely

applied to—and wider than—the base of the prothorax,

elongate, moderately convex, shoulders rounded, sides very

of new genera and species of Tenebrionide. — 353

slightly widened to beyond the middle, thence gradually—

and slightly sinuously—narrowed to the apex, margins

reflexed and slightly canaliculate within, very strongly so

at the shoulders ; at near the middle of the basal margin

there is a short, elevated ridge which seems to be a de-

tached remnant of the prominent, reflexed margin at the

shoulder ; epipleural fold broad, extending to apex: pro-

sternum very full and convex, its process robust, horizontal,

prominent behind: mesosternum vertical in front and

broadly and deeply concave, its epimera posterior: meta-

sternum short: intercoxal process broad, parallel-sided,

apex subtruncate and, in common with the base of the

metathorax, strongly indented; hind -margins of 3rd and

4th ventral segments angularly (at each side) emarginate,

and broadly coriaceous: legs moderate, femora strongly

compressed, attenuate at base; tibie straight, a little

thickened at apex, the anterior with a single spur, the

others with two very small, almost invisible; the hind

tibiz with a faint tomentose line near the apex within:

tarsi wanting : antenne—except the first six joints, which

are absolutely similar to those in Hypocilibe—wanting :

body elongate, moderately convex, smooth.

The genera of the Nyctozoilides—like those of the

Tenebrionides, Cnodalonides and Helopides—are now be-

coming almost unmanageable by reason of the complexity

of their relationship, or affinity, with the genera of other

groups as established by Lacordaire. ‘The present genus

has lost, in feature, every trace of connection with the true

Heleides, its facies being more that of the Calometopides.

The majority of its characters, however, are decidedly

those of the Onosterrhus group, viz., the deeply immersed

head ; the prothorax very strongly emarginate in front,

with broadly guttered sides, and thickened edges; the

short, strongly transverse scutellum, &c. The form of the

head, and the prothorax strongly constricted near the base,

will at once serve to distinguish this genus from Ono-

sterrhus.

Agasthenes Westwoodt, n. sp.

Elongate, black, smooth, opaque ; labrum and antennz

dark chestnut-red: head and sides of prothorax finely and

not closely punctuated ; disk of the latter, and the elytra,

exceedingly minutely (not visibly to the naked eye) punc-

tulate ; elytra having at the extreme margin the usual row

of rather close-set punctures, which do not extend to the

the shoulder to near the apex: underside black ; legs

pitchy-black, shining ; head beneath coarsely punctured ;

underside of the expanded margins of the prothorax finely

transversely wrinkled; prosternal process narrowly rounded

behind, suleate at each side between the coxee, and—together

with the legs and abdomen—punctured, the punctures of

two sizes, the smallest being the most numerous; femora

transversely rugulose; abdomen longitudinally rugose at

each side.

channelled: antennary orbits slightly reflexed, rounded :

epistomal suture well marked, almost semicircular: eyes

large, prominent, transverse, slightly notched in front, not

Near Altes, Pascoe, but at once to be distinguished

from that and from all the other genera of the subfamily

Apomestris Westwoodi, u. sp.

Somewhat broadly ovate, convex ; body and legs covered

Decialma ? Pascoet, n. sp.

joints 9—10 of the antenne are fully as long—if not

longer—as broad ; neither does it any better accord with

Erichson’s genus Olisthena.

Mithippia Jansoni, n. sp.

This species differs from Pascoe’s aurita (Ann. Mag.

Nat. Hist. 1869, p. 293) in having the elytra covered

with rounded punctures—more or less confluent by irre-

gular transverse wrinkles—without the slightest trace of a

regular linear arrangement, and by being entirely destitute

of hairs.

the greatest convexity behind the middle, broader at base

than base of prothorax ; sides strongly margined, reflexed

and canaliculate ; epipleural fold somewhat abruptly termi-

nated at the 4th ventral suture: prosternum a little pro-

duced in front, compressed but not carinate, the process

without hairs.

The genera of this subfamily are now becoming very

numerous, especially having regard to the small number of

the species. I can see no help for it. The present genus

possesses a combination of characters, and a facies, that

will not allow of its being included in any of the previously

described genera.

Ctimene Breweri, un. sp.

Elongate-oval; entirely of a deep, rich brown, glossy :

head and prothorax finely, regularly, and somewhat closely

punctured, an obscure fovea on the latter at each side the

This species would seem, from description and figure, to

approach . erebea, Pascoe: but it is twice as large, and

the elytral sculpture is different.

Ectyche sculpturata, n. sp.

depressed, and much more sparsely clothed above with

hairs than the preceding: prothorax transverse, scarcely

convex, sometimes faintly depressed down the median

line, feebly emarginate in front, sides moderately rounded,

emargination of hind angles strong, and with an acute

tooth at the centre; finely and densely (as well as the

head) cellulose-punctate, the punctures much smaller and

dentiform, seriate-punctate, the punctures rather large,

round, approximate; intervals flat, at dottom minutely

intricately rugulose, studded with very small, flattened

tubercles, each having a small rounded puncture at their

apex behind, the sutural and each alternate interval

appearing brighter (less opaque) than the others: tibiz

normal: underside, legs, antennz, and palpi, pitchy-brown,

shining ; flanks of prothorax rather closely reticulate-pli-

cate; breasts sparsely pilose; antennz rather long, stouter

Oblong-oyvate, black, subopaque, pilose: head and _ pro-

thorax punctured as in the preceding, but somewhat more

confusedly so; prothorax relatively narrower, much more

convex, scarcely emarginate in front, sides well rounded,

emargination of hind angles less deep, and the central

tooth less acute, than in the preceding: elytra slightly

shining, base truncate, shoulders rounded, seriate-punctate,

intervals flat, sparsely and finely muricate-punctate, each

with a row of conical tubercles, which become much larger

and closer at the sides and apex, each tubercle with a

rounded puncture at apex; the sutural and each alternate

interval more shining than the others: apex of the tibize

MIcCRECTYCHE, n. g.

Antenne short, compact, not perfoliate; joint 3 ordi-

narily larger than 4; 4—7 subequal—or very gradually a

little shorter and wider—obconic; 8—10 stouter, gra-

dually transverse, subtriangulate; 11 large, briefly oval,

or globular: epistomal suture obsolete: prothorax with a

more or less distinct flattened margin, usually feebly

erenulate at the edges; emargination of the basal angle

generally very strong, and with a prominent, acute tooth

in the centre; or, it may be said, there is a more or less

deep, rounded excision in front of the hind angle, the

angle itself being acutely dentiform, and the margin

behind leading a little sinuously to the base, which is more

or less broadly rounded: humeral angles of elytra more or

less strongly dentiform: tébie@ short, straight (except in

intermedia), robust; the anterior triangular, their inner

edge ordinarily straight throughout, their outer edge

(except in intermedia) unspined, their apex not obliquely

truncated, but produced outwardly into a strong, bifid

tooth: prosternum not abruptly elevated; mesosternum

strongly declivous in front. Species of small size, rather

robust, pilose.

Very near Eectyche, but distinct by the characters

indicated, and by the form of the antenn@ especially. It

is probable the Ectyche? nana, Pascoe, may belong to

this genus.

As regards the three species, and one supposed variety,

of this genus, described below, they are sufficiently close

_ of new genera and species of Tenebrionide. 363

to each other to make it possible that a large series of

specimens, and the discovery of the sexual characters,

would reduce them to two species, by the linking of ferru-

ginea and its supposed var. to intermedia as a sex.

In M. intermedia there is a decided leaning towards

Ectyche in the form of the pro- and meso-tibiz. We have

previously seen that the tibiz are not of the normal form

in Ectyche tuberculipennis. The dentate humeral angle,

which is strong in all the species of the present genus, is

also met with (though in a feebler form) in Ectyche scabri-

pennis. As I have previously observed, the essential

character of the present genus resides in the antenne.

The species of both genera have the head and prothorax

closely, and more or less confluently, cellulose-punctate,

and these punctures (if they can be called such) are, in

the present genus, distinctly ocellate, or have their centre

occupied by an impressed point, from which arises a hair.

I have used the term cellulose-punctate in contradistine-

tion to that (and the most common) style of punctuation,

which consists of impressed points on a more or less

plane surface; such distinction of terms has long been

wanted.

Micrectyche intermedia, n. sp.

Oblong-ovate, pitchy, anterior border of head ferru-

ginous, the rest, and the prothorax, pitchy-ferruginous ;

pilose, the hairs much longest at the sides; moderately

convex: prothorax a little wider than long, convex, faintly

emarginate in front, sides moderately rounded, the margins

distinctly expanded, flattened, of a clear ferrugious; the

prebasal emargination strong, semicircular; base strongly

rounded: elytra a little shining, humeral angle less strongly

dentiform than in any of the following; seriate-punctate ;

intervals punctured, the punctures a little muricate and

transversely confluent, the sutural intervals smoother and

more shining than the others: legs and antennx ferru-

ginous; 3rd joint of the latter scarcely longer than the

4th, the last joint briefly oval: pro- and meso-tibiz slightly

bowed, their apex appearing produced within: pro-tibiz

irregularly spinose at outer edge, the apex slightly obliquely

truncate, the outer apical angle subdentiform.

clouded with black marks; elytra a little shining: much

more robust than the preceding; prothorax broader, the

lateral margins less distinctly expanded, and feebly crenu-

late at the edges, the prebasal emargination feebler and

shallower, the base more gradually and less strongly

rounded ; elytra broader and shorter, more massive; hu-

meral angle strongly dentiform, intervals wider, the -

punctuation better defined, less muricate, less transversely

confluent, the sutural intervals much less _ evidently

pale ferruginous, shining; 3rd joint of antennz decidedly

longer than the 4th, the 11th subglobose: tibiz short,

straight, triangular; the anterior not spinose at outer

edge; inner edge straight throughout; outer apical angle

produced into a strong bifid tooth.

intervals more coarsely sculptured: prosternum between

the coxe a little broader and longitudinally concave.

Long. 14 lin. .

Hab. ; —Champion Bay. One example.

The general form of this var.? is more like that of

M. intermedia, but the tibize are differently formed; the

3rd joint of the antennz is decidedly longer than the 4th,

the lateral margins of prothorax are much less distinctly

expanded, the base less strongly and more gradually

rounded, and the colour is entirely dull ferruginous ; ; inall

these respects it agrees more closely with M. ferruginea.

A knowledge of the sexual character would determine

to which, if to either, this var.? belongs, and also whether

both it and M. ferruginea are really and specifically dis-

tinct from intermedia ; at present I am compelled to hold

them so.

Micrectyche Ryet, n. sp.

Elongate-oval, slightly depressed ; pilose ; dilute pitchy-

ferruginous; prothorax clouded with black marks, less

convex, and less strongly rounded at the sides posteriorly,

than in the preceding ; the lateral expanded margin feeble,

the prebasal emargination lunate, the base slightly and

of new genera and species of Tenebrionide. 365

eradually rounded: elytra more elongate, less convex,

less robust, the rows of punctures larger, more distinct,

the punctuation on the intervals less confused, than in the

preceding: legs and antennz ferruginous; 3rd joint of the

latter much longer than the 4th; the 11th subglobose.

Long. 2 lin.

By its more elongate, more parallel and less convex

no doubt as to this being specifically distinct from all the

preceding.

Adelium (Seirotrana) strigipenne, n. sp.

Oblong-oval, flattish above, black, shining; sparsely

and indistinctly —save on the head—pubescent: head

coarsely and reticulately rugose-punctate, the punctures

oblong, front not excavated ; 3rd joint of antennz a little

shorter than 3—4 united; antennary orbits rounded (not

angulate) at the sides; prothorax transverse, the anterior

angles less acute than in catenulatum, and directed towards

the lateral margins of the head; the sides much less

strongly incurved behind the middle—the base is conse-

quently considerably wider than the apex, the margins

toothed only from the middle to the base, the punctuation

is more confluent, the punctures often very elongate ;

median dorsal furrow faintly marked, the fovea at each

side the disk much fainter, the median basal one obsolete :

scutellum smooth: elytra subparallel to two-thirds their

length, shoulders narrowly rounded; each elytron with

10 narrow, feebly elevated, slightly waved (both laterally

and vertically) coste, which are crenately punctured at

each side, and often also (especially the sutural) at top; the

intervals are very feebly bicostate, or trisulcate, the inner

sulcus the most marked, and frequently interrupted by the

confluence of the two secondary (or intermediate) costa,

which are also waved like the primary costee; when viewed

from above the elytra appear to be irregularly transversely

tuberculate; when viewed from the side they have a finely

rippled appearance: underside, legs, and antenne, black.

head rugosely punctured: prothorax ample, convex, regu-

base closely applied to base of elytra, rather strongly tri-

sinuate, distinctly bilobed in the middle; hind angles

slightly rounded, a little outwardly directed ; median

dorsal furrow well marked at base, absent at apex; some-

what finely and irregularly punctured and rugose; a dis-

tinct oblong impression at each side near the middle of

the margin, and another impression at each side the base

at the outer sinus: elytra subdepressed, scarcely wider at

base than base of prothorax; sides gradually narrowed

from before the middle to the apex; each elytron with 9

well-marked strie, which are minutely and _ indistinctly

punctured ; intervals smooth, impunctate, subconvex

exclosed by the 3rd and 5th and 7th and 9th; the 3rd and

7th extend to—and unite at—the margin, just before the

apex; epipleural fold normal: underside and legs bronze-

black, shining; the former almost impunctate ; the latter

rather robust, feebly punctured, sparsely pilose: antennze

stout, very gradually thicker outwardly; 3rd joint as long

as 3—4 united; last joint elongate, ovoid: prosternal

process horizontal, strongly and acutely produced behind :

mesosternum prominent, broadly concave throughout its

length: intercoxal process very wide; apex squarely trun-

cated: last joint of antennze, and the tarsi, fulvous.

Hab.—New Caledonia. One example.

By the form of the prosternal process, mesosternum, and

the trisinuate base of prothorax, the present species will

form the type of a new section of the genus. The pro-

thorax is disproportionately large. It might well be the

Adelium exul of Montrouzier; but he gives eight striz only

to each elytron, the intervals as slightly rugose, and the

legs as “ presque gréles.”

carinate—irregularly confluently punctured, longitudinally

rugose, the punctures and the rugosities together having

somewhat of a chain-like appearance when viewed laterally

and obliquely ; the 4th interval is expanded near the base

and has thereon an impressed elongate-oval ring; the sides

and apical half of the elytra are also irregularly, undulately

secure, subopaque ; prothorax less distinctly attenuate at

margins, the edges not distinctly crenulated, the sides more

or less parallel at the hind angles, the base still more feebly

trisinuate, the smooth discal spaces more distinct; the

elytra are of the same form, but the longitudinal furrows

Long. 4 to 44 lin.; lat. elytr. 13 to 1? lin.

Hab.—New Caledonia. ‘Three examples (1¢, 2 ? ).

Dystalica* subpubescens, n. sp.

Of a similar form, colour, &c. to D. homogenea, Pasc.,

but smaller, the head and prothorax less densely, and not

nearly so coarsely, rugose-punctate ; the latter also more

regularly rounded at the sides, the lateral margins finely

reflexed, but not at all crenate; the stri of the elytra less

strongly and less coarsely rugose-punctured, or crenated,

the intervals a little narrower, and, especially at the sides,

more sharply convex or careniform.

In both species the intervals of the elytra are sparsely

but rather coarsely punctured, and have, at their apex, a

short row of small, conical, black tubercles; the entire sur-

immersed in prothorax, not—or but little—inclined, tra-

peziform in front: epéstoma elongate, completely hiding

the labrum, the apex feebly emarginate, the angles rounded:

transverse (but much less strongly so than in Isopus), 11

large, subovoid: prothorax subquadrate, very moderately

convex, sides subparallel, incurved at apex, rather strongly

margined and a little canaliculate within, apex feebly emar-

ginate, front angles not produced, narrowly rounded ; base

rounded in the middle, hind angles somewhat obtuse, nearly

forming right angles: scute/lum minute, triangular: elytra

wider—and subsinuously emarginate—at base than base of

prothorax, strongly margined | at the sides, reflexed, and

canaliculate within: pr osternum not bulged out from the

Near Isopus, but at once to be distinguished by the

form oblong-oval, and much less convex; the subquadrate

prothorax feebly emarginate in front, the apical angles not

prominent; the presence ofa scutellum ; the different pro-

sternum ; the narrower, oval intercoxal process, &c.

From Pseudhelops it may be known by the longer head

(especially the epistoma), the concealed labrum ; the more

strongly expanded and depressed outer joints of the

antenne; the differently formed prothorax—the sides

of new genera and species of Tenebrionide. 371

more strongly margined ; the prosternal process produced

and lanceolate behind, &c.

Metisopus purpureipennis, n. sp.

Oblong-oval, moderately convex ; head—save the ante-

rior margin, which is reddish-brown — black, finely and

not closely punctured ; prothorax glossy black, finely punc-

tured, a small foveate depression—more or less marked—

at each side the middle at the base; elytra deep purple,

the suture reflecting metallic green, glossy; each elytron

antenne dark chestnut-brown, shining.

Long. 44 lin. ; lat. elytr. 2 to 2} ln.

Hab.—Norfolk Island. ‘Two examples.

In one of these examples the prothorax is distinctly

longer, and the elytra broader, than in the other,—possibly

sexual differences.

CHLOROCAMMA, n. g.

This genus is near to Jsopus: mentum convex and tri-

carinate in the middle: head deeply immersed in prothorax,

inclined, labrum nearly entirely concealed, epistomal suture

well marked: prothorazx convex, sides finely margined,

gradually curvedly narrowed from base to apex; apex

arcuate-emarginate, front angles not produced ; base dis-

tinctly bisinuate: scutellum triangular, very distinct, much

larger than in Metisopus or Episopus: elytra more or less

strongly narrowed from about the middle to the apex,

which is a little produced and narrowly rounded; pro-

sternum a little convex—but scarcely compressed—before

the coxe; the process horizontal, produced and pointed

behind, more or less strongly longitudinally concave or

excavated: mesosternum subvertical in front and broadly

and deeply excavated to the base: metasternum between

the coxz not equalling in length the 2nd ventral segment:

intercoxal process somewhat narrowly oval: legs short,

robust, tibiz nearly straight ; 1st joint of hind tarsi as long

as the two following united: antenne as in Isopus: body

oval, or oblong-oval (according to sex?); the alternate

intervals of the elytra strongly compressed—carinate—

behind.

The Neomida sulcata (elongata), Montrouzier (sec. Coll.

Doué), will enter into this genus.

Chlorocamma carenipennis, n. sp.

Larger than Suleata, Montr.: head black, epistoma

more closely punctured, front densely, reticulately rugose-

punctate ; prothorax greenish-black and moderately shin-

ing —or metallie— green, with pale purplish reflections, and

more or less closely punctured, according to the sex?:

scutellum shining black ; elytra deeply striated, or sulcated,

the striz distinctly punctured at bottom; intervals dis-

tinctly punctured, convex—strongly so at sides and apex ;

the 3rd, 5th and 7th are most strongly and distinctly cari-

nate behind ; the 3rd curves inwards to the extreme apex

and entloses the Ist and 2nd; the 5th and 7th unite be-

hind, and enclose the 6th; sometimes the 4th and 7th and

5th and 6th appear to be united in pairs behind ; the colour

is of a dark green, shining, the base and suture purple ;

underside deep shining black, with slight metallic reflec-

tions on the metasternum and abdomen; flanks of prothorax

more or less coarsely rugose-punctate 5

pro- and meso-sterna, prosternal process, and base of meta-

sternum, coarsely and closely rugose-punctate ; underside

deep shining black; legs pitchy ; antenne, palpi and tarsi

ferruginous.

Long. 41 lin.; lat. elytr. 1? to 14 lin.

Hab.—New Caledonia. Two examples.

In both the present species and in C. sulcata the form

that I take to be the 9g is more broadly oval; the pro-

thorax distinctly wider, more brightly coloured, and more

finely and sparsely punctured.

The present species may at once be distinguished from

sulcata by the larger size, and the head * densely and

reticulately rugose-punctate on the front.

EPIsOPUuS, n. g.

Very near to Isopus, but of a more regularly oval and

much less cenvex form; legs a little shorter and stouter,

tibix more thickened outwardly and more compressed ;

eyes smaller ; scutellum small but very distinct, triangular;

of new genera and species of Tenebrionide. 373

prothorax and elytra more strongly margined at the sides ;

prosternum less compressed in front, the process broadly

rounded behind, convex throughout.

The presence of a scutellum, and the convex prosternal

process will serve at once to distinguish this genus from

Isopus.

The Jsopus convexus, Montrouzier, will enter into this

genus; the species are not unlike, in form and appearance,

to some of the shining-black species of Colymbetes.

Episopus politus, n. sp.

Larger than EF. converus, Montr., moderately convex,

entirely—including legs (except the coxze, which are dark

chestnut) and antenne—of a deep shining black: head

moderately punctured, slightly rugose near the eyes; pro-

thorax minutely and sparsely punctulate, the anterior

angles somewhat produced, acute, directed forwards: scu-

tellum very small, triangular, smooth; elytra feebly seriate-

punctate, obsoletely so at sides and apex; intervals very

minutely and sparsely punctulate, the 7th costiform at the

apex.

Long. 54 lin.; lat. elytr. 22 lin.

Hab.—New Caledonia.. One example.

Distinct from F. converus by the larger size, more pro-

minent anterior angles of prothorax, black antennz, and

smoother intervals of elytra: in #. convexus the intervals—

or rather the whole ground surface—are subcoriaceous.

Isopus.

Montrouz. Ann. France, 1860, p. 299.

The very brief and unsatisfactory exposition of this

genus given by Montrouzier (which might well apply to

a hundred other genera) has determined me to give a de-

tailed description: the possession of typical examples of

the genus out of the Collection Doué enables me to do this,

whilst a further supply of specimens from New Caledonia

has also enabled me to add several new species. The

position of the genus is undoubtedly with the Ist section

of the Misolampides of Lacordaire,* and it must be placed

immediately after my genus E’pisopus, this latter having—

* Gemminger and V. Harold in their Catalogue-have placed it—hap-

hazard—with the Strongyliides.

374 Mr. F. Bates’s descriptions

in common with Chlorocamma, Metisopus and Pseudhelops

—a scutellum.

Mentum trapeziform, sides in front inflexed, middle por-

tion prominent, tricarinate, the two lateral carinze oblique:

mandibles bifid at apex : last joint labial palpi subcylindric,

the apex broadly truncated ; that of the mazillaries securi-

form: head inclined, rather deeply immersed in the pro-

thorax, usually trapezoidal in front; the epistoma long—

nearly entirely concealing the labrum—apex broadly but

not deeply emarginate, the angles sometimes depressed and

rounded, in which case the head appears broadly rounded

in front: vertex convex; epistomal suture more or less

distinct: eyes moderate, or rather small, emarginate in

front, transverse, more prominent laterally than the sides

of the antennary orbits: antenne rather short, joint 3

elongate, 7—10 gradually transverse, 11 large, rounded at

apex: prothorax more or less strongly transverse, sides

finely margined, ordinarily gradually, and slightly curvedly,

narrowed from base to apex; apex strongly emarginate,

anterior angles more or less produced, acute, usually

directed forwards, base feebly sinuous, more prominent at

the middle than the angles: scutellum nil: elytra usually

very convex, the greatest convexity before the middle,

more or less strongly narrowed behind, the apex produced

and narrowly rounded; base slightly sinuate-truncate, and

slightly broader than base of prothorax, to which it is

closely applied: epipleural fold broad, more or less

abruptly terminated before the apex: prosternum bulged

out in the middle and very convex, compressed (the head

consequently fits rather loosely in the cavity) ; the process

very broad, robust, horizontal, strongly concave above,

produced behind, the end broadly triangulate or rounded :

mesosternum more or less prominent, broad, horizontal,

vertical in front, and broadly and more or less angularly

and deeply emarginated for the reception of the prosternal

process, the base usually strongly arcuate-emarginate :

metasternum between the cox as long as (sometimes a

little longer) the 2nd ventral segment: intercoxal process

very wide, the apex broadly, and somewhat sinuously,

rounded, or triangulate: legs rather short and robust,

anterior coxe globular, femora thickened in the middle,

compressed; tibiz a little arched, slightly thickened out-

wardly: 1st joint of hind tarsi as long as the two following

united, the last long in all: body very convex, more or less

briefly oval, and attenuate at hind extremity.

of new genera and species of Tenebrionide. 375

The Isopus converus, Montrouz., having a scutellum,

belongs to a distinct genus, as we have previously indi-

cated.

Isopus Blanchardi, Montrouz., 1. c. p. 299

(sec. Coll. Doué).

An example of this species obtained from the Coll. Doué

agrees tolerably well with the rather queer description

given by Montrouzier. The form is somewhat briefly

oval, shining, head and prothorax olive-green, epistoma

and vertex closely punctured, front coarsely and closely

rugose-punctured: epistomal suture distinct: prothorax

somewhat finely and regularly, but not closely, punc-

tured, transverse, wider at base than at apex, sides a little

rounded at the middle, curvedly contracted—most strongly

at apex—at base and apex, front angles acutely produeed

and outwardly directed: elytra very convex, of a beautiful

purplish-violet, the suture broadly greenish, feebly rounded

at the sides to beyond the middle, thence narrowed to the

apex, which is produced and narrowly rounded; base

slightly sinuously emarginate, decidedly wider than base of

prothorax ; on each elytron eight faint—save at the sides—

punctured striz, the punctures small and distant at the

sides and apex, intervals finely and not closely punctured,

flat except the 7th, 8th and 9th, which are feebly costiform

(the 7th most distinctly so) from near the apex: prosternal

process broadly rounded behind: mesosternum short, but

little prominent, broadly excavated nearly to the base:

underside and legs shining black, with a greenish tinge ;

antennee and palpi pitchy: intercoxal process moderately

wide, broadly and slightly sinuously rounded at apex.

Long. 43 lin. ; lat. elytr. 2 lin.

Hab.—New Caledonia.

Isopus robustus, n. sp.

Very briefly oval, shining, head and prothorax shining

black, the former coarsely and closely rugose-punctate on

the front; the latter very convex, the sides gradually

narrowing in a slight curve from base to apex; apex

strongly emarginate, front angles acutely produced and

directed forwards, disk foveate-punctate, sides and apex

very finely punctured: elytra scarcely wider at base than

base of prothorax, sides more or less gradually narrowed

from the middle, the apex produced and narrowly rounded,

376 Mr. F. Bates’s descriptions

bronzy-green with the base violet, or purplish-violet, and

the suture more or less broadly dark green, punctate-

striate, the striz very faint even at the sides, the punc-

tures minute at the sides, obsolete at the apex; intervals

minutely punctulate, flat, the 7th only feebly convex at

the extreme apex: underside and legs shining pitchy-

black, palpi and antenne dark chestnut-red: prosternal

process broadly triangulate behind: mesosternum very

prominent, broadly and somewhat angularly notched in

front, and produced at each side: intercoxal process wide,

apex very broadly triangulate.

Long. 44 to 44 lin. ; lat. elytr. 23 to 23 lin.

Hab.—New Caledonia. Three examples.

Var. Smaller. Long. 3}to3}ln. Disk of prothorax

slightly rugulose.

alab.— New Caledonia. Two examples.

This species is easily to be distinguished from all the

others by the disk of the prothorax foveate-punctate. I have

received it from Paris, and have also examples out of the

Coll. Doué, as the J. convexus, Montrouz., but this is

manifestly wrong, his description clearly gives the whole

surface of a brilliant black, and as having a scutellum.

Isopus Allardi, n. sp.

Briefly oval, shining, head and prothorax dark olive

green, elytra purplish-violet with slight greenish reflections,

the basal half of the suture green: head above entirely

finely and not closely punctured: prothorax moderately

convex, feebly depressed at the middle of the base, sides

eradually, and scarcely curvedly, narrowed from base to

apex, apex strongly emarginate, the angles acutely pro-

duced and directed forwards; moderately punctured on the

disk, the punctures near the base a little larger (but by no

means foveate) and more scattered, those on the sides very

minute: elytra very convex, but more gradually declivous

behind than in those preceding, but little wider at base

than base of prothorax, sides gradually narrowed from

before the middle to the apex, which is strongly produced

and very narrowly rounded; punctate-striate, the striz

more distinct than in robustus; the 7th, 8th and 9th in-

tervals as in Blanchardi: underside and legs very glossy,

pitchy-black with a slight greenish tinge on the meta-

sternum and abdomen: cox and palpi glossy light chest-

nut-red, basal joints of antenne and tarsi a little darker:

of new genera and species of Tenebrionide. 377

prosternal process and mesosternum as in robustus : inter-

coxal process very wide, the apex distinctly oe trian-

gulate.

Long. 4 lin.; lat. elytr. 24 lin.

Hab.— New Caledonia. One example.

Distinct from Blanchardi by the form of prothorax, &c.,

and from robustus by the punctuation on the disk of pro-

thorax not foveate, &c.

Lsopus cyaneus, 0. sp.

Somewhat briefly oval, shining, cyaneous with a slight

violet tinge, the prothorax a little lighter: head and pro-

thorax finely punctured, the epistoma and sides of the

latter minutely so; epistomal suture distinctly marked and

somewhat angulate at each side: prothorax relatively wider

and shorter than in those preceding, sides slightly curvedly

narrowed from base to apex, the anterior angles scarcely

so strongly and acutely produced as in those preceding, and

directed towards the lateral margins of the head, very dis-

tinctly depressed at the middle of the base: elytra of the

same form as in Allardi, but still more gradually declivous

behind, the apex scarcely so strongly produced and a little

more broadly rounded, the punctuation of the striz stronger

than in those preceding, especially at the apex, where it is

the strongest: intervals indistinctly punctulate, the whole

of them more or less convex at the apex; the 9th is costate

from near the shoulder to its junction with the 8th, which

is costate from before the middle to its junction with the

7th near the apex, and the 7th is strongly costate from the

middle to the extreme apex of the elytra ; underside blue

with a greenish tinge on the metasternum and middle of

abdomen, shining ; prosternal process, mesosternum, and

legs, shining black; the two former, and the intercoxal

process, of same form as in Adlardi: tarsi and basal joints

of antenne pitchy brown.

Long. 44 lin.; lat. elytr. 24 lin.

Hab.—New Caledonia. One example.

Easily to be separated from all the other species by the

colour, the strongly punctured striz at apex of elytra, and

the outer intervals strongly compressed, costate.

Isopus caledonicus, n. sp.

Oval, a little less convex than any of the preceding:

head and prothorax shining black : front slightly depressed,

378 Mr. F. Bates’s descriptions

somewhat closely, but not coarsely, rugose-punctate ; epi-

stoma and vertex minutely punctate: prothorax of same

form as in cyaneus, the anterior angles a little less pro-

duced, disk somewhat sparsely punctured; the punctuation

on the depressed basal portion sometimes obsolete, sides

minutely and not closely punctulate: elytra blue-black,

with faint violet reflections, decidedly less convex than in

any preceding, the striz nearly obsolete, the punctures

distinct and well marked, except at the apex, where they

are much smaller; intervals distinctly but sparsely punc-

tulate, the 7th only distinctly convex from near the apex:

underside and legs deep shining black ; basal joints of the

antennz and of the tarsi dark chestnut, the palpi paler:

prosternal process and mesosternum as in cyaneus; the

intercoxal process relatively narrower, broadly triangulate

at apex.

Long. 3? to 4 lin. ; lat. elytr. 14 to 2 lin.

Hab.—New Caledonia. Two examples.

Isopus oxygaster, Montrouzier, |. ¢., p. 300

(sec. Coll. Doué).

I have grave doubts as to the wisdom of leaving this

species in the genus Jsopus: the form is globulous and ex-

ceedingly convex, the head and prothorax, and the elytra

behind, being strongly and almost equally declivous, with

the apex of the latter a little produced ; the prothorax is

strongly narrowed to the apex, where it rather closely

embraces the sides of the head, the front angles are pro-

duced, acute and directed forwards; the head is faintly

and distantly punctured, the epistomal suture distinctly

marked ; the prothorax is impunctate, smooth, the base

broadly rounded; the elytra are not wider at base than

the base of the prothorax, impunctate, the striz being

represented by faint lines or streaks, the position of the

7th interval is indicated by a costiform elevation at the

apex; the prosternum is short, compressed and subcarinate

in front, the process is very wide, bi-impressed, and broadly

rounded behind ; the mesosternum is wide, short, broadly

and angularly cleft in front nearly to the base ; the meta-

sternum is rather long, being nearly twice as long between

the coxz as the 2nd ventral segment; the intercoxal

process is very wide, the apex broadly and sinuously

rounded ; the head, prothorax, underside, and femora,

are deep shining black, the elytra are shining black with

of new genera and species of Tenebrionide. 379

a faint greenish tinge; the antenne (entirely), palpi, tarsi

and coxz are ferruginous, the tibiz darker.

Hab.—New Caledonia. One example, obtained from

the Collection of Doué.

Omolipus* oblongus, n. sp.

Elongate-oval, or subcylindric ; above dark green with

a chalybeate tinge, moderately shining, head and pro-

thorax a little duller and darker: epistoma finely and

rather closely punctured; head and prothorax almost

impunctate, smooth ; prothorax very convex, the middle

of the anterior border produced (almost gibbous), front

angles strongly bent down and totally invisible when

viewed from above, the sides strongly rounded to the

base, hind angles obscure: scutellum transversely trian-

gular, finely punctured: elytra elongate, subcylindric,

subparallel, gradually narrowed from near the apex,

which is narrowly rounded; very finely striated, almost

ohsoletely so on the disk, the striz sharply and rather

distantly impressed with narrow, oblong punctures, much

smaller and finer at the apex; intervals rather broad, flat,

impunctate: underside dark green with chalybeate reflec-

tions, shining ; abdomen minutely punctured ; legs pitchy

brown, rather closely punctured ; antenne paler.

ample, captured by M. Duboulay.

Kasily to be distinguished from all the other described

species by the colour, and the subparallel elytra. From

O. cyaneus, Pasc.— the only other species not entirely

black—it is very distinct by its larger size, different

colour, less metallic surface, and differently formed and

sculptured elytra.

Omolipus parvus, 0. sp.

Small, narrowly elongate-oval, shining black: head

subvertical, finely and not closely (except on the epistoma)

punctured ; prothorax similar in form to the preceding

species, but the middle of the anterior border is still

more strongly produced, the anterior angles not quite so

* Pascoe, Journ. of Entom. i. p. 127.

380 Mr. F. Bates’s descriptions, &c.

strongly nor so widely depressed, the sides less strongly

rounded and gradually narrowed from the middle to the

hind angles, and the base is broadly rounded or lobated :

scutellum triangular, pointed behind: elytra rather nar-

rowly ovate, with rows of rather large, oblong, strongly

impressed punctures; underside black, moderately shining ;

abdomen finely and rather closely punctured; legs glossy

black; antennze and tarsi dark chestnut-brown.

Long. 34 lin.

Hab.—Swan River, W. Australia. Two examples.

Judging from description, this species will be very near

to O. gnestoides, Pasc.; but there appear to be sufficient

differences—joined to the widely different locality—to con-

stitute it a good species. :

XV. Notes on the Ephemeride, by Dr. H. A. Hacen;

compiled (with remarks) by the Rey. A. E. Karon,

M.A.

[Read 5th May, 1873.]

| Towarps the middle*of June, 1871, I received from

Dr. Hagen, of Cambridge, Massachusetts, a series of

letters relating to the Ephemeride. They contained much

interesting matter, not only in the form of original obser-

vations, but also in the shape of criticisms and corrections

of my Monograph on the Ephemeride, Part I., which had

been published at the end of the preceding March. They

conveyed information also respecting works which I had

not been able to collate.

The letters from which the notes subjoined are compiled

are four or five in number. They consist, in a large mea-

sure, of transcripts from Dr. Hagen’s note-book, and the

writing of each of them was a day’s work. From this

some idea may be formed of their extent. They are of

a strictly private character. ‘Written off-hand, in haste,

without revision by the author, and with no intention that

they should be published, they were susceptible of some

little condensation, but not of much. The conjecture of

one day was sometimes verified in a subsequent letter, so

that remarks bearing on the same insect are to be found in

more than one place. These scattered remarks it was

advisable to bring together, so as to place the writer’s

views before the reader in the most convenient form. In

order further to facilitate the application to my Monograph

of the criticisms in the letters, I have reduced their mate-

rials into an order corresponding in arrangement with my

work, and have indicated the pages of the Monograph, in

which will be found the passages touched upon in the

Notes.

My own remarks are enclosed in vincula [| ]. Amongst

them I have introduced corrections of errors of printing

in the Monograph, which were not discovered in time to

be inserted with the other corrigenda in the Transactions

for 1871.—A. E. Eaton. |

My collection is only worked out in Ephemera, Palingenia,

Oligoneuria and Cenis. The rest are scarcely at all

studied. It is rather rich in European and North American

species; but in those from other countries it is almost

tabula rasa, containing only some isolated examples.

Most of the specimens are old; some of them, fifty years

or more of age, are not preserved so well as I should like ;

but you know that it is impossible to set old ones, they

would not bear tobe relaxed. . . . I find that I have

separated in my collection 160 species. There are besides

a lot not classified from Central Russia, Siberia, Caucasus,

&c., making in all more than 2,000 specimens. But

some are very bad, and if re-arranged the number of speci-

mens and perhaps of species would be smaller.

A List of the Ephemere of Hungary sent to me by

Frivaldszky gives only the following names: Cenis lactea,

Paling. longicauda, Oligoneuria pallida, Potam. gibbus (?),

P. eneus (2), Cloéon dipterum and another allied species,

a species allied to C. melanonyzx (?), Baetis sulphurea (°?),

cerea, and fluminum (?). The specimens are still in my

collection. A List of the Ephemere of Bavaria still in

my collection sent by Dr. Kriechbaumer gives EF. vulgata,

a few others from Burmeister (1839) and Zetterstedt

(1840). These last two sets have been noticed above in

limited ; perhaps other conclusions respecting them would

be arrived at now.

gigas and affinis, do not belong to insects at all. If you

will compare the figures and descriptions of fossil plants

from the same localities given by Lesquereux in the 4th

at once that the E’phemerites are only parts of leaves of

Hymenophyllites or of Neuropteris. I believe that some

other of the species are similar.

Page 54. Lachlania.—I examined 19 9. They are

not in very good condition ; the eggs in most are either

deposited or just coming out. The ventral segment with

the eggs coming out seems open at the sides. This I have

designated (perhaps improperly ) the egg-valve. ‘The speci-

mens are not in sufficiently good condition to enable one

to be entirely sure about this formation.

[I have examined a 9 Lachlania in Mr. M‘Lachlan’s

collection, and find no trace of an extension of membrane

in the form of an egg-valve, such as may be found in Hepta-

genia. ‘The oviducts are unprotected as in Ephemera. |

Pages 55, 56. I have compared the figures of Olig.

pallida with my type, and believe them to be correct for

the forceps. The forceps is 3-jointed, one long basal and

two short apical joints. The membrane below is rounded

before, and the penis is nearly covered by it. O. Rhenana

has the forceps three-jointed, the penis bifid and con-

siderably longer than the quadrangular membrane below.

In both species the forceps is more membraneous than

corneous. I remark purposely that of both species I have

only one male imago before me, and only one female imago

of O. pallida. In Imhoff's collection in the- Museum, I

found seven ¢ and more 9 subimagines of O. Rhenana,

all alike as to the penis and the membrane below it,

excepting one, which is more similar to O. pallida. ‘ 1 am

not sure that these males are not imagines, the imago

described from Von Heyden’s collection being not at hand

now. ‘Two female imagines from Elberfeld are very

similar to the female O. pallida. Of course new observa-

tions are necessary.

[In August, 1871, I again took Oligoneuria Rhenana

é imago on board a steamer at Cologne. The structure

Notes on the Ephemeride. 391

of its genitalia quite corresponds with the figure in my

Monograph. It is preserved in fluid. I suspect that my

caution respecting dried specimens (Mon. p. 56) was

therefore not altogether misplaced. When I was writing

that caution, I had in my mind the results of some early

investigations of dried specimens, in the course of which

I managed to fabricate two if not three species out of

British and foreign examples of Cents macrura, and I do

not know how many out of Heptagenia elegans, all authen-

ticated by camera lucida drawings of structures! Is it not

natural to be sceptical of drawings made from dried

specimens after that ? |

Page 57. C. latipennis.—Palingenia umbrata, Hag.

Syn., is a Campsurus in very bad condition: perhaps

C. latipennis. ‘The specimen 1s a little smaller than your

dimensions.

Page 58.—Pictet’s Pal. puella is, after the figures,

surely a Polymitarcys and not Campsurus. I believe it

will go with B. alba. B. alba, Say, is a Polymitarcys.

I caught it at Niagara Falls at the end of August, swarm-

ing just like P. virgo, to which species it is closely related,

though distinct. It is undoubtedly Ephoron leukon, Wil-

liamson, from New Jersey. I have a male from N. York,

taken not so very far from Belleville, N. Jersey. The

colour of the abdomen alone would not agree. The type

from Red River is a female, and smaller than some males.

The description of Say has apparently nothing in common

with B. ferrugineus. Of course thisis a matter of opinion.

The reference to snow flakes makes me believe it to be a

Polymitarcys.

[I had not seen a Polymitarcys from America, and was

inclined to suspect that the third seta in Pictet’s figure

was merely an artistic embellishment. With this bias, I

was led to refer P. puella to Campsurus, that it might be

near P. albicans. I.was induced to attach some weight

to Mr. Walsh’s opinion about the relations of B. alba to

B. ferrugineus, from the supposition that he would not

have differed from Dr. Hagen without some good reason.

I entirely concur with Dr. Hagen now. |

even in Hungarian specimens, are in P. fuliginosa dark

coffee-brown, even in specimens nearly seventy years old.

I have had hundreds of P. longicauda in my hands, and

even now in my collection are twenty-seven from Cornelius

species very well.

[In a more recent letter to Mr. Walker, I have suggested

that the four specimens alluded to are not genuine British

insects, but Swiss or Italian examples of /. glaucops,

which were accidentally arranged in some series of English

Ephemeride by somebody or other. I do not know who

gave them to Dr. Hagen. Mr. Walker in reply says of

£. glaucops, “1 think with you that it has been called

British by error.” My guess in my Monograph was based

upon the assumption that there was no doubt as to the

specimens being British. As the matter stands now, I

think that this assumption had better not be made. |

error.

[ What then becomes of my LZ. annulata, of which I

accepted as types a 6 im. in the British Museum, and

another $ im. in M. de Selys-Longchamp’s collection,

both of them said to have been authenticated by Dr. Hagen?

I suspect my fig. 23 (immediately below 23a, b, and ac-

cidentally unnumbered), in which the terminal joint of the

forceps is not represented, having been concealed by the

penultimate joint from the point of view from which the

drawing was made, is the cause of misapprehension. The

proportions of the last two joints are given in 23a. The

forceps in both Z. Taprobanes and L. annulata are very

much alike ; it is the penis which should be taken as the

principal criterion of identity in examining specimens of

Leptophlebia, and of this structure Dr. Hagen makes no

mention. It therefore remains to be seen whether annulaia

should be reduced to a synonym or not. I still suspect

that the species described by Dr. Hagen in 1858 is dis-

tinct from Mr. Walker’s Taprobanes. |

Page 83. Lept. femoralis. I possess $ © imago and

subimago. The tarsi of the hind legs are four-jointed ;

claws alike very small. The forceps, penis and hind

wings are greatly damaged; but with care everything can

be made out. The middle seta is wanting (broken ?) in

all; but I believe the species belongs to this genus.

[ The absence of the middle seta in the Ceylon species

seems to have caused Dr. Hagen a little trouble and hesi-

tation. In my characters of this series of the genus I

have stated that these species usually cast off the inter-

mediate seta. Now and then individual specimens retain

it, but they are scarce. ]

[After 1. femoralis some of the “ Species generis

their belonging to Leptophlebia having been verified by

Dr. Hagen. |

lata is still in my collection; a female subimago, with

posterior tarsi four-articulate.

my conjecture. |

Page 85. Leptophlebia marginata. In May, 1853, I

caught, in a small river near Konigsberg, a very common

nymph, which I think may be referred with certainty to

this species. The living nymphs are dark brown and

polished : in alcohol they easily lose the gills. Roesel, IT.,

xii., 1, 2, seems to figure my larva and subimago. His

observation of the copulation of the subimago seems to be

an error. I still possess the nymph.

viduals possess the remains of only two tails, instead of

three.” It was the colour of the insect which had most to

do with my questioning the reference of this species to

Page 87. Leptophlebia cincta. I believe £. halterata,

Fab., to be a Cents ; and if the descriptions in the dif-

ferent works of Fabricius be carefully compared with one

another, I think my opinion will be established. In the

diagnosis in Sp. Ins., Mant. Ins. and Ent. Syst., it is

expressly stated, that the species has only two wings,

though in Gen. Ins. this was only given in the description.

Fabricius of course considered this to be an important

character. The words “ale magne” in Gen. Ins. are not

afterwards repeated in Ent. Syst. ; and the words “ mar-

gine crassiori nigricanti,” together with the arrangement

of halterata before E. brevicauda, seem to be very agree-

able with the supposition of its beng a Cenis. ‘ Abdo-

mine fusco,” given in Gen. Ins., is a character presented

by dead males only, and is afterwards rightly omitted. °

The “ setze triplo” (Gen. Ins.), or “ quadruplo longiores”

(Ent. Syst.), is applicable only to the male. The citation

from De Geer is apparently erroneous.

[ What led me to refer E. halterata with a query to

Leptophlebia cincta was my giving some importance to

this citation of De Geer. Having accepted this refer-

ence, I felt bound to reconcile the diagnosis of Fabricius

with the species of De Geer. Accordingly I supposed

that either “ alee magn” was equivalent to “ large wings”

(an expression implying the presence of a smaller pair),

or I supposed that Fabricius’ type had lost the posterior

pair (a thing that has often occurred in my own collection,

where Psocide used to provide me with dipterous examples

of L. cincta, and of various sorts of Baétis, ad libitum) ;

and I further assumed, that Fabricius must have counted

the abdominal segments in this instance from tail to head.

If Fabricius’ reference to De Geer is worth nothing, these

suppositions of mine are also of no value, and Dr. Hagen’s

relegation of £. halterata to Cenis is completely substan-

tiated. |

is not Pictet’s species (which is Heptagenia elegans, Curt.)

but another, which is allied to Heptagenia flavipennis,

wanting the bands on the femora. It will have to be re-

named. From the type (¢ im.) of the second of Brauer’s

species, I was able to determine the relations of LZ. meso-

leuca. It has the forceps and adjacent ventral plate very

like those of Z modesta ; but the apical joint is as long as

the second, and each of them is as long as the first. |

Page 93. Cenis macrura (halterata, Fab., Hag.). I

have before me a lot in a phial dry, perhaps more than a

thousand. They are from Rismansfelds, a little bath-place

near the Frisch Haff, where in the gardens the tables are

covered with them in the morning, to the depth of some

inches. Pictet, p. 42, relates nearly the same thing of

his C. lactea. I have specimens from Eastern Prussia,

(KGnigsberg.)

Page 94. Cenis lactea, Pict. (? chironomiformis, Cutt. ).

I possess a lot sent by Bremi “17th June, 1854, very

common on the lake at Ziirich.” This is apparently

Pictet’s species, and I had it with me in London, but none

of the specimens in Stephens’ collection agreed with them.

But this is not my halterata, nor the lactea of Burmeister.

I believe that C. chironomiformis, Steph., was 9 of my

halterata [%.e. of macrura. |

Page 95. Cenis dimidiata (lactea, Burm., Hag.; £.

398 Dr. Hagen’s and the Rev. A. E. Eaton’s

plumosa (2 sub.), Miil., Hag.). On the 26th and 27th of

June, 1869, between 6 and 7 P.M. , at the border of a large

pond (Obertisch) near Kénigsberg, this species was ex-

ceedingly abundant. After sunset it disappeared. In a

short time I was covered with subimagines preparing for

metamorphosis. Having sat still a few minutes with ex-

panded wings the subimago exhibited a tremulous motion ;

the skin split along the whole length of the median dorsal

suture of the thorax ; the head appeared; the wings were

going down in the manner of a roof near the abdomen, and

by visible peristaltic motion the abdomen and the sete

were got loose, and by continued efforts and wriggling of

the body from side to side the thorax and wings slowly (in

one minute) came out. The legs until then are kept by

the exuviz quite close to the body, nor can they be ex-

tended before the wings are entirely free and suddenly

erected. As soon as this is effected, the legs take hold of

something and finish the freeing of the abdomen and sete

by walking away from the skin. The insect then flies off

from its seat. The empty skin of the subimago is very

delicate in texture, snow white, and the thorax is gray

with a grayish bundle of crumpled-up wings on each side.

I was unable to find pupa or pupa-skin on the plants in

the water or on the water. As the subimago was of course

just risen, the insect probably undergoes the transforma-

tion from nymph to subimago in the water, like Pal.

longicauda. I pinned several subimagines, and found

that the thorax afterwards underwent the metamorphosis,

and so the specimens are half imago half subimago.

Perhaps this fact may explain some descriptions in the

authors which are not applicable to known living species.

All specimens in a collection with the wings bent down

may be suspected of being in this transition state ; but the

imago sometimes assumes the same posture when pinned.

Concerning the ocelli, Pictet has a very important error.

The two lateral ocelli, shortly stalked, are very near the

oculi (vide Burm. ), just above the base of the antennz, and

not, as in Pict. Ephem. pl. xlii. 2, in the middle of the

front. The anterior ocellus, situated below the margin, is

nearly invisible from above. It is overlooked in every

description that the middle seta is longer than the others,

and that all three of them in subim. ¢ ¢ and imago 2

very soon after the base are pilose and have a stronger

pilosity at the tip. I have specimens from Hungary.

Two males caught after 10 P.M. in another locality are

paler (and so far as I can remember, all specimens caught

late in the night are not so dark in colour), but the fore

femora are darker.

Two males caught at Neuhausen, not far from Pillau,

were sent to me by Prof. Zaddach as luminous insects.

He had seen them in the night giving a small blue light.

[ My own observations of the moulting of the subimago

quite tally with Dr. Hagen’s. I have likewise failed to

find the pupa-skin on the water out of doors. But I

found that the specimens which I reared in the house in

flower-pot saucers, changed from nymph to subimago at

the surface of the water, and left the empty pupa-skin

afloat, just as Baetis or Ephemera does. I had intended

to describe the visual organs in some future part of my

work when treating of the comparative anatomy of the

Ephemeride. Perhaps I may never have time to do this.

In my descriptions I have indicated that the central seta

is not invariably the longest. |

Palingenia. In my paper on the nymph of Cenis (Etn.

found to be very nearly related to Cenis ; but without

knowing the nymph I decided not to remove that genus

from the neighbourhood of the old Palingenia. |

led me to write s for the old italic f and then to

Page 108. Centroptilum luteolum. I do not know

why you have taken Miiller’s &. luteola for this species.

I do not understand the word “ lepidota” used by him; it

is not old Latin; perhaps it means iridescent. Miiller

would not have forgotten to mention the brown tip of the

abdomen ; or he had seen the female only. Your deter-

mination is possible; but that is all that can be said

about it.

[The diagnosis of Miiller’s species is “ E. luteola, lepi-

dota lutea cauda biseta, alis pedibus setisque albis.” From

its position in the book, one would be led to search for the

insect referred to in Pictet’s genus Cloé. Three species of

Cloé, whose females are yellow, occur in Denmark, viz? :—

Cloéon rufulum, Centroptilum luteolum (translucidum,

Pict.) and Baétis binoculatus. Of these the first is dip-

terous, the other two have rudimentary hind wings, those

of the Centroptilum being the smaller. Miiller describes

the male of the Cloéon under the name of EF. rufula,

immediately after the diagnosis of E. luteola. He also

describes the male of the Baetis under the name F. dia-

phana, next but one before the diagnosis of EF. luteola.

He notes of £. rufula, “ Diaphanam refert, at alee minores

null, nec squamule,” which implies that he knew that

Notes on the Ephemeride. 401

diaphana has scale-like hind wings. The word “lepidota”

(Greek for scaly) occupies in the other diagnoses the

position which is held by “ diptera” in the diagnosis of F.

rufula, and therefore no doubt refers to the scale-like hind

wings. . luteola is therefore probably the female of the

Baetis or of the Centroptilum. The words “ pedibus

setisque albis” are more generally applicable to the female

Centroptilum than they are to the female Baetis. |

Page 118. Baetis pumilus. [In June, 1871, near

Ashbourne, in Derbyshire, whilst searching in a very

small streamlet for nymphs of Nemoura (the WN. cinerea of

M‘Lachlan’s Catalogue) at noon, I found a female of B.

pumilus beneath the water depositing her eggs upon the

under surface of a stone, which I turned up. The eggs

were arranged close together in a single layer in the form

of a rounded patch. When she was removed from the

water, her wings erected themselves. Shutting her up

in a box for security I hastened home, and (in about a

quarter of an hour after her first capture) placed the stone,

with her upon it, in a glass jar partly filled with water,

leaving her, without further interference, exposed to the

air. She very soon crept down to the water, and after

feeling it carefully with her anterior legs, walked into it.

As she entered it, her wings once more collapsed, folding

together neatly lengthwise, so as to form a narrow pointed

sheath, which extended over the back of the abdomen as

far as the base of the sete. If I am not mistaken the

setee were placed together side by side. She remained

submerged several hours, quite at her ease, and died in

the following night without returning to the air,—living

live after oviposition if she had never entered the water. |

of H. fluminum & according to Pictet. |

Page 123. Baetis undatus ( fluctuans 9, Walsh, p. 122;

pictus, Etn. p. 122; ferrugineus 6, Walsh, p. 124).—

B. pictus agrees after the description and the neuration of

the hind wing very well with the two types of my Cl. un-

data from New York and the Red River. It also agrees

perfectly well with the male type of Cl. ferrugineus, Walsh,

from Rock Island, Illinois. Two females in Harris’ col-

lection, marked down by Say in his own handwriting as

Baetis descripticostata from Dublin, N. Hampshire, are

the same species. I once compared two types of C. fluc-

tuans, Walsh, and I am now of the opinion that they

belong to the same species. I believe I can see in one of

the hind-wings the short longitudinal nervure not seen by

Walsh. The two females differ in so far as they have

very many fewer cross-veinlets in the fore-wing, especially

near the terminal border and tip. I cannot now find any

other difference, as their general arrangement is the same

(though it would seem to be different by my communi-

cation to Walsh, p. 178). The other females also differ

in the number of the cross-veinlets, but not so much.

One has the border much less coloured with brown. ‘The

peculiar dotting of the body, &c. seems to prove completely

the identity of C. ferrugineus and fluctuans as male and

female of wndatus. I have not seen Pictet’s species. The

figure is a bad one, but the description makes me believe

in its identity with my uwndata, especially as your speci-

mens are from Texas. Of course it is possible that other

similarly coloured species may exist, though none so pecu-

harly marked are known as yet.

[‘The omission of any mention of the dotted marking of

the legs and abdomen in the descriptions previously pub-

lished, led me to fancy that the Texan specimens repre-

sented a new species, for I have not met with any similar

pattern of leg-colouring in any other of the Ephemeride ;

This bar to the union of the four supposed species being

removed, there can be no doubt of their identity with one

another. There is a sexual difference in the neuration of

the wings in Cloéon dipterum, somewhat similar to that

which is presented by Baétis undatus. |

Page 131, foot-note No. 2—consueta. This species

seems to be dipterous, at least some of the specimens do.

A female subimago, however, has hind-wings. I stated I

was doubtful if all of them should be placed together.

Page 136. Heptagenia semicolorata. My Baetis semi-

colorata is not at all your species, and the only one like it

as to the forceps is your vi. 13 of H. fusca. I have before

me several males and females from England. Judging

from the ege-valve of the female (which I do not find

in your work) it is scarcely a Heptagenia even. The

figure vi. 9 is entirely different.

[ With all deference to Dr. Hagen, I still consider my

species and his to be identical. The differences between

his specimens and my figures are due to his examples

being dried specimens, and my drawings being made from

specimens only just dead. Want of space compelled me

to omit the figure of the last ventral plate but one (“ egg-

valve,” Hag.) of the female, which is more deeply excised

than is usual in Heptagenia. I cannot see much pecu-

harity in the nymph as compared with the nymph of

fH. longicauda, venosa or lateralis ; but I do not possess

the nymph of a yellow species such as H/. elegans. There-

fore at present I am disinclined to attach much weight to

the peculiarity of the penultimate ventral plate. In dried

males the lobes of the penis shrink a good deal, and their

junction is concealed beneath by the penultimate ventral

plate. This plate, too, is not then backed up by the fleshy

cushion of integument which, in my figure taken from a

a recent example, is seen to intervene between it and the

penis ; and so the last visible ventral segment in a dried

specimen exhibits only the two triangular lobes which are

seen in my figure beyond the semicircular protuberance of

the belly of the segment. To prevent any chance of a

mistake, I may say distinctly that Stephens’ species is

identical with Curtis’; Dr. Hagen has seen Stephens’

types, and his species is identical with Stephens’; and

I also have compared my types with Stephens’, and find

them likewise identical. |

Page 151. Heptagenia venosa. According to your

figure of the forceps and your description, my species is

identical with yours. Fabricius has in all his four works

the diagnosis of his species in precisely the same words.

In Sp. Ins. he adds the citation from De Geer. The

description of De Geer is long, and contains nothing to

oppose the identification of his species with that of Fabri-

cius, who gives Denmark as a locality. Miiller makes

no mention of the species, unless it be the altogether in-

sufficiently described £. gemmata. Villers names the

species £. nervosa, but does not state why he did this.

Burmeister’s short diagnosis corresponds, if the ‘ subtus

ochracea” is De Geer’s “ subtus grisea ;” only the abdomi-

nal segments ‘basis ochraceis” are not mentioned by

De Geer. The dimensions agree, and Curtis’s B. dispar

Notes on the Ephemeride. 405

is quoted. Pictet cites all the authors mentioned; but

his citation of Burmeister is doubtful on account of his

not having seen the types. But I believe Pictet’s species

to be different from that of Fabricius and De Geer. The

eyes are in Pictet said to be brown; in De Geer sea-green .

the abdomen in Pictet “ fauve,” marked with black; in De

Geer very dark brown, nearly blackish: Pictet “ Les ailes

sont transparentes. . . avec des nervures noires, .

vers l’extrémité de la région costale. . .une teinte

brune ;” De Geer hyaline without colour. Pictet does

not mention the “abdomen subtus griseum.” My type

from Elberfeld is exactly like your H. venosa, though I

believe the ventral lcbe of the last segment in your figure

to be not sufficiently rounded ; I did not give the penis

because it agrees with your vi. 24. The border of the

ventral membrane is more rounded and has only a tubercle

at the side; in my ZH. venosa from Corsica the border is

less rounded and has a tooth at the side; in H. gemmata

the border is nearly straight, and has a triangular lobe at

the side. In the last two the two spines between the lobes

of the penis are wanting; the form of the penis and the

ensiform inferior processes are different. The ventral lobe

of the same segment in the female is also different. I did

not find these species in your Monograph. I believe that

E. maculata, Poda, does not belong here.

[I hardly know whether to attach much importance to

the preceding discrimina, because they are based upon

comparisons of dried specimens; but I give them for

what they may be worth. ‘The figures of the ventral lobes

of the females in particular appear to me to be taken from

distorted examples. Still they might be found of some

use in investigations of dried specimens. The only very

positive and trustworthy distinction mentioned is the colour

of the eyes,—brown in H. venosa, and sea-green in De

XVI. On the habits and economy of certain Hymenopte-

rous Insects which nidificate in briars; and

their Parasites. By Sir SripNey SMITH SAun-

pERS, C.M.G., V. P, Ent. Soc.

[Read 7th July, 1873.]

AT the last meeting of this Society I exhibited a series of

Hymenopterous larvee, lately received from Albania in

their respective briar-cells.

Mr. Smith having kindly undertaken to figure the re-

markable larvee of Raphiglossa and Pszliglossa, as well as

a new genus of Fossorial Hymenoptera, forming a con-

necting link between Mitela and Pison, I avail myself of

this opportunity to supply some details of the habits and

economy of these insects, all reared from briars on pre-

vious occasions, and now brought for exhibition ; including

a fine species of Halticella (one of the Chalcidide), para-

sitic within the larva of Osmia tridentata, as herein

described.

Both these elegant insects, belonging to the family of

the Eumenide, frequent the plains around the Ambracian

Gulf, where they select, in preference to other briars, those

which are upright and soft, growing in moist situations,

which, being exposed to the rain at top, are generally filled

up towards the exterior with two or three inches of earth

to protect the larva cells, these being frequently continued

down to the level of the soil; presenting in some instances

as many as thirteen cells in a single stem.

The adult larvee of Raphiglossa, as awaiting their pupa-

metamorphosis, have already been described by me; *

measuring about two-thirds of an inch in length and one-

sixth of an inch in diameter, of firm fleshy consistency ;

their colour opaque-white; each successive segment pre-

senting an overlapping margin;

and having the posterior margin of each of the abdominal

segments below, vaulted and hollow.

Those of Psiliglossa I had not then observed, and it

may be fitting, therefore, to institute a comparison between

the two. The adult larvie of the latter are nearly of the

same length as the former, but of a pale yellow colour,

broader, somewhat compressed and

= cised but contiguous, and not over-

lapping, nor vaulted and hollow be-

pea neath ; gradually tapering and up-

curved at each end when lying on their back. Not being

cylindrical they do not execute the same gyratory move-

ments as the former. They measure from 15 to 18

millimétres in length, by 4 to 5 in breadth, and from 2 to

3 in thickness ; the smaller ones being those of the upper

cells, which, as usual, produce males. The parts of the

mouth in both these larve are indicated by piceous lines

and patches.

The respective segments, which are very distinctly indi-

cated, may be defined as follows: the five anterior, in-

cluding the head, are compactly welded together and

incapable of separate action in the pseudo-pupa state ; the

3rd, 4th and 5th bearing a spiracle on either side.

The thoracical region terminating here, the two anterior

seoments are assignable to the development of the imago

head, as pointed out by Ratzeburg.t

of certain Hymenopterous Insects. 409

The remaining nine segments appertain to the abdominal

region, whereof seven are furnished with a spiracle on

either side; the last three seements, like the five anterior,

being firmly united together.

By comparing these pseudo-pupz of smallest and largest

dimensions, as well as those occupying the extreme cells

of a long serial sequence (representing males and females),

the number of segments and their conformation as afore-

said are precisely identical. But on the development of

the true pupz, these three conjoined segments give rise to

the additional abdominal segment and bivalved sexual

organs in the male (Burm. § 152); which segments are

wholly absorbed in the corresponding threefold organs

of the female, comprising also the aculeus (1. ¢. § 143).

Thus Shuckard’s remark (in the aforesaid note), “ that

the larve of the males in the aculeate Hymenoptera will

necessarily have an additional segment,” does not coincide

with these results.

The imago Raphiglosse are accustomed to repose for

the night in a very peculiar position, the conditions of rest

being best provided for by affixing their powerful man-

dibles to some rough projecting edge of the briar and then

distending their body and legs horizontally, without other

support than the twisting of the wings lengthwise beneath

the abdomen, which are retained in position by the poste-

rior legs, although even this process is frequently dispensed

with.

This gymnastic feat is accomplished as follows :—After

resting awhile on a projecting snag, the Raphiglossa drew

~ back, laying firmly hold of the snag with its mandibles,

leaving its body and the four posterior legs quite free from

the briar. Then by a rapid movement curving the wings

down longitudinally on either side beneath the abdomen,

and projecting the two posterior legs as it were to retain

the wings thus in ‘position, the tarsi remaining free, and

bending the abdomen downwards, it took up its position

for the night, the intermediate legs remaining suspended,

but the knees of all doubled up close; now and then

raising the abdomen without thereby disturbing the wings,

which remained closely doubled down independently of

such movement. The antennz were laid back on either

side of the head, the mandibles forming the sole means of

support, the forelegs being also doubled up close to the

thorax and the tarsi turned back out of the way ; the body

410 Sir S. S. Saunders on the habits and economy

projected outwards in the form of a crescent. Not unfre-

quently, after fixing the mandibles, a kind of somersault is

performed, whereby the Raphiglossa remains in a hori-

zontal position with the back below and the legs upper-

most, as a favourite posture for repose. One that I sent

alive to Professor Westwood to exhibit its performances,

took up this position of repose for the night ; and another,

which I had subjected to the action of cyanide of potas-

sium in this posture, quietly and unconsciously swooned

away, still holding on in its asphixy and remaining in situ

after death.

Exemplar unicum. In Mus. nostro.

Latreille, in his Genera Crustaceorum et Insectorum

(tom. iv. p. 77, 1809), describes the genus Witela as

having the habitus of a Tachybulus (which he afterwards

identifies with the genus Pison of Spinola, in his Ad-

denda, p. 387), and the wings of a T'rypoxylon, the mar-

ginal cell being however somewhat appendiculated in

Nitela. [

In the present genus the venation of the wings ap-

proximates to that of Pison, the second submarginal cell

being strongly petiolated and receiving both recurrents,

the first of these near the base, and the second rather

beyond the middle of the cell; but, as Shuckard has

pointed out in Pison (Trans. Ent. Soc. Lond. vol. ii.

412 Sir S. S. Saunders on the habits and economy

p- 74), “there is great specific diversity in the form and

size of the second submarginal petiolated cell, as well as

in the mode of its receiving the recurrent nervures; which

are sometimes interstitial, inosculating with the transverse

cubital nervures, and sometimes received within it,” as in

Niteliopsis ; while in his subgenus Pisonitus, “the first

recurrent nervure is received towards the apex of the first

submarginal cell, and the second recurrent about the

middle of the second submarginal cell” (1. c. p. 79).

The antennz however in JViteliopsis correspond with

those of Nitela, having the second, third and following

joints co-equal ; whereas in Pison the second joint is

considerably shorter than the third. In Pison also the

eyes are emarginate, but in Miteliopsis, as in Nitela,

entire. The maxillary and labial palpi also closely cor-

respond in these latter; but the mandibles in Miteliopsis

are simple as in Pison, and not bidentate at the apex, as

those of WVitela.

Thus this genus would seem to form a connecting link

between Pison on the one hand and Mitela on the other ;

whose affinities, in conjunction with Trypoxrylon, had been

recognized by Latreille as aforesaid ; although later writers

have removed the genus Pison from these cognate types,

some to the Nyssonide and others to the Larride.

The pupa-cases of Niteliopsis are of light clay-coloured

material, elongo-ovate, rugose and somewhat brittle ; they

are packed promiscuously amid a quantity of loose refuse

of all kinds brought from without, and the gallery has no

cellular separations.

Those of Nitela are smooth, of a dull carneous tinge,

darkening towards the anal extremity ; they are loosely

placed in separate recesses of the pith, but, so far as I

have noticed, in no regular series. Dr. Giraud, however,

considers their presence in briars as exceptional, stating

that they are more frequently to be met with in the trunks

and branches of decayed trees, although he had also found

their pupa-cases (which he accurately describes*) occu-

pying four consecutive cells in a briar from Fontainebleau.

The transformations of Trypozxylon have been carefully

recorded by Messrs. Dufour and Perris in an interesting

France.*

The Pison Jurinet of Southern Europe also provides

for its progeny in briar-stems, where I have found them

in the pseudo-pupa state, as follows :—

Alyson ater, Spin. Ins. Ligur. tom. ii. fase. 4, p. 253.

Pison Jurine?, ibid., p. 256.

Pupa-cases griseous, rugose, ovate, somewhat brittle, in

serial sequence without intermediate divisions, but partially

connected together and with the excavated gallery by a

scarcely perceptible web corresponding with the puparia

themselves.

On opening one of these cases I found a broad pale-

stramineous curved pseudo-pupa, having the segments

strongly incised, with the head closely bent down to the

centre of the body, where firmly retained and motionless.

The briar in which these puparia were found was com-

pletely excavated to the depth of nine or ten inches, pre-

senting six of the aforesaid dusky cinereous cases smaller

than the gallery itself, but adhering thereto ; one close to

the bottom ; two contiguous to each other after the interval

of an inch; two more also close together an inch above

these; and the sixth half an inch higher. Above these

cells was a thin transverse mud p&rtition, but not at the

extreme top. The puparia, which were similar at each

end, measured about 8 mill. in length by 3 mill. in

diameter.

XVII. List of the species of Galeodides, with description

of anew species in the collection of the British

Museum. By A. G. Buturr, F.L.S., F.Z.S.

[Read 7th July, 1873.]

AN elaborate Memoir on this group was published by

M. Leon Dufour, in the Mémoires de Académie des

Sciences, vol. xvii. pp. 338—446, Paris, 1862, illustrated

by four plates: in this paper the author gave a list (with-

out references) of most of the species previously described,

and conscientiously worked out the structure, both external

and internal, of all the species known to him, from Algeria;

he characterized several new forms, of which he gave care-

ful figures.

1. Mandibles of R. impavida ?

2. Hy » G. orientalis.

3h ua » G. Bengalensis.

3a. Hind leg, with lamellz.

3d. The species, natural size.

In his remarks upon the genus, M. Dufour dissented

from Herr Koch as to the value of the tarsal jomts

as generic characters, and therefore applied the name

Galeodes to the whole of the species; he observed that the

character by which Koch separated the genus Rhax was

fallacious, there -being two claws to all the tarsi: now

TRANS. ENT. SOC. 1873.—PART III. (AUG.) GG.

416 Mr. A. G. Butler’s List of the

Koch’s diagnosis runs as follows :— The tarsi of all the

legs inarticulate ; the tarsal joint short, the terminal joimt

of the palpi hidden.”

M. Dufour characterized the two species Rhax melanus

and R. phalangista thus: —“ all the tarsi with two joints ;”

this character, although it does not agree with that given

by Koch, certainly favours the latter author’s view of the

importance of tarsal characters for the subdivision of the

Galeodide ; M. Dufour also characterized G. brunnipes

and G. guadrigerus thus,— posterior tarsi with eight

joints, intermediate tarsi with six joints:” and G. nigri-

palpis—* posterior tarsi with eight joints, intermediate

tarsi with five joints:” and he believed that if Koch had

known of these species, he would not have attempted to

subdivide the Galeodide as he did.

It appears to me that in a group so extensive as Gale-

odes, and comprising species so similar to one another in

external appearance, it is exceedingly desirable to take

advantage of any constant structural characters for the

formation of genera, and so to reduce as much as possible

the labour of determining the species: that this was Koch’s

view also appears evident from the number of genera

which he formed in his “ Arachniden,” some of them

indeed founded upon characters too slight to be of value ;

I think, therefore, that had he known the species described

by M. Dufour, and seen them to be distinct in structure

from Rhax, Aellopus, Solpuga, Galeodes, and Gluvia, he

would in all probability have added one or two genera for

their reception, and I think he would have been perfectly

justified in so doing.

That Rhaz is a good genus (whatever may be the value

of the others) I have no doubt whatever; not only is the

group distinct to the eye, but the tarsi (according to

M. Dufour) differ in their articulations, and the mandibles

are distinguished by an entirely different character of

dentition; this difference has never before been so well

illustrated as on M. Dufour’s plates, and I consider it a

highly important one, as being easily seen, even in dried

specimens. :

In the present paper I shall adopt provisionally the

whole of Koch’s genera, believing, as I do, that they will

eventually be adopted without hesitation, and fully satisfied

that Rhax, at any rate, will always be considered a good

and well-marked genus.

XVIII. On the Genera of the Cossonide.

By T. Vernon Wottaston, M.A., F.L.S.

[Read 2nd June, 1873. ]

Havine determined during the past winter to examine

critically the structural characters of the various genera

of the Cossonide (so far as accessible) which have hitherto

been published, I soon perceived that a very small pro-

portion of the numerous species which were submitted to

me could by any possibility be embraced by the 29 groups

which were acknowledged by Lacordaire, and which have

been admitted subsequently (with two or thre® additions)

into the Munich catalogue. And moreover the excessive

inaccuracy of the greater number of the diagnoses, as

given by Lacordaire. (—for which however he was not

himself responsible, they having simply been epitomized,

at times perhaps somewhat in haste, from the different

authors by whom they were originally compiled), made it

but too evident that, in order to define them aright, no

asserted peculiarity could be trusted as necessarily true,

but that every single feature would have to be collated

afresh, and on an independent basis. This being the case,

it will at once be seen that my object in the present memoir

has not been to monograph the species; and therefore in

two or three extensive and well-established genera, such as

Cossonus and Rhyncolus, I have been content to select.a

few types, from distant parts of the world, and to treat

them as representing their respective groups. Yet this

very method of proceeding has involved the necessity of

examining at any rate certain species with the utmost

care; and as an accurate list of these will be found at the

close of my paper, it follows that the members of the

family which are there catalogued (amounting to 253)

may be looked upon as arranged systematically zn accord-

ance with my own views.

At the same time I would not intend to imply that no

other representatives of the groups which are more par-

TRANS. ENT. SOC. 1873.—PART IV. (OCT.) ri

428 Mr. T. Vernon Wollaston on the

ticularly extensive have been carefully overhauled,—for -

amongst the Cossoni, for instance, a very large number

have passed under my eye; but since I am not desirous

of undertaking to determine critically their exact specific

titles (which would be rather the work of a separate

monograph), I have thought it safer to leave them wn-

noticed in my general list,—lest a possible misquotation of

the names might result in confusion as regards the nomen-

clature.

To those Coleopterists who have granted me the loan of

their specimens, in this somewhat difficult task, I would

desire to return my warmest thanks. To Mr. Pascoe

and Mr. Fry my acknowledgments are especially due,—

both of whom have, with characteristic liberality, placed

their large and valuable Cossonideous collections at my

entire disposal. It is indeed to the former that I am in-

debted for many of the most remarkable types which I

have been thus enabled to examine,—his series including,

in addition*to some curious modifications from Australia,

a large proportion of the species which were obtained by

Mr. Wallace in the islands of the Malayan Archipelago ;

whilst the rich material of Mr. Fry in the number of its

’ South-American forms stands probably unrivalled. To

Mr. Janson also I must express my peculiar obligations,

the whole of his examples having been generously entrusted

to me without reserve; and my worthy friend John Gray,

Esq., and Dr. Sharp have likewise afforded much valuable

aid in communicating all the members of the family that

they respectively possess. The former in fact owns the

most complete set of Huropean Cossonids with which I am

acquainted; whilst the latter has contributed, amongst

numerous other genera (many of which had been trans-

mitted, lately, by Mr. Lawson, from New Zealand), the

very rare and minute Alaocyba carinulata of Mediter-

ranean latitudes. M. Roelofs, also, of Brussels, has had

the-kindness to send for inspection his unique type of the

Georrhynchus Mortetii, from Monte Video; and I need

not here allude again to the interesting material, amassed

in Japan, of which Mr. G. Lewis has granted me the

loan,—it having formed the subject for a separate enume-

ration in a late~Number of the Entomological Society’s

Transactions.

As regards the method of arrangement, it has been my

endeavour to arrive, so far as is possible, at a natural one.

Had I been content to adopt a purely artificial plan, the

Genera of the Cossonide. 429

various generic characters might have been more easily,

and completely, tabulated ; but since in that case a con-

siderable number of groups which I am satisfied have no

real affinity with each other would have been brought into

juxta-position, I have preferred to sacrifice even convenience

in identification to the more important principle of a cor-

rect adjustment of the several types.* On this account

it is, that while acknowledging the exact number of the

funiculus-joints as of primary signification, I have not

allowed it to over-ride (in a few exceptional instances) a

combination of other features which more than counter-

balance it in structural importance; and hence amongst

the true Cossonides, in which that organ is essentially

7-articulate, I have admitted one genus ( Tetracoptus) in

which the funiculus is composed of four joints, two

(Pentamimus and Tomolips) in which it is made-up of

five, and one (Hexarthrum) in which it consists of six,—

for it would be simply preposterous to include the first of

these amongst the Dryophthorides (with which in other

respects it has absolutely nothing in common), and the

second and third amongst the Pentarthrides, or to asso-

ciate the fourth (which belongs to the sub-Hylastideous,

asperated types) with the anomalous and more or less

fossorial Onycholipides—in which the body is pallid and

somewhat hairy, the tibial hook obsolete, and the tarsi

strictly tetramerous. Moreover Lacordaire has himself

acknowledged this principle by placing Hezarthrum in

the same situation as I have done, namely towards the

close of the subfamily Cossonides ; and it is a method

indeed which is acted upon, more or less, in nearly every

department of the Coleoptera.

With respect to the singular cluster of forms which I have

brought together under the Onycholipides, they might

well be supposed, if viewed per se, to pertain to some totally

distinct (and perhaps as yet undefined) family of the

Rhynchophora; but they are nevertheless so unmistake-

ably connected on the one hand, by means of Halorhyn-

chus and Pentatemnus, with the Pentarthrides, and on the

* Finding it next to impossible in the subfamily Cossonides to tabulate

the characters of more than a small number of the very numerous genera

(whilst, at the same time, adhering to what I believe to be the natural

sequence of the latter), I have, instead, and as a slight assistance towards

the identification, noted a few diagnostic features of each successive group;

and, as a still further aid to the eye, I have cited the particular country to

which the several genera are peculiar, or in which they more especially

predominate.

Bula,

430. Mr. T. Vernon Wollaston on the

other, through Alaocyba, Lipommata, and Styphloderes,

with the Cossonides proper, that it is well-nigh impossible

to doubt (despite their subfossorial habits, 6-jomted funi-

culus, quadriarticulate feet, obsolete tibial hook, and other

eccentricities) that the present family is their natural

location.

Although dissenting from the views of Lacordaire, in

recognizing no par ticular department which is characterized

par excellence, like his Lymantides, by the shortness of

the metasternum (for there is scarcely a single item of the

structure which varies more, according to the exact genus,

and sometimes even according to the species, than the

latter), I have nevertheless not departed greatly from the

method of arrangement which was adopted by him ; and if

there could have been any doubt that the Dryophthorides

constitute an integral portion of the family, it would be

completely dispelled by the existence of such links as

Cherorrhinus and Pentacoptus (the former of which, in-

deed, although, like the latter, manifestly Penkarethradeat:

has actually been cited hitherto, through an unpardonable

error in its original diagnosis, as a Dryophthorid) and still

. more by that wonderful genus Synommatus, from Borneo,

—the distinctive peculiarities of which are so eyenly

balanced between those of the Dryophthorides and Pentar-

thrides that it is by no means easy to decide into which of

the two subfamilies it should be received.

There are six genera, however, of those hitherto pub-

lished, which I have not been able to procure for exami-

nation ; and these therefore (having convinced myself by

experience that recorded characters are seldom completely

to be trusted) I am compelled to leave in doubt,—merely

placing their names between brackets (not altogether un-

accompanied by a few remarks, gleaned from their re-

spective diagnoses) in order to indicate the several positions

which it seems to me not unlikely that they will be found

to occupy. The genera to which I allude are as follows :—

TI.ymantes (from North America), Aparoprion (from the

south of Europe), Oodemas (from Tahiti), Mimus (from

Southern Africa), Portheies (likewise South-African), and

Proéces (from Madagascar). :

Of the twenty-nine groups acknowledged by Lacordaire,

I have rejected Phenomerus,—being satisfied that it is

not truly a member of the Cossonide. Its general facies

and considerably developed prosternum bespeak, I cannot

but think, a much nearer relationship with the Sphadas-

Genera of the Cossonide. 431

mides and Mecopus ; and although the breast is not chan-

nelled for the reception of the rostrum, some of the species

nevertheless have a faint tendency for the slight pectoral

cavity which is very appreciable in Sphadasmus, Mecopus,

&c., and which implies at all events an exceedingly different

situation, in a natural system, to that which is occupied

by the Cossonids. Moreover, the large and robust spine

with which its intermediate tibie are furnished towards

their external apex is quite without precedent in the present

family, and I have had no hesitation therefore in expunging

the genus from our list.

Glancing at the 122 genera embodied in this paper

(75 of which have been treated as new), there are one

or two points to which it may be worth while to draw

attention. ‘Thus, the only groups, outside the anomalous

subfamilies Notiomimetides and Onycholipides, in which

the tibial hook (that almost universal appendage) is

obsolete, are Thaumastophasis, Aorus, Lipancylus, and

Xenocnema (though in Homalozenus it is greatly reduced

in dimensions). And we might perhaps add Amorpho-

cerus to the number, were it not that the tibize in that

genus are eminently spinose at their apex; and it may be

-a question how far the largest of the terminal spines,

although not proceeding from the outer angle, represents

the tibial wncus. Another feature which might be noted,

and which certainly is not in accordance with what I had

originally imagined, is the excessive rarity of anything

approaching to a dentate structure of the femora. The

only group indeed, the truly Cossonideous affinities of

which are beyond a question, i which it is, so far as I am

aware, indicated, is Odontomesites; and even there the

tooth is but obtuse and anguliform, and exists only in the

male sex. It is however more strongly expressed in Notio-

mimetes, Coptorhamphus and Homaloxenus,—all of which,

nevertheless, are, in other respects likewise, abnormal,

their right of location in the present family being possibly

open to dispute. The third peculiarity, concerning which

I would say a few words, is more superficial, and yet, as a

mere aid in the identification, it 1s practically of consider-

able importance : I refer to the extreme scarcity of metallic

tints which is observable amongst the Cossonids. A

brassy lustre, sometimes merging into green, is almost the

only one of which I am cognizant, and even that is re-

markably uncommon. It is conspicuous however (albeit

subject to complete obliteration) in Lamprochrus and

432 Mr. T. Vernon Wollaston on the

Acanthomerus, from St. Helena, in some of the Madeiran

Caulotrupides, and in Oodemas, from the Sandwich

Islands,—a genus which I have not been able to procure

for inspection. We see it also, though much less power-

fully indicated, in the Sericotrogus subenescens from New

Zealand, and in certain of the Phleophagi,—as, for in-

stance, the European P. eneopiceus; and it is about

equally traceable in the Pseudophleophagus tenax, of the

Madeiran and Azorean archipelagos. Except in these

particular instances I have no evidence of its existence; for

in the Pachystylus dimidiatus, from Chili, as well as in

two Pentarthra from the same region, it is so excessively

faint as to be hardly even recognizable. But what I should

regard as far more significant, in a systematic point of

view, is the occasional obsoleteness, or even total absence,

of the scutellum,—for in by far the greater number of the

Cossonids that organ is (in proportion to their size) largely

expressed. In the small subfamilies however of Notiomi-

metides and Dryopthorides, as well as in 13 genera of the

Pentarthrides, 2 of the Onycholipides, and 10 of the true

Cossonides (making 30 groups in all, out of the 122), it

is either altogether untraceable, or else so far reduced in

dimensions as to be detected with difficulty; and it will be

seen by a reference to my tabular synopsis that I have made

use of this fact in locating the particular types to which it

applies.

The curious instability which is indicated amongst the

~ representatives of the present family, in the exact number

of the funiculus joints, is more than paralleled by the

occasional obliteration (whether wholly or in part) of the

organs of sight. The only member however of the true

Cossonides in which the eyes, so far as I am aware, are

absent, is the Lipommata calcaratum,—a pilose, Phleo-

phagus-like Cossonid, of slightly burrowing propensities,

which lives about the roots of sand-plants in the island of

Porto Santo, of the Madeiran archipelago. But in the

anomalous subfamily Onycholipides, no less than three

genera (out of the four)—namely Onycholips, Raymondio-

nymus, and Alaocyba—are totally blind; and the Aus-

tralian Halorhynchus, which (although pertaining to the

latter) is exactly osculant between the Onycholipides and

Pentarthrides, is in a similar condition. And there are

four other Pentarthrideous types—namely Pentatemnus,

Pseudomesoxenus, Amaurorrhinus, and Heteropsis,—as

well as the single exponent of the abnormal subfamily

Genera of the Cossonide. 433

Notiomimetides, in which the visual organs are so far

reduced in dimensions, and so rudimentary in character, as

to be emphatically obsolete.

Into the question of the geographical distribution I need

not now enter, for a glance at the systematic catalogue

will suffice to shew approximately what the ranges are of

the several types. It is curious however to note how large

a proportion of the latter, which have hitherto been brought:

to light, possess insular habitats; and, if we except the

great and almost cosmopolitan genus Cossonus, it would.

seem as if islands afforded conditions more peculiarly .

favourable for the modes of life of the members of the

present family. And this completely accords with my

own experience in the sub- African archipelagos,—no island

appearing to be too minute for the modus vivendi of the

Cossonids. In the Maderian and Canarian groups there

is scarcely any fact more distinctly observable, — where

every detached rock is tenanted by some one represen-

tative, or more, of this particular department. Nor are

trees and shrubs (which seldom flourish in localities thus

weather-beaten and exposed) by any means essential for

their support,—the pithy stems of the ordinary plants

being amply sufficient to sustain them; and I have

frequently found the stalks of dead Thistles and Umbel-

lifere to be perforated through-and-through by their

ravages. In our own country the Cossonids would seem

to play a very insignificant part amongst the Coleopterous

population, only nine members having hitherto been re-

corded; whereas at the Canaries (made up, as they are,

of so many islands and islets) I have myself met with no

less than fourteen, and at the Madeiras (which present a

considerably smaller area) with nineteen; whilst even in

the little island of St. Helena (the geographical base of

which does not exceed that of the Isle of Wight) as many

as fourteen have already been noted, and these I have good

reason to suspect represent but an instalment of its whole

Cossonideous fauna. ‘The British members of our present

family are as follows: — Pentarthrum Huttoni, Woll.

(= Rhyncolus Hervei, Allard); Phleophagus spadiz,

Hbst., and eneopiceus, Bohm. ; Rhopalomesites Tardit,

Curt.; Cossonus ferrugineus, Clairv.; Rhyncolus ater,

Linn. (= chloropus, Fab.), eylindrirostris, Oliv. (= lig-

narius, Mshm.), and gracilis, Rosenh.; and Stereocorynes

truncorum, Germ.

I will merely add that in treating the subject-matter of

the present memoir, it has divided itself into five parts :—

(1) A catalogue of the several groups—arranged syste-

matically, and (so far as I have been able whilst adhering

to what I believe to be their natural sequence) tabulated ;

(2) full generic diagnoses, taken seriatim ;

(3) observations (diagnostic and geographical) on each

separate genus 5

_ (4) brief characters of 139 species which, so far as I am

aware, have not hitherto been recorded ; and

(5) a complete list of the particular members of the

family (amounting, in all, to 253), the structural and

specific features of which I have examined with the greatest.

care, and which may be regarded consequently as the

material from which the paper has been compiled. ;

1. NOTIOMIMETES (nov. gen.).—If the minute insect

(scarcely one line in Jength) from which the details for the

present genus have been compiled, and which I have re-

ceived from Mr. Pascoe as having been captured on the

sea-shore at King George’s Sound in the south of Aus-

tralia, be (as I think, from the structure of its abdomen,

antennze, and general facies, that it is) a veritable member

of the Cossonide, it appears to me to be absolutely neces-

sary to erect a separate subfamily to receive it; for

although in its most significant character of a 4-jointed

funiculus, as well as in its fusiform outline and obsolete

scutellum, it agrees sufficiently with the Dryophthorides,

it is nevertheless so radically different from the exponents

of that section in the fact of its tibie being free from a

terminal hook, in its very widely separated cox (which

are more remote from each other than in any Cossonid

which I have yet seen), and in its pseudotetramerous feet,

that I do not believe it can possibly be associated with

them. Indeed its apically-unarmed tibiz would, in my

opinion, have almost sufficed to exclude it from the Cosso-

nide altogether, was not that particular feature one of the

main characteristics of the subfamily Onycholipides, which

I have regarded (and, I cannot but think, correctly so)

as aberrant, fossorial Cossonids. Moreover its immersed

head and obsolete eyes, as well as its bald and rather

shining surface (which is entirely free from mud-like

scales), are characters which are quite unprecedented in

any of the hitherto-known representatives of the Dryoph-

thorides.

In other respects (each of them of considerable im-

portance), otiomimetes recedes from the Dryophthorides

Genera of the Cossonide. 505

in its exceedingly minute size; in its surface, although

deeply sculptured, being very much less so than in that

subfamily ; in its slenderer rostrum, which has the antennze

implanted a trifle before (instead of behind) the middle ; —

in its elytra being more attenuated posteriorily, and with-

out any trace either of cost or of the cariniform structure

on either side of their apex ; in its antenne (which are

much less incrassated) having their scape suddenly thick-

ened into a very elongate apical knob, their funiculus-

joints (the second one of which is appreciably longer than

those which follow it) more loosely connected inter se, and

their club larger and more abrupt; in its femora being

armed beneath with a very small and indistinct tooth ;

and in its feet (which, as just stated, are pseudotetramerous)

being broader and more abbreviated,—the first and second

articulations (particularly the latter) being transverse, the

third one deeply bilobed (but with the lobes no¢ divari-

cating), and the ultimate one (the claws of which are very

largely developed) short and thick. :

2. PsILODRYOPHTHORUS (nov. gen.).—In its 4-jointed

funiculus, transverse eyes, obsolete scutellum, costate elytra,

and slender, pentamerous feet, the remarkable insect for

which the present genus is established, and which has

been communicated by Mr. Pascoe as having been taken

by Mr. Wallace at Saylee, in the north-west of New

Guinea, is essentially a Dryophthorid ; and yet it is an

exceedingly anomalous member of its subfamily, more

especially in the fact of its surface (instead of being opake

and thickly besmeared with dirty, mud-like scales) being

slightly shining, and almost bald,—the punctures only (or

a certain portion of them) being filled-up with the parti-

cular kind of brown deposit which is so characteristic of

the immediately-allied forms. And it is further conspi-

cuous for its prothorax (which is largely developed) being

almost as wide behind as the base of the elytra, and nearly

even,—there being scarcely any indication of inequalities,

or of an anterior constriction ; and for its elytra being

broadly and distinctly scooped-out in front (causing the

shoulders to appear prominent, or porrect), and without

any tendency to be cariniform at their apex. Its rostrum

is rather short, thick, and cylindrical (being of nearly

equal breadth throughout), and is not roughened as in the

generality of the Dryophthorides.

506 Mr. T. Vernon Wollaston on the

3. STENOMMATUS (nov. gen.).—The very interesting

little insect on which I have founded the present genus is

from Mexico, and has been communicated by Mr. Fry.

While possessing all the essential features of the Dryoph-

thorides (as instanced by its 4-jointed funiculus, elliptical

body, transverse eyes, obsolete scutellum, conspicuously

5-articulated feet, and minute claws), it recedes completely

from Dryophthorus proper (and, therefore, & fortior7, from

Tetratemnus) in several most important particulars,

especially however in its considerably longer, slenderer,

more parallel and arcuated rostrum ; in its very much nar-

rower and more transverse eyes (which are so narrowed,

and prolonged, beneath the head, as to be nearly con-

fluent) ; and in all its coxze, though particularly the four

posterior ones, being more widely separated. In other

respects it differs from Dryophthorus in its smaller size

and still more elliptic outline, which is a good deal at-

tenuated at its hinder apex; in its surface (instead of

being unequally besmeared with a kind of coarse, mud-

like, scaly deposit) being densely and evenly covered with

an extremely fine, velvety, somewhat silken, cinereous

pubescence; in its elytra not being cariniform at their

extremity, though with their second costa (or raised costi-

form interstice) more conspicuously elevated, or prominent,

behind ; in its antennz (particularly as regards the scape)

being longer, and with the club more developed; and in

its metasternum being a little shorter.

4, DryopuTHorus (Schéuherr, Cure. Disp. Meth.

332. 1826).—Although I have had no opportunity of

examining them, I believe that the majority of the species

which have been referred to Dryophthorus are generically

distinct from the European D. lymexylon, which is ex-

pressly stated to be the type of the group; and I suspect

therefore that the genus Tetratemnus, which I lately enun-

ciated in order to receive an insect which was taken abun-

dantly by Mr. G. Lewis-in Japan, will be found eventually

to embrace them. Be this however as it may, the genus

Dryophthorus, as represented by its acknowledged type,

is too well known to require comment; suffice it to observe

that the various published diagnoses of it (not even ex-

cepting that of Lacordaire) appear to me to be at fault in

their definition of some of its most important characters,—

the result apparently of their having been drawn out, not

from the type alone, but partially also from some of the

Genera of the Cossonide. 507

allied forms which I regard as Tetratemni. In Dryoph-

thorus proper, however, the anterior coxe are rather more

approximated than in Tetratemnus, the body is more

elliptic (or medially-widened), the prothorax is a trifle less

developed, the elytra are not so broadly cariniform at their

apex, and the rostrum, antenne, and legs are appreciably

longer. Nevertheless in their opake and very coarsely-

sculptured surface (which is more or less densely besmeared

with whitish-brown, mud-like scales), as well as in their

costate elytra and 4-jointed funiculus, and in the fact of the

fourth articulation of their slender, filiform feet being (in-

stead of minute and hidden) exposed and distinct, the two

genera are coincident. The D. lymexylon, which (as just

stated) may perhaps prove to be the only Dryophthorus

proper hitherto made known, appears to occur, more or

less sparingly, throughout northern and central Europe.

5. TETRATEMNUS (Wollaston, Trans. Ent. Soc. Lond. 9.

1873).—As already implied, the members of this genus,

which (if my conclusions be correct) are extra-Kuropean

and appear to be widely spread over the world, present

many characters which, as it seems to me, cannot but

distinguish them generically from the European Dryoph-

thorus lymexylon. Not to speak however of those species

which I have had no opportunity of examining, and which

may or may not prove to be Tetratemni, 1 may add that

at any rate the Japanese Cossonid (the TZ’. sculpturatus,

Woll.) for which the group was proposed, recedes from the

D. lymezxylon in its anterior coxe being rather more

widely separated, whilst the hinder pair, on the contrary,

are not quite so remote as in that insect; in its antenne,

rostrum, and legs being a little shorter; in its prothorax

being proportionately a trifle more developed ; in its elytra

being narrower and more parallel (or laterally-compressed )

and very much more broadly cariniform on either side of

their apex; and in its tarsi being especially more abbre-;

viated. Its rostrum also is less appreciably widened

immediately in front of the particular point at which the

antennz are inserted. Its dark and opake surface how-

ever is as coarsely sculptured, and besmeared with the

same kind of whitish-brown, mud-like scales (or, as it

were, scaly deposit), asin Dryophthorus proper. Although

it is probable that the group has a wide geographical

range, the J. sculpturatus is, (for the reason already

TRANS. ENT. SOC. 1873.—PART Iv. (OCT.) rome)

508 Mr. T. Vernon Wollaston on the

given, the only member of it for which I am at present in

a position to vouch; and that one appears to be common

in the Japanese archipelago, having been met with by

Mr. G. Lewis near Nagasaki in the island of Kushiu, and

at Hiogo in the island of Nipon.

6. SYNOMMATUS (nov. gen.).—If there had been any

question concerning the intimate relationship which exists

between the Dryophthorides and Pentarthrides (of which

I have never myself entertained the slightest doubt), it

would have been thoroughly dispelled by a genus like the

present one,—which, although pertaining to the latter, is

at first sight so unmistakeably a Dryophthorid that it is

difficult to conceive that it can belong to any other group.

Yet the most essential features of that well-marked sub-

family, namely a 4-jointed funiculus and ordinary penta-

merous feet, are entirely wanting to it,—the former in

Synommatus being jive-articulate, and the latter on the

usual Rhynchophorous pattern. Yet so marvellously do

its external facies, sculpture, and clothing, no less than its

narrow, transverse, sunken eyes, the general proportions

of its rostrum and antennz (barring the extra funiculus-

joint), and the structure of its abdomen and tibize accord

with Dryophthorus that one can scarcely resist the con-

viction that it isas much a member of the one subfamily

as of the other ; and my own opinion, consequently, is that

it is as nearly as possible osculant between the two.

Although agreeing very much better than Pentacoptus

and Cherorrhinus do with the Dryophthorides, yet in con-

junction with those genera (in the latter of which the elytra

are cariniform on either side of the apex) it may be said

to constitute a most complete passage between the sub-

families in question,—though of necessity claimed by the

Pentarthrides (with which, however, it has far less, prima

facie, in common) on account of the structure of its funi-

culus and feet.

In the formation of its eyes Synommatus stands alone

amongst all the Cossonideous types with which I am

acquainted, the nearest approach to it being the genus

Stenommatus from Mexico; for not only are they very

much more approximated on the upper-side than is the

case in any of the Dryophthorids which have hitherto

been brought to light, but (which is still more anomalous)

they are completely confluent beneath,—the two to-

gether, consequently, well-nigh encircling the entire head!

Genera of the Cossonide. 509

Amongst other peculiarities, our present insect is remark-

able for its elliptic outline, for its long and parallel but

arcuated rostrum, for its funiculus being gradually much

increased in width towards the club, and for the latter

being extremely large and solid,—though obliquely trun-

cate at the mner apex, at which particular point it is

densely clothed with a velvety pubescence. Its prothorax

(which is but slightly constricted in front) is nearly cylin- —

drical, and very much narrower than the elytra, the latter

(which have their interstices, especially the alternate ones,

costiform) are wide in front but acuminated behind, its

legs are exceedingly long and thickened, its tibie are

somewhat curved (the four hinder ones moreover being

armed at their apical angle with a short but robust spine),

its third tarsal joint is simple, and its front coxee are con-

tiguous, the intermediate ones but very slightly separated,

and the hinder pair exceedingly remote.

The S. confluens is from the collection of Mr. Pascoe,

and was taken by Mr. Wallace at Sarawak in Borneo.

7. CHERORRHINUS (Fairmaire, Ann. de la Soc. Ent.

de France, 742. 1857).—I am indebted to John Gray,

Esq., for an opportunity of inspecting the European genus

Cherorrhinus, of Fairmaire; and it is not without the

greatest astonishment that I have observed the excessive

inaccuracy of the original diagnosis in assigning it to the

Dryophthorides,—an imacecuracy which is quite unpardon-

able, and which has misled every subsequent author (in-

cluding even Lacordaire) who has been content to trust to

the published details, and not to examine them for him-

self. The primd facie aspect of its opake, deeply-sculp-

tured surface, which is besmeared with dirty, mud-like

scales, in conjunction with the carimiform structure on

either side of its elytral apex, are without doubt marvel-

lously suggestive of Dryophthorus,—so much so indeed

that it may fairly be regarded as establishing, im conjunc-

tion with Synommatus, a curious affinity between the

Dryophthorus-type and the subfamily Pentarthrides (to

which it belongs); but there the resemblance altogether

ceases; and it is surprising how any careful Coleopterist

could be misled by characters so eminently superficial.

In real fact its funiculus is five-articulate, which at once

removes it from the Dryophthorides—in which that organ

is composed of only four joints. Then its feet are on the

ordinary pseudotetramerous pattern, instead of as in the

002

510 Mr. T. Vernon Wollaston on the

Dryophthorides distinctly 5-jointed (the fourth one in that

subfamily not being minute and hidden, but appreciable

and unreceived). Yet so completely was Lacordaire led

into error by the original diagnosis, that he not only

accepted the insect (on account of the supposed structure

of its funiculus) as a Dryophthorid, but naturally enough

felt compelled so far to modify the characters of that well-

defined subfamily so as to admit within its bounds the

ordinary pseudotetramerous foot! It is, however, in re-

ality, a normal member of the Pentarthrides, and is very

intimately related to my genus Pentacoptus which was

detected by Mr. G. Lewis in Japan. It completely lacks,

moreover, the fusiform, or subelliptic, outline of the Dry-

ophthorides ; whilst its exceedingly incrassated legs and

tarsi are in strange contrast with those of that subfamily—

in which those parts are comparatively thin and wiry;

and its eyes (instead of being sunken, transverse, and de-

pressed) are rounded and very prominent—as in the Pen-

tarthrideous Pentacoptus. Its metasternum too is shorter

than that of the Dryophthorides; and its four anterior

coxze are perceptibly more approximated.

From the Japanese Pentacoptus (to which it is inti-

mately allied), Cherorrhinus differs mainly in its larger

size and less narrowed prothorax, in the cariniform struc-

ture on either side of its elytral apex, in its anterior coxze

being rather less widely separated, and in its first and

second abdominal segments being divided by a very deeply

sinuated line, instead of a perfectly straight one.

The Cherorrhini appear to occur in southern Europe,

the genus having been first met with in Sicily.

8. Penracorrus (Wollaston, Trans. Ent. Soc. Lond.

12. 1873).—In its very coarsely sculptured and opake,

though somewhat besmeared surface, its short, broad,

parallel rostrum, nearly obsolete scutellum, and costate

elytra, the present remarkable little genus has almost as

much in common, at first sight, as Cherorrhinus has,

with the Dryophthorides; nevertheless its 5-jointed funi-

culus, and its small, rounded, and prominent eyes, in con-

junction with its elytra showing no traces of the peculiar

cariniform structure at their apex which is so marked a

feature in that group, its comparatively incrassated legs,

and its ordinary pseudotetramerous feet (the third joint of

which is a good deal widened and bilobed), will of them-

selves at once remove it from the members of that sub-

ta Bn

Genera of the Cossonide. 511

family. I have already pointed out in what it principally

differs from Cherorrhinus. It was detected by Mr. G.

Lewis in the Japanese archipelago,—namely at Nagasaki,

in the island of Kushiu. ,

9. LypPrRopEs (nov. gen.).—The single example from

which I have compiled the diagnosis of the present genus,

which was captured by Mr. Wallace in Sula, one of the

islands of the Malay archipelago, has been communicated

by Mr. Pascoe; and it is especially important as supply-

ing another well-defined type in the subfamily Pentar-

thrides—in which the funiculus is only 5-articulate. More-

over its opake and deeply sculptured surface, .which is

densely besmeared with mud-like scales (or, as it were, a

kind of dirty-whitish, scaly deposit), added to its almost

obsolete scutellum, and its thick, abbreviated feet (the first

joint of which is short, and the third one wide and very

deeply bilobed), place it in the immediate vicinity of

Pentacoptus and Cherorrhinus. It is abundantly dis-

tinct, however, from both of those groups, not merely in

its much narrower and cylindric body (which is of nearly

equal breadth throughout), but likewise in its much longer

and slenderer rostrum, its less incrassated and less abbre-

viated antennz (which have their second funiculus-joint

appreciably longer than those which follow it), and in its

more elongated metasternum (which indeed is scarcely

shorter than that of Pentarthrum and Stenotrupis). Its

eyes, although prominent, are less remarkably so than in

Pentacoptus; and its elytral interstices are not so costate.

In primdé facie aspect the insect calls to mind what we

might almost suppose to be an exceedingly diminutive

state of the European Lyprus cylindricus,—a circumstance

which, however fanciful, has suggested both its generic

and specific names.

10. PHL@OPHAGOMORPHUS (nov. gen.).—In its rather

lengthened cylindric-ovate outline, which is narrowed in

front and gradually expanded behind (the prothorax being

considerably reduced in size, and much narrower than the

elytra), as well as in the fact of its four anterior coxze

being (especially as regards the front pair) greatly approxi-

mated, the present genus has much the prima facie aspect

of Phleophagus ; nevertheless its funiculus is only 5-articu-

late, its scutellum is conspicuous, and its rostrum and

(much thicker and more abbreviated) antennz are very

512 Mr. TF. Vernon Wollaston on the

differently constructed. In reality it belongs to that par-

ticular section of the Pentarthrides in which the scutellum

is developed and the surface bald, and it is remarkable

amongst the immediately-allied forms for its somewhat

convex, Phlwophagus-like body, for its (rather short and

broad) rostrum being a good deal contracted, or as it were

pinched-in, at the base, for its eyes being (instead of pro-

minent) depressed, and for its four anterior legs being (as

in the Phleophagi) much more approximated at their base.

Its surface (which is shining) is of a reddish, and slightly

pellucid, chestnut hue,—with the head, rostrum, and femora

a little darker than the rest; its antennz are somewhat

thickened, with their second funiculus-joint not at all

elongate; and its feet have their first articulation (as in

Phleophagus) appreciably lengthened, and their third one

minutely (and not very distinctly) bilobed. ‘The example

from which the generic details have been compiled is

South-American (having been received from New Gra-.

nada), and has been communicated by Mr. Fry.

11. PsEUDOPENTARTHRUM (nov. gen.).—The rather

obscure little Cossonid which forms the type of the present

genus, is from Mexico, and has been communicated by

Mr. Fry; and its primd facie aspect is so much that of a

minute and cylindrical Phlwophagus, that until I observed

that its funiculus is only 5-jointed I had regarded it as a

member of that group. In reality however it is very close,

in affinity, to Pentarthrum,—from which it nevertheless

recedes in its very much smaller size and shortly-cylindri-

cal body, in its more abbreviated and relatively broader

(though equally parallel) rostrum, in its prothorax and

metasternum being very much less elongated, and in its

anterior cox being much more approximate. Indeed

the latter are almost exactly the same as in Phlaophagus,

the front pair being nearly contiguous; and its prothorax

also, which is oval (instead of elongate and subtriangular),

is almost on the Phlaophagus-pattern. Its under-seg-

ments are slightly scooped-out, or concave, after the

fashion which obtains in so many of the Pentarthrides ;

its surface is completely bald, black, and but very slightly

shining ; and the third articulation of its feet is simple.

In point of fact, however, the present genus is some-

what intermediate between Pentarthrum and Phleopha-

gomorphus, agreeing with the latter in its more approxi-

mated anterior. cox ; nevertheless it entirely wants the

Genera of the Cossonide. 513

very peculiar rostrum of the latter, which is curiously

pinched-in (or suddenly constricted) at its base ; and it is

likewise smaller and more cylindrical (the prothorax being

proportionately wider, and the elytra more parallel), of a

darker hue and duller surface, with its metasternum and

. limbs more abbreviated, and with the first joint of its feet

less elongate, and the third one more decidedly simple.

12. XENOSOMATIUM (nov. gen.).—The very minute

Pentarthrid for which I have established the present

‘ genus has been communicated by Mr. Pascoe, and was

captured by Mr. Wallace in the Malayan archipelago.

Apart from its diminutive size and 5-articulated funiculus,

its greatly abbreviated second funiculus-joint, and its

abrupt, largely developed club, it is at once remarkable

for the structure of its tibie,—which are rather short,

broad, and triangular, and have their terminal hook in the

four posterior ones abbreviated, straight, and spiniform,

but still shorter (in fact obsolete) in the front pair (where

it is replaced by a robust and owtwardly-curved pubescent

spine which arises from the inner angle). This tibial

modification is very peculiar, and one which I do not re-

member to have observed in any other Cossonideous group.

In minor details Xenosomatium is conspicuous for its

(somewhat short, broad, and arcuated) rostrum being a

good deal constricted at the base, behind the insertion of

the antennz (which arise nearer to the base than is usual

in the Pentarthrideous types); for its scape being long

and backwardly-curved, as well as greatly clavate (though,

at the same time, obliquely lopped-off at the inner apex) ;

for its eyes being extremely large and prominent; and for

its feet having their first three joints thickened and sub-

equal, but the ultimate one rather slender. In its piceo-

ferruginous hue Xenosomatium agrees with the majority

of these immediate forms, but its sculpture is finer and

lighter than is usually the case.

13. Penrarturum (Wollaston, Ann. Nat. Hist. xiv.

129. 1854).—Judging from the twelve exponents which

have hitherto been brought to light, the Pentarthra are

more or less narrow and parallel insects, closely sculptured,

nearly always free from scales and pubescence, either

piceous or castaneous in hue, and but very slightly shining.

Their eyes are prominent, and, together with the scutellum,

conspicuous; their prothorax is rather large, and, like the

514 Mr. T. Verna Wollaston on the

metasternum, elongate; their rostrum (which varies in

length according to the species, but which is never very

long) is robust and linear, though sometimes obsoletely

constricted towards the base; and their third tarsal joint

is either slightly bilobed, or else narrow and simple. In

the European P. Huttoni, which must be regarded as the

type of the genus, as well as in the P. Zealandicum, and

in the two species from Chili, the second articulation of

the 5-jointed funiculus is appreciably a little longer than

those which follow it; but this is less evidently the case in

the other members of the group which have hitherto been

observed. The Pentarthra are somewhat peculiar in their

habits,—attaching themselves to old planks, boards, rafters,

casks, &c., on the dry, and often tinder-like, wood of which

they appear to subsist (and that too, occasionally, when the

latter are even partly buried in the soil); a mode of life

which is equally indicated in (the nearly blind) Amauror-

rhinus, and in Hexarthrum of the true Cossonides. On this

account we may expect that their acquired areas of distribu-

tion will be found eventually to be wide ; and, in accordance

with this conjecture, it is a significant fact that the expo-

nents which have hitherto been discovered should occur in

countries so remote from each other as western Europe,*

* Until quite recently I had looked upon the P. Huttoni as peculiar to

England, and indeed it has not as yet been recorded for any other country;

but, having, a few weeks ago, received some Cossonide from Dr. Sharp, I

was surprised to find that two typical examples (which were included

amongst them), of the “Rhyncolus Hervei” of Allard (A beille, v. 475.

1869), and which appear to have been captured at Rennes, are identical

with my Pentarthrum Huttoni, described (fifteen years before) from

examples taken near Exeter. In the Munich Catalogue the department of

Finisterre is given as the locality for the “Rhyncolus Hervei ;” so that at

any rate the extreme western portion of Brittany is the only region, beyond

England, in which it has hitherto been observed ; and it is a significant

fact, from a geographical point of view, that that particular district is

exactly opposite to Devonshire—on the southern side of the Channel. Its

precise places of capture in this country are, up to the present date, three,—

namely, the vicinity of Exeter (where it was met with originally, at

Alphington, by my nephew, the Rev. H. W. Hutton) ; Teignmouth (where

on two or three different occasions I have myself found it), and Plymouth

(where it was detected by Mr. Reading). Apart from its many other

characters, the fact of its funiculus being composed of only five joints

ought certainly to have prevented it from being re-described as a Rhyn-

colus—in which that organ has invariably seven articulations ; but the

slovenly manner in which continental entomologists are apt to mount their

specimens, every limb and joint being hopelessly concealed beneath, will

perhaps explain a blunder which is nevertheless utterly unpardonable. It

is scarcely less fragrant’ however than the similar miscalculation of the

funiculus-joints in Cherorrhinus, which has resulted in that genus having

been assigned hitherto to a subfamily with which it has next to nothing in

the island of Ascension,* the Malayan and Japanese archi-

pelagos, New Zealand, Chili, and Brazil.f

14. SERICOTROGUS (nov. gen.).—I am indebted to Dr.

Sharp for the very curious little Pentarthrid for which the

present genus is established; and he appears to have ob-

tained it from Mr. Lawson, of Scarborough, by whom it

was received from Auckland in New Zealand. Its dis-

tinct scutellum and largely-developed eyes place it very

near to Pentarthrum proper; nevertheless in its smaller

bulk, and slenderer aud more fusiform outline (the elytra,

as in Amaurorrhinus, being narrowed anteriorly), and in

its somewhat brassy surface, which is sparingly clothed

with a coarse, silken, decumbent seneo-cinereous pubescence,

as well as in its less elongated metasternum (which is like-

wise more on the Amaurorrhinus type), and the widely

bilobed third joint of its feet, it altogether recedes from the

members of that group. Its rostrum, too, is a trifle longer,

thinner, and more curved than in the majority of the Pen-

tarthra, and has the antennz implanted into it rather more

conspicuously before the middle ; the latter are a little less

thickened ; its head is more exserted ; its prothorax (which

is slightly concave beneath) is convexer, more regularly

rounded at the sides (it being neither subtriangular nor

subcylindrical), and is nearly free from an anterior con-

striction: and its elytra have apparently no tendency to

be separately rounded-off, and subrecurved, at their ex~

treme apex.

15. STENOTRUPIS (nov. gen. ).—The exceedingly narrow,

common ; or than placing Hexarthrum amongst the Rhyncoli, because

the articulations of the same organ were incorrectly counted! But if col-

lectors will not take the trouble to expand their specimens so that the parts

may be distinctly seen, how can we wonder at the inevitable results ? Still,

one would at least have supposed that before enwnciating a new form, the

microscope would, as a matter of necessity, have been appealed to.

* The presence of my P. cylindricum in the island of Ascension appears

to have been (as indeed I always anticipated) merely accidental ; for an

example is now before me which was captured by Mr. Fry in Brazil, and

another which was taken by Mr. Wallace in Gilolo of the Malayan archi-

pelago. In all probability therefore it is a species which, like certain

others, is liable to follow in the wake of civilization.

+ The little insect from St. Helena which I described two years ago as

an aberrant Pentarthrum, under the name of P. subc@cum, proves on a

closer examination to be no Pentarthrum at all, but-more intimately re-

lated to Amaurorrhinus (or Mesoxenus). It is, however, distinct from

even the latter, and forms the type of my genus Pseudomesoxenus,—

enunciated below.

516 Mr. T. Vernon Wollaston on the

and sometimes minute, insects for which the present genus

is proposed appear to have been confounded hitherto with

Catolethrus—into which they seem to have been admitted

as abnormally small members ; and, in accordance with

this, a very pallid and diminutive one, from Cuba, has

been communicated by Mr. Pascoe with a very old label

appended to it, bearing the name “Catolethrus palmeus,

Schén.” There is no species, however, of supposed Cato-

lethrus, so far as I can ascertain, which bears that specific

title, either in the ‘ Genera Curculionidum’ or the Munich

catalogue; and I am compelled, therefore, to conclude

that it is an unpublished one; yet the fact itself tends

nevertheless to prove that the exponents of the present

genus have, as just mentioned, been associated inadver-

tently with the Catolethri. But in reality, when closely

inspected, they will be seen to belong to even a different

subfamily from the latter,—their 5-jointed funiculus as-

signing them at once to the Pentarthrides. In addition,

however, to this primary distinction, Stenotrupis recedes

from Catolethrus in the insects which compose it being

smaller and narrower; in their head being much longer,

thicker, more oval and very much more exserted (or ex-

posed); in their rostrum being slenderer still, a little

widened towards the tip, and not appreciably divided from

the forehead; in their prothorax being more triangular,

and less constricted behind its apex; in their scutellum

being less conspicuous; in their elytra being minutely

pubescent at the apex; in their four hinder legs being

shorter ; in all their coxe being equally separated, or

apart; and in the third joint of their feet being unex-

panded and simple.

In point of fact, however, Stenotrupis is much nearer

to Pentarthrum,—particularly to such members of it as

_the P. angustissimum, from Japan; yet its species are

still narrower and more depressed; their head is longer,

thicker, oval and exserted; their rostrum (particularly in

the female sex) is more elongated and slender, and appre-

ciably widened in front; their eyes (instead of being

rounded and prominent) .are completely sunken, ovate

and more approximated above; their prothorax is more

triangular and less constricted behind its apex; their

elytra are minutely pubescent at the tip; their legs, par-

ticularly the four posterior ones, are much shorter; and

their coxe are, all of them, equally separated.

In all probability Stenotrupis will be found to have a

wide geographical range, though it is perhaps more

strictly tropical than Pentarthrum. At any rate one of

the species now before me is from Cuba, and another was

captured by Mr. Wallace in Makian—one of the islands

of the Malay archipelago.

16. Mrcorocossonus (nov. gen.).—The minute Cossonid

(which was taken by Mr. Wallace at Saylee on the north-

west coast of New Guinea, and which has been communi-

cated by Mr. Pascoe) from which the characters for the

present genus have been drawn out, is manifestly a good

deal allied to Stenotrupis,—with which it agrees in its

thickened, elongate, greatly exserted head, its narrow and

parallel outline, its depressed surface, and in the fact of its

legs being equally distant at their base. Nevertheless, if

the example before me may be taken as a type of its

group, the body is even still smaller than in Stenotrupis

(the entire length being scarcely one line), but relatively

not quite so slender; its rostrum (which, as in most of the

members of that genus, is appreciably dilated towards the

apex) is much shorter and wider; its eyes are considerably

more developed, and not so flattened; its elytra are free

from minute pubescence at their apex; its antennz are

inserted very much nearer to the base of the rostrum; and

its coxee (although, as in that group, equally separated)

are distinctly more remote. Its general contour and

outline are somewhat that of an exceedingly diminutive,

flattened, and pallid Mesites; but its 5-joimted funiculus

and the peculiar construction of its rostrum, as well as its

numerous other features, entirely remove it from the sub-

family Cossonides.

17. CossonIDEUS (nov. gen.).—In its comparatively

large and Cossonus-like body (which is much depressed,

deeply sculptured, parallel-fusiform in outline, and of a

rather pale, though somewhat variegated, hue) the curious

insect for which this genus is proposed, and which is com-

municated by Mr. Pascoe as having been received from

Champion Bay in western Australia, seems altogether

anomalous amongst the Pentarthrides ; nevertheless its 5-

jointed funiculus, and the structure of its robust, parallel

rostrum are quite in accordance with the members of that

subfamily. Apart, however, from the characters just

enumerated, it may be known by its excessively large and

518 Mr. T. Vernon Wollaston on the

prominent eyes; by its antenne, which have their second

funiculus-jomt conspicuously longer than those which

follow it, being inserted about the middle of the rostrum ;

and by its exceedingly elongate and greatly developed

legs,—the femora of which are much incrassated, or

clavate, and are rather roughened with a few minute

and indistinct asperities, or tubercles, on their inner sur-

face; whilst the tibiz are sinuated internally, and pro-

duced into a small but evident spinule at their inner angle,

and the tarsi (especially their terminal articulation) are

elongate.

Cossonideus may very possibly be the representative of

an important Pentarthrideous form in Australia; but in

external facies it nevertheless recedes greatly from the

Pentarthrides as hitherto known; though at the same

time it must be admitted that the (comparatively diminu-

tive) Microcossonus Wallacei, from New Guinea, makes

likewise a decided approach (though certainly a less strik-

ing one) towards the Cossonus and Mesites type.

18. Tycutopes (Wollaston, Trans. Ent. Soc. Lond.

16. 1873).—This is altogether one of the most curious of

the Cossonideous forms with which I am acquainted,—its

rather wide, subdepressed, oblong-elliptic body (which, as

in most of the allied groups, is slightly shining, castaneo-

piceous, and free from pubescence), in conjunction with

its extremely slender and cylindrical rostrum (I believe in

both sexes), its short, transverse prothorax, and thickened

legs, giving it more the appearance at first sight of some

member of the Erirhinides, in the vicinity of Tychius,

than of a Cossonid. Its antennz (which are rather

slender, and implanted considerably behind the middle of

the rostrum) have their scape short and a good deal

flexuose (and, as it were, obscurely scooped-out on the

underside), and likewise the second articulation of their

lax, 5-jointed funiculus considerably longer than those

which follow it. Its scutellum is very conspicuous, and

its feet’ (which are rather thick, and largely developed)

have their third articulation deeply bilobed. Its meta-

sternum is a little less elongated than is the case in Pen-

tarthrum, Stenotrupis, Lyprodes, Leptomimus, and others.

It was detected by Dr. A. Adams in the Japanese archi-

pelago,—namely on the island of Awasima, off the north-

west coast of Nipon.

Genera of the Cossonide. : 519

19. TycHIosoMA (nov. gen.).—The insect for which I

have founded the present genus is from the Philippine

Islands, and has been communicated by Mr. Pascoe. It

is very closely allied to the Japanese Tychiodes Adamsit,

—from which, however, it differs in being not only larger

and more depressed and with the limbs longer, but like-

wise in having its antennz more medially inserted, with

the scape especially more lengthened, less arcuate, and

without any tendency to be hollowed-out internally, and

with the funiculus gradually much more widened, and

consequently with the club (which is itself longer) less

abrupt. In addition to which, its prothorax (which is

equally small) is more triangular, or less transverse, as

well as (together with the under-segments) extremely

shining and almost unsculptured; its prosternum is

clothed, between the anterior cox, with fulvescent pile ;

and its front tibia (instead of being simple) are slightly

scooped-out towards their inner apex, the emargination

being barbed posteriorly with strong fulvescent hairs.

20. Lerromimus (nov. gen.).—The two species now

before me for which the present genus is established, and

which have been communicated by Mr. Pascoe as having

been obtained by Mr. Wallace in the island of Gilolo, of

the Malayan archipelago, combine many very curious

features which are essentially their own. In their bodies

being exceedingly narrow and parallel they agree with

Stenotrupis ; but they nevertheless entirely want the

elongate, thickened, exserted head, and the completely

depressed eyes, of that genus; their rostrum too is very

much more lengthened and slender (not being subdilated

anteriorly); their prothorax and antenne, as well as their

second funiculus-joint, are much more elongated; the

third articulation of their feet is more expanded and

bilobed ; and their legs (instead of being equidistant from

each other at the base) have the intermediate coxe rather

’ widely separated, but the front and hinder pairs appreciably

(and equally) more approximate. This last-mentioned

peculiarity is rather anomalous amongst the Cossonide,

and particularly so amongst the Pentarthrides. In other

respects Leptomimus is remarkable for the opake, reddish-

brown, and most closely sculptured surface of its two

hitherto-discovered exponents,—one of which, moreover,

is clothed with a short, setiform pubescence, whilst the

other appears to be bald. In all probability the group

520 Mr. T. Vernon Wollaston on the

will be found to play an important part in the Rhyncho-

phorous fauna of the Malay archipelago, the Z. delicatulus

having (as I am informed by Mr. Pascoe) been stated by

Mr. Wallace to be common amongst the bamboos.

21. LAMPROCHRUS (nov. gen.).—The superb Cossonid*

for which the present genus is proposed, and which was

discovered by Mr. Melliss at St. Helena, I admitted two

years ago (albeit not without some hesitation) to Microxry-

lobius,—having been content at the time to cite it as a

large and aberrant member of that locally-important group ;

yet a closer inspection of its real structural details would

certainly imply that it must be treated in reality as alto-

ecther distinct,—its extremely elongate and slender rostrum

(which in the male sex is rather more robust and sculptured,

and slightly dilated before the middle, at the insertion of the

antennz, much after the fashion which obtains in Mesztes

of the true Cossonides), in conjunction with its equally

elongated antenne, legs, and feet (the first of which have

their second funiculus-joimt, and the last their basal one,

greatly lengthened), being of themselves more than suf-

ficient to establish its claims for separation. In its fusi-

form outline and shining, brassy surface it might well be

mistaken at first sight for a gigantic exponent of that

section of Acanthomerus in which the femora are un-

armed; but the characters above enumerated (in addition

to its slightly pubescent body, as in certain of the Microzry-

lobii proper) will at once distinguish it from the members

of that genus. The fact, however, of its funiculus being

5-articulate, its scutellum obsolete, and its third tarsal

joint deeply bilobed, added to its fusiform outline and: its

metallic lustre, is too significant not to indicate its mani-

fest relationship with the other Pentarthrideous genera

(Microxylobius proper and Acanthomerus) which are so

remarkably developed, as regards their specific modifica-

tions, in the little island of St. Helena.

22. ACANTHOMERUS (Boheman, Res. Eugen. 141.

1858).— The <Acanthomeri, which are peculiar to the

island of St. Helena, may be said to be those members

of Microrylobius (as hitherto understood) in which the

body is highly polished, less sculptured, and brassy, and

totally free from any traces of even the minutest pubescence,

€ WM. cossonoides, Woll., Ann. Nat. Hist. 403 (1871).

Genera of the Cossonide. - 521

and in which the second joint of the funiculus is conspicu-

ously longer than any of those which follow it. Their

rostra, too, are usually a trifle longer, and relatively a

little less thickened, than in Microxylobius proper, with

the antenne implanted just perceptibly nearer to the apex;

and in the typical members of the group (the A. armatus,

conicollis, and monilicornis) the two hinder femora are

furnished with an acute spine at the base of their upper

edge. In the four remaining species which have as yet

been detected (namely the terebrans, obliteratus, debilis,

and angustus) the femora are unarmed. The A. moni-

licornis, however, presents a slight exception as regards

its funiculus-joints, the last four of which are almost of

equal length and breadth,—the first of them being scarcely

at all elongated; but in every other respect it is typical.

23. Microxyiosgius(Chevrolat, Trans. Ent. Soc. Lond.

i. 98. 1836).—A more careful examination of the many

remarkable and dissimilar Cossonids, from St. Helena,

which I have hitherto recorded (chiefly on account of their

funiculus being 5-articulate) as Microzylobii, has con-

vinced me that it will be better (indeed perhaps necessary)

to treat’ them as exponents of two distinct genera,—or, if

we include the comparatively gigantic “ M. cossonoides”

(which was enunciated by myself, as such, two years ago),

of three. As thus restricted, the dark and almost un-

metallic members of the group will be the Microxylobii

proper,—in which moreover the surface, instead of being

highly polished and perfectly bald, is subopake, more or

less roughened, and with a tendency to be sparingly

studded with a very minute pubescence (which, however,

is sometimes barely traceable even beneath a high magni-

fying power). In fact, although distinct in the MW. vestitus,

and just appreciable in the dacertosus and dimidiatus, this

pubescence may be said in the Westwoodii and lucifuqus

to be almost, if not indeed entirely, absent. These five

species moreover, with the exception of the last, are the

smallest of the assemblage, and have their rostra relatively

a trifle broader and thicker (it being in some instances

almost subtriangular), and the second articulation of their

funiculus hardly at all longer than those which follow it.

In the excessive brevity of their metasterna, Microxylobius,

Acanthomerus, Lamprochrus, and Amaurorrhinus are

nearly coincident ; though perhaps it is in Microxylobius

that it is more particularly shortened.

522 Mr. T. Vernon Wollaston on the

24, Microrrisus (nov. gen.).—The very remarkable

little Cossonid for which the present genus has been

established is from the collection of Mr. Pascoe, and was

captured by my nephew, Captain F. W. Hutton, in the

Waikato district of North Island in New Zealand; and

it is peculiarly interesting as adding another well-defined

type to the escutellate section of the Pentarthrides in which

the eyes are nevertheless fully developed. In its fusiform

outline, dark-piceous hue, slightly shining surface, and

rather shortened, subconcave metasternum, it is in entire

accordance with most of the immediately-allied genera ;

but it is conspicuous for its rostrum being rather narrow,

elongated, and parallel, for its eyes (although small) being

prominent and less wide apart from each other than is

usual, for its prothorax being oval, regularly rounded at

the sides, and largely developed, and for the second joint

of its exceedingly lax funiculus being very appreciably

lengthened, and the third one of its feet much expanded

and deeply bilobed. But one of its most significant

features consists in the fact that, whilst the rest of its

body is completely bald, the base of its elytra and the

extreme hinder margin of its prothorax are studded, in

unrubbed specimens, with a few very fine, elongated hairs,

—thus feebly shadowing-forth what is so strongly ex-

pressed in the nearly-blind Pentatemni (of the Atlantic

archipelagos), and still more so in Halorhynchus (from

western Australia), the anomalous Onycholips (of the

Canarian group), and the Madeiran genus Lipommata,—

the last three of which are totally devoid of sight.

Whether however it at all indicates (as I am rather

inclined to suspect) a sand-infesting mode of life, as it

clearly does in the groups to which allusion has just

been made, I have no positive information. The exact

position of Microtribus, amongst the various forms which

up to the present time have been made known, appears to

be between Microxylobius, from St. Helena, and Mesoxe-

nomorphus from southern Africa.

It has given me great pleasure to name the type of this

interesting genus after Captain Hutton, to whose inde-

fatigable researches we are gradually becoming indebted

for a more complete knowledge of the New Zealand fauna

than has hitherto been brought to light.

25. MrsoXENOMORPHUS (nov. gen.).—The three ex-

amples for the reception of which I have been compelled

Genera of the Cossonide. 523

to establish the present genus have been communicated by

Mr. Janson, and are from British Caffraria in southern

Africa. In their fusiform outline, piceous hue, shining,

unpubescent surface, and obsolete scutellum, they are at

first sight very similar to Mesoxenus (now merged into

Amaurorrhinus) ; nevertheless the fact of their eyes

(although minute) being present, instead of obsolete,

throws them into a different, though proximate, section

of the Pentarthrides. And, when closely inspected, they

will be seen, further, to recede from Amaurorrhinus, not

only in their relatively narrower body and more elongated

prothorax and elytra, but likewise in their shorter, broader

and more parallel rostrum, into which their very much

more abbreviated antennz are implanted further from the

apex, in their lees (the front and hind pairs of which are

a trifle more approximate at their respective bases) being

also shorter, in their metasternum being appreciably more

elongated, and (together with their first abdominal seg-

ment) less scooped-out, or concave, and in the third joint

of their feet being more decidedly simple.

26. HeTEropsis (nov. gen.).—I am indebted to Dr.

Sharp for the remarkable little Cossonid for which the

present genus is proposed, and which was captured at

Auckland in New Zealand by Mr. Lawson,—after whom

I have had much pleasure in naming the species. Its 5-

jointed funiculus and obsolete eyes (which are minute,

sunken, and very rudimentary) place it near to Amauror-

rhinus ; nevertheless it differs from the latter, and the

cognate forms, in having a developed scutellum ; whilst

in its extremely short and broad rostrum (particularly of

the male sex), which is a little contracted posteriorly and

is divided from the head by a distinct frontal line, and its

abbreviated, abruptly-clavate scape, it possesses features

which are essentially its own. In other respects, Hete-

ropsis is conspicuous for its small size, and its narrow,

cylindrical, but somewhat depressed body, for its shining,

piceo-castaneous surface (which is very lightly sculptured

anteriorly), and for its rather short legs and elongated

metasternum.

27. AMAURORRHINUS (Fairmaire, Ann. de la Soc. Ent.

de France, 629. 1860).—Although the exceedingly short

and imperfect diagnosis which M. Fairmaire has given of

TRANS. ENT. SOC. 1873.—PART IV. (OCT.) PP

524 Mr. T. Vernon Wollaston on the

this genus does not call attention to a single structural

peculiarity beyond the fact that its funiculus is composed

of but five joints, I have nevertheless no hesitation in

identifying it with my Mesoxenus (from the Madeiran and

Canarian archipelagos), seeing that his specific description

of the type, namely the A. Bonnairii (= A. narbonnensis,

Bris.), from Corsica and the south of France, seems to

accord so well with an insect now before me, from Corfu,

which is unquestionably a Mesoxenus, as to leave little

doubt in my mind that it is even the actual species referred

to by Fairmaire. ‘This particular example has been com-

municated by Mr. Janson; and it is so closely allied to

the Mesoxenus Bewickianus, from Madeira, that I had at

first sight imagined it must be identical with it. A more

critical inspection however has convinced me that the two

~ are specifically distinct, though it is impossible to have the

slightest hesitation in assigning them to at all events the

same group; and I do not think, therefore, this being the

case, that Mesoxenus should be kept apart from Amau-

rorrhinus. Nevertheless I ought perhaps to mention that

Fairmaire makes no allusion whatever to the obsoleteness

of its eyes, which is the most important feature in the

insects now before me; and that he likewise speaks of the

antenne as “ in medio rostri insertz,” whereas those organs

are implanted considerably before the middle in the only

three representatives of my genus Mesoxenus which I have

hitherto examined. Still, the manifest looseness, and

brevity, of his diagnosis is sufficient to account for these

omissions; and it is my belief, as just stated, that the

genera in question are identical.*

Regarding therefore the Amaurorrhint and Mesozxeni

as coincident, I may add that the members of this genus

have the bald, rufo-castaneous, and slightly shining surface

of Pentarthrum ; nevertheless their obsolete eyes and

scutellum, and abbreviated metasternum, throw them into

a totally different section of the present subfamily. They

* In size, colour, outline and sculpture, the species from Corfu (which I

believe to be the A. Bonnairii of Fairmaire) almost exactly resembles the

Madeiran A. Lewickianus,—from which it merely differs in its prothorax

being a little less widened (or rounded-outwards) behind the middle, in its

rostrum being just appreciably slenderer and less expanded in front of the

antennze (which are themselves not gwite so thick), in its second funiculus-

joint being perhaps a trifle more elongate (though not so much so as in the

A. Monizianus), in its club being somewhat less developed, and in its

metasternum and first abdominal segment being more convex (or hardly

at all scooped-out, or concave).

Genera of the Cossonide. 525

are also more fusiform, or less parallel, insects than the

Pentarthra ; their prothorax is more rounded and convex ;

their elytra are less straightened, and more lightly sculp-

tured; their rostrum is a little longer and less robust ;

and their antennz (which are implanted a trifle nearer to

the apex of the latter) have their scape slenderer and

more curved. There is also a peculiarity about their

undersides (which is likewise the case in most of the

Microxylobiit and Acanthomeri, as well as m Lampro-

chrus, and in many of the true Cossonides),—the first

abdominal segment and the (very short) metasternum being

deeply impressed (at any rate in the two Atlantic-island

species) down the central region, causing them to be

hollowed-out, or concave. ‘Two out of the three Amau-

rorrhint with which I am acquainted (namely the <A.

Monizianus and Bewickianus) are found in the Madeiran

archipelago, and one of them likewise at the Canaries,

whilst the other occurs in the south of Europe; but the

sight singularity in their modes of life, which appear to

be much the same as those of Pentarthrum (as well as of

Hexarthrum, of the true Cossonides), renders it probable

that they will be found eventually to possess a more ex-

tended range.

28. PSEUDOMESOXENUS (nov. gen.).—The little insect

(hitherto unique) for the reception of which the present

genus is established was taken in the island of St. Helena

by Mr. Melliss; and it was recorded by myself, three

years ago, as a blind, aberrant Pentarthrum, under the

name of P. subcecum.* It is evident however that it has

a far closer affinity with Amaurorrhinus,—with which

indeed its obsolete eyes and scutellum, and its convex,

largely-developed prothorax, would tend to affiliate it.

Still, an accurate examination of its structural details has

convinced me that it cannot be treated as even an Amau-

rorrhinus ; for not only is its metasternum very appreci-

ably more elongated, and its rostrum thicker and sud-

triangular, but its elytra likewise are narrower and more

parallel and cylindrical, and its limbs are shorter and less

thickened,—the feet especially being slenderer and filiform,

with their third joint almost unexpanded and simple.

The underside moreover is convex, and has no trace of

the concavity which gives so remarkable an appearance to

the first abdominal segment and greatly abbreviated meta-

sternum of Amaurorrhinus and the allied groups.

29. PENTATEMNUS (Wollaston, Trans. Ent. Soc. Lond. -

2nd ser. v. 385. 1861).—In its obsolete scutellum and eyes

(the latter of which are very minute and indistinct, bemg

composed of only about six small lenses),“and its dark

piceous hue, and the fact of its funiculus being 5-articulate,

Pentatemnus agrees with Amourorrhinus ; but it differs

from it essentially in most of its other details, as well as in its

subfossorial mode of life. Thus, not only is its body (in-

stead of being bald) sparingly studded with elongate silken

hairs, but its elytra and under-surface are curiously and

thickly asperated with obliquely-impinged punctures, its

rostrum and antennz (the former of which is more strictly

parallel, and the latter are more medially inserted) are

much shorter and thicker, its legs are considerably more

incrassated, and its third tarsal joint is simple. Its tibial

hooks too are very much more developed,—the four hinder

ones being exceedingly powerful, and rather expanded, and

compressed, at their base, causing the tibiz. to seem as

though slightly rounded-outwards at their external angle.

The Pentatemni are sand-infesting, and somewhat fossorial,

in their habits (as indeed their pilose bodies, obsolete eyes,

and strongly-developed legs and tibial hooks would par-

tially imply), residing around the roots of shrubby plants

which stud the arid tracts of loose, drifting sand in certain

islands of the’ Canarian and Cape-Verde archipelagos,—

where they often descend to a considerable depth beneath

the surface. In such situations I have met with them in

Lanzarote, Fuerteventura and Grand Canary of the for-

mer, and in Sao Vicente of the latter.

30. HALORHYNCHUS (nov. gen.).—The insect for which

the present genus has been proposed is from the collection

of Mr. Pascoe, by whom it was received from Freemantle

in Western Australia; and it is perhaps the most impor-

tant of all the forms which he has communicated to me,—

as establishing most completely the manifest relationship

which exists (of which, despite the opinion of Lacordaire,

I have never myself entertained the slightest doubt) be-

tween the Pentarthrides and that singular department of

aberrant, fossorial Cossonids, to receive which I have

established the subfamily Onycholipides. Indeed so much

has it in common with Onycholips (with which it also

Genera of the Cossonide. 527

agrees in its total freedom from even the rudiments of

eyes) that I had at first sight supposed it to be a member

of that actual genus; nevertheless its 5-jointed funiculus,

parallel outline and obsolete scutellum, in conjunction with

its less completely approximated four anterior legs and

the structure of its abdominal segments and tibie, show it

to belong unmistakeably to that particular section of the

Pentarthrides which contains Pentatemnus. In point of

fact it is very intimately allied to the latter genus,—from

which it nevertheless recedes in its eyes being altogether

absent, in its tibize being armed at their inner angle (as in

Lipommata) with a distinct spinule, and in the two hinder

ones having their apical hook reduced in size and almost

spiniform, in its four anterior tarsi being more narrow and

linear, whilst the hinder pair are comparatively robust, and

in its claws being so exceedingly minute as to be barely

traceable even beneath the microscope. In its general

outline and sculpture, as well as in its rather pallid hue, it

is exactly intermediate between Pentatemnus and Ony-

cholips,—a fact which is equally borne-out by its nearly

rudimentary ungues, and the somewhat spiniform struc-

ture of its hinder tibial wnez.

In its prothorax being appreciably narrower than the

elytra, as well as in its inner tibial angle being produced

into a very evident, robust spinule, and in its eyes being

totally absent, Haloryhnchus embodies some of the most

characteristic features, likewise, of Lipommata (in the true

Cossonides),—thus bearing still further testimony to that

strange and mysterious resemblance which seems, as it

were, to bind together the whole of these immediate pilose,

posteriorly-asperated, fossorial, sand-infesting forms, in the

three subfamilies Pentarthrides, Onycholipides, and Cos-

sonides.

31. GrorRHYNCHUS (Roelofs, Ann. Soc. Belg. x. 241.

1866; and xi. 78. 1867).—I am indebted to M. Roelofs,

of Brussels, for the opportunity of examining his unique

type of the very curious insect (captured near Montevideo,

in South America) for the reception of which he established

the present genus; and although I will not venture to re-

cord more than a desultory opinion concerning its affinities,

which Lacordaire (vide Gen. vii. 348, note) and others

have justly regarded as very obscure; yet, after a careful

examination of its several parts, I cannot but think that it

528 Mr. T. Vernon Wollaston on the

is perhaps more correctly placed at no great distance from

the equally anomalous group Onycholips than in any other

situation with which I am at present acquainted. And if

it can be shown that the subfamily Onycholipides is its

true status, there can be but little doubt (despite the

anomalousness of its structure) that it is a veritable mem-

ber (although, like its immediate associates, an aberrant

one) of the Cossonide;—for Onycholips is so intimately

connected, on the one hand (through Halorhynchus and

Pentatemnus), with the Pentarthrides, and on the other

(by means of Raymondionymus, Alaocyba, and Lipom-

mata) with the Cossonides proper, that there is scarcely

room for question as to where, in any system of arrange-

ment which professes to be a natural one, zt should be

stationed.

Although very differently modified, there is a remark-

able degree of correspondence between Georrhynchus and

Onycholips,—not merely in the exact parts selected for

modification, but likewise, to a certain extent, even in the

kind of their development ; whilst in their subfossorial,

sand-infesting modes of life they appear to possess another,

and a very significant, pomt of union. Thus, in both

cases, the number of the funiculus-joints is reduced to the

very unusual one of siz, and that of the tarsal ones to four ;

and: both genera are almost equally conspicuous for their

comparatively pale, hairy, convex, and slightly asperated

bodies; for their greatly abbreviated antenne, rostra, and

metasterna; and for their tibie (although different in

detail) being on a compressed and burrowing type, and

moreover (which is of the utmost importance) free from

an apical hook. In each instance, too, the scutellum is

distinct, and (which is especially to be noted) the front

cox are contiguous and the intermediate ones but barely

separated. It is true that the eyes and claws, which are

absent in Onycholips, are present in Georrhynchus; but

that may indicate a mere generic difference, such as we

see paralleled in other groups of the Cossontde which are

universally admitted to be in juxta-position; and I think

therefore that enough has been said to render it at least

probable that the two genera in question are not very

remote, as regards the several peculiarities of their struc-

ture, from each other. And if this fact can be but once

established, it seems to me that we have then sufficient

evidence to show (as may be gleaned from my observations

Genera of the Cossonide. 529

under Onycholips and the following groups) that the true

position of Georrhynchus must be, of necessity, amongst

the Cossonids.

32. OnycHo.irs (Wollaston, Trans. Ent. Soc. Lond. v.

389. 1861).—It was not without some degree of hesitation

in the first instance, that I decided on recognising the

anomalous genus Onycholips as the type of a subfamily

of the Cossonide; more especially since Lacordaire has

expressed a doubt as to its true location, and hints that

it may perhaps be necessary to establish a distinct family

of the Rhynchophora to receive it,—along perhaps with

Georrhynchus (the almost equally unintelligible Curcu-

lionid just alluded to, with apparently somewhat similar

subfossorial habits, detected at Montevideo). Yet, de-

spite its many eccentricities, some of which would seem to

debar it from nearly every department of the weevils which

has hitherto been defined (and which must remain, con-

sequently, anomalies wherever the genus be placed), the

more I study its various details (structural and external),

and its fossorial mode of life, the more convinced am I, as

at first, of its not very distant relationship with such blind

members of the Cossonide as Pentatemnus, Halorhynchus,

and Lipommata (particularly the former), and even more

so perhaps with the equally blind Raymondionymus and

Alaocyba,—all of which have either burrowing or sand-

infesting habits, and slightly pilose bodies, and which show

some kind of tendency for unusual tibial developments; the

last two, moreover, having a 6-jointed funiculus, and

quadriarticulate feet. Perhaps the most significant points

however, which have been urged as tending to remove it

from the Cossonide are embodied in the twofold fact that

its first and second abdominal segments are not completely

soldered, and that its intermediate coxze are almost (like

the anterior ones) contiguous; but, on the other hand,

there are many undoubted Cossonids in which the first

and second segments of the abdomen are not absolutely

confluent, being (as in Hexarthrum, Brachytemnus and

Spherocorynes) separated from each other by a most con-

spicuous sutural line; whilst certain, also, of the sub-

Hylastideous genera of the true Cossonides have (like

Hexarthrum, Stereocorynes, Tomolips, Brachytemnus,

Stenoscelis, and others) their intermediate legs (no less

than their anterior ones, almost completely in contact, and

I think therefore that neither of those characters will

530 Mr. T. Vernon Wollaston on the

suffice, of itself, to exclude a manifestly erratic form like

Onycholips from being regarded as the type of a new

department of the present family, the exponents of which

are thus anomalously (though variously) modified.

Apart from its totally blind condition, its 6-jointed funi-

culus* and quadriarticulate feet, as well as from the fact

of its anterior cox being entirely and its intermediate

ones almost contiguous, and its apparent freedom from

tarsal claws, Onycholips is at once remarkable for its

rather globose and testaceous body, which is sparingly

beset with exceedingly long silken pile, and the surface of

which is somewhat wneven (being marked, or pitted, with

large but shallow varioles, or irregular punctiform impres-

sions) and slightly asperated, for its rostrum being short,

broad, depressed, and subtriangular, for its scutellum being

distinct, and for its antennz and legs being greatly abbre-

viated. Indeed, the former are of a most curious struc-

ture, their scape being so reduced in length as to be

absolutely concealed within the short and deep auriculiform

scrobs ; whilst its funiculus has the first two (!) articula-

tions very largely and subequally incrassated, with the

remaining four minute; and their club is extremely solid,

and apically-pilose. And the latter, which are very short

(especially as regards their femora), are still more extra-

ordinary,—the two front tibize being produced at their

outer angle into an exceedingly elongated, tectiform lobe

(which represents the ordinary hook); whilst the four

hinder ones are powerfully developed, and spinulose along

their exterior edge, and compressed at each of their angles

(inner and outer) into a small obtuse lobiform plate,—

between which the feet are implanted. ‘These latter are

on a pattern which is quite without precedent in any

Coleopterous insect with which I am acquainted: for

while the anterior pair are abnormally shortened, narrow,

filiform, and quadri-articulate (the fifth joint being appa-

rently lost, and the fourth, or terminal, one being sur-

mounted by a tuft of elongate pile as though to represent

the ungues), the remaining ones have their basal joint

abbreviated, the two following produced into a divaricating

spiniform lobe at each of their angles, and the fourth, as I

believe, minute and completely soldered to, or merged into,

the fifth (which, like those which precede it, is apically-

Onycholips as possessing a 7-jointed funiculus.

Genera of the Cossonide. 531

divaricate),—the two together thus constituting a single

joint, bifurcated at its tip. And from the analogy of the

similar (though more enlarged) lobes at the angles of the

joints which precede it, I conclude that these two terminal

diverging processes do not represent the claws (which seem

to be altogether absent), but rather the prolongations of

the anterior angles of the ultimate joint.

In its habits Onycholips appears to be much the same

as Pentatemnus and Lipommata, though more decidedly

fossorial,—its spinulose posterior tibiz bemg eminently on

a burrowing pattern; and it is still more conspicuously

beset (like so many sand-infesting insects), with remote,

elongated hairs. Indeed, these latter are not confined to

the body alone, both the scape and club of the antennz

being singularly pilose. I have captured it in the three

eastern islands (Lanzarote, Fuerteventura, and Grand

Canary) of the Canarian archipelago,—where it resides

on, and beneath, the surface of the sandy hillocks, in the

vicinity of the coast, which have accumulated gradually

around the roots of the few shrubby plants which stud

those arid spots.

33. RAYMONDIONYMUS (= Raymonpi4, pars, Aubé,

Ann. de la Soc. Ent. de France, 195. 1861).— The

blind and anomalous genus Raymondionymus (or Ray-

mondia*), which appears to occur in Mediterranean lati-

tudes, has somewhat the fusiform outline, rather elongated

rostrum, and rufo-piceous hue of Amaurorrhinus ; but its

funiculus is composed of six articulations (instead of only

five), its metasternum is shorter still, its tibize (which have

no terminal hook) are compressed and triangularly dilated,

and its feet are short, broad, and thick, furnished with long

* T regret that it should be absolutely necessary to change the name of

this genus,—“ Raymondia’’ having been preoccupied by M. Frauenfeld, for

a group of the Diptera (vide Sitzungsb. d. Wien. Acad. xviii, 320), six years

before it was employed by Aubé. In real fact, however, this is perhaps

the less to be deplored, since I strongly suspect (judging from the diagnosis

and figure) that Aubé’s &. fossor is not actually congeneric with the larger

species which haye subsequently been associated with it,—but more properly

with Alaocyba, as recently enunciated by Perris; and if this should be the

case, it follows that the larger species, of which I would regard the 2. Mar-

queti as the type, have not yet been separated generically from the smaller

ones. Be this however as it may, the title “ Raymondia” must of neces-

sity be altered; and therefore, being unwilling to disconnect the group

with the name of the eminent Coleopterist to whom it was originally dedi-

cated, I have (rather than take the opposite alternative) proposed for it,

instead, the perhaps not altogether euphonious one of Raymondionymus.

532 Mr. T. Vernon Wollaston on the

hairs beneath, and (instead of being on the ordinary pseu-

dotetramerous type) strictly four-jointed. Its sculpture

is very peculiar, the punctures (which are lighter towards

the apex of the elytra) being exceedingly large and few in

number (somewhat after the fashion of what obtains in

Onycholips); its rostrum (as in Alaocyba and Lipom-

mata) is appreciably, and gradually, narrowed in the

middle ; its surface, although appearing at first sight to

be quite bald, will be seen beneath a high magnifying

power to be studded (at any rate behind) with a few short

bristles ; and its legs are eminently fossorial,; and greatly

incrassated,—the triangularly expanded tibize being deeply

scooped-out, or emarginate, towards their external angle,

the excavation being more or less filled-up, or pectinated

(at any rate in the posterior ones), with strong ciliz, or

bristles. Its antennz (which are elongate, and almost

terminal as regards their insertion) have the second joint

of their funiculus perceptibly, though slightly, longer than

those which follow it, and their club excessively large,

abrupt, and distinctly annulated; and its tarsal claws are

considerably developed. The concave, or longitudinally

impressed, structure, also, of its first and second abdominal

segments should be noticed; but this I think has been

made too much of as a peculiarity,—since the same feature

exists (more or less expressed) not only in Alaocyba, but

likewise in several genera of the Pentarthrides, such as

Amaurorrhinus, Microxylobius, Acanthomerus, and Lam-

prochrus ; and we also find it in Cotaster, of the true

Cossonides. In no genus, however, that I have yet

examined, is the concavity so deep, and so well defined,

as it is in Raymondionymus. In their modes of life the

species of Raymondionymus seem to be in entire accord-

ance with the members of the present curious subfamily,—

their compressed, dilated, setulose, apically unarmed tibize

indicating fossorial habits ; whilst their total freedom from

eyes would tend still further to imply a partially subter-

raneous propensity. And it is not surprising therefore

that the few which have hitherto been brought to light

(principally in the south of France) should have been met

with in such situations as beneath stones deeply imbedded >

in the soil, within crevices of clay, and in the nests of

ants. I should add that the particular species from which

my diagnosis is compiled, and for a type of which I am

indebted to John Gray, Esq., is the R. Marquet?, Aubé,

from Narbonne.

Genera of the Cossonide. 533

34. ALaocyBa (Perris, in Abeille, vii. 31. 1870).—

I am indebted to Dr. Sharp for a type of the very rare

genus Alaocyba,—namely the diminutive A. carinulata,

which was taken by M. Raymond in Sardinia; and, after

a very careful inspection of its details, I feel satisfied that

it is truly distinct from Raymondionymus as represented

by the larger species which have been referred to that

group, though I am less convinced that it differs generi-

cally from the smaller ones which are equally cited as

Raymondie (or Raymondionymi). Indeed one of them,

the “ R. Delarouzeet,” which has been communicated by

John Gray, Esq., appears to me to possess all the essential

characters of Alaocyba, as contradistinguished from Ray-

mondionymus ; and I have no hesitation therefore in

regarding it as pertaining to the former, rather than to the

latter; and it is not unlikely that one or two of the others,

when properly overhauled, may prove to be Alaocybe.

Be this however as it may (for I have had no opportunity

of examining them), I consider the carinulata and Dela-

rouzeet as at any rate belonging to Alaocyba, and the

much larger, darker, and in many respects differently

constructed, Marqueti as a Raymondionymus proper ;

and it is on this understanding that I have compiled my

diagnoses of the two groups.

As thus defined, Alaocyba may be said to differ from

Raymondionymus in the much smaller size, extremely

pallid hue, and more depressed (and perhaps rather more

setulose) bodies of the insects which compose it,—in which

moreover the sculpture is less coarse (particularly in the

A. carinulata, which must be regarded as the type), the

prothorax is furnished with a more evident medial line, or

keel, and the elytra are free from the cariniform structure

(on either side) towards their apex. And, moreover

(which is of greater importance still), the funiculus joints

are more decidedly moniliform (the second one being as

short and rounded as those which follow it), the legs are

less thickened, and the tibiz are less broadly dilated,—

especially the front pair, which are noé scooped-out like

the other four towards their external apex, but merely a

little truncated. The rostrum, too, is proportionately not

quite so elongate ; and in the A. carinulata the antennze

are implanted a trifle further from its apex. In their

habits the Alaocybe appear to be very similar to the

Raymondionymi,—the structure of their compressed tibiee,

although a little less strongly pronounced, being eminently

534 Mr. T. Vernon Wollaston on the

fossorial. The A. carinulata, which (as just stated) is

the type of the genus, was detected by M. Raymond in

Sardinia.

35. Lipommata ( Wollaston, Cat. Mad. Col. 100. 1857).

—In the relative length and shape of its (nevertheless

thicker) rostrum, which (instead of being quite parallel) is

rather contracted in the middle, as well as in its total

freedom from eyes, its sparingly pilose surface, obsolete

scutellum, and subfossorial mode of life, Lipommata has

manifestly more in common (despite its comparatively large,

convex, Phlwophagus-like body) with Raymondionymus

and Alaocyba of the preceding section (in which neverthe-

less the funiculus is 6-jointed, the feet quadriarticulate,

and the tibial hook absent) than Cotaster has; and there-

fore I have given it the first place in the Cossonideous

division of the family ;—though at the same time it is true

that in Cotaster the greatly abbreviated metasternum, un-

even prothorax, and primd facie aspect would indicate a

considerable affinity with those two genera. In reality,

however, I believe that Lipommata is still more closely

connected with the (equally subfossorial) Pentatemnus, of

the Pentarthrides,—which it greatly resembles, both in

appearance and habits; but, not to mention other points

of dissimilarity, that genus has the funiculus only 5-

(instead of 7-) articulate, and the eyes (instead of being,

as in Lipommata, altogether wanting) merely obsolete. At

first sight, indeed, Lipommata might almost be regarded

as a blind Phlwophagus,—so greatly does its ovate outline,

obsolete scutellum, and convex, pilose surface, agree with

certain members of that group: nevertheless its total free-

dom from eyes, its minutely asperated, basally-subemar-

ginate elytra (the shoulders of which are, consequently,

somewhat unusually porrect), and its rather differently-

developed tibiz, will of themselves at once separate it from

the Phleophagi. The single exponent of it which has

hitherto been brought to light seems to possess the same

sand-infesting propensities as Pentatemnus and Onycholips;

it having been detected by myself in the Madeiran archi-

pelago,—where it occurs about the roots of certain plants

(often at a considerable depth beneath the surface), on the

sandy slopes behind the sea-beach, in the island of Porto

Santo. It is the only true member, so far as I am aware,

of the subfamily Cossonides, in which the organs of sight

are completely wanting.

Genera of the Cossonide. 535

36. STYPHLODERES (nov. gen.; Coraster, Mots.,

pars).—In its exceedingly abbreviated metasternum,

obsolete scutellum, and elongated antennz (which are

implanted considerably before the middle of the rostrum),

as well as in its more or less pallid hue and subelliptical

elytra, Styphloderes has much manifestly in common with

Raymondionymus and Alaocyba, of the preceding sub-

family; nevertheless it differs very essentially from them

both, not only in its much larger size, and in its funiculus

being 7- (instead of 6-) articulate, but likewise in its eyes

being developed, and in the structure of its much longer

legs,—the tibize of which (instead of being spinulose, com-

pressed, fossorial, and apically unarmed) are elongate,

narrow, and (as in all the Cossonide except the Notio-

mimetides and the Onycholipides) uncinated at their outer

angle; whilst the feet, instead of being simple and quadri-

articulate, are on the ordinary pseudotetramerous type,—

the third joint being expanded and bilobed, and the fourth

one minute and hidden. With these most important dis-

crepancies, it seems to me quite impossible (despite the

opinion of Lacordaire) to admit Styphloderes into the

same actual section as those two genera; yet I have never-

theless acknowledged the points of agreement between the

three (which consist mainly in their much-abbreviated

metasternum and pallid hue) by placing them almost in

juxta-position,—namely at the end and nearly at the

beginning, respectively, of two distinct subfamilies. In

its mode of life, no less than in its structural details,

Styphloderes does not appear to be fossorial ; though it is

nevertheless stated by Motschoulsky (vide Guér. Rev. de

Zool. 427. 1851) to have been found beneath marine

rejectamenta on the sea-shore near Marseilles. It belongs

essentially to Mediterranean latitudes, having been captured

in the south of Europe and the north of Africa.

The only member of this genus with which I am

acquainted (viz. the exsculptus, Boh., or littoralis, Mots.)

has been hitherto associated with Cotaster; but if we are

to regard the Phleophagus uncipes, of Boheman, as the

type of the latter (and it is expressly stated to be so), it

seems absolutely necessary to propose an additional group

to receive the former,—which differs essentially, in nearly

every one of its details, from the uncipes. Thus, not only

is it larger, and more pallid and depressed, but its rostrum

is relatively very much longer, and rather narrower, its

eyes are considerably smaller, its prothorax is uneven,

536 Mr. T. Vernon Wollaston on the

tricarinated, and constricted in front (instead of being

convex and simple), its antennez are more elongated and

slender, inserted nearer to the apex of the rostrum, and

with the (less compact) funiculus-joints (especially the

second one) longer, its legs also (particularly as regards

the tibiz) are longer and thinner, and its feet have the

third articulation more evidently expanded and bilobed,

and the claws conspicuously more developed. The body

moreover, instead of being coarsely, though sparingly,

pubescent (with the pubescence developed on the elytra

into elongate, erect sete), is bald.*

37. CorasTER (Motschoulsky, Guér. Rev. Zool. 425.

1851).—In prima facie aspect this is one of the most

remarkable genera of the Cossonide with which I am

acquainted; and, although European, it appears to be

somewhat scarce in collections. Iam however indebted

to Mr. Gray and to Mr. E. W. Janson for the opportunity

of examining several types—which, judging from labels

which are appended to them, appear to have been

captured by M. Hampe in Croatia. Before an accurate

inspection, it has much the appearance of a small and

rather narrow Acalles,—its convex, ovate body, and nearly

opake, reddish-brown surface (which is sparingly clothed

with decumbent fulvo-cinereous pile, which however is

developed on the alternate interstices of the elytra into

elongate erect bristles), giving it a character which is

strongly suggestive of certain members of that group. Its

rostrum is rather long and cylindrical; its prothorax

(which is narrower than the elytra, at any rate than the

widest portion of them) is suboval, closely punctured, and

even (being scarcely at all constricted behind the apex);

its elytra are ovate and punctate-striated, with the inter-

stices convex and remotely studded (at any rate as regards

the alternate ones) with the elongate seta to.which I have

above alluded; its antenne (which have their scape robust,

shghtly curved, and considerably thickened towards the

apex, and their second funiculus-joint not at all lengthened)

are inserted a little before the middle of the rostrum; its

legs are a good deal incrassated; its claws are exceedingly

* I have had no opportunity of inspecting the cuneipennis, Aubé ;

but, judging from the diagnosis, my belief is that it will be found to be a

true Cotaster (and therefore congeneric with the wncipes), and not refer-

dee to the group which I have established for the reception of the ea-

sculptus.

minute; its metasternum is very short, and the first seg-

ment of its abdomen is likewise more abbreviated than is

usually the case amongst. the Cossonide.

[38. LymanrTEs (Schénherr, Gen. et Spec. Curc. iv. 1085.

1838 ).—The present genus, together with the two follow-

ing, I have not been able to inspect; and consequently

the few diagnostic characters which are given of it in my

summary I cannot vouch for as being in precise accordance

with the type. It seems to have been founded on a single

species, from North America,—the S. scrobicollis, Bohm,

—which is described as rather elongate and oblong, of

either a black or brownish hue, somewhat variolose an-

teriorly and beneath, and with the elytra (which are not

wider than the prothorax) deeply punctate-striate. Its

metasternum is much abbreviated; its rostrum is robust,

and separated by a deep stricture from the forehead; its

eyes are small and depressed; its prothorax is elongate-

_ quadrate; and its feet are short and filiform. |

_ [39. Aparoprion (Hampe, Wien. Ent. Monatsch. v.

68. 1861).—As just stated, this genus (although Kuro-

pean) I have not been able to procure for examination ;

and consequently I cannot speak with any precision con-

cerning the very few diagnostic features which I have

extracted concerning it from Lacordaire. Indeed even

the latter does not appear to have been acquainted with it

except through the very short and imperfect description

given by M. Hampe; and we may presume therefore

that it is of great rarity in collections. It was established

to receive a small insect (the A. costatum) from Tran-

sylvania, which is said to be of a brownish colour and

finely pubescent,—with the prothorax subglobose and much

narrower than the elytra (which latter are oval and con-

vex), the head minute, the rostrum (into which the an-

tennz are inserted towards the apex) rather long and

subcylindric, and the third tarsal joint bilobed. |

[40. OopEmas (Boheman, Res. Fugen. 138. 1859).—

This genus, like the two preceding ones, I have not been

able to inspect ; and my short diagnosis is, consequently,

a mere epitome of the one given by Lacordaire. It ap-

pears to have been founded by Boheman to receive a small

insect taken near Honolulu, in the Sandwich Islands;

and of a greenish-brassy tint,—somewhat resembling, at

first sight, according to Lacordaire, my Pentarthrideous

Acanthomerus conicollis, of St. Helena. It appears to be

very slightly sculptured anteriorly, but with the elytra

longitudinally punctured (the punctures being large in

front, but evanescent behind); its rostrum is said to be

short and cylindrical, with the antennz (which are slender)

inserted at about the middle point; its anterior cox are

but feebly apart, and the third joint of its feet is large and

bilobed. |

.41, CavLorruris (Wollaston, Zns. Mad. 308. 1854).

—In a paper which I published, in 1861, on the ‘ Atlantic

Cossonides,’ I expressed a doubt (vide Trans. Ent. Soe.

Lond. v. 375) as to whether Caulotrupis should be re-

garded as more, in reality, than a slight geographical

phasis of Phleophagus peculiar to the Madeiran archi-

pelago; and Lacordaire, taking advantage of this hesita-

tion on my part, did not scruple to cite it (Gen. des Col.

vil. 342) as absolutely identical with that group. Yet a

more critical inspection of it than I had formerly been able

to bestow has convinced me, as at first, that it will be

better to treat it as generically distinct,—more especially

since the presence, at the same time, of Phleophagus

proper in the Madeiran islands would seem to imply that

it can scarcely be a local development, at all events, of

that widely-spread type. Moreover the Caulotrupides

play so important a part in the Rhynchophorous fauna of

Madeira, where they attach themselves principally to the

old and decaying stalks of various shrubby plants (though

a few of them occur likewise beneath the bark of timber

trees), that there is an additional advantage in keeping

them separate; and it is with the greater satisfaction

therefore that I am able to detect certain structural cha-

racters which I cannot but think, however small when

taken separately into account, must fully warrant, when

combined, my original conclusions with respect to them.

The Caulotrupides have a peculiar aspect, which, when

once seen, can scarcely: fail to distinguish them, even

prima facie, from the Phleophagi. ‘Thus they are more

elliptical, or fusiform, in outline, much more lightly sculp-

tured (particularly as regards their prothorax), and have,

most of them, a greater or less tendency for a metallic

lustre,—the terebrans, Chevrolatit and conicollis being

completely brassy. Yet, in spite of this, their surface

Genera of the Cossonide. 539

(which for the most part is perfectly bald) is more or less

alutaceous, being in some instances so conspicuously so as

to appear nearly opake. ‘Their prothoraces are more or

less conical, and unmargined along the posterior edge,

their scutella are generally quite untraceable, their pro-

sternum is very distinctly carinulated behind the anterior

cox, their legs are a little wider apart at the base than is

the case in the true Phlwophagi (the hinder pair being

especially remote), and the first joint of their feet is less

evidently elongated.

42, PHiLmopnacus (Schonherr, Gen. Cure. iv. 1047.

1838).—The genus Phleophagus has often been a good

deal confused with Rhyncolus, certain species having been

assigned by different authors to either group according as

their rostra happened to be either slender or robust ; and

indeed if the gracility of that organ were their main dis-

tinguishing feature, it would perhaps be difficult to draw

a line of positive demarcation between the two,—for there

are undoubted members of both genera which have their

rostrum narrow, and others which have it incrassated.

Yet on the average the rostrum is certainly both longer

and slenderer in Phleophagus than it is in Rhyncolus.

There are other characters, however, which would tend

(according to the arrangement which seems to me to be

most natural for the Cossonides) to place the groups in

question far asunder ; and perhaps none is more important

than the presence or absence of a scutellum,—which in

Phleophagus is either altogether untraceable, or else is so

minute‘and punctiform as to be with difficulty detected.

The Phleophagi also are more convex and ovate than the

Rhyncoli; their prothorax is usually less developed, but

more rounded at the sides; their metasternum is appre-

ciably shorter; their anterior coxe are more approximated

(indeed the front ones are nearly contiguous) ; and their

antenne and legs are slenderer,—the former of which,

likewise, as well as the tarsi, are generally more lengthened.

The Phleophagi moreover have the second joint of their

funiculus and the basal one of their feet longer than is

the case in Rhyncolus, and also the club of their antennz

more enlarged and annulated ; and their third tarsal arti-

culation is for the most part minutely bilobed, rather than

simple ;—though this character, last mentioned, is, in both

genera, a variable one. The Phlaeophagi are principally

and some of them have a very faint brassy tinge ; and,

unlike the Rhyncoli, certain of the species (though by no

means the majority of them) are sparingly pubescent.

They appear to be widely distributed over the world ;

and although specifically few in number throughout

Europe, they are rather unusually dominant in some. of

the islands of the Atlantic archipelagos.*

43. PsEUDOPHL@OPHAGUS (nov. gen.).—This genus,

which is established to receive the Phleophagus tenax

from Madeira and the Azores, combines in a remarkable

degree the structural peculiarities of Rhyneolus and

Phleophagus,— agreeing with the former in its more

parallel outline, less inflated body, and conspicuous (though

rather small, transverse, and sub-perpendicular) scutellum ;

but with the latter in its abbreviated metasternum, and in

its comparatively slender antennz and tarsi, the first of

which have (as in Phlwophagus) their second funiculus-

joint appreciably longer than those whieh follow it, and

their club enlarged and abrupt, whilst in the feet the basal

articulation is considerably lengthened, and the third one

minutely bilobed. In its greatly approximated anterior

coxee it is more on the Phlwophagus than the Rhyncolus

pattern, and in its sericeous surface it is likewise more in

accordance with (at any rate a certain section of) the

former ; but its cox are, if anything, still less separated

than in even the Phlwophagi (the front ones being practi-

cally contiguous), whilst the minute keel, or lobe, of its

mesosternum (between the intermediate coxze) appears to

me to be more developed than in either of those groups.

Its type (the P. tenaz) is a very common insect in the

higher elevations of Madeira, where it occurs in great pro-

fusion in the rotten wood, and beneath the bark, of old

trees,—more particularly those of the laurel tribe ; and it

has been met with also in the Azorean archipelago.

* The European P. @neopiceus is a less typical member of the group

than the various other species which I have examined ; for not only does

it recede in outline from the latter, but it has also manifest indications of

a scutellum,—which, although not very easy to be detected, is certainly

appreciable. Indeed, I am not quite sure that it would not be more natural

to admit it (along with the tena, from Madeira and the Azores) into the

genus Pseudophlaophagus ; nevertheless since the characters alluded to are

not very pronounced ones, I will not disturb it in its usually-received

position,

Genera of the Cossonide. 541

44, 'THAUMASTOPHASIS (nov. gen.).—It is for an insect

which was captured at Gawler in Southern Australia, and

which has been communicated by Mr. Pascoe, that the

present genus is proposed; and so remarkable is it in

many of its structural details that I could at first scarcely

persuade myself that it was a member of the Cossonide

at all. But since at least three other forms (outside the

anomalous subfamily Onycholipides),namely Aorus, Lipan-

cylus, and Xenocnema, have the tibial hook obsolete,

and are nevertheless veritable Cossonids, one at any rate

of its most significant features may be regarded as not

altogether unparalleled even in the present department of

the Rhynchophora. And certainly in Thaumastophasis

the tibial uncus is strictly “ obsolete” (and not completely

absent ),—for, when examined beneath a high magnifying

power, its presence may readily be detected in the anterior

pair, and I am not altogether sure that I cannot recognize

traces of it in the four posterior ones likewise (though I

will not be quite positive on this point); whilst the fact of

its front coxze being contiguous, and the intermediate ones

but barely separated, is almost in exact accordance with

what we observe in Pseudophleophagus, and which is like-

wise unmistakeably approached in even Phleophagus

proper.

I need scarcely add that the affinities of T’haumasto-

phasis are extremely difficult; but, nevertheless, having

once decided that it is a veritable member of the present

family, I am inclined to think that it will be better to place

it near to Pseudophleophagus than elsewhere,—with which

(despite its many eccentricities) it agrees at all events in

the shape and proportions of its (rather thick and linear)

rostrum, and in its antennz being long and slender, as

well as in its body (although short) being parallel, seri-

ceous and convex, its metasternum much abbreviated, its

front cox contiguous (or practically so) and the inter-

mediate pair but faintly apart, and in its feet (which how-

ever are considerably thicker) having their basal joint (like

the second one of the funiculus) appreciably lengthened,

and the third one (although very much more conspicuously

so) expanded and bilobed. 5

In other particulars Thaumastophasis is remarkable for

its perfectly enormous eyes (which however are not ex-

tremely prominent), for its slender and acuminated club,

for its prothorax (which is small, and very much narrower

_than the elytra) being slightly uneven, or as it were

malleated, but nevertheless nearly unconstricted in front,

for its legs being a good deal thickened, and for its body

being of a piceous hue, with the exception of the elytra—

which are conspicuously paler, or of a clear rufo-testaceous.

45. Hrmatium (nov. gen.).—In its narrow, parallel,

cylindric, but not very convex, body—which is of a rufo-

piceous hue, and sparingly studded with elongate, partially-

erect, fulvescent hairs—the interesting little Cossonid for

which the present genus is proposed, and which has been

communicated by Mr. Fry as having been received from

Malabar in southern India, will be easily recognized. Its |

surface is slightly shining, and (with the exception of the

head, which is convex and almost free from punctation)

coarsely and very densely sculptured; its rostrum is

parallel, but nevertheless somewhat narrow and not very

elongate; its eyes are depressed, and greatly separated

from each other,—so much so indeed that they are barely

visible when the insect is viewed from above ; its antennze

(which are inserted just before the middle of the rostrum)

have their scape rather abbreviated, straight, and robust,

and their funiculus-joints (with the exception of the first

one), short, subequal, and submoniliform ; its prothorax is

oval, and a good deal constricted in front; its metasternum

is elongate; its coxs (even the anterior pair) are wide

apart, and the third articulation of its feet is nearly

simple.

46. PHOLIDONOTUS (nov. gen.).—I am indebted to

Mr. Pascoe for the loan of the somewhat obscure and in-

significant little insect (captured by Mr. Wallace at

Sarawak, in Borneo) to contain which the present genus is

proposed; and, apart from its rather diminutive size, and

piceous, opake, densely-sculptured surface, it is remark-

able amongst the Cossonide for being one of the very

few forms the surface of which is clothed (as in Pholido-

forus from Japan) with scales,—some of them being coarse

and mud-like, and others thick, robust, and setiform. In

. the inferior position of its depressed eyes (which are

scarcely visible when the specimen is viewed from above),

as well as in the structure of its rather long and narrow,

but straightened, rostrum, and in the fact of its surface

being piceous and (at any rate) clothed, I think there can

be little doubt that it displays a certain degree of affinity

with the Indian genus Himatium; but, in addition to its

Genera of the Cossonide. 543

squamose covering and smaller stature, its surface is more

opake and closely sculptured, its rostrum is relatively more

elongate and slender, its antennze are more medially in-

serted, its scutellum is much less developed, and its legs

are setose and proportionately thicker,—with the posterior

coxe wider apart, and the third tarsal jot more evidently

bilobed.

47. COPTORHAMPHUS (nov. gen.).—The present genus

is founded on two species which have been communicated

by Mr. Pascoe (obtained, I presume, by Mr. Wallace),—

one of them from Sarawak in Borneo, and the other from

Java. Its affinities are extremely difficult to determine ;

nevertheless I believe it to be a member of the Cossonide,

and am inclined to think that the rather inferior position

of its transverse and greatly depressed eyes, in conjunction

with the fact that its rostrum is conspicuously divided

from the forehead, and its surface clothed, or setulose

(though in one of the representatives very sparingly so),

will tend to place it at no great distance from Himatium—

an Indian genus (in the collection of Mr. Fry) from

Malabar. Yet its rostrum is considerably longer, slenderer,

and more curved than that of Himatium, and also very

much more separated from the head, the extreme base

being far more constricted than what we observe in the

groups around even Catolethrus; and its body, instead of

being pubescent, is more or less scaly and setulose. Cop-

torhamphus moreover is remarkable for many peculiarities

which are not indicated in any of the types with which I

have nevertheless considered it the most natural to asso-

ciate it. Thus, for instance, its funiculus (which has the

second joint appreciably elongated) is gradually much in-

creased in width, causing the club, although large, to be

by no means abrupt; its front coxe are nearly, if not in-

deed altogether, contiguous (even more so than in Phle@o-

phagus); its femora are armed beneath with an acute

tooth ; its tibiz are greatly curved, and are furnished to-

wards their outer apex (more or less evidently), with a

pectinated tuft of sete; and its prothorax has a large,

rounded, sharply-defined, and deep fovea just behind the

middle of the disk. This last-mentioned character is so

unusual, that I at first thought it must be the result of

accident ; but since it is conspicuous in both of the species,

I cannot but regard it as a generic eccentricity.

544 Mr. T. Vernon Wollaston on the

48. APHANOMMATA (nov. gen.).— The insect which

constitutes the type of the present genus was taken by

myself, from out of rotten Euphorbia-stems, in the island

of St. Antonio of the Cape Verde archipelago ; and, to a

certain extent, it combines in a remarkable degree the

characters of Phlaophagus and Rhyncolus,—agreeing

with the former in its comparatively slender limbs, and its

more elongated first tarsal and second funiculus joints, as

well as in the fact of its club being abrupt and its eyes

depressed; but with the latter in its body being less con-

vex and more parallel, its rostrum shorter and thicker, its

scutellum conspicuous, and in the greater length both of

its metasternum and (more cylindrical) prothorax. It

possesses, however, many distinctive features of its own, in

which it recedes from both of those genera,—such, for

instance, as the inferior position of its small and sunken

eyes (which are scarcely visible when the insect is viewed

from above), its narrower and more parallel outline, and

its greatly elongated metasternum ; in all of which respects

it approaches far nearer to Himatium. And it is further

remarkable for its black, shining, and completely bald

surface, for its triangular (though, at the same time,

somewhat elongate-triangular) rostrum, for its transverse

scutellum, and for the third articulation of its exceedingly

long and slender feet being small and simple.

49. BRACHYSCAPUS (nov. gen.).—The affinities of this

curious genus (which is founded on an insect from Natal

which has been communicated by Mr. Fry) are somewhat

obscure ; for while it possesses the short and triangular

rostrum, the rather approximated eyes, and the greatly

abbreviated scape of certain of the sub-Hylastideous forms

of the Cossonides, I nevertheless do not believe that it has

in reality anything to do with those particular genera,—

its completely suffused first and second abdominal seg-

ments, and the exact degree of separation of its cox, no

less than the structure of its funiculus and elongate,

conspicuously annulated club, its external contour and

sculpture, and the shape and proportions of its prothorax

(which is regularly oval, and distinctly narrower than the

elytra), being all of them far more on the pattern which

obtains amongst the Phlwophagi. And moreover, when

we further consider that there is a considerable approach

to its peculiar shape of rostrum in the preceding genus,

Aphanommata (in which too the surface is shining, bald,

Genera of the Cossonide. 545

and of a deep black), and that a considerable reduction in

the length of the scape is indicated (though to a less

extent) in Himatium, I feel satisfied that the position in

which I have placed it is a far more natural one than

amongst the (more or less asperated, posteriorly-obtuse )

types bordering on the Hylastide. In addition to the

characteristics above mentioned, Brachyscapus has its

scutellum a good deal enlarged, and its under-wings

considerably developed.

50. PH~aorHacosoma (Wollaston, Trans. Ent. Soc.

Lond. 23. 1873).—The present genus is perhaps, on the

whole, somewhat less satisfactorily defined than most of

the others; and I think it is far from unlikely that it may

be found eventually to include more than a single type of

form; yet, being unwilling to multiply genera unneces-

sarily, [ have thought it better to treat it as admitting a

rather wider amount of structural variation than would

seem to be indicated in the neighbouring groups; and we

may possibly therefore regard it, in this particular respect,

as somewhat analogous to Cossonus. It was established

by myself, originally, to receive two slightly discordant

species which had been collected by Mr. G. Lewis in the

Japanese archipelago; and, if I am correct as regards the

material now before me, I might define it as embracing a

number of insects, sometimes a good deal differmg from

each other, which have a wide inter-tropical range, and

which would seem, to at all events a certain extent, to

represent the Phleophagi and Rhyncoli of Kuropean lati-

tudes. Indeed a considerable proportion of them have, I

think, done duty for the former, and are consequently still

cited as such in the various catalogues; but nevertheless

they cannot, strictly speaking, be associated with the

Phloophagi, any more than they can with the Rhyncoli,

—as interpreted by the structural features of the respective

(and universally-acknowledged) types of those two groups.

Thus, whatever be their discrepancies inter se, they recede

essentially from Phleophagus in having a largely developed

scutellum, a comparatively elongate metasternum and pro-

thorax, and in the second joint of their funiculus, and the

basal one of their feet, being conspicuously more abbre-

viated. Moreover they are, on the average, much larger,

less ovate, and less convex, their rostrum is proportionately

more lengthened, and their four anterior coxze are wider

apart. *

546 Mr. T. Vernon Wollaston on the

From Rhyncolus, on the other hand, (with which they

agree better in their more separated coxz, more elongate

bodies, and developed scutellum), the members of Phleo-

phagosoma differ in their very much slenderer and more

lengthened rostrum, in their less thickened and more

medially implanted antenne, which have a larger and

more abrupt club, and in their less prominent eyes. And

they are also larger than the Rhyncoli, and have their

anterior cox (particularly however the intermediate pair)

rather more remote from each other,—though these two

characters are less strongly expressed than they were as

compared with the corresponding ones of Phlaophagus.*

The species now before me, which I should regard as

pertaining to Phleophagosoma, are from Japan, New

Zealand, the islands of the Malay archipelago, Malacca,

Ceylon, Malabar, and southern Africa. The one from

the last-mentioned of those regions (which has been com-

municated by Mr. Janson) has the name “ Phleophagus

ebeninus, Schén.” appended to it, but it scarcely seems

to me to tally with the published diagnosis of that insect.

51. PnoLimpoForus (Wollaston, Trans. Ent. Soc. Lond.

18. 1873).—The present genus was proposed in order to

receive a very singular Curculionid which appears to be

common in the Japanese archipelago,—where it was de-

tected near Nagasaki, in the island of Kushiu, by Mr. G.

Lewis. It is at once remarkable amongst the *‘Cossonide

for the thick, cinereous, bristle-like scales with which it is

densely studded,—a type of clothing with which we are

very familiar in other departments of the Rhynchophora,

but which is of the rarest occurrence in the Cossonids.

In other respects it is conspicuous by its narrowish-fusi-

form outline (which is parallel in the middle, but much

attenuated both before and behind), for its rather elongated

antennz and feet, for its eyes being exceedingly prominent,

and for its third tarsal joint being a good deal expanded

and bilobed.

52. CopropEMA (Wollaston, Trans. Ent. Soc. Lond.

20. 1873).—Like the last genus, the present one was

* In the species of Phlaophagosoma, which I regard as the more typical

ones, the rostrum is of equal breadth throughont; but in others it is either

(as in the P. ewrvirostris from Japan) a little thickened at the base, or else

(as in the P. fusirostris from New Guinea) slightly and gradually so

behind the middle.

detected by Mr. G. Lewis in Japan, — namely, in the

islands of Kushiu and Nipon; and it is remarkable from

bearing a certain prima facie resemblance to some of the

smaller members of Calandra; whilst likewise its deeply

sculptured, besmeared surface, rather elliptic outline, and

costate elytra recall to mind some of the features of the

Dryophthorides: nevertheless its 7-joited funiculus and

pseudotetramerous feet affiliate it at once with the true

Cossonids. In other respects it is conspicuous for its

rostrum being faintly attenuated towards the tip, for its

eyes being exceedingly depressed, for its elytra being

lopped-off straightly at their extréme apex, for its legs

being rather short and robust, for its tibiae (which have

their hook powerfully developed) being armed with a small

though robust spinule at their inner angle, and for its feet

being very short and. filiform,—with their third articulation

not at all expanded or bilobed.

53. ExopemMa (Wollaston, Z’rans. Ent. Soc. Lond.

22. 1873).—The unique insect on which this genus was

founded is, like Coprodema and Pholidoforus, from the

Japanese archipelago,—where it was captured by Mr. G.

Lewis. Its prima facie aspect indeed, and opake, densely

sculptured surface (which is sparingly besmeared with a

sort of dirty-whitish, scaly, mud-like deposit), are so

strongly suggestive of the former that it might well be

regarded, at first sight, as a second member of that group ;

yet when closely inspected it differs so essentially in the

structure of its feet, which are not only much longer but

have their third joint (instead of small and simple) con-

spicuously widened and bilobed, that I cannot but think

that it should be treated as the type of a nearly-allied but

distinct genus. As regards its less important details, its

antenne are a trifle more elongate, and not quite so

medially inserted (being implanted just perceptibly before

the middle of its rather thicker rostrum), its eyes are a

little more developed, its elytra are not at all truncated at

their apex, and its metasternum and legs (especially the

latter) are appreciably longer. Its femora also, at any

rate the anterior pair, are proportionately not quite so

clavate.

54. MELARHINUS (nov. gen.).—The insect from which

the characters for the present genus have been drawn out

548 Mr. T. Vernon Wollaston on the

is anative of Madagascar, and has been communicated by

Mr. Pascoe. It is rather larger in size than the other

members of the immediate department into which I have

admitted it; nevertheless it agrees with them in its surface

being dark, closely sculptured, and opake, and more or less

besmeared with dirty, mud-like scales. In other respects

it is remarkable for its rostrum being broad and depressed,

channeled down the middle, and with the eyes exceedingly

prominent; for its prothorax being appreciably narrower

than the elytra, a good deal rounded at the sides, and very

deeply constricted behind the apex; for its elytra (which,

when viewed beneath the microscope, are most minutely

and very sparingly pubescent) having their somewhat large

punctures arranged in longitudinal rows, but scarcely in

strie ; and for its antenne and legs being much thickened,

—the former moreover having their funiculus-joints very

closely pressed together, or compact, and their club narrow

and not at all abrupt.

55. PstLosomus (2o0v. gen.).— The present genus is

remarkable amongst the Cossonide for the dark and opake

(yet bald and densely punctured) surface of the somewhat

Calandra-shaped insect for the reception of which it is

proposed, and which has been communicated to me—by

Mr. Janson as a native of Ceylon, and by Mr. G. Lewis,

who captured it at Paulo Penang, in the Malay peninsula.

And it is further distinguished by the comparative large-

ness of its prothorax, by its widely-sulcated elytra,_and by

its first abdominal segment (which is more conspicuously

separated from the second one than is usual in this family)

having in the male sex a deep rounded depression in the

centre which is curiously filled up with fulvescent pile.

Its rostrum is rather short, broad, and subparallel, though

a little longer in the males than in the females, with

the antennz inserted at about the middle point; and its

legs (which are robust and a good deal thickened, especially

as regards their anterior femora) have their tarsi consider-

ably developed, — with the ultimate joint elongate, and

furnished with powerful claws.

I have little doubt that the affinities of Pstlosomus are

with such forms as Coprodema and Exodema, from Japan,

—in which the elytra are costate, and the body (although

very much smaller) is equally opake and densely sculptured.

Nevertheless in both of those groups the surface, instead

_of being bald, is more or less besmeared with mud-like

scales.*

56. [Mimus (Fahraeus, Ofvers. Vet. Ak. Forh. 283.

1871).—Not having been able to procure a type of the

species (from Southern Africa) for which the present was

established by Fahraeus, I know nothing whatever con-

cerning either its structure or its affinities,—the former,

if we may judge from the diagnosis, being of the most

commonplace description, and such as might apply equally

to two-thirds of the entire Cossonide ; whilst so far as the

latter are concerned, not a syllable is recorded by Fahraeus

except that the group represents a new. “tribe” of the

family. But why this should be the case it is impossible

to conjecture, seeing that his description does not indicate

so much as a single structural anomaly. Since he speaks

however of the elytra as sulcate (no allusion being made

to punctured striz), and the body as black and closely

sculptured, I am inclined (on the merest conjecture) to

place the genus next to Pstlosomus (from Ceylon and the

Malayan peninsula),—in which the elytra are emphatically

“ sulcated,” and the punctation is altogether dense. |

57. AMORPHOCERUS (Schoénherr, Cure. Disp. Meth.

329. 1826).—The South-African genus Amorphocerus, for

types of which (the A. rufipes, Boh., and the A. zamie,

Boh.) I am indebted to Mr. Pascoe and Mr. Janson, has

many peculiarities of its own,—one of which, namely the

construction of its tibiz, would rather tend to remove it

from the present family. These latter are decidedly

abnormal for the Cossontde,—being not only unusually

broad, triangular, and compressed, but with their apical

hook (understanding that almost universal appendage as

a prolongation of the outer angle) obsolete. Itistrue that

a long and curved spine is conspicuous, but then it does

not proceed from the external angle (which is merely sur-

mounted with a very short and straight spinule); and also

the genus Psilosomus is the one which was described by Mr. Walker (Ann.

Nat. Hist. iv. 218, 1859) under the name of “ Cossonus? hebes; but since

his diagnosis is contained in ten words, and is unaccompanied by a single

remark, it is impossible without an examination of the type itself to decide

this point. But in any case the generic characters have not hitherto been

defined ; and I have thought it worth while therefore, even if the species

should prove eventually to be the one alluded to by Mr. Walker, to place

them on record.

550 Mr. T. Vernon Wollaston on the

that there is a second spine, from the inner angle of the

tibia, of almost equal length, besides an additional smaller

one between the elongated central one and the outer

angle,—an anomalous structure (amongst the Cossonids),

which causes the whole apex to be essentially spinulose.

Yet there is a little indication of an irregularity of (at all

events) partially the same character, in the (likewise

African) genus Aorus and the South-American Lipan-

cylus,—which I have consequently placed in juxta-position

with Amorphocerus, and in which at any rate the terminal

uncus appears (as it seems to me) to be obsolete.

In other respects Amorphocerus is remarkable for its

rather depressed, broadish, parallel-oblong, posteriorly-

obtuse body, dark hue, and very deeply (though not very

densely) sculptured surface ; for its rostrum being parallel

and somewhat robust, though not very long; for its pro-

thorax being largely developed, though not wider (at its

broadest part) than the elytra, and but very little con-

stricted in front ; and for its antenne, which are implanted

considerably behind the middle of the rostrum) being

short and thick,—with the funiculus (the first joint of

which is much enlarged) exceedingly solid and compact,

and the club small and not at all abrupt. Its scutellum is

very conspicuous, and the third articulation of its feet is

considerably expanded and bilobed.

58. LipaANcyLus (nov. gen.).—I am indebted to

Mr. Janson for the loan of the very extraordinary insect

for which the present genus is established, and which is

South-American,—it having been taken, I presume by

Mr. Bates, in the region of the Amazon. I have not the

shghtest doubt that its true affinities are with Aorus from

western Africa,—with which it agrees in the most ano-

malous character (for the Cossonide) of its tibial hook

being obsolete, as well as in its elongated, extremely

slender and cylindrical (though less curved) rostrum, its

narrow, parallel body (which, as in that genus, will be

seen, when viewed beneath a high magnifying power, to

be not altogether bald), in its unconstricted prothorax, its

wide and greatly developed feet (the third joint of which

is much expanded and bilobed), its minute claws, and

in the fact of its long and thickened legs being more

approximated at their base than is usual in the members

of this family. Nevertheless, although approaching Aorus

in so many important respects, Lipancylus has an abun-

Genera of the Cossonide. 551

dance of very remarkable features which are essentially

its own, amongst which the proportions of its abdominal

segments are by far the most significant,—the first and

second of them being less elongated, while the third and

fourth are considerably more so, than is customary amongst

the Cossonids. The shape of its prothorax, likewise, is

very peculiar,—it beg somewhat elongate-quadrate, and

rather wider (if anything) before than behind ; its scutellum

is rather large and squarish ; its elytra are bi-arcuated in

front, and separately rounded-off at their extreme apex;

its antenne are slender; and its tibiw, especially the

anterior ones, are armed at their inner angle with a dis-

tinct spine. The two last-mentioned characters, however,

are almost equally indicated in Aorws.

59. Aorus (Schoénherr, Gen. e¢ Spec. Curc. ii. 253.

1836).—The genus Aorus was established by Schénherr

to contain an insect which is found in western Africa,

and for an opportunity of inspecting which I am indebted

to Mr. Pascoe. It was placed by Schénherr amongst the

Cholides ; and although removed by Lacordaire into the

Cossonide, it is by no means a very typical member (any

more than Amorphocerus is) of the latter,—for its un-

usually approximated coxz, narrow, transverse eyes, and,

as it seems to me (for the example before me is a good deal

mutilated), obsolete tibial hook, are all points of great

significance which would certainly tend to remove it from

the Cossonids. Still, its other features being on the Cos-

sonideous type, I have admitted it into the family ,—content

to call attention to these particular characters (whatsoever

they may be worth) of manifest divergence. In other

respects, Aorus is remarkable for its exceedingly long,

slender, and very arcuated rostrum (into which the antennze

are implanted a little before the middle), for its transverse

eyes being altogether depressed, for the second joint of its

funiculus being considerably elongated, for its tibize (the

four anterior ones of which are armed with a spine at their

inner angle) being sparingly asperated, or muricate, in-

ternally, for its third tarsal articulation being a good deal

expanded and bilobed, and for its claws being unusually

minute. In outline it is somewhat long and narrow,—with

the elytra cylindrical and rather convex, and the pro-

thorax (the widest part of which is, if anything, a little

wider than the elytra) large, convex, regularly oval, and a

good deal (and equally) rounded at the sides.

552° Mr. T. Vernon Wollaston on the

60. HoMALOXENUS (nov. gen.).—I am indebted to John

Gray, Esq., for the very curious little insect, from the

West Indian island of St. Domingo, to receive which the

present genus is proposed; and it is so perfectly distinct

from every other Cossonideous form with which I am

acquainted that I had some hesitation at first in admitting

it into the present fgmily at all; nevertheless the unmis-

takeable structure of its abdominal segments, in conjunc-.

tion with its tibial hook and other details, are sufficient I

think to indicate its affinities. Its distinctly annulated

club however, added to its elongate, slender, straightened,

and longitudinally-strigose rostrum, into which the antennz

are implanted at the apex, are anything but in accordance

with the usual modifications of the Cossonid type, being

prima facie somewhat suggestive of certain groups amongst

even the Lrirhinides,—an analogy which (however super-

ficial) its unt-dentate femora would not tend to invalidate.

But apart from these various peculiarities, Homaloxenus

is remarkable for its rather broad and extremely depressed

body —which is subopake, ferruginous, and sparingly

clothed with a very minute decumbent subcinereous pubes-

cence; for its entire prothoracic disk being very curiously

flattened, or impressed; for its antennz being long and

slender, with the second joint of their funiculus (which is

remarkably lax) conspicuously lengthened; and for its

tibiz (which have their hook very small) being barbed, or

pencilled, at their apex with fulvescent hairs. Its scutellum

is largely developed, its metasternum is somewhat short,

and the third articulation of its feet is much expanded and

bilobed.

61. Srenoris (Wollaston, Ins. Mad. 316. 1854).—

The Madeiran genus Stenotis is founded on one of the

most remarkable little Cossonids with which I am ac-

quainted,—its extremely narrow, elongate outline, pallid

hue, and subdepressed, delicately sericeous surface, added

to the excessive length and slenderness of its rostrum, its

elongated prothorax and metasternum, its thickened legs,

and its unusually widened and deeply bilobed third tarsal

joint, giving it a character essentially its own. Its sub-

sericeous surface indeed, and general structure, show it to

belong, unmistakeably, to the same department as Mesttes ;

nevertheless I believe that its nearest known ally is the

South-American genus ELucoptus, from Brazil and the

region of the Amazon,—with which it has a good deal in

Genera of the Cossonide. 553

common, not only as regards its narrow, parallel, somewhat

flattened, and very minutely sericated body, its elongated,

slender rostrum, its greatly lengthened prothorax and

metasternum (the former of which is very powerfully con-

stricted in front), the conspicuously bilobed third joint of

its feet, and the minuteness of its claws, but likewise in

the smallness of its eyes, and in the curious tendency of

its prothorax to be concave beneath. |

In other respects Stenotis is remarkable for its narrow

and porrected head, for its intermediate coxe being not in

the least degree more remote from each other than the

anterior ones, and for its metasternum (which is remark-

ably convex) being furnished on either side in front with

a minute transverse plait (or perhaps, rather, a cluster of

plaits), which have somewhat the appearance of two

roughened fover. Its antennze (which are medial in the

males, but post-medial in the females) are rather long

and slender, with their second funiculus-joint appreciably

lengthened ; its sculpture is less coarse than in most of the

immediately-allied groups; and its prothorax, as in the

forms around Mesztes and Cossonus, is widely channeled

behind. Its type (the S. acieula, Woll.) is one of the

rarest insects of the Madeiran archipelago, being found

amongst the laurels at a high elevation,—on the foliage of

which it appears to subsist.

62. Evucoprus (nov. gen.).—I am indebted to Mr.

Pascoe for the loan of a female example, and to Mr. Fry

for a male one, of the interesting little insect from which

the characters for the present genus have been compiled.

They are both of them South-American,—the former,

judging from a label which is appended to it, having been

captured (I presume by Mr. Bates) in the region of the

Amazon, and the latter in Brazil (I believe near Rio

Janeiro). In size and outward appearance E'ucoptus has

very much in common with such forms as Pentarthrum

and Stenotrupis; but its funiculus is composed of seven,

instead of only five, joints; and it is clear to me that its

affinities, in reality, are with the types which cluster around

Mesites,—par ticularly with the remarkable Stenotis acicula

of Madeira. I have already called attention to the many

characters which it possesses in common with that insect ;

and I need here, therefore, only state that Hucoptus is

conspicuous for its narrow, parallel, depressed, and piceous

body (the elytra however being of a paler, or more rufo-

554 Mr. T. Vernon Wollaston on the

castaneous, hue), which at first sight appears to be per-

fectly bald, but which when viewed beneath a high magni-

fying power will be seen to be very minutely and spar-

ingly sericeous; for its rostrum (which is just appreciably _

widened towards the apex) being elongated and slender in

the female sex; for its antennz being implanted into the

latter considerably behind the middle; for its rather por-

rected head and depressed eyes; for the sharpness, and

fineness, of its sculpture; for its limbs (particularly the

hinder legs) being somewhat short, its club rather narrow,

and its third tarsal joint bilobed; for its prothorax and

metasternum being a good deal lengthened; and for the

first and second segments of its abdomen (the former of

which, in the male sex, has, apparently, a large and

rounded tubercle in the centre) being separated from each

other by a dz-arcuated line. Its prothorax is free from

a longitudinal groove; and its elytra have their striz

nearly simple, and the interstices somewhat transversely-

reticulated.

63. Mesirrs (Schonherr, Gen. et Spec. Cure. iv. 1043.

1838).—A very careful examination of the various species

from the Madeiran, Canarian, and Cape-Verde archi-

pelagos, which I have bathecue referred to Mesites, has

convinced me that they connot properly be admitted into

that group—as represented by its European members, of

which the M. pallidipennis is the universally-acknow-

ledged type; and therefore I have no choice but to restrict

Mesites to the particular insects (namely the M. pallidi-

pennis and cunipes, and the more recently enunciated

M. aquitanus) which it was originally intended to embrace,

—the M. Tardvi, of western Europe, belonging manifestly

to one of the Atlantic types.

As thus understood, Mesztes may be said to differ from

its more immediate allies (comprised in the two following

genera) in its body being more parallel, cylindrical, and

convex, as well as somewhat more shining; in its pro-

thorax being more strictly oblong (instead of subtriangu-

lar); in its. head being more incrassated, and with the

eyes wider apart; in its male rostrum being shorter, and

relatively more robust and linear,—it being less appre-

ciably widened at the insertion of the antennz ; in the

latter bemg much thicker and more abbreviated, particu-

larly as recards their scape (which is likewise more out-

wardly curved); in its funiculus (the second joint of which

Genera of the Cossonide. 555

is not lengthened) being especially more incrassate, and

its club comparatively small and narrow; in its meta-

sternum being a trifle more elongate; and in its coxe

being a little less widely separated.

64. RHOPALOMESITES (nov. gen.).— The type of this

genus I regard to be the M. Tardii, of western Europe,

—an insect which ranges likewise to the Azores; and

associated with it are several species from the Madeiran

and Canarian archipelagos, two of which (namely the

maderensis, and the Teneriffan and Gomeran persimilis),

although with small distinctive features of their own, may

possibly prove to be, in reality, but geographical modifi-

cations of the Zardii. The members of this group differ

from Mesites proper, chiefly, in their male rostrum being

considerably longer and slenderer, and proportionately a

little more widened at the point where the antennz are

inserted ; in the latter (which are implanted either zz or

before the middle, in that particular sex, instead of

behind it) being very much thinner and more elongate,

with the scape especially, and second funiculus-joint, more

lengthened, and with the club very much larger and more

abrupt; in their head being less incrassated and their

eyes more approximate; in their legs being relatively a

little longer, and rather more widely separated at the base ;

and in the third articulation of their feet being appreciably,

though minutely, bilobed. They are also a trifle less

cylindrical than the true Mesites (having a more evident

tendency to be subfusiform), as also a little less convex,

and not quite so shining ; their prothorax is more trian-

gular (or less oblong), and is more conspicuously channelled

behind in the males and carinated in the females; and

they are often sparingly clothed with an exceedingly

delicate sericeous pubescence.

65. ODONTOMESITES (nov. gen. ).— Two of the (so-called)

Mesites from the Canarian archipelago, and one from the

Cape Verdes, I had long ago detached from the re-

mainder,—making them to constitute a distinct section of

the genus, in which the body is more fusiform and de-

pressed, and the male femora are furnished beneath with

an obtuse anguliform tooth; and it is quite clear, there-

fore, that if the Tardzi and its immediate associates be

TRANS. ENT. SOC. 1873.—PART IV. (OCT.) RR

556 Mr. T. Vernon Wollaston on the

disunited from Mesites proper (as I cannot but think is

absolutely necessary), these three species must likewise

form a separate, though closely allied, group. In their

smaller size, more fusiform outline, and general structure,

they are of course nearer to Rhopalomesites than to Mesttes ;

nevertheless they have a more decided tendency to posterior-

attenuation than even the smaller members of the former,

and (in addition to the subdentate femora to which I have

just alluded) they possess a very peculiar feature in the

fact of their male rostrum being fringed with elongate

fulvescent hairs, on either side, from the point at which

the antenne are inserted to the apex. Added to which,

their rostrum in the opposite sex is less abruptly thickened

at its extreme base; their legs are proportionately a trifle

more incrassated, and the intermediate coxze wider apart ;

and the third joint of their feet is, as in Mesites proper,

quite unexpanded and simple.

The species of Odontomesites, so far as I have hitherto

observed, are attached exclusively to the rotten stems and

branches of the various Euphorbias.

[66. PorTHEeTES (Schonherr, Gen. et Spec. Cure. iv.

1041. 1838).—The genus Porthetes was founded to receive

a Cossonid (the P. zamie, Bohem.) from southern Africa ;

and although I have not been able to procure an example

for inspection, the published diagnosis appears to be suffi-

cient to render its peculiarities intelligible. It is described

as having much the primd facie aspect of Mesites,—the

type being a little shorter, but a trifle wider, than the

Kuropean Cossonus ferrugineus, and of a blackish hue,

with the elytra ferruginous. As in Mesites and its imme-

diate allies, the rostrum (and to a certain extent, even the

antenn) vary according to the sex,—it being in the males

thickened throughout its basal half, with the anterior por-

tion narrow and cylindrical (the exact reverse, be it ob-

served, of what is the case in the forms around Mesites),

but in the females incrassated (as in those groups) at the

extreme base only. Its antennze (which are abbreviated)

are shorter in the females than in the males, and are

basally-inserted in the former sex but medially in the

latter ; and the scape is more powerfully clavate in the

males than in the females. In its third tarsal joint, too,

being somewhat expanded and bilobed Porthetes recedes

from Mesites and Odontomesites, and is more on the

Rhopalomesites pattern. |

Genera of the Cossonide. 557

67. MEGALOCORYNUS (nov. gen.).—It is for the Cos-

sonus depressus and conictrostris, of Boheman, and a

closely allied species (or perhaps only local variety) which

has been communicated by Mr. Janson, all of them from

Mexico, that the present genus is proposed ; and, apart

from every other character, they may be immediately dis-

tinguished from the Cossoni, not only by their largely-

developed club, but by the sexual disparity in the structure

of their rostrum and antennz,—in both of which respects

indeed, no less than in their more evenly and densely punc-

tured prothorax, they are far nearer, in reality, to the

groups around Mesites than to Cossonus.

Not to mention its parallel and extremely flattened body,

Megalocorynus is at once remarkable for the enormous

size and length of its capitulum—which is parallel-oblong,

and densely clothed with a velvety pubescence; and its

scape is peculiar from being somewhat twisted and sub-

compressed,—the inner edge (on account of the abrupt,

but elongate, apical clavation) seeming to be almost

scooped-out, or at any rate sinuated, posteriorly. Its

rostrum, too, in the female sex, is of a very unusual

shape,—being rather short and narrow, but nevertheless

flattened, and gradually a little contracted towards the

base ; whilst in the males it is longer, and dilated ante-

riorly much after the fashion of the ordinary Cossonz.

Its eyes (instead of being transverse) are nearly round ;

its prothorax is somewhat small and abbreviated, and a

good deal rounded at the sides; its elytra (which are

appreciably wider than the prothorax) are parallel and

deeply sculptured, with the interstices almost costate ; and

its coxee (even the front ones) are exceedingly remote. Its

antennz in the male sex are inserted a long way before,

but in the females a long way behind, the middle of the

rostrum ; and they are likewise longer and more robust in

the former case than in the latter, and have their scape

more conspicuously clavate, and their capitulum, if any-

thing, even still more developed.

68. CaToLEeTHRUS (Schonherr, Gen. et Spec. Cure. iv.

1077. 1838).— The genus Catolethrus is composed of

a few elongated (occasionally minute), narrow, somewhat

shining, depressed Cossonus-like insects, of which the

main distinguishing features seem to consist, so far at

least as I am able to detect them, in their rostrum being

(especially in the female sex) rather elongate and slender,

RR2

558 Mr. T. Vernon Wallassan on the

but nevertheless a little, and gradually, widened both

towards its base and apex, and divided from the forehead

by a very appreciable line ; in their eyes being exceedingly

depressed, transverse, and slightly approximated above ;

in their prothorax and metasternum being a good deal

lengthened ; in their scutellum being very conspicuous ;

in their elytra (which are just perceptibly broader than the

prothorax) being deeply sulcated towards the apex—where

they are separately, and minutely, rounded off; in their

antenne and legs (the former of which are inserted con-

siderably behind the middle of the rostrum, and have the

second funiculus-joint exceedingly abbreviated) being rather

short and incrassated ; and in their feet being much thick-

ened, with the third articulation conspicuously dilated and

bilobed. Their four anterior coxz are about equally wide

apart, and the hinder ones are but slightly more remote

from each other.

I am indebted to Mr. Fry, and also to Mr. Janson, for

the opportunity of inspecting types of the C. longulus,

Bohm., from Mexico; and several other species are now

in my possession (all of them South American) from the

exceedingly rich collection of Mr. Fry. My own belief

is, that the genus, as properly defined, is essentially an

American one ; for although it is true that three or four

supposed representatives have been described from the

islands of the Pacific, and elsewhere, I think it is never-

theless far from unlikely that these latter will be found, on

a more critical examination, to pertain to some other

group,—perhaps to Catolethromorphus, or even to the

Pentarthrideous genus Stenotrupis.

69. STENOTRIBUS (nov. gen.).—The type of this genus

is a minute and narrow Brazilian Cossonid (communicated

by Mr. Fry as having been received from Bahia), which

is without doubt very closely allied to Catolethrus—for

one of the smaller members of which it might well at first

sight be mistaken. An accurate inspection, however, will

show that it cannot in reality be associated with the

Catolethri,—from which it differs in its antenne being

inserted into the middle (instead of considerably behind

the middle) of its rostrum; in the latter being more

parallel and cylindric (there being scarcely any tendency

to either an anterior or a posterior thickening), and even

still more conspicuously divided from the remarkably

convex forehead; in its prothorax being extremely elon-

Genera of the Cossonide. 559

gated, less constricted in front, and perfectly even (there

being no traces either of keel or depression); in add its

coxee being subequally apart (even the anterior ones being

widely separated); and in its feet being much less in-

crassated, and with their third joint small and simple.

Its elytra too are more decidedly parallel (or less fusiform)

than in Catolethrus ; its body is less depressed; its colour

is nearly black; and its eyes are so extremely sunken as

to be with difficulty detected.

[70. Prokrcres (Schénherr, Gen. et Spec. Curc. iv.

1080. 1838).— The present genus is one of six which

I have not been able to inspect; but the two species to

contain which it was established by Schénherr, and which

are apparently peculiar to Madagascar, are stated by

Lacordaire to be very similar at first sight to the smaller

members of Catolethrus, and quite as narrow. ‘Their

rostrum however is said to be slenderer and more cylin-

drical; their antennz are shorter and less thickened,—

with the second funiculus-joint longer, and the club larger

and more abrupt ; and their legs are thinner, with the third

articulation of the feet simple and not at all wider than

those which precede it. |

71. PHACEGASTER (nov. gen.).—Although it does not

tally precisely with the diagnosis, I have little doubt that

the insect for which the present genus is proposed is the

Catolethrus nasalis of Boheman, from Brazil. At any rate

several examples are now before me (collected by Mr. Fry

near Rio Janeiro, and in the province of S* Catharina)

which I feel satisfied are congeneric, and I believe also

conspecific, with the nasalis ; but it is nevertheless quite

evident that they cannot be associated with the Catolethrz.

Not to mention their much larger size, they differ essen-

tially from the latter in the form of their rostrum—which

is very much broader, somewhat depressed above, and

eradually (though not very considerably ) widened from its

base to its apex; and the antennz are implanted into it

nearer to the middle point. In other respects, Phacegaster

is remarkable for a great peculiarity in its first and second

abdominal segments —each of which are furnished with

two rounded, acedi-like spaces, filled up with coarse

granules, The two on the basal segment are rather larger

and more widely separated from each other than those on

the second one, and are placed defore the middle; whereas

560 Mr. T. Vernon Wollaston on the

those on the latter are not only more approximate, but are

situated close behind the anterior margin. And there is

also another feature which distinguishes this genus from

every other with which I am acquainted, — namely the

fact that its two hinder femora are fringed beneath, in the

middle, with a narrow edging of short fulvescent pile;

whilst the tibiz (of the same pair of legs) are arcuated,

and furnished on their inner side, towards the base, with a

fascicle of elongated hairs. The legs are thicker than in

Catolethrus, and the spine at the internal angle of the

tibize (especially the four posterior ones) is larger and more

robust.

72. GL@ODEMA (nov. gen.).—The two beautiful insects,

communicated by Mr. Pascoe, on which the present genus

is founded (and which were captured by Mr. Wallace at

Dorey and Saylee in New Guinea), are so remarkably alike

in colour, outline, and sculpture that I cannot feel alto-

gether certain that the very peculiar discrepancy which

they display in the construction of their rostrum may not

be merely sexual ; and if this should prove to be the case,

it follows that they must be treated eventually as members

of a single species. With but a solitary example however

of each of them to judge from, I feel scarcely warranted in

assuming that a character so important and conspicuous

is indicative only of the sex; and I have therefore regarded

them as specifically distinct. The feature to which I

allude is the shape and length of the rostrum,—which in

one of the individuals now before me (and, I may add,

very much the larger one of the two) is gradually widened

towards the tip to a most marvellous extent, whilst in the

other it is but slightly increased in breadth.

In other respects Gleodema is remarkable for the large

size, fusiform outline, and somewhat convex, highly-

polished, almost unsculptured surface of the insects of

which it is composed,—which moreover are anomalously

variegated with red and black (a very unusual combina-

tion amongst the Cossonide). Their head is elongate,

and greatly exserted; their eyes are rounded, rather promi-

nent, and wide apart; their prothorax is convex, and per-

fectly even (being quite free both from depressions and

keel); and their limbs are long, but much incrassated,—

the second funiculus-joint being remarkably shortened,

the club narrow and acuminated, the four hinder tibie (as

in Phacegaster, Exonotus, and others of the immediately-

Genera of the Cossonide. 561

allied forms) armed with a powerful and compressed spine

at their. inner angle, and the feet short and thick, with

their third articulation expanded and deeply bilobed.

Their prothorax, too, (as in the Madeiran Stenotis) ap-

pears to be more or less concave beneath; and their

antenne are implanted either about or a trifle before the

middle of the rostrum.

73. GL@OXENUS (nov. gen.).—It is for an insect from

Madagascar (which has been communicated by John

Gray, Esq. ) that I have proposed the present genus; and

its primd facie aspect and fusiform outline are somewhat

those of'a gigantic, deep-black, highly-polished, and lightly-

sculptured Rhyncolus. When more closely examined how-

ever it will be seen to belong, in reality, to a totally dif-

ferent group,—the robust and peculiarly-shaped spine at

the inner angle of its four posterior tibia, in conjunction

with its much abbreviated and thickened feet (the terminal

joint of which is extremely short and conical) affiliating it,

most unmistakeably, with the types around Glawodema,

Phacegaster, Exonotus,and Pseudocossonus. Its rostrum

is rather broad, depressed, and nearly parallel (though

whether this is equally the case in both sexes I have no

means of judging); its limbs are incrassated and exceed-

ingly robust; the third articulation of its feet, although

greatly thickened, is simple; and the spine at the inner

apex of its front tibiz is marvellously lengthened and de-

veloped,—in which latter respect it differs from every other

Cossonideous form with which I am acquainted. As in

most of these immediate genera, its club is narrow and

somewhat acuminated; but its antennz are inserted a

little more evidently before the middle than is usual in the

majority of its allies.

74, EXoNoTUS (nov. gen.).—A genus the type of which

(captured by Mr. Wallace in the ‘islands of the Malayan

archipelago) is well distinguished by its elongate, narrow,

and parallel outline, cathe large size, and convex, shining

surface,—which is of a deep black, with the anterior por-

tion of the elytra red. Its head aad rostrum are broad,

and of nearly equal width,—the latter (which seems to be

linear in the females, but rather expanded anteriorly in

the males) being somewhat short; its coxe are all of

them about equally separated; its legs are exceedingly

thick and robust; its tibiz (the front pair of which are

562 Mr. T. Vernon Wollaston on the

conspicuously biflexuose) have their apical cavities, for

the reception of the tarsi, unusually large and open; and

the latter (as in most of these immediately-allied forms)

are remarkably short and incrassated, with the third joint

deeply bilobed, and the ultimate one abbreviated and

conical. The prothorax and elytra are very distinctly

margined at their respective bases (the latter of them

likewise at the apex); and, as in the neighbouring groups,

the antennz are thick, with the second funiculus-joint

much reduced in length, and the club narrow and acumi-

nated.

75. Pseupocossonus (Wollaston, Zrans. Ent. Soc.

Lond. 27. 1873).— The genus Pseudocossonus was

founded by myself a short time ago to receive two insects

which were captured by Mr. G. Lewis in Japan; and a

third exponent is now before me, from the collection of

Mr. Pascoe, which was obtained by Mr. Wallace at Dorey

in New Guinea. There can be no doubt, I think, that

its affinities are with such forms as Catolethrus and Phace-

gaster, from America; though still more so with Ezonotus,

from the Malayan archipelago, and the Indian Catolethro-

morphus—with which it agrees in its rostrum being more

parallel, and not divided from the forehead by a basal line,

as well as in the fact of its eyes being rounder, more promi-

nent, and more widely separated, in its prothorax being

perfectly even (or free alike from keel and depression), in

its elytra being entire at their extreme apex, and in its four

posterior coxze (instead of the four anterior ones) being

equidistant. As in most of the allied groups, the tibiz of

Pseudocossonus are furnished at their inner angle with a

rather robust spinule; and the feet are abbreviated and

thick, with the third joint bilobed, the terminal one very

short and conical, and the claws exceedingly minute.

Indeed this shortness of the tarsi is even still more ex-

pressed in Pseudocossonus than it is in any of the genera

to which I have above alluded,—the basal and ultimate

articulations being greatly reduced in length. Its body is

shining, nearly parallel, and slightly depressed; and the

sculpture anteriorly and underneath is somewhat fine.

Although usually dark, its elytra (which do not appear

to be margined at their extreme base, or at their apex)

are occasionally rufo-castaneous, especially in front,—a

peculiarity of coloration which is equally indicated in

Exonotus.

Genera of the Cossonide. 563

76. CATOLETHROMORPHUS (nov. gen.).—The present

genus is founded on a single example from the East Indies

(I have no note as to the exact region) which has been

communicated by Mr. Fry; and we may perhaps look

upon it as the Asiatic representative of the American

group Catolethrus, to which in external aspect and struc-

ture it is a good deal allied. Yet it manifestly cannot be

associated with the Catolethri, the most essential features

of which (as regards rostrum, eyes, and antennz) it does

not possess. Thus, not only is its rostrum thicker and

more strictly parallel (there being no indication of the

slight, and gradual, widening towards the base and apex

which is so characteristic of that group), and undivided

by a frontal line from the head, but the latter is more

exserted and largely developed, and has the eyes (instead

of transverse, subapproximated, and depressed) rounded,

comparatively wide apart, and slightly prominent. Its

prothorax also is considerably shorter (being more trun-

cated both before and behind), as well as more even and

convex,—there being no trace of either a keel in front, or

of a groove-like depression behind; its elytra are more

strictly parallel, and entire (instead of separately and

minutely rounded-off ) at their apex; its antenne (which

are inserted in the middle of the rostrum, instead of con-

siderably behind it) have their scape very much longer,

and their club more abrupt and less acuminated ; and its

intermediate coxee are more remote. This last-mentioned

peculiarity has a certain importance amongst these imme-

diate groups,—occasioning the four posterior legs (instead

of, as in Catolethrus, the four anterior ones) to be equi-

distant at their base.

77. BRACHYCHENUS (nov. gen.).—In its rather narrow,

parallel, and depressed body (which is of a palish, rufo-

ferruginous hue), as well as in its linear and somewhat

robust rostrum, its even prothorax, and the fact of its

four posterior legs being subequally distant at their base

(oceasioned by the intermediate pair being rather wider

apart than is usual), the little Cossonid from which the

details for the present genus have been compiled, and

which has been communicated by Mr. Pascoe as having

been taken by Mr. Wallace at Sarawak in Borneo, has a

good deal in common with Catolethromorphus ; neverthe-

less its type is very much more minute than that of the

latter, its rostrum is relatively not so elongated, its

564 Mr. T. Vernon Wollaston on the

antenne (which are inserted rather behind the middle,

instead of at the middle point) have their funiculus much

shorter, as well as more robust and compact, with the

second joint so greatly abbreviated that it is almost con-

cealed from view, and its feet are less elongate, with the

third articulation simple (instead of expanded and bilobed ).

Its capitulum, too, although not particularly abrupt, is

very largely developed; and its eyes, although not pro-

minent, are likewise large.

78. STENOMIMUS (nov. gen.).—The present group is

founded on a very minute, narrow, and pallid little

Brazilian Cossonid, several examples of which were cap-

tured by Mr. Fry near Rio Janeiro; and it may perhaps

be looked upon as the more southern representative, in

South America, of the preceding genus—which occurs

from, at all events, the West Indian islands to the region

of the Amazon. It is indeed very closely allied to Micro-

mimus,—from which it nevertheless differs in its narrower,

and relatively more parallel and elongated, outline; in its

surface being less shining, and (at any rate so far as the

elytra are concerned) minutely and sparingly sericeous ; in

its rostrum being longer, slenderer, and more strictly

parallel; in its antenne being medial as regards their

insertion (instead of ante-medial); in its eyes being more

rounded, and (instead of depressed) extremely prominent;

in its prothorax being more triangular, and more deeply

constricted in front ; in the elytra being proportionately

rather longer and more linear, but at the same time less

acuminated at their extreme apex, where the pygidium is

but barely covered; in its tibie beimg more evidently

armed at their inner angle with a minute spinule; and in

its tarsi being slenderer.

79. Micromimus (nov. gen.).—The two minute and

rather closely allied species for which the present genus is

proposed, are from the collection of Mr. Fry. One of

them is West-Indian, having been taken in Trinidad ; and

the other was captured, apparently by Mr. Bates, in the

region of the Amazon. They are remarkable for their

pallid hue, and shining, deeply sculptured, somewhat

depressed surfaces; for their rostrum being short, broad,

and nearly parallel (it being but very slightly narrowed

posteriorly); for their eyes being transverse and ex-

tremely large, but nevertheless completely sunken or

Genera of the Cossonide. 565

depressed ; for their antennz (which are implanted a little

before the middle of the rostrum) having their scape

greatly abbreviated, but rather unusually (and suddenly)

clavate at its apex; for all their coxe (even the front ones)

being widely, and subequally, separated ; and for the third

joint of their feet being simple. Their rostrum is not

divided from the forehead by a basal line as in Catole-

thrus; and their body, as in that genus, seems to be

perfectly free from pubescence.

80. GL@OTROGUS (nov. gen.).—Although prima facie

on the Cossonus type, the curious insect which I have

made to constitute the type of the present genus, and

which has been communicated by Mr. Pascoe and Mr.

Janson as having been captured by Mr. Wallace in the

islands of Morty and Gilolo of the Malay archipelago, is

one of the most anomalous members of the family with

which I am acquainted,—being conspicuous not only for

its highly-polished, almost unsculptured, and extremely

flattened body (both above and below); but likewise for

its greatly exserted, depressed, elongate-squarish head ; its

large but sunken eyes, which are a good deal approximated

on the under side of the latter; for its exceedingly short

and broad, but nevertheless almost parallel rostrum (which

_ is merely a little contracted at the base); for its antennz

(which are inserted considerably behind the middle of the

latter) having their scape elongate, outwardly curved and

compressed, and greatly clavate anteriorly (where however

it is obliquely lopped-off on the inner side, occasioning

a tolerably well defined angle to be shaped-out at some

distance from the tip), their funiculus much abbreviated,

but with the joints increasing gradually, but very con-

spicuously, in width towards the club—which is exceed-

ingly large, elongate-oval, and densely clothed (as with

velvet); for its prothorax being straightly truncated (or

even, if anything, perhaps, a little scooped-out), instead of

trisinuated, behind, unconstricted in front, and perfectly

even; and for its legs (which are short, especially the

hinder ones) being very widely separated at their base,

with the femora much clavate, and with the tarsi (the

third joint of which is simple) rather slender and filiform.

81. HomaLorroaus (nov. gen.).—The present genus,

together with the one which precedes and the one which

follows it, belong clearly to the same geographical type

566 Mr. T. Vernon Wollaston on the

(or, more strictly, perhaps, to the same cluster of types),—

peculiar, apparently, to the islands of the Malay archi-

pelago; and yet I scarcely think that they could be

regarded as representing even distinct sections of a single

group. At any rate, if I were to treat them now as such,

I feel that the time would assuredly arrive when (as

I have lately done with the forms which cluster around

Mesites) they would be separated; and hence I have

thought it desirable to forestall that event by detaching

them at once.

With this preliminary remark, I may state that Homalo-

trogus differs from Glaotrogus in its type being a little

more evidently (though at the same time very lightly)

sculptured, and not so highly polished ; in its head being

much narrower, more convex, and oval (instead of flattened

and subquadrate); in its eyes being consequently less

widely separated; in its rostrum being much longer and

more convex, and (instead of nearly parallel) with the hinder

half comparatively slender and contracted, and with there-

fore the anterior one suddenly dilated (much as in Cos-

sonus); in its prothorax (which is exceedingly even) being,

if anything, squarer still, though more evidently constricted

at its extreme apex; in the last three segments of its

abdomen being margined behind with a row of large

punctures; in its antennz (which are inserted conspi-

cuously before, instead of behind, the middle of its much

longer rostrum) having their scape straighter and less

outwardly curved, and only obsoletely truncate towards the

inner apex (and therefore with but a very slight tendency

for the anguliform projection which is so marked a feature

in Gleotrogus), and having their second funiculus-joint

appreciably less shortened; and in its legs being longer,

with the femora (at any rate the posterior four) somewhat

less clavate, and with the tibiz less abbreviated. Judging

from the labels which are appended to them, the types

now before me (which are from the collection of Mr.

Pascoe) were taken by Mr. Wallace in the islands of

Coram and Batchian, of the Malay archipelago.

82. IsorroGus (nov. gen.).—This genus makes a nearer

approach to the normal Cossonus pattern than either of

the preceding two; yet it certainly is not identical with

that group,—its extremely flattened body and unimpressed

prothorax, and the peculiar construction of its scape

(which is biflexuose, and shows a more distinct tendency

Genera of the Cossonide. 567

than even the last genus does, for the inner anguliform

projection which is so conspicuous a feature in Gleotrogus),

added to its abbreviated funiculus, its greatly enlarged

capitulum, its elongate, oval, much exserted head, and the

fact of its large but depressed eyes being considerably

approximated on the underside, affiliating it unmistakeably

with the small assemblage of types which appear to be

characteristic of the islands of the Malayan archipelago.

As compared with Homalotrogus, the present genus is

remarkable for the body being both larger and very much

more deeply and coarsely sculptured ; for its rostrum being

more parallel (7.e. much less contracted behind, and there-

fore less expanded in front); for its head being a little

thicker (or less narrowed); for its antenne (which are

more strictly medial as regards their insertion, instead of

ante-medial) having their scape rather more evidently

sinuated internally, and their second funiculus-joint not in

the slightest degree lengthened; and for its prothorax

being longer, or more oblong, and more decidedly tri-

sinuated along its basal edge. The two species from which

my generic diagnosis has been compiled were collected by

Mr. Wallace in the island of Batchian.

83. HETEROPHASIS. (nov. gen.).—The very beautiful

insect, so remarkable for its rufescent prothorax, and the

other, totally dark one, on which the present genus is

established, are from the collection of Mr. Pascoe, and

were captured by Mr. Wallace at Dorey in New Guinea.

In the more ordinary construction of their rostrum and

antenne they make a still nearer approach to Cossonus

than the members of any of the three preceding groups.

Nevertheless I think they may fairly be separated from

the true Cossoni,—from which they may be said to differ

not only in their surface being at times more elegantly

coloured (a fact of great significance in this department of

the Rhyncophora), but likewise (which is equally im-

portant) in their more fusiform, or less parallel, outline,

their extremely depressed surface (in which respect they

agree with the three preceding genera), their rather more

prominent eyes, and in their prothorax (which is alike

free from a keel and a depression) being almost totally

unsculptured—with the exception of being impressed down

either side of its central region (and in the anterior con-

striction) with a row of punctures—which in H. rujicollis

are extremely large, but almost obsolete in the concolor.

568 Mr. T. Vernon Wollaston on the

The first and second segments, also, of their abdomen are

more completely fused into each other than is the case

with any of the Cossoni which I have hitherto examined.

Although rather more parallel in outline, I believe that

the Cossonus glabricollis, Bohm., from southern Africa,

will enter into this genus.

84. Cossonus (Clairville, Ent. Helv. i. 58. 1798).—

The genus Cossonus, so widely distributed over the world,

presents a great amount of structural instability as regards

the degree of rounded-dilatation towards the apex of its

rostrum and the coarseness of its sculpture; and I think it

far from unlikely that a close comparison of its numerous

representatives (as at present acknowledged) might enable

us to separate them into two or three tolerably distinct

groups; nevertheless as it is not my object in this memoir

to monograph the closely-allied species of genera which are,

on the whole, sufficiently well understood, I shall not

attempt to do more than detach a few forms which are

readily accessible to me, and concerning the claims of

which for separation there can, I think, be no reasonable

doubt. Amongst, however, its multitude of specific modi-

fications, Cossonus is by no means unsatisfactorily defined,

—the more or less narrow, parallel, depressed, deeply-

sculptured, dark, and shining bodies of the insects of which

it is composed, in conjunction with the form of their ros-

trum (which is always contracted behind, though often

very shortly so, and spatulate, or expanded in front,—

sometimes to an extraordinary, and at others to merely a

slight, extent), its more or less longitudinally-impressed

prothorax, rather widely separated anterior cox, and the

unexpanded third joint of its feet, giving it a character

which it is impossible to mistake. Its antennz are inserted

into the roundly-expanded apical portion of its rostrum ;

its eyes are transverse, oval, and not very widely separated

across the forehead; and its surface is nearly always free

from every trace of pubescence.

85. Hyponotus (nov. gen.).—I am indebted to Mr.

Pascoe for the loan of the curious insect for which the

present genus has been erected ; and, judging from a label

which is appended to it, it appears to have been captured

by Mr. Wallace at Singapore, in the Malay peninsula.

Its elongated, parallel outline, and dark, opake, closely

sculptured surface, give it somewhat the appearance at

renera of the Cossonide. 569

first sight of a minute Tenebrio ; and although it is mani-

festly much allied to Cossonus, I feel satisfied that it can-

not be admitted amongst the numerous specific modifi-

cations of that extensive group. ‘Thus, not only is its

opake upper-surface sparingly besprinkled with very short

and minute fulvescent sete: (a circumstance of great signi-

ficance in this particular department of the present family ),

but its head is considerably broader and more developed,

with the eyes (which are rounder and more prominent)

consequently much more remotely separated ; its rostrum

likewise is wider, shorter, and more parallel (it being

merely a trifle narrowed, and gradually so, behind), its

prothorax (which is relatively more abbreviated and more

oval) is’ very coarsely, densely, and uniformly punctured

all over, but unimpressed (although sub-carinulated) pos-

teriorily, and its legs (the intermediate ones of which are

extremely wide apart) have their femora (the four hinder

ones of which are less clavate), their tibiz (which are

slightly flexuose), and their tarsi, each of them, propor-

tionately, more elongated.

86. BoropHLa@us (nov. gen.).—The members of the

present genus, which appear to be North-American (one

of them having been communicated by Mr. Fry as coming

from Mexico, and the other by Mr. Janson), are, I sus-

pect, in most collections treated as small Cossonz ; never-

theless it seems to me to be scarcely possible to refer them

to Cossonus, as rigidly defined,—from which they differ,

not only in their rostrum being relatively shorter, broader,

and nearly parallel (indeed completely so as regards one

of the species), but also in their eyes being larger, rounder,

more prominent, and more widely separated, in their pro-

thorax being more egually and closely (though very

coarsely) punctured, and unimpressed behind, in their

metasternum being longer, their coxze more approximate,

and the third joint of their feet less decidedly simple (it

being, although very minutely so, sub-bilobed).

87. PACHYTROGUS (nov. gen.).—The affinities of this

genus, which is founded on an insect from Chili com-

municated by Mr. Janson, are extremely difficult ; for

whilst the large size and robust general aspect of its type,

in conjunction with its somewhat shortened scape, is at

first sight entirely suggestive of Stereoborus and Stereo-

tribus, its still thicker and broader rostrum (the tendency

570 Mr. T. Vernon Wollaston on the

of which is rather to be subtriangular, than posteriorly

narrowed), and its depressed, less widely separated eyes,

added to its very grossly and equally punctured prothorax

(which is free from a constriction in front, and is nearly

unsinuated at the base), and its convex body, are far more

in accordance with what obtains in such sub-Hylastideous

eroupsas Brachytemnus. On the whole, however, | think

it will be more natural to retain it in the vicinity of the

former,—and more especially since their is no appearance

of the excessive reduction in the length of the scape which

is so characteristic of the latter; nor yet of the obtusely-

desilient apical region of the elytra, the subcontiguous

anterior cox, and the slender feet, of those particular

types. Its tibiz are not so abbreviated as in Stereoborus

and Stereotribus, and the front pair seem to be simple (or

un-augmented internally ; its scutellum is largely deve-

loped; and its rostrum, although unprovided with any

anomalous tubercles and channel-like fissures, 1s never-

theless obsoletely gibbose, or uneven, on its upper surface.

88. STEREOBORUS (nov. gen.).— The insects which

I would include under the present genus and the follow-

ing one, although apparently (for the most part) unde-

scribed, are some of them (on account, doubtless, of their

rather large size, and dark, shining, deeply-sculptured

surfaces) mixed-up in collections with the Cossoni—from

which, however, they are, nevertheless, totally distinct.

Indeed in the construction of their extremely robust and

thickened legs they are very peculiar,—the femora (though

especially the anterior ones) being greatly incrassated,

whilst the tibize are unusually short, broad, and somewhat

compressed, with the terminal hook powerfully developed ;

the front pair moreover being abnormally augmented on

their inner edge (at some distance behind the internal

angle) by a kind of lamelliform triangular plate (which

however only becomes conspicuous when the insect is

viewed obliquely). In other respects Stereoborus recedes

from Cossonus in its head being considerably larger and

broader ; in its eyes (which are rounder and more promi-

nent) being consequently much wider apart ; in its rostrum

(which is furnished with a narrow, anteriorly-evanescent

channel in the centre, arising out of a minute frontal

fovea) being conspicuously shorter, broader, and more

parallel (in fact nearly guadrate); in its prothorax being

longer, and somewhat more cylindrical; and in its cox

Genera of the Cossonide. 571

(though particularly the front ones) being more approxi-

mate. Its antennz (which are implanted before the middle

of the rostrum) are rather thick, with their scape slightly

abbreviated, and their funiculus (the second joint of which

is but very little longer than those which follow it) to-

lerably compact,—though not so compact as in Stereo-

tribus.

The genus seems to be peculiar (so far as I am aware)

to the islands of the Malayan archipelago,—the specimens

now before me (from the collections of Mr. Fry and

Mr. Pascoe) having been captured by Mr. Wallace at

Dorey in New Guinea, and in the islands of Gilolo and

Matabello.

89. STEREOTRIBUS (nov. gen.).—The members of the

present group are very closely allied, in external aspect

and general structure, to those of the preceding one,—

from which they seem mainly to differ in their head being

a little less widened, and their rostrum (which in the

S. incisus and tuberculifrons, from Ceylon, is rather

longer, and distinctly narrowed towards the base) being

not only furnished behind with a very deep, short, wide,

and somewhat gaping slit, or (as it were) gash (often ac-

companied by posterior frontal tubercles and inequalities),

which takes the place of the narrow channel in Stereoborus,

but likewise more or less bearded beneath, at the apex,

with elongated hairs. Their eyes, too, are a little more

prominent; their funiculus (the second joint of which is

not at all longer than those which follow it) is more solid,

or compact; and the additional lamelliform process which

augments the inner edge of the two front tibize is armed at

its base with a very conspicuous and robust spine (which

is best seen when the insect is viewed obliquely and from

behind). Like that genus, it is widely spread over the

islands of the Malayan archipelago,—examples, obtained

by Mr. Wallace in Batchian and Tondano, having been

communicated to me by Mr. Pascoe; and it appears to

range eastward, in however a slightly modified form (as

witnessed by its somewhat longer and more posteriorly-

narrowed rostrum, and its more developed club), to at all

events Ceylon—from whence several individuals (repre-

senting my S. incisus and tuberculifrons) are now before

me from the collection of Mr. Fry.

I have thought it desirable to append a subgeneric title

TRANS. ENT. SOC. 1873.—PART IV. (OCT.) Ss

572 Mr. T. Vernon Wollaston on the

to the two species from Ceylon, in the event of its being

found desirable ultimately to detach them from the others ;

though I scarcely imagine that their slight structural

peculiarities of rostrum and club are of sufficient _import-

ance to indicate more than perhaps a geographical modifi-

cation of a rather plastic type.

90. STEREOMIMETES (nov. gen.). — The rather large

Cossonid which constitutes the type of the present genus,

and which Mr. Pascoe has communicated as coming from

Champion Bay in Western Australia, is manifestly akin

to Stereoborus and Stereotribus, though at the same time

approaching in the outline, colour, and sculpture of its

oblong prothorax, as well as in the bipartite structure of

the spine which arises from the inner angle of its four

posterior tibie, the genus Phaeegaster. However it

entirely wants the short conical feet and the peculiarly

formed rostrum of the latter, and of the groups which are

allied to it; and its affinities appear to me to be clearly

with Stereotribus,—with the aberrant members of which,

from Ceylon, it very much agrees in (amongst other

details) the shape of its robust, posteriorly - narrowed

rostrum.

Despite however the undoubted relationship of this

genus to Stereotribus, not only does the form of its almost

basally-unsinuated prothorax and elytra and the structure

of its inner tibial spur shew it to be unmistakeably distinct ;

but its antennze (which are implanted further from the

apex of the rostrum) are considerably thicker and differently

constituted,—their scape being eatremely robust, sub-tor-

tuous, and powerfully clubbed, their funiculus remarkably

broad, but with the joints nevertheless (instead of being

compact) sharply and deeply separated from each other,

and their capitulum small and narrow (as in the Rhyncol).

Its rostrum, which is a good deal rounded-outwards ante-

riorly, has a wide channel behind (which arises from a

large frontal fovea); its eyes (as in the neighbouring

groups) are very prominent; its prothorax is much less

coarsely punctured, and its elytra are more strictly parallel,

than is the case in Stereotribus and Stereoborus ; its legs

are longer, and not quite so broad,—both of which points

are particularly observable as regards the tibiz; and the

front pair of the latter are less decidedly augmented in-

ternally by a lamelliform portion towards their base. Its

colour, too, is less intensely black,—the anterior segments

Genera of the Cossonide. 573

and the underside being (at any rate in the example now

before me) piceous, with the limbs of a still clearer tint.

91. STEREODERUS (nov. gen.).—The present genus is

manifestly allied to Stereoborus and Stereotribus,—though

the rather smaller size to which its members would appear

to descend, added to their more convex, cylindrical bodies,

more lightly sculptured surface, and their more conical,

unimpressed prothorax, gives them more the appearance

at first sight of such forms as Xestoderma and Xestosoma

(which are equally dark and highly-polished, and have a

broad, abbreviated rostrum) in the vicinity of the Rhyncoli.

Nevertheless, the peculiar construction of its rostrum,

which is often barbed beneath with long fulvescent hairs,

and has three small clefts in the upper anterior excavation

which receives the labrum, as well as a curious tendency to

be armed with one or more tubercles in the centre behind

(all of which exist, more or less modified, in Stereotribus),

is too significant to be misunderstood. And when we add

to this the characteristic shortness of its scape, the exces-

sive robustness of its limbs, and the internally dilated

basal half of its anterior tibiz (the superadded triangular

portion arising from a robust spinule, situated at some

distance behind the spiniform inner angle), each of which

is conspicuously expressed in that genus, there can be no

longer the slightest room for doubt as to its true affinities.

Its eyes are large, very wide apart, and somewhat anterior

in their position ; and its third tarsal joint, as in most of

these immediate groups, is simple.

Stereoderus is a genus which would seem to have a

rather extended geographical range,—out of the three

species now before me (all of which are from the collection

of Mr. Pascoe), two having been captured by Mr. Wallace

in the islands of the Malayan archipelago, whilst the other

is from the Fiji islands in the Pacific. The latter, how-

ever, although I think it is impossible to regard it as

generically distinct, shows a slight structural difference in

the minute emargination at the extreme apex of its

rostrum,—the large medially-cleft lobe, which nearly fills

up the cavity in the other two species (causing the whole

central piece to appear trifid) being so short, small, and

entire as to be strictly obsolete. But so diminutive a

character, even though structural, can scarcely be regarded

as more than a trivial one.

574 Mr. T. Vernon Wollaston on the

92. OxYDEMA (nov. gen.).— The present genus is estab-

lished to embrace three large and very closely allied

species,—two of which (taken by Mr. Wallace in the

islands of the Malayan archipelago) are from the collec-

tion of Mr. Pascoe, and the other (from Ceylon) in that

of Mr. Janson. They are at once conspicuous for their

elongate, narrow, and fusiform outline being a good deal

attenuated both before and behind (particularly the latter),

their dark hue, and their somewhat slender, considerably

lengthened rostrum,—which however is not quite parallel,

being appreciably broader in its anterior half (in front of

the antenne) than it is posteriorly. Their eyes are

rounded and prominent, their prothorax is even and much_

constricted in front, their elytra are gradually narrowed

from the base to the apex (where they have a tendency to

be separately and minutely rounded-off), their anterior

coxze are very remote, and their antennz and legs (the

latter of which have the third tarsal joint bilobed) are

rather long.

93. Noriosomus (nov. gen.).—Three insects now before

me—two of which have been communicated by Mr. Pascoe

as coming from western Australia, whilst the other (bear-

ing the label ‘“* New Holland”) is from the collection of

Mr. Fry,—although, I think, specifically distinct, belong

unquestionably to the same genus, and that genus is

certainly not far removed from Oxydema. Nevertheless

I feel satisfied that they cannot be actually associated with

the members of the latter, which moreover appear to have

a more tropical range,—occurring in (at any rate) the

Malayan archipelago and Ceylon; and I would therefore

regard them as pertaining to an Australian type, which

perhaps may have other representatives in its own particu-

lar province.

Prima facie, however, the present genus has much in

common with Oxydema,—with which it agrees in its

rather large size, and in the fact of its rostrum being a

little reduced in width behind the insertion of the antenne;

nevertheless it recedes from the exponents of that group

in the body being altogether (proportionately) less nar-

“rowed, and much less attenuated posteriorly, as well as

less shining and sometimes less black; in its rostrum

being rather shorter, and not quite so distinctly contracted

along its basal half; in its antenne (which are somewhat

thinner) having the second funiculus-joint less decidedly

Genera of the Cossonide. 575

abbreviated, and the club less developed; in its prothorax

being generally more conspicuously narrower than the

elytra, less elongate, and not so deeply constricted in

front ; in its scutellum being less transverse; in its meta-

sternum being appreciably shorter; and in its feet being

slenderer, with their third articulation usually smaller and

narrower, and much more minutely bilobed. Its eyes, as

in Oxydema, are extremely prominent, and its sculpture is

rather coarse. The first of the three species, however,

which are described in this paper (—namely the O. major),

I may add, is not quite so typical of the group as the other

two; nevertheless I do not think it can be looked upon as

an Oxydema.

94, APHANOCORYNES (nov. gen.)—In its rather large

size, elongate, narrow, subfusiform outline, and deep-black

hue the insect for which the present genus is founded, and

which has been communicated by Mr. Pascoe (as having

been captured by Dr. Masters at King George’s Sound,

in southern Australia), has somewhat the appearance at

first sight of Oxydema—which occurs in Ceylon and the

islands of the Malayan archipelago. Nevertheless it

differs in its body being more depressed, and much more

finely and closely sculptured, in its elytra being less at-

tenuated posteriorly, and without any tendency to be sepa-

rately rounded-off at their extreme apex, in its rostrum

being a litle shorter and entirely parallel, and in its club

being very much less developed. Indeed this latter is even

smaller, narrower, and more acuminated than in even the

typical Rhyncoli. Its prothorax too (which however, as

in that genus, is deeply constricted at the apex) is not

altogether even,—it being widely, but lightly, impressed

in the centre behind; and its third tarsal joint is more

evidently dilated and bilobed, and the terminal one is

shorter, than is the case in Oxydema.

95. ORTHOTEMNUS (nov. gen.).—As in the two pre-

ceding genera, the type of the present group (which ap-

pears to be extensively spread over the islands of the

Malayan archipelago) is a comparatively large and elon-

gate insect, and of a dark hue; but it recedes in many

important particulars from the neighbouring forms,—par-

ticularly however in its flattened surface, and elongate,

triangular prothorax, which is very straightly truncated at

the base (where it is of the same width as the elytra—

576 Mr. T. Vernon Wollaston on the

which are perfectly parallel, and are likewise very straightly

truncated in front), and in its rostrum being rather long

and robust, but of equal breadth throughout, in its eyes

being very largely developed, in its elytra being separately

recurved at their extreme apex, in its third tarsal joint

being small and almost simple, and in its four anterior

cox being very widely and subequally distant, whilst the

posterior ones are, if anything, even less remote than the

others,—a character which is most unusual amongst the

Cossonids. The examples now before me (all of which

seem to pertain to a single species) are from the collection

of Mr. Pascoe,-and were captured by Mr. Wallace at

Dorey in New Guinea, as well as in Batchian, Makian,

and Ceram.

96. Macroruyncouus (Wollaston, Trans. Ent. Soe.

Lond. 33. 1873).—The present genus, which I estab-

lished a short time ago to receive a Cossonid which was

obtained by Mr. G. Lewis in Japan, and of which a

second species (from Ceylon) is now before me, communi-

cated by Mr. Fry, is somewhat intermediate between the

preceding groups and Rhyncolus ; nevertheless I believe

that it is, in reality, far more nearly allied to the former

than to the latter. From Rhyncolus it differs, principally,

in the body being relatively longer, narrower, and more

parallel,—it being less convex, and without any tendency

to be ovate (or expanded behind the middle); and its

surface is more shining, and of an intenser black. Its

rostrum is more strictly parallel,—being indeed, if any-

thing, rather contracted, perhaps, than otherwise, towards

the base (instead of, as in the Rhyncoli, somewhat thick-

ened); its eyes are larger and more prominent; its pro-

thorax and metasternum are more elongated; its club

(although small) is both less narrowed and less acuminate ;

and its four anterior coxe are a little more remote.

97. Heterartuus (Wollaston, TZrans. Ent. Soc.

Lond. 29. 1873).—It was for two very closely related

species which were captured by Mr. G. Lewis in Japan

that I lately established the genus Heterarthrus ; and a

third is now before me, from the collections of Mr. Pascoe

and Mr. Janson, from the same region,—it having been

taken near Nagasaki, in the island of Kushiu. They

may be known from the members of the neighbouring

groups by their convex and fusiform bodies having the

Genera of the Cossonide. 577

elytra either altogether pale, or else (which would seem

to be the normal condition) ornamented with suffused

blackish markings. The head is narrow, with the eyes

consequently less wide apart than what is the case in most

of these immediately-allied types; and the rostrum is

somewhat short and robust, though by no means very

broad, and gently, but appreciably, dilated towards the

tip—which is, itself, rather stratghtly truncate. The

prothorax (which is finely and densely punctulated) is a

good deal narrowed, and much constricted, in front; and

the antennz and legs (the former of which have their club

shortish, and tolerably abrupt) are comparatively slender.

The intermediate coxe are remotely separated (occasion-

ing the four hinder ones to be equidistant) ; the femora

are unusually thin towards their base ; and the tarsi (which

have the terminal joint ordinary and clavate in the males,

but subconical in the females) are very conspicuously

lengthened.

98. CONARTHRUS (nov. gen.).—In the conical but not

abbreviated last joint of its feet (which may, or may not,

be indicated in both sexes,—for I have only a single ex-

ample of each species from which to judge), no less than

in the densely punctured anterior portion of its surface,

and its short, unacuminated club, the present genus

(which is founded on two species whieh were captured by

Mr. Wallace in the islands of the Malayan archipelago,

and a third, from Cochin China, which has been com-

municated by Mr. Fry) is more related, I think, to

Heterarthrus and Eutornus than it is to the groups

around Hzonotus and Phacegaster—with the latter of

which, nevertheless, in the proportions»of its broad head

and rostrum, as well as its large size and parallel, cylindric

body, it almost entirely agrees. It may be known from

the forms amongst which it seems to me most natural to

associate it by its elongate, linear outline, black hue, sloping

(or sub-perpendicular ) scutellum (—a character, however,

which is less distinctly indicated in the C. vicinus from

Cochin China), its exceedingly flexuose anterior tibiz,

and its wide head and rostrum,—the former of which is

also much exserted, whilst the latter varies in the two

Malayan examples now before (but which I nevertheless

believe are both of them females), being in one instance

perfectly parallel, and in the other not only a little longer

but appreciably dilated anteriorly. It is possible however

that I may be mistaken in regarding these two Malayan

578 Mr. T. Vernon Wollaston on the

individuals as pertaining to the same sex, in which case

the outline of the rostrum may perhaps be only sexual.

But, be this as it may, I suspect that they are specifically

distinct from each other.

99. EuTorNus (nov. gen.).—The two insects which I

have described as members of the present genus are from

Ceylon and the Malayan archipelago,—the one from the

former having been communicated by Mr. Janson (to

whom I have dedicated the species), whilst the other is

‘from the collection of Mr. Pascoe and was captured by

Mr. Wallace.* Indeed, judging from the many examples

now before me, the Malay an representative would appear

to be widely spread over those particular islands, and also

to be remarkably constant, or free from variation,—the

types of it which I have examined having been obtained

in New Guinea, Morty, Tondano, Gilolo, and Makian.

The characters of the genus are very similar to those

of Conarthrus, and yet I feel satisfied that the two groups

are essentially distinct, — Eutornus receding from the latter

not only in the less parallel (or more fusiform) outline,

and more lightly sculptured surface, of the insects for which

it is established, and in the peculiarity of their colour,

which (instead of a uniform black) is rufo-ferruginous,

with the anterior and posterior portions more or less suf-

fused, or obscured; but likewise in their rostrum being

apparently always linear, in their prothorax being less

straightly truncated (or more subsinuated) at its base, in

their scutellum not being tilted (or sub-perpendicular), in

their elytra being (as in Heterarthrus) obscurely, and

minutely, rounded-off, separately, at the extreme apex,

and in the last joint of their feet being less conspicuously

conical. Their first and second abdominal segments, too,

are more convex,—having scarcely any tendency to be

longitudinally hollowed-out, or concave.

100. Corrus (nov. gen.).—The two curious and closely-

allied little species on which the present genus is estab-

lished have been communicated by Mr. Pascoe, and were

taken by Mr. Wallace in the islands of New Guinea and

Sula, of the Malayan archipelago. Apart from their

rather small size, parallel outline, subdepressed surface, and

their rufo-piceous, or piceo-ferruginous hue, they may be

be found eventually to pertain to a new ‘but cognate genus,

known readily from the neighbouring forms by their eyes

being enormously developed and very prominent, by their

antennze (which have the second funiculus-joint much ab-

breviated, and the club abrupt) being inserted towards the

base of their rostrum, and by the latter being exceedingly

broad (indeed scarcely narrower than the head), but never-

theless parallel, much arcuated, and straightly truncate,

or lopped-off, in front. The third articulation of their

feet is simple, and their coxze (even _ anterior pair) are

widely and subequally separated.

101. Pacnyors (nov. gen.).—Two examples of the

species for which the present genus has been established

(which have been communicated by Mr. Pascoe), were

obtained by Mr. Wallace at Sarawak in Borneo. They

may be known from the allied forms by their narrow,

parallel, cylindric, and rather deeply, closely sculptured

bodies; by their broad, thick, convex, greatly exserted

head; by their short and wide rostrum; by their long,

subconical prothorax, which is but lightly constricted in

front; by their elongate scape, and roundish, abrupt, com-

pressed, largely-developed club; and by their coxz being

somewhat less separated than is the case in the neigh-

bouring groups,—the anterior pair being scarcely, if at all,

more remote than in the Rhyncoli.

102. PENTAMIMUS (nov. gen.).—Several examples of

a Cossonid which I have received from Mr. Pascoe as

coming from King George’s Sound in southern Australia,

and a closely allied species (likewise Australian) which

has been communicated by Mr. Fry, have so much the

prima facie aspect of large Rhyncoli that they might be

almost supposed to pertain to that genus. Yet their

5-jointed funiculus, and rounder and more developed club,

show them to be altogether distinct ; though their affinities

are so unmistakeably with the Rhyncoliform groups that

it would be absurd to suppose (on account of the structure

of their funiculus) that they have anything whatever to do

with the subfamily Pentarthrides. In other respects Pen-

tamimus is remarkable for its shining, deeply sculptured

and cylindrical body; for its thickened head, and short,

broad (though parallel) rostrum ; for its somewhat incras-

sated antennz (which are implanted a-little behind the

middle of the latter) having their scape a good deal

lengthened and backwardly curved; and for its legs being

rather long and thick, with the third tarsal joint simple.

103. TETRACOPTUS (nov. gen. ).—The present genus, the

type of which (although very much smaller, and more

lightly punctured) at first sight closely resembles Penta-

mimus, 18s remarkable for its guadriarticulate funiculus,—

it being the only instance amongst the entire Cossonide,

outside the subfamily Dryophthorides, so far at least as I

have hitherto observed, in which that organ is composed

of but four joints; yet so unmistakeably is it a member,

as regards the whole of its other details, of the Rhyncoli-

form : groups that it would be as absurd to remove it on

account of the structure of its funiculus into the Dryoph-

thorides (with which in everything else it totally disagrees)

as it would be to regard Pentamimus and Tomolips as

Pentarthrids, or to include Hezrarthrum amongst the

Onycholipides. In point of fact there can be no question,

despite its 4-jointed funiculus, about its affinities ; and it is

a significant fact that the only exponents of the subfamily

Cossonides in which the funiculus is made-up (so far as I

am aware) of less than seven articulations should pertain

to genera which appear, in a natural system of arrange-

ment, to be at no great distance from each other,—namely

Hexarthrum (in which the funiculus is composed of six

joints), Zomolips and Pentamimus (in which there are

but five), and Tetracoptus (where the number is reduced

to four).

Apart however from the primary peculiarity to which I

have just called attention, T'etracoptus may be known by

its cylindrical body and very lightly sculptured surface ;

by its exceedingly short and broad, but nevertheless pa-

rallel, rostrum (w hich has a wide, but shallow, channel in

front) ; ; by its elongate, large, subconical prothorax (which

is about the same width posteriorly as the elytra, and is more

constricted in front than in Pentamimus); by the small-

ness of its scutellum; and by its abrupt, considerably-

developed club. Its anterior coxe are tolerably wide

apart, and the four hinder ones are about equidistant; its

legs (especially as regards the tibiz) are somewhat short,

its third tarsal joint is simple, and its claws are minute.

The single example of this genus from which my diag-

nosis is compiled has been communicated by Mr. Pascoe,

and was captured by Mr. Wallace at Dorey in New

Guinea.

and appear to be extensively spread over the Malayan

archipelago—whence two species of each, now before

me (which have been communicated by Mr. Pascoe),

were obtained by Mr. Wallace in the islands of Ceram,

Morty, Batchian, and Ternate. They belong to a type

quite distinct from any of the preceding ones,—their very

lightly sculptured, shining, deep-back, cylindrical bodies,

in conjunction with their short, broad, and thick rostra

(which are but very little narrower than the head), their

excurved scape, their abrupt, compressed club, and the

fact of their first and second abdominal segments being

divided by a very conspicuous line, giving “them a cha

racter which it is impossible to mistake. In Xestoderma

the rostrum is free from an anterior channel, the capitulum

is but moderately developed, the intermediate cox are

very remotely separated, and the third tarsal joint is quite

simple. The scutellum is either small and somewhat

rounded, or else smaller still, short and transverse.

105. XESTOSOMA (nov. gen.).— As already implied, the

members of this genus have much the appearance of those

of the preceding one; nevertheless the body is relatively

a little broader and thicker; and moreover, whilst one of

the species is highly polished, the other is almost opake.

The antennz too have their scape longer and somewhat

more robust, and their club dark and sericeous, and con-

siderably more developed,—it being very large and rounded

in the X. grandicollis, but oval in the subopacus. The

scutellum is very minute, short, and transverse (rather

more so perhaps than in even the Xestoderma atra); the

intermediate cox are rather less widely separated; and

the third tarsal joint is not quite simple,—it being appre-

ciably (at any rate in the anterior pair), though very mi-

nutely, sub-bilobed, or cordate.

106. Lissopsis (nov. gen.).—Unfortunately the only

example which is accessible to me in drawing out the

characters of the present genus has lost its antenne; yet

its other details are so well defined, and I am so convineed

that the insect cannot be referred to any other group enun-

ciated in this paper, that I have no hesitation in treating

it as a distinct type of the sub-Hylastideous Cossonids with

exceedingly abbreviated rostra. It is at once remarkable

for its rather wide, short, and parallel-oblong outline (which

is somewhat obtuse both before and behind) ; for its ros-

582 Mr. T. Vernon Wollaston on the

trum, although thus abbreviated, being nevertheless sub-

parallel, rather than triangular, as well as slightly concave

in the middle, and most curiously polished (and unsculp-

tured) at the base ; for its eyes being, as in Spherocorynes,

extremely prominent; for its prothorax being large and-

convex, about equally rounded at the sides, and of the

same breadth at its widest part as the elytra; for the

latter being shortly-cylindric, very deeply and coarsely

sulcate-punctate, and obtusely rounded and minutely

asperated posteriorly ; for its tibize (at any rate the front

pair) being subflexuose; and for its coxe, even the an-

terior ones, being widely separated. ‘The specimen which

has furnished the diagnosis is from the collection of Mr.

Pascoe, and was captured by Mr. Wallace at Saylee on

the north-west coast of New Guinea.

107. SpH#ROCORYNES (Wollaston, Trans. Ent. Soc.

Lond. 38. 1873).—Spherocorynes is one of the many

genera the discovery of which is due to the researches of

Mr. G. Lewis in Japan; and it is conspicuous for its

very short and channelled rostrum being nevertheless (as

in Lissopsis) parallel, rather than triangular, and for its

antenn (which are thickened and considerably developed)

having their scape elongate, their funiculus abbreviated,

and their club large, rounded, and abrupt. Its eyes are

extremely prominent; its body (which is subcylindrical,

and comparatively lightly and delicately, though rather

closely, sculptured) is convex, just appreciably sericeous on

the elytra, and rather more evidently so beneath ; and its

legs are subequally separated at their base,—the ante-

rior pair being a little more, and the hinder pair a little

less, remote than is usual amongst the Cossonids. Its

tibiz (the front ones of which are slightly flexuose) are

rather long; and its tarsi have their first jomt considerably

lengthened, and the third one, although scarcely widened,

very minutely (but evidently) bilobed.

108. XENOTRUPIS (nov. gen.).—The affinities of this

genus are somewhat difficult,—its longer and less thickened

rostrum, which is gradually narrowed posteriorly, its less

incrassated head, and fusiform (instead of parallel) out-

line tending to remove it from these immediate groups;

yet at the same time it has so much in common with

them in its convex, shining, deep-black, lightly sculptured

surface, its abrupt and compressed club, its largely de-

veloped prothorax and elongate feet, as also in the fact

of its first and second abdominal segments being divided

from each other by a conspicuous line, that [think it will

be more natural to place it in the present position than else-

where. Its coxe are all of them very widely separated,

though each successive pair is more remote than the one

which precedes it; its eyes are exceedingly large and

prominent; and its prothorax is slightly concave on the

underside. The single species on which the genus is

established is from the Malayan archipelago,—it having

been captured by Mr. Wallace in the island of Batchian,

as well as at Dorey in New Guinea.

109. PACHYSTYLUS (nov. gen.).—Two examples of the

remarkable species for which the present genus is estab-

lished have been communicated by Mr. Fry as having been

received from Chili; and their position in a natural system

of arrangement is not altogether very apparent,—though,

on the whole, I believe that it will be best to place them at

no great distance from Rhyncolus. Nevertheless I must

admit that in the minuteness of their scutellum they stand °

perfectly alone amongst those immediate groups, and make

a far nearer approach to Phleophagus and Caulotrupis.

Still, the scutellum is not quite obsolete; and the other

details of their structure (particularly as regards their in-

crassated limbs, and their short first tarsal and second

funiculus joints) are so much more in accordance with the

corresponding ones of the Rhyncoli that I cannot persuade

myself to remove the genus into the Phlw@ophagus neigh-

bourhood ; though, at the same time, I am far from think-

ing that the situation which I have selected for it is quite

satisfactory. Be the position, however, of Pachystylus

what it may, it is, as a genus, very distinct from every-

thing else with which [am acquainted,—the smallness of its

scutellum and its extremely prominent eyes (which in the

male sex are abruptly terminated posteriorly, but gradually

sloped-off in front), in conjunction with its somewhat

lengthened rostrum (as compared with that of the Rhyn-

coli), which is very much broader in the males than in

the females, and its elongate, thickened scape (which, on

account of its robustness throughout, is but little clavated

towards the apex), giving it a character which is essen-

tially its own. Although not wider than the elytra, its

prothorax (which is almost free from an anterior constric-

tion) is very largely developed, and elongate; and there

is a peculiarity about its surface,—which is subopake

throughout the anterior half, whilst the elytra are slightly

shining, and just appreciably even subzenescent (calling

faintly to mind certain of the Madeiran Caulotrupides).

The underside, too, is rather singularly modified according

to the sex,—the metasternum in the females being a little

concave posteriorly, and furnished in the middle with a

minute, isolated keel, abruptly terminated in front ; whilst

in the opposite sex the keel is absent, but the concavity is

on. (extending through the first segment of the abdo-

men).

110. XENOMIMETES (Wollaston, Trans. Ent. Soe.

Lond. 35. 1873).—Xenomimetes is a genus which was

detected by Mr. G. Lewis in Japan,—where indeed the

only representative of it which I have hitherto seen would

appear to be locally abundant, and (unless I am much

mistaken) of pine-infesting habits. In this latter respect

it consequently resembles H’remotes and Brachytemnus,

with the former of which it has several points (though

perhaps only superficial ones) in common. It may easily

be recognized by its type being elongate, narrow, and

parallel, as well as somewhat opake and very densely

sculptured,—it being also (when viewed beneath a high

magnifying power) minutely pubescent, and asperated,

towards the hinder apex (where the elytra are separately,

and conspicuously, rounded-off, causing them to appear

almost divaricate). The rostrum is rather peculiar m its

construction,—being very short, but nevertheless quite

parallel, and suddenly much narrower than the head; the

eyes are extremely prominent; the club (unlike that of

Evremotes and of the Rhyncolt) is rounded and abrupt, the

antenne being comparatively slender ; the legs (particularly

as regards the tarsi) are a good deal elongated ; the tibize

(more especially however the anterior pair) are elongated

and subflexuose; and the cox are but slightly separated,—

the front ones indeed being not more so than in Rhyncolus,

whilst the two hinder pairs (which are about equidistant)

are by no means very remote.

regarded as an offshoot of Rhyncolus, was established by

myself in 1861 to receive the “ Hylastes crassicornis” of

Brullé,—a Hylastes-shaped Cossonid which infests the

pine-trees of the Canarian archipelago ; and a recent exami-

nation of some of the discordant species of (so-called) Rhyn-

colus has convinced me that the Kuropean R. strangulatus is

an undoubted member of the same group. Indeed a single

example is now before me (described in the after-part of

this paper) which is unquestionably a third representative

of Eremotes, but I have unfortunately no information con-

cerning its precise habitat. However I believe it to be

European,—it having been purchased by John Gray, Esq.

(an whose collection it now is), some years ago, from M.

Tarnier of Dijon, as the ‘* R. chloropus”—with which, I

need hardly add, it has scarcely anything in common.

Judging therefore from the three members which have

hitherto been brought to light, Kremotes may be said to

differ from Rhyncolus in its species being not only larger,

- more cylindrical, and more coarsely sculptured, but like-

wise. in their prothorax being longer, more cylindrical,

and more constricted in front, in its rostrum being shorter,

broader and thicker, in its eyés being more prominent,

and (above all) in the structure of its antenne,—which

are extremely incrassated, their funiculus especially being

thick and robust, and with the second joint so reduced in

length as to be almost hidden within the apex of the greatly

enlarged basal one. In all probability Hremotes will be

found to be exclusively of pine-infesting habits; and it is

far from impossible that the species which I have enun-

ciated in the latter portion of this memoir, under the name

of E. gravidicornis, may prove to have come from the

region of the Pyrenees.

112. Ruyncouus (Germar, Ins. Spec. Nov. 307. 1824).

—Like Phleophagus and Cossonus, the genus Rhyncolus

has had many forms assigned to it, by various authors,

which will be seen, when carefully examined, to be not

strictly on the pattern of its acknowledged type—namely,

the European &. ater, Linn. (or chloropus, Fab.). Thus,

after removing Hremotes (for the reception of the R. stran-

gulatus, Perris), Stereocorynes (for the truncorum, Germ. ),

of possible confusion. Since however the Munich Catalogue, and others,

have not accepted this alteration on my part, which would appear to be

deemed by them to have been unnecessary, I have thought it better to

revert to the original nomenclature.

586 Mr. T. Vernon Wollaston on the

Hexarthrum (for the culinaris, Germ., and the submuri-

catus, Bohm.),and Brachytemnus (for the porcatus, Miill.),

there still remains a residuum, even amongst its smaller

members, which future monographers will in all pro-

bability further divide; yet, having reduced its hetero-

geneous material thus far, and since I am not professedly

in this paper examining every described species (some .of

which would not be readily accessible), I am content to .

leave the group partially pruned, and to treat it as repre-

sented by those particular exponents which I have been

able to inspect, and a list of which will be found in my

general summary at the close of the present memoir. As

thus curtailed, therefore, I believe that Rhyncolus will be

found to possess by no means so universal a range as the

different Catalogues would lead us to conclude,—none of

its members being, apparently, of a large stature. At the

same time, however, I would not wish to imply that its

area of distribution is unnecessarily restricted ; but merely

to call attention to the fact that a vast proportion of the

species which figure as Rhyncoli in various papers and

local enumerations have in reality nothing in common

with the universally-acknowledged generic type.

For the characters which separate this genus from

Phleophagus, with which it has occasionally been con-

founded, the observations which I have given under the

latter will suffice.

113. CavuLopuitus (Wollaston, Ins. Mad. 315. 1854).

—The insect on which this genus was established in 1854,

and which I captured twenty-six years ago in the island

of Madeira, is still unique; and in its general appearance

it somewhat resembles at first sight a small state of the

European Rhyncolus cylindrirostris, Oliv. (= lignarius,

Mshm.). Nevertheless when closely inspected it will be seen

to be structurally dissimilar in many respects; and I doubt

indeed if it can be actually associated with the Rhyncoli at

all. Thus, in addition to its rostrum being obsoletely

divided from the head by a very obscure frontal line, or

depression, its antenne are by no means on the true

Rhyncolus pattern,—their club being considerably larger

and thicker, but nevertheless more acute at the apex,

their funiculus less incrassated (the basal joint being -very

conspicuously smaller, and the terminal ones narrower

and more transverse), and their scape more clavate. Its

eyes also are very much more developed, as well as

Genera of the Cossonide. 587

more approximate (or less widely separated) ; its scutellum

is a trifle larger; and its elytra are somewhat more cylin-

dric or parallel. As in the majority of the Rhyncoli, its

third tarsal articulation is simple.

114. XENOCNEMA (nov. gen.).—It is for an insect from

New Zealand, which has been communicated by Dr. Sharp,

and which was captured by Mr. Lawson in Auckland,

that I am compelled to establish this genus; and there is

perhaps no member of the Cossonide which I have hitherto

examined which is so difficult as regards its affinities,—for

although (as I cannot but think) an undoubted member

of the present family, in the construction of its tibize it is

nevertheless completely Hylastideous. Moreover the first

and second segments of its abdomen are less elongate, and

far more divided, than is the case even in those genera

which shew an unmistakeable affinity with the Hylastide,

the latter of them being (somewhat after the fashion, how-

ever, that we observe in Calyciforus) in a different plane

from the former; and yet in other particulars—as, for

instance, in the increased length and diminished breadth

of its rostrum, its posteriorly-unasperated elytra, and its

unapproximated anterior coxee— Xenocnema is absolutely

more on the normal Cossonideous pattern than such groups

as Stenoscelis, Dendroctonomorphus, and Tomolips, in

which the body is obtusely cylindrical, and more or less

roughened behind, the rostrum exceedingly short and

broad, and the anterior legs practically contiguous. Alto-

gether therefore I am inclined to place it nearer than those

forms to the Rhyncoli and typical Cossonides, whilst at

the same time acknowledging its evident relationship with

the Hylastids in the very significant structure of its tibiee.

These latter indeed are quite unprecedented in any of the

Cossonids which have hitherto come beneath my notice,—

they not only having their tibial hook obsolete (an eccen-

tricity which we perceive in a few exceptional genera, such

as Thaumastophasis, Aorus, and Lipancylus), but (which

is far more important) being expanded towards their outer

apex (more particularly however as regards the four hinder

ones) into a lamelliform spinose process; whilst the inner

angle is armed with a small spur, which (after the manner

so common amongst the Scolytidiens) is developed in the

front pair into a comparatively lengthened sub-horizontal

spine.

588 Mr. T. Vernon Wollaston on the

Apart from these eccentricities of tibize and abdomen,

Xenocnema is remarkable for its rather short and thick,

but somewhat parallel and depressed, body,—which is

densely and sharply sculptured, and of a piceo-ferruginous

hue; for its rostrum (which is robust, but not particularly

abbreviated) being divided by a distinct line (above and

below) from the forehead; for its antennz being almost

medial as regards their insertion ; for its eyes being pro-

minent ; for its prothorax being large, elongate, and sub-

quadrangular ; and for the very unusual sculpture of its

elytra,—the interstices of which are costiform, each costa

however being as it were divided into two by a densely

punctulated central stria.

115. STEREOCORYNES (nov. gen.).—It is the European

Rhyncolus truncorum, Germ., which has afforded the

details for the present genus; and it is surprising to me

how that remarkably-constructed insect could ever have

been associated with the R. ater, and the various other

species on the true Rhyncolus-type. Thus, not only is it

more strictly cylindrical and obtusely rounded behind, but

its rostrum and antenne are on a totally different pattern,

—the former being short and subparallel in the males, but

still shorter and subtriangular in the females ; whilst the

latter (which are inserted considerably behind the middle)

are, as compared with those of the Rhyncoli, exceedingly

abbreviated and glabrous, the scape particularly being

reduced in length, the funiculus-joints closely compacted

together, and the club solid, compressed, and ob-triangular

(being straightly truncated at its apex). In other respects

Stereocorynes is conspicuous for its eyes being extremely

sunken or depressed (instead of prominent as in Rhyn-

colus); for its prothorax being very convex, and quite

unconstricted in front; for its femora, particularly the

front pair, being considerably thickened, and with a faint

appearance beneath of an obtuse anguliform tooth; and

for its four anterior coxe being (as in Hexarthrum) so

manifestly more approximated as to be well nigh con-

tiguous.

116. Hexarturum (Wollaston, Ann. Nat. Hist. v. 448.

1860).—The genus Hexarthrum was established by myself

thirteen years ago for the reception of a Rhyncolus-like

insect, with a 6-jointed funiculus and subasperated elytra,

which had been captured in various houses, and outhouses,

Genera of the Cossonide. 589

at Madeira, and the habits of which seem to be very

similar to those of Pentarthrum and Amaurorrhinus ; and

it is only now that I have been enabled to identify it,

through the examination of more extensive material, with

the European Rhyncolus culinaris, of Germar,—a species

which does not appear to be common in collections, or

one which is very extensively known. Nevertheless I can

detect no difference between the Madeiran insect and

a type of the latter which has been communicated by

Mr. Gray; and I do not hesitate therefore in regarding

them as identical. Yet the generic characters of Hexar-

thrum remain clear and well defined, and afford another

instance of the loose manner in which so many discordant

forms have been associated with the Rhyncoli, and of the

little care which appears to have been bestowed by certain

Coleopterists on the structural features of their published

species.

So far as I am aware, Hexarthrum is the only member

of the Cossonide (outside the very anomalous subfamily

Onycholipides) in which the funiculus is composed of only

six articulations; and it is further remarkable for its

rostrum being short and narrowly subtriangular, for its

antenne bring greatly abbreviated (even more so perhaps

than in Stereocorynes ), for its elytra being shortly cylindric,

obtusely rounded behind, and subasperated (particularly

as regards their posterior half), and for its four anterior

coxe being subcontiguous. As in Stereocorynes and

Tomolips, its antenne are not only much reduced in length

(especially the scape), but are likewise glabrous, and with

the funiculus-joints very closely compacted together ;

nevertheless the club is more rounded, or less apically-

truncate, than in those genera. Its prothorax also (which

is unconstricted in front) is nearly unmargined at the

base ; its first and second abdominal segments are divided

by an unusually distinct line; and its entire surface,

although appearing quite bald, will be seen, when viewed

beneath the microscope, to be very sparingly besprinkled

(which is not the case in Stereocorynes and Tomolips) with

a short and most minute pubescence.

I may state that a Hezxarthrum has been detected

lately by Mr. G. Lewis in Japan, closely allied to (but

nevertheless unquestionably differing from) the European

and Madeiran H. culinare ; and also that the European

Rhyncolus submuricatus, Bohm., appears, if I may trust

an example now before me from the collection of John

Gray, Esq., and which almost completely satisfies the

published diagnosis of that insect, to be likewise a Hez-

arthrum,

117. Tomorires (nov. gen.).— With the exception of

Pentamimus from Australia, the present genus offers the

only exception (as far as I have hitherto observed), outside

the subfamily Pentarthrides, in which the funiculus is

composed of but five joints; nevertheless it is so manifestly

related to Hexarthrum (in which that organ is 6-articulate),

and likewise to the sub-Hylastideous groups around Bra-

chytemnus, that it is as impossible to consider it a Pen-

tarthrid as it would be to place Hexarthrum (on account

of the number of its funiculus joints) amongst the anoma-

lous types of the Onycholipides. And hence, so long as

a natural arrangement (and not a purely artificial one) is

to be aimed at, I have practically no choice left me but to

treat it as an exception in the subfamily Cossonides. It

is a significant fact however that its nearest known ally

should be a genus in which the funiculus-articulations are

likewise reduced in number,—in that instance however

(from the normal seven) to szz ; and it would look therefore

as if these immediate forms were subject par excellence (in

that particular respect) to instability. Be this however as

it may, I will merely repeat that the two genera in question

(namely Hexarthrum and Tomolips) are, with the excep-

tion of Pentamimus and Tatracoptus, the only instances,

so far as I am aware, in the present subfamily, in which

the funiculus is otherwise than 7-jointed,—it beg com-

posed of six articulations in the one, and of five in the

other.

But, apart from this primary peculiarity in the structure

of its funiculus, Tomolips is somewhat osculant between

Hexarthrum and the strictly sub-Hylastideous genera—in

which the rostrum is extremely short and broad, the eyes

are less widely separated, and the sculpture is remarkably

coarse ; whilst in the obtriangular shape of its solid and

compressed club it shews an equal affinity with the

European Stereocorynes. However its posteriorly-aspe-

rated elytra is a character of considerable importance, and

one which is likewise indicated (though to a less extent) in

Hexarthrum. In its glabrous antenne (the scape of

which is much abbreviated, and the funiculus very com-

pact), as well as in its four anterior coxee being nearly

contiguous, it is in perfect accordance with these imme-

Genera of the Cossonide. 591

diate forms ; but in its elytra being more produced (or less

obtusely-rounded) behind, in its shoulders being rather

suddenly and acutely porrected, and in the front tibie of

its type being armed at their inner angle with a compressed

bifid spur, there is a singularity about it which is essen-

tially its own. The two species of Tomolips which are

now before me were taken in Mexico, and are from the

collection of Mr. Fry.

118. DENDROCTONOMORPHUS (nov. gen.).—It is for a

Hylastes-, or Dendroctonus-like Cossonid from Ceylon,

which (together with an allied species from Malabar,

and a rather less typical one from Mexico) has been com-

municated by Mr. Fry, that I have been compelled to

establish the present genus. In its structural peculiarities

it is somewhat intermediate between Brachytemnus and

Stenoscelis,—agreeing with the former in its conspicuous

(though less largely developed) scutellum, comparatively

elongate, almost unconstricted prothorax, the general

character of its sculpture (which however is not quite so

coarse), and in its perfectly simple third tarsal jot; but

with the latter in its asperated elytra, greatly lengthened

feet, more widely separated eyes, and less glabrous an-

tenn. In its thickened head, short, triangular rostrum,

sunken eyes, and cylindrical body, it is in accordance with

the whole of these sub-Hylastideous forms.

119. BRACHYTEMNUS (nov. gen.). — It is in order to

receive the European Rhyncolus porcatus, Miill., and my

nearly-allied R. pinipotens from the Canarian archipelago,*

that I have proposed the present genus; and it seems mar-

vellous to me now how those curious insects could ever

have been included amongst the Rhyncoli—from which

they appear to differ in nearly every detail of their

* My B. pinipotens (= crassirostris, olim), which I captured in an old °

fir-tree in the island of Grand Canary, is most closely allied to the B. por-

catus, Mull., of Southern Europe. Its rostrum and prothorax however (the

former of which is free from an anterior channel, whilst the latter is less

sinuated on either side behind the middle) are just appreciably less coarsely

and more sparingly punctured; its elytra (which have the shoulders less

porrect) are a trifle more parallel, there being apparently no tendency to

be even obsoletely widened posteriorly, and have their apical region less

obtusely-desilient (or suddenly bent-downwards) ; and the club of its an-

tenn is rather more truncated in front. The underside also is somewhat

less grossly punctured, and the first abdominal segment, which is convexer,

is likewise a little more remotely so.

592 Mr. T. Vernon Wollaston on the

structure. Indeed in its thickened head, abbreviated,

subtriangular rostrum, and depressed eyes, no less than in

its greatly shortened antennz and its long and slender feet,

the genus has very much the sub-Hylastideous aspect of

Stenoscelis: and it may be defined therefore to differ

essentially from Rhyncolus in its much shorter and more

triangular rostrum; in its larger and more sunken eyes,

which are appreciably less lateral (or more sub-approxi-

_mated above); in its prothorax being altogether more

cylindrical and developed; in its very much more abbre-

viated antennez (the scape of which is so reduced in length

as to be even shorter than that of Stenoscelis,—indeed as

short as in the European genera Stereocorynes and Hexar-

thrum, or as in Calyciforus and Eurycorynes from Brazil),

the club of which, although compressed, is exceedingly

rounded, solid, and abrupt; in its first and second abdo-

minal segments being much more conspicuously divided

from each other; in its legs and tarsi being slenderer

(with the tibial hook more straightened, and the basal

joint of the latter rather more elongate); and in its cox

being more approximated,—the four hinder ones, in fact,

being nearly contiguous. In its scutellum however being

conspicuous, Brachytemnus recedes from Stenoscelis, and

agrees better with the other immediately-allied forms.

120. CALYcIFoRUS (nov. gen.).—The very extraordinary

insects, which have been communicated by Mr. Fry and

Mr. Janson, for which the present genus is established,

and which were captured in the provinces of Rio Janeiro

and Bahia in Brazil, are amongst the most remarkable

members of the Cossonide with which I am acquainted ;

and yet their affinities are, unquestionably, with such forms

as the European Brachytemnus, Eurycorynes from Brazil,

and Stenoscelis—from S‘. Helena, Southern Africa, and

Japan. Indeed in its thickened head, short, subtriangular

rostrum, and sunken, subapproximated eyes, as well as in

its excessively abbreviated antenne, its slender, filiform

feet, and the fact of its four anterior coxz being nearly

contiguous, the genus has much marvellously in common

with the first of those groups; nevertheless the compara-

tively large size of its members, and the deep and anoma-

lous triangular excavation in the middle of their prothorax

behind (immediately in front of the greatly developed

scutellum), added to the extraordinary sculpture of their

elytra (the sulci of which are wide, deep, opake, and

Genera of the Cossonide. 593

transversely strigose, whilst the interstices are broad,

costate, and shining, and studded with a single series of

large subasperated punctures), and their short, transverse,

abrupt, anteriorly-truncated, cup- (or somewhat calyx-)

shaped capitulum, are all of them characters which are

essentially their own. In its prothorax being comparatively

unconstricted in front Calyciforus is, likewise, on the

Brachytemnus-type; nevertheless it is impressed ante-

riorly in the centre (which is not the case in that genus) ;

and both the prothorax and elytra are coarsely margined

at their respective bases. Its four anterior tibis are armed

at their inner angle with a robust spine; and the hooks

of all of them are powerfully developed. Its feet are as

slender as, and if anything even more elongated than, in

Stenoscelis ; but their third joint is still narrower and more

entire, being perfectly simple.

121. EuRYCORYNES (nov. gen.).—I am indebted to

Mr. Janson and Mr. Fry for the remarkable Cossonid

from which the details for the present genus have been

drawn-out; and it has given me much pleasure in dedi-

cating the species to the former of these eminent Cole-

opterists. Like Calyciforus it is South-American, having

been received by Mr. Janson from the province of Minas

Geraes in Brazil; while Mr. Fry’s example appears to

have been taken by himself near Rio Janeiro; and it is at

once conspicuous for the very unusual structure of. its

greatly abbreviated antennze,—the scape of which has the

joints gradually more and more transverse and lamelliform,

the last one of them being so thin as to he only just appre-

ciable against the enormously enlarged club. This latter

is most peculiar,—being exceedingly wide, transverse, and

abrupt (more so indeed than in any member of the family

with which I am acquainted). In its thickened head, and

in the shortness of its triangular rostrum and antenne, as

well as in its sunken eyes and elongated slender feet, Eury-

corynes has much in common with Brachytemnus, Caly-

ciforus, and Stenoscelis ; but it agrees best with the last

of those three genera in the fact of its scutellum being

nearly obsolete, and in its elytra being asperated (though

less so, and in a different manner) both before and behind.

Nevertheless, in reality, it is perhaps nearer to Calyci-

forus,—with which it agrees in its eyes being less widely

separated on the forehead, in its prothorax being less short-

ened, in its elytra being broadly sulcated (though not quite

594 Mr. T. Vernon Wollaston on the

so coarsely so as in that group), with their costate inter-

stices branded with a row of conspicuous subasperated

punctures, in its four anterior cox (although very closely

approximated) not being quite contiguous, and in the third

articulation of its feet not being in the slightest degree

widened, and remarkably simple. ‘The punctation of its

head and prothorax is extremely dense and substrigulose ;

and the latter has a polished line, or faint keel, evanescent

before and behind, down the centre.

122. STENOSCELIS (Wollaston, Journ. of Ent. i. 141.

1861).—Of all the Cossonids which have hitherto been

described, perhaps Stenoscelis makes the nearest approach

to the sub-Curculionideous forms of the Hylastide,—its

shortly cylindric body, which is a little asperated (as well

as just appreciably widened, and obtusely rounded) poste-

riorly, having much in common with such genera as

Dendroctonus. In its thickened head, short, triangular

rostrum, and sunken eyes, as well as in its exceedingly

abbreviated antennze and its elongated slender feet, it is

on much the same pattern as the three preceding groups ;

nevertheless its prothorax is shorter, or more transverse,

more constricted anteriorly, and subsinuate on either side

in the middle, its four anterior coxz are more completely

approximated, and the third joint of its feet (although

scarcely at all widened) is not quite simple,—being evi-

dently, though minutely, bilobed. In the fact of its

scutellum being nearly obsolete it has a greater affinity

with Lurycorynes than with Calciforus or Brachytemnus ;

but its capitulum (which is oval, and on the ordinary type)

is not in any degree anomalously developed, and agrees

better therefore with the last of those three genera. The

three exponents of it which have been hitherto detected

are from the island of St. Helena, the Cape of Good

Hope, and the Japanese archipelago.

Election of Member.

William Cole, Esq., of 10, Aberdeen Terrace, the Downs, Clapton, was’

balloted for, and elected a Member of the Society.

Exhibitions, dc.

Mr. F. Smith brought for exhibition a box of Indian Hymenoptera

collected by Mr. Rothney at Nuddea, in the district of Minchindipore,

about eighty miles from Calcutta. It comprised about 200 specimens

of Fossores, 160 Apide, and 230 Formicidae. Of the Fossores there were,

apparently, only two undescribed species out of about forty, and the same

with the Apide; but amongst the species of Formicidé there were eight or

ten which appeared to be undescribed. They were all in extremely fine

condition ; the most interesting species in the collection being a new Astata,

and four or five beautiful species of the genus Nomia among the bees.

Mr. M‘Lachlan exhibited the quadrangular case of the larva of a

Trichopterous insect, together with the larva itself, preserved in glycerine.

These had been placed in his hands by the Rev. A. E. Eaton, who found

them in the Dove, a swiftly running stream in Derbyshire. He supposed

it to pertain to Brachycentrus subnubilus, as the larve of that species were

now known to manufacture quadrangular cases. Mr. Eaton, however,

stated that he was not quite satisfied that the case and larva found by him

were actually those of Brachycentrus, for he had uever seen that genus in

the part of the Dove in which he found them, though it occurred lower

down the stream.

Mr. Champion exhibited specimens of a large species of Pulex found by

Mr. F. Walker in a mouse’s nest in the Isle of Sheppy.

Mr, Bird exhibited a specimen of Cerastis erythrocephalus, taken on the

28th of October last at Darenth Wood.

Mr. Meldola exhibited a living specimen of a myriapod of the genus

Spirobolus, which had been sent to him from San Francisco. Also eggs of

a leaf insect (Phyllium pulchrifolium) from Java. He also shewed a

specimen of a Noctua impaled on a thorn, supposed to have been done by a

shrike. Mr. Weir was inclined to think that, in this case, the insect was so

impaled; but he believed that insects were frequently impaled by other

means.

Mr. Pascoe called attention to a remark made by Mr. Walker in the

February part of the ‘ Entomologist,’ to the effect that the fireflies (Lucciola

Italica), seen in abundance in Italy, had probably entered that country from

the East, and were hindered by the Maritime Alps from occupying the

Mediterranean coast of France. He (Mr. Pascoe) had seen the insect in

abundance in France between Cannes and the Var, and was desirous of

ascertaining if any entomologist had noticed it further westward in France.

Mr. Albert Miller communicated the following notes regarding the

originators of the pouch-galls on cinnamon :—

‘On the 4th of March, 1872, I exhibited before the Society some

specimens of an open pouch-gall on the leaves of Cinnamomum nitidum,

from Bombay; and in a note on the subject (Proc. Ent. Soc. Lond. 1872,

p. ix., and ‘ Zoologist,’ 1872, p. 3036), I was inclined to attribute them-

probably to the action of a mite, belonging perhaps to the genus Phytoptus.

“Tn reference to this question, my valued correspondent, Dr. Fr.

Thomas, to whom I had communicated the said note, has since expressed

the opinion that it will have to be tested by further observations, whether

the gall owes its origin to a mite, and that he doubts it (Giebel’s Zeitschr.

f. d. ges. Naturwissensch. 1872, p. 475).

“Tam quite of the same opinion as my learned friend, that the matter

requires further elucidation, but residents in the East can best solve the

riddle, either by careful investigations on the spot, or by the transmission

of materials to Europe.

‘This seems the proper place to allude to the fact that an allied, if not

identical creature, attacks the leaves of cinnamon bushes in Ceylon. John

Nietner has placed on record that in the neighbourhood of Colombo, where

there exist old Dutch plantations of cinnamon bushes, 6000 to 8000 acres

in extent, the bushes often form a single, monstrous, tangled mass, their

leaves being curled up by numerous swellings of the size of peas or beans.

The acorn-shaped fruits of the same plant are often similarly affected,

swelling up until they assume the size and colour of a walnut. Nietner

puts the question whether these excrescences might not be the work of a

Cynips; but as he subsequently compares them to the bulged-out leaves of

some species of Ribes, inhabited by Aphide, we must leave his former

supposition out of consideration (Stettin Ent. Zeitung, 1857, p. 39).

“Tn a letter which I have since received from Dr. Thomas, this gentle-

man expresses his supposition that the Bombay excrescences may be

produced by one of the Psyllodes. If we bear in mind what Nietner says of

the Singalese form, Dr. Thomas’s opinion undoubtedly becomes entitled to

much consideration, and may eventually turn out to be founded in fact.

For my own part I prefer to suspend my judgment until fresh materials

from the East shall have enabled me to examine the excrescences in

question, as well as their inhabitants, more in detail.”

The Rev. Mr. Eaton stated that he had had a specimen of a Trombidium

given to him, which had been taken by Mr. Benjamin Lee Smith, in Sep-

tember last, at Spitzbergen.

Donations to the Library.

The following donations were announced, and thanks voted to the

donors :—‘ Illustrations of Diurnal Lepidoptera,’ part v. Lycenide ;

Fennica’; by the Author, F. W. Woldstedt.

Election of Members.

Alfred E. Hudd, Esq., of Redland Park, Bristol (formerly a Subscriber),

was balloted for and elected an Ordinary Member; and Dr. Hermann Bur-

meister, of Buenos Ayres, was elected a Foreign Member of the Society.

Exhibitions, &c.

Mr. I’. Bond exhibited a series of bred specimens of Acronycta tridens

and A. Psi, with preserved larve of the two species. The specimens of

A. tridens had all been reared on the common pear. He remarked that

the dark specimens so often occurring in A. Psi were never repeated in

A. tridens ; and that the latter always exhibited a pinkish tint in fine fresh-

bred specimens, which, however, was very evanescent.

Mr. Miiller exhibited some cases of a species of Psyche, formed of

twigs arranged spirally, and also the egg-case of a species of Mantis; these

had been sent from Calcutta by Mr. G. A. James Rothney.

Professor Westwood exhibited two Dipterous larve preserved in spirits

which were probably those of Psila rose. These had been discharged by

a female in a clot of phlegm. He suggested when they were submitted to

him that the person had probably been eating raw carrots, which, upon

enquiry, turned out to have been the case. After they had been immersed

in spirits for three or four days he took them out for examination, when he

was surprised to find they were still alive. He also exhibited drawings of

a dipterous larva (probably Merodon clavipes, Fab.) infesting some bulbs

sent to him from the Continent. Also drawings of woody excrescences on

stems of vine, which had probably been formed by a beetle of the genus

Otiorhynchus. Mr. Miller remarked that Mr. Riley had recorded a similar

habit in an American beetle (Baridius Sesostris, Lec.).

Professor Westwood further exhibited drawings of the root-fibres of a

vine, dilated and constricted in a joint-like manner, which he thought was

owing to former attacks of Phylloxera.

Mr. Briggs exhibited parallel series of the large and small forms of

Anaitis plagiata taken by him in Tilgate Forest, in the month of June,

stating that he had found only the larger form last year, in the same place

in which he had found only the smaller form three years before. It was

commonly supposed that the smaller form was only a second brood, but this

did not appear to be the case.

Mr. F. Smith read the following translation of some notes, “ On the

Salivary Organs of the Honey Bee,” by C. Th. y. Siebold :—

“ At the annual agricultural meeting held in October, 1871, at Munich,

a well-known apiarian, Herr Mehring, had exhibited a peculiar kind of

honey, named by him ‘ Kunst-Honig’ (artificial honey), which he had pro-

duced by feeding his bees exclusively with malt. This honey excited great

interest; and the question was raised (and denied by many), whether this

substance was real honey ; and whether, consequently, the bee was able to

change malt-sugar in its stomach into honey. The physiologico-chemical

part of the inquiry into the production of the bee was taken up in Liebig’s

laboratory by Dr. Von Schneider, who, unfortunately, was prevented from

carrying the investigation to the end, but arrived at the conclusion that

the hydrates of carbon (malt-sugar and malt-deatrin) contained in the malt

are actually changed by the bee into honey-sugar; and that Mehring’s

honey does certainly not differ from other honies, except in the absence of

specific aromas which are imparted to them from the flowers on which the

bees have been collecting. Practically, Herr Mehring’s discovery is of

importance ; inasmuch as the malt-food prepared by him contains not only

all the ingredients necessary for the life of the bee, but also for the forma-

tion of honey; and therefore can be used with advantage in parts of the

country where flowering plants are scarce. With regard to the wax, Dr.

Von Schneider maintains that it is undoubtedly a secretion of the honey-

bee, formed chiefly out of different kinds of sugar ; but that the production

of wax from sugar is not continued without the simultaneous addition of

food containing nitrogen. After the fact had thus been established that honey

and wax are not substances found ready made, and simply gathered by the

bee; but productions which have undergone chemical changes through

having come in contact with the secretions of the insect; Prof. Von Siebold

directed his attention to the investigation of the secreting organs, a portion

of the anatomy which, indeed, had previously been entirely neglected, but

is now treated for the first time with regard to the special functions those

organs appear to perform in the preparation of the products of the bee.

Vil

Prof. Von Siebold distinguishes three entirely distinct and very complicated

systems of salivary glands; two of which, a lower and an upper, are situated

in the head, and the third in the anterior part of the thorax, the latter

having been erroneously regarded by Fischer as a lung. Each of them has

separate excretory ducts, and is distinguished by a specifically different form

and organization of the vesicules secreting the saliva. Each consists of a

right and left glandular mass, with right and left excretory ducts.

“For the detailed account of their minute structure we must refer to the

paper itself, and the plate accompanying it, but we must add that this extra-

ordinary development of the salivary organs has been observed by Prof.

Von Siebold in the workers only. The queen possesses only a rudiment of

the lower cephalic system in the form of the two orifices of its ducts,

whilst the ducts themselves with the glands are absent ; and the two other

systems are much less developed than in the workers. In the drones not

even the orifices of the lower cephalic system could be found.” (Bienen-

zeitung, 1872, No. 28).

Mr. Meldola, at the request of Mr. J. Jenner Weir, referred to the chemical

composition of malt-sugar as compared with sugar in honey. It was stated

that malt-sugar had the same composition as glucose; while honey, in

addition to glucose, contained cane-sugar or saccharose. Mr. Weir remarked

that it was an interesting fact that this chemical transformation of malt-

sugar into a sugar containing a different percentage of carbon should take

place in the economy of the honey-bee.

Mr. Smith read ‘ Descriptions of Aculeate Hymenoptera of Japan, col-

lected by Mr. Geo. Lewis, at Nagasaki and Hiogo. Of seventy-three species,

forty-nine were previously unknown. He remarked that the distinctness of

his Apis nigrocincta from A. mellifica, recently questioned by Dr.

Gerstiacker, had been abundantly confirmed by the discovery of a queen of

A. nigrocincta.

Exhibitions, éc.

Mr. Howard Vaughan exhibited a box containing about two hundred

specimens of Japanese Lepidoptera, collected near Yokohama by Mr. Henry

Pryer; many of the species being apparently new. Some also were re-

markable as bearing a close resemblance to British species. Mr. Moore

noticed a strong Indian character in several of the insects.

The President remarked that Mr. Higgins had shown him a specimen of

a Cremastocheilus from Japan, which was identical with a species that had

been taken by Mr. Lord on the West coast of North America.

Mr. F. Smith exhibited some insects bearing a most remarkable re-

remblance to each other, although belonging to different orders. Thus,

Euglossa dimidiata and another Euglossa, a Genus of Apide, bore a striking

resemblance to two species of the Dipterous family Asilide, namely,

Dasyllis hemorrhoa and Mallophora tibialis, all from South America.

Also, Abispa splendida, one of the Vespide, and an insect of the Dipterous

genus Lachites(?), both from New Holland. Also, a bee of the genus

Megachile, and one of the Asilidze, Mallophora calida, Wied., from South

America. With regard to the two last-mentioned insects, Mr. Smith noticed

that the Asilus not only resembled the bee in its general appearance, but

that also it was furnished on the under side of the abdomen with a brush

similar to the pollen-brush of Megachile; although it was not apparent for

what purpose the insect required it.

The President remarked that when he was at Casa Brucciata, near

Ancona, he observed several insects of the genus Osmia extracting the black

pollen from poppies; and on the sandy shore he noticed the same insects

collecting the sand on their ventral brushes. He therefore concluded that

the brushes were used, not only for collecting the pollen, but also for

carrying the grains of sand to their nests, which he observed them in the

act of constructing on walls. ;

Mr. Champion exhibited specimens of Bagéus brevis, Schawm ; taken in

this country by Dr. Power, although not hitherto observed in Britain.

Mr. Miiller directed attention to an article in the last number of the

‘Petites Nouvelles,’ explaining a method of obtaining silk from cocoons

which had been eaten through by the insects; and that the silk so obtained

vili

from the damaged cocoons was equal in quality to that obtained from the

perfect cocoons, and did not require to be carded.

The President remarked that the library at the new Museum at Oxford

had been very much infested, of late, with Anthreni; and he was very glad

to observe that there was a paper by Dr. Emery in the ‘ Bulletino della

Societa Entomologica Italiana,’ on a new method of preserving collections

from their ravages,

Exhibitions, é&e.

The President exhibited a specimen of a very rare species of Paussus from

Abyssinia, in which the hinder part of the thorax was constricted, quite

unlike any of the other species.

Mr. F. Smith exhibited a further collection of ants sent by Mr. G. A. James

Rothney, from Calcutta. They were collected by him in a very restricted

area, principally in the Eden Gardens, Calcutta, between the months of

June and October of last year. ‘The specimens which Mr. Smith had been

able to determine were thirty in number, namely :—

Formicidé (eight species).— Camponotus compressus, Fabr.; OC. syl-

vaticus, Oliv.; C. opaciventris, Mayr, n.sp.; C. Bacchus, Smith; Polyrhachis

spiniger, Mayr., n. sp.; P. Shrinax, Roger; P. levissimus, Smith ; C&co-

phylla smaragdina, Fabr. Poneride (six species).—Bradyponera longitarsis,

Mayr., nu. gen. & sp.; Lobopelta chinensis, Mayr.; L. mutabilis, Smith ;

L. punctiventris, Mayr., n. sp.; L. diminuta, Smith; Diacamma vagans,

Smith. Myrmicide (fifteen species)—Crematogaster Rothneyi, Mayr, n. sp.;

wear

Hypoclinea gracilipes, Mayr.; H. excisa, Mayr.; Holcomyrmex indicus,

Mayr., n. gen. & sp.; Pheidolacanthinus levifrons, Mayr., n. sp.; Mono-

morium latnoda, Mayr.; Solenopsis geminata, Fabr.; Pheidologeton labo-

riosus, Smith; Pheidole javana, Mayr.; Typhlata tricarinata, Mayr., n.sp.:

T. brevicornis, Mayr., n. sp.; Sima rufonigrum, Jerdon ; S. atrata, Smith ;

S. carbonaria, Smith ; Myrmicaria subcarinata, Smith. Cryptocerid@ (one

species); Meranoplus bicolor, Guer.

Thus, there were nine new species, two of which were new genera, and

the collection contained several others, apparently new, requiring further

examination. Mr. Smith directed attention to the fact that Mr. Rothney

had very carefully collected the sexes of the different species, which was of

the utmost importance to Science. Mr. Rothney had also, in a most liberal

manner, allowed Mr. Smith to select a complete series of specimens for the

British Museum.- Connected with Mr. Rothney’s collection were also three

examples of what appeared to be the ant, Sima rufonigrum, placed side by .

side; but on close examination one of them was found to be a spider

of the genus Salticus, having its anterior legs purposely removed, causing

it to present a striking resemblance to the ant, which, like it, inhabits

trees.

Mr. William Cole exhibited some magnificent species of Bombycide

collected by Dr. Seaman, near Pine Town, Port Natal.

Mr. Stevens remarked that a hybernated specimen of Vanessa Antiopa

had been seen on Sunday last in a church at Redhill.

Papers read, éc.

Mr. Bates communicated “ Descriptions of New Genera and Species of

Geodephagous Coleoptera from China, founded principally on Collections

made by Mr. George Lewis.”

Mr. Albert Miller communicated the following notes :—

1. Araocerus coffee at Basle —“ On the 29th of September, 1862, while

attentively watching the unpacking of some freshly-imported bags of Java

coffee, in a warehouse at Basle, a very lively specimen of this beetle

came tumbling out of one of the bags. I secured it and kept it alive

for some days. In a letter dated the 14th of March, 1878, which

I have just received from my lynx-eyed friend Herr H. Knecht, of the

same city, he tells me that he can now get this species in any

quantity at Basle. It is well known that this species of Anthribide

feeds in the larval state on raw coffee-berries; hence its introduction

and capture in commercial emporia on the coasts of different continents

need cause little surprise; but the two facts here recorded illustrate once

more the indubitable axiom that insects living on merchandise are spread

chiefly along the main trade-route, and become acclimatised along their

whole course, Basle being one of the chief markets where Central Europe

stores and disposes of the purchases derived from Mediterranean and

Atlantic ports.”

2. Tribolium ferrugineum in Ground-nuts.—*< In the summer of 1863 a

cargo of ground-nuts (Arachis hypogea) arrived in the port of London direct

from Sierra Leone. On arrival the usual samples were drawn, when it

turned out that the husks were riddled by countless holes, while the kernels

were half eaten up by myriads of larvee and imagines of Tribolium ferru-

gineum. So completely had they done their noisome work that in the

numerous samples examined scarcely an intact kernel could be found. If

a nut was opened the whole interior was often found to be converted into a

living conglomerate of larve, pupe and imagines of Tribolium, accompanied

by the larve and perfect insects of a Rhizophagus preying on the former, —

the whole mass being wrapped up in a layer of cast-skins and excrement.

As no purchaser could be found, owing to the deplorable state of the cargo,

the work of destruction continued through the months of August, September

and October, the owners being unwilling to take a considerably lower price

than had been calculated upon. A fresh proof how the marketable value of

an article can become reduced through delay and ignorance on the part of

its owner.” ~

Mr. Dunning read the following “ Further Note on Atropos pulsatoria,

with reference to Dr. Hagen and Mr. W. A. Lewis.”

“There is on the table this evening an abstract of Mr. Lewis's paper,

“On Dr. Hagen’s treatment of Atropos pulsatoria and Termes fatidicum”

mens. ail

(Proc. Ent. Soc. 1872, p. xl.), in answer to some remarks I made on the ~

4th November, 1872. If the Society is not weary of the subject, I should

like to say a few words, and will be as brief as possible.

‘“‘Sympathising with Mr. Lewis in what I conceive to be the main pur-

pose of his ‘ Discussion of the Law of Priority,’ but feeling that a good

cause ought not to be supported by a misrepresentation of facts, I ventured

to point out what I considered, and still consider, to be an error on Mr.

Lewis's part. And I certainly was sanguine enough to expect that when

the mis-statement was pointed out, it would be at once withdrawn.

“ However, Mr. Lewis does not see the matter in this light, and contends

that he has made no error of the kind I supposed. He says that I have

written in the language of apology only the same things which he has

written in the language of fault-finding; that I have concluded he was

under some misconception from failing to understand that he considers

worthy of reprobation what I pass by as nothing; that I have come forward

to justify Dr. Hagen for having published a Synopsis of the British Psocide

without an investigation of the species.

Sah

“Tf this be a fair account of what I said, my meaning must have been

very ill-expressed. I refer to Proc. Ent. Soc. 1872, p. xxxiv., for what I did

say, and will only add that I lent Mr. Lewis the MS. of my paper to prepare

his reply. If the above be his understanding of what I have written, I can

scarcely feel surprised that he has misrepresented Dr. Hagen.

“Mr. Lewis would have it appear that we are ‘at difference not upon

facts, but upon the importance attached to them.’ The statements which

I challenged were these—that ‘the Atropos of 1861 is the Clothilla of

1865,’ that ‘the insect which [in 1861] had a bare back, 15-jointed

antennz, and thickened thighs, has now [?.e. in 1865] leather-like

winglets, 27-jointed antenne, and legs not thickened,’ and that ‘the same

insect is described by Dr. Hagen twice over, on two adjoining pages, with

opposite structural characters.’ I say that these statements are erroneous ;

and if that is not a difference upon facts, I am at a loss to conceive

what is.

“ But how does Mr. Lewis meet my challenge? He says, ‘ Mr. Dunning

proves that the Linnean name pulsatoria was in 1865 transferred to an

insect of the genus Clothilla, while in 1861 it has represented an insect of,

the genus Atropos. Granted at once; and therefore the Atropos of 1861

is the Clothilla of 1865. The very same “ pulsatoria, Linné,” was in 1861

described as an Atropos, and was in 1865 described as a Clothilla.’

Mr. Lewis must entertain a very low estimate of the intelligence of ento-

mologists if he thinks they will be convinced by such a verbal quibble.

Entomologists describe insects, and apply names to the insects; they do

not describe names, and attach insects to the names. On two different

occasions Dr. Hagen applied the same name to two different insects having

opposite structural characters, on each occasion describing the two insects,

and describing them as having opposite structural characters. And Mr.

Lewis gravely contends that ‘the same insect is described by Dr. Hagen

twice over, on two adjoining pages, with opposite structural characters’ !

Because insect A with one set of characters was at one time called ‘ pulsa-

toria, Linné, and insect B with another set of characters is at another time

called ‘ pulsatoria, Linné,’ therefore (says Mr. Lewis) the same insect is

described twice over with opposite structural characters! It has never

been my lot to encounter a more charming Non sequitur. And on this,

and on this alone, Mr. Lewis has founded the charge of ‘astonishing

chicanery’ of which Dr. Hagen is said to have been guilty.

“ Mr. Lewis says that I have not answered the more important of his two

cases, that the criticism impugned by me was based on two instances, but

especially on that of Termes fatidicum, which is the climax to which Atropos

pulsatoria was only a step. It is true I did not answer what Mr. Lewis

said about Termes fatidicum; my object was to correct a specific mis-

statement, which related only to Atropos pulsatoria. On reference to the

‘ Discussion,’ it will be seen that Dr. Hagen’s treatment of T. fatidicum was

a ‘RIDICULOUS FARCE,’ but his treatment of A. pulsatoria was ‘astonishing

chicanery.’ To me the word ‘chicanery’ has an ugly sound; it was that

word which offended my ear, and it was to the charge of chicanery that

I addressed myself. And the charge then made as to A. pulsatoria having

been (as I submit) refuted, Mr. Lewis now brings T. fatidicum to the front,

and makes a lot of fresh charges based on Dr. Hagen’s treatment of this

insect, or if Mr. Lewis prefers it ‘this supposed insect.’ It is as if my

learned friend were prosecuting a man (say) for bigamy, and after the

defence has been heard, the prosecutor replies by attempting to show that

the accused has at all events committed forgery! As before, I decline to

discuss the ‘ FaRcE,’ preferring to attend to one thing at a time.

“Mr. Lewis goes on to say, ‘It is the gist of my complaint that

Dr. Hagen taught me in 1861 the exact opposite of what he taught me in

1865, though all the same materials were to his hand at the one time as at

the other. J am in my turn surprised that Mr. Dunning should think this

amounts to nothing.’ Mr. Lewis’s surprise is uncalled for; Mr. Dunning

has neither said that this amounts to nothing, nor does he think so. The

ground now alleged may or may not be a good ground of complaint against

Dr. Hagen; but it is quite a different complaint from that which was made

in the ‘ Discussion,’ p. 54. The original objection was that the change of

name ought not to have been made at all; the objection now is that

Dr. Hagen ought to have known in 1861 the facts which induced him to

make the change in 1865. ‘The simple fact is that in 1861 Dr. Hagen

published a Synopsis of the British Psocide without an investigation of the

species. That is the back-bone of Mr. Dunning’s remarks, and is, I pre-

sume, the thing he has come forward to justify.’ Mr. Lewis presumes too

much; I have not attempted to justify what Dr. Hagen actually did, much

less have I come forward to justify what Mr. Lewis, without any personal

knowledge of the circumstances, asserts to be ‘ the simple fact,’ but which

of my own knowledge I say is not a fact. If Mr. Lewis's simple fact’is the

back-bone of my remarks, the back-bone was very carefully extracted, and

“my remarks as delivered were invertebrate. Upon what authority, or

supposed authority, it is stated that Dr. Hagen published his Synopsis of

1861 without an investigation of the species, I cannot conjecture. But if

there be any question on this point, it is fortunate that there are still living

several entomologists who can testify to the fact of the investigation having

been made. In truth, Dr. Hagen came over to this country for the very

purpose of studying the British species.

“That subsequent investigation has proved the existence of errors in the

Synopsis of 1861 is perfectly true. But faulty as it was, it did good service

in its day; and no one has more readily admitted its shortcomings and

corrected its errors than Dr. Hagen himself, To my mind, readiness to

xill

admit and correct one’s own mistakes is praiseworthy, not blameworthy,

I have no greater love for error than Mr. Lewis has, but I hope I am a little

more tolerant of the mistakes of others than he is. All mistakes are to be

~ regrettel; but when made, and afterwards found out to be mistakes,

sprciy the best thing is to correct them. It can scarcely be contended that

“no one should publish anything until there is a certainty of freedom from

mistake: on this principle, what would the present state of Science have

been? Certainly if Mr: Lewis had waited until he attained immunity from

blunder, we should not have had the satisfaction of reading his ‘ Discussion’

in the year of grace 1872.”

Mr. Bates put some questions to the meeting, suggested to him by

Mr. Darwin, with a view to eliciting information as to sexual differences in

insects furnished with ocellated spots; and also as to sexual differences

among the Buprestide. A conversation ensued, in which Mr. Jenner Weir

stated that in Satyrus Hyperanthus the spots were more numerous in the

female than in the male, and Mr. Butler remarked that Drusillus had

double spots in one sex. It was also stated that Mr. Saunders had detected

corresponding sexual differences in the Buprestide.

Election of Member.

Mr. Edward Cracroft Lefroy was balloted for and elected a Member of

the Society.

Exhibitions, &c.

Mr. Champion exhibited specimens of Tribolium confusum and Ptinus

testaceus, which he had observed in British collections mistaken for

Triboliam testaceum and Ptinus fur.

Mr. Verrall exhibited a specimen of Laphria flava, L., one of the Asilide,

taken in Scotland, not having been hitherto discovered in this country.

Also the following Syrphide, viz.:—Syrphus compositarum, Ver., S. flavi-

frons, Ver., and S. punctulatus, Ver., all new species; together with S. annu-

latus, Zett., 8. barbifrons, Fall., and 8. nigricornis, Ver. (= obscurus, Zett.),

the last three having been found in this country for the first time.

Mr. M‘Lachlan stated that he had been informed by Lord Walsingham

that when on his recent visit to California and Texas he had frequently

noticed dragonflies preyed upon by other large insects whilst flying through

the air. These latter were, no doubt, some species of Asilus; but it was

the first time he had heard of dragonflies being preyed upon by other

insects, as they had hitherto been supposed to be free from such attacks.

Mr. F. Smith remarked that when examining the box of insects sent to

him from Calcutta, by Mr. Rothney, he had come upon a species of Penta-

toma of a dull brown colour. Mr. Rothney stated that whilst seeking

shelter under a tree from the sun, he observed the bark of the tree covered

with hundreds of this species, which were of exactly the same colour as the

bark, and on this account were not readily noticed. . Mr. Smith was not

aware why the insect should require this protection. Mr. Bates suggested

that they might be subject to the attacks of lizards; but Mr. Meldola

thought that it would be useful to them in attacking other insects, which

they were occasionally known to do, although usually phytophagous in their

habits.

Papers read, ée.

Major Parry communicated a paper on the “ Characters of Seven Non-

Mr. Frederick Bates communicated “ Descriptions of New Genera and

Species of Tenebrionide from Australia, New Caledonia and Norfolk

Island.” :

Mr. Albert Miller read the following remarks communicated to him in

a letter from Mr. W. F. Bassett, of Waterbury, Connecticut, U.S. :—

“T found, early in the spring, almost as soon as the buds began to swell,

large numbers of a female Cynips—the species unknown to me—ovi-

positing in these buds. I had seen the same in the two preceding seasons,

but in only a few instances. The insect, standing on the summit of the

bud, thrust the ovipositor down between the bud-scales, but did not in any

ease, so far as I noticed, penetrate the scales. I inferred that the eggs

were laid in or on the embryo leaf. I marked several trees where I found

these female flies, and watched with much interest to see what species, if

any, would be found on them. I found the leaves, when developed, to

contain galls of C. q.-futilis, Osten-Sacken, and with few if any other species

intermixed ; and the abundance of this species was in close agreement with

the number of females ovipositing before the leaves appeared. These galls,

when found at all, are usually very numerous, and on some of these trees

there was hardly a leaf that did not contain from one to eight galls, each of

which would produce from three to five insects. The fly of C. q.-futilis

(found in. both sewes) is much smaller than the species I found ovipositing.

I think that when we come to find out the true history of these dimorphous

and, in one generation, unisexual species, we shall find that those com-

posing the generation of females are generally larger, and perhaps struc-

turally distinct from the bisexual brood. What form of gall these apparently

immediate progenitors of C. q.-futilis may come from I cannot say, though

I still hope to trace them to their gall.

«T repeated last spring the experiment tried several previous seasons,—

that of raising a brood of flies from the galls found in the form of irregular

swellings on the twigs of an oak growing near my residence. I raised an

immense number, all of which were females; and in June I reared still

greater numbers, male and female, from enormously swollen petioles of

leaves of the same tree. These two broods are remarkably alike, so much

so that I could not separate them if mixed. ‘There is, in this instance,

no perceptible difference in the size of the individuals composing the two

broods.

“Tt seems to me to be settled now that most, if not all, our species of

Cynips are double-brooded, and that one of these generations consists of

females only. Besides the two cases I have mentioned, where the connexion

between the two broods is apparently well established, there are so many

one-gendered species that we may reasonably suppose each to be the pro-

genitor of some one of the equally numerous doubled-gendered species, but

whose relationships have not yet been observed. Iam willing to venture the

remark that probably no one-gendered species exists—that those apparently

unisexual species, C. q.-punctata, Bassett, C. q.-spongifica, Osten-Sacken,

and those European species which, though reared in countless numbers,

xvi

have as yet been found only in the female sex, will be found to be double-

brooded species, one of which will be exclusively female and the other male

and female.

“JT have two or three years tried to raise a colony of C. q.-punctata,

Bassett, by placing the large polythalamous galls on uninfected trees just as

the insects were ready to escape. So far I have failed to rear any galls of this

species. Now if these females really reproduce the same kind of gall

I ought to have succeeded, for I colonized several hundred individuals on a

single small tree, and many more on other trees in different seasons. Of

course the inference to be drawn from the failure of my attempt to raise

these galls has no scientific value, but had I succeeded in raising the galls

the fact would have been received as satisfactory proof that these female

flies could produce generation after generation of females without the aid of

the male element.

“JT take the ground that the reproduction of gall-insects without the inter-

vention of the male is limited to a very few, if not even to one generation ;

and that all our unisexual species are dimorphic forms of double-gendered

species. I wish yourself and all others interested in working out the

singular history of this family would give attention to these points.

And may I ask you to inform me if anything has been written within a

year or two that throws any light upon them, as I am aware that my non-

intercourse with the entomologic world for a year or two past has left me

far behind possibly on this very point.

“‘T was able last spring to settle, to my own satisfaction at least, a question

raised by myself in the first article I published on the Cynipidee,—the ques-

tion whether the woolly galls, C. q.-seminator, Harris, and C. q.-operator,

Osten-Sacken, were or were not abnormally developed leaves. I took the

ground that they were, that the eggs were deposited in the oak-bud, that

the sinall seed-like gall was only a modified leaf-stem and blade, and that the

wool was only an enormous development of the pubescence always present on

the young leaves. Mr. B. D. Walsh opposed this idea, and, either in a pub-

lished paper or in a letter to me, denied that the gall had any connexion

whatever with the bud or leaves. Last spring I was so fortunate as to find

two galls of C. q.-seminator in their earliest stage, and was able to watch

them in their development. They are really developed from buds, and are,

as I supposed, only modified leaves. The smooth shining cell or gall is the

petiole of the leaf, and the tuft of long woolly hairs that terminates the cell

is only the enormous development of the leaf’s pubescence.”

Exhibitions, dc.

My. Higgins exhibited a specimen of a remarkable insect recently described

by Mr. F. Moore under the name of Langia zeuzeroides (said to pertain to

the Sphingide). It was from the Himalayas, and had been bred by Major

Buckley from a larva feeding on wild apricot. He also exhibited a female

specimen of Goliathus albosignatus (Kirkii, Westw.), from the Limpopo,

being, as he considered, the only known example of that sex.

Mr. M‘Lachlan exhibited a coloured plate of butterflies from Turkestan.

This he had been requested to show to English entomologists, as a sample

of the manner in which the forthcoming work on the Natural History of

Turkestan is to be illustrated. The entomological collections had been

chiefly made by M. Alexis Fedtschenko during the years 1869—71. The

XVlil

work is to be published in the Russian language, with Latin diagnoses of

the new species.

Mr. Bates alluded to an insect figured in the plate as Colias Nastes, var.

Cocandica. C. Nastes had, hitherto, only been found in Lapland (var. Wer-

dandi) and in Labrador and Arctic America, and it was a striking instance

of the manner in which some species inhabiting the Arctic regions are found

southwards in mountainous districts, though not in the intervening plains.

He mentioned also that Colias Paleeno was found near the snow-line in the

Alps, and in Lapland.

Mr. Miiller said that he felt much interested in the remarks offered by

Mr. Bates, as they confirmed his own conclusions, concerning the very close

connection, or perhaps even identity, between the Arctic and the Alpine

insect-faunas. He referred to one remarkable instance, namely, to the Genus

Parnassius, and in particular to P. Apollo, which occurred in most parts of

Northern Europé and Asia; but which in Central Europe—i.e. in Switzer-

land—was confined to the Alps and the opposite Jurassian range, carefully

avoiding the intervening alluvial plains, which in the glacial period had been

covered by the glaciers of the Rhone, the Neuss, the Rhine, and minor tribu-

taries. He added that if the actual stations of the species were mapped they

would all be found to exist outside, but along the moraines left by the ancient

glaciers; and that the same was the case with Delius and Mnemosyne.

Mr. Albert Miller was desirous of making some inquiry concerning the

literary remains of an entomologist. It was mentioned by Markus Lutz, of

Basle, in his ‘ Moderne Biographien’ (Lichtenstieg, 1826, pp. 39—40), that

Johann Samuel Clemens, a native of Chambéry, in Savoy, was a clergyman

in the Val d’Illies (Lower Valais), and that he was a learned naturalist. He

is said to have formed a library of 8000 volumes, an herbarium, a collection

of minerals and insects of the country; and is reported to have committed

to paper many good observations concerning the Natural History of the

Valais, none of which seem to have been published. He is said to have

died in 1812. Mr. Miller said that he would be thankful to any Italian,

French or Swiss entomologist who might be able to give information con-

cerning the manuscripts of this divine, either by letter to himself or through

any entomological publication.

Mr. Stainton exhibited a cocoon found by Mr. A. H. Swinton in the

crevice of a wall at Kilburn. Its surface was smooth and extremely hard,

and it had an oval opening at one end. Mr. M‘Lachlan considered that it

was an ancient cocoon of Cerura vinula, altered in texture and surface in

consequence of the larva having had to construct it on a wall instead of on

a tree-trunk.

been recently split, showed the occupants in their natural cells. Specimens

of the perfect insects reared from the larvae were also exhibited, consisting of

the following:—Trypoxylon figulus, Smith; Raphiglossa Kumenoides,

Mr. Miiller communicated the following notes on the discovery, by

Dr. Emile Joly, of Toulouse, of a nymph which he announced to belong to

a species of Oligoneuria :—

“ Having for the last fifteen years endeavoured to find the unknown early

conditions of Oligoneuria Rhenana, Imhoff, but so far without success, it is —

a matter of no little consolation to me to be enabled, through the courtesy

of my valued friend Dr. Emile Joly, to announce, on his behalf, to the

Society, his important discovery of the first nymph known in the genus

Oligoneuria, and belonging to the species named by him ‘ Garumnica.’ For

this purpose I translate here Dr. Joly’s communication from the French

MSS., agreeably to his desire. My friend writes, ‘I have the honour of

addressing to the Entomological Society of London two drawings, to my

knowledge entirely unpublished, and representing (fig. a), the upper side,*

Fig. A.

(The above are three times the natural length.)

* This nymph, like the one of Palingenia Roeselii (vide Mém. de la Soc. des

Sci. Nat. de Cherbourg, t. xvi.), with long cilie only on the internal border of the

anterior legs, presents, like the last, above the thorax and in pairs overlying each

other, four corneous sheaths intended to lodge the folded-back (repliées) wings of the

insect up to the moment of its passing to the subimago state. It is therefore not,

as Imhoff supposed, by a kind of division, by a spontaneous fissuring, that the four

wings are formed, which are so easily recognised in the imago state of the insect,

but rather that if sometimes there seem to exist only two wings, it is, as Hagen had

at first deduced theoretically, because there exists a perfect attachment by simple

agglutination of the posterior border of the fore wing to the anterior border of the

hind wing.

XX1-

and (fig. B) the under side of the nymph of a new species of Oligoneuria,

for which I have already proposed the specific name “ Garumnica.”* In

1869, on the very last excursion which I had the opportunity of making in

the bassin of the Garonne at Toulouse, I had the good luck of detecting the

singular metamorphoses of this species. In all probability this nymph is

the first and only one discovered in this genus up to the present time, as

neither Pictet, the founder of the genus (O. anomala), nor Imhoff (O. Rhe-

nana), nor Hagen (O. Rhenana, var. pallida), nor my friend Albert Miller

in his different observations on the habits of O. Rhenana, nor M‘Lachlan

(O. Trimeniana), nor lastly, even the Rey. A. E. Eaton, in his fine and

quite recently published monograph on the Ephemeride, + mention anything

concerning the larval stage (l'état de ver), or, as it is called in England,

“the immature condition of the subaqueous stages of development,” of any

of the species, the names of which I have enumerated. I intend to publish

shortly the complete anatomy of this curious nymph.’”

With regard to the above notes, Mr. M‘Lachlan remarked that it would

be most desirable to obtain further and more minute particulars respecting

Dr. Joly’s observations. The information furnished was very vague, and

no characters were given of the supposed new species.

Mr. Wollaston communticated a paper “ On the Genera of the Cossonide,’

including descriptions of 139 species which had not hitherto been recorded.

The Secretary read the following remarks, communicated to him in a

letter from Mr. Roland Trimen, of Cape Town :—

“IT have lately read with much interest the Rev. R. P. Murray’s notes

‘On some Variations of Neuration observed in certain Papilionide,’t and

desire to offer the following remarks thereon. In cases 1, 2, 3 and 4,

Mr. Murray does not state whether the anastomosing or coalescing nervures

are those of the fore or hind wings; but in the 1st and 2nd, it is clear, from

the mention of Synchloé (Pieris) Mesentina, Cramer, that the fore wings

are intended. In this Pieride, however, the junction of the first subcostal

nervule with the costal nervure of the fore wings is not an aberration but a

constant character of that species, as well as of P. Severina, Cram., and a

few allied species, and (as mentioned by me in Trans. Ent. Soc. 1870,

p- 878) has been noticed by both Wallengren and Wallace.

“T am enabled to supplement case 5, ‘ P. Clodias’ (? Parnassius Clodius,

Mén.), by a very similar and even more remarkable instance in a male

Papilio Merope, Cram., which has just recently come under my notice. As

in Mr. Murray’s description, the subcostal nervules of the hind wing in this

mérines,” No. 1, in t. iv. du Bull. de la Soc. d’Hist. Nat. de Toulouse, avec Planche. !

specimen of Merope are connected by a transverse nervule; but the addi-

tional nervule (instead of being incomplete and confined to the right hind

wing) is found in both hind wings and thoroughly unites the subcostal

nervules. In this manner a perfect addi-

tional cell is formed (see A in figure) imme-

diately adjoining and above the ordinary

discoidal cell, and extending beyond it. The

subcostal nervules are ‘angulated and drawn

together’ by the transverse nervule, quite as

Mr. Murray describes in P. Clodius, and the

additional cell is of the same size and shape in both hind wings. It is

observable that the true discoidal cell is not at all distorted, but of the normal

size and form in both hind wings. ‘This interesting example of P. Merope

was taken by Mr. J. H. Bowker on the Boolo River, a small tributary of

the Tsomo, in Kaffraria Proper.

“T have in another place’ (Trans. Linn. Soc., vol. xxvi. p. 501, note)

commented on the remarkable neuration of the Papilionide, and pointed

out how the presence of more than one cell enclosed by anastomosing

neryures constitutes an indication of affinity to the Heterocerous groups of

Lepidoptera; and this indication acquires additional significance in view of

the interesting facts recorded by Mr. Murray respecting butterflies of this

family, and of the circumstance of the tendency to form additional wing-cells

finding such marked development in the specimen of P. Merope above

described. There can, I think, be little doubt that (as Mr. Murray suggests

in reference to the pre-discoidal cell discovered in some examples of Thais

Polyxena, W. V.) these exceptional cases of neuration are referable to rever-

sion to ancestral characters, and point to a remote community of origin

between the Papilionide and the higher Heterocera.

“Tn my discussion (loc. cit., pp. 501-2) of this question of the position

of the Papilionide, I overlooked Boisduval’s account (Faune Ent. de

Madag., &c., pp. 6 and 113) of the larva of the splendid Urania Rhipheus,

or I should not have quoted Cerura as affording the only other instance

among the Lepidoptera of organs analogous to the Y-shaped tentacle of the

Papilionide caterpillars. Boisduval states particularly (on the authority of

Captain Sganzin, who reared a large number of the Urania) that the larva

of Rhipheus possesses, ‘comme dans les Papilio,’ ‘deux cornes rétractiles,

roses, placées sur le premier anneau,’ adding that it exserts them at will

(‘fait sortir a volonté’). Mr. Wallace, not only in his paper on Malayan

Papilionide (Trans. Linn. Soc., vol. xxv.), but more recently in his valuable

‘Contributions to the Theory of Natural Selection,’ 2nd edit. 1871, has laid

such stress on the possession of the exsertible Y-shaped organ being, as the

exclusive character of Papilionide larve, a sign of the highest development

of the Lepidopterous Order, that the presence of an apparently identical

xXxill

organ in the undoubtedly Heterocerous Urania is a fact most worthy of

special notice.

« PS.—I add a line to say that I have just heard (24th April) that proof

of the species-identity of Papilio Merope and Ps. Cenea, Hippocoon and

Trophonius has been obtained by Mr. Mansel Weale, who has reared them

all from larvee found on Vepris lanceolata. I hope to give full particulars

shortly.”

Mr. Higgins exhibited two bred specimens of Deilephila Euphorbie

(one a remarkable variety), and a Sphinx Pinastri, taken near Harwich

XXVil

in June, 1872, when several specimens of the former were found in the

larva state.

Mr. Champion exhibited a bred specimen of Pachnobia alpina from

Braemar; also Harpalus quadripunctatus, Dej., from Braemar; Aniso-

toma-macropus, Rye, from Claremont; A. pallens, Germ., from Deal;

Liosomus troglodytes, Rye, from Faversham; and L. oblongulus, Boh.,

from Caterham.

Mr. W. C. Boyd exhibited living larve of Brachycentrus subnubilus,

which had been reared from the eggs. They fed upon Conferve, and the

cases constructed by them were clearly quadrangular (though the angles were

not prominent), and very diaphanous, so that the movements of the larve

could be discerned within.

Mr. Bond exhibited fine specimens of Chilo gigantellus from Horning

Fen.

Mr. Vaughan exhibited Pempelia Davisella reared from larvee, feeding in

a web, upon shoots of Ulex.

Mr. Stevens exhibited Leucania L-album and Cerastes erythrocephala,

said to have been taken at Canterbury by Mr. G. Parry. Also Acontia

solaris taken near Dover in 1872, and a curious variety of Arge Galathea

taken in 1871 on the South coast.

Mr. Miller remarked that at a meeting of the Scientific Committee of the

Royal Horticultural Society, on the 12th instant, Dr. Masters had- exhibited

some galls found at Wimbledon on the roots of Deodara. That gentleman

had since submitted to him further specimens of this gall, which he had

found to agree, in external and internal structure, with those of Biorhiza

aptera, Fab., usually occurring on roots of oak. Mr. Miller stated that

he had since bred several specimens of Biorhiza aptera from these Deodara

galls, and that he believed it to be the first instance where a true Cynips

had been known to transfer its attacks from oak to a species of Conifer.

Mr. W. H. Miskin, of Queensland, communicated some remarks on

Mynes Guerini, described by Mr. A. R. Wallace in the ‘ Transactions of

the Entomological Society,’ 1869, p. 77, but which he considered to be

identical with Mynes Geoffroyi, Guer., from the Malayan islands. He

alluded to a singular peculiarity in the economy of the insect, namely, that

the larvae, which were gregarious in their habits, preserved their social

instincts even to their assuming the pupa state—the chrysalides being

found collected together in groups of three or four individuals, united at

the tails.

A paper was read entitled “ Notes on the Habits of Papilio Merope,

Mr. John George Marsh, of 842, Old Kent-road, was balloted for and

elected a Subscriber to the Society.

Exhibitions, éc.

Mr. Bond exhibited a hybrid specimen between Clostera curtula and

C. reclusa, partaking of the characters of both parents.

Mr. Jenner Weir exhibited specimens of a minute Hymenopterous insect

(a species of Psen), which he had observed in large numbers (probably 150)

XX1X

in June last, on a pear-leaf at Lewes. They had congregated together on

the surface of the leaf like a swarm of bees, though it was not apparent

what motive brought them together. |

Mr. Dunning read some portions of a letter which he had received from

Mr. Nottidge, enclosing the EKighth Report of the Canterbury (New Zealand)

Acclimatization Society, and stating that the red clover had been introduced

into the colony, but that they had no humble bees to fertilize the plant.

Also that certain Lepidopterous insects had been accidentally imported into

the islands, but that the corresponding ichneumons were wanted to keep

down their numbers. He would be glad of any suggestions as to the best

mode of introducing both humble bees and ichneumons into the colony, as

might be requisite. It was suggested that by procuring a sufficient number

of humble bees in a dormant condition and keeping them in this state (by

means of ice) during the voyage the result might be attained. Mr. M‘Lachlan

mentioned that he had received a letter from Capt. Hutton from the same

colony, stating that indigenous Aphides did not, apparently, exist there, but

imported species were becoming very destructive, and he asked if it would

be possible to introduce Chrysopa.

Papers read, &c.

Mr. Baly communicated a paper on the Phytophagous Coleoptera of Japan,

being a continuation of that contained in the ‘ Transactions’ of the Society

for 1873, p. 69.

Mr. Bates contributed a paper on the Longicorn beetles recently brought

home by Mr. Thomas Belt from Chontales, Nicaragua, being supple-

mentary to that published in the ‘Transactions of the Entomological

Society’ for 1872, p. 163. The additional species amounted to thirty-

seven, which, with those enumerated in the previous paper, brought up

the total number to 309. Mr. Bates remarked that a work by Mr. Belt

would shortly be ‘published on Nicaragua, which he believed would be of

much interest to entomologists.

Mr. W. H. Miskin, of Queensland, communicated criticisms on a Catalogue

of the described species of Diurnal Lepidoptera of Australia, by Mr. George

Masters, of the Sydney Museum.

A fourth portion of the ‘Catalogue of British Insects,’ now being pub-

lished by the Society, was on the table. It contained the Hiymeeapters

(Oxyura), compiled by the Rev. T. A. Marshall, M.A.

A Prospectus was on the table of a Scientific Societies Club, whicl it was

proposed to establish in the neighbourhood of Burlington House.

Mr. Meldola exhibited some photographs of minute insects taken with the

camera obscura and microscope.

Mr. M‘Lachlan called attention to a paper in the last part of the

‘Annales de la Société Entomologique de France,’ by M. Bar and Dr.

Laboulbéne, on a species of the Bombycide closely related to the tiger-

moths, described and figured by M. Bar as Palustra Laboulbenei, and of

very extraordinary habits, the larva being aquatic, living in the canals of

the sugar plantations in Cayenne, and feeding upon an aquatic plant. The

hairy larva had all the form usual for the group, and breathed by means of

small spiracles—a supply of air being apparently entangled in its hairs.

The cocoons were joined together in little masses floating on the surface of

the water.

Mr. Butler remarked on a paper by Mr. J. V. Riley, in the ‘ Journal of

the S. Louis Academy of Sciences,’ in which he alluded to Apatura Lycaon,

Fab., and A. Herse, Fab., as distinct species: but which he (Mr. Butler)

believed to be closely allied to, if not identical with, Apatura Alicia,

Edwards.

Mr. M‘Lachlan read a letter that he had received from M. Eruest Olivier,

stating that the collection of insects formed by his grandfather had been

purchased some years after his death by MM. Chevrolat and Jousselin.

A great part of the collection had been suffered to fall into decay; but ,

recently a portion, comprising the Curculionids, Heteromera, Lamellicornes,

Sternoxi, Chrysomelide, Clavicornes and Hydrocantharide had come into

his possession, and he would be happy to show them to any English

entomologist who might desire to examine any of the numerous types.

Unfortunately the Carabide and Longicornes were almost entirely lost.

ANNUAL MEETING,

Prof. Wrestwoop, M.A., F.L.S., President, in the chair.

‘An Abstract of the Treasurer’s Accounts for 1873 was read by Mr.

Jenner Weir, one of the Auditors, showing a Balance of £150 10s. 3d. in

The Secretary read the following—

Report of the Council for 1873.

In accordance with the Bye-Laws, the Council presents to the Society

the following Report :—

During the year, eleven Members or Subscribers have been elected,

whilst sixteen have been removed from the list by death or otherwise: the

loss in our numbers is therefore five.

The volume of ‘ Transactions’ for 1873 will contain eighteen memoirs,

extending to 657 pages, exclusive of Proceedings, and illustrated by five

XXXli

plates, one entirely and another partially coloured. The Society is indebted

to Major Parry for the drawing and engraving of the plate illustrating his

paper ou Lucanoid Coleoptera. Six of the above papers, comprising

230 pages (one-third of the volume), are descriptive of the Coleoptera of the —

Japanese Archipelago, from the collections of Mr. George Lewis.

The statement of Receipts and Payments shows the following result :—

Thus the expenditure has exceeded the receipts by about £13, which will

be readily accounted for by the increased size of the volume of ‘ Trans-

actions,’ being the largest yet published by the Society in any one year.

And, in addition to this, the Council have issued a fourth part of the

‘General Catalogue of Insects Indigenous to the British Islands,’ com-

prising the Hymenopterous group, Oxyura, by the Rev. T. A. Marshall.

The cash balance of £15 6s. 1d. at the beginning of the year is reduced to

£2 1s. 3d.

The necessity of increased accommodation for the Library, which has far

outgrown that at present provided for it, as well as for a room for the

meetings of the Society, has now become a matter for the anxious con-

sideration of the Council. It is true that the Linnean Society has kindly

renewed the permission for the members to meet in these rooms during the

present session, but at the end of that time accommodation must be found

elsewhere. An application has been forwarded to the Chief Commissioner

of Works, with a view to ascertain whether the Society could be allowed to

occupy apartments in Burlington House, and the Council have notified

their intention of giving up the occupancy of their present rooms at

12, Bedford Row, at Midsummer next. It is hoped that before that time

the question whether the Government will provide accommodation may be

favourably decided; otherwise it will be for the consideration of the Council

as to what further steps may be necessary.

26th January, 1874.

The following gentlemen were elected Members of Council for 1874 :—

Sir Sidney Smith Saunders, Messrs. W. C. Boyd, Dunning, Grut, Meldola,

Moore, M‘Lachlan, F. Smith, Stainton, Stevens, Verrall, Jenner Weir and

Professor Westwood.

The President read the following Address :—

XXXill

THE PRESIDENT’S ADDRESS.

GENTLEMEN,

In addressing you on the present occasion I must be

allowed, in the first place, to express the great regret which

I have experienced, during the past year, from having been

prevented by severe illness from attending several of the meetings

of the Society. Those only who, like myself, have scarcely ever

failed being present at our reunions since the first establishment

of the Society, can fully appreciate such a forced absence from

them; and I greatly fear that the same cause will continue to

operate against my frequent presence on such occasions.

The Annual Report presented to you by the Council, and just

read, will have made you acquainted with the satisfactory state of

the Society, both in a financial and scientific point of view; and

I cannot leave this chair without expressing the gratifying con-

viction which I entertain that our Society has become firmly

established, and is recognized as one of the necessary conduits of

knowledge. Our publications and the proceedings at our meetings

have taught the world that Entomologists are somewhat more

than butterfly catchers, and that the vast tribes of animals which

constitute the materials of our study possess claims, both econo-

mical and scientific, to the attention not only of the professed

naturalist, but also of the general public.

Although we have not had occasion, so far as I have learned,

to mourn the loss of any of our more prominent fellow-workers

in this country, several eminent naturalists and entomologists

have passed away- lately whose memory claims a short notice

from me.

-Dr. Kaup, of Darmstadt, was a distinguished Paleontologist,

but he had made his name famous amongst us by an admirable

memoir on the difficult group of Passalides, and by his deserip-

tion of many new species of the curious tribe of Phasmide.

George Ritter von Frauenfeld was one of the naturalists of the

celebrated Novara Expedition of the Austrian Government; he

XXXIV

was a genuine lover of Nature in a wide extent, and was espe-

cially attached to the investigation of the habits of insects.

I recollect on one of his visits to England he came to Oxford at

a time when I happened to be absent for several hours; and on

my return, I found that, instead of rambling over our fine old

colleges and other academical establishments, he had taken a walk

into the adjoining lanes, and had found some galls and mined

leaves which greatly interested him.

Robert M‘Andrew, F.R.S., died on the 22nd of June last,

at the age of seventy-two years. Although especially devoted to

Conchology, he had extensively collected the Crustacea during

his various dredging expeditions.

Albany Hancock, who died on the 26th of October last, was

also much attached to the British Crustacea, although his

admirable researches were chiefly confined to other invertebrate

groups.

We have also to regret the deaths of Dr. Louis J. R. Agassiz and

Mr. Edward Blyth, both naturalists of distinguished eminence, but

not especially entomologists, although the latter gentleman, pre-

vious to his residence in India, had made insects a portion of his

general zoological studies. From the ‘Atheneum’ of Saturday

last (January 24th) we learn that a few days before his death

Prof. Agassiz completed a paper “‘ On Evolution and Permanence

of Type.” This has been printed in the ‘American Monthly,’

and is well deserving attention: the author’s views with regard to

the Evolution hypothesis being well known, as especially stated

in his ‘Methods of Study in Natural History;’ his ‘Nomenclator

Zoologicus,’ and his bibliographical work published by the Ray

Society, have been of great service to entomologists.

With great regret, we learn from this evening’s newspapers

that apparently reliable intelligence has been received of the death

of Dr. Livingstone. ‘The observations on Natural History, espe-

cially on the venomous 'T'setse fly, published in his ‘ Missionary

Travels in South Africa,’ sufficiently show the interest which he

took in Entomology, as do also several interesting insects which

he had collected (including the singular Phyllomorpha Living-

stonii, described by me in our Transactions), and which are now

preserved in the Oxford Museum, to which he presented them

during his visit to Dr. Daubeny (shortly before his departure to

Africa), on which occasion he especially requested me to inform

XXXV

him of the entomological subjects most worthy of his attention

during his intended travels.

During the progress of this sheet through the press, we have

received from Paris the sad news of the death of Félix-Edouard

Guérin-Méneville, one of the most accomplished entomologists,

a most admirable artist, and one of our foreign honorary members.

Born in 1799, for fifty years he unceasingly contributed to the

progress of our Science in all its various departments, his first

memoir having appeared in 1828. His great work, the ‘Icono-

graphie du Régne Animal,’ occupied fifteen years in its publica-

tion; and his ‘Magasin de Zoologie,’ commenced in 188], still

survives, being now published by M. E. Deyrolle.

Monsieur Brullé, Professor of Zoology at Dijon, was long

attached to the Jardin des Plantes in Paris, and is well known

for his many memoirs, published chiefly in the ‘ Annales’ of the

French Entomological Society, and especially for his fine work

on the Insects of the Morea.

In last year’s Address I informed you of the progress in

Natural Science which had been made at Oxford during the few

preceding years, and have now to add that, in consequence of the

Report issued by the Royal Commission on Scientific Education,

further steps have been taken in the same direction; several of

the more recently appointed professors of different branches of

Natural Science have been elected full Fellows of several of the

Colleges, several readers and teachers of the same subjects have

been appointed by different Colleges, and an official enquiry has

been set on foot as to the steps which appear desirable to adopt

for further advancing the progress of these sciences. My reply to

this inquiry (addressed to the various Professors) bears so much

upon our especial subject that I consider it advisable to make

you acquainted with it.

“ To the Very Reverend the Vice-Chancellor.

** Oxford, 27 November, 1878.

‘Sir,

‘Tn reply to the circular recently addressed to me concerning the

Professorship of Zoology, I do not consider that the study of that branch of

Biology can be properly pursued in the present constitution and distribution

of the Professorships of Oxford.

“The development of Physical and especially Biological Science has

been most rapid within the last twenty years, and the proper teaching of

XXXVi1

Zoology requires—I1st. A knowledge of all the leading types of animals,

including their general structure, habits, geographical distribution, trans-

formations, &c.; 2nd. Comparative Anatomy, especially of the Vertebrated

groups; 8rd. Paleontology, as no modern work on Zoological Classification

can be considered as complete in which the extinct species are uot intro-

duced into their proper situations in the zoological series; 4th. It has been

urged, I think injudiciously, that the minute anatomy of the tissues,

cells, &c., of animals (Histology) ought also to form a portion of the

Zoological Professor’s teaching.

“Mr. Hope’s deed of donation and foundation of the Hope Professorship

of Zoology directs that the duties of his Professor should be especially

directed to the articulated animals; and in the Syllabus of Studies of the

great Continental Universities, printed in the Report of the University

Commission, it will be seen that a separate Professorship is assigned to this

division of the Animal Kingdom, Dr. Gerstaecker at Berlin and M. Emile

Blanchard at Paris being the Entomological Professors.

“The Keepership of the Hope Collections throughout the Museum was

also imposed on the Hope Professor, and the enormous extent of his

Collections (the Entomological portion as a whole being, in my opinion,

only surpassed by the National Museums of London, Paris and Berlin)

will always absorb a very large portion of the Professor’s time, independent

of professorial teaching.

“Tt would therefore, in my opinion, be desirable that an Assistant

Professor of Zoology should be appointed, as well as one of Comparative

Anatomy, with which Histology might be temporarily associated, if it

should be thought desirable to detach it from Physiology. A Readership in

Paleontology seems also advisable.

“T cannot conclude this letter without mentioning another subject which

has long forced itself on my attention, namely the want of a Professor or

Reader in Natural Theology, whose duty it should be to counteract the

atheistical demoralization resulting from the unlimited teaching of Dar-

winism, in which Design in Creation, and even Creation itself, are openly

or virtually denied or ignored.

“Tam, Very Reverend Sir,

“ Yours, &c.,

“J. O. WEstTwoop.”

The attempt which is now being extensively made to introduce

the study of Natural Science, and especially Natural History,

into the principal great schools throughout the country has been

proved to work in a satisfactory manner at Marlborough College,

and I have now before me the seventeenth half-yearly Report of

the Natural History Society of that establishment, which was

XXXVI

founded in April, 1864. In this goodly part we find it stated

that the entomological collection belonging to the Society has

been considerably increased by donations, including one of

Deilephila Livornica, “ which was undoubtedly caught near Marl-

borough,” whilst “a complete list of all the Lepidoptera known to

occur within our district” extends to twenty-four pages, closely

printed.

On this subject I may refer with much satisfaction to a

pamphlet published by Everard F. Im Thurn, of Exeter College,

Oxford, entitled ‘Notes on a School Museum,’ dated January 21,

1873, being an address to the Natural History Society of the

above-mentioned College.

The establishment of new Societies of Entomologists, not only

abroad but in various parts of our own country, is a very gratifying

proof of the unfading interest taken in the subject in many new

centres of scientific pursuits.

The Rules of Zoological Nomenclature have formed the subject

of a pamphlet published by Dr. Sharp, in November last, with

the title, ‘ The Object and Method of Zoological Nomenclature,’

in which the author laments the constant changes in the names

of even the most common insects, and the consequent increased

disgust with which the science is regarded. Dr. Sharp insists

that the name of an insect ought to be unalterable, and that it

ought to serve only for nomenclature and not for classificational

purposes; and he proposes to carry this out by having three

names for each species, namely, the two names by which it was

first described, and a third name, in a separate column, being that

of the modern genus to which it is from time to time assigned,

thus—

Scarabeeus stercorarius, Linn. Geotrupes, Jek.

Scarabeeus sabulosus, Linn. Trox, Harold,

Silpha scabra, Linn. Trox, Harold ;

the first two names to remain unchangeable, and the last to be

supposed liable to change according to the views of any future

writer. I can scarcely conceive that any one will feel disposed to

adopt these views of Dr. Sharp, and yet they have been partially

carried out by many writers. The great difficulty in the matter

consists in the infinite number of the species of insects, the great

majority of which are unknown to the world at large. The case

XXXVI

is, however, quite different with creatures of popular interest.

Thus, in writing a popular work on Zoology, or in casually men-

tioning a well-known animal in a work of still more general

character, we should employ only a single name, as, for instance,

the horse, the giraffe, or the peacock, thus adopting the mono-

nymic method; but if the object were less generally known, we

should speak of the death’s-head moth or the peacock butterfly,

which, if we wished to apply the scientific names, we should call

Sphinx Atropos or Papilio Io, one of the two names being un-

questionably a classificational one; but if we speak of these two

insects to a Lepidopterist we must be still more precise, and call

them Acherontia Atropos and Vanessa Io; and this triple set of

names, Sphinx (Acherontia) Atropos, is precisely what has been

long adopted by many writers. “It is,’ as was well observed by

the late Robert Brown, “ analogous to the method followed by the

Romans in the construction of the names of persons, by which

not only the original family, but the particular branch of that

family to which the individual belonged, was expressed. Thus

the generic name corresponds with the nomen (Cornelius), the

name of the section with the cognomen (Scipio), and that of the

species with the prenomen (Publius).”

Under the title ‘On the Origin and Metamorphoses of In-

sects,’ Sir John Lubbock has published a volume containing a

very carefully compiled and arranged view of the different kinds

of transformations undergone by insects from their earliest em-

bryonic state to their adult form, illustrated by many figures,

with a view to tracing the original type of form from which all

the different variations have been derived, and which is assumed

to be found in the genus Campodea, a minute animal allied to

the Lepismide, first described by myself in the Transactions of

our Society. Sir John Lubbock sums up his views thus :—“ It

seems to me evident that while the form of any given larva

depends to a certain extent on the group of insects to which it

belongs, it is also greatly influenced by the external conditions to

which it is subjected; that it is a function of the life which the

larva leads and of the group to which it belongs.’ No one,

I think, can object to the first of the above propositions. Whilst

admiring the excellent manner in which Sir John Lubbock, like

Mr. Darwin, has worked out his facts, I however, for one, cannot

adopt an opinion that the form of the larva of any given species

XXXIX

of insect was modified by existing circumstances, but that, on the

contrary, it was expressly created in a form most fitted for per-

forming its allotted task in the great work of the Creation. In

like manner, I am unable to adopt the theory of the gradual

evolution of the varied forms of larva life from a single proto-

type —an opinion as diflicult, however, to disprove as it is

impossible to prove.

I may here call attention to a Teleological memoir by the Rev.

T. R. Stebbing in the ‘ Quarterly Journal of Science.’

During the past year two very important collections have been -

dispersed ; that of Mr. Thomas Norris, of Redvales, near Man-

chester, had been formed at unlimited expense, and contained

-many very fine and rare insects, amongst which was the Lamia

Norrisii, figured and described by myself in the Transactions of

our Society. This grand and still unique insect has passed into

the collection of Count Mniszech, of Paris. The other collection,

that of Mr. W. Wilson Saunders, was far more important and widely

known, and was especially valuable as containing the greater

portion of the species collected by Mr. Wallace in the Malayan

Archipelago. By the liberality of Mrs. Hope, the Orthoptera and

Heterocerous Lepidoptera (containing the whole of the types

described by Mr. Walker in the Proceedings of the Linnean

Society) have been added to the Hopeian Collections at Oxford.

The constant liberality and kindness shown by Mr. Saunders on

all occasions, both to the Entomological Society and its individual

members, cannot but inspire great regret at the necessity for the

dispersion of his noble collection.

An interesting memoir on the organ of the trachee in various

aquatic insects, especially the Perlide, by Herr Gerstaecker, is

given in the ‘ Sitzungs-Bericht’ of the Natural History Society of

Berlin of the 2ist October last. The remarkable genus Pteron-

arcys of Newman has especially led to these remarks by Dr.

Gerstaecker, which possess much interest in connection with the

question of the real homologies of the abnormal appendages of

several other insects ; and here I may refer to the very interesting

genus Scolopendrella, which has on the under side of each seg-

ment a pair of appendages closely resembling those of the Lepis-

mide,—“ a fact,” as Sir John Lubbock shrewdly remarks, “ which

suggests doubts whether the subabdominal appendages of that

group really represent the legs of Myriapoda.’—Mon. Thysan.

p: 07.

The accounts which have from time to time been published of

the progress of the exploring vessel ‘ Challenger’ have made us

acquainted with the great success which has so far attended

the expedition. Several interesting articles have appeared in

‘Nature,’ giving a detailed account of its proceedings, in which

we find accounts of some very remarkable Crustacea, one of

which, taken at a very great depth, exhibits a considerable

resemblance to the fossil genus Eryon. Another very curious

form, being the largest Amphipod hitherto discovered, has fur-

nished the subject of a memoir transmitted to the Royal Society.

I may, however, remark that this animal was long ago described

and figured by Guérin-Méneville, under the name of Cystosoma,

and that the type specimen was obtained by me from its describer, .

and is preserved in the Hopeian Collection at Oxford.

Mr. Charles V. Riley, the State Entomologist of Missouri, has

issued his ‘ Fifth Annual Report on the Noxious, Beneficial and

other Insects’ of that State GUefferson City, 1873, pp. 1—130).

I have not yet seen this volume, but it contains an article on

stinging larve, of which Mr. Riley is acquainted with fifteen

distinct American species possessing urticating powers, which in

every instance are exerted mechanically, and not produced from

actual poison. Another chapter contains a series of instructions

to young entomologists on the modes of collecting and preserving

insects.

The agency of insects in the impregnation of flowers is a sub-

ject of growing interest. A series of papers on this subject has

recently appeared in the pages of ‘ Nature.’

Mr. Riley has also, during the past year, made us acquainted

with the interesting circumstances attending the impregnation of

the flowers of the genus Yucca by a small moth of a very

remarkable structure, expressly fitted for the purpose, and without

the aid of which the plant could not have been perpetuated.

The subject of the injurious attacks of the Phylloxera upon

vines continues to attract the attention of many observers in

France, and has been repeatedly brought under the notice of the

French Academie des Sciences as well as the Entomological

Society of France during the past year.

A memoir by 8. E. Peal, Esq., published during the last year

at Calcutta (reprinted from the ‘Journal of the Agricultural and

Horticultural Society of India,’ vol. iv.), with seven plates, has

xli

made us acquainted with a new and very destructive enemy to the

tea-plant in Assam. It is a Heteropterous insect, belonging to.

the family Capsidee, and remarkable for having a slender, erect

horn arising from the scutellum: it is similar in its operations to

the Aphides, but is very active, thus resembling the species of

field-bug which in this country is very injurious to the blooms of

_chrysanthemums in the autumn, by thrusting its proboscis into

the young flowers and leaflets.

An admirable volume, on the ‘Natural History of the Grain-

storing Ants and the Trap-door Spiders of the Northern shores

of the Mediterranean,’ has been published by Mr. Moggridge,

who has kindly forwarded to the Oxford Museum a series of

specimens of the nests of the different species of spiders observed

by him.

Mr. Belt, who has contributed so much to our knowledge of

the insects of Nicaragua, has recently published his observa-

tions on the Natural History of that country, in a volume

entitled ‘The Naturalist in Nicaragua: a Narrative of a Resi-

dence at the Gold Mines of Chontales ; Journeys in the Savannahs

and Forests, with Observations on Animals and Plants, in refer-

ence to the Theory of Evolution of Living Forms’ (8vo. London,

Murray, 1874). This title will sufficiently show the bias of the

mind of the writer, whose observations on the many instances of

protective imitation which he met with are full of interest.

The account of the voyage of the ‘ Curacoa,’ by Mr. Brenchley,

contains descriptions of various new Lepidoptera by Mr. F. Smith,

and of some new Lepidoptera by Mr. Butler.

The larval forms of several interesting genera of Coleoptera,

namely, Elmis, Psephenus, Hald. (Kurypalpus, Leconte, Fluvi-

cola, De Kay), Helodes and Cyphon, have been carefully elaborated

by Dr. Rolph (Wiegmann, Archiv. f. Naturg. 40th Jahrg. lst Heft,

1874), and are illustrated by a very full plate.

We have also to notice an admirable memoir, by Dr. Hagen, on

all the known larvee of various species of Ascalaphi and Myrme-

leons, with additions by Mr. M‘Lachlan.

It is with much regret that I learn that the excellent ‘ Entomo-

logist’s Annual,’ which Mr. Stainton has with great liberality

continued to publish for many years, is to be discontinued after

the present year. I trust some plan may be adopted for supplying

its place, and publishing summaries of the new additions to our

: |

Fauna, similar to the lists which M. Deyrolle publishes from time

to time in his ‘Petites Nouvelles.’ Surely such an annual or

half-yearly summary would not be out of place in our own

Transactions, or in the pages of the ‘Entomologist’s Monthly

Magazine.’ For many years I regularly posted up our additions,

in my copy of Stephens’ Catalogue, and can testify to the great

benefit of such summaries.

The vast number of short memoirs published upon restricted

groups or species, in the Transactions of the various Entomolo-

gical Societies and in the many Zoological or Entomological

periodicals, renders it impossible for me to give, in an address

like the present, more than a sketch of the most important ones

which have appeared during the past year. It is, however, to me

a source of increasing regret that the number of entomologists,

who devote their attention to the whole subject, is becoming

gradually smaller, whilst specialists, whose general views of the

After an interval of delay we again welcome the appearance of a

new part of the Transactions of the American Entomological

Society (vol. iv. number 4, completing the volume), containing

papers—by Mr. Aug. R. Grote, “On North American Noctuide ;”

Dr. Horne, ‘“‘On the Bruchide of the United States” (fifty-one

species, more than half of which are new); Mr. W. H. Edwards,

’ “On Six new Butterflies found within the United States Mix.

G. R. Crotch (who has accepted a situation in the Museum of

Cambridge, U.S.), “A Synopsis of the Erotylide of Boreal

America,” “A Synopsis of the Endomychide of the United

States,” “A Revision of the Coccinellide of the United States,”

and “A Revision of the Dytiscide of the United States ;”* and

Mr. Grote, “A Description of a New Species of Tortrix,” and

““A Revision of the Lepidopterous Articles, published by himself

and the lamented Mr. Coleman T. Robinson in former volumes

of the Transactions.”

I have the pleasure on the present occasion to offer to the

Society the first part of my ‘Thesaurus Entomologicus Oxoniensis’

* Mr. Crotch notices the interesting fact that Dytiscus lapponicus, the most

Northern European species, does not “ pass over” to North America, as well as the

prevalence of smooth females in the same genus; “in England, of six species, only

one has a smooth female, and in America only three species have sulcate females,

and those haye also smooth forms.”

(a number of copies of which have been in the publisher’s hands

for the last two months). The work is to be completed in four

parts, with forty plates.

Dr. Barrande still continues his “ Researches on the Silurian

Fossils of the Centre of Bohemia,” and has discovered that,

whilst in the Cambrian formation not more than twenty-eight

animals have been discovered, in the Primordial Silurian system

not fewer than three hundred and sixty-six have been found, of

which two hundred and fifty-two are species of Trilobites, ten of

Ostracoda, and only two of other Crustacea, distributed in that

system of rocks, as follows :—

An important memoir, by G. O. Sars, published in the Trans-

actions of the Royal Swedish Academy (Kongl. Svenska Vetensk.

Akad. Handl. vol. ix.), has only recently reached me. It is

devoted to the species of the very interesting Crustaceous group,

Cumacee, allied to the Myside, a group which has attracted the

attention of some of the most learned of recent Crustaceologists,

who have greatly differed in their opinions of the homologies of

the parts of the mouth and anterior pairs of legs; thus the organs

which Kroyer and Spence Bate regard as the first, second and

third pairs of true legs, were considered by Goodsir as the second,

third and fourth pairs of legs, by Van Beneden as the second and

third pairs of gnathopods and first pair of legs, and by Anton

Dohrn as the second pair of gnathopods and the first and second —

pairs of legs. By Sars, the three short terminal pairs of thoracic

xliv

appendages are considered as the third, fourth and fifth pairs of |

legs, the two preceding pairs of elongated bifid organs being his —

first and second pairs of legs. The anatomy of the group, as well

as the sexual differences, are admirably made out and illustrated

in a series of twenty elaborate 4to plates. In the genus Diastylis,

Say (Cuma, Kroyer; Alauna, Goodsir), the author has added six

species to the thirteen already described by previous writers; to

the genus Leucon, one new species is added to the five already

known; and to the genus Eudorella, Norman (Eudora, Sp. Bate),

three are added to the four previously described.

We are glad to welcome a new English worker in the Crustacea,

the Rev. Thomas R. R. Stebbing having published the description

of a new Spheromid from Australia, and two new species of

Arcturus from South Africa, in the ‘Annals of Natural History’

for August last. It is to be hoped that this gentleman, from

his residence on our South coast, may be able to contribute

to our knowledge of the small but much neglected species of

Crustacea.

We are indebted to the Rey. O. P. Cambridge for his unwearied

labours in making us acquainted with the species of spiders

(especially the exotic ones). During the past year he has

described a number of new and very curious species from Ceylon,

forwarded by Mr. Thwaites, and from St. Helena, captured by

Mr. Melliss, in the Proceedings of the Zoological Society, and

various new European species in the Journal of the Linnean

Society.

Dr. Koch’s work, ‘Die Arachniden Australiens,’ has now

reached the ninth Lieferung, 4to, Nuremberg, 1873. The figures

are, it is to be regretted, by no means sufficiently characteristic.

We are indebted to Mr. A. G. Butler for a series of articles on

various interesting, although much neglected, groups of wingless

insects, namely, the Myriopodous Glomeride, Zephronia, and

Spherotherium; the Arachnidous Gasteracantha, and Achro-

soma; and the remarkable genera Phrynus, Gonyleptes, Galeodes,

and Thelyphonus: these have been published in our own Trans-

actions, in the Proceedings of the Zoological Society, and in the

Annals of Natural History. The systematic arrangement and

morphology, with especial reference to the structure of the

mouth-organs and legs of the Phalangiide, have formed the

subject of an elaborate memoir by William Sorensen, published

xlv

in the eighth volume of the third series of the ‘ Naturhistorisk

Tidsskrift’ for 1873. To the old genera Gonyleptes, Opilio,

and 'Trogulus, are added three new genera, Anelasma, Amopaum,

and Dicranolasma.

The very remarkable structure and singular sexual differences

in one of the parasitic Acaride, at various stages of its existence,

have been described and admirably figured in great detail, by

Dr. Ehlers, of Erlangen, in ‘Siebold und Kolliker Zeitschr. f.

Wissensch.” (Zool. vol. xxiii.) The species belong to the Sar-

coptide, and are named Dermatoryctes mutans and fossor.

The most important entomological work which has appeared

during the past year is Sir John Lubbock’s ‘ Monograph of the

Collembola and Thysanura,’ published by the Ray Society. The

latter of these two terms is confined to the Lepismide, whilst the

Poduride are regarded as of sufficient rank to be considered as a

distinct order, ‘‘more nearly allied to the Insecta than to the

Crustacea or Arachnida, although they cannot in the strictest

sense be regarded as true insects,” thus negativing their relation

with the Orthoptera and Neuroptera.* The structure of the

mouth of the Podurids (Collembola) is carefully examined (as

indeed it had already been in the author's four memoirs, published

in the Transactions of the Linnean Society), from which the

author assumes that their cibarian characters are intermediate

between those of the Mandibulata and Haustellata. The volume

is divisible into two portions: an Introduction of one hundred

pages, containing a review of the previous literature of the group ;t

the classification and general description of the animals composing

the two groups; and an enquiry into “The importance of the

Collembola and Thysanura in relation to the Evolution of the

Insecta.” These remarks, extending to fifteen pages, will be read

with great interest, especially by believers in the Darwinian

theory, which I need hardly say I am not able to adopt. The

second portion of the work, extending to one hundred and fifty

pages, contains the description and technical characters of the

* Sir John Lubbock’s views of their relations with the Myriapoda and Arachnida

are rendered doubtful by a strange typographical blunder in p. 38.

+ The complaint that only two British species of Collembola had been casually

mentioned in English works, namely, Podura plumbea and Smynthius fuscus, in

Samouelle’s Compendium, might have been lessened, had the author been aware of

my articles on several species in the ‘ Gardener’s Chronicle,’

xlvi

genera and species,* with an essay on the scales of these animals,

by Joseph Beck, the microscopist. The work is illustrated with

not fewer than seventy-seven plates. I trust I may here be

allowed to express my admiration of the zeal and skill which has

enabled a gentleman—occupied as the author is as a London

banker of the first rank, a member of parliament, and a profound

archeologist—to produce such a book as the one under notice,

upon a group of small and obscure animals, hitherto almost

entirely neglected by our English entomologists.

The structure of the mouth of the Poduride, notwithstanding

the researches both of Sir John Lubbock and Dr. Meinert of

Copenhagen, still requires investigation, for although the intimate

relation of these insects with the Lepismidz (which have the

mouth formed on the true type of the mandibulated insects, that

is, with one pair of mandibles and one pair of maxille) is clearly

shown by the structure of the mandibles; yet the Poduride are

described by Sir John Lubbock as possessing a second pair of

maxillz, which would indicate an additional head-segment, and

would, as it seems to me, remove the Poduride from the great

group of insects with a single pair of maxille, approximating

them to those Articulata which have several pairs of under-jaws.

Dr. Meinert’s opinion, that this second pair of foot-jaws are

maxillary palpi, obviates this great difficulty.

The great additions to our knowledge of the Coleoptera of

Japan, afforded by the collection made by Mr. Lewis, have formed

the subjects of various communications made to our Society by

different members who have especially studied the different

families.

The indefatigable veteran M. Mulsant has given us a new and

enlarged edition, in the form of a thick 8vo volume, of his work

upon the Lamellicorn beetles of France.

Mr. Frederick Bates has published various memoirs on new

genera and species of Heteromerous beetles; whilst his brother,

Mr. H. W. Bates, has continued his memoirs on various species

of Longicorn beetles.

Dr. Mohnike has given us a revision of the Cetoniide of the

Philippine Islands in ‘ Wiegmann’s Archives’ for the past year.

* T notice that the Podura hyperborea of Bohemann is twice inserted as a Podura

and an Achorutes: also that Savigny’s admirable figures in the great work on Egypt,

and Nicolet’s in Gay’s work on Chili, have been overlooked by Sir J. Lubbock.

A memoir “On the Genera of Cossonide,” by T. Vernon

Wollaston, M.A., F.L.S., has appeared in our Transactions, and

is another example of the minute care which its author bestows

upon every group which he takes in hand. The number of

genera here elaborated amounts to one hundred and twenty-two.

I cannot, however, perceive the advantage of giving the generic

tabulation, the generic characters, the detailed observations on

the genera, and the descriptions of the species contained in these

genera, in four different portions of the memoir, thereby entailing

so much extra trouble in bringing all that relates to each genus

under one point of view.

Under the title ‘HEndomycici recitati,’ the Rev. H. S. Gorham

has published a catalogue of the family Endomychide (EKumor-

phide), with descriptions of thirty-seven new species, making a

total of three hundred and two described species. The group is

divided into the following so-called families :—

1 Eumorphide. 6. Endomycide.

2. Corynomalide. 7. Leiestide.

3. Lycoperdinide. 8. Paussdideide.

4. Hpipocidee. ~ 9. Myceteide.

5. Palzeomorphide.

Seven of these groups are named, as usual, after the leading genus

in each ; and it is to be regretted that this uniformity was not main-

tained throughout, since the eighth is named from a resemblance

between the antenne of its only genus Trochoideus and those of

some of the Pausside, and the fifth from an idea entertained by

the author that the Stenotarsi are the most ancient of the insects

contained in the entire group. I protest against any such vague

notions being concentrated into family or other names. It would

also have added greatly to the utility of the work if the author

had given the usual references to the works where the different

species in his Catalogue had been described. How, for instance,

is the student to trace out of the multitudinous writings of

Mulsant where the description of Polymus, Muls., nigricornis,

Muls., is to be found? We should not forget that whilst, Ars

(entomologica) long(issum)a, vita brevis est.

The steady investigation of the difficult and very numerous

species of dragonflies, by the Baron EKdm. de Selys-Longchamps,

has brought up»our knowledge of the section Gomphines to two

xl viii

hundred species, many additions being enumerated and described

in “ Troisiémes Additions au Synopsis des Gomphines,” in the

Bulletin of the Royal Academy of Belgium, June, 1873, and

“ Appendices aux Troisiémes Additions,’ November, 1873, the

number being swelled by various new species in the Museums of -

London and Oxford, recently visited by the author.

Dr. Stal, of Stockholm, continues his laborious researches on

the Orthoptera, by the publication of a ‘ Recensio Orthopterorum :

Revue Critique des Orthoptéres décrits par Linné, De Geer et

Thunberg’ (Part 1, 8vo, pp. 154). The first fascicle is devoted

to the family of the true locusts (Locustide of English authors,

Acridiodea of Burmeister), and which are divided into the families

Proscopide, Mastacide, Phymatide, Pamphagide, Acridiide,

LTruxalide, Gidipodidee, Pneumoride, Chorcetypide, Ccelopter-

nide and Tettigide. A great number of new genera are esta-

blished, to which are ascribed not only the species described by

the three Swedish authors named in the title, but also those of

more recent writers. ‘The recognition of the former species, in

consequence of the typical individuals being still preserved in the

Museums of Stockholm and Upsal, is especially valuable to the

Orthopterist.

Mr. Wood Mason has published the descriptions of various

new species of Phasmide, and has been able to determine the

sexual identity of various species which had hitherto been

regarded not only as distinct, but as belonging to different

genera.

The Rev. T. A. Marshall has furnished our Society with two

parts of the Catalogue of British Insects, devoted to the Ichneu-

monides adsciti, Chrysidide, and Oxyura, showing an amount of

labour which the loss of his collection by shipwreck has not

damped.

The commencement of a memoir on the Mutillide of South

America, by Dr. Gerstaecker, appears in the first part of the

40th jahrg. (volume) of ‘Wiegmann’s Archives,’ 1874; about one

hundred and twenty species are enumerated in this first part of

the memoir; and Mr. F. Smith has described a great number of

exotic fossorial Hymenoptera, during the past year, in the pages

of the ‘ Annals of Natural History.’

The investigation of our British Hemiptera and Homoptera

has been continued by Messrs. Douglas and Scott, in the ‘ Ento-

xlix

mologist’s Monthly Magazine,’ in which work also Dr. F. Buchanan

White has published a revision of the species of the very difficult

genus Corixa, and has described a curious structure in the male

insects, hitherto entirely overlooked, but which he thinks forms

portion of the genital armature, situated on the posterior margin

of the upper side of the sixth segment of the abdomen, and con-

sisting of a chitinous plate attached to a short pedicle, and

provided with from three to sixteen rows of closely-set teeth

resembling the teeth of a comb: to this organ he has applied the

name of “strigil:” it differs in almost every species, and will

doubtless prove of great value in determining the species.

The admirable works of Mr. Hewitson on Exotic Butterflies

and on the beautiful group of Lycenide still continue to appear

with due regularity; as do also those of Mr. Butler, and Mr.

Edwards on the Butterflies of North America.

Mr. Ward has also published the first part of a work entitled

‘African Lepidoptera, being Descriptions of New Species.’ 4to.

Longmans, 1873, with six excellent plates of butterflies.

Mr. Hermann Strecker has also issued seven parts of a new

work entitled ‘ Lepidoptera, Rhopalocera and Heterocera, Indi-

genous and Exotic,’ with very full coloured plates, containing

figures of (p. 1) Saturnia Gloveri, (pp. 2, 4 and 6) species of

Papilio and Pieris, &c., (pp. 8 and 5) many species of Catocala,

(p. 7) species of Smerinthus (fifteen figures).

Mr. Herbert Druce has given us a list of the Butterflies of

Borneo, with descriptions of various new species, in the Pro-

ceedings of the Zoological Society; in which work a remarkable

new genus of Papilionide (allied to the genus Sericinus, first

described by me in the Transactions of our Society), from the

South-Eastern Himalayas, has been described and figured by

Mr. Atkinson under the name of Bhutanitis Lidderdali.

Various new species of Morpho have been figured by M. Dey-

rolle, in the ‘Magasin de Zoologie,’ in which Dr. Burmeister has

also contributed excellent descriptions and figures of the larve

and pupe of several species of the same genus.

We have still to regret the non-accomplishment of the reason-

able hopes which we had entertained that our Government would

have thought fit—whilst providing several of the older and more

wealthy Scientific Societies with fitting places for holding their

meetings, as well as their libraries and collections—to extend a

helping hand to the smaller Societies, ike our own, which have

been doing good work in Science, although often struggling for

existence. This has not been done; and after the present

season—during which the Linnean Society has been kind enough

to continue to allow us to meet (as for several years past) in their

rooms in Burlington House—it will be necessary for us to provide

ourselves with a new meeting-room, and which it may probably

be considered desirable to have, in connexion with our library, in

Bedford Row, where it has so long been, or elsewhere if

necessary.

I cannot leave this chair without offering a few words of advice

to the younger members of our Society. Entomology is a

Science, not a pastime. The objects of our studies are not play-

things; they are amongst the most elaborate of the works of an

Almighty Designer,—‘‘ The hand that made them is divine.” As

such they are worthy of our most careful study and research,

which are capable of far wider extension than might at first sight

be imagined. To study insects properly it is necessary that the

STRUCTURE of the object under notice should be thoroughly, not

superficially, examined, not only externally, but internally. Its

HABITS also should be carefully studied, especially with reference

to the corresponding peculiarities which may be noticed in its

organization; the various changes it undergoes, from its earliest

appearance in the embryonic state, through its various TRANS-

FORMATIONS; its relations to other existing species; whether

those close structural resemblances which have been termed

AFFINITIES, or those wider or more general relations or points of

resemblance which have been termed ANALOGIES, and to some

of which the ill-chosen name of mimicry has more recently been

applied; the EcoNomicaL usEs of the species, whether bene-

ficial or obnoxious to man or other objects; the sEXUAL DIs-

TINCTIONS, more especially the amount of variation in the external

secondary sexual characters, such as difference of size, colour,

texture, or appendages; the amount of varraTion observable in

the individuals of which the species are composed, especially

with the view of determining how far these variations are

hereditary, constituting more or less distinct local races; the

GEOGRAPHICAL RANGE of the individuals of which the species con-

sist, that is, the DISTRIBUTION of each IN sPpACE; the relationship

of the species with extinct individuals, either of the same or

closely-allied species, tracing its DURATION IN TIME; the sysTE-

MATIC CLASSIFICATION, NOMENCLATURE, and synonymy, of the spe-

cies, both generic and specific, and its BIBLIOGRAPHICAL HISTORY,

tracing it through the various authors who have treated on it;

lastly, the relationships of the species with Nature in general,

the weight of each in the great scale of the universe, and the

effect of each in the mighty whole, which St. Pierre has so well

termed the HARMONY OF NaturE. He, and he only, who will

look at an insect or family, or order of insects, from these varied

points of view ; he who will not rest contented with the possession

of a specimen, especially if it be a rare one, or with the observation

of a single fact or two in its economy, or with its name and sup-

posed place in the system, but will take such a wide range of

vision as I have above sketched; he only is worthy of the name

of an Entomologist.
