Al riioirs NOTE.

It was at the instigation of mj' luuch-hiuifnted fiiend Dr. John Lawrence
LeConte that the idea of monographing the Corylophidii' first entered into my
mind : and this fact would alone be sufficient to induce me to dedicate the work
to his memory, even if I were not impelled to do so Ijy veneration for his
character, both as a man of science and a sincere Christian. In these days of
scepticism and infidelity, it is refreshing to find an intellect like LeConte's free
from the pride of human knowledge, and imbued with higher and more spiritual
aspirations ; ever seeking through the works of creation to promote the glory
of the Creator.

In his Address to the Academy of Philadelphia, in 1875, Dr. LeConte
set forth his views of the true harmony of science with religion, in language
scarcely to be surpassed for power or elegance. And in the following lines
he has left a faithful portrait of his own character, and- a lesson which many
would do well to learn. Speaking of the evident proofs of intelligence, as
distinguished from instinct, which are so commonly found, even in the insect
world, he says : " Since it is so difficult for us to understand the mental
processes of beings more or less similar but inferior to ourselves, we should
exercise great caution when we have to speak of the designs of One who is
infinitely greater. Let us give no place to the crude speculations of would-be
teleologists, who are indeed in a great part already refuted by the progress of
science, which continually exhibits to us higher and more beautiful relations
between the phenomena of Nature than it hath entered into the heart of man
to conceive. Let not our vanity lead us to believe that, Ijecause God has deigned
to guide our steps a few paces on the road of truth, we are justified in speaking
as if He had taken us into intimate companionship, and informed us of all
J lis counsels."

EDITOirS PREFACE.

By a mutual avrangemfut made with my lamented friend the late Rev.
Andrew Matthews, shortly before his decease, I agreed to lend him my assistance
in the publication of the present work. Unfortunately it was not destined that
he should live to see it actually in print, and at his decease his MSS., as
well as his most important collections of Micro-Coleoptera, passed into my
possession, and I have used every endeavour to fulfil my ol>ligation in regard
to the present work, although I fear many errors and omissions will be found
that would probably have been rectified had he lived to revise the work as it
was passing through the press.

In the systematic and descriptive part of this monograph the author only
includes those sj^ecies that he had an opportunity of examining himself, and
for the most part contained in his own collection. This collection now forms
part of my museum, and I have given a list — which will be found at p. 46 and
\). 215 — of the species of Conjhtphiihe and Splueriidce not represented in it:
and have indicated, so far as I have been able, the collections in which these
are to be found, as a guide to anyone wishing to consult the types.

Species only known to Mr. Matthews by description are included under the
various authors in the " Literature," and to these I have added some species
that were either overlooked by him or published since he had completed his
MS. ; other omissions that were discovered after this portion of the work had
been printed will l)e found in the Addenda.

The general arrangement of the matter and the descriptions are entirely
the author's own work, and are given just as he left them, except the correction
of any obvious errors that were detected, and in a few cases where he had
left lacunne ; in filling these up I have found his copious original notes, now
in my possession, of great assistance.

The Plates I. to VIII. have bfcii prepared Ivom the original drawings luaile
by Mr. Matthews with his well-known accuracy, the tij^iues having been most
carefully and successfully transferred to zinc by Mr. .1. Collin, of Newmarket,
and I have to thank him for the trouble he has taken to make them accurate
copies. Mr. Matthews has unfortunately left no note of the names of the
species figured, and I have been unable to trace in his collection which are
the actual s|)eciraens from which he made his drawings. Plate A of the
metamorphosis has been copied from the figures accompanying M. Perris's
memoirs, as acknowledged.

I have also to thank Mr. George Lewis, Mr. Champion, Mr. C. 0. Waterhouse,
Herr Reitter, and Signor Fiori (who acquired the Reitter collection), for assistance
given me: iind, ubovi all, Jlr. 0. E Janson. who has rendered most valuable
helj) in reading the proofs, in obtaining and verifying references to the literature,
and generally in getting the book through the press.

PREFACE.

The Corylophidce were first formed into a separate family by Mr. Stephens in
1830. The few species which had been discovered previously to that date were
promiscuously distributed among various genera, to which they bore little or no
affinity. Starting from the small foundation thus laid by Mr. Stephens, the
Corylophida have gradually expanded and increased, until at the present time they
form a numerous and very natural group, anatomically, if not superficially,
congruous in itself, and abundantly distinct from any other family.

The principal characters which distinguish the Corijlopliiche from other groups
consist in the form and peculiar folding of their antennae ; the great size of the
second joint of both the maxillary and the labial palpi ; the elongate and prominent
anterior coxae ; the minute size of the third joint of the tarsi ; and the great
enlargement of the first ventral segment ; to these may also be added the constant,
though less conspicuous, unilobed maxillge.

The antennte are divided into three main portions, of which the apical portion
is composed of three joints, and the basal of two joints, except in OUgarihrum, in
which genus the basal portion consists of a single joint only ; the intermediate
portion, or funiculus, varies to a great extent in the number of its joints, and on
this variation the distinction between many closely allied genera chiefly depends,
and, moreover, the relative proportions of these joints is a specific character of the
utmost importance. When the antennae are withdrawn for the purpose of conceal-
ment, or rest, the apical portion is folded vertically back upon the funiculus, and in
this position is received into a hollow space, for it can scarcely be called a groove,
extending along the inner side of the eye as far as the anterior coxae. It is obvious,
therefore, that such a position renders it a matter of considerable difficulty to
extend the antennae sufficiently to obtain a correct view of the number and
proportions of the minute joints of the funiculus. But, however difficult it may be,
such an investigation is indispensable, for, as I have already said, on the number
and proportion of these joints both the generic and specific distinctions often
entirely depend.

In this family, the organs of the mouth and proportions of the skeleton
of the under side, and also of the tarsi, are very characteristic, and generally

uniform. The unusual development of the second joint of the maxillary and the
labial palpi distinguishes the Corylophida from many other families, and prevails,
with trilling modifications, through all the genera ; although in the maxillary
palpi of Siirium and ArthnAipx this character is somewhat evanescent, yet in their
lahial palpi it becomes so strongly developed that these organs present the appear-
ance of small circular plates attached to tlie anterior extremity of the labium, and
it is only after immersion in Canada balsam that their true character can be ascer-
tained. In these two genera, and indeed in almost all the Corylophidce, the organs
of the mouth are so exceedingly delicate and fragile, that their dissection is a far
more diflficult operation than it would be in the case of the smallest Trichopterygian.

The two curious genera, Aphanocephalus and Phcenocephalus, discovered by
Mr. Lewis in Japan, and described as Coryhphid(e by Mr. Wollaston, differ so
widely in many essential points from the Corylophide type that a mere tribal
separation becomes wholly inadequate. Aphanocephalus exhibits, instead of the
normal uuilobed maxilla, a maxilla with three separate lobes, resembling the
maxilla of all the TrichopU'rygidd except in this one point — that the outer lobe, an
integral part of the stipes, is not placed, as in the Trichoptcrygidce, on the same
level as the true lobes, but rises from the middle of the outer disc of the stipes,
and does not extend for more than half of its own length beyond the base of the
other lobes. This lobe is vei-y conspicuous without dissection in the mouth of any
Aph a n oceph alits.

The stipes itself, which in the true Coryloplt'uhe is always small, sometimes
almost rudimentary, is in this genus as long and as large as it is in the
Trichopter/ifiidce. Again, in the rounded and wholly enclosed anterior coxae, and in
the enormous size of the mesosternal epimera, Aphanocephalus assimilates the
Trichopterygidce ; but in the shape and disposition of the coxal cavities it is unlike
that family or the Corylophida ; the same remark also applies to its antennae,
whose club appears to consist of a single articulation, and, although the separation
of the joints ma}' be discerned under a high power, at first sight it much resembles
the solid club of Sphceriun. In Aphanoccplialiis all the tarsi are distinctlj' three-
jointed, without any trace of the usual small penultimate joint ; its wings are also
formed on a very different plan, and in shape and neuration resemble the wings of
the Silphidce. In short, the large size of the first ventral segment is the only
Corylophide character in the skeleton of Aphanocephalus, although some affinity is
shown in the shape of the palpi and some other organs of the mouth. It is,
therefore, impossible to retain Aphanocephalus among the Corylophidce ; and, since
the genus cannot be placed in any other family, I have designated its species as
Vscudocoryloph idee.

An almost similar isolation occurs in the case of Ph(enoeephalus ; for, while
it possesses no single character in common with Aphanocephalus, its bilobed
maxillic and Silphide posterior coxae effectuallj' prevent its association with the true
Corylophidw. The only practicable course to pursue is to consider the genus as a
distinct family in itself.

It is not easy to determine correctly the systematic position of the Cory-
lopJiidfB ; from the peculiar formation of the anteuna3, from their position when at
rest, and from the large, elongate, and free or iirominent anterior coxse, and also
from the general arrangement of the skeleton of the under side, it is impossible to
ignore their close afiSnity to the Silphida. And for these reasons I believe that to
place the Corylophida before the Silphidce would be the most natural arrangement
that could be made. In external appearance many genera of this family present a
resemblance to the Anisotomhue so striking, that it is difficult at first sight to
determine whether they do not really belong to the Sllph'uhe. In Pdtinus and
some others the prosternum is reduced, as in Agathidium, to the smallest possible
dimensions, and leaves the coxal cavities open in front and behind. If, therefore,
the Corylophidce are placed before the Silphidce in proximity to the Anisotomince, a
much greater harmony of form and anatomy would be attained than by leaving
them where they now stand, or by removing them to any other position.

In the foi-egoing remarks I refer to the true Corylophidce alone ; those species
which I have separated into a distinct family, the Pseudocorylophidce, I would
retain in the position now occupied by the whole family — I mean in the vicinity of
the Coccinellidce.

The Pluenocephalidce make a yet further approach towards the Silphidce by
their bilobed maxillae, and by the contiguity of their posterior coxte, which are very
widely separated in all the Corylophidce. Like many Silphidce, the posterior coxa
of Phcenocephalus are also furnished with prominent trochantins, a structure never
found in the true Corylophidce. It may be thought unadvisable to create a separate
family for the reception of a single species, at present represented by a single
specimen. But I do not see any other course to pursue. The bilobed maxillse and
Silphide posterior coxsb are anatomical characters of too much importance to
permit the association of Phcenocepludus with the Corylophidce, and it is still farther
removed from the Pseudocorylophidce by every part of its anatomy. Since, then,
the very same characters which remove Phcenocephalus from the Corylophidce
indicate its affinity to the Silphidce, I feel that I am justified in placing Phceno-
cephalus as a connecting family between the true Corylophidce and the Silphidce.

By the above arrangement the Families would stand in the following order,

viz. : —

Leptinid.e.

cokylophid.e.

Ph^enocephalid^.

Silphide.

And thus a greater harmony of both form and anatomy would be effected than is
jDresented by any existing systematic arrangement.

In this work, as well as in others, I have often described the anterior coxal
cavities as "open in front and behind." Some entomologists, I find, object to the use
of that term, but I do not think that any other definition could express so accurately
the form of the part in question. It would be manifestly absurd to describe a cavity

as " closed at the sides," which has no sitle wall to enclose it. The coxal cavity is
understood to he a more or less cup-shaped hollow in the sternum, formed to
receive that i)ortion of the leg called the coxa. This cavity is often so far closed
on its upper side that it hecomes difficult to withdraw the coxa, and the articulation
thus formed assumes the shape of a ball-and-socket joint ; but, on the other hand,
as in man}' Stapliylinidce, the hinder part of the sternum is sometimes excised, and
the coxa left free and unconfined ; between these two extremes there exists every
possible modification in the form of this cavity. In the case of the genera referred
to above, it becomes a mere depression of the surface of the sternum without any
side walls in front or behind, and can therefore only be described as open in front
and behind.

By their geoKrai)liical distribution, the Con/lophi<liv seem to prefer the warmer
regions of the world ; the majority of those found in Europe occur in the more
southern parts of that continent, and very few above the latitude of Greenwich-
The comparatively large number of the European species may readily be accounted
for by the greater length of time since they attracted the notice of entomologists,
and the greater number of workers engaged in their pursuit. But, nevertheless,
like the Trichojiteit/gidte, they have been much neglected ; and the numerous
species lately added to their list prove that the Corylophidie are more abundant
than they were hitherto supposed to be.

In the following list I have included only those species which I have myself
examined ; many of those omitted are doubtless true species, but I cannot speak
of them from personal knowledge ; all such are, however, referred to in my
extracts from the works of other authors. Vide pp. 7-21.

It now only remains to me to express my warmest thanks to all who have
kindly assisted me : to Dr. Horn, Mr. Schwartz, Capt. T. L. Casey ; to MM. C.
Brisout de Barneville, Borre, Van de Poll, Fleutiaus, Salle, and Prof. Fiori ; to my
lamented friends. Dr. Leconte, Dr. N. A. C. Dohrn, Mr. E. W. Janson, MM. de
Marseul and Perris ; in my own country, to Dr. Sharp, Messrs. Champion, Lewis,
and Waterhouse, and especially to Herr Eeitter and Dr. P. B. Mason, I am indebted
for the means of bringing this work to completion. Without their help any
investigation of these obscure classes of Coleoptera must have been hopeless ; and,
indeed, to the generosity of my last-mentioned friend. Dr. Mason, its present
publication is entirely due.

LITERATURE.

In this part of my work I shall not translate the descriptions of antecedent authors
into Latin, as I did in my ' Trichopterygia Illustrata,' in order both to avoid the charge
of pedantry, unjustly imputed by some hypercritical reviewers, and also because the
original descriptions are for the most part fully and accurately detailed, and of modern
date. To facilitate reference, I have arranged the various authors alphabetically, and
not in chronological order.

BRISOUT DE BARNEVILLE (CH.)

Sacixim bninneum. — In the Appendix to M. Grenier's Catalogue this species is
fuUy described {ridf Materiaux pour la Fauna Francaise, p. 70).

Holopsis nigellus.
,, pallidus.

,, Lawsoni.
These species are described, somewhat cursorily, by Mr. Broun in the above work as
belonging to Holopsis, which he terms a genus of " Cranophorites" having nine jointed
antennae. The first and last named I have dissected, and found to be perfectly normal
species of Conjiophodes. H. pallidus is, I feel sure, a variety of H. nifidlus. H. Lawsoni
was originally regarded by Mr. G. E. Crotch as a Coccinellid.

described by M. ComoUi ; by ihe reference to Kunze, it would appear that the species had
previously been named by that entomologist in MS.

I have received types of tliese species from Herr Reitter and several other experienced
entomologists, and, having compared them witli M. Duval's original and very accurate
descriptions, I believe that the following notes will prove to be correct : —

S. rufithorax seems to be a good and distinct species of Arthrulips.

S. discedens is identical with, and long posterior to, ' '. obscuni:i, Sahlberg.

C. sublsevipennis is a well-known and genuine species.

Moronillus ruficoUiB. — This is also a well-known species, but the generic name is
posterior to l,'lii//'iiliiux, Le Conte.

Orthoperus pilosiusculus. — M. Duval's description of this insect appears to me
to point unuiistakubly to the species generally known as (>. curiareus, Key., and, since
M. Duval's name possesses an undoubted claim to priority, it should be retained.

[The author appears to have had some doubt on this point, and retained the name
curiaceiu for the species in the descriptive part of his MSS. — Ed.]

ERICHSON W. F.I

Corylophus thoracicus.
,, fasciatus.

Both species are well described. By the shape of its thorax the former evidently
belongs to Sericodents, and in size and colour agrees well with dark examples of .S. lateralis.
The latter, ' '. fasciatus, is the American Saciiim faseiatum, which, like many of its congeners,
varies much in size.

Until lately several species of Oithtijierm have been comprised under the name " lirun-
nipes, Gyll."; but through the exertions of M. Wankowicz and Herr Reitter these have now
been satisfactorily separated upon very evident superficial characters, and the original name
retained for that form alone which agrees the most closely with Gyllenhal's description.

A very similar confusion has also occurred in the case of Cossi/phax pusillus : this name
has been applied to several species of Sacinm, any one of which would agree fairly well with
Gyllenhal's cliaracters. I have therefore chosen as my type of Sacinm pnsillam the species
which bears tliat name in most of the chief continental collections.

In Pt. iv. App. p. 510, Gyllpiihal bi-- M'-'Tately described Sfricoderuji lateralis, also as

C. cassidoides, black, shining, front of thorax and legs yellow, thorax semicircular, with the
margins slightly reflesed, posterior angles acute, elytra moderately convex, sides margined.

Although the foregoing descriptions are too imperfect for identification without the aid
of types, the species seem to be distinct, since the characters given do not agree with any
others with which I am acquainted ; but from such scanty material it is not possible to
form any reliable opinion.

KRAATZ (G.)
Berlin Ent. Zeitschr. 1.S69, p. 285.
In this paper Dr. Kraatz reviews the nomenclature of several species of Saciiim and
Arthrolips, and gives the following synonymic list as the result of his observations : —

Saciura pusillum, Gyll. ; Thoms.

,, pusillum, Duval ? ?

,, obscurum, Sahib., not Dejean.

,, cordriiiiiin, Thoms.

,, pusUlum, Kedtenb.

,, atnim, Parreyss ; Zeigl. ; Dejean.

„ .' disct'deiix, Duval.

,, nanum, Mnls.

,, brunneiun, Brisout.

,, Maderse, Kraatz.

,, piisitlinii, Wollaston.
Arthrolips piceus, Comolli.

,, obi.ciinis, Duval.

,, vhxi-uim, Dejean, not Sahlberg.

,, var. conve.ciuscuius, Motsch.

,, humilis, Rosenhauer.

,, TKjitlioni.i-, Duval.

.Judging by the miscellaneous condition of the nomenclature of this family, it would
seem to me very doulitful whether some of the specimens submitted to Dr. Kraatz possessed
any affinity to the species whose name they bore on their labels ; at any rate, after a careful
examination of a large number of individuals, I have arrived in some instances at a con-
clusion differing from that expressed in the foregoing synonymy. All the examples of
Sacium obscurum which I have seen belong to the genus Arthrolips, and are totally distinct
from A. piceus. Of Sacium corticimtm I have only seen a single example, but this exhibited
11-jointed antenna. With regard to S. discedens, I quite agree witli Dr. Kraatz that it is
synonymous with .S. obscurum. Arthrolips rufithorax is a distinct and good species (if I can
judge from types in M. .Jekel's collection |, and cannot be associated with any other. In
the same collection there was a Sacium labelled .S'. nanum which was clearly identical with
Arthrolips rufithorax, and, since this is the only specimen I have met with bearing the
name " nanum," I am unable to express any opinion as to that species ; in Gemminger and
Harold's Catalogue 5. nanum is quoted as a synonym of S. pusillum. I have often seen
examples of A. humilis with their thorax rufescent, but these are totally diti'erent from
A. rujithorax both in size and shape. In this paper Dr. Kraatz very properly changes the
name of a Sacium found in Madeira by Mr. Wollaston, and called by him S. pusillum, into
.S'. Madera:.

LATREILLE (P. A.)

Cuvier, Eegne Anim. ed. ii. t. v. p. 162 (1858).

Cossyphus pusillus, Gyll., is made a separate genus by M. Latreille in the above

work, under the name Cbjpeaster ; but, since that name had been previously used for a

genus of Echinoderms, it was subsequently cancelled by Dr. Le Conte, and "Sacium"

substituted in its stead.

10

LE CONTE (J. L.)

In the Proc. Acad. Nat. Sciences, Piiilad. vol. vi. p. 142 et seq. (1852), Dr. Le Conte
described many new species of Corytophidtr, and one new genus, Wiyjntbius : he also
proposed the term Sacium for the genus previously known as Clijpeaster, a name which
had been already used to designate a genus of Echinoderms. In this paper he adopts
Micnts/ilitiiii, Redt., in the place of Oitliu/ifiiis, Steph. ; but seems afterwards to have
changed his mind, for in his later works he again uses Ortluipenis for that genus ; in so
doing he appears to have acted judiciously, for, although he accuses Stephens of having
inacouraioly described the antenmi? of his genus, yet immediately after he blames
Hodtfiiimcher for a very similar fault, and. when errors are mutual, it is certainly
preferable to retain the name originally given.

Dr. Le Conte's descriptions are good and characteristic, and easily recognized ; some
of them I have transcribed below, as I have been unable to obtain any authentic types of
those species ; but the rest I have myself described in the present work from specimens
kindly presented by Dr. Horn and otiiers.

and more broadly oval, very finely pubescent. Tliorax semicircular, with a dark spot near
the anterior margin. Elytra black, very finely punctulate, with a broad testaceous fascia

broadly rounded in the middle, sinuate each side, posterior angles moderately produced.
Elytra very finely and densely punctulate, very slightly narrowed to the apex, which is
broadly truncate. Pectus dusky.

[I find a note among the MSS. that this is identical with .*?. hitfinlis. — Ed.]

Sericoderus obscurus. — Rufo-piceus, flavo-pubescens, tiiorace lateribus rufis, basi
utrinqiie subantjnlato, elytris snbtiliter pimctulatis, apice pedibusque flavis. Long. -025.
One specimen, New York. — Smaller than .S'. //((ridits and a little narrower; the thorax is
more broadly rounded in the middle, and the posterior angles are more produced, forming
■with the middle of the base a distinct angle ; the elytra are a little more narrowed behind,
and seem more distinctly punctured ; the truncated margin is yellowish ; beneath dusky,
feet and tip of the abdomen yellowish.

Sericoderus subtilis. — Flavo-testaceus, flavo-pubescens ; thorace macula antica
obsctira uotati). angulis poaticis valde productis ; elytris punctulatis. Long. -02. Illinois,
Wilcox. — Smaller and more convex than .S'. jhividiis, with the thorax not so transverse, and
the posterior angles much more produced ; the elytra are more narrowed posteriorly and
more distinctly punctured ; the pectus is scarcely darker than the abdomen.

In the Proc. Amer. Philosoph. Soc. xvii. p. 899 (1878), Dr. Le Conte described
three species of Orthopems, viz. 0. Scutellaria, (). siUnnilis, and O. eloiii/atus : of these I have
only seen 0. scutellaris, but this proved on dissection to belong to Spiiaiiits. The following
are his own descriptions of the other two : —

" Orthoperus suturalis.— Oval, rounded, slightly convex, piceous-black, glabrous,
shining, scutellum distmct, elytra with a very fine sutural stria slightly visible "from the
middle to the tip. Long. -05 mm. = -02 inch. Enterprize, Florida. — Smaller, or of the
same size as 0. i/lahcf, but easily known by the distinct scutellum, and fine sutural stria ;
the elytra are very sparsely and indistinctly punctulate, as in the preceding.

"Orthoperus elongatus. — Oblong, elongate, convex, piceous, moderately shining ;
scutellum distinct ; elytra with a very fine sutural stria, effaced behind, but curving in front
around the base, and_ ending half-way between the scutellum and the humerus, tips
separately rounded ; with the apex of the abdomen more prominent than in the other
species. Long. -05 mm. = -02 inch. Tampa, Florida.— Smaller and narrower than the
other species, very much the form of a I'tiliuiii."

[This species is described in the Biol. Centr. Amer. col. ii., part i. p. 105 (1887), as
uEnir/iiiaticniH iitilioides, n. s. — Ed.]

In the Bull. U. S. Geograph. and Geolog. Survey, v. p. 512 (1879), Dr. Le Conte
described a new species of Sxeiiwi, which he named .S'. biiiuttatuni : but, since I have not
seen any type of this species, I can only quote his original description : —

" Sacium biguttatum. — Elongate, black, very finely pubescent ; prothorax not
wider at the base tliau its length, sides and apex strongly margined, diaphanous in front
for nearly one-third of its length ; elytra each with a rounded red spot a little behind the
middle and half-way from the suture to the side ; under surface and legs black. Long.
1-6 mm. Vita Pass, Colo. — Of the same size as S. tuguhre and S. uhscuniin, but the
prothorax is rather longer, and the elytral spot distinguishes it at first sight."

To attempt to identify a species by the vague remarks which represent descriptions in
this work would be perfectly useless. D. CasMoides has nevertheless been retained for the
Corylophus which now bears that name, owing to its subsequent adoption by Mr. Stephens.
— D. jyicatus and D. punctum are supposed to represent respectively the well-known species
of Orthoperus — O. atomus, Gyll., and 0. atomarlus, Heer.

Obs. In the lonp; essay from which the foregoing descriptions have been transcribed
most of the species appear to have been found on the " Mountains of Nura Ellia," but on
p. 117 one is mentioned from Colombo, Ceylon.

It is much to be regretted that references to Col. Motschulsky's types is now impossible,
except by a pilgrimage to Moscow. From my own experience of his correctness in
distinguishing the species of Tiicli'ipterijiiidiF, 1 believe that the greater part of those
named by Uol. Motschulsky in the foregoing extracts would prove to be good and
genuine species. But, since the descriptions are wholly inadequate for identification, his
species must be held in abeyance until some naturalist, well qualified for the task and
favoured by accidental advantages, may bo able to restore their names to the muster-roll
of science.

" This species has been confounded with <K corticalix. but is smaller, sides of the thorax
more rounded and less margined, elytra more distinctly alutaceous, and less distinctly
punctured. Intermediate between 0. corticaUs and O. pilosinscidus."

Obs. In the foregoing extracts from MM. Mulsant and Rey I have transcribed the
Latin, and quoted the more important parts of the French descriptions, for I cannot
perceive any character by which O. anxiufi can be distinguished from 0. coriaceus : but.
since I have never seen an authentic type of the former species, it would be unfair to
express any opinion as to their identity ; and the same observation applies equally to
C. 7ianits.

On p. 121 of this work the new genus Peltinus, and its species P. velatus, are fully
and accurately described.

FERRIS (E.)

Annales de la Societe Eiitoinolof,'iqii-- de France, 1852, p. 587.

Md-moires de lu Societe Koyiilc- des Sciences de Liege, t. x.p. 270, &c. (1855).

Li tbe former of these publiciuions M. Perris describes iu an exlinustive manner the

various stages of "/t/iii/'c/'io /;ic<;m4- i /<;k»i>h'/«'.<, Gyll.), and in the latter those of Aitlnolips

pici-iu.

These uriginal observations of a naturalist so well known and so distinguished as
M. Perris form an invaluable record of the life-history of the ' 'o)i/lo/Jiiil<r : and, since it has
never been in my power to mal;e any similar inve.sii<;alions, I have availed myself of the
re.searche.s of M. Perris, and in their pioi]er plaee have transcribed at great length his
descriptions, and have carefully copied his figures of the larva and pupa of both species.
From the strong resemblance which these two extreme forms bear to each other, it may
well be concluded that the intervening genera would not differ much from their type.

PHILIPPI (R. A., iuul F.)
Stettin. Eut. Zeitung, IBGi, p. 404.

Clypeaster variegatus. — " L. c. li lin. Ovatus, pubescens ; prothorace sordide
cameo, punctis maculisque fuscis plus minusve picto ; elytris sordide carneis, maculis
punctis(jue fuscis et nigris marmoratis ; corpore subtus. pedibiisque rufi> fuscis. Hab.
Valdivia."

I have copied Dr. Philippi's description verbatim, because it is not sufficiently definite
to justify any positive conclusion ; but I am much inclined to believe that probably both
Sttciiim Oberthiiri, Keitter, and .*>. hunt u in, Matthews, will prove to be identical with
^'. vaiicyatuni , Philippi, although the fact can be ascertained only by comparison with the
type-specimens in the collection of Dr. Philippi.

In extensive genera, like Saciiim or Tiiclm/iteiiix, it must inevitably happen that many
species of science will prove to be merely local forms of more comprehensive species of
nature. But it is far preferable to consider as distinct species those forms which exhibit
distinctive specific characters, such as shape of outline, sculpture, convexity, &c., than to
amalgamate indiscriminately diverse forms under one specific name, which would thereby
lose its identity, or to have recourse to the objectionable habit of creating subspecies or
subgenera.

REDTENBACHER (L.)
Fauna Austriaca, ed. ii. p. 299 (iSoS); ed. iii. p. 327.
Orthoperus corticalis. — The only copy of the Faun. Aust. to which 1 have had
access was one of ed. iii. ; but the short description of .1. cortiailis given on p. 327 agrees
perfectly with types of that species in the collections of Herr Keitter and other continental
entomologists. On p. 543 of the s.ame edition Herr Redtenbacher appears to consider that
his genus Oiypkinus is identical with Seiicodenix.

REY (C.)
L'llchange, Revue Liuueen (Lyon), No. 50, February 15tli, 1889.

In this periodical M. Key has published some critical notes on various species of
Coryla/ihida:. Of many of these notes I am unable to form any trustworthy opinion, and in
all such cases must be content to transcribe his observations, confining my own remarks to
those species with which I possess a more perfect acquaintance.

Sacium Rhenanum, Reitter. — "This species corresponds with Clypeaster nanus,
JIulsant anil Itey. The latter is distinguished by the obsolete punctation of the elytra, and
an oblong sutnral impression situated behind the middle."

Clypeaster lividus, Dejean. — " This is a testaceous variety of C. hrunneus, Brisout."

15

Clypeaster discedens, -J. Duv. — " This seems to me to be distinct from C. obscums.
Sahib. It is rather more compact {ramassei, the elytra are more faintly punctured, and
their suture more finely, or scarcely at all, elevated behind,"

Clypeaster nitens, Rey. — " Closely allied to S. densatum, Eeitter. It is nevertheless
distinguished by its rather more parallel shape, more shining surface, and especially by its
more rounded sutural angle of the elytra. — Spain."

Arthrolips regularis, Reitt. — "This species is found in Provence. The variety
A. hci-iculUs, Rey, is possibly a distinct species. It is perceptibly smaller, the prothorax is
almost smooth on the disc, the elytra are ver.y obsoletely punctured, and more contracted
behind. — Hyeres."

Corylophus nigripennis. — "I have separated from ('. xnbltivipmnis a Conjlophus of
a slightly smaller size, with almost entirely black elytra, equally finely punctured, but with
the interstices smoother and more shining. It may be merely a variety."

Orthoperus peregrinus "is perhaps O. an.vius. It is smaller, rather smoother
and more shining than O. an.rius : less shining and less distinctly punctured than 0.
pilosiusculus."

Of the species thus noticed by M. Rey, I have not seen types of Clijpeiister nitem,
Arthrolips Itcvicollis, (\iri/loj>hns iii//njieiiHis, or Arthrolips perccirinus, and therefore cannot
express any opinion of their merits ; but I have received from various sources specimens
labelled " .5. nanum." Of these some were identical with S. densatum, others with S. pusil-
lum, and one with Arthrolips rufithorax; but none resembled Sacium Rhenannm.

The only type of Clypeaster lividus which I have seen was identical with Sericoderiis
lateralis.

I have examined many examples of C. discedens, and all have proved identical with
Arthrolips obscurus.

In the foregoing observations I have merely recorded my own experience, but in the
confused state of nomenclature prevailing in this family it would be rash to assert any
claim to infallibility. Specimens often seem to have been labelled promiscuously or by
conjecture ; in one collection I met with Sacium pusillum represented by a miscellaneous
series comprising S. Damryi, densatum, and latum, Arthrolips humilis, Sericoderus lateralis,
and Anis. nerelierii.

RYE (E. C.)
Entomologists' Monthly Magazine, vol. x. p. 167 (1873).
A new species of Aphanocephalus is here described by Mr. Rye under the name of
A. Wollastoni. The description is short, and does not enter into details.

REITTER (E.)
Herr Eeitter has done much good work among the ' 'un/lophidtr, and increased the list
by the addition of twenty new species, separated with correct discrimination, and described
with his wonted accuracy.

In ' L'Abeille,' vol. xvi. pp. 1-12 (1877), he has given a revision of the species
Sacium and Arthrolips, and to those previously described added the following new
species, viz. : —

Sacium Rhenanum.
latum,
orientale.
densatum.
Arthrolips regularis.
,, ferrugatus.

To these he subsequently added many other species at different times, and in various
publications.

Sacium atrum.
Sericoderus castaneus.
,, fulvicollis.

In Verbandlungen der Kaiserlicbe-Koniglichen Zool.-boianiscb Gesellschaft iu Wien,
1878, pp. lG'J-194, be describes the foUowiug species, viz. : —
Arthrolips similaris.
Oberthuri.
,, fenestratus.

Sericoderus pallidus.
I have not seen a type of A. similnrLs, but tbe immense series of A. {Suciwn) Oberthuri
taken by Mr. Champion in Central America proves beyond a doubt that that species is
liable to vary niiicb both in size and in tbe markings of tbe elytra, and for this rea.son I am
inclined to tbiiik that .1. similaris is a variety of .^. Oberthuri. The former of these is thus
described by Ilcrr Keitter : —

" Arthrolips similaris, n. sp. — Oblougo-ovalis, breviter pubescens, fuscus, protborace
(macula oblonga in medio .sita excepta) fascia elytrorum transversa communi, extus abbre-
viata, paulo pone medium, et margine apicali, pygidio, anteunis pedibusque, plus minusve
rufo-testaceis. Long, plus 1 mm."

To this description he adds that it is "quite like tbe following {A. oherthmi] in form
and colour, but smaller, more closely and more finely punctured, and chiefly distinguished
by tbe shorter and more silky pubescence ; the spots on the base of the elytra appear to be
wanting in this species."

In Deutsche Eut. Zeitschr. 1884, p. 58, be describes : —

Sacium Damryi.
In Deutsche Ent. Zeitscbr. 1884, p. 117 : —

Moronillus pumilus.
And in Wiener Ent. Zeit. iv. p. 273 (iHHoi:—

Arthrolips Simoni.

,, alutaceus.
It would be useless in this place to truu.scnbe verbatim tbe accurate and satisfactory
descriptions of Herr Eeitter, especially since all the species except two will be fully de-
scribed in the subsequent pages from authentic types kindly transmitted to me by himself.

Among tbe foregoing notices of Herr Reitter's publications, I find that I have omitted
to mention the following in their proper places : —

In Deutsche Ent. Zeitschr. 1878, p. 12G : —

Sericoderus Revelierei.
In Deutsclie Eut. Zeitschr. 1H7(;, p. 312; 1H78, p. 199 :—

These arc well described, and tliu distinctive characters of A. humilis clearly defined in

the following words:— '• Distinguished from S. pic em by the greater and more regular

17

roundness of its body, by the elytra being scarcely enlarged behind the shoulders, and by
the smooth interstices of the thorax."

M. Duval is probably correct in supposing M. discolor, Rosenh., to be merely an imma-
ture condition of M. rnticnlUs, Duv.

The generic names given by Mr. Stephens have been universally accepted by sub-
sequent writers more from courtesy to their author than from any inherent validity ; indeed,
the claim of priority is the only plea that can be urged iu their favour, for it is impossible
to say that they were described by him. But, although his genera have thus been allowed to
stand, a similar concession could not be extended to his species, for even conjecture would
fail to identify any of them. The term Cori/lopltus was substituted by Mr. Stephens in his
' Manual ' for Clypeaster, Latr.*

SCHWARTZ (H.)

Proc. American Philosophical Soc. xvii. p. 356 (1878).

Mr. Schwartz, in this paper, has very accurately and distinctly described two new
species, viz. .?. mnUimiiii and .S'. sphndens, and very kindly sent types of both species to me,
from which I have made my own descriptions. I have placed both species in the genus
Artkrolips, since then* antennm, when immersed in Canada balsam, exhibit only ten
articulations.

THOMSON (C. G.)

Skaud. Col. iv. p. 118 (1863).
Sacium corticinum.

The only type of S. corticinum which I have seen was in the collection of M. S. de
Marseul ; this specimen distinctly exhibited 11-jointed antennje, although in size and
colour it much resembled Artkrolips obscurus. The species is carefully and accurately
described by M. Thomson.

was made by Stephens in his ' Illustrations of British Entomologj-,' Mandib. vol. v. (Supplement),

accepted ; (ilfCDsoma had been previously described by Dr. Le Conte under the name of
llliii/inhhu : Aphaiwrephiihis and Plucnocephidits are still retained for their respective species,
but I have separated them from the Corj/lophida: on account of their totally diverse anatomy.

All the species described by Mr. Wollaston as new to science still bear the names
which he gave them, but tiie one which he supposed to be identical with <'. imsillum, Gyll.,
subsequently proved to be entirely distinct from that species, and was redescribed by Dr.
Kraatz as .S'. madene. My own descriptions have been made from types kindly presented
to me by Mr. Wollaston and Mr. Dale.

In order to bring the resume of the literature of the Con/lopliida up to the

I have in all cases tiuoted the original words, and not translated them. These

same thing as S. brunneiim, Bris., of which that author had given him types. The latter
name therefore sinks into the synonymy of Sacium nanum, Muls,

COEYLOPHID.E.

METAMORPHOSIS AND LIFE-HISTORY OF THE
CORYLOPHID.E.

(Plate A.)

We are indebted for all that is known of the life-historj- and metamorphosis of
the Corylo})hid(e to the researches of the late M. Ferris, of Mont de Marsan. In
the ' Auuales de la S. Ent. de France,' 1852, jd. 587, he gives a detailed account of
the larva and pupa of Orthoperus ; and in an essay, published in the ' Memoires de
la Societe Pioj-ale des Sciences de Liege,' t. x., 1855, p. '270, &c., he describes at
great length and with great perspicuity the anatomy, as well as the outward form,
of the various stages of ArthroUps. He also adds many valuable observations on
their habits and mode of life, and in plate v. of the same work gives excellent figures
of the larva and pupa with many dissections ; and, since in this part of the world
we have no opportunity of making such investigations, I shall, in their proper
place, transcribe almost verbatim M. Ferris's descriptions. With regard to their
mode of life, M. Ferris seems to think, although he mentions it in a conjectural
manner, that these animals are more or less carnivorous (a fact asserted in the
' Fourth Report of U. S. Entomological Commission,' p. 97, in the case of a kindred
genus Sericoderus), and I think that the anatomy of the mouth in all the tribes of
the Corylophidie except Saciina fully corroborates this idea. In the Saciina alone
the mandibles are of a feeble character, but even among them the single lobe of
the maxilla is of a decidedly carnivorous type. It seems more than probable that
the food of the Coriilophidie is of a varied description, and that M. Ferris, judging
from the condition in which he found the larvae, as well as the perfect insect — i.e.
under the decaying bark of trees — is right in supposing their nourishment to consist,
in part at least, of detritus, or of the excrement left by x_ylophagous animals. The
observations of M. Ferris refer especially to the Saciind, and throughout that tribe
the shape and peculiar articulation of the mandibles, and the fact that their edges
do not traverse each other, but close together after the fashion of pincers, combine
to give these organs the action of a spoon — a very necessary power if M. Ferris's
conjecture as to their food is correct.

LARVA OF AETHROLIFS.

L. c. 2 mm. — Body elliptic, depressed, greyish-white above, paler beneath,
upper sm-face covered with robust, truncate, rufescent hairs, either cylindrical or
inversely conical, longest on the back and sides, interspersed with a few longer
hairs.
Stigmata, nine on each side ; of these two are on the mesothoracic segment, and two

on each abdominal segment.

24

Jfiad small, imicli narrower than the thorax, puhorbicular, rather flat, dusky
rufescent, with two small longitudinal channels on the disc, furnished in front
and on the sides with tine hair.

Epigtoina transversely linear.

fjaliriim very small, transverse, semielliptieal.

Mau(Ublts moderately long, narrow, arcuate, pointed, but not dentate.

Mtuilhe and mrntum large, forming a single organ, distinguished from each other
by a supertieial channel on each side, together occupying more than half of the
under side of the head. MaxilliB ovate, without any visible lobe.

MaxilUirji piiljii prominent, three-jointed ; one very short ; two rather longer ; three
slender, as long as the preceding two.

Labium short, transverse, very faintly emarginate.

Labial pnlpi small, biarticulate, extending slightly beyond the second joint of the
maxillary palpi.

All these organs are rufescent.

Aiitfitiue inserted on the sides of the head, moderately long, four-jointed ; one short
and thick ; two slightly longer : three nearly as long as the preceding two,
furnished at its extremity with three or four small hairs ; four, the longest of
all, slender, and furnished with one long and two or three shorter hairs.
Below each antenna and opjiosite to its base there is a round ocellus.

Protlioni.r nearly twice as long as the head, rather narrowed anteriorly, deeply
bisinuated at the sides, with a large subtriangular brown spot on the disc,
divided in the middle by a whitish longitudinal line, with an indistinct
transverse fold near the posterior margin.

Mesothontx and metatlioni.r each shorter than the prothorax, with a rather indis-
tinct fold on tlie middle.

Abdoiiini subconical, composed of nine segments, nearly equal in length, the four
first gradually broader, the live last gradually narrower ; all except the last
very convex, with deep intersections, and marked with a deep fold on the
middle. The apical segment is semidiscoidal, rufescent, flat, and subcorneous
above, furnished on the under side with an extensile process.

Lc'ia six, two on each thoracic segment, short, subconical and livid ; coxa robust ;
trochanters very small ; femora strong, cyliiidric ; tihiie as long as the three
preceding articulations, conic, and furnished with hairs ; tiirs) represented by a
long Bubulated claw, dilated beneath at the base, and furnished with a very
long bristle spatuliform at its extremity.

PUPA.

M. Perris does not give any detailed description of this stage ; he merely
makes the following observations : —

" The nymph is at first white, afterwards rufescent. Its various parts are
closely wrapped together, and l)ut little elevated. The margin of the prothorax,
the sides, and the dorsal surface are covered with fine and very close hairs of
une(jual length. The extremity of the abdomen is entire, and almost smooth."

LARVA OF ORTHOPEEUS.
L. c. 1-1 1 mm.— Body composed of twelve segments, elliptic, dejn-essed, livid-
white, paler on the under side, covered witli very minute tubercles regularly
arranged, bearing stout conical hairs forming a fringe at tlie sides ; thoracic segments
strongly developed, especially the first, marked with a transverse fold terminating
in a depression on each sidej giving the appearance of a double segment ; on the
prothoracic segment is a subquadratc brown spot, divided longitudinally by a white
line ; ahdominal segments short ; apical segment semiellipsoidal, furnished beneath
with a small extensile protuberance.
lle,id small, oval, livid-white, darker towards the base, furnished with a few hairs.

25

Antenna; inserted on the hinder part of the head, slightly arcuate, three-jointed ;

one short ; two nearly twice as long as the first ; three as long as the

preceding, but more slender and rather subulated.
Epistoma short. Lahruin broad and prominent, circularly rounded in front.
Maxillary jMlpi very i^rominent, three-jointed ; one rather long and stout ; two

shorter and more slender than the first ; three as long as the two preceding,

robust, incrassate near the middle, especially on the inner side, with a single

long hair at the apex.
Maxilhe unilobed ; lobe large, trapeziform, with the anterior angle acute.
Labium short, not prominent, quadrately truncate.
Labial palpi small, two-jointed.

Mandibles moderately robust, slightly arcuate, acutely pointed, and rufescent.
Legs short, three-jointed, furnished with bristles, and terminating in a faintly

curved hook or claw.

PUPA.

Of the pupa of Orthoperas, M. Perris merely says that is fixed in position by
its posterior part encased in the white skin of the larva, and is divested of every
hair and every appendage.

Mr. Matthews unfortunatelj' did not label the specimens he described as types ;
he only put the same number on each specimen of a species. Some of these are to
be found in various collections, and not always labelled with the names he finally
adopted. I have, therefore, thought it would be useful, as far as I am able, to give
a list of those species which are not represented in his own collection, now in my

Note. — The name 0. minutissimus does not occur in the mauuscript list ; but,
as there are numerous specimens in the collection labelled with this name, and also

best to insert both name and description in brackets.

From the description and the specimens, it is, I think, synonymous with
0. perpusillus. — Ed.

GENERAL CHAEACTEES.

Body variously formed, elongate, more or less oval (Saciina) ; sbort, more or less
attenuated posteriorly (Sericodcrina) ; rounded (Orthoperina) ; or more or less
hemispheric {Corylophina).

Head generally small, often completely covered by the pronotum, sometimes more
or less exposed ; eyes often large and prominent, with the facets large and few
in number.

Anteniue very variable generically in the number of the joints, the two basal joints
always large, and the apical forming a much inerassated club ; sometimes one
or niore of the intermediate joints are enlarged, but all are generally short
and small.

Palpi short and often very robust, ma.rillary four-jointed, and labial three-jointed.
Their most distinctive characters are the excessive enlargement of the second
joint of both labial and maxillary, and the small size and shortness of the
third joint of the maxillary ; the apical joint is generally slender and sub-
conical. In Saeiitm and Artlirolips the labial palpi are circularly rounded on
the outer side, the second joint being broadly cyathiform, and the third very
large and very broad.

Lahniiit variable in size, generally ovally rounded, and often emarginate in front.
In Aiihaiiovejiliidiis the labrum is furnished with a semi-oval lamina attached to
the middle of its upper surface, and extending beyond its anterior margin.

Mandihleii variable, generally very strong, and much rounded at the back, strongly
hooked at the apex, and often armed with long and sharp teeth. In liln/pobius
the mandibles are long and very slender, deeply bifid at the apex, with each
extremity terminated with a sharp hook.

MaxilUe short, unilobed in all tribes, with the lobe long and strong ; armed at its
apes with sharp curved teeth. In lihypubiits and some other genera the inner
edge of the lobe is simple.

31

Mentum moderate, subquadrate, or transversely oblong, sometimes dilated at the
base.

Labium oblong, sometimes very short, generally furnished with paraglossae at its
anterior extremity. In Sacium and Arthrolips the labium is long and narrow,
strengthened at the sides by strong and apparently articulated costae.

Lingua, in many genera, large and very broad, usually more or less emarginate in
front.

Proriotum with its anterior margin generally entire, and circularly or ovally
rounded ; but in some genera excised to receive the head.

Scutelluin generally small, rounded or subtriangular ; subscutellum very large and
broad.

Elytra variable in form, generally rounded at the extremities, sometimes entire.

Wings ample, narrow and strongly nerved at the basal third of their length, and
from thence expanded into a broad oval membrane, in which the neuration is
inconspicuous ; hinder margin fringed with short setae. In Corijlophodes the
basal portion is furnished on its hinder margin with a long oval winglet.

Abdomen composed of apparently seven segments, of which the two apical are
corneous, and the rest membranaceous.

Prothorax generally very small, with the prosternum very short, often elevated
between the coxse ; cpisterna minute, often inconspicuous ; epimera moderate,
generally enclosing the coxal cavities ; coxal cavities oval or elongate, not con-
tingent. In Corylnphus and Corulophodcs the coxal cavities are open on both
sides.

Pectus with the mesostcrnum generally short; cpisterna large; epimera numevous
and narrow, not reaching the coxal cavities in unj genus except Microum and
Ectinuccphalus ; coxal cavities rounded and moderately distant.

Metasternum often very large, not extending to the sides of the body, with its
hinder margin straight between the coxje ; epistema very long and large,
sometimes reaching to the hinder coxae ; epimera long and narrow, generally
concealed by the epipleural fold of the elytra, sometimes with their extremities
inflexed beyond the episterna. Posterior coxae always remote.

Venter composed of six segments, the basal segment is nearly equal in length to
one half of the venter, the other segments are generally equal to each other,
the apical being simple.

Legs, anterior, with the cox(e generally oval, sometimes elongate and narrow, more
or less free or prominent ; trochanters small, trigonal ; femora simple, often
robust ; tibite generally simple, sometimes dilated near the middle, in Orthopcrus
elongate and incurved, and bluntly hooked at the apex, with the tarsi articu-
lated above the extremity of the tibia ; tarsi four -jointed, one generally long
and simple, two rather shorter than one, generally much jjroduced and deeply
bifid at the lower side of its apical extremity, three usuallj' very minute, four
slender and long, thickened towards its extremity ; claics generally slender and
faintly curved, sometimes with an obtuse denticuiation on the under side of the
base.

intermediate and jjosteiior very similar to the anterior, but much longer.

Coxa, anterior, nearly contingent, more or less prominent.
intermediate moderately distant.
posterior always remote.

Some additional observations seem to be needed with regard to the mandibles,
since it is diiScult to express by delineation the correct form of these organs in
many genera of Corylophidce.

In the Saciina and in some others the stipes is long and flat, placed at the side
of the head, and connected at its extremity with the mandible by an almost straight
transverse suture. The mandible itself is short and broad, very convex on the
outer side, and on the inner side deeply concave, in the form of a sjjoon or scoop.

32

In front it meets its fellow mandible, after the manner of pincers. This may be
regarded as the tyiiical form among the Corylophiche ; it attains its utmost develop-
ment in Coriilii]>lii>ilix, and seems to indicate that their food would consist in soft
decaying vegettible matter.

In lilii/pobiits and several other genera the mandible assumes a totally diflferent
shape. It is very long iiud slender, armed at its extremity with hooks ; it is
attnihed to the stipes much in the same way as the Saciinu, but the stipes itself is
free and folded baeii within the mouth, so that it appears capable of extruding the
mandible considcralily in front of the head.

In Pdliniix and Orl)i(>}n-riis the form of the mandible approaches more closely
the carnivorous type.

The CorjilophiiUe thus constituted may be divided into five tribes, distinguished
from each other by the following characters : —

/Mk/ exposed Phanerocephalina.

,, concealed, or nearly concealed, by the pronotimi.
iVn.i77Z</(i/ //(»/y/( with the second joint simple ... ... Saciina.

,. ,, with the second joint strongly incrassated.

Kli/tni triiucaie ... ... ... ... ... ... Sericoderina.

,, entire.
//'</</ entirely concealed ... ... ... ... ... Corylophina.

., partly visible Orthoperina.

Tribe I. — Phanerocephalina.

This tribe is simply a miscellaneous collection of genera which are elongate in
form, but agree in no external character except the protrusion of the head. I have
thought it better to class them thus together than to divide tliem into sei)arate
tribes, since, if this were done, each genus would require a tribe for itself. If in
l^rocess of time other genera should be discovered bearing athuity to either of those
at present knowni, a further subdivision might then be properly made.

The genera now constituting the I'liauvrociphalimi maj" be distinguished from
each other by the following characters, viz. : —

Thorax widest near the middle .ffinigmaticum.

,, ,, at the base

Anterior margin of the pronotum entire, head prominent ... Ectinocephalus.

,, ,, ,, ,, deeply incised, head sessile Conodes.

This genus is the most abnormal of all the Corijlophidic, and in outward form
bears no resemblance to any of the family. But its whole anatomy is so purely
Corylophide, that no doubt can exist as to its proper position. In this respect
^■Enifimiitieum affords an apt illustration of the importance of the external skeleton
of the under side, combined with the organs of the mouth, in seeking a correct
clue to the systematic position of an unknown genus. In all these points it differs
but little from the most nornuil type of llie family. This is clearly shown by the
unilobed maxilire, the large size of the second joint of all the palpi, and the length
of the first ventral segment, although on the upper side the autennie alone present
any Corylophide character.

Obs. — I described this as a new species in the Biologia Cent. Amer. Col. II.,
Pt. I., p. 105, 1887, from specimens taken by Mr. Champion in Guatemala, but I
have lately (January, 1894) been informed by Capt. T. L. Casey, U.S. Engineers,
that it is identical with Orthoperus elongatus described by Dr. Le Conte in the
Proc. of the American Philosophical Society, xvii. p. 399, 1878. Capt. Casey
has carefully examined the original types in the collection of Dr. Le Conte, now
preserved in the University Museum at Cambridge, Mass., and, from his accurate
knowledge of minute Coleoptera, I feel no doubt that his determination will prove
to be correct. In this case the specific name given by Dr. Le Conte must be
retained, and the species be termed in future JEnigmaticum elonyatwm, Le Conte.

in the mesosternal epimera, which extend to the coxal cavities, and from all in the
shape of its head. The head is wholly prominent, and is fitted to the anterior
margin of the pronotum by an occipital ridge, after the manner of the Cholevina.

This pretty genus is distinguished from the rest by its depressed conical form,
deflexed and sessile head, and by the deep excision of the front of the thorax.
Like Ectinocephalus it bears an external resemblance to the Criiptophagidce, but is
strictly Corylophide in its anatomy. On account of their rarity I have not ventured
to dissect the mouth of this or the preceding genus, and therefore cannot accurately
describe their buccal organs, but the more prominent parts, especially the maxillary
palpi, are sufficiently visible under a high magnifying power to convince anyone
that they are of the usual Corylophide type.

Tribe II. — Saciina.

This tribe contains a greater number of species than either of the others,
distinguished chiefly by their small narrow head, and by the peculiar form of their
palpi. They may also, with but few exceptions, be recognized by their elongate
oval shape, pubescent surface, and great convexity of their under side.

The four genera at present known may be distinguished from each other by
the following characters, viz. : —

Antcnum 11-jointed ... ... ... Sacium.

,, 10-jointed
Thorax with tlic posterior angles not produced.

,, moderate; maxillary palpi narrow and elongate ... ... Arthrolips.

,, very small ; maxillary pal])! very broad, patelliform ... Meioderus.

,, with the posterior angles produced ... ... ... ... Meizoderus.

The species of this extensive genus are in many cases difficult to distinguish
from each other, chiefly on account of the similarity of their superficial sculpture.
The slight differences which do exist, although sufficientlj- perceptible to the eye,
are extremely difficult to define intelligibly by description ; to say that one species
is more deeply punctured than some other implies the necessity of comparison, a
process often unattainable, especially among the rarer kinds. I have reason to
think that some of the species described in the following pages are merely local
races, but, since they have been considered by other authors to be distinct, I have

43

retained tliem as such in this work ; to sink a species is always an invidious task,
and should never be attempted, except on the clearest evidence, founded upon a far
more perfect knowledge of their history than we at present possess. I shall merely
indicate a doubt where any may exist, and leave the solution of the problem to
future investigations.

Except in the number of the joints of the antennae, Sacium differs but little
from Arthrolips ,- in all other respects its anatomy presents only such modifications
as might be expected to occur between species of the same genus. Among the
species of Sacium a very great difference exists in the length and shape of the joints
of the antennte ; in some species they are short and transverse, but between the
two extremes of variation every intermediate grade can be found.

dissected the organs of its mouth, and, with the single exception that the pro-
sternum is unusually short, can find no difiference in any respect from the most
normal type of Saciion.

Legs rather long and slender, rufous.

Under parts pieeous or rufescent, moderately and distinctly punctured.
Differs from all other sj^ecies in the attenuation of the front of the thorax, and

generally of the extremities of the elytra.
Habitat, Central America. Found plentifully in Vera Paz and many parts of

Guatemala, Mexico (Salle).

This species is subject to much variation in colour ; some examples are black,
with merely the front of the thorax pellucid white or yellow, and present no vestige
of the medial fascia on the elytra ; while others may be described as rufescent, with
dark markings on the thorax and elytra ; but between these two extremes every
intermediate variety occurs. All these varieties are, however, perfectly consimilar
in form and sculpture, and may be distinguished from the other fasciated species
by the peculiar attenuation of the front part of the thorax ; this character is per-
sistent throughout the verj- extensive series of specimens collected by Mr. Champion,
and appears sufficient to justify the claim of S. Oberthuri to be considered a distinct
species.

It is very difficult to decide with any amount of certainty between local races
and true species ; in Sacium, for instance, and many other genera, groups of
so-called species occur which bear a family likeness to each other strong enough to
cause a doubt as to their actual specific distinction. These may be, and probably
are, local forms of but one true species ; nevertheless, to regard them as species of
the present epoch for all descriptive or systematic purposes seems to be a course
less liable to error than to attempt to trace them back to some conjectural primi-
tive stock.

Obs. — There appears to be a great diversity of opinion regarding this species ;
owing to a want of care in determination, or perhaps from still greater carelessness
in affixing labels, I have found S. pusillum represented in various collections l)y
examples of the following extremely dissimilar species, viz. S. Damryi, S. densatum,
S. latum, Artltrolips humilis, Scricodcrus lateralis, Anisom. Revclierii, &c. In the
collections of M. de Marseul, M. des Gozis, and Herr Reitter the exponents of .S'.
pusillum are uniform, and I have followed their guidance in my own description of
the species.

S. ochraceum; but there is an immature specimen among those of S.flaviventre.

Except its ten-jointed antennje this genus possesses no structural character by
which it may be distinguished from Sacium. In many species of Arthrolips the
antennae are very small and short ; this fact, combined with the close manner in
wbicb they are concealed in the cavity of the prothorax, renders the operation of
extending the antennje both difficult and hazardous, and when they have been
extended, or more generally broken off, the articulations of the funiculus cannot be
correctly counted without the help of a very high magnifying power, so that it
cannot be a matter of surprise that its species have often been placed in the
preceding genus.

This species differs so much from any other Arthrolips that at first I believed it
to be generically distinct ; but after a careful examination of its anatomy, I have
been unable to discover any character by which it can be distinguished from
Arthrolips, except that its maxillary palpi are much broader in proportion to their
length than is usual in that genus.

Meioderus bears a superficial resemblance to the Corylophina, but belongs
jiroperly to the Saciina on account of the narrow form of its head, and the character
of its maxilbiry palpi and mandibles, as well as the length of its tibia^ and tarsi.

From Aithrolips, wliicli it resembles in the shape and number of the joints of
its aiitennie, Meioderus can only be distinguished by the general form of its body,
and by the very peculiar shaiie of its maxillarj' and labial palpi ; the former of
these IS abundantly conspicuous without dissection.

The short anterior coxae and the organs of the mouth prove that Meizoderus
belongs to the Saciina ; the maxillary palpi are the only parts visible without
dissection, but these form a distinctive tribal character. From Arthrolips, which it
resembles in the number of the joints and general shape of the antenuse, this genus
is distinguished by the large size and broad shape of its head, its large and broad
thorax with the hinder angles produced and enclosing the shoulders of the elytra.
These last named characters also indicate a lead towards the Sericoderina.

Tribe III.— Sericoderina.

Their truncate elj'tra and elongate posterior angles of their thorax readily
distinguish the Sericoderina from the other tribes of this famih', and the two
genera which it contains may be known from each other by the number of the
joints of their antennic.

All the species of both genera resemble the Trichoptenif/idce so much in outward
appearance that they can only be superficially distinguished from them by the
antennjB and position of the head.

Sericoderas is the most universally distributed genus of the Cori/loplridie ; its
species have been found in every country of both hemispheres into which entomology
has yet penetrated. But it is very difficult to determine between true species (or
rather the conventional species of science) and local races, and on this account
among those described in the following pages some may eventually be found to
belong to the latter category.

This species appears to be truly cosmopolitan. I can find no sculptural
difference between the European specimens and those which I have received from
South Africa, Japan, Australia, New Zealand, the Atlantic Islands, America, and
other places; and it is, I think, doubtful whether S. piihi]n'rtnis, S. palUdulus, and
.S'. lattts are not extreme local varieties of this species. But as these exhibit
considerable diversity in the form of the body and length of the antenniE, I have
separated them from .S'. lateralis.

Tribe IV.--Corylophina.

There is considerable diversity in the fonn of the thorax among the genera
which I have placed in this tribe. In some of them the posterior angles are pro-
duced after the manner of the Seriiodrrina, but all differ from that tribe in having
entire, not truncate, elytra. They vary very much iu the number of the joints of
the antennae, but among the Corylophidce this can only be regarded as a generic
character.

This genus, which appears to be exclusively confined to the Atlantic Islands,
presents in the form of its thorax and pubescent surface of its body considerable
resemblance to the Sericoderiua ; but more properly belongs to this tribe on account

127

of the shape of its elytra, aud thus becomes a connecting link between the two
tribes. From the other genera of Corylophina, Microstagctus may be known by its
pubescent surface, and by the remarkable shape of the joints of the anteunfe.

This genus differs much from any other iu its superficial appearance, and is
especially distinguished by the peculiar formation of its eight-jointed antennse, of
which the second joint seems to form part of the funiculus, and is, contrary to the
usual dimensions, smaller than the third ; the third articulation seems to represent
the more normal three or four joints, but I cannot perceive in it any vestiges of
division, even when immersed in Canada balsam, and examined under a quarter-
inch power ; all the subsequent joints are of the usual Corylophide type. I did not
venture to dissect the mouth of this unique specimen, but both the labial and
maxillary palpi clearly exhibit the apical joint broad and rounded as in the genus
Conjlophus.

body, the large size of its thorax, the long incurved anterior tibia, and the peculiar
formation of its eight-jointed anteunte.

the species are all European, but seem confined to its southern regions.

Corylophm was originally founded by Mr. Stephens on C. Cassidoides, and the
species which I have retained in the genus are those which resemble that insect in
their nine-jointed antennae, and elongate posterior angles of the thorax, and
especially in the extraordinary formation of the maxillary palpi, of which the
second joint is furnished on its outer extremity with a series of very long coriaceous
appendages, exactly resembling the rays of a fan, and arranged in a preciselj'
similar manner. I cannot imagine the use or purpose of this wonderful apparatus,
unexampled in any beetle I have ever examined. It attains the greatest develop-
ment in C. tectiformis, but is equally distinct, although of smaller dimensions, in
the other species.

This genus differs from Cori/hphns in both the shape and number of the joints
of the antennse, and also in many parts of its anatomy. All the species yet known
belong to the warmer regions of the earth ; with few exceptions they inhabit the
Western Hemisphere, and may be regarded as the antitypes of the Old World
Corj'lophi. In outward appearance they resemble the C'DccincUidte so closely that
some species have been described by more than one author as members of that
familj' ; but in all these cases the antennre and organs of the mouth are of the
most normal Corylophide character.

Some specimens, probably females, are smaller and much jjaler in colour.

In the shape of some parts of its antennffi, and of the lobe of the maxilla, this
species differs very much from the type of Cori/liqiJiodes, but I do not think that
these points are by themselves of sufficient importance to constitute a distinct genus.

his successful researches among the insects of the present family, and those of the
Pxev(loeor]jlo])]ii(he, resulting in tlie discovery of live new genera, and many new
species.

Lewisiiiiii at present contains two species, which may be distinguished, viz. : —

Superficies glabrous ... ... Ceylonicum.

Although the organs of the mouth in this curious genus bear a collective
resemblance to all the other tribes e.xcept the Saciina, I have preferred placing it
in the present tribe on account of its similarity to Cori/lophtis in outward form, and
in its smooth and highly-polished surface. The elongate and acuminate shape of
the anterior portion of its head and the form of the mandibles and labrum are of
themselves sufficient to separate Catopti/.r from any other genus, but the short
dilated tarsi and tlie broad compressed shape of the four posterior tibia; also form
very distinctive characters.

This beautiful and conspicuous insect resembles the species of Corylophus in
the general form, and in the smooth and highly polished surface of its body, and
also in the disposition of its bright crimson markings, which on the elytra are more
or less suffused, leaving only the margins and suture black. C Bowriiuiii is subject
to much variation in both size and colour, some examples exhibiting the beautiful
markings described above, and some being of an almost uniform castaneous colour,
and of a smaller size ; but, as there is no sculptural difference between these forms,
the latter are probably the females, and the former the males of the same species.

Tribe V. — Orthoperina.

In this tribe the head is always more or less visible from above, and in no case
entirely covered by the pronotum. This character distinguishes the Orthoperina
from every other tribe except the Phanerocephalina ; from this they differ con-
spicuously in the subhemispheric shape, and shining surface of their whole body.

The two genera at present known are distinguished from each other by the
number of joints in their anteunte, besides many anatomical differences.

The genus Rlnjpobiiis was founded by Dr. Le Conte in 1852 upon a species
found in America, and described by him under the name of R. marinus in the
Proceedings of the Academy of Sciences of Philadelphia, vi. p. 141. In 1859
M. Duval published (Gen. Col. Eur. ii. p. 236) the description of his genus Moronillus,
containing one European species, M. ruficoUis, an insect evidently congeneric with
the K. marinus of Le Conte. Again, in 1854, in his Ins. Mad. j). 480, Mr.
WoUaston created the genus (Jlceosoma to receive G. velox, a species found in the
Atlantic Islands, and also congeneric with Ii. marinus. From this it is clear that the
priority of nomenclature belongs to Dr. Le Conte, and that his name must be
retained for the present genus. The three sjiecies already mentioned resemble each
other very closely in colour, but may easily be recognized by their size and
sculpture. All the other species are very distinct from these, and from each
other.

In Rhgpobius the head is much less exposed than in Ortlioperus ; from that
genus it also differs in its eleven-jointed antenna, and in many anatomical charac-
ters, of which the extraordinary shape of the mandible is the most remarkable.
The mandibles of Rlu/pobius were so totally unlike those of any genus I had pre*
viously seen, that it was not until I had dissected many individuals that I became
convinced that they were true mandibles ; but since then I have discovered that
mandibles of precisely similar form exist in the genus Catopti/.r, and in some
others.

I feel some hesitation in placing this species in the genus Rlimiohiiis, but since
on careful dissection all the organs of the mouth, especially the extraordinary linear
mandibles, and also the shape and disposition of the various parts of the external
skeleton of the under side, differ in no respect from the corresponding parts of the
most normal s()ecies of lihi/pvhius, I think it better to place it with them than to
create a new genus for its reception.

Legs anterior with the coxie long and ovate; trochanters small, ovate; femora

simple ; tibire often very long and much incurved, abruptly incurved at the

apex with the extremity obtuse ; tarsi rather long, four-jointed, 1 and 2 nearly

equal, much produced on the lower side, 3 very small, 4 long and slender,

claws long, slightly curved, and incrassale at the base.
ititennediaic with the coxse oval, rather distant, tibiae simple, not elongate, in other

respects like the anterior.
posterior with the coxi^ large, suboval, widely distant, iu other respects like the

intermediate.

This genus is distinguished from RItypobivs by the much more evident extrusion
of its head, its nine-jointed antenuie, and in many species by its very long incurved
anterior tibiae. The species of Ortliopems appear to be numerous, and common to
both hemispheres ; but in a state of nature are dillicult to detect, owing to the close

183

resemblance which they bear to the seeils of plants, a resemblance much augmented
by their habit of remaining for a long time without motion. This fact in a great
measure accounts for the paucity of individuals by which many of the species are
represented in collections. A notable instance of this occurred in Mr. Champion's
Central American collections, which contained only six Orthoperi, but these six on
examination jiroved to belong to four very distinct species. All the species of
Orthoperus, and probably many other Corylophidce, seem to be extremely local, and
when one has been discovered, others should be immediately searched for and
captured ; this is often an easy task, but, if neglected at the time, the opportunity
of obtaining specimens may never again recur.

I have used the names "atomus, Gyll.," and "<it<>mariits, Heer," in preference

given by Mr. Marsham are so exceedingly vague and indeterminate, that it would
be confusing to alter our present nomenclature without actual comparison with the
Kirbyan types. — A. Matthews, Ent. Mo. Mag. vol. xxii. p. 107.]

ILihitat, South America, Guadaloupe, Fleutiaux.j

I have copied the foregoing description from Mr. Matthews's note books
because he has retained the diagnosis in tlie epitome of the species of this genus.
But I suspect that the discovery of abundant specimens of 0. perpusiUits in the
West Indies induced Mr. Matthews to sink this name altogether ; especially as he
omitted the name from the systematic list, and also did not leave any description
in his MS. The specimens in his own collection labelled with these two names
seem to belong to the same sjjecies. — [Ed.]

cavities rounded, and rather widely distant.
Pectus with the mesosternum (PL VII., C, fig. 2, d) short and broad ; episterna

deflesed and inconspicuous ; epimera excessively large, extending round the

whole outer side of the coxal cavities ; coxal cavities rounded, and very widely

distant.
metasternum (PL VII., C, fig. 2, g) transverse, very broad, extending to the sides

of the body, posterior margin slightly rounded between the coxje ; episterna

and epimera very narrow, coriaceous, almost rudimentary, entirely concealed

by the elytra.
Venter composed of six segments, the first long and large, the rest much shorter,

equal to each other in length, and the apical entire.
Legs (interior with the trochanters acutely conical ; femora robust, simple ; tibiae

simple, slightly dilated at the apex ; tarsi three-jointed, the two basal joints

almost equal in size, deeply bifid ; apical joint elongate and rather slender ;

claws moderate, dentate at the base beneath.
intermediate and posterior like the anterior.
Coxte all rounded, and gradually becoming more remote.

The same reasons which induced me to separate Pluenocephalus into a distinct
subfamily prevail with still greater force in the case of the present genus ; indeed,
the shape of the palpi is the only character in which Aphanocephalus bears any

'200

resemblance to the CorylophiJa. Its antenu.-c are I'ormed on an entirely different
tj'pe, and tlieir small solid club is not vertically doubled back upon the funiculus,
as it is in all the Cdrt/lophicLe. The maxilht are three-lobed after the fashion of the
Trii-liopteriiiiiila- with this small difference, that the outer lobe is not on the same
level with the other two. The wings in shape and neuration resemble those of the
Silphidie, but are wholly unlike the Corijlopliithe. The tarsi, examined in Canada
balsam,- present no vestige of the small penultimate joint universal among the
Coryl<)})huhe, but are clearly three-jointed. And in the excessive development of the
mesosterual epimera Apliaiwccphultis again resembles the Trichopteryfi'uhe.

The three-jointed tarsi and general superficial appearance of this genus
reminds one of the CocciucUidte, but the resemblance extends no farther, and can at
the most but form an indication of its systematic position.

On these grounds I have determined to separate Aphanoccphaliis from the
Corylophidte, and to place it next to the Cuccincllida ; to which the form of all its
sj^ecies and the colour of some among them bear a well-marked resemblance.

The shape and colour of this beautiful insect indicate the affinity between the
present family and the Coccinellidce. In outward appearance it is so unlike the
typical Aphauocephali, that I supposed it would belong to a distinct genus, but on
dissection I found that the organs of the mouth were in every respect precisely
similar to those of .1. heniispliericus, and that it as perfectly resembled that species
in every part of its external skeleton ; the same excessive development of the
mesosternal epiincra, and the same rudimentary condition of the metasternal cpisterna
and epimera existing in both species.

Of this remarkable insect there are many specimens in the collection of the
British Museum. In outward appearance it is wholly unlike ^l^j/faHoccjj/x/^K*,- but
I was led to suspect that it might belong to that genus by the similarity of the
proportions of its antennae, and therefore minutely examined the anatomy of the
external skeleton of its under side, and dissected the organs of the mouth. In all
these particulars the resemblance is so perfect that the diagrams of the anatomy of
A. hciiiixphcriciis fully represent the corresponding parts of the present species.
The most characteristic of these arc the great size and lateral dilatation of the
epistoma ; the great development of the lingua ; the round anterior coxal cavities ;
and the prodigious enlargement of the mesosternal epimera.

The genus Phainocephalus was formed by Mr. Wollaston for the reception of a
singular insect found in Japan by Mr. Lewis ; singular in every sense of the word,
since only one specimen has hitherto occurred. Although he placed Phcenocephalus
among the Conjlophixlm, Mr. Wollaston seems to have had much doubt as to
whether it really belonged to that family. It bears, indeed, a striking resemblance
to them in its outward appearance, but throughout its whole anatomy there is no
character which truly agrees with the normal type of the Coriilophid(e, while many
are totally diverse. For the same reasons it is equally impossible to associate this
genus with ApJianoeephalus ; and therefore to separate Phcenocephalus into a distinct
family appears to be the only course to pursue without violating the fundamental
rules of division.

Although I was fortunate enough to succeed in dissecting, without injury to
the appearance of the specimen, the greater part of the organs of its mouth, yet,
as this example is the only existing exponent of the genus, I did not attempt to
interfere with the labrum or mandibles ; the former is described from merely
superficial examination, and the latter altogether omitted.

SPHrERIID.l^].

The Hpluerikhe form a small and somewhat isolated family exhibiting no
special affinity to any other group except the Sphteridiidte, and to them only in
outward appearance and in the subsolid capitulum of their anuennae. Its true
systematic position has therefore been a fertile cause of perplexity ; but since their
elongate and free, or prominent anterior coxeb, together with the characters above
mentioned, bear a strong reseml)lance to the corresponding parts of Ccrcijon, it
would seem most natural to place this family next in succession to the Splucridiidce ;
to which family also the life habits of Spluerins, as far as they are known, appear
to be very similar. .S'. ncaroides, the best known and the most common species of
the genus, has always been found at the roots of herbage, or in moss in boggy
places.

Although the species of Spluerius are not often seen in collections, I believe
that in nature they are by no means rare. I have received them from Europe,
from many parts of North America, from Central America, Asia, and Northern
Africa, as Well as from three localities in this country. Thus they seem to be
distributed throughout the regions north of tlie Equator in both hemispheres ; but,
as far as I know, they have not hitherto occurred on its southern side.

From other families the Splueriid,e may be distinguished by their comparatively
large and prominent head, their peculiarly formed antennae, the enormous lamina-
tion of their posterior coxse, and the unequal length of their ventral segments.
