INTRODUCTION.
Tue three Families of which this, the Seventh Volume of the Coleoptera, treats—the
Erotylide, the Endomychide, and the Coccinellide—form a not unnatural assemblage
of genera, though at first sight, and indeed on closer examination, they present con-
siderable divergence in points which have been usually regarded as of great importance
in Classification. Such is the tarsal structure, which in the first of these families is
pentamerous, but very much modified, becoming in the less specialized genera
tetramerous. In the second family—the Endomychide—the foot is tetramerous, but
again modified; it is the basal joint which becomes obsolete, the fourth joint of
the tarsi being, as in the Erotylide, a mere node at the base of the fifth or claw-joint.
In the Coccinellide this nodal joint disappears.
Notwithstanding this very important difference, which is without doubt correlated
with the habits of these insects, there are too many points of agreement to be passed
over. One of these is the presence of certain impressed lines on the metasternum and
on the basal abdominal segment, which are clearly in the higher groups, as the
Languriides and the Erotylides, the rudiments of original fossettes or broad depressions
for enabling the femora to lie closely retracted, with the tarsi and tibie shut up like a
pocket-knife. These fossettes are retained and developed in the great majority of the
Coccinellide, or become rudimentary in the Languriides and Erotylides, which have
the legs less retractile, and are quite lost in the Endomychide and some genera of the
other two groups.
The sole of the foot, like that of the Phytophagous section of Coleoptera, is broad
and spongiose in the great majority of genera, two joints (Coccinellide), or three
(Erotylide), being bilobed, flattened beneath, and furnished with papille, which are
adapted for obtaining a firm hold on plants; this character, through the phytophagous
Coccinellide, affords a clue to the phylogenetic connection of these families with the
true Phytophaga. The Aphid-devouring instinct of the more highly developed
Coccinellidee would easily be explained on the view that certain phytophagous beetles
obtained and preferred this food while pursuing their original habit of life, and
possibly when the Aphides or Coccide were so abundant that they could not be avoided,
V1 INTRODUCTION.
It is, I think, a significant fact that the Erotylide and Endomychide still prefer, or
are almost always associated with, the highly nitrogenous pabulum afforded by fungi.
With regard to the distribution of these families so much is new that it has very
greatly modified our earlier ideas, and so many new facts no doubt remain to be
discovered that hasty generalizations must not be drawn. When Lacordaire wrote
his Monograph of Erotylide, it was thought that the New World was very plainly
the home of these beetles; but subsequent collections from the Eastern hemisphere
showed that these regions were possibly as well stocked. The numerous species of
this family brought to notice in the present work have tended to restore the apparent
supremacy of the Western Continent, but I believe it will prove to be more apparent
than real.
Taking the Languriides, Chapuis, in the ‘Genera Coleopterorum,’ notices two
genera only; Crotch, in his ‘Revision,’ admits fifteen; and in my ‘ Classification,’
published in 1887, I found it necessary to propose thirty-two, while two or three more
have since been added. The number of genera enumerated in this volume from
Central America is fourteen, while of the sixty-nine species recorded, fifty are treated
as new. It is probable that an equal number of species exist in both hemispheres.
Of the true Erotylide (the Dacnides, Triplacides, and Erotylides) fifty-six genera
are recognized by Crotch, and fifty-seven in the Munich Catalogue, with 1011 species
(omitting Helota and Orestia, the last-mentioned being an ordinary member of the
Phytophaga). Thirty-five genera are found in the New World, five only of which are
common to both hemispheres; of these latter, Husxestus, Dacne, Triplax, and
Cyrtotriplax (=Tritoma) are feeble forms whose relations are not yet well defined,
and are, moreover, indicative of the northern regions of the globe. It is therefore to
be observed that only one genus of well-ascertained position, viz. Megalodacne, is
represented in both hemispheres. From the region under investigation we have
recorded thirty-two genera and 213 species, nine genera and 104 species being treated
as new. ‘To compare the ascertained Fauna with that of the Old World it would
be necessary to take into account a large number of new genera proposed by myself
and others since the publication of the Munich Catalogue and of the Supplement to it.
The only conclusion, I think, we can at present draw from these data is that while a
very large number of new species remain to be discovered in all parts of the world,
the predominance, both of genera and species, though not large, is in favour of the
New World, and that the forms of this highly developed family of beetles are
INTRODUCTION. vil
largely endemic. The Endomychide, which I regard as also being a highly evoluted
family, but as containing more primitive and generalized genera than the Erotylide,
bear out this view.
The number of genera of the family Endomychide, including the additions to the
Munich Catalogue, may be roughly taken as sixty, and the described species as 480.
In the volume now completed the genera recorded are fifteen, with eighty-one species,
of which four genera and thirty-nine species are new. I have before recorded my
conjecture that the smaller and more hairy species, as those of the large genus
Stenotarsus, represented a more primitive less evoluted form, and these are found in
all parts of the world.
The large family of the Coccinellide presents more difficulties on the subject of
distribution, from their being, as it appears to me, taken as a whole, of a more
generalized type than the two preceding families.
What strikes one, on studying this group with attention, is the very feeble and
trivial characters on which the genera are based, and yet that better ones cannot be
found. And this appears from the varying opinions of classifiers as to their adoption
in their systems. Thus, while Crotch admits 137 genera for 1340 species, only
100 genera are retained in the Munich Catalogue for 1444 species.
For Central America, as recorded in this volume, 239 species are placed in forty-
three genera; and while of this rather limited number 108 species are apparently
new, I have only-ventured to propose three new genera.
But the species of this family rather readily divide into two sections, according as
they are smooth or hairy, and still more so if we take the larger and more important
portion of the latter which are phytophagous, and have the mandibles retaining the
form adapted for that kind of food.
One can hardly avoid the conclusion that the Hpilachne are derived from the
Phytophagous stirps, not only on account of their food, but of their very close
resemblance in many instances to Cassidide, some very closely resembling Chely-
morphe, and others having the metallic lustre of so many of this latter family; and
the singularly convex and inflated form of the elytra in the Coccinellide, modified,
but present, in the #githi and true Erotyli, having, as I think, its counterpart in the
gibbous and elevated forms of Cassidide. It is not only in their food that the
Vill INTRODUCTION.
Epilachne have been conservative, but in the evolution of their structure also, as
they belong to a plain generalized type, perhaps best adapted for living under
varying conditions with very little modification; and, like the genus Stenotarsus,
Epilachna is distributed in almost every part of the world, below the sixty-fifth parallel
of North latitude. It is well known how this genus predominates in the Eastern
hemisphere, and how the species there are so little differentiated that it is very
difficult to distinguish or classify them. |
The higher forms of the family, from their black-and-red-spotted bodies, and from
having to seek their aphidean food on the surface of plants, must be peculiarly
attractive to their enemies. This brilliant livery seems retained and even developed
from their ancestry ; but it is compensated for by two very important facts—(1) a
secretion, distasteful, as it seems, to birds, or lizards and other reptiles; (2) a high
power of contractility, enabling them to drop on the slightest alarm. It is for this
last-mentioned purpose that the fossz, so usual on the basal segment of the abdomen,
seem to have been produced, the rudiments of which (now of no use) are visible in
the Erotylides and Languriides ; and though these rudiments are rarely seen in the
Endomychide, it is a significant fact that in the genus Panomea, which so remarkably
mimics various Coccinellide, as nearly always to be taken for one even by Coleopterists,
the structure is retained, as well as the round and convex form and the type of
marking.
An immense amount of material has passed through my hands during the publi-
cation of this volume, and I may especially call attention to the vast number of
specimens due to Mr. G. C. Champion’s careful collecting, especially in the small
and obscure species usually neglected.
There still remain a considerable number of minute and obscure insects unclassified,
some of which, without doubt, pertain to the group here treated, but it was thought
better to close the work. Many specimens of the genus Hapalips (Languriides) were
unfortunately mislaid, and cannot now be included, but must be described or noticed
elsewhere. It is obvious, however, that every collection of any extent will for some
time to come contain new species.

BIOLOGIA CENTRALI-AMERICANA.
ZOOLOGIA.
Class INSECTA.
Order COLEOPTERA.
Fam. EROTYLIDZ.
Subfam. LANGURIIDES.
The “ Languriides,” as a subfamily of the Erotylide, may be termed aberrant—not
that they are separated from the rest of the family by any very trenchant character,
but on account of their remarkably homogeneous elongate form and generalized struc-
ture. A proper classification of them has not hitherto been attempted ; the described
‘species are, however, now becoming so numerous that some further division of the
group into genera has been found necessary, and an attempt to express their mutual
relationships will be found in a paper by myself in the ‘ Proceedings’ of the Zoological
Society, 1887, pp. 358-362. The family is widely distributed, being found in the Tropics
generally, in the Nearctic Region and Japan, in North Australia, and at the Cape of
Good Hope. No species occur in Europe, New Zealand, or Madagascar, nor do any
extend far north or south of the Tropics.
GONIOLANGURIA.
Goniolanguria, Crotch, Cistula Ent. i. p. 895 (1876).
Type Languria latipes, S. Saunders, Trans. Ent. Soc. Lond. i. p. 149, t. 14. f 1 (1834).
This genus was established by Crotch.and formulated as follows :—“ Elytra produced at
the apex, slightly divaricating, denticulate; thorax margined at the base, with a small
stria on each side; head with the sides angulated for the very large mandibles; occiput
with one stridulating series; antenne with a five-jointed club; tarsi very broadly
dilated.”
In such a difficult matter as the formation of genera in this group has proved (so
difficult that the late Baron von Harold abandoned it in his paper on the Hastern
forms), it will easily be imagined that the formula quoted above is wholly insufficient.
BIOL. CENTR.-AMER., Coleopt., Vol. VIL, September 1887. B*
2 EROTYLIDA.
Crotch’s second species (as he himself points out) differs; and as a fact the specimens
included under the name latipes, Saund., in his collection, not only, as he surmised,
belong to two or more species, but must be placed in different genera.
Five or six of these specimens have long front legs and roughened femora and tibie
of both the front and middle legs, and are males, being so far equivalent to the species
here described under the new generic name Dasydactylus; while the typical example
(which appears to be the only one correctly identified with Languria latipes, Saunders),
from which Crotch drew his diagnosis, differs. wholly from the others in many
respects. In this specimen the head is not symmetrical, and the soles of the three
basal joints of the tarsi, and notably the front pair, are clothed with close, short, and
squamose scales without sete or hairs; while in the species of the Dasydactylus type the
tarsi are more or less hairy or setose, and the front pair in the male sex has the basal
joints not only widened, but often quite villose. Thus the sexes are more differentiated
in the species of the Dasydactylus type; but it is especially noticeable that, with certain
exceptions, the species of the New World belong to the latter section, and that the
majority of the genera which exhibit the spongiose form of foot are from Eastern
Tropical Asia.
My. Fowler while pointing out, in the Trans. Ent. Soc. Lond. 1885, pp. 381-383,
the important characters that exist in the structure of the head, has very naturally
been misled by this want of discrimination of the sexes, for his remarks about the
clypeus, or as I here term it the epistoma, apply to the Dasydactylus-looking males, and
not to the Languria latipes. It is therefore necessary to give other characters by which
the species allied to this type may be correctly assigned to their proper place :—
Goniolanguria (Crotch). Tarsi antici valde dilatati, subtus spongiosi fere velutini, supra
pube molli tenuiter vestiti maris hirtuli; epistoma antice angulatum haud vel leviter
excisum.
1. Goniolanguria (?) palmata.
Nigro-snea, nitida, subtus cum pedibus nigro-picea; capite prothoraceque fere glabris, hoc oblongo-quadrato ;
elytris obsolete punctato-striatis, interstitiis minute subseriatim punctulatis, apicibus truncatis, leviter
denticulatis. Long. 15 millim. ¢.
Mas abdominis segmento ventrali apicali ad apicem in medio dense nigro-pubescente.
Hab. Panama, near the city (Champion).
Fem. (2?) abdominis segmento ventrali apicali minus dense pubescente.
Hab. Guatemata, Purula (Champion).
The general characters of the species now described agree pretty closely with those
of the type of Goniolanguria, Crotch; the head is not quite symmetrical, the left
mandible being larger than the right-hand one, and the gena being proportionately
swollen to afford it a basis; a stridulating file is found when the head is bent forward
so as to withdraw the crown from the thorax; the front feet in both sexes (assuming
GONIOLANGURIA.—TRAPEZIDERA. 3
the single example from Purula to be the female of the same or a closely allied species)
are very wide, their basal joint as wide as the second, not hairy but with spongy soles
and finely pubescent above; in neither sex do the femora show any tubercles or
roughening, and the apical segment is not excised but bears a thick hairy patch. The
elytra taper more strongly than in Trapezidera or Teretilanguria, and their apex is
truncate with many denticules. The antenne have a distinct five-jointed club; the
antennal sockets are large and open, but not so explanate as in the type of the genus;
the ocular striola is deep and straight, divaricating behind from the canthus; the
epistoma is angular, entire at its apex, marked by a vague impression from the rest of
the head; the labrum appears to be membranous, very much reduced, but set with
long shaggy fulvous hairs.
The head in the hypothetical female from Purula is more strongly punctulate than
that of the Panama male type.
TRAPEZIDERA.
Trapezidera, Motschulsky, in Schrenck’s Reisen und Forsch. Amur-Lande, ii. p. 244 (1860) *;
Crotch, Cistula Ent. i. p. 393 (1876). .
Motschulsky can scarcely be said to have characterized this genus; it is merely a
name suggested for species of Zanguria with the apex of the elytra denticulate. Crotch
separates Teretilanguria for those species which have a double stridulating file on the
crown, and Goniolanguria for those which have a single file together with the apex of
the elytra truncate. Both these genera are good, and are further characterized here.
I find it necessary also to separate T. longicollis, Motsch. (= prolongata, Crotch, a name
adopted from Chevrolat’s collection). This will leave for Trapezidera certain species
which have the thorax trapezoidal and the elytra with six or seven denticules at the
apex; it will be represented by 7. wnea, Crotch, as a type. I think it probable that
T. angusticollis, Motsch., and some other of this author's species are identical with
T. enea; but the identification of these species does not seem possible from the
descriptions.
I give a fresh definition of Trapezidera:—Elongate, but not more so than usual ;
antenne with the terminal four joints forming a flat and pubescent club, the seventh
joint not nearly so wide as the eighth and not so pubescent; orbital striola scarcely
leaving the canthus, but little produced backwards; prosternum flat and horizontal,
with a deep fovea on each side of the intercoxal process, its apex a little emarginate ;
shoulders of the elytra the widest part; apical ventral segment punctured and pubes-
cent, not laterally excised (?); tarsi scarcely hairy in either sex, nor wider in the male
than in the female.
* Motschulsky (Etudes Ent. 1859, p. 66) had already used the name 7’rapeziderus for a genus of Staphy-
linide ; I, however, follow Crotch in retaining Trapezidera.

1. Trapezidera snea. (Tab. I. fig. 3.)
Trapezidera enea, Crotch, Cist. Ent. i. p. 893°.
Languria ahena, Sturm, in litt.
Hab. Muxtco!, Guanajuato, Parada, Toxpam, San Andres Tuxtla (Sallé), Zapotlan,
Colima, Cordova, Morelia in Michoacan (Hoge); Guatemana, Calderas, San Juan in
Vera Paz (Champion); Nicaragua, Chontales (Janson); Costa Rica, Cache (Rogers) ;
Panama, Volcan de Chiriqui (Champion).
This species (which I use for the type of the genus in default of knowing 7. angustv-
collis) has the head strongly and closely punctured; the orbit of the eye forming a
ridge, the ridge prolonged round the base of the antenne in front, and divaricating a
little from the eye behind, but not continued further back than the eye itself. The
thorax is not very convex, rather depressed behind, a little angularly prominent in the
middle of its base, the base margined; the basal striole only indicated by a puncture
on each side; its disc closely and rather distinctly punctate. The elytra have the strie
fine and very thickly punctured; with numerous punctures, of about equal size, in the
interstices, so that the punctures appear confused with the strie; they are twice as
wide at the base as at the apex. The body beneath and the greater part of the legs
are pitchy; the breast and abdomen almost smooth and shining; the prosternum is
wrinkled, its intercoxal process margined by a line which becomes deeper behind so as
to form two fosse; the apical segment of the abdomen is punctured.
Crotch has apparently compared this species with his 7. chalcea. The general form
and size are very much alike in the two species; but the latter has a smooth head and
roughened front tibie, and pertains to the genus Dasydactylus as here defined ; 7’. wnea
is, moreover, more distinctly brassy in colour above. It appears to be a commoner
species in the State of Panama than further north, and I have only seen two specimens
from Guatemala and one from Nicaragua.
The specimen figured is from Cordova. The examples from this locality have the
head and thorax more coarsely punctured than those from other Mexican localities.
2. Trapezidera semiotina. (Tab. I. fig. 4.)
Ferruginea, nitida; prothoracis limbo laterali lineaque mediana, scutello, elytrorum margine reflexo, genibus,
tibiis, tarsis, trochanteribus antennisque, nigris; elytris crebre subtiliter punctatis, sutura postice cum
apice nigro-fuscis. Long. 12-17 millim. 9?
Hab. Mexico, Panistlahuaca (Sal/é); Guatemaua, Rio Maria Linda (Champion).
Wider across the shoulders and more strongly narrowed to the apex than 7. enea;
the elytra also having their apex almost truncate, though only the extreme apex, which
bears four or five distinct denticulations, is straight. The antenne have the club narrow
and composed of five joints, while the preceding or sixth joint is nearly as wide as the
seventh. This species therefore differs from the generic formula of 7. @nea, and may
possibly have to be separated ; it is not, however, a Zeretilanguria, the ocular striola
TRAPEZIDERA. 5
being simple and straight, the thorax finely (but distinctly) margined at the base, the
scutellum transverse, and the elytra closely and irregularly punctured. Iam unable to
distinguish the sexes, although having only seen four specimens it is not possible to
assert we have both sexes present. The prosternal process is wide, slightly raised
above the plane of the front part of the prosternum, very even, and finely margined and
widened at the apex, the apex truncate in a straight line. The apical ventral segment is
slightly pubescent, scarcely punctured, blackish at the tip, and only a little acuminate.
The ferruginous colour with parts black mentioned in the diagnosis is amply sufficient
for the recognition of 7. semiotina, and give this species a very Elateroid look. Three
of the four specimens are from Panistlahuaca.
3. Trapezidera lateralis. |
Castaneo-rufa; antennis, genibus, tibiis tarsisque nigris; elytris extus et ad apices ceerulescentibus, punctato-
striatis, interstitiis subrugulosis et confuse punctatis, apicibus leviter denticulatis; capite prothoraceque
fere glabris. Long. 8 millim.
Hab. Muxico, Cordova (Hége), Toxpam (Sallé); British Honpuras, Belize (Blan-
caneaux) ; GUATEMALA, San Geronimo, Chiacam, San Juan in Vera Paz (Champion).
Head, thorax, body, and base of the legs castaneous, almost blood-red; antenne,
apical half of the femora, tibie, and tarsi black; elytra steel-blue, with the suture and
usually the greater part of the disc castaneous-red. ‘This species is very difficult to
place, as hitherto I have not been able very satisfactorily to distinguish the sexes. The
prosternum is broad and smooth, narrowly margined, with the apex truncate and gently
emarginate; the femora are not much thickened, nor apparently at all roughened.
The only character which I can find for separating the males is, that in some specimens
the tarsi appear wider than in others, but not decidedly so, nor are they very hairy.
The apex of the elytra is faintly denticulate. ‘The apical ventral segment is blackish at
its tip and sparingly pubescent. Taking the whole of its characters, I think at
present this curiously-coloured species had better be placed with Trapezidera wnea and
T. semiotina. About twenty specimens in all are before me. It is the “ Languria
lateralis” of Sallé’s collection.

CAMPTOCARPUS.
Trapezidera (pars), Crotch, Motschulsky.
Type Trapezidera longicollis, Motsch. (= prolongata, Crotch).
Body very elongate; thorax with a distinct and acuminate basal lobe; elytra denticulate at the apex;
antenne with their seventh joint obtrigonal, internally acuminate, evidently wider than the sixth, and
forming the commencement of the club. Anterior legs of the male with their tibia sinuate, much bent
inwards and widened at the apex, the widest part inwardly angular and compressed and pubescent.
Prosternum with the intercoxal plate nearly flat, widened, and widely emarginate at the apex.

Very elongate and subcylindrical; varying in size from eleven to twenty-four milli-
metres; of a uniform brassy-green colour. Legs and underside nearly black. Very
finely punctured above, and finely alutaceous. Head with scattered punctures, which
are thicker and deeper in front; labrum short but distinct; from the antennal socket
a striola passes close to the orbit, but diverges from the eye behind, and extends hardly
so far back as the eye itself. Antenne not so long as the thorax; the third to the
sixth joints elongate and subequal, smooth; the seventh joint triangular, narrower and
less pubescent than the succeeding four, which form a flat club. Thorax elongate,
narrowed in front, the basal median lobe acuminate, the surface very finely alutaceous.
Elytra widest a little below the shoulder; evenly narrowed to the apex, where they
divaricate a little, and are each armed with about seven or eight serrate teeth. Front
legs of the male long; their tibie sinuous at the base, and below the middle abruptly
bent inwards, angularly widened and compressed at the tip; their tarsi with the three
basal joints widened and very hairy, these joints in the female narrower and less hairy.
In certain males the margin of the elytra is expanded below the middle. .
CAMPTOCARPUS.—TERETILANGURIA. 7
It is singular that Crotch should have omitted any notice of the remarkable sexual
character in this species, as in his collection are two or three males; and Motschulsky
has in his description of Trapezidera longicollis expressly mentioned this character :—
“ jambes antérieures allongées, courbées, et dilatées 4 ’extrémité dans l’un des sexes,
cuisses renflées et un peu arquées.” I have no hesitation in the application of
Motschulsky’s name; his specimens were only of medium size and from Nicaragua.
The diagnosis given by Crotch is altogether too meagre. JI have more than two
hundred specimens of this insect before me, very many of which are from Cordova:
except in length, it does not appear subject to variation ; a few have obsolete sculpture
or punctuation on the thorax, and small males have the tibiz less strongly bent.
MERISTOBELUS.
Body shaped as in Trapezidera, but the elytra with their apices acuminate and divaricating, not denticulate.
Head with the epistoma not well defined; a space between the antennal socket and the eye; ocular
striole straight, not well marked; stridulating carine small, double, hidden by the front of the thorax.
Thorax trapezoidal, without basal strie; the base with a fine marginal line, and scarcely produced in
the middle. Scutellum obtrigonal. Legs not very long, their femora thin, not roughened; tarsi slightly
hairy beneath as in male Teretilanguria. Prosternal process wide, not margined nor foveolate, truncate at
the apex, very even. Ventral apical segment of the abdomen rounded at the apex, not punctured ; hairy
only at the sides. Apex of the elytra not hairy beneath. Sex uncertain ( 9 ?).
I place in this genus a single species from Mexico. Two examples only, both
possibly females, of this are known to me.
1. Meristobelus forcipatus.
AMneus ; capite distincte parcius, prothorace obsolete crebrius, punctatis; elytris obsolete punctato-striatis, cum
apicibus acuminatis, divaricatis, et paullulum reflexis; corpore subtus glabro; pedibus piceis, geniculis
tarsisque nigricantibus. Long. 13 millim.
Hab. Mexico, Chinantla (Sal/é).
Resembling, but rather smaller than average specimens of, Trapezidera cnea, but at
once distinguished by the curious bifurcate apices of the elytra. The antenne are
bluish-black, with their club formed as in Trapezidera, the four terminal joints duller
and much wider than the seventh. The head does not present any striking characters ;
the epistoma is hardly marked by a faint straight impression; the antennal sockets are
deep, the ridge above strong (above the eye the ridge is very little raised). The whole
insect is narrower before and behind. ‘The tarsi are of average width, rather wide if
the examples are females (there is no means of judging of the sex without destroying
the specimens); finely pubescent above, and with short matted hairs beneath.
TERETILANGURIA.
Teretilanguria, Crotch, Cistula Ent. i. p. 394 (1876).
This genus was proposed by Crotch for a large and common South-American insect
described by him as Zeretilanguria kirschii, with which Languria basalis, Guérin (Icon.
8 EROTYLIDA.
Régne Anim. Ins. p. 314) is congeneric. In his very short diagnosis of the characters
the only ones of importance are that the thorax is not margined at the base, and that
the head bears “two stridulating plates.” The other characters mentioned are common
to Trapezidera and Dasydactylus, and the last-named one does not seem satisfactory, for
certain Dasydactyli have minute files on the base of the head. Nevertheless the genus
is quite a natural one, and possesses good characters, both in the sulci near the eyes and
in sexual distinctions; I give a fresh definition :—
Head with the epistoma transverse or nearly square, quite distinct.from and produced
well in front of the antennal fosse; labrum membranous, only ‘corneous at its front
edge; orbital striole deep and sulciform, double behind the middle of the eye, the
orbital canthus raised behind. Antenne short, their club elongate; the seventh joint
smaller than either of the four apical ones. Thorax usually trapezoidal and very
shining ; slightly more convex, and with the front angles more reflexed, in the males ;
the base without marginal line. Tarsi (especially the front pair) spongy beneath; with
short cilia, and fine hairs above. Front femora of the male subclavate, thickened
outwardly, and on the inner side finely sulcate, or with very fine tubercles; they are
also a little curved. Apical segment of the male with an arcuate excision, which is not
symmetrical, being most cut out on the right side, the apex between being acuminate
and finely carinate; the excision on each side is ciliate.
This latter character is most important, and in combination with the sulci will
determine the male sex of any of the species known to me.
1. Teretilanguria paname. (Tab. I. figg. 5, 5a, 3.)
Teretilanguria paname, Crotch, Cist. Ent. 1. p. 394.
“ 7. kirschit valde affinis, sed thorace antice paullo latiore, angulis anticis incrassatis; capite antice fortius
punctato lineisque frontalibus minus parallelis distincta videtur.”’
Hab. Panama?, Volcan de Chiriqui, Bugaba (Champion).
I do not find any example of this species in Crotch’s collection; but I have no doubt
that about a dozen specimens captured by Mr. Champion are referable to it, differing as
they do from T. kirschii by the strong punctuation of the head. Crotch, however, was
deceived about the difference in the form of the thorax. Though the sexes differ as
already mentioned, I can see absolutely no difference in this respect or in the structure
of the head between these and typical 7. kirschii, to which, therefore, it is very closely
allied indeed.
2. Teretilanguria metallica.
f&nea ; prothorace distincte acuminate punctato, depressiusculo; pedibus nonnunquam rufis. Long. 20-24
millm. ¢ 9.
Mas femoribus anticis parum incrassatis et curvatis, intus minute tuberculosis; segmento ventrali apicali
utrinque exciso, latere dextro profundius exciso, apice acuminato et carinato.
Hab. Nicaracua, Chontales (Belt); Costa Rica (Van Patten).
TERETILANGURIA. 9
Very close to T. panama, and possibly not distinct therefrom ; yet differing in being
entirely of a brassy colour, in the thorax of the male not perceptibly more convex than
that of the female, in the apical segment of the male more profoundly cut out on the
right side (although it is not cut symmetrically in any of the species), and also in its
rather narrower form.
The species of this genus are apparently very closely allied, and I believe that the
above given distinctions represent a separate species. I have as yet seen but three
specimens, two of which are from Costa Rica.
8. Teretilanguria nigro-nea.
Nigro-snea, nitida; capite prothoraceque crebre et distincte punctatis, illo trapezoideo; elytris obsolete sub-
striatis, punctis vix discretis, apicibus rotundatis et minute denticulatis, Long. 14 millim. ¢ 9.
Hab. Guatemata, Panajachel, Tamahu (Champion).
This insect is so similar in size and colour and general appearance to Trapezidera
cenea and to Dasydactylus chalceus, that, apart from generic characters, it is very difficult
to separate it. A comparison with these species will be better than any further
description: from the former, the more strongly punctate head and thorax, darker
colour, and the want of any basal marginal line to the thorax form sufficient superficial
characters of distinction ; from the latter, in addition to these differences, the structure
of the tarsi and the very obsolete puncturing of the elytra differentiate it; the elytral
teeth at the same time are stronger in 7. nigro-ewnea, and in the male the femora are
scarcely roughened, though longer and stouter in all the legs. Two specimens.
4. Teretilanguria versicolor. (Tab. I. figg. 6, 9; 6a, 3.)
Supra nigro-subviridis vel viridi-enea, infra flava, variegata, nitidissima; capite prothoraceque minute sparse
punctatis, illo ore, basi maculis nonnullis et infra, hoc lineis duabus vel maculis tantum in margine
antico femoribusque basi et infra, flavis; abdomine segmentis singulis nigro maculato. Long. 143-15
millim. ¢ 9. ;
Hab. Mexico, Toxpam (Sallé), Cordova (Hoge); GuaTeMALA, Purula, Sabo, San Juan
in Vera Paz, Cubilguitz (Champion).
Head with the eyes rather prominent; antenne black; face often much variegated
with yellow, the space round the base of the antenne and the orbit being sometimes so.
Thorax quadrate, rather convex, not differing much in the sexes; its underside, and two
spots from which lines proceed from the front margin, yellow, these lines sometimes
reaching the base and often only represented by the spots. Elytra smooth, green or
blackish. Abdomen yellow; the angles of the metasternum and each segment with a
blackish spot. The apex of the abdomen is excised unsymmetrically, but not so deeply
in the males as in the preceding species.

Two specimens, one from each of the above localities, and not altogether agreeing
with each other, present a very puzzling aspect. They appear to be very closely allied
to 7. nigro-cenea, but the eyes are less prominent and the cephalic structure is rather
that of Trapezidera. They probably belong to another genus, but the evidence is
insufficient for their proper assignment.

This species is only distinguished from LZ. sanguinicollis, Chevr., by having the
interstices of the punctured strie of the elytra with a very fine series of small punc-
tures, the punctures varying in strength. This is what I suppose to be implied by
Crotch’s remark “distinct by the punctate interstices ;” but as he does not include
L. sanguinicollis in the North-American species, nor say from what it is distinct, the
remark is ambiguous.

give a fresh description :—Head and thorax clear red, very finely and closely but obso-
letely punctured. The latter is oblong quadrate; the base rather narrower than the
front, truncate, scarcely sinuate, and finely margined; the basal striole represented by
two triangular fovee. Antenne, legs, pectus, and abdomen black. FElytra black; the
seven strive, and the sutural and submarginal strie also, with distinct, close, but not
very deep punctures; the interstices not quite smooth, the sculpture consisting of very
obsolete punctures and irregular elongate impressions. The prosternum is nearly
smooth, faintly transversely strigose in the middle, the sides with a few scattered
punctures.
b. Head black.
8. Languria capitata.
Nigra; prothorace subquadrato, postice vix angustato, modice convexo, rufo, margine antico tenuiter nigro,
crebre subtiliter punctato; elytris punctato-striatis, interstitiis crebre seriatim punctulatis. Long. 83-10
millim.
Hab. Muxico (coll. Gorham), Presidio (forrer).
Head black, sparsely punctured ; piceous or rufous towards the base and beneath.
Thorax rather shorter than in L. sanguinicollis; the sides very little rounded, except
at the front, narrowing very slightly to the base, the latter nearly straight ; the basal
striole faintly impressed and short. Elytra as in ZL. leta; appearing at first sight
multistriate, owing to the series of interstitial punctures being almost as distinct as the
strie. Abdomen nearly smooth, the apical segment punctured and finely alutaceous.
Legs black, the front coxe reddish.
This insect is allied to LZ. lwta; from L. collaris the form of the thorax at once
separates it.
Three specimens, also one in my own collection.

Hab. Mexico, San Andres Tuxtla (Sad/é).
Head black, minutely punctured. Antenne with a narrow, elongate, and laxly
articulated club of five joints; the apical four joints equal in breadth, the seventh joint
(the basal one of the club) triangular and narrower; from the base to the seventh joint
they are pitchy, the club itself being clear testaceous-red. Thorax rather longer than
wide, the sides rounded, the disc convex, the base margined, the hind angles rectangular ;
without striole. Elytra steel-blue at the base, black towards the apex, distinctly
punctate-striate ; with transverse depressions (possibly not normal but present in the
three specimens before me), and consequently somewhat uneven; interstices smooth ;
their apices strongly acuminate and polished, and, in one example, divaricate; the

sutural stria continued to the apex. Beneath the head and prothorax are coloured as
above; the mouth and trophi (except at the tips) are rufous; the prosternum is very
smooth, its process strongly arcuate, the apex being almost vertical and slightly excised,
and the sides thickened and raised; the breast and hind body are piceous, nearly black ;
and the apical segment is smooth, sparsely and not strongly punctate.
Three specimens: these present no sexual mark of distinction, unless the more
divaricate apices of the elytra be such. I have adopted the name under which they
were separated in Sallé’s collection.

The species thus briefly characterized by Crotch has the head, thorax, body, and legs
in part red; the apical segment of the abdomen is, however, black, and the apical half
of the femora, the tibize in part, and the tarsi, blackish. The antenne are black, but
sometimes the basal six joints are red, and frequently one or two are so. The elytra
are steel-blue, with very lightly impressed strie, the strize delicately but closely
punctured ; the interstices appear nearly smooth, though usually very finely wrinkled,
and occasionally (viz. in the example from San Juan) the multistriate appearance is
seen. Two Mexican specimens in Sallé’s collection have the elytra black with a faint
brassy tint, and an example from Panima and another from Colima have the punctures
of the strie deep and distinct, but I do not consider these differences of specific value.
The apical segment is depressed and pubescent; red at its base, but black in the
greater part.
It is impossible to identify this insect, which has the body red, with either L. simpli-
cicollis, Say, or with L. sanguinicollis, Chevr., as both those species are expressly
described as having the breast and abdomen black.
Crotch’s type and other specimens of L. cyanipennis were from Chevrolat’s collection ;
they are labelled as having been collected by Sallé. |

Prosterni processus intercoxalis ad apicem latior, truncatus, punctatus, parum declivus. Striola ocularis

Sexus differentia latet.
The species for which I propose this new generic name are somewhat similar to
those of the genus Langurites. The principal diagnostic character is the peculiar way
in which the elytra are acuminate at the apex, the apices being neither toothed nor
excised. The sutural margin is nearly straight, but the lateral margin is brought in to
meet it acutely from about one fifth of their length. The striation of the elytra is
distinct, and the punctures deep. The form of the thorax is very much as in Langurttes,
parallel and rather flat and acutely margined. The eyes are finely faceted, and there is
no ocular striola. The species, A. caudatus, which I regard as the type of the genus
Acropteroxys is coarsely punctured above and beneath ; and has the front part of the
prosternum very rugose, and the ruge interspersed with punctures. One or two other
species which I refer to it are allied to Languria gracilis, Newman, and are more
finely punctate than A. caudatus, but have the elytra similarly acuminate. L. gracilis
will probably be found to be congeneric, its elytra, however, are less acuminate ; the
general flat depressed form is the same, as is the widened apex and sculpture of the
prosternal process.
I include two species in this genus; one is apparently of wide distribution, ranging
from the Middle United States to Guatemala, the other from Mexico.

Hab. Mexico (ex coll. Sturm), Yolos (Sallé).
Head very coarsely punctured ; eyes rather prominent, moderately but not coarsely
faceted; without striole. Thorax very coarsely punctured; transversely rugose
beneath, the ruge with punctures irregularly interspersed, especially distinct on the
sides and on the prosternal process, the latter broad and wider at the apex; the sides
are very straight, and the length is one and a half times the breadth. Elytra with the
shoulders much wider than the thorax; the sides almost parallel for three fourths of
their length, acuminate beyond; punctate in series, the punctures coarse and often
confluent. Breast and abdomen punctured, the basal segment of the latter more
densely and coarsely than those succeeding. Legs and antennz blackish, the former
slightly pitchy at the base, the latter with the third joint longer than the fourth.
Only three specimens have come under my notice. Two of these are from Yolos;
the third is from Sturm’s collection, without special locality from Mexico.

The numerous synonyms quoted above show that this is a widely distributed and
also a variable insect. In the series in our collection all the varieties are included ;
but the Mexican specimens have the thorax usually black, or black with only the
anterior angles with a red spot; there are, however, a few specimens with the thorax
entirely red, with only a faint trace of a fuscous cloud on the part usually occupied by
the vitta. I cannot therefore doubt that these are all varieties of one species, as the
punctuation is identical. A single specimen only was met with by Mr. Champion in
Guatemala. The punctuation of the mesosternum is a good specific character, but
its red colour, mentioned by Crotch, does not hold good in dark specimens.
DASYDACTYLUS.
Pedes antici longi (maris femora et tibia intus asperi, tarsis setosis); tarsi latissimi. Antennarum clava
quinque-articulata plerumque brevis. Striola suborbicularis postice divergens, brevis. Prothorax
oblongo-quadratus ; maris convexus, antice latior. Prosternum leviter arcuatum, apice truncato vel exciso,
marginatum, interdum utrinque bifoveolatum. Elytrorum apicibus denticulis sex vel septem armatis,
rotundatis vel truncatis.
This genus has some features in common with the type of Goniolanguria, and indeed
one species, D. thoracicus, would come under Crotch’s definition of that genus, for a
minute carina for stridulating appears on the crown of the head; but in more essential
characters the species here brought together have a natural unity of structure which the
type of Goniolanguria has not in common with them. Indeed the species which forms
that type is, so far as I have seen, “sui generis.”
DASYDACTYLUS. 15
The species which I here unite have also a clear affinity with Trapezidera wnea; the
prosternum differing only in having its apex more depressed, and therefore not flat but
arcuate, and in some species the apex excised but not deeply.
The great difference consists in the sexual characters: the males having hairy and
strongly dilated tarsi and roughened femora and tibis to both the front and middle
pairs of legs; while the head here is uniform in both sexes, whereas in Gontolanguria
the left side is asymmetrically swollen. I have not seen specimens of any species
except from North and South America thus characterized; they seem to be closely
allied, and locally restricted, and must be numerous.

1. Dasydactylus buprestoides. (Tab. I. fig. 7, ¢.)
Aneus ; antennis breviusculis, nigris ; capite fortius, prothorace subtilius, punctatis, crebre alutaceis ; elytris
subtiliter punctatis, vix striatis, apice oblique truncatis et denticulatis; abdomine piceo, lateribus

Mas prothorace convexiore, postice latiore ; femoribus tibiisque anticis et intermediis intus asperatis.
Hab. Mexico, Cordova (Hége).
The head and thorax in this species are rather thickly and strongly punctured, and
their entire surface is finely alutaceous (a character by which the female of this insect
may be known from a Trapezidera also occurring at Cordova); the reflexed edge of the
latter is obliquely and finely wrinkled. The prosternum is rugulose; the process
nearly smooth, with a double fossa near its apex, its apex truncate. The thorax of
the male is very convex in front, and wider than the elytra; that of the female trape-
ziform, and hardly so wide at its base as the elytra; the base is very finely margined,
with the basal striola only just indicated by a punctiform impression. The elytra
taper very gradually but decidedly; their apex is obliquely truncate, though somewhat
rounded in the females, and denticulate ; their punctuation fine and close and confused,
the striz being hardly defined; here and there the punctures form series. The under-
side is smooth (excepting the mesosternum); the apical segment of the male faintly
carinate, and obsoletely punctate and ciliate, that of the female very similar. The
general colour is brassy, the antenne being bluish-black.
But few specimens of this species were collected by Herr Hoge. The females so
strongly resemble that sex of a form of Trapezidera enea, that T. buprestoides may
easily have been overlooked as distinct from that insect. The males have much longer
legs, of which the two front pairs have strongly roughened femora and tibie ; even the
femora of the hind pair in this species are a little roughened.

Hab. Panama, Bugaba (Champion).
The species of this section have a greater resemblance to the genus Goniolanguria
than those which follow; I do not think it necessary, however, at present to give them
generic rank, but if Iam not mistaken the following points of difference will unite a
group including some undescribed species from South America:—the legs very thin
and long; the head very depressed and very smooth, the eyes prominent; and the
apical segment of the abdomen almost keeled, the central line being a definite ridge,
but not raised, and also subacuminate. D. subulatus is one of the brightest of the —
Central-American “ Languriides,” the elytra being usually of a bright metallic green
inclining to rufous at the base, while the head and thorax are piceous with a green
reflection. The mouth is rufous; the antenne of moderate length, with an elongate
club of five joints. The thorax is.half as long again as wide; in the female the sides
are nearly parallel at the base, and from the middle narrowed and rounded a little to
the front angles; the base has a transverse depression terminated on each side by the
punctiform but obsolete striole, and the impressions on this are ill-defined, and the
central lobe is short. Scutellum transverse. The elytra at the base are as wide as the
thorax. The colour beneath is more or less evenly rufous; and the legs are clouded
towards the knees, and on the tibia. The roughening of the front femora is not very
distinct, and as it is present in a small degree in the females does not form a good
sexual diagnostic. In the longer hairs of the front tarsi there is as much difference as
usual.
A good series of this insect was secured by Mr. Champion.
3. Dasydactylus glabricollis.
Biceus, infra dilutius, supra saturatius et eneo-micans, nitidissimus; capite prothoraceque fere glabris; elytris

Smaller than D. subulatus, and with a shorter and consequently more quadrate
thorax. The elytra are wider at their base than any part of the thorax. ‘The femora
in the male appear to be quite smooth, and the tibiz seem only to differ from those of
the female by their greater length. Although there are but a few specimens from each
of the localities, and these differ a little in size and colour, I believe they represent but
one widely distributed species.

Hab. Mexico, Toxpam, Cordova (Sallé).
The head and thorax are very minutely and obsoletely punctured (so as to appear
almost glabrous under an ordinary lens of an inch or longer focus), and bluish in tint.
The thorax is oblong, narrow in front; the sides in the male are slightly rounded, in the
female nearly straight ; the base is wider than the front in both sexes, and has in the
middle a faint transverse depression along which are a few larger punctures, the margin
very finely reflexed, the striolz indicated by punctiform impressions. The elytra are
decidedly wider at the shoulders than the thorax, blackish-bronze in colour, and thickly
and confusedly punctured, the punctured strize being distinct towards the base, but
confused with the interstitial punctuation towards the apex.
The form of the prosternum, or rather of its intercoxal process, is very important in
distinguishing the species of this genus: in this insect it is slightly arcuate, and the
apex (this part being less depressed than in some allied species) is truncate, or at all
events very slightly emarginate ; it is also smooth. The antenne are moderately long ;
the third, fourth, and fifth joints elongate, the sixth shorter than those preceding, but
still longer than the seventh, the latter triangular in shape; these joints are all more
or less shining, bluish-black, while the club is black and opaque, the latter being rather
laxly articulated but still wide. The tarsi are clothed beneath with soft golden hair,
which is longer in the male in the front pair.
5. Dasydactylus puncticeps.
Nigro-sneus, nitidus, corpore subtus pedibusque rufo-piceis, antennis tarsisque nigris; capite fortiter parcius,

Head thickly and strongly punctulate, the crown less thickly so; orbital striole well
pronounced, scarcely diverging from the eye behind. Thorax trapezoidal, but con-
siderably narrower in front than at the base; densely but finely punctured (not
~ alutaceous as in D. buprestoides) ; base rather widely and flatly depressed as far as the
punctiform impression. Elytra in large specimens narrowed behind (as in D. bupres-
toides), in smaller ones less distinctly so; densely punctate; the punctures in one small
male, at least at the base, indicate striae, but in larger specimens they are very evenly
dispersed, in the single female example they form strie; the apices are not truncate,

but rounded and with about seven denticules on each. The legs are pitchy-red, the knees
and the tips of the tibie and tarsi blackish, and very long in both sexes. The antenne
are black, the apical five joints opaque, these latter forming an elongate and not very
wide club.
This insect is labelled “ Languria enea, Chevr. (ahena, Sturm),” in Sallé’s collection,
but is generically distinct from the types of those species. From D. buprestoides it is
to be distinguished by the darker brassy-black colour, the rounded tips of the elytra,
and the punctuation of the head and thorax. ‘The punctuation of the elytra in this
and other species is a variable and uncertain character.

The diagnosis is taken from the type in the Cambridge Museum. The essential
character by which this species differs from that here described under the name of
D. puncticeps is the nearly smooth head. Crotch did not notice the roughening of the
femora, not having seen females ; the single specimen in his collection is a male of the
larger size, and with it I associate three other examples.
7. Dasydactylus nitidus.
Nigro-subzneus, nitidus, pedibus nigro-piceis, antennis tarsisque nigris; capite crebre, prothorace obsoletius,

This species is very close to D. puncticeps, and separated from it chiefly on the
following grounds :—the antenne are not so long, and have the third to the sixth joints
very evidently shorter; the legs, especially the middle and hind pairs, also shorter.
D. nitidus is also a rather smaller insect; and has the thorax less widened at the base,
and the femora less distinctly rough in the males.

black, the club (as in other species where no difference is specially mentioned) five-
jointed and duller than the basal joints, the seventh or first club-joint being much
narrower than those following and less pubescent. Head rather sparingly, the thorax
thickly and distinctly, punctured ; scutellum transverse. Elytra rather more distinctly
punctate-striate than in D. nitidus; the sutural stria impressed more deeply at the
apex, but the apex itself is not so acuminate as in D. nitidus. Prosternum rather
broad, arcuate, its apex truncate but depressed.

This species is distinguished among its very near allies by its rather short and convex
thorax being as wide as the base of the elytra in the male; by the elytra being rather
distinctly punctate-striate, with the interstices sparingly but serially punctured, and
their apices obliquely truncate; and by the prosternal process being arcuate and excised
at the apex (but not deeply), the margin being reflexed at the angles. In one example
there is what appears to be a stridulating file on the crown of the head, and this might
cause it to be referred to Crotch’s genus Goniolanguria. This is not, however, to be
seen in other males; and in other characters, as the structure of the legs and tarsi, the
absence of the asymmetrical gena, &c., it diverges from the type of that genus, which
has been but imperfectly characterized by Crotch.
This insect perhaps comes nearest to D. punctisternum, it is also closely allied to
D. hondoensis, though larger and blacker. :

A species easily to be separated from D. levicollis, which it rather nearly resembles
in sculpture, by its somewhat stouter and shorter form, blue-black colour, and the
coarse sculpture of the prosternum. The body beneath is black ; and the very obsolete
denticulation of the tips of the elytra is noticeable, showing as it does how this
character fails to be of much generic importance.
Three specimens in Sallé’s collection.

The head and thorax of this species are rather thickly and minutely punctured, the
latter less thickly than the former; and the elytra have series of very fine punctures and
the interstices nearly smooth. The thorax is strongly depressed before the base, and
has a very faint indication of a central channel in the depression; a minute impression
represents the basal strige, the transverse impression between being fairly well marked
and punctured. The amount of dilatation and the hairy clothing of the front tarsi in
the male is well marked in all the species of this section, the three dilated joints having
the soles clothed with whitish silky hair and the sides with long black ragged hair.

This species agrees very closely with D. zwnilensis in several of its characters ; it is,
however, narrower, the base of the elytra especially, which hence appear very cylin-
drical and less narrowed to the apex, and the thorax of the male is also narrower; the
punctuation of the head and thorax is less thick; the elytral series of punctures
are distinct at the base, but towards the apex the interstitial punctures are more
numerous and here become confused with the strie. The colour above and beneath is
blacker than in D. zunilensis. The typical specimens are a male and a female from
Chontales.

Hab. Mexico, Toxpam, San Andres Tuxtla (Sallé), Cordova (Hége); Britisu
Honpvuras, Belize, R. Hondo (Blancaneauz).
This species bears a very close resemblance to D. thoracicus, but the elytra are not
so pointed towards their apex, and are not truncate; the prosternum is decidedly and
strongly bimucronate at the apex of the process, and also differs in other respects. It
is really more nearly allied to D. hondoensis and D. picipes, three species extremely
difficult to discriminate; the head and thorax in D. sudbtilior are, however, so very
finely punctured that they appear glabrous under an ordinary pocket-lens of an inch
and a half focus. D. sudtilior is also larger, blacker, and has a longer thorax than
D. hondoensis; and the thorax of the male narrows in front, where it is narrower than
at the base.
In the specimen from Cordova the interstices of the elytra are punctulate; but in |
others, as the one from Tuxtla (¢), they are nearly smooth, though finely rugulose ;
in the British Honduras specimens all the punctures are more obsolete, so that I do not
think any good characters can be drawn from the elytral punctuation. I think, however,
that the very fine punctuation of the head and thorax is constant.
14. Dasydactylus cribratus.

Hab. Mexico, Teapa in Tabasco, Tapachula in Chiapas (Hége).
A species allied to D. hondoensis, but easily distinguished by the long thorax and
punctulate prosternum. The thorax is longer than in any species yet described, except
D. longicollis. The punctures on the prosternum are large and scattered; the process
is smooth but longitudinally furrowed and uneven. The legs of the male are long and
as in D. hondoensis ; but the front tarsi are much less widely hairy, and are narrower.
The thorax is less shining than in its near allies, owing to the punctures, though
distinct, being thick. Four specimens were captured by Herr Hoge during his second
expedition to Mexico.

Very close to D. thoracicus; in the male the thorax is widest in front a very little
below the angles (in D. thoracicus the widest part is below the middle); the legs are
not nearly so long, and the hairs on the tarsi in the male are black; the antenne are
shorter, especially the third to the fifth joints; the elytra are less distinctly punctured,
and have their apices acuminate and rounded. The legs and underside vary in the
degree of depth of pitchy-red colour.
I have described this species from specimens from British Honduras, where it appears
to be very abundant. The specimens from Mexico pertain, I believe, to the same
species, and are very difficult to separate from D. teredilis, with which it was found by
Herr Hoge.

Smaller than D. nitidus, and, in addition to the prosternum being channelled and
excised at the apex, differing from it as follows:—The thorax is shorter, and in the
male widened in the middle rather than near the base (which is accordingly more
constricted), and covered with more distinct but more scattered punctures; the inter-
stices of the elytra are less thickly and less serially punctured, the strize themselves
being more strongly punctate. Many specimens were captured at Cerro Zunil by
Mr. Champion, and what appears to be the same species occurred in some numbers at
Duenas.

One of the smaller species evidently composing a series very nearly allied and hard
to separate. The males of D. teredilis have the thorax very wide and convex, the
middle of the thorax being the widest part of the insect; the antenne of moderate
length, ¢.¢. about as long as the head and thorax together, the third to the seventh
joints subequal and longer than wide. The front legs are long, but the middle pair
is shorter than in some species of the genus; and their femora appear to be smooth
in the males.

Very nearly resembling Languria cyanipennis, Crotch; similarly coloured, but more
cylindrical, and with the thorax more coarctate behind. The head and thorax are very
finely, rather closely, punctate, and often inclining to bluish; the elytra are more distinctly
punctate than in LZ. cyanipennis, and have the interstices narrower and here and there
irregularly punctured. The males will be easily recognized by the characters given.
The apices of the elytra are very faintly denticulate (so as hardly to be thus termed) ;
yet this character, which may be seen in some specimens of both D. cyanopterus and
D. sellatus, is important as confirming their relationship with the other species of this
genus. Four specimens.

Bright ferruginous-red ; the tarsi black, the claw-joint and claw reddish ; the basal
third and tip of the elytra steel-blue; the tip of the abdomen black; the apical and
greater part of the preceding ventral segments also black. In several examples the
femora, tibiee, tarsi, and antenne are indistinctly clouded with bluish-fuscous. The
elytra are subulate; their apices almost pointed and faintly serrate, but not denticulate ;
distinctly punctate, the strize so close as almost to be confused. The prosternal process
is margined and greatly cut out at the tip. The male characters are similar to those
of other species of Dasydactylus; but the hairs of the tarsi in both this and D. cyano-
pterus, to which it is nearly allied, are fine and silky; the femora and tibize of the
front and middle legs are distinctly roughened. |
One specimen, apparently not otherwise different, but with the head black, was
captured by Herr Hoge at Teapa.

The Langurites ventralis of Crotch’s ‘Revision’ is not this species, but merely a
unicolorous specimen of L. lineata. Chevrolat’s type is, however, contained in the
Cambridge collection, and agrees with several specimens similarly named in Sallé’s
collection. It is a small species of a bluish-green iridescent hue, often inclining to
pitchy. The prosternum is distinctly roughened on the sides; with small tubercles
similar to those on the femora of the males; its apex is excised, but not deeply, and
the angles are prominent, and in D. ventralis (and probably in other species) this
appears to be especially the case in well-developed males. ‘The elytra at the shoulders
are distinctly wider than the base of the thorax. |

Hab. Panama, Volcan de Chiriqui (Champion).
Antenne fuscous; the club rather elongate, though the separate joints are quite
twice as wide as long (yet they are not so wide as in many species of this genus); the
third to the sixth joints short, not much wider than long. The supraorbital striola is
very short. The thorax is oblong, narrowed in front, widest at the base, the basal
margin depressed in the middle and crenulate, the basal strige hardly distinct. ‘The
elytra are a little wider than the thorax at their base, tapering very evenly to their
extremity. D. concinnus has very much the appearance of a species of Trapezidera, as
represented by 7. wnea; and as the three specimens (which are all I have found among
a large number of ‘ Languriides’ from the Volcan de Chiriqui) appear to be all females
it is of course not unlikely that the species will have to be removed from this genus.
It is apparently not a Teretilanguria; and the prosternum being excised it is better
placed here than in any genus at present characterized. D. concinnus is an extremely
neat and narrow insect,
NOMOTUS.
Pedes antici haud longi; femora valida, parum clavata; tarsi modice lati, subtus albo-hirtuli, haud longe

The species forming this genus are practically Languri@ which have the apex of the |
elytra minutely denticulate. But as the genus Languria has not yet been accurately
defined, it will be better here to compare the typical species, Nomotus plutonus, with
NOMOTUS. 25
those of the other genera to which it bears any resemblance. From any species of
Dasydactylus, the absence of long hairs from the front tarsi, the thickened femora,
shorter legs, and more cylindrical form will sufficiently distinguish it; the claw-joint of
the tarsi is also shorter. The antenne are rather longer than is the case with middle-
sized species of Dasydactylus; the club, though large and rather heavy, is not distinctly
5-jointed (the seventh joint is so little produced on its inner side as scarcely to
appear widened, and does not really form part of the club); and there is no trace of
any roughening of the femora. From Languria proper, such as L. leta, the denticu-
lation of the apex of the elytra is perhaps sufficient.

Hab. Panama, Bugaba (Champion).
The colour of this species is wholly black above and beneath. The head and thorax
are very smooth and shining; the latter rather convex, its sides rounded, widest about
the middle, the base with a strong transverse depression, the basal striole short but
distinct, the space between the latter almost smooth and with only a very few obsolete
punctures. Scutellum orbicular, a little pointed behind. Elytra punctate-striate, the
interstices nearly smooth; the sutural stria distinctly impressed as it approaches the
apex, but the depression not so deep as in the following species. ‘The femora in what
I take to be the males of this species are very robust and distinctly clavate, especially
the front pair; the tarsi also appear to be wider than those of the female, but the
difference is not so great as to render it absolutely certain that I can separate the sexes.
Many specimens of this insect were secured by Mr. Champion at Bugaba.

Very close to WV. plutonus, but rather larger, and with a brassy reflection which is
not present in that species. The whole insect is proportionally rather longer, the
sutural stria is more distinctly impressed, and the depression of the suture at the apex
is deeper. Other points of difference are the punctate interstices; the finer punctures
of the strie; and the thicker and more distinct punctuation of the thorax, especially at
the base, where the basal depression is usually covered with deep and coarse punctures
and sometimes even foveolate.

black, and may prove to belong to a distinct species. |

In addition to the characters given 1 I add the following :—Tarsi clothed with short
thick hairs on the soles; antenne set in deeply margined sockets, there being a space
between the eye and socket; the epistoma ill-defined by a depression; the ocular
canthus bordered above by a straight, smooth, ridge, the striola short and not deep;
scutellum transverse, punctured (0. concolor) or only impressed (0. batesi) ; prosternum
broad, margined, truncate, but little excised, and much depressed at its apex; meso-
sternum coarsely punctured ; ventral apical plate of the abdomen rather broadly rounded,
faintly emarginate, not distinctly punctate, nor very pubescent (0. batesi).
The species we record from Mexico is much smaller than, but otherwise very similar in
build to, O. concolor; the two described by Crotch (0. batesi and O. concolor) are both
from Tropical South America. .

wide; pitchy, the disc darker and faintly bluish; the base margined, and with coarser
punctures; and with very slight traces of a basal striga. Elytra with the tips round, a
little acuminate, and obsoletely denticulate. Femora rather stout and a little sinuate.
Underside of the body, the coxe, and trochanters pitchy-red. Five specimens. .

Differs from O. elongata by the rather more prominent eyes, and the nearly smooth
head and thorax, the only punctures on the head being a few on the depression marking
the epistoma and a very few minute ones behind the eyes. The thorax is quite free
from punctures, but has a transverse basal impression terminated by a punctiform
indication of the striola. The elytra are faintly brassy, especially at the shoulders; the
sutural stria is rather well marked ; their apex accords more with the type of the genus
than does that of O. elongata. The apex of the ventral segment is broad and emargi-
nate, though very indistinctly so. ; Costa Rica®, Cache (Rogers); Panama, Bugaba, Volcan de

The older authors considered this insect to be a mere variety of C. unicolor, a species
which occurs further south; but it is probable that they confounded with it others of
similar appearance. The references to Latreille and to Duponchel are given, as those
authors probably refer to this species in the text, though their figures do not apply to
it—that in Humboldt’s work probably represents a Coccimorphus, but one more like
C. emys, and the Mexican locality, “ Nouvelle Espagne, Jorullo ” °, pointing also probably
to that species. Crotch gives “Guatemala ;” there is, however, no specimen from that
country in his collection.

This species is more elongate and less convex than any other of the genus known to
me, and hence has more the appearance of a Coccimorphus. It is elongate-ovate in
shape, acuminate before and behind, moderately convex, of a uniform dull brick-red
colour, smooth, and a little shining beneath, and without punctuation, excepting only
that the epistome has a few very small indistinct points. The antenne are black, with
two joints at the base red, their third joint elongate; the club is composed of four
joints, and is rather narrow, the eighth, or first club-joint, not so long as the ninth, and
this one longer than the two succeeding it. The margin of the antennal socket bears
a single puncture (present also in Coccimorphus dichrous and some other 4igithi); the
tips of the mandibles are black. The scutellum, tips of the femora, tibie, and tarsi
are black. There are no metasternal nor abdominal lines. Prosternum even, rather
raised in the middle, but not compressed, nor acuminate in front. The punctiform
setigerous dot on the middle of the first ventral segment in the male is a character
unusual in this genus, but occurs in Hrotylus, and rarely in other genera (as we have
seen in Mycotretus); and what is more noteworthy still is that there is a similar but
less conspicuous dot on the middle of the prosternal process in this species. We have
received a large series of this insect. It was found abundantly by Mr. Champion at
San Gerénimo. There is one specimen unnamed in the Cambridge collection.
I have retained the name with which it is labelled in Sallé’s collection.

I cannot agree with Crotch in thinking that 4. rujfipennis, Chevr., and 4. meri-
dionalis, Crotch, can possibly be forms of 4. cardinalis: they are accordingly here
kept distinct; a third species, which has been confounded with 4. cardinalis, is
described below, as there are abundant distinctions, and they occur in different
districts. . |
Mr. Champion’s capture of 4. cardinalis in Guatemala is an interesting discovery.
There are no specimens other than Mexican in Crotch’s collection or my own. The
small variety found by Hoge at Jalapa is peculiar on account of its uniformly small
size: there were about a dozen, specimens all alike. Mere colour variety, such as the
var. A, noticed by Lacordaire, is of no importance, and occurs in all the red and dark
yellow species of Erotylide. | |
Of this insect we have a large series of specimens.
The prosternum is somewhat compressed in the middle, but is not acuminate in
front; the antennal orbit has its margin flattened above, with a small oblong puncture
and striola joining the ocular canthus.

Of the same form as #. cardinalis, but more convex; the elytra more produced and
more depressed towards their apex, and hence more gibbous when viewed laterally.
Although this species so far resembles 4. cardinalis as easily to be confused with it, it
may readily be distinguished by the total absence of any black discoidal mark on the
thorax. It also differs structurally, the prosternum being produced into an acuminate
point in the middle of its front margin. In colour &. politus is usually of a more
yellow- than blood-red; and the elytra, perhaps from their greater convexity, have a
more polished look than those of either . cardinalis or 4. meridionalis.

Very short and convex; the thorax distinctly shorter and more transverse than in
44. cardinalis or 42. politus, the sides very strongly narrowed and a little rounded.
Deep brick-red above, the antenne, legs, scutellum, and underside black ; specimens,
however, occur with the prosternum pitchy or even reddish. The upper surface is
entirely impunctate (with the exception of the epistome, which is alutaceous and
obsoletely punctate) and the elytra non-striate. There is the puncture and striola above
the antennal socket. The prosternum is not acuminate in the middle of the front, nor
much compressed. The metasternal line is distinct, carinate, running nearly across the
episterna, then deflexed and passing to the corner of the metasternum and merging in
its margin.
There is some confusion about this species—Crotch’s type specimen, bearing the
name £4. meridionalis in his own handwriting, is from Costa Rica, and has the
prosternum quite black. Again, although Crotch says the Chontales specimens all
pertain to @. meridionalis there is no specimen in his collection from that place, and
I have reason to think they were at least partly 4. politus, Gorh., which he did not
distinguish. |
This insect is perfectly distinct from 4. cardinalis, 4A. rufipennis, &c. About a
dozen examples are before me.

Ovatus, subopacus, dilute brunneus; antennarum articulis sex ultimis nigris, elytris gemellato-punctato-

Hab. Mexico, Chilpancingo in Guerrero (Hd6ge).
Rather evenly oblong-ovate, the elytra a little contracted at the base. Head and
thorax smooth; the latter transverse, narrower in front, the sides a little rounded, the
base evenly bisinuate and not much angulated (less so than usual in Agithus). Elytra
dull, but very even; only the two inner pairs of strie are visible, and they are very
faint and almost obliterated, except in the middle. Prosternum not compressed nor
punctured. The colour is uniformly pale brown, or ochraceous inclining to brick-red,
with the sole exception of the six terminal joints of the antenne, which are black.
This insect is not very closely allied to any other described species, but must be placed
near 4. lebasi. I have only seen the four specimens captured by Herr Hoge.

This is a rather variable species and apparently liable to discoloration, but the
amount of variation is not great. Sometimes the tibie are wholly black; in some
examples the thorax has only the base on each side of the middle narrowly black, while
others have three distinct triangular dots (the middle one the most produced) on the
base. In the single specimen in Sallé’s collection (which is the only one I have seen
not discoloured) the general colour is pale ochraceous-yellow; six joints at the base of
the antenne are yellow, but in the Chontales examples, which seem to be otherwise
inseparable, only two are yellow; and the episterna are pitchy-black. The front margin
of the thorax is often narrowly black in the middle. The gemellate series of punctures
on the elytra are distinct, but not large, vanishing one third before the apex, and the
external pair are almost obsolete. The oblong-oval, but acuminate, form distinguishes
this species from any of its section at present described. It is very like Strongylosomus
peruvianus, Crotch, in general appearance, but the longer antenne prevent its being
placed nearer to that species.
A considerable number of specimens were obtained by Mr. Champion. I have only
seen two from Nicaragua.
15. Aigithus strigicollis.
Late ovatus, ferrugineus; prothoracis striga longitudinali, antennis pedibusque nigris, scutello fusco, elytris -
nitidis, gemellato-striatis. Long. 7-9 millim.
Hab. Panama, David, Bugaba (Champion).
Closely allied to @. lineola, Lac.; but rather more acuminate before and behind, more
shining, and of a clearer rusty-red colour. The second joint of the antenne alone is
testaceous, the basal joint and the long third joint being more or less infuscate or
almost black. The epistoma is minutely but obsoletely punctured. The elytra are
very finely but distinctly gemellate-striate, with small close punctures in the striae, as
in 4. lineola. The legs are black, but have the coxe and trochanters of the colour of
the body. Body beneath smooth; the metasternal line distinct, reaching to the
episterna. Five examples, varying in size but not much in colour. The scutellum is
scarcely darker than the elytra in two of them.
16. Aigithus dubius.
Breviter ovatus, convexus, nitidus, brunneo-testaceus; antennis (articulis duobus primis exceptis), scutello,
tibiis tarsisque nigris ; capite prothoraceque glabris, elytris levibus, obsolete punctulato-striatis, punctulis
ante apicem desinentibus. Long. 7 millim.
Hab. Panama, Bugaba, Caldera (Champion).
Nearly of the same form as &. lineola; but more polished and shining than either
that species or 4. strigicollis, and the elytral striz are not gemellate. The third joint
of the antenne is partly yellow. The thorax is spotless, very shining, and glazed; its
sides are more rounded than in 4. strigicollis, and very much narrowed from the base
EGITHUS. | 91
to the anterior angles; and the base is not so much angulated, but almost straight
(though slightly bisinuate) and with a broad and indistinct median lobe. ‘The elytra
are very smooth and glabrous and have numerous rows of fuscous dots; the punctures
are larger and more distant than in J. strigicollis, and eight rows are visible though
they terminate at one third from the apex. ‘The underside and femora are rather paler
ferruginous-red than the upperside usually is, glabrous, and shining. The prosternum
is not compressed but convex; the metasternal lines are distinct, and produced back-
wards till they unite with the marginal impressed stria.
This and some other allied species might from the form of the thorax be placed with
equal propriety in Brachysphenus, the V-shaped form having quite merged here into
the ordinary form. 4. dubius is, however, clearly allied to Ayithi of the 4. mono-
chrous and 4. lineola group; and there is really no other distinction than that of
general form between the two genera.
Five specimens from Bugaba and one from Caldera.
17. Adgithus stillatus.
Breviter ovatus, convexus, flavo-ferrugineus, nitidus; capitis puncto, antennarum clava, prothoracis lineis

elytris punctulis impressis, punctis nigris cingentibus, interdum obliteratis. Long. 6-73 millim.
Hab. Mexico (Sallé); British Honpuras, Belize (Blancaneauz).
This is a very curious species, not allied to any other known to me; but from the
numerous black dots on the elytra recalling 4. burmeistert. The head and thorax are
smooth and shining—of a rich fulvous-red in the Mexican example, yellowish in the
Belize specimens. ‘The antenne have a four-jointed club; these joints and one or two
preceding them are black, the basal joints being testaceous. The elytra are brownish-
yellow (as in &. punctatissimus and 4. burmeisteri); the suture and lateral margins in
the Mexican example being of the rich red colour of the thorax, but in the Belize
specimens very narrowly black. ‘The legs and underside are fulvous, the tibie exter-
nally and the tarsi infuscate, the episterna pitchy. The metasternal lines are visible.
Two specimens from British Honduras and one from Mexico are all I have seen of
this species.

one median (like three oblong spots united), one subapical (heart-shaped), and one
in the middle of the suture, common to both elytra, oblong. Legs testaceous-red, the
extreme tips of the thighs and the tarsi dark pitchy-red, the tibie almost black.

The synonymy quoted above will show that this is a very extensive genus whose
limits it is difficult to define. In treating of a local fauna it would be undesirable to
revive any of the above names. Lacordaire only notices them as subgenera. We
quote them as they have been so generally used in collections. Brachysphenus contains
about one hundred and eighty described species, but many more exist in collections.
They are all American, and are confined to the tropics. The species are generally of
moderate size, and very varied in colour and pattern.

The specimens which Mr. Champion collected of this beautiful species are con-
siderably larger than the two from Panama in Crotch’s collection, being a little over
eight (instead of from six to seven) millimetres in length. It is distinguished from the
species which follows, and with which it might easily be confused, by the more oblong
form, by the different denticulations of the yellow fasciz (which a reference to the
BRACHYSPHENUS. 93
figures will explain better than any description), and also by the yellow margin of the
thorax. The single example from David (fig. 8) is a distinct variety, in which the
pitchy-black disc of the thorax is divided into four spots.
2. Brachysphenus pulcher. (Tab. V. fig. 9.)
Ovalis, postice subacuminatus, dilute piceus, supra saturatius piceus vel nigro-piceus, nitidus; elytris striis

ad humerum reflexa, denticulis duobus interioribus, tribus exterioribus; posteriore arcuata, denticulis
tribus exterioribus, duobus interioribus, et ad suturam versus apicem reflexa), late flavis. Long. 8-8}
millim.
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).
More convex and more widely oval than B. delineatus; the head and thorax pitchy-
black, the front of the former and the front angles of the latter paler, but never with
any defined yellow margin. The much indented yellow fasciz are somewhat similar to
those of B. delineatus; they do not, however, as in that species, form two round black
spots at the base of the elytra, but one bifurcate spot. The posterior fascia is reflexed
at the suture towards the apex of the elytra, whereas in B. delineatus it is retiexed
towards their base. The underside in both species is plain pale pitchy-red. The
prosternum is rather more acutely compressed in front in B. delineatus. The legs in
both are pale pitchy-red.
Mr. Champion captured many examples of this very beautiful insect.
3. Brachysphenus catillifer. (Tab. V. figg. 10; 11, var.)
Brachysphenus zonula, Crotch, Cist. Ent. p. 147° (pars).
Oblongo-ovatus, parum convexus, flavo-ferrugineus, verticis puncto, prothoracis disco elytrisque piceis, his
fascia basali cum altera pone medium obliqua per vittam lateralem conjuncta; antennis piceis, articulis
duobus basalibus rufis. Long. 74-9 millim.
Hab. Nicaragua, Santo Domingo in Chontales (Janson1, Belt); Costa Rica, Cache
(Rogers).
I have carefully compared this insect with Crotch’s type-specimens of B. zonula in
his collection, and come to the conclusion that it is a distinct species from the Ecuador
insect. It differs as follows:—It is shorter and more robust; the ring-like band in
B. catillifer covers the shoulder, instead of leaving it of the pitchy-black ground-
colour; and the posterior part of the hind fascia is more produced towards the apex of
the elytra.
Janson’s specimens have the basal fascia denticulate, but Belt’s have the band nearly
or quite simple, as is also the case in one from Cache.

duabus flavis, una basali, altera postmediana obliqua, latiore, subdenticulatis. Long. 7 millim.
Hab. Panama, Volcan de Chiriqui (bbe).—Perrv (coll. Gorham).
This insect though evidently allied to B. fasciellus and its allies is less convex; the
thorax especially is flatter, and it is entirely black. The body moreover is black,
instead of being, as usual in species of that section, yellow or pitchy. The basal yellow
fascia of the elytra leaves the shoulder and a double spot near the scutellum black ;
the black portion between this and the postmedian fascia is much narrowed towards
the margin; the epipleure are yellow; and the seven series of rather large punctures
are quite distinct. Only one example of this species has been received from Chiriqui,
and its antenne are almost entirely gone. I possess, however, two specimens of the
same species collected in Peru by the late Mr. Buckley, which only differ in being
slightly larger, and in one of them having a small pitchy spot on the thorax near the
front angles, while in the other the head is entirely black.
5. Brachysphenus nuculus.
Ovatus, convexus, nitidissimus, niger, abdomine elytrisque fulvis, ore rufo. Long. 8 millim.
Hab. Mexico, Toxpam (Sal/é).
The head and thorax are black and very shining; the former is broadly impressed in
front, with the labrum and palpi rufous; the antenne are black and as long as the
head and thorax; the front margin of the latter is semicircularly excavate; scutellum
black, partly covered by the median lobe of the thorax; elytra quite smooth and
without striee, although darker lines faintly indicate their position ; body and legs quite
black and smooth; the prosternum compressed and elevated in front; abdomen bright
red, of the same colour as the elytra. This species is coloured exactly like B. fulvi-
ventris, but is smaller and has precisely the form of a Megaprotus.

not very strong. Elytra broad, very even, with fine punctured striz, the interstices
quite flat and even, the series evanescent towards the apex. Underside quite smooth
and even. The prosternum has a broad intercoxal process, with a minute impressed
puncture on each side, the front not much compressed and terminating in a point which
is but little produced or elevated. The central part of the mesosternum is transverse ;
the metasternal lines are very distinct, terminating before reaching the episterna, the
latter with the epimera broad and smooth. The abdomen is not quite so even as the
rest of the underside; the segments are vaguely impressed on each side, and these
impressions are sometimes infuscate. The legs are black, including the trochanters,
but the coxe are entirely of the waxy-yellow colour of the body, and the claws are red.
Eight specimens of this very neat though plainly-coloured species were obtained, two
of them at elevations between 4000 and 6000 feet, the others at lower altitudes on the
Volcan de Chiriqui.
7. Brachysphenus exiguenotatus.
Ovatus, convexus, brunneo-castaneus, antennis (articulis duobus basalibus exceptis) nigris; elytris postice

Hab. Nicaraaua (Sallé); Panama, Volcan de Chiriqui (Champion).
Of the form and size of B. spadiceus, or nearly so; very polished and shining; the
thorax very short and transverse, its disc convex and very smooth, its sides narrowing
from the base and very faintly rounded, the base gently bisinuate and with a few
obsolete punctures along the margin, the median lobe feeble. Scutellum red. Elytra
very convex, ovate-cordate, slightly gibbous; each with seven rows of rather distinct
punctures, vanishing towards the apex, and each with a black dot, made up of two or
three black punctures, at the base of the third and fourth striz, and a similar but often
double dot on the sixth and seventh strize near the middle. Prosternum strongly
compressed and pointed in front. Margins of the epipleure blackish; the base of the
tibiz infuscate.
Two specimens from Nicaragua and one from the Volcan de Chiriqui.
8. Brachysphenus brevicollis.

Head and thorax glabrous, shining, pale rusty-yellow; the latter very short, and with
the disc convex, the sides strongly contracted to the front angles and very evidently
rounded, the front angles acute and prominent, the base bisinuate and with a well-
defined median lobe. EHlytra almost smooth, but with striz formed of fuscous punc-
tures visible beneath the surface and only minutely impressed above. Scutellum black.
96 EROTYLIDZ.
The antenne are as long as or a little longer than the head and thorax; the two basal
joints yellow, the third pitchy or varied with yellow and black, the fourth and fifth
elongate and fusiform, the sixth and seventh a little shorter and more obconic, the
eighth obconic, scarcely forming part of the club; the last three joints wider, produced
on each side; the apical joint about as wide as long, but compressed and contracted at
the tip.
Three specimens from Bugaba agree very closely with the description I have given,
and in size; a fourth is much smaller, and has not the fuscous punctures, but the
strie rather more distinctly impressed; while one specimen, also from Bugaba, has the
elytra rather more produced at the apex, entirely smooth and unicolorous, but with
numerous most minute punctures both in the obsolete strie and irregularly in the
interstices. This species is allied rather closely to B. concolor, but appears (according
to a specimen of that species from Reiche’s collection) to differ from it in having the
thorax shorter, more convex and shining, and (according to Lacordaire’s description) by
the strie and punctures being more effaced.
9. Brachysphenus striatipennis.
Oblongo-ovatus, convexus, flavo-testaceus, nitidus; antennis (basi excepta), scutello tarsisque nigricantibus ;
elytris tenuiter distincte punctato-striatis, striis fere integris, punctis fuscis, Long. 63-8 millim.
Hab. Panama, Bugaba (Champion).
This species is so very near to B. brevicollis that it will suffice to point out-the
differences:—The antenne are thinner; the thorax is not quite so short, and less
convex, and the median lobe at the base is less distinctly produced and truncate ; the
. punctures of the elytral striz are more distinctly impressed; and the legs have only the
tarsi infuscate. B. striatipennis appears to agree very closely with Lacordaire’s
description of B. concolor; but to differ by not having the tibie infuscate, and by the
strie being continued almost to the apex of the elytra. It differs also from the repre-
sentative of that species in Crotch’s collection. |
10. Brachysphenus pallidipennis.
Oblongus, elytris longioribus, testaceis, nitidus, fere glaber; prothoracis disco convexo, rufo-testaceo, lateribus
late et elytris pallidioribus, his fusco punctato-striatis, vix impressis; antennis (articulis duobus primis
exceptis), scutello, tibiis tarsisque nigris. Long. 9 millim.
Hab. Panama, Bugaba (Champion).
This species is exceedingly close to, and difficult to separate satisfactorily from,
B. brevicollis. If, however, great latitude is not to be allowed to proportionate form
in this genus, the longer and rather flatter thorax, and the much longer, more pointed,
and gibbous elytra indicate a distinct species. In three specimens, which seem to
agree in this respect, 1 notice also that the median lobe of the base of the thorax is
very narrowly black at the tip; the tibie are quite black in two examples, in the third:
they are rufous at the tarsal end.

Allied to, and about the same size as, B. ictericus, but in that species the thorax is
not so. short and the scutellum is yellow. Head, thorax, and body beneath of a clear

hardly so long as the head and thorax; in one specimen the second joint is infuscate.

12. Brachysphenus conspicillatus. (Tab. V. fig. 12.)
Ovatus, antice et postice acuminatus, flavo-testaceus ; antennis (articulis duobus primis exceptis), scutello, tarsis
annulisque duobus elytrorum (anteriore obcordato) nigris; elytris confuse punctato-striatis, interstitiis
obsolete punctatis, striis nonnunquam subgemellatis. Long. 8-9 millim.
Hab. Costa Rica (Van Patten), Cache (Rogers).
This insect is rather nearly allied to and resembles B. perspicillatus, Lac., from
Colombia. B. conspicillatus differs in being rather larger, more acuminate before and
behind, and by the curious and generally indistinct rings of the elytra being blacker and
larger, and not united (they are often formed by the punctures at that part being black,
with a blackish appearance under the surface between them); but more especially by the
strie not being so regularly and evenly disposed—there is generally a wide space in the
middle between the fifth and sixth. The anterior ring has an angular projection just
reaching the base of the elytra; the posterior one is nearly round, almost touching the
margin, but it is often open at that part for a short distance. About a dozen examples
have been received from Cache.

black, with the elytra and abdomen dark fulvous-red ; the former punctate-striate,
but with the first four strize only distinct at the base, and all obliterated before the
apex, and those external to the short fifth stria also quite obliterated. The head and
thorax are glabrous; the antenne entirely black. The prosternum is compressed, but
not elevated or pointed, in front. The scutellum is pitchy-red in the San Geronimo
specimen; in two others from Chiacam it is black. B. fulviventris is the only known
species of this convex oval form, acuminate before and behind, with the abdomen red,
which has the strie obliterated externally. In the San Gerdnimo specimen the cox
are red also, but it does not appear to be distinct from those from Chiacam. ©

Very nearly allied to B. rubidus, Duponch.; but differing from it in having the
scutellum black and the upper surface of a less sanguineous-red colour, as well as in
minor details.
The antenne are thinner and have all the joints (especially those intermediate
between the second and the club) longer. The lobe in the middle of the base of the
thorax has its tip black in two examples, viz. in the one from Guatemala, and in
another from Costa Rica, and these have also the extreme limb of the lateral margins
of the thorax and elytra black. The opalescent tint of the prothorax appears to be a
specific character ; but none of the specimens received (there being only one from each
locality) are in good condition.

This species is of a deep but lucid brick-red colour, with black antenne and legs; the
tips of the palpi and the mandibles are blackish, but the coxe are red like the body.
The head and thorax are smooth and shining, the former often with two impressions
between the eyes; the latter narrowing in front, with slightly rounded sides, the
base bisinuate, forming acute hind angles, and the middle lobe separated by a shallow
transverse depression from the disc. Elytra very convex, and a good deal wider in the
middle than the thorax, punctate striate, the interstices a little rough, but the sculpture
obsolete and not distinct, so that the surface is shining. There are no true coxal lines,
but the area over which the middle femora move is faintly indicated by an obsolete
carina. This species is nearest, I think, to B. rubidus, but is more convex. We have
received three specimens from Caldera and one from the Volcan de Chiriqui.

Hab. Guatemata, Capetillo, Zapote (Champion).
The form of this species somewhat resembles that of a Prepopharus; but the
antenne are not so long, being only a little longer than the head and thorax, and they
are pitchy-black with two joints at the base red. The thorax is narrower at the base
than the elytra (which latter widen gradually from the shoulders to the middle); it is
transverse, considerably narrowed in front, and the front margin is almost semicircularly
emarginate ; on each side of the middle are three spots of irregular shape (disposed in
a triangle), and there is one small round spot in the middle near the base; the disc is
obsoletely punctate, and there is an uneven fossa before the hind angles. The
elytra are striate only at the base, where several short rows of punctures are
present ; the humeral lunule is sometimes united with another lunular marking which

turns the reverse way, 7. é€. towards the suture, but both lunules are more frequently
broken into two or more irregular spots; beyond the middle on each elytron are two
squarish spots, placed somewhat obliquely, and an apical undulate fascia. The
underside and legs, as well as the elytral epipleure, are pitchy-red ; all the segments of
the abdomen have a dark spot on each side. ‘The antenne are pitchy-red at the base,
with five or six joints at the apex blackish-brown.

A single specimen, which is, I think, probably referable to this species. I have not,
however, seen any authenticated specimen of B. spectadilis. The Bugaba insect is
black with the abdomen and elytra yellow; the latter with two fascie very narrowly
interrupted at the suture, and not touching the margin, and the apex black. This
insect is somewhat allied to B. venezuele, Crotch.

eighth elongate and widened at its apex, so as to commence the long and lax club.
The head has the muzzle produced rather more than in typical Brachysphenus, and
conical, the antenne inserted in sockets which have a raised, slightly tubercular
ridge above; the crown has an obscure fuscous spot. Thorax twice as wide as long,
glabrous, testaceous, with a fuscous cloud in the middle; the hind angles are acute,
the sides nearly straight at the base, but rounded in front to the front angles, the front
broadly and deeply excised. The elytra are moderately convex and slightly gibbous,

the apex much depressed, without striation, but rendered uneven by obsolete irregular
and feebly impressed punctuation; close to the margin is an impressed line in which are
rather deeper punctures. The fourteen spots are of various sizes, and sometimes one or
two pairs are confluent; there are three basal (the one on the callus the largest), three
subapical, five forming a sort of fascia before the middle (the two inner ones oblong and
adjacent and larger), and three placed transversely between these and the three subapical
ones, Underside and legs testaceous, the knees, tibiee, and tarsi pitchy-black. Allied

Rev. Erotyl., Cist. Ent. i. p. 525; Chapuis, Gen. Col. xii. p. 62 (pars).
Erotylus as restricted by Crotch contains only the species of Lacordaire’s first
division ; his remarks, however, apply to the whole genus as constituted by Lacordaire..
As adopted by me it includes only such species as have the front of the head not
constricted at the point of insertion of the antennz, and the elytra more or less
variegated or entirely black. About sixty-five species have been described, all from.
Tropical America, and the genus is in great part confined to the Southern continent.
Some of the members of this and the following genus bear a very close resemblance
to certain Tenebrionide, e.g. Cuphotes (=Spheniscus) ; and (according to Mr. Cham-
pion) they are frequently to be found together about the fungoid growth on decaying
trees in the forest.

This species is subject to a good deal of variation, and the markings are seldom
symmetrical on the elytra. The numerous examples from different localities now
before me show conclusively that £. confluens, Crotch, is only one of the numerous
varieties in which the black markings are very much reduced in size. The single
specimens from Chontales and from Cache are of a bright orange-yellow with rufous
margins and epipleure, and are very similar to L. nicarague.
The figures 17, 18, and 19 are of varieties of this species from Jalapa; figure 20 is
taken from a specimen of the variety EL. confluens, Crotch, from Purula in Vera Paz.

It seems probable that this is only a local variety of EL. leopardus in which the black
markings are divided into spots by the geminate striz, so that the interstices between
the second and third, and between the fourth and fifth are free from black marks, and
the spots are thus clathrate. I see no other difference, as the bright orange colour is
repeated in aspecimen from Chontales which is certainly H. leopardus. Two examples
captured by the late Mr. T. Belt agree with Crotch’s type.

united to the base; the central lateral spot is also usually, but not always, united to
the margin ; and there is a black dash running a little way up the suture from the

Under this name Crotch included all those species of Lacordaire’s genus Erotylus
which have the front of the head coarctate, the elytra with black impressed punctures,
and the thorax margined at the base. ‘Many of the species are remarkable for the
way in which their elytra are elevated. This genus attains a higher degree of latitude
than the true Hrotyli, several species being found in Mexico, and one or two passing
the Rio Grande, while comparatively few are known as existing south of the Amazons.

Two specimens, which I refer with some doubt to this species, only differ from
examples in Crotch’s collection in the central and lateral black spots on the elytra
being united and forming a broad fascia, indented on the basal side. In form they
agree precisely with others from South America; but they are rather larger than the
average. Considerable doubt exists as to what species should be referred to the Chryso-
mela gibbosa of Linneus; the description, however, agrees with the form here recorded.

C. jansoni, Crotch, differs in nothing from C. vicinus but in the more reduced black
elytral spots, which in the present species often form an interrupted oblique fascia ;
and both are so very nearly allied to the Colombian C. gory that I see no more
important distinction than a further extension of the black fascia, so that its oblique
disposition is lost. They are probably only local forms of one species.

Hab. GuatemMaua!, Las Mercedes, Cerro Zunil, Zapote, Mirandilla, San Gerénimo,

The distinguishing character of this species is the narrow lateral rufous margin of the
thorax. The elytra have their black markings, especially the apical one, more developed
than in C. vicinus ; but I do not see any difference in their convexity, and the size of
the black punctures is very variable. The male characters are:—the widened front
tarsi, thickened front femora, and pilose dot on the ventral basal segment; the thorax
scarcely differs, and the front tibiz are very little bent or compressed. A few examples
were found in each locality.

There is no known species with which this can be very well compared. The form is
that of C. boisduvali, but no other species of that group with the hind femora ringed
with red is known to me; the rings are similar to those of C. annulipes, though rather
wider. The single specimen received is a male, and the thorax is wide and formed
almost as in the male of C. boisduvali, but the elytra are shorter.

The elytra in this species are convex, even, with largish, not very numerous, black
dots; their colour is ochraceous. The thorax is uneven, with two oblique fovee on
each side, and a deep transverse one at the base. ‘The elytra are more firm in texture,
and more shining than in the following two species; the suture is finely raised, but
there is not a stria. We have received a large number of examples.
The true C. bovsduvali does not occur in the United States; the species thus
identified by Crotch (Trans. Am. Ent. Soc. iv. p. 3858), is described below under the
name of C. aspersus. The variety might perhaps be now restored to specific rank, but
the number of examples in the collection before me is hardly sufficient to enable
CYPHEROTYLUS. 107
me to decide the point. The thorax, nevertheless, is always more opaque in
C. californicus (Lac.) ; and in.the male the sides are very strongly rounded.
One specimen from Jalapa, which I refer to this variety, differs, however, so much
from the usual form of it as greatly to invalidate these distinctions.
The figure is of a female specimen from Jalapa.

This insect is perfectly distinct from C. boisduvali, and also from its variety C. calt-
fornicus (Lac.). It is longer and the elytra are notably more depressed, so that the
contour when observed laterally is much less arcuate. The surface of the elytra
between the black dots is also sculptured with a fine irregular but alutaceous punc-
turing.

Hab. Mexico, Refugio, Ventanas in Durango (Hoge).
Similar to C. alutaceus in form. On the elytra the black dots vary in depth and
size, being more confluent in some examples than in others ; the lateral spot is sometimes
confused, and it is composed of three or four confluent dots only. The thorax in the
male has its sides a little more rounded than in the female, in which sex the sides are
nearly straight though narrowing towards the front; the disc is almost opaque; the black
spots are slightly notched on their front and posterior sides, and in the single example
from Ventanas this notch is so deep that they are almost divided. The prosternal process
is edged with black. The elytra are very pale, almost whitish-yellow, and not shining,
but are scarcely alutaceous, though faintly rugose between the black dots; the latter
in some examples are so numerous as to form confluent patches, while in others they
are nearly all distinct.
This distinct new species was discovered by Herr Hoge during his second Mexican
expedition; we have received fifteen specimens from Refugio and one from Ventanas.

Very closely allied to C. fenestratus, but with the thorax black. Both species are at
once separated from C. boisduvali by the depressed and apparently always soft elytra,
by the small trapezoidal thorax, and by the whole insect being dull. I have not seen
a male which I can refer to this species. The specimens from Colorado in my collec-
tion were received under the name C. boisduvali, but they are not referable to that
species.

Micrerotylus, Crotch, Cist. Ent. i. p. 541 (1876).
The species which Crotch took for his type of this species, viz. I. gronovit (Herbst),
was placed by Lacordaire in Brachysphenus, in the section Barytopus, with other
members of which, however, it has little connection. The six species included by
Crotch have a very similar form and mode of pattern, and one or two are doubtfully
distinct as species. There is nothing but general form and style of pattern to separate
them generically from either Brachysphenus or Erotylus; and they approach very
closely to some Zonarii, such as Z. indicus. They are all from Tropical South America,
from the Amazons northwards, and one species occurs in Central America.

Zonarius is separated from Erotylus by very trifling differences of structure, and it is
impossible to give any definite reason for its distinction from Micrerotylus. Yet there
is a peculiarity of pattern and a similarity of form among the species which render
its members easy of recognition as pertaining to a distinct natural group. About
twenty species are known, all from Tropical South America and Central America, but
not passing further north than Mexico.

A well-known and widely distributed species.
Z. quadrifasciatus is only a variety with the bands on the elytra rather narrow.
The specimens we have received from Zapote agree perhaps more nearly with
Z. jansoni than with Crotch’s type of Z. guatemale ; but serve to show that the forma-
tion of species on mere colour-varieties, especially when few specimens are available,
leads to no settled result.

This insect is probably a local variety of Z. zebra. We have received an extensive
series of specimens of Z. jansont; Mr. Champion met with it frequently on the
Volcan de Chiriqui, up to an elevation of 4000 feet. These Chiriqui examples agree
in having the anterior band interrupted so as to form an oblique oval spot on each
110 | EROTYLID.
elytron, yet vary very much both in the width and form of the second band. Others
from Costa Rica have this band very narrow and sometimes undulate, and these
represent a distinct variety.
We figure two examples, one from Bugaba (fig. 15) and one from Cache (fig. 16).

Scaphidomorphus (div. 1), Lacordaire, Monogr. Erotyl. p. 481.
Chapuis, adopting Erichson’s name Prepopharus for the second and third divisions,
restricts this genus to two large species which have their prosternum with a keel and
the labium emarginate.
Crotch seems to have regarded these two species as forms of one variable insect ;
Gemminger and Harold, on the other hand, retain them as distinct. I have not seen
specimens of 8. 5-punctatus from Central America.

This is a large and showy species, varying very considerably in size (one example
from Chiriqui measuring only 13 millim., while others reach 20 millim. in length), and
also in the dimensions of the red spots. The second spot is more or less divided, and in
several specimens from Bogota (in Crotch’s collection) forms only two small spots; in a
singular variety in my own collection the internal one only of the two spots remains.
The colour of the spots also varies from blood-red to pale yellow.

Mexico being the northern limit of the genus.. The species have frequently an opaline

This species is very variable, especially in the markings on the thorax: these normally
consist of four black spots—a transverse one in front, just touching the margin, two
lateral oblong ones, and a median one on the base—but these are varied, divided, and
united in every conceivable way. In the Mexican examples the disc of the thorax is
often dark, and the front and lateral margins yellow; but even then the disc shows
some traces of the divisions between the typical spots. Many examples.
We figure a variety from San Andres Tuxtla and one (more typical) from Caldera.

Hab. Panama, Bugaba (Champion).
This insect has very close relationship with some Brachyspheni; but from the scaphi-
form shape of the body beneath I think it belongs here. The strie are somewhat
gemellate, ¢.¢. the second and third and the fourth and fifth, and these pairs approach
at the apex; but at the base of the elytra the first (or sutural) stria unites with the
second, and the third with the fourth.
Five specimens of this interesting species were captured by Mr. Champion.

surpassing, those of the Scaphidomorphi and Prepophari. The elytra are at the same
time very parallel, and often have their apices truncate or even serrate, and are some-
times spotted with black in a peculiar manner. One or two of Lacordaire’s species, as
Crotch remarks, do not seem to belong to the genus; but Crotch has himself added
fifteen species, very few of which I can recognize as Prioteli. A few have been
described by Erichson and Kirsch. Altogether, of true Prioteli, about twenty species
are described. They appear to be almost exclusively confined to the tropics of South
America; but one species, originally described from Mexico, is distributed all over
Central America, and, according to Lacordaire, extends its range to Colombia.

Numerous specimens of this species have been sent; these vary in length from seven
to twelve millimetres. In most examples the thorax has two dots in front and one very
small one immediately before the scutellum on the base; but in some, as in those
from Chontales, it is spotless. P. apiatus is very like P. tigrinipennis, Lac., from
Colombia ; but differs from it in the apex of the elytra being entire, instead of being
obliquely truncate. I have not seen examples of P. apiatus from south of the Isthmus
of Panama, and its presence there is doubtful. An individual from El Reposo is figured.

pp. 150, 559.
Homeotelus, like Priotelus, is distinguished among the ‘ Erotylides’ by its long, thin
antenne ; but is separated from it by its more or less scaphiform body, acuminate in
front and behind, and by the small head with small eyes.
The elytra are never spotted, but are red or dark with the margins and suture lighter ;
in one instance the suture is produced in the middle into a remarkable spine. Lacordaire
enumerates nine species, but in Crotch’s catalogue the number is brought up to twenty-
two; and several others undescribed as yet are known tome. Priotelus limbatus, Crotch,
from Guayaquil belongs here, The distribution is the same as that of Priotelus, but the
species are more numerous. We have received four species from Central America.

The numerous specimens now before me show that this species is not so nearly allied
to H. testaceus as the above diagnosis would lead one to suppose. It is much more
difficult to separate it satisfactorily from H. wmbonatus, Lac., and H. hepaticus, Crotch.
The colour is very variable, it being sometimes as dark as that of H. umbonatus ; but
the thorax has never more than faint shades in the place of the vittee, and the scutellum
is not dark as in H. umbonatus. The antenne, however, in H. confusus are entirely
black at their apices. Crotch alludes! to specimens from Venezuela which have the
femora entirely yellow; these are not in his collection, and they may be specifically
distinct. A specimen from Bugaba is figured.

A great number of specimens of this insect have been sent ; these show considerable
disparity in size, and some difference in form and sculpture. The largest examples are
those from Costa Rica, several of these being 14 millim. long, and the smallest are some
from Capetillo (8 millim.). These latter very much resemble H. jansoni, but may be
known from it by being less convex and with the margins of the elytra a little more
reflexed, and also by the interstices of the striz being flat and not so deeply and less
thickly punctured. :
Many of the larger examples have the elytra with an expanded production at the
tips, but I cannot ascertain that this is a sexual distinction.
Lacordaire ! also gives Mexico as a locality, but I have no doubt that his specimens
from that country belong to the following species. |

The elytra are of a sordid pale yellow, with the suture darker, and the reflexed
margin pale, the head and prothorax and body beneath being of a rufo-testaceous
colour; the antenne are black with the two basal joints clear red ; and the femora are
red, with their tips and the tibize and tarsi black. The specimens from Sinanja, two in
number, agree precisely with the others, except that the series of punctures are a little
more deeply impressed, and the interstices are more distinctly punctured. The example
from Chiriqui, which we figure (fig. 24), is very different in colour, and should perhaps
be considered a distinct species; but it agrees very closely in form and punctuation with
others from Mexico.
Lacordaire did not (according to Crotch) distinguish this species from H. gemeliatus,
and it is therefore to this species rather than to H. gemellatus that his quotation—
“des provinces orientales du Mexique,” refers.

CORYNOMALUS. 115
Fam. ENDOMYCHIDZE.
The passage to the Endomychide from the Erotylide through Hom«otelus seems
natural enough, and some species of Brachysphenus, such as B. festivus, have quite the
facies of the present group. The family, however, is concisely separated by the tarsi
having one less apparent joint ; while certain genera which have been admitted, part
of which form the ‘‘ Endomychide adsciti” of Gerstacker, will here be treated as
equally aberrant from both families, the foot-structure in these showing very important
differences.
The genera of Endomychide inhabiting the New World are more differentiated from
those of the East than is the case in the Erotylide. We altogether miss here any
representative of the Humorphi or Spathomeles, while Corynomalus is equally the
special form of Tropical America, and the former accordingly form a subfamily
unrepresented in our fauna.
The family is somewhat more specialized, but on the other hand its representatives.
are far inferior in number, both in genera and species, to the Erotylide. The Pale-.
arctic and Nearctic zones and low Southern latitudes possess few and feeble forms; as.
a group, they area tropical development of a peculiar type that has never been dominant,
dependent on special circumstances for their existence, and therefore rare in nature.

Mulsant recognizes four varieties of this widely dispersed and sometimes very
abundant species. Thus :—
Var. A. Elytra without spots.
Var. B. Elytra with the scutellar spot only.
Var. C. Elytra with a scutellar spot, and some spots in addition to the normal pattern.
Var. D. Elytra marked with black spots irregularly placed.
The var. B is rather common; we have seen it from Guanajuato, Oaxaca, Etla,
Puebla, Cordova, Tenango del Valle, and Amecameca. But a variety in which the
scutellar spot is wholly absent is not among the very numerous specimens that have
come under my notice; nor have I seen varieties corresponding to vars. C or D, with
more than the normal number of spots, that is to say three basal and three apical
spots on each elytron besides the very small scutellar dash on the suture. Varieties in
which one or all of the three basal spots are wanting or reduced to points are common.
Subfam. COCCINELLIDES.
This subfamily contains really only the two genera Adalia and Coccinella, for
Mulsant’s Adonia is by most authors now generally merged in Hippodamia, and
the genus Cisseis, containing but one species, has been shown by Crotch to be a
Verania. esis, Mulsant, has no character whereby it can be separated from the
Halyziides, and Bulea is only separable from Coccinella by having simple instead of
“ appendiculate ” claws.
The only question now is whether it is worth while maintaining the Halyziides in a
separate division, or as a subfamily at all.

The differences proposed for the separation of Harmonia are not satisfactory, nor
sufficiently constant to render such a partition of the genus of any practical value. As
thus constituted, Coccinel/a includes about sixty-five species, which are chiefly confined to
the northern temperate zone; a few species are tropical, and New Zealand and Australia
have one each.

Crotch remarks? that this species is “closely allied to C. pieta.” The markings on
the thorax are similar, viz. five wedge-shaped dots—three on the base and two above—
forming an M-shaped mark. In Crotch’s specimens the spots are confluent or (in the
type of quinquelineata) confused in two lateral groups, with three central ones forming
the point of the M-like mark. |

Mulsant’s types of Harmonia ampla and H. soularyi are now before me, that of
H. ampla* being included in the Crotch Collection at Cambridge. ‘They are specifically
identical, there being scarcely any d fference even in the number of spots; in the typical
form the second transverse band does not show any trace of the fourth spot nearest the
suture, this spot even in C. soularyi being often evanescent. There is no difference in
punctuation, form, or structure. Mulsant must have forgotten the original type when
he described this as new from M. Sallé’s collection. The species has very much the
markings of Cycloneda abdominalis (which Mulsant has redescribed, Monogr. p. 64,
under the name of Harmonia V-nigrum); but is more depressed, and has the closely
punctured, alutaceous sculpture of Harmonia.

As might be expected in such a widely distributed species, a good deal of variation in
size and marking occurs. The Siberian and Greenland specimens often have the scutellar
spot united with the humeral one, forming a transverse band; but examples occur in
Siberia with the spots detached, as they usually are in the specimens I have seen from
North and Central America, and then they so much resemble C. novem-notata as to be
frequently confounded with it. C. ¢ransversoguttata may, however, be distinguished
by the head having the front and the labrum almost entirely white, and by the front
margin of the thorax being narrowly edged with the same colour. Other fine distinc-
tions are also present. It is less ovate, and the surface of the elytra is scarcely
perceptibly punctate, even when viewed under a Coddington lens. The species is
common at times, and Herr Hoge obtained a good series of it at Las Vigas.

I include this North-American species on the authority of Mulsant’s works. It is

confirmation. |

in his collection. .
C. franciscana is a variety with the elytra without spots (excepting the scutellar one)
parallel to C. californica. :
11. Coccinella cyathigera. (Tab. IX. fig. 3.)
Oblongo-ovata, lutea, subtus cum pedibus rufo-piceis; prothorace subtilissime punctato, macula discoidali
M simulante, interdum interrupta vel e maculis distinctis formata, nigra; elytris creberrime fortius
punctatis, punctis uno in collo humerali, tribus paullo ante medium fasciam prebentibus, duobus pone
medium suturaque tenuissime rufo-piceis. Long. 5 millim.
Hab. Guatemata, Quiche Mountains 7000 to 9000 feet, Quezaltenango 7800) feet,
Calderas 7000 feet (Champion).
The general colour of the upper surface is pale luteous-yellow; the head bears a_
double black spot at its base, usually concealed by the thorax. The thorax is trans-
verse, not deeply emarginate in front, the front margin straight ; the sides moderately
arcuate, narrowing in front, faintly reflexed. Scutellum black, punctured. Llytra
very thickly punctured, and the sculpture quite visible under an ordinary lens of one
and a half to two inches focus, scarcely margined; the spots ordinarily very small,
placed—1 humeral, 3 fasciate (the one near the suture and the external one a little
nearer the base than the middle one), and 2 at one third before the apex,—the suture
very narrowly rufo-piceous. The underside and legs of a pitchy-red colour, the breast
and head being of a deeper tone than the episterna and abdomen.
In about a dozen examples of this species there is no variation in the number of
elytral spots nor any trace of additional ones. The prethoracic M-shaped mark is very
clearly defined ; its upper angles are upon the front margin; its middle is formed by
a prolongation of the junction of the oblique lines, so as to form a Y when detached
from the side lines; the bases of the side lines are in the form of triangular spots on
the base, sometimes detached. ‘This insect has much the appearance of various other
species, as the European C. variabilis, Psyllobora configurans, Cycloneda abdomi
nalis, &e.
12. Coccinella albo-picta. (Tab. IX. fig. 4.)
Oblongo-ovata, nigro-picea, nitida, capite prothoraceque albis, hoc disco macula M latum simulante, interdum
interrupta, punctoque laterali; illo basi binotato, punctisque nonnullis in epistomate notatis; elytris
singulis maculis quinque albis—una basali, juxta scutellum, una discoidali juxta suturam, tribus late-
ralibus, seepissime conjunctis ; prosterno et epimera mesosternalis albis. Long. 3-33 millim.
Hab. Mexico, near the city (Hége); GuatemaLa, San Gerénimo (Champion).
Only five specimens of this species have been sent, four of which are from Mexico city.
It is of a puzzling aspect, looking as if it might be a variety of some other species,
but it is, I believe, quite distinct. C. albo-picta seems to come nearest to C. areata,
Muls., a Bolivian insect. The head is white, with the base marked, as is so often the

case, with a double spot, concealed by the thorax, the epistome often with a V-shaped
spot; the mouth-parts are yellow. The thorax is about twice as wide as long, smooth,
and impunctate, the front margin straight with the angles prominent and deflexed; the
markings consist of a broad M—this in the darker individuals may be a broad patch
enclosing two angular white spots, or may be composed of five or more spots, variously
united in different specimens, but it never quite reaches the front margin, and the two
triangular spots on the base are always distinct; sometimes an additional “lateral ”
comma-like spot is joined to the sides of the M. The elytra are only very finely and
obsoletely punctured; they are pitchy-black or pitchy-brown; the humeral and apical
white marks are elongate, following the margin, and narrowly joined to the middle
lateral spot, so that the whole margin with the epipleure is white; the discoidal
white spot may be joined to the lateral median one, forming a broad fascia, and occa-
sionally it is united with the anterior one so as to form a common discoidal spot in the
less deeply coloured specimens. ‘The legs are yellow. |

mediana, ad suturam herente, tribus subapicalibus, fasciam obliquam undulatam prebentibus, nigris :

Hab. Mexico, Oaxaca (fége)}.
The features by which this insect may be recognized are :—The rather flat depressed
form, like that of C. venusta; the dark red-brown colour; and the seven thoracic spots
—the two upper ones large and wedge-shaped, the two lower ones (or those repre-
senting the lower branches of the M) also large, and for the most part separate from the
upper, the middle one in the form of a dot, a little above the base, the two lateral ones
in the ordinary position. The elytra have spots of a deep blackish-brown colour :
the two discoidal or middle ones are large, joined to the brownish suture by a recurving
streak (somewhat as in C. venusta); the two lateral spots are a little behind the two
basal ones, and are elongate, and either very narrowly divided or united; of the three
subapical spots, the external two are confluent in both of the two examples obtained,
forming an undulate V-like mark, and are also just in contact with a square sutural
spot (which, however, would obviously be often detached); the punctuation is distinct
under a Coddington lens, but is very close and fine ; the entire limb is very narrowly
brownish; the margin is hardly at all expanded.
‘This species would, I think, be best placed next to C. venusta, on account of its flattish
form and the style of marking. I have only seen two specimens.

margineque apicali nigris pernitidis; antennis pedibusque rufis. Long. 33 millim.
Hab. Guatema.a, Totonicapam, San Gerdénimo (Champion).
The short and rather convex form of this insect is somewhat suggestive of Brachyacantha,
and it a little resembles B. lepida in pattern. There is a slight metallic appearance in
the black pattern of the thorax and elytra. The head is white and spotless, the eyes
rather large. The thorax is very short at the margins, longer in the middle (as the basal
margin is arcuate), and has the sides strongly deflexed ; the black pattern of the disc is
divided by a middle line, and is notched opposite the front angles so as to form a square
spot there. The elytra vary a little in pattern in the two specimens before me—the
one from San Gerénimo has two large transversely squarish spots on the suture united
by the black sutural line, and a large and rather angular spot occupying the callus, and
on the margin, nearly opposite the hinder sutural spot, is a small spot (this being double
in the Totonicapam example); the apical margin is less distinctly black, and in both
specimens only as far as the lateral spot.
This is an exceedingly neat, pretty species. It is difficult to compare it to any other
I have seen without fear of misleading; the markings are somewhat suggestive of those
of Propylea conglobata, but the insect is more convex and more shining than that species.
The Totonicapam specimen is figured.
15. Coccinella concinna.
Oblonga, depressa, subobovata, albida, subtus nigro-picea ; capitis basi et epistomate, prothoracis lineis duabus
ad basin ampliatis, marginem anticam haud attingentibus, scutello, sutura, macula pone medium fasciiforme
et nonnunquam duabus alteris parvulis, una in callo humerali, una quam hee paullo posteriore nigro-
piceis; elytris creberrime obsolete punctatis; pedibus luteis. Long. 34 millim.
Hab. Panama, Volcan de Chiriqui 8000 feet (Champion).
This little species has the form of Adalia, but at present I prefer associating it with
C. compta, to which it bears some resemblance. The sides of the thorax are evidently
rounded and contracted in the hind angles, so as to form a break in outline with the
elytra. The margins of the thorax and of the elytra are moderately expanded and
reflexed. ‘The elytra are widest behind the middle opposite the larger spot; this latter
is of an irregular form, but indicates an oblique fascia nearer to the base at the margin
than at the suture (in none of the three examples before me does it reach either); in
one example the two smaller spots are wholly wanting, they are both submarginal, the
first actually on the callus; the sutural pitchy-black line vanishes near the apex, where
the limb alone is pitchy.
The body beneath is black, smooth, and not punctured; the mesosternum has a
shallow impression for the reception of the prosternal process; the coxal depressions
on the first ventral segment are ill defined, the lines proceeding from the intercoxal
process being shortened and not touching the hind margin of the segment. The middle
and hind femora have a dusky cloud in the middle.

16. Coccinella pantherina. (Tab. IX. fig. 9.)
Breviter oblongo-ovata, convexa, lutea, nitida, capitis basi maculaque duplici epistomatis piceis; prothoracis
disco nigro, margine antico et laterali (ad angulum anticum latiore) lineaque mediana basin haud attingente
luteis ; elytris sutura late, margine apicali tenuiter, plagia suture parallela in medium desinente, macula
oblonga pone medium suture conjuncta, et tribus lateralibus irregularibus, attamen distinctis, una in callo
humerali cuneiformi, nigris; pedibus luteis. Long. 23 millim.
Hab. GuatEmaa, Totonicapam 10,000 feet (Champion).
This little species is of about the size and form of Brachyacantha lepida. The black
markings of the elytra are developed so as to leave only a reticulate yellow pattern,
and the puncturing is hardly visible, except under a Coddington-lens. ‘The body
beneath is pitchy, with the exception of the abdomen, which is luteous. Two specimens
were captured in the pine-woods at Totonicapam.
17. Coccinella quichensis. (Tab. IX. fig. 10.)
Breviter ovata, lutea, elytris creberrime vix visibiliter punctatis ; capitis basi, epistomate, prothoracis signatura
litteram Y simulante, maculisque duabus basalibus nigris ; elytrorum sutura plagiisque quatuor (interioribus
vittam interruptam prebentibus) exterioribus, his parallelis sed punctiformibus, nigro-subeneis ; corpore
subtus pedibusque rufis. Long. 4 millim.
Hab. GuateMaLa, Quiche Mountains 7000 to 9000 feet (Champion).
This is a broad, rather squarely built, depressed species, the markings of the thorax
somewhat suggestive of those of Chilomenes. Only one specimen has been received, and
the figure will convey a better idea of it than a long description.
18. Coccinella ——?

I have retained it as a convenient temporary working division, mainly distinguished
by the less convexity of the species, their longer antenne, and some other quite unim-
portant characters which are partly common to other groups. But I am unable to
discover any real ground for separating it from the “ Coccinellides,” or of any one
character that will distinguish it.
MYSIA.
Mysia, Mulsant, Hist. Nat. Col. Fr., Sécurip. p. 128 (1846) (nomen przeocc.).
This boreal genus consists at present of four species found where Conifere are
abundant; the only species known from Central America was referred to Pelina by
Mulsant, probably owing to its having the margins of the elytra widened. This
species is not represented in our collections, and, indeed, its precise origin is doubtful.
It is very probable, however, that the genus occurs in high altitudes in Northern
Mexico.

HALYZIA.
Halyzia, Mulsant, Hist. Nat. Col. Fr., Sécurip. p. 148 (1846). |
Halyzia, in the restricted sense used by Crotch in his ‘ Revision,’ contains only five
species. In the Munich Catalogue, on the contrary, fifteen of Mulsant’s genera and
four of Crotch’s are sunk under this name; and it is there made one of the largest
aggregates in the Coccinellide, containing more than one hundred very diverse species
from all parts of the globe.
The proper definition of this and other genera has yet to be made. One of the
species I propose to refer to Halyzia is allied to the type of the genus, ZH. 16-guttata,
by its slightly widened margins, by the form of the thorax, which has the sides thin

and expanded, with round posterior angles, by the mesosternum having no fossa in the
middle of the front margin for the apex of the prosternum, by its longish legs, &c. ;
but in other points, as its round and convex form, it superficially resembles Cycloneda
abdominalis. While I do not feel at present able to offer systematic characters for the
reconstruction of the genera of this group, I think the presence or absence of the
mesothoracic fossa (which is much more than a mere emargination) will prove of far
greater value than the character drawn from the abdominal coxal fossa, “ plaque abdo-
minale,” which seems to me to be very vague.
1. Halyzia emaciata, (Tab. IX. figg. 12, 13.)
Pallide testacea, fere albida, prothorace lineolis duabus basalibus, elytris Junula parvula juxta medium
suturee punctisque duobus submarginalibus brunneis; elytris creberrime, obsoletius, subconfluenter punc-
tatis. Long. 3-43 millim.
Hab. Panama, Volcan de Chiriqui 2000 to 6000 feet (Champion).
Head in repose quite covered by the front of the thorax, which, being almost
translucent, permits the eyes to be seen through it from above; front margin of the —
thorax not emarginate; antenne moderately long, all the joints longer than broad,
the terminal ones fully thrice as long as wide; the tarsi and the extreme basal
margin and suture of the elytra very narrowly brownish. ‘The elytral spots are very
indistinct; in one example, however, the sutural lunules are united and form a
common spot. Viewed laterally, the outline of the elytra from the base to the apex
is gibbous. .
About a dozen examples of this obscure and very plain-looking species were obtained
by Mr. Champion at various altitudes above 2000 feet on the slopes of Volcan de
Chiriqui. .
2. Halyzia epistictica. (Tab. IX. figg..14, 15.)
Oblonga, albida vel albo-testacea, prothorace maculis tribus oblongis, elytris singulis maculis nonis guttiformibus,
2, 3, 3, 1 dispositis,. brunneo-testaceis, creberrime obsoletius punctatis. Long. 5-6 millim.
Hab. Guaremata, San Gerénimo (Champion); Panama, Volcan de Chiriqui 2000 to
3000 feet (Champion). |
This insect is more clearly of the form and structure of H. 16-guttata than is
H. emaciata. The thorax is much narrower than the elytra, and is shining and
diaphanous at its margins; the front is not excavated and conceals the head, the
eyes showing through. ‘The elytra are shining, and only seem to be punctured when
seen under a quarter-inch lens; in one of the two Guatemalan specimens they are
white, in the other and in the Chiriqui example they are of a bright but pale yellow.
The spots are, for the most part, elongate streaks pointed at their lower end, or at
both ends; the three thoracic spots are irregularly triangular; of the elytral spots, two
are basal (the internal one more elongate than the external one), and the internal or
HALYZIA.—PSYLLOBORA. 165
sutural one of the succeeding three is hooked outwardly and recurved towards the
base on the sutural side—this spot is usually detached from the suture, but in one
example it forms a common pear-shaped spot on the suture.
We have received three examples of this species, two of them being from San
Ger6nimo. A specimen from each locality is figured; the one from Panama is rather
smaller than the Guatemalan representatives.
8. Halyzia championi. (Tab. X. fig. 1.)
Oblonga, lete, dilute flava; prothorace quam elytra multo angustiore, basi punctis duobus nigris lateribus
modice explanatis et reflexis, subdiaphanis; elytris creberrime minute punctatis, singulis punctis novem,
2, 3, 3, 1 dispositis, nigris. Long. 43 millim. .
Hab. Panama, Volcan de Chiriqui 8000 feet (Champion).
The sides of the thorax converge towards the front, but are considerably rounded at
the hind angles; the front margin is almost straight, and the head can be retracted at
least as far as to hide the eyes beneath it; the base is sinuous, and is marked with two
round dots (like those in the Eastern Thea cincta), and this character alone will distin-
guish H. championi from any Halyzia known to me. Of the elytral spots, two are near |
the base, one of them being on the humeral callus, and one between it and the suture ;
then three almost in a straight row, but the inner one a little nearer the apex than the
others, then three in a chevron; and one subapical small dot. In the number and
position of the elytral spots the species resembles Neohalyzia perroudt.
Only one example of this pretty Halyzia has been found, which I dedicate to its
captor, Mr. G. C. Champion.
| PSYLLOBORA.
Psyllobora, Mulsant, Spec. Col. Trim. sécur. p. 166 (1850) ; Monogr. Coccin. p. 126.
Psyllobora is, as Crotch has remarked, the New-World representative of Thea. Itis.
simply a convenient geographical division, several species of Thea, e.g. T. vartegata (from _
St. Helena and Africa) &c., being absolutely conformable to the type of Psyllohora,
and some others having the expanded margin of typical Halyzia. The Psyllobore are,
however, generally to be distinguished by the style of marking; and among them are
found the smallest species of Coccinellide, not exceeding the smaller Scymni in stature.
. About forty species are recorded by Crotch, chiefly from the South-American continent,
one or two species only being found in the United States. .
According to Mr. Champion some of the Psyllobore are found commonly on
orange-trees.

Janeiro (Fry °).
Two specimens from the Volcan de Chiriqui agree so nearly with one of Mr.'Fry’s
examples from Rio Janeiro now in Crotch’s collection, that I hardly think they can
represent more than a local variety of the same species. They are smaller, the ground-
colour of the elytra is a bright “ gamboge ”-yellow (indicating that they were freshly
emerged from the pupa when caught), and the markings are rich brown, or chestnut-red.
The posterior spot on the elytra is rounder than the corresponding one in the exponent
of P. germari alluded to. :

- Smail examples of this species come very close to P. 20-maculata. It may, however,
be generally distinguished from that species by being larger, of a whiter colour, by the
spots being less confluent, and by having a small basal spot external to the two large
ones just below the humeral callus. Mulsant describes! the thorax as having only
four spots; but he had only one example, in which the two central spots were probably
united. ‘There are five spots, distinctly separated in the great majority of specimens,
-PSYLLOBORA. | 167
and our examples agree absolutely with the type of P. tardigrada now in Crotch’s
collection. Two spots near the centre of the elytra unite so as to forma kind of paren-
thesis € D, and the upper end of this mark is often united to a spot near the suture,
which then on the right hand forms a rough figure of 5. |
We have received many specimens. The figure is taken from one from Guanajuato.

Bugaba (Champion). |
This little species, which is widely distributed in the Northern continent of America,
is very variable both in size and in the degree to which the markings are confluent.
It may be generally distinguished from its nearest allies by its small size (one of the
Belize specimens :is about 1°5 millim. only in length), by the presence of only two basal
spots (which are rather larger than the corresponding spots in P. luctuosa), by the two
central and two subapical spots often being united to form a broad letter z, and-by the
thoracic spots being often united in the longitudinal direction (which they are not in
_ P. luctuosa). Often the elytral spots are all united, and P. ¢edata is a variety of |
this class.
_ It is probable that some other so-called species are but local varieties of this insect.
Both this and P. luctuosa occurred together at Aceituno.
According to Crotch ®, the locality “ Colombia” quoted by Mulsant * * belongs to
P. liliputiana. Boheman’s locality Tahiti? is in all probability incorrect.

CLEIS.
Cleis, Mulsant, Spec. Col. Trim. sécur. p. 208 (1850) ; Monogr. Coccin. p. 148.
This is a most unsatisfactory genus, consisting of three species, which, according
to Crotch’s collection, seem to have little to do with each other. The characters,
moreover, given by Mulsant, depending chiefly on the degree of emargination of the
prothorax in front, are absolutely valueless. (leis lynx, however, is a more elongate
and depressed form than any Psyllobora, and reminds one of Anisosticta. What
Mulsant says of the mesosternum, “a peine échancré,” applies equally well to Thea or
Psyllobora, besides being vague and unmeaning.

Convexa, subhemispherica, fere levis, pallide albo-flavescens; prothorace vitta lata, elytris signatura reticu-
lata brunneis, areolas in singulis septem includente, duas basales, duas postmedianas, duas transversas
apicales, unam discoidalem subquadratam. Long. 6 millim.
Hab. Panama, Volcan de Chiriqui (Champion).
The pattern of the elytra of this species is very elegant. The brown reticulate line
is thin, except where it crosses the suture below the basal aree. The ground-colour is
pale whitish-yellow, the pattern red-brown. The thoracic vitta is narrowly bordered
with darker brown, and the entire limb of the thorax and elytra is narrowly brown. In
one of the two specimens the apical transverse areolet is united with the large semi-
circular lateral one; but in the other, which we figure, the two are quite separate.
The two large postmedian aree may be termed “ common’”’ to the two elytra.

so narrowly black as scarcely to be noticeable, and the legs are pale.

Mulsant has described what seems to be the less abundant variety first, though he
does not mention the green colour: this fades to a dirty yellow; but in some specimens
it is well preserved, as in the examples in Sallé’s collection and in several of those
collected by Mr. Champion. _ |
Mr. Champion obtained a very large series of the typical C. rubida at Bugaba.

Crotch seems latterly to have regarded this insect as the black form of C. abdominalis ;
it is so placed in his “ Revision of the Coccinellide of the United States,” Trans. Amer.
Ent. Soc. iv. p. 372 (April 1873). In his general “‘ Revision,” however, he remarks ”, ‘I
do not know its pale form”; and, considering the blood-red colour of the elytral spot
and the total absence of intermediate varieties, as well as the fact that among the large
series of C. abdominalis we have received there is not one specimen varying in this
direction, I do not think they can be so united.
Crotch? refers this insect to the C. oculata of Fabricius; it ought to be observed,
however, that Fabricius’s words, “Thorax ater, nitidus, utrinque macula magna, ro-
CYCLONEDA. 173
tunda, marginali, albida,” do not apply to this insect, which has the thorax narrowly
margined with white in front and just round the hind angles, the white margin often
with three linear denticulations in front; also that it is described as a little larger
than C. cacti.

The unique type is now before me from Sallé’s collection. The locality “ Colombia”
seems to be an error of Mulsant’s 1, and Crotch following him does not seem to have
seen the insect. A second error is that Crotch says?, “elytra each with ten spots:”
this is due to a misprint in Mulsant’s description, where ‘‘ dix” is printed for “ six,” as
may easily be seen by the context.

Hab. Guatemata (Sallé), San Gerénimo (Champion).
This species is evenly but not very strongly convex, the margin of the elytra a little
expanded. The head is white; the antenne and palpi yellowish. The thorax is black
in the middle, this colour extending narrowly along the base on each side of the rather
wide central vitta; the extreme apex of this vitta is, however, whitish. The base of
the elytra is yellow for about a quarter of their length, but more widely so a little ©
before the margin than at the suture. In one of the two examples before me the entire
limb of the elytra is black; but in the one from Sallé’s collection the black margin
ceases at the shoulders and at the apex. ‘The legs are black; the tibie on their
internal sides and the tarsi are fuscous. :
This species might almost be placed with Neda, but it has the elytra less expanded
than in XV. marginalis. |

genus can at present be separated from Cycloneda; as restricted by Crotch it includes
about eight American species.

Crotch quotes? Brazil, but with doubt. I have seen no specimens of WV. marginalis
from the Southern continent. The locality of NV. flavens was unknown to Mulsant 4°.
Subfam. CHILOCORIDES.
This is one of the most natural divisions of the Coccinellide, well characterized
by the front of the head forming a sort of clypeus surrounding the eye, and cover-
ing (in Chilocorus at least) the point of insertion of the antenne, which thus lie in
2, fovea beneath it. The inner edge of the epipleure of the elytra is also generally
divided behind the middle into two ridges, with a narrow channel between them
_ for the reception of the margin of the hind body, thus closing very effectually the
passage between it and the elytra. I do not find this character mentioned by authors,
but it exists in several of the genera I have at present studied. |
The species are distributed very widely over the whole world, Chilocorus alone being
_ CHILOCORUS. ee 65)
represented almost everywhere ; I have not, however, seen examples of it from further
south in America than Brazil. Exochomus has one representative in Europe, /. nigro-
maculatus, which is, perhaps, the most widely distributed of any species of the family,
being found from Northern Europe to the Cape of Good Hope, and from Siberia to
Australia, yet, strangely enough, it seems to have disappeared from England.
Crotch has included Platynaspis in the Chilocorides, and that genus agrees with the
rest of the subfamily in the structure of the clypeus, and on this ground I include
Corystes; but some other genera (as, for instance, the Eastern Cryptogonus) are much
more nearly related to the Hyperaspides, the presence of a seventh abdominal segment
in the male externally, depending very much upon its extrusion or otherwise, being no
doubt present, though possibly modified, in both subfamilies. Cryptogonus is indeed
treated by Weise as congeneric with Hyperaspis.

Chilocorus is a genus of about thirty-five species, distributed all over the world.
One species has lately been described from Australia, but Chzlocorus has hitherto been
considered to be represented by the allied genus Orcus in that continent. Two species
are found within our limits.

This insect has been long known to European entomologists, as well as the habit of
176 COCCINELLID.A.
its larva of feeding upon the cochineal insect (Coccus cacti). The larva has been
figured by Prof. Westwood in his ‘ Introduction to the Modern Classification of Insects,’
i. p. 392, fig. 49 (24).
Chilocorus cacti appears to be abundant in those districts where the particular species
of Cactaceze grow which are infested by the Coccus, or to which it has been introduced,
as in the case of Nopalea coccinellifera; but I have no direct evidence myself of the
distribution of the Chilocorus in South America.

to it.

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).
Head whitish yellow, narrowly black at the base; clypeus scarcely produced round
the eye, and the basal joint of the antenne visible from above; antenne and palpi
yellow. Prothorax black, the edge in front sometimes very narrowly whitish, but often
the black colour extends to the margin, the sides widely whitish yellow; the surface

visibly but very minutely and closely punctured. The elytra are together wider than
long, the shoulders produced (but not so much as they often are in Chilocorus); blood-
red, very obsoletely and finely punctured; the black scutellar mark is wanting in one
example, but in another the suture is very narrowly black; the apex is occupied by a
large squarish black patch, returning a little up the suture, and in the specimen with a
black suture a little farther along the margin. The legs are coral-red. The front tibic
are simple, grooved externally for the reception of the tarsi, which are nearly as long as
the tibie. |
Seven specimens were obtained, one of which is orange-red, but was obviously
captured when quite freshly emerged and soft.
This species has the form of Curinus, and might have been placed in that genus, but
for its wholly different colour, and that I do not consider there are structural differences
to separate it from Hrochomus.
4. Exochomus tricoloratus. (Tab. X. fig. 8.)
Transversim orbiculatus, niger ; capite albo, ore, pedibus abdomineque flavis, prothoracis lateribus late albido-
flavis, elytris crebre ac minute punctatis, macula subhumerali alteraque subapicali rotundata sanguineis.
Long. 4, lat. 43 millim.
Hab. Nicaragua, Chontales (Belt).
Head whitish yellow, the base black (but this part is generally hidden by the thorax),
the mouth and trophi yellow. Thorax black, with the sides white, this colour taking
the form of a round spot; in one example there is a triangular white spot in front.
Elytra black, each with a small but very bright red spot at the shoulder, but not on the
base, and another near the apex ; in one specimen there is a minute red dot near the
centre of each elytron. The elytra taken together are wider than the whole length of
the insect; epipleure red, so as to correspond with the spots.
We figure the example with two red dots on each elytron, and the thorax with a
white spot in front.
Two specimens.
5. Exochomus scapularis. (Tab. X. fig. 9.)
Nigro-subceruleus, subtus rufus; epistomate, labro prothoracisque margine laterali anguste rufis, elytrorum

base black in an indeterminate manner between the eyes. Thorax and elytra blue-
black, scarcely visibly punctate; the former with the lateral margins very narrowly
yellowish, the latter with a bright red spot at the front angles, and, in the two speci-
mens from Jalapa and Vera Cruz, with a small linear spot of the same colour, and very
indeterminate, just within the margin before the apex. |
The humeral spot varies a little in size and shape: in the specimen from Chontales
it is square, and a little more oblong than in any of the others, in which it is trans-
verse and placed just below the callus.
In all the specimens the front tibiz are angularly widened. The specimen from
Iguala has the elytra very slightly brownish, and with brown translucent margins,
being probably less matured. I think it possible that this insect should be associated
with Cladis nitidula, a species from Cuba and other West-Indian Islands. I do not,
however, regard Cladis as differing materially from Hxochomus.
One specimen from each locality are all that have been obtained. Our figure
represents the example from Jalapa.
6. Exochomus apicatus.
Orbicularis, nigro-cyaneus ; capite, corpore subtus, prothoracis limbo antico et laterali, elytroramque margine
reflexo, et apicibus, luteis ; elytris distincte subtiliter crebre punctatis. Long. 23 millim.
Hab. Panama, Bugaba, Volcan de Chiriqui 4000 to 6000 feet (Champion).
Head pale yellow, infuscate towards the base, in one example entirely black ; thorax
with the anterior margin only brown at the extreme edge, the sides narrowly margined
with yellow, but in certain examples (as the one with the head black) this is reduced
to a faint mark at the front angles; elytra blue-black, with the reflexed narrow margin
brown-red, widening at a third from the apex, but the yellow cclour narrowed again
at the sutural angle ; legs and body beneath yellow.
Six specimens of this insect were obtained, three of them near Bugaba. It is possible
that the darker-headed specimens are of one sex, but this is uncertain.

yellow, each elytron also with two yellow spots, the basal one of which is the larger.
The body beneath is pitchy with pale sutures, and the legs indeterminately pitchy, with
paler tibie and tarsi. Four examples.
Obs. This insect is labelled ‘“‘ Exochomus heirricht” in the Sallé collection, but I
have not found the description of such a species.
8. Exochomus sallzi.
Ater; elytris coccineis, singulis macula subapicali rotunda nigra. Long. 3 millim.
Hab. Mexico (Sallé).
Smooth and shining, the punctuation scarcely visible; the size and coloration
somewhat similar to that of Z. contristatus, Muls., but, besides the two spots of the
elytra, the body is black. The extreme limb of the elytra is, as usual, blackish. One
example.
9. Exochomus hogei. (Tab. X. fig. 11.)
Ater, nitidus ; elytris coccineis, singulis punctis duobus parvulis discoidalibus, et uno communi apicali suturaque
in medio, nigris. Long. 4 millim.
Hab. Mexico, Villa Lerdo in Durango (Hoge).
Smooth, shining, and with the elytra very convex for this genus. The margins are
scarcely, if at all, expanded, the limb very narrowly black. Of the elytral spots that
nearest the base is, in our single specimen, the smaller of the two, and is placed on
the scarcely perceptible callus; the second is placed a little behind the middle; the
apical spot is similar to that of the East-Indian £. uropygialis. The body and legs
are black, only the tarsi are reddish. One example.
PENTILIA. |

Bluish black above, the thorax and base of the elytra brassy ; ; head, legs, and
abdomen, and the sides of the thorax nearly as far as the hind angles, and also the
front margin, very narrowly, yellow. Elytra very convex, and viewed laterally rather
gibbous, the humeral callus distinct, very finely but thickly and distinctly punctured.
The tibie are compressed on the outer side, and a little expanded towards their base.
This insect, of which we have only obtained a single male example, is twice as large
as Pentilia egena, and is more convex than that species; the base of the thorax is also
less V-shaped, the bases of the elytra being less inclined. 1 cannot at present associate
any specimens from Bugaba with P. convexa as females, the only example of that sex
from that locality being apparently referable to P. egena, the male of which, in addition
to the differences pointed out above, has the front angles of the thorax broadly yellow
and more rounded.

a little expanded. .
We have received only one specimen of each of the supposed sexes; they were both
met with at the same time and place, and, though differing in colour, I have little
doubt they are correctly associated as one species.

Chapuis, following Crotch, has united these genera. I have not seen a true neis ;
the three species from Ceylon referred to it are probably not congeneric. Exclusive of
these, about fifteen species of Cryptognatha have been described; the area of its
distribution appears to be from the Southern States of North America to Brazil.

The example figured is from Chontales.
Subfam. HY PERASPIDES.
The Hyperaspides are, as Chapuis remarks, chiefly distinguished by the epipleure of
the elytra being furnished with fossee, which are usually deep, and which permit the
knees of the middle and hind legs to move over them with facility. In addition to
this character, we here meet with another, possessed by very few Coccinellide, viz. the
presence of a tooth on the front tibie.
The subfamily as here restricted, by the exclusion of Corystes, Pentilia, and Crypto-
gnatha (the two latter of which were included in the Hyperaspides by Chapuis),
contains but few genera, yet the species are numerous, those of the genus Hyperaspis
alone amounting to about two hundred. By far the larger number of these are from
the New World, several, however (including the type of Hyperaspis), are European,
_ and a few have been described from Africa.

Brachyacantha consists of a little group of species which, with two exceptions, are
peculiar to the northern continent of America, and are remarkable for their strong
resemblance in form, as well as in structure, to some genera of Phytophaga, especially,
perhaps, to those of the Cryptocephaline, such as Monachus and Scolochrus. The
genus is not well separated from Hyperaspis, both Crotch and Chapuis referring to the
arming of the front tibie with a spine as a permanent distinction. Good sexual
characters, however, exist in several species of Brachyacantha on the underside of the
ventral segments. No author, excepting Crotch for one species (B. dentipes), appears
to have noticed these. About twenty species have been described ; but from the undue
importance given by Mulsant and others to the markings alone, it is clear that several
of these can only be regarded as varieties. The males of the species of the whole sub-
family may generally be recognized by their yellow heads, and the paler colouring of
their legs and other parts; but the structural characters above alluded to, and the
presence of an additional segment (the seventh ventral one), should always be noticed.
The absence of a basal marginal line to the thorax is, I think, quite illusory, for
BRACHYACANTHA. 185
this line, merely indicating the finely impressed margin, cannot be seen in many cases
when the thorax is not detached from the base of the elytra. And this is the view
Chapuis has taken of the value of this character, which Mulsant has used with some
insistance.

B. lepida is very variable as regards size (the larger examples being 4 millim. long,
while some occur of scarcely half that size) and colour, and also in the degree to which
the markings become confluent.
Of the var. a, the colour of which may be due to immaturity, Mr. H. H. Smith met with
a very large number at Teapa in Tabasco; and these appear to be all of the typical
form, 7. ¢@. the spots are detached. Varieties with the two discoidal spots just united by
a line occurred, in company with typical forms, at the city and elsewhere in Guatemala.
In the variety which I designate 6 the discoidal spots are united together and to the
central spots, as well as to the subapical spot, leaving six triangular yellow spots on
each elytron—one on the base near the scutellum, with two others following almost in
a line, and the yellow margin is dilated into three spots corresponding to these. Of
this variety numerous specimens were met with at Tapachula. I have not observed
any structural character in the abdomen of this insect.

An inspection of the type of B. bipartita in the Crotch collection leaves no doubt in
my mind that the above names apply to the sexes of the same species. It is apparently
not common.

Hab. Mexico, Parada (Sallé).
Two specimens of this species are before me, agreeing very closely ; they are clearly
allied to B. westwoodi, but are larger than that species (with the exception of one
specimen from Yolos, of which the determination is a little doubtful), and differ,
moreover, in the large yellow mark on the anterior angles of the thorax. This mark
occupies the whole angle, and extends along the side almost to the base; it is
prolonged obliquely into the disc, leaving the front margin black. ‘The body beneath
is black, the tibie and tarsi yellow.
This insect was labelled Brachyacantha aymardi in the Sallé collection.

Entirely black, with the exception of the elytra, which are of a rich blood-red colour,
with the suture (narrowly at the base, more widely at the apex), and three small spots
on each, black.
This fine species cannot be confounded with B. aymardi, as it is larger, the head and
thorax are wholly black, and the elytral markings are different.
The single specimen obtained by Hége is the only one I have seen. It is apparently
a female. |

The male of this species, besides having the head and legs entirely yellow, has the
third ventral segment with the hind margin raised into two tubercles in the middle,
the fourth, fifth, and sixth segments each with a semicircular impression forming a sort
of fovea.
I find great difficulty in determining whether certain specimens from various localities
in Mexico and Guatemala are to be referred to this species or to B. erythrocephala.
When the two anterior spots on the elytra of the latter are united, the colour-
distinction is lost, and the more oblong form of this species passes insensibly into
that of B. erythrocephala. I have joined B. erythrura, Muls., with B. dentipes, as
beyond colour there is really no difference; it seems to be a rather scarce variety
in which the anterior fascia is obliterated, and intermediate forms occurred with it
at Atoyac. For the same reason B. subfasciata is now sunk in a synonym.

thorax are yellow, the base of the latter black for rather more than half its length in

it is allied to B. pygidialis, but is a shorter and rounder insect. B. conjuncta varies
considerably in size, from about 24-5 millim.in length. In one large female from Etla
the head and thorax are black, only a small dot on the former and the tips of the front
angles of the latter being red, and the underside and legs are black in this specimen ;
while in a smaller male, from Yolotepec, the head, the greater part of the thorax, and
the legs are yellow.

After the inspection of a large number of specimens, and of the types in Crotch’s
collection, there is no other course open to me than to unite the various names quoted
above under one species, while I cannot concur in regarding them as synonymic with
B. ursina—the latter being a more oblong insect.
The females of B. decempustulata have but four yellow spots on each elytron,
while in the males there is a small yellow spot on the humeral angle as well; the
males have also the abdomen impressed in the middle from the second segment to
the fifth.
From Hyperaspis jucunda and H. jocosa, Muls. (which are similarly marked), the
generic character of a sharp tooth on the exterior edge of the anterior tibie will at once
separate it; but it will be observed that the shoulder-spot is always more prolonged
down the side in the males of H. jocosa, and that the three large apical spots are more
closely packed, the lateral one in the middle being always a little nearer the apex in
H. jucunda.
B. decempustulata varies very much in size. The punctuation, as Leconte has
remarked, is deeper and more distinct than in B. wrsina.
B. bollii, Crotch, appears to me to be nothing but a colour-variety of this insect, and
occurs with it at Dailas in Texas.
Obs. Three exponents of Hyperaspis billoti, Muls., in Crotch’s collection, labelled
‘¢ Philad.,” and which are Brachyacanthe, belong to this species ; but they may probably
be wrongly identified with Mulsant’s insect, which is South American.

B. albifrons (Say) with this species; but this view is not borne out by his collection,
and it seems to have been arrived at rather hastily on the exponents of those species
in Leconte’s collection. Judging from the specimens of B. decempustulata in Crotch’s
collection and my own, and also from those from Mexico, I think the insect is distinct
from small examples of B. ursina with very small spots, which may be recognized by
their more oblong form, more narrowed in front.

At first sight resembling B. lepida, but to be immediately distinguished from it or
from any other Brachyacantha known to me by the marking of the prothorax, which is
like a broad-arrow gy, with the barbs lying on the V-shaped base. The suture has not
a distinct spot (as it has in B. lepida), but is more widely pitchy-black immediately
below the scutellum than at the apex. The legs are entirely pale testaceous.
The male character of an impressed fossa along the middle of the abdomen is very
distinct, but its sides are apparently not tubercular. .

Hab. Mexico, Teapa in Tabasco (H. H. Smith); Costa Rica, Caché (Rogers); Panama,
Volcan de Chiriqui, Bugaba (Champion).
This species is one of a series which, with some Hyperaspides, have the elytra
marked almost exactly alike, viz. with five yellow spots on each, as in B. decempustulata.
B. fenestrata may, however, be easily recognized by the thorax having two pale oval
spots near the middle of the base, almost but not quite touching it. Of the two
discoidal elytral spots, the posterior one seems always to be a little smaller than the
basal one; of the three marginal ones, the humeral spot is small, occupying the angle,
the middle one is just between the two discoidal spots, and the apical one is more
oblong than in most of its allies. These markings are also very pale yellow, almost
white in some male examples.
The fossa on the abdomen of the males is very distinct, and the middle of the
metasternum is also impressed ; the margins of the segments are raised in the middle
and at the sides of the fossa almost tuberculate. This structure is common to the
Brachyacanthe that have the abdomen impressed, but seems to vary in degree.
The female has the head yellow, but the front of the thorax is pitchy-black.
A very extensive series of specimens were obtained by Mr. Champion, but I have
only seen one from Costa Rica.
The specimens from Teapa diverge a little from the type in having the dark mark
on the thorax divided by a wedge-shaped spot in front, so as to resemble the letter M
more than in the Panama specimens.

Hyperaspis differs from Brachyacantha in having the front tibie unarmed; in some
species the front tibie are angularly widened, but they cannot be termed “ denticulate.”
The abdomen in the male is impressed and fossulate in some species, while in others it
_ appears not to be so.
A very large number of species must be referred to the genus—the typical species
(H. reppensis) and a few others are European, a few are Asiatic or African, but by far
the larger number of those described are from America, where the genus has an ex-
tensive range, from Lake Superior to Brazil. About 168 species have been described.
I have seen no species from the far East or from Australia which can properly be
referred to this genus, but in Africa it appears to be distributed over the whole
continent. The species are generally of small size.

This insect exactly resembles certain varieties of Brachyacantha decempustulata, so
much so that but for the absence of the spine of the front tibiz I cannot distinguish
the females. The males have no fossa on the abdomen, and the shoulder-spot of the
elytra is a little more prolonged down the margin, so as sometimes to unite with the
middle marginal spot.
Iam unable to determine with certainty whether this species is the C. jocosa of
Mulsant’s description or not, for the following reasons:—It appears that there are
several species so closely allied that the females are hardly separable. We have not
received a specimen of the species here described from Mexico, nor have we seen the
type of #. jocosa from Chevrolat’s collection. A single specimen labelled “St. Paul” is
in Crotch’s collection, and this appears to belong to the same species as ours, excepting
that it has a nearly black head.
I do not think that H. bis-quatuorpustulata differs specifically from it. The type is
now before me; it agrees with our female specimens in all respects, except the most
trivial form of the apical spot.
To identify these most closely allied species from female types alone, from such
distant places, seems hardly possible.

This belongs to a little group of species which have five yellow spots on each elytron
—two on the base, two in the middle transversely, and one apical. These species are
so exceedingly like Brachyacanthe, such as B. decempustulata, that they can only be
known by the structure of the front tibie and of the abdomen in the male. Iam unable
to identify an insect taken by Mr. Champion on the Volcan de Chiriqui with Z. levratz,
because the female of it has only four elytral spots, the shoulder-spot being absent;
while H. levrati, female, the only sex known to Mulsant from Mexico, is described
as having five spots. The solitary example representing H. levratt in Crotch’s collection
is a male; but it is from Brazil, and is apparently from Reiche’s collection. Mulsant
did indeed describe an insect from Brazil as the male of Cleothera levrati [Opusc. Ent.
p. 89 (1853)]; but how he identified it with the Mexican female I do not know.
The Chiriqui insect is nearer still to H. gacognii, Muls., another Brazilian insect,
according to Crotch’s typical example ; but I hesitate to refer it to that species without
seeing female examples.

In this species the thorax has the sides widely yellow, and the central black vitta

united with the central black portion. The elytra have each six yellow marks—one
near the scutellum, one on the shoulder, rather linear, a pair transversely placed, almost
united and transverse themselves, in the middle, and a pair near the apex, often united.
In the female the central thoracic line is not wider in front, where, indeed, it scarcely
divides the black portion ; the head is black, with a yellow spot, and the whole insect
is more suffused.

the middle at the base. Elytra with the shoulder and a pair of spots placed a little
before the middle, the marginal one of which is joined with the shoulder-stripe, yellow ;
there is also a pair of subapical spots, joined together, and also with the yellow apex
along the margin; these spots are sometimes suffused, so as to form a heart-shaped
yellow apical patch enclosing an angular black marking.

This insect so closely resembles Brachyacantha decempustulata that it is difficult to
separate the two species unless the generic characters are observed; nevertheless, most
specimens of H. billoti are very much smaller than any of the allied forms. The males
have the shoulder-spot clearly defined, and it seems to be present sometimes in the
female, though obscure and very much reduced in size, being, in fact, a mere point.
A very large, and on the whole uniform, series of specimens were taken by Mr. H. H.
Smith at Teapa; some of these scarcely exceed one millimetre in length.

This insect does not accord with H. elegans, Muls. (which is sunk by Crotch as syno-

nymous with H. undulata), if a specimen in the Sallé collection is correctly so named,
and which certainly agrees with Mulsant’s description. Neither species is represented
in Crotch’s collection, and it is certainly better to keep them distinct. The present
species, of which we have received a series from Morrison under the name H. undulata,
agrees with Crotch’s description, and no doubt occurs in the adjoining State of California.
The other localities quoted by Crotch? may refer to H. elegans.

A single example of a Hyperaspis collected by Mr. Champion on the Volcan de

now before me. It differs mainly in the coloration of the thorax, which in the type of
HH, bicruciata (a male) is yellow, with the middle and base rather narrowly infuscate,
the head being yellow. In our example (a female) the head and middle of the thorax
are black. There is, however, nothing in this inconsistent with the supposition that
they represent one species.

Crotch appears to have known this species, but it is not represented in the Cambridge
collection. There are, however, in our collection several specimens which agree very
well with the description, and which I accordingly refer to it, besides some others sent
by Morrison. Fabricius! gives as locality “ America meridionalis,” and our insect has
certainly a wide range in Central America. The specimens from Sonora differ from
the others in having the lateral spot on the elytra elongate, reaching almost to the
apical one. H. sexverrucata is not included by Crotch among the Hyperaspides of
the United States.

The single example in Crotch’s collection is labelled “‘ type,” but there is no locality-
ticket upon it now. This agrees with our specimens, and is a male, and as Reiche’s
types of this family were acquired by Crotch it is probably the true type.
The female, of which we have examples from Jalapa, Cordova, and Oaxaca, as well
as one from Calderas in Guatemula, have the head black.
The various examples differ greatly in size, some being nearly three millim. long, while
others from Belize, Zapote, and Chacoj are scarcely more than one millim. long; and
they also vary in shape, some small specimens appearing to be shorter than others.

The body and legs are black. The elytra have the large red patch extending to the
margin, just leaving the reflexed edge black; the suture and base are rather widely, and
about a quarter of the elytra at the apex, black; there isa spot on the callus, not free,
but united with the black of the base.
This is an embarrassing insect to deal with, as a single female specimen only has
been received. It is probable, however, that it belongs to a species distinct from any
that has yet been described.

the base is black and it is flattened on the basal side; the posterior spot is much
larger, round, equally distant from suture and margin, and (in the male example) a
little emarginate on the apical side.

Hab. Mexico, Guanajuato (Sallé), Cuernavaca in Morelos (Hége).
I am unable to follow Crotch in connecting this species with H. undulata (Say). It
is a smaller, more oval insect, with the border of the elytra neatly yellow from the
humeral angle to the apex; the pale margin is sinuate on its inner side, almost termi-
nating at the sutural angle, where it is widened just before the angle, thus representing
the apical spot ; and there is one discoidal spot.
fH. elegans is evidently a different species to the one I have recorded here as H. undu-
lata, and it agrees well with Mulsant’s description 1. ~The single example in the Sallé
collection is a male, with the head yellow; it was named JH. elegans in his collection.
H. elegans has not therefore, so far as I am aware, been found in the United States.
I observe that the lateral margin of the thorax in the single male specimen of
H. elegans before me is much narrower than in H. undulata, and that the front margin
is not yellow.

This insect is very closely allied to the species here recorded as H. elegans, principally
differing from it, in the males, in the absence of a discoidal spot, and in the yellow
border of the elytra being distinctly terminated before the sutural angle. The thorax
in the male of H. fimbriolata is also very narrowly yellow in front, this not being the
case in the single male of H. elegans that I have been able to examine.

The head is yellow. The thorax is of the same colour (a rich orange-yellow), with
the exception that in some specimens the base in the middle and the outline of a
roughly-shaped M-like mark are indicated,and in these the scutellum is also dark.
The disc of the elytra is black, with a ramus extending to the callus, and a sécond

projection on each side about one-third from the apex, the black being also prolonged
down the suture almost to the apex; thus there is an irregular but wide orange margin.
The punctuation is exceedingly fine.

were obtained.

Hab. GuatEMata, Capetillo, Zapote ( Champion).
A little larger and more convex than H. calderana, and with the punctuation more
distinct than in that species. The thorax has the centre black, narrowing in front, and
the front margin very narrowly yellow, the black disc being less indented by the yellow
margin along the sides. In one example from Capetillo there is, in addition, a lunulate
yellow spot on the base just joined with the margin. In a second example from the
same locality there is a minute yellow dot near the scutellum, while the single specimen
from Zapote has the base of the elytra wholly black. Judging from the exposed pygidium,
the Zapote specimen is a female ; it has the abdomen in great part bright yellow.
H. guatemalensis is very nearly allied to H. calderana, but will, I think, prove to be
distinct.
ix. Llytra black, with the apex white.

thorax in marking.

The ground-colour above is bright yellow. The thorax is deflexed at the sides,
strongly transverse, and with the base rounded, as in all the very convex species ; with
four irregular and ill-defined spots—one in the middle of the disc, often partly divided,
a small one before the scutellum, sometimes only indicated on the margin, and one
on each side on the base. ‘The elytra have each two spots near the suture, the anterior
one of which is oblong or hamate, and the posterior one is very near to its fellow on
the other elytron, and four exterior to these—three submarginal, one discoidal.
This species is somewhat like the Brazilian H. triacantha, Muls. A specimen from
Teleman is figured.

Very variable in size, and more uniformly coloured than H. subsignata. The head
and thorax are usually whitish-yellow, the latter having occasionally some indistinct
fuscous markings; in specimens from Caldera these take the form of five spots—two
discoidal arcuate ones with an antescutellar spot form a sort of Y, the stem of which is
sometimes wanting, and in these examples there are two basal spots. The elytra have
usually a series of brown punctures near the suture, and indications of similar obsolete
punctures near the callus and along the margin. The anterior tibie are compressed,
and slightly widened on the exterior side in the middle.
A great many examples were met with by Mr. Champion.

it is obscure piceous, with a brownish-yellow spot. The thorax in the male has a black
stripe along the base, which is produced into two horns in the middle; while the
female has the disc more widely black, with a narrow division, not reaching the base.
The suture is not darkened at the scutellum, but below it, and is bordered with darker
brown than the rest of the elytra; in some examples it has a very obscure, transverse,
subapical cloud. |

along the suture, and one or two series near the margin are fuscous; they have the
tips black for about a quarter of their length, forming a common transverse spot at
the apex; the general colour is orange-yellow. The punctuation of the head and
thorax is very fine, scarcely visible in the male; that of the elytra is rather stronger,
but still very fine and close. The body beneath is yellow; but in the female it is
often infuscate in the middle. The three specimens from Zapote, all females, are more
orbicular than the type, and they have the thorax wholly black (or nearly so), while
the apical spot is small; but I do not believe that they represent more than a variation
of the same species.
Numerous specimens, including both sexes, were met with on the Volcan de Chiriqui,
at elevations of from 2500 to 4000 feet. Amongst the few received from Bugaba,
one, a female, pretty closely resembles the Zapote specimens, and has the apical spot
almost obsolete.

HYPERASPIDIUS.
Hyperaspidius, Crotch, Trans. Am. Ent. Soc. iv. p. 382 (1873).
The species which forms the type of this genus is referred to the Linnean Chrysomela
trimaculata; it was separated from Hyperaspis by Crotch, on the ground that the
epipleure of the elytra are not foveolate. Chapuis in the ‘Genera des Coléoptéres’
does not notice the genus. Three species are referred to it by Crotch.

This is a depressed, rather oblong species; the head and sides of the prothorax are
yellow; the elytra have the basal and lateral margins yellow, the latter joined to a
vitta, which runs parallel to the black suture, at the apex. In the specimen from
Chilpancingo, which I think is a female variety of this species, the head is black,
the thorax only narrowly margined at the sides, and the subsutural vitta is joined to
the yellow margin at the base and is interrupted at the apex; it is also smaller than
the typical examples.
Obs.—I have very carefully examined one of the specimens from Guanajuato, and
also a specimen from Crotch’s collection labelled “ Chevr. ex Muls.” Neither of these
bears out Mr. Crotch’s statement that the epipleure are “not foveolate”; in fact,
the fovee are perfectly apparent, and those for the hind knees are marked as usual by
a sinuation of the margin, which can be seen without turning up the insect. Both
our specimens from Guanajuato are males: the yellow vitta in one of these is joined to
the margin at both ends, and in this respect is perfectly similar to Crotch’s specimens ;
the one I have examined is a female.
Subfam. DISCOTOMIDES.
The Discotomides are a group of five or six genera peculiar to the New World, of a
highly developed form, containing very glabrous species of great beauty, of the average
size or above it, and often distinguished by having one or two joints of the antenne
coalescing so as to give them the appearance of being from eight to ten in number.
Their position is doubtful, but they certainly do not come in well where Crotch
placed them, following Lithophilus. Chapuis places them as his third Group between
the “ Coccinellites” and the “ Cariites.”
We here place them as conveniently closing the smooth section.
They form a very natural link with the Endomychide through Endomychus, and
seem worthy of a higher rank than can be given them in a linear arrangement.

Seladia is a genus which of all the Coccinellide exhibits the greatest divergence
from the normal type, and very closely recalls the Endomychidous form in some of its
characters. The antenne are robust and have the club absolutely as in some genera
of that family, while the tarsi, no less by their clearly tetramerous structure, might
almost cause these insects to be attributed to the same family. The colour and
markings and the depressed form are suggestive of either the Endomychide or the
SELADIA. 205
Erotylida. And the same remark applies to the South-American genus Micaria,
which at present has not been found in Central America.
Mulsant has described several species, but, according to Crotch, five of these are but
varieties of one. They are insects of great beauty and variety, and above the average size.
1. Seladia nigricollis.

Hab. Mexico }~4, Jalapa (Hoge), Toxpam, Cordova (Sal/é).
A considerable series of specimens were obtained by Hége. The variety S. visceralis
appears to differ only by having the abdomen red; none, however, of the examples
sent by Hoge are of this form.
2. Seladia augustiniana.
Seladia augustiniana, Muls. Monogr. Coccin. p. 155°; Crotch, Rev. Coccin. p. 304%.
Hab. Mexico ! ? (Sallé), Jalapa (Hoge).
3. Seladia beltiana. (Tab. XI. fig. 14.)
Rufo-testacea; antennis, palpis, geniculis, tibiis tarsisque nigris ; elytris albido-flavis, maculis duabus magnis,
limbo laterali et sutura tenuiter (hac ad apicem in macula dilatata) nigris. Long. 7°5 millim,
Hab. Nicaracua, Chontales (Belt).
Head and thorax reddish ochreous, the sides of the latter whitish, a little refiexed, and
subdiaphanous. The scutellum, the body, and femora are ochreous; the tibie, tarsi, and
‘knees are black. The elytra are of a very pale yellow, each with the extreme edge and
suture black; the sutural marking expands suddenly at the apex, forming a pear-shaped
spot, and on each elytron is a large black spot near the base, equally distant from the
base and margin and suture, and of which the apical side is nearly straight ; and another
somewhat transverse spot near the apex, of which the inner edge is straight, thus leaving
a distinct yellow cross on the elytra taken together. The whole upper surface is very
smooth and shining, nor are distinct punctures visible anywhere. The abdomen is
rather paler, especially towards the apex, than the rest of the body. This species is
allied to S. augustiniana, but the colour of the body is different.
Two specimens obtained by the late Mr. Belt, one of which we figure, are all I
have seen. .
4. Seladia alboguttata. (Tab. XI. figg. 15; 16, var.)
Sanguineo-rufa; antennis, palpis, tibiis, tarsis, prothoracis maculis duabus in margine antico, et duabus alteris
basalibus, his sepe conjunctis, nigris ; elytris nigris, singulis maculis duabus basalibus, tribus fasciam
medianam prebentibus, et una subapicali obliqua, albis. Long. 5-7 millim.

Var. @. Elytris albis nigro-limbatis, maculis duabus magnis sepe conjunctis apiceque nigris. (Fig. 16.)
206 COCCINELLIDZ.
Hab. Guaremata, Capetillo (Champion).
Rather smaller on the average than any of the preceding species; the head and
thorax of a beautiful blood-red colour, the latter with a black central marking, which
is very variable, consisting of either two spots on the front margin, and two large ones
usually united on the base, or these may all be united forming a broad central vitta
with a central linear red spot, and even with the hind angles black. The elytra are
black and shining, with two white spots on the base, but not quite touching it nor the
suture (the external limb of the elytra being always black), one subscutellar and the
other subhumeral ; three spots form a slightly arcuate fascia about the middle, and
there is an oblique spot (formed of two united, occasionally divided) near the apex.
The whole body beneath, with the legs up to the knees, is of a clear blood-red colour.
The antenne are black, with the first three or four joints reddish beneath; the palpi
are pitchy, paler at their bases; the tibize and tarsi are black.
The variety « is similarly coloured, but the spots on the elytra have become
brownish-red, but I think only from discoloration since death.
The variety B results from the more or less complete fusion of the white spots on
the elytra. Only two specimens of this variety were obtained, and they differ slightly
in the degree to which the white colour has extended: in one of them the anterior
large black spots unite at the suture, but are separated from the margin; while in the
other they are just interrupted at the suture, but are united with the posterior black
spots by two narrow lines, indicating the position of the middle white spot of the fascia
in the type. |
Numerous specimens of this beautiful species were taken at Capetillo by Mr. Cham-
pion, including the two of the variety 8 above described ; they were all found estivating
under bark, on the slope of the Volcan de Fuego.
We figure a specimen of the type, fig. 15, and one of the variety , fig. 16.
Subfam. PORIIDES.
With the Poriides we commence the section of the Coccinellide which have the
entire surface more or less pubescent. While the classification of the family by this
character presents considerable difficulty, there is nevertheless a true affinity between
many of the hairy genera and their subdivision into subfamilies, and their relative
position both with regard to each other and to the foregoing divisions is to be regarded
as, at present, an unresolved problem. Crotch placed Porta at the head of his Rhizo-
biides, but the genus diverges in its eyes not being coarsely facetted, and I prefer to
regard them, with Mulsant and Chapuis, as forming a separate group peculiar to
America. |
PORIA. 207
PORIA.
Poria, Mulsant, Spec. Col. Trim. sécur. p. 885 (1850); Crotch, Rev. Coccin. p. 288; Chapuis,
Gen. Col. xii. p. 204.
Poria is an assemblage of species of two types of colour—blue or green or blackish
insects ; and red species agreeing in having an irregular stellate punctuation, and long
rather well-developed antenne. They would appear to be more numerous in South
America than in our region.
1. Poria salle#i. (Tab. XI. fig. 18.)
Poria sallei, Crotch, Rev. Coccin. p. 289".
Nigra, supra cyanea; ore, epistomate, antennis, palpis, pedibus abdomineque saturate rufis; supra breviter,
densius griseo-pubescens ; capitis vertice cyaneo, prothoracis margine antico et laterali tenuiter rufis ;
elytris fortiter, irregulariter, subconfluenter punctatis. Long. 7-9 millim.
Hab. Mexico}, Juquila (Sallé), Cordova (Hoge); Guatemaua (Sallé), Coban, Panima,
Purula, and Cubilguitz in Vera Paz, Duefias, Zapote (Champion).
An example from Purula is figured. This insect very closely resembles P. cyanea, a
Brazilian species; indeed it scarcely differs from it except in having the metasternum
black.
The examples (two in number) from Zapote are rather more greenish in tint than
the others. Mr. Champion collected a large number at Purula.
2. Poria chiriquensis, (Tab. XI. fig. 19.)
Porie sallwi similis et valde affinis, prothoracis lateribus late rufis modo differt.
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).
Three examples of this insect were obtained in Chiriqui by Mr. Champion, and it
seems as much entitled to rank as a species as P. sallei. The thorax has a black vitta
in the middle, of about equal width with the yellow sides. All the species of Poria
are very closely allied in form, punctuation, and general details. ‘The size of the three
examples is that of full-sized P. sallai.
3. Poria cuprea. (Tab. XI. fig. 20.)
Statura et forma P. sallei similis et iterum affinis, supra cuprea pube brevi aurea dense vestita; subtus
(abdomine rufo) nigra; capite antice, ore, antennis, palpis, prothoracis marginibus tenuiter pedibusque rufis.
Long. 8-9 millim. .
Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion).
In form and punctuation, and by the black breast and black epipleure, P. cuprea
is more closely allied to P. sall@i than to P. cyanea. It is rather smaller on the
average than those species, and of a brilliant brassy copper colour above. The
pubescence on the head and thorax is especially dense, and is golden yellow
208 ~ COCCINELLIDA.
instead of grey ; in fresh examples it is equally dense on the elytra, but usually appears.
to be worn off. A series of about twenty examples was obtained by Mr. Champion,
some below, but the greater part above, 4000 feet.
4. Poria rubicunda.
Oblongo-ovata, rufa, pube brevi grisea tenuiter vestita ; elytris fortiter crebre irregulariter punctatis. Long.
7-9 millim.
Hab. Panama, Volcan de Chiriqui 3000 feet, Bugaba (Champion). .
Entirely deep rusty-red, sometimes the thorax has an indistinct cloudy marking near
its centre, and in a few examples the middle of the metasternum is dark. The head
and thorax are hardly visibly punctate, but the elytra are almost rugose, the larger
punctures being numerous and confluent. P. rubicunda is very nearly allied to
P. batesi, a Brazilian species described by Crotch, the type of which is now before me ;
but the punctuation of the elytra is coarser, and other small differences in colour incline
me to think it is probably distinct. There is, however, no other specimen of P. batesi
than the type in Crotch’s collection, and it is not in very good preservation.
A series of examples was collected at Bugaba, but only a single specimen from the
Volcan de Chiriqui. |
5. Poria sanguinitarsis.
Poria sanguinitarsis, Muls. Spec. Col. Trim. sécur. p. 885° ; Crotch, Rev. Coccin. p. 289°.
Hab. Nicaragua, Chontales (Belt).—Sourn America, Colombia 2, Brazil ! 2.
A single example, received from the late Mr. Belt.
6. Poria marginithorax.
Prodilis marginithorax, Crotch, Rev. Coccin. p. 276°.
Hab. Mexico! (Sallé, ex coll. Sturm), Orizaba (Sallé), Amula and Chilpancingo in
Guerrero (H. H. Smith), Jalapa (Hége).
Crotch, in describing this insect, associated it with Prodilis pallidifrons, a South-
American species. I have examined the type of the latter, and find that P. marginithorax
differs in many essential particulars from it. The punctuation of P. pallidifrons is.
uniform, though deep and sparse, and the thorax in our insect is not margined. It, in
fact, agrees with the smaller species of Poria, which have shorter antenne than the
typical forms. The punctuation of P. marginithorax is strong and close; the larger
punctures are stellate, often confluent, and the whole surface is crowded with the
smaller punctures. ‘Iwo specimens obtained by Sallé at Orizaba have an irregular,
ring-like marking common to the two elytra, and have also the head red, and the thorax.
red with only a dark mark on the base. These may probably represent the male.
PORIA.—EUPALEA. 909
7. Poria sanguinolenta.
Sanguinea ; capite, prothoracis disco elytrisque nigris, his subenescentibus. Long. 6 millim.
Hab. Panama, Bugaba (Champion). —
Head black, with a faint greenish tinge; antenne rather short for this genus, clear
coral- or blood-red ; front of the head, palpi, and the bay of the eye (the cut out portion)
red. ‘Thorax with the base not very deeply sinuate, scarcely punctured, the sides blood-
red for nearly one third of the width. Elytra rather obsoletely punctate; in the
specimen before me, which appears to be worn, very little pubescence is to be seen and
only at the sides and apex, where it is very short and of a grey colour. The legs and
body are clear blood-red.
This is not very like any species of Poria that I have seen. There is unfortunately
only a single specimen.
8. Poria detrita. (Tab. XI. fig. 21.)
Nigra, subcwrulescens ; capitis fronte, antennis, palpis, pedibus anticis et posticis (basi excepta), intermediis
femoribus pretermissis, abdomineque fulvis ; supra griseo-pubescens, prothoracis disco elytrisque singulis
macula magna quasi denudata nigro pubescente. Long. 5 millim.
Hab. Panama, Volcan de Chiriqui (Champion).
Above blue-black; thorax very finely punctate and shining, the head a little more
distinctly so; the labrum, and in the male the front of the head also, yellow, the base
bluish-black ; antenne not reaching the hind angles of the thorax, the three terminal
joints forming about a third of the length, serrate within. ‘Thorax short, as wide at
the base as the elytra, but narrower in front, the base margined by a very fine line, the
width more than twice the length ; elytra nearly hemispherical, but gibbous, the black
shining patches very distinct and clothed with black pubescence, the rest of the elytra
and thorax densely pubescent and hoary. Abdomen and legs yellow, the coxe and
bases of the femora of the front and hind legs, and the middle pair as far as the knees,
black. In the male the sixth segment of the abdomen is visible and is notched.
Poria detrita bears a very deceptive resemblance to a large Azya, as well as to
Ladoria. The puncturing of the elytra—which is (as in other Pori@) ‘* unequal,”’@. e. con-
sisting of larger and smaller confluent punctures,—the longer antenne, with a lax and
serrate club, and the simple tibiz (not grooved externally except for a short distance at
their bases) must be examined in order to separate it from insects of the allied genera.
Three examples.
EUPALEA.
Eupalea, Mulsant, Spec. Col. Trim. sécur. p. 889 (1850) ; Crotch, Rev. Coccin. p. 290; Chapuis,

210 COCCINELLID.
Eupalea and Oryssomus. I regard the genus here as much more nearly allied to the
latter than to Poria. |
Nine species of Ewpalea have been described; of these two or three are allied rather
nearly to EZ. picta, the only species that has yet occurred in Central America; the rest
by their markings resemble certain Psyllobore, which have a reticulate pattern ; all are
peculiar to North or South America. Recently Mr. Blackburn has rather doubtfully
referred an Australian insect to the genus; but it is probable that the’ position cannot
be maintained. The claws in Eupalea are very distinctly bifid, and the thorax is
margined at the base by a fine line. The antenne are rather long and have a laxly
formed three-jointed club.

Var. elytrorum maculis parum distinctis.
Hab. GuatemaLa, San Gerénimo (Champion).
A single specimen captured at San Gerdnimo by Mr. Champion is almost unicolorous,
but this is probably only due to immaturity. The insect seems to be pretty common
at Jalapa, an example from which locality is figured.
ORYSSOMUS.
Oryssomus (Reiche), Mulsant, Spec. Col. Trim. sécur. p. 939 (1850) ; Crotch, Rev. Coccin. p. 292;
Chapuis, Gen. Col. xii. p. 218.
Oryssomus was proposed by Reiche for the species which occurs in our region as well
as in South America, where it was first detected. The thorax completely covers the
head and is translucent in front. The head has the eyes coarsely facetted, not cut out
as in Eupalea; the antenne are short, their basal joint large and hatchet-shaped, the
last four or five forming a large connate hatchet-club. ,
The genus thus differs in many important aspects from Hupalea, but nevertheless by
the form of the thorax, and by the depressed oblong body and elytra, 1s clearly allied
to it and was properly placed immediately following it by Crotch. Six species were
added by him, five of which are Chilian and one Brazilian.
1. Oryssomus subterminatus, (Tab. XI. figg. 23; 23a, antenna.)
Oryssomus subterminatus (Reiche), Muls. Spec. Col. Trim. sécur. p. 9391; Crotch, Rev. Coccin.

AMERICA, Colombia !, Venezuela 2.
This remarkable species has evidently a very extensive range ; Reiche’s specimens,
from which Mulsant described the species, are now in the Cambridge collection, and
one of these is labelled “Cuma . ..,” the remainder of the word having apparently been
cut off—Cumana being no doubt the locality, many of Reiche’s insects having come
from there.
The example figured is from Bugaba.
Subfam. EXOPLECTRIDES.
The Exoplectrides combine many of the characters of the foregoing subfamilies; and
much uncertainty attends the various attempts which have been made to bring the
genera composing this section into anything like a systematic arrangement.
Crotch placed under this subfamily three “groups,” the Ortaliz, Azye, and Exo-
plectree proper; but Chapuis, on the other hand, places Azya and Froplectra, with
Cryptogonus and Bucolus, under his Bucolites, making another subfamily, Chnoodites,
to include Chnoodes (which is, in fact, scarcely distinct from Exroplectra), and Ortaliites,
for Ortalia and five allied genera. Without expressing any view on the genera
from the East Indian and Australian regions, such as Bucolus and Cryptogonus, we
here unite the genera occurring in Central America belonging to these different divisions
under the Exoplectrides. Chapuis says of the ‘ Chnoodites’ and of the ‘ Bucolites,’ that
they are but in fact pubescent Hyperaspides. I consider the Exoplectrides, as we here
adopt the term, quite as nearly allied to the Chilocorides, of which, indeed, Exoplectra
has very much the form, and the elytra are very similarly constructed with deeply
inclined epipleure.
AZYA.
Azya, Mulsant, Spec. Col. Trim. sécur. p. 928 (1850) ; Crotch, Rev. Coccin. p. 279; Chapuis,
Gen. Col. xii. p. 240.
Five species of Azya have been described, all from Central or South America, with
the exception that one is from Guadeloupe. ‘They are blue or blackish-blue insects,
clothed with a fine pubescence, which is often denuded on a patch on the elytra.

An examination of the types shows that the three names quoted above belong to one
species. The greater or less distinctness of the black patch on each elytron depends
very much on the freshness of the specimens. The tibie, especially the front pair,
have a dilatation at the apex, besides that near the middle, and so the front pair appear
to have two tooth-like expansions; by this character they may easily be distinguished
from Exoplectre, as well as by the very fine and close punctuation, and by the fine
marginal line on the base of the thorax in front of the scutellum. |
A large number of Azya luteipes have been received by us; it occurred especially
abundantly at Capetillo. A. lwteipes is very variable in size.

Hab. Mexico, Acapulco in Guerrero (Hége).—Soura AMERICA, Cayenne !?, Monte
Video #, Chili ?.
This species only differs from A, luteipes in having the breast red, and I do not think
it can be regarded as more than a colour-variety, especially as the specimens referred
to it by Crotch from Chili and Monte Video fail in this respect, the one from Chili
having the sterna piceous, and that from Monte Video being absolutely as in A. luteipes.
There is, however, among specimens of the latter collected by Hoge at Acapulco, an
example with the breast entirely red, and it would be well to examine more specimens
of this kind before sinking the name as a synonym.
LADORIA.
Ladoria, Mulsant, Spec. Col. Trim. sécur. p. 928 (1850) ; Crotch, Rev. Coccin. p. 280; Chapuis,
Gen. Col. xi. p. 222. .
The Ladorie are very like the species of Azya, but have the tibiae not widened into
a tooth-like expansion ; they are, however, compressed externally, with the edge flattened,
the ciliated margins forming a sort of groove for the reception of the tarsi when folded
back. The eyes are not cut out opposite the insertion of the antenne. The base of
the thorax is not margined. The epipleure of the elytra have a small rather obsolete
fovea for the hind tibie. The claws are biid.
Ladoria is very close to Chnoodes ; indeed I can hardly think it distinct, the differences
relied on being very small and of rather specific than generic value.
Crotch added two species from South America to the one described by Mulsant.
- LADORIA.—EXOPLECTRA. 218
1. Ladoria desarmata.
Laderia desarmata; Muls. Spec. Col. Trim. sécur. p- 928+; Crotch, Rev. Coccin. p. 280°.
Hab. Mexico, Toxpam (Sallé); Panama, Bugaba (Champion).—Braziu ! 2 ; AMAZONS,
~ §. Paulo 2,
\
Ladoria desarmata, apart from the generic character, very much resembles Azya
luteipes; but is usually of a more obscure tint, and the denuded patch on the elytra
is common to both on the middle of the suture. The type is in the Cambridge collec-
tion, and the examples I refer to this species agree with it. Crotch? quotes other
South-American localities, but the examples in his collection on which these were
founded must be referred to other species. .
2. Ladoria delphinz. (Tab. XI. fig. 25.)
Orbicularis fere hemisphericus, dense tenuiter griseo-pubescens, fulva; prothoracis disco elytrisque obscure
cyaneis, his anguste rufo-marginatis Juxta suturam quasi denudatis; metasterno abdominisque basi
nigricantibus. Long. 4-5 millim.
Hab. Mexico, Vera Cruz, Toxpam (Salié), Acapulco, Jalapa, Oaxaca (Hége), Teapa
in Tabasco (H. H. Smith).
Head, thorax, and elytra very finely and closely punctured, thickly clothed with a
short grey pubescence, which reflects the light differently as the insect is viewed, so that
the upper part appears more denuded of pubescence than it really is. The head and
the sides and front margin of the thorax are red in all the examples that I have seen,
and the elytra are very narrowly margined with the same colour ; occasionally the disk
of each elytron is very indeterminately reddish. The body beneath and legs are wholly
red, with the exception that the middle of the metasternum is blackish, and in some
examples this colour extends to the base of the abdomen. There are three examples
of this species in Sallé’s collection bearing the name under which I describe it; Hoge
sent about six, three of which were from Acapulco, and Mr. H. H. Smith obtained one
at the latter locality. |
Ladoria delphine is on the average larger than L. desarmata; it is clothed with a
very fine but dense grey pubescence, the sutural region alone appearing black and
shining. |
We figure a specimen from Toxpam.
| EXOPLECTRA.
Exoplectra, Chevrolat, in d’Orbigny’s Dict. Univ. d’ Hist. Nat. v. p. 545 (1844) ; Mulsant, Spec. Col.
Trim. sécur. p. 916; Crotch, Rev. Coccin. p. 284; Chapuis, Gen. Col. xii. p. 241.
- The Exoplectre are often very like Azyw, but some are of a different colour, being
red all over and with spotted elytra. They have the tibiae dentate, but the claws are
bifid, and the tooth is of a different kind from that in Azya, being a broad, angular

dilatation near the base. The epipleure of the elytra have the inner margin deeply
divided, as in Chilocorus, to which genus Exoplectra seems otherwise allied. _
Crotch records eighteen species, all American, and it does not appear that any
species occurs further north than Mexico. .
1. Exoplectra tibialis.
Ezxoplectra tibialis, Muls. Spec. Col. Trim. sécur. p. 917’; Crotch, Rev. Coccin. p. 284°.
Hab. Mexico!2, Omilteme in Guerrero 8000 feet (H. H. Smith).
The type, which is in Crotch’s collection, now before me, appears to be a female
example ; it is the only exponent of ZF. t¢bialis which I have seen, with the exception
of a single male from Omilteme, which I think should be referred to this species. The
legs are dark, almost black, but inclining to be fuscous in both the type and in our
example, and both are rather oblong, but in our specimen the thorax is broadly red at
the sides, as seems often to be the case in the males of this genus. The head, middle
of the thorax, and elytra are fuscous-black, clothed with a sparse grey pubescence.
2. Exoplectra stevensi.
Exoplectra stevensi, Muls. Spec. Col. Trim. sécur. p. 921°; Crotch, Rev. Coccin. p. 285 *.
Hab. Mexico}, Acapulco and Iguala in Guerrero (Hége); Guatemaua, Coban in
Vera Paz (Conradt).
The males have the thorax broadly red at the sides, the legs are red in both sexes,
the elytra have a brassy reflection, which is most conspicuous in the males; it is very
liable to oxidize, giving rise to other metallic tints.
Four examples.
8. Exoplectra subenescens (Tab. XI. fig. 26.) .
Nigra, elytris subseneis, ore, prothoracis lateribus late, abdomine pedibusque rufis. Long. 45-5 millim.
Hab. Mexico, Ventanas in Durango (Hoge).
Above very like Ladoria delphine, but to be distinguished by the elytra not being
margined with red (as well, of course, as by the dentate tibie), and the elytra have a
distinctly brassy tint. £. subenescens is about the size of the Colombian £. consen-
tanea, but has a black head, and the sides of the thorax are very much more widely
red. The whole upper surface is rather densely clothed with a very short grey pubes-
cence. The punctuation of the elytra is very close and fine, but uniform. The mouth,
underside of the prothorax, and abdomen are red, the breast is pitchy-black, but shading
off indeterminately, and the base of the abdomen is pitchy-red, there is, however, no
greenish or brassy tint on the underside.
Seven specimens.

Hab. Guatemaa, San Gerdénimo (Champion).
Very convex, nearly orbicular; head black ; prothorax and elytra black, with a faint
brassy tint, the former very closely and finely punctured, the latter distinctly (and
compared with E. subenescens) rather more sparsely punctured; the front margin of
the prothorax rather more deeply emarginate than in L. swbenescens, and only the inner
side of the front angle with a very small red linear mark which runs inside the reflexed
margin of the angle itself. The underside is black, the abdomen clear red, with the ex-
ception of the first segment, which has the intercostal process and base narrowly black.
Two specimens ; perhaps both are females, and the male may have the thorax with
the sides more broadly red.

Chnoodes is very nearly allied to Exoplectra.
Crotch refers six species to this genus, one of which occurs in our district, the others
being South American. Eight other species he includes in Dapolia ; but the distinction
is not clear, and I treat them here as being congeneric.

This species is the Chnoodes roseipes (Muls.) of Sallé’s collection. Crotch’s type is a
specimen from Deyrolle’s collection without locality, that assigned to it being only a
surmise. Chnoodes sanguinipes is about the size of Exoplectra cruentipes. It is
scarcely so convex as that insect. The head and first segment of the abdomen are
dark in some individuals, probably the females. There were five examples of it in
Sallé’s collection, and if not common it seems to have been met with on several
occasions, especially in Mexico, whence Crotch’s example probably came.
3. Chnoodes cinctipennis.
sanguineo-rafus, nitidus, parce brevissime pubescens, creberrime distinote leviter punctatus, elytrorum disco
nigro-eneo. Long. 24-3 millim.
Hab. Guaremata, Chiacam, San Juan, and Tamahu in Vera Paz (Champion) ; PANAMA,
Bugaba, Volcan de Chiriqui (Champion).
Of the size of C. terminalis, and with the pubescence, as in that species, very fine
and often quite denuded on the disc of the elytra. The whole of the body is red, the
breast and middle of the abdomen being only indistinctly pitchy. The elytra are
black, very shining, with a bronze or greenish reflection, the margin (excepting at the
base near the suture) being widely red, more broadly so at their apex. The scutellum
is red, at least in the middle, in bright and fresh examples wholly sO.
About twenty examples of this Chnoodes were obtained by Mr. Champion.
4, Chnoodes bipunctatus.
Rufus, dense brevissime pubescens; capite (labro rufo), prothorace (angulis anticis pretermissis) elytrisque
nigris, his puncto singulo in utroque juxta suturam mediano rufo, vix punctatis. Long. 3} millim.
Hab. Mexico, Iguala in Guerrero (Hége).
Above black, scarcely visibly punctured, but. not very shining, being densely clothed
with a very short and fine grey pubescence. The head is quite even, with rather large
eyes ; the mouth and appendages are red. The thorax has the front angles very much
deflexed and red; and the body beneath and legs are also red, the breast only being a
little obscure in tint. The elytra are black, but have each a rather ill-defined and
obscure, oblong, small red spot about the middle and near the suture. I have only
seen the single example described above. It is somewhat doubtfully of this genus.
5. Chnoodes decipiens.
Orbicularis, niger, nitidus, densius pube brevi micante, in dorso denudato, vestitus; crebre ac distincte sed
minute punctatus ; capite, abdomine pedibusque sanguineis, prothoracis margine antico et laterali tenuiter

resemblance to an Azya, when the denuded patch is observable as it is in fine speci-
mens ; while others appear almost glabrous, owing to the pubescence being nearly all
rubbed off. Of course the structure of the tibiz will always separate it, and it is in
addition much blacker, having, in fact, only a very faint metallic tint. The style of
punctuation is also characteristic of this genus.
Five specimens.

Crotch (loc. cit.) refers examples of a Dioria from Mexico to D. setigera, Muls., and
states that he had not seen D. sordida; but in the Cambridge Collection are several
examples, one labelled “sordida” in his own handwriting, from Deyrolle’s collection, from
Yucatan, whereas of D. setigera there are two only from Chili. They are closely allied,
perhaps not distinct species ; I therefore retain the name D. sordida for our insect.
Subfam. ORTALIDES.
The Ortaliides are generally distinguished by their large finely-facetted eyes, which
occupy a vertical position on the sides of the head, and by a coarse and broken style of
punctuation. At present two genera only have been referred to the subfamily from the
New World, viz. Zenoria and Pseudoladoria, Crotch. The typical species of Ortalia
are, according to Mulsant, those found in Madagascar, but others occur in the Eastern
Tropics.
The Ortaliides have the epistome not emarginate in front, in which they are said by
Chapuis to differ from the Chnoodides. I cannot, however, follow the ‘distinction.
Some remarkable insects, for which new generic divisions must be proposed, are here
referred to the group.

often denuded in a patch. The tibie are quite simple; the claws simple (they are
said to be bifid in Ortalia and Zenoria).
1. Neaporia plagioderina. (Tab. XII. fig. 2.)
Ferruginea, capite prothoraceque testaceis, hoc medio, illo basi infuscatis; elytris saturate cxruleis, crebre
fortiter punctatis, apice tenuiter rufo. Long. 4 millim.
Hab. Panama, Bugaba (Champion).
Orbicular, somewhat depressed ; head and thorax yellow, but clouded with black at
the base, and in the centre from the front to the base in the latter very finely punc-
tured. The thorax narrow in front, the sides but little rounded, the front angles
produced and depressed, neatly fitting the eyes, which, however, owing to their large
size, can, I think, hardly be withdrawn; it is very transverse and arcuate, the base
gently bisinuate and finely margined. The scutellum is large and black. The elytra
have a depression on each side of the scutellum extending a little way down the suture ;
the callus is distinct, as in Poria; their sides are very finely margined, not at all expla-
nate, sinuate for the reception of the hind coxe.
One example.
2. Neaporia indagator. (Tab. XII. fig. 3.)
Testaceo-ferruginea, superne nigro-czrulea, ore epistomateque ferrugineis; prothorace brevi, tenuiter, elytris
fortiter crebre punctatis. Long. 3 millim.

Var.? Prothoracis angulis anticis testaceis.
Hab. Guatema.a, San Isidro, Volcan de ‘Atitlan (Champion).
Upperside dark indigo-blue, thickly clothed with silvery-grey pubescence, which is
generally more or less denuded on the front and middle of the elytra. The mouth and
front of the epistome, mouth-organs, antenne, legs, and body are ferruginous; the
breast darker and coarsely punctured. The head and prothorax are very finely, the |
elytra strongly and sparsely, punctured; the punctures on the latter are distinct |
points, sometimes confluent, and becoming closer towards the sides. ‘The prothorax is
very short, arcuate in form, the front angles being prominent and depressed ; the
whole width is four times the length. The scutellum is distinct and triangular,
punctured, and black. The epipleure are indistinctly yellowish, horizontally sinuate,
and slightly fossulate for the reception of the hind femora.
Six examples of the type, and a single specimen of the variety.
NEAPORIA. 219
8. Neaporia cribrata. (Tab. XII. fig. 4.)
Ore, antennis, pedibus corporeque infra ferrugineis ; capite prothoraceque nigris, fortiter crebre, illo confluenter
punctatis ; elytris lete ceruleis, parcius fortissime punctatis. Long. 2°5 millim.
Hab. Mexico, Teapa in Tabasco (H. H. Smith).
Of the same form as WV. indagator, but less pubescent and more strongly and deeply
punctured, especially as regards the head and thorax. The palpi are stout, about as
long as the head, their terminal joint long and feebly securiform. The antenne are
very short, not longer than half the eye. The prothorax is as short and wide as in
N. indagator; its front angles project about half round the eye (when the head is
extended); the sides are a little reflexed and very finely margined; the punctuation is
very deep and here and there confluent. The elytra are of a beautiful steel-blue, very
sparingly pubescent. A single example.
4, Neaporia cerulea.
Ore, antennis pedibusque ferrugineis; corpore subtus nigro vel piceo, superne nigro-ceruleo, nitido, parum
pubescente ; capite prothoraceque subtilissime, elytris fortius punctatis. Long. 2 millim.
Hab. Panama, Bugaba (Champion).
Smaller and more orbiculate than NW. indagator, and differing, moreover, in the
following respects :—It is less pubescent ; the thorax is not so short, and has the sides
converging in front, but the front angles though acute are less prominent, and there-
fore the whole thorax is not arcuate ; the base is less rounded, the hind angles being
quite distinct. The body beneath is black. The sides of the elytra are uarrowly
reflexed.
5. Neaporia metallica. (Tab. XII. fig. 5.)
Oblongo-ovata, subdepressa, supra viridi-metallica nitida, parce pubescens; prothorace brevissimo, cum capite
erebre distincte minute, elytris parcius et profundius punctatis ; corpore subtus, palpis pedibusque piceis,
his articulo tertio, illis apicali nigrescentibus ; elytris singulis macula magna subrotundata rufa. Long.
2-3 millim. .
Hab. Panama, Bugaba, Volcan de Chiriqui 3000 to 4000 feet, Tolé (Champion).
Head, especially the epistoma, golden pubescent; palpi yellow at their base, the
apical joint and the tip of the second joint blackish ; antenne very short, yellowish.
Thorax very short and very wide, quite four times as broad as long, with rounded sides ;
the margins are flattened and reflexed, the front angles acute and depressed, the base
with a very fine marginal line; sparingly pubescent. The elytra are oblong, with
straight sides, but their apex is widely rounded; they are shining metallic-green or
dark blue, with a brassy reflection ; their margins are finely reflexed ; the punctuation
is sparse but distinct ; the pubescence is sparse and very fine, nowhere hiding the
surface, but uniform and velvety. The yellow spots on the elytra are not of the same
: size, that on the left being large and transverse, while the one on the right is rather

220 COCCINELLIDZ.
obsolete. The legs are pitchy-black at their bases, with yellow tibie and tarsi, of
which, however, the bilobed apex is blackish.
This is a less convex insect than the preceding species, and has also the elytra more
parallel on their sides. In the shortness of the thorax, the short antenne, stout palpi,
and other characters it agrees well with them. In one example from Bugaba the red
spot is suffused so as to involve the whole disk of the elytra in a common spot reaching
entirely across the wing-cases, but nearly separated at the suture.
6. Neaporia argentifrons. (Tab. XII. figg. 6; 6 @, maxillary palpus.)
Breviter oblonga, rufo-picea, nitida, tenuiter pubescens ; capite prothoraceque viridibus, subtilissime punctatis,
hoc transverso, marginibus lateralibus leviter anguste reflexis, illo inter oculos argenteo-albido, vittis
duabus nigro-viridibus; scutello elytrisque castaneis, his parcius punctatis. Long. 2°5-3 millim.
Hab. Mexico, Toxpam (Sailé).
Var. Elytris pone medium et disco usque ad humeros indeterminate viridibus.
Hab. Guatemata, Zapote (Champion).
This species is nearly of the same size and form as NV. metallica, and, considering the
single example from Zapote as a variety, it may probably be a more northerly form of
that species, differing mainly in colour. The head has the whole of the front and
epistome shining silvery-white, with two posteriorly-abbreviated dark vitte; and this is
so also in the Zapote variety. ‘The thorax has the usual oblique sulcus separating the
middle portion which receives the head from the produced front angles. ‘The palpi
have the terminal joint blackish.
There are two examples from Toxpam, one of which we figure.
7. Neaporia amabilis. (Tab. XII. fig. 7.)
Breviter oblonga, rufo-picea, nitidissima, parce profunde punctata; capite nigro-piceo, epistomate palpisque
rufo-piceis ; prothorace viridi, transverso, angulis anticis valde prominulis, lateribus reflexis, disco parce
minute punctato ; elytris cupreo-purpureis, parcius punctatis ; pedibus rufis. Long. 2 millim.
Hab. Guatemata, El Tumbador 2500 feet (Champion).
The form of this species is very similar to that of MV. metallica and JN. argentifrons.
The head is more coarsely punctured than in either of them; it is pitchy-black tinged
with green, with the mouth and palpi pitchy-red. The thorax has its disk more even,
there being less indication of an oblique sulcus, and it is of a dark green; there is no
pubescence to be seen on the whole upper surface. The elytra are of a brilliant
coppery-purple, inclining to be castaneous; and in this respect VY. amabilis is somewhat
like an example of WV. argentifrons from Toxpam, but the punctures are much sparser
and larger, and it is scarcely half the bulk of the latter. The colour of the elytra
probably varies.
Only one specimen has been received.
NEAPORIA. 221
8. Neaporia unipunctata. (Tab. XII. fig. 8.)
Valde convexa, suborbicularis, nitida, nigro-picea, superne subcerulea; capite prothoraceque subtiliter, elytris
fortius punctatis, his macula magna in singulis, abdominis apice pedibusque rufis. Long. 1°25 millim.
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).
Somewhat resembling the smaller examples of NV. metallica, but strongly convex, the
margins of the elytra being almost hidden from above. The thorax is quite of a
different form from that of WV. metallica, being less wide, apparently about three times
the length ; the latter, however, seems actually greater than in WV. metallica; it is also
more shining and much more convex, and its front angles are more contracted and less
explanate. The colour, moreover, is different, and the legs and tip of the abdomen
are red.
9. Neaporia pubescens. (Tab. XII. fig. 9.)
Breviter oblonga, picea, pube brevi erecta dense vestita; prothorace brevi, valde transverso, rufo, crebre
punctato; elytris cerulescentibus, macula magna discoidali haud bene discreta rufa, parcius sed crebre
punctatis, punctis hic illic transversim confluentibus. Long. 2°5 millim.
Hab. Panama, Volcan de Chiriqui 2600 to 3000 feet (Champion).
This insect is allied to 1. metallica, but is more convex, more densely pubescent,
and differently coloured to that species. The thorax is in form very like that of
N. metallica; its front angles are very prominent, forming a covering for the large
eyes, which are no doubt, in repose, partially withdrawn behind them; the lateral
margins are only very narrowly reflexed, and there is an oblique sulcus half across
the disk behind the eyes. The epipleure are sinuate for the reception of the hind
femora. The elytra, though bluish, have a tendency to become pitchy-red, and the
legs are of that colour.
One example.
10. Neaporia rugosa. (Tab. XII. tig. 10.)
Convexa, oblongo-ovata, nigro-picea, superne atro-cerulea, crebre fortiter, elytris subrugose punctatis, his
macula oblonga discoidali in singulis sanguinea ; pedibus rufis. Long. 1°25 millim.
Hab. Panama, Tolé (Champion).
This insect, though superficially very like V. unipunctata, will, I think, prove to be
abundantly distinct. ‘The form of the thorax is more that of V. metallica, viz. wide,
very short, with prominent rather explanate front angles, and a depression immediately
behind the eyes. It is, however, in the punctuation that it differs very clearly from its
allies, that of the thorax being as strong and distinct as that of the head, while that of
the elytra is more close and more dense than in any of the other species here described.
The mouth and tip of the abdomen are red. ‘he elytra are distinctly pubescent.
One example.
222 COCCINELLIDZ.
11. Neaporia compta. (Tab. XII. fig. 11.)
Breviter ovalis, fere orbicularis, rufa; capite prothoraceque subtiliter, elytris ceeruleis concinne fortius punctatis.
Long. 2 millim.
Hab. Panama, Volcan de Chiriqui (Champion).
Readily distinguished from any other species of the genus here described by its colour,
which is wholly dark ferruginous-red, with the exception of the elytra. The latter are
deep blue, with the sutural angle very slightly red. The scutellum is obscure, but is
plainly reddish. The thorax is short, about three times as wide as long. The whole
insect is moderately convex, clothed above with a short silvery pubescence ; the head
is very flat between the eyes; the puncturing of the head and thorax is very fine, but
quite visible, that of the elytra much more distinct, not deep, and rather stellate; the
tip of the elytra is very narrowly red, and the red pygidium (not quite covered) enhances
the red appearance of the apex.
12. Neaporia chiriquensis. (Tab. XII. fig. 12.)
Breviter oblonga, convexa, rufo-ferruginea; capite (ore epistomateque exceptis), prothorace elytrorumque
triente apicali nigro-ceruleis ; capite elytrisque parcius fortiter, prothorace subtiliter punctatis. Long.
2°5 millim.
Hab. Panama, Volcan de Chiriqui (Champion).
The head is very deeply and almost rugosely punctured. The thorax is very short, four
times as wide as long, the sides margined and reflexed, the front angles acute, depressed ;
the base has a very fine marginal line ; the punctuation, though quite visible, is very fine
and close. The scutellum is red. The elytra are rich deep red, but their apical third,
extending further on the disk than at the suture or on the sides, is blue-black; the
punctures are large, rather stellate, sparse, but thicker and here and there confluent
near the scutellum; the narrowly reflexed margin is red all round. ‘There is scarcely
any pubescence visible in the single example before me.
13. Neaporia guatemalana.
Oblonga, nigra, subnitida, breviter canescens; elytris subceruleis, ore, pedibus abdominisque apice rufis ; pro-
thorace brevi, transverso, cum capite creberrime punctato, elytris parcius sed crebre punctatis. Long.
2 millim.
Hab. GuateMata, Capetillo, Duefias, San Gerdnimo (Champion).
Var.? Parum angustior, prothorace interdum piceo, elytris subeeneis.
Hab. Mexico, Jalapa (Hoge), Amula in Guerrero 6000 feet (H. H. Smith).
More oblong than NV. cerulea, with the thorax more transverse, being formed as in
N. metallica and its allies, the base truncate, a little sinuate, the front angles promi-
nent and reaching to the front of the eyes when the head is depressed ; there is a very
small punctiform depression behind the eyes. The whole upper surface is rather
NEAPORIA. 223
densely hoary. In the Mexican examples it is denser and more unevenly combed,
giving a mottled look. The example from Amula is wholly piceous, probably less
mature. Possibly these represent a different species, but I cannot separate them at
present.
14. Neaporia celestis. (Tab. XII. fig. 13.)
Oblonga, nigra, nitida, capite prothoraceque metallico-viridibus subtiliter, elytris lete cwruleis parce punctatis ;
ore, pedibus abdominisque apice rufis ; prothorace valde transverso, lateribus anguste reflexis rufescentibus.
Long. 2 millim.
Hab. Panama, Bugaba, Volcan de Chiriqui 4000 to 6000 feet (Champion).
This little species may be distinguished from J. cwrulea by the same characters as
NV. guatemalana. From the latter the more brilliant coloration and the reflexed and
reddish margin of the thorax, and the certainly more reflexed and wider margins of the
elytra and their rather more sparse punctuation, will enable it to be separated.
Two specimens.
15. Neaporia viridescens.
Oblonga, nitida, nigra, tenuiter pubescens; superne viridi-metallica, prothorace transverso, margine laterali
leviter reflexo; capite prothoraceque creberrime, elytris parcius punctatis. Long. 1-5 millim.
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion).
Smaller than any Neaporia I have seen, with the exception of NV. cuprea. In its
form and general characters it agrees pretty closely with WV. celestis; but, besides the
small size, the black legs seem to distinguish it as a species. ‘The anterior femora are
pitchy at their bases.
One example.
16. Neaporia cuprea. (Tab. XII. fig. 14.)
Oblonga, nitida, nigra, vix pubescens; capite prothoraceque nigro-ceruleis parcius distincte, elytris cupreis
parce punctatis; pedibus nigris, tarsis fuscis. Long. 1°25 millim.
Hab. Guatemata, San Gerdnimo (Champion).
This is the smallest example of a Neaporia I have seen. It differs from WV. viri-
descens in being narrower, the thorax especially so, its front angles being less expanded,
the sides less reflexed, the surface more even, there being no oblique fossa behind the
eyes, and more “cribrate,” ¢. ¢. more distinctly punctate, and the same remark applies
to the punctuation of the head. The elytra are also very distinctly punctured ; they
are coppery-purple, violet at the margins. The legs are black, with brownish-yellow
tibie and tarsi. ‘The palpi are quite black.
Although we have received only one example of this little Meaporia, there is no
doubt it represents a distinct species. The want of pubescence may, of course, be

owing to its condition, but as a very short black pile is visible it is probably quite
normal,
ORTALISTES.
Corpus oblongo-ovatum, valde convexum. Tibi simplices. Fossule coxales abdominales segmento longitu-
dine equales, extus aperte. Antenne perbreves.—
I propose this genus for two species which, apart from the form of the whole insect,
do not present any very striking positive characters. The body is rather suggestive of
that of Brachyacantha; the head is nearly sunk in the thorax; the elytra very obtuse
behind, and not covering the apex of the abdomen.
1. Ortalistes obesus. (Tab. XII. fig. 15.)
Breviter ovatus, valde convexus, ferrugineus ; capite prothoraceque nigris, hoc limbo laterali, illo ore, antennis

tatis. Long. 3°5 millim.
Hab. Panama, Bugaba, David (Champion).
The pubescence of this insect is extremely fine and not easy tosee. The mesosternum
and a small part of the sterna in front and behind it are blackish, but the scutellum is
red. The patch of the elytra occupies two-thirds of their surface, leaving the humeral
region from the scutellum obliquely to the middle of the sides, and the apical margin
from that point, red. In one specimen this margin unites rather widely with the basal
portion, and the whole base for one-third its length is red. ‘The thorax is short,
contracted in front, not deeply cut out, more distinctly punctured than the elytra.
Three specimens.
2. Ortalistes rubidus.

This insect appears to differ from the last in its rather smaller size, wholly ferru-
ginous colour, and by the thorax being hardly visibly punctate.
Two specimens.

and equal on the thorax and elytra. The scutellum is red or brownish. The elytra
are entirely chestnut-red, but a little paler towards their apices. The pubescence is
so fine that it is often worn off. The amount of black on the thorax varies: in some
examples the greater part is black, the sides only being rather indefinitely white ; in
others the white extends like a round spot for a third of the width.
4, Ortalistes pexus.
O. germano quoad formam et staturam similis et affinis; piceus, minute sed distincte punctatus; pube brevi

Senahu, Tamahu, Sabo, and San Juan in Vera Paz ( Champion) ; Nicaragua, Chontales

Hardly so broad, especially across the thorax, as 0. germanus, and perhaps a little
more distinctly punctured. The colour is different, being uniform and of a dark
pitchy-brown tint. The pubescence is not only more distinct, but seems of a different
quality, and gives the impression of being brushed away from the suture on each
side, thus reflecting the light as the insect is turned in different directions.
Specimens from Nicaragua and the Pearl Islands are almost black.

It is only when seen under favourable circumstances that this little insect appears
pubescent ; it is so closely punctured as to be semiopaque. The thorax, the base and
margin of the elytra, as widely as one third of their breadth and more widely still at
the apex, and the head and body in the female, are black. The very short antenne
and trophi are always yellow, as are the legs. We have received one example of the
male, viz. the one from Bugaba, and a female from each of the other localities.
There is a species of Cryptognatha very similarly coloured to this insect.
Subfam. SCY MNIDES.
The Scymnides consist almost entirely of the genus Scymnus, one of the most
generalized types of the Coccinellide. ‘The genus itself has been divided by Mulsant,
but he did not give his divisions, founded on the amount of development of the coxal
fossettes, more than subordinate rank. They have, however, been adopted by recent
European writers, with whom the ultimate analysis of minute characters is of higher
importance than the synthesis of allied forms.
BIOL. CENTR.-AMER., Coleopt., Vol. VII., March 1897. 9 Gt
226 COCCINELLID. ~
As is usual with very generalized types, Scymnus is represented by a large number
of species in every part of the globe, often very closely allied to each other even when
coming from distant parts. Chapuis has, in the ‘Genera des Coléoptéres,’ very much
restricted the group. I should go-still further and eliminate from it the Rhizobiides,
a subfamily separated by several peculiarities, and not of such universal distribution.
SCYMNUS.
Scymnus, Kugelann, in Schneider’s Mag. i. p. 545 (1794).
Scymnus is a genus consisting of a host of small species, distributed in every part of
the world, found on trees and on low herbage, living on small Aphides and possibly
Coccide.

There are two examples of this, which is a larger, broader, and more pubescent
insect than the one referred to S. volgus, and the elytra have a distinctly brassy tinge.
The body beneath is also wholly black, with the exception of the head (with all the
mouth-organs) and the thorax. The genitalia are obtruded in one of the examples and
are red. ‘The thorax is three times as wide as long, with rather prominent front
angles (in the specimen here referred to S. volgus the front margin is nearly straight),
the margin being broadly cut out in front. The abdominal coxal fossettes appear to
me to be ill defined externally, the internal side reaching almost to the edge of the
segment.

The head, thorax, legs, and apical half of the abdomen are chestnut-red; the elytra
black, not pubescent, impressed with minute, but distinct, and not very close punctures.
In one example from the Volean de Chiriqui the scutellum is red. The insect has
very much the appearance of a Cryptognatha found at David, but from which its more
oblong form and longer thorax will serve to distinguish it. I have seen an insect
which appears to belong to this species named “ S. volgus.” |
The example from Caracas in the late Mr. Crotch’s collection, from that of Reiche,
is not a true Scymnus. There is therefore some doubt about the identification.

Broadly ovate, of similar form to S. apicalis, Muls., but rather smaller, wholly
ferruginous, with a grey, rather close pubescence. The sculpture of the elytra exhibits
no trace of sulcation or of striation, but is very finely and closely punctate. The eyes
are rather strongly facetted. Of the wholly yellow Scymni known to me, this is the
largest and broadest ; the European S. abietis is a more oblong and less convex insect.
The specimen from Chilpancingo, which has the breast blackish, may possibly represent
a distinct species. It appears to me to belong to the same section as S. apicalis.

The type of this species from Reiche’s collection, now in that of the Cambridge
Museum, is before me, and examples from the above localities agree with it. It is
very near S. cinctus, Lec., and S. lecontit, Crotch, which Horn does not consider distinct.
We figure a specimen from San Pedro.
6. Scymnus apicalis. (Tab. XII. fig. 21.)
Scymnus apicalis, Muls. Spec. Col. Trim. sécur. p. 987'; Crotch, Rev. Coccin. p. 271°.
Hab. Mexico! 2, Chilpancingo and Amula in Guerrero, Cuernavaca in Morelos
(H. H. Smith), Ventanas in Durango and Acapulco (Hége) ; GuaTeMaLa, Quezaltenango,
Guatemala city (Champion).
The distinguishing characters of this species, which is somewhat similar to the one
described as S. horni, are its rather larger size (length 2-23 millim.), the wider extent
of the orange-red apex of the elytra and of the abdomen, of which only two segments
at the base are decidedly black, and the faint indications of rows among the punctures
at the base of the elytra near the suture, which may therefore be termed substriate at
that part. I have seen a few examples from Amula with blackish legs and with
blackish genitalia (although the abdomen is red), apparently females, the heads being,
however, obscurely red.
Scymnus apicalis was described by Mulsant from specimens in Dejean’s collection ;
and as the first quoted of these is from ‘* Mexico,” it will be better to exclude the
supposed South-American specimens. It does not appear to have been identified by
Horn. A quasi-type in Crotch’s collection, with an H., and ‘* Pennsyl.” as locality, in
no way corresponds to the description and is quite valueless as a type. One from
Reiche’s collection is from Caracas, while three others with a label “* Yucatan,” but
which also bear the word “ Caracas,” are apparently not referable to Mulsant’s species.
I therefore propose that the present insect, which agrees fairly with the description,
and which we now figure, should be adopted to represent it.
Obs.—Crotch places S. apicalis as following S. auritulus, both in the ‘ Revision ’ and
in his collection: it is altogether a wider and more distinctly marked insect than that
species. About thirty examples are now before me.
7. Scymnus bugabensis.
Late orbicularis, niger, pedibus abdomineque obscure rufis, dense griseo-pubescens ; elytris fortiter punctatis,
juxta suturam seriebus duo vel tres punctorum magis distinctis, apice cuncolore; capite prothoraceque

Hab. Panama, Bugaba (Champion).
A very distinct species of Scymnus, being broader than any yet noticed, with the
elytra more distinctly punctured, and the striole approaching those of the genus
Sticholotis in distinctness. The head is red in some examples, black in the others;
SCYMNUS. 229
the eyes have a golden shining appearance, but in themselves are whitish or red; and
the extreme tip of the front angle of the thorax is reddish in some examples. The
pubescence is dense and shining, like that of Azya, but in many examples this is
entirely absent. The base of the thorax is sinuous, and has a very fine marginal line.
The metasternum is strongly, almost coarsely punctured in the middle, more closely
and more finely so at the sides. The legs and abdomen are dark brownish-red; the
coxal fossettes reach the margin of the first segment.
8. Scymnus auritulus.

Specimens from the localities quoted have been compared by me with the type from

The insect occurred abundantly in most of the localities mentioned.
9. Scymnus horni.

This insect is clearly very closely allied to the recently described S. ardelio, Horn
(Trans. Am. Ent. Soc. xxii. p. 105). It was sent to us from Sonora labelled “ Seymnus
marginicollis”: from that insect it differs (following Horn, loc. cit.) in having the legs
red; but it does not agree with S. ardelio, according to the description. The apex of
the elytra, in the great majority of the examples, is very narrowly red, as is also the
pygidium, with the last ventral segment. Specimens which are presumably females
have all the red parts more obscurely coloured, and the tips of the elytra and abdomen
nearly black. There is apparently no tubercule on the first ventral segment. The
insect is a true Pudlus.
10. Scymnus jansoni.
Suborbicularis, convexus, niger, parce pubescens, ore, antennis, prothoracis lateribus, elytrorum vitta abbreviata,

Var. elytris vitta deficiente.
230 COCCINELLID 4.
Hab. Mexico, Atoyac in Vera Cruz, Teapa in Tabasco (H. H. Smith); Nicaraaua,
Chontales (Janson).
The examples which I associate under this name agree in size, which is smaller
than that of S. auritulus, but rather larger than the European S. minimus, and in
having the sides of the thorax and apex of the elytra usually red. In some specimens
(as in those which present an obscure red vitta on the disk of the elytra) the tips are
not red. The whole of the mouth, the legs, including the trochanters, and the apex
of the abdomen are red; two segments at the base of the latter are blackish, but
passing so gradually into red that it is not possible to define the commencement of the
latter colour.
Obs.—In less matured examples the thorax may be yellow, with a basal cloudy spot,
and the vittee may be widened and paler, uniting on the suture before the apex, which
is cloudy.
11. Scymnus hogei.
Oblongus, densius fulvo-pubescens, prothoracis basi quam elytra angustiore, niger, subtilissime punctatus,

Hab. Mexico, Zacualtipan in Hidalgo (Hége).
Var.? Rufus, elytrorum basi, sutura apiceque indeterminate nigrescentibus.
Hab. Mexico, near the city ({ége).
The form is oblong, rather ovate, not narrowed behind, but with the thorax narrower
than the elytra, and not forming a continuous outline with them. The elytral vitta is
wider at the base, and for nearly half its length crutch-shaped, or like a long (, )
comma. The mouth, antenne, and legs are red.
The specimen which I think may be a variety of this insect, being precisely of the
saine form and size, has the base of the elytra blackish, this tint extending in a
triangular way down the suture and along the margin and at the apex, but indetermi-
nately. There is a single specimen only of each form.
12. Scymnus bisbinotatus. (Tab. XII. fig. 22.)

Hab. GuaTEMALA, Capetillo (Champion).
Rather broadly ovate, not very convex, the elytra wider in the middle than the
thorax, sparsely pubescent (but worn in the unique example), dark pitchy-black. The
elytra each have two dark red spots, one near the callus, and one, less distinct, near
the apex. The legs are testaceous, with the tips of the tarsi darker, and are rather
long and thin. The head and underside are pitchy-black. The coxal fossettes are
complete, not touching the hind margin of the segment.

Mas, capite, prothorace subtus et ad latera rufis.
Hab. Panama, San Miguel in the Pearl Islands (Champion).
This little species is very distinctly oval in form, pointed behind, and it is rather
strongly convex, and clothed with grey pubescence. The elytral red spot is placed at
about one-third from the apex and quite free; it is rather more transverse in the
female than in the male. The body beneath is almost wholly black ; the prothorax is
red in the male beneath, and with the sides indeterminately so, and the head is also
red in this sex. ‘The supposed female is smaller, and has the thorax and head black.
The legs have rather wide femora, receiving the tibize in grooves, and are wholly
orange-red. ‘There are but two specimens of this species. I cannot recall to mind
any Scymnus similarly marked.

Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guatemaa, Capetillo (Champion) ;
Panama, Volcan de Chiriqui, Pefia Blanca, Tolé (Champion).
This is a variable and perplexing species. The examples which I suppose to be the
males are more orbiculate and larger than the three others, which from their darker
heads appear to be females; and in these males(?) two have the elytra more or less
suffused with a blood-red discoidal patch, viz. one from Teapa and one from the Volcan
de Chiriqui, while one from the latter locality and one from Pefia Blanca have them
wholly black. The body beneath is black. The legs are yellow. The three females (%)
are one from Teapa, one from Capetillo, and one from Tolé; they have the thorax narrowed
in front, and its sides continuous in outline, or very nearly so, with that of the elytra.
S. coloratus has very much the appearance of an Ortalistes (especially of O. immersus),
and, indeed, I think it may have to be removed to that genus. ‘The distinction between
Scymnus and the allied genera is very slight, as may be seen by reference to Chapuis,
in Lacordaire’s ‘Genera des Coléoptéres,’ xii. p. 206.
The example from Pefia Blanca is more like that from Chiriqui, but is half the size.

232 COCCINELLID 2.
I have referred the Central-American examples to this species on the authority
of a specimen in Mr. Crotch’s collection, and on others I have seen so named,
rather than from their agreement with Mulsant’s description. The latter seems to
have been drawn from a female example, having the head black, and from either a
unique example or from quite insufficient material. Our examples, ten in number,
agree in having the head and thorax quite whitish-yellow. They are very variable in
size and colour, but are all rather pubescent, and have the elytra brown, blackish, or
black, with a red disk, or a faint red marking on each, and the apex always white,
except in those from Bugaba and the Pearl Islands.
Judging from examples in Crotch’s collection, the paler ones might be equally well
referred to S. tantillus or S. pallidipennis, Muls. (the specimen of the latter is the type),
the descriptions of which are inadequate and inconclusive.
At present I regard these names as indicating one widely spread and variable insect ;
but possibly our examples from Mexico and Guatemala are distinct from those from
Panama.
16. Scymnus mutatus.
Ovatus, capite, prothorace, pedibus abdomineque pallide testaceis; elytris nigris, macula magna discoidali

_ Hab. Panama, Pefia Blanca (Champion).
The single specimen from the Volcan de Chiriqui, which I take for the type of this
species, is a very distinctly marked and rather convex, finely pubescent insect, with the
head and thorax nearly white, the elytra dark pitchy-black, with a large, oval, and
rather obliquely placed orange spot on each. The underside, with the exception of
the breast, is luteous. The legs are testaceous. ‘The coxal fossettes are deep, but only
reach over half the segment. ‘The Mexican examples are doubtfully associated with it :
the one from Cuernavaca isa little smaller and has better defined pubescence ; the colour
and markings are very similar, and at the same time are very suggestive of those of
SCYMNUS. 233
S. jansont. The specimens from Teapa vary a good deal among themselves, the thorax
in some of them being white, without markings, in others with a more or less
developed spot on the base, with its apex sometimes reaching the front margin; all
these, with one exception, have the head white, deeply sunk in the thorax.
17. Scymnus granum.
Breviter ovatus, suborbicularis, niger, parce pubescens, pedibus rufis, subtiliter punctatus. Long. 1 millim.
Hab. GuatEMaLa, Duefias (Champion).
The two specimens of this minute insect agree in being wholly black, with the legs
red and the mouth-organs testaceous; the puncturing is just visible under a Cod-
dington-lens ; the pubescence is greyish, sparse, and irregularly upright. The outline is
tolerably uniform ; the thorax has rather straight sides, narrowing in front, and with
prominent front angles. It is less shining than the following species (S. grumus),
without being opaque.
In dealing with such very small insects in an obscure genus it is, I think, better to
abstain from attempting to describe details which can only be established on longer
series, and to give only such characters as are apparent and may enable other specimens
from the same locality to be recognized.
18. Scymnus grumus.
S. grano iterum similis et affinis, perparum major et nitidior; niger, nitidus, capite, pedibus, abdominis
elytrorumque apicibus tenuiter pallidis, parce pubescens, prothorace lato, antice haud multo angustiore.
Long. 1:2 millim. a
Hab. GuateMata, Capetillo (Champion).
A little larger than S. granum, and especially more shining; the pubescence is
apparently a good deal rubbed off, but the surface is smoother. The head is clear
yellow, and the legs are very pale, as is the abdomen, with the exception that the basal
portion is black in an indeterminate degree, but extending over two segments.
A specimen from Zapote perhaps belongs to the same species.
19. Scymnus corpusculus.
S. grano similis et affinis, oblongus, niger, nitidus, parce pubescens; capite, prothoracis lateribus, pedibus
elytrorumque apicibus tenuiter pallide rufis, feminz corpore obscuriore. Long. 1-5 millim.
Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith).
Rather more densely pubescent than S. granum, more parallel in form, and more
shining. The thorax is as wide in front as behind, and with acute, though depressed,
front angles. The head and sides of the thorax are red, and the front margin of the
latter is very narrowly pitchy-red in some examples. The puncturing is very fine,
scarcely visible under a Coddington-lens. The abdomen appears not to be red, as in
BIOL. CENTR.-AMER., Coleopt., Vol. VII., May 1897. 2 H*
234 COCCINELLID.
S. grumus, and in those examples I suppose to be females the head and thorax are
quite obscure. Of these three small species the present is the largest, it being also
more oblong than the others.
Eight examples are before me.
20. Scymnus aspersus. (Tab. XII. fig. 26.)
Breviter oblongus, luteus, pubescens, prothorace antice angustato, basi infuscato, vel medio indeterminate
fusco; elytris basi sutura, margine laterali ad medium ampliato, ante apicem desinente, punctogue
discoidali nigricantibus. Long. 1 millim.
Var. Prothorace saturatiore, elytris nigro-variegatis.
Hab. Mexico, Toxpam (Sallé), Teapa in Tabasco (H. H. Smith); GUATEMALA, near
the city, Duefias (Champion).
This little insect seems to be very variable. The two examples from Teapa appear
to have, at first sight, four spots on the elytra, but the basal ones are only prolongations
of the basal black on the disk. The black colour extends down the margin as far as
the posterior discoidal spot, and is there widened as if it would join it: in two
examples the spot returns in the form of a vitta, leaving only a vague yellow ring on
the elytra, the scutellar region being more widely suffused. The breast is pitchy.
This is one of the smallest of the Scymni, but is scarcely so small as S. grumus and its
allies.
Seven specimens. One from Teapa is figured.
21. Scymnus diversus.
Breviter oblongus, luteus, pubescens ; prothorace maculis duabus anterioribus, duabus posterioribus vel tribus
basalibus haud bene discretis fuscis; elytris plaga laterali pone medium provecta nigra, interdum
macula parva suturali postmediana. Long. 1 millim.
Hab. Guatemata, San Gerénimo and Cahabon in Vera Paz (Champion).
This insect in form and general appearance is very like S. aspersus; it is,
however, differently marked. The thorax in the example from San Gerénimo has
four distinct nearly black spots, and the elytra have a wide lateral blotch, extending
halfway across each elytron. There are indications of black markings here and there
on the elytra, one of which becomes a distinct spot on the suture at about one-third
from the apex.
In the example from Cahabon the thoracic spots are less distinct, but more wedge-
shaped, and there is in addition a central basal spot. The body beneath and legs are
yellow. |

VEDALIA.
Vedalia, Mulsant, Spec. Col. Trim. sécur. p. 905; Crotch, Rev. Coccin. p. 281.
The type of Vedalia is the Mexican insect recorded below, much confusion appearing
to have arisen by Crotch having associated Vedalia sieboldi with species from India
and elsewhere, which Mulsant placed, and as I think properly enough, in Rodolia.
Again, the characters of Vedalia, as given by Mulsant, are very unsatisfactory and even
illusory: that the tibie are rounded or angular on their exterior margin seems to me
an error of description. They are very flat, and shut partly into grooves of the femora;
but they are neither emarginate nor angular, and the association of these genera with
the Exoplectrides is quite erroneous. Vedalia, in fact, approaches nearest to Wovius,
a Palearctic genus occurring in Asia and Japan. The claws are bifid. The coxal
fossettes are well marked, nearly reaching the end of the segment, but not complete.

The examples from Guanajuato and Orizaba differ slightly from those from Yolotepec
in having the whole metasternum, with the epimera, and even the trochanters and
coxe, black, and the first-named have the black mark near the scutellum less developed.
Specimens in the Cambridge collection, one of which is typical, being the example
from Westwood, have the breast infuscate. ‘The antenne are scarcely longer than the
palpi, red, with an elongate, three-jointed club. The abdomen has six segments in the

narrow, flat, grooved at the inner edge for the reception of the margins of the abdomen
(in Rodolia they are wide and much inclined). —
Five examples. We figure one from Orizaba.
Subfam. EPIL ACH NIDES.
The Epilachnides form with the Scymnides the most generalized group of the
Coccinellide ; like them, they are found with very little modification of form in every
part of the world, and the great majority of the species belong to the typical genus
Epilachna, the subgenera Chnootriba from Africa, and Lasia and Cycnegetis from Europe,
being very little differentiated, the two latter containing but a single species each,
and Chnootriba only three.
In the Epilachnides, however, we meet with an important variation in habit, the
species being all phytophagous, feeding on the leaves of Solanacese and Cucurbitacee,
and the mandibles are tridentate. They are described as multidentate by Mulsant, but
in the species I have dissected (E. mexicana, E. borealis, E. abrupta) there is one sharp
spine-like tooth in addition to the bifid apex usual in the Coccinellide.
The species of this subfamily are (as I have observed in the generalized type of
other families) very subject to variation, and some of them, as Epilachna borealis, are
very widely distributed ; and the species are very little differentiated from each other,
rendering their determination often very difficult, the type of variation in one species
being repeated in other nearly related species inhabiting the same region.
EPILACHNA.
Epilachna, Chevrolat, in d’Orbigny’s Dict. Univ. Hist. Nat. v. p. 359 (1844).
About two hundred and forty species of this genus have been described, but the
names of a good many of these must be regarded as synonyms. ‘They are more
abundant in the tropics than in the temperate districts; on the other hand, some
species are found at elevations up to 8000 feet.
In Crotch’s “ Revision of the Coccinellide of the United States” [Trans. Am. Ent.
Soc. iv. pp. 363-382 (1873)] the genus Epilachna is altogether omitted, and it would
appear from the remarks of Mr. J. B. Smith (Ent. News, 1893, p. 197) that one at least
of the species is gradually extending over the Eastern United States. Three are given
from North America in Henshaw’s ‘ Catalogue ’ (1885).
A. Elytra widest a little below the shoulders.
1. Epilachna abrupta. (Tab. XIII. fig. 1.)
Oblonga, subovata, nigra, nitida; elytris testaceis, dense minute punctatis, sutura margineque nigris, hac
. interdum in maculam medianam ampliata. Long. 10-12 millim.
EPILACHNA. 237
Hab. Costa Rica, Volcan de Irazu 6000 to 7000 feet (Rogers); Panama, Bugaba,
Volcan de Chiriqui 4000 to 6000 feet (Champion).
Head, thorax, body beneath, the margins, epipleure, and suture of the elytra jet-
black; the disk of the elytra pale testaceous (in life pearly and metallic), often with a
spot united with the margin in the middle, or a slight widening of the black in that
part looking like the commencement of a fascia. ‘The margin of the elytra is expanded
round its entire length, the expanded part being a little rugose. The coxal fossettes
are not very distinctly defined. This insect belongs to the ‘ £. proteus” group of the
genus, but appears quite distinct in form, as well as in the sparseness of the pubescence,
from any of the numerous varieties of that species. I have a very similar but distinct
insect from Colombia.
Mr. Champion met with a long series of examples on the Volcan de Chiriqui, feeding
‘on a very spiny species of Solanaceous plant, and Mr. Rogers sent about a dozen from
Irazu. Only one example occurred at Bugaba. ‘The yellow portion of the elytra is,
Mr. Champion informs me, burnished with gold in life, rendering this a very beautiful
and striking object.
2. Epilachna tumida. (Tab. XIII. fig. 2.)
Late subcordata, valde convexa, nigra, haud pubescens, elytrorum disco tumido, gibboso, plaga sanguinea ;
prothorace quam elytra duplo angustiore, his marginibus explanatis, creberrime, ad apicem confluenter
punctatis. Long. 12-13 millim.
Hab. Costa Rica (Van Patten), R. Sucio, Volcan de Irazu (Rogers).
Black, the disk of the elytra raised in a tumid manner, with a deep blood-red broad
stripe on each, leaving the suture narrowly black; the elytral margins expanded and a
little reflexed at the extreme edge, of nearly equal width from the base to the apex, the
widest part a very little below the shoulders.
This insect is not very nearly allied to any Hpilachna yet described ; in colour it is a
little like E. extrema, but the strongly elevated tumid disk of the elytra is unlike any-
thing known to me in this genus, if we except a much smaller very peculiar species
from Ecuador *. Numerous examples were obtained.
* Epilachna pustulifera, n. sp.—Late ovata, nigra, subopaca, tenuiter pubescens; elytris quam prothorax
duplo latioribus, marginibus presertim ad humeros, late expansis, singulis in medio juxta suturam, in
tuberculum corallinum elevatis. Long. 8 millim.
Hab. Cotomsra, Medellin.
This remarkable insect cannot be mistaken for any other yet described. The blood-red tubercles, one on
each elytron near the middle of the suture, take their rise in an oblong spot of the same colour. The general
form is that of the ““Z. proteus” group. It is slightly pubescent.
Two specimens.
2388 COCCINELLID 2.
3. Epilachna plagiata. (Tab. XIII. fig. 3.)
Oblongo-ovata, valde convexa, nigra, nitida, dense brevissime pubescens ; elytrorum marginibus modice expla-
natis, in medio latissimis, disco macula magna transversa plagaque lata versus apicem, juxta suturam
sanguineis ornato. Long. 10 millim.
Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion).
Oblong-ovate, the thorax narrower, but not very strikingly so, than the base of the
elytra, and hence the oval outline is not much interrupted at their junction. The
expanded edge of the elytra is widest in the middle and narrowed towards the base
and the apex. ‘Their disk is extremely closely, finely and evenly punctured, and thickly
clothed with a pubescence that does not prevent their surface shining. The blood-red
patches are very distinctly marked: the basal pair look as if. they would form a fascia,
but are abbreviated externally, and are interrupted at the suture; the posterior pair
are twice as long as wide, rather pointed towards the apex.
4, Epilachna erichsoni.
Epilachna erichsoni, Crotch, Rev. Coccin. p. 58°.
Hab. Panama, Veragua (Mus. Berol.)1.
I have not seen the type of this species. It must be near to the insect here described
as E. plagiata, but the elytra in E. erichsoni are described as being “dark metallic
green,” and the insect from Chiriqui is larger.
B. Elytra ovate, widest a little above the middle.
5. Epilachna olivacea.
Epilachna olivacea, Muls. Spec. Col. Trim. sécur. p. 808°; Crotch, Rev. Coccin. p. 62 (pars) *.
Hab. Mzxico12, Cordova (Hége), Toxpam (Sallé); Guatemata (Sallé), Ostuncalco
7500 feet, Totonicapam 8500 to 10,500 feet, Quiché Mountains 7000 to 8000 feet
(Champion).
We received a series of twenty-five examples from Ostuncalco, showing very little
variation in size and colour; others from Mexico or Guatemala in the Sallé collection
are darker, but of the same form and size. Three of the five examples placed under
E. olivacea in the Cambridge Museum belong to E. obscurella, which appears to me to
be more nearly allied to Z. varivestis, but separable from both it and £. olivacea by the
black legs and trophi.
6. Epilachna picescens.
Oblongo-ovatis, picea, superne nigro-picea; prothorace maculis tribus piceis zgre distinctis; elytroruam mar-
ginibus modice expansis, dilutioribus. Long. 11 millim.
Hab. Panama, Bugaba 800 to 1500 feet (Champion).
Larger, more widely ovate, and with the margins more widely expanded than in
EPILACHNA. 239
£. olivacea, and differing from that species in colour. The upperside is pitchy, with
the head and thorax and the margins of the elytra pitchy-red ; the whole of the under-
side, with the legs, mouth, antenne, and epipleure, is pitchy-red. The thorax has
often three obscure oblong pitchy spots, but often only the middle one is visible. The
punctuation is very fine, but just visible. The suture is paler, and the pubescence has a
plum-bloom appearance. Although allied to E. olivacea and E. tristis, I have little
doubt the five examples captured by Mr. Champion at Bugaba represent a very distinct
species.
7. Kpilachna tristis.
_ Oblonga, subovata, nigra, confertissime minute punctata, pube brevissima cinerea vestita; elytris margine
ampliata, antice latissimis; labro, geniculis tarsisque subtus flavescentibus. Long. 10 millim.
Hab. Mexico, Chiapas (Sallé).
The labrum, base of the palpi, antenne (excepting the club), tips of the femora and
extreme bases of the tibie, and the basal joint and soles of the tarsi in this insect are
rufous, all the other parts being black, with a faintly bluish tint. The most important
distinction between this and #. olivacea, and that which leads me to give it specific
rank, is the widened epipleural margin at the base, the elytra there being twice as
wide as the thorax, thus bringing this species into Section A. It will be seen that in
E. olivacea the thorax is not much narrower than the elytra at their base. And this is
a character on which Mr. Crotch attempted, and I think with some success, to divide
the perplexing forms of EZ. proteus into species. One example only of this insect has
been received; it was labelled E. obscurella in the Sallé collection, which species,
however, it only resembles in having the legs nearly black.

This pretty variety is similar to var.a; but a second vitta, which is only disunited
240 COCCINELLID A.
from the callus by a narrow space, runs into the margin at one-third from the apex,
and emits a ramus from the bend towards the suture.
I have only seen the four examples sent by Becker, of which we figure one.
9, Epilachna vincta. (Tab. XIII. fig. 7.)
Epilachna vincta, Crotch, Rev. Coccin. p. 63°.
Hab. Brivish Honpuras (Blancaneaux); Guatemaa1, Aceituno, Capetillo (Champion) ;
Costa Rica}, San Francisco 4500 feet (Rogers).
Apparently not a common species, only seven examples having been received by us.
10. Epilachna calligrapta. (Tab. XIII. fig. 8.)
Oblongo-ovata, nigra, nitida, vix pubescens; elytris luteis, area basali pone scutellum et supra callum humeralem
ampliata, punctisque quinque in singulis tribus intermediis fasciam obliquam preebentibus, sutura tenuiter
nigris. Long. 7 millim.
Hab. Pawama, Volcan de Chiriqui 4000 to 6000 feet (Champion).
Very like E. vincta, but at once distinguished by the broader and black thorax, the
black body and legs, by the mark on the callus being produced further back, by the
additional spot between this mark and the suture, and by there being only one
subapical spot. ‘Two specimens were obtained by Mr. Champion.
This insect has a very Chrysomeloid appearance, and is suggestive of a species of
Calligrapha.

The Isthmus of Tehuantepec is the southern limit of this species. It is apparently
really distinct from FE. defecta, though hardly differing, except by the presence of a
basal yellow spot on the elytra. The three apical spots are sometimes confluent, but
not so often as in EL. defecta. |
Some very small examples (seven to eight millimetres in length) occurred at
Tacambaro. The legs are generally entirely black.
According to Dugés ®, the insect lives upon Cestrum nocturnum (a Solanaceous plant)
and various Cucurbitacez.

Very abundant from Southern Mexico to Colombia. The variety named fuscipes has
the head and thorax more or less red or yellow, and in these lighter-coloured forms the
body and legs are also red or pitchy-red. Usually EH. defecta has the femora spotted
beneath or entirely pitchy-black, and the tibie and tarsi red. An entirely black variety
occurs with only the tibie and tarsi and tips of the femora, and the mouth and trophi,
orange-yellow. Examples of this form, with intermediate ones having only the two
basal yellow spots, occurred at Tapachula in Chiapas, at Capetillo, and in Costa Rica.
We figure three examples: fig. 9, a fairly typical form from Capetillo; fig. 10, a
variety from Tapa@hula; fig. 11, the var. fuscipes, Muls., from Vera Cruz.
According to Sallé ?, it lives upon Solanum nigrum.

The earlier stages of this insect are described by French (Canad. Ent. 1883,
pp. 189-191), who gives Echinocystis lobata, or common prickly cucumber, as a food-
plant.
According to J. B. Smith, who has described and figured the egg, larva, pupa, and
imago (Ent. News, 1893, pp. 197-199, figg. 1-3), and also the parts of the mouth of
the imago (op. cit. pp. 123-125, fig. 1), H. borealis is steadily becoming more abundant
in the Eastern United States, and has in some localities become a serious pest on
Cucurbitaceous plants of all kinds.
Mr. Champion has also noticed its destructive habits in Central America.

This abundant and very variable species may be easily recognized by its oblong
and not expanded form, and by the number and position of the eight black spots on
each elytron—three basal, one on the callus and two not in line with it and near the
EPILACHNA. 243
suture, three nearly in a straight fasciate line near the middle, and two subapical,
these latter sometimes united and forming an arcuate spot, this constituting the var.
varipes, Muls. This variety is not uncommon; I have seen it from Cordova, Oaxaca,
Capulalpam, the city of Mexico, Chilpancingo, and the Hacienda de Bleados. The
variety named ££. corrupta by Mulsant, and of which the type from Chevrolat’s
collection is before me, is simply a very dark form of this insect with the black spots
represented by denuded spaces, rendering them more distinct than they would other-
wise be; it is scarcely different from the var. MULING,, in which the spot nearest the _
suture of the apical pair is not apparent in the type. An example from Parada in
Sallé’s collection wholly agrees with the form murina, and is labelled “ plumbea, Deyr.”
The soft pubescence in examples of this type is just like that of FE. olivacea and of
E. obscurella, Muls., and it appears probable to me that the latter is only the extreme
form, in which the denuded spots have quite disappeared. We have received a small
series from Oaxaca (/7ége) which appear to be referable to H. murina or HE. corrupta ;
but they are decidedly shorter, and have, consequently, the two subapical spots in a
straight fascia, instead of being obliquely placed. ‘The species disappears towards the
Isthmus of Panama; the only two specimens obtained there by Mr. Champion are of
the yellow form, in one of which the basal row of spots is gone, in the other they
re almost obsolete. £. simillima, Crotch, from Bogota, is, I think, rather a form of
#. borealis than, as he thought, of this insect.
Dr. Palmer has sent the larva (fig. 20) and pupa of a pallid variety of E. varivestis
from Mexico city. The larva is clothed with branched and variegated black-and-white
spines. The pupa retains the larval skin, only partially cast, on its hind body. There
is a record of E. corrupta from New Mexico (cf. ‘ Insect Life,’ ii. pp. 113, 114 (1889)].
We figure a typical example from Oaxaca (fig. 17); the var. varipes, Muls., from
Cordova (fig. 18); and a pale variety (fig. 19) and its larva (fig. 20) from Mexico city.
15. Epilachna obscurella.
Epilachna obscurella, Muls. Spec. Col. Trim. sécur. p. 809 ‘
Hab. Mexico } (Saillé), near the city (Hége).
The smaller size, more oblong shape, and black legs and trophi seem to be sufficient
to give this form specific rank. ‘The elytral margins, moreover, are hardly expanded.
It is, however, very difficult to distinguish this from nearly black forms of £. varivestis.
Crotch (Rev. Coccin. p. 62) treats E. obscurella as a variety of E. olivacea.
16. Epilachna vulnerata. (Tab. XIII. fig. 21.)

We have a specimen of this insect from Sallé’s collection, and there is another in
the Cambridge collection which Crotch placed with E. aubai, and is apparently one
of the examples he alludes to under that species, when he says “‘in mature specimens
the elytra have a dark central fascia.” The insect before us is, however, broader
and differently coloured, and does not look at all like a variety of £. aubai. The
elytra have their margins very narrowly reflexed; they are nearly as broad as long,
clothed with a very fine downy pubescence; the basal fascia occupies the callus, and
thins off and becomes indistinct towards the scutellum ; the central fascia is only very
narrowly interrupted at the suture. The underside, coxe, and femora are black, the
tips of the latter, the tibie, and tarsi being orange-red.

I cannot identify any examples I have seen with this species. Although the type
would seem to have passed into Crotch’s collection, it is not to be found there, nor
does the name stand there now. He remarks of it, “ Very close to E. aubei, but
differs by having the coarse punctures apparent.”
19. Epilachna vanpatteni. (Tab. XIII. fig. 22.)

The single example from Costa Rica cannot be assigned to any species known to me,
and is well and definitely marked. The specimen from the Volcan de Atitlan is more
pubescent, and has all the marks cloudy and ill-defined; it might have been mistaken
for £. borealis, but the fascia following the three basal spots, and the three subapical
spots following the three postmedian ones, differentiate L. vanpattent from that species.

(H. H. Smith); Guatemata, San Gerénimo, San Joaquin, Chiacam, Cubilguitz, San
Juan, and La Tinta, all in Vera Paz (Champion).
Subject to a good deal of variation, both in size and colour. The examples from
Oaxaca agree precisely with the type, which is before me (mus. Crotch, Cambridge,
ex Chevrolat). These have a heavy pubescence, a completed dark submarginal zone,
and the suture dark, but shining in the middle, and are very similar to Ladoria delphine.
Most of the examples from Vera Paz are smaller and darker, with the thorax dark on
the disk, the zone often interrupted near the apex, &c. The South-American J. cir-
cumflua, Muls., scarcely differs from this, and is regarded by Crotch as synonymous
with E. contempta, Muls., from Buenos Ayres. We have received a large series of
examples. A specimen from Toxpam is figured.
24, Epilachna inepta.
Orbiculis, parum convexa, pubescens, sordide ochracea; prothorace elytrorumque lateribus dilutioribus, his
zonula submarginali pone medium abbreviata punctoque discoidali, illo punctis duobus basalibus haud
bene discretis fuscis. Long. 4°5-5 millim.
Hab. Mexico, Presidio (Forrer), Playa Vicente (Sal/é).
246 | COCCINELLIDZ.
The sordid yellow colour and ill-defined black markings of the three examples before
me may be due to their slight immaturity, and the certainly deep and broken style of
punctuation in the two from Presidio is perhaps partly due to the same cause; the
black dot on the disk of the elytra is, however, a distinctive character, which prevents
my referring this insect to E. circumflua (a South-American species) or any of its close |
allies. It is, of course, possibly a form of #. métis, and can at present only be regarded
as a tentative species. It seems probable, however, that there are many closely allied,
small, zonate species of Epilachna.
_ 25, Epilachna virgata.
Epilachna virgata, Muls. Spec. Col. Trim. sécur. p. 855+; Crotch, Rev. Coccin. p. 67°.

2000 to 3000 feet, Caldera (Champion).—Sovuta America, Colombia!, Venezuela ?,
Andes above 9000 feet 2.
The elytra have two dark stripes, besides the zone near the margin, and, as Crotch
remarks ?, “ the striped appearance due to the arrangement of the pubescence is very
characteristic.” Some examples from the Volcan de Chiriqui are very dark and suffused,
so that the vitte and zone are not conspicuous. Fifteen examples were sent by
Mr. Champion.
SUPPLEMENT.
Tue following notes and descriptions refer to insects which have been sent us during
the publication of this volume; in a few cases to others which had been reserved for
further examination as being of doubtful location.
ACROPTEROXYS (p. 18).
Acropteroxys caudata (p. 13).
To the Mexican locality given, add :—Chilpancingo in Guerrero (H. H. Smith).
3. Acropteroxys acuminatus.
Niger, capite prothoraceque parce punctatis, hoc oblongo, lateribus distincte marginatis ; elytris apicem versus
acuminatis, apicibus divaricatis, leviter striato-punctatis, interstitiis punctulatis ; antennarum clava sex-
articula. Long. 75-8 millim.
Hab. Mexico, Chilpancingo and Omilteme in Guerrero, 4600 to 8000 feet
(H. H. Smith).
Head, thorax, and antenne black, the head and thorax deeply and rather sparsely
punctured. The antenne have the first four joints short, and scarcely longer than
wide ; the fifth joint is a little widened ; the sixth to the eleventh form along and
lax club. The prosternum is transversely wrinkled, and impressed with scattered
coarse punctures, its process widened towards the tip and much depressed. ‘The
metasternum is smooth, with a few dispersed small punctures. The prothorax is
oblong, but not so long asin A. gracilis; its sides are sinuate, and its front angles more
depressed than in that species, and it hence appears more cylindrical. The elytra are
a little tumid near the base, and taper from thence to the apex, where they are slightly
divaricating ; they are also minutely denticulate, but the denticulation is only visible
under a very strong lens.
This insect, of which only two specimens were obtained by Mr. Smith, diverges a
little from the type of the genus in which I place it, inasmuch as the antenne have
the last six joints nearly equally wide and the fifth joint also widened a little, so that
the club is very gradually formed. In the punctuation and colour it is very like
Ortholanguria elongata, but the general shape is more acuminate.
248 SUPPLEMENT.
DASYDACTYLUS (p. 14).
Dasydactylus buprestoides (p. 15).
To the locality given, add :—Gvatemata, Coban in Vera Paz (Conradt).
2(a). Dasydactylus zneopiceus.
‘/Eneo-piceus, elytris viridi-nitentibus, antennis tarsisque nigrescentibus; capite prothoraceque fere glabris,
hoe subquadrato, femine minute punctulato; elytris obsoletius punctato-striatis, interstitiis postice
punctatis, Long. 11-13 millim. ¢ 9°.
Mas, prothorace convexiore, lateribus antice magis rotundatis, tarsis anticis dilatatis fulvo-hirtulis.
Hab. Mexico, Teapa in Tabasco (H. H. Smith).
This species is very closely allied to D. subulatus. It differs principally in the
pitchy-red colour of the head and thorax, and in the latter being shorter and relatively
broader in both sexes than in that insect; the elytra are at the same time broader and
less subulate. D. wneopiceus is also clearly allied to D. glabricollis, but appears to be
a more robust insect and is differently coloured.
Dasydactylus picipes (p. 22).
To the localities given, add :—MeExico, Teapa i in Tabasco (H. H. Smith).
Dasydactylus sellatus (p. 23).
To the Mexican localities given, add :—Temax in N. Yucatan (Gawimer).
Among many examples of this species sent from Teapa by Mr. H. H. Smith (whence
I have already recorded it) are several of the variety with the head black.
CROTCHIA (p. 28).
Crotchia parvula (p. 32).
To the localities given, add :—Mexico, Teapa in Tabasco (H. H. Smith).
THALLISELLA (to follow the genus Crotchia, p. 32).
Thallisella, Crotch, Cist. Ent. i. p. 402 (1876).
This genus, of which the type is 7’. peruviana, Crotch, is clearly a member of the
Erotylide and has undoubted affinity with certain members of the Languriide. It is
well and sufficiently characterized by Crotch, with the exception of the male characters
observable in the Central-American species; but with singular inconsistency he has
included in it a second species from a wholly different part of the world—TZ. malasie,
which is not congeneric. ‘This latter is, in fact, a member of the genus which has
subsequently been described by Mr. Fowler under the name Paracladoxena.
The TZhalliselle are small Triplacid-looking beetles, with coarsely granulated,
prominent eyes; very broad tarsi, with spongiose soles, apparently four-jointed, but
EROTYLIDA. 249
really five-jointed, the claw-joint having the basal node; distinct metasternal and
abdominal lines or carine; and stout antenne, with a three-jointed club. The elytra
are faintly striated below the shoulders.
We have two species to record from Central America.
The toothed intermediate femora in the male of 7. crotchi are very remarkable,
and the three ventral segments having each a pilose dot in the same sex are quite
analogous to the character figured for Crotchia proxima (cf. Tab. I. fig. 24 a). I cannot
say whether these characters exist in the male of 7. peruviana, Crotch.
1. Thallisella crotchi.
Oblonga, parum ovata, ferruginea, nitida; thorace transverso-quadrato, parce punctulato, basi bifoveolato ;
elytris punctato-striatis ; antennarum articulis quatuor ultimis clavam formantibus, nigris.
Mas, femoribus intermediis late dentatis, abdominis segmentis secundo, tertio et quarto, puncto piloso. Long.
42 millim.
Hab. British Honpuras, Belize (Blancaneaur); Panama, Bugaba, Volcan de
Chiriqui (Champion).
This species is deep rusty-red in colour, with the punctures in the striz fuscous, but
only faintly so beneath the surface ; the strize are about eight in number, but towards
the side become short and confused ; the marginal stria is deep and sinuous, and the
margin much inflexed. The thorax is transverse, but not twice as wide as long; the
front angles are deflexed and acute, and the hinder angles also rather acute, the sides
being slightly sinuate ; upon the disc there is an irregular and indistinct M-like fuscous
mark. These fuscous markings, as well as those in the strie, are not always present.
The underside is smooth and shining, with a few scattered punctures upon the meta-
sternum. The prosternal process is raised at the sides, and has a rather obsolete carina
in the middle.
Three examples from the Volcan de Chiriqui, which appear to be females, have
the apical joint of their antenne red, and the elytra rather more infuscate in the
middle than in the Bugaba specimens, with the base, shoulders, and apex lighter
ferruginous-red.
2. Thallisella conradti.
Oblongo-elongata, nigra, nitida; antennis, pedibus elytrisque ad apicem picescentibus ; capite crebre fortiter
punctato, fronte late subbiimpressa; antennis capitis thoracisque longitudine, articulis secundo ad
octavum subsqualibus, gradatim brevioribus, haud elongatis, clava haud abrupta; prothorace transverso-
quadrato, crebre ac distincte punctulato, basi profunde bifoveolato ; elytris sat profunde striato-punctatis,
interstitiis planis, glabris. Long. 44-5 millim.
Hab. Guatumata, Coban in Vera Paz (Conrad).
If this insect had come from the eastern hemisphere, I should have unhesitatingly
placed it in the genus Thallis. The five-jointed tarsi (the claw-joint having a distinct
but small node at its base) will easily prevent its being confused with any species of
BIOL. CENTR.-AMER., Coleopt., Vol. VII., December 1898. 2 Kk*
250 SUPPLEMENT.
Hapalips, no less than the total absence of pubescence and the presence of basal sulci
on the thorax; the latter are very short, but deeply impressed, and connected by a
transverse impression, the sides and base of the thorax being margined. The thorax
is one-fourth wider than long, rather sparsely but distinctly punctured, the width in
front scarcely less than at the base, but the front angles are a little deflexed. The
elytra are very distinctly punctate-striate, there being about eight strize on each, that
nearest the suture at the base being punctured for a short distance only, and then
merging in the unpunctured sutural stria; near the apex all the strie become obsolete.
The scutellum is transverse. The legs are pitchy; the tibie are simple, a little
widened at the tip in the front pair. The eyes are more coarsely faceted than in
Hapalips.
Two examples.
HAPALIPS (to follow the genus Thalliselia).
Hapalips, Reitter, Verh. Ver. Briinn, xv. Abhandl. p. 122 (1877).
This genus was formerly placed by its 4uthor in the Rhizophagide. He has,
however, himself noticed the analogy of the tarsal structure with that of Languria,
and Mons. A. Grouvelle, in rejecting them from the association named, considers them
better placed with the Languriides. Their general structure—that of the head, the
antenne, the prosternum, and occasionally visible, though very obsolete, ‘* abdominal
lines,’—apart from the form of the tarsi, fully bears out this conclusion.
Reitter enumerated ten species, all with one exception from the Southern continent
of America. Specimens of two species have been lately sent by Mr. H. H. Smith from
St. Vincent and Grenada, in the West Indies. We here enumerate five, chiefly
from Mexico. ‘They are therefore rather widely distributed *.
A. Interstices of the elytra not punctured.
1. Hapalips cribricollis.
Oblongus, subparallelus, leviter convexus, nitidus, rufo-piceus, parce pubescens; capite prothoraceque parce
fortiter punctatis, elytris fortiter punctato-striatis, fronte obsolete biimpressa; prothorace quadrato,
lateribus tenuiter marginatis, ante basin obsolete bifoveato ; elytris prothorace paullo latioribus, interstitiis
levibus ; antennarum articulis quarto ad octavum subquadratis, clava abrupta; capite, prothorace
elytrorumque fascia sat lata, pone medium sita, sepe saturatioribus. Long. 3°75-4 millim.
Hab. Mexico, Motzorongo in Vera Cruz (Flohr), Teapa in Tabasco (Hége).
This species appears to me to be rather near H. gracilicornis, Reitter, and to differ
from it in being more shining, with the head and thorax more sparsely and more
deeply punctured. ‘The antenne are as long as in that insect, but have the intermediate

and Panama: these, unfortunately, cannot now be found.
EROTYLIDA. 251
Joints bead-shaped, with the club more abrupt. The front angles of the thorax are
subdentate a little below the actual angle, nearly as shown in figure 2 of the plate
accompanying Reitter’s descriptions. The head is distinctly bifoveolate, but the fovee
are small and not deep. In the majority (five out of eight) of the specimens sent the
head and thorax are dark pitchy-red, and the elytra have an ill-defined rather curved
fascia, and a very indistinct spot near the scutellum, darker than the ground-colour.
2. Hapalips filum.
_ Hapailips filum, Reitter, Verh. Ver. Briinn, Abhandl. xv. p. 125°; Gorham, P. Z.S. 1898, p. 335 *,
Hab. Mexico, Frontera in Tabasco (Hége).—Cotompta!; ANTILLES, Grenada ®.
I refer a single example sent by Hoge from Tabasco to this species.
B. Interstices of the elytra punctured.
3. Hapalips reitteri.
Elongato-oblengus, nitidulus, capite prothoraceque parcius, elytris densius pubescens, fuscus vel obscure
ferrugineus; capite inter oculos transversim late biimpresso; antennis capite prothoraceque sesqui
brevioribus, articulis quarto ad octavum nodiformibus, clava abrupta; prothorace quadrato, cum capite
parcius distincte punctato, lateribus tenuiter reflexo marginatis haud crenulatis, disco squali, basi
obsolete biimpresso ; elytris perobsolete punctato-sulcatis, interdum punctato-striatis, interstitiis seriatim
confuse punctatis. Long. 5°5-6 millim.
Hab. Mexico, Jalcomulco in Vera Cruz (Flohr), Vera Cruz (Sallé).
This species by its large size seems distinct from any yet described, except /. grandis,
_ Reitter, from Colombia, from which the punctuation of the interstices of the elytra
separatesit. The eyes are large and prominent, but the head is narrower by one-quarter
than the thorax. The latter is nearly square, not wider than long; the front angles of
the reflexed margins are not so far advanced as the front margin, looking as though
they were excised below the eyes; its surface is covered with distinct, somewhat
stellate, flat-bottomed punctures, which here and there are confluent. The elytra have
the rows of punctures irregular, often confluent, while the punctures of the interstices
are scarcely smaller, but less confused than those of the strie; near the scutellum,
however, and for some way along the suture, they are quite confused with those of the
strie. The general colour is obscurely ferruginous, the elytra often becoming nearly
fuscous with lighter shoulders. The pubescence in this insect (as in the other species
here described) is golden and serially arranged. ‘The metasternal and abdominal lines
are in the form of very fine raised carine and are very short. |
I refer seven examples to this species, all of which are from the Sallé collection, with
the exception of the one from Jalcomulco.
4. Hapalips flohri.
Oblongo-elongatus, nitidulus, parce pubescens, piceus, capite prothoraceque crebre distincte ac profunde
punctatis ; elytris punctato-striatis, interstitiis evidenter seriatim punctatis ; fronte utrinque late obsolete

252 SUPPLEMENT.
- biimpresea; prothorace oblongo-quadrato, angulis anticis integris, rectis, lateribus et basi tenuiter
marginatis, hoc obsolete bifoveolato; antennis brevibus, articulis quarto ad octavum nodiformibus,
Long. 6 millim.
Hab. Mexico, Motzorongo in Vera Cruz (Flohr).
Equal in size to H. reitteri, but at once separable from it by the more shining, less
pubescent surface, the longer thorax, which is a little longer than wide, with the anterior
angles in a line with the front margin, and the distinctly punctate-striate elytra; the
punctures on the latter are not in irregular rows, although they are very close and in
places, especially externally, become confluent. The rows of elongate punctures on the
elytral interstices are also more regular and more distinct than they are in H. reitteri.
The colour is uniformly pitchy.
One specimen only has been received of this insect, and it is possible that the
pubescence has been partly rubbed off; but even if this is the case the surface is less
alutaceous, and the puncturing is stronger and more regular, than that of H. rettteri.
5. Hapalips parallelus.
Oblongo-elongatus, parallelus, breviter pubescens, fuscus, infra cum pedibus ferrugineus; capite crebre minute
punctato, fronte obsoletius biimpressa ; antennis breviusculis, ferrugineis, articulis quarto ad octavum
transversis, clava abrupta; prothorace transverso quadrato, parcius haud profunde punctato, basi utrinque
subimpresso, lateribus tenuiter marginatis ; elytris thorace parum latioribus, lateribus parallelis, obsolete
striato-punctatis, interstitiis minute seriatim punctatis. Long. 4 millim.
Hab. Mexico, Vera Cruz (Sallé), Frontera in Tabasco (Hége).
Var. Obscure ferrugineus,
Hab. Muxtico, Colima city (Hége), Vera Cruz (Sallé).
Apparently very near H. fuscus, Reitter, from Brazil. The punctures of the inter.
stitial series of the elytra seem to be finer than they are in that insect, to judge from
the description, indeed they are so fine as not to be easily seen. The punctures of the
striee are very numerous, oblong, and almost confluent; those of the thorax are stellate
and flat-bottomed. The abdominal lines are fine, carinate, extending over two-thirds
of the basal segment.
Seven examples,
EUXESTUS (to precede the genus Megalodacne, p. 33).
Euxestus, Wollaston, Ann. & Mag. Nat. Hist. (3) ii. p. 411 (1858) ; Lacordaire, Gen. Col. xii.
p. 26; Gorham, P. Z. 8. 1898, p. 336.
Eusestus is a genus formed by Wollaston for a very small insect somewhat resembling
a small pitchy-coloured Dacne, from Madeira. It is apparently rather closely allied to
Eastern insects of the genus Tritomidea, Motschulsky ; but the New World species
differs from them in the structure of the antenne and in other points which I have
already noticed elsewhere.

A single example, apparently belonging to this species, but differing as above. The
four thoracic spots are equidistant, in a transverse row, and show no tendency to unite,
as in the type. The black markings of the elytra are more diffused, so that the two
basal spots described in the type are here quite united, and the suture is black between

Antenne rather long, and the club lax for this genus. Thorax with the sides nearly
straight, only a little contracted to the front angles, transverse; front scarcely excised,
the angles acute, the base sinuate. Elytra and scutellum black, the former deeply
punctate-striate, with the interstices not quite smooth. The legs are blackish in one
example, but the tarsi even in this are red. The meso- and metasterna and the
abdomen are black, and are strongly punctured, the latter being smoother in the
middle. |
Two examples.

Gén. Col. xii. p. 53 (1876) ; Crotch, Cist. Ent. 1. p. 483.
A genus of about twenty species, all hitherto described being from the southern
continent. It has very much the form of Mgithus, but is distinguished from that
genus by the coarsely granulated eyes, as well as by the outline not being so uniform,
the thorax having its sides more rounded and its base more rectangular than is usual
in Atgithus.
1. Cyclomorphus sordidus.
Valde convexus, gibbosus, fere glaber, sordide luteus, subtus piceo-variegatus ; ore, antennis, palpis pedibusque
nigris, femoribus infra luteo-pictis; elytris nigro-piceis, sutura marginibusque indistincte luteis. Long.
9 millim.
Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith).
Broadly ovate, the apex of the elytra very declivous and pointed; impunctate, but
with a fine alutaceous sculpture, which renders the surface not very brilliant, though
shining. Head and thorax luteous; the mouth, antenne and palpi, and the extreme
margins of the thorax, are black. Thorax with the base more than twice as wide as
the length, the front not deeply excavated. The antenne are rather longer than the
head and thorax together. The scutellum is black. The elytra are smooth, but not
EROTYLIDA, 258
very shining nor so clearly alutaceous as is the thorax; the suture and margins are
bordered by a very fine impressed line close to their edge, the former is depressed, and
the latter are not at all expanded. ‘The under surface is impunctate, and there are no
coxal lines. The prosternum is simple, 7. ¢. not carinate nor elevated in front.
The discovery of a species of Cyclomorphus so far north, and at such an elevation, is
interesting, as the genus has not, so far as [ am aware, been recorded previously from
the northern continent.
ZEGITHUS (p. 85).
Aigithus uva (p. 88).
To the localities given, add :—Muexico, Teapa in Tabasco (H. H. Smith).
One small example, apparently referable to this species.
PLASTOCOCCUS (to follow the genus Ayithus, p. 92).
Corpus suborbiculare, gibboso-convexum, coccinelliforme. Pronotum perbreve, valde arcuatum; prosternum
equale, haud carinatum; metasternum lineis coxalibus integris elevatis. Elytrorum marginibus modice
explanatis, epipleuris declivis. Caput in prothorace receptum, oculis leviter granulatis ; antenne breves,
clava laxe formata quadriarticulata, haud multo incrassata; palpi labiales articulo ultimo valde securi-
formi.
The above name is proposed for a very Coccinellid-looking species of Erotylide,
which with no very decided characters is yet not to be associated with any described
genus. It is perhaps most nearly allied to Coccimorphus and Aigithus.
1. Plastococcus atricinctus.
Rufo-ferrugineus, supra sanguineus, capite, prothorace (basi excepta) elytrorumque marginibus late, ad apicem
latiore, nigris; elytris vage seriatim punctatis, interstitiis disperse punctulatis. Long. 33-4 millim.
Hab. Panama, Bugaba, David, Volcan de Chiriqui 4000-5000 feet (Champion).
The disc of the elytra, the scutellum, and the extreme base of the thorax are
blood-red; the head and rest of the thorax are black and smooth; the thorax is short
and arcuate, formed exactly as in Chilocorus. The antenne are shorter than the head
and thorax together; they are obscurely yellow, with a blackish club. The palpi
externally are dark. ‘The front and sides of the thorax are margined by a very fine
line; the base is not margined. The elytra are oval and slightly cordate, smooth and
shining, with seven or eight series of distinct punctures, and with confused punctures on
the sides and at the apex. The underside and legs are entirely rich tawny-ferruginous,
and the true epipleural fold of the elytra is of the same colour, the strongly inclined outer
margin being black. The whole form of this insect, and its colour, is so remarkably
like that of a Chilocorus that, but for the stouter and apparently four-jointed tarsi, the
somewhat stouter antenne, the absence of abdominal coxal fossettes, and the serially
punctate elytra, it might readily be taken for a member of that genus.
A considerable series of specimens was obtained by Mr. Champion.
256 SUPPLEMENT.
2. Plastococcus apicalis.
Sanguineo-rufus, capitis basi prothoraceque (basi et lateribus exceptis) indeterminate nigris ; elytris singulis
macula subapicali nigris, vix punctulatis. Long. 5 millim.
Had. Panama, San Feliz in Chiriqui (Champion).
Larger than P. atricinctus. The mouth, antenne, palpi, and the base and sides of
the thorax are yellowish-red, but in a vague way, and are evidently variable in the
degree to which this colour extends. The elytra are more obsoletely punctulate
(in one example nearly smooth); they are entirely blood-red, except the two spots
near, but not quite reaching, the apex, which together form an arcuate mark nearly
disjoined at the suture.
P. apicalis is evidently very nearly allied to, and perhaps only a local variety of,
P. atricinctus. |

The above is the formula (so far as I have examined the two specimens) for a very
small beetle of doubtful location, at first sight resembling a small Cercyon, but
apparently allied to Dacne, and perhaps to Xestus of Wollaston; but differing in the

the Erotylide and in the Endomychide, with the tarsi apparently four-jointed and very
simple, 7. ¢. neither expanded nor with bilobed joints. That these insects are of doubtful
location in the Clavicorn series is obvious, when it is considered that the relation
of many genera with such families as the Cryptophagide and with genera such as
Ephistemus is not well ascertained. |
1. Brachylon breve.
Oblongo-ovatum, nigro-piceum, nitidum; antennis pedibusque flavis; elytris singulis seriebus quinque

Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith); Nicaracua, Chontales
(Janson).
Broadly-oval, pitchy-black, the head, thorax, and the base and margins of the elytra
being of a pitchy-red, almost blood-red colour ; the antenna, palpi, and legs are chestnut-
yellow. The whole insect is smooth and shining, without pubescence, and impunctate
(saving about seven series of rather sparsely disposed punctures on the elytra, which
terminate at about one-third from the apex). The head is small, received, but not
deeply, into the thorax, and when turned downwards forming a uniform outline with
its front. The antenne are short, with a capitulate club, apparently consisting of three
closely soldered joints. The eyes are small and very slightly prominent. The palpi are
very little developed, and cannot easily be observed ; they are light yellow, and appear
to have a small securiform apical joint. The thorax (with the head) is quite smooth ;
its sides are very finely margined; the front angles are depressed, so that the small
opening for the head is not much cut out, but would appear semicircular viewed from
the front. The elytra are of the same width as the thorax at the base, and closely fitted
to its bisinuate hind margin; they are smooth. with the exception of the punctate
strie. In some examples the whole insect is nearly black, with yellow legs and
trophi. .
Five examples, all apparently referable to one species.

the Endomychide, but it must be admitted it has less claim than the other genera
toa place there. The tarsi are simply four-jointed, but the remarkable insects. which
compose this genus have neither the general appearance nor structure of the family.
They present rather the suggestion of an abnormal form of Cryptophagide, and have a
certain relationship to the European genus Pleganophorus, now usually placed among
the Colydiide. |
The distribution of the five species recorded is no less remarkable: one from
Madagascar ; one widely spread in the East (Burma, the Philippine Is., Java, the
Nicobar Is., &c.); one from Burma; one obtained from gum-copal; and one from
Tropical America. ) .

Antonio near Bogota +, Tolima 3.
Of this curious insect a male and two female examples were found by Mr. Champion
in Chiriqui. The females have one more joint in the funicular portion of the antenne
than the male, and the apical joint is much less massive and more pubescent. The
colour in our examples is uniformly fulvous. The insect appears to be found under
the bark of decaying trees.
CRYPTOGNATHA (p. 181).
Cryptognatha auriculata (p. 182).
To the localities given, add :—GuaTEMALA, Panzos and San Gerdnimo in Vera Paz
(Champion); Panama, Bugaba, David, Caldera, Volcan de Chiriqui (Champion).
About a dozen specimens from Panama are, I think, to be referred to this species.
They are nearly unicolorous, the head and front angles of the thorax being paler in
some specimens, which may be the males, and the legs are paler yellow than the upper
surface. ‘The elytra have the juxta-sutural row of subcutaneous fuscous dots often
present, and continued parallel to the base; the punctures are very faintly and
obsoletely serial near the margin, in an extremely shallow sulcus. The front tibie, in
what I suppose to be the male, have their outer edge compressed, so as to appear to
have a membranous projection, widest near their base, and the middle and hind tibie
are emarginate on their outer sides. Single examples from Teapa and Panzos
respectively are evidently males, and have the head wide and concave, and the thorax
with the front margin as well as the sides white.
Mr. H. H. Smith has met with the species at Teapa, whence I have already
recorded it.

Mas? capite (basi excepta) luteo.
Hab. Panama, Volcan de Chiriqui (Champion).
- Orbiculate, and nearly hemispherical, very shining; the body beneath, the head
(excepting at the base), the deflexed angles of the thorax, and the legs yellow. The
tibie are obliquely cut off for the reception of the tarsi, and are not toothed or angular,
and scarcely project at the angle formed by the truncation externally. The mouth is
yellow, the trophi very short (not observed). The thorax is very distinctly and thickly
punctured, black, with a brassy tint, its base with a fine marginal line ; the angles in
one example very narrowly blood-red, in the other (perhaps the male) widely luteous.
In this last-mentioned example the head is luteous, and the base has the black part
as a double spot, whereas in the other example (the possible female) it is blood-red,
with the basal half black. The elytra are convex, distinctly punctured ; the disc is of
a fine deep chestnut or blood-red, this colour reaching the base ; from the basal angles
runs a broad black band along the margin, but leaving it at halfway, the two bands joined
at the suture, and leaving the apical margin red. ‘There is in the female (?) example
a row of subcutaneous fuscous-black dots parallel to the suture, but the true punc-
tuation is nowhere serial; it is also very evenly distributed, being a little closer near
the apex of the elytra.
Two examples.
1 (3). Cryptognatha amicta.
Corpus cum pedibus caputque (prothoracis margine antico et lateribus late concoloribus) albido-flava ;

Hab. PanaMa, Bugaba (Champion).
Very similar to C. annulata, but more widely orbiculate ; the thorax wider and its
sides more uniformly in outline with the elytra, forming an almost perfect circle.
The punctuation (especially that of the thorax) is much finer. The head is whitish-
yellow, hollowed out in front, wide, the outer angles of the clypeus turning outwards.
The thorax has the front margin and sides widely whitish, the black portion of
the base not reaching nearer than a quarter of its width from the hind angles, and
therefore, though completing the black ring, not being as wide nor quite continuous
with it. The scutellum is red, whereas in C. annulata it is black. The front tibie
are outwardly widened and compressed, especially near their base.
Two specimens, both males.

Hab. Panama, Volcan de Chiriqui, Caldera (Champion).
This species has the punctuation fine and close, but quite distinct, becoming
subseriate under the callus, where it is also coarser; the whole form is rather
oblong than orbiculate, and it is as usual very convex and shining. One of the two
examples has the mouth rather more pitchy than in the other, and also the extreme
edge of the middle of the front margin of the thorax pitchy; but I think both are
females, and I should expect the male to have a red head. The thorax is entirely
black, excepting as mentioned; its base is very finely margined. The scutellum
appears to be black, but becomes at least pitchy in one specimen. The black apex of
the elytra is almost divided by the red being produced along the suture.
Two examples.

Hab. Guaremaua, Senahu in Vera Paz (Champion).
This little species is smaller than C. ¢erminata, but is very like it. It differs,
however, in having the apex of the elytra black. The scutellum is yellow. The
suture itself appears a little darker than the elytra, which are otherwise of a bright
chestnut-yellow.
A single specimen, probably a female.

Hab. GuatemMaia, San Joaquin in Vera Paz (Champion).
This insect is widely orbiculate in form and very convex, and has the punctuation
very fine. The head in the example from San Joaquin is whitish, rather concave, and
with the outer angles of the clypeus sharp and projecting, indicating the male sex.
One of the other two specimens, that from San Gerdnimo, has the head dark red, and
it is probably a female, the tibie in this example being feebly developed. One
specimen from each locality.
Obs.—This insect is allied to a species of Cryptognatha (C. amabilis, Gorh.) from
Brazil, of which a description is given below *.

Hab. Guatemata, San Gerénimo, Panzos, San Juan and Tamahu in Vera Paz,
Capetillo (Champion).
The general colour of this rather obscure insect is luteous-yellow, but the head and
thorax are often whitish, yet with darker shades which sometimes appear as three
spots on the thorax. The whole breast is black, but the legs, including the coxe and
trochanters, are entirely pale yellow. The punctuation of the head and thorax is very
fine, scarcely visible under a Coddington-lens ; that of the elytra is fine, but more
distinct.
The examples from San Juan, Tamahu, and Capetillo have the breast concolorous or
very slightly darkened, but without knowing more of the habits of the living insect
* Cryptognatha amabilis.

Both this species and C. amabilis are distinguished by the strongly deflexed basal margins of their elytra
and (accordingly) rounded base of the thorax, which viewed from the front is Q-shaped, reminding one of a
small Chilocorus, and by the orbiculate elytra with slightly expanded margins,

I do not feel that it is possible to determine whether more than one species is
represented. :
The description is taken from specimens from San Gerénimo.

PORIA (p. 207).
6 (a). Poria stellaris.
Orbicularis, haud valde convexa, nigra, nitida; elytris ad humeros submetallicis, crebre irregulariter stellato-
punctatis ; capite, prothorace (basi excepta), abdomine pedibusque pallide testaceis. Long. 5 millim. g.
Hab. Panama, Bugaba (Champion).
Antenne very short for this genus; head and palpi pale whitish-yellow; thorax
smooth and shining, with very fine and thin pubescence, the base black, with two
punctiform projections almost detached in the middle, the whole front and sides,
including the hind angles, pale yellow, the front angles very little produced. The
tibie are very clearly excavated externally below the middle for the tarsi to lie back
upon, but are rather flattened than grooved. The length of the legs, the irregular but
strong punctuation, which is of the stellate or broken kind, and the sinuation of the
epipleural margin, will prevent this insect being taken for a Ladoria. One example,
apparently a male. .
ZENORIA (to precede the genus Weaporia, p. 217).
Zenoria, Mulsant, Spec. Col. Trim. sécur. p. 898 (1850) ; Crotch, Rev. Coccin. p. 277.
Zenoria is a genus consisting of four or five South-American species, with which the
insect we place here agrees rather closely ; the coxal fossz do not, however, cover more
than half the segment. The tibie are all received very deeply into grooves of the
femora, so as to be almost concealed, and they are strongly narrowed towards their
apices.
1. Zenoria circumclusa.
Orbicularis, subcordata, parce breviter pubescens, castanea vel sanguinea, subtiliter creberrime punctata ;
prothoracis macula basali cum zonula elytrorum lata fere in medium disci, ad apicem exeunte, annulum
prebente. Long. 4 millim.
Hab. Panama, Volcan de Chiriqui, David (Champion).
COCCINELLID. 263
This species is very like some of the small zonate Epilachne, especially FE. circum-
ducta; but it will hardly be confused with any of these, if the compressed femora,
with the flat tibie fitting into grooves in them, the very short tarsi, and the deflexed
vertical head, with the mouth hidden below, are noticed. The black zone, with the
black base of the thorax, forms a nearly complete ring, but runs out to a point at the
suture; it is further removed from the margin than in the Epilachne most like it,
and in this respect the present species resembles Z. revestita, according to two
specimens in Crotch’s collection, but it does not appear that these agree with Mulsant’s
description, in which no mention is made of a pale disc of the elytra.
The brevity of the coxal fosse might seem to remove this insect from the genus;
but the fact is that it is allied to Z. subcostalis, and I do not see any reason why
Z. revestita should be taken as the type of the genus.
CINACHYRA (to follow the genus Neaporia, p. 224).
Caput latum, in prothorace bene receptum, oculis magnis. Prothorax squalis, opacus, angulis anticis
subacutis, margine antico pone oculos sinuato. LElytra breviter oblongo-ovata, apice late rotundato,
creberrime longitudinaliter rugosa. Tibie simplices, tarsi validi, tibiarum dimidium longitudine
superantes.
The very curious insect for which we are obliged to propose a new generic name is
at present only doubtfully associated with the Ortaliides, chiefly on account of its wide
head and vertically ovate eyes.
The rngose sculpture of the elytra and of the breast and the style of coloration are
quite unusual in the Coccinellide.
1. Cinachyra picta.
Nigra, opaca, capite prothoraceque subtilissime punctatis, elytris creberrime rugosis, quasi alutaceis, episto-
matis punctis duobus; prothoracis angulis anticis tenuissime marginatis, et punctis duobus minutis;
elytrorum macula discoidali utrinque hamata punctisque nonnullis perminutis, duobus basalibus, duobus
apicalibus, alterisque discoidalibus lete aurantiacis ; pedibus piceis. Long. 2 millim.
Hab. Mexico, Chilpancingo in Guerrero (ZH. H. Smith).
Head opaque, with two orange dots on the epistome. The thorax is opaque, wide,
with the sides nearly straight, the base much rounded, and the front angles prominent ;
the post-ocular sinuation of the front margin is rather deep; there are two minute
orange dots on the posterior part of the disc. The elytra are intricately wrinkled in a
longitudinal direction, the rugee quite close and very minute ; on each elytron there is
an orange mark, almost, joined to the opposite one at the suture, and hooked internally,
so as almost to form a ring (which it probably does in other examples) ; there are also
several orange dots—two on the base, a little further apart than the thoracic ones, two
‘on the disc behind the common mark, two united to the hook on its outer side or
nearly so, and two at about one-quarter from the apex. The legs are rather long and
pitchy.
264 SUPPLEMENT.
‘One example only has been sent of this curious species, and I have therefore not
been able to examine the details of the antenne and palpi. The body beneath is
black ; the metasternum is rugose, like the elytra.
In several respects this insect is not unlike some of the Meaporie ; but it is without
pubescence, and the sculpture is so peculiar that the systematic position of the species
is at present quite doubtful. -
SCYMNUS (p. 226).
7 (a). Scymnus verez-pacis.
Corpus ferrugineum, capite prothoraceque albidis, hoc vitta lata mediana nigra; elytris nigris nitidis, apice late
dilute ferrugineo. Long. 1°75 millim.
Hab. GuatTEMaLA, Panima and Tamahu in Vera Paz (Champion).
The distinguishing characters of this Scymnus, in the section to which it apparently
belongs, are its perfectly smooth, shining surface (no pubescence being visible on
either of the four examples referred to it), the broad, sharply-defined black vitta of the
thorax, the head and sides of the latter being white, and the red body and legs; the
metasternum and base of the hind body are darker. Itis not unlike S. bugabensis, but
the punctuation is finer, and no sign of series is found here. From S. apicalis the same
differences, as well as the total absence of pubescence, the more distinctly marked
thorax, the red body, with the elytral epipleure also red, and numerous recondite but
important characters differentiate S. ver@-pacis. |
There are two examples from each locality: in one of those from Tamahu the
thoracic vitta is more extended, occupying the whole disc of the thorax, and being
twice as wide as the pale lateral portion; possibly this example is a female, but it has
the head whitish-yellow.
COCCIDULA (to follow the genus Scymnus, p. 235).
Coccidula, Kugelann, in Illiger’s Verz. der Kafer Preuss. p. 421 (1798).
Coccidula consists of two well-known European insects of oblong form, found in wet
places, among reeds, &c. ; a third species, from the United States, has been referred to
it by Leconte and Crotch, on the authority of a single specimen; and a species from
China is placed under this generic name in the Munich Catalogue, but it very probably
is not congeneric.
The species here recorded is also doubtfully placed in the genus.
1. Coccidula (?) ferruginea.
Oblonga, ferruginea, breviter ac parce pubescens, crebre punctata; capite prothoraceque dilutioribus, minus
irregulariter subtilius punctatis, Long. 4 millim.
Hab. Mexico, Toxpam (Saldé).
COCCINELLID. 265
Oblong, entirely ferruginous, the elytra darker than the head and thorax, and more
strongly and irregularly punctured. The antenne are short, the two basal joints stout
and the second not much shorter, but smaller than the first; the four or five apical
joints form a gradually thickened club. The thorax is wider than long and has the
sides nearly straight; all the margins are finely bordered, and the sides converge
towards the front; the basal lobe is not very pronounced. The scutellum is minute,
scarcely visible. The punctures on the elytra are not at all serial (in the European
species there are larger punctures forming substriate rows), but are confluent (often in
transverse rows). The coxal fosse are complete, and somewhat V-shaped ; the external
side of the marginal line is fainter than the internal side, and is reflexed at its outer
termination. :
Only two specimens have been seen by me from Mexico; but there is a similar,
possibly identical, insect among the undetermined Coccinellide of the Crotch collection,
from Tucuman and also from Chili (Germain).
