INTRODUCTION.

TuE present volume of the Coleoptera section of the Central-American fauna deals

with the two allied Tribes Pectinicornia and Lamellicornia, well-defined groups which

include many of the largest and most striking forms of the order. ‘The genera repre-

senting the two tribes were placed by Linnzus and other early systematists, apparently

under a vague, but not less true, sense of their superior organization, at the head of

the whole Coleopterous series, a position from which they have since been deposed in

favour of the less specialized Cicindelide and allied groups of the Adephaga. ‘The

higher specialization of the Lamellicornia is clearly shown in the tendency they display

to consolidation of parts of their external structure, especially the mouth-organs, the

ligula with the mentum, and the labrum with the clypeus or epistome, and still

more clearly in the concentration and reduction in number of the ganglia of the

nervous system.

The two tribes were considered as forming one only by the eminent specialists

Erichson and Burmeister, and were separated by Lacordaire in his classical ‘ Genera

des Coléoptéres,’ in 1856, chiefly on the ground of the immobility of the antennal

lamelle, the same being movable like the leaves of a book in the more highly

organized Lamellicornia. ‘This constant difference is, however, supplemented by many

other important and significant characters, which, though constant within subordinate

groups of each respectively, do not apply to the whole tribe and are therefore of minor

systematic value, though indicating sufficiently distinct tribal types of form and lines

of development.

With regard to the contents and relations of the Central-American fauna of Pecti-

nicornia and Lamellicornia, the two tribes present such different aspects that they

must be considered separately.

In Pectinicornia our fauna is exceedingly poor in the chief family of the tribe, viz.

the Lucanide, but, on the other hand, exceedingly rich in the other and more aberrant

a 2

1V INTRODUCTION.

family, the Passalide. Of Lucanide we are able to record only 5 species of 3 genera,

whilst in Passalidee we have 67 species of 27 genera. A comparison with such allied

faunas in other parts of the world as have been worked out sufficiently to promise

approximately accurate results, seems to show that the poverty in Lucanide arises from

Central America lying too far south in the continent to have been reached by many

species of Old-World genera, which in America extend no further south than the

temperate zone, and too far north for the genera characteristic of South Brazil,

Chili, and the Andes. The conditions seem, however, to be very favourable to the

Passalidee, which here reach their highest development and exhibit more diversity of

form than in any other region. Other faunas show the following proportions :—North

America (Henshaw’s Catalogue, 1885, and Suppl. 1887) possesses of Lucanide 14

species of 5 genera, and Passalidz 1 species of 1 genus; Brazil (Gemminger and Harold’s

Catalogue, 1868), Lucanide 22 species of 6 genera, Passalidee 25 species of 16 genera.

The Colombian subprovince probably approaches our fauna nearer in its proportions of

the two families; but the data for an approximate enumeration, in this case, are not at

hand. In the tropical regions of the Old World the predominance of the Lucanide is

everywhere strongly marked. In the islands of the Malay Archipelago there are

upwards of 80 species of Lucanide of a dozen genera, and only about 27 Passalidee

of 6 genera.

The Lamellicornia are well represented in Central America in all their families. In

the following pages we are able to record the large total of 1028 species contained in

127 genera. ‘This is about one-tenth of the number described to the present date from

all parts of the world, which I find, on a rough enumeration, to be very nearly 10,000.

On comparing this proportion with those of the previously completed tribes in the

present work, we find that it is rather greater than in the Geodephaga, where the

numbers are 1086 : 12,000, and much less than in the Longicornia, of which Central

America possesses 1273 species out of the total number described, viz. 8968. A com-

parison of the Lamellicorn fauna with that of other tropical regions of similar extent

is impossible, as the necessary data do not exist in a connected form: we cannot say

therefore whether our fauna is exceptionally rich for a tropical region ; but as compared

with temperate regions, e.g. Europe and North America, it is certainly very much richer

than either. Of Lamellicornia Europe possesses only 636 species of 71 genera and North

America 523 of 75 genera. In the less tropical tribe of Geodephaga the proportion is

nearly reversed, our region furnishing. only 1086 species, as compared with 1750 and

1223 for Europe and North America respectively; on the other hand, in the more

tropical tribe of Longicornia Central America shows a still more decided superiority,

INTRODUCTION. Vv

the number of species being 1273, whilst for North America (Henshaw’s Catalogue) it

is 579, and for Europe (with the Caucasus), according to the latest edition of Heyden,

Reitter, and Weise’s Catalogue, only 473 species.

The material for the present volume has been relatively richer than that for the

former volumes on the Geodephaga and Longicornia, for in addition to that obtained

by the four years’ labours of Mr. Champion, and the fine collections of M. Sallé, Herr

Hoge, Herr Van Patten, Mr. Belt, and others mentioned in a previous Introduction, it

includes a very large collection, a portion of the fruit of Herr Hoge’s second journey

to Mexico, and another, rich in new and interesting forms, obtained by Mr. and Mrs.

H. H. Smith during their recent journey, in which they visited parts of Mexico not

previously explored. Many new species have also been obtained from Herr Conradt

and from Dr. Gaumer, who collected in Guatemala and in Yucatan respectively. Mr.

Flohr has also sent us specimens of many new species, some of the most remarkable

of which were collected in the Sierra Madre of Durango.

The total number of species enumerated in the present volume is 1100: 494 new

species ( Pectinicornia 23 and Lamellicornia 471) and 19 new genera (Pectinicornia 4

and Lamellicornia 15) are described.

Of the 1028 species of Lamellicornia, 107 are left unnamed from want of sufficient

material, such species being represented by single specimens only, often imperfect,

which, in this family, where the sexual differences and degrees of development are so

important, cannot afford reliable specific characters; these unnamed species chiefly

belong to Lachnosterna (36), Anomala (24), and Diplotaxis (13). 492 species are

figured (Pectinicornia 18 and Lamellicornia 474).

Cantharolethrus, Thomson, Ann. Soc. Ent. Fr. 1862, p. 411.

Three, perhaps four, closely allied species of this beautiful and peculiar genus of

stag-beetles are known, all from Colombia or Ecuador. One of the Colombian species

extends its range into the domain of our Fauna, and is remarkable as being, with the

exception of two small sali, the only form known to inhabit Central America of

the conspicuous Family of Lucanide, so numerously represented in all other tropical

and subtropical regtons.

Four examples, viz. two males from Costa Rica, and two females from Chiriqui. The

The examples obtained by Mr. Champion were both found crawling on tree-trunks,

in the dense forest bordering the upper margins of the coffee plantations in the

district known as “ Las Potrerillas,” situate on the south-east slope of the Volcan de

Chiriqui.

Hab. Mexico, Oaxaca !.

As no mention is made of an ocular canthus, this species appears to be a typical

4isalus. It is much larger (6 millim.) than 4. neotropicalis, and also differs in colour

and in the form of the prosternum.

2. Aisalus neotropicalis. (Tab. I. figs. 8, 3 a.)

Oblongo-ovatus, sordide fuscus, antennis pedibusque rufioribus ; supra breviter sat dense erecte setosus, opacus,

grosse discrete punctatus ; clypeo vix arcuato, oculis cantho angusto setifero dimidio divisis ; thorace fere

sicut in 4. scarabeoide; elytris interstitiis paullo conyexis, setis plerumque in striis sitis ; tibiis anticis et

intermediis extus denticulatis dentibusque acutis elongatis-tribus, 1° apicali recte exstanti, alteris duobus

Long. 4 millim.

Hab. GUATEMALA, near the city, Zapote, Capetillo (Champion).

Differs from the type of the genus, and all other members of the subfamily to which

it belongs, in the eyes being divided (for half their width) by a canthus. The-canthus

is linear, convex, and studded with short blunt erect sete like the rest of the surface.

The antenne are very similar; but the joints 6 and 7 are excessively short and acutely

produced on their inner side. The mesosternum, as in the type, forms a subvertical plate

on the front face of an intercoxal process of the metasternum, and is broadly excavated

to receive the point of the prosternum; the latter is not elevated as in 4. scarabeoides,

but planed to the level of the anterior coxe. .

Many examples, obtained by beating the withered leaves and boughs of fallen

forest trees. |

Fam. PASSALIDA.

The latest monographer of this family, Dr. Kaup, in 1871 (Monogr. der Passaliden,

Berlin Ent. Zeitschr. xv.), formulated an elaborate classification, which, as it was founded

on abundant material, and of course applied to the Passalide of the whole world, I

would willingly have adopted, as the most convenient course in dealing with a limited

fauna; but a careful examination has shown the classification to be so arbitrary and

inapplicable that I have been compelled to reject it. low far the inconsistencies may

be due to the quinary method which Kaup adopted it is unnecessary to inquire, but

the necessity of making up the number five in the species of each genus, the genera of

PROCULUS. 3

each subfamily, and so forth, is certainly accountable for some of the errors. The

Passalidee of the New World, instead of forming three out of the five subfamilies into

which Kaup divided the family, seem to me to belong essentially all to one type of

form, with very great diversity of minor characters, but no important differences of

structure. The minor differences afford tolerably trustworthy characters for the formation

of small generic groups of which Kaup established a large number, and in adopting

most of these I have been obliged to institute numerous others on the same class of

modifications, chiefly the ridges and armature of the head. I have grouped ‘the genera

into two sections, characterized by the form of the base of the elytra and the relative

length of these organs, or the hinder body, with regard to the thorax. For con-

venience of reference and comparison I have adhered pretty closely to Kaup’s sequence

of the genera, although it violates to some extent their natural affinities.

Section I. Elytra relatively short, more or less protuberant in the middle of the base.

A. Antennal leaflets very long.

PROCULUS.

Proculus, Kaup, Harold’s Col. Hefte, iv. p. 8 (1868); id. Monogr. der Passaliden, p. 65 (1871).

Three species of this fine genus, the giants of the family, are at present known. They

appear to be restricted to Guatemala ‘and the adjoining region of British Honduras.

In Guatemala P. goryt is confined to the Pacific slope, and found at elevations of

from 1000 to 5000 feet; P. opacipennis and P. mniszechi to the Atlantic slope, and to

the humid forest region of Alta Vera Paz, at elevations of from 3000 to 5000 feet;

examples of the last-named species were only met with sparingly in various localities in

this district by Mr. Champion, who, at the time not possessing means of preserving

such large insects in a very humid climate, was unable to retain examples.

Decaying specimens of these and other Passalide occasionally harbour rare

Staphylinide.

Hab. GuATEMALA+?, Pantaleon, Las Mercedes, Las Nubes above Mazatenango

This species was obtained plentifully, by Mr. Champion in the ecffee estate of Las

Nubes and elsewhere along the Pacific slope, by employing the Indians to tum over

the fallen trunks of the largest forest trees, in the decaying wood on the under side

of which the insect passes its earlier stages.

_ PROCULEJUS.

Proculejus, Kaup, Monogr. der Passal. p. 60.

Kaup gives the antennal leaflets as “short.” They are certainly much shorter than

in Proculus, but not so short as in the restricted genus Passalus and itsallies. The first

and second leaflets are more than twice the length of the body of the joints, and the —

third leaflet is moderately slender.

The leaflets have an extremely finely-shagreened sensitive surface and short pubes-

cence; in Proculus the surface is sparsely punctured and shining, and the pubescence

very long.

Five species have been described, four from Mexico and one from Ecuador.

Kaup’s P. brevis is cited with doubt, as he says the mandibles have three apical teeth.

M. Sallé’s specimens from Jacale, the locality whence came M. Truqui’s types, have only

two apical teeth.

Hab. Muxtco, Mirador! (Dr. Sartorius), Oaxaca (var.?, Sallé).

A specimen in the Sallé collection agrees well with Kaup’s description, especially in

the flattened surface of the thorax and elytra and the bidentate apex of the mandibles.

. It differs, however, in the much less extent of the punctulate and hairy lateral interstices

of the elytra, the basal portion of the tenth interstice only being so sculptured and

clothed. Kaup describes P. sartorii as having the second, third, and fourth marginal

(7. e. eighth, ninth, and tenth from the suture) interstices punctulate throughout.

5. Proculejus pubicostis. (Tab. I. fige. 4, 4a.)

Breviter oblongus; verticis cornu elongato antice libero et paullulum elevato, apud basin utrinque tuberculo

subrotundato; carinis frontalibus vix acutis divaricatis usque clypei tuberculum lateralem extensis ibique

tuberculatis ; clypeo acute marginato, fronte levissima; thorace sicut in P. brevi, sulculis marginalibus

passim angustis, punctatis, foveaque laterali punctulato-pubescenti; elytris relative quam in hac specie

brevioribus, sed antice medio paullo minus prominentibus, sulcatis, sulcis subtilius punctulatis ; inter-

stitiis 1°-6™ latis, planis, 7° angustiori, glabro, 8°-10™ punctulato-pubescentibus, 9° angusto subcarinato ;

tibiis 4 posticis extus absque spinis. .

Long. 28 millim. ; thorax 8, elytra 15 millim. long.

Hab. Mexico, Orizaba (Sallé). One example.

Named P. mexicanus, Truqui, in the Sallé collection, but evidently in error as it does

not at all agree with Truqui’s description. The antennal club has three moderately

long, thin leaflets, as in the other species of Proculejus.

This species differs from the others of this section in the tubercle of the vertex

being prolonged into a long, horizontal, laterally subcompressed horn, and in the frontal

carine being widely divergent and ending in a tubercle very close to a similar clypeal

tubercle over the base of the mandibles. As it resembles in all other characters

P. brevis, the modification in the armature of the head can scarcely be taken as a generic

character.

§ 2. Elytra entirely glabrous.

6. Proculejus championi. (Tab. I. figg. 5, 5a.)

Breviter oblongus, elytris subovatis, convexus, niger politus ; clypeo lato, carinaque antice et postice sulco levi

marginata ; tuberculo verticis parum elevato, compresso-conico, postice late sulcato, apice declivi carinisque

Long. 30 millim. ; thorax 9, elytra 18 millim. long.

Hab. Guatemata, Purula in Vera Paz 4000 feet (Champion).

Very similar to P. brevis, Truqui, in all its proportions and in the sculpture of the

head, the only differences in the latter being that the frontal carine terminate long

before the sulcus which limits the clypeus; the horn or tubercle of the vertex is broadly

sulcate behind and the depressed areze are much smoother. he thorax differs in the

dilated sulcus on the anterior margin and the perfectly smooth lateral fovea. The antennal

club has the leaflets moderately elongated and minutely sculptured in both species, and

the lobes of the mentum are very coarsely punctured and hairy. The elytra in both are

almost angularly prominent in the middle of the base, and the basal edge runs obliquely -

backwards to the rectangular shoulders. The mesosternum is glabrous and impunctate ;

the flanks of the thorax densely hairy. The legs have only a few hairs; the middle tibize

two strong spines, the hinder tibiee only one.

Although Kaup gives the punctulate-hairy sides of the elytra as one of the chief

characters of the genus, he admits one species (P. quitensis) which has glabrous sides;

this may be included in the same section as P. championi, although it differs in some

important particulars.

Several examples, found in the dense humid forest.

OILEUS.

Oileus, Kaup, Monogr. der Passal. p. 58; id. ibid. p. 117.

Differs from Proculejus in the tubercle of the head being developed into a long

horizontal horn, with a free tip projecting beyond the edge of the clypeus, and in the

obsolete frontal carine. ‘The sole species is much larger than the Proculeji, and differs

from them in the slightly impressed elytral striz. ‘The elytra are relatively longer, but

have the same prominence in the middle of the base and rather more obtuse shoulders.

Kaup founded his genus Oz/ews in his Prodromus (Harold’s Col. Hefte, v.) on a

miscellaneous set of species four in number, which he subsequently, in his monograph, |

separated into three genera with new names, transferring the name Oéleus to a species

which was not included in the original genus. It is perhaps expedient to overlook this

irregularity, as a shifting of the names again, according to the rules of nomenclature,

would only tend to increase the confusion.

PROSOCLITUS.

Gen. Proculejo affinis, sed elytris relative longioribus humerisque magis rotundatis. Clypeus flexuosus absque

latum, basi utrinque tuberculo aleformi valido, apice liberum, ante apicem cum carinis frontalibus obtusis

prominentia, humeris obtusis, basi declive punctulato-pubescenti, lateribus glabris; punctulato-sulcata,

Differs from all the genera of the section in the shape and position of the cephalic

prominences, and from Proculejus, with which it best agrees and to which it is further

allied by the moderate length of the antennal leaflets, by the much greater relative

length of the elytra.

The clypeus is distinct and separated from the front by a groove as in the allied

genera, but the groove is multiflexuous instead of straight, and, probably in consequence

of the transverse direction of the very obtuse frontal carine, there is no distinct conical

tubercle at each end of the groove. The metasternum has a patch of coarse punctures

on each side near the apex, its sides have a very narrow punctured groove, and the base

on each side near the middle coxe is punctulate-pubescent. The upper carina of the

intermediate tibiz only has a fringe of hairs, as in Proculejus.

In its quadridentate clypeus this genus agrees with Pseudacanthus, Kaup, the typical

species of which I have not seen. The two forms must, however, be generically distinct,

as Kaup says of Pseudacanthus that the antennal leaflets are “ ziemlich kurz.”

Pseudacanthus, Kaup, Monogr. der Passal. p. 73.

Kaup’s definition of this genus is not satisfactory, and although I have not seen the

typical species (P. mexicanus) I doubt whether his second species (P. laticornis) can

remain associated with it. His third species (P. aztecus) is certainly not congeneric

with P. laticornis. In the doubt concerning the form of the base of the elytra and the

length of the antennal leaflets of the typical species, it seems advisable to leave

P. laticornis at present in the genus. All the species are from Mexico. |

PSEUDACANTHUS.—PLATYVERRES. 9

According to the type specimen, which I have examined, this species belongs to the

same section of the family as Proculejus, the base of the elytra being prominent in the

middle; but the leaflets of the antenne are extremely short. The flanking tubercles

of the horn of the vertex are visible, though short and little elevated. ‘The frontal

carine and their terminal tubercles are obsolete.

PLATYVERRES.

Gen. Verres quoad verticis cornu simillimus; antennarum lamelle quoque brevissime. Differt elytris basi

haud sinuatis sed medio leviter rotundatis. Metasternum utrinque vitta depressa angusta apice haud

dilatata punctulato-pubescenti. Labrum late triangulariter emarginatum. Caput leave; clypeus planatus,

utrinque intra labri marginem dente valido apice truncato; cornu yerticis cum tuberculis lateralibus

simul elevato antice tridentato. Thorax magnus, angulis anticis late rotundatis, sulculo marginali levi

nullomodo dilatato.

Kaup placed the species for which this genus is rendered necessary in his genus

Verres, belonging to his subfamily “ Passalinz,” and therefore as far as possible apart

from Proculejus, with which undoubtedly lie its true affinities. In the very short

leaflets of the antennze it no doubt resembles the “ Passalinew,” but this is not more

than a specific character in many of the Old World genera of the family, and cannot

outweigh the form of the base of the elytra and the large size of the thorax. The

parallel-sided and narrow lateral groove of the metasternum is also not unimportant as

an indication of its true place. In Verres and all the allied large “ Passaline” this

groove is broadly dilated behind. In Proculejus and allies it is always narrow, and

sometimes reduced to an impressed line.

Kaup enumerates five species under this genus, all from Mexico and Colombia. It is

distinguished by its rather broad flattened clypeus, separated from the front by a fine or

shallow (sometimes indistinct) line, having a tubercle at each end only; and by the

oblique frontal declivity of the tubercle of the vertex, from the bottom of which spring

the frontal carine.

The antennal leaflets are moderately elongated, and the genus is not widely distinct

from Soranus of the subsection B.

The characters given by Kaup as distinguishing the two above-named genera are

evidently only of specific value: one is the free apex of the horn or tubercle of the

vertex in Weleus, which varies greatly, and another the median teeth of the clypeus,

approximated and obtuse in Welews and widely separate and acute in Ninus. The

last-named character does not hold good, specimens of Neleus tlascala var. punctiger

it occurs. A. maillei in its normal form (clypeus obtusely indented in the middle)

co-exists with it, and some Chiriqui examples show a tendency to bridge over the

difference between the two forms. . maillet and R. celatus are related to each other

in a similar way.

* PHORONEUS.

Phoroneus, Kaup, Monogr. der Passal. p. 100.

Five species are enumerated by Kaup, viz. four from Brazil and one from Peru.

1. Phoroneus jansoni. (Tab. I. figg. 17, 17 a.)

Elongatus, convexus, vix planatus; clypeo triflexuoso, medio paullo producto ibique obtuse bidentato, denteque

parvo utrinque supra labri marginem, mox pone dentes linea impressa; tuberculo verticis parum elevato,

apice haud libero; carinis frontalibus brevibus, acutis, levibus, longe ante clypeum terminatis; thorace

angulis anticis productis, sulculo marginali omnino levi antice intus dilatato, lateribus levibus ; elytris

fortiter punctato-striatis, interstitiis subconvexis, 6°-9™ paullo angustioribus, omnino glabris; metasterno

his unidenticulatis.

Long. 32 millim.

Hab. Nicaracva, Chontales (Belt, Janson).

This species has the same facies and proportions as Undulifer incisus, but is not very

closely allied to it generically. In the flattened disc (with sharp postero-lateral edges)

of the metasternum it belongs to the Weleus group, in which its entirely smooth meso-

and metasternum and sides of elytra give it generic distinction. Undulifer belongs to

a group of genera, with long antennal leaflets, in which the “ metasternum ” is evenly

convex, and the anterior angles of the thorax rounded instead of advanced, and more or

less acute, as in Weleus and allies. Although the slightly arcuated middle part of the

clypeus shows some approach to the singular form of the same member in Undulifer,

the absence of spines in the latter constitutes a fundamental difference.

SORANUS. | 19

B. Antennal leaflets short.

SORANUS.

Soranus, Kaup, Monogr. der Passal. p. 107.

Kaup enumerates four Mexican and one Nicaraguan species under this genus. Its

composition is, however, not satisfactory, as it contains species with moderately long

and species with very short antennal leaflets, the former of which have a convex and

impunctate metasternum and obtuse anterior thoracic angles, and the latter the com-

mencement of a discal plate on the metasternum, with its patch of coarse punctures on

its posterior sides, and somewhat produced thoracic angles. They are united only in

the form of the carine and tubercles of the head, the horn of the vertex being flanked

by broad tubercles, which ‘are vertical in front. Soranus recticornis is closely allied to.

Popilius.

1. Soranus haagi.

Passalus haagit, Kaup, Harold’s Col. Hefte, iv. p. 21.

Soranus haagit, Kaup, Monogr. der Passal. p. 107’.

Hab. Mexico! (coll. Haag).

Unknown to me. If, as implied by Kaup originally referring this species to the

genus Passalus, the antennal leaflets are very short, his genus Soranus should be

limited to those species which possess that character, the others, or at any rate S. recti-

cornis, being separated from it. To follow this course without examining his S. haagi

seems, however, unadvisable.

2. Soranus tropicus. |

The antennal leaflets in S. recticornis are rather longer than in the two- preceding

species, but the first is not twice as long as the body of the joint ; the anterior angles of

the thorax are rather obtuse; the metasternum convex and without trace of shield-

formation or group of coarse punctures. :

The middle tibiee have in the middle of the outer edge (not on the upper carina) an

abruptly projecting horny process, a little curled inwards, on which the long hairs are

much denser than on the rest of the edge.

5. Soranus eclipticus. |

group of coarse punctures.

Long. 21 millim.

Hab. Mexico, Orizaba (Sallé) ; Guatemaa (Sal/é).

Five examples. This species bridges over the difference between the genera Soranus

and Popilius, which Kaup places in distinct subfamilies. The antennal leaflets are

somewhat elongated, as in Soranus recticornis and S. eclipticus, and not shorter than

in some species of Popilius. As it agrees -so closely in the form and position of the

cephalic elevations with Soranus, it is better left, for the present, in the same genus

as that species, notwithstanding the flattened front edge of the clypeus.

PASSALUS.

Passalus, Fabricius, Ent. Syst. i. 2, p. 240; Kaup, Monogr. der Passal. p. 105.

Kaup included four species only in the genus Passalus as narrowly restricted by him.

As the P. cornutus of the founder of the genus is included among the four, the appli-

cation of the name to the group may be considered as justified, although that species

was not known to Fabricius when he originally treated of the genus, being first

mentioned in his subsequent work, the ‘Systema Eleutheratorum.’

The antennal leaflets in this species are much more elongated than in P. cornutus and

P. zodiacus, but they vary in length in different individuals, the first leaflet being

sometimes more than twice the length of the body of the joint.

VETURIUS.

Veturius, Kaup, Monogr. der Passal. p. 110.

and in the rugosity of the remarkably broad and deep sulci on the lateral margins of

the thorax. One small example from Costa Rica has quite faint elytral strie.

Long. 33 millim.

Hab. Panama, Volcan de Chiriqui, Bugaba (Champion).

A large number of examples. Distinguished from all other species of the genera

more immediately allied to the restricted genus Passalus, by the hairy shoulders of the

elytra. In all other essential characters it agrees with V. platyrhinus; but the cephalic

horn, instead of being conically elevated anteriorly, lies nearly flat, its flanking tubercles

being depressed and obtuse; from the elevated tubercle terminating the frontal carinze

two ridges diverge to the side of the ocular canthus, and enclose a deep pit. The

middle tibie are unispinose. The milky or subopalescent gloss of the elytra, strongly

marked in unworn’ specimens, is a striking feature. The entire lateral margin of the

thorax is visible from above, and not concealed by the convexity of the limb as in

V. platyrhinus.

SERTORIUS.

Sertorius, Kaup, Monogy. der Passal. p. 114.

One species only of this genus is recorded. It agrees with Veturius and Verres in

the metasternum having a rather broad shallow punctulate-pubescent groove, much

dilated behind, on each side; but differs from Vetwrius in the anterior margin of the

thorax being normal, and from Verres in the flanking tubercles of the horizontal

cephalic horn being basal and depressed.

Tribe LAMELLICORNIA.

In dealing with this great and important tribe of Coleoptera, the described species of

which from all parts of the world cannot now be fewer than 10,000, I have found it

convenient to follow, with but slight modifications and omitting the main divisions

founded on the situation of the abdominal spiracles, the classification given in the

third volume of Lacordaire’s ‘Genera.’ ‘The tribe has been considered by eminent

entomologists to be the most highly organized of the entire order. The “Lamelli-

cornia” are further remarkable as being more sharply severed than most others from

the nearest allied tribes: thus the plan adopted in the “‘ Carabide ” and “ Longicornia”

of the present work, of beginning with the least specialized forms (or those which show

traces of approach to other tribes), is here impracticable, as no connecting links have

been discovered. ‘There are, nevertheless, numerous genera which exhibit characters

intermediate between those of the chief Families composing the Tribe; such genera

were included by Lacordaire in his ‘ Orphnides,’ ‘ Hybosorides,’ ‘ Glaphyrides,’ and

some of the earlier groups of his ‘ Melolonthides;’* and it would perhaps be an improve-

ment to displace these genera from the position he assigned to them and make them

the starting-point of the classification of the whole tribe, taking afterwards in succession

the larger families which radiate from this common root of the whole. But this course

could not be taken with advantage in a Faunistic work; it is a task for a future

Monographer, and will entail a careful study of numerous aberrant genera from

various parts of the world, many of which are isolated forms and rare in collections.

For the present I have taken the relations of the ligula to the mentum as offering a

better main division of the Tribe than the position of the abdominal spiracles.

Subtribe I. Ligula distinct from the mentum.

species being most numerous and varied in the equatorial subzone. 135 species have

been described.

Two Nicaraguan examples in the Sallé collection are labelled “type”: these agree

in colour with Harold’s original description of the species, but not with the subsequent

one.given in his ‘Monograph.’ The species seems to be represented in Nicaragua by

one constant varietal form, in which the upper surface is shining testaceous-red, with

the head, a narrow basal margin to the thorax and elytra, and the suture of the latter,

dark brassy ; the under surface and legs brassy-black, with the abdomen (except its

basal and apical margins) and pygidium testaceous-red. In Costa Rica the local form

is similar, except that the thorax has a broad brassy-black central vitta (sometimes

interrupted in the middle), and the basal and sutural brassy-black borders of the elytra

are more or less (sometimes very greatly) dilated. Examples from Panama and Taboga

Island again differ, the thoracic vitta being narrower and dilated in the middle, the

abdomen wholly black, except the pygidium (which is yellow with a dark central line),

and the hind (and sometimes also the middle) femora testaceous-yellow in the middle.

In the form or forms described by Von Harold in his ‘ Monograph,’ who, according to

his habit, does not say to which of the numerous localities they refer, the colours are

“ piceus, thorace leviter virescente maculis quatuor in angulis dispositis testaceis, vel

omnino piceo vel rufo, elytris nigris interdum rufo-signatis.”

Bonvouloir’s collection. In the Sallé collection there are no specimens from Toxpam,

and those labelled C. spinosus (from Tuxtla, Playa Vicente, and Cordova) seem to agree

better with the description of C. speciosus than with that of C. spinosus. One, however,

from Sturm’s collection, seems to be intermediate between the two species; so that it is

possible they form really only one. It is to be remarked that Von Harold described .

his C. speciosus at a subsequent date, when he appears not to have had the type

specimens of his original C. spinosus before him.

Belongs to the C. trianqgularis group, and the subgroup C. rufulus, in which the sides

of the prosternum are without transverse carina and the hind femora ungrooved near

their anterior edge. The thorax is rather strongly but obtusely angulated in the middle

of its sides, and the seventh and eighth elytral strie are obliterated on the humeral

callus. The pygidium is dull reddish, opaque, and faintly carinated down the middle.

The legs are blackish or castaneous, with the middle (and greater part) of the femora

very pale testaceous. In well-developed examples the thorax has a strong golden-

brassy tinge.

C. moniliatus may be distinguished from the nearly-allied C. sexspilotus, Guérin, and

other neighbouring species, by the fine but sharply impressed elytral strie, in which are

small and distinct but distant punctures. ‘The variety is labelled in the Sallé collection

“C. cyanocephalus, Har., type.” It was probably named so by Von Harold on being

communicated to him after his Monograph was published, as no mention is made of the

specimen, nor is the locality Nicaragua given by him under C. cyanocephalus, which is

stated to be from “ Cayenne, Orinoco, and Guiana.” The Nicaraguan insect does not

correspond at all with Harold’s description.

Belongs to a numerous group of the genus, not indicated in Von Harold’s Monograph,

in which the robust hinder tibie are straight on their inner side and strongly arcuated

on their outer edge; generally also they are thickened and calf-like. I find that the

sexual difference in the pygidium is the same as described by Von Harold in C. angus-

tatus, this segment being remarkably short and convex; but the male anterior tibiee are

broad and tridentate (with broad and notched apical spur), and not elongated and

bidentate as in C. angustatus. An example from Juquila is figured.

C. quadriguttatus, C. subhyalinus, &c., but shorter in outline than in the larger species

of the group, and showing only a slight narrowing behind. In the feeble carine and

absence of groove along the outer edge of the posterior tibie it agrees with C. swb-

hyalinus, C. quadriguttatus (Oliv.), and C. femoralis. The clypeus has two sharp

triangular approximate teeth, and is rounded on each side immediately from the base

of the tooth, showing a slight but sharp projection at the suture of the gene. There is

a strong sutural depression at the base of the elytra, which does not extend to the thorax.

Immature specimens are glossy pale castaneous.

Allied to C. ewryscelis, but more glossy and metallic, and hind tibie distinctly less

dilated. A further distinguishing character lies in the anterior tibie, in which the

upper tooth is small] and distant from the two lower ones, whilst in C. ewryscelis all three

are large and equally close together. The clypeus is not so evenly rounded on each

side from the base of the teeth, but is flexuous, and the sharp denticle at the lateral

suture is more prominent. The angular dilatation on the side of the thorax is unusually

sharp, and the vertical arcuation of the side in front of the angle very highly developed ;

the hind angles of the thorax are prominent and acute. ‘The base of the elytral suture

is depressed, and the humeral callus free from traces of strie.

Four examples. The single specimen from Tolé is brilliant red-coppery, the others

bluish-black ; the former is figured.

The outline and dentition of the clypeus are exactly as in C. ewryscelis, and also as in

the common North-American C. viridis, from which the straight and simple inner edge

of the anterior tibie amply distinguish both the similar Panama species. The form of

the thorax is also the same as in C. lamprimus, but the surface is finely punctulated,

whilst under the same power that of C. Jamprimus appears perfectly smooth ; the elytra

differ in being silky opaque—a little more shining near the suture, and the striz,

though very shallow, are much more distinct. The thorax is dark brassy-green, with

a brilliant golden-coppery tinge on the disc. The upper tooth of the anterior tibie is

small and distant from the two lower teeth, and the hinder tibie are sharply bicarinate

down their outer edges and grooved between the carinz, as in C. Jamprimus.

Apparently closely allied to C. juvencus, Harold, but differing in the shining pygidium

studded with large piliferous punctures; in C. juvencus the pygidium is described as

“opacum, lzve.” The species belongs to the same group as the preceding and to the

subgroup having sharply bicarinate and grooved outer edge of the posterior tibie.

The scutellar depression is very slight. The punctures on the head and thorax are

large and equally distributed ; on the elytra they are rather smaller and arranged in

two rows along each interstice.

Of similar general form and colours to C. celius and its allies, and agreeing with them

dilated. It is distinguished, however, from the group by the anterior tibise being

abruptly dilated on the inner side from before the middle to the apex. Von Harold

black variety in various Mexican localities. In all the varieties the elytra are less

bright than the head and thorax, as Harold expresses it “nitidulus, elytris minus

doubtless, therefore, different, although exhibiting the same peculiar shape of the anterior

tibiee.

common South-American form are silky-black with two large quadrate orange spots on

each (sometimes united on the lateral border), one below the humeral callus, and

one covering the apical callus. The antenne are darker in colour. The oblique

position of the dorsal carina along the posterior tibie and the form of the clypeus are

the same as in typical C. lituratus.

The considerably longer mesosternum of Canthon perplexus, on which this genus is

founded, separates it not only from Canthon, but from the group of genera to which

Canthon belongs. The other peculiarities which distinguish the species have already been

pointed out by Von Harold. The form of the four hinder tibiz and tarsi and the pro-

portionate length of the joints of the latter show a nearer relationship to Canthon than

to the Epilissus and Epirhinus group; but it seems to form a step in the direction of

Cheridium rather than to form part of either group.

The Mexican examples indicate a local variety. They are smaller (10-11 millim.)

and have a much closer punctuation (the punctures stronger and ocellated) on the

thorax and ventral segments. D. parile is remarkable in this genus for the absence of

conspicuous sexual differences in the legs, sternum, and abdomen ; with the exception of

the spur of the anterior tibie (very often worn away), there is no external apparent

disparity beyond the slight difference in the sutures of the ventral segments given in the

foregoing diagnosis. In colour and sculpture it resembles D. pretiosum, Harold, which,

besides being more elongate-oblong and larger (17 millim.), presents strongly defined

differential characters in the male—the ventral segments 1-4 being consolidated in the

middle and without sutures, and the mesosternum having an oblong tubercle in the

centre ; the legs, however, remaining without apparent difference.

We figure a male example from the Volcan de Chiriqui.

narrowed to the front ; the two teeth lie as close together as in some species of Canthon ;

and on each side the margin is strongly angulated, with an additional short and acute

prominence at the suture dividing the clypeus from the gene. The sides of the thorax

in front of the median obtuse angle are straight and simple. The punctuation of the

upper surface does not differ from that of the Mexican var. of D. parile.

sinuate either before or behind the dilatation.

bisinuate sides of the thorax, but differ from the type-form in the elytral interstices

being scarcely perceptibly convex and almost destitute of shining granules *.

The figure is taken from a well-developed male example from Tehuantepec.

* It is interesting to find that the species of Deltochtlum which represents the North-American D. gibboswm

in the Amazons region is more nearly allied to the North-American than to the Central-American form, the

shape of the thorax being very nearly that of D. gibbosum. The following is a description :—

Deltochilum amazonicum.

Obscure nigro-cupreum ; thorace medio angulato-dilatato, lateribus ante et post angulum subrectis, crebre

annulato-punctato, disco simpliciter punctulato ; elytris foveato-striatis, interstitiis subplanis, annulato-

punctulatis, medio seriatim nitido-granulatis. g major ; tibise postice apice intus curvate, sublobato, lobo

apice lato obtuso.

Long. 22-28 millim. ¢ 9.

Hab. Amazons, Ega, Pebas. Some examples from Pebas have very conspicuous and elevated rows of

shining granules on the elytral interstices.

The females of this species, as well as of D. lobipes and D. gibbosum, var. subleve, vary like the males in

degree of development, and sometimes have rudimentary elytral bosses. All have rudiments of a tooth under-

neath the anterior tibiz, which are narrow and sharply bent, almost as in the males, and the deep fossa of the

metasternum is also present, but in a rudimentary state. The only constant sexual differences of outer

structure lie in the ventral segments and the apex of the hind tibiew: the former being consolidated in the

middle in the male, free in the female; and the latter produced, with an apparently short spur, in the male, and

truncated, with a long spur, in the female.

38 LAMELLICORNTA.

Mexican examples (of which I have seen only seven) are dull bluish-black.

Burmeister says “ viridi-atrum, opacum.” All the numerous specimens received from

Costa Rica and Chiriqui are of a rich dark blue colour. Well-developed males have a

moderately-elevated umbo. The species belongs to a section of the genus (Burmeister’s

Section III.) in which the “ carina humeralis” is absent, and in apparent compensation

the short carina on the humeral callus is strongly developed. The true relation of this

carina is evident when the interstices are counted, it being situated on the seventh from

the suture (the position of the callus), whilst the humeral carina is at the base of the

ninth, close to the eighth stria.

The carina exterior to the humeral one, which is the upper edge of the epipleura, is

strongly flexuous in those species which have a humeral carina, but becomes straight

in those in which it is absent, viz. in D. mexicanum and allies. .

The male in D. mexicanum is distinguished from the female by very slight characters ;

the sutures of the ventral segments are equally developed in both sexes, the segments in

the male being only a little more contracted in the middle; but the hind femora have

an obtuse tooth beneath near the apex, which is wanting in the female.

Belongs to Burmeister’s Section I., hitherto containing one species only. It differs

from DD. dentipes, besides its more oblong form and punctured head and thorax, in

wanting the strongly-marked male peculiarities in the anterior and posterior tibiz and

ventral segments exhibited by that species. Burmeister gives as a character of Section I.,

“‘ Elytris in margine externo bicarinatis,” but does not point out the singular homolo-

gical relationship of the carine to those of the rest of the genus. In fact, the usual

short humeral carina becomes here the margin of the elytra, and runs from the base

nearly to the apex, the true marginal carina, 7. ¢. the upper edge of the epipleura, being

removed to the middle of what consequently becomes an epipleura, augmented by the

addition of one of the normally dorsal interstices. In correlation with this the

remaining dorsal interstices are expanded laterally. The second carina is nothing but

the elongation of the outer carina on the apical callus. The humeral callus on the

same (seventh) interstice is absent.

An example from Tlacotalpam is figured.

Ann. Soc. Ent. Belg. xvi. p. 192.

A well-known Old-World genus, ranging from Southern Europe siseowo the whole

of Southern Asia (including Ceylon), and through Africa to the Cape of Good Hope.

It appears not to be known in the Malay Archipelago, Australia, or in any Oceanic

Island; but reappears in Mexico and Central America in a single species. The

Mexican species, contrary to what might be expected, offers no marked peculiarity to

distinguish it from the ordinary type of the Old-World members of the genus, and in fact

is closely allied in form and sculpture to the Indian S. Jongipes (Oliv.). The conclusion

is scarcely to be avoided that the species has followed man in his migrations.

Kirsch describes one sex only; apparently from a single example, 15 millim. long.

The species varies in size from 14 to 22 millim. Therufescent elytra described by him

is the result probably of immaturity; most of our examples are above of a dull olive-

black, and beneath dark glaucous-green. In the male the hind tibie are angularly

bent and laterally flexuous, in some examples to an extraordinary degree, and armed

beneath with a large bicuspid tooth before, and two separate teeth behind, the middle,

the large tooth sometimes much reduced or entirely wanting, the apex pointed and

without spur. In the female the hind tibie are simply arcuated, with a few small

denticulations beneath, the apex with a long free spur.

Of similar large size and elongate-oblong form to E. claudicans; but differing from

that species by its opaque velvety upper surface, and rich coppery or brassy-green

subsericeous under surface, with the legs wholly also metallic. The secondary sexual

characters as above indicated are also entirely different. As in H. claudicans, the

marginal carina of the elytra, formed by the upper edge of the epipleure, is not

elevated as in the species allied to E. planus; and the humeral carina is very short and

obtuse, and not continued beyond the point where the epipleural margin curves upward

from the base.

Most examples are uniform opaque, sooty black above, with brassy-black legs; but

in others the elytra are more or less variegated with dull red. In both sexes the

metasternum has a rounded fovea in the centre, and the hind femora a strong spine

beneath towards the apex. The humeral carina of the elytra is prolonged to three-

fourths of the elytral length, and overtops the lateral carina, 7. e. the upper edge of the

epipleura, except towards the apex.

We figure a specimen from Juquila.

Compared by Kirsch with E. meaicanus, but much more nearly allied to #. planus,

Dalm., having, like that species, a very short humeral carina, and an acute strongly

elevated epipleural carina. From F. planus it differs in the male only having a spine

underneath the hind femora (in H. planus the spine exists in both sexes); and in the

EURYSTERNUS. Al

metasternum being unarmed between the hind coxe, instead of having a compressed

and acute tubercle. Dalman says ‘‘Sterno inter pedes anticos in spinam producto,”

but anticos is evidently here a slip for postzcos.

carina.

Agrees with E. meazicanus in the nature of the lateral carine of the elytra; but the

epipleural carina is rather more strongly curved upwards, and approximated to the

more obtuse inner carina—a peculiarity pointed out by Von Harold, though he does

not compare the structure with that of EL. mexicanus. 'The species is much smaller

than EL. mexicanus, and differs in the hind femora not showing the remarkable dilatation

and compression of that species.

Von Harold describes the female only. The metasternum is similar in both sexes,

having a round central fovea, with an obtuse carina thence to the apex; but the hind

femora present a singular sexual peculiarity in having a strong spine beneath in the

female, and being unarmed in the male. The hind tibie ( ¢ ) are not greatly prolonged

on the inner side at the apex as in other species, but are spurless.

Sallé collection. ‘The species is allied to HL. empressicollis, Casteln., from Colombia ;

in both the thorax is very uneven, and the hind tibiz in the male prolonged at the

apex into along and sharp spine, simulating a spur. The spine is very much longer

and more spur-like in the Colombian species.

A genus allied to Urorys and Aphengium, but distinguished from both and from all

other “Cheeridiine” by the form of the posterior tibie, which in their gradual

dilatation are somewhat intermediate between those of Cheridium and Canthon, and in

the remarkable form they assume in the hindmost pair of the male resemble those

_of no other genus. The hind femora of the male have on the under surface a straight,

finely-serrated edge, ending before the apex in a short sharp tooth.

The marginal carina of the elytra is sharper than in A. sordidwm, and is continuous

broad, compressed and subtriangular tarsal joints are a remarkable distinguishing

feature. The anterior cavity of the prosternum is exceedingly deep.

UROXYS.

Uroxys, Westwood, Trans. Ent. Soc. Lond. ser. 1, iv. p. 229 (1842) ; Harold, Col. Hefte, i. p. 33

Seventeen species of this curious little genus, confined to Tropical America, have

been described.

1. Uroxys micros. (Tab. II. fig. 22.)

U. pygmeo (Harold) affinis, paullo major, elytris perspicue crenato-striatis, etc. Oblongo-ovatus, nigro-eneus

vel ferrugineus, politus ; clypeo bidentato, juxta dentes leviter sinuato nec subdentato, vix punctulato,

vertice levi; thorace levi, sulco submarginali profundo, basi immarginato, distanter punctato; elytris

circulari profundissimo.

Long. 4-43 millim.

Hab. GUATEMALA, La Gavia 2000 feet (Champion).

The singular curved sulcus on each side of the base of the pygidium exists in

U. pygmeus, but it is broader and deeper in the present species. The sides of the

thorax exterior to the marginal furrow are also more convex in U. micros than in

U. pygmveus. The eyes above are large and the mesosternal suture angulated, as in

the rest of the genus.

2. Uroxys aphodioides.

U. elongato (Harold) affinis; minus convexus, niger, nitidus, vertice cuprascente; capite fere levi, vertice valide

bidentato, fronte tuberculo conico; thorace (elytris latioribus) subtilissime punctulato, sulco laterali

' flexuoso margineque medio angulato et antice arcuato, basi punctato-marginato ; elytris crenato-striatis,

Hab. Nicaragua (coll. Batés).

One example, which, from the absence of curvature in the anterior tibie, I judge to

be a female. It was obtained, I think, from Dr. Seemann’s collections made at Javali.

It resembles U. elongatus in little except the uni-tuberculate forehead.

A genus, so far as at present known, peculiar to America. The great majority of its

species belong to the tropical regions of the continent, and only a few inhabit the

temperate zones north and south. Nearly forty species have been described.

1. Cheridium iilesum.

Cheridium illesum, Harold, Col. Hefte, iv. p. 53°.

Hab. Mexico1, Tuxtla (Sallé), Tonila in Colima, Jalapa (Hége).

Belongs to a group of closely-allied species, of which the well-known C. capistratum

of North America may be taken as the type. It is larger than C. capistratum and more

oblong. According to a specimen in the Sallé collection labelled C. ille@sum in Von

Harold’s handwriting, it is distinguished from that and most other nearly-related species

by the nearly plane pygidium (“leviter convexum” according to Von Harold), the

scarcely widened last ventral segment and the faintly punctured fore margins of the other

ventral segments. The thorax is smooth, except in the middle of the base, which is

narrowly margined. As to the obsoletely-punctured elytral strie adduced by Harold

as a distinguishing character, this seems to be variable, the striz (especially towards the

sides) being sometimes as strongly crenate-striate as in the allied forms.

2. Cheridium chrysopyge.

C. illeso proxime affine; majus, aterrimum, politum; pygidio plano, medio vix perspicue carinato, viridi-aurato

splendidissimo, oblongum ; thorace margine laterali prope angulos anticos verticaliter arcuato, basi anguste _

Hab. GuatEemMAta, San Geronimo (Champion).

A large number of examples, all alike except in size. The species differs from

CH@RIDIUM. 45

C. illesum in very little except size and colour; the central carina of the pygidium is

very faint, and visible only in certain lights, or in some female examples quite obsolete.

In well-developed individuals the pygidium, under a lens, appears finely and sparsely

punctured.

3. Cheridium klugi.

? Cheridium nitidulum, Casteln. Hist. Nat. Ins. Col. 11. p. 83’.

Hab. Mexico 12, Cordova (Sal/é).

Von Harold gives the size as 33-4 lines, but a specimen I received from him named

C. klugi measures barely 3 lines; the size given by Castelnau for C. nitédulum, viz.

22 lines, is therefore no reason for excluding his species from the synonymy, though his

description is too vague to be relied on. Specimens named C. nitidulum, Casteln., in

the Sallé collection measure 24 and 3 lines, and agree with Von Harold's named example

and with his description. The form is oblong, as in C. dlesum, and the pygidium is

only a very little more convex than in that species, with which the minutely punctured

bases of the ventral segments also agree. ‘The species is barely distinguishable by its

rather more convex elytral interstices, deeper and more strongly crenated strie, and

strongly impressed dorsal lines of the thorax, the base of which is very finely margined.

The sexual characters are the same as in C. illwswm. ‘The punctuation of the thorax

male.

Taken by Mr. Champion in great abundance.

The elytral striae, as in all other species of the C. capistratwm group, are deepened

and broadened towards the apex, before which they terminate. ‘The base of the thorax

appears to be immarginate, but on close inspection a narrow line is in some examples

seen at a little lower level than the apparent base.

Closely allied to C. candezet and C. simplex, but differing from both in the whole

surface of the pygidium being polished, and, further, in the centre being marked with

an impressed line or elongated fovea, which in one of the two examples is constricted

in the middle. The three species belong to a group which differs from the C. capis-

tratum series only in the elytral strize not being distinctly broader and deeper near the

apex. In both the apical border of the elytra forms a wheal or callus on which the

strie terminate before the apex itself.

p. 60.

A genus of small Copride; like Cheridiwm, peculiar to America and still more

numerous in species. ‘The range is somewhat different from that of the Cheridia,

inasmuch as it does not extend to temperate latitudes in North America, although

many species occur in the southern temperate zone; and one, apparently a recent

colonist, occurs in the Sandwich Islands. In general the species have nearly the same

facies as the Cheridia, and many are only to be distinguished on close examination of

their structural characters. In cases of doubt the very short mesosternum is the best

cuide, this segment being long in Cheridium and separated from the metasternum by

an arcuated suture. Nearly ninety species have been described.

the accustomed transverse punctures, except in rare cases when a few are perceptible in

at distant intervals with minute punctures; the interstices rather closely and very

finely punctured, besides being minutely shagreened. The thorax is more strongly

* punctured, but less so than in the ordinary blue Mexican form of C. puncticolle. ‘The

clypeus is rather coarsely and subrugosely punctured (far more so than in C. ardens),

the vertex behind less densely punctured.

Canthidium letum, Harold, Col. Hefte, i. p. 53°.

Hab. Muxico!; Guatemaua, Senahu (Champion).

According to the description this species must be similar to C. awrifex in form and

sculpture, having a trituberculate forehead, smooth thorax, and crenate-striate elytra,

in which the sutural stria is more deeply impressed than the others; the colour differing

in being bright green or slightly coppery-green. This description nearly suits a species

of which Mr. Champion met with two examples in Guatemala; but I have seen no

Mexican specimens to fit it. A specimen labelled C. /etwm, in Von Harold’s hand-

writing, in the Sallé collection does not at all agree with the description, the forehead

being unarmed, the thorax as strongly punctured as in C. puncticolle, and the sutural

stria not more deeply impressed than the others.

A species differing in the form of the head from the typical members of the genus.

The punctures along the base of the thorax are not elongate as in Von Harold’s Group L,

but small and rounded, and not forming a distinct margin. In some points of structure

the species approaches Scatonomus ; but the hind tarsi are not so broad and compressed

as in that genus, although the first and second joints are broader than usual in

The type-specimen (2) in the Sallé collection is the only one I have seen of this

insect. The species is rather elongate and robust, distinguished by the deeply

impressed and punctured dorsal line of the thorax. The clypeus is entire, and the

forehead armed with a conical tubercle as in the female of O. sulcator (Fabr.). The

front of the thorax is declivous, with indications of two obtuse tubercles on the edge of

the declivity, and the sides present a reniform elevation below the fovea similar to that

of O. quadratus. The metasternum is convex, furrowed down the middle, and strongly

punctured and reddish-hairy on the sides.

The varieties or lower developments of the male are not distinguishable from the

female otherwise than by the tridentate anterior tibie.

Erichson’s description fits exactly the common form of the female of this widely-

distributed species, in which the edge of the thoracic declivity has two obtuse tubercles.

Well-developed and rarer individuals of the same sex have four, as in O. mexicanus, & ,

from which they are distinguishable only by the shallower crenate-punctate strize of

the elytra. ‘The thorax has no dorsal impressed line and the lateral fovea is simple.

Belongs to the group of small species, with undifferentiated sexual characters in the

armature of the head and thorax, of which many have been insufficiently described. The

present species seems to be very similar to P. inachus of Erichson, the vertex having a

shallow depression behind the simple and short tubercle, as I infer from the description

of that author, “ capite ruguloso, tuberculo frontali postice impresso;” a description

equally applicable if it refers to the tubercle, which in the male is concave behind.

Erichson, however, does not mention the marginal groove of the thorax, the narrowness

and perfect smoothness of which are very characteristic of P. yucatanus, the numerous

allied species from the northern parts of South America which I have examined having

the groove punctured or punctured and widened. A female specimen from Yucatan

readily distinguishable (but in the male sex only) by the head having two tubercles, one

PINOTUS.—COPRIS. 53

before the other, P. carolinus having one only. The species varies greatly in size and

general form ; and in the shape of the cephalic tubercle, which in well-developed male

examples is sometimes obtusely pointed and sometimes broad and emarginated at the

tip. Extreme forms differ considerably from North-American specimens of P. carolinus ;

but many male examples, especially from Guatemala, offer no difference worthy of note

from others of the middle Atlantic States of North America.

P. eremita, Harold, from Colombia is a closely allied form; but I do not venture to

refer the Central-American series to it, as two male examples from Colombia, which I

have been able to examine, offer a modification in the shape of the cephalic tubercle

which does not occur in any of the Central-American specimens.

The two tubercles of the head (6), which constitute almost the sole differential

character of this species, seem to be the result of inferior development, owing to unknown

local causes. It is a prevailing rule in the horned Copride (as in other analogous groups)

that the smaller and feebler males lose the strongly developed armature of the larger

males and resemble the females. ‘This is exemplified in the present case by the hinder

tubercle of the male, which is the homologue of the same prominence in the female,

and which disappears in the male of P. carolinus; whilst the anterior tubercle, which

is extremely small in feeble males of P. colonicus, becomes larger and more elevated

according to the degree of development of the larger males. In P. carolinus the hind

tubercle (a female character) disappears in the males altogether.

About eighty species have been described of this fine genus of Copride, one of the

characteristic forms of the American Fauna. As usual, the tropical zone yields the

greatest number and variety of species; but the genus is well represented in the

warmer temperate regions both north and south, and shows no falling off there as

compared with tropical congeners in richness of colouring. Central America contains

a large proportion of species, mostly belonging to one group, and offering less variety

of forms than tropical South America.

dation in the armature of its head and thorax :—

(Wallis, coll. Bates).

Mr. Champion obtained three examples, all males of low stage of development; two

of them have a slight trace of metallic edging near the anterior and posterior angles of

the thorax and at the base of the pygidium. ‘The single well-developed male from

Colombia (Cauca valley?) is more distinctly margined with green or fiery-copper in

the same situations; it has also an almost impunctate thorax, the lower developments

showing a coarser punctuation on the sides.

Compared with males of P. chryseicollis and P. auricollis, the male, major, shows an

important difference in the posterior horns of the thorax, these being very much closer

together than in either of those species.

We figure a male, minor, from Bugaba.

Ecuador 1,

Murray described this beautiful and interesting species from a single example, a

male of small size and low development, in which the frontal horn was of moderate

height, and the armature of the disc of the thorax reduced to two laterally compressed

tubercles. The highly developed male has a very different appearance, the thoracic

elevation being, as usual in such cases, removed to the hind part of the disc, and the

tubercles in the middle of the front edge of the elevation developed into excessively

long, cylindrical but pointed, spines reaching the tip of the clypeus. In a lower grade

of males the thoracic spines reach only the front edge of the thorax, the grade described

by Murray being still lower than this.

In the female the head has a tri-tuberculate carina, and the thorax near the middle

of the anterior margin a very flexuous and fine carina, the middle of which advances

forward in an acute angle ending in a tubercle. This carina forms the front edge of

an eminence, bordered on each side by a deepish cavity and concave above.

P. velutinus is closely allied to P. chryseicollis and P. noctis. The whole upper

surface is black, with a silky lustre, except the lateral margin of the thorax (from the

eye to the basal side of the hind angle), which is of a brilliant fiery-coppery hue, with

golden-green reflections. The pygidium and the four hind femora are of the same

metallic hues.

Von Harold describes the male as “niger opacus,” and the female as “ ceruleo-

viridis nitida.” All the male examples I have seen are either rich dark blue, or

dark brassy-green; in both cases with blackish elytra. The strie of the elytra vary

in being either smooth or crenate-punctulate. ‘The numerous females are shining dark

blue, with the thorax sometimes slightly greenish, with a black antero-discal spot.

The male shows fine gradations of development in the length of the horn and in the

width of the plane and sloping triangular dorsal plate of the thorax, and the lowest or

effeminate stage is precisely as described under P. endymion. In the female the

singular difference in the prominence on the anterior disc of the thorax is constant,

and no doubt specific, the three tubercles rising singly out of the convex slope of the

surface, without trace of carina or depression behind them.

There were two examples in Herr Hoge’s collection, one labelled “ Misantla” and

the other “Oaxaca.” As a large part of his collection was labelled wrongly ‘‘ Oaxaca,”

and the Misantla specimen bears a special numbered ticket, I think it safe to conclude

that the latter is the correct locality of the species.

Von Harold separated P. divisus on the ground of a slight difference of relative

position in the tubercles on the sloping disc of the thorax ; the tubercles exist in the

complete number of three only in males of the greatest development, and the difference

between P. mexicanus and P. divisus lies in the anterior tubercle being in the former

more or less close to the two hinder ones, and in the latter distant from them. On

comparing, however, a large number of well-developed males, it is at once seen that all

grades in the relative distance of the tubercles are exhibited, and that the division

into two species must be quite arbitrary. Besides, individuals thus compared show no

difference in other respects when they differ in the position of the tubercles. In males

of secondary development the anterior tubercle disappears; in others of still lower

grade all three are wanting. .

The species varies very greatly in its rich metallic colours. The brightest form, of

resplendent golden-coppery hues, is chiefly found in Southern Mexico. A beautiful

dark blue variety occurs at Izucar. The female also varies greatly in size, colours, and

in the form and degree of prominence of the thoracic carina; it is, however, always

distinguishable from the same sex of P. sall@i by the carina not bemg sharply tuber-

culated in the middle, nor followed by a concavity. From the females of P. wagneri

and P. amithaon it may be generally distinguished by the absence of punctiform ”

impressions; but, as already observed, in some females (as well as males) of P. wagneri

these small punctiform impressions are wanting. ‘This indication being absent, I see

no other means of separating the females of these three closely-allied species.

in the armature of the males. Nearly six hundred species have been described, and in

all, with very few exceptions, the horns, protuberances, and processes exhibit individual

variations, the rule governing which is not easily traceable. America, North and

South, seems to contain much fewer species than the Old World, the tropical regions

of Africa and Asia furnishing the greater number, as well as the largest and most

richly decorated forms.

According to Von Harold ? the only difference between O. curvicornis and O. incensus

lies in the form of the anterior protuberance of the thorax in the male, the protuberance

ONTHOPHAGUS. 67

being porrect and conical in the former, and less advanced, rounded, and slightly in-

dented in the latter. It appears to me, however, doubtful if the Central-American form

referred to O. curvicornis can be really the same species, as, amongst the very numerous

well-developed males I have examined from all parts of the region, not a single one

is found with the conical protuberance of the South-American type-form described

by Latreille; in all the thorax has the same form as in O. incensus. But there exists

another character by which the males of both the Central and the South-American

forms of O. curvicornis are distinguishable from O. incensus, viz. the absence of a

carina connecting the bases of the cephalic horns. In O. incensus this carina is always

visible, though it is less acute in some examples than in others; but in O. curvicornis

there is no trace of a carina. O. curvicornis is nearly always black or bluish-black,

with a brassy-green tinge only on the crown and near the anterior angles of the

thorax. O. incensus, on the other hand, is nearly always wholly metallic above ;

generally dark brassy-green, but sometimes dark blue, coppery-brown, or brassy-

brown, with a brilliant coppery thorax. In both species the inner apical angle of

the male anterior tibiz is prolonged and more or less reflexed; and the elytra

are finely crenulate-striate, with the interstices rather thickly, irregularly, and finely

punctured.

The head is similar in form to that of O. curvicornis and O. incensus, 1. é. with

bi-cornuted vertex ; but the clypeus is obtusely rounded, and there is a deep notclvat the

suture separating it from the rounded gene; the head in the male is distinctly

bi-carinated. The thorax and elytra are usually testaceous-yellow, with the disc of the

former and the alternate interstices of the latter dark brassy-green. The dark colour

Similar to O. incensus, from which the male is readily distinguished by the carinated ~

forehead and pointed clypeus. It is also a much smaller insect. ‘The female is with

difficulty to be distinguished from small and feebly-developed female examples of

O. incensus; there is, however, generally perceptible a slight difference in the outline

of the clypeus—0O. incensus, 2, showing a trace of sinuation in the reflexed apical

margin, which is quite absent in O. acuminatus, °.

The outline of the gene is continuous with that of the clypeus. In the lower

the anterior prominence of the thorax is similar to that of the female.

The following is doubtless a local variety of this species, the absence of hairs from

great part of the surface in the single example being probably due to artificial causes ;

in other respects it differs from the Mexican type-specimen of the male only in

* This curious and beautiful little group appears to be peculiar to Tropical America. Other species

sexes have two pointed horns on the vertex ; and the front edge of the clypeus in the male

bears an erect horn dilated at its apex, and is bidentate in the female. This strange

armature attains a high degree of development in the stronger males, the clypeal horn

being dilated at its apex in horizontal semilunar form, and the horns of the vertex

elongated and curved ; but all grades of degradation of this armature, as well as of the

anterior tumid process of the thorax, occur in the large series of individuals collected

by Mr. Champion, down to a form in which there is nothing except the absence of a _

frontal carina to distinguish the male from the female. In well-developed females the

horns of the vertex are erect, parallel, and reach nearly to the level of the thorax, but

in feebler individuals they are reduced to small conical tubercles, as in the effeminate

males ; in neither sex are the horns connected at their base by a transverse carina. The

thorax, in its highest male development, is nearly vertically declivous in front, with a

very shallow depression on each side to receive the horn, and the central convexity

laterally compressed and divided into two wheals by a longitudinal furrow, the wheals

in males of lower development and in females being reduced to the form of tubercles

similar to those of all forms of O. rhinolophus.

The colour is dark castaneous or pitchy-brown, glossy above, and more or less

metallic-coppery or eeneous; the legs generally dark pitchy-red, but sometimes lighter

rufous. ‘The elytra are much more strongly sculptured than in O. rhinolophus, and the

interstices are more convex.

We figure a pair of the type-form from San Isidro. Mr. Champion met with this

insect in rotten fruits, especially in cacao; all the Guatemalan localities are on the

lower parts of the Pacific slope.

Hab. Costa Rica (Van Patten); Panama, Bugaba (Champion).

A transition form between the groups O. rhinolophus and O. sharpi; but more nearly

allied to the former, from the species of which it differs only in the horns of the vertex

being reduced to very short conical tubercles ; and the thoracic tubercles, in compen-

sation, being greatly lengthened, so that they appear, viewed from above, like two

spines projecting much beyond the hind margin of the head. It is just possible that

a more developed form of the male exists, having posterior cephalic horns, but there

is none such in the fine series collected by Van Patten.

We figure a pair from Costa Rica.

Hab. Nicaragua, Chontales (Belt) ; Panama ! (Boucard), Bugaba, Caldera in Chiriqui

Belongs to a subgroup (including the four following species) in which the males have

a clypeal horn similar to that of O. rhinolophus and its allies, but no trace of horn on

the vertex. O. sharpi is deep glossy-black, with very scant punctuation. The male

presents similar gradations in the development of the horn to those described under

O. belorhinus.

In the Sallé collection is a female example (from Santecomapan, Mexico) very

similar to O. sharpi in form and sculpture, but different in its rich metallic coloration,

the elytra being violet-black, the head and thorax golden-coppery, and the sternum

and femora brilliant neous. It would not be safe, in the absence of male examples,

to describe this as a separate species.

others, the apex obliquely truncated. The head is rather short; and the outline of the

_ genx and clypeus together forms a semicircle, except for the two triangular apical teeth

which rise obliquely upwards separately and direct from the margin. ‘The tubercles

of the vertex are stout, elevated and transverse, each forming a very short and much

elevated carina: these lie much nearer the anterior carina than the usual position of

the hind carina of the females in the genus Onthophagus. ‘The anterior cavity of the

thorax extends from the fore margin to beyond the middle, and narrows posteriorly: it

is smooth at the bottom and the ridge that bounds it on each side is compressed and

sharp in the middle, showing that the structure is but an exaggerated modification of

the antero-dorsal tubercles of both sexes in the O. rhinolophus group. We have here,

however, an additional armature in a robust horn or spine, rising, slightly curved

upwards and backwards, from the middle of the anterior margin of the thorax.

This species may be considered the type of a distinct group of the genus (including

the six following) in which the head in the male is unarmed and smooth on the

surface; the armature of the thorax restricted to one or more short lobular prominences

near the fore margin; and the anterior tibie of the male greatly elongated, with pro-

duced inner apex, within which is a long pencil of hairs. O. landoltéi varies much in

colour: the elytra are most frequently dark brassy-brown, with pale reddish spots at the

shoulders and apex; but the reddish colour is sometimes extended, and an extreme

variety occurs near the city of Guatemala in which the elytra are wholly tawny-brown.

This species is labelled in the Sallé collection O. posticus (Chevr.), under which MS.

name it is probably known in other collections. Dull-coloured examples with unspotted

elytra are distinguishable from O. anthracinus only by the stronger punctuation of the

thorax and more uniform convexity. A male example from the Volcan de Chiriqui is

figured.

In well-developed males the two middle tubercles of the thorax are produced as a

they are much reduced, and scarcely overhang the front edge of the thorax; the lateral

tubercle on each side is distant from, and posterior to, the central pair, and is never

distinctly prominent.

ONTHOPHAGUS. 79

In what appears to be the well-developed male of this singular species the posterior

carina of the head is curved anteriorly in horseshoe-shape, and advances (becoming

more sharply raised) beyond the usual situation of a frontal carina, traces of which are

seen on the sides. ‘The front edge of the clypeus is reflexed, and forms two rounded

teeth ; between these frontal teeth and the gene the clypeal margin is strongly flexuous,

and the gens are rounded and sublobate. The large thoracic prominence is nearly

straight and somewhat sharp on its front edge; the latter overhangs the anterior margin

of the thorax, and is rectangular at either extremity. A male from Cordova is figured.

This and the preceding species are acknowledged by Von Harold to be very closely

writing that the males exhibit the differences he specifies, which are, on O. retusus, the

less opaque, metallic, and more coarsely punctured thorax, the posterior carina without

distinct tubercle in the middle, the convex elytral interstices, &c.; but in a large series

these characters are seen to be variable, and it is doubtful if the specific differentiation

can be maintained.

A genus distributed over the tropical and warm temperate zones of the eastern and

western continents, but not found in Australia or in oceanic islands. Only two species

have hitherto been detected in America, namely—one in the West-Indian Islands, and _

a second in California. Forty-four species have been described.

The remarkable new species described below, recently discovered by Herr Hoge in

Mexico, differs from all other known members of the genus in the armature of the

thorax; but as very great diversity exists in the genus in this respect as well as in

general form and sculpture, and as the Mexican species agrees very closely with Oniti-

cellus in all essential points of structure, there is no ground for treating it as a

separate genus.

head and less prominent gene.

13. Aphodius ——?

Hab. Mexico, Northern Sonora (Morrison).

A species sent by the late Mr. Morrison as the A. ursinus, Motsch., an insect known

previously only from Alaska and Kamchatka, and, according to Von Harold and Dr.

Horn, belonging to the section having equal apical setz to the hind tibie. Morrison’s

species certainly agrees very well with the descriptions of both authors, with the excep-

tion that the apical sete are decidedly unequal; hence I hesitate to adopt the name.

It is closely allied to A. flohri.

APHODIUS. 87

Belongs to the same group as the preceding (Dr. Horn’s Group K and Erichson’s

Group N), from all the known species of which it differs by its deeper and coarser

sculpture. It also differs in the lesser inequality of the apical sete of the hind tibie.

The sete are all short and at first sight appear equal, but on close examination of well-

preserved specimens a slight but distinct difference of length is evident. The reddish

spots on the reddish-brown elytra are ill-defined, but more distinct on some of the

interstices at the base; in some examples the elytra appear vaguely tessellated

with red.

pallide testaceis, femoribus medio nigris, his conspicue punctatis.

Long. 4-44 millim.

Hab. Guatemaa, Totonicapam, Quiche Mountains (Champion).

Belongs to a group numerously represented in the temperate and boreal regions of

the Old World and in North America, with which it disagrees only in the apical sete

of the hind tibie being short and nearly equal in length; the usual elongated sete are

wanting, though some are a little longer than the others. The base of the thorax is

finely margined. In the number and arrangement of the black elytral spots it agrees

best with A. inguinatus, but the discoidal spots are all detached and oblong-quadrate

in shape: there are two on each of the second and fourth interstices and one (posterior)

on the sixth, the lateral larger spot forming an irregular vitta anteriorly on the sixth

to the eighth.

Our examples were captured at elevations of from 7000 to 10,500 feet.

88 LAMELLICORNIA.

Costa Rican examples are a little darker in colour, and have more distinctly convex

elytral interstices than those from Mexico. The species resembles A. brasiliensis in

form and colour, and especially in the characteristic marking near the apex of the elytra;

but it belongs, according to the received classifications of the genus, to quite a different

section: A. brasiliensis having equal apical sete to the hind tibiz and a trituberculate

head, the base of the thorax remaining, as in A. duplex, immarginate. It must be

observed that the inequality of the apical sete is not the same in A. duplex as in the

A. prodromus group, the long bristles are near the outside of the fringe and not sub-

alternately mingled with the short bristles.

An example from Costa Rica is figured.

Hab. GuareMata, Quiche Mountains, Quezaltenango, Duefias, San Gerénimo, San

Joaquin, Balheu (Champion). Many examples.

Belongs to a group of very small, closely allied species, which tend to form geogra-

phical varieties distinguished by colour and markings. Its chief characters are :—

(1) the finely impressed elytral strie, which are not squarely scored, but are simple lines

APHODIUS. 89

finely crossed by small crenulating punctures; (2) the equidistance near the apex of

strie 1-5; (3) the very fine punctuation of the disc of the thorax and of the elytral

interstices,

The typical form here described is nearly black above, with a tawny spot on each

side of the head and at the apical angles of the thorax, and with tawny vitte on the

elytral interstices two, three, and four from the base, more or less abbreviated posteriorly,

a spot of the same colour on the shoulders, and sometimes a spot on the fourth inter-

stice towards the apex. The following are evidently colour races :—

Closely allied to A. fuliginosus, but less opaque, the head and thorax being always

shining and black, and the elytra having an oily gloss, which, however, is shown in less

degree in some examples of A. fuliginosus. But a more definite character exists in the

structure of the tarsi of the middle pair of legs in the male: in A. fuliginosus the tarsi

are much shortened, with nodose joints 2-4, and thickened claws toothed at the base ;

in A. hégei they are slender, nearly as in the hind pair, the claws remaining toothed

within at the base. Durango specimens are glossy and considerably larger in size; in

the numerous examples examined I find no other difference.

There are many examples in the Sallé collection, including a type specimen bearing

a label in Von Harold’s handwriting. According to these the species varies considerably :

in size from 44 to 6 millim.; in colour from black to livid-castaneous; in the depth

and strength of the punctured striz, which are sometimes deeply gouged with bilineated

bottoms, and in rare cases quite superficially impressed ; in the hind angles of the thorax

—sometimes rounded and sometimes nearly rectangular; and in the truncation of the

clypeus being, especially in small examples, scarcely perceptible.

The Sallé collection contains no examples of this or the preceding species labelled by

the describer ; but there is a series of each named by M. Sallé, all of which seem to me to

belong to one and the same species. As none of the differential characters mentioned

by Von Harold hold good, I am inclined to think they are not distinct. All the specimens

have convex elytral interstices, and a more or less distinct tooth at the inner base of the

tarsal claws in all the legs. The punctuation of the upper surface varies indefinitely,

and the silky surface is more or less perceptible in all *.

SAPROSITES.

Saprosites, Redtenbacher, Fauna Austriaca, Kifer, 2nd ed. p. 486 (1858).

This genus was founded by its author on a minute Aphodiide found in orchid-

houses at Schonbrunn, and supposed to have been imported from America; Von Harold

gives the locality as Colombia. Redtenbacher omits to mention the characters distin-

guishing the genus from Huwparia, and from the species belonging to the subsequently

proposed genus Atwnius: these, according to Von Harold (incidentally stated in his

diagnoses of various species), are the traces of transverse carine on the outer side of

the four hind tibize and the dentiform projections on their apical margin; but there is

little doubt that the numerous species referred to Saprosites by Von Harold are really

congeneric with Redtenbacher’s type. I would, however, exclude such species as

Saprosites sulcatus, Harold, which have a simple fringe of bristles to the apical margin

of the four hinder tibie.

Upwards of twenty species of Saprosites have been recorded. The genus has a wide

range, including, according to Von Harold, besides Tropical America and Tropical Asia,

Japan, New Zealand, and some of the tropical islands of the Pacific. The flattened

species which I observed in the Amazons region were found under the close-fitting bark

of trees, in company with similarly flattened Cossonide and Cucujide f.

* The name Aphodius duplex given above (p. 87) has been previously applied by Leconte to a North-American

species of this genus ; I now propose to change the specific name to opisthius.

+ In further elucidation of the group of Saprosites, comprising the bark-living species, I append diagnoses of

the following curious forms :—

About eighty species of this genus have been described, all of uniform black or

rufo-piceous colour, and, as Dr. Horn justly observes, in many cases difficult to discri-

minate. Although characteristic of the American fauna, tropical and temperate, the

genus is not wholly restricted to the New World, several species being recorded from

widely distant regions, such as Abyssinia, the Malay Archipelago, and Australasia.

Most of the species obtained by Mr. Champion were found in sandy places, especially

about the banks of streams.

Notwithstanding its distinct facies A. castaniellus cannot be regarded as more than

a variety of A. liogaster, examples intermediate in one or other of its characters

being found in the same localities.

I have some hesitation in separating A. liogaster from A. strigatus (Say), in which

also the sexes differ in the form of the hind angles of the thorax; but on comparing a

large series with the numerous examples of A. strigatus before me (including several from

Texas and more northerly localities), it shows a constant difference in its rather smaller

size, deeper elytral strie and more convex interstices, and smoother ventral segments.

The sculpture of the head and thorax varies considerably, but preserves the same

general character, the punctuation on the thorax being always sparser than in A. eribri-

thorax, larger and smaller punctures being intermingled, and spaces on the sides and

sometimes near the base being quite smooth. The humeral callus and sides of the

elytra are also quite free from punctures.

(Champion).

In the punctured interstices at the sides and apex of the elytra, this species agrees

with Von Harold’s description of 4. stercorator (Fabr.); but I have not seen any

examples from Brazil, which country he includes in the range of his A. stercorator,

and there can be little doubt that his description refers to a rather larger species,

described further on as A. strigicauda. Among the very numerous examples I have

96 LAMELLICORNIA.

examined of A. cribrithoray there are some which nearly bridge over the difference

between it and A. strigatus and A. liogaster.

I have adopted the name given to the species in the Sallé collection.

4. Atenius strigicauda. (Tab. VI. fig. 24.)

The examples from the above-named localities, which I have examined and found

closely to agree, appear to be referable to Von Harold’s A. stercorator, which unfor-

tunately is totally different from the Fabrician species, as proved by the type still in

fair preservation in the Banksian collection at the British Museum. The present

species was carefully and well described by Von Harold, with the exception, if I am not

mistaken, that he overlooked the fine strie on the sides of the elytral interstices near

the apex; these striz exist in all the specimens I have examined, and present a feature

of some interest, as they are further developed in a series of allied species, and thus

display in an incipient form an important group character. In all its other characters the

species scarcely differs, except in its greater size, from the male of our A. eribrithoraz.

A. ‘stercorator (Fabr.) belongs to the same wider group as A. strigicauda (thorax —

margined at the base and clypeus rounded on each side of the anterior sinuation) ; it is

a species of about the same size (6 millim.) and shape, but it is of a dull sooty-black

colour, with the thorax closely and evenly punctured throughout, and the elytra not

crenate-striate but sharply sulcated with an elegant catenulate-punctuation in the

bottom of the furrows and the interstices convex, almost culminated. A remarkable

distinguishing character of the species is a series of tubercles or denticulations at regular

intervals on the inner side of the four hind tibie. Besides the Fabrician type captured

by Sir Joseph Banks at Rio Janeiro on Cook’s first voyage, the British Museum possesses

a second example taken by Darwin in the same locality, during the voyage of the

‘Beagle.’ I have seen other examples from Rio Janeiro in Mr. A. Fry’s rich collection. -

We figure an example of 4. strigicauda from Cordova.

evenly punctured ; the elytral interstices convex, and behind gradually more carinated

with conspicuous punctures on each side; the scutellum concave, with asmooth carina

down the middle; and the outer apex of the four hinder tibie produced into a long

acute spine. ‘The species is possibly the Euparia atramentaria, Erichs., of Peru, but the

absence of mention of the sculpture of the scutellum leaves the matter in uncertainty.

6. Atznius euglyptus.

A little larger and more convex than A. strigicauda, and with much more strongly

Closely allied to A. perforatus and A. euglyptus, but the elytral interstices throughout

acutely cariniform, and the surface beset with erect bristles. In consequence of the

narrowed interstices the lateral scored line on the side of each, seen in a rudimentary

form in most of the allied species, has here become a broad furrow separated from the

stria proper by a lesser carina. ‘The scutellum has in the middle of the base a large

triangular opaque fovea. ‘The base of the thorax is not margined, but in some examples

a fine impressed line is seen on the deflexed edge in the middle.

I can detect very little difference of form which can be supposed to be sexual. The hind

angles of the thorax are in all examples rounded. ‘The erect grey bristles of the elytra

are numerous only over the apical half. The species comes nearest to A. hirsutus, Horn,

the emargination of the clypeus and the distinct angle on each side being very similar

in both; but the head and thorax are much more sparsely and finely sculptured.

In its narrow sublinear form this insect approaches the species of Section II. The

outline of the clypeus is different from that of A. strigatus and its allies, for although the

sides of the emargination are not pointed, they are slightly angulated and not broadly

rounded. A. gracilis may be distinguished from other small and narrow species by

the more or less distinct dorsal furrow of the thorax.

Evidently allied to A. steinheilt, Harold, from Colombia, but differing in the peculiar

sculpture of the head, the close punctures of the vertex running into fine longitudinal

ruge on the forehead and leaving only the margin of the clypeus a little smoother,

with a few transverse granular wrinkles. The sculpture of the elytra would agree

pretty well with the description of A. steihezl if we take the “ tief und ziemlich breit

gestreift” of Von Harold as meaning the superficial appearance only; for the strize

proper are narrow, and it is only the elevation of the outer side of the interstices into

ATANIUS. 101

narrow carinee which produces the effect of broad striz, part of each interstice being

depressed together with the striz.

We figure a typical example from Cordova.

Differs from A. scalptifrons, to which it is very closely allied, by the humeral spine

of the elytra being, as usual in the group, very short. The carine of the interstices

are, besides, much higher and narrower and granulated, the remainder of each inter-

stice, with its feebly carinated striz, forming thereby broad furrows.

parts being quite smooth in both species. The sculpture of the elytra differs from

that of P. celatus only in the striz being much deeper. |

Resembles also the P. guinque-plicatus, Horn, but the elytra are more ovate and the

thorax has not the five equally impressed sulci of that species.

Herr Hoge obtained a very large series of examples at Vera Cruz, which offer scarcely

any individual variation. Two examples also were captured at Tapachula on the

Pacific slope. |

Closely allied to the South-European P. sabulosus, Muls. It has the same general

form and colour, and structure of legs, and also a similar sculpture of the head and

thorax; but it is very much smaller; the vertex for a wide space is perfectly smooth

and polished ; the punctures of the thorax are smaller and more widely spaced; and

the punctures of the elytra are confined to the bottom of the neatly-ploughed strie,

scarcely crenating the sides of the interstices.

Very closely allied to P. micros. Smaller (14 millim.); colour reddish-testaceous, the

head and thorax castaneous with paler margins, and the latter having one lateral trans-

verse groove only. In the identification there is a difficulty in the phrase used by

Chevrolat, “elytris striato-punctatis,” as this does not accurately express the sharply

catenulate-punctate strie.

6. Psammodius integer.

Oblongus, convexus, glaber, nitidus, castaneus; capite lato, verrucoso, occipite levissimo ; clypeo late et minus

profunde triangulariter emarginato, utrinque angulato, acuto; thorace sat magno, lateribus arcuatis,

postice magis quam antice angustato, angulis posticis nullis, supra mediocriter punctato, punctis minutis-

simis intermixtis, sulcis trausversis nullis foveaque sola prope angulos anticos, lateribus medio subleevibus,

convexis ; elytris fortiter crenato-striatis ; carina mesosterni elongata.

Hab. Muxico, Vera Cruz (Hége).

This species connects Atenius with Psammodius. It differs entirely from the former

by its robust broad hind tibiz (subserrate and setose along their outer edge and not

prolonged into a spine at the outer apex), by their robust spurs (which, however, are

obtusely pointed at their apices rather than spatulated),and by the short tarsi, in which

the basal joint is very much broader than the others. On the other hand, the head

and thorax are constructed as in the second section of Atenius, the latter showing no

trace of the transverse furrows of Psammodius except a well-marked and large fovea

near the anterior angles.

The two varieties described agree in all structural points with 4. colombianum, but

differ from it greatly in their denser and coarser punctuation, especially of the upper sur-

face. Westwood describes the head and thorax as smooth and shining: in a Venezuelan

example I find them sprinkled with minute points, denser, however, on the anterior

part of the head. Flat scales in the punctures are visible, at least on the elytra, in

the typical species; but they are very conspicuous, and give a tawny-brown tint to

the whole body, in the var. sguamatum.

A genus of very wide distribution, but the species are nowhere abundant in individuals.

The majority inhabit the temperate zone of both the Eastern and Western hemispheres ;

the remainder being sparingly scattered over South America, and tropical Asia and

Africa. Twenty-five species have been described ; but, as is evident on reading

Dr. Horn’s excellent analysis of the North-American forms, it is impossible to discrimi-

nate them without close attention to the sexual differences and various peculiarities of

Hah. Mexico + (Sallé).

I refer an example in the Sallé collection to this species, as it agrees with Westwood’s

description in size (9 millim.) and sculpture; but if it represents the same species it must

be the opposite sex, as it shows no traces of the two tubercles between the Gyiess menline

forehead is concave, and the arcuated and thickened rim of the clypeus is terminated on

each side by a large tubercle; the epistoma below im front is flattened, and also has a

thickened rim on its front margin.

Hab. Mexico, Presidio (Morrer). One example.

Differs from all other species here enumerated in the apparently double clypeus,

which results from the true elypeal margin being not at all thickened, or vertically

declivous in front; the epistome is consequently nearly on the same level, and having

an equally distinct and similarly arcuated anterior margin it looks like a duplication of

the clypeus proper. A similar structure seems to be exhibited by the North-American

species O. ulkei, O. simplex, and O. musculus, the last mentioned having, however, a

thickened margin.

the hind femora, One specimen differs in the punctuation of the elytral interstices

being less dense and the surface consequently more shining. The much thickened

clypeal margin is strongly arcuated, scarcely hemi-hexagonal ; its front face is rather

high and subvertical, and at its foot is flattened out into what I term the epistome, to

the very slightly thickened anterior margin of which the labrum is articulated.

process at the inner apex of the anterior tibie appears not to exist in Westwood’s

species, judging from the figure and description.

About forty species of this distinct and very remarkable genus have been described.

It is distributed over the tropical zones of the three great continents, but is much more

numerously represented in America than in Asia or Africa, and extends there into

the south temperate zone as far as Buenos Ayres. The North-American species referred

to it by various authors belong to a different genus, Bradycinetus, Horn.

These insects are found flying close to the ground amongst low herbage just before

dark, and are often attracted to light (Champion).

The armature of the thorax can be best understood on referring to Westwood’s

figure of A. pholas, an allied Colombian species. The carinze which limit the deep

dorsal concavity are flexuous both vertically and laterally ; about the middle they

rise highest and there form a large triangular tooth, each slightly curving towards its

vis-a-vis, and behind they curve sharply inwards. In A. pholas the opposite carinz

behind meet at the dorsal line, but in A. fissicornis they stop far short of it. The

strong tooth or spine rises vertically from the middle of the anterior margin as repre-

sented in Westwood’s figure, but in well-developed males it is higher, reaching nearly to

the level of the thorax, and broad and cleft at the apex; in males of lesser development

(or females ?) the spine is shorter and pointed as in A. pholas and A. trituberculatus

(Klug), and a little removed from the margin. The carine in the same individuals

differ in continuing, behind, parallel to each other, and emit a small branch inwardly

towards the dorsal line, exactly as represented in Westwood’s figure of A. reichei; this

latter is doubtless the female of a species allied to A. fissicornis, in which the sides

of the clypeus are obtuse. The anterior tibiee have six teeth.

A male specimen from Mexico is figured.

granules without punctures or rugosity *

three, viz. the number of teeth on the anterior tibie and the larger or smaller impunc-

tate space on the hind slope of the large and broad thoraeic excavation, prove, on the

examination of more abundant material than he possessed, to be of no specific import-

ance. As the localities above recorded show, all three forms occur in the same places

from Mexico to Bahia; and the close examination of about forty examples from the

various localities reveals no difference whatever of colour, form, or sculpture between

examples which otherwise differ in the number of the tibial teeth. Specimens, further,

occur in which the uppermost tooth is shown in a transitional state, 7. ¢. instead of a

distinct saw-like toothlet it is more or less rounded. The granulation of the hinder

slope of the suboval concavity of the thorax varies in the male according to its degree

of development ; and in the female, which is very much rarer than the male, the whole

of the concavity is uniformly granulated, besides being much shallower than in

the male.

The size varies from 8 to 13 millim.

has a wider range than Athyrews, being numerously represented in warm temperate

comparatively small number.

More than a hundred species are known of this familiar genus, so eminently charac-

teristic of the Insect Faunas of the north temperate zone of both hemispheres. It passes

into the northern tropical zone both in America and in Hastern Asia; but it is doubtful

if it is found so far south as Celebes, as recorded in the distribution of certain Japanese

species. The locality “Peru” found by M. Jekel to be attached to specimens in Mr.

Saunders’s collection appears to have been erroneous, the insects being Mexican ; and

a species (G. lateridens) recorded as from Chili proves to be European (C. subarmatus).

The typical specimen in the Sallé collection, a male of minor development, differs

much in the form of the thorax from corresponding individuals of G. fronticornis «

this part is very much broader, chiefly owing to the explanated lateral margins;

from the subangular dilatation in the middle it is greatly narrowed nearly in a straight

line to the anterior angles, and less, but still considerably, narrowed to the hind angles.

The other characters mentioned by Jekel—the blue colour, the interrupted basal margin

of the thorax, and the deeper and broader elytral strie—are found in indubitable

examples of G. fronticornis.

From the description given by Jekel of the general form (taken from a single

example, a ¢ minor from the Mniszech collection), the shape of the thoracic protuber-

ance, and the outline of the thorax, I think there is good reason to conclude that

the specimen above described belongs to the same species, which is thoroughly distinct

from G. fronticornis.

On examining the type of G. falsus, kindly lent by Dr. Sharp (the possessor of the

Saundersian collection of Lamellicornia), I find it to differ from the few examples we

have of G. sall@i exactly as stated by M. Jekel; but the differences are evidently only

individual, and the specimen is doubtless from Mexico, and not from Peru, as

labelled. .

vidual peculiarities from Mexican specimens of G. viridi-obscurus of the same sex.

The chief difference adduced by the describer, viz. the fuliginous antennal club, is due

simply to a coating of dirt on that organ. Dr. Sharp informs me that there are other

instances of specimens inadvertently labelled Peru instead of Mexico in the Saundersian

collection.

I class under this species numerous examples of a form smaller and relatively shorter

male does not differ from that of G. viridi-obscurus in the teeth of the under surface

of the fore tibie.

much-worn female, though presenting a distinct anterior tooth on the underside of

the anterior tibie.

G. guatemalensis belongs to Jekel’s subgenus Phelotrupes, which, in his Monograph,

contains only Indian and Japanese species.

I cannot find that Dr. Candéze ever described this singular species, which he

distributed to his correspondents many years ago under the name I have adopted.

Mr. Champion met with one example only, a small male. As the middle leaflet of the

antennal club is entire round its edge, and the apical tooth of the male anterior tibie

is broad and bifid, though to an exaggerated degree, the species, I presume, would

belong to Jekel’s subgenus Cnemotrupes.

The middle leaflet of the antennal club has part of its edge emarginated ; the species

therefore belongs to Jekel’s Division IJ. It is apparently allied to the European

G. (Canthotrupes) douei, Gory, the margin of the gene, or “ canthus ocularis,” being

bidentate in the same places as in that species, though the prominences are not nearly

so large. The mandibles also do not present the extraordinary form they have in

G.douet. I assume that the two examples examined are males.

CLQLOTUS.

Preudhomme de Borre, Catal. des Trogides, p. 12 (1886).

Acanthocerus, Germar, loc. cit. p. 181 (nec Macleay).

M. Preudhomme de Borre enumerates, in his ‘Catalogue des Trogides, twenty-

six species as belonging to this genus. With one exception (a species from Penang)

they are all from America, where they are spread over the temperate and tropical

zones from the United States to Chili.

Von Harold in his Col. Hefte, xii. p. 28, enters fully into the reasons which induced

him to change the name given to this genus by Germar in his monograph of the group.

The characters given by Macleay of his genus Acanthocerus, although containing some

errors, leave no reasonable doubt that he had in view the same generic form as that

on which Germar constituted his Spheromorphus. The inconvenience attending this

displacement of names is perhaps lessened by Von Harold having retained the name

Cleotus for both Germar’s genera Cleotus and Acanthocerus (nec Macleay), which

appear to offer no essential difference.

The spherical Trogide are generally found by beating bushes containing dead twigs,

from which they readily drop in the coiled-up state, sometimes in considerable

numbers, into the inverted umbrella. It was in this way that Mr. Champion obtained

his extensive series of the group. They feed on dead fungoid matter and galls. I

On examination of a large series from various localities this species proves to vary in

all those points of colour, bloom of surface, and sculpture on which Germar and

Erichson relied in separating it into five, for I see nothing in the description of

Erichson’s A. puncticollis from South Brazil to merit its specific separation from the

rest. The character derived from the carinated interstices of the elytra towards the

apex seems to be a little more constant than the sculpture of the head and thorax,

which is variable among examples from one and the same locality. In nearly

all the northern specimens the longer exterior carina is sharp and clear of indenta-

tions. This is the chief distinguishing feature in Germar’s description of C. glo-

bosus. I find it more pronounced in the Jalapa examples captured by Hoge than

in specimens of the typical C. globosus from Louisiana. The Cordova specimens in

the Sallé collection are somewhat different, and show a tendency towards C. sticticus

and C. macleayt in the laterally crenated and wavy line of the same carina. Guatemala

examples all show a more or less wavy carina, and in those from Chiriqui this feature

is generally a little more pronounced; but I find that it varies even in South-Brazilian

examples of C. macleayt. ‘Thus it must be held doubtful if the five species of Germar’s

Monograph can be maintained even as constant local varieties. Further material from

South-American localities is required to decide the question.

The variety, of which three examples only were taken by Mr. Champion in Guatemala,

agrees precisely with North-American specimens of C. aphodioides in its oblong form

and in the sculpture of its surface; the sides of the thorax have three similar polished

elevations, and the apex of the elytra six carine, viz. three parallel to the suture, and

three to the lateral margin, the broad sulci between the latter being marked with fine

chain striz in elegant pattern. In the variety the elytra have subrectangular shoulders,

and a very narrowly dilated margin, which for a short space near the shoulder is con-

spicuously, though finely, serrated. The colour of the elytra is brilliant brassy, almost

golden, and the underside of the body wit h the femora is reddish.

Of the same oblong form as C. aphodioides; brassy-black, with greenish-bronze and

(vertex excepted) closely punctured; clypeus broadly rounded, the edges reflexed ; gene

triangular, sublobate. Thorax transverse, quadrate, slightly narrowed anteriorly, the

sides nearly straight, the hind angles rectangular, submarginal impressed line entire,

near the anterior angles broader, its inner edges raised and thickened; surface finely

and not very closely punctured, becoming nearly smooth behind, the lateral border

having a large oblong depression, thickly and finely flexuous-strigose, and without

polished elevations. Scutellum smooth, at the base a very few punctures, and within

the apex a shallow punctured fovea. Elytra with rows of short linear punctures not

impressed in striz, the lateral margin near the shoulder with 3 or 4 serrated denticu-

lations, the apex as in A. aphodioides with six carine, the interstice 2 (from the suture)

being carinated to the apex, the interstices 8 and 4 having very short carine, and 6, 9,

and 11 having carinz successively increasing in length, the broad sulci between the

three having fine wavy strie forming a chain-like pattern. Possibly only an extreme

variety of C. aphodiotdes.

This apparently common Central-American species varies much in colour and

sculpture both of surface and of the flattened outer side of the posterior tibie, and

rather less so in the tuberculation of the apical area of the elytra. In all its varieties

it is distinguished by the broad, but very shallow, sinuation of the clypeus. As to

colour-variation, the brilliant red-coppery examples seem to be almost confined to

BIOL. CENTR.-AMER., Coleopt., Vol. IL. Pt. 2, November 1887. RR

122 LAMELLICORNIA.

Mexico, where dark-bronzed hues are the exception, whilst the reverse is the case in

Guatemala, where at Capetillo, judging from the very numerous specimens taken,

bronze-black is the general colour ; Capetillo examples are, moreover, distinguished from

the Mexican form, with very few exceptions, by the strie of the outer side of the

posterior tibie being much abbreviated, leaving a large apical space smooth or sparingly

punctured ; but there are all gradations in the extent of the smooth space. At Cerro

Zunil the prevailing colour is again different, the elytra being very dark ereenish-

bronze, nearly black, and the head and thorax dark coppery; this form, which I

propose to call C. seywnctus, is also distinguished, but not quite in all the examples, by a

slight peculiarity of sculpture at the elytral apex, the acute submarginal carina not being

hooked behind, and also by the finer punctuation of the whole surface. As to the

general punctuation, it varies greatly both in strength and density, as in most of the

species of the genus, but the variation in this respect does not correspond with other

differential characters.

The sculpture and tuberculation of the apical area of the elytra consists (1) in an

oblique row of about five oblong tubercles preceding an apical depression, the outer-

most of which is a short, but sharp, carina on the tenth interstice, (2) in a long

submarginal carina (on the twelfth interstice) sharply hooked at its apex, (3) in a

series of two or three tubercles, sometimes oblong, sometimes conical, and sometimes

connected as a wavy carina, on the apical part of the second interstice (i. e. the one

following the sulciform sutural stria), and (4) in a variable number of small rounded

warts on the intermediate space. ‘his apical space is otherwise scored with sharp

striz, the interstices of which are flat and smooth.

7. Cleotus strigilateris.

Hab. Mexico, Cordova (Salié).

The numerous strongly elevated carine and tubercles of the apical area of the elytra

distinguish this species from C. infantulus and C. excisus, the latter having the usual

carinee very faintly elevated, and the former three continuous carine, and being further

distinguished by the entire rounded edge of the clypeus. In one of the two examples

the apex of the hindmost tibiz is very widely and strongly emarginated, and the inner

angle (which carries one of the spurs) is very much shorter than the outer; in the

other specimen the two spurs are nearly on the same level. ‘The apical cross section

CLGOTUS. 123

of the tibiz is narrow-oblong, and subacuminated at the upper (outer) end. The hind

tibize are much more triangular and broader at the apex than in C. infantulus.

Var. Capite thoracis disco scutelloque basi punctulatis.

Hab. Mexico, Cordova (Saldé).

Similar in form and closely allied to C. sinwatus, var. sejunctus; but much smaller,

and distinguished by its perfectly smooth and polished head, disc of thorax, and

scutellum, as well as by the absence of distinct tubercles from the apex of the elytra.

The apex of the clypeus is distinctly emarginated, and a small broad tooth is perceptible

on each side of the emargination. ‘he thorax is finely margined throughout, the hind

angles imperceptible, and the flattened sides marked pretty uniformly with fine curved

scratches. The elytra have the long submarginal carina and the short inner carina

on the tenth interstice fine and very little elevated; there is no tubercle or carina in

the apical area, the sutural stria is deep and broad, and the interstices on each side

are equally elevated, straight, and smooth; the margin near the base is finely serrated.

The hindmost tibie are moderately prolonged at the apex, and their outer surface is

marked with a few longitudinal strie; the apical truncation is rather narrow.

The var. from Mexico agrees precisely with the numerous Senahu examples, except

in the fine punctuation of the head, thorax, and base of the scutellum.

and smooth convex interstices on each side of the sutural sulcus; in C. bidens, how-

ever, it differs from that species in having two carinated interstices (one of which is

the usually short carina of the tenth interstice, which is here prolonged to the apex)

between the convex interstices and the long submarginal carina. The apex of the

hindmost tibiz is more compressed than in the allied species, and the apical truncature

forms a narrow oblong, thus approaching the Acanthoceri.

Mr. Champion obtained a large number of specimens at Bugaba. Three examples

from Parad in my own collection offer no difference.

One example only was obtained by Mr. Champion at Bugaba, differing in its smaller

size and feebler sculpture from the typical form from the Amazons. The example

from Irazu is more characteristic. The species differs from C. bidens in the simply

angulated and smooth clypeus, the more distinct hind angles of the thorax, and the

smooth external face of the hind tibie. The sculpture of the apex of the elytra is

nearly the same.

Central-American specimens vary a little in the punctuation of the head, and in the

form of the apical angle of the clypeus, the angle being sometimes entire, and sometimes

slightly notched; but these differences do not correspond with the variations that

exist in the strength of the punctures of the elytra, which, according to Germar, also

varies much in Brazilian examples. Examples with triangular clypeus and punctured

head with round polished frontal tubercle agree in these respects exactly with C. viridi-

pennis, from which C. nitens in all its varieties differs in the sculpture of the apical

part of the elytra. In the latter the elytra have their apical portion entirely free from

tubercles and sharp carine; and the interstices are mostly broad and slightly convex, and

separated by single, sharp strize, which become longer from the sutural region towards

the lateral margin. C. nitens is also a larger insect than C. viridipennis.

obtusely angular. or subproduced at the apex, shows no signs of emargination, the

According to the description this species is very similar in form, colour, and sculpture

to C. viridulus; but the size (24 millim.) is much less, and the phrase “bords

latéraux (of the thorax) légérement sinués,” does not at all agree, neither can I reconcile

the description of the apical sculpture of the elytra with C. viridulus.

Preudhomme de Borre enumerates twenty-eight species as belonging to this genus.

Four are from Borneo and the neighbouring islands, the rest from America.

1. Acanthocerus eulampros. (Tab. VII. fig. 23.)

A. polito (Hrichs.) affinis; splendidissime sneus, corpore subtus rufescente; clypeo basi, vertice scutelloque

lateribus sparsim punctulatis; thorace stria antico-marginali medio anguste interrupta et versus angula

margini approximata; elytris disco subtiliter striato-punctatis, apice levi, stria marginali et suturali prope

apicem impressis; tibiis posticis dichotome oblique striatis.

Long. 7 millim.

Hab. Nicaragua, Chontales (Belt); Panama, Volcan de Chirigui 2500 to 4000 feet

(Champion).

Distinguished from A. politus by the finely punctured base of the clypeus, and the

four or five abbreviated rows of small punctures on the disc of each elytron. The

sutural row of punctures (which graduate into a deep stria towards the apex) does not

reach the base of the elytra. ‘The base of the thorax is rounded, and there is not the

slightest trace of posterior angles, but the margin is slightly depressed on each side near

the scutellum, and the inner side of the depression is slightly tumid. The lateral margin

of the elytra in the place where the knees of the middle legs fit {in the rolled-up state)

is arched and sinuated. A specimen from Chiriqui is figured.

2. Acanthocerus humeralis.

Spheromorphus humeralis, Erichs. in Germar’s Zeitschr. fiir Entom. iv. p. 116°.

Hab. Panama, Bugaba (Champion).—Sourtn AMERICA, Para },

Two examples, differing from the type form in the more prominent tubercle on the

outer side of the basal depression on each side of the thorax and the corresponding

more prominent shoulders of the elytra, a difference probably sexual. Von Harold in

ACANTHOCERUS, 127

his remarks on the South-Brazilian A sesquistriatus (Col. Hefte, xii. p. 35) says that

Erichson’s type specimen of A. humeralis has a short submarginal elytral stria like

A. sesquistriatus, t. e. a sharply incised stria. If this is really the case, the reference

of the present species to A. humeralis is wrong. But I suspect Von Harold’s is a

mistaken observation. No mention is made of the short stria in Erichson’s description,

which otherwise (with the exception of the punctured apex of the scutellum) agrees

with specimens taken by myself in the country from which his examples were derived.

8. Acanthocerus relucens. (Tab. VII. fig. 24.)

A, seriato (Erichs.) affinissimus ; differt vertice et scutello levibus elytrorumque interstitiis apicalibus alternis

Hab. Muxico, Jalapa (Hoge); British Honpuras, Belize (Blancaneaua).

Sufficiently distinct from A. seriatws (Erichs.), a species of the Amazons valley, by

the characters above mentioned. ‘The depression of the hind margin of the thorax on

each side of the scutellum is common to both species, and in some examples ( @ ?) has

a distinct tubercle on the inner side; but the apical marginal stria is finer and nearer

to the margin, though variable in this respect. ‘The scutellum has a few punctures at

the base on each side. The rows of shallow, oval punctures on the elytra are variable

in strength and number; the sutural stria, which as usual is deeply impressed at

the apex, becomes a similar row before the middle, and continues as such to the base ;

the six short sulci of the apex increase in length from the suture outwards, but the

longest does not reach the middle, and the smooth interstices are alternately moderately

elevated, not sharply and greatly raised as in A. sertatus. The hindmost tibiz externally

are marked with arcuated scratches, mostly isolated, and the scratches do not form a close

reticulation as in A. seriatus. A Chiriqui specimen is figured.

4. Acanthocerus vicarius.

flab. Mexico, Cordova (Sallé), Jalapa (Hoge); Britise Honpuras, Belize (Blan-

caneaux); GUATEMALA, Cubilguitz, Senahu, Cerro Zunil, Las Mercedes (Champion).

A large number of examples. Belongs to a group of smaller species, widely distri-

buted in Tropical America, in which the stria accompanying the fore margin of the

thorax is deep and continuous, and the upper surface more or less thickly punctured.

The present species agrees with the South-Brazilian A. semipunctatus in the puncture-

rows of the elytra scarcely reaching the base, and not being impressed at the apex or

forming there two or more sharp strie; but it seems to differ in the greater regularity

of the rows, the punctures of which in A. semipunctatus are in many places out of line,

and the rows consequently confused; in A. vicarius the rows are nearly straight, except

the second, third, fifth, and sixth towards the apex. The head (except the vertex) is

thickly covered with large, separated punctures, which are sometimes equally strong

throughout, and sometimes finer on the forehead than on the clypeus. The thorax differs

in form from that of the more typical Acanthoceri in having distinct, though rounded,

hind angles; it is punctured almost as strongly on the disc as on the sides, but there

is a space in the middle of the lateral margins, a vague dorsal line, and a round spot

on each side of the disc smooth and polished; the punctuation, however, varies in

strength in different individuals, the same as it does on the scutellum.

5. Acanthocerus micros.

et irregularibus, striis exterioribus versus apicem fere continuis.

Long. 24-3 millim.

Hab. Mexico, Jalapa, Misantla ({égqe).

The chief distinction between this species and A. semipunctatus is furnished by the

widely different sculpture of the hindmost tibie. Germar describes this sculpture (in

A, semipunctatus) as “ Runzeln welche durch zusammenfliesende punkte entstehen,”

which Von Harold (Col. Hefte, xii. p. 35) further explains as “bilden die Runzeln

ae eine dichte aus kurze halbkreisen bestehende punktirung.” This perfectly

well suits our A. vicarius as wellas A. semipunctatus; but A. micros shows in the tibial

sculpture no trace of small semicircles, the sculpture consisting of fine longitudinal partly

dichotomous and partly confluent lines. The approximation of the punctures almost

(but not quite) to the formation of linear stria, in many of the rows at the apex of

the elytra, also distinguishes the present species.

6. Acanthocerus rotundicollis. (Tab. VII. fig. 25.)

Hab. Panama, Volcan de Chiriqui (Champion). One example only.

Differs from all other Acanthoceri known to me by the convexity of the head being

continued to its edges; and also by the form of the thorax, the sides of which are cut in

nearly a straight line, and obliquely from opposite the outer angle of the scutellum to

near the anterior angles, at which point the thorax is at its greatest width. On each

side of the basal margin of the thorax, near the angle of the scutellum, is a small

but conspicuous concavity. In the way the single example is mounted I cannot examine

the sculpture of the exterior face of the hind tibie.

An interesting generic form, connecting three families placed wide apart. in Lacor-

daire’s system, viz. Hybosoride, Aclopide, and Glaphyride; and demonstrating that

the mouth-structure (especially the free bilobed ligula) is more to be relied upon than

the position of the abdominal spiracles as indications of natural affinity in this portion

of the Lamellicorn series. The legs (with the exception of the male developments) are

those of the typical Glaphyride, the absence of transverse tibial carine distinguishing

this genus from Aclopus, and approximating it to Glaphyrus, as also does the cupuliform

club of the antenne. The form of the metathoracic episterna and epimera is that

of Celodes in the Hybosoride; and the shape and relative position of the clypeus,

labrum, and mandibles are the same as in Aclopus, Hybosorus, and not essentially

different from the Glaphyride.

The abdominal spiracles are microscopically small; with a powerful lens three are

visible on the connecting membrane, and a posterior one is just perceptible on the edge

of a ventral segment.

Burmeister’s description, drawn up apparently from a single example, fails to convey

a correct idea of the colours and markings of this elegant species. ‘The pattern of the

elytra in most examples consists in two or three black longitudinal lines with two large

black spots in each interspace, the ground-colour varying from light greenish-ashy to

orange-fulvous. The numerous varieties diverge from this typical pattern in opposite

directions :—1, towards melanism, the black spots and stripes being fused together, at

first leaving pale spots on a dark ground, and in the extreme form the elytra becoming

wholly velvety-black; 2, towards lack of black pigment, the black lines and spots

becoming attenuated, and more or less vague; 3, until at length the elytra are

uniformly ashy or fulvous. The thorax is generally, as Burmeister describes it, ashy

with a broad discoidal black patch, but varies in the black central spot being dissolved

into two vittee, or (in the unicolorous pale form) disappearing altogether.

I can detect no sexual difference among the numerous examples either in the abdomen,

legs, or antennal club. The anterior tibie are in all tridentate. We figure a specimen

sideways the surface of the body appears to be minutely and closely granulated. The

ashy-white specks are often ill-defined, but in other examples the white spots are large

expands into a large central patch common to both elytra, or diminishes to two bands

of dusky spots; or the dark spots are absent and their companion cinereous spots only

present. The majority of the specimens are, however, uniform greyish-ochreous. The

elytra have a few very short stiff bristles arranged in rows; the under surface is covered

with small oval greyish scales implanted at short distances from each other.

Distinguished from Ceraspis, according to both the authors above cited, by the

uncleft tarsal claws. Blanchard erroneously placed /&. cornuta (Ceraspis rufipes,

Burm.), which has bifid claws, at the head of the genus, guided doubtless by the

similarity of general form (the numerous spines of Faula being greatly elongated) and

the subglabrous surface. . cornuta and its allies being excluded, the genus is not well

demarcated by facies from Ceraspis, and is by some authors considered only as one

of the groups of that genus. So far as at present known, Faula is restricted to the

A characteristic American genus, spread over the temperate and tropical regions of

the continent, though rare or absent in the plains near the equator. Between thirty

and forty species have already been described. In studying the very numerous species

from our Fauna I have carefully attended to the secondary sexual characters of the

nale (discovered by Horn and Kirsch); but have found that, like all other characters

in the genus, they are subject to variation, and must be used with caution. The

development of the postcoxal spine, for example, though its normal form seems to be

specific, is subject to abrupt change in the same species; and the number of ventral

sete on each side the middle line of the abdomen varies, though, making allowances for

some variation, they form a very good specific character. The singular and abrupt

modification in the pubescence of the thorax in the females of some of the species,

described below in their places, and the many variations in colour and amount of the

pile, both above and beneath, show how useless descriptions of species in this genus

must be unless founded on a good series of examples.

Scarcely more than a local variety of MV. uniformis. Like that species and the

spine, broad and emarginated, or even bifid, at the tip; and a numerous group (3-9) of

long and very strong (almost spinous) tawny bristles on each side of the second to the

fifth ventral segments, besides similar irregular spines at the apex of the fifth and on

the sixth, and also on the middle of the metathorax. ‘The pile of the upper surface is

more compact than in any other known species, and light ashy (not tawny) in colour.

As in I. uniformis, the integument beneath is black.

Burmeister seems to have regarded this and the preceding (MM. variipes) as one

species; at least his description applies to both. Castelnau’s brief description of

M. angustatus applies well to M. mexicanus; and M. cinereus, Blanch., might be taken

to be the same species, were it not for the locality, Peru.

There is nothing in general form or structure to distinguish M. mexicanus from

M. variipesand M. uniformis. It differs, however, in never being of a uniform pale ashy

colour above, in the integument (especially of the thorax) being steely-blue, and in the

laid pubescence being finer and sparser. A general bluish-grey tint prevails over the

surface, varied by a tawny area at the base and shoulders of the elytra. ‘The striz of

the latter are generally left bare of pubescence; but they are sometimes covered; the .

suture and the outer margin are nearly always blackish. ‘The thorax has a distinct

dorsal furrow. The anterior tarsi and the antennal club are black; the four posterior

tarsi are rather darker than in Jf. wniformis—black, with the bases of the joints reddish,

and ringed with cinereous hairs.

Distinguished from I. uniformis and its allies at first sight by the darker reddish-

ochreous colour, and the black tibize and tarsi, the latter unicolorous. The clypeus is

narrower and rather longer than in those species, and the converging sides are straight ;

the fore margin is truncated, with blunted angles. The pile on the thorax is longer

and adpressed, each hair in some examples being many-branched; that on the elytra

consists of very short, slanting, separate and simple hair-scales, but sometimes of longer

and much denser hairs, the side margins having a broad band nearly denuded, and of

the reddish-tawny hue of the elytral integument, and the base a few longer erect

bristles. .

The variation in the length of the postcoxal spine, and in the colour of the ventral

bristles in the male, is noteworthy.

Macrodactylus lineatus, Chevr. Col. Mex. Cent. i. fase. 4. no. 48°.

Hab. Mexico, Vera Cruz}, Cordova, Toxpam (Sallé), Jalapa, Tapachula in Chiapas

(Hoge).

In general form, narrow trapezoidal clypeus, and integumental colours, JM. lineatus

does not differ materially from M. submarginatus and M. sericeicollis. ‘The denuded

parts of the elytra are, however, in some examples not unicolorous tawny-red, but tend

to become black towards the sides and apex. In the paucity of the ventral sete of the

male it also agrees with these species ; the number of setee on each side is two, on some

segments only one. It differs in the elytra having a broad lateral border, the suture,

and three slightly raised costee on each (the 3rd, 5th, and 7th interstices) denuded ; the

remaining, and broader, interstices, the thorax, and the hinder part of the head are

clothed with moderately short adpressed yellowish-ashy hairs. ‘The antenne are

wholly red; the legs red, with all the tarsi and the apex of the posterior tibie black.

An example from Cordova is figured.

Similar in colour to W. costulatus var. rufipennis; but distinguished from it by the

much more riumerous and longer spiny bristles on each side of the ventral segments,

and by the cinereous rings of the hind tarsi. In the numerous male ventral spines, the

ashy-ringed hinder tarsi, and the rather short trapezoidal clypeus, the species betrays

an affinity to J. variipes and its allies.

The small examples are from North Mexico (Durango). In Guatemalan male examples

he elytra are silky fuscous at the apex. We figure a specimen from Las Vigas.

iv. 2, p. 42 (1855) ; Lacordaire, Gen. Col. ii. p. 247 (1856).

An exclusively American genus, like Macrodactylus, but apparently restricted to the

tropical zone of the continent. Upwards of sixty species have been described, but as

little attention has been paid to the extraordinary variation in the colours and markings

which the species present, it is probable that many of them are not valid.

Burmeister says expressly that the legs offer no sexual differences, and other authors

have failed to notice any. The differences, however, so far as regards the tibial spurs

are similar to those of Macrodactylus, though not quite the same. The anterior tibie

have a single spur in both sexes, and the females two on the four hinder legs, but in the

males the hindmost tibie are destitute of spurs in most of the species, and armed with

a single, long spur in others, and the middle tibie have two. Sexual differences exist

also on the fifth and sixth ventral segments.

The head is generally dark, tending to brassy-black, and punctured ; the rest of the

integument castaneous or brown. clothed with ashy or dingy-ashy pile, and presenting

a very variable dark brown design on the elytra. Burmeister describes only one state,

which may be fairly taken as typical, the elytra having twelve large brown rounded

spots, the two central ones of which are ring-shaped, or have a pale centre. The chief

variations from this typical pattern are the following :—

1. The fuscous spots all ocellated; pile longer and coarser.—Puebla, Jalapa. (Tab. IX. fig. 11.)

2. The same reduced to thread-like rings.—Coatepec. .

3. Spots coalescing to form two broad oblique belts.—Jalapa, Toxpam. (Tab. IX. fig. 12.)

4, Pile finer, leaving the striz (partly geminated) visible; the brown spots paler and more rufous

in colour, generally coalescing in two belts.—Capulalpam, Juquila.

5. Var. I. piperitus. Spots much reduced in number and size, or entirely absent ; elytra sprinkled

throughout with minute blackish spots.——Juquila, Oaxaca, Toxpam, Jalapa, Coatepec.

from these species in the colours of the adpressed pile and in the markings of the elytra.

The false subapical suture of the fifth ventral segment in the female is sharply marked,

pile abruptly ceases there, leaving the apex and the large sixth segment glabrous.

BARYBAS.

Barybas, Blanchard, Cat. Coll. Ent. i. p. 94 (1850); Leacordaire, Gen. Col. iii, p. 260 (1856).

Microcrania, Burmeister, Handb. der Ent. iv. 2, p. 26 (1855).

Burmeister (J. c. p. 536) shows that the first of Blanchard’s two species, B. varieyatus,

Germ., is wrongly named, being an Jsonychus, and thinks that his second, B. nanus,

does not belong to the genus, but is synonymous with his Hercitis pygmea. ‘There

is room to doubt the latter identification ; and Blanchard’s phrase, “‘ ungues—posticorum

—externo majore simplici interno fisso,” may be regarded as sufficient to fix the genus,

in spite of the incompleteness of the whole diagnosis. Lacordaire’s definition fills up

the lacunes in Blanchard’s, but is some months posterior in date to the still better

description of Burmeister.

The genus is peculiar to Tropical America, and numerous in species, though barely

half a dozen are yet described. It is interesting as showing a relationship to the

Hopliine.

Among the numerous cases of involved and almost inextricable synonymy created by

the independent publication of Burmeister’s monograph of the Melolonthide, that

resulting from the opposite view taken by him and Blanchard of the genus Philochlenia.

is perhaps the worst. Burmeister had been many years working at his monograph of

this family, and Blanchard’s descriptive catalogue having in the meantime appeared,

he found the task of reconciling his work with that of his predecessor hopeless,

and brought it out with a few synonymical notes only in the Appendix. Lacordaire’s

‘Lamellicornes’ volume appeared too soon after Burmeister’s publication for the

revision which that patient and keen-sighted entomologist would otherwise, no doubt,

have undertaken. Philochlenia, up to Blanchard’s time, was a catalogue-name only,

and although it then included more than one distinct generic type urgently in need of

defining, this author unfortunately chose, as its first or typical section, species which

make it virtually a synonym of the much older genus Plectris. A generic name

which it would have been useful to retain thus falls through, unless the extreme

inequality and separate movability of the tarsal claws of the first section should

hereafter render it desirable to retain Philochlenia as a genus distinct from Plectris.

Burmeister’s genus Philochlenia, on the other hand, consists chiefly of species wrongly

included in Plectris by Blanchard. ‘The majority of these seem to me to form a

natural genus allied to Plectris in facies and in the relative length of the basal

joint of the hind tarsi; but differing in the claws being all equal and more or less

divaricated, and in the elytra having a distinct membranous border, the border being

at most a fine hair-fringe in Plectris. They all have a sinuated clypeus, and the

labrum so deeply sinuated as to be bilobed—characters which all Burmeister’s Philo-

chlenie do not possess, for his P. chalcea (=Alvarinus submetatlicus, Blanch.), and

possibly most of his Section I., have a rounded clypeus and small arcuate-emarginate

labrum. ‘The posterior tibie have two apical spurs in both sexes. ‘This group is con-

generic with the Pseudoserica marmorea of Guérin, and it will be in accordance with

the rules of priority, therefore, to resuscitate Gu¢rin’s name in re-establishing the

genus on a broader basis.

I have seen about a score species belonging to Pseudoserica, very few of which

answer the description of the twenty or thirty described by Blanchard and Burmeister.

They are peculiar to Tropical America.

Subfam. DIPLOTAXIN AL.

This group is distinguished from the “ Macrodactyline ” (with which it agrees in the

free labrum and abdominal segments and in the conical, obliquely exserted, anterior

coxee) by the nearly equal lengths of the ventral segments 2-5. Species in which the

fifth ventral segment isa little the largest are found in Liogenys only, which is thus

shown to be a connecting-link with the ‘‘ Macrodactyline.” ‘The obliteration of the

suture between the fifth ventral and the penultimate dorsal segment, adduced as a dis-

tinguishing character by Leconte, holds good with American genera, although there is

a trace ofa suture in some examples (not in others) of Liogenys palpalis*, In all, the

thorax in front has a membranous margin, and the elytraa very narrow similar margin.

punctulatis vix costulatis; corpore subtus pygidioque annulato-punctatis ; tarsis subtus dense pilosis,

The additional antennal joint, the fifth, is very small. The species differs from the equally 10-jointed

P. flavohirta, Blanch., which is apparently still more widely distributed in Equatorial South America, by its

smaller size (P. flavohirta being 12 to 14 millim.) and the finer and much less dense sculpture; both differ

from P. setisparsa in the numerous long erect hairs (scattered partly in lines on the elytra and forming a

rather dense brush on the thorax), which rise far above the short reddish-tawny subrecumbent pile. In

P. amazonica and P. flavohirta the first joint of the hindmost tarsi is equal in length to joints 2-4, and about

double the length of the second; in the following species it is still longer absolutely and relatively :—

Pseudoserica longitarsis.

Inter P. flawohirtam eb P. amazoncam; ambobus differt thorace densissime (haud confluenter) punctato, elytro-

* The obliteration of the suture is not peculiar to the Diplotaxine ; it is seen in some Macrodactyline, e. g.

LIOGENYS. 155

Liogenys is so closely linked to Diplotasxis by finely graduated forms and the structure

is so nearly identical, that there is no reason for the sharp separation of the two genera

as hitherto made in classifications of the Melolonthide.

So closely resembling the Chilian ZL. palpalis (Eischsch.) that if it were not for the

much narrower dilatation of the male tarsal joints I should have little hesitation in

referring it to that species. The form, colour, pubescence, punctuation, and shape of

the head are exactly as in ordinary examples of ZL. palpalis; but the hind tarsi are

longer, much thinner, and less hairy beneath; and the dilated second to the fourth and

the base of the first joints of the two anterior pairs are much narrower than long, the

fourth of the anterior and the second to the fourth of the intermediate pair further

differing in being only a little broader than undilated joints.

Named Philochlenia clypeata (Deyr., MS.) in the Sallé collection; but the broadly

arcuated labrum and the non-elongated fifth ventral segment show that it does not

belong to the same subfamily even as Philochlena. ‘The short bristly clothing and

(in the male) rather elongate and quadrate clypeus of this and the preceding species,

though opposed to the typical forms of Diplotaais, cannot suffice to distinguish them

generically from that genus.

The totally different clothing of the soles of the male tarsi and the length of the

joints in species so very closely allied in other respects as D. clypeata and D. pilifera

show what abrupt variations have been at work in the group.

Hab. Mexico, Vera Cruz!?, Capulalpam, Cordova, Silao, Cuernavaca (Sallé), San

Usually dark brassy-green or bluish in both sexes, with the antenne (except the club)

reddish ; but varieties occur (at Silao and Guanajuato) in which the elytra and legs

are more or less rufous, and the female in some cases wholly dull reddish-brown. The

brown variety of the female was cited by Burmeister as synonymous with D. simplex

(Blanch. J. ¢. p. 172), but this appears doubtful.

The clypeus is large, as in Section I.; but is trapezoidal and not quadrate in the male,

although the anterior angles are more acute owing to the sinuation of the front edge

and a slighter sinuation of the lateral margin near the angle. ‘The sixth ventral seg-

ment is exposed in both sexes, and the male tarsi (especially the four anterior), though

not at all dilated, are fringed with hairs beneath, as correctly described by Burmeister.

The thorax is always finely and densely punctured; and the elytra a little more coarsely

and subrugosely punctured, but with the punctures distinct.

4, Diplotaxis cribraticollis.

Diplotaxys cribraticollis, Blanch. Cat. Coll. Ent. i. p. 171°.

Hab. Mextco', Tepansacualco, Yolos, Guanajuato (Sad/é).

According to the Sallé collection, this is the largest of a small group of Mexican and

Guatemalan species, of uniform reddish-testaceous (sometimes a little darker) colour,

in which the males have a broad trapezoidal clypeus with prominent angles and sinuated

front edge; the sides of the clypeus a little irregular and the surface concave and

more coarsely punctured than the forehead; the thorax strongly rounded behind the

middle and narrowed thence to the head, with rounded hind angles; and the tarsi in

the male fringed beneath with fine hair.

The Sallé specimens are 10-11 millim. long (Blanchard gives 10 millim.); the

flat interstices between the geminated strize are not * levibus” as Blanchard states, but

have a row of punctures; and the anterior tibize are not “bidentatis,” but show a

distinct though small third upper tooth. If they really belong to Blanchard’s species,

that author’s description of the thorax as “dense subtiliterque punctato”’ is not very

fitting, as the punctures, though finer than those of the elytra, are tolerably widely

scattered over the surface.

(Blancaneaux); Guatemata (Sallé), near the city (Champion) ; Costa Rica, Volcan de

Trazu (Rogers).

In all the numerous examples of the male the sides of the head form a straight,

sometimes slightly incurved, line from the ocular canthus to the apical angle of the

rather narrow trapeziform clypeus. Gradations occur between this simple outline and

a form in which the sides are angularly flexuous; of these the following two varieties

are distinguishable :—

Var. 1. D. consentanea (Chevr. in coll. Sallé)— ¢. Gracilior ; clypei lateribus juxta apicem sinuatis, dentis

apicalibus acutioribus ; fronte medio antice plerumque concava.

dilatatis.

Hab. Mexico, Salazar, Toluca, Durango city (Hége), Mexico city (Plohr, Hoge).

This variety resembles much Liogenys quadridens (Fabr.) ; the clypeus, however, is

much longer and the lateral dentiform dilatation does not form a long sharp

tooth.

A further variety, differing in colour only from the typical D. trapezifera, but

sometimes showing a slight lateral sinuation near the apical angle of the clypeus,

Var. 3. D. bicolor. Supra castaneo-fusca (thorace, scutello elytrorumque limbo interdum rufis), subtus rufo-

testacea. :

Hab. Mexico, Yolos, Peras, Oaxaca (Sa//é).

The species varies also in a rather important structural character, viz. the form of

the lower apical tooth of the claws: in the vast majority of specimens this is, as in

most other species, broader (especially at the apex) and more curved than the upper,

but in others it is gradually tapering, like the upper tooth. Examples of this variation

160 LAMELLICORNIA,

are from Presidio and Tejeria, and offer no other character to distinguish them from the

ordinary form of the species. |

A typical male specimen from Jalapa is figured.

sed discrete punctatis.

Long. 64 millim.

Hab. Mexico, Presidio (forrer).

Evidently more distinct from the typical D. trapezifera than any of the varieties

described above. ‘The clypeus is not quite so long, and is rather angularly sinuated on

its front edge. ‘There is little or no difference in the form of the thorax or in the

sculpture of the upperside; but the underside is thickly strewn with large circular

punctures.

Three examples in the Sallé collection labelled D. nitidicollis, Blanch., agree fairly

well with the description. ‘The clypeus is short and broad, trapezoidal, with the front

edge sinuated and the angles slightly prominent but rounded and each side towards the

gene broadly and angularly sinuated. In the male the pygidium is flat, and the sixth

ventral segment exposed; in the female it is convex, and the sixth segment concealed.

8. Diplotaxis poropyge.

Oblonga, convexa, erecte fulvo-pilosa, castanea interdum cuprascens, subnitida; capite alveolato-punctato ;

clypeo brevi, trapezoidali, angulis latis obtusis sed prominulis, lateribus paullo sinuatis; thorace grosse

limiting the costz, the latter being only faintly indicated.

Apparently allied in some respects to D. rugosipennis, Blanch., which has, however,

the antenne, palpi, legs, and pygidium red. The males have not finely fimbriated

anterior tarsi as in D. wnea. The colour is uniform. We figure an example of the

variety from Pachuca.

11. Diplotaxis coriacea.

Angusta, zeneo- vel cupreo-fusca, dense et sat longe griseo-pilosa ; capite parvo, clypeo trapezoidali supra concavo,

antice valde sinuato, discrete (fronte dense) punctato; thorace longe post medium rotundato-dilatato

(angulis rotundatis) deinde antice valde angustato, dense equaliter punctato; elytris dense subrugulose

punctatis, costulis vix perspicuis; pygidio densissime, ventre paullo sparsius, grosse punctatis; palpis

antennisque rufis; pedibus piceo-rufis; tibiis anticis acute 3-dentatis.

Long. 63-8 millim.

Hab. Mxxico, Presidio and Ventanas (Forrer), Cordova (Saillé).

The pubescence in well-preserved examples is tolerably long, slanting, dense, and

regular over the whole surface from the forehead to the pygidium inclusive; on the

underside it is abundant, but more irregular in length. The single example from

Cordova in the Sallé collection (bearing the MS. name Diplotaxis coriacea, Klug) is

more brassy and has the pubescence shorter (partly abraded) than Forrer’s specimens

from more northern localities.

The head is not very different in shape (comparing examples of the same sex together)

from that of D. wnea; but the clypeus appears to be a little narrower,.and more

narrowed in front, with sharper apical angles.

13. Diplotaxis parvula.

Diplotaxis parvula, Burm. Handb. der Ent. iv. 2, p. 264+,

Hab. Mexico}, Juquila (Sallé).

A glabrous and shining pitchy-black species, with short and broad trapezoidal,

unsinuated, very coarsely punctured clypeus, the forehead depressed in the middle,

and sparingly punctured thorax, pygidium, and abdomen. ‘The sutural interstice of

the elytra is minutely and rather thickly punctured.

14. Diplotaxis sinuaticeps.

D. parvule proxime affinis, differt colore zenescenti-nigro, abdomine crebrius et grossius pygidioque grossissime

segmento 6° exserto.

Long. 64-8 millim.

Hab. Muxico, Jalapa, Vera Cruz (Hoge), Playa Vicente (Sailé).

The sutural interstice of the elytra has only a single row of minute punctures. Many

examples from Jalapa and Vera Cruz, and a single one from the Sallé collection ;

the last named is castaneous in colour, probably from immaturity. I received this

species many years ago from Paris under the MS. name D. sinwaticeps, Reiche. The

name cannot refer to the outline of the clypeus, but to the frontal suture.

15. Diplotaxis juquilensis.

Elongato-oblonga, rufo-castanea, supra cupreo-fusca, nitida, glabra ; clypeo brevi et lato trapezoidali, angulis

In the male the apex of the elytra projects beyond the pygidium. The outline of

the clypeus is very similar to that of the female of D. nitidicollis.

The supposed female differs from the male, apart from the much shorter clypeus, in

the large punctures on the sides and apex of the ventral surface being much fewer in

number, and in the lower tooth of the claws being a little broader and more curved.

This insect bears the name of D. simplea, Blanch., in the Sallé collection, and is

probably that species, though the description is too vague to determine the point

satisfactorily. As some help towards identifying the insect, which is probably common

in collections, I have redescribed it.

Hab. Mexico, Ciudad in Durango (Forrer).

An insect of singular aspect, owing to the anteriorly narrowed thorax. In other

respects the species is normal, except that the labrum is more deeply emarginated ;

the emargination (as in other Diplotaxes) is broadly arcuated and obliquely upwards

and backwards, but instead of leaving as usual a broad upper rim entire, nearly the

whole of the centre of the organ is cut away.

Two examples.

CHL/AENOBIA.

Chlenobia, Blanchard, Cat. Coll. Ent. i. p. 116 (1850) ; Lacordaire, Gen. Col. i. p. 265 (1856).

Lacordaire placed this genus in the “Subtribu Macrodactylides”; but it differs from

that group in all the characters which distinguish the “ Macrodactylides” from the

CHLAENOBIA. 167

“ Rhizotrogides.” It has, namely, long and sessile anterior coxe, much longer than

the breadth of the free lateral space of the prosternum ; and equal ventral segments

2-5, with their sutures in the middle soldered. The general form and minor characters

of the species also are those of Lachnosterna and Phytalus, and not of the “ Macro-

dactyline.” The males are distinguishable from the same sex of Phytalus only by the

tarsi being thickened, and densely hairy beneath. The mandibles are exserted, curving

over the edge of the ligular part of the mentum; the tarsal claws are dentate at the

base and subequally and strongly bifid at the apex; the spurs of the hind tibiz in the

males are both freely articulated.

The only species hitherto described is Brazilian.

This species is labelled Liogenys angustata, Chevr. (MS.), in the Sallé collection ; the

specific name I cannot adopt, as it would be very inappropriate in the genus to which

the insect really belongs. ‘The tarsi are shorter and the joints much broader than in

C. egrota, joints 2-4 being more than half as broad as long. There is no rudiment of

a third (upper) tooth on the anterior tibie in the male, which is perceptible in the

other species, and only a slight indication of it in the female.

Hab. Mexico, Tomatlan, Tuxtla (Sal/é).

Three female examples only. The very different structure of the pygidium, which

has no ventral horny plate simulating a seventh ventral segment, supported as this

character is by the somewhat smaller, more rounded, and more coarsely punctured

thorax, justifies the separation of this insect from C. twmulosa.

The striking modifications in the secondary sexual characters, in closely-allied forms

of this genus, forms which other circumstances indicate to be only local varieties, are

of great physiological significance.

The simple claws of the four anterior tarsi distinguish this genus from both Chle-

nobia and Phytalus; the absence of dense pubescence from the soles of the tarsi (in the

male) further distinguishes it from Ch/@nobia, to which it is most nearly allied by the

form of the head and thorax and the long and stout filiform tarsi. The spurs of the

hind tibiz are both freely articulated, both long and slender, but the lower shorter

than the upper.

Two male examples from Jalapa agree with Blanchard’s description, especially in the

margin of the clypeus being remarkably narrow and slightly reflexed, “ clypeo angus-

tissime reflexo ;” the outline of the clypeus is nearly semicircular. In colour they are

reddish or brownish-castaneous, the elytra dull, the thorax shining. The forehead is

convex and roughly sculptured, not plane as in L. clavatus, L. scuticeps, and allied species,

and the vertex has a very obtuse elevation from eye to eye, probably the “ capite... vix

carinato” of Blanchard; the outer hind angles of the posterior coxe are very much

produced, almost falcate. ‘The sides of the body are fringed with remarkably long

outstanding tawny hairs, and the claws are all uniformly pectinated. Two females from

Las Vigas are darker in colour. The sexual characters are as follows :—

Horn, from Arizona and New Mexico; but differing sufficiently in the sculpture and

clothing of the pygidium, form of the ventral segments, and general colour. The con-

vexity of the lower part of the pygidium in the female may be described, in other

joint of the maxillary palpi slender, and the mandibles concealed. |

PHYTALUS.

Phytalus, Erichson, Naturg. Ins. Deutschl. iii. p. 658 (1848) ; Burmeister, Handb. der Ent. iv. 2,

p. 845 (1855) ; Lacordaire, Gen. Col. i. p. 287 (1856).

A genus distinguished from the following (Lachnosterna) only by the mode of denti-

tion of the tarsal claws, the usual inner tooth, which in Lachnosterna varies in position

from near the base to near the apex, being here apical, so that the claws are properly

termed fissile or cleft. The examination of a large series of species has proved the

correctness of Lacordaire’s opinion that this character would eventually prove untenable,

for I find that every gradation exists between a typical Phytalus with cleft claws, and

the section of Lachnosternain which the tooth is placed near the base. I retain the

genus, however, as a convenient group, in the belief that a division of the great genus

Lachnosterna into numerous genera will soon become indispensable, and that Phytalus

will probably then be retained under some restricted definition.

I have not here restricted the genus to those species in which the inner or lower tooth

of the claw is equal in length and subparallel to the apical portion, but have found it

necessary to include in it a numerous group in which this tooth is more or less short

but nearly parallel, and others (P. pubicollis, Blanch.) in which it is considerably deflexed

and divergent though always nearer the apex than in Lachnosterna. Tiven thus

modified, the fissile character of the claws applies strictly to the males only; the females

in some species (e. g. P. obsoletus) having the lower tooth rather widely divergent, thus

approaching the form presented in Section IV. of Zachnosterna. In facies and in nearly

all points of structure on which genera are founded in the ‘ Rhizotrogine ’ there is no

agreement among the species. For example, the number of antennal joints varies from

10 to 8, the intermediate joints varying in relative length, and the leaflets of the club

vary in number in the males from 3 to 5; the lower spur of the hind tibie, generally

articulated, is in some species connate ; the mandibles are visible or not in repose; and

the clypeus is of the most diverse formation. But it must be added that no better

result follows in this instable series of forms when any other leading character is taken

as a basis for grouping.

A score of species of Phytalus have been described. Like Lachnosterna it is found

in America and in South-eastern Asia; but unlike that genus it appears to be scarcely

represented in temperate North America, where Lachnosterna abounds in species.

The genus is not mentioned by Leconte in his important work on the Melolonthide

of the United States published in 1856; but I have seen specimens of a species,

apparently undescribed, from Arizona.

There are many examples in the Sallé collection of both of Blanchard’s species, appa-

rently correctly named, and after a long study of a numerous series of similar individuals

from various localities I fail to discover any constant character whereby they may be

distinguished. The males of both agree in the highly peculiar form and clothing of

the ventral segments, the description of which by Burmeister may be supplemented, as

follows :—

3. Venter medio longitudinaliter concavus, densissime fulvo-pilosus ; segmento 5° postice sublobato-producto,

6° medio contracto. Pygidium convexum, sparse punctatum ; margine apicali reflexo, fimbriato.

In the female the pygidium is very slightly convex and unituberculated near the apex ;

the tubercle varies in size and a little in its distance from the apical margin, the largest

individuals (labelled P. obsoletus in the Sallé collection) having it furthest removed

from the margin and more erect.

In both sexes the spurs of the hind tibie are freely articulated, long, and pointed.

The tarsal claws differ considerably according to sex. In both male and female the

base of each claw is very little and very gradually dilated, not dentate; in the male the

apex is cleft, with the lower tooth broader than the upper; in the female the claw

cannot be said to be cleft, but is furcate, the lower and broader tooth being removed

nearer to the middle of the claw. In length the species varies from 14 to 21 millim.

P. obsoletus bears a very close resemblance to Lachnosterna testaceipennis.

2. Phytalus punctuliceps.

P. obsoleto similis ; flavo-testaceus, thorace vix rufiore verticeque nigricanti, glaber, nitidus ; differt capite, thorace

Hab. Mexico (Ghiesbreght 1, Sallé ex coll. Sturm).

The single example in the Sallé collection bearing the above name agrees fairly well

PHYTALUS. 177

with Blanchard’s description and is a male. This specimen has the clypeus rather

small and nearly semicircular, without the usual sinuation of the front margin. The

secondary sexual characters are as follows :—

3. Pygidium parum convexum, nitidum, pilosum, irregulariter annulato-punctatum. Venter medio late

canaliculatus, nitidus, sparsim setosus, segmento 6° transversim concavo. Tibiarum posticarum calcaria

elongata, libera.

The tarsal claws are, as Blanchard states, short and curved. The lower tooth is very

broad and curved, and the basal stem of the claw is short and broad without the usual

tooth-like dilatation. I leave the species in the present genus with reserve.

It differs little in the form of the claws from Lachnosterna testacetpennis.

6. Phytalus (?) ——?

Hab. Mexico, Ventanas in Durango (Hége).

A female example of a species certainly allied to P. pubicollis, but with the lower

tooth of the claws much curved and deflexed, and consequently not strictly belonging

to the genus.

medio transversim concavo. Tibiarum posticarum calcaria elongata, gracilia, libera. Ungues omnes basi

Long. 21-24 millim.

Hab. Nicaragua, Chontales (Belt, Janson); Panama, Chiriqui (coll. Bates).

Four examples, all males.

This species is the analogue (in Phytalus) of the L. crenulata group of Lachnosterna

(Leconte’s Group XII.); the totally different form of clypeus and other characters,

besides the generic difference in the claws, forbid the supposition of a real affinity.

A Chontales specimen is figured.

b. Lower tooth of the claws not much shorter than the upper ; lower spur of

the hind tibie connate.

Hab. Muxico, Las Vigas (Hége).

Numerous examples were captured by Herr Hége. P. trichodes is an oblong-ovate

species of tawny or reddish-ochreous colour, and densely clothed throughout with rather

short erect tawny hairs. The tarsal claws are dilated at the base, and, as in P. obsoletus,

differ as regards the apical fissure according to sex; the following are the secondary

sexual characters :—

This species is the analogue of the JZ. élicis and L. hirticula group of Lachnosterna

(Leconte’s Group IX.); but it is only an analogy, or the recurrence of similar external

features, as clearly demonstrated by the numerous important points of structural

difference.

A species remarkable for its long shovel-shaped clypeus, the anterior recurved margin

of which projects far beyond the labrum. The mandibles are not visible and the tarsi

are robust-filiform, characters which show that the insect is closely allied to hizo-

trogus. It bears the unexpressive name Ancylonycha pallida, Sturm (MS.), in the

Sallé collection.

There is a single male example only of this remarkable insect, which, notwithstanding

the eccentric structure of its antenne, seems to be perfectly congeneric with the other

PHYTALUS. 183

Two examples of the type, both males. The antenne are elongated both in stem

Long. 10-11 millim.

Hab. Muxico, Ciudad in Durango (Hége). Two male examples.

Very closely allied to P. wgrotus, but sufficiently distinct by the clypeus being much

shorter, broader, and less quadrate, and sinuated on its front margin. ‘The lower tooth

of the tarsal claws is also rather longer and narrower. The thorax is clear testaceous-

red and not castaneous on the disc as in P. wgrotus and its var., which latter partly

bridges over the difference between the two species.

25. Phytalus fissilabris.

Hab. Muxico, Orizaba (Sailé), Las Vigas (69e).

Two examples only. ‘The male, which is imperfect, has more voluminous eyes, and

a more deeply sinuated and more reflexed clypeus, than the female, and the forehead

and thorax clothed, but not thickly, with long, fine, erect hairs. The short clypeus

with its large median sinuation causes the labrum to be prominent and exposed.

3. Antenne 8-jointed, the fifth joint very short.

26. Phytalus poculifer.

Parvus, breviter ovatus, livido-fuscus, nitidus; antennis pedibusque fulvo-testaceis, glaber, fronte thoraceque

A single male example, somewhat immature. The concealed mandibles and 8-jointed

antenne would bring the species within the definition of Erichson’s genus Anonetus ;

PHYTALUS.—LACHNOSTERNA. 185

but the dentition of the claws is widely different, Anonetus being defined as having a

quadrangular tooth at the base of the claw. It will be seen further on that a section

of Lachnosterna has also 8-jointed antenne, and, in some examples but not in others,

concealed mandibles, so that the genus is evidently untenable.

The species with more or less narrowly-cleft tarsal claws being excluded to form the

unsatisfactory genus Phytalus, a polymorphic host of nearly 200 described species

remain, which it is extremely difficult to arrange in natural groups. After trying

various courses, | have preferred to take the armature of the claws as a basis of

grouping, finding that the result does less violence to the apparent natural affinities of

the species than is shown when any other varying character, such as the structure of the

-antenne, the parts of the mouth, or the secondary sexual characters, is adopted. I do

not wish it to be inferred that the groups are perfectly natural and applicable to the

species of other regions; in fact they apply very imperfectly to the Lachnosterne ot

temperate North America, and not at all to Asiatic species. But neither does the

system adopted in Leconte’s synopsis of the North-American species suit the forms of

the Tropical-American fauna.

The genus is very numerously capieenill in our region, particularly in Mexico, and

judging from the many single specimens of apparently distinct species met with by our

travellers, and that continue to arrive, it is highly probable that we are not acquainted

with one half the species that exist in the country. ‘The genus seems to diminish in

the number of its representatives further south, but many are described from Colombia,

Venezuela, and the West Indies; in the plains of the Amazons it is practically unknown,

Hab. Mexico, Capulalpam, Peras (Sal/é).

Two examples, both females. This is the only species known to me in which the

claws of all the feet have equidistant and similarly-formed acute teeth, differing only in

their gradually increased length; the basal tooth is a prolongation of the apical angle

of the long and broad basal dilatation.

The species is evidently closely allied to L. heteronycha.

Hab. British Honpuras, R. Sarstoon (Blancaneaur); GuaTEMaLA, Cerro Zunil

(Champion).

Two examples, both females. Closely allied to Z. piceola, but differing too much in

the outline of the clypeus and in the punctuation of the thorax to admit of the suppo-

sition that it is the female of that species. ‘The Guatemalan example is figured.

Long. 18-16 millim.

Hab. Mexico, Toluca, Peras (Sal/é).

Two males from Toluca; two females from Peras: the difference in the outline of

the clypeus may, therefore, indicate a local variety. In all other points the specimens

agree perfectly. They are named L. foveicollis, Sturm, in the Sallé collection, but are

certainly a different species from the one described under that name by Sturm.

A male specimen from Toluca is figured.

Hab. Mexico, Parada, Oaxaca (Sallé).

Three examples. The great difference in the punctuation and pubescence of the

pygidium, in both sexes, indicates a species distinct from L. leonina, though the form

and sculpture of the head, thorax, and elytra are almost exactly similar. The sixth

ventral segment in the male shows no trace of the depressed median area, or wide

shallow fovea, which is so definite a character in the two males examined of L. leonina.

The fine and close punctuation of the pygidium extends very near to the apex, and the

pubescence is long and flatly adpressed like that of the propygidium ‘and the sides of the

abdomen, but the pubescence is easily abraded. In L. leonina the base of the pygidium

is clothed with very long, erect hairs, and the apical third is glabrous.

8. Lachnosterna dulcis.

Hab. Muxtico, Toluca (Hége). Three males.

The three teeth of the claws are, as in L. cribricollis, separated only by narrow clefts,

the apical one being much the longest, the basal quadrate. In colour and in the very

long, erect hairs of the anterior part of the body ZL. dulcis resembles L. leonina; but it

is a broader and much smoother insect, and the elytra are destitute of the short hairs

distinguishing L. leonina.

exception that those of the intermediate pair are not distorted, are nearly as in L. ravida

and JL. testaceipennis, that is, they have a broad basal tooth, a less broad and longer

median tooth, and a long sharp and curved apical tooth, the intervals between all of

which are nearly of the same width. In the female, as usual in the group, the median

tooth is less broad and more gradually pointed than in the male, and the distances

between the three teeth are considerably wider. The other sexual differences are :—

collection labelled Lachnosterna testacea, Sturm (MS.).

The Ancylonycha cribricollis, Redt., in Hiigel’s ‘ Kaschmir’ (1844) is anterior in date

to Blanchard’s name (1850), but is wrongly placed in the genus, being a Schizonycha.

(Blancaneaux) ; GUATEMALA (Sal/é).

The unmeaning phrases which Blanchard thought sufficient to distinguish this

species from the similarly-coloured L. testaceipennis apply equally well to the females

of both species. According to the examples named ZL. ravida (to all appearance

192 LAMELLICORNIA.

correctly) in the Sallé collection, the species offers well-marked distinctive characters in

both sexes.

3. Pygidium mediocriter convexum, disperse punctatum. Venter medio depressus segmentisque 2°-5™ densis-

punctatum, nudum. Venter breviter sat sparse setosus, politus. Ungues basi dente magno sed dente

normali inferiore magis distante, longiore et acutiore.

The claws are remarkable for the large and more or less quadrangular dilatation of

their base, in both sexes. In the male they are further distinguished by the ordinary

tooth lying nearer the base and being separated from the dilatation only by a narrow

cleft, the tooth also being shorter and straighter than usual. In the female the

ordinary tooth lies nearer to the middle of the claw, and is separated from the dila-

tation by a wide interval. The distorted curvature of the left claw in the middle tarsi

is a further curious structure.

L. ravida resembles almost exactly Phytalus obsoletus in colour and in sexual

characters, with the exception of those of the tarsi and claws.

We figure a male example from Oaxaca.

16. Lachnosterna dentex.

exteriore abrupte curvato et extus dente elongato.

Long. 16 millim.

Hab. Mexico, Milpas in Durango (Forrer), Guanajuato (Sal/é).

Two examples, both males.

The claws are toothed similarly to those of L. ravida, but the apex of the claw is not

so elongated and distant from the lower tooth, so that the dilated basal and the lower

and the upper teeth are nearly equidistant. The bent exterior claw of the middle tarsi

has on the outer side a longish projection, which is no other than the median tooth

diverted laterally out of its true position ; this tooth is here of moderate length, but

longer and sharper than in L. ravida.

A single example of a Lachnosterna found by Herr Hoge at Ciudad in Durango is

possibly the female of this species.

Agrees closely in most of its characters with L. anomaloides, and, in the clothing of

the ventral surface, especially with the variety of that species; but the general form is

totally different, being much shorter and relatively broader—this, together with the

long hairs of the anterior part of the body, being constant in numerous examples, there

can be little doubt that the species is distinct.

Belongs to the L. ravida group, of which it is the largest known member. JL. dasy-

poda approaches nearest to L. macrophylla in pubescence; but in the rather ample

subsemicircular clypeus it differs from all its allies.

In the male the median tooth of the claws at its base forms part of the wide dila-

tation of the basal half of the claw, and is small, triangular, and acute; the basal tooth

is not angular but gradually rounded, so that it appears separated by a considerable

interval from the median tooth; the apex remains for a long distance free. In the

female the median tooth has the same position as in the male, but is much longer and

not greatly different in form from the apical tooth, from which it is separated by a much

shorter interval. In the other species of the group the form and position of the claw-

teeth are different, the basal tooth, especially in the male, being angular and separated

from the median tooth by a narrow cleft.

A male from Tuxtla is figured.

Hab. Mzxico (coll. Bates). One male example only.

The first joint of the 5-jointed antennal club is one third shorter than joints 8-10,

and the second is only one sixth the length of those joints. The similarity between this

species and the preceding is so great that I should have been inclined to consider the

change in the proportionate lengths of the leaflets of the antennal club as due to

variation or aberration, had it not been for the different form and clothing of the

pygidium and the shape of the clypeus.

Ill. Claws broadly cleft ; base moderately dilated ; lower tooth very broad and strongly

curved, and denticulated on tts lower edge.

Many examples in the Sallé collection under the above name agree with Blanchard’s

description of this insect. It can be best distinguished from the other numerous pale

or reddish-testaceous species of medium size (15-18 millim.) by the structural peculi-

arities of the sexes, which are as follows :-—

6. Pygidium convexum, nudum, grosse sed haud profunde rugoso-punctatum. Venter medio anguste

depressus, nudus, politus, segmento 4° apice medio et 5° toto medio dense aspere rugulosis, 6° late

transversim depresso, grossius rugoso-punctato, interdum medio canaliculato. Calcaria postica libera,

sed minus elongata laminato-compressa. Ungues dente inferiore multo breviore et latiore, apice truncato

subhamato margineque inferiore plus minusye denticulato; basi usque ad dentem equaliter dilatata.

Antennarum clava elongata.

(convexo) setifero-punctatis. Calcaria postica brevia et late compressa. Ungues dente inferiore sub-

mediano lato sed acuminato, margine inferiore denticulato.

In most examples of the very numerous series examined the surface is dull, and, the

thorax especially, pruinose; but in others from the same localities the surface is glossy

without trace of pruinosity.

LACHNOSTERNA. 197

Three examples, besides one in my own collection received from Paris under the

name J rorida, Burm., from which it is evidently distinct, and which is, moreover,

a South-Brazilian insect. I have seen only one male (from Teapa) ; it differs slightly

from the three females, and is much smaller (20 millim., the females being 25 millim. ),

and seems intermediate between this species and L. rorulenta, but the punctures have

each a small grey seta.

26. Lachnosterna cinnamomea, (Tab. XI. fig. 8.)

Ancylonycha cinnamomea, Blanch. Cat. Coll. Ent. i. p. 134°.

Hab. Mexico 1, Cordova (Saldé).

Extremely near L. parvisetis, but glabrous, without pruinose bloom, and the punctures

naked. Colour castaneous, shining. In the male the pygidium is polished and flattened

towards the apex ; the lower hind spur is rather longer than in L. rorulenta, but soldered

to the tibia; the ventral segments are sculptured precisely as in that species. In the

female the pygidium differs in the apical area being more depressed and margined

laterally by much higher ridges.

2. Lower spur of the hind tibie freely articulated.

27. Lachnosterna sturmi. (Tab. XI. fig. 9, ¢.)

Phytalo pruinoso similis. Anguste oblonga, subcylindrica, fuligineo-nigra, elytris plerumque rufescentibus,

Hab. Mexico, Cordova, Orizaba, Tuxtla, Playa Vicente (Salle).

Closely resembling in form and sculpture Phytalus pruinosus, but widely differing in

the spurs of the hind tibise of the male, the form of the tarsal claws, and other important

points of structure. It appears to have been hitherto confounded with P. pruinosus

(Burm.); it being so named in the Sallé collection (by Sturm) and in my own from

specimens received years ago from Paris. I have examined nine examples.

The clypeus is a little more deeply notched in the middle of the front margin than

in P. pruinosus, and the sides are less convergent.

Our figure is taken from a female specimen from Tuxtla.

Seven examples, of which three from Chiriqui are black or brownish-black, including

the legs and antenne; the others are castaneous (including the antenne and legs) ;

one (from Chontales) differs from the rest in having but a slight trace of sinuation in the

anterior margin of the clypeus. In all other respects the specimens perfectly agree.

A Chontales example is figured.

Hoyopuras, R. Sarstoon (Blancaneaux); Guatumata (Sallé), Volean de Atitlan, Pan-

taleon, Zapote, Duefias (Champion); Panama, Chiriqui (£7d0e).

Distinguished from L. crinalis by the sixth ventral segment in the male having its

anterior margin raised and dilated above, so as to impend slightly over the concave

centre of the segment, and cleft in the middle. ‘This structure is no doubt that meant

by Burmeister by the phrase “die analgrube mit hoher, in der mitte gespaltener

Querfalte am Vorderrande.” A similar “fold” is observed in L. longipilosa 3, but

there is a difference between the two species, the fold being biarcuated in L. setifera,

and produced in the middle, the margin of the preceding (fifth) segment being corre-

spondingly produced; in L. longipilosa the margins of both segments are straight. In

L. crinalis the fore margin of the sixth segment is somewhat thickened but not raised.

L. setifera is further distinguished by the opaque and very faintly punctured

pygidium, which is rather densely clothed with erect greyish hairs, the tip in some

examples being smooth and shining. ‘The claws have their well-developed lower tooth

(a little longer and broader in the female than in the male) very nearly in the middle,

its lower edge being finely denticulated; they have only a slight angular dilatation at

the base, and there is a considerable interval between the dilatation and the tooth.

LACHNOSTERNA. 199

The clothing of the upper surface consists of obliquely-planted grey hairs with a few

longer erect hairs, and in some examples extremely long hairs, especially towards the

base of the elytra.

The length varies from 17 to 25 millim., but the great majority of the examples

measured are about 20 millim. The following are varieties :—

Purula (Champion); Panama, Chiriqui (Trdtsch), Volcan de Chiriqui (Champion).

A pruinose nearly glabrous species resembling L. rorulenta, but distinguished readily

by the tarsal claws being greatly dilated from the base to the lower tooth, which is

straight and at its base forms part of the dilatation. The male further differs from the

same sex of LZ. rorulenta and its allies by the long and freely articulated spurs of the

hind tibie ; and by the abdomen being concave in the middle, with a deeply canali-

culated sixth segment, and a closely granulated patch on the hind part’ of the fifth

segment. The pygidium is closely punctured and hairy in both sexes. In some

specimens of the female, especially those from Chiriqui, the elytra near the suture are

beset with very long erect tawny hairs. Most Mexican examples of the female show

no trace of these long hairs, but sometimes a few shorter similar hairs are seen near

the base and apex of the elytra. A male from Jalapa is figured.

In the minute dense punctuation and fine short laid pubescence this Lachnosterna

is similar to L. gigantea, black examples being scarcely distinguishable from small

individuals of that species of the same colour. But the male sexual characters are

totally different and the claws show a much closer approximation to the basal dilatation

of the middle tooth, which in the male is short, inclined towards the base, and

separated from the large broad basal tooth only by a narrow cleft.

A metallic species, varying from brassy-black or brown to dark brassy-green and rich

coppery-brown. It is almost glabrous above, having only a scanty clothing of short

subrecumbent grey hairs, mostly arranged in rows on the elytra. The sculpture is

coarse; the punctures moderately close, and lying in very irregular ruge on the thorax,

the elytra entirely rugose-punctate; the scutellum is punctured, with a broad smooth

space in the middle. The labrum is thick and deeply and sharply cleft as in ZL. scissa.

The clypeus is transverse quadrate, with a deep notch in the middle of the front margin,

and each side from the notch to the base forming a nearly semicircular curve. Both

the fore and hind angles of the thorax are acute. The ventral segments 1-4 have

on each lateral suture a pencil of long golden-yellow hairs. The following are the

sexual differences :—

Very similar in form and colours and in important structural characters to

L. euryaspis; the curious wheals on the ventral segment indicate an affinity also with

L. submetallica. The totally different form of clypeus in these three species seems to

show that this is a very variable feature. It resembles in form, colour, and other

characters the North-American ZL. fusca and its allies; but differs from all the species

of the L. fusca group by the lower spur ( ¢ ) being articulated, not connate. The male

variety (which is apparently much less common than what I take to be the typical form)

is so different that we seem here to have a case of dimorphism in this sex; but when a

large series is examined intermediate states are seen to exist. In one male example

the apical ventral segment is nearly as gibbous as in the female, and it is only the

transverse depression at its apex and the longer antennal club which enable one to

decide that it is a male.

49. Lachnosterna segregans.

L. molopie affinissima, differt solum statura minore, clypeo transverso utrinque late rotundato, margine antico

Long. 14-17 millim.

Hab. Mexico, Ciudad in Durango (Hodge). Three examples, all males.

Resembles the smaller examples of L. molopia, chestnut-coloured and glabrous above,

fulvo-testaceous beneath; the elytra more strongly punctate-rugulose. The form of

the clypeus is different, being short, rounded on each side, and rather strongly sinuate

anteriorly, instead of being rather long and obtusely trapezoidal as in Z. molopia. The

callosities on the middle ventral segments are feeble or obsolete; the sixth segment

(male) is formed precisely as in the male variety of L. molopia. The pygidium is coarsely

rugose-punctate as in L. molopia; but the thorax differs in wanting the two large

‘postero-discoidal foveee. The lower tooth of the tarsal claws is very small, outstanding,

and situated about the middle of the claw. The antennal club is greatly elongated,

and longer than the rest of the joints taken together.

50. Lachnosterna divertens.

L. molopie quam proxime affinis; differt solum statura angustiore (anguste oblonga sive cylindrica), clypeo

adhuc magis elongato, semiovato, perparum vel nullomodo sinuato et antennis longissime clavatis.

Long. 17 millim.

Hab. Mexico, Ciudad and Refugio in Durango (Hoge).

Three examples, males. The chief character which necessitates the separation of

this form from L. molopia is (as in L. segregans) the great length of the antennal club

in the male. It differs from both these species in its narrow, cylindrical form, and

in the shape of the clypeus—narrowed anteriorly as in L. molopia, but having

no trace of angles, and gradually rounded to the front and feebly or not at all

notched on its anterior edge, which is scarcely reflexed ; both clypeus and forehead are

more minutely and densely punctured than in L. molopia. The ventral callosities are

feeble or entirely obsolete. The pygidium offers no difference, and the sixth ventral

segment is formed as in the male variety of L. molopia. The tooth of the claw is short

as in L. molopia, but situated a little higher (¢. ¢. towards the apex) than the middle

of the claw ; it varies a little in position, as it does in L. molopia.

The antennal club varies in length, but in the examples in which it is shortest it

equals in length all the remaining joints together. Judging from this and other

evidences of variability or plasticity in this interesting group, I think that we have

here a case of an incipient species in process of segregation.

section to which LZ. farcta belongs (Group II. of Leconte) in the metasternum being

somewhat abbreviated, but differs in being winged in both sexes. It is a Lachnosterna

allied to L. molopia, with which it has in common the two forms of male. The ligular

part of the mentum has a deep notch, and the mandibles and maxille are very robust.

In all the numerous examples the colour of the body, antennee, palpi, and legs is deep

black.

Hab. Mexico ! 2, near the city (Lohr), Jalapa (Hége).

Distinguished from numerous allied species, having a similar entire semicircular

clypeus &c., by its clearer reddish-tawny colour, with very rarely a trace of pruinosity

and that on the elytra only; by the extremely short antennal joints 3-7, with greatly

elongated club in the male (the club being longer than all the rest of the antenne) ;

and by the concave sixth ventral segment in the male having a narrow anterior rim.

The forehead, thorax, and base of the elytra are clothed with very long hairs, and the

elytra have, besides, a short incumbent grey bristle in each puncture. The fifth ventral

segment in the male has a median, densely granulated, and brown oval patch. The

general form is rather short oblong-ovate. This species varies in size from 14 to

17 millim. |

The colour is reddish-tawny, as in L. integra, with only a slight trace of pruinosity,

in some examples, on the elytra. The semicircular concave clypeus and pubescence

also offer no difference; but the general form is rather more oblong and narrower.

The antenne of the males have a similarly long pale club, but the joints 3-7 are

scarcely so short as in L. integra. Two female examples, labelled L. stipitalis,

Hab. Mxxtco, Toluca, Amecameca in Morelos, Pachuca in Hidalgo (Hége).

Among the very numerous examples examined of this insect there are a few males in

which the sixth ventral segment scarcely differs from that of L. integra; in all,

however, of both sexes, the shape of the clypeus is different, and this (in addition to the

smaller size and much closer rugulose punctuation of the elytra, on which there is no

trace of pruinosity) renders it necessary to distinguish the form by a separate name and

description. The four examples of L. anodentata are larger and more elongate-oblong

in form. .

cannot, however, be certain of this, and the identification of this interesting little species

must remain in doubt. I will add to Blanchard’s description that the tarsal claws are

slender, slightly and gradually broadened to the base, without basal dilatation, and

furnished with a short, sharpened tooth near or a little below the middle. This

character seems to forbid the association of L. mexicana with Erichson’s genus Anonetus

(a genus without described species), in which the claws, as I have already stated under ~

Phytalus poculifer, have a quadrate tooth or dilatation at the base.. The mandibles

are invisible in repose in some examples, but quite visible along their external edge,

and at the tips, in others. The species has a structural peculiarity in the width of the

hind coxe, especially at their junction, where they cover the usually visible first ventral

segment, and in some examples also the second.

All the examples appear to be of one sex, apparently male, the sixth ventral segment

being plane or slightly concave, and with the fifth punctulate and clothed with

stiff hairs.

The following species are represented by single specimens only, in some cases

imperfect, and cannot with any advantage be named or located in the above classifi-

EUGASTRA.

Eugastra, Leconte, Journ. Acad. Nat. Se. Phil. ser. 2, iii. p. 233 (1856).

Leconte founded this genus chiefly on the deep emargination of the ligula, a

character which Dr. Horn has since proved, by the dissection of many species of

Lachnosterna, to have no generic value. But Leconte added the characters :—both

sexes apterous, the body above and beneath glabrous. These features, combined with

the extremely short metasternum and the subterranean or epigeous habits of the species,

seem to mark out a definite modification of the Lachnosterna type worthy of generic

distinction.

The genus Tostegoptera, Blanchard, founded on JL. lanceolata, Say, is allied to

Eugastra, but differs in the female only being apterous and having a short metasternum

destitute of villosity, the male being in these respects a typical Lachnosterna. It forms

a transition to the Lachnosterne through L. nigerrima (Bates), in which the male has

a villose metasternum of the normal length, and the female a shortened and scantily

pilose metasternum, but in which both sexes are winged. Tostegoptera is not admitted

as distinct from Lachnosterna by Leconte; in which view he appears to me to have more

justification than he has in including L. wgualis and L. farcta in the latter genus—they

are both much more nearly related to Hugastra; L. farcta (the only one I have been

able to examine) at least having a very short and glabrous metasternum, though winged

in both sexes.

Leconte admits two Texan species only as belonging to the genus, which cannot

satisfactorily be distinguished from the Old-Woyrld Geotrogus.

216 LAMELLICORNIA,

Fam. RUTELIDA.

Subfam. ANOMALINA.

The chief distinguishing character of this subfamily lies in the deflected labrum, the

anterior middle part of which curves downwards so that the front edge is turned under-

neath towards the roof of the mouth. Hence, without dissection, the basal part of the

organ, more or less sinuated in front, is alone visible. It is incorrect to term this

peculiar conformation “labrum emarginatum” as Erichson and after him all the chief

writers on the Lamellicornia have done, the middle of the true front edge of the labrum

being obtusely rounded and sometimes even produced, not emarginated. ‘This difference

is important inasmuch as it lessens the divergence between the subfamilies Anomaline

and the Geniatine, with their allies the Anoplognathine and the neighbouring groups,

two great series of forms which have hitherto been widely separated in the current

classifications.

PHYLLOPERTHA.

Phyllopertha, Stephens, Il. Brit. Ent., Mandib. i. p. 223 (1880) ; Erichson, Naturgesch. d. Ins.

Deutschl. iii. i. p. 627; Lacordaire, Gen. Col. i. p. 327; Burmeister, Handb. der Ent. iv. 2,

Anisoplia (Latreille, Castelnau), Fairmaire, Ann. Soc. Ent. Fr. 1870, p. 378.

Although this genus is generally adopted it has never been satisfactorily defined as

distinct from Anomala, and many species have, in consequence, been referred to it which

have little in common with the typical P. horticola. ‘The two Mexican species included

in Phyllopertha by Blanchard appear to me decidedly not to belong to it, one being an

Anomala, and the other an Hpectinaspis. ‘The following species is a Phyllopertha in

its general form and the slenderness of its hind legs in all their parts, and in the loose

villosity of the under surface of the body; but it differs greatly from Phyllopertha in

the mouth-structure, the mandibles being reduced to very narrow flat tapering blades,

lying closely to the roof of the mouth, and the maxille having two teeth only. Abrupt

degradations of mouth-structure occur, as I shall have to show, also in a group of

Anomale widely different from Phyllopertha, and they cannot well be treated as generic.

A dozen examples showing very little variation. The clypeus. and anterior claws in

both sexes are formed precisely the same as in A. undulata, and I treat A. discoidalis

as a distinct species simply on account of its constancy in the Panama region, whence

nearly all the specimens come. ‘The few Mexican individuals are rather less typical,

the thorax in these having a more or less stronger punctuation, an entire basal margin,

and less sharply defined spot, characters which connect them so far with A. undulata.

The entire second elytral stria distinguishes, besides other characters, this species

from others of the A. undulata group. Yet, widely distinct though it be, it is linked

with A. wndulata step by step by the species or subspecies above described, and the

individual varieties, apparently very rare, intermediate between them. ‘The markings

of the elytra in the thirty specimens examined offer little variation; in what may

be considered typical examples there are, besides the narrow median fascia and the

large rhomboidal subapical sutural spot, an oblong dark spot in the middle of the

base and another similar one towards the apex in the fulvous area between the

rhomboidal spot and the broad lateral border. These accessory spots are often absent,

or the dark fascize more or less diffused.

Burmeister mentioned the differences of sculpture which distinguish A. hépfneri (as a

variety) from the more southerly forms of A. énconstans, but did not notice the pecu-

liarity of dentition of the anterior tarsal claws in the male, which I find quite constant.

The markings of A. hépfneri are also different from those of A. inconstans. 'The sutural

vitta of the elytra is nearly always dilated in the middle, and the apical margin has a

broad velvety-black border seldom entirely absent. The broad trapezoidal spot of the

thorax reaches the base, but there is generally a pale transverse streak in the middle of

the basal part. An example from Peras is figured.

In the male the larger claw of the anterior tarsi is long, subtriangularly dilated near

the base only, and the upper tooth is nearly as long as the lower; in the female the

upper tooth is longer than the lower. ‘The larger size (16-17 millim.), more distinctly

tricostate elytra, with thickly punctured intervals, flatter pygidium, much more obtuse

thoracic hind angles, and different elytral markings (broad and dark discoidal streaks

being the prevailing pattern) further distinguish the species from A. hépfneri. The

subtridentate anterior tibie in the female is a more constant character in this species

than in A. hépfneri.

The examples from Chiriqui (two in number) differ from all the Mexican and Guate-

malan individuals by the elytra being yellow with the suture (narrowly) and the humeral

callus only black, and by the narrower and less punctured intervals between the costz.

Burmeister, in his appendix, stated his belief that his species was probably the

A. lurida of Fabricius—a suggestion of change of name promptly adopted, as usual in

such cases, by subsequent writers. The description of Fabricius, however, as given in

the Syst. Entom., does not in the least apply to A. inconstans in any of its varieties.

The “caput nigrum ” and “ elytra punctis duobus ad suturam et unico versus apicem ”

must refer to some species of a different group of Anomale. The country of Fabricius’

species was unknown. We figure a Guatemalan specimen of A. ¢nconstans.

Distinguished from the three preceding species by the very finely and less densely

strigose and glabrous pygidium. The colour and sculpture of the elytra are similar,

but have a wider range of variation; some Guatemalan examples have the elytra

clear testaceous with castaneous suture; in others the black spots coalesce and the

elytra become blackish-castaneous with a few tawny patches. In most examples the

ANOMALA. 231

geminated lines of punctures are larger than the others and dusky, but they do not

form such distinct linear foveoles as in A. foraminosa.

Several examples in the Sallé collection are labelled A. sticticoptera, Blanch., others

A single very imperfect example of a species deceptively similar to the above, but

with a perfectly even thoracic surface, and remarkable for the extreme narrowness of

the mesosternum combined with a somewhat prominent triangular apex (not tuber-

Two examples of the same sex, and, judging by the breadth of the larger claw of the

anterior tarsi, probably males; the joint is, however, not abruptly dilated. The upper

lower.

slender; the claw is cleft, and the upper tooth is long and moderately robust, though

shorter than the lower. The corresponding claw of the middle tarsi is widely cleft.

In the colour and markings of the elytra the species somewhat resembles Plagiodera

Say described, with his usual aptitude, what must be considered the typical form of

this species, in which the elytra are pale tawny-testaceous with the suture (narrowly)

and the outer margin (especially near the shoulders) blackish-brown. The dark brown

colour in many examples is broadly suffused, and in extreme cases spreads over the

whole surface of the elytra; it tends always to form vague vittee, never fasciz, hence I

very much doubt if the variety described by Blanchard belongs to the same species as

his A. latreillei, to which he refers it.

In some of the localities there occurs what seems to be a variety or varieties in which

the elytra are deep black or bluish-black, metallic bluish-green or coppery, without

trace of pale brown hues. This comes extremely near to A. viridicollis, Burm., from

Colombia, if it be indeed specifically separable from it. All the examples have a small

third tooth on the outer edge of the anterior tibie, in both sexes, a broad very sloping

mesosternum thickened and broadly subtubercular at its apex, unicolorous metallic

(very seldom rufous-translucent) thorax and under surface, and the hind margin of the

thorax interrupted (?. ¢. the marginal stria) in the middle. In A. cincta, type, the

elytra have punctured striz, sometimes faintly, sometimes rather deeply, impressed

with a broad second interstice having a moderate (but very variable) number of con-

fused punctures, and little or no tendency to the formation of geminated strize. The

pygidium is glabrous and shining, and not densely sculptured, with short transverse

striee intermixed with punctures. The variety is as follows :—

Var. A. polychalca., Ceeruleo- vel viridi-eenea (capite thoraceque interdum cupreis), polita, elytris variant nigris

leviter metallicis, chalybeis, nigro-eeneis et cupreis, capite interdum fulvo-rufo.

Some examples of the variety diverge much from the type in colour and sculpture, and

have the appearance of distinct species. Those with brassy-black elytra bear the name

of var. nigripennis, Deyrolle (MS.), in the Sallé collection.

scarcely any difference in colours or markings from Mexico to Panama. The fore

tibie are bidentate; the mesosternum is prominent and slightly porrect between the

In this species the punctures of the sutural stria (which is only impressed towards

the apex) collect in oblong blue-black fovee, similar to the geminated lines of fovee on

the disc of the elytra. In many examples there is a dusky spot exactly in the middle

of each elytron.

Tam not sure of the identification of this species, as none of our examples are so

small as 6 lines (about 14 millim.), the size given by Burmeister. Our Guatemala

specimens measure from 19 to 24 millim. Im all other respects they agree with

Burmeister’s description. In the Sallé collection A. pupillata is identified with a

spotted var. of A. sticticoptera, Blanch. In colour and markings the resemblance is

complete, but the form of the mesosternum, ‘ein wenig vorgezogen,” is quite different

from that of A. sticticoptera. I doubt, however, whether A. pupillata is specifically

different from A. valida.

Closely allied to the North-American 4. marginata (Fabr.), but differs in the

sculpture of the elytra. This, although variable, in A. granulipyga always shows six

interstices between the broad second interstice and the humeral callus, separated into

two groups of three each by a confused line of punctures. Sometimes this division is

not clearly perceptible, except behind towards the apical callus, and the broad second

interstice also varies in its definition. A typical example from El Reposo is figured.

Hab. Mexico}, Cordova, Toxpam, Yolotepec, Chiapas (Sallé), Jalapa, Chilpancingo,

The lateral margin of the elytra is dilated before the middle and wavy thence to the

base like the other species of the section ; but the dilated part is not so much thickened,

even in the female. The mesosternal process is rather short, thick, and obtusely conical.

The base of the thorax is immarginate, and the outer claw of the anterior tarsi broad

and not gradually tapering to the apex.

In colour it varies from the green crown and thorax and green-tinged castaneous

elytra, as described by Burmeister, to coppery or golden head and thorax and rich gold-

tinged red or even violet-coloured elytra; and the pygidium, generally brassy-green, is

sometimes clear yellow. The coppery examples are from Yolotepec and Oaxaca. The

middle of the base of the thorax is often yellow as well as the sides; very rarely the

thorax is entirely brassy-green.

Phyllopertha villosella, Blanch. Cat. Coll. Ent. i. p. 179°.

Hab. Mextcot, Izucar (Sallé), Matamoros Izucar in Puebla, Iguala in Guerrero

(Hoge).

Evidently closely allied to A. micans and A. xantholea, notwithstanding the hairy

clothing of the whole body, which is very dense and erect on the crown and thorax,

and long, ashy-coloured and recumbent on the pygidium, denser still on the propygidium.

The elytra have fourteen similarly punctured striz with narrow interstices, but they are

in some examples somewhat confused by transverse rugee; the median dilatation, espe-

cially in the female, is well marked and explanated, but not much thickened. The

chief difference from A. micans and others of the group lies in the thorax having a fine

basal margin; this, however, is sometimes widely interrupted in the middle, and it does

not then differ essentially from A. wantholea, in which the margin is often very distinct

along the sinus on each side. The greater claw of the anterior tarsi of the male is

especially wide nearly to the apex, where it has almost the appearance of being

obliquely truncated, the upper tooth being very slender and somewhat shorter.

The general form is compact and ovate, and the legs and tarsi are robust; the species

cannot therefore be referred to Phyllopertha.

Blanchard says “ thorace toto viridi;” but not one amongst the many examples I have

examined is without at least a narrow, if somewhat ill-defined, yellowish lateral vitta.

The base of the thorax is emarginate, except in some individuals, on the sides near the

angle; the elytra have only thirteen punctured strie, one of which (the eighth) is much

abbreviated, and the lateral margin is dilated and thickened before the middle. The

pygidium is convex, sometimes gibbous, posteriorly glossy metallic with a few long

hairs. The mesosternum is prominent, briefly conical and laterally compressed. The

colour above is apple-green with a metallic lustre, but sometimes (often the elytra

only) testaceous with pale green lustre, and the thorax with two broad dark brassy-

ereen vitte. The locality given by Blanchard? is “Amer. Merid.”

Anomala rhizotrogoides, Blanch. Cat. Coll. Ent. i. p. 186°.

Hab. Mexico 1, Vera Cruz (Sallé, Hoge).

This species differs from the typical Anomale in many points of structure; the ligula

is narrowed and entire at its upper edge; the labrum is straight, and without the usual

concavity in the middle, besides being extremely short, with the deflexed apex short

and obtuse; the vertical edge of the semiovate concave clypeus is thickened and

projects in front considerably beyond the mouth; and, lastly, the hind tibie are short,

about two thirds the length of the tarsi, and dilated from base to apex. The antennal

club (especially in the male) is very long, slender, and curved, the mesosternum rather

narrow and declivous, the anterior tibie bidentate, and the mandibles and maxille short,

robust, and dentated. ‘The differences in labrum and tibie might justify the generic

separation of A. rhizotrogoides if they were found to hold good in the few species

Strigoderma (pars), Burmeister, Handb. der Ent. iv. 2, p. 515 (1844).

This genus, founded by Blanchard on a single Mexican species, is sufficiently distin-

guished from Anomala by its oblong form, convex thorax, and long quadrate clypeus,

which, added to the deep and close striation of the elytra, give the species a distinct

facies. There are, as usual in the subfamily, no very definite structural characters to

distinguish the genus from Anomala, Strigoderma, or Phyllopertha. One of the

principal is the long and robust, cheliform claw-joint of the anterior tarsi of the

males. Of the characters derived from the parts of the mouth on which Blanchard

in part founded the genus, that furnished by the labrum is the only one of importance.

This he terms “ obtectum,” which is scarcely accurate, as the upper basal part is plainly

visible, though forming only a narrow transverse piece ; and it is distinguished from the

same part in Anomala in being without trace of a central depression or emargination.

The head and thorax are black, opaque, the latter clothed with a very dense, erect,

and soft light-coloured pile. The elytra are pale reddish-brown, subopaque; in one

example only (captured by Mr. Salvin at Chinautla) are they variegated with black—a

broad fascia behind the middle, and a second spot on each side near the tip of the

scutellum. ‘The scutellum is like the thorax opaque, black, and coarsely shagreened.

The head, especially in the male, has the long, quadrate form and upturned edges of

the typical species; and E. moreletiana is undoubtedly congeneric with EL. mexicana.

As in many species of Anomala, of the A. micans group, the sharp ascendent edge of

the mesosternal epimera rises in front of the shoulders of the elytra so as to be visible

from above. This feature shows the close relationship of those forms with Epectinaspis

and Strigoderma. An example from Duefias is figured.

in many Anomale. The convexity of the hind part of the thorax and the form of the

clypeus (which is no doubt more pronounced in the unknown male) show that the

species belongs to Kpectinaspis.

A genus, so far as at present known, peculiar to America, and ranging far into the

northern temperate zone, as well as throughout the intertropical region as far south as

Tucuman. It is well represented in Mexico and Central America; and the numerous

species we have to add to the genus show a far wider range of sculpture, as well as form,

than was anticipated when the generic name was given. But, however diverse, they

resemble each other much more thar they do any of the varied forms of Anomala,

and the tumid ascendent mesosternal epimera afford a good distinguishing character

in cases of doubt. In all the species the males may be distinguished from the opposite

sex by the more attenuated abdomen, concave on its ventral surface, a difference which

is very rarely observable in the Anomale.

short, highly polished, elevated dorsal line or space near the base between the basal

ends of the two broad oblique discal sulci, which never fails in the large series

examined, also distinguishes the species. Blanchard’s phrase “ prothorace... .

not S. protea.

The thorax is almost evenly convex, without fovee or very distinct impressions, and

is wholly alutaceous, opaque, and pubescent. In comparing the large series of this and

the two preceding species the present appears to be generally of larger size and more

diverse in the colours of the elytra, the state of the typical S. marginata being exceedingly

uncommon. Rare examples occur which are partly intermediate, not only between this

and S. mexicana but also between S. intermedia and S. marginata, and prove that

they are all forms of one stock, barely segregated into species.

Distinguished by the dense and strong subrugose punctuation of the thorax; the latter

is without fovee or depressions, narrow, and subangularly dilated in the middle, with

porrect acute front and hind angles in the male, broader and less acutely angular in the

female, its colour being variable—sometimes wholly dark greenish metallic, but more

often tawny-red, like the elytra, with or without a green patch on its anterior part, the

curiously declivous lateral margins being sometimes yellow, but not the basal margin.

The under surface and pygidium and the apical margin of the propygidium are densely

clothed with long recumbent tawny-ashy hairs. The mesosternum is subvertical, slightly

tumid at the apex. The lateral margin of the elytra, in the female only, has an abruptly

formed, much thickened and vertically arcuated, wheal.

In Guatemala examples occur with the elytra lineated with fuscous.

from S. vestita. The sexual characters and sculpture are similar. ‘The thorax in

S. sall@i, however, is less elongated in both sexes, and the closely packed. punctures

are less confluent and confused; its colour also is always dark brassy-green or dull

cupreous—there is no example in the tolerably large series examined tawny-red in

The type specimens of Newman’s two species differ in sex, S. castor being a female

and S. pollus a male, the latter consequently with a narrower thorax ; they differ also

considerably in the thoracic punctuation—in S. castor it is coarse and subconfluent

with numerous irregular depressions on each side of the disc, besides the broad groove

along great part of the inner side of the yellow submarginal wheal. ‘The thoracic

punctuation is, however, very variable in this species in both sexes: in the numerous

series before me there are all gradations, and extremes go beyond the states of Newman’s

species; but the finest punctuation does not reach the nearly smooth thoracic surface

of Burmeister S. orbicularis. Rare examples occur, however, which partly connect

these two apparently distinct species and even S. castor with S. festiva.

Independently of the thoracic punctuation, S. castor differs from the nearest allied

species or subspecies in the shape of the clypeus, it being semioval or much narrowed

and curved from the base to the rounded apex, with the margin very slightly raised.

The yellow raised border is never absent from the thorax, the disc of which is generally

brassy-green, but sometimes rufo-testaceous, and the oblique depressions on each side are

seldom strongly marked. ‘The thorax is dilated considerably before the middle, and

the sides behind the angle are deeply sinuated to the hind angles, which are acute in

the male and rectangular in the female. Viewed from above the thorax is elongate

and narrowed in front in the male, but transverse-quadrate in the female. The elytra

have the suture nearly always dusky, and sometimes also the humeral callus, apical

being less densely clothed with cinereous pile and contrasting with the rest of the

uncovered portion of the abdomen by its brassy-black colour. ‘The anterior disc of the

elytra is much more strongly depressed.

large number of examples of both, and the absence of all trace of connecting varieties,

lead me to treat it as a distinct form.

Hab Nicaraava, Chontales (Belt); Costa Rica (Van Patten); Panama, Bugaba,

Volcan de Chiriqui (Champion).

A large number of examples. The black elytral markings of the male are strongly

developed only in Costa Rican specimens—in some the apical half is black, as well as

the scutellum and lateral patches; none of the males from Panama have more than

the suture, continued along the sides of the scutellum, and a lateral vitta, dusky.

The species is allied to S. colombica, Burm. The elytral strie are more deeply

impressed than in S. colombica, but less so than in S. castor and its allies; and there isa

further peculiarity in the occurrence of a rudimentary fourth stria between the suture

and the humeral callus, which is distinct for some distance from the base between the

fourth and fifth strie and in some females extends nearly to the apex.

A Costa Rican specimen is shown on our Plate.

Hab. Nicaragua, Chontales (Janson).

Two examples, females. This beautiful species differs but little in details of structure

from Strigoderma, although the peculiar sculpture, or lack of sculpture, and the

Rutela-like coloration seem to indicate a different generic type. The membranous

border of the elytra is well-developed, and the antenne are 9-jointed, though the fifth

joint is much longer than any of the rest, and the mesosternal epimera are tumid at

the sides and strongly ascendent. The most important differences are in the labrum,

the visible basal part of which is longer than in the Anomale generally, and has no

trace of median depression, but is straight and sharp-edged, and dips vertically in front

with its lower (or anterior) edge not visible; and in the mentum, which is in the same

plane as the ligula and longitudinally concave.

form, the genus Bola, from which the porrect, deeply divided labrum amply

distinguishes it. The clypeus is large and subquadrate, with much rounded anterior

angles, and separated from the forehead by a straight suture which is somewhat

inconspicuous owing to the dense sculpture.

Subfam. RUTELINA.

This subfamily corresponds to the “Sous-Tribu Rutélides vraies ” of Lacordaire, with

the exception of the genera Wacropoides and Heterosternus, and the greater part of his

Groupe “ Aréodides.” It excludes, therefore, those genera in which the head is

furnished with a frontal suture. The front edge of the labrum is deflexed in the

middle and in most cases closely folded under.

The insect on which this genus is founded has the appearance of a broad Anomala

or Huchlora, and the labrum is that of an Anomala; but the total absence of mem-

branous margin to the elytra, the frontal suture, and the 10-jointed antenne, remove it

from the subfamily to which Anomala belongs. Its place is evidently near Telaugis,

though the form of body and sculpture of the elytra give it an appearance totally

unlike that genus.

The base of the thorax has a similar widely-interrupted margin, and the anterior

vertical face of the clypeus slopes backward and forms a fold (highest in the middle) in

front of the head. But the fold is not so horizontal as in Telaugis, and is separated

from the surface proper of the clypeus by a deep and broad groove which surrounds

the three sides of the clypeus.

Ometis, Latreille, in Cuvier’s Régne Anim. iv. p. 554 (1829) ; Lacordaire, Gen. Col. ii. p. 344.

The sole character on which the genus Ometis is founded lies in the ascendent meso-

thoracic epimera. This is nearly as well marked in the typical species of Lagochile

(L. trigona) as in the type of Ometis ; the name, therefore, if the genus is to be considered

valid, becomes a synonym of Lagochile, and the majority of the species hitherto

LAGOCHILE. 263

ranged under the latter would in that case requirea new genericname. ‘The ascendent

mesothoracic epimera, however, are evidently not of generic significance, as they exist in

many Antichire, and the character is not corroborated by any other peculiar feature.

Lagochile is peculiar to Tropical America. Up to the present time eleven species

have been described.

In form and sculpture agrees exactly with L. circwmdata, from which it differs con-

stantly in colour and markings, the elytra and underside being wholly tawny-red, and

the head and thorax black, with the entire margin of the latter (sometimes interrupted

near the head), a dorsal line extending from the labrum to the middle of the thorax,

and the scutellum (or its borders only) tawny-red. The mesosternal process is formed

as described under ZL. circumdata, but the elytra are perceptibly more convex.

Burmeister gives a description of this species, which is very good, except as to the

emphasized convexity. In the numerous examples I have examined the elytra, though

varying considerably, show at most but little convexity of surface. Among the pecu-

liarities of the species is the continuity of the marginal groove of the thorax, which

extends at least to the hind angle, and sometimes passes it and runs for a short distance

along the basal margin.

Macraspis, § 1, Burmeister, Handb. der Ent. iv. 1, p. 345 (1844).

Antichira, Div. 1, Blanchard, Cat. Coll. Ent. i. p. 204.

The first division of Antichira seems to me to offer sufficiently well-marked and

numerous structural characters to merit generic distinction. It differs from Antichira

proper in the following points:—mandibles with the exterior edge rounded, unarmed ;

clypeus small, and, in the species where it is not concealed by the close sculpture,

separated from the forehead by a fine, though broadly interrupted, suture; labrum

porrect, horizontal; thorax with a large acute-angular basal lobe (the angles sharply

indenting the base of the elytra), and the basal margin on each side very deeply

sinuated to the acute and produced hind angle; and tarsal claws in both sexes simple.

Four species are known, from Tropical America, perfectly concordant in the above

characters *.

About 80 species of this beautiful and highly characteristic Tropical American genus

have been described. Its limits have been left in much uncertainty by authors who

have dealt with it; the grouping of its forms and those belonging to allied genera

leading to different results according as the general facies, the size of the scutellum, or

the dentition of the tarsal claws are taken as the chief points of distinction; and the

graduation from form to form greatly increases the difficulty. I propose here to limit

the genus to those species which have exteriorly bidentate mandibles, a more or less

large triangular scutellum, the thorax with truncated or sinuated medio-basal lobe, and

the mesosternal process well-developed. The mode of dentition of the tarsal claws is

treated as a specific or at most a minor group character.

The majority of our examples are distinguished from the A. tetradactyla (Linn.), from

Jamaica, by their narrower form, the thorax also being narrowed slightly from the base

forward, and the scutellum decidedly narrower. But rare individuals occur which are

scarcely distinguishable from Jamaica specimens in these respects. All, however, have

the pygidium finely strigose and punctulate throughout, whilst in A. tetradactyla this

segment is smooth on the basal half. Most Mexican examples have a fine submarginal

stria along the hind margin of the thorax on each side, of which there is no trace in

those from Guatemala. The whole insect is deep polished black. The closely allied

A. tristis (Casteln.) from Guadaloupe and St. Martin is distinguished by the numerous

smooth sulci of the elytra.

Sometimes found in numbers flying in the hot sun about the anona and other fruit

Hab. Panama, Chiriqui (Trétsch), Volcan de Chiriqui 2500 to 6000 feet (Champion).

A large number of examples were captured by Mr. Champion. The brighter green

individuals approach A. lucida in colour, but the majority are very dark, almost brassy-

black. In addition to the points of distinction mentioned above, it may be noted that

the conical apex of the pygidium in the male is much less elongated than in A. lucida.

In the hairy underside the species approaches the Venezuelan A. pubiventris (Blanch.) ;

but the latter is very densely clothed beneath and on the legs and pygidium with long

tawny hairs, and the upper surface is rather thickly punctulated.

The reddish-brown translucent examples which have given the name to the species

are apparently not the common form, the prevailing colours being rich brassy-green,

blue-green, and dark blue. The under surface is more or less hairy, but the strongly

inclined and clavate mesosternal process distinguishes the species from A. hertiventris.

It varies in size from 18—22 milim.

A specimen from San Geronimo is figured.

Glossy black, the elytra each with two vittee, and the lateral third of the thorax

(enclosing an elongate black spot) orange-yellow. The mesosternal process is horizontal,

upturned at the apex. The medio-basal lobe of the thorax is almost imperceptibly

produced and very wide and slightly arcuate-sinuate.

268 LAMELLICORNIA.

This genus is founded to include a considerable number of species, homogeneous in

facies as well as in structural characters, which differ constantly from Antichira in the

form of the mandibles, from Thyridiwm in the size and shape of the scutellum (which

is one fourth the length of the elytra and triangular with flexuous sides), and from

Chlorota (sensu Lacordaire) in the well-developed mesosternal process. In the trun-

cated basal lobe of the thorax, also, it differs from the two latter genera, which are well

characterized by the same part being somewhat strongly rounded over the base of the

scutellum.

possess. One of the latter is figured.

Ent. Soc. Lond. 1881, p. 545.

Fourteen species of this genus have been described, all restricted to Tropical America.

Its distinguishing characters are :—mandibles rounded (or very slightly sinuated) and

unarmed on their outer edge, thorax with rounded medio-basal lobe, and the scutellum

small and heart-shaped, or with curvilinear sides.

genera of the subfamily, to Tropical America. I follow Lacordaire in limiting it to

one only (II. B.) of Burmeister’s four sections, in which the mesosternal process is very

short and the scutellum small and cordate, but eventually the genus will have to be

further subdivided.

In the male the thorax is broadly margined with yellow, and the elytra are quite

smooth; in the female the sides of the thorax only (sometimes narrowly) are yellow,

and the elytra are punctate-striate, with the sides and apex thickly punctured. These

differences are found in individuals from all the above localities.

We figure a specimen from Nicaragua.

insect on which it is founded is no doubt that mentioned by Lacordaire in a note on

the genus Chalcentis (Genera Col. ili, p. 353).

An elongate-oblong reddish-testaceous species, having three black spots on each elytron

in the same position as those of the common North-American P. punctata, but the spots

are much smaller and sometimes absent. The elytra are somewhat flattened and dull

silky-shining owing to the extremely fine punctate-granulate sculpture, and the sutural

apex is produced into a distinct spine. The upper surface (including the crown) is

unicolorous, except for the slight metallic tinge of the head, thoracic margins, and

scutellum. ‘The under surface is dark brassy, punctate-shagreened, and clothed with

grey hairs, the legs being testaceous-red, rarely metallic.

We figure an example from Tlacotalpam.

In colour of body and legs this variety much resembles P. virescens, especially the

Guatemalan form, the latter, however, is more elongate and more brilliantly relucent,

besides wanting the brassy-green bilobed spot on the vertex. The head, moreover, is

smaller in the present species, and the clypeus in the male very different, being

triangular, and not rounded.

5. Pelidnota virescens. (Tab. XVI. fig. 2,2.)

Pelidnota virescens, Burm. Handb. der Ent. iv. 1, p. 403*; Blanch. Cat. Coll. Ent. 1. p. 212°.

Hab. Mexico }2, Ventanas in Durango, Jalapa, Tacambaro (/dge), Ciudad in Durango,

Presidio, San Blas (Yorrer), Cuernavaca, El Camaron, Vera Cruz (Sa//é).

This species is distinguished by its testaceous-yellow colour (clypeus concolorous) and

its brilliant glassy silvery-green lustre. But it varies much in outline and convexity

and sculpture, the elytra especially, which in the typical state are punctulate-striate

with convex interstices, being sometimes smooth with very fine striae and flat inter-

stices. In the typical form the underside of the body and pygidium are brassy-green,

and the legs testaceous, more or less inclining to brassy-green on the femora and tibie.

In some localities varieties occur which, although not very constant, depart so much

from the type as to merit separate mention :—

Two examples (male and female, the female duller in colour) from Cayo have

smoother elytra than others of the same colour from Guatemala, but not smoother than

individuals from Acapulco, and less smooth than one from Vera Cruz. Gradations

exist between them and the var. aurescens.

6. Pelidnota cupritarsis.

P. luecde quam proxime affinis. LElongata, flavo-testacea vix eneo-tincta, corpore subtus pedibusque viridi-

eeneis his rufo-translucentibus, tarsis lectissime igneo-aureis.

Long. 26-27 millim. 9°.

Hab. Panama (coll. Bates).—Cotomsia, Sierra Nevada de Santa Marta.

Very closely allied to the common P. lucida of Venezuela, with which it has in

common the immarginate base of the thorax, a character which would remove it not

only from Pelidnota, but from the group to which Pelidnota belongs, if it were

necessary to adhere to a single feature, in violation of all other signs of true affinity.

It differs from P. lucida in the absence of eneous gloss, except on the sides of the head

and thorax, and in the rich coppery-red tarsi. The under surface of the body, legs, and

pygidium are rich metallic green, and, except in the middle of the body, strigulose-

punctulate. ‘he clypeus is subtriangular ( 2 ), with the sides sinuated and the apex

reflexed and truncate or obtuse. The thickened margin of the elytra extends to within

a short distance of the sutural apex, which latter is simple, rectangular, or obtuse.

The species answers in some respects to the imperfect description given by Latreille

of his P. polita, from Cuenca in Peru. —

Distinguished by its very elongate-ovate form; the elytra gradually flattened behind,

with long and sharp sutural spine, and the thickened reflexed lateral margins

continued nearly to the apex. In Mexico and Guatemala the colour is almost always

testaceous-yellow, with strong brassy or golden reflections, but some Guatemalan

examples are rich dark coppery with brassy-green reflections. The legs are coppery

or reddish, with brassy femora. An example from Cordova is figured. In the southern

parts of our region, according to the few examples received, the species is represented

by a tolerably well-marked local variety :—

Boucard, Proc. Zool. Soc. 1875, p. 117.

Twenty-two species of this superb genus have been described. It is highly charac-

PLUSIOTIS. Qik

teristic of the Central-American region, including the southern borderlands of the

United States. I have seen two species only (one of which belongs to the burnished-

metallic group of the genus*) from South America. P. leta, Sturm (=P. psittacina),

the type specimen of which is in the Sallé collection, is a Mexican species recorded

erroneously from Chili.

Hab. Costa Rica (Van Patten), mountains of Candelaria 5000 feet (Boucard ').

Most examples are smaller than P. victorina (27-32 millim.), to which it approaches

in the dark brick-red colour with coppery tinge of the underside, and in the sculpture

of the elytra. The whole upper surface is apple-green, with yellowish reflections.

The pygidium in the male is strongly convex near the apex, in the female convex in

the middle with retuse compression on the sides. The mesosternal process is subelon-

gate and acutely conical as in P. victoria.

I know this species only from the description and figure given by Boucard ; the

following is a variety, or possibly the typical form of it :—

Long. 28-33 millim.

Hab. Nrcaraaua, Chontales (Belt); Panama, Bugaba, Volcan de Chiriqui 4000 to

6000 feet (Champion).

Eighteen examples, offering no differences in colour. ‘The usual secondary sexual

characters in clypeus, anterior claws, and pygidium seem to be very slight in this

species, though small differences in the outline of the clypeus show that we have both

sexes. In all examples the pygidium is convex near the apex, and more or less

culminate along the middle.

One of our examples bears a label in M. Boucard’s handwriting “ Plusiotis aurora,

var., Boucard.” This species, therefore, is that which he describes (Proc. Zool. Soc.

1875, p. 119) as a doubtful green variety of his P. aurora. The specimen figured is

from the Volcan de Chiriqui. ,

Plusiotis marginatus, Waterhouse, Ent. Monthly Mag. viii. p. 5°.

Hab. Panama, Chiriqui1 (Zrétsch), Volcan de Chiriqui 2500 to 6000 feet (Champion).

The pygidium is strongly convex near the apex in both sexes. ‘The males are distin-

guishable by the larger claw of the anterior tarsi being much longer and broader than

in the females.

5. Plusiotis resplendens.

Plusiotis resplendens, Boucard, Proc. Zool. Soc. 1875, p. 119, t. 28. fig. 5°.

Hab. Cosra Rica (Van Patten, Rogers), near San José (Boucard+); Panama, Volcan

de Chiriqui 4000 to 6000 feet (Champion).

Twenty-five examples. In this pale golden, very highly polished, almost silvery

species the clypeus is a little narrowed near the apex in both sexes, and the apical

margin reflexed and often distinctly sinuated. It is remarkable for the form of the

mandibles, which show a tendency to reversion to the Pelidnota type, for their outer

edge is not broadly rounded, but more or less sinuated, and in some examples very

obtusely bidentate. The pygidium is clothed with long, stiff, tawny hairs on its posterior

half; it is slightly more convex in the male than in the female, but has not the convex

protuberance near the tip, which is so pronounced in P. awrora, var. chrysopedila, and

P. marginata. The larger anterior claw of the male is much longer and broader than

in the female. The size ranges from 22 to 27 millim.

PLUSIOTIS. 279

This and other species of Plustotis (as well as Thyridium and various Antichire) were

met with flying in the hot sun about the tops of trees on the margin of a lagoon in the

dense forest ; numerous living and dead specimens of these (as well as vast numbers of

Dynastide and other Lamellicornia) were also found submerged in the water or cast up

on the banks (Champion).

6. Plusiotis optima. (Tab. XVI. fig. 10.)

Elongato-ovata, prope elytrorum basin valde convexa fere gibbosa, politissime aurescenti- vel igneo-cuprea, elytris

Long. 26 millim. ¢.

Hab. Costa Rica (Van Patten).

One example only, from its short, squarely emarginated, apical ventral segment

undoubtedly a female. The species differs in many respects from all its congeners, and

from the nearly immarginate base of the thorax might be considered to approach

Thyridium or Ptenomela more nearly than any genus of the Pelidnota group, but the

marginal sulcus near the posterior edge of the thorax is scarcely impressed in other

species of Plustotis. The rich red-golden hue of the upper surface and mirror-like

polish make it one of the most conspicuous species of a genus remarkable for metallic

splendour. |

7. Plusiotis batesi.

Plusiotis batesi, Boucard, Proc. Zool. Soc. 1875, p. 119, t. 28. fig. 6*, and 1878, p. 293”.

Hab. Costa: Rica (Van Patten), Volcan de Irazu 1?.

Twelve examples, both sexes. The clypeus in the male is obtusely rounded in front,

and in the female a little more elongate and produced, with the slightly reflexed apical

margin more or less sinuated. The mesosternal process is rather short, but acute, and

not conical or thick vertically. It is a large (32 millim.) and somewhat narrowly

oblong species, with relatively narrow thorax widened before the middle. The colour

in the fresher examples is more silvery than in P. resplendens, but less purely white

than in P. chrysargyrea.

Hab. Costa Rica, Candelaria Mountains °.

Six examples; all of a silvery hue, like a ball of mercury, to which Sallé aptly

compares it; the sides of the breast beneath and legs being of the usually smooth

subopaque pinkish-clayey hue characteristic of the undersides of all the allied species,

but with the centre of the sternum (including the hind trochanters) and abdomen

greenish-silvery polished and the tarsi rich violet. The variety described by Boucard

is not contained in our collections.

The specimen figured is from the Volcan de Chiriqui.

Plusiotis badeni, Boucard, Proc. Zool. Soc. 1878, p. 294, t. 16. fig. 2°.

Hab. Mexico, Orizaba (Sal/é).

A small, rather oblong species, with a roughly granulate-rugose pygidium, a burnished

silvery apical callus, and a long. and slender sternal process. ‘The elytra are somewhat

regularly punctate-sulcate, with the alternate interstices (four on each elytron) irregu-

larly punctured, as in P. awripes. The sides of the thorax are broadly rosy-red.

10. Plusiotis lacordairei.

Plusiotis lacordairei, Boucard, Proc. Zool. Soc. 1875, p. 122, t. 28. fig. 4°.

Hab. Mexico, Juquila1 and Las Peras in Oaxaca (Sal/é).

Very closely allied to P. badeni, but the silvery apical callus is larger and still more

brilliant and the sides of elytra and body have a silvery lustre; the sternal process is

only about one half the length, though very acute; and the pygidium is much less

roughly punctate-rugulose. The thorax is destitute of red lateral vitta. Three

examples, including both sexes.

11. Plusiotis sallei.

Plusiotis sallei, Boucard, Proc. Zool. Soc. 1875, p. 128, t. 28. fig. 3°.

Hab. Mexico, Orizaba! (Sallé), Jalapa (Hoge).

Nearly allied to the two preceding, but larger and (in the female) broadly ovate, with

remarkably long tapering clypeus ; the pygidium thickly punctured, without ruge. The

sternal process is nearly as long as in P. badent and the sides of the thorax are rosy-red

as in that species. The apical callus of the elytra is scarcely shining. Three examples,

all females.

Hab. Muxico! 734,

The general form of this species is not described by Gray nor Burmeister, but they

note the convex, alternately punctured and smooth, interstices of the elytra, and golden-

green tarsi. Boucard, who states that he possesses Gray’s type-specimen, describes its

form as “ oblongo-ovata,” and decides, after careful examination of authentic examples

of both species with the aid of Mr. C. O. Waterhouse, that it is specifically distinct

from the following, with which it was united by Burmeister.

Plusiotis amalia, Burm. Handb. der Ent. iv. 1, p. 422.

Hab. Mexico! (Sallé, ex coll. Sturm).

There are two examples of this species in the Sallé collection, named by Sturm with

the synonym on the label in his handwriting “ P. auripes, Gray.” Sturm therefore

considered his species to be the same as the earlier described P. auripes. The insect is

33 millim. long, of elongate oblong shape, even in the female, and wholly clear apple-

green, slightly metallic on the underside, epipleure, and legs, the tarsi more ‘brilliant

metallic green. The elytra are irregularly punctured on the alternate interstices

(second, fourth, sixth, and eighth) and minutely punctulated throughout ; the head and

thorax are somewhat closely punctured, with the interstices minutely punctulated; and

the pygidium punctulate-strigulose. The sternal process is very short, slightly projecting

and conical.

The type-specimen of P. eta (Sturm) is contained in the Sallé collection; it is

evidently a small and somewhat deformed example of P. psittacina. According to the

label, Sturm regarded it as synonymous with P. amalia, Burm., and as such it has

been classed by subsequent authors. Sturm gave the locality as ‘‘ Brazil,” Burmeister as

‘“‘ Valparaiso”; but the insect is most certainly Mexican. It is to be remarked that

Burmeister placed his P. amalia in a different section (sternal process very short) of the

genus from P. auripes (sternal process projecting as a strong cone beyond the middle

coxe). In both of Sturm’s species, P. psittacina and P. leta, the sternal process is of

the same length, very short, and only slightly projecting.

282 LAMELLICORNIA.

More than fifty examples, offering scarcely any differences of form or punctuation. It

is a broadly-ovate species, the outline being due to the flattened expansion of the sides

(including the marginal rim) of the elytra ; the convex interstices are smooth, except the

second, and towards the base the sixth, both which are irregularly punctured. The

pygidium is minutely punctured, and not closely strigulose as in P. psittacina; and the

sternal process is more than twice as long as in that species and conical. Blanchard

described P. costata from a singular colour-variety, clayey reddish-tawny, which proves

to be a rare exception; the great majority of our specimens being apple-green,

with the apical callus concolorous, and the thickened margins of the elytra and the

tarsi sometimes golden. Intermediate examples occur in which the upper surface

has strong yellow reflections. The pygidium in the female is flattened to the apex,

in the male it is evenly convex. The size varies from 25 to 35 millim.

15. Plusiotis chloreis. (Tab. XVI. fig. 16, ¢.)

P. costate proxime affinis, sed minor, oblonga, thorace postice angustiore angulisque anterioribus valde porrectis,

Long. 25 millim. ¢ 2?

Hab. Mexico, Volcan de San Martin (Sal/é).

The second and sixth elytral interstices are, nearly as in P. costata, irregularly

punctured towards the base. This mode of sculpture and the much longer sternal

process distinguish the species from P. psitéacina, which it resembles in the oblong

form of the body. The female example, very imperfect, is from Orizaba (Sal/é).

16. Plusiotis prasina.

Hab. Mexico 1, Orizaba, Yolos (Sad/é).

Three examples, including, according to Boucard, a type-specimen. Length 30

millim. ¢ &.

Closely allied to P. laniventris, the sides of the abdomen and the pygidium in the

male thinly clothed with long hairs. P. prasina differs, however, from that species in

the outer side of all the tibiz being smooth and not scabrous, and in the entire upper

surface, but especially the elytra, being much more finely and smoothly punctured,

though in both the species the punctuation extends over the whole elytra. The punc-

tured strice are scarcely impressed. ‘The female in both species has the same broadly-

ovate outline, with the sides broadly expanded and the outer margin flexuous or

arcuated. The legs are of a pinkish-clayey hue, the femora greenish, the tarsi

the pubescence of the sternum is also longer and denser than in the allied species.

The elytra are coarsely and rugosely punctured throughout and furrowed with deep

An oblong species of dark-green colour with strong metallic gloss, especially on the

margins, scutellum, abdomen, and pygidium; the elytra punctulate-sulcate; and the

head (especially the clypeus) smaller than in the allied species. ‘The sternal process

Lacordaire, Gen. Col. i. p. 359.

Like Plusiotis, a characteristic Central-American genus, containing species of large size

and beautiful colours ; but differing as regards distribution in being confined to Mexico.

The characters which distinguish it from Plusiotis are almost solely derived from

the males, this sex having enormously developed hind legs, the females being Plustotes

in everything except the convexity or protuberance of the hind part of the postpectus

and the inner end of the posterior coxe—a peculiarity developed in far greater degree

in the male, but transmitted in part to the female.

Hab. Mexico, San Luis Potosi}, Orizaba (Sallé), Misantla, Jalapa (H6ge).

The males vary much in size, and correspondingly in the convexity or protuberance

of the hind part of the postpectus and the inner condyle of the coxe to which the

monstrous hind femora are articulated. The condyle, the trochanters (at least their

outer sides), and the anterior edge of the coxe are blackish or dark green in both sexes ;

and in the female the epipleural fold of the elytra terminates abruptly, forming a short

I cannot but consider the following to be varieties of C. macropus, but they are

varieties of singular interest as resting chiefly on modifications of the sexual characters,

and at the same time local.

The upper surface in this distinct species is thickly punctured and less shining, the

elytra very closely punctured, with finer punctures intermixed, and scarcely any trace

of strie. ‘The underside varies in colour, but is much more brilliant than in C. macropus,

wholly rich red-coppery, or the abdomen silvery and sometimes dark near the base. In

the single female from Ciudad the head, femora, tibie, and pygidium are tawny-vermilion

with a metallic tinge. ‘The underside and pygidium are clothed with long hairs, which

are denser in the female. The epipleure in the female taper gradually nearly as in

C. macropus, var. adolphi, but without expanded upper margin, and they reach only a

little beyond the middle of the elytra instead of nearly to the outer apex.

Subfam. HETEROSTERNIN 4.

MACROPOIDES.

Macropoides, Guérin, Rev. Zool. 1844, p. 262 ; Lacordaire, Gen. Col. 11. p. 360.

Macropnus, Horn, Proc. Acad. Phil. 1866, p. 397.

This genus, with Heterosternus and its allies, forms a distinct subfamily (indicated

by Horn in defining the genus Macropnus), distinguished from the Ruteline by the

flexuous and fine frontal suture, and from the Areodine by the form of the clypeus

(strongly narrowed from the base and obtusely trapezoidal) and of the mandibles (the

outer apical angle bent upwards and prolonged into a tapering and ascendent tooth

projecting beyond the margin of the clypeus); in repose the ascendent apices of the two

mandibles lie parallel and close to each other. The form resembles that of the

mandibles in Rutelisca, and is an exaggeration of that usual in Parastasia. ‘The base

of the thorax is generally immarginate ; but in this respect Heterosternus is peculiar,

the marginal sulcus being deeply impressed except in the middle, where it is faint

or interrupted. The males in some of the species have the same enormous develop-

ment of the hind legs, with a corresponding protuberant postpectus and inner end of

the coxe, asin Chrysina. ‘The major tarsal claw in all the tarsi of both sexes is forked,

and the postcoxal process of the prosternum short and triangular, not bent and continued

horizontally between the coxe as in Pelidnota and its allies.

Three species of Macropoides are known, all peculiar to the Mexican and Central-

American fauna.

The clypeus is rather longer and more narrowed than in MM. nietot, and rather

3. Macropoides crassipes.

Macropnus crassipes, Horn, Proc. Acad. Phil. 1866, p. 897; Trans. Am. Ent. Soc. 1. t. 3. fig. 7’.

Hab. Honduras !.

The incomplete and inaccurate description of Macropotdes given by Guérin and

Lacordaire, the latter by placing it near the Pelidnote and leaving it to be inferred that

it has the same characters as that group, led Dr. Horn to institute the genus Macropnus

on a large species from Honduras, which he informs me he now believes to be congeneric

with V/. nietoi. The species is not represented in our collection.

4, Macropoides (?) ——?

Hab. Nicaraeva, Chontales (Belt).

A single example ofa species probably belonging to this genus, but being a femaie

HETEROSTERNUS.

1, p. 411; Lacordaire, Gen. Col. iii. p. 360. |

Two species only are known of this genus, remarkable for its elongate form and the

sreat length of the hind legs in the male with greatly elongated tibie. ‘The postpectus

and condyles of the hind coxe are still more strongly developed and protuberant than

in Chrysina macropus; but the coxal plate is much widened towards the supports of

the femora, which latter are extremely elongated and of uniform width. The clypeus

and mandibles are shaped almost exactly as in Macropoides nietoi. In the female the

epipleuree terminate at the level of the hind coxe, where the elytra are angularly dilated.

H. buprestoides in the elytra not being narrowed and prolonged at the apex, and in the

hind tibiz being strongly curved and densely fringed inside with fulvous hairs.

Mr. Champion obtained one example only, a male, on the Guatemalan Pacitic slope.

A female specimen from Chiriqui, resembling an ordinary Pel¢dnota in form and many

years in my collection without a name, almost exactly resembles the Guatemalan

male in colour and sculpture; it differs only in the suture and outer margin of the

elytra, as well as the head and thorax, being narrowly edged with black. The male

example from Los Diamantes is figured.

COTALPA.

Cotalpa, Burmeister, Handb. der Ent. iv. 1, p. 423 (1844); Horn, Trans. Am. Ent. Soc. 1871,

p- 338.

A genus hitherto recorded only from temperate North America; six species are

known, chiefly from the southern and western States. The two following have a longer

and more acutely rounded clypeus than in the typical species of the genus, but not

much more so than in C. ursina, and they differ further in the major claw of all the

tarsi, in the male, being cleft (unequally and narrowly) at the apex.

1. Cotalpa nigro-znea. (Tab. XVI. fig. 22, 3.)

Anguste ovata, capite, thorace pygidioque viridi-eneis, politis, elytris corpore subtus cum pedibus nigris viridi-

One example only. The long and dense pale tawny villosity of the under surface,

pygidium, &c. is exceedingly fine and silky, differing much from the shorter and stiffer

rusty-red, but still very dense, hairs of C. nigro-enea.

PARACHRYSINA.

Chrysina (?), Thomson, Archiv. Ent. i. p. 148 (1857).

The small species, C. truguii, which Thomson doubtfully referred to the genus

BIOL. CENTR.-AMER., Coleopt., Vol. II. Pt. 2, August 1888. alle

290 LAMELLICORNIA.

Chrysina, differs from the group to which Chrysina belongs by the distinct frontal suture.

This suture is flexuous; the clypeus is semiovate (in the female more quadrate), with the

margins much reflexed ; the mandibles with entire (rounded) outer edge ; and the thorax,

margins, and the under surface of the body villose. In short it has all the characters

of the Areodine, with the important peculiarity that it has 9-jointed antenne, in

which it differs from all other Ruteline. The males have greatly enlarged hind legs,

with broad, interiorly-flattened femora and tibie, the inner apex of the latter prolonged

and acute, and the trochanters with a long, free, hook-shaped apex. The forehead in

the male is flattened, forming a semi-ovate sloping disc. ‘The mesosternum in the male

is prominent between the middle coxe, and conical but scarcely projecting ; in the

female depressed. In the female the forehead is simple, and the hind legs normal,

except that the apex of the trochanters is free for a short space and the inner apex of

the tibie is slightly produced. In both sexes the tarsal claws are very long and acute,

and all are simple; they are very unequal in length, and the tarsal joints are short and

compact as in all true Rutelide, so that there is no ground for referring the genus to

the Melolonthide as has been suggested. In the Sallé collection the species bears the

name of Plectris truquit. |

1. Parachrysina truquil. (Tab. XVI. figg. 23, ; 24, 2.)

Chrysina (?) truguii, Thomson, Archiv. Ent. i. p. 148, t. 10. fig. 4°.

Hab. Mexico (Truqui+), Morelia (Sallé), Yautepec (Hoge).

The male is more ovate than the female, and differs from it in colour and punctuation,

the thorax and elytra being fulvous, the former finely punctured and with an wneous

and smooth dorsal vitta; in the female the thorax is strongly punctured and brassy-

green, with the side-margins broadly fulvous. The size varies from 11 to 15 millim.

BYRSOPOLIS.

Byrsopolis, Burmeister, Handb. der Ent. iv. 1, p. 425 (1844).

A genus hitherto known only from tropical South America, whence four species

have been described. They seem to be perfectly congeneric with Burmeister’s

typical species (known to me only by the description), with which they agree in the form

of the maxille, and especially in the slender tarsi and tarsal claws; the peculiar

form of the labrum is not mentioned by Burmeister—in our species its upper surface

is entirely concealed under the clypeus. ‘They approach the Cyclocephaline, especially

the genus Democrates, from which the shorter and closer-jointed hind tarsi chiefly

distinguish them and justify their retention in the Rutelide. This at least applies

to the first species, in our two examples of the second the tarsi are wanting. ‘The pro-

sternum has a broad, scarcely ascendent, postcoxal process ; the mesosternum is simple.

BYRSOPOLIS.—PHALANGOGONIA. 291

Subfam. ANOPLOGNATHIN ZL.

PHALANGOGONIA.

Phalangogonia, Burmeister, Handb. der Ent. iv. 1, p. 451 (1844).

A genus, so far as at present known, peculiar to Mexico and Central America.

Three species have been described.

1. Phalangogonia obesa.

Phalangogonia obesa, Burm. Handb. der Ent. iv. 1, p. 452°.

Hab. Mexico 1, Chinantla (Sal/é).

Burmeister mistook the example of this species on which he founded his genus for a

male, and hence gave erroneous characters to Phalangogonia and to the subfamily to

which it belongs. It was evidently a female, as the male has robust tarsi and claws, and

the anterior angles of the clypeus produced and dentiform, as in many of the Australian

Anoplognathine. The three examples of the species in the Sallé collection vary much

in colour, and one isa male. Besides the acutely-dentated angles, the arcuated fore

border of the clypeus is strongly reflexed ; and the robust major claw in all the tarsi is

not forked as in the male, nor properly speaking cleft, the upper part of the divided

2 PP2

292 LAMELLICORNIA.

tip being very spiniform and much shorter than the lower part. The hindmost tarsi

only have a brush of stiff fulvous hairs beneath the first two joints.

The thorax is rather strongly punctured, quite strongly and closely so towards the

sides; the lateral margin, from the dilatation to the anterior angles, is greatly

decreased in thickness, and the anterior angles are acute. The elytra are finely and

sparsely punctulated, but vary somewhat in this respect; the coste are indicated by

punctured lines, and the posterior limb is closely and irregularly punctured; the

sutural apex is not produced. The legs, including the tarsi, are red. The pygi-

dium is subopaque, finely alutaceous or vermiculate-strigulose, without mixture of

piliferous punctures.

2. Phalangogonia sperata.

Phalangogonia sperata, Sharp, Journ. Linn. Soc., Zool. xi. p. 134°.

Phalangogonia stipes, Sharp, loc. cit.*

_ Hab. Cuytran America’; Nicaraeua ? (Sal/é), Chontales (Janson); Panama, Volcan

de Chiriqui 4000 to 6000 feet (Champion).

A large number of examples.

Differs from P. obesa (both sexes) in the much finer and sparser punctuation of the

thorax and in the lateral margins of the same being continued of equal thickness to the

anterior angles, which latter are obtuse, sometimes rounded; also in the sutural apex

of the elytra having a distinct spiniform tooth, and in the pygidium being very

minutely strigulose and sprinkled with larger piliferous punctures. ‘The male differs

from the same sex of P. obesa in the three basal joints of the hindmost tarsi and two

of the middle tarsi being clothed with a brush of fulvous hairs; it has similarly

robust and very unequally cleft major tarsal claws, and the clypeus is acutely produced

at the anterior angles, but the front margin is much straighter and scarcely arcuated.

The colour varies little on the upper surface, but on the under all gradations exist

from uniform fulvo-castaneous to black, the metasternum sometimes and the abdomen

at others only being black ; the last-mentioned (described as the colour of P. stipes by

Dr. Sharp) is most prevalent in Chiriqui.

Examples cccur at Chontales with black tarsi (the abdomen and sternum variable),

but I can detect no structural difference between them and the others.

Long. 20-22 millim.

Hab. Guatemaa, Cerro Zunil 4000 to 5000 feet (Champion).

Among the numerous examples examined no sexual differences can be detected. In

all, the major claw is forked at the apex in all the tarsii Some examples, which may

be males, have a rather shorter and more quadrangular clypeus than the others.

PLATYCQCELIA.

Platycelia, Burmeister, Handb. der Ent. iv. 1, p. 452 (1844).

A genus characteristic of the elevated regions of tropical South America, whence

twelve species have been described and many more exist unnamed in collections.

Hab. Muxico, Coatepec (Flohr); Costa Rica (Van Patten), Volcan de Irazu 6000 to

7000 feet (Rogers); Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion).

In colour and sculpture this species answers to the description of P. nervosa, Kirsch ;

but it evidently belongs to a different section of the genus, being of oblong form with

the convexity of the elytra continuing to the apex, Kirsch’s species being widened and

flattened behind. ‘The prominence of the shoulders is variable ; in some few examples

they are rectangular—this is the case with the single Mexican specimen sent to me by

Mr. Flohr. I have examined about fifty examples.

Mr. Champion found a large number of this species about the banks of a lagoon in

the dense forest: these had no doubt been blown into the water by the wind, many

being submerged or dead. A specimen from the Volcan de Chiriqui is figured.

SPODOCHLAMYS.

Spodochlamys, Burmeister, Handb. der Ent. iv. 2, p. 529 (1855).

Two species of this peculiar genus have been described, both from tropical South

America.

1. Spodochlamys cupreola. (Tab. XVII. fig. 10.)

more nearly approaches the form existing in C. fuliginea, in which, however, the upper

Cyclocephala, § 2 (Cyclocephale acute), Burmeister, Handb. der Ent. v. p. 39 (1847) (partim).

This genus has been too hastily rejected by authors subsequent to Erichson. Its

structural differences from Cyclocephala are of much significance. The labrum is

detached and inclined from the roof of the mouth, instead of being hidden as in

Cyclocephala with at most a very short margin exposed under the clypeus, and its apex

in the typical species is toothed; and the ligula is divided into two narrow lobes with

a narrow depression at its base extending far down the mentum.

These characters, though the form of the mentum was incomprehensibly misstated,

apply to Erichson’s type, A. scarabwoides, and to C. ustulata and C. humeralis of

Burmeister, but not to C. ocellata and C. maculata, which the latter author includes

in the same section. They apply also in all probability to A. lutea of Erichson, and to

A. jamesoni and A. crassimana of Murray, and without doubt also to C. manca of

Leconte. The acuminated clypeus and the narrow pointed mandibles bent upwards

from the edge of the clypeus are characters less distinctive of the genus, being shared

by species of the first section of Cyclocephala ; the clypeus is inconstant in shape, that

of the female of 4. guadripunctata being obtusely semiovate.

In specimens from southern localities the black spots of the elytra appear to be two

only in number, and small ; in those from Chiriqui the spots are often greatly developed

and increased in number, forming black streaks near the suture and sides and on the

disc; in some examples the whole disc of the elytron is black. The hair-fringe beneath

joints 1-4 of the hinder tarsi is dense but not very long. ‘The apical tooth of the labrum

is well-developed.

In the female the marginal callus of the elytra is extremely prominent, and forms a

projecting lobe.

species by Sturm in the Sallé collection and in his published catalogue.

The excellent description of Burmeister renders it easy to identify this species as

regards the male. The female may be distinguished from the same sex of the allied

species of similar shape and colour by the form and position of the elytral callus, it

being situated much behind the middle, and the margin near it is strongly sinuated and

depressed, the depression terminating behind with the projecting angular end of the lower

edge of the epipleural fold.

only definite character which separates the species from C. signata. The three examples

before me are females, which renders more difficult the determination of the species;

the one from Ecuador, however, exactly agrees in colour with Burmeister’s description.

The elytral callus is on the dilated margin, and near to the outer apex; close to it the

surface is depressed, and anterior to it the margin is thickened.

Hab. Mexico, Orizaba, Chiapas (Sallé) ; Nicaraeva (ea coll. Cutter).

Two Mexican specimens in the Sallé collection are labelled C. stictica, Burm., from

the other male examples of which in the same collection they differ in the broader,

obtusely-square form of the clypeus, and in the absence of apical sinuation, and the

fine and close sculpture, which renders the surface of the clypeus opaque. In these

respects the species comes nearer to the South-Brazilian C. variabilis, Burm., from

which in fact C. detecta differs only in the more broadly rounded thorax, the broader

clypeus, and the more distinctly black-edged elytral suture. From C. segnata it differs

in the more ample clypeus and fine scattered punctuation of the disc of the thorax,

besides being a larger insect. The male is further distinguished from the corresponding

sex of both C. variadilis and C. signata by the third and fourth joints of the anterior

tarsi being smooth, and not finely strigose.

We figure an individual from Chiapas.

A good series of examples. Burmeister placed this species in a section far apart

from that to which he referred C. signata and its allies, on account of its sinuated

clypeus. This single character, which in some examples is only very slightly developed,

ought not, I think, to outweigh the other numerous signs of close affinity. The lateral

callus of the female is large and wholly superficial, leaving the elytral margin con-

tinuous and normal. The major claw in the male fore tarsi is entire.

castaneous. In the darker examples the thorax is red. The hind margin of the

thorax has a continuous, deeply impressed groove. The marginal callus of the elytra

which latter is thickened (but straight) for a short distance.

Among the numerous unicolorous testaceous species with black crown, this is

distinguished by its semi-ovate clypeus, variable in size, but smaller and relatively

narrower than in C. signata, with the front edge sometimes almost obtusely truncated,

but reflexed and without trace of emargination. The thorax is relatively much smaller

than in C. signata, but the sides and hind angles are similarly rounded. ‘The upper-

side is light yellowish, the underside generally more rufous. The male has long hind

tarsi with long claws ; the female is distinguished from the same sex of the allied species

by the lateral margin of the elytra a little behind the middle being dilated, forming a

lobular projection, near which the surface has a slight callosity. This is probably what

Burmeister means by his phrase “ Das weibchen zeigt de schmale randschwiele recht

deutlich.”

The females of this species are readily distinguishable from those of the preceding

by the lateral margin of the elytra being simple, like that of the male, except for the

rather more thickened edge ; there is no trace of the slight lobular projection or surface-

callus. The males show no constant difference: all that can be said is that their

general form is more ovate, and the hind tarsi, with their claws, when very attentively

compared appear to bea little shorter. The colour is the same, but a good proportion of

examples, especially from Guatemala, are very dull castaneous on the underside. The

punctuation of the whole upper surface varies in both species, but it is nearly always

very fine, and the sides of the forehead and thorax show no trace of the larger punctures

which are so conspicuous in C. signata and its immediate allies. The pygidium in both

species is glabrous and nearly smooth; but in C. sororta it is generally more highly

polished and freer from punctuation than in C. mutata.

The species must be closely allied to the Jamaican C. cerea, Burm., but the descrip-

tion of the latter equally well applies to C. epistomalis.

Female examples agree exactly with others of the same sex, with which I have

compared them, from the Amazons and South Brazil. The lateral margin of the

elytra in the female is sinuated below the middle, followed by a dilatation, which

eradually subsides behind, and there is an elongate narrow callus, sometimes only

slightly indicated, near the margin. The characteristic postero-discoidal circumflex

mark of the elytra is sometimes absent, and the elytra wholly testaceous.

Closely allied to the preceding, but distinguished generally by the zigzag posterior

fascia of the elytra. The very different position of the lateral dilatation of the elytra

in the female is a still more definite specific character; this is situated far behind,

towards the apical curve, and is short and angular, with a smooth callus on the surface,

A large number of examples. In colour, and especially in the sculpture of the

pygidium, agrees with Burmeister’s description of C. testacea; but Burmeister places

C. testacea in his subsection “ body elongate cylindrical,” whereas our species is quite

remarkably short and rotundate-ovate. His description of the claw-joint of the

anterior male tarsi, “ missige verdickt,” is also inapplicable, as our species has the

claw-joint very unusually large and thickened, with the larger claw of extraordinary

length and stoutness. The closely allied C. minuta (found also on the Amazons) is a

smaller insect, 7 millim., and has a coarsely punctured shining pygidium. A Chontales

Distinguished by the elytra having together eight black spots arranged in a circle, of

which the two nearest the scutellum are the largest. The black spots on the thorax

are more variable in form and number, and in many examples disappear without

corresponding diminution of the elytral spots. The largest examples and those with the

largest black spots occur in Mexico. In specimens from Guatemala and further south

the spots are generally smaller and the general form of the insect more slender and paler

in colour, but large-spotted examples, though rarer, occur in Guatemala, as small-spotted

ones do in Mexico. The female is distinguished by the lateral margin being abruptly

produced into a small lobe a little behind the middle, the surface of the elytron

between the lobe and the slightly elevated callus being depressed. Found commonly

by Mr. Champion in the spathes of large Arums at Zapote. A specimen from Orizaba

is figured.

A large number of examples. Closely allied to the following, C. ampliata, notwith-

standing the different outline of the clypeus. Although coming within the definition

of Burmeister’s section “ Cyclocephale sinuate” the sinuation of the clypeus is

different from that of C. mafaffa and its allies, being a gradual incurvation from angle

CYCLOCEPHALA.—DYSCINETUS. 311

to angle with the angles well-marked, instead of being a curved sinus in the middle with

the angles rounded. The mandibles are remarkably small and much shorter than the

clypeus ; on dissection they are found to be closely applied to the roof of the mouth.

daire, Gen. Col. iii. p. 403 (partim) (nom. preoce., Thunberg, 1805).

Upwards of twenty species of this exclusively American genus have been recorded.

Although chiefly tropical a few are found in the warmer temperate zone both north

and south.

Some of the species greatly resemble certain forms of Hydrophilide, e. g, Hydrocharis.

Closely allied to D. dubius (Oliv.) of Cayenne, from which it differs in its narrower

oblong form and in the pygidium being throughout confluent-punctate in both sexes ;

the four coste on each elytron are also broader and flatter and the interspaces less

numerously punctured. In the broad apex and narrow reflexed margin of the clypeus

312 LAMELLICORNIA.

and the broadly rounded mandibles the species closely resembles D. dubius. The

closely sculptured pygidium led Burmeister to confuse it with the North-American

D. trachypygus; this latter is smaller and more ovate in form, more strongly pnnctate,

and has the pygidium still more densely sculptured and opaque and in the female

furnished with two polished callosities near the apex; in D. levipwnctatus the sculpture

of the pygidium is not so dense and leaves narrow smooth elevated interspaces.

The claw-joint of the anterior tarsi in the male is slender and straight as in the

female, with level under surface, and the larger claw is scarcely thickened and forked ;

in D. trachypygus it is much thickened and strongly sinuated underneath, with long

and thick much deflected larger claw. |

Two allied species (D). dubius and another undescribed) similarly differentiated in the

males are found together also on the Lower Amazons, and J at first thought they were

cases of dimorphism in the male; but the differences in the male claws are associated

with other differences in the form and sculpture of the pygidium. In D. levipunctatus

the pygidium is scarcely convex even in the male; in the following species it is rather

strongly convex in this sex and triangular, but has compressed sides in the female.

I have adopted the MS. name given to the species by Chevrolat in the Sallé col-

lection.

The strong and separated punctuation of the pygidium in both sexes mentioned by

Burmeister is very constant; but a more important specific character is the very robust

anterior tarsi of the male, the fourth joint of which is prolonged at the apex beneath

(the prolongation finely striated) and the claw-joint strongly sinuated on its under

surface, with the major claw remarkably broad, deflected, and unequally cleft, and the

slender division divergent. The clypeus is always undulate-strigose and much narrower

in front than in the preceding species, with its reflexed margin higher and sometimes

flexuous in the middle. The ligula differs from that of D. levipunctatus in being

deeply angulate-emarginate ; and the mandibles differ greatly in being sinuated externally

towards the apex, and not broadly rounded as in the typical species of the genus.

This new genus is necessary for the reception of the Heteronychus humilis of

Burmeister, a species which its describer afterwards excluded from Heteronychus on

account of the absence of stridulating-surface from the propygidium, and which also

differs from eteronychus by the simple claw-joints of the male anterior tarsi. The

under surface of the elytra near the margins is clothed with fine laid hairs. In the

bidentate clypeus Huetheola much resembles Dyscinetus bidentatus, from which it gene-

rically differs again in the simple fore tarsi of the male, and also in the shape of the

mandibles. The last-mentioned character separates it from Stenocrates, with which

genus it has the closest affinity, and to one species of which (S. holomelena) it bears

so striking a resemblance that if the mandibles formed the only point of difference

a generic separation would scarcely be justified; but Hwetheola has a further distin-

guishing character in the short basal joint of the hind tarsi, which effectively separates

it from Stenocrates, the latter having this joint always long and linear.

About a dozen distinct species of this genus have been described, all American, and

spread over the temperate as well as the tropical zones. The characters given by

Burmeister and Lacordaire require to be modified as regards the fore tarsi, which both

authors give as simple in both sexes, but which in about half the species have the

outer claw, in the male, thickened and deflected. The species are otherwise so closely

related, all agreeing in the singular position of the stridulating-surface, viz. underneath

the apical part of the elytra, and not, as in the Dynastide generally, on the propy-

gidium, that the genus cannot well be divided. ‘The mandibles are broad and

flattened, with their apical edge armed with two teeth, and their outer edge strongly

rounded, or in some cases forming a third tooth.

Ligyrus scarabeinus, Burm. loc. cit. p. 542 (nec Cyclocephala scarabeina, Perty).

Hab. Mexico, Teapa, Cosamaloapam (Sa//é).—Soutu America!, Guiana, Amazons.

Two examples (male and female), agreeing well with others from Demerara and

the Amazons with which I have compared them. Burmeister, as is clear from the

note following his description, confounded two widely-distinct species under his

L. scarabeinus. The “smaller-headed” form, with deeper thoracic excavation, to

which his unsatisfactory description chiefly applies, is that in which the anterior tarsi

are simple in both sexes; the “larger-headed” form, which appears to be equally

common in Guiana and the Amazons valley, has a strongly thickened anterior claw-joint

in the male, with the fourth joint produced and striated beneath. The latter is of a

deeper black colour, and more finely punctured; the clypeus shows a wider space

between the apical teeth; and the thoracic pit is narrower and triangular. ‘This is, no

doubt, the Scarabeus ebenus of De Geer (Mém. Ins. iv. p. 317, t. 19. f. 1), and according

to Kirsch (Berl. ent. Zeitschr. 1873, p. 346), for whom von Harold compared specimens

with the type at Munich, it is also the true Cyclocephala scarabeina of Perty.

LL. gyas, Eyichs. (Schomburgk, Reise Guian. iii. p. 561), is evidently closely allied to

L. latifovea; but the closely-punctured elytra and small shallow thoracic pit apply

better to a somewhat smaller species, of which I have many from the Amazons.

Ligyrus latifovea varies in size from 27 to 37 millim.; the clypeus is longer and more

narrowed anteriorly than in L. ebenus, and the apical teeth are much more nearly

approximated ; and the thorax has a higher and sharper frontal tubercle, and a much

broader (in large examples subquadrate) excavation. In both species the mandibles are

bidentate, and the tibie simply tridentate.

2. Ligyrus tumulosus.

Burmeister describes L. tumulosus as reddish-brown and strongly punctured (including

the pygidium), with broad bidentate clypeus and front transversely carinated (carina

depressed in the middle), and the thorax furnished with a feeble frontal tubercle and

slight depression. These characters apply to a species of which I find only two

examples in our collections, and which is very distinct from the deceptively-similar

L. sallei described below. ‘To Burmeister’s diagnosis must be added the important

narrow bidentate clypeus, like LZ. nasutus. |

The single example from Sturm’s collection agrees precisely with North-American

specimens of L. gibbosus (guwvencus) with which I have compared it. Numerous so-called

species have been founded on slight variations which are not more marked here than in

other species of the genus, and I follow Dr. Horn in re-uniting them. JL. gibdosus is

closely allied to L. tumulosus; but is generally shorter and relatively broader, with

the teeth of the clypeus approximated, the frontal carina median and entire, and the

tubercle and pit of the thorax more strongly developed. ‘The single specimen from

Durango city is much worn, but is evidently referable to the same species.

is entirely absent. The pygidium is smooth and polished, generally with a few

scattered punctures. A specimen from San Gerdénimo is figured.

In the male the anterior tarsi are short and thick, the fourth joint produced. beneath

into a longish flattened and striated tooth, and the outer claw is very broad and deflexed,

and deeply, but unequally, cleft at the apex. The size of the Amazons and West Indian

examples is 27-30 millim. M. Sallé’s single Mexican specimen is only 22 millim.

More than fifty examples, varying widely in size, form, and colour, but very constant

in the structural characters described above. The species comes very close to the

North-American ZL. relictus, having a very similar form of frontal carina, and similar

mandibles and anterior claw-joint and claws in the male. When a large series of each is

compared, much dissimilarity is shown as to general form and colour, and L. sallei

differs in every example in the much broader and less approximated clypeal teeth,

and the presence of a well-formed denticle between the 2nd and 3rd anterior tibial teeth.

Orizabus, Fairmaire, Rev. et Mag. Zool. 1878, p. 260; Horn, Trans. Am. Ent. Soc. xu. p. 124

(1885).

The genus Orizabus was suggested, without name, by Lacordaire, who, in a footnote

to his description of the Australian genus Chetroplatys, mentioned that he had a

Mexican species possessing characters belonging to. it, but differing in many essential

points; but these differences were not specified either by him or by Fairmaire, who

admitted the very close affinity between the Mexican and Australian forms. The

uncertainty under which the genus Cheiroplatys stands, owing to Hope’s erroneous and

misleading description and figures, and the further confusion he introduced by

founding his characters on an undescribed species, whilst citing as the type a Fabrician

species which has no near relationship to his described type, are no doubt partly the

cause why the genus Orizabus was founded and has been retained. I think, however,

the two genera may be safely reduced to one. The great similarity in the extraordinary

form of the fore tibie of the male in nearly all the species, and in the reflexed front

edge of the clypeus raised behind the true front edge, as well as the entire agreement

in form of thorax and legs and in the sculpture, is corroborated by a close agreement

in the parts of the mouth, especially in the short and broad, unarmed mandibles

(concealed in repose), and the elongated mentum, gradually narrowed but parallel-sided

in the ligular part, with the apex of the latter notched or truncated. Hope’s figure of

the maxillze is superficially accurate, but he failed to note that the two apparently

simple teeth are each two teeth side by side; as to the mentum his figure and

description are alike erroneous if they are taken from the same species, C. jwvencus of

Burmeister (Handb. der Ent. v. p. 110), which both authors consider to be the

(©. juvencus, Kirby, MS., the type of the genus. I have compared the parts of the

mouth of that species with those of C. (Orizabus) cultripes, Fairm.

Five species of Orizabus have been described from the United States and Mexico, and

twelve species of Cheiroplatys from Australia and the Islands of the Western Pacific.

Many of the latter require re-examination. .

This species is barely distinguished from the following by the immarginate base of

the thorax ; for some examples show a trace of marginal sulcus in the depression which

exists on each side, and it is often visible also towards the hind angles.

The anterior tibie of the female, both in this species and in C. clunalis, sometimes

assume the male form, 7. ¢. the outer side laminiform and unarmed. In all the other

Ihave compared type-specimens of the males of 0. marginatus and O. sall@i, bearing

The male, of which there are many examples, is readily distinguishable from the

‘same sex of the other species by the absence of thoracic fovea and marginal tubercle,

and by the tridentate anterior tibie; in all examples the thorax is free from traces

of marginal stria along the base, except near the angles. The female is not distin-

guishable, except in size, from the same sex of C. cultripes.

The numerous specimens may, perhaps, be only degraded forms of one or other of

the two larger species; some females (C. clwnalis) are of similar size, and are distin-

guishable from C. fairmairei only by the base of the thorax being margined. One

male specimen in the Salié collection is labelled, in Fairmaire’s handwriting, as

Orizabus sallei 2; but its small size shows that it was not included in his description

and dimensions of that species.

with the North-American form in both these respects.

Drury, apparently misled in some way by Fabricius, gave, in his Index (1773), the

inappropriate name of S. jamaicensis to the insect of which he figured the male and

female in the body of his work, stating, in the text, that he received the two, sexes,

found in copuld, from New York. Fabricius soon after (1775) described his two

species (S. satyrus and S. jamaicensis), the former the same as Drury’s species, the

latter evidently different from it, although he cites Drury’s figures. On these grounds.

Von Harold (Col. Hefte, vii. p. 117) proposed the suppression of the name 8. satyrus,

and the adoption of that of 8. jamaicensis for the New-York species. I cannot think

that such a ridiculous misapplication of the laws of priority will be adopted by ento-

mologists, especially by those of the United States, who, in fact, have hitherto ignored

Fourteen specimens. From Mexican examples of X. satyrus this species is not

distinguishable, except by the form of the thorax in the male, the fore part of which

is vertically truncated, with a central obtuse lobe projecting beyond the upper edge,

and the face of the truncation concave. A male specimen from Chiriqui is figured.

8. Xyloryctes telephus. (Tab. XIX. figg. 4, 4a, 5, 5a,¢.).

Xyloryctes telephus, Burm. Handb. der Ent. v. p. 209°.

Hab. Mexico1, Hacienda de Bleados in San Luis Potosi (Dr. Palmer), Oaxaca,

Chiapas (Sallé), Jalapa (Hége).

A large number of examples were collected by Herr Hoge at Jalapa, all agreeing in

the obliteration of the sutural stria (except near the apex) as well as in the smoothness

of the rest of the elytral surface, and in the long, nearly horizontal, conical lobe of the

thorax, which projects over the deeply concave and vertical anterior truncature. The

pygidium is much more sparsely punctured than in X. lobicollis and X. furcatus, and

is often smooth and polished in the female. In males of minor development the

thoracic lobe is very short and obtuse, but it is never absent. The size varies from

23 to 33 millimetres. The following is a doubtful variety, occurring in the same

localities as the type form :—

Var. X. ensifer, Sturm, MS. Thoracis lobus brevis, latus, obtusus, medio canaliculatus; elytra levia, stria

suturali punctulata subobsoleta. (Figg. 5, 5a.)

Hab. Muxico (Sturm, in coll. Sailé), Jalapa (Hége), Chiapas (Sailé).

We figure a typical well-developed male from Jalapa and a male of the var. ensifer

from Mexico (coll. Sturm).

4. Xyloryctes furcatus. (Tab. XIX. figg. 1, 1a, 2, 2a,¢.)

Xyloryctes furcatus, Burm. Handb. der Ent. v. p. 2097.

Hab. Mexico, Cordova (Sallé), Mexico city, Jalapa (Hége); GuatemaLa (Sallé),

Coban and Tactic in Vera Paz (Conradt).

Distinguished in the male (in well-developed individuals) by the narrow, long,

obliquely elevated and bifid thoracic lobe; and from X. telephus in both sexes by the

well-marked and punctulated sutural stria. The sides of the thorax in the male are

more strongly explanate-reflexed than in the same sex of X. telephus, but some

examples of the latter approach X. furcatus in this respect. The pygidium in the

male is more closely punctulated. We figure a well-developed male example from

Cordova, and a male minor from Jalapa.

5. Xyloryctes corniger.

Hab. Muxico (Sturm, in coll. Sallé); Panama, Volcan de Chiriqui 3000 feet

(Champion).

A single male example, labelled X. corniger, Sturm, resembles X. telephus, var. ensifer,

but has a well-impressed sutural stria and the thoracic lobe somewhat different, the

latter being much broader and not canaliculated. It is a weil-developed male

(32 millim. long), and has an almost perfectly straight cephalic horn flattened ante-

riorly. Two examples, males of minor development, from Chiriqui, agree with Sturm’s

specimen in thoracic structure, and have cephalic horns very broad at the base, but

small and acute-triangular in shape.

6. Xyloryctes teuthras. (Tab. XIX. figg. 3, 3a, ¢.)

3 minor. Breviter oblongus, castaneus, capitis cornu brevissimo basi lata apice acuto; thorace fere sicut in

passim punctulato punctis majoribus intermixtis.

Long. 24 millim.

Hab. Guatemata (Sallé), Aceytuno 5100 feet (Salvin).

Two examples only; of similar development to the two males of X. corniger from

XYLORYCTES.—MEGACERAS. 325

Chiriqui above described, but differing in the much more slanting truncature of the

fore part of the thorax and the absence of median prominence. Slight as their

peculiarities are they cannot be referred as varieties to any of the other described

species.

The species is labelled X. teuthras, Candéze, in the Sallé collection.

7. Xyloryctes thestalus. (Tab. XVIII. figg. 25, 25a, 3.)

Robustus, X. telepho latius oblongus, piceo- vel castaneo-niger ; elytris subtiliter punctulato-striatis, interstitiis

convexis, stria suturali punctata distincta sed medio parum impressa; pygidio disperse punctato.

& major. Cornu capitis altum, subrecurvum, apice postice nodosum ; thorax antice valde oblique declivis nec

medio concavus, lobo mediano longe post medium oblique ascendenti, apice lato et plerumque emarginato.

Long. 32-37 millim. <¢.

Hab. Mexico, near the city (Flohr, Hoge).

Numerous examples, differing but little in development, and all distinguished from

X. telephus, apart from the presence of a sutural stria, by the very different form of the

thoracic truncature, and the position of the central lobe or short horn projecting from

its upper margin; this latter in X. telephus and in other species rises much before the

middle of the thorax, and in X. thestalus considerably behind the middle, with the

correspondingly oblique truncature plane, instead of concave, in the centre.

Certain female examples from the same locality may belong to this species; they do

not, however, differ from the corresponding sex of XY. furcatus. They are of large size

(34 millim.), and have a distinct punctured sutural stria, with other strie on the elytra

indicated by convex interstices as in the male.

MEGACERAS.

Megaceras, Hope, Col. Man, i. p. 82, t. 1. fig. 1 (1837); Burmeister, Handb. der Ent. v. p. 221;

Lacordaire, Gen. Col. i. p. 435.

Seven species of this fine genus have been described, all from Tropical South America ;

one of them is here recorded for the first time as occurring north of the isthmus.

1. Megaceras philoctetes. (Tab. XIX. figg. 6, 6a, 3 var.)

Scarabeus philoctetes, Oliv. Ent. i. 3, p. 16, t. 14. fig. 125°.

Hab. Costa Rica (Saillé, Van Patten), Cache (Rogers); Panama, Bugaba, Volcan de

Chiriqui 4000 to 6000 feet (Champion).—Sovurn America, Surinam, Guiana, Brazil’.

The very numerous Central-American specimens differ from the many typical examples

from Surinam and the Amazons with which I have compared them sufficiently to be

distinguished as a local form :—

Var. M. septentrionis. Brevior, piceo-niger vel castaneus; clypeo acute bidentato; thorace brevi, lateribus

medio valde rotundatis, angulis posticis obtusis fere rotundatis, in g interdum (raro) subrectis.

g. Cornu capitis apice latum emarginatum, interdum subacutum, postice prope apicem obtusissime tuberculatum

vel simplex; thorace sicut in typo gibbere alto antice dentibus duobus subparallelis lateribusque a gibbere

usque ad angulos anticos et marginibus grosse strigosis.

2. Thorax dimidio anteriore et lateribus grosse, antice confluenter, punctatis, medio prope marginem anticum

obsolete bituberculatus.

Long. 32-45 millim. ¢ 92.

Examples of this variety are labelled in the Sallé collection M. morpheus, Burm. ; but

they do not at all agree with that author’s description, which refers to a species from

Colombia of narrow form, and especially narrow prothorax. Burmeister’s descriptions

of the species of this genus are, besides, so incomplete, that no safe determination is

possible.

The stridulating-strie of the propygidium are beautifully perfect on two divergent

ribs which cross the middle of the segment; on the rest of the surface they are coarser

and interrupted. In a highly-developed male example from Costa Rica the thorax is

longer than in the others, and is gradually narrowed in an incurved line from the

median dilatation to the anterior angles. J. philoctetes was found in the greatest

profusion in the water and along the banks of a lagoon in the dense forest on the slope

of the Volcan de Chiriqui at an elevation of 4000 feet (Champion). A well-developed

male from Bugaba is shown on our Plate.

Heterogomphus, Burmeister, Handb. der Ent. v. p. 225 (1847); Lacordaire, Gen. Col. ii. p. 437.

Twenty species of this ill-defined genus of Dynastidee are recorded, with two or three

exceptions all from South America, chiefly Brazil.

1. Heterogomphus chevrolati. (Tab. XIX. fige. 7, 7a,¢; 8, 84,2; 9,

Both mandibles and maxille in this species are toothless, and prolonged into narrow

sharp-pointed blades ; and the apical rims of the four posterior tibiz are minutely crenu-

lated, and not toothed. ‘The following variety is known only in the form of undeveloped

males, and though agreeing with H. chevrolati in mouth-structure and the form of the

terminal rims of the posterior tibiee, it may prove when further material arrives to be a

distinct species :— _

Var. H. ewrytus. g minor; brevior et latior, precipue elytris postice ampliatis. Rufo-castaneus, cornu

capitis brevissimum ; thorace valde transverso, lateribus arcuatis dimidio anteriore et lateribus fulvo-hirtis

grosse strigosis, foveseque late anterioris margine postico obtuse transversim tuberculato; elytris levibus,

DAMONOPLUS.

Demonoplus, Thomson, Archiv. Entom. 1. p. 68 (1858).

Heterogomphus, Gemminger & Harold, Cat. Col. iv. p. 1262 (1869).

This genus is limited, at present, to the following species, which Thomson, in

describing it, believed to be from the Gaboon. Gemminger and Harold included it in

the genus Heterogomphus; it has, however, well-marked peculiarities which render it

advisable to retain the genus formed for its reception. In the form and dentition of

its anterior tibiz in both sexes it comes much nearer to Podischnus, and the females

are not easy to be distinguished from the same sex of certain species of Golofa.

The anterior tibiee have four rather fine sharp teeth, and the terminal tooth is formed

like the others, and not broad and almost duplicated as Burmeister states of H. hopei.

The apical rim of the hindmost tibiz has four very short teeth, and that of the middle

tibiz one very long and sharp projection which is bidenticulate on one side. In these

points, and in the three slender, equal, and obliquely elevated thoracic horns of the

male, the species also differs from H. hope.

A male from Costa Rica and a female from the Volcan de Chiriqui are figured.

ENEMA.—STRATEGUS. 329

All gradations in the size of the tubercle on the hinder side of the horn of the male

are found when a large series is examined. Its absence is simply a sign of lower

sexual development. I do not remember to have seen the var. /upercus in the Amazons

region, where E. pan is rather common, and where it is twice the size of the largest

Mexican and Paraguayan examples that I have seen. Females of both forms do not

differ, except in their very much smaller size, from the same sex of E. infundibulum,

with which EZ. pan in the equatorial zone of America is always associated. ‘hese

curious facts of distribution and development of male horns according to latitude make

it extremely probable that E. infundibulum as well as E. pan and E. lupercus are only

varying forms of development of one and the same species, the development being of

size in both sexes, and of length and form of cephalic and thoracic horns in the male.

A male example from Cordova of the var. Jupercus is shown on our Plate.

8. Enema endymion, (Tab. XIX. figg. 13, 134, ¢ .)

A very distinct species, widely distributed, but apparently not common. It was

well described by Chevrolat in both sexes, but subsequently mistaken for £. /upercus

by Burmeister. The elytra are always rufo-castaneous, and the thorax unarmed in

both sexes, the latter being gibbous on the posterior disc, and minutely shagreened

(with some larger punctures) in the male, moderately convex, and more coarsely sculp-

tured in the female. . endymion is smaller and of a narrower oblong shape than

E. pan, and the thorax is more regularly arcuated on the sides, the curve continuing to

the anterior angles, which are acute, but not produced as in £. pan. The Venezuelan

E. paniscus, Burm., is a closely allied species, or local form, in which the thorax in the

male is smooth and highly polished in the middle.

We figure a male example from Tuxtepec.

This genus is exclusively American, and found in the temperate zones north and

south, as well as in the tropics and the West Indies. Seventeen species have been

described, three of which inhabit Central America*,

* The Munich Catalogue includes Mexico in the localities of S. antceus, but I have not seen a Mexican

specimen. Dr. Horn, in his paper on the North-American Strategi, gives Texas as the southern limit of the

The very numerous examples examined include the variations in the anterior thoracic

horn of the male (notched or simple), and in the smooth or rugose thoracic cavities,

mentioned by Burmeister, together with others not recorded by that author in the

general form and colour, and in the number of teeth on the apical rim of the posterior

tibie. Some examples are remarkably broad, and in consequence differ from the

majority in the greater width between the posterior horns of the thorax, and some are

wholly pitchy-black in colour. The dentition of the apex of the posterior tibize usually

consists of three teeth, the inner one much smaller than the others, and (apparently by

aberration) sometimes wanting or resolved into two smaller teeth. All examples of the

male agree in the more or less broadly triangular emargination of the front edge of

the clypeus; and this seems to be the sole character which distinguishes the species

from the South-American S. aloeus (Linn.), of which Linneus in his original description

(Mus. Lud. Ulr. p. 7) says, “Caput depressum, obtusissimum, angulis reflexis,” and

Burmeister, “deren vorderes Kopfende stumpf, beim mannchen mehr abgestutzt,

scharfkantig.” The female of S. julianus does not appear to differ from that of

S. aloeus, the clypeus being much narrower than in the male, and obtusely truncated

at the apex.

STRATEGUS.—PODISCHNUS. 331

I cannot corroborate Burmeister’s statement that the base of the anterior thoracic

horn is always continued behind as an obtuse ridge along the middle of the thoracic

cavity, dividing the latter into two deep pits; or that this is an important difference

between S. julianus and S. aloews. On the contrary, I have seen examples of S. juleanus

in both the larger and the minor developments of the male in which the ridge, except

just at the commencement, is scarcely perceptible.

We figure a fully-developed male example from Mexico city, and a male minor from

N. Yucatan. t

Mizigenus, Thomson, Arcana Nature, p. 7 (1859).

Two species only are known of this genus, restricted to Central America and the

northern part of South America.

Burmeister describes the singular comb-like dentition of the rounded maxillary lobe

quite correctly ; but at the apex of the mentum, which he says is broad, he has over-

looked the curious deflection of the true apical part of the ligula, which is triangular,

and bends downwards at right angles.

The male exhibits numerous gradations of form, affecting the shape of both the

cephalic horn and the curious thoracic elevation—half-moon shaped at the summit,

and clothed with tawny hairs beneath—and also the sculpture of the anterior part of

the thorax. ‘The principal gradations are as follows :—

1. Cephalic horn greatly elongated, and armed behind with a broad tooth.

2. The horn shorter, and the posterior dentiform thickening scarcely perceptible.

3. The horn only half as long again as the head, simple, acute ; thoracic horn only

slightly elevated, but broad, emarginated, and hairy beneath (S. darbicornis, Latr.).

4. The horn much shorter than the head; the thoracic elevation forming only a

slight prominence, with a hairy fovea in front of it.

0. The horn still shorter; the thoracic elevation advanced nearer to the front margin,

with a glabrous fovea in front.

Fairmaire has proposed (Rey. et Mag. Zool. 1878, p. 266) to reverse the decision of

Reiche, who referred Scarabeus barbicornis, Laty., to the prior S. agenor of Olivier,

and to regard it as synonymous with Podischnus tersander, Burm. In this I cannot

help disagreeing with him, as the description and figure of Latreille apply exactly to

the minor development described above (No. 3) of P. agenor, and do not at all agree

with the other species. Fafrmaire appears to have been misled chiefly by the simple

and flattened (from front and rear) cephalic horn of Latreille’s figure; but this is the

condition of the horn of P. agenor in minor developments, and the base is similarly

flattened even in fully-developed males. As to the general form of the body, the figure

of Latreille is that of an elongate-oblong insect like P. agenor, and not of a short and

posteriorly-dilated species like P. tersander. ‘The thoracic horn of the figure is also

totally unlike the form assumed by P. tersander in any of its developments.

We figure two males from Chontales, and a male minor and a female from Lion

Hill, Panama.

Fairmaire retains Thomson’s genus Mixigenus for this species, but does not specify

the points of structure in which it differs from Podischnus. ‘The two species, in fact,

agree unusually well in all characters on which genera are founded in Dynastide. The

structure and armature of the legs are strikingly homogeneous, especially the sharply-

toothed (instead of bristly) transverse ridges of the four hinder tibie.

We figure a male and a female from Orizaba.

This fine genus, one of the most remarkable forms of Dynastide found in the New

World, is widely distributed over the tropical zone of the American continent, and is

recorded, though possibly in error, as found in Chili. Fourteen species have been

described; but some of them are founded on varieties, the species being subject to

more than the usual range of modification as regards the shape of the horn-like

processes of the head and thorax, and the size and colour are equally variable.

The examination of a very large series of this species, mostly from Jalapa, shows

that it is extremely variable in the male sex, not only in colour and sculpture, but in

the length, form, and sculpture of the thoracic horn ; and, in fact, that no twa examples

fairly agree. The females, on the contrary, are, as nearly as possible, alike in form,

colour, and sculpture, and differ only in size. In fully-developed males, the apex of

the thoracic horn is always curved forward, and dilated into a broad and more or less

tridentate plate. Those examples in which the horn is very long form the G. sallei of

Thomson, and these vary in the horn being sometimes inclined backwards, in the

dilated apex, double the width in some examples that it is in others, obtusely carinated

above or marked with an impressed line, and in the length of the three teeth, the

anterior one being sometimes very much reduced, so that the front of the club is

nearly truncated, and sometimes short and notched. Males of all developments, in

which the thoracic horn is strongly punctured, form the G. clavicornis of Thomson ;

but the non-validity of this species is shown by the facts that all the males of low

development, with short subcylindrical thoracic horn, have the horn coarsely punctured,

and that the coarsely-punctured horn does not correspond with coarsely-punctured

elytra (as Thomson avers); moreover, every sradation is present, in a large series, with

regard to the punctuation of the horn; and all were found together by Herr Hoge in

the same locality.

The general colour of the male varies from testaceous-yellow, through castaneous to

sooty-black, the thorax in the yellower examples being generally more or less clouded

with brown, and very rarely wholly brown. The underside of the body and legs also

vary from yellowish or reddish-testaceous (with all articulations and tarsi darker) to

sooty-black. The head entirely and thoracic horn are always black. The suture and the

extreme lateral margin of the elytra in the yellower examples are dusky. The females

are wholly black, moderately shining, and coarsely subconfluently punctured, and are

difficult to be distinguished from the similarly-coloured females of allied species. The

entire upper edge of the mandibles (in which they agree with the males) is the chief

differentiating character; the colour of the pubescence on the under surface is tawny

cinereous, scarcely rufescent as Burmeister gives it, and quite different from the foxy-

red hue which distinguishes the very similar female of G. championt.

G. hastatus (Castelnau), referred to this species by Burmeister, seems to me to belong

to G. imperialis. The form of the thoracic horn described is that of the undeveloped

male; but the size (17 lines) and the length of the cephalic horn are not those of this

class of male in G. pizarro, though agreeing well with G. imperialis.

We figure a fully-developed typical male from Tuxtla, and four others of the same

sex of the var. clavicornis, from ‘Toxpam, Cordova, and Jalapa, showing the different

developments of the cephalic and thoracic horns, and also the variation in the sculpture

of the upper surface.

Hab. Mexico}? (Sturm, in coll. Sailé), Capulalpam, Cuernavaca, Duraznal (Sa//é) ;

Evidently very closely allied to G. pizarro, but probably specifically distinct. It is

larger, and the largest examples of the male (46 millim.), which, judging from the

long cephalic horn, are of full development, have a thoracic horn with parallel sides

bent forward and pointed at the apex, and therefore different in shape from either the

major or the minor males of G. pizarro ; in the male minor the thoracic horn is reduced

to a thick and very obtuse tubercle. The surface is more finely punctured, and the

suture and lateral margins of the elytra are blacker, the thorax in some examples spotted

with black, and the humeral angles of the elytra and the scutellum also black. ‘The

female is entirely black. In both sexes the apical edge of the mandibles is sometimes

faintly (in the female more sharply) notched towards the inner angle, a character which

distinguishes the species from G. pelagon and G. wgeon, in which the mandibles are

bifid.

Hope’s description of the male of his G. incas, especially with regard to the thoracic

horn, “thorax cornu erecto, brevi, apice acuto,” scarcely applies to G. imperialis, and

that of the female is still less applicable. I have seen no Golofa, 2 , from Mexico of the

colour he describes ; but the present species is named G. incas in the Sallé collection.

We figure a well-developed male from Mexico (cold. Sturm), and a male minor from

Duraznal and another from Guatemala.

Although in structure this species comes nearer to G. imperialis, it bears a greater

general resemblance to the Venezuelan and Peruvian G. egeon; from the latter it differs

in its more cinnamon-tawny hue and less distinct black suture and margins, and in the

form of the thoracic horn in the different developments of the male, the horn in G. egeon

being strongly compressed laterally in all stages, except the somewhat dilated apex of the

most highly-developed individuals. The basal joint of the anterior tarsi is short (not

longer than the second) in G. e@geon; the hind tarsi robust and densely hairy beneath,

and the mandibles narrow and bifid. A well-developed male is shown on our Plate.

male, from Mexico, described and figured by Thomson measured 44 millim., although,

judging from the rudimentary state of the tubercle on the posterior side of the cephalic

horn, it is not of the highest development of the sex; examples of similar development

from Chiriqui are only 34 millim., and others of higher stage, in which the tubercle on

the cephalic horn is distinct, acute, and situated nearer the middle of the horn, and in

which the thoracic horn is of relatively much greater length than in Thomson’s speci-

men, measure only 40 millim. All the examples, nevertheless, agree in other respects

with the figure above cited.

The species is distinguished from the three described from South America by the

long, slender, pointed thoracic horn, which projects subhorizontally beyond the apex of

the porrected cephalic horn.

The males, as they decrease in development, lose all trace of posterior tubercle on

the cephalic horn, and in the lowest stage both that and the thoracic horn are

extremely short (about 2 millim.), both still preserving the shape and direction charac-

teristic of the species.

exceptions, as the upper tooth is sometimes scarcely perceptible, or disappears alto-

the absence of the broad pit behind the thoracic tubercle, whilst the P. affinis described

The following is the only known species of this genus, distinguished from Phileurus

chiefly by the tridentate mandibles. In this feature it agrees with Zrioplus, to which

genus it is very closely allied, differing chiefly by the simple fore-tarsal claws in the

male and the entire apex of the clypeus.

The specimen described by Prof. Westwood has only two teeth on the right mandible,

but as the two other examples (¢ ? ) have both mandibles tridentate, it appears probable

that the bidentate state in this case is an aberration. The female (recognizable, as usual

in the Dynastide, by the entire apical margin of the apical ventral segment) is precisely

similar to the male, except that the cephalic horns are very much shorter, and the

declivous anterior surface of the thorax is only half as large. I suspect, however, that

the difference is not always so great, as the females in Zrioplus are almost exactly

similar to the well-developed males, whilst minor males have much shorter cephalic

horns.

in which the dark purple velvety elytra are unicolorous, with the exception of four

rather small yellow marginal spots in the situation of the lateral terminations of the

fascie and apical spot of the typical form. Mr. Janson in describing the male calls

attention to the extraordinary form of the mentum, the disc of which is produced as a

stout vertical spine, remarking, justly, that no trace of this exists in the male of

A. anomala, and only a slight indication of it in the male of A. lansberget.

The species with emarginated clypeus and long spiniform teeth at the apex of the

four hind tibiz (genera Amithao and Desicasta) being withdrawn, this genus is here

left as defined by Burmeister. It includes about twenty species distributed throughout

the tropical and north temperate zones of America, and distinguished by having the

same armature of the head in both sexes, namely an erect clypeal horn often much

reduced, until in the aberrant forms it consists of a barely perceptible median elevation

of the reflexed apex of the clypeus, and a horizontal frontal horn, which likewise is

sometimes partly atrophied, but in the most aberrant species is visible as a tolerably

distinct central carina. The genus Latemnis of Thomson I consider as certainly

congeneric with Cotinis, but Balsameda is rather better defined, consisting of those

species in which the external posterior angles of the hindmost coxe are obtuse and not

acutely produced as in the rest of the genus; the armature of the head remains,

however, normal, and I think it advisable to retain it as a section of Cotinis.

2. Cotinis mutabilis. (Tab. XXI. fig. 5; Tab. XXII. figg. 4, 4a, 5, 5a,

12, 12 a, vars.)

After careful examination of about 250 examples I have come to the conclusion that

the characters adduced by Burmeister to distinguish this species from C. sobrina are in

the highest degree inconstant, and that there are no means of defining the two species.

All that can be said is that C. mutadilis is, in the great majority of its individuals, larger

and broader. The shape of the clypeal horn is very variable, and its varieties do not

correspond with variations in size, breadth, and colour, large and robust specimens of

the typical mutabilis having the horn either dilated towards the apex, parallel-sided, or

triangular, and the same diversities may be seen in small and slender oblong examples

of C. sobrina. It is the same with regard to form and colour; for it is far from the

case that the large and broad examples (C. mutadilis) only are unicolorous; smaller

and narrower individuals exist equally unicolorous and of nearly all the colour-varieties

displayed by the larger set. It is true that the variegated varieties described by

Burmeister under C. sobrina are, as a rule, smaller than the others; but they are

connected by the most finely graduated series of variations, so that it is impossible to

draw a distinction between the two. series. ‘The case is a very difficult one to deal with.

It would not be satisfactory, and scarcely practicable, to include under one specific

diagnosis all the numerous varieties, some of which are possibly local, thus presenting

an interesting study to future collectors and students; the better course seems to be to

treat the more distinct separately, giving the localities of each :—

The shining punctured striz are visible chiefly in the depressed intervals between

the suture and the first costa and between the two coste; they are in each interval

two in number, and the space between the first pair is irregularly punctured ; the apex

between the callus and the suture is also more or less punctured. ‘The males are

slenderly oblong, like the smallest males of C. mutabilis; the females are more robust

and subquadrate. The species was captured in abundance by Herr Hoge at Almolonga ;

it is in many points intermediate between C. mutabilis and C. pauperula.

The single female example from Granada, Nicaragua, differs from all the others in

its larger size (28 millim.), and broader, more robust figure. It resembles, in fact,

closely, certain Guatemalan examples of C. mutabzlis, typical form, which have a broadly

triangular clypeal horn, except in the numerous shining green punctures of the

elytra.

striate elytra, but the punctures are opaque ; and it also differs in the frontal horn being

reduced to a sharp carina, never free, though nearly always vertically truncated at the

extremity. The clypeal horn is always very short and triangular, and the sternal

process somewhat narrow and rather more acutely rounded at the apex than in C. mutabilis.

The margins of the thorax are distinctly less broadly incrassated than in C. mutabilis

and C. punctato-striata; in this respect the species approaches the North-American

C. nitida. The colour varies: (1) dullish green, very dark and tinged with brassy

beneath ; (2) the same, with the margins of the thorax and the whole of the elytra,

except a broad triangular juxtascutellar patch, dull fulvous; (3) wholly fulvous above,

Burmeister mistook a (probably slender) female example for the male, and described

both sexes as having sharply tridentate anterior tibie and the scattered scaly clothing

as changing into scaly hairs on the under surface and legs. But the true males, in fact,

have remarkably slender fore tibie, with no conspicuous tooth except the long curved

terminal one; the second tooth is only slightly indicated, and in some examples entirely

wanting, and the uppermost tooth is a very short sharp spine. The males have scattered

oval scales over the entire body and legs; in the females the scales change on the

pygidium, under surface, and legs into more or less slender hairs. In length the species

varies from 17 to 21 millim., and in width from 74 to 12 millim. (@. gracilis, Sharp,

is founded on a slender male example.

Burmeister says the males are lighter in colour and the females darker with the

apex of the elytra only pale; but this distinction is not constant, as most of the males

I have seen have the same characteristic fulvous apex (clouded with pale brown) as the

females; the darkest or blackish individuals are, however, females. The mesosternal

epimera are not furnished with a shining apical tubercle, and the mesosternal process

is simple, 2. e. without tubercle above, and of little vertical thickness; characters which

distinguish the species from several others of similar colour and markings.

An example obtained from the late Edwin Brown’s collection, and ticketed “ Brazil,”

agrees with Burmeister’s description of this species, and I suspect the locality attached

is erroneous, the real habitat being most likely Colombia. A Chiriqui specimen from

Ribbe agrees with it, except that the black spots of the elytra unite in larger patches.

The ground-colour of this (the typical form) is above dark greyish or tawny-brown,

with two or three distinct orange-coloured spots on the margin of the elytra. The

species is extremely close to G. chontalensis. Besides the very different colour and the

fewer and larger black spots of the elytra, I find no differences except that in G. coturnix

the thorax has more acute and produced hind angles, and the black tubercle of the

epimera is surrounded by a pink ring. The sternal process is a little less abruptly

bent downwards, but the degree of this may be a variable character; it has the same

great vertical width as in G. chontalensis. The male is of a uniform dark grey colour

beneath as in G. chontalensis.

GYMNETIS. 307

The examination of a large series has shown that G. ramulosa is only a slight and

inconstant variety of G. chevrolati; but I have seen no specimen agreeing in the yellow

lines of the elytra with Gory and Percheron’s figure except one from Mr. Edwin

Brown’s collection labelled “Panama.” In all the others the yellow fascia very nearly

reaches the suture and in some both the fascia and borders are of considerable width, a

small dark spot remaining at the junction of the fascia and border on each side. The

colour of the upperside varies from dark olivaceous-brown to rich purplish-black. In

the original description! of G. ramulosa the symbols of the sexes were accidentally

reversed ; it is the male that has the under surface dark (blackish) grey, and the

female the glossy-black abdomen and middle of the sternum.

Our five examples (three males, two females) agree with V. de Poll’s description, if

we may understand his terms “cervina” and “fallow” to mean bluish-grey, for this

is the colour of the underside, the mesosternal epimera, and the vague spots and

borders of the numerous black spots and streaks which on a ground of ochreous make

_up the beautiful and highly diversified colour-pattern of the upperside. The males

have more bluish-grey above, and the yellow spots of the female are more orange-

coloured.

Allorhina, Chevrolat, Ann. Soc. Ent. Belg. xiv. p. 6.

Distinguished from Gymnetis, with which it agrees in the velvety-opaque upper

surface of the body, by the clypeus being narrowed to the front and triangularly (not

very deeply) emarginated at the apex, the spinose-dentate apices of the four hinder

tibiee, and (in the typical species) by the acuminate sternal process curved upwards at

the apex. The abdomen in the males is depressed and longitudinally subsulcate in

the middle.

The following two species only, both peculiar to Central America, are known. The

second differs from G. hwet in the sternal process being shorter, acutely conical, and not

recurved at the apex.

2. Guatemalica marginicollis.

Gymnetis marginicollis, Burm. Handb. der Ent. iti. p. 266°.

Hab. Muxico ! (Sallé), Almolonga in Vera Cruz (Hodge).

Named G. marginicollis, Burm., in the Sallé collection, and agreeing with Bur-

meister’s description, with the very important exception of the emarginated clypeus,

Burmeister saying expressly “ kopfschild vorn aufgebogen, nicht ausgebuchtet.” It

is only on the venturesome supposition that Burmeister’s specimen had the head of

another species ‘fixed to it that I adopt M. Sallé’s determination ; one of Herr Hége’s

two examples has also a false head glued to it, apparently the head of a Huphoria.

The chalky-white or yellow markings of the elytra are sometimes separated mostly

into spots, viz. (in a female example) one in the middle of the base on each elytron,

two on the disc nearly side by side behind the middle, a short marginal streak near

the shoulder, another on each side of the scutellum, and a flexuous fascia near the apex

extending from the suture to the outer angle. In two male examples the spots (all in

the same position) are united in streaks, the scutellar stripe with the basal spot, and

the two spots on the disc in an angular band reaching the lateral margin, the subapical

fascia remaining the same. In the male the mesothoracic epimera are entirely opaque

white, and the naked part of the underside is faintly punctured. Burmeister describes

his insect as a male, shining (7. e. glabrous) and rugose beneath, with the hind margins

of the ventral segments at the sides grey: this agrees precisely with our female

specimen.

: AMITHAO.

Amithao, Thomson, Typi Cetonid. p. 11 (1878).

Cotinis (pars), Burmeister, Handb. der Ent. iii. p. 263.

Melasictes, Thomson, Le Naturaliste, i. p. 268 (1880).

This genus seems to be sufficiently well-defined by its deep and angularly emargi-

nated clypeus, the three more or less spiniform apical teeth of the four hinder tibie,

and the horizontal sternal process, generally conical but sometimes more elongate and

flattened. The type-species of Thomson (A. laferte?) has, at least in the male, what he

terms a tubercle on the head, “¢ caput tuberculatum;” this no doubt refers to a

prominence which marks the abrupt end of what in Cotinis would be a frontal carina

or horn, but which in Amzthao is scarcely elevated. This structure is more pronounced

in another species, A. cavifrons; but in others it disappears, leaving as a trace of its

termination a small pit near the base of the raised edge of the clypeus. There are

gradations in this structure from species to species, which are not accompanied by any

360 LAMELLICORNIA,

other character of importance. I therefore do not venture to adopt Thomson’s genus

Melasictes, the chief justification of which lies in this character, although the descrip-

tion does not point it out.

The genus seems to be peculiar to Central America and the northern parts of South

America.

Moscheuma, Thomson, Le Naturaliste, i. p. 268 (1880).

Stethodesma (pars).

After defining the genus somewhat imperfectly in 1878, Thomson redescribed it

more intelligibly in 1880, re-naming it and giving the same species as belonging to it.

The only character which distinguishes it from Amithao is the obliquely deflected and

thick sternal process, described by Thomson as “ mesosterni appendix robustissima sat

elongata, paullo subtus directa, apice rotundato.” D. lobata (Oliv.), a well-known species

from Guiana, is included both in Desicasta and Moscheuma by the author, also

D, sculptilis, Thoms. (the type of Desicasta), the description of which offers nothing to

distinguish it from D. lobata and D. reichei, Thoms. Under Desicasta is further enume-

rated D. hematopus of Schaum, which does not agree with the others in the form of

the sternal process.

The genus appears to be confined to Colombia (with Panama) and Guiana. JD. lobata

(Oliv.) and D. sebosa (Van de Poll) are also found on the Lower Amazons.

Euphoria (pars), Horn, Proc. Am. Phil. Soc. 1879, p. 398.

A North-American genus, of which three species have been described. The following

differs from the generic type in the clypeus having only two spiniform teeth at the

apex instead of four; but in the rounded thorax (entire near the scutellum), the short

narrow mesosternal process, and the strongly elevated exterior ridges of the four hinder

tibie, in the middle pair bicuspid, the species accords with Stephanucha. Although

the clypeus has only two teeth at the tip, there is a trace of another on each side in the

distinct angle formed on the abrupt narrowing of the clypeus towards the apex.

Erirhipis, Burmeister, loc. cit. p. 385.

Euryomia (pars), Lacordaire, Gen. Col. ii. p. 527.

A genus difficult to define, though the same may be said of many other genera of

Cetoniide which have hitherto been generally admitted. It comprises nearly all the

‘“‘ Cétonides vraies” of Lacordaire found in America, all of medium or small size, and

differing greatly in colours and style of markings and in the shape of the clypeus and

other structural features on which systematists rely for generic characters in this

difficult family. The clypeus especially presents in different species the various forms

characteristic of many distinct genera of the Old World, such as Cetonia, Euryomia,

Elaphinis, and others; and this was chiefly, no doubt, the cause of Lacordaire’s too

EUPHORIA. 363

hasty conclusion that Euphoria was admitted only on considerations of geographical

distribution, and that it should be merged together with numerous Old-World genera

under Euryomia. Dr. Horn, rightly, considered that the author of the ‘Genera’ in

this proceeded too far. On the examination of a large series of species and individuals

it is found that the clypeus in this group is exceedingly variable: first, to a minor but

still considerable extent among individuals of the same species, and, next, in various

degrees from one closely allied species to another; the variability of this important

member may in fact be adduced as one of the characters of the genus, the variations

being modifications of a certain typical form, 7. e. narrowed anteriorly with the apical

margin more or less reflexed and sinuated. The most constant structural feature is

that of the mesosternal process, which is always horizontal and more or less dilated

and rounded at its apex.

About 45 species have been described, the great majority from the United States

and Mexico.

A large series of examples. M. Sallé took £. latreillei and E. lesueuri in copula, and

convinced himself that the former (velvety-opaque above and generally smaller) is the

male of E. lesueuri, distinguished by its glabrous and shining thorax, more spotted

elytra, and generally larger size. The external characters of the male, one or other of

which is commonly preserit in the Cetoniide, fail entirely in this species, the pygidium

only showing a slightly greater convexity in some examples; but on dissection, examples

of EH. lesweurt are found to be males. The species varies in colour from green to dark

purple and olivaceous-black, and the size from 16 to 22 millim.

guishing this species. But they also agree in the gibbous convexity of the pygidium,

which Burmeister does not mention, but which Gory and Percheron specify as a

characteristic of their E. latreillei. The three examples are all green. The differences

in colour and in the frontal carina, as well as in other numerous points enlarged on by

Burmeister, are not of the slightest value, as they exist in all gradations in EZ. lesweuri.

Many male examples of the latter species show traces of pubescence on the sides of the

thorax. I doubt very much if the E. westermanni of Burmeister is the same as Gory

and Percheron’s species of the same name, as it does not agree either with their

description or their figure, especially with regard to the spinose sutural apices! of the

elytra; it is possible that this character may be variable, but none of our specimens

show any distinct trace of it.

brassy-green, coppery, and tawny-red with coppery-red gloss; also in the form of the

clypeus, which assumes such a diversity of outline in individuals otherwise so nearly

alike that no other proof is necessary of the unreliability of this part for classificatory

purposes in the group of Cetoniide to which this genus belongs—it is most frequently

rather elongate, curvilinearly or rectilinearly narrowed, with reflexed sub-bidentate

apex; from this it rapidly varies to trapezoidal and to semiovate with or without

strongly raised margins and entire apical border, and to short and transverse with high

and entire margins. The variety rufina will be seen, from the localities enumerated

above, to have a more northerly or elevated range than the type-form, and it is often

much more densely pubescent above, but insensible gradations connect the two forms.

A good series of examples. The prevailing colour is, as the author describes it, dark

greenish-blue, but it varies, and a rufous variety (like that of £. lewcographa) is not

uncommon. ‘The species scarcely differs from LH. leucographa, except in the sparser

punctuation and impunctate dorsal vitta of the thorax, and in the generally shorter

clypeus, which latter varies in the sinuation of the apex, but less so than in L. leuco-

grapha. The transverse chalky spots on the sides of the ventral segments exist only in

a few examples of the male, and the metasternum has sometimes on each side, visible

under the long grey pubescence, a few large scale-like whitish spots.

Closely allied to E. iridescens, Schaum. One of our examples agrees with Janson’s

description with regard to the elytra being of a dark olive-green ground-colour (like

the rest of the body), with some small obscure yellowish spots on the elytra; but in

others there is as much dark yellow spotty-colouring on the elytra as dark green, and

the sides of the elytra especially are yellow with a series of large, quadrate, but

irregular, dark green spots. The thorax is dark green, with a fine dorsal line and a

small basal spot on each side yellow; but in one example the thorax has four dark-

green vitte as in HL. iridescens.

Thomson’s description is taken from an unusually small specimen (124 millim.); the

numerous series before me (which includes examples named by Sallé) range from

14 to 18 millim., the smallest being males, brassy-black, with the elytra thickly

sprinkled with confluent transverse and undulated fulvous spots. The females much

resemble H. precaria, and the species connects Section IV. with the present group, to

which it belongs by the clypeus being in the male narrowly quadrate, with the apical

margin strongly reflexed, and more or less deeply sinuated, sometimes almost bidentate,

in the female shorter and less reflexed. The upper surface in fresh specimens, especially

in the male, is rather densely erect pubescent, the thorax and scutellum shining, and

the elytra opaque. The more or less thickly punctured and large scutellum is an excellent

distinguishing character. The antennal club is elongated in both sexes, in the male

about one fourth longer than joints 1-7 taken together. The thorax, as usual in this

eroup, differs in form in the two sexes, but not in all examples—in the male being

gradually narrowed (with a slight sinuation) from the base to the apex, in the female

strongly rounded about the middle. The female varies much in colour—the head,

thorax, and scutellum being more or less rufous, with a strong metallic gloss, and

sometimes metallic green vitte, and the elytra fulvous, with numerous small transverse

confluent spots, or, in extreme cases, almost spotless.

Differs from E. mystica in its much smaller size and opaque thorax and scutellum, the

latter being smooth, with the exception of a puncture or two near the base. In most

respects it is much more nearly allied to £. vestita, from which it differs in the

clypeus being narrower, much longer, and more reflexed-sub-bidentate at the apex.

E. avita is of rather smaller and more slender form, and offers a somewhat different

range of variation ; some examples being dull dark green, a triangular spot on the basal

lobe of the thorax and a few transverse undulating spots on the elytra only being

fulvous, in which state it resembles a small H. submacu/osa. ‘The clypeus in both

sexes is as described under E. mystica. In the great majority of examples the elytra

are fulvous, with very numerous blackish spots, the thorax blackish with a dorsal

line, and a discal spot on each side, and the base fulvous, and in many the lateral and

anterior margins are also of the same colour. The antennal club in the male is rather

longer than joints 1-7 taken together. The anterior tibiee are tridentate in both sexes,

the upper tooth sometimes very short in the male.

anterior tibiz in the male. The shorter, broader, and squarer clypeus distinguishes it

from E. avita. The markings of the thorax are the same as in the clear-coloured

examples of both the other allied species. ‘There is scarcely any difference in colour

Burmeister describes this species as having, in the male, an excessively large antennal

club and nearly simple anterior tibie. A few male examples answering to this

description, with females corresponding in size and colour, have been received from

the above-mentioned localities. The figures cited from Gory and Percheron represent

females, and are indeterminable, but in general form and markings they agree with

this species. . vestita is larger (15 millim.) than any of the preceding species, and

more convex and elongate-ovate in the males, this sex having the antennal club twice

the length of the remaining joints, and correspondingly broad. The thorax is trape-

zoidal, but rather elongated, and is strongly arcuate-sinuate in the middle of the base.

Closely allied to E. atra, but larger, more oblong, and always glabrous above and

beneath, generally black; the antennal club in the male is scarcely longer than joints

1-7; the scutellum is shining, and more or less punctured, the punctuation generally

confined to the base; the elytral coste are narrower and more strongly elevated ;

and the grey pubescence of the under surface is dense on the sides of the ventral

segments. Some examples have traces of reddish spots at the base (sometimes at the

sides) of the thorax and on the elytra, or are reddish-tawny, with two broad dusky vitte

on the thorax and the elytra marbled with dusky; these specimens are not easily to

be distinguished from abraded examples of £. vestita, the sinuation of the basal lobe

of the thorax is, however, considerably less.

Hab. Mzxtco!2, Ventanas in Durango (Hége, Forrer), Vera Cruz (Sallé), Tonila in

Colima, Colima city, Tapachula in Chiapas (Hoge); Guatemata, Tactic (Conradt).

The unicolorous black variety described by Burmeister is distinguishable from

E. atra by the two chalky-white spots of the pygidium, and the much narrower and

elongate form. A beautiful variety was captured by Hoge at Colima city, black, with

the thorax broadly margined with rich red. The typical form was found by Hoge in

great profusion at Tapachula, on the lower part of the Pacific slope.

The form of the clypeus differs from that of the species included in Section VI. in

the apical margin being greatly elevated, and deeply emarginated in the middle. The

male anterior tibie are long and slender, often with only one (terminal) tooth, and

when bidentate the upper tooth is obtuse, and separated from the apical one by a deep

sinuation. This structure is quite different from that of E. vestita and HL. exwmia of

Section VI.

Allied to 4. subtomentosa. The clypeus is short and broad, but not quite so broad

or rectangular as in that species. The elytral cost (especially the outer ones) are not

nearly so elevated, and the ochreous spots are not arranged in three longitudinal rows,

but are in extremely irregular and variable transverse macular streaks; the apex is

broadly ochreous, with a denuded spot in the centre, and there are some transverse

streaks on the lateral margins almost as in LH. lineoligera. In fact HE. histrionica seems

to connect the last-named with . swhbtomentosa. ‘The antennal club in the male is as

long as joints 1—7, but still not notably elongated, as the whole antenna is short.

euish Genuchinus from Psilocnemis. Both agree in the rounded outline of the thorax,

and apparently in the flattened form of the mentum.

Three species were described by Westwood from Ecuador and Mexico.

the described species number twenty-three.

By the form of the clypeus this genus is nearest allied to Cremastochilus, but the

disc of the mentum is not in the slightest degree cupuliform, and more nearly resembles

that of Genuchinus, and the form of the thorax is unlike that of any American genus

of the group.

Burmeister placed this extraordinary and isolated form, in which the head and

thorax are cornuted, in the family Dynastide, notwithstanding its semimembranous

mandibles; but Candéze having had an opportunity of examining both sexes, and

finding that the clypeus of the female was that of a Cetonid, and the anterior femora

exserted, has shown that it belongs to the melitophilous series of Lamellicornia, and

that it would be best placed by the side of Jnca, in the Trichiide. The species on

which the genus is founded is of extreme rarity.

This species is distinguished by its narrow oblong form, the great length of the sides

of the thorax after the antemedian dilatation, and the broad quadrate black circum-

scutellar (including the scutellum) spot of the elytra, on the hinder margin of which a

short, sometimes interrupted, fascia crosses the suture. The raised triangular plate of

the thorax and adjoining parts are impunctate.

This species is distinguished from its allies by the absence of white spots near the

suture or on the scutellum, and the simple coloration of the elytra, without trace of the

usual black lines and curves. There isa faint trace of the usual short lateral trans-

verse white lineola on the elytra. The thorax in both examples is possibly abraded,

and the yellow pubescence in the triangle-shaped sulci consequently wanting.

The markings of the elytra, well described by Burmeister, are tolerably constant, the

most characteristic being a black line arising from a broad spot behind the shoulder,

which curves towards the narrow sutural vitta (with which it is connected by a short

transverse line), and continuing thence down the disc nearly parallel to the suture ends

in a large apical spot. The general form is shorter than in the allied species, ovate rather

than oblong. The thorax is correspondingly shorter, more angularly dilated in the

middle, and with the sides more or less sinuated to the hind angles, which are rectangular

or acute; the yellow triangular signature of the disc is short, and the grooves in which

it lies are strongly impressed, but not quite so strongly and broadly as in 7. archimedes

and 7. simplex, and in the S. Brazilian 7. triangulum. ‘The sexes closely agree, and I

do not find that the female is differently coloured to the male or smaller than it, as stated

by Burmeister, who must have had before him a variety in describing the female. The

typical state varies slightly in its elytral markings, the short transverse lineole being

sometimes absent, and in other cases the longitudinal curved line interrupted; the

following recede further from the type-form :—

Var. 7. nigrinus. Niger, opacus, elytris utrinque versus humeros macula rotunda aurantiaca. Thorax angustior,

A large series of this insect was obtained by Herr Hoge at Almolonga, offering

scarcely any variation, and giving the impression of a species very distinct from the

series of J’. geometricus from Cordova, which is also found at Almolonga. The

differences between the two forms are, however, to a great extent bridged over by the

var. intermedius described above, and slighter individual variations. The Tehuantepec

examples bear the MS. name of 7. elongatulus in the Sallé collection. The following

variety is somewhat more distinct :—

COALOCRATUS.

Celocratus, Burmeister, in Germar’s Zeitschr. iii. p. 242 (1841); Handb. der Ent. in. p. 767.

One species only has hitherto been described of this genus, from “the interior of

Northern Brazil.” I refer the following, smaller, Mexican species to the genus

owing to the very similar form of the clypeus (in which Ce/locratus differs from all

other genera of Trichiide), viz. transverse-quadrate, with straight front edge and equally

raised fore and lateral margins. The Mexican insect also agrees in the form of the

thorax and elytra, and in the anterior tibie having two outstanding teeth in both sexes,

but it differs in the middle tibize of the male not being bowed.

1. Celocratus znescens. (Tab. XXIII. fig. 13.)

Oblongo-ovatus, parum convexus, toto erecte (apud caput et thoracem multo longius) pubescens, viridi-wneus vel

obscure eeneus, nitidus ; elytris opacis, testaceo-rufis vel fulvis, sutura et marginibus, vitta utrinque angusta

recta, antice abbreviata, dorsali, vittaque latiore curvata et intus bilobata laterali, obscure viridi-eneis,

interdum yagis et subobsoletis; thorace fere sicut in Trichio fasciato rotundato, angulis posticis vix

SUPPLEMENT.

‘Tur following supplementary pages contain descriptions of the new species received

during the progress of the present volume, together with indications of new localities

for species previously recorded and a few rectifications of synonymy, errors, and omis-

sions that have been detected since the foregoing parts were published.

PSEUDOLUCANUS (p. 1; to precede the genus Cantharolethrus).

Pseudolucanus (Hope), Parry, Trans. Ent. Soc. Lond. 1870, p. 72.

According to Major Parry this genus includes four described species, viz. one North-

American, one peculiar to the Mediterranean region, one Indian, and the following

from Northern Mexico :—

1. Pseudolucanus mazama.

Hab. Mexico}, Santa Clara in Chihuahua (Hoge).

I am indebted to Mr. Flohr for calling my attention to this species, which was over-

looked in the former part of this work. It has since been captured in large numbers

by Herr Hoge.

ZESALUS (p. 2).

2 (a). Aisalus smithi.

Zi, neotropicalt valde affinis et similis; differt statura paullo majore coloreque subsenescenti-fusco et preecipue

cantho oculari multo breviore et latiore; supra nitidior, sparsius et discretius umbilicato-punctulatus,

setulis griseo-fuscis (haud nigro-fuscis) brevioribus et sparsioribus, elytrisque interstitiis planis.

Long. 5 millim.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith). One example only.

The much shorter and broader canthus of the eyes is the principal character which

distinguishes this species from . neotropicalis, the length of the canthus being scarcely

one fourth the width of the eye and its ridge arcuated, whilst in #7. neotropicalis it is

about one half the length of the eye and linear, with a straight ridge. Compared with

a good series of . neotropicalis the surface is conspicuously more shining, due to the

more separated punctures and correspondingly sparser sete, which latter are also

shorter and lighter in colour.

Long. 37 millim.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith). Two examples.

In the punctate-sulcate elytra this species resembles P. brevis (Truqui), and in the

glabrous sides of the elytra and thorax P. championi, Bates; but it differs from both

in the more elongate and dorsally-flattened elytra and in the longer “ horn” of the

vertex, which is porrect and compressed, and also in the abbreviated frontal carine,

from the ends of which the tubercle is removed to the anterior angles of the

forehead.

SORANUS (p. 19).

9. Soranus depressifrons.

S. recticorni similis, sed elytris relative longioribus. Sat anguste elongatus, politus; labrum antice paullo

angustatum, sinuato-truncatum, grosse punctatum ; clypeus latus, levis, margine subrecto; frons toto

pressa, punctato-sulcata ; prothorax subtus tibieque dense fulvo-hirsuta.

Long. 25 millim.

Hab. Mexico, Huitzilac in Morelos (Hoge). ‘Two examples.

_ The leaflets of the antennal club are short (not more than twice as long as the joints),

but the species does not well fit into any of the genera of the restricted group ‘ Passa-

lini’? which have this character. ‘The prominence of the anterior margin of the thorax

in the middle, limited on each side by the end of the deep and broad marginal sulcus,

is a character of the genus Veturius; it is, however, only slight in the present case, and

LAMELLICORNIA. 389

the small head, strongly-punctured elytra, and facies show a closer relationship to Soranus

than to Veturius, in which the head is remarkably broad, and the elytra finely

punctulate-striate.

PASSALUS (p. 21).

Passalus striatopunctatus (p. 22).

CANTHON (p. 26).

Canthon speciosus (p. 27). :

To the localities given, add :_-Mextco, Teapa in Tabasco (H. H. Smith).

Dr. Horn (Trans. Am. Ent. Soc. 1870, p. 45) gives this name as synonymous with

C. cyanellus, Lec., from Texas. ‘The two species are, in fact, almost identical in form

and in the deeply emarginate clypeus, bispinose in the emargination, and differ only

in the punctuation of the upper surface, which in the Texan species is very distinct

though fine, imparting to the elytra a slight opacity, whilst in all Mexican examples

it is scarcely perceptible with a strong lens, and the whole surface is highly polished.

Canthon euryscelis (p. 28).

To the localities given, add:—Muextico, Atoyac in Vera Cruz, Teapa (H. H. Smith),

Temax in North Yucatan (Gaumer).

Canthon viridis (p. 30).

To the localities given, add :—Mexico, Rincon in Guerrero (H. H. Smith), Temax

in North Yucatan (Gaumer).

Many specimens have lately been received from Yucatan, nearly all of the dark

violet form, a few only having the thorax tinged with green.

Canthon gagatinus (p. 33).

M. Sallé has pointed out to me that this species, or its blue variety C. amethystinus,

Harold, is the Ateuchus humectus of Say, a name omitted by Harold and Gemminger

in the Munich Catalogue, and also by Harold in his monograph of the genus Canthon.

Dr. Horn also informs me that C. indigaceus of Leconte belongs to the same species.

The synonymy therefore will stand thus :—

I give these localities, which add nothing of importance to the range previously

recorded, simply to note that all the very numerous examples from Capetillo are of the

violet-black form, all from Guerrero bright green, and all from Temax blackish-green,

especially on the elytra.

PSEUDOCANTHON (p. 35).

2. Pseudocanthon chlorizans.

Canthon chlorizans, antea, p. 34.

To the Mexican locality given, add :—Temax in North Yucatan (Gawmer).

A large series has been received from the above-named locality, and on further

studying the species I find that it has all the characters of the genus Pseudocanthon

—the longer mesosternum separated from the metasternum by a sharp straight suture,

the flexuous inner edge of the fore tibie, and the sides of the thorax parallel from the

base to near the anterior angles, and thence sharply narrowed to the apex. IJ am

inclined now, however, to doubt the generic importance of the longer and sharply

delimited mesosternum, as this character is somewhat variable in the genus Canthon,

C. transversalis, Har., and C. balteatus, Boh., belonging to distinct sections of the genus,

having the same form of this segment as Pseudocanthon.

P. chlorizans is of a glossy, but not deep black colour, often with a slight greenish

tinge, but without pale markings ; the legs are always testaceous-red ; the elytra, espe-

cially behind, are studded with minute shining hair-scales, as in P. perplerus. The

prothoracic cavity beneath near the anterior angles is deep and sharply margined.

Phanezus scutifer (p. 60). (Tab. XXIV. figg. 1, 1a, 2.)

Mr. Flohr has sent me the female of this species from Oaxaca, which is remarkable

for the distinct although short horn in the middle of the vertex :—

2. Lete viridi-metallicus, capite fere toto, thorace processu antico callisque posticis necnon signaturis disci

Hab. GUATEMALA, Tepan (Conradt).

The bronzed examples of this species much resemble P. beltianus, but the surface

is less shining and the opaque sulci of the elytra are much broader. In the form

of the thorax it comes nearer P. palliatus, the hind angles of the flattened triangular

disc being as in that species more elevated, and the keel which extends from the sharp

apex of the angle towards the lateral fovea is flexuous.

Phanzus pilatei (p. 65).

Hab. Mexico, Omilteme in Guerrero 8000 feet (7. H. Smith).

My. Smith obtained two well-developed males and one male minor, with several females

of this form, which may prove to be distinct from O. chevrolatt. In the latter the

middle anterior protuberance of the thorax is broad and rather concave im front; in

the var. omiltemius it is narrower, and forms a simple tuberiform prominence.

There is a distinct tubercle on the crown asin QO. chevrolati; the surface is opaque,

bronzed-black, with fine and sparse punctuation on the thorax. ‘The females are of

the same colour, but the surface is silky and undulating; and they are distinguishable

from the same sex of the following (O. undulans) only by their colour.

Hab. Mexico, Omilteme in Guerrero 8000 feet (7. H. Smith).

The two examples appear to be females, and all the claws are simple. A. omiltemius

resembles the species of the 4. mexicanus group in so many features that it ought

probably to be placed in it. It lacks, however, what von Harold considered

LAMELLICORNIA. 5/3.

an essential character, viz. the produced and acute gene. But the character is not

always strongly pronounced, and is very slight, for instance, in A. villosipes.

I refer the single example from Teapa to H. castanea with some reserve, Serville’s

species being known to me only by description. Our insect agrees, however, in form,

punctuation, and colour with the careful description of Dr. Horn above cited. In the

Southern States, according to Dr. Horn, EL. castanea is found in the nests of a small ant.

Four examples agreeing well with the detailed description above cited, excepting

that I am unable to detect the “ spinula accessoria”’ near the apical spurs of the hind

tibie, which is probably a variable character and perceptible only in well-preserved

individuals. The outer apical angles of the same tibie are prolonged and acute. The

sculpture of the elytra is similar to that of A. complicatus, from which the present

species is readily distinguished by its smaller size (4 millim.) and by the short but sharp

tooth on each side of the emargination of the clypeus. ‘The carine of the elytra, eight

in number on each side, are narrow from the base to the apex, each being accompanied

by a less elevated and more or less crenulated line on each side, and the punctures of

the broad strie are large and strung closely together.

Two examples resembling in form and sculpture the Panama specimens which I

referred (anted p. 101) to A. carinator, Har. They are larger (34 millim.) and therefore

accord better with Harold’s description.

OCHODZEUS (p. 105).

Ochodzus luridus (p. 106).

The example from the Sallé collection referred to this species is probably distinct.

Mr. H. H. Smith obtained at Omilteme in Guerrero four specimens of an insect which

agrees much more closely with Westwood’s description ; these all have the short frontal

carina between the eyes, this carina being more or less depressed in the middle and

nearly separated into two transverse tubercles. ‘The sculpture also agrees with the

description. The peculiar form of the left mandible described and figured by

Westwood, viz. bidentate at the apex and not sharply pointed as in both mandibles of

all other species of Ochodeus, is certainly not shown in our examples; but I think it

is clear that this is a mutilation, the figure on being regarded attentively evidently

representing a mandible in which the tip is broken off. The anterior tibie are

unarmed at the inner apex in all the specimens.

The two species will therefore stand thus :—

400 SUPPLEMENT.

PHYTALUS (p. 174).

In the characters of Section I. b, at p. 177, with regard to the lower spur of the hind

tibiee being connate, the words ‘‘in the male” were inadvertently omitted. The same

omission occurs under Lachnosterna at p. 196.

Phytalus (?) pubicollis (p. 176).

To the locality given, add:—GvatemMaLa, Coban in Vera Paz (Conradt).

The species is rather small (15 millim.) and slender, oblong, tawny-castaneous and

shining, though clothed throughout somewhat densely with short suberect ashy pile.

The elytra are closely and finely punctured, with undulating wrinkles, and without coste

or strize, the head and thorax being more distantly, and the pygidium more coarsely and

sparsely punctulated, the latter with coarser ruge. In the male the tarsal claws have

the teeth rather close together, though the lower tooth is much broader and more curvate-

deflexed, a character which induced me to query the position of the species in the

genus Phytalus. The female taken by Conradt differs from the male in the dentition

of the claws, the lower tooth being nearly as narrow and sharp as the apical one, and

more bent and apparently situated lower down the claw. This form of dentition is

entirely foreign to the Phytalus group, and the species should be removed to Lachno-

sterna. The pygidium in the female is scarcely convex and slightly prolonged, flattened

and smooth at the apex.

Phytalus bolacoides (p. 182).

To the Mexican locality given, add:—Omilteme in Guerrero 8000 feet (4. H. Smith).

Mr. H. H. Smith obtained on his recent journey several examples of both sexes of

this curious little species. In none of them is the triangular circumscutellar spot so

dark and conspicuous as in the unique type specimen (@ ), being at most indicated by a

slightly browner tint in that part of the otherwise tawny-yellow elytra, neither are the

elytra in the female so widely dilated behind. In some, apparently immature, examples

the head and thorax are testaceous-red, in others they are brownish-black as described.

The similarity in form and coloration—chestnut-brown, with broad lateral (marginal)

thoracic vitta testaceous-yellow—and, especially, the very similar sexual characters in the

pygidium and abdomen, render it doubtful if this is a distinct species from P. fisstlabris.

But the difference in the volume and convexity of the eyes, and the flatter, broader, and

less sharply sinuated clypeus being constant in the large series of specimens taken at

Omilteme, and confirmed by the much closer and finer sculpture, I consider it necessary

to treat them as a separate specific form.

We have two examples of this elegant and distinct species, both males. In the

dentition of the claws it agrees rather better with the species of Section V. than with

those of Section II.; but it seems preferable to leave it at the end of the latter section

in the vicinity of the two polyphyllous species there located.

Lachnosterna rorulenta (p. 196).

To the localities given, add:—Mexico, La Venta in Guerrero, Teapa in Tabasco

(H. H. Smith).

Lachnosterna parvisetis (p. 196).

Among the numerous examples of Z. rorulenta taken by Mr. H. H. Smith are some

in which many of the elytral punctures have a short seta. As the occurrence of these

setee (not the long loose hairs with which the elytra are provided towards the apex,

and which are often seen also in'Z. rorulenta) furnishes the sole character of the present

species, it must be withdrawn and treated as a slight variety of L. rorulenta. The

pygidium in the female is impressed and bituberculated at the apex as in L. rorulenta ;

in the following very closely-allied species the form of the pygidium is very different.

Fight examples. The sexual difference in the dentition of the claws is greater than

in any other species of Lachnosterna I have examined, the lower tooth being very curved

and situated above the middle in the female, whilst it is short and straight, and placed

nearer the base than the middle, in the male. The species is also remarkable in

Section IV. for its elongate, slender form.

The two unnamed Anomale, Nos. 45 and 104, from Playa Vicente, are possibly

females of this species; but their mutilated condition, especially the absence of anterior

and intermediate tarsi, renders their determination doubtful. They are more oblong

in form and somewhat smaller than the four examples above described.

Anomala nitidula (p. 246).

Hab. Guatemaia, Chimaltenango (Conradt).

It will be seen that the modification relates chiefly to the sculpture, the only colour-

difference being that the tarsi in the variety are pale in both sexes and black (at least

in all the examples before me) in the Mexican A. vidua: an analogous difference in the

form and colour of the sexes is presented by both type form and variety.

Pelidnota punctulata (p. 276).

According to Mr. Flohr, the locality “Jalapa” given by Herr Hoge is a mistake, as

the species does not occur there. It is an inhabitant of the “ tierra caliente.” He has

received it from Minatitlan, Atoyac, and Playa Vicente. A dark brassy-brown, nearly

black, variety has been received from Conradt taken at Escuintla, Guatemala.

Plusiotis laniventris (p. 283).

Mr. Flohr states that this species is confined in its range to the “tierra fria.” He

finds it near the city of Mexico and also at the Hacienda de las Trojes, on the border

of the States of Mexico and Michoacan. It feeds on the leaves of the oak and alder.

Plusiotis adelaida (p. 283).

To the localities given, add :—Muxico, Omilteme in Guerrero 8000 feet (7. H.

This species also, according to Mr. Flohr, does not occur outside of the “ tierra fria ”

in Mexico. Hége’s localities Jalapa and Oaxaca are wrong; his specimens were obtained

near Mexico city, Atlapango, and Parada. Mr. Flohr adds as localities, Quecholac, Xolo-

loya, on the slopes of the Cofre de Perote. It feeds on the young shoots of pine-trees.

Plusiotis rodriguezi (p. 283). (Tab. XXIV. fig. 21, var.)

One of Mr. Smith’s specimens is a clayey-reddish-tawny variety similar to the corre-

sponding variety of P. costata mentioned at p. 282. It differs from that, however, in

the sides of the elytra and the under surface having a rich metallic tinge, thus corre-

sponding with the green typical form.

Hab. Mexico, Suapam, Volcan de Orizaba (Sal/é).

M. Sallé is of opinion that this species does not belong to Plusiotis; but I can see no

difference except in the shorter and more semicircular clypeus, which it has in common

with P. lecontei and P. alticola. ‘The base of the labrum is broad and sinuated as it is

in Plusiotis and the Rutelide generally.

The unique example is in a damaged condition and I am not sure that the outline of

the thorax has not been distorted. The colour of the dense and long villosity of the

breast is the character which chiefly inclines me to think the species is distinct from

P. leconteét.

A pair of this species has been sent me by Mr. Flohr, who points out its close

affinity with C. amena. It differs from C. am@na in the sparser punctuation of the

upper surface, in which character it is intermediate between C. ama@na and the more

strongly punctured examples of C. macropus. It agrees with C. amena in the pro-

minent, though small, mesosternal process, which is narrower and more acute, though

much stouter than in C. erubescens.

I have named it, at Mr. Flohr’s request, after the discoverer, Mr. Richard Becker of

Durango, who is exploring with great success the Coleopterous treasures of the

interesting region near which he resides.

A SUPPLEMENT.

When fresh this fine species is of a beautiful bluish-green colour, which is soon lost

after death. The Misantla specimens were cut out of tree-trunks by Mr. Flohr.

HETEROSTERNUS (p. 287).

Heterosternus buprestoides (p. 288).

The type specimen of this rare species, Mr. Flohr informs me, on the authority of

M. Blanchard, was taken near Zongolica; a second example, he says, has been taken

on an Aguacatillo tree between Huatusco and Mirador; and a third, now in the

Philadelphia Museum, was obtained from Sumichrast, but in what locality it was

found is not known.

Parisolea fulva, antead p. 288, Tab. XVII. fig. 1.

The locality of this species is Jalapa, where it was cut out of old or felled Liquid-

ambar trunks (fo/r).

P. fulva was founded on examples found in the manner above-mentioned, but curiously

discoloured by being kept in a damp locality; it must therefore be withdrawn.

METAPACHYLUS (to precede the genus Aspidolea, p. 296).

Gen. Pachylo affinis, sed valde differt mandibulis longe exsertis recurvis acuminatis: Gen. Rutelisce quoque

The interesting form on which this genus is founded partakes of the characters of

Pachylus, Oryctomorphus, and Parastasia, with the allied Indian forms Dzdrephano-

phorus, Peperonota, &c., genera widely separated in the received classification. It has

much also in common with the genus Rutelisca, which would be better placed in its

vicinity than in the group Rutelina, the tarsal claws not being really unequal in length,

their different curvature only making them appear so. ‘he North-American genus

Polymechus apparently belongs to the same hitherto unindicated group of genera.

Hab. GuateMaLa, Tepan (Conradt).

Three examples, viz., two males, one female; the female with imperfect hind tarsi,

the claws of which are inferred to be toothed like the others.

ANCOGNATHA (p. 297).

Ancognatha quadripunctata (p. 298).

To the localities given, add :—GuatTEMALA (Conradt).

CYCLOCEPHALA (p. 299).

Cyclocephala complanata (p. 301).

A single example, taken by Conradt at Coban in Vera Paz, is much larger than any

of the other Mexican or Guatemalan examples I have seen, measuring 21 millim., the

others ranging from 16 to 17 millim.

CHEIROPLATYS (p. 320).

Cheiroplatys isodonoides (p. 322).

To the Mexican localities given, add :—Amula in Guerrero 6000 feet (H. H. Smith).

GOLOFA (p. 332).

Golofa imperialis (p. 334).

To the localities given, add:—Mexico, Amula 6000 feet, Soledad 5500 feet, and

Xucumanatlan 7000 feet, in Guerrero (H. H. Smith).

A good series has been supplied by Mr. Smith, including one large example 50 millim.

long, which is probably of the fullest development, and tends to establish the validity

of the species. Its thoracic horn is only 10 millim. long (measured from the surface

of the thorax behind it), but the apex is but very little dilated and angulated laterally

and at the tip. In the largest males of G. pizarro, measuring 42 millim., the thoracic

horn is fully 15 millim. long and very broadly dilated and tridentate at the apex.

The elytral humeri are more often concolorous than black. The four female examples,

all black, show a constant difference from G. pizarro, female, in the nearly smooth

apical half of the pygidium and less rugosely punctured elytra.

414 SUPPLEMENT.

GOPSIS (p. 337).

#igopsis curvicornis (p. 337).

Aigopsis westwood, Thoms. Mus. Scient. p. 17, t. 6. fig. 2°.

M. Sallé informs me that the only other described species of this genus, 4. west-

woodu, Thoms., is not from the interior of Brazil as Thomson stated ! but from Panama.

This is confirmed by the fact that the slight differential features mentioned by Thomson

are seen in at least one of our Panama examples.

ISCHNOSCELIS (p. 343).

Ischnoscelis dohrni (p. 343).

My. Flohr informs me that an example of this rare species has been taken at Tonila.

COTINIS (p. 346).

Cotinis mutabilis (p. 346).

Var. 2. C. mearcana (p. 346).

To the Mexican localities given, add :—Omilteme 8000 feet, Amula 6000 feet, Venta

de Zopilote 2800 feet, and Xucumanatlan 7000 feet, all in Guerrero (H. H. Smith).

All these examples have a pointed clypeal horn.

Var. 8. C. atrata (p. 347).

Add to the Mexican localities:—Amula 6000 feet, and Venta de Zopilote 2800 feet,

in Guerrero (ZZ. H. Smith).

13 (a). Cotinis salicis. (Tab. XXIV. fig. 25.)

C’. antonii affinis et simillima, sed valde differt thoracis lobo obtuso sat late truncato. Nigra, polita, pubescentia

subtus nigra; caput quadratum, fronte late concava, punctata et nigro-setosa, carina centrali vix elevata

et obtusa usque ad clypeum continuata ibique gradatim subsidente; clypeo lato, margine antico valde

reflexo recto; thorace elytrisque, precipue lateribus, sparsim punctatis. Pygidium strigulosum, plagis

duabus cretaceis. Processus mesosternalis quam in C. antonii paullo longior, apice rotundato. 6.

Long. 20 millim.

Hab. Mwxico, near the city (flohr).

In decayed willow-trees (lohr).

13 (z). Cotinis rufipennis.

? (no. 18), antea p. 353.

O. antonii affinis. Oblongo-quadrata, nigra, velutino-opaca, subtus (et capite) glabra polita, pectore pedibusque

nigro-hirsutis, elytris (sutura angusta nigra excepta) miniato-rufis ; clypeus sicut in C. antonw margine

antico recto oblique reflexo, fronte quadrata, concava, sparsim punctata carinaque alta acuta longe ante

elypei apicem subabrupte terminata; antenne nigre; thorax trapezoideus, sparse punctatus, disco levi,

ante medium paullo dilatatus, lobo basali mediocre, obtuse rotundato seutelloque conspicuo acute triangu-

Cotinis

LAMELLICORNIA. 415

lari; elytris absque sculptura opacissimis. Pygidium nitidum, glabrum, subtiliter sparse strigosum. Pro-

cessus mesosternalis quadratus haud porrectus, antice truncatus. '

3. Tibize anticee extus inermes, dente apicali obsoleto. Thorax apud marginem anticum medio paullo pro-

ductus culminatus. Venter late coucavus. Pygidium convexum, utrinque prope apicem late foveatum.

Q? Tibiz antice extus dente unico brevi, dente terminali recte prolongato.

Long. 16-20 millim.

Hab. Mexico, Canelas in the Sierra Madre de Durango (Becker), Santa Clara in

Chihuahua (/ége).

The example brought home by Herr Hoge is much crushed, and I am not sure that

it is a female, though it is broader and larger than the undoubted male specimen

received from Mr. Flohr.

GYMNETIS (p. 353).

13 (4). Gymnetis vandepolli.

Gymnetis kerremansi, antea p. 357, cum Tab. XXI. figg. 7, 8 (nec Van de Poll).

M. Van de Poll having sent me a drawing of G. kerremans?, I perceive that his is a

species quite distinct from that which I described and figured from Chontales and

Bugaba under this name, and which I now nameas above. G. kerremansi will remain,

therefore, with the locality “‘ Panama ” only.

Obs. G. wollastoni, Schaum, Trans. Ent. Soc. Lond. v. (1) p. 66, t. 8. f. 3, described

as from Mexico, is a Venezuelan insect.

EUPHORIA (p. 362).

1 (4). Kuphoria monticola.

taceis; clypeus quam in &. lesueurt paullo longior, lateribus paullo rotundatis, antice angustatus et sub-

bidentatus cum fronte concavus, grosse punctatus, medio vertice obtuse carinato ; thorax sat grosse discrete,

disco subtilius et dispersius, punctatus, lateribus subrugosis, lobo basali subrecte truncato ; scutellum lave ;

elytra utrinque valide bicostata, sparsim punctulata apicemque versus rugulosa, interstitio prope suturam

postice plaga nigro-velutina; pygidium confluenter subtiliter rugulosum, nitidum, sparse incumbente

pilosum. Subtus olivaceo-nigra, polita, cum pedibus tenuiter griseo-pilosa. ‘Tibiee anticee tridentate.

Long. 18 millim. °.

Hab. Mexico, Canelas in the Sierra Madre de Durango ( Becker).

A very distinct species allied to #. lesweurt and E. candezev.

Euphoria lineoligera (p. 366).

To the Mexican localities given, add:—Rincon 2800 feet, Mescala, and Venta de

Zopilote 2800 feet, all in Guerrero (H. H. Smith).

Euphoria biguttata (p. 366).

To the localities given, add:—Maexico, Tepetlapa 3000 feet, and Acaguizotla 3500

feet in Guerrero (H. H. Smith).

4.16 SUPPLEMENT.

Euphoria dimidiata (p. 367).

To the localities in Mexico, add:—Mescala, Chilpancingo 4600 feet, Rincon 2800

feet, Venta de Peregrino, Acaguizotla 3500 feet, all in Guerrero (H. H. Smith).

Euphoria pulchella (p. 367).

M. Sallé believes that there are two species mixed up in the varieties attributed by

authors to L. pulchella, one in which the elytra are plane and another in which they

are prominently bicostate. ‘The two species would stand thus :—

13. Euphoria pulchella,

Elytra utrinque bicostata.

Cetonia pulchella, C. ferrugata, and C. montesuma, Gory & Perch.

13 (a). Euphoria childreni.

Elytra disco plana. .

Cetonia children and C. thelasco, Gory & Perch.

The colour-varieties in the two species, though similar, do not eee correspond ;

but according to our series of specimens the two forms occur together in many

localities.

Euphoria subtomentosa (p. 373).

To the Mexican localities given, add :—Chilpancingo 4600 feet in Guerrero (H. H.

Smith).
