INTRODUCTION.

Part 1 of this Volume contains Canon Fowler’s enumeration of four families of

Homoptera—the Membracide, Cercopide, Tettigoniide, and Gyponide. The material

of the Jasside was entrusted several years ago to a well-known Homopterist, who

volunteered to prepare an account of them for this work. Unfortunately, nothing

has been finished by him, nor have the specimens been returned to us, in spite of

repeated applications to that effect. We are therefore compelled to close Volume II.

as it stands, the concluding portion of Canon Fowler’s contribution having been

received in 1903. Twenty-five species of Membracide and four of Cercopide have

since been added by other authors to the Central-American fauna, the Membracide

mainly by the late G. B. Buckton, either in his ‘Monograph’ (1903) or in a paper

published in the ‘ Transactions of the Linnean Society’ [Zoology, (2) ix. pp. 329-338,

pls. 21 & 22 (1905) ], and a list of them is appended on pp. 318-322, with some notes

by Canon Fowler. For the four families, exclusive of those mentioned in the

Supplement, 659 species are enumerated, of which 385 are treated as new, with 42

new genera. Of the twenty-one coloured Plates issued in Volume II., which were all

drawn and printed by Mr. KE. Wilson, of Cambridge, ten are devoted to the extra-

ordinary insects belonging to the family Membracide.

Part 2 of this Volume includes the enumeration of the families Aleurodide and

Coccide by Professor T, D. A. Cockerell, This section of the subject is separately

paged and indexed, and it is illustrated by figures in the text.

Membracides, Germar, Mag. der Ent. iv. p. 7 (1821).

Membracide, Curtis, Brit. Ent. xii, Gen. p. 14 (1840).

Jassida (ex parte), Stal, Hem. Afr. iv. p. 82 (1866).

The members of this family are chiefly distinguished by the great development of

the pronotum, which in many cases completely covers the whole body and occasionally

the tegmina as well, and in most of the genera is much enlarged and conceals the

scutellum. In the Centrotine, however, the extension of the pronotum does not

conceal the scutellum, which is left more or less exposed, and in some genera the

posterior process is diminished to a mere elongated point, while in a few the posterior

process is entirely wanting ; these may, as a rule, be known by having the metopidium f, |

or front part of the pronotum, strongly and more or less perpendicularly declivous ; in

the genus ithalion, however, there is no posterior process of the pronotum, nor is the

metopidium strongly declivous, but the position of this genus is very doubtful.

Stal regards his ‘“ Membracida” as merely a subfamily of the Jasside, yet, in spite

of this, he classes Ai¢halion and other doubtful genera among the Centrotide; in

any case, however, the wisdom of this arrangement appears to be doubtful, for the

Membracide, as a whole, form one of the most distinct and unmistakable groups of

all insects.

* By W. W. Fow.zr.

+ I have used this term throughout to express the declivous part of the pronotum reaching from the base

of the head to the front of the dorsum.

2 HEMIPTERA-HOMOPTERA.

The headquarters of the family appear to be in Central and Tropical South America;

a considerable number, however, are found in the Southern and Central parts of the

United States of North America. | oe |

In his “Synopsis of the Subfamilies and “Genera of the Membracide of North

America” (Trans. Amer. Ent. Soc. xix. pp. 253-260), Dr. Goding enumerates sixty-

five genera, of which the great majority also occur in Central America; a certain

proportion also occur in Africa, Tropical Asia, and Australia; Staél (Hem. Afr. iv.

pp. 82 et seg.) enumerates eleven genera and twenty-five species from Africa, and twenty-

three genera as from Africa, Asia, and Australia combined ; only three genera and

five species are recorded as European, two or three of which appear to be somewhat

doubtful.

The Membracide contain some of the most extraordinary forms that are found

among the Insecta. The characters of the genera, however, are sometimes obscure, as

they lead very closely one into the other, and it is hard to draw the line anywhere,

although the extremes (as e.g. Membracis and Bolbonota) appear to be quite unlike

in every way until examined with the whole series; the venation of the tegmina affords

good characters, but is not of equal importance in all the groups, and occasionally

breaks down. It is probable that good characters may eventually be found in the

male organs in certain genera; but, except in one or two cases, I have found them of

very little practical value as yet, and this will be the case until more material for

dissection is provided.

I am much indebted to Mons. Severin, Herr Handlirsch and Dr. Ganglbauer, and

Dr. Aurivillius, for their kindness in sending me typical specimens for examination

from the Brussels, Vienna, and Stockholm Museums respectively ; and also to Dr. Goding

for his kindness in comparing many genera and species with those in his extensive

collections and for giving me his opinion regarding them. ;

The Membracide may be divided, for convenience’ sake, into the subfamilies mentioned

below ; they might, perhaps, more correctly be divided into two subfamilies only, the

Membracine and the Centrotine, but as the present state of our knowledge of the

Homoptera generally is very incomplete, it does not much matter which arrangement

we adopt. In the Centrotinz certain genera have the posterior process of the thorax

wanting, but in these the metopidium is more or less strongly declivous, except in the

ease of Athalion: the position of this genus, however, is open to much doubt, but I

have, with much hesitation, allowed it to remain with the Membracide; it must at

any rate be granted that its affinities are in several points strongly towards the family,

and that certain of its species have the metopidium much more declivous than others;

it must always, however, be regarded as holding an exceptional position.

I have not adopted the arrangement of the subfamilies followed by Stal and some

other authors, as it seems preferable to begin the group with the Membracine rather

than with the Tragopine as they have done; as a matter of fact, the question is one of

small importance at present, as the affinities of the groups are as yet but imperfectly

understood.

This genus originally contained a large number of species which have been referred

to other genera ; it is now very well-defined, containing only the large and conspicuous

insects with the pronotum. strongly raised and foliaceous, and more or less rounded,

sometimes semicircular ; they appear to be confined to Tropical America. The larve

of the genus are very curious, being of much the same shape as the perfect insect, but

formed of separate upright narrow plates of different heights,

This species appears to be by far the most abundant of the genus in Central America.

It is very variable in size and also in colour; the specimens from Chilpancingo are of

a bright sulphur-yellow, whereas the majority are more or less orange, and small light

yellow, almost greyish specimens occur; the black markings are also variable. ‘The

larger specimens attain a length of 9 or even 10 millim., whereas the smaller -do not

exceed 6 millim. In Signoret’s collection the larger specimens, which we regard as

M. mewicana, are placed under M. stolida, whereas the small light specimens are

referred to M. mexicana; from the large series in our collection it is, however,

evident that they belong to the same species. UM. sexmaculata is only a small light

variety of the type form; Walker’s type is from Honduras, and exactly agrees with two

specimens from Nicaragua in our collection. We figure a typical example from Chil-

pancingo, and one of the var. sermaculata from Teapa.

There is a specimen in the Vienna Museum collection which appears to be a variety

of this species, labelled “ Mexico, Puebla (Bilimek),” and I have found another in the

collection of the Royal Belgian Museum, among the series of MV. tectigera, from

Brazil; they may be representatives of a new species, but more specimens must: be

examined before it can be described. This variety appears to differ from the type form

in being less elevated, with the pronotum straight or almost straight before the apex,

and the anterior white border not continued so far upwards; in shape it somewhat

resembles the preceding species.

broad, above the head, almost crescent-shaped if viewed from the side, a second in the centre of the back

extending down each side to about half the depth of the pronotum, and slightly dilated for about two-

thirds of its depth, and a third just before apex, which leaves the extreme tip of the pronotum black;

there is rather a strong sinuation just before the apex ; tegmina considerably longer than pronotum ; legs

black.

_ This genus contains a few representatives from North, Central, and South America,

which are connected with Membracis through the large and conspicuous Enehophyllum

cruentatum, the type species on which Amyot and Serville founded the genus. Stal

has subdivided the genus into three subgenera—Phyllotropis (to which E. cruentatum

must be referred, and which answers to Burmeister’s Division III. of Membracis, called

by him ‘M. foliaceo-ensate ’), Enchophyllum, and Tropidocera; the species here men-

tioned belong to the last-named subgenus.

About the same size as the preceding species, from which it may at once be distinguished by its colour and by

the slightly longer and distinctly curved horn of the pronotum, which is of a dirty whitish colour, with

the horn, a band before the apex, and the apex itself black; there are also dark markings above the head,

which is black; pronotum distinctly punctured, with the dorsal keel acute; keels at sides of horn not

extending beyond its base; shoulders slightly prominent; tegmina of a uniform tawny grey colour,

darker at the extreme base; legs dark, with the tarsi light.

Nigrum vel brunneo-nigrum ; pronoto in cornu sat longum leviter recurvum, apice supra viso haud dilatato, pro-

ducto, maculis flavis duabus dorsalibus magnis (anticé majori) interdum confluentibus, carinis lateralibus

postice vix indicatis vel totis deficientibus ; pedibus nigris, tarsis flavis.

Of a black or brownish-black colour, with two large yellow patches on the back of the prothorax, of which

the front one is the largest ; occasionally they are confluent; the anterior horn of the prothorax is rather

long and slightly curved, not dilated at the apex, carinated at the sides, with the continuation of the

carine on the hinder part of the prothorax absent or scarcely indicated; legs black, tarsi yellow.

Hab. Guaremata, Teleman in Vera Paz (Champion); Panama, Volcan de Chiriqui

As will be seen from the description, this species is somewhat intermediate between

Enchophyllum and Enchenopa ; small specimens appear to do duty in some collections

for E. lanceolata. Dr. Goding has kindly compared a specimen of it for me with his

American species and returned it as new, and near his Enchophyllum rileyi: it is some-

what variable in size and colour. . dubium is also allied to Hnchenopa albidorsum,

but that species has a straighter pronotal horn and is differently coloured. An example

from Chiriqui is figured.

Vet.-Ak. Handl. (Hem. Fabr.), Band viii. 1, p. 42 (1869).

A considerable number of American species are contained in this genus, which is

divided by St&l into three subgenera, Enchenopa, Campylenchia, and Tritropidia. The

species belonging to Enchenopa proper are very closely allied to the subgenus J'ropido-

cera of Enchophyllum, and it would perhaps be the best course to amalgamate the

genera; the chief difference lies in the cessation or continuation of the lateral carine

of the pronotum behind the horn, but this character is sometimes obscure. It is hard,

however, to define or separate the genera allied to Membracis with any accuracy, the

transition being almost complete from the large foliaceous type species of Membracis

through Enchenopa, Tropidoscyta, and Erecthia to the small seed-like species of

Bolbonota, which at first sight would certainly be considered to have no relation

whatever with the group.

I have had the greatest difficulty in identifying this species, for it appears to be

mixed with others in most collections; I believe it, however, to be a small species

closely allied to E. binotata, but with the apex of the pronotal horn not dilated at

the tip, if viewed from above, as is the case with the latter species. Say (teste

Fairmaire) appears to have regarded it as probably a variety of E. binotata, but it

appears to be distinct ; it is rightly determined by Signoret in the Vienna Museum

collection. All the specimens I have seen come from the southern portion of Central

America or from South America; the examples referred to it from more northern

localities belong to £. binotata.

This insect appears to be widely distributed, from Quebec to the State of Panama,

and to be one of the most abundant species of the genus; further south its place is

gradually taken by HE. lanceolata, from which it may be known by the dilatation of the

apex of the prothoracic horn, which is usually oblong and curved and bears a miniature

resemblance to a swan’s neck and head. A specimen from San Gerdnimo is figured.

impossible to identify them.

There is a single specimen in our collection, referred to above as from Atoyac,

which agrees with Fairmaire’s figure of the species (J. c. t. 4. fig. 32). I am inclined

to think that EZ. minans is merely a smaller and darker form of £&. binotata. The

Atoyac example is figured.

There is a specimen in our collection, from Bugaba, Panama, which must apparently

be referred. to this species, but it has the pronotal horn a little longer and more

curved, and the large yellow dorsal patch divided by a dark marking; at all events

it appears too nearly allied to admit of a separate description. A specimen from

Black ; head subquadrate, with the anterior edge almost truncate, slightly sinuate at the sides; pronotum

black, rather strongly punctured, with the lateral keels strongly marked and uneven, and with the sides,

especially near shoulders, strongly rugose; a fine raised line runs underneath from the head to the apex

of the pronotal horn, which is stout and slightly curved, and has the carine at the sides very distinct ;

This species superficially resembles E. monoceros, but differs in colour, sculpture,

and shape of pronotal horn; and also in the colour of the tegmina, which in £. mono-

ceros are unicolorous dark ferruginous, with a clear hyaline patch at the apex.

Elongate, castaneo-ferruginous, with the pronotum finely pubescent and closely punctured, produced into a horn

which is longer than the remainder of the pronotum, and forms almost a straight line with it, and is broad,

_ rounded at the tip, and furnished with five more or less distinct carinew on each side; lateral carine

preceding species; legs ferruginous.

This species resembles £. sericea, but may at once be distinguished by the much

longer pronotal horn, which is furnished with more carine, by its finer pubescence and

the colour of the tegmina.

America !, Venezuela 2 3 4,

This is a very puzzling species, and appears to present several different forms; the

extreme varieties look very different, but in a large series they lead one into another

by a perfect gradation. I thought at first that two species at least might be sepa-

rated on the presence or absence of the pronotal horn, but in some specimens it is

well marked, though short, in others it is rudimentary, and in others entirely absent:

the colour, too, is variable ; the upper surface of the pronotum is black or more or less

ferruginous with two light markings, one dorsal and one just before the apex; at the

*22

sides below these markings there is a space which is more or less broad and reddish

or yellowish, the colour being in some specimens slightly marked, while in other cases

it extends over a great part of the pronotum; the abdomen and legs are sometimes

bright red and sometimes black or dark ferruginous.

I have, with some hesitation, assigned all the specimens before me to E. quadricolor ;

at first I was inclined to refer them to E. curvicornis, but Walker’s type in the British

Museum is immature and has the horn broken off, and it is almost impossible to identify

it with any accuracy. We figure a typical #. guadricolor from Chilpancingo, and one

of the var. with pronotal horn from Guatemala city.

This is a small dark species, with the apex of the tegmina hyaline and the tarsi

pale; superficially it resembles a Zropidoscyta rather than an Enchenopa, but Stal is

probably right in including it in the latter genus.

the following species of Walker (List of Homopt. Ins. ii. pp. 488-491)—. antonina,

E. venosa, E. densa, E. frigida, and E. bimaculata ; the subgenus bears much the same

relation to Enchenopa proper as Argante bears to Aconophora. . nutans belongs to

Stal’s subgenus Campylenchia (Kongl. Sv. Vet.-Ak. Handl. Band viii. 1, p. 43). A

This genus was formed by Stal to include Membracis pecila, Germ., and other allied

species; they are small inconspicuous insects: in several points they are closely akin

* It may be noticed that in some of the figures the antennal sete are not represented; they are probably

always present in the living insect, but are extremely easily rubbed or broken off, and are therefore absent

in the majority of preserved specimens. It is possible that good characters may eventually be found in their

position ; in some of the larger species of Membracis they seem to be situated in distinct scrobes, (Vide Tab. I.

figg. 1, 2.)

TROPIDOSCYTA. . 13

to Enchenopa; the prothorax, however, is not foliaceous, and is, as a rule, rather

broad if viewed from above; the front part of the prothorax is either rounded or

produced into a very obtuse point, and is never furnished with a projecting horn, and

the back is strongly carinate. About a dozen species have hitherto been described from

North, Central, and South America. It appears to be the best course to divide the

genus further, and I have therefore assigned generic value to Tropidoscyta gibbera,

Stal, and to 7. pallidipennis and T. cornutula, Stal. In subdividing Stal’s genera a

difficulty is caused through his often omitting to state what his type is; this, and the

omission of the references in his tables, and the fact that he appears often to have sent

out species under MS. names, and not afterwards described them, tends much to lessen

the value of some of his work, and to cause great confusion and unavoidable mistakes.

There are certain species in Signoret’s collection which I fail entirely to trace, although

it is of course possible that descriptions may have been published somewhere, and the

same is the case with two or three genera; as undoubtedly some are MS. names, it is

probable that the others are also.

Membracis torva, Germ., may be taken as the typical species of Tropidoscyta, and

M. pecila, Germ., belongs to the same genus; the tegmina have three discoidal cells.

1. Tropidoscyta salla#i, sp.n. (Tab. I. figg. 19, 194.)

Fusco-ferruginea vel fusca, flavescenti-pubescens ; pronoto fortius punctato, antice lato, postice angustato, apice

quibusdam minoribus instructo; metopidio a latere viso fere recto; tegminibus fuscis parte apicali

hyalina, venis conspicuis; pedibus fuscis.

Short, broad in front, much narrowed behind, fusco-ferruginous or ferruginous, with the apical portion of the

tegmina abruptly hyaline and the apex mucronate. The central carina and one or two on each side are

strongly marked, and over each eye there are several small carine; the metopidium, if viewed from the

side, is almost straight, but projects a little further forward at its highest point in some specimens than in

others ; the surface of the pronotum is clothed with rather spare yellowish pubescence, and is moderately

strongly punctured ; the legs are fuscous.

Hab. Mexico, Orizaba (Bilimek, in Mus. Vind. Ces.); GuaraMaLa, San Gerénimo

This insect is identical with a specimen in the Vienna Museum collection named

Bolbonota sallwi, of which I can find no published description. It appears to be

somewhat variable in size and in the sculpture cf the prothorax, the front part of

which is more produced in some specimens than in others. An example from San

Feliz is figured.

Since writing the above I have examined a specimen of Membracis pecila, Germ.,

which is placed in the Vienna Museum collection under Bolbonota. It is closely allied

to this genus, but differs in its much slighter pubescence and the almost total absence

of carine above the dorsal ridge of the shoulders.

Very like the preceding, but smaller and shorter, black or almost black in colour, with the pronotum very

coarsely punctured, and with the lateral carine above the eyes strongly marked ; the tegmina are entirely

sometimes almost obsolete in the middle. The type of the genus is Zropidoscyta

This species is closely allied to the preceding, but differs in having the front of the

pronotum more porrect and extended into a very short blunt horn. It is quite possible

that they may be sexes of one species; but I have only been enabled to examine one

specimen of each.

the eyes show no trace of carine ; the tegmina are black, dull in the middle, strongly punctured towards

the base, except on the central basal area, with the apical third or fourth part very abruptly and clearly

hyaline, the line being drawn straight across at right angles to the apex of the prothorax; legs black,

with the tarsi and knees lighter or entirely fuscous.

Long. 4 millim.; lat. int. hum. 2 millim.

This is a very distinct little species, and differs considerably in appearance from the

two preceding.

TYLOPELTA, gen. nov.

Genus Tropidoscyte affine, sed pronoto maxime inequali et gibbero areisque tegminum (discoidalibus tribus,

apicalibus quinque) minus oblongis.

Allied to Tropidoscyta, but distinguished by the extremely uneven outline of the

pronotum, which is level or almost level in the last-mentioned genus, but in the present

genus is deeply and broadly excised in the middle and again before the apex; besides

the central and two side carine there is only one short and broad carina above the

eyes; the tegmira have the areas less oblong.

Panama, Volcan de Chiriqui (Champion).

Through the kindness of Dr. Aurivillius I have been enabled to verify this insect by

comparison with one of Stal’s types of Tropidoscyta gibbera, which he records from

Texas. There are specimens in the Vienna Museum collection labelled ‘‘ arcuata,

from Mexico,” and one labelled “ arcuata det. Signoret,” without any indication of the

genus, except that it appears by its position to be referred to Bolbonota ; it is, how-

ever, nearer to Tropidoscyta than to the last-named genus, and certainly seems worthy

of generic rank. We figure a specimen from Teapa.

BOLBONOTA.

Bolbonota, Amyot et Serville, Hist. Nat. des Ins. Hémipt. p. 537 (1843); Fairmaire, Ann. Soc.

Ent. Fr. sér. 2, iv. p. 257.

The members of this genus are small, dark, globose insects which, in a state of rest,

fold their legs close against their body and look just like round black seeds. No insect

could look more unlike the foliaceous species of Membracis, and yet, so gradual and so

complete is the transition through intermediate species, that the older authors included

them under the same genus. Four species of Bolbonota form Germar’s division D,

16 HEMIPTERA-HOMOPTERA.

*Gibbose,” of the genus Membracis [v. Rev. Ent. Silb. iii. p. 229 (1835)], and he

concludes his remarks regarding them with the following observation, which applies

with equal force to many other of the genera and species of the Membracide :—“ Species

divisionis ultime ita ab illis primee divisionis recedunt, ut proprii generis typos credas,

sed in characteribus gravioris momenti conveniunt, et omnes quatuor divisiones formis

intermediis inter se coherent. Stethidii diversitates semper caute queras, ne tot genera

quot species exstant condas!”

Owing to the close resemblance that the species of Bolbonota bear to one another

and the meagreness of the descriptions of many of the types, the difficulty of deter-

mining them rightly is very greatly increased, and very little is really known about the

genus as a whole, which appears to contain a considerable number of species from

Central and Tropical South America. ‘They are, as a rule, very scantily represented

in collections: in our collection there are large series of two or three species, which

appear to vary considerably in size, colour of elytra, and (to a certain extent) in

sculpture; and it is most probable that when the group is more worked and further

material collected, several of the species already described will be found to be

identical.

Dr. Goding (Canad. Ent. xxv. p. 55) separates the genus into two subgenera as

follows :—

Posterior process of pronotum behind middle furnished with a high

transverse tubercle or spine, more or less compressed antero-poste-

riorly ; anterior part strongly and gradually elevated up to middle. Tubercunota, Goding.

Posterior process from apex, seen from side, depressed; in front of

depressed part dorsum straight or lightly bisinuate . . . . . Bolbonota, A. &S.

This distinction makes a good division in most cases, although certain species appear

to be transitional ; in examining the dorsal ridge the insect must be held perfectly

upright and viewed exactly from the side.

Through the kindness of Herr Handlirsch 1 have been enabled to examine typical

specimens of several of Signoret’s species in the Vienna Museum (referred to by

Fairmaire}, which has been a great help towards determining the new species; but

there are several of the species which have been described that I have not been able to

see, and it is impossible to know what they are from the descriptions. A short mono-

graph of the genus is much to be wished for, but no satisfactory one can be drawn up

without an examination of all the types hitherto described and of larger series of the

species than are at present available. .

So far as I know, only one species has hitherto been recorded from any locality

further north than Bogota. This is B. aurosericea, recently described by myself

from a specimen in the Vienna Museum labelled “North America” (Trans. Ent. Soc.

Lond. 1894, p. 417).

carina is crossed by several minute transverse carine, and the carine of the front are much interrupted

where it is abruptly declivous, the apex being very short and blunt ; tegmina varying in colour, fuscous-

black with a few white spots, or fusco-testaceous with the apex and base darker, or yellowish with the

base reddish-brown and the apex fuscous ; the apical margin, however, is without a distinct hyaline patch

or mark ; legs black, tarsi testaceous or piceo-testaceous.

This species appears to be of about the same size as the B. globosa of Fairmaire,

described from “Colombia.” I have not seen an example of that species, which is

referred to as being in “ Coll. Spinola;” but the fact of the “caréne médiane” of the

seems to show that it is not the same as this

species. In the case of some of his species, Fairmaire appears to have assigned rather

prothorax being spoken of as ‘unie’

too great a length to them. ‘The specimens of &. insignis figured are rather extreme

varieties, but intermediate forms connect them: fig. 2 is taken from an example with

dark tegmina from Atoyac; fig. 3 from one with light tegmina from Teapa.

2. Bolbonota cuneata, sp.n. (Lab. II. figg. 4, 4a, 46.)

Brevis, nigra, nitida, alte sculpta; precedenti affinis, sed multo minor, pronoto cuneiformi, antice latissimo,

postice fortiter angustato, dorso a latere viso antice leviter sinuato, fere recto, deinde mox ante apicem

abrupte declivi; tegminibus plus minusve late ad medium albido-hyalinis, margine apicali unicolori,

fumoso ; pedibus fusco-nigricantibus, tarsis dilutioribus.

A short, broad, black, and shining species, coarsely and deeply sculptured ; allied to the preceding, but

easily distinguished by its much smaller size and the cuneiform shape of the pronotum, which is widest

in front and strongly narrowed behind; dorsum, if viewed from the side, only slightly sinuate, compara~

tively straight, strongly depressed just before the apex; tegmina black, with the central part more or less

hyaline, the dark and thick veins excepted; apical margin almost unicolorous, without distinct hyaline

spot—this, however, is traceable and may be more distinct in other specimens; legs black or piceous,

with the tarsi lighter.

This is a species very distinct from any I have yet seen. We figure an example

from Bugaba.

3500 feet, Volcan de Chiriqui 2500 to 4000 feet (Champion).—Soutu America, Cayenne},

Brazil 1.

This species, of which we have received a large series from Chiriqui, appears to be

very variable in size and to a certain extent in sculpture and in the colour of the

tegmina. The largest specimens are about 34 millim. in length; they are dull black,

fuscous-black, or brownish insects, with the dorsum, if viewed from the side, almost

straight until just before the apex, where it is abruptly depressed. The elytra are

dark, with yellow or whitish spots, and with the apex distinctly hyaline; in one

example from Panzos in Vera Paz the yellow colour covers the whole centre of the

tegmina, and the dorsum is less abruptly depressed than is usual with the species.

On an examination of typical specimens from Signoret’s collection I have little doubt

but that B. nisus, Germ., and B. pictipennis, Fairm., are identical; if this is the case,

the first name must be adopted. As, however, Signoret’s specimens are somewhat

broken and imperfect, I prefer to leave the species as they are for the present.

Walker’s Tetraplatys atomarius (List of Homopt. Ins. ii. p. 510) is either this or a

closely-allied species.

Var. levior.

Minor, levior, minus rugosa, apice pronoti evidenter magis prolongato.

Closely allied to the type form, but differs in being smaller and less rugose, with the apex of the pronotum

evidently more prolonged.

Long. 24-3 millim.; lat. max. 2 millim.

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

It is possible that this may be a distinct species, but in the large series of the type

form and the variety from the Volcan de Chiriqui the gradations are so regular that it

is very difficult to divide the variety from the type, although no one would hesitate in

describing the extreme examples as distinct. The smallest examples are only about

24. millim. in length.

Besides the examples above referred to there are two specimens from San Juan in

Vera Paz (Champion) which appear to belong to this variety, although they differ

slightly in one or two particulars.

4. Bolbonota inconspicua, sp.n. (Tab. II. figg. 5, 5 a.)

BOLBONOTA. Ie

abrupte declivi; tegminibus piceis, maculis albidis parvis in medio notatis, margine apicali hyalino ;

pedibus nigris, tarsis testaceis vel piceo-testaceis.

A very small short species, rather dull, thickly but distinctly punctured, and sparingly but distinctly pubescent ;

pronotum with the central carina and two lateral carine between this and the shoulders regular and

distinct ; dorsum, if viewed from the side, nearly straight until just before the apex, where it is abruptly

depressed ; tegmina dark, with small whitish or yellowish spots, and with the apex distinctly hyaline on

the margin ; legs black or pitchy, with the tarsi brighter; occasionally the tegmina have no distinct

small spots, but are light in the central portion.

Long. cum tegm. 2 millim.; lat. max. 14 millim.

Hab. Mexico, Atoyac in Vera Cruz, Teapa in Tabasco (H. H. Smith); Guatemata,.

El Tumbador (Champion).

This species appears to be closely allied to the smaller specimens of the var. levior

of B. pictipennis, but has the prothorax shorter and broader in proportion, with a

more blunt and shorter apex. An example from Teapa is figured.

5. Bolbonota corrugata, sp.n. (Tab. II. figg. 6, 6 a.)

Nigra vel fusca; quoad formam B. insign? affinis, sed multo minor; dorso magis distincte tuberculato, a latere

viso multo magis inequali, pone medium, iterumque ante apicem brevissimum abrupte declivi; tegmi-

nibus nigris aureo-sparsis, vel parte toté media, venis crassis exceptis, aurea vel albid&; pedibus nigris vel

piceis, tarsis flavescentibus.

In general form very like B. insignis, but considerably smaller, with the sculpture of the pronotum, if viewed

from above, proportionally stronger, and the dorsum, if viewed from the side, plainly tuberculate just

before the middle, then strongly and sinuately depressed, and tuberculate and again depressed before the

apex ; tegmina varying—dark with yellow or whitish spots, or with the yellow or whitish colour prevailing

in the centre, their apex usually with a small hyaline patch externally, which is sometimes indistinct.

Long. 34 millim.; lat. max. 23 millim.

Hab. Panama, Taboga I., San Miguel in the Pearl Is. ( Champion).

A specimen from Taboga Island is figured.

Var. minor.

Minor, minus nitida, densius minutiusque punctata; tegminibus ut in forma typicali maxime variantibus,.

interdum fere totis flavescentibus.

Very like the type form, with which it is identical in the sculpture of the dorsal ridge, but smaller, less

shining, and more thickly and closely punctured ; the tegmina are very variable in colour, being some-

times almost entirely yellow, and at others dark with yellow spots.

Long. cum tegm. 3 millim.; lat. max. 2 millim.

Hab. Brrvish Honpuras (Blancaneaur); Panama, Bugaba, Volcan de Chiriqui, and

Caldera (Champion).

I had described this insect as a new species, but on close examination I cannot detect

any structural difference between it and the type form, although the punctuation and

general sculpture are somewhat different. Two of the specimens from Bugaba are

duller and more pubescent than the others.

Had. Panama, Taboga I. (Champion).—Brazit }.

The single specimen ( ¢ ) from Taboga I. in our collection is more strongly sculptured

and more shining than any of those from Brazil in the Belgian Museum, which are the

only ones I have seen, and it may belong to a separate species; it is, however, very

closely allied to B. inegualis in the general form, the shape of the dorsal ridge of the

pronotum, and the peculiar colouring of the tegmina (which are entirely hyaline, with

the exception of the base and the veins), and can hardly be described as distinct on a

single specimen. It is also allied to B. pusio in the colour of the tegmina; but the

latter insect differs from B. inequalis in having the thorax rather longer and less broad

proportionately in front, and the ridge of the dorsum not tuberculate.

B. corrugata and B. inequalis belong to Dr. Goding’s subgenus Zubercunota ; all

the others above noticed must be referred to Bolbonota proper.

BOLBONOTODES, gen. nov.

Genus Bolbonote affine; capite longo, antice rotundato, metopidio irregulariter rugose carinato, a latere viso

fere recto, dorso supra viso maxime inequali, sed carina dorsali a latere visi fere recté ante apicem

abrupte declivi, apice breviter mucronato; tegminibus areis apicalibus quinque, discoidalibus quatuor,

alis areis apicalibus quinque, instructis ; pedibus anticis intermediisque valde dilatatis.

Allied to Boldonota, but larger, with the whole upper surface very uneven and

tugosely carinate, especially in front; the tegmina have five apical and four discoidal

areas and the wings have five apical areas—in Bolbonota the numbers are five, two, and

four respectively ; the dorsal ridge is straight and even if viewed from the side, but a

little before the apex is abruptly and almost perpendicularly declivous, the apex itself

being short and mucronate.

1. Bolbonotodes ganglbaueri, sp. n. (Tab. II. figg. 8, 8a, 83.)

Brunneo-testacea, spatiis quibusdam depressis obscuris; pronoto maxime inequali, sat fortiter remotius

instructa, his antice ad carinam centralem conjunctis, apice acuto, fusco; preeterea carinis quibusdam et

depressionibus irregularibus ; tegminibus variegatis, margine ad partem albido; pedibus abdomineque

fuscis, tarsis dilutioribus.

Testaceous or brownish testaceous, with the depressions on the prothorax, which is very uneven and rugosely

carinate, darker, of a brownish-black colour; the central carina is complete and, if viewed from above,

forms a small point over the metopidium, which, if viewed from the side, is almost straight; on either

side of the central carina is a semicircular carina with the circular parts opposed and meeting at the

central carina, the ends joining two lateral carine which are continued and meet in front; between these

carine are deep depressions ; tegmina testaceous, variegated with whitish and blackish patches, and with

the edge partly whitish hyaline ; legs and abdomen fuscous, tarsi lighter.

Long. 6 millim. ; lat. int. hum. 4 millim.

obtained from a description. |

Philya, Walker, List of Homopt. Ins., Suppl. p. 126 (1858).

Aichmophora, Stal, Kongl. Sv. Vet.-Ak. Handl. Band viii. no. 1, p. 39 (1869).

This peculiar genus is described by Walker as being ‘“‘ Enchenope affinis ;” in several

points, however, it is more closely allied to Spongophorus, although it may certainly

be regarded as affording a connecting link between the two genera. I believe that

Azinia, Walker (Ins. Saunders., Homopt. p. 63), is very closely allied to or identical

with this genus; the single specimen on which its only species, A. pallidipennis, is

described is very like Philya vitreipennis, but it is very much broken and can hardly

be identified. The locality is given as “ China,” but it is possible that some mistake

may have been made on this point. Stal has completely overlooked Walker’s genus.

1. Philya lituus, sp. n.

Elongata, angusta, unicolor, fusca vel fusco-ferruginea; pronoto in cornu prelongum ad apicem reflexum et

dilatatum et utrinque carinatum prolongato, fortiter rugosius punctato, humeris vix prominulis; dorso

acute carinato pone humeros angustato et ad apicem posteriorem subparallelo, apice ipso obtuso ; tegmi-

nibus fuscis, fere totis intectis ; tibiis dilatatis.

Elongate, narrow, of a uniform fuscous or ferruginous fuscous colour, with the pronotum very coarsely punc-

tured, especially in front, and produced into a long thick horn (about as long as the rest of the body),

which is curved upwards before the apex, and at the apex is dilated; the dilatation, if viewed from above,

is bordered and furnished with a carina, which is continued down the metopidium ; the dorsal carina is

strong, and on either side of the horn is a carina which ceases before the shoulders and apex, and below this

on each side a second carina, the latter pair meeting in front and forming the border of the dilated part

of the apex of the horn; behind the shoulders, which are scarcely prominent, the pronotum is narrowed

and is subparallel to its posterior apex, which is blunt; the greater part of the tegmina, which are of a

uniform fuscous colour, is exposed, and a considerable portion is visible from above at the sides of the

pronotum ; legs fuscous, with the tibia moderately dilated.

Long. 11 millim.; lat. int. hum. 2 millim.

Hab. Mexico (coll. Signoret, in Mus. Vind. Ces.).

Allied to P. bicolor, Walk., but differently coloured, with the punctuation coarser,

the back of the pronotum more uneven, and the horn more curved before the apex.

2. Philya vitreipennis, sp. n.

Precedenti affinis, sed multo minor et angustior, ferruginea, pronoto minus fortiter punctato, cornu magis

ascendente, et processu postico longiori et tenuiori ; tegminibus liberis, hyalinis, venis dilute testaceis ;

Much smaller and narrower than the preceding, with the prothorax ferruginous, less strongly punctured, and

with the posterior process longer and more slender ; tegmina free, hyaline, with the veins light testaceous ;

legs testaceous, with the front and middle tibie strongly, and the hinder tibie slightly, dilated.

Long. 8 millim. ; lat. int. hum. 17-13 millim.

Hab. Mexico, Paso del Macho (3), Orizaba ( 2 ) (Bilimek, in Mus. Vind. Ces.).

The male has the posterior apical process of the prothorax much more elongate than

in the female and differently shaped.

Among the unnamed species in the Belgian Museum collection there is a large

series of a species from Botafogo and Rio Janeiro which is very closely allied to this

insect ; it is, however, rather larger and darker.

8. Philya minor, sp. n. (Tab. II. figg. 9, 9 a, 94.)

P, vitrepenni maxime affinis, sed minor, cornu tenuiori, multo magis porrecto et rectiori, lateribus parallelis,.

apice supra Viso vix dilatato et tegminibus totis brunneis facile distinguenda.

Rather smaller than the preceding, from which it may easily be known by the much straighter and more

slender pronotal horn, which is very slightly dilated at the apex; the colour is a uniform testaceous-

brown, with the horn a little darker towards the apex and the wings vitreous; the femora also are dark ;

the tegmina are strongly punctured towards the base.

Long. 6-7 millim. ; lat. int. hum, 1-13 millim.

minime dilatato; sculptura leviori, tegminibusque totis hyalinis venis minus crassis, testaceis, facile:

distinguenda.

Of about the same size as the preceding, but easily distinguished by the form of the pronotal horn, which is

shorter, broader at the base, and gradually narrowed to the apex, which, viewed from the side, is rounded

off into a blunt point, and viewed from above is only just perceptibly dilated; the general sculpture is.

finer, and the tegmina are clear hyaline with fine testaceous veins; in the latter character (the vitreous.

tegmina) it is allied to P. vitretpennis, but is totally distinct from that species, which has the pronotal

horn much broader and moz® curved and quite differently formed at apex ; the colour of the prothorax is

testaceous.

Long. 6 millim.; lat. int. hum. 17 millim.

Hab. Mexico, Chilpancingo in Guerrero 4600 feet (A. H. Smith).

One broken specimen in the Vienna Museum, labelled Mexico (Bilimek), appears.

also to belong to this species.

P. dubia is very closely allied to Scalmophorus reticulatus, but it presents a trace of

the peculiar dilatation of the upper part of the apex of the horn of Philya, and the

tegmina of the elytra are intermediate in form; the whole arrangement of this group

is in a very uncertain state at present.

carinato, dorso fere quali; tegminibus reticulatis, areis apicalibus novem vel decem, discoidalibus decem,

‘Of a narrow diamond shape, if viewed from above, with the pronotum narrowed to a point before and behind,

carinate and rather strongly punctured, with the anterior horn robust, broad at the base, and gradually

narrowed to an obtuse point at the apex, with the apex straight or very slightly deflexed, or reflexed if

viewed from the side, if viewed from above or at the side not dilated, but constricted on its anterior

portion a little before the extreme point, the posterior process long, slender, impressed on either side, the

dorsum almost level throughout; tegmina strongly reticulate, with nine or ten apical areas and ten to

fifteen or seventeen diseoidal areas ; wings with four apical areas; tibiz dilated.

Allied closely to the latter species of the preceding genus, but separated by the shape

of the pronotal horn and the very strongly reticulate tegmina. Stal’s chmophora

curvicornis appears from his description to be in several points allied to this species,

but he speaks of the pronotal horn as “ valde nutans,” and mentions nothing about

the peculiar reticulation of the elytra.

1. Scalmophorus reticulatus, sp. n. (Tab. II. figg. 11, 11a, 118.)

Brunneus vel testaceo-brunneus, unicolor, cornu pronoti ad latera subrugoso, cariné dorsali testaceé, brunneo

variegaté ; tegminibus brunneo-hyalinis, basin versus punctatis ; pedibus plerumque nigricantibus.

Of a unicolorous brown colour, with the head closely and finely punctured, and the pronotum strongly punctured

and carinate, the keel extending beneath the horn; tegmina brownish-hyaline, punctured towards the

base, except in the centre; legs mostly black or fuscous.

Long. 74 millim.; lat. int. hum. 2 millim.

Hab. Guatemata, San Gerénimo 3000 feet, Cerro Zunil 4000 feet (Champion).

The specimen from Cerro Zunil has the prothoracic horn more evenly pointed and

the elytra more strongly reticulate ; it may belong to a separate species, but this cannot

be decided without further material. We figure the example from San Gerdnimo.

This genus contains a considerable number of insects, which have been divided by

Stal into four subgenera, Notocera, Pterygia, Hypsoprora, and Achmophora; of these,

Pterygia and Notocera can hardly be separated, and the type forms of Achmophora

must be referred to Walker's Philya, and appear entirely distinct from the form classed

by Stal under Notocera. The species below included under Pterygia are rough, scabrous,

tuberculate, or partly spinose insects, with a pair of strong horns or processes in front

of varying length, and with the back furnished with two or three larger or smaller

protuberances, which are blunt or rounded at the apex. All the known species

belonging to the genus appear to have been hitherto described from tropical South

America.

2. Pterygia bituberculata, sp. n. (Tab. II. figg. 13, 13 a.)

Brevior, fusco-nigra, vestitu albido dense induta, variegata ; capite oblongo latitudine multo longiori ; metopidio:

ad basin cornuum bituberculato, his brevibus, robustis, latis, truncatis, apicibus latis excavatis ; pronoto

A rather short and robust species, of a fuscous black colour, clothed more or less abundantly with a clear white

serration, which is also present on the legs and tegmina, and is more or less fugitive; head long, metopidium

set with scanty short spines and with a distinct tubercle on each side near the base of the horns; the latter

are short and broad, truncate at the apex, with the apex excavate, subtriangular if viewed from above and

pointed at the angles; a spinose carina runs from the apex of the metopidium to the apex of the pronotum,

which is strongly, though more or less remotely, punctured, and is furnished on the dorsum with a

somewhat irregular spinose tubercle between the base of the horns, and a larger one, rounded at the

apex, a little behind the middle; from this point the apex is gently rounded; the tegmina are fuscous,.

broadly and more or less obscurely variegated with testaceous, and the legs are dark with the tarsi

yellow ; the whole surface is scabrous and sparingly set in certain parts with short stout spines.

This species is very closely allied to P. hispida, but the horns are more divaricate and

broader at the apex, and the dorsum is bituberculate. The single specimen of P. hispida

which I have seen has the hinder part of the pronotum wanting, but Fairmaire

(2. c. p. 265) expressly says ‘‘ prolongement postérieure portant trois élévations.” An

example from San Juan in Vera Paz is figured.

3. Pterygia cerviceps, sp.n. (Tab. II. figg. 12, 12a.)

Praecedente major, fusca, plus minusve distincte albido-vestita ; capite latitudine longiori ; metopidio supra viso-

Larger than the preceding, black, fuscous, or testaceous, according to maturity, more or less distinctly clothed

with a whitish secretion, but not so strongly as in the preceding species ; head long, metopidium, if viewed

from above, continued for some distance in front of the horns, which are very long, recurved, much dilated,

truncate and excavate at: the apex, the hinder angles being sharp; dorsum with three protuberances, the

first of which is slight and marked by long thick spines, the second the highest, broad and rounded, and

the third like the second but smaller and not so broad in proportion at the apex’; a spinose carina runs

Hypsoprora, Stal, Ofv. Kongl. Vet.-Ak. Férh. xxvi. p. 277 (1869).

Achmophora, Stal, loc. cit. p. 278 (ex parte). ;

The type-forms of Stal’s subgenus Achmophora (4. elephas and 4. recticornis) must

be referred to Walker's genus Philya; but Achmophora coronata, Fabr. (= Pterygia

varia, Walker), seems to be closely related to certain forms of Hypsoprora, and I have

therefore placed it under that genus, together with the other species of Pterygia which

have no horns at the side of the pronotum above the shoulders. In all these forms the

pronotum is more or less extended in front into an erect process, which in some cases is

broadly rounded and very obtuse, and in others very much elongated; this process is

wanting in the species of Pterygia proper.

The specimen from Bugaba may belong to a:distinct species, as it is smaller, with the

pronotum narrower, and differs somewhat in the relative size of the dorsal protuber-

ances ; without further material, however, it can hardly be regarded as separate. A

Mexican example is figured.

2. Hypsoprora nigerrima, sp.n. (Tab. II. figg. 14, 14a.)

Tota nigra; capite levi, distincte punctato; metopidio tuberculato; pronoto scabro, fortiter punctato, rugoso,

tuberculate ; pronotum rugose and coarsely punctured, with the dorsum more or less strongly sinuate, and

divided into three elevations, which appear o vary in size and elevation in different specimens, the hinder

one being the broadest and least elevated, and, if viewed from above, dilated strongly behind ; tegmina

‘In the type-specimen the dorsal prominences are very little elevated: it is possible

that the specimens from Atoyac, in which they are much more elevated, may belong to

a different species; if viewed from above, however, they are almost identical, and they

can hardly be separated until more material is discovered ; the difference is not sexual.

whitish secretion ; pronotum scabrous, thickly and distinctly punctured, produced in front into a long

erect process, which i is strongly sinuate externally and dilated in the middle, and then rounded and slightly

recurved before the apex, presenting the appearance of the outline of a duck’s head; in some cases, how-

ever, the sinuation appears to be not nearly so marked, and the sides are subparallel; the distance from

the front edge of the metopidium to the apex of the process is about equal to the distance from the same

to the apex of the tegmina; there are no dorsal protuberances ; the tegmina are opaque and ferruginous,

and the legs reddish.

This species is of about the same size as the preceding ; it has the apex of the short

pronotal process shaped much as in Philya, but in other respects is more closely

related to. Hypsoprora; it may, perhaps, form the type of a separate genus. An

example from the Volcan de Chiriqui is figured.

SPHONGOPHORUS.

Sphongophorus, Fairmaire, Ann. Soc. Ent. Fr. sér. 2, iv. p. 261 (1846); Stal, Ofv. Vet.-Ak. Forh.

XXvi. p. 273 (1869).

This genus contains upwards of twenty species, which are all from Central or Tropical

South America: the majority, apparently, inhabit Brazil. They are among the most

extraordinary of the Membracide, and, in fact, there are few insects which assume

more curious forms; in some cases, at all events, these forms are protective, for, when

SPHONGOPHORUS. 27

at rest, many of the insects must resemble pieces of dry twigs. St&l divides the

genus into three subgenera, which may be distinguished as follows * :—

Pronotum with a very long, slender, recurved anterior process, and a

long, more or less curved, posterior process, the whole pronotum |

often forming about three fourths of a circle. . . . -Subgen. Sphongophorus, i. sp.

Pronotum with the anterior process stout, very long, and recurved ;

posterior process furnished with an erect knob, beyond which

the anterior process, which is usually simple underneath, con-

siderably projects. . . . . . «0... . . « Subgen. Cladonota, Stal.

Pronotum with the anterior process stout, shorter than in Cladonota,

sometimes erect; posterior process armed at about or behind

middle with an erect horn or knob, beyond which the anterior

process, which is always furnished with a knob or large tooth,

does not project . . . . . . . . . . . . . «Subgen. Lobocladisca, Stal.

To these three a fourth is here added :—

Subgeneri Lobocladisce valde affinis, sed processu antico pronoti _

postice simplici, semper curvato et ad clavam processus inter-—

medii extenso, hac interdum maxime inflata. . . . Subgen. Lecythifera, subg. nov.

The subgenus Lecythifera chiefly differs from Lobocladisca in having the posterior

side of the anterior process simple, in which point it resembles Cladonota, from which

it differs in the fact that the anterior process does not extend beyond the interme-

diate process. In the slender form of one or two of its species it is allied to S. ballista ;

one of them, L. inflata, has the club of the intermediate process enormously inflated,

but it is in other points so closely allied to the other species that it can hardly be

separated off as a distinct genus on this one point alone.

The Old-World genus Hypsauchenia, although it resembles Sphongophorus in some

respects externally, is really very distinct, for the legs are not foliaceous and the

tegmina are very differently veined. |

* T have made very little use of subgenera in the Membracideg : in the case of Sphongophorus, however, I

have preferred to retain the division into subgenera, at all events for the present, as, in the first place, they

lead too closely one into the other to be separated generically, and, in the second place, almost every other

species might be described a as @ new genus,

The series of this species in our collection is almost certainly the largest that has

ever been obtained, and consists of more than one hundred examples. ‘There is a

considerable amount of variation, especially in the formation of the apex of the

anterior process, which, as a rule, appears to be more or less knobbed in the males and

bifid in the females; this is not, however, a universal rule, for it is sometimes almost

simple in both sexes, and in the case of two males before me from the same locality

one is slightly bifid and the other has a very large knob. The posterior process also

differs in being narrower or broader, and more or less porrect, especially in the males ;

in fact, a series of males from Bugaba, Panama, might almost be formed into a new

species on this character, but the females appear to be quite normal.

S. claviger of Stal, of which there is a single male specimen (without abdo-

men) from Mexico in Signoret’s collection, is a rather large and robust brownish

variety of this species, of which there are several larger and more representative speci-

mens in our series from San Geronimo, Guatemala; if they stood alone they might be

regarded as distinct, but intermediate forms render it plain that they can, at the most,

be only counted a variety, and I feel no doubt but that Stal’s S. apicalis must also

be sunk as a synonym of S. ballista.

The anterior process in the female is often much longer than in the males, and is

much waved if viewed from above; this never, or only in a very slight degree, appears

to be the case with the males.

Mr. Champion captured two specimens in cop.; if the segments of the circles almost

formed by the pronotum in each case were completed, they would in this position

present nearly an exact figure of 8.

We figure examples from Atoyac (fig. 18), Teapa (fig. 19), and San Gerdnimo’

(fig. 20).

2. Sphongophorus (Lecythifera) championi, sp.n. (Tab. III. figg.1, 1a.)

S. balliste affinis; niger vel brunneo-niger ; pronoto antice punctato, processu antico et postico reticulatis ;

processu antico teretiori plus minusve alte curvato, usque vel fere ad apicem processus dorsalis extenso,

versus fusco-brunneis, macula hyalind marginali sub basi processus intermedii siti; pedibus testaceis

vel fusco-testaceis.

Black or brownish black, with the anterior process of the pronotum rather slender and curved behind until it

is almost in a line with the apex of the tegmina, widened at its apex into a subtriangular club; the posterior

prolongation extends nearly to the apex of the tegmina, ending in a short, thick, reflexed process,

SPHONGOPHORUS. 29

set at right angles to the posterior process itself; between the middle of the latter and the short apical

process there arises an intermediate somewhat hammer-shaped process, consisting of a thick club, with

the head pointing backwards, and in some cases almost meeting the apical process ; tegmina punetured,

black, fuscous towards the apex, with a hyaline spot just under the stalk of the intermediate process ;

legs testaceous or fusco-testaceous. The metopidium and the sides of the front of the pronotum are punc-

tured; the pronotal processes, however, are more or less coarsely reticulate.

Long. 6, lat. 14 millim.; alt. max. 6-8 millim.

Hab. GuatemaLa, El Reposo 800 feet, San Isidro 1600 feet (Champion).

Four specimens, apparently all males. This very distinet species is closely allied to

S. ballista, and forms a connecting-link between that species and the stouter forms of

the subgenera Cladonota and Lobocladisca. An example from El Reposo is figured.

8. Sphongophorus (Lecythifera) affinis, sp.n. (Tab. III. figg. 2, 2 a.)

Precedenti affinis, sed processu pronoti anteriori multo breviori et ad apicem simplici, haud clavata; processu

apicali clava subtriangulari, et processu intermedio clava paullo minore terminato; pedibus lete

testaceis.

Very like the preceding, but rather larger, and easily distinguished by the anterior process of the pronotum

being much shorter, much more abruptly curved, and simple at the apex, the apex being just on a level

with the club of the intermediate process, which is rather smaller; the formation of the apex of the

posterior process is different, being subtriangular ; the tegmina are produced further beyond the apex

of the pronotum, and the legs are of a bright testaceous colour.

Long. 7, lat. 14 millim.; alt. max. 5 millim.

Hab. Guatemata, Quiché Mountains 7000 to 9000 feet, Totonicapam 8500 to 10,500

feet (Champion).

Five specimens, apparently all males. Although this species resembles the preceding,

yet it appears to be quite distinct. The specimens of these two species in our

collection are all mounted on card, and I have not determined the sex in every case ;

but those which I have examined are males, so that the differences are not sexual.

If, however, we take into consideration the varying forms in a large series of S. ballista,

it is possible that the present species may eventually turn out to be a form of the

preceding. An example from the Quiché Mountains is figured.

The specimens from Totonicapam are unfortunately all broken, but I have no

doubt, from what is left of them, that they belong to this species.

4, Sphongophorus (Lecythifera) robustulus, sp.n. (‘Lab. III. figg. 3, 3a.)

Parvus, brunneus, metopidio utrinque dilutiori, rugosus, processu antico pronoti robusto, curvato, apice,

A small, robust, rugose species, brown, with the metopidium on each side lighter ; anterior process of the pro-

notum stout, curved, ending in a club, which is broad and bilobed, if viewed from above, in the male, and

scarcely at all dilated in the female ; the posterior process is slender, and terminates some distance before

the apex of the tegmina in a small triangular process; from the middle arises a stout stalk, bearing a

club, which is very large in proportion to the size of the insect—in the male this is thick and rounded,

but in the female it is thinner, and subrhomboidal and pointed at the apex; the tegmina are brown,

unicolorous and subhyaline in the male, somewhat mottled and more opaque in the female ; the legs are

testaceous or brownish testaceous.

Long. 44-5, cum tegm. 53-6 millim. ; alt. max. 5-6 millim.

Hab. Guatemaua (Mus. Roy. Belg.), Duefias (Champion), Aceituno (Salvin).

This distinct little species is allied to S. championi and S. affinis on the one hand,

and to the stouter brown species of the subgenus Cladonota on the other. A specimen

from Dueias is figured. :

5. Sphongophorus (Lecythifera) inflatus, sp.n. (Tab. III. figg. 5, 5 a—c.)

Nigro-brunneus vel brunneus, processu antico pronoti robusto, curvato, clavé oblongo-rotundata reticulata ;

processu postico vix ante apicem vel ad apicem processu rotundato, permagno, inflato, sessili, reticulato

instructo; apice prothoracis plerumque brevissime pone hunc prominenti; tegminibus longis ultra apicem

prothoracis extensis, brunneis, macula marginali testacea sub processu inflato sité ; pedibus testaceis.

Of a blackish-brown or brownish colour, with the anterior process of the pronotum robust, curved, and termi-

nated in an oval or almost oval club; posterior process furnished just at the apex with an enormous, round,

inflated bulb-like process, which, like the club of the anterior process, is reticulate and finely sculptured

in the interstices of the reticulations, and is sometimes marked with little spots of a lighter colour; this

process has no stalk, but is sessile, and the apex of the pronotum usually projects very slightly beyond it:

the tegmina are long and project beyond the apex of the pronotum, and are of a brown colour, with a

large testaceous mark on the margins just below the inflated process; legs testaceous.

Long. 9, cum tegm. 10 millim; diam. process. 6 millim.; alt. max. 7-8 millim.

Hab. Guatemata, San Geronimo (Champion).

About a dozen specimens, male and female ; the sexes do not appear to differ in any

noticeable degree. The peculiar inflated process will at once distinguish this species

from any other. In fig. 5c part of the sculpture of the inflated process is represented.

Morelos, Sayula in Jalisco, Acapulco in Guerrero (Hoge).

In this species the males and females differ considerably as regards the pronotal

processes. We figure a male from Sayula and a female from Acapulco.

There is a peculiar specimen in our collection, from Totonicapam, Guatemala,

10,000 feet, of a brown colour, and rugose, with mottled tegmina, and with the ante-

rior process almost straight and only slightly curved at the apex, which is pointed.

Unfortunately this specimen is broken and cannot be described ; but it belongs to the

subgenus Cladonota, for there is the base of a stout intermediate process remaining,

and part of a triangular apical process ; it is almost 9 millim. in length, and the height

to the tip of the apical process is 7 millim.

Subfam. HOPLOPHORINA,.

This subfamily, though not a large one, contains several important genera; they

may be known by the very short posterior tarsi, and may be distinguished as follows :—

I. Wings with four apical cells.

1. Pronotum with the lateral angles produced into sharp horns,

and with its sides more or less compressed and elevated . Triquetra, Fairm.

2. Pronotum with the lateral angles at most obtusely prominent.

sides, with the posterior process short, scarcely reach-

ing beyond apex of abdomen. . . . . . . . « Potnia, Stal.

6b. Horn of pronotum long and sharp; pronotum carinate

at sides, with the posterior process long, reaching |

almost to apex of tegmina . Doe ee Aconophoroides, gen. nov.

II. Wings with three apical cells.

1. Posterior process of pronotum not or scarcely reaching

beyond apex of abdomen ; anal cells of wings larger.

A. Pronotum narrowed evenly from shoulder to apex ; head

broader.

a. Pronotum with a stout blunt dorsal horn, inclined

forward, and situated at some distance from the meto-

pidium, sometimes reduced to a raised prominence, or

entirely wanting ; tegmina extending for about one-

third their length beyond apex of pronotum. . . . Platycotis, Stal.

back of which is exactly level with the dorsum ;

tegmina long, extending for almost half their length

beyond apex of pronotum. . . . . . . . . . Orthoplophora, gen. nov.

head narrower . . . . . . » . . « Hoplophora, Germ.

2. Posterior process of pronotum ‘long and sharp, reaching

metopidium ....... . . . 6 . « . . Umbonia, Burm.

TRIQUETRA.

Triquetra, Fairmaire, Ann. Soc. Ent. Fr. sér. 2, iv. p. 279 (1846); Stal, Ofv. Vet.-Ak. Forh.

XXvi. p. 265 (1869).

This is rather an important genus, containing about a dozen species, which are, for

the most part, recorded from Bogota; one or two occur in Venezuela and Brazil.

Triquetra is very poorly represented in Central America, except in the case of one

species, which appears to be locally abundant. ‘The species are, as a rule, rather large,

and have the humeral projections much developed, forming long pointed horns; the

front of the pronotum is in some species armed with a longer or shorter horn, and in

others merely bluntly rounded or subangulate. The insects are of the same colour in

life as the thorny plants or shrubs which they frequent, and, as they sit close to the

stalks, they may easily be mistaken (as in the case of the species of Umbonia) for

thorny excrescences, their somewhat formidable appearance being therefore merely

protective.

. The genus is allied to Umbonia, but differs in the strongly tectiform pronotum and in

the fact that the wings have four apical areas ; the humeral projections, moreover, are,

as a rule, much longer and more slender.

I have placed the above names under 7. grossa after examining a large series.

Fairmaire? himself says of 7. virgata that it closely resembles 7. virescens, and Stal

TRIQUETRA. 33

remarks, “A precedente [i.e. 7. virescens] vix differt”; TZ. grossa and T. virgata, how-

ever, are more closely allied in general appearance to one another than to 7. virescens,

which appears to be a smaller form of the male with the humeral horns rather shorter

and less slender. Among specimens in our collection from Irazu there are males just

like Signoret’s typical specimen of 7’. virescens referred to by Fairmaire (which I have

before me), and females exactly like his 7. grossa. On comparing a large series it is

evident that there is considerable variation in the length and direction and the

straightness or slight recurvation of both the dorsal and humeral horns, and that it

would be very easy to describe fresh species if it were not for intermediate forms

leading from one to the other. In the Vienna Museum collection there are only five

specimens belonging to these three so-called species, four females and one male—the

male being placed under 7. virescens, two females (which differ considerably inter

se) under 7. virgata, and two females under T. grossa. On comparing them, however,

with the series in our collection it is obvious that they must all be referred to one

species. A specimen from Panajachel is figured.

2. Triquetra veruta, sp.n. (Tab. III. figg. 9, 9a.)

Minor, fusco-brunnea ; pronoto longo, angustiori, fortiter punctato, rugoso, humeris modice prominentibus,

haud porrectis, nigris ; cornu dorsali elongato, fere recto, acuto, lateribus ab humeris angustatis, in pro-

cessum apicalem longum productis; tegminibus brunneis, venis dilutioribus, margine externo apicem

versus hyalino ; pedibus abdomineque brunneis vel fusco-brunneis.

A comparatively small and narrow species, of a dark brown colour, with the pronotum very coarsely and

rugosely punctured in irregular rows; humeral prominences moderately long, at right angles to the pro-

notum, and not extended forward; dorsal horn long and sharp, almost straight, but very slightly recurved

at the apex, ribbed at the sides; dorsal raised line continued from above the head to the tip of the horn,

and thence to the apex of the pronotum, which is long and extends considerably beyond the abdomen,

but not to the apex of the tegmina; tegmina and legs brown, the former with the veins lighter.

Long. 9, cum tegm. 10 millim.; lat. inter cornua 6 millim.

Hab. Panama (Boucard, in Mus. Holm.).

I found a male specimen of this distinct little species among some undetermined

Homoptera sent me for examination by Dr. Aurivillius; it is allied to Umbonia obscura,

Walk., but differs entirely in the shape of the humeral horns of the pronotum.

8. Triquetra apicalis. (Tab. III. figg. 11, 11 a.)

Umbonia apicalis, Walk. List of Homopt. Ins. ii. p. 518°.

Hab. Panama, Bugaba (Champion).—Co.omBIA 1.

This species may easily be distinguished from the preceding by the formation of the

humeral and dorsal horns, which are long and acute, and extended forward in front of

the head, so that, if viewed sideways, their tips are almost on a level, that of the

dorsal horn projecting rather further forward than the other. It is also allied to

Triquetra (Umbonia) turrita, Fairm.; but that insect, which inhabits Brazil, is rather

BIOL. CENTR.-AMER., Rhynch. Homop., Vol. II., October 1894. *5

34 HEMIPTERA-HOMOPTERA.

longer and broader, with the dorsal horn shorter, less porrect, and blunter at the apex,

and the humeral horns are much less porrect and recurved, so that, if viewed from the

side, they do not project beyond the metopidium.

It is possible that this species, with 7. veruta, T. turrita, and T. obscura, ought to

be placed in a separate genus; in facies they differ very much from the ordinary testa-

ceous forms of Triquetra.

UMBONIA.

Umbonia, Burmeister, Handb. Ent. ii. 1, p. 188 (1835); Fairmaire, Ann. Soc. Ent. Fr. sér. 2, iv.

p. 274; Stal, Ofv. Vet.-Ak. Forh. xxvi. p. 264 (1869).

About seven or eight species are comprised in this genus; they appear to be con-

fined to Central and Tropical South America; one species, U. amazili, is recorded by

Fairmaire from North America, but I have not seen a specimen of this insect, and Stal

omits it from his list of the genus. The species are distinguished by having the pro-

notum armed with a longer or shorter dorsal horn, and by the shoulders being more or

less acutely produced and cornute. The wings have four apical cells, and their anal

areas are minute and not lobate; the posterior process of the pronotum is continued

almost, if not quite, to the apex of the tegmina, and sometimes projects beyond them.

The genus is allied to Triquetra, but the species are, as a rule, stouter insects and less

tectiform, with the humeral processes much less developed. ‘The two species described

by Amyot and Serville (Hist. Nat. des Ins. Hémipt. p. 543) as belonging to their genus

Physoplia (P. crassicornis and P. nigrata) are really forms of the male of Umbonia

orozimbo.

The species of Umbonia, like those of Triquetra and Lanthe, frequent thorny plants,

so that the horn-like processes are distinctly protective appendages.

This species is somewhat variable in colour, but may usually be known by its

prevailing red tint, as well as by the short humeral prominences and short strongly

recurved dorsal horn, which is situated at a considerable distance behind the shoulders.

This species, of which one male specimen has been received from Chiriqui, is very

closely allied to U. ataliba, and may prove to be merely a variety of that species; it is

rather smaller, and has a black marking on the dorsal horn in front and behind, which

is sometimes absent. U. pyramidalis and U. ataliba may be distinguished by the long

sharp dorsal horn and the long convex metopidium, which arises from the fact that the

horn is set some way back between the shoulders, and forms a somewhat abrupt angle

This species seems to be very scarce in Central America, as there are only seven

specimens in our collection from six localities. St&l considers the U. spinosa of Fair-

maire to be a different insect to the U. spinosa of Fabricius, and names the former

U. curvispina ; I have only seen one specimen, in the Belgian Museum collection, and

it appears to be nothing more than a form of U. spinosa, Fabr. The older writers

speak of the insect as ‘‘sex rubro-lineata” or “avec six lignes rayonnantes,” and

of U. ataliba as “ quadrilineata.” It must be remembered that these lines are

reckoned from the tip of the dorsal horn, so that the continuous line passing over

the horn from the apex of the pronotum to the front margin of the metopidium

counts as two.

This is an extraordinarily variable species, and it is only after careful examination

of a long series that a right idea can be formed regarding it; the females vary to a

certain extent in colour, and in the size and formation of the dorsal horn, but the variation

in this sex is very slight compared with that of the male. No two insects at first

sight would seem more distinct than the large dark males with enormously deve-

loped dorsal horns, which represent the Physoplia nigrata of Amyot and Serville, and

the small males from El Reposu and Las Mercedes, and Tolé, Panama, which scarcely

differ from the females, except in being smaller and having the horn slightly thickened

and recurved; and yet in the large series in our collection (which consists of about

400 specimens) there are intermediate forms which lead gradually up from the one to

the other without a break. I examined all the specimens and determined their sexes,

as well as series in other collections, and found that in no case had the female a

strongly thickened horn; this led me to believe that U. crassicornis and U. nigrata

must be the males of U. orozimbo, and on examining large series from the same localities

it was evident that this was the case. Stal says of these two species, which he includes

in a separate division of the genus, ‘Feminas hujus divisionis haud vidi”; he identifies

Physoplia intermedia, Walker, as a form of the male of U. orozimbo, but had evidently

not enough material on which to proceed further. |

The ordinary colour of the females is greenish with yellowish or yellowish-red stripes,

but the colour is very variable, some being yellowish with dark red stripes like

U. ataliba, and others, again, reddish-brown or olivaceous; the males vary from a

UMBONIA. 37

yellowish or olivaceous tint to almost black; in the varieties with strongly thickened

horns the latter are always dark. In all the specimens, both male and female, the

lines on the metopidium have a tendency to run one into the other, and this serves

as a rough character for distinguishing the species.

It would take too much space to notice each of the series in detail, but the small

males above referred to and a small variable series of the thick-horned males from

Amula, Guerrero, are especially worthy of mention.

We figure six specimens of this variable insect: fig. 15 is taken from a female from

Jalapa; fig. 16 from a male from Amula; fig. 17 from a female from Tierra Colorada ;

fig. 18 from a female from Omilteme; fig. 19 from a male from Amula; fig. 20 from

a male from El Reposo. .

6. Umbonia orizabe, sp.n. (Tab. III. figg. 21, 21a, ¢; 22, 2.)

Parva, olivaceo-viridis vel olivacea, fusco- vel fusco-rubro radiata; metopidio longo ante cornu dorsale late

rotundato, supra caput rubro; cornu dorsali in utroque sexu brevi, acuto, recurvo, apice rubro; lined

elevata pronoti distincté, rubra, apice acuto; tegminibus hyalinis, venis fuscis vel brunneis; pedibus

testaceis vel rubro-testaceis, tarsis anticis et intermediis fuscis.

A small species, with the male and female very similar, the horn being not thickened in the former, but in

both cases short, sharp, and strongly recurved ; the colour is olivaceous, with the front of the meto-

pidium, the tip of the dorsal horn, and the dorsal elevated line red, and the rays fuscous, the broad ones

in front being sometimes reddish; the metopidium is long in front of the dorsal horn, and is shaped

much as in U. ataliba; the pronotum does not quite reach the apex of the tegmina.

3. Long. cum tegm. 84-10 millim. ; lat. inter cornua 5-53 millim.

@. Long. cum tegm. 11 millim.; lat. inter cornua 7 millim.

Hab. Mexico, Orizaba (H. H. Smith & F. D. G.).

Eleven males and seven females. I have considerable hesitation in naming this

insect, both sexes of which are figured, as it is probably only a peculiar race of

U. orozimbo, but have done so on the similarity of the sexes with regard to the short,

sharp, recurved dorsal horn and the shape of the metopidium. Among the large

series of U. orozimdo there are several small males that closely resemble this species ;

but the horns are usually larger, and in some examples at least are thickened, and the

metopidium, though variable, appears to be more sloping than in U. orizabe, and not

so abrupt before the dorsal horn.

Among some undetermined Homoptera sent me from the Stockholm Museum, I find a

ingle small specimen of an Umbonia (a female) labelled “ Mexico (Boucard),” which I

think must be referred to this species as a variety. It has the horn set far back,

and the metopidium long and rounded ; the insect is, however, rather stouter, with

bright orange instead of fuscous rays, and the legs are testaceous, with orange markings.

It may belong to a new species, but 1 should not care to describe it on a single

specimen.

Hab. Mexico, Valladolid and Temax in Yucatan (Gaumer), Campeachy!.

About twenty-five examples, all, with one exception, females. This species appears

to belong to Umbonia, although it differs from the other members of the genus by its

broad, compressed, perpendicular horn. U. gladius appears to be either rare or very

local, for I have not seen it in any other collection. I have not had the opportunity

of examining the type-specimen which Fairmaire records as in Guérin’s collection, but

his description and figure easily admit of identification. The single male specimen

above referred to is much smaller than the females, with the dorsal horn shorter, and

the pronotum only slightly reaching beyond the abdomen, and the tegmina projecting

considerably beyond its apex.

A specimen from Valladolid is figured.

| HOPLOPHORA.

Hoplophora, Germar, Rev. Ent. Silb. iii. p. 240 (1835) ; Fairmaire, Ann. Soc. Ent. Fr. sér. 2, iv.

p- 269; Stal, Kong]. Sv. Vet.-Ak. Handl. Band vii. 1, p. 37; ibid. Ofv. Vet.-Ak. Férh.

XXV1. p. 264 (1869).

This genus, as restricted by Stal, contains about a dozen species from Central or

Tropical South America, and one is recorded by Fairmaire from North America; they

are stout and broad insects, varying considerably in size, with the pronotum short and

shield-shaped, sinuate behind the horns, which are short and blunt, then nearly parallel

for a certain distance, and then gradually narrowed to a sharp point, which scarcely

reaches the apex of the body; the tegmina are much longer than the pronotum, and

are furnished with long, more or less oblong areas, bounded by distinct thick veins ;

there is no trace of a dorsal horn. The genus may be easily distinguished from Platy-

cotis (apart from the dorsal horn or process, which in the latter genus is occasionally

almost wanting) by the much narrower head and by the shape of the pronotum behind

the horns.

1. Hoplophora monogramma.

Hoplophora monogramma, Germ. Rev. Ent. Silb. iii. p. 242°.

mann), Orizaba (Bilimek, in Mus. Vind. Ces.), Oaxaca; GuATEMALA, Cerro Zunil

4000 to 5000 feet (Champion).

This species is very variable in size and colour ; it may, however, be distinguished by

the fact that the central keel of the pronotum from the centre of the dorsum to just

HOPLOPHORA. 39

above the head is black, shining, and strongly marked, and by the arrangement of the

dark spots at the base and across the middle of the tegmina. There appear to be three

well-marked forms—one (var. a) of a brownish colour, with dark markings; another

(var. 6) of a light yellowish-grey colour, with red markings; and a third (var. ¢) of a

more or less bright red colour, with the front of the pronotum just above the head

yellowish. This latter, as is evident from the description, is the H. sanguinosa of

Fairmaire. It varies in size from 8 to 10 millim. “cum tegminibus” ; the yellowish-

grey variety with red markings (var. 5) is apparently confined to high altitudes, all the

specimens being from places with an elevation of from 4000 to 8000 feet.

2. Hoplophora signoreti, sp. n. (Tab. III. figg. 23, 23 a.)

Lata, capite pronotoque ferrugineis, hoc unicolori, fortiter rugoso-punctato, lineis nonnullis elevatis inzequali-

basin partim flavis, maculis quibusdam nigris instructis ; pedibus ferrugineis, tarsis anticis et intermediis

nigro-fuscis.

A large species, with the head and pronotum entirely ferruginous, the latter strongly and rugosely punctate,

especially on the dorsum, and with several uneven raised lines parallel to the dorsal line, which is raised

and red throughout ; humeral projections very blunt, very slightly projecting; tegmina hyaline, with the

veins darker or lighter brown, partly yellowish at the base, with two black spots one above the other

close to the base, and an irregular band of spots across the middle; legs ferruginous, with the anterior

and intermediate tarsi black ; male smaller than female, with the veins and underside darker.

. Long. 10 millim.; cum tegm. 14 millim.

3. Long. 8 millim.; cum tegm. 11 millim.

_ Hab. Mexico (coll. Signoret).

Two specimens. These are named H. sanguinosa in Signoret’s collection, but, as

Fairmaire’s description manifestly does not apply to them but to the preceding species,

I have separated them; his description is as follows :—“ Fortement ponctué, d’un beau

rouge ; bord antérieur jaune, caréne noire antérieurement.” There is another specimen

under H. sanguinosa in Signoret’s collection, of a dark brown ‘colour, with darker

markings, and the margins of the pronotum and central line in part clear red, which

may be a variety of the preceding, though I should rather refer it to the present

species.

3. Hoplophora cinerea. (Tab. III. figg. 24, 24 a.)

This species is represented in our collection by a far greater number of examples

than any other of the genus, and it seems to have been taken very plentifully by

Mr. Champion at Teleman; it does not appear to be a common insect, to judge by other

collections. HH. cinerea may easily be known by its broad convex form, uniform brown

colour, the strongly raised dorsal lines, and the blunt apex of the pronotum, and

especially by the auriculate projections (they can hardly be called horns) at the sides

of the pronotum above the shoulders; if viewed from the front the female insect

bears a striking resemblance to a pug dog. The males are smaller than the females,

and have the humeral projections less auriculate, less developed, and more rounded

at the apex. <A specimen from Capetillo is figured. |

Var. obfuscata.

Minor, angustior, brunnea, nigro-notata vel tota fusca, humeris minus prominentibus. An nova species ?

Smaller and narrower than the type, variegated fuscous-brown with black markings, or of a unicolorous fuscous

colour, with the humeral prominences less marked and less auriculate.

Hab. GuatEMata, Zapote, Capetillo (Champion).

Three male specimens. At first sight this looks a very distinct species, and may

perhaps ultimately prove to be so, but when compared with a small male of the type-

form of H. cinerea it agrees with it structurally in’ almost every point except those

above specified. The type-specimen resembles the dark form of H. monogramma, for

it has the raised keel black in front ; it is, however, only black in front of the humeral

prominences, and the insect may be at once separated from the last-named species by the

form of the pronotum, which is short and very blunt at the apex, and has the peculiar

shape of that of the ordinary form of H. cinerea. If the female of the variety is

discovered it may be found to be distinct from that of the type.

4. Hoplophora disparipes, sp. n. (Tab. III. figg. 25, 25 a.)

Parvus, pronoto griseo vel flavo-cinereo, nigro-notato, sat dense nigro piloso, fortiter punctato, linea dorsali

elevata et tribus utrinque inequalibus instructo, humeris obtuse prominulis, dorso ad medium obtusissime

elevato, apice producto breviter acuto; tegminibus hyalinis, venis brunneo-nigris vel brunneis; pedibus

testaceis, anticis et intermediis elongatis, tarsis fuscis, posticis multo brevioribus; corpore subtus nigro

vel nigro-fusco.

Femina paullo latior, humeris magis prominulis, leviter auriculatis.

A small griseous or cinereous species, variable in size and colour, with black markings on the pronotum, which

are usually very distinct, but occasionally almost absent on the hinder portion; the pronotum is raised in

the middle of the disc, and is somewhat rugose, with a strongly raised dorsal line and three rather irregular

raised lines on each side, and is strongly pilose, especially in front ; humeral prominences variable, small in

male, larger and subauriculate in female, the apex produced into a short and acute beak ; tegmina hyaline,

with the veins brown or yellowish, and with indistinct dark markings across the middle, sometimes almost

absent or only visible near the costa; legs testaceous, the anterior and intermediate pairs long, with the

tarsi elongate and fuscous, the posterior pair very short, with extremely short testaceous tarsi; underside

of the body black or fuscous, the anal segment of the male with a large yellow spot on each side, and the

side sternal pieces more or less yellow in both sexes.

oribus, margine costali preecipue ad basin punctato, maculis nigris distinctis; pedibus testaceis, posticis

brevissimis.

A very small, short species, with the pronotum of a bright ferruginous colour, with two large fuscous markings

on the metopidium extending from the front margin to just behind the humeral prominences, which are

short and blunt; on the dorsal surface there is a whitish band before the apex, followed by a dark one

covering the whole of the apex, except the extreme tip, which is whitish; the punctuation is rather strong,

and there is a strongly raised dorsal line and two or three more or less irregular raised lines on each side

of this ; tegmina with the veins fuscous, lighter towards the base, with large distinct dark markings across

the middle and on the costa between these and the base, the costal margin punctured, especially towards

the base ; legs and underside testaceous, posterior legs very short. —

Long. 34, cum tegm. 5 millim.; lat. 3 millim.

Hab. Panama, Volcan de Chiriqui 2000 feet (Champion).

One male specimen. This is a very distinct little species; the hind legs in the

whole family are shorter than the others, but in this and in H. désparipes this charac-

teristic appears to be especially marked.

The subgenus Enchotype, Stal, does not appear to be represented in our collection;

it resembles Hoplophora in having a comparatively narrow head and three apical cells

to the wings, but in several other points it appears rather to resemble Potnia, Stal.

PLATYCOTIS.

Platycotis, Stal, Kongl. Sv. Vet.-Ak. Handl. Band viii. 1, p. 36 (1869).

This genus is here considered as including the subgenera Lophopelta, Stal, and

Microschema, Stal; they all three differ from Hoplophora in the much broader head

and in the fact that the pronotum is not subparallel behind the shoulders, and shield-

shaped, but is narrowed from the base; the differences inter se, however, are mostly

comparative, and as far as the dorsal horn is concerned in certain species of Lophopelta,

as well as of Platycotis, it is in part or entirely wanting. It may be well, perhaps, to

add Stal’s description of the subgenera (/. c. supra, p. 37, nota) :—

There are two specimens from Mexico in the Vienna Museum under the name of

Umbonia ornata. It is quite plain from Fairmaire’s description and figure! that this

insect is his H. tuberculata, which he describes as from California. H. ornata, described

as from Mexico, is most probably a variety of the same species, and I have, though

with some doubt, as I have not seen the irsect, regarded it as synonymous with his

H. tuberculata. The dorsal horn of P. tuberculata is very variable, being either longer

than its breadth at the base, and extended considerably forward, or very short and not

porrect, or altogether wanting and represented by a blunt prominence. Our fig. 2 is

taken from an example from Jalapa.

8. Platycotis discreta, sp. n.. (Tab. IV. figg. 4, 4 a, b.)

Of an ashy-ochraceous or ashy colour ; head very broad, with the hind margins and a central transverse line

black; pronotum strongly punctured, not rugose, with black markings above the head and between the

shoulders, which are only slightly produced; in the type these black markings consist of a line on each

side of the dorsal line, which they touch between the shoulders, and two black points on each side of these ;

shoulders black ; on the back there is a very blunt, scarcely raised tubercle, surrounded by a black circle,

more or less distinctly marked, and there is a small patch of black on each side, touching the margins, at

some distance before the apex; dorsal line strongly raised, black in front and at the apex ; tegmina hyaline,

with the veins fuscous, in part brown, indistinctly variegated with greenish and brownish markings, with

the clavus and costal margin strongly punctured; underside and legs testaceous, the latter spotted with black.

All the specimens yet discovered are females. The dorsal horn in this species varies

considerably, as in P. tuberculata. Among some unnamed Membracide from the

Stockholm Museum I found a specimen of a Platycotis similar to those in our collection

from the various localities mentioned above, and I therefore described them as a new

species ; but they agreed so closely with the description of P. histrionica that I asked

Dr. Aurivillius to compare his specimen with the unique type of that species in the

Stockholm Museum, and he tells me that P. histrionica only differs from the insect in

question in having the dorsal horn nearly twice as long, and the pronotum reaching

the apex of the abdomen and more tapering at the end. I have therefore suppressed

my species, and included it under P. histrionica; had I not very carefully compared it

with Stal’s description I should certainly have felt justified in treating it as new from

the fact of its having been sent out as unknown from the Stockholm Museum, which ©

contained the unique type of P. histrionica. We figure a specimen from San Gerénimo. |

5. Platycotis nigro-rufa.

Hab. Mexico! (Mus. Brit.), Xucumanatlan in Guerrero 7000 feet (H. HH. Smith) ;

This insect, which Walker described as a Hemiptycha, although it has nothing in

common with that genus, is a very distinct Platycotis of a brick-red colour variegated

with black. It is of about the same size as the preceding species. The two examples

in our collection are mostly griseous, and may belong to another species, though they

do not appear to be sufficiently different structurally to be separated.

OCHROPEPLA.

Ochropepla, Stal, Ofv. Vet.-Ak. Frh. xxvi. p. 268 (1869).

This genus contains three or four small species from Central America and the

adjoining regions ; they are mostly of a unicolorous testaceous colour, uccasionally with

dark markings on the head and on the front of the pronotum or on the tegmina; the

pronotum is unarmed and the wings have four apical cells; the upper cell, however, is

occasionally extremely minute; the shoulders are very slightly and bluntly prominent ;

the pronotum is obtriangular in shape, strongly punctured, with a distinct dorsal elevated

line, and more or less distinct raised lines on each side of it.

One female specimen from Chiriqui, which we figure. I have examined the type-

specimen of O. corrosa, which, as St&l remarks, has the tegmina of abnormal length ;

in other points, however, it scarcely appears to differ from O. punctwm, and I have

therefore regarded them as synonymous. Stal remarks of 0. punctum: “Ab O. corrosa

vix differt, nisi magnitudine minore tegminibusque brevioribus.”

2. Ochropepla pallens.

Ochropepla pallens, Stal, Ofv. Vet.-Ak. Foérh. xxvi. p. 268°.

Hab. Mzxico !, Teapa in Tabasco (H. H. Smith).

We have received a male and a female of this insect from Tabasco. Stal says

of this species: “ O. corrose simillima, minor, paullo latior et convexior, processu

-postico thoracis paullo latiore, tegminibus brevioribus, parte sexta apicali pone

abdomen extensi: e Mexico. An distincta?” . O. pallens certainly resembles

O. corrosa very closely, but it isso much smaller that it can hardly be considered as

identical unless intermediate forms are discovered.

Triquetra hebes, Walk. (List of Homopt. Ins. ii. p. 525), closely resembles 0. pallens,

and must, I think, at all events, be referred to this genus.

8. Ochropepla inzgqualis, sp. n. (Tab. IV. figg. 8, 84, 3.)

0. pallent affinis, sed angustior, pronoto inequali, fortiter punctato, utrinque pone humeros sat prominulos,

-apicem notato; tegminibus hyalinis, venis testaceis vel fuscis, nonnunquam fusco-notatis; pedibus tes-

taceis, tarsis anticis et intermediis interdum infuscatis.

Closely allied to O. pallens but narrower, with the pronotum much less even, and appearing sinuate if viewed

from the side, the elevated lines more marked and the humeral prominences more produced, the latter,

if viewed from above, appearing very slightly recurved in some specimens; the colour is variable, being

sometimes unicolorous ochraceous, but there are often two dark spots just above the head and sometimes

others on the disc or towards the apex of the pronotum ; some specimens are brownish or obscure ferru-

ginous; the tegmina are coloured like the pronotum, being sometimes unicolorous, and sometimes marked

with dark patches in the more darkly coloured specimens.

Rather larger and broader than O. inequalis, with the pronotum deep brown, sprinkled with a few minute

yellowish tubercles ; metopidium flat, set at right angles to the rest of the pronotum, which is not

gradually rounded from between the shoulders, as in the preceding species ; central dorsal line very strongly

elevated and distinct, not sinuate if viewed sideways; there are, however, only slight traces of other

dorsal lines; tegmina rather long, hyaline, with the veins brown ; legs brown.

Long. 4, cum tegm. 52 millim.; lat. inter cornua 33 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

This species, if viewed from above, bears a superficial resemblance to 0. inequalis,

but may easily be distinguished by the characters above mentioned; the outer apical

cell of the wings, however, is considerably larger than in the other specimens of

Ochropepla which I have examined, and the tegmina are somewhat differently shaped,

and their areas therefore somewhat dissimilar. JI am not sure that it may not have to

be referred to another genus. °

POTNIA.

Potnia, Stal, Berl. ent. Zeitschr. x. p. 388 (1866).

The members of this genus may bé distinguished by having the pronotum armed with

a porrect horn in front and the wings with four apical cells; the humeral prominences

are blunt, but distinct. The species in size and shape rather closely resemble certain of

the broader forms of Aconophora, from which they may at once be separated by the

very short posterior tarsi, which are the distinguishing characteristic of the Hoplo-

phorinee.

is distinguished by the wings having three instead of four apical cells); afterwards,

quoted as the type of the genus Enchotype was really H. fairmairei and not H. grana-

densis at all. I have the insects before me, and they so closely resemble each other

that they might well be confused by anyone who had to go by a description in either

case. The genus Enchotype is not represented in our collection. The two specimens in

Signoret’s collection are from Bogota.

The specimen of Potnia granadensis above referred to as from Costa Rica has the

Elongate and proportionally narrow, with the head broad, as broad as the base of the pronotum; pronotum

armed with a long porrect blunt horn, which extends straight forward and forms an unbroken line-

with the dorsum from the apex—if anything it extends very slightly downward from the shoulders; viewed

from above the pronotum is diamond-shaped, the front portion of the diamond being rather shorter than

the hinder portion; the shoulders are moderately prominent and turned downwards if viewed from the

front; the tegmina are very long, extending far beyond the apex of the pronotum, which just reaches.

beyond the apex of the abdomen, and they have five apical areas and one discoidal; the wings are broad

and have three apical areas only and no discoidal; the hind legs and tarsi are proportionally longer than

in most of the other members of the group.

ORTHOPLOPHORA.—ACONOPHOROIDES. AT

‘The insect on which I have formed this genus bears a close resemblance at first sight

to the figure of Umbonia indicator, Fairm. [Ann. Soc. Ent. Fr. sér. 2, iv. p. 279, t. 6.

fig. 14 (in error for 15)], but the apex of the pronotum in the figure extends to the

apex of the tegmina, and for this reason Fairmaire, certainly with considerable doubt,

places it in Umbonia ; the shoulders, moreover, in Fairmaire’s insect are scarcely at all

produced. |

The genus above described is distinguished from Potnia by the quite horizontal, or,

if anything, slightly deflexed horn, and the fact that the wings have four apical cells,

and from Enchotype by its broader head (in which it resembles Platycotis), and, as in

Potnia, by the formation of the horn; the general facies, moreover, is quite different

from that of either genus.

raised patches, and there are dark markings on the metopidium ; the horn of the pronotum is unicolorous,

slightly reddish at the apex, and from its base start two broad black bands, which reach for about two-thirds

of the distance between the humeral prominences (which are black externally and reddish beneath) and

the apex of the pronotum; the margins are reddish and the reddish colour is continued in two bands on

each side between the shoulders and the black bands before mentioned ; these reddish bands almost meet

just above the head; the tegmina are hyaline, with black veins, ochraceous at the base, and with the

subcostal areas yellowish-red; the wings are infuscate at the apex, and the legs are testaceous, with the

This genus is formed to receive A, gladiator, Walk. (=Thelia gladiator, Walk.), and

one or two allied species, which have been classed under Aconophora, but are much more

closely related. to Potnia and Hoplophora: in fact, the genus must be removed to the

Hoplophorine. In form the genus resembles large broad specimens of Aconophora, but

may be easily distinguished by the very small posterior tarsi (the intermediate and

pronotum, and also by the sides of the pronotal horn being furnished with three or

more caring, more or less perfect; in Aconophora the posterior tarsi, although not

always as long as the intermediate and anterior pairs, are never minute, the pronotum

is never carinate, except for the dorsal keel, and the sides of the pronotal horn have one

more or less broad elevated line running from the base to the apex. In the venation

of the tegmina the genus appears to be closely related to Aconophora.

Aconophoroides in general appearance appears to be most closely connected with

Enchotype, St&l, as represented by Enchotype (Potnia) fairmairei, Guér., but it is

distinguished from that genus by the wings having four apical cells instead of three,

and by the plainly carinate sides and horn of the pronotum; in Potnia the formation

of the pronotal horn is quite different. .

altogether.

Subfam. DARNINA.

The genera comprised in this subfamily are somewhat heterogeneous, and several of

them differ very much in general facies; in distinguishing them some writers have

made use of one or two characters which are often misleading, especially that of the

relative distance of the ocelli from the eye and from one another: in certain groups,

e. g. of the Centrotine, it is a very valuable character, for in the Centrotine various.

genera have the ocelli situated almost on the margins of the eye, but in the Darmine

the relative difference of distance is very seldom great enough to be noticeable. The

general character of the venation is most important, but Stél appears to be not quite

right in all cases as to the relative number of the discoidal areas; I have therefore in

the following table made as little use as possible of the latter character, and have

entirely omitted the characters drawn from the ocelli; in nearly all the genera the

areas of the tegmina are more or less elongate, oblong, and parallel-sided, and in. no

case are any of the apical areas petiolate.

p. 29 (1860).

The type-forms of this genus are very peculiar insects on account of their broad form,

scabrous appearance, and the very large and distinct impressions on their surface.

According to Stal, the tegmina have only one discoidal area, but in the first species

described below two are present, and the character is evidently variable. | ‘

‘In our collection there are specimens of three species, one of which belongs to the

typical form, and the second is intermediate and passes on to the third, which any one

would describe as a new genus without the least hesitation, were it not for the second;

after considerable doubt I have come to the conclusion that it is best to class them

together under Aspona until more is known regarding the group, which seems to be a

very scarce one. Tragopa aspera, of Walker’s Cat. Homopt. Ins., Suppl. p. 151, is a

small Aspona, allied to A. bullata, Stal. The genus is allied to Hygris. |

‘Intermediate between Leptosticta and Hebetica, having the form of the latter, and

the general venation of the tegmina as in the former, except that the relation of the

discoidal areas to one another in size and shape is variable.

HEBETICOIDES. 53°

‘On examining two’ specimens which I had without doubt assigned to Hebetica, I

found that they had three veins starting from the base of the corium as in Leptosticta.

I afterwards found a third specimen among some undescribed Membracide from the

Stockholm Museum which presented much the same characteristics of venation; as

Stal forms his genera chiefly on this character, the only alternative appears to be either

to include them under Leptosticta or place them in a new genus. If facies is to be

regarded at all they cannot be separated far from Hebetica, and cannot well be associated

with Leptosticta; I have therefore adopted the latter alternative, though with some

reserve, for although the veining of the corium as regards the two or three veins, as

the case may be, which start from the base seems constant, yet it must be admitted

that there is considerable variation in other points: the discoidal areas, for’ instance,

are sometimes of different relative sizes, and through the absence of _a transverse vein

one only may te present where there ought normally to be two; the tegmina of the

same insect, moreover, are often different in slight points. At the same time, in the

absence of more definite characters, the venation is very valuable as a means of distinc-

tion; and St&l’s genera cannot be set aside, at all events in the present state of our

knowledge and without the examination of much more material than we at present

possess. It may be well perhaps here to quote the characters } assigned by Stal to

Hebetica and Leptosticta respectively as regards venation :—

“ Corio venis longitudinalibus duabus, ven4 ulnari paullo ante medium, vend radiali in medio vel pone medium

corii furcatis, area discoidali exteriori minutissim4, interiore magna elongata; capite thoraceque puberulis ;

Subg. Leptosticta, Stal (type D. flaviceps, Burm.).”

Leptosticta flaviceps bears a superficial resemblance to Darnis lateralis. In the

Vienna Museum there is an insect of Signoret’s labelled “limbata” from Mexico.

Darnis limbata is quoted by Butler (Cist. Ent. ii. p. 341) as a synonym of L. flaviceps ;

but it is evident, on examination of the tegmina, that the insect here referred to is

Stictopelta affinis.

1. Hebeticoides acutus, sp. n. (Tab. IV. figg. 17, 17 a—-d, 3 .)

Latior, nigro-purpureus ; capite metopidioque supra frontem flavis, limboque laterali pronoti virescenti-flavo

plus minusve indistincto; ocellis approximatis; pronoto humeris a fronte viso deorsum prominulis,

dilutioribus ; pedibus flavo-testaceis; abdomine plerumque nigro, marginibus segmentorum flavis.

A rather large species, broad in front and narrowed to a very sharp point behind, of a purplish-black colour,

with the head and the part just above it yellow, and the pronotum with a broad greenish-yellow margin,

extending from behind the shoulders to some little distance before the apex; punctuation, except of the

head and metopidium, distinct and comparatively strong; tegmina of a purplish-fuscous colour, browner

and more transparent towards their inner border ; legs clear testaceous-yellow, with the upperside of

_ the femora only dark ; margins of the segments of the abdomen yellow.

Long. 13 millim.; lat. int. hum. 7 millim.

Hab. Guaremata, Panima in Vera Paz (Champion).

One male specimen. This species is very like Darnis convoluta, but may be easily

distinguished by its broader form and more prominent shoulders, which are differently

shaped, as well as by its glabrous surface and rather stronger punctuation.

2. Hebeticoides confusus, sp.n. (Tab. IV. figg. 18, 18 a, b, 3.)

Precedenti affinis, sed multo minor, humeris minus prominentibus; capite pronotoque brunneo, metopidio-:

nigro, lateribus ad marginem dilutioribus, pronoto vitta laterali nulla, distincte densius punctato; teg--

minibus brunneis, intus hyalinis ; pedibus brunneo-testaceis.

Much smaller than the preceding, with the shoulders less prominent and more closely punctured, and with

scattered hairs towards the apex of the pronotum ; the head and pronotum are brown, and the metopidium

black, the colours being indistinct; the sides are lighter, but there is no marked lateral band; tegmina

brown, internally hyaline; legs testaceous-brown, with the upper part of the femora dark; margins

of the segments of the abdomen yellow.

Long. 9 millim.; lat. int. hum. 44 millim.

Hab. Panama, Volcan de Chiriqui 4000 feet (Champion).

One male specimen. This species has the minute external discoidal area referred to.

by Stal as a character of Hebetica, and in this respect differs from the preceding species ;

but it has the three veins proceeding from the base, and the tegmina so far exposed

beyond the pronotum that two apical areas are uncovered.

3. Hebeticoides denticulatus, sp. n.

Elongatus sat latus, dilute testaceus; capite lato, ocellis approximatis, anguste nigro cinctis; metopidio a

latere viso oblique rotundato; pronoto sat fortiter punctato, lineé media dorsali levi, humeris vix promi-

nulis, lateribus sensim ad apicem angustatis, apice extremo acuto, nigro, vix reflexo; tegminibus hyalinis,

venis exterioribus testaceis, interioribus brunneis ; pedibus testaceis, femoribus subtus ct tibiis distincte

nigro-denticulatis ; pectore nigro, abdomine plerumque testaceo.

A long and moderately broad species, with the sides more parallel and more gradually rounded to the apex than

in either of the two preceding species; head broad, eyes large; pronotum with the shoulders scarcely at

all prominent, rather strongly punctured, dull, with a smooth central line, gradually narrowed to the

apex, which is acute and very slightly reflexed; tegmina hyaline, reaching very slightly beyond the apex,.

with the interior veins darker than the exterior, with two discoidal areas, the exterior being the longer,

and the interior the broader; rather more than one-third of the tegmina is exposed beyond the sides

of the pronotum ; legs testaceous, with the femora and tibize furnished with little black teeth set in rows ;.

underside black, with the abdomen mostly testaceous,

Long. 113 millim. ; lat. 43 millim.

Hab. Mxxico (Boucard, in Mus. Holm.).

- The strong denticulation of the legs, especially of the femora, will serve to

distinguish this species, which may perhaps form the type of a separate genus.

Cryptoptera, Stal, loc. cit. p. 32.

This genus, as here constituted, contains upwards of twenty species from Central or

Tropical South America. I feel, however, very doubtful as regards several of these, for

they run in many cases into one another, and it will be necessary to examine a much

larger amount of material than is at present available before the constitution of the

genus can be finally settled; the venation of the tegmina is very distinct, two veins

only proceeding from the base, and being forked near the middle at about equal

distances from the base. I have included the genus Cryptoptera, Stal, under Stictopelta,

as it only appears to differ in its elongate form, and certain species of Stictopelta lead

up to it,

4. Stictopelta zonifera.

Ochrolomia zonifera, Butl. Cist. Ent. ii. p. 339, t. 7. fig. 2°.

Hab. Mexico! (Boucard, in Mus. Holm.).

The Stockholm Museum specimen is dark violaceous-brown, with light testaceous

markings; the type in the British Museum is of a light testaceous-brown colour, with

lighter markings, and looks quite different at first sight ; on close examination, however,

I can find no structural difference, and I have since found that the variation of colour is

not uncommon in certain violaceous-brown species. The species is not represented in

our collection.

Butler places this species under Ochrolomia, but the venation is that of Stictopelta,

and besides this only a very small portion of the tegmina is visible below the pronotum,.

whereas Stal’s chief character for the genus is that half the tegmina are exposed

(v. Hem. Fabr. ii. p. 32).

5. Stictopelta varians, sp. n. (Tab. V. figg. 1, 1 ac.)

Brevis, latior; capite, marginibus nigris exceptis, testaceo ; pronoto violaceo-brunneo, colore nigro cincto,.

limbo laterali lato albido, subtiliter punctato; metopidio margine extremo testaceo, humeris obtuse

prominulis; tegminibus ultra apicem pronoti extensis, semi-intectis, tegminibus hyalinis ad apicem

brunneis ; pedibus testaceis, plus minusve nigro-notatis.

Var. Ochracea vel testacea, limbis lateralibus albidis supra distinctius nigro cinctis.

Short and rather broad, with the head, except the margins, testaceous; pronotum of a violaceous-brown colour,,

with the part thus coloured surrounded by a more or less broad dark line, which is often not distinctly

marked, on each side at the margins there is a broad elongate whitish band or lateral patch extending

from behind the shoulders and ceasing at some little distance before the apex; the metopidium has the

extreme margin testaceous above the head; the pronotum is finely punctured, and is obtuse at the apex,.

and the tegmina extend beyond the apex, and have at least half their area exposed towards the tips, this

character, however, being variable in different specimens; legs testaceous, more or less marked with black.

Var. Ochraceous or light testaceous brown, with the whitish side patches banded above by a distinct dark.

Hab. Mexico, Ventanas in Durango 2000 feet (Morrer), Jalisco (Schumann).

Two males of the type-form, and one male and three females of the variety, from

Ventanas; and one specimen, without abdomen, from Jalisco.

The variety, at first sight, looks very distinct ; it may possibly be an immature form,

but the markings are very plain. We figure a typical example from Ventanas.

STICTOPELTA. | 57

6. Stictopelta punctata, sp.n. (Tab. V. figg. 2, 2a, d.)

Preecedenti affinis, sed paullo major; capite testaceo, pronoto violaceo-brunneo, metopidio sparsim testaceo,

limbo albido irregulari ab oculis usque ad tertiam partem ante apicem extenso, et macula albida laterali

utrinque prope apicem instructo; pronoto fortius regulariter punctato, haud rugoso, apice obtuso ;

tegminibus longius ultra apicem pronoti extensis, ad apicem fuscis ; pedibus plerumque testaceis.

A little larger than the preceding species, with the pronotum of a violaceous-brown colour, the metopidium

being mottled with whitish-testaceous ; just above the head, which is whitish-testaceous, there are two

narrow transverse black bands, which bend at an obtuse angle and join the margin just aboye the eyes ;

there is an irregular whitish patch at each side, extending from the eyes and ceasing at some distance

before the apex, and between this and the apex, which is blunt, there is an irregular lateral whitish spot ;

the chief character of the species, however, is its strong and regular punctuation, which separates it from

all the other members of the genus; the tegmina extend to some distance beyond the apex, and are more

than half exposed towards the tips; legs for the most part of a light testaceous colour.

Long. 8, cum tegm. 9 millim. ; lat. int. hum. 43 millim.

Hab. Mexico, Mescala in Guerrero (H. H. Smith).

One female specimen. This and the preceding species have the tegmina as much

exposed towards the apex as in the species of Darnis, i.sp., and they belong to Stal’s

subgenus Ochrolomia. The venation of the wings is as in Stictopelta.

7. Stictopelta assimilis, sp. n.

S. varianti quoad colorem et staturam simillima, sed pronoto ad apicemaacutiore apicem tegminum tegente,

et tegminibus pronoto fere totis tectis, facillime distinguenda.

In size and colour very closely allied to S. varians, but easily distinguished by having the pronotum more

acute at the apex and entirely covering the apex of the tegmina, and also by the fact that the tegmina

at the sides are almost entirely covered by the pronotum, which is a little more shining and has the

humeral prominences slightly more marked.

Long. 8 millim.; lat. int. hum. 4 millim.

Hab, GuateMata, Duefias (Champion).

Two male specimens; these are extremely like S. varians, but, according to Stal’s

characters, they belong to separate genera.

8. Stictopelta hinnuleus, sp. n.

Major, sat robusta, testaceo-brunnea, limbo albido pronoti ab humeris usque ad apicem extenso; capite

strigoso; pronoto modice punctato, ad apicem acuminatum sensim angustato; tegminibus hyalinis,

venis testaceis, tertia parte intecta ; pedibus testaceis.

Rather a large species, of a clear testaceous or light olivaceous-brown colour, with a narrow whitish border

extending from behind the shoulders to the apex, which is acuminate ; the head is longitudinally strigose,

and the pronotum is distinctly, and in some parts slightly subrugosely, punctured, and extends beyond

the apex of the tegmina, of which about a third part or less is left uncovered; legs testaceous ; underside

rather dark.

Long. 11 millim.; lat. int. hum. 53 millim.

very distinct; at first sight it looks like a brightly-coloured form of a darker insect, but

this is probably not the case. The specimens are not immature.

9. Stictopelta lineifrons, sp.n. (Tab. V. figg. 3, 3a, 4.)

Parva, elongata, griseo-virescens, lineis quibusdam brunneis transversalibus plus minusve interruptis trans

caput metopidiumque ductis, et limbo laterali pronoti ab humeris usque ad apicem albescenti, colore

nonnunquam indistincto; pronoto angustiori, subtiliter punctato, ad apicem sensim acuminato, humeris

obtuse prominulis; tegminibus hyalinis ad basin testaceis, ad apicem fuscis, venis brunneis vel nigro-

brunneis ; pedibus testaceis.

A small narrow species, of a greyish-green colour, with the head and metopidium lighter, often yellowish, with

four or five dark, narrow, transverse, more or less irregular bands, and with the border of the pronotum

from behind the shoulders to the apex whitish or greenish-white ; the colour is sometimes very distinct

and sometimes almost merged in that of the pronotum ; the pronotum is elongate and gradually narrowed

to the apex, finely punctured and very finely alutaceous between the punctures; the tegmina are

hyaline, somewhat fuscous at the apex, with the veins blackish-brown or brown, and the marginal vein

towards the base black; legs testaceous ; segments of the abdomen with the apical half testaceous.

Long. 64-73 millim., lat. int. hum. 34 millim.

Hab. Mexico, Temax in North Yucatan (Gawmer).

Thirteen specimens. This is one of the most distinct species of the genus that I

have seen; the venation of the wings is that of a typical Stictopelta.

haud abrupte acuminato, interdum fere rotundato; corpore subtus et pedibus testaceis. Pracedenti

affinis, sed colore facillime distinguenda.

Very like the preceding, but on an average smaller and easily distinguished by its colour, the front part of the

pronotum being black—the colour being sharply defined and usually reaching for about a third part of the

whole surface from the front of the metopidium ; sometimes the metopidium only is black, and there are

always a few larger or smaller testaceous markings just aboye the head, which, with. all the rest of the

insect, is testaceous.

Long. 64-7 millim. ; lat. int. hum. 4 millim.

Four male specimens. JS. nigrifrons may possibly be a variety of the male of the

preceding species, but I have not noticed any other colour-varieties of the same sort in

the group.

Santarem }.

Our collection contains a larger series of the insect which I refer to this species

than of any other in the group. In size and colour these specimens are very variable,

and might well be described as several separate species, but they run one into another.

Some are of a decided greenish colour, and others clear testaceous, while the colouring

of the legs and the general form differ considerably in specimens from the same locality :

thus, for instance, there are four specimens from Atoyac, Vera Cruz, from which two

and perhaps three species might be formed on differences that appear to have been

considered specific in the group; the whole of the specimens, however, appear to agree

in having the angles at the sides of the prothorax just behind the shoulders very obtuse,

a character which separates them from the two preceding species.

An example from Jalisco is figured.

Stictopelta fraterna, Butl. Cist. Ent. 11. p. 340°.

I believe this to be only a small form of the preceding, and cannot satisfactorily

identify any of the specimens in our collection with it, although several are extremely

near it; they are, however, connected with the larger specimens of S. indeterminata by

intermediate forms. ‘There is one example in the Vienna Museum collection which

appears to belong to it; the chief difference lies in the shoulders being less prominent.

The other characters, especially those of the colour of the legs and apex of prothorax,

are quite untrustworthy, as may be seen by examining the series of 8. indeterminata in

our collection. |

There are four large and rather strongly punctured specimens (12 millim. in length)

in the Vienna collection, which are either 8. indeterminata or very closely allied to it,

and a very small specimen (7 millim. in length) in our series (from Puebla, Mexico),

closely allied to S. fraterna, which may both belong to new species; in the face, how-

ever, of the acknowledged difficulty of this testaceous group of Stictopelta, which is

expressed by the names given to the species by different authors, I prefer not to

multiply species in the present state of our knowledge.

of S. acutula from Chiacam.

N.B.—I have before me Signoret’s type of Darnis prasina (from Venezuela), on which

Fairmaire described the species; it is very like Cryptoptera olivacea, Stal (=Darnis

TROPIDARNIS, gen. nov.

Generibus precedentibus affinis, sed dorso elevato, distincte et acute carinato facillime distinguendus; tegmi-

corio tribus venis e basi emissis et areis discoidalibus duabus, interiore apicem versus dilatato ; pedibus

teretioribus.

Allied to the other genera of the family, but easily distinguished by having the back

of the pronotum raised and acutely keeled; the tegmina scarcely reach the apex of the

pronotum, and have about one-third of their breadth exposed beyond its sides; the base

externally is opaque and strongly punctured ; three veins proceed trom the base of the

corium, and are continued to the apex, as in Darnis, Leptosticta, and Hebeticoides; and

there are two discoidal areas, of which the interior is the longest and is dilated at the

apex, the exterior one starting at the dilated portion and continuing towards the apex ;

the legs are rather slender. In the specimen described there is an oblique depression

on each side of the dorsal keel at about the middle, which meet or almost meet at the

keel and form a very indistinct V-shaped mark.

Of a light greenish colour, with the head and the metopidium just above the. head testaceous; pronotum,

pidium until it almost meets the head; the punctuation is close and very distinct and regular; viewed

from the side the pronotum is rounded in front and then evenly and gradually sloped to the apex, which

just reaches the apex of the tegmina; the extreme lateral margins are testaceous, with a short dark

mark in the centre ; tegmina hyaline, with a broad fuscous band before the external margin ; legs and

underside dark testaceous, with indistinct fuscous markings.

Very like the preceding, but with the keel more acute and the sides more abruptly sloping to the margins,

which are very narrowly light testaceous ; general colour testaceous, but perhaps faded. Viewed from —

~ above the form is narrower, with the shoulders rather more pronounced and the sides more sharply narrowed

to the apex, which is longer and more acute; viewed from the side the centre of the back is more elevated,

and, in consequence, more abruptly sloped to the apex ; the dorsal V-shaped depression is also more distinct ;

the tegmina have the base and apex brown externally; legs and underside testaceous, more or less fuscous.

Handl. Band viii. 1, p. 34; Butler, Cist. Ent. u. p. 346.

This genus contains a considerable number of species which appear to be confined

to Central and Tropical South America; they may be known by having the pronotum

armed with a long projecting horn or porrect process in front, which is very narrow

and acute if viewed from above, but broad and rounded at the apex (which is often more

or less dilated) if viewed from the sides; it is usually more or less elevated and forms

a more or less obtuse angle with the dorsal line of the pronotum, but in some species

is quite level with it; the areas of the tegmina are oblong. In size there is very great

variation in the different species, and the colour also varies to a considerable extent ;

but at present the genus is in a state of inextricable confusion, and in every collection

that I have seen there are different species mixed. together under one name, or the

same species under different names, or a considerable number of species altogether

uridetermined. Stal (/. ¢. supra) gives what professes to be a dichotomous table of

the known species, which he mentions as “ plurimas, difficilimas, inter se simillimas et

secundum descriptiones auctorum haud certe determinandas”; but, in the first place,

he does not mention anything like the number of species then known in his table, and,

in the second place, his descriptions of most of them are meagre in the extreme, so that,

62 HEMIPTERA-HOMOPTERA.

except in one or two cases, they are, if anything, a hindrance rather than a help. At

the same time it is doubtful whether any satisfactory descriptions can be given for the

determination ‘of species, and the synonymic arrangement below adopted after a

careful examination of a very large number of examples cannot be regarded as more

than provisional, for there appears to be no particular distinguishing character that

can be reliably adopted as a basis to work upon. I have endeavoured to find one in

the male characters, but, although there appears to be a slight difference in certain

species, yet it is so very slight, as far as I have seen, and so difficult to work out, that

it is scarcely worth while to consider it. In certain species the males and females

appear to differ considerably in the formation of the pronotal horn, and have hitherto

been described as distinct.

_ Inthe Vienna Museum collection there are four specimens of what apparently is

the larval or pupal state of a species belonging to the A. pallescens group ; it is shaped

like a small Aconophora in the perfect state, but has no tegmina, these being replaced

by a long corneous piece on each side; the head and eyes are large and the latter are

furnished on their inner side with a long thick tapering black seta.

This is a very distinct species, being clothed with yellowish shining pubescence, with

the dorsal line and a broad line on each side of it smooth, which gives the insect a

striped appearance. Mr. Butler (Cist. Ent. ii. p. 847) says of this species: “I think it

very doubtful whether thisis more than a variety of the preceding species” (A. stabilis) ;

but Walker’s type of A. stabilis is very different from the true A. mexicana, which

does not appear to be in the British.Museum collection at all, one or two other species,

which certainly are closely allied to A. stabilis, being made to do duty for it. Through

the kindness of Dr. Aurivillius I have been enabled to examine one of St&l’s types.

We have received a considerable series of A. mexicana from Atoyac. A specimen

from Volcan de Chiriqui is figured.

Braziu?, Bahia (Mus. Vind. Ces.).

Mr. Butler says that his A. spathata is most nearly allied to A. pubescens: the

examples from Guatemala in our collection form a connecting-link between the two

insects, and appear to show that they are really synonymous. ‘The species is a rather

large one, with the pronotal horn narrow and slender in comparison to its size. ‘There

are also four specimens in our collection, from Dos Arroyos, Guerrero (H. H. Smith),

Atoyac, Vera Cruz (Schumann), and Panzos, Vera Paz (Conradt), which I have somewhat

doubtfully referred to this species ; they come too near it to be described as distinct in

the present state of our knowledge of the genus.

5. Aconophora laminata.

Aconophora laminata, Fairm. Ann. Soc. Ent. Fr. sér. 2, iv. p. 294°.

Hab. Mexico (coll. Spinola).

I have taken great pains to identify this species, but have failed to do so; in the

collections I have examined there are no specimens standing under A. /aminata which

answer to Fairmaire’s description, and other species, in some cases more than one, do

duty for it. Fairmaire distinctly says that the horn is slender and the femora black,

the general colour being testaceous-brown, and the total length 12 mm.; the specimens

in Signoret’s collection are evidently not rightly named, and the other specimens I

have examined do not agree with the description. Stél in his table (Kongl. Sv. Vet.-

Ak. Handl. viii. 1, p. 85) describes the insect as ‘‘corpore sordide flavo-testaceo vel

olivaceo-testaceo, capite nigro, apice inter oculos et frontem flavescente limbato,”

64 HEMIPTERA-HOMOPTERA.

which, in the first place, differs from Fairmaire’s description, and, in the second place,

might be applied to several other species.

6. Aconophora nigricornis, sp.n. (Tab. V. figg. 10, 10 a.)

Olivaceo-testacea, pronoto dense et subtiliter punctato, parcius albido-pubescenti, cornu et apice pronoti nigro,

illo lato, sat longo, suberecto, carina dorsali nigro-brunnea; capite nigro plus minusve flavo-limbato ;

tegminibus hyalinis, venis nigro-brunneis ; pedibus totis testaceis.

Of an olivaceous-testaceous colour (testaceous in slightly faded specimens), with the pronotum thickly and

finely punctured, and, when fresh, apparently sparingly clothed with whitish fugitive pubescence, with

the horn broad and porrect and entirely black or black-brown; the apex also of the pronotum: is

black, and the narrow raised dorsal line black-brown ; the head is ‘black with yellow border, or yellow

with the centre black ; the tegmina are hyaline, with the veins dark and with a slight shade of fuscous

in one or two specimens towards the apex ; legs entirely testaceous ; underside partly dark.

Long. 12 millim.; ab humeris ad apicem cornus vix 6 millim.; lat. int. hum. 4-millim.

Hab. Mexico (coll. Signoret, in Mus. Vind. Ces.); GuaTeMaLa, Chiacam, and San

We figure a specimen from San Gerénimo.

7. Aconophora pinguis, sp.n. (Tab. V. figg. 11, 11a.)

Piceo-castanea, pronoto crassiori, subtiliter subrugosius punctato, sparsim pubéscenti, cornu parvo tenui, vix

erecto, dorso leviter rotundato, apice supra viso breviori; tegminibus fuscis, apicem versus hyalinis ;

corpore subtus piceo; pedibus totis ferrugineis vel fusco-testaceis.

Mas: cornu breviori et crassiori. -

Femina: cornu longiori et graciliori.

Of a pitchy-castaneous colour, with the pronotum rather large, slightly raised and rounded on the back, finely

and subrugosely punctured, the punctuation, however, being somewhat variable, and with a small horn,

which is longer and more slender in the female than in the male, but is much smaller in both sexes in

proportion to the size of the insect than is usually the case in the genus; tegmina fuscous, hyaline

towards the apex, sometimes with the anterior third only hyaline; legs entirely ferruginous or fusco-

testaceous ; underside pitchy.

3. Long. 9 millim.; ab humeris ad apicem cornus 3 millim.; lat. int. hum. 3 millim.

Hab. Paxama, Bugaba, Volcan de Chiriqui 2500 to 4000 feet (Champion).

The specimens from the Volcan de Chiriqui are slightly different from the others in

punctuation and in the colour of the tegmina, but all appear to belong to the same

species. A. pinguis appears to be allied to A. tenuicornis from the Amazons Valley.

There is a single female specimen from Temax, Yucatan (Gawmer), in our collection,

which is allied to this species, but differs in one or two points, being more finely punc-

tured, with the central carina of the horn more marked, &c.; it is not quite perfect

and it could not well be described as new on this one example.

A specimen from Bugaba is figured.

Hab. Mexico! (Bilimek; Mus. Vind. Ccs.), Morelia in Michoacan (Ff. D. G.),

Xucumanatlan and Omilteme in Guerrero 7000 to 8000 feet (H. H. Smith).

Walker's type is a male; the female is very different, being larger, with the pronotal

horn longer and more slender. The specimen in the British Museum, named

A. gilvipes, which was wrongly identified by Walker with A. pugnax, must apparently

be referred to this species; through the kindness of Dr. Aurivillius I have been enabled

to examine one of Stal’s typical A. gilvipes, which is quite different, and belongs rather

to the A. pallescens group.. The male of 4. compressa is a very short stumpy-looking

insect.

The specimens from Morelia, above referred to, are a male and a female, and they

are smaller, lighter, and more pubescent than the ordinary form of A. compressa, but

can hardly be regarded as distinct.

9. Aconophora laticornis.

Aconophora laticornis, Walk. List of Homopt. Ins., Suppl. p. 134°.

4000 feet, Totonicapam 8500 to 10,500 feet (Champion).

Walker's type of A. laticornis is apparently a male ; at all events our specimens come

so close to it that they cannot be described as distinct. The female, however, is a

very different insect, having the pronotal horn very long (nearly as long in some cases

as the distance between the base of the horn and the apex of the pronotum) and in

some cases almost straight ; in one specimen the total length is 15 millim.; the horn,

moreover, in the female, is comparatively slender, so that the name becomes a misnomer

except for the male, in which it is short and broad, although in one or two specimens

it is longer and intermediate in formation between the normal horn of the male and

that of the female. The dark colour, shape of the horn, and the dark horizontal band

on the tegmina will distinguish the species, of which there is a considerable series of

both males and females, from Omilteme, in our collection.

T have carefully examined the types of the above-named insects and have thought it

best to regard them as belonging to one species, although future writers may be of a

different opinion. I can, however, see no point on which to separate them, as in a

large series they lead one into the other, and, in fact, some specimens, except for colour,

very closely resemble females of A. laticornis. The males appear in all cases to have

short pronotal horns and must be referred to A. concolor, Walk., whereas the females

have long horns and must be referred to A. marginata and A. stabilis. Walker’s type

of A. stabilis.is broken and scarcely recognizable, but, so far as can be judged, it is not

different from his A. marginata. |

A considerable : series of males and females have been received from Guatemala city.

This is a rather large variety of A. marginata, of a greenish-olivaceous colour, with

the pubescence more marked in some specimens; it is, however, connected by inter-

mediate forms with the type-form, and cannot be regarded as more than a variety.

11. Aconophora nitida, sp. n. (Tab. V. figg. 12, 12 a.)

Brevior, pronoto nigro vel nigro-piceo, nitido, densius sat fortiter punctato, spatio inter humeros sat lato,

sparsissime flavo-pubescenti, cornu brevissimo ; tegmenibus pubescentibus, fere totis nigris, apice exteriori

late hyalino; pedibus ferrugineis, femoribus interdum ad partem piceis.

A rather short species, broad between the shoulders, which are prominent, with the pronotum black or pitchy-

black, clothed sparingly with golden pubesceuce, which is also present on the tegmina, except towards

the apex; the horn is extremely short, and not broad at the apex; the tegmina.are pitchy-black, with

a small patch on the costa and the interior third hyaline, the veins on the hyaline portion being testa-

ceous; the clavus, moreover, is more or less testaceous; legs ferruginous or reddish-testaceous, with

the femora sometimes partly pitehy.

Long. 8-9 millim. ; ab humeris ad apicem cornus 32 millim.; lat. int. hum. 34 millim.

Hab. PanaMa, Bugaba, Volcan de Chiriqui 2500 to 4000 feet (Champion).

This species is closely allied to A. hadina, Butl., from Brazil, but has the pronotal

horn less produced, and is more shiny and less closely punctured.

We figure a specimen from Bugaba.

It is also closely allied to A. pugionata, Germ., from which it differs in much the

‘same points as from A. hadina ; in fact, if the specimen of A. pugionata sent me from

the Stockholm Museum is correctly named, I believe that 4. hadina and A. pugionata

are identical, especially as both insects come from Brazil.

ACONOPHORA. . 67

Walker erroneously assigned the insect described by Butler as A. hadina to A. in-

cumbens, which is a very peculiar and distinct species, with the rostrum very strongly

and abruptly deflexed; it has been separated by Stal to form his genus Argante.

12. Aconophora variipennis, sp. n. (Tab. V. figg. 13, 13 a.)

Brevior, pronoto piceo, sat lato, subtilius punctato, aureo-pubescenti, cornu brevi erecto, humeris prominulis,

apice longo curvato ; tegminibus variegatis flavo-testaceis, margine costali et maculis quibusdam brunneis

vel piceis, tertié’ parte interiori hvalin&; corpore subtus ferrugineo; pedibus fere totis flavo-testaceis,

femoribus partim fuscis.

Rather short and broad, moderately shining, finely but not very closely punctured, with golden pubescence,

. which is thick on the metopidium ; pronotal horn very short and not broad, considerably erect, front of

horn, metopidium, and head forming a straight line at an angle of about 60°; tegmina yellowish-

testaceous, with the costal margin broadly pitchy, and with other dark markings, the centre of the disc

being of an opaque testaceous colour ; the interior third part is testaceous hyaline; legs almost entirely

light yellow-testaceous, with all the femora more or less infuscate.

Long. cum tegm. 84 millim.; ab humeris ad apicem cornus 3 millim. ; lat. int. hum. 3 millim.

Hab. Mexico, Temax in North Yucatan (Gaumer).

- One female specimen. This species is allied to A. nitida, but is very distinct in

colour, shape, and punctuation. From A. hadina it may be known by the shape of the

pronotal horn, punctuation, &c.

One female specimen from Mexico in the Vienna Museum. ‘This is a very distinct

species, being about as broad between the shoulders as its length from the base of

the horn to the apex of the pronotum; the horn is very short and somewhat porrect,

and there is a very large and deep impression on either side at the margins, Just

behind the shoulders it resembles a Potnia rather than an Aconophora.

14. Aconophora nigra.

Aconophora nigra, Stal, Kongl. Vet.-Ak. Handl. Band viii. 1, p. 35°.

Hab. Mexico (Sallé, in Mus. Holm.).

This is one of the smallest species of Aconophora. Mr. Butler, in his catalogue of

the genus (Cist. Ent. ii. p. 349), gives A. nigra as synonymous with A. concolor, Walk. ;

but the type of the latter species disagrees with Stal’s description, and is very different

from a specimen sent me by Dr. Aurivillius, which he says agrees with Stal’s type of

A, nigra, except that the horn is wanting. Stal’s ‘description of the species is very

meagre :—‘‘ Corpore nigro, thorace in ferrugineum’ obsolete vergente ; ‘tibiis fusco-

ferrugineis; tegminibus concoloribus, apicem versus fuscis; ceteris ut in A. hastata.”

A somewhat long species, comparatively broad at the shoulders, which are prominent; head infuscate, with

the margins more or less distinctly lighter; ocelli distant from one another; pronotum testaceous, with

strong and distinct punctuation, and with a long black horn, which is slender at the base and plainly dilated

at the apex; apex of the pronotum, if viewed from above, rather short and blunt; tegmina dark, with

the apical portion fusco-testaceous, more or less hyaline, and with a testaceous spot more or less indistinct

in the middle, sometimes, however, they are entirely fusco-testaceous with darker markings ; legs entirely

ferruginous, or with the femora partly infuscate ; abdomen more or less dark.

The peculiar shape of the horn and the contrast in colour between the pronotum

and tegmina will easily distinguish this insect. The specimens in the Vienna Museum

collection are larger than the others, and may possibly belong to a different species.

A specimen from the Volcan de Chiriqui is figured.

Hab. Mexico!, Oaxaca (Sallé ?).—-Pzrv 2.

Butler gives 4. hastata, Stal, as a synonym of A. lati¢ornis, which is an entirely

different insect. Dr. Aurivillius has sent me a typical specimen of Stal’s species, which

is identical with 4. prunitia. A. hastata (Fabr.) is allied to A. lata, and perhaps is

identical with A. nigrivitta, Walk.; as there appear to be two species bearing tiie

name of A. hastata, Butler’s name must be retained.

In Signoret’s collection there are two specimens labelled A. hastata, Stal, one of

which appears to be Walker’s A. concolor, and the other is allied to A. pinguis. In

our collection there is a specimen from Omilteme, Guerrero, which either belongs to

A. prunitia, or is very closely allied to it; the horn, however, is straight and level

with the back of the pronotum, whereas in A. prunitia it forms an obtuse angle with

it; the insect may belong to a new species, but is too close to A. prunitia to be

described as distinct on one example.

A Mexican specimen is figured.

shaped pronotal horn. The specimen in Signoret’s collection named A. nigru must be

referred to A. ferruginea. |

Allied to A. fusiformis, but considerably smaller, and with the pronotum.much duller and more thickly and

less strongly punctured ; the horn is extremely short, and the disc is not raised and rounded. There are

two specimens in our collection, a male and a female; the male is piceous, with the horn shorter than in

the female, and with the tegmina dark, except at the apex of the costa and the interior third; the

female is testaceous, with the head and tip of the horn dark, and the tegmina brownish, with testaceous

veins ; in both sexes the underside is piceous and the legs are fusco-testaceous, with the femora, the apex

of the tibiae, and the tarsi more or less fuscous.

Somewhat elongate, of a light ferruginous colour, with the pronotum thickly and finely punctured and

sparingly pubescent; the horn is large and long, in proportion to the body, about as long as the rest

of the pronotum, and somewhat stout, more or less erect; the shoulders are rather prominent and .the

apex blunt ; tegmina light, hyaline, with the veins testaceous, and the base above and below testaceous and

punctured ; there are also two darker spots before and behind the middle, which are sometimes indistinct ;

underside ferruginous; legs entirely of a light testaceous colour, with the anterior and intermediate tibie

more dilated than is usually the case. .

Three female examples. This species in general appearance, if viewed from above,

is most like A. femoralis, but if viewed from the side the difference is at once apparent ;

it is, moreover, larger and broader, with the pronotal horn much larger and longer.

Two of our specimens have the horn strongly erect, but in the third it is rather shorter

and stouter and more depressed.

Closely allied to A. pailescens, but easily distinguished by its considerably greater breadth and by the shape

of the horn, which is short and almost deflexed ; the tegmina are hyaline, with the veins fuscous or

testaceous, and the legs are entirely light testaceous ; the underside is infuscate ; the type specimen is

greenish, the colour being especially marked in front, and in life the general colour is probably darkish

green; the head is infuscate, with.a testaceous border; the tegmina are greenish-hyaline, with the veins

Hab. Mexico, Orizaba (Bilimek, in Mus. Vind. Ces.).

Four male specimens of this species are contained in the Vienna Museum collection ;

in all probability the horn is longer in the female.

A. obtusiuscula is allied to A. pallescens and A. femoralis, but may be known by its

short broad form and the shape of the pronotal horn, and by the abrupt cessation or

diminution of the strongly marked dark dorsal ridge before the middle of the disc of

the pronotum.

27. Aconophora minuta, sp. n.

Minima, capite nigro antice utrinque testaceo, pronoto ferrugineo, subtiliter punctato, cornu modico haud

erecto, humeris prominulis; tegminibus fere totis hyalinis, venis brunneis ; ; corpore subtus infuscato ;

pedibus totis testaceis, vel femoribus plus minusve infuscatis.

A very small species, with the head black, testaceous on each side in front; pronotum ferruginous, finely

punctured, with the horn rather short, forming almost a straight line with the back of the pronotum,

tegmina hyaline ; underside black or pitchy; legs entirely testaceous, or with the femora more or less

infuscate.

Long. cum tegm. 5} millim.; ab humeris ad apicem cornus 2 millim. ; lat. int. hum. vix 2 millim.

Hab. Mexico (Bilimek, in Mus. Vind. Ces.).

Two specimens. The very small size of this species will easily distinguish it.

Amongst the described Aconophore, it comes, perhaps, nearest to A. femoralis.

ALCMEONE.

Alcmeone, Stal, Ofv. Kongl. Vet.-Ak. Forh. xxiv. p. 558 (1867) ; xxvi. p- 256 (1869).

This is one of the most distinct of the genera formed by Stal out of the old genus

Hemiptycha, Germar. It contains six or seven species from Brazil, Cayenne, or Central

America; they are easily distinguished by the very broad pronotum, which is suddenly

narrowed at the apex into a long aculeate process.

1. Alemeone godmani, sp.n. (Tab. V. figg. 24, 24 a, 0.)

Lata, robusta, nitida, sat fortiter parcius punctata, nigra; capite, metopidio ad summan partem, lateribus

pronoti et dorso ante apicem coccineis; vitta laté a margine laterum sub humeris ad cornua (modica et

aculeata, nigra ; tegminibus fuscis: corpore pedibusque testaceis vel fusco-testaceis.

ALCMEONE.—HYPHINOE. 73

A broad and robust species. Head scarlet; pronotum shining black, with the greater part of the front, the

sides, and a space before the apical process scarlet; a narrow scarlet line also runs down the centre of

the black portion ; on each side beneath the horns there is a broad black band reaching to the margins,

and on each side behind the middle there is a round black spot, the top of which is merged in the dark

colour of the dorsum ; apical process very long, straight, aculeate, black; tegmina fuscous, darker towards

the base, sparingly punctured ; legs testaceous, the coxee darker.

Long. cum processu pronoti 15 millim. ; lat. int. corn. 10 millim.

Hab. Mexico, Jalisco (Schumann).

One male specimen. This is one of the most conspicuous insects among the

Membracide in our collection.

HYPHINOE.

Hyphinoé, Stal, Ofv. Kongl. Vet.-Ak. Férh. xxiv. p. 558 (1867), xxvi. p. 257 (1869).

This genus seems to be chiefly distinguished by the different conformation of the

pronotum in the sexes; this has led to a considerable amount of confusion, as the

older authors described the sexes of the same insect as different species. Occasionally

there appears to be a tendency to dimorphism in the male.

Hyphinoé contains about a dozen species, which seem to be entirely confined to

Central America and the immediately adjoining regions. The other genera formed by

Stal out of Hemiptycha (apart from Hemiptycha proper) are Pyranthe, Proterpia,

Lualthe, and Bubalopa, and more might probably be added, as the species are very

variable. ‘The characters, however, which Stal draws from the relative position of the

ocelli with regard to the eyes, and from the proportional size of the parts of the

tegmina covered by the pronotum or left exposed, are not always satisfactory ; and it is

a question whether he has not already gone too far in his division of the genus as at

present known.

There is only one (male) specimen of this species in our collection; but it is well

represented in the Vienna Museum and the Royal Belgium Museum, and there are

examples in the British Museum. It varies very considerably in colour; the greenish

form is the Hemiptycha viridissima of Walker, which Stal writes as a synonym of

H. camelus. Mr. Butler is of opinion (Cist. Ent. ii. p. 345) that Walker's species ought

to be retained as distinct, but after examining a considerable series of the insect I cannot

agree with him, and, moreover, he appears to have confused the sexes, for he says:—

“We have three examples of each form; and H. viridissima not only differs in size and

colour, being much larger and greener than 4. camelus, but it has considerably longer

tegmina, is far more coarsely punctured, has the front margin of the pronotum bracket-

shaped, the humeral horns prominent, and the posterior process longer.” I have

examined these six specimens carefully and find that, of the three insects named

camelus, two are males and one has the abdomen wanting, whereas the three named

viridissima are females; the specimens of viridissima in Signoret’s collection are also

females, and it may therefore be presumed that that insect must rightly be considered

a variety of the female of camelus.

There is another variety, which seems to be confined to the male, which has the

front and the dark dorsal portions of the pronotum of a deep purplish colour and a

variable dark spot on the upper surface just below the horns, which is wanting in the

type form; the tegmina also are darker than in typical H. camelus. There are four

specimens of this variety, labelled ‘ Bilimek, Mexico, 1871,’ in the Vienna Museum

collection. ‘The difference between the sexes is not nearly as marked in this species as

in the preceding.

There is a good series of this species in our collection. The specimens are very

HYPHINOE. — 75

variable in size (10-15 millim.), and to a certain extent in shape. As a rule, the

pronotum is strongly raised in front and abruptly declivous before the apex; but in

several examples it is only sinuate and almost straight. In the collection of the Vienna

Museum there is a specimen, set on one side apparently as a new species, which belongs

to this variety, and there are several others in our collection, mostly from high alti-

tudes. The shape of the front of the pronotum is also variable ; in a male specimen

from the Volcan de Chiriqui the pronotal horns are much more marked than is usual

in the species, and it might with reason be described as a new species if it were not

considered as one of a series. In Signoret’s collection there is a specimen, separated

apparently on a much slighter difference in the shape of the front of the pronotum,

under the name “ fairmairei.” I cannot, however, find that the description has been

published. There are a considerable number of these unpublished species in collec-

tions, and they cause infinite trouble, as, unless the fact of their not having been

published is mentioned, one cannot be certain that the reference has not been missed,

and much time is wasted in a fruitless search forthe name. Worse than this, however,

is the publication of descriptions without locality ; four out of six species of Alemeone

in the British Museum are so described, and the “ Amer. bor.” or “ Amer. mer.” of

the earlier writers are almost as bad as no locality at all. The difficulty of identifying

the species in Stal’s ‘ Hemiptera Fabriciana’ is greatly increased by the fact that he is

obliged to give ‘“‘ America meridionalis” so often as the sole locality.

4. Hyphinoée marginalis. (H. marginata, Tab. V. figg. 25, 25 a, 6.)

3. Hyphinoé marginalis, Fallou, Rev. d’Ent. ix. p. 353°.

Hab. Guatemata (Sallé +).

M. Fallou’s specimen, from the description, is a male, and the four specimens which

I have seen are also males; one of these is in our collection, and I have received two

from the Belgian Museum ard one from the Stockholm Museum, all undetermined.

It is a very conspicuous species, being entirely of a lighter or darker violaceous-brown

or violaceous colour, with a clearly marked whitish-yellow lateral line on eauh side at

the margins, and the tibie and tarsi testaceous. As M. Fallou’s description is some-

what isolated I append it :—“ Brun violacé. Cuisses de méme couleur, avec les pattes

et les tarses jaunes. Prothorax trés renflé, formant un énorme bourrelet 4 la partie

et longe la suture jusqu’a la tache noire de la pointe. Ces bandes jaunes sont elles-

mémes bordées d’un trait noir. Elytres de méme couleur que le prothorax. Long.

M. Fallou has kindly sent me the type; there isa specimen in the Royal Belgian

Museum exactly agreeing with it, but the other examples are of a uniform dark

violaceous, almost black, colour, and therefore are without the “ trait noir” mentioned

in the description. All the specimens are labelled “‘ Guatemala.”

5. Hyphinoe tau. (Tab. VI. figg. 1, 1a, 0.)

Brevis, pronoto brunneo, sat fortiter punctato, ad latera valde compressa late testaceo, vitta nigro-brunnea ab

humeris usque ad cornua extens&, macula utrinque laterali nigré, dorso ante apicem declivi, processu

apicali longo, nigro; metopidio supra viso ante cornua distincte producto, rotundato; tegminibus

violaceo-brunneis ; pedibus testaceis.

A short and small species, with the pronotum of about the same length, without apical process, as its breadth

between the horns, which are moderately produced ; the colour of the pronotum is brown or violaceous-

brown, with the sides broadly vellow and marked with a round black spot ; viewed from above, the brown

colour forms the shape of a T; there is a broad dark band extending from the shoulders to the horns ;

the back of the pronotum presents a broad blunt ridge, which is ‘gradually declivous before the apical

process, the latter being long and black and strongly ridged above ; tegmina of a violaceous-brown colour ;

legs testaceous, with two or three minute black spots.

_ Long. cum tegm. 9 millim.; lat. int. corn. 6 millim.

Hab. Guatema.a, Volcan de Atitlan 2500 to 3500 feet (Champion).

Two male specimens.

This is a very distinct little species, but, unfortunately, all the specimens in the

collection are males. It is possible that the Atitlan specimens may prove to belong to

a distinct species, as the form of the pronotum is an important point; but in all else

they exactly agree with the type form and cannot well be separated until the females

are discovered.

6. Hyphinoé cornuta. (Tab. VI. figg. 3, 3a, 5.)

Hyphinoé cornuta, Distant, Ent. Monthly Mag. xvi. p. 12°.

Hab. Costa Rica, Irazu 6000 to 7000 feet (Rogers).

In several points this insect agrees with the description and figure of Hemiptycha

punctum, Fairm. (Ann. Soc, Ent. Fr. sér. 2, iv. p. 318, t. 6. fig. 22), from Brazil; but

in the latter species the pronotum is longer and elevated, instead of being slightly curved

downwards at the apex. |

H. cornuta is closely allied to the preceding species, but is smaller, with the back

of the pronotum rather more sinuate, and it may be immediately distinguished by the

broad black band beneath the horns reaching to the humeral margins ; Mr. Distant,

who has himself sent me his type, a female, does not notice this point in his

description.

HYPHINOE. 17

7. Hyphinoé purulensis, sp. n. (Tab. VI. figg. 4, 4a, 6, 2; 5, 5a, 4, 3.)

@. Violaceo-brunnea, pronoto elongato, dorso fere recto, fortiter sat remote punctato, margine anguste flava

ab humeris usque ad apicem nigrum extensd, puncto utrinque sat magno laterali, et altero parvo pone

cornua, nigro, cornibus modicis, subacutis, apicibus nigris; tegminibus violaceo-brunneis, nitidis, fortius

punctatis ; pedibus ferrugineis.

3. Multo minor, metopidio supra viso ante cornua obtuso semicirculariter extenso, laterum maculis majoribus,

et colore dilutiore.

Female elongate, shining, olivaceous or violaceous-brown ; the pronotum elongate, almost straight along the

back, and gradually narrowed into a slender apical process, which is very slightly curved over the tegmina;

the apex and tips of the horns are black, and there is a black spot on each side and another behind the

horns; the lateral margins from the shoulders to the apex are narrowly yellow, the colour being distinctly

marked; the horns are robust, subacute, and directed upwards, with the disc between them broad and

slightly hollowed ; tegmina dark violaceous-brown, strongly punctured, especially towards the base; legs

ferruginous.

Long. 17, cum tegm. 18 millim.; lat. int. corn. Y millim.

Male much smaller, with the frontal portion of the pronotum semicircularly extended beyond the horns, which

are blunt; the yellow margins of the pronotum are broader and the lateral black patches much larger ;

the black patches behind the shoulders are more distinct, and they show a tendency in one or two specimens

to become linear and to join the black tips of the horns ; in neither sex is there a black subhumeral band.

Long. 13, cum tegm. 14 millim. ; lat. int. corn. 7 millim.

Hab. Guatemata, Purula and Sabo in Vera Paz (Champion).

Besides the specimens from these localities, there is a testaceous example from

Senahu, Vera Paz, with a minute lateral black spot on each side of the pronotum, and

no spot behind the shoulders; it has the horns, too, shaped more as in H. cornuta, but

there is no dark subhumeral band. ‘The horns in several of these allied forms appear

to vary occasionally, asin Ceresa, and it is possible that, when more specimens are forth-

coming, some of the described species of Hyphinoé may prove to be not really distinct.

In our collection there is also a small cornute male, from Cerro Zunil, Guatemala

(Champion), which closely resembles H. purwlensis, except that it is of a lighter colour

than the ordinary form, and has no black spot behind the shoulders; at first sight it

looks like a distinct species, but it agrees almost exactly in size and shape with a

dimorphic cornute male of H. asphaltina which has been before referred to. I have,

therefore, though with considerable hesitation, included it as a dimorphic form of the

male of H. purulensis.

8. Hyphinoé vulpecula, sp.n. (Tab. VI. figg. 6, 6 a, b.)

Elongata, brunnea, nitida, cornibus apicem versus et apice ipso pronoti nigris, tegminibus brunneis; pronoto

elongato, leviter subrugoso, sat fortiter remotins punctato; cornibus longioribus, leviter curvatis ad

apicem obtuse rotundatis ; dorso paullo post medium sensim declivi; processu longo usque ad apicem

tegminum extenso ; pedibus testaceis.

Elongate, very shining, of a unicolorous brown colour, with the dorsal ridge almost straight, very slightly

sinuate behind the middle, and prolonged into a narrow process behind, which almost reaches the apex of

the tegmina; tegmina brown or brownish-testaceous, the basal half strongly punctured; legs testaceous.

Underside variable, but darker than the rest of the body.

Long. 16-17 millim.; lat. int. corn. 10 millim.

78 HEMIPTERA-HOMOPTERA.

Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion).”

Two female specimens. This is a very distinct species, and at first sight appears to

belong to Eualthe or Hemiptycha proper; but I believe that it is rightly placed under

Hyphinoé, and that it is nearly related to H. cornuta and H. purulensis.

9. Hyphinoé bigutta. (Tab. VI. figg. 7, 7 a, 3.)

flab. Guatemata (Scherzer!), El Reposo, Pantaleon 1700 feet, Volcan de Atitlan

2500 to 3500 feet (Champion).

All the specimens of this species hitherto discovered are females; it is a stout

testaceous-yellow species, with a minute black spot at the sides of the pronotum

(sometimes absent), and the tips of the horns and the apex of the pronotum black.

H. bigutta has somewhat the facies of a large, stout species of Ceresa. Walker

gives the length wrongly (wings 11 lines); the length “cum tegminibus” is 13 or 15

millim., and the breadth between the horns 8 or9 millim. A specimen from El Reposo

is figured.

10. Hyphinoé ochracea, sp. n. (Tab. VI. figg. 8, 8 a.)

Ochracea, subtus brunnea, vitté lata nigré ab humeris pronoti usque ad apicem cornuum extensé; pronoto

elongato, antice lato, sat fortiter punctato ; metopidio ante cornua (breviora et obtusa) subrotundato, dorso

fere recto in processum leviter curvatum fere apicem tegminum attingentem prolongato ; tegminibus

brunneis ; pedibus testaceis.

A large and robust species, ochraceous, with the underside dark, and with a broad black band extending beneath

the horns to the humeral margins of the pronotum ; the margins from the shoulders to the apex are usually

lighter ochraceous or yellow, but the colour is not well defined; the extreme apex of the horns, which

are short and blunt, and sometimes the extreme apex of the pronotal process, are black; pronotum very

broad in front, subrotundate in front of the horns and convex between the horns; moderately strongly

punctured ; apex of the horns and pronotal process black; the pronotum is somewhat rugose, with large

and not very closely-set punctures; the dorsal ridge is gradually declivous a little behind the middle, and

is continued in a long, sharp, apical process, which reaches to the apex of the tegmina; legs testaceous or

brownish-testaceous. The species may at once be known by the shape of the horns, which are much

longer and more curved than in any other member of the genus, and rather resemble the horns of the

species of the genus Hemiptycha proper.

Long. 15 millim.; lat. int. corn. 73 millim.

Hab. GuatemMaua (Mus. Roy. Belg.; Mus. Holm.).

One specimen in the Stockholm Museum, and two others in the Royal Belgium

Museum at Brussels; the description is taken from these latter.

This species may easily be known by its colour, taken in conjunction with the convex

pronotum ; in shape it resembles a large female of H. cuneata.

Several of the species of the genus above described or noticed differ very much in

facies, but it appears best to assign them all to Hyphinoé rather than to create new

genera for them. Stal appears occasionally to become confused over his own genera;

HYPHINOE.—TOMOGONIA. 79

thus, Mr. Butler (Cist. Ent. ii. p. 345) notices that he has erroneously referred Hemi-

ptycha (Hyphinoé) placida, Germ., to Pyranthe.

ICTARANTHE, gen. nov.

Brevis, robustus, capite fere eque longo ac lato, ocellis inter se paullo magis quam ab oculis distantibus, his

magnis, prominulis ; pronoto dorso late rotundato, convexo, haudquaquam carinato, cornibus modicis sat

reflexis, lateribus ad margines profunde semicirculariter impressis ; tegminibus areis discoidalibus duabus

interiori multo majori.

Short and robust; the head about as long as broad, with the ocelli a little more distant from one another than

from the eyes, which are large and rather prominent; the pronotum has the back broadly rounded and

convex, and the sides deeply impressed in a large semicircle at the margins; the outer of the two

discoidal areas is very much smaller in proportion to the inner than is usual in the allied genera.

This genus is closely related to Pyranthe, Stal, from which it differs in the position

of the ocelli, and the deep and regular impressions of the sides of the pronotum ; from

most of the species of that genus it may at once be known by its convex dorsum, but

Pyranthe flavo-marginata resembles it in this respect.

1. Ictaranthe latifrons, sp.n. (Tab. VI. figg. 9, 9a-c, 2.)

Brevis, sat latus, testaceus, cornibus pronoti apicem versus nigricantibus; capite fere levi, metopidio lato, con-

vexiori, leviter punctato, cornibus modicis infra nigro-carinatis ; pronoto luteo, impressionibus ad margines

dilutioribus, lateribus ipsis pone medium in processum acutum sinuatim contractis, apice nigro; tegmi-

nibus hyalinis, margine exteriori infuscaté; corpore subtus fusco-testaceo; pedibus testaceis.

Entirely testaceous, with the exception of the upper apical portion of the horns above, and a line underneath

reaching to the margins, as well as the apex of the pronotal process, which are black or brownish-black ;

the outer portion, also, of the lateral impressions on the pronotum is whitish-testaceous ; the head is almost

impunctate, and the pronotum is more strongly punctured at the sides than on the disc; the lateral

impressions are very distinct if viewed from above, and give the upper surface the appearance of being

contracted in the middle, as is often the case with Ceresa; tegmina hyaline, with the extreme base dark

and punctured, and the external margins infuscate ; legs testaceous.

Long. cum tegm. 9 millim.; lat. int. corn. 6 millim.

species of Ceresa, and it was sent to me placed among specimens of that genus. —

TOMOGONIA.

Tomogonia, Stal, Ofv. Kongl. Vet.-Ak. Férh. xxvi. p. 258 (1869).

This genus contains two species, one from Guatemala and another from Colombia ;

the former of these is the Smilia vittatipennis of Fairmaire, which superficially

resembles a Ceresa, from which genus it is at once distinguished by the venation of

the tegmina.

I am indebted to Dr. Goding for the identification of this species. I have not had

an opportunity of examining a typical specimen of C. prasina myself; the differences

between the various species seem somewhat obscure, and cannot be made out satis-

factorily from the descriptions. C. prasina externally resembles C. vaginata, Germ.

(campestris, Fairm.), of which there are specimens in the British Museum, but it is less

strongly sculptured. A specimen from Cubilguitz is figured.

NASSUNIA.

Nassunia, Stal, Kongl. Sv. Vet.-Ak. Handl. Band iii. 2, p. 30 (1860).

This genus is closely allied to Smiliorachis, from which it differs in having the

shoulders armed with a sharp spine on each side, thus resembling Ceresa; from the

latter genus, however, it may be at once known by the oblong and parallel apical areas,

and the single small discoidal area of the tegmina.

DYSYNCRITUS.—DARNOIDES. 81

Oblong, subparallel, with the head moderately large; metopidium almost straight, narrowly impressed trans-

versely on each side above the head ; pronotum kite-shaped, with the shoulders distinctly but not strongly

prominent, gradually narrowed behind, very narrow in comparison with the tegmina if viewed from the

sides, the central carina distinct, more or less sinuate, the apex ceasing considerably before the apex of the

tegmina; tegmina large, corium with five apical areas, none of which are stylate, but all more or less

oblong, with the veins thick and more or less curved; there is one discoidal area near the exterior

margin, and the third basal area is so strongly petiolate that it appears like a discoidal area in the centre

of the disc ; corium entirely exposed, with a large vein proceeding from the base and touching its margin

not far from the centre; posterior tarsi longer than the others, posterior tibie with rows of spines on

each side.

This genus evidently belongs to the Darnine, and it appears to be rather closely

telated to Nassunia, from which, however, it is very different as regards facies; in

general appearance it resembles a narrower form of Hypamastris.

1. Dysyncritus intectus, sp.n. (Tab. VI figg. 18, 13 a, 4.)

Sat angustus, brunneus, testaceo albidoque variegatus, capite latitudine variante, testaceo, unicolori, vel

Head unicolorous, testaceous, or mottled with brown; prothorax dark brown, variegated with testaceous and

whitish spots or patches, there being two whitish or brownish-white spots or bands behind the middle

portion, and are very variable in shade of colour; the surface of the pronotum is dull, closely and strongly

punctured ; tegmina hyaline, opaque and punctate towards the base, with the exception of the central

portion ; veins large, partly black and partly testaceous, the outer margin at the apex infuscate; abdomen

testaceous ; legs testaceous, with the tibize and femora more or less infuscate; the dorsum, if viewed from

the side, is variable in sinuation, the front part being more raised 1 in some cases than in others,

DARNOIDES.

Darnoides, Fairmaire, Ann. Soc. Ent.. Fr. sér. 2, iv. p. 495 (1846).

This genus is represented by three or four species from Central or South America ;

with the exception of D. limbata, Fairm., they are small insects, and are more closely allied

to Acutalis than to Darnis, to which, they bear very little resemblance. I believe that

D. brunnea, Germ., and the insect here described probably belong to a separate genus,

but it is better to leave all the species together in the present state of our knowledge.

Apart from the shape and size, the venation of the tegmina is somewhat different, the

strongly-marked discoidal area in D. limbata, the type of the genus, being absent or only

slightly indicated in the smaller species; the general type of the venation, however, is

the same, and the number of discoidal areas seem more variable than in any other

genus I have examined: Fairmaire gives the proper number as one, and Stal (Ofv.

Kongl. Vet.-Ak. Férh. xxiv. p. 559) as two; but in a specimen of D. nigroapica in the

Royal Belgian Museum collection there are three on one tegmen and two on the other,

the central basal area being divided by a well-marked vein at about the middle, this

probably accounting for the discrepancy between Fairmaire and Stal.

1. Darnoides affinis, sp. n. (Tab. VI. figg. 14, 14 a, 6.)

Parvus, flavo-testaceus, apice pronoti pectoreque nigris ; pronoto haud nitido, dense et distincte punctato, a dorso

viso fere sequali, vel antice leviter rotundato-elevato, apice longo acuto; tegminibus fere totis intectis, ad

basin punctatis, hyalinis, venis testaceis, apicem versus brunneis; abdomine pedibusque testaceis, femo-

ribus ad partem nigris. |

Entirely testaceous, or sometimes apparently with a greenish tinge, which is probably more apparent in life,

with the apex of the pronotum and the breast black; pronotum dull, closely and distinctly punctured, if

viewed from the side almost straight, or slightly rounded and elevated in front, the apex produced into a

long acute process, the central line distinct ; tegmina large, almost entirely uncovered, hyaline, with the

veins testaceous, brown towards the apex; abdomen and legs testaceous; ovipositor of female black.

Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith); Guatemata, El Reposo (Cham-

pion); Panama, David in Chiriqui (Champion).

This insect is closely allied to D. brunnea, Fairm. (Smilia brunnea, Germ. Rev. Ent.

Silb. iii. p. 308), from Brazil; the latter, however, appears to be larger and more

shining, but the descriptions given are so meagre that it is difficult to determine it.

The specimens placed under the name D. brunnea in the Royal Belgian Museum have

each of them a narrow black band across the pronotum at the shoulders, and the veins

of the tegmina lighter and less distinct ; but Germar says nothing about the black

band, and the specimens referred to should probably be assigned to a new species.

A specimen from E] Reposo is figured.

SCAPHULA.

Scaphula, Fairmaire, Ann. Soc. Ent. Fr. sér. 2, iv. p. 494 (1846).

The species described below I had originally referred to a new genus near Darnoides,

and described it as the type, but on examining Fairmaire’s figures of the tegmina

(7. ¢. t. 7) I found that his fig. 19 gave a very fair representation of the tegmina of the

species, although it certainly did not in any way (as I had before noticed) represent the

tegmina of Acutalis, to which Fairmaire assigns the illustration in his table (J. ¢.

p. 530) ; on comparing the description it was evident that Fairmaire had made an error

in his numbering of the figures, and that fig. 19 must be referred to Scaphula, and fig. 20

to Acutalis *. The description of the genus given by Fairmaire is very meagre, but I

* As the figures of the tegmina on this plate of Fairmaire’s (op. cit. t. 7) are in a great state of confusion,

as St&l in part has noticed (Kongl. Sv. Vet.-Ak. Handl. Band viii. 1, p. 21, note), it may be as well to correct

them fully, as they are at. present most misleading. Fig. 5 (Tragopa) and fig. 15 (Darnoides) are correct, as

also is fig. 18 (Acutalis) ; the latter figure, however, answers to my genus Micrutalis; fig. 9, assigned by

SCAPHULA.—HETERONOTUS. 83

have little doubt that the species here noticed must be placed under it. As he was

the first person who wrote much on the group, it is hardly to be wondered at if there

is considerable confusion in collections with regard to the right determination of the

insects belonging to it.

1. Scaphula melanocephala, sp. n. (Tab. VI. figg. 15, 15a, 3.)

Brevis, lata, nitida ; capite nigro; pronoto ‘lete castaneo, distincte remotius punctato, humeris obtuse promi-

nulis, a dorso viso leviter rotundato, ad apicem brevissimum et obtusissimum depresso ; tegminibus fere

totis intectis, fusco-testaceis, margine exteriori ad basin nigra, punctatis, apice late dilutiori, venis dis-

tinctis, infuscatis ; abdomine brunneo-testaceo; pedibus testaceis.

A small, short, broad, and shining species, with the head deep black, unicolorous, and the pronotum of a bright

castaneous colour, distinctly and not very closely punctured, more strongly at the sides, where it is im-

pressed ; dorsum, if viewed from the side, slightly rounded, depressed before the apex, which is very

short and obtuse; tegmina extending far beyond the apex of the pronotum, with the clavus exposed,

fusco-testaceous, lighter hyaline for about the apical third, exterior margin black and punctured towards

base, veins distinct ; abdomen brownish-testaceous ; legs testaceous.

This genus contains about a dozén species, which have mostly been described from

Brazil; they are among the most extraordinary forms of the Membracide, and bear a

strong likeness to large species of ants, the resemblance being evidently protective.

The species of the genus Heniconotus, Stal, about a dozen in number, were formerly

included under Heteronotus.

Hab. Mexico 12, Orizaba (Saldé).

Mr. Butler (Cist. Ent. ii. p. 357) has pointed out the confusion that has arisen

between this and the succeeding species; they may at once be~known by the fact

that the strong ventral spine is emitted from the penultimate lobe of the pronotum

in H. quadrinodosus, and from the last lobe (which thus bears three spines) in

_ HH. trinodosus.

Fairmaire to Parmula=Horvola; fig. 11, assigned to Horiola biguttata, belongs to Parmula (Fairmaire does

not refer to the species at all in his descriptions) ; fig. 14, assigned to Horiola gibbula, belongs to a division of

Parmula, which, perhaps, may.form a new genus (Fairmaire himself, in his description, J. c. p. 491, assigns

it to Parmula); tig. 19, assigned to Acutalis, belongs to Scaphula; and fig. 20, assigned to Scaphula, belongs to

Acutalis proper.

The insect which I take to be the male of this species is more darkly coloured than

the female, and has the terminal lobe of the pronotum slightly longer and more oval,

with the two lateral spines at its apex very small. The males seem scarcer than the

females, which latter, without exception, have the longer spines. As the insects agree

closely in all other points, I feel sure that they cannot be regarded as separate species.

I have not, however, seen the distinction of the sexes given by any author.

We figure a male specimen from Atoyac and a female from the Volcan de Chiriqui.

Subfam. TRAGOPINA.

This subfamily contains two genera only, which are distinguished by having the

tegmina externally coriaceous and opaque, with the veins of the coriaceous portion

indistinct and sometimes scarcely distinguishable ; the character of the venation, more-

over, is peculiar. Stal separates the Darnida and Smiliida from his ‘Tragopida as

having all the tegmina membranous ; but this is not the case with several of the genera

which he himself assigns to the two groups (Hem. Afr. p. 83), such as Hntylia, Amas-

tris, and Oxygonia, which have the external portion of the base of the corium opaque,

punctured, and more or less coriaceous. In Parmula, and in one or two other genera,

there are coriaceous patches on the tegmina. Dr. Goding places Parmula under

the Tragopina (Trans. Am. Ent. Soc. xix. p. 253); but it cannot be separated far

from Amastris, and Stal (Hem. Fabr. p. 29) includes it rightly under his subfamily

Smiliuda. | . |

The genera may be distinguished as follows :—

I. Tegmina nearly covered by the pronotum ; lateral border of the tegmina very

broad, occupying about one-third of their surface

II. Tegmina with their external half free; lateral border of the tegmina moderate,

not occupying more than one-eighth of their surface . . . . . . . Horiola, Fairm.

A considerable number of species have been described from Tropical South America

TRAGOPA. 85

as belonging to this genus; they are easily distinguished by the very large margin and

peculiar venation of the tegmina. Stal has divided the genus into four subgenera—

Tragopa, i. sp., Ceratopola, Tropidolomia, and Stilbophora; the differences, however, .

are for the most part rather obscure. |

As far as I can gather, the two species below described are the only members of the

genus that have hitherto been recorded trom Central America.

1. Tragopa insignis, sp. n. (Tab. VI. figg. 18, 18 a.)

Brevis, lata, nitida, convexa; capite subquadrato, antice producto; pronoto subparallelo, sparsim pubescenti,

leviter punctato, punctis quibusdam majoribus interspersis, humeris prominulis, fusco vel fusco-nigro,

vittis irregularibus et apice testaceis, apice subtruncato, dorso a latere viso antice et postice sensim et

eequaliter declivi, ad medium fere recto ; tegminibus hyalinis, parte exteriori fusca; corpore subtus fusco ;

pedibus teretibus, fusco-testaceis.

A large and conspicuous species ; broad, shining, evenly convex; head large, almost subquadrate, produced in

front; pronotum subparallel, sparingly pubescent, finely punctured, with very irregular rows of shallow

and indistinct large punctures, central line very indistinct, shoulders slightly and bluntly prominent,

fuscous or fuscous-black, with irregular bands across the middle, and the apex more or less clearly testa-

ceous (sometimes the testaceous colour prevails, but it is very variable); the dorsum is evenly rounded in

front and behind, and the apex is subtruncate; tegmina hyaline, with the exterior part fuscous ;

underside fuscous ; legs slender, testaceous or fusco-testaceous.

Long. 5-6 millim.; lat. int. hum. 4-5 millim.

Zab. PanaMa, Bugaba (Champion).

A small series. This species appears to belong to the subgenus Stilbophora, Stal,

and to be somewhat closely allied to 7. gilviceps, Stal, to judge by the very meagre

description (Bidrag till Rio Janeiro-Traktens Hem. p. 31).

2. Tragopa bugabensis, sp. n. (Tab. VI. figg. 19, 194, 8.)

brevis, lata, nitida, unicolor, castanea, vel nigro-brunnea, vel nigra; pronoto lato, clypeiformi, levissime remotius

punctato; humeris obtuse et breviter prominulis, apice late rotundato; tegminibus fusco-hyalinis, parte

exteriori fusca ; pedibus testaceis vel fusco-testaceis.

A small, short and broad, shining species, unicolorous, but varying in colour in different specimens, being

castaneous, fuscous-brown, or deep black, with the pronotum broad and shield-shaped, very finely and

rather remotely punctured, with the central line very indistinct, but more marked in some specimens

than in others; shoulders bluntly and shortly prominent, apex broadly rounded ; tegmina fusco-hyaline,

with the exterior margin broadly brown; underside fuscous ; legs testaceous or fusco-testaceous.

Long. 33 millim.; lat. int. hum. 23 millim.

Hab. ‘Panama, Bugaba (Champion).

Several specimens. This species appears to belong to one of the sections of St&l’s

subgenus Tropidolomia. oo

Nota.—In Silbermann’s ‘Revue Entomologique,’ iv. p. 191 (1836), a species is

described by Burmeister under the name Tragopa ephippium, with the locality ‘De

l’Amérique Centrale.” This is evidently an Acutalis or Micrutalis, and probably a

variety of Micrutalis binaria (Fairm.) or M. mesta (Stal).

&6 HEMIPTERA-HOMOPTERA.

HORIOLA.

. Band viii. 1, p. 21. .

This genus is closely allied to Zragopa, from which it differs in having about half

the tegmina free and with much smaller margins. Horiola proper only contains

one or two very variable species; it has, however, been increased by the addition of

species belonging to Micrutalis, such as Horiola discalis, Walk. (List Homopt. Ins.,

Suppl. p. 154), &c.

This species is very variable, but the series from Bugaba appears in great measure

to set at rest the question of synonymy, for the specimens vary very much in colour

and size, and among them are examples which answer to typical specimens of

H. glabrata (picta) as well as of H. arcuata. A specimen from Bugaba is figured.

In the Royal Belgian Museum there is a very fine male specimen of H. picta labelled

“ Florata,” ‘“‘ La Cigale Fleurie de Surinam ” (cf. Stoll, Cigales, t. 16. fig. 89). |

Subfam. SMILIINA.

The Smiliinz may be distinguished from the Darnine by having the third apical cell

of the tegmina stylate or petiolate, with the adjacent cells contiguous to one another.

The shape of the third apical cell is usually subtriangular, but in some instances, as in

Hypamastris, it is semicircular, and the vein forming its stalk bisects the base of the

arc. Stal separates the subfamily from the Tragopine, as already stated, on the ground

that the tegmina are entirely membranous; but this is not correct, as in many species

the external margin towards the base is coriaceous. The subjoined table (pp. 87-90)

will serve roughly to distinguish the genera, but it must be regarded as simply an

aid to their identification, and will probably break down in certain points when fresh

genera and species are discovered, in the same way that I have found Stal’s tables

break down in some cases; in fact I should much prefer to leave the tables out

altogether, if it were not for the fact that, in spite of their necessary imperfections,

they are often of great service to students as “ sign-posts.””

SMILIIN A. 87

It might, perhaps, be of advantage to divide this subfamily into groups, but it would

be hard to define where they begin and end. Dr. Goding (Trans. Am. Ent. Soc. xix.

pp. 253 et seg.) forms four tribes—Cerasini, Polyglyptini, Smiliini, and Telamonini ;

but the Cerasini might, with reason, be further subdivided into three—Cyphoniini,

Cerasini, and Acutalini; and the Polyglyptini lead directly into the Smiliini through a

new genus Polyglyptodes.

I. Tegmina free, with the clavus uncovered, its interior margin touching

the external margin of the posterior process of the pronotum.

+ This contiguous double, or in some cases apparently single, vein, which proceeds from the extreme base and

soon divides, is perhaps best regarded as the ulnar vein in all cases ; the radial vein may then be regarded as

either wanting or present, and this will form the basis of a clear division: the meaning of this will be evident

if the tegmina of Cyphonia and Antianthe (v. p. 89 nota), for example, be compared.

The members of this genus are oblong insects, which vary considerably in colour and

punctuation ; about half a dozen have been described from South America, but none

hitherto from Central America. They may easily be known by the formation of the

tegmina, which are strongly and irregularly variegated, with large veins and very

irregular areas, the area at the extreme apex being small, almost semicircular, and

stylate; the margins are fairly broad, but very much narrower than in Tragopa.

PARMULA. 91:

This species is also very variable in colour, but the colours are much more sombre,

varying from black to brown, with a small oblique, sometimes straight, light stripe on

each side behind the middle, touching, or nearly touching, the margins, and often with

the central portion of the prothorax from the front of the metopidium to the middle, or

sometimes almost to the apex, broadly testaceous, the testaceous colour occasionally

prevailing ; the upper surface is shiny and rather strongly pubescent, and somewhat

variably, but as a rule distinctly, and more or less strongly punctured.

I have had some difficulty in identifying the above, and cannot be sure whether I

am right, as I have not seen types, and Stal’s description of the species (J. ¢. p. 30) is

somewhat misleading. Fairmaire (J. c. supra, t. 7. fig. 10) figures an insect as Horiola

biguttata, which evidently belongs to this or the succeeding species; he does not,

however, notice this insect in the text, but on p. 491 he describes a species as

Parmula bistrigata which evidently fits the figure, and the description corresponds to

the insect here noticed as belonging to P. reticulata, which Stal regards as synonymous

with P. bistrigata. On the same plate Fairmaire figures a species as Holiola (sic)

gibbula which he describes in the text as Parmula gibbula, so that it is almost certain

that he has made a second mistake, and that the names Horiola biguttata and Parmula

bistrigata refer to one and the same species.

versé, haud obliqua, utrinque ad marginem, sepe in dorso confluente ; corpore subtus pedibusque fuscis.

Allied to the preceding, but larger and more elongate and parallel, and much duller, very closely and

subrugosely punctured, and, as a rule, scarcely shining; head rather large, usually very narrowly

margined with white; the margins of the pronotum at the shoulders are also narrowly bordered with

the same colour, and just behind the middle there is a straight white band stretching right across from

side to side, which is sometimes broken, and forms two shorter bands extending from the margins; central

line rather distinct ; underside and legs fuscous.

The examples of this species are much more uniform in colour than those belonging

to P. reticulata, and the size, shape, and sculpture will serve to distinguish them.

black, dull, and very closely, rugosely sculptured, with the head red, very large and

Tragopa, and in facies is certainly a Parmula.

xxiv. p. 553 (1867); Kongl. Sv. Vet.-Ak. Handl. Band viii. 1, p. 25 (1869).

The members of this genus, according to St&l, are characterized by the fact that the

corium has three discoidal areas, and that the apical area is transverse and stylate and

subtruncate at the apex, and that the thorax is moderately elevated, and the dorsum, if

viewed from the side, is rounded, acute, and compressed; this definition, however,

necessitates the removal of several of the species which have been placed under

Amastris to a fresh genus, as below described.

This is a small unicolorous green species, with the tegmina entirely hyaline, with

testaceous veins; the pronotum, if viewed from the side, is almost semicircular.

A. simillima is a closely allied species, but is more or less sinuate and depressed in

front, if viewed sideways, and not nearly so evenly rounded. Stal has left the genus

in considerable confusion, for he characterizes five new species as forming a distinct

group in his synopsis“, without attempting to name or "further characterize them. A

specimen from Atoyac is figured.

HYPAMASTRIS, gen. nov.

Genus precedenti affine, sed dorso depresso haud compresso-carinato, tegminibus plus minusve infuscatis, venis

Allied to Amastris, but with the dorsum depressed and not compresso-carinate, and in some cases almost flat,

and with the tegmina more or less infuscate, and apparently almost coriaceous in parts, with the veins

very thick and coloured as the prothorax ; the areas of the tegmina appear more irregular, and the apical

area is nearly semicircular, and occupies the whole apex of the tegmina, the style bisecting the base of the

segment formed by it.

The species belonging to this genus are al] small, varying from about 3-5 millim. in

length ; they are allied to Aygris, Stal, but in the latter genus the corium has only

two discoidal areas.

HYPAMASTRIS. 93

1. Hypamastris segmentata, sp. n. (Tab. VI. figg. 23, 23 a, 3.)

plus minusve infuscatis, macula infuscaté ad apicem, venis magnis brunneis; corpore subtus et pedibus

testaceis unicoloribus vel ad partem fuscis.

A broad and stout species, with the head and front part of the pronotum testaceous, the latter being dark

behind, the change of colour being often gradual; at each side there is a dark semicircular patch usually

bounded by a whitish arc, and there is usually a whitish vitta or patch before the apex, which is often

obscurely testaceous; the pronotum is very closely and distinctly punctured, and evidently, though

sparsely, pubescent, and is strongly impressed at the sides behind the middle; the tegmina, as well as the

pronotum, vary in colour in different specimens, but are always more or less infuscate, and have an

infuscate patch on the apical margin ; legs and underside testaceous, sometimes partly intuscate.

Long. 4-5 millim. ; lat. int. hum. 2-22 millim.

The colour of this species varies considerably, and some of the lighter specimens are

almost unicolorous, but the darker arc at the side is almost always plainly traceable.

Among the specimens from Teapa there is one variety with the ground-colour greyish,

the dark markings of the pronotum very distinct, the sides of the body black, and the

legs light testaceous. The specimen figured is from Teapa. |

2, Hypamastris minor, sp. n.

Minor, isabellina, minute griseo-marmorata, humeris testaceis; tegminibus hyalinis, fusco maculatis, venis

Considerably smaller than the preceding, of a dark fuscous or fuscous-brown colour, minutely marbled with

greyish-brown, and with a minute obscure whitish spot on the central line behind the middle (sometimes

absent) of the pronotum, and a small inconspicuous whitish band before the apex ; tegmina more or less

broadly infuscate, with the veins thick and dark ; abdomen infuscate; legs testaceous.

very blunt and truncate ; head and the centre of the metopidium whitish, with longitudinal purple

lines; pronotum of a fuscous-purple colour, with the central raised line reddish ; dorsal surface almost

Dr. Goding informs me that this species is very near his Amastris stali, and it may,

perhaps, eventually prove to be a variety of that insect; I have not, however, had an

opportunity of examining the type.

Unicolorous brown, with the head obtusely produced, and the pronotum thickly and rather strongly punctured,

with the shoulders slightly prominent, and the central keel distinct ; dorsum slightly uneven if viewed from

the side; tegmina hyaline, not infuscate at the apex, with the veins and the external margin testaceous-

brown, but with the apex not fuscous ; legs brown, the tarsi, the upper part of the femora, and the apex

of the tibizw more or less fuscous.

This species is allied to Z. segmentata, but is larger, and, apart from other differences,

may be known by the absence of the darker segment of colour at the sides.

Of a black or purplish-black colour, variegated with white; head not so strongly produced as in H. brunnea,

white, with dark punctures and dark markings at the sides; metopidium with dark markings over the

eyes ; the ground-colour of the pronotum is white, the punctuation, which is distinct and rather strong,

being dark; a large dark marking, shaped like an hour-glass, occupies most of the dorsum, behind which

before the apex is a white band, the apex itself being dark; tegmina with the veins fuscous and the

external margin testaceous; legs and underside dark, variegated with white.

Form short and broad, with the shoulders obtusely prominent, and the pronotum shield-shaped, gradually

narrowed to the apex; tegmina with five apical areas, which radiate regularly from the slightly dilated

end of the very narrow central basal area; the latter appears to be sometimes divided, but the point is

not quite apparent; wings with three large apical areas and no discoidal area; legs rather stout, extremely

deeply channelled.

The position of this genus is very doubtful, but it seems to be allied to Horiola,

CLEPSYDRIUS, gen. nov.

Sat brevis, robustus; capite magno, antice quadratim producto, ocellis distinctis, inter se ac ab oculis fere seque

distantibus, his magnis, prominulis; pronoto gibboso, antice ampliato, humeris prominulis impressione

forti longitudinali a metopidio separatis, pone medium fortiter constricto, utrinque fortissime impresso,

lateribus sub impressionibus supra visis subtriangulariter dilatatis, deinde ampliato, lato, globoso, convexo,

apice lato, truncato, trispinoso; tegminibus venis crassis, corio uné vena a basi procedente mox in aream

ovalem extensd, deinde areis discoidalibus tribus irregularibus, apicalibus quinque instructo; alis areis

apicalibus quatuor, secundé stylaté; pedibus posticis preelongis.

Oblong; head large, produced in front, ocelli very distinct, situated on a line drawn through the centre of the

eyes, a very little nearer to each other than to the eyes, which are large and prominent; pronotum convex

and gibbous, very strongly impressed at the sides (if viewed from above it appears wide in front, with

the shoulders obtusely prominent, and is then gradually narrowed above the impression in a straight line

to behind the middle, where it is constricted, and then strongly widened into a convex and globose lobe,

which at its widest is about as broad as the prominent shoulders), the apex truncate, and bearing three

spines, of which the two side ones are slender, short, and slightly deflexed; the central spine is

probably longer, but is broken in the type specimen; on either side of the constricted portion of the

dorsum below the impressed portion there is a broad subtriangular prominence; corium with one vein

proceeding from the base, which is dilated into an oval area at a little distance from the base, and is

followed by three irregular discoidal and five apical areas, the extreme area occupying the whole apex,

and being almost: semicircular, veins incrassate and more or less arcuate; clavus with only the external

vein; wings with four apical arcas, the second plainly stylate ; posterior legs very long.

This genus is extremely difficult to locate; in the formation of the pronotum it is

closely related to Parantonaé, but in the venation of the tegmina it approaches very

nearly to Hypamastris, and it must probably be placed near the latter genus.

Shining black, ocelli and eyes whitish, pronotum closely and very distinctly punctured, with a smooth central

line throughout its length, apical spines testaceous at the base; anterior and intermediate pairs of legs

testaceous, with the base of the tibia and the femora dark, the posterior pair very long, with the femora

and tibize, except a broad ring just before the apex, dark; abdomen dark, with the segments testaceous at

apex ; tegmina reaching considerably beyond the apex of the pronctum, vitreous-hyaline, with the extreme

base, a spot covering a portion of the interior discoidal area, and the thickened veins, black or fuscous;

wings with the veins dark towards the apex, light and scarcely traceable behind.

Long. cum tégm. 43 millim.; lat. int. hum. 2 millim,

Hab. Mexico, La Venta in Guerrero (H. H. Smith).

One male specimen. As above stated, the central spine of the apex of the pronotum

is broken; this is not apparent at first sight, as it looks merely rudimentary, but when

examined under a compound microscope the fracture is evident; the spine is probably

longer than the two lateral spines.

As originally constituted, Cyphonia would now contain a considerable number of

species, chiefly from Brazil or Central America. Stal, however, rightly divides the

genus, but has assigned his new name Poppea to the largest division of it. The genus

Cyphonia, which includes the well-known Cyphonia clavata and certain allied species, is

chiefly distinguished by the presence of two upright intermediate blunt spines on the

back of the pronotum, which are entirely wanting in Poppea. These insects are

amongst the strangest and most abnormal of the Homoptera; in the venation of the

tegmina they are allied to Ceresa, but they have a perfectly distinct facies.

POPPEA.

Poppea, Stal, Ofv. Kongl. Vet.-Ak. Férh. xxiv. p. 551 (1867).

This genus contains about thirty species, chiefly from Brazil or Central America, and

is probably widely distributed throughout the intervening region. It is allied to Ceresa

in the form of the frontal pronotal horns, and in the venation of the tegmina and

wings, but the back of the pronotum is rounded and strongly contracted in the middle

on its upper surface, and from the middle or a little behind the middle starts a long

trifurcate process, the central spine being, as a rule, much longer than the lateral ones * ;

between the pronotal horns and the trifurcate process there are no raised curved spines

as in Cyphonia.

It is very difficult to describe the differences between the species, as they are in most

cases more or less relative, but they will be easily seen by referring to the figures which

have been, in most cases, given; they are evidently scarce insects, as the species are

only represented from several localities by from one to four specimens.

1. Poppea setosa, sp.n. (Tab. VII. figg. 3, 3 a-c.)

Testacea, nigro testaceoque hirta; capite insequali, punctis duobus subter oculos nigris, pronoto a latere viso in

curvata, lateribus duplo longiori, his brevibus, apice excepto, crassis et inflatis; corpore subtus testaceo,

plus minusve infuscato; pedibus dilute testaceis, maculis quibusdam parvis nigricantibus.

Of an ochraceo-testaceous colour, clothed with long sete, partly black and partly testaceous, which are thickest

on the metopidium; the head is uneven, with large ocelli, and the pronotum also is very uneven,

presenting the appearance, if viewed from the side, of two large rounded humps with a deep channel

between; the anterior of these humps is excavate in front, and encloses a raised punctured prominence

between the base of the horns, which are short, almost horizontal (being very slightly bent backwards), and

inflated at the base; the trispinose posterior process has the intermediate spine long and slender (if viewed

from the side rather strongly curved downwards, and then at the extreme apex almost imperceptibly

curved upwards), twice as long as the lateral spines, which are short and very strongly dilated, except for

a short pointed apex; the horns and spines are all lighter before their extreme tips, which are darker,

* In the descriptions the trifurcate process is regarded as including the rather broad crescent-shaped piece

from which the spines proceed ; this piece and the spines are, of course, an integral part of the pronotum.

In all the species I have seen the tegmina have the veins in part dark and in part testaceous.

being usually black.

Hab. Mexico, Teapa in Tabasco (H. H. Smith).

Several specimens. ‘This insect appears to be assigned by some writers to Germar’s

Heteronota hirta (Germ. Rev. Ent. Silb. iii. p. 255), from Brazil; but it is plain from

Germar’s description, which is a very full one and very different from the extremely

meagre description of many of the authors who wrote about the same time, that it

cannot be his insect, which appears to belong to Cyphonia proper: for, after speaking

of the “‘cornua antica,” he says “Spine intermedie, breviuscule, erecte,” whereas in

the present insect there are no such erect spines ; that he does not refer to the posterior

spines is evident, for he describes these in detail just afterwards; there are also other

differences. The insects in the British Museum under Cyphonia hirta belong to

P. setosa.

Among some undescribed Mexican Membracide sent to me by Dr. Aurivillius, from

the Stockholm Museum, is a smaller and more rugose form, which may perhaps belong

to a new species; but it is imperfect, having the intermediate spine of the posterior

process broken.

Since writing the above I have examined a specimen of C. hirta in the Belgian

Museum collection ; it is a true Cyphonia with upright intermediate spines, and quite

distinct from the insect above described. Heteronota braccata, Germ., is also a true

Cyphonia, and not a Poppea.

Preecedenti quoad formam pronoti maxime affinis, sed statura multo majori, metopidio ante cornua longiori,

Allied to the preceding in the form of the pronotum, except that the metopidium is more produced and rounded,

but much larger and more darkly coloured; the horns, too, are shorter in proportion; the pronotum is

brown, with the sides lighter, and with small obscure testaceous spots scattered over the general dark

colour; the horns and spines are also testaceous before the apex, the intermediate spine being almost

entirely testaceous, with an obscure dark band in the middle; the horns are short, inflated at the base,

sharp at the apex, and slightly recurved; metopidium with rather thick light sete, which are more

or less present on the rest of the pronotum; pronotum rather coarsely and remotely punctured, uneven,

deeply channelled in the middle if viewed from the side, posterior trispinose process inflated, with the

intermediate spine moderately long, and the two side ones very short beyond the inflated portion; body

dark, with the apex of the segments testaceous ; legs testaceous, with the apex of the posterior tibie and

a spot before their base, and the upper part of the femora in part, dark.

A rather stout and robust species, with the pronotum black (in immature specimens more or less brown), with

the usual testaceous bands before the apex of the spines of the posterior process; the metopidium projects

distinctly beyond the anterior horns, which are short, stout at the base, and almost horizontal, being only

very slightly recurved; the pronotum is strongly, deeply, and subrugosely punctured, especially at‘ the

sides (if viewed from the side, the back is only sinuate in the middle, and not excavated or deeply

channelled as in the two preceding species); the trispinose posterior process is thick, with the central

spine slender, and the lateral spines short and incrassate, and with only a short slender point at the

apex; the body is dark, with the apex of the segments testaceous ; legs testaceous, with the greater part

of the femora, and the apex and base of the posterior tibie, dark.

Long. 74 millim.; lat. int. corn. 3 millim.

Hab. Guaremata, Cerro Zunil 4000 to 5000 feet (Champion).

The type specimen has the pronotum shining black; in a second specimen from the

same locality, which appears to belong to the same species, it is brown with the horns

and posterior process darker, and the legs lighter.

4, Poppea rectispina.

Cyphonia rectispina, Fairm. Ann. Soc. Ent. Fr. sér, 2, iv. p. 502°.

Hab. Mexico ! (Sallé) ; Guatemata, San Juan in Vera Paz, Cerro Zunil 4000 to 5000

feet (Champion).

This species may easily be known by its large size, the almost glabrous disc of the

pronotum, the uniform dark orange-testaceous colour, and the nearly straight lateral

spines of the posterior process.

There is a broken specimen from Sabo, Vera Paz (Champion), in our collection, which

apparently belongs to a new species, closely allied to P. rectispina, but with the

posterior process quite different; as, however, the pronotal horns are wanting, it cannot

be described.

5. Poppea capricornis, sp. n. (Tab. VII. figg. 6, 64, b.)

Rufa, testaceo-variegata, cornibus pronoti (saltem apicem versus) processuque postico trispinoso nigris vel

nigro-rofis, spinis lateralibus ante apicem late testaceis, spinis intermediis vittis duabus testaceis ;

pronoto cornibus longis recurvis acutis, sed quoad curvationem nonnihil variantibus, parce nigro-setoso,

punctis magnis quibusdam remotioribus precipue ad latera instructo; corpore subtus testaceo ad partem

nigricanti; pedibus pallidis, apice et aliquando vitta ante basin tibiarum obscurioribus.

Rufous, more or less distinctly variegated with testaceous, with the horns of the pronotum, at all events

towards the apex, black; the trispinose process has the lateral spines almost parallel with the inter-

mediate spine—it is black with the lateral spines broadly testaceous before the apex, and the intermediate

spine furnished with two testaceous bands, the hinder one being sometimes indistinct ; the horns of the

pronotum are long and recurved, but vary a little in direction; the pronotum is smooth and shining, with

*12.2

100 HEMIPTERA-HOMOPTERA.

a few large shallow scattered punctures, which are thicker at the sides ; body testaceous, in part black ;

legs pale, with the apex of the tibia and a more or less distinct ring before their apex, sometimes wanting,

brown or blackish.

Long. 7 millim.; lat. int. corn. 4 millim.

Hab. Panama, Bugaba (Champion).

Several specimens.

6. Poppea concinna, sp.n. (Tab. VII. figg. 7, 7 a, 5.)

Pallide testacea, parce nigro-setosa, pronoto fere impunctato, cornibus longioribus recurvis, acutis, nigris, dorso

lineis duabus nigris, plus minusve distinctis, a basi cornuum procedentibus ad medium convergentibus,

processu trispinoso postice anguste nigro, spinis ad basin nigris, deinde testaceis, ad apicem nigris ; corpore

antice nigro, postice testaceo, subtus plus minusve nigro; pedibus pallidis, apice tibiarum tibiisque ad

partem nigris.

Of a very pale testaceous colour, with long black sete, which are sparingly distributed, but thicker on the

metopidium ; pronotum almost smooth, with a few scattered large shallow punctures; horns rather long,

acute, recurved, black ; from their base proceed two dark lines, sometimes indistinct, which converge

towards the middle of the raised part of the pronotum; the trispinose process has the front crescent-

shaped smooth part pale, with the hinder margin black, the black colour spreading down part of the

spines, which, however, are more or less broadly testaceous before the apex, which is black; body black

in front, pale testaceous behind, with part of the underside black; legs pale testaceous, apex of the tibia,

and more or less of the tarsi, black.

Long. 8 millim.; lat. int. corn. 4 millim.

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

In the specimen from the Volcan de Chiriqui, which is the one figured, the lateral

spines of the posterior process of the pronotum are a little straighter and more divergent

than in the example from Bugaba, but the difference is very slight.

7. Poppea affinis, sp.n. (Tab. VII. figg. 8, 8a, 0.)

P. rectispine affinis, sed multo minor, rufa, testaceo-variegata ; cornibus pronoti et processu trispinoso obscurio-

ribus; hujus spinis lateralibus rectis, exstantibus, maxime divergentibus, ad apicem vix recurvatis ;

corpore pedibusque fere totis testaceis.

A small species, of about the same size, colour, and appearance as P. munda, which it resembles in the shape of

the horns; in the formation of the trispinose process of the pronotum, however, it is closely allied to

P. rectispina, having the lateral spines almost straight and very divergent, not curved at the base and

then almost parallel to the intermediate spine as in P. capricornis, &c.; the horns and spines are darker

than the rest of the pronotum, except for the usual testaceous markings before the apex of the latter;

body entirely or almost entirely testaceous; legs pale, with small obscure dark markings at the base of the

tibise and at the apex of the femora.

Long. cum tegm. 6 millim.; lat. int. corn. 3 millim.

Hab. Guatemata, Teleman in Vera Paz (Champion).

One specimen. - This little species is quite distinct from any Poppea I have seen,

although in colour and general appearance it is very like several others, until it is

more closely examined.

POPPEA.—PARANTONAE. 101

8. Poppea munda, sp. n. (Tab. VII. figg. 9, 9 a, 3.)

Minor, rufa, testaceo-variegata, vel fere tota pallida, cornibus processuque trispinoso plus minusve nigricantibus,

vel saltem obscurioribus ; pronoto nitido, punctis remotioribus; cornibus acutis, recurvis, spind intermedia

processus postici elongata acuta, spinis lateralibus multo brevioribus, fortiter recurvis; corpore toto

pallido ; pedibus pallidis, tibiarum basi et femorum apice maculis quibusdam minutis obscuris.

A small species, very like P. affinis in colour and appearance, but with the lateral spines of the posterior

process of the pronotum much curved, and not standing almost straight out as in that insect; the light

bands before the apex of the posterior spines, which appear to be always present, are more obscure in

this species than in some of the others, and in some specimens are almost wanting.

Long. cum tegm. 6 millim.; lat. int. corn. 3 millim.

Hab. Panama, Caldera in Chiriqui 1200 feet (Champion).

9. Poppea reticulata, sp. n.

Precedenti affinis, sed longior, paullo angustior; cornibus pronoti magis recurvatis, et processu trispinoso

spinis lateralibus longioribus angustiusque curvatis ; sculpturaque pronoti leviter reticulata.

Very like the preceding, but narrower and of rather longer form, with the horns of the pronotum more curved,

and the trispinose posterior process narrower in front, with the lateral spines longer and differently curved,

the space between these and the intermediate spines being distinctly narrower, and the spines themselves

being more parallel to the central spine; the sculpture of the pronotum is lightly, but distinctly, reticulate ;

the general colour is pale, with the horns and posterior process dark.

Long. 63 millim. ; lat. int. corn. 3 millim.

Hab. GuatEmata, Panajachel 5000 feet (Champiun).

This species appears to be quite distinct from the preceding, but it must be admitted

that there is a specimen from the Volcan de Chiriqui (Champion) in our collection

which is somewhat intermediate, though it belongs to this species rather than to

P. munda. I am inclined to think that it must be referred to another species,

although, on the other hand, it is possible that all three may be varieties of the

same species.

PARANTONAE, gen. nov.

Genus Antonaé, Stal, affine; capite ineequali, leviter striato, ocellis inter se quam ab oculis minus distantibus,

his prominulis ; pronoti antice angustiori, sine cornibus (parte anteriori in medio angulata, utrinque

impress4), ad medium fortiter constricto, deinde fortissime dilatato, globoso, spina un4 apicali instructo ;

tegminibus ut in Antonaé, Stal, reticulatis, areis apicalibus quinque, discoidalibus tribus.

Head uneven, with two small tubercles, finely striated ; ocelli nearer to each other than to the eyes; pronotum

without horns, strongly constricted, and divided into two distinct parts at the middle, where on each side

there are two small lateral prominences, with the front part much the narrowest, obtusely angled in the

middle, and the hinder part very strongly dilated, transversely globose, slightly elliptical, and terminated

by a single spine; tegmina reticulate as in Antonaé and Ceresa, with five apical and three discoidal areas ;

legs slender.

This is a very strange-looking genus; it is closely related to Antonaé, but may at

once be known by the general shape of the pronotum and the absence of frontal

horns.

102 HEMIPTERA-HOMOPTERA.

1. Parantonaé dipteroides, sp.n. (Tab. VII. figg. 10, 10 a.)

Nigra, nitida, sparsim nigro-pilosa, diffuse punctata, spina posteriori brevi, flava, apice extremo nigro ; tegmin-

ibus testaceo-hyalinis, ad basin late brunneis, opacis; pedibus testaceis, femoribus tibiisque ad basin

nigricantibus.

Head and pronotum black, shining ; pronotum plainly but not thickly pilose, diffusely punctured, with the

apical spine short, yellow, with the extreme apex black ; tegmina testaceo-hyaline, broadly brown at the

base ; legs testaceous, with the femora and the base of the tibize more or less infuscate.

Long. 63, cum tegm. et spina apicali 8 millim.; lat. max. pronoti antice 22 millim. ; id. postice 4} millim.

Hab. Guatemata, Aceytuno 5100 feet (Salvin, in Mus. Brit.).

This extraordinary species has the appearance of a large fly; in structure and colour

it is allied to Antonaé incrassata, but it is very distinct from that species, and I have

not seen any insect like it.

CERESA.

Ceresa, Amyot et Serville, Hist. Nat. des Ins., Hémipt. p. 539 (1843) ; Stal, Ofv. Kongl. Vet.-Ak.

Forh. xxvi. p. 245 (1869). .

The species belonging to this genus appear to be confined to America, and to range

from as far north as Nova Scotia to Monte Video and Buenos Ayres; several have

- been described from the United States, and upwards of a dozen from Brazil. From

thirty to forty species in all appear to have been recorded, some of which are very

distinct, while others can scarcely be regarded as separate, and are very difficult to

distinguish ; several appear to have been described from single specimens on characters

which are obviously variable, if a series is examined.

The species are distinguished by their reticulate tegmina, which are almost entirely

exposed and have five apical and three discoidal areas, and by their general form, as

well as by the elongate styles of the male.

The species may roughly be divided into two groups, in one of which the pronotal

horns are slender and recurved, and in the other they are stouter, and not or scarcely

recurved ; there are, however, certain intermediate forms.

The most abundant member of the genus is Ceresa bubalus (Fabr.), which has a very

wide range in North America, but does not occur further south than the United States ;

it has been recorded by Hellman and Riley as doing injury to potatoes (Am. Nat. xvi.

pp. 822, 823). In Central and South America C. bubalus appears to be replaced by

C. vitulus.

AMERICA °°, Venezuela®, Cayenne 2, Brazil4, Rio Negro ®, Rio Janeiro.

This insect is variable in size and colour, being sometimes bright orange-testaceous

and often greenish ; the shape of the horns, too, is somewhat variable, but they are

always sharp and recurved in the type-form.

Var. minor.

Minor, virescens, capite et metopidio ad partem flavo, carina dorsali cornibusque plus minusve rufis;

cornibus interdum curtis, brevissimis.

Smaller, of a greenish tint, with the head and more or less of the metopidium yellow, and with the dorsal

carina and the horns more or less red, occasionally testaceous.

Long. 54-63 millim.; lat. int. corn. 3-4 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith), Temax in North Yucatan (Gawmer).

A considerable series from Teapa, showing very little variation, and a small series

from Yucatan, with the pronotal horns almost wanting in several specimens.

In the Vienna Museum there are three specimens labelled C. vitulus, which do not

belong to that species, but are apparently small C. testacea ; the description, as given

by Germar, Fairmaire, and others, renders it plain that the real C. vitulus cannot

belong to the C. testacea-group. Germar’s description of Smilia pallens, which he

quotes as identical with Fabricius’s insect, is as follows:—‘ Testacea, stethidio antice

convexo, utrinque in cornu horizontale apice reverso producto, dorso compresso,

margine laterali lineolaque semicirculari albidis.” |

Among the insects in the Vienna Museum labelled ‘Coll. Signoret” are two speci-

mens of a Ceresa from Mexico, labelled * meaicana, det. Stal” (apparently a MSS. name) ;

they are very pale and rather strongly punctured, one having rather long recurved

horns and the other scarcely any horns at all. In our collection there are two speci-

mens which answer almost exactly to these, from Chilpancingo, Guerrero, and Cahabon,

Vera Paz, respectively; both, however, appear to be forms of the var. minor of

C. vitulus, which seems to be an extremely variable insect, and will probably be found

to lead up to other species which have usually been regarded as distinct.

2. Ceresa sallei.

Ceresa salléi, Stal, Stett. ent. Zeit. 1864, p. 70’.

Hab. MExico (coll. Signoret}, in Mus. Vind. Ces.).

This species is like a large C. vitwlus, with the pronotal horns longer and stouter in

proportion; apart from its size, it might be classed with some of the forms of that

_ insect; it has apparently been described on a single specimen.

104 HEMIPTERA-HOMOPTERA.

3. Ceresa nigricornis, sp.n. (Tab. VII. figg. 11, 11 @)

Griseo- vel virescenti-testacea, cornibus et carina dorsali et apice extremo pronoti nigris, et macula fusca

utrinque ante apicalem processum; capite testaceo; pronoto nitido, haud dense punctato, cornibus

acutis, sat longis, vix reflexis; tegminibus pedibusque dilute testaceis.

Allied to C. vitulus, but with the horns rather longer and straighter, and of a black colour, which is continued

below to the margins of the pronotum, and above almost to the highest part of the dorsum, the dorsal

carina and the extreme apex of the pronotum being black ; just at the base of the apical process there is

an indistinct fuscous spot, with a light patch just above it, and there are also some scattered whitish points

on the disc, which are more evident in some specimens than in others; tegmina and legs testaceous.

Long. cum tegm. 8—9 millim. ; lat. int. corn. 5 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith).

Two males and two females.

4, Ceresa nigrovittata, sp.n. (Tab. VII. fige. 12, 12a.)

C. vitulo affinis, sed major, et vitté lata nigra ante apicalem processum pronoti facile distinguenda, hac vitta

supra subtusque macula testaced, et supra quibusdam aliis punctis testaceis instructé; cornibus anticis

acutis modice reflexis; tegminibus cum venis pallide testaceis; venis alarum fuscis; pedibus testaceis.

Allied to C. vitulus, but considerably larger than the average specimens of that species, and easily distinguished

by having a broad black band just before the apical process of the pronotum, bounded above and below

by a testaceous mark, and with a few small testaceous spots above, which are sometimes sprinkled over

the whole dorsal portion ; the tegmina and legs are testaceous; the general colour of the pronotum is

more or less rufo-testaceous, but occasionally it is lighter, and sometimes there is a slight brown tinge.

Long. cum tegm. 9-10 millim. ; lat. int. corn. 5 millim.

Hab. GuaTeMALa, Sabo in Vera Paz (Champion).

Several specimens. This is a very distinct species. I have not seen C. difasciata,

Fairm., which is described as having a black marking at the apex, but that species

appears to be about half the size of C. nigrovittata and to differ in other points.

5. Ceresa uncicornis, sp.n. (Tab. VII. figg. 13, 18a.)

Lete rufescens, pronoto nitido, parce punctato, maculis quibusdam vel vittis testaceis, vitté ante apicalem

processum et apicali processu plerumque plus minusve distincte testaceo, apice extremo nigro; pronoti

cornibus aculeatis, fortiter recurvis, nigris vel nigro-apicatis vel rufis ; tegminibus testaceis, pedibus rufo-

testaceis.

Of a bright rufescent colour, with testaceous streaks and markings, which in some specimens are very apparent

and in others indistinct; there is a light patch just before the apical process, which is for the most part

testaceous, with the extreme tip black ; the light marking round the depressed part at the sides of the

pronotum, which is characteristic of the group, is also more or less distinct ; the chief character, however,

lies in the horns, which are very aculeate and very strongly recurved; the tegmina are testaceous and

very shining, and the legs rufo-testaceous.

Long. cum tegm. 104 millim. ; lat. int. corn. 5 millim.

Hab. Panama, Volcan de Chiriqui 2500 to 6000 feet (Champion).

This species is allied to C. axillaris, Fairm.; at first sight it looks very distinct, but

it leads through an almost entirely rufescent variety into the next species, with which,

except for the form of the horns, it is very closely connected.

CERESA, 105

6. Ceresa variabilis, sp. n.

Griseo-brunnea, vel griseo-testacea, vel rufo-testacea ; pronoto nitido, parcius tenuiter punctato, cornibus modicis,

sat. obtusis, plus minusve recurvis, linea post humeros testaced semicirculari, nonnunquam deficiente,

instructo ; tegminibus cum colore pronoti congruentibus, venis fuscis ; pedibus testaceis.

Very variable, of a greyish-brown, quite dark colour, or greyish-testaceous, or rufo-testaceous; the pronotum

shining, sparingly and shallowly punctured, with the horns, as a rule, rather blunt and but slightly

recurved, but variable; tegmina lighter or darker, according to the colour of the pronotum, but with the

veins in almost every case fuscous,

Long. cum tegm. 8-9 millim. ; lat. int. corn. 4-5 millim.

Hab. Panama, Bugaba, Volcan de Chiriqui 2500 to 4000 feet (Champion).

Var. intermedia.

Multo minor, pronoto interdum fere levi, interdum sat fortiter punctato, colore testaceo vel brunneo-testaceo.

Much smaller than the ordinary form, with the pronotum sometimes almost smooth, and sometimes rather

strongly and closely punctured ; colour brownish-testaceous or testaceous.

Long. cum tegm. 6 millim. ; lat. int. corn. 33 millim.

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

The series which I have placed under this species has caused me more trouble than

any other; it is quite possible that they may all be forms of C. vitudus, while on the

other hand they might be described, if found separately, as half a dozen different

species. The distinctly punctured specimens of the var. intermedia come exceedingly

close to the var. minor of C. vitulus, whereas the larger rufescent forms are very nearly

allied to C. uncicornis, which in facies is an entirely different insect from the last

mentioned. The specimens from Bugaba are allied to C. rufescens, Butl., and the

dark brownish specimens to C. drunnicornis (Germ.), but in either case they differ in

important particulars, and are connected together by intermediate forms; moreover,

they have nearly all been captured in one locality, and, to judge by the setting, at one

particular time, as they are almost the only series in the group that are mounted on

card. It appears therefore to be the best plan, in the present state of our knowledge,

to leave them together, as the multiplication of species which are almost certainly

not distinct has already caused considerable confusion.

106 HEMIPTERA-HOMOPTERA.

There is a large series of this species in our collection; they vary considerably in

size, width between tips of the horns, length and concavity of the metoptdium, &c.,

but I can see no reason for separating them. Besides the names above mentioned as

synonymous, I believe that C. cavicornis, Stal, C. fastidiosa, Fairm., and perhaps

C. alta, Walk., belong to the same species, if the specimens in the British Museum

are correctly named ; these insects, however, have not hitherto been recorded from

Central America. The specimens above referred to as from Temax, Yucatan, are

intermediate between C. alta and the form C. patruelis; C. alta, moreover, which is

described by Walker with no locality, appears to be closely allied to the North-

American C. taurina and C. constans, Walk. I have Signoret’s types before me, on

which Fairmaire described C. testacea, and they vary considerably in the points above

mentioned.

8. Ceresa vacca, sp.n. (Tab. VII. figg. 14, 14a.)

Brunnea, indistincte nigro-maculata; pronoto parum nitido, fortiter dense subrugosius punctato, a latere viso

dorso elevato et rotundato, utrinque, sed magis antice, abrupte declivi, processu apicali fere recto, acuto ;

fronte maxime excavaté ; metopidio linea media testaced a capife usque ad apicem pronoti continuata ;

cornibus magnis, robustis, porrectis, recurvatis; tegminibus subrugosis, hyalinis, testaceo- vel flavo-

maculatis ; pedibus fusco-testaceis.

Of a brown colour, indistinctly marked with black; the pronotum comparatively dull, thickly, strongly, and

in part rugosely punctured (if viewed from the side narrow, but with the highest part strongly elevated

and rounded, and abruptly sloping on both sides, but especially in front), the apical process almost

straight ; forehead very strongly excavate; metopidium with a very narrow testaceous raised line which

extends to the apex of the pronotum; horns very large, robust, porrect if viewed from the front, strongly

recurved ; tegmina with yellowish opaque spots on some of the areas ; legs fusco-testaceous.

Long. cum tegm. 11, cum tegm. et corn. 12 millim.; lat. int. corn. 7 millim.

Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith).

One female specimen. This species appears to be very distinct; there is, however,

one specimen in our collection, and another in the Stockholm Museum, which in some

points resemble it as regards the horns, but they may be abnormal forms of C. testacea,

although they might with reason be described as a separate species. Apart from the

horns, however, the general shape of the pronotum in C. vacca, if viewed from the side,

is different from that of any other Ceresa that I have come across. ‘There is an

ordinary female specimen of C. testacea in the collection from the same locality.

9. Ceresa concinna, sp.n. (Tab. VII. figg. 15, 15 a.)

Viridescenti-testacea, capite metopidioque supra caput flavis, cornibus pronoti, carind dorsali et linea mediali

metopidii lete rufis; corpore toto supra punctis quibusdam dilutioribus asperso; pronoto distincte punc-

tato, impressione laterali semicirculari conspicud; cornibus robustis, haud acutis vel recurvis; abdomine

pedibusque dilute testaceis.

Of a greenish-testaceous colour, with the head and parts just above it orange-yellow, and with the horns of the

pronotum, dorsal carina, and a central line continued from the apex of the dorsal line towards the head

red, the whole being flecked with small light testaceous spots; pronotum distinctly punctured, with the

CERESA.—CENTROGONIA. 107

semicircular lateral impressions very plain ; the horns are robust and not sharp and recurved, but formed

as in the C, testacea-group ; abdomen and legs light testaceous.

Long. cum tegm. 7 millim.; lat. int. corn. 3} millim.

Hab. Mexico (Bilimek, in Mus. Vind. Ces.), Vera Cruz (H. H. Smith).

One female from Vera Cruz, from which our figure is taken, and two males, both old

and faded, in the Vienna Museum. This species, at first sight, resembles C. vitulus,

var. minor, but is easily distinguished by the shape of the horns and the punctuation ;

it belongs to the second group of the genus, with the horns robust and not recurved.

There is a third specimen in the Vienna Museum, also labelled “ Mexico (Bilimek),”

which closely resembles the other two which have been above referred to this species,

but it has the horns a little longer and more porrect, and the forehead more concave;

it appears to bear much the same relation to C. eoncinna that C. cavicornis bears to

C. testacea, and may or may not be distinct.

10. Ceresa puncticeps.

Ceresa puncticeps, Stal, Stett. ent. Zeit. 1864, p. 70°.

Hab. Mexico (coll. Signoret 1, in Mus. Vind. Ces.).

It is impossible to identify this species, either from the description or from the

single example on which it was described, which I have before me. The insect is very

old and quite faded, and has both the horns broken, so that their original length

cannot be ascertained. Stal himself compares it with C. (Stictocephala) uniformis,

and, at first sight, with the horns broken, it superficially resembles specimens of that

insect as they stand in collections; but on a closer examination the difference is

obvious.

CENTROGONIA.

Centrogonia, Stal, Kongl. Sv. Vet.-Ak. Hand]. Band viii. 1, p. 24 (1869).

The members of this genus are very closely allied to Ceresa, from which they appear

to be hardly distinct, although in general appearance they more closely resemble

Nassunia ; the genus was formed by Stal for the reception of Ceresa ciliata, Fairm.,

C. nasuta, Stal, and C. unguicularis. Stal, to the last of which the species below

described appears to be closely related. |

1. Centrogonia elegans, sp. n. (Tab. VII. figg. 16, 16 a.)

process furnished with a broad rufous-brown ring bordered in front with light testaceous ; between this

and the apex of the process, which is dark, there are two narrow rufous-brown bands; metopidium

convex, with long scanty pubescence, strongly punctured, rugose; pronotum distinctly punctured

throughout, but more remotely behind, impressed at the sides, with the humeral horns sharp (if viewed

from the front almost straight, but if viewed from above plainly deflexed), their extreme tips dark; dorsum

STICTOCEPHALA.

Stictocephala, Stal, Kongl. Sv. Vet.-Ak. Handl. Band viii. 1, p. 24 (1869).

St&l separates this genus from Ceresa on the absence of the lateral horns of the

pronotum, and the fact that the pronotum is convex and not keeled in front for a

considerable portion of its length; as a matter of fact, however, neither of these

characters is satisfactory, and the character on which the genus must be separated

lies in the formation of the last abdominal segment of the male, which differs very

much from that of Ceresa, the edeagus being shorter and much widened at the apex,

and the styles being much shorter. .

In the present state of our knowledge it is almost hopeless to distinguish the

members of the genus satisfactorily, for they appear to have been described in several

instances from old and faded specimens, and when a long series is available for

comparison it is evident that examples which evidently belong to the same species

differ considerably in size and breadth &c. Stictocephala appears to be almost, if not

entirely, confined to North and Central America.

Hab. Mexico! 2, Chapultepec and Puebla (Bilimek, in Mus. Vind. Ces.), Guanajuato

This species is the Thelia tacta of Walker (according to his types, though not quite

according to his description), and answers exactly to the description of C. femorata of

Fairmaire. It may be known by its greenish colour (which, however, in many old

specimens is entirely faded to a light testaceous), and especially by the colour of the

underside, which is almost entirely black in the male, the ovipositor only being black

in the female; in the male, moreover, the upper part of the base of the femora is

black, in the female the legs are of a uniform testaceous or greenish-testaceous colour.

One or two of the species that have been described without reference to sex ought very

probably to be referred to this species.

2. Stictocephala dubia, sp. n. °

Testacea vel virescenti-testacea, capite dilutiori; pronoto densius et distinctius punctato, humeris distincte

prominulis, processu apicali, carina dorsali usque ad medium et carinis anticis lateralibus late rufis,

punctis quibusdam albidis, colore nisi in recentibus exemplis multo dilutiori et decolorato, seepe uniformi,

testaceo ; corpore subtus toto testaceo, abdominis disco raro infuscato; pedibus testaceis.

Of a testaceous or greenish-testaceous colour, with the head lighter and the pronotum broadly red along the

dorsal and lateral keels, proceeding in front from the dorsal keel, the red and part of the testaceous colour

in quite fresh specimens being sprinkled with minute whitish spots; the colour, however, is extremely

variable, and the red seems very fugitive; the punctuation of the pronotum varies considerably, but is

usually distinct, and is coarser at the sides; the underside is testaceous, the disc of the abdomen being

rarely dark ; legs testaceous.

Long. cum tegm. 6-63 millim. ; lat. int. hum. 24-3 millim.

Hab. Mexico, Chilpancingo in Guerrero, Cuernavaca in Morelos, Teapa in Tabasco

(H. H. Smith), Atoyac in Vera Cruz (Schumann), Orizaba (H. H. S. & F. D. G.),

Temax in North Yucatan (Gaumer); GuaTEMALA, near the city (Champion).

This species is very variable in colour and in a certain degree in shape, and I have

had to go to a great extent by the localities in keeping the specimens united. It

is quite probable that Ceresa chlorotica and C. uniformis, Fairm., are forms of this

species, but it is impossible to identify them from the descriptions, which are practically

the same in both cases, or from the old uniformly testaceous and evidently faded

examples which stand in the Belgian and Vienna Museum collections under these

names. In the British Museum collection there is the single type of Thelia rufivitta,

Walker (from Florida), which is a Stectocephala and comes very near the most brightly

red-coloured examples of this species, and may perhaps belong to it; the formation,

however, of the shoulders is different.

Var, major.

Virescens, major, distinctius fortiusque punctata.

Much larger than the type, of a greenish or greenish-testaceous colour, with the punctuation stronger.

Long. cum tegm. 8 millim. ; lat. 4 millim.

Hab. Mexico (Sailé), Ciudad in Durango 8100 feet (Forrer), Chilpancingo in

Guerrero 4600 feet (H. H. Smith).

This variety looks exceedingly different from the type-form of the species, but it is

not distinct enough to be separated unless more examples can be discovered, as there

is at least one typical and one or two intermediate forms from the same locality.

3. Stictocephala fusca, sp.n. (Tab. VII. figg. 17, 17 a.)

Fusco-brunnea, capite metopidioque supra caput flavo-testaceis ; pronoto dense et distincte antice subrugosius

punctato, humeris prominulis sed variantibus ; abdomine testaceo ; pedibus dilute testaceis.

Very like some of the forms of the preceding species, somewhat variable in shape, of a fuscous-brown cclour,

sometimes with very small lighter spots on the disc and at the sides of the pronotum, which are more

strongly punctured than the front part, where the punctuation is thick and finer and slightly subrugose ;

110 HEMIPTERA-HOMOPTERA.

the shoulders are slightly prominent, but more so in some specimens than in others; the head and front

part of the metopidium are yellow-testaceous, and occasionally the hinder part of the pronotum is reddish ;

the abdomen is testaceous, and the legs clear testaceous, the colour in some specimens being very light.

Long. cum tegm. 6 millim.; lat. int. hum. 3 millim.

Hab. Mexico, Presidio de Mazatlan (Forrer).

Several specimens. It is quite possible that this may be only a variety of the

preceding species, but the examples are quite fresh and differ considerably in colour

and general appearance from the type specimens of S. dubia.

4, Stictocephala elongata, sp.n. (Tab. VII. figg. 18, 18 a.)

Elongata, angusta, viridescens; pronoto a latere viso minus elevato, supra viso depresso, antice subtilius ad

latera parcius fortiusque punctato, carina dorsali laté obtusa utrinque apicem versus compresso-sulcata,

humeris rotundatis, haud prominulis ; abdomine pedibusque totis testaceis.

Narrow and elongate, with the pronotum greenish, the head and front part of the metopidium being testa-

ceous; pronotum very narrow between the shoulders, which are rounded and not prominent, finely

punctured in front, coarsely at the sides, with the flattened front part before the dorsal carina very long,

the dorsal carina being obtuse and broad and compressed and indistinctly sulcate on each side of the

apical process ; the abdomen and legs are entirely testaceous.

Long. cum tegm. 7 millim.; lat. int. hum. 23 millim.

Hab. Mexico, Ciudad in Durango 8100 feet (forrer).

One female specimen. This is one of the most distinct of all the representatives of

this genus in our collection.

5. Stictocephala cornuta, sp. n.

Testacea, nitida, capite metopidioque supra caput flavis; pronoto dense fortiusque, ad latera parcius, punctato,

humeris in cornua modica sat acuta vix reflexa productis, cariné dorsali et carinis lateralibus ex hac

procedentibus cum cornibus lete rufis, his ad extremum apicem nigris, impressione laterali semicirculari

conspicua, processu apicali acuto toto rufo ; corpore subtus pedibusque flavo-testaceis. |

Of a testaceous colour, with the head and front of the metopidium lighter, and with the dorsal keel and keels

proceeding from this broadly and brightly red, the surface being often flecked with small light spots and

in front with greenish spots or patches; the pronotum is distinctly punctured, more coarsely at the sides,

where the lateral semicircular impression is very distinct, and is produced in front into two moderate

horns, which are stout and very slightly reflexed, and are red, with the extreme tips black; the apical

process is long and acute, red; the underside and legs are entirely of a light testaceous colour.

Long. cum tegm. 7 millim. ; lat. int. hum. 44 millim.

Hab. Panama, Bugaba (Champion).

Two males and one female. This species is like a Ceresa in general appearance, but

the formation of the apical appendages of the male (which are exposed and visible in

the type specimen) shows clearly that it must be referred to Stictocephala.

There are three rather coarsely punctured specimens of a Stictocephala in our

collection (one male and two females), labelled “ Quezaltenango, Guatemala, 7800 feet

(Champion),” which have the underside infuscate in both male and female, and may

perhaps belong to another species, but they are too much faded and discoloured to

identify or describe.

PHACUSA. il

| PHACUSA.

Phacusa, Stal, Stett. ent. Zeit. 1864, p. 72; Ofv. Kongl. Vet.-Ak. Férh. xxvi. p. 247 (1869).

This genus was formed by Stal to inciude one or two species closely allied to

Acutalis, but larger and more elongate than the average representatives of the latter

genus, and chiefly distinguished by the fact that the tegmina have one discoidal area ;

as in Acutalis, the tegmina and the wings have five and four apical areas respectively.

Stal has described two species, and three more are here added, all being from Central

America.

1. Phacusa flavo-marginata. (Tab. VII. figg. 19, 19a.)

Phacusa flavo-marginata, Stal, Stett. ent. Zeit. 1864, p. 72°.

Hab. Mexico (coll. Signoret}, in Mus. Vind. Ces.).

One very imperfect example. This species appears to be a well-marked and distinct

one, and may be easily known by the colour of the pronotum and the black base of

the tegmina. |

2. Phacusa pallescens.

Phacusa pallescens, Stal, Ofy. Kongl. Vet.-Ak. Férh. xxvi. p. 2471.

Hab. Mexico (coll. Signoret!, in Mus. Vind. Ces.).

This is a small pale testaceous species, of about the same size and appearance as a

pale specimen of Acutalis fusco-nervosa, from which it may at once be distinguished

by the neuration of the teg mina.

8. Phacusa major, sp.n. (Tab. VII. figg. 20, 20a.)

Elongata, nitida, unicolor, olivacea vel testacea: P. pallescenti maxime affinis, sed multo major, antice latior,

humerisque magis prominulis.

Much larger and broader than P. pallescens, to which it is closely allied, and with the shoulders more promi-

nent ; the tegmina are entirely hyaline or slightly infuscate towards the apex.

Long. 9 millim.; lat. int. hum. 4 millim. .

Hab. GuatEMALA, Volcan de Agua 8500 to 10,500 feet, San Gerdénimo 3000 feet

(Champion). .

The two specimens from San Gerdénimo are more distinctly punctured and have the

tegmina slightly infuscate towards the apex; they can hardly, however, be regarded as

distinct, and may perhaps be a connecting-link between P. major and P. pallescens.

We figure a specimen from the Volcan de Agua.

4. Phacusa variata, sp. n.

Preecedenti affinis, sed minor, dilute testacea, capite pallido notis quibusdam obscurioribus nonnunquam

112 , HEMIPTERA-HOMOPTERA.

Allied to the preceding, but of a pale testaceous colour, with the head pale, sometimes with darker markings,

and with the pronotum broadly castaneous in front as well as at the apex; sometimes the apex is pale

and there is a dark patch before it; the tegmina are hyaline, with a broad oblique patch at the apex,

which is sometimes very distinct and sometimes only just indicated ; legs rufo-testaceous.

Long. 64 millim.; lat. int. hum. 3 millim.

to 10,000 feet, San Gerdénimo 3000 feet (Champion).

5. Phacusa dubia, sp. n.

Brevior, pronoto testaceo, unicolori, vel antice nigro notato, tegminibus ad marginem fuscatis, venis pleramque

nigris, crassioribus, areéque discoidali minimé; corpore subtus obscuriori; pedibus rufo-testaceis vel

fusco-testaceis.

Rather shorter than the preceding species, with the pronotum unicolorous or marked with a large black spot

in front; the tegmina are infuscate towards the margin, with the veins for the most part thick and black

and with the discoidal area very small; the legs and underside vary somewhat in colour.

Long. 6 millim. ; lat. int. hum. 3 millim.

Hab. Guatemaa, Cerro Zunil 4000 to 5000 feet (Champion); Panama, Volcan de

Chiriqui 4000 to 6000 feet (Champion).

I feel very doubtful with regard to one or two of these species, but with the present

amount of material available it is hard to arrange them differently. St&l appears to

have described P. pallescens and P. flavo-marginata on single specimens, and it is quite

possible that when a large series is examined two or three of the species may be found

to be not really distinct, as the differences appear to a certain degree to resemble those

found in a large series of Acutalis fusconervosa, pale specimens of the latter species

closely resembling P. pallescens, while some of the coloured specimens are very like

P. variata, except that they are smaller. Asa rule, the formation of the single discoidal

area of the tegmina is very distinct, but occasionally it is separated by an abnormal

vein, so that the specimens in which this occurs might almost be referred to Euritea.

6. Phacusa lineola. (Tab. VII. figg. 21, 21a.)

Darnis lineola, Walk. List of Homopt. Ins., Suppl. p. 1467.

Hab. Mexico (Glennie! ; Bilimek,in Mus. Vind.Cws.), Atoyac in Vera Cruz (Schumann).

This species is narrower and more elongate than any of the preceding, and has the

lines on the sides of the pronotum much more strongly impressed; it is, moreover,

more closely and distinctly punctured, and therefore duller. The tegmina are almost

entirely uncovered and are altogether hyaline, except for a distinct oblique dark band

at the apex; the apical petiolate cell of the tegmina is very small; the colour appears

to be green in life, but fades to testaceous in dry specimens. I have not much doubt

in referring the species to Phacusa, although it might perhaps be made the type of a

new genus. A specimen from Atoyac is figured.

EURITEA,—ACUTALIS, 1 13

EURITEA.

Euritea, Stal, Ofv. Kongl. Vet.-Ak. Forh. xxiv. p. 552 (1867).

This genus closely resembles Phacusa, of which it is regarded by Stal as a subgenus ;

it is distinguished by the fact that the tegmina have two discoidal areas.

A very distinct species, of which we figure a specimen from the Volcan de Atitlan.

ACUTALIS.

Acutalis, Fairmaire, Ann. Soc. Ent. Fr. sér, 2, iv. p. 496 (1846) (part.).

As here limited, this genus contains those species which have five apical areas to the

tegmina and no discoidal area; occasionally one of the small areas at the apex of the

internal or external margins is wanting or has the vein ill-defined, but this is very

seldom the case, and the species cannot be confounded with Micrutalis, in which the

veins are less marked, and in the great majority of species very inconspicuous.

Fairmaire mentions Acutalis as having five apical areas, but says that one is often

“ atrophied,” and he gives two figures (op. cit. t. 7. figg. 18 & 20; not 19, as he states

in error on p. 496) which well represent the difference between Acutalis and Micrutalis,

but refers both to Acutalis: throughout the Homoptera certain veins are often wanting

in some examples of one species; but if the difference is constant throughout a whole

species or group of species, those veins can hardly be spoken of as ‘ atrophied.”

Micrutalis balteata forms a connecting-link between the two genera; but if its tegmina

be examined, the differences will be at once apparent, and, with the exception of this

and one or two allied species, the members of the last-named genus are very small

and inconspicuous.

Cotomsral.

This is an extremely variable species as regards colour; the pronotum is either

of a light unicolorous testaceous, in which case the insect superficially bears an

exceedingly close resemblance to Phacusa pallescens, or has a darker patch in front,

which varies from light castaneous to almost. black, and is often broken by lighter

patches; occasionally the pronotum is greenish, with a testaceous patch in front; the

veins of the tegmina also vary in depth of colour. The darkest specimens are very near

A, nigrinervis, but even in extreme examples they may be known by the fact that the

dark colour is always more or less broken or suffused before the apical process, and

that the veins of the tegmina are less marked; at the same time it is possible that

A. nigrinervis may be merely an extreme local variety of this species.

Its variability naturally creates a doubt with regard to species in allied genera, of

which, as yet, only small series are known; probably, as time elapses, several of them

will be classed together, when connecting-links are discovered between them.

Black, shining, with the front part of the head, a band above the forehead, and a band at each side of the pronotum

light yellowish-testaceous, sometimes with a greenish tinge; the two lateral bands touch the margin in

front, and behind merge in the dark colour of the apical process; upper surface thickly and rather

distinctly punctured; tegmina hyaline, with large thick dark veins; abdomen testaceous; underside of

front parts mostly dark; legs testaceous, with the tarsi and sometimes the upper part of the tibiw and

femora more or less infuscate.

The differences between this insect and the preceding have been pointed out above.

The name A. niqrinervis is attached to the insect in the Vienna Museum collection, and

is apparently a manuscript name of Stal’s; he does not, however, appear to have ever

published a description, and this is the case with several other species, and great

confusion is caused thereby. An example from Orizaba is figured.

TRACHYTALIS. 115

TRACHYTALIS, gen. nov.

tribus,

Allied to Micrutalis, from the greater number of species of which genus it may be at once known by the large

central discoidal area of the tegmina, immediately behind which follows a distinct basal area; the chief

distinguishing characters, however, are the long posterior process of the pronotum, which reaches as

far, or nearly as far, as the apex of the tegmina, and the more or less distinct sinuation of the dorsum,

if viewed laterally, as well as the dull fuscous colour, the raised central line of the pronotum, and the close

and strong punctuation, which is also present on the external part, at all events, of the strongly veined

tegmina.

Of a dark dun colour, greyish or brownish, with more or less obscure specks of greyish variegation; head

black; pronotum thickly and distinctly punctured, very slightly, but distinctly, sinuate, if viewed from

the side; the body is yellowish underneath; the tegmina are hyaline, with the margin towards the base

punctured and more or less infuscate, and usually with a distinct elongate fuscous patch at the edge of the

large discoidal area ; legs fuscous or fusco-testaceous.

A considerable series has been received from Chilpancingo. The two specimens in

Signoret’s collection are rather larger, and have the fuscous patch on the tegmina more

marked, but they can hardly be regarded as distinct. We figure an example from

Chilpancingo.

Preecedenti simillima, sed dorso a latere viso ad medium sat profunde sinuato, vittaque ad basin processus

This species may very easily be distinguished from the preceding by its outline, if viewed from the side, there

being a deep sinuation in the middle, which causes the front and hinder part to be raised and rounded ;

the process of the pronotum is also shorter; the general colour is darker, and there is a whitish-testaceous

ring at the base of the pronotal process, the apex of the latter being broadly whitish-testaceous, except at

its extreme tip; the tegmina are more distinctly and irregularly infuscate.

Long. 4 millim.; lat. int. hum. 2 millim.

Hab. Mexico, Cuernavaca in Morelos (H. H. Smith).

‘Two examples. In one or two specimens belonging to the preceding species there

is a tendency to a lighter patch before the apex, but the outline of the dorsum of

T. distinguenda will at once distinguish it.

116 HEMIPTERA-HOMOPTERA.

MICRUTALIS, gen. nov.

Genus Acutali et Trachytali affine, sed ab illo tegminibus areis apicalibus quatuor, forma breviori, et statura

seepissime minima, ab hoc, ut supra memoratum est, distinguendus.

Closely allied to Acutalis, with which it has usually been included, but distinguished by the fact that the

tegmina have only four apical areas; as a rule there is no discoidal area, but occasionally the central

basal area has a vein running across it a little before the base, thus forming two areas; the venation of the

wings is variable, three or two apical areas being present, but no discoidal; the tegmina are either

entirely hyaline, or to a greater or less extent coriaceous and opaque.

This genus presents great difficulties, and perhaps ought not to be separated from

Acutalis in the present state of our knowledge, although I feel sure that eventually it

will have to be even further subdivided. There are apparently two well-marked forms

—one in which the tegmina are entirely hyaline, or with a small dark spot at the extreme

base, and the other in which they are to a greater or less extent coriaceous and opaque ;

in the latter case it is hard to distinguish the veins, even when the tegmina are mounted in

Canada balsam and examined under a compound microscope, as they are of almost the

same consistency as the opaque portion through which they run. In one case (J. binaria)

I have found this difference to be, in part at least, sexual, and it will probably be found

to hold in other species also. In a considerable number of the species with hyaline

elytra the veins are very fine and scarcely traceable, while in others they are thick and

conspicuous and approach the venation of Acutalis. ‘There are only four apical areas

to the tegmina, and, as a rule, no discoidal; in some specimens, however, of these

species with more stoutly veined tegmina, there is a small area cut off from the central

basal area, as above stated, which makes the latter appear divided, with part forming a

discoidal area; the venation, however, in these cases is very different from that of

Trachytalis, which is abundantly distinct by other characters apart from venation.

The species are extremely variable in several cases, and it is impossible without the

actual comparison of the type-specimens (which I have not been able to see in all cases)

to tell what is the correct synonymy; some of them have been described under

Horiola, to which they cannot belong, if the figures of the tegmina given by Fairmaire

(Ann. Soc. Ent. Fr. sér. 2, iv. t. 7), even with Stal’s alterations (Hem Fabr. p. 21, note),

are right; the difficulty is increased by the presence of specimens under MS. names in

Signoret’s collection.

With the exception of M. balteata, the species are very small, and one or two are

among the most minute of the Membracide.

1. Micrutalis balteata.

The specimens in our collection do not quite agree with the ordinary form, being

rather smaller and somewhat differently coloured, but they can hardly be regarded as

belonging to a distinct species ; the colour of the typical form is variable.

The type form described by Fairmaire is very easy to distinguish, for it is, as he says,

“‘partagée en deux parts,” the front part including the basal portion of the tegmina

being black, and the hinder part whitish. Among some specimens of this form,

however, from Chontales, Nicaragua, there is one with the tegmina entirely hyaline,

which proves to be a male, and, as far as I have been able to examine, the difference

is certainly in part sexual: before finding this out I had come to the conclusion that

the coriaceous basal portion of the elytra might form a good character for the sub-

division of the genus, and certainly for dividing species; under the circumstances, however,

I cannot find any real distinction for the following insects which come from much the

same localities, and I therefore provisionally arrange them as a variety of M. binaria.

Var. mutabilis.

Differt a forma typicd tegminibus in utroque sexu totis hyalinis, et colore variabili.

Colour very variable, whitish, with a black patch on the front of the pronotum, or testaceous with darker

entirely hyaline, or at most are a little darker at their extreme base. The length, as in the type form,

varies from 24-3 millim.

In the Belgian Museum collection there are several specimens of a Micrutalis from

“ Guanajuato,” Mexico, labelled Acutalis masta, a species described by Stal from Rio

Janeiro (Kongl. Sv. Vet.-Ak. Handl., Band. ii. Haft. 2, p. 33), They appear to be

identical with the insects here described as M. dinaria, var. mutabilis, and if correctly

named the whole must be referred to A. mesta, Stal, which must be regarded as a

separate species, or sunk as a variety of M. binaria, probably the latter, because of

intermediate forms; I have not, however, seen a type specimen of A. mesta..

To judge from the description, A. variabilis, Berg (Hem. Arg. pp. 244, 302), may be

a rather larger form of the same species.

It must be admitted that the extreme forms of WV. binaria appear entirely different,

but it seems impossible, with a long series before one, to divide it satisfactorily ; it is

probable that the two or three species next described or noticed may also be only

extreme forms of U/. binaria.

As I have already noted, anted, p. 85, M. binariais perhaps not distinct from Zragopa

ephippium, Burm., which I suspect isa Micrutalis.

8. Micrutalis discalis.

Horiola discalis, Walk. List of Homopt. Ins., Suppl. p. 154’.

Hab. Mexico, Vera Cruz (Sallé +).

This is a very pretty little species, yellowish in front, deep black abruptly behind,

and white at the extreme tip. I have not seen another specimen like it, but I am of

opinion that it will very probably prove to be a variety of M. binaria.

4. Micrutalis pallens, sp. n.

Tota pallide testacea, vel capite notis quibusdam fuscis, pectoreque ad partem infuscato, tegminibus totis

hyalinis; pronoto dense subtiliterque punctato ad apicem interdum obscuriori, tegminibus multo breviori ;

pedibus testaceis, tarsis unicoloribus vel partem nigricantibus.

Entirely pale testaceous, or with the head, the chest, the extreme apex of the pronotum (or the sides of the

apical portion), and the tarsi sometimes marked with darker colour; pronotum very thickly and finely

punctured, but in this point somewhat variable ; shoulders rather prominent, if viewed from above; tegmina

and wings clear hyaline.

Long. 3 millim.; lat. 13-2 millim.

Hab. Mexico, Omilteme in Guerrero, Atoyac in Vera Cruz, Teapa in ‘Tabasco

(Hi. H. Smith).

This insect may at once be known by its uniform colour; as far as structure goes it

closely resembles WM. btnaria, and may be only a variety of that species.

5. Micrutalis malleifera, sp. n. (Tab. VIII. figg. 1, 1a.)

Nigra, capite antice albido, ad basin nigro; pronoto antice lato, humeris vix prominulis, dorso a latere viso fere

recto, subtilissime punctato, subalutaceo, nigro, linea angusta supra caput, marginibus humerorum, macula

minuta supra hoc, macula utrinque lata ad marginem pone medium, apiceque ipso, albidis; tegminibus

totis hyalinis, venis indistinctis; abdomine testaceo-albido; pectore abrupte nigro ; pedibus albidis, plus

minusve infuscatis.

A moderate-sized species, with the head whitish in front and black at the base; the pronotum is very finely

punctured and subalutaceous, with the dorsum almost straight, if viewed from the side, black, with the

margins above the head and near the shoulders, and a minute spot near the shoulders, whitish ; behind

the middle there are two white patches at the margins, which constrict the black colour to a narrow band,

and these, with the white apex, form a mallet-shaped large black marking covering nearly the whole

pronotum ; the tegmina are entirely hyaline, with indistinct veins; the abdomen is testaceous-white, the

chest being abruptly black; legs whitish-testaceous, more or less infuscate.

Long. 4 millim.; lat. int. hum. 2 millim.

Hab. Muxico, Orizaba (Bilimek, in Mus. Vind. Ces.; H. H. Smith & F. D. Godman).

The species appears to be very distinct in its extreme form, but there are some

small specimens in the Vienna Museum collection which seem to approach certain

varieties of UM. binaria. |

6. Micrutalis viridicollis, sp.n. (Tab. VIII. figg. 2, 2a.)

Robusta, capite longo, nigro-brunneo, lined longitudinali testacea; oculis prominulis ; pronoto antice lato,

utrinque fortiter impresso, distincte fortius punctato, a latere viso rotundato-elevato, ante apicem brevem

depresso, humeris prominulis, nigro, vitté lata virescenti semicirculari a medio extensé, maculam magnam

MICRUTALIS. 119

obscuram in metopidio includente, apice extremo albido; tegminibus nitidis, parte tertid apicali excepta

nigris, opacis, hac hyalina, venis testaceis distinctis; corpore subtus (lateribus prosterni brunneis nitidis

exceptis) pedibusque totis Jaete flavo-testaceis.

Rather a broad, stout species, with the head dark, with a light central line; pronotum strongly impressed at

the sides, distinctly and not very closely punctured, with a blunt, short, depressed apex; the dorsum, if

viewed from the side, is rather strongly rounded; the colour of the pronotum is black, with a large green

semicircular band extending from the middle to the shoulders and along the sides of the metopidium, and

enclosing on the latter a large dark patch which reaches the front margin, the extreme apex whitish ;

tegmina shining black for almost two-thirds of their length, then abruptly hyaline, the hyaline portion being

furnished with distinct testaceous veins; underside and legs clear yellow-testaceous, the sides of the

prosternum brown, very shining.

Long. 4 millim.; lat. int. hum. 2 millim.

Hab. Panama, Bugaba (Champion).

One female specimen. This is a very distinct species, and differs considerably from

any other which I have seen; the colour may prove to be variable, but the general

shape and structure and veining of the tegmina will serve to distinguish it.

7. Micrutalis notatipennis, sp.n. (Tab. VIII. figg. 3, 3 a.)

Robusta, lata, capite pronotoque totis nigris, hoe distincte remotius, ad latera densius, punctato, dorso a latere

viso leviter sinuato, ante apicem nonnihil sinuato, apice ipso brevi; tegminibus, apice hyalino excepto,

coriaceis, opacis, maculé ad marginem exteriorem, alteraque minori ad marginem exteriorem albida,

notatis ; corpore subtus pedibusque nigris, tibiarum apice testaceo.

A broad, stout, and rather large species, entirely black, except the apex of the tegmina and two spots un the

exterior and interior margins, which are hyaline; the tibiz also have a whitish ring at the apex;

pronotum distinctly and rather remotely punctured, more distinctly and strongly at the sides, the sides

not or scarcely impressed, the shoulders marked by a smooth, rather sharp, callosity, the apex short and

blunt, just reaching to the end of the coriaceous portion of the tegmina; veins ceasing before the hyaline

portion of the tegmina.

Tong. 4 millim.; lat. int. hum. 2} millim.

Hab. Mextco, Chilpancingo in Guerrero 4600 feet (7. H. Smith).

One male specimen. At first sight this species looks more like a small Horiola or

Tragopa; but it belongs to neither of these genera, and it appears best to place it

under Micrutalis, at all events provisionally.

8. Micrutalis dubia, sp. n.

Sat robusta et lata, nigra, nitida, pronoto latera versus obscure flavo-notato, subtilissime punctato, apice ipso

brevi, obtusissimo, albescenti; tegminibus, plus quam tertidé parte apicali excepta, brunneo-variegatis,

parte apicali hyalina, venis magnis brunneis, area apicali secundd minima, brunned, vix conspicua; corpore

subtus nigro ; pedibus brunneis.

Rather broad and short, shining black, with very obscure yellow markings at the sides of the pronotum, and a

. very narrow brownish-white line at the margins of the shoulders; pronotum very finely punctured, the

apex short and blunt, whitish; tegmina with rather more than their apical third hyaline, and the rest

dark, somewhat variegated, the veins large, dark, conspicuous, the area at the extreme apex very minute

and dark; underside black; legs ferruginous-brown.

Long. 3 millim.; lat. int. hum. 2 millim.

Hab. Panama, Volcan de Chiriqui 2500 feet (Champion).

120 HEMIPTERA-HOMOPTERA.

A single female specimen. This species bears a considerable affinity to the preceding,

from which, however, it is very distinct.

9. Micrutalis lugubrina.

Acutalis lugubrina, Stal, Kongl. Sv. Vet.-Ak. Handl., Band. iii. Haft. 2 (Bidr. till R. Jan. Hem.-

Faun. 11.), p. 82 (1860)*.

Hab. Mexico, Teapa in Tabasco (H. H. Smith); Panama, Volcan de Chiriqui 2500 to

4000 feet (Champion).—Brazit, Rio Janeiro |.

This is a small species, rather larger than the type form of WM. (Acutalis) binaria,

of a deep shining black colour, except the apex of the tegmina and abdomen, which are

hyaline; as in M. dinaria the veins are continued further than the dark coriaceous part

of the tegmina, and on this portion are inconspicuous. The specimens in our collection

agree so closely with those from Rio Janeiro in the Belgian Museum (from which locality

Stal described it) that I cannot separate them; there is a slight differeuce in punc-

tuation, but this is a very variable character in many Homoptera. The species stands

in the Vienna Museum collection under the name of “ déipartita” (apparently a MS.

name of Signoret).

Var. parallela.

Forma typicali magis parallela, pronoto fortius punctato, humeris minus prominulis, ad medium distinctius

impresso, et interdum macula flava vel albid& pone medium instructo.

More parallel than the type form and more strongly punctured, with the shoulders evidently less prominent,

and with a rather distinct impression in the middle of the pronotum, behind which there is sometimes

present a yellowish spot.

Long. 34 millim.; lat. int. hum. 14 millim.

Hab, GuaTEMALA, Quezaltenango 7800 feet (Champion).

Since writing the above, I have received a representative specimen of M. lugubrina

from the Stockholm Museum from Dr. Aurivillius; it does not, however, answer to

Stal’s description, for it has the tegmina entirely hyaline with the veins vitreous,

whereas Stal says of the species (/. c. p. 32) “tegminibus, parte apicali excepta,

brunneis, fusco-venosis.”

10. Micrutalis nigrolineata.

Acutalis nigrolineata, Stal, Stett. ent. Zeit. 1864, p. 72’.

Hab. Mexico (Mus. Holm.1; Mus. Vind. Ces.).

This species is not represented in our collection; it is testaceous, with a dark central

line running down the pronotum and an abbreviated dark line on each side of it; these

lines, however, are variable, and there are two specimens from Bogota in the Vienna

Museum, labelled respectively “ bdiguttata” and “ litterata” (apparently MS. names of

Signoret), which evidently belong to the same species. Apart from the colour, the

MICRUTALIS.—POLYGLYPTA. 121

insect may be known by the entirely hyaline tegmina and distinct dark veins; the

central basal area is so strongly petiolate that it appears almost as a discoidal area.

11. Micrutalis albivitta, sp. n.

M. lugubrine, var. parallele, maxime affinis, sed pronoto densius punctato et vittd distincté albida mox ante

apicem instructo, cetera nigro; tegminibus, apice excepto hyalino, nigris coriaceis, venis partem corlaceam

haud superantibus; abdomine pedibusque nigris, his partim brunneis.

Very like M. lugubrina, var. parallela, but easily distinguished by the very distinct white band running across

the pronotum just before the apex, which is the only marking on the upper surface, except a very small

line at the margin near the shoulders (usually present in most of the species of the genus), and especially

by the fact that the venation of the tegmina appears to be confined to the coriaceous portion.

Long. 4 millim. ; lat. int. hum. 2 millim.

Hab. Mexico, Cuernavaca (Bilimek, in Mus. Vind. Ces.).

Apparently quite distinct from M. lugubrina.

Besides the species of Micrutalis above described or noticed, there is in the Vienna

Museum an example from Mexico labelled “flaviceps, det. Stal” (apparently a MS.

name), which appears to be a very small variety of 1. malleifera, with the apical part of

the pronotum darker. ‘There is also among the undetermined insects in the Stockholm

Museum a Micrutalis which, at first sight, superficially resembles M. albivitta, but is

differently shaped and sculptured, and very distinct by reason of the hyaline tegmina

and dark veins, and the presence of a small area behind what usually constitutes the

central petiolate basal area, which latter, therefore, in this case becomes properly

discoidal; the insect, however, is imperfect, and I have therefore not described it.

In the ‘ Bidrag till Rio Janeiro-Traktens Hemipter-Fauna’ (pp. 32, 33) Stal describes

seven species of the genus Acutalis (A. plagiata, geniculata, semipallida, semialba,

modesta, lugubrina, and mesta), apparently from single insects or very small series, for

he mentions the female only of six, and the male only of one, and he adds the note,

“ Non nisi coloribus inter se differunt fere omnes species hic descripte ; forte tantum

varietates, quod melius docebit experientia.” ‘The series in our collection helps to clear

up certain points, but very probably when a still larger amount of material has been

obtained some of the species above described may have to be united together.

POLYGLYPTA.

Polyglypta, Burmeister, Handb. Ent. ii. 1, p. 142 (1835); Fairmaire, Ann. Soc. Ent. Fr. sér. 2, iv.

p. 296; Stal, Ofv. Kongl. Vet.-Ak. Forh. 1869, p. 240.

Numerous species have been described as belonging to this genus, which appears

to be confined to Central America and the north-western portions of South America.

They are elongate insects, of a black, brownish, or straw-colour, with the pronotum

produced into a point before and behind, and they closely resemble the long grains of

certain cereal plants, their likeness to which appears to be protective. A considerable

number of the so-called species have already been sunk by Stal and Butler as

synonyms, and I have gone further than Stal has in one or two cases. No such series of

the genus as that in our collection (numbering more than two hundred examples) has

ever before been brought together, and it is evident from an examination of these that

in many respects they are extremely variable insects, and that certain species which

have been described on single or at most on two or three specimens will not stand.

One of the chief characters that authors have made use of is derived from the number

of coste or raised ribs on each side of the pronotum; I find, however, that though it

certainly is a help in some cases, yet, as a rule, it is most misleading, for the third costa

from the dorsal costa (counting the dorsal costa as the first) is certainly variable in form

among specimens belonging to what is undoubtedly the same species, being sometimes

almost entire, sometimes half-defined, and sometimes rudimentary ; the costal margin of

the tegmina, moreover, is coloured like the pronotum and furnished with two or three

coste, which project beyond the sides of the pronotum and lie close against it when the

insect is at rest, and appear at first sight as if they belonged to it, and these have been

counted in by certain writers in their descriptions. Species have also been formed on

the deflexion or reflexion of the anterior or posterior extremities, which is a very

misleading character.

After a very careful examination of the series before me I feel that, with the excep-

tion of a comparatively small percentage, they might all be arranged as forms of one

species, although those at the opposite poles would appear entirely different, and a

considerable amount of further material and study will be necessary before the synonymy

of the species can be regarded as in any way settled.

The larva of P. costata, of which there is a single specimen in our collection, from

Atoyac in Vera Cruz, is almost 20 millim. long, pisciform, narrow, and elongate, of a

greyish-testaceous colour, probably greenish in life, with the last segment of the

abdomen very long (about 5 millim.), slender, and pointed, and with the process in

front of the eyes (which are large) about 6 millim. in length, constricted at about

2 millim. from the eyes, and from thence widened and flattened and subcuneiform at

the apex; the legs are long and slender.

I believe that the synonymy above given is correct, but exception may be taken to

the inclusion of P. dogotensis under P. costata: Stal separates the two insects on the

formation of the head and forehead and the number of the coste; but the latter

character is certainly misleading, and with regard to the former, though the head appears

to be slightly variable in shape, yet it is not sufficiently so to found a species upon, and

the difference of colour which often appears to occur in some specimens makes it seem

rather longer or shorter, although, in fact, the difference is only apparent. Moreover,

in the case of the specimens of P. bogotensis in Signoret’s collection (referred to as

typical specimens by Fairmaire) the head appears shorter and less angled than in those

labelled P. costata and P. nigriventris, whereas, according to Stal, the reverse ought to

be the case: if there were any males of P. bogotensis extant differing from the males of

P. costata, the case might be altered, but I have never seen any male of that insect.

Mr. Butler, indeed (/. ¢. p. 210), quotes both male and female as being in the British

Museum ; but the four specimens at present placed under the species in the collection

are all undoubtedly females, and I think are certainly P. costata.

With regard to P. reflexa it was described by Mr. Butler on a single specimen ; in

our series there are several examples among the males of P. costata that resemble it

in the reflexion of the horn, and in one or two specimens there is quite as marked a

deflexion. Mr. Distant has kindly lent me the type of P. godmani, and it is evident

that he has inadvertently counted in the external coste of the tegmina, for there are

only seven coste proper on the pronotum (one dorsal and three on each side), whereas

he mentions it as having thirteen, and in other respects it agrees with P. pilosa, which

is now universally considered to be the male of P. costata.

markings proceeding from the central band on each side ; dorsal horn slightly but plainly reflexed.

Long. 13-15 millim.

Hab. Mexico, Orizaba (Bilimek, in Mus. Vind. Ces.); Guatemata (Mus. Roy. Belg.),

This is an insect of about the same size as the ordinary run of P. costata, which

stands in the British Museum collection under P. dorsalis, and in the Belgian

Museum collection as P. maculata?; and in Signoret’s collection there is a specimen

placed apart and labelled “ P. costata, det. Signoret.” Iam inclined to think that the

, . *162

124 HEMIPTERA-HOMOPTERA.

example in Signoret’s collection is rightly determined, although some ot the specimens

certainly appear to run into extreme forms of P. dorsalis. The coste on the pronotum

are very variable, some specimens having four on each side besides the dorsal costa,

others three and an abbreviated one, while one (which, perhaps, belongs to a different

species) has three only, and another has three and an attenuated one on each side

and three and two abbreviated coste on the other.

All the specimens examined are females. One from San Juan is figured.

This is an extremely variable species, both in size and colour. The ordinary form is

testaceous, with the back broadly dark, sometimes almost black, sometimes reddish ; in

a few specimens the ground-colour is greenish. The dark colour has a tendency to

spread, and some specimens are almost entirely of a reddish-fulvous colour (P. fusca,

Butl., is apparently one of these), while the variety of the male usually known as

P. pallipes is almost entirely of a deep black colour.

I have excluded the larger forms which are by some authors referred to this species,

and the difference of size is by this reduced, so that the specimens range from 9 millim.

to 12 millim., and are narrower or broader in proportion. I am by no means sure,

however, whether P. maculata, Fairm., and P. tricolor, Butl., ought not to be referred

to this species. ‘The males of the species described below as P. dispar are also inter-

mediate forms, but the females appear to be quite distinct. Apart from the other

differences of the specimens inter se the punctuation is also variable; there are, for

instance, two typical specimens of P. dorsalis in our collection from the same locality

and mounted on the same card, and both females, of which one is comparatively finely

and the other coarsely punctured.

This species may be known by its dark brown colour and the yellow markings at

the sides, which are fairly constant, and consist of three spots on each side, of which

the two front ones are sometimes confluent. The pronotal horn is short and blunt.

The male and female appear closely to resemble each other. ‘The descriptions of

Burmeister and Amyot and Serville clearly apply to this insect, which appears to be

very distinct. Burmeister assigns eleven coste to the pronotum, whereas Amyot and

Serville mention nine only; but this probably arises from the confusion caused by

variation in different specimens.

Amyot and Serville * give “‘Savana” as the locality for their P. favomaculata ; but

whether Savannah in Georgia, the West Indies, or S. America is meant is uncertain.

This species is allied to P. maculata, but is narrower and more elongate, with the

P. brevivitta, Walk., appears to be allied to this species, but is smaller and differs in

other particulars.

MaLA (Sad/é), San Joaquin in Vera Paz (Champion).

There are five specimens among the undetermined material in the Vienna Museum

labelled “‘ Bilimek, Mexico,” which appear to be the true P. lineata of Burmeister,

answering to his description in size and structure of pronotal horn. Most of the

examples I have seen are considerably larger, with the horn more produced and in

126 HEMIPTERA-HOMOPTERA.

some cases reflexed. The cost appear to be very variable in number. Of two

specimens before me taken by Bilimek in Mexico, which agree in size and shape,

and appear to have been taken at the same time, one has nine coste and the other

thirteen (one or two being abbreviated), and Signoret’s specimen of P. tredecim-costata

has only eleven coste counting a rudimentary one. It is quite pessible that P. lineata

as here defined may be hereafter split up into several distinct species; but it might

perhaps be of advantage to define the following variety :-—

Var. major.

This variety might be described as a separate species were it not for intermediate

3S. Angustior, cornu pronoti plerumque leviter recurvato, et costis plerumque totis nigris, ad latera partim

testaceis.

Female. Rather broad at the shoulders, with the pronotum produced into a moderately long and almost straight,

sometimes slightly recurved, horn in front, with nine cost, which are either entirely of a light testaceous

colour (so that the insect appears to be marked with fine, regular, light and dark lines) or are partially

dark (so that the dorsal portion appears more or less clouded with black).

Male. Smaller and narrower than female, with the pronotal horn, as a rule, slightly recurved, and with the

black colour of the pronotum prevailing, but with the lateral coste partly testaceous.

In both sexes the underside of the horn and the head are more or less testaceous, the markings being similarly

coloured.

@. Long. 11 millim. ; lat. max. 23 millim.

3. Long. 10 millim. ; lat. max. 2 millim.

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

The female of this species is very distinct, but the male superficially resembles

varieties of allied species; it has, however, a facies of its own, and I feel almost certain

that the insects are the male and female of one species, although it is quite possible

that future workers may come to a different conclusion.

Elongata, sat robusta, brunnea, unicolor, linea dorsali maculisque quibusdam dilutioribus, vel testaceo-adspersa ;

pronoto antice in cornu brevissimum obtusum producto, ad humeris lato, inde ad apicem modice acutum

regulariter angustato, novem-costato ; tegminibus hyalinis, margine costali brunneo, venis interioribus

nigro-fuscis ; pedibus sat longis, totis testaceis, vel femoribus plus minusve nigricantibus.

A rather stout species, which may be distinguished by its exceedingly short blunt horn and broad shoulders ; the

colour is variable, apparently, lighter or darker brown with lighter markings ; the pronotum is deeply but

comparatively finely punctured, with four costs on each side, and is gradually narrowed from the shoulders

POLYGLYPTA.—BILIMEKIA. 127

toa moderately acute point, which is, however, rounded at the extreme apex; the punctuation is rather

stronger in front of the shoulders ; tegmina hyaline, with the veins brown exteriorly, but fuscous or black

on the disc.

Long. 9 millim. (sine cornu 8 millim.); lat. int. hum. 23 millim.

Hab. GuatemMaa, Volcan de Agua 8500 to 10,500 feet (Champion).

Two male specimens. At first sight, this insect almost appears as if it might form

the type of a new genus; but the tegmina appear to be of the ordinary Polyglypta

type, and there are no other differences sufficient to distinguish it from that genus.

There are specimens from Mexico in the Vienna and Stockholm Museums which are

very closely allied to this species, except that they are slightly smaller and rather

differently sculptured: I at first described them under a separate name, but, on further

examination, I have come to the conclusion that they can scarcely be regarded as

distinct ; in certain points, however, they seem to lead on to extreme forms of the

very variable P. dorsalis.

BILIMEKIA, gen. nov.

Corpus elongatum, parallelum; pronoto ab humeris in cornu longum et obtusum producto, fortiter pone oculos

ad latera emarginato; dorso ab apice cornus usque ad apicem pronoti recto, hoc lato, truncato; humeris

haud prominentibus ; metopidii margine supra clypeum fere recto, clypeo lato, late et minus alte

emarginato; pronoto leviter costato; tegminibus areis apicalibus tribus, area discoidali una subtriangulari ;

tibiis anticis et intermediis latis, subfoliaceis.

Body long and parallel, with the posterior extremity of the pronotum truncate, and the front portion produced

into a long blunt horn, the upperside of which is straight and level with the back of the pronotum, the under-

side being slightly curved. The tegmina are almost entirely hidden by the pronotum, only the extreme

edges being visible, and have only three apical areas, instead of five as in Polyglypta, and one subtriangular

discoidal area. The wings appear to be veined much as in the last-named genus, with three apical areas.

The anterior and intermediate tibie are broad and subfoliaceous. The general shape is exactly that of a

steel-pen nib. —

The characters above mentioned abundantly distinguish this genus, which in several

important points differs from Polyglypta, although in others it is evidently allied

to it. |

I have named the genus after Herr Bilimek, “a friend and companion of the

Emperor Maximilian in Mexico, and a very eager collector,” as Herr Handlirsch

informs me; all the specimens I have seen were obtained by him, and a very large

proportion of the specimens from Central America in the Vienna Museum have his

name attached to them.

1. Bilimekia styliformis, sp. n. (Tab. VIII. figg. 9, 9, J.)

Stramineo-testacea, unicolor, pronoto subtilius punctato, multicostato; cornu pronotis ad basin lato, apice

obtuso, carinato; oculis sat magnis, testaceis ; ocellis distinctis, ab oculis quam inter se minus remotis ;

tegminibus hyalinis, venis testaceis.

Of a unicolorous testaceous straw-colour, probably lighter in life, with the pronotum rather finely punctured

128 HEMIPTERA-HOMOPTERA.

and furnished with from nine to a dozen fine coste on each side; the pronotal horn is broad at the base

and has five or six coste on each side; tarsi occasionally somewhat darker than the rest of the legs.

Long. cum cornu 13 millim.; ab oculis ad apicem pronoti 8 millim.; lat. max. 2 millim. (d 2.)

Hab. Mexico (Bilimek).

2. Bilimekia minor, sp. n.

Duplo minor, cornu pronoti breviori, et lateribus utrinque sex- vel septem-costatis.

Very like the preceding but very much smaller, with the pronotum rather more finely punctured and with

fewer cost on each side, and the pronotal horn much shorter in proportion.

Long. cum cornu 7-8 millim.; ab oculis ad apicem pronoti 43-5 millim.; lat. max. 14 millim. (d 9.)

Hab. Mexico, Cuernavaca (Bilimek).

POLYGLYPTODES, gen. nov.

Polyglypte affinis, sed cornu pronoti a latere viso, ad basin latiori, et minus abrupte producto; capite sat

magno, clypeo lato, modice semicirculariter exciso ; tegminibus areis tantum tribus apicalibus, undque

discoidali, oblonga, prope apicem sita instructis.

This genus is allied to Polyglypta and Bilimekia. From the former of these it may

be distinguished by its finer sculpture and less abrupt horn (in which point, however,

Polyglypta ague forms a transition between the two genera), and especially by the

venation of the tegmina, which have only three apical areas, and the costal portion

divided into three long basal areas instead of two asin Polyglypta. From Bilimekia

it may at once be known by its shape and by the oblong discoidal cell of the tegmina,

as well as by the fact that Bilimekia has only two long basal areas on its exterior

portion, as in Polyglypta.

The three species here described differ more or less in shape and general appearance,

but agree in the generic characters above given.

1. Polyglyptodes cucullatus, sp. n. (Tab. VIII. figg. 10, 10a, 8.)

Elongata, robustior, tota testacea (an viridi-testacea ?), pronoto antice sinuatim in cornu breve, ad basin latum,

ad apicem acutum, utrinque multicarinatum producto, dorso subrotundato, lateribus subparallelis in

apicem obtusiusculum contracto, distincte et dense sed minus profunde punctato, undecim-costato ;

tegminibus hyalinis, venis pallidis; pedibus testaceis.

Elongate, but comparatively stout, of a unicolorous light testaceous colour, which is probably greenish in life ; pro-

notum with the back slightly rounded, sinuate just above the shoulders, and produced into a short, porrect,

moderately sharp horn, which is broad at the base and resembles a conical cap; at the sides of the horn

there are several coste ; the sides of the pronotum are subparallel, very slightly rounded, and gradually

contracted behind into a blunt apical process which reaches just as far as the apex of the tegmina; the

punctuation of the pronotum is close and distinct, but not coarse, and on each side there are five or six

fine but distinct coste ; the latter character, however, is variable, and one specimen before me has five on

one side and six on the other; legs testaceous.

Long. 8 millim. (sine cornu 6 millim.); lat. max, 2 millim.

Hab. GuaTEMALA, near the city (Champion).

Three specimens.

2. Polyglyptodes affinis, sp. n.

Precedenti affinis, sed flavo-testacea, longior et angustior, cornu pronoti longiori et rectiori, carinis utrinque

rarioribus et magis elevatis ; pronoto ad latera fortius punctato, dorso fere recto, haud sinuato, lateribus

minus rotundatis. —

Allied to the preceding, but of a more yellowish-testaceous colour (which may be different in life), and evidently

longer, narrower, and less robust. The horn of the pronotum is considerably longer, more slender and

straighter, and has fewer and stronger carine at the sides. The back is almost straight throughout, from

the tip of the horn to the apex of the pronotum, which is more strongly punctured at the sides, and has

the coste, as a rule, more elevated, and the sides straighter, and is more gradually produced to a point

both in front and behind, if viewed from above.

Long. 10-104 millim. (sine cornu 8 millim.); lat. max. 1? millim.

Hab. Mexico (Bilimek, in Mus. Vind. Ces.).

Three female specimens.

3. Polyglyptodes scaphiformis, sp. n. (Tab. VIII. figg. 11, 11a, 4.)

Parva, elongata, angusta, fusca vel fusco-brunnea, capite metopidioque testaceis, pronoto in cornu breve,

obtusum, utrinque carinatum, levissime deflexum producto, distincte minus fortiter punctato, plerumque

undecim-costato, lined dorsali plus minusve elevata, interdum nigricanti, dorso a latere viso ab apice

postico usque ad apicem cornus equaliter et leviter rotundato, haud sinuato; tegminibus hyalinis, venis

fuscis ; pedibus testaceis, interdum ad partem fuscis, tarsis nigricantibus.

A small species, which viewed from the side appears to be slightly and evenly rounded from the anterior to

the posterior apex, like the shape of an inverted canoe; pronotal horn short and blunt and slightly

deflexed, but straighter in some specimens than in others, with the sides carinated; pronotum rather

finely but distinctly punctured, as a rule with five carinz on each side, dorsal carina more or less strongly

elevated, sometimes blackish ; tegmina hyaline, with brownish veins; legs mostly testaceous, with the

tarsi blackish. .

Long. 6 millim. (sine cornu 5 millim.); lat. max. 13-14 millim.

Hab. Guatemaa, Cerro Zunil (Champion).

Five specimens. At first sight this species looks very different to the two preceding,

but it cannot well be separated from them generically.

ENTYLIA.

Entilia, Germar, Rev. Ent. Silb. 11. p. 247 (1835).

Entylia, Fairmaire, Ann. Soc. Ent. Fr. sér. 2, iv. p. 299 (1846) (nec Burmeister, Rev. Ent. Silb.

iv. p. 181).

The limits of this genus are very uncertain, and the synonymy is in great

confusion owing to the variability of the species and the difficulty of distinguishing

them by any constant characters. ‘They are, as a rule, easily recognized by the deeply

cut sinuation of the pronotum, which is compresso-elevate and more or less sharply

carinate ; the differences, however, in a large series of specimens are very great, and

the gradation so complete that it is impossible to define the species with any approach

to certainty. Stél separates off E. concava, Germ., under a separate genus Publilia,

characterized by having the back of the pronotum convex and only slightly depressed

before or at the middle; it is, however, doubtful whether the genus ought to stand,

BIOL. CENTR.-AMER., Rhynch. Homop., Vol. II., January 1896. #17

130 HEMIPTERA-HOMOPTERA.

as certain species of Entylia in their extreme forms come very close to it, and Publilia

porrecta seems a further connecting form.

Germar described seven species, and Walker enumerated twelve: these Stal reduced

to five (including Pudblilia concava) ; but Butler (Cist. Ent. ii. p. 210), after stating that

he differs entirely from St&l in the synonymy which he gives to the species of the

genus, reinstates three of Walker’s species and adds two new ones, at the same time

allowing that he would have no objection to considering the whole of the forms which

he is discussing as varieties of one inconstant species; this I believe to be the best

solution of the difficulty. |

All the species hitherto described are from North, Central, or Tropical South

America.

In considering this genus it ought perhaps to be noted that Burmeister (Rev. Ent.

Silb. iv. p. 181, t. 36. fig. 8) has in some unaccountable way entirely mistaken

Germar’s characters for the genus, and identified it with what is really Parmula or an

allied genus.

All the specimens in our collection belong to the form £. inequalis, Butl., except

four or five which must be referred to his E. mira, and three of a peculiarly coloured

variety from Chiacam, Vera Paz. Its geographical range would seem to indicate that

all the forms cannot belong to one species; but large series of specimens from various

localities require to be examined before the question can be settled satisfactorily, and

PUBLILIA.

Publilia, Stal, Ofv. Kongl. Vet.-Ak. Férh. 1867, p. 553.

This genus was formed by Stal to receive Entylia concava, Germ., and is distinguished

by having the back of the pronotum convex, only very slightly depressed in or before

the middle. As above remarked, it is doubtful whether it will stand as a distinct

genus from Entylia, although in facies it is very distinct from the ordinary forms of

that genus.

Quoad formam coloremque precedenti simillima, sed cornu brevi lato porrecto, dorsoque pronoti ante cornu

In colour and general appearance closely resembling the preceding, but with a short and broad porrect horn in

front, and with the back of the pronotum slightly sinuate and less straight before the horn; the colour

is light brownish grey, with two more or less distinct lighter stripes on each side, and with a few very

scattered small dark markings, which are often almost, if not entirely, absent.

of: P. concava, but it is probably distinct ; the porrect horn is not a sexual difference.

P. porrecta is closely allied to Entylia, and ought perhaps to be placed at the end of

that genus; in this case, however, P. concava could hardly be formed into a separate

genus, and would have to be included, as of old, under Entylia.

METHEISA, gen. nov.

Elongata, capite longitudine haud multo latiori, oculis prominulis, metopidio simplici, vel protuberante, vel in

cornu breve porrectum extenso; pronoto subparallelo, angustato, distincte costato, ad apicem sensim

angustiori, apice acuto usque ad apicem tegminum producto, humeris leviter acute prominulis, dorso a

latere viso fere recto vel in medio leviter sinuato, apicem versus sensim levissime deflexo; tegminibus

parte fere dimidia intecté, areis apicalibus quatuor, discoidalibus duabus, alis areis apicalibus quatuor,

discoidali nulla; pedibus teretibus, tarsis posterioribus sat elongatis.

Elongate and subparallel, gradually narrowed towards the apex of the pronotum, which is acute and just

reaches the apex of the tegmina; head rather large, eyes prominent ; metopidium simple and rounded in

front or forming a right angle with the hinder part of the pronotum, or slightly protuberant, or with a

distinct short horn projecting from its front; upper surface of the pronotum costate, the shoulders

distinctly and sharply but minutely prominent; distance from the dorsum to the margin narrow ;

dorsum straight or slightly sinuate in the middle if viewed from the side ; tegmina with four apical and

two discoidal areas; wings with four apical areas and no discoidal area; areas of tegmina mostly oblong,

the third apical area, however, is more or less semicircular and stylate ; basal costal portion of the

tegmina opaque and punctured ; legs slender, the posterior tarsi elongate.

This genus is closely allied to Entylia and Publilia on the one hand, and to Hille

and Lucilla on the other. As will be noticed from the description, it is very variable

as regards the shape of the front part of the pronotum; the difference appears to

be in no way sexual, as there are females in our collection with and without the

frontal horn.

1. Metheisa lucillodes, sp. n. (Tab. VIII. figg. 13, 138 a.)

Colore variabili, viridi vel viridi-testaceo vel fusco vel fere nigro, cornu pronoti (ubi adest) infuscato;

capite fortius punctato, inter ocellos impresso ; pronoto dense sat fortiter punctato, carina centrali distincta,

costisque quatuor vel quinque (interdum abbreviatis) instructo; corpore subtus et parte opacd tegminum

cum colore dorsi congruente, pedibus testaceis, raro infuscatis.

Very variable in colour, green or greenish-testaceous, fuscous or almost black (the darker specimens showing

traces of one or two lighter bands), with the frontal horn of the pronotum, where present, in all cases

infuscate ; pronotum thickly and rather strongly punctured, with a distinct central keel, and with four or

five more or less regular and in some cases abbreviated cost on each side ; the underside and the opaque

and punctured part of the tegmina appear to agree in colour with the colour of the upper surface, but the

legs are nearly always testaceous, sometimes in part infuscate.

Long. 4-5 millim. ; lat. int. hum. 17-2 millim.

Hab. Panama, Bugaba, Volcan de Chiriqui 2500 to 6000 feet (Champion).

The discoidal areas of the tegmina are usually equal in size, but in some cases the

exterior one is very small.

This insect is very like small specimens of Lucilla viridula, but in that species the

dorsum is slightly protuberant behind, and not in front of, the shoulders.

Ennya, Stal, Berl. ent. Zeitschr. x. p. 387 (1866).

Hille, Stal, Ofv. Kong]. Vet.-Ak. Férh. 1869, p. 235 (ex parte).

The genus Ennya is separated by Stal from Hille on the ground that the corium is

destitute of a discoidal area; but this is incorrect, for the specimens of Oxygonia

chrysura which I have seen (which species, together with O. rujfipes, Stl apparently’

regards as the typical species of Ennya) have mostly one discoidal area at least present,

and occasionally two; the tegmina, however, in the group appear to vary in this

respect in the same specimens, and a thorough revision of the whole is very necessary.

It is by no means clear why Stal should have adopted the name of Ennya as a genus

for the reception of Oxygonia rufipes and O. chrysura, for O. rufipes is apparently

Fairmaire’s type species of Oxygonia (1. c. p.303). I have therefore preferred to retain

the name Oxygonia instead of Ennya for the species below referred to.

Mr. Distant described this species from a single poor example, and it was only

after a close examination that I came to the conclusion that the other specimens referred

to belonged to the same species; they only differ, however, in the dark markings of

the head and metopidium, which he describes as follows :—‘‘ Head and frontal portion

of the pronotum luteous, the last with two small black spots placed transversely and

close together on the centre immediately above the head, and a central fascia of the

same colour above these on the disc.” In all the other specimens I have seen the

black markings of the metopidium consist of two broad curved bands which meet the

post-humeral fascia of the pronotum, and are occasionally joined at the point at which

they approach nearest to one another by another frontal fascia; they show, however,

slight signs of variation, and in the type example almost disappear. Mr. Distant is

also wrong with regard to the tegmina, which he describes as “ black, with a large

hyaline spot a little before the apex”; they are large and hyaline, with the exterior

margin only broadly dark, the portion towards the base, as is usual in this genus, being

opaque and strongly punctured and coloured after the fashion of the pronotum, though

the black colour is always more prevalent ; a little before the apex of the margin there

is a hyaline spot. |

A rather short species, with the pronotum of a green colour, variegated above the shoulders and on more or

less of the disc with yellow, and with a thin black line extending from the front of the head to the middle

along the central carina ; the line is here interrupted, but is present again at the apex ; the shoulders are

distinctly, though slightly, prominent, and are black at the apex, and on each side above the shoulders

reaching from the front margin of the metopidium to the margin of the pronotum just behind the middle

there is a thin central black line, which is almost semicircular, and before the apex is a A-shaped line

reaching from margin to margin, the apex of which is sometimes acute and sometimes rounded; tegmina

hyaline, with the greater part of the exterior margin opaque and coloured like the pronotum, except that

the dark colour usually prevails, and with a fuscous patch at the apex ; underside and legs clear greenish-

species, and cannot be confused with any other that I have seen.

6. Adippe inconspicua, sp.n. (Tab. VIII. figg. 19, 19a.)

Preecedenti affinis, sed unicolor, virescens vel fusco-virescens, partibus anticis dilutioribus, et pronoto minus

eequaliter rotundato, supra viso antice prominulo, metopidio fere recto; tegminibus hyalinis, margine

exteriori ut in preecedentibus ; corpore subtus brunneo-testaceo ; pedibus testaceis.

Of a dull green or fuscous colour, with the head and metopidium and sometimes the space above the shoulders

much lighter, yellowish-green; prouotum less evenly rounded than in the preceding species, forming

more of an angle at the commencement of the metopidium, which is almost straight; if viewed from

above there is a distinct blunt angular projection of the central carina; the sides have the ribs between

the punctuation more distinct and regular than is usual in the genus, but in this the species appears to

vary; tegmina hyaline, with the exterior margin mostly opaque and punctured and coloured like the

. elytra, and with a fuscous spot just before the apex ; underside brownish-testaceous ; legs testaceous.

Long. 5 millim.; lat. int. hum. 23 millim.

136 HEMIPTERA-HOMOPTERA.

Hab. Panama, David in Chiriqui (Champion).

Four specimens, two of which are much darker than the others, but this is evidently

due to discoloration. The sculpture is somewhat variable. In general appearance

this species very closely resembles Amastris obtegens, F., which appears to be identical

with, or very closely allied to, Thelia tacta, Walk., but is easily separated by the

entirely different venation of the tegmina. The genus Thelia, according to Walker, is

made up of the most discordant elements, and includes species belonging to Antianthe

(Ianthe), Stictocephala, Carynota, Amastris, Telamona, Aconophoroides, and other

genera, the mixture of which has caused very great confusion, which has been worse

confounded by Stal neglecting purposely or accidentally to verify Walker's work in

certain cases.

7. Adippe inzqualis, sp.n. (Tab. VIII. figg. 20, 20 a.)

Brunnea vel rufo-brunnea, haud nitida, pronoto inequali plus minusve late nigro- vel nigro-brunneo-notato, sat

fortiter subrugose punctato, carina centrali acutd a latere visé rotundata leviter sinuata, et carina altera

acuta abbreviata inter hance et humeros prominulos instructaé ; tegminibus hyalinis, margine exteriori late

brunnea, punctata, ante apicem fuse; corpore subtus brunneo; pedibus testaceis, ad partem infuscatis.

A small species of a lighter or darker brown, rufous-brown, or brick-red colour, variegated with darker colour ;

dull, with the pronotum, if viewed from the side, evenly rounded and only very slightly sinuate, but if

viewed from above uneven, with a strong central carina and two almost equally strong abbreviated

carinze on each side of it, and traces of other coste beneath these ; the punctuation is close and distinct ;

tegmina hyaline, with the exterior margin broadly opaque, except before the apex, with the usual fuscous

patch near the apex; underside brown; legs testaceous, more or less infuscate.

Long. 4-44 millim. ; lat. int. hum. 2 millim.

Hab. Guatemata, San Juan in Vera Paz (Champion); Panama, Bugaba, Volcan de

Chiriqui 2500 to 6000 feet, Pefia Blanca 3000 to 4000 feet (Champion).

According to Stal’s definition of the genus, this species is intermediate between

Oxygonia and Adippe, as it is strongly carinated on each side of the central keel.

The general structure of the insect, however, is too near that of the preceding to

separate it, and it must be regarded as a connecting-link between these genera. It is

very variable in colour, the dark tint sometimes covering all the front part of the

pronotum, and sometimes being almost absent; at the apical portion of this colour there

is often a more or less defined lighter band, behind which the apex is broadly and uni-

formly testaceous, the separation being very abrupt; occasionally, however, the colour

is lighter in front and is terminated by a dark band. The single specimen from Pefia

Blanca presents some differences, and may eventually have to be referred to a separate

species.

An example from Bugaba is figured.

8. Adippe grisea, sp. n. |

Elongata, pronoto leviter punctato, brunneo-griseo, metopidio brunneo-marmorato, et dorso obscure variegato,

_ADIPPE.—ANTIANTHE. 137

regulariter a humeris prominulis ad apicem exteusis; tegminibus ut in specie preecedenti ; corpore subtus

pedibusque testaceis.

Elongate and proportionally narrow, with the pronotum subparallel in front and gradually narrowed behind,

finely punctured, with a central keel which is well marked, and, if viewed from the side, rather flatly but

evenly rounded, of a brownish-grey colour, marbled on the metopidium with darker colour and obscurely

variegated on the rest of the surface; on either side there are more or less regular coste ; tegmina as in

the preceding species ; underside and legs testaceous.

Long. 5 millim. ; lat. int. hum. 2 millim.

Hab. Panama, Bugaba (Champion).

The long and narrow shape and general sculpture will easily distinguish this insect

from the preceding.

ANTIANTHE, nom. nov.*

Janthe, Stal, Ofv. Kongl. Vet.-Ak. Forh. 1867, p. 554 (nec Marseul, 1865).

This genus comprises three or four species from Central or Tropical South America.

They may be known by the strongly elevated pronotum, which is highest in front and

covers a considerable portion of the tegmina, and the sharp horizontal pronotal horns,

and by the fact that the corium has two discoidal areas. The apex of the hind tibie

and the tarsi are peculiarly spined, as shown on Tab. VIII. fig. 216. It is hard to

determine how many species are really distinct, as they lead one into the other; this

is especially noticeable in a large series, such as that in our collection, which numbers

more than two hundred examples. ‘The size is very variable, but the males appear to

be always considerably smaller than the females from the same locality.

An example from Atoyac is figured.

Var. humilis, v. n.

Multo minor, dorso vix antice elevato, rotundato, cornibus obtusiusculis brevioribus.

A very small variety, with the dorsal ridge scarcely, if at all, elevated in front, and more or less evenly rounded,

and the horns of the pronotum much shorter and blunter than in average specimens of the type form.

If the large series from Yucatan stood alone, I should have no hesitation in describing

them as a distinct species; but the front part of the pronotum is slightly more elevated

in some of the specimens from Chontales and San Gerdnimo, and these again lead on

to others which may be classed either with the type or the variety, and also to small

male specimens of the type form from Atoyac, Orizaba, &c., so that a series can be

arranged with the transition complete.

Of this species we have received two males and three females from Mexico. It

differs from A. expansa in having the pronotum less elevated in proportion in front ;

the pronotum therefore appears lower if viewed from the side, and slopes much less

abruptly in a straight line to the apex, which is apparently longer. In the Vienna

Museum collection the specimens under A. expansa belong to this species, whereas a

large number of the true A. expansa are unnamed.

will easily distinguish this species.

GODINGIA. 139

GODINGIA, gen. nov.

Sat lata, robusta ; capite longitudine latiori, ocellis inter se quam ab oculis minus distantibus, oculis magnis

prominulis; pronoto antice depresso, lato, metopidio vix declivi, utrinque ad latera fortiter impresso,

postice sensim angustato, deinde abrupte in processum apicalem brevem contracto, carina centrali postice

distinctiori, dorso a latere viso fere quali, sed mox ante apicem abrupte depresso; tegminibus plerumque

intectis, corio areis apicalibus quinque (tertia stylata), discoidali und, alis areis apicalibus quatuor (secunda

stylata); pedibus cylindricis, tarsis modicis, equalibus.

Rather broad and robust; head broader than long, triangularly produced in front; ocelli set far forward,

nearer to one another than to the eyes, which are large and prominent ; pronotum depressed and convex in

front, with the metopidium very gradually declivous, broad almost to the apex and then abruptly narrowed

to a short broad point; dorsum depressed and almost level from above the shoulders, which are slightly

and obtusely prominent, until near the apex, where it is suddenly depressed and unites with the short

apical process ; central carina more distinct behind than in front; sides with a strong broad impression

on each extending from the shoulders to behind the middle, where they meet the dorsal carina, which is

at the point very distinct; tegmina ample, extending some way beyond the apex of the pronotum ;

corium with three veins proceeding from near the base, the ulnar veins not being united by a transverse

venule, with five apical areas and one discoidal, the third apical area being triangular and stylate; wings

with four apical areas, the second triangular and stylate; clavus and a small part of the corium covered

by the pronotum ; legs cylindrical. .

This genus is allied to Optilete, but differs in general shape, in the absence of a

second discoidal cell on the tegmina, and in the shape of the second apical area of the

wing, which in Optilete is oblong and not stylate. Its chief affinities perhaps are

towards Smilia, from which it may at once be known by the shape of the pronotum,

which in the latter genus is strongly elevated, compressed, acute, and highest in front.

I have much pleasure in naming this genus after Dr. Goding, as a slight acknow-

ledgment of the help he has given me.

1. Godingia guerreroensis, sp.n. (Tab. VIII. figg. 22, 224, 9; 28, 234, 3.)

Nigra vel fusco-picea, plus minusve nitida, capite testaceo, nigro- vel fusco-notato; pronoto distincte densius

Mas. Niger, magis nitidus, disco pronoti minus fortiter punctato, apiceque breviori, albo, nigro-limbato.

Femina. Fusca, minus nitida, disco prothoracis fortius densiusque punctato, apice longiori albido.

Black or fusco-piceous, with the head and front part of the metopidium testaceous, variegated with darker

colour; pronotum very finely pubescent, the pubescence being easily rubbed off, with the margins at the

shoulders, and a large oblique patch at the middle reaching the sides, and the apex, white or whitish;

tegmina hyaline, with the veins fuscous, in part testaceous towards the apex, apex broadly infuscate,

extreme base strongly punctured; legs and abdomen testaceous, the latter sometimes in part infuscate.

The male is shining black, less closely punctured than the female, with the markings clear white and the apex

of the pronotum shorter and bordered with black.

The female is fusco-piceous, somewhat variegated with piceous, with the edges of the whitish markings darker,

and is more closely and strongly punctured on the disc than the male, with the apex of the pronotum

longer.

Three females from Xucumanatlan and a male from Omilteme. One of the female

specimens is almost entirely testaceous, but this is, apparently, due to its not being

quite mature.

We figure a male from Omilteme and a female from Xucumanatlan.

ATYMNA.

Atymna, Stal, Ofv. Kongl. Vet.-Ak. Férh. 1867, p. 554.

This genus is very closely allied to Cyrtolobus, and perhaps ought not to be separated

from it. It bears just the same analogy to the last-named genus that Amastris bears

to Vanduzea.

Hepburn).

One discoloured female specimen from Chihuahua. This has been compared by

Dr. Goding with a typical example of Smilia castanee, Fitch, and he informs me that

it only differs in having a smoky band at the apex of the tegmina, a character in which

certain allied species are somewhat variable.

CYRTOLOBUS.

Cyriolobus, Goding, Trans. Am. Ent. Soc. xix. p. 257 (1892).

This genus, as well as Atymna, belongs to the group which has the apical area of the

wings stylate, and not sessile as in Zelamona ; itis closely allied to Smilia and Antianthe.

The tegmina have two discoidal areas, as in Antianthe, in Smilia one only is present.

The differences between some of the species are obscure, and it is difficult to deter-

mine with certainty, until more specimens are discovered, which of them ought to be

regarded as having true specific value. |

The specimen in the Vienna Museum is figured.

3. Cyrtolobus virescens, sp. n. (Tab. IX. figg. 1, la.)

Elongatus, angustatus, viridi-testaceus, capite subrugoso, remote punctato, pronoto fortius, haud profunde,

- punctato, carinato, antice convexo, leviter depresso, dorso fere sequali, humeris vix prominulis, lateribus

utrinque impressis, apice curvatim deflexo; tegminibus hyalinis, ad basin virescentibus, punctatis ;

corpore subtus pedibusque totis testaceis.

An elongate and narrow species, of a greenish-testaceous colour, perhaps bright green in life, with the

pronotum subrugosely and rather strongly, but not deeply, punctured; shoulders scarcely prominent ;

dorsum, if viewed from the side, almost even, carinate, slightly depressed in front, sides broadly impressed,

apex rather long, deflexed ; tegmina hyaline, greenish and rather strongly punctured at the extreme base ;

underside and legs testaceous.

Long. 9 millim.; lat. int. hum. 34 millim.

Hab. Mexico (Mus. Oxon.), Xucumanatlan in Guerrero 7000 feet (H. H. Smith).

In the specimen from Xucumanatlan there are two very obscure lighter bands behind

the middle and before the apex; but it is often almost impossible in the case of these

greenish-testaceous species to determine what was the real colour in life.

Slightly smaller than the preceding species, testaceous, obscurely variegated with castaneous or rufous-

brown; pronotum closely and strongly, and in parts subrugosely, punctured, impressed at the sides ;

‘dorsum carinate, evenly rounded from just above the head to behind the middle, and then considerably

testaceo-hyalinis, vitté magna nigro-brunnea ad apicem alteraque ad medium, convergentibus, et partem

vitreo-hyalinam includentibus ; corpore subtus pedibusque testaceis. .

Of a light castaneous-brown colour, almost unicolorous, except for the dorsal carina, which is variegated with

fuscous and testaceous; pronotum strongly punctured and deeply impressed on each side; dorsum, if

viewed from ‘the side, uneven, sinuate, and depressed in front, then slightly elevated for some distance,

and behind the middle again depressed and produced into a blunt apex; the tegmina are punctured at

the base and are testaceo-hyaline, with two large dark bands almost meeting and enclosing a vitreous

portion on the exterior margin ; in lighter specimens these bands are obscure, but the vitreous or testaceous

portions appear distinctly separated ; underside and legs testaceous.

magis elevato, posticeque abruptius sinuatim depresso, tegminibusque vitreo-hyalinis, ad apicem fumosis,

venis fuscis apicem versus dilute testaceis, valde differt.

Closely allied to the preceding, and possibly the male of it, as one of the specimens of C. vittatipennis comes

from the same locality; it is griseous in colour, with close and moderately strong fuscous punctuation,

and with the pronotum variegated with dark fuscous-brown ; the dorsum is much elevated in front, and

reaches its highest point a little behind the shoulders, from whence it sinks abruptly and somewhat

sinuately to behind the middle, and from thence is extended into a moderately long and blunt apex, which

is strongly impressed at the base, the sides being very strongly impressed just in front of this; tegmina

punctured at the base, clear hyaline, with the apex smoky and the veins almost black, but quite light

at the extreme apex ; abdomen dark above, testaceous below ; legs testaceous.

Long. cum tegm. 83 millim.; lat. int. hum. 33 millim.

Hab. Mexico, Xucumanatlan in Guerrero 7000 feet (A. H. Smith).

One male specimen. This insect certainly seems very distinct from any other

Cyrtolobus I have seen, although, as above stated, it may prove to be the male of the

preceding; I hardly think, however, that this will be found to be the case.

It will be noticed that nearly all the specimens here referred to come from elevated

districts, and that they are represented by very few specimens; they evidently form a

very difficult, though interesting group, and it is much to be hoped that more specimens

may be found by future collectors.

OPHIDERMA.

Ophiderma, Fairmaire, Ann. Soc. Ent. Fr. sér. 2, iv. p. 473 (1846).

This genus is distinguished by the broad convex dorsum, the approximate ocelli, and

OPHIDERMA.—TELAMONA. 148

the subtriangular and stylate apical third cell of the tegmina; the shoulders are very

slightly prominent, and the sides of the pronotum are very gradually and evenly rounded

to the apex, which is very blunt and reaches nearly to the apex of the tegmina.

1. Ophiderma mus, sp. n. (Tab. IX. figg. 3, 3a.)

Latius, sat robustum, capite magno subtiliter punctato, testaceo; pronoto densius fortiusque punctato, murino,

vel griseo-purpureo, griseo-variegato, linea centrali elevata nigra, punctisque plerumque obscuris, humeris

vix prominulis, dorso a latere viso leviter sed distincte sinuato, ante medium perpaullo elevato; tegmi-

nibus hyalinis, basin versus punctatis, basi medio et apice plus minusve infuscatis ; pedibus testaceis.

A broad and robust species; head large, finely punctured, and the eyes large and not very prominent ;

pronotum of a greyish-purple or mouse-colour obscurely variegated with grey, with a dark central line,

and with the colour obscurely arranged in bands of irregular breadth behind the middle; punctuation

close and rather strong, finer on the metopidium, the punctures being for the most part dark ; shoulders

very slightly prominent; dorsum, if viewed from the side, feebly but distinctly sinuate, very slightly

raised a little before the middle and scarcely depressed in the centre; tegmina hyaline, with the basal half

more or less punctured, and with a fuscous patch at the apex, and a testaceous band, fuscous externally,

in the middle; legs testaceous, claws and apex of the tibize infuscate.

Long. 7 millim.; lat. int. hum. 33 millim.

HILLE.

Hille, Stal, Ofv. Kongl. Vet.-Ak. Férh. 1867, p. 555; ibid. 1869, p. 235.

The single species referred to this genus scarcely differs from Oxygonia, except

in the form of the dorsum, and it ought, perhaps, to be included under it, as the

character afforded by the presence or absence of a discoidal area on the corium is of

doubtful value.

Very like the preceding, but rather larger, and easily known by the much more broadly prcminent shoulders,

and by the shape of the dorsal protuberance, which is more raised in front (where it forms a second

rounded protuberance) than behind, and is sinuate in the middle, the hinder angle being acute; the

colour is griseous, variegated with fuscous.

Long. cum tegm. 11 millim.; lat. int. hum. 7 millim.

Hab. Mexico, Amula 6000 feet and Xucumanatlan 7000 feet, both in Guerrero

(H. H. Smith).

A male from Amula and a female from Xucumanatlan. This species appears to be

closely allied to 7. ¢ristis, Fitch, as well as to T. salvini, Dist., and 7. spreta, Goding.

The male is figured.

Telamona salvini, Dist. Ent. Monthly Mag. xvi. p. 11 (1879) '.

Hab. GuatemMa.a, Chinautla 4100 feet (Salvin 1), Guatemala city (Champion).

The specimens from the two localities differ somewhat inter se, and may belong to

two different species. The insect is distinguished by the truncate dorsal process; it is

very closely allied to 7’. spreta, Goding, and is perhaps not really distinct from it.

The latter species has the dorsal protuberance broadly and evenly truncate as in

T. salvini, but it is set further back from the metopidium and has the two apical

angles rounded ; in 7. salvint the hinder angle is sharp and somewhat produced, and

the front angle is more broadly rounded. |

The colour of this species, like that of the other. members of the genus, is variable ;

the pronotum in the type specimen is almost unicolorous brown, with darker markings

behind, whereas in the example from Guatemala city it is much mottled with griseous

and fuscous-brown.

6. Telamona albidorsata, sp.n. (Tab. IX. figg. 8, 8a.)

Fusco-picea, nitida, pronoto fortiter, postice rugosius, punctato, ad latera maculis minutis albidis irrorato et

apice rotundato, antice abrupte in metopidium sinuatim declivi, postice lenius in processum posticum

mergente, apice hujus nigro, humeris obtusis, leviter prominulis; tegminibus apicem prothoracis super-

antibus, parte apicali infuscaté; pedibus piceo-testaceis.

Of a fuscous colour, with the pronotum furnished with a broad and distinct white or greenish-white band

along its whole upper ridge from near the apex of the dorsal protuberance to the apex of the posterior

process; the sides, too, are irrorated with small spots of the same colour; the dorsal protuberance is

simple, slightly porrect, rounded at the apex, abruptly and with a very slight sinuation declivous in front,

and behind merging with a strong and even sweep into the posterior process, with which it forms a very

obtuse and hardly perceptible angle behind the middle; tegmina fusco-hyaline, clearer on the external

margin and broadly infuscate at the apex ; legs pitchy testaceous.

Long. 94 millim. ; lat. int. hum. 42 millim.

Hab. Mexico, Rinconada in Vera Cruz (Schaus).

7. Telamona satyrus, sp. n. (Tab. IX. figg. 9, 9a.)

Brunnea, piceo griseoque variegata, capite leviter, pronoto sat fortiter punctato, postice rugoso; humeris ut in

specie precedenti valde prominentibus, auritis; protuberantia dorsali simplici, haud truncata, apice

rotundato, in metopidium sat abrupte declivi, postice ad basin fortiter impresso et sinuatim in processum

posticum mergente ; tegminibus hyalinis ad apicem et interdum in medio brunneis; pedibus testaceis,

tarsis infuscatis.

A rather large species, of a brown colour, variegated with fuscous and griseous ; pronotum strongly punctured,

with traces of rugose raised lines at the sides; shoulders strongly prominent, auriculate ; dorsal protuber-

ance nasute, rounded and slightly deflexed at the apex, with a deep and strong, though small impression

on each side at the base; the dorsum, if viewed from the side, extends in a broad sinuation into the

posterior process, which is long and nearly reaches the apex of the tegmina ; the latter are hyaline, with

the apex at least brown or smoky ; legs testaceous, with the tarsi infuscate.

Long. 103-11 millim.; lat. int. hum. 7 millim.

Hab. Guatemana, Quiché Mountains 9000 feet, San Gerénimo 3000 feet (Champion).

The form of the dorsum will at once separate this species from either of the pre- —

ceding ; if viewed from the side the type specimen bears a strong resemblance to the

head of a satyr, with ears, nose, mouth, and long pointed beard.

The specimen from San Gerénimo is figured.

Subfam. CENTROTINA.

The members of this subfamily may be known by the presence of a distinct and

more or less uncovered scutellum. Certain of the genera, as before observed (anted,

p- 2), are destitute of the process of the pronotum which is the chief characteristic of

the Membracide, and the real position of one or two is therefore somewhat uncertain.

The Central-American genera may be distinguished as follows :—

I. Pronotum with a longer or shorter posterior process, usually starting

from the base, but occasionally from the front.

1. Posterior process of the pronotum not or scarcely reaching beyond

the scutellum, or at most not beyond the middle of the body.

A. Pronotum without sharp lateral horns, usually simple, but in

one or two instances with broad, porrect, auriculate processes.

a. Posterior process of the pronotum lying close along the scu-

tellum, or at least touching the tegmina, if viewed from the

side.

at. Outer discoidal area of the tegmina removed by the

breadth of a whole area from the anterior margin ;

five distinct and well-marked areas reaching the apex.

more or less oblong, and, as a rule, not much

smaller than the inner discoidal area, which is also

oblong . . 2. 1. ee ee ee es

bb. Outer discoidal area stylate, subtriangular, consi-

derably smaller than the inner discoidal area, which,

if present, is trapezoidal, but is sometimes wanting.

bt. Outer discoidal area of the tegmina very small, touch-

ing or almost touching the outer marginal vein ; inner

discoidal area circular and depressed; four distinct

apical areas only reaching the apex (if a fifth is pre-

sent it is very minute and evidently abnormal) .

6+. Tegmina with three discoidal areas.

at. Posterior process of the pronotum triangular, broad

at the base and gradually narrowed to a blunt point

just beyond the middle of the body .

Hab. Mexico (Sallé', Mus. Holm.1), Jalisco (Schumann).

The very long, sharp, and strongly divergent horns will easily distinguish this species.

The specimen from Jalisco, a female, is somewhat different from a typical example

kindly lent me by Dr. Aurivillius ; it is shorter and darker, with the base of the tegmina

more plainly infuscate, and the pronotal horns straighter and less elevated. Stal, how-

ever, in his description of the species, says ‘“‘ cornubus subrectis vel leviter curvatis,”

PLATYCENTRUS.—CAMPYLOCENTRUS. 149

and speaks of the colour as ‘“fuscus vel fusco-ferrugineus.” Our specimen, moreover,

is not quite perfect, and, under the circumstances, I do not like to separate it.

The specimen from the Stockholm Museum is figured.

This species may be readily distinguished from the preceding by the broad and blunt

horns, which, if viewed from the front, are strongly deflexed at the apex.

Through the kindness of Dr. Aurivillius, I have been enabled to verify these two

insects by comparison with typical specimens in the Stockholm Museum.

CAMPYLOCENTRUS.

Campylocentrus, Stal, Ofv. Kongl. Vet.-Ak. Forb. xxvi. p. 289 (1869).

According to Stal’s arrangement this genus appears to be somewhat heterogeneous,

containing Centrotus curvidens, Fairm., and C. subspinosus, Fairm., as well as C. hamifer,

Fairm. (nec Walk.), and its allies. In general facies, however, and in other respects,

the first two species seem abundantly distinct.

more depressed and level on its upper surface than in the allied forms; it varies slightly

in size. The conspicuous white patches on the scutellum are sometimes rubbed off,

and some specimens are browner than others. Fairmaire! describes the tegmina as

« jaunes, transparentes, une tache blanchatre a la base”; but he apparently had a very

light-coloured specimen before him. In the ordinary examples the tegmina are fusco-

hyaline, with the costal margin and a more or less distinct patch on the interior margin

under the apex of the pronotal process dark, and with a distinct luteous or orange

spot at the base.

The Centrotus hamifer mentioned by Walker (List of Homopt. Ins., Suppl. p. 159)

as from Port Natal must be referred to another species.

with the centre of the tegmina more or less hyaline and the margins broadly fuscous.

Closely allied to C. obscuripennis, from which it may be distinguished by its larger

size, the quite differently-coloured tegmina, and the narrower and more reflexed

pronotal horns, as well as by the strong confluent tomentose patch at the base of the

scutellum. From C. hamifer it may at once be known by the much more arcuate

pronotal process.

a little beyond the apex of the abdomen, curved above the scutellum, and strongly lobed underneath in

152 HEMIPTERA-HOMOPTERA.

Very closely allied to Campylocentrus, but with the tegmina quite differently veined, there being five apical

areas (two on the external margin, the one nearest the apex being very small, the next two large, and

the external one smaller, and rounded at the apex, where it is joined in the centre by the marginal vein),

and two discoidal areas, of which the interior is almost circular and the exterior very small. In one of

the species below described the posterior process of the pronotum is very strongly sinuate on both its

surfaces, in the other the sinuation is only slight, so that it does not form a good character.

It will be noticed that the number of apical and discoidal areas of the tegmina are

the same as in Campylocentrus, but their shape and distribution are very different, and

the tegmina, though more or less pellucid, appear to be more coriaceous, with the

veins thicker and coarser.

their upper surface, and with a long process, which reaches beyond the apex of the abdomen, and is

strongly sinuate on both its upper and lower margins, and is lobed in the middle, the lobe being often

more or less merged in the sinuation; tegmina hyaline, variegated with black, black at the base, with a

luteous or whitish spot a little before the base, which is often indistinct; legs black or pitchy, with the

tarsi, and sometimes the apex of the tibie, lighter.

So far as I have been able to judge, the differences above noticed are.sexual, but the

examples from Teapa (seven in number), and one from Atoyac, have the pronotal

process more strongly sinuate, and, where the tomentose pubescence is not rubbed off,

have only two minute spots, one on each side of the base of the scutellum. The

specimens from the other localities have the pronotal process less strongly sinuate,

and the pubescence, where present, forming a confluent patch at the base of the

scutellum, which is, however, sometimes very thin in the middle. In one small

specimen from Las Mercedes the pubescence is very thick and white, and in this

example the pronotal process is very slightly sinuate in the middle. It is possible

that I may have included two species under the above description.

Considerably larger than G. sinuatus, which it resembles in its general structure; pronotum rather strongly,

subremotely, and not deeply punctured, with the horns long, sharp, and reflexed if viewed from the front,

broad, cultrate, and carinate if viewed from above; posterior process elongate, lobed beneath at about the

middle, arcuate above the scutellum, slightly sinuate above the median lobe; scutellum with a large

confluent patch of tomentose pubescence at the base; tegmina black, with the apex broadly and the

central portion irregularly luteo-hyaline, and with a luteous patch before the base, the hyaline portion

prevailing in some specimens; the central areas are concave, and the veins thick and large; legs black,

the tarsi fuscous.

This insect very closely resembles one or two of the species of Campylocentrus, but

may at once be known by the venation of the tegmina. Apart from the difference in

size, it is very closely related to the preceding, of which it may prove to be a variety.

A specimen from the Volcan de Chiriqui is figured.

SPATHOCENTRUS, gen. nov.

Oblongus, leviter pubescens, capite magno, oculis sat magnis, prominentibus; pronoto pone metopidium brevi,

cornu sat magno utrinque armato, his acutis, a fronte visis fere rectis, carinatis, processu postico curvato, ad

apicem abdominis vix productis, venis crassis, areis discoidalibus duabus, fere equalibus; pedibus

teretioribus.

Closely allied in shape and size to Gnamptocentrus, but easily distinguished by the pronotal process being

arcuate above the scutellum, and much dilated and spatulate at the apex, which just touches the middle

of the body; the horns are of moderate size, and set at right angles to the side of the pronotum, being

almost straight, or scarcely perceptibly deflexed, if viewed in front; the tegmina are opaque, and punc-

tured at the base, with thick pubescent veins, and with two discoidal areas of nearly equal size.

This is a very distinct genus, and is interesting as connecting the forms like Campylo-

centrus &c. on the one hand, with those like Brachybelus, Amblycentrus, &c. on the

other. At first sight it looks like a Gnamptocentrus with the posterior part of the

pronotal process broken off, but when examined under a high magnifying-power this

proves to be not the case.

rufescent.

Long. cum tegm. 5 millim.; lat. int. corn. 23 millim.

Hab. Mexico (Mus. Oron.).

One female specimen, recently detected by myself in the Oxford Museum. It is

possible that the rufescent colour may be due to immaturity, and that the ordinary

colour may be much darker.

SPHAZROCENTRUS, gen. nov.

Genus Campylocentro affine, sed corpore elliptico, convexo, elongato-subgloboso, cornibusqde pronoti multo

brevioribus, sepius fere vel totis deficientibus facile distinguendus.

Allied in several respects to Campylocentrus, but easily distinguished by its elliptical, subglobose, and very

convex form, and the formation of the pronotal horns, which are, when most pronounced, short and very

blunt, and are often almost or entirely wanting, their place being taken by short and obtuse prominences.

Stal (Ofv. Kongl. Vet.-Ak. Férh. 1869, p. 289) includes the species from which the

above description is taken in Campylocentrus; but, if any weight at all is to be allowed

to facies and general appearance, it certainly ought to form the type of a new genus,

for hardly any two insects belonging to the same family could look much more different

than Campylocentrus hamifer and this species. ‘There is not much difference in the

venation of the tegmina between the two genera, but Sph@rocentrus has the tegmina

much duller and very minutely reticulate. The posterior process of the pronotum is

very stout, and strongly lobed beneath.

The larger and more distinctly horned specimens are mostly females, and the smaller

and darker specimens in which the horns are rudimentary are mostly males, but this

distinction cannot always be relied upon. The colouring of the tegmina is very

variable; the light and dark variegation is especially marked in the series from

Chilpancingo, which were all taken at a considerable altitude.

There is a single specimen from La Venta, Guerrero, which may belong to a different

species, but it is imperfect.

An example from San Isidro is figured.

This species is one of the smallest of the Centrotine. It is an obscure dark little

insect, with the pronotum clothed with griseous pubescence, and it may be known by

the short pronotal process being partly buried in the tegmina, the absence of any

pronotal horns, and the regular oblong apical areas of the tegmina. :

A specimen from Teapa is figured.

ISCHNOCENTRUS.

Ischnocentrus, Stal, Ofv. Kongl. Vet.-Ak. Forh. xxvi. p. 292 (1869).

This genus may be known by the peculiar posterior pronotal process, this being fine

and sharp, sometimes almost straight, but usually very gently curved downwards, though

occasionally a little reflexed, and stretching out like a small tail at a considerable

distance above the scutellum, beyond the apex of which it is only slightly produced.

I have not seen the types of Stal’s species, which appears to have been described from

a single male and female; but from his description there can be little doubt as to the

genus, and judging by the variation of size and colour in the small series from the

Volcan de Chiriqui, I feel certain that they both belong to one species, At first I

thought that the smaller specimens, which are unicolorous black, and range from

3-34 millim. in length, were the males, and the larger ones the females, but one of

the smaller ones, at all events, is a female.

Oblong, comparatively broad; head with the ocelli situated not far from the base; pronotum convex, without

horns or carine, except the central line, with the shoulders prominent, and with a long, strongly sinuate,

serpentine process, which is strongly elevated above the scutellum, and is not lobed beneath at the centre,

where it touches the tegmina ; tegmina partly subcoriaceous, with very thick veins; corium with five apical

areas, the external being very small and almost merged in the venation, and two discoidals, the external

being almost circular and almost touching the costal margin; clavus with two distinct veins on the disc,

one being near suture; lcgs slender.

This is a very distinct genus, and unlike any other known to me; it may at once be

known by the peculiar process of the pronotum and the venation of the tegmina.

side converging to the metopidium, and the shoulders, which are prominent, ferruginous ; pronotum dull,

thickly and distinctly punctured, with the posterior process ferrnginous and black at the apex, rather

Elongate; head with the ocelli placed not far from the base, and a little further from one another than from the

eyes; pronotum convex, with the shoulders prominent, and with two short but rather strongly elevated

carine on each side of the central line near the base, which are bluntly pointed in the centre, and are most

conspicuous if viewed from the front; posterior process long, nearly reaching the apex of the abdomen,

gently sinuate, not lobed beneath, raised above the scutellum, which is longer than broad; tegmina

elongate, with the extreme base opaque and punctured, and the rest hyaline; corium with five apical and

two discoidal areas ; clavus with one distinct vein ; wings with four apical areas; legs slender.

This genus is allied to Ischnocentrus, but may readily be known by the.elongate and

gently sinuate posterior process and the lateral carine of the pronotum.

punctured, with the posterior process black, banded with testaceous ; scutellum fuscous, with the apex

light, and with a distinct patch of whitish tomentose pubescence on each side at the base; tegmina

hyaline, with the veins partly black ; the entire base is black and punctured, and this is followed by a

white spot; there is also a black patch on the interior margin just behind the middle, and the costal

margin is dark just before the apex ; legs more or less dark, but varying with the colour of the body.

discoidalibus duabus fere sequalibus oblongis, clavé vené una in disco distincté; alis areis apicalibus

quatuor; pedibus sat teretibus.

Elongate, with the head rather broader than long, the ocelli situated towards the base, but at some distance

from it; pronotum convex, broadest in the middle, where the shoulders are prominent, without horns;

posterior process very short, straight, lying along the scutellum, the apex of which it just reaches ;

tegmina long, opaque, except across the middle, with almost the basal half punctured, with five apical

areas and two oblong, almost equal, discoidal areas ; wings with five apical areas; legs, especially the

posterior pair, rather slender, with the intermediate and posterior tibia, as is the case in several allied

genera, minutely serrulate on their outer margins.

This genus is allied to [schnocentrus, but may be easily distinguished from it by the

formation of the pronotal process and the different character of the tegmina; these

latter, at first sight, appear to have three discoidal areas, but in reality there are two

only.

Rufo-testaceous, with the head and abdomen ferruginous and the breast black; head distinctly and not

strongly punctured; prouotum rather strongly and thickly punctured, with a smooth light testaceous

central line, which is produced behind into a very short process, the latter gradually, though slightly,

dilated towards the apex; tegmina testaceous, opaque, with the central portion hyaline, broadly and

strongly punctured towards the base; wings with fine testaceous veins ; legs testaceous, the claws black.

AMBLYCENTRUS, gen. nov.

Oblongus, pubescens, capite insequali, ocellis inter se et ab oculis fere pariter remotis, oculis magnis prominulis ;

pronoto convexo, supra caput late plicato, sine cornibus, humeris prominulis, a fronte visis subauriculatis,

dilatato ; tegminibus longis, pubescentibus, corio areis apicalibus quinque, discoidalibus duabus, clavo

venis duabus magnis, distinctis; alis areis apicalibus quatuor ; pedibus teretibus.

Elongate, strongly pubescent, with the head about as long as broad, and the eyes rather large; pronotum

convex, rather strongly plicate above the head, without horns, with the shoulders prominent, and bounded

on their inner side by a rather deep furrow, which makes them appear somewhat auriculate, if viewed

from the front; posterior process reaching a little beyond the apex of the scutellum, not elevated above

it, obtuse, if viewed from the side rather broad and gradually dilated behind ; tegmina long, pubescent,

with five apical areas and two discoidal, the clavus with two large raised veins on the disc; wings with

four apical areas; legs slender.

This genus is rather closely allied to Centriculus, but the general facies is very

different, and the longer head, subauriculate shoulders, and the very different tegmina,

together with the two strongly raised veins on the clavus, seem sufficient to distin-

guish it.

Of a fuscous-black colour, with the head clothed with thick and long greyish pubescence; pronotum strongly

and closely, and at the sides subrugosely, punctured, with a smooth central line extending behind into the

posterior process, which is short, testaceous, and black towards the apex ; tegmina black and punctured

at the base and thence variegated with black, obscure testaceous, and hyaline, the apex hyaline, the veins

large, partly black and partly testaceous, surrounded by long pubescence; wings with the veins black;

legs black, with the apex of the femora and tibie, the tarsi, except the claws, and more or less distinct

rings on the tibie, rufo-ferruginous,

This insect is quite distinct from any that I have yet seen. The specimen from

Xucumanatlan is figured.

Since writing the above description, I have received an insect from Omilteme,

Guerrero (8000 feet), which may belong to this species; it is rather smaller, with the

pronotal process narrower at the apex, and the apical areas rather straighter. Both

this and the type specimen are males.

PHAULOCENTRUS, gen. nov.

Oblongus, haud nitidus, dense subtiliter pubescens, capite lato, ocellis inter se et ab oculis fere. eque remotis,

perobtuse lobato, interdum cornuto ; processu postico tenui, brevi, pronoto ad basin hujus utrinque emar-

ginato, angulis lateralibus emarginationis productis plerumque acutis; scutello sat parvo, triangulari,

emarginato; tegminibus opacis longis, leviter ensatis, areis apicalibus quinque vel sex, discoidalibus

tribus; alis areis apicalibus quatuor, secunda haud stylata; pedibus sat robustis.

Oblong, subparallel, thickly and finely pubescent ; forehead broad, eyes very strongly prominent, subpetiolate,

ocelli about the same distance from one another as from the eyes; metopidium declivous; pronotum with-

out horns, but elevated and crowned with strong carine, which are more or less confluent and form blunt

lobes, shoulders very bluntly prominent; base of the pronotum emarginate on each side of the short

posterior process, lateral angles acute; scutellum small, triangular, emarginate ; tegmina opaque, slightly

ensiform, with five or six apical areas and three discoidal areas, the external areas declivous; wings with

four apical areas, the second not stylate; legs rather stout, with the anterior and intermediate tibice

slightly dilated.

The insects forming this genus are allied to Tolania, to the hornless specimens of

which they bear a superficial resemblance; they differ, however, apart from other

characters, in the presence of a pronotal process, which is wanting in Tolania.

Uroxiphus carye, Fitch*, of which there are specimens in the Oxford Museum

(apparently presented by Fitch himself), as well as in the British Museum, belongs to

this genus. The name Uroxiphus cannot be used in the present case, as it has

previously been employed by Amyot and Serville (1843) for a different genus of the

same family. |

1. Phaulocentrus pileatus, sp. n. (Tab. X. figg. 1, 1a.)

Of a greyish-testaceous colour, dull, finely pubescent, with the disc of the pronotum infuscate, and the base of

the tegmina obscurely lighter ; head with two distinct tubercles at the base; pronotum distinctly, but

not deeply, punctured, if viewed from the side strongly elevated and flat on the disc, if viewed from above

crowned with a strong almost circular carina, the space enclosed by which is divided by a longitudinal

carina continued on to the metopidium ; from the base of the pronotum proceeds a strongly arcuate short

process, which is testaceous behind and infuscate at the base, its apex lying between the emarginate

apices of the scutellum, the latter’ elongate triangular, and raised considerably towards the base ; tegmina

dull, pubescent, with brownish-testaceous veins, and with a fuscous spot behind the apex of the clavus;

legs and abdomen testaceous. _

Very closely allied to P. pileatus, and at first sight inseparable from it; the general colour, however, is more

uniform, the tubercles at the base of the head are smaller, the formation of the disc of the pronotum is

somewhat different, the space included by the carinzee being wider behind and more narrowed in front;

the posterior pronotal process is longer and almost straight, and not arcuate above the scutellum as in

that species, its extreme apex being dark, and the tegmina are obscurely lighter at the base.

Long. cum tegmn. 7 millim.; lat. int. hum. 23 millim.

Hab. GuateMAta, Cerro Zunil 4000 feet (Champion).

One female example. There is also in our collection a specimen with the abdomen

wanting, which is closely related to this species; it is, however, smaller and much

darker and more variegated, and has the raised disc of the pronotum somewhat

differently formed. When more specimens are obtained, it may possibly be found to be

the male of one of the species here described, but I believe it will prove to be distinct.

8. Phaulocentrus sordidus, sp.n. (Tab. X. figg. 8, 3a.)

P. proximo affinis, sed colore magis brunneo, tuberculis capitis vix distinctis, pronoto supra excavato et

fusco, emarginatione ad basin utrinque lata rectilineari ; tegminibus ad basin testaceo fuscoque variegatis,

pubescentibus, venis rufo-testaceis; corpore subtus pedibusque testaceis, his obscure variegatis.

Allied to P. proximus, but rather narrower and more darkly coloured, with the tubercles at the base of the

head very small, and the disc of the pronotum differently sculptured, the lateral carine being raised on

each side into a blunt lobe, and being slightly convergent behind ; the posterior process is almost straight

and the emarginations on each side of it are broader and squarer than in P. provimus; the tegmina have

a testaceous patch at the base, bordered broadly on each side with fuscous, the colour being more or less

obscure, and the apex of the clavus is testaceous, followed by a small fuscous patch on the corium, the

veins rufo-testaceous; legs and abdomen testaceous, the former very obscurely variegated.

Long. cum tegm. 7 millim. ; lat. int. hum. 24 millim.

Hab. Mexico, Soledad in Guerrero 5500 feet (H. H. Smith).

In the single example of this species received, a female, the tegmina have six apical

areas, but the first external area is small and perhaps abnormal, the regular number

for the genus being evidently five.

4. Phaulocentrus cornutus, sp.n. (Tab. X. figg. 4, 4a.)

P. proximo quoad staturam et colorem maxime affinis, sed pronoto antice duobus magnis latis cornibus

instructis, auriculatis, ad apicem late rotundatis, introrsum carinatis, processu postico testaceo, apice

nigro, leviter recurvato.

Of about the same size and colour as P. proximus, but easily distinguished by the pronotum being furnished

with two large porrect auriculate horns, which are broadly rounded at the apex, and are carinate on their

inner side; the pronotal process is testaceous, black at the apex, and if viewed from the side is curved,

and widened at the apex.

Very closely allied to Phaulocentrus, but distinguished by having the forehead more even, the frontal tubercles

very small, the eyes less prominent, and the pronotum without the ordinary central carina, and obtusely

produced above the metopidium; the teemina, moreover, have only two discoidal areas; the latter

character, however, is somewhat difficult to distinguish in these genera.

A single species from the State of Panama is referred to it.

1. Glischrocentrus cucullatus, sp. n. (Tab. X. figg. 5, 5a.)

Testaceous, dull, finely pubescent; head even, very finely punctured; pronotum, if viewed from above, quadri-

lateral, with the sides equal, broadest at the shoulders, produced behind into a straight process, on each

side of which the base is narrowly and roundly emarginate; if viewed from the side gradually raised from

the base to the front, where it is very obliquely produced above the metopidium ; scutellum level; tegmina

concolorous with the pronotum ; abdomen and legs testaceous, the tibiz in parts very obscurely darker.

Oblong, with the head broad between the eyes, which are very strongly prominent and almost entirely

exposed if viewed from above; ocelli nearer each other than to the eyes; pronotum with the shoulders

obliquely prominent, above which are two very large and broad, though not long, horns, which are trun-

cate at the apex and carinate above, and often notched on their upperside, thus presenting a short sharp

point at about the middle—they are, however, somewhat variable in size, direction, and shape; base of

the pronotum strongly excavated on each side of the posterior process, which is long, subparallel, and

acute, and reaches almost to the apex of the abdomen; scutellum about as broad as long, strongly

emarginate at the apex ; tegmina opaque, corium with five apical areas, which are more or less oblong

and subequal, and three discoidal areas, radial vein straight and uninterrupted, ulnar vein bifurcate

near the base and again at about the middle near the transverse vein of the third discoidal area; wings

with four apical and no discoidal areas ; abdomen cereous.

This genus in facies appears to be closely allied to Centruchus and Oxryrhachis, both

of which are peculiar to the Old World. Apart from other differences, it may be

prominent eyes, and from the latter by the extra discoidal area of the wings and the

shape of the pronotal process.

1. Centruchoides laticornis, sp. n. (Tab. X. figg. 6, 6a.)

Fuscus vel fusco-brunneus, pronoto sparsim breviter pubescenti, subrugoso, lineé centrali elevata, remotius

punctato, punctis magnis haud profundis; scutelli apice utrinque plerumque dilutiori ; tegminibus opacis,

maculis quibusdam parvis flavo-albescentibus interdum instructis; abdomine cereo vel cereo-tomentoso ;

pedibus ferrugineis, plus minusve infuscatis.

Of a fuscous or fuscous-brown colour, but variable, the lighter specimens having the head, the front of the

pronotum, and the base of the tegmina more or less testaceous, the darker specimens being almost

unicolorous ; pronotum with a very distinct central line, rugose at the sides, set with large and not very

closely placed punctures; scutellum usually lighter at its apical points; tegmina brown, with the veins

unicolorous, nearly always with a small dirty-whitish spot of pubescence just in the middle, and sometimes

with others towards the apex; these appear, however, to be very fugitive; abdomen covered with a

whitish or yellowish waxy-looking substance, the front parts pubescent; legs ferruginous, more or less

infuscate.

Long. cum tegm. 7-9 millim.; lat. int. corn. 4-5 millim.

Hab. Panama, Bugaba, Volcan de Chiriqui 2000 to 3000 feet (Champion).

The variation in the form of the horns of this species is probably not a sexual

character, as at first I thought might be the case: in one small specimen they are

notched in such a way as to be quite curved and pointed at the apex. The waxy

secretion on the abdomen appears to have as its foundation a whitish tomentose

pubescence. |

In facies this species strongly resembles Centruchus fuscipennis, Stal (= Centrotus

Suscipennis, Germ.), a South-African species.

SMERDALEA, gen. nov.

Robusta, scabra, fronte lata, angusté, ineequali, ad latera bilobaté, antennarum setis e lobis procedentibus,

sed acute prominulis ; pronoto pube recumbenti vestito, aspero, cornibus duobus anticis permagnis, latis,

serratulis, mucronibus quibusdam majoribus instructis, ante basin in processum magnum extenso; basi

pronoti truncata; processu elongato ad basin dilatato deinde tenuiori, et ad apicem iterum expanso,

quinque, discoidali una, suturé clavati perdistincta ; alis areis apicalibus quatuor, secunda haud stylata ;

pedibus teretibus, tibiis posticis extus utrinque minute serratulis.

A stout and rugged-looking species, the general form, if viewed from directly above, being that of an elongate

reversed isosceles triangle ; head produced in front, forehead broad and narrow, with the ocelli distinct,

situated nearer to one another than to the eyes ; above the ocelli are two or three small depressed shining

callosities, which in some lights resemble extra ocelli; eyes very strongly prominent, almost petiolate;

pronotum with the shoulders slightly but sharply prominent, with two very large and broad antlered horns

in front, which are rough and serrate; behind these and just before the base of the pronotum, which is

distinct and truncate, there is a long posterior process, which is considerably elevated above the scutellum,

dilated at the base, then narrowed, and strongly dilated and trispinose behind in the form of a reversed

bird’s-foot, the hinder spine being the longest; scutellum long, triangular, pointed at the apex, raised at

the base, then strongly sinuate, and again elevated at the apex into a strong broad protuberance, on which

the dilated apex of the pronotal process rests ; tegmina extending for some distance beyond the apex of

the pronotal process, uncovered, slightly sinuate on the interior margin at the apex of the clavus, and from

thence obliquely rounded to the apex, which is obtusely angled; clavus with two strong veins proceeding

from the base and a transverse vein in the middle; corium with the radial and ulnar veins straight until

about the middle and then curved, with five apical areas, one discoidal ; wings with four apical areas, the

second not stylate ; legs slender, posterior tibise with the outer side serratulate on the margins.

The species on which this genus is described is one of the most extraordinary

members of the Membracide that has yet been discovered. At first sight it looks like

a very large Cyphonia, but, as will be seen from the description, its affinities are

evidently towards the Centrotine, and it is very closely allied to Bocydium, near which

it must be located.

1. Smerdalea horrescens, sp. n. (Tab. X. figg. 7, 7a, b.)

Brunnea, testaceo fuscoque variegata ; pronoto scabro, flavo-pubescenti, fortiter remote et irregulariter punctato,

dimidia basali pubescenti, suturé clavi late hyaliné excepta, opaca, parte apicali hyalina; apice late fusco-

brunnea, venis crassis, hyalinis, pubescentibus; pedibus dilute testaceis, fusco annulatis.

Of a warm brown colour, variegated with fuscous and testaceous; pronotum irregularly and more or less

‘remotely punctured and more or less tuberculate, especially in front and on the broad frontal horns; on

each side of the base of the latter there is an uneven, smooth, testaceous callosity ; posterior process of the

pronotum testaceous in the middle, apical spines ringed with testaceous, the central spine being always

“ more or legs fuscous at the apex; tegmina variegated like the pronotum, but somewhat darker, with the

... basal half and the thick veins variegated and pubescent, and a broad patch at the apex and the portion

of the corium meeting the apex of the clavus fuscous-brown, the dark colour being uninterrupted along the

internal margin of the corium; legs light testaceous, the tibize ringed with fuscous.

| STYLOCENTRUS.

Stylocentrus, Stal, Kongl. Sv. Vet.-Ak. Handl. Band viii. 1, p. 49 (1869).

This genus was formed by Stal for the reception of Bocydium ancora, Perty, which

is found in Cayenne, and is, apparently, a very scarce species. It may be known by

the very long and slender trispinose process which proceeds from the front of the

pronotum (the intermediate spine almost reaching to the apex of the tegmina), and by

the double tubercles on this part. The insect described below is not so large or hand-

some as B. ancora, but it is one of the most remarkable of the Central-American

Homoptera: Mr. Champion informs me that it is very scarce, and that he very rarely

found it, and then only a single specimen at a time.

Niger, capite, metopidio et lateribus pectoris squamis albis maculato, et lineé utrinque pronoti albo-squamosé ;

oculis valde prominulis ; pronoto haud nitido, remotius punctato, lined centrali elevata, processu trispinoso

gracillimo, spina intermedia fere ad apicem tegminum producto; scutello brevi, apice acuto; tegminibus

pellucidis venis nigris, quibusdam latis; abdomine rufo, apice fusco; pedibus nigris, tarsis tibiarumque

Black, dull, with the head and front parts of the pronotum furnished with more or less distinct patches of

white scales, which are present in two broad lines on each side of the pronotum, these lines almost meeting

beneath the base of the trispinal process, where they are separated by a narrow line; the sides of the

chest also, which is dark, are furnished with large patches of similar white scales; the trispinose process

is very long and slender; the pronotum is distinctly but somewhat remotely punctured, as is also the

scutellum, which is very short and terminates in a short sharp point; the tegmina are transparent, with

dark veins, some of which are broad and thick; the clavus and external part of the corium are rather

strongly punctured, especially towards the base, and the claval margin is somewhat thickened, with the

dark colour tapering to the apex, so that the scutellum appears to be elongate until the tegmina are

divided ; abdomen red, with the apex fuscous; legs black, with the tarsi and the apex of the tibie yellow.

LYCODERES.

Lycoderes, Germar, Rev. Ent. Silb. iii. p. 259 (1835); Stal, Kongl. Vet.-Ak. Handl. Band viii.

1, p. 52 (1869). |

The two species below described evidently belong to Lycoderes, Germ., but they

differ from the normal members of the genus in having the scutellum concealed. Some

of the species, of which there are a considerable number (mostly from Brazil), are

among the most extraordinary of the Membracide. The genus Stegaspis is closely

allied to Lycoderes, but the pronotum is more foliaceous in front and is never lobed at

the apex.

Stal (/. c. p. 53) has divided Lycoderes into several subgenera on the formation of

the pronotum and the areas of the tegmina.

1, Lycoderes phasianus, sp.n. (Tab. X. figg. 9, 9a.)

Elongatus, brunneo-ferrugineus, unicolor, supra visus angustatus maxime compressus, a latere visus ampliatus,

ab apice tegminum usque ad basin cornus pronoti leviter et equaliter rotundato, hoc porrecto, haud

longo, parallelo, apice bilobato ; pronoto acute carinato, fortiter et rugose, sed varie, punctato, apice postico

obtuso apicem clavi vix superante ; scutello obtecto; tegminibus cum pronoto concoloribus, opacis, ad

basin fortiter punctatis ; abdomine pedibusque testaceis.

Much compressed, of a unicolorous ferruginous-brown colour, very narrow if viewed from above, if viewed

from the side broad and evenly rounded from the apex of the tegmina to the base of the pronotal horn ;

the latter is comparatively short, porrect and elevated, rugose at the sides, and bilobed at the apex; the

pronotum is strongly punctured, but more closely at the shoulders than on the sides, on which are present

several rugose raised lines ; the apex just reaches the apex of the clavus ; scutellum concealed ; tegmina

dark, opaque, punctured strongly at the base; abdomen and legs clear yellow-testaceous.

Long. cum tegm. 9 millim.; lat. int. hum. 17-2 millim.

Hab. Panama, Bugaba (Champion).

LYCODERES.—GERRIDIUS. 165

This species appears in some points to be allied to L. ductans, Stal, but, to judge

from the description, it is evidently quite distinct on account of the formation of the

pronotum above the scutellum.

2. Lycoderes serraticornis, sp.n. (Tab. X. figg. 10, 10 a.)

Griseo-testaceus, capite sat magno, oculis prominulis; pronoto sat fortiter, sed haud profunde punctato,

antice in cornu magnum, porrectum, parallelum, utrinque plus minusve distincte unicarinatum, lateribus

sparsim serratulis, apice bilobato, productum, processu postico angusto longo fere recto apicem clavi vix

tangente ; scutello obtecto; tegminibus pone processum posticum oblique ad apicem truncatis, hyalinis,

venis testaceo-brunneis, vix parte tertid opaca fortiter punctaté; pedibus abdomineque testaceis vel plus

minusyve nigricantibus.

Broader in proportion than the preceding, of a griseous-testaceous colour, with the centre of the head and

sometimes the hinder parts of the dorsum obscurely fuscous; pronotum produced in front into a long

and stout, porrect, and very slightly deflexed horn, which is distinctly though sparingly serrate at the

sides and bilobed at the apex ; the sculpture of the horn and for the most part of the pronotum is rugose,

but not deep; the posterior process is long and almost straight and reaches just to the apex of the clavus,

from which point the tegmina are obliquely truncate to their extreme apical angle, which is obtusely

rounded in a broad angle ; the tegmina are hyaline-brown, opaque and punctured at the base, with the

veins testaceous-brown, and the apex irrorated with ferruginous dots; legs and abdomen testaceous, often

more or less infuscate ; the bodies of several specimens are more or less sprinkled with a white secretion.

Long. cum tegm. 9 millim.; lat. int. hum. 2 millim.

Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion).

Several specimens. In our collection there is a broken specimen of another species,

also from Bugaba, which is apparently closely allied to the one just described, with the

tegmina more punctured and the posterior process of the pronotum differently shaped ;

the anterior horn, however, is broken off.

Oblong, subparallel ; head large, triangularly produced in front; ocelli situated on a line drawn through the

centre of the eyes, evidently more distant from each other than from the eyes ; pronotum simple, without

horns or prominences, broadest a little before the base, which is very gently rounded, very gradually

declivous, with the broad posterior margin of the front of the head covering the apex of the metopidium ;

scutellum very large, triangular, furnished with a large upright protuberance behind, which in front is

declivous and has its hinder margin straight at right angles to the dorsum ; tegmina tectiform behind the

scutellum, very smooth and shining, with five apical and two discoidal areas, which are for the most part

oblong and have the veins running parallel to the margins ; wings with four apical areas, the second being

oblong and not stylate ; posterior legs elongate, with the tarsi very long, recurved.

This genus appears to be closely related to Lamproptera in certain points, but differs

in having the head and pronotum simple, without horns, and in the formation of the

external apical areas of the tegmina, which are not deflexed.

This is one of the transitional genera of the Membracide, in which the pronotum

has no posterior process; it is, however, in all other respects a true Centrotid, and the

species were assigned to the genus Centrotus, until Stal characterized the genus.

There is a series of about forty specimens of this species in our collection; they vary

very much in size and in the development of the pronotal horns, which are occasionally

wanting or only partially developed. The difference in the form of the horn is not

a sexual character. We figure a typical specimen from Sinanja and a variety from the

Volcan de Chiriqui, bdth females.

elongate, broadly rounded, and more punctured behind; the areas of the tegmina are somewhat variable

Although this insect appears to be distinct from 7. opponens, yet I have separated it

with great hesitation, owing to the extreme variability of the specimens of the genus

which I have hitherto seen. The character, however, of the scutellum, which is a

prominent feature in the genus, seems to be constant.

GARGAROPSIS, gen. nov.

Brevis, oblonga sat lata, capite longitudine paullo latiore, ocellis indistinctis, inter se quam ab oculis remotiori-

bus; pronoto lato, mox ante basin obtuse angulato latissimo, humeris rotundatis, sine cornibus vel

processu postico, basi supra scutellum truncata, vix sinuaté ; scutello magno, equilatero-triangulari, apice

producto acuto, mox post medium linea semicirculari impresso ; tegminibus totis intectis, hyalinis, vitreis,

nitidis, remote fortiter punctatis, nervis corii indistinctis, ad medium evanescentibus, corio areis apicalibus

quatuor, discoidalibus nullis vel vix indicatis, alis areis apicalibus tribus ; pedibus posticis longis, robustis,

tibiis externe utrinque distincte serratulis, setosis; pedibus anticis et intermediis brevioribus fere sim-

plicibus.

Oblong and rather broad, gently narrowed behind; ocelli indistinct, situated on a line drawn just between the

centre of the eyes, to which they are closer than to one another ; pronotum in front of about the breadth —

of the head, gradually widened towards the base, obliquely angled a little before the base and there

broadest, the shoulders rounded; horns and posterior process entirely absent ; scutellum large, with its

three sides about equal, acute at the apex; tegmina entirely uncovered, large, vitreous, with coarse

remote punctuation, which is stronger on the clavus, corium with the radial and ulnar veins marked

but indistinct, and with four apical areas, clavus large with the veins more distinct; wings with three

apical areas, and with the reflexed portion (answering to clavus) very large and furnished with two large

thick veins, which cut one another in the centre; posterior legs long and stout, tibie rather strongly

serratulate on their outer margins, anterior and intermediate pairs rather short and simple.

This is one of the puzzling genera which appear to be rightly placed at the end of

the Centrotine, and which, on the other hand, scarcely appear to be true Membracide.

The present genus is very distinct from any other described, and does not appear

to have any striking affinities. Very little, however, is known as yet about these

transitional genera, as they appear to have been found very rarely, and one or two

specimens at a time; they can therefore be only located provisionally at present. The

position of the ocelli and the simple vertex of the head, as well as the formation of the

tegmina, separate Gargaropsis very widely from Tropidaspis and Endoiastus. In:

general facies it resembles a broad species of Gargara, though the resemblance is, of

course, entirely superficial.

1. Gargaropsis innervis, sp.n. (Tab. X. fig. 15.)

Rather broad, gradually narrowed behind, with the head finely granulose, testaceous, with minute black spots

and two lighter testaceous small patches at the base; pronotum and scutellum obscurely testaceous,

irrorated with black, the pronotum with obscure warm brown markings at the sides, metopidium with

two testaceous patches in front; semicircular depression before the apex of the scutelum (which is black)

very distinct; tegmina vitreous, smoky at the apex and on the extreme margins, with the punctures

dark ; posterior legs mostly black, anterior pairs fusco-testaceous ; abdomen black, with the apex of the

segments testaceous.

One male specimen. The male organs, to judge by their external appearance, may

present good characters, but would require dissection. In examining the specimen,

the pronotum became detached, leaving asmooth space exposed underneath, at the base

of which are markings, which under a compound microscope appear in some lights as if

they might be a stridulating-organ.

ENDOTASTUS, gen. nov.

Oblongus, parvus, subparallelus, capite magno, producto, ad basin depressione lata in duo lobos divisd, antennis

sub oculis positis, ocellis fere ad marginen centralem oculorum sitis, his approximatis ; pronoto irregulariter

- Oblong, narrowed in front and parallel behind, with the head large and produced, and bilobed at the base,

above which the metopidium is strongly plicate; ocelli placed close to the eyes at about their central

margin; pronotum irregularly hexagonal, with the angles more or less rounded, strongly convex if viewed

from the side, with a very distinct central keel, but without horns or posterior process; shoulders very

bluntly prominent if viewed from the front, rounded if viewed from above, the base almost straight before

the scutellum. which is about as long as broad, pointed at the apex and plainly carinate ; tegmina opaque

and punctured, corium with four apical areas and no discoidal; wings with four apical areas; tarsi rather

short.

The formation of the basal portion of the head and the position of the ocelli appear

to place this peculiar little Membracid near Zropidaspis and one or two allied genera;

it is quite possible, however, that future writers may assign it a different position.

Tropidaspis, Stal, Kongl, Sv. Vet.-Ak. Hand]. Band viii. 1, p. 56 (1869).

I have not seen the type of this genus [which was formed by Stal for the reception

of Centrotus carinatus, Fabr. (Syst. Rhyngot. p. 21)], and Dr. Aurivillius informs me

that it is not represented in the Stockholm Museum. St&l’s description, however, is

very full, and the insect described below agrees exactly with it, except that he lays

stress upon the fact that the corium has no discoidal areas, whereas the Panama

example has two small ones on one side and one on the other. This very fact shows

that the venation in this example is abnormal ; and as in other respects I shall have to

copy Stal’s description almost word for word, I have not much doubt in referring our

insect to this genus. The chief characters appear to be the close approximation of the

ocelli to the eyes, the raised base of the head, the absence of the pronotal process, and

the long scutellum, which is strongly carinate behind.

longitudinal smooth testaceous line; pronotum transverse, broadest about the base, basal margin about

twice as broad as the apical margin, rather strongly sinuate before the scutellum, ferruginous, obscurely

variegated with fuscous in front, and with the apical part of the produced lobe near the eyes testaceous ;

scutellum fuscous, large and long, convex in front and acutely keeled throughout, with a testaceous band

The position of this subfamily, which is here regarded as containing the genus

Aithalion only, has given rise to much difference of opinion among authors, and has

been very differently located *. Germar (Mag. der Ent. iv. p. 94) places 4ithalion

between Hupelix and Cicada; Amyot and Serville (Hist. Nat. Ins. Hémipt. p. 556)

place it under the Cicadellina of Burmeister, among the group Eurymelides, and

Walker (List of Homopt. Ins. iii. p. 646) follows the same arrangement ; Stal (Kongl.

Sv. Vet.-Ak. Handl. Band viii. 1, p. 49) includes it under his Centrotida, which,

however, he regards as merely a subfamily of his Jassida; while Ashmead (Ent.

Americana, v. p. 125) makes Athalion and Hurymela the types of separate subfamilies

(AEthalionine and Eurymeline) of the Bythoscopide.

Aithalion has evidently strong affinities towards Tolania, but differs from it in too

great a degree to admit of being classed in the same subfamily with the latter genus,

an arrangement adopted by Goding (Trans. Am. Ent. Soc. xix. p. 253), and, if it must be

definitely located, it is, perhaps, most correctly placed near or among the Centrotine.

At the same time it differs from the rest of the Membracide, and if included under

that family it becomes almost impossible to give a definition that will comprise all its

members, for it neither has a pronotal process nor a perpendicularly declivous meto-

pidium; nor does it altogether agree with the Jasside, and still less with the

Bythoscopide, under both of which it has been located, In fact, Athalion is plainly

a transitional genus and as such must be regarded; as, however, its affinities seem, if

anything, to lean towards the Membracide, it is perhaps the best plan to provisionally

include it under that family, though there appears to be no reason why it should not

be placed under a separate family. In all zoological classification there seems too

great a tendency on the one hand to force transitional genera under fixed families, and

on the other to limit too closely the formation of new families and groups. In nearly

all cases the family or group at its extreme end must be subject to exceptions, and must

be more or less elastic. Stal is much blamed in certain quarters for too often using the

words “ plerumque,”. *‘ seepissime,” “‘ rarissime,” &c. to qualify his definitions ; perhaps

this is true to a certain extent, but it is difficult to see how he could have done other-

wise in the case of the Homoptera, in the present state of our knowledge, and

considering the very small available material that has hitherto been got together by

collectors.

This genus contains upwards of twenty species, all from Tropical South America ;

some of these, however, are very closely related and are apparently synonymous. They

are of oblong form, with prominent eyes, which project plainly beyond the sides of the

metopidium, and with a convex and transversely hexagonal pronotum, which is rounded

at the base; the elytra are more or less strongly reticulate, with the veins strong and

raised; and the legs are usually banded with black or fuscous.

This is a very distinct, dull brownish species, which may at once be known by the

dark spots on the testaceous veins of the tegmina, the head and pronotum being

similarly spotted.

Allied rather closely to the type-form, but of a more griseous colour, with the posterior margin of the head

more sinuate in the middle, the pronotum a little shorter in proportion and more declivous, and the veins

of the tegmina less distinctly marked with fuscous (this, however, is a variable character); the base of

the tegmina is less broadly opaque and punctured.

Oblong, subparallel, of a griseo-testaceous colour, with the head narrow, slightly but plainly sinuate on its

posterior margin ; pronotum and scutellum without spots, the former distinctly and moderately strongly,

and the latter very finely, punctured; tegmina punctured at the base, with the veins very distinct and

raised, and the apical areas more regular and quadrate than in the allied species ; legs dark testaceous,

in part obscurely infuscate. —

This seems to be a very distinct species, although it is allied to the var. minor of

LE. nervoso-punctatum ; in both these insects the pronotum is more declivous in front

than appears to be usual with members of the group, and thus causes them to approach

nearer to the true Membracide. The specimens described are females.

which there is a single example in the British Museum; but I find since that Stal

himself has noticed it (Ofv. Kongl. Vet.-Ak. Férh. 1869, p. 299).

ADDENDUM.

Among a few insects received after the completion of the MSS. of the Membracide

was one which seemed at first to belong to the later Centrotine, as it resembled one or

two of these in general appearance; the very short posterior tarsi, however, and the

venation of the tegmina, at once showed that it belonged to the Hoplophorine. I

include it under Ochropepla (anted, p. 48), although in some points it differs from that

genus; it has the fourth apical wing-cell only just indicated.

Fam. CERCOPID *.

Ranatre, Germar, Mag. Ent. iv. p. 34 (1821) (pars).

Cercopides, Amyot et Serville, Hist. Nat. des Ins. Hémipt. p. 558 (1848).

Cercopida, Stal, Hem. Afr. iv. p. 54 (1865).

The generally recognized characters of this family are as follows :—-Front convex, or

produced and compressed on either side; ocelli two, situated on the vertex and near its

base ; pronotum large, hexagonal or trapezoidal, with a notch on its posterior margin ;

tegmina nearly always coriaceous; scutellum small or medium-sized, triangular ; legs

remote from the sides of the body, with the coxe, especially the posterior pair, short,

and the tibie cylindrical, the hind pair being furnished with two (rarely one) strong

spines on the outer side and a ring of spinules round the apex ; the two basal joints of

the tarsi denticulate at the apex.

The family may be roughly subdivided as follows :—

Anterior margin of the pronotum straight; eyes as long as broad . . . . . CERCOPINE.

Anterior margin of the pronotum rounded and produced between the eyes,

which are nearly always more or less transverset. . . . . . . . © P9ryELina.

Subfam. CERCOPINAL.

Subf. Cercopida, Stal, Hem. Afr. iv. p. 55.

The limits of this subfamily are very doubtful. The genus Cercopis, as understood

by Fabricius, has almost a world-wide range, as pointed out by Distant (Trans. Ent.

Soc. Lond. 1878, p. 173). In 1843 Cercopis was subdivided into six genera by Amyot

and Serville, who restricted the genus Tomaspis to species from South and Central

America. In 1866 Stal sunk three of Amyot and Serville’s genera, Triecphora, Monec-

phora, and Sphenorhina, and placed them all under Tomaspis, thus extending the range

of the latter genus to the Old as well as the New World. Distant (/. ¢. p. 178) agrees

with Stal in suppressing T’riecphora and Monecphora, but prefers to retain Sphenorhina,

on the ground that it seems so well-marked a genus, and one so easily recognized, that

it is at least convenient to retain it. The sole distinction, however, of Sphenorhina, as

given by Amyot and Serville, is that it has the front laterally compressed, ‘‘ avec une

forte caréne en forme de coin plus ou moins aigu et dilaté” (Hémiptéres, p. 562) ;

whereas in Monecphora it is not compressed and has only a feeble carina, and in

Triecphora it is furnished with three raised lines or carine, which, according to Amyot

* The Cercopide are placed after the Membracide for convenience’ sake, and not from any desire to

indicate that this is necessarily their proper position; the classification of the Homoptera is as yet quite

‘unsettled. .

Tt There are one or two (probably more) intermediate forms which appear to render any division of the

family more or less unsatisfactory, but, as a rule, the facies of the two groups is unmistakable.

‘TOMASPIS. . 175

and Serville themselves, are by no means always visible. -At best, the character given

for Sphenorhina is a weak one, generically, and besides this, on examining a large

number of species, I have found that it is often more or less feebly marked, and that

intermediate examples occur, which make it practically impossible to draw a hard-and-

fast line between Amyot and Serville’s genera: the facies of the various species, as well

as their size, differs very considerably, some being elongate and parallel, and others

short and ovate; the shape, however, is by no means associated with the carination and

compression of the front, for the species most similar in appearance differ in this point *.

Under all the circumstances, then, it seems best to include all our species, at all events

provisionally, under Tomaspis.

TOMASPIS.

Tomaspis, Amyot et Serville, Hist. Nat. des Ins. Hémipt. p. 560 (1843).

Triecphora, Amyot et Serville, loc. cit. p. 561.

Monecphora, Amyot et Serville, loc. cit. p. 562.

Sphenorhina, Amyot et Serville, loc. cit. p. 562.

This genus, as here constituted, includes a large number of species, both from the

Old and the New World. Amyot and Serville restricted Tomaspis to insects from

South and Central America; but, for the reasons already given, I prefer to follow Stal

in again extending it. The genus differs from Cercopis in having the ocelli usually

very close together, and always nearer to one another than to the eyes, whereas in

Cercopis they are equidistant from one another and from the eyes, or are closer to the

eyes than to each other.

The species described or enumerated below may be divided into four sections as

- follows; but they are merely provisional, and it must be allowed that certain of the

species are intermediate :—

1. Larger species, 17-19 millim. in length, ovate or broad-oblong in shape; with the tegmina,

as a rule, coloured in transverse bands, but sometimes spotted or unicolorous.

2. Intermediate-sized species, 14-16 millim. in length, subparallel in shape; with the tegmina

coloured in transverse bands.

8. Smaller species, 5-12} millim. in length, ovate or oblong-ovate, rarely oblong in shape ;

with the tegmina, as a rule, coloured in transverse bands, rarely spotted or unicolorous.

4, Moderate-sized species, 7-12 or 13 millim. in length, elongate-oblong or parallel in shape ;

with the tegmina coloured in more or less distinct longitudinal bands or markings, very

rarely spotted +.

In the Cercopine the apical portion of the tegmina is nearly always more or less

* A glance at Tab. XI., where the metopidium of each species is separately figured, will at once make these

points clear.

t The only exception I know is the variety of 7. imperans described below, in which the red marginal:

longitudinal band is broken into spots.

176 HEMIPTERA-HOMOPTERA.

distinctly rugosely reticulated: in Group 1 this character is very strongly marked; in

Group 2 it is very slight; in Group 3 it varies, being sometimes strong and sometimes

nearly absent; in Group 4 it is not strong, though usually distinctly traceable.

The length is given from the front of the head to the apex of the tegmina folded ;

the length of the body, as given by some authors, is very deceptive, as the segments of

the abdomen shrivel and run up very considerably in dried specimens.

Group 1.

This group includes several fine and handsome species, the commonest apparently

being the red-banded Tomaspis inca, which seems to be plentiful in Mexico, but to be

found rarely in the adjacent countries.

In this species the sides of the pronotum are usually narrowly, but sometimes very

broadly, red, and striking varieties occasionally occur. In the Vienna Museum there

is a variety with the tegmina, except at the apex and base, unicolorous crimson-scarlet,

and also three examples which are almost entirely black, with only faint indications of

the usual red bands on the tegmina. A specimen from Mescala, Guerrero, and a variety

from Mexico, in the Vienna Museum collection, are figured.

A large, subovate species, with the front parts greenish-eneous, shining; metopidium compressed and |

produced, with a reddish carina; pronotum at its widest part rather broader than long, rugosely punc-

tured, the anterior margin red; tegmina dull, very closely sculptured, with the apical third reticulate-

rugose, the basal third somewhat irregularly flavo-testaceous ; immediately behind this there are two

yellow spots, one on each tegmina, almost confluent with the basal colour, and at some distance behind

these there are four distinct spots, two on each tegmen, in a row, the two side ones touching the margins,

Group 2.

This group might perhaps be included under the preceding ; the species referred to

it, however, are smaller, and 7. mylabroides and T. preminiata are very distinct in

general appearance.

Rather broad, black, with the metopidium (which is scarcely produced), the base of the pronotum, shoulders,

and two straight and rather narrow bands (one at and one behind the middle) obscurely luteous ; pronotum

shining, broader than long, somewhat remotely and shallowly punctured; tegmina rather strongly

punctured and shining in front, thickly punctured and duller behind, very slightly rugose at the apex ;

underside and legs pitchy.

Long, 14 millim.; lat. 8 millim.

Hab. Panama, Bugaba (Champion).

_ A somewhat unsatisfactory and intermediate species, with an affinity towards T. inca,

and yet resembling certain members of Group 8. It would be classed as a Monecphora,

but the metopidium is slightly produced, though not compressed.

8. Tomaspis mylabroides, sp.n. (Tab. XI. figg. 7, 7a.)

Elongata, parallela, capite antice flavo, postice cum lateribus ante oculos antennarumque basi nigris; pronoto

A moderately elongate, parallel species, with the head black at the sides and at the base, and yellow in front ;

metopidium slightly compressed and produced; pronotum smooth and shining, the apical third in front

yellow, the rest black, the division being usually abruptly marked, the punctuation somewhat remote and

shallow; scutellum yellow, except at the apex; tegmina black, with the front part and a broad fascia at

the middle yellow, very closely punctured, especially behind, the apex very slightly reticulate; underside

reddish-yellow in front; abdomen black; legs black or pitchy, the femora entirely or almost entirely

reddish-yellow.

Long. 153 millim.; lat. 8 millim.

Very like the preceding, but with the whole head and pronotum, as well as the scutellum (except the extreme

point), humeral portion, and central fascia of the tegmina, and the underside of the body, except the

abdomen, bright scarlet ; the femora, with the exception of the apex of the anterior and posterior pairs,

are also scarlet.

Long. 153 millim.; lat. 8 millim.

Hab. Panama, Bugaba (Champion).

This may eventually turn out to be a form of 7. mylabroides.

Group 3.

This group includes a large number of moderate or small-sized species, mostly of ovate

shape; the colour varies somewhat, but is usually in transverse bands. So far as I have

seen, the bulk of the American species of Cercopine belong to this group, some of

them being very abundant.

10. Tomaspis limbata, sp.n. (Lab. XI. figg. 9, 9a.)

Ovata, parum nitida, nigra, metopidio producto; pronoto latitudine sesquilongiori, sat fortiter rugoso-punctato,

omnibus anguste miniatis ; corpore subtus pedibusque piceis, metasterno interdum rufescenti.

A moderate and somewhat variably-sized insect, black, with the posterior and lateral margins of the pronotum

and all the margins of the tegmina, except occasionally near the scutellum, narrowly scarlet; sculpture

of the pronotum rather strong, very close, that of the tegmina very dense and fine, the apex of the latter

very slightly reticulate ; underside and legs pitchy, the metasternum reddish.

Long. 123 millim.; lat. 6 millim.

Hab. Mexico (Signoret, in Mus. Vind. Cas.; Mus. Brit.); Guatemaua, Purula in

Vera Paz (Champion).

One of Signoret’s specimens is larger and has the posterior border of the pronotum

more broadly scarlet, while a second has only the basal margin of the pronotum scarlet.

The name “‘limbata” is a MS. name of Signoret’s attached to the last-mentioned

specimen. An example from Purula is figured.

11. Tomaspis discontinua, sp. n. (Tab. XI. figg. 10, 10a.)

Oblongo-ovata, parum nitida, nigra, metopidio producto; pronoto basi lateribusque late flavescentibus, latitudine

sesquilongiori, dense rugoso-punctato; scutello nigro flavo-marginato; tegminibus nigris, limbo sat lato

ab humeris ad medium vel usque ad tertiam partem apicalem vix rugosam extenso; corpore subtus antice

nigro, metasterno abdomineque flavescentibus ; pedibus piceis.

Variat colore rufo vel rufo-flavescenti.

Oblong-ovate, dull, very closely sculptured, black, with the posterior and lateral margins of the pronotum, the

margins of the scutellum, and a rather broad border at the margin of the tegmina yellow or red; the

tegminal border ceases at the middle, or reaches further towards the apex, but always ceases at some

distance from the apex; the colour of the pronotum is somewhat variable, the coloured margins being

broader or narrower; metasternum and abdomen yellow or red; legs pitchy.

Long. 94 millim.; lat. 5 millim.

A fair series.

Monecphora inferens, Walk. loc. cit., Suppl. p. 176 (1858) *.

Hab. Norta America, Georgia?.—Mexico (Sallé?; Bilimek and Sichel, in Mus.

Tabasco (H. H. Smith); Brrttsq Honpuras, R. Sarstoon (Blancaneaux); GUATEMALA,

Cerro Zunil (Champion); Costa Rica (Van Patten).—ANTILLES, Cuba and Jamaica

(Signoret, in Mus. Vind. Ces.).

I believe that the above synonymy is correct. In the typical 7. bifascia the trans-

verse bands on the pronotum and tegmina are broader than in 7. angusta, and in

TL. inferens the bands on the tegmina tend to break up and disappear, and occasionally

only a reddish band on the pronotum is left; in all the varieties, however, the longi-

tudinal band across the middle of the pronotum is distinct. In one specimen from

Ciudad in Durango the hinder tegminal band is distinct, and the front one is absent.

No locality is given by Walker! for his M. bifascia.

There are several examples in our collection which I have doubtfully referred to this

species, which is evidently variable; they are more ovate than the usual form of

T. bifascia (which is, as a rule, oblong, although short-ovate specimens occur), and

have the bands on the tegmina whitish and more obscure; the characteristic line,

however, across the middle of the pronotum is always present. It is possible that one

specimen from El Reposo, Guatemala (Champion), may prove distinct; but it can

hardly be described unless more are discovered, and, at best, it would be a doubtful

species.

13. Tomaspis vilior, sp.n. (Tab. XI. figg. 11, 11a.)

Ovalis, picea, unicolor, capite pronotoque leviter metallicis, illo metopidio haud producto, hoc sat nitido,

pedibus piceis vel fusco-testaceis.

Oval or suboblong, of a unicolorous pitchy colour, with very faint traces of four lighter spots at the margins

of the tegmina, which are scarcely apparent unless the insect is examined closely ; head and pronotum

shining, the former rather deeply excavate on the vertex, the latter closely and rugosely sculptured, with

several strong impressions in front; scutellum broad in front, produced into a long point behind, trans-

versely and strongly rugose; tegmina very finely sculptured, very finely pubescent, the apex rugosely

reticulate, but not strongly; legs fusco-testaceous, in part pitchy.

Long. 9 millim.; lat. max. 5 millim.

Hab. Panama, Bugaba, Volcan de Chiriqui 2500 to 8000 feet (Champion).

This species is allied to Sphenorhina simplex, Walk. (Insecta Saundersiana, Homopt.

p. 90), from Colombia, but, according to the old division, it belongs to a different genus.

The specimens from Bugaba are somewhat more oblong than those from the Volcan

de Chiriqui, and among them are two with traces of distinct rows of spots on the

tegmina; it is possible that they may belong to another species, but I cannot satis-

factorily separate them. An example from the Volcan de Chiriqui is figured.

14. Tomaspis ignobilis, sp. n.

T. viltori affinis, sed multo minor, sculptura crassiori; parva, nigra, sat nitida, metopidio haud producto ;

pronoto fortiter rugoso, linea centrali distincte elevaté; tegminibus dense sat fortiter subrugoso-punctatis,

apicibus haud reticulatis, vita albida sat lata ad marginem pone medium, maculaque parva obscure albida

in eddem linea prope suturam posité utrinque instructis ; corpore subtus fusco, pedibus piceo-testaceis.

A small and inconspicuous, but distinct species; black, rather shining; head moderately large, with the

metopidium not produced; pronotum nearly twice as broad as long, coarsely and rugosely sculptured,

with a strongly raised central line, on each side of which is a depression; scutellum much less coarsely

punctured than the pronotum; tegmina strongly punctured, with hardly a trace of rugose reticulation at

the apex, with a rather broad whitish horizontal band behind the middle reaching from the margin to

near the middle, and a small obscure whitish spot (sometimes hardly traceable) between this and the

suture; underside fuscous; legs pitchy-testaceous.

Long. 64 millim.; lat. max. 3 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

Tomaspis sepulchralis, Stal, Stett. ent. Zeit. xxv. p. 65 (1864) °.

Hab. Mexico! (Mus. Vind. Ces. ; Mus. Oxon.).

Stal’s description! is as follows :—* Pubescens, nigricans, nitida; margine angusto

basali thoracis basique ipsa tegminum sanguineis.” In one of the specimens referred

to from the Vienna Museum the lateral margins of the pronotum are red, as well as

the basal margin, while in the Oxford Museum specimen the shoulders only are slightly

red, and the pronotum is entirely black.

The species is not represented in our collection. I have seen three specimens of it,

all males, including the one in the Oxford Museum.

Oblong-ovate, very finely pubescent; head red, the vertex in part black; metopidium produced; pronotum

dark, with an neous reflection, rugosely punctate, the sides rather broadly red; tegmina very closely

and finely punctured, dull, scarlet, with a broad band at the middle and the apical third black; femora

pitchy, the tibize and tarsi mostly rufo-testaceous.

Long. 11 millim.; lat. max. 54 millim.

Hab. Panama, Volcan de Chiriqui 8000 feet (Champion).

This is a very handsome and distinct species. On remounting the single specimen

received I found an Acarid (apparently a Gamasus) which had evidently been attached

to it; I have not before noticed that any homopterous insects have been attacked

by Acari.

18. Tomaspis handlirschi, sp. n. (Tab. XI. figg. 13, 13 a.)

Oblongo-ovata, brunneo-rufa; capite unicolori, metopidio peracute producto ; pronoto margine anteriori quatuor

Of a brownish-red colour, with four spots on the margin of the pronotum (two at the angles and two in the

middle) yellow, and the posterior margin orange, and with ten orange spots on the tegmina—six in front

of and four behind the middle, arranged in two transverse lines; pronotum distinctly punctured, rather

shiny; scutellum comparatively small; tegmina very finely sculptured, dull; abdomen and breast red;

legs pitchy-red.

Long. 12 millim.; lat. max. 6 millim.

Hab. CentraL America (Mus. Vind. Ces.).

One specimen, labelled “ Friedth. 839.” This is a very distinct and unmistakable

species, although it is possible that, when more are discovered, the ground-colour will

be found to be somewhat darker. I have named this insect after Herr Handlirsch, of

the Vienna Museum, who has kindly assisted me in sending specimens for examination.

Head, pronotum, and scutellum unicolorous, with metallic reflections; pronotum dull, closely and rather

strongly rugose; tegmina very dark blue, almost black, with the interior basal margin and two bands

scarlet ; the scarlet basal margin forms a V-shaped mark bounding the posterior margins of the pronotum

and the scutellum, the hinder part of which meets the first band at the suture; this band is slightly

waved just before the margins, where it is thickened; the hinder band is curved very slightly towards

the apex, which is plainly reticulate; abdomen and breast red; legs pitchy, the posterior femora and

tibiee rufescent.

Long. 10 millim.; lat. max. 5 millim.

There are two specimens in the Vienna Museum standing under the MS. name

of Sphenorhina levicollis, Signoret: one, labelled as from New Granada, is slightly

other, from Guatemala, has the pronotum dull and rugose, and it is from this that I

have described the species.

the tegmina are either red or yellow. There is a single specimen from Guatemala

in the Vienna Museum belonging to the same form, with the bands red, labelled

Sphenorhina trifasciata, Signoret, in litt. I have only seen one example of the typical

T. sororia from Central America, although it appears to be the most abundant of the

Cercopide in the northern districts of South America; it has the head, pronotum, and

scutellum entirely red, and the tegmina black, with two broad yellow bands. The

form in our collection appears to replace it further north, and is no doubt identical with

Cercopis bicincta, Say. Of this insect, Say says that it “resembles the rubra, Linn.,

and sororia, Germ., but is sufficiently distinct”; the difference, however, only appears

to be one of colour, and the species is evidently variable in this respect.

In the Vienna Museum collection are four specimens named Sphenorhina tricolor,

Signoret, in litt., which only differ in having the base of the tegmina yellow (unicolorous

with the front band), and two named S. flavicincta, Signoret, in litt., which have the

hinder band wanting; they are, however, only varieties of the typical sororia form, and

serve to show how it varies in colour. Some of the same varieties may be seen in the

British Museum collection. ‘Two forms from the Volcan de Chiriqui are figured. |

Rather long, oblong-ovate, of a dark castaneous or rufous-brown colour, with two abrupt whitish spots on the

tegmina behind the shoulders, which are elongate and scarcely touch the margin, a very thin line of

darker colour separating them from it, except just at the base; head rather large, with the metopidium

rounded, not compressed or produced; pronotum rugosely and-ather strongly, but not deeply, punctate ;

sculpture of the tegmina comparatively strong, the apices not reticulate; clavus separated from the corium

by a deep furrow; underside light testaceous ; legs testaceous.

Oblong-ovate, with fine yellowish pubescence ; head, pronotum, and scutellum dark, with metallic reflections ;

pronotum very closely and subrugosely sculptured ; tegmina black, with the inner basal margins broadly

rufescent ; just behind the scutellum there are four reddish spots in a line (two on each tegmen), the two

inner ones being often almost confluent, and just behind the middle are two similar spots, answering to

the two inner spots behind the scutellum; at the margins are four light testaceous spots (two on each

tegmen, one before and one behind the middle); underside red, except the front part; legs pitchy, with

the knees and the posterior femora and tibie, in part at least, rufescent.

Sphenorhina simulans, Walk. List of Homopt. Ins., Suppl. p. 183 (1858) *.

Tomaspis fasciaticollis, Stal, Stett. ent. Zeit. xxv. p. 63 (1864) *.

Hab. Mexico (Sallé!; Mus. Holm. and coll. Signoret 7), Pinos Altos in Chihuahua

(Buchan-Hepburn), Rincon, Chilpancingo, and Acaguizotla in Guerrero, Teapa in

Tabasco (H. H. Smith), Cuernavaca (Bilimek, in Mus. Vind. Ces.), Jalapa (Hége),

Orizaba (Bilimek, in Mus. Vind. Ces.; H. H. Smith and Ff. D. Godman).

This is a small species, with the ground-colour dark, with two distinct white or

whitish-yellow bands across the tegmina, and one across the pronotum. It is variable,

and presents four distinct forms :—

a. Black or fuscous, with the light bands broad and distinct, and the head, the margins of the pronotum, the

basal angle of the tegmina, and legs and underside more or less testaceous. This is the common form.

6. Pronotal band very narrow; tegmina without light bands. This is the var. “tegminibus impictis” of

St&l; it is not represented in our collection, but there is a specimen in the Vienna Museum labelled as

presented by Stal.

¢. Black, with the light bands much narrower, often reduced to mere lines or elongated spots of a clearer

white colour; abdomen red; legs mostly red or black, with the posterior femora and tibie red. Size

smaller.

dad. Pronotum without white band. Size smaller.

It is possible that one or two of these may belong to distinct species, but they can

hardly be described without more material.

Stal compares 7. fasciaticollis with T. bicincta (Say), and says it is closely akin to it ;

but Say says of his 7. dicincta that it resembles Cercopis rubra and C. sororia, Germ.,

which are quite different insects.

This species is one of the instances in which Stl totally ignores Walker’s description,

although it is quite satisfactory; he has done the same with Monecphora postica,

Walk.=T. pictipennis, Stal, and Sphenorhina assimilis, Walk.= T. varians, Stal. All

three of these species are described by Walker as from Mexico (Sallé), and yet Stal,

though he styles his papers “ Hemiptera Mexicana,” makes no allusion to any of

them.

7. simulans, so far as the formation of the metopidium is concerned, is intermediate

between Monecphora and Sphenorhina, and serves to show how unsatisfactory a generic

character this is.

A specimen of the type form from Teapa is figured.

26. Tomaspis prenitida, sp.n. (Tab. XI. figg. 23, 23 a, 6.)

Oblong, broader in front than behind, the front parts very shiny; pitchy-black, with a whitish wavy band

behind the scutellum and another behind the middle, the suture between these bands being lighter than

the ground-colour; head broad; pronotum very shining, about twice as broad as long, diffusely and

shallowly punctured ; scutellum large, brownish, produced into a sharp point behind; tegmina rather

strongly punctured at the base, very finely so towards the apex, which is not reticulately rugose ;’

A small, short, oblong species, black, with a broad white band a little before the apex, reaching across the

tegmina; head short, but broad, the eyes large and prominent, the metopidium not produced; pronotum

shining, rather strongly and somewhat closely punctured ; tegmina very finely punctured behind, more

evidently so in front, scarcely reticulate at the apex; legs pitchy.

This is a small species, with the tegmina fulvous-hyaline, and with seven very

Oblong, pitchy, scantily pubescent ; pronotum shining, rather strongly but not deeply punctured, with a very

distinct central line ; scutellum very finely transversely rugose; tegmina dull, of a fuscous-pitchy-colour,

with obscure testaceous markings, some of which are often almost invisible or absent; in the type-

specimen there is a lighter spot where the corium joins the pronotum, and two lighter bands across the

tegmina before and behind the middle, more or less broken into spots, the outer ones being the lightest ;

the tegmina are plainly reticulate at the apex ; legs and underside pitchy-testaceous, in part fuscous.

Group 4.

The insects belonging to this group have a very distinct facies, as a rule, although

I. imperans is, perhaps, a somewhat intermediate species. There is no tangible

punctuation very close and fine, the apex plainly rugose-reticulate ; underside dark, the metasternum red ;

legs black.

Long. 10 millim. ; lat. max. 44 millim.

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

Var. sexnotata.

Colore nigro, differt basi pronoti sat late, lateribus anguste, apice tantum scutelli, et tribus maculis tegminum

Black, with the base of the pronotum broadly and the sides narrowly scarlet; the apex only of the scutellum

is of the same colour, and the scarlet marginal band of the tegmina is replaced by three spots on each

side—one at the base, one before the middle, and the third behind the middle.

Oaxaca (Mus. Holm.?; Mus. Brit.); Guatemaua, San Gerénimo (Champion).

Stal enumerates four varieties of this species. In the type form the head and the

front of the pronotum are red, and the hinder part of the latter, except the posterior

margin (which is dark), is light testaceous; the tegmina are dark, with a light

testaceous longitudinal subcostal stripe, which is curved and enlarged in front and

behind and almost encloses a dark oval space divided by the suture; this band,

however, varies and is often quite straight and not thickened behind; the colour of

the head and pronotum is also variable. A single specimen from San Gerénimo in

TOMASPIS. 189

our collection is almost entirely of a fuscous colour, and has the pronotum rather more

distinctly punctured ; it possibly belongs to a distinct species.

I have been enabled to identify Stal’s insect through the kindness of Dr. Aurivillius,

who lent me a typical specimen.

We figure two examples from Omilteme, one of which (fig. 28) is a variety.

(Dyson ', in Mus. Brit.) ; Nicaragua, Chontales (Janson).—Sourn AMERICA ?.

This is a very variable insect, the ground-colour varying from bright scarlet to a

dirty testaceous, and the smallest specimens being about half the size of the largest.

It is not, therefore, to be wondered at that a considerable number of species have been

described which must be sunk as synonyms; a glance over our series and the specimens

in the British Museum will show how they lead one into the other.

There can be little doubt that all the above-mentioned so-called species might be

referred to Sphenorhina lineolata, Amyot and Serville [Hist. Nat. des Ins., Hémipt.

p. 563, t. 10. f. 7 (1843)]; but, as their description is very meagre and the locality is

given as “ Amérique méridionale?” I prefer to adopt the above synonymy.

We figure two specimens—one, of the ordinary form, from Chilpancingo, and a

variety (=S. similis, Walk.) from Teapa.

35. Tomaspis nuptialis. (Tab. XI. figg. 31, 31a.)

Tomaspis nuptialis, Stal, Stett. ent. Zeit. xxv. p. 64 (1864)

Hab. Mexico (coll. Signoret 1, in Mus. Vind. Cas.).

I am inclined to regard this as an extreme variety of the preceding species; but it

has the metopidium a little less produced, and is very strikingly coloured. It is not

represented in our collection.

A specimen of Stl’s in the Vienna Museum collection is figured.

190 HEMIPTERA-HOMOPTERA.

Subfam. PTV ELINA.

In this subfamily the anterior margin of the pronotum is more or less rounded and

produced between the eyes, which are nearly always distinctly transverse. ‘There are,

however, as before stated, one or two transitional forms in which the eyes are round;

but in these the anterior margin of the pronotum is decidedly though not strongly

rounded, and a line drawn through its front part will pass at least through the middle

of the eyes, whereas in the Cercopine the anterior margin of the pronotum is cut off

in a straight line immediately behind ‘the eyes.

The subfamily Ptyeline corresponds to Stal’s Aphrophorida (Hemipt. Afr. iv. p. 66) ;

in his table he makes considerable use of the characters drawn from the venation of the

wings, aud in some cases they appear valuable, but it is a question whether they are

always quite constant.

The Ptyeline are not, apparently, very strongly represented in Central America,

except so far as the insignificant and variable genus Clastoptera is concerned.

The following table will help to distinguish the Central-American genera :—

I. Eyes round or nearly round, the head slightly produced between

them... soe ee ew ew ew ww ww.) ~Neenus, gen. nov.

Oblong-ovate ; head rather large; metopidium very convex and rounded, vertex carinate; eyes nearly round ;

ocelli distinct, more distant from the eyes than from one another; pronotum nearly twice as broad as

long, gently rounded in front and slightly produced between the eyes, the base slightly sinuate; scutellum

nearly equilateral, pointed behind ; tegmina, taken separately, broadly rounded at the apex, the corium

separated from the clavus by a deep suture; wings with the third vein from the outer marginal vein

forked and enclosing a somewhat large triangular apical area; legs robust; posterior tibiee with two

strong sharp spines, the lower one being the longest, and with a strong circle of smaller spines at the

apex.

This genus appears to form a transition between the Cercopine and the Ptyeline.

The species described is in general appearance much like a very small Cercopis.

1. Negenus varius, sp.n. (Tab. XII. figg. 1; 2, var.)

Niger, supra haud nitidus, vertice subtiliter rugoso; metopidio nitido ; pronoto sat fortiter rugoso ; tegminibus

dense et distincte subrugoso-punctatis, maculis duabus ad basin, duabusque pone medium, testaceis vel

flavo-rufescentibus, variantibus, interdum deficientibus ; pectore piceo-testaceo ; pedibus piceis.

Black, rather dull above, shining on the underside; vertex finely rugose, subexcavate ; pronotum rather

strongly, scutellum finely, transversely rugose; tegmina distinctly and very closely rugose-punctate,

each with an oblong straw-coloured patch at the base, occupying half of the clavus, but not extending to

the corium, and a round and rather irregular spot behind the middle quite separate from the margins :

these spots are very variable in size, and are sometimes in part or wholly absent; abdomen black, chest

pitchy-testaceous ; legs pitchy.

The chief varieties appear to be as follows :—

a. Front spots large, straw-coloured ; hind spots moderate, orange.

6. Front spots much reduced, straw-coloured or orange.

c, Hind spots much reduced or absent.

d. Tegmina entirely unicolorous black, without spots.

Long. 6 millim.; lat. max. 23 millim.

Hab. Mexico, Jalisco (Schumann), Chilpancingo 4600 feet, Amula 6000 feet, Soledad

Aphrophora inclyta and A. maura, Walk., from Sarawak (List of Homopt. Ins.,

Suppl. p. 187), appear to be allied to this species.

We figure two specimens—one from Soledad and one from Amula.

192 HEMIPTERA-HOMOPTERA.

CEPHISUS.

Cephisus, Stal, Hemipt. Afr. iv. p.67 (1866) ; Berl. ent. Zeitschr. x. p. 384; Hemipt. Fabr. ii. p. 18.

Aphrophora, Walker, List of Homopt. Ins. iii. p. 697 (ex parte).

So far as regards the structure of the wings this genus is closely allied to Aphro-

phora, from which it differs in the shorter rostrum and the absence of a carina on the

vertex of the head, as well as in the larger size of the species.

Argentina 4+.—! West Arnica !.

This large species, which is widely distributed in Central and South America, appears

to have been always identified with Aphrophora siccifolia, Walk., recorded by him as

from West Africa; possibly there is a mistake as to Walker's locality.

A specimen from Chilpancingo is figured.

LEPYRONIA.

Lepyronia, Amyot et Serville, Hist. Nat. des Ins. Hémipt. p. 567 (1843) ; Stal, Stett. ent. Zeit.

1864, p. 67.

Amyot and Serville distinguish this genus as having the body “ court et ramassé,”

and the “ élytres bombées, en ovale court et en forme de coquille”; a better distinction,

however, is to be found, according to Stal, in the fact that the submarginal vein of the

wings is more or less widely interrupted at the apex, and the wings at rest form a fold

at this point: this is very plain in the larger species, such as L. subfasciata, from

Brazil, of which a tegmen and wing are figured (Tab. XII. figg. 4, 4 a).

1. Lepyronia sordida.

Lepyronia sordida, Stal, Stett. ent. Zeit. 1864, p. 677.

Hab. Mexico (Mus. Holm. & coll. Signoret +).

LEPYRONIA.—APHROPHORA. 193

Superficially, this species, which is not represented in our collection, bears a strong

resemblance to Philenus fusco-varius, Stil. Iam not quite sure whether it would not

be better to separate it from Lepyronia; but, as I have only seen one specimen

(presented by Stal to Signoret and now in the Vienna Museum), I do not feel competent

to do more than pronounce an opinion. The wings appear to answer to Stal’s description

of the genus, but the form is quite different from that of the ordinary species of

Lepyronia.

PHILAENUS.

Philenus, Stal, Stett. ent. Zeit. 1864, p. 66 ; Hemipt. Afr. iv. p. 68 (1866).

This genus differs from Aphrophora in having the vertex of the head and the

pronotum without carine, and in having the third vein from the outer marginal vein

forked at some distance from the apex and forming an apical area, which is distinctly

rounded at the fork.

1. Phileenus fusco-varius. (Tab. XII. figg. 5; 6, var.)

Philenus fusco-varius, Stal, Stett. ent. Zeit. 1864, p. 66°.

Hab. Mexico (Mus. Holm. & coll. Signoret'), Pinos Altos in Chihuahua (Buchan-

Hepburn), Omilteme 8000 feet, Chilpancingo 4600 feet, and Xucumanatlan 7000 feet,

all in Guerrero (H. H. Smith), Orizaba, Cuernavaca, Jalapa (Bilimek, in Mus. Vind.

Ces.); GuateMALA, Chiacam in Vera Paz, Quiché Mountains 7000 to 9000 feet,

Panajachel 5000 feet, Capetillo (Champion).

The specimens in our collection are variable in size and coloration: one, from the

Quiché Mountains, is only 5 millim. in length; and one, from Omilteme, has a large

whitish dorsal patch covering the greater part of the basal half of the tegmina.

We figure a specimen from Pinos Altos, and a variety from the Quiché Mountains. —

APHROPHORA.

Aphrophora, Germar, Mag. Ent. iv. p. 48 (1821); Burmeister, Handb. Ent. ii. p. 121; Amyot et

Serville, Hist. Nat. des Ins. Hémipt. p. 563.

The insects belonging to this genus have the vertex and pronotum plainly carinate,

and the third vein from the outer marginal vein, as a rule, forked, the fork enclosing an

apical area, which is more or less rounded at the apex. This last-mentioned character,

however, is variable: in one species, which appears undoubtedly to be an Aphrophora,

the fork is absent or slightly represented on one side only. The posterior tibie are

robust, with two very strong spines, and with the crown of spiacs at the apex strongly

marked.

1. Aphrophora levior, sp.n. (Tab. XII. fig. 7.)

Brunnea, testaceo-variegata, levior, sat nitida, capite pronotoque testaceis, hoc ad basin brunneco, antice densius

postice diffuse et haud profunde punctato; scutello testaceo ; tegminibus nitidis, ad apicem fere levibus,

clavo sat fortiter punctato ; pedibus testaceis.

Dark brown, with the head, pronotum (except a patch at the base on each side of the central carina), scutellum,

two patches at the margins of each tegmen, and other smaller markings, testaceous ; head rather dull,

distinctly punctured ; pronotum with a rather broad central carina, rather dull and closely punctured in

front, behind shining, comparatively diffusely and not deeply punctured; tegmina shining, with the clavus

and the adjacent portion duller and strongly punctured, and with the apex almost smooth; underside and

legs testaceous or more or less pitchy-testaceous.

Long. 6 millim. ; lat. 3-31 millim.

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

A rather long and very uniform series. This species is rather closely allied to

A. quadrinotata, Say, but is differently sculptured.

2. Aphrophora perdubia, sp. n.

Preecedenti affinis, sed major, minus nitida, densiusque fortiusque punctata, notisque tegminum obscurioribus

distincta.

Allied to the preceding, but on the average larger, evidently duller, with the punctuation more close and

uniform and covering nearly the whole of the tegmina, and with the markings much less distinct ; from

A. grisea it differs in the more pointed head and general coloration.

Long. 7-8 millim.; lat. max. 33-4 millim.

Hab. Mexico ( Bilimek, in Mus. Vind. Ces.) ; GuatEMaLa, Chiacam, Sabo, and Purula

in Vera Paz, Cerro Zunil, Capetillo (Champion).

The two specimens from Sabo, Vera Paz, are a somewhat intermediate form between

this and the preceding species.

There is a small series in the Vienna Museum collection which must apparently be

referred to A. perdubia; the specimens are labelled “ 4-vittata, Signoret,” in litt.

3. Aphrophora grisea, sp.n. (Tab. XII. fig. 8.)

Grisea vel griseo-testacea, fusco-variegata; metopidio testaceo, nigro-notato, basi antennarum nigra, vertice

latiori, distincte regulariter punctato; tegminibus ad medium plus minusve ampliatis, sat fortiter

ad apicem punctatis; vitta obliqué irregulari aliisque notis fusco-brunneis, apicibus fusco-reticulatis ;

abdomine nigro, pectore pedibusque testaceis, fusco-maculatis.

Of a somewhat short-ovate form, widened in the middle of the tegmina, griseous or griseo-testaceous, with a

rather distinct oblique brown band at about the middle of the tegmina and other dark markings, the cells

at the apex being surrounded with dark colour and presenting a reticulate appearance ; occasionally the

head has a greenish reflection ; head rather large, rounded, eyes large and rather prominent ; punctuation

distinct, regular, and fairly uniform over the whole surface, reaching plainly to the apex of the tegmina;

abdomen black, underside of the metopidium, chest, and legs testaceous, variegated. with fuscous; spines

of the posterior tibie black at the apex.

Long. 6-7 millim.; lat. max. 33-4 millim.

Hab. Mexico, Omilteme 8000 feet, Xucumanatlan 7000 feet, and Amula 6000 feet,

all in Guerrero, Teapa in Tabasco (H. H. Smith).

APHROPHORA.—XENAPHROPHORA. 195

In this species the third vein from the outer marginal vein is sometimes simple and

sometimes forked, enclosing a larger or smaller apical area; occasionally such an area

is present on one wing and not on the other.

An example from Omilteme is figured.

Besides the specimens above described there is in our collection a single example

from Balheu, Vera Paz (Champion), which is rather like A. grisea, but appears to be

distinct from that species. I should not, however, care to describe it as new without

further material. The single specimen of A. grisea from Teapa is somewhat different

from the others.

PARAPHROPHORA, gen. nov.

Elongata; capite sat magno, ante oculos producto, obtuse rotundato, ocellis valde approximatis ; metopidio

pedibus teretibus, tibiis posticis longis gracilibus, spinis duabus altera sub apicem parva, altera basin versus

minima armatis.

Closely allied to Aphrophora, but differs in its more elongate form and, especially, in

the slender legs and elongate and slender posterior tibize, which are armed with two

spines, one near the base very small, and one before apex somewhat larger; the crown

of spines at the apex of the posterior tibiz is distinct, but not strongly marked; the

third interior vein from the outer submarginal vein shows no trace of furcation.

1. Paraphrophora simplex, sp.n. (Tab. XII. fig. 9.)

Testacea, unicolor, sat nitida; pronoto longitudine sesquilatiori, sat fortiter punctato, carinato; scutello

Of a uniform testaceous colour, rather shining; head somewhat rugose, pronotum strongly punctured ; tegmina

with one or two very obscure lighter patches at the margins; legs testaceous, with the apex of the

tarsi black.

Long. 8 millim.; lat. max. 3 millim.

Hab. Guatemata, San Gerdnimo, 3000 feet (Champion).

XENAPHROPHORA, gen. nov.

tertid interiore ante apicem furcataé; pedibus teretibus, tibiis posticis longis gracilibus, spinis duabus

parvis armatis.

Very closely allied to the preceding genus, but larger and stouter, with the pronotum

not carinate, the keel being replaced by a broad smooth shining line, on the surface of

which there is sometimes a feeble trace of carination towards the apex; the vertex

shows traces of a carina; wings with the third vein from the outer submarginal vein

furcate at some distance before the apex and enclosing a long narrow apical area; legs

slender, posterior tibize long, with two small teeth.

I at first included this genus under Paraphrophora, but it bears just the same relation

| #209

196 HEMIPTERA-HOMOPTERA.

to the latter genus that Philenus does to Aphrophora; and if the former two are classed

together, the latter should also be united. I believe that, in the face of the occasional

inconstancy of the alar venation (as in Aphrophora grisea), this would be the best

course ; but the genus Philenus has been so generally adopted that I do not care to

discard it in the present state of our knowledge.

1, Xenaphrophora montana, sp. n. (Tab. XII. fig. 10.)

Fusco-brunnea, perobscure variegata, nitida ; vertice densius et rugosius punctato ; pronoto longitudine sesqui-

punctato; tegminibus ad apicem angustatis, dense fortiusque punctatis, venis sat crassis nigro-fusco

testaceoque variegatis.

Fuscous-brown, shining, obscurely variegated with darker and lighter colour; metopidium fuscous in front,

testaceous with dark lines on each side of the centre; vertex closely and somewhat rugosely punctured ;

pronotum about half as broad again as long, not very closely punctured, with a broad smooth fuscous

central line; tegmina fuscous, with some very obscure lighter markings, and with rather strong veins

which are distinctly variegated with dark fuscous and testaceous ; the punctuation is strong and distinct,

and continued to the apex of the tegmina; legs fusco-piceous ; underside testaceous.

Long. 10-11 millim.; lat. 4 millim.

Hab. GuateMaLa, Quiché Mountains, 7000-9000 feet (Champion).

Two females.

MICROSARGANE, gen. nov.

Elongata, angusta, parallela ; capite magno, ante oculos producto, vertice rotundato, oculis magnis transversis,

Elongate, narrow, and parallel, very finely sculptured; head large; vertex considerably produced before the

eyes, rounded at the apex; metopidium convex, nearly smooth; eyes large; ocelli almost as far distant

from one another as from the eyes; rostrum moderately long, reaching the intermediate cox ; pronotum

about twice as broad as long, strongly emarginate in the centre of the base; scutellum rather large,

acutely produced at the apex; tegmina long, parallel; wings with the third vein from the exterior

marginal vein forked at some distance from the apex and forming a large apical area; legs slender;

posterior tibiee with two rather strong spines and a distinct crown of spines at the apex.

This is a very distinct genus, and the species described below is much more diversely

coloured than is usual in the subfamily *. Walker apparently includes it under

Ptyelus, from which it certainly must be separated.

1. Microsargane vittata, sp.n. (Tab. XII. fig. 11.)

Brunnea vel griseo-brunnea, leviter pubescens ; lateribus verticis pronotique late testaceis, colore testaceo ad

medium tegminum continuato, apicibus rufo, testaceo, nigroque variegatis, impressis; metopidio, corpore

subtus, pedibusque testaceis, tarsis ad apicem fuscis.

* In the Oxford Museum there is an insect labelled as having been found at Otaheite by the late Charles

Darwin which must apparently be referred to this genus.

MICROSARGANE.—EPICRANION. 197

Of a brown or greyish-brown colour, finely pubescent; sides of the head and pronotum broadly testaceous,.

this colour being continued to about the middle of the tegmina, and so forming a broad band on each side

of the upper surface; tegmina with a bright red (occasionally brown-red) patch a little before the apex,

with testaceous markings divided by a brown stripe at its side, and behind it black or dark brown

markings, and then a light brown or testaceous band, the extreme tips being margined with dark brown ;

the apex has three or four deep impressions on each side ; underside and legs testaceous, claws pitchy.

Long. 8-9 millim.; lat. 3 millim.

Hab. Nicaraava, Chontales (Janson); Panama, Bugaba (Champion).

This insect is closely allied to Ptyelus mutans, Walk., described as from the west

coast of America; but that species has no light bands at the sides of the pronotum

and is otherwise different.

A specimen from Chontales is figured.

EPICRANION, gen. nov.

Oblongo-ovatum, levissime pubescens, subtiliter sculpturatum ; capite magno, vertice longe ante oculos extenso,

Oblong-ovate, subparallel, with fine pubescence and very close sculpturation; head large, much produced

before the eyes, and with the vertex rounded in a very blunt obtuse angle; eyes comparatively small and

not prominent ; ocelli indistinct, about as far from each other as from the eyes; metopidium long and

flat, so that the head viewed from the side is very narrow ; pronotum rather broader than the tegmina

behind the shoulders, strongly emarginate in a semicircle before the scutellum, which is rather large and

is produced behind into a long acuminate point; tegmina very finely sculptured, slightly rugose at the

apex ; legs short, the intermediate and front pairs slender, the posterior pair robust ; posterior tibize short,

armed with two spines, one towards the base shorter, and the other towards the apex elongate and strong,

the apex with strong spines.

This is a very distinct genus, not far removed from Perinoia, with which, however, it

cannot be confounded. It appears also to be allied to Clawa, Stal.

1. Epicranion championi, sp.n. (Tab. XII. fig. 12.)

Brunneum, unicolor, supra haud nitidum, vertice elongato haud carinato; metopidio nitido, late excavato ;

pronoto subtilissime rugoso haud carinato ad medium antice perobscure impresso; tegminibus sub-

tilissime punctatis; pectore piceo, abdomine pedibusque testaceis.

Of a unicolorous brown colour, dull above, more shining below; metopidium broadly and very shallowly

excavate in the middle, with the projection of the vertex forming hollows on each side of the central

portion ; pronotum about twice as broad as long, very finely rugose; tegmina at the shoulders about as

proad as the pronotum, slightly narrower behind, but subparallel and very little narrowed before the

apex, extremely finely and closely punctured ; base of the rostrum pitchy, very shining; chest pitchy ;

abdomen and legs testaceous.

Long. 7 millim.; lat. max. 3 millim.

Hab. Paxama, Volcan de Chiriqui 2000-3000 feet (Champion).

198 HEMIPTERA-HOMOPTERA.

EICISSUS, gen. nov.

Oblongus ; capite vertice brevissimo, metopidio compresso carinato; oculis magnis transversis, ocellis valde

approximatis; pronoto longitudine fere duplo latiori, rugoso; scutello equilaterali, depresso; teg-

minibus corio subhyalino, venis plus minusve crassis ; alis vena tertia haud furcata, venis transversis valde

obliquis ; pedibus teretibus, tibiis posticis spina ante apicem armatis.

Rather short, oblong, with the vertex extremely short, scarcely projecting at all beyond the eyes, which are

large and transverse; ocelli very closely approximate ; rostrum long; pronotum about twice as broad as

long, rugose; tegmina partly subhyaline, with the veins strongly marked; wings with the third vein

from the outer marginal vein not forked, and the transverse veins very oblique ; legs slender ; posterior

tibie with one spine a little before the apex, and the apex with a crown of short and rather stout

spines.

This appears to be a very distinct genus. It is, perhaps, somewhat allied to Carystus,

Stal, which is peculiar to Australia and Tasmania. The female, at first sight, closely

resembles certain species of Isside.

1. Hicissus decipiens, sp.n. (Tab. XII. figg. 18, 13a, b.)

Fusco-brunneus vel fusco-testaceus, interdum antice colore dilutoriori, rugose sculpturatus; rostro elongato ;

sculptura pronoti tegminumque quoad sexum variante ; pedibus gracilibus, testaceis vel piceis.

Mas angustior, postice acuminatus, pronoto dense subtiliusque rugoso, tegminibusque antice densius fortiusque

punctatis, postice leviter vel vix reticulatis. .

Femina latior et amplior, pronoto fortiter rugoso, tegminibusque corio (parte basali cum clavo fortiter

punctata excepta) crasse reticulato, venis exstantibus.

Of a dark fuscous colour, with the front half sometimes testaceous; metopidium sometimes light, abdomen

black or pitchy, but variable; shape and sculpture varying in the sexes; legs slender, testaceous or

pitchy.

¢o. Narrower, with the tegmina less ample and when closed meeting behind in a point; pronotum and

tegmina more finely sculptured, and the veins of the latter, as a rule, much less strongly marked; the

sculpture, however, is somewhat variable.

©. Broader, with the pronotum very strongly rugose, and the sculpture of the tegmina much coarser, the

greater part of the corium being strongly reticulate with large outstanding veins. | |

Long. 6-7 millim.; lat. max. 24-3 millim.

Hab. Guatema.a, Chiacam, Senahu, and Sinanja in Vera Paz (Champion); Panama,

Bugaba, Volcan de Chiriqui 2500-8000 feet (Champion).

In the small series from the Volcan de Chiriqui the sc ulpture of the males is variable,

but they all apparently belong to one species. I believe I am right as to the sexes, but

as the specimens are mounted on card I have not examined all of them.

A specimen from the Volcan de Chiriqui is figured.

CLASTOPTERA.

Clastoptera, Germar, Zeitschr. fir Ent. i. p. 187 (1839) ; Walker, List of Homopt. Ins. iii. p. 842.

This genus contains a considerable number of very small and inconspicuous species,

which are, apparently, widely distributed in North, Central, and South America. They

are very variable in coloration, and it is almost impossible to distinguish them by

CLASTOPTERA. 199

descriptions*. The various species may at once be known by their small size and

globular or semiglobular appearance. The clavus is very bluntly rounded at the apex,

and in the specimens which I have examined closely the outer marginal vein of the

wings is interrupted by an elongate irregular-oval area at some little distance before

the tip; the third vein from the marginal vein is not furcate.

In the Vienna Museum collection, besides a large number of unnamed specimens,

there are no less than nine species named by Signoret, of which I can find no trace in

any publication; I conclude, therefore, that they are all manuscript names; three of

these species are from California and six from Mexico.

1. Clastoptera funesta. (Tab. XII. figg. 14; 15, var.)

Clastoptera funesta, Stal, Ofv. Kongl. Vet.-Ak. Férh. 1854, p. 2537.

Hab. Mexico, Chilpancingo in Guerrero, Atoyac in Vera Cruz, Teapa in Tabasco

(H. H. Smith), Cuernavaca and San Marcos (Bilimek, in Mus. Vind. Ces.), Orizaba

(Sallé, Bilimek, H. H. Smith, F. D. Godman); GuatemaLa, Tamahu in Vera Paz,

Guatemala city (Champion) ; Honpuras (Mus. Holm.) ; Nicaragua, Chontales (Janson);

Panama, Bugaba, Volcan de Chiriqui (Champion).

The specimens in our collection which I have referred to this species (about 150 in

number), and those in the Vienna Museum (about twenty-five in number), are very

small globose insects, and have the upper surface in most cases of a uniform shining

black colour, or black with the base of the scutellum broadly light yellow. The head,

legs, and underside are all more or less yellow, and the metopidium is usually furnished

with a transverse black line. The apical portion of the tegmina is, as is usual in the

genus, more or less broadly hyaline, and is furnished on each side at the inner angle

with a dark callosity. In some specimens there are lighter markings or obscurely

lighter bands on the tegmina, and others are more or less castaneous, but these appear

to be immature.

I was at first inclined to refer the insects which I have placed under this species to

C. proteus, Fitch, but, after examining the specimens of C. proteus in the British

Museum [ have altered my opinion. I have not seen a named specimen of C. funesta,

Stal, but from the description I have little doubt that his insect belongs to the entirely

black form of the present species. It is possible that three or four of the species

alluded to or described by Stal in the ‘Bidrag till Rio Janeiro-Traktens Hemipter-

Fauna,’ ii. pp. 16, 17 (as C. scutellata, Germ., C. pallidiceps, Stal, and C. tibialis, Stal),

may be synonymous with this variable and evidently abundant species, but I have not

seen any typical specimens of these insects. In the Vienna Museum collection three

* §t&l, ‘ Bidrag till Rio Janeiro-Traktens Hemipter-Fauna,’ ii. p. 16, says: “ Species hujus generis non nisi

coloribus inter se differunt, plurime difficillime distinguuntur et describuntur : ali igitur certe aliarum tantum

varietates.” The punctuation and general size and shape, however, afford fair characters in some cases.

200 HEMIPTERA-HOMOPTERA.

single specimens, named by Signoret, in litt., as C. globulus, C. annulipes, and C. nigrifrons,

appear to belong to C. funesta; they are all labelled as from Mexico.

We figure a specimen of the type form and a variety, both from Teapa in Tabasco.

2. Clastoptera globosa, sp.n. (Tab. XII. fig. 16.)

Rotundata, globosa, nitidiuscula, nigra, capite antice obscure rufo-brunneo, metopidio flavo ; pronoto fere levi;

scutello (apice excepto) flavo, vel toto nigro; tegminibus postice dilatatis, clavo distincte punctato, corio

postico fere levi; corpore subtus nigro, coxis pedibusque flavo-testaceis.

A comparatively large, globose species, black and rather shining, with the head reddish-yellow in front and

the metopidium light yellow ; pronotum with slight traces of transverse rugosities and sometimes with a

trace of a central line ; scutellum almost entirely yellow or quite black ; tegmina dilated behind and very

convex ; corium distinctly punctured ; rostrum moderately long, yellow, with the apex black; underside

black; coxe and legs yellow or testaceous-yellow.

Long. 4—44 millim.; lat. max. 3-33 millim.

Hab. Mexico, Tepetlapa 3000 feet and Chilpancingo 4600 feet, both in Guerrero

(H. H. Smith); Guatemata, San Gerénimo (Champion).

In structure and coloration this insect closely resembles certain varieties of C. funesta,

but it is so very much larger, being about four times the bulk of ordinary specimens of

that species, that it can hardly be included in it.

An example from San Gerdnimo is figured.

There are two specimens in our collection which I have doubtfully referred to

this species—one from XKucumanatlan in Guerrero and one from Teapa in Tabasco

(H. H. Smith); they are somewhat more oblong than the specimens above referred to,

black, with very indistinct lighter markings on the scutellum and tegmina.

3. Clastoptera compta, sp.n. (Tab. XII. fig. 17.)

Oblonga, parva, nitidiuscula, nigra, metopidio testaceo ; pronoto fere glabro, vel leviter impresso-lineato, vitté

lata stramined ; scutello nigro immaculato; tegminibus plus minusve distincte punctatis, parte dimidia

apicali plus minusve hyalina, macula magna ad medium, alidque parva ad marginem, stramineis; callis

sat magnis colore flavo circumdatis ; corpore subtus nigro, pedibus flavis.

A small, oblong, slightly shining species ; black, with the metopidium testaceous, faintly lined with fuscous ;

pronotum almost glabrous or with fine impressed lines, with a broad straw-coloured band across the

middle; tegmina slightly dilated behind, more or less distinctly punctured, with a large straw-coloured

spot at the middle extending across the clavus and on to the corium, and apparently interrupted by the

claval vertex ; there is also a small light spot at the margin; these markings are slightly variable in some

cases, but as a rule they are very constant ; apical half of the tegmina more or less broadly hyaline ; the

apical callosities distinct and surrounded with yellow; underside black ; legs yellow.

Long. 3 millim.; lat. 2 millim.

Hab. Mexico (coll. Signoret, in Mus. Vind. Ces.), Chilpancingo in Guerrero, Teapa

in Tabasco (H. H. Smith), Atoyac in Vera Cruz (Schumann).

The specimens in the Vienna Museum are labelled C. thoracica, Sign., in litt.; as,

however, there is nothing remarkable about the shape of the thorax, I have not adopted

the name.

A fair series has been received from Teapa, one of which is figured.

CLASTOPTERA. 201

4, Clastoptera minima, sp.n. (Tab. XII. fig. 18.)

Oblonga, minima, nigra, metopidio testaceo transversim nigro-lineato ; pronoto leviter transversim rugoso-

lineato, scutello distincte sculpturato; clavo fortiter, corio levius punctato, apice tegminum sat late

hyalino, callis parvis sed distinctis ; corpore subtus pedibusque piceis.

A very small black species, with the metopidium more or less obscurely testaceous and furnished with fine

black transverse lines; the pronotum is finely but distinctly sculptured in transverse lines; the clavus is

strongly punctured, and the corium is less finely but distinctly punctured almost to the apex and more or

less light at the sides; legs pitchy.

Long. 23-3 millim.; lat. 2 millim.

Hab. Muxtco, Orizaba (H. H. Smith & F. D. Godman), Vera Cruz (H. H. Smith).

The very small size, oblong shape, and strong punctuation will easily separate this

species.

We figure a specimen from Vera Cruz.

5. Clastoptera antica, sp.n. (Tab. XII. fig. 19.)

Oblonga, haud nitida, nigra, albido-variegata ; metopidio ad medium longitudinaliter nigro, utrinque concinne

nigro albidoque lineato; pronoto distincte impresso lineato, albido, basi, linea tenui centrali, lineAque

latiori utrinque arcuata nigris; scutello albido-variegato; tegminibus subtiliter sculpturatis ad medium

albido-variegatis, apicibus haud hyalinis, callis indistinctis vel deficientibus; pedibus nigris. Variat

testaceaé variegatione, pedibusque variegatis.

Oblong, dull, black, very constantly variegated with whitish ; metopidium black in the centre, with lines

of white and black on each side; pronotum distinctly impressed with fine lines, whitish, with the base, a

thin central line, and an arcuate line on each side before the apex, black; a band of whitish variegation

passes across the tegmina and scutellum, curving somewhat at the margin, and reaching more or less

down the sides; apex of the tegmina not hyaline, without or with indistinct callosities ; legs black,

occasionally more or less variegated with whitish or testaceous.

Long. 33 millim. ; lat. 2} millim.

Hab. Panama, Volcan de Chiriqui 2500-4000 feet (Champion).

This is one of the most distinct species of the genus which I have as yet come across.

A short series has been received.

6. Clastoptera semivitrea, sp.n. (Tab. XII. fig. 20.)

Subglobosa, nitida, metopidio verticeque testaceis ; hoc lined inter oculos, linedque basali fuscis, illo line&

lata nigra antice notato; pronoto testaceo, disco nigro fere glabro; scutello testaceo, ad basim nigro;

tegminibus testaceis, irregulariter fusco-maculatis, parte dimidia apicali hyalina, callis parvis vel minimis ;

pedibus testaceis.

A subglobose, moderately large, shining species, with the metopidium and vertex testaceous, with dark lines ;

pronotum testaceous, with the disc dark; scutellum testaceous, with a dark triangular spot at the

base; the markings, however, are evidently variable, and some are probably often wanting ; tegmina

with the apical half hyaline, with exceedingly small, though distinct, callosities, and the basal half

testaceous, glabrous, with irregular fuscous markings; underside and legs testaceous.

Long. 44-5 millim. ; lat. 3 millim.

Hab. Mexico, Xucumanatlan in Guerrero, Teapa in Tabasco (H. H. Smith).

The description is taken from the specimens from Teapa. ‘The single example

from Xucumanatlan has the markings different, the callosities larger, and the apical

half of the tegmina less transparent ; it may belong to another species.

A specimen from Teapa is figured.

7. Clastoptera flavivitta, sp.n. (Tab. XII. fig. 21.)

Oblonga, parallela, nitida, capite antice metopidioque rufo-flavis, hoe vitta transversali nigra ; pronoto fere

levi; scutello, apice excepto, flavo; tegminibus piceis vel piceo-brunneis, distincte punctatis, basi

anguste flava, coloreque ad marginem ante medium et ad apicem dilutiori; abdomine nigro ; pedibus

flavis, ad partem piceis.

A small, oblong, parallel, shining species, with the fore part of the head reddish-yellow ; pronotum nearly smooth,

with very slight traces of rugose lines ; scutellum, except the apex, light yellow; tegmina pitchy-brown

or black-brown, with a light patch at the margin behind the shoulders, and with the base light yellow in

a line with the breadth of the yellow colour of the scutellum, the whole forming a transverse yellow band

across the body immediately behind the pronotum; underside black; legs, cox, and part of the _

chest yellow, posterior legs more or less pitchy.

Long. 3-33 millim.; lat. 2 millim.

Hab. Guatemata, San Gerdénimo and Purula in Vera Paz (Champion).

We figure a specimen from Purula.

8. Clastoptera dimidiata, sp.n. (Tab. XII. fig. 22.)

Oblonga, nigra, nitidiuscula, capite, pronoto, scutello, apice excepto, maculaque utrinque magna ad basim

clavi lete flavis; pronoto fere levi, lineis transversis indistinctis; clavo leviter, corio vix punctato, fere

glabro, macula hyalina ad marginem sub medium; corpore subtus nigro, coxis piceis; pedibus nigris,

tarsis posticis partim testaceis.

An oblong and rather shining species, with the head, pronotum (except a very small patch at the extreme

angle behind the eyes), scutellum (except the extreme apex), and a large patch near the base of

the clavus, bright yellow; the actual base of the clavus and the rest of the tegmina, except a hyaline

patch at the margins and one or two marks over the apex, are black; clavus lightly punctured; corium

almost glabrous; the usually black callosity at the apex of each tegmen is present, but is merged into

part of the coriaceous portion ; legs black, the anterior and intermediate tibizs with two yellow spots and

the posterior tarsi partly testaceous.

Long. 43 millim.; lat. max. vix 3 millim.

Hab. Panama, Volcan de Chiriqui 2500-4000 feet (Champion).

9. Clastoptera obtusa. (Tab. XII. figg. 23; 24, var.)

Cercopis obtusa, Say, Journ. Acad. Phil. iv. p. 339 (1824) '; Complete Writings, ii. p. 256°.

8000 feet (H. H. Smith); Guavemata, San Gerdénimo and Tactic in Vera Paz,

Panajachel (Champion); Panama, Volcan de Chiriqui (Champion).

This is a rather large oblong species, and varies considerably in colour, some

specimens being light and others dark brown mottled with testaceous, while others

again have the ground-colour quite black. It is allied to C. lenata, but is twice

the size.

CLASTOPTERA. 203

I have with some reserve assigned the numerous specimens from the above-mentioned

Central-American localities to this apparently rather common North-American species,

as I cannot satisfactorily distinguish them from typical examples of C. obtusa, Say,

in the Oxford Museum, presented by Mr. Asa Fitch; very few, however, of the

North-American species reach so far south as Mexico.

Among the specimens in our collection there is one from the Volcan de Chiriqui

which is of a light testaceous-yellow colour, with the apex of the tegmina, a spot

before the middle of the clavus, and the pronotal and frontal stripes fuscous ; this insect

very much resembles C. lineatocollis, Stal (from California), except that the lines on

the pronotum are not nearly so marked and the punctuation is less strong. It is

possible that C. lineatocollis is only an extreme variety of this species. In the Vienna

Museum collection there is a very pretty variety from California (labelled lineata, Sign.,

in litt.) with the head and most of the pronotum nearly white and the tegmina dark

brown, with the irregular whitish bands strongly marked. The larger specimens in

the Vienna Museum are labelled C. orbiculata, Signoret, in litt.

We figure a specimen from Omilteme, and a variety from Tactic, Vera Paz.

10. Clastoptera lenata, sp.n. (Tab. XII. fig. 25.)

Oblonga, parva, haud nitida, brunnea vel fusco-brunnea, obscurior vel dilutior, variabilis, capite pronotoque

albidis lineatim vel maculatim variegatis ; scutello albido-marginato; tegminibus, corpore subtus, pedibus-

que brunneo-, fulvo-, castaneo-, albidoque-variegatis ; pronoto transversim impresse lineato ; tegminibus

subtilissime punctatis, apice plus minusve hyalino vel toto colorato, callis nigris distinctis vel in colorem

apicis mergentibus.

A small, oblong, dull species, of a brown or fuscous-brown colour, variegated with whitish or testaceous-

white, varying very considerably in depth of shade and in markings; the markings, however, of the

head and metopidium are usually in distinct transverse fine light and dark lines, while the pronotum is

more or less light, with two spots in the middle and two dashes in a line with these at the sides, or

it is marked more or less in bands of light and dark; occasionally the whole disc of the pronotum is

dark, or the markings are entirely absent and the whole is light; the scutellum, tegmina, underside,

and legs are variegated with the same colour, and are very variable in this respect, but the normal

marking appears to be an irregular band of whitish colour across the middle of the tegmina, which is

more or less inclined to break up and spread; the subapical callosities are distinct in the specimens

which have the tegmina hyaline at the apex, but in some cases, where the apex is only partially or

scarcely hyaline, they are indistinct and merge in the ground-colour ; the sculpture of the tegmina is very

close, rendering them in typical specimens quite dull, except at the extreme apex.

Long. 3-4 millim. ; lat. 2-23 millim.

Hab. Mexico, Ciudad in Durango 8000 feet (Forrer), Puebla, San Marcos, and

Orizaba (Bilimek, in Mus. Vind. Ces.), Teapa in Tabasco (H. H. Smith); GuaTeMa.a,

Balheu and San Gerénimo in Vera Paz, Cerro Zunil, El Reposo (Champion); Panama,

Bugaba, David, and Volcan de Chiriqui (Champion).

There is a large series of this species unnamed in the Vienna Museum collection.

I have not seen the types of the various Clastoptera from Rio Janeiro described by

Stal (Bidrag till Rio Janeiro-Traktens Hemipter-Fauna, ii. pp. 17, 18), and it is not

*26 2 .

204 HEMIPTERA-HOMOPTERA.

unlikely that the present insect may be referable to one or more of his species 5-10.

It is, however, impossible to identify these from the descriptions, and several of his

so-called species are evidently nothing more than varietal forms, from what Stal says

himself; he makes no allusion either to shape or punctuation. C. triangulum, Walk.,

from Bahia, very closely resembles C. lenata, but the type in the British Museum is

broken in two, and half is lost.

A specimen from El Reposo is figured.

11. Clastoptera stali, sp. n. (Tab. XII. fig. 26.)

Oblonga, sat lata, nigra, nitidiuscula, metopidio flavo-vittato ; pronoto nigro flavo-marginato, subtiliter lineatim

impresso ; scutello late flavo-maculato ; tegminibus utrinque et apice scutelli flavo notatis, clavo distincte

punctato, apice fusco vix hyalino, callis permagnis nigris ; pedibus piceis, posticis obscure variegatis.

Variat colore dilutiore maculisque diversis. .

Oblong, rather broad, deep black, slightly shining; vertex with one, metopidium with two broad yellow bars;

pronotum smooth, with traces of fine impressed lines, margined regularly all round with yellow;

scutellum with a broad yellow patch before the base, and a small one before the apex; tegmina with the

clavus distinctly punctured, especially towards the base, with yellow markings, which with the hinder

mark on the scutellum form an irregular arc at about the middle, the apex fuscous, scarcely hyaline,

the callosities very large and distinct, black ; underside black, in part testaceous ; legs pitchy-testaceous,

with the tarsi darker and the hinder pair obscurely variegated with fuscous and testaceous. The species

appears to vary considerably in colour and markings.

Long. 33 millim. ; lat. 23 millim.

Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith); Guatemata, Las Mercedes

3000 feet (Champion); Panama, Bugaba and Volcan de Chiriqui 2500 to 4000 feet

(Champion).

The type-form from Las Mercedes, which is figured, seems very distinct; the others

might be described as separate species on the colour-markings. C. stali appears to be

allied to certain forms of C. funesta.

12. Clastoptera chiriquensis, sp. n. (Tab. XII. fig. 27.)

Parva, oblonga, vix nitida, testaceo-brunnea, testaceo-variegata ; capite pronotoque brunneis vel fuscis testaceo-

vittatis, hoc distincte transversim lineatim impresso; scutello fere toto testaceo; tegminibus, preesertim

clavo, plus minusve distincte punctatis, testaceo-brunneis testaceo-variegatis, maculé parva ad marginem

apicem versus calloque distincte fuscis ; pedibus testaceis.

A small, oblong, slightly shining species, variegated with light brown and testaceous ; head and pronotum dark,

with testaceous bands, the pronotum distinctly impressed with transverse lines; scutellum entirely

or almost entirely testaceous; clavus distinctly punctured; tegmina variegated with light brown

and testaceous, sometimes obscurely darker in parts, with a fuscous spot at the margin towards the apex,

and with well-marked callosities (the testaceous markings are arranged irregularly across the middle and

spread up the sides); legs testaceous, tarsi darker, posterior pair in parts obscurely pitchy.

Long. 3-3} millim. ; lat. 2 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

A small and fairly constant series. At first sight this species looks like C. lenata,

but it is more shining and the general coloration is different.

CLASTOPTERA. 205

13. Clastoptera flavifrons. (Tab. XII. fig. 28.)

Clastoptera flavifrons, Germ. Zeitschr. fiir Ent. i. p. 189°. |

Hab. Mexico (coll. Signoret, in Mus. Vind. Ces.).—Brazil 1.

This is a small, oblong, brownish species, with the head, pronotum, and scutellum of

a yellowish colour; structurally it closely resembles one or two allied forms, and may

be only a variety of one of them. The species from Mexico in the Vienna Museum

is figured.

14. Clastoptera rufescens, sp. n.

Parva, nitida, capite, pronoto, scutelloque rufescentibus, metopidio ad medium testaceo utrinque transversim

rufo-fusco testaceoque lineato ; pronoto sat fortiter transversis lineis impresso, antice testaceo-marginato ;

tegminibus nitidis, hyalinis, sat fortiter punctatis, venis rufescentibus, callis nigris, distinctis ; corpore

subtus nigro; pedibus rufo-testaceis.

A small shining species, with the head, pronotum, and scutellum rufescent; pronotum rather strongly

impressed with rugose lines, the anterior margin testaceous; tegmina shining and transparent, rather

strongly punctured, with the veins rufescent and without markings, the subapical callosities very distinct,

black ; abdomen black; legs rufo-testaceous.

Long. 3 millim. ; lat. 2 millim.

Hab. Mexico, Chilpancingo in Guerrero 4600 feet (. H. Smith).

This species appears to be allied to the North-American C. canthocephala, Germ.,

which is, however, a darker and less shining and transparent insect.

We have also received a specimen from Teapa in Tabasco, which I at first referred

to this species, but it is rather larger, with a fuscous patch at the margin of the

tegmina and very small testaceous apical callosities.

15. Clastoptera unicolor, sp.n. (Tab. XII. fig. 29.)

Oblonga, parva, postice nonnihil dilatata, sordide testacea, nonnihil nitida, pronoto vix transversim lineis

impresso; tegminibus plus minusve distincte, interdum sat fortiter, punctatis, callis modicis, nigris,

_distinctis ; pedibus testaceis.

A small, oblong species, more or less dilated behind, of a uniform dirty testaceous colour (occasionally reddish),

with the pronotum faintly impressed with transverse lines, and the tegmina (especially the clavus) more

or less distinctly punctured ; legs testaceous; underside somewhat pitchy.

Long. 3 millim.; lat. 2 millim.

Hab. Mexico (Bilimek, in Mus. Vind. Ces.), Vera Cruz (H. H. Smith); Guaremana,

San Gerénimo (Champion). |

This insect appears to be inseparable from C. arkansasensis, Fitch, in litt., and is

also allied to C. rufescens and C. xanthocephala, Germar, as well as to C, testacea,

Fitch ; the last-mentioned species is longer, and differs in several particulars.

A specimen from Vera Cruz is figured.

206 HEMIPTERA-HOMOPTERA.

16. Clastoptera irrorata, sp.n. (Tab, XII. fig. 30.)

Precedenti affinis, sed haud nitida, paullo latior, punctisque parvis fuscis vel nigris dense supra irrorata.

Very like the preceding, but rather broader, with the upper surface quite dull, and closely sprinkled with

more or less distinctly fuscous punctures, which are stronger on the pronotum and scutellum than on the

tegmina, and are absent on the apical portion of the corium, which is broadly hyaline.

Long. 3} millim. ; lat. 23 millim.

Hab. Mexico, Orizaba (Bilimek, in Mus. Vind. Ces.).

ADDENDA.

Two species have been omitted from our list of the Cercopide, from the genus

Tomaspis, and are here added.

TOMASPIS (antea, p. 175).

4(a). Tomaspis costaricensis.

Sphenorhina costaricensis, Distant, Ent. Monthly Mag. xvi. p. 61 (1879)’.

Hab. Costa Rica, Caché (fogers 1).

The insect described and figured by me (anted, p. 177, Tab. XI. fig. 5) under the

name 7. 14-notata, from Chontales, Nicaragua, is perhaps nothing more than a variety

of 7. costaricensis, which has the spots on the tegmina red and the margins of the

pronotum concolorous with the disc.

36. Tomaspis conspicua. (lab. XIV. fig. 23.)

Sphenorhina conspicua, Distant, Ent. Monthly Mag. xvi. p. 62°.

Hab. Costa Rica, Caché (Rogers ').

This species is quite distinct from any of the others enumerated by me.

DIESTOSTEMMA. | 207

Fam, TETTIGONIIDA.

The members of this family are characterized by having the ocelli, which are usually

very conspicuous, on the disc of the vertex of the head, so that they look directly

upwards and are at right angles to the perpendicular axis of the eyes; the latter are

usually promiment; the general form is elongate, sometimes considerably narrowed

behind, but usually parallel; and the hind tibie are multispinose.

The Tettigoniidze include a very large number of species, the genus Tettigonia, as

limited in this work, being cosmopolitan ; the characters, however, of the genera which

have hitherto been formed are most unreliable, owing to the occurrence of such a large

number of intermediate forms. Amyot and Serville tried to divide the family, but

apparently they had hardly any material to work upon, and Walker, while adopting

their genera, seems to have had very little idea of their limits or characteristics: this

is, perhaps, not to be wondered at, as nothing can be more meagre than Amyot

and Serville’s descriptions. Signoret, at the beginning of his Monograph [ Ann. Soc.

Ent. Fr. sér. 3, i., ii., iii, (1853-1855) |, which still remains the most important work

on the group, simply ignores all the genera and places the whole of the species under

Tettigonia ; he gives his reasons in full (doc. cit. i. pp. 16-18), and everyone who

works at the group must agree with what he says as to the impossibility of making

any satisfactory division owing to the fact that the characters always overlap in some of

the species. Stal (Kongl. Svensk. Vet.-Ak. Handl. Band viii. No. 1) is the only writer

who has made a serious attempt to tabulate the family, and I have thought it best, to a

certain extent, to follow him, more for convenience’ sake than because he has in any way

settled the question, for the very large genus Tettigonia, containing by far the greater

part of the species belonging to the family, will remain practically untouched. Although

Signoret does not adopt genera, yet he throws the inclusive genus Tettigonia into groups

and series which are very uneven and more confusing than Stal’s genera.

I have not followed St&l in giving a dichotomous table of the group, as it appears

to me impossible to draw up one that is of any practical use: the characters are

transitional and it is only by taking a number of them together that any division at all

can be made.

DIESTOSTEMMA.

Diestostemma, Amyot et Serville, Hist. Nat. des Ins. Hémipt. p. 572 (1843).

The members of this genus appear to be widely distributed in Central and South

America; they are conspicuous insects, resembling white moths. The head is very

considerably produced in a blunt triangle, and the ocelli are much nearer to the eyes

than is usual in the Tettigoniide ; it is furnished in front, in one species at least, with

a long snout-like appendage, which fits on to a small peduncle—the use of this is not

apparent as it is very easily shed, one specimen only in our collection possessing it.

208 HEMIPTERA-HOMOPTERA.

Signoret notices this structure (Ann. Soc. Ent. Fr. 1855, p. 526), but apparently he had

not seen an example furnished with it: it is probable that every member of the genus

possesses the appendage at some period or other of its existence, as a circular cicatrix

or small peduncle, as observed by Signoret, is always present at the apex of the head ;

in some specimens, however, the character is much more conspicuous than in others.

1. Diestostemma albipenne.

Cicada albipennis, Fabr. Syst. Rhyng. p. 62 (1808) *.

Diestostemma albipenne, Amyot et Serv. Hist. Nat. des Ins. Hémipt. p. 572°.

Diestostemma albipennis, Walk. List of Homopt. Ins. iil. p. 798 *.

Tettigonia albipennis, Sign. Ann. Soc. Ent. Fr. 1855, p. 526°.

Hab. Guatemaua, Cerro Zunil 4000-5000 feet, Las Mercedes 3000 feet (Champion) ;

PanaMa, Bugaba, David, Volcan de Chiriqui 2000-3000 feet, Tolé (Champion), Chiriqui

(Mus. Holm.).—Sovuta America 1, Para 3, Brazil 23 4.

I have retained Amyot and Serville’s name “albipenne” as they give the derivation

of their generic name and show that it is of the neuter gender ; Walker was in error in

altering the name to “ albipennis.”

2. Diestostemma nigropunctatum.

Tettigonia nigropunctata, Sign. Ann. Soc. Ent. Fr. 1855, p. 527°.

Hab. Mexico! (Mus. Vind. Ces.).

This species differs from the preceding in being more elongate and slender, with the

head longer and smoother, and the forehead more flattened; the pronotum is less

convex and the humeral angles are somewhat differently shaped. Signoret appears to

be doubtful as to its right to be regarded as a separate species, but it certainly seems

distinct.

8. Diestostemma rugicolle. (Tab. XIII. figg. 1, 1a.)

Tettigonia nigricollis, Sign. Ann. Soc. Ent. Fr. 1855, p. 525, t. 21. fig. 18 *.

Hab. Mexico (Sallé1), Atoyac in Vera Cruz (Schumann, H. H. Smith), Misantla

(F. D. Godman), Teapa in Tabasco (H. H. Smith); Brivish Honpuras, Belize

(Blancaneaux).

This species may easily be distinguished from D. albipenne by the much more

pronounced side-angles of the pronotum, and the large yellowish rugosities on its disc ;

the appendage of the head is cultriform and flattened at the sides, and it is about as

long as the head and pronotum together. .

We figure a specimen from Atoyac and the side of the head of an example from

Misantla.

AMBLYDISCA. 209

AMBLYDISCA.

Amblydisca, Stal, Kongl. Sv. Vet.-Ak. Handl. Band viii. 1 (Hemipt. Fabr. ii.), p. 61, nota (1869).

In this genus the pronotum is narrowed in front, the head has the vertex strongly

impressed, and the metopidium is flat or slightly depressed ; the chief character, how-

ever, lies in the clypeus, which is strongly raised and, when viewed from the side, forms

almost a right angle; the depressed metopidium and the part of the clypeus above the

angle lie in nearly the same plane. The characters of the front part of the head are

much the same as those on which Amyot and Serville founded the genus Sphenorrhina ;

but the head varies so much in shape in different species belonging to the last-named

genus, and so many intermediate forms occur, that it is impossible to draw a hard-and-

fast line between Sphenorrhina and its allied genera, whereas the characters of

Amblydisca appear to be distinct and constant. I have no hesitation, therefore, in

adopting Stal’s genus, which he used for the reception of Tettigonia (Aulacizes) rubri-

ventris, Sign., and three species described by himself under Aulacizes.

1. Amblydisca salvini, sp.n. (Tab. XIII. figg. 2, 2 a.)

Fusco-castanea, antice flavo-maculata, tegminibus olivaceo-virescentibus marmoratis, maculis quatuor flavis ;

vertice brevi, apice late rotundato, impressione profunda flava ; metopidio depresso, ad medium unimaculata;

pronoto transversim rugoso, quinquemaculato, lateribus antice sensim angustatis; scutello macula

rotundataé; tegminibus ad apicem subhyalinis, remotius punctatis; pedibus et pectore rufo-castaneis ;

abdomine fusco ; alis fusco-purpureis.

A large species ; front parts of a deep purplish-castaneous colour, with a round depression on the vertex, and

with two spots on each side of the head and a central spot on the metopidium orange-yellow; vertex

very short, slightly and broadly rounded; almost subtruncate ; eyes prominent; pronotum considerably

broader than long, rugose, with an almost smooth transverse impression in front, and with a yellow spotin

front and four others almost in a line about the middle; scutellum smooth in front, finely rugose behind,

with a round yellow spot on its anterior portion ; tegmina olive-green, variegated with yellowish-green and

mottled with castaneous, presenting a marbled appearance ; at the base near the shoulders are two yellow

spots, one on each tegmen, and there are also two or three others at the sides of the sternum near these ;

the apex of the tegmina is subhyaline and is furnished with a yellow spot, which is more or less irregular

and often broken into two or three ; the underside and legs are reddish castaneous, the abdomen being

fuscous.

Long. 18 millim. ; lat. ad hum. 5 millim.

Hab. Panama, Caldera, Bugaba, Volcan de Chiriqui 2500-4000 feet (Champion),

Chiriqui (Mus. Holm.).

This is the finest species of Tettigoniide in our collection, and I have also found a

single example of it among some unnamed material belonging to the Stockholm

Museum. A specimen from Bugaba is figured.

2. Amblydisca rubriventris. (Tab. XIII. figg. 3, 3a.)

A specimen from Sabo, Vera Paz, is figured.

3. Amblydisca nitidipennis.

Aulacizes nitidipennis, Stal, Stett. ent. Zeit. xxv. p. 79 (1864) °.

Hab. Mexico (Mus. Holm.").

4, Amblydisca bugabensis, sp. n. (Tab. XIII. figg. 4, 4a.)

Fusca vel fusco-rufa; vertice brevi, subtriangulari, fortiter impresso; metopidio depresso, macula magna ad

medium et parte ante clypeum rufo-flavé; pronoto postice transversim rugoso, macula utrinque ad

medium ; scutello postice rufo-flavo; tegminibus sat levibus, subnitidis, vittis quibusdam irregularibus

rufo-flavescentibus plus minusve distincte instructis; pectore antico ad latera albo-piloso; abdomine

pedibusque fusco-rufis.

A fuscous or dark reddish-fuscous species, with a central spot on the metopidium, the parts above the clypeus,

two distinct and constant spots on the pronotum, part of the scutellum, and more or less irregular thin

bands on the tegmina reddish-yellow; vertex short, rounded in front, subtriangular; metopidium

depressed ; pronotum with the sides almost parallel ; tegmina smooth and rather shiny, with fine scattered

punctures, in some lights with a strong bluish or purplish reflection, which is apparently a common

characteristic of several allied species ; abdomen and legs lighter or darker fuscous-red.

Long. 14 millim.; lat. ad hum. 44 millim.

Hab. Panama, Bugaba (Champion).

This species is closely allied to A. nitidipennis, and may possibly be a variety of it;

but the two constant round spots on the pronotum and the absence of scattered minute

spots on the tegmina will serve to distinguish it.

5. Amblydisca: lugubris, sp. n. |

Precedenti affinis, sed vertice paullo longiori; capite, pronoto et scutello immaculatis, castaneis ; tegminibus

brevioribus, fuscis, castaneo obscure variegatis; pedibus et corpore subtus fusco-rufis.

Allied to the preceding species (4. bugabensis), but with the vertex a little longer and the tegmina shorter, and

without any definite spots or markings; the front parts are castaneous, and the tegmina are dark, with

a strong bluish reflection, and are obscurely mottled, especially in front and behind, with castaneous.

Long. 113 millim.; lat. ad hum. 44 millim.

Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion).

6. Amblydisca postfumata, sp.n. (Tab. XIII. figg. 5, 5a.)

Fusca vel fusco-castanea ; vertice brevi, subtriangulari ; metopidio depresso, macula ad medium et parte supra

clypeum flavis; pronoto immaculato, leviter rugoso, antice vix angustato ; scutello nigro, postice flavescenti ;

tegminibus fere levibus, fusco-flavescentibus, subhyalinis, apice late fumato, nigrescenti; pedibus et corpore

subtus fusco-rufis.

Fuscous, with the part just above the clypeus, a central spot on the metopidium, and more or less of the

scutellum towards the apex yellow, and the tegmina of a fuscous-yellowish colour, semi-transparent,

darker towards the base, and with the apex broadly fuscous as if smoked; the pronotum has the sides

AMBLYDISCA, 211

very slightly converging in front, and is finely rugose, and the tegmina are almost smooth, being very

remotely and finely punctured ; legs reddish. |

Long. 14-15 millim.; lat. ad hum. 44 millim.

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

A fair series. This is a very distinct species, but some of the specimens appear to

lose their colour and become almost entirely fuscous and opaque, and in this state

might easily pass unrecognized.

7. Amblydisca fluctuosa, sp. n. (Tab. XIII. figg. 6, 6a.)

Angustior, fusca, cerulescens, maculis rufis variantibus sparsa; vertice brevi, subtriangulari, retundato; capite

cum pectore fusco-testaceo, ad partem rufo; pronoto subparallelo, subrugoso, maculis duabus rufis

instructo ; scutello postice rufo; tegminibus fere levibus, rufo-maculatis ; pedibus testaceis; abdomine

leete rufescenti; variat maculis testaceis.

Narrower than the preceding species (A. postfumata), fuscous, with a very strong blue reflection in certain

lights ; vertex, metopidium, and chest testaceous, the clypeus being orange, and the part just above it and

a central spot on the metopidium red or orange; pronotum rugose behind, subparallel; clypeus with a

large red spot at the apex; tegmina scarcely punctured, narrowed towards the apex, with red spots of

varying sizes arranged more or less in rows, some being very minute, while of the larger ones three

or four more or less distinct transverse rows can be traced across the closed tegmina ; legs testaceous ;

~ abdomen of a bright red colour.

Long. 11-12 millim.; lat. ad hum. 3-4 millim.

Hab. Panama, Caldera, Tolé (Champion).

This is a very distinct and pretty species; certain forms of Aulacizes resemble it, but

the short head and the shape of the clypeus will easily distinguish it from these. The

single specimen from Tolé is shorter and smaller, and has testaceous instead of red

markings; this, however, is a common character in certain species of the group. A

specimen from Caldera is figured.

8. Amblydisca tapes, sp. n. (Tab. XIII. figg. 7, 7 a.)

Elongata, sat angusta, brunnea vel fusca, testaceo flavoque variegata; vertice subtriangulari; metopidio

longitudinaliter impresso, impressione testacea marginibus fuscis; antennis prelongis; pronoto transversim

rugoso, fusco, maculis novem testaceis vel flavis, lateribus antice sensim angustatis; scutello variegato ;

tegminibus maculis flavo-rufescentibus dense sparsis, duabus vel tribus ad basim, ad medium et ante

apicem precipue conspicuis; abdomine fusco-testaceo vel fusco; pedibus testaceis, tarsis tibiisque ad

partem fuscatis.

Of a fuscous or dark testaceous-brown colour, variegated with testaceous and reddish-yellow ; vertex subtri-

angular, moderately produced ; metopidium with the depressed part narrower than in the preceding

species (A. fluctuosa), testaceous, bounded with fuscous, and beyond this again testaceous; pronotum

distinctly but gently narrowed in front, with nine testaceous or yellow spots; scutellum large; tegmina

scarcely punctured, usually rather shiny, with a large number of reddish-yellow spots, some considerably

larger than others—the most conspicuous are two more or less ocellate spots towards the apex, behind

which come several irregular longitudinal confluent spots, forming in all a broad border to the apex of

the tegmina ; legs testaceous, with the tarsi and apex of the tibie fuscous.

Long. 138-14 millim.; lat. max. 34 millim.

Hab. Mexico (Sallé; Mus. Brit.) ; Guatemata, Sabo in Vera Paz (Champion). |

We figure a specimen from Sabo.

212 HEMIPTERA-HOMOPTERA.

9. Amblydisca aulwata, sp.n. (Tab. XIII. figg. 8, 8a.)

Precedenti affinis, sed depressione metopidii toté fusca, pronoto maculis decem vel duodecim, lateribus magis

parallelis ante apicem substrangulatis, et maculis tegminum aliter dispositis facile distinguenda.

In form resembling the preceding species (A. tapes), but slightly larger, with the sides of the pronotum more

parallel, and the usual anterior depression continued deeply to the sides in front, giving a slightly

strangulate appearance; pronotum with more testaceous spots; scutellum broadly testaceous behind ;

tegmina castaneous, with a large number of irregular light testaceous markings, of which the most

conspicuous are perhaps an irregular row of spots on the edge; underside and legs light testaceous, the

tarsi more or less infuscate.

Long. 14-15 millim.; lat. ad hum. 4 millim.

Hab. Nicaracua, Chontales (Janson); Panama, Bugaba (Champion), Chiriqui (Mus.

Holm.).

This and the preceding species appear to represent a common type of coloration

among the insects belonging to the present division of the Tettigoniide; A. auleata

is difficult to describe, but it may be easily recognized from the figures. ‘lhere are

several allied forms from Brazil in the British Museum. .

A specimen from Chontales is figured.

10. Amblydisca multiguttata.

Aulacizes multiguttata, Stal, Stett. ent. Zeit. xxv. p. 80 (1864) *.

Hab. Mexico! (Mus. Holm.; Mus. Vind. Ces.).

In the Vienna Museum there is an Améblydisca labelled ‘‘ multimaculata, det. Stal,”

which must apparently be referred to this species. It is not represented in our

collection, and I have not seen Stal’s type.

11. Amblydisca coriacea.

Aulacizes coriacea, Stal, Stett. ent. Zeit. xxv. p. 80 (1864) *.

Hab. Mexico! (Mus. Holm.; Mus. Vind. Ces.); Guatemata, San Juan in Vera Paz

(Champion).

The single specimen in our collection is unicolorous, without spots, whereas the

typical example has the tegmina irrorated with small white spots and furnished with a

few larger ones. A. coriacea may easily be known by the head being considerably

produced in an equilateral triangle, and by the raised reticulation of the elytra.

12. Amblydisca gigas, sp.n. (Tab. XIII. figg. 9, 9a.)

Major, fusco-castanea, antice rufo-castanea, sat nitida ; vertice valde producto triangulari, levi; metopidio plano;

pronoto sat longo, fortiter rugoso-punctato, lateribus antice leviter sensim angustatis ; scutello ad medium

depresso ; tegminibus ad basim punctatis, deinde subrugosis, ad apicem lavibus; abdomine fusco; pedibus

testaceis vel rufo-testaceis, tarsis genibusque nigris.

A very large and conspicuous, castaneous species, with the vertex much produced in a large, almost, isosceles

triangle, and smooth and shining ; pronotum with the sides slightly but plainly narrowed in front, strongly

and rugosely punctured; scutellum large, impressed and apparently divided in the middle; tegmina

AMBLYDISCA.—-CATORTHORRHINUS. 213

strongly punctured at the base, and smooth and shining at the apex, with the part between dotted

with small rugosities, which, for the most part, proceed as short irregular lines from the strongly raised

veins ; abdomen pitchy; legs variegated with reddish and yellowish-testaceous, the tarsi, knees, and

femora pitchy.

Long. ad apicem abdominis 24, ad apicem tegminum 19 millim.; lat. ad hum. 5 millim.

Hab. Costa Rica (Sallé).

I feel considerable hesitation in retaining this and the preceding species under

Amblydisca, but it is best, in the present state of our knowledge, not to multiply the

genera of the group without very good reason; if we are to go by the shape of the

clypeus they fall under Amblydisca, if by the formation of the vertex they may well be

separated from it. A transition, however, is afforded by A. multiguttata.

ACROBELUS.

Acrobelus, Stal, Kong]. Svensk. Vet.-Ak. Handl. Band viii. 1 (Hemipt. Fabr. ii.), p. 60, nota (1869).

This genus was formed by Stal to receive Tettigonia reflera, Sign., which appears to

be synonymous with Rhaphirhinus attenuatus, Walk.; it may be distinguished from

Raphirhinus, Lap. (Rhaphidorhinus, Stal), by the head being gradually prolonged into a

stout recurved process, which is excavate above and below, whereas in the last-named

genus (which is represented by &. phosphoreus and Tettigonia rugosa) the process is

slender and not excavate above, and proceeds abruptly from the head, the apex of

which is much broader than the process. |

CATORTHORRHINUS, gen. nov.

Axylacizi similis, sed vertice declivi in processum brevem erectum producto, hoc supra subtusque profunde

excavato; metopidio a latere viso ut in Amblydisca angulato; oculis fortiter prominentibus; pronoto

antice vix angustato, subparallelo, rugose punctato, ante scutellum leviter sinuato; tegminibus parallelis.

Allied to Aulacizes, which it closely resembles, except that the vertex of the head slopes upwards from the

eyes and is continued into a short upright process, which is excavate above and below, the excavation

being continued on the metopidium ; the metopidium, viewed from the side, forms a small angle, as in

Amblydisca ; the pronotum is scarcely narrower in front than behind, rugosely punctured, and only

slightly sinuate before the scutellum ; tegmina parallel; anterior tibiee not excavate.

1. Catorthorrhinus resimus, sp. n. (Tab. XIII. figg. 10, 10 a.)

Testaceus, capite pronotoque unicoloribus ; scutello testaceo, levissime sculpturato ; tegminibus flavo-testaceis

plus minusve distincte fulvo-notatis, apice griseo, subhyalino ; corpore subtus antice testaceo, abdomine

subtus albido ; pedibus testaceis vel fusco-testaceis.

Of a testaceous colour, with the abdomen underneath whitish, and the tegmina yellowish-testaceous, with more

214 HEMIPTERA-HOMOPTERA.

or less distinct, variable, fuscous, longitudinal bands, the most distinct being an oblique band reaching

from near the base to the suture about a third from the apex, where it takes a turn and joins the exterior

margin, the part behind being fuscous and subhyaline; sides of the breast and abdomen whitish ; legs

testaceous or fusco-testaceous.

Long. 12-13 millim.; lat. ad hum. 3-3} millim.

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

Our single example from Bugaba has the fuscous markings of the tegmina very

different from what they are in the specimens from the Volcan de Chiriqui, and they

are continued nearly to the apex; the process of the head, too, is scarcely so upright.

A specimen from the Volcan de Chiriqui is figured.

BASCARRHINUS, gen. nov.

Elongatus, postice latior, capite maximo subtus excavato ; metopidio inter oculos angusto, in processum longum

subtus profunde excavato, supra et ad latera canaliculatum ad apicem nonnihil dilatatum producto ;

oculis parvis; pronoto magno, subrugoso, lateribus postice dilatatis, basi sinuaté, angulis posticis late

rotundatis ; scutello magno; tegminibus ad apicem sensim dilatatis, remotius punctatis, venis leviter

exstantibus ; tibiis excavatis.

Elongate, with the head very large, subparallel before the eyes, which are small and then contracted in an

obtuse angle to the apex, from which there extends a long process, which is gradually dilated in front ;

the underside of the head and process are excavate, and the upperside of both is traversed by a channel,

the sides also of the process being channelled ; pronotum with the sides raised and dilated behind, sinuate

at the base, the posterior angles broadly rounded ; scutellum large ; tegmina gradually widened towards

the apex, with remote and rather large, but not deep, punctuation, the veins prominent; tibie excavate

on their outer margin.

This is a very distinct genus, and may at once be known from Rhaphirhinus, apart

from the general structure, by having the process of the head in the same plane with

the vertex, and not recurved, except almost imperceptibly at the extreme tip.

1. Bascarrhinus platypoides, sp. n. (Tab. XIII. fig. 11.)

Fuscus, vertice obscure testaceo, capite subtus flavo-testaceo, processu et spatio ad basim hujus subtus nigro ;

scutello testaceo variegato; tegminibus fuscis, subhyalinis, venis obscure rufescentibus; corpore subtus

testaceo ; pedibus fuscis, femoribus posticis rufescentibus, anterioribus et intermediis testaceis.

Lighter or darker fuscous, with the vertex and sometimes part of the pronotum obscurely testaceous ; under-

side of the rostrum and a space at the base dark, the rest of the underside of the head yellow-testaceous ;

at the base of the head and in the centre of the pronotum are two. small, light, longitudiral, testaceous

patches; scutellum dark, variegated with testaceous; tegmina subhyaline, with reddish veins; legs

somewhat variable in colour—in the type specimen fuscous, with the femora lighter, the posterior pair

rufescent ; underside testaceous.

Long. 18, sine processu 15 millim. ; lat. ad hum. 4 millim.

AULACIZES.

Aulacizes, Amyot et Serville, Hist. Nat. des Hémipt. p. 571 (1843).

The only characters given by Amyot and Serville to distinguish this genus from

AULACIZES. 215

Tettigonia are as follow :—“ Head prolonged in a cone in front of the eyes, with a

short, longitudinal, impressed furrow on the vertex.” Its range is, however, consider-

ably widened by Stal, and at present Awlacizes is taken as including a considerable

number of species which have the underside of the head convex and gibbous, or very

obtusely angled beneath, and the pronotum slightly narrowed in front and never

constricted behind the anterior margin, so that the latter appears broader than the

posterior margin, as in Phera and Oncometopia. The tibie are usually more or less

plainly sulcate, but sometimes the groove is very indistinct, and the insects do not

differ much as regards this character from Tettigonia; in these cases, however, the

slight projection before the eyes is very distinct, and the head is produced and

furrowed.

irroratis, apicibus hyalinis ; abdomine supra nigro; corpore subtus et pedibus dilute testaceis.

A comparatively broad and robust species, with the vertex of the head not strongly produced and rounded ;

eyes only slightly prominent; pronotum light castaneous, with a number of small whitish-testaceous

dashes and spots, which are also scattered more or less sparsely over the tegmina, the ground-colour of

which is testaceous or fusco-testaceous ; before the apex of the tegmina, which is hyaline, there is a row

of these spots; upperside of the abdomen black, the underside and legs testaceous.

Long. 11-12 millim.; lat. ad hum. 4~43 millim.

Hab. Mexico, Xucumanatlan, Amula, and Omilteme in Guerrero 6000-8000 feet

(H. H. Smith).

In our collection there is also a specimen from Purula, Vera Paz (Champion), which

may be an unspotted variety of this species.

An example from Xucumanatlan is figured.

In many of the Tettigoniide the colour of the upperside of the abdomen is variable,

being sometimes black and sometimes red in different specimens of the same species.

The tegmina are very often subhyaline, but they appear to be of an entirely different

colour when closed and when opened—in the present species when closed they are dark

fuscous, when opened they are castaneous or even light testaceous: this naturally causes

considerable confusion in descriptions, which are usually made from examples with

closed tegmina.

3. Aulacizes figurata, sp.n. (Tab. XIII. fig. 14.)

Precedenti similis, capite pronotoque flavo-testaceis vel albidis vel rufis, nigro- aut fusco-testaceis variegatis,

illo vertice leviter producto obtuse rotundato, hoe rugose punctato, basi fuscé; scutello figurato;

notatis, apice vix hyalino; abdomine supra toto nigro vel rufo aut testaceo ad medium nigro; corpore

subtus pedibusque dilute testaceis vel rufis.

Very like the preceding (A. piperata) in general appearance, but easily distinguishable by the constant pattern

of the head and pronotum, the ground-colour of which is yellowish, testaceous-whitish, or red, with

markings of the same or darker colour surrounded by dark lines; the pronotal markings extend almost

to the base, where they are terminated by a very irregular black line, the base behind this being fuscous ;

scutellum variegated; tegmina brown or fuscous (sometimes light brown), plainly pubescent, finely but

distinctly sculptured, with a number of small, irregular, whitish spots surrounded with black; in some

specimens they are scarcely visible, but where well marked the chief group forms an oblique line, starting

from behind the scutellum, on each of the tegmina; the apex is concolorous with the rest of the tegmina ;

upperside of the abdomen black, or red, or testaceous, with the central portion black; underside and legs

testaceous or reddish, the femora sometimes variegated with fuscous.

Long. 12 millim. ; lat. ad hum. 4 millim.

Hab. Mexico, Ventanas in Durango (forrer), Cuernavaca in Morelos (H. H. Smith ;

Bilimek, in Mus. Vind. Ces.), Chilpancingo, Tepetlapa, and Venta de Zopilote in

Guerrero (H. H. Smith); Guatemaua (Mus. Holm.).

There are also two specimens of this species in the Brussels Museum, without

definite locality.

We figure an example from Cuernavaca.

4, Aulacizes invidenda, sp.n. (Tab. XIII. fig. 15.)

Precedenti affinis, rufa vel testacea, capite pronotoque plus minusye nigro-variegato, hoc leviter ante oculos

minibus fuscis vel nigro-fuscis, rufo- vel testaceo-maculatis, apice subhyalino; pedibus et corpore subtus

cum colore macularum congruentibus.

Allied to the preceding species (A. figurata), but rather larger; head and pronotum red or testaceous,

variegated more or less distinctly with black; vertex short, obtusely rounded; pronotum rugosely

punctured; scutellum dark, with two light spots; tegmina dark, often with a bluish reflection, with

large, somewhat variable, red or testaceous spots, the chief group of which usually form a confluent

oblique band on each tegmen behind the scutellum; legs red or yellow, according to the colour of the

markings of the upperside. |

Long. 13-14 millim.; lat. ad hum. 44 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guaremata, Teleman in Vera Paz,

San Isidro, Zapote (Champion). |

The specimen from San Isidro differs somewhat from the rest, but can hardly be

referred to a separate species. An example from Teleman is figured.

maculis quibusdam tenuibus fuscis ; corpore rufo-testaceo ; femoribus testaceis, ad apicem fusco-annulatis ;

tibiis tarsisque nigris, his ad partem et genibus testaceis,

A rather broad and robust species, with the head shortly and bluntly produced ; head and pronotum whitish,

variegated with fuscous and testaceous ; scutellum testaceous, with two minute dark rings in front and

the apex fuscous; tegmina whitish, with the external border and apex testaceous, and with dots and

dashes of a dark colour, which also narrowly border the internal margin; abdomen with a fuscous spot

towards the apex; legs testaceous, the tibie and part of the tarsi and a ring before the knees fuscous.

Long. 12 millim.; lat. ad hum, 4 millim.

Hab. Mexico, Tierra Colorada in Guerrero 2000 feet (H. H. Smith).

6. Aulacizes isabellina, sp. n.

Elongata, sat angusta, isabellina ; capite parvo, vertice brevi, ante oculos late quadratim rotundato, cum pro-

perobscure rufa instructis, sat nitidis, levibus, postice sensim angustatis; corpore subtus obscure rufo ;

pedibus fuscis.

An obscure-looking species, of a dark dun colour, with the front parts, the underside, and a longitudinal fascia

towards the base of the tegmina obscurely crimson; head small, with short squarely rounded vertex ;

pronotum plainly narrowed in front, not sinuate at the base, almost smooth; scutellum large, depressed

in the middle ; tegmina rather shiny, almost smooth ; legs fuscous.

Long. 134 millim.; lat. ad hum. 4 millim.

Hab. Guatemata, Cerro Zunil 4000 feet (Champion).

A. isabellina appears to form a connecting-link between the preceding species (with

short, broad, obtuse heads) and the following, in which the head is more strongly

produced.

The above is Signoret’s synonymy, and I am somewhat doubtful of it; if he is right,

Walker’s name A. maculata ought to stand. Signoret, however, appears to have

named his insect afresh, as Walker had a nearly allied species, Ciccus maculatus, and

also a Diestostemma terminalis, and as the firstementioned author included all under

Tettigonia, it was impossible for him to let the synonyms stand; as it is, much confusion

is avoided by adopting Signoret’s name.

8. Aulacizes sparsa, sp.n. (Tab. XIII. fig. 17.)

A. piperate similis, sed major, vertice magis producto, triangulari, et corpore supra multo densius maculis

parvis asperso, facile distinguendus; capite nigro, maculis parvis testaceis; metopidio testaceo, nigro-

variegato; pronoto rugose punctato, basi ante scutellum leviter sinuata, hoc et tegminibus dense flavo-

testaceo aspersis; scutello nigro, macula magna ad basim flavescenti; tegminibus ad apicem haud

hyalinis ; corpore subtus dilute testaceo, abdomine ad medium nigro; pedibus testaceis.

Larger than A. piperata, which it resembles, and easily distinguished by its triangular head, the denser and

larger testaceous markings, which cover the whole upper surface, the large yellow spot on the scutellum,

and the opaque apex of the elytra; the markings on the pronotum, which is rugosely punctured, are more’

or less confluent, and the apex and extreme base are darker than the central portion; the general colour

is a rich castaneous brown, the underside (with the exception of a black line down the centre of the

abdomen) and the legs being light testaceous.

Long. 13 millim.; lat. ad hum. 4 millim.

A single female of this very distinct species was sent to me by Dr. Aurivillius among

some unnamed insects belonging to the Stockholm Museum.

Precedenti affinis, sed angustior et magis parallela, capite longiori, oculisque minus prominulis, corpore supra

multo densius maculis minutis testaceis irrorato.

Allied to the preceding (A. sparsa), but narrower and much duller, with the head larger and more pointed, and

the eyes less prominent ; pronotum less rugose ; upper surface much more thickly sprinkled with minute

whitish or testaceous spots, which are more separated on the pronotum; apex of the scutellum testaceous ;

metopidium mostly yellow ; chest and abdomen darker in the centre, lighter at the sides; legs reddish,

the femora variegated with testaceous.

Long. 13 millim.; lat. ad hum. 32 millim.

Hab. Mexico (Bilimek, in Mus. Vind. Ces.).

A specimen of this species has been sent to me from the Vienna Museum collection

as Tettigonia irrorata (Fabr.) (Ent. Syst. iv. p. 33; Sign. Ann. Soc. Ent. Fr. 1855, -

p. 59, t. 6. fig. 14 = Aulacizes rufiventris, Walk. List of Homopt. Ins. iii. p. 796),

which is a common Brazilian insect ; but it differs from a typical example of Signoret

sent with it in the shape of the head and eyes, narrower form, and different coluration,

and is, I think, without doubt distinct.

The type-form of this species is of a deep orange-red colour. The single specimen

in our collection, from Guatemala, and from which our figure is taken, is yellow, and

AULACIZES. 219

is somewhat broader in form ; but it appears to be too closely allied to be described as

a distinct species, at any rate upon a single example.

11. Aulacizes thunbergi. (Tab. XIII. fig. 20.)

Aulacizes thunbergii, Stal, Stett. ent. Zeit. xxv. p. 79 (1864) ’.

GuateMaLa, Lanquin, San Juan, Chiacam, Balheu, and San Gerénimo in Vera Paz

(Champion); Nicaragua, Chontales (Janson).

This species varies considerably in coloration. It is a somewhat elongate insect, with

the head considerably produced, of a dark colour, with a number of large variable and

more or less confluent spots, which are either bright crimson, scarlet, or yellow; these

are sometimes much reduced, but often form the greater part of the ground-colour.

It would be quite impossible to recognize the example belonging to the Vienna

Museum, which I have before me, and which was presented by Stal himself, by means

of his description above referred to}.

An example from Chiacam is figured.

brunneis, subhyalinis, perobscure vittatis; corpore supra fusco vel fusco-rufescenti, subtus testaceo ;

pedibus dilute testaceis.

Elongate, parallel, with the head and pronotum greyish or yellowish-testaceous ; vertex with two small black

markings at the apex and two at the base, the former occasionally absent, and with a deep short furrow

in the centre; pronotum with the base dark and with four constant small black spots arranged longi-

tudinally just before the apical border, finely rugose longitudinally; scutellum large, shining, fuscous ;

tegmina smooth, semitransparent, somewhat variable in colour, with more or less distinct lines of darker

bands, which are often scarcely traceable, the apex and the suture broadly before the apex more or less

conspicuously darker than the ground-colour ; upperside of the abdomen more or less dusky, the underside

and legs light testaceous.

Long. 14-15 millim.; lat. ad hum. 3-33 millim.

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

This species is rather closely allied to A. amblardi, bat may easily be known by the

longer and narrower head, and by the shape of the metopidium, which is convex and

rounded for some distance, and then terminates in a very blunt angle. It might,

perhaps, be placed under the genus Amblydisca, but its general affinities appear to be

much more towards Awlacizes.

A specimen from Bugaba is figured.

This species is not represented in our collection; it is allied to A. amdlardi, but is

broader and has the head shorter and more truncate, besides being differently coloured.

15. Aulacizes insignior, sp. n. (Tab. XIII. fig. 22.)

Major, lata, fusca, rufo-variegata; vertice elongato, lato, obtuse rotundato, impresso, oculis prominulis ; pronoto

antice distincte angustato, fortiter rugose punctato, basi fortiter sinuata, utrinque ad medium impresso,

fusco-testaceo, indistincte rufo-variegato; scutello magno fuscato; tegminibus distincte punctatis, ad

apicem reticulatis, fuscis, irregulariter rufo-vittatis ; pedibus fuscis.

A large and conspicuous species ; head long, the underside flatly horizontal, if viewed from the side; vertex

long, produced in a large triangle, with the apex bluntly rounded, impressed in front and broadly sulcate

behind ; eyes prominent; pronotum distinctly narrowed in front, strongly impressed in front and at the

sides, rugosely punctured, deeply sinuate at the base; tegmina distinctly and closely, but not strongly,

punctured, fuscous, with a broad irregular red band extending obliquely from the scutellum to the sides,

and a second band extended across the surface at about a third before the apex, the apical third being

fuscous, subhyaline, and reticulate; legs fuscous.

Long. 17 millim.; lat. ad hum. 5 millim.

Hab. Panama (Boucard).

I have described this species with some hesitation, as the type-specimen is a poor

one and imperfect, but in size and structure and general appearance it differs greatly

from the other members of the genus, and is easily recognizable ; A. insignior may

‘very probably have to be removed from Aulacizes.

PHERA.

Phera, Stal, Kong. Svensk. Vet.-Ak. Hand]. Band viii. no. 1 (Hemipt. Fabr. ii.), p. 60, nota (1869).

I have regarded this genus of Stal as including certain species which have the head

produced in a more or less elongate triangle, the vertex plainly furrowed, and the

pronotum with the sides quite parallel or, if anything, broader at the apex than at -

the base; the two veins of the clavus are sometimes distinct, but appear often to

coalesce for the greater part of their length, and divide into a fork at each end.

I have only seen one example of this insect, which, apart from the characters of the

head, appears to be closely related to certain species of Aulacizes. St&l compares it to

P. centrolineata, Sign., to which, superficially, it seems to bear a very slight resemblance,

being much broader and more robust. |

This is the largest species of the genus. The single specimen from Panama is a

very large example, 20 millim. in length, and has the front of the head and the basal

two-thirds of the pronotum red, and the legs clear red; it does not, however, appear

to be anything more than a variety.

I believe that the above synonymy will prove to be correct, as 7. vitripennis is

mentioned by Signoret ? as a common species in Brazil and California, and therefore

is sure to occur in Central America, and Walker's two species, as well as 7. ichthyo-

cephala (of which there are specimens from Mexico in Signoret’s collection in the

Vienna Museum), appear to agree well with the description and figure, allowing for the

variation which appears to be present in many of the Tettigoniide. This variation in

colour is very evident in a series in our collection from Presidio, Mexico. A specimen

from Atoyac is figured.

I have not seen an example of this species, which apparently bears a superficial

resemblance to the male of P. centrolineata and is not much larger than that insect ;

the head, however, is much blunted at the apex and less deeply furrowed, and the eyes

are somewhat less prominent.

long black head, which is pointed and deeply sulcate.

I have had specimens of this species sent to me among undetermined material

belonging to both the Vienna and Stockholm Museums. The general colour of the

tegmina, when unfolded, is a tawny-reddish, with broad hyaline apex; the colour,

however, appears to be to a certain extent variable, and the specimen from Dos

This insect is intermediate between P. luciola and P. centrolineata. It is probable

that P. téarata is nothing more than a variety of the latter species, but as one example

only has been seen Ido not feel justified in sinking the name as a synonym. Stal

himself speaks of it as “P. centrolineate maxime affinis, capite nonnihil longiore,

(Schumann), Oaxaca (Mus. Brit.).

The male is black, with a conspicuous white line on the vertex, whereas the female

(Ciccus nigriluz, Walk.) has the centre of the pronotum broadly, and the scutellum,

reddish or orange-red. I have examined a considerable number of specimens and find

that the insect is invariably coloured as described when mature ; occasionally in the

female the whole head, pronotum, and scutellum are of a reddish-orange colour. The

single example from Orizaba is a male, and is very light-coloured, but, so far as I can

judge, this is due to immaturity.

A specimen from Chilpancingo is figured.

Allied to the preceding (P. centrolineata), but easily distinguished by the shorter, broader, and much more

obtuse head, which, viewed from the side, is much thicker and shows no inclination to become reflexed

upwards; the sides and anterior margin of the metopidium are reddish-yellow, whereas in P. centrolineata

they are black; the pronotum is more strongly and rugosely punctured than in the latter species ; and

the spots on the margin of the tegmina, instead of being black or fuscous, are of a dark crimson colour

in the female ; moreover, the male appears to be coloured like the female, with the exception of these

spots, which are fuscous.

This is a distinct but obscure species: I found it mixed in our collection with

14. Phera lacerta, sp.n. (Tab. XIV. fig. 8.)

Angusta, parallela, nitidior; capite magno, elongato, triangulari, apice verticis obtuse angulato, oculis magnis

A narrow, parallel, shining species, with a large elongate triangular head, and large prominent eyes;

metopidium black, with the sides and front testaceous, the front part with a narrow black line in the

centre; vertex and pronotum testaceous, with dark lines and patches, the lines on the front of the

former arranged at the sides very plainly in segments of concentric circles; pronotum considerably

shorter than the head, rugosely punctured; scutellum large, fuscous, with yellow markings; tegmina

transparent, smooth and shining, with a large elongate patch at the margins before the apex and the

marginal vein bright red; underside more or less fuscous in the middle, testaceous at the sides ; legs

testaceous, with the tibice and tarsi more or less infuscate on their upperside.

Long. 11 millim.; lat. ad hum. 2 millim.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith).

There is a specimen in our collection, from Ciudad in Durango, Mexico, 8100 feet

(Forrer), which is closely allied to this species, but differs in having the vertex of the

head a little shorter and more blunt at the apex, the dark markings of the head and

pronotum more pronounced, and the tegmina less hyaline and without the red patches ;

it very probably belongs to a separate species, but at present I prefer to treat it as a

variety.

The typical form is figured.

Closely allied to Phera in shape and general appearance, but distinguished by having the vertex of the head

without sulcation.

The insect on which I have formed this genus at first sight appears to belong to

Phera, but it must evidently be separated from the latter genus, nor can it well be

Stal, but in others it does not answer to his description.

Of a bright orange-colour, with part of the underside and the legs light testaceous, the upperside of the

abdomen partly brownish at the sides, and the extreme margins ef the head, pronotum, and basal half

of the tegmina, as well as the suture very narrowly, black; there are also a few black markings on the

vertex, which is shallowly excavate behind the middle and very slightly and gradually reflexed in front ;

head long, triangular; eyes rather long and not very prominent; pronotum finely sculptured, with two

small dark markings at the base; scutellum large, with two very small dark markings at the base

meeting those on the pronotum ; tegmina small and shining, hyaline.

CYRTODISCA.

Cyriodisca, Stal, Kongl. Svensk. Vet.-Ak. Handl. Band viii. no. 1 (Hemipt. Fabr. 11.), p. 60, nota

(1869).

This genus was formed by Stal to include the Tettigonia major of Signoret ; it is

distinguished from Phera by having the head distinctly broader than long and plainly

shorter than the pronotum, and from Oncometopia by the subtriangular and more

strongly impressed head, which usually has the longitudinal line at the base deeply

marked; the two veins of the clavus are usually separate, but this character, which

Stal mentions as one of the characteristics of the genus, is variable, and in a specimen

before me the two veins cross and form an irregular X; the tegminaare reticulate behind

the middle, the reticulations being bounded by rather fine but distinct venation.

The usual colour of this insect in collections is a uniform lighter or darker fuscous

or reddish-brown, but lighter specimens occur with the front parts finely mottled

and the anterior margins of the tegmina dark: it is probable that the colour fades

considerably after death, as traces of the mottling are found on most of the fresher

specimens; at all events, these lighter examples appear at most to be a variety.

A fresh and brightly-coloured specimen from Tierra Colorada is figured.

ONCOMETOPIA.

Oncometopia, Stal, Kongl. Svensk. Vet.-Ak. Handl. Band viii. no. 1 (Hemipt. Fabr. ii.), p. 60,

Méthod. x. pp. 610, 611 (1825) ].

This genus is characterized by having the head short, usually simply rounded in

front, and never distinctly produced in an isosceles triangle, as in Phera; the vertex in

the majority of the species is without any trace of a furrow, and, at most, there is a

small and very inconspicuous longitudinal impressed line at the base; the head, viewed

from the side, is thick and rounded, and convex beneath, and the anterior tibie are

sulcate. The species are large or moderate-sized, sombre-coloured insects, and they

have been usually referred to Proconia, but Lepeletier and Serville’s types of their

two divisions of this genus are respectively Tettigonia cristata (Fabr.) and T. excavata,

Lep. et Serv.; the latter is a well-known and very variable Brazilian species, which

has the vertex produced in an elongate triangle and deeply and broadly furrowed, and

the anterior tibiz dilated and not sulcate. The two veins of the clavus are variable,

being either distinct and subparallel, or closely approaching one another, or else

coalescing into one thick vein, which divides into two for a longer or shorter space at

the base and apex.

In general appearance this species much resembles Cyrtodisca major, but may

easily be known from it by the more prominent eyes and the general shape of the

head, as well as by the obscure fuscous markings on the tegmina. Stal, apparently

accidentally, has omitted the species from his “ Hemiptera Mexicana” (Stett. ent.

Hab. Mexico (Mus. Berol.').

I have not seen a specimen of this insect, which differs from the preceding species,

according to Signoret, in being considerably smaller (length 14, as against 18 millim.),

and in having the tegmina entirely reddish-hyaline and margined with yellow; the

tegmina, moreover, are smoother, and not rugose as in O. rubiginosa.

8. Oncometopia interjecta, sp.n. (Tab. XIV. fig. 12.)

Oblonga, parallela, fusco-brunnea, tegminibus nigris, apicibus late hyalinis ; capite equilateraliter triangulari,

vertice obtuso, oculis sat prominentibus ; pronoto nitido, leviter transversim rugoso; tegminibus remotius

et rugosius punctatis, venis crassis, elevatis ; corpore subtus pedibusque fusco-violaceis.

Oblong, parallel, the head and pronotum fuscous-brown, the tegmina black, with the apex broadly and clearly

hyaline ; head equilaterally triangular, with the vertical angle obtuse, rounded ; pronotum shining, finely

rugose; scutellum large, fuscous or variegated with testaceous; tegmina rather sparingly and strongly

punctured, with thick raised veins; underside and legs of a fusco-violaceous colour, the latter darker,

sometimes nearly black; last ventral segment of the female emarginate, with the side-lobes short.

Long. 12 millim.; lat. ad hum. 3 millim.

Hab. Panama, Bugaba (Champion).

This species, at first sight, appears to be allied to Phera vitripennis, but it has a

much shorter head. Although the head is longer and more triangular than is usual in

Oncometopia, the insect possesses all the other characteristics of the present genus; it

may, perhaps, be regarded as a connecting-link between Phera and Oncometopia.

This seems to be a very widely distributed insect ; it varies considerably in size, but

intermediate forms occur. The head and pronotum are often of a lighter colour than

the tegmina, and in some cases (7. herpes, Sign.) there are a few minute light spots

sprinkled over the tegmina.

legs testaceous, .

Male. Narrower and more parallel, more darkly coloured, with the tegmina fuscous, sprinkled very sparingly

with testaceous spots and with obscurely lighter patches towards the margins.

Female. Broader, more robust, and less parallel, with the tegmina fuscous, thickly mottled with irregular

testaceous spots, which cover a considerable portion of the ground-colour, and in parts more or less

coalesce; apical segment of the abdomen not broadly but rather deeply emarginate, with a raised line

before the central portion, and with the side-lobes rather long and rounded.

The male of this species is scarcely distinguishable from the Tettigonia herpes of

Signoret, which is synonymous with 0. obtusa (Fabr.); it has, however, the spots

somewhat different. The female is one of the most distinct insects 1 have seen in

the group.

6. Oncometopia tartarea. (Tab. XIV. fig. 15.)

Phera tartarea, Stal, Stett. ent. Zeit. xxv. p. 78 (1864) *.

Hab. Mexico (Sallé, in Mus. Holm.'; Mus. Vind. Ces.), Omilteme 8000 feet and

Xautipa in Guerrero (H. H. Smith).

I am very doubtful as to this species: it can only be distinguished by the shape of

_ the terminal ventral segment of the female, which Stal describes as ‘“ medio leviter

trisinuatum ante sinus leviter subelevatum et ibidem utrinque dente parvo instructum.”

The insects I have referred to O. tartarea appear to agree in this respect, but the shape

of the last segment of the female appears to vary. In O. obtusa this segment is simply

emarginate, with the central space raised, and furnished in the middle with a longi-

tudinal raised line, and with two folds at the side caused by the raised portion; the

side-lobes of the segment vary in length, the folds, however, at the sides appear

sometimes to split, and in this case the segment presents quite a different appearance ;

the longitudinal raised central line is sometimes depressed (this, however, often happens

from other causes in dried specimens), and the central emarginate portion becomes

sinuate in the centre and apparently more or less cut out at the side, this being very

evident in three specimens in our collection from Cuesta de Misantla, Mexico, evidently

belonging to the same species, one of which presents the normal form of the segment

and the other two show the differences mentioned. It would seem, then, that the

transition to the shape of the segment of the present species might easily take place,

and if such is the case 0. fartarea must be regarded as synonymous with O. obtusa, as

230 HEMIPTERA-HOMOPTERA.

Stal’s other characters do not appear to be constant. He speaks of the vertex of the

head, for instance, as being furnished with two testaceous spots at the base, but these

are only present in some specimens, and in one example, a female, in which they are

very conspicuous, and in which the other characters agree with Stal’s description, the

last segment of the abdomen is abnormally shaped, being deeply and narrowly raised

in the centre, with the central portion forming a small raised horizontal prominence ;

in fact, if the formation of the segment is to be taken as a specific character, this

specimen might well be referred to a different species, and yet it must be treated, I think,

as specifically identical with the other examples from the same locality (Omilteme).

It is probable that the Tettigonia funebris of Signoret, from California, is identical

with O. tartarea, as there is a specimen in the Vienna Museum labelled with both

names ; if such be the case, Signoret’s name must be substituted, unless both are

finally referred to O. obtusa after the examination of a larger amount of material.

A specimen from Omilteme is figured.

7. Oncometopia fuscipennis, sp. n. (Tab. XIV. fig. 16.)

O. obtuse affinis, sed brevior et latior, nigra; capite et pronoto fuscis, obscure variegatis, illo lato, hoc longitudine

sesqui-longiori, rugose punctato; scutello magno; tegminibus usque ad apicem fusco-hyalinum fusco-

brunneis; corpore subtus pedibusque fusco-piceis, illius marginibus dilutioribus, nonnunquam flaves-

centibus.

Very like O. obtusa, but shorter and broader in proportion, black, with the front parts more or less obscurely

variegated with reddish-fuscous ; head short and broad; tegmina of a fuscous-brown colour, with the

apex, which is usually clear hyaline, also fuscous, though transparent, and with a more or less distinct

transparent spot (sometimes obscure) about the middle ; sides of the body lighter, sometimes light yellow,

and probably of this colour in all specimens in life.

Precedenti valde affinis, sed tegminibus nigro-fuscis quatuor maculis lete rufis instructis precipue distin-

Very closely allied to the preceding (0. fuscipennis) and, like it, differing from O. obtusa in its shorter and

proportionately broader form; the tegmina, however, are darker, and at the base and outer margin of

each, towards the apex, there is a bright red patch, which gives the insect a very distinct appearance ;

the sides of the body are a light testaceous-yellow.

Long. 14 millim.; lat. ad hum. 4 millim.

I have also referred one or two other specimens doubtfully to this species, as they

resemble it in shape and in the colouring of the tegmina, but have the red spots

indistinct or absent. They are all from the same locality.

abdomine nigro, ad latera dilutiori ; pedibus piceis.

A rather broad species, with the head and pronotum black and shining, obscurely variegated with red, the

former somewhat depressed in the middle of the vertex, the latter rugose ; scutellum large, smooth, and

shining, reddish behind ; tegmina scarlet, with two irregular bands in front, formed of four large blotches

connected by a narrow strip, a band behind the middle reaching across the tegmina, and the suture,

black ; the apex of the tegmina is fuscous and scarcely transparent; sides of the breast yellowish-white ;

abdomen black, a little lighter at the sides, that of the female with the last segment rather deeply and

squarely emarginate, and furnished with an impression on each side before the emargination, and the

side-lobes moderately large and bent towards one another; legs pitchy.

There is a very large series of this common American insect in our collection, and,

although the extreme forms are very different, yet I am quite unable to separate them

satisfactorily into species. As a rule, the pattern of the pronotum, which is usually

232 HEMIPTERA-HOMOPTERA.

traceable, forms a very good method for roughly distinguishing the species; but in

some cases it is very obscure. The characters of the sexes appear to be fairly constant,

the last abdominal segment of the female being squarely and more or less deeply

emarginate, with the side-lobes longer or shorter in proportion: in two female specimens,

however, before me, from the same locality, one has the segment broadly emarginate

in almost a crescent, and the other has it narrowly and squarely emarginate. The

examples differ very much in size, and also in the size and shape of the head, which in

some cases is very large as compared with that of the ordinary type-form ; this is

particularly noticeable in a series from Chontales, Nicaragua. The colour also varies

considerably, the tegmina being green, reddish, or fuscous, and the head and pronotum

being also variable in this respect.

The types of Proconia badia, P. scutellata, and P. plagiata », Walk., were from

unknown localities; and Fabricius > ® merely gives “ America” for his Cicada orbona.

We figure two specimens—one from Atoyac and one from Chontales.

Allied to O. undata, from which it differs in the colouring and pattern of the pronotum, and especially in the

shape of the last ventral segment of the female; front parts yellow, marked regularly with narrow black

The type-form has the front parts bright red, without any markings; at most, there

is a narrow longitudinal black line on the vertex, and an obscure dark marking or two

on the metopidium and scutellum. The colour varies in distinctness, and in one or

two specimens has faded to testaceous; this is probably the case with many of the

species. O. rubescens may be an extreme form of O. undata, but there seems enough

difference to keep it at present as a distinct species.

An example from David is figured.

This and the following species are closely allied to Phera aurea, from which they

differ in the short rounded head. Walker’s type was from an unknown locality !.

An example from Teapa is figured.

16. Oncometopia anceps, sp. n. (Tab. XIV. fig. 26.)

Allied to the preceding (O. speculifera), but larger and stouter, of a brown or fuscous-brown colour, with the

head and thorax marked with reddish-yellow or whitish; head short, broad, with large prominent eyes ;

pronotum with three longitudinal abbreviated reddish-yellow or whitish bands, which are usually more

or less broken up into spots; scutellum with the centre, apex, and extremities of the base yellowish-red or

whitish, very finely sculptured; tegmina smooth and shining, subhyaline, gradually narrowed to the

there are one or two rather conspicuous, although small, yellowish or whitish spots, and often two more are

present behind these, and other minute spots on the veins ; underside and legs testaceous or pitchy-brown.

A rather short species, with the head, pronotum, and scutellum black, the head, scutellum, and the anterior

edge of the. pronotum with obscure fuscous-red markings, the pronotum rugosely punctured; tegmina

hyaline, fuscous-yellow or fuscous-brown, with an irregular yellow spot before the apex, bounded before

‘the apex, which is vitreous, by a black fascia, which is continued for a short distance upwards at the

suture ; underside and legs pitchy, the sides of the body light testaceous-yellow.

Hab. Mexico (Mus. Berol.').

I have not seen an example of this species, which, to judge from the description,

appears to be intermediate between Phera and Oncometopia, having the rounded head

of the latter, but furnished with a longitudinal furrow as in the former. Signoret

describes it as yellow, but, according to his figure, it is an obscure brown insect, with

the front parts and apex of the tegmina lighter.

TETTIGONIA. 235

TETTIGONIA.

Tetigonia, Geoffroy, Hist. abrég. des Ins. i. p. 429 (1764).

Tettigonia, Fabricius, Gen. Ins. p. 173 (1776) ; Signoret, Ann. Soc. Ent. Fr. 18538, p. 14.

This genus contains a very large number of species, many of which are among the

most highly coloured and conspicuous of all insects; they have for the most part a

facies of their own, but it is hard to define the characters with any certainty. The

Tettigonie may be, as a rule, distinguished from their allies by the smooth and more

or less rounded anterior tibize, which are rarely flattened or sulcate, and by the absence

in most of the species of the smooth projections at the sides of the head in front of the

eyes, these being very conspicuous in Aulacizes, &c. It is possible that the genus may

at some future time be divided, but it seems impossible to do this satisfactorily in the

present state of our knowledge. The shape of the head is very variable, and on this

character two or three groups might be separated off; but intermediate forms would

render these very doubtful, and the same might be said if other characters were adopted.

I have already alluded to the unsatisfactory nature of Signoret’s classification of the

whole group, and of Stal’s dichotomous tables.

1. Tettigonia burmeisteri.

Tettigonia burmeisteri, Sign. Ann. Soc. Ent. Fr. 1853, p. 28, t. 2. fig. 3’.

Hab. Mexico! 2.

This appears to be the only Central-American species belonging to Signoret’s first

group of the genus Tettigonia ; he at first classed the insects belonging to it under a

different name, Dilobopterus, which ought almost certainly to be retained. It is

distinguished by a considerable dilatation of the cubital or claval portion of the

wing *. I have not seen a specimen, but it appears to be rather a small insect

(length 8 millim.), with dark head and pronotum, and light yellow tegmina, the apical

third of the latter being subhyaline and smoky.

applies the same terms to the wings.

Var. trilineata, nn. (Tab. XV. fig. 1.)

Tribus lineis albidis tegminum, lineaque albida centrali pronoti distinguenda.

Tegmina with three narrow white lines, the third being situated just opposite the apex of the scutellum ;

there is also present in some specimens an almost semicircular, more or less distinct, white line, stretching

from the two ends of the white basal line across the middle of the pronotum. |

Rather larger and duller, without trace of a fascia on the tegmina, and with the thorax almost unicolorous

black, the basal white line being only faintly indicated ; the elytra with a bluish reflection.

Hab. Costa Rica, Caché (Rogers).

It is possible that this may belong to a distinct species, in which case the name

T. deficiens can stand, as it has not yet been applied to any member of the group.

A specimen of the var. trilineata from Bugaba is figured.

Rather closely allied to the var. trilineata of T. ruficeps, but on the average smaller, with the head black, the

metopidium being bordered with white and with two conspicuous white longitudinal bands extending for

nearly its whole length, but not touching either margin; pronotum black, smooth, and very shining,

rather broadly bordered with white; tegmina shining black, with three rather broad equidistant white

bands, of which the apical one is interrupted at the suture ; femora bright red; tibie and tarsi more or

less pitchy or pitchy-testaceous.

the eyes; pronotum dark in front, dark reddish-brown behind, with two large yellow spots touching the

margins; tegmina yellowish, with the front part dark reddish-brown, this colour continued behind, and

gradually narrowed to a point at the suture beyond the middle, where it joins another broad dark band ;

on the anterior dark patch there are four bright yellow spots, two in front, larger, and two behind,

Similar in shape to the preceding (7. chiriquensis), of a tawny-yellow or obscure orange-colour ; head yellow,

with a broad transverse band across the vertex, and two short lines proceeding transversely from

the ocelli, black ; pronotum and scutellum deeper yellow, the former convex and smooth, with the anterior

T. lateralis seems to be a very wide-spread and somewhat variable insect. I have

seen specimens of it from the Vienna Museum, as well] as others in the British Museum,

and though they differ slightly from the Central-American examples I think the latter

must be treated as a local form of the same species. The light line on each side of

the under surface of the body continued to the head, though sometimes broken up and

absent, seems to be characteristic of 7. costalis. It may perhaps be of use to give a

description of our insect :—

Short and robust, with the head and pronotum black, speckled more or less thickly and distinctly with

testaceous or whitish spots; head large, rather short, triangularly rounded, with large and prominent

eyes; pronotum short, more or less distinctly rugose, with the base very gently and broadly sinuate ;

scutellum large, almost smooth or very slightly sculptured, dark, with light spots or markings; tegmina

leaden-coloured or leaden with a reddish tinge, with the veins thick and dark, the colours often extending

a little on either side of the veins, which are continued to the apex, the apex itself being hyaline; under-

side of the body light at the sides, the light colour extending to the head, dark or reddish-brown marked

with testaceous in the centre; legs pitchy-testaceous or pitchy, the femora red, sometimes partly dark and

marked with testaceous spots. Long. 6-7 millim.; lat. ad hum. 3 millim.

A specimen from the Volcan de Chiriqui is figured.

20. Tettigonia punctulata. (Tab. XV. fig. 19.)

Tettigonia punctulata, Sign. Aun. Soc. Ent. Fr. 1853, p. 345, t. 9. fig. 15°.

Hab. Mexico (Sallé), Presidio de Mazatlan (Forrer), Chilpancingo, Venta de Zopilote,

Tepetlapa and Amula in Guerrero, Cuernavaca in Morelos (H. H. Smith).

The shape of the head appears to differ somewhat in this species, and the colour is

at times variable. The specimens from Chilpancingo, with one or two exceptions, are

brighter and have the head narrower and longer, and but for intermediate examples

from the same locality they might be regarded as belonging to a separate species.

Signoret apparently described his species on one example, for he says, “labdomen

manque”: this part of the insect is bright red above and below. He figures an insect

of the shape of the variety from Chilpancingo, with the markings of the head and

pronotum of the more widely distributed form, which are slightly different, especially

those of the head.

There is a considerable series of the species in our collection. A specimen from

Chilpancingo is figured.

21. Tettigonia germana, sp.n. (Tab. XV. fig. 20.)

T. punctulate affinis, sed major ; capite breviori, hoc cum pronoto et scutello dilutioribus, magis confluenter

notatis, scutello ad apicem conspicue testaceo; tegminibus longioribus haudquaquam lineatis, rubris,

TETTIGONIA, . 243

colore dilutiori et obscuriori plus minusve distincte variegatis, apice late hyalino ; alis fumosis; abdomine

flavo; corpore subtus testaceo; pedibus piceis.

Allied to 7’. punctulata, but, as a rule, larger, with the front parts more confluently marked and lighter, and

the head broader and shorter; scutellum variegated in front, the apex plain testaceous ; tegmina red,

mottled obscurely with lighter and darker colour, and without any trace of a linear arrangement of the

colour such as is always present in 7’. punctulata, the apex broadly hyaline; wings smoky; abdomen

yellow ; underside testaceous ; legs pitchy or pitchy-testaceous.

Long. 11-12 millim.; lat. ad hum. vix 3 millim.

Hab. Mexico (Sallé; Mus. Vind. Ces.; Mus. Holm.), Cuernavaca in Morelos,

Xucumanatlan, Chilpancingo, Amula, and Omilteme in Guerrero, Atoyac in Vera

Cruz (H. H. Smith), Orizaba (Bilimek, in Mus. Vind. Ces.).

I have found specimens of this species among the unnamed material sent me from

the Stockholm and Vienna Museums; it is very distinct, but has apparently been

overlooked.

The examples from Cuernavaca, Chilpancingc, and Atoyac have the markings much

coarser and more confluent, but they do not appear to be structurally different from

the others.

We figure a specimen from Xucumanatlan.

22. Tettigonia preterita, sp.n. (Tab. XV. fig. 21.)

Nigra vel fusca, testaceo plus minusve notata; capite producto, triangulari, oculis vix prominulis ; pronoto

convexo, duabus maculis distinctis et aliis notis testaceis; scutello nigro, testaceo-variegato, postice

testaceo; tegminibus rubris, apice hyalino, fere concoloribus sine lineis vel notis obscurioribus ; abdomine

supra rufescenti; corpore subtus plerumque nigro, testaceo-variegato; pedibus testaceis, ad partem

nigricantibus.

Black or fuscous, with testaceous markings, and two conspicuous similarly coloured spots, one on each side of

the central line of the pronotum ; tegmina crimson, without distinct lines or darker markings, hyaline at

the apex ; abdomen red or brownish above, reddish in the middle beneath, the rest of the underside dark,

with testaceous markings ; legs testaceous, partly black or pitchy.

Long, 9 millim.; lat. ad hum. 2 millim.

Hab. Mexico, Xucumanatlan and Omilteme in Guerrero 7000 to 8000 feet

(H. H. Smith).

After working through a large number of examples of the species of Tettigonia with

red tegmina, which form the most obscure and difficult group of the genus, I came at

last to three specimens which could not be referred to any of the others: two of these

I have here described under the name TZ. preterita. ‘They differ inter se in the

markings of the head and pronotum, but appear to be structurally alike. The present

species is allied to 7’. punctulata, from which it differs in having the tegmina wider at

the apex and differently coloured, as well as in the quite different markings of the fore

parts; from 7’. germana they may be distinguished by the shorter elytra and the longer

and more triangular head.

The specimen from Xucumanatlan is figured.

23. Tettigonia monticola, sp. n. (Tab. XV. fig. 22. .

Brevis, robusta, nigra, testaceo sparsim notata; capite producto, triangulari, oculis vix prominulis ; pronoto

antice fortius semicirculariter impresso, duabus maculis et aliis notis testaceis ; scutello postice testaceo ;

tegminibus amplis, latioribus, leviter sed distincte sculpturatis, rubris, corio macula albidé magna irregulari

ante medium instructo, apice vix hyalino; alis opacis, albido-fumosis; abdomine supra nigro, apicem

versus testaceo, subtus fusco, testaceo minute irrorato ; pedibus piceis.

Ashort and stout species, black, with testaceous markings; head produced, triangular, eyes scarcely prominent;

pronotum with a strong impression in front and one on each side, with two testaceous spots as in the

preceding species (7’. preterita) and other markings ; tegmina ample, broad in proportion to their length,

crimson, with the upper and lower borders very narrowly dark for part of their length, and with minute

whitish markings; corium with a large irregular white patch before the middle; the sculpture is fine

but distinct ; wings smoky-white ; abdomen dark above, testaceous towards the apex; underside dark,

with minute testaceous spots; legs pitchy, in part lighter.

Long. 7 millim.; lat. ad hum. 2 millim.

Hab. Mexico, Sierra de las Aguas Escondidas in Guerrero 9500 feet (H. H. Smith).

This insect may easily be known by its short broad tegmina and the conspicuous

white patch on the corium; it was captured at the highest altitude from which we

have received any specimen of the genus and may perhaps be a mountain-form of one

of the allied species.

24. Tettigonia mediolineata, sp.n. (Tab. XV. fig. 23.)

Brevis, flavescens, nigro lineata et figurata; capite sat producto, triangulari, oculis modice prominulis ; pronoto

convexo, levi, lined, laté media flava a basi verticis usque ad apicem scutelli et interdum ad apicem

verticis continuata, aliisque ad latera plus minusve curvatis instructo: tegminibus rufis, apice hyalino,

marginibus anguste et sutura clavali fuscatis; alis fumosis; abdomine supra nigro, subtus nigro, ad

partem albido vel testaceo; pedibus testaceis, nigro- vel piceo-variegatis aut lineatis.

Short and rather thick, yellow, lined and figured with black; head somewhat produced, triangular, eyes

moderately prominent; pronotum convex, smooth, with a broad central yellow line, which is continued

from the base of the vertex to the apex of the scutellum and sometimes to the apex of the vertex, and

with two other more or less regular curved lines on either side; tegmina red, hyaline at the apex, with

the margins narrowly and the claval suture fuscous, and the space next the suture and part of the intra-

venal spaces lighter; wings dark smoky; abdomen black above, underside black, with the segments

marked with whitish; pygofer yellow; legs yellow or testaceous, marked or broadly lined with black.

Long. 8 millim.; lat. ad hum. 23 millim.

Hab. Mexico (Mus. Vind. Ces.; Boucard, in Mus. Holm.), Ciudad and Ventanas in

Durango (Forrer), Omilteme in Guerrero 8000 feet (H. H. Smith).

This species varies somewhat in size and colour, the broad central line being

continued either from the base or apex of the vertex to the apex of the scutellum ; in

the former case the markings on the head are more distinct. The tegmina have the

lighter band inside the costal margin more or less distinct, and sometimes (as in the

case of two specimens in the Stockholm Museum) it is broad and clear light yellow,

and extends from the shoulders almost to the apex. In the Vienna Museum there is

a specimen, labelled “ Bilimek, Mexico,” with the broad central line very distintc, but

TETTIGONIA. 245

with the markings of the tegmina rather resembling those of 7. punctulata, but it

evidently belongs to this species.

We figure an example from Omilteme.

25. Tettigonia magica. (Tab. XV. figg. 24; 25, var.)

Tettigonia magica, Stal, Stett. ent. Zeit. xxv. p. 77'.

Hab. Mexico (Mus. Holm.! & Mus. Vind. Ces.), Chilpancingo and Rincon in Guerrero

(H. H. Smith), Cuernavaca in Morelos (H. H. Smith, Bilimek), Orizaba (Bilimek,

H. H. Smith, & F. D. Godman).

This is a very easily recognized species, with the head rather produced and narrower

than in several of the allied forms, and the markings of the head, thorax, and scutellum

distinct and constant. I have found several specimens of it among unnamed material

belonging to the Vienna Museum. As a rule, the tegmina have the ground-colour

red, but a common variety has the whole ground-colour greenish-testaceous, without

any red on the insect. |

A specimen from Chilpancingo and a variety from Orizaba are figured.

26. Tettigonia consobrina, sp. n. (Tab. XV. fig. 26.)

Fusco-rufa, maculis parvis dilutis regulariter aspersa; capite producto, haud triangulari, antice rotundato,

oculis prominulis; pronoto sat longo, basi vix sinuaté; scutello ad medium impresso; tegminibus apicem

versus angustatis ; abdomine supra fusco; corpore subtus rufescente ; pedibus rufo-brunneis.

Dark fuscous-red, regularly sprinkled from the metopidium to the apex of the tegmina with small light spots,

which are testaceous on the front parts, and greyish and more obscure on the tegmina; head produced,

not triangular, rounded, eyes rather prominent; pronotum comparatively long ; scutellum impressed in

the middle; tegmina narrowed towards the apex; wings dark; abdomen fuscous above, underside

reddish or reddish-yellow ; legs reddish-brown, almost unicolorous, or with more or less of the tibice and

_ tarsi infuscate.

Long. 7 millim.; Jat. ad hum. 2 millim.

Hab. Guatemaua, Cerro Zunil (Champion).

This species is allied to 7. punctulata, but it is smaller, with the head longer and

differently shaped, the pronotum longer in proportion, and the tegmina covered with

small spots, whereas in 7. punctulata they are more or less distinctly lined.

27. Tettigonia granulata. (Tab. XV. fig. 27.)

Tettigonia granulata, Walk. List of Homopt. Ins., Suppl. p. 195°.

Hab. Mexico (Mus. Vind. Ces.), Atoyac in Vera Cruz, Teapa in Tabasco (H. H.

Smith) ; GuaTeMALA, Pantaleon, San Isidro, and Cerro Zunil (Champion).

This species is rather closely allied to 7. granulata, but differs in the distinct large

yellow stripes and markings.

ar. fractinota,n. (Tab. XV. fig. 29.)

Vittis longitudinalibus flavis plus minusve fractis vel abbreviatis, vel ad partem deficientibus facile distin-

guenda.

Of a bright dark crimson colour, with the front parts darker, and the usual longitudinal yellow or orange

spots abbreviated or, especially on the tegmina, broken up into short patches or spots; on the average

the size appears to be somewhat smaller.

Long. 8-9 millim.; lat. ad hum. 2-22 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guatemata, San Isidro (Champion) ;

Nicaracua, Chontales (Janson).

I should describe this as a new species but for the occurrence of distinctly inter-

mediate forms, and also of two or three specimens of undoubted 7. sta in our long

series from Teapa, which all appear to belong to one variable insect. |

A type specimen from Pantaleon and one of the variety from Teapa are figured.

29. Tettigonia pumicata, sp.n. (Tab. XVI. fig. 1.)

Elongata, postice acuminata, nitida; capite pronotoque nigris, testaceo obscure maculatis, illo breviter producto,

perobtuse rotundato, oculis prominulis, hoc convexo levissime transversim striato, basi fere recta; scutello

magno, nigro, immaculato; tegminibus rubris, levibus, apice haud hyalino; corpore subtus rubro; pedibus

rufis vel rufo-piceis.

A moderate-sized species, acuminate behind when the tegmina are folded, smooth and shining; head and

pronotum black, vertex with four testaceous spots at the base, slightly produced before the eyes, very

obtusely rounded ; head with the eyes, which are rather prominent, about as broad as the base of the

pronotum; pronotum convex, finely transversely rugose, with minute testaceous spots; scutellum

shining, immaculate ; tegmina smooth, somewhat tectiform, red, without markings, and not hyaline at

the apex; wings dark; underside of the body red, the segments of the abdomen partly black ; legs red

or pitchy-red.

Long. 10 millim.; lat. ad hum. 24 miilim.

Hab. Panama, Volcan de Chiriqui 3000 to 6000 feet (Champion).

This species somewhat resembles 7. rutilans, Walk. (nec Fabr.), but differs in the

shape of the head, the concolorous tegmina, and the testaceous markings on the base

of the vertex and on the pronotum.

30. Tettigonia guerreroensis, sp.n. (Tab. XVI. fig. 2.)

Brevis, robusta ; capite pronotoque testaceis, nigro brunneoque figuratis, illo breviter triangulari, oculis haud

brown, metopidium deep black, with testaceous markings, and a large round black spot surrounded with

testaceous just below the vertex, which appears to be constant; head short, triangular, with the eyes not

prominent; pronotum very gently sinuate above the scutellum; scutellum with two ocellate spots at the

base and testaceous behind, the colour being a little interrupted, and usually forming a sort of face;

tegmina red, clavus lighter, sometimes reddish-testaceous, the whole being scantily sprinkled with small

greyish spots, which are sometimes indistinct ; abdomen dark above, testaceous below, with part of the

upper segments red; legs testaceous, tarsi in part pitchy.

notato ; pedibus testaceis, femoribus plus minusve nigro-maculatis.

An obscure-looking species, testaceous, with darker markings, and the tegmina of a leaden-red colour, with

the veins and the space bordering on them usually darker; head produced, triangular; metopidium usually

in great part black and always with a testaceous band just before the vertex, in the centre of which is

a distinct black spot, vertex shallowly compressed at the centre and sides; pronotum with the hinder

part darker, but sometimes unicolorous testaceous, except just at the base, with four spots arranged

one of which appears to belong to this species and another to a variety of it, but

neither of them answers to Walker’s description of 7. wuniguttata.

A specimen from Chilpancingo is figured.

Comparatively short and broad, narrowed in front and behind, broadest at about the middle, in shape like a

small Aphrophora; of a light chestnut or reddish-brown colour, with the central part of the vertex,

the greater part of the disc of the pronotum, the scutellum, and three spots on each tegmen light

testaceous, the spots being sometimes very distinct and sometimes confluent and obscure; head

triangular, rather long, pointed, eyes scarcely prominent ; pronotum somewhat shining, with slight but

distinct rugose sculpture; tegmina gradually and considerably narrowed to the apex, the apex not

hyaline ; underside yellow-testaceous ; legs testaceous, sometimes suffused with brownish.

alis fumosis ; corpore subtus rufo, antice nigrescente, albido ad latera notato; pedibus rufis, tarsis piceis.

Crimson-red, with small white spots arranged regularly more or less in rows over the whole upper surface,

three on the vertex, four arranged transversely on the pronotum, and about sixteen more arranged in rows

across the tegmina being most conspicuous; apparently in fresh specimens minute white scales are dotted

over part of the surface; head broad, short, very obtusely angled, eyes prominent; pronotum narrowed

in front, with the base slightly sinuate before the scutellum, the markings on the latter somewhat

variable ; tegmina lighter subhyaline at the apex; wings smoky ; underside of the abdomen red, of the

front parts darker, marked with whitish or yellowish at the sides ; legs red, tarsi more or less pitchy.

TETTIGONIA. 251

This is a very easily recognized and pretty species; it is allied to 7. stalz, and is

quite distinct from 7. albomaculata, Dist., which is somewhat similarly coloured.

A specimen from Bugaba is figured.

41. Tettigonia testudinaria, sp.n. (Tab. XVI. fig. 13.)

Nigra, testaceo vel viridescenti-testaceo regulariter marmorata; capite lato, brevi, rotundato, haud producto,

oculis magnis prominentibus ; metopidio nigro-cincto ad medium duabus lineis instructo; pronoto capite

cum oculis distincte angustiori, levi; scutello postice testaceo; tegminibus apice hyalino, levibus ; alis

fumatis ; abdomine supra rufo, subtus rufo-flavo ; pectore cum pedibus dilute testaceis.

Smooth and shining, upperside dark, regularly marbled throughout with testaceous or greenish-testaceous,

the front markings being the most pronounced and distinct ; head very short, broad, rounded, with

prominent eyes, distinctly broader than the pronotum, which is rather short and not sinuate at the

base; scutellum testaceous behind ; tegmina hyaline at the apex, the transparent part being sometimes

obscured by the smoky wings, smooth; abdomen red above, orange beneath; chest and legs light

testaceous, the former with one or two dark markings in front; size variable.

Long. 6-8 millim.; lat. ad ham. 14-2 millim.

Hab. Panama, Bugaba, Volcan de Chiriqui, Caldera, and Pefia Blanca (Champion).

The markings of the tegmina are probably as bright in life as those on the front

part of the upper surface, but in several specimens they are faded; this appears to

be sometimes caused in the group through the action of the juices of the abdomen,

but the effect is not nearly so great on the whole as might be expected from the

delicacy of the integument, the colours being in most species retained with at all

events something of their pristine brilliancy.

A specimen from the Volcan de Chiriqui is figured.

Castaneous-brown, front parts more or less black, shining; head short, rounded, with very prominent eyes,

which project considerably beyond the sides of the pronotum ; metopidium black, with three testaceous

bands ; head with a white spot in the centre and one on each side on a depression behind the eyes, and

versely ; scutellum with a spot before the apex whitish-testaceous; tegmina gradually narrowed behind,

with about seven rounded or elongate whitish or bluish-white patches on each, of which three or four

are most conspicuous, and in mature specimens are surrounded with a ring of darker colour; abdomen

red, front part of the underside whitish-testaceous, marked more or less with fuscous; legs testaceous,

sometimes marked with darker colour, or with at least the apex of the tibiz and the tarsi infuscate.

This species varies considerably in colour and to a certain extent in the markings.

It may be known from its allies by the very short head, which is scarcely produced

before the eyes and is rounded in a very obtuse angle; the ground-colour is either

reddish, greyish-brown, or yellowish-white. There is an insect in our collection from

Mexico city which appears to be a variety of this species, but it has the head and

pronotum covered with large black spots and markings; I cannot, however, separate it

structurally.

This species differs from the preceding chiefly in having the head more conical, the

vertex flatter, and the sculpture of the pronotum less evident; the head, pronotum,

and tegmina are entirely testaceous, with the exception of a black spot on the front of

the vertex: Signoret at first treated it as a variety of the preceding, but afterwards

separated it. Iam inclined to think that 7. uniguttata is a colourless or immature

variety of the preceding species.

subtus plerumque testaceo ; pedibus testaceis ad partem piceis.

A large, brightly-coloured species, with strongly contrasted black, yellow, and orange bands, the former having

a cyaneous reflection in certain lights; head long, produced in an isosceles triangle, with the sides slightly

rounded and bluntly angled at the apex, entirely black, except for a small portion of the metopidium above

the rostrum—if viewed from the side, subexcavate, sharply pointed, and slightly deflexed ; pronotum

bright yellow, with the front part abruptly black, finely rugose ; scutellum large, black; tegmina dull,

smooth, with a black band at the base (forming with the scutellum, which it includes, a broad black band

right across the body of the insect) ; a long yellow space behind this, and a broad black band just behind

the middle, followed by a bright orange space before the apex, which is black ; underside mostly testaceous,

fuscous towards the apex of the abdomen; legs testaceous, more or less pitchy.

Long. 14-15 millim.; lat. ad hum. 33 millim.

Hab. Panama, Bugaba (Champion).

A considerable series. ‘This is one of the most gaudily coloured and conspicuous

Upperside fusco-testaceous, with black markings on the head and three light testaceous spots on the pronotum ;

head triangular, depressed, with the sides towards the front raised in a ridge on each side; tegmina

smooth and rather shining, with two large round testaceous spots at the base, four in a line just behind

the middle, the two inner ones being smaller and not rounded, and two large and conspicuous round spots

at the apex; underside and legs light testaceous.

Long. 18 millim.; lat. ad hum. 3 millim.

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

The specimen on which I have described this species appears to be somewhat

immature, and the colour is probably darker as a rule, but the eight large and

conspicuous spots on the tegmina render the insect so easily recognizable that I have

thought it best not to pass it over.

orange, and the underside light testaceous-yellow or whitish-testaceous; head more excavate and more

plainly ridged at the sides and front, with the ridging distinctly rugose, and with a fine central furrow;

tegmina smoother and more shining, with the extreme apical margin subhyaline.

Female larger, broader, and duller, with the upper surface more fuscous, the metopidium (except in front) and

the underside yellowish, except the central part of the abdomen, which is pitchy; head less excavate

I at first described these as two species, but I believe that they are sexes of one only,

as I can find no tangible point of difference between them, and they both come from

the same locality.

scarcely apparent, and in others very distinct, and some specimens are rather darker

with darker and plainer venation.

Like the preceding, this species varies somewhat in colour, the tegmina being some-

times of a dirty-white colour, with the veins and margins darker; this may be partly,

though not altogether, due to discoloration.

Very like the preceding, of which it may possibly be a variety, but easily distinguished by the base of the

head and front of the pronotum being black, as well as by the basal part of pronotum being yellow, and

the apical band on the tegmina nearly reaching the apex, and being almost divided by a triangular yellow

This species is closely allied to the preceding, but may easily be known from it by

the fascie on the tegmina, as weil as by the yellow margins of the latter, and the

testaceous head and pronotum, on the former of which there is a large dark spot

between the ocelli, and on the latter two black spots towards the apical margin.

across the upper surface, and with two bands besides—one behind the middle broader and one before

the apex narrower—red, much lighter than the basal band; legs and underside testaceous-reddish or

testaceous.

Long. 10 millim. ; lat. ad hum. 22 millim.

Hab. Panama, Bugaba (Champion).

One of our specimens has the ground-colour of the upper surface griseous; this may

be due to discoloration, but the insect looks like a distinct variety.

Tettigonia scutellata, Distant, Ent. Monthly Mag. xvi. p. 623.

Hab. Costa Rica, Rio Sucio and Volcan de Irazu 6000 to 7000 feet (Rogers 1).

This species is allied to 7. rufofasciata, but it is smaller and narrower ; the front

parts are yellow and the tegmina rose-red, and the insect may be known by the two

distinct black spots on the scutellum; there is, further, a rather large black spot on

the vertex of the head and two smaller black spots on the pronotum.

The specimen figured is from the Rio Sucio.

tegminibus maculis vel lineis quibusdam obscuris fusco-purpureis; corpore subtus pedibusque dilute

testaceis.

Purple-red ; head deep black, with the front part scarlet and the extreme apex with two black spots (which,

if viewed from the front, form the upper portion of the black frons), short, triangular, moderately

produced before the eyes, which are rather prominent; pronotum with three distinct, broad, scarlet,

longitudinal bands; scutellum large; tegmina with the margins united a little before the apex, and

a more or less elongate patch on each side of the suture obscurely fuscous-purple ; underside and legs

light testaceous.

Long. 8 millim.; lat. ad hum. vix 2 millim,

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

This is a very distinct and pretty species, which may be known at once by the three

scarlet bands on the pronotum.

We figure a specimen from Bugaba.

66. Tettigonia purpurascens, sp. n. (Tab. XVII. fig. 5.)

Elongata, parallela, purpureo-rufa, purpureo-fusco indistincte maculata; capite triangulari, ante oculos sat

prominulos producto, late longitudinaliter sulcato; pronoto convexo, lateribus antice angustatis ; tegmi-

nibus ad latera ante apicem maculis duabus parvis albidis, ad apicem ipsum hyalinis; corpore subtus

pedibusque flavo-albidis, abdominis apice rufescenti.

Of a deep purple-red colour, with obscure lines of dark purple on the head and pronotum and spots of the

same colour on the tegmina; head triangular, produced before the eyes; vertex broadly sulcate; meto-

pidium light whitish-yellow ; pronotum convex, with the sides gradually narrowed in front ; scutellum

large, somewhat raised behind; tegmina smooth, rather shiny, with two small white spots on each

before the apex touching the margins, and the apex itself hyaline, fuscous at the sides; front portion of

the underside and legs whitish-yellow.

Long. 8 millim.; lat. ad hum. 2 millim.

Hab. Guatemata, Cerro Zunil, Volcan de Atitlan (Champion).

The specimen figured is from the Volcan de Atitlan. Both localities are on the

Pacific slope.

Tettigonia costaricensis, Distant, Ent. Monthly Mag. xvi. p. 63°.

Hab. Costa Rica, Rio Sucio and Volcan de Irazu 6000 to 7000 feet (Rogers ') ;

Panama (Boucard).

This species may at once be known by its entirely black colour, with the exception

of an orange band, which, including the pronotum (except just the front portion),

encircles the whole body.

The specimen figured is from Panama.

Nigra, levis; pronoto antice, pectore et pedibus lete miniatis vel rufo-flavis; capite modice producto late

rotundato, impresso, oculis prominulis; pronoto lateribus vix antice angustatis, basi fere recta; alis

fuscatis.

Deep black, smooth, with the front part of the pronotum, except just at the apex, bright yellow-red or scarlet,

and the hinder portion abruptly black, the line of demarcation between the two colours forming an angle

in the centre; chest, except the sides, and legs bright yellow-red ; head moderately produced, transversely

impressed, broadly rounded in front, with the eyes rather prominent ; pronotum with the sides slightly

narrowed in front and the base nearly straight ; tegmina without noticeable sculpture, unicolorous black

to the apex ; wings almost as dark as the tegmina.

Long. 8 millim.; lat. ad hum. 2 millim.

Hab. Mexico, Omilteme and Xucumanatlan in Guerrero 7000 to 8000 feet

(H. H. Smith).

This insect bears a considerable resemblance to a small moth, Lithosia rubricoliis,

Superficially it is somewhat like Tettigonia costaricensis, Distant, but may easily be

known by its smaller size, differently shaped head, and red legs; in 7. costaricensis,

moreover, the pronotum is entirely yellow or reddish-yellow, except a small part of the

anterior margin. |

We figure a specimen from Xucumanatlan.

This common species appears to vary considerably in colour; and 7. proxima, Sign.,

seems to be nothing more than a variety of it. Signoret himself is doubtful on the

point (d.¢c. p. 361).

his description—24 millim. instead of 11 millim.

A specimen from David is figured.

71. Tettigonia areolata. (Tab. XVII. fig. 11.)

Signoret’s figure of this species, as of several others more or less allied to it, is very

poor and hardly recognizable; it is for this reason that we have thought it best to

give fresh ones.

The specimen figured is from Tierra Colorada.

72. Tettigonia collata, sp.n. (Tab. XVII. fig. 12.)

Quoad staturam faciemque 7. areolaie affinis; capite brevi, subtriangulari; metopidio rufo-flavo, brunneo-

Of about the size and shape of 7. areolata; head short, subtriangular ; metopidium orange, bordered with

brown ; vertex with the anterior half orange and the posterior half dark brown; pronotum light yellow,

with the anterior and posterior margins dark brown; tegmina reddish-brown, with three light yellow

patches on each, two large ones meeting behind the scutelium and not quite touching the margins, two

Of a deep velvety-black colour, unicolorous, with two common white bands—one behind the scutellum

stretching partly or nearly across the tegmina, and the other before the apex touching the suture and

margins ; there is also a spot at the margin before the apex, and a small hyaline patch before this ; some-

times the two bands are absent, and the whole upper surface is black with the exception of these one or

two small light patches ; head subtriangu!ar, obtusely rounded at the apex, but not completely rounded as

in 7. sewguttata ; legs whitish or light testaceous.

This pretty species is easily known by its coloration, the two oblong-oval patches

of the red ground-colour being enclosed by a dark border on each tegmen. Signoret’s

figure completely fails to do justice to the insect and is scarcely recognizable.

testaceous lines meeting in front, the front of the scutellum being of the same colour.

The ground-colour is brilliant crimson-scarlet, the tegmina being regularly marked

with black and crimson; but in extreme varieties the testaceous colour covers the

whole or almost the whole of the front parts, and the red colour on the tegmina is

reduced to a few small spots. It is also very variable in size, ranging from 5-8 millim.

Teapa being very constant.

The specimen figured is from Atoyac.

78. Tettigonia guttata. (Tab. XVII. fig. 18.)

Hab. Mexico} (Mus. Vind. Cws.); Hoxpuras, Ruatan I. (Gawmer); Panama (Boucard).

This species may be known by the dark central longitudinal line on the vertex, and

by the two dark more or less irregular longitudinal lines on the disc of the pronotum,

which meet or nearly meet at the base of the line on the vertex, and enclose the central

portion of the pronotum, which is red and immaculate.

We figure a specimen from Mexico belonging to the Vienna Museum.

79. Tettigonia coccinea, sp.n. (Tab. XVII. fig. 19.)

Coccinea, nigro-variegata, haud nitida ; capite sat brevi, triangulari, oculis vix prominulis; fronte immaculata ;

vertice et pronuto vitté media lat&é a medio illius ad hujus basim extensa, pronoti marginibus fuscatis ;

scutello plerumque testaceo; tegminibus coccineis, nigro sat regulariter variegatis, apice laté fusco-

hyalino ; alis fuscatis ; pectore pedibusque albidis.

Crimson-scarlet, variegated with black, dull; head small, triangular; vertex with a broad dark band starting

from the middle and continued to the base of the pronotum, the margins of the latter fuscous, the space

on either side of the dark pronotal band being more or less obscurely testaceous; frons red, without

markings; scutellum testaceous; tegmina crimson-scarlet, with rather regular black markings, the

markings being mostly zigzag and confluent, the apex rather broadly fusco-hyaline; there is a white

patch touching the costa just before the apical portion; wings dark; abdomen red; chest and legs

whitish.

Long. 9 millim.; lat. ad hum. 2 millim..

Hab. Mexico (Sallé, in Mus. Holm.), Atoyac in Vera Cruz (H. H. Sinith).

Dr. Aurivillius sent me an example of this species among some unnamed insects

from the Stockholm Museum.

Very like the preceding (7. coccinea), but with the tegmina crimson-scarlet, except the costal margin at the

apex, and with the broad central band on the front portion of the body continued from the apex of the frons

moreover, before the apical fuscous portion is absent.

Long. 10 millim. ; lat. ad hum. 2 millim.

It is possible this may prove to be a variety of the preceding, but it has a very

different appearance.

81. Tettigonia mexicana.

Tettigonia mexicana, Sign. Aun. Soc. Ent. Fr. 1855, p. 789, t. 24. fig. 7°.

Hab. Mexico (Mus. Berol.').

Among some insects sent to me from the Vienna Museum as undetermined I found

two specimens labelled ‘“ 7. mexicana, det. Signoret”; this is, evidently, however, a

mistake, as they are both red insects, one being 7. magica and the other a variety of

T. blanchardi or an allied species: the true 7. mexicana appears to be entirely yellow,

with numerous fine dark markings. I have not seen a typicalsexample and cannot

identify it in our collection.

82. Tettigonia tessellata.

Tettigonia tesseliata, Sign. Ann. Soc. Ent. Fr. 1835, p. 790, t. 24. fig. 9°.

Hab. Mexico (Mus. Berol.1); Guatemaa (Mus. Paris).

This species is not apparently represented in our collection, nor have I seen an

example. According to Signoret’s figure it has the upper surface evenly tessellated and

marked with yellow and black: in his Latin diagnosis he says: “ Rufescens, brunneo

lineolata et reticulata” ; and in the French description: “Jaune, linéolée et réticulée

de brun-rouge.”’ |

84. Tettigonia recta, sp.n. (Tab. XVII. fig. 22.)

Angusta, parallela, fusca flavo-variegata; capite obtuse triangulari, testaceo, maculis brunneis; pronoto

convexo, fusco colore dilutiori obscure variegato ; tegminibus parallelis, fuscis, maculis tribus dilute flavis ;

abdomine fusco; sterno pedibusque dilute testaceis.

A narrow, parallel species; head obtusely triangular, eyes scarcely prominent beyond the sides of the triangle,

testaceous, variegated with light fuscous; pronotum convex, dark, obscurely variegated with lighter colour ;

scutellum variegated ; tegmina parallel, fuscous, with three lemon-coloured patches on each—one at the

base, one behind the middle, and a small one at the margin between these, the apex subhyaline; abdomen

fuscous ; sternum and legs light testaceous, apex of the posterior tibise and the tarsi fuscous.

Long. 6 millim.; lat. ad hum. 14 millim.

Hab. Mexico, San Marcos (Bilimek, in Mus. Vind. Ces.), Venta de Zopilote and

Amula in Guerrero (H. H. Smith).

This species apparently belongs to the 7. venusta group.

We figure a specimen from Venta de Zopilote.

85. Tettigonia xqua, sp.n. (Tab. XVII. fig. 23.)

Fusco-brunnea, antice albido et griseo variegata, tegminibus plus minusve obscure rufo vel griseo-rufo varie-

gatis; capite producto obtuse rotundato, oculis vix prominulis ; pronoto capite paullo longiori; tegminibus -

sat parallelis ; abdomine supra fusco; corpore subtus et pedibus testaceis, plus minusve infuscatis.

Parallel, fuscous or fuscous-brown, with the head, pronotum, and scutellum variegated with lighter and darker

shades of brown, as well as with greyish and testaceous colour; head produced, obtusely rounded in front ;

pronotum a little longer than the head; tegmina scarcely narrowed to the apex, with several irregular

red or greyish-red spots on each, more or less obscure, apex subhyaline, with a little clear hyaline spot on

each tegmen near the costal margin; abdomen fuscous above ; underside and legs testaceous, more or

less infuscate.

Long. 6-7 millim, ; lat. ad hum. 13 millim.

Hab. Mexico (Boucard, in Mus. Holm.), Cuernavaca in Morelos (H. H. Smith) ;

GuaTEMALA, San Gerénimo (Champion).

This insect appears to be closely allied to 7. recta, and at first I was inclined to

regard it as a variety of that species; but the coloration is not the same and the head

is a little differently shaped. ‘The specimen from San Gerénimo may possibly belong

to another species, but I do not feel justified in separating it.

An example from Cuernavaca is figured. |

86. Tettigonia albiceps, sp.n. (Tab. XVII. fig. 24.)

Parva, fusca, fusco-rufo obscure notata; capite magno, producto, rotundato, albido, oculis prominulis ;

apicem obscure subhyalinis ; abdomine supra lete rufo; corpore subtus et pedibus albidis vel albido-

testaceis.

A small, insignificant, fuscous species, with obscure red markings ; head large, produced and rounded, about as.

long as the pronotum, whitish-testaceous, with two minute brownish spots at the base; forehead light

brown, with two testaceous spots, one above the other, in the middle surrounded by dark colour; pro-

notum comparatively short, light in front, with two reddish spots on the anterior margin, joining the

dark colour; tegmina obscurely suffused with red, especially at the claval suture; abdomen crimson

above ; underside and legs very light testaceous.

Long. 5 millim.; lat. ad hum. 1 millim.

This is an obscure little species, but it appears to be quite distinct, and may be

easily known by its large, rounded, whitish head.

In this species the head is produced and dome-shaped before the eyes (the extreme

I believe that there is some mistake with regard to this species, and give the

localities for what they are worth ; it is not represented in our collection. St&l omits

it altogether from the “ Hemiptera Mexicana” (Stett. ent. Zeit. xxv. pp. 49-86) ; it

appears to be a very distinct and pretty species.

No one would recognize this species from Signoret’s figure; he represents it with a

snow-white head and pronotum and drab tegmina, whereas it is a bluish-green insect,

with the head and usually the front part of the pronotum lighter. I was only able

to identify it by comparison with specimens kindly sent to me from the Vienna

Museum ; Signoret’s description is much more accurate than his figure.

The specimen figured is from Orizaba.

The hinder spot on the central line of the pronotum is sometimes wanting, and the

tegmina, which are described by Signoret as “ immaculées,” occasionally have a small

patch at the shoulder on a line within the outer margin fuscous.

This appears to be merely a variety of the preceding (7. lutea) with two spots (instead

of one) on the front of the vertex, and two (instead of one) towards the anterior margin

of the pronotum ; as, however, I have only seen one specimen I prefer not to unite them

at present. The species is not represented in our collection.

Yellow, with a broad central refescent line extending from the top of the forehead along the vertex (where

it is dark in front), pronotum, scutellum, and suture to the apex of the tegmina; on each side also there

is a corresponding line reaching from the metopidium along the margins of the pronotum (which are dark)

Testaceous, with the head and pronotum spotted and lined with black or fuscous, the latter with four or six

small dark spots on the front and four longitudinal lines reaching from just behind there to the base, the

base sinuate; head nearly as long as the pronotum, produced, obtusely rounded in front; scutellum yellow,

with dark markings; tegmina narrowed to the apex, with regular lines of grey, reddish-brown, and

testaceous, which are somewhat variable in tint; underside and legs orange.

Of a light testaceous or yellow colour, with a broad dark band extending from the front to the apex of the

tegmina; this band is irregular, being narrowest in front and widest before and behind the middle:

occasionally it is reduced in extent; head rather small, distinctly narrower than the pronotum, somewhat

produced before the eyes and angled, broadly rounded in front; pronotum short, broadly sinuate at the

base, with the sides rounded; tegmina smooth and rather shiny, hyaline; legs and underside light testaceous.

The species is variable, and the dark band is often partly or almost entirely wanting ;

the head also appears to vary in size. The specimen from Juarez may belong to

another species.

An example from Cerro Zunil is figured.

102. Tettigonia verecunda, sp.n. (Tab. XVIII. fig. 7.)

Fusiformis, albida, rufo-brunneo et miniato lineata; capite producto, ante oculos leviter angulato, deinde

Of a golden, testaceous, or greenish-testaceous colour, variegated with black and brown; head triangular,

pointed, eyes prominent, front of vertex with three large black spots, forehead with two black lines;

pronotum narrowed in front, longer than the head, with a short black line on the disc, sometimes wanting,

and two longer or shorter lines in the centre of the base, flanked by two spots at the angles; the markings,

however, are variable, and some are occasionally wanting ; scutellum unicolorous, except for two spots at

the base meeting the basal lines on the pronotum ; tegmina considerably narrowed to the apex, variegated

with brown, and with a broad black line at the shoulders, meeting another on the sternum; abdomen

The markings are variable in this insect: in one of the specimens from the Volcan

de Irazu the two central lines extend from the base for two-thirds of the length of the

pronotum, while in the type-form they are reduced to two patches. The tegmina

sometimes have the darker markings uniformly brown or dark fuscous, and the ground-

colour is very variable.

A specimen from Orizaba is figured.

Head and pronotum testaceous, variegated with reddish-brown ; head broadly triangular, eyes rather prominent ;

pronotum with a distinct whitish suboblique line on each side; scutellum with two black spots at the

base; tegmina dark brown, with a large whitish patch extending over a great part of their surface,

constricted and very narrowly divided in the middle, and enclosing a common fuscous oval patch at the

suture ; before the apex there is an irregular transverse whitish band ; legs testaceous.

Long. 6 millim.; lat. 2 millim.

Hab. Gouatemana, Cerro Zunil (Champion).

This species is more robust and has a broader head than.the preceding. At first

sight, as will be seen from the figures, it is extremely distinct, but 7. induta is so

variable that 7. clepsydra may prove to be only a variety of that species. The

specimen of 7. induta from the Volcan de Atitlan seems to form a connecting-

link ; it is possible, however, that the insects I have described as 7. induta ought

to be further divided.

105. Tettigonia flavivitta, sp.n. (Tab. XVIII. fig. 10.)

Brevior, brunnea, testaceo flavoque variegata; capite sat brevi, triangulari, oculis prominulis ; pronoto postice

Comparatively short and broad, widest about the middle, brown, variegated with lighter and darker colour, and

with a broad irregular yellow band on the tegmina extending from the shoulder to behind the middle ;

head short, triangular, eyes more or Jess prominent; pronotum convex, narrowed in front; scutellum

variegated with testaceous; underside more or less fuscous; legs variable in colour, usually testaceous,

A small species, striped alternately with red and testaceous lines, the outer ones almost meeting just before

the vertex close to a round black spot on the top of the forehead, and an inner pair meeting and

forming a rounded angle within those on the vertex; a central line is continued down the pronotum

and scutellum; head produced, obtusely rounded ; pronotum with the sides slightly rounded; tegmina

with the costal margin purple to beyond the middle, and with the apex broadly hyaline and more or less

distinctly marked with transverse fuscous lines; abdomen fuscous above, testaceous, or in part fuscous,

beneath ; legs testaceous.

Long. 6-7 millim.; lat. 13 millim.

Hab. Mexico, Orizaba (Bilimek, in Mus. Vind. Ces.), Chilpancingo and Xucumanatlan

This species is allied to 7. compta, but is on the average larger, with the head more

pointed and the colour different. The purple lines on the disc of the tegmina are

sometimes indistinct, but the costal margin (as in 7. compta) appears to be always

purple from the shoulders to behind the middle.

An example from Chilpancingo is figured.

This widespread and common American species appears to be very variable in size

and in the shape of the head, which is much more produced in some specimens than in

others. It is possible that some of the small examples with less produced head may

belong to different species, but intermediate forms occur, and they are not, I think,

really distinct. The reticulation of the apex of the tegmina will distinguish 7’. moldipes

from most of the allied species.

Hab. Guatemata, Totonicapam 8500 to 10,500 feet (Champion).

This is a very distinct species; it is in some points allied to 7. mollipes, but differs

by its less pointed head, dissimilar coloration, and the absence of reticulation at the

apex of the tegmina.

114. Tettigonia diducta, sp.n. (Tab. XVIII. fig. 17.)

subtus et pedibus flavo-testaceis.

A small, inconspicuous, green or greenish species, with a broadly triangular head, which is plainly, though

obtusely, angled in front; head and forehead reddish-brown, more or less distinctly variegated with

testaceous, the latter colour sometimes prevailing; pronotum light green, usually darker on the disc and

at the base, scarcely longer than the head; scutellum greenish-testaceous ; tegmina with strongly marked

light-coloured veins, reticulate towards the apex, which is rather broadly hyaline; abdomen fuscous

In the reticulation of the apex of the tegmina this species resembles small examples

of T. mollipes, from which it may be easily known by the shape and coloration of the

head, and the comparatively stronger venation of the tegmina.

A small and inconspicuous species, with the front-parts variegated more or less obscurely with light brown and

testaceous; forehead without markings, except just before the vertex, where there is a round black

shining spot; head large, rather longer than the pronotum, produced and broadly rounded in front, eyes

A very small and insignificant green species, with the head short, very obtusely angled, and the eyes moderately

prominent; forehead and head testaceous, the former with fine transverse black lines, and the latter,

together with the anterior part of the pronotum (which is testaceous or greenish-testaceous in front and

at the sides), distinctly figured with black; pronotum convex and shining; scutellum testaceous,

unicolorous or with faint traces of figuration, with two small black spots at the base; tegmina with the

suture narrowly, but usually distinctly, testaceous, apex hyaline; abdomen black above, the underside

testaceous, variegated with fuscous ; legs testaceous,

This species, though very insignificant in appearance, seems to be distinct and

constant, and is very easily known by the delicate figuration of the head and the front

of the pronotum. ‘There is a considerable series in our collection, all from Mexico.

I at first described this insect under another name, but I find that it is identical with

three specimens in the Belgium Museum labelled ‘“ Guadeloupe, Delauney,’ and named

“ T. proliaa, Lethierry, n. sp.” I do not known whether a description of the species

has been published by M. Lethierry or not, but I have adopted his name in order to

avoid confusion if such is the case.

An example from Atoyac is figured.

A rather small, shining, bright green species, easily recognizable by the rather large yellow head, which has a

well-marked irregular black band running across between the upper margin of the eyes, these being slightly

prominent; pronotum scarcely, if at all, longer than the head, lighter in front; scutellum testaceous, with

very faint traces of darker lines; tegmina lighter at the margins, especially in front, hyaline at the apex,

the extreme tips smoky; wings dark; abdomen fuscous above; underside and legs light yellow, claws

Head large, considerably produced, rounded, testaceous, with a black line encircling the vertex, and another

just inside this including a testaceous space; there are also two fine lines on the centre of the disc

proceeding from the apex of the latter to the base of the head; eyes not very prominent; pronotum

convex and shining, distinctly shorter than the head, testaceous, with the centre of the disc, and the base

narrowly, greenish ; scutellum large, with obscure dark lines; tegmina green, with two broad crimson

bands—one on the clavus, the other on the corium, the margins light ; abdomen orange above; underside

and legs yellow.

This insect may possibly be a variety of 7. guadrivittata, but it differs from the

examples which I have seen of that species in having the head less triangular, more

rounded, and figured as above described, and the pronotum comparatively shorter, as

well as in having two crimson bands only on each tegmen. In 7. quadrivittata the

head is distinctly more triangular, of a clear testaceous colour, or suffused with red,

with a broad black line along the vertex.

120. Tettigonia idonea, sp.n. (Tab. XVIII. fig. 22.)

Obscure rufo-castanea; capite plus minusve producto, obtuse rotundato-angulato, oculis prominulis, limbo

testaceo, nigro antice marginato; fronte flavo-testaceé; pronoto convexo, limbo anteriori et laterali

albido-testaceo, margine posteriori et vitté sat lata longitudinali ante marginem anteriorem interrupta

virescenti ; scutello fusco-rufo, unicolori; tegminibus apicem versus angustatis, margine exteriori anguste

testaceo, sutura pone scutellum et duabus vittis virescentibus, apice haud hyalino; corpore subtus testaceo ;

pedibus testaceis, plus minusve fusco suffusis.

A moderate-sized species, of a dark velvety reddish-chestnut-colour; head more or less produced, obtusely

rounded in front, with the eyes rather prominent; round the front and sides runs a sharply-defined

testaceous border, bounded before the testaceous forehead by a black line; pronotum convex and

shining, with the front border and sides testaceous, and the posterior margin and a longitudinal central

band, ceasing before the apical border, green ; scutellum fuscous-red ; tegmina gradually and considerably

narrowed to the apex, with the exterior margin testaceous, and a line surrounding the scutellum and

continued along the suture to about the middle, and two other lines (one extending along the claval

TETTIGONIA. 277

suture, and the other parallel to it on the disc of the corium), green, the apex not hyaline; underside

light testaceous ; legs testaceous, in part fuscous.

_ Long. 9 millim.; lat. 2 millim.

_ Hab. Guatema.a, Cerro Zunil (Champion).

This is a very distinct species; at first sight it has a dark and obscure appearance,

but viewed under a lens the coloration is very striking.

_ There is a very large series of this species in our collection. It may at once be known

by the black stripes on the green ground of the tegmina, and the large and conspicuous

black spot in the centre of the vertex of the head. |

Var. delineata,n. (Tab. XVIII. fig. 23.)

Major, tegminibus rufo-brunneis vel brunneis, vittis ceeruleis multo magis conspicuis, facile distinguenda.

Rather larger than the type-form, with the general ground-colour darker, and the elytra of a rich reddish-

brown or brown colour, with very conspicuous light blue or greyish-blue stripes; the head is a little more

pointed in front, but in this character the type-form varies considerably.

Long. 7-8 millim.; lat. 2 millim.

Hab. Mexico, Cuernavaca in Morelos, Chilpancingo and Amula in Guerrero (H. ZH.

At first sight the variety looks distinct, but on a close comparison it will be seen that

it can hardly be separated, and one or two of the specimens from Teapa are entirely

intermediate.

We figure a specimen of the variety from Cerro Zunil.

122. Tettigonia composita, sp.n. (Tab. XVIII. fig. 24.)

Sat robusta, nitida, apicem versus acuminata, nigro, castaneo, testaceo et interdum rufo plus minusve distincte

tibus; abdomine supra rufo, subtus fusco; sterno pedibusque testaceis.

Rather shiny, narrowed towards the apex ; head short, triangular, with the vertex plainly angled, variegated

with testaceous and rufous-brown, and with dark markings in front, eyes a little prominent; pronotum

convex, narrowed in front, with dark lines bordered by testaceous and rufous-brown longitudinal bands ;

scutellum similarly coloured to the pronotum ; tegmina dark red or castaneous-red, with the margins and

curved light bands; abdomen orange-red above, fuscous below; sternum and legs testaceous, more or

less infuscate.

Long. 8 millim.; lat. 2 millim.

Hab. Mexico, Orizaba (Bilimek, in Mus. Vind. Ces.) ; GUATEMALA, Cerro Zunil

(Champion).

A variable species: in the specimen taken as the type the ground-colour of the

tegmina is strongly marked with reddish tints, but these are absent in other examples,

perhaps due to their being somewhat immature. It is almost impossible to describe

the coloration accurately.

128. Tettigonia flaccida, sp. n.

7. composite affinis, sed angustior; capite longiori, oculis minus prominulis, et colore brunneo viridi-testaceo

sat regulariter lineato distinguenda.

Allied to the preceding species, but narrower and more parallel, with a longer and comparatively narrower

head and the eyes less prominent; head, pronotum, and scutellum light brown, lined with greenish-

testaceous, the central line commencing at the base of the vertex, gradually dividing on the pronotum

and scutellum, and enclosing a dark line; pronotum scarcely longer than the head; tegmina with rather

regular greenish-testaceous lines ; underside more or less fuscous; legs testaceous, with the knees and

. tarsi darker.

Long. 8 millim.; lat. 14 millim.

Hab. Mexico, Orizaba (Sallé; coll. Signoret, in Mus. Vind. Ces.).

I have found examples of both this and the preceding species among unnamed

material belonging to the Vienna Museum.

Hab. Mexico (Mus. Holm.'), Amula and Venta de Zopilote in Guerrero, Cuernavaca

in Morelos (H. H. Smith), Vera Cruz (Mus. Holm.); Guatema.a, Cerro Zunil (Champion).

This is rather a large species, with a strongly produced triangular head and not very

prominent eyes; the head and scutellum are variegated in a constant pattern, but the

light front of the pronotum is almost unicolorous; the tegmina are olive, with a deep

brown tinge, the wings are brownish, and the abdomen orange.

A specimen from Cuernavaca is figured.

125. Tettigonia obtusior, sp. n. (Tab. XVIII. fig. 26.)

Praecedenti affinis, sed capite multo breviori et obtusiori, colore magis viridi et parte anteriori dilutaé pronoti

Allied to the preceding (7’. urbana), but easily distinguished by its much shorter and more obtuse head and the

greener colour, and also by having the front portion of the pronotum distinctly variegated.

Long. 9-10 millim.; lat. 2-23 millim. .

Hab. Panama, Volcan de Chiriqui (Champion).

TETTIGONIA. 279

It is possible that this insect may be a variety of the preceding, but as it comes from

an entirely different locality I am inclined to regard it as distinct.

Tettigonia limbaticollis, Stal; Stett. ent. Zeit. xxv. p. 75 (1864) *.

Hab. Mzxico (coll. Signoret}), Teapa in Tabasco (H. H. Smith).

This species is allied to 7. urbana, from which it may be known by the greener

colour, the more distinct figuration of the front-border of the pronotum, and the narrow

black line bounding the yellow margins of the latter; from 7. obtusior it may be

separated by the more elongate head, as well as by the presence of the black lateral

line on the pronotum, which appears to be a constant character, and to be wanting

in the allied forms.

127. Tettigonia anceps, sp.n. (Tab. XVIII. fig. 28.)

Precedentibus affinis, viridis vel olivaceo-viridis ; capite elongato, triangulari, testaceo nigro-lineato ; fronte

testaceo, unicolori ; tegminibus apicem versus angustatis, suturaé anguste flava; abdomine supra rufo ad

partem infuscato; corpore subtus pedibusque testaceis.

Allied to the three preceding species, from which it may easily be known by the unicolorous scutellum and

the less close variegation of the head; it is further distinguished from 7’. limbaticollis by the absence of

the black lateral line on the pronotum, and from 7. obtusior by the much more elongate head.

Long. 7-9 millim.; lat. vix 2 millim.

Hab. Panama, Bugaba (Champion).

A considerable and very constant series has been received. It is possible that this

and the three preceding insects may by future writers be regarded as belonging to

one variable species, but at present it seems better to separate them.

Signoret ? describes this species as yellow, with black lines, whereas in nearly every

example contained in our large series the colour of the upper surface is for the most

part dark green, with the head, the front of the pronotum, and the scutellum yellow.

Some of our light-coloured examples, however, nearly agree with his figure.

As there is some doubt about the identification of 7. occatoria, a description of our

insect is added :—

280 HEM1PTERA-HOMOPTERA.

Green, occasionally greenish-testaceous ; head testaceous-yellow, somewhat produced and rounded, with two

black lines nearly or quite meeting in front, two inside these meeting in an acute angle, and a central

line at the base, often only indicated ; all these lines extend on to the pronotum (which is testaceous in

front, and has a small black line also at the margin), and the central three are continued on the testaceous

scutellum ; on each of the tegmina there are six or seven black lines, which are much more apparent on

the lighter specimens; apex of the tegmina hyaline, with the extreme tip and a band before this fuscous ;

abdomen above black ; underside and legs clear testaceous-yellow, the apex of the tibie and claws being

sometimes fuscous.

Long. 5-6 millim.; lat. 14 millim.

We figure a specimen from Bugaba.

129. Tettigonia sexlineata. (Tab. XVIII. fig. 30.)

_ than in our other examples. .

We figure a specimen from Teapa.

Hab, Mexico (coll. Germar & coll. Spinola?+).—Brazit, Rio Janeiro, Santa Teresa

(Mus. Roy. Belq.).

I cannot identify this species in our collection, although there are several which are

apparently very near it, to judge from Signoret’s figure.

131. Tettigonia carissima, sp.n. (Tab. XIX. fig. 1.)

Parva, virescenti-flava, nigro longitudinaliter vittata; capite sat lato, rotundato, oculis vix prominulis;

fronte nigra; pronoto antice vix angustato; scutello magno; tegminibus ad apicem intus fumatis,

iridescentibus ; alis fuscis ; abdomine fusco; pedibus albidis. *

A very small species, greenish-yellow, with the metopidium black ; on the upper surface two black stripes meet

in the middle of the vertex, and are continued on each side nearly to the apex of the clavus, where they

end in a point; between these markings there is a dark line extending along the centre of the pronotum

and the scutellum; the sides of the tegmina are black, variegated with a few yellow stripes and patches,

the yellow colour being continued to the apex, the inside apical portion being smoky and iridescent ;

wings and abdomen infuscate ; legs slender, whitish.

Long. 43-5 millim.; lat. ad hum. 1 millim.

Hab. Panama, Bugaba (Champion).

This very pretty little species appears to be considerably smaller than 7. sagata;

the head, too, is more rounded, and has the two longitudinal black stripes meeting in

TETTIGONIA. 281

the centre of the vertex (instead of being continued to the apex), there is a dark central

stripe on the pronotum and scutellum (which is wanting in 7. sagata), and the coloration

of the sides of the tegmina is different.

132. Tettigonia anita, sp.n. (Tab. XIX. fig. 2.)

Robusta, nigra, flavo vel viridescenti-flavo longitudinaliter vittata; capite rotundato; fronte nigra ;

tegminibus postice maculis quibusdam rubescentibus vel flavis vel rufo-flavis instructis; alis fuscatis ;

abdomine lete rufescente ; pedibus dilute flavis.

Comparatively a stout species, black, with a semicircular yellow band on the vertex, and a small similarly-

coloured spot, sometimes absent, at the base of the head, from which is continued a yellow band to

the apex of the scutellum, and narrowly along the suture to the apex of the clavus, where it is joined

by two lateral yellow or greenish or bluish bands proceeding from each end of the semicircular band on

the vertex; the sides of the tegmina are black, with pink, crimson, or orange spots or patches towards

the apex ; wings dark ; abdomen bright red, pygofer testaceous or fuscous ; underside of front-parts and

legs clear light yellow.

Long. 6—7 millim.; lat. ad hum. vix 2 millim.

Hab. Panama, Bugaba (Champion).

133. Tettigonia lativittata, sp.n. (Tab. XIX. fig. 3.)

lateralibus ab apice verticis ad apicem clavi continuatis, aliisque ad latera tegminum, nigris; alis

fuscatis ; corpore subtus pedibusque flavis.

A small species, varying considerably in size, with the ground-colour yellow or greenish-yellow, the hindmost

stripe being usually bluish, and with a very clear and broad black stripe continued from the apex of the

vertex to the apex of the clavus, where it is joined by two other stripes which commence in front of

the head before the eyes; head triangular, produced, eyes scarcely prominent; the sides of the tegmina

are striped with yellow, blue, and black, and the apical portion is fuscous, in part clear hyaline, with one

or two yellow or blue spots or bands ; underside and legs light yellow.

Long. 5-64 millim.; lat. ad hum. 1-13 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith); Nicaraaua, Chontales (Janson) ;

Panama, Bugaba (Champion).

Our collection contains a considerable series of this insect, which appears to be allied

to T. obtecta, Sign., from Peru. In this and the three following species the striped

pattern is continued over the whole surface from the vertex to the hinder portion, and

the ground-colour is more or less evenly divided, so that it may be equally reasonable

to describe them as black with yellow stripes, or yellow with black stripes.

A specimen from Bugaba is figured.

134. Tettigonia salutaris, sp.n. (Tab. XIX. fig. 4.)

Nigra, miniato-virgata; capite sat magno, ante oculos prominulos modice producto rotundato; fronte dilute

abbreviated, a broad band at the claval suture, and another crescent-shaped band before the apex, bright

scarlet; the head is usually scarlet, with two spots in front and a large semicircular patch before the

base ; head produced, rounded; pronotum very gently narrowed towards the front; scutellum marked

with red; margin of the tegmina broadly testaceous ; forehead, underside, and legs light testaceous-

yellow.

Long. 8-9 millim.; lat. 14-2 millim.

Hab. Panama, Bugaba (Champion).

There is a variety of this insect in which the black markings of the head resolve

themselves into two irregular longitudinal bands which are continued on the pronotum,

and the two spots on the front of the vertex are confluent. This species is very distinct

and strikingly coloured. Numerous examples were obtained.

135. Tettigonia infulata, sp.n. (Tab. XIX. fig. 5.)

Rufa, albido, flavo nigroque variegata; capite triangulari, ante oculos producto ad verticem obtuse angulato ;

tegminibus variegatis ; abdomine rufo, sterno testaceo; pedibus testaceis, ad partem fuscatis.

Front-parts yellowish-red ; head forming an equilateral triangle, with a black spot at the vertex, which is

confluent with two black bands, these being continued on to the pronotum, which has two other black

bands, one on each side, the two central ones being continued on the scutellum; tegmina red, variegated

with dashes of black and white, and with a yellowish band just before the fuscous inner margin, the apex

fuscous, variegated with hyaline; abdomen red; underside of front-parts testaceous ; legs testaceous, in

part fuscous.

Elongata, subelliptica, ad medium latior, pallide testacea vel flava; capite ante oculos angulato, modice

producto, oculis prominentibus ; pronoto convexo, capite distincte latiori, maculé und ad medium magna,

subrotundata ; scutello ad partem fusco; tegminibus ad basim et ante apicem plus minusve nigris, sutura

rufa vel fused, maculis utrinque ad medium denticulatis suturam attingentibus, duabusque aliis pone

medium spe cum nigro colore apicis plus minusve confluentibus instructis ; pedibus flavis, unguibus

fuscatis.

Broadest about the middle, of a pale testaceous colour, sometimes reddish-yellow ; head with the sides inside

the eyes (which are large and prominent) straight or nearly straight, produced a little before the eyes

and then angled, the anterior part broadly rounded; pronotum broader than the head, convex, with a large

rounded dark spot on the centre of the disc; tegmina with the suture fuscous or reddish, with a broad

dark band at the base not reaching the shoulders, and more or less of the space before the apex dark ; at

the middle on each side, touching the suture, is a denticulate dark spot, and behind these there are two

more spots reaching the suture, the latter in some specimens forming a mere thickening of the apical

coloration, and in others quite distinct ; legs yellow, claws fuscous.

Long. 8-10 millim. ; lat. 2-3 millim.

apice rufescenti; tegminibus ad apicem valde angustatis ; pedibus dilute flavis.

TETTIGONIA. 283.

Pale testaceous, with the base and sides of the pronotum, a broad band on the tegmina, and sometimes the

apical portion of the scutellum, red, the red band on the tegmina occasionally covering the whole of the

corium except the apex; head short, but longer than the pronotum, which is very short, scarcely produced

before the eyes and broadly subtruncate, eyes prominent; tegmina much narrowed towards the apex; legs

light testaceous-yellow.

Long. 7-8 millim.; lat. 2-22 millim.

rufis, apice subhyalino ; alis tuscis; sterno pedibusque testaceis, abdomine subtus rufescenti.

Rather robust and shining, of an olive-green colour, with the greater part of the head, the front parts of the

pronotum, the whole scutellum, and the shoulders and a moderately broad line reaching along the claval

suture, bright golden-orange-red ; the forehead is lined transversely with black, and variegated with

black and testaceous ; head triangular, produced, rather sharply angled at the vertex, distinctly narrower

than the base of the pronotum ; pronotum convex, narrowed in front, the base broadly sinuate before

the scutellum ; tegmina considerably narrowed towards the apex, the latter more or less subhyaline ;

wings dark ; chest and legs testaceous, abdomen orange-red.

corpore subtus dilute flavo ; pedibus testaceis, apice tibiarum et unguibus nigris.

A moderate-sized species ; the head rather short, triangular, obtusely rounded in front, yellow, with three large

orange spots—two near the eyes, which are a little prominent, and one in front; forehead lined trans-

versely with black, with a clear space in the centre and a large round black spot surrounded with a clear

space before the vertex; pronotum convex, olivaceous, with the front and sides broadly yellow, and an

orange spot on each side of the front part of the olivaceous colouring; scutellum orange, unicolorous,

Smaller and Jess robust than 7’. aurolineata, with the head more pointed, yellow or orange, concolorous, or at

most with one or two minute black markings; pronotum yellow or orange in front, olivaceous behind,

sometimes almost unicolorous orange ; scutellum unicolorous, of the same colour as the head; tegmina

with the suture and margins very narrowly, and the claval suture rather broadly, yellow or orange ;

abdomen orange above ; legs and underside light testaceous.

Long. 6-7 millim.; lat. 13 millim.

Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith); Guatemata, Cerro

Tettigonia rufimargo, Walk. List of Homopt. Ins., Suppl. p. 197’.

Hab. Mexico, Ciudad in Durango (Forrer), Chilpancingo, Amula, and Xucumanatlan

in Guerrero, Cuernavaca, Vera Cruz, Atoyac, Teapa, Frontera (H. H. Smith), Orizaba

(Sallé, H. H. Smith, & F. D. Godman); Guatemata, San Juan in Vera Paz (Champion) ;

Nicaraeua, Chontales (Janson); Panama, Bugaba (Champion).

Six out of the eight specimens from Chilpancingo and the single example from

Xucumanatlan are broader and more robust than the others, and also darker and more

strongly marked; they form a rather distinct variety.

Walker! gave this insect the name rujfimargo because in his type-specimen the

abdomen was dark, with red margins; this, however, is a very variable character, and

I am inclined to think that the males often have the upper surface of the abdomen

dark, whereas in the females it isred. The abdomen is entirely covered by the tegmina

while at rest, so that the name appears at first sight to have been assigned to the insect

for no reason at all. |

Var. propor, n. (Tab. XIX. fig. 12.)

Capite et plerumque scutello regulariter nigro-lineatis facile distinguenda.

Differs from the type-form in having the head and pronotum regularly lined with black, and the head a little

more produced.

Hab. Panama, Bugaba (Champion).

As a rule, the coloration of the head in 7. rufimargo is very constant, being testaceous-

yellow, with a little green or bluish patch above the ocelli, from each of which starts a

line of the same colour, these lines nearly meeting behind a small black spot on the

top of the forehead.

TETTIGONIA. 285

We figure a specimen of the ordinary form from Teapa and one of the var. propior

from Bugaba.

L. rufimargo affinis, sed capite longiori, minus obtuso, unicolori viridi-testaceo, oculis minoribus et minus

prominulis, et fronte et sterno nigris concoloribus, distinguenda.

Allied to 7. rufimargo, but differing from it in having the head rather longer and more pointed, and of a

unicolorous testaceous colour, the eyes sinaller and less prominent, and the forehead and all the front

parts of the underside deep black; abdomen crimson above, light testaceous beneath ; legs testaceous.

Long. 5 millim.; lat. 1 millim.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith).

It is possible that this insect may be another variety of 7. rufimargo, but it appears

to be quite distinct.

143. Tettigonia miniaticeps, sp.n. (Tab. XIX. fig. 14.)

Head scarlet or orange-scarlet, with a large dark spot on the disc of the vertex and a smaller one in front of

this, rather large, rounded (not triangular), eyes prominent, ocelli with a narrow black rim; pronotum

with an orange band at the margin, a greenish one behind this, and the basal part dark steel-colour ;

scutellum unicolorous orange-scarlet ; tegmina steel-blue, with the margins in front narrowly and a few

obscure markings near the shoulders more or less greenish or testaceous, these latter, however, are often

very indistinct ; abdomen above crimson ; legs and underside orange-scarlet or orange.

Long. 6-7 millim. ; lat. vix 2 millim.

Hab. Mexico, Orizaba (F. D- Godman & H. H. Sinith), Vera Cruz, Atoyac, Teapa,

Frontera (H. H. Smith); Guatemata, Coatepeque, Cerro Zunil, Las Mercedes (Cham-

This is a very distinct and handsome species. ‘There is a large series of it in our

collection, consisting of upwards of 150 examples, and it seems to be widely distributed,

but I cannot find that it has ever been described before.

A specimen from Teapa is figured.

with black; extreme margins of the tegmina towards the apex black; abdomen crimson above; underside

and legs testaceous, in part infuscate.

Long. 7 millim.; lat. 2 millim.

Hab. CENTRAL AMERICA.

There is a single example of this insect in our collection, and unfortunately it is one

of the very few specimens from which the locality-label is missing; it is, however, so

very distinct and conspicuous a species that I have no hesitation in describing it, as no

mistake could possibly arise regarding it.

Olivaceous, with a broad red border reaching round the front of the head and continued to within a short distance

of the apex, where it is interrupted by a black band, behind which the apical portion of the tegmina is

broadly orange-red, the apex itself being black ; head broad, rounded and not angular, testaceous behind

the red border and regularly figured with black ; the front of the pronotum and the scutellum are also

testaceous and regularly figured; abdomen red above; underside and legs testaceous, the latter being

very pale.

Hab. Mexico, Teapa in Tabasco (H. H. Smith).

In shape this insect is very like 7. rufoapicata, but it differs very much in coloration,

and is evidently distinct. The two species come from widely separated localities.

A small and rather narrow species, very brilliantly coloured, olivaceous, with a broad border round the vertex,

the sides of the pronotum, the scutellum (which is comparatively small), and the claval suture, bright

scarlet-orange, this colour extending along the suture from the apex of the clavus to the apex of the

light testaceous, without any spot ; pronotum almost as long as the head, very finely rugose transversely,

with the base nearly straight; scutellum rather large ; each tegmen with four white waxy-looking spots—

two on the costal margin and two on the interior margin, the front ones of the latter being semicircular

hyaline patch ; abdomen black above ; underside and legs pale whitish-testaceous, clavus and sometimes

part of the tarsi a little infuscate.

Long. 4 millim.; lat. 1 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith).

This species is allied to 7. guadriplagiata, Walk., from the “ West Coast of America,”

but that insect has a red abdomen and different markings. ‘Teapa, it may be noted, is

on the Atlantic slope.

distance on each side of the front of the vertex ; vertex with a central space light, bounded by a narrow

black line on each side, and with a narrow black line in the centre ; pronotum scarcely longer than the

head, almost parallel-sided, with two broad longitudinal rufous-brown bands in the middle and two narrow

dark fuscous bands outside; scutellum with one dark line; tegmina subvitreous, yet with very distinct

Allied to 7’. mollicula, but on the average slightly larger, with a considerably shorter head and less prominent

eyes ; on the vertex there are three small black spots arranged transversely, and the lines on the fore-

head are much less marked and sometimes almost absent, and are not continued on the vertex; on the

pronotum, which is shorter, are two rather broad transverse reddish-brown bands, the colour being usually

faint ; scutellum without the distinct central dark line; tegmina less clearly lined; abdomen yellow or

whitish-yellow.

lineisque rarioribus tegminum facile distinguenda.

Allied to 7’. mollicella, but with the head a little larger and more produced, without the black spot just before

the vertex, and with a broad, brown, transverse band between the eyes; there is another broad brown

band like this across the pronotum and two others in front of the pronotum and scutellum, as well as a

narrower one towards the apex of the latter; two or three narrow brown lines extend across the upper

part of the forehead; the tegmina are furnished with a few broader dark lines, especially towards

the apex.

Long. 6 millim.; lat. 1 millim.

Hab. Mexico, Atoyac in Vera Cruz (Schumann).

The two preceding species are each represented by four specimens in our collection,

but there is only one example of 7. tenera; it is, however, so easily recognized by

the banded appearance of the front parts of the body that I have thought it best to

describe it.

yellow line before and behind the ocelli; the pronotum narrowly yellow in front and behind, and with a

black line before the yellow base; the scutellum yellow, sometimes with a black patch at the base, and

the tegmina unicolorous, without lines, the apex being subhyaline with a small fuscous spot at the tip;

head very short, broad, rounded, eyes prominent; pronotum slightly broader at the base than the head

One of the specimens from the Volcan de Chiriqui has the upper surface black, with

the exception of a common oval yellowish-white patch behind the scutellum and two

or three light markings on the margins of the tegmina before the apex; it cannot,

however, be regarded as more than a variety.

We figure examples from Teapa and Bugaba.

Allied to 7. variegata, but at once distinguished by the very long head, which is nearly as long as the pronotum

and scutellum together, and is broadly impressed and finely keeled longitudinally in the centre; eyes

scarcely prominent ; upper surface shining black, smooth, with a common yellowish-white oval patch on

the tegmina just behind the scutellum, and three large white denticulate patches at the margins of the

sides; legs light testaceous.

This is a very small species, 5 millim. in length, somewhat closely allied to T. variegata,

but with a shorter and more rounded head and different markings. It is not repre-

Minor, paullo angustior, nigro-fusca, immaculata ; capite paullo magis producto.

Smaller and narrower than the type-form ; upper surface unicolorous fuscous-black, with at most one or two

very faint testaceous lines on the head ; head a little more sharply produced.

Long. 43 millim.; lat. 1 millim.

Hab. Mexico, Amula in Guerrero, Cuernavaca in Morelos, Teapa in Tabasco

(H. H. Smith).

T. angustula has not the appearance of a true Tettigonia, though it is closely allied

to T. variegata and T. nasuta: these three, together with 7. subflava, Sign. (from

Venezuela), might perhaps with advantage be placed in a separate genus (vide Signoret,

Ann. Soc. Ent. Fr. 1854, p. 725); but, considering the numerous transitional species in

Tettigonia, it is better to retain them in it for the present.

The variety may prove to be distinct. We figure a specimen of the type-form from

milteme and one of the var. ¢mmaculata trom Amula.

I have already alluded (anted, pp. 207, 235) to the impossibility of making any

satisfactory subdivision of this very large genus: Signoret has gone further than I have

done, and includes under it the species which are regarded above as belonging to the

genera Diestostemma, Aulacizes, Oncometopia, &c.; Stal (Kongl. Svensk. Vet.-Ak.

Handl. Band 8, no. 1, p. 70) attempts to tabulate twenty-seven species only of the

genus Tettigonia proper, and in dealing with this small number has to fall back on

differences in colour and other slight and comparative characters, which are quite

useless for the purposes of determination.

EPICLINES. 293

Fam. GYPONIDA.

This family is rather closely allied to the Tettigoniide, but differs chiefly in the

general facies, which is broader and more robust, and more or less oval or oblong-oval ;

the ocelli are situated upon the vertex, in most cases considerably behind the front

margin. It includes the genera Epiclines, Scaris, Gypona, Zinneca, and Stragania ;

Ledra, however, with its very peculiar and distinct facies, seems best placed in a

separate family. The name Gyponide is here adopted rather than that of Scaride, as

Gypona is by far the largest and most important genus; in fact, Stal (Bidrag till Rio

Janeiro-Traktens Hem.-Fauna, ll. p. 49) regards Scaris, Leth. & Serv., as merely a

subgenus of the latter.

The males are apparently much scarcer than the females, and are unknown in the

case of a large number of the hitherto described species. The characters of the last

abdominal ventral segment of the female are very important, and are often of the

greatest help towards the identification of species: in the male this segment, as a rule,

presents very little variation of any importance.

The collection before me includes one species of Epiclines and a large number of

Gypona, and Stal has described two species of Stragania from Mexico. Some of the

forms here placed at the end of the genus Gypona approach very near to Scaris, but

cannot be properly referred to it. In the insects belonging to Scaris proper the front

part of the head appears to be rounded, if viewed from the side, and the division

between the vertex and frons is quite effaced, and the ocelli are situated quite close

to the eyes. The genus Zinneca, Amyot & Serv., seems to be confined to North

America.

Some authors regard the Tettigoniide and Gyponide, as well as the Membracide,

as subfamilies of the Jasside.

EPICLINES.

Epiclines, Amyot & Serville, Hist. Nat. des Ins. Hém. p. 577 (1843).

Ledra (ex parte), Fabricius, Syst. Rhyng. p. 24 (1803).

This genus may be easily recognized by the very small triangular head, which is

produced into a short beak, and by the broad and projecting posterior angles of the

pronotum extending far beyond the base of the tegmina; the latter are strongly

narrowed behind, if viewed from above, and the head and pronotum together form a

broad triangle, so that the insect is kite-shaped. The species known appear to be all

GYPONA.

Gypona, Germar, Mag. Ent. iv. p. 73 (1821) ; Burm. Handb. d. Ent. i. 1, p.114; Amyot & Serville,

Hist. Nat. des Ins. Hém. p. 579.

This genus includes a large number of species which, for the most part, bear a very

strong resemblance one to another; the majority of them are very sombre-coloured

insects, and possess none of the bright colours and patterns which are so conspicuous

in many of the Tettigoniw. The chief authorities on the genus Gypona are Stal and

Spéngberg. The latter has described and noticed just one hundred species in the

‘Bidrag till Kongliga Svenska Vet.-Akad. Handlingar, Band v. No. 3 (1878), and has

endeavoured to arrange them into groups, but without much practical success. Apart,

however, from the divisions, which are, of course, a help to a certain extent, Spangberg’s

work is most valuable. Stal roughly grouped the species on the shape of the head—

whether produced or obtuse, if viewed from the side: in the typical Gypone@ it is

depressed above and below, and if viewed from the side projects in a sort of straight

beak, the frons being in almost the same horizontal plane as the vertex; in the extreme

forms, however, it is quite blunt and rounded, and in shape closely resembles that of

the species of the genus Scaris. The ocelli are very variable, both in size and position,

and afford useful characters; as a rule, they are situated on or about the centre of the

vertex, at a greater or less distance from one another, and only in one or two cases do

they touch the front margin; in Gypona they never appear to be placed quite close to

the eye, as in Scaris.

A rough table is added as a help towards distinguishing the species :—

* This species is very variable in colour: in some specimens the veins of the tegmina are dark and the

abdomen is black above ; in others the veins are scarcely marked and the abdomen is red. The black markings

of the pronotum, however, will at once distinguish it.

Gypona germari, Stal, Stett. ent. Zeit. xxv. p. 84°.

Hab. Mexico, Ciudad in Durango 8100 feet, and Presidio (forrer), Omilteme,

Xucumanatlan, and Chilpancingo in Guerrero, 4600 to 8000 feet, Cuernavaca in Morelos,

Atoyac in Vera Cruz, Teapa in Tabasco (H. H. Smith), Vera Cruz (Mus. Holm. 1),

(Trujillo); GuaTEMALA, near the city and Capetillo (Champion); Nicaragua, Chontales

(Janson); Panama, Volcan de Chiriqui (Champion).

In the male of this species the last ventral segment is scarcely longer than the

penultimate, subtruncate at the apex. In the female, which was apparently unknown

to Stal and Spangberg, the last segment is emarginate in a larger or smaller arc. Stal

says, “ vittis pluribus verticis thoracisque necnon venis tegminum pallide flavescentibus”;

but this character appears to be fugitive on the head and pronotum, owing to the

fading of the colour of the insect after death; the veins of the tegmina are, however,

usually distinctly marked by greenish or pale yellow lines.

There are three or four obscure, doubtful, or faded insects in our collection near

G. germari which may very probably belong to new species, but they cannot be

satisfactorily described from the examples before me. The specimen figured is from

Cuernavaca.

* Gypona decorata can hardly be said to have the interstices of the tegmina irrorated, but there are a

number of smaller and larger markings upon them, and the insect cannot well be classed with the next

section,

This insect is closely allied to G. germari, but may be distinguished by the two

minute but distinct black spots on the pronotum, and by the last ventral segment of

the female being a little longer than the penultimate, feebly sinuate at the tip, and with

a very slight subemarginate lobe in the centre. In the male the last ventral segment

is about as long as the penultimate, and subtruncate at the apex. The specimen

figured is from Chilpancingo.

Hab. Nortu America, Colorado (Mus. Vind. Ces.).—MeExico!, Teapa in Tabasco

This appears to be a very obscure species. I have seen two specimens belonging to

the Vienna Museum labelled “G. wnicolor”: one, from Colorado, presented by

Spangberg; the other, which apparently ought to be referred to G. germari, from

Mexico, and presented by Signoret. I have doubtfully identified two insects in our

collection as small examples of G. unicolor, which appears chiefly to differ from

G. germari in the subtruncate or only slightly sinuate last segment of the abdomen in

the female, and in the absence of pale bands on the head and pronotum; but these

latter are often untraceable in dead and faded specimens of G. germari.

Of about the same length as G. chiriquensis, but narrower and more parallel-sided; head shorter and broader,

with the eyes considerably more prominent; ocelli closely approximate; pronotum nearly twice as long

as the head, with distinct transverse striation ; scutellum finely asperate ; tegmina not reticulate, with the

veins green; underside and legs testaceous; the general colour is probably a bright light green in life,

Of a dark testaceous or greenish-testaceous colour in life; the tegmina with the veins (in fresher specimens)

marked with thickly-set, minute, obscure, green spots (in life the tegmina are probably in great part

green, and most likely the front parts also, but the colour apparently soon fades to a uniform testaceous

tint), and also with a small common dark spot before the apex; the abdomen darker above and light

below. The species somewhat resembles G. pallidovirens, but may be easily known by the less produced,

shorter, and more rounded head and less approximate ocelli, as well as by the female characters.

Male unknown. Female with the last ventral segment very slightly sinuate, broadly and shallowly emarginate

This insect may be known by the bright red upper surface of the abdomen, the

infuscate wings, and the deep and narrow triangular emargination of the last ventral

segment of the female. The apex of the tegmina is often broadly infuscate, a character

chiefly seen in the male sex, but occasionally present in the female. In the male the

last ventral segment is about half as long again as the penultimate, and subtruncate at

the apex. I have compared our specimens with the type of G. fervens, Walk., and

believe that the synonymy above given is correct; but the latter insect is imperfect

and without the abdomen, and, under the circumstances, it seems best to use Stal’s

name instead of Walker’s, which, of course, would otherwise have priority. The

insect figured is from Atoyac.

Closely allied to G. signoreti, but differing in its slightly shorter and broader head,

and in the female characters (which, however, are less marked in the Caldera specimen) ;

in G. signoreti the last ventral segment is deeply and sharply emarginate in the middle

in this sex, A specimen from Bugaba is figured.

and sometimes orange-red; and lighter or darker colour prevails on the front part.

All the examples examined are males, and Spangberg mentions the female of his

G. mexicana as being unknown to him. We figure a variety from Amula.

The above synonymy appears to be correct. Walker’s localities are not always to

be depended on, and it is quite possible that the type of G. vulnerata may have come

from Mexico.

This is a very distinct insect, rather broad, slightly wider behind than in front, with

the tegmina greenish (but soon fading to brown in old specimens), and rather broadly

ferruginous at the base around the scutellum. In the female the last ventral segment

is deeply excised in the middle, and the apex of the excision is sharply emarginate

and furnished with a small fold on each side, the side-lobes of the segment being

broad and considerably produced. The insect figured is from Atoyac.

There are three males of this species in our collection. The colour is apparently

very variable: the head, pronotum, and scutellum are entirely testaceous, with the

ridge separating the vertex and metopidium dark; or entirely fuscous-black, with or

without obscure lighter markings, and the apex of the scutellum only testaceous.

The tegmina are hyaline, with strongly marked and coarsely reticulate dark veins,

which are thicker at the base, and in lighter specimens present the appearance of a

darker band round the scutellum. A specimen from Bugaba is figured.

Hab. Muxico 1 (Sallé), Atoyac in Vera Cruz, Teapa in Tabasco (H. H. Smith).

The female of G. vinula was unknown to Stal; it has the last ventral segment

sinuate at the apex on both sides and strongly, though narrowly, excised in the

middle.

In this variety the head and pronotum are orange-scarlet, with brownish-green markings; on the front of the

pronotum there are four distinct small black spots (the type-form usually has two, but sometimes four are

present); the characters of the female are identical with those of the typical G. vinula.

spots in front, and occasionally with larger or smaller markings ; scutellum large, variegated with fuscous

in front, immaculate behind; tegmina testaceous, with the internal margin broadly dark: when they

are joined, these markings form a broad band down the middle, and just at the centre is a more or

less distinct dark patch, which makes the band appear denticulate, this becoming less conspicuous or

disappearing towards the apex, the veins alone being dark ; underside and legs light testaceous.

STRAGANIA.

Stragania, Stal, Bidrag till Rio Janeiro-Traktens Hemipter-Fauna, ii. p. 49 (1858).

Stal, in his work on the Rio Janeiro Hemiptera, treats Stragania as a “new

subgenus” of Gypona, and places under it three small insects of 4-41 millim. in

length, which he names Gypona ornatula, G. divisa, and G. pallescens. These latter

are said to resemble the species ef the genus Zinneca, Am. et Serv., in size, and he is

of opinion that they ought perhaps to be separated from Gypona on account of the

structure of the tegmina and scutellum (“scutello apice haud acute producto, longitu-

dine latiore; tegminibus pellucidis, breviter pilosulis vel setulosis, non nisi apice

venulis tribus longitudinalibus brevibus instructis”). In the ‘Hemiptera Mexicana,’

STRAGANTA. 317

published six years afterwards (1864), he describes two species of the genus from

Mexico under the generic name of Stragania. We do not possess an example of either

of these in our collection, and I include them here under the Gyponide on Stal’s

authority and append his descriptions. They are small insects, with hyaline or

subhyaline tegmina, and resemble Jasside rather than Gyponide.

Nore.—Since the publication of the preceding page, I find that Stal subsequently

included Stragania under the Jassidwe as being synonymous with Macropsis, Lewis

This species seems somewhat doubtful, and Mr. Buckton, in his Monograph, marks

it with a note of interrogation. The specimen on which it is described is evidently

imperfect, and it is probably one of the many varieties of M/. mexicana, Guér.

Hab. Centra AMERICA 2,—Soutn AMERICA |.

According to Buckton, there are several specimens of this insect from Central

America in the National Collection ; but I think there must be some mistake about

this locality, as I have carefully examined ail the examples in the Museum collection.

Phyllotropis is, at most, a subgenus of Membracis. The same author (J. ¢. pp. 35, 41)

places M. mexicana under both Membracis and Phyllotropis ; on page 40 he gives my

Membracis humilis as a synonym of Phyllotropis trifasciata, Stal, but on page 43 he

describes the species as Phyllotropis humilis, and copies the figure from the ‘ Biologia’

Polyglypta godmani, Distant, Trans. Ent. Soc. 1900, p. 694°.

Hab. Costa Rica, Irazu (Rogers !), San José (Biolley 2).

Mr, Distant has again revived this species, which I have treated as synonymous with

P. costata, Fairm.; the question is discussed on page 123 of the present volume.

22. Entylia mesta.

Enitylia mesta, Buckton, Trans. Linn. Soc., Zool. (2) ix. p. 332, t. 21. figg. 11, 11 @ (1905) '.

Hab. Mexico! (Mus. Madrid).

23. Entylia cedipus.

Entylia edipus (edipus), Buckton, Mon. Membr. p. 183, t. 39. figg. 3, 3a, 6 (1908) ’.

Hab. Mexico, Chilpancingo in Guerrero |.

This name cannot stand, as the insect is identical with /. mira, Butl. (Cist. Ent. ii,

p-. 211, t. 3. fig. 7); # mira itself is a variety of &. sinuata, F., and as such I have

figured it on Plate VIII. fig. 12, of the present volume.

24. Adippe heretica,

Adippe heretica, Distant, Trans, Ent. Soc. 1900, p- 694.

Mr. Distant is of opinion that his Adippe maculata [Ent. Monthly Mag. xvi. p. 11

(1879) ] is distinct from the insect to which I have given that name (anted, p. 134, t. 8.

figg. 15, 15 a), and assigns the name A. heretica to the species figured in this work.

25. Leptocentrus canescens.

29. Clastoptera bimaculata.

Clastoptera bimaculata, Baker, Ent. News, xi. p. 464 (1900) ’.

Hab. Mexico, Vera Cruz (Heyde ').

The following corrections must be made :—

Gargaropsis, Fowler (anted, p. 167), is, apparently, not a Membracid ; according to

Ball [Psyche, ix. pp. 128-130 (1900)] it is synonymous with Macropsis, Lewis, but this.

seems doubtful. It is very different from Stragania, which Stal considers synonymous

with the same genus. | _

Salvina Chinata

Tettigonia dorsisignata and Ff. rubescens (anted, p. 282) must be referred to the

Jasside, but their generic location is at present doubtful; in some of these insects

there are bright spots between the eyes, which look like ocelli, unless closely examined,

and are very misleading.
