INTRODUCTION.

Tuis Volume contains an enumeration of the species of the following Families

of Rhynchota-Heteroptera—Tingitide, Phymatide, Aradide, Hebride, Hydrometride,

Henicocephalide, Reduviide, Nabide, Anthocoride, Ceratocombide, Cimicide, Saldide,

Pelogonide, Gelastocoride (Galgulide), Nepide, Naucoride, Belostomide, Notonectide,

and Corixide. ‘The first twelve of these belong to the Gymnocerata (Geocorise),

concluding that portion of the work contributed by Mr. Distant in Vol. I., and the

remainder to the Cryptocerata (Hydrocorise). 7

The Tingitide include a large number of species, all of small size, some of them

having the pronotum inflated, the margins of the latter, and the scutellum and elytra

also, being often more or less diaphanous, with very conspicuous nervures. But

little attention has hitherto been paid to the tropical forms of this family, and it is

therefore not surprising that sixty-six of the seventy-eight species enumerated prove

to be new, with seven new genera. Lethierry and Severin in their Catalogue (1896)

give 335 species for the whole world. Of the American genera characterized by Stal,

all but three are represented. | i

The Phymatide is a well-marked family of small extent, its members having very

strong raptorial anterior legs. Some of the species are gregarious, and they have the

habit of secreting themselves in flowers for the purpose of securing the small insects

that may come within reach. Three genera and nineteen species are enumerated, one

of them, Agreuocoris nowalhieri, being probably eastern, though said to be from

Mexico; eight species are treated as new. Herr A. Handlirsch’s Monograph of these

interesting Hemiptera was issued immediately after the publication of my own

enumeration of the Central-American forms ; the lithographic plates accompanying his

work were drawn by Baron Max v. Schlereth, and they are perhaps the most beautiful

delineations of Heteropterous insects that have ever appeared.

v1 INTRODUCTION.

The Aradide, so far as at present known, have the same number of representatives

as the Tingitidee within our limits. They are nearly all found under the bark of

fallen or decaying trees, often in gloomy places in the forest. Some of them have

the upper surface more or less coated with a hard pallid incrustation, which is moulded

into peculiarly-shaped prominences on the head, pronotum, and scutellum, the use of

which it is difficult to understand. Seventy-eight species are enumerated, with forty

new, and five new genera.

The Hebride is a family of very limited extent, the species all being of subaquatic

habits. Eleven species are here recorded, seven of them being treated as new.

The Hydrometride are spread over all parts of the world, many small islands

having one or more representatives, and some of the genera are very widely distributed.

They live upon the surface of fresh, brackish, or salt water. Within our limits, the

subfamily Veliine, so far as can be judged from the collections obtained by our

Editors, is much more numerous in species than the Gerrine; but as the latter are

usually very difficult to secure, this may not really be the case. For the whole

family (exclusive of the pelagic Halobatine, which are not dealt with here) forty

species are enumerated, including twenty-nine previously undescribed, and two new

genera.

The Henicocephalide is a widely distributed family including but few species. The

single American genus is known under various different names. These insects have

the head very peculiarly formed, the anterior legs raptorial, and the elytra uniformly

membranous, so that they can be readily used for flight. Of the six species enumerated,

all but one are treated as new.

The Reduviide is one of the most extensive families of Heteroptera. They are

chiefly confined to the tropics, becoming much less numerous in temperate regions.

Lethierry and Severin (1896) enumerate 1877 (counted up in their summary as 1835)

species for the whole world, exclusive of the Nabide. Amongst the known Tropical-

American genera there are a considerable number that do not extend so far north

as the Isthmus of Panama, while, on the other hand, Apiomerus, Zelus, &c. are

particularly well represented. These insects are all blood-suckers, Conorrhinus being

said to attack man, and many of them have the power of exuding a viscous liquid

for the purpose of retaining a secure hold of the species upon which they prey. The

INTRODUCTION. vil

flattened forms living under bark (Leogorrus, Homalocoris, &c.) emit a very offensive

odour. 204 species are here recorded from Central America, seventy-eight of which

are treated as new, with seven new genera.

The Nabidze (by some authors treated as a subfamily of Reduviide) include about

150 known species, nearly half of which belong to the genus Nadis, and most of

these being palearctic. Some of the other genera are tropical. Fourteen species are

enumerated from within our limits, two being described as new, with one new genus.

The Anthocoride are all of very small size, some of the smallest known Heteroptera

belonging to this family. Very little attention has been paid to them by collectors

in the tropics, owing perhaps to their extremely delicate structure, though the group

was monographed by Dr. O. M. Reuter in 1884. Some species abound in the

Antillean islands. The most characteristic genus in Central America is Macrotrachelia,

which bears a strong superficial resemblance to some of the Thripide. Fifty-four

species are enumerated, with thirty-two new, and seven new genera.

The Ceratocombide is represented in our collections by a single species of the

typical genus Ceratocombus. Of the subfamily Schizopterine, however, there are

five genera known from the Antilles or Tropical South America, all very peculiar

forms; and one or more of these will sure to be found eventually in Central America,

Prof. Uhler, indeed, having incidentally noted the presence of Schizoptera in our

region. They are all minute, delicate insects, living upon the banks of streams, or in

moss &c. Recent investigations have shown that they are particularly numerous in

some of the smaller Antillean islands.

The Cimicide includes the bed-bug and its allies. ‘Two species only have come

to hand as yet from Central America, one of them being the universal pest mentioned,

and the other infesting poultry, the latter being taken as the type of a new genus.

As they are known to attack bats and various birds, many additional forms doubtless

remain to be discovered.

The Saldide (termed Acanthiide by some authors) are represented in almost every

part of the world by one or more species of the typical genus Salda, insects living

upon the banks of ponds and rivers, as well as in salt-marshes, &c. The subfamily

Leptopodine is confined to the eastern hemisphere. Ten species of Salda are here

Vili INTRODUCTION.

enumerated from Central America, seven of these being treated as new; but many

more must inhabit the region.

The Pelogonide, by some authors treated as a section of the Gelastocoride

(=Galgulide, olim), is the first family of the division Cryptocerata. The various

species are superficially very like the Saldide and have the same habits. Four are

now known from within our limits, three of them being described as new.

The Gelastocoride (a term recently applied to the Galgulide, on account of the

name Galgulus, from which it is derived, being long preoccupied in Aves) are

particularly abundant in Central America, both genera being characteristic of the

region. As already noted, the species of Gelastocoris (Galgulus) have much the

appearance of small Batrachians, and they also have the power of leaping. Like

Mononyz, they live on the banks of lakes and streams. For the two genera ten species

are enumerated, but the new ones are not described, a monograph of the genus

Gelastocoris being in course of preparation by Mons. A. L. Montandon of Bucarest.

The Nepide is a family of very limited extent, including the typical genus Mepa

(the well-known ‘“ water-scorpion ”), Ranatra, and a few allied forms. In Tropical

America Nepa is replaced by Curicta, with two species in our region, where Ranatra

has also two representatives.

The Naucoride are fairly numerous in Central America, but very little material has

been obtained by us. These insects have, however, during recent years received a

good deal of attention from M. Montandon, who has examined or described all the

species contained in the principal continental museums, and the types of most of the

Central-American ones have been lent us for figuring. Some of the species live in

stagnant, others in fresh water. Nineteen are here recorded, one only being new.

The Belostomide include the largest known forms of Heteroptera, some specimens

of the typical genus Belostoma, B. grande, measuring over four inches in length. Five

genera and thirteen species are enumerated from Central America, all previously

described. Most of the specimens in collections, at least of the genus Belostoma,

appear to have been attracted to light, comparatively few, apparently, having been

taken with the water-net. In the United States they are known by the name of

“ electric-light bugs.” | a | _

INTRODUCTION. 1X

The Notonectide, or ‘‘water-boatmen,” are represented within our limits by three

genera only, Motonecta, Anisops, and Plea, the first two by the same number of

species. Of the eleven forms noticed, four of the Anisops are treated as new.

The Corixide are so poorly represented in our collections that very little can be said

‘about them. Various Corize recorded from within our limits are unknown to me,

and of several of the other species of that genus but few specimens are available for

examination. Nevertheless, one of them, C. mercenaria, abounds to an incredible

extent in the lagoons of the central plateau of Mexico, and this shows that we can

have no idea at present of the actual number of Central-American forms. Thirteen

species of Corixa, six of which are treated as new, and one of Tenagobia, are enumerated,

but it is almost certain that some of the former will prove to be synonymous when

the types can be compared.

The number of species for the nineteen families is 592, with 289 new and

thirty new genera. For the first twelve of these families Lethierry and Severin (1896)

give 3144* species for the whole world, as against our 517. In Vol. L., for the

families Pentatomide, Coreide, Lygzide, Pyrrhocoride, and Capside, 1108 species

are enumerated, with 581 new. The total number of Heteroptera recorded in this

work (including the fifteen additions to Vol. I., noticed on p. 384) is therefore 1715,

rather more than half of which have been treated as new.

We are again much indebted to the authorities of the Stockholm, Vienna, and

Berlin Museums, as well as to Dr. E. Bergroth and Mons. A. L. Montandon, for the

loan of various types or co-types, many of which are figured on our Plates. Of these

latter, twenty-two have been required, six of which are coloured, the whole of them

having been carefully drawn by Mr. E. Wilson of Cambridge.

Mr. Distant, in his Introduction to Vol. I., has already noted the sources from

whence our collections have been derived, and his remarks apply equally well to the

insects dealt with in the present volume.

* These figures, however, are much too high in reality (many of Walker’s so-called species being

counted), notwithstanding that there is a mistake in adding up, the actual number being 3186.

ZOOLOGIA.

Class INSECTA.

Order RHYNCHOTA.

Suborder HEMIPTERA-HETEROPTERA (continued).

Fam. TINGITIDA*.

This interesting family of Heteroptera is well represented within our limits, and

includes some very remarkable insects, the modifications in the form of the pronotum in

some of them (Dicysta, Meyalocysta, &c.) being suggestive of what isto be found in the

Membracide. Of the seventy-seven species here enumerated, sixty-five are described as

new. All the American genera characterized by Stal f are, however, represented, with

the exception of Stephanitis, Leptocysta, and Spherocysta, and seven others are added.

In the descriptions of the new genera and species the following terms are used for

the several portions of the elytra: (1) discoidal area; (2) subcostal area (the costal

area of Stal), the outer limit of this area corresponding with the exterior edge of the

abdomen when the elytra are closed; (3) costal area (the costal membrane of Stal) ;

(4) sutural area (the membrane of most authors, exclusive of the small narrow basal

piece covered by the posterior portion of the pronotum). In the group Tingitini the

scutellum is completely covered by the prolonged triangular posterior portion of the

pronotum f{ and the clavus is obsolete. ;

The terms ‘‘ forma macroptera” and “forma brachyptera,” used by Stal and others

for forms of the same species, do not seem to be required here. All the specimens

examined of the genera Acanthochila, Leptobyrsa, Gargaphia, &c. have short wings,

and those of Améblystira, Teleonemia, Monanthia, &c. long wings. ‘The sex of

the specimens described below is only mentioned in a few cases, as it cannot always

be ascertained without taking the insects off the cards upon which they are mounted.

The males of some (or perhaps all) of the species have a pair of curved, clasping, pincer-

like processes at the end of the abdomen *.

In some of the figures on Tab. II. our artist has incorrectly placed the left elytron

uppermost: the right elytron usually overlaps in repose, but this is not always the case.

We are indebted to Prof. Aurivillius, of the Stockholm Museum, for the loan of

many of Stal’s types, including those of all his American genera; also to Herr A.

Handlirsch for the whole of the Mexican Tingitide belonging to the Vienna Museum.

The three Central-American species referred to it agree well with Fieber’s structural

figures, except that the middle coxe are not so widely separated from the hind coxe

and the margins of the pronotum are less acutely bispinous. They agree in the

following particulars :—

* Figured by Fieber, Géldi, and A. Dugés.

PHATNOMA. 3

Rostrum extending to far beyond the metasternum ; rostral groove parallel and nearly reaching the last ventral

suture; buccal lamine prominent, projecting beyond the front of the head, closing the rostral groove

anteriorly ; antenne moderately long, widely separated, exceedingly slender, with joints 1 and 2 stouter,

smooth, and short, 3 very elongate, 4 somewhat fusiform at the tip and longer than 1 and 2 united; head

elongate-triangular, with three stout porrect frontal spines, two slender spines behind and two others in

front, and slender, spiniform, antenniferous tubercles; pronotum with the base truncate and bisinuate,

leaving the small scutellum exposed, the submembranous margins acutely dilated at the sides and in front,

and closely reticulated, the areole more or less hyaline, the disc tricarinate, the outer carine abbreviated

in front; elytra with well-defined clavus and sutural, discoidal, subcostal, and costal areas, the discoidal

DICYSTA.—MEGALOCYSTA. 5

Group TINGITINI.

DICYSTA, n. gen.

Rostrum reaching the end of the metasternum. Rostral groove broad and subparallel beyond the front coxe,

uninterrupted, closed in front, the sternal and buccal lamine prominent. Antennz glabrous, distant at

the base, long and slender, joint 1 slightly thickened and twice as long as 2, 3 very elongate (4 broken

off). Head with a short, obtuse frontal spine. Pronotum with greatly dilated, concave, reflexed, membra-

nous margins, these being subvertical, shell-like, and rounded; hood oval, exceedingly large, completely

covering the head, and connected posteriorly by the strongly foliaceous median carina with an equally

large bladder-like process arising from the triangular posterior portion of the pronotum, the posterior

process abruptly truncate in front, the margins and processes widely reticulated. Elytra entirely hyaline,

twice as long as the abdomen, obliquely widening at the base, parallel from about the basal third to the

rounded tip, the apical margin oblique; discoidal area about reaching the middle, curved and sharply

raised externally, becoming more inflated behind ; costal area broad ; median nervure strongly sinuous ;

reticulation wide and subequal. Orifice not visible. Legs slender.

The single species referred to this genus resembles the most exaggerated forms of

Leptostyla in the form of the pronotum, except that the foliaceous median carina is

developed behind into avery large bladder-like process, similar to the hood in size and

shape, this character also separating it from Stephanitis, Corythucha, &c. ‘There is no

trace of outer carine on the pronotum. ‘The wings are short.

1. Dicysta vitrea, n. sp. (Tab. I. figg. 4; 4a, profile.)

Moderately elongate, broad, glabrous ; body testaceous, darker beneath, the membranous integument hyaline,

with the nervures brown, those on the crest of the pronotal processes obscure fuscous, the elytra with a

faint transverse fuscous fascia on the costal area at about one-third from the base, the tips of the tibie

and the tarsi slightly infuscate; the whole of the reticulation wide. LElytra broader than the pronotum ;

discoidal area with three, the subcostal area with two, rows of areole; costal area with four rows of

areole at the middle, diminishing to two at the base.

Length 32, breadth 2 millim. (d.)

Hab. Panama, Volcan de Chiriqui (Champion).

1-3 smooth and almost glabrous, 4 pilose. Head with very short frontal spines. Pronotum with

moderately broad, widely reticulated membranous margins; hood oval, enormously large and inflated,

slightly constricted at the middle, covering the base of the head and extending halfway across the

elongate-triangular posterior portion of the pronotum, the latter carinate down the centre. LElytra

hyaline, extending to far beyond the abdomen, gradually widening to the basal third, the costal margin

hollowed at the middle, the apex bluntly rounded; discoidal area nearly reaching the middle, raised

6 HEMIPTERA-HETEROPTERA.

strongly sinuous; reticulation very wide. Wings not extending beyond the abdomen. Legs slender,

the knees distinctly swollen on the upperside. Orifice prominent, surrounded by a transverse raised

carina.

The single species included in this genus may be readily distinguished from Dicysta

and the allied forms by the articulation of the third and fourth joints of the antenne.

The pronotal hood is enormously large, long, and swollen.

1. Megalocysta pellucida, n.sp. (Tab. I. figg. 5; 5a, profile; 56, antenna;

5c, part of the body beneath.)

Moderately elongate, rather broad; body ferruginous, the disc of the pronotum sometimes blackish, the

integument pale testaceo-hyaline and glabrous, the nervures of the pronotal hood more or less fuscous, the

elytra usually with a faint curved fuscous fascia towards the apex, and sometimes the apical row of

areole also slightly infuscate; the legs and antenne ferruginous or testaceous, the apical joint of the

latter black. Pronotum with the membranous margins rounded and feebly raised, with a single row of

large tetragonal areole; the hood very widely reticulated, the areole tetragonal or pentagonal ; the disc

on each side of the hood closely punctured. Elytra with the sutural and costal areas subequal in

width beyond the discoidal area; the costal area depressed, with three rows of large areole at the middle,

diminishing to two at the base; subcostal area vertical, triseriate, the external areole very minute.

Length 42, breadth 21 millim.

CORYTHUCHA.

Corythucha, Stal, Enum. Hemipt. iii. pp. 119, 122 (1873).

The described members of this genus are all American (North and South), save

one, and that will probably have to be separated. The species seem to be fairly

numerous in the United States, and also in Central America, whence five are now

enumerated *. They may be differentiated as follows :—

Pronotal hood large or moderately large, globose behind; median carina

foliaceous.

Marginal spines of the pronotum and elytra rather short and slender.

Elytra broadly bifasciate ; areolz of the sutural area very unequal in size. fuscigera, Stal.

Elytra with faint transverse darker lines, sometimes forming three fasciz. decens, Stal.

Elytra with a post-basal fascia and some spots on the nervures towards

the tip toe ee ee ee ee ww wwe untfasciata, n. sp.

Marginal spines of the pronotum and elytra longer and stouter; elytra

(Champion); Panama, Bugaba, Volcan de Chiriqui (Champion).— ANTILLES, Grenada +.

In this small species the discoidal area of the elytra is more widely reticulated than

in the other Central-American members of the genus. Some specimens have the

median carina of the pronotum moderately foliaceous (it being much less prominent

than the hood, when viewed laterally), and the nervures of the elytra distinctly marked

with fusco-testaceous; while others have the median carina very strongly foliaceous

and the elytral nervures faintly marked with testaceous. Both forms were obtained at

Pantaleon. C.decens is probably a variety of C. gossypz (Fabr.) ; the type is immature.

An example from Guatemala city is figured.

3. Corythucha unifasciata, n. sp. (Tab. I. figg. 8; 84, profile.)

Body black, the pronotum brown, except in front; the integument whitish or pale testaceous, the membranous

margins of the pronotum and the elytra in great part hyaline; the pronotum with the nervures of the hood

and two transverse marks on the margins, and the elytra with a transverse fascia a little below the base,

some small spots or some of the nervures near the tip, and sometimes one or two spots on the discoidal

area, brownish or fuscous; the legs and antenne testaceous, the latter with the apical joint usually

darker; the pronotum with the margins, hood, median carina, and nervures, and the elytra with the

costal margin to near the apex, and also the nervures, armed with rather short closely-set spines, those

on the margins of the pronotum and elytra becoming shorter behind; the antenne with long bristly

hairs. Pronotum with the membranous margins broad, reniform ; hood large, abruptly constricted at the

middle, tapering in front and globose behind, widely reticulated, the reticulation becoming much closer

at the sides in front; median carina strongly foliaceous, the outer carine raised anteriorly. Elytra with

the discoida]l area rather closely reticulated, tumid behind ; costal area with three rows of areole, the

areole large, except towards the base, tetragonal or pentagonal.

Chiriqui (Champion).

Fifteen examples. Very like C. spinosa, but differing from it in having shorter and

more slender spines along the margins of the pronotum and elytra, as well as on the

nervures. The three specimens from Mexico are all more or less immature. Smaller

than C. fuscigera, the elytra without a transverse fascia near the apex. C. hispida, Uhler,

from Lower California, is also an allied form. A specimen from Chiriqai is figured.

Hab. Mexico (Sallé), Guanajuato (Dugés1), Orizaba (Bilimek, in Mus. Vind. Ces.).

Differs from C. fuscigera in having much longer and stouter spines along the lateral

borders of the pronotum and elytra, as well as on the nervures, the pronotal hood

much less inflated behind and more widely reticulated at the sides in front, and the

maculation of the apical half of the elytra in the form of scattered spots. ‘The fuscous

markings are probably variable, as none of our specimens quite agree with Duges’s figure

in this respect. The details of structure of both sexes and the larva are figured by

him. We figure a specimen from the Sallé collection.

5. Corythucha setosa, n. sp. (Tab. I. figg. 10; 10a, profile.)

Body black, the pronotum brown, except in front; the integument whitish or pale testaceous, the membranous

margins of the pronotum and the elytra hyaline; the pronotum usually with one or two transverse

marks on the margins and the crest of the hood, and the elytra with a transverse fascia a little below

the base, and generally some of the nervures near the tip, brownish or fuscous; the antenne and legs

testaceous; the pronotum with the margins, hood, and nervures, and the elytra with the costal margin

to near the tip, as well as the nervures, armed with rather short. closely-set spines; the antennz with long

bristly hairs. Pronotum with the membranous margins broad, reniform ; hood moderately large, gradually

tapering forwards, not constricted at the middle, the reticulation uniform; median carina very feebly

foliaceous, becoming still lower in front, the outer caring also very little raised. Elytra with the

discoidal area closely reticulated, slightly tumid behind; costal area with three rows of areole, the

areole large, tetragonal or pentagonal.

Length 31-33, breadth 2-23 millim.

Not uncommon in Guatemala, at an elevation of from 5000-9000 feet above the

sea. Differs from the other Central-American species in the much smaller, narrower,

and gradually tapering pronotal hood, the very feebly raised median carina of the

pronotum, and the less tumid discoidal area of the elytra. A specimen from Cerro

Zunil is figured.

GARGAPHIA.

Gargaphia, Stal, Enum. Hemipt. iii. pp. 119, 124 (1873).

In this genus the rostral groove is interrupted between the meso- and metasternum

by a prominent, sinuous, transverse carina, a character separating Gargaphia from the

rest of the Tingitide. Four species only from Central America belong to it. They

may be differentiated thus :—

One of the commonest and most widely distributed species of ‘Tingitinz in Central

America. The transverse blackish or fuscous cloud on the pronotal margins is

frequently obsolete, and the margin itself in some specimens is more narrowly

foliaceous, with fewer areole. The elytra have a more or less distinct transverse

blackish fascia on the irregularly reticulated costal area at about one-third from the

Hab. Panama, Bugaba, David, and San Lorenzo in Chiriqui (Champion).—Co.ombia,

Found in plenty in the “tierra caliente” of Chiriqui. Described from a single

example. In this species the anterior margin of the pronotum and the antenne are

sparsely pilose, and the discoidal area of the elytra is abruptly closed behind by a

transverse oblique raised nervure. G. nigrinervis is extremely like G. trichoptera, Stal,

also from Colombia; but it is smaller, and differs constantly from it in the angularly

dilated pronotal margins. Both species have three or four oblique blackish nervures in

the costal area of the elytra. A specimen from David is figured.

3. Gargaphia panamensis, n. sp. (Tab. I. figg. 14; 14a, profile.)

Moderately elongate ; ferrugineo-testaceous, the body black beneath, the margins of the pronotum and the

elytra subhyaline; the antenne testaceous, with the basal and apical joints black ; the legs testaceous,

with the tarsi and the greater part of the tibie infuscate; the margins of the pronotum and the costal

margin of the elytra to about the middle very minutely denticulate. Head with three short slender

frontal spines, meeting at the tip; antenne long and slender, joint 1 three times as long as 2 and nearly

as long as 4, 2 very short. Pronotum with the membranous margins moderately wide, rounded in front

and behind and slightly recurved, with three rows of small areole; hood rather small, oval, compressed,

angularly projecting in front; the three carine feeble, foliaceous, the interspaces closely, finely punctate.

Elytra moderately long, arcuately widened from the base, broadly rounded at the tip; discoidal area

narrow, barely one-third the length of the elytra, closely reticulated; subcostal area as wide as the

discoidal, closely reticulated ; costal area with four rows of areole at the middle, diminishing to three

at the base, the areole, except towards the base, where they are small, moderately large and (ke those

of the sutural area) subequal in size,

Length 24, breadth 13 millim.

Hab. Panama, Caldera in Chiriqui (Champion).

One specimen. In this small species the rostral groove is interrupted between the

meso- and metasternum by a prominent transverse carina, and the insect is, therefore,

a true Gargaphia. ‘The anteriorly constricted pronotum makes the membranous

margins appear much broader in front. It is prubable that fresh specimens have the

pronotal margins ciliate.

4, Gargaphia iridescens, n. sp. (Tab. Il. figg.* 1, 1 a.)

Moderately elongate; body black, the integument yellowish-white, the elytra with the discoidal area slightly

infuscate at the base and apex, the apical portion of the nervure limiting it externally fuscous, the costal

area and the greater part of the sutural area hyaline and iridescent, the costal area with three or four of

the transverse nervures in the basal half blackish and the other nervures pale; the antenne with joint 1

black and 2 testaceous (the others broken off); the legs testaceous, with the tarsi blackish at the tip; the

pronotum and the nervures on the basal half of the elytra set with erect hairs. Head with five slender

spines; antenne with joint 1 about twice as long as 2. Pronotum with the membranous margins raised

and moderately wide, subangularly dilated before the base, and rapidly and obliquely converging thence

to the apex, with two rows of areole; hood small, oval, slightly projecting in front; the three carinz

moderately foliaceous, the interspaces closely punctured; the triangular posterior portion membranous

and reticulated. Elytra extending to far beyond the abdomen, oblong-oval, slightly constricted at the

middle, broadly rounded at the apex; discoidal and subcostal areas closely reticulated, the discoidal area

not reaching the middle, the subcostal area triseriate; costal area with two rows of large, mostly

tetragonal areole, increasing to three in the widest part and diminishing to one at the tip; sutural

area (the inner basal portion excepted) with large areola. |

Hab. Nort Mexico, Juarez on the Rio Grande, opposite El Paso (Cockerel?).

We are indebted to Mr. Cockerell for a specimen of this species. It cannot be

identified with any of the described North-American forms. Tingis (Gargaphia) tilie,

Walsh, is perhaps an allied insect.

LEPTOSTYLA.

Leptostyla, Stal, Enum. Hemipt. i. pp. 120, 125 (1873).

Numerous Central-American species are referred to this genus *, but the characters

given by Stal require amplification to include them: the basal joint of the antenne

varies in length from about two to five times that of the second, the pronotal hood is

sometimes very large, and the membranous margins of the pronotum are sometimes

very broad, according to the species. The antenne are long and slender, with a more

or less elongate basal joint, and a still longer fourth joint. The pronotum is tri-

carinate, except in L. tumida. The elytra are gradually widened at the base, extending

to far beyond the apex of the abdomen; the costal and sutural areas are more or less

widely reticulated. the reticulation of the latter usually being very unequal towards the

tip; the median nervure is strongly sinuate; the discoidal area is flat, sometimes

the subcostal area (costal of Stal) is sometimes very narrow, with one or two rows of

Hab. Panama, Bugaba (Champion).

Two examples, one of which has unfortunately lost the head and pronotum. Differs

from its allies in the greatly distended vertical, shell-like, concave membranous margins

of the pronotum, small discoidal area, widely divergent elytra, and very long basal joint

of the antenne. Viewed laterally, the pronotum appears to have four foliaceous

the middle and a spot on the median carina, fuscous; the antenne and legs testaceous, the latter with

the tips of the tarsi infuscate. Head with a slender frontal spine and two shorter ones below it; antennwy

long and slender, joint 1 rather more than three times as long as 2 and nearly as long as 4, 2 very short.

Pronotum with the membranous margins enormously dilated, recurved, and rounded, widely reticulated,

there being about four rows of areole in the widest part; hood enormously large and inflated, oval,

covering the whole of the disc of the pronotum and the head also (the eyes excepted), and connected

posteriorly with the strongly foliaceous short median carina. Elytra moderately long, narrow at the

base and then gradually widened (the basal portion of the costal margin appearing slightly sinuous),

rounded at the tip; discoidal area rather short, somewhat piriform and slightly raised; subcostal area

vertical, biseriate behind, uniseriate in front; costal area with three rows of areole at the middle,

pronotum; but it has the discoidal area of the elytra much smaller and only slightly

raised (instead of large and tumid), the basal joint of the antenne elongate, &c. The

pronotal hood covers the whole of the disc, the short median carina behind it being

strongly foliaceous; the outer carine are obsolete.

Moderately elongate, narrow, widening behind; body black, the integument whitish and hyaline; the elytra

with an oblique fascia extending from about the middle of the inner margin to near the tip and continuing

round it, and the pronotum with some of the nervures of the hood and of the foliaceous carina behind it,

fuscous; the antennee testaceous, with the basal joint (and probably the apical one also) black; the legs

testaceous, the tarsi slightly infuscate; the pronotum with the margins and the summit of the dorsal

appendages, and the elytra with the costal margin to near the apex and the nervures, set with short fine

sete. Head with three long spines—one frontal and two lateral; antenne indistinctly pilose, long

and slender, joint 1 three times as long as 2, 2 very short. Pronotum with the membranous margins

broad, recurved, and rounded, with three rows of areole; hood very large, oval, widely reticulated ;

of the pronotum and elytra, the pronotum with the hood very much larger, the median

carina strongly foliaceous, and the membranous margins broadly, arcuately dilated and

triseriate, the elytra with the discoidal area less closely reticulated and the costal

margin more sinuous.

spines; antenna pilose, slender, elongate, joint 1 three and a half times as long as 2, 2 very short, 4

much longer than 1. Pronotum with the membranous margins moderately broad, recurved, converging

in front, with two rows of areole; hood rather short, broad-oval, considerably raised; the long median

earina strongly foliaceous, becoming lower in front, with a single row of large transverse areolew, the

outer carine moderately foliaceous; the posterior triangular portion membranous, Elytra long,

widening from the base, rounded at the tip; discoidal area extending very little beyond the basal third,

rather widely reticulated ; subcostal area narrow, biseriate; costal area with two rows of areole at the

middle and one at the base, the areole large, those at the base strongly transverse; the areole in the

apical half of the sutural area very unequal in size, two of the inner ones being very large and pentagonal.

Length 33, breadth 13 millim.

Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith).

One specimen. The chief characters of this species are the pilose margins of the

pronotum and elytra, the large areole of the costal area of the elytra, uniseriate at

the base and biseriate at the middle, and the moderately wide biseriate membranous

margins of the pronotum.

6. Leptostyla fuscofasciata, n. sp. (Tab. I. figg. 20; 20 a, profile.)

Moderately elongate, narrow ; body black, the integument whitish and hyaline; the elytra with an oblique

Length 24, breadth 13 millim.

Hab. Panama, Bugaba (Champion).

Five specimens. Differs from all the other allied forms in the very wide reticula-

tion of the elytra, the areole being comparatively few in number, this character (and

the black second joint of the antennz) separating it at once from L. gracilenta,

L. angustata, &c.

7. Leptostyla elata, n. sp. (Tab. I. figg. 21; 21a, profile; 210, part of

the body beneath.)

those of the sutural area also, moderately large. Rostrum reaching the meso-metasternal suture.

Length 34-4, breadth 2-24 millim.

Hab. Mexico, Amula in Guerrero (H. H. Smith); Guatemata, San Isidro, Pantaleon,

Capetillo, San Gerénimo (Champion).

Found in numbers in Guatemala, singly in Mexico. This insect is very like

Gargaphia nigrinervis in general shape ; but differs from it in having the rostral groove

uninterrupted by a transverse carina between the meso- and metasternum, the basal

joint of the antenne longer, &c. Following Stal’s arrangement, the species would

have to be placed in his third section of the genus, near L. furcata. A specimen

from San Gerénimo is figured.

Length 3, breadth 14 millim.

Hab. Guatemata, San Isidro (Champion).

One example. Lasily distinguishable by the narrow, straight, oblique, smoky-black

fascia of the elytra, and the large areole of the costal and sutural areas, those of the

with two series of rather large areole in the costal area of the elytra from the base

downwards, the median carina of the pronotum more raised than the outer ones.

10. Leptostyla angustata, n. sp. (Tab. I. figg. 24; 24a, profile.)

Hab. Guatema.a, Zapote, Capetillo, and Guatemala city (Champion).

Numerous examples. Differs from the allied forms in the very narrow elytra, these

when closed being of about the same width as the pronotum. The pronotal hood is

small and somewhat compressed. L. tenuis approaches L. angustata, but has less

elongate elytra, these (when closed) being much narrower at the tip; the antenne and

legs much shorter, &c. A single damaged, discoloured specimen from Duefias,

Guatemala, perhaps belongs here: it has the basal joint of the antenne pale; the

elytra longer, with the nervures brownish, and the costal area with a single row of

areole towards the base.

12. Leptostyla dilaticollis, n. sp. (Tab. II. figg. 2; 24, profile.)

Moderately elongate, rather broad; body black, the integument testaceous and partly hyaline, the elytra with

Hab. GuatemaLa, Cahabon in Vera Paz (Champion).

One example. This insect approaches L. difasciata, but has the pronotum more

transverse, the membranous margins being much broader and with more numerous

areole. The reticulation of the elytra is also more uniform and the markings quite

different. The frontal spines are so small as to be scarcely distinguishable.

base, the costa thence to near the apex straight, the apex broadly rounded ; discoidal area subfusiform,

not reaching the middle, closely reticulated; subcostal area narrower than the discoidal, irregularly

triseriate; costal area with three or four rows of areole at the middle, diminishing to two at the base,

the outer and inner areole at the middle larger than the others; the areole in the apical half of the

sutural area also very unequal in size, two of the inner ones being very large and pentagonal.

Length 33, breadth 17 millim.

Hab. Guatemata, Senahu in Vera Paz (Champion).

One specimen. Easily recognizable by the bifasciate elytra and the rather broadly

dilated membranous margins of the pronotum.

14. Leptostyla divisa, n.sp. (Tab. II. figg. 4*; 42, profile.)

Moderately elongate, rather broad; body black, the integument whitish or pale testaceous and partly hyaline ;

the elytra with an oblique fascia towards the apex, the space between the costal area and the inner

margin thence to the base, and the nervures beyond the fascia, smoky-black or fuscous; the antenne

areole at the middle, diminishing to two at the base; the areole in the apical half of the sutural area

very unequal in size, two of the inner ones being very large.

Length 34, breadth 14 millim.

Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion).

Twelve specimens. Not unlike the North-American L. oblonga; but without

lateral spines on the head, the elytra broader and with more numerous areole in the

costal area, the discoidal area much shorter.

15. Leptostyla furculata, n. sp. (Tab. II. figg.5*; 54a, profile; 5, part of

the body beneath.)

Moderately elongate, rather broad ; body black, the integument whitish or pale testaceous and partly hyaline ;

the elytra with the apex broadly, the large areole excepted, and the space between the costal area and

the inner margin thence to the base, and the nervures of the pronotal hood, smoky-black or fuscous ; the

antenne testaceous, with the apical joint, except at the base, fuscous or black; the legs testaceous.

Head with two short slender frontal spines, approximating at the tip; antenne long and slender, joint 1

scarcely more than twice as long as 2, 2 very short, 4 nearly twice as long as 1. Pronotum with the

membranous margins moderately wide, recurved, converging anteriorly, with two or three rows of

areolz ; hood short, oval, considerably raised; the three carine feebly foliaceous, the interspaces closely

punctured. Elytra moderately long, arcuately widened from the base, rounded at the tip, the costal

Length 3-34, breadth 13 millim.

Hab. Guatemaia, Senahu in Vera Paz, El Tumbador, Cerro Zunil (Champion) ;

PanaMa, Bugaba (Champion).

Found in plenty at Bugaba, rarely elsewhere. Very like Z. divisa, but easily

separated from it by the entirely pale basal joint of the antenne; the apex of the

elytra, too, is more clouded with fuscous, the larger areole excepted. The single

specimen from Senahu has the apex of the elytra clearer than usual.

L. furcata, Stal, from Rio Janeiro, the type of which is before me, is also ami allied

form ; but it has more elongate and less parallel elytra, with the oblique fuscous fascia

more distant from the apex, and the basal joint of the antenne much more elongate.

A specimen from Bugaba is figured.

16. Leptostyla constricta, n. sp. (Tab. II. figg. 6 *; 6a, profile.)

Moderately elongate, narrow, narrowed behind ; body black, the pronotum with the hood and the membranous

margins whitish, and the carine and the tip of the triangular portion pale testaceous; the elytra

testaceous, with a rather broad transverse fascia on the costal area before the middle, and the apex and

sutural area, one or more of the central areole excepted, fuscous, the rest of the costal area whitish and

hyaline, the subcostal area bordered with black externally; the antenne with joints 1 and 2 obscure

testaceous, 3 flavous, and 4 black; the legs entirely flavous. Head with two short converging spines in

front ; antenne slender, comparatively short, joint 1 barely twice as long as 2, 3 about two and one-

fourth times as long as 4. Pronotum with the membranous margins moderately wide, recurved,

converging anteriorly, with two rows of areol~#; hood short, considerably raised; the three caring feebly

foliaceous, the interspaces closely punctured. LElytra moderately long, oval, constricted at the middle,

rounded at the tip; discoidal and subcostal areas closely reticulated, the discoidal area not or scarcely

reaching the middle; costal area moderately wide, with two rows of areole; sutural area with the'

areoles very unequal in size, one of the inner ones being larger than the rest.

Length 2-23, breadth 1-1) millim. ,

Hab. Guatemata, Pantaleon (Champion); Panama, Bugaba (Champion).

One specimen from each locality. This pretty little species differs from all the other

Central- American members of the genus in the oval, medially constricted elytra and

comparatively short antenne. The Panama specimen ( @ ) is larger than the one from

Guatemala, and has the elytra longer, with the subcostal area more widely reticulated.

The Guatemalan specimen is figured.

LEPTOPHARSA.

Leptopharsa, Stal, Enum. Hemipt. iii. pp. 122, 126 (1873).

This genus, based upon two Tropical-American species, seems only to differ from

Leptostyla in the very small transverse pronotal hood, in connection with the closer

subequal reticulation of the sutural and costal areas of the elytra, the costal area

having two rows of areole, increasing to three at the middle; the basal joint of the

antenne not more than twice the length of the second. The single species from

Panama now added has the pronotum unicarinate only, and the rather stout spines on

the head biunt at the tip.

1. Leptopharsa unicarinata, n. sp. (Tab. II. figg. 7; 7 a, profile.)

Moderately elongate, rather narrow; body black, the integument testaceous and subhyaline; the legs and

antenne testaceous (the apical joint of the latter broken off). Head with three rather stout, blunt,

porrect spines—two lateral, behind, and a frontal one, placed more forwards ; antenne long and slender,

joint 1 about twice aslongas2. Pronotum narrowed and constricted in front ; the membranous margins

narrow and of nearly the same width throughout, forming a prominent obtuse angle behind, with two

rows of very small areole, diminishing to one in front; hood small, short, transverse as viewed from

above, projecting a little in front; disc densely punctured, with a single feebly raised median carina ;

posterior triangular portion membranous. Elytra long, arcuately widened from the base and broadly

rounded at the tip; discoidal area narrow, not nearly reaching the middle, scarcely wider than the

subcostal area, both closely reticulated; costal and sutural areas somewhat closely and subequally

reticulated, the costal area with three rows of areole at the middle, diminishing to two at the base.

Length 3, breadth 12 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

One example. Differs from Z. elegantula, Stal, from Bogota (the type of which is

before me), in the unicarinate pronotum, the membranous margins of which follow

the outline of the pronotum itself, and appear narrowed and constricted in front; also

in the shorter discoidal area, rather wider reticulation, and trispinous head.

22 HEMIPTERA-HETEROPTERA.

MACROTINGIS, n. gen.

Rostrum extending to the meso-metasternal suture. Rostral groove slightly narrowing to the base of the

mesosternum, and then widened out into an oval space on the metasternum, uninterrupted, closed in

front, the sternal lamine moderately prominent. Antenne distant at the base, exceedingly elongate,

extending to far beyond the apex of the elytra, slender, joint 1 very long, about twice as long as 4,

equalling the femora in length, 2 very short, 3 nearly two and a half times the length of 1, 4 lanceolate,

pilose, and stouter than the others. Head with a single long erect frontal spine. Pronotum with

moderately wide membranous margins, a rather small oval hood, and a median and two lateral carine,

the latter short, the posterior portion elongate-triangular. Elytra narrow, elongate, extending to far

beyond the abdomen, hyaline; costal area bi- or uniseriate; discoidal area not nearly reaching the

middle, the subcostal area very long and narrow; median nervure feebly sinuate. Legs very elongate

and slender. Orifice not visible.

Two closely allied species belong to this genus. The extremely elongate antenne

with relatively very long basal joint (this being about twice as long as the apical one,

and equalling the femora in length), long legs, prominent frontal spine, &c., distinguish

it from Leptostyla, to which it is perhaps most nearly allied.

1. Macrotingis biseriata, n. sp. (Tab. II. figg. 8; 8a, profile; 8 4, part of

the body beneath.)

Elongate, narrow ; ferruginous or testaceous, the head rufous, the disc of the pronotum in front and the body

beneath black, the last two segments of the abdomen excepted, the elytra with a spot at the end of the

discoidal area, and a faint oblique fascia towards the apex, sometimes extending forwards along the

sutural area, fuscous ; the antenne testaceous, with the apical joint black; the legs testaceous, with the

tarsi black ; the pronotal margins and hood, and the costal margin and median nervure of the elytra to

about the middle, set with very fine scattered hairs. Pronotum with the disc closely punctured and

shining; the carine parallel, the outer ones abbreviated in front and not extending on to the convex

portion of the disc; the hood small, projecting over the base of the head; the membranous margins

rounded and recurved, converging a little in front and rounded behind, with two rows of areole, the

areolz of the outer row large and transversely tetragonal, those of the inner row small. Elytra very

little wider than the pronotum, narrowing a little at the base and rounded at the apex; discoidal and

subcostal areas, and the outer half of the sutural area to beyond the middle, closely reticulated, the rest

of the reticulation wide and subequal; costal area with two rows of mostly tetragonal cells, diminishing

to one at the apex; discoidal area limited within and without by a sharply raised nervure.

extending to a little beyond the apex of the abdomen.

Length 5, breadth 13 millim,

Hab. Panama, Bugaba, Volcan de Chiriqui 3000 feet (Champion).

Found in abundance on the slopes of the Volcan de Chiriqui, in the vicinity of the

coffee-plantations. The hairs on the costa of the elytra are usually missing, but the

minute denticules from which they arise are always to be seen.

Wings long,

2. Macrotingis uniseriata, n. sp. (Tab. II. figg. 9*; 9 a, profile.)

Very like M. biseriata, and similarly coloured, but a little smaller and narrower; the pronotal margins less

dilated, with the outer row of areole much smaller; the costal area of the elytra narrower, with a single

series of tetragonal areole throughout.

Length 43, breadth 17 millim.

Hab. Guatemaua, Capetillo (Champion).

Three examples.

LEPTODICTYA. 238

LEPTODICTYA.

Leptodictya, Stal, Enum. Hemipt. iii. pp. 121, 127 (1878).

In this genus the reticulation of the elytra is close, the subcostal area (costal of

Stal) is very narrow and biseriate, and the costal area has four depressed oblique

transverse nervures or folds. The expanded opaque margins of the pronotum are

formed by two layers of membrane meeting on the outer edge, this being easily seen -

when the insect is viewed sideways *. The rostrum about reaches the end of the

metasternum. The wings do not extend beyond the abdomen.

The Central-American species may be thus tabulated :—

the inner margin forwards; pronotum with the membranous margins

straight, angularly projecting in front ; antenniferous tubercles distinct :

integument pale stramineous . . . . . . +. - . . . « . tabida, H.-S.

Hab. Mexico1?; GuatTEMaLa, Coatepec, Capetillo (Champion).

Four specimens from Guatemala, agreeing well with Herrich-Sehaffer’s figure. This

species was unknown to Stal, who (Enum. Hemipt. iii. p. 134) suggested its affinity

with Leptostyla, Leptopharsa, and Leptodictya. The insect evidently belongs to

Leptodictya, near L. fuscocincta, Stal, from Rio Janeiro. In the present species the

discoidal area of the elytra is very large, extending to beyond the middle, limited

inwards by a sharply raised nervure, from the hinder part of which an oblique

nervure extends forwards. The membranous margins of the pronotum are straight,

converging from the base forwards, and project angularly in front. The elytra, when

closed, are somewhat oval in shape, tapering from the middle. The head has a

small spiniform antenniferous process on either side.

2. Leptodictya cretata, n.sp. (Tab. II. figg. 11; 11a, profile; 114, part of

the body beneath.)

Moderately elongate, rather broad; body black, the integument whitish and partly hyaline; the elytra with

the nervures beyond the middle, and also those along the costal margin thence to the base, fuscous or

brownish ; the interspaces of the pronotum in fresh specimens covered with a bluish-white incrustation,

this colour extending to the discoidal area of the elytra; the antenne testaceous, with the apical joint

in great part black, the first joint and the apex of the third sometimes slightly infuscate; the legs

testaceous, with the tarsi infuscate at the tip. Head with five long slender spines; antenne long and

slender, joint 1 two and a half times as long as 2 and about half the length of 4, 2 very short.

Pronotum with the membranous margins moderately wide and slightly rounded, converging from near

the base to the apex, somewhat flattened, with two or three rows of small opaque areole ; hood rather

short, angularly projecting in front, considerably raised; the three carine feebly foliaceous, the median

carina continuous with the hood, the interspaces closely punctured. LElvtra long, arcuately widened

from the base and broadly rounded at the tip; discoidal area nearly reaching the middle, subfusiform,

very closely reticulated; subcostal area very narrow, minutely biseriate; costal and sutural areas

somewhat closely and subequally reticulated, the reticulation of the costal area abruptly becoming very

much closer on the inner basal half, and on this part similar to that of the discoidal area. Wings extending

to the apex of the abdomen, opalescent.

Length 34-4, breadth 2-24 millim.

Hab. GuatemaLa, Purula in Vera Paz, Panajachel (Champion).

Found in plenty at Panajachel and sparingly at Purula. The Purula specimens are

more or less discoloured and have the antenne black, except at the base. Differs

from all the allied forms in the very unequal reticulation of the costal area of the

elytra, a broad space outside the subcostal area being much more closely reticulated

than the rest.

3. Leptodictya circumcincta, n. sp. (Tab. II. figg. 12; 12a, profile.)

Rather short, broad ; fuscous, the sides of the body beneath, the head, and a small space behind the pronotal

hood, black; the pronotum with the margins, and the elytra with a large oblong space on the inner

part of the costal area about the middle, as well as a few of the minute areole at the base, pale

testaceo-hyaline ; the antennw testaceous, with the basal joint infuscate (the apical joint broken off) ;

the legs testaceous, with the tarsi infuscate. Head with five long spines, and a very short spiniform

antenniferous tubercle on each side; antenne very slender, moderately long, joint 1 about twice as

long as 2, 2 very short. Pronotum with the membranous margins flattened, rather narrow, straight,

converging from the base forwards, with two rows of small opaque areole ; hood rather small, angularly

projecting in front; the three carine feebly foliaceous, the median carina continuous with the hood, the

interspaces closely punctured. Elytra moderately long, broad, arcuately widening to about the middle,

the costal margin thence to near the apex straight, the apex broadly rounded; discoidal area large,

extending to the middle, subfusiform, closely reticulated, limited inwards by a sharply raised nervure ;

subcostal area very narrow, biseriate; costal and sutural areas somewhat closely and subequally

reticulated, the reticulation of the costal area becoming very much closer on the inner part towards

the base.

Length 3, breadth 17 millim.

Hab. Panama, San Feliz in Chiriqui (Champion).

One specimen. Closely allied to LZ. fuscocincta, Stal, from Rio Janeiro (the type

of which is before me); but much smaller and shorter, the pronotal hood larger, the

elytra with an oblong space in the middle only subhyaline, the head with distinct

spiniform antenniferous tubercles.

LEPTOBYRSA. 20

LEPTOBYRSA.

Leptobyrsa, Stal, Enum. Hemipt. iii. pp. 119, 123 (1878).

Stal referred a single species, LZ. steini. from Rio Janeiro, to this genus. His

definition requires modification to include the five others now added, the form of the

discoidal and subcostal (costal of Stal) areas varying according to the species, and

the pronotal hood being sometimes obsolete. The genus chiefly differs from its allies

in having the elytra at least twice as long as the abdomen, broad, more or less widely

reticulated, and strongly rounded at the shoulders, as well as at the apex; the antenne

slender, with long basal joint; the rostral groove uninterrupted, broad on the meso-

and metasternum and closed in front; the rostrum rather short; the head with,

at most, three rather short frontal spines; the posterior portion of the pronotum

abbreviated, and obtuse at the tip; the wings short or obsolete.

The five Central-American species may be thus differentiated :—

Pronotum with the membranous margins slightly rounded, and not constricted

behind.

Elytra very broad, sinuate at the base in front; discoidal area strongly

tumid, the subcostal area very narrow, the costal area with six rows

of areole ; pronotum and elytra pilose; pronotal hood small, transverse. Jatipennis, n. sp.

Elytra narrower, rounded at the base in front; discoidal area angularly

raised, the subcostal area broader, the costal area with five rows of

areole; pronotum and elytra not pubescent; pronotal hood larger . translucida, n. sp.

Pronotum with the membranous margins broadly dilated anteriorly and

constricted behind ; discoidal area of the elytra flat or only slightly raised.

projecting. Head with a rather long frontal spine and two shorter spines below it; antenne long

and moderately slender, joints 1 and 4 subequal in length, 1 about three and a half times as long as 2,

projecting in front to beyond the eyes, recurved and slightly rounded, with small rounded areole—four

rows in front, diminishing to two behind; hood small, transverse; the three carine feebly raised,

the outer ones abbreviated behind and curving outwards, the interspaces dull and punctured; the

triangular posterior portion abbreviated and rounded behind. |Elytra very broad and somewhat

ear-shaped, broadly rounded at the tip, and deeply sinuate in front; discoidal area large, strongly tumid ;

subcostal area very narrow, biseriate ; sutural and costal areas somewhat widely, subequally reticulated,

Hab. Mexico, Cuernavaca (Bilimek, in Mus. Vind. Ces.), Teapa in Tabasco (H. H.

Smith); GuateMaua, Cubilguitz, Teleman, and San Juan in Vera Paz, El Tumbador,

Pantaleon, Capetillo (Champion); Panama, Bugaba, Volcan de Chiriqui, San Lorenzo,

Pefia Blanca (Champion).—Brazit, Rio Janeiro !~4.

The numerous specimens from the above localities differ from Stal’s type of

A. armigera, from Rio Janeiro, in having the marginal spines of the pronotum longer

and more acute; but in a long series there is a good deal of variation in this respect,

the spines varying in number (6-8, the anterior one being sometimes bifid) and length.

The insect also varies a good deal in size (length 3-5 millim.) and colour. The males

are smaller and narrower than the females, and have a narrower transverse fascia on

the elytra. The pronotum and elytral nervures are somewhat thickly clothed with

long, fine, erect hairs. The basal joint of the antenne is sometimes infuscate. The

wings are short. The twelve specimens from Pantaleon are all very small and pallid.

A. abducta, Buch. White, from the Amazons, is an allied form, with the pronotum,

legs, and antenne black. A male from San Juan in Vera Paz and a female from

Chiriqui are figured, both having longer pronotal spines than Stal’s type.

, STENOCYSTA, n. gen.

Rostrum extending to the second ventral suture. MRostral groove parallel, rather narrow, uninterrupted,

closed in front, the sternal and buccal lamine not very prominent. Antenne distant at the base,

moderately long, thickly clothed with long fine projecting hairs; joint 1 stout, nearly twice as long as 2,

2 short and stout, 3 very elongate and slender, thickening a little towards the base, 4 about one-third the

length of 3 and slightly longer than 1 and 2 united, articulated to the preceding on the lower side before

the apex. Head with five short obtuse spines, the one in the middle behind porrect, and obtuse antenni-

ferous tubercles, the eyes transverse and coarsely faceted. Pronotum tricarinate, with broadly dilated,

angular, closely reticulated margins, and a short, compressed, prominent, subangular hood. Elytra broad

oval, extending to far beyond the abdomen, with broadly dilated, closely reticulated margins; discoidal

area large, extending to considerably beyond the middle, elongate-triangular, rounded externally behind ;

subcostal area narrower than the discoidal, the costal area nearly as wide as the two combined; median

nervure sinuous beyond the discoidal area and extending to very near the tip of the elytra. Legs rather

short, moderately stout, the tarsi slender, the knees swollen above. Orifice distinct, surrounded by a

raised carina. ,

STENOCYSTA.—AMBLYSTIRA. 29

In the form of the antenne this genus approaches Megalocysta, but differs from it

in the structure of the pronotum, elytra, &c.

1. Stenocysta pilosa, n. sp. (Tab. II. figg. 18; 18a, profile; 18 d, antenna.)

Moderately elongate, broad; opaque, fuscous, the small areole of the pronotal and elytral margins and of the

pronotal hood hyaline; the elytra with a network of blackish lines on the nervures of the costal and

sutura] areas, and the nervures of the interspaces testaceous, the discoidal and subcostal areas also marked

with black; the antennee fuscous, with the third joint obscure ferruginous beyond the middle and the

apical joint black; the surface thickly pilose, the pilosity extending to the legs, antenne, and elytral

margins, the latter appearing closely ciliate. Pronotum with the angularly dilated margins greatly raised,

converging forwards; hood strongly raised, obliquely truncate and slightly projecting in front; median

carina angularly raised anteriorly, and continuous with the hood, with a few transverse areole, the outer

carine slightly curved inwards in front and terminating in the inconspicuous transverse pronotal calli,

the interspaces on the disc closely punctured ; the triangular posterior portion large and closely reticulated.

Elytra with the areole of the discoidal and subcostal areas, and also those of the greater part of the

sutural area, very small, those of the costal area being larger and more unequal in shape, the subcostal

area quadriseriate, the costal area multiseriate ; discoidal area not raised, flat, well defined.

Length 5, breadth 3 millim. (9.)

Hab. Panama, Bugaba (Champion).

One example. Viewed laterally, the pronotum of this curious insect has four

prominent, angular, foliaceous elevations. The costal area or dilated margin of the

elytra has a marmorate appearance, due to the coloration of the nervures.

AMBLYSTIRA.

Amblystira, Stal, Enum. Hemipt. iii. pp. 120, 129 (1873).

The four Central-American species referred to this genus differ from the type,

A. pallipes, Stal, from Rio Janeiro, in having the triangular posterior portion of the

pronotum less obtuse at the tip, and the head without oblique interocular ridges

(termed spines by Stal in his conspectus of the genera). The buccal lamine are short,

the cavity formed by them being almost open in front. The rostrum about reaches

the meso-metasternal suture. The intercoxal portions of the meso- and metasternum

are very broad, the rostral groove thus being very wide beyond the anterior coxe.

The antenne and legs are slender. The pronotum is faintly carinate at the sides and

uni- or tricarinate on the disc, the median carina being sometimes strongly raised

behind. The form of the costal area is variable, it being in one species (A. levifrons)

confined to the apical portion of the elytra. The discoidal area is rather large in

A, levifrons, smaller.in the other species. The wings nearly reach to the tip of the

elytra. Our four representatives may be thus differentiated :-—

Costal area extending to the base of the elytra; discoidal area rather short, flat. |

Pronotum strongly convex, obsoletely carinate at the sides; costal area

extending narrowly to the base.

Pronotum shining, tricarinate; elytra with a rather large space beyond

the middle, and a streak on the costa near the base, hyaline . . . fuscitarsis, n. sp.

Moderately long, the pronotum shining, the elytra opaque ; black, the elytra with nearly the apical half, and

a narrow space on the costa just below the base, hyaline, the inner nervures on the apical portion black

or fuscous and the others testaceous or yellow ; the antenne flavo-testaceous, with the apical joint in great

part black ; the legs flavo-testaceous, with the apical joint of the tarsi fuscous or black, this colour some-

times extending on to the apices of the tibie. Head rugulose; antenne slender, moderately long,

joints 1 and 2 short, equal, 3 elongate, 4 four times as long as 2. Pronotum transversely convex, rapidly

narrowing forwards and slightly constricted in front; coarsely, closely punctate and tricarinate, the

median carina extending to the apex of the long, triangular, posterior portion and becoming very

prominent behind, the outer carinz short and extending very little beyond the posterior portion. Elytra

narrowing from the middle and rounded at the apex; discoidal area flat, elongate-triangular, not reaching

the middle, the nervures surrounding it not or very slightly raised ; discoidal and subcostal, and part of

the costal and sutural, areas with minute punctiform areole, the rest of the elytra with very large

tetragonal or pentagonal areole ; costal area very narrow to about the middle and not nearly reaching

the apex.

Length 21-23, breadth 1-14 millim. (¢ 9.)

Hab. Guatemata, E] Tumbador, Cerro Zunil, Volcan de Atitlan (Champion); Panama,

Pefia Blanca (Champion).

A, pallipes, Stal, the type of which is before me ; the head without interocular carine ;

the pronotum less constricted in front, with the outer carine short and the triangular

posterior process pointed; the elytra shorter, narrowing from the middle, with the

nervures surrounding the discoidal area scarcely raised and the costal area not reaching

Nine examples, all from the Pacific slope. Differs from A. fuscitarsis in the dull,

unicarinate pronotum, the posterior process of which is more obtuse at the tip and

less strongly carinate, and also in the reticulation of the elytra, the large areole in

the apical third being smaller than in A. fuscitarsis and the other portion closely

reticulated ; moreover, the basal portion of the costa is entirely black. In certain

lights faint traces of the usual outer pronotal carine are to be seen. In one specimen

there are two rows of areole on the hyaline porion of the costa] area.

3. Amblystira atrinervis, n. sp. (Tab. II. fig. 24.

Moderately long, dull, black, when fresh covered with a bluish-white waxy secretion, the elytra with the

areole at the apex and also those in the costal area clear hyaline, the nervures of the latter to far beyond

the middle yellowish-white, those at the apex and in the sutural area black; the antenne with joints 1

and 2 black (the others broken off); the legs flavo-testaceous, with the femora slightly infuscate and the

tarsi black. Head rugulose; antenne with the basal joint longer than the second. Pronotum feebly,

transversely convex, rapidly narrowing forwards and slightly constricted in front; densely, somewhat

coarsely punctate, finely tricarinate, the median carina not reaching the tip of the triangular posterior

Moderately elongate, narrow, shining; black, the pronotum with a small triangular spot in the middle in

front and the apex of the triangular posterior process, and the elytra with the base, a median fascia (not

extending to the sutural area), and the costal area for some distance beyond it, flavous; the antenne

flavous, with the apical joint black, except at the base; the legs flavous, with the tarsi fuscous. Head

smooth; antenne moderately long, slender, joints 1 and 2 equal. Pronotum transversely convex,

the abdomen ; the discoidal area elongate-triangular, not reaching the middle, limited externally by a

straight raised nervure and inwardly by an oblique one, aud partly open behind; the costal and subcostal

areas very narrow, about equal in width, the costal area with a single row of smali areole. Wings

extending to beyond the abdomen.

Length 4, breadth 1 millim.

Hab. Mexico, Vera Cruz (H. H. Smith).

Three specimens. Very like 7. precellens, Stal, from Rio Janeiro, the type of

which is before me, but differing from it in having much smaller areole along the costal

margin of the elytra, the costal area itself being very narrow and the discoidal area

less distinctly margined behind. The basal joint of the antenne is also rather less

elongate, the eyes are more prominent, the general coloration is less uniform, and the

insect itself is a little smaller and narrower.

2. Tigava convexicollis, n. sp. (Tab. IL. figg. 29; 29a, part of the body

beneath.)

Head black, the decumbent lateral spines and the buccal lamine flavous; the pronotum ferruginous or flavo-

ferruginous, with the transverse calli black, the anterior margin flavous; the elytra testaceous, with a

mark on the discoidal area, and a \-shaped patch beyond it, extending to the costal and inner margins,

and partly enclosing a subtriangular pallid or ochreous space, smoky or black; the antenne testaceous, with

partly open behind ; the costal and subcostal areas very narrow, the costal area with a single row of

small, oblong areole.

Length nearly 4, breadth 1 millim.

Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion).

Four examples. Differs from 7. precellens and T. pulchella in the feebly and

incompletely margined pronotum, the outer carine of which are also much less distinct.

DICHOCYSTA, n. gen.

Rostrum reaching the end of the metasternum. Rostral groove parallel, uninterrupted, closed in front.

Antenne somewhat distant at the base, joints 1 and 2 very short, stout, 3 elongate and more slender,

slightly tapering outwards, truncate at the tip, 4 lanceolate. Head with five rather long decumbent

spines, the lower two approximating at the tip, and short, obtuse antenniferous tubercles. Pronotum

tricarinate, with a very large erect bulbiform process arising from the margin on either side, the two

processes covering the greater portion of the disc and closed within by a foliaceous expansion of the outer

discoidal caring, the triangular posterior portion long. Elytra extending to beyond the abdomen, some-

what oval, rounded at the tip; discvidal area very large, elongate-triangular, extending to beyond the

middle; subcostal and costal areas very narrow, the latter constricted at one-fourth from the apex, and

with a single series of long subhyaline areole. Orifice prominent, surrounded by a raised carina. Wings

The remarkable Central-American insect from which the above characters are taken

is perhaps nearest allied to Zeleonemia; from which it differs in having the antenne

more distant at the base, with the third joint smoother and more slender, the legs

stouter, and the pronotum furnished with a very large bulbiform process on each

side. The closing of the latter by the foliaceous outer discoidal carina is best seen

in immature examples. Monanthia fasciata, Fieb., and Tingis globulifera, Walk.,

both from India, have a somewhat similarly formed pronotum.

1. Dichocysta pictipes, n. sp. (Tab. III. figg. 1; la, profile; 16, part of the

body beneath ; 2, var.)

ferrugineo-testaceous, mottled with fuscous. Antenne moderately elongate, joint 2 slightly shorter than

1, 3 about three times as long as 4. Pronotum with the short anterior portion parallel, the anterior

margin rounded at the middle and slightly produced, the posterior portion closely reticulated, the median

first two joints short, the third elongate, cylindrical, and obliquely truncate at the tip,

and the fourth moderately long, more or less lanceolate or oval; the pronotum is

tricarinate and margined, with or without a hood ; the discoidal area extends to beyond

the middle of the elytra; the subcostal and costal areas in the typical species are

exceedingly narrow and uniseriate, sometimes wider and with more numerous areole ;

the elytra extend to far, and the wings to a little, beyond the abdomen; the rostrum

subangularly projecting in front, the marginal carine moderately prominent, the interspaces rugulose

and finely punctured, reticulate behind. Elytra moderately long, gradually widening in their basal third,

and constricted beyond the middle, the apices broadly rounded, the outer longitudinal nervures stout and

cariniform ; discoidal area with deeply impressed areole; subcostal and costal areas exceedingly narrow,

uniseriate, the latter with very narrow, long areole. Rostral groove gradually widening beyond the

anterior coxe, the rostrum extending to beyond tke first ventral suture.

Length 53, breadth 12 millim. (<¢.)

Hab. Panama, Volcan de Chiriqui (Champion).

One example. Recognizable by its uniform brownish-ochraceous colour, very long

rostrum, and gradually widened rostral groove. The very long rostrum brings the

species into Stal’s subgenus Amaurosterphus, but the pronotum has not a subglobose

hood in front.

2. Teleonemia forticornis, n. sp. (Tab. III. fig. 5.)

Elongate, narrow, opaque; blackish-fuscous, the spines on the head, the pronotal carine, the apex of the

pronotal process, and the elytra pale brown ; the latter with a black submarginal streak at the middle

extending forwards, the apex broadly fuscous, and the intervening costal areolw hyaline; the antenn

black, the legs ferruginous, with the tarsi darker. Head with an obtuse frontal spine; antenne very

stout and elongate, about as long as the elytra, shortly pilose, Joints 1 and 2 equal, 4 much longer than

1 and 2 united. Pronotum tricarinate, the two outer carine converging in front and behind, and with a

compressed hood in front, which projects angularly over the base of the head, the marginal carine

becoming feeble behind, the interspaces coarsely, shallowly punctate. Elytra moderately long, very

gradually widening in their basal half, slightly constricted beyond the middle, and broadly rounded at the

apex, the outer longitudinal nervures stout and cariniform ; discoidal area widely reticulated ; subcostal

area rather broad, biseriate; costal area exceedingly narrow to the middle and then widened, with

tetragonal moderately large areole at this part, the areole becoming very narrow forwards. Rostral

groove narrow, subparallel, the rostrum nearly reaching the end of the metasternum.

Length 43, breadth 13 millim. (¢.)

Hab. Panama, Bugaba (Champion).

One specimen. In the form of the antenne this insect approaches the Colombian

T. validicornis, St&l, the type (¢) of which is before me; but the present species is

not nearly so elongate, the antenne are shorter, the pronotum has a compressed hood

in front, and the reticulation of the basal half of the elytra is much wider and more

uniform. The hairs on the antenne are extremely short.

7. forticornis belongs to Stal’s subgenus Amaurosterphus, but it has the rostrum

shorter than in his 7. morio, from Rio Janeiro (the type of which is before me), the

costal area of the elytra broader behind, the antenne much stouter, &c.

8. Teleonemia rugosa, n. sp. (Tab. III. fig. 4.)

Elongate, slightly shining; fuscous or blackish, the pronotum sometimes reddish, the elytra darker towards

the tip, the spines on the head and the middle of the pronotum in front testaceous; the costal area for

some distance before the apex, and sometimes some of the areol along the apical margin, hyaline; the

antenne black or obscure ferruginous, the legs obscure fuscous or ferruginous. Head with a slender

decumbent frontal spine; antenne stout, about three-fourths the length of the elytra, joint 2 slightly

shorter than 1, 3 nearly three and a half times the length of 4, 4 a little longer than 1 and 2 united.

Pronotum feebly tricarinate, the median carina sharply raised anteriorly and slightly projecting in front,

the marginal carine feeble and scarcely visible from above, except in front; the interspaces very coarsely,

rugosely punctured, reticulate behind, the calli prominent. Elytra moderately elongate, widening to

about the middle, more or less constricted towards the apex, with the apices broad and somewhat obtuse ;

discoidal area with deeply impressed areole ; subcostal and costal areas very narrow, the uniseriate

areole of the costal area very small to beyond the middle, becoming larger towards the apex, the subcostal

area irregularly biseriate behind. Intercoxal portion of the metasternum oval, the rostral groove

narrower on the mesosternum, the rostrum extending to the meso-metasternal suture. Legs rather

stout.

Length 43-44, breadth 14-13 millim.

Hab. GuatemMaLa, Panzos and Zapote (Champion); Panama, Volcan de Chiriqui

Five specimens. Distinguishable by the coarsely, rugosely punctured, feebly carinate

pronotum, the median carina only being prominent in front, the moderately stout

antenne, and the medially dilated elytra.

An example from Panzos is figured.

4. Teleonemia pilicornis, n. sp. (Tab. III. fig. 6.)

‘Elongate, narrow, subparallel, opaque, blackish-fuscous; the elytra with a submarginal black streak extending

from the middle forwards, the costal areole from the middle to near the apex (the third from the end

excepted) and also those towards the base, yellowish-hyaline, the areole along the apical margin also

pale; the antenne fusco-ferruginovs, with the apical joint black; the legs ferruginous, with the tarsi

black; the head, pronotum, and under surface clothed with a mealy pubescence. Head with a very

and behind, the median carina subangularly projecting in front, the marginal carine moderately prominent,

the interspaces rugulose and finely punctured, reticulate behind. Elytra elongate, constricted beyond the

middle, and distinctly dilated at the apex, the apices broadly and bluntly rounded ; discoidal area with

deeply impressed areole; subcostal area narrow, biseriate ; costal area narrow, uniseriate, the areola

oblong. Rostral groove rather wide and subparallel beyond the anterior coxe, the rostrum extending to

the meso-metasternal suture.

Length 4, breadth 13 millim. (¢.)

Hab. Guatemata, Zapote (Champion).

One example. Differs from 7. prolixa and other allied Central-American species in

the densely, distinctly pilose antenne, the pilosity being especially noticeable on the

third joint. In other respects the insect is very like 7. prolixa, except that the

antenne are stouter, the outer pronotai carine are more curved, the subcostal area of

the elytra is biseriate, and the series of hyaline areole on the costal area is interrupted

behind.

Very elongate, narrow, widening a little behind, opaque; black, the constricted anterior portion of the

pronotum ferruginous in the middle and flavous at the sides, the marginal carinw of the pronotum, the

costal margin of the elytra to beyond the middle, and the apices of the tibie obscure ferruginous; the

head, the pronotum in front, and the body beneath with a whitish mealy pubescence. Head with a

short, stout, obtuse frontal spine ; antenne moderately stout, about two-thirds the length of the elytra,

constricted anterior portion relatively long and subparallel, the anterior margin almost straight ;

tricarinate, the marginal carine not prominent, the interspaces coarsely, rugosely punctured. Elytra

flat, very long and narrow, widening behind, the costal margin slightly hollowed beyond the middle, the

apices broadly rounded ; discoidal area with very deeply impressed punctiform areole ; subcostal and

costal areas exceedingly narrow, uniseriate, the areole of the costal area long and narrow, and scarcely

visible from above. Rostral groove narrow, parallel, the rostrum extending to the meso-metasternal

suture.

Length 5, breadth 13 millim.,

Hab. Panama, Bugaba (Champton).

One female example. Very like 7. aterrima, Stal, the type of which, from Bogota

(and a second specimen from the Amazons, in the Oxford Museum), is before me; but

differing from that species in its much narrower shape, the narrower intercoxal portion

of the metasternum, the rugosely punctured pronotum, the anterior margin of which is

not produced in the middle (as in 7’. aterrima), and the relatively shorter apical joint

of the antenne. In 7. aterrima the apical joint of the antenne is about half the

length of the third, the third being as long as in the present species.

6. Teleonemia bifasciata, n. sp. (Tab. III. figg. 8; 8 a, profile.)

Moderately elongate, dull, fuscous or brownish-ochraceous, darker beneath ; the elytra with a more or less

distinct irregular transverse fascia before the middle (occupying about half the discoidal area) and another

before the apex infuscate or black, the base (including the pronotal process), a space at the sides beyond

the middle, and some of the areole at the tip, yellowish or pale testaceous; the antenne fuscous or

obscure testaceous, with the apical joint black; the legs testaceous, with the tarsi infuscate; the pronotum

spine rather stout and semierect ; antennz moderately stout, extending to a little beyond the base of the

elytra, joints 1 and 2 equal, 4 longer than 1 and 2 united. Pronotum sharply tricarinate, the marginal

carine also prominent, the anterior margin subangularly projecting in the middle in front, the interspaces

rugulose and finely punctured, reticulate behind. Elytra moderately long, constricted behind the middle,

and rounded at the apex, the outer longitudinal nervures stout and cariniform; discoidal area with deeply

impressed areole ; subcostal and costal areas very narrow, uniseriate, the costal area with small oblong

areole, which are distinct to the base, those between the two transverse fascie being hyaline. Rostral

groove wide and subparallel behind the anterior coxe, the rostrum extending to the meso-metasternal

suture.

Length 4-47, breadth 1} millim.

Hab. Guatemata, Chiacam in Vera Paz (Champion); Panama, Bugaba (Champion).

Three examples. Differs from 7. notata, &c., in the prominent, semierect, rather

stout frontal spine and the irregularly bifasciate elytra. A closely allied form (included

by Uhler under 7’. sacchari) occurs in the Island of Grenada.

sometimes with the carine and the triangular posterior portion flavous, the discoidal and sutural areas of

the elytra streaked with fuscous or black in light-coloured specimens, the legs and the three basal joints

of the antenne sometimes ferruginous or testaceous; the elytra subparallel, or a little widened at the

A very variable species. The type, a male, of 7. prolixa, from Rio Janeiro, is before

me, and it is more parallel than most of our specimens, and has the very narrow costal

area of the elytra pale from the base to near the apex. In the Central-American

costal area is sometimes blackish or fuscous, with a short space only beyond the middle

flavous or hyaline. The insect varies from 33-5 millim. in length and from 1-12 millim.

in breadth. TZ. proliza (t= elevata, Fabr.) is very like the 7. sacchari of Herrich-

Schaffer, Fieber, and Stal (? of Fabricius), from the Antilles *, and the locality ‘“‘ Mexico,”

amongst others quoted by them for the last-mentioned insect, probably refers to the

present species; T. prolixa, however, has smaller and very much less elongate areole

in the costal area of the elytra, the areole, too, in Z. sacchari being separated by

blackish or fuscous transverse nervures. The var. 8 may prove to be distinct. We

figure a typical example from Bugaba and a macropterous specimen of the var. 8 from

Cerro Zunil.

8. Teleonemia notata, n. sp. (Tab. III. figg. 11; 11 a, profile; 11 4, antenna.)

Moderately elongate, narrow, narrowing a little behind, opaque; ferruginous or brown, darker beneath, the

triangular posterior portion of the pronotum, and sometimes the carine also, more or less yellowish, the

elytra pale brown, streaked with fuscous or black, the markings tending to form a dark patch before

the apex, the apical areole more or less pale, the narrow costal area flavous to near the tip; the antenne

obscure ferruginous, with the apical joint darker; the legs obscure testaceous or ferruginous, with the

tarsi darker; the pronotum and under surface clothed with a mealy pubescence. Head with short

frontal spines; antenne comparatively short, about reaching the base of the elytra, moderately stout,

joints 1 and 2 equal, 4 oblong-ovate, not or scarcely longer than 1 and 2 united. Pronotum tricarinate,

the median carina subangularly projecting in front, the marginal carine rather prominent, the interspaces

rugulose and finely punctured, reticulated behind. LElytra moderately long, slightly narrowing behind,

feebly constricted beyond the middle, and rounded at the apex; discoidal area with the areole rather

deeply impressed ; subcostal and costal areas exceedingly narrow, uniseriate, the areole oblong and very

narrow. Rostral groove rather wide and parallel behind the anterior coxe, becoming still wider on the

metasternum, the rostrum extending to the meso-metasternal suture.

Numerous examples. Very like 7. prolixa, var. 6, but differing from it in the

relatively shorter antenne, with the apical joint shorter, stouter, and more oval in

shape, it being about equal in length to the first and second joints united. We figure

an example from Bugaba.

This is one of the commonest species of the genus within our limits. It may be

known by the very shallowly impressed areole of the discoidal area of the elytra, this

part being finely pubescent, like the pronotum and under surface. The uniseriate

costal area is comparatively wide throughout, the transverse nervures separating the

hyaline areole being sometimes infuscate. ‘The antenne (broken off in the type before

me)are stout, moderately long,and shortly pilose. The general colour is grey or brownish,

with darker markings on the elytra, there being always a pale transverse fascia before the

apex. The rostral groove is gradually widened behind the anterior coxe. The principal

characters of 7. scrupulosa—the shortly pilose antenne and the finely pubescent dis-

coidal area-—-were not mentioned by Stal. A specimen from Orizaba is figured.

10. Teleonemia nigrina, n. sp. (Tab. III. figg. 13; 13 a, antenna; 13 6, the

body beneath, showing the abdominal tubercles, 9 .)

elytra mottled with black and with the long narrow areole of the costal area hyaline, separated by trans-

verse black nervures, the tip of the pronotal process and a small space near the apex of the elytra, as

well as the base of the discoidal area, more or less pale; the antennx and legs black or fuscous, the tibiee

partly flavous or ferruginous ; the body beneath and the pronotum clothed with a close mealy pubescence.

Head with a short, stout, rather prominent frontal spine ; antenne very shortly pilose, exceedingly stout,

short, about reaching the base of the elytra, joints 1 and 2 equal, 3 not twice the length of 4, the latter-

ovate and of the length of 1 and 2 united. Pronotum subtruncate in front, rather sharply tricarinate,

the outer carine slightly sinuous, each, the marginal ones included, with a row of small areole, the

interspaces rugulose and finely punctured, the posterior portion reticulated. Elytra moderately long,

slightly narrowed and constricted beyond the middle, with the apices bluntly rounded; discoidal area

with deep punctiform areole ; subcostal area narrow, biseriate; costal area narrow, uniseriate, the areole

the type of the genus, in having the costal margin of the elytra concave from about

the basal third (instead of rounded), and the costal area very unequally reticulated, the

hyaline areole on the inner part forming two well-defined patches.

ATHEAS.

Rostrum short, not extending beyond the anterior coxe. Rostral groove uninterrupted, closed in front; the

intercoxal portion of the metasternum cordate, the mesosternai lamin parallel or converging at the

middle. Antenne slender, the two basal joints stouter, the first joint much longer than the second.

Head short, with more or less acute antenniferous tubercles and an obtuse tubercle in the centre in front,

the usual spines obsolete. Pronotum without hood, tricarinate, with expanded, thin, membranous,

uniserlate margins, the triangular posterior portion sometimes abbreviated and obtuse at the tip. Elytra

extending to far beyond the abdomen, oblong oval or subparallel, rounded at the tip; subcostal and

discoidal areas very closely reticulated, the latter extending at least to the middle and rounded within ;

costal area broad or moderately broad, hyaline, with two or three rows of areole. Wings nearly as long

as the elytra. Orifice distinct. Legs slender. Form oblong, very depressed.

The three small species referred to this genus are closely allied. The unusually

short rostrum, the complete absence of the usual spines on the head, the simply

carinate pronotum, and the prominence of the antenniferous tubercles, &c. separate

them from Leptostyla and Leptodictya; and the thin, membranous margins of the

pronotum and elytra, the acute antenniferous tubercles, &c., from Monanthia. The

three species may be separated thus :—

Antenniferous tubercles slender andacute . . . .. .. . . . . . flavipes, n. sp.

Antenniferous tubercles shorter and stouter.

Pronotum feebly tricarinate ; mesosternal lamine parallel . . . . . . fuscipes, n. sp.

Pronotum sharply tricarinate; mesosternal lamine converging at the

middle 2. 2... we ee ee ee nigricornis, D. Sp.

Thirteen specimens. Differs from the following species in the longer and more acute

antenniferous tubercles, the longer and more slender antenne, the broader membranous

margins of the pronotum, and the wider reticulation of the costal and sutural areas of

the elytra. In immature examples the pronotum and elytra are fuscous. The antenne

beyond the base of the elytra, moderately slender, joint 1 nearly twice as long as 2, 3 about twice as long

as 4, 4 a little longer than 1 and 2 united. Pronotum feebly tricarinate, the outer carine indistinct at

the middle, closely punctured ; the membranous margins narrow, straight, and converging forwards,

rounded behind, with a row of small areole. Elytra long, slightly rounded at the sides; discoidal

area extending to beyond the middle; subcostal area bi- or triseriate; costal area biseriate, in some

specimens ( ? ) triseriate in the widest part. Mesosternal lamin parallel.

Length 24-23, breadth 4-1 millim. (¢ 9.)

Hab. Mexico, Cordova (Bilimek, in Mus. Vind. Ces.), Teapa in Tabasco (H. H. Smith) ;

GUATEMALA, Chiacam and San Gerénimo in Vera Paz, Rio Naranjo (Champion).

Fourteen specimens, two only of which are from Mexico. Differs from the following,

A. nigricornis, in the more feebly carinate pronotum, the slightly longer antenne, the

parallel mesosternal lamine, and darker legs. ‘The costal area is sometimes triseriate in

the widest part in the females. An example from Rio Naranjo is figured.

3. Atheas nigricornis, n. sp. (Tab. III. fig. 21.) _

Very narrow, black, the pronotal carine whitish, the elytra and the triangular posterior portion of the

pronotum varying in colour from fuscous to pale testaceous, the membranous margins of the pronotum

Pronotum distinctly tricarinate, closely punctured; the membranous margins narrow, straight, and

converging forwards, rounded behind, with a row of small areole. LElytra long, narrow, very feebly

widening to about the basal third; discoidal area extending to beyond the middle; subcostal and costal

areas biseriate. Mesosternal laminew converging at the middle, the rostral groove very narrow at

this part. .

Length 23, breadth 1 millim. (¢ 9.)

Hab. Mexico, Orizaba (Bilimek, in Mus. Vind. Ces.); GuateMaua, Cerro Zunil,

Panajachel, Zapote, Capetillo, Guatemala city, Aceituno (Champion).

Numerous examples from Guatemala, four only from Mexico. A specimen from

Cerro Zunil is figured.

ACYSTA, n. gen.

Rostrum extending to the meso-metasternal suture. Rostral groove uninterrupted, closed in front, gradually

widening behind the anterior coxw, the intercoxal portion of the metasternum transverse. Antennee

slender, the two basal joints included, the basal joint about twice as long as the second. Head short, with

two short converging spines in front and a decumbent spine on either side. Pronotum without hood,

tricarinate, with narrow, thin, membranous margins, sometimes obliterated at the middle, the triangular

posterior portion acute at the tip. Elytra at least one and a half times the length of the abdomen, oval,

short and surrounded by raised nervures, the outer (median) nervure prominent to near the tip;

costal area broad, hyaline, with three or four rows of areole. Orifice distinct. Wings short. Legs

slender.

The two small species from which these characters are taken cannot be satisfactorily

included in any of the genera tabulated by Stal. A third species, represented by a_

single mutilated specimen (without head) from Chacoj in Vera Paz, perhaps belongs

here ; it differs from the others in having the marginal carine of the pronotum still

narrower and the costal area biseriate.

1. Acysta integra, n.sp. (Tab. III. fig. 22.)

Moderately long, ferruginous, the head and the body beneath black ; the pronotum with the margins and about

half the triangular posterior portion pale testaceous, the areole of the margins hyaline ; the elytra with a

broad transverse fascia on the costal area before the middle, another near the apex, and the apical half

of the discoidal area, more or less fuscous, the rest of the costal area pale testaceous and hyaline, the

basal half of the discoidal area also pale, the nervures of the sutural area brownish; the spines on the

head and the antenne flavo-testaceous; the legs testaceous. Antenne moderately long, joint 3 twice as

long as 4. Pronotum short, broad behind, constricted in front; closely punctured and tricarinate, the

outer carins almost obsolete on the disc; the membranous margins entire, rather narrow, rounded behind,

carina in front, and the triangular posterior portion whitish or pale testaceous ; the elytra with a trans-

verse fascia below the base, extending to the subcostal and discoidal areas, the apex, and sutural area

fuscous, the rest of the costal area pale testaceous or whitish, with the areole hyaline, the raised longi-

tudinal nervures testaceous ; the spines on the head, the antenna, and legs flavous. Antenne moderately

A common insect from Guatemala southwards, occurring on both the Atlantic and

Pacific slopes. St&l’s type has been examined. In this, as in the following species,

the intercoxal portion of the metasternum is transversely cordate, and the rostral

channel rather wide and subparallel on the mesosternum, the rostrum reaching the

meso-metasternal suture. The wings are nearly as long as. the elytra. The North-

American WM. labeculata, Uhler, is probably an allied form. A specimen of Jf. mono-

tropidia from Chacoj is figured.

2. Monanthia c-nigrum, n. sp. (Tab. III. fig. 25.)

Finely pubescent, black, the elytra and the disc of the pronotum obscure ferruginous, the membranous

margins of the pronotum ochraceous, the elytra with the posterior portion of the nervure closing the

discoidal area black (forming a C-shaped mark) and the nervures of the sutural area in great part also

black, the areole of the costal area hyaline; the antenne with joint 3 testaceous and the other joints

black ; the femora and tarsi black, the tibiee testaceous. Head with three short frontal spines; antenne

rather short, joints 1 and 2 equal, 4 about as long as 1 and 2 united. Pronotum with the opaque mem-

branous margins extending rather broadly inwards, in some specimens occupying about two-fifths of the

entire width; the disc closely punctured and tricarinate, the outer carine short. Elytra oval; the

discoidal and subcostal areas closely punctured, the discoidal area extending to the middle, the nervures

surrounding it very prominent, the outer one abruptly curved behind; the costal area with a single

row of large areole; the sutural area unequally reticulated.

Length 24-3, breadth 1-14 millim.

Hab. Mexico, Atoyac (H. H. Smith), Orizaba (Bilimek, in Mus. Vind. Ces. ;

H. H. Smith); Guatemaua, Zapote (Champion); Nicaragua, Chontales (Janson).

Fourteen examples. Very like M. monotropidia, but with the membranous margins

of the pronotum broader and extending inwards, the median nervure of the elytra more

abruptly curved behind and also more prominent, usually with a short branch extending

obliquely inwards at the point of curvature. WM. loricata, Dist., from Entre Rios, is

another closely allied species ; but it differs from M/. c-nigrum in having the elytra longer,

with the areole of the costal area very unequal in size, and the triangular posterior

portion of the pronotum and the discoidal area of the elytra rather widely reticulated.

One of the specimens from Orizaba is of a pale ochraceous colour, due to immaturity.

An example from Atoyac is figured.

An additional species of Tingitide has been sent to me for examination from the

Vienna Museum since the preceding pages were in type ; it is as follows :—

LEPTOSTYLA.

9 (a). Leptostyla partita, n.sp. (Tab. IIT. fig. 26.)

Elongate, narrow, widening behind; body black, the integument whitish and hyaline; the elytra with a.

small spot on the discoidal area, a curved oblique fascia extending from the inner part of the sutural area

to the costal margin near the tip, and the nervures beyond it fuscous, the other nervures pale testaceous ;

the antenne testaceous, the basal joint and the apical half of the fourth joint black ; the legs testaceous.

Head with three slender prominent spines; antenne elongate, slender, joint 1 about two and a half

times as long as 2, 3 about three times the length of 4. Pronotum with moderately wide, raised,

membranous margins, gradually converging forwards, with the anterior and hind angles rounded, the

areole small and in two rows; hood short and small, considerably raised, projecting slightly in front ;

the outer carine feebly, the median carina more strongly, foliaceous, the interspaces closely punctured ;.

the triangular posterior portion membranous and closely reticulated. Elytra twice as long as the

abdomen, constricted at the middle and widening beyond, the apices rounded; discoidal area narrow, not.

reaching the middle, closely, reticulated ; subcostal area very narrow, biseriate ; costal area with two rows

of rather large pentagonal areole at the middle, diminishing to one at the base and apex; sutural area

very unequally reticulated, the areole becoming very large at the apex. Rostrum reaching the meso-

metasternal suture.

Length 23, breadth (of the elytra near the tip) 1 millim.

Hab. Mexico, Pedregal (Bilimek, in Mus. Vind. Ces.).

One example. Closely allied to Z. gracilenta, from Guatemala, from which it

differs in having the elytra much longer and narrower, and more constricted at the

middle, with the costal area not so wide and uniseriate only at the base, and the apical

joint of the antennz partly testaceous. From the North-American L. oblonga (Say) it

may be separated by the narrower and longer elytra, with the areole of the costa] area

much less elongate.

PHYMATA. 49

Fam. PHYMATIDA.

Herr A. Handlirsch’s Monograph of this family is now in the press. He has

examined specimens of all the Central-American species represented in our collection,

and I have endeavoured to follow him wherever possible, the references to his work

being taken from proof-sheets kindly forwarded. Two genera only are certainly

represented within our limits, Phymata and Macrocephalus; a third, Agreuocoris, is

recorded by Herr Handlirsch as from “ Mexico,” but, as he says, the insect is probably

of eastern origin. One Phymata and seven Macrocephali are here described as new,

the whole of these being unknown to him.

The more important synonymy only of the Central-American species is mentioned

below, it being given at length by Herr Handlirsch. |

These insects, as noted by Prof. Uhler and other writers regarding Phymata erosa, L.

= fasciata, Gray), bury themselves in the pollen of various flowers, and are thus

easily enabled, by means of their raptorial front legs, to catch the small insects that

come within reach, their habits being similar in this respect to those of many Mantide.

They have been noticed to attack small Hymenoptera, Coleoptera, and Lepidoptera, as

well as the larve of Tenthredinide, Aphides, &c.

I follow Herr Handlirsch in placing most of the Central-American Phymate under

one variable, abundant, widely distributed species, P. erosa (J.inn.) (fasctata, Gray).

The five other Central-American members of the genus appear to be much less

variable ; they are all comparatively rare, one only of them, P. acutangula, Guér.,

having been found in any numbers. Our species may be separated thus :—

a. Abdomen angularly or acutely dilated at the sides ; head short or moderately

long.

a’. Pronotum constricted at the sides between the anterior and posterior

lobes, with the lobes also more or less emarginate; legs not annulate . erosa, L.

Herr Hirdlirsch in his Monograph recognizes fifteen forms or subspecies of this

abundant and very variable American insect, five only of which are found within our

South America or the Antilles. The five inhabiting our region are as follows :—

Vera Paz, Quezaltenango, Capetillo, Duefias (Champion); Nicaragua, Chontales

(Janson) ; Panama, Volcan de Chiriqui (Champion).

This is the commonest form of the species in Central America. It has the sides of

the posterior lobe of the pronotum strongly foliaceous and raised, and produced into

three acute teeth, the intermediate one being the longest and directed forwards; and

the pronotal margins more or less granulate. Many of the males from Yucatan and

Vera Paz have the entire pronotum nigro-fuscous and the transverse fascia on the

abdomen black. The var. fasciata has been found in plenty in Yucatan, as well as in

Chiriqui and elsewhere. A male from Capetillo and a female from Temax are figured.

* Wrongly numbered at the bottom of the Plate.

PHYMATA, 51

Prof. Uhler remarks [Proc. Calif. Acad. Sci. (2) iv. p. 282] that “ P. fasciata is now

distributed over the greater part of North America, and that it has doubtless been

distributed by hurricanes and less violent storms of wind from region to region, and

through the distribution of garden plants by commerce it has unquestionably been

transported to distant localities.” Also that “it may be expected to occur wherever

roses and herbaceous garden plants are carried from North America.”

Var. granulosa. (Tab. IV. fig. 3, ¢.)

(Schumann), Rincon in Guerrero (H. H. Smith), Orizaba “4 (H. H. Smith and F. D. G.),

Jalapa (Hoge); Guatemaa, San Gerénimo (Champion); Costa Rica, Caché (Rogers).

In this variety the surface is distinctly granulate, and the lateral angles of the

pronotum are moderately dilated, the intermediate tooth obtuse or not very prominent.

The males usually have the base or sides of the posterior portion of the pronotum, and

the transverse fascia on the abdomen, blackish or fuscous. This form appears to be

confined to Central America. It has been found in plenty at Orizaba and San

Gerdnimo. A male from San Gerénimo is figured.

Zapote, Capetillo (Champion), Guatemala city (Salvin); Panama », Bugaba, Volcan de

Chiriqui (Champion).

This is a small form, with the connexivum usually more or less spotted with black

or fuscous before and behind the dark transverse fascia, the males being sometimes

(the females rarely) very prettily marked. It is perhaps confined to Central America.

It has been found not uncommonly at Chilpancingo, Capetillo, and Bugaba. A male

from Bugaba is figured.

This is another small form, some of the males measuring 5 millim. only in length,

chiefly differing from the var. severini in the shorter head, with obtuse frontal process,

and the less acute outer hind angles of the segments 1-3 of the connexivum. The

abdomen has the usual transverse dark fascia, and, rarely, in the males, a few spots in

addition. ‘The insect is widely distributed in Central and South America. About

thirty specimens have been seen, a good many of which are from Chiriqui. A male

from Belize is figured.

This form resembles the var. parva, but it is larger and usually has the legs more or

less suffused witi: reddish (possibly due to discoloration after death). The Yucatan

specimens (¢ @ ), named by Herr Handlirsch, have an additional dark transverse fascia

in front of the usual one, and the abdomen more broadly and less angularly dilated

than usual. I have seen the types of Mayr and Stal. ‘The locality “ Georgia” given

by Mayr 1" is stated by Handlirsch !9 to be probably incorrect.

the clavus and corium fuscous, with whitish dots, the abdomen with a broad transverse blackish fascia,

occupying the fourth segment and the basal half of the fifth, the membrane smoky ; the antenne ochraceous,

with the apical joint fuscous ; the legs ochraceous, the anterior femora and coxe partly fuscous, the four

hinder femora and tibie faintly annulated with fuscous. Head moderately long, the anterior process rather

prominent, with the lateral lobes obtuse at the tip; granulate, and with two prominent subangular

tubercles on the disc behind the eyes; antenne rather slender, joint 3 longer than 2, and 4 a little

longer than 3. Pronotum strongly, subequally trisinuate at the sides, the anterior angles prominent

but obtuse, the four marginal teeth subequal; anterior lobe finely granulated, the posterior lobe coarsely,

shallowly, confluently punctured ; the dorsal carine prominent; the base feebly emarginate in the middle.

Scutellum carinate and granulate. Corium and clavus minutely punctured. Connexivum sparsely

granulate, almost parallel in front, gradually widening to the subacute apex of the fourth segment, and

obliquely narrowing thence to the broadly rounded apex, the outer apical angles of segments 1-3 slightly

thickened.

One example. Differs from all the other Central-American species of the genus in

the strongly trisinuate sides of the pronotum, the four teeth thus formed being about

equally prominent. In the annulate legs it approaches P. annulipes and P. noualhieri,

but differs from both in the much less widened connexivum. The insect is unknown

to Herr Handlirsch, after whom I have much pleasure in naming it.

Numerous examples of this species have been found in Chiriqui, two only in Tabasco,

these latter having the frontal process more obtuse at the tip. Lasily distinguishable

from the other Central-American species by the long head, the acute lateral angles of

the pronotum, the strongly and acutely dilated abdomen, the fourth segment of which

is produced laterally into a long, acute tooth, and comparatively small size. ‘The

eighteen specimens obtained show very little variation in colour. I have not seen

it from Guatemala. An example from Bugaba is figured.

Hab. Mexico (coll. Signoret 173, in Mus. Vind. Ces.: ¢ ).

Easily distinguishable from the allied forms with the abdomen parallel at the base

by the exceedingly elongate apical joint of- the antenne in the male. The head has

two prominent conical tubercles on the disc and a bilobed frontal process. The

anterior tooth of the lateral angles of the pronotum is subvertical and conical in shape.

The connexivum is broadly and abruptly dilated beyond the middle, and obliquely

narrowed thence to the apex; the segments 1-3 have each a conspicuous tuberculiform

prominence at the outer apical angle (a character not mentioned by Stal), the first

segment being also thickened and dilated at the outer anterior angle; the fourth

segment is strongly foliaceous, with two prominent teeth, the outer apical angle also

being produced into a tooth; the fifth segment is dilated at each outer angle. The

type has been forwarded to me by Herr Handlirsch for examination. The locality

‘““ Mexico” seems to require confirmation. |

Hab. Nortu America, Pennsylvania 1, Georgia !.—Mexico, Chilpancingo in Guerrero !

Of this species we possess four specimens from Guatemala and one from Mexico,

three of which have been examined by Herr Handlirsch. It is very like P. annulipes,

but has a much shorter apical joint to the antenne in the male (as long as 2 and 3

united in the present species, about three and a half times as long as 3, or longer than

the three others united, in P. annulipes), and the outer apical angles of the first three

segments of the connexivum less prominent. The pronotum varies in colour, it being

almost entirely black in one of the specimens. ‘The head has a subconical tubercle on

each side of the disc and the two lobes of the frontal process are prominent. The legs

are annulate. In the female the apical joint of the antenne is shorter than the two

preceding joints united. A female from Aceituno is figured.

(Champion), Guatemala city (Salvin).

We possess ten examples of this species, and there is also one of it in the Oxford

Museum, some of which have been examined by Herr Handlirsch. In this insect the

abdomen is broadly and abruptly foliaceous beyond the middle; the pronotum is

without the usual median constriction at the sides, the latter being feebly trisinuate,

and the anterior and hind angles are acute; the head hasa rather long, raised, bifurcate

frontal process, and two prominent subconical tubercles on each side of the disc; the

apical joint of the antenne is about as long as the two preceding united in the male,

much shorter in the female. The broad transverse dark fascia on the elytra some-

times extends to the apex; the basal half of the corium and the first three segments

of the connexivum are spotted with whitish or pale testaceous, and there are two

similarly coloured spots on each side of the pronotum anteriorly. A specimen from

San Gerénimo is figured.

This genus is confined to the warmer parts of America, ranging from the Southern

United States to Chili and the Argentine Republic. The species are numerous in

Central America, but of several of them very few individuals have been obtained. The

females, in most cases, differ from the males in being much paler in colour, and there is

sometimes a slight modification in the form of the antenne and connexivum in this sex.

Several species are green in life, this colour changing to ochreous in dried specimens.

Macrocephalus chiefly differs from Phymata in the greatly developed scutellum and the

absence of tarsi to the front pair of legs +.

Hab. Costa Rica; Panama, Taboga I. (Champion).

This is the commonest species of the genus in Central America. It is very like

M. cimicoides, Swed., Westwood’s male specimen of which is contained in the Oxford

Museum; but differs from it in having a less cylindrical apical joint to the antenne

in the male, and the scutellar callus less pointed laterally. A typical male from Chacoj

is figured.

The antero-lateral tooth of the pronotum is usually much longer than the posterior

one. ‘The scutellar callus varies in size, it being considerably prolonged posteriorly in

many of the males before me. The puncturing of the basal half of the pronotum and

of the base of the scutellum is very coarse. The segments of the connexivum are more

or less angularly dilated at their outer apical angle. ‘The femora, tibia, and scutellar

callus are probably green or greenish in life. Herr Handlirsch informs me that he has

seen Stal’s types, and also that of WZ. notatus, Westw., and that he regards them as

varieties of one and the same species, distinct from both M. manicatus (F.) and

M. cimicoides, Swed., of North America.

3. Moderately elongate, narrow; ochraceous, the head with an olivaceous mark surrounding the ocelli behind,

the posterior portion of the pronotum, the corium, and the scutellum, the median callus excepted, pale

brownish-olivaceous ; the antenne, the buccal lamine, the front of the prosternum, and a streak on

each side of the median callus of the scutellum in front, fuscous; the legs flavous, the tibie and tarsi

green; above and beneath thickly studded with small smooth pallid granules, these giving a mottled

appearance to the scutellum ; the posterior portion of the pronotum and the median callus and base of the

scutellum coarsely and closely, the rest of the scutellum and the corium finely, punctate. Antenne

moderately stout, joint 4 nearly as long as the others united, 3 longer than 2. Pronotum with the lateral

angles obliquely truncate; the two dorsal carine prominent, converging anteriorly, and reaching the

anterior lobe. Scutellum gradually narrowing from the middle forwards, with a large lanciform

median callus extending to far beyond the middle, and also with a smooth median carina. Abdomen

oval, the connexivum moderately wide, the fifth segment only subangularly projecting laterally at the

outer apical angles.

Length 8, breadth 3 millim.

Hab. Nicaracua, Chontales (Janson 1).

Differs from M. notatus (3) in the more slender antenne, with much longer apical

joint, the obtuse, unraised lateral angles of the pronotum, the closely punctured scutellar

callus, the rounded sides of the connexivum, and the more coarsely and closely granulate

surface. The insect is more elongate and less attenuate than the male of M. panamensis,

and has the scutellar callus very differently shaped, the granulation much closer, &c.

This species is unknown to Herr Handlirsch, who informs me that it is certainly

undescribed.

transverse black fascia before the middle; the antenne black, the second and third joints, and the base

and apex of the fourth, obscure ferruginous; the body beneath ochraceous ; the anterior femora and tibis

nigro-fuscous, the intermediate and hind legs fusco-testaceous; above and beneath, the basal joints of the

antenne, the coxe and femora, and the two hinder tibie, sparsely studded with smooth minute granules ;

the basal half of the pronotum and the basal third of the scutellum closely and somewhat coarsely, the

corium and the rest of the scutellum more finely, punctured, the median callus with a few coarse scattered

punctures only. Antenne moderately stout, joint 4 a little longer than the others united, 3 longer

than 2, Pronotum with the lateral angles obliquely truncate; the two dorsal carine converging

anteriorly and reaching the anterior lobe. Scutellum slightly narrowing from the middle forwards, and

also narrowing behind, with a raised subpiriform median callus and a smooth median carina, the callus

extending to a little beyond the basal third and pointed behind. Abdomen oval, the connexivum rather

narrow and rounded externally.

. Broader, less attenuate behind; ochraceous, the head and the basal half of the pronotum mottled with

fuscous; the scutellum fuscous or brownish, with a faint curved fascia towards the apex, an indistinct

apical spot, the median callus, and the granules, flavous; the legs slightly suffused with green; the

apical joint of the antenne shorter and more pointed, scarcely as long as joints 1-3 united; the abdomen

cordate, with the connexivum much broader; the lateral angles of the pronotum obliquely truncate or very

feebly emarginate at the tip.

Length 8, breadth 34-32 millim.

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

One male and two females. Differs from Jf. notatus in all its varieties in the truncate

or very feebly emarginate lateral angles of the pronotum, the much finer puncturing of

the basal half of the latter, the larger apical joint of the antenne, the relatively shorter

median callus of the scutellum, and the rounded sides of the connexivum.

From the allied M. leucographus, Westw., from Haiti, and from MM. westwoodi, Guér.,

from Cuba, it may be known by the pale scutellar callus, and from JZ. westwoodi, in

addition, by the lateral angles of the pronotum not being raised (fide Handlirsch).

Hab. Mexico, Omilteme in Guerrero (H. H. Smith 1).

Six males and one female of the typical form have been obtained. The variety is

represented by an imperfect female example. The male of M. granulatus may easily

be known by its variegate colour, the segments of the connexivum being spotted and

the pale granules on the scutellum forming definite markings. The female, as in

M. lepidus and others, is much paler and more uniformly coloured. The long third

joint of the antenne is a conspicuous character in the present species. ‘The insect is

unknown to Herr Handlirsch.

latter subequal. Pronotum rather broadly dilated at the sides, the lateral angles slightly excised (forming

two very short obtuse teeth) and with their anterior margin feebly dilated and reflexed at the middle ;

the two dorsal carine short, very little raised, slightly converging in front, and reaching the anterior

lobe. Scutellum narrowing from the middle forwards, with a smooth sharp median carina, which is

thickened at the base. Abdomen broad-oval, the connexivum wide and rounded externally.

Length 61, breadth 3 millim.

Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith }),

One example, evidently discoloured. Very like M. stali, Handl.; but differing from

the female of that species in the much more finely punctured pronotum and scutellum,

as well as in the shape of the lateral angles of the pronotum, these having their oblique

anterior margin slightly dilated and reflexed at the middle. In certain lights the

ochraceous patch at the base of the scutellum appears to be limited posteriorly by an

oblique darker stripe. The insect is unknown to Herr Handlirsch.

Two species were confused by Stal under the name MM. lepidus, the name UV. stéli

being applied to one of them by Handlirsch. Of the latter we have received numerous

examples of both sexes from Guerrero, the males agreeing perfectly with the types of

description. Of the variety I have seen three males and two females. In the typical

form of UM. stali the anterior lobe of the pronotum is coarsely granulate, the granules

at the sides being pointed in both sexes (a character not mentioned by Stal), and the

teeth on the underside of the head, as well as those on the front of the prosternum

and on the front coxe, are sharp; the scutellum in the male (the base of the median

carina excepted) is black or blackish, with two subtriangular yellow spots on each side

externally, and the anterior lobe of the pronotum (as in IZ. prehensilis) is more or less

blackish or fuscous in this sex. A male and female from Chilpancingo are figured.

Handl., from the central plateau and Pacific slope of Mexico, but differing from it in

having the pronotum more finely granulate in front, with the posterior portion more

convex and the dorsal carinze more prominent, and the scutellum more depressed below

the base ; the males, too, are dissimilar in colour, those of the present species having

the anterior lobe of the pronotum pale and the scutellum less marked with black or

fuscous, the median fascia being here separated from the apical spot, this being the

case in the female also. The yellow streak on the base of the scutellar carina is usually

dilated laterally, forming a narrow diagonal mark. Two species having been confused

than the three females from Georgia and Texas before me (including Westwood’s type

of M. pallidus), and has the scutellum more finely punctured. The insect cannot be

associated with either of the forms of MM. stali, on account of the finely and simply

granulated sides of the anterior lobe of the pronotum. The pronotum is more flattened

behind than in MW. lepidus.

the apex, the excision forming two short teeth ; the two dorsal carine prominent, subparallel, reaching the

anterior lobe. Scutellum narrowing a little forwards, rounded at the apex, and with a smoota, prominent

median carina, which becomes much stouter towards the base. Abdomen cordate, the connexivum wide,

the first segment feebly subangularly dilated laterally at the apex.

as to form a variegate pattern. There is no trace of a dark transverse median fascia on

the scutellum and connexivum in the male. Allied to M. asper, Stal, from Venezuela,

but more robust, with shorter spines and hairs, and also differing from it in the absence of

the protuberances on the pronotum (fide Handlirsch). Chiacam specimens are figured.

AGREUOCORIS.

Agreuocoris, Handlirsch, Ann. k. k. naturhist. Hofmus. xii. p. 217, fig. 32 (1898).

The following is a translation of Herr Handlirsch’s description of this genus and

species :—

“Head long, shaped as in the genus Glossopelta, Handl., nearly cylindrical, without frontal projection, and

without grooves for the antenne at the sides, or a groove below or above the eyes; tylus well-defined ;

juga as in Glossopelta, &c.; gens strongly produced, the buccule small, but well-defined, both without

grooves for the antenne; rostral groove not wider than the rostrum, distinctly margined ; eyes and ocelli

as in Glossopelta ; rostrum strong and straight, with the first joint much longer than the second ; (antenna

with joints 2-4 wanting in the unique example seen). Thorax as in Glossopelta, the anterior portion of

the pronotum well separated from the posterior portion, the lateral angles strongly developed and bent

upwards, the median groove distinct, the carina not very much raised; sides without antennal grooves.

Angles of the prosternum produced, enclosing the tip of the rostrum. Scutellum very similar to that of

Glossopelta, elongate, tongue-like, and extending to the apex of the abdomen. Anterior wings similar to

those of Glossopelta, the corium narrow, with the third and fifth veins united; the third vein of the

membrane forked, the cells between the fifth and seventh veins very much as in Glossopelta, &e. Hind

wings with a well-developed hamus and anal appendage; the seventh and ninth veins divided. Inter-

mediate and hind legs very like those of Glossupelta, short and stout (anterior pair broken off). Abdomen

not very flat, similar to that of Glossopelta, broadly heart-shaped, with strongly raised. sides and feebly

emarginate apex. Sculpture and colour as in the allied genera.”

This genus is closely allied to Macrocephalus, differing from it in the venation of the

membrane and in the absence of.a channel on the anterior side of the gene. ‘The first

(third) vein of the membrane is forked in Agrewocoris, and simple in Macrocephalus.

“3. Form similar to that of Glossopelta acuta, Hand]. Head nearly cylindrical, closing the gene entirely in

front, the edge of the rostral groove not much produced, unarmed; ocellar elevations feebly raised; first

joint of the antenne rather thin, not pointed. Pronotum one and a half times broader than long,

distinctly depressed at the middle. plainly carinate, the lateral projections strongly curved upwards,

slightly directed backwards and distinctly emarginate at the tip. Angles of the prosternum strongly

produced. Scutellum long, tongue-shaped, nearly extending to the apex of the abdomen, without

distinct median carina. Membrane dark brown. Abdomen broadly heart-shaped, decidedly broader

than the thorax, the terminal segment slightly emarginate, the connexivum with entire margins, only a

little produced at the angles of the first and second segments. Body smooth, the head finely granulate,

the anterior portion of the pronotum and the sides of the breast more coarscly granulate, like the exposed

parts of the abdomen; behind the middle, the pronotum is very closely and strongly punctured ; scutellum

coarsely punctured at the middle, the sides finely and closely punctured. Underside pale light brown. The

head above and laterally almost black; the pronotum black-brown above, near the edges brownish, behind

the middle with some reddish spots; scutellum nearly black ; the exposed sides of the abdomen brownish ;

corium and first joint of the antenne dark; the rostrum and legs brownish. Length 10 millim.”

ARADUS. 65

Fam. ARADIDZ.

This family is represented in Central America by about the same number of species

as the Tingitide, and by nearly as many genera, viz. twenty-three, two only of these

being at all numerous in species, e. g. Brachyrrhynchus and Newroctenus. Dr. Bergroth

(1892) gives the total number of Nearctic Aradide as thirty-six (belonging to five

genera), of which twenty-five belong to the one genus Aradus; and of the Palearctic

species as sixty-seven, with the same number of genera. The Neotropical Aradide are

of sluggish habits, living under the bark of decaying trees, often in gloomy places in

the forest. With one exception, Aradus falléni, Stal, the whole of the Central-American

species belong to the Brachyrrhynchine, the rostrum in this subfamily being very

short and received in a deep groove along the underside of the head. All the known

American genera but one *—WMelanosterphus, Stél—are represented within our limits,

whence five others are added. Some of the species are very local, and the males appear

to be very much rarer than the females. We possess two pairs still 7m coitu, showing

that the female is placed above the male during copulation.

I am indebted to Dr. Bergroth, who has made these insects his special study for many

years, for the loan of several of his types, as well as for a great deal of assistance in

working out the large number of Central-American species; and also to Dr. Aurivillius

for the loan of various American Aradidée described by Stal.

Three examples. Closely allied to C. pallipes, Stal, from Brazil; but differing from

it in the form of the antenne (C. pallipes being described as having joints 2-4 each a

little longer than 1 and subequal in length) and other particulars. The connexivum

has three prominent blunt teeth (two black and one ochraceous) on the outer border of

each segment; viewed laterally, it is divided into two parts, a dorsal and ventral, each

of which is similarly armed.

CALISIOPSIS, n. gen.

Head very broad, short, truncate behind, concave on each side between the eyes, which are large and promi-

nent, the post-ocular portions short and dentiform, the antenniferous processes broad and bidentate at the

apex; the apical process broad, as long as the rest of the head, reaching to the middle of the terminal joint,

of the antenne, unemarginate at the tip; antenne very short, joints 1-3 exceedingly short and subequal

in length, 4 ovate, stout, and a little longer than the others united; rostrum reaching the base of the

head. Pronotum convex behind, bisinuate at the base, irregularly quadricarinate on the disc. Scutellum

completely covering the elytra, extending to a little beyond the apex of the fifth abdominal segment,

broadly triangularly raised in front and carinate down the middle thence to the apex. Connexivum

broad, denticulate at the sides. Anterior cox moderately, the intermediate and hind coxe widely,

separated. Venter rather convex. Legs very short, the femora moderately stout and unarmed.

This genus includes a single species from the Isthmus of Panama. It differs from

Calisius, Stal (= Aradosyrtis, Costa), in the very differently formed head and antenne.

on account of his having wrongly referred the genus to the Tingitide.

Three Central-American species are referred to this genus, based upon P. incrustatus,

Stal, from Rio Janeiro, the type of which is before me. In all these insects the surface

is thickly coated with a hard pallid incrustation, which is moulded into peculiarly

shaped callosities on the head, pronotum, and scutellum, the two grooves on the upper-

side of the head forming cavities for the reception of a portion of the antenne in

repose. They are difficult to describe in an intelligible manner, and will be more

easily identified from our figures.

Sixteen specimens of the typical form and one of the variety; the latter may prove

to belong to a distinct species. Recognizable by the more or less inflated prominence on

the middle of the scutellum and the bilobed prominence on the disc of the anterior

lobe of the pronotum. In the specimen from Bugaba ( @ ) (fig. 6), the outer apical

angles of the sixth connexival segment are subangular, instead of obtuse, as in all the

other examples obtained, including both sexes.

Seven examples. One of those from Bugaba has an additional transverse prominence

on each side of the disc of the posterior lobe of the pronotum, and the anterior angles

of the latter, as well as the post-ocular portions of the head, more acute.

This species may be separated from P. personatus by the shorter third joint of the

antenne (this joint not being longer than the fourth in the present insect), the more

strongly bifurcate prominence on the middle of the anterior part of the pronotum, the

posterior lobe of the latter being margined towards the sides in front as well as behind,

and with differently shaped callosities on the disc, the uninflated median prominence

on the scutellum, the more produced apical angles of the sixth abdominal segment, &c.

A pair from Bugaba are figured, showing the extreme forms.

CARVENTUS.

Carventus, Stal, Hemipt. Afric. iii. p. 82 (1865) ; Enum. Hemipt. iii. pp. 1389, 140 (1878).

Of the six described members of this genus, all are eastern but one, C. mexicanus,

Bergr. The American species closely resembles Stal’s type of C. denticollis, from

Mysol (now before me); but it is without the abruptly projecting tooth at the middle

of the sides of the pronotum, and also has the post-ocular portions of the head longer

and the apical lobes of the pronotum emarginate in front.

The type (6) of this species, communicated by Dr. Bergroth, is not in good

condition, the incrustate portions of the head and pronotum being apparently injured

or not fully developed. A description of the female is now given from the better-

preserved specimen from Chiriqui :—

2. Oblong-ovate, ferrugineo-fuscous, the head, the anterior lateral lobes of the pronotum, the sides of the

scutellum, and the connexivum covered by a thick greyish-ochreous incrustation ; the antenne ferrugineo-

testaceous, the legs testaceous. Head broad, subtriangular, the sides of the narrow basal portion obliquely

converging posteriorly ; the post-ocular portions swollen and dilated laterally to beyond the eyes; the

antenniferous processes long, spiniform, subparallel; the apical lobes long; the callosities forming a

rather broad median ridge, enclosing a rostriform process in front; antenne slender, joint 1 moderately

stout, extending to nearly one-half beyond the apical lobes of the head, clothed with a few short hairs,

2 rather more than half the length of 1, 3 about two and one-half times the length of 2, 4 a little longer

than 2, clothed with long hairs at the tip. Pronotum transverse, trapezoidal; the anterior lateral lobes

obliquely emarginate in front and also emarginate at the sides, with prominent angles, the callosities with

punctiform impressions; the posterior lobe slightly dilated and callous at the sides, not incrustate.

72 HEMIPTERA-HETEROPTERA.

Scutellum with a thick callous margin at the sides, widening a little anteriorly. Abdomen oval, truncate

at the apex ; the incrustation of the under surface projecting a little beyond the lateral margins towards

the apex of each segment, their outer apical angles thus appearing somewhat prominent; the genital

lobes moderately stout.

Length 5, breadth 21, millim.

Differs from the type (¢) in having the head, pronotum, and connexivum more

thickly incrustate; the head broader, with the post-ocular portions swollen and

projecting outwards to considerably beyond the eyes; the basal joint of the antenne

a little more elongate ; the abdomen more rounded at the sides, the outer apical angles

of each segment not projecting. Both specimens have a scar on the middle of

the disc of the pronotum, suggesting the possibility of a portion of the incrustation

being broken off.

PSOROSOMA, n. gen.

Head subquadrate, abruptly constricted into a short neck behind, with two long divergent frontal spines; the

post-ocular portions rectangular, of about the same length and breadth as the eyes; the antenniferous

processes long and stout, terminating in a straight spine ; antenne short, joint 1 stout, curved, extending

as far as the apex of the frontal spines of the head, 2 slender, shorter than 1, thickened at the apex,

3 very slender, about one-half longer than 2, constricted at the base and slightly thickened at the tip,

4 piriform, half the length of 3; rostrum very short, not nearly reaching the base of the head. Pronotum

very much wider than the head, as long as broad, broadly emarginate at the base for the reception of the

basal portion of the triangular scutellum ; the posterior lobe short, transversely convex, arcuately dilated

at the sides; the anterior lobe parallel, with five prominences in front (a median and two lateral on each

side), the outer ones acute. Elytra reaching the apex of the fifth abdominal segment; corium extending

to about the middle, gradually tapering behind; membrane with prominent nervures. Abdomen long

and subparallel, a little wider than the pronotum, convex beneath; connexivum broad, the spiracles

placed close to the outer margin and partly visible from above, the outer apical angles of the sixth

segment produced posteriorly into a long triangular process. Legs rather elongate, the femora moderately

stout and finely setose, the tibie: slender and clothed with very short hairs. Body narrow, elongate,

not granulate, in great part covered by a thick pallid incrustation, which is moulded into irregular

callosities on the head, pronotum, and scutellum.

This genus, represented by a single species from the State of Panama, is nearest

allied to Proxius and Carventus, differing from both in the structure of the head,

antenne, &c. Its narrow, flattened, elongate shape and the bifurcate apex of the

abdomen give it a Forficuliform appearance.

1. Psorosoma forficulinum, n. sp. (Tab. V. figg. 15,2 ; 15a, antenne. )

Q. Obscure testaceous, the head, the pronotal and scutellar callosities, and the connexivum whitish-ochreous,

the third and fourth antennal joints fuscous. Head with an oblique ridge on each side running back-

wards from the inner margin of the eyes, two short parallel ridges in front, and a short median ridge,

the latter excised in front for the reception of a short rostriform process ; antennw with the basal joint

and the apical half of the fourth very sparsely pilose. Pronotum with irregularly confluent callosities

on the anterior lobe, these forming five processes in front—the intero-lateral one very prominent and

obliquely truncate, the outer one divergent and acute; the posterior lobe set with a few bristly hairs,

with a space in the middle and the sides broadly callose, the lateral portions feebly transversely wrinkled.

Scutellum carinate down the middle, and with the sides slightly raised. Abdomen very gradualiy

We have obtained fourteen specimens of this species from within our limits, all but

one of them being from Chiriqui.

The male of the insect described by Stal as H. cordatus (Fabr.), communicated by

Dr. Aurivillius, differs from the Chiriqui examples of the same sex in having the

abdomen slightly constricted at the sides beyond the middle, with the apical angles of

the fourth segment a little less prominent ; but this peculiarity is more apparent than

real. ‘The females agree precisely with the types of H. annuliger, Stal, and H. cincti-

cornis (Walk.). Of the latter there are five specimens (¢ 2) in the British Museum.

H. cordatus chiefly differs from H. flaviventris in having the two inner callosities on

the pronotum more approximate, the narrow groove between them being without

conspicuous tubercles or ruge; it also has the basal joint of the antenne usually a

little more elongate and the apical process of the head more feebly bilobed.

The insect is also constantly paler in colour. The antenne incline to ferruginous,

the basal joint included, the apex of the third joint and the base of the fourth being

Not uncommon on the Atlantic slope of Guatemala. In the variety subarmatus

the anterior portion of the pronotum is armed with a small tubercle on each side and

has another small tubercle at the anterior angles; it also has the tubercles and ruge

between the inner callosities less prominent, and the outer callosities less raised. The

abdomen of the male is shaped as in H. cordatus; the connexivum is more or less

spotted with ochracecus, and the ventral surface, the apex excepted, is usually of the

same colour. A specimen (d) from Bogota, determined by Stal as H. flaviventris,

and the type (2°) of H. subarmatus have been communicated by Dr. Aurivillius.

We figure two specimens agreeing with these: a male of the typical form from

Bugaba, and a female of the var. subarmatus from La Tinta.

HELENUS.

Helenus, Buchanan White, Journ. Linn. Soc., Zool. xiv. p. 485 (1879).

The single species referred to this genus, P. hesiformis, Buch. White, from the

Amazons, chiefly differs from Hesus in the shaggy pubescence of the body, antenne,

and legs, the more irregular anastomosing neuration of the membrane, the short apical

joint of the antenne, and the sulcate sternum and venter. In the second species now

added the sternum is scarcely more deeply sulcate than in Hesus, this insect having

the head much smaller than in that genus, with a short apical process.

* In the British Museum there is an immature male specimen of a Hesus from Pard nearly agreeing with

Stl’s description of H. acuminatus. It has the fifth connexival segment more dilated at the apical angles than

in H. cordatus (¢), and the abdomen itself broader behind, the pronotum with two ruge between the two

median callosities.

HELENUS.—MIORRHYNCHUS. (65)

1. Helenus hirsutus, n. sp. (Tab. V. fig. 16, ¢.)

Subparallel and a little widened posteriorly (¢), oblong-ovate (@), nigro-fuscous or black, the second and

third joints of the antenne at the base, and the basal halves of the tibie, more or less ferruginous; the

surface sparsely clothed with very short, matted, decumbent, brownish-ochraceous hairs, with long, fine,

scattered, pallid erect hairs intermixed. Head much longer than broad, comparatively small, rugose ;

the apical process short, parallel, shortly bilobed at the tip, extending very little beyond the antenniferous

processes, which are obtusely spiniform in front and slightly rounded externally ; the post-ocular portions

short, rounded ; the eyes rounded and rather small, prominent; antennz with joints 1 and 3 subequal in

length, 1 stout, rugose, extending to nearly three-fourths beyond the apical process of the head, villose,

2 slightly longer than 4 and much shorter than 3, 4 a little more than half the length of 3, 2-4 with

scattered hairs. Pronotum transverse, irregularly rugose and subgranulate, sinuate at the sides and

much narrowed anteriorly, the base broadly and obliquely produced on each side behind, truncate opposite

the scutellum ; the anterior portion rounded externally, constricted into a very short neck in front (in

one specimen with prominent anterior angles), the two inner callosities flattened and narrowly separated ;

the posterior portion very broad, rounded at the sides anteriorly and parallel behind, the sculpture

consisting of short, transverse, sinuous, interrupted ruge. Scutellum transversely rugose. Corium

granulate, parallel and not wider than the pronotum externally, rounded at the apex, and arcuate-

emarginate within. Membrane with irregular anastomosing nervures. Abdomen a little rounded at the

sides in the female, more parallel in the male, truncate at the apex; connexivum sparsely punctured,

the outer apical angles of segments 1-4 slightly projecting, that of the fifth segment rounded; the sixth

segment abruptly and obliquely narrowed, subangularly dilated at the middle in the male; genital lobes

short and stout; spiracles placed near the outer margin, those on the fifth and sixth segments marginal.

Beneath rugose, the meso- and metasternum depressed along the middle. Legs sparsely villose, the

femora stout and rugose.

Length 84-9, breadth 33-4 millim. (¢ ?.)

It is possible that this insect may be inseparable from H. hesiformis, Buch. White

(the type, ¢, of which I have not seen), but the Amazonian species is described as

ferruginous in colour, and strongly villose and setose, with the apical process of the

head unarmed ; it would also appear to have a much deeper groove along the sternum

and venter.

the neck-like apex not wider than the head, granulate; the posterior portion conspicuously granulate,

slightly callous at the sides, the latter parallel behind, rounded at the middle, and converging in front ;

the anterior portion rounded at the sides in front, the outer callosities with a row of short hairs similar

to those on the margins. Scutellum transversely wrinkled on each side of the indistinct median ridge,

the margins slightly thickened. Corium arcuate-emarginate within. Abdomen widening to about the

middle and slightly narrowing beyond ; connexivum rugosely punctured, the outer apical angles of the fifth

ARTAGERUS.

Artagerus, Stal, Rio Jan. Hemipt. i. p. 67 (1860) ; Enum. Hemipt. ii. pp. 139, 142.

In this Tropical-American genus the basal joint of the antenne and the femora and

tibize appear to be excessively stout, but this is partly due to the spaces between the

sete being filled up by an earthy incrustation, which usually leaves the tips only of

the sete visible. The other joints of the antenne are very slender. The surface

of the body is also more or less coated with earthy matter, hiding the sculpture and to

‘some extent the very short, coarse, rusty-brown, matted hairs. In the males the sixth

segment of the abdomen is strongly raised in the centre in front of the genital segments,

forcing the apex of the membrane into a vertical position in repose.

Three of the four known species of the genus occur within our limits, whence one

other is now added.

are very conspicuous on the raised portions of the surface; the tarsi and the apical joint of the antenne,

and sometimes the second and third joints also, ferruginous; the basal joint of the antenne and the

femora and tibie thickly setose. Head obliquely narrowing behind the eyes, the latter prominent, the

apical process a little longer than the lateral ones; antenne short, joints 1 and 3 subequal in length,

1 excessively stout, shorter than the head, 2-4 slender, 2 slightly longer than 4, 4 short and piriform.

Pronotum deeply emarginate at the sides and apex; the anterior portion with the two outer callosities

raised and very prominent, the inner ones indistinct, the anterior angles rounded and projecting forwards ;

the posterior portion one-half wider, callous and arcuately dilated at the sides, the disc with two short

posteriorly converging carine, joining the median carina of the scutellum behind. Abdomen broad,

rounded at the sides, the outer apical angles of the connexival segments obtusely projecting, that of the

sixth segment angular or sublobate. Beneath rugulose, the ventral segments each with a small, smooth,

depressed spot in the centre. Legs short, the femora and tibie extremely stout.

antenne and the outer apical angles of the connexival segments much Jess prominent.

From A. histricus (2 ), with which it agrees in the form of the antenne and abdomen,

it may be readily distinguished by the anterior angles of the pronotum not being

Aphleboderrhis, Stal, Rio Jan. Hemipt. i. p. 67 (1868) ; Enum. Hemipt. iii. pp. 140, 142.

A single species, from Brazil, was referred to this genus by Stal, and a closely allied

form from the State of Panama is now added. Pictinus hirticornis, P. tomentosus, and

P. procerulus, Bergr., all from Brazil, also belong to it, and Aradus pubescens, Walk.,

from Central and South America, is perhaps best placed here. This last-mentioned

insect is very dissimilar in appearance from A. pilosa and A. comata, but Dr. Bergroth

informs me that P. tomentosus and P. procerulus are intermediate forms. Our two

species may be separated thus :—

Anterior angles of the pronotum broadly dilated and ciliate; head transverse,

the apical process subtriangularly dilated, cleft at the tip; apical joint of the

anteune shorter than the third; hairs on antenne, body, and legs curled

and decumbent . . 2. 1. 1 1 1 ee ew ew ew ee we ee ee COmaLA, DL SP.

Oblong, rather broad, piceous or piceo-ferruginous, the antenns and legs obscure ferruginous, the membrane

smoky, with an obscure luteous mark near the apex of the corium; the antenna, legs, and upper surface

somewhat thickly clothed with long, curled, fulvous hairs, these forming a dense fringe along the margins

of the anterior portion of the pronotum and two rows on its disc; the bare portions of the surface almost

smooth. Head transverse, rounded at the sides behind the rather large eyes; the apical process short,

subtriangularly dilated from a little before the base, and cleft at the tip, scarcely extending beyond the

short antenniferous processes; antennze moderately long, stout, 1 thicker than the others, extending to

about three-fourths beyond the apical process of the head, 2 one-half the length of 3, 3 a little longer

than 1, 4 one-half longer than 2, clavate towards the tip. Pronotum transverse, feebly emarginate

behind ; the anterior portion dilated laterally into a broadly rounded, slightly raised lobe, and nearly as

wide as the posterior portion, the disc appearing depressed ; the posterior portion sparsely granulate, the

sides rounded anteriorly and parallel behind. Scutellum transversely wrinkled and with a median ridge.

Corium extending to the apex of the first segment. Abdomen a little more parallel in the male than in

the female, the sixth segment obliquely narrowing in both sexes; the terminal genital segment of the

male very convex, transversely cordate, the genital lobes very short; the sixth segment subtruncate at

the apex in the female, leaving the emarginate first genital segment narrowly exposed. Beneath almost

smooth ; the meso- and metasternum very broadly depressed in the centre, the first ventral segment with

a deep depression in the middle, the following segments flattened along the median line. Legs stout.

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

Four males and four females. Differs from A. pilosa, Stal, from Rio Janeiro, the

type of which is before me, in the broadly rounded and strongly dilated sides of the

anterior portion of the pronotum (the pronotum appearing abruptly constricted at

the middle laterally), the hairs along the margins of which are coarser, curled, and form

a close fringe. There is also no trace of the two tubercles on the disc in front, present

in A. pilosa, but not mentioned by Stal. The under surface is almost smooth in the

present species, rugose in A. pilosa, a space along the middle of the venter excepted.

A pair from Bugaba are figured.

Hab. Mexico, Teapa in Tabasco (H. H. Smith); Guatemata, San Juan in Vera Paz

(Champion) ; Panama, Bugaba, Volcan de Chiriqui (Champton).—Amazons, Paré!.

We possess eight examples of this species, five of which are from Chiriqui, these

agreeing with the type in the British Museum, I had at first treated this insect as the

type of a new genus, but Dr. Bergroth, who has made the Aradide his special study

for many years, is of opinion that it cannot be separated from Aphleboderrhis. In some

specimens the surface is partly covered by a pallid incrustation. A male from Teapa

‘and a female from San Juan are figured. |

PICTINUS.

Pictinus, Stal, Enum. Hemipt. i. pp. 140, 145 (1873).

Dr. Bergroth informs me that of the numerous species referred by him to Pictinus,

four only (P. aurivillii, P. fronto, P. invalidus, and P. modigliani) really belong to it,

P. hirticornis, P. procerulus, and P. tomentosus pertaining to Aphleboderrhis, and

P. asiaticus and P. pusio to a new genus. One only was known to Stal, P. cinctipes,

the type of the genus. The six Central-American species, all of which are treated as

new, differ inter se in the form of the head, antenne, and pronotum, and to some

extent in the position of the spiracles, these being sometimes placed on or so near the

lateral margins of the abdomen as to be visible from above. The genus seems best

placed here. The neuration of the membrane is obsolete or very indistinct, a character

separating Pictinus from most of the allied forms.

8. Dysodius brevipes. (Tab. VI. fig. 13, 3.)

Dysodius brevipes, Bergr. Wien. ent. Zeit. xvii. p. 26 (¢) (Jan. 1898)".

Broad ovate, ferrugineo-fuscous, the connexivum more or less mottled with fuscous; the upper surface rather

coarsely granulate, and here and there coated with a pale luteous incrustation. Head longer than broad,

the granules very coarse, becoming spiculiform at the sides and base; the spiniform antenniferous

processes long, acute, and divergent; the apical process long and stout, bifid at the tip, armed with

obliquely projecting spines on each side; the post-ocular portions broad, semi-lunate, curving outwards and

forwards to beyond the eyes, terminating in a rather long spine in the male; antenne moderately long,

joint 1 stout, about one-third longer than the apical process, 2 considerably shorter than 1, 3 a good deal

longer than 2, 4 one-half the length of 3. Pronotum with the apical lobes broad, moderately long,

slightly curved, rounded laterally and at the tip; the posterior portion separated from the anterior

portion by a deep groove, rounded at the sides behind, becoming subparallel forwards; the lateral and

apical margins (the lobes included) coarsely crenate. Abdomen broad, rounded and crenulate at the sides

in both sexes; the genital lobes broad in the female, narrow in the male; the ventral surface somewhat

closely, rather finely punctate, the raised central portion of the first segment strongly transverse. Legs

short, the hind femora extending very little beyond the abdomen. .

Length 13-134; breadth of the anterior part of the pronotum 33-4, of the abdomen 7 millim. (¢ 9.)

Allied to D. crenulatus, Stal, but differing from it in having the pronotum subparallel

at the sides behind the apical lobes, these latter being broader and less divergent than

in that species; the head is also more dilated at the sides behind the eyes, and the

legs are shorter. The longer antenne, the longer, spiculiferous process of the head,

and the less divergent apical lobes of the pronotum separate it from D. ampliventris.

Of this species, the only known member of the genus, two female specimens were

obtained by myself in Chiriqui. The term “levis” is misleading in the description,

and applies only to the scattered glabrous portions of the very uneven surface, which

is in great part covered by short, matted, decumbent, rusty-brown hairs, as well as by

fine scattered erect hairs (which extend to all the joints of the antenna, as well as to

the legs), these latter not being mentioned by Stal. The type has been communicated

by Dr. Aurivillius.

LOBOCARA.

Two species are referred to this genus by Dr. Bergroth, L. oblonga from the Argentine

Republic and Z. ovata from Mexico. The latter is widely distributed in Central

America, extending southwards to Nicaragua.

Of the forty-eight species of this widely distributed genus enumerated by Lethierry

more or less elongate, and the corium extending to about as far as the middle of the

second segment, it being sometimes emarginate within (B. handlirschi). The apical

joint of the antenne is piriform (B. leviventris), ovate (B. maculiventris), or oblong-

ovate (B. emarginatus), sometimes longer than the second (4. nanus). The rostrum is

short, but in two of the new species described (B. leviventris and B. sinuatus) it

reaches the front of the prosternum; the rostral groove is sometimes narrowed and

closed behind (B. handlirschi). The spiracles vary a little in position according to the

species, irrespective of the width of the connexivum.

BRACHYRRHYNCHUS. 97

Two females, agreeing well with a specimen of the same sex from Texas (now before

me), determined by Stl as B. lobatus (Say). As there is considerable doubt about the

determination of many of Say’s species, a fresh description is given from the Central-

American examples. This species resembles B. leviventris, but has the venter

punctured and coated, like the rest of the under surface, with a pallid incrustation

(a character not mentioned by Say); the head has short apical and antenniferous

_ processes, the anterior portion of the pronotum is less dilated and not reflexed at the

sides, the basal joint of the antenne is stouter, the membrane paler, &c.

dilated and broadly rounded at the sides, the callosities not prominent; the posterior portion much

broader, rounded at the sides anteriorly and subparallel behind. Corium rounded at the apex.

Connexivum broad—in the female somewhat rounded at the sides posteriorly, with the sixth segment

emarginate at the apex, leaving the first. genital segment rather broadly exposed, the latter with two

prominent rounded lobes; in the male with the fifth and sixth segments obliquely narrowing, the latter

produced into an obtuse lobe behind. Terminal genital segment of the male cordate; the lobes of the first

genital segment long. Beneath dull and finely rugulose ; the venter somewhat flattened, the segments

each with a smooth spot in the middle. Femora asperate.

One male and three females. Very like B. neotropicalis, but more ovate in both

sexes, the hairs on the upper surface, antenne, and legs longer, finer, and erect, the

connexivum finely rugulose. The comparatively long and very fine hairs are particularly

noticeable on the head, antenne, and legs, this character separating the species from

all the other Central-American members of the genus. The insect is unknown to

One pair. Distinguishable by the raised and broadly, arcuately dilated sides of the

anterior portion of the pronotum, the median constriction appearing deeper than in

any of the other species of the genus here described. The obliquely truncate inner

margin of the corium will separate it from B. lobatus, apart from other characters.

B. obscurus (Dist.), from Ecuador, is an allied form, but has a more transverse,

smoother pronotum, &c.

BRACHYRRHYNCHUS. 99

9. Brachyrrhynchus regularis, n. sp. (Tab. VII. fig. 8, 3.)

Oblong-ovate, rather broad, fuscous, the antenne and tarsi obscure ferruginous, the outer apical angles of the

connexival segments ochraceous, the membrane lurid, with dark nervures; the upper surface rather finely

Hab. GuatemaLa, El Tumbador 2500 feet (Champion: ¢); Costa Rica, Turrialba

(Biolley: 2).

Two males from the Pacific slope of Guatemala, and a single female from Costa Rica,

the latter communicated by Dr. Bergroth. Distinguishable by the very long post-ocular

spines, in connection with the moderately sinuate and rather coarsely crenulate sides

of the pronotum, the evenly rounded sides of the connexivum towards the apex in

the male, and the very broad terminal genital segment in this sex. It approaches

B. granuliger, Stal, from Brazil, the type (¢ ) of which is before me, but differs from

that species in the evenly rounded sides of the connexivum, the less coarsely granulate

upper surface, the short genital lobes, &c.

10. Brachyrrhynchus neotropicalis, n. sp. (Tab. VII. fig. 4, ¢.)

Oblong-ovate (9), slightly widened behind (¢), rather broad, varying in colour from black with the

connexivum piceous to almost entirely fusco-ferruginous; the membrane blackish or fuscous, more or

less marked with obscure luteous round the apex of the corium; the upper surface granulate, the

connexivyum comparatively smooth, and clothed with scattered, very short, curled, rusty-brown hairs; the

at the base; the apical process reaching to a little beyond the middle of the first antennal joint, rounded

and sometimes slightly emarginate at the tip; the spiniform antenniferous processes acute, divergent ;

the post-ocular portions dilated laterally into an acute spine, which usually extends outwards as far as or

to a little beyond the eyes; antenne rather slender, with joint 1 stouter, 2 a little shorter than 1 and

slightly longer than 4, 8 much longer than 1] and nearly twice as long as 4, 4 piriform. Pronotum feebly

portion dilated on each side into a broadly rounded lobe, the callosities each with indications of a short

ridge; the posterior portion much broader, rounded at the sides anteriorly and subparallel behind.

Scutellum sparsely granulate and with an indistinct median ridge. Corium more or less rounded at the

apex. Connexivum broad—in the female feebly rounded posteriorly, with the sixth segment sometimes

genital segment of the male transversely cordate; the lobes of the first genital segment long. Beneath

(the genital segments excepted) finely and shallowly rugulose, dull, the venter flattened, the segments

each with a small smooth spot in the middle. Femora coarsely asperate.

Length 63-84, breadth 24-34 millim. (6 9.)

Joaquin in Vera Paz, Duefias (Champion: 3 ¢ ).

Var. The elevations of the upper surface somewhat thickly clothed with rusty-brown or fulvous hairs; the

membrane entirely black.

Hab. Guatemata, San Juan and Tamahu in Vera Paz (Champion: 9° ).

Seventeen specimens, four of which belong to the variety, the more numerous hairs

on these examples being perhaps due to their fresher condition. The description is

mainly taken from Guatemalan specimens, three only having been seen from Mexico.

This variable species is nearly allied to B. me@stus (Stal), the type of which is before

me; but differs from it in the relatively less elongate and more ovate shape, the

more deeply sinuate sides of the pronotum, the more flattened venter, the smoother

connexivum, and the more asperate femora. Fresh specimens have four short distinct

ridges on the anterior part of the pronotum and three lines on the scutellum, formed

in part by the short curled hairs. The single (2) example belonging to the Vienna

Museum is labelled B. americanus, Spin.; but I cannot accept this determination as

correct, the male of the present insect not agreeing with Spinola’s figure (<¢ ), and

B. americanus, moreover, is a Chilian species. We figure a male from San Joaquin.

11. Brachyrrhynchus angustatus, n. sp. (Tab. VII. fig. 6, 2.)

Oblong-ovate, narrow, nigro-piceous or black, the connexivum sometimes inclining to ferruginous, the

membrane blackish; the upper surface granulate, the connexivum rather smooth, and clothed with

extremely short, curled, rusty-brown or fuscous hairs; the legs and antenne shortly pubescent. Head

(exclusive of the apical process) transverse, somewhat rounded at the base; the apical process reaching

to a little beyond the middle of the first antennal joint, feebly emarginate at the tip; the spiniform

antenniferous processes acute, divergent; the post-ocular portions dilated laterally into an acute spine,

which extends outwards as far as the eyes; antennew rather slender, with a stouter basal joint, joints 2

and 4 subequal in length, 3 much longer than 1, 4 piriform. Pronotum feebly emarginate at the base,

constricted at the sides, the margins crenulate;.the anterior portion dilated on each side into a slightly

raised, rounded lobe, the callosities each with a short ridge; the posterior portion very much wider,

rounded at the sides anteriorly and subparalle] behind. Scutellum with a median ridge. Corium obtuse

at the apex, subobliquely truncate within. Connexivum comparatively narrow, gradually narrowing

from the base of the fifth segment in both sexes, the sixth obtusely produced at the apical angle in the

male. First genital segment broadly exposed in the female, with two rounded lobes. Terminal genital

segment of the male cordate; the lobes of the first genital segment long. Beneath rugulose, dull; the

venter flattened, the segments each with a smooth oblong spot in the middle. Femora finely asperate.

Length 5-6,),, breadth 2-23 millm. (d 9.)

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

Six females and two males. Very like B. neotropicalis; but narrower and consider-

ably smaller, with the pronotum strongly constricted at the sides and its anterior

portion relatively narrower, the femora smoother, the corium less rounded at the apex.

narrowed behind, extending to the middle of the first antennal joint, unemarginate at the tip; the

antenniferous processes broad, subparallel, terminating in an acute, short spine in front; the post-ocular

portions short, armed with a very short spine; the eyes comparatively large; antenne rather slender,

with a stout basal joint, joint 3 slightly longer than 1, 4 nearly as long as 2, piriform. Pronotum feebly

emarginate at the base, deeply sinuate at the sides; the anterior portion dilated laterally into a broadly

rounded, slightly raised lobe, the callosities each with a short somewhat prominent ridge; the posterior

portion much wider, rounded at the sides anteriorly and subparallel behind, the margins crenulate.

Scutellam transversely wrinkled, and with a median ridge. Corium with the apical margin slightly

rounded. Connexivum very broad, rounded at the sides, the sixth segment feebly emarginate behind,

leaving the first genital segment narrowly exposed, the latter with two rounded lobes. Beneath rugose,

dull; the venter somewhat flattened, the segments each with a small smooth spot in the middle.

Length 9, breadth 4 millim.

Hab. GuatTemaLa, Chacoj in Vera Paz (Champion).

One example, from the Polochic valley. Distinguishable from all the other Central-

American species by its broad, ovate shape. The head is formed as in B. lobatus,

except that the apical process is not so wide. The sixth connexival segment is less

deeply emarginate at the apex than in the females of B. neotropicalis, B. longipilis, &c.,

nearest allied to B. angustatus, and has the pronotum similarly formed, differing from

it, however, in the much broader general shape, and in the produced apical angles of

the sixth segment in the male. It is more parallel than the male of B. neotropicalis,

and is more rugose beneath.

The description is taken from the type in the Vienna Museum. A male from

Omilteme (. H. Smith) and a female from San Miguelito (Dr. Palmer) may belong to

the same species. The type is very like the female of B. neotropicalis, but is relatively

narrower and has the pronotum very feebly sinuate at the sides. The Omilteme

specimen is narrower than the maies of that insect. B. me@stus (Stal) must remain

as a doubtful species until more ‘specimens are obtained. Mezira mesta, Walk.,

Hab. Norta America, Nevada, Upper and Lower California ?,—? Mexico ! 2,

The above description is taken from five specimens communicated by Prof. Uhler,

one of these being figured on our Plate. The locality “ Mexico,” given by Say, requires

confirmation, the insect perhaps not belonging to our fauna. The stout, rough antenne

separates it from all the Central-American species except B. rugicornis, from which it -

differs in the broader post-ocular portions of the head, the anteriorly emarginate

pronotum, &c. The terminal genital segment of the male is very short, as in B. regu-

laris, a species having much more slender antenne. ‘The corium is obliquely truncated

at the apex, appearing slightly emarginate within.

One example. Very like B. granulatus (Say), from Texas, Florida, &c. *, three

specimens of which are before me, but with stouter and more cylindrical antenne, the

pronotum more deeply sinuate at the sides, the general shape more ovate. The less

constricted, flatter pronotum, the more acute antenniferous processes, and the more

with shorter second joint, the shorter and less acute antenniferous processes, the flatter

pronotum, with the sides less deeply sinuate, the more rounded apex of the corium,

and the more parallel general shape. B. nanusis also very like Nannium elongatulum,

Bergr., from Venezuela, but has the first three spiracles more distant from the margin,

the third antennal joint more cylindrical, and the antenniferous processes and the post-

ocular spines more obtuse.

Length 6, breadth 23 millim.

Hab. Guatumata, Zapote (Champion).

One example. This small species somewhat resembles the North-American

B. granulatus (Say); but it has much stouter antenne, in this respect approaching

B. emarginatus and B. rugicornis, differing from both these insects in the constricted

pronotum, the shorter legs, &c., as well as in size. ‘The two portions of the pronotum

are separated by a rather deep transverse groove, the anterior port on having four

prominent ridges.

COLOBORRHYNCHUS, n. gen.

Head (exclusive of the apical process) transverse, obliquely narrowed behind the eyes, with spiniform

antenniferous processes and a moderately long apical process, which is feebly emarginate at the tip;

antenne with joint 1 stout, and longer than the apical process, the other joints more slender; rostrum

short, not extending beyond the base of the head. Pronotum transverse, sinuate at the sides, very feebly

emarginate at the base, and truncate at the apex; the anterior portion with a curved longitudinal ridge

on each side midway between the flattened inner callus and the margin, and extending forwards

to the slightly raised anterior margin. Scutellum triangular. Corium reaching about as far as the

middle of the second connexival segment, its apical margin truncate. Membrane with a few prominent

nervures. Connexivum broad. Spiracles on the first three segments distant from the margin, those on

the following segments marginal, the last two visible from above. Legs very short, granulate, the

femora smooth on their inner face, the tibiee and tarsé slender. Surface granulate, the connexivum

smoother.

as in having a prominent longitudinal ridge on each side of the anterior part of the

pronotum.

anteriorly, and with a prominent longitudinal curved ridge on each side on the outer part of the disc, the

two inner callosities flat and without trace of ridges. Scutellum transversely wrinkled, and with a distinct

median ridge. Connexivum broad, rounded at the sides posteriorly. Terminal genital segment cordate ;

Of the twenty-eight described species of this widely distributed genus, one-half are

American, ten occurring within our limits, whence four others are now added.

Two inhabit the United States and four are recorded from South America, two of the

latter extending into our region. The genus was monographed by Dr. Bergroth in

1887, and since then ten other species have been added. ‘These insects are very like

Brachyrrhynchus, differing chiefly in the carinate anterior margins of the ventral

segments 3-5, the acute apex of the corium, and the flattened pronotum. ‘The median

portion of the apical margin of the fifth ventral segment is bisinuate in the females,

and truncate inthe males. In the females of WV. whleri, &c., the terminal genital segment

is notched or bilobed at the tip, and the lobiform lateral portions of the preceding

segment also vary a little in form according to the species.

We have not received a specimen of this insect, but Dr. Bergroth has communicated

a Mexican example (?) of it for examination, and from this our figure is taken.

N. ovatus is very like NV. dilatatus, but it has a longer, stouter, and more parallel apical

process to the head (reaching to near the apex of the first antennal joint), and less

acute antenniferous processes ; the upper surface is also more coarsely granulate and

the connexivum rugulosely punctured. The abdomen in the female is more rounded

at the sides than in the corresponding sex of NV. dilatatus, and has the terminal genital

segment bilobed at the apex.

The insect described by Dr. Bergroth (Ofv. Finsk. Vet.-Soc. Forh. xxix. p. 183)

about the Guatemalan record, or the insect would have been met with in the inter-

vening region; Dr. Bergroth, however, assures me that he has seen a Guatemalan

and the more or less rounded anterior angles somewhat prominent in front. Examples

occur of a ferruginous colour (W. rubiginosus, Bergr.). Dr. Bergroth has examined

one of the Chiriqui specimens and pronounced it to be N. punctulatus. In the single

(2) specimen from Mexico the post-ocular portions of the head are armed with a

‘Hab. Mexico (Mus. Berol.').

This insect is described as having the antenne rather stout, with the first joint

extending very little beyond the apex of the head, the second and third joints subequal,

the second slightly shorter than the first, the fourth shorter than the third; the

spiniform antenniferous processes short, parallel externally; the post-ocular spines

extending to beyond the eyes; the pronotum with the sides rounded and not sinuate ;

the corium with the apical margin bisinuate; the venter slightly convex, with the

posterior margins of segments 2-5 a little thickened. The body is elliptic in shape,

opaque, black, with the tarsi fulvo-ferruginous, the membrane lutescent at the base.

To judge from a drawing made for me by Fr. H. v. Zglinicka from the type ( @ ) in

the Berlin Museum, WV. distanti is very closely allied to NV. niger, Bergr.; but it

appears to be less coarsely granulate, and to have the basal joint of the antenne a little

longer, the connexivum more distinctly carinate towards the outer margin, and the

genital segments somewhat differently formed. Our figure is taken from this drawing.

and we also possess a male of it from Sallé. Very like NV. amplus, but relatively

narrower, especially in the female, the male with a conspicuous fold on the sixth

connexival segment, the pronotum more feebly sinuate at the sides. Also very like

N. uhleri, Bergr., but broader and a little more finely granulate, the terminal genital

segment of the female not deeply emarginate, the genital lobes shorter. Walker

confused two genera and several species under the name Mezira masta. The insect is

unknown to Dr. Bergroth.

12. Neuroctenus amplus, n.sp. (Tab. VII. fig. 23, 2.)

Ovate, depressed, dull, black, the abdomen piceous or fusco-ferruginous, the tips of the antenne and the coxe

and tarsi fulvous or ferruginous, the membrane with two luteous spots at the base; the upper surface

finely granulate, the connexivum very finely rugulose. Head somewhat rounded at the base; the apical

process stout, long, reaching as far as the apex of the first antenna] joint, slightly notched at the tip ;

the spiniform antenniferous processes acute, moderately long, subparallel externally ; the post-ocular

portions armed with a rather prominent spine, which projects outwards as far as or to a little beyond the

eyes; antenne moderately stout, rather long, joints 1-3 increasing in length, 1 and 4 subequal, 4 ovate.

Pronotum short, emarginate in front, the sides feebly sinuate. Corium acute, the apical margin bisinuate.

Connexivum broad, rounded at the sides posteriorly in the female; in the male with the fifth and sixth

segments obliquely narrowed, and their outer apical angles rounded externally. Beneath dull and very

finely rugulose. Venter flattened ; fifth ventral segment with the median portion of the apical margin

truncate in the male and bisinuate in the female. Terminal genital segment of the female unemarginate

at the apex, the lobes of the preceding segment broadly rounded. Femora granulate.

Length 6,9,;-84, breadth 3-4 millim. (6 @.)

Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith).

One male and three females. Very like WV. dilatatus, Bergr., but with a stouter and

more cylindrical apical process to the head, and differently formed antenne, joints

1-3 increasing in length (long and subequal in WN. dilatatus), 1 short and not longer

than the apical process. NV. whleri is also an allied form, but it is narrower and has

shorter antenne, with joints 1-3 subequal in length. This last-mentioned species

(a female only of which is before me) is compared by Dr. Bergroth with W. simplex,

Uhler, and NV. punctulatus, Burm.

13. Neuroctenus uhleri. (Tab. VII. fig. 24, 2.)

Neuroctenus uhleri, Bergr. Wien, ent. Zeit. xiv. p. 169 (¢ 2) (1895) *.

Hab. Mexico, Orizaba (Bilimek, in Mus. Vind. Ces.1),

This species is oblong in shape, and pitchy-black in colour, the abdomen ferruginous,

with the ventral surface yellowish in the middle; the antenne are rather short, with

NEUROCTENUS.—ANEURUS. 118

joints 1-3 subequal in length and 4 shorter than 3; the post-ocular spines extend

outwards to a little beyond the eyes; the pronotum is feebly sinuate at the sides; the

connexivum is rather narrow and faintly longitudinally carinate towards the outer

margin. One of the types, a female, has been examined ; it has the terminal genital

segment deeply notched at the apex, as may be seen by a reference to our figure.

14. Neuroctenus subparallelus, n.sp. (Tab. VII. figg. 25, 2; 25a, antenna.)

2. Elongate, narrow, parallel or subparallel, dull, black, the tips of the antenne, the coxe and tarsi, and

sometimes the apical margins of the connexival segments, more or less ferruginous, the membrane with

two obscure luteous spots at the base; the upper surface granulate, the connexivum finely rugulose.

Head somewhat rounded at the base; the apical process long and stout, extending fully as far as the apex

of the first antennal joint, notched at the tip; the spiniform antenniferous processes short; the post-

ocular portions armed with a short spine; antenne short and stout, joints 1-3 subequal in length, 4 ovate,

stouter and considerably longer than 3. Pronotum trapezoidal, short, sinuate at the sides, the anterior

angles rounded. Corium acute at the tip, the apical margin feebly bisinuate. Connexivum narrow,

rounded at the sides posteriorly. Beneath dull and rugose; the venter rather convex, the segments each

with a smooth, narrow, elongate-triangular spot in the middle behind; the fifth segment with the median

portion of the apical margin feebly bisinuate. Terminal genital segment unemarginate at the apex.

Femora granulate.

Length 53-6}, breadth 13-2 millim.

Hab. Muxico, Atoyac in Vera Cruz (Schumann); Guatemaua, Senahu and Cubilguitz

in Vera Paz, El Tumbador (Champion).

A single specimen from each locality. Belongs to Dr. Bergroth’s first section of the

genus, but differs from all the species described in his Monograph by its narrow, parallel

shape, in connection with the short, stout antenne, with long apical joint, and the rather

convex, rugose venter.

This insect is nearly allied to NW. longulus, Bergr., from Cayenne *; but it is smaller

and less robust, with the apical joint of the antenne longer than the third, the

post-ocular portions of the head armed with a short tooth, &c. The specimen from

Cubilguitz is figured. .

Hemipt. iii. pp. 140, 146 ; Bergroth, Verh. zool.-bot. Ges. Wien, xxxvi. p. 58 (1886).

The species of this genus are very similar in appearance, but, as a rule, easily

distinguishable by the structure of the head and antenne, and the form of the terminal

genital segment in the males. They may be readily recognized by their very flattened

form, semicircular scutellum, membranous, undefined corium, the membrane without

distinct nervures, and short wings. Dr. Bergroth (op. cit.) has characterized five

neotropical species (one of which, A. westwoodt, Bergr., had been previously described

by Walker under the name of Crimia marginalis); but of these one only appears to

inhabit Central America, whence five are now recorded.

Ovate, rather elongate, shining, piceous or castaneous, the abdomen above and beneath rufo-ferruginous, with

the connexivum usually darker. Head transversely rugulose, with obtuse antenniferous tubercles and

short post-ocular spines ; antenne considerably more than twice the length of the head, joint 1 moderately

Length 4, breadth 17 millim. (9.)

Hab. Panama, Volcan de Chiriqui (Champion).

Found in numbers at Capetillo, sparingly in Chiriqui. The variety (?) is represented

by a single specimen. This species is allied to A. (Crimia) marginalis, Walk. (=west-

woodi, Bergr.), from Colombia; but differs from it in having joints 2—4 of the antenne

much more slender, and 4 fusiform, and the pronotum smoother. A. (Crimia) simulans,

Walk., from Brazil, of which there are numerous specimens in the British Museum, is

also very like A. tenuicornis, but it is smaller and narrower, and has stouter antennae,

the apical joint being fusiform in both species. The small variety (?) is very like

A. simulans, but it is broader and not so smooth, and has more slender antenne.

A, simplex, Uhler *, from New England, is also described as having long and very

slender antenne, but with the third joint less than one-half the length of the fourth ;

it is, however, more coarsely granulate than A. tenuicornis. A. flavomaculatus, Dist.,

from Ecuador, has the antenne stouter, the pronotum more rugose, the antenniferous

tubercles less obtuse, and the elytra broadly yellowish at the base. Capetillo specimens

are figured. The insect is unknown to Dr. Bergroth.

ANEUROSOMA, n. gen.

Scutellum equilaterally triangular, as long as the pronotum. Pronotum truncate at the base. Abdomen (?@ )

very broadly truncate-emarginate at the apex. The other characters as in Aneurus.

The single species referred to this genus has all the characters of Aneurus, save the

form of the scutellum. It also resembles Jsodermus, Er., but has a rostral channel.

* The North-American A. septentrionalis, Walk., has rather stout antenne, but with the joints of about the

same length as in A. simplex,

rugulose, with a smooth callosity on each side between the eyes; the antenniferous tubercles rounded ;

the post-ocular portions tumid and obtuse, subtruncate behind ; antenne more than twice the length of

the head, joint 1 stout, obovate, 2-4 slender, 2 and 3 equal in length, becoming thinner towards the base,

each considerably longer than 1, 4 fusiform, about as long as1 and 2 united, pilose at the tip. Pronotum

transverse, trapezoidal, emerginate at the sides and in front; the anterior and posterior lobes separated

by a deep groove, each smooth and callous towards the sides, the anterior lobe also with two smooth

callosities on the disc, the other portions of the surface finely rugulose and minutely granulate. Scutellum

rugulose, smoother in the centre. Corium subopaque. Connexivum almost smooth, except along the

margin. Abdomen broadly truncate-emarginate at the apex, the first genital segment short and very

wide. Legs moderately long, the femora clavate and finely granulate.

A widely distributed genus containing seven described species*. The type,

H. pusillus (Fall.), of Europe and N. Africa, has 5-jointed antenne; but some

authors, including Laporte, give the antenne as 4-jointed, the division between the

fourth and fifth joints being not very distinct ; others (Douglas and Scott +) mention

six joints, the minute jointlet at the base of the third being counted as a true joint.

The ventral sutures are indistinct or obliterated in some of the species. The tarsi

are 2-jointed. In H. major, H. leviventris, &c., the males have the venter broadly

flattened in the middle, and in the same sex of H. sulcatus the intermediate femora

are armed with a short tooth. All the Central-American Hebride seen by me

are winged.

slightly infuscate ; and the pronotum is somewhat feebly constricted at the sides, the

two lobes not being sharply separated.

H. parvulus, Stal, from Rio Janeiro (the type of which is before me), is a very

closely allied form ; but it has a rather more elongate basal joint to the antennae, the

two lobes of the pronotum more distinctly separated, the wedge-shaped mark on the

_clavus shorter, the white streak between the nervures of the corium indistinct, and

the whitish marks on the membrane less conspicuous. . consolidus was found in

plenty in the island of Grenada by Mr. H. H. Smith.

5. Hebrus leviventris, n.sp. (Tab. VIII. fig. 5.)

Rather elongate, narrow, fuscous or rufo-fuscous, the pronotum with the anterior margin and a narrow space

down the middle indeterminately fulvous or flavous; the under surface testaceous or flavous, with the

sides of the venter broadly blackish ; the antenne testaceous, paler at the base; the coxe, trochanters,

and legs flavous, the knees slightly darker; the elytra smoky-brown, with a long, wedge-shaped,

silvery-white mark at the base of the clavus and a long narrow pallid streak between the nervures of

the corium, the latter black at the apex, the membrane with one or two obscure luteous oval spots

along the middle, these being sometimes connected; the body, legs, and antenne finely pubescent.

Head without distinct median groove; antenne 5-jointed, 3-5 very slender, 2 a little shorter than 1,

3 elongate, 4 and 5 subequal in length, together slightly longer than 3. Pronotum deeply constricted

at the sides, and with a fine transverse groove before the base, the anterior and posterior lobes sharply

separated, the latter depressed along the middle in front; the surface with scattered punctures, the line

of demarcation between the two lobes indicated by a few deeper impressions. Venter smooth and

shining, the sutures between the segments almost obliterated.

3. Second and third ventral segments depressed in the middle.

Length 14-22 millim.

Hab. Panama, Tolé (Champion).

This species resembles Merragata leucosticta in colour, but it is more elongate, and

has 5-jointed antenne; the pronotum is still more deeply constricted at the sides,

with the two lobes more sharply separated and the posterior lobe depressed along the

middle. The nine specimens obtained are in a bad state of preservation, one only

having the antenne entire.

6. Hebrus sulcatus, n. sp. (Tab. VIII. figg. 6, ¢; 6a, antenna; 64, inter-

Three males and two females. This species may be known by the deeply, longi-

tudinally sulcate disc of the pronotum, in connection with the long basal joint of the

antenne, the rather elongate body, &c. The apical two joints of the antenne are

together much longer than the third. The rostral groove is limited on each side by a

prominent ridge, which is continued on to the first ventral segment.

Hab. Mexico, Chapultepec (Bilimek, in Mus. Vind. Ces.) —Hawatian Is.?

One specimen only of this peculiar little species has been seen; it agrees perfectly

with the Hawaiian example (2) in the British Museum. The very short antenne,

with joints 1-3 subequal in length and the fourth longer, stouter, and fusiform,

separates it at once from all the other members of the family described here. It is

probable that the species has been introduced into the Hawaiian Islands.

the narrow space between the nervures pale brown, the membrane with several indistinct pallid spots ;

the antenne obscure testaceous; the rostrum, legs, cox, and trochanters flavo-testaceous; the body,

legs, and antenne clothed with rather long, fine hairs. Head with a distinct median groove; antenne

4-jointed, 3 and 4 very slender, 1 and 2 subequal, 3 much longer than 2, 4 much longer than 3,

Pronotum deeply constricted at the sides, the disc without median groove, the surface with scattered

punctures. Scutellum with indications of a median ridge, subtruncate behind.

Length 12 millim. (2.)

Hab. Guatemata, San Gerdnimo (Champion).

Three examples. Shorter than Hebrus consolidus, Uhler, the pronotum much more

strongly constricted at the sides, the silvery-white wedge-shaped mark on the clavus

shorter, the corium without a white streak, the membrane with indistinct paler spots,

the pubescence longer, the antenne 4-jointed.

3. Merragata brevis, n. sp. (Tab. VIII. fig. 9.)

fulvous median line; the pronotum more or less mottled with fulvous or rufo-fulvous, the anterior —

margin constantly fulvous; the elytra with a whitish, wedge-shaped, evanescent mark at the base of

the clavus, and a pallid streak between the nervures of the corium, the nervures themselves black at the

apex, becoming brownish or fulvous towards the base, the membrane fuscous, usually with some paler

spots; the antenne testaceous or rufo-testaceous, with joints 1 and 2 sometimes darker at the apex;

the under surface black, with a greyish pruinosity, the genital segments flavous in the male; the

This is apparently the commonest species of the family in Central America; it was

found in plenty in the vicinity of the city of Guatemala. The insect is very like

Hebrus concinnus, Uhler; but it has 4-jointed antenne, and the head is constantly

rufescent at the sides between the eyes. The form of the antenne seems to be quite

constant. The venter is similarly formed in both sexes. A specimen from Guatemala

city is figured.

Two fully-developed examples (2?) were found by Mr. Smith at Teapa. The

fourteen specimens, including both sexes, found by myself in the vicinity of the city

of Panama are without wings and have abbreviated elytra, the membrane being

undeveloped. They do not differ from the Antillean specimens named UV. bisignata

by Prof. Uhler, which fit the description of VM. mulsanti, Buch. White. I have seen

a winged specimen from Texas (Belfrage).

In fresh specimens of this insect the femora above, the hind tibize within and without,

and the intermediate tibize externally, are set with long blackish spines or sete, the

intermediate tibie have some very long hairs on the inner side near the apex, and the

anterior and intermediate femora are armed on the inner side with a series of very

short, fine spines, with longer spines intermixed.

Fam. HYDROMETRIDZ.

The three subfamilies of Hydrometride are all represented in Central America: the

Hydrometrine by three, and the Veliine and Gerrine by numerous species. The

Veliine include many species of Rhagovelia and Microvelia, and afew of Velia. With

one exception, Trochopus salinus, all the Central-American Hydrometride known to

me live upon the surface or margins of freshwater pools or streams.

A genus containing about a dozen described species, and generally distributed.

They are slender, stick-like, sluggish insects, and have the habit of walking about

slowly on the surface of the water in sheltered spots. Five American species have

been described and one other is now added, but it is possible that these are not alli

specifically distinct. The Central-American forms may be separated thus :—

Rostrum not extending beyond the eyes; antennz.about two-thirds the length

of the body.

ocular portion, the head moderately dilated at the apex and slightly

thickened at the base . . . . . ww ee ee ee ee Carta, Gur.

A winged female and a brachypterous male from the State of Panama agree

sufficiently well with Guérin’s description of H. caraiba. They have the ante-ocular

portion of the head nearly or quite two and one-half times longer than the post-ocular

portion ; the rostrum does not extend backwards beyond the eyes; the pronotum has

a whitish or grey, black-bordered median line, and its surface is very distinctly

punctured ; the metanotum is as long as the pronotum; the hind coxe are separated

from the intermediate coxe by a space about one and a half times greater than that

HYDROMETRA. 125

between the anterior and intermediate coxe; the abdomen is very elongate; the

antenne in the male are about two-thirds the length of the body, with joint 3 three

times as long as 2, and 4 one-third longer than 3; the elytra in the winged female

nearly reach the apex of the fourth dorsal segment. The male measures 133 (head 4,

abdomen 51), the female 16 (head 44, abdomen 64) millimetres in length ; Guérin’s

single specimen was considerably more elongate. H. metator, Buch. White, from the

Amazons, must be a very closely allied form; it (¢ ) is described as having the antenne

as long as the body.

2. Hydrometra lentipes, n. sp.

Black or pitchy-black, with a bluish-grey pruinosity, the base of the head and of the first joint of the antenne

rufescent ; the legs brownish, the coxe and trochanters paler; the connexivum sometimes with a fulvous

stripe ; the elytra pale brown, with blackish-brown nervures; the pronotum with a greyish-white median

line; the under surface (in fresh specimens) clothed with greyish-white pubescence. Head considerably

thickened at the base, as well as at the apex, appearing very narrow before and behind the eyes, the

ante-ocular portion about twice as long as the post-ocular portion ; rostrum not reaching beyond the eyes ;

antenne two-thirds the length of the body, joint 2 about twice as long as 1,3 nearly three times as

long as 2, 4 nearly twice as long as 3. Pronotum with a few scattered punctures and a depressed

median line.

Hab. Guatemata, Rio Naranjo and Paraiso (Champion).

An apterous pair and a winged male, all from the low country bordering the Pacific

Ocean. Very lke the insect here referred to H. caraiba, but less elongate and

considerably smaller ; the head narrower, more dilated in front, more thickened at the

base, with the ante-ocular portion relatively shorter; the abdomen less elongate.

H. lentipes is also very like the Palzearctic H. stagnorum (Linn.), but it has a differently

shaped head, a shorter rostrum, and longer antenne. ‘The head is thickened at the

base in all three examples. /. lineata, Say, is probably a nearly allied form, but

specimens of it are not available for comparison.

specimen and mentioned by Buchanan White) are probably present in the winged form

only. This insect is closely allied to the Palearctic H. stagnorum (Linn.), differing from

it in colour and in having shorter antenne, with a relatively shorter third joint. Both

species have the rostrum extending almost to the base of the head. The antenne are

only about half the length of those of H. caraiba. The elytra in the winged female

from Santarem nearly reach the apex of the fourth dorsal segment. HH. argentina,

Berg, is coloured like H. mensor, but it is described as having the antenne formed as

in H. stagnorum. Some North-American specimens in the British Museum, received

from Doubleday, are very like H. mensor.

Hab. GuateMa.a, Duefias (Champion).

One specimen only of this handsome little species was obtained. It approaches

M. modesta, Uhler, from the Island of Grenada, but has shorter legs. The elytra are

somewhat immature and creased, but they appear to have each five silvery-white spots

or streaks. The head is without an impressed median line.

M. mimula, Buch. White, from the Amazons, and J. signata, Uhler, from Lower

California, are also allied forms.

7. Microvelia rufescens, n. sp. (Tab. VIII. fig. 18, apterous specimen.)

Apterous form. Obovate, rather narrow, convex beneath; fuscous of fusco-ferruginous, the pleura and sides

of the venter blackish, the connexivum above and beneath obscure ferruginous; the antenne, coxe,

trochanters, and legs testaceous or flavo-testaceous; the upper surface thickly and uniformly clothed with

brownish pubescence ; the under surface greyish-pruinose and clothed with pallid pubescence; the legs

and antenne very finely pubescent. Head with indications of a very fine impressed median line in front ;

antenn more than half the length of the body, slender, joint 2 shorter than 1, 3 very slender and nearly

twice as long as 2, 4 slightly longer than 3, pointed at the tip. Legs moderately long, comparatively

stout, the tibiz included.

Length 23-23, breadth (of the abdomen) 1-13 millim.

Hab. GuateMALA, Duefias (Champion).

Three specimens, apparently two males and one female. ‘The supposed female is

more convex than the others, and has the short genital segments not visible from

beneath. In the males(?) the genital segments are narrowly exposed above and

beneath. This insect has stouter tibie than any of the other Microvelie here described,

and the body is obovate, instead of fusiform, the species approaching in this respect the

European M. pygmea (Duf.).

8. Microvelia setipes, n.sp. (Tab. VIII. fig. 19, apterous ¢.)

Apterous form. ¢. Elongate, narrow, narrowing in front and behind, black or blackish-fuscous, the pronotum

with a transverse rufo-fulvous band in front; the connexivum, the pleura, the middle of the meso- and

metanotum and also of the dorsal segments of the abdomen, and the venter, except at the sides, obscure

ferruginous; the rostrum flavous, with the apical joint black; the coxe and trochanters flavous; the legs

brownish, with the femora flavous or testaceous; the antennee fuscous, with the base of the first joint

Hab. Mexico, Chapultepec and Orizaba (Bilimek, in Mus. Vind. Ces.).

Three males and a single gravid female, evidently belonging to the same species.

Differs from all the other Central-American species described here in the setose posterior

tibize, a character common to WM. longipes, Uhler, and other Antillean forms.

Neovelia, Buchanan White, Journ. Linn. Soc., Zool. xiv. p. 487 (1879).

Of the ten described species of this genus, all but three are American ; eight others

are now added from within our limits. -~&hagovelia is well characterized by the

3-jointed tarsi *, and the long, deeply-fissured, terminal joint of the intermediate tarsi.

In this fissure there is a series of long ciliated hairs, arising from a common stem,

which are probably extended, fan-like, when the insect moves about on the surface of

the water; these hairs are sometimes partly extended in dried specimens, but they are

usually hidden within the fissure. All the true Rhagovelie live upon the surface of

fresh water, the single described salt-water form, &. plumbea, Ubler (=Trochopus

marinus, Carp.), from the Antilles and Florida, belonging to Trochopus, to which a

second species is here added. In the apterous specimens the pronotum is usually

extended backward so as to cover, and to appear fused with, the mesonotum ; but in

R. tenuipes (as in the two species of Zrochopus) there is a well-defined suture across the

pronotum towards the apex, reducing it to a short lobe. In the winged examples the

backward growth of the pronotum is much more pronounced, the posterior portion

being often produced into a long spiniform process. In two of the Central-American

species, as well as in the Antillean f. elegans, Uhler, the posterior tibie are armed

with a long hook at the apex.

The American species known to me may be thus differentiated :—

a. Posterior tibiz with or without a straight spur at the apex.

a’, Penultimate joint of the intermediate tarsi not or very little longer

than the apical joint; elytra extending to a little beyond the

abdomen, with regular longitudinal nervures ; pronotum (in the

winged forms) acute or produced into a spiniform process behind ;

abdomen moderately long.

a', Posterior femora more or less incrassate, at least in the ¢.

a'", Intermediate femora not constricted at the middle.

a‘. Posterior femora greatly incrassate and dentate, and the

posterior tibiz also conspicuously dentate or denticulate,

RHAGOVELIA. 133

1. Rhagovelia crassipes, n. sp. (Tab. VIII. figg. 20, apterous ¢, from

beneath ; 21, apterous @.)

Winged form. Elongate, robust, brownish-black, the front of the head and the posterior margin of the

pronotum, and sometimes a narrow evanescent median line on the disc of the latter anteriorly, obscure

ferruginous ; the pronotum with a transverse fulvous fascia in front, this becoming whitish at the sides ;

the venter, except at the sides, and the conuexival margins fulvous; the pleura and sides of the venter

bluish-grey ; the antenn nigro-fuscous, testaceous at the base; the legs fuscous or nigro-fuscous, much

paler beneath, the trochanters and coxee, and the base of the anterior and hind femora testaceous; the

elytra blackish-brown, with black nervures ; the entire body, legs, and antenne clothed with short, fine,

brownish or pallid pubescence, the head, pronotum, and sides of the body sparsely, the legs, and joints 1-3

of the antenne thickly, clothed also with long hairs, the legs and joints 1 and 2 of the antennez with

scattered sete. Head with a smooth impressed median line; antenne moderately long, joint 1 rather

more than one-half longer than 2, 3 a little shorter than 2, 4 shorter than 3, pointed at the tip. Pro-

notum produced behind into a long, raised, spiniform process, which is armed beneath at some distance

pair comparatively clongate ; intermediate tarsi with joint 2 slightly shorter than 3.

dS. Posterior femora enormously incrassated, armed with numerous short teeth, the innermost of these arranged

in two regular rows, and with one longer tooth towards the base and three or four others towards the

apex; posterior tibia bowed inwards to beyond the middle and curved outwards thence to the apex,

shortly denticulate on their inner edge, and armed with one long tooth at about one-third from the apex,

a shorter one close to it, one near the apex, and another at the apical angle; posterior coxe and

trochanters very stout, the coxe rather narrowly separated, the trochanters obsoletely denticulate beneath.

Metasternum with a smooth, rufous, tuberculiform prominence in the middle behind. Ventral segments

1-3 keeled down the centre. Sixth ventral segment arcuate-emarginate at the apex, the sides of this

segment, like those of the genital segments, thickly clothed with bristly hairs. Sixth dorsal segment

truncate at the apex.

Q. Posterior femora moderately incrassate, slightly hollowed on the inner side towards the apex, armed with

numerous short teeth, which extend from the middle to the apex, and with one long slightly curved tooth

a little before the middle ; posterior tibie straight, shortly denticulate within, and with a short straight

tooth at the apical angle ; posterior coxe widely separated. Sixth dorsal segment rounded at the apex.

Length 6-7, breadth (of the pronotum) 23-2? millim.

Apterous form. Fusiform, the pronotum abbreviated and rounded behind, the sutures and the sides of the

dorsal abdominal segments grey or bluish-grey, the latter inclining to ferruginous down the centre.

Hab. Panama, Tolé and Pefia Blanca (Champion).

Found in plenty on the surface of the rivers draining the Pacific slope. Five only

of the specimens are winged. ‘This species is well characterized by the enormously

thickened hind femora and the bowed hind tibie in the male sex, both femora and

tibie being armed with numerous teeth. The hind femora of the female are formed

somewhat as in the male of &. armata. The oblique ridge on each side of the meso-

sternum, extending from the intermediate to the anterior coxe, is very prominent. In

one of the apterous males from Tolé the hind legs, the metasternum, and the base of

the abdomen are formed exactly as in the females: it is probably a monstrosity.

2. Rhagovelia varipes, n.sp. (Tab. VIII. fig. 22, apterous ¢.)

Apterous form. 3. Elongate, moderately robust, fusiform, black, the abdomen piceous at the apex above, the

base of the antennz, the prosternum, the cox, the trochanters (the apex of the intermediate pair

excepted), the anterior femora with about the basal half above and beneath, the intermediate femora at

the base beneath, and the posterior femora at the base, beneath, and within, more or less flavous; the

pronotum with a transverse fascia in front, the connexivum, and the venter, except at the sides anteriorly

fulvous; the body clothed with fine brownish pubescence, the head and the sides of the pronotum and of

the terminal abdominal segments with long hairs; the antenne clothed with fine hairs, the two basal joints

also with scattered sete; the legs thickly clothed with long hairs and scattered seta. Head with a

smooth impressed median line; antenne with joint 2 about one-half the length of 1 (the other joints

broken off). Pronotum abbreviated and rounded behind, with indications of a median ridge anteriorly.

Abdomen gradually narrowing from the base; the first and second ventral segments strongly, longitu-

dinally carinate down the middle, the sixth segment deeply triangularly emarginate at the apex, leaving

the first genital segment exposed. Anterior tibie slightly hollowed at the apex beneath. Intermediate

tarsi with the second joint slightly longer than the third. Posterior femora greatly incrassate, armed

with numerous teeth, which are placed in two rows along the centre, those of the upper row unequal in

length, there being three longer teeth towards the middle and two beyond it; posterior titi denticulate

and strongly sinuous, the teeth along the apical third slightly longer than the others, the apex unarmed.

Length nearly 6, breadth 13 millim.

Hab. Mexico (Bilimek, in Mus. Vind. Ces.).

One specimen. Allied to &. crassipes, but differing from the apterous male of that

species in the less thickened posterior femora, the posterior tibie without long teeth at

the apex, the second joint of the intermediate tarsi longer, the sixth ventral segment

triangularly emarginate at the apex, &c. The more thickened posterior femora and the

sinuous posterior tibie separate 2. varipes from the males of 2. armata, R. distincta, &c.,

the last-mentioned character distinguishing it from 9. femoralis. Also very like

&. collaris, but larger and more elongate, with longer legs and antenne, the anterior

tibie undilated in the male, &c.

8. Rhagovelia femoralis, n. sp. (Tab. VIII. fig. 23, apterous 3.)

band on the pronotum just before the apex, the front of the prosternum, the anterior coxe and trochanters,

the anterior femora broadly at the base and in great part beneath, the middle coxe, the hind coxe and

trochanters, the hind femora within, beneath, and at the base, and the venter in the middle at the apex,

flavous or fulvous; the pleura and the sides of the abdomen bluish-grey; the body, legs, and antenne

clothed with short, very fine, brownish pubescence, the sides of the body, the head, the two basal joints

of the antenne, and the legs clothed also with long hairs and sete. Head with a smooth impressed

median line; antenne comparatively short, joint 1 about twice as long as 2, 2-4 subequal in length,

4 fusiform, pointed at the tip. Pronotum abbreviated and rounded behind. Legs stout, the middle pair

very long, the hind pair comparatively short ; posterior femora enormously incrassated, armed with two

rows of rather long teeth, extending from about the basal third to near the apex, and with one much

longer tooth at the basal third ; posterior tibie almost straight, denticulate within, and armed with one

long tooth at some distance from the apex and another at the apical angle; posterior trochanters denti-

culate beneath ; intermediate tarsi with joint 2 slightly shorter than 3. Ventral segments 1-5 with a

median ridge, which becomes evanescent posteriorly.

Length 43, breadth (of the pronotum) 13 millim.

Hab. Panama, Pefia Blanca (Champion).

One example. Allied to #. crassipes, but much smaller, with relatively shorter

hind legs, the armature of both femora and tibie very different, the antenne shorter,

the intermediate tibie relatively shorter, the metasternum without tubercle in the

male, &c. #. collaris (Burm.), from the Antilles and South America, one of the types

of which is before me, is very like the present species; but it has the anterior

the basal half of the anterior femora, the hind femora at the base, within, and beneath, the connexivum,

the last three ventral segments broadly in the middle, and the genital segments beneath, flavous or fulvous ;

the pleura and sides of the abdomen bluish-grey ; the elytra blackish-brown, the nervures darker; the

head and pronotum somewhat thickly clothed with short yellowish pubescence, the head and propleura

with a few long bristly hairs; the costal margins of the elytra, the sides of the body, the legs, and

antennew pubescent, the two basal joints of the antenne, the margins of the genital and sixth connexival

segments, and the legs clothed also with long scattered sete. Head with a smooth impressed median

Hab. Mexico (Mus. Berol.1: 3; Mus. Vind. Ces., ex coll. Signoret?: 2).

Burmeister’s diagnosis of this species is quite inadequate, and a fresh description is

given from one of his types, a male, and from a second specimen ( 2 ) belonging to the

Vienna Museum. RR. armata is perhaps nearest allied to BR. femoralis, differing from

it in the more elongate body, the longer legs and antenne, the less incrassate posterior

femora in the male, the hind tibiz without long teeth in this sex. The partly flavous

posterior femora, the depressed base of the venter in the male, &c., separate it from

R. distincta. The apterous female from the Signoret collection is figured *.

in the males the terminal ventral segment in the middle and the underside of the first genital segment,

more or less flavous; the pleura and under surface bluish-grey; the body, legs, and antenna very finely

pubescent, and also clothed (the two apical joints of the antennz excepted) with long scattered sete, the

pronotum usually with a transverse patch of greyish or silvery pubescence on each side in front. Head

with a smooth impressed median line; antennez moderately long, joint 1 about one-half. longer than 2,

2 and 3 equal in length, 4 shorter than 3, stout, fusiform. Pronotum with a distinct median ridge, and

produced behind into a spiniform process, the surface sparsely and finely punctured. Legs long and rather

slender, the hind tibiee with a very short indistinct tooth at the apex; intermediate tarsi with joints

2 and 3 subequal in length.

¢. Anterior tibiz dilated in their apical half; posterior femora moderately incrassate, armed on the inner

side with a long, partly flavous, tooth at about one-third from the base, and with a row of short teeth

extending thence to the apex (in some of the well-developed apterous examples also closely and finely

denticulate along the basal third); posterior tibie finely denticulate and slightly sinuous within. Pronotal

spine short. Sixth ventral segment broadly flattened along the middle and feebly arcuate-emarginate at

the apex.

9. Posterior femora not stouter than the intermediate femora, armed with a very long, acute, blackish tooth

at about the middle, and very finely denticulate thence to the apex; posterior tibie straight, obsoletely

denticulate within. Pronotal spine very long, stout, and raised, armed with a strong tooth at the

base beneath.

Length 5, breadth (of the pronotum) 14-1? millim.

Apterous form. § 2. Fusiform, the pronotum abbreviated and rounded behind; the abdomen metallic green

above, with a stripe of greyish pubescence running down each side of the dorsal surface; the connexivum

very broad in the females, extending inwards and overlapping the dorsal surface of the abdomen, the two

portions nearly or quite meeting along the median line.

at most, flavous at the base; the sixth ventral segment broadly flattened, the flattened portion limited on

each side anteriorly by a short, angular, longitudinal ridge.

Hab. Mexico, Ciudad in Durango 8100 feet (Forrer).

Of this species we have received a winged pair from Orizaba, as well as numerous

apterous specimens and nymphs from the same locality ; there are also three winged

Mexican examples (two males and one female) of it in the Vienna Museum *, one of

them being from the Signoret collection. It is the Velia distincta of Walker's

Catalogue. The form treated as a variety is represented by five females and one

male, all of which are apterous. The great difference in the form of the pronotal

spine amongst the winged specimens is perhaps a sexual character. In some of the

males the posterior femora are more strongly incrassate, with the basal third closely

and distinctly denticulate within; the females have the single long tooth more distant

from the base, and the outer teeth very short and fine. The apical joint of the antenne

is a little stouter than in R.armata. A. angustipes, Uhler, from the island of Grenada,

is an allied form, but it has more slender hind femora. It is possible that &. distincta

may prove to be referable to R. obesa, Uhler, but the description of the latter is too

incomplete for identification. Orizaba specimens are figured, showing the different

forms.

pronotum microscopically pubescent, the pronotum greyish-pruinose at the sides in front, and clothed

laterally with a few bristly hairs, the sides of the body sparsely pubescent, the sixth and genital segments

fringed laterally with bristly hairs; antenne and legs finely pubescent, the femora, tibice, and the two

between this and the apex, these latter diminishing in length outwards ; posterior tibise straight, obsoletely

denticulate towards the base, and with a very short straight tooth at the apical angle; intermediate tarsi

with joint 2 shorter than 3.

injured during the earlier stages of the insect; but as the constriction is precisely

similar in both legs, this cannot be the case. The hind femora, too, are abnormal in

form, being hollowed on the inner face towards the base and apex, appearing bisinuate

within. The pronotum is conspicuously punctured.

7. Rhagovelia tenuipes, n.sp. (Tab. VIII. figg. 29, winged ¢ ; 30, apterous 9 .)

Winged form. Moderately clongate, black, the legs with an seneous lustre, the base of the antenne pale flavous,

the pronotum with a narrow fulvous transverse mark in front, the anterior and hind coxe and trochanters

more or less flavous; the pleura and under surface bluish-grey; the body, legs, and antenne clothed with

very fine brownish pubescence, and also (the apical two joints of the antenne excepted) with a few long,

scattered sete. Head with a smooth impressed median line; antennz long and slender, joint 1 nearly

twice as long as 2, 2 and 3 equal in length, 4 considerably shorter than 3, curved, pointed at the tip.

Pronotum with the posterior portion obtuse behind, the surface with very fine scattered punctures. Elytra

extending to far beyond the apex of the abdomen, the neuration irregular. Abdomen short. Legs very

long and slender, the hind tibie unarmed at the tip; intermediate tarsi with joint 2 considerably longer

than 3.

158 HEMIPTERA-HETEROPTERA.

Apterous form. Subfusiform (¢), oblong-ovate (2); the pronotum abbreviated and rounded behind, the

anterior lobe separated by a distinct suture; the upper surface uniformly clothed with brownish pubes-

cence, the pronotum with greyish pubescence on each side in front.

3 2. Posterior femora comparatively slender, not stouter than the intermediate femora, armed with a long,

slender, acute tooth at about the middle, and with a row of very short teeth extending thence to near the

apex ; posterior tibiz unarmed on their inner edge.

Length of the winged male 4; breadth of the apterous female 13, of the pronotum of the winged male 13 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith).

One winged male example, one apterous female, two immature apterous males, and

two nymphs have been received of this species, which differs from all others of the

genus here described in the long, slender, posterior femora in the male—these being

similarly formed in both sexes, and having a slender prominent tooth,—the slender

antenne, &c. &. tenuipes is nearest allied to &. angustipes, from Grenada and

St. Vincent *, it having the armature of the posterior femora similar; but has longer

legs and antenne, and a much longer penultimate joint to the intermediate tarsi.

The sete on the two basal joints of the antenne are few in number. ‘The neuration

of the elytra is different from that of the allied species, the median longitudinal

nervure being irregular, and at about the middle connected with the inner and costal

nervures by more numerous transverse veins. The apterous female specimen has the

thoracic sutures formed as in the genus Trochopus—e. g., the pronotum is reduced to

a short lobe, and the larger posterior portion becomes mesonotum. The abdomen is

short in both forms.

8. Rhagovelia uncinata, n. sp. (Tab. IX. figg. 1, apterous ¢, from beneath ;

2, winged 9; 24a, elytron.)

Winged form. Moderately elongate, nigro-fuscous or rufo-fuscous, the front of the head, the base of the

antennee, the pronotum with a broad band in front, the lateral and posterior margins, and an evanescent

median line, the connexival margins broadly, and the under surface, flavous or testaceous, the venter

sometimes with a fuscous stripe on each side; the legs black above, flavous beneath, the anterior femora

at the base above, the posterior femora at the base and within, and the coxe and trochanters also more or

less flavous ; the elytra blackish-brown; the body, legs, and antenne finely pubescent, the head, the sides

of the body, and the three basal joints of the antennz somewhat thickly clothed with long hairs, the legs

and joints 1 and 2 of the antenne also with scattered sete. Head with a smooth impressed median line;

antenne rather slender, joint 1 one-half longer than 2, 2-4 decreasing in length, 4 pointed at the tip.

Pronotum sparsely punctured, the posterior portion triangular, obtuse at the apex. LElytra extending as

far asthe apex of the terminal process of the abdomen. Terminal genital segment in both sexes produced

into a sharp spine at the apex. Legs rather slender; the posterior tibie armed with a long, slender

hook at the apex in both sexes ; the intermediate tarsi with joint 2 much shorter than 3.

do. Posterior femora moderately incrassate, armed with seven or eight acute, curved teeth, the two inner ones

much longer than the others and widely separated (one at the middle, and one at about the basal third),

the two or three apical ones very short; posterior tibie finely and obsoletely denticulate on their inner

edge, the denticulation becoming more distinct towards the base.

¢. Posterior femora less thickened, with the teeth usually a little shorter.

Apterous form. 3 9. Fusiform; the pronotum abbreviated and rounded behind, bordered with flavous all

round, the mesonotum also bordered with flavous behind; the abdomen with a pale stripe down the

centre.

Length 4-53 ; breadth of the pronotum in the winged form 13-2, of that of the apterous form 14-1} millim.

Hab. Panama, Bugaba (Champion).

Found plentifully on the surface of the water of small streams in the forest-region

of the “tierra caliente,” the winged form predominating, three apterous specimens

only, all males, having been obtained. ‘This insect is extremely like R. elegans, Uhler,

from the Island of Grenada, it being of the same size and colour; but differs from that

insect in having the terminal genital segment in both sexes produced into a spiniform

process, and the two long inner teeth of the posterior femora less approximate. Both

species have a long, slender hook at the apex of the posterior tibize, a character over-

looked by Prof. Uhler.

9. Rhagovelia insularis, n. sp. (Tab. IX. figg. 3, winged ¢ ; 3a, apex of

abdomen, ¢ .)

Winged form. Moderately elongate ; the head brownish-black, flavous in front; the pronotum rufo-castaneous,

bordered broadly in front and narrowly behind with flavo-fulvous, and with a similarly-coloured, evanescent,

median line anteriorly ; the elytra blackish-brown ; the body beneath and the connexivum flavous, the

venter and the pleura greyish-white ; the antenne and legs black with a faint neous lustre, the antenne

at the base, the anterior femora beneath and at the base above, the hind femora beneath, the coxe, the

anterior trochanters, and the intermediate and hind trochanters in part, flavous; the body, legs, and

antenne very finely pubescent, the head, the sides of the body, the three basal joints of the antenne, and

the legs somewhat thickly clothed with long hairs, the legs and joints 1 and 2 of the antenne also with

long scattered sete. Head with a smooth impressed median line; antenne rather slender, joint 1 one-half

longer than 2, 2-4 decreasing in length, 4 pointed at the tip. Pronotum sparsely punctured, the posterior

portion triangular, obtuse at the apex. LElytra extending to a little beyond the apex of the abdomen.

Legs rather stout; the posterior tibiae armed with a long, slender hook at the apex in both sexes; the

intermediate tarsi with joint 2 shorter than 3.

3 2. Posterior femora moderately incrassate, armed with five or six acute, curved teeth of unequal length,

these extending from about the middle to near the apex, the first, second, and fourth the longest, the

inner two a little more distant than the others; posterior tibie finely and obsoletely denticulate on their

inner edge.

Apterous form. Fusiform ; the pronotum abbreviated and rounded behind, the mesonotum and the dorsal surface

of the abdomen reddish-brown, the sutures and the lateral margins of the segments grey.

Length 4-43; breadth of the pronotum of the winged form 14-12, of that of the apterous form 13 millim.

Hab. Panama, San Miguel in the Pearl Islands (Champion).

Thirteen specimens, ten of which are winged. Very like &. uncinata ; but differing

from that species in the simple terminal genital segment of the abdomen, the shorter

and slightly stouter legs, the reddish dorsum of the pronotum, and the armature of the

hind femora, the two inner teeth being more approximate than in that insect. The

less elongate form, shorter legs, and the reddish pronotum separate it from &. elegans.

The hind femora are similarly formed in both sexes. ‘The second and third joints of

the hind tarsi are very closely articulated.

140 HEMIPTERA-HETEROPTERA.

The insect was found on the surface of freshwater streams in the Isla del Rey, the

largest of the Pearl Islands.

TROCHOPUS.

Trochopus, Carpenter, Ent. Monthly Mag. xxxiv. p. 78, t. 3 (April 1898).

The type of this genus is 7. plumbeus (Uhler) (= marinus, Carp.), from the Antilles

and Florida, and the species from the Pearl Islands now added is an allied form. It

differs chiefly from Rhagovelia in having the tarsi 3-, 2-, 2-jointed, the very small basal

joint of the intermediate pair being obsolete, and the second and third joints of the

hind pair fused into one. The two species are constantly apterous, and have the

pronotum reduced to a short lobe, the larger portion of the disc of the thorax being

occupied by the mesonotum.

The beautiful structure of the intermediate tarsi has been figured by Mr. Carpenter

(loc. cit.). The males have a row of short teeth on the inner edge of the posterior

tibie, that of 7. salinus having, in addition, a long tooth on the anterior trochanters.

It is probable that, as in the pelagic Halobates, &c., wings would be of very little use

to these insects, the water upon which they live never drying up; whereas in the fresh-

water [thagoveliw, which have occasionally to migrate when the streams dry up, wings

are a necessity, at least in a certain number of individuals of each species.

Both insects live gregariously on the surface of salt-water in sheltered creeks

and inlets.

1. Trochopus salinus, n. sp. (Tab. IX. figg. 4, ¢, from beneath; 5, 2, from

above. )

Ovate (2 ), subfusiform ( ¢ ), black or brownish-black, mottled with grey, beneath entirely grey, the pronotum,

except at the sides, the connexival margins broadly, and the apex of the abdomen more or less, above and

beneath, ferruginous ; the antenne brownish-black, with the basal half or more of the first joint flavous

or ferruginous; the legs brownish-black, the anterior and hind femora in great part, and the intermediate

femora at the base, ferruginous or flavo-ferruginous; the coxe and trochanters flavous; the upper surface

thickly clothed with pale brownish pubescence, the head, pronotum, and pleura also with bristly hairs, the

under surface with greyish pubescence; the antenne and legs thickly pubescent, and also clothed (the

two outer joints of the antennz excepted) with long fine hairs and a few sete. Head with a smooth

impressed median line; antenne long and slender, joint 1 twice as long as 2, 2 and 4 subequal in length,

3 considerably longer, 4 fusiform, 2 and 3 separated by a distinct jointlet. Pronotum separated from the

mesonotum by a deep transverse suture, the mesonotum slightly sinuate behind. Connexivum raised and

broadly expanded. Legs long and rather stout, the intermediate pair very long, with the penultimate

tarsal joint much longer than the apical one.

6. Anterior trochanters armed with a long, acute, outwardly-directed tooth ; posterior femora slightly incras-

sate, armed with a row of minute teeth, and with a longer and rather prominent tooth at the middle.

@. Posterior femora feebly incrassate, unarmed, or, at most, with one or two minute teeth about the middle.

Length 31-34, breadth 12-14 millim.

Hab. Panama, San Miguel in the Pearl Islands (Champion).

Found in abundance in small creeks reached by the tide, in the mangrove swamps of

the Isla del Rey, or San Miguel, the largest of the Pearl Islands.

TROCHOPUS.—VELIA. 141

This species is allied to T. plumbeus (Uhler) (= marinus, Carp.), an insect living on

salt water in sheltered places on the shores of Grenada, St. Vincent, Jamaica, and the

Florida Keys; but differs from it in having stouter legs, with the hind femora more

incrassate, especially in the male, the penultimate joint of the intermediate tarsi

shorter, the apical joint of the hind tarsi and also that of the antenne more elongate,

the connexivum very much narrower, the body more ovate in shape, &c.

very finely pubescent, and also thickly clothed with long, fine, pallid hairs ; the pleura, a spot at the sides

of each of the ventral segments, a triangular mark on each side of the pronotum anteriorly, and a spot on

both the anterior and posterior sides of each of the femora towards the base, clothed with short silvery

pubescence. Head with a smooth, faintly impressed median line; the eyes large and coarsely faceted,

reaching the anterior margin of the pronotum; the antenne long and slender, joint 1 stouter, and fully

Of this species we possess a winged pair and one apterous female from Panama, and

two apterous males from Guatemala, these agreeing with Stal’s V. brachialis and with

the Grenada specimens named JV. stagnalis by Prof. Uhler. There is also a winged

male from Mexico in the Vienna Museum. They differ from one of Burmeister’s types

of V. stagnalis, an apterous female, communicated by the Berlin Museum, in having

a much longer second joint to the intermediate tarsi (joints 2 and 3 being equal in

length in V. stagnalis), and larger and more coarsely faceted eyes (the eyes in V. stagnalis

do not reach the front of the pronotum). ‘The apterous specimens are also less parallel

than the type of V. stagnalis before me, and have the pronotum less produced behind.

The posterior femora are not thickened in the male; the denticulation is so fine as to

be scarcely visible, except in immature examples. Stal’s type, a male example without

antenne, is now before me. The two apterous North-American specimens in the British

Museum were collected and presented by E. Doubleday.

144 HEMIPTERA-HETEROPTERA.

Unknown to me. Described from an apterous specimen, presumably a male. The

insect is 74 millim. long, black, with the usual silvery-pubescent markings; the legs

are brown, paler beneath and at the base of the anterior femora; the posterior femora

are armed with two spines on the inner side beyond the middle; the antenne* are

long and slender, with joints 1 and 2 subequal in length.

Subfam. GERRINA.

The subfamily Gerrine is usually divided into two groups t, characterized by the

relative length of the abdomen, the latter being very short in the pelagic Halobates

and its allies. This character, however, is so unsatisfactory that it cannot be used—

Brachymetra having the abdomen scarcely shorter than in some species of Gerris, and

Potamobates being closely related in other respects to Platygerris. In the last-mentioned

genera the genital segments of the males are asymmetrically formed, these segments

being furnished with angular or dentiform processes on one side of the body only.

Halobates occurs in the vicinity of the Atlantic and Pacific coasts of Central America,

and I have seen one species in plenty on the surface of the sea, in the Gulf of Nicoya,

Costa Rica; but as the marine forms are excluded from the scope of this work, nothing

more need be said about it.

best dropped #.

The species here referred to Gerris have the two joints of the anterior tarsi subequal

This is the largest of the Central-American species of the genus, and it is apparently

referable to G. remigis, Say, which is compared by its describer with G. paludum, Fabr.

Numerous winged and apterous specimens of both sexes have been examined. The

colour, as well as the sculpture, of the posterior portion of the pronotum is variable.

The anterior femora are very stout. The male has the venter sulcate down the middle,

with two large blackish spots on each segment, the sixth broadly and deeply emarginate

at the apex. The female has the venter obsoletely canaliculate, with a dark stripe

down the centre, divided by a pallid line. In the larger males the anterior femora are

greatly incrassate. The following is a very closely allied form.

Fourteen Mexican specimens, including winged and apterous specimens of both sexes,

are referred to this species. They are very closely allied to G. remigis; but differ from

it'in the form and coloration of the venter in the male, and in the more acute connexival

spines in both sexes. The posterior portion of the pronotum is constantly ochraceo-

ferruginous or rufescent. In the male the venter is shallowly grooved down the middle,

and, at most, slightly infuscate on each side of the median groove.

The original description was made from a badly mutilated female example. I have

seen a Mexican specimen, received from Mr. C. Baker of Auburn, Alabama, which I

believe has been determined by Prof. Uhler as G. robustus.

The present insect somewhat resembles G. rufoscutellatus, Latr.; but it is more robust

and less parallel, and has shorter connexival spines, &c.

the sixth ventral segment simply emarginate at the apex; two upwardly curved spines

or hooks, one on each side of the hidden penultimate genital dorsal segment, are visible

from beneath in this sex, as described by Mayr. In the winged form the pronotum is

very feebly constricted at the sides, the anterior lobe being completely fused with the

posterior lobe, without trace of suture.

POTAMOBATES, n. gen.

Head subtriangular, produced and declivous in front, angularly dilated on each side above the insertion of the

antenne; the eyes rather coarsely faceted, large, oblique, somewhat narrowly separated anteriorly, and

feebly emarginate posteriorly ; rostrum 4-jointed, short, reaching the front of the mesosternum ; antenne

about half the length of the body, joint 1 nearly as long as the others united, 4 longer than 3, 2 and 3

separated by a distinct jointlet. Thorax elongate-trapezoidal, gradually widening to the intermediate coxe ;

the pleura broad and laterally prominent, the propleura rounded externally and extending outwards to at

least as far as the eyes, the mesopleura still wider; the pronotum in the winged form covering the meso-

notum, rather narrow, gradually widening to the shoulders and rounded behind ; the mesothorax separated

from the metathorax by a deep sinuous suture, the metapleura rounded laterally in front and widening to

the laterally prominent hind cox. Abdomen rather short, with broad, raised connexivum, which is

slightly produced at the outer apical angle; two genital segments visible above and beneath in the male,

one in the female; genital segments in the male subcylindrical, the first as long as the two or three

preceding segments united, the second narrower, both asymmetrically formed; terminal genital dorsal

segment in the female subtriangular and as long as the preceding segment, the terminal genital ventral

segment triangular, membranous, and separate, in this sex. Anterior legs short, the coxe widely

separated; the femora stout, becoming incrassate towards the base; the tibiee curved at the apex, with

the inner apical angle sharp; the tarsi with the basal joint short, not half the length of the second.

Intermediate and hind legs very elongate; hind femora thinner and longer than the intermediate femora,

about one and three-fourths the length of the tibia and tarsus united; second joint of the hind tarsi much

shorter than the first. Body rarely winged, the mesonotum flattened and shining in the apterous forms.

This genus forms a connecting link between the freshwater Halobatine forms,

Platygerris &c., and the normal Gerrids. It differs from Platygerris in the larger

and more oblique eyes, which are somewhat narrowly separated in front, the much

longer abdomen, the elongate-trapezoidal mesothorax, with the pleura not distinctly

separated from the notum, the elongate first genital segment in the male, &c. As in

Platygerris and various species of Halobates, the genital segments are asymmetrically

formed in the male. From Gerris and its allies, the present genus differs in the shape

of the head, eyes, and mesothorax, as well as in the asymmetrical genital segments of

the male. The two species may be separated thus :—

Hab. Panama, Bugaba (Champion).

One winged female and numerous apterous specimens of both sexes have been

obtained of this species. The asymmetrical armature of the two genital segments of

the male is quite constant. The anterior femora sometimes have the base ‘only

testaceous. The mesothorax in the apterous form is about two and one-half times

the length of the prothorax; it is shaped somewhat as in Platygerris, but the meso-

pleura are narrowed forwards.

PLATYGERRIS.

Platygerris, Buchanan White, Ent. Monthly Mag. xx. p. 36 (1883).

The apterous Mexican insect referred to this genus has been described at great length

by Buchanan White. A second species, from Costa Rica, of which we possess a winged

example, is now added. ‘They live upon the surface of fresh water.

1. Platygerris depressus. (Tab. IX. figg. 23,3; 24, apex of the abdomen

from above, 2; 24 a, ditto, from behind.)

Platygerris depressa, Buch. White, loc. cit. pp. 36-89 (¢)’.

Hab. Mexico (Mus. Berol.!: 3), Teapa in Tabasco (7. H. Smith: 3 @ ).

Two pairs of this species have been received from Teapa. The females have the

apex of the last ventral segment subtriangularly produced in the middle and furnished

on each side with a rather long narrow lobe, these being conspicuous from above; the

first genital ventral segment is vertical and fissured to the base, the apex of the abdomen

appearing abruptly truncate. The insect is described as black, but the specimens before

me, including one of the types, have a bluish or eneous lustre above.

Buchanan White, in describing the form of the genital segments of the male, assumed

that they were distorted in drying; but this is not the case, the armature being asym-

metrical, as in various other species of the group: the first genital ventral segment * is

* The second segment of Buchanan White, his first genital segment being here regarded as the terminal

ventral.

PLATYGERRIS.—TREPOBATOPSIS, 157

somewhat twisted on the right side posteriorly, and there produced into a very long

spiniform process, and the second genital dorsal segment is armed on the same side at

the base beneath (the left side as seen from above) with a very long,*acute, slightly

curved spine. The three males seen agree precisely in this respect.

an oval spot between the eyes and the pronotum with a median line on the anterior lobe fulvous; the

anterior femora at the base beneath, the intermediate and hind cox beneath, a spot on the underside of

the ante-coxal pieces of the meso- and metapleura, the prosternum, and venter ochraceous; the elytra and

wings smoky-brown; the under surface and pleura thickly clothed with short silvery pubescence, the

pronotum and legs with greyish pubescence, the anterior femora with a few long hairs on the lower edge ;

the head, pronotum, and mesonotum shining, the pleura and under surface opaque. Antenne with joint 1

very elongate, about three times as long as 2 (3 and 4 broken off). Pronotum gradually widening

posteriorly, rounded behind, leaving the metanotum exposed, sharply separated laterally from the meso-

pleura, the hind angles tumid, the anterior lobe broadly depressed in the middle. Mesopleura broad and

parallel. Elytra as long as the entire body, and about one-third longer than the wings. Anterior femora

femora longer than the intermediate femora, the intermediate tibie not half the length of the femora of

the same pair of legs. Terminal ventral segment with a broad, transverse, vertical, upwardly directed

plate at the apex, covering the genital segments.

One specimen. Larger and more parallel than P. depressus, with a more elongate

basal joint to the antenne, and very differently formed terminal ventral segment.

TREPOBATOPSIS, n. gen.

at the base, longer than the others united, 2 and 3(¢) furnished with dentiform processes at the apex

beneath. Pronotum very short, much narrower than the head (with the eyes), subtruncate in front and

behind, rounded at the sides, and depressed in the middle; the propleura vertical, narrowing downwards,

and not visible from above. Mesonotum trapezoidal, sinuate at the sides, and trisinuate behind, not

distinctly separated laterally from the pleura; the latter very broad, rounded at the sides in front,

extending forwards as far as the eyes and backwards to beneath the metapleura. Metanotum with a

deep oblique groove on each side; metapleura broad, extending backwards to as far as the apex of the’

second dorsal abdominal segment. Abdomen very short, with moderately broad, flattened connexivum,

the six segments united shorter than the mesonotum; first genital segment ( ¢) very broad, parallel, as

long as the three preceding segments united, covering two small terminal segments, which are not visible

from above. Anterior coxe narrowly separated, the ante-coxal pieces received in the cavity beneath the

eyes; anterior femora ( 3 ) slender, about one-third longer than the tibia, armed with a stout tooth on the

lower edge; anterior tibie armed with a strong curved tooth at the inner apical angle; anterior tarsi

length of the tibiz of the same pair of legs. Mesosternum separated from the mesopleura by a welle

defined groove, which extends forwards to beyond the middle. Body short, broad, depressed, apterous.

158 HEMIPTERA-HETEROPTERA.

The remarkable insect from which the above characters are taken is perhaps nearest

allied to Trepobates, Uhler (= Stephania, Buch. White). The greatly developed meso-

notum, with te broad pleura extending forwards as far as the eyes, gives it a peculiar

facies. The armature of the second and third joints of the antenne, and also that of

the anterior femora, is probably a male-character. The hind femora, as in Trepobates

and Metrobates, are very much longer than the intermediate femora. (In the unique

example seen the intermediate tibie and tarsi are broken off.) In Bianchi’s arrange-

ment of the Halobatini* it would come near Metrobates, Uhlerf, this genus having

a similarly elongate basal joint to the antenne.

1. Trepobatopsis denticornis, n.sp. (Tab. IX. figg. 26, ¢; 26a, antenna.)

3. Black, opaque ; a broad sinuous stripe on the mesopleura, a stripe down the middle of the mesonotum,

two spots on the metanctum, as well as the sides, the middle and sides of the dorsum of the abdomen,

and the metapleura, grey: the head with two oblique ferruginous spots at the base; the pronotum with

a rounded ochraceous spot in the centre; the under surface bluish-grey, the apex of the abdomen and a

spot on the ante-coxal pieces of the mesopleura ferruginous or ochraceous; the first antennal joint at the

base beneath, and the second joint to near the tip, ochraceous; above and beneath, the legs, and antenne

clothed with short pubescence, the pubescence on the under surface whitish, the basal joint of the

antenne with a few long projecting hairs beneath. Antenne: not very slender, joint 1 about three and

one-half times as long as 2, 2 and 4 subequal in length, 3 shorter than 2, 4 fusiform; joint 2 armed with

two, and 3 with four, blunt, downwardly projecting teeth at the apex beneath. Anterior femora armed

HENICOCEPHALUS. 159

This extraordinary genus contains fourteen described species, half of which are

American *. Six are known to me from Central America, five of them being here

treated as new. Some authors (including Westwood) describe the intermediate and

hind tarsi as 3-jointed ; but there are in reality only two joints—a short basal and a

long apical one. I am unable to distinguish the sexes.

The anterior tarsi in some species have two long claws at the apex, and in others

(including H. jflavicollis, Westw.) one only. The tarsi themselves are retractile

inwards, and the insect is thus enabled to grasp its prey between the long claw or

claws and the sharp tibial spurs. The anterior tibie are more or less grooved along

their inner face towards the apex.

The six Central-American species may be tabulated thus :—

a. Discal cell of the elytra closed ; posterior lobe of the head transverse,

dull, pilose. [Hymernocoris, Uhl. |

a’, Anterior tarsi with two long claws.

a", Antenne with joints 1 and 2 much stouter than the others, the

latter very slender; pronotum deeply emarginate behind ; pos-

terior lobe of the head strongly transverse ; ocelli very small ;

pilosity of the head and pronotum short; legs unicolorous . . concolor, n. sp.

6", Antenne with the two basal joints a little stouter than the others ;

pronotum less deeply emarginate behind; posterior lobe of the

head moderately transverse; ocelli prominent; pilosity of the

head and pronctum long; legs annulate . . . .. . . annulipes, n. sp.

b!. Anterior tarsi with a single long claw; posterior lobe of the head

strongly transverse; pronotum deeply and angularly emarginate

behind.

c', Antenne elongate, the three outer joints slender; ocelli very small ;

pilosity of the head and pronotum close; intermediate lobe of

the pronotum broad and as long as the posterior lobe . . . . pilosus, n. sp.

d", Antenne much shorter, the two outer joints slender; ocelli

prominent ; pilosity of the head and pronotum sparse ; inter-

mediate lobe of the pronotum short, much narrower than the

posterior lobe . . . . emarginatus, 0. sp.

b. Discal cell of the elytra open; posterior lobe of the head subglobose,

smooth, shining; anterior tarsi with two long claws. [Hymeno-

pectgs, Uhl. |

c’. Rather robust, anterior legs very stout, intermediate lobe of the

pronotum longer than the posterior lobe . . . . - . . a@ngustatus, 0. sp.

d', Slender, anterior legs moderately stout, intermediate lobe of the

pronotum not longer than the posterior lobe . . . . . . . . culicis, Uhler.

* Two others, from Venezuela, have been noticed by Dr. Bergroth (Rev. d’Ent. viii. p. 319), but he has

not yet published descriptions of them.

Two examples. Narrower and less robust than H. concolor, the two basal joints of

the antenne relatively more slender, the posterior lobe of the head less transverse, the

ocelli more prominent, the pronotum not so deeply emarginate behind, the knees

pale, the hairs on the head and pronotum longer. The anterior tarsal claws are so

closely placed that at first sight one only is visible.

162 HEMIPTERA-HETEROPTERA.

Hab. Guatemata, Volcan de Fuego 6400 feet (Salvin), Quezaltenango 7800 feet

(Champion). :

_ Two examples, both in a bad state of preservation, the one from Quezaltenango

being without head. This insect is very like H. culicis, but apparently belongs to a

different species: it is more robust, the legs are stouter, the anterior femora and tibie

being much more thickened, the median lobe of the pronotum is relatively longer and

broader, and the antenne are a little less slender. The Quezaltenango specimen has

the anterior legs enormously developed, with the tarsal claws very elongate. The

elytra and wings are creased and mutilated in both examples. |

The three Mexican specimens referred to this species, one of which has been

| received from Mr. C. F. Baker under the above name, agree very well with

Mr. Ashmead’s description. The insect is very like H. angustatus. It has the elytra

subhyaline and iridescent, with the discal cell open, the scutellum longitudinally

carinate at the apex, the joints 2-4 of the antenne long and very slender, the

posterior lobe of the pronotum * shallowly emarginate behind, the posterior lobe of

the head smooth and subglobose, the ocelli prominent, and the lower anterior tarsal

claw shorter than the upper one. JH. culicis appears to be known from various other

localities in the United States f. |

Fam. REDUVIIDZE.

Subfam. HMESINA.

The species of this subfamily of Reduviide are easily recognizable by their raptorial

front legs, with very elongate cox; the head is without ocelli. In some of the

genera the anterior tarsi are long, rigid, and claw-like, with the joints fused into one.

Ghilianella and Ploiaria (Cerascopus) are completely apterous. All are very slender,

elongate insects. _ |

The systematic arrangement adopted here is a little different from that of Stal or

Dohrn, more importance being attached to the form of the thorax, as may be noticed

from the characters used in the subjoined key of the genera.

A widely distributed genus including a few Palearctic species, and also represented

Ploiariodes was based upon one of those forms with the pronotum tuberculate in the

centre at the base, and the single Central-American representative belongs to that

group.

1. Ploiariodes armata, n. sp. (Tab. X. figg. 9, 9a; 9 6, anterior leg.)

Very slender, sparsely pubescent, opaque; ochraceous, mottled with fuscous, the body beneath and the

abdomen, the connexivum excepted, blackish or fuscous; the pronotum with two ochraceous or whitish

vittee on the disc of the posterior lobe, the sinuous lateral carinze white, the basal elevation fuscous or

blackish ; the elytra reticulated with white, the interspaces more or less fuscous, the apical third with

some more or less distinct reddish-brown markings ; the legs, rostrum, and antennw whitish or whitish-

ochraceous, closely speckled or annulated with nigro-fuscous, the anterior legs sometimes more broadly

annulated than the others. Head with a deep transverse groove between the eyes, the latter large and

prominent ; antenne very elongate, with joints 1 and 2 subequal in length, 2 nearly twice as long as

3 and 4 united, 4 about one-third the length of 8. Pronotum with a short, abrupt, subangular, cariniform

elevation on the middle of the disc just before the posterior margin. Scutellum, post-scutellum, and base

of the abdomen each with a long semi-erect spine. Anterior femora with a row of short fine teeth along

their lower edge.

Length (to apex of the elytra) 5-6 millim.

Hab. Guatemaa, Capetillo (Champion); Panama, Bugaba (Champion).

Three specimens, one of which has lost its head, this example having all the legs

broadly annulated with fuscous. P. armata is allied to the Palearctic P. berensprungi,

Dohrn, and P. brevispina, Puton, but it has much larger eyes, &c.

LUTEVOPSIS, n. gen.

Head about as long asthe anterior lobe of the pronotum, parallel in front, convex and obliquely narrowing

behind, without frontal spine, the eyes prominent ; rostrum with the two basal joints subequal in length ;

antenne with joints 1 and 2 exceedingly elongate. Pronotum elongate, divided into two parts of nearly

equal length, the anterior lobe cylindrical, somewhat arched, and gradually widening forwards, the

posterior lobe convex, broader, and covering the mesothorax. Meso- and metathorax short, subequal in

length, together not longer than the pronotum. Scutellum unarmed. Elytra extending to near the apex

of the abdomen. Abdomen elongate, narrow at the base, subovate. Anterior coxe elongate, about as -

long as the tibia. Anterior trochanters unarmed. Anterior femora long and subcylindrical, slightly

longer than the tibia and tarsus united, armed with a series of spines, which extend from the base to

beyond the middle. Anterior tibie very finely denticulate within. Anterior tarsi short, a little longer

than the hind tarsi, slender, with three distinct joints and two claws. Intermediate and hind legs slender

and very elongate, the hind femora extending to beyond the abdomen. Body elongate, slender, winged.

The two species referred to this genus differ greatly inter se in the form of the head

and anterior legs, but the general structure of the thorax, anterior tarsi, &c. is similar,

and they can be included under one generic name for the present. Lutevopsis some-

what approaches Luteva, Dohrn; but in that genus the anterior tarsi are long,

compressed, and claw-like, and not articulate, the pronotum is reduced to the portion

corresponding to the anterior lobe of that of Lutevopsis, &c. The differently formed

pronotum and the unarmed scutellum separate it from Malacopus, Stal. The series of

spines on the anterior femora start from close to the base, instead of from near the

middle, as in Gardena, Emesa, &c., and the first one is not longer than the others.

The elytral neuration is very like that of Emesa (longipes, De G.).

Anterior legs very elongate, the femora with prominent spines; head consi-

derably prolonged posteriorly, not swollen in the middle before the eyes ;

pronotum very elongate, the two lobes separated on the disc by a deep

transverse groove, the anterior lobe dull; elytra without distinct markings. longimanus, un. sp.

Anterior legs much shorter, the femora with very short fine spines; head much

less prolonged posteriorly, gibbous in the middle before the eyes; pro-

notum shorter, the two lobes not separated by a transverse groove, the

anterior lobe smooth and shining; elytra with definite markings . . . ornata, n. sp.

1. Lutevopsis longimanus, n. sp. (Tab. X. figg. 10, 10a, ¢.)

Elongate, slender, nigro-piceous, the head, the anterior lobe of the pronotum in great part, the basal joint of

the antenne, the rostrum, and legs ferruginous, the connexival sutures indicated by a small ochraceous

spot; the elytra fusco-hyaline, with darker nervures; finely pubescent, the anterior femora and tibie

ciliate within, the anterior tibia with some golden hair on the outer edge towards the base; the basal

joint of the antenne clothed all round with long, fine, projecting hairs; the head slightly shining, the

pronotum opaque. Head very much longer than broad, considerably prolonged and narrowing behind

the eyes, the eyes rather small. Pronotum very elongate, the two lobes divided on the disc by a deep

transverse suture; the anterior lobe scabrous and considerably widened forwards, the posterior lobe

transversely rugulose. Elytra reaching to the apex of the sixth abdominal segment. Abdomen with the

sixth dorsal segment produced into a broad thin plate, which is curved upwards and covers the genital

segments, its apex being narrowly truncate; terminal genital segment inflated beneath. Anterior legs

very elongate, the femora with about five rather long spines and some shorter spines between them.

on each side in front and the scutellum also with a fuscous line on each side; the elytra with three

equidistant groups of three or four dilute fuscous, oblong or rounded spots along the middle of their

apical half; the wings iridescent; the pronotum, the basal joint of the antennew, and the femora

sparsely clothed with very long fine erect hairs, the other parts of the body and the antcrior tibia finely

pubescent. Head with the eyes about as wide as the base of the pronotum, and as broad as long, smooth,

convexly gibbous before the transverse groove, narrowed and globose behind, the eyes moderately large ;

antenne very slender and exceedingly elongate, joints 1 and 2 subequal in length, 2 more than twice as

long as 3 and 4 united, 4 twice as long as 3. Pronotum with the anterior lobe smooth and cylindrical,

widening forwards, as long as the head, deeply sulcate along the middle at the base; the posterior lobe

trapezoidal, wider and a little longer than the anterior lobe, densely punctulate, slightly depressed along

the middle. Elytra reaching to the apex of the sixth abdominal segment. Abdomen widening from the

base to about the middle, curved upwards at the apex, the genital segments exposed. Anterior legs

comparatively short, the femora very minute denticulate and with four widely separated, very short, fine

spines, extending from near the base to beyond the middle.

Length 74 millim. (<¢.)

Hab. Panama, Bugaba (Champion).

One example. Easily distinguishable from all the allied forms by its pallid colour

and the three clusters of dilute fuscous spots on the elytra. The four spines on the

anterior femora are very short and fine, and not easily seen.

GARDENA.

Gardena, Dohrn, Linn. Ent. xiv. p. 214 (1860), and xv. p.64; Stal, Enum. Hemipt. iv. pp. 93, 96.

The genus Gardena has not hitherto been recorded from America, though the

commonest of the Central-American Emesids agrees well with Stal’s definition of it

(Enum. Hemipt. iv. p. 93). This insect is very like Emesa longipes (De Geer), but

differs from it in several points of structure: the anterior tarsi are very short and

distinctly 3-jointed; the series of long spines on the anterior femora, which extend

from a little before the middle to near the apex, are subequal in length, the femora

themselves being about twice the length of the tibie. The anterior tarsi are

bi-unguiculate *.

1. Gardena americana, n. sp. (Tab. X. figg. 12, ¢; 12a, anterior leg.)

Winged form. Very elongate, slender, reddish-brown or ferrugineo-testaceous, the meso- and metathorax, the

thickened basal portion of the pronotum, and the base of the cox, piceous or black, the abdomen varying

in colour from ferruginous to fuscous, the antenne fuscous, the anterior knees usually piceous; the

intermediate and posterior femora with a blackish annulus before the tip, the tip rather broadly white;

the intermediate and posterior tibiee narrowly biannulate with white at the base, the outer white ring

sometimes followed by a dark one; the elytra fusco-hyaline, narrowly ochraceous at the base, the wings

hyaline ; the body almost glabrous, the anterior legs pubescent, the head and thorax smooth and shining.

Head without frontal spine, the eyes prominent; antenne with the two basal joints exceedingly elongate,

subequal in length. Pronotum elongate, with the portion covering the mesothorax about one-third of the

whole length, convex, and considerably dilated, the median portion very narrow and cylindrical, the

anterior portion gradually widened forwards. Meso- and metathorax short, subequal in length, together

shorter than the narrow portion of the pronotum. Elytra and wings extending to beyond the middle

of the abdomen, about reaching the apex of the third segment. Abdomen very elongate. Anterior

femora with a row of seven, rather long, fine spines of equal length, extending from a little before

the middle to near the apex, and with some short spines between them. Anterior tibiee one-half the

length of the femora, minutely denticulate and closely ciliate along their inner edge. Anterior tarsi very

short, slender, with three distinctly defined joints, and two narrowly separated claws of equal length.

* The anterior tarsal claws are described as simple by Dohrn, and bi-unguiculate by Stal.

168 HEMIPTERA-HETEROPTERA.

Apterous form. Pronotum not extending backwards over the mesothorax, and longer than the meso- and

metathorax united.

6. Antennsg with joint 1 and the basal half of 2 clothed all round with very fine, rather long , projecting

hairs. Abdomen narrow, with two exposed genital segments; the terminal genital segment long, very

convex beneath, acutely produced and curved upwards on each side above.

I follow Stal in restricting this genus to £. longipes and its allies, these species

having the anterior tarsi long, compressed, and claw-like, non-articulate, and biungui-

culate. They are winged, and have the very long neck-like portion of the thorax

formed entirely by the pronotum, this latter being extended backwards over the

mesothorax in fully-developed specimens. The armature of the anterior femora is

similar to that of Ghilianella. The head is without frontal spine.

_ EMESA.—GHILIANELLA. 169

This widely-distributed species is not uncommon in Central America, occurring on

both the Atlantic and Pacific slopes. The basal third of the abdomen is sometimes

bright red, the head often has two fulvous vittee behind the transverse groove, and the

annulation of the legs is not always distinct, the intermediate and hind pairs, however,

have the knees constantly whitish. The nymph is so different from the fully developed

form that a description of it is given below, chiefly taken from a broken example from

Atoyac (where the winged form was also obtained), supplemented by a less mature

North-American specimen in the British Museum ; this latter has the intermediate and

hind knees white, as in the developed form.

Nymph. Eixceedingly slender and elongate, almost glabrous, smooth, somewhat shining; the head ochraceous,

with two narrowly separated vitte on the anterior portion and the sides before and behind the eyes

fuscous ; the pro-, meso-, and metanotum and the abdomen ochraceous, with the sides broadly fuscous,

the mesonotum with two fuscous vitte ; the wing-pads ochraceous externally, fuscous within ; the anterior

legs ochraceous beneath, fuscous above, the tarsi and the outer half of the tibie broadly annulated with

pale ochraceous; the intermediate and hind legs brownish, with the knees blackish, the femora towards

the tip and the tibia near the base biannulated with pale ochraceous ; the antenne brownish, with the tip

of the basal joint ochraceous. Head without frontal spine, the eyes prominent. Prothorax exceedingly

elongate, as long as the meso- and metathorax united, the metathorax longer than the mesothorax ;

the pronotum narrow and cylindrical behind, widening forwards, and swollen at the base, obsoletely

canaliculate; the pleural margins very minutely denticnlate. Wing-pads extending to a little beyond

the base of the metanotum. Abdomen very elongate, linear.

Length 30 millim.

GHILIANELLA.

Ghilianella, Spinola, Mem. Soc. Ital. Sci. xxv. p. 142 (1852) ; Dohrn, Linn. Ent. xiv. pp. 218, 236

(part.) ; Stal, Enum. Hemipt. ii. pp. 125, 126.

Stal distinguishes this genus from Emesa by the uni-unguiculate anterior tarsal

claws, the tarsi themselves being long, compressed, and claw-like, and non-articulate

in both genera; he also uses the granulation of the head and thorax asa distinguishing

character, but this cannot be depended upon. It may be noted that the mesothorax

in Ghilianella is prolonged into a long neck in front and abruptly separated from the

prothorax, whereas in Hmesa the long neck is formed entirely by a backward prolonga-

tion of the pronotum. ‘The species of Ghilianella, moreover, are constantly apterous,

without even the rudiments of wing-pads; some of them have the abdomen abruptly

inflated at or before the apex, the form of dilatation being very dissimilar in the two

sexes, a fact not even suspected by Dohrn. The anterior tibie are comparatively

short. ‘lhe anterior femora are armed before the middle with one very long spine,

between which and the apex is a series of much shorter spines, alternating with still

shorter spines or teeth. ‘The head has a well-developed frontal spine. One of the

South-American species of Ghilianella (G. filiventris, Spin.) was described by Fabricius

as the larva of an Emesa (EL. precatoria, Fabr.).

The Central-American species may be separated thus :—

@. Abdomen gradually inflated from a little below the base of the third segment to about the apex of the:

fifth and then narrowed to the apex, the inflated portion oval in shape; the fifth dorsal segment angularly

dilated at the apical angles, and with a prominent tubercle in the centre a little before the apex; the sixth

dorsal segment widening forwards and truncate behind; the two genital segments abruptly declivous.

Length 20-22 millim.

Hab. Panama, Bugaba (Champion).

Found in numbers at Bugaba, males preponderating. Very like G. cgnorata, Dohrn,

but differing from it structurally in both sexes: the males have a more slender

abdomen, the apex of which is still more curved upwards, and the sixth dorsal segment

is much less acuminate (not covering the tip of the inflated terminal genital ventral

segment) and not carinate; the females have the inflated apical portion of the abdomen

oval in shape (instead of piriform), the fifth dorsal segment with a conspicuous tubercle

in the middle behind.

8. Ghilianella granulata, n. sp. (Tab. X. fig. 19, head, thorax, and

anterior leg.)

Slender, opaque, almost glabrous, ochraceous, the head and thorax indeterminately fuscous at the sides, the

anterior legs and the intermediate and hind femora faintly annulated with fuscous, the intermediate and -

hind tarsi fuscous; the head and thorax sparsely and conspicuously granulate. Head with a porrect,.

acute frontal spine, the posterior half gradually narrowed behind and very finely canaliculate down the.

middle, the groove continued down the anterior part of the pronotum, the eyes small and not prominent ;

antenne with joint 2 much shorter than 1. Pro- and metathorax subequal in length, the mesothorax

much more elongate ; the mesothorax considerably, the metathorax slightly, widened behind. Abdomen

with segments 1-4 filiform (the rest broken off).

Length (to apex of fourth abdominal segment 19) ? about 25 millim.

Hab. Brivish Honpuras, R. Hondo (Blancaneaux).

One example. This species being abundantly distinct from the other Central-:

American forms, I have ventured to name it, the mutilated condition of the abdomen

notwithstanding. The small, non-prominent eyes, the finely canaliculate basal portion

of the head, the conspicuous granulation of the head and thorax, the almost glabrous

body, and the pallid coloration separate it at once from G. tgnorata and G. bulbifera,

to which it is evidently allied. The head also is less narrowed behind than in these

species. In the British Museum there are specimens of a very similar form, with a

linear abdomen, from Jamaica and Santarem ; but they are less slender than the present

species and have more prominent eyes.

4, Ghilianella gibbiventris, n. sp. (Tab. X. fig. 20, .)

Comparatively robust, nigro-piceous or piceous, the legs annulated with ochraceous (the middle and hind pairs

in the female example ochraceous and faintly annulated with fuscous); finely pubescent, the head and

thorax obsoletely granulate. Head with a short, obtuse, porrect frontal spine, the eyes very prominent;

antenne with joint 2 very little shorter than]. Pro- and mesothorax subequal in length, the metathorax

much shorter, the mesc- and metathorax much widened posteriorly.

¢. Abdomen with the third segment widening from the base, the fourth segment arcuately inflated at the

sides and gibbous above, and the fifth widening forwards ; the sixth dorsal segment long and moderately

acuminate, strongly curved upwards posteriorly; the long terminal genital segment greatly inflated

beneath and partly visible from above.

@. Abdomen (apparently) widened from the base to the apex of the fifth segment, the sixth segment

subquadrate, the fifth with a conspicuous tubercle in the centre behind and the apical angles prominent ;

the genital segments abruptly declivous.

Length, ¢ 17, 2 about 23 millim.

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

One male and one female, probably belonging to the same species, the structure of

the head and thorax being quite similar in both of them*. The female, which has the

intermediate and hind legs much paler and the abdomen very much crushed, closely

resembles the same sex of G. angulata, recorded by Prof. Uhler from Panama; but

it has a short, obtuse, porrect frontal spine (instead of an acute curved one), a longer

mesothorax, &c.

I have not seen a specimen of this species from within our limits, and it is probable

to G. gibbiventris. ‘The larva of G. angulata has the head and thorax strongly

granulated.

Three species were referred to this genus by Dohrn, two of which were from Tropical

* Since these pages have been in type, I have seen a male of a closely allied species from Panama (belonging

to the Vienna Museum); it is very like G@. gibbiventris, but has a curved frontal spine and the head and

thorax conspicuously granulate.

LUTEVA.—PLOIARIOPSIS.. 173

America; one of these has been recorded by Stal from Mexico. In Luteva the anterior

tarsi are long and claw-like and not articulated, the anterior femora are armed from

the base with a row of closely placed slender spines, the anterior trochanters are armed

with one or two slender spines or sete, the pronotum is completely separated from the

mesonotum, the latter covering the mesothorax and extending forwards, and the elytra

reach the apex of the abdomen.

PLOIARIOPSIS, n. ven.

Head short, broad, subcylindrical in front, transversely convex behind, without frontal spine, the eyes large

and prominent ; rostrum 3-jointed, the two basal joints short ; antenne exceedingly slender, longer than

the body, the two basal joints very elongate. Prothorax short, subquadrate or narrowing behind, the

basal margin raised and dilated, forming a collar for the reception of the mesothorax. Mesothorax

extending forwards, twice as long as the metathorax, covered by the mesonotum, which is subconical and

longer than the pronotum. Scutellum without spine. LElytra extending to far beyond the abdomen, the

spaces between the main nervures closely reticulate. Abdomen narrow. Anterior coxe elongate, longer

than the tibie. Anterior trochanters armed with one or two long spines. Anterior femora as long as

the tibia and tarsus united, slightly curved at the base, armed on the lower side with two rows of long

spines, which extend from the base to near the apex, the spines on one or both edges arising from a series

of conical teeth. Anterior tibize comparatively short. Anterior tarsi a little shorter than the tibix, slender,

formed by three connate joints, and with a single claw. Intermediate and hind legs very elongate, the

hind femora extending to far beyond the apex of the elytra. Body elongate, very slender, winged.

Two small species are referred to this genus. These insects have the facies of

Ploiariodes, but with the general structure more nearly agreeing with that of Luteva,

from which they differ in the closely reticulated elytra and the peculiar armature of

the anterior femora. The pronotum is short, the mesothorax being entirely covered

by the mesonotum. The anterior tibiz in repose are received between the two rows

of long spines which extend along the lower edges of the femora, these spines arising

(on one or both edges) from prominent conical teeth. The antenne have their two

basal joints clothed with very long projecting hairs.

The two species may be differentiated thus :—

Head distinctly bituberculate between the eyes, with a short erect spine on the

basal declivity, the eyes very large; mesonotum deeply sulcate; anterior

femoral spines much shorter than the tarsi; intermediate and hind femora

conspicuously annulate towards the apex. . . . . . . . « «+ «) «megalops, n. sp.

Very sparsely pubescent, opaque ; the head and the pro- and mesonotum ochraceous, slightly mottled with

fuscous, the mesonotum with two fuscous lines on the middle of the disc; the elytra ochraceous,

reticulated with fuscous, and with a narrow oblique fuscous fascia near the apex ; the abdomen and under

surface nigro-piceous ; the antenne ochraceous, with the first and second joints fuscous at the apex; the

rostrum and anterior legs ochraceous, annulated with fuscous; the intermediate and hind legs ochraceous,

the femora with two whitish and two fuscous rings towards the apex, the tibie with two whitish rings

at the base; the coxee and trochanters fuscous. Head with the eyes wider than the base of the mesonotum,

with two prominent tubercles before the transverse inter-ocular groove and one behind it, and a short

erect spine in the centre of the basal declivity, the eyes very large; antenne with joints 1 and 2

exceedingly elongate, 2 slightly shorter than 1, each fringed all round with long, fine, projecting hairs,

8 and 4 short and subequalin length. Pronotum oblong-subquadrate, the basal margin moderately raised.

Mesonotum longer than the pronotum, subconical, distinctly margined at the sides, the disc deeply sulcate

down the middle and also finely canaliculate, the basal margin quadrituberculate. Scutellum with a

small pallid tubercle. Anterior femora with a row of five long spines on the outer edge beneath, arising

from conical teeth, and some short spines between them, and also with a row of short spines along the

inner edge, amongst which are about four longer ones intermixed.

Length (to apex of the elytra) 5 millim. (?¢.)

One example, in perfectly preserved condition. ‘The anterior femora are armed with

moderately long spines, these alternating, on the outer edge, with two short spines.

2. Ploiariopsis predator, n. sp. (Tab. X. figg. 22, 22 a.)

Very sparsely pubescent, opaque, nigro-piceous, the head and the disc of the pro- and mesonotum ochraceous ;

the elytra pale ochraceous, reticulated with fuscous ; the antennz brownish-ochraceous, with the first

joint whitish at the base ; the legs brownish-ochraceous, all the femora speckled with fuscous to the base,

the intermediate and hind pairs blackish at the apex. Head with the cycs as wide as the hase of the

mesonotum, grooved down the middle before the transverse groove and with an interrupted median carina

behind it, the eyes moderately large; antenne with joints 1 and 2 each fringed all round with long, fine,

projecting hairs (8 and 4 injured). Pronotum narrowed behind, the basal margin greatly raised and

forming a very prominent collar. Mesonotum much longer than the pronotum, subconical, shallowly

sulcate down the middle and obsoletely margined at the sides. Scutellum with a pallid tubercle.

Anterior femora with two rows of five or six very long spines, alternating with shorter spines, the longer

ones arising from conical teeth, which are longer on the outer than on the inner edge.

Length (to apex of the elytra) 53 millim. (? d.)

Hab. Guatemata, Capetillo (Champion).

One example. In this species the long spines on the anterior femora are, with the

conical tubercles from which they arise, nearly as long as the tarsi, and between them

there is an alternating series of single shorter spines.

One male specimen, about 6 millim. long, not unlike the Palearctic P. domestica,

Scop., but with a less dilated abdomen and longer spines on the anterior femora.

Subfam. BACTRODINA.

This subfamily of Reduviide includes a single genus, peculiar to the warmer parts of

America, and ranging from Central Mexico to the Argentine Republic. It differs from

the Emesine in having the anterior coxe less elongate and the lower portion of the

prothorax produced in front, as well as in the presence of ocelli.

BACTRODES.

Bactrodes, Stal, Rio Jan. Hemipt. p. 80 (1858) ; Enum. Hemipt. ii. p. 124.

Of the four described species of Bactrodes, two occur within our limits. In both of

them the anterior trochanters are armed with a sharp spine, and the anterior femora

are furnished with six or seven spines along their lower edge. The anterior tarsi have

two claws, the intermediate and hind tarsi one only.

Head and posterior lobe of the pronotum not spinose, the anterior lobe of the

latter feebly spinose at the sides towards the apex; scutellum with a short

spine; anterior femora biannulate and almost smooth above; abdomen not

Eighteen specimens have been seen of this insect (including the type), the four from

Subfam. SAICINAA.

This subfamily of Reduviide agrees with the Emesine in the absence of ocelli, but

differs from it in the much less elongate anterior coxe. ‘The three known Tropical-

American genera are all represented within our limits.

SAICA.

nota; Enum. Hemipt. i. p. 124, and iv. p. 91.

This genus includes three known Tropical-American species *, all of which occur

within our limits, whence two others are now added. Saica is easily recognizable by

the curved and unarmed anterior tibie, the long pronotal and scutellar spines, the long

intermediate and hind legs, and the setose (not spinose) anterior femora. These latter

have a row of sete along their lower face—in some species regularly arranged, and in

others broken up into clusters or fascicles,—and a second row of closely placed sete

along their anterior edge. From the lower sete, as well as from those on the

trochanters, a viscid substance is extruded by the insect (the sete being more or

less stuck together in all the specimens examined), no doubt to assist it in capturing

its prey.

Hab. Mexico!?; Guaremata, Cubilguitz in Vera Paz (Champion).

Of this species we possess a single female example, the type, which I have seen,

being of the same sex; the latter was probably obtained in Vera Cruz. S. fuscipes is

of a brilliant vermilion-red colour, with the tibize and femora, the base of the latter

excepted, the antenne, and elytra, the costal margin excepted, fuscous or nigro-fuscous,

and the tarsi fusco-testaceous. The pronotal spines are very long and acute. The legs

are relatively very elongate. The anterior femora are furnished on the lower side with

a row of closely placed sete,.in addition to the long fine hairs, and there are two

clusters of sete on the anterior trochanters beneath.

This insect is very like S. fuscipes, but differs from it in having the femora entirely

fuscous or nigro-fuscous, and the elytra ochraceous or brownish-ochraceous, the costal

margin included. The pronotal and scutellar spines are long, and they are usually

nigro-fuscous or tipped with that colour. The anterior femora are furnished beneath

with a row of closely placed sete, in addition to the long fine hairs. The anterior

trochanters have two clusters of sete beneath. St. Vincent and Grenada specimens

differ from those from the mainland in having much shorter pronotal and scutellar

spines.

3. Saica rubripes, n. sp. (Tab. XI. figg. 3, ¢ ; 3a, anterior leg.)

Elongate, moderately slender; dilute vermilion-red (fading to sanguineo-testaceous in dried specimens), the

coxe, femora, tibie, and antenne rufous or fusco-rufous, the tarsi fusco-testaceous, the pronotal and

scutellar spines flavescent, sometimes fuscous at the extreme tip, the elytra fusco-ochraceous; the legs,

body, and antennz thickly clothed with long fine hairs, the anterior femora also furnished beneath with

an irregular row of fascicularly arranged sete; the anterior trochanters with two clusters of sete beneath.

Eyes moderately large. Pronotal and scutellar spines moderately long and acute. Post-scutellum tuber-

culate in front and with a short acute spine behind. Intermediate and hind legs very elongate. Prosternal

spines acute and visible from above.

Length 14-15, breadth 21,-23 millim. (¢ 2.)

Not uncommon in Guatemala and Panama, occurring on both the Atlantic and

Pacific slopes. This species is very like S. recurvata (Fabr.), but it is smaller and less

elongate, and the pronotal spines are longer and usually whitish. In light-coloured

specimens the tibie, except at the base, and the tarsi are yellowish-white, like the

trochanters and cox, and the other parts of the legs vermilion-red; but in darker

examples the tibie are fusco-testaceous or fuscous, or have the basal half rufous, The

elytra are more or less ochraceous, with some of the nervures red. The anterior

femora are furnished beneath with an irregular row of sete, in addition to the long

fine hairs. The anterior trochanters have two clusters of setee beneath. The prosternal

spines are acute.

Twenty-eight specimens have been seen, one only of which is from Mexico, and that

very much discoloured.

5. Saica erubescens, n. sp. (Tab. XI. figg. 5, 5a, ¢.)

Elongate, very narrow, slender; dilute whitish-stramineous, the femora with a rather broad annulus at the

tip, the hind pair also with a faint annulus a little beyond the middle, the hind angles of the pronotum,

and the elytra with the costa in part and some of the nervures towards the base, rosy-red; the body,

legs, and antenne thickly clothed with very long, fine, erect, whitish hairs, the anterior femora also

furnished beneath with an irregular row of scattered sete. Head swollen behind the eyes, the latter

large and prominent. Pronotal spines acute and exceedingly elongate, projecting a little forwards and

outwards, as long as the backwardly-directed scutellar spine; post-scutellum with two spines—the

anterior one short and blunt, the posterior one acute and about one-third the length of the scutellar

spine. Legs very slender. Prosternal spines acute and visible from above.

Length (to tip of the elytra) 84, breadth 1,1, millim. (¢.)

Hab. Panama, Bugaba (Champion).

One specimen. Allied to S. tibialis, Stal; but much smaller and narrower than the

male of that insect, and with more slender limbs. The legs are whitish, with a dilute

rosy-red annulus at the apex of each of the femora, the posterior pair also having a

faint median ring.

p. 124, and iv. p. 91.

St&l included in this genus a single Tropical-American species, which is now known

to extend as far north as the Mexican State of Tabasco; a second very distinct form

from Panama is here added. The genus is easily recognizable by the three long spines

on the anterior tibie, the anterior femora also having a double row of spines. These

spines, like those on the underside of the head, arise from conical prominences. Most

of the specimens obtained by myself were beaten from the pendent withered leaves of

various musaceous plants.

Found in numbers at Senahu and Las Mercedes. This insect is usually testaceous,

but the head, thorax (the disc of the anterior lobe of the pronotum excepted), and

scutellum are in a few examples more or less piceous or black. The connexivum in

fresh specimens is stained with carmine-red. The basal joint of the antenne is blackish

at the tip, and in the males clothed with very long fine projecting hairs. The

anterior femora are armed beneath with a row of very short spines, with about five

longer spines intermixed, and they also have a row of long spines in front. The

anterior tibie have three long curved spines on their basal half externally. The anterior

trochanters and coxe, the underside of the head, and the front of the prosternum are

also armed with spines. The femora usually have a narrow fuscous or blackish annulus

before the tip, but this is not always distinct. The scutellum and post-scutellum are

each armed with a long erect spine, and there is a very short spine just in front of the

post-scutellar one. Twenty-seven specimens have been received.

2. Tagalis seminigra, n. sp. (Tab. XI. fig. 7, 2 .)

Elongate, slender, shining, very sparsely pubescent; black or piceous, the basal portion of the head and the

disc of the anterior lobe of the pronotum sometimes reddish; the abdomen ochraceous, with the base

beneath and the middle of the dorsum blackish, and the connexivum carmine-red; antenna: with joint 1

broadly black at the base and more narrowly so at the apex, and for the rest flavous, the other three

joints brownish; legs with the femora and the base of the tibie black and for the rest flavous; anterior

cox and trochanters piceous, the intermediate and hind pairs flavous; elytra with the nervures and their

immediate vicinity fuscous, for the rest pale ochraceous; the femora with a few very fine, long, projecting

hairs. Head with two spines on each side beneath, and the prosternum with a still longer spine on each

side in front; eyes large; antenne as long as the body, joint 1 about as long as 2 and 3 united, clothed

with very long fine projecting hairs in the male, 2-4 decreasing in length. Pronotum almost smooth, with

the posterior lobe broadly and deeply sulcate down the middle anteriorly. Scutellum and post-scutellum

each armed with a very long erect spine, the post-scutellar one preceded by a short spiniform prominence,

Intermediate and hind legs very long and slender. Anterior femora armed beneath with a row of very

short spines, with five longer spines intermixed, and with a row of six or seven spines in front, these latter

becoming longer towards the apex of the femur. Anterior tibie with three long, curved spines on their

basal half externally.

Length 5-6, breadth Z-1 millim. (¢ @.)

Hab. Panama, Bugaba (Champion).

One male and three females. More slender than 7. inornata, with the femora and

Subfam. CHRY XINAL.

The single genus referred to this subfamily cannot be included in any of the groups

of Reduviide as tabulated by Stal. It differs from the Acanthaspidine in the absence

of ocelli, from the Tribelocephaline in the very much less developed membrane, and

from the Saicine in the short basal joint of the antenne. The presence or absence o

ocelli must be regarded as of primary importance in the systematic arrangement of the

Reduviids *.

* Stal places the monotypic South-American genera Vescia and Belminus, which are without ocelli, amongst

the Acanthaspidine, though in his Tables he uses the presence of ocelli as one of the principal characters of that

subfamily !

post-ocular portions rounded externally and shorter than the eyes; antenniferous tubercles small,

not prominent; eyes coarsely faceted, rounded, occupying the whole of the sides of the head in front;

antenne inserted close to the eyes, joint 1 rather stout, not longer than the head, 2 more slender than,

and twice as long as, 1, 3 and 4 very slender, 3 shorter, and 4 a little longer, than 2; rostrum very

stout, short, joints 1 and 2 subequal in length, 3 short and triangular. Pronotum broader than long,

deeply sulcate down the middle, the lobes separated by a deep transverse groove; the anterior lobe

shorter than the posterior lobe and about as wide as the head with the eyes; the posterior lobe broad,

the nervures enclosing it uniting posteriorly and one of them extending thence to the apex. Abdomen

rounded at the sides, the connexivum extending outwards to some distance beyond the elytra. Anterior

cox moderately prominent, contiguous. Legs rather short, moderately stout, the anterior femora

unarmed and feebly incrassate, the tarsi 3-jointed. Body obovate, depressed, tomentose. .

do. Moderately elongate, rather broad, shining ; black, the anterior lobe of the pronotum and the scutellum

partly piceous ; the corium flavous, with nearly the apical half nigro-piceous; the clavus with the basal

half piceous and the rest flavous; the membrane whitish, with a large oval spot in the cell and a broad

lunate patch at the apex nigro-fuscous; the connexivum in great part flavous, the apex only of each

segment black ; the antenne with joints 1 and 2 ochreous, and the others fuscous; the legs (including

the cox) ochreous; the body, legs, eyes, antenne, corium, and clavus somewhat thickly clothed with

very long, fine, erect, pallid hairs, the hairs on the body and elytra arising from very minute punctures.

Antenne rather more than half the length of the body. Pronotum strongly constricted at the sides; the

anterior lobe obliquely wrinkled on each side of the median groove; the posterior lobe broadly depressed

in the middle, and also depressed on each side near the hind angles, the median groove sharply defined ;

the anterior angles unarmed.

Hab. Panama, David in Chiriqui (Champion).

Two males, both in a perfect state of preservation.

Subfam. STENOPODINA.

This subfamily of Reduviide is chiefly characterized by the thickened, porrect basal

joint of the antenne, the other joints being very slender and folding longitudinally

backwards beneath the head and first antennal joint, and by the presence of a sharply

defined discal area on the elytra. In two of the Central-American forms the second and

third joints of the anterior tarsi are more or less fused into one, but no importance

can be attached to this character.

This genus contains about a dozen described species, all but one or two of which are

American. It is easily recognizable by the spiniform prolongation of the basal joint

of the antenne, this latter being stout and rigid and extending beyond the point of

insertion of the second joint, the joints 2-4, which are very slender, folding backwards

in repose and received (with the rostrum) in the groove along the underside of the

truncate in the middle, leaving the terminal genital segment very narrowly exposed. The

abdomen in the female is gradually narrowed behind, and extends to far beyond the

elytra; it has the terminal ‘genital segment produced into a long caudiform process,

and the fifth ventral segment very deeply emarginate at the apex. The venter is

obsoletely canaliculate down the centre in both sexes. ‘The head has a row of stout

Very like D. hirticornis and similarly coloured, but sometimes with the head and the basal joint of the antenns

paler; the pronotum with the median space between the two carine usually infnscate ; the femora and

tarsi more or less fuscous; the tibice flavous, each with the base and apex fuscous or blackish, the anterior

the anterior tarsi have the second and third joints separated by a distinct suture.

This insect closely resembles D. semicolon, Stal, the type of which is before me*;

but it is smaller and less elongate, and has shorter legs, smaller eyes, a shorter third joint

to the antenna, less acute anterior angles to the pronotum, and the frontal processes

(jugee) stout to the tip.

The only known American representative of this subfamily occurs within our limits ;

the other five genera are confined to the tropical regions of the Old World.

NALATA. 191

Two of the species originally referred to it were subsequently transferred by Stal

to his genus Microlestria. The Nalate differ inter se in the size and arrangement

of the tubercles on the anterior lobe of the pronotum, as well as in the relative length

of the basal joint of the antenne and the form of the scutellar process. The colour is

more or less variable. The head has three prominent, conical, setiferous tubercles on

each side beneath. The femora are asperate and setose; the anterior pair are strongly

incrassate and armed beneath with two rows of short spines, amongst which are a few

longer and stouter ones. The anterior tibiz are armed with a row of short fine spines,

sometimes (XV. nigrescens) with stouter and longer spines intermixed. ‘The anterior

trochanters are armed with a stout spine.

Anterior lobe of the pronotum with two larger prominences or tubercles,

1. Nalata quadrituberculata, n. sp. (Tab. XI. figg. 23, 23a, 3.)

Moderately elongate, rather broad, fuscous or nigro-fuscous, the under surface slightly mottled with ochreous,

the connexivum with the apex of each segment ochreous; the elytra with a large common patch adjoining

the apex of the scutellum, and a spot at the base of each of the two inner cells of the membrane, nigro-

fuscous ; the femora, tibic, and rostrum more or less distinctly annulated with ochreous; the antenne,

rostrum, legs, and body set with long, scattered, bristly hairs, the body and corium also sparsely clothed

with short, stout, curled, decumbent, ochreous or rusty-brown hairs. Head with moderately prominent

tubercles above, the ocelli prominent, the eyes large and prominent; antenne elongate, joint 2 nearly

twice as long as 1, 3 longer than 2, 4 about half the length of 3. Pronotum with the anterior lobe

rather prominent ; the posterior lobe moderately dilated, with indications of one or two oblique ridges on

each side of the broad median depression. Scutellum with the apical process compressed and cristate, and

also tuberculate. Femora moderately asperate.

Length 83, breadth 24-3 millim. (¢ 9.)

Hab. Nicaraeva, Chontales (Junson); Panama, Volcan de Chiriqui (Champion).

Nine specimens. Easily distinguishable by its comparatively large size and dark

coloration, the strongly quadri-tuberculate anterior lobe of the pronotum, the cristate

scutellar process, and the common black patch on the inner portion of the elytra towards

the base. Viewed in profile, the compressed scutellar process appears to be arcuately

dilated upwards. <A specimen from Chiriqui is figured.

2. Nalata nigrescens, n. sp. . (Tab. XI. figg. 24, 24a, 2.)

Very like NV. quadrituberculata, but differing from it as follows:—The corium and clavus uniformly nigro-

fuscous or black, the membrane black; the four tubercles on the disc of the anterior lobe of the

pronotum much less prominent, and the smaller tubercles inconspicuous; the scutellar process broadly

ochreous at the tip, rather stout, and not cristate ; the antenns: more elongate ; the eyes larger and a little

more prominent; the anterior tibia with a row of six stouter spines interspersed amongst the fine ones.

Length 83-10, breadth 24-33 millim. (¢ 9.)

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

One pair. At first sight, this insect appears to be nothing but a darker form of

N. quadrituberculata, with which, however, it cannot be associated. ‘The two tubercles

on each side of the disc of the anterior lobe of the pronotum, formed by the oblique

sulcature of the eallosittes, are much less prominent than in that species, the inner

one being almost obsolete, whereas both of them are very prominent in JN. quadri-

tuberculata. The spines on the anterior tibie are also coarser, and the scutellar

process differently shaped.

8. Nalata irrorata, n. sp. (Tab. XI. fig. 26, 3.)

Broad, sordid ochreous, slightly mottled with fuscous, the sides of the head behind the eyes, the anterior lobe

of the pronotum in the middle behind, and the flattened portion of the scutellum fuscous; the corium

dilute fuscous, mottled with whitish, the apex broadly fuscous; the membrane fuscous, mottled with

ochreous, the two inner cells each with a blackish mark at the base; the connexivum broadly banded

with fuscous or nigro-fuscous ; the antenne with joints 1 and 2 ochreous, 2 annulated with fuscous,

3 and 4 fuscous; the scutellum with the margins and apical process pale; the body beneath much mottled

with fuscous; the femora with a single blackish annulus near the base; the anterior tibie triannulated,

and the other tibia quadri-annulated, with black or fuscous; the rostrum ochreous, annulated with

fuscous; the antenne, rostrum, legs, and body set with long, scattered, semierect bristly hairs, the

body and corium also sparsely clothed with short, stout, decumbent, curled, ochreous hairs, Head

with moderately prominent tubercles above, the ocelli very small ; antennz moderately long, joint 1 short,

about half the length of 2, 3 and 4 very slender, 3 as long as 1 and 2 united, 2 and 4 subequal in length.

Pronotum with the anterior lobe strongly gibbous, the callosity on each side of the median groove

suleate and divided into two indefinite prominences, the scattered tubercles small and not prominent ;

the posterior lobe strongly dilated at the sides posteriorly, depressed in the middle, without definite ridges

on the disc, their position indicated in front by small tubercles, the lateral margins asperate. Scutellum

with the margins raised, the apical process rather stout. Femora strongly asperate.

Length 7, breadth 22-24 millim. (¢ @.)

NALATA. 193

Hab. Panama, Bugaba (Champion).

Three specimens. Very like W. setulosa, but broader and more robust, with the

corium and membrane mottled with paler colour, the basal joint of the antenne shorter,

and the scutellar process stouter and less compressed; the anterior lobe of the

pronotum is more gibbous, the two callosities being each divided into two prominences,

and the posterior lobe is without definite ridges. NV. irrorata is also closely allied to

the Brazilian WV. aspera, Stal (the type of which is before me) ; but in the latter the

membrane is uniformly nigro-fuscous, with the base only pale, the anterior lobe of

the pronotum has two converging rows of conspicuous whitish tubercles in front, and

the head is not so abruptly constricted behind.

4. Nalata spinicollis, n. sp. (Tab. XI. figg. 27, 27a, 2.)

Rather broad, ochreous, the sides of the head behind the eyes, the posterior lobe of the pronotum, the middle

of the scutellum, and the elytra fuscous, the elytra with a spot at the inner apical angle of the corium

and one at the base of each of the two cells of the membrane black ; the connexivum broadly banded

with fuscous; the apical two joints of the antenne blackish; the underside of the body mottled with

fuscous ; the femora annulated with fuscous at the base; the tibie with the base, apex, and an annulus

before the middle, fuscous; the antenns, rostrum, legs, and body set with long, scattered, erect or

semierect, bristly bairs or sete, the body above and beneath, and the corium, also very sparsely clothed

with short, stout, decumbent, curled, ochreous hairs. Head armed above with numerous stout conical

setiferous tubercles, the two between the ocelli, the two on cach side near the eyes, and the one in the

centre in front being very conspicuous, the latter bearing two sete, the ocelli small and widely separated ;

antenne reaching to a little beyond the hind angles of the pronotum, joints 1 and 2 rather stout, 2 one-

half longer than 1, 3 and 4 very slender, 3 nearly one-half longer than 4. Pronotum dilated behind ;

the anterior lobe gibbous on the disc on each side of the broad median sulcus, and armed with numerous

very prominent, stout, conical, setiferous tubercles—about nine on each side, three of which are marginal ;

the posterior lobe with indications of two anteriorly converging ridges on the disc, these being limited in

front and behind by a setiferous tubercle; the hind angles rather sharp. Scutellum with the margins

raised and tuberculate, the apical process rather stout and also tuberculate above. Femora strongly asperate.

Length 7-74, breadth 23-24 millim. (2.)

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

Three specimens. This species is allied to WV. setulosa, Stal, but differs from it, and

from all others of the genus, in the very prominent, stout, conical tubercles on the head

and anterior lobe of the pronotum, these being much more conspicuous than in

N. aspera, Stal.

The type of this insect is before me. It is very like NW. setulosa, but the pronotum

is less widened behind, and the conical tubercles on the anterior lobe are more numerous

and form two well-defined series on each side of the disc and a row (of about eight)

along the lateral margins, each of the series on the disc being continued on to the

posterior lobe and there forming an oblique ridge. The antenne have their two basal

joints pale; the second joint is about one-half longer than the first. The femora are

strongly asperate. The tibie are without a dark ring at the base. The scutellar

process is flavous at the tip, and rather stout.

6. Nalata fuscipennis. (Tab. XII. fig. 2, 3.)

Nalata fuscipennis, Stal, Rio Jan. Hemipt. p. 80°; Enum. Hemipt. i. p. 120°.

Rather narrow, ochreous, the sides of the head behind the eyes, the depressed portions of the pronotum, the

middle of the scutellum, and the elytra (the costal margin at the base excepted) black; the connexivum

black, with a flavous spot at the apical angles of each segment; the tip of the scutellar process flavous ;

the two apical joints of the antenne fuscous; the body beneath much mottled with fuscous, the basal

half of the abdomen almost entirely black; the femora and tibiz more or less annulated with fuscous,

the posterior tibie pale at the base; the body, legs, and antenne set with long scattered bristly hairs, the

body and corium also sparsely clothed with short decumbent, curled, ochreous hairs. Head armed above

with short, subconical tubercles, the ocelli small and not very widely separated; antenne as in NV. spini-

collis. Pronotum moderately dilated behind ; the anterior lobe armed on each side of the median sulcus

with two rows of conical tubercles, those of the inner row closely placed and about five in number, and

with an irregular scattered marginal row of similar tubercles, the four rows on the disc being each con-

tinued on to the posterior lobe and there forming an oblique ridge; the hind angles obtuse and a little

swollen. Scutellum with the margins raised and tuberculate, the apical process neither thickened nor

compressed at the tip. Femora moderately asperate.

Length 6-63, breadth 2 millim. (d.)

Hab. Panama, Tolé (Champion).—Co.tomBia, Bogota? ; BraziL, Rio Janeiro} 2,

Two specimens. Very like WV. rudis, but with the femora less strongly asperate, and

the anterior lobe of the pronotum with fewer and less regularly arranged tubercles at

the sides, the tubercles in V. rudis forming a distinct marginal row. In WV. fuscipennis

the series of five tubercles on each side of the median sulcus are very conspicuous; the

second row is shorter, and formed by three tubercles; the marginal row is more or

less irregular. One of Stal’s Colombian examples has been examined.

Found in plenty in Chiriqui. This species varies a good deal in colour, the

pronotum and scutellum being sometimes almost entirely fuscous. The antenne have

their first joint pale, and a little more than half the length of the second. ‘The small

setiferous, scattered, conical tubercles on the disc of the pronotum are so arranged as

to form two series on each side of the broad median sulcus, these being each continued

as an oblique carina on the anterior portion of the posterior lobe. The scutellum has

the margins raised and tuberculate; the apical process is compressed and slightly

may be separated from Nulata have not been fully noticed by Stal: the intermediate,

as well as the anterior, femora are incrassate and shortly spinose beneath; the scutellar

process is short; and the eyes are small. The two basal joints of the antenne, the

legs, and body are sparsely set with erect or semierect sete, which are more or less

clubbed at the tip, these being very long and conspicuous in UM. levis.

Stal’s type of this insect is obscure flavo-testaceous in colour, with the head,

thorax, scutellum, femora, and marginal abdominal spots obscure fuscous. In all the

Guatemalan and Mexican specimens before me, and also in some of those from

Chiriqui, the anterior lobe of the pronotum is ochraceous; the others from Chiriqui

agree with Stal’s description. The corium in light-coloured specimens has the base

or entire inner part pale flavous, but in the dark individuals it is entirely fuscous.

The legs vary in colour. The scutellar process is short and rather stout. Our

specimens vary from 4-54 millim. in length. The type of MW. fuscicollis has been

communicated by Dr. Aurivillius. A specimen from Zapote is figured.

two basal joints rather stout, the others very slender, joint 2 nearly twice as long as 1, 3 and 4 subequal

in length, each much shorter than 2. Pronotum with the longitudinal median sulcus, as well as the

transverse one, very deep, the sete on the anterior lobe arising from inconspicuous raised points, the

posterior lobe feebly transversely rugose in the central depression, the thickened anterior angles rather

prominent. Scutellum shortly and acutely produced at the apex. Corium with the discal cell obliquely

and narrowly extended on to the inner basal portion of the membrane.

ARADOMORPHA, n. gen.

Head small, convex, cylindrical, grooved down the middle in front, the antero-lateral portions forming two

stout, downwardly curved, anteriorly converging processes, these being as long as the unarmed, declivous,

anteriorly widening antenniferous processes, which equal the eyes in length; the post-ocular portion

short, rounded externally ; the ocelli placed near the eyes and very widely separated ; the eyes (viewed

laterally) transverse, coarsely faceted, moderately large ; antenne short, inserted midway along the sides

of the ante-ocular portion of the head, joints 1 and 2 stout, 3 and 4 slender, 1 very short, about one-fifth

the length of 2, 2 nearly as long as 3 and 4 united, the latter subequal; rostrum short and stout, joint 2

elongate, 3 short. Pronotum broad, transverse, emarginate in front and unemarginate behind, divided by

a deep, sinuous, transverse sulcus into two lubes of nearly equal length, the lateral constriction deep; the

anterior lobe narrower than the posterior lobe, with indications of four sinuous ridges, which impinge on

the transverse groove. Scutellum triangular, the apex produced into a short, stout, horizontal, spiniform

process. Elytra ample, reaching the apex of the abdomen; corium coriaceous; membrane largely

developed, the inner basal cell narrow, the outer one much longer and broader and connected posteriorly

with a large pentagonal cell, the inner nervure of the first cell continued downwards to beyond the apex

of the corium. Abdomen( 3) with the connexivum broad and extending completely round the apex. Legs

short and stout; anterior femora strongly, the intermediate femora moderately, incrassate, each armed

with two rows of widely scattered, short spines beneath ; tibie with a short spine at the outer apical

angle, the anterior and intermediate pairs denticulate within ; tarsi 2-jointed, the claws simple. Body

robust, broad, obovate, flattened above.

The single species referred to this genus has very much the facies of an Aradid; it

is allied to Epirodera, Westw. (nec Signoret). It differs from the Acanthaspidine, as

defined by Stal, in having all the tarsi 2-jointed.

This Tropical- American genus includes numerous closely-allied species, chiefly differing

inter sé in the form of head and eyes, and in the disposition of the ochreous markings

on the elytra. ‘The femora are armed with a short spine on the inner and outer sides

at the apex beneath; the inner apical portions of the tibiee, and the anterior trochanters

in front, are densely clothed with fulvous hairs; the anterior and intermediate tibie

have an elongate spongy fossa at the apex beneath ; the metasternum, and the venter to

a greater or less extent, is sharply carinate down the centre. In the females the sixth

segment of the abdomen is truncate at the apex, and the two genital segments are

exposed, the first being large and trapezoidal and the second small.

198 HEMIPTERA-HETEROPTERA.

Many of the Tropical-American forms described by Walker under the genus Reduvius,

and some of his Pirates, belong here*. The various species are found under bark,

one of them being a very widely distributed and common insect in Tropical America.

The Central-American forms may be separated thus :—

a. Posterior lobe of the pronotum transversely rugose ; head with the lateral

post-ocular portions nearly twice as long as the eyes, the latter promi-

nent; membrane with the nervures more or less bordered with ochreous :

length over 18millm.. . 2... . oe . . . formicarius, Fabr.

We possess eight specimens of this species from within our limits, all but two of

them being from Chiriqui. Easily recognizable by its large size, the elongate post-

ocular portions of the head, and the transversely rugose posterior lobe of the

pronotum. ‘The coloration of the elytra resembles that of Z. litura, except that the

ochreous markings are almost obliterated at the base of the membrane. ‘The eyes are

prominent. The hairs on the head and pronotum are short, those on the legs being

very much longer. A specimen from Bugaba is figured.

This is one of the commonest Reduviids in the “ tierra caliente” of Tropical America,

ranging as far north as Durango. J. litwra is recognizable amongst its allies by the

comparatively large and prominent eyes and short head, the lateral post-ocular portions

of the head not longer than the eyes, ‘The nervures of the membrane are almost

entirely ochreous, and also bordered with that colour. The two specimens from

Ruatan Island are much discoloured, but they certainly belong here. An example

from Bugaba is figured.

Atoyac in Vera Cruz (H. H. Smith), Jalapa (Hoge), Temax in N. Yucatan (Gaumer),

Chiapas (Jf. Trujillo) ; Guatemata, Teleman in Vera Paz (Champion).

This species, one of the types of which is before me, is very like L. ditura, but differs

from it in having the eyes smaller and less prominent; the lateral post-ocular portions

of the head a little longer than the eyes; the membrane fuscous, with a triangular

ochreous patch on the outer margin adjoining the similarly coloured apex of the

corium, the nervures entirely dark ; the pronotum and legs clothed with longer hairs.

The venter, as in J. ditura, is sharply carinate almost to the apex. The seven specimens

from Yucatan have the body rufo-castaneous, and the legs and antenne rufo-testaceous,

probably due to immaturity; they are extremely like the Brazilian L. pallipes, Stal

(a type of which is before me), which, however, has a smaller and less elongate head,

and a more sparsely pilose pronotum. A specimen from Teleman is figured.

4, Leogorrus longiceps, n. sp. (Tab. XII. fig. 10, 2.)

Moderately elongate, nigro-piceous or black, the covered dorsal portion of the abdomen obscure ferruginous, the

elytra with a small patch below the base—extending over the apical half of the clavus, the extreme base

of the membrane, and the adjoining inner portion of the corium,—a small, subtriangular, posteriorly

excised patch on the outer portion of the membrane, and the apex of the corium broadly, ochreous, the

latter fulvous in some specimens; the second joint of the antenne and the tarsi sometimes fulvous; the

body, legs, and antenne clothed with very long, fine, fulvous hairs, the tibiee densely clothed with fulvous

hairs on the inner side towards the apex. Head comparatively elongate, very much longer than the

anterior lobe of the pronotum, the lateral post-ocular portions considerably longer than the eyes, the eyes

not prominent and rather small. Pronotum with the two lobes subequal in length, almost smooth, deeply

sulcate down the middle, the transverse median sulcus interrupted on each side of the central groove, the

anterior lobe shallowly obliquely sulcate on each side of the disc, the anterior angles rather prominent.

Scutellar process short, curved upwards at the tip. Abdomen not extending beyond the apex of the elytra

in the male. Venter sharply carinate at the base, the carina gradually becoming evanescent towards

the apex.

Length 123-134, breadth 43-5 millim. (¢ 9.)

Hab. Mexico, Orizaba (Bilimek, in Mus. Vind. Ces.); Guatemata, El Reposo,

Six specimens, four of which are from Guatemala. Very like L. venator, Stal, with

which it was confused in the Vienna Museum collection; but differing from that

species in having a smaller ochreous patch on the basal portion of the elytra and in

the more elongate head, the post-ocular portions of the latter being much longer than

the eyes. It is also a little larger and more elongate. In fresh specimens the

connexival segments have each a patch of pallid appressed pubescence. L. (Reduvius)

zanthospilus, Walk., from Ega, is an allied form; it has the ochreous post-basal patch

reduced to a spot on the corium, the apex of the latter black, &c. A specimen from

El Reposo is figured.

LEOGORRUS. 201

5. Leogorrus interruptus, n. sp. (Tab. XII. fig. 12, ¢.)

Moderately elongate, black or nigro-piceous, the elytra with several spots below the base—one on the clavus,

one on the corium, and two or three on the base of the membrane,—a patch on the apical portion of the

corium before the tip, and a subtriangular, posteriorly-excised mark on the membrane connected with it,

ochreous; the tarsi sometimes fulvous; the body, legs, and antenne sparsely clothed with long, fine hairs,

the tibie thickly clothed with fulvous hairs on the inner side towards the apex. Head moderately long,

the post-ocular portion convex and slightly longer than the eyes, the latter rather prominent. Pronotum

as in LZ. longiceps. Scutellar process slightly curved upwards at the tip. Venter sharply carinate almost

to the apex, the first three sutures with a row of coarse punctures.

Length 113-13, breadth 41-44 millim. (d 9.)

Hab. Panama (Boucard), David (Champion).

Three specimens, two of which are in a bad state of preservation. Very like

LL. venator, but with the eyes a little larger and more prominent (approaching L. litura

in this respect, but with the post-ocular portion of the head longer), the tip of the

corium black, the ochreous patch at the base of the membrane divided up into spots.

6. Leogorrus fasciatus, n. sp. (Tab. XII. fig. 13, 3.)

Moderately elongate, broad, nigro-piceous or black, the elytra with a common, broad, strongly angulated, trans-

verse ochreous fascia below the base—the ochreous coloration extending over the apical half of the clavus,

the inner and outer portions of the corium to the tip, and the basal and outer portions of the membrane,—the

membrane in great part fuscous, with the apex narrowly pale; the tarsi, the second joint of the antenne,

and the intermediate and hind tibie at the apex, more or less fulvous; the body, legs, and antenne

somewhat thickly, the venter sparsely, clothed with very long, fine, fulvous hairs, the tibise densely clothed

with fulvous hairs on the inner side towards the apex. Head moderately elongate, very much longer than

the anterior lobe of the pronotum, the lateral post-ocular portions considerably longer than the eyes, the

eyes not prominent and rather small. Pronotum with the two lobes subequal in length, almost smooth,

deeply sulcate down the middle, the transverse median sulcus interrupted on each side of the central

groove, the anterior lobe distinctly obliquely sulcate on each side of the disc, the anterior angles rather

prominent. Scutellar process short, compressed, subhorizontal. Abdomen broad, extending beyond the

elytra in both sexes, rounded at the sides. Venter sharply carinate at the base, the earima gradually

becoming evanescent towards the apex, the sutures smooth.

Length, 3 134, 9 153, breadth 53 millim. (d @.)

Hab. Guatemaua, San Gerénimo in Vera Paz (Champion).

One pair. Closely allied to L. picturatus, Stal (= Reduvius signatus, Walk., and

Pirates megaspilus, Walk.), from Colombia, but with the ochreous colour less extended

over the base of the membrane and forming a broad, common, strongly angulated

fascia; the present species is also larger, more elongate, and more hairy, and has a

longer head, less prominent eyes, &c. Stal’s type has been seen.

7. Leogorrus immaculatus, n. sp.

3. Dull nigro-piceous above, paler beneath, the connexivum and venter obscure ferruginous ; the legs piceous,

with the tarsi fulvous, the antenne with the second joint fulvous; the body, legs, and antenne very

sparsely clothed with long hairs, those on the head and pronotum shorter and erect. Head smooth,

narrow, the post-ocular portion convex and about twice as long as the eyes, the latter small. Pronotum

almost smooth, the oblique sulci on the anterior lobe very shallow; the transverse median sulcus, and also

the longitudinal-one, very deep. Elytra reaching the apex of the abdomen, immaculate.

Length 94-10, breadth 33-33 millim.

‘which were found in Chiriqui. It bears an extraordinary resemblance to some of the

large species of the Hymenopterous genus Pepsis, these insects, like the Spiniger,

frequenting decaying trees in forest-clearings. The second joint of the antenne is

the pronotal and scutellar spines are ochreous, with the base more or less black. The

type of S. flavispinus was from an unknown locality.

One female. This specimen nearly agrees with Herrich-Schaffer’s figure: the

pronotum has four red tubercles on the disc of the anterior lobe, as well as a lateral

tubercle on each side, and there are two similarly coloured oblique ridges on the dise

of the posterior lobe. The juge are bright red and tuberculiform. The anterior and

intermediate femora are asperate beneath and strongly incrassate. The venter is

sharply carinate almost to the apex. The apical joint of the hind tarsi is as long as the

two others united.

A well-marked Tropical-American genus, containing three closely allied species, two

of which are common to Ventral and South America. The name Macrophthalmus was

changed by Burmeister to Macrops, on account of its being preoccupied in Crustacea

(Latreille, 1829), he being unaware of the fact that Macrops had been used in

Reptilia (Wagler, 1830); the genus, therefore, still requires a new name. Both

Macrophthalmus and Macrops have been subsequently used in Coleoptera. These

insects live under the bark of decaying trees, in forest-clearings, and prey upon freshly

emerged Coleoptera &c. Our two species may be separated thus:—

Frontal tubercles (jugze) very prominent, oblique, and subconical, the tubercles

more or less uniting at the base and together forming a broad bifurcate

elevation; corium with a black A-shaped mark before the apex: body

but two of them being from Chiriqui. This insect is larger and more elongate than

M. pallens, and easily separable therefrom by the prominent horn-like frontal tubercies

and the differently marked corium. In some specimens the frontal tubercles are ionger

than in others, this being especially noticeable in the Panama examples. A specimen

from the Volcan de Chiriqui is figured.

A genus containing about twenty known species *, spread over the warmer parts of

both hemispheres. They are of large size, and some of them are stated to attack man,

the “great black bug” or ‘benchuca” of the pampas, mentioned by Darwin in his

‘Journal of the Voyage of the Beagle,’ p. 403 (1839), being the larval or pupal form

of a Conorrhinus. Prof. Ubler (Bull. U.S. Geol. & Geogr. Surv. i. p. 331) notes the

extended range of C. sanguisugus, Lec., and describes it as a blood-thirsty tenant

of beds in houses. C. dimidiatus has been seen by myself in Guatemala in suspicious

proximity to beds, though it was not actually observed in the act of blood-sucking.

The genera Meccus, Lamus, and Rhodnius, Stal, include closely allied forms, the last-

mentioned not being represented within our limits f.

In the typical form of this species the elytra have a very small black spot on the

disc of the corium, this being sometimes quite obsolete. ‘The variety maculipennis,

Stal, has the discal spot much larger, often forming a broad more or less interrupted

transverse fascia. The variety 6, of which a single specimen only has been received,

has the corium dark, with the exception of the outer margin at the base and a space

along the middle of the apical margin; this form is very like C. infestans (Klug)

(=renggeri, H.-S.) *, which has a stout, thickly pilose rostrum, with the first and third

joints nearly equal in length, the produced anterior portion of the head broader and with

the sides straighter, the connexivum black at the apex in both sexes, &c. In all the

varieties of C. dimidiatus the base of the clavus and the apex of the corium are infuscate

or black. The insect varies greatly in size, this being especially noticeable in the females,

the elytra in the largest of these not reaching as far as the apex of the sixth segment

and the connexivum being very broad. The single specimen seen from Honduras, a

female, is much longer than any of those received by us. We figure a male of the

typical form and a female of the var. maculipennis, Stal, both from Yucatan.

It is by no means certain that the insects from all these widely separated localities

really belong to one and the same species, and a description and figure of the Mexican

insect are therefore given, taken from the three females received from Forrer.

Prof. Uhler states® that the Mexican and Californian examples have the anterior

angles of the pronotum less produced, and that those from California (like ours) are

sometimes almost uniformly rusty-black. In the typical C. rubrofasciatus the

pronotum has the lateral margins entirely pale and the anterior angles strongly

produced, and the elytra have a reddish vitta on the clavus and a similarly-coloured

mark at the apex of the corium.

Two females. They differ from the type, now before me, in having the anterior

angles of the pronotum much more produced (instead of short, as in the type),

and the connexival segments maculate at the sides, as well as at the base. The upper

surface, the membrane excepted, is sparsely clothed (like the venter) with short,

decumbent, ochreous hairs. The whole of the nervures of the elytra, the margins

of the pronotum and several lines or vitta on the disc, and three longitudinal lines

on the head, are of a sordid or reddish-ochreous colour ; the two irregular transverse

reddish-ochreous marks on each of the connexival segments are in one specimen

united, so as to enclose a marginal black spot, but in the other they are completely

separated.

The three species of this genus are amongst the largest of the known Reduviids, and

all of them are from Mexico. Meccus is scarcely separable from Conorrhinus, merely

differing from it in the rather longer post-ocular portion of the head (exclusive of the

neck), and the more prominent tubercles on the anterior lobe of the pronotum. The

females (the only sex known to Stal when he described the genus) appear to be more

thickly pilose, and more rugose, than the males, and to have the elytra relatively

shorter than in Conorrhinus, extending to about the apex of the fifth segment.

This species, which appears to have been known to Stal from description only, is

evidently a close ally of MW. phyllosoma, but differs from it in having the hind angles of

The two Tropical South-American species referred to this genus by Stal differ from

Conorrhinus in having the antenne inserted very near the eyes (the portion of the head

in front of this point being three or four times as long as the antenniferous processes).

The Central-American species now added is intermediate in this respect, as are

Conorrhinus lignarius, Walk., and C. porrigens, Walk., which are nearly allied

congeneric forms.

two narrow, partly connected, angulated fascie black, the membrane with the entire inner half much

mottled with fuscous, and with a large similarly coloured patch at the base of the outer discal area; the

connexivum reddish-ochreous, each segment with the basal margin and a subquadrate median lateral patch

black ; the basal joint of the antenne ferruginous above; the femora each with a narrow annulus at the

apex, and the upperside more or less to near the tip, rufo-ferruginous; the legs and antenna pilose, the

three outer joints of the latter also with long fine projecting hairs. Head much shorter than the pronotum,

the anterior lobe stout, parallel, and a little shorter than the posterior lobe, the antenniferous processes

short, about half the length of the very large and prominent eyes, the post-ocular portion very short, the

ocelli large and prominent ; antenne with joint 1 about reaching the tip of the apical process of the head,

2 more than three times longer than 1, 3 and 4 decreasing in length ; rostrum with the apical third pilose,

joint 3 much shorter than 1. Pronotum hexagonal, deeply sulcate down the middle anteriorly; the

anterior lobe almost smooth, with two prominent, smooth, rounded tubercles on the disc and one on each

side posteriorly ; the anterior angles dentiform, oblique, strongly produced; the posterior lobe rugose,

with two anteriorly converging carine on the disc, these becoming evanescent behind and extending on

to the base of the anterior lobe in front; the hind angles rounded, raised, and moderately dilated.

Scutellum transversely rugose, with two posteriorly coalescent carine on the disc, the apical process

horizontal, stout, and rather short. Abdomen moderately dilated at the sides, rounded at the apex.

Legs moderately long : anterior and intermediate femora each armed on the underside before the apex with

two, transversely placed, short teeth ; posterior femora slightly swollen on the lower side before the apex.

Length 25, breadth 8} millim.

Hab. Panama, Bugaba (Champion).

One specimen. This species has very much the facies of Conorrhinus venosus, Stal;

but the head is much shorter, with the antenniferous processes short (the antenne, in

consequence, being inserted much nearer the eyes), the post-ocular portion very little

longer than the ocelli, and the eyes very large. It has a longer pronotum and a shorter

scutellar process than the South-American L. gentculatus (Latr.) (=corticalis, Walk.).

The red tubercles on the disc and sides of the anterior lobe of the pronotum resemble

those of Spiniger rubropictus.

labelled as having been found by M. Boucard at Panama. It has the head, thorax,

scutellum, meso- and metasternum, and nearly the apical half of the abdomen (the con-

nexival margins excepted), violaceous or ceruleous, the anterior lobe of the pronotum

being green on the disc. The elytra have the outer part of the corium broadly rufescent

and the inner portion testaceous; the clavus testaceous, with the apex white; the mem-

brane in great part black, with a transverse arcuate fascia a little below the base, and an

elongate, anteriorly truncated, stripe in the middle at the apex, white, the basal portion

being of the same colour as the inner part of the corium. The basal half of the venter

is bright rufous. The anterior legs have the femora entirely rufous, and the tibiz

testaceous, with the apex blackish externally. The intermediate and hind legs are

nigro-violaceous, with the femora broadly testaceous at the base and the tarsi fusco-

testaceous. The antenne are black, with the first joint entirely, and the second to near

the tip, testaceous. A Brazilian specimen ( ¢ ) before me, belonging to the Stockholm

Museum, merely differs from the Panama insect in having the posterior lobe of the

pronotum reddish.

A Tropical-American genus, with one or two representatives extending northwards

into the United States. Upwards of twenty different species are enumerated by

Lethierry and Severin, but many of the names are mere synonyms or wrongly placed

under Rasahus t+. These insects, owing to their large size and conspicuous markings

seem to have been great favourites with collectors. Eight species are here recorded

from Central America, one of which is treated asnew. The synonymy of most of them

is much involved, Walker having described many previously known forms under

new names.

This fine species is not uncommon in the forest region of the “ tierra caliente” of

Central America, numerous examples having been found by myself, both in Guatemala

and in Panama. All of them have the whitish stripe along the inner margin of the

membrane extending rather broadly across its base to near the apical margin of the

corium, this transverse marking not being shown in Mayr’s figure, though mentioned in

his description. The anterior lobe of the pronotum is sharply, and the posterior lobe

more feebly, margined at the sides. One of Stal’s specimens from Bogota has been

Apparently a common insect in Mexico. Prof. Uhler’ has called attention to the

colour-variation in this species, comparing it in this respect with Sirthenea stria

(carinata). ‘The head and pronotum are sometimes entirely rufous, sometimes entirely

black, or, usually, black, with the posterior lobe only of the latter rufous (¢horacicus,

Stal); the legs are generally rufo-testaceous, with the intermediate. and hind femora

broadly flavous at the base, but sometimes the reddish portions are almost entirely

black; the ochreous coloration at the base of the elytra varies in extent, usually

extending down the outer portion of the corium; the membrane, however, is constantly

black or blackish, with a large oval or rounded ochreous patch about the middle, and

sometimes with indications of a paler spot at the apex. The pronotum is entirely

rufous in the earlier stages of this species. One of Stal’s types of &. thoracicus has

been seen. <A specimen from Atoyac is figured.

We possess thirteen specimens of this species from within our limits. They vary a

little in the shape of the large ochreous spot on the membrane, this being sometimes

rounded in the females. The coloration of the legs appears to be much more constant

than in R. diguttatus. In one of the Guatemalan specimens the anterior lobe of the

pronotum is pitchy-red and the clavus is almost entirely pale. The outer portion of

the corium is constantly dark.

Dr. Bergroth, who has examined Fallou’s types, states (Rev. d’Ent. xi. pp. 262, 263)

that R. sipolisii, Fall.*=R. hamatus (Fabr.), and Lestomerus varipes, Fall.= Pirates

locality was given by Walker for Pirates indecisus 18 and P. contiqguus'*. One of

our insect perfectly agrees. A male from Tolé is figured.

Stal’s description of the Fabrician type of this species was made from a badly

mutilated, discoloured example, with the antenne, legs, (corium ?), and abdomen missing.

In the thirteen specimens obtained by myself in Chiriqui the head and pronotum have

an eneous or greenish-zeneous lustre; the scutellar process is whitish at the tip; the

elytra are black, with the inner margin of the corium at the base, an elongate mark

on the posterior half of the clavus, a similar mark on the adjoining portion of the

corium, a large transverse spot a little below the base of the membrane, a large

suboval spot at its apex, and a short, slender, curved streak immediately beyond the

apex of the corium, sordid white; the connexival segments are each broadly banded

with whitish, and the bases of the intermediate and hind femora are similarly coloured.

The spongy fossa on the underside of the apex of the anterior tibie is short, not nearly

reaching the middle. ‘The third joint of the posterior tarsi is a little shorter than the

other two united. These examples measure from 103-12 millim. in length, and 24-32

in breadth: Stal gives length 15, breadth 8 millim. A specimen from Bugaba is figured.

-* According to the description, this insect should have a small additional spot towards the middle of the

elytra.

Not uncommon in Chiriqui, whence we possess ten examples. The types of Stal’s

and Walker’s species have been seen. In this species the pronotum is opaque, often

with a slight violaceous lustre, with the sulci on the anterior lobe (except the median

one posteriorly) very shallow. The ochraceous or whitish elytral markings show little

sign of variation: there is a small spot adjoining the apex of the scutellum, a transverse

spot a little below the base of the membrane, and a short A-shaped streak near the

apex of the corium. A Chiriqui specimen is figured.

7. Rasahus bifurcatus, n. sp. (Tab. XIII. fig. 11, ¢ .)

Moderately elongate, opaque, nigro-piceous or black ; the elytra with a broad ochreous stripe extending along

the clavus and inner portion of the corium to beyond the base of the membrane, and then bifurcating

and continued for some distance along its inner and outer margins, the outer branch following the

direction of the outer nervure to near the tip and usually with a narrow ramus extending backwards

along the median nervure at its point of termination (forming a hook-like mark); the abdomen slightly

shining above, the connexival segments opaque, each with a broad ochraceous patch at the base; the

legs piceous or nigro-piceous, the intermediate and hind femora each with a flavous ring at the base, the

tarsi fusco-testaceous ; the antenne piceous, with the basal joint black and the tip of the second joint

ochraceous ; the head, pronotum, antenne, and legs with a few widely scattered, long, fine, projecting

hairs. Antenne with joints 2-4 subequal in length, 1 less than half the length of 2. Pronotum much

longer than broad, both lobes obsoletely margined laterally ; the anterior lobe rounded at the sides, twice

as long as, but much narrower than, the posterior lobe, the disc broadly and very shallowly trisulcate

down the middle and with two very shallow oblique sulci on each side, the sulci and the lateral margins

closely granulate, the median sulcus becoming very deep at the base; the posterior lobe closely and

conspicuously granulate, with the obtuse hind angles moderately prominent; the anterior angles

tuberculiform and very prominent. Scutellum granulate, the spiniform apical process compressed and

semierect. Elytra comparatively short, reaching to about the middle of the sixth abdominal segment in

the male and to a little beyond the apex of the fourth segment in the female. Abdomen oval, very much

wider than the pronotum, rounded at the apex in the female and broadly subtruncate in the male; the

connexivum broad, in the male extending broadly round the apex of the abdomen. (Pro-, meso-, and

metapleura granulate, the venter smooth. Anterior tibie with the spongy fossa extending to nearly

two-thirds of its length. Posterior tarsi with the third joint a little shorter than the two others

united.

members of the genus in the densely cinereo-pubescent head and anterior lobe of the

pronotum. The elytra have a rather large spot below the base (occupying the apex of

the clavus and a space on the adjoining portion of the corium), a transverse curved

fascia before the middle of the membrane, and a rounded spot at its apex, sordid

white. The pronotal sulci are very shallow.

Three specimens. Very like P. enescens, Stal (= reciproca, Walk.), from Brazil,

but differing from it in having the neck-like basal portion of the head longer and more

slender, the ocellar tubercle more raised, and the femora annulate. The differently

formed head will separate it from P. lugens.

3. Elongate, black; the pronotum with the anterior lobe, two small spots on the disc excepted, and a trans-

verse anteriorly excised, diamond-shaped patch on the dise of the posterior lobe, extending to the base, as

well as a large patch at each hind angle, extending forwards along the margin to the transverse median

sulcus, sanguineous ; the corium with the base, outer margin, and an irregular fascia before the apex,

extending upwards along the inner margin, sanguineous ; the meso- and metapleura each with one, the

propleura with two sanguineous spots; the connexival segments 1-5 each with a large patch, extending

Rhiginia, Stal, Ofv. Vet.-Ak. Forh. xvi. pp. 176, 181 (1859) ; Hem. Afr. iii. p. 102.

The genus Ectrichodia, as restricted by Stal in his later work, includes eight species,

all American, ranging from the United States to the Argentine Republic. Some of them

are variable in colour, and they differ sexually in the form of the head and eyes. The

females are almost always brachypterous f, and individuals occasionally occur with still

shorter elytra; they also differ from the males in having the head more dilated at the

sides behind the eyes, the eyes smaller, and the transverse median sulcus of the pronotum

placed farther back, so that the anterior lobe appears to be more gibbous in this sex.

* In the male of Ectrichodia venusta, Walk., from Brazil, the anterior and intermediate femora are toothed

in the male and unarmed in the female.

+ I have seen only one macropterous female of an Ectrichodia, a specimen of E. cruciata (Say), sent me by

Prof. Uhler.

ECTRICHODIA. 225

It is probable that the eyes in the male will be found to vary in size in different

individuals of the same species. The antenne are apparently 8-jointed, the usual third

joint being divided into two, and the fourth joint into four.

Capetillo (Champion); Nicaragua, Chontales (Janson); Costa Rica (Van Patten);

Panama (Boucard).

A very variable and widely-distributed species. In fresh examples the head, except

at the sides behind the eyes, the pronotum, the base of the elytra, and the connexivum

in great part, are bright sanguineous, this colour fading to testaceous. The pronotum

in some specimens has the transverse sulcus, and also the longitudinal one, more or less

spotted or marked with black (crucifera, Stal). The females sometimes have a large

black patch on each of the connexival segments; this form has only been seen from

Chontales. The legs are constantly black or piceous. The venter in some examples is

spotted or fasciate, in others in great part sanguineous, or entirely black. The name

crudelis being preoccupied in Ectrichodia in the wide sense, it was subsequently changed

by Stél; but as this genus is now restricted to a few American forms, this alteration

becomes unnecessary. Stal’s and Walker’s types have been seen. The specimens before

me vary from 123-21 millim. in length, and from 5-9 millim. in breadth. A typical

male from Panzos and a female of the var. crucifera from Teleman are figured.

It is perhaps an extreme form of the very variable EZ. crudelis, from which it differs in

having the eyes larger and more prominent in the male, and the sides of the head a

little more rapidly converging behind in this sex.

In the Vienna Museum collection there are two precisely similar females of an

Ectrichodia—one labelled “Mexico” and the other Cuba—which are somewhat

doubtfully referred to this species. They have the connexival segments broadly

banded with black, the elytra very short and fuscous in colour, the pronotum without

a transverse black spot on the disc of the posterior lobe in front, the legs in great

part pale (the apices of the femora excepted), the post-ocular portion of the head

broad, and the eyes small.

Subfam. HAMMATOCERINA.

This subfamily of Reduviide includes two American genera only. ‘They exhibit a

very remarkable structure in the antennee, not found in any other known Heteropterous

insects: the first joint is short and stout ; the second joint is very elongate, slender, and

flexible, and divided up into numerous short jointlets (23-28 in Hammatocerus, and

8-18 in Homalocoris); the third and fourth joints are more slender than the second,

subequal in length, and show traces of segmentation. The head is not at all prolonged

behind the prominent eyes, and the ocelli are placed between them. Laporte notes

that the antennal structure approaches that of the Blattide. —

These insects are found under the bark of decaying trees, some of them being

common in the forest-regions of Tropical America.

the hind femora to near the tip, as well as the others at the base, rufous. Stal?

is larger than H. luctuosus, and has the head and the anterior lobe of the pronotum

more finely granulate, and the base of the elytra more broadly whitish.

The Central-American specimens agree with the Bogota insect mentioned by Stal

(now before me), all of them having the anterior lobe of the pronotum partly flavous.

The colour of the pronotum is variable, the transverse black fascia on the posterior

lobe being sometimes obliterated or divided into two spots. In the South-American

examples the anterior lobe is sometimes black, as described by Fabricius and Signoret *.

The males have the last genital segment deeply emarginate on each side of the

produced median lobe, the latter being rounded at the apex; the claspers are long

and somewhat sinuous, and strongly hooked at the tip, the latter being blunt. The

females, like the males, have the venter very sparsely pilose.

An American genus ranging from Canada to the Argentine Republic, including a

large number of species, the majority of which are tropical. Eighteen are here recorded

from within our limits, four of them being described as new; A. ochropterus, Stal, and

A. rubrocinctus, H.-S., ave, however, included with some doubt. Many of the species

are so variable in colour that they can only be separated by the form of the terminal

genital segment of the males, or by the structure of the first genital (terminal dorsal)

segment of the females. In the males the apex of the last genital (ventral) segment,

which in several species is produced into a short process, is either armed with two long

spines—usually curved upwards and obliquely divergent (A. hirtipes, A. subpiceus, &c.),

but sometimes horizontal and laterally extended (A. flaviventris, &c.),—or has a single

long unarmed truncated process (A. /anipes); the long lateral hooks or claspers, which

* In the Stockholm Museum there is an Agriocoris, from the Amazons, which differs from our insect in

emargination (a character not indicated in Signoret’s or Stoll’s figures): this form is noticed by Stal in his

remarks on A. curvipes, and the name he suggests, A. fasciata, can be used for it.

are articulated to the upper inner edge of this segment, also differ in form according

to the species, these being sometimes angularly dilated on the inner edge (A. emargi-

natus) ; a second pair of very short claspers are visible in one species (A. emarginatus).

In the females the narrow first genital (last dorsal) segment is sometimes furnished

with a foliaceous, piriform or orbicular, appendage on each side, movable at the will

of the insect (A. verillarius, A. hirtipes, &c.); in others (A. flaviventris, A. pictipes,

&c.) the outer apical angles of this segment are simply bent downwards, so as to form

a small transverse or triangular plate; in others, again (A. subpiceus, &c.), the lateral

margins of this segment are quite simple and form an uninterrupted outline with

the connexivum ; the terminal genital segment is trapezoidal in shape and invisible

from above, the chitinous surface of it becoming ventral. The females, moreover,

differ from the males in having the ventral surface thickly pilose, and the posterior

tibiee compressed and sinuous before the apex, and furnished with a dense brush of

short bristly hairs on the upper edge beyond the middle. In the males the ventral

surface is sparsely pilose and the posterior tibize have a much shorter brush, sometimes

formed of a few scattered bristles only. The females have the power of exuding a

sticky fluid from the ventral surface, and probably from the tibia also: the hairs

on the venter are matted and stuck together with this substance in nearly all the

specimens examined. From what I have observed of the habits of one of the

largest species, A. vexillarius, which is quite common in forest-clearings in the “ tierra

caliente” of Chiriqui, this viscous fluid appeared to be used for the purpose of securing

a firm grasp of its prey—freshly emerged Longicornia, &c., nearly as large as itself—

during the process of suction. Dr. Sharp, however (Trans. Ent. Soc. Lond. 1892,

pp- 191-199), has recorded a curious fact in connection with the mode of deposition

of the eggs of an Amazonian Reduviid (possibly a species of Harpactorine or

Apiomerine), showing that this fluid is used for gumming them down on a leaf.

The foliaceous appendages of the females of A. vewillarius, &c., are bright sanguineous

in life, and very conspicuous, looking like two red flags waving about, as the insect

runs over the surface of fallen timber in search of its prey. These appendages, like

the more or less expanded and similarly-coloured sixth dorsal segment of the males of

the same species, often fade after death to flavous or even black. The anterior and

intermediate tarsi are short and retractile, fitting into a groove along the outer face of

the stout, broad tibie.

Some of the smaller forms are found upon flowers or herbage. I am unacquainted

with the larva or pupa of any of the species of the genus.

appendages, 2; 16, part of posterior leg, 9; 2, sixth dorsal segment, ¢; 2a, last

genital segment, ¢ ; 26, ditto, from within ; 2 ¢, ditto, in profile.)

Broad, robust, shining, black, the corium, except at the base narrowly, brownish-ochreous or flavescent, the

membrane smoky hyaline, the antenne ferruginous, with the basal one or two joints sometimes infuscate,

the connexival segments bordered with ochreous in front, the legs entirely black or with the apices of the

femora and the tibie in part rufous; the dilated portion of the sixth dorsal segment in the male and the

foliaceous appendages of the female bright sanguineous in life (often discoloured in dried specimens),

the narrow basal portions of the latter flavescent ; the body sparsely clothed with erect black sete, the

elevated portions of the anterior lobe of the pronotum, the entire posterior lobe, the base of the scutellum,

and also that of the corium, the pleura and sterna, densely, and the head more sparsely, clothed with

short cinereous or fulvo-cinereous decumbent pubescence, the other parts of the body also finely

pubescent, the connexival margins with a dense fringe of short black hairs; the legs densely setose.

Antenne with joints 1 and 2 equal in length, 3 nearly twice as long as 2,3 and 4 equal. Pronotum

with the base feebly sinuate on each side near the hind angles. Elytra longer than the abdomen in

both sexes, the connexival margins sinuate. Legs moderately stout, the intermediate and hind femora

thickened before the tip.

3. Terminal genital segment with two long, upwardly curved, divergent spines; the claspers moderately

long, abruptly bent inwards at the middle; sixth dorsal segment produced posteriorly into a broad,

laterally dilated, foliaceous plate, which is emarginate in the centre at the apex ; posterior tibive with a

short brush of hairs on the upper edge beyond the middle.

2. First genital segment with a very large, elongate, broadly piriform, foliaceous appendage on each side;

venter densely pilose; posterior tibize compressed and sinuous before the apex, and with a long dense

brush of short bristly hairs on the upper edge beyond the middle.

Length 21-26, breadth 74-104 millim.

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

Found in abundance by myself in forest-clearings in Chiriqui, in 1882-83. This

large and conspicuous species is closely allied to the South-American A. pilipes (Fabr.),

differing from it in having the foliaceous appendages of the females much more

elongate and about twice as large as in the corresponding sex of that insect, a specimen

of which has been communicated by Dr. Aurivillius for comparison. In the males

these appendages are shorter and completely connate, forming a broad, laterally dilated

plate round the apex of the abdomen. The specimens are quite constant in colour

(the variation noticed being merely due to discoloration after death or to immaturity),

except that the legs are sometimes partly rufous. The present species superficially

resembles A. lanipes, which, also, is quite constant in colour, so far as the Central-

American examples are concerned. Upwards of 100 examples of A. verillarius have

been examined.

Hab. Nicaracua, Chontales (Janson: 2); Costa Rica, Rio Sucio (Rogers: 2);

Panama, Colon (Boucard: 3 9 )—AMazons.

The five specimens from Central America referred to A. hirtipes agree very well with

the figures of Stoll and Hahn, except in colour: the four females have a triangular

sanguineous patch in the middle of the corium towards the apex, this being less

distinct in the Panama example; the male, which is very much smaller, has the

posterior lobe of the pronotum piceous and the light-coloured patch on the corium

much more extended. The females have the foliaceous appendages moderately large

and suborbicular in shape, with the base narrow. The males have the sixth dorsal

segment dilated and produced, with the apex testaceous or sanguineous and somewhat

rounded ; the two spines at the apex of the terminal genital segment are long, widely

divergent, and curved upwards, and hooked at the tip; and the claspers are stout, and

abruptly bent inwards at the middle. Stl sinks A. hirtipes (Fabr.) as synonymous with

A. pilipes (Fabr.); but the specimens sent me by Dr. Aurivillius from the Stockholm

Museum under these names (apparently in Stal’s handwriting) seem to me to belong to

different species, the female of A. pilipes having the foliaceous appendages broader at

the base, as well as differing in the colour of the elytra, &c. Stal, moreover, treats the

A. hirtipes of Fabricius and the A. hirtipes of Hahn as different species, renaming

the latter dA. nigrilobus, but in this I cannot follow him. The specimen labelled

A. hemorrhoidalis in the Stockholm Museum, a male from the Amazons, has the

intermediate and hind legs in great part, the anterior knees, and the abdomen

testaceous, the latter with the apex bright sanguineous.

flavescent beneath. The females have the foliaceous appendages moderately large

and rounded, with the base narrow. The males have the sixth dorsal segment dilated

and produced, with the apex more or less testaceous and subtruncate; the two spines

at the apex of the last genital segment are long, widely divergent, curved upwards, and

feebly hooked at the tip; and the claspers are long and slender, and abruptly bent

inwards at the middle. A. elatus is very closely allied to A. hirtipes, but it is more

shining and more sparsely pilose; the foliaceous appendages of the female are smaller,

and the claspers of the male are more slender. The thirty-six specimens seen only

vary in the colour of the elytral patch, this fading from sanguineous to pale ochreous.

A. repletus, Uhler (?= occidentalis, Glover), from California, is a somewhat similarly

coloured form, and perhaps a variety of the present species.

There are two specimens of this species in the Vienna Museum labelled as from

“Mexico”; this locality is almost certainly incorrect, but as the species may occur in

the State of Panama, it is included here. A. ochropterus, the type of which is before

me, is nearly allied to A. elatus, but it is less elongate (appearing relatively broader),

the corium is pale ochreous, with the extreme base only darker, the membrane is

quite pale and subhyaline, the antenne are ferruginous, the head is comparatively short,

and the propleura are thickly clothed with pale shaggy pubescence; the female, more-

over, has much larger foliaceous appendages, and the male has the sixth dorsal segment

more broadly extended round the apex of the abdomen. In two of the three specimens

seen the posterior tibie, except at the apex, and the apices of the posterior femora are

rufous or testaceous. The males have the two spines at the apex of the terminal

segment a little shorter than in the same sex of A. elatus or A. hirtipes; the claspers

are more slender than in A. hirtipes, and shorter than in A. elatus.

APIOMERWUS. 237

Of this species seven specimens were captured by myself in Chiriqui. It is easily

recognizable by its large size and robust build, in connection with the dense shaggy

pallid pubescence of the head, thorax, pleura, and sterna, and the unilobate last genital

segment of the male. In the Central-American specimens the corium is brownish-

ochreous, with the base and apex darker, and the membrane is paler towards the base.

The males have a single, long, very stout, upwardly curved process at the apex of the

terminal genital segment, this process being truncate and slightly emarginate at the

tip; the claspers are long, and strongly curved beyond the middle. The females are

without foliaceous appendages. A single ( 2 ) specimen, labelled “ Mexico,” belonging

to the Vienna Museum (sent to me under the name of A. flavipennis), seems to belong

here; the locality requires confirmation.

6. Apiomerus binotatus, n.sp. (Tab. XIV. figg.11,¢; 11a, 114, last genital

segment, 3.) .

Moderately elongate, rather slender (¢), broader and more robust (@ ), shining, black ; the elytra each with

a large subtriangular ochreous or reddish-ochreous patch on the corium, extending to the outer margin

but not reaching the base or apex, the membrane nigro-fuscous; the anterior coxee and trochanters, a

broad annulus on the posterior tibize before the middle, and usually the base of the anterior and inter-

mediate femora beneath, flavescent; the connexival margins with a row of more or less distinct flavous

spots, the venter sometimes with a submarginal row of similarly-coloured spots; the apical joint of the

antenne ferruginous at the tip ; the body sparsely clothed with erect blackish hairs, and also with a very

short fine decumbent greyish pubescence ; the legs somewhat thickly setose. Antenns with joints 1 and 2

subequal in length, 3 more than twice the length of 2, 3and 4 subequal. Pronotum with the base feebly

sinuate on each side near the hind angles. Elytra extending to far beyond the abdomen in both sexes.

Legs rather slender, the femora slightly swollen before the tip.

g. Terminal genital segment produced at the apex into a short truncated process, which is armed on each

side with a moderately long, upwardly curved, divergent spine, the apex thickly clothed with long hairs ;

the claspers stout, abruptly bent inwards a little beyond the middle; posterior tibia with a short brush

of bristly hairs on the upper edge.

Q. First genital segment truncate at the apex; posterior tibia compressed and sinuous before the apex, and

with a dense brush of short bristly hairs on the upper edge beyond the middle; venter closely pilose.

Length 133-163, breadth 33-54 millim.

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

Found in plenty in Chiriqui. This species resembles A. edatus in colour, except that

it has a flavous annulus on the posterior tibie ; but it is much smaller and less robust,

with the genital structure very different in the male, and the female without foliaceous

appendages. From the similarly-coloured variety of A. mestus, Stal, it may be separated

by the more elongated apical joint of the antenne and the structure of the terminal

genital segment of the male. In one specimen there is a small ochreous spot on each

side of the anterior lobe of the pronotum.

Not uncommon in the Mexican State of Vera Cruz. In this species the corium and

the posterior lobe of the pronotum are usually brownish or piceous, rarely black. The

legs vary in colour from piceous, with the hind tibie (the base excepted) ferruginous

or testaceous, to entirely black. The antenne in some specimens are ferruginous, and

in others almost entirely black. The membrane is uniformly fuscous. The males

have the apex of the last genital segment broadly produced in the centre and armed

with two moderately long, widely divergent, upwardly curved spines; the claspers are

long and somewhat abruptly bent inwards towards the apex.

8. Apiomerus tristis, n. sp. (Tab. XIV. figg. 15,3; 15a, 154, last genital

Robust, black, the posterior lobe of the pronotum piceous in the middle and the anterior femora flavescent

beneath at the base in one specimen ; the membrane fusco-testaceous, mottled with blackish, the two inner

cells dark at the base, the apical portion paler and subhyaline, the nervures at the base, as well as those

on the inner portion of the corium in one specimen, ochreous; the connexival sutures indicated laterally

by an ochreous mark; the antenne and basal joints of the tarsi ferruginous ; the body thickly clothed

with erect blackish sete: and also with short decumbent pallid pubescence; the legs thickly setose.

' Antenne with joint 2 slightly longer than 1, 3 nearly twice as long as 1, 4 a little shorter than 3.

Pronotum with the base feebly sinuate on each side near the hind angles. Elytra extending to far beyond

corresponding sex of that species, and it has the terminal genital segment more trans-

verse and the armature different—the two spines are more widely separated at the base,

the apical margin is angularly dilated or toothed above the points of insertion of the

claspers, and the claspers themselves are shorter and more abruptly bent inwards

beyond the middle.

Sent in plenty from Teapa. Very like A. subpiceus, Stal, and similarly coloured ; but

smaller and less elongate, the membrane in light-coloured specimens usually with

scattered darker spots.

The males have the two spines at the apex of the last genital segment rather short,

upwardly curved, moderately divergent, and widely separated at the base, and the apical

margin of this segment is subangulate on each side opposite the points of insertion of

the claspers; the latter are comparatively short. The genital spines of the male are

shorter, less divergent, and more widely separated at the base than in the same sex of

A, subpiceus.

10, Apiomerus longispinis, n. sp. (Tab. XIV. figg. 18,¢; 18a, 183, last

Moderately robust, shining, black, the corium and posterior lobe of the pronotum sometimes obscure reddish-

brown, the membrane uniformly fuscous or nigro-fuscous, the nervures of the latter usually ochreous at

the base, the connexival sutures indicated laterally by a rufous or ochreous mark, the antenne varying

in colour from black to ferruginous ; the anterior and intermediate femora, trochanters, and coxe some-

times flavous beneath, and the posterior tibis: and tarsi sometimes in great part ferruginous; the body

rather sparsely clothed with erect blackish sete and also with short decumbent pallid pubescence; the

legs somewhat sparsely setose. Antenne with joints 1 and 2 equal in length, 3 nearly twice as long

Fourteen specimens. Very like A. subpiceus, Stal, but usually much darker in

colour, and with the two spines at the apex of the terminal genital segment of the

male much more elongate. These spines are longer than in any of the other species

of the genus known to me; they are stout at the base and taper towards the tip. In

the general shape of the terminal segment the present species agrees with A. subpiceus,

both differing from A. tristis in this respect. The specimens belonging to the Vienna

Museum were sent to me as A. mestus, Stal; the one in the Stockholm Museum was

separated as a distinct species.

Found in plenty at Purula. The type (now before me) was probably from the

Atlantic slope, from Vera Cruz or Tabasco. A rather small species, the males

comparatively narrow, with the elytra extending far beyond the abdomen in both

sexes. The corium usually has an irregular narrow transverse fascia towards the apex,

and one or two of the inner nervures, ochreous, this colour sometimes extending over

the greater portion, leaving the base and apex only dark. The basal margin of the

pronotum is sometimes flavescent. ‘The posterior tibize are in some specimens broadly

ferruginous or testaceous in the middle. The apical joint of the antenne is shorter

than the third, and ferruginous at the tip. The males have two moderately long,

divergent, upwardly-curved spines at the apex of the terminal genital segment; the

claspers are long, strongly curved, and rather stout.

Eight specimens have been seen of this very distinct species, four of which were

obtained by Mr. Smith. It is black, with the membrane in great part clear hyaline,

its base only being infuscate ; the nervures of the corium are either entirely pale or

pale at the apex only. The antenne are ferruginous or fusco-ferruginous, with the

third-and fourth joints subequal in length. The males have two long, widely separated,

divergent, upwardly-curved spines at the apex of the terminal genital segment, the apical

‘The variety nigripes of this very variable Brazilian insect has been recorded by Stal

from ‘‘ Mexico,” on the authority of a male specimen so labelled in the Signoret

collection. This locality is almost certainly incorrect, like that of many other insects

in the same collection. The present species differs from all the Central-American

forms in the rugose posterior lobe of the pronotum. The male has the two spines at

the apex of the terminal genital segment moderately long, divergent, upwardly curved,

and very widely separated, the apical margin of the segment being broadly truncate

between them. The Signoret specimen is figured.

Apparently a common insect in Chiriqui, whence we have obtained a large number

of specimens, chiefly from the savanas of the “tierra caliente.” It is a rather small,

robust species, with stout, closely setose legs, and the intermediate and hind femora

considerably swollen before the apex. The colour is very variable: the pronotum and

corium (except at the tip), and the anterior legs in part, are flavo-testaceous in light-

coloured specimens, the darkest individuals being almost entirely black. A. emargi-

natus differs from all the other Central-American forms in the laterally emarginate base

of the pronotum, as well as in the very peculiar armature of the terminal genital

segment in the male. In this sex the apex of the terminal segment is somewhat

broadly produced in the centre and armed with two very long, upwardly curved, slightly

divergent spines; the claspers are very long and sinuous, angularly dilated and closely

ciliate on the inner side about the middle, and strongly curved beyond, the apical

portion bearing a few very long sete on the outer edge; at the base of these claspers

on the inner side a second short curved pair is visible.

moderately long, divergent, upwardly-curved spine, which is distinctly hooked at the

tip (the armature resembling that of A. subpiceus and its allies, and very different from

that of A. pictipes) ; the claspers are comparatively short, very abruptly bent inwards

a little beyond the middle, and strongly curved at the apex. ‘The females have the

outer apical angles of the first genital segment deflexed and dilated into a subtriangular

concave plate (this being much larger than in the same sex of A. flaviventris and

A, pictipes); the terminal genital segment is strongly transverse. The single ( ? )

Five specimens from Mexico are referred to this species. They differ from the

normal form of A. spissipes in having the pronotum black, with the basal margin

flavous, the connexival margins more distinctly bordered with reddish or flavous, and

the corium dark. This system of coloration, however, seems to be quite constant in

the numerous North-American examples seen, except that the latter have the lateral

and apical margins of the pronotum also reddish. The external genital structure in

both sexes is similar to that of A. spissipes.

Mexico, whence we have received a good series of specimens. The pronotum is rufous,

and usually has one or two transverse black fasciz, the base being broadly flavous; the

apex of the scutellum and the lower part of the propleura are broadly flavous; the

corium is rufous, with the apical margin flavous ; the connexival segments are flavous,

banded with black; the venter (the genital segments excepted) is flavous, with some

spots at the sides and the sutures very narrowly black; the legs are rufous, banded

with black, there being usually a conspicuous rufous ring near the apices of the

intermediate and hind femora; the head, membrane (when closed), and antenne are

black. The males have the apex of the terminal genital segment somewhat broadly

produced in the centre, and armed on each side with a stout, horizontal, laterally

extended, hooked spine; the claspers are long and stout, and strongly curved. The

females have the outer apical angles of the first genital (terminal dorsal) segment

deflexed at the sides, so as to form a triangular plate, and the last segment large and

trapezoidal.

A very variable and abundant species within our limits. Some of the Yucatan

specimens are only separable from A. flaviventris by their slightly smaller size and the

broader black bands across the ventral segments. The genital spines and claspers are

similarly formed in the males of each species; the females, however, have the sides

of the first genital segment more narrowerly deflexed than in the corresponding sex of

A. flaviventris. The large number of specimens received from Yucatan have the

corium (except at the apex), and the pronotum more or less (except at the base), dark,

and the ventral segments broadly banded with pale flavous. Most of the other Mexican

examples, as well as those from Guatemala &c., resemble Herrich-Schaffer’s figure. The

Panama specimens have the corium and the posterior lobe of the pronotum sordid

ochreous. The ventral segments vary greatly in colour, but in the darkest specimens

there are traces at the sides of transverse yellow lines. ‘The six males dissected show

not the slightest variation in the form of the genital spines or claspers.

This genus seems to have its head-quarters in Central America, whence ten species

are now recorded, two only of the four described forms occurring apparently within

our limits, the others inhabiting Brazil and the United States respectively. Some of

them, like the Apiomeri, are very variable in size and colour, and these can only be

satisfactorily separated by the form of the terminal genital segment of the males. In

M. zebra and its allies this segment is produced in the centre at the apex and armed

with a deeply sulcate process, which has the appearance of being formed of two connate,

slender spines. In M. inermis, M. punctipes, and M. nigropictus the dentiform or

spiniform process is simple. The outer and inner genital lobes of the males also vary

in form according to the species.

(H. H. Smith).

This is one of several closely allied forms, the males of which have a long, stout,

sulcate spine at the apex of the last genital segment. The five specimens seen agree

exactly in coloration, the insect differing in this respect from all others of the genus.

‘The posterior lobe of the pronotum, the lateral spines included, is rufous to near the

base, this colour extending on each side down the pleura.

extending to the lateral spines, the longitudinal medium sulcus, and the disc of the anterior lobe, except

four transversely placed spots, black; the scutellum black at the base; the elytra fuscous, or fusco-

testaceous; the abdomen above and beneath, and the basal joint of the rostrum, banded with black; the

Hab. Mexico, Ventanas in Durango (Forrer), Tepic (Schumann).

Two males. Very like WV. zebra, and, like it, with a sulcate spine at the apex of the

last genital segment in the male; the genital lobes, however, in this sex are stout and

clubbed at the tip.

Hab. Mexico, Ventanas in Durango (Forrer).

One male and two females, agreeing precisely in colour. This species is chiefly

distinguishable by the pallid coloration, the clearly biannulate second antennal joint, the

peculiar markings of the head (which are constant), the narrowly annulate legs, and

the very slender short spine at the apex of the last genital segment in the male. It is

perhaps yet another form of WM. zebra.

Hab. Mexico, Dos Arroyos in Guerrero, Atoyac in Vera Cruz, Teapa in Tabasco

(H. H. Smith), San Lorenzo, near Cordova (M. Trujillo).

Twelve specimens, one only of which isa male. Distinguishable by the long slender

spine at the lateral angles of the pronotum, resembling that of 1. punctipes, but less

elongate; the scutellum is also narrowed at the apex, as in that insect. In fresh

An American genus, as restricted by Stal, ranging from Canada to the Argentine

Republic, but chiefly confined to the tropics. Lethierry and Severin enumerate fifty-

two species as belonging to it, but several of the names represent nothing more than

varieties. Eighteen species are here recorded from within our limits, eight of these

being treated as new. Some of them are extremely variable in colour, and one of the

characters used by Stal, viz. the relative length of the basal joint of the antenne,

cannot be depended upon. The males of most of the species have the third antennal

joint thickened, and the last genital segment armed with a process or spine at the apex.

The females in some cases have the hind tibie swollen on the inner side below the

base (Z. janus), and in others the intermediate femora are slightly modified in form

(Z. inconstans and Z. fasciatus). The species of this genus may be easily separated

from the numerous allied forms by the elongate second joint of the rostrum.

Hab. Mexico, Presidio de Mazatlan (Forrer).

A common insect throughout our region, and perhaps not really distinct from

Z. longipes (Linn.), from the Island of St. Thomas. It is very variable in colour,

according to the predominance of the light or dark colour on the head, pronotum, and

elytra; the two forms noticed above are not mentioned by Stal. The antenne are

black, sometimes with one or two pale rings on the basal joint. The legs are black,

with two conspicuous pale rings on each of the femora, which, however, are occasionally

indistinct. The males have the third antennal joint slightly thickened to beyond the

middle, and the terminal genital segment armed with a slender, upwardly curved spine

at the apex. |

The North-American Z. bilobus, Say, a specimen of which from Texas is before me,

has a longer head and pronotum, and the femora almost entirely black *.

_ About 100 examples of Z. rubidus have been examined, including one of Stal’s

specimens from Cuba.

in error.

Four females and one male, all differently coloured. This species is allied to various

S.-American forms, some of which appear to be undescribed, and seems to come near

ZELUS. 255

Z. modestus and Z. prolixus, Stal. It is not quite certain that the male belongs to the

same species; it has both lobes of the pronotum clothed with very short erect blackish

hairs, the anterior angles of the pronotum not prominent, and the sixth ventral segment

clothed with a patch of white tomentum on each side.

4. Zelus pictipes, n. sp. (Tab. XV. fig. 14, 3.)

Elongate, narrow, slender, dull, clothed with fine pallid pubescence and scattered erect hairs ; stramineous,

the head more or less blackish above, with a pale stripe on each side anteriorly and a pale median line

posteriorly ; the anterior lobe of the pronotum nigro-fuscous or black, with six small pale spots (four in a

transverse row behind and two on the disc in front of these), the posterior lobe fusco-testaceous, with the

Z. cervicalis, St&l, but it has the legs annulated with black (as in the species of the

genus Milyas), the legs less elongate, &c. The second joint of the rostrum is elongate.

The head is very little narrowed towards the base, with the post-ocular portion longer

In the Vienna Museum collection there is a female specimen of a Zelus from

Orizaba, as well as a larva of the same species, standing under the name Z. pallens.

This insect is stramineous in colour, and agrees very fairly with Herrich-Schaffer’s

figure. It has a less elongate head than either Z. cervicalis or Z. pictipes, and the

post-ocular portion is much more narrowed behind. The larva is not unlike that of

Z. pictipes, except that the abdomen is without lateral spines and the head is short.

As noted by Stal, there are three well-marked forms of this species: one (a) with

the posterior lobe of the pronotum entirely pale ; one (0) with a transverse black patch

on this part; one (c) like the latter, but with the clavus and corium, the outer margin

of the latter, and sometimes the apex also, excepted, blackish. The black fascia on the

anterior lobe of the pronotum is variable in size, sometimes extending over the greater

part of the disc. The males have the terminal genital segment emarginate at the apex

and armed with a long, slender, upwardly curved spine. The females usually have the

hind tibie slightly thickened on the inner side for some distance before the middle (as

in the same sex of Z. janus), but this is not always the case. The third antennal joint

is slender in both sexes. A specimen from the Volcan de Chiriqui is figured.

others of the same sex from Mexico agreeing perfectly with it. The five males obtained

by Forrer and myself have the lateral angles of the pronotum much less acute, the

ZELUS. 257

pronotum with a large, transverse black patch on the disc of the posterior lobe, and

the clavus and corium, except sometimes the base, apex, and outer margin of the latter

narrowly, black. The antenne are entirely black. The legs are black, with the

intermediate and hind femora in great part, and usually the base of the anterior pair

also, rufous (the two hinder pairs having one or two rings about the middle, and the

apex broadly, black). In the males the head, coxe, and abdomen are bright rufous,

and the ventral segments are banded with black and white; the third antennal joint is

slightly thickened to about the middle, and the terminal genital segment is armed with

a long, slender, upwardly curved spine at the apex, in this sex. A male from Mazatlan

and a female from Milpas are figured.

9. Zelus fasciatus, n. sp. (Tab. XV. fig. 18, 2.)

Q. Elongate, narrow, rather shining, very sparsely pubescent; sanguineous, the pronotum black, with a

broad, transverse, sordid ochreous fascia occupying the anterior half of the posterior lobe; the scutellum,

legs, and antenne black ; the apical two joints of the rostrum piceous; the elytra with the corium

ochreous, the produced apical portion excepted, the clavus black, and the membrane fusco-violaceous ; the

wings smoky; the mesopleura with a small black spot. Head as long as the pronotum, the basal portion

stout and cylindrical ; antenne very long and slender, longer than the body, the basal joint as long as the

head, pronotum, and scutellum united; pronotum rapidly narrowing from the lateral angles forwards,

the latter armed with a slender, acute, outwardly directed spine; the anterior lobe smooth, deeply sulcate

down the middle posteriorly ; the anterior angles transversely tuberculiform, not prominent; the posterior

lobe rugulose; the basal margin narrowly reflexed. Llytra extending to a little beyond the abdomen.

Legs sparsely pilose, very long and slender, all the femora thickened at the base; intermediate femora

slightly tumid for some distance along the middle beneath.

Length 14, breadth 22 millim.

Hab. Panama, Bugaba (Champion).

One example. Allied to Z. nugax and Z. mimus, but very differently coloured and

with a longer head, the latter less narrowed behind. The second joint of the rostrum

is twice as long as the first. The head, abdomen, and under surface are sanguineous ;

the pronotum and elytra are partly black and partly ochreous; the scutellum, legs,

and antenne are black. In the coloration of the head the present species resembles

Z. ruficeps and Z. grassans.

Z. erythrocephalus, Fabr., from Colombia and Guiana, is probably an allied form;

but it is described as black, with the head rufous and the wings cyaneous.

Hab. Muxico, Amula (H. H. Smith).

A very variable insect. The variety «, of which we have received eleven specimens

from Western Mexico, looks, at first sight, distinct. In the typical Z. janus the

anterior and ‘intermediate femora have each a narrow ring at about one-third from the

apex, and the apex of the hind pair broadly, black, the hind tibie usually with a broad

black ring below the base; in some examples the hind femora have only a narrow

black ring before the apex and the intermediate pair are immaculate. The form of

the spine at the lateral angles of the pronotum is variable. The males have a long

curved spine at the apex of the terminal genital segment; the females have the hind

tibie thickened on the inner side for some distance before the middle. The third

antennal joint is slender in both sexes; the first joint varies in length. The types of

Stal’s insects have been seen.

11. Zelus sulcicollis, n. sp. (Tab. XV. fig. 21, 2.)

Q. Elongate, rather robust, slightly shining, thickly pubescent and also clothed with pallid erect hairs;

fusco-testaceous, the post-ocular portion of the head blackish, a median line or spot in front excepted, the

dorsal surface of the abdomen and a transverse fascia on each of the connexival segments blackish, the

corium and clavus reddish in one specimen, the membrane smoky; the intermediate and hind femora

sometimes slightly infuscate at the apex and with indications of a dark ring before the tip; the antenne

rufo-testaceous, with the first and second joints narrowly infuscate at the apex. Head nearly as long as

the pronotum, narrowing posteriorly, the basal portion stout and cylindrical; antenna as long as the

body, the first joint reaching to a little beyond the base of the pronotum. Pronotum sulcate down the

middle from the apex to halfway down the posterior lobe, the latter flattened and moderately dilated at

the sides posteriorly, the hind angles armed with a short triangular tooth ; the anterior lobe smooth, the

posterior lobe feebly rugulose, the basal margin reflexed, the anterior angles transversely tuberculiform.

Elytra extending to a little beyond the apex of the abdomen. Legs elongate, comparatively stout,

pilose; the anterior femora incrassate and as long as the hind femora, the intermediate pair moderately

thickened.

Length 19-21, breadth 44-5 millim.

Hab. Mexico, Tepic (Schumann), Omilteme in Guerrero (H. LH. Smith); GuaTEMALA,

San Gerdnimo (Champion).

Four specimens, all females. Chiefly recognizable by the pilose body, the long

pronotal sulcus, and the incrassate anterior femora. The second joint of the rostrum

is much longer than the first. The tooth at the hind angles of the pronotum is short,

acute, and triangular. Z. swlcicollis is nearest allied to Z. janus, Stal, but differs from

it in the more thickly pilose body, the stouter legs (the anterior femora especially),

and the longer sulcus on the pronotum, the posterior tibiz simple in the female. An

example from San Gerdnimo is figured.

12. Zelus atripes, n. sp. (Tab. XV. fig. 22, 9.)

@. Elongate, broad, shining, finely pubescent and also clothed with pallid erect hairs; testaceous, the

anterior lobe of the pronotum with two small black spots on the disc in front, the connexival segments,

the pleura, and the sides of the ventral segments each with a row of small black spots, the corium with

a black mark at the base of the narrow apical portion, the membrane smoky; the legs (including the

trochanters), rostrum, and antenne black; the head with a short black streak on each side at the base

and another behind the eyes. Head narrowing posteriorly, shorter than the pronotum, the basal portion

stout and cylindrical; antenne with the basal joint about as long as the head and pronotum united.

Pronotum broadly truncate at the base; the posterior lobe dilated at the sides posteriorly, rugulose, the

hind angles armed with a prominent triangular tooth, the basal margin strongly reflexed ; the anterior

lobe smooth, sulcate down the middle, the anterior angles tuberculiform. Elytra extending to a little

beyond the abdomen. Legs elongate, comparatively stout, pilose; the anterior and intermediate femora

moderately thickened, the anterior pair as long as the third pair; the hind tibiee simple.

Length 22, breadth (of the pronotum) 61 millim.

Hab. Panama (Boucard).

One example. The strongly dilated posterior lobe of the pronotum, the black

legs, rostrum, and antenne, and the different coloration distinguish this species from

Z. janus and its allies. The second joint of the rostrum is much longer than the first.

260 HEMIPTERA-HETEROPTERA.

The types of Stal’s species are before me, and, with our long series of specimens for

comparison, it is evident that they are forms of one variable insect. In the typical

Z. exsanguis the posterior lobe of the pronotum is flattened on the disc and considerably

dilated at the sides, and the lateral spines are pale and directed outwards. In Z. luridus

the lateral spines of the pronotum are black, and the pronotum is narrower at the

base. In Z. ambulans the apices of the femora are black, a character of no importance

as the knees are often darker in Z. exsanguis ; and the lateral spines of the pronotum

are usually infuscate or black, these being in some specimens directed forwards

(Z. cognatus, Costa) and in others outwards. The pronotum often has a transverse

row of four or five dots between the two lobes, and the tuberculiform anterior angles,

black ; the lateral spines vary in length. The two basal joints of the antenne are

testaceous or reddish, with the apex infuscate or black; the first joint varies in length.

The males have the third antennal joint thickened to about the middle, and the

terminal genital segment armed at the apex with a stout, tapering, upwardly-curved

spine. The hind tibie are simple in both sexes. The very variable Z. chameleon,

Stal, from Colombia, is an allied form. A female of Z. exsanguis from El Tumbador

is figured.

14. Zelus levicollis, n. sp. (Tab. XV. fig. 24, 2.)

Q. Elongate, narrow, moderately robust, shining, sparsely pubescent, stramineous; the head with the

post-ocular portion black above, a line on each side extending from the eyes to the ocelli, and also one

down the middle, stramineous, the anterior portion mottled with brownish ; the pronotum dilute fuscous,

with the lateral and basal margins, and two transverse rows of small spots on the anterior lobe,

stramineous ; the elytra fuscous, with the costal and median nervures of the corium, as well as the

portion of the latter adjoining the base of the membrane, stramineous, the membrane smoky ; (antenne

broken off). Head elongate, gradually narrowing behind the eyes, the basal portion stout and cylindrical.

Pronotum a little longer than the head; the anterior angles armed with a short stout tooth, the lateral

augles with a very short tooth; the anterior lobe sulcate down the middle, with sinuous lines of

pubescence between the smooth bare spots; the posterior lobe flattened on the disc and with indications

of two anteriorly converging carine in front, apparently smooth, but with a close minute punctuation

showing through from beneath. Scutellum blunt and thickened at the apex. Legs sparsely pilose,

moderately elongate; the anterior femora as long as, but much stouter than, the hind femora; the hind

tibiz simple.

Length 133, breadth of the pronotum 24 millim.

Hab. Mexico, Milpas in Durango 5900 feet (Forrer).

One example. This species is nearest allied to Z. exsanguis, var. luridus, St&l, but

differs from it in having the posterior lobe of the pronotum almost smooth, with the

lateral angles armed with a very short tooth, and the legs less elongate. From

Z. janus (¢), which it resembles in the arrangement of the pubescence on the anterior

lobe of the pronotum, it may be separated by the simple posterior tibie, the much

smaller size, narrower shape, &c.

Nicaragua, Chontales (Janson); Panama, Bugaba, Volcan de Chiriqui, Caldera, David

(Champion).

Sent in abundance from Yucatan. In nearly all the specimens seen the short lateral

spines of the pronotum are black. The femora are usually reddish at the apex,

sometimes with a narrow dark ring before the tip, and in one of the examples from

Bugaba they are faintly annulated with fuscous; the tibiz in some specimens are

also faintly annulated with fuscous. The females are considerably larger than the

males. The latter have the third antennal joint thickened to beyond the middle,

and the terminal genital segment armed at the apex with a long, acute, upwardly

curved spine. A male from David is figured.

Hab. Mexico? (Mus. Holm.** ; coll. Signoret}, in Mus. Vind. Cas. ; Sallé).

This species is very closely allied to Z. nugax, and perhaps not really distinct from

it. The types of Z. mimus and Z. wmbratilis are before me, and I am unable to

separate them. Both appear to have the basal joint of the antenne a little longer

than in Z. nugax; in the type of the female of Z. mimus the posterior lobe of the

pronotum is pale. The antenne and legs are darker, and the latter a little more

slender, than in Z. nugaz. The pronotum has a very short slender spine at the lateral

angles and the base is very feebly margined. ‘The single specimen received by us, a

male, is in a mutilated condition. The sexual characters are similar to those of

Z. NUgax.

17. Zelus nigromaculatus, n. sp. (Tab. XV. fig. 26, 3.)

Very elongate, narrow, slightly shining, sparsely pubescent; flavous, the head with an oblong spot on the

tylus in front, two posteriorly converging lines on the ante-ocular portion, and two oblong marks on each

side of the post-ocular portion (placed one behind the other, and connected in one example), black ;

the pronotum with a transverse fascia on the anterior lobe before the apex and two fascie on the

posterior lobe—one in front and the other before the base,—the two latter connected along each side of

the middle of the disc, and the lateral spines, nigro-fuscous or black ; the scutellum fuscous at the sides

anteriorly ; the clavus and corium fuscous, the nervures of the latter flavous; the membrane and wings

smoky ; the abdomen with the fifth and sixth dorsal segments and a transverse fascia at the base of the

others black; the ventral segments at the sides and the pleura with a series of small black spots; the

rostrum annulated with black at the base; the antenne black; the femora flavous, triannulated with

black, the tarsi and tibie blackish, the latter with two or three pale rings towards the base. Head

about as long as the pronotum, narrowing behind the eyes, the basal portion cylindrical ; antenne very

slender, longer than the body, the basal joint about as long as the head, pronotum, and scutellum

united. Pronotum narrowing from the hind angles forwards, the latter armed with a long, acute, outwardly

directed spine; the anterior lobe smooth, sulcate down the middle; the anterior angles transversely

tuberculiform and rather prominent; the posterior lobe rugulose, without carinez on the disc, the basal

margin narrowly reflexed. Elytra extending considerably beyond the abdomen. Legs very long and

slender, sparsely pilose.

3. Third antennal joint thickened to beyond the middle; terminal genital segment armed at the apex with a

long, slender, upwardly curved, hooked spine.

Length 123-16, breadth 24-23 millim. (¢ @.)

We possess three specimens of this species, agreeing perfectly with the type. The

males have the third antennal joint thickened to near the tip, and the terminal genital

segment produced at the apex into a short, stout, pointed tooth. The second joint of

the rostrum is twice the length of the first. There are two females of Z. tetracanthus

amongst the unnamed specimens in the Stockholm Museum; one of these has the

posterior lobe of the pronotum pale, and the lateral and dorsal spines reduced to blunt

teeth.

with a black line along each side; the pleura partly blackish ; the legs ferrugineo-testaceous, the tibis

more or less infuscate towards the apex. Head short, swollen behind the eyes and also tumid at the base

beneath, armed above with two short obtuse prominences and with the tylus raised along the middle ~

in front, the eyes small; antenne rather short, joint 1 a little longer than 3, 2 short, 4 slightly longer

than 2. Pronotum with the posterior lobe subpentagonal in shape, slightly constricted at the sides,

transversely depressed across the middle, and declivous behind, the produced supra-scutellar portion

longitudinally depressed in the centre and rounded at the tip, the anterior portion moderately inflated,

rounded in front, and almost covering the anterior lobe, the lateral angles rounded ; the anterior angles

lines on the posterior lobe of the pronotum being sometimes connected in front and

behind, so as to enclose two large pale spots on the disc, and sometimes interrupted.

In the darkest specimens the elytra have the base and a broad transverse fascia about

the middle, the latter extending across the base of the membrane and the apex of the

corium, and forwards along the costal and inner margins, but leaving a pale spot on

the membrane, nigro-ceruleous. The femora and the basal joints of the antenne are

very variable in colour. The elytra extend far beyond the abdomen in both sexes.

The third joint of the antenne is not thickened in the males.

A Tropical-American genus including several very closely allied species. The two

now added from Central America seem to be different from any of those described, one

only of which is known to me. They are long and slender insects, with the sixth

abdominal segment armed with a long spine on each side at the apex, the scutellum

rounded behind, the post-scutellum produced into a short tooth, and the head and

pronotum armed with long spines. The species differ sexually in the armature of the

sides of the abdomen, the females having fewer lateral spines than the males.

1. Debilia angustata, n. sp. (Tab. XVI. figg. 8, 8a, 3.)

Elongate, narrow ; stramineous or testaceous, the elytra with an indistinct fascia beyond the middle, the apex

of the corium, the clavus, and the adjoining basal portion of the corium, the nervures excepted, usually

more or less fuscous in mature specimens; the apical portion of the corium in the middle, the knees, and

the dorsal surface of the abdomen, sometimes partly stained with sanguineous. Head shorter than the

pronotum, much narrowed behind, armed above with two long spines, the eyes large and prominent in

the male, smaller in the female; antennz very elongate, joint 1 three times as long as 2, 3 slender in

both sexes. Pronotum armed with two long spines on the disc of the posterior lobe towards the base and

with a long outwardly directed spine at each of the lateral angles, the posterior lobe with two anteriorly

Four females and one male. This species is extremely like D. pilicornis, Stal, the

type (2) of which is before me; but in the female of that insect the connexival

segments 1-5 are each armed with a spine, the eyes are not so prominent, and the long

spines at the apex of the abdomen are curved, instead of straight, as in the Panama

examples. D. macra, Stal, from Brazil, described from a mutilated male specimen, is

another very nearly allied form. In the mature examples of D. angustata the elytra

are more or less distinctly bifasciate beyond the middle.

2. Debilia rufescens, n. sp. (Tab. XVI. figg. 9, 9a, ¢ *.)

Elongate, narrow ; vermilion-red, fading to testaceous or stramineous, the two basal joints of the antenne and

the four hinder femora, except at their apices, flavous, the membrane and wings subhyaline. Head

shorter than the pronotum, armed above with two long spines; the eyes moderately prominent and of the

- same size in the two sexes. Pronotum as in D. angustata. Abdomen with a long straight spine at each

of the outer apical angles of the sixth connexival segment in the male, the spines shorter in the female;

the segments 1, 4, and 5 each with a very short, and 2 and 3 with a long, spine in the male, the segments

1 and 2 only spined in the female.

3. Terminal genital segment armed at the apex with a long, upwardly curved spine, which is truncate and

bent downwards at the tip.

Length 11-13, breadth 2-23 millim. (d 9.)

Hab. Mexico, Teapa in Tabasco (H. H. Smith).

Two males and one female. Very like D. angustata, but vermilion-red in colour, with

the eyes much smaller in the males, and the spines at the apical angles of the first

abdominal segment shorter (obsolete in one specimen) in this sex. The female can

only be separated from that of D. angustata by the rufous coloration and the slightly

shorter spines at the apex of the abdomen. In one of the specimens of D. rufescens

there are traces of two darker fascie on the elytra beyond the middle.

Seven species from Central America are here referred to this American genus, one

of them (R. taurus, Fabr.) being a well-known insect. #. miniata differs from the

others in having the sides and apex of the abdomen spinose, but it seems better placed

here than in Debilia or Rocconota. Some of these insects are superficially very like

Zelus, but they may be easily separated therefrom by the comparatively short second

joint of the rostrum. The third joint of the antenne is, in most of the species, more or

less thickened in the males, this being especially noticeable in BR. fuscipes. |

Not uncommon in Western Mexico, whence we have received many specimens. In

this species the antenne, the anterior margin of the pronotum, the corium, clavus,

rostrum, and legs are constantly black or blackish, and the membrane dark. The

posterior lobe of the pronotum is usually black, with the base sanguineous or testaceous,

the pale colour sometimes extending forwards along the middle and towards the sides,

so as to leave two vitte on the disc. The males have the eyes large and prominent, the

third joint of the antenne much thickened for two-thirds of its length, and the terminal

genital segment armed with a long, upwardly curved spine at the apex. <A male from

pronotum is reduced to two. vitte, and the femora are pale at the base. The outer

margin of the corium is usually pale. The spines on the head and pronotum are very

long. The males have the third joint of the antenne thickened for two-thirds of its

length, and the terminal genital segment armed with a very short tooth at the apex.

This insect is certainly nothing more than a variety of the variable &. taurus, from

which it differs in having the legs pale and the pronotum, at most, faintly streaked

‘with black or fuscous. From Teapa southwards it is much commoner than the dark-

legged R. taurus; the latter does not appear to extend to the S.-American continent,

and it is therefore perhaps more convenient to treat the two forms as distinct. A male

from Teapa is figured.

5. Repipta sanguinea, n.sp. (Tab. XVI. fig. 15, 2.)

2. Moderately elongate, rather broad, sparsely pilose, shining ; sanguineous, fading to testaceous, the pronotal

spines flavous at the tip, the clavus and membrane yellowish, the antenne fuscous, the legs, the

base of the femora and trochanters excepted, much suffused with that colour; the anterior femora and

tibie densely, the intermediate and hind pairs sparsely, pilose. Head smooth, a little shorter than the

pronotum, armed with two very long spines. Pronotum with two very long spines on the dise of the

posterior lobe and a similar spine at each of the lateral angles; the posterior lobe depressed along

the middle and with two short carine in front; the anterior angles transverse, subconical. Elytra

extending considerably beyond the abdomen, the latter unarmed at the sides. Legs elongate.

“Length to the apex of the elytra 15, breadth of the abdomen 4 millim.

Hab. Panama (Boucard).

Three examples. Larger, broader, and more robust than the females of the variable

Z. taurus and Z. flavicans, the legs stouter, the anterior tibiz more densely pilose, the

corium sanguineous, its inner portion and the clavus paler.

6. Repipta gracilis, n.sp. (Tab. XVI. fig. 16, ¢.)

Very elongate, narrow, dull, finely pubescent, and with a few scattered erect hairs; griseo-fuscous or obscure

testaceous (probably reddish or greenish in life), the sides of the pronotum, the nervures of the corium,

and the base of the third antennal joint pale; the legs greenish, fading to stramineous, the apices of the

femora and the tibie usually reddish. Head elongate, much narrowed posteriorly, armed with two short

spines or tubercles, tumid behind the eyes, the latter moderately large; antennz very slender, longer

than the body, the third joint slender in the male. Pronotum longer than the head, armed with two

long, slender spines on the disc of the posterior lobe and with a long spine at each of the lateral angles ;

the posterior lobe rugulose, and with two short carine on the disc in front ; the anterior lobe transversely

wrinkled, with obtuse tuberculiform angles. Scutellum produced into a short, obtuse, horizontal process

behind. Elytra slightly longer than the abdomen, the latter unarmed at the sides ; the elytra with the

discoidal area elongate. Legs hairy, very long and slender, the anterior femora incrassate.

Length 123-14, breadth 2-3 millim. (d 2.)

Hab. Guatemaa, Aceituno and San Gerénimo (Champion); Panama, Bugaba, Volcan

Eleven specimens. Superficially very like Zelus tetracanthus, Stal, but more slender, ©

with the head more narrowed behind, &c. The first joint of the rostrum is much

longer than the second. . In some examples the femora and tibie are greenish towards

the base. The third antennal joint is slender in the males. The females have the

abdomen gradually widened to the apex of the fifth segment. A specimen from

Chiriqui is figured.

REPIPTA. 271

7. Repipta mucosa, n. sp. (Tab. XVI. fig. 17, 3.)

Moderately elongate, narrow, slender, dull, finely pubescent and also with a few scattered erect hairs, the

pleura and the basal margin of the pronotum clothed with an agglutinated whitish tomentum; rufo- or

griseo-fuscous above, paler beneath, the sides of the venter and the dorsal surface of the abdomen sangui-

neous in fresh specimens, the connexival margins pale; the antenne blackish or fuscous, the first joint

usually with a pale ring towards the apex, the third joint flavous at the base; the legs stramineous or

testaceous, the apices of the femora and the bases of the tibie obscurely annulated with fuscous. Head

about as long as the pronotum, tumid behind the eyes, and considerably narrowed posteriorly, armed with

two moderately long acute spines, the eyes a little prominent; antennz very slender, longer than the

body, the third joint in the male thickened at the base. Pronotnm armed with two long slender spines

on the disc of the posterior lobe and with a similar spine at each of the lateral angles; the posterior lobe

flattened along the middle of the disc; the anterior angles tukerculiform, transverse. Scutellum flattened

at the apex. LElytra slightly longer than the abdomen, the discoidal area short. Abdomen unarmed at

the sides. Legs pilose, slender, the anterior femora thickened towards the base, the hind femora (when

extended backwards) reaching very little beyond the fourth abdominal segment.

Length 8-10, breadth 13-2 millim. (¢ 9.)

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

A common insect in Chiriqui. Allied to &. gracilis, but much smaller and less

elongate, the legs relatively much shorter, the posterior lobe of the pronotum smoother,

the first joint of the rostrum not much longer than the second, the discoidal area of the

elytra short. £. mucosa is also very like Zelus nugawx and other small species of that

genus, but it is easily separable therefrom by the short second joint of the rostrum.

8. Repipta miniata, n.sp. (Tab. XVI. figg. 18, 18a, ¢.)

Elongate, rather slender, sparsely pilose; vermilion-red, fading to stramineous, the membrane yellowish-

hyaline, the pronotal spines and carine yellowish; the antennz fuscous, the basal joint obscurely

annulated with stramineous, the two outer joints sometimes ferruginous ; the legs stained or irregularly

annulated with fuscous, the anterior femora with a fuscous line along their upper edge. Head compara-

tively short, armed with two long spines, the eyes prominent and rather large in both sexes; antenne

very long and slender, joints 1 and 3 about equal in length, 2 short, 4 longer than 2, 3 slightly thickened

in the male. Pronotum about one-half longer than the head, armed with two very long spines on the disc

of the posterior lobe and with a very long spine at each of the lateral angles; the posterior lobe rugulose,

and with two anteriorly converging carine extending forwards from the base of the spines, the space

between the carine flattened ; the anterior lobe deeply sulcate down the middle, and with obtuse tuber-

culiform angles. Scutellum produced at the apex into a rather long horizontal dentiform process.

Elytra considerably longer than the abdomen; the membrane with the basal area about twice as long

as the outer one, the latter strongly transverse. Connexival segments 1-5 each armed with a short

spine at their outer apical angles, the spines becoming very short posteriorly ; the sixth segment with a

rather long curved spine in the male and a short one in the female. Legs very elongate, slender, the

anterior femora incrassate. Terminal genital segment of the male armed with a short spine at the apex.

Length to the apex of the elytra 143-164, breadth 23-33 milim. (d 2.)

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

Two males and one female. Differs from Repipta, as defined by Stal, in the spinose

sides of the abdomen. It closely approaches the genus Dedilia, but has a differently

formed post-scutellum, longer elytra, and more obtuse spines at the outer apical angles

of the sixth connexival segment. ‘his insect bears a certain superficial resemblance

to some of the similarly coloured species of Saica.

It is doubtful if this Tropical-American genus can be retained as distinct from

Repipta, Stal. The species here referred to Rocconota have the anterior femora more

or less incrassate, the third antennal joint slender in both sexes *, the abdomen with

one or more of the basal segments armed with a spine at the outer apical angles

fuscous, the four hinder femora obscurely annulated with darker colour near the apex (perhaps due to

discoloration), the long spines on the posterior lobe of the pronotum black at the base in front and flavous

at the tip. Head elongate, smooth, armed with two long spines; antennez long and slender. Pronotuma

little longer than the head, armed with two blunt divergent spines on the disc of the anterior lobe, and

with two long acute spines on the posterior lobe and a similar spine at each of the lateral angles; the

posterior lobe rugulose and with indications of two faint anteriorly converging carine on the disc extending

from the spines forwards; the anterior lobe smooth and sulcate, with the angles subconically tuberculate.

Scutellum produced at the apex into a short horizontal dentiform process. Elytra slightly longer than the

abdomen, the discoidal cell moderately long, the basal area of the membrane longer than the outer one.

2. Rocconota leviceps, n.sp. (Tab. XVI. fig. 20, 2.)

¢. Elongate, rather robust, shining, sparsely pilose ; testaceous, the lateral portions of the head slightly

infuscate, the pronotum broadly nigro-fuscous at the sides, the tips of the spines flavous, the corium fuscous

to near the tip, the inner basal portion excepted, the connexivum with a series of black spots; the antenne

with joints ] and 2 flavo-testaceous, annulated with fuscous, 3 and 4 ferruginous, 3 flavous at the base ;

the femora each with two faint annuli towards the apex, and the tibie with a single annulus near the

base, dilute fuscous. Head a little shorter than the pronotum, smooth and shining, armed with two very

long spines. Pronotum with two long spines on the disc of the posterior lobe and a long outwardly-

directed spine at each of the lateral angles; the anterior lobe transversely wrinkled, smooth, with the

tuberculiform angles obtuse and prominent; the posterior lobe rugulose. Scutellum with an upwardly-

curved spine at the apex. Abdomen wider than, and nearly reaching the apex of, the elytra, the first

two connexival segments each armed with a rather long spine at the outer apical angles. Venter smooth

and shining. .

Length 14; breadth of the pronotum 33, of the abdomen 4? millim.

We have received six examples of this species, and three others have been seen,

inclnding one of the types. There is no trace of a tubercle or plica on the mesopleura

in front, the insect therefore cannot belong to Heza. RB. annulicornis is closely allied

to R. tuberculigera, but differs from it in having the first connexival segment armed

with a spine at the outer apical angles; it is also more pubescent, the scutellum is less

produced at the apex, and the pronotal spines are flavous at the tip. The basal joints

of the antenne are more or less distinctly annulated with brownish or fuscous, as are

also the femora towards the apex and the tibiz at the base. ‘The under surface is very

small bare spots. |

The males have an upwardly curved spine at the apex of the last genital segment,

and the third antennal joint slender. The single specimen obtained at Paso Antonio,

from which our figure is taken, has the legs and antenne much more distinctly annu-

lated than in any of the Mexican examples before me.

4, Rocconota hystricula, n. sp. (Tab. XVI. fig. 22, ¢.)

Elongate, pilose, and also clothed with a fine scattered pubescence, shining testaceous, the head and the anterior

lobe of the pronotum dilute fuscous, the posterior lobe nigro-fuscous, with the base broadly, and the tips

of the spines, like those of the head, flavo-testaceous; the corium sometimes fuscous between the nervures,

the membrane with the longitudinal nervure more or less infuscate, the abdomen above flavo-testaceous,

broadly, transversely fasciated with fuscous, the venter broadly infuscate down the sides, the dark portions

enclosing a submarginal series of pale spots; the antenne with joints 1 and 2 flavous, annulated with

fuscous, 3 and 4 ferruginous, 3 flavous at the base; the legs flavous, broadly annulated with fuscous.,

Head nearly as long as the pronotum, smooth, armed with two leng spines, the eyes prominent ; antenne

very elongate, slender, similarly formed in both sexes. Pronotum armed with two long spines on the dise

of the posterior lobe, and with a long spine at each of the lateral angles; the anterior lobe transversely

wrinkled, smooth, with the angles obtuse and tuberculiform; the posterior lobe rugulose. Scutellum

produced into a short obtuse prominence at the apex. LElytra considerably longer than the abdomen.

First connexival segment armed with a spine at the outer apical angles, the other segments subangularly

dilated at the sides behind. Anterior femora feebly incrassate.

posterior lobe of the pronotum are occasionally obsolete ; but in others they are very

elongate. ‘The abdominal segments are unarmed at the sides in both sexes. The apex

set with widely scattered raised white points (similar to those visible in Heza similis) ;

the abdominal segments 1-4 in both sexes are each armed with a spine at their outer

apical angle, that on the fourth segment being much shorter than the others. The

spines on the head and posterior lobe of the pronotum are long, and on the anterior

lobe of the latter there are two prominent conical tubercles. ‘The males have the third

joint of the antenne slender, and the terminal genital segment armed with a short

spine in the centre at the apex. A specimen from Bugaba is figured.

SOSIUS, n. gen.

Head rather more than half the length of the pronotum, tumid behind the eyes, narrowing posteriorly into a

short neck, armed above in front with two long, anteriorly curved, acute spines, and with a short spine on

each of the gene, the eyes moderately large in both sexes ; rostrum with joint 1 as long as 2 and 3 united ;

antenne long and slender, joint 3 not thickened in the male. Pronotum as long as broad, subpentagonal,

deeply emarginate behind, the posterior lobe with two long acute spines on the disc and a similar spine

at each of the lateral angles. Scutellum with an obtuse prominence at the apex. Elytra about reaching

the apex of the abdomen ; the outer area of the membrane slightly shorter than the inner. Abdomen

elongate, narrow at the base, gradually widening to the apex of the fourth segment, the fifth and sixth

segments abruptly and conjointly foliaceous in both sexes, the fifth acutely produced at the outer apical

angles, the sixth rapidly narrowing behind, with the apex rounded or subtruncate. Legs moderately

long, the anterior pair stout, the two other pairs slender; anterior femora greatly incrassate and about

as long as the hind femora, the latter not reaching beyond the apex of the fourth ventral segment.

Mesopleura neither plicate nor tuberculate. Claws appendiculate.

This genus is readily recognizable by the conjointly and abruptly dilated fifth and

sixth connexival segments, the margins of these segments (as in certain species of

Phymata) forming an acute-angled foliaceous plate. The legs, compared with the

abdomen, are rather short, the anterior pair stout, the two other pairs slender. Sosius

approaches Locconota, Stal.

1. Sosius foliaceus, n. sp. (Tab. XVI. figg. 25, 25a, 3.)

Obscure ferruginous, sparsely clothed with greyish pubescence ; the antenne with joint 1 fuscous, biannulated

with fiavous or ferruginous, the other joints ferruginous ; the anterior legs fuscous or fusco-ferruginous,

the femora indistinctly annulated with ferruginous, the tarsi flavescent ; the intermediate and hind legs,

the second and third joints of the rostrum, and in one specimen the first three ventral segments, flavous,

the femora fuscous at the apex and sometimes with a fuscous ring beyond the middle. Pronotum sulcate

fifth connexival segment are very acutely produced in the Atoyac specimens, forming a

sharp spine. A male from Atoyac is figured.

This genus is based upon a single species, L. sahlbergi, Stal, from Brazil. The

second species now added, also known from a single female specimen only, is very like

it, agreeing perfectly in the structure of the head, pronotum, &c.; but has the abdomen

longer and less dilated posteriorly, with the sixth connexival segment, as well as 1-5,

armed with a long spine at the outer apical angles. Both insects have a small discoidal

area on the corium adjoining the base of the membrane, but in ZL. ericius the two

areas of the membrane are unequal in size. The type of L. sahlbergi has been kindly

communicated by Dr. Aurivillius.

2. Elongate, sparsely pubescent and also clothed with long, fine, scattered hairs; above fuscous, the head in

front and at the base, the pronotum with a space along the middle of the disc, the tips of the spines, and

the basal angles, and the apex of the scutellum, stramineous ; the elytra with the nervures pale, the

membrane subhyaline, with a spot opposite the apex of the corium and another on the median nervure

fuscous ; the abdomen stramineous, the connexival segments banded or spotted with nigro-fuscous ; beneath

stramineous, the apical half of the venter in great part nigro-fuscous; the antenns stramineous, with the

two basal joints annulated with fuscous ; the legs stramineous, annulated with fuscous and black. Head

much shorter than the pronotum, strongly narrowed behind, armed above with two long erect spines before

the eyes, which are large and prominent; antenne longer than the body, slender, joint 1 more than twice

as long as 2, 2 shorter than 4. Pronotum hexagonal, the posterior lobe much widened laterally towards

the base, with two anteriorly converging carine on the disc connecting the two lobes; the posterior lobe

armed with two long, backwardly directed spines on the disc and a long, outwardly directed spine at each -

of the lateral angles. Scutellum with an obtuse prominence at the apex. Elytra extending far beyond

the abdomen, the inner area of the membrane a little longer than the outer one. Abdomen widening to

the apex of the fifth segment, and narrowing thence to the apex, the apex broadly subtruncate, the outer

apical angles of the connexival segments 1-6 each armed with a long spine. Legs long and hairy; the

femora somewhat thickly pilose at the apex, the anterior pair strongly incrassate, the latter, as well as

the anterior tibie, closely ciliate within.

Length (to apex of the elytra) 133, breadth (of the fifth segment of the abdomen) 34 millim.

The two Central-American species referred to this genus differ from the typical

forms, C. ‘columbica and C. capitata, Stal, from Colombia, in having the abdomen

unarmed at the sides and the spines on the head reduced to small tubercles. All of

them have long spines on the posterior lobe of the pronotum, a comparatively short,

broad abdomen, and long elytra. C. seadens and C. spinosa (Fabr.), from Guiana,

evidently do not belong here.

spot on the anterior lobe, the scutellum in the middle, and the clavus, black; the fourth and fifth

connexival segments each with a broad transverse fascia above and beneath, and the ventral segments 1-5

with a narrower fascia, black ; the membrane yellowish-hyaline, with the longitudinal median nervure slightly

the usual spines before the eyes reduced to two small tubercles, the eyes moderately prominent; antennee

long and slender, joint 1 more than three times the length of 2. Pronotum armed with two long spines

on the disc of the posterior lobe and with a long spine at each of the lateral angles ; the anterior angles

tuberculate, but not very prominent ; the posterior lobe with very fine punctures showing through from

beneath. Elytra nearly twice as long as the abdomen.

Two specimens. Very like C. colwmbica, Stal, from Colombia, the type of which is

before me, but differing from it (and from C. capitata, Stal, also, which is probably a

colour-variety of the same species) in the more elongate head, with the spines reduced

to small tubercles, the less prominent anterior angles of the pronotum, and the unarmed

sides of the abdomen. In C. columbica, moreover, each of the connexival segments is

banded with black, and the main nervures of the membrane are nigro-fuscous.

We have not received a specimen of this species, our figure of which is taken from

one of the types. It differs from C. plagiaticollis in having the lateral angles of the

pronotum armed with a stout outwardly projecting tooth, the head longer, and the legs

much stouter, the femora especially. ‘The expanded postero-lateral margins of the

pronotum are continued beneath the lateral spines, so that the latter appear to be

emarginate behind.

5. Castolus rufomarginatus, n. sp. (Tab. XVII. fig. 7, 2.)

Q. Elongate, rather robust, somewhat shining ; nigro-piceous or black, the head, a streak on each side behind

excepted, and some spots on the anterior lobe of the pronotum, obscurely rufescent ; the posterior lobe of

the pronotum at the sides and base, the scutellum in great part, the pleural margins, the connexivum,

and the dorsal segments of the abdomen, except along the middle, sanguineous, the membrane smoky ;

clothed above and beneath with very short grey decumbent pubescence and with scattered intermixed

erect hairs, the legs thickly pilose. Head gradually narrowing behind, armed with a short conical

tubercle on each side before the eyes, the latter large; antenne slender, joint 1 slightly longer than, and 2

not half the length of, 3. Pronotum with the posterior lobe angularly dilated at the sides, rather broadly

margined at the base laterally, the base truncate in the middle, the disc with two short anteriorly

converging carine in front; the anterior lobe sulcate down the centre, the anterior angles obtuse

and tuberculiform. Elytra extending beyond the abdomen. Legs rather stout, the anterior femora

incrassate.

Two specimens, the one from Vera Paz being immature and in a bad state of

preservation. Allied to C. suéinermis, Stal, but very differently coloured, and with the

lateral angles of the pronotum unemarginate behind. It is very like Repipta fuscipes

in general appearance. In the Mexican example, which we figure, the venter is thickly

cinereo-pubescent, with a series of transverse bare spaces along the sides.

We possess a long series of this species, varying in the colour of the pronotum and

also to a certain extent in that of the femora. In many of the specimens the pronotum

is entirely rufo-testaceous (draconiformis, Burm.) ; but in others, both from Guatemala.

and Chiriqui, it is partly or entirely black, the basal margin or a subtriangular patch

on the disc behind being pale in some examples (pompilodes, Burm.). The intermediate

and hind femora are broadly, and the anterior pair sometimes narrowly, black at. the

base ; the hind pair have the apex broadly, and rarely a median ring, fuscous or black,

and the intermediate pair are often infuscate at the apex. The males have the third

antennal joint thickened at the base. H. braconiformis is very like Graptocleptes

cingulatus, Stal, from Colombia; but in the latter the head is armed with two spines,

the legs are shorter, the head is clothed with shorter hairs, the scutellum is produced

into an acute tooth behind, &c. It resembles various large Braconide occurring in

the same districts. We are indebted to Dr. Aurivillius for the loan of specimens of

H. braconiformis and G. cingulatus.

We figure a pair from Bugaba, showing the variation m colour amongst specimens

from the same locality.

GRAPTOCLEPTES.

our region. The species now added is extremely variable in colour. The males may

be known by their large and prominent eyes and the thickened third antennal joint.

of the disc, the black markings in some specimens extending to the sides and apex (leaving only a trian-

gular patch on the disc behind yellow) and in others entirely obsolete; the elytra with the base of the

clavus, the base or outer part of the corium, and a large patch of variable extent at the apex of the

membrane, and sometimes a transverse median fascia, fuscous or black, the clavus and corium in some

specimens almost entirely infuscate (and the membrane also) and in others entirely ochreous ; the wings

flavo-hyaline, the apex only sometimes narrowly infuscate; the antenne black ; the legs black or fuscous,

the anterior and intermediate femora to a greater or less extent flavescent at the base, the intermediate

and posterior pairs with a flavescent ring before the tip, the intermediate femora sometimes flavescent to

near the apex. Head nearly as long as the pronotum, with a few widely scattered hairs only above and

beneath, armed with two short spines or conical tubercles above; the eyes large and prominent in the

male, smaller in the female; antenne with joint 3 greatly thickened in its basal half in the male.

Pronotum with rather prominent, laterally projecting anterior angles, both lobes depressed down the

middle, the posterior lobe with indications of two converging carine on the dise anteriorly, the lateral

angles obtuse and somewhat tumid. Scutellum produced into a short tooth behind. Elytra extending

far beyond the abdomen. Legs rather slender. Rostrum with joint 1 almost as long as the two others

united.

Length to apex of the elytra 13-133 millim. (¢ 9.)

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

This very variable species is not uncommon in Chiriqui, and amongst the twenty-

seven examples examined four only have the dark median fascia on the elytra: three

have the corium and clavus pale, except that in one of them (¢) the dark median

fascia is present and crosses the corium. G. varians is very like the South-American

G. fasciatus (Fabr.) (=gracilis, Burm.), a female specimen of which has been lent me

by Dr. Aurivillius; but it differs from that species in having the head a little longer

(both before and behind the eyes) and almost glabrous beneath, the antennze more

slender, the under surface and pleura almost entirely pale, the wings not fasciate, &c.

The colour of the legs and upper surface is very variable: the elytra are sometimes

almost entirely infuscate, but in the pale examples the dark patch is always present

at the apex of the membrane; the anterior and intermediate femora are sometimes

flavescent, with the apex only dark, the hind pair, however, always have the base and

a ring before the apex flavescent. The fasciate form resembles G. cingulatus, Stal

(the type of which is before me); but it is much smaller and has more slender legs, the

head is almost glabrous and not at all convex beneath (convex and densely pilose

beneath in G. cingulatus), the wings are not fasciate, the spines on the head are

shorter, &c.

From G. flavidatus, Stél (the type of which has also been seen), it may be separated

by the dark apex of the membrane. We figure four of the extreme forms.

Museum have been seen, including one of the (2) types. It varies a good deal in size,

and some examples have a large sanguineous patch on the disc of the posterior lobe of

the pronotum. The femora usually have each a narrow pale median annulus, but this

is sometimes present on the hind pair only. The males (unknown to Stal) have large

and prominent eyes, the third joint of the antenne thickened to beyond the middle,

and the terminal genital segment somewhat broadly produced in the centre at the

apex.

incrassate, and the head is armed with two moderately long spines, the post-ocular

portion being thickly pilose above and beneath. It is shining black, with the basal

half of the venter bright sanguineous ; the femora have each a narrow pale annulus at

the middle.

The two described species of this genus are from the Southern United States and

the Argentine Republic respectively ; the first mentioned extends southwards to Mexico

and Guatemala. A third is now added from Panama. Atrachelus is very imperfectly

characterized by Amyot and Serville, and their figure is a bad one. The genus is easily

separable from Acholla and Sinea by the unarmed anterior femora. Phorobura, Stal,

including three species from Tropical South America, seems only to differ from

Atrachelus in having the post-ocular portion of the head relatively longer.

Not uncommon in Mexico, whence about twenty specimens have been seen. In

both sexes of this species the connexival segments 1-5 are angularly dilated or spinose

at their outer apical angles, there being considerable variation in this respect. The

third antennal joint of the males is also much more thickened in some examples than

in others. The abdomen is subparallel in the males, rounded at the sides in the females.

A common insect in the Southern and Eastern United States, extending southwards

along the Atlantic slope to Guatemala. According to Prof. Uhler °, it lives upon small

pine-trees and preys upon caterpillars and other insects. Of the twelve specimens

before me from Mexico and Guatemala, one only is of the male sex. J. cristatus

differs from the 8.-American and Antillean A. carinatus, Forst. (=serratus, Fabr., and

santhopus, Walk.), in having fewer tubercles on the crest of the pronotum (12-14 in

A. carinatus, 8-10 in A. cristatus), and the margins not distinctly dilated behind the

postero-lateral angles. The margins of the abdomen are sinuate in both sexes. Walker!2

states that the legs are wholly black in P. patulus, but in his type the posterior tibize

are obscure ferruginous.

dilated behind the projecting postero-lateral angles and the spines at the base shorter ;

the margins of the abdomen, too, are rounded and almost entire (instead of being

distinctly sinuate, as in A. cristatus). The front of the head, the rostrum, antenne,

and tibiee, and the apices of the anterior femora, are more or less ferruginous, and the

intermediate and hind femora are sometimes obscurely ferruginous towards the base.

The pronotal crest is furnished with 9-11 tubercles. About sixty specimens have been

examined.

A well-marked American genus easily distinguishable by the strongly raptorial front

legs, the anterior femora and tibie being each armed with a double series of long

spines, and the anterior femora having also a long spine near the apex above. Its

head-quarters are within our limits, whence seven species are now recorded. They are

extremely closely allied and difficult to separate, unless specimens of both sexes are

available for examination, several of them having a very differently shaped abdomen

in the males. Of the six species described by Stal, four were based upon females only.

Fortunately, we are now enabled to make good this deficiency and to characterize both

sexes of all the Central-American forms. ‘The three or four North-American species

stand greatly in need of revision. It may be noted that in most of the Sinee the

form of the lateral angles of the pronotum is variable and the spines on the head

vary in length.

The Central-American forms may be thus separated :-—

Prof. Uhler has been kind enough to send me males and females of S. diadema (Fabr.)

and S. undulata: the males I am unable to separate specifically; but the females

differ in the amount of sinuation of the sides of the abdomen, S. diadema having the

fourth and fifth segments strongly and subangularly dilated in this sex and S. undulata

having the same segments almost arcuately dilated. The common Central-American

representative of this group agrees with the latter in this respect, and I therefore

adopt the name of S. undulata for it. Stal! noticed certain differences between the

Mexican and North-American examples. The specimens before me (including a long

series from Yucatan) vary greatly in size and colour, most of them being testaceous,

and the pair of 8. undulata from California are larger than any of those from within

our limits. The present species is easily recognizable from all the other Central-

American members of the genus, S. coronata excepted, by the distinctly bigibbous

posterior lobe of the pronotum. About 100 examples have been examined, nine only

of which belong to the variety, the latter being connected with the others by inter-

mediate forms. The Mexican specimen in the Vienna Museum, from the Signoret

collection, is labelled S. indegra, Stal. A female from Yucatan is figured.

We possess one male and five females of this species. The abdomen of the male is

narrow and subparallel to the apex of the fourth segment; the fifth and sixth segments

are conjointly and angularly dilated, the sixth being produced posteriorly and truncate

at the apex; the connexival margins are minutely denticulate; and the terminal

genital segment has a broad, upwardly curved, spoon-shaped process at the tip. The

abdomen of the female is broadly dilated beyond the middle, with the fifth segment

SINEA, 293

subparallel. ‘The anterior tibiz are armed on each side beneath with three very long

spines, alternating with three short ones. SS. coronata is more elongate than any of

the other species of the genus known to me: it agrees with S. diadema (Fabr.) and

S. undulata, Uhler, in having two distinct gibbosities on the posterior lobe of the

pronotum, but differs from both in the shape of the abdomen. The head has a row

of three spines on each side before the eyes, the posterior one being very elongate.

Stal’s type has been examined. A male from San Gerénimo and a female from

Valladolid are figured.

femora in part, testaceous or fusco-testaceous, the basal joint of the antenne with a flavous ring. Head

as long as the pronotum, armed on each side before the eyes with a row of three acute spines, the

posterior one very elongate and the anterior one short, and with several spines near the ocelli and some

scattered granules or conical tubercles on the neck. Pronotum with the two lobes about equal in length ;

the anterior lobe armed with numerous short, pointed, piligerous tubercles; the posterior lobe trans-

versely convex, coarsely rugose, the lateral angles produced into an acute outwardly directed spine, the

basal margin with a row of short piligerous spines. Abdomen( ¢) narrow, slightly rounded at the sides,

gradually narrowing from the apex of the fourth segment, and with the apex of the sixth produced into

a short, broad, caudiform process, which is emarginate in the centre at the tip and has the outer apical

angles rounded; ( @ ) broad, rapidly widening to the apex of the fourth segment and narrowing thence to

the tip; the connexival margins finely denticulate in both sexes. Anterior femora with a very long spine

near the apex above and with a row of four spines on each side beneath ; anterior tibie with three long

spines on each side within.

Length 8-103 ; breadth, ¢ 14-24, 9 33-32 millim. (¢ 9.)

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

_ Five males and six females are referred to this species. The males are very like

those of S. raptoria (=denticulosa, Stal), but they may be readily distinguished by

the subcaudate apex of the abdomen; the females can only be separated from the

corresponding sex of that species by the more acute tubercles on the anterior lobe of

the pronotum. In one of the males the outer apical angles of the fourth connexival

segment are somewhat prominent.

_ The types (2) of S. raptoria and S. denticulosa are before me, and I am unable to

separate them. The male of S. raptoria was unknown to Stal: it is very like that of

294 HEMIPTERA-HETEROPTERA.

S. caudata, but the apex of the abdomen is subtruncate and not produced. In this sex the

abdomen is long and narrow, subparallel to the apex of the fifth segment and narrowing

thence to the apex, which is subtruncate. The females have the abdomen widened to the

apex of the fourth segment and narrowed thence to the apex, the outer apical angles of

the fourth segment being more or less prominent. The connexival margins are minutely

denticulate in both sexes. The third spine of the double series on the ante-ocular

portion of the head is very elongate. The females are only separable from those of —

S. defecta by this last-mentioned character; but the males of these two species are

very different. The anterior lobe of the pronotum is set with very short subconical

tubercles. In our numerous Mexican and Guatemalan specimens the spiniform lateral

angles of the pronotum are directed a little backwards, while in the long series of both

sexes from Chiriqui they are directed outwards, but this difference is not constant. A

male from Teapa is figured. |

Stal appears to have confused two species under this name, as he gives! “ the

posterior lobe of the pronotum as unarmed or with scattered spinules on the disc”:

the specimen (¢) in the Signoret collection named by him belongs to S. undulata.

The name integra is here retained for the insect with distinct spines on the disc of the

posterior lobe of the pronotum. It is very like S. undulata and S. diadema, and has

the head and anterior lobe of the pronotum similarly spinose ; but the posterior lobe

of the latter is not bigibbous on the disc, and the abdomen of the female is gradually

widened to the apex of the fourth segment and narrowed thence to the apex (instead

of being undulate at the sides as in S. undulata). ‘The abdomen is rounded at the

sides in both sexes, and, as usual, narrower in the male than in the female. Seven

specimens only have been seen, including one of Stal’s types (¢) belonging to the

Stockholm Museum. A Yucatan example is figured.

S. sanguisuga agrees with S. defecta in having the abdomen somewhat similarly

SINEA. 295

shaped in both sexes, but considerably narrower in the males than in the females: it is

widened to the apex of the fourth segment and narrowed thence to the tip, the outer

apical angles of the fourth segment, and those of the fifth also, in the males, being

sometimes prominent or subdentiform. ‘The connexival margins are crenulate or finely

denticulate. JI am unable to find any certain character by which to distinguish some

of the females before me from those ot S. raptoria. Stal’s type ( 2 ) has been seen.

A male from Cerro Zunil is figured.

(Janson) ; Costa Rica, Irazu (Rogers); Panama, Volean de Chiriqui, Tolé (Champion).

A common Central-American species, extending southwards to the State of Panama.

Stal’s first description appears to have been made from a single imperfect female

example, with the long spine near the apex of the upperside of the anterior femora

broken off. In some specimens (as in the type) the second and third spines of the

series on each side of the ante-ocular portion of the head are reduced to small rounded

tubercles, but in others they are as long as the anterior one. ‘The anterior lobe of

the pronotum is set with scattered rounded or short subconical tubercles; the posterior

lobe is very coarsely rugose, without distinct gibbosities on the disc; the lateral angles

are moderately acute. ‘The abdomen is very similarly shaped in both sexes, somewhat

rounded at the sides, but narrower in the male than in the female; it is gradually

widened to the apex of the fourth segment and narrowed thence to the apex, the outer

apical angles of the fourth segment being more or less prominent in the male; the

connexival margins are feebly serrulate.

S. defecta is very like an insect from the Southern United States sent to me by

Prof. Uhler as S. spinipes (Herr.-Schaff.), a species not identified by Stal; but in the

latter the lateral angles of the pronotum are more acute and the spines on the head

are longer*; S. rileyi, Mont., from California, must also be a nearly allied form. The

comparatively short third spine or tubercle of the ante-ocular series will separate the.

present species from many of its allies.

Ninety specimens have been examined. An example from Cuernavaca is figured.

* These specimens, from Maryland and Florida, agree very well with Herrich-Schiiffer’s figure, though his

species is stated to be from “ South America.”

296 HEMIPTERA-HETEROPTERA.

Dr. Aurivillius has recently sent me for examination a very interesting Reduviid of

the subfamily Acanthaspidine from Costa Rica, too late for insertion in its proper

place, after the genus Lamus, antea, p. 211. We therefore place it here, at the end

of the Reduviide.

VOLESUS, n. gen.

Head short, small, with the antenniferous tubercles obliquely projecting in front, cylindrical, and unarmed ;

eyes rather small, transverse if viewed from the side; ocelli placed a little behind the usual transverse

groove; antenne inserted at the apex of the antenniferous tubercles, joint 1 rather stout, much longer

than the head, 2 more slender and a little longer than 1, 3 and 4 very slender, 3 not half the length of 2

and twice as long as 4. Pronotum trapezoidal, the anterior lobe very short. Scutellum produced into a

stout cylindrical process at the tip. Membrane with the outer area a little longer than the inner one.

Abdomen broad, with wide connexival margins. Rostrum slender, joints 2 and 3 equal in length, received

into a broad deep groove in the prosternum. Prosternum narrowly produced and declivous between the

anterior coxe, and armed with two blunt, compressed, dentiform processes in front, these extending

forwards from the ridge bordering the rostral groove on each side posteriorly. Legs comparatively

slender, each of the femora slightly compressed before the apex beneath; tarsi 3-jointed, claws simple.

Body broad and robust.

This genus is almost intermediate between Spheridops and Veseris: the antenniferous

processes are unarmed, the second and third joints of the rostrum are subequal in

length, and the first antennal joint is longer than the head, as in Veseris; but the

prosternum is not obtusely rounded posteriorly as in that genus (following Stal’s

description), but narrowly produced as in Sphwridops. The head is very small.

1. Volesus nigripennis, n. sp. (Tab. XVIII. fig. 14, 2.)

2. Opaque above, slightly shining beneath, black ; the pronotum sanguineous, with two anteriorly converging

vittee on the disc of the posterior lobe and two faint vitte towards the sides, all connected in front, and the

median portion of the anterior lobe, black ; the scutellum bordered with sanguineous behind, the apical

process ochraceous ; the abdomen transversely banded with sanguineous, the sixth segment in great part

red; the prosternum with a red streak on each side in front of the anterior coxe ; the legs blackish, the

tarsi fusco-testaceous ; the body beneath, the antenne, and legs shortly pilose, the antennal joints 2-4

with longer, projecting hairs. Head, pronotum, and scutellum coarsely rugose ; the pronotum narrowly

sulcate down the middle of the posterior lobe, the lateral angles produced into a blunt tooth, the anterior

lobe nodose at the sides behind, the anterior angles obtuse. The under surface densely, transversely

rugulose, the venter smoother along the middle.

Length 19, breadth 82 millim.

Hab. Costa Rica (BSovallius, in Mus. Holm.).

NoreE.—In my enumeration of the species of Apiomerus, antea, pp. 230-243,

omitted. It is probably a variety of A. crassipes (Fabr.) or of A. spissipes (Say):

the description is almost useless for the purposes of identification, colour only being

noticed.

APHELONOTUS.

Aphelonotus, Uhler, P. Z. S. 1894, p. 208.

This peculiar monotypic genus has very much the facies of a Reduviid, of the group

Piratine. The anterior femora are enormously incrassate. The antenne are 5-jointed,

1-3 moderately stout, 4 and 5 very slender, 3-5 subequal in length, 2 about twice as

loug as 1 and a little Jonger than 3. The rostrum is short and very stout, apparently

4-jointed. The elytra have a narrow linear clavus; the whole of the outer’ portion

of the corium to the apex, exterior to the oblique median nervure, is regarded by

Prof. Uhler as an embolium, but there is no cuneus; on the inner portion of the

corium, a little beyond the apex of the scutellum, there is a triangular opaque space

of a similar texture to the membrane; the membrane (not mentioned by Prof. Uhler)

is moderately developed in the Antillean types, Tonger in the specimens from

Guatemala.

from Grenada described by Prof. Uhler, and have the membrane more developed,

extending to a little beyond the apex of the abdomen; but these differences are not

sufficient to warrant the separation of the mainland form.

PAGASA.

Pagasa, Stal, Rio Jan. Hemipt. ii. p. 60 (1862) ; Hemipt. Afr. ii. p. 88; Enum. Hemipt. iii.

pp. 107, 108.

Stal separated the American forms allied to Prostemma, Lap., under a separate genus,

Pagasa, chiefly on account of the longer rostrum and the presence of a collar to the

pronotum in front; but it is doubtful if it can be maintained, one of his species being

intermediate in these respects. The Palearctic forms known to me have, however,

a relatively shorter second joint to the rostrum, this reaching only to about the

middle of the eyes, whereas in the American species it extends as far as or beyond

the eyes. Our three representatives are very widely distributed and they may be

separated thus :—

coarse long sete on their outer edge; piceous, the head rufo-testaceous above, the anterior lobe of the

pronotum nigro-eneous, with a triangular ochreous mark on the disc at the apex; the scutellum fusco-

testaceous, darker in front, with a pale central line, the fovee black; the clavus and corium fuscous,

streaked with fusco-testaceous between the nervures, the corium broadly black at the apex and with two

ochreous marks at about the middle of the apical margin; the membrane fuscous, black at the base, the

nervures paler; the antenne, rostrum, and legs fusco-testaceous; the surface shining, the scutellum

and elytra opaque, a space along the outer part of the corium (extending from the base to the transverse

plica) excepted. Head smooth, the eyes large and rounded, the ocelli prominent and comparatively

large; rostrum stout, reaching to about the middle of the anterior coxe, joint 3 slightly longer than 2,

2 extending only as far as the posterior margin of the eyes; antenne with joints 1-3 moderately

stout, 4 and 5 very slender, 2 one-half the length of 1, 3-5 long, subequal in length. Pronotum almost

smooth, as broad as long, with a fine shallow curved transverse groove separating off the collar in front,

the transverse sulcus before the base impunctate. Scutellum bifoweate on the disc. Elytra with three

regular rows of punctures —two rows on the clavus and.one on the inner basal half of the corium; the

shining outer portion of the corium obsoletely rugulose, limited posteriorly by a distinct transverse

plica; the membrane extending to a little beyond the apex of the abdomen. Anterior femora greatly

incrassate, denticulate beneath. Anterior tibize strongly curved inwards, widening on the inner side to

the apex and also denticulate within.

the spotted elytra, which have a much broader shining space at the sides, and the

shorter and stouter rostrum (in P. @nescens the second joint is fully as long as the

third). From P. pailidiceps, Stal, it may be known by the less elongate head, the

much shorter rostrum, the broader shining space at the sides of the elytra, &. The

present species has a distinct transverse pallid plica towards the apex of the corium

extending inwards from the costal margin, indicating the point of separation between the

cuneus and embolium, as exhibited in the Anthocoride.

pilose; very shining, nigro-seneous, the scutellum black and opaque, the legs, antenne, and rostrum

varying in colour from nigro-pieeous to testaceous. Head smooth, the eyes large, oval as seen from

above, the ocelli very small; rostrum reaching the anterior coxa, joints 2 and 3 subequal in length,

2 extending as far as the posterior margin of the eyes; antenne with joint 2 about half the length of 1,

3-5 subequal in length, 3 a little thickened towards the apex. Pronotum smooth, longer than broad,

with a fine straight transverse groove separating off the collar in front, the transverse sulcus before the

base with a row of punctures, Scntellum with two small fovee on the disc. Abdomen transversely

strigose, the basal segments punctured. LElytra irregularly obsoletely punctate and with rows of more

distinct punctures along the sides of the prominent nervures. Anterior femora greatly incrassate,

denticulate beneath. Anterior tibie in both sexes broadly and angularly dilated at the apex within.

Macropterous form.—Corinm extending to beyond the middle of the abdomen; the membrane reaching the

apex of the latter.

Brachypterous form.—Corium not reaching the middie of the abdomen, sinuate on the outer side towards

the apex; the membrane reduced to a narrow stripe or entirely absent.

Eleven specimens, three of which are macropterous. The above description is taken

from the Central-American examples: they do not quite accord with the colour given

by Stein, and Stai’s diagnosis of P. nitida is very brief*. Those from the Los Altos

region of Guatemala (7000-10,500 feet) have the legs, antenne, and rostrum more or

less infuscate. Berg (Hemipt. Argent., Suppl. p. 105) has recorded P. nitida from

Buenos Ayres. Stal’s type has been examined. In the Stockholm Museum there is a

larva of a Pagasa from Mexico (Sallé) possibly belonging here; but it has the anterior

tibize widened from a little beyond the middle to the apex.

Some authors, including Stal, adopt the name Coriscus, Schrank [Fauna Boica, i. 2,

p. 99) C. dauct (=Alydus calcaratus, Linn.) as the type, it cannot be used. Various

subgenera of Nabis have been proposed by Reuter and others, two only of these being

represented within our limits. In this genus all the tarsi are 3-jointed, the anterior

and intermediate tibiz have a lobe at the apex *, and the rostrum and antenne are

4-jointed. Seven species are now known from within our limits, one of them being

the holarctic N. ferus (Linn.)f. The undeveloped or brachypterous forms cannot

always be satisfactorily determined in the absence of developed examples; and in at

Eight macropterous females and one undeveloped male are referred to this species,

described from females only. In the undeveloped specimen from Cuernavaca the

elytra reach the base of the sixth abdominal segment (in the undeveloped type they

are stated to extend to a little beyond the middle of the abdomen), and the membrane

is nearly as long as the clavus. The scutellum has a small pallid spot on each side,

not mentioned by Reuter. The outer apical angles of the sixth connexival segment

are rectangular in the male.

A brachypterous male (fig. 24) and female have also been received from Omilteme

(with developed forms) with the elytra barely twice the length of the scutellum and

conjointly truncate at the apex: there can scarcely be any doubt that they belong

to the same species, and that the elytra vary in development in this insect, as well

as in WV. nigriventris.

The macropterous type ( 2 ) in the Stockholm Museum has been examined.

A common species in Mexico and Guatemala. Very like W. crassipes, but smaller,

narrower, and less robust, the anterior femora less incrassate. Of the fifty-one

NABIS. 303

specimens in our collection, two only (@) are brachypterous; they measure from

6—7 millim. in length. The types of V. nigriventris, Stal, and WV. sericans, Reut., both

brachypterous females, are before me: Stal’s specimen, which is discoloured, has the

elytra short, rounded at the apex, with a narrow membrane, and the ventral and dorsal

surfaces of the abdomen nigro-piceous; that of Reuter has the elytra still shorter,

rounded behind, and without trace of membrane, and the abdomen paler.

The two brachypterous specimens received by us (from Omilteme and Capetillo

respectively) merely differ from Stal’s type in having slightly longer elytra. <A

developed male from Cuernavaca is figured.

We possess a long series of this species, including four brachypterous examples

(three males and one female) ; from Vera Cruz both brachypterous and macropterous

specimens have been sent by Mr. H. H. Smith. J. sordidusis very like NV. nigriventris,

but it is more elongate, the head is relatively longer and the legs also, the abdomen

is broadly pale down the middle beneath and has two pale vitte along the centre

above, the corium has a whitish node on one of the nervures towards the apex, &c.

The black or fuscous spots along the connexival margins are sometimes indistinct or

obsolete in immature examples. The insect varies a good deal in size, the brachypterous

specimens being smaller than the others. The brachypterous type from Vera Cruz

has been examined, and we have one exactly like it from Atoyac. The brachypterous

males from Teapa and Vera Cruz are not separable from the North-American type (@ )

of WV. pallescens, Reut., which appears to be nothing more than a pallid form of the

_ present species. We figure a developed male and an undeveloped male and female, all

trom the State of Vera Cruz.

4, Nabis constrictus, n. sp. (Tab. XVIII. figg. 29, 2 ; 30, apex of the

abdomen from above, showing the genital claspers, ¢.)

Macropterous form.—Moderately elongate, narrow, subopaque, sparsely pilose, the legs also with very long

fine projecting hairs; stramineous or testaceous, the pronotum with the sides of the anterior lobe, a spot

at the lateral angles, and three lines on the disc of the posterior lobe, the elytra with the clavus in part,

a common transverse fascia about the middle, sometimes so extended as to leave only a space at the sides

of the corium below the base pale, and the nervures of the membrane in part, fuscous or dilute fuscous ;

the corium in fresh specimens with two posteriorly confluent crimson streaks at the apex, the nervures

usually pale; the pleura, a row of spots along the sides of the connexivum, a narrow vitta down each

side of the venter, the apex of the second antennal joint, the apices of all the tibie, and a narrow annulus.

before the apices of the hind femora, black or fuscous, the tibie usually with at least one darker ring

near the base and the anterior and intermediate femora with a similar ring near the apex. Head shorter

than the pronotum, the eyes small, prominent, and coarsely faceted ; antenne very slender, as long as

the body, joints 2-4 nearly equal in length, 1 shorter than 2 and about as long as the head. Pronotum

about as broad as long, the posterior lobe and the collar rugosely punctate, the basal portion of the

anterior lobe almost smooth. Elytra constricted at the sides below the base, extending some distance

beyond the abdomen, and in the male almost covering it externally. Abdomen rounded at the sides in

the female, more parallel-sided in the male, the connexivum moderately wide. Anterior and intermediate

legs with the femora beneath, and the tibie within, finely denticulate.

Length 63-8, breadth 14-23 millim. (¢ 9.)

Hab. Mexico, Atoyac and Teapa (H. H. Smith); Guatemaa, Batheu in Vera Paz,

Numerous examples, all macropterous. [Easily distinguishable from the other

Central-American species by the rugose posterior lobe of the pronotum and the laterally

constricted elytra. The coloration of the elytra is somewhat variable and difficult to

describe, and it is only in fresh examples that the crimson streaks are visible at the

apex of the corium. The long scattered hairs on the legs are very fine. The membrane

usually has a patch behind the apex of the corium and the tip pale. A Chiriqui

specimen is figured.

Hab. Mexico, Teapa (7. H. Smith).

A small narrow species, flavo-testaceous in colour, with the pronotum, scutellum,

clavus, corium, and membrane streaked with fuscous or brownish; the apex of the

second antennal joint and the apices of the tibiz blackish, the rest of the legs speckled

and annulated with fuscous, the femora and tibie with scattered strong sete arising

from the fuscous dots; the pronotum with the posterior lobe and the collar closely,

finely punctate. In the brachypterous form the elytra and the upper surface of the

abdomen are streaked with fuscous or blackish. The abdomen is closely pubescent,

above and beneath. Six macropterous specimens were found at Bugaba and a pair of

brachypterous ones at Teapa. The latter agree perfectly with the others in their

general structure. JV. signatus belongs to the subgenus Hoplistoscelis, Reut.

types of which I have seen), is very like the Mexican and Guatemalan specimens, but

it has the legs and elytra more thickly speckled with fuscous.

CARTHASIS, n. gen.

Head with the ante-ocular portion cylindrical and longer than the post-ocular portion, transversely grooved

between the eyes, without ocelli, the eyes rounded, prominent, and coarsely faceted ; rostrum reaching

nearly as far as the base of the pronotum, 4-jointed, joints 2-4 slender, 2 as long as 3 and 4 united ;

antenne inserted at the apex of the short oblique cylindrical antenniferous tubercles, 4-jointed, elongate,

slender, joints 1 and 2 stouter than the others, 1 and 2 subequal in length, 3 a little shorter than 2, 4 one-

half longer than 3. Pronotum longer than broad, strongly constricted about the middle ; the posterior lobe

transversely convex; the anterior lobe longer and narrower than posterior one, with the inferior lateral

portions obliquely widening forwards to the points of insertion of the anterior legs, and shallowly

transversely grooved in front. Scutellum triangular, moderately large. Elytra extending to the apex

of the abdomen and almost covering it, constricted below the base, with a narrow clavus, the corium

reaching to a little beyond the middle of the membrane and with a sinuous median nervure, the membrane

without distinct nervures. Abdomen (@) ovate, with a very narrow connexivum. Legs slender, the

anterior pair raptorial and inserted near the apex of the propleura; anterior coxe elongate, about half

the length of the tibie ; anterior femora feebly incrassate, denticulate beneath ; all the tibie with a spongy

lobe at the apex, extending to about the middle of the very slender tarsi, which are formed of one joint

only ; claws simple; anterior tibize denticulate within. Body narrow, slender.

This genus is allied to Vadis, but differs from it in the form of the pronotum, the

absence of ocelli, the relatively longer anterior coxe, the structure of the tarsi, &c.

In the long anterior coxe and the position of the anterior legs it approaches the

subfamilies Emesine and Bactrodine of the Reduviide. ‘The tarsi are uni-articulate,

and at the apex of each of the tibie there is a spongy lobe.

Hab. Panama, Bugaba, Caldera, David, Tolé (Champion).

Five specimens of this delicate insect have been found ; three of them are somewhat

Fam. ANTHOCORIDA.

In Dr. Reuter’s comprehensive and masterly monograph of this family (1884) nine

species only are mentioned from within our limits, and these from Mexico. It is

therefore not surprising that many of the Central-American forms are new, both as

regards genera and species. Unfortunately several of them are represented by single

(carded) examples only, and I have not always been able to make out satisfactorily the

neuration of the wings and the form of the orifice of the odoriferous sac, the main

characters relied upon by Dr. Reuter in his system of classification. Since tlie

publication of the ‘Monograph,’ Prof. Uhler has given a list of the numerous species

obtained by Mr. H. H. Smith in the Antillean islands of St. Vincent and Grenada

(P. Z. 8. 1894, pp. 156, 157, 198-202); several of these also inhabit our region,

whence upwards of fifty are here recorded. Of the three subfamilies adopted by

Dr. Reuter, one only, the Anthocorine, is represented in Central America. All our

specimens are macropterous.

Subfam. ANTHOCORINA.

Division LYCTOCORARIA, Reuter.

The species of this section of the Anthocorine have the third and fourth antennal

joints much more slender than the preceding joints, and clothed with long projecting

hairs, Dr. Reuter includes in it only the forms with a hamus in the cell of the wings;

but one of the new genera here characterized without a hamus in the cell is so nearly

allied to Lastochilus in other respects that it seems best placed here.

Nine specimens have been seen from within our limits. This species is recognizable

by its pallid coloration and the rather coarsely subseriately punctured clavus, there being

also a row of punctures along the inner portion of the corium. In all the examples

examined, including one of the types from Texas, there is a rather deep fovea on the

disc of the anterior lobe of the pronotum behind, a character not mentioned by

Dr. Reuter. Found in plenty by Mr. H. H. Smith in the Island of Grenada.

5. Lasiochilus foveicollis, n. sp.

Oblong-ovate, somewhat thickly pilose and also clothed with long, scattered, erect hairs, the margins of the

embolium ciliate ; shining, the elytra rather duller, the apical portion of the scutellum opaque; piceous,

the elytra fuscous, with the shoulders ochreous and the cuneus black, the antenne obscure testaceous, the

rostrum and legs flavescent. Head about as broad as long, smooth, the eyes rather small; rostrum

reaching the intermediate coxe ; antenne with joints 1 and 2 stout, 2 two and one-half times the length

of 1 and longer than 3 or 4, the latter very slender and subequal. Pronotum not twice as wide at the

base as at the apex, the sides almost straight; the anterior lobe smooth, and with a deep oblong fovea on

the middle of the disc behind; the posterior lobe depressed on the disc and transversely rugulose,

Lasiochili by its very small size, the rather shining elytra, the deeply foveate pro-

notum, and the stout first and second joints of the antenne. From L. fusculus, Reut.,

L. varicolor, Uhi.*, and L. fraternus, Uhl., it may be separated by the more distinctly

punctured elytra, &c. |

6. Lasiochilus sulcatus, n. sp.

Oblong-ovate, thickly pilose and also clothed with long, scattered, erect hairs, the margins of the embolium

ciliate ; shining, the depressed portion of the scutellum and the clavus opaque, the rest of the elytra

slightly shining; rufo-testaceous, the elytra fusco-testaceous, with the sides at the base broadly and the

transverse plica ochreous, the meso- and metapleura piceous, the antenne, rostrum, and legs flavescent,

the eyes black. Head about as broad as long, smooth, the eyes small; rostrum nearly reaching the

intermediate cox; antenne elongate, joints 1 and 2 moderately stout, 2 two and one-half times the length

of 1 and scarcely longer than 3 or 4, the latter with very long projecting hairs. Pronotum nearly twice

as broad at the base as at the apex, in front as wide as the head (with the eyes), the sides slightly sinuate ;

the anterior lobe almost smooth and with a very distinct narrow median sulcus; the posterior lobe

depressed on the disc and transversely rugulose. Scutellum, except in front, transversely rugulose.

Elytra with the clavus, corium, embolium, and cuneus finely but distinctly punctate, the punctuation

close on the clavus and more scattered elsewhere; the embolium broad at the apex and as wide as the

corium; the membrane with a single (outer) nervure only distinct. Orifice of the metastethium short,

backwardly curved.

Length 2 millim, (@.)

Hab. Pawyama, David in Chiriqui (Champion).

One specimen. Near L. punctipennis and L. microps, but smaller and paler, with

the longitudinal sulcus on the anterior lobe of the pronotum extending forwards to the

7. Lasiochilus divisus, n. sp.

Elongate, narrow, somewhat thickly pilose and also clothed with long, scattered, erect hairs, the margins of

fhe embolium ciliate; shining, the depressed portion of the scutellum and the clavus opaque, the rest

Scutellum, except in front, rugulose. Elytra with the clavus rather coarsely, subseriately punctured, the

corium, embolium, and clavus more sparsely and more finely punctate; the embolium broad at the apex,

and there as wide as the corium ; the membrane with a single (outer) nervure only distinct. Orifice of

the metastethium short, backwardly curved.

Length 2% millim. (2.)

Hab. Mexico, Teapa in Tabasco (H. H. Smith)—Antiues, Grenada.

One immature example has been received from Mexico, and there is a second, from

Grenada, in the British Museum, both collected by Mr. H. H. Smith. Narrower and

more elongate than L. pallidulus, the pronotum broader in front and with anterior

lobe deeply sulcate down the middle, the corium, embolium, and cuneus sparsely,

distinctly punctate, the pronotum less narrowed anteriorly and more rounded at the

sides in front. It has the pronotal groove deeper than in L. sulcatus, from which the

present insect also differs in its more elongate shape. ‘The pilose elytra &c. separate

it from Solenonotus.

LASIOCHILOIDES, n. gen.

Head (including the eyes) broader than long, the produced anterior portion broad, moderately long, and

narrowing forwards, the eyes small; rostrum reaching the middle of the metasternum ; antenne with

joints 3 and 4 very slender, clothed with long projecting hairs. Pronotum trapezoidal, wide and convex

in front, with a short collar placed behind the rounded anterior angles, the sides margined anteriorly, the

base arcuate-emarginate. Scutellum flattened behind, Elytra extending beyond the abdomen, with

the clavus, corium, embolium, and cuneus distinctly punctured, pilose, the embolium closely ciliate along

the outer edge, the membrane with a single distinct nervuare. Wings with the hamus issuing a little

beyond the decurrent nervure. Orifice of the metastethium long, curving forwards externally. Abdomen

with several very long bristly hairs at the apex, the terminal genital segment asymmetrically formed in

the male. Legs short; anterior and posterior femora greatly, the intermediate pair more feebly,

incrassate, the anterior pair denticulate along their lower edge ; anterior tibie minutely serrulate along

their inner edge, the apex widened and with a short spongy fossa on the inner side. Body narrow,

elongate, parallel.

The single species referred to this genus has very much the facies of a Scoloposcelis* ;

but differs from it in the shape of the head and pronotum, the very slender third and

fourth antennal joints, the punctured and pilose elytra, &c. From Lasiochilus it may

‘be separated by the form of the orifice of the metastethium, the greatly incrassate

anterior and posterior femora, the elongate, parallel shape, &c.

1. Lasiochiloides denticulatus, n. sp. (Tab. XIX. fig. 3.)

3. Elongate, narrow, shining, the elytra rather dull; clothed with a few erect hairs, the elytra thickly and

shortly pilose, the margins of the embolium closely ciliate, the abdomen with several very long bristly

hairs at the apex; piceous, the elytra with the sides below the shoulders broadly, and the transverse

plica, ochreous (the ochreous coloration at the base extending down the embolium and covering the basal

portion of the corium), the membrane fuscous; the head in front, the antenne, rostrum, and legs

more or less testaceous, the femora infuscate. Head smooth, about as long as broad, the interocular space

about three times the width of one of the eyes; antenne with joints 1 and 2 moderately stout, 3 and 4

very slender, 1 reaching as far as the apex of the head, 2 three times as long as 1 and longer than

with a row of punctures along the inner edge. Abdomen with a single long genital clasper on the left

side only.

Length 33 millim.

Hab. Guatemata, Cerro Zunil 4000 feet (Champion).

LASIOCOLPUS.

Lasiocolpus, Reuter, Monogr. Anthocorid. pp. 5, 27 (1884).

This genus was based upon a single species from Mexico, which is now known to

extend southwards to Panama. A second is now added. Lasiocolpus is chiefly

recognizable by the very elongate rostrum.

1, Lasiocolpus sinuaticollis. (Tab. XIX. fig. 5, ¢.)

Lasiocolpus sinuaticollis, Reut. Monogr. Anthocorid. p. 28".

Oblong-obovate, thickly pilose, the head and pronotum shining, the elytra duller, the exposed portion of the

scutellum and the clavus opaque or subopaque ; piceous or fuscous above, paler beneath, the apex of

the scutellum, the base and inner edge of the corium, the outer portion of the embolium, and a small

spot at the inner apical angle of the latter, sometimes ochreous, the antenne obscure testaceous, the legs

and rostrum flavo-testaceous, the hairs on the elytra fuscous. Head almost smooth; antenne elongate,

fully reaching the apex of the embolium, pilose, and also clothed with very long, scattered, projecting

hairs, joint 2 filiform, about three and a half times the length of 1, 3 and 4 very slender, 3 shorter

than 2 and a little longer than 4. Pronotum deeply sinuate at the sides, the collar rugulose, the anterior

lobe almost smooth, the posterior lobe rugosely punctured. Scutellum transversely rugose. Elytra with

the clavus densely, and the inner portions of the corium and embolium sparingly, punctured. Orifice

of the metastethium short and backwardly curved.

Length 4-5 millim. (¢ 9.)

Hab. Mexico, Vera Cruz (Sal/é, in Mus. Hoim.'); Guatemaua, Cerro Zunil (Champion);

Panama, Bugaba (Champion).

The three specimens obtained by myself are smaller than the type (@ ), now before

me, which, however, does not measure more than 5 millim. in length.

The single example from Guatemala has the apex of the scutellum and some marks

on the elytra pale.

2, Lasiocolpus minor, n. sp.

Oblong-obovate, thickly pilose, the head and pronotum shining, the elytra duller, the exposed portion of the

scutellum and the clavus opaque; fuscous or ferrugineo-fuscous above, rufo-testaceous beneath, the corium

and embolium more or less ochreous at the base, the antenne testaceous, the legs and rostrum flavo-

testaceous. Head almost smooth; antenne elongate, pilose, and also clothed with very long, scattered,

projecting hairs, joint 2 three times as long as 1, 3 and 4 very slender, subequal in length, each slightly

shorter than 2. Pronotum as in L. sinuaticollis. Scutellum transversely rugulose. Elytra with the clavus

densely, and the inner half of the corium sparsely, punctured, the embolium with a regular impressed row

of punctures near its inner margin. Orifice of the metastethium short, close to the posterior coxe,

backwardly curved.

Length 3-33 millim. (d 92.)

Hab. Panama, Buguba (Champion).

Five specimens. Very like Z. stnuaticollis, but much smaller, the third antennal

joint less elongate, the scutellum less rugose, the embolium with a single regular row

of punctures near its inner edge. L. elegans, Reut., from Colombia, seems to be an

allied form.

EULASIOCOLPUS.—LASLOCOLPOIDES. 313

EULASIOCOLPUS, n. gen.

Head (with the eyes) wider than the apex of the pronotum, broadly produced in front; eyes very large, oval,

. reaching to near the anterior margin of the pronotum, and separated by a space of the width of one of

them ; rostrum reaching the intermediate coxe ; antenne rather slender, joints 3 and 4 very slender, 2-4

with long projecting hairs. Pronotum transverse, strongly sinuate at the sides, broadly and shallowly

arcuate-emarginate at the base, with a distinct collar in front, the sides very narrowly and obsoletely

margined, the anterior lobe smooth and convex, and separated from the short posterior lobe by a deep

transverse groove. Scutellum deeply transversely sulcate beyond the middle, the apical portion flattened.

Elytra almost smooth, with moderately wide embolium, the membrane with a single (outer) nervure

distinct. Wings with the hamus issuing beyond the decurrent nervure. Anterior and posterior cox»

almost contiguous. Metasternum carinate down the middle. Orifice of the metastethium transverse,

curving a little forwards externally. Terminal genital (ventral) segment of the male asymmetrically

formed, with a deep sulcus or opening on the right side only. Legs elongate; anterior femora strongly,

the posterior pair moderately, incrassate; the tibie setose. Body narrow, oblong-obovate, shining, almost

smooth, clothed with scattered pubescence and a few long erect hairs, some of which project beyond the

apex of the abdomen.

This well-marked genus belongs to Reuter’s section Lyctocoraria, and it seems to

be nearest allied to Asthenidea. The very large oval eyes, smooth, shining body, dull

elytra &c., render it easy of recognition. The sides of the pronotum are very deeply

sinuate, as in Lasiocolpus.

1. Eulasiocolpus megalops, n. sp. (Tab. XIX. figg. 6, 64,3; 7, 2.)

Black, the antenna, rostrum, cox, and legs testaceous or flavo-testaceous, the posterior femora sometimes

infuscate at the apex; the elytra with a subtriangular patch at the base exterior to the clavus, the inner

margin of the corium beyond the clavus, and a spot at the inner apical angle of the embolium, ochreous,

the membrane with a transverse flavo-hyaline patch adjoining the apex of the cuneus; above and beneath

smooth and shining, the posterior lobe of the pronotum and the flattened apieal portion of the scutellum

transversely rugulose; the elytra opaque, with the cuneus and membrane shining; clothed with long,

erect, scattered hairs and also very sparsely pilose, the elytra with deeumbent golden hairs, Head with

the eyes about as long as broad; antenne moderately long, joint 1 reaching the apex of the anterior

portion of the head, 2 rather more than three times the length of 1, 3 amd £ subequal in length, each

shorter than 2, Elytra with a single impressed row of punctures near the inner edge of the embolium,

Length 3-33 millim. (d 9.)

Hab. Guatemaua, El Tumbador, Las Mercedes, Cerro Zunil (Champion); Panama,

Bugaba, Volcan de Chiriqui (Champion).

Found in plenty in Chiriqui, more sparingly in Guatemala, on the Pacific slope.

The specimens were obtained by beating the branches of fallen trees in forest-clearings.

The transverse flavo-hyaline space on the membrane is not always visible unless the

elytra are opened.

LASIOCOLPOIDES, n. gen.

Head longer than broad, the produced anterior portion stout and about as Iong as the eyes;. eyes (2) large,

oval; rostrum extending to a little beyond the anterior coxe; antenne with joints 3 and 4 very slender,

1 and 2 considerably stouter, 2-4 sparsely pilose, with very long projecting hairs intermixed. Pronotum

trapezoidal, rapidly narrowing from the base forwards, margined and feebly sinuate at the sides, with a

short well-defined collar placed before the declivous anterior angles, the base shallowly arcuate-emarginate.

Scutellum transversely sulcate beyond the middle, with the apical portion flattened. Elytra very distinctly

and subseriately punctured, pilose, the embolium ciliate externally, the latter rather narrow and at the apex

about half the width of the corium, the membrane with three nervures, the outer one only prominent.

Wings with the hamus issuing beyond the decurrent nervure. Orifice of the metasthethium short,

curving forwards externally, Anterior and posterior coxe narrowly, the intermediate coxe more broadly,

separated. Legs elongate, the femora incrassate, the tibiee clothed with long projecting hairs. Body

oblong-obovate, pilose.

The single species referred to this genus is allied to Lastocolpus, Reut., but differs

from it in having the orifice of the metastethium curving forwards (instead of back-

wards), the rostrum very much shorter, the pronotum less sinuate at the sides, the

scutellum shining, the punctuation of the elytra subserially arranged, &c. From

Asthenidea it may be known by the longer head and pronotum, the large eyes, the

stouter first and second joints of the antenna, the pilose elytra, the long, hairy legs, &c.

1. ‘Lasiocolpoides ciliatus,n. sp. (Tab. XIX. fig. 8.)

Shining, nigro-piceous or piceous, the base of the embolium, the clavus, corium, legs, and antenn obscure

testaceous, the membrane fuscous, flavescent towards the base; the elytra (the membrane excepted) thickly,

the other parts more sparingly, clothed with long semierect hairs, the head and pronotum with still longer

hairs intermixed. Head smooth, deeply bifoveate between the ocelli; antenne rather elongate, joints

1 and 2 moderately stout, 3 and 4 very slender, 2 slightly thickening outwards, and about three times as

long as 1, 3 and 4 equal in length, each much shorter than 2. Pronotum in front not wider than’ the

base of the head, smooth, the posterior lobe flattened on the disc and, as well as the apex, transversely

rugulose. Scutellum with the apical portion slightly rugulose. Elytra with the clavus, a space along the

middle excepted, and the inner half of the corium densely subseriately punctured, the embolium also with

a row of punctures along the inner edge.

Length 4,443 millim. ( 2.)

Hab. Guatemata, Quiché Mountains and San Gerénimo (Champion).

Two specimens, one of which is imperfect.

PLOCHIOCORIS, n. gen.

Head longer than broad, exserted, the produced anterior portion stout, the ocelli narrowly separated; eyes

large, oval (as seen from above), and distant from the anterior margin of the pronotum; rostrum reaching

to the anterior coxe ; antenne elongate, joints 1 and 2 moderately stout, 1 reaching a little beyond the

anterior process of the head, 2 cylindrical, nearly four times as long as 1, and as long as 3 and 4 united,

3 and 4 very slender, subequal in length, 2-4 clothed with very long projecting hairs. Pronotum

trapezoidal, short, much narrowed anteriorly, deeply transversely bisulcate on the disc, the anterior

sulcus extending downwards across the pleura and separating off the collar in front, the anterior lobe

also suleate down the middle, the sides immarginate and concave, the base feebly emarginate. Scutellum

depressed behind. Elytra subparallel, elongate, extending far beyond the abdomen, clothed with very

long hairs; embolium very narrow in its baxal half, broad behind and there nearly as wide as the corium ;

membrane with two distinct nervures. Wings without trace of a hamus in the cell. Orifice of the

metastethium long, transverse, nearly reaching the pleural groove, curving a little forwards externally.

Legs rather elongate, the femora feebly incrassate, the tarsi 3-jointed.

Following Dr. Reuter’s system of classification, this genus belongs to the Xylocoraria,

but the antennal structure is so like that of Lasiochilus and its allies that I prefer to place

it in the same division of the Anthocorine. The relatively very elongate second antennal

joint and the peculiarly formed pronotum are its chief characteristics.

Elongate, subparallel, shining, the pronotal sulci and the apex of the scutellum opaque; sparsely clothed with

very long semierect hairs, with a few erect ones intermixed, the margins of the pronotum and embolium

ciliate; the antennal joints shortly pilose and also with numerous very long projecting hairs; the

legs pilose, with long erect hairs intermixed; piceous, the elytra testaceous, with the apical half of

With one exception, all the species of this genus are American. It differs from

Lasiochilus in having the pronotum margined at the sides and with the short collar

placed before the anterior angles, the elytra finely pubescent (instead of being clothed

with long hairs) and with rather narrow embolium, the orifice of the metastethium

curving forward (instead of backward), &c. The flattened apical portion of the

scutellum (as in Lasiochilus) is more or less opaque. If Calliodis (the mutilated type

of which I have not seen) should prove to be synonymous with Asthenidea, the latter

name will have to be dropped. ‘The four Central-American species may be separated

thus :—

Three specimens, agreeing with the types in the British Museum. Recognizable

by the dull, finely pubescent, ochreous elytra, which have a common transverse fascia

crossing the apices of the clavus, corium, and embolium, as well as the cuneus, nigro-

fuscous; the legs are partly piceous; the apical half of the scutellum is opaque; the

orifice of the metastethium is short and curved forward.

Hab. Mexico (Bilimek, in Mus. Vind. Ces.'), Vera Cruz (Sallé, in Mus. Holm.*),

* Dr. Reuter (op. cit. p. 103) sinks this name as a synonym of Poronotus constrictus (Stil), but this is a

mistake. The type of the latter has the pronotum very deeply emarginate at the base, the clavus extremely

coarsely punctured, the embolium very broad behind, and the wings without a hamus in the cell. Poronotus, as

represented by P. constrictus, is a valid genus, near Cardiastethus.

318 HEMIPTERA-HETEROPTERA.

Teapa (H. H. Smith); Guaremata, Senahu and San Gerdnimo in Vera Paz, Cerro

Zunil, Las Mercedes, Duefias (Champion); Nicaragua, Chontales (Janson).

Not rare in Guatemala. Varies in colour, as noted by Dr. Reuter, the head,

pronotum, scutellum, and body being sometimes piceous, and the cuneus slightly

infuscate. The legs, however, are constantly pale. The embolium is rather narrow

throughout, it being only about one-third of the width of the corium at the apex.

From the similarly-coloured species of Cardiastethus it may be distinguished by the

less deeply emarginate base of the pronotum. ‘The Mexican types have been seen.

3. Asthenidea picta.

Two specimens. In this insect the elytra are dull and very finely pubescent, ochreous

in colour, with the cuneus in great part fuscous or black; the apical half of the

scutellum is opaque; the orifice of the metastethium is short and curved forward ;

the pronotum is piceous (as in some of the Antillean examples) and margined at the

sides; and the legs are pale.

4, Asthenidea bifasciata, n. sp. (J'ab. XIX. figg. 13, 134.)

Ovate, shining, the apex of the scutellum opaque, finely pubescent and also clothed with long, scattered, erect

hairs; testaceous or rufo-testaceous, the scutellum and the meso- and metasternum piceous or fuscous,

the head sometimes slightly infuscate, the eyes black; the elytra ochreous, with a broad irregular

transverse fascia across thé middle of the coriaceous portion, and the cuneus, except along the outer

margin, fuscous, the membrane slightly infuscate; the antenne, legs, and rostrum testaceous, the basal

half of the latter piceous. Head smooth, as broad as long, the eyes rather small; rostrum reaching the

intermediate coxe ; antenne with joints 1 and 2 rather slender, 2 thickened at the apex, three times as

long as 1, and longer than 3 or 4, the latter very slender, joints 2~4 shortly pilose and also with long

projecting hairs. Pronotum moderately narrowed anteriorly, the sides obsoletely margined towards the

apex, the anterior angles rounded and deflexed; smooth, the posterior lobe depressed on the disc in front

and faintly transversely rugulose. Scutellum transversely rugose behind. Elytra with the clavus and

inner half of the corium closely, finely punctate; the embolium narrow, at the apex less than one-third

_ the width of the corium. Orifice of the metastethium moderately long, curved forward externally.

Length 2} millim. (9.)

Four specimens. ‘This insect closely resembles Dr. Reuter’s figure of Calliodis

picturata (Stal), from Brazil, described from a single mutilated example, which he

places amongst the “species et genera sedis incerte ” at the end of the Anthocorine in

his Monograph. It differs, however, in being less elongate, the pronotum is more deeply

emarginate at the base, the rostrum is shorter (extending to the posterior cox in

Calliodis), and the hind angles of the pronotum are not broadly infuscate.

Macrotrachelia, Reuter, Ofv. Vet.-Ak. Férh, 1871, p. 566; Monogr. Anthocorid, pp. 55, 57 (1884).

The type and only known species of this genus is Anthocoris nigronitens, St&l, from

Rio Janeiro. Macrotrachelia proves to be well represented in Central America, whence

six species are now recorded, all abundantly distinct and easily distinguishable by the

table given below. The genus is one of the best marked amongst the Anthocoride,

and at once recognizable by the broad black stripe which extends down the middle of

the membrane to the apex. In two of the Central-American species the eyes are long

and coarsely faceted in the males. ‘The orifice of the odoriferous sac varies in form

according to the species, and the length of the rostrum also.

The Macrotrachelie closely resemble various species of Thrips.

a. Elytra shining, each with a very broad whitish or pale flavous vitta

occupying the greater part of the clavus and corium (leaving a sutural .

and a marginal black stripe); rostrum very short, not nearly reaching

the anterior coxe.

both sexes.

Length 34-4 millim. (¢ 2.)

Hab. Panama, Volcan de Chiriqui 2000 to 8000 feet (Champion).—BraziL, Rio

Janeiro !~4,

Eighteen examples. Very like If. thripiformis, but with the third antennal joint

constantly black at the apex, and the corium usually black, rarely with an indistinct

paler vitta down the shining outer portion. The eyes, as in that species, are large,

rounded, and coarsely faceted in the male. In one specimen, apparently immature, the

head and pronotum are piceous and the femora reddish. The type, now before me, is

female, not a male as stated by both Stal and Reuter.

6. Macrotrachelia opacipennis, n. sp. (Tab. XIX. fig. 20, ¢.)

Moderately elongate, narrow, subfusiform, clothed with a few scattered hairs, shining, the elytra opaque, the

outer margin of the cuneus excepted ; black, the third antennal joint ochreous, the membrane narrowly

whitish externally ; the elytra with fine lines of glistening silvery pubescence—one down the clavus, one

along its inner margin, and two down the outer part of the corium, the latter united posteriorly and

continued as a single line on the cuneus,—the posterior lobe of the pronotum and the scutellum also with

Hab. Panama, Boquete in Chiriqui 3500 feet (Champion).

One specimen. Easily distinguishable by the opaque elytra, with fine lines of

glistening silvery pubescence, the stout antenne, with the third joint wholly ochreous,

the small eyes, &c.

MACROTRACHELIELLA, n. gen.

Head as long as the pronotum, the basal portion rather long and cylindrical and forming a continuous outline

with the narrow apex of the pronotum; eyes small in the female, larger in the male, and distant from

the front of the pronotum, the ocelli placed a little behind them; rostrum short, not reaching the anterior

cox; antenne moderately elongate, rather slender, joints 3 and 4 more slender than 2. Pronotum

immarginate at the sides, with a short collar in front; the anterior lobe narrow, convex, and subconical ;

the posterior lobe short, wide, and raised, rapidly and obliquely narrowing forward, and rather deeply

arcuate-emarginate behind ; the lateral angles produced into a short outwardly-projecting tooth. Scutellum

transversely sulcate beyond the middle, the apical portion flattened. Elytra with a narrow linear embolium,

the membrane not hyaline externally, and with a single prominent nervure. Mesosternum greatly

developed, convex, with a short keel-like projection in the centre in front. Metasternum very short.

Anterior cox narrowly, the two other pairs very widely, separated. Orifice of the metastethium carinate

in front, long, and curving round externally to the anterior border of the metastethium. Legs slender,

the femora moderately thickened. Body oblong, smooth, clothed with a few scattered erect hairs.

In this curious genus the anterior lobe of the pronotum is narrow and subconical, its

apex forming a continuous outline with the cylindrical, prolonged basal portion of the

head; the lateral angles of the pronotum are dentiform; the embolium is reduced

to a narrow linear strip at the sides; and the entire surface is smooth and shining.

It is nearest allied to Macrotrachelia, but differs from that genus in the relatively

narrower anterior lobe of the pronotum, the very short metasternum, the unicolorous

membrane, &c.

1. Macrotracheliella levis, n. sp. (Tab. XIX. figg. 21, g; 22,224, 9°.)

Very shining, black, the suture of the elytra and the base of the tarsi more or less flavescent, the third and

fourth antennal joints ochreous, the membrane narrowly pale along the cuneal suture; clothed above and

beneath with a few scattered erect: hairs, some of which project beyond the apex of the abdomen, the

antenne sparsely pilose. Antenne with joint 1 extending as far as the apical process of the head, 2-4

almost equal in length, 2 nearly three times as long as 1 and thickened towards the tip.

Length 23-24 millim. (¢ 9.)

Hab. Mexivo, Teapa in Tabasco (H. H. Smith: 3); Panama, Bugaba, Volcan de

Chiriqui (Champion: 2).

Two females and one male. In the Teapa male the suture of the corium only is

flavescent, but in one of the Chiriqui females this colour extends forward along the

claval suture to a little beyond the apex of the scutellum. The third example, trom

Bugaba, is of a rufo-piceous colour, due no doubt to immaturity.

A. holarctic genus, extending in the New World to as far south as the mountains of

Panama. Of the seven described American species, four occur within our limits,

whence four others are now added. Some of the Old World forms are said to attack

lepidopterous larve. It is probable that Zopherocoris, based upon a mutilated insect

from Brazil, will prove to be inseparable from Anthocoris, one of the new species here

added * having the anterior dentate. The Central-American forms may be separated

thus ;—

Totonicapam, a female, is considerably larger than the others. Very like the Mexican

A. nigripes, but with the antenne more elongate, the femora and tibie not entirely

black, the pronotum slightly sinuate at the sides. The coloration of the legs and

antenne is variable. The specimens were probably beaten from pines.

anterior and intermediate tibize, and the bases of the tarsi, ochreous; opaque, sparsely clothed with a fine

golden pubescence. Head (except in front) rugulose, somewhat exserted, the interocular space slightly

wider than one of the eyes, the latter small; antenne rather slender, joint 2 a little more than twice as

long as 1, 3 much longer than 1 and shorter than 4; rostrum reaching the anterior cox. Pronotum

rugulose, rounded at the sides in front, very feebly depressed on the disc. Elytra parallel, smooth, the

long, joint 2 stouter and much longer than 3. Pronotum with the sides obliquely converging from the

base, the anterior angles rounded ; rugosely punctured, the posterior lobe depressed on the disc in front,

the anterior lobe almost smooth behind. Scutellum transversely rugulose. Elytra with the clavus

sparsely and very coarsely, and the other parts closely and finely, punctate. Orifice of the metastethium

very long and curved.

Length 13 millim. (¢.)

Hab. GuateMALa, near the city (Champion).

One specimen. Allied to 7. perpunctatus, but smaller, the pronotum less rugose,

the clavus sparsely punctured, the corium and embolium much more finely punctate.

5. Triphleps perpunctatus.

Triphleps perpynctatus, Reut. Monogr. Anthocorid. p. 100° (nec Uhler).

Hab. Mexico (Sallé, in Mus. Holm.'), Orizaba (H. H. Smith); Guatemaua, Duefias

(Champion).

The single specimen (2) from Guatemala differs from the type ( ¢ ) in having the

eyes smaller, the head a little more produced in front, the elytra paler, and the legs

entirely testaceous; it may belong to another species, The one from Orizaba is

immature.

6. Triphleps aterrimus, n. sp.

Broad ovate, robust, very sparsely pubescent, shining, black ; the apical half of the rostrum, the head in front

(narrowly), the tarsi, and the anterior tibize testaceous, the intermediate and hind tibiz obscure testaceous

at the base; the antenne with joint 1 piceous, 2 and 3 testaceous, and 4 ferruginous. Head broad,

rugulose, the eyes large and widely separated ; antenne rather slender, moderately long, joint 2 a little

longer than 3. Pronotum convex, feebly arcuate-emarginate at the base, rounded at the sides, the latter

margined anteriorly ; very coarsely and closely punctured, the anterior lobe almost smooth on the disc

behind. Scutellum transversely rugulose, and also minutely punctate, the transverse sulcus deep, Elytra

very coarsely, closely punctate, the punctures on the corium more scattered and. subserially arranged.

Length 2 millim.

Hab. Panama, Peha Blanca (Champion).

One specimen, probably a female. Very like 7. perpunctatus, but uniformly black

above (the apex of the anterior portion of the head only being pale), the pronotum

more convex and with the sides rounded, the corium more sparsely punctate.

PARATRIPHLEPS, n. gen.

Head very short and broad, the eyes widely separated, the ocelli placed close to their internal basal angles;

antenne short, the joints about equal in thickness, 2 not longer than the width of the head between the

eyes. Pronotum convex, deeply arcuate-emarginute at the base, and completely margined at the sides.

Scutellum transversely depressed before the flattened apical portion. Elytra with the embolium concave,

and at the apex half the width of the corium. Wings with a hamus in the cell. Orifice of the meta-

stethium long and curved, Legs short, the anterior femora stouter than the others, Body ovate, almost

glabrous.

The minute species referred to this genus, a single female specimen only of which

PARATRIPHLEPS.—MELANOCORIS. 329

has been obtained, is evidently a near ally of Triphleps perpunctatus, Reut., &c.; but

the laterally margined pronotum, and the very deeply emarginate base of the latter,

exclude it from Triphleps.

If the insects from Grenada and St. Vincent which have been determined by

Prof. Uhler as the Antillean Brachysteles pallidus, Reut., are correctly named, that

species would probably have to be included in Paratriphleps, the wings having a hamus

in the cell.

1. Paratriphleps leviusculus, n. sp. (Tab. XIX. fig. 26.)

Rufo-testaceous, shining, the eyes black, the rostrum, the anterior margin of the pronotum, and the tip of the

scutellum piceous, the posterior lobe of the pronotum slightly infuscate behind; the elytra flavescent,

mottled with fuscous, the apex of the cuneus dark, the membrane hyaline ; the antenne testaceous, with

joint 3 piceous at the apex, 4 ferruginous; tke legs flavous, the intermediate and hind tibie piceous from

the middle to the apex. Head smooth; antenne short, not reaching the hind angles of the pronotum,

rather slender, joint 2 slightly longer than 3. Pronotum convex, moderately narrowed anteriorly, the

sides slightly sinuate at the middle and rounded in front; the anterior lobe smooth, the posterior lobe

rugulose, the latter not depressed on the disc. Scutellum faintly transversely rugulose. Elytra with the

cuneus only distinctly punctate, for the rest very sparsely, minutely, indistinctly punctate, the embolium

slightly rounded along the outer edge.

Length 14 millim. (9.)

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

This insect differs from Dr. Reuter’s description of Brachysteles pallidus, from the

Islands of St. Thomas and St. John, in the almost smooth elytra, the smoother anterior

lobe of the pronotum, the partly infuscate intermediate and hind tibie, &c.

MELANOCORIS, n. gen.

Head with the ante-ocular portion a little longer than the inter-ocular, the eyes very small, the ocelli

minute, antennz short; joints 1 and 3 subequal in length, 2 twice as long as 1, 4 longer than 3;

rostrum short, only reaching the anterior coxe. Pronotum short, along the median line not quite so long

as the head, rounded at the sides anteriorly and deeply emarginate at the base, the anterior lobe scarcely

callous on the disc, and without a distinct collar in front. Scutellum flattened behind. Elytra with the

cuneus greatly developed, about one-fifth shorter than the embolium, the membrane with four prominent

nervures. Metasternum broadly rounded behind. Legs comparatively short; tarsi 3-jointed. Posterior

coxe widely separated. Orifice of the metastethium short, backwardly curved. Body broadly obovate,

opaque, the entire upper surface finely rugulose, the elytra without well-defined punctures.

This genus is allied to Tetraphleps and Acompocoris. which include various palearctic

forms found upon pine-trees. It differs from them in having the hind coxe more

widely separated, the antenne and legs much shorter, the pronotum without a distinct

collar in front and the anterior lobe scarcely callous on the disc, the entire upper

surface rugulose and opaque. The insect from which the above characters are taken

was also, I believe, found upon pine-trees, at a high elevation, in the Los Altos region

of Guatemala.

Division XYLOCORARIA, Reuter.

This section of Anthocorine, following Dr. Reuter’s system of classification, includes

a heterogeneous assemblage of genera agreeing in a single character only, viz. the

absence of a hamus in the cell of the wings. ‘This character, in one genus at least,

Scoloposcelis, is a variable one. In Solenonotus the antenne have the third and fourth

joints very slender and clothed with long projecting hairs, as in the species of

Lyctocoraria.

A very widely distributed genus, including fifteen described species, seven of which

are American. Four are known to me from within our limits. Its chief characters

are the very deeply emarginate base of the pronotum, the slender and somewhat

fusiform third and fourth joints of the antenne, the transversely sulcate scutellum, and

the absence of a hamus in the cell of the wings: these points of distinction will serve

to separate the species from the various very similar Lastochili and Asthenidee.

1. Cardiastethus tropicalis, n. sp. (Tab. XIX. fig. 28.)

Oblong ovate, shining, the elytra dull, finely pubescent and also with a few long scattered erect hairs ; piceous

or piceo-ferruginous, the elytra testaceous, with the inner portion of the cuneus blackish, the dark

coloration sometimes occupying the whole of the cuneus and extending to the apex of the embolium, the

membrane smoky ; rostrum and legs testaceous ; antenne varying in colour from piceous to almost entirely

testaceous. Head smooth, bifoveate between the ocelli; the eyes large and coarsely faceted in the male,

smaller in the female; antenne with joints 1 and 2 moderately stout, 3 and 4 slender, 2 about three

times as long as 1 and thickened towards the tip; rostrum not reaching beyond the anterior coxe.

Pronotum rounded at the sides in front, the sides distinctly margined anteriorly, the anterior lobe almost

smooth, the posterior lobe transversely rugose, strongly depressed on the disc in front, the base very deeply

emarginate. Scutellum with a broad transverse rugulose depression before the apex. Elytra subparallel

to the apex of the embolium, distinctly, not very closely punctate; the embolium narrow, at the apex

about half the width of the corium; the membrane with an inner and an outer nervure distinct. Orifice

of the metastethium long and curved.

Ten specimens. Not unlike the Palearctic C. fasctiventris (Garb.), but more shining,

the elytra more sparsely and not so finely punctate. From Asthenidea pallescens, which

is equally variable in colour, it may be separated by the deeply emarginate base of the

pronotum, &c. |

There are several examples of C. tropicalis from Grenada in the British Museum,

mixed with the series of Lastochilus fraternus, Uhler, collected by Mr. H. H. Smith.

2. Cardiastethus rugicollis, n. sp.

Oblong ovate, shining, the elytra dull; pilose and with a few long erect hairs, the margins of the pronotum

and embolium ciliate ; piceous, the elytra and antenne obscure testaceous, the legs testaceous. Head

almost smooth, a little broader than long, the eyes rather large; antenne with joints 1 and 2 moderately

stout, 3 and 4 slender and somewhat fusiform, 2 three times as long as 1; rostrum reaching as far as the

posterior portion of the anterior coxe. Pronotum very short, rugose, with the callose portion of the

anterior lobe smooth, deeply emarginate at the base and much narrowed in front, the anterior angles

_ declivous, the sides obsoletely margined anteriorly. Scutellum with a deep, transverse, rugulose depression

before the apex. Elytra somewhat closely punctate; the embolium narrow, at the apex about half the

width of the corium; the membrane with an inner and an outer nervure distinct. Orifice of the meta-

stethium long and curved.

Length 2 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith).—Antiutes, St. Vincent, Grenada.

One specimen. Smaller than C. tropicalis, the pronotum shorter, more rugose, and

more narrowed in front, the upper surface clothed with longer hairs, these projecting

laterally, so that the pronotum and embolium appear to be ciliate at the sides. The

present species is also extremely like various Lasiochili; but it may be separated from

scutellum, &c.

Some of the specimens named by Prof. Uhler as C. consimilis and C. assimilis, from

St. Vincent and Grenada respectively (P. Z. S. 1894, pp. 156, 201), no doubt belong

here: they are smaller than the insect described, and have the cuneus partly blackish.

Ovate, shining, the elytra duller, finely pubescent; nigro-piceous, the head (except at the base), the hind

angles of the pronotum broadly, and the outer margins of the elytra rufo-testacedus, the antenna, rostrum,

and legs testaceous, the two outer joints of the antenne slightly infuscate. Head broader than long,

about one-half longer than its width between the eyes, the latter moderately large; antenne with

joints 1 and 2 rather stout, 3 and 4 more slender and somewhat fusiform, 2 three times as long as 1 and

thickened towards the apex ; rostrum not extending beyond the anterior coxe. Pronotum (along the

‘median line) as long as the head, rounded at the sides, transversely rugulose, the anterior lobe smooth in

the middle, the posterior lobe flattened on the disc, the base very deeply emarginate, the anterior angles

obtuse and declivous. Scutellum with a broad, deep, transverse, rugulose depression before the apex.

Elytra closely, very finely punctate; the embolium broad, at the apex not much narrower than the

corium ; the membrane with an inner and an outer nervure distinct. Orifice of the metastethium very

long, extending outward to the submarginal ridge.

CARDIASTETHUS.—PORONOTUS. 333

We possess eight examples of this species from within our limits, two only of them

being from Guatemala. Very like C. limbatellus, but with the pronotum differently

coloured, more narrowed anteriorly, the sides less rounded, the posterior lobe smoother

and less depressed on the disc. The description is mainly taken from the Panama

specimens, the others being immature or broken. The single example with a dark

anterior lobe to the pronotum was obtained at an elevation of 8000 feet in Chiriqui.

One of Dr. Reuter’s types of C. assimilis from §. Carolina has been examined, and

it only differs from our specimens in having the elytra paler. The C. assimilis of

Prof. Uhler’s Grenada list (P. Z. S. 1894, p. 201) belongs to a different species.

PORONOTUS.

Poronotus, Reuter, Ofv. Vet.-Ak. Forh. 1871, p. 561; Stal, Hemipt. iii. p. 102.

This genus is dropped by Dr. Reuter in his Monograph. His types were Xylocoris

discifer and X. constrictus, Stal, both from Brazil. The first-mentioned species is

referred to Cardiastethus in the Monograph, and the second to Asthenidea. The name

Poronotus is here retained for the latter, the type of which, as well as a second

specimen from Mexico, I have examined. ‘This insect, incorrectly treated by Dr. Reuter

as synonymous with his Asthenidea pallescens, is closely related to Cardiastethus. The

pronotum is very deeply emarginate at the base; the deep transverse sulcus between

the anterior and posterior lobes extends completely across (it is not limited to the dise,

as in Cardiastethus); the posterior lobe is sulcate down the middle in front; the

anterior lobe is short and convex, and in front of it there is a very distinct collar.

The scutellum (as in Cardiastethus) has a broad, deep, transverse sulcus across the

middle. ‘The elytra are finely pubescent, with the clavus exceedingly coarsely punc-

tured and the other parts almost smooth; the embolium at the apex is as broad as the

corium. ‘The wings are without a hamus in the cell. The metasternum is short; the

orifice of the metastethium is long and curved backward.

Stal, Enum. Hemipt. i. p. 101.

Dr. Reuter included a single species from ‘Tropical America in this genus, his type

of which had the third and fourth antennal joints broken off. This species and two

others occur within our limits. They have the antenne formed as in Piezostethus, &c.,

the two outer joints being much more slender than the others and clothed with long

projecting hairs. Solenonotus is a near ally of the Palearctic genus Xylocoris. ‘The

three species may be separated thus :—

of which is now before me: they have the hind tibie piceous, except at the base

and apex, and the other tibie entirely testaceous. ‘The shoulders of the elytra are

ochreous.

2. Solenonotus canaliculatus, n. sp.

Narrow, shining, depressed, the flattened apical portion of the scutellum and the elytra subopaque; finely

pubescent, and also clothed with a few scattered long erect hairs, the abdomen with several very long

bristly hairs at the apex; piceous, the elytra piceous or fusco-testaceous, with the shoulders ochreous, and

the outer portions of the embolium and cuneus thence to the apex black; the antenna, rostrum, and legs

testaceous, the femora slightly darker. Head nearly as long as broad, the eyes small; antenne as in

S. nigromarginatus. Pronotum trapezoidal, very short, deeply sulcate down the middle, and obsoletely

margined at the sides, the anterior lobe almost smooth, the posterior lobe depressed on the disc and

transversely rugulose. Elytra almost smooth. Orifice of the metastethium curving forward externally.

Legs rather short, the femora incrassate, the anterior and posterior pairs very stout.

Rather broad, shining, depressed, the flattened apical portion of the scutellum opaque and the elytra dull;

finely pubescent and also clothed with a few long erect hairs, the abdomen with several very long bristly

hairs at the apex; piceous, the elytra testaceous or stramineous, with the cuneus and embolium to a

greater or less extent black, and the membrane hyaline or flavo-hyaline; the antenne, rostrum, and legs

testaceous, the femora piceous or fuscous. Head considerably broader than long, smooth, the eyes rather

large ; antenne moderately long, joints 1 and 2 stout, 3 and 4 very slender, 2—4 nearly equal in length,

2 thickened outwards and about three times as long as 1; rostrum extending to a little beyond the

anterior cox. Pronotum trapezoidal, short, somewhat deeply emarginate at the base and very finely and

obsoletely margined at the sides, more or less distinctly sulcate down the middle of the anterior Jobe, the

latter almost smooth, the posterior lobe depressed on the disc and transversely rugulose. Elytra almost

smooth. Orifice of the metastethium long, curved forward externally, and reaching to near the outer

edge of the metastethium. Legs rather short, the femora incrassate, the anterior and posterior pairs

very stout.

Length 2-23 millim. (¢ 9.)

European forms, the hamus is often present. Four species are known, three of which

are Palearctic.

Macropierous form. Narrow, obovate, dull, piceous, the elytra uniformly fuscous, the wings hyaline and

iridescent, the legs, antenna, and rostrum testaceous; the head, pronotum, and abdomen clothed with a

few long erect bristly hairs, the tibia setose, the two outer joints of the antenne clothed with very long

fine projecting hairs. Antenne moderately long; joints 3 and + very slender, elongate, and about equal

in length. Pronotum narrower in front than the head (with the eyes), the sides (as viewed from above)

straight, and rapidly converging from the base forward, the disc finely canaliculate down the middle.

Elytral neuration as in C. brasiliensis, Reut.

Length nearly 2 millim.

Hab. Panama, Bugaba (Champion).

Two specimens. Closely allied to C. minutus, Uhler, from St. Vincent and Grenada,

but larger and more elongate, the elytra longer (in the developed forms), the pronotum

with the sides straighter. C. minutus appears to be a common insect in some of the

Antillean Islands, In the elytral neuration the present insect agrees with Dr. Reuter’s

only a single specimen was preserved. It appears to tollow man everywhere in his

wanderings. |

HASMATOSIPHON, n. gen.

Head very broad, short, sunk into the pronotum up to the eyes, the latter finely faceted and moderately

prominent; rostrum extending to the middle of the posterior coxw, and received into a narrow groove

between the coxe. Pronotum truncate at the base and apex, with the explanate margins narrow

and of equal width throughout, the anterior angles very slightly produced forwards. LElytra not longer

than the median portion of the first dorsal abdominal segment, separately rounded behind, and with

the outer margins strongly reflexed. Abdomen in both sexes with the first dorsal suture straight, the

following sutures, as well as all the ventral ones, becoming more and more sinuous posteriorly. Cox

subcontiguous ; the intermediate pair separated by a thin lamella only, the posterior pair by a narrow

prolongation of the raised intercoxal process of the abdomen, the latter widening posteriorly and extending

as far as the apex of the fourth ventral segment. Tarsal claws very slender, simple. Genital segments

of the male asymmetrically formed. Fourth ventral segment in the female unemarginate on the left side

at the apex. The other characters as in Cimew.

As the late A. Dugés anticipated, the insect described by him under the name

Acanthia inodora cannot be retained in the same genus with Cimex lectularius, Linn.

The very long rostrum, the deeply inserted head, the subcontiguous intermediate and

hind coxe, the form of the pronotum, and also that of the abdomen, the laterally

margined elytra, &c., separate it at once from C. lectwlarius and its allies.

The single known species infests poultry, and it appears to be a troublesome pest

wherever it occurs. Dugés states that H. inodora is without an odoriferous apparatus,

but this is a mistake.

According to Prof. Townsend *, who describes the nymph, this insect is known in

New Mexico by the name of “coruco.” He states that “‘ when the insect once gains

access to a hen-house, it soon swarms in great numbers, infesting the inmates anil

roosts, and covering the eggs with its excrementa, which show as black specks. It is

a very difficult pest to exterminate, and has frequently been known to spread from

roosts to dwelling-houses, where it proves more formidable than the bed-bug.”’

Dr. E. Dugés has been kind enough to send us specimens of both sexes of the species

from Guanajuato.

This well-known genus includes nearly one hundred described species, few of

which are from the New World. The North-American forms, however, are numerous

and require revision. Of the ten here enumerated from within our limits, S. signoreti,

Guér. (=ornata, Stal), is the only one inhabiting the sea-coast, where fresh species

are certain to be discovered, the others being from the banks of ponds or streams.

Following Dr. Reuter’s system of arrangement, S. signoreti should form the type of

a new subgenus near Chiloxanthus, the other Central-American forms belonging to his

section Acanthia.

I have seen six specimens of this peculiar species—one from Georgia, two from Cuba,

and three from Mexico (including the type of S. ornata). The antenne are pale and

slender, with a very elongate second joint, this being longer than the third and fourth

joints united; they are finely pilose, and on the first joint there are a few short black

sete. The ocelli are very narrowly separated. ‘The upper surface of the body is rather

dull and finely pubescent. The membrane has five areole, the outer one being open

externally. The legs are more or less distinctly annulated with blackish ; they are

finely pilose, the tibia armed with short black sete. According to Prof. Uhler?? this

pale-coloured species inhabits white sandy spots near the sea-beach, as well as alkaline

deserts and the vicinity of salt springs and lakes. Stal’s type of S. ornata is figured.

2. Salda levis, n. sp. (Tab. XX. fig. 3.)

Oblong-ovate, very shining, the upper surface somewhat thickly clothed with erect blackish hairs; black, the

elytra with two distinct yellowish spots only, both marginal, one near the apex of the corium and the

other on the membrane, the latter in great part fuscous, with the apex hyaline; the antenne testaceous,

with the apex of the second joint and the base of the third infuscate, the first joint slightly darkened ;

the rostrum, coxe, and legs testaceous, the tibie and tarsi faintly annulated with fuscous. Head smooth

behind the ocelli, the latter narrowly separated; antenne elongate, moderately slender, joint 2 nearly

twice as long as 3, 3 and 4 subequal in length, all the joints shortly pubescent and also clothed with long,

fine, projecting hairs. Pronotum narrowly explanate at the sides and rapidly narrowing forwards ;

anterior lobe shallowly sulcate down the middle, limited before and behind by a distinct transverse groove,

which is impressed with a row of punctures. Scutellum slightly rugulose on the disc anteriorly. Elytra

almost smooth, the clavus with a few punctures; membrane with four areole. Legs shortly pilose, the

tibize with scattered sete,

elytra shining throughout and more sparsely pilose, the head smooth behind, the anterior

lobe of the pronotum not so deeply sulcate down the middle, the antennz not so stout.

8. Salda sulcicollis, n. sp. (Tab. XX. fig. 4.)

Ovate, very shining, the clavus (except along the suture) opaque; the upper surface thickly clothed with

long, erect, blackish hairs, between which a very short, fine, decumbent golden pubescence is visible ;

black, the elytra with two distinct yellowish or whitish lateral spots, one before the apex of the corium

and the other on the membrane, and indications of smaller scattered spots, the membrane fuscous, with

pale spots; the antenne testaceous, with the third and fourth joints, and the apex of the second, more or

less infuscate, the fourth sometimes pale at the tip; the rostrum, coxe, and legs testaceous, the tibia and

tarsi annulated with fuscous. Head rugulose behind the ocelli, the latter narrowly separated ; antenne

long and rather stout, about reaching the apex of the clavus, joint 2 one-half longer than 3, 3 and4

subequal in length, all the joints shortly pubescent and also clothed with long, fine, projecting hairs.

Pronotum very narrow in front, narrowly explanate at the sides, the latter rapidly and obliquely converging

from the base forwards; anterior lobe deeply suleate down the middle, the two callosities thus formed

being limited before and behind by a deep transverse groove, which is impressed with a row of punctures.

Scutellum and elytra almost smooth, the membrane with four areole. Legs shortly pilose, the tibie with

scattered sete.

Length 33-43, breadth 12-23 millim. (¢ 9.)

Apparently the commonest species of the genus within our limits, and easily recog-

nizable by the almost smooth, shining, hairy upper surface, the clavus only being opaque,

and the comparatively stout, elongate antenne. SS. ductwosa, Stal, from California, the

type of which is before me, has the pronotum much less narrowed in front, the antenne

shorter and more slender, the corium entirely black, &c. S&S. andinus, Dist., from

Kcuador, is less elongate, and has the clavus shining, the elytra differently marked, &c.

4, Salda opacipennis, n. sp. (Tab. XX. fig. 5.)

Broad ovate, short, very shining, the elytra entirely opaque; the upper surface thickly clothed with long, erect,

blackish hairs, between which a very short, scattered, decumbent, golden pubescence is visible ; black, the

elytra with an elongate testaceous patch at the middle of the corium externally, a transverse pallid mark

towards the apex of the latter, and indications of some scattered whitish spots, the membrane fuscous,

with pale spots; the antenne blackish, with the basal joint obscure testaceous ; the rostrum, coxe, and

legs testaceous, the tibia and tarsi annulated with fuscous. Head smooth behind the ocelli, the latter

narrowly separated ; antenne comparatively short, extending very little beyond the hind angles of the

pronotum, slender, joint 2 one-half longer than 3, 3 and 4 equal in length. Pronotum almost smooth,

very short and broad, broadly explanate at the sides, rapidly narrowing forwards, the margins a little

rounded; anterior lobe deeply foveate in the middle and limited behind by a very deep transverse groove.

Scutellum and elytra almost smooth, the membrane with four areole. Legs pilose, the tibia with

scattered sete.

pronotum are broadly explanate from the base to the apex.

5. Salda comata, n. sp. (Tab. XX. fig. 6.)

Oblong-ovate, opaque, the vertex, pronotum, and scutellum slightly shining, the upper surface somewhat

thickly clothed with moderately long, semierect, blackish hairs, between which a short, fine, golden

pubescence is visible, the under surface with silvery pubescence; black, the head in front, the lateral

margins of the pronotum to near the apex, and a space in front of the anterior coxal cavities, flavous or

whitish, the elytra fuscous, the clavus with a pale streak at the apex, and the corium much variegated

with lighter colour, especially towards the sides, the membrane pale, with the nervures and some spots

in the areole fuscous; the antenne fuscous, with the first and second joints partly flavous; the legs

testaceous, the tibiae and tarsi usually more or less annulated with fuscous, the femora in one specimen

lined with black on the lower side. Head, pronotum, and scutellum very finely rugulose ; ocelli narrowly

separated ; antenne pubescent and sparsely pilose, moderately long, slender, joint 2 one-half longer

than 3, 3 and 4 equal in length; pronotum moderately narrowed in front, narrowly explanate at the

sides, which are slightly rounded, the anterior lobe with a deep transverse depression in the middle, and

separated from the posterior lobe by a transverse groove. Elytra minutely punctured; membrane moderately

long, with four elongate areole. Legs pilose and pubescent, the tibize with scattered sete.

Length 4-43, breadth 2 millim. (3 9.)

Hab. Mexico, Pedregal (Bilimek, in Mus. Vind. Ces.).

There are several specimens of this species in the Vienna Museum, mostly in very

bad condition. It is the only hairy Central-American Salda known to me that has the

A single female specimen from Guatemala seems to belong to this common holarctic

species. It has the upper surface somewhat thickly clothed with very short golden

pubescence, and the pronotum is perhaps a little more narrowed in front than in the

European examples before me. It is unnecessary to quote the full synonymy here, for

which see Dr. Reuter’s work 3.

7. Salda tropicalis, n. sp. (Tab. XX. fig. 7.)

Ovate, slightly shining, the upper surface clothed with a very short, fine, golden, and the under surface with

a silvery, pubescence ; black, the head flavous in front, the elytra with a short streak at the apex of the

clavus and numerous irregular markings on the corium, of which a long streak at the middle of the costal

margin and a shorter one before the apex are most conspicuous, testaceous or flavous; the membrane pale,

with the nervures, a spot on the costal margin, and some streaks in the areole fuscous or black; the

antenne with the base of the first joint and the apex of the second more or less testaceous; the legs

testaceous, the tibie and tarsi annulated with fuscous or black. Head, pronotum, and scutellum finely

rugulose; ocelli narrowly separated; antenne pubescent and sparsely pilose, moderately long, slender,

joint 3 one-half longer than 2, 3 and 4 equal in length; pronotum much narrowed in front, the lateral

margins narrowly explanate and slightly rounded, the anterior lobe with a deep transverse depression in

the middle, and separated from the posterior lobe by a deep transverse groove. Elytra minutely punctate ;

membrane moderately long, with four elongate areola. Legs shortly pilose, the tibize with strong sete.

Hab. Guatemata, San Gerénimo and Guatemala city (Champion); Panama, Volcan

de Chiriqui (Champion).

Seven examples. Very like S. saltatoria, but with the yellowish markings on the

elytra more extended and the pronotum a little less dilated at the sides in front, this

last-mentioned character separating it from S. pallipes (Fabr.). 8. tropicalis also

closely resembles S. opacula, Zett., but the costal margin of the corium in the latter

is uninterruptedly flavous from below the base almost to the apex. In 8S. humilis

(Say) the pronotum is more narrowed in front, with the sides straighter, and the elytra

are differently coloured.

8. Salda quadrimaculata, n. sp. (Tab. XX. fig. 8.)

Ovate, rather short, opaque, the upper surface clothed with a very short, fine, decumbent, golden pubescence ;

black, the elytra with two transverse flavous spots on the costal area, one below the base and the other

just before the apex, the membrane pale, with the nervures and one or two small spots in each areola

fuscous ; the antenne fuscous, with the base testaceous; the rostrum and legs testaceous, the tibize and

tarsi faintly annulated with fuscous. Head, pronotum, and scutellum rugulose; ocelli narrowly separated ;

antenne short, slender, finely pubescent, joint 3 a little longer than 2 (4 broken off); pronotum greatly

narrowed in front, not dilated at the sides, the anterior lobe raised on the disc and depressed in the centre.

Membrane moderately developed, with four long areole. Legs finely pubescent, the tibize with fine

scattered seta. .

Length 23, breadth 14 millim. (9.)

Hab. Panama, Pefia Blanca 3000 feet (Champion).

Two examples. In this minute species the pronotum is not dilated at the sides, and

much narrowed in front, and the elytra have two well-defined flavous spots on the

costal area, characters separating it from all the other Central-American forms. From

the N.-American and Antillean S. humilis (Say) it may be known by the differently

coloured elytra, the distinctly separated ocelli, and its less elongate shape.

broad ring on the apical joint, favous or testaceous, the second joint (as in the type) sometimes obscure

testaceous ; the venter varying in colour from almost entirely black to flavous with a large black patch

on each side of the sixth segment at the base ; the pleura with one or two flavous spots near each of the

coxal cavities ; the rostrum and legs flavo-testaceous, the tarsi and the apices of the tibie: annulated with

greatly narrowed in front, the sides rapidly and obliquely converging from the base forwards and very

narrowly explanate, the anterior lobe occupying almost the entire width, transversely depressed in the

middle in front, and separated from the posterior lobe by a very deep transverse groove. Membrane

nearly as long as the comparatively short corium, with four long areole. Legs finely pubescent, the tibie

with short, fine, scattered sete.

Stal’s type of S. ventralis, now before me, is in a mutilated condition, and without

an apical joint to the antenne. ‘The five specimens examined from Central America,

from which the above description is taken, agree very well with it, except that they

have the yellow marks more extended on the corium. ‘There is no trace of maculation

on the membrane, the nervures being simply darker. Stal! describes the insect as

glabrous, but this is a mistake.

area of the corium to about the middle and a patch at its apex, each partly or entirely enclosing a spot

of the ground-colour, a minute spot at the inner apical angle of the corium and another on its disc, and a

faint streak at the base of the clavus and a spot at its apex, flavous or whitish; the membrane pale, with

the nervures and some faint spots fuscous; the antenne fuscous, with the basal joint testaceous; the

venter flavous, with a large black patch on each side of the sixth segment at the base; the rostrum, coxe,

spots near each of the coxal cavities. Head, pronotum, and scutellum distinctly rugulose ; ocelli narrowly

separated; antenne finely pubescent, slender, moderately long, joints 2-4 subequal in length ; pronotum

moderately narrowed in front, the sides obliquely converging forwards and narrowly but conspicuously

explanate, the anterior lobe transversely depressed in the middle in front and separated from the posterior

lobe by a deep transverse groove. Membrane much shorter than the corium, with four long areole.

A widely distributed genus, of which four species* have been described from

America, one of them being from within our limits, whence three others are now added.

They have very much the general facies of Salda. The Central-American forms differ

from the Palearctic P. marginatus, Latr., as well as from the North-American

P. americanus, Uhler, in having the pronotum much narrowed in front. The flavescent

markings at the sides of the pronotum show the extent of the expanded semitransparent

margins. ‘The tarsi are 2-, 2-, 3-jointed, the basal joint of each being very short. The

males have the seventh ventral segment split down the middle, leaving the terminal

genital segment exposed, and they are very apt to be mistaken for the opposite sex f.

Dr. Bergroth (Bull. Soc. Ent. Fr. 1890, pp. xvi, cxix) has revived Latreille’s first name for

this genus, though the author himself changed it, presumably to avoid confusion with his

earlier Ochthera (Diptera, 1802 {). These insects live upon the sandy banks of streams,

(type in mus. nostr.).— ANTILLES, Cuba 3, Grenada ®, St. Vincent 4.

The type of this insect was obtained by us from the Sallé collection. It is

easily separable from the other Central-American species of the genus by the acute

anterior angles of the pronotum, and by the series of well-defined ochreous spots

along the costal margin of the corium; the ochreous lateral spots on the pronotum

are small, triangular in shape, and placed a little behind the anterior angles. The face

is sometimes obsoletely carinate between the eyes. The rostrum is black at the base.

The four specimens seen from Mexico are all females, measuring from 5-6 millim. in

length and 3-34 millim. in width. The Grenada examples in the British Museum

have a ferruginous patch on each side of the pronotum behind the ochreous spot.

A specimen from Vera Cruz is figured.

. Broad ovate, black; the head from the ocelli forwards more or less shining and eeneous in colour, the rest of the

surface opaque; the pronotum with the sides rather broadly, except at the lateral angles, and the basal

margin in the middle, the corium usually with from two to four small spots on the outer margin, as well as

the outer edge, and often a spot near the inner apical angle, and some marks on the pleura, ochreous; the

head, pronotum, and scutellum with the usual irregular bluish-grey markings; the rostrum broadly black

at the base, for the rest ochreous; the legs ochreous, in some specimens slightly infuscate; the upper

surface with very minute scattered golden scales, the under surface with a bluish-grey pruinosity, the

elytra more or less ferruginous. The ochreous lateral patches on the pronotum often

have a short dark marginal streak. Differs from P. perbosci (which also is without a

well-defined carina between the eyes) in the rounded anterior angles of the pronotum,

the larger ochreous patches at its sides, the less distinctly spotted margins of the elytra,

and the smaller size; and from the Palearctic P. marginatus, Laty., in the anteriorly

narrowed pronotum, the narrower head, the non-carinate face, the black labrum, &c.

3. Pelogonus viridifrons, n. sp. (Tab. XX. fig. 14, ¢.)

Broad ovate, black; the head from the ocelli forwards shining and of a brilliant metallic-green colour, the rest

of the surface opaque ; the labrum and antenne, the sides of the pronotum narrowly, except at the lateral

angles, the outer margin of the corium, the rostrum, some marks on the pleura, and the coxa, ochreous,

the basal margin of the pronotum and the claval suture inclining to ferruginous, the pronotum, scutellum,

and elytra also with some irregular bluish-grey markings ; the legs infuscate, with the base of the femora

ochreous, in one specimen almost entirely ochreous; the upper surface with very minute scattered golden

scales, the under surface with a bluish-grey pruinosity, the abdomen and legs with a bluish-white

pubescence. Face densely, irregularly rugulose, carinate between the eyes ; the latter large, very prominent

in the male, less so in the female. Pronotum, scutellum, and elytra sparsely, distinctly punctate;

pronotum short, nearly twice as wide at the base as at the apex, the sides somewhat rounded and rapidly

converging from the base, the anterior angles completely effaced, the lateral angles subacute and projecting

a little beyond the elytra; elytra widening to near the middle; nervures of the membrane indistinct.

This well-known genus, the original name for which is, unfortunately, preoccupied

in Zoology *, includes various American species. The identification of the Central-

American forms has been made from a series of specimens kindly communicated for

comparison by M. Montandon, whose monograph of the genus will shortly be published.

He recognizes eight species as distinct, six of which occur within our limits, whereas

Stél placed all the published names under two only—G. oculatus (Fabr.) and G. nebu-

losus, Guér. As M. Montandon possesses a much more varied material, which will be

fully described in his forthcoming Monograph, the main characters only of each species

are very briefly noted here. The synonymy is given on his authority. In the males

the terminal genital segments are asymmetric. In the females the sixth ventral

segment is more or less convex along the middle. The antenne (Tab. XX. fig. 17)

have their third joint very short and small, and completely connate with the fourth.

These insects, which have much the appearance of small Batrachians, live gregariously

on the sandy banks of streams, and they also have the power of leaping with facility.

Of this species we possess about a dozen examples, agreeing with the types

communicated by M. Montandon. It is nearly allied to G. oculatus (Fabr.), but differs

from that insect in having the pronotum broadly rounded at the sides and feebly sinuate

Found in numbers by myself in Guatemala. In this insect the sides of the pronotum

are straight and obliquely converging from the prominent, rounded lateral angles. The

markings are very variable, specimens occasionally occurring with the pronotum broadly

bordered with ochreous at the. sides (fig. 16), or with the basal margin of that colour.

This very widely distributed species, described by Prof. Uhler ® as “a variously tinted

chunk of insect entity,” appears to be the commonest member of the genus. It has

the pronotum much less constricted at the sides than in G. variegatus ; the lateral

angles are rounded, moderately dilated, and finely crenulate. The general coloration

is very variable, specimens (from Texas) occasionally occurring with the sides of the

pronotum very broadly and the basal half of the elytra whitish.

the base of the pronotum as nearly straight, whereas in our insect it is strongly

M. Montandon has sent us for examination numerous specimens of this insect from

lateral angles of the pronotum more oblique in front (instead of subtransverse) and less

coarsely crenate. The pronotum is strongly constricted at the sides behind the anterior

angles, the margins being subparallel in front. The general coloration is usually more

obscure than in G. variegatus. G. vicinus is the only species of the genus found by

myself at elevations above 2500 feet on the slope of the Volcan de Chiriqui.

four occurring within our limits. In the imaginal form the short anterior tarsi* are

furnished with a simple strong claw only, the true basal joint being completely fused

with the tibia, but in the nymph (as in the Australian genus Matinus, Stal) two long

claws are present. The terminal genital ventral segments of the male, as in Gelastocoris

(Galgulus), are asymmetric. The antenne are 4-jointed+; the third joint is narrow,

barely one-third the length of the fourth, and almost connate with it. ‘These insects

live in muddy places on the banks of ponds and streams, and are usually coated with

an earthy incrustation, which cannot be easily removed.

A common insect within our limits. Differs chiefly from M. nepeformis in the genital

structure: in the male the last segment is small and placed considerably to the left of

the longitudinal axis of the body, and the preceding ventral segment is foveate on the

right side near the margin; in the female (fig. 21 a) the two triangular pieces forming

the last segment are broader than long, and the sixth segment is not very deeply

emarginate. Four females, from Presidio and Amula, differ from the rest in having

the genital segment (fig. 210) very short; three of them were sent with males and

females of MV. fuscipes from Presidio. We figure a clean female specimen from

Guatemala, also some of the details of structure.

The nymph (fig. 23) has been found at Bugaba and Caché, with the imaginal form.

It has (as noted above) two long claws to the anterior tarsi; the joints of the inter-

mediate and hind tarsi are fused into one; the third and fourth antennal joints are

connate; and the ocelli are absent.

_ According to Montandon5 this species is. fairly abundant from Costa Rica south-

wards to the Argentine Republic, and more southern in its distribution than M. fuscipes.

Two females from Purula and Guatemala city seem to belong here: they both have

the two triangular pieces forming the terminal genital segment greatly developed,

and the preceding ventral segment very deeply emarginate. In the specimen from

Guatemala city (found in company with both sexes of MV. fuscipes) the sixth ventral

segment (as in a female before me from Colombia) is much swollen at the sides

anteriorly. The male has the last genital segment broad, and the preceding segment

is not foveate on the right side. Our figures of the genital segments are taken from

Fam, NAUCORIDZ.

This is the last family dealt with by Stal in the fifth part of his ‘ Enumeratio Hemi-

pterorum,’ published in 1876. During recent years very many American species have

been described by Montandon, chiefly from material contained in the Stockholm, Vienna,

Paris, and Hamburg Museums, as well as from a certain number in his own collection.

We possess, unfortunately, very few Naucoride from Central America, nine species

only being represented in our collection. Various types, however, have been lent us,

so that we are enabled to figure most of the known forms. The sexual characters are

important in some cases, as in Pelocoris, these insects having the terminal abdominal

segments very differently formed in the two sexes. None of the Naucoride, so far as

I am aware, carry their eggs about on their backs, a common habit with many of the

Belostomide. Some of the species live in stagnant, others in running water.

Subfam. CRYPHOCRICIN A.

CRY PHOCRICUS.

Cryptocricus, Stal, Enum. Hemipt. v. pp. 141, 143; Montandon, Verh. zool.-bot. Ges. Wien, 1897,

pp. 6, 7.

The type of this genus, C. barozzi, Sign., from Brazil *, is a brachypterous insect,

with very peculiarly formed abdominal segments in the male. C. macrocephalus, if

correctly identified by me, differs in many respects, and should probably form the type

of a new genus, when the male is discovered. In the form of the legs it approaches

the Belostomide.

Cryphocricus macrocephalus, Mont. Bull. Mus. Paris, 1897, p. 124 ‘

Hab. Mexico, Cuernavaca in Morelos (H. H. Smith); Guatemata, Alta Vera Paz

Of this curious species we have received a single female example from Mexico. ‘The

type appears to be of the same sex.

AMBRYSUS.

Ambrysus, Stal, Stett. ent. Zeit. 1862, p. 459; Hemipt. Afric. iii. p. 174; Enum. Hemipt. v.

pp. 141, 143 ; Montandon, Verh. zool.-bot. Ges: Wien, 1897, pp. 6, 11; Bull. Mus. Paris,

1897, pp. 129, 130.

An American genus, including eighteen described species, no fewer than ten of

which are from within our limits. Five only are represented in our collection, and

three of these by single specimens. The sexual characters are similar to those of

Limnocoris. Ambrysus is nearly allied to that genus, from which it chiefly differs in

having the interocular portion of the head narrowing forwards (instead of backwards),

and in the absence of the meso- and metasternal elevations, the various species no

doubt living in more stagnant waters. ‘The pronotum is deeply excavate in front for

the reception of the head in both Amérysus and Limnocoris, a character separating

these genera at once from Pelocoris. Naucoris profunda, Say *, the type of which was

taken by Bennett in Mexico, probably belongs to this genus (and not to Limnocoris,

as supposed by Stal); it cannot be identified with certainty from the description.

Montandon has fully tabulated all the species of Ambrysus in the above-quoted papers.

1. Ambrysus geayi.

Ambrysus geayi, Mont. Bull. Mus. Paris, 1897, pp. 128, 130°.

Hab. Panama, Darien (Geay, in Mus. Paris.1).

This species is a close ally of A. oblongulus, from which it is stated to differ in having

the posterior angles of the pronotum more truncated and the anterior angles more

acute, the posterior angles of the connexival segments more produced, the scutellum

dark at the apex, &c.

2, Ambrysus oblongulus. (Tab. XXI. fig. 3, 3.)

Ambrysus oblongulus, Mont. Verh. zool.-bot. Ges. Wien, 1897, pp. 11, 14°.

356 HEMIPTERA-HETEROPTERA.

In this insect the head is very deeply sunk into the pronotum, the margins of the

latter are faintly crenulated (when seen under a strong lens), and the surface of

the head and pronotum is finely and densely granulated. The type, communicated

by Dr Aurivillius,is a female. The two specimens (¢ and 9 ) found by myself on the

Island of Taboga are a little smaller. The posterior angles of tie connexival segments

3-5 are acute in both sexes. The body is much flattened, as in A. geayi.

3. Ambrysus pulchellius. (Tab. XXI. figg. 4,4; 4a, antenna.)

Ambrysus pulchellus, Mont. Verh. zool.-bot. Ges. Wien, 1897, pp. 11, 16°.

Hab. GuatemMata (Mus. Hamburg.1), Paso Antonio, San Gerdénimo, Guatemala city

(Champion).

Of this species we possess six specimens, including both sexes. ‘The males differ

from the females in having the posterior angles of the fourth and fifth connexival

segments more acute and somewhat produced. These examples differ from the

description in having a few fine scattered punctures towards the anterior angles of

the pronotum, and the disc slightly depressed and finely, transversely wrinkled.

From A. pudicus, Stal, it may be known by its more oblong shape and the much

broader head.

Ambrysus parviceps, Mont. Verh. zool.-bot. Ges. Wien, 1897, pp. 12, 17°.

Hab. Mexico (Mus. Vind. Ces.', Saldé).

We have a single example of this species, a female, like the type, which is now

before me. Both have some scattered rather coarse punctures on the pronotum

towards the sides and the disc transversely wrinkled in the centre in front.

A. parviceps differs from A. pudicus in the relatively narrower interocular portion

of the head, the rounded and more dilated sides of the pronotum, and the acuminately

produced posterior angles of the connexival segments. The type is figured.

The type is figured. Distinguishable by its oblong, somewhat parallel shape

(approaching A. oblongulus in this respect), large size, and dark coloration, the

posterior angles of the fifth connexival segment only produced.

7. Ambrysus mexicanus. (Tab. XXI. fig. 8, 2.)

Ambrysus mexicanus, Mont. Verh. zool.-bot. Ges. Wien, 1897, pp. 18, 21°.

Hab. Mexico (Boucard, in Mus. Holm.'; Bilimek, in Mus. Vind. Ces.*).

Very like A. guttatipennis, but smaller, smoother, and more narrowed forwards, the

embolium less dilated, the posterior angles of the connexival segments less produced.

Our figure is taken from one of the types belonging to the Stockholm Museum.

8. Ambrysus hybridus. (Tab. XXI. fig. 9, ¢.)

Ambrysus hybrida, Mout. Verh. zool.-bot. Ges. Wien, 1897, pp. 18, 22°.

Hab. Mexico (Mus. Vind. Ces. & coll. Montandon'), Jalapa (Hége).

The type of this species belonging to the Vienna Museum is a male, and we possess

a female agreeing with it. The posterior angles of the connexival segments are acute

and slightly produced (the fifth being rather prominent) in the male, and pointed in

the female. In the nearly-allied A. guttatipennis the angles are more acuminate.

Notwithstanding the difference in colonr (the greenish tint usually changing to brown

after death), it is not improbable that Say’s unidentified Naucoris profunda =

A. hybridus, Mont.: Bennett collected between Vera Cruz and Jalapa, whence Hoge

has sent us a specimen of A. hybridus. .

This is the largest of the Central-American species of the genus, and easily distin-

guishable by the two flavous spots on the corium—one at the middle of the apical

margin, the other opposite the inner apical angle of the embolium,—the embolium

being, as usual, flavous to near the apex. ‘The type, a female, is figured.

We have a single male example of this insect from Mexico (Sallé), without definite

locality. It is easily recognizable by its peculiar coloration. ‘The posterior angles of

the connexival segments 2-5 are acutely produced. Prof. Uhler® states that this

species is to be found in the best-watered parts of Arizona and Mexico, dwelling in

the quiet waters adjacent to streams and in standing pools, especially such as are

grassy. .

This American genus includes eighteen described species, four of which are from

within our limits, whence one other is now added, the remainder being from South

America. In the males the fifth ventral segment is freely movable, it being divided

longitudinally into three pieces, and two genital segments are visible. In the females

the fifth ventral segment is entire and one genital segment only is visible. In the new

species described below, L. insularis, the eyes are not margined at their outer angle

and the suture between the clavus and corium is very indistinct. ‘The meso- and

metasternal caring, as noted by Montandon, are concave and flexible at the summit, so

as to enable the insects to cling to stones, &c., in the rapid streams, and they differ in

form according to the species. The species of Zimnocoris are fully tabulated by

Montandon in the above-quoted papers.

Hab. Mexico (Sallé, in Mus. Holm.; Mus. Vind. Ces.1).

Of this species I have seen a male belonging to the Stockholm Museum, which is

here figured, and a female from the Vienna Museum ; the last-mentioned specimen is

very dirty and discoloured. ‘The posterior angles of the connexival segments 2—4 are

not produced, a character distinguishing this insect at once from Z. stali.

3. Limnocoris inornatus. (Tab. XXI. fig. 14, 2.)

Limnocoris inornatus, Mont. Verh. zool.-bot. Ges. Wien, 1898, pp. 417, 423°.

Hab, GuaTEMALAa (Mus. Hamburg.!), Paso Antonio (Champion).

The single female example referred to this species, from the “ tierra caliente” of the

Pacific slope, differs from the description in having the clavus and corium irregularly

mottled with darker colour, and the connexival segments 3-5 broadly bordered with

fuscous in front. ‘The posterior angles of the fifth segment only are acute. The

lateral portions of the metasternum are faintly transversely wrinkled. The type was

probably discoloured. J. inornatus is very like L. signoreti, but it is smaller and

smoother; the pronotum is scarcely depressed behind the transverse groove, more

rounded at the sides, and less narrowed in front; the embolium is more strongly

sinuate at the sides posteriorly ; and the mesosternal ridge is differently formed.

Hab. Costa Rica, Buenos Aires (Pittier, in coll. Montandon').

The type of this peculiar species, a male, has been kindly lent by M. Montandon for

figuring. The insect is green above, and rounded in outline, with acute posterior

angles to the pronotum, the eyes broadly margined at the outer angle, the margins

of the elytra deeply sinuate, and the suture between the clavus and corium indistinct.

The elytra are without membrane, and there is no trace of wings visible.

5. Limnocoris insularis, n. sp. (Tab. XXI. fig. 16, 2.)

Broad oval, opaque, the basal portion of the pronotum and the elytra pale sordid yellow, dotted with fuscous ;

the rest of the pronotum, the head, and scutellum sordid ochreous, the membrane fuscous; the underside

and legs flavous, the metasternum and abdomen darker. Head broad, with the eyes almost half the width

360 HEMIPTERA-HETEROPTERA.

of the pronotum, about as long as the width of the interocular space at the base, somewhat rounded and

abruptly declivous in front, closely, almost imperceptibly, punctate, very faintly transversely grooved on

each side just within the anterior margin, the eyes gradually converging posteriorly and not margined

behind at the outer angle. Pronotum very short, along the median line slightly longer than the head,

about one-third narrower in front than behind, the sides much rounded and converging from a little

before the base forwards, the anterior angles rather sharp, the hind angles broadly rounded; the usual

transverse groove very faintly indicated laterally, the space behind this not depressed and closely

impressed with minute fuscous punctures; the anterior portion of the surface sculptured like that of the

head, the disc transversely wrinkled in front, the lateral portions with scattered, rather coarse punctures.

Scutellum punctured, the apical portion transversely wrinkled. Elytra with the clavus and corium

densely impressed with fine fuscous punctures, the embolium more coarsely and more sparsely punctate ;

embolium limited inwards by a distinct ridge, the external border strongly rounded, and somewhat

abruptly sinuate behind the middle; the suture between the clavus and corium scarcely distinguishable ;

the claval suture a little more than one-half the length of the scutellum; membrane well developed.

Connexival segments not acuminate at: the posterior angles. Mesosternal carina acute, deeply notched

towards the anterior end, abruptly widened behind and with a rounded, concave space at the top, in the

centre of which is a raised point. Metasternal carina oval, sulcate down the middle, and extending

forward as a thin plate between the intermediate coxe. Abdomen with an acute ridge on the second

ventral segment extending forward between the hind coxe.

Length 6, breadth 4 millim. (9.)

Hab. Honpuras, Bonacca I. (Gaumer).

One specimen. Belongs to Montandon’s section EE of the genus, near ZL. inornatus.

It has the suture between the clavus and corium very indistinct, and the eyes are not

margined behind at their outer angle. The pronotum is more rounded at the lateral

angles than in L. pallescens (Stal).

PELOCORIS.

Pelocoris, Stal, Enum. Hemipt. v. pp. 142, 144 (1876).

This genus, a close ally of Llyocoris and Naucoris, includes about a dozen described

species, all American, three of which have been recorded from within our limits, one

only extending north of Mexico. The three Central-American forms are all found on

the Isthmus of Darien.

A common species within our limits, and varying from 9-113 millim. in length. It

is quite unrecognizable from Palisot de Beauvois’s figure. There are specimens of it

from North America in the British Museum, and also others from the Island of

Grenada determined by Prof. Uhler. Most of the Central-American examples belong

to the var. d7impressus, which has a darker scutellum and a dark streak on the

embolium ; the two forms were found in company at Paso Antonio. The male has the

fifth and following abdominal segments freely movable, the fifth being attached to the

fourth in the centre only; the fifth and sixth ventral segments are each separated

into three pieces, the convex central portion being divided from the lateral pieces by a

suture on each side. The long genital segment is divided into two in this sex only.

The fourth and fifth connexival segments are more acutely produced at the posterior

angles in the male than in the female. An antenna is figured on our Plate (fig. 17 d).

marked with brown.

Fam, BELOSTOMIDA.

This family includes the largest known forms of Heteroptera, and it is well repre-

sented in America, both in the tropical and temperate regions. The Belostomide, as

a whole, were not dealt with by Stal, but they have been monographed by Mayr

BIOL. CENTR.-AMER., Rhynch., Vol. II., January 1901. 46

362 HEMIPTERA-HETEROPTERA.

[Verh. zool.-bot. Ges. Wien, xxi. pp. 899-440 (1871)], who, however, does not figure

any of them in that work. The species of Deinostoma (Serphus), Pedinocoris, Zaitha,

Abedus, Belostoma, &c., carry their eggs about on their backs, glued together in a large

flat mass on the elytra, and, according to Miss F. W. Slater (Amer. Nat. 1899, pp. 931-

933), this operation is performed by the males only, the females compelling them to

undertake the task. |

Many of these insects have been attracted to light in large numbers, and the

North-American species of Belostoma and Benacus appear to be known in the

United States under the name of “electric light bugs.” In Kingsley’s ‘Standard

Natural History,’ ii. pp. 255-261 (1884), Prof. Uhler has given an excellent account

of the characters and habits of the North-American Belostomide, as well as of

those of the Naucoride, &c. In addition to the species enumerated here, two others

have been recorded from Mexico, but further evidence is required before they can be

included in our list: these are Hydrocyrius columbia, Spin. (cf. Mayr, Verh. zool.-bot.

Ges. Wien, xxi. p. 429), and Belostoma griseum, Say (cf. Walk. Cat. Heteropt.

Deinostoma, Kirkaldy, Entom. 1897, p. 258.

This genus is a very close ally of Pedinocorts and Abedus, differing from the former

in having the metasternum keeled, and from the latter by the 3-jointed antenne and the

entirely pubescent ventral surface of the abdomen. ‘The females of all these genera

have two small, shallow, piligerous fovee * immediately before the apex of the sixth

ventral segment, which is slightly truncate or feebly emarginate in this sex. ‘The

males have the corresponding segment rounded at the apex and without fovee.

Abedus, Stal, Steti. ent. Zeit. 1862, p. 461; Mayr, Verh. zool.-bot. Ges, Wien, xxi. pp. 400, 403

(1871).

The known species of this genus all inhabit Central America, one of them extending

northward into the Southern United States. Four have been described, this number

being here reduced to three. A. signoreti is a common insect within our limits. The

metasternum is keeled, as in Deinostoma. The antenne are 4-jointed, the second and

third very short, and each furnished with a long process, the third and fourth being

sometimes fused into one. Montandon [Bull. Soc. Bucarest, ix. nos. 2 and 3, p. 11

(1900)] treats Serphus and Pedinocoris as synonymous with Adedus, chiefly on account

of the great similarity in general facies of the species of each of these genera and

the difficulty in making out their antennal structure; but for the present it seems

preferable to retain them as distinct.

Caché (Rogers); Panama, Volcan de Chiriqui (Champion).

With types of A. signoreti and A. vicinus before me, I am unable to distinguish

more than one species. The slight differences mentioned by Mayr are probably

sexual *: in the male the lateral portions of the sixth ventral segment (as well as the

median) are longer than in the female, and this would account for the somewhat

different position of the spiracles.

The longer membrane (which varies a little in development and in the neuration)

and the more sparsely pilose median portion of the venter separate A. signoreti from

both the preceding species. The antennal processes are intermediate in length between

these of A. ovatus and A. breviceps.

The species of this genus, which is probably restricted to the New World, are very

closely allied and difficult to distinguish ; five occur within our limits. The females

have the sixth ventral segment more or less truncate at the apex and usually with two

small fascicles of hair at the tip. In the males the corresponding segment is rounded

or subacuminate at the apex.

The numerous specimens from Guatemala and Panama which are here referred to

Z. micantula are a little smaller than the only South-American specimen of that insect

before me. They measure from 11-13 millim. in length, and 53-64 millim. in breadth,

in this respect agreeing with the dimensions given by Mayr”. Z. métnuscula, Uhler,

seems to belong to the same species: it is described * as having “‘a purplish tint

over its olive-brown upper surface; the costal margin pale testaceous; the underside

of the body, together with the legs, testaceous, the latter variously banded with brown.”

Dr. Aurivillius informs me that there are specimens of Z. micantula, Stal, from

Honduras, in the Stockholm Museum. The present insect is much smaller than any

of the other Central-American members of the genus. It resembles Z. elliptica in

general shape, being considerably narrowed forwards; the head is shaped very much

as in Z. minor. ‘The number of membrane-nervures varies from 6—9 in specimens from

the same locality, showing that no reliance can be placed on one of the chief

characters (9 nervures, instead of 8) used by Buchanan-White to distinguish his

Z. zelotypus*, The South-American (Argentine) example (?) mentioned has the

abdomen more pointed at the tip, and the membrane a little more produced, than any

of our specimens.

having paid much attention to them. They divide up into two groups: one, including

N. mexicana and N. montezuma, with the carina on the fourth or fourth and fifth

ventral segments thickened and smooth, and the femora and trochanters vittate with

black or piceous beneath ; the other, including NV. shooter’, N. undulata, and NW. ameri-

cana, with the ventral carina acute and hidden by the swimming-hairs, and the femora

and trochanters immaculate beneath.

A very variable and common insect in’ Central America. It is easily distinguishable

by the very large eyes, which are narrowly separated behind, the blackish vitta on the

underside of the femora and trochanters, and the smooth and thickened median carina

of the fourth ventral segment. The females have this segment elongate, the apex of

the sixth produced into a long process in the middle, and the apex of the fifth also

slightly produced in the centre. The males have an additional ventral segment *, the

fourth not longer than the sixth, and the seventh narrowly produced and subtruncate

at the tip. The specimens from Jalapa (with one exception) and all those from

Guatemala southwards have the anterior angles of the pronotum more or less

rounded, instead of acute and slightly deflexed, as in the type; but as intermediate

forms occur, very little value can be placed on this character. The females, it may be

noted, often have the sides of the pronotum more sinuous than the males. Mr. Rogers

sent us a large number of specimens of this species from Costa Rica.

One of the types of WV. klugii, Fieb., belonging to the Berlin Museum, has been

examined. We give figures of the ventral segments of both sexes—6 b(¢),7(2);

also of the genitalia of the male, opened (6 ¢), and of the antenna (6 @).

Hab. Mexico f (Coffin, in Mus. Oxon.').

Very like WV. mexicana, and agreeing with it in having a dark vitta on the underside

of the intermediate and posterior femora and trochanters, but differing from that insect

in its much more elongate shape; the eyes also are a little smaller and less convex,

the interocular space is more deeply sulcate laterally on the vertex, the ventral carina

in both sexes is smooth and thickened down the entire length of the fourth and fifth

segments, and there is a smooth space down the centre of the following segment.

None of these last-inentioned characters are noticed in the description’. The types,

g @, have been examined. The North-American WV. insulata, Kirby, said by

Prof. Uhler to occur in Mexico, and of which I have seen a specimen determined by

Mr. Kirkaldy, is a nearly allied form, with the posterior femora and trochanters also

vittate beneath ; but it differs from 1. montezuma in having the eyes less approximate

behind and the ventral carina thickened along the fourth segment only.

* Apart from the visible convex genital segment.

+ Prof. Poulton informs me that the locality is not ‘“* W. Mexico,” as stated, the “‘ W” on the label simply

indicating that it was a Westwood specimen.

This appears to be the most widely distributed of the American Notonecte, and

Prof. Uhler considers that NW. americana, Fabr., and NV. variabilis, Fieb., are probably

conspecific with it. The insects here referred to V. undulata, most of which are from

Yucatan, are smaller and narrower than any of the other Central-American forms

known to me, and they have the anterior half of the pronotum so closely rugulose as

to appear subopaque ; the eyes are flattened, and scarcely more distant behind than in

N. mexicana; the fourth ventral segment is acutely keeled down the middle; the

elytra have an oblique, pale stramineous, humeral patch, sometimes so extended as to

leave the apex only of the corium black; the femora and trochanters are immaculate

beneath. It is unnecessary to quote the full synonymy here.

NV. undulata in having the eyes more widely separated behind, and flatter, the anterior

lobe of the pronotum smoother. With such a limited amount of material, no opinion

can be expressed as to its validity as a species. The distribution quoted 2, like that of

N. variabilis, is far too disconnected to be real.

This genus seems to be quite as well represented as Notonecta within our limits,

five species being here enumerated. These are very nearly allied, and they can,

indeed, be separated only by the pronotal structure of the males, this sex being always

distinguishable by the angularly dilated lower edge of the basal portion of the anterior

tibia. The antenne are 3-jointed (Fieber describes them as 4-jointed, counting the

minute basal portion of the third as a true joint), the genus thus differing from

Notonecta, in which they are 4-jointed; the posterior tarsi are without claws, as in

Notonecta (Fieber states that there are two claws to all the tarsi). ‘The intermediate

femora are received into long deep grooves in the mesosternum, while in Notonecta

they are free. The ventral carina in the females is not depressed towards the apex,

but continued as a prominent ridge to a little beyond the tip of the abdomen, where it

terminates in a projecting point: in the males it is depressed and interrupted towards

the apex and there becomes much less prominent. All the Central-American forms

have the anterior tarsi 2-jointed in both sexes, the vertex not produced in the male,

the pronotum and elytra quite smooth and subhyaline, the coloration of the dorsal

surface of the body showing through. As in Notonecta, little or no value can be

attached to the coloration of the upper surface for specific separation.

Of the American species described by Fieber, I have been able to identify only one,

and the others are here treated as new. ‘The insects known to North-American

entomologists as A. platycnemis appear to have been wrongly identified.

ef the upper surface rufo-testaceous or testaceous ; the under surface, antenne, and legs testaceous, the

venter black, the terminal segment and some spots on the connexivum excepted, the posterior femora

beneath, and sometimes the anterior and intermediate tibia externally, each with a dark streak down

the middle. Head (with the large eyes) nearly as wide as the pronotum in the male, a little narrower

in the female; interocular space not quite twice as wide on the vertex as at the base, considerably

narrowed beneath, the vertex sulcate down the middle. Pronotum about as long as the scutellum in the

male, slightly shorter in the female; the disc in the male with two broad elongate depressions towards

the middle and a very large subtriangular depression on each side, these latter almost enclosing an oblique

oval elevation behind, the spaces between the depressions appearing raised and forming three longitudinal

ridges. Legs stout, the four anterior tibie much widened, the anterior pair in the male angularly

Sixteen specimens are referred to this species. It is the largest and most robust of

the Central-American forms. The males have the head, with the large eyes, nearly

as wide as the pronotum, the latter with four deep depressions on the disc, the spaces

between these forming longitudinal ridges. The legs are stout, the four anterior

tibiee broad, the anterior pair much widened in the male. This insect must be very

nearly allied to A. macrophthalmus, Fieb., from Haiti, and A. femoralis, Fieb., from

Puerto Rico; but without specimens from those localities before me for comparison,

it would not be safe to identify it with either of them*. It is probable that the

North-American and Mexican insects referred by Prof. Ubler! to A. platycnemis,

Fieb., really belong here, as well as his Anisops sp.? from Lower California [Proc.

the eyes) nearly as wide as the pronotum in the male, a little narrower in the female; interocular space

narrow, becoming very narrow behind and here sometimes obsoletely carinate in the male, shallowly

sulcate on the vertex. Pronotum short, about as long as the scutellum in the male, shorter in the

female; the disc in the male with two deep elongate depressions towards the middle and a very large,

deep, subtriangular depression on each side, these Jattcr almost enclosing an oblique oval elevation behind,

the spaces between the depressions appearing raised and forming three longitudinal ridges. Legs rather

slender; the anterior tibia in the male angularly dilated on the lower edge at the base, and also

considerably widened.

St. Vincent 4.

This is the commonest Anisops within our limits, and it has been found in plenty

in the Pearl Islands by myself and by Mr. Gaumer in Yucatan. The specimens from

Bugaba vary a good deal in size, and they are also blacker than the others; some of

the females, too, from David (found with the ordinary males) have the pronotum very

short, but all seem to belong to one variable species. The red spots at the humeral

angles of the elytra, and those on the disc of the pronotum of the male, are evanescent.

The pronotal structure separates it from all the other Central-American species, except

A. carinatus, which is a larger and much more robust insect, and has the eyes less

approximate. The male has larger eyes and deeper lateral depressions on the pronotum

than the same sex of A. aldidus. One of the types, a male, of A. platycnemis, Fieb.,

belonging to the Berlin Museum, has been examined, and there seems to be no reason

for treating this as distinct from the Antillean A. pallipes (Fabr.). A. elegans, Fieb.,

from “ America,” to judge from a drawing of the type, and its small size, probably

belongs to the same species.

3. Anisops albidus, n. sp. (Tab. XXII. fig. 14, ¢.)

Elongate, narrow, rather slender, smooth, shining ; sordid white, the scutellum more or less rufo-testaceous,

the legs, antennae, and under surface pale testaceous; the abdomen above testaceous, with transverse

black bands, beneath black, with the median carina and some marks on the connexival segments pale

testaceous. Head (with the eyes) narrower than the pronotum in both sexes; interocular space about

twice as wide on the vertex as at the base, the vertex sulcate down the middle. Pronotum (along the

median line) about as long as the scutellum ; the disc in the male with two elongate deep depressions

towards the middle and a very large subtriangular shallow depression on each side, thus appearing

tricarinate in this sex. Legs rather slender; the anterior tibiw in the male angularly dilated on the

lower edge at the base, and also considerably widened.

Length 63, breadth 13 millim. (¢ 9.)

Hab. Nortu America, Texas.—MExico, Presidio de Mazatlan (forrer).

Six examples have been received from Mr. Forrer, two of which are nymphs.

Very like A. pallens, but comparatively more elongate, the scutellum shorter, the

pronotum with four deep depressions on the disc in the male. The coloration of

the scutellum is perhaps variable, though similar in the five full-grown specimens

seen. The interocular space is narrower in the male than in the female, this being

especially noticeable beneath, the insect differing in this respect from A. pallens.

There is a specimen ( 2 ) of this species from Texas in the British Museum, sent by

Prof. Riley under the name of A. platycnemis.

4. Anisops crassipes, n. sp. (Tab. XXII. fig. 15, ¢.)

Elongate, moderately robust, very shining ; nigro-violaceous, the head and a triangular patch at the sides of

the pronotum in front sordid white, the elytra with several small, triangular, carmine-red spots at the

humeral angles; the abdomen black, testaceous towards the base above, the connexival segments each

with a flavous spot beneath, the rest of the under surface in great part, the antenne, and legs testaceous,

all the tibia externally, and the hind femora beneath, each with a more or less distinct darker median

line. Head with (the eyes) nearly as wide as the pronotum in the male, a little narrower in the female;

interocular space about twice as wide on the vertex as at the base, the vertex sulcate down the middle.

Pronotum almost unimpressed and similarly formed in both sexes, a little shorter than the scutellum.

Legs comparatively stout ; the anterior tibie in the male angularly dilated on their lower edge at the

base, and also greatly widened.

Length 7-73, breadth 2-23 millim. (¢ 2.)

Hab. Guatemata, San Gerénimo, Duefias, Guatemala city (Champion).

Five specimens. Distinguishable by its very dark coloration, the rufous spots at

the humeral angles of the elytra, the stout legs, and the almost unimpressed pronotum

in both sexes. The anterior tibiz are greatly widened in the male.

5. Anisops pallens, n. sp. (Tab. XXII. fig. 16, ¢.)

Elongate, rather slender, smooth, shining; testaceous or pale testaceous, the head and pronotum whitish, the

abdomen partly black above and almost entirely so beneath, the flavous spots on the connexival segments

excepted. Head (with the eyes) a little narrower than the pronotum ; interocular space about twice as

wide on the vertex as at the base, the vertex deeply sulcate down the middle. Pronotum unimpressed

and similarly formed in both sexes, much shorter than the scutellum. Legs rather slender, but with the

anterior and intermediate tarsi comparatively stout ; the anterior tibie in the male angularly dilated on

their lower edge at the base, and also considerably widened.

A. pallens agrees with A. crassipes in having the pronotum unimpressed in both sexes,

but differs from that species in its smaller size, much shorter pronotum, pallid colora-

tion, and more slender limbs. The colour of the abdomen and metanotum is, as usual,

visible through the diaphanous elytra.

Of this genus we have, unfortunately, very little material, not a single representative

having been obtained by us from Nicaragua or Panama. Many species must inhabit

the central plateau of Mexico, where, indeed, one is so exceedingly abundant as to

be collected and sold in large quantities for the food of cage-birds. Amongst the

Central-American forms before me, two well-marked groups or subgenera are repre-

sented, one with and the other without a claw to the anterior tarsi (pala).

In the males of most of the Corixe there is a curious stridulatory organ, termed the

strigil, on the right or left side of the upper surface of the abdomen towards the apex,

this varying in structure according to the species*; the abdominal segments, ventral

and dorsal, are also asymmetric in this sex, sometimes on the right side and sometimes

on the left f.

I have not seen a specimen of this species from within our limits. It is nearly as

large as the European C. geoffroyi, Leach. Prof. Uhler+ describes “ the pronotum as

having nine or ten narrow yellow lines; the clavus crossed by zigzag lines at the base,

and by others which become more slender and straight towards the tip; the corium

with similar lines, which are more sinuous and interrupted towards the inner margin.

The pale curved, a little widened in the middle, and acute at the tip; those of the

male cut off obliquely at the apex, and the sides not curved, but nearly parallel. The

frontal depression of the male oblong, not very deep, extending up to about as far as

the clavus, corium, and membrane closely marked with short, irregular, undulate, transverse, pale lines,

these becoming wider and quite straight on the basal portion of the clavus, the marginal area testaceous,

and the dorsal segments of the abdomen, sometimes partly black ; the legs entirely pale. Head with two

rows of punctures on the vertex and some punctures near the eyes; the frontal depression very large,

oval, deep. Pronotum obsoletely rastrate, not carinate. Elytra with the clavus very sparsely, obsoletely

rastrate, the corium very minutely punctulate. Anterior femora stout, subangularly dilated on the lower

side at about the middle; anterior tibiw broadly dilated, triangular, acutely produced at the outer apical

angle; pale broad, strongly rounded on their outer edge, blunt at the tip, with numerous long hairs on

the inner edge. Intermediate tibice about one-half longer than the tarsi, the tarsi a little shorter than the

claws. Ventral segments asymmetric on the left side. Strigil absent.

Several specimens of both sexes. Recognizable by the acutely triangularly dilated

anterior tibiz in the male, and the absence of a strigil in this sex. ‘The elytra are

closely and irregularly vermiculate with pale lines, these, however, becoming straight

towards the base of the clavus. C. cube, according to Guérin’s figure, has the anterior

tibiz not so acutely produced at the apex, and the pale more curved, in the male.

4, Corixa guatemalensis, n. sp. (Tab. XXII. figg. 19, 194, 4, 3.)

do. Rather short, comparatively broad, shining; the head flavous, the eyes black; the pronotum with about

seven black and seven obscure testaceous transverse lines, of almost equal width; the mesonotum black ;

the elytra nigro-fuscous, the clavus and corium only with obscure paler transverse lines, the marginal

area black, the membrane immaculate; the body beneath pale testaceous, the abdomen in great part

black ; the legs flavo-testaceous, the long hairs on the hind tarsi black. Head with two interrupted

rows of punctures on the vertex, and some other punctures near the eyes, and with a long, oval,

moderately broad, frontal depression. Pronotum obsoletely rastrate, not carinate. Elytra with the

clavus and the base of the corium finely rastrate. Anterior tibie broad, subtriangular ; pale moderately

broad, subparallel at the base, rounded on their outer edge towards the apex, the latter somewhat pointed.

Intermediate tibia much longer than the tarsi, the tarsi and claws subequal in length. Ventral segments

very asymmetric on the right side. Strigil on the left side, broader than long, with five rows of teeth.

Length 53-53 millim.

Hab. GuaTemata, near the city (Champion).

Six specimens. A small obscurely-coloured species, chiefly distinguishable by the

triangularly dilated anterior tibiz in the male, and the finely rastrate clavus. It is

smaller than C. kollari, the clavus is more distinctly rastrate, and the indistinct elytral

markings are much more regular.

d. Moderately elongate, rather slender, feebly shining ; pale testaceous, the eyes black; the pronotum with

seven narrow transverse black lines; the elytra with short, irregular, undulated, transverse black lines,

which are narrower than the pale interspaces, and become a little straighter on the basal portion of the

clavus, the marginal area immaculate ; the tips of the intermediate tarsi, and the apices of the hind tarsi

rather broadly, infuscate. Head broad, the interocular space at the base wider than one of the eyes, with

two rows of punctures on the vertex, and some other punctures at the sides, and with a very short

median carina at the base; the frontal depression large, oval, deep. Pronotum, clavus, and corium

subrastrate, the pronotum not carinate. Anterior tibia strongly produced at the apex, beneath which

is a short tooth, the pale appearing to be articulated at about the middle of their lower edge; the latter

very broad, somewhat piriform, rather blunt at the tip, and furnished with a row of long and very fine

hairs on their inner edge. Intermediate tihize more than one-half longer than the tarsi, the latter of

about the same length as the claws. Ventral segments asymmetric on the right side. Strigil ?

Length 4 millim.

Hab. Mexico, Tres Marias Is. (Forrer).

The description is taken from a single male. Two immature females, with equally

broad head, sent with it from the same locality, have the pronotum and elytra smoother,

the pronotum with ten (instead of seven) transverse black lines, and the lines crossing

the basal portion of the clavus quite straight; these specimens perhaps belong to a

different species, but till more material is obtained nothing can be done with them.

C. marie is one of three very small, nearly allied Mexican species, and distinguishable

from the other two by the shape of the anterior tibie and pale, and the broad head.

C. verticalis, C. pygmea, and C. burmeisteri, Fieb., and C. reticulata, Guér., appear to .

be very similar American forms.

6. Corixa parvula, n. sp. (Tab. XXII. figg. 21, 21a, ¢.)

3. Very like C. marie, the markings of the upper surface being nearly similar, the legs, the long hairs on

the hind tarsi excepted, entirely pale; the head not so wide, the interocular space at the base being

narrower than one of the eyes, and with a distinct smooth raised line down the middle of the whole

length of the vertex, terminating in a projecting point at the base, the frontal depression very large,

oval, and deep; the pronotum with nine black lines, the sides obliquely truncate ; the clavus and corium

smooth ; the anterior tibiew considerably produced at the apex, but without the apical tooth; the pale

short and very broad, somewhat piriform, slightly pointed at the tip, with a row of long fine hairs on

the inner edge; the intermediate claws longer than the tarsi. Ventral segments asymmetric on the

right side. Strigil ?

Length 4 millim.

Hab. Mexico, Presidio de Mazatlan (forrer).

One male. Very like C. marie, from the islands opposite, but with a narrower

head, shorter pale, entirely pale intermediate tarsi, and longer intermediate claws.

The North-American C. burmeisteri, Fieb., must be a very near ally of this insect, but,

to judge from Fieber’s figures, it has the pale of the male more pointed at the tip.

The pronotum has nine transverse black lines.

Prof. Uhler (P. Z. 8. 1894, p. 224) has referred to C. reticulata, Guér., some very

similar specimens from the Island of Grenada; these, however, have the marginal area

of the elytra partly infuscate. According to Guérin the pale of C. reticulata (tof ¢)

are obliquely obovate.

7. Corixa sexlineata, n. sp. (Tab. XXII. figg. 22, 22a, ¢.)

¢. Moderately elongate, rather slender, smooth, shining; pale testaceous, the eyes black; the pronotum

nigro-fuscous, with six narrow transverse yellow lines (these being narrower than the five dark

interspaces) ; the elytra nigro-fuscous, with short, narrow, undulate, transverse pale lines, these becoming

quite straight on the basal portion of the clavus, the marginal area with a spot towards the apex and the

. costa blackish ; the dorsal surface of the abdomen with two black spots in the middle; the apices of

the intermediate tarsi slightly infuscate ; the hind tarsi with long fuscous hairs. Head with two rows

of punctures on the vertex and some other punctures close to the eyes, and with a projecting point in the

centre at the base, the interocular space at the base much narrower than one of the eyes; the frontal

depression very large, oval. Pronotum not carinate. Anterior tibia strongly produced at the apex ;

pale broad and somewhat piriform, rather blunt at the tip. Intermediate tibie nearly one-half longer

than the tarsi, the latter not quite so long as the claws. Ventral segments asymmetric on the right

side. Strigil on the left side, transverse, with three rows of teeth.

Length 4 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith).

One specimen. Differs from the two preceding species, and also from the other

small American forms already alluded to, in having fewer transverse lines on the

pronotum. The eyes at the base, as seen from above, are one and a half times the

width of the interocular space. The pale markings on the elytra are narrower than in

C. marve or C. parvula.

for a broad space at the base (the part covering the motanotum), corium, and membrane closely marked

with short, undulate, irregular, transverse black lincs, the marginal area pale, with a black mark at the

apex and a faint transverse dark streak a little beyond the middle; the abdomen, and sometimes the

meso- and metanotnum also, partly black ; the legs entirely pale. Head with a short median carina at

the base, and with two interrupted series of punctures on the vertex and some other punctures near the

eyes ; the frontal depression very large, almost extending to the inner margin of the eyes, oval, moderately

deep. Pronotum with a conspicuous median carina in front. Elytra very minutely punctulate, deeply

sinuate at the sides before the middle of the marginal area. Anterior tibie stout; pale broad, spoon-

shaped, somewhat pointed at the tip, with a row of very long hairs on their inner edge. Intermediate

tibie nearly one-half longer than the tarsi, the tarsi a little shorter than the claws. Ventral segments

of the abdomen asymmetric on the left side. Strigil on the right side, oval, much Jonger than broad, with

six rows of teeth. Fifth dorsal segment: with a fringe of very long bristly hairs at the right outer angle,

The above description has been taken from a large number of specimens sent by

A. Dugés to the British Museum. C. mercenaria, as is well known, swarms in the

large lakes near the city of Mexico, and a great deal has been written about it from an

economic point of view. The eggs, larve, and imagines are collected and sold in Mexico

as articles of food, it is said for both man and birds, and of late years they have even

been imported into England for feeding cage-birds. Guérin* mentions two species,

C. mercenaria and C. femorata, as being sold in this way, and a third is now added, the

latter being a close ally of C. mercenaria. Thomas Gage, in 1625, appears to have

been the first traveller who noticed that these insects were used for food in Mexico,

and his observation has been confirmed by Say and others. Immense quantities of

them have been captured on the wing towards evening.

9. Corixa edulis, n. sp. (Tab. XXII. fig. 24, 3.)

3. Elongate, smooth and shining, flavo-testaceous, the eyes black; the pronotum with from 10-12 very

slender, transverse, black lines, which become fainter in front; the elytra with the clavus, except for a

broad space at the base (the part covering the metanotum), corium, and membrane closely marked with

short, transverse, undulate, irregular black lines, the markings so arranged as to form four irregular

longitudinal series on each elytron, the marginal area pale, with a transverse streak beyond the middle

and the apex slightly infuscate; the abdomen in great part testaceous; the legs entirely pale. Head

with indications of a short median carina at the base, and with two interrupted rows of punctures on the

vertex and some punctures near the eyes; the frontal depression very large, broad oval, moderately deep.

Pronotum without carina. Elytra very minutely punctulate, moderately sinuate at the sides below the

base. Anterior tibiee stout; pale spoon-shaped, produced and somewhat pointed at the tip. Intermediate

tibia much longer than the tarsi. Ventral segments asymmetric on the left side. Strigil on the right side,

oval, mnch longer than broad, with four rows of teeth. Fifth dorsal segment with a fringe of short hairs

at the right outer angle.

Length 7? millim.

Hab. Mexico, Lake of Texcoco (Dugeés, in Mus. Brit.).

Three males only have been seen of this species, two of them without heads, and

one female in a bad state of preservation. Nearly allied to C. mercenaria, but more

elongate, the pronotum without a carina in front, the elytral markings arranged in

irregular longitudinal series, the pale and strigil differently formed. As in C. merce-

naria, the elytra have a broad immaculate space at the base of the clavus. ‘This last-

mentioned character-will separate the present species from C. inscripta.

the eyes. Pronotum not carinate, very faintly and interruptedly rastrate. Elytra moderately sinuate

at the sides below the base; the clavus and corium finely rastrate, the clavus becoming smoother in front.

Anterior femora very stout; pala long and narrow, much curved on their outer edge, furnished with very

long hairs within, and with a long curved claw at the apex. Intermediate femora with a fringe of

very long hairs beneath, the tibie and tarsi subequal in length, the claws shorter than the tarsi.

g. Head with a shallow longitudinal depression in the middle beneath, and with several deep punctures near

the lower angle of the eyes; anterior femora strongly, angularly dilated on the iower side towards the

base ; the pale formed as in the female. Strigil on the right side, small, longer than broad, with four rows

of teeth, the third row shorter than the others. Ventral segments asymmetric on the left side.

Length 93-10 millim.

382 HEMIPTERA-HETEROPTERA.

Hab. North America, Upper? and Lower California’, Texas?. — Mexico??§

(Bennett | 2), Oaxaca (Sallé ).

Var. The black markings on the underside of the head more extended, the transverse flavescent lines on the

clavus and corium narrower, the clavus with (¢) or without (9) a pale lunate mark at the apex, the

mesonotum and the marginal area of the elytra almost entirely black, the black markings on the legs more

extended, especially on the intermediate tibis.

Hab. GUATEMALA, near the city (Champion).

It is impossible to identify C. abdominalis, Say, or C. femorata, Guér., for certain, in

the absence of the types, which are probably lost, but the descriptions seem to apply

to the specimens before me. Say, it is true, does not mention the pale lunate mark at

the apex of the corium, but this is absent in the two females from Guatemala, and in

one of those of the same sex from Mexico. The only character given by Guérin for

C. femorata’ 8 is the stout anterior femora in the male. The species is a very distinct

one, on account of the presence of a long curved claw to the front tarsi, and the angular

dilatation of the very stout anterior femora in the male. The Guatemalan specimens

merely differ from the others in their darker coloration. ‘The strigil of the male of

each form has been examined. Prof. Uhler treats? C. abdominalis and C. bimaculata

as synonymous. A Guatemalan specimen is figured.

13. Corixa unguiculata, n.sp. (ab. XXIL. figg. 26, 26a, b, ¢.)

3. Moderately elongate, shining; pale testaceous, the eyes black; the pronotum with 8 or 9 transverse black

lines, which are of about the same width as the pale interspaces; the elytra nigro-fuscous, crossed by

interrupted, undulated pale lines, these becoming rather broad and straight at the base of the clavus, and

more irregular on the membrane, the marginal area testaceous, black in the middle and at the apex; the

body above and beneath partly black: the intermediate legs with the knees and the apices of the tarsi,

and the apical joint of the hind tarsi, blackish. Head faintly carinate at the base, with an interrupted

row of coarse punctures on either side of the vertex, each terminating in a deep fovea beneath, and a row

of finer punctures close to the eyes; the frontal depression somewhat octagonal, very large and shallow,

about as broad as long, extending upward to a little before the inner angle of the eyes. Pronotum

obsoletely rastrate, smoother behind, with a faint indication of a short median ridge in front. Elytra

with the clavus and the basal half of the corium obsoletely rastrate, for the rest smooth. Anterior

femora very stout ; anterior tibie not dilated; palve long and narrow, much curved, and furnished with a

long claw at the tip. Intermediate tibize and tarsi subequal in length, the claws a little shorter than the

tarsi. Ventral segments asymmetric on the left side. Strigil ?

Q. Head without frontal depression; anterior tibia and pal# as in the male.

Length 8 millim.

Hab. Mexico, Oaxaca (Sallé, in Mus. Brit.); Costa Rica (Biolley, in coll. Distant),

Trazu (Rogers).

Five specimens. This insect agrees with C. abdominalis in having a claw to the

anterior tarsi; but it is much smaller; the male has a very large frontal depression,

which is truncated above and preceded by two deep fovew only (these foveee being also

present in the female), and the anterior femora are not angulate in this sex. The

pale and anterior tibiz are similarly formed in both sexes. It cannot be referred to

CORIXA.—-TENAGOBIA. 383

C. melanogaster, no mention being made of the anterior tarsal claw in the description

of that species.

TENAGOBIA.

Tenagobia, Bergroth, Ent. Monthly Mag. xxxv. p. 282 (1899).

This genus includes the American forms previously referred to Micronecta, Kirk.

(Sigara, auct.), from which it differs in the short lunuliform pronotum and the large

scutellum. Seven species have been recorded from Brazil and one from Venezuela,

one of the former extending to Central America, California, and the Antillean Island

of Grenada,

A variable species, as noted by Buchanan-White.

Notz.—Messrs. H. Pittier and P. Biolley have published a small pamphlet on the

Hemiptera-Heteroptera of Costa Rica (San José, 1895), based mainly on Mr. Distant’s

work in the ‘ Biologia Centrali-America.’ A few species of Reduviide, &c., however,

have been noticed by them, but it is probable that some of these have been incorrectly

identified. The following are not recorded from Costa Rica in the preceding pages :—

Apiomerus elatus, A. pictipes, and A. spissipes, Leogorrus venator, Homalocoris maculi-

collis, Rasahus hamatus, Repipta taurus, Sinea raptoria, Spiniger limbatus, and Limno-

coris profundus; and three species are not included in our list, viz., Macrocephalus

cimicoides, Swed., Agriocoris fulvipes, Fabr., and Heza acantharis, Linn.

Prof. Uhler (P. Z. 8S. 1894, pp. 198, 219) has incidentally recorded two species from

Central America or Mexico that have not been enumerated in the present volume,

viz., Schizoptera flavipes, Reut. (Ceratombide), and Microvelia marginata, Uhler; it

is possible that there has been some mistake about the Central-American habitat of

these insects, no definite locality being mentioned for either of them. He also states

(Kingsley’s Stand. Nat. Hist. ii. p. 277) that Stenolemus spiniventris occurs in Arizona

and Cuba, as well as in Mexico (cf. anted, p. 164).

384 HEMIPTERA-HETEROPTERA.

ADDITIONS To VoL. I. since 1893.

Mr. Distant (Trans. Ent. Soc. Lond. 1900, pp. 687-693) has noted a few additions

to Vol. I. of this subject, concluded by him in 1893. They are mentioned here solely

for the purpose of including them in the general Index to the two volumes of the

Rhynchota-Heteroptera.
