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.

BIOLOGIA CENTRALI-AMERICANA. 


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) ;

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

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.

PHATNOMA. 
Phatnoma, Fieber, Ent. Monogr. pp. 30, 57 (1844) ; Stal, Enum. Hemipt. iii. p. 117. 

The type of this genus is P. laciniata, Fieb., from the ‘‘ Kast Indies.” 

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 
area limited within and without by a sharply raised carina, each bearing a single row of oblong areole,

with transverse raised lines, the costal area closely reticulated, with three or more rows of small areolz, 
which are more or less hyaline ; wings extending beyond the abdomen; legs slender. 


In the allied genus Cantacader (= Taphrostethus, Fieb.) the pronotum is produced 
behind so as to completely cover the scutellum, and has five carine, and the elytra 
have an indistinctly defined clavus and a well-defined subcostal nervure, of which latter 
there is no trace in Phatnoma. 


Pronotum with more or less broadly dilated margins, the outer carinz on the 
disc parallel or subparallel; elytra suboval, the costal area extending 
broadly to the apex, without a series of larger areolz along the margin. 
Pronotal margins broad ; costal area with four rows of areolz at the middle. marmorata, n. sp.

Brownish-ochreous or sepia-brown, mottled with fuscous, the fuscous markings on the costal area of the elytra 
forming numerous vague transverse fasciz, which sometimes terminate in a smail black spot on the costal 
and inner margins, the apex of the clavus and some spots on the carine also black; the pronotal and 
elytral margins partly hyaline; the antenne testaceous, with the apical joint partly or entirely black, the 
third joint sometimes infuscate ; the legs testaceous, with the knees usually infuscate, the femora with a 
yellow annulus before the apex. Pronotum with the margins raised, and broadly, acutely dilated before 
the middle as well as in front, becoming narrow behind, the anterior dilatation terminating in a rather 
long slender spine ; the disc closely punctured and tricarinate, the outer caring subparallel. Elytra mode- 
rately broad, suboval, broadly rounded at the apex; discoidal and subcostal areas equal in width, separated 

_ by asharply raised carina, which extends forwards to the base, the discoidal area open behind and limited 
inwards by a curved carina which extends to near the tip of the elytra; the clavus and the sutural, 
discoidal, and subcostal areas with very small rounded punctiform areole, the discoidal and subcostal areas 
each with about five transverse or oblique pallid raised lines; costal area rather broad throughout, closely 
reticulated, there being four rows of areole at the middle, increasing to five or six behind.

before the apex. Pronotum with the margins greatly raised, and very broadly and obliquely dilated 
forwards, angularly produced in front and also at the sides anteriorly, the anterior dilatation terminating 
in a short spine, the margin rounded behind the outer angle; the disc closely punctured and tricarinate, 
the outer carine parallel. Elytra moderately broad, suboval, broadly rounded at the apex; discoidal 
and subcostal areas separated by a sharply raised carina which extends fowards to the base, the discoidal 
area limited inwards by a curved carina which extends to near the tip of the elytra; the clavus and 
the sutural, discoidal, and subcostal areas with very small rounded punctiform areole, the discoidal and 
subcostal areas each with about five transverse or oblique pallid raised lines; costal area broad to the tip, 
closely reticulated, there being five rows of areole at the middle, increasing to six or seven behind. 

Length 33-4, breadth 1,%—2,, millim. 


Hab. Mexico, Frontera in Tabasco (H. H. Smith); Guatemata, Cahabon in Vera 
Paz, San Isidro (Champion); Panama, Volcan de Chiriqui (Champion). 


Five specimens. Very like P. marmorata, but with the margins of the pronotum 
still more broadly dilated and extending obliquely forwards (the pronotum appearing 
deeply emarginate in front), the costal area of the elytra broader and with an additional 
row of small areole. A specimen from Chiriqui is figured. 


3. Phatnoma ovata, n.sp. (Tab. I. figg. 3; 3a, the body beneath, ? .) 


Lighter or darker brownish-ochreous, the outer carine of the pronotum and the costal margin and carine of the 
elytra spotted with black or fuscous, the inner basa] margin of the clavus also blackish ; the small areole 
of the pronotal and elytral margins hyaline; the legs and antenne testaceous, the apical joint of the 
latter black at the tip. Pronotum with the margins a little raised, angularly dilated before the midde as 
well as in front, becoming narrow behind, the anterior dilatation terminating in a short spine; the disc 
closely punctured, tricarinate, the outer carine curved inwards in front. Elytra rather short, regularly 
oval, somewhat narrowly rounded at the apex ; discoidal and subcostal areas equal in width, separated by 
a sharply-raised carina which extends forwards to the base, the discoidal area limited inwards by a mode- 
rately raised carina which extends to the apex of the subcostal area, both areas with several transverse or 
oblique raised lines, and, like the clavus and sutura]l area, with very small rounded areole; costal area 
moderately broad, becoming narrow at the tip, with a row of oblong areole along the margin and three 
rows of much smaller areole within. 

Length 33-34, breadth 14-2 millim. 


Hab. Guatemata, San Isidro, Panajachel, Zapote, Capetillo, Dueias (Champion). 


Numerous examples, all from the Pacific slope. Differs from P. marmorata and 
P. annulipes in having the margins of the pronotum much less dilated, the outer 
pronotal carine not parallel, and the elytra regularly oval, with narrower costal area 
and a row of larger oblong areole along the margin.

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). 


One example. 


MEGALOCYSTA, n. gen. 


Rostrum extending to the first ventral suture, or to a little beyond it. Rostral groove parallel behind the 
front cox, uninterrupted, closed in front, the sternal lamin moderately prominent, the buccal lamine 
long and very prominent. Antenne distant at the base, inserted in deep cavities, long and slender, 
joint 1 stout, nearly twice as long as 2, 2 very short, 3 very elongate, obliquely truncate at the apex, 
4 much longer than 1 and 2 united, articulated to the preceding on the lower side just before the apex, 
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 
externally ; subcostal area narrow; costal area moderately broad; median nervure prominent and

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.

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.

slopes. The types of St&l and Walker have been examined; the latter is mutilated 
(as noted by Walker himself), the pronotal hood, &c. being broken off. We figure

(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

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

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. | 
Length 31, breadth 13 millim, 


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 
slightly raised, and does not reach the middle, it being quite short in L. vesiculosa ; 
the subcostal area (costal of Stal) is sometimes very narrow, with one or two rows of 
areole only, and sometimes nearly as broad as the discoidal, with three or four rows 
(as described by Stal) of closely packed small areole ; the membranous costal area has 
two or more series of areole. ‘The rostral groove is uninterrupted. The rostrum 
extends to the meso-metasternal suture in most of the species, sometimes shorter 
(L. longipennis) or longer (L. tenuis). The wings do not extend beyond the abdomen 
in any of the specimens examined. 


a. Antenne with joint 1 five times as long as 2. Pronotum with the 
membranous margins greatly dilated, vertical, and shell-like, the 
median carina strongly foliaceous, the hood large; elytra long and

the latter (except at the extreme base) black; the nervures of the pronotal processes and also the margins, 
the nervures of the elytra, and the costa to beyond the middle, minutely denticulate and pilose. Head 
without spines ; antenne finely pilose, very elongate and slender, joint 1 fully five times as long as 2 and 
much shorter than 4, 2 very short, 3 one-half longer than 4, Pronotum with the membranous margins

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 
appendages of about equal size, all of which are rounded at the summit.

denticulate. Head with five slender spines; antenne slightly pilose, slender and very elongate, joint 1 
about four times as long as 2, 2 very short, 4 much longer than 1. Pronotum with the membranous 
margins moderately wide, recurved, converging anteriorly, with two rows of areole; hood rather short, 
oval, considerably raised; the long median carina moderately foliaceous, becoming lower in front, with a 
single row of transverse areole, the outer carinse feebly foliaceous. Elytra long, widening from the base,

elongate, more closely reticulated, there being an additional row of areole in the costal 


area, the costal margin not ciliate (perhaps abraded); the antenne longer and paler. 
The general shape is elongate-triangular.

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,

Three examples. This insect resembles the European Tingis pyri in the form of the 
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

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

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.

the antenne testaceous, with the basal joint to near the tip, and the apical joint entirely, black, the second 
joint sometimes infuscate ; the legs testaceous, with the apical joint of the tarsi black. Head with three 
long slender spines—one median and two lateral; antenne long and slender, joint 1 about three and 
one-half times the length of 2, 2 very short, 1 and 4 subequal in length. Pronotum with the mem-

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.

tured. Elytra very long and narrow, gradually widening from the base, rounded at the tip; discoidal 
area somewhat fusiform, rather short, closely reticulated ; subcostal area very long and narrow, biseriate ; 
costal area with two rows of areole; the areole in the apical part of the sutural area very unequal in 
size, two of the inner ones being very large and pentagonal. Legs very long and slender. 
Length 3, breadth 1} millim. 


Hab. Guatema.a, San Gerénimo (Champion). 


One example. A small, narrow, elongate species, the elytra gradually widening 
from the base; the costal area with two rows of areolw, the nervures fuscous along the 
suture and towards the apex. 


11. Leptostyla tenuis, n. sp. (Tab. I. figg. 25; 254, profile; 256, part of 
the body beneath.) 


Elongate, very narrow ; body black, the integument whitish and hyaline; the elytra usually with a small spot 
ou the discoidal area behind, and the nervures in the apical third, testaceous; the antenne testaceous, 
with the basal (except at the tip) and apical joints black ; the legs testaceous, the apical joint of the tarsi 
infuscate. Head with five long slender spines; antenne long and slender, joint 1 about three times as 
long as 2 and shorter than 4, 2 very short. Pronotum with the membranous margins moderately wide, 
recurved, converging from the base forwards, forming a rather prominent angle in front, and with two 
rows of areole ; hood short and small, somewhat compressed, angularly projecting over the base of the 
head; the three carine feebly foliaceous, the interspaces closely punctured; the posterior triangular 
portion membranous. Elytra long and narrow, when closed not or scarcely wider than the pronotum, 
rounded at the tip; discoidal area long and subfusiform, nearly reaching the middle, closely reticulated ; 
subcostal area very long and narrow, biseriate throughout; costal area with two rows of areole to the 
base ; the areole in the apical part of the sutural area very unequal in size. Rostrum nearly reaching 
the end of the metasternum. 

Length 23, breadth 1 millim. 


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 
a narrow oblique fascia extending from the median nervure beyond the middle to the apex, widening 
outwards, a small spot on the discoidal area behind, and a narrow curved streak on the subcostal area, 
nigro-fuscous ; the nervures of the pronotal hood fuscous; the antenns testaceous, the basal joint infus- 
cate, except at the tip (the apical joint broken off); the legs testaceous, the tips of the tarsi infuscate. 
Head with two very short, slender, converging frontal spines; antenne long and slender, joint 1 about 


LEPTOSTYLA. 19 


two and a half times the length of 2, 2 very short. Pronotum with the membranous margins very 
broadly and arcuately dilated, recurved, widest at the middle, and with four rows of areol at this part, 
the areole small; hood short, oval, considerably raised; the three carinw feebly foliaceous, the inter- 
spaces closely punctured. Elytra gradually, arcuately widened from the base, the costal margin slightly 
hollowed at the middle, the apex rounded ; discoidal area not reaching the middle, subfusiform, closely 
reticulated ; subcostal area nearly as wide as the discoidal, triseriate; costal area with four rows of 
areole at the middle, diminishing to two at the base, the areole (like those in the sutural area) 
moderately large and not differing very much in size. 
Length 23, breadth 14 millim. 


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. 


13. Leptostyla bifasciata, n. sp. (Tab. II. figg. 3; 3a, profile.) 


Moderately elongate, broad ; body black, the integument testaceous and partly hyaline; the elytra with an 
oblique fascia before the middle, the apex (the large areolw excepted), and the space between the costal 
area and the inner margin thence to the base, fuscous or brownish, a spot on the discoidal area behind 
and the nervures on the dark portions of the elytra black ; the nervures of the hood and margins of the 
pronotum fuscous; the antenne testaceous (the apical joint broken off); the legs testaceous, the tarsi 
black. Head with a single slender frontal spine and two other shorter spines beneath it, the latter 
approximating at the tip; antenne long and slender, joint 1 about two and a half times as long as 2, 
2 very short. Pronotum with the membranous margins broadly and arcuately dilated, recurved, with two 
rows of moderately large areole ; hood rather large, broad-oval; the three carine feebly foliaceous, the 
interspaces somewhat sparsely punctate. Elytra moderately long, strongly, arcuately widening from the 
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 
testaceous, with the apical joint (except at the extreme base), and also the basal one, black; the legs 
testaceous. Head with two short slender frontal spines, approximating at the tip; antenne long and 
slender, joint 1 two and a half times as long as 2 and much shorter than 4, 2 very short. Pronotum 
with the membranous margins moderately wide, recurved, converging anteriorly, with two rows of 
areole ; hood short, oval, considerably raised ; the three carinz feebly foliaceous, the interspaces closely 
punctured. Elytra moderately long, arcuately widened from the base, rounded at the tip, the costal 
margin slightly hollowed at the middle; discoidal area rather short, subfusiform, closely reticulated ; 
subcostal area nearly as wide as the discoidal, closely reticulated ; costal area with three or four rows of

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 
margin slightly hollowed at the middle; discoidal area rather short, not nearly reaching the middle, 
subfusiform, closely reticulated; subcostal area nearly as wide as the discoidal, closely reticulated ; 
costal area with three or four rows of areole at the middle and two or three 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 and 
pentagonal. 

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-

LEPTOSTYLA.—LEPTOPHARSA. 21 


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.

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 :— 

Discoidal area of the elytra with an adventitious nervure extending from 
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.

1. Leptobyrsa latipennis, n. sp. (Tab. II. figg. 13; 13a, profile.) 


Very broad, testaceous, the margins of the pronotum and the elytra pale testaceo-hyaline; the pronotum with 
the lateral margins and the carine, and the elytra with the entire margin and the nervures, closely set 
with long fine hairs; the antenne and legs also thickly pilose, the hairs on the antenne very long and 
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, 
2 very short, 3 nearly twice as long as 1. Pronotum with the membranous margins moderately wide, 
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, 
the costal area transversely creased and with about six rows of areole from the base to the middle.

One example only of this remarkable species has been obtained. It is much 
broader and more pilose than the type of the genus, L. steind, Stal, from Brazil (the 
type of which is before me), and has the discoidal area of the elytra very much more 
tumid, the areole of the costal area more numerous, the pronotal hood very small

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.

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.)

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

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 
nearly as long as the elytra. Legs rather stout, the tibia sinuous within. 

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.) 

Moderately elongate, narrow, dull; testaceous or brownish-ochraceous, mottled with black or fuscous, the 
body beneath and usually the bulbous processes of the pronotum blackish, the reticulation of the latter 
fuscous in pale specimens; the antenne ferrugineo-testaceous, with the apical joint black; the legs 
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 
carina indistinct between the bulbous processes. lytra closely reticulated; the discoidal area 
surrounded by prominent nervures ; subcostal area irregularly biseriate; costal area with the long areole 
separated by stout transverse nervures, which are usually in part black, the ante-apical constriction 
generally with a conspicuous black nervure. 

Length 31-34, breadth 14-1} millim. 

Hab. GuaTemata, Panima and Cahabon in Vera Paz (Champion); Panama, Bugaba,

Var. The pronotum with the bulbiform processes smaller, less inflated, and more widely separated on the disc, 
the median carina distinct throughout. (Fig. 2.)

enumerated by Stal. Amongst the many new forms here described there are some 
connecting the typical species (with uniseriate costal area) with the two included by 
Stal in Americia, the latter having more numerous areole in the costal area. These 
insects are narrow and elongate in shape; the head usually has five more or less 
distinct spines, and obtuse, somewhat prolonged, antenniferous tubercles ; the antennze 
are contiguous at the base, rugulose, in some species distinctly pilose, stout, with the 
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 
varies in length, and the rostral groove in shape, according to the species. The third 
joint of the antenne varies in length.

1. Teleonemia ochracea, n. sp. (Tab. III. fig. 3.) 

Elongate, opaque ; brownish-ochraceous, blackish beneath, the tarsi and the extreme apices of the tibie black, 
the third joint of the antenne fuscous at the tip (the fourth broken off); the pronotum and under surface 
clothed with a mealy pubescence. Head with short, porrect frontal spines; antenne moderately stout, 
joint 2 shorter than 1, 3 very elongate. Pronotum tricarinate, the median carina raised anteriorly and 
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 


TELEONEMIA. 37 


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 
(Champion). | 


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 
short indistinct frontal spine; antenne stout, moderately long, densely and distinctly pilose, joints 1 and 
2 subequal, 4 longer than 1 and 2 united. Pronotum tricarinate, the outer carine converging in front

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. 


5. Teleonemia atrata, n. sp. (Tab. III. fig. 7.) 


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, 
joint 2 slightly shorter than 1, 4 considerably longer than 1 and 2 united. Pronotum elongate, the 
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

and under surface clothed with a mealy pubescence. Head with short frontal spines, the upper median 
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 
apex; the antenne a little more slender. (Fig. 10.) 


Hab. Mexico, San Juan Bautista in Tabasco (Hége); GuatTemata, Tamahu in Vera

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

examples the elytra are frequently more or less constricted beyond the middle, and the 
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. 
Length 32-4, breadth 1-14 millim. (¢ 9.)

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 .) 


Moderately elongate, narrow, opaque; body black or piceous, the integument grey or brownish-grey, the 
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 
long and separated by stout transverse nervures. Intercoxal portion of the metasternum very broad, the 
rostral groove being abruptly and greatly widened behind, the rostrum extending to the meso-metasternal. 
suture. Terminal ventral segment in the female with along, stout, obliquely projecting tubercle on each side.

Hab. Panama, Bugaba (Champion).—Amazons (Bates, in Mus. Oxon.). 


One specimen from each locality. Very like Zingis triangularis, Blanch.= Americia 
albilatera, Stél*, from Chiquitos and Rio Janeiro, Stal’s type of which is before 
me; but differing from it in having the antenne longer and more slender, the pronotum 
with a more inflated hood, and the median carina subangularly raised on the disc and 
infuscate in the centre, the elytra less truncate at the apex, with the discoidal area. 
open behind and the membranous costal area much narrower, the latter more closely 
reticulated, the areole being quite small. 


* 81 does not appear to have seen the figure of Tingis triangularis, Blanch., as his type of 7. (Americia). 
albilatera agrees perfectly with it, The same remark applies to Tingis circumdata, Blanch., which =

Length 53, breadth of the pronotum 13, of the elytra 44 millim. 


Hab. Panama, Bugaba (Champion). 


One specimen only of this extraordinary insect was obtained. 

It differs from the South-American £. nobilis (Guér.) (=circumdata, Blanch.), 
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.

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

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

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,

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

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 


48 HEMIPTERA-HETEROPTERA. 


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 :—

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

(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.

Q. Moderately elongate, rather narrow; ochraceous, mottled with fuscous, the pronotum with a dark transverse 
fascia before the middle, widening inwards posteriorly, and extending for some distance backwards, 
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. 

Length 53; breadth of pronotum 2, of abdomen 33 millim.

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 ! 
(H. H. Smith: 3); Guaremaua!, Aceituno (Champion: 3 @ ). 


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.

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).

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.

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.

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.

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

the basal half of the pronotum and the base of the scutellum coarsely and closely, the rest of the scutellum 
and the corium finely, punctured. Antenne stout, joint 4 oblong-ovate, a little longer than 2 and 3

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.

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.

which are from the Palearctic or Nearctic regions. A single species only is known to 
me from Central America f. 


* Phimophorus, Bergr., appears to be a Reduviid. 

ft Dr. Bergroth has also recorded two other species of the genus from within our limits, but it is possible 
there is some mistake about the localities. They are as follows :—A. crenatus, Say, from Mexico (Wien. ent.

Stal’s genus. 


1. Calisius ferox, n. sp. (Tab. V. figg. 2, 2a, 2; 26, antenna.) 

Q. Ovate, rather broad, opaque, ochraceous or obscure testaceous, the pronotum mottled with fuscous; the 
scutellum blackish or fuscous, with six pallid oblong spots—an oblique one at the sides below the base, 
one on each side of the median carina about the middle, and one below this extending to the margin, these 
latter sometimes connected ; the connexivum ferruginous or fusco-ferruginous, each segment with the 
granules along the apical and inner margins ochraceous or fusco-testaceous and the other marginal 
prominences black ; the legs and antenne testaceous, the apical joint of the latter fuscous; the under 
surface ferrugineo-testaceous. Head punctulate and closely studded with short, pallid, blunt spines, the 
antenniferous processes acute and divergent, the post-ocular spines extending outwards to beyond the eyes, 
the latter small; the apical process broad, as long as the rest of the head, emarginate at the tip; antenne 
short, joints’ 1 and 2 equal, 3 longer and more slender than 2, 4 ovate, about as long as 3. Pronotum sinuate 
at the sides before the middle, the posterior portion arcuately dilated, the base bisinuate; the four carine, 
sides, and apex studded with stout blunt spines, the interspaces punctulate. Scutellum closely, rather 
coarsely punctate, the raised basal portion, margins, and median carina studded with stout blunt spines. 


CALISIUS.—CALISIOPSIS. 67 


Connexivum broad, punctulate ; each segment with a row of pallid granules along the apical and inner 
margins, and three prominent blunt teeth along the outer margin. The narrow space between the 
connexivum and scutellum set with five coarse pallid equidistant granules. Beneath closely, finely 
granulate. Rostrum very short, not nearly reaching the base of the head. 

Length 4, breadth 13 millim, 


Hab. Panama, Bugaba (Champion). 


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. 


1. Calisiopsis ampliceps, n. sp. (Tab. V. figg. 4,4a,92; 48, antenna.) - 

©. Rather broad, oval, opaque, testaceous or ochraceous, the apical process of the head, the pronotum, and 
the sides of the connexivum mottled with fuscous, the scutellum pale, with an oblong mark at the middle 
of the sides and the raised basal portion blackish or fuscous, the body beneath ferrugineo-testaceous; the 
antenne and legs testaceous, the femora sometimes infuscate in the middle. Head (with the eyes) nearly 
as wide as the front of the pronotum, closely punctured, the sides, base, and apical process studded with 
coarse pallid granules and with two short rows of similar granules in the middle in front, together forming 
a V-shaped prominence, the post-ocular teeth extending outwards as far as the eyes; antenne glabrous, 
the apical joint granulate. Pronotum arcuately dilated at the sides behind and narrowing forwards, the 
lateral margins denticulate from about the middle forwards and crenulate thence to the base, the four 
carinz formed by rows of coarse granules, the interspaces closely punctured and sometimes with other 
scattered granules. Scutellum closely punctured, the median carina and margins each with a row of 
granules, the raised basal portion also studded with coarse pallid granules. Connexivum rugulosely 
punctured ; the apical margin of each segment studded with coarse pallid granules, the lateral margin 
with about four short teeth. The under surface rugulose at the sides, smoother in the middle.

Of this remarkable genus three species are known, all Tropical American, one of 
them extending on to the Isthmus of Panama. Walker’s name appears to have been 
overlooked, partly through his quite erroneous description of the antenne and partly 
on account of his having wrongly referred the genus to the Tingitide.

Two males of this species were found by myself at Bugaba. The form of the 
connexivum readily distinguishes this insect from the two other known members of the 
genus—P. eximia, Hagl. (=arida, Walk., and pallida, Uhl.), and P. lanceolata (F.) ; 
P. eximia, moreover, has a transverse nervure at the middle of each of the segments of 
the connexivum, and in P. lanceolata these segments are truncate and unemarginate 
behind. Dr. Bergroth (loc. cit.) has figured a portion of the connexivum of each of 
the three species. Specimens of P. eximia and P. lanceolata are contained in the 
British Museum, 


| PROXIUS. 
Prowius, Stal, Enum. Hemipt. iii. pp. 139, 141 (1878). 


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.

quadrate, sinuate at the sides, with the angles of both lobes prominent ; the anterior lobe obliquely trun- 
cate on each side in front, concave at the sides, and nearly covered by raised callosities, these forming a 
' prominent median and two oblique ridges on the disc and some transverse or oblique ridges at the sides ; 
the posterior lobe with a prominent transverse bisinuate ridge on the disc, and with a laterally projecting 
raised margin along the outer part of the base. Scutellum with an oblique foliaceous ridge on each side 
of the disc, the two ridges meeting behind, and a callous lateral margin. Abdomen moderately long; the 
outer apical angles of. the connexival segments slightly projecting, becoming more prominent posteriorly,

Two specimens. Differs from the other Central-American species of the genus in 
the strongly wrinkled callosities of the head and pronotum,:the pronotum (viewed 
laterally) appearing to have four deep excavations in front and the post-ocular portions 
of the head a deep cavity. - 


2. Proxius personatus, n. sp. (Tab. V. figg. 6, 7, 2.) 

Fusco-ferruginous, in great part covered by a thick whitish, whitish-ochreous, or griseous incrustation ; the

filiform, nearly twice as long as 2, 4 a little longer than 2, pilose at the tip. Pronotum transversely 
subquadrate, sinuate at the sides; the anterior lobe obliquely truncate on each side in front, concave 
externally, and truncate on each side at the base, with the angles prominent, the incrustation moulded 
into an inflated anteriorly bilobed prominence on the middle of the disc ; the posterior lobe with a feebly 
raised transverse bisinuate ridge on the disc, and a laterally projecting raised margin along the outer 
part of the base. Scutellum with an oblong more or less inflated prominence in the centre, connected in

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. 


8. Proxius gypsatus. (Tab. V. figg. 8, ¢; 8a, antenna; 9, ¢, var.) 
Proxius gypsatus, Bergr. Ent. Monthly Mag. xxxiv. p. +e, 


Fusco-ferruginous, in great part covered by a thick whitish or whitish-ochreous incrustation ; the legs and 
antennee ferruginous, the membrane fuscous. Head with the post-ocular portions broadly, subangularly 
or acutely dilated to far beyond the eyes; the antenniferous processes spiniform and slightly divergent ; 
the apical lobes short; the callosities forming a raised elongate-triangular plate on the middle of the 
head, outside which is a groove for the reception of the antennez ; antenne short, joint I stout, reaching

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 
widening to about the middle and subparallel beyond ; the fifth segment with a projecting tooth on the

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.

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,

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.

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.

This genus includes a single species from the State of Panama. It is perhaps 
nearest allied to Hesus, from which it differs in the shape of the head, the relatively 
longer antenne and legs, the antenne with the first and third joints very elongate and 
the fourth joint short, the small eyes, the prominent neck-like constriction of the 
pronotum, the pronotum itself truncate at the base, the long genital segment in the 
male, &c.

3. Fuscous, opaque, the head, femora, and antenne more or less ferruginous, the antenne with the third 
joint black at the apex and the fourth black at the middle, the basal halves of the tibie flavo-testaceous ; 
the under surface, some rows of spots on the abdomen excepted, and the upper surface of the connexivum 
in part, coated with a thin whitish-ochraceous incrustation ; the short shaggy hairs on the head, pronotum, 
and apical margin of the abdomen, and the bristly hairs on the two basal joints of the antenne, as well 
as those on the femora, fulvous ; the raised portions of the scutellum and corium, and the apical margins 
of the connexival segments, also clothed with very short fulvous hairs. Head with a smooth bare oblong 
spot on each side between the eyes, the post-ocular portions moderately tumid, unarmed. Pronotum with 
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. 

a. Antenne with joint 1 nearly twice as long as 3; outer apical angles of 
the connexival segments angularly projecting in both sexes, that of the

Found in some numbers by myself in the “tierra caliente” of Chiriqui. In both 
sexes of this species the connexival segments are angularly dilated at their outer apical 
angles, the fifth being widened into a triangular plate. The males have the abdomen 
much narrower than the females and subparallel, with the apex abruptly truncate, the 
fifth segment dilated laterally into a very prominent triangular plate. The type ( @ ) 
has been communicated by Dr. Aurivillius.

‘I'wo males and two females from Chiriqui are referred to this species, the type ( ¢ ) 
of which is before me. The males have the abdomen subparallel, with the outer 
apical angles of each segment angularly dilated, the fifth widened into a triangular

females the abdomen is broader and rounded at the sides, with the fourth segment 
wider than the fifth. ‘The basal joint of the antenne is about as long as the head, and 
a little longer than tne third joint. The type is dirty and somewhat abraded, our 
specimens showing the coarse, short, curled hairs much more distinctly above and

@. Ovate, broad, nigro-fuscous, clothed with very short, coarse, matted, decumbent, rusty-brown hairs, which 
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.

Seven examples. Very like A. crispatus (2), but with a short basal joint to the 
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 
dilated laterally into a short lobe. A specimen from Bugaba is figured. 


APHLEBODERRHIS.

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 :—

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

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.

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

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.

NANNIUM. 
Nannium, Bergroth, Ent. Monthly Mag. xxxiv. p. (1898) (part.). 


Head transverse, with spiniform antenniferous processes and an apical feebly emarginate process about reaching 
the middle of the basal joint of the antenne, the post-ocular portions rounded or terminating laterally in 
a very short spine; antennee with joints 1 and 2 stout or moderately stout, granulate, 3 longer and more 
slender, 4 piriform and pilose at the tip; rostrum short, reaching the base of the head. Pronotum 
transverse, subtruncate at the base and apex, the base slightly emarginate in the middle; the antericr 
portion short, very much narrower than the posterior portion, depressed, with two tubercles on the disc 
and outwardly directed, projecting, lobiform anterior angles, the anterior margin with an oblique tooth 
on each side below; the posterior portion rounded at the sides anteriorly, and with an undulate transverse 
ridge on the disc. Scutellum triangular, carinate down the middle. Abdomen moderately long, 
subparallel or feebly rounded at the sides, the apical margins of the connexival segments somewhat 
prominent. Corium reaching as far as the middle or apex of the second segment, raised above the 
membrane, more or less arcuate-emarginate within, the apex obtuse, the median nervure prominent. 
Membrane with a few distinct nervures. Intermediate coxee more widely separated than the hind 
coxee ; intercoxal portion of the meso- and metasternum broadly flattened. Venter convex, the fifth 
segment unisinuate at the apex in the female, the spiracles placed near the lateral margin. Mesosternal 
orifice prominent, surrounded by a raised carina. Legs short, slender, the femora moderately stout

Two very small species are referred to this genus, which has the genera! facies of 
Pictinus ; but differs from it in having the corium more raised, longer, and emarginate 
within, the membrane with some regular raised nervures, the pronotum distinctly 
toothed on each side at the apex below, and with two prominent tubercles on the 
anterior portion, and a transverse undulate ridge on the posterior portion. The 
position of the spiracles, the more feeble neuration of the membrane, and the form 
of the pronotum separate it from Brachyrrhynchus. 

Dr. Bergroth bases this genus chiefly upon the position of the spiracles, and includes

under it, in addition to NV. parvum, two South-American species with a differently 
formed pronotum. ‘he above-mentioned characters are taken from N. dituberculatum

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

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. .

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.

One specimen. Very closely allied to C. squalidus, but apparently distinct from it. 
It has the head truncate behind, the post-ocular portions being subrectangular; the 
antenniferous processes rounded externally and terminating in a short blunt spine;

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.

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 
and Severin, fourteen are American, two only being from within our limits. Brachyr- 
rhynchus, however, proves to be well represented in Central America, nineteen species 
being known to me, fourteen of which are described as new. They have the pronotum 
(except in B. abdominalis) very feebly emarginate at the base, the third antennal joint

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. 
The Central-American species may be tabulated thus :—

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.

projecting hairs. 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, emarginate at the tip; the 
spiniform antenniferous processes acute, divergent; the post-ocular portions dilated laterally into an acute 
spine, which extends outwards to about as far as the eyes; antenne rather slender, with a stouter basal 
joint, joints 2 and 4 subequal in length, 3 longer than 1, 4 piriform. Pronotum feebly emarginate 
at the base, moderately sinuate at the sides, the margins crenulate; the anterior portion slightly 
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.

Hab. Guatema.a, Cerro Zunil (Champion). 


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.

granulate and clothed with a few extremely short, curled, ochraceous hairs. Head (exclusive of the apical 
process) transverse; the apical process broad, extending to a little beyond the middle of the first antennal 
joint, slightly emarginate at the tip; the spiniform antenniferous processes acute, divergent; the post- 
ocular portions dilated laterally into a long acute spine, which extends to considerably beyond the eyes : 
antenne rather slender, joints 2 and 4 subequal in length, 2 a little shorter than 1, 3 nearly one-half 
longer than 2 and much longer than 1, 4 subpiriform. Pronotum feebly emarginate at the base, 
moderately sinuate at the sides, the margins very distinctly crenulate ; the anterior portion dilated on 
each side anteriorly into a broad rounded lobe, the callosities each with a short ridge; the posterior

(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 
legs and antennew 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, 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 
-emarginate at the base, strongly sinuate at the sides, the margins serrulate or crenulate; the anterior 
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 
slightly hollowed at the sides and emarginate at the apex, leaving the first genital segment rather broadly 
exposed, the latter with two broad, rounded, prominent lobes; in the male with the fifth segment

subparallel and the sixth obliquely narrowing, the latter produced into an obtuse lobe behind. Terminal 
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.

Hab. Mexico (Mus. Vind. Ces.: 2), Misantla (fF. D. Godman: 9°); Guatemata, San 
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. 


BRACHYRRHYNCHUS. 101 


The form of the pronotum approaches that of B. /eviventris and B. constrictus, except 
that the rounded anterior lobes are not dilated forwards. ‘The insect is unknown to

conspicuously granulate and very finely pubescent. Head subquadrate; the apical process stout, slightly 
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., 
and the exposed portion of the first genital segment is narrower. 


13. Brachyrrhynchus rugiventris, n. sp. 

3. Oblong, broad, pitchy-black, the venter, legs, and antenne piceous, the tarsi ferruginous, the membrane

eyes; antenne with joint 1 short and moderately stout, 2 shorter and more slender (3 and 4 broken off). 
Pronotum feebly emarginate at the base, strongly constricted at the sides, the margins crenulate ; the 
anterior portion rounded at the sides and with four short ridges on the disc; the posterior portion very 
much wider, rounded at the sides anteriorly and subparallel behind. Scutellum with an indistinct median

One specimen. In its somewhat parallel shape this insect resembles the males of 


102 HEMIPTERA-HETEROPTERA. 


B. constrictus, B. regularis, B. angustatus, &c., but differs from all of them in the short 
(but acute) antenniferous processes, as well as in other particulars. B. rugiventris is 
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., 
belongs to Neuroctenus.

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.

at the sides, the latter crenulate; the anterior portion rounded and slightly dilated at the sides, the 
callosities each with indications of a short ridge; the posterior portion much broader, rounded at the 
sides anteriorly and subparallel behind. Scutellum with a distinct median ridge. Corium rounded at

apical process stout, reaching to beyond the middle of the first antennal joint, feebly emarginate at the 
tip; the spiniform antenniferous processes acute, divergent; the post-ocular portions rather broad, 
dilated laterally into a short, stout spine, which extends to about as far as the eyes; antenne stout,

Hab. Mexico, Temax in North Yucatan (Gauwmer). 


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 
slender legs separate it from B. divisus.

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,

are separated by a rather deep transverse groove, the anterior port on having four 
prominent ridges.

The single small species from which the above-mentioned characters are taken has 
the facies of a Brachyrrhynchus, but differs from that genus in the position of the 
spiracles (the insect in this respect approaching the genus Nannium, Bergr.), as well 
as in having a prominent longitudinal ridge on each side of the anterior part of the 
pronotum. 


1. Coloborrhynchus pumilio, n. sp. (Tab. VII. fige. 11, 3; lla, antenna.) 


3d. Oblong-ovate, flattened above, ferruginous, the basal half of the pronotum, the scutellum, and corium 
fusco-ferruginous ; the membrane nigro-fuscous, obscure luteous round the apex of the corium; the 
upper surface finely granulate, the connexivum almost smooth, and clothed with a few extremely short 
microscopic hairs. Head with a very short spine on each side behind the eyes; the apical process 
reaching to considerably beyond the middle of the first antennal joint; the spiniform antenniferous 
processes moderately long, acute; antenne rather short, moderately stout, with a stouter basal joint, 
joints 1 and 3 equal in length, 2 short, not so long as 4, 4 oblong-ovate, pilose at the tip. Pronotum 
feebly sinuate at the sides, the margins finely crenulate; the anterior portion rounded at the sides 
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 ; 
the lobes of the first genital segment short and stout. Beneath dull and rugulose, the ventral segments 
each with a small smooth spot in the middle, the connexivum partly coated with a pallid incrustation. 

Length 4, breadth 14 millim.

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.

widening from the base to the apex of the third segment, with the fourth segment parallel and the fifth 
and sixth segments broadly and subarcuately dilated posteriorly, the sixth obliquely narrowing and with 
an oblique median fold. Terminal genital segment of the male strongly transverse; the lobes of the 
first genital segment rather prominent. Terminal genital segment of the female subtruncate. Beneath

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


Numerous examples, from the humid forests of the Atlantic slope. Allied to 
N. trigonus, Bergr., from the Pacific slope of Guatemala; differing from that insect, 
in the male sex, in being more widened behind, with the fifth segment more dilated at 
the sides posteriorly, the sixth segment with an oblique median fold (instead of a 
transverse one, as in JV. ¢rigonus), the antenne more elongate and with the apical joint 
shorter than the third.

Two males of this species were found by myself on the Volcan de Agua. They are 
slightly larger than the type, communicated by Dr. Bergroth, and have the upper 
surface a little more coarsely granuJated. All three specimens have a transverse ridge 
or fold on the sixth connexival segment beyond the middle, this being preceded by a 
small tubercle, which is placed near the inner margin.

Of this species we possess nine specimens, eight of which are from Guatemala. 
Recognizable by the broadly dilated, comparatively smooth, connexival segments, which 
are more or less ferruginous in colour, the long and rather slender antenne, &c. The 
insect varies a good deal in size. The sixth connexival segment of the male is without 
a median fold. The type has been examined. The terminal genital segment of the 
female is subtruncate at the apex. A male from Zapote is figured.

Hab. Mexico 23 (coll. Signoret 1), Orizaba (Bilimek, in Mus. Vind. Ces.: 2 ). 


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) 
under the name WV. ovatus, Stal (a pair of which I have seen), belongs to a different 
species, V. pseudonymus, Bergr.* ; it is from North Carolina.

This species, the type (2) of which has been communicated by Dr. Aurivillius, is 
very like XW. litigiosus ; but it is more elongate and has stouter antennex (the third 
and fourth joints are broken off in the type). It is probable that there is some mistake 
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 


specimen of it.

Found in plenty at Capetillo and in Chiriqui. An elongate, narrow, depressed 
species, with the head, pronotum, and scutellum finely granulate; the connexivum is 
almost smooth, finely carinate near the outer margin, and rounded at the sides poste- 
riorly in both sexes; the pronotum is short, trapezoidal, with the sides feebly sinuate 
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 
short spine. One of the types, a male, of NV. rubiginosus, from Cuba, has been seen. 
The terminal genital segment of the female is truncate at the apex. |

This small species is ferruginous in colour; the membrane is fuscous, with two 
luteous marks at the base; the post-ocular spines extend to a little beyond the eyes ; 
the pronotum is short, trapezoidal * ; the corium is short, strongly bisinuate at the 
apex ; the connexivum is broad, rounded externally, the general shape of the insect 
being ovate; the genital lobes (¢@ ) are short and subtruncate at the apex; the antenne 
are about one-half longer than the head, the basal joint extending a little beyond the tip

of the apical process, the fourth joint comparatively short, scarcely so long as the 
second. One of the types, a female, has been examined, and from this our figure is 
taken.

Neuroctenus distanti, Bergr. Ofv. Finsk. Vet.-Soc. Forh. xxix. p. 184 (2) (1887) *. 


‘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.

A female specimen of this species has been communicated by Dr. Bergroth. 
N. niger is separable from most of its allies by the short, stout antenne, the coarsely 
granulate head and pronotum, the latter with the sides not sinuate, the prominent

Hab. Mexico, Oaxaca (Sallé, Mus. Brit.1). 


One male and two females of this species are contained in the British Museum, 
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.

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.

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.

and obsoletely granulate, with acute, outwardly directed, spiniform, antenniferous tubercles and short 
post-oeular spines; antenne about twice as long as the head, joints 1 and 2 oval, 3 and 4 cylindrical, 
4 slightly thickened towards the apex, 1 stout, 2 much more slender and much shorter than 1, 3 longer 
than 1, 4 nearly twice as long as 3. Pronotum subtruncate at the base, rugulose and obsoletely granulate. 
Scutellum nearly or quite as long as the pronotum, and similarly sculptured. Connexivum very finely 
rugulose. Legs rather long, the femora moderately thickened and finely granulate. Terminal genital 
segment of the male long and convex, extending beyond the genital lobes, transversely rugulose. 

Length 5-53, breadth 2-24 millim. (¢ 2.) 


Hab. Guatemata, Totonicapam 8500 to 10,500 feet (Champion). 


Six examples, probably found under pine-bark. This insect approaches the European 
A. levis (Fabr.), and has a similarly formed scutellum ; but differs from it in the acute 
antenniferous tubercles and the longer apical joint of the antenne. It has the femora 
less thickened than in the other Central-American species.

Dr. Bergroth has examined. It is ferruginous in colour and opaque; the antenne 
with joints 1 and 2 oval and 3 and 4 cylindrical, 1 very stout, 2 much more slender and 
a little shorter than 1, 3 slightly longer than 2, 4 twice as long as 3; the head with 
short, spiniform, antenniferous tubercles and acute post-ocular spines ; the legs short, 
with short clavate femora. The general shape is narrowly ovate. The terminal genital 
segment of the male is small and transverse, and does not extend beyond the genital 
lobes. Our figure is taken from a specimen from El Reposo.

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

elytra yellowish at the base. 
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.

Neogeus, Laporte, Essai d’une Syst. Class. Hémipt. in Guérin’s Mag. Zool. 1832, p. 34. 

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. 


* The H. americanus of the Catalogues of Walker and Lethierry and Severin is a Microvelia.

Two specimens. In this insect the antenne have the fourth and fifth joints together 
longer than the third, and the first joint considerably longer than the second; the 
elytra have a long, bluish-white, sharply defined, wedge-shaped mark on the clavus, 
a narrow white streak between the nervures of the corium, and three or four 
conspicuous whitish marks on the membrane; the knees and tips of the tarsi are

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- 
mediate leg, ¢.) 


Rather elongate, black, the pronotum with the disc rufous or fulvous and the anterior margin testaceous or 
flavo-testaceous ; the head reddish-brown on each side between the eyes, in one specimen entirely of that 
colour; the antenne, rostrum, legs, cox, and trochanters, and the apex of the venter, flavous or 
flavo-testaceous, the knees, tibie, and outer joints of the antenne sometimes a little darker ; the elytra 
smoky-brown, with the clavus and the narrow space between the two longitudinal nervures of the 
corium pale brown, the membrane with a narrow pallid transverse streak near the apex of the 
corium; the body, legs, and antenne clothed with short fine pubescence, the venter densely 
clothed with short pallid hairs, the entire under surface with a greyish pruinosity. Head with a very 
fine median groove; antenne about three-fourths the length of the body, 5-jointed, 3-5 very slender, 
1 elongate, more than one-half longer than 2, 3 about as long as 1, 4 and 5 equal in length, together 
fully one-half longer than 38. Pronotum strongly constricted at the sides, and with a fine transverse 
groove before the base; the posterior lobe deeply sulcate down the middle; the surface with scattered

punctures. Scutellum with a fine median carina. Meso- and metasternal carine prominent, the carinze 
continued on to the first ventral segment. 

g. Intermediate femora armed with a short tooth near the base ; second and third ventral segments flattened 
in the middle. 

Length 2;1,-24 millim. (d¢ 9.) 


Hab. Panama, Bugaba and Caldera in Chiriqui (Champion). 


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.

The three Central-American species referred to this genus differ from Hebrus in 
having the antenne 4-jointed*, 7.e. the fourth and fifth joints are fused into one, 
without trace of a suture between them. In J. hebroides, the type of the genus 
Merragata, the joints 1-3 of the antenne are subequal in length; the other two 
species have an elongate third joint. The tarsi are 2-jointed f.

¢. Short, black, the head reddish between the eyes, the pronotum with two, posteriorly confluent, rufo- 
ferruginous spots on the posterior lobe; the elytra with a large triangular white patch on the clavus 
and a very narrow whitish streak between the nervures of the corium, the latter black at the apex, 
becoming paler towards the base, the membrane brown, with three large whitish spots; the antenne 
testaceous, with the apical joint infuscate; the legs testaceous, with the tips of the tarsi (the claws 
excepted) blackish ; the under surface with a bluish-grey pruinosity; the body, legs, and antenne 
finely pubescent. Head with a fine median groove; antenne very short, less than twice the length of 
the head, 4-jointed, 1-3 subclavate and subequal in length, 4 longer and considerably stouter than 3, 
fusiform: Pronotum rugulose, moderately constricted at the sides, longitudinally sulcate down the 
middle anteriorly, the two lobes not distinctly separated. Scutellum distinctly carinate. Legs slender. 
Venter broadly depressed along the middle. 

Length 1,8, millim. 


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.

Short, rufo-fulvous, slightly mottled with fuscous, the venter black, except at the apex; the elytra smoky- 
brown, with a silvery-white wedge-shaped mark at the base of the clavus, the base of the corium and 
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.) 


Short, black or fuscous, the head fulvous in front and on cach side between the eyes, and sometimes with a

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;

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.

Hydrometra, Latreille, Précis des caract. gén. des Ins. p. 86 (1796). 
Limnobates, Burmeister, Handb. der Ent. 1. p. 210 (1835). 

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. 
Ante-ocular portion of the head more than twice the length of the post- 
ocular portion, the head moderately dilated at the apex and slightly 
thickened at the base . . . . . ww ee ee ee ee Carta, Gur.

Hab. Panama, David, Panama city (Champion).—ANTILLES, Cuba !”. 


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. 


Length 93-1014, of the head 3-33, of the abdomen 4—4,), millim. (¢ 2.) 
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. 


3. Hydrometra mensor. 
Hydrometra mensor, Buch. White, Trans. Ent. Soc. Lond. 1879, p. 267 (3) *. 


Apterous form. 2. Brownish-testaceous, the apices of the tibia and of the two basal joints of the antenna, 
the tarsi, the eyes, and the inner and outer raised connexival margins blackish-brown, the pronotum with 
indications of a paler median line. Head scarcely thickened at the base, with the ante-ocular portion 
about twice as long as the post-ocsular portion ; rostrum nearly reaching the base of the head; antenne 
comparatively short, about one-third the length of the body, jot 2 twice as long as 1, 3 twice as long 
as 2, 4 much longer than 2. Metanotum much shorter than the pronotum. 

Length 114, of the head 3, of the abdomen 5? millim. 


Hab. Panama, David (Champion).—Amazons, Manaos ', Santarem. 
One specimen, nearly agreeing with a winged female from Santarem in the British 


Museum. Buchanan White did not mention the form of the antenne. The two sub- 
elongate elevations near the posterior margin of the pronotum (visible in the Santarem 


126 HEMIPTERA-HETEROPTERA. 


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.

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

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.

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

antenne about half the length of the body, joints 1 and 2 subequal in length, 3 and 4 each much more 
elongate, subequal in length, 4 rather stout and fusiform. Legs long, the femora rather stout. Sixth 
ventral segment feebly arcuate-emarginate at the apex. 

Apterous form. 9. Elongate-obovate, flattened above, the venter very convex ; the dorsal abdominal segments 
very little wider than the connexival segments, the latter sloping downwards externally.

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, 
in the ¢. 
a’. Posterior legs moderately elongate; the tibiz strongly 
sinuous in the ¢.

dentate, and the posterior tibie armed with three 
long teeth,inthe d. . . . . . . . « + + = ©Crassipes, N. 8p.

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 
before the tip with a stout tooth; the surface impressed with a few scattered punctures, Elytra extending 
to some little distance beyond the apex of the abdomen, the nervures prominent. Legs stout, the hind 
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 


134 HEMIPTERA-HETEROPTERA. 


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.) 


Apterous form. . Moderately elongate, robust, fusiform, black, the base of the antenns, a narrow transverse 
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

Winged form. g. Moderately elongate, brownish-black, the legs with an seneous lustre, the base of the 
antenne, a transverse band on the front of the pronotum, the prosternum, all the coxe and trochanters, 
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 
line ; antennze moderately elongate, joint 1 rather more than one-half longer than 2, 2 and 3 subequal, 
4 a little shorter than 8, pointed at the tip. Pronotum produced behind into a long spiniform process, 
which is armed with a stout: spine beneath. Legs moderately stout ; anterior tibie dilated in their outer 
half, grooved beneath; posterior femora moderately incrassate, armed with a long tooth at the middle, 
and with a row of short teeth extending thence to the apex, these teeth diminishing in length outwards ; 
posterior tibie slightly sinuate and finely denticulate within, straight on their outer edge, and with 
a short straight tooth at the inner apical angle; posterior trochanters obsoletely denticulate beneath ; 
intermediate tarsi with joints 2 and 3 subequal in length. Ventral segments 1 and 2 and the intercoxal 
portion of the metasternum depressed, the two segments with indications of a median ridge, the sixth 
ventral segment feebly emarginate at the apex and depressed along the middle behind. 

Apterous form. @. Fusiform, the pronotum abbreviated and rounded behind; the posterior femora a little 
less incrassate, with the first (or median) tooth longer and those near the apex shorter; posterior tibi 
straight and finely denticulate on their inner edge. 

Length 52, breadth (of the pronotum of the winged ¢ ) 2 millim. 


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 *.

narrow transverse fulyous mark on each side of the-disc in front, the base of the antenna, the prosternum, 
the coxe and trochanters entirely or in part, the base of the anterior femora, the connexival margins, and 
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. 


Hab. Norta America, Indiana!.—Mexico (coll. Signoret?, in Mus. Vind. Ces.),

Var. Apterous form. 3 @. The anterior femora dark to the base ; the cox and trochanters darker, the latter, 
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 


* In the Vienna Museum there is a winged specimen of an undescribed species closely allied to 2. distincta. 
It is from the Signoret collection, and ticketed “ R. armata, Burm., Centr. America”; but as the localities 
attached to some of Signoret’s specimens cannot be depended upon (his undescribed R. burmenstert being 
labelled ‘Centr. America,” whereas he himself has published it as from La Guayra), the insect is omitted 
from our enumeration

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. 


6. Rhagovelia spinigera, n. sp. (Tab. VIII. figg. 28,9; 284, profile of 


pronotum.) 

Winged form. 2. Moderately elongate, brownish-black, the legs with a bluish-green lustre, the base of the 
antenne, a transverse mark on each side of the disc of the pronotum before the apex, the prosternum in 
great part, all the coxe and trochanters, the anterior femora broadly at the base, the ante-coxal portions 
of the meso- and metasternum, the connexival margins, and the apex of the venter, flavous; the pleura 
and sides of the abdomen bluish-grey; the elytra (the nervures included) blackish-brown; the head and 
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 
basal joints of the antennz also with long scattered sete. Head with a smooth impressed median line; 
antenns moderately long, joint 1 nearly twice as long as 2, 2 and 3 subequal, 4 shorter than 3, fusiform, 
pointed at the tip. Pronotum produced behind into a long, semierect, spiniform process, the surface 
thickly punctured, except along the slightly raised median line, each puncture placed in a small rounded 
depression. Elytra extending beyond the genital segments, the nervures not very prominent, Legs 
comparatively slender, the hind pair rather short; anterior femora feebly sinuous; intermediate femora 
curved in front and concave within, abruptly compressed at the middle; posterior femora curved in front, 
concave on the inner side from the base to near the middle and also before the apex, scarcely stouter 
than the intermediate pair, and armed with a long curved tooth at the middle, and five or six short teeth 
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. 

Length 44, breadth (of the pronotum) 15 millim. 


Hab, Guatemata, San Gerénimo in Vera Paz (Champion). 


One example. In this species the intermediate femora look as if they had been 
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

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.

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.

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.

A widely distributed genus containing ten or eleven described species, two of which 
occur within our limits, whence two others are now added *. In one of the new forms 
described, V. cinctipes, the intermediate legs are very long, with their tarsi much 
longer than those of the posterior legs, as in the European V. currens (Fabr.). In 
V. brachialis and V. annulipes the intermediate legs are shorter, with their tarsi only 
a little longer than those of the posterior legs. ‘The following table will serve to 
separate the three Central-American species known to me. V. vivida was imperfectly

and three white spots at the apex—the inner one lunate, the others rounded ; the body, legs, and antenn»w 
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 
one-half longer, than 2, 2-4 subequal in length, 3 and 4 very slender. Pronotum distinctly punctured, 
rounded at the apex behind; the junction between the anterior and posterior lobes indicated by four 
transversely placed punctures and a triangular lateral depression. Legs comparatively stout, rather 
short; the intermediate tarsi with joint 2 much longer than 3; posterior femora and trochanters very 
minutely denticulate on their inner edge in the male, and faintly so in the female. 

3. Sixth ventral segment deeply arcuate-emarginate at the apex. 

Apterous form. Pronotum abbreviated and subtruncate behind; the elytra sometimes represented by a pair of 
small white wing-pads; the dorsal surface of the abdomen fuscous, the terminal two or three segments 
more or less clothed with glistening silvery pubescence. 

Length 4-5, breadth (of the pronotum in the winged form) 1,®, millim. (¢d 9.)

GUATEMALA, Paso Antonio, San Joaquin in Vera Paz (Champion); Panama, near the city 
(Champion).—Braziu!; ANTILLES, Grenada ?. 


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.

fine, pallid hairs; the base of the abdomen above, the pleura, and venter greyish-pruinose; the three 
terminal dorsal segments of the abdomen, the pleura, the sides of the venter, and an indistinct triangular 
space on each side of the pronotum anteriorly, with patches of glistening 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 than, and nearly twice as long as, 2, 2and 3 
subequal in length (4 broken off). Pronotum longitudinally carinate in the middle anteriorly, distinctly

inwards, and partly separating the anterior from the posterior lobe. Meso- and metapleura laterally 
prominent. Legs long and rather stout; the femora of equal thickness, the hind pair obsoletely denticulate 
along their inner edge; the intermediate tarsi with joint 2 longer than 3. Fifth ventral segment broadly 
produced in the middle behind; the sixth segment very feebly emarginate, with the apical margin 
thickened. Genital segments very prominent. 

Length 5-64, breadth (of the pronotum) 13-2 millim. 


Hab. Mexico (Mus. Vind. Ces., ex coll. Signoret); GuaveMaLa, near the city

Two specimens, one of which was found on a stream at the bottom of a deep barranca 
near the city of Guatemala. Larger, more robust, and more elongate than the apterous 
form of V. brachialis, with more prominent meso- and metapleura, a much longer basal 
joint to the antenne, longer legs, and very differently formed fifth and sixth ventral 
segments in the male. The Guatemalan specimen is figured.

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.

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.

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.

visible between the two teeth ; it is abruptly truncate at the apex. 


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. 


2. Platygerris ceruleus, n. sp. (Tab. 1X. fig. 25, 2.) 


Winged form. 2. Broad, parallel; black, the head, the anterior lobe of the pronotum, the metanotum, pleura, 
and legs with a greenish or bluish-green lustre, the rest of the pronotum nigro-ceruleous; the head with 
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 
stout, a little shorter than the tibia, the latter considerably produced at the apex within. Posterior 
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. 

Length 8, to tip of the elytra 12, breadth 3} millim. 


Hab. Costa Rica, Irazu (Rogers). 


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. 


Head very broad, short, convex, produced and declivous in front, angularly dilated on each side above the 
insertion of the antennex, broadly emarginate behind for the reception of the pronotum; the eyes finely 
faceted, large, oblique, and widely separated; rostrum short, reaching the front of the mesosternum ; 
antenne nearly as long as the body (exclusive of the genital segments), 4-jointed, 1 very elongate, curved 
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 
2-jointed, about half the length of the tibia, joint 1 short, 2 about three times as long as 1, with the two 
claws inserted at about the middle beneath. Intermediate femora a little stouter than, and about two 
thirds the length of, the posterior femora; the latter extremely elongate, and nearly three times the 
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 
with a stout projecting tooth on the lower edge a little beyond the middle. Terminal ventral segment 
deeply arcnate-emarginate at the apex.

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.

One specimen. This species is closely allied to H. flavicollis, Westw., from 
St. Vincent; but in that insect the anterior and intermediate lobes of the pronotum 
are entirely flavous, the intermediate lobe is more developed, and the ocelli are smaller 
and less prominent. 


5. Henicocephalus angustatus, n.sp. (Tab. X. fig. 5, head, antenne, pro- 


notum, and anterior legs.) 


Sparsely pilose, shining, very narrow, rather robust, rufo-piceous, the antenne, rostrum, abdomen, and legs 
testaceous or fusco-testaceous, the elytra pale fuscous. Posterior lobe of the head as long as broad, 
smooth, as wide as the anterior part (including the eyes), convex, unimpressed, the ocelli prominent ;

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.

Very slender, clongate, shining ; pale flavous, the eyes rufo-fuscous, the pronotum with a very fine fuscous line 
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. 

@. Antenne glabrous. Abdomen broader, the genital segments shorter and declivous. 

Length 15-22 millim.

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 :—

In the darkest examples the legs are unicolorous, but in the paler ones they are 
conspicuously annulated with ochraceous. The eyes and the abdominal spiracles are

prominent. The inflated apical portion of the abdomen is somewhat piriform in 
shape in the female. 


2. Ghilianella bulbifera, n. sp. (Tab. X. fige. 17,174, ¢; 18, part of the 


abdomen, °@.) 

Slender, opaque, piceous or obscure ferruginous, the abdomen more or less mottled with black in the female,. 
the inflated portion and the apex of the sixth segment usually black in the male, the legs annulated with 
ochraceous ; finely pubescent, the head and thorax sparsely granulate. Head with a curved yellowish 
frontal spine, the eyes prominent; antennse with joint 2 very little shorter than 1. Pro- and meta- 
thorax subequal in length, the mesothorax more elongate, the meso- and metathorax abruptly widened 
posteriorly. . 

¢. Abdomen with the first and second segments long and narrow; the fourth segment and the apical half of 
the third abruptly, conjointly, and arcuately inflated at the sides, gibbous above and beneath, the third 
dorsal segment feebly subangularly dilated on each side at the apex; the fifth dorsal segment subparallel ; 
the sixth dorsal segment long and moderately acuminate, not quite covering the apex of the terminal 
genital segment, strongly curved upwards posteriorly, without median carina; the long terminal genital 
segment greatly inflated beneath. 

@. 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 
that the Panama specimens mentioned by Prof. Uhler are like the female here referred 
to G. gibbiventris. ‘The larva of G. angulata has the head and thorax strongly 
granulated.

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.

1. Ploiariopsis megalops, Tab. X. figg. 21, 21a.) 

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. (?¢.) 


Hab. Panama, Volcan de Chiriqui (Champion). 


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.

Hab. Guatemata, Capetillo (Champion). 


One example. In this species the long spines on the anterior femora are, with the

PLOIARIA.—BACTRODES. 175 


the described American forms ; it is mentioned here solely to record the presence of 
Ploiaria in Mexico.

Hab. Mexico, Paso del Macho (Hége). 


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 

foliaceous at the sides posteriorly . . . . . . - . biannulatus, St.

Eighteen specimens have been seen of this insect (including the type), the four from 
Omilteme having the body, elytra, and anterior femora much suffused with fuscous. 


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.

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.

Seven specimens. Very like S. recurvata, but evidently distinct, differing from it in 
the rufous coloration of the legs and antenne, and the fascicular arrangement of the 
setee on the lower side of the anterior femora. There is an immature example of 
the same species from Colombia in the British Museum.

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.

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

Oncerotrachelus, Stal, Hemipt. Fabr. 1. p. 130, nota (1868) ; Enum. Hemipt. ii. p. 124, and iv. p. 91 


The chief characters of this genus are the strongly acuminate scutellum, the trans- 
versely globose basal portion of the head, the peculiar neuration of the elytra, and the 
unarmed anterior femora. ‘Two species only are known, one of these (0. conformis, 
Uhler, from the island of Grenada) having an erect tooth at the hind angles of 
the pronotum.

in length. An example from Paso Antonio is figured. 


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 !

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.

182 -HEMIPTERA-HETEROPTERA. 


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 
head.

forwards, carinate at the sides, the anterior lobe canaliculate down the middle, the anterior angles armed 
with a short oblique spine, the hind angles a little swollen. Scutellum produced into a short spine 
behind. Elytra reaching the base of the sixth segment. Abdomen a little rounded at the sides, narrowing 
from about the middle; sixth dorsal segment arcuate-emarginate at the apex; first genital segment

abdomen in the male extends very little beyond the elytra; the fifth segment is 
subangularly dilated at the outer apical angles ; and the sixth segment is subparallel and 
produced on each side at the apex into a short rounded lobe, the apical margin being 
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

from it in the armature of the underside of the head, the position of the eyes, and the 
pointed elytra. The definition given above will supplement that of Stal.

We have received ten specimens of this species, including one larva and one nymph. 
The hind angles of the pronotum vary in shape, being sometimes produced into a sharp 
spine (as in all the examples I have seen from St. Vincent, Grenada, and Texas); in 
S. subinermis, Stal, they are moderately prominent, as in most of the Central-American 


specimens before me.

Two specimens only of this species have been received from within our limits. The 
female is considerably larger than the male, and it has the dark patch on the outer cell 
-of the membrane very elongate ; in the first-mentioned sex the apex only of the second 
joint of the antenne is clothed with long hairs, whereas in the male the antennz are 
hairy throughout, as noted by Stal 2. 


DIADITUS.

p. 128; Enum. Hemipt. n. p. 128, nota. 

The two described species of Diaditus are from Buenos Ayres or Monte Video. ‘The 
two others now added agree very well with Stal’s definition of the genus, but in one of 
them the-.anterior tarsi have their two apical joints almost fused into one, a peculiarity 
also observable in the type of D. semicolon. The head is unarmed beneath, subcylin- 
drical, with the ante-ocular portion a little longer than the post-ocular, and the lower 
anterior portion not extending forwards beneath the base of the jug or frontal spines, 
the latter being long and porrect; the antenniferous tubercles are armed externally 
with .a short oblique spiniform process (appearing emarginate above the points of 
insertion of the antenne); the basal joint of the antenne is not longer than the 
head; the rostrum is short, with the basal joint about reaching to the middle of the 
eyes and as long as the two others united; the anterior femora are unarmed, and very 
little stouter than the others; the posterior femora in the males nearly reach the apex 
of the abdomen; the scutellum is produced into a horizontal spiniform process at 
the apex. 

Antenne rather elongate, with joint 1 almost as long as the head, 2 about one- 
half longer than 1, and clothed with long projecting hairs (3) ; frontal 
spines moderately stout, somewhat pointed ; eyes very large ; anterior ‘tarsi

lines along the middle, connected anteriorly, and the scutellum with a narrow stripe on each side, black ; 
the elytra with the inner margin opposite the apex of the scutellum, a large subtriangular patch on the 
discoidal area, a small oblong spot in the cell in front of it, an elongate patch, deeply excised in front, on 
the outer cell of the membrane, and a small spot at its hase, velvety brownish-black, the rest of the 
membrane slightly mottled with fuscous; the legs flavous, the tarsi and hind femora (the extreme base 
excepted) fuscous, the anterior and intermediate femora mottled with fuscows (except at the base), and 
the anterior and intermediate tibie with the base and apex and an annulus near the middle similarly 
coloured; the connexivum slightly mottled with fuscous; the body beneath ochraceous, the pleura in 
great part and a stripe down each side of the venter, as well as the rostrum, nigro-fuscous; the body 
sparsely clothed with very short scale-like hairs, the legs with bristly hairs; the antenne with joint 1 
finely pubescent, 2 with long bristly hairs all round, and 3 and 4 with much shorter and finer hairs, Head 
with large and prominent ocelli, which are placed on a transverse raised prominence; eyes coarsely 
faceted, very large, prominent, and rounded ; frontal spines (jugs) rather slender, divergent, and some- 
what pointed at the tip; antenne with joint 1 almost as long as the head, 2 comparatively stout, about 
one-half longer than 1, 3 and 4 very slender, 4 a little longer than 3. Pronotum rapidly narrowing from 
the base forwards, as long as broad, with two posteriorly diverging carinz on the disc, the hind angles 
obtuse and slightly raised, the anterior angles produced into a short tooth. Elytra nearly reaching the 
apex of the abdomen. Abdomen gradually narrowing from about the middle, rounded at the sides ; 
the sixth segment at the apex somewhat obliquely truncated on each side and feebly emarginate in the 
centre. Prosternal spines short. Anterior tarsi distinctly 3-jointed.

9. Diaditus pictipes, n. sp. (Tab. XI. fig. 21, ¢.) 

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 
and intermediate pairs with a fuscous ring about the middle, that on the intermediate pair sometimes 
obsolete ; the antenne with joints 2-4 clothed with short fine projecting hairs. Head with the ocelli in 
the male moderately large and placed on a slightly raised prominence, smaller in the female; eyes 
moderately large in the male, smaller in the female, transverse if viewed laterally; frontal spines stout, 
approximate, blunt at the tip; antennz with joint 1 considerably shorter than the head, 2 rather slender, 
about one-fourth longer than 1, 3 and 4 very slender, 4 slightly longer than 3. Pronotum as in 
D. hirticornis. Abdomen with the sixth dorsal segment slightly emarginate in the centre at the apex 
in the male and rounded in the female; the female with two genital segments visible from above—the 
first broad, declivous, and trapezoidal in shape, the second short and strongly transverse. Prosternal 
spines short, Anterior tarsi with the second and third joints almost fused into one.

190 HEMIPTERA-HETEROPTERA. 


Nine specimens from Mexico and one from Guatemala, the latter being broader, 
darker, and more robust than the single Mexican female received. In one example 
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. 


Subfam. SALYAVATINA. 


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.

In this genus the anterior tarsi are 2-, and the other tarsi 3-jointed ; and the antenne 
have their slender third and fourth joints fused into one, so as to appear 3-jointed.

Subfam. ACANTHASPIDINA. 


This subfamily of Reduviide includes a large number of conspicuous insects, most 
of which are found under bark or upon decaying timber. Some of the species of 
Conorrhinus attack man. They all emit a very foetid odour when handled. The 
Acanthaspidine are chiefly confined to the tropics.

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, 
separated by an oblique groove, on each side of the median sulcus;

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.)

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

A Tropical-American genus containing two described species, one of which occurs 
within our limits, whence a third is now added. ‘The characters by which Microlestria 
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.

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. 
Length 5-6, breadth 13-2 miilim. (¢ Q@.) 


Hab. Panama, Volcan de Chiriqui (Champion). 


Three specimens. Very like the Brazilian WM. plebeja, Stal * (the type, 2, of which 
is before me), but smoother and more shining, with longer sete on the body and legs, 
the head smaller and narrower, the general coloration much darker. 


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. 


1. Aradomorpha crassipes, n. sp. (Tab. XII. figg. 8, 8a, 3.) 


3. Reddish-brown ; the head, except in front, and the tip of the scutellar process, blackish ; the membrane 
fuscous, with the base pale flavous, this colour extending on to the apical half of the clavus; the corium 
with the apical third obscurely ochreous, this portion separated from the rest by an oblique curved black 
line; the connexivum ochreous, with the base of each segment broadly banded with fuscous; the legs 
brownish-ochreous, the base of the femora and the intermediate and hind tibie darker; the body, corium, 
and two basal joints of the antenne sparsely, and the legs somewhat thickly, clothed with short, curled, 
decumbent, scale-like, ochreous hairs, the apical two joints of the antenne with finer hairs, the hairs on

the anterior lobe of the pronotum arranged in sinuous lines, Antenne about reaching the median sulcus 
of the pronotum. Pronotum with both lobes rounded at the sides ; the anterior lobe about twice as wide 
as the head, rapidly narrowing forwards, with rather prominent front angles; the posterior lobe wider, 
shallowly sulcate down the middle, and with a few scattered shallow punctures. Abdomen rounded at 
the sides and apex, the genital segments distant from the tip beneath.

Caledonia, which he also records from numerous Eastern localities and from Cuba. 
His Cuban specimen is now before me, and we possess an example from Panama

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 :

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, 
Volcan de Atitlan (Champion). 


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.

Of this remarkable insect we possess five specimens from within our limits, three of 
‘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 
fulvous, with the apex narrowly black; the elytra are fulvous, with the base black ; 
the pronotal and scutellar spines are ochreous, with the base more or less black. The 
type of S. flavispinus was from an unknown locality.

Var. a. The head more or less ochreous in front; the transverse fascia on the posterior lobe of the pronotum 
extending completely across; the scutellar and pronotal spines black, the latter sometimes ochreous or 
reddish at the base; the legs black, the anterior and intermediate femora beneath and the posterior 
femora at the base sometimes flavescent ; the abdomen ochreous, sometimes with the apex broadly black ; 
the transverse flavescent mark before the apex of the corium larger and extending inwards, in some 
specimens continued across the base of the membrane so as to form a common fascia; the curved transverse 
flavescont fascia towards the apex of the membrane usually well-defined. (¢ 2.) 


Hab. Guatemata, Senahu, San Juan, Panima, and Sinanja in Vera Paz, Zapote

the pronotum reduced to a broad patch on the disc; the transverse fascia near the apex of the corium 
moderately large; the curved fascia on the membrane not very distinct. (9 .) 


Hab. Nicaragua, Chontales (Janson); Panama (Boucard). 


The var. a has been found in plenty in Guatemala and Chiriqui; of the var. 6B 
two specimens only, females, have been seen. In the type, which is now before me, 
the scutellar and pronotal spines, and the legs, the posterior tibize and tarsi excepted, 
are flavescent, and the transverse fascia on the corium is reduced to a small spot. The 
legs vary in colour, about half our specimens having the anterior and intermediate 
femora black on the upperside only. We figure a male of the var. « from Chiriqui, 


and a female of the var. 8 from Panama.

Found in numbers on the slope of the Volcan de Chiriqui, and singly at Teleman in 
the Polochic valley. In all the Central-American specimens the pronotum is ochraceous, 
with a black transverse fascia or a line of spots on the disc of the posterior lobe in front, 
and a transverse row of black spots on the anterior lobe behind; the two long spines 
on the disc of the anterior lobe are constantly black. Stal’s Mexican specimens have 


been examined.

Q. Elongate, robust, opaque above, the legs and under surface moderately shining ; sanguineous, fading to 
ochreous, the posterior lobe of the pronotum with two very broad black vitte on the disc, not reaching the 
base, and an oblique black patch on each side in front; the scutellum black in the middle in front; the 
elytra black, with a very large triangular ochreous patch a little before the apex of the corium, extending 
narrowly along the costa to the base and inwards to the base of the membrane ; the connexival segments 
each with a black patch at the outer apical angles ; the antenna, and the apical joints of the rostrum in great 
part, black; the legs black, with the base of the hind femora very narrowly, and that of the other femora 
broadly, sanguineous, the tarsi fuscous; the body and legs sparsely clothed with long hairs, the antenne 
finely pubescent, with longer hairs intermixed. Head oblong, the juge not raised, the gene obtuse at 
the apex, the eyes very large, the ocelli large and prominent; antenna moderately elongate, joint 1 short, 
about reaching the ocelli, and less than one-fourth the length of 2. Pronotum almost smooth, strongly 
constricted at the sides before the middle; the anterior lobe short, one-half the length and about one-half 
the width of the posterior lobe, unarmed, shallowly and obliquely bisulcate on each side of the disc; the 
anterior angles stout, obliquely prominent, obtuse at the tip; the transverse median sulcus widened out 
into a deep fovea in the centre; the posterior lobe strongly dilated, the hind angles obtuse and raised, 
the basal margin reflexed. Scutellum produced into a long semierect spine. Elytra extending to beyond 
the abdomen. Legs elongate, rather stout; femora unarmed; anterior and intermediate tibie with a 
very elongate fossa beneath, extending to the middle; posterior tarsi with joint 3 a little longer than 2. 
Ventral segments 2-4 sharply carinate. 

Length 31; breadth of the abdomen 9, of the pronotum nearly 8 millim.

Hab. Nicaraaua, Chontales (Janson).—Gutana, Cayenne?; Brazin}. 


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

I have seen twenty examples of this species (including one of the Mexican types), all 
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.

_ An abundant insect in the forest-clearings of the “ tierra caliente ” of Chiriqui. The 
larva of this species has on the disc of the pronotum two very long spines, which are 
erect to near the middle and then curved forwards (fig. 19); a specimen was found at 
Teleman with the fully-developed form.

Triatoma, Laporte, loc. cit. p. 11. 

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.

Q. Moderately elongate, opaque, the body almost glabrous; nigro-fuscous, a broad space along the middle of 
the venter, the covered portion of the dorsal surface of the abdomen, the hind angles of the pronotum, 
the outer margin of the corium to about one-third from the base and a small indistinct spot at the middle 
of its apical margin, brownish-ochreous ; the connexival segments 1-5 each with a narrow transverse 
ochreous or reddish-ochreous fascia at the apex ; the femora brownish at the base; the membrane dilute 
fuscous. Head transversely rugulose, with the produced apical portion parallel, stout, and a little longer 
than the antenniferous processes, which are as long as the large and moderately prominent eyes, the 
post-ocular portion short, the ocelli prominent ; antenne pilose, joints 3 and 4 with long projecting hairs 
intermixed, 2 about three and one-half times longer than 1, 1 reaching as far as the apex of the head ;

tubercles ; the anterior angles obtusely dentiform, short ; the posterior lobe with two anteriorly converging 
carine on the disc in front; the hind angles obtuse. Scutellar process horizontal, moderately long. 
Elytra reaching the apex of the sixth segment. Connexival margin moderately broad. Anterior and 
intermediate femora each with four very short teeth beneath before the apex—two on the anterior and 
two on the posterior edge.

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.

is very like that of Hammatocerus purcis (Drury) and H. luctuosus, Stal, the base being 
very broadly banded with whitish.

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.

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.

Hab. Panama (Boucard).—Guiana, Surinam! 45; Amazons, Pard®; Brazt‘. 


We have received a single male example of this beautiful Tropical-American insect, 
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.

Hemipt. ii. pp. 105, 108, and iv. p. 56. . 
A monotypic Tropical-American genus, extending northwards to the Mexican State 
of Vera Cruz. It is closely allied to Rasahus, Amy. et Serv., but differs from it in 
having the metapleural sulcus distant from the margin. The pronotum is smooth and 
shining, and the anterior lobe is without oblique sulci on the disc. The meso- and 
metasternum, and the three basal segments of the abdomen, are carinate down the 

middle, the carina not extending so far downwards in the female as in the male.

Two males and one female are referred to this species, the female nearly agreeing 
with one of Stal’s specimens of the same sex from Surinam in the Stockholm Museum. 
The males have more slender legs than the females, and the eyes a little larger and 
more prominent. The wings are whitish. In WM. picipes* and M. abdominalis 
(Herr.-Schaff.) the eyes are smaller and more widely separated in the males. St&l’s 
types of MM. picinus and M. picicornis have been seen. M. (Pirates) degener, Walk., 
is a close ally of M. morio.

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.

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 
concisus, Walk.; the last-mentioned insect is not separable from &. hamatus. No 
locality was given by Walker for Pirates indecisus 18 and P. contiqguus'*. One of 
Stal’s specimens of R. hamatus, from Minas Geraes, Brazil, has been seen, with which 
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.

An American genus, ranging from the United States to the Argentine Republic; 
eight species have been described *, one only of which enters our limits, whence three 
others are now added. They differ from the allied forms in having the post-ocular 
portion of the head more or less elongated and cylindrical behind. ‘The antenne are 
8-jointed, as in the genus ctrichodia. These insects appear to be rarely found, six 
specimens only, representing four species, having been seen from Central America.

One specimen, somewhat discoloured. In the form of the head this species approaches 
P. lugens, but the eyes are much more prominent, the ante-ocular portion of the head

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.

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.

I have seen nine specimens of E. cinctiventris, including one of the types, all males. 
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.

nothing more than colour varieties of others, the genus ranging from the Southern 
United States to the Argentine Republic.

sexes, and the depressed portions of the second and third are densely pilose in 
the males.

We have received thirty-eight specimens of this species. It seems to be not 
uncommon in Yucatan. The larva was sent with the perfect insect from Presidio by 
Forrer and from Yucatan by Gaumer; it has the tarsi 2- (instead of 3-) jointed, and 
the hind femora to near the tip, as well as the others at the base, rufous. Stal? 
mentions a variety with the connexivum immaculate, but I have not seen a specimen 
of it. A male of H. ductuosus from El Reposo is figured.

In this species all the femora have a broad rufous or rufo-testaceous band near

Southern United States, which has the hind femora only banded with red. H. cinctipes 
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.

Of this species we possess a long series of examples from within our limits, these 
agreeing perfectly with one of Stal’s types of H. annulipes now before me. Perty’s 
figure, there can be little doubt, must have been taken from a specimen of the same 
species, the differences observable being evidently due to the imperfect drawing of the 


artist. ‘The coloration of the pronotum and elytra is quite constant. A male from 
Pantaleon is figured.

3. Homalocoris binotatus, n. sp. (Tab. XIII. fig. 25, 2.) 


Q. Elongate, rather broad, black; the pronotum with two oblique reddish-ochreous vitte: on the disc of the 
posterior lobe; the clavus sordid ochreous, with the extreme apex and an oblong patch on the inner part 
about the middle black ; the corium sordid ochreous, with a large oblique black spot on the disc beyond 
the middle; the membrane with a very broad angulated fascia (formed by confluent longitudinal stripes) 
extending completely across the basal portion, the part adjoining the corium narrowly and the apex 
broadly pale; the connexival segments each with about the basal half ochreous ; the tarsi fusco-testaceous ;

Subfam. APIOMERINA. 


Of the fifteen recognized genera of this subfamily of Reduviide, eleven are

are tropical. 

AGRIOCORIS.

A Tropical-American genus including two or three species, one of which is a common 
insect in the “tierra caliente ” of Chiriqui. 

The form of the apex of the terminal genital segment of the males is very different 
from that of the same sex of Apiomerus.

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 
having the base of the pronotum produced into a prominent rounded lobe on each side of the median 
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. 


APIOMERUS. 231 


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.

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

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

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.

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.

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 
segment, ¢ .) 

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 
the abdomen in both sexes. Legs stout, the femora slightly swollen before the tip. — 

3. Terminal genital segment strongly transverse, armed with two widely separated, moderately long, upwardly 
curved, divergent spines, the apical margin with a short tooth on each side above the points of insertion of 
the claspers (appearing emarginate laterally); the latter comparatively short and stout, and abruptly bent 
inwards beyond the middle. 

©. Venter thickly pilose. 

Length 163-18, breadth 6-74 millim. 


Hab. Mexico, Tepic (Schumann). 


One pair. Very like A. subpiceus, Stal, but differing from it in the more thickly 
setose body and the distinctly mottled membrane; the male is more robust than the 
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.

APIOMERUS. 239 


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 


genital segment, ¢ .) 

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 
as 2, 4 slightly shorter than 3. Pronotum with the base feebly sinuate on each side near the hind 
angles. LElytra longer than the abdomen in both sexes. Legs moderately stout, the femora feebly 
swollen before the tip. 

3S. Terminal genital segment armed with two very long, stout, tapering, upwardly curved, divergent spines ; 
the claspers long and stout, and abruptly bent inwards towards the tip.

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.

240 HEMIPTERA-HETEROPTERA. 


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 
margin of this segment being thickly clothed with long hairs in the centre, and armed 
with a short tooth on each side opposite the points of insertion of the claspers; the 
latter are moderately long, rather stout, and abruptly bent inwards beyond the middle.

‘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.

with tbe apical margin narrowly ochreous. The males have the apex of the terminal 
genital segment broadly produced in the centre, and armed on each side with a — 
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 ( ? ) 
specimen from Omilteme has the pronotum black, with a small spot on each side 
of the posterior lobe in front and the anterior angles rufous, and the corium obscure 
rufo-piceous.

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.

APIOMERUS. 243 


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.

Subfam. HARPACTORINE. 


This subfamily, the Reduviina of Stal, is the most numerous in species of any of the 
groups of the Reduviide, Lethierry and Severin enumerating 717 species and 137 
genera as belonging to it. Some of the species of Milyas, Zelus, Repipta, Ricolla, &c.

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.

Hab. Panama, Volcan de Chiriqui (Champion). 


A common Central-American insect, separable in all its varieties from the North- 
American M. cinctus (Fabr.) by the longer and deeper sulcus on the disc of the 
pronotum, and the sulcate spine at the apex of the last genital segment in the males. 
The markings on the pronotum are variable, the black sometimes (in the typical form 
and in the var. «) predominating so as to enclose pale spots on the posterior lobe, 
and sometimes becoming almost obsolete; the lateral teeth are, however, always black. 
The second pale ring on the first antennal joint is frequently obsolete or indistinct. 
The posterior lobe of the pronotum, except at the base, the scutellum, and connexivum 
are often suffused with red. The pleura and the sides of the venter are each marked

with a row of tomentose white spots. The males have the apex of the last genital 
segment produced in the middle and armed with a sulcate, pointed spine of variable 
length ; the outer genital lobes are narrow and the short inner lobes blunt at the tip.

Nine specimens, most of which are in a bad state of preservation. /. infuscatus is 
probably an extreme form of the very variable MM. zebra, but as it appears to be 
localized in Guatemala I have ventured to name it. In some examples the black 
markings on the venter are so extended as to enclose four series of large transverse 
pale spots.

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.

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.

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.

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. 


* Prof. Uhler (Bull. U.S. Geol. & Geogr. Surv. i. p. 327) records this species from Mexico, possibly 
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

as long as the pronotum, very gradually narrowing behind the eyes, the post-ocular portion longer than 
the ante-ocular portion ; antennz very slender, as long as the body, joint 1 longer than the head and 
pronotum united. Pronotum longer than broad, depressed along the middle, the anterior lobe with a

hind femora. 

g. Third antennal joint thickened to beyond the middle, and the terminal genital segment armed at the apex 
with a long, upwardly curved, hooked spine. 

Length 11-13, breadth 2-23 millim. (¢ 9.) 


Hab. Mexico, Ciudad and Milpas in Durango, Presidio de Mazatlan (orrer), 
Hacienda de la Imagen, Xucumanatlan, and Chilpancingo in Guerrero (H. H. Smith) ; 
GuaTEMALA, San Gerénimo (Champion). 


Ten examples, one only of which is from Guatemala. This insect is closely allied to 
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 
than usual. The six small spots on the anterior lobe of the pronotum are glabrous and 
well-defined. The larva (from Milpas) has a long black spine at the sides of each of 
the abdominal segments. 7 | —

Hab. Mexico, Orizaba (Bilimek, in Mus. Vind. Ces.).—Braziu }?. 


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.

The type of this species (now before me) is a female, and we have received three 
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), 


ZELUS. 259 


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.

Zelus (Diplodus) umbratilis, Stal, Enum. Hemipt. ii. p. 91‘. 


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

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.

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

be separated eventually, as it has the intermediate and posterior tibise peculiarly 
formed. The terminal genital segment of the males of our species is unarmed and 
simply rounded at the apex. Some of the Notocyrti are very variable in colour, and

the pronotum with the anterior lobe flavous in front, the posterior lobe with the anterior portion entirely, 
and two triangular patches on the disc beyond, these latter connected behind, nigro-piceous or black ; the 
elytra testaceous, with the membrane subhyaline; the abdomen with the dorsal segments 4—6 broadly 
infuscate across the middle, the ventral segments 3-5 each with a transverse oblique dark streak at the 
sides ; the antenne blackish, with joint 1 beneath and 2 and 3 at the base obscurely flavous; the rostrum 
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 
each armed with a short, stout tooth. Elytra extending to a little beyond the abdomen. Legs stout ; 
the femora moderately incrassate, the posterior pair considerably swollen before the apex above; the 
anterior tibia curved; the intermediate and hind tibie flattened or excavate along their outer face, and 
also hollowed along their inner face, appearing triangular in shape, the intermediate pair becoming 
moderately and the hind pair enormously incrassate towards the middle; the femora and tibiz densely

We possess two males and three females of this species, all but one of which were 
found by myself in Chiriqui. They are very variable in colour, the three bluish-black 
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.

pp. 68, 84. 

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

converging carinsz on the disc extending from the spines forwards. LElytra a little longer than the 
abdomen. Abdomen with a long, straight, posteriorly directed spine at each of the outer apical angles of 
the sixth connexival segment; the segments 1-5 in the male, and 1 and 2 in the female, each armed 
with a spine at the outer apical angles, the first three spines in the male longer than the others. 

Length 12-14, breadth 2-23 millim. (¢ 2.) 


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


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.

Zelus, but they may be easily separated therefrom by the comparatively short second

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

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,

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 
de Chiriqui, Caldera (Champion). 


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

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 
(except in &. tuberculigera), the head and posterior lobe of the pronotum armed with 
long spines or tubercles, the outer area of the membrane nearly or quite as long as 
the inner. A. octispina should perhaps be separated, it having a differently formed 
scutellum. .

1. Rocconota rufotestacea, n. sp. (Tab. XVI. fig. 19, 2.) 


. Very elongate, sparsely pilose ; rufo-testaceous, the membrane smoky-hyaline, with the nervures partly 
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.

Hab. Mexico, Atoyac in Vera Cruz (Schumann). 


One specimen. ‘This species is very like Heza similis, agreeing with it in the 
armature of the pronotum, but differing from it in the non-plicate mesopleura, as well 
as in the posteriorly narrowed head, &c. The insect is probably bright red in life. 


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. 


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


One specimen. Very like &. annulicornis, but smoother and more shining above and 
beneath, the second connexival segment, as well as the first, armed with a long spine, 
the anterior angles of the pronotum obtuse, the under surface clothed with long hairs 
only. The head is much more elongate than in KR. octispina. 


3. Rocconota annulicornis. (Tab. XVI. fig. 21, ¢.) 
Heza annulicornis, Stal, Enum. Hemipt. ii. p. 77'; Uhler, Proc. Calif. Acad. Sci. (2) iv. p. 283°.

(Champion). 

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. 

Length 144-19, breadth of the abdomen 3-5 millim. (¢ 2.) 


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


Two males and one female. Near F&. annulicornis, but with the legs more broadly 
annulated with fuscous, the body more sparsely pubescent, the elytra relatively longer, 
with the longitudinal nervure of the membrane more or less infuscate, the anterior 
angles of the pronotum more obtuse, the under surface with long scattered hairs only.

In some of our examples of this species the spines on the head and pronotum are 
quite short, as in the types (one of which is before me), and the two on the disc of the 
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 
of the scutellum is produced into a rather stout upwardly curved spine. The males 
have the third antennal joint slender, and the terminal genital segment armed with a 
short tooth at the apex. A specimen from Acapulco is figured.

We possess twelve specimens of this peculiar species, agreeing with the type ( ? ) 
now before me. In this insect the scutellum is covered with a dense white agglutinated 
tomentum, forming a heart-shaped patch, and the pronotum, corium, and pleura are 
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,

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.

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.

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.

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

Amongst our long series of this species there are three specimens only of the dark 
variety. ‘The males have the third antennal joint thickened to about the middle, and 
the terminal genital segment emarginate at the apex and armed with a long, slender, 
upwardly curved spine. A specimen from Atoyac is figured. 


2. Castolus tricolor, n. sp. (Tab. XVII. fig. 4, 3.) 


Stramineous or ochraceous, shining, sparsely pubescent; the head, the cylindrical basal portion excepted, partly 
or almost entirely black above ; the pronotum with the posterior lobe black, the anterior and hind margins 
excepted ; the elytra with a common transverse black fascia some distance below the base, the corium 
thence to the apex sanguineous, the membrane subhyaline; the abdomen with the dorsal segments, the 
connexivum, and the sides and apex of the venter, sanguineous, the dorsal segments 1-5 more or less 
suffused with black in the middle, the ventral segments with narrow transverse black fasciz ; the antenne 
piceous or black, with joints 3 and 4 paler; the legs piceous or black, with the intermediate and hind 
femora partly or entirely stramineous to near the apex, the intermediate femora sometimes with a faint 
median ring only. Head much narrowed behind, armed with a short conical tubercle on each side before 
the eyes, the latter large and prominent in the male, smaller in the female; antenne with joint 1 slightly 
longer than 3, 2 short, 4 longer than 2. Pronotum a little longer than the head, with the lateral angles 
rounded, and the anterior angles obtuse ; the anterior lobe smooth, sulcate down the middle, the posterior 
lobe with two short anteriorly converging carine on the disc in front. Elytra extending far beyond 


the abdomen. 
¢d. Antennex with joint 3 thickened to near the middle. Last genital segment armed with a long filiform

Found in plenty in Guatemala, sparingly elsewhere. This very distinct species, 
which appears to have been unknown to Stal, is a close ally of C. plagiaticollis, but 
differs from it in the coloration of the elytra, and in having much larger eyes in the 
male. A specimen from Teapa is figured. 7

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. 
Length 12-124, breadth 5-53 millim. 


Hab. Mexico, Omealca in Vera Cruz (VM. Trujillo); Guaremata, Chacoj in Vera Paz 
(Champion). 


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.

(1866) ; Enum. Hemipt. ii. pp. 69, 82. 


A Tropical-American genus including three or four species. It is very closely allied 
to Graptocleptes. These insects greatly resemble various Ichneumonide and Braconide, 
and they are variable in colour. The head above and beneath is densely pilose, and 
the wings and elytra are banded with black; the third antennal joint is thickened 
in the males.

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. 
Graptocleptes, Stal, Ofv. Vet.-Ak. Forh. xxiii. p. 294 (1866) ; Enum. Hemipt. ii. pp. 69, 81. 


A Tropical-American genus including eight described species, one of which occurs in 
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. 


Head flattened and with a few scattered hairs only beneath ; body flavo- 
testaceous, the pronotum and elytra variable in colour, the elytra with 
the apex and sometimes a median fascia also black or fuscous . . . varians, n. sp.

the anterior lobe of the pronotum and the venter sometimes sanguineous; the head black, with the neck 
flavescent, or entirely flavescent, the rostrum included; the pronotum with a black vitta down each side

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.

We possess eleven specimens of this species and four others belonging to the Vienna 
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.

Seven examples, all females, like the type. This species is very like Graptocleptes 
sanguineiventris, but has stouter and more hairy legs, the posterior tibia are unequally 
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. 
An example from Amula is figured. |

whitish tomentum ; the rostrum, the cephalic spines, the connexival margins, and the basal joint of the 
-antenne in great part (the other joints broken off), flavous; the legs also annulated with flavous. Head 
armed in front with two exceedingly long, slender, erect spines, these being longer than those on the 
pronotum, the post-ocular portion a little longer than the ante-ocular portion; the basal joint of 
the rostrum reaching slightly beyond the eyes; antenne slender. Pronetum armed with two long 
spines on the disc and with a similar spine at each of the lateral angles. lytra reaching the apex of the 
abdomen. Abdomen with the connexival segments 4 and 5 each armed with a very short spine at their 
outer apical angles (the spine on the fifth segment a little longer than that on the fourth), the other 
segments unarmed, the sixth rounded at the apex. Legs slender, the anterior femora feebly incrassate. 

Length 73, breadth of the abdomen 11 millim. 


Hab. Panama, Bugaba (Champion). 
One specimen. Narrower and more elongate than A. cinereus, with the fourth and 
fifth connexival segments only spinose, the cephalic spines exceedingly elongate, the 


post-ocular portion of the head relatively longer (approaching the genus Phorodura in 
this respect), the legs more slender. The antenne are, unfortunately, imperfect.

A common insect in Chiriqui. Our specimens vary from 15-24 millim. in length. 
Some of them are of an olivaceous or greenish colour. In fresh examples (as in certain 
species of Rocconota) the pronotum, scutellum, and corium are set with scattered points 
of whitish tomentum. The third antennal joint is slender in both sexes. WH. similis 
is very like Rocconota rufotestacea and other species of that genus, but it is easily 
| distinguishable from them by the plica on the mesopleura. One of Stal’s Colombian 
specimens has been seen. We figure a pair from Bugaba.

erect hairs; obscure ferruginous, the body-beneath, the legs, and antenne testaceous or rufo-testaceous, 
the elytra fuscous, with the membrane hyaline or yellowish-hyaline; the posterior lobe of the pronotum 
with a transverse row of six or eight spots in front, the elytra with numerous partly confluent spots on 
the cuneus and basal portion of the corium, as well as a small spot on the disc of the latter behind, a spot 
on the propleura in front, two on the mesopleura, one on the metapleura, one on the scutellum, and one 
on each of the posterior angles of the pronotum, white- or golden-tomentose; the legs clothed with long 
erect hairs. Head shorter than the pronotum, with two short erect spines, the eyes moderately large in 
both sexes, the neck-like basal portion cylindrical and rather stout; (antenne imperfect). Pronotum with 
two blunt erect spines on the disc of the anterior lobe and laterally projecting conical anterior angles; the 
posterior lobe with two long acute spines on the disc and one at each of the lateral angles. Elytra 
extending to the apex of the abdomen. Abdomen in both sexes with the first segment only armed with 
a short spine at the outer apical angles, rounded at the apex. Legs very elongate, the anterior femora 
strongly incrassate. Rostrum with the first joint about as long as the two others united.

to the same section of the genus as H. linotata (Lep. & Serv.), H. insignis, Stal, and 
Hi. ventralis, Stal. 


3. Heza fuscinervis, n. sp. (Tab. XVII. fig. 21, ¢.) 

Very elongate, rather robust, opaque, thickly griseo-pubescent and also with a few scattered erect hairs, the 
legs pilose; griseous or griseo-testaceous, the head, pronotum, and under surface more or less streaked 
or spotted with fuscous, the connexival segments sometimes maculated with yellow, the nervures of the 
membrane partly black, the legs more or less annulated with fuscous ; the pleura in fresh specimens with 
spots of whitish tomentum; the antenne with joint 1 fuscous, with two pale rings, 2-4 testaceous, 
2 fuscous at the apex. Head nearly as long as the pronotum, with two very long, acute, slightly curved 
spines, the neck-like basal portion stout and cylindrical, the eyes moderately large in both sexes. 
Pronotum with two blunt or subacute moderately long spines on the disc of the anterior lobe and conical, 
moderately prominent anterior angles; the posterior lobe with two very long acute spines on the disc and 
one at each of the lateral angles. Elytra extending to the apex of the abdomen. Legs very elongate, 
the anterior femora strongly incrassate. Rostrum with the first joint as long as the two others united. 

g. Abdominal segments 1~3 each armed with a spine and 4-6 angularly or acutely dilated at the outer apical 
angles, the apex of the sixth appearing deeply emarginate; terminal genital segment with an upwardly 
curved spine at the tip. 

2. Abdominal segments 1-3 armed with a short spine at the outer apical angles. 

Length 23-29, breadth 4-63 millim. (¢ 9.)

Three males and one female. ‘This large species is allied to H. sericans, H. oculata, 
and H. multiannulata, Stal, from Brazil, but, to judge from the descriptions, distinct 
from all of them *. Males only of this group were known to Stal. The spines on the 
head and anterior lobe of the pronotum vary in length, and those on the latter are 
acute in some specimens and blunt in others. In one of the males the angles of the 
sixth connexival segment are acutely produced. ‘The third antennal joint is slender in 
both sexes.

An American genus including several very closely allied species of large size, 
remarkable on account of the greatly developed and peculiarly formed posterior lobe 
of the pronotum, this latter being more or less cristate down the middle and set with a 
row of smooth shining black tubercles, and at the base there are two stout spines. 

They prey upon small insects which live upon trees and bushes, and are able to 
inflict a very painful wound. The three species occurring within our limits may be 
separated thus :— . 


Posterior lobe of the pronotum convex and strongly cristate. 
Margins of the abdomen distinctly sinuate; the sides of the pronotum not 
or scarcely dilated behind the postero-lateral angles . . . « « « cristatus, L.

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.

Plentiful in forest-clearings on the slope of the Volcan de Chiriqui. This species is 
very like A. cristatus, but differs from it in having the sides of the pronotum distinctly 
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.

posterior lobe of the pronotum feebly convex on the disc, with the crest very little 
raised and set with about eight tubercles, and the spines at the base are less divergent ; 
the margins of the abdomen are feebly sinuate.

(De G.) (an example of which has been sent me by Prof. Uhler); but it has a less 
elongate head, and the spiniform elevations on the head and anterior lobe of the 
pronotum are not nearly so prominent. The males (unknown to Stal) have a narrow 
abdomen. We figure a pair from Orizaba.

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. 


8. Sinea caudata, n. sp. (Tab. XVIII. figg. 8, 8a, 3; 9, 2.) 


Moderately elongate, the abdomen narrow in the male, much broader in the female; sparsely pilose and 
pubescent, fuscous or griseo-fuscous, the connexival segments each more or less distinctly marked with 
flavous towards their outer apical angles; the body beneath, the intermediate and hind tibiz, and the 
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.

_ 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.

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 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.”

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.

NoreE.—In my enumeration of the species of Apiomerus, antea, pp. 230-243, 
A. (Herega) rufipennis, Fallou, from Mexico (Le Nat. 1889, p. 131) was accidentally 
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.

Two specimens, found under leaves &c., in marshy places, in the low country 
bordering the Pacific coast, in 1880. They are a little larger than the examples 
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 :—

Q. Macropterous form.—Moderately elongate, robust ; clothed with scattered sete, the abdomen, scutellum, 
corium, clavus, legs, and antenne also sparsely pilose; the intermediate and hind tibizee with a few very 
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. 

Length 632, breadth 24 millim. 


Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith).—Soura America }, Tapajos!. 


One specimen. Very like P. enescens, Stal, from Brazil, but differing from it in 
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. 

Stal’s types of P. enescens and P. pallidiceps have been seen.

Moderately elongate, clothed with Iong scattered sete, the abdomen, legs, and antenne also sparsely 
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.

sparsely pilose ; nigro-piceous, the head reddish in front, the pronotum with an eeneous lustre; shining, 
the scutellum and clavus opaque; the legs and rostrum testaceous, the posterior femora darker at the 
apex. Antenne as in P, fuses, but with joints 3-5 more elongate. Rostrum very long, reaching the 
intermediate coxe; joint 2 a little longer than 3, extending as far as the front of the anterior coxe. 
Eyes large. Pronotum as in P, fusca. Corium extending slightly beyond the first abdominal suture, 
rounded at the apex, the membrane reduced to a narrow strip along its inner apical margin. Anterior 
tibie broadly and abruptly widened on the inner side from about the middle to the apex. 

Length 61, breadth 27 millim.

A very widely distributed genus, two of the three described American species occurring 
within our limits. In these insects, as in the Palearctic A. flavipes, Fieb., the anterior 
femora are strongly incrassate and angularly dilated on the lower side a little before 
the middle, with the lower margin finely denticulate thence to the apex, the intermediate 
‘pair being similarly formed, but more slender; the anterior tibie are also abruptly 
dilated on the inner side at the apex, with a spongy fossa extending along the widened 
portion.

Some authors, including Stal, adopt the name Coriscus, Schrank [Fauna Boica, i. 2, 
p. 46 (1801) ], for this well-known genus ; but as Schrank subsequently gives (op. cit. 
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 
least two of the Central-American species the elytra vary in length in these forms.

in Guerrero, Cuernavaca in Morelos (H. H. Smith). 


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.

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

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.

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.

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 
immature. 


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.

Hab. Guatemana, Cerro Zunil 4000 feet (Champion). 


One specimen. Very like L. punctipennis, but with the eyes smaller, the pronotum 
less narrowed in front, the head and pronotum rufo-testaceous. This and the preceding 
species differ from the Venezuelan L. unicolor, Reut. (the type of which is before me), 
in their more ovate shape, and in having the elytra duller, more distinctly punctured, 
and with the embolium much broader behind.

a short median sulcus behind; the posterior lobe depressed on the disc and transversely rugulose. 
Scutellum transversely rugose behind. Elytra with the clavus, corium, embolium, and cuneus sparsely, 
very finely punctate; the embolium at the apex as wide as the corium; the membrane with a single 
(outer) nervure only distinct. Orifice of the metastethium short, curving backwards. 

Length 24 millim. (¢ 9.) 
Hab. Guatema.a, El Tumbador, Las Mercedes, Torola (Champion); Panama, Bugaba 


(Champion). 


Eight specimens, all from the Pacific slope. Allied to Z. varicolor, Uhler, from the 
Island of Grenada, but larger and duller, and with the apical half of the embolium 
infuscate or black. From L. fusculus, Reut., the type of which is before me, it differs 
in the coloration of the elytra, the less produced anterior portion of the head, &c.

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,

Hab. Panama, David in Chiriqui (Champion). 


One specimen. This species is distinguishable from the other Central-American 


310 HEMIPTERA-HETEROPTERA. 


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

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 
ante-apical groove. L. sulcicollis, Reut., from Brazil, is an allied form. 


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 
of the elytra slightly shining ; pale testaceous, the eyes and the basal joint of the antenne blackish. Head 
about as broad as long, the eyes small; rostrum reaching the middle of the mesosternum ; antenne with 
joint 2 about two and one-half times the length of 1. Pronotum almost smooth, rounded at the sides in

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.

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 


BIOL. CENTR.-AMER., Rhynch., Vol. Il., Aprid 1900. 40

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.

3. Piezostethus albonotatus, n. sp. (Tab. XIX. figg. 10, ¢; 10a, anterior 
leg, 3.) 


Short and rather broad, clothed with a very fine scattered pallid pubescence and also with widely scattered 
long erect hairs; shining, the apical half of the scutellum, the clavus and corium, and the basal half of the 
embolium, opaque; black, the embolium more or less ochreous in its basal half, the corium nigro-fuscous 
or fuscous, with a subquadrate transverse whitish patch about the middle, the membrane in great part 
fuscous; the apical joint of the rostrum testaceous; the antenuze and legs black or piceous, the tarsi 
obscure testaceous; the mesosternum piceous. Head broader than long, smooth, the eyes large; rostrum 
reaching almost as far as the intermediate coxe; antenne with joints 1 and 2 moderately thickencd, 
2 becoming stouter towards the apex, 3 and 4 more slender, 2 longer than 3 or 4, the latter subequal in

half of the scutellum opaque, the third and fourth antennal joints a little stouter, the 
eyes larger, the orifice of the metastethium transverse, &c. The wings have the hamus 


issuing beyond the decurrent nervure.

Very like P. albonotatus, but with the whitish mark on the corium oblique and placed much nearer the base, 
the tibie, except at the extreme base, and the tarsi ochreous; the pronotum distinctly sinuate at the 
sides; the membrane becoming hyaline towards the outer margin; the orifice of the metastethium a little 
longer and slightly curving forwards externally.

PIEZOSTETHUS.—ASTHENIDEA. 517 


Two specimens. This insect is so like P. albonotatus in its general characters, that 
a more detailed description is unnecessary. 


ASTHENIDEA. 
Asthenidea, Reuter, Monogr. Anthocorid. pp. 5, 48 (1884). 
? Calliodis, Reuter, Ofv. Vet.-Ak. Forh. 1871, p. 558; Monogr. Anthocorid. p. 154; Stal, Enum. 
Hemipt. iti, p. 101. . 

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 :— 

Legs partly piceous ; elytra ‘ochreous, with two dark fascie . . . . . . . mebulosa, Uhler. |

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.) 


‘Hab. Panama, David and Tolé in Chiriqui (Champion). 


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. 319 


Division ANTHOCORARIA, Reuter. 


The species of this section of the Anthocorine have the third and fourth antennal 
joints comparatively stout, and the wings with a hamus in the cell. | 


MACROTRACHELIA. 
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.

long as 1,3 much shorter than 2. Rostrum reaching to a little beyond the apex of the prosternum. 
Pronotum rapidly and obliquely narrowing from the base forwards, the two lobes separated by a very 
deep transverse groove, Orifice of the metastethium short and transverse. 

Length 34 millim. (¢.) 


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


One specimen. Very like M. elongata and M. albovittata, but with the antenne 
shorter, stouter, and entirely black, the eyes larger, the tibia uniformly black, the 
orifice of the metastethium differently shaped. 


4, Macrotrachelia thripiformis, n. sp. (lab. XIX. fig. 17, ¢.) 


Moderately elongate, narrow, subfusiform, clothed with a few scattered hairs, shining, the elytra opaque, the 
vittes excepted; black, the elytra with a streak or space along the inner edge of the clavus and a vitta on 
the outer portion of the corium extending from the base downwards flavo-testaceous, the membrane 
broadly hyaline externally, the third antennal joint entirely ochreous or flavous, the tarsi flavo-testaceous 
at the base; the pronotum and scutellum with very fine scattered silvery pubescence, the elytra with fine 
lines of glistening golden pubescence on the clavus and outer portion of the corium, the two lines on the 
corium uniting posteriorly and forming a broad stripe down the cuneus. Head smooth ; the eyes large, 
round, and coarsely faceted in the male, small and finely faceted in the female ; antenna moderately long, 
joints 1 and 2 rather stout, 2 becoming much thicker towards the apex, 3 and 4 more slender, 2 more

than twice as long as 1, 3 and 4 equal in length, each much shorter than 2. Rostrum about reaching 
the anterior coxe. Pronotum slightly hollowed at the sides, the anterior lobe almost smooth, the posterior 
lobe transversely rngulose. Orifice of the metastethium transverse, curving forward externally. 
Length 33-33 millim. (¢ 92.) 


Hab. Guatemaa, San Gerénimo, Las Mercedes (Champion). 


Six specimens. Very like M. nigronitens, but differing from it in having the third 
antennal joint entirely pale and the elytra distinctly vittate. . The eyes in the male are 
very large and separated bya space not much wider than the produced anterior portion 
of the head; those of the female are small and very little more than half the width of 
the interocular portion of the head.

Moderately elongate, narrow, subfusiform, clothed with a few scattered hairs, shining, the elytra opaque, a 
narrow space down the outer part of the corium and the outer edge of the cuneus excepted ; black, the 
elytra sometimes with a narrow piceous or fusco-testaceous vitta on the outer part of the corium extending 
from the base downward, the membrane broadly hyaline externally, the basal half of the third antennal 
joint ochreous, the tarsi usually testaceous at the base; the posterior lobe of the pronotum and the 
scutellum with very fine scattered silvery pubescence, the elytra with fine lines of glistening golden 
pubescence on the clavus and outer portion of the corium. Head, eyes, antenne, and rostrum as in 
M. thripiformis. Pronotum hollowed at the sides, the anterior lobe smooth, the posterior lobe trans- 
versely rugulose. Orifice of the metastethium transverse, curving forward externally. 

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 
a little scattered silvery pubescence. Head smovth, the eyes small; antennz stout, rather short, joints 3 
and 4 more slender than 2, 3 twice as long as 2 and slightly shorter than 4. Rostrum nearly reaching 
the anterior coxe. Pronotum hollowed at the sides, the anterior lobe smooth, the posterior lobe trans- 
versely rugulose. Orifice of the metastethium transverse, becoming a little curved outwards.

$22 HEMIPTERA-HETEROPTERA. 


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 ;—

* In addition to these, we possess an example (<¢ ) of another species, from Mexico city (H. H. Smith), but 
it is too immature for description. In this insect the entire upper surface is testaceous and shining (as in 
A. antevolens, B. White) ; the antenne are much longer than the head and pronotum united, with the apices 
of the second and third joints, and the fourth entirely, black; and the membrane has three pale longitudinal 


streaks.

Very like A. nigripes, but narrower, the elytra lighter in colour, with lines of 
glistening golden pubescence, the membrane pale, with a dark patch in the middle, 
the antenne with the basal half of the second joint, as well as the base of the third, 
ferruginous, the legs paler. The types have been examined.. 


3. Anthocoris nigripes. 
Anthocoris nigripes, Reut. Monogr. Anthocorid. p. 69°. 


Hab. Mexico (Bilimek, in Mus. Vind. Cas. 1). 


Distinguishable by its almost entirely black legs and antenna, the latter with the 
base of the third joint * ferruginous, and opaque, fuscous elytra, the elytra with lines 
of glistening silvery pubescence. The two specimens belonging to the Vienna Museum 
‘have been seen. 


4, Anthocoris variipes, n. sp. (Tab. XIX. fig. 23 +.) 


Narrow, black or pitchy-black, the venter sometimes rufous along the middle ; the elytra fuscous or sordid 
ochreous, with the margins of the embolium ochreous, the cuneus sometimes blackish, the membrane 
uniformly smoky; the antenne usually with the second joint testaceous or ferruginous to near the apex, 
in some specimens entirely black ; the legs testaceous or ferruginous, usually with the tibiz at the base 
and apex, and the tips of the tarsi, more or less infuscate, the femora sometimes blackish to near the 
apex ; opaque, the ante-ocular portion of the head, the neck, the scutellum in front, and the venter 
shining, clothed with a very sparse, fine, golden or silvery pubescence, which is subserially arranged on 
the elytra. Head finely rugulose between and behind the eyes, the latter a little larger in the male than 
in the female; rostrum reaching the anterior coxe ; antennee moderately long, joint 2 nearly three times 
as long as 1 and one-half longer than 3, 3 and 4 equal in length. Pronotum rugulose, transversely 
depressed on the middle of the disc, the sides slightly sinuate. Elytra parallel to the apex of the embolium, 
smooth, the membrane with the outer nervure only distinct. 

Length 3-34, breadth 1-1 millim. (¢ 9.) 


Hab. GuaTEMALA, Quezaltenango, Totonicapam, Cerro Zunil 5000 to 10,000 feet 
(Champion). 

Twelve examples, three of which have the antenne entirely dark; the one from 
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. 


* Not the base of the second, as stated by Dr. Reuter. 
+ The elytra are more parallel-sided than represented by our artist. 


ANTHOCORIS. 325 


5. Anthocoris variicornis, n. sp. 


Comparatively broad, black, the elytra fuscous, with the margins of the embolium ochreous; the antenns 
with the basal two-thirds of each of the joints 2 and 3 ochreous; the legs ochreous, with the apices of 
the tibiz and tarsi, and the femora to near the tip, black ; opaque, sparsely clothed with a very fine 
golden pubescence, which is subserially arranged on the elytra. Head and pronotum rugulose, the inter- 
ocular portion of the former nearly twice as wide as one of the eyes, the latter small, the pronotum not 
sinuate at the sides; antenne comparatively short, joints 1 and 3 subequal in length, 3 about twice as 
long as 1, 4 longer than 3. Elytra as in A. variipes. 

‘Length 33, breadth 13 millim. (@.) 


Hab. Panama, Volcan de Chiriqui 8000 feet (Champion). 


One mutilated specimen. It is perhaps an extreme form of A. variipes, but the 
relative lengths of the joints of the antenne are different. 


6. Anthocoris rufotinctus, n. sp. (Tab. XIX. fig. 24.) 


Narrow, nigro-piceous, the posterior lobe of the pronotum rufo-testaceous, the elytra sordid ochreous, with the 
apical half of the corium infuscate and the outer edge of the cuneus rufescent, the membrane uniformly 
smoky; the antenne with joints 1 and 4 fuscous, 2 rufo-testaceous, and 3 ochreous ; the legs piceous, the 
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 
membrane with the outer nervure only distinct. 

Length 21, breadth Z millim. (¢.) 


Hab. Guatemaa, Cerro Zunil (Champion). 


One specimen. Much smaller than J. variipes, the head more exserted, the antennz 
not so stout, and with the second and third joints entirely pale, the pronotum not 
sinuate at the sides and with the posterior lobe rufo-testaceous, the cuneus rufescent 
externally. 


7. Anthocoris dentipes, n. sp. (Tab. XIX. fig. 25, ¢.) 


Narrow, deep black, the shoulders of the elytra obscure ferruginous, the tarsi testaceous at the base ; opaque, 
the head and the anterior half of the scutellum shining, clothed with a widely scattered golden pubescence, 
which is serially arranged on the elytra, and also with a few long, erect, blackish hairs. Head smooth ; 
the eyes large in the male, much smaller in the female; antenne rather short, stout, joint 2 thickening 
outward and about two and one-half times the length of 1, 3 longer than 1 and a little shorter than 4. 
Pronotum slightly depressed on the disc, rugulose, rounded at the sides in front. Elytra parallel to the 
apex of the embolium, smooth, the membrane without distinct nervures. Anterior femora in the male 
armed with a short tooth on the lower side towards the apex. 

Length 25-27, breadth 4-1 millim. (¢ 2.) 


Hab. Panama, Tolé, Pefia Blanca (Champion). 


Two specimens. The male (which is ‘ina mutilated condition) has the anterior 
femora armed with a short tooth beneath, exactly as in the Brazilian Zopherocoris

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

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.

Entirely opaque, clothed with a fine scattered silvery pubescence, which is serially arranged on the elytra, the 
antenne and legs finely pubescent; black, the elytra with the embolium and cuneus at the sides, the inner 
apical angles of the corium, and the transverse plica, obscure ferruginous, and the membrane fuscous; the 
second antennal joint, the tibie, and the base of the tarsi ferruginous, the third antennal joint piceous. 
Pronotum with the sides obliquely converging from the base, the two lobes separated by a faint transverse 


depression, the surface transversely rugulose. Elytra with indications of very fine, shallow, obsolete 
punctures.

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.

CARDIASTETHUS. 331 


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. 

Length 24-3 millim. (¢ 2.)

Var. Above and beneath testaceous, the elytra more sparsely punctured. 


Hab. GvateMata, San Geronimo (Champion). 


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

them by the very deeply emarginate base of the pronotum, the transversely sulcate 
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.

Cardiastethus limbatellus, Reut. Monogr. Anthocorid. p. 138 *. 


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.

more or less infuscate; the rostrum (the base excepted) and legs testaceous. Head, antenna, and 
rostrum as in C. limbatellus, Pronotum much narrowed anteriorly, feebly rounded at the sides, the 
posterior lobe deeply depressed on the dise in front and also faintly rugulose, the base very deeply 
emarginate. Scutellum and elytra as in C.limbatellus. Orifice of the metastethium very long, extending

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 :— 


Elytra black or fuscous, with the shoulders distinctly ochreous. 
Body ovate: length 8 millim.. . . 2... 1... Suleifer, Stal. 
Body oblong, narrow: levgth not more than 2 millim. . . . . . canaliculatus, n. sp.

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. 

Length 13-2 millim. (d @.) 


Hab. GuaTeMaA, Pantaleon (Champion); Panama, Bugaba, San Feliz (Champion).

3. Solenonotus nigromarginatus, n. sp. (Tab. XIX. fig. 31.) 


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.)

Dr. Reuter includes this genus in his division Xylocoraria, which are without a 
hamus in the cell of the wings; but in the American species, as well as in one of the 
European forms, the hamus is often present. Four species are known, three of which 
are Palearctic.

Of this family a single species only is known to me from Central America. None 
appear to have been recorded as yet from within the limits of the United States. Nine 
species, belonging to six genera, have been noticed by Prof. Uhler from the Antillean 
islands of Grenada and St. Vincent, and it is therefore probable that others will 
eventually be found on the Isthmus of Panama.

1. Ceratocombus panamensis, n. sp. 


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 
figure of C. brasiliensis (Monogr. Ceratocomb. tab. fig. 3 a).

This universal pest was observed by me in various places in Central America, but 
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

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, 

Length 4-5, breadth 2-21 millim. (¢ 2.)

Three specimens. Very like S. sulcicollis, but. darker and a little more elongate, the 
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. 

Length 33, breadth 14 millim. (<¢.)

and the elytra entirely opaque. In its general shape it is shorter and relatively broader 
than any of the other Central-American members of the genus. The margins of the 
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

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. 
Length 33-4, breadth 13-2 millim. (¢ 9.) 
Hab. Guatemata, San Gerénimo and Guatemala city (Champion); Panama, Volcan

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.

eyes, the pronotal margins, except at the base and apex, an oblong spot on the clavus near the base and 
another near its apex, the costal area of the corium from the base to about the middle, a spot on the disc

with the nervures fuscous or blackish; the antennz black, with the basal joint to near the tip, and a 
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 
fuscous. Head, pronotum, and scutellum very finely rugulose ; ocelli narrowly separated ; antenne long 
and slender, finely pubescent, joints 2 and 3 subequal in length, 4 slightly shorter than 3; pronotum 
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. 


10. Salda abdominalis, n. sp. (Tab. XX. fig. 10.) 


Ovate, opaque, the upper surface clothed with a very short, fine, decumbent golden pubescence; black, the 
head in front, two spots between the eyes, the pronotal margins, excepting at the base and apex, the costal 
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, 
and legs flavo-testaceous, the tibice and tarsi annulated with fuscous; the pleura with one or two flavous 
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. 
Legs finely pubescent, the tibize with fine scattered seta.

This second main division of the Rhynchota-Heteroptera includes all those forms in 
which the antenne are very short and inserted on the underside of the head, often 
concealed in grooves or fovee. With the exception of the species of the first two 
families, which live on the banks of streams, &c., they are all aquatic. The whole 
of the preceding families dealt with in this volume, and in Vol. I., belong to the

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,

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.

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 
abdomen with bluish-white pubescence. Face densely rugulose, not carinate between the eyes, the latter 
moderately large. Pronotum, scutellum, and elytra sparsely, indistinctly punctate; pronotum about 
one-half wider at the base than at the apex, the sides slightly arcuate, the anterior and lateral angles 
rounded, the latter not projecting beyond the elytra; elytra somewhat rounded at the sides ; nervures

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.

(Champion). 


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.

We possess three specimens of this species from within our limits, and two others 
from Costa Rica belonging to M. Montandon have been seen. It has the pronotum 
narrower than the elytra, with the sides bisinuate, the lateral angles subtruncate and 
strongly oblique on their anterior edge. Guérin’s figure, it may be noted, represents 
the base of the pronotum as nearly straight, whereas in our insect it is strongly 
trisinuate.

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.

This peculiar genus includes seventeen described species, seven of which are American, 
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 
a Costa Rican male and the Purula female.

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. 
Cryphocricos, Signoret, Rev. et Mag. Zool. 1850, p. 290. 
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. 


* Montandon, who has redescribed it (Verh. zool.-bot. Ges. Wien, 1897, p. 7), gives “Chili” as the 
locality. 


CRYPHOCRICUS.—AMBRYSUS. 355 


1. Cryphocricus macrocephalus. (Tab. XXI. figg. 2, 2a, 2; 2, antenna.) 
Cryphocricus macrocephalus, Mont. Bull. Mus. Paris, 1897, p. 124 ‘ 
Hab. Mexico, Cuernavaca in Morelos (H. H. Smith); Guatemata, Alta Vera Paz 
(Bocourt, in Mus. Paris.'). 


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.)

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.

flab. Mexico !~3 (Mus. Vind. Ces.). 


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. .

Borborocoris, Stal, Ofv. Vet.-Ak. Férh. xviii. p. 202; Enum. Hemipt. v. pp. 142, 146. 


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.

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). 


Subfam. VAUCORIN. 


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).

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. 
Hemipt. viii. p. 175).

(1871) (nomen preocc.). 
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.

We have not received a specimen of this insect from within our limits. Two females 
from Mexico, belonging to the Vienna Museum, have, however, been examined. 


* The presence of two small hairy papille in this sex has been noticed by Miss F. W. Slater (Amer. Nat.

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.

The second and third antennal joints have each a moderately long process. We

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.

Of this species we possess six specimens from Mexico. They vary somewhat in the 
sculpture of the elytra, the single example from the Rio Mescales being more rugose 
than the others. Mayr! originally gave as localities “ California and Mexico,” but 
he subsequently stated ? that the last-mentioned habitat was incorrect.

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.

They are all of very large size, some specimens of B. grande measuring upwards of 
four inches in length (109 millim.). The sexual characters (as well as those of the 
allied North-American genus Benacus) have been described and figured by Riley (Proc. 
Ent. Soc. Wash. iii. pp. 83-88, figg. 4, 5); he says that the only external indication of 
the sexes is, that the last ventral segment of the abdomen is entire in the male, and 
slightly notched and bimucronate at the apex in the female. B. colossicum belongs to 
Stal’s section Amorgius, the others to Belostoma, s. str.

Several species of this well-known genus inhabit Central America, but one only, 
N. mexicana, is well represented in our collection, few travellers, myself included, 
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 @).

Notonecta montezuma, Kirk. Trans. Ent. Scc. Lond. 1897, p. 402°. 


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.

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. 
Calif. Acad. Sci. (2) iv. p. 293 (1894)].

Moderately elongate, rather slender, smooth, shining; head and pronotum sordid white, the latter sometimes 
black with the anterior portion whitish and the cariniform elevations rufescent; the scutellum black or 
fuscous, with the apex more or less pale; the elytra varying in tint according to the predominance 
of the black or testaceous colour beneath, sometimes with several red spots at the humeral angles, 
appearing entirely whitish in pale specimens ; the under surface more or less testaceous, the venter black, 
with the median carina, the terminal segment, and some spots on the connexivum flavescent; antennze 
and legs testaceous, the four anterior tibie externally, and the posterior tibiee beneath, each with a more 
or less distinct darker streak down the middle, the hind tibie and tarsi with blackish hairs. Head (with 
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.

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.

ANISOPS.—CORIXA. 375 


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 middle of the eyes. Length 3°; of an inch.”

the surface crossed by about fourteen slender brown lines; the elytra with very slender, 
short, dark brown lines arranged in four uneven longitudinal series, the clavus with 
broad, straight, and almost complete yellow bands at the base; the frontal depression 
of the male large and ovate; the pale of the male short, broad-cultrate, acute at thie

3. Rather short and broad, comparatively robust, shining ; pale testaceous, the eyes black, the pronotum 
with 7—9 transverse black lines, which are narrower than the pale interspaces ; the elytra nigro-fuscous, 
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.

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.

5. Corixa maria, n. sp. (Tab. XXII. figg. 20, 20a, 3.) 


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.

oblique black streak on either side of it posteriorly showing through ; the elytra with the clavus, except 
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

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 chief characters of this species are given as follows :—“ Frontal fovea suboval, 
rather shallow, extending to about one-third of the length of the eyes. Pale long, 
narrow, cultrate, with about thirty-six small, rounded, blunt teeth. Strigil rather 
large, almost square, with about eight rows of teeth. Intermediate tibie one-fourth 
longer than the tarsi, which are about one-seventh longer than the claws. Pronotum 
with 11-12 yellow lines. Pronotum, clavus, and corium feebly rastrate. Length

9. Moderately elongate, broad, robust, shining ; testaceous, the head with a f\-shaped mark beneath and a 
narrow space before the labrum piceous, these markings connected in one specimen ; the pronotum with 
from 12-16 transverse black lines, the lines becoming broader towards the apex; the elytra nigro-fuscous 
or black, crossed by many undulate flavescent lines, which are but little interrupted on the clavus and 
corium, the markings on the membrane more irregular, the corium usually with a conspicuous pale lunate 
mark at the apex and a space in front of it darker than the rest of the surface, the marginal area with 
the apex, a transverse mark at the middle, and sometimes a space below the base, more or less black ; the 
venter and under surface in great part black ; the anterior tarsi or tibia at the apex externally, the apices 

_ of the intermediate femora, tibiew, and tarsi, and the apex of the hind tarsi broadly, more or less infuscate 
or black. Head with two widely separated, coarsely punctate sulci on the vertex, and some punctures near 
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.

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

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,

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).
