100 HEMIPTERA-HETEROPTERA. 
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. 
Length 63-84, breadth 24-34 millim. (6 9.) 
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.
