98 HEMIPTERA-HETEROPTERA. 
post-ocular portions dilated laterally into a short spine and obliquely converging thence to the base; 
antenne rather slender, joint 2 a little shorter than 1, 3 nearly one-half longer than 2 and longer than 1, 
4 slightly shorter than 2, ovate. Pronotum feebly emarginate at the base, strongly constricted at the 
sides ; the anterior portion dilated on each side anteriorly into a broadly rounded lobe, which is subangular 
in front, the callosities each with a short indistinct ridge; the posterior portion much broader than the 
anterior portion, with the sides subangularly dilated anteriorly, rounded in front, and subparallel and 
crenulate behind. Scutellum transversely rugose and with an indistinct median ridge. Corium rounded 
at the apex. Connexivum broad, gradually narrowing from the base of the fifth segment; the sixth 
segment rounded at the sides in both sexes—in the female arcuate-emarginate at the apex, leaving the 
first genital segment rather broadly exposed, the latter with two broad, rounded, prominent lobes. 
Terminal genital segment of the male large, cordate; the lobes of the first genital segment long and 
narrow. Beneath rugulose, the venter and connexivum with rows of smooth callosities, the venter flattened 
and with a row of small, oval, smooth, depressed spots down the middle. 
Length 7-72, breadth 23-33 millim. (3 2.) 
Hab. Guatemaa, Purula in Vera Paz, Capetillo (Champion). 
A female from Purula and a male from Capetillo, the latter unfortunately having 
the head broken off. Differs from the allied forms in the shape of the pronotum, the 
spotted connexivum (resembling that of some species of Hesus), &c. 
8. Brachyrrhynchus constrictus, n. sp. (Tab. VII. fig. 2, ¢.) 
Oblong, broad, nigro-piceous above, black beneath, the tarsi obscure testaceous, the membrane fuscous; the 
upper surface conspicuously granulate, the bare spaces on the connexivum almost smooth, and clothed 
with short, curled, rusty-brown hairs; the legs and antenne shortly pubescent. Head (exclusive of the 
apical process) transverse, somewhat rounded at the base; the apical process about reaching the middle 
of the first antennal joint, slightly emarginate at the tip; the spiniform antenniferous processes divergent, . 
rather short ; the post-ocular portions dilated laterally into an acute spine, which extends to a little beyond 
the eyes, obliquely converging behind; antenne slender, with a stouter basal joint, joint 2 shorter than 1 
and slightly longer than 4, 3 longer than 1, 4 piriform. Pronotum feebly emarginate at the base, strongly 
constricted at the sides, and emarginate in front, the margins crenulate; the anterior portion dilated on 
each side into a raised, broadly rounded, anteriorly projecting lobe, the two inner callosities with 
indications of a short ridge; the posterior portion much wider, rounded at the sides anteriorly and parallel 
behind. Scutellum conspicuously granulate. Corium narrowly rounded at the tip, obliquely truncate 
within. Connexivum broad, with the outer apical angles of the segments slightly projecting, obliquely 
narrowing from the base of the fifth segment; the sixth segment subangularly produced at the apex in 
the male, obtuse in the female. First genital segment narrowly exposed in the female, with two short 
rounded lobes. Terminal genital segment of the male cordate; the lobes of the first genital segment 
long and narrow. Venter somewhat convex, with irregular smooth shining spaces, the intervening parts 
dull, sparsely granulate, and with the depressions here and there covered by an ochraceous incrustation, 
the segments 1-5 each with a smooth opaque spot in the middle behind. 
Length 64-72, breadth 27-33 millim. (d 9.) 
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.
