BRACHYRRHYNCHUS. 99 
9. Brachyrrhynchus regularis, n. sp. (Tab. VII. fig. 8, 3.) 
Oblong-ovate, rather broad, fuscous, the antenne and tarsi obscure ferruginous, the outer apical angles of the 
connexival segments ochraceous, the membrane lurid, with dark nervures; the upper surface rather finely 
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 
portion much wider than the anterior portion, rounded at the sides anteriorly and parallel behind. 
Scutellum with a median ridge and also raised on each side in front. Corium narrowly rounded at the 
tip. Connexivum moderately broad, rounded and gradually narrowing from the base of the fifth segment, 
the margins uninterrupted and minutely crenulate. Terminal genital segment of the male large, very 
broad, transversely cordate ; the lobes of the first genital segment stout and rather short. Terminal 
genital segment of the female truncate at the apex ; the lobes of the first genital segment short. Beneath 
rugulose; the venter somewhat convex, the segments each with a smooth spot in the middle. 
Length 7-71, breadth 3 millim. (¢ @.) 
Hab. GuatemaLa, El Tumbador 2500 feet (Champion: ¢); Costa Rica, Turrialba 
(Biolley: 2). 
Two males from the Pacific slope of Guatemala, and a single female from Costa Rica, 
the latter communicated by Dr. Bergroth. Distinguishable by the very long post-ocular 
spines, in connection with the moderately sinuate and rather coarsely crenulate sides 
of the pronotum, the evenly rounded sides of the connexivum towards the apex in 
the male, and the very broad terminal genital segment in this sex. It approaches 
B. granuliger, Stal, from Brazil, the type (¢ ) of which is before me, but differs from 
that species in the evenly rounded sides of the connexivum, the less coarsely granulate 
upper surface, the short genital lobes, &c. 
10. Brachyrrhynchus neotropicalis, n. sp. (Tab. VII. fig. 4, ¢.) 
Oblong-ovate (9), slightly widened behind (¢), rather broad, varying in colour from black with the 
connexivum piceous to almost entirely fusco-ferruginous; the membrane blackish or fuscous, more or 
less marked with obscure luteous round the apex of the corium; the upper surface granulate, the 
connexivyum comparatively smooth, and clothed with scattered, very short, curled, rusty-brown hairs; the 
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
