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. 
6. Brachyrrhynchus longipilis, n. sp. (Tab. VI. figg. 29, ¢; 29a, antenna.) 
Ovate, rather broad, nigro-piceous or black, the membrane obscure luteous round the apex of the corium; the 
upper surface granulate, the connexivum very finely rugulose, and sparsely clothed with very fine hairs, 
these being erect or suberect on the head and pronotum ; the antenne and legs also with rather long, fine, 
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. 
Length 74-8, breadth 3}-33 millim. (¢ 9.) 
Hab. Mexico, Xucumanatlan and Omilteme in Guerrero, 7000 to 8000 feet 
(H. H. Smith). 
One male and three females. Very like B. neotropicalis, but more ovate in both 
sexes, the hairs on the upper surface, antenne, and legs longer, finer, and erect, the 
connexivum finely rugulose. The comparatively long and very fine hairs are particularly 
noticeable on the head, antenne, and legs, this character separating the species from 
all the other Central-American members of the genus. The insect is unknown to 
Dr. Bergroth. 
7. Brachyrrhynchus maculiventris, n. sp. (Tab. VII. figg. 1, 9; 1a, 
antenna.) 
Oblong-ovate, moderately broad, nigro-piceous or ferrugineo-fuscous, the tips of the antenna, the coxe, and 
tarsi ferruginous, the connexivum and venter much spotted with ochraceous or ferruginous, the membrane 
lurid, with blackish nervures; the upper surface finely granulate, the connexivum finely punctured and 
with smooth rounded spots, the elevated portions clothed with extremely short rusty-brown hairs; the 
antenne and legs shortly pubescent. Head subquadrate; the apical process reaching to the middle of the 
first antennal joint, emarginate at the tip; the spiniform antenniferous processes acute, divergent ; the
