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 
Dr. Bergroth. 
12. Brachyrrhynchus latus, n. sp. 
2. Ovate, broad, nigro-piceous, the tips of the antenne and the tarsi ferruginous, the membrane fuscous, with 
two obscure luteous marks at the base; the upper surface granulate, the connexivum rugulose, and clothed 
with excessively short, scattered, ochraceous hairs; the antenng (the tip excepted), femora, and tibize 
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 
black; the upper surface granulate, the connexivum rugulose, and clothed with extremely short rusty- 
brown hairs; the legs and antenne finely pubescent. Head (exclusive of the apical process) transverse, 
somewhat rounded behind; the apical process stout, convex, extending to near the apex of the first 
antennal joint, slightly notched at the tip; the spiniform antenniferous processes acute, short; the post- 
ocular portions rather broad, dilated laterally into an acute spine, which extends outwards as far as the 
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 
ridge. Corium rounded at the apex. Connexivum gradually and obliquely narrowing from the base of 
the fifth segment; the sixth segment rapidly and obliquely narrowed, with the apical angles produced 
into a short rounded lobe. Terminal genital segment cordate; the lobes of the first genital segment 
moderately long. Beneath rugose, dull; the venter somewhat convex, the segments each with a smooth 
spot in the middle. 
Length 62, breadth 2} millim.
