96 HEMIPTERA-HETEROPTERA. 
slender, with a stout basal joint, joints 1 and 3 subequal in length, 2 much longer than 4, 4 about half 
the length of 3, piriform. Pronotum feebly emarginate at the base, the lower anterior angles somewhat 
prominent, the surface coarsely, irregularly granulate, transversely wrinkled at the sides; the anterior 
portion subparallel, feebly emarginate or subtruncate in front, the anterior angles more or less rounded, 
the two inner callosities rather prominent ; the posterior portion much wider than the anterior 
portion, rounded at the sides anteriorly and parallel behind, the margins crenate. Scutellum transversely 
wrinkled. Corium arcuate-emarginate within, obliquely truncate at the apex, the nervures and hind 
margin granulate. Connexivum broad, very finely punctured, narrowing from the base of the fifth 
segment; the sixth segment in the female transversely raised before the apex, which is broadly emarginate, 
leaving the first genital segment narrowly exposed, the latter with two short lobes. The genital lobes short 
in the male. The under surface closely, finely punctate (rugulose beneath the incrustation); the venter 
somewhat convex, the segments each with a small, oval, depressed spot in the centre. Rostrum not 
extending beyond the base of the head, the groove narrowing and closed behind. 
Length 9-10/, breadth 34-32 millim. (¢ 2.)

One male and four females were obtained in Chiriqui. Differs from all the other 
Central-American species in the almost glabrous body, the surface above (the corium 
excepted) and beneath almost covered by a thin greyish-ochraceous incrustation. It 
approaches Cinyphus, but has the pronotum less deeply emarginate at the base.

@. Oblong-ovate, broad, pitchy-black or nigro-piceous, the base and apex of the antenne and the tarsi 
ferruginous ; the membrane lurid, with the nervures fuscous ; the upper surface granulate, the connexivum 
rugulosely punctured, and somewhat thickly clothed with short, curled, decumbent, rusty-brown hairs, 
these being conspicuous along the apical margins of the connexival segments and on a series of semi- 
circular elevations extending along each side of the dorsum of the abdomen; the under surface in great 
part covered by a thin pallid ochraceous incrustation, the sides with a few very short curled hairs. Head 
subquadrate; the apical process broad, about reaching the middle of the first antennal joint, unemarginate 
at the tip; the antenniferous processes stout, terminating in a short spine in front, slightly divergent; the 
post-ocular portions short, and dilated laterally into a short spine; antenne rather slender, with a stout 
basal joint, joint 2 a little shorter than 1, 3 considerably longer than 1 and nearly twice as long as 4, the 
latter piriform. Pronotum feebly emarginate at the base, constricted at the sides, the margins crenulate ; 
the anterior portion rounded at the sides, the callosities each with a short longitudinal ridge; the posterior 
portion much wider, with the sides rounded anteriorly and subparallel behind. Scutellum transversely 
wrinkled, slightly raised along the middle, and with a flattened tubercle at the base on each side. Corium 
rounded at the apex. Connexivum broad, narrowing from the base of the fifth segment; the sixth 
segment abruptly narrowed, feebly emarginate behind, leaving the first genital segment narrowly exposed, 
the latter with two short lobes. Venter feebly convex, sparsely and rather finely punctured, the segments 
1-5 each with an oblong smooth spot in the middle.
