64 HEMIPTERA-HETEROPTERA. 
The scutellum is somewhat long, triangular, and narrowed at the apex; pronotum 
deflexed anteriorly, membrane with longitudinal nervures. These are merely superficial 
characters, given here to separate it from the preceding and following genera, some 
closely-allied ones not being found in the Central-American fauna.

hemlock and grape.

TRICHOPEPLA. 
Trichopepla, Stal, Ofv. Vet.-Ak. Férh. 1867, p. 528. 
Two species are described, both Nearctic forms; one is here included in this 
fauna. 
The rostrum extends to the posterior coxe; the antenne are short, the first joint 
not reaching the apex of the head. Pronotum convex, deflexed anteriorly ; lateral 
margins slightly reflexed. The body is pilose; and, as Uhler truly remarks (Proc. Bost. 
Soc. Nat. Hist. vol. xix. p. 374), “it is the nearest North-American representative of 
the African genus Agonoscelis.”
