220 HEMIPTERA-HETEROPTERA. 
the ochreous markings form an elongate, X-shaped mark, instead of a single broad 
elongate vitta as in R. flavovittatus. LR. bifurcatus closely resembles various species of 
Leogorrus (L. fasciatus &c.). 
Stal’s type (2 ) of &. flavovittatus has been examined.

Two specimens of this species were found by myself in Chiriqui, both females, like 
the type, which is now before me. A. arciger differs from all the other Central-American 
members of the genus in the densely cinereo-pubescent head and anterior lobe of the 
pronotum. The elytra have a rather large spot below the base (occupying the apex of 
the clavus and a space on the adjoining portion of the corium), a transverse curved 
fascia before the middle of the membrane, and a rounded spot at its apex, sordid 
white. The pronotal sulci are very shallow.

A genus containing about a dozen described forms, two or three only of which are 
American, these latter being probably nothing more than colour-varieties of one 
species.
