Genus OPISOXESTUS Ashmead 
Opisoxestus ASHMEAD, Proc. U. S. Nat. Mus., vol. 23, p. 40, 1900. (Genotype, 
O. ferrugineus Ashmead, monobasic. ) 
The single female specimen on which this genus was based lacks 
the head, right hind wing and hind leg, and part of the right front 
leg. It is a species of Joppidium in which the only sculpture con- 
sists of striation and foveolation in the pronotal scrobe and along 
the sutures and furrows. On the label the generic name is spelled 
“Onpisthoxestus”, which makes evident Ashmead’s intention to derive 
the name from émofe (behind) and feords (polished) in reference
