White’s description is drawn up from a female spe- 
cimen. The S differs in having a narrow black 
margin to the vitreous central part, which is quite con- 
tinuous, except for a small space at the apex. The elytra 
are a little shorter than the abdomen, and dehiscent from 
the middle ; the femora are abruptly and strongly clavate ; 
the antennae are but very slightly thickened towards the 
apex, almost filiform. The species, however, is very 
closely allied to 0. fasciata, in which the antennae are 
very strongly thickened. It is still more closely related 
to 0. triliturataj in which the hind femora have no brush- 
like hairs.

The antennae from the fifth joint are dilated, com- 
pressed, and serrate. The elytra are shorter than the 
abdomen, dehiscent, and sublinear.
