The female has simple antennae, and the elytra have a short 
longitudinal impression at the sides; the male of this species 
is like the female of the preceding one, devoid of the thoracic 
foveas, to be found in most of its allies, all inhabitants of 
Africa; the structural characters peculiar to the genus are 
all present in the Abyssinian forms here described.

black or piceous; head and thorax very finely rugose; elytra
