"2J., 6-4-6-8 mm. Scale higher and more convex transversely than 

 in the typical Ruspolii. The blunt, bristly, white hairs more plentiful, 

 especially on the abdomen. The latter with a sparse silvery pubes- 

 cence, as in Grandidieri, and with a glabrous median longitudinal 

 line. Pit-like punctures on the head as in the type, feeble or absent 

 posteriorly. Thorax short, very wide in front, narrowed to a point 

 behind. The dorsum of the epinotum is straight and much shorter 

 than the declivity. Black, dull ; antennae, legs and mandibles 

 bright red ; cheeks in front reddish. Otherwise just like Ruspolii.''''

The type of the species is West African, (Angola). It is represented 

 in our region by four forms which, like the type, have the abdomen 

 shining, feebly rugulose and very sparsely pubescent.

"Differs from the type of the species by the erect hairs on the 

 abdomen being much finer, not thicker, or even a little thinner than 

 the decumbent pubescence ; the latter are, however, thicker and 

 whiter than in Olivieri." Pretoria, (Simon).

 pit-like punctures on the head remain sharply defined and large right 

 up to the posterior margin. Pronotum rounder and convex, hardly
