but differs in the sculpture of the head, and especially of the 

 prothorax, which is only asperous in the centre of the posterior 

 part instead of being granular. 



It is also uncommonly like 0. bidens, Oliv., from Senegal and 

 it seems to take its place in Central East Africa. Its extreme South 

 African limit would seem to be Beira (Mozambique).

" Opaque, black, briefly pubescent on the upper side. In the $ 

 the head is rugose, the frontal part asperate punctate, the clypeus 

 truncate, the front has a strong arcuate carina and the vertex a 

 strong, but little arcuate one situated a little past the eyes ; pro- 

 thorax closely granulate, but little densely asperate punctate behind, 

 smooth along the basal margin and having in the middle of the disk 

 a longitudinal smooth, sub-cariniform line, transversely bi-callose in 

 the middle of the anterior part ( $ ) and sub-callose on each side, 

 sides sinuate near both the anterior and the posterior angles, base 

 marginate, regularly rounded; elytra moderately finely striate, 

 intervals plane, moderately densely granulate, the granules not 

 disposed in order ; pygidium moderately densely punctate, basal 

 carina strongly angular in the centre ; antennal club black.

Greatly resemble 0. cameloides (urus, Har.), which differs, how- 

 ever, by the sinuate epistoma, the frontal part covered with 

 moderately closely set asperities, the prothorax more clearly and 

 less densely granulate, without cariniform line in the middle of the 

 disk, the base, which is not regularly rounded but is slightly 

 angular in the centre, the sides, which are not sinuate near the 

 anterior angles, and the intervals of the elytra, the granules of 

 which are much more remote, and lastly the size, which is 

 larger."
