semicircular, not emarginate at tip, no frontal carina ; prothorax 

 moderately convex, marginate all round, not quite round in the 

 median part of the base, covered with round, very closely set 

 punctures, which are smaller in the centre than on the sides ; elytra 

 ampliato-ovate, narrowly geminato-striate, striae punctulate, 

 intervals plane and very finely aciculate, second interval a little 

 wider than the third , humeral callus very distinct ; pygidium 

 vaguely punctulate ; metasternum punctate, median longitudinal 

 impressed line distinct. 



Male : Posterior part of vertex raised in a high vertical lamina, 

 broadening obliquely from the sides, slightly sinuate in the middle 

 at apex, and reaching as high as the median lobe of the prothorax 

 which projects above the retuse anterior part, is slightly emarginate 

 in the middle, and nearly reaches the cephalic transverse carina ; 

 anterior tibiae nearly straight at apex, angular but not spinose 

 inwardly at tip, and with the apical spur long, straight, slightly 

 curved outwardly, they are strongly quadri-dentate outwardly. 



Female : Basal part of the head with a very slightly raised arcuate 

 carina ; prothorax not retuse nor lobate in front. 



The description of the male is made from one of Fahroeus' co- 

 types.

Harold, owing to the presence of a lateral cavity on the side 

 of the prosternum, places this species among Caccobius. This 

 peculiarity is, however, restricted to the male, and occurs also, 

 although in a more or less distinct form, in other South African 

 Onthophagi (0. pusio, merus, obtusus, &c.), and in a lesser degree in 

 0. histerinus, which on account of the peculiar shape of the anterior 

 tibiae of the male I have, with 0. anomalus retained in the genus 

 Caccobius.
