0. patricius, Per., Cat. i., p. 228. 



d'Orbigny has established this synonymy (Ann. Soc. Ent. Fr., 1905, 

 p. 532). The species was first described from Angola. 



Onthophagus marshalli, d'Orbign. 



This species is so closely allied to 0. granulum, d'Orbigny, that I 

 verily believe the two are merely the different sexes of one species. 

 Moreover, my two examples of 0. granulum and 0. marshalli were 

 found the same day and in the same locality. The example identified 

 by d'Orbigny under the name of marshalli differs from granulum, 

 also identified by d'Orbigny, in having the clypeus more broadly and 

 more arcuately scooped in front with the angles of the incision 

 sharper, the anterior frontal carina is more arcuate and reaches from 

 one gena to the other, the posterior carina is somewhat more 

 laminate, the very short triangular carina on the vertex is slightly 

 more prominent than in 0. granulum, and the punctures in front and 

 behind the second frontal laminate carina are very much finer, being 

 aciculate only; the prothorax is simple but bears in the anterior part 

 of the apex a minute tubercle, the shape is the same as that of 

 0. granulum, but the punctures are slightly smaller, and all of them 

 extremely briefly setigerous, and so are the punctures on the 

 intervals of the elytra, those of the pygidium are alike.

Black, very little if at all metallic, briefly pubescent, antennae 

 fuscous black ; clypeus semi-circular, emarginate in the centre, the 

 margin slightly reflexed, head simple, clypeal and also the anterior 

 frontal parts transversely carinulate plicate, the plication somewhat 

 interrupted and sub-scabrose in the frontal part, and replaced on the 

 vertex by confluent, sub-rugulose punctures ; prothorax simple, 

 covered with round, uniform punctures very closely set and separated
