Onthophagus obtusicornis, Fahr., 



Plate XXXV., fig. 25. 



Insect. Caffrar., ii., p. 288. 



Black, opaque on the upper part, except the strias on the elytra 

 which are distinctly shining, l^riefly pubescent on the upper side ; 

 head as in 0. i)ilosus, but the clypeus is not so deeply incised, 

 and the edges are not quite so sharp, the frontal carina is also 

 wanting, the cephalic horn is not much longer than the head in 

 the male, and is vertical, while in the female the carina on the 

 vertex is a little more discernible than in 0. pilosus ; the shape and 

 sculpture of the prothorax are identical, but the elytra have the 

 geminate striae shining and only slightly raised, and the intervals 

 have each two series of small granules not set very close together ; 

 the pygidium is granulose. The pubescence is very much shorter 

 than in 0. ijUosus, the size is also a little larger, and it can be 

 readily distinguished from 0. 'pilosus by the non-rugose intervals of 

 the elytra. 



Length 6^-8 J- mm. ; width 4-5 mm. 



Hah. Cape Colony (Griqualand West), Natal (Estcourt, Durban), 

 Southern Ehodesia (Salisbury), Mozambique (Eikatla). 



Onthophagus axillaris, Bohem., 

 Ofv. Vet. Ak. Forh., 1860, p. 114. 



This species is so closely allied to 0. ohtusicornis and 0. pilosus, 

 especially the former, that it might prove to be only a slight varietal 

 form of it. In the male the cephalic horn is either short, blunt, and 

 truncate at tip, or as long as in 0. ohtusicornis, and in the female 

 the clypeus is incised as in 0. pilosus, and the angles are therefore 

 sliarper and longer than in 0. ohtusicornis ; the elytra are sculptured 

 alike, but they have on the shoulder a small testaceous patch. 



Length 1-1^ mm. ; width 4J mm. 



Hah. Damaraland (Swakop Eiver, teste Boheman), Ovampo- 

 land (Omrramba). 



I have seen a male example in which the testaceous humeral 

 patch was entirely absent. 



Onthophagus perniciosus, n. spec. 



Bronze, a little darker on the elytra, opaque, densely pubescent ; 

 elytra with two humeral and three apical testaceous maculae ; 

 shape and sculpture of the three preceding species, but the clypeus 

 is more bluntly emarginate at tip, and the gen^ are rounded ; the
