OXTHOl'HAGUS OliTUSICOKNIS, FrdlV., 



Plate XXXV., lig. 25. 

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



Black, opaque ou the upper ])art, except the striio on the elytra 

 which are distinctly shiniiii^, l)rierty puhescent on the upper side; 

 head as -in 0. ihIosuk, l)ut the clypeus is not so deeply incised, 

 and the edges are not (piitc; so sharp, the fro)ital carina is also 

 wanting, the cephalic horii 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 stritB shining and only slightly raised, and the intervals 

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

 the pygidiura is granulose. The pubescence is very much shorter 

 than in O. pilosus, the size is also a little larger, and it can be 

 readily distinguished from O. p'do^us by the non-i-ugose intervals of 

 the elytra. 



Length 6i-8^ mm. ; width -i-5 mm. 



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

 Southern Rhodesia (Salisbury), Mozambique (Rikatla). 



Onthophagus axillaris, Bohem., 

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



This species is so closely alhed to O. ohtusicornis and 0. 'pilosus, 

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

 form of it. In the male the cephahc 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 iii 0. yilosus, and the angles are therefore 

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

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



Length 1-lh mm. ; width I^ mm. 



Hah. Damaraland (Swakop River, teste Boheman), Ovanipo- 

 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 macuke ; 



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



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