sides, and faintly impressed longitudinally in the centre of the 

 posterior dorsal part ; elytra ampliato-ovate, finely striate, the 

 strige finely geminate and punctulate, intervals plane, finely punctu- 

 late, and the punctures briefly setigerous, humeral callus not very 

 prominent, second interval a little broader at middle than the third ; 

 pygidium closely punctured ; metasternum covered with scattered 

 punctures, slightly grooved longitudinally in the centre and having 

 a deep, basal impression ; inner angle of anterior tibiai non-spinose, 

 apical spur thickened and turned inwards at tip in both sexes. 



Male : Clypeus semicircular, hardly sinuate laterally, frontal 

 •carina not much raised, between this carina and the base there is 

 a long, nearly vertical horn, cylindrical except at the l3ase, and 

 rounded at tip ; median part of the anterior part of the prothorax a 

 little flattened, and impunctate, the length of the cephalic horn 

 varies from f to 2h mm. In the small development there is no 

 impunctate part in the anterior part of the prothorax. 



Female : Clypeus a little more acuminate in the centre than in 

 the male, but not much, frontal carina a little more raised, at a 

 short distance from the base there is a transverse carina only a little 

 more raised than the frontal one, and nearly straight ; prothorax 

 not depressed in the anterior median part. 



Length 8J-9J mm. ; width 4|— SJ mm.

Very closely allied to 0. girajfa in general appearance, but the 

 head is much more granulose; the prothorax, instead of being covered 

 with punctures, is very closely granulose all over, the apical spur 

 of the anterior tibiae are not as broad and are nearly straight in 

 both sexes. The cephalic horn of the male is not curved, and is 

 more cylindrical. 



Length 9J-9|^ mm. ; width 4^-4f mm. 



Hah. Natal (Durban). 



Onthophagus vigens, n. spec. 

 Male : This species is so closely allied to 0. giraffa that it might 

 be easily mistaken for it. It is, however, a little smaller and not so
