carina extending from eye to eye, more transverse in the male than 

 in the female, suture of genae wholly or partly obliterated, eyes 

 showing very little on the upper side, clypeus semicircular, emar- 

 ginate at apex ; prothorax very convex, somewhat retuse in front, 

 marginate all round, lateral supra-marginal fossa not conspicuous ; 

 elytra very convex, as broad as the prothorax at base, ampliate 

 laterally in the middle, deeply striate, striae not geminate, eighth 

 interval sharply carinate above the outer margin, which it slightly 

 overhangs, no wings, epipleura moderately narrow, in some 

 species there is a supra-marginal stria obliterated in the anterior 

 part, which is apt to disappear wholly or partly, and is called 

 the pseudepipleural stria ; pygidium sub-vertical ; metasternum 

 not very broad between the coxae, divided from the mesosternum 

 by a slight suture, mesosternum narrow ; anterior tibiae quadri- 

 dentate externally, the basal tooth small, strongly dentate inwardly 

 at apex in the male, but not in the female ; intermediate and 

 posterior tibiae dilated triangularly at tip, bi-carinate longitudinally 

 on the upper side, but not deeply grooved ; tarsi of CojJris, the basal 

 joint more dilated at apex than the others, and as long as the two 

 following, but the claws are greatly developed ; body somewhat 

 spherical. The habits are also those of Copris. 



In the male the apical spur is straight and slender, but in the 

 female it is thicker and sharply curved inwardly at tip. 



This genus is restricted to South Africa. 



De Borre and Sharp have published the description of six species, 

 of which I have only been able to identify two with some certainty. 

 Unfortunately these descriptions are based on very few examples (in 

 several cases a single one), the sex of which has not been always 

 ascertained. Von Harold had previously described also one species 

 which, according to him, is found on the western coast of South 

 Africa as far as the country of the Hereros, i.e., N'Gamiland. I 

 have added two species, one of which is very distinct ; the other, 

 described from one example only, is also very distinct, but might 

 prove to be malformed. 



The shape of the genital armature is the same in all the species 

 I have seen. 



Key to the Species. 



A-. Lateral margin of prothorax not sulcate, crenulate behind. 

 B". Intervals of elytra granulose. 



Prothorax covered with very elongate punctures enclosing a 



small granule grceni.
