Onthophagus glaber, Frihr., 

 Insect. Caffr., ii., p. 285. 



Fuscous bronze and occasioncally with a red, ferruginous tinge, 

 shining ; antennae yellow ; head very closely and finely punctured 

 equally on the vertex and on the clypeus which is semicirculai-, a 

 little blunt at tip and slightly emarginate there, that of the female 

 beingahttle more distinctly emarginate than in the male, there is an 

 arcuate frontal carina extehding to a short distance from each eye and 

 continued sub-diagonally above the eye close to the base where there 

 is a sub-basal transverse carina very Httle raised, and interrupted in 

 the middle, both these carinae are very little raised, but the frontal 

 one is nevertheless distinct ; prothorax moderately convex, a little 

 ampliate laterally, neither impressed nor retuse in front, marginate 

 all round, rounded at base and covered with closely set, very fine 

 punctures which are hardly setigerous; elytra ovate, hardly ampliate, 

 very narrowly striate, strias geminate and finely punctate, intervals 

 plane and filled with several series of very fine round punctures 

 which are also hardly setigerous, second interval very little wider 

 than the third, humeral callus distinct ; pygidium closely aciculate ; 

 metasternum entirely smooth in the middle, and having a slightly 

 impressed median longitudinal line ; inner part of the anterior tibiae 

 non-spinose at apex ; apical spurs moderately slender, curving a 

 little outwardly in the male, and nearly straight in the female. 



Length 8 mm. ; width 4-| mm. 



Closely allied to 0. moestus in general appearance, but easily dis- 

 tinguished by the presence of a frontal carina, and the more finely 

 punctured prothorax and elytra, the intervals of the latter are 

 aciculate ; it very much resembles the female of 0. interstitiaUs, 

 to which Harold erroneously assimilates it, in general facies, but 

 the shape of the cephalic caringe is different, and the punctuation 

 ■of the prothorax is finer and more closely set. 



Hab. Transvaal (Eustenburg), Cape Colony (Griqualand West). 



Onthophagus discretus, n. spec. 



Black, shining, very briefly pubescent; antennae yellow; head 

 covered with deep, closely set punctures, genae rounded and not 

 projecting beyond the line of the clypeus which is semicircular, 

 and very slightly emarginate in front, there is only a very faint 

 trace of an arcuate frontal carina which is, oftener than not, quite 

 obhterated, vertex simple ; prothorax moderately ampliate and not 

 rounded laterally in the middle, moderately convex, marginate all
