The varietal form with the black patch on the elytra comes from 

 the Cape Colony, and is the only example of its kind that I have 

 seen. 



Onthophagus litigiosus, n. spec. 



Fusco-aeneous, nearly black, sub-opaque, very briefly setigerous ; 

 head very closely punctulate and without trace of carinoe, gense 

 slightly diagonal externally, clypeus acuminate and not rounded 

 laterally, briefly obtuse and not emarginate at tip ; antennae fuscous ; 

 prothorax ampliate but not rounded laterally at middle, very little 

 convex, marginate all round although less distinctly along the base 

 which is slightly aculeate in the centre and covered with closely set, 

 a little elongated punctures ; elytra finely geminato-striate, the striae 

 feebly punctate, intervals plane and very vaguely aciculate, the 

 aciculate punctures being very briefly setigerous, second interval 

 not wider than the third, humeral callus distinct ; pygidium deeply 

 and closely pitted ; metasternum closely punctate all over and 

 having a very faint median longitudinal smooth line ; inner part 

 of anterior tibiae aculeate at tip but not spinose in either sex, apical 

 spurs nearly straight, moderately slender. 



Length 4 mm. ; width 2^ mm. 



Hah. Mozambique (Eikatla). 



Onthophagus discrepans, n. spec. 



Male : Black, sub-opaque, with the intervals of elytra moderately 

 shining, dark bronze underneath ; head very roughly and closely 

 punctate, genae triangular, clypeus arcuate, not emarginate at tip, 

 no trace of transverse carina ; prothorax moderately convex, 

 ampliate, but not rounded laterally at middle, marginate all round, 

 base a little acuminate at middle, it is covered with deep, confluent, 

 round punctures, is very briefly pubescent, and is slightly impressed 

 longitudinally in the middle of the posterior part ; elytra very 

 ampliate, very narrowly but deeply geminato-striate, striae seem- 

 ingly not punctured, intervals a little convex and having each two 

 series of large setigerous granules almost tuberculiform on the three 

 first ones, second interval not broader than the third ; pygidium 

 closely punctate ; metasternum very closely and deeply punctured 

 in the whole of the median part, which is slightly acuminate at a 

 short distance from the apex, and has a very broad, deep basal 

 depression with the median line distinct for half the length only ; 

 inner angle of anterior tibiae rounded, apical spur very short and 

 strongly bent outwardly.
