humeral callus indistinct; pygidium punctulate, metasternum 

 sparsely punctate, slightly carinate before the apical part; inner 

 part of anterior tibiae non-spinose ; apical spur long, moderately 

 slender, and nearly straight. 



Length 3f mm. ; width 21 mm. 



This interesting species has the appearance of a Coptorliina of 

 the G. nana group, and but for the length of the basal joint of the 

 posterior tarsi and the shape of the metasternum it might be mis- 

 taken for a species of this genus. 



Hah. Natal (Estcourt). 



Onthophagus vicabius, n. spec. 

 Black, moderately shining, very briefly pubescent ; head very 

 roughly punctured on the clypeus, vertex closely punctulate, genae 

 rounded but bulging at middle, clypeus slightly sinuate laterally, 

 deeply and broadly emarginate in the centre, and with the angles of 

 the emargination slightly recurved, frontal carina very distinct in 

 both sexes, arcuate and continued laterally as far as the eye, vertex 

 with a sub-basal transverse carina, not much raised, obliterated in 

 the centre, and also reaching the eyes; antennae flavescent ; pro- 

 thorax ampliate laterally, moderately convex, rounded at base and 

 distinctly marginate all round, it is covered with deep, closely set 

 punctures, and has a deep, narrow sulcus in the posterior part of the 

 disk from the median part to the base ; elytra very little amphate 

 laterally, narrowly geminato-striate, striae punctured, intervals raised, 

 sub-tectiform laterally, and having each two series of more or less 

 evanescent punctures, second interval not much wider than the 

 third, humeral callus not very distinct; pygidium deeply and 

 moderately closely pitted; metasternum punctulate and having a 

 narrow, smooth median space and an impressed longitudinal line in 

 the centre only ; inner part of anterior tibi® very briefly spinose at 

 tip in the male, apical spur long, moderately slender, and nearly 

 straight in both sexes. 



This species might at first sight be taken for the female of 0. 

 carbonarius or of 0. inters titialis. It is, however, distinguished 

 from these two species by the raised intervals of the elytra, and 

 the impressed line on the posterior part of the disk of the prothorax ; 

 the clypeus is much more deeply emarginate than in 0. carbonarius, 

 and the basal carina is different from that of 0. interstitialis ? . 

 The two sexes are alike. 



Length 8^-10 mm. ; 5-5i mm.
