part, wliereas in 0. unonuihis it diverges outwardly towards the 

 penultimate outer tooth and the apical inner part is dilated ; and in 

 the ? the clypeus is triangular and not so sharp at tip.

This species is also closely allied to the two preceding ones, and is 

 a soiliewhat intermediate form. The prothorax is as closely scabroso- 

 punctate as in 0. dcceptor ; the head and clypeus are similar; the 

 anterior tibiae of the male, liowever, are distinctly ampliated internally 

 from opposite the second basal outer tooth, and the upper carina 

 runs there in the median part, the four outer teeth are equi-distant, 

 the curve of the intermediate tibiae is intermediate between that of 

 0. dcceptor and 0. curvipcs, and the posterior tibias and femora are 

 similar to those of the last-named species, with which it is intimately 

 connected. 



Length lOi-25 mm. ; width 10-11 mm. 



Hah. Southern Ehodesia (Limpopo Eiver) ; occurs also in Abys- 

 sinia and Victoria Nyanza. 



Onitis deceptoe, n. spec. 



Very similar to 0. curvipcs, Lansb., in both sexes ; it differs mainly 

 in the sculpture of the prothorax, the whole punctures of which are 

 distinctly more scabrose and a little more closely set right down to 

 the base, and there is no trace of a longitudinal median sulcus, the 

 elytra are more opaque and the intervals not coriaceous, the pygidium 

 is more granulosa, the size is also generally a little smaller, and in 

 the male the tibiae are quite straight inwardly and the upper inner 

 carina runs quite parallel to the edge, wdiereas in 0. curvipcs it is a 

 little sinuate and does not run near the edge, underneath the carina 

 also runs near to the edge, is bi-serrate at about the median part, has 

 a very distinct vertical tooth tow^ards the base at about one-third of 

 the length, and the whole carina is only half the size of that of 0. 

 curvipcs, all the femora are similar, but the intermediate tibiae, 

 although having nearly the same shape, are not bent at quite so 

 sharp an angle, and the lamelliform ampliation is more regularly
