with which they would undoubtedly be confused but for the shape of 

 the genital armature of the male, which, although of nearly the same 

 shape, is, however, different. 



Length 13|— 20 mm. ; width 7J-10 mm. 



Hob. Transvaal (Klerksdorp, Pretoria, Waterberg) ; Southern 

 Rhodesia (neighbourhood of Zambesi River) ; Damaraland. 



SCHIZONYCHA CITIMA, 



Plate XLIIL, fig. 61. 



Sub-cylindrical, pale testaceous, head and prothorax light-chest- 

 nut ; club of antennae long, flavescent ; head and prothorax similar 

 in shape to those of S. valida, the sculpture is also of the same kind, 

 but much less deep, and with the intervals less scabrose or not at all 

 raised in the posterior part ; the punctures on the elytra and on the 

 pygidium are alike, but the elytra are not coriaceous ; the upper 

 tooth of the claws is a little more slender, but longer than the lower ; 

 the branches of the forceps of the genital armature are more con- 

 stricted laterally about the median part, more divaricating thence, 

 not as obliquely truncate at apex, and have no small triangular 

 projection in the inner part above the inner angle. 



Length 15-17 mm. ; width 7— 7-J- mm. 



Hob. Southern Ehodesia (Manica, Salisbury). 



SCHIZONYCHA TUMIDA, Cast., 



Plate XLL, fig. 58. 

 Hist. Natur. d. Col., ii., p. 133. 



Chestnut-brown, with the elytra a little redder and the head slightly 

 darker than the prothorax, club of antennae flavescent, a very small 

 white hair in each puncture ; clypeus semicircular, clypeal carina 

 moderately arcuate and without any distinct trace of a clypeal 

 suture, the basal carina is sharp, slightly angular in the centre, the 

 surface of the whole head, with the exception of the space beyond the 

 basal carina, is covered with closely set, contiguous, sub-scabrose 

 punctures ; prothorax ampliated and rounded laterally in the median 

 part, the outer margin is finely serrate and normally setulose, -the 

 whole surface is covered with somewhat small, round punctures equi- 

 distant and separated by an interval equal in width to their diameter 

 except along the anterior margin, where they are set very closely ; 

 scutellum with two lateral rows of deep punctures ; elytra cylindrical, 

 covered with round punctures equal in size to those of the prothorax, 

 and set at the same distance from each other ; pygidium with
