broadly rounded, the anterior part does not bear any erect bristles, 

 being merely less densely villose than the frontal part and vertex ; 

 the villosity of the prothorax and scutellum are alike in both species, 

 but the white hairs on the elytra are shorter and much more 

 squamose in C. dcbilis than in C. fuscivcntris ; this difference in the 

 shape of these white hairs is plainly noticeable on the propygidium, 

 pygidium, and under side of G. debilis, which are very distinctly 

 squamose white. 



Length 11 mm. ; width 6 mm. 



Hab. Transvaal (Zoutpansberg).

SCHIZONYCHA FEIEANA, n. Sp. 



Eusty-red or reddish chestnut, shiny, palps and antennae 

 flavescent ; head slightly darker except the neck than the pro- 

 thorax or elytra, the reflexed anterior margin of the clypeus is very 

 conspicuously emarginate in the centre in the $ , but not even 

 sinuate in the $ , the frontal carina is merely slightly arcuate in 

 the $ , barely distinct at some distance from the canthus of the 

 eye, and the basal carina is very sharp, whereas in the ? it is very 

 broadly triangular with the median part undoubtedly sharp, the 

 basal carina is much less sharp, and the surface of both the clypeus 

 and the head with the exception of the neck is rugosely asperate 

 foveolate ; prothorax one-fourth wider than the median length, 

 strongly attenuated obliquely laterally from the anterior angle to 

 the median part, thence ampliate and moderately rounded as far as 

 the base, covered with punctures separated by an interval about 

 equal to their diameter, slightly rugose in the $ , plainly variolose 

 in the 2 which has also an abbreviated median smooth elongated 

 area, absent in the $ , the smooth supra-basal lateral fold is also 

 more conspicuous in the $ ; elytra of the usual shape and sculpture, 

 the punctures hairless in both sexes, slightly rougher on the 2 ', 

 penultimate abdominal segment wider than the antepenultimate ; 

 pectus very sparingly hairy ; anterior tibiae tri-dentate outwardly, 

 upper claw more slender than the lower and of about equal size. 

 The clasps of the $ resemble those of S. vicaria, but the two 

 branches are more slender — the longer one distinctly sinuate out- 

 wardly, and the apical part is more spatuliform. 



Length 14-14^ mm. ; width 6-7 mm. 



Hab. Zambesi Eiver (Feira). 



The male of this species is easily recognised by the more than 

 usual narrowed anterior half of the prothorax.
