towards the anterior part, clypeal carina moderately arcuate and 

 having behind an impressed line set closely against the median part, 

 the surface of the whole head, including the basal part, is covered 

 with very closely set, rugose, cicatricose punctures ; prothorax 

 ampliated and rounded laterally from the median to the basal part, 

 strongly serrate and moderately villose, the surface is covered with 

 round, deep punctures separated on the discoidal part by smooth, 

 irregular patches not quite as much raised as the supra-basal, trans- 

 verse fold ; scutellum impunctate ; elytra sub-coriaceous in the 

 anterior, and sometimes in the posterior part, covered with deep 

 punctures separated from each other by a space equal to their 

 diameter ; pygidium moderately closely punctate ; abdominal seg- 

 ments deeply and closely punctate except in the middle, each 

 puncture is setiferous, penultimate segment wider than the one pre- 

 ceding ; tarsi long, piceous-red ; upper tooth of the claws much 

 longer than the lower, and of equal thickness. The female is like 

 the male, not more convex, nor ampliate. It is almost impossible 

 to notice the difference in shape and sculpture between this species 

 and S. saga except by comparison with the latter ; the punctures on 

 the prothorax are, however, a little less deep, and the intervals are 

 not raised in the posterior part, the shape of the genital armature of 

 S. durbana differs much from that of S. saga, and hardly differs from 

 that of S. capensis, which is, however, quite a different species.

SCHIZONYCHA PEKPLEXABILIS, n. spec. 



Piceous, with the club of antennae flavescent, shape of S. durbana 

 and S. saga ; the clypeus, however, is more distinctly sinuated, and 

 the hair in the punctures are more visible on the upper side ; the 

 punctures on the prothorax are as broadly foveate as in S. saga, and 

 the intervals are similar. The shape of the genital armature is very 

 different from that of S. durbana and S. saga; it resembles that 

 of S. constrata, but the branches of the forceps are more diverging, 

 and the lateral projecting angle is quite apical, and smaller. Female 

 unknown.
