broad ; prothorax abruptly truncate in front, the truncate part decli- 

 vous and edged by a transverse carina slightly emarginate on each 

 side and ending in a lateral angle which does not project beyond the 

 slope, it is in a line with the lateral impression which is elongate 

 and not very deep, the anterior angles are obtuse, and the anterior 

 margin distinctly emarginate in the centre, the whole surface is 

 covered with very closely set granules ; elytra as broad as the 

 prothorax at base, convex, somewhat gibbose at middle, the eighth 

 stria is very sharply carinate, and extends from the base to the 

 median part, the intervals are smooth, but a little coriaceous at 

 base, and the striae are very faintly punctulate. 



In the very large development, of which I have seen several 

 examples collected by Mr. F. G. Selous, in Manica, the colour is 

 quite black, the cephalic horn is 5 mm. long and 3 mm. broad, and 

 is rounded at tip, the lateral angle of the prothoracic carina is 

 strongly developed ; in the small development from the same 

 locality the horn is reduced to a sharp, conical tubercle, hardly 

 2 mm. high, quite vertical, and situated nearer to the base than to 

 the apical part ; the prothoracic carina is hardly angular laterally 

 and nearly straight. 



Female : The shape of the head is similar to that of the male, 

 but instead of a slanting horn it has a short carina bearing a small 

 sharp median tooth about IJ mm. long, and the edges of the carina, 

 which is about 4 mm. broad, are sharp ; the prothorax is also 

 declivous at apex, and the declivity is bounded by a carina, but the 

 carina is placed much more forward than in the male, occupies only 

 the centre of the disk, and is in a line with the lateral impression 

 which is transverse, instead of being longitudinal as in the male ; 

 the granular surface is identical, and the sculpture of the elytra 

 exactly similar to that of the male. 



Length 32-39 mm. ; width 19-22 mm.
