*' Convex, piceous black, shining ; head large, sparingly punctulate, 

 moderately closely, irregularly aciculate transversely, and having 

 three strong corniform teeth in front, lateral teeth sharp, short, 

 apical ones larger and obtuse ; prothorax closely and roughly 

 granulate, finely and sparingly punctate in front and behind, im- 

 pressed transversely behind the apex which is clothed with long, 

 ferruginous hairs, and armed there with five horns the lateral ones of 

 which are short and acuminate, while the median one is long and 

 truncate at apex ; elytra dark chestnut-brown, moderately deeply 

 striate, with the intervals sparingly and finely punctulate.

Hah. "Interior of Caffraria, very seldom met with," according 

 to Boheman. 



I have not as yet seen any example of this species from South 

 Africa, but Boheman records it. 



Heliocopeis piRMAL, Fabr.,

Burm., Gen. Insect., i., pi. iv., figs. 1, 2. 



Black or piceous black, elytra shining ; head transversely plicate 

 on the clypeus as far as the cephalic horn or transverse carina, and 

 more or less transversely scrobiculate behind ; prothorax scrobicu- 

 late in the anterior and median parts, the scrobiculation giving way 

 to a rough granulation on the sides and along the base ; elytra very 

 narrowly punctulato- striate, striae not geminate, intervals slightly 

 raised ; pygidium vaguely and somewhat closely punctate ; meta- 

 sternum with a deep, broad, basal impression. 



Male : Clypeus sub-semicircular, but a little angular laterally at 

 middle, junction of gense and clypeus distinctly triangular, on the 

 head an ante-median, short, narrow, laminate horn, emarginate at 

 tip ; prothorax vertical in the anterior part and not excavated there 

 but having the lateral angles long and sharply acuminate, two 

 supra-lateral triangular teeth and a median projecting lobe, ending in 

 two long corniform teeth curving dow^nward, and projecting beyond 

 the base of the head ; the anterior part is clothed with dense, long, 

 fulvous hairs, and the median part of the disk is slightly, yet broadly 

 depressed.
