400 Harrises Description of 



terior edge, and a deep sinus of the margin on each side, 

 within which the labial palpi are inserted and nearly con- 

 cealed. Maxillae horny, the inner lobe very hairy, and armed 

 at the tip with a small tooth ; the terminal lobe not articu- 

 lated at right angles with the base, but curved inwards beyond 

 the middle, where it is armed with a sharp tooth, and tapering 

 at the end, which is furnished externally with a long and thick 

 pencil of tawny hairs.* Thorax orbicular or rounded behind ; 

 in the females indented before the middle, and elevated into 

 a tubercle on the anterior edge. Epimera large and con- 

 spicuous above, between the outer angles of the thorax and 

 the shoulders of the elytra. Body robust ; back convex ; 

 elytra gibbous behind. Abdomen not indented or furrowed 

 beneath, in either sex ; the extremity densely fringed with 

 hairs, and immaculate. Forelegs of the males elongated ; 

 anterior tibiae unarmed, but covered with minute asperities on 

 the inner side, and furnished with a downy pad beneath the 

 base ; three-toothed externally in the females. Claw-joints 

 and claws of the forefeet very strong and robust in the males. 

 Four posterior tibiae fringed internally with hairs in both 

 sexes, and armed with a spine on the middle of the outer 

 edcre in the females. 



The subgenera, named Dicronorhina and Mecynorhina by 

 Mr. Hope, are found in Western Africa. They differ from 

 the foregoing in the form of the thorax, which is trapezoidal, 

 or broad behind and narrowed before ; moreover, the body is 

 not so robust and convex ; the shoulders of the elytra are not 

 so prominent ; and the epimera are not so large and conspic- 

 uous as in the subgenus Hegemon. In the males, the clypeus 

 is horned, the forelegs are the longest, and always differ from 

 those of the other sex, the claw-joints and claws of the fore- 

 feet are very strong and robust, and the middle of the abdo- 

 men is concave or furrowed beneath.

* The trophi are correctly figured in Mr. Hope's "Manual," plate TIT., excepting 

 the maxillfe, in which the articulation of the terminal lobe with the base is not 

 shown.
