defined ; the anterior part of the prothorax is less decHvous, and 

 there is at the top of the decUvity, which is very short, a slightly 

 sinuate rounded ridge about 6 mm. long ; the posterior part has 

 a distinct median longitudinal groove, but the whole surface is 

 granulose without any trace of smooth areolets or patches ; elytra as 

 in the male. 



The male resembles C. ulysses, but is at once distinguished, hy 

 the sub-lateral furrow below the anterior transverse carina of the 

 prothorax which, although emarginate in the centre, is not toothed 

 on each side of the emargination ; the smooth patch on the posterior 

 part of the prothorax also adjoins the carina on each side, whereas 

 in C. ulysses that patch does not adjoin the carina, and is much 

 more diagonal ; the female differs from that of G. tri-cornutus , 

 in the absence of smooth patches on the posterior part of the 

 prothorax, and also from that of C. ulysses in having the clypeus 

 emarginate in the centre as in the male.

Black, shining ; elytra sometimes dark brown. 



Male : Cljrpeus not quite rounded in front and not emarginate, 

 genae projecting a little beyond the lateral part of the clypeus, 

 the head is covered with elongate fovese separated by short, raised 

 folds, it bears in the middle a short, conical tooth about 2 mm. 

 high ; the prothorax is very declivous in the anterior part, the 

 declivity is bounded by a small carina emarginate in the centre, 

 bi-sinuate on each side, and ending at a short distance from the 

 lateral impression, this carina does not overhang the anterior 

 declivity, and is produced into a more or less sharp tubercle, one on 

 each side of the median emargination and another a little further 

 towards the sides, the anterior part is not excavated, and the 

 posterior part has a distinct impressed line from near the two 

 median tubercles to a short distance from the base, it is finely 

 granulose all over, except for a diagonal smooth space on each side 

 of the median part of the disk ; elytra narrowly striate wdth the 

 intervals finely and closely punctulate, eighth stria carinate from the 

 base to a little past the median part.
