small granules in the lateral, anterior part ; elytra deeply and 

 closely punctato-striate, intervals a little convex, especially in the 

 posterior part, and filled with deep, contiguous punctures ; pygidium 

 deeply and closely pitted ; metasternum nearly smooth for the 

 greater part of the length, and having a basal fossa and a faint 

 longitudinal line in the male, and a broader basal impression and a 

 distinct longitudinal groove in the female ; apical spurs of anterior 

 tibiae truncate at tip and produced at right angles into a long, sharp 

 spine. 



This species is distinguished from C. klugi by the shape of the 

 prothorax, which is distinctly bi-impressed in the median declivous 

 part, and not in the supra-lateral one, the transverse carina extends 

 ulso more towards the sides, and is more abruptly curved there, it 

 is also more broadly sinuate in the middle, the punctuation both on 

 the prothorax and on the elytra is l)roader and deeper, and the striae 

 are very distinctly and deeply punctate ; from G. sohrina in which 

 the striae are as deeply punctured as in C. optata, and which has 

 also two median impressions on the sloping part of the prothorax, 

 it differs by the carina extending more towards the sides thus 

 giving the sloping part a more quadrate shape, the anterior 

 bi-impressed part is also broader and more quadrate, and the 

 punctuation on the prothorax and the elytra is a little deeper ; 

 the outer angle of the apical spur is not spinose. 



Length 12-14 mm. ; width 8i-10 mm.

Black, head and prothorax opaque, elytra shining ; head trans- 

 versely and roughly plicate, genae diagonally attenuate and in a line 

 with the clypeus which is slightly sinuate next to the apical teeth 

 which are comparatively short, triangular, reflexed, not carinate 

 longitudinally, and separated by a sharp, triangular incision, in a 

 line with the anterior part of the eyes there is a transverse impressed 

 line broadly interrupted at middle ; prothorax very slightly sloping 

 in front, and having in the centre of the anterior part at a short dis- 

 tance from the middle two transverse carinate tubercles and a very 

 slight impression on each side of them, the outer sides are very 

 slightly attenuate from the outer angle to a short distance from the 

 middle, and straight from there to the base, the whole surface is
