covered with very closely set granules replaced in the centre of the 

 basal part by sub-foveolate punctures, and there is a faint, median, 

 longitudinal impressed line reaching from between the two anterior 

 tuljercles to the base ; elytra deeply striate, the striae punctate and 

 encroaching on the intervals which are convex from a very short 

 distance from the base, and seemingly impunctate, lateral sinuation 

 above the metasternal epimera strong ; pygidium closely and finely 

 pitted ; median part of metasternum faintly aciculate and punctulate 

 in the median part, deeply impressed at base and with a longitudinal 

 sulcus stopping beyond the middle ; apical spur of anterior tibiae a 

 little curved outwardly, bent at right angles at tip, produced in a 

 sharp inner spine, and with the outer angle of the bent part acute. 

 In the small development the thoracic tubercles disappear com- 

 pletely. 



Easily distinguished from C. aaspicata by the absence of arcuate 

 cephalic carina, the shorter clypeal teeth, the more distinctly 

 granulate prothorax w^hich is scarcely retuse in the anterior part, 

 faintly impressed, and not carinate on each side of the two 

 tubercles, and also by the convex and smooth intervals of elytra. 



Length 8-12 mm. ; width ^h-lh mm.

" Ob-ovate, strongly convex, black, sub-opaque ; head and prothorax 

 finely and closely roughly punctate, the former is slightly emar- 

 ginate in front, and broadly and obtusely dentate on each side ; 

 elytra finely punctato-striate, with the intervals plane and finely 

 but moderately closely punctulate. Equal in size to the small 

 examples of C. Klurji, but it is distinguished by the head, the apex of 

 v\hich is only slightly emarginate and very briefly and obtusely 

 dentate, by the shape of the prothorax which is equally convex in 

 front and l)ehind, and by the intervals of the elytra, which are 

 more finely punctulate ; antennge piceous black." 



The co-type of Boheman, wdiich is the only example of this species 

 I have seen, is equal in size to C. niticlipcrmis, but the prothorax is 

 quite convex. 



Length 12 mm. ; width 8 mm.
