half of tlie suture, becoming united with the median patches. 

 The sutural stripe may become dilated along the posterior 

 margin and the concurrent enlargement of the median 

 patches ultimately reduces the black parts to very narrow 

 limits. 



The sexual differences are very marked. The male is 

 much more hairy than the female and the latter has the 

 elytra much more strongly punctured and very abruptly 

 angulated behind the middle of the outer margin.

This also is closely related to C. conspicua, Sharp, and, 

 like it, smooth and shining, but the abdomen, with the 

 pygidium, is black and the pattern a little different. There 

 is a black spot at each lateral margin of the pronotum and 

 the two median black lines extend from the front to the 

 hind margin, where, as well as at the middle, each gives off 

 an external branch. There is no posterior red sutural stripe 

 upon the elytra. In the female the elytra are very sharply 

 toothed behind the middle of the outer edge, much more so 

 than in C. conspicua or C. gregaria.
