 resembles C. linearis, but is more robust, the head and 

 second segment of the body being deeper and shorter 

 than in that species. The antennae are slender : the 

 superior in the male are nearly twice as long as the 

 inferior, the peduncle of which scarcely reaches to the 

 extremity of the second joint of the superior; the flagel- 

 lum of the latter being composed of very few articuli. 

 In the female the peduncle of the lower antennae appa- 

 rently extends as far as the extremity of the peduncle of 

 the superior, which is, however, mutilated in our unique
