Like Superior, not rare. This is an osculant between this division from which 



it borrows the slender subquadrate antennal joints, and the first division, t" which it ap- 

 proaches by tli what obliquely attenuated elytra; the elytra are, however, do! 

 strongly margined, and possibly a nearer appr >ach is made to C. tarsalis, of the preceding 

 division. The posterior angles of the thorax are finely and strongly carinate, and the 

 carina is parallel to the lateral margin. The sides of the thorax are more ronnded in the 

 female than in the male, anil t ho thorax is 1' ?s n irrowed in front ; the anl (* the female 

 are hardly longer than the thorax, those of the male are marly half as lung as tin- !• idy.
