LE CONTE.—LONGICORN COLEOPTERA 
This genus is very close to the preceding, and only differs in the structure of the 
antennae. These organs in the male are rather thick, with the sixth and following 
joints compressed. Carinated on the edge, with a denuded granulated elliptical 
impression of each side; the eleventh joint is constricted in the middle and furnished 
with two pairs of impressions. In the female the antennae are less compressed, the 
side not carinated, the impressions are smaller than in the male, those on the external 
surface being sometimes scarcely visible. The body is arched, and narrowed at each 
end.
