A common insect of the “ tierra templada ” of Mexico and Central America, occurring 
chiefly at elevations of from 3000 to 5000 feet. Thisis the largest species of the genus 
in Central America, and may be readily known by its black body and partly rufous 
head. In the male, joints 4-6 of the antenne are thickened and deformed, greatly 
produced on the upper side ; the middle tibie are distorted and compressed, dilated at 
the apex, and excavate above and beneath in their outer half; and the sixth ventral 
segment is feebly emarginate. In the female the antenne are thickened towards the 
tip. The spurs of the hind tibie are stout and obtuse, the outer one much wider than 
the other. Varies in length from 14-45 millim. (exclusive of abdomen).
