Antennae short. 



Collum convex from side to side, tlie anterior border evenly 

 rounded from the apex of one keel to that of the other, tlie 

 keel triangular, depressed, its posterior border oblique and not 

 continuing the curve of the hinder border of the tergite ; a 

 transverse groove sometimes running along the anterior border, 

 closely covered with rounded tubercles, those along the two 

 borders larger than the others. Tiie rest of the segments 

 granular or tubercular like the first, all of them marked with 

 three distinct rows of larger tubercles ; the keels slightly de- 

 pressed, rising a little above the middle of the side, not large, 

 squared, the anterior border smooth, with a distinct basal 

 shoulder, the posterior border smooth, the lateral border 

 furnished with from 4 to 6 smooth rounded tubercles (that is 

 including the anterior and posterior angle). Pores close to 

 the lateral margin, separated from it by a space about equal 

 to their own diameter. 



Anal tergite evenly rounded, at most lobulate. Lateral 

 surface of the segments closely granular and rugose. 



Sterna not spined. 



jj . A little narrower and flatter than the female, the keels 

 being a trifle larger. The copulatory feet terminating distaliy 

 in two processes, the distal simple, long, slender, and lightly 

 curved, the proximal itself dividing into two — an upper 

 strongly curved and dilated at its distal end, an under simple 

 and pointed.
