 2 nd segment the longest, the rest subequal. 



First tergite or collum gradually narrowed laterally, its lateral border 

 generally convex; the 2 nd segment projecting below the 1 st . The trans-

 distal hairy, the rest smooth. 



The first tergite smooth, the lateral portion feebly margined in 

 front, not striate, the angle rounded and not extending so low as the 

 inferior extension of the second. The rest of the somites finely striolate
