 Cephalon about one-third wider than 

 long. Frontal margin truncated, with 

 a prominent median lobe and the sides 

 oblique. First segment of the peraeon 

 longer than the two following segments 

 combined. Pleon nearl}^ equal to the 

 peraeon in length. The coalesced seg-

 ment convex ; the posterior third is 

 almost free from granules, and the 

 extremity has an inferior median semi-
