 slightly bifid at tip, lateral lobes sloping a little inwardly and very 

 sharp at tip ; ligula broad, narrow and truncate in the middle, and 

 sloping slightly on each side of the apex ; paraglossas very narrow, 

 disunited from the ligula near the tip and a little longer than the 

 apical part; last joint of palpi subcylindrical, truncate at tip; labrum 

 a little emarginate ; mandibles plane, incurved at tip and long, 

 carinate outwardly on the upper part ; head short ; eyes moderately 

 large ; antennae short, terminal joints short, equal, subquadrate ; 

 prothorax transverse ; elytra broad, depressed, parallel, a little 

 sinuate behind ; legs short, intermediate, and posterior tibiae grooved 

 inwardly, the three basal joints of the anterior tibiae dilated in the
