Qead broad behind, posterior border deeply excised, vertex broadly and 

 Strongly impressed transversely; front above eyes subgibbous; cheeks swollen

 half as long as head at middle, their blades 

 of subequal thickness, slightly curved, with 

 three teeth apically, the inner of which is 

 as long as the other two and situated dor-
