 between considerably more than the length from eye to vertex but less than 

 twice as much ; flatly convex above, depressed in front, tumid beneath, deep- 

 est beneath the posterior end of the eye ; vertical margin straight, temples 

 rounded, eyes convex ; antennae almost reaching the mesoscutum, the seg- 

 ments of the flagellum all longer than wide, pedicel twice as long as wide, 

 antennal fossae deep ; clypeus short, nearly horizontal, medially longitudi- 

 nally elevate and sloping at the sides, extended a little in front of the ante- 

 rior margin of the head; mandibles large, bent in the middle and twisted, 

 the distal portion flattened, truncate apically and toothed, base not reaching 

 the eye ; cheeks narrow ; gula and sides of the head rather flat, the former 

 medially foreshortened, wider than long, narrowing a little and slightly pro- 

 tuberant beliind, a shallow sulcus separating the two lobes ; abdomen elon-
