head is somewhat transverse, falling away abruptly in front; 
seen from in front it is higher than broad at top, gradually 
narrowing below to the mandibles. Mouth directed downward, 
mandible narrow, almost lineal, scarcely emarginate at the end. 
Eye very large, very prominent, almost semiglobose, and bare.
