Diagnosis

The head is produced and spatulate, ventrally concave and dorsally convex. The ante-and frontoclypeus are flat and bordered laterally with deep depressions. The antennae, which are very long, are inserted close to the anterior apical border of the head. The sides of the head on each side are emarginate above the antennae and below the ocelli, and the ocelli are close to the sides of the crown and nearer to the apex than to the eyes. The coronal suture is long and the greater part of the crown consists of the vertex. The pronotum is collar-like and parallel-sided and in the tegmen M1+2 appears to be more than a mere crossvein. The hind tibiae have a row of evenly spaced short strong spines set on enlarged bases, a row of long strong spines, another of short spines and one of hair-like spines (Evans 1942).
