In this genus the wings are small and narrow, and not notched at the apex; 
occasionally they appear to be rudimentary. The forehead is perpendicular and the 
clypeus more or less inflexed. The species may be known by their peculiar rough 
facies and strongly raised venation, and their general shape, which is, as a rule, very 
convex and almost subglobular. The number of spines on the posterior tibie appears 
to be variable.
