 which includes marginal (except base), third submarginal, and apex 

 of third discoidal cells, second submarginal cell somewhat oblong, 

 much smaller than third especially in height, receiving the recurreut

 coarsely punctured anteriorly, its fore margin slightly incurved ; 

 eyes reaching base of mandibles, converging above, separated at the

 joints; space between hind ocelli greater than that between them

 second ; front feebly impressed ; pronotum angulate beneath, not 

 tumid ; middle segment rounded, convex, its upper surface parted 

 by a shallow furrow, smooth and somewhat shining at extreme apex ; 

 legs strongly spinose, the hind tibiae with the serration unusually
