crown and adjacent eye angle, disk of crown with a transverse concavity be- 
tween ocelli, continuous with shallow depression on each side laterad of 
ocellus, surface with a few oblique rugosites mesad of each ocellus, without 
setae, lateral clypeal sutures extending onto crown and attaining ocelli; an- 
tennal ledges slightly protuberant in dorsal aspect, in lateral aspect with an- 
terior margins each obliquely convex; face with sparse pubescence below, 
clypeus flattened medially and with vermiculate rugosities, swollen laterally 
and with muscle impressions distinct, transclypeal suture obsolete, clypellus 
laterally compressed, contour of its lower portion at right angle to profile of 
face. 
Thorax with pronotal width much greater than transocular width of head, 
lateral margins strongly convergent anteriorly, dorsopleural carinae almost 
complete (almost reaching eye), posterior margin convex, with a rectilinear 
transverse sulcus subtending anterior margin, disk strongly elevated, convex 
and weakly transversely rugulose at middle, without pubescence; scutellum 
not rugose on posterior half. Forewing with membrane including only inner 
apical cell, veins distinct, not elevated, with more than four apical cells, the 
base of fourth not more proximal than base of third, inner anteapical cell
