angles than long in middle (1.4:1), hollowed out, median carina 
present on basal third; frons scarcely longer than wide. Tegmina with 
Sc+R fork about middle, a series of 11 apical cells distad of stigma, 
six subapical cells, the third smallest, triangular. 
Vertex very pale, a fuscous mark basad of each areolet, a larger dark 
spot at each basal angle, areolets pallid, a pair of spots in depression 
of each; frons fuscous, a broad pale band transversely just basad of 
middle, extending on to genae to eyes, lateral margins regularly barred 
with fuscous and pale spots alternately; clypeus fuscous with a trans- 
verse pallid band across base, extending on to genae, and a smaller 
transverse band near apex; antennae with second segment pale fuscous, 
pallid at apex, eyes brown, mottled fuscous; pronotum with disk, 
carinae, and margins of areolets pale, depressions of areolets, and a
