Wings about four times as long as broad, generally a trifle less 
than more, uncolored except for the generally distinct and rather 
small stigma. Auxiliary vein terminating at the middle or 
scarcely beyond the middle of the inner marginal cell; poststig- 
matal cross vein transverse or scarcely oblique, rather short ; trape- 
zoidal cell rather elongate. Prafurca of normal length. Petiole 
of second posterior cell generally rather short, rarely exceeding 
half the length of the discal cell, but sometimes slightly longer 
than that; fifth posterior cell somewhat, sometimes considerably, 
broader at base than at margin. Discal cell not very large, elon- 
gate, fully twice as long asbroad. Fourth longitudinal vein usually 
running slightly nearer the first than the fifth longitudinal vein, the 
sixth longitudinal vein ‘moderately approximated to the fifth; 
seventh longitudinal vein as in 7. florissanta. Legs slender, the 
tibiz considerably slenderer than the femora, the hind femora 
slightly longer than the others and nearly two thirds as long as the 
wings, the tibize and especially the fore pair distinctly longer than 
the femora, and the tarsi more than half as long again as the tibiz. 
Abdomen light colored, with a dark median longitudinal stripe, 
sometimes obscure and generally rather broad, and pretty uniformly 
distinct and equally broad dark lateral stripes—all occasionally 
obscured in preservation.
