striped longitudinally with dark brown; legs brownish black; 
wings very long and narrow, strongly suffused with brown; 
cell M, present.

Male.——Rostrum brown; palpi dark brown. Antenne dark 
brownish black, short. Head dark brownish gray; vertex behind 
antennal bases light gray pruinose; immediately caudad of the

longer than R; r—-m on R,+, about two and one-half times its 
length beyond the fork; petiole of cell M, a little shorter than 
cell; basal deflection of Cu, just beyond midlength of cell 1st 
M,; in the right wing of the type, R, just before its tip bends 
down to R, in a punctiform contact; in the left wing of the same 
specimen there is a supernumerary cross vein in cell R, just 
beyond r. 
Abdomen with tergites 1 to 4 bright orange; 5 to 7 orange
