 black hair, and often a small patch of white hair each side at tip; wings thinly 

 clothed with black and gray hair, and some scattered white ones near base, two 

 prt)minent patches of erect black hair just beyond the middle of the wing; the 

 fringe dark gray, except near the tip on each side, where it is whitish, giving the 

 appearance of a white margin to a black wing; it is very long, on the posterior 

 margin nearly as long as the breadth of the wing; legs dark, with gray hair. 

 Antennse slender, black, with whorls of gray hair, about as long as the width of 

 the wing ; wings narrow, acute at tip. The inferior pair of male appendages are 

 long and slender ; at first they are parallel, then they diverge and curve upward ; 

 they are clothed with fine black hair ; the superior pair are very far apart at base, 

 about two-thirds as long as the inferior pair, gradually tapering and but little 

 curved toward each other. Length of wing 1.8-2 mm.
