Imago (55:1). Mead small, di-nscly clothed with scales and long hairs, arching 

 forward or curving dow-nwaril. Front nearly tlat, very little swollen, but beneath a 

 little tumid, barely surpassing the front of the eyes; above hollowed in a broadi 

 sliallow chaiuiel ilown the front; as broad as the eyes on a front view and varying in 

 height from somewhat less to scarcely more than half as high as broad ; upper border 

 forming a distinct ridge in the middle, its angles considerably hollowed in front of 

 the antennae ; lower border strongly and rather squarely arched. Vertex almost per- 

 fectly flat, with a slightly raised ridge at the outer hinder portion of each antenna, 

 and separated from the occiput by a very conspicuous, straight, transverse channel, 

 deepest in the middle. Eyes rather large and full, rather densely pilose with moderate 

 hairs, .\ntennae inserted with their hinder edge in the middle of the summit, separated 

 by a space equ.al to or rather larger than the diameter of the second antenna! joint, the 

 basal joint nalced ; considerably longer than the abdomen, composed of thirty-two or 

 thirty-three joints, of which from fourteen to sixteen form the club, which is elon- 

 gated, cylindrical, depressed a little, nearly equal for most of its length, increasing in 

 size only at its first two or three joints and on the last four or five diminishing rather 

 gradually to a bluntly pointed apex, the apical joint being exceedingly minute ; it is 

 fully throe times as broad as the stalk and about five times as long as broad. Palpi 

 slender, about half as long again as the eye, the terminal joint about three-quarters as 

 long as the penultimate and clothed with recumbent scales and a few hairs, the other 

 joints furnished profusely with large, long scales projecting on the under surface 

 but surpassed by a moderately heavy fringe of long hairs, all compressed in a vertical 

 plane. 



Patagia small, exceedingly long and slender, arched, and, excepting next theboi-ders, 

 tumid, a little more tlian three times as long as broad, the inner border nearly straight , 

 the basal half narrowing slightly, the apical half equal, less than half as broad as the 

 broadest portion, and terminating in a well rounded apex. 



Fore wings (39 : 13) about three-fourths as long again as broad, the costal margin 

 roundly and pretty strongly bent at a short distance from the base, beyond that 

 straight, very slightly curved l)ackward at the tip, the outer angle scarcely rounded ; 

 outer margin very slightly and regularly rounded, just above the middle of the wing 

 a little full in the J , its general direction at an angle of about sixty or seventy 

 degrees with the middle of the costal border; the inner margin straight, its outer 

 angle slightly rounded; costal nervure terminating a little beyond the tip of the cell; 

 subcostal with three superior branches, the first arising at or a little beyond the middle 

 of the upper border of the cell ; the second, two-thirds the distance from there to the 

 origin of the third, which arises just before the apex of tlie cell ; the main vein beyond 

 the origin of the third is curved downward to meet the cross vein, either slightly 

 and then continues in a straight course ( ? ), or pretty strongly and then springs back 

 to resume its former straight course ($) ; the cross vein is very feelily developed es- 

 pecially below ; cell a little less than half as long as the wing and about three times 

 as long as broad. 



Hind wings with the costal margin strongly convex next the base, beyond nearly 

 straight, outer angle varial)le, outer margin well rounded, very slightly prominent in 

 the naiddlc of the median region, at least in the ? , the tips of the middle and lower
