 more or less upturned in front of the face ; third joint short, generally almost entirely-

 before end of cell, 11 free from 12 ; cell long, more than half the breadth of the wing, 

 vein 3 emitted close to or a little before the lower end of cell, 2 from before the middle, 

 except in Sehastonyma, when its origin is beyond the middle. Hlndwiiig with vein 7 

 emitted well before upper end of cell, except in Scobiira and Arvetta when its base is 

 near the end, discocellulars and vein 5 faint, vein 5 often nut tracealjle, 3 frum close to

Furewlng, vein 12 ends on the costa before the end of the cell, cell narrow, lonjr, 

 more than two-thirds the length of the costa ; upper diseocellular short, stronnh' 

 outwardly oblique, middle diseocellular upright, concave, slightly longer than the 

 lower, which is straight and slightly inwardly oblique, vein 5 arising from their 

 j.unction is consequently slightly nearer to vein 4 than to G ; vein 3 emitted some 

 distance Ijefore the lower end of the cell, 2 from near the Ijase of the wing ; sub-median 

 vein curved ; wing triangular, rather narrow, costa very slightly arched, apex somewhat 

 rounded, outer margin straight down Ijelow the costa, then inwardly olilique, hinder 

 margin straight, longer than the outer margin ; a large conspicuous patch of plush-like 

 modified scales on the middle of the underside of the wing. Hindiving, vein 8 gently 

 curved, ends at the apex of the wing, 7 emitted well before the upper end of the cell, 

 discocellulars and vein 5 faint, 3 from close to lower end of cell, 2 from beyond the 

 middle, cell about half the breadth of the wing, sub-median and internal veins straight ; 

 wing longer than broad, costa highly arched at the l»ase, then gently arched to the 

 apex, outer margin rounded, very slightly sinuous at the end of the sub-median vein ; 

 anal angle rounded, abdominal margin straight. Antennee long, more than half the 

 length of the costa of forewing, club moderate, ending in a pointed crook : palpi 

 upturned, second joint densely .scaled, third joint almost concealed ; fore tibiie with 

 epiphysis ; hind tibiae with two pairs of spurs.
