sharp, sometimes obtuse rounded: outer margin rDundiHl, inner 

 margin rounded, generally slightly sinuate. Above, the most of 

 the species have 2 crossbands of larger scales, which in places rise 

 u]) into tuftings ; two cross lines limiting the basal and middle 

 fields, l^eneath, both sexes with the usual hair tuft receptacle in 

 which the frenulum is hooked ; a tuft or patch of coarse, not very 

 long, hairs at the base of the wing between vein i ami the inner 

 margin. In some of the species, in the males, a costal fold of coarse 

 transverse scales extending from base sometimes 7., the length of 

 costa. Beneath this and partially or altogether hidden a vitreous spot. 



Hind wings, broad, nearly unicolorous, with rather indistinct anterior 

 angle and rounded anal angle. 

 Venation. 



Fore icings, 12- or 11 -veined, venation very variable, tnit 7, Sand 

 9 always stemmed, 3 always separate. A peculiar feature is in 

 the abnormal venation of those males wliich have the costal 

 fold and vitreous spot on the fore wings ; the ordinary plan of 

 venation is essendally modified, the outer discal limitation being 

 lost and the lower median being greatly widened and swollen. 



Hitid 7vings. with 3 internal veins, and 8 veins in all, counting afier 

 the method of most of the great systematists and the method now 

 almost universally adopted ; cell short and closed, 8 reaches the 

 base, being joined with 7 by a short cross vein beyond the cell. Sub- 

 costal present, distinct near anterior angle, but becoming obsolete 

 alwa\s before reaching base. Otherwise the venation is \ariable. 



Frenulum, single in (j^, double in O. 

 Abdomen, cylindric, not tufted, with one exception. 



Geni/alid. Uncus prominent, slender, bent, furcate at base; inferior 

 lobe somewhat ladle-shaped, fringed on upper posterior margin 

 with stiff inwardly directed hairs ; side lobes rather prominent with 

 long hairs turned inwardly and sometimes with stout incurving 

 spine at base. 

 Legs, rather short, stout, generally loosely scaled, tarsi generally spin- 

 ulated, claw sharp, sickle-shaped. 



Fore legs. Cox^ broad, flattened, oval, broadest at base ; femora 

 flattened, stout ; tibia; short, al)out '/., femora, tibial epiphysis near 

 middle and less than '/-i tibiie in length. ist tarsus as long as tibia, 

 and about as long as the rest together ; femora sometimes tufted on 

 end. 



Middle legs. Coxa', femora and tibix- flattened-cylindrical, the tibia; en- 

 larged at lower end : tibia with a j^air of spurs at end ; tibia a little 

 shorter than femora : 1st tarsus nearlv as long as the rest together.
