sharp, sometimes obtuse rounded; outer margin rounded, inner 
margin rounded, generally slightly sinuate. Above, the most of 
the species have 2 crossbands of larger scales, which in places rise 
up into tuftings; two cross lines limiting the basal and middle 
fields. Beneath, 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 1 and the inner 
margin. In some of the species, in the males, a costal fold of coarse 
transverse scales extending from base sometimes */, the length of 
costa. Beneath this and partially or altogether hidden a vitreous spot. 
find wings, broad, nearly unicolorous, with rather indistinct anterior 
angle and rounded anal angle. 
Venation. 
Fore wings, 12- or 1i-veined, venation very variable, but 7, 8 and 
g always stemmed, 3 always separate. A peculiar feature is in 
the abnormal venation of those males which have the costal 
fold and vitreous spot on the fore wings; the ordinary plan of 
venation is essentially modified, the outer discal limitation being 
lost and the lower median being greatly widened and swollen. 
Hind wings, with 3 internal veins, and 8 veins in all, counting after 
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 
always before reaching base. Otherwise the venation is variable. 
Frenulum, single in <j, double in Q. 
Abdomen, cylindric, not tufted, with one exception. 
Genitalia. 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. Coxe broad, flattened, oval, broadest at base; femora 
flattened, stout; tibiz short, about '/, femora, tibial epiphysis near 
middle and less than */, tibiz in length. — rst tarsus as long as tibia, 
and about as long as the rest together ; femora sometimes tufted on 
end. 
Middle legs. Cox, femora and tibiz flattened-cylindrical, the tibiae en- 
larged at lower end ; tibiz with a pair of spurs at end ; tibiz a little 
shorter than femora; 1st tarsus nearly as long as the rest together.
