hiiiKjii. — 2c?. 29. Head visible from above; front moderately wide; palpi very short, 

 maxilhe not vi.'sible. Aiiteiin;e of S with short joints; bipectinate on the basal three-fourth.s, 

 tip Hliform. but the sinolo pectination.s are distinct, (juite well developed, thoiig-h not ending in 

 a seta; in 9 antenna- unipectinate. i.e.. the pectinations of basal pairs thick, subclavate. and 

 well developed to a little beyond the middle, the longest pectinations Ijeing nearly twice as long 

 as the joint bearing them; the filiform tip with minute teeth. Head, thorax, and fore wings 

 ocherous or Isabella, often pinkish ocherous. 



Fore wings with the costa more convex on the outer half than usual; apex oljtiise, outer edge 

 full and convex, inner angle nuich rounded. The two se.^s are much alike, so that it is dithcult 

 to distinguish them by the shape of the wings or their coloration. Fore wings ocherous or 

 is.ibella brown, with thick-set, dusky striga?. Basal line obsolete, extradiscal line faint, diftuse, 

 dusky, sinuous, ending on the costa rather far from the apex; it is interrupted by the veins. In 

 one $ the wing beyond this line is pinkish. Two distinct conspicuous white discal 

 dots, varying in size, those on the same wing not equal in size; sometimes one 

 or all are nearly obsolete or wanting. 



Hind wings not quite reaching to end of the abdomen in eitiier sex; pale or 

 dark roseate; paler, almost ocherous on the outer margin and on the costa; in 

 one i the pink is of a rich and dark color, deepening in hue toward the base of 

 the wing. 



Underside of fore wings deep roseate, paler beyond the diS'use extradiscal line 

 and on the costal edge ocherous. Hind wings pale pinkish ocherous. clear, with 

 large, dusky striga-. No discal spots on the wings of either pair. Abdomen of the 

 $ .somewhat flattened, tufted at the end; in both sexes pinkish above and beneath. 

 Legs dark; fore legs of $ with a broad, flat leaf-like titiial sack, sharp at the end 

 and al)out half as long as the tibia itself. (For the venation see PI. LVII. tigs. 

 1. \<i, \}).) 



Expanse of fore wings — $ 60-75 nun. ; 9 TH mm. Length of a fore wing — 

 $ 26-?.5 nun.; 9 ?A mm. Breadth of a fore wing — $ 13-1.5 mm.; 9 18 mm.; 

 length of hind wing — $ lS-24 mm.; 9 -'2 mm. Breadth of hind wing — Z 

 14-1.") nan.; 9 15 nim. 



It varies in the ocherous hue of the fore wings, in the pink hue of the hind 

 wings, and in the-presence or absence of the discal dots, though they are usually 

 present, and in the presence or absence of the extradiscal line. 



The 9 antenna? are pectinated and the other secondary sexual characters are 

 slight Iv developed. The body of the male is feminine in appearance, the abdomen 

 l)eing full and thick; the hind wing in both sexes is of nearly the same size and 

 the coloration is the same.

This species is evidently distributed throughout the southern Appalachian sui>province. and 

 with little doubt ranges over the entire Austroriparian subprovince. and may be found to extend 

 into 'j'exas and ilexico.
