Imago. — 2 J' , 29. Head visible from ;il)ove; front moderately wide; psilpi very short, 

 niiixilhe not visible. Anteniiie of S with short joints; bipectinate on the basal three-fourths, 

 tip tiliform, but the sinjj-le pectinations are distinct, quite well developed, though not ending- in 

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

 well developed to a little be3'ond the middle, the longest pectinations being nearly twice as long 

 as the joint bearing them; the tilifonii 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 olituse, outer edge 

 full and convex, inner angle much rounded. The two sexes are much alike, so that it is difficult 

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

 Isabella brown, with thick-set, dusky strigie. Basal line obsolete, extradiscal line faint, diffuse, 

 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 ([uite reaching to end of the abdomen in either sex; pale or 

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

 one $ 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 diffuse 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 

 t? somewhat flattened, tufted at the end; in l)oth sexes pinkish above and lieneath. 

 Legs dark; fore legs of S with a broad, tlat leaf-like tibial sack, sharp at the end 

 and about half as long as the tibia itself. (For the venation see Fl. L^'II, tigs. 

 1, \iU 1?-.) 



Expanse of fore wing.s — S 60-7.5 mm.; 9 TiS mm. Length of a fore wing — 

 i 26-35 mm.; 9 34 mm. Breadth of a fore wing — $ 13-15 mm.; 9 IS mm.; 

 length of hind wing — S lS-2-1 mm.; 9 22 mm. Breadth of hind wing — $ 

 14-15 mm.; 9 15 mm. 



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 antenniBare pectinated and the other secondary .sexual characters are 

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

 being full and thick; the hind wing in both sexes is of nearly the same size and 

 the coloration is the same. 



Gi'ograjihlcal dixtribntlon. — New Jersey (a single specimen taken on the coa.st. 

 Smith); Iowa (var. f<>ij»-<7ii(i). Cedar Eapid.s, Iowa (G. H. Berry); Columbus, Ohio 

 (W. N. Tallant); Dayton, Ohio (Jewett); Kentucky; North Carolina (Harris); Arkan.sas (Grote). 

 Not reported from Mexico. (See Map I.) 



This species is evidently distributed throughout the southern Appalachian subprovince, and 

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

 into Texas and Mexico. 



Edwards's var. imiiiaeuhita S and 9 . only differ, as ] tind on examining his types in the 

 American Museum of Natural History, in the speckles being obsolete, though in the i there are 

 traces of them to be seen. Thev are from Davton. Ohio.
