Fore wings long and narrow, subfalcate; apex much produced, acute; costa 

 straight, sinuous; outer edge unusually oblique, very full, and rounded in the 

 middle. Hind wings verj much produced toward the subacute apex, so that 

 they are oval in shape, the inner edge being no longer than the outer. Vena- 

 tion: two equal subcostal cells; the three tirst subcostal venules short, but 

 the tirst much longer than the second; the discal venules are directed at right 

 angles to the costa. Hind legs very long and slender in the male; the tarsi 

 very long, equaling the tibia? in length. Abdomen long and slender. Color- 

 ation: dark-gray, with two broad double lines on the tore wings, the extra- 

 discal one toothed, with a double flexure; no markings on the dark hind wings. 



The acute, narrow subfalcate tore wings, and the narrow hind wings, 

 with the inner edge no longer than the outer, and the broad, full head, separate 

 this genus from any of its allies. The sexes differ considerably, the wings 

 being much narrower in the female than in the male. 



I see no reason for separating Anaitis from Carsia.

."> <?. — Front and palpi blackish, with white scales; thorax dark, with 

 light scales. Fore wings of a peculiar ash-color, dark on the outer edge and 

 on the base of the costa. A narrow band just beyond the basal third of the 

 wing narrower and less angulated than in the other species, being curved, and 

 just below the costa slightly angulated; on the costa and inner side it is 

 single, in the middle double, being within paler, dark brown. A similarly- 

 colored parallel band, but more irregular, externally in the middle of the
