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 very 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 first subcostal venules short, but 

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

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

 very long, equaling the tibiaj in length. Abdomen long and sleiuhjr. Color- 

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

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



The acute, uai'row subfalcate fore wings, and the narrow hind wings, 

 witli the inner edge no longer than the outer, and the l)road, full head, separate 

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

 being much narrower in tlie female than in the male. 



I see no reason for separating Aiiaitia from Carsia.
