the inner border, by a fjentle, rather re<jiilar curve, wliich follows the 

 outer bonier of the cell; l)esi(los, there is a small roundish patch at 

 tlie extremity of the cell itself, separated from the part outside by 

 the nervures. On the hind wings it is of less extent, its interior 

 border passing in a broad sinuous curve from the tip of the costal ner- 

 vuretothe middle of the lower median interspace, where it terminates 

 abruptly; the band is broadest beyond the cell, reaching two-thirds 

 the distance from the outer border to its outer extremity; the fringe 

 is concolorous, but its basal half is black below the middle subcostal 

 nervure. Beneath, both wings are uniform, inunaculate, very pale 

 silvery buff. Expanse of wings 70 mm. 



I have not seen the female. Tehuan tepee. 



This butterfly is undoubtedly most nearly allied to A. Neleis 

 (Boisd.) Butl., but differs from it in the coloration of both surfaces, 

 the black edging of the fore wings and the secondary mealy patch 

 of scales in the cell of the same wings.
