brown centres. The marginal row of brown spots lacks 

 the gray crescents, there being only mere traces of them, 

 and are not set in a grayish field, there being some bluish 

 scales inside this row over most of the wing, but none 

 outside ; and there is not so much difference between the 

 color of the end of the cell and the rest of the wing as 

 in N. Persius. Hind wing with only traces of spots in 

 the usual places. 



Under side a little paler brown than the upper, all the 

 hyaline spots distinct. The marginal and submarginal 

 bands of the fore wings are dimly outlined, the outer set 

 in a paler ground. The usual double row of spots on 

 the hind wings is dim. 



The male differs from the female in having the bands 

 and hyaline spots less distinct, and the ground color a 

 little darker.

Expanse of wings from 1.3 to 1.6 inches. 



Upper surface dark smoky brown, so dark that the 

 usual bands are a little obscure. These are the mesial 

 and submarginal bands of spots on the fore wings, and 

 an obscure spot at the base of the cell. The mesial band 

 would be obscure were it not for the few gray scales that 

 border the spots. The upper point in the cell contains 

 a small hyaline spot. The submarginal band contains 

 five or six hyaline spots, the first four situated in spots 

 1 to 4 of the band, and the fifth in spot 7. The spots 

 of this band are shorter and less pointed than in N. 

 Persius and N. MartiaMs, the last two scarcely united ;
