rcous or oclireoiis, irroratod or strii;ulated witli brown or fus- 

 cous or whitish; first and second lines ochreous, sometimes al- 

 most obsolete, first line strongly cnirved outwardly, second line 

 sinuate with a slight curve outward before middle and a strong 

 curve inward below vein 2, included median band sometimes 

 wholly and sometimes partially black-edged ; often considerable 

 whitish suffusion beyond second line ; usually a series of black- 

 ish dots beyond second line extending from costa about half way 

 across wing; orbicular represented by a black dot; reniform 

 by a transverse blackish mark. Hindwings cinereous or pale 

 greyish-fuscous; a faint darker discal mark. Legs cinereous- 

 fuscous. 



A variable species closely related to N. ohsoleta (Butl.), but 

 differing particularly by the first line of forewing being more 

 strongly curved, and the second line strongly sinuate.
