more strongly contrasted with the dark brown ground 

 than in N, Ncevius, but less so than in N. Juvenalis, — 

 about equal to N. Persius. The white hyaline spots of 

 the fore wings are of medium size, smaller than in the 

 average N. Juvenalis ; the spot in the discal cell is small ; 

 that in the upper median interspace on the transverse 

 band of sagittate spots is crescentic, concave towards the 

 base ; below this, in the second median interspace, is a 

 smaller white spot, wanting in some examples. The 

 four anteapical spots in the same band are not quite 

 in a line, as they are in N. Juvenalis, the third stand- 

 ing a little farther towards the base than the others; 

 the second and third being oblong, instead of quadrate 

 as in N. Juvenalis, 



There are fewer white scales on the fore wings than 

 in N. Juvenalis, there being scarcely any on the basal 

 side of the submarginal band, and only a few on the 

 outer side. The pale on the outside of the marginal 

 band is very dim. The usual two submarginal rows on 

 the hind wings are very obscure. 



Under side reddish brown, especially the hind wings, 

 which show two rows of pale brown submarginal spots, 

 which become obsolete before reaching the front margin 

 of the wing, and wholly want the white spots in cells 6 

 and 7 which characterize N. Juvenalis. The white spots 

 of the fore wings are larger than above. 



Head : above the eyes and just behind the " locklef' 



are a few white scales ; behind and beneath the eyes are 



some pale yellow-brown scales, and similar-colored hairs 



compose most of the palpal covering, in strong contrast 



with the dark brown color of the legs, thorax, and 



abdomen.
