"Head and palpi thickly clothed with bristling brown and gray hairs, the 

 obtuse tip of the third joint of the palpi only visible ; antennae brown above, 

 the joints bordered with white beneath and within. Thorax and abdomen 

 beneath with long brownish hairs; legs brown with pale hairs at their joints. 

 Wings approaching those of N. persius in shape, but the primaries somewhat 

 narrower. 



Primaries umber-brown, mottled with black as in mnrlialis; near each 

 extremity of the cell, conspicuously marked with a large black spot, the 

 outer one having the hyaline white cellular spot on its outer margin. A row 

 of black spots cross the nervules, upon which are the following white hyaline 

 spots; four costo-apical ones, of which the costal one is scarce more than a 

 dot, the second the largest and quadrate, the third and fourth quite small 

 with their longest diameter in the direction of the breadth of the wing; in 

 cells two and three each, a triangular spot with the apex directed toward the 

 outer margin of the wing — that in cell two but partially hyaline; in cell lb, 

 two triangular spots (not hyaline), marked with white scales so obscurely in 

 the somewhat imperfect specimen, that possibly they may prove to be a 

 constant feature. Some white hairs and scales separate this row of black 

 spots from a subterminal row of rounded black spots, which is again sepa- 

 rated by a few similar white scales from the black terminal margin. Fringes 

 umber-brown, their base cut by some white scales projected from the black 

 margin. 



Secondaries fuscous, faintly marked by some brown spots and an indis- 

 tinct subterminal row of brown dots. Fringes snow-white with some brown- 

 scales of the terminal margin cutting their base, and at the apical angle of 

 the wing, extending nearly to their outer edge. 



Beneath, primaries pale brown, the hyaline spot in cell 3 showing conspic- 

 uously, and with white scales covering the extreme apical portion of the 

 wing. Secondaries reddish brown basally and medially, with a double row 

 of pale brown spots before the outer margin between veins lb and 4. Fringes 

 as above. Expanse of wings 1.38 inch. Length of body .58 inch. Habitat, 

 New Mexico. Described from one male in the collection of Mr. W. H. 

 Edwards." (Original description). 



"This species may be recognized among all those of the genus 

 known at present, by the white fringes of the secondaries, less 

 sharply defined at their base than in N. tristis, by its smaller size, 

 less pointed primaries and a less projected anal angle of the secon- 

 daries than in that species" (Lintner).
