are two brown basilar spots resting on the subcostal and 

 median veins, not so dark as those of the disk. The 

 discal band, usually continuous in this genus, here con- 

 sists of three elongate fuscous dashes (appearing to the 

 unaided eye as a single spot) resting on the subcostal 

 near the discal cross-vein, extending nearly half-way to 

 the median, the intervening space having merely an 

 indication of the spot, which appears distinctly in most 

 of the species as the inner cellular tooth of the discal 

 band ; following this is an obscure fuscous spot at the 

 fork of the first and second median venules, and, beyond, 

 the usual hour-glass-shaped spot, extending from the 

 second median venule to the submedian, with its con- 

 striction on the interspaceal fold. The discal cross-vein 

 is conspicuously marked in brown. The submarginal 

 band of fuscous spots is doubly curved, being convex 

 towards the outer margin from the costa to the third 

 median venule, thence concave to its termination at the 

 submedian. It consists of four acutely ellipsoidal fus- 

 cous spots between the subcostal venules, which are 

 wholly destitute of the usual hyaline spots, followed by 

 three others of similar form but of greater breadth, the 

 next subacute externally, and the last similar in outline 

 to the corresponding one of the discal band. There is a 

 marginal row of interspaceal brown spots, the first four 

 of which are surrounded by gray scales and lie near the 

 margin, and the remaining four more remote than in N. 

 Martialis ; also a row of obscure brown spots resting on 

 the tips of the venules and extending on the fringe. 



Hind wings of a darker ground than the fore wings, 

 sprinkled with blackish scales, darker basally, and with 

 pale yellow-brown spots. Discal spot and marginal row
