202 GROTE & ROBINSON. 



discal cell, enclose a continued and rather prominent pale streak be- 

 coming white towards external margin which it joins immediately be- 

 low the apex. Three pale ante apical dots on the ferruginous, costal 

 edge. External margin shaded with ferruginous and with a distinct 

 pale terminal line relieved inwardly evenly by the dark ferruginous 

 external shading and outwardly by the ferruginous base of the fringes. 

 A ferruginous shade on the interspace between first and second m. 

 nervules. Internal margin edged with deep ferruginous and with a 

 narrow ferruginous internal line running to the usual fragment of the 

 transverse posterior line which is distinct and angulated. The space 

 beyond this about internal angle is much shaded with ferruginous and 

 is limited superiorly by a prominent ferruginous outwardly ascending 

 shade streak. 



Secondaries darker, almost wholly blackish in the 9 ; in the opposite 

 sex they are obscure whitish from the base outwardly, the blackish ter- 

 minal shade narrowing in both sexes to anal angle. The "veins" 

 marked with dark scales; fringes pale. In shape the posterior wings 

 resemble the primaries in that the external margin is roundedly convex 

 at the middle. 



Beneath both wings are blackish; secondaries whitish over the base. 

 The primaries show three pale ante apical costal dots very plainly. 



Expanse, % 44, 9 49 mil. Length of hoily, % 20, 9 22 mil. 



Habitat. — Atlantic District. Imago flies in July and August, 



Easily distinguished from the described N. A. species of the genus 

 by the convex external margin of the wings, while the primaries above 

 are very distinct in appearance. 



DYOPS, Guenee. 

 Dyop's futilis, n. s. (Plate 3, fig. 73 % .) 



%. — Greyish fawn color. Antennae simple; maxillae stout. La- 

 bial palpi with the third article much closer scaled than the second, 

 elongate, subspatulate. Body parts concolorous, a little paler beneath. 

 Tarsi darker, subannulated. 



Primaries above smoothly scaled, concolorous with the thorax. 

 Transverse lines pure brown. Basal line indicated on costa; a brown 

 spot at the base of the cell. Transverse anterior geminate interrupted. 

 Orbicular spot appearing as a small brown maculation on the cell. 

 Beniform indicated by a brown interrupted annulus. Transverse pos- 

 terior line geminate, the brown lines wide apai't, interrupted, arcuated. 

 Beyond this the wing is thickly irrorate with black on a somewhat 

 paler ground color than the wing elsewhere; the external margin to-
