black scales ; anterodorsally a black spot near edge of tegula ; posterior 

 tuft fuscous. Forewing ground color light brown with slight pinkish 

 cast and with some ill-defined fuscous blotches; base of forewing buff 

 yellow, outer edge lobed obliquely to costa at one-third; an outwardly 

 oblique blotch of the same color separated from basal patch by an 

 arm of the ground color; costal edge of light basal patch brownish 

 ocherous ; basal patch and costal blotch overlaid with reddish ocherous 

 and sparsely irrorate with scattered jet black scales; outer third of 

 costa broadly edged with white, pink, and fuscous scales intermixed; 

 at end of cell a tiny white spot; around termen a series of blackish 

 spots; cilia fuscous. Hind wing buff to ocherous fuscous, veins out- 

 lined darker; anal area with darker scaling parallel to first anal vein; 

 cilia concolorous with hind wing but with some darker scales mixed. 

 Legs silvery white ; femur and tibia of foreleg strongly overlaid reddish 

 ocherous; midtibia overlaid ocherous and hind tibia faintly ocherous 

 dorsally. 



Abdomen fuscous dorsally, silvery white ventrally, latter with 

 slight buff tinge posteriorly; first sternum with strong, median, ever- 

 sible scale-tuft in male. 



Male genitalia: Harpe widest before middle, gently tapered to the 

 bluntly rounded cucullus; from base of harpe a broadly sclerotized area 

 extending almost to sacculus before middle and terminating in a small 

 pointed process; at middle of the sclerotized area, and arising from it, 

 there is a short, high ridge; from this ridge to costa, and beyond base 

 of harpe, there is a sclerotized subrectangular extension. Anellus 

 rectangular, slightly convex laterally. Aedeagus broadly U-shaped, 

 stout, terminating in a point bent dorsad; vesica armed with three 

 to five stout cornuti. Vinculum with well-developed dorsoanterior 

 process. Gnathos broad, transverse. Socii small hairy lobes. Arms 

 of uncus long, rather stout, somewhat dilated distally, connate at base. 



It should be noted that there is considerable variation in the harpes 

 and in the more strongly sclerotized areas of the inner surfaces; but 

 I do not believe that these apparent differences are specific. 



Female genitalia: Posterior third of ductus bursae strongly sclero- 

 tized. Inception of ductus seminalis dorsal, well before ostimn. 

 Signum a rather small dentate, elongate-ovate plate.
