ANCYLIS ALBACOSTANA, new species. 



Head, on top, cinereous, mixed with ferruginou.s scales, a collar of 

 whitish next to thorax, in front brown. Palpi cream white; end.s of 

 scales of second joint, which conceal the third joint, dark brown; a few 

 scales of this color on outer sides of palpi. Antennae cinereous. 

 Thorax next to head a transverse band of lead color, another band of 

 this color crosses the middle, each followed In^ a band of whitish. 

 Patagia and thoracic tuft lead color at base, tips white. Fore wing 

 lead color, rather heavilj^ overlaid on inner two-thirds below the costa 

 with brownish and blackish scales. From the base to the apex on the 

 costa is a pure white band, widest at end of cell, where it is nearly a 

 a quarter the width of wing; continuing to base with onl}' a trifle less 

 width, and lower edge curving evenly into costa and ending in a point 

 at apex. Below the white streak, on the inner half, are a number of 

 small black dots; three below the fold are well defined, close together 

 in a line in the .second quarter; the inner one is single, the middle has 

 a slight projection on the fold, and the outer one is double, its upper 

 half being above the fold. Another black dot is on the upper gray 

 edge, and is conspicuous against the white background above its upper 

 half, before the inner fourth, and is connected by a darker streak with 

 the inner of the three dots below the fold. Many other darker trans- 

 verse streaks or strigulations cross the lead-color area. The ocellic 

 area and outer margin below apex are dusted with white, a small, 

 round, lead-color spot at anal angle and al)ove it a vertical flattened 

 ovate spot of same color; each are encircled by a line of whitish scales. 

 The apex and the streak between this paler area and the white costal 

 band is dark })rown; in the apex is a small ocellus, a circle of black 

 inclosing a dot of lead color and surrounded by dull ocherous. Cilia 

 at apex cinereous, tinged with ferruginous, below apex pure white. 

 Hind wings brownish fuscous above, pale fuscous below. Underside 

 fore wing fuscous, whitish streak repeated along costa, cilia white 

 below apex. Abdomen and legs fuscous, tarsi annulated with dark 

 l)rown. Expanse 19 mm. Two female specimens: OneTryon, North 

 Carolina, May 11, Fiske; one Colorado, National Museum, Accession

Coh/2)e.^.—C'dt. No. 821:6, U. S. Nat. Mus., and in my collection. 



In describing this species from two females I run the risk of a 

 generic error, but the falcate apex and venation agree with our 

 detinition of Ancylis.
