17 J. — Body and wings, including the head and palpi, uniformly tes- 

 taceous or dull ochreous-brown. Wings thin, semi-transparent. Fore wings 

 with about eight well-marked scalloped lines, the points of the scallops black, 

 and usually resting on the veins. The middle and extradiscal lines are curved 

 outward just below the costa, the three extradiscal lines being close together 

 and forming a mesial shade on the wing, but the three submarginal lines 

 beyond are not curved. Discal dot distinct and black. Fringe concolorous 

 with the wings, with black vcnular dots. Hind wings clear, with a faint 

 extradiscal diffuse line curved opposite the distinct discal dot; this line is 

 often obsolete: beneath, this and the extradiscal line make a diffuse shade 

 common to both wings. Discal dots distinct on both wings. 



Length of body, <?, 0.32-0.48; fore wing, $ , 0.46-0.65; expanse of 

 wings, 0.95-1.30 inches. 



9. — The female has not yet occurred in collections in this country. 



A single female boreata, so labeled by Zeller, is pale gray, with simple an- 

 tennae. The front of the head is dark brown or chocolate-color; the palpi at 

 base concolorous with the body, the last joint chocolate-brown, and both pairs 

 of wings are rather large and broad, rounded at the end with a long fringe and 

 reaching to the apical fourth of the abdomen. The legs are gray, and the 

 hinder pair are rather stout. The front wings have two parallel black lines, a 

 little oblique; and the distance between them as great as half the width of the 

 wing. The single female brumata differs in the slenderer body, the narrower 

 head, the shorter narrower wings, the two parallel bands on the anterior pair 

 being represented by a broad black patch; the wings only reach as far as the 

 middle of the abdomen. The legs are slenderer, particularly the hinder pair, 

 which are dark-ringed, with a paler tint; but this specimen seems fresht'r 

 than the boreata, in which the color of the legs bears the marks of being faded. 



From the female of Anisqpteryx, it differs in the broader, less full, bulg- 

 ing front of the head, the quite well-developed wings, and the stouter hind
