"Labial palpi pale brownish-red, touched ia front with pale gray. 

 Head and thorax brownish-red, the latter varied with grayish and dark 

 fuscous. Fore wings grayish-fuscous, with the costa touched with 

 brownish-red, and a patch of the same hue in the female, near the base 

 of the inner margin containing a tuft of raised scales; in the male, 

 blackish-brown, touched with brownish-red. The base of the wing is 

 whitish. In the middle of the wing is a broad white band, obsolete to- 

 ward the costa, with two straight blackish-brown lines internally, and 

 in the male shaded internally with the same hue. The subterminal line 

 is irregular and whitish, dark-margined internally. The hinder margin 

 of the wing is touched with blackish-brown. Hind wings pale brown, 

 somewhat darker toward the hinder margin. The larva is tortriciform 

 in appearance. Head pale brown, mottled with whitish. Body with 

 isolated hairs,'pale green, with a dark brown dorsal line and a fainter 

 stigmata! line of the same hue, or pale reddish, with a brown dorsal line 

 on each side of the vascular. It makes a web on the under surface of 

 the leaf of Sycamore [Flatanus occidentalis), drawing it together and 

 living within a silken tube. The cocoon is woven on the surface of the 

 ground, in form of a flattened oval, consisting of brown silk covered ex- 

 teriorly with grains of earth. The larvae remain in it unchanged during 

 the winter. It may be taken in July, and enters the pupa state during 

 the latter part of August, to appear as an imago in May or June." 



This species is probably equivalent to melitella of Zeller. 



Tetralopha aspcratella.

" Labial palpi blackish-brown, varied with whitish. Thorax pale gray- 

 ish, varied with grayish or dark gray. Fore wings dark brownish-gray, 

 with a blackish-brown tuft of scales in the basal part of the fold, and a 

 smaller one of the same hue on the disk above it, a whitish median 

 band, sometimes almost obsolete, containing on the disk a small black- 

 ish-brown tuft in the female, with an internal crenated blackish line, 

 and shaded toward the base with blackish ; on its external margin is a 

 line of raised scales. The subterminal line is pale grayish, angulated 

 and margined internally by a blackish line, and externally by a fainter 

 one produced into points on the nervules. The hinder marginal line is 

 black. Sometimes in the female base of the wing is whitish, slightly 

 touched with luteous." 



I have five specimens — two males and three females — before me. The 

 smallest measures 23 mil., the largest 28. They vary in the amount 

 of grayish-white on the median space of fore wings above.
