ture, but have a serrated appearance caused by rings of 

 slightly elevated scales. The lateral claspers slender, 

 attenuated near the base, dilated downwards beyond ; 

 their upper edge being nearly straight, the tapering ends 

 evenly rounded and slightly bent inwards. The uncus 

 is single, with the point short and very little bent over. 

 On re-examination of the cell of the hind wings I find 

 a slender nervure closing it at the end.

'• Labial palpi reddish brown. Thorax dull brown, tinged with 

 reddish. Fore wings rubescent and maroon-brown intermixed, the 

 former hue prevailing along the fold, at the base along costa and 

 disc, dusted with dark brown ; with a dusky or dark brownish spot 

 on the end of the disc, one about the middle of the fold and 

 another near the base. In some specimens these spots are quite 

 indistinct. Hind wings dusky brown. Exp. al. 17 lines ( = 3Grnru.) 

 Females not known." 



To this description we rnay add that the antennae are compressed, 

 not strictly serrated throughout, but only slightly so towards the 

 tip ; lateral claspers spoon-shaped, rather abruptly dilated and bent, 

 with a pair of supplementary claspers above them, nearly as long 

 as themselves ; uncus double, the points parallel and divided. 



I have four females from North Carolina, of which the 

 following is a description : — 



Labial palpi extended straight out beyond the head, roughly 

 clothed but tapering to a point. 5 mm. long. 



Fore icings full 6 mm. wide, with the costa slightly rounded ; 

 the apical margin also convex. Exp. al. 35 mm. 



I have a considerable number of males from North 

 Carolina which agree with a specimen compared with 

 the type at Philadelphia in 1871. In Zeller's series are 

 four specimens ; two from Massachusetts, sent by Mr. 

 Packard and labelled "bombycina, Z." : a third from 

 New York, with a label in Mr. Grote's handwriting, 

 "plumifrontella, Clem."; the fourth is labelled "bomby- 

 cina " in Zeller"s writing, and is a female, evidently of a 

 different species, from Buenos Ayres, received from
