they belong. One of these, which was taken in the winter 

 time, hybernating under the loose bark of trees, is a Litho- 

 colletis, either Robiniella or Cratcegella, but possibly a new

 nistis, so much denuded and worn that I cannot determine 

 the species.

Hamadryas, n. gen. 



This imago, which I have placed in a new genus, appears 

 to me to be congeneric with a portion of the genus Gelechia. 



The hind-wings are lanceolate. The submedian and in- 

 ternal veins distinct. Subcostal simple, attenuated towards 

 the base. The disk is closed, and two nervules are given off 

 from it. The median vein is 3-branched. 



The fore-wings are lanceolate, with the inner margin 

 dilated near the base of the wing. The subcostal vein has 

 four branches, the first arising near the middle of the wing 

 and the apical nervule furcate. The disk is closed, with two 

 nervules given off from it. Median vein 3-branched, the 

 posterior branch arising midway between the space opposite 

 the origins of the first and second subcosto-marginal nervules. 

 Submedian furcate at the base. 



Head smooth, face and forehead broad. Ocelli very small. 

 Antennae rather thick, about one-half as long as the fore- 

 wings, denticulated beneath. Labial palpi moderately long, 

 curved, rather slender, smooth, pointed; the middle joint
