colour is most decided. Cilia grayish-brown. Hind-wings 

 blackish-brown, cilia grayish-brown. 



Head and thorax white. Antennae, basal joint white, 

 annulated with black and white. Labial palpi white, dark 

 brownish externally. 



Case silken, covered with granulations. It is cylindrical, 

 slightly compressed, the mouth slightly deflexed and the 

 opposite end turned down slightly, hook-like. Colour brown, 

 varied with gray and reddish-brown granulations. 



I took the larva of this species on the 19th of April, feed- 

 ing on the opening buds of the common hundred-leafed 

 garden rose. During the winter, the case was attached to a 

 thorn on one of the principal stems. The imago appeared 

 on the 25th of May. 



Easton, Pennsylvania. 



Coleophora Rosacella, n. s. Basal joint of antennce slightly

 wings. Hind-wings blackish, cilia concolorous. 



Antennas, basal joint dark grayish-brown. Head and 

 thorax dark grayish-brown. Labial palpi grayish, grayish- 

 brown externally. 



The case is made of the cuticle of the rose-leaf on which 

 the larva feeds. It is a compressed cylinder, dilated slightly 

 on the middle of the under edge and serrated above. Colour 

 dark ochreous. 



I took the larvaa on the 19th of April, feeding on the 

 opening buds of the sweet briar, the leaf of which is strongly

 differs from that of the larva of the sweet briar ; it is smaller, 

 but of the same form, not serrated along the upper edge, and 

 with a slight projection on the middle of the under edge ; its 

 colour is grayish-brown. The cases of both are attached to 

 the thorns of the bush during the winter, or to one of the
