The cocoon was leathery brown in color, of tongh, hard consistance, 

 lined within with silk. In form it was short oval, nearly spherical, 

 though still longer than the cocoons of the Cochlidinae, which it closely 

 resembled, thus showing the near relationship of the two subfamilies.

Our species, found in the Middle States, is of an uniform soft dark 

 sable brown. The body is .60 inch long, and the wings expand one 

 inch. I have received the cocoons of this species from Newbern, N. C, 

 through Mr. Shute,

This interesting genus seems to connect the true Psychida^ with 

 Perophora. It resembles this last named genus in its broad head, the 

 broadly pectinated antennte, the general form of the wings and in its 

 coloration, like that genus having but a single outer line common to 

 both wings and a discal dot upon each wing. 



This is a rare moth, and we look with interest for information con- 

 cerning its habits and trauformation.
