Head and thorax red-brown; anterior wings silvery -ash, with 

 an angulated red-brown fascia at the base, some large spots of the 

 same, forming an interrupted, oblique band from the costal to the 

 anal angle, and some smaller spots of the same on the hinder mar- 

 gin ; fringe red-brown : posterior wings fuscous, the apex darkest ; 

 fringe ochreous-brown. 



In the specimen described, the only one I have seen, the an- 

 terior wings appear to be narrowed, from the insect having been 

 killed too soon after exclusion from the pupa. — J. F. S.
