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\
