Described from a single female reared by H. G. Dyar, from larva? on 

 willow, collected at Jefferson, N. H. 



This species is closely allied in general appearance to my A. Comstocki 

 and A. gracilis, but differs in important colorational characters, and 

 seems intermediate between the two. It may be that ultimate rearings 

 will show that all three of these species, now apparently distinctly differ- 

 entiated, are merely varieties or indicate wide seasonal or local variations.
