7. A. rosaceana Harris. Costa and outer margin somewhat sinuous, but less so 

 in male than in male of A. purpurana, and strikingly less so in female, the sexes 

 being nearly alike in wing form. Strongly reticulate with brown; median fascia 

 clean-cut but not strongly contrasting, postmedian patch likewise; basal striation 

 transverse, or rarely, parallel to fascia, and not strongly curved. Hind wing of 

 male cream, somewhat shaded toward the inner margin with gray; in the female, 

 yellowish to bright orange, with the dorsal half contrasting gray. 20-28 mm. 

 (H. 48:32.) 



Common. Larva general on trees and shrubs; rarely, even on clover; sometimes 

 injurious to apple. 



General. New York: Common everywhere. 



A. hewittana Busck is unknown to me, and from the description I cannot dis- 

 tinguish it from A. rosaceana. It was described from Nova Scotia. 



III. Fold narrow, gradually fading out near middle of wing ; fringed more or less 

 with hair-scales beloic; generally forming a distinct flat tuft a third way out 

 on costa. 



8. A. rosana Linnaeus. Wings slightly sinuous before apex; sexes similar. Dull 

 brown, with slight greenish gloss; hind wing mouse gray, not contrasting; fascia 

 not strongly oblique, well marked, sharply defined on inner side; postmedial patch 

 continued by a strong subterminal stria toward anal angle. Striation sparse. 

 15-22 mm. 



Not very common. Larva a general feeder. 



Massachusetts to Missouri and Europe. New York: Thousand Islands, Albany, 

 West Farms. 



9. A. infumatana Zeller. Purple (as a strong iridescence on a blackish under- 

 color) ; base, a broad, well-defined fascia, and a subterminal streak reaching nearly 

 to anal angle, contrasting dark chocolate brown; all often defined with light 

 yellow brown; wing form of male like that of A. rosana; the female with more 

 strongly sinuous costa. 18-25 mm. 



July. Larva on hickory. "^ 



Connecticut to Missouri and Wisconsin. 



10. A. fervidana Clemens. Brown on basal half, gray on outer half, with heavy 

 and sparse ochre-yellow strise, partly edged with cream, and, especially outward, 

 centered with blackish, giving a general yellow-brown effect; dark patches on' costa 

 at middle and three-fourths way to apex, with yellow between them; a curved 

 blackish patch below outer end of cell, defined on inner side. Hind wing gray. 

 15-22 mm. (paludana Robinson.) 



July and August. Larva on oak; somewhat social; in small webs full of frass. 

 Generally distributed. New York: Ithaca. 



11. A. cerasivorana Fitch. Fore wing dull orange and when fresh, with purple 

 iridescence; hind wing immaculate bright orange. Male irregularly spotted and 

 speckled with dark red-brown, gathering into patches at middle and three-fourths 

 way out on costa, and below end of cell; female with more reduced speckling, or 

 nearly immaculate. 18-25 mm. (H. 48:21.)

 orange-red spots; two larger spots on costa; a spot a third way out, and a pair 

 two-thirds way out, on 'fold ; and a broken series of small spots near Outer margin ;
