Lepidoptera of New York and Neighboring States 403 



before anal angle; rich dark brown above, fading out below; its middle connected 

 to apex by another less regular brown shade. A longitudinal black bar in outer 

 part of cell and beyond, crossing the two brown fasciae. 14-18 mm. 



September 1. 



New York ; western States. New York : Hemlock Lake. 



23. E. heucherana Heinrich. Black-brown; fore wing with some white streak- 

 ing on the basal patch, a moderately broad, angulate antemedial fascia, and some 

 white streaks on outer part of costa. Fringe with a black basal line; smoky 

 fuscous, cut with white below apex. Hind wing very dark brown, with paler 

 fringe. Head with white face, and base of palpi. 10-13 mm. 



This may be a race of the western E. ruidosana Heinrich, from the same food, 

 but it shows a genitalic difference. 



Larva in a digitate mine in leaves of Heuchera americana; deep red, with 

 black head and cervical shield. Moth in May and June. 



Rosslyn, Virginia ( near Washington ) . 



8. ANCYLI8 Hiibner 



(Ancylopera, Phoxopteris) 



Eyes moderate; palpi porrect, somewhat' rough-scaled, or more rarely quite 

 hairy, often clavate, large. Wings smooth-scaled. Fore wing falcate, the outer 

 margin usually concave from above Mi to Cui; the concavity variable in character, 

 but sharp and deep, as in Eudemis. All veins free; M 2 -Cu! more or less approx- 

 imate at margin. Hind wing with M 3 and Cu 2 connate or stalked. 



Valve slender; cucullus sharply denned, slender; anal indentation usually broad 

 and smooth; sacculus only sparsely spined; costal hook weak or absent. Uncus 

 variable, bifid when present; socii very broad and hairy; gnathos slight, fused. 



I use the names Ancylis and Anchylopera as indicated by Walsingham and 

 Durrant. In this country they have sometimes been interchanged, or, more often, 

 the genera have been united.
