2. Antemedial line very obscure and even 3. inquilinella. 



2. Antemedial line obscure and diffuse, but distinctly dentate .... 4. modestella. 

 1. Ground largely bright brown 5. rubrisparsella. 



1. N. ovalis Packard. Tuft on male antennae twice as large as scape in front 

 view. Powdery ash gray, rather coarse; the antemedial space typically, but not 

 always, brown or yellowish; antemedial line waved, denned on inner side by the 

 brown antemedial area, oh outer side mostly by a blackish bar at costa and dots 

 on veins; postmedial line normal, pale, only partly denned with blackish before it 

 and fuscous beyond, but with heavier black edges at costa; some blackish shading 

 near middle of wing; two black discal dots. Hind wing fuscous, not paler. 25 mm. 



Late July and August. 



Maine to California. New York: Rhinebeck, Delmar. 



Variety geminipunctella Ragonot, with ground largely white, was described from 

 Washington. 



N. fascicolella Hulst, described from British Columbia, is similar to N. ovalis, 

 but without any brown shading, and with only a little blackish shading along the 

 antemedial line. Tuft on antenna no larger than scape. 30 mm. A small form 

 of this (22 mm.) appears to occur in Labrador, and has been mistaken for 

 Polopeustis annulatella. 



2. N. rhypodella Hulst, another western species, almost evenly and very finely 

 powdered black and white, with traces of markings; has been reported from 

 Illinois. 



3. N. inquilinella Ragonot. Similar to N. modestella; the markings more diffuse, 

 antemedial band nearly erect and even. 18-24 mm, 



Larva in willow galls ( Salicis nodum ) . 

 Wisconsin. 



4. N. modestella Hulst. Tuft on antenna large. Fore wing fuscous, somewhat 

 dusted with white, especially about the end of the cell, and with a few black scales, 

 antemedial line pale, diffuse, well out, reaching the inner margin almost at the 

 middle of the wing, twice dentate, denned with blackish on outer side, especially 

 on the veins, and with a broad brownish band before it. Discal dots black, distinct 

 but not strong; postmedial line pale, normal, hardly denned with dark. Outer 

 part of wing slightly reddish shaded. 20 mm. 



Massachusetts. 



5. N. rubrisparsella Ragonot. Ochreous brown, more or less suffused with pinkish; 

 base solidly light; antemedial region suffused with blackish; antemedial and post- 

 medial lines luteous, black edged ; median area more or less shaded with black ; discal 

 dots black, strong; terminal space evenly pale, with black terminal dots, and a 

 line in the fringe. 18 mm. 



The typical form, from Texas, has the blackish shadings replaced with lighter 

 ash gray. I have not seen the male. 

 August. Larva on Celtis. 

 Jefferson County, West Virginia; Texas. 



84. TLASCALA Hulst 

 {Nephopteryx, in part) 



Similar to Nephopteryx. Fore wing with a more or less developed ridge or 

 scale-tuft before the antemedial line, sometimes with other markings more or less 

 raised. 



Key to the species 



Base of fore wing concolorous 1. finitella. 



Base of fore wing redder and darker 2. reductella.
