3. saundersella. 

 2. Fore wing whitish gray, with contrasting blackish spots 1. attributella. 



1. E. attributella Walker. Hind wing with Mj running to apex, M 2 almost con- 

 nate with M 3 and Cu t , which are long-stalked; cell open. Powdery pearl white 

 (each scale fuscous and white). Palpi fuscous, tip of second joint and two bands 

 on third white; antennae dark. Fore wing with a large costal spot at base and one 

 rather beyond middle, a small one between them, and two or three less intense 

 ones on inner margin. Raised dark dots at end of cell and in fold. Apex lightly 

 spotted with fuscous. 10 mm. (difficilisella Chambers.) 



The moth is locally common, resting on the trunks of trees in July. 

 Massachusetts to North Carolina and Illinois. New York: Ithaca. 



2. E. subsimella Clemens. R and Mj normal. Head and thorax yellowish 

 fuscous; palpus with second joint brownish with a white ring at tip, third joint 

 white with outer half black; antennae dark, scape striped with yellowish in front. 

 Fore wing dark yellowish fuscous, brown along costa from the middle and toward 

 the tip; ground much sprinkled with white outwardly, a short yellowish white 

 streak at middle of costa and an angulate line at two-thirds way out; a blackish 

 spot below apex; and a dark streak in fringe. 8 mm. 



A southern species, doubtful in our territory. 



3. E. saundersella Chambers. Pale creamy yellow. Palpi with the two terminal 

 joints brown with white tips, and a band on the third. Head and thorax dusted 

 with blackish. Fore wing densely dusted below the fold, with three blackish 

 costal spots and two on disc, sometimes partly confluent into two oblique bands. 

 Apex heavily suffused; a dark line in base of fringe. Hind wing pale slate color. 

 7 mm. 



Kentucky. Types only known. 



4. E. geminella Riley. Cream white; a basal, blackish fascia of two partly fused 

 spots, and antemedial and postmedial fasciae of about three spots each; all three 

 parallel, and farthest out at costa. Fringe with a series of dark bars in base, and 

 preceded by a fuscous terminal spot. 



Larva on oak. 



Only a single specimen seen, in National Museum, and marked " rileyella type." 

 This is possibly the same as E. gallcegenitella Clemens, of which I have not 

 studied any authentic material. 



5. E. sylvicolella Busck. Fore wing dirty white, thickly dusted and shaded with 

 fuscous, and marked with black. No terminal dots. A raised, oblique, dark streak 

 near base, farther out on costa, and broken into spots on costa, fold, and inner 

 margin, sometimes obscure; another on costa two-thirds way out, denned out- 

 wardly by an outwardly oblique white line; and three bars along cell, sometimes 

 running together into a line or obscure. 9 mm. 



New York (Busck); Kentucky; Texas.
