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.

 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, defined out- 

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

 running together into a line or obscure. 9 mm.
