NORTH AMERICAN EUCOSMINAE. 191 



20. NORMA, new genus. 



(Pigs. 33, 414.) 



Genotype. — Epinotia dietsiana Kearfott. 



Fore wing smooth; termen deeply concave just below apex (be- 

 tween veins 5 and 6); apex pointed but not falcate; 12 veins; 7 

 and 8 closely approximate; 10 from cell rather nearer to 9 than to 

 11; 9 approximate to 8; 11 from middle of cell; upper internal vein 

 of cell from between 9 and 10; 3, 4 and 5 closely approximate at 

 termen; 2 bent up slightly toward termen; no costal fold in male. 



Hind wing with 8 veins ; 6 and 7 approximate toward base ; 3 and 

 4 stalked. 



Male genitalia with harpe simple; several very long spines on 

 cucullus arising near costal margin and neck of harpe; sacculus 

 densely clothed with long hair-like spines. Uncus bifurcate; arms 

 widely separated, weakly chitinized. Socii long; broad; ribbon- 

 like. Aedoeagus straight; moderately long; stout. 



A monotypic genus closely related to Kundrya and Rhofobota. 

 The three are probably derived from the Epinotia stem but in the 

 development of the uncus are like nothing except perhaps Griselda. 

 The socii and gnathos are more as we find them in Eucosma,

I have reared this species from Ilex verticillata along with speci- 

 mens of both Rhopobota ilioifoliana Kearfott and Kundrya fmti- 

 muma Heinrich. The three are apt to be confused but can be easily 

 separated on structural characters, the condition of veins 7 and 8 

 of fore wing being alone sufficient to distinguish them apart. 



Male genitalia figured from cotype in National Collection from 

 Hazleton, Pennsylvania (" 5/30 "). 



Distribution according to specimens in National Collection, Ameri- 

 can Museum, and collection Barnes : Pennsylvania, New Hampshire,

Alar expanse. — 10-15 mm. 



Type. — In American Museum, 



Type locality. — Hazleton, Pennsylvania. 



Food plant. — Ilex vertidllata.
