upper surface of inner margin of hind wing and along the upper 

 and lower margins of the cells on the underside of both fore and 

 hind wings. 



I make this genus with considerable reluctance, but there is no 

 other way possible. In hind wing venation it should fall into the 

 Olethreutinae, but the notched termen of fore wing and the genitalia 

 as well as the pattern shows it to be a primitive Gretchena derived 

 from the stem of Epinotia and still retaining a strong costal fold. 

 In genitalia it differs from Gretchena only in having broader, 

 shorter, more wealdy chitinized socii. 



GWENDOLINA CONCITATRICANA, new species. 

 (Figs. 32, 323.) 



Antenna fuscous brown; basal joint black on inner side. Palpi, 

 upper face, head and thorax sordid fuscous; inner sides of palpi 

 sordid whitish; lower face dirty ochreous white. Fore wing 

 sordid ochreous-fuscous marked with black scaling; a faint indica- 

 tion of a dark basal patch chiefly determined by a blotch of black 

 scaling in cell near base of wing; over ocelloid patch a streak of 

 black scaling connecting with a similar short streak on outer upper 

 margin of cell; on outer half of costa four or five short blackish 

 fuscous dashes, that at apex most conspicuous; ocellus indicated by 

 a paler square of the ground color; a similar pale spot on dorsum 

 before tornus; cilia dark fuscous with a couple of very faint pale 

 dashes below apex. Hind wing smoky fuscous; cilia smoky with 

 a pale median shade and a very fine pale line at base. 



Male genitalia figured from type. 



Alar expanse. — 14-17 mm. 



Type.—Q^X. No. 24839, U.S.N.M. 



Paratypes. — National Collection, American Museum, and collec- 

 tion Barnes. 



Tyjye locality, — Kerrville, Texas. 



Food plant. — Unknown. 



Described from male type and 4 female paratypes from Kerrville, 

 Texas (F. C. Pratt, June and July) ; one male paratype from Hazle- 

 ton, Pennsylvania ("T-22-06") ; one male paratype from Philadel- 

 phia, Pennsylvania (" 5-1 ") ; and one female paratype from Jeffer- 

 son County, West Virginia (W. D. Kearfott, "VIII-1"). The last 

 three are from the Kearfott duplicates ; one of these he had set aside 

 as representing a new genus.
