Notes on Some Species of Tischeria, with Descrip- 

 tions of New Species (Lep.). 

 By Annette F. Braun. Cincinnati, Ohio. 



Under the names Tischrria badiUUa and T. purinoseUa re- 

 spectively. Chambers descrilxrd two species of Tischrria, both 

 of them miners in leaves of white oak (Cin. Quart. Jn. Sci., 

 II, 109, no, 187s). In regard to the mine of the former spe- 

 cies, he says that it is ustially placed near or at the edge of the 

 leaf, is whitish while fresh, becoming yellowish when dry. The 

 mine of the latter species he docs not characterize. 



Specimens of the only species having a mine of this appear- 

 ance that I have bred in the region of Cincinnati combine the 

 r1 >tics of the ptiblished descriptions of both spcdes. 



/} :>cems to differ from purinoseUa chiefly by the absence 



of the usual conspicuous dusting in the apex of the wing; such 

 specimens are rather rare in a bred series. On the other hand. 

 almost all of the specimens have the line of dusting along the 

 basal half of the dorsal margin. All of the specimens, how- 

 ever, agree much more closdy with the description of T. albo- 

 straminra Wlsm. (Proc. U. S. N. M.. XXXIII. 224, 1907). 

 whose mine on oak has been described by Mr. Busck (Proc. 

 Ent. Soc. Wash.. XI, 103. 1909). The small costal spot at 

 two-thirds, which is not mcntkmed by Chambers in eitber de- 

 scription, is without exception proent. even in the DaTest 

 specimens 



The ^)ecies shouki therefore be kno%im as Tisehtrta badUdla 

 Chambers; T. purinoseUa and T. athostrnminra wilt then sink 

 as synonyms. 



Tischeria immacuUta n. sp.

 tennae fray.
