Notes on Some Species of Tischeria, with Descrip- 

 tions of New Species (Lep.). 

 By ANNETTE F. BRAUN, Cincinnati, Ohio. 



Under the names Tischeria badiiella and T. purinosella re- 

 spectively, Chambers described two species of Tischeria, both 

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

 II, 109, no, 1875). In regard to the mine of the former spe- 

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

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

 mine of the latter species he does 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 

 characteristics of the published descriptions of both species. 

 Badiiella seems to differ from purinosella 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 closely with the description of T. albo- 

 straminea 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 mentioned by Chambers in either de- 

 scription, is without exception present, even in the palest 

 specimens. 



The species should therefore be known as Tischeria badiiella 

 Chambers; T. purinosella and T. albostraminca will then sink 

 as synonyms. 



Tischeria immaculata n. sp. 



Head, including tuft and palpi, gray, tips of the scales white; an- 

 tennae gray. 



Thorax and fore wings gray, with the tips of the scales white, so 

 that the wing presents a uniformly speckled appearance under a lens. 

 There is no indication of other markings. Hind wings and cilia gray. 



Legs gray, scales white-tipped as on the fore wings, except the hind 

 tibiae and tarsi, which are pale yellowish. Abdomen yellowish, espe- 

 cially posteriorly. 



Expanse : 7.5-8 mm.
