CHAMBERS ON FOOD-PLANTS OF TINEINA. 119 



CUPULIFERiE. 



Quercus. Oak (various species). 



(Different species of Oak are so frequently fed on by tbe same larvae, 

 that I bave not attempted to arrange tbem according to tbe botanical 

 species, since that would cause too frequent repetition of tbe account of 

 each larva. I bave therefore arranged them simply as miners of the 

 upper and lower surfaces of the leaves, with an occasional note as to 

 the species of Oak fed upon by tbe larva. The species which feed ex- 

 ternally are arranged separately, following the leaf-mining species.) 



Leaf-miners of the upper surface. 



Lithocolletis cincinnatiella, Cham. Yellowish blotch mine. 



Lithocolletis hamadryadella, Clem. Whitish blotch mine. 



Lithocolletis tubiferella, Clem. ) Miues somewhat like the track 



Lithocolletis bifasciella, Cham. \ made by a drop of water as to form. 



Lithocolletis bicolorella, Cham. Yellowish blotch mine, like that of 

 L. ulmella in Elm. 



Lithocolletis unifasciella, Cham. ") Irregular yellowish blotch mines, 



Lithocolletis bethuneella, Cham. )■ smaller than that of cincinnatiella, 



Lithocolletis castaneceella, Cham. 3 au< l usually in lied or Black Oaks. 



Tischeria zelleriella, Clem. 



Tischeria prtiinoseella, Cham. 



Tischeria castanemella, Cham. 



Tischeria badiiella, Cham. 



Tischeria quercivorella, Cham. 



Tischeria quercitella, Clem. 



Tischeria citrinipennella, Clem. 



Tischeria complanoides, Frey & Boll. (Doubtful species.) 



Tischeria concolor, Zeller. (Food-plant uncertain.) 



Tischeria tinctoriella, Cham. 



Nepticula platea, Clem. } Imago unknown. Larvse of both in 



Nepticula anguinella, Clem. ^ crooked, linear mines. 



Nepticula quercipulchella, Cham. ) 



Nepticula quercicastanella, Cham. j> Larvae in crooked, linear mines. 



Nepticula saginella, Clem. 3 



Coriscium. Imago unknown. The larva, iu Colorado, makes a large 

 tentiform mine in the upper side of tbe leaves, which is almost a fac- 

 simile of that made iu the Ohio Valley by the larva of Coriscium albano- 

 tella, Cham, in the tinder surface of the leaves. 



Goleophora querciella, Clem. Imago unknown. The larva lives in a 

 case which it attaches to the leaves. 



Catastega timidella, Clem. Imago unknown. Larva at first mines the 

 leaves, and afterward lives in a tube made of "frass". (?Not a Tineina.)
