CHAMBERS ON FOOD-PLANTS OF TINEINA. 119 



CUPTJLIFERJE. 



Quercus. Oak (various species). 



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

 that I have not attempted to arrange them according to the botanical 

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

 each larva. I have 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 the 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, t Mines 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. ~) Irregularyellowish blotch mines, 



Lithocolletis bethuneella, Cham. } smaller than that of cincinnatiella, 



Lithocolletis castaneceella, Cham. 3 and usually in Ked or Black Oaks. 



Tischeria zelleriella, Clem. 



Tischeria pruinoseella, Cham. 



Tischeria castaneceella, Cham. 



Tischeria badiiella, Cham. 



Tischeria quercivorella, Cham. 



Tischeria quercitella, Clem. 



Tischeria citrinipennella, Clem. 



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



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



Tischeria tinctoriella, Cham. 



Nepticula platea, Clem. ^ Imago unknown. Larvae 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 

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

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

 tella, Cham, in the under 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.)
