CHAMBERS ON FOOD-PLANTS OF TINETNA. 119 



CUPULIFEU^. 

 QUERCUS. Oak (various species). 



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

 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. 



Litliocolletis cincinnaUella, Cham. Yellowish blotch mine. 



LitlioGolletis Jiamadryadella, Clem. Whitish blotch mine. 



Litliocolletis tubiferella, Clem, t Mines somewhat like the track 



Litliocolletis hifasciella, Cham. ^ made by a drop of water as to form. 



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

 L. ulmella in Elm. 



Litliocolletis unifasciella, Cham. "} Irregular yellowish blotch mines, 



Litliocolletis hethuneella, Cham. )- smaller than that of cincinnatiella, 



Litliocolletis castaneceella, Cham. 3 ^^^ usually in Eed or Black Oaks. 



Tisclieria zelleriella, Clem. 



Tisclieria pruinoseella, Cham. 



Tisclieria castaneceella, Cbam. 



Tisclieria badiiella, Cham. 



Tisclieria quercivorella, Cham. 



Tisclieria quercitella, Clem. 



Tischeria citrinipennella, Clem. 



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



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



Tischeria tinctoriella, Cham. 



N epticula platea, C\em. ^ Imago unknown. Larvae of both in 



Nepticula anguinella, Clem. ^ crooked, linear mines. 



Nepticula quercipulcliella, Cham. ) 



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



Nepticula saginella, Clem. 3 



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

 tentiform 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 alhano- 

 tellay Cham, in the wwofer 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 lineina.)
