Lithocolletis celtifoliella, Cham. Larva in a tentiform mine in the 

 uuder surface. Very rare. 



PLATANACE^. 



Platanus occidentalis. Sycamore, Buttonwood, Plane-tree. 



Nepticula platea, Clem. ] Larva of these three s l )ecies in tbe 



__ . , „ „,, upper surfaces of leaves. For descrip- 



JSepticula maximella, Cham. J> 



I tion of the mines and species see Can. 

 Nepticula clemensella, Cham. \ jg nt> v j25. 



Cirrha platanella, Cham. Larva feeds on the uuder side of the leaves, 

 and pupates in a tube composed of silk and the down from the leaves. 

 There is also an unknown larva, which makes a large mine, exactly like 

 that made by Coriscium albanotella Cham, in Oak leaves. 



JUGLANDACE^E. 



Juglans nigra. Black Walnut. 



Lithocolletis caryccfoUella, Clem. Larva in irregular blotch mine in 

 upper surface of leaves. (L.juglandiella Clem, is the same species.) 



Gracilaria blandella, Clem. Larva when small in a linear whitish 

 miue in upper surface of leaves; afterward feeding and pupating under 

 the edge of the leaf turned down. 



Gracilaria juglandisnigrceella, Cham. Larva at first mining the leaves 

 beneath ; afterward feeding and pupating under the edge turned up. 



Aspidisca juglandiella, Cham. Larva in a very small blotch mine, 

 from which it cuts out a case in which it pupates. 



Nepticula juglandifoliella, Cham. (& Clem.?). Larva in small, linear, 

 crooked mines; many on a leaf sometimes. Mine in upper surface. 



Juglans cinerea. Butternut. 

 Lithocolletis carywfoliella, Clem. As in Juglans nigra (supra). 



Carya alba. Hickory. 



Lithocolletis caryafoliella, Clem. See under Juglans nigra (supra). 



Lithocolletis carywalbella, Cham. Larva in a tentiform mine in the 

 uuder surface of the leaves. 



Aspidisca lucifluella, Clem. Larva in a small blotch mine, from which 

 it cuts out its pupal case. 



Coleophora carymfoliella, Cham. (& Clem.?). Larva feeds in a cylin- 

 drical case attached to the under surface of the leaves. 



Nepticula caryarfoliella, Clem. Imago unknown. Larva in a linear 

 crooked mine on the upper side of the leaves. 



Ypsolophus caryafoliella, Cham. Larva sews together the leaves. 



Gracilaria, sp.H (probably G. blandella Clem.). Imago uuknown. 

 The larva when young makes a linear whitish mine in the upper sur- 

 face of the leaves.
