 Nepticula clemensella, Cham. I j^^^^ y 225. 



Cirrha platanella, Cham. Larva feeds on the under 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. 



JUGLANDACB^. 



JuGLANS NIGRA. Black Walnut. 



Lithocolletis carycefoUella., 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 

 mine 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 carycefoUella, Clem. As in Juglans nigra [supra). 



Carya alba. Hickory. 



Lithocolletis carywfoliella, Clem. See under Juglans nigra [supra). 



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

 under surface of the leaves. 



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

 it cuts out its pupal case. 



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

 drical case attached to the under surface of the leaves. 



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

 crooked mine on the upper side of the leaves. 



Ypsolophus carycefoliella, Cham, Larva sews together the leaves. 



Gracilaria, sp.? (probably G, blandella Clem.). Imago unknown. 

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