1. Lithocnllctes con'lolla. 

 a. Lithocollctes, lai-va. 



2. Ncpticnla aurella. 

 d. Ncpticula, larva. 



The larva is represented at Fig. ft, very much magnified. 

 When living it is about as long as the capital letter I, and 

 indeed, could not be much larger in consequence of the 

 character of its home. Its colour is pale yellow, with a 

 blackish-brown head, and a patch of deep orange upon the 

 ninth segment. It burrows into the leaves of the hazel 

 {Gorylus avellana), from which it obtains its specific name 

 coi'ylella.
