the leaf around it also becomes stained of that hue. The larva is bright - 
gréen. Possibly this may be the V. difasciella Clem., but I can discern 
no trace of green in the wings. Dr. Clemens gives no measurements and 
“was not acquainted with the mine of #fasciella. He mentions, Proc. Ent. 
Soc. Phila., Nov., r86r, an empty mine in the leaves of the Wild Cherry 
as doubtfully that of a Vepricula, and possibly dipterous, and calls it W. 2 
Prunifoliella. As, however, he says that that mine begins in a blotch, 
_and as he was not acquainted with the insect in any of its stages, and it 
often happens that two or three species mine leaves of the same plant, I 
have not deemed it expedient toadopt his name. ‘The practice of naming 
species from an empty mine or even a larva, is a bad one, I think.
