THE CANADIAN ENTOMOLOGIST. 91 



Beech (Carpinus Americana), is this species. In all the specimens, 

 whether bred from Hazel, Iron-wood or Water Beech, the fasciae are 

 scarcely or not at all curved, but are placed obliquely across the wing and 

 are nearest to the base of the wing on the dorsal margin. I have found 

 it more abundant on the Water Beech than on either of the other food 

 plants. It, and indeed all the species feeding on these plants, are very 

 different from the European species feeding on allied plants and mentioned 

 above, and from Carpinicolella. 



Z. Clemensella Cham. 



The suggestion elsewhere made that the mine and larva of this species 

 in Maple leaves might perhaps be distinguished from those of Z. lucidi- 

 costella Clem., by finding that this species pupates in a cocoon of frass, is 

 not supported by the facts. I know of no way in which the species can 

 be distinguished in their early stages. 



L. ostrycefoliella Clem. 



Dr. Clemens' description of this species is exceedingly inaccurate, so 

 much so that captured specimens would scarcely be recognised in it. The 

 same is true, likewise, of his description of L. obscuricostella. Both of 

 these species make small tentiform mines on the under side of Ostrya 

 leaves. No other species is known to make similar ones in these leaves. 

 Bred specimens may therefore be recognised in the descriptions. 



Z. juglandiella. 



Dr. Clemens bestowed this name upon a species known to him only 

 by the larva and mine, suggesting that it might not be different from Z. 

 carycefoliella Clem. • and in a former volume I stated that it was caryce- 

 foliella in my opinion. Since then I have succeeded in rearing the imago, 

 and find that we were not in error in this respect. It is carycefoliella. 

 Carycefoliella is a very variable species, as I have stated in Vol. 4, and is 

 very difficult to rear, especially from the Walnut-feeding larva. 



Z. qrnatella Cham. 



I have bred great numbers of this species and find no variation in the 

 fasciae and marginal streaks, though the ground color of the wings varies 

 from those in which the basal portion is maroon brown, as stated in the 

 description, to those in which the entire wing (except the dark margins 

 of the streaks and fasciae) is bright golden.
