silvery bands black-margined exteriorly, one beyond * the 

 middle toward the base, one about the middle and one near 

 the tip. A large black apical spot, with a few silvery scales 

 or minute spots; hinder-marginal line dark brown, cilia 

 reddish-orange. Hind-wings blackish, cilia blackish-brown. 

 Abdomen black. 



The larva mines the under surface of oak leaves, in Sep- 

 tember. I did not open the mines of the specimens I 

 secured, as I had but two. The larva w T as cylindrical, and 

 through the unruptured cuticle appeared to be of a lemon- 

 yellow colour. The pupa was contained in a very slight web 

 Avithin the mine. The imago appeared in May. The larva? 

 which I secured were taken in the leaves of the black oak on 

 September 23rd. 



(/'Ljuhl^ 11* L. Carycefoliella. Antenna? silvery, annulated with 

 blackish. Front silvery. Tuft and thorax reddish-orange. 

 Fore-wings reddish-orange, with three silvery bands, black- 

 margined exteriorly, the second about the middle of the 

 wing, angulated, with the black margin broad and produced 

 posteriorly on a whitish ground, nearly to the third, which is 

 somewhat interrupted in the middle; the first midway be- 

 tween the second and the base of the wing and also angulated 

 near the costa. The apical portion of the wing white, covered 

 with dispersed black scales, with a few black scales on a 

 whitish ground, on the costa, between the last silvery band 

 and the dusted apical portion; with two hinder-marginal 

 lines, one the margin of the apical scales, the other a dark 

 brownish line in the cilia. Hind-wings pale brownish-gray ; 

 cilia gray, with a fulvous hue. 



The larva mines the upper side of the leaves of the hickory 

 tree in June, July and September, making a white blotch, 

 or an irregular, rather broad tract when there is but one 

 in the leaf; and not throwing the leaf into a fold. Fre- 

 quently there are several larva? in a leaf; in one instance I
