 the costa, and frequently its dark margin is not produced. A/, ex. )± in. 



Larva of the second group ; makes a flat mine on the upper surface of 

 leaves of Hickories (Carya), and when complete the mine is drawn into 

 a pucker along the middle. 



Wisconsin, Kentucky, Pennsylvania. Common. 



15. — L. tri-tcenianella. AT sp. 



Face and palpi white : tuft and thorax golden ; antennae white-banded 

 above with fuscous ; anterior wings reddish saffron, with three white fasciae, 

 each narrowly dark-margined internally, the first before the middle, the 

 second about the middle, and the third about half-way between it and 

 trie apex, and slightly angulated posteriorly. Apex slightly dusted with 

 brown on a white ground. Al. ex. about ^ inch. 



A single specimen, captured in April in Kentucky. Larva unknown.

Dr. Clemens describes this species as follows: — "Front silvery, with a 

 reddish hue ; tuft and thorax reddish orange ; antennae blackish brown ; 

 fore-wings rather deep reddish orange, with two silvery bands black- 

 margined behind, one in the middle nearly straight, the other midway 

 between this and the base of the wing obliquely placed. Before the 

 costo-apical cilia is a costal silvery spot, black-margined on both sides, 

 with an opposite dorsal spot black-margined behind. The apical portion 

 of the wing is dusted" (thickly so) " with dispersed blackish scales" (on 

 a white ground), "with a white silvery spot near the tip^ibove the middle 

 of the wing.' 1 (The position of this spot or streak is variable ; it is any- 

 where near the apex.) "'There are two hinder-marginal lines, one, the 

 margin of the dispersed scales, the other dark-brownish in the ciliae." 

 The costal and dorsal white spots near the apex are sometimes straight 

 and sometimes more or less oblique, and the dorsal one is frequently con- 

 fluent with the apical spot. Usually there is no basal streak, but frequent!) 

 the anterior margin of the thorax is pale, or even white, that color being 

 produced back over the tegulae to the base of the wings, forming a small 

 median basal streak which is occasionally dark-margined. The first fascia 

 is sometimes distinctly interrupted near the costa, and the second fascia 

 is sometimes dark-margined internally on the costa. Sometimes the costal 

 spot (near the apex) is faint, or even entirely wanting, Sometimes the 

 whole apical portion of the wing is dusted, and sometimes the dusting is
