tiiict pale gray streaks; the curved streak is margined behind indis- 

 tinctly by pule gray, and on the costa, between the curved streak and 

 the first straight, oblique streak, is a minute white streak, margined all 

 around by a narrow, dark brown line ; the first straight, oblique sti-eak 

 is margined behind faintly by pale gray, and the third (narrow) oblique 

 streak is margined behind by a narrow, faint, metallic white streak, which 

 passes obliquely backward to the middle of the apical part of the 

 wing. At the apex is a circular brown spot, which has a small white 

 costal streak or spot before it, and also an opposite dorsal one, and is 

 margined behind by an almost semi-circular, narrow, white line, along 

 the base of the cilia, which are dark brown at the apex ; the dorsal 

 cilia are pale gray. The apical spot is thus, by means of the semi- 

 cular line and the opposite costal and dorsal streaks, entirely surrounded 

 by white, except in front, and partly on the costal margin. The dor- 

 sal margin of the wing is largely margined with white, especially near 

 the base ; just within the basal fourth is a very small, dorsal, white streak ; 

 another, a little larger, is placed just before the middle; just behind the 

 middle are some indistinct, zigzag, brown lines, partly margined with 

 white ; about the apical fourth is a very oblique, slightly curved, dorsal, 

 white streak, dark margined behind, and extending around and beyond 

 a small dark brown dot, just before the cilia. Al. ex., one third inch. 

 A single specimen received from Miss Murtfeldt, who informs me that 

 the larva curls down the edge of oak leaves. In its earlier stages it is, 

 probably, a leaf miner. 



Nepticula,— JV. castanccafoUeUa (n. sp.) 



This species makes a linear, crooked mine on the upper surfoce of 

 leaves of the chestnut (Castanea aviericana). The larva is bright 

 green, and the mine has a distinct central line of frass. 



The imago has the palpi, vertex and eye-caps creamy white ; 

 head dark brown ; thorax and primaries dark purple brown, with pale 

 ciliic. Posterior tibije and anterior legs, except the femora, dark brown ; 

 legs otherwise sordid whitish, silvery tinged ; abdomen greenish above, 

 beneath whitish, margined with fuscous along the sides ; antennae brown 

 above, pale fuscous beneath, and very faintly annulate with while. AI. 

 ex., ~2 inch, Kentucky.

Dr. Clemens describes the species as having the cilia? pale grayish.
