habit among the American species that I have observed, a large 

 proportion of the larvae spin cocoons within the mines, gen- 

 erally in the center of the blotch. This is especially true of 

 the generation which passes the winter in the cocoon. 



Three captured specimens in my collection are identical 

 with the two bred specimens, but are a little larger, measuring 

 5 mm. in expanse. The most distinctive features of this 

 species and those which easily distinguish it, are the entire 

 absence of luster, the irregular creamy white fascia formed 

 from scales lacking the dark tips present on the remainder of 

 the wing, and the creamy white cilia. This species is most 

 closely allied to that form of N. platanella Clem, in which 

 there is a complete fascia, but differs from it in the paler 

 bases of the scales of the wing and in the conspicuously creamy 

 white cilia. 



Types in my collection. 



Nepticula leucostigma, n. sp. 



Palpi very i)ale gray tinged with ocherous. Tuft reddish 

 ocherous, collar creamy white. Antennae dark brown, faintly 

 annulate with a paler shade ; eye-caps yellowish white. 

 Thorax dark purplish brown. 



Fore wings dark brown, with a faint purple luster. Be- 

 yond the middle of the wing there is a narrow, faintly shining 

 white fascia, convex outwardly and placed somewhat obliquely 

 on the wing, reaching the margin farther from the base on 

 the dorsum. The scales at the extreme tip of the wing are 

 white, forming, with the whitish apical cilia, a very distinct 

 pale patch. The cilia, except at the apex as just described, 

 are gray. Hind wings and cilia dark gray. 



Legs shining grayish ocherous, hind femur creamy white, 

 hind tarsi dark gray. Abdomen dark purplish above, pale 

 beneath. 



Expanse : -1 mm.
