Notes on North American Species of Nepticnla. 85 



The number of species now known only in the larval state is 

 thus reduced to six, juglaiidifoliella Clemens having been later 

 described by Chambers and nyssccfoliella Chambers by the 

 writer. 



Nepticula pallida, n. sp. 



Palpi pale ocherous. Tuft yellowish, the scales on the 

 vertex tipped with orange. Antennae pale ocherous, eye-caps 

 whitish. Thorax very pale tawny. 



Fore wings very pale tawny, with a very faint metallic 

 luster, the scales tipped with pale ash-brown, more deeply so 

 toward the apex of the wing, so that although the wing is 

 mottled, the general color becomes deeper toward the apex. 

 Cilia very pale tawny. Hind wings pale gray, tinged with 

 ocherous. 



Legs and abdomen very pale straw-colored. 



Expanse : 4 mm. 



Described from one specimen bred on a narrow-leaved 

 willow, Sali.v sp., from Cedar Point, O., on the lake shore. 

 The mine occurs on the low^er side of the leaf and is extremely 

 narrow at first, extending along the midrib, later doubling on 



Mine of A', pallida. 



itself once or twice, and gradually and evenly increasing in 

 breadth to its end, where it measures a scant 1.5 mm. across. 

 The entire length of the mine is approximately 4.5 cm. The 

 color is brownish throughout and not at all transparent. The 

 frass is distributed in a broad tract throughout the entire length 

 of the mine. The larva spins an oval reddish brown cocoon, 

 without projecting ridges. 



This species is most closely related to A', populctoriim F. 

 and B. from which it may be distinguished by the paler color, 

 in particular by the paler frontal tuft. The mine is decidedly 

 different in appearance. 



Type in my collection.
