Notes on North American Species of Nepticula. 95 



Clemens named this species from mine and larva only ; 

 later it was described under the name dallasiana by Frey and 

 Boll from imagoes bred on blackberry in Texas. The species 

 also occurs at Cincinnati, and agrees exactly with Frey and 

 Boll's description of K . dallasiana. The mine is found most 

 commonly on blackberry, but also occasionally on black rasp- 

 berry (Rubiis occidentalis L.) ; it is a long, very narrow ser- 

 pentine tract. There is great variation in size among the 

 .imagoes ; one captured specimen in my collection expands 

 7 mm. ; the other extreme is represented by a specimen from 

 raspberry, measuring 3 mm. in expanse. 



Nepticula obscurella, n. sp. 



Palpi grayish, paler at their tips. Tuft ocherous. Antenna 

 brownish, eye-caps whitish. Thorax brown. 



Fore wings shining seal brown, tinged with red toward the 

 apex. At the apical fourth of the wing there is an indistinct 

 narrow whitish fascia, broadest in the middle of the wing and 

 fading out toward the ends. When viewed at some angles 

 this fascia is scarcely visible. Cilia of the general hue, their 

 tips paler and concolorous with the fascia. Hind wings gray- 

 ish brown. 



Legs gray, tibia? and tarsi pale. Abdomen brown. 



Expanse : 3.5 mm. 



Described from one specimen, bred from a rather short 

 serpentine mine on Myrica sp. from Montclair, N. J. The 

 cocoon is ocherous, flattened, with a projecting ridge at the 

 anterior end. The leaf of Myrica containing the Ncpticida 

 mine was received with other mines from Mr. W. D. Kearfott 

 in October, 1907. The imago appeared the following spring. 



This species differs from Nepticida myricafoliella Busck, 

 bred on Myrica cerifera in Florida, in the color of the wings 

 and in the position and shape of the pale fascia. 



Type in my collection.
