the eye-caps are too large to permit saginella to remain 

 amongst the Nepticula. The larvae of Trifurcula are en- 

 tirely unknown, so that one can receive no assistance in 

 classification from a knowledge of their habits. 



Bucculatrix, Zeller.

C(X fit* Bucculatrix trifasciella. Fore-wings ochreous, with three 

 silvery, equidistant costal streaks, the first near the base, the 

 last at the beginning of the apical cilia, with the spaces 

 between them somewhat darker than the general hue. On 

 the middle of the dorsal margin is a spot of blackish-brown, 

 with a patch of dispersed scales of the same hue exterior to 

 it, limited externally by a silvery dorsal streak. At the ex- 

 treme tip is a small blackish-brown spot, with an intercilial 

 line of the same hue exterior to it. Cilia ochreous. Hind- 

 wings fuscous ; cilia the same. 



Antennae fuscous. Head ochreous; eye-caps somewhat 

 silvery-white. 



The cocoonet of this species was found on the leaf of a 

 chestnut tree early in July. The cocoon is elongated, ribbed 

 externally, and dark gray. The imago appeared in the latter 

 part of July. 



The leaves of chestnut are mined early in the season by a 

 larva that I have regarded as a Nepticula from the characters 

 of the mine, but I am now disposed to think that the mine is 

 made by the larva of trifasciella during its early life. This 

 mine is noticed in the Proceedings for November, 1861, p. 85, 

 under Nepticula saginella.\
