104 Tineina of the Central United States. 



the confluence of the costal and dorsal streaks, and is angulated. I have 

 met with a specimen (bred) which I believe to belong to this species, 

 but in which the dusting was almost entirely absent, possibly it may 

 be a distinct species. 



L. ^riferella, Clem. 



I have bred this species from the leaves of the black jack (Qiier- 

 cus nigra), and have found it so often in groves of Avhite oak (Q. alba) 

 and black oak (Q. tinctoria), where there were no black jacks near, 

 that I think it must mine the leaves of those species also. 



L. Castaneceella (n. sp.) 



Face and palpi silvery white ; tuft, thorax and anterior Avings reddish 

 golden (or pale reddish orange?); antennas dark brown, with a faint, 

 narrow, whitish annulation at the base of each joint, toward the apex; 

 each alternarte joint is white, as is also the case in L. bethunella and L. 

 unifasciella. There is a small white spot on the costal margin of the 

 anterior wings, about the basal fourth, and therein it differs from miifas- 

 eiella and a silvery ftiscia just beyond the middle (as in umfasciella, but 

 not dark margined on the costa before, as in that species). The wing 

 behind the ftiscia is dusted along the middle, the dusting extending 

 over the entire apex. A small, white costal streak at the beginning of 

 the costal ciliae, and another small one just before the apex, both in 

 the dusted portion as in bethunella. A dark brown hinder mar- 

 ginal line, formed by the dusting, at the base of the cllise. Al. ex., 

 one fourth inch, Kentucky. 



The larva is flat, and mines the upper surface of leaves of the chestnut, 

 {Castanea Americana), and of a species of oak. (The leaf was too much in- 

 jured to determine the species of oak). When it was gathered from 

 oak, the mine was supposed to be that of L. haviadryadeUa, and the 

 larva was not closely observed, and it was placed in a large breeding 

 cage with several other well known species, for the purpose of getting 

 duplicates. Subse(|uently, on looking over them, I was surprised to find 

 that this Avas an unknown ribbon like mine : not corrugated along the 

 center, and with the pupa lying naked on a few threads of silk. It was 

 then separated from the other mines, and produced this species. The 

 imago is between bethiinella and imifascieUa, having some, but not all 

 of the streaks of bethunella, which are wanting in unifasciella. The 

 fascia resembles that of unifasciella more than that of bethunella. The
