New Species of Tineina. 295 



of the fore-wings is a rather wide, irregular, white fascia, a little nearer 

 to the base on the costal than on the .dorsal margin; before the apex is 

 a dorsal white spot, and opposite, but a very little behind it, is a 

 costal one, which almost joins it in the middle of the apical part of the 

 wing. Extreme apex, white, with a dark brown, hinder marginal line 

 behind the white ; cilia, pale grayish. The basal part of the wing, to 

 the fascia, is paler than the remainder of it; dorsal cilia, fuscus; hind- 

 wings and their cilia, fuscus ; abdomen, purplish brown. Al. ex., 3 lines. 

 Amherst, Goodell. It belongs to the same section with B. prcematur- 

 ella, Cl€m. The Kentucky species which I formerly mistook for prce- 

 matiirella, and which is very near to it, is however a different species 

 from prcematurella, differing from it in the neuration. 



GRACILARIA. 



10. G. ACERIELLA. n. Sp. 



Ver}^ different from G. packardella, Cham, and G. acerifolitlla, 

 Cham., which feed on maple, and more Vik^strigijinitella, Clem., or 

 12-lineella, Cham.; but it is still nearer to G. juglandismgrce'eUa, 

 Cham. Indeed, it seems to differ from this latter species chiefly b}^ being 

 a little smaller, by having the tips of the palpi white, and the disc of the 

 fore-wings more obscurely flecked with white scales, while the dorsal 

 margin and cilia are more distinctly so; and there is a series of small, 

 white, costal spots ; or rather the costal margin from the apical third 

 of its length is white, divided into a series of spots, b}^ about eight fine 

 brown lines, and the cilia are divided b}^ two white lines. As in jug- 

 landis7iigraiella, the ground color is a dark, blood brown. The face 

 and palpi are white; the palpi, flecked or annulate with brown, and; 

 the basal half of the posterior femora is white; abdomen, brown, 

 with the anal tuft and under surface, pale stramineous. A single male, 

 which Mr. Goodell informs me was bred from maple leaves. 



The collection contains also, G.superbifrontella,- Clem., G.packard-^ 

 ella, Cham., G. erigeronella, Cham., G. rhoifoliell'a, Cham. (I find that 

 I have sometimes carelessl}?^ written this G. rhoisell'a), and G.-pidc-hella, • 

 Cham. It contains also an Ornix^ which may be 0. inusitatumella, • 

 Cham. But it is useless to attempt to separate some of the species of 

 Ornix without authentic specimens to compare with, and I have none 

 of this species now.
