wanting, unless the rather doubtful differences between Chambers's larva 

 of quercipomonel/a, and Fitch's larva of ])ometellus, as described by 

 them, can be regarded as sufficient to establish it. It will be admitted 

 that Chambers's description cannot possibly be intended to indicate the 

 black-headed larva, which I take to be erroneously associated with Y. 

 contubernateEus by Fitch. It seems to me impossible to separate spe- 

 cifically the oak-feeding from the apple-feeding varieties ; but a careful 

 comparison of their larvae is necessary before a final decision can be 

 arrived at. 



Genus NO Ell It IS. 



74",. Nothris wetosella. 



Trichotaphe tsetoxella, Clem. 1860, T. N. A. p. 121.

Nothris eupatoriella, Cham. B. IT. S. G. S. iv. 1878, p. 158. 



This should stand as Nothris setoseEa, Clem. The form and color- 

 ing of the palpi at once distinguish it from Gel. Irilobella, Zell. Clem- 

 ens's description is not a good one; he omits to notice the discal spot and 

 the darkened apical portion of the fore wings; it was evidently taken 

 from a somewhat worn specimen. I have been to some extent guided 

 to the conclusion that this is Clemens's T. setosella by having seen a 

 specimen so named in the late Mr. C. T. Robinson's collection at New 

 York. I do not remember to have seen Clemens's type at Philadelphia, 

 but Mr. Robinson was probably acquainted with the species described 

 by him. 



Genus H KL.ICE. 

 727. Helice pnllirioclirclla. Cham. Can. Ent. v. p. 188. 

 Helice ( Getcrhia) pallidorhrella, Cham. " Index." 

 Gelechi.a tjleditxrhkeella, Cham., see " Index." 



This is evidently the species described by Mr. Chambers under the 

 above name, but some mistake has undoubtedly been made in the origi- 

 nal generic description. Mr. Chambers writes of his genus Helice (Can. 

 Ent. v. p. 188), "Secondaries narrower than the primaries; apex long 

 and sharply pointed, with the posterior margin suddenly and deeply 

 incised beneath it and the anal angle rounded." In Can. Ent, vii. p. 

 106, Mr. Chambers states that "Sivoe, Helice, and Agnippe resemble 

 Laverna in having raised tufts of scales on their wings."' The speci- 

 men before me (Mr. Chambers's own specimen from Miss Murtfeldt's 

 collection i lias the bind wings narrow and evenly attenuated from near 

 the base, not incised below the apex, and it lias no signs of any raised 

 tufts of scales on the fore wings. Mr. Chambers probably placed it in 

 the genus Gelechia, under the name of Gelechia gleditschiaeetta (Index,
