Mr. Chambers first described this species under the new generic name 

 jEsyle, and drew attention to its great similarity to Lithocolletis, except 

 in the neuration of the hind wings (Cin. Quart. Journ Sci. ii. p. 98) ; 

 subsequently (Can. Ent. ix. p. 194) he suggested that this species. 

 which he found had also been described by him under the name " Gra- 

 cilaria Q-iiotellu" might possibly be the Gracilaria fulgidella of Clem- 

 ens. 



I think this is not improbable, having regard to Dr. Clemens's descrip- 

 tion of G. fuhjidella, and to my brief note on Clemens's type made in 

 1872: — "Surely not a Gracilaria ? a small species." The species de- 

 scribed by Mr. Chambers has not the antennae of a Gracilaria, these 

 being shorter than the anterior wings in the specimen before me. It 

 was probably this same character which led me to doubt Clemens's speci- 

 men being a true Gracilaria, except in the form of the palpi. It ap- 

 pears to me to be more nearly allied to Lithocolletis than to Gracilaria, 

 but [ have not examined the neuration. Mr. Chambers's figure of the 

 hind wings (Journ. Cin. Soc. Nat. Hist, p. 203. fig. !>4 ) certainly shows 

 some slight divergence from those of that genus, [n the collection of 

 the Peabody Academy of Sciences, Salem. Mass., are specimens of the 

 two extreme varieties referred toby Mr. Chambers (Can. Ent. ix. p. 

 194, xi. p. 118). It is difficult to believe that they can be referable to 

 the same species, although he gives apparently good reasons for thinking 

 that they are so.

Lithocolletis trifasciella, Cham. Can. Ent. xi. p. 92. 



This species approaches very closely to Lithocollei 'is fralichiclla , Zell. 

 (Wocke, 2892), but differs from it in having the first and second trans- 

 verse fasciae curved outwards, instead of straight as in the European 

 species. L. mariseella. has been bred from Sgmpkoricarpus ', L. froz- 

 lichiella feeds on Aluus. I received a specimen in 1878 from Miss 

 Murtfeldt, labelled U L. bicidicostella, Clem. ; mariseella. Cham." It is 

 quite distinct from lucid icostella, of which Mr. Stainton writes (Tin.
