430 Lord Walsingham on 



show it to be the well-known European Coleophora ccespi- 

 titiella, Zell. Whether it is or is not the species de- 

 scribed by Mr. Chambers I am unable to determine 

 without access to his typical specimens. 



I am indebted to Professor Kiley for calling my atten- 

 tion to a paper by Dr. W. S. Barnard in the Proc. Am. 

 Ass. Adv. Sci., 1879, p. 472, in which it is suggested 

 that one of two probably distinct species of Coleophora 

 feeding on Juncus will be found to be C. cwspititiella. I 

 have not yet been able to refer to this paper. 



A second species in Professor Riley's box was evidently 

 so closely allied to ColeopJiora enrrucipennella, Zell. (Wocke, 

 Cat., 2426) that I wrote to ask for some description of 

 the larval case from which it was bred. This is' now 

 before me, and is, I think, in itself sufficient evidence of 

 the identity of the North American and European forms. 

 This black pistol-formed case, with loose lateral wings or 

 flaps about its widest part, was found on oak, the natural 

 food-plant of C. currucipennella. 



The third species, which appeared to be very closely 

 allied to C. annidatella, Tgstr. (Wocke, Cat., 2546) forms 

 its case, as I am informed by Professor Rile}^, of bits of 

 a species of Polygonmn, upon which it feeds. It covers 

 the case, like its European ally, with grains of sand, and 

 with these are what appear to be some black seeds of the 

 food-plant. The case is rougher, and lies more flatly on 

 the surface of the leaf than that of C. annidatella, 

 having the mouth bent under, the opening being placed 

 nearly at a right angle. I am not aware that the 

 European species has ever been found upon Polygonum, 

 its natural food-plants being species of Atriplex and 

 Chenopodium. 



A fourth example, reared from a larva feeding on 

 Prufius americana, appears to answer to the description 

 of Coleophora rufolutecUa, Cham. (Can. Ent., vi., 129), a 

 species which Mr. Chambers subsequently (Can. Ent., 

 X., 112, 113) regarded as equivalent to C. earycefoUella, 

 Clem., described (Proc. Ent. Soc. Phil., i., 78) as feeding 

 on hickory, and perhaps on dogwood, in a " small dark 

 brownish case of the form of a flattened simple cylinder," 

 which not inaptly applies to the case now received from 

 Professor Piiley. 



The food-plant of the species now under consideration 

 is, however, so completely distinct from that of Dr. 

 Clemens' species that it is most unUkely that the insect 

 can be the same.
