Mr. Chambers adds to the list of plants, on which he has found 

 Tischeria malSfoliella feeding, the dewberry, Ruhus canadensis, found 

 since the publication of the July number, and further says : 



When my former paper was written, 1 was led, from the fact that 

 Prof. Frey gives Pareciopa robiniella, Clem., as a synonym of his 

 LithocoUetis gemmea, and from the best understanding that I could 

 then get from his description, to believe that he had specimens of P. 

 robiniella before him, and that he was simply redescribing P. robiniella, 

 Clem., as L. gemmea, Frey, and I was fortified in this conclusion by 

 the fact that under his description of L. gemmea he remarks, that "the 

 mines of Robinia pseud accacia" (Black Locust), "consist of a common 

 LithocoUetis dwelling, with a smooth edge, in which the caterpillar is 

 transformed." (This is certainly the mine of LithocoUetis robiniella, 

 Clem.); " or, again, in a digitated mine of the upper side " (which is 

 evidently the mine of Parectopa robiniella, Clem.); " or, thirdly, in an 

 upper and under side mine of rounded not much serrated shape," (which 

 is very clearly the mine of LithocoUetis ornatella, Chamb.) All these 

 mines, and the larvae which inhabit them, and the insects bred from 

 them have been thoroughly known to me for years. L. robiniella and 

 P. robiniella were thoroughly known to Dr. Clemens, and so was L. 

 robiniella, and the mine and larva of L. ornatella to Dr. Fitch. These 

 mines and insects are found all over the United States, where the 

 locust tree is found, and no other mines except those of the butte 

 Hispa siduralis, have ever yet been found in locust leaves, though they 

 have been made the objects of careful investigation from New York 

 and Minnesota to New Orleans. 



It is evident, however, from a closer study of Prof. Frey's paper, that 

 his identification of P. robiniella, with L. gemmea, as described by him, 

 is very wide of the mark. P. robiniella, Clem., can not possibly he iden- 

 tified with either of the forms described by Prof. Frey, under L. 

 gemmea. These forms appear to me to be much nearer to ornatella, than 

 to Parectopa robiniella, or to LithocoUetis robiniella. Indeed, a specimen 

 of L. ornatella, with the second fascia interrupted in the middle, might 

 pass for L. gemmea, but for the white-tipped antennae and spot at the 

 apex of the wings, which Prof. Frey gives to his L. gemmea. I 

 do not think, however, that it can be a variety of ornatella. Prof. Frey 

 evidently had the " digitated mine " of Parectopa robiniella, Clem., 

 before him, but just as evidently he did not breed that species from 

 them ; at all events he has not described it in his brochure, nor anything
