The Golden-rods in the vicinity of Buffalo—especially observed on Squaw Island—harbor the larvæ of two plume moths, one boring the branches, stem and root, the other using the foliage. I have sent the moths to Mr. Charles Fish, of Old Town, Maine, for determination ; he concludes that they are both unnamed, and he will describe and name them in a general paper in preparation on the American species. As a somewhat more detailed account of their habits than a technical paper will allow seems to be desirable, I have prepared these notes, relating mostly to the borer.
