During the winter of 1900–1901 the larvæ of this pretty Grapholithid were rather abundant at Ottawa, hibernating in the heads of. mdlein (Verbascum thapsus). Full-grown specimens were collected by the writer and Mr. C. H. Young in April, which pupated in the office on and about the 25th April, the first moths appearing on the 11th May, and the last specimen emerging on the 22nd May.

These larvæ were found in the seed-pods, and had been feeding onthe seeds; numbers were present in the same head, As far as the writer knows, this is the first record, at least in Canada, of the caterpillars feeding on mnllein. Dr. Horvard writes that Mr. Coquillett has reared the species from Stachys palustris, and Mr. Coquillett from a species of flag. He adds: “It evidently has several food-plants, and sometimes it does injury to plants after they have been pressed for the herbarium.”
