In Vol. XXXII. and XXXIII. of the list of Lepidoptera Heterocera in the British Museum, Mr. Walker described some species from “West Canada, in the Rev. Mr. Bethune's collection.” No records of specimens in the Museum are given, and the descriptions are of specimens apparently returned to the collector. On the chance of these specimens being still in existence I wrote Dr. Bethune, begging him for such assistance and information as was in his power to afford. He very kindly responded, saying, “I shall send you by mail to-morrow a box containing the few specimens that I have left that were named for me by the late F. Walker.
