The new Catalogue of the Lepidoptera of North America which I have prepared has been issued as Bulletin No.52 of the United States National Museum. It comprises 740 pages. The edition is being distributed by the Smithsonian Institution, without charge. Those not receiving the publications of the National Museum regularly, and who are interested enough in entomology so that this publication would be of practical use to them, will be cheerfully recommended by me to receive a copy, on making application to the undersigned.
