RESULTS OF THE YALE PERUVIAN EXPEDITION OF 1911. LEPIDOPTERA. By Harrison G. Dyar, Custodian of Lepidoptera, United States National Museum. A large part of the species of Lepidoptera could not be found in the collection of the United States National Museum at Washington, and I accordingly enlisted the aid of Mr. William Schaus, who very kindly compared the specimens in London. He submitted certain specimens to various specialists, to all of whom my thanks are cor-dially extended. The collection contains 242 species, here listed. Family PAPILIONID^. PAPILIO P^ON Boisduval. Cotahuasi, 9,000 feet, October 11, 1911. Machupichu, 1912. PAPILIO MADYES MONTEBANUS, new subspecies. Submarginal spots of hind wing above slender, incised, nearly divided, white in the male, yellow in the female, white edge of the wings very broad in the incisures between the veins.
