Biological Papers. 155 SOME RESULTS OF THE UNIVERSITY OF KANSAS ENTOMOLOGICAL EXPEDITIONS TO ARIZONA in 1904 and 1905. By F. H. Snow, University of Kansas, Lawrence. ■^r^HE expedition of 1904 made its headquarters at Thomas's -^ ranch, in Oak Creek canyon, twenty miles southwest of Flag-staff, in Coconino county, 6000 feet above sea-level, the locality visited in 1902. My associates were Prof. W. H. Johnson and two students, Messrs. Eugene Smyth and Judah Drisko. Our collect-ing continued for seven weeks, from July 16 to September 2. The expedition of 1905 made camp on the San Bernardino ranch, in the valley of Sycamore creek, between the Perilla mountains and the Peloncillo mountains, eighteen miles east of Douglas, in Co-chise county, in the southeast corner of Arizona, and close to the United States and Mexico boundary line. This ranch is an oasis in the desert, and its proprietor, Mr. J. H. Slaughter, and his esti-mable wife and family rendered us many valuable services. Our tents were pitched in close proximity to a flowing artesian well, about three quarters of a mile from the ranch houses and within a quarter of a mile of the spot where the Apache chieftain, Ge-ronimo, gave up his arms. The altitude of our camp was about 3750 feet above sea-level. My assistants on this trip were three students, Messrs. Eugene Smyth, Ebb Crumb, and Rollin Perkins, and I have never had a more indefatigable corps of collectors. Our collecting period included five weeks, from July 30 to September 2, making a total of twelve weeks of field-work for the species enumerated in these lists. I. -LIST OF LEPIDOPTERA. For invaluable aid in the determination of species not readily determined from the University of Kansas collection, the author is indebted to Dr. Henry Skinner and Prof. John B. Smith. The numbers and nomenclature are those of Smith's check-list of 1903. Abbreviations: S. for San Bernardino ranch; O. for Oak Creek canyon. Family Nymphalid^. 1 Danais plexippus Linn.
