Book excerpt: Excerpt from New or Little-Known Crane-Flies From the United States and Canada; Tipulidae, Diptera, Vol. 2: From the Proceedings of the Academy of Natural Sciences of Philadelphia, September, 1915; Issued November 10, 1915 In the present paper, the author has undertaken a consideration of the American crane-flies contained in the collections of the Boston Society of Natural History and the Museum of Comparative Zoology at Cambridge. These collections are of peculiar interest to the student of crane-flies since they include the numerous types of Johnson, Osten Sacken, and Loew, in addition to a considerable amount of unclassified material. The paper has been divided into two parts, the first being a designation of the single-type specimen of the species of Tipula described by Loew, the second part a continuation of the first paper under this title. I wish to express my deep appreciation to all of the persons who have kindly assisted me in this study, most of whom are designated in various parts of the paper. I am especially indebted to Mr. Charles W. Johnson and to Mr. Samuel Henshaw for the great privilege of examining and studying the invaluable collections in their custody. Part 1. Designation of the Single-type (Lectotypic) Specimen Of the North American Species of Tipula Described By Hermann Loew. The North American crane-flies described by Hermann Loew were included in a series of papers published between the years 1861 and 1872 under the general title of Diptera Americ septentrionalis indigen and appearing in the Berliner Entomologische Zeitschrift. This remarkable series of articles was in ten parts or centuries, each containing the description of a hundred species of flies. The references will be merely to the "Century," with the number of the species in the century and the original pagination.
