The fleas of eastern half of the United States east of the one-hundredth meridian, with the exclusion of Texas, are here described and classified: fifty-five species, falling into five families and thirty-three genera, known to parasitize seventy-five mammalian and avian hosts, including man and domestic animals. Data were largely derived from the types in the United States National Museum, in the author's research there, and at Iowa State College.
A brief introduction outlines the collection, preservation, methods of study, life history and control of fleas. The balance of the book contains keys, descriptions, bibliography, synonymic index, host index, general index and an extensive series of plates to facilitate easy and accurate identification.
This is the first separate publication dealing with American fleas since Baker's “A Revision of American Siphonaptera or Fleas” (Proc. of U. S. Nat. Museum, 27:365–469, 1904) and consolidates the new species and new characters since then described in various technical journals.
