Excerpt from May Flies and Midges of New York: Third Report on Aquatic Insects; A Study Conducted at the Entomologic Field Station Ithaca, N. Y. Under the Direction of Ephraim Porter Felt D. Sc This, the third report upon work begun in 1900, like its predecessors, marks an important advance in knowledge. The first report, State Museum Bulletin 47, consisting of 230 pages and 36 plates, gave the life histories of about one hundred aquatic forms and characterized ten species and two new genera. The most important portion of this work was the monographic ac count of the larger dragon ies (0 d o n a t a A n i s o p t e r a) There were also valuable additions to our knowledge of the stone ies (p lecoptera) and the May ies (e phemeridae), and the admirable account of the Caddis ies (t r i c h o p t e r a), by Mr Betten, deserves special mention because of its careful bio logic treatment of a heretofore much neglected group. The second report, State Museum Bulletin 68, comprised 419 pages and 52 plates and was a continuation of the preceding. The monograph of the Odonata is completed by an exhaustive account of the smaller dragon ies (z y g o p t e r a). Among the important contributions mav -'be mentioned: The key to C o 1 e o p t e r o u s larvae with an account of some aquatic C h ry so m e l i d a e by Dr )iacgillivray, the discussion of cer tain aquatic nemato-cerous 'd i p ter a by Dr J ohannsen, and a monograph on the S i a 1 i d i d a e of the Western Hemisphere. The present report is a continuation of the work, and among its valuable features should be noted the monographic account of our May ies, a group of great importance as food for fish. The small midges, belonging to the G h i r o n 0 mi d a e, are very important as fish-food and have been treated exhaustively by Mr Johannsen. These three publications mark a most decided ad vance in our knowledge of aquatic forms and, with the publica tion of the monograph on stone ies now in preparation, a large fund of information will be available for the student of aquatic forms.
