Produktbeschreibung

Excerpt from Bulletin of the United States National Museum, Vol. 31 That which has been aimed at in the present Synopsis is the description, as full and complete as possible, of the North American Syrphidae. The labor involved in the determination of our diptera, save such as have been described or monographed by Dr. Loew and Baron Osten Sacken, is very great, owing to the often incomplete and unsatisfactory descriptions scattered through the literature of a half dozen languages. To bring together descriptions in such a way as will render the identification of our numerous species less toilsome and more certain, is the only means that will now materially further the study of American diptera; the description of desultory new species is detrimental to real progress in the knowledge of our fauna. My aim has been the study of genera and species, to so describe and figure those of the United States as to render them more easily determinable. With every page I write I feel more fully how difficult descriptive dipterology really is, and that only a beginning has been made in the study of this interesting family. But the work will, I trust, serve a useful purpose in pointing out what the needs and necessities are, and to pave the way for a future exhaustive monograph of the family, based upon a wider knowledge than is now possible. I have given especial attention to this family since the beginning of my dipterological studies eight years ago, and have collected a large part of the species, either in New England or the West. I could not, however, have accomplished what I have, except by the aid of the many friends who have kindly sent me material. Without in any way depreciating the favors of others, I would express my acknowledgments especially to Prof. J. H. Comstock, of Cornell University, for the aid furnished me in the examination of a considerable collection, among which I found the very interesting genus Senogaster; to Mr. Eugene L.Keen, of Philadelphia, who, in the most generous way, gave me freely everything I desired from bis industrious collecting; to Prof. C. V. Riley, of Washington, for the privilege of examining his large collections, including the excellent one of Mr. E. Burgess; and to Mr. D. W. Coquillett, of Anaheim, Cal., Mr. Theodore Pergande, of Washington, D.C., and Dr. George Dimmock, of Cambridge, for the addition of not a few species otherwise unknown to me.
