Book excerpt: Excerpt from The Families and Genera of North American Diptera It is my hope that those who may discover errors or omissions may be kind enough to call them to my attention, indicating the manner in which the corrections may be made. Owing to the numerous footnotes it has not been possible to indicate the genera which have been included from description only. Such genera naturally weaken a key as it is impossible to use characters which may be available for a more suitable arrangement. Any specimens representing genera improperly placed, or not common, would be most greatly valued by the author.

Book excerpt: Excerpt from Manual of the Families and Genera of North American Diptera Eight years ago the author of the present work published a small volume in which he attempted to tabulate the families and more important genera of the diptera of the United States. From the use that has been made of that work by entomological students, he has been encouraged to believe that the labor of its preparation was not in vain. The extraordinary activity in the investigation of our dipterological fauna within the past few years has, however, largely destroyed its usefulness, and it is hoped that this new edition, or rather this new work, will prove as serviceable as has been the former one. In the present work there has been an attempt to include all the genera now known from north of South America. While the Central and West Indian faunas are preeminently of the South American type, there are doubtless many forms occurring in the southern states that are at present known only from more southern regions. In the preparation of the work the author has been aided by the examination, so far as he was able, of extensive collections from the West Indies and Central America submitted to him for study by Dr. D. Sharp of Cambridge, England, and Messrs. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Synopsis of the Families and Genera of North American Diptera, Exclusive of the Genera of the Nematocera and Muscidae With Bibliography and New Species, 1878-88 Tm; writer has, during the past five years, published in different periodicals various synoptic tables of the families and genera of North American Diptera. The intention was, at first, to reprint these with revisions, that they might be more accessible to those interested in this order of insects. In order to make, it is trusted, the tables of more service, those of other families have been added, either as compiled or reproduced from standard authorities, or pre pared from the examination of specimens in the author's collection. It will be understood, however, that, in not a few families, the pres ent condition of American dipterology does not admit of the prepa ration of synopses free from error; the writer's acquaintance, too, with not a few families, has been less complete than with others, and it is very true that only he who has made a critical study of abundant material is competent to compile such tables with much success. For this reason, the tables of genera in the Nematocerous and Muscid families have been omitted. It may be mentioned that very nearly all the genera defined in the present work have been examined by the writer, though not all with the same degree, of critical study. The faunal limits embraced are those north of Mexico; and whenever extralimital forms are introduced they will be found preceded by a 0.

Book excerpt: Excerpt from Manual of North American Diptera The order of two-winged insects known as flies or Dip tera includes more than forty thousand known species from different regions of the world. Since many of the species are small, or even minute, and inconspicuous, and since the order as a whole has not received the at tention from collectors and students of entomology that other and more attractive groups have, it is very certain that many more await discovery. A very reasonable es timate would place the entire number of species of flies at present in existence at more than eighty thousand. From North America the recent catalogue of Aldrich gives a list of about eight thousand species, distributed in more than a thousand genera. The subject is a wide one and replete with interest.

This book was released on 2016-06-27 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Catalogue of North American Diptera (or Two-Winged Flies) The present work is based upon Osten Sacken's Catalogue of North America Diptera, second edition, published in All the references of that work are embodied in this, with only such changes as later studies seem to require. Still, the great amount of work which has been done on North American Diptera within the quarter of a century has largely changed the face of the subject. Hence the reader will probably observe, especially at first, more of contrast than resemblance. The number of species has doubled; the number of references to previously known species has almost doubled; several families have been monographed or revised, with more or less change of nomenclature; along with this has gone the publication of a multitude of smaller papers, touching every family but one, and the larger part of the genera. Under these conditions it is inevitable that great changes should appear in the new catalogue. It is the more necessary that I should acknowledge my obligation, which is far greater than appears on the surface. Fauna! Limits - These, as in the former catalogue, include all of North America, in the widest sense, taking in Panama on the South and Greenland and the Aleutian Islands on the North. The West Indies are included, even down to Trinidad, adjoining Venezuela. There is no place to draw a line between the islands. The Bermudas and the Hawaiian Islands are not included.
