Excerpt from Revision of the Aphelininæ of North America: A Subfamily of Hymenopterous Parasites of the Family ChalcididæWhile the work of the Division Of Entomology is entirely carried on with the practical end in view, a certain amount Of work of a technical character IS constantly being done by different members of the force. The condition of our knowledge of North American insects at the present time is such that many forms which from time to time spring Into prominence as destructive species, or as connected with destruc t0 species, either as parasites or predatory enemies, are found to be new to science. They must be classified, described, and given names before they can be intelligently considered in economic publications. The practice which has prevailed to a limited extent of naming and describing new Species in practical bulletins and reports is one which has met with much disfavor among systematic workers. Isolated descriptions of new Species are in themselves sources of great annoy ance to all workers, and when these isolated descriptions are published elsewhere than in scientific journals or the proceedings of scientific societies the annoyance becomes intensified. The force of the Division of Entomology comprises several specialists who are doing descriptive work, and largely upon material accumulated in the course Of the reg ular divisional work. They are doing this work as a necessary supple ment to the purely economic output Of the Division, and to facilitate the investigations of the entomologists Of the State Agricultural Experiment Stations. It becomes important that the results of their labors should be published promptly, and as all available sources Of publication in this country, such as the Proceedings of the United States National Museum and the Transactions of the American Ento mological society, are chronically overcrowded with manuscripts, and are not published with any degree of promptitude, it is necessary that they should be issued by this Department.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
