Produktbeschreibung
Excerpt from Catalogue of the Described Diptera of North America The aim of this work requires no explanation. A complete inventory of a branch of entomological science, at a given moment of its existence, is the best means for promoting its advancement. Nor does the imperfection of a publication of this kind require an apology; any fair-minded reader is aware that the chief merit to be expected is completeness, and that whenever this is fairly attained, the usefulness of the work will far surpass its shortcomings. It rein tins for me therefore, only to explain the rules that I have followed in preparing this Catalogue. Relation Of The Present Catalogue To That Of 1858. The first Catalogue of North American Diptera, published by me twenty years ago, was, and was meant to be, merely a compilation of the existing literature on the subject. It brought together a mass of references to the descriptions of about 1800 species, scattered in more than one hundred different works and scientific papers. Although such a publication was an indispensable preliminary step before any study of the North American diptera could be attempted, it conveyed but a very vague idea of the actual composition of the North American fauna of diptera. It was impossible to ascertain, at that time, how many of the specific names, enumerated in the Catalogue, actually represented different species, and how many were mere synonyms; neither was it possible to know, whether the species were placed in the right genera, and even in the right families.
