Book excerpt: Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This book was released on 2015-08-04 with total page 228 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: The dipteran family Chironomidae is the most widely distributed and frequently the most abundant group of insects in freshwater, with rep resentatives in both terrestrial and marine environments. A very wide range of gradients of temperature, pH, oxygen concentration, salinity, current velocity, depth, productivity, altitude and latitude have been exploited, by at least some chironomid species, and in grossly polluted environments chironomids may be the only insects present. The ability to exist in such a wide range of conditions has been achieved largely by behavioural and physiological adaptations with relatively slight morphological changes. It has been estimated that the number of species world-wide may be as high as 15000. This high species diversity has been attributed to the antiquity of the family, relatively low vagility leading to isolation, and evolutionary plasticity. In many aquatic ecosystems the number of chironomid species present may account for at least 50% of the total macroinvertebrate species recorded. This species richness, wide distribution and tolerance to adverse conditions has meant that the group is frequently recorded in ecological studies but taxonomic difficulties have in the past prevented non-specialist identification beyond family or subfamily level. Recent works, including genetic studies, have meant that the family is receiving much more attention globally.
