Produced by Jon Richfield EXPLANATION OF TERMS USED IN ENTOMOLOGY PREPARED BY JOHN B. SMITH, Sc.D. Professor of Entomology in Rutgers College, &c. PUBLISHED BY THE BROOKLYN ENTOMOLOGICAL SOCIETY BROOKLYN, N. Y. 1906 PRESS OF THE NEW ERA PRINTING COMPANY LANCASTER, PA. {Scanner's note: This book is about a century old at the time of scanning. I found it in the discard pile of a local university library. I find the book to be of exceptional historical interest in the insights it gives into the development of early modern entomological science. It also is of practical value as a source for terms that are obscure to modern users because they are no longer current. I have edited the text as well as I could and I think it is by now very usable, but do treat any really suspicious looking passages with reserve. I have avoided the use of non-alphabetic symbols as far as I could, for example Greek letters and male, female and hermaphroditic symbols, but if you encounter difficulties you might find the problem there. Also, the colour table at the end is not really much good for anything beyond general impressions; not only are the paper and ink old, but between my scanner and your screen or printer, there is room for too much misinterpretation of precise colour, for anyone to take it seriously. In any case, enjoy. The book is a valuable product of serious workers in an age of exploration.} FOREWORD. When, some time since, in consequence of continuing demands, the Brooklyn Entomological Society resolved to publish a new edition of its Explanation of Terms used in Entomology, and entrusted the writer and two associates with the task of preparing the same, it was believed that a little revision of definitions, the dropping of a few obsolete terms and the addition of a few lately proposed, would be all that was necessary. It was to be a light task to fill idle time in summer, report to be made in fall. Two years have passed since that time; the associates have dropped by the way; the manuscript contains five times the number of terms in the original "Explanation." and if it is published now, it is not because I believe it to be complete; but because I do not believe it can be made complete except as the result of criticism and voluntary addition by specialists throughout the country.
