Explanation of Terms Used in Entomology

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.
