Forbes intended this work to primarily to make easier the recognition of the lepidoptera of the State of New York. This work was meant to be a compilation of information available at that time, including notes associated with the various collections and from previous publications, most notably, Holland’s The Moth Book. It also contains considerable information and keys that had not been previously published.

This publication has been a good resource for updating the descriptions on a large number of moth guide pages that were created “on the run.” It can be downloaded as a PDF of images of the original document and/or an editable OCR text file.
