Classification of the Geometrina of North America (Classic Reprint)

Excerpt from Classification of the Geometrina of North America: With Descriptions of New Genera and SpeciesI have also given more importance to some details of structure than is given by Mr. Meyrick. As an example, my own experience leads me to regard the pencil found on the hind tibiae of the males of many species as a thoroughly reliable point of structure. It may often be rubbed off, and the groove in which it rests be difficult to discern, but the structure is not variable in the same species.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
