Hardback, [PU: Forgotten Books], Excerpt from The Genitalia of the Group Tortricidæ of the Lepidoptera of the British Islands: An Account of the Morphology of the Male Clasping Organs and the Corresponding Organs of the Female In the previous volumes the genitalia were drawn to scale, a fact which had in some respects a certain advantage; but it had also the disadvantage of reducing the figures of the smaller species so greatly as to destroy, their value. After carefully weighing the pros and cons, we decided to keep the drawings fairly uniform in size, in order that the different and characteristic points, in even the smallest species, might be shown. I have found the Tortrix men so generous in helping with specimens, many in cases of difficulty sending their entire series to do as I liked with, that I have added the names of the donors to the species, so kindly provided by them, and I wish this to be a record of my grateful thanks. The ever difficult question of the Nomenclature has been considered, although from the point of view of my particular study, the question of names is really a matter of no great importance. The generic names have been worked out with the aid of Mr. O. H Fernald's The Genera of the Tortricidae and their types. Where we have been unable to find any existing generic name, we have left a blank space, and the same with regard to the type. So many genera have been created for foreign species, that, until these have been examined from a genitalic point of view, we have been averse to providing superfluous names for genera which may already exist. These blanks may be filled in as our knowledge increases. For the specific names I have relied mainly on the type collection in the Victoria Museum at Manchester, named by Mr. J. H. Durrant, and to him I am indebted for much help in this, and other matters. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
