Excerpt from Memoirs on the Coleoptera, Vol. 8: 1918In almost every considerable collection of the Insecta, there are usually many unworked sections consisting principally of uniden tified material. This is especially true of those accumulated by students not having with them assistants to perform the more mechanical work relating to mounting and cleaning specimens and restoring such as may deteriorate through unfavorable conditions in the lapse of time. Among the unstudied sections of the writer's collection, none have been more discomforting than those com prising some subfamilies of the Carabidae, and the material at hand, though very extensive, has been thus far only partially identified and so comparatively useless. It was therefore with the idea of bringing some order out of chaos that the revisions of the present volume were drawn up, not however without many misgivings as to the attitude to be assumed by those having different conceptions regarding what should or should not be called species. These dif ferences of view will continue, however, so long as our knowledge remains imperfect.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
