A List of British Aphides (including Notes on Synonymy, their recorded Distribution and Food Plants in Britain, and a Food-Plant Index)

Abstract

THE volume under notice is the fourth of the recently instituted series of “Rothamsted Monographs on Agricultural Science,” and is the first to treat of an entomological subject. The morphological characters separating allied species of aphides are often com paratively trivial, and this fact, coupled with poly morphism and a certain plasticity of host-selection, has led to much confusion in the identification of these insects. Their involved nomenclature has been badly in need of revision, and in many cases it has become a difficult task for the entomologist,. who was not a"professed aphidologist, to make certain of the genus or species to which a given name is strictly applicable.
