oa Journal of the Entomological Society of Southern Africa - The comparative value of some structural characters of Rhopalocera (Lepidoptera) in specific diagnoses



The diagnostic characters used for the purposes of classification in the eighteenth and early nineteenth century, as far as Lepidoptera are concerned, were mainly differences or similarities of appearance which were obvious to the casual observer, and among these, the peculiarities of colour and pattern of the wings received particular attention. It is obvious that a classification based on such superficial grounds was to a great extent illusionary, often bringing together, under the same genus, not only rather distantly related members of the same family, but also representatives of vastly different families and even of distinct suborders.
