Abstract

Abstract does not appear. First page follows.

This investigation was undertaken for two reasons: first, to determine the actual status of Aonidiella aurantii (Mask.) and its so-called variety, A. citrina (Coq.); and second, to learn more about the internal anatomy of the Diaspidinae, as certain structural features still seem to be matters of controversy.

Because of their distinct differences in color and mode of attack, aurantii and citrina are respectively recognized as the red scale and yellow scale. In fact, so specific are they in these differences that their identity is hardly ever confused; to workers in the field the names red and yellow scales mean two different insects. From a systematic viewpoint, however, distinction has not been so clear-cut, as no morphological differences could be detected upon which a differentiation could be based, with the result that citrina, instead of being given specific standing, has been classified as a variety of aurantii.

History and Synonymy

By referring to Fernald(8)A Catalogue of the Coccidae of the World, and to subsequent publications on the Coccidae, one finds that Aonidiella aurantii (Mask.) has been described under many different names. As a result, a long list of synonyms has gradually been built up. It is not within the scope of this paper to enter into an extended discussion of these synonyms. The writer will, therefore, limit himself only to those main genera that played the most important roles in the complicated systematic history of the species concerned.
