Abstract

After considering the accepted ideas concerning the wax glands of the Coccidae and Aphidae, the paper describes the structure of these glands in Pemphigus tessellata Fitch as an illustration of the unicellular form, (apparently the only form hitherto recognized ), and in Schizoneura cratagi Oestlund, as illustrating a complex gland.
