Abstract
A RECENT cytological investigation by me of chromosome individuality in three arrhenotokously parthenogenetic species of Hymenoptera Symphyta has yielded evidence which indicates that the relationship between the females and males is not one of diploidy: haploidy, but is of tetraploidy: diploidy. This concept leaves considerably less to be explained with regard to the occurrence of parthenogenesis; but the matter of the abortive meiosis in the sperm-atogenesis of impaternate males would seem, at first sight, to be elevated thereby to the rank of a first-rate problem. Resolution of this, however, is still possible along cytogenetic lines on the basis of a principle of gene-controlled meiosis.
