Males and Intersexes in a Normally Thelyotokous Insect, Tropidophryne melvillei Compere (Hymenoptera, Encyrtidae)

Abstract
Tropidophryne melvillei Compere is apparently indigenous to the region of Kenya Colony, Africa, where it was found to parasitize Pseudococcus sp. (Compere, 1939). In 1948 this parasite was introduced into California from Kenya Colony by the Division of Biological Control of the University of California Agricultural Experiment Station (Smith and Flanders, 1949).
