Abstract

This paper describes the terminalia of two abnormal males of the genus Sarcophaga Meigen (Sarcophaga similis Meade and S. hirtipes Wiedemann var. orchidea Böttcher) which appear to throw light on the interrelationships of the inverted, curvilinear and circumverted types of terminalia in Diptera. The specimens resemble certain stages described by Crampton (1944) in his comparative study of the morphology of the terminalia, and may perhaps represent stages in the pupal development of normal calypterate cyclorrhaphous Diptera.From a study of the pregenital plate in these forms it seems probable that, in Sarcophaga at least, it represents two fused sclerites—probably sternites 7 and 8.
