Abstract

The purpose of the present paper is to discuss the variation in, and systematics of, this species. We have been able to study 601 specimens of D. parvifrons. In addition to specimens in the Albert Schwartz Field Series (ASFS) we have borrowed pertinent material in the Museum of Comparative Zoology (MCZ), United Sta tes National Museum (USNM), American Museum of Natural History (AMNH), Museum of Zoology, University of Michigan (UMMZ), Carnegie Museum (CM), and the Senkenberg Museum (SMF).
