J. Reinhard Texas Agrictiltural Experiment Station, College Station, Tex. In the preparation of this paper I have studied the material in the United States National Museum and the Kansas University Museum, besides my own collection mainly from Texas, and a few specimens from Washington and California. I am under obligations to the late Dr. J. M. Aldrich for the privilege of examining the National Museum material, which includes the types of most previ-ously described forms, and also for his cooperation in supplying references and notes on types not seen by me. To Dr. R. H. Beamer I am indebted for the opportunity of studying the material in the Kansas University Museum collection, which contained several unde-scribed forms from Western and Southwestern United States. My thanks are due also to J. Wilcox and Charles H. Martin, who gen-erously lent specimens for study from their private collections of west-coast flies. Sixteen species are characterized in this revision ; of this number, 10 are new to science. The types of the new species are deposited in the United States National Museum and the Kansas University Museum. Genus CUPHOCERA Macquart Cvphocera Macquart, Ann. Soc. Ent. France, 1845, p. 267.
