REVISION OF THE AMERICAN TWO-WINGED FLIES 

 BELONGING TO THE GENUS CUPHOCERA 



By H. 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.
