 BELONGING TO THE GENUS WINTHEMIA

Parasitic flies of the genus Wintheniia are perhaps more often 

 reared in economic work than any other species of Tachinidae. Co- 

 quillett in 1897 ^ recognized four species from America north of 

 Mexico, and hitherto no comprehensive work on the genus has been 

 published. The present paper contains descriptions of 32 species, of 

 which 16 are new to science. In the preparation of this paper I have 

 studied the material contained in the United States National Museum, 

 which includes the types or specimens compared with types of practi- 

 cally all the previously described American forms. 



I am greatly indebted to Dr. J. M. Aldrich, associate curator of the 

 division of insects, for placing the facilities of the United States 

 National Museum at my disposal, and for numerous other favors, 

 particularly for the use of his notes on the types of several American 

 species in European museums, which have proved invaluable in 

 clearing up uncertainties that otherwise could not have been eluci- 

 dated. Acknowledgment is gratefully made also to A. B. Conner, 

 director of the Texas Agricultural Experiment Station, and to the 

 United States Bureau of Entomology for providing an opportunity 

 to conduct this study, and to Charles T. Greene for preparing the 

 drawings herein included. I am under obligation to C. Howard 

 Curran for the privilege of examining the material contained in the 

 American Museum of Natural History, including two undescribed 

 forms for which credit is given under each species. My thanks are 

 due the late Prof. James S. Hine and also to Dr. Charles Robertson, 

 Dr. T. H. Frison, Colbran J. Wainwright, and Ray T. Webber, who 

 generously loaned material for study. Determined specimens of 

 Wintheinia qwadripustulata received from the eminent European 

 authorit}^, Dr. J. Villeneuve, have been very useful in making deter- 

 minations of our American forms.
