DIPTEROLOGICAL CONTRIBUTIONS. 



BY C. F. ADAMS. 



TT^OR the pleasure of studying diptera in the University of Kansas, 

 -*- I have to thank Dr. F. H. Snow, whose interest in things scien- 

 tific is so well known. To Dr. S. W. Williston I am under deep ob- 

 ligations, for the use of his dipterological library and his collection. 

 To Prof. J. M. Aldrich and Mr. D. W. Croquillet thanks are due for 

 looking up references. 



The material reported in this paper comes principally from two lo- 

 calities, Rhodesia, Africa, and western North America. The Afri- 

 can material was collected by Mr. F. L. Snow, son of Dr. F. H. Snow, 

 while visiting near Salisbury, Rhodesia. This lot is a very important 

 addition to the University collection, and as I get time and literature 

 more at my command I shall report further concerning it. Most of 

 the American species were collected by exjjeditions under the direc- 

 tion of Doctor Snow. I have Doctor Williston's consent for includ- 

 ing his two new species in this paper.
