NOTES ON ROBBER FLIES FROM SOUTHWEST 



TEXAS, COLLECTED BY THE BRYANT WALKER 



EXPEDITION, WITH A DESCRIPTION OF 



A NEW SPECIES OF ERAX 



By James S. Hine 



The material considered in this paper consists of some 130 

 specimens collected fortuitously hy Mr. F. M. Gaige on the 

 Bryant Walker Expedition from the ?\Iuseum of Zoology, 

 University of ^lichigan. in the Trans-Pecos region of Texas 

 in 1916. Eighteen species are represented in the collection, 

 which taken as a whole is characterized by the large size of 

 the majority of the specimens. It is seldom that a small col- 

 lection contains so many species of special interest. Mr. 

 Gaige's statement regarding the locality which the expedition 

 visited will give an understanding of the conditions under 

 which the collection was made. 



"The region worked is situated some forty miles south and 

 slightly west of Pecos, the nearest town being Toyahvale.
