not aware that there is any part of the state in which it does not 

 occur. 



Rhode Island. — Mr. C. W. Johnson has specimens from Kingston, 

 R. I., and the species is evidently equally abundant in Rhode Island 

 as in the adjoining states. 



South Carolina. — Bishopp ^ states that the stable fly occurs com- 

 monly in South Carolina and sometimes becomes a considerable pest 

 of live stock. 



South Dakota. — According to Bishopp ^ statements by farmers in 

 South Dakota indicate that the stable fly is sufficiently abundant 

 there to become a live-stock pest. 



Prof. J. M. Aldrich writes that he has specimens in his collection 

 from Brookings and Custer, S. D., and that he has observed it as 

 troublesome to horses in South Dakota. 



Texas. — Very recently Bishopp ^ has referred to the great abundance 

 of the stable fly in northern Texas during the summer of 1912 and to 

 its prevalence in the same region every year.. In the south central 

 portion of the state, the present writer found the species always rather 

 commonly, but not in excessive outbreaks during several years of 

 residence there. It is undoubtedly very widelj^ distributed in Texas 

 and an extremely important pest of live stock in most if not all parts 

 of the state. 



Bishopp (1. c.) also says that this species was reported as extremely 

 abundant in north central Texas as early as 1867, and that later out- 

 breaks occurred in 1894 or 1895 and in 1905. 



Pratt ^ records the species as very abundant in and about stables 

 at Dallas, Tex., but as not breeding commonh in cow-manure ac- 

 cording to his observations. 



Virginia. — Howard * has found this species commonly in northern 

 Virginia, and mentions its occurrence in out-of-door privies in this 

 region. 



West Virginia. — Howard ^ refers to the occurrence of adult stable 

 flies in out-of-door privies at Charleston, W. Va. 



Wisconsin. — Carlyle ^ records Sto?noxijs calcitrans as being very 

 common and as constantly worrying stock, particularly cattle in the 

 "Northwest." The writer has observed it in numbers in southeasterly
