The first capture of E. arbustorum in America, as far as my in- 

 formation goes, dates from June 15, 1906, when a single female was 

 taken by me at Ft. Lee, N. J. In 1908 a number of records appear, 

 specimens having been taken by Barlow, Knab, Cresson and myself, 

 and by 1909 the species apparently became common over a large part 

 of its present range. The seasonal range, according to the records 

 in my possession, is from April to October inclusive. 



Eristalis rupium Fabricius. 



This species, which is also well known and widely distributed in 

 Europe, is here recorded for North America for the first time. Six 

 specimens, one male and five females, were recently sent me for iden- 

 tification bv Mr. E. M. Anderson, of the Provincial Museum, Vic- 

 toria, British Columbia. These were taken by Mr. Anderson at 

 Atlin, B. C, near the Alaskan boundary and about 100 miles inland. 



The well-marked brown spot on the middle of the wing will serve 

 to distinguish rupium from other species of this genus in boreal 

 America, except E. bastardii and E. occidentalis which are densely 

 pilose species, and E. saxorum from which it differs by its smaller 

 size, by the more reddish appearance of the male and the entirely 

 shining- third abdominal segment of the female.
