214 THE CANADIAN ENTOMOLOGIST. 



about Lake Agnes, over 7,000 feet high, and 17 taken at Banff, Alberta, 

 are given mention in the following list. 



Besides the foregoing taken by myself. Professor R. V. Harvey, of 

 Queen's School, Vancouver, the energetic secretary of the British 

 Columbia Entomological Society, has aided materially in increasing the 

 list. He has very generously turned over to me all his Syrphids for 

 study, and I take great pleasure in acknowledging him as a " silent 

 partner" in the work on which this paper is based. Most of the records 

 from Vancouver and all from Mt. Cheam, Grouse Mt., Vernon and 

 Goldstream are from his material. My thanks are due also to Mr. Ernest 

 Anderson, of the Provincial Museum at Victoria, for certain specimens. 



The work of the present paper seems to bridge over a considerable 

 gap in our knowledge of the distribution of this family in the west. 

 Osten Sacken, Bigot, Loew, Williston, Snow, Hunter and Coquillett have 

 studied the Syrphids of the Western United States, and Hunter, Johnson 

 and Coquillett have recorded about 50 species from Alaska, but in all the 

 literature at my command I have failed to find reference to more than a 

 paltry half dozen species from British Columbia. The only papers, to 

 my knowledge, that make any reference to British Columbia species are 

 Hunter's "Contribution to the Knowledge of North American Syrphidte. 

 — n." (Canadian Entomologist, June, 1897), in which two species are 

 described from British Columbia, and Coquillett's Diptera of the 

 Harriman Expedition to Alaska, in which three species are mentioned 

 from Lowe Inlet. The present paper includes 78 species. It is hardly 

 worth saying that the collecting is only just fairly begun, and the work 

 done only serves to indicate the richness of the Syrphid fauna in that 

 region. Careful collecting at different seasons of the year and in different 

 parts of that vast and varied territory should almost, if not quite, double 

 the present list. 



Most of the species recorded for Alaska will be found recorded for 

 British Columbia in this paper, many of the mountain species of Colorado 

 and other western States are also found in the mountain regions of British 

 Columbia, and the coast species of California and Oregon are taken in 

 the warm inland sound region about Victoria and Vancouver. The fauna 

 of the open coast at Port Renfrew is distinctly more northern than that of 

 Vancouver, though the latter jolace is farther north. One thing note- 

 worthy in the present list is the large number of Old World species. 

 This observation falls in line with what Williston has already noted for
