THE DIPTERA OF BRITISH COLUMBIA. 



(First Part.) 



BY JAMES S. HINE, COLUMBUS, OHIO. 



During the summers of 190 1-2, while at the Minnesota Seaside 

 Station on Vancouver Island, Professor Raymond C. Osburn collected a 

 number of Diptera, and during these same seasons and the past summer 

 Professor R. V. Harvey, of The Queen's School at Vancouver, British 

 Columbia, collected in the same order. Since so little has been pub- 

 lished on the Diptera of that province, we have thought that even a short 

 paper on the Dipterological fauna would be of interest and probably of 

 some value. 



These gentlemen have very kindly turned over their material, with the 

 exception of the Syrphidse, with the request that I should make the 

 determinations and publish the results. I have encountered more or less 

 difficulty in making these determinations, but have been ably aided in 

 some cases by Mr. D. W. Coquillett, of the U. S. National Museum. 

 Besides a number of specimens still undetermined, four new species have 

 been described from the material. Two of these are described in this 

 paper, one, Anthalia stiginalis, was described by Coquillett in the Pro- 

 ceedings of the Entomological Society of Washington, V. 268, and I 

 described the fine Crane-fly, Pedicia magnifica, in The Ohio Naturalist, 



III., 417- 



I have not considered the Syrphidse in this part of the paper. Pro- 

 fessor Osburn paid special attention to collecting the members of this 

 family, and has spent much time in studying them and comparing with 

 types in the U. S. National Museum. It is his intention to follow with a 

 second part and give full notes regarding the field observations taken on 

 many of the species. 



As the field-work for this paper was done by others, I have no 

 extended notes to offer, but in working over the material some few things 

 have suggested themselves. 



The list given below includes a number of species that have been
