BRITISH COLUMBIA SYRPHID.E, NEW SPECIES AND ADDI- 

 TIONS TO THE LIST.

in a former paper (Can. Ent., Vol. XXXVI, Aug. -Sept., 1904) the 

 writer recorded seventy-eight species in this family of Diptera for British 

 Columbia, and suggested that a complete list would probably include 

 twice that number. Undoubtedly that estimate was far too small, if the 

 number of species which have been added in three years by a little 

 sporadic collecting is any criterion. With the present additions the list is 

 swelled to more than one hundred and twenty-five. With the exception 

 of ten species of my own collecting not recorded in my former paper on 

 account of uncertainty of determination, and nine species added by 

 Messrs. Currie and Dyar, of the U. S. National Museum; the material for 

 this additional list has been taken by local entomologists. Especial 

 reference must be made to the excellent work of Prof. R. V. Harvev, of 

 Queen's School, Vancouver, to whose careful collecting twenty-two of the 

 additions are due. The remainder were taken by Messrs J. W. Cockle, 

 of Kaslo ; R. S. Sherman, of Vancouver, and A. W. Hanham. In 1906 

 Messrs. Harvey and Sherman made a tour through the Hope Mts. and 

 along the Nicolum River, securing a fine lot of specimens. In 1903 

 Messrs. H. G. Dyar, R. P. Currie and A. N. Caudell, of the U. S. 

 National Museum, collected in the Kootenay country, and incidentally 

 took forty-one species of Syrphidae and added nine species to the B. C. 

 list. Mr. D. W. Coquillett has identified this collection, and very kindly 

 turned over the results to me for publication in the following list. The 

 species resting entirely on his identification are so accredited in the list. 

 My thanks are due to Mr. Coquillett for permission to study carefully the 

 collection of Syrphidaa, containing many of the type specimens, in the 

 National Museum. 



I. Micro don tristis, Loew. 



The form tristis taken at Kaslo, June 5, 1906, by R. P. Currie, and 

 again by J. W. Cockle on June 5, 1906. The form. cotJmrnatus was 

 recorded in our previous list.
