218 THE CANADIAN ENTOMOLOGIST. 



22. Syrphus arciiaiiis (Fallen). — Common and widely distributed. 

 Taken at Port Renfiew, July 25, 1902; Victoria, July 17, 1901 ; and 

 Field, July 15, 1902. Harvey has taken it at Wellington, April 15, 1903, 

 and at Mt. Cheam, Aug. 5, 1903, and the writer has it also from Laggan 

 and Banff, in Alberta. The variety lapponicus occurs along with the 

 typical form. 



23. Syrphus amalopis, Osten Sacken. — Two specimens, male and 

 female, from E. M. Anderson, are in my collection marked "Br, Col.," 

 but with no other data. They are presumably from Victoria. This 

 supposedly eastern species has been recorded commonly from Alaska 

 (Coquillett, 1900). 



24. Syrphus intriidens, Osten Sacken. Common at Port Renfrew, 

 June 22 to July 5. A specimen taken at Victoria was sent me by E. M. 

 Anderson, and Harvey has taken it at Vancouver, May 16, and at Mt. 

 Cheam, Aug. 9, 1903. Also taken at Liggan, Alberta. Considerable 

 variation is shown in size, and in shape and size of abdominal markings, 

 but they seem to intergrade completely. 



25. Syrphus contumax, Osten Sacken. — A single specimen taken by 

 R. V. Harvey at Grouse Mt., July 19, 1903. Kincaid found the species 

 common at a number of places in Alaska (Coquillett, 1900). 



26. Syrphus nientalis, VVilliston. — Port Renfrew, June 30, 1901 ; 

 Glacier, July 20, 1901. Taken by Harvey at Vancouver, April 10, and at 

 WeUington, April 15, 1903. Taken also at Laggan, Alberta, July 22, 

 1 90 1. Has been taken in Washington and Alaska. 



27. Syrphus disjectus, Williston. — Taken by R. V. Harvey, at 

 Vancouver, July 26, 1902. A single specimen. 



28. Syrphus velutinus, Williston.— A single specimen of this inter- 

 esting species was taken at Mt. Cheam, Aug. 9, 1903, by Harvey. The 

 type locality is Oregon. Kincaid took a single specimen in Alaska 

 (Coquillett, 1900). 



29. Syrphus pauxillus, Williston. — This species was described by 

 Williston in his Synopsis of N. A. Syrphidse, 1886, from a single female 

 specimen taker: in New Mexico. Since that time I have not been able to 

 find any reference to it in the literature of western Syrphidfe. Three 

 specimens in my collection without doubt belong here. One of these, a 

 female, was taken by the writer at Banff, June 17, 1901. Another female
