43. SphcRrophoria micrura, Osten Sacken. — Two females from Port 

 Renfrew, one July 6, 1901, the other Aug. 16, 1902. The male was 

 taken at Seattle, Wash., July 15, 1901. 



44. Sphcerophoria sulphiiripes (Thompson). — One male specimen, 

 taken at Glacier, July 20, 1901, belongs here questionably. It lacks the 

 characteristic bunch of yellow pile on the hypopygium of cylmdrica, but 

 otherwise resembles that species quite closely. 



45. Sphcerophoria melanosa, Williston. — A single specimen taken by 

 Harvey at Vancouver, May 3c, 1903, agrees quite well with Williston's 

 description, except that the cheeks are brownish instead of shining black. 



46. Sphegina infuscata,'Loev!. — Not common. Port Renfrew, July 

 6, 1 90 1. A specimen from Mr. Harvey, Vancouver, April 12, 1902. 

 Taken at Lowe Inlet by Kincaid, June 3 (Coquillelt, 1900). The writer 

 has taken the species also at Laggan, Alberta, Aug. 23, 1902. Two other 

 specimens taken by Harvey, one at Vancouver, March 28, 1903, and one 

 at Wellington, I place here provisionally. They are much larger and 

 darker than the typical form, and may be distinct. 



47. Spheghia lobata, Loew. — ^Not common. Port Renfrew, July 3, 

 1901 ; Glacier, Aug. 20, 1902. These show no difference from Ohio 

 specimens. 



48. Baccha obsairicornis, Loew. — A single specimen from Port 

 Renfrew, July, 1901 ; one specimen from Harvey, Vancouver, May 30, 

 1903. Taken at Lowe Inlet by Kincaid, June 3 (Coquillett, 1900). A 

 single specimen was taken also by the writer at Seattle, July 15, 1901. 



49. Myiolepta beila, Williston, A single specimen of this fine species 

 taken at Port Renfrew, June 30, 1901. 



50. Volucella facialis, Williston. — Taken by Harvey at Vancouver, 

 May 17, 1902, and May 30, 1903. The writer has taken the species at
