258 THE CANADIAN ENTOMOLOGIST, 



5 1. Pyritis mo?iiigetm, Hunter. — Taken by Harvey at Vancouver, May 



2, 1903, and again at Vernon. A number of specimens, only females. A 



specimen is in my collection from Victoria also. The species was 



described in 1895 from a single male specimen taken at Moscow, Idaho. 



As the female has not, to my knowledge, been described, I indicate here 



the characters. 



Very similar to the male, differing only in the following: Eyes widely 

 separated. Front broadly sulcate transversely, below the sulcus shining ; 

 in the sulcus and above brownish poUinose. Face above and on the sides 

 also brownish pollinose. The whole body, head and legs covered with 

 whitish or light yellowish pile ; the only black hairs present are those on 

 the eyes and aristae. 



I have not been able to compare with the male of this species, but 

 the female answers so well to the description that 1 have little hesitation 

 in describing it here. 



52. Pyritis Kincaidii (Coquillett) — {Volucella Kincaidii, Coquillett, 

 Ent. News, 1895, pp. 131-2.) 



Taken by Harvey at Vancouver, Feb. 14, 1901 ; Feb. 28, J 903; 

 April 12, 1902; also at Vernon, May 2, 1903. Four specimens, two 

 males and two females. 



This species is quite close to the preceding. I have been unable to 

 separate them by any marked anatomical characters, and yet they are 

 quite different in appearance. P. Ki?icaidii averages larger than P. 

 motitigefia, yet they intergrade in size. The chief difference to be noted 

 is in the colour of the pile, which in montigena is whitish or light 

 yellowish, while in Kincaidii it is dark reddish yellow. The females of 

 Kincaidii are exactly like the males in this respect, and, in my specimens, 

 show no tendency to intergrade in colour with P. mofitigefia. 



53. Sericomyia chalcopyga, Loew. — A common species at Port Ren- 

 frew, on dates ranging from June 30 to Aug. 16. Mr. Harvey has taken the 

 species at Vancouver, Apiil 12 and Oct. 3, and at Wellington, April 17. 

 The writer has taken the species also at Laggan, Alberta, Aug. 24, 1902. 



{Sericomyia militaris, Walker. Taken at Laggan, Alberta, Aug. 24, 

 1902, and will undoubtedly be found in Br. Col.) 



54. Arctophila flagrans, O-sten Sacken. — Port Renfrew, Aug. 10, 

 1902 ; Glacier, Aug. 20, 1902. A single male specimen taken at each
