36. Helophilus shni/is, Macquart. 



Kaslo, June 3, 1903, H. G. Dyar, and July 20, 1903, R. P, Currle ; 

 Vernon, Aug. 15, 1904, R. V. Harvey. I 



37. Helophilus conostomus, Williston. ' 



One specimen taken by Harvey at Vernon, Aug, 12, 1904. j 



-^Z. Helophilus porcus, Walker. j 



As far as 1 am aware this species has never been recorded since ' 

 Walker described it (List, etc., HI, 551), and recorded it for the Hudson 

 Bay Territory. Osten Sacken (Cat. Dipt., 250, note 235) says: "It is 

 represented in the British Museum by two (male and female) specimens. ! 

 I have never seen it elsewhere." There are in the U. S. National^ 

 Museum three unrecorded specimens, one male from Ottawa, Canada, andj 

 a male and female from North Mt., Pennsylvania, taken June 8 by Mr. C.I 

 W.Johnson. The specimen in my possession, from British Columbia,' 

 was taken at Kaslo by Mr. J. W. Cockle (date not given). The species,; 

 though apparently rare, seems to be of wide distribution through boreal 

 America. • 



39. Merodon equesiris, Fabricius. i 



This species has been taken previously a number of times inj 

 Am.erica, but it has always been assumed that it was in each case an j 

 accidental introduction from Europe in plant bulbs in which the larvpel 

 live. The occurrence of the species in several localities, and especially; 

 the number taken in British Columbia, make it seem certain that it| 

 properly belongs to our North American fauna. Mr. Harvey has taken 

 numerous specimens at Vancouver, frequenting especially the flowers ofi 

 the Salmon-berry (Rubus spectabilis). I 



40. Xylota fnargifialis, Williston. ' 

 A male of this species taken by Harvey at Duncan, April 19, 1906,1 



agrees in all respects with Williston's type from the White Mts. of New I 

 Hampshire. The species has also been taken in New York, but neverl 

 before in the west. j 



41. Ferdinaiidea (Chrysochlamys) croesus, O. Sacken. ; 



A male of this fine species was taken by Harvey at Victoria, June 8,| 

 1906, on a flower of the Yellow Hawk-weed (Hieracium). The species haS; 

 previously been known from Utah and Washington southward. i
