In Part I. of this paper Professor Jas. S. Hine has given a list of the Diptera of British Columbia in all the families except the Syrphidæ. While connected with the Minnesota University Seaside Station at Port Renfrew, on Vancouver Island, during ghe summers of 1901 and '02, the present writer paid especial attention, as far as time permitted, to the collection of Syrphids, hence the list of species in this family is much more complete than in other families which were picked up incidentally.
