During the summers of 1901–2, while at the Minnesota Seaside Station of Vancouver Island, Professor Raymond C. Osburn collected a number of Diptera, and during the these same seasons and the past summer Professor R. V. Harvey, of The Queen's School at Vancouver, British Columbia, collected in the same order. Since so little has been published on the Diptera of that province, we have thought that even a short paper on the Dipterological fauna would be of interest and probably of some value.
