Since the publication of Whitehouse's Catalogue of the Odonata of Canada and Alaska (1) several papers on Canadian Odonata have appeared that have added to our knowledge of the composition and distribution of this order of insects in Canada. Two species have been added to the Canadian list, viz., Celithemis martha Wmsn. from Nova Scotia by Cook (2) and Somatochlora sahlbergi Trybom from the Mackenzie District N.W.T., by Walker (3). Cook adds also the following that are new to Nova Scotia: Enallagma cyathigerum Charp., Gomphus spicatus Hagen, G. ventricosus Walsh, Celithemis elisa Hagen, Libellula pulchella Drury, L. Lydia Drury and L. luctuosa Burm.; and one new to New Brunswick, Aeshna interrupta interrupta Walk. Walker (3) adds two to Labrador ( Lestes disjunctus Selys and Libellula quadrimaculata L.), two to Manitoba ( Somatochlora septentrionalis Hagen and Leucorrhinia patricia Walk.) and four to the Mackenzie District, N.W.T. ( Lestes congener Hagen, Nehallenia irene Hagen, Somatochlora albicincta Burm. and Sympetrum obtrusum Hagen) besides Somatochlora sahlbergi , already mentioned. He also gives a list of 14 species from the Yukon Territory, from which only two species were previously known .
