In the writer's list of the Odonata of Ontario fifty species were recorded from the Kenora District of Ontario and only one from the Rainy River District. Thirty-five are reported from the vast northern part of the District known as the “Patricia Portion” and twenty-three from the southern part. The records from the Patricia portion are all from three widely separated localities but probably give a fair general picture of the odonate fauna of these northern latitudes. The records from the southern part of the District, on the other hand, are almost entirely from one locality, Minaki (approx. 50° N. Lat., 9° W. Long.) and are quite inadequate even for that one locality, some of the commonest regional species not being included.
