The fauna of Puget Sound [as shown by a collection of fifty species of Hymenoptera from Seattle, Washington, kindly sent me by Prof. O. B. Johnson, of the University of Washington] is most like that of Canada, no genera differing.
Sphex Lucæ, Sauss, and Astata montana, Cress., are interesting exceptions.
