The principal motive in publishing the present paper in the desire to fulfill a promise made to Rev. J.H. Keen, several years agom to write a description of an apparantly new and very interesting Staphylinid discovered by him in British Columbia. For one reason or another I was compelled to defer this work, but having now an opportunity to comply with the wished of my valued friedn and correspondent of many years, the present occasio is made available to draw up a little paper, containing in addition a number of novelties received from various collectors from time to time.
