At the request of Dr. James Fletcher, I am writing a few notes to accompany the three figures which have been made at his instance, and kindly presented by him. They represent three Staphylinidæ taken by me at Massett, on the Queen Charlotte Islands, and were prepared under the direction of Mons. A. Fauvel, the well-known specialist in that order, to whom also I am indebted for the determination of the beetles themselves.
