Abstract

The only published checklist of the Hydradephaga from the Maryland area is Ulke (1902) who records 65 species from the District of Columbia. The present paper lists 121 species as occurring in Maryland. Comparable lists for other states are as follows: Young (1954), 120 species from Florida; Folkerts (1978), 120 species from New York; and Brigham (1982) and Sanderson (1982), 115 species from North and South Carolina. Some of the identifications are questionable until generic revisions are completed. This is especially true of Hydroporus and Gyrinus.
