ENTOMOLOGICAL NEWS VOL. LXV JULY, 1954 No. 7 My Last New North American Fleas By C. ANDRESEN HUBBARD, Tigard, Oregon The fleas listed here as new, bring to 50, the number described by the writer and clears from his desk the accumulation of odds and ends through the years. The types are all deposited in the U. S. National Museum, first paratypes in the British Museum. Thomomys and the Dactylopsylla Investigators realize the almost endless variety found in west-ern pocket gophers. Hall mentions 38 from Nevada, Bailey 15 from Oregon, around 10 are recorded from Washington. Their giant fleas (Dactylopsylla) are almost as variable. D. comis, the first of these northwest giants to be described, ranges every-where in the Cascade Mountains and east in Oregon and Wash-ington. West of the Cascades one finds a variable series in which the differences are to be found in the breadth of the VIII St. male, its apical angle, shape of its membranous appendage ; and apical outline of VII St. female. The four listed below as new are all between 4 and 5 mm. in length. Dactylopsylla comis scapoosei new subspecies Closest to D. c. comis but with VIII St. male very narrow, apical angle rounded but very flat and membranous flap ap-proaching the rectangular. VII St. female generally without undulations. Types were taken off Thomomys d. dout/lasi (type host) at Scapoose, Columbia County (type locality), OREGON on May 8, 1951. (169)
