228 • Psyche [December SOME ADDITIONS TO THE DIPTERAN FAUNA OF NEW ENGLAND. By Charles W. Johnson. Boston Society of Natural History. Pogonosoma dorsatum Say. A specimen of this species was obtained by Mr. F. A. Sherriff at the base of Mt. Washington near Fabyan, N. H., July 7, 1910. I am not aware that the species has been collected east of the Rocky Mountains since it was described by Say from "near Philadel-phia." It has been recorded from Washington (Williston) and Idaho (Aldrich). Specimens are in the writer's collection from Bear Creek Canon, Colo., June 8, 1897 (Oslar), and Estes Park, Colo., July, 1892 (Snow). Pogonosoma melanoptera Wiedemann. In the collection of the American Museum of Natural History is a specimen of this species collected by Prof. W. M. Wheeler at Woods Hole, Mass., July 18. The distribution of the species would indicate an austral form. It has been recorded from Flor-ida (Williston), South Carolina (Schiner), Maryland (Mus. Comp. Zool.) and New Brunswick, N. J. (Dr. J. B. Smith). Specimens are in the writer's collection from Alabama, Pendleton, N. C, June 7, 1895, and Philadelphia, Pa., July 5, 1898. Ceraturgus nigripes Williston. One specimen collected on the side of Mt. Equinox, near Man-chester, Vt., June 5, 1910, at an elevation of about 2,000 feet. The specimen agrees with the description of C. nigripes, except in two minor details. The wings are not "pure hyaline," but grayish with a distinct brownish tinge along costa and the outer half. The legs of C. nigripes are described as "pitchy black, the tibiffi and tarsi fulvous pubescent," while in this specimen the femora only are "pitchy black," the tibiae and tarsi yellow, all
