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 Cajfion, 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

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 
tibia and tarsi fulvous pubescent,’ while in this specimen the 
femora only are “pitchy black,” the tibize and tarsi yellow, all
