432. Selasphorus platycercus (Swainson)—BRoOAD-TAILED HUMMINGBIRD. 
During the summer of 1891, Bruner saw on several occasions on 
the Pine ridge in Sioux and Dawes counties a species of humming- 
bird which he identified as this one, and a later intimate acquaintance 
with it in Colorado confirmed his identification. The hummingbird 
reported by J. M. Bates in Bruner’s list from Cherry county (Valen- 
tine) according to his own judgment also belongs here since he later 
identified the Broad-tailed at Bassett, Sept. 10, 1899, thus establish- 
ing its range half way across the state. (See Proc. N. O. U., I, pp. 
16-17.) Inthe adjacent states of Wyoming and Coloraco this species 
is common. 
EXTRALIMITAL: 433. S. rufus (Gmelin), the Rufous Humming- 
bird, is a western species which is fairly common in Colorado and has 
been taken at Cheyenne, Wyo., only about 60 miles from the Nebraska 
line.
