244 UNIVERSITY OF COLORADO STUDIES 
The following list gives the localities from which the species known 
to occur in the state have been collected. For the records prior to 1902 
I have not gone to the sources. I give them as listed by Beardsley. 
Beardsley’s own collections cover quite a number of years and are mostly 
from the vicinity of Greeley, at an altitude of about 4,600 feet. Here 
typical plains conditions prevail. Ward’s collections were made during 
the summer of 1903, from a group of lakes near Pike’s Peak at an altitude 
of about 10,500 feet. The conditions here are alpine. The collections 
by Juday were made from Twin Lakes, during the summers of 1902 
and 1903. These lakes have an altitude of 9,200 feet. During the 
summer of 1907 the writer made collections near La Junta (4,100 feet), 
near Boulder (5,300 feet), at Tolland on South Boulder Creek (8,850 
feet), and from Redrock Lake near Ward (about 10,000 feet).
