variabilis Brim. This species seems to be very generally distributed 
over the State up to an altitude of about 6,000 feet. We 
have taken it on grassy areas. It seems to feed mostly upon 
salt grasses. Adults were just beginning to appear at Ft. 
Collins June 22, 1899 (Ball) and we have taken them up to 
Sept. 23rd. 
Specimens have been taken at Ft. Collins, Laporte, 
Windsor, Timnath, Greeley, Merino, Snyder, Julesburg,

bicolor Thom. A very common species on dry grassy slopes over 
all the eastern portion of the State, particularly, northward 
near, and for some distance within the first foothills. Speci¬ 
mens have been taken at an altitude of fully 8,000 feet. This 
insect doubtless causes heavy losses on the native pasture 
lands of the State.
