dant as anywhere. It extends into the foothills for ten or fif¬ 
teen miles in places and occurs as high as 7,000 feet in altitude, 
at least. 
The native food plants are Bigclovia (rayless goldenrod) 
and Gutierrezia eat ham ice. 
We have records of this species in the following places 
within the State: Ft. Collins, Dutch George’s, Windsor, 
Greeley, Sterling, Wray, Boulder, Denver, Colo. Springs, Pu¬ 
eblo, Rockvford, Das Animas, Lamar, Nepesta and Holly. 
Adults have been taken as early as July 2, 1901, at Ft. Col¬ 
lins and they were still abundant and mating freely at the foot¬ 
hills west of the town as late as Oct. 8, 1902 (Ball). 
This species has not acquired, an appetite for cultivated 
plants and its native food-plants are not of economic value. 
PODISMA Latreille. 
cfodgei Thom. This is distinctly a mountain species. We have 
taken it from just inside the first foothills at an altitude of 
5,500 feet to 12,000 feet altitude upon the mountains. From 
8,000 to 10,000 feet it is a rather abundant species. Food- 
plants unknown. 
We have taken this species at the following Colorado 
points: Ft. Collins (foothills), Livermore, Dutch George’s, 
Home, Ward, North Park, Lizard Head, Pike’s Peak 12,000

that vicinitv. The hind tibiae are universallv red.
