BULLETIN 94. 
I am calling this species is common in the northern plains 
portion of the State upon grassy areas and we have taken it 
in the foothills to an altitude of 5,500 feet. The males meas¬ 
ure from 15 to 18 mm. and the females between 18 and 21 
mm. in length. O11 going south this form gives way to a 
larger and longer winged form that I am calling pratorum. 
Scndd. 
The specimens have been taken at FT Collins, Laporte, 
Windsor and Greeley. Adults have been taken as early as 
July 22, and as late as September 17th.

pratorum Scndd. What I am calling this species is abundant in the 
northern portion of the State east of the foothills and is also 
common in the southern portion. The males range between 
18 and 20 mm. and the females between 21 and 24 mm. in 
length. 
The specimens in the College collections have been taken 
at the following points: Ft. Collins, Greeley, Sterling, Sny¬ 
der, Pueblo, Rockyford, Lamar and Holly in Colorado, and 
Stratton in Nebraska. See Orphulella pelidna. 
salina Scndd. This low-ground species has been taken by ns upon 
the west slope only in the vicinity of Delta and Grand Junc¬ 
tion from July 7 to Sept. 23. On Sept. 17th, 1903, it was 
noted as the most abundant grasshopper on salt-grass, Dis- 
tichlis maratimci , growing through a heavy deposit of alkali 
on low ground near Delta. (Gillette.)

CHLOEALTIS Harris. 
©onspersa Harr. We have taken this species on five different dates 
at altitudes from 5,500 to 6,000 feet in the foothills west of 
Ft. Collins. The captures have all been from a single canon 
known as Horse-tooth Gulch and between July iotli and Aug. 
12th. A single female was also taken in the foothills near 
Boulder July 23rd, 1901. 
The females vary between 22 mm. and 24 mm. in length 
and their elytra vary between 8 mm. and 10 mm. in length. 
The males are from 18.5 mm. to 21 mm. in length and their 
elytra are from 9.5 mm. to 12.5 mm. long. In three of the 
males the entire sides of the pronotum to the lateral carinse 
are black. In two others the lower portion is brown. The 
females lack the black dash upon the upper posterior angles 
of the sides of the pronotum. There are other reasons, partic¬ 
ularly in the elytral venation of the males, for thinking that 
this Colorado form may be a new species.
