at this locality was somewhat like the prairie at Colorado Springs, but 

 not nearly as productive. On the hillside near the Pike's Peak railroad 

 station (elevation 6,700 feet) Orthoptera were plentiful among the 

 high grasses and scrub oak thickets. The Garden of the Gods (eleva- 

 tion 6,300 feet) proved everywhere unproductive except a small field 

 of tall grass near the Manitou street-car line. Many species were to 

 be found here in numbers. 



Pike's Peak. The' summit of Pike's Peak (elevation 14,147 feet) is 

 a mass of huge boulders with no apparent vegetation. The region 

 about Windy Point (12,000-12,300 feet) is treeless and very steep. A 

 short but sturdy grass grows everywhere that the quantity of huge 

 jagged rocks permit, and in this grass a few species of Orthoptera 

 such as Gomphocerus clavatus, Melanoplus altitudinum, fasciatus and 

 monticola were quite plentiful. 



Along the timber-line (11,578 feet) in the stunted vegetation Orthop- 

 tera were somewhat more varied, but not as interesting as those at 

 Windy Point. At Middle Hudsonian (elevation 10,500 feet) and above 

 the pump station (elevation 10,100 feet) the forest of quaking aspen 

 was exceedingly unproductive and very few specimens were seen. In 

 Dark Canon (elevation 8,900-9,000 feet) in spite of an abundance of 

 grass few Orthoptera could be found, although other forms of insect 

 life were plentiful. On the densely wooded upper slope of Dark Canon 

 work was attended with less success than in the burned-over forest. 



Cripple Creek, Teller Co., elevation 9,591 feet. The few specimens 

 taken at Cripple Creek were from the tailings about the mines. 



Fort Morgan, Morgan Co., elevation 4,338 feet. A rank growth of 

 weeds along the railroad track at this place swarmed with Orthoptera, 

 and in a few minutes a number of interesting forms were taken.

Antlers, Colorado, Aug. 15, 1 immature $ . 



This specimen is referred to this species with some uncertainty, as it 

 may represent L. horealis Bruner, which, however, is of doubtful 

 validity.^ 



This individual was taken on dry soil among dense beds of cactus 

 and sage.
