This species was found only in the vicinity of areas of nat- 

 ural woodland of some size. In the Devils-Stump Lake region 

 it was rather common in brushy fields and along paths and 

 roads through the woods and through patches of tall shrub- 

 bery bordering them. In the Turtle Mountains specimens 

 were taken in the grassy margins of groves of aspen and bal- 

 sam poplar, among scattered clumps of beaked hazel, rasp- 

 berr}- bushes, and other shrubbery. Others were found along 

 the. edges of roads running through the woods and on the dry, 

 gravelly beach of Lake Upsilon, near the edge of the willow- 

 aspen thicket which bordered it. 



Chloealtis conspersa is probably common throughout the 

 Red River Valley and the Drift Prairie Plain regions, along 

 the streams and around the lakes where they are bordered 

 with natural forest. Neither this nor any of the other species 

 of Orthoptera typically associated with woodland conditions 

 were found in any of the small groves planted around farms 

 on the originally treeless prairie, but it is probable that in 

 time the distribution of these forms will be considerably modi- 

 fied by this artificial extension of forest habitats into the 

 prairie region.
