One of the most common of the campestral Orthoptera 

 occurring in the eastern part of the state. In the eastern local- 

 ities it was found in nearly all grassland habitats and was 

 common and in many places abundant in dry pastures and 

 stubble-fields and on the sandy flats around the lakes. In the 

 Turtle Mountains it was very numerous in brushy clearings, 

 and was also taken in a tall growth of rank herbage in a low, 

 moist meadow. In the grain fields and on the waste lands 

 covered wnth Russian thistle in the vicinity of Bottineau it 

 was abundant ; it is probably of considerable economic im])or- 

 tance, in spite of its diminutive size. In the western part of 

 the slate Mclanophis daicsoui seemed to be less common ; at 

 Amidon it was rather scarce on the dry. grassy plains, on the 

 slopes of the buttes. and on grassy ridges among the Bad 

 Lands, while Miss Olson took only a single specimen at Wil- 

 liston. and did not find it at all at Buford or Medora. That 

 this scarcity was not due to the lateness of the season is shown 

 by the fact that after leaving Amidon I found it to be com- 

 mon at Fargo in similar situations to those in which it was 

 taken at Devils Lake. 



A number of macroj^terous specimens were taken in various 

 parts of the state, as follows: Devils Lake, i male. 5 females; 

 Shevenne River, i male, i female : Turtle Mountains, 1 female ; 

 Fargo. 2 males, i female : .Amidon. i female ; in all a total of 

 4 males and 9 females. Most of these were taken by sweep- 

 ing. The macropterous form is very rare in this part of the
