oration it attracts but little attention among the crowds of 

 larger Melanopli, but it is probably responsible for a consid- 

 •erable amount of damage to crops in the central and western 

 parts of the state. 



Melanoplus confnsus Scudder. — Devils Lake, July 23, 19 19, 

 I female ; July 19-22, 1920, 6 males, 2 females ; Stump Lake, 

 July 24, 1920, I female; Williston, July 24, 1920, 3 males; 

 Medora, July 29-31, 1920, 2 males, i female; Amidon, Aug. 

 ^1-25, 1920, 6 males, 2 females. 



Though nowhere found in numbers, this species seemed to 

 be rather generally distributed through the state in dry grass- 

 land habitats. In the east it was taken in dry pastures, stubble- 

 iields, and on the flats around the lake shores. At Williston 

 it was taken on the grassy railroad right-of-way on the fiats 

 of the Missouri River. At Medora it was found among scat- 

 tered vegetation of dry grasses and Artemisia on dry, sandy 

 soil on the slopes of the buttes. It was rather scarce at Ami- 

 don ; specimens were collected on the sparsely vegetated mesa 

 top of Black Butte, on the plains near town, and on the sparsely 

 vegetated slopes where the uplands "break" into the Bad 

 Lands. 



Melanoplus keclcri luridus (Dodge). — Devils Lake, Aug. 26, 

 1919, 2 males, 2 females; Fargo, Aug. 31, 1920, 15 males, 9 

 females. 



This species is probably of common occurrence in the east- 

 ern part of the state, but owing probably to its late appearance 

 in the adult stage it was taken in only two localities. At Devils 

 Lake it was found on the grassy slopes of Sully's Hill; at 

 Fargo, in a dry field among a sparse growth of low grass and 

 weeds intermingled with patches of bare soil.
