son. "It is extremely common, 

 even abundant locally, through- 

 out the northern part of New 

 England, being probably the 

 most numerous in point of indi- 

 viduals of any of our Oedipod- 

 imp. It is found in dry grassy 

 pastures and other untilled land, 

 preferably on high ground. The 

 flight is silent or slightly rust- 

 ling, usually low, short and di- 

 rect, resembling that of a large 

 Mclanoitliis; when with the wind, 

 however, it is occasionally pro- 

 longed for several rods in a 

 straight line."

Scotia and New England, its 



southern limit east of the Mississippi being Monterey, Va., north- 

 ern Pennsylvania and northern Indiana and Illinois. West of 

 that stream it occurs as far south as western Nebraska and Cha- 

 ma, New Mexico, and is abundant in California. In some locali- 

 ties it occurs in sufficient numbers to be ranked as a serious pest. 

 Gooderham (1017, 20) says that in Nova Scotia it is very com- 

 mon and their most injurious locust. In Idaho and Utah it has 

 often done much damage to growing crops, so much so, indeed, 

 that it was the subject of a special circular issued by the United 

 States Division of Entomology (Simpson, 1903). 



Writing of it in Minnesota, Somes (1914, 44) says: 

 "In the field it is apparently more free from the attacks of Trombid- 

 ium and other parasites and less susceptible to fungus diseases than the 

 Melanopli, although confined in our cages it died off very largely from 

 fungous troubles. Normally it is found on high, dry soils and at times in 

 some abundance even in the more open parts of forests. Its flight is 

 swift and direct without marked aerial stridulation. In the field this 

 species oviposits during the latter part of August, the pods being rather 

 short, stout, considerably curved, and not firmly cemented. These pods 

 are deposited just below the surface of the soil, among the roots of grasses 

 or in some c?ser even above the surface amid the dead grass, and contain 

 from 20 to 30 eggs each"
