if ever, settling on the ground. If then approached, it dodges around 

 the object upon which it rests, much as does a squirrel under the 

 same circumstances. 



Of the distribution of the American locust Seudder has written: 

 "Excepting S. peregrina, which has crossed the ocean and colonized 

 another world, 8. americana is the most widely distributed member 

 of the geniis, and merits its name, ranging as it does from North 

 America east of the Great Plains and south to about latitude 40°; 

 through the West Indies, Mexico and Central America to South 

 America, where it occurs as far as Columbia in the west and Argen- 

 tina in the east, though the records of its occurrence in South Amer- 

 ica are few. North of north latitude 40° or thereabouts, sporadic 

 cases of its appearance are recorded, notably in Massachusetts and 

 southern Ontario; these are doubtless accidental visitants, tlying 

 from their proper home farther south."
