MORSE: ORTHOPTERA OF NEW ENGLAND. 499 
Station near Boston, Mass., on salt-marsh at the side of the rail- 
road track; the locality has since been destroyed by the march 
of modern improvements. Whether the color had any relation to 
the salt-marsh environment, or to carbonaceous matter deposited 
from the smoke and cinders of trains remains to be determined. 
This is a slender-bodied Locust of medium size, graceful form, 
and elegant appearance which will be readily recognized when 
captured. It occurs locally in swamps and marshes in southern 
New England, sometimes on cord-grass (Spartina) growing in 
the tide-water ditches of salt-marshes, sometimes in the tall 
sedges and rank weeds of bushy inland meadows and swamps. 
It is usually common but not abundant where found. It is an 
alert and active Locust but seeks safety in trying to escape 
observation by sidling around out of sight behind the stouter 
stems of grasses and weeds rather than by flight, to which it 
resorts only when closely approached or alarmed. It leaps well 
and quickly, but its flight is comparativel}^ short. 
It inhabits only the warmer, southern part of New England 
and is a late-maturing species. It has been taken from July 22 
to August 30 at Cambridge, Faneuil, Newtonville, and Walpole, 
Mass.; Deep River, Niantic, North Haven, and Stamford, Ct. 
Walden reports it also from Branford, New Canaan, New Haven, 
Westville, and Walhngford, Ct., from August 25 to October 14. 
Immature examples were plentiful at Faneuil, Mass., on July 22.
