MORSE: ORTHOPTERA OF NEW ENGLAND. 453 
there is heard an ahnost continuous succession of purring flights 
as the handsome creatures seek out and pay court to their waiting 
mates. Not only while flying do they produce sounds, but I 
have seen and heard them stridulate while at rest by rasping the 
hind thighs against the tegmina (for details see Journ. N. Y. Ent. 
Soc, vol. 4, p. 16-20, 1896). 
Tliis is a shy species and flies readily and strongly, often to a dis- 
tance of several rods, and its rattling crepitation is of greater 
volume than that of its spring-time congener, A. sulphurea. It is 
equally common, perhaps even more numerous locally, than the 
latter and frequents the same situations: old fields and bushy 
pastures on sandy soil. In the one it is often associated with the 
Collared or Scudder's Locust, in the other with Boll's Locust. 
Adults have been taken from the last of July till November, in 
the Austral and warmer parts of the Transition zones of New 
England: in middle New Hampshire (Scudder); Andover, Bel- 
mont (Maynard), Dedham, Wellesley and \'icinity, and Nan- 
tucket, Mass.; Wickford, R. I.; Thompson, South Kent, New 
Haven, Greenwich, and Stamford, Ct. 
Spring Yellow-wixged Locust.
