grass and low bushes in barren fields 

 and pastures on dry, upland soil. It is 

 rather shy, flies readily and strongly, 

 and will give the collector plenty of 

 exercise in the warm days of September. 

 Its rattling stridulation is somewhat 

 louder than that o'i sulphnrea. 



My earliest captures are on July 30, 

 latest on Oct. 30. I have specimens 

 from Wellesley and vicinity, Dedham 

 and Belmont (Maynard), Mass. ; Wick- 

 ford, R. I. ; Thompson, So. Kent, 

 New Haven, Greenwich and Stamford, 

 Conn. Scudder reports it from middle 

 New Hampshire, and Henshaw has 

 taken it on Nantucket.

This species is not likely to be mis- 

 taken for any other save its congener, 

 from which it may be readily distin- 

 guished by the Key. It is usually paler 



in color than xantJioptera, especially 

 the 9 , which is sometimes pale yellow- 

 ish brown. Both sexes are apt to 

 become darker with age. A $ fiom 

 Thompson, Ct., has a large part of the 

 hind margin of the tegmina very pale, 

 contrasting strongly with the general 

 color, a peculiarity often seen in western 

 species of the genus. 



This very common and widely distri- 

 buted locust is found nearly everywhere 

 in dry pastures in spring and early 

 summer, its rattling stridulation being 

 one of the constant features of a ramble 

 in such places at that season. Its flight, 

 particularly that of the $ , is less 

 extended than that of xauthoptcra, 

 being often limited to a few feet but 

 sometimes continued for three or four 

 rods ; its course is often circling, with 

 an aljrupt curve and a sudden drop into 

 the grass and bushes at the end. 



Adults begin to appear about the 

 middle of May — my earliest capture 

 is the 19th ; it is common in June and 

 early July and scattering individuals 

 may be found even in early September. 



It is found throughout New England. 

 I have examined specimens from Nor- 

 way and Deering, Me. ; Berlin Falls 

 (Henshaw) and Hanover, N. H. 

 (Weed); Brattleboro, Vt. (Mrs. J. B. 

 Powers) ; Wellesley and many towns 

 in its vicinity, Winchendon, Wood's 

 Holl, West Chop, M. V., Mass. ; New 

 Haven, No. Windham, So. Kent, 

 Stamford, and Thompson, Ct.
