FAMILY VII. TETTIGONIID^B. THE KATYDIDS. 



taken in Florida at Fernandiua, Atlantic Beach, Crescent City 

 and Enterprise, May 25 August 25 ; and at Raleigh, N. Car., and 

 Billy's Island and Spring Creek, Ga., June 7 Aug. 8. Sherman 

 and Brimley (1911) list it from Raleigh and Southern Pines, N. 

 Car., and Brimley (1908) states that at Raleigh it has been taken 

 only from mid-July to early August, both at light and on sugar, 

 but not in ordinary collecting. Xo one of the records given men- 

 tion more than two specimens from any one locality and most of 

 them only one. The female in the Field Museum was taken by 

 W. J. Gerhard at Bosky Dell, near Carbondale, southern Illinois, 

 on Sept. 27, 1909. This extends greatly its known range to the 

 north and west, all other records having been from North Caro- 

 lina to central Florida.
