it would at once fly swiftly and silently away to the stem of a cat-tail, 

 apparently in a safe place, and would then, when approached, dodge 

 around to the opposite side and remain motionless, pressing itself to 

 the stem, which I noticed would almost invariably be the same color 

 as itself. It could then be taken by a stealthy approach and a 

 quick grasp of the hand, for it seemed to rely on its resemblance to its 

 support and would not take wing unless alarmed by a quick movement 

 or a too close approach. When badly alarmed I noticed several speci- 

 mens fly up into the trees and hide on the small twigs, as they had before 

 done on the cat-tails. Not one of the species was to be found on the 

 brownish rushes where Leptysma was common, which latter species 

 was precisely the color of its surroundings. The flight of this species is 

 much stronger and more rapid than that of L. marginicolUs , and owing 

 to this fact and the locality in which it is found , it is quite difficult to take 

 a specimen when thoroughly alarmed. Those specimens seen on the 

 meadow where Mitchell's Pond had once been were afforded poor cover, 

 as the grass was short, and I noticed that they would almost always 

 take flight when I was still a number of feet distant, no matter how 

 cautiously I approached. (M. H.) 



Leptysma marginicolhs (Serville). 



This species, which is somew^hat similar in habit to the preceding, is 

 represented by specimens taken at Thomasville during March and in 

 Leon county on March 22, 1904. 



This species was most numerous among the dried rushes on the edge 

 of the pond in Leon county mentioned as the habitat of the preceding 

 species. The specimens were easily alarmed by a quick movement, but 

 could be easily approached and grasped if this was done in a slow and 

 careful manner. They were as well protected by their color on these 

 brown rushes as the S. chlorizans were with their bright green colora- 

 tion on the cat-tails whose stems were the same color; the latter species, 

 however, showed much less confidence in its concealment and was 

 much more difficult to approach. (M. H.) 

 Schistocerca americana (Drury). 



This elusive and powerful species is represented by eight specimens 

 taken at Thomasville in January, March, May, October and December. 

 Leon county is represented by specimens taken in March. 



Much of the time this species is common in the open pine woods. 

 Its flight is powerful and it usually takes refuge on the pine trunks 

 over eight feet from the ground. Its color blends remarkably with the 

 bark, and it, remaining motionless, with hind femora drawn closely to 

 the body ready to spring, does not take flight until closely approached.
