226 THYSANOPTERA AND ORTHOPTERA. 



frightened. About 25 or 30 yards may be covered at a single flight, 

 but usually much less. 



Scirtetica marmorata (Harris). 



July 20 to August 3. 



Open woods, grassy clearings, and roadsides in woods. 



This species flies with a clacking of the wings which is so rapid 

 as to be almost a buzz. 



Trimerotropis maritima var. interior E. M. Walker. 



July 4 to August 3. 



Grassy sand dunes and semi-vegetated beaches. 



This is a vigorous flier. A single flight covering 30 yards was 

 not uncommon, while one individual supposed to be of this species 

 was seen to fly up over the tre^ tops and was more than a hundred 

 yards away when it passed out of sight. When flushed, they start 

 off with direct and vigorous flight as if intending to go a long dis- 

 tance, but very often after flying eight or ten yards they turn sud- 

 denly to the left or right, execute a short half-turn of a spiral, and 

 alight on the sand or ground facing the disturber. 

 Circotettix verruculatus (Kirby). 



July 12 to August 3. 



Open woods and clearings, grassy roadsides and sand dunes. 



A favorite spot for this blackish species was a burned-over area 

 near Caseville, where they were almost indistinguishable when at 

 rest. If not disturbed, they would rise in the air, one, two, or three 

 at a time, and execute an irregular flight during five or six seconds. 

 One remained in the air 24.5 seconds. Often they took a spiral 

 course, not moving far from the place where they arose, but some- 

 times they would move off slowly in one direction. They never rose 

 more than two tcf four feet from the ground during such a flight. 

 They invariably clacked loudly with their Avings during all or a part 

 of each flight, unless flushed, when flight was almost noiseless except 

 just before alighting. 



Subfamily Acridiinae. 



Melanoplus atlanis (Riley). 



June 30 to August 6. 



Open Avoods, among grass or leaves; sandy or gravelly beaches 

 at least partly covered with grass or low bushes; grassy roadsides or 

 other grass plots, either dry or moist; among low herbs or tall weeds. 



Next to M. bivittatus femoratiis, this species was the most fre- 

 quently captured of any in the genus. 

 Melanoplus dawsoni (Scudder). 



July 12. 



Grassy places in meadows or open woods.
