THYSANOPTERA AND ORTHOPTERA. 225 



it was easily flushed and leaped three or four feet, alighting on the 

 ground unless the grass was dense; but some individuals concealed 

 themselves in clumps of grass when approached. 

 Camnula pellucida, probably, immature. 



June 25 to August 12. 



In same locations as adults (vide supra), and, in addition, among 

 low underbrush. 



Hippiscus tuberculatus (Palisot de Beauvois). 



June 15 to August 3. 



On bare or grass-covered- sand, and in open woods where the 

 ground is covered with a sparse growth of grass. 



The male of this species is a ready flier, and sometimes quite 

 hard to catch. The female is heavy and clumsy. The specimens 

 observed always alighted on the ground. Examination of a con- 

 siderable quantity of faeces of a female of this species indicates that 

 its food had been almost exclusively the sea sand-reed, Ammophila 

 arenaria. 



Dissosteira Carolina (Linnaeus). 



July 7 to August 6. 



Grassy fields, roadsides, open woods, clearings, on sand dunes 

 (among grass or on the bare sand), hay or wheat stubble, — in fact, 

 almost anywhere. 



This is one of the most nearly universal of all the Acridiidae in 

 the region studied, though not as abundant as several others. 

 Dissosteira Carolina, probably, immature. 



June 29 to July 24. 



In same locations as the adults (vide supra), and, in addition, 

 among low underbrush. 



Spharagemon bolli Scudder. 



July 7 to August 3. 



Meadows, clearings, roadsides, sand dunes, beaches, — all at 

 least partly grass-covered. 



The flight of this species is often accompanied by a rattling of the 

 wings. It alights upon the sand or soil, not on the vegetation. 

 Spharagemon bolli, probably, immature. 



June 30 and July 3. 



Localities similar to those given above for the adults. 

 Spharagemon wyomingianum (Thomas). 



July 11 to July 24. 



Grass plots, damp or dry; tall weeds; open sandy woods; bare or 

 grassy beaches. 



The habits of this species are similar to the preceding. Flight 

 is usually accompanied by a rattling of the wings unless the insect is
