14 FURTHER RESEARCHES ON NORTH AMERICAN ACRIDIID^. 



Hippiscus occur in old fields and pastures on dry soil, where the grass 

 is tall and interspersed with bushes. Several of these, together with 

 Spharagemon bolli, Melanoplus impudicus and luridus^ live in the open 

 forest, generally near grassy places. Schistocerca americana is almost 

 ubiquitous, among vegetation of all sorts. Melanoplus atlanis prefers 

 dry, grassy fields ; M. femoratus moist runs, the banks of streams, etc. ; 

 M. femur-rubrum damp, grassy fields; and M. strumosus the under- 

 growth of woods. Hesperotettix brempennis has been taken only on 

 bunch-grass (Andropogon), either in fields or openings in the forest. 

 The Tettiginse, with the exception of Tettigidea lateralis from moist, 

 sedgy runs, prefer somewhat exposed but rather moist soil of sandy 

 loam or the banks and beds of streams. 



From Valley Head, Alabama, the next stopping-place, the sum- 

 mit of Lookout Mountain was paid a brief visit, for the purpose of 

 comparison. At the point reached, the locust fauna was very similar 

 to that on Sand Mountain, but perhaps less numerous in species and 

 individuals. 



Anniston, in the east-central part of the State, was chosen as the 

 most convenient point of approach to Cheaha Mountain, the highest 

 summit in Alabama. Immediately about Anniston the collecting was 

 decidedly and inexplicably poor, both in species and individuals. 

 Twenty miles south, at Turnipseed's ranch near the foot of Cheaha, 

 a rich collecting spot was found, but only a very limited stay could be 

 made there. Several hours were spent on the summit of Cheaha 

 (2,000 to 2,400 feet) between Pulpit Rock and the top, and important 

 results were secured. 



The summit crest is covered with an open, stunted, fire-scarred 

 forest of oak and other deciduous trees, xerophytic in character, with 

 scattered boulders and occasional outcrops, a rank growth of bunch- 

 grass, and occasional shrubby patches. While not of sufficient eleva- 

 tion to reach a distinctly boreal zone, and too limited in area to greatly 

 modify the temperature of the air passing over it, here was found a 

 most interesting aggregate of species, as follows : 



Mermiria bivittata. Hesperotettix brevipennis. 



Orphulella pelidna. Melanoplus impudicus. 



Orphulella speciosa. Melanoplus viola. 



Arphia sulphurea. Melanoplus fasciatus. 



Hippiscus phoenicopterus. Melanoplus bivittatus femoratus. 



Dissosteira Carolina. Melanoplus tribuloides (new species). 



Spharagemon bolli. Podisma australis (new species). 

 Schistocerca alutacea.
