NORTH AMERICAN ACRIDIIDjE. 39 



Austral zones, but owing to its powerful flight of common 

 occurrence also in southern parts of Transition and Canadian zones. 

 Generally distributed from sea-beach to summits of highest moun- 

 tains, frequenting a great variety of habitats. Most plentiful in tall 

 growths of weeds and bushes, but found in injurious numbers only 

 in vicinity of Chattanooga in rank growth of bottom-land. 



Schistocerca alutacea Harr. 



South Carolina : Denmark, Aug. 15. 



Georgia: Savannah, Aug. 14 ; Tybee Island, Aug. 12, 13. 



Florida : Carrabelle, Aug. 9 ; Fort Barrancas, Aug. 3. 



Austral zones, including southern New England. Widely dis- 

 tributed, but local. A common inhabitant of the rank mixed growth 

 of grassy swamps. 



Schistocerca rubiginosa Scudd. 



Virginia : Cape Henry, Sept. 7 ; Virginia Beach, Sept. 7. 



South Carolina : Denmark, Aug. 15. 



Georgia: Tybee Island, Aug. 12, 13. 



Florida: Carrabelle, Aug. 9; Tallahassee, Aug. 8. 



Austral and Transition zones. Widely but locally distributed; 

 sometimes associated with 6*. alutacea, but typically found in drier 

 haunts. There is considerable variation in this species in color and 

 markings in the direction of alutacea. Possibly hybrids occur, but 

 typically these two species differ in color, structure, and haunts. 



Schistocerca damnifica Sauss. 



Virginia : Virginia Beach, Sept. 7. 

 North Carolina : Tarboro, July 7. 

 Austral zones. But two adults of this species were seen. 



Gymnoscirtetes pusillus Scudd. 



Georgia: Waycross, Aug. it, (juv.). 

 Florida : De Funiak Springs, Aug. 5. 



Lower Austral zone. This peculiar species was found locally 

 abundant at Waycross in the open lower, marshy portions of the 

 pine barrens, inhabiting a matted growth made up of pipewort, 

 sedge, and j uncus stems. A single specimen taken at De Funiak 

 Springs was found in a similar growth in a springy run. At both 

 places it was accompanied by Aptenopedes spJienarioides. (See PI. 5, 

 Fig. 2).
