38 NORTH AMERICAN ACRIDIID^E. 



Austral zones. A characteristic xerophilous species widely 

 and generally distributed throughout the Southeastern States. 

 Along the seaboard in North Carolina and Virginia it meets, 

 mingles with, and apparently hybridizes with its northern con- 

 gener, T. maritima. (See PI. 3, Figs, i, 2; PI. 4, Figs, i, 2; PI. 5, 

 Fig. i, for illustrations of habitats, and pages 15 and 22 for further 

 remarks on these two species.)
