"212 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERa) 



Georgia, 13.9-15.9; Cedar Keys, Florida, open-sigmoid, 13.2- 

 14.1, arcuate, 12.4-14.6 mm. 



The genicular areas of the caudal femora are not darkened, 

 the genicular lobes are normally bispinose but occasionally uni- 

 spinose; the caudal femora are elongate but with the proximal 

 portion more swollen than in spartinae, the ventro-external margins 

 are unarmed in all but two of the ninety specimens from New 

 Jersey before us, in the more southern material these margins are 

 armed as follows in forty-one perfect specimens examined: 

 Number of spines, 0-0 0-1 0-2 1-1 1-2 2-2 



Number of specimens, 24 6 5 3 1 2 



The present insect appears to be absolutely limited in distribu- 

 tion to the salt-marsh tidal flats. It is known from Ventnor, 

 New Jersey, to Cumberland Island, Georgia, on the Atlantic 

 Coast, and from Cedar Keys, Florida, on the Gulf coast. 



Specimens Examined: Previously recorded, over 30. Here recorded, 1.38; 

 67 males, 54 females, 5 immatm-e males and 12 immature females.
