REHN AND HEBARD 403 



slightly smaller, the male proportions are quite similar to those 

 of the female. 



The ventral margins of the cephalic and median femora are 

 almost always unarmed, bearing rarely a single very small spine; 

 the ventral margins of the caudal femora are armed with very small 

 spines with the adjacent areas of the femora sometimes very weakly 

 darkened; in the series before us the number of spines is: internal 

 2-8, external 2-5. 



The green color phase is usually decidedly more numerous than 

 the brown. 



The present insect is an inhabitant of the grasses in waste fields, 

 along the borders of marshes and in the drier portions of the 

 marshes proper, and is usually to be found in large numbers. The 

 song is of the exact pitch of that of ^V. lyristes but weaker (as in 

 N. palustris), a continuous zeeeeeeeeee. In New Jersey the species 

 is the last of the genus to appear, reaching the adult condition 

 toward the end of August. 



The present species is laiown from Westville, Connecticut, 

 southward to Daytona, Florida (the authors' Chokoloskee, Flor- 

 ida, record of this species is based on material the labelling of 

 which we have subsequently found cause to question, and the 

 record is therefore discredited). Westward in the Mississippi 

 Valley region it is known from as far as Nugent, Mississippi, and 

 northward to St. Louis, INIissouri, and Morristown, Tennessee. 



Specimens Examined: In addition to a large series previously recorded, 

 we here record 184 specimens; 110 males, 58 females, 6 immature males and 

 10 immature females.
