REHN AND HEBARD 377 



The armament of the hmbs is rather similar to that of exilis- 

 canorus; the ventral margins of the caudal femora are armed with 

 short delicate spines, the extremes in the few specimens before 

 us are, internal 7-12, external 4-6. 



All of the material before us is of the green color phase. 



McNeill states that the song of this species is continuous and 

 that the insect begins singing earlier in the evening than does 

 ensiger. 



The species is known from Ohio and Sarnia, Ontario, west to 

 Minnesota, extreme eastern Nebraska and northeastern Kansas, 

 south to St. Louis, Missouri. 



In addition to one specimen examined l)y us but previously 

 correctly recorded, we here record the following 7 specimens; 5 

 males and 2 females, of which the typical material has been pre- 

 viously recorded as from "eastern Nebraska and -Illinois."

The present insect is more nearly related to N. lyristes than 

 to any other known species, diiTering, however, in the much shorter 

 vertex, decidedly less elongate form, proportionately shorter caudal 

 femora, and notably in the female sex in the similarly rather wide 

 but much shorter ovipositor which is very weakly curved down- 

 ward. The stridulating field of the male tegmen is similar to 

 that of lyristes ])ut somewhat -l^roader, with veinlets of this field 

 slightly more pronounced. 



This species is now known to be very abundant and widely 

 distributed in the areas of Spartina patens on the tidal marshes of 

 the New Jersey coast. The large series before us agrees perfectly 

 with the type except in size, which is decidedly less in these 

 northern examples. The type has the ventral surface of the 



TRAN.S. AM. E\T. .SOC, XL.
