372 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERa) 



treated in the present paper; the latero-caudal projections of the 

 supra-anal plate of the male are also most decided. The stridu- 

 lating field of the male tegmen is large and very broad ; the stridu- 

 lating vein is very long and evenly but not strongly swollen, with 

 accompanying veins well marked; the veinlets of this field are 

 rather decided. The ovipositor is somewhat broader than usual 

 and more noticeably curved upward.'^ 



This species agrees with 7iebrascensis in having 

 the ventrocephalic margins of the cephalic and 

 median femora usually but not always armed with 

 a few small spines, and the ventral margins of 

 the caudal femora with a number of irregularly 

 spaced short delicate spines. 



Types. — Described from two males from a 

 single localit3^ 



Single Type here Designated: 6^ ; Staten Island, 

 New York. (Wm. T. Davis; in cat-tails on salt 

 marsh.) [Davis Collection.] 



The material before us shows that there is a 

 great amount of individual variation in the 

 species, what geographic variation exists can not 

 be definitely ascertained as the species is yet 

 known only from single records over apparenth^ 

 the greater part of its range. 



The spines of the cephalic and median tibiae are rather short 

 and heavy; the ventral margins of the caudal femora are armed 

 with numerous short delicate spines, normally internal 5-9, exter- 

 nal 4-8, often specimens may be found with several more 

 extremes before us; internal 5-11, external 4-10. 



The green color phase is the more abundant, but very fre- 

 quently specimens are brown in general coloration.

8 Immature females of the present species have the ovipositor curving 

 weakly downward. In the early stages apparently no trace of black mark- 

 ing on the vertex or margins of caudal femora is ever present; in species 

 having the vertex decidedly produced, such production is decidedly less.
