400 STUDIKS IN AMERICAN TETTIGONIIDAE (oRTHOPTERA) 



In the female sex the green color form is strongly predominant, 

 but in the series of males before us brown individuals are some- 

 what the more numerous. In the brown phase the variation is 

 decided, extreme individuals are; of pale general coloration, naples 

 yellow; of dark general coloration, mummy brown. 



The males of the present species were found to be at night very 

 alert and shy, in New Jersey much the most difficult of the species 

 to take excepting N. caudelUcmus. The method of escape is, 

 however, to hide with agility in the tangles of vegetation in which 

 the species is usually found, not to seek safety in flight. The song 

 is a continuous dzeeeeeeeeeeeee, very high pitched (higher than 

 that of A^. lyristes or A^. retusus) and very weak (as weak as that of 

 retusus) . 



The series taken at Corn wells, Pennsylvania, was captured 

 during the day bj^ beating the tangled vegetation and particu- 

 larly a small area of Pomcularia septentrionalis in a marshy spot. 

 In the latter plant the females were exceedingly numerous, nearly 

 all being taken there. These specimens showed that in the day- 

 time individuals are sluggish, inoving but slowly about, but the 

 clinging powers were found to be remarkable and the use of the 

 spines on the limbs for this purpose was quickly apparent. 



Probably owing to the very local distribution of the species, it 

 is known from a number of widely separated localities; on the 

 Atlantic coast from New Brunswick, New Jersey, south to Ra- 

 leigh, North Carolina and westward from Vigo County, Indiana, 

 south to New Orleans, Louisiana.
