396 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERA) 



Single Type here Designated: d" ; Lakehurst, New Jersey. Sep- 

 tember 1903. (Wm. T. Davis.) [Davis Collection.] 



The armament of the limbs is generally similar to that of ro- 

 bustus; the ventral margins of the caudal femora likewise bear a 

 few small spines, in the series before us the extremes in num- 

 ber being, internal 8-13, external 0-8. 



For measurements see page 397. 



Of the twenty specimens now before us, but three males are 

 of the brown color phase. 



The present insect is not only the least plentiful of the species 

 of the genus found in New Jersey, but is also much the most 

 wary and difficult to capture. It is very widely distributed not 

 only along the coastal strip in truck gardens, waste fields and 

 marshy fresh water areas, but also in boggy portions of the adja- 

 cent pine barrens and in fields there located. The insect was to be 

 heard at intervals everywhere during two evening's collecting be- 

 tween Cape May Court House, and Port Republic, New Jersey, 

 but at no locality were more than three or four widely scattered 

 individuals to be heard at one time. In the pine barrens it was 

 much less often heard, but in one boggy area near Mays Landing, 

 New Jersey, numerous widely scattered individuals were encoun- 

 tered. The song of this species is loud, resonant and constant, 

 dzeeeet-dzeeeet-dzeeeet, always the same, not rising and falling, 

 the notes given deliberately, counted as averaging 12 to 10 sec- 

 onds. The males would continue their loud song fearlessly until 

 approached to within about eight feet, then ceasing abruptly they 

 would almost at once fly into the darkness with a swift power- 

 ful zigzagging flight. In alert swiftness this species and N. velox 

 are distinctive. 



The present species is known only from the type locality, James- 

 burg and Tuckerton, New Jersey, in addition to these given below.
