In Indiana the "Lance-tailed Grasehopper" has, up to the present, been 

 recorded only in Vigo county where it is common about the margins of 

 two large ponds in the Wabash river bottoms, but is found nowhere else. 

 The distance between these two ponds is 15 miles and the one to the south 

 is surrounded on all sides with heavy timber. About its margins on Sep- 

 tember 5th, 1892, mature specimens of X attenuatum were very plentiful
