OKTHOPTEEA OF INDIANA. 



263 





As noted above, this is a species of northern range. It has been 

 taken in Indiana but once, near Bass Lake, Starke County, on Au- 

 gust 21, 1902. Here a half 

 dozen specimens, all that could 

 be found during a two-hours' 

 search, were secured from a 

 low, marshy tract, on which 

 the grass had been cropped 

 short. When flushed, the males 

 flew noiselessly 30 to 50 feet, 

 then dropped down and squat- 

 ted low between the grass 

 blades. The single female was 

 more clumsy and did not take 

 to wing; all were found within 

 an area of 100 square feet. 

 It is probable that the species 

 occurs in isolated localities 

 throughout the northern third 

 of the State. In New Eng- 

 land Morse says that it be- 

 gins to mature about July 

 1st, and may be found during 

 the rest of the season. "It is extremely common, even abundant 

 locally, throughout the northern part of New England, being prob- 

 ably the most numerous in point of individuals of any of our Oedi- 

 podince. It is found in dry grassy pastures and other untilled lands, 

 preferably on high ground. Its flight is silent or slightly rustling, 

 usually low, short and direct, resembling that of a large Melanoplus; 

 when with the wind, however, it is occasionally prolonged for several 

 rods in a straight line."
