This species is especially an inhabitant of swamps. It is found in 

 great numbers in tho.se that border the large erecUs iind rivers of the 

 Atlantic coast, and is comparatively lare inland, where it gives place 

 to other species. With the Acris (jryllus, it is the first si)ecies heard in 

 spring, and although its voice is not loud, the iu)i.se produced b_\ thou- 

 sands of them is deafening when heard (tlose at hand, and is transmitted 

 through the atmosphere for many miles. It may be imitated by the sylla- 

 bles " chock, chock, chock." As a harbinger of spring it is always wel- 

 come.
