This is probably the most common of the large cicadas found 

 in Mississippi, and has been reported from all parts of the state. 

 Eighty-one specimens have been examined, and the dates of cap- 

 ture are from June to September, but it will also be found in Oc- 

 tober. The localities from which these speimens came arranged 

 from north to south are : Nesbitt, Kossuth, Corinth, Coldwater, Blue 

 Mountain, Sledge, Ratliff, Charleston, Houlka, Pace, Buena Vista, 

 Cleveland, O'Reilly, Pheba, Greenville, Leiand, Winona, Vaiden, 

 Long View, Sturgis, Agricultural College, Columbus, McCool, Good- 

 man, DeKalb, Ferns Springs, Flora, Jackson, Forkville, Lake, Vim- 

 ville, Montrose, Fayette, Ellisville, Columbia, Hattiesburg, McComb, 

 Picayune, Anner and Kiln. 



This species is distributed over most of the eastern half of the 

 United States from eastern Texas and Kansas northward to Michigan 

 and New York. We have collected it as far south as the Caloosa- 

 hatchee River, Florida. The variety australis Davis, which is much 

 greener colored, occurs not uncommonly in parts of Florida and 

 Georgia, and should be found in Mississippi. 



The song of this species is more impetuous than that of most of 

 the related species, rising to a rapid ^ing and then gradually sub- 

 siding. 



Tibicen resonans (Walker).
