Tettigidea lateralis polymorpha Burmeister. 

 Arkansas: Ashdown; DeQueen; Mena; Ola. 

 Indian Territory: Howe; South McAlester. 



This species, with Paratettix cucullatus and Neotettix femoratus, 

 is one of the dominant Tettiginae of the Southern States, occurring in 

 countless numbers in wet bottomlands, along streams, and even at 

 considerable elevations about springs, as on Magazine Mountain, 

 Arkansas. The short- winged examples, usually referred to var. poly- 

 morpha, were much less plentiful than long-winged, and the males 

 seem to greatly outnumber the other sex ; this, however, is very likely 

 due to the greater sluggishness of the latter, rendering them less liable 

 to capture in the sweeping-net. 



The frontispiece shows a station where this species was extremely 

 abundant. 



TRYXALINAE. 

 Tryxalis brevicornis Linne. 



Alabama: Tuscaloosa. 



Louisiana: Franklin, Milneburg (juv. 4, 5). 



Locally common in wet meadows, swamps, and along streams. 

 At Tuscaloosa it was plentiful among peppermint in a springy area. 



Mermiria alacris Scudder. 



(Mermiria vigilans Scudder appears to be a synonym of this species). 



Indian Territory: Wilburton (juv. 5). 

 Oklahoma: Shawnee. 



Only half a dozen examples of this species were secured. These 

 include male, female, and immature specimens and were taken among 

 coarse grasses in the vicinity of a stream, and in a prairie meadow.
