26 FURTHER RESEARCHES ON NORTH AMERICAN ACRIDIID^. 



This, the most plentiful member of the genus in Austral regions, 

 was taken at a number of localities in small numbers, usually on sandy 

 loam, commonly in company with other members of the group, either 

 Tettix, Neotettix, or Tetligidea. 



Tcttix hancocki Morse. 



Arkansas: Fayetteville (juv.) ; Rich Mountain; Winslow. 

 Widely distributed in the Upper Austral and Transition zones of 

 the central part of the country, generally occurring on moist upland 

 soils of sandy texture, especially on high elevations, 



Tettix omatus Say. 



Alabama: Valley Head. 



Common in a valley pasture of three or four years' standing, and 

 probably not eradicated from it during cultivation (see Paratettix cucul- 

 latus). This and the preceding species are of much more frequent 

 occurrence in the Northern than in the Southern States, their range 

 extending even into the Canadian zone. In the North this species is 

 often associated with Nomotettix cristatus. 



Paratettix CUCullatuS Burmeister. 



Paratettix cucullatus abortus Hancock. 



Alabama: Tuscaloosa. 

 Mississippi: Gulfport. 



Arkansas: Ashdown; Blue Mountain Station; Dardanelle; DeQueen; Fay- 

 etteville ; Magazine Mountain ; Mena ; Ola ; Rich Mountain Station. 

 Indian Territory: Haileyville; Howe; South McAlester; Wewoka. 

 Texas: Bonita; Clarendon; Denison; Wichita Falls. 

 Oklahoma: Cache; Mountain Park; Shawnee; base of Mount Sheridan. 



A very widely distributed and frequently very plentiful species 

 frequenting the shores of ponds and streams, sloughs, springy runs, 

 etc., from southern New England to Texas and Colorado. (See front- 

 ispiece.) At Dardanelle, Arkansas, it was exceedingly abundant in a 

 moist, shallow gully in a cornfield on the sandy bottom-land along 

 the Arkansas River. 



Three specimens of the short- winged form abortus Hancock were 

 secured at Gulfport, Mississippi, at a spring on the edge of the sea- 

 beach. 



Telmatettix aztecus Saussure. 



Oklahoma: base of Mt. Sheridan, Wichita Mountains. 

 A single male of this species was taken in the stony bed of a small 

 stream at the foot of the northern talus slope of Mount Sheridan 

 (pi. 8, fig. 2) hidden in the woods.
