Boopedon auriventris McNeill. 



Arkansas: Magazine Mountain; Mena. 

 Indian Territory: Caddo; Haileyville. 

 Texas: Denison. 



This is an interesting sylvan species peculiar to the southern half 

 of the forested region between the Mississippi River and the Great 

 Plains. It was first met with at Mena, on the eastern slope of the 

 foothills of Rich Mountain, in an open forest of pine and deciduous 

 trees (pi. 3, fig. 2); at Haileyville and Caddo Hill in similar rocky, 

 deciduous woodlands. At Magazine Mountain it was one of the nota- 

 ble assemblage of species which had gathered in the shrubby growth 

 at the edge of the summit cliff (pi. 4, fig. 2). It is of sluggish dispo- 

 sition, and but few are seen, but when aroused it leaps powerfully, 

 often two or three times in succession. In all, eleven males and ten 

 females were captured. The males appear ridiculously small beside 

 their huge mates, 



Boopedon nubilum Say. 

 Texas: Wichita Falls. 



Two specimens were captured among the herbage at the roadside 

 shown in plate 5, fig. i. 



Ageneotcttix deorum Scudder. 

 Indian Territory: Caddo. 



Texas: Amarillo; Bonita; Clarendon; Denison; Quanah; St. Jo; Wichita 

 Falls. 



This is a widely distributed species, locally common, especially 

 on sandy soil with a sparse clothing of herbage, but also occurring 

 frequently among the grass of arid localities. At Caddo Hill it was 

 found on a sandy area of limited extent in the midst of an open wood- 

 land, this relation probably being due to the encroachment of the 

 forests on earlier unforested territory. 



The specimens taken are of large size, with relatively long tegmina 

 and obtuse-angled vertex. 



Aulocara femoratum Scudder. 

 Texas: Quanah. 



Half a dozen examples of this species were secured among the 

 grass in the vicinity of the stony hill-top shown in plate 6, fig. i. 



Aulocara elliotti Thomas. 

 Oklahoma: Cache; Snyder. 



Campestrian, among the mesquite grass of the fields. Two 

 examples only.
