A widespread and locally plentiful campestrian species inhabiting 

 by preference moist fields and meadows. At Amarillo red-legged 

 examples were scarcely more numerous than those with pale glaucous 

 or bluish hind tibiae, and similar specimens were common at Fayette- 

 ville. 



Melanoplus flavidus Scudder. 

 Texas: Clarendon. 

 A single pair. Campestrian. 



Melanoplus foedus Scudder. 

 Arkansas: Dardanelle. 

 Texas: Wichita Falls. 

 Oklahoma: Shawnee. 



This species was found among tall weeds and grasses along the 

 banks of streams and flood channels, occurring plentifully in the local- 

 ities named. Specimens vary much in color of hind legs, and appar- 

 ently the species runs into packardi. 



Melanoplus gflaucipes Scudder. 



Texas: Bonita. 



Oklahoma: Mountain Park. 



A sluggish species, living among bunch-grass in arid stations. 



Melanoplus gracilis Bruner. 



Arkansas: Magazine Mountain, 2,400 feet. 



This species was detected but once, in a cool, damp thicket on 

 the heavily shaded northern side of Magazine Mountain, almost within 

 the shadow of the summit escarpment (see p. 18). Here it was not 

 uncommon, but very alert and secretive, seldom showing itself, and 

 quick to leap away. It should be sought in similar stations through- 

 out the forested sections of Arkansas and the neighboring States. 



Melanoplus impigfer Scudder. 

 Texas: Bonita; Clarendon. 

 Oklahoma: Shawnee. 



In the single male obtained at Shawnee the digits of the furcula 

 are exceptionally long, very nearly one-half as long as the supra-anal 

 plate, cylindrical save at base, and diverge in a gentle curve ; in the 

 other specimens secured they are noticeably flattened for half their 

 length and less divergent. The color of the hind tibiae varies from 

 deep blue to cherry-red. 



At Bonita this locust was common in the open forest of oaks and 

 hickories, of which the Upper Cross Timbers is largely made up, and 

 in the open fields as well.
