" Similar to M. tribulus, but with the digits of the furcula much 

 wider and longer, flattened, from enlarged bases, in length equaling 

 or exceeding the middle breadth of the cerci; the cerci narrower in 

 the middle."

 Texas: Quanah ; Wichita Falls. 



"A rather small, inconspicuous species, long-winged, flavescent 

 brown in color, with unspotted tegmina, faintly barred hind femora, 

 and very pale yellowish-green hind tibiae. Fuscous stripe of the lateral 

 lobes of the pronotum restricted to the prozona, brownish, sometimes 

 obsolete. Subgenital plate of the male seen from above smoothly 

 rounded posteriorly, its ventral outline from the side smoothly convex, 

 terminating posteriorly in an upwardly directed, acute, subapical 

 tubercle, the lateral margins anipliate at base. Last dorsal segment 

 of abdomen of male emarginate at origin of furcula, the latter con- 

 sisting of a pair of short, triangular, flattened processes from expanded 

 bases on the segment, scarcely as long as the segment, parallel, and 

 widely separated. Cerci short, but little longer than their basal width, 

 wide and very stout at base, tapering rapidly, the apical half subequal, 

 tapering to a rounded apex, bent strongly upward and inward, the 

 apex flattened and a little reflexed. Tegmina a little surpassing (male) 

 or about reaching (female) the hind knees. 



"Body: male, 18-22; female, 19-27. Tegmina: male, 14-18; 

 female, 16-19. Hind femora : male, 11-12; female, 13-15 mm." 



Phoetaliotes nebrascensis Thomas. 



Indian Territory: Caddo ; Wilburton. 



Texas: Amarillo ; Clarendon. 



Oklahoma: Cache; base of Mount Sheridan. 



A common campestrian species among the dense grass of the 

 plains and prairies. The young are often largely dull ivory-white in 

 color and present a very singular appearance with their absurdly large 

 heads. It matures late; the young in various stages were met with 

 at Caddo on August 8, and were still plentiful at Wilburton three 

 weeks later. 



Paroxya atlantica Scudder. 



Mississippi: Biloxi (juv. 4, 5) ; Gulfport (juv. 5) ; Nugent (juv. 3, 4, 5). 

 Common in the piney- woods of the Gulf Strip of the Coastal Plain, 

 especially in grassy places among the iukberry or myrtle shrubbery 

 (Ilex glabra), and also in swampy spots and sometimes in the salt- 

 marshes (pi. 2, fig. 2).
