brown stripe narrowly edged with whitish, especially on the fastigium; 

 tegmina reddish-brown; dorsum of abdomen with a dark brown band, 

 darker where it meets the green on sides; cerci and ovipositor dark brown. 

 Fastigium not at all ascending, its sides diverging, broadly rounded, its 

 greatest width more than one-third the interocular space. Pronotum not 

 at all sellate; lateral lobes deeper than long, their front and lower mar- 

 gins straight, their angle broadly obtusely rounded, the lower hind angle 

 broadly rounded; humeral sinus evident but very shallow. Tegmina about 

 half the length of abdomen, male, one-third its length, very short and pad- 

 like, female, their tips broadly rounded; in the very rare long-winged form 

 almost reaching the hind knees and exceeded by wings 4 mm. Hind fe- 

 mora unarmed beneath. Cerci as in key and Fig. 188, j. Ovipositor 

 straight, very slender, longer than the body (Fig. 189, If.) Length of body,

dry upland meadows, open pastures and prairies, and reaches ma- 

 turity about August 1st. The mature females are usually much 

 more abundant than the males and vary much in size. It is an 

 active leaper and tumbler and like several of its allies, often 

 strives to escape detection by burrowing beneath fallen weeds 

 and grasses. About Lafayette Fox (1915) found it "abundant 

 h, dry open grass land and a common associate of tiyrlmla inhnir- 

 (il>lUs (Uhler). Adults were taken July 31, were common until 

 Sept. 5, but by October 3 had become very scarce." The long- 

 winged form is everywhere very scarce, only one female from A^igo 

 County having been noted in Indiana, while R. & H. report only 

 eleven in more than 500 adults examined. The species is the 

 largest of the genus occurring in the United States and the range 

 in the length of the ovipositor is greater than in any other, being 

 over 14 mm. 



The types of Scudder were from Dallas, Texas, but it is known 

 from Stateu Island, X. Y., north and west to western South Da- 

 kota and Nebraska and south and southwest to North Carolina, 

 Oklahoma, Texas and Arizona. Mead ( 11104 ) reported it as com- 

 mon in central and northern Ohio, but in Michigan it is known 

 only from Washtenaw County. In Virginia Fox (1917) found it
