 This is a species with the body rather slender, of more than average 

 length ; constant in color but dimorphic as respects the length of wings, 

 the long winged forms, however, being very scarce. Sides of head and 

 body together with all the femora green. The usual reddish brown stripes 

 on occiput and pronotum narrowly edged with whitish, especially on the 

 fastigium of the vertex. Tegmina reddish brown ; in the females exceed- 

 ingly short and pad like, or well developed and reaching almost to knees ; 

 when the former, a little longer than the wings ; when the latter, 5 mm. 

 shorter than the wings. In the brachypterous males (the only ones I have 

 seen ) the tegmina are somewhat less than half the length of the abdomen. 

 A reddish brown band on dorsal surface of abdomen, darker where it 

 meets the green on sides. < >vipositor pale red, straight, one and a half 

 times the length of the posterior femora. Cerci of male, long, the apical 

 half acuminate, curved slightly inward near the tip. 



Measurements : Male — Length of body, 14 mm.; of tegmina, o.o mm.; 

 of pronotum, 3.5 mm.; of hind femora, 13.5 mm. Female — Length of body, 

 1 7 mm.; of tegmina, short winded form, 3.5 mm.; long winged form, 16 mm.; 

 of hind femora, 15.5 mm.; of ovipositor, 23 mm. 



A common species in the prairie country of the western and northern 

 parts of the state, where it frequents, for the most part, dry upland mead-

 leaper and tumbler and, like the next species, often striving to escape de-
