Grasshoppers of Kansas. 121 



usually rather faint and more distinct on either margin than in the 

 middle. Wings broad, one and three-quarters times as long as broad, 

 with the apex not attenuate; fuscous band moderately broad, at least a 

 sixth as wide as the length of the wing and very distinct, continued along 

 the posterior margin more than half way to the anal angle; spur short, 

 extending toward the base about one-third of the distance. Posterior 

 femora unusually heavy, with the inside yellow, more or less suffused 

 with red, and crossed by three black bands, the basal sometimes much re- 

 duced; outer side crossed transversely by one distinct subapical band, a 

 continuation of the one on the inner surface; lower sulcus red, crossed 

 by the same subapical band. Posterior tibiae bright red, with an in- 

 definite subbasal yellow cloud on the outer face only. 



Length of body, male 21 to 26 mm., female 23 mm.; length of tegmina, 

 21.5 to 25 mm., female 22 mm.; length of posterior femora, male 11 to 13 

 mm., female 13 mm.

Brownish cinereous, the vertex darker than the rest of the head, all 

 the sculpturing of the head sharply defined; antenna? yellowish brown, 

 deepening apically. Posterior half of anterior lobe of pronotum rather 

 strongly corrugated, the median transverse sulcus very deeply impressed; 

 surface of anterior lobe otherwise smooth, posterior lobe delicately but 

 distinctly rugulose; median carina rather prominent and heavy on an- 

 terior lobe, slight but sharply defined and posteriorly obsolescent on pos- 

 terior lobe. Tegmina marked with two obscure, narrow transverse belts 

 of dark fuscous flecks, one in the middle and one beyond the basal fourth; 

 a similar but faint third band appears before the base of the apical 

 fourth, and beyond it a few obscure quadrate fuscous flecks in the 

 diaphanous part of the tegmina, caused by the infumation of single cells 

 and the nigrescence of their bordering veins. Wings very pale yellow- 

 ish or milky, with a diaphanous tip, on which the veins are black and 

 the cross-veins yellowish or partly yellowish and black, and with an un- 

 usually broad, very dark, almost piceous middle band, occupying about 

 one-third the length of the wing on the middle of the costal margin, and 

 curving around to the inner angle; its outer border straight or even 

 slightly concave until just before it reaches the outer margin, which it 

 avoids by bending in a short distance; the inner border of the band is 

 strongly and pretty regularly arcuate, scarcely tending toward the base 

 above. Hind femora with faint traces of a pair of dusky transverse 

 bands on the outer face; hind tibia? pale reddish, with black-tipped spines. 



Length of body, 29 mm.; of antenna?, 11.5 mm.; of pronotum, 6 mm.; 

 of tegmina, 32 mm.; of hind tibia?, 12 mm. 



This species seems to be limited to the western portion of the state.
