Grasshoppers of Kansas.

Hind femora ash gray, with two or three faint, ill-defined, slightly ob- 

 lique fuscous bands. Hind tiba? yellow, the spines black tipped. 



Length (of an average specimen), male 19 mm., female 28 mm.; of 

 antenna?, male 8 mm., female 9.75 mm.; of tegmina, male 24 mm., female 

 30 mm.; of hind femora, male 11 mm., female 13.5 mm. 



Six males and nine females. Gaudalupe Islands, off Lower California 

 (E. Palmer); San Diego, Cal. (H. Edwards, No. 9); Mexico (Coll. 

 Schaum). 



This is our only species with lemon-yellow tibiae; therefore there will 

 be no trouble in separating it from the other T rimer otropis. The color- 

 ing of the species is quite fantastic, often being a complete reproduction 

 of the variegated color of the lichen-colored rocks upon which it lives. It 

 is needless to say that the protective coloration is most striking.

This very large and striking new species is allied to T. tolieca and 

 pistrinaria Saussure, but differs from both in the very much greater size, 

 and from tolteca in the presence of a hyaline distal section on the wings, 

 as well as from pistrinaria in the practical absence of the usual ulnar 

 spur on the wing. 



Size very large (for the genus) ; form moderately robust. Head with 

 the occiput rounded and slightly elevated above the level of the disk of 

 the pronotum, interspace between the eyes as broad as the greatest width 

 of the disk of the f astigium ; f astigium considerably declivent, the slope 

 of the same being a regular continuation of the arch of the occiput, 

 lateral carinas of the fastigium parallel caudad, regularly approaching 

 one another cephalad, median carina faintly indicated caudad; lateral 

 foveola? undefined, no ventral bounding ridge in the usual position; 

 frontal costa considerably constricted dorsad, broader and subequal for a 

 distance dorsad and ventrad of the ocellus, on the ventral portion of the 

 face the costal carina? expand in an undulating fashion, sulcation distinct 

 but not very deep, in fact shallow in the constricted dorsal portion; eyes 

 not prominent, somewhat shorter than the infraocular sulcus; antenna?
