 confined to the disk. Some specimens have a light testace-

 middle of the occiput and pronotum to the tips of the teg-

 spots ; hind tibiae bright coral red with a whitish basal an- 

 nulus, the knee black; antennas ferruginous, testaceous or 



lavender usualh^ the latter in living

mon, but is found among the grass 

 in our prairies. It prefers sandy spots, upon which it will 

 settle very closely, evidenth^ protected in this manner by its 

 similarity of color to such surroundings. It leaps vigorously 

 for several times in succession, and without noise. It is 

 found from middle of July to early October. 



SUB-FAMILY. 



[CBdipodinse.) 



This sub-family includes two tribes, the CEdipodini and 

 Eremohiini, but as no insects belonging to the latter occur 

 in Minnesota it is not necessary to give its distinguishing 

 characters, which have alread\% in part, been given in the 

 classification. 



CBdipodinse include genera in which the head is rounded 

 at the union of the vertex and front, and in which the front 

 is perpendicular or nearly so. The antennae are linear or 

 sub-linear, and usually inserted nearer the mouth than the 

 middle of the eyes; sometimes the^^ are inserted just in front 

 ofthee\'es, which are small or of medium size, and really 

 longer than that part of the cheeks below the eyes. In the 

 typical forms the posterior lobe of the pronotum is longer
