metazone is obtusely but sharply angulate. The lateral lobes of the 

 pronotum are higher than long with the anterior and posterior margins 

 straight, decidedly and equally oblique, and with the lower margin 

 strongly arcuate and Somewhat angulate in the middle. The lobes of 

 the mesosternum are separated by a space much wider than long, the 

 metasternal lobes by a linear ridge with an elongate deep pit on either 

 side. The wings and tegmina are well developed but do not exceed 

 the abdomen. The former in the male have the scapular area consid- 

 erably expanded and filled with strong oblique cross-veins. The dis- 

 coidal area is filled with irregularly reticulating veins. The posterior 

 femora are banded on the inner and outer surfaces. The posterior 

 tibiae have the apical spurs on the inner side very long and stout, be- 

 ing twice as long as those on the outer side, and the anterior one of 

 the inner spurs is nearly twice as long as the other. The valves of 

 the ovipositor are only moderately exerted. 



This genus is North American and is represented by two species 

 only, both western forms.
