This species exhibits an enormous range of color variation, vary- 

 ing from an extreme rusty form with a bluish cast to the tegmina, 

 to a dull bluish-black form with an ashy suffusion on the head. 

 Some specimens have the hind femora, wings and pronotum with 

 strong maculations, while others are almost immaculate. 



When at rest on the Larrea and mesquite plains this species is 

 very hard to detect, and is frequently unnoticed until it is almost 

 trampled under foot. The habitat of this species appears to be a 

 purely desert one.
