This subspecies is quite variable and possibly should be subdivided. 

 Specimens from more southern localities tend to have more extensive 

 white marldngs; those from the Rocky Mountain area tend to be 

 largely fulvous in ground color; and those from British Columbia, 

 Oregon, and New Mexico tend to have the fuscous at apex of hind 

 femur reduced, sometimes practically lacking.
