In 1871, this species was observed to be quite common in Nevada, and 

 a number were secured. In the following year, they were also observed in 

 Utah, and, in 1873 and 1874, were found exceedingly abundant in Arizona 

 and New Mexico, but were hard to catch, running with the greatest celerity 

 over the sand and rocks. It is not at all arboreal in its habits. Dr. Coues 

 mentions that, finding it impossible to capture them in the ordinary manner, 

 he used a small load of shot in a horse-pistol. They can readily be taken 

 with an ordinary butterfly -net.
