HAB. Sonorau Region. 



A single specimen obtained in 1872 in Middle Utah. In 1873 and 1874, 

 the species was found to be quite numerous in Colorado, Arizona, and New 

 Mexico, frequenting rocky places, and exceedingly hard to catch. Color of 

 throat yellowish-orange, of abdomen Avhite ranging to greenish-olive. 

 The general coloration depends much upon the color o'f the rock upon which 

 they are found. 



The specimens marked XXX and XXX 1 are apparently very closely 

 allied to U. stansburiana, B. & G., but vary in some points and may prove 

 to be a new species, or a variety of the one they resemble.
