Name
The Type Locality of A. julia browningi is City Creek Canyon, Salt Lake County, Utah; Skinner.   In both sexes, the dark markings are reduced or washed out as compared to A. julia stella.  The background color is off white with some yellowish tint which can be even more pronounced in some Cache County populations.  This subspecies is recognized by some as being a race of A. sara.  (The entire complex is under study by Stout.)  However, consistent larval differences between this subspecies, stella, and flora in contrast with sara and thoosa, likely will place browningi under the umbrella of julia.
