 This was one of the first butterflies of the West Coast to be 

 named ; it flies in the vicinity of San Francisco Bay, and so early 

 fell into the hands of the French collector during the first gold 

 fever, and sent to France, where it was named by Boisduval. 

 Arota and the next, Virginiensis, are much alike, and will puzzle 

 to separate if the locality labels are missing; I have a good series 

 of both, but find no feature that can be relied on in all cases, as 

 each character seems comparative, only.

 This is a mountain butterfly, seen only at high elevations, except 

 at the north, where northing counts as elevation. The example b 

 above, is the darkest one I have, showing less white on hind wing ; 

 others taken south in California have nearly as much white be- 

 neath as Arota.

No figure. 

 I have never been able to distinguish this species. The descrip- 

 tion is as follows : "Size, about one inch ; sexes much alike ; upper 

 side, pale fulvous ; margin brown ; an irregular row of brown 

 discal spots. Under side, fore wings pale buff, spots large and 

 distinct ; hind wings base grayish, margin clouded gray ; a row of 

 discal black spots ; at anal angle a black spot, and near it others 

 obsolete ; a long, tapering tail."
