BUTTERFLIES OF MONTANA. 133 



Under side like the male, but brighter, and with markings more dis- 

 tinct; a fulvous tint is also seen at outer angle of primaries. 



This pretty little species may be distinguished from Xanthoides, its

 and more rounded outer angle of primaries, the blunter tooth of second-

Early Stages Unknown. 



Distribution The species is recorded from Montana and Nevada. In
