 Ariane is the most abundant Satyrid of the Coast ; it is espe- 

 cially abundant on the lower slopes of the high mountains, where it 

 flies in countless millions, on the mountains of Northern Califor- 

 nia, Oregon and Washington, as well as to the east, in Idaho and 

 Montana. It is also said to be abundant in all the northern States 

 of the Mississippi Valley. 



254. Satyrus Baroni.

 Baroni is very dense, smoky black on upper side, and dark on 



underside, yet all the markings are distinct. Baroni was taken in 

 Northern California, by O. T. Baron, for whom it was named, 

 about 1879. This species is one of the Ariane group, but the 

 yellow halo about the ocelli of the fore wings is absent. 



255. Satyrus Incana. Not elsewhere illustrated.

 This is a rare butterfly, not often taken, and heretofore only 

 known from Washington ; but this second figure is from a speci- 

 men taken in the desert region of Northeastern California, a very 

 different environment from that of the damp, fertile lowland about 

 Puget Sound, where Incana is usually found. Incana is a mem- 

 ber of the Ariane group, and is separated by the whitish outer part 

 of the hind wing on the under side.
