 evidently.

This is very common and wide-spread, and everybody knows it 

 if they know any of the smaller butterflies. 



The larval food-plant is Polygonum aviculare, common "knot- 

 grass."

 Dorcas I consider to be a far northern variety or form of 

 Helloides ; smaller, and much darker, as becomes it in that north- 

 ern habitat, but all the ear-marks show it to be the same thing. 

 It is rather common about Sitka, especially out near the lake that 

 supplied the old Russian saw-mill with water ; there it was seen 

 flitting about over the deep moss that covered the meadow, but it 

 was difficult to see or to take, because so dusky, and so concolorous 

 with the moss. 



351. Chrysophanus Cupreus. Not illustrated elsewhere ac- 

 cessibly.

 This gorgeous little butterfly is quite a rare thing ; it is noted 



in the books as taken only in two localities, at Mt. Shasta, and in 

 Oregon. I never saw it at Shasta, although I have hunted there a 

 good deal ; indeed, I have taken only three or four anywhere.
