identified at the U. S. National mu . 
seum as Colias chr>somelas and Phy- 
ciodes orseis. These two species have 
not hitherto been known to exist in 
Colorado, and additional specimens 
from this state are much required. 
Another butterfly imperfectly known 
to us is from Riverside, Chaffee county, 
August 16th, 1887. It is a Chryso- 
phanus or “Copper butterfly,” and 
Mr. Henry Edwards, who now has 
the specimen, says it is like Mariposa, 
but is not that, and looks like a new 
species. We have called it C. canyo- 
num, but do not describe it as the 
specimen we sent to Mr. Edwards is 
too imperfect, and we have no other. 
It is peculiar for having brown spots 
bordered with whitish on the under 
side of the hind wings. 
Mr. H. W. Nash, of Pueblo, has 
kindly undertaken to work up the but- 
terflies of Colorado for the C. B. A. 
He will be glad of notes and speci- 
mens from every county, especially 
those in the extreme eastern and west- 
ern parts of the state.
