OF NORTH AMERICA. 31 



Anterior wings, clear pale brown, with the veins and all the mar- 

 gins of the wings blackish, and a few steel blue scales at the base. 

 Extreme costa and fringes, white, interrupted with dusky about the 

 middle of the outer margin. Posterior wings, velvety black, with 

 metallic blue reflection^; fringes, white, interrupted near the anal and 

 apical angles with blackish. Beneath, as above, except that the 

 anterior wings have a deeper tint, and the posterior wings are browner 

 than above.

Habitat. — -California. [Coll. Behr, H. Edwards and Stretch.] 



This fine species was taken by Dr. Behr, of San Francisco, in Marin 

 County, California, on the slopes of Mount Tamalpais, and I am 

 indebted to him for the specimen in my collection. While more 

 allied to C. Multifaria and C. Ochroscapus, than the other members of 

 the genus, it is abundantly distinct from either. It was taken in swampy 

 localities, sitting on the stems of carices, and shows but very little ten- 

 dency to vary in its coloration, as the inspection of some ten specimens 

 proves. This insect is also found on San Miguel Island, off the 

 coast of California, my friend, W. Harford, having taken a number of 

 specimens in that locality.

 originate at the base of the wing, but none of the stripes reach the 

 outer margin. Costa, narrowly edged with yellow on the basal two-
