 p..?. (1873.) 



' ' Size and aspect of C. muliifaria. 



" Head, collar and patagia bright crimson, the latter narrowly edged

 article black. Antennae long, blueish black, closely bipectinate. Tho- 

 rax with the disc greenish black. Abdomen very glossy, blueish black, 

 with a faint greenish tinge. Legs blueish black, with the anterior 

 C0X3S distinctly white. Fore tibiae with a few white scales. 



"Primaries blueish black, with a greenish tinge, most vivid toward 

 the base. Costal edge entirely dull black. Fringe white at apices, 

 the remainder black. 



"Secondaries, blueish black, with a purple tinge. Fringe white at 

 apices, rest entirely black. 



'■^Expanse of wings 1.90 inches ; length of body, 0.60 inch. 



"Habitat. — Fort Crook, Oregon, June, 1872. (Coll. H. Edwards.) 



"I owe the possession of this beautiful specimen to Lord Walsing- 

 ham, who found it in the above locality during his recent tour through 

 Southern Oregon, where it appears to be very rare. At first sight, this 

 species may be confounded with C. muliifaria, but differs in having 

 the costa entirely black, and the apices of the wings only with white 

 fringes." H. Edwards, (loc. cit.)
