418 ENTOMOLOGICAL NEWS. [April, 



Alaska. The solitary specimen taken by Mr. Young happens 

 to be a female in excellent, in fact, perfect condition. The 

 female does not differ from the male in the disposition of the 

 markings on both sides of the wings, but they are all much 

 heavier, especially on the under side of the secondaries, where 

 the veins are all heavily bordered on each side by grayish 

 green. The species, as has already been pointed out by Ed- 

 wards, is near to P. callidicc Hsper, but quite distinct.

 34 C. hecla Lef. 



There are two female specimens which I refer to this species, 

 agreeing fairly well with specimens I have under this name 

 from Greenland. 



35. C. chione Curtis (?) 



There is a solitary orange yellow specimen in the collection 

 which corresponds almost exactly, with the figure of C. cl/io/u- 

 given by Curtis in the appendix to Ross' Expedition. In the 

 absence of more material I cannot be quite positive as to the 

 correctness of the determination. 



36. C. chippewa Edwards. 



There are twelve males and four females agreeing exactly 

 with the types of C. chippewa in the Edwards collection and
