others two lines partially divided by dark scaling, and still others 

 "with the normal two lines so completely broken as to make four. If 

 the names were ke]3t separate it would be impossible to decide under 

 which many specimens would go. In fact, the Kearfott paratype 

 of placerana in the National Collection has four distinct white marks 

 and agrees more closely with his type of lana than with any of the 

 other types of placerana. There are some differences in the size 

 and shape of the harpes of the male genitalia between the actual 

 types of flacerana and Vancouver ana; but in a series of moths from 

 Goldstream, British Columbia, all collected upon the same day 

 (June 1, 1921) the intergrades are such that it is impossible to tell 

 under which name some of the specimens should go if the two 

 names are to be kept separate. The species is probably a stem borer 

 or seed-capsule feeder, which habit would easily account for the 

 variability. A reared series of S. tristrigana shows quite as much 

 variation. I am of the opinion that lana is only a race of edtvards- 

 iana, from which it differs chiefly in the darker cilia of its hind 

 wing, not a good character. This synonym, however, will have to 

 wait upon rearings before it can be definitely settled. 



Hind wing with veins 3 and 4 connate.

Females of this species average somewhat larger than lana and 

 show some slight differences in genitalia, having the chitinization 

 about genital opening much weaker. It is probable that the two 

 are only racially distinct. The determination of this, hoAvever, will 

 have to wait upon rearings.
