(Fig. 428) 

 Argyroploce sordidana McDunnotjgh, Can. Ent., vol. 54, 1922, p. 43. 



In genitalia close to constellatana Zeller. In pattern and general 

 liabitus resembling some of the smaller specimens of galaxana and 

 ■constellatana .^ but much darker, above and beneath, and more brown- 

 ish than either. So far represented only by the type material in the 

 Canadian National and Barnes Collections. 



Male genitalia figured from paratype in collection Barnes. 



Alar expanse. — 16 mm. 



Type. — In Canadian National Collection. 



Type locality. — Coliseum Mountain, Nordegg, Alberta.

There are no real differences in genitalia, color, or pattern be- 

 tween Kearfott's supposed two species. In size the more easterly 

 form {glitranana) averages smaller than specimens from British 

 Columbia; but in Manitoba and Vancouver Island there are inter- 

 grades, so the forms can not be distinguished even as races. 



Male and female genitalia figured from specimens in National 

 Collection from Victoria, British Columbia (male paratype of ga- 

 laxana), and Regina, Saskatchewan (female paratype glitranana). 



Bursa of female with signum developed as a scobinate patch with 

 a small central spine. 



Distribution. — Colorado, Saskatchewan, Manitoba, Alberta, Brit- 

 ish Columbia, Vancouver, Alaska. 



Alar expanse. — 16-23 mm. 



Types. — In American Museum. 



Type localities. — Vernon, British Columbia {galaxana) \ Re- 

 gina, Saskatchewan {glitranana).
