There is an authentic male of groenlandicana from Greenland in 

 the Barnes collection, received from Bang-Haas. It agrees with 

 Fernald's type of Tnengelana. Superficially it is much like the 

 A'phania of the tertiana-afjicticm group; but is structurally quite 

 different and a good Olethreutes. The Barnes collection also has 

 two other males and a female, all from Greenland. 



The male genitalia of this Band-Haas type is figured. Female 

 genitalia figured from specimen in National Collection, also from 

 Greenland. 



Aside from the above (and the Fernald types), I have seen one 

 other example, in poor condition, in the American Museum. The 

 other specimens Kearfott had under the name are glaciana. 



Alar expanse. — 16-20 mm. 



Types. — In National Collection {niengelanxx) ; collection Staud- 

 inger {groenlandicana). 



Type locality. — Greenland.

This species fits rather badly in the genus. In many ways — 

 especially on characters of the male genitalia — it fits better in 

 Hedia; but the absence of signa in the female bursa seems to forbid 

 such reference. Veins 8 and 9 of fore wing are more widely sepa- 

 rated, 2 is more bent than in other Olethreutes, and the spining on
