Plwxopteris suhaequana Zeller, Verh. Zool.-bot. Ges. Wien, vol. 25, 1875, 



p. 254. 

 Ancylis subaequana Febnald, in Dyar List N. Amer. Lepid., no. 5241, 1903. — , 



Barnes and McDunnough, Check List Lepid. Bor. Amer., no. 7175, 1917. 



Zeller described this species from three specimens, two males and 

 one female. The males are probably in the British Museum and one 

 of these must be considered the actual type. The female is now in 

 the Fernald Collection. It is much smaller than typical specimens 

 of suhaeqitana and is very likely not that species. It has more the 

 size and appearance of one of the angulifasciana group. However 

 that may be, it need cause no great difficulty, as the true suhaeqitana 

 is quite distinct from other species in this genus. Its extremely 

 long, slender aedoeagus at once identifies it. 



Male genitalia figured from specimen in National Collection from 

 Sabec Lake, Maine ("June 25-30"). 



Distribution according to specimens in National Collection, Amer- 

 ican Museum, and collect on Barnes : North Carolina, Virginia,

3. ANCHYLOPERA SUBAEQUANA KINCAIDIANA (Femald). 



Phoxopteris kincaidiaim Feknald, Proc. Wash. Acad. Sci., vol. 2, 1900, p. 500. 



Ancylis Mncaidiana Febnald, in Dyar List N. Amer. Lepid., no. 5627, 1903. — 



Baknes and McDunnough, Check List Lepid. Bor. Amer., no. 7204, 1917. 



Described as a distinct species but has the same genitalia as sub- 

 aequana. It differs in having a sordid ochreous rather than a cream 

 white head. The costal and outer areas of the wing also have the 

 white ground color more suffused and obscured by grayish dusting 

 than typical specimens of subaequana., but these characters are by 

 no means constant. I am holding it therefore as nothing but a 

 northwestern race of Zeller's species. 



Distribution according to specimens in National Collection, Amer- 

 ican Musemn, and collection Barnes : Alaska, British Columbia. 



Alar expanse. — 15-17 mm. 



Type. — In National Collection. 



Type locality. — Metlakahtla, Alaska. 



Food plant. — ^Unknown. '
