Form a 



Plate 2 (fig. e) 



Basal part, a little less than half of forewing, white or yellowish 

 with a brown short oblique streak or triangle at dorsum, and black 

 well-developed raised scales on this streak; entire external part of 

 forewing brown or yellowish brown with a slightly darker obliterate 

 costal triangle. Some small groups of black raised scales at border 

 of these two so differently colored areas. Some interrupted blackish 

 transverse (in external part of forewing, oblique) lines crossing both 

 areas. Costa of forewing with gray obliterate lines and minute dots. 

 Hind wing grayish white with slight dark reticulation. 



At first sight, this form may remind one of Acleris variegana 

 (Schiffermiller and Denis). Although all known specimens of this 

 form originate from the State of Washington, it does not represent 

 there a constant subspecies. The nominate form of britamiia is also 

 known from this state. 



Specimens examined, — State of Washington: one male (genitaha 

 on shde 6097, prepared by J.F. Gates Clarke, Nov. 7, 1934), PuyaUup, 

 Pierce County, Aug. 20, 1930 (T. C. Clarke); one male, Toledo, Lewis 

 County, Aug. 5, 1931 (J. F. Gates Clarke); three males (genitalia of 

 one on shde 1-Obr., Feb. 25, 1959), Bonneville, Clark County, July 

 15-16, 1931 (J. F. Gates Clark); all specimens in USNM. 



Form b 



Plate 2 (fig. 5) 



Forewing yellowish brown, with a slightly darker indistinct costal 

 triangle and black raised scales arranged as in former variety. A 

 tuft of whitish raised scales on discocellulars. Some dark transverse 

 Hues well developed in external part of forewing. Hind wing grayish 

 white with gray reticidation. 



Specimen examined. — One female (genitalia on slide, prepared by 

 A. Busck, Oct. 11, 1924), Biological Station, Departure Bay, British

Head, labial palpi, thorax, and forewings whitish ochreous. An- 

 tennae concolorous, with darker annulation. Abdomen pale grayish. 

 Forewings with three parallel oblique ochreous bands almost equally

 second from about middle of costa to two-thirds of dorsum, third
