A. diversilineata Grt. (36 b) is a most variable species. The type has the greyish-white forewing 
rather densely strewn with blackish-brown, the dentate transverse lines bordered with whitish, the small maculae 
in white rings and surrounded with black; instead of the undulate line there are small black sagittae before 
the darkened marginal area. Hindwing whitish, on the veins and margin brownish. — Lighter, less distinctly 
marked specimens are called illepida Grt. (36 b), still lighter specimens with a prominently darkened marginal 
area are resoluta Sm. (36 b), whilst entirely white specimens with intense black markings belong to the form 
submissa 8m. (36 c). Colorado, Utah, New Mexico, California, Arizona. 
A. contacta Wkr. (= aspera Morr ., diffusilis Harv., sansar Streck., extincta 8m.) (36 a, c) is one 
of the largest species, the bluish-grey forewing irrorated with brown, in the marginal area darker, with strongly 
dentate transverse lines bordered with white on the averted sides, the maculae finely encircled with black; 
the distally very strongly dentate subterminal area is defined by light grey towards the darkened marginal 
area. Hindwing greyish-brown. Canada to Washington. ■— The form pulverulenta Sm. (36 c), from Canada, 
is of a purer bluish grey, strewn with black, and the marginal area is not darkened. 
A. pallifera Grt. (36 b) is a lighter species, greyish-white, irrorated with reddish-brown, with double 
crenulate transverse lines, a large brown coniform macula surrounded by black, and large upper maculae. 
Hindwing yellowish greyish brown, at the margin darker. Illinois. According to Benjamin, it may be = Euro- 
type medialis. 
A. ochracea Sm. (36 d). Forewing more yellowish, in the median area somewhat darker, the dentate 
transverse lines single, submedianly connected by a dark streak; the large maculae are laterally marked with 
ochre-yellow, the coniform macula is absent; instead of the undulate line there are yellowish lunulae with black 
sagittae in front of them. Hindwing whitish with an interrupted black marginal line. United States (Iowa). 
Hampson’s figure which we copied is too dark, too contrasting, the hindwing much too dark. 
A. dispar Sm. (36 d) is similar to ochracea , strewn with a darker brownish grey, the anterior transverse 
line is almost entirely absent, before the much smaller ring-macula there is a black angular spot. Hindwing 
of a pure white. Colorado. 
A. olorina Grt. is a very light, black-strewn species with darker veins, single dentate transverse lines, 
the maculae surrounded with black; the black dentate undulate line returns on the folds to the postmedian 
line. The white hindwing is at the base of the fringe strewn with brown. California. 
A. aedon Grt. (36 c). Probably only the Californian representative of theodori without its reddish- 
yellow admixture; darker grey than olorina and probably also only a large subspecies, on the whitish ground 
strewn with dark brown and in some places irrorated with red-brown, with blackened veins, dentate black 
transverse lines and the maculae intensely surrounded with black; the black dentate undulate line is on the 
two folds inwardly crenulate as far as the postmedian line. Hindwing yellowish-white, on the margin darker. 
Washington to Colorado and Nevada. 
A. theodori Grt. (36 d) is the lightest species, almost white with reddish-brown irroration, the veins 
striped blackish, strongly notched transverse lines and the maculae feebly surrounded with red-brown; the 
black notched undulate line extends as in aedon , behind it more intensely irrorated. Hindwing white, feebly 
brownish on the veins and margin. The $ is generally irrorated with a darker colour. — The form vancouvera 
Strd. ( = ab. 1. Hmps.) is a much darker brown form with a red-brown abdomen, and the hindwing uniformly 
suffused with red brown. — epichysis Grt. (36 d) is the southern form of California, much greyer, on the 
forewing extensively irrorated with purple reddish, also on the hindwing. — Canada to California and New 
Mexico. 
A. olga 8m. (36 e) is a much smaller species belonging hereto; forewing white, strewn with black 
and in some places irrorated with rust-brown, particularly at the base, in the distal half of the median area 
and subtenninally, with single sharply dentate black transverse lines and with a very distinct broad faded 
median shadow approximating the postmedian line; the undulate line runs as in the two preceding species, 
anal wards a brown shadow darkens a black streak which is visible from the distal margin to the coniform 
macula; the maculae are surrounded with black and centred with ferruginous brown. Hindwing white, towards 
the margin feebly darkened by smoky brown. From the Sierra Nevada in California. 
A. maxima Dyar (36 d) is the most imposing representative of this group, very near to acera, but 
browner; yellowish red-brown with a black basal ray, the dark notched transverse lines bordered with whitish, 
connected by a black streak prolonged from the pointed coniform macula, the large maculae in whitish rings 
and centred with yellowish; before the light undulate line there are dark sagittae. behind it dark vein-streaks. 
Hindwing yellowish-brown, with somewhat darker veins. California. 
A. acera Sm. (36 e). Forewing purple grey, in the median area tinted with red-brown, with a black 
basal ray and hardly indicated double transverse lines, both being connected by a brown streak from the end 
of the coniform macula; the two upper maculae are large, above open, below often connected. The undulate
