0. iricolor 8m. (26 c) has ochreous-whitish forewings irrorated with a reddish hrown, with a faded tricolor. 
silvery bluish band before the anterior transverse line, some more silvery blue spots being situate in the centre 
of the hindmargin and 3 before the undulate line; transverse lines black, the posterior line finely dentate. 
Hindwing yellowish-white with a brownish-black marginal area and white fringes. Colorado. 
0. levis Grt. (26 e). Forewing light reddish-brown, irrorated with grey and blackish, subterminally levis. 
almost white with black veins, the black transverse lines are double, filled up with white; the long whitish 
coniform macula encircled by black extends to the posterior transverse line, the narrow whitish upper maculae 
are centred and surrounded by black; the undulate line is composed of small white sagittae with black wedge- 
shaped streaks before and behind them. Hindwing yellowish brown with a black marginal band. Colorado, 
Denver, Arizona. 
0. sanina Sni. is very similar to levis, but smaller, less clearly marked, the hindwing less yellowish; sanina. 
the coniform macula is shorter and never extends to the postmedian line, instead of the upper maculae there 
are only lighter small spots, the wedges in the marginal area are faded, not distinct, so that the marginal area 
looks less striped. Expanse of wings: 28 to 30 mm. Colorado. 
0. lepipoloides McD. is so entirely similar to Lepipolys perscripta (26 b) that, in doubtful cases, it lepipoloides. 
is only discernible by the smooth frons. On the forewing we miss the brown colouring at the transverse lines 
which are single, the posterior line being on the submedian fold inwardly angular and less dentate; there is 
no coniform macula and before the undulate line there are no small sagittae. Hindwing brownish white with 
a broad blackish-brown marginal band. Expanse of wings: 32 mm. Canada (Alberta) in August, perscripta flies 
in February until April. 
0. simplex 8m. (26 e) likewise resembles levis , but it entirely lacks the coniform macula and exhibits simplex. 
a large whitish spot behind the postmedian line in the anal half. From Utah and Colorado. 
0. meadiana Morr. has bluish-grey forewings with single black transverse lines, the central area meadiana. 
between them is somewhat darker, without a coniform macula, the round ring-macula is surrounded and centred 
with black, the reniform macula is hued with reddish, between both a faded median shadow, the interrupted 
light undulate line is on both sides marked with blackish. Hindwing whitish with a faded blackish-brown 
marginal band. Expanse of wings: 28 mm. Arizona. 
0. saundersiana Grt. (26 e). Forewing light brown with a golden reflection, in the basal and subterminal saundersia- 
areas irrorated with whitish-grey, the veins in the marginal area black-striped, and double transverse lines, nct - 
all the 3 maculae are small, surrounded with black and centred with brown, between them a faded black median 
line. Undulate line whitish with black wedges before and behind it. Hindwing light brownish, in the marginal 
area faded blackish-brown. Canada, Illinois, Missouri, Texas. 
0. pernotata Grt. (26 e) is similar to saundersiana in the marking, but lighter, more greyish-white, pernotata. 
a little irrorated with brown, only in the marginal area slightly darker, the central area not so prominently 
dark; the coniform macula is, in the shape of a thick black stripe, connected with the posterior transverse line; 
the undulate line is quite indistinct except its anal part, only in the centre with some dark wedges before it. 
From Arizona. 
0. polingi Barnes (26 e) has light brown, postmedianly still lighter forewings with double black polingi. 
transverse lines, large bluish-grey upper maculae surrounded with black, and a very large coniform macula 
which touches the elliptical ring-macula; an intense black median shadow is nearing the posterior transverse 
line in the lower half; marginal area irrorated with brownish, with black veins, before the scarcely marked 
undulate line there are 3 brown sagittary spots in the lower half. Hindwing yellowish white with black border, 
veins, central spot, and postmedian line. Arizona. 
0. fasciata Edw. (26 e) is a small, dark greyish-brown species, remarkable by the broad faded black jasciata. 
median shadow; the double transverse lines are rather indistinct just like the upper maculae which are feebly 
surrounded with whitish; undulate line indistinctly dark with faint sagittae before it and a grey blotch at the 
anal angle. Hindwing light grey, at the margin darkened. Colorado. 
0. occata Grt. (26 e). Forewing light reddish-brown, irrorated with whitish except the central area, occala. 
in the marginal area black-veined, with single transverse lines and a black median line which is thickened at 
the costal margin and hindmargin; maculae in whitish rings, finely encircled with black, with black streaks 
before and behind the undulate line which is composed of small white sagittae. Hindwing light brown with 
a darkened border. Texas, Colorado, Arizona, California. 
0. viriditincta 8m. (26 f) has red-brown forewings tinted with olive-green, with single transverse viriditincla. 
lines being bordered with white on the averted sides, the three small maculae are encircled with black; the 
whitish undulate line is proximally shaded with blackish. Hindwing light brown, on the veins and margin 
darkened. From Canada. 
0. laticosta Dyar (26 f) is recognizable by the broadly lighter costal-marginal part extending down latieosta. 
to the median, below it the light reddish-brown forewing is irrorated with a blackish brown; transverse lines 
quite indistinct and marked by single dots, the posterior line distally slightly edged with whitish; maculae
