0. hayesi Grt. (26 d) has a light reddish-brown ground-colour, in the marginal area more brown, 
the undulately dentate transverse lines beginning at the costal margin with black spots, between the light- 
ringed maculae with a faded brown median line; undulate line only marked by a darker proximal shading. 
Hindwing orange, dusted with brown, with a broad black marginal band. From Canada, Colorado, and California. 
0. regina Sm. (26 d) is marked somewhat like hayesi, but smaller, with broader wings and of a 
very much lighter colour, light grey mixed with ochreous yellow and often tinted pink, not distinctly marked. 
The hindwing is lighter yellow, the marginal band narrower. Canada. 
0. corusca Sm. (= ate Dyar) (26 d) is a very small, black species with a silky lustre, strewn with 
white, particularly in the basal and subterminal areas; transverse lines whitish, particularly the anterior line 
very indistinct, the upper small maculae in whitish rings; the white undulate line becomes more distinct 
anal wards. Hindwing orange with a moderately broad black marginal band. California. 
0. exemplaris Sm. (26 c). Forewing greyish-white, strewn with blackish, the two black transverse 
lines distally edged with white, the posterior line double at the costal margin; the small, blackish-pupilled 
maculae are encircled with whitish, before the irregular whitish undulate line proximally darkened with blackish 
and minute black sagittae; the marginal area behind them is lighter. Hindwing black, with a large, triangular, 
whitish diseal spot not reaching to the proximal margin, with a black discal spot in it. California. 
0. albifasciata Hmps. ( = fasciata Sm.) (26 c) is larger than the preceding, similarly marked, behind 
the postmedian line broadly brightened up by whitish, in the basal area light ash-grey. The white band 
of the hindwing extends to the proximal margin. Canada, Colorado, California. 
0. melantho Sm. (26 d) is still larger, with an ochreous-whitish body, the forewing whitish, mixed 
with blackish and ochreous-yellow; transverse lines double, the posterior line dotted white on the veins; ring- 
macula round, whitish, reniform macula yellow, encircled with black, between both a broad black median 
shade; undulate line on both sides edged with blackish spots. Hindwing black, with a light yellowish median 
band and a black discal spot and black veins. California. 
0. pudorata Sm. (26 c) is on the blackish-brown forewing mixed with grey and postmedianly dusted 
with white, the blackish transverse lines are rather indistinct, faded; the upper maculae in grey rings with 
a faded median line between them; the dentate undulate line is shaded with dark, proximally with minute 
sagittae. Hindwing whitish, basally dusted with dark, with a black marginal band. Canada. 
0. tenuifascia Sm. (26 c) is distinguished by a very narrow white discal band on the blackish-brown 
hindwing. Forewing brown, dusted with blackish and grey, postmedially somewhat whitish; the transverse 
lines are double, the posterior line filled up with whitish, the small maculae in whitish rings; before the light 
undulate line there are minute black sagittae. Colorado. 
0. balteata Sm. (26 c). Forewing in the basal half reddish-yellow, dusted with dark brown, behind 
it broadly white as far as the blackish-brown marginal area; transverse lines double; the ring-macula is small, 
brown, encircled with black and in a white ring, the reniform macula very large, incompletely encircled with 
reddish; the irregular undulate line consists of small white lunae near the margin, proximally and distally 
irregularly spotted black. Hindwing white with a broad black marginal band. Described from Colorado. 
0. terminalis Sm. (26 d) is a much larger species, reddish-brown, in the marginal area darkened 
with blackish, the transverse lines marked by small black spots at the costal margin, otherwise by single black 
dots, the small maculae are ringed whitish: the veins of the marginal area striped black, between them with 
the small black and white sagittae of the undulate line. Hindwing as in balteata. Colorado. 
0. linda B. <£• McD. (26 c) resembles regina in the marking of the forewing, but it is easily 
distinguishable from it by the transparent white hindwing with a brownish-grey marginal band; forewing white, 
brownish-yellow, in the marginal area dusted with smoke-brown, with blackish transverse lines starting from 
large black costal spots, the maculae encircled with ochreous-yellowish. From California and Arizona. 
0. lindseyi nom. nov. (= punctilinea B. <£• Linds, nee Hmps.) is very closely allied to linda (26 c), 
the ground-colour of the forewing varying from a yellowish pink to a pinkish brown, transverse lines blackish, 
starting from large costal spots, the posterior line intensified by dots on the veins which are often singly present; 
behind it the ground-colour is blackish as far as the undulate line, where it is sharply defined towards the marginal 
area in which the veins are marked black; the maculae are somewhat lighter than the ground. Hindwing 
transparent white with a sharply defined, broad, brownish-grey marginal band. Expanse of wings: 29 to 32 mm. 
Arizona, taken in September, October. 
0. deceptiva B. & Linds, is also allied to the preceding; forewing whitish, feebly dusted with 
reddish-yellow, and strewn with brown, except the surroundings of the posterior transverse line, the most 
densely before the median shade; transverse lines like in the two preceding, but the posterior line without dots 
on the veins; the whole distal-marginal area almost to the postmedian line is blackish, only occasionally there 
are light scales indicating the course of the undulate line. Hindwing as in lindseyi. Expanse of wings: 29 to 
32 mm. Arizona.
