0. semipotentia Dyar (51 h) is one of the very smallest species with an expanse of bnt 13 mm, narrow semipoien- 
wings, dark brown with a light flesh-coloured reniform macula bordered with black, a similar spot above it, 
forming an oblique costal-marginal spot with a distal dent; the apical area behind it is dark, the margin below 
it light; the very feeble straight transverse lines are light, bordered with dark. Hindwing brownish-grev. 
Mexico (Tabasco). 
0. choruba Dyar (51 h). Forewing bronze red-brown, dusted with dark lilac grey as far as the post- choruha. 
median line and from here triangularly to the apex; the distally dotted reniform macula is incompletely 
surrounded by black and situate in the light distal area, the darker undulate line is rather indistinct. Hindwing 
dark brown. Mexico (Jalapa). 
0. sciaphora Hmps. (= laurea Drc., part.) (51 h) has grey fore wings strewn with brown, the interior sciaphora. 
half of the median area being darkest, with dark transverse and median lines, the postmedian line double; 
the undulate line is composed of black double dots filled with white, with a white c-shaped mark in the discal 
fold. Hindwing greyish-brown. Mexico (Jalapa). 
0, costata Hmps. (51 h) is larger than sciaphora , otherwise very similar, with a more distinct whitish rostata. 
reniform macula surrounded by black, recognizable by a flat blackish triangular spot at the costal margin behind 
the postmedian line, without the light marking on the discal fold in the undulate line. Mexico to Argentina. 
0. excurvata Hmps. (51 h) is a smaller greyish-brown species with double white-filled transverse lines e.rmrvaia. 
and white maculae surrounded with black, the ring-macula is a dot, the reniform macula distally prolonged at 
both its ends; the undulate line is composed of black dots. Argentina. 
0. catilina Drc. (51 h), according to Dyar belongs to this place (it had been described as Eustrotia ); catilina. 
forewing purple brown, strewn with black as far as the median line, red-brown in the marginal half, with 
double transverse lines filled with red-brown, a small black triangular spot at the costal margin behind the 
median line, a larger costal-marginal spot behind the postmedian line: the double undulate line is filled with 
whitish. Hindwing brown. Mexico (Tabasco). 
0. tilora Dyar (51 i), described as Erastria, has brownish ochreous forewings being more red-brown tilora. 
in the median area and loamy grey in the marginal area, with double transverse lines, the exterior one filled 
with whitish, with 2 postcellular dents; spotted leaden grey behind the reniform macula, with 3 black costal- 
marginal streaks. The white undulate line cuts a little triangle off from the broadly triangular dark brown 
apex. Hindwing light grey. Mexico (Puebla). 
0. oplora Dyar (51 i) is very closely allied to tilora , but smaller and darker, less intensely marked, deep nplora. 
brown in the basal half, distally more pinkish-brown, with the similarly coloured reniform macula, the whitish 
postmedian line forming the same two dents behind it, between which there is a black blotch outside; behind 
the dark undulate line a narrow light area. Hindwing dark blackish brown. Panama. 
0. hemitecfa Dyar (51 i) is very similar, the basal half monotonously dark brown, the distal area of a hemitecfa. 
light ochreous tint, the interior transverse and median line only feebly visible, the exterior one as in the two 
preceding species; a black spot below the yellowish reniform macula; the rather indistinct undulate line is light, 
irregular. Hindwing dark brownish-grey. Venezuela. 
0. bascura Dyar (51 i) from the same affinity is larger, dark purple brown at the base, light ochreous bascura. 
outside, the fine median line is distinct, black, the single postmedian line is curved round the reniform 
macula without the two dents of the preceding species, the light distal area traversed by 4 fine red-brown lines, 
the subterminal one of which is shaded with black, a dark costal-marginal spot before it is truncatelv triangular.

0. agraria Schs. (51 i). Forewing brown, lighter at the distal margin, dusted with blackish at the agraria. 
base, with indistinct double transverse lines filled with reddish-yellow, the posterior one with 2 dents in the 
upper half; the reniform macula is situate in a long reddish-yellow costal-marginal spot, behind this macula 
a blackish-brown shadow to the reddish-yellow undulate line behind which there is a velvety blackish-brown 
costal-marginal spot. Hindwing greyish-brown. Costa Rica. 
0. concolor Hmps. exhibits lustrous red-brown forewings with slightly undulated white transverse concolor. 
lines, the exterior one bordered with darker brown inside, a white discoidal streak before it; traces of a darker 
undulate line, excurved in the middle. Hindwing lustrous red-brown with black marginal dots. Expanse of 
wings: 18 mm. Peru. 
0. ailgulilinea Sch.s. (51 i). Forewing brown, anterior transverse line double, filled with light, posterior angulilinea. 
line very fine black, followed by a light pinkish-brown line, with a light brownish pink discal streak at the 
cell-end; the light irregular undulate line is shaded darker inside. Hindwing brownish-grey. Costa Rica. 
0. onytes Schs. (51 i). Forewing brown with a grey antemedian line bordered with red-brown, and a onytes.
