0. bifenestrata Schs. (141 g) is probably a southernmore representative and hardly specifically different, bifenestrata. 
It is distinguished by a more complete (at least in the costal-marginal portion) black fine antemedian line, the 
nebulous band behind it being grey, hardly brownish, and much narrower; at the cross-vein there is often a 
black dot; the postmedian grey nebulous band is very narrow, too; fringe at the ends of the veins lighter 
speckled. Hindwing blackish-brown, at the margin darker. Described from Costa Rica, also from Rio de Janeiro 
and Sa. Catharina there are numbers of similar forms before me, thus apparently widely distributed. 
0. maya Schs. (141 g) may be the somewhat more differentiated Mexican intermediate form between mayu. 
the two preceding ones. Smaller, of a soft light grey, very scantily strewn with black, the hardly darker grey 
transverse bands as in bifenestrata , the postmedian one outside more distinctly defined by a blackish notched 
line, at the cell-end with a fine black dot; subapically only a hyaline spot; fringe only between 2 and 4 blackish- 
brown. Hindwing light reddish-brown. Jalapa; Colima. 
0. magniplaga Schs. (141 g). Also like maya, somewhat larger, slender, apex of forewing more produced, magniplaya. 
the margin below the angle somewhat more oblicpie; marked like the 3 preceding species, but easily discernible 
by the reddish-brown marginal spot forming the exterior border of the undulate-dentate submarginal line and 
occupying the whole marginal area down to 2, being broadest between 4 and 6, where it borders on the large 
quadrangular hyaline spot. Hindwing reddish-brown. Panama; Costa Rica. 
0. nigripuncta Schs. (141 g) belongs to the same group and is recognizable by the black inner-marginal nigripuncta. 
spot forming the lower end of the antemedian band; the two nebulous bands are chiefly darkened in the costa 1 - 
marginal portion, especially the postmedian one in the costal-marginal third behind the cell; moreover, the 
markings are rather extinct except the postmedian row of vein-dots; the subapical hyaline dot is very small, 
below it another small blackish spot; the ends of the fringes are blackened. Hindwing brownish-grey. Guate¬ 
mala; Costa Rica. 
0. interniplaga sp. n. (141 h) is similarly marked as nigripuncta, but at once discernible by the two intemi- 
deep blackish-brown large inner-marginal spots each of which forms the end of the two darker transverse bands; plaga. 
ground-colour ochreous brown, in the $ more red-brown; in the latter the whole antemedian band is darkened 
blackish, the distal margin being very strongly notched. Female type from Arouary (Cayenne), male type 
from an unknown habitat, both in the Berlin Museum. 
0. reperta Wlcr. (141 h) is somewhat similar, but the two inner-marginal spots are absent, the reperta. 
ground-colour is more a coppery red-brown, strewn with lilac whitish, the margin is much less strongly notched; 
the anterior faded transverse band is very broad, tinted purple, the posterior one is narrower, hardly curved 
round the cell-end, in interniplaga very strongly so; the other markings are the same. Hindwing reddish-brown. 
Guiana; Brazil. 
0. basifusca sp. n. (141 h) is allied to reperta -, ground-colour greyish-brown without a red tint, the whole basifusca. 
basal area as far as the exterior edge of the black antemedian band, which is more oblique than in the other 
species, densely strewn with black; the interior border of the antemedian band is distinct and irregularly 
notched, projecting with a pointed tooth on the median vein towards the margin; postmedian band more 
intensely blackened only at the costal and inner margins, at the inner margin it approaches the anterior band; 
marginal area with hardly any markings, the hyaline spot quite yellowish-green, oblong-quadrangular, outside 
bidentate; fringe black, crossed light on the veins. Hindwing blackish-brown with a reddish reflection, beneath 
greyish-brown, irrorated, with a black discal dot, a brown median line which is angular between 5 and 6, and 
an undulate-dentate subterminal line. Type: 1 $ from Campo Bello (Rio de Janeiro) in the Coll. Zikan. 
0. microps Wlcr. (141 h) is a more common species. Forewing on the light reddish-brown ground densely microps. 
strewn with brown and coarsely with light lilac grey, below and behind the cell-end the light ground-colour 
is somewhat more prominent; antemedian line fine, irregular, black, below 1 removed towards the margin, 
behind it a hazy greyish-brown transverse band; at the upper cell-end a fine black dot; postmedian line greyish- 
brown, behind the cell and submedianly excurved, between basally concave, between this line and the undulate 
subterminal line a few black vein-dots; hyaline spot light greenish, quadrangular, outside concave, finely 
encircled by black, behind and below it traces of a dentate short submarginal line which is mostly somewhat 
broader rusty brown below the hyaline spot. Hindwing brownish, lighter in the basal half of the costal margin, 
with 2 dark, median and postmedian transverse lines, the latter beneath not denticulate. Brazil. 
0. amoria Drc. (141 h), well figured in the Biologia, is very near to microps and the following indentata ; amoria. 
larger and more slender than microps, and of a light reddish-brown ground-colour, scantily strewn with grey, 
the light brown bands as in microps, with a black cellular dot and a white subapical hyaline spot. Hindwing 
reddish brown with a narrow brown postmedian line. Fringe darker brown. Central America to Ecuador 
and Brazil. 
0. indentata Schs. (141 i) is extremely similar to microps, somewhat larger and more slender on an indentata. 
average, looking somewhat lighter owing to its being less strewn, especially in the discal area; antemedian band 
more oblique, more notched in its exterior border, both the bands brighter reddish-brown at the costal margin:
