0. leda Drc. (121 d). Wings narrower than in naemia, lobe of forewing broader, the two incisions below leda. 
the apex of the hindwing deeper, the distal margin below it forming a straight line. Otherwise coloured and 
marked as the preceding species. Genitally different: the lobes of the 8th sternit longer etc. Peru and Amazons. 
0. erosa Jord. (121 d). Exterior scarcely different from leda, but genitally distinctly separated by the erosa. 
apically narrowed triangular lobes of the 8th sternit etc. Guiana. 
0. nubila Jord. likewise shows two indentures below the apex of the hindwing, the corners between nubila. 
them are sharper than in naemia. More unicoloured loamy brown, marked like the other species, the lowest of 
the 3 black dots at the anal angle of the forewings is larger than the others. Discernible by the spoon-shaped 
lobe of the 8th sternit. 2 geographical forms: the nomenclatural type from Colombia is intensely marked 
greyish-white, the 3 anal dots on the forewing are large. The lobes of the 8tli sternit are short, their interior 
surfaces deeply concave. — acuta Jord. (121 e), from Nicaragua, is more unicoloured, the 3 anal dots very acuta. 
small or extinct except the lowest. The lobes of the 8th sternit are apically narrower, the interior surface less 
concave. 
0. bicomis Jord. is externally not separable from leda, but genitally quite different: the 8th sternit is bicornis. 
extended into a long bent thorn on each side etc. South-Eastern Brazil (Santos; Castro). 
0. peregrina Cr. (121 e). Forewing more uniformly dentate, the lobe much less projecting in the centre; peregrina. 
hindwing with 2 deep indentures below the apex and a short tail below it; distal margin below it straight as far 
as the somewhat lobate anal angle. Ground-colour deep brown, mostly lighter basally and at the margin 
before which, in the lower half, there are oval loamy brownish spots; forewing often dusted bluish-white, like 
spots. The $ is mostly lighter, more loamy brownish, more distinctly marked. Known from Guiana, the 
Amazons, and Peru. 
0. epiphaea Jord. (121 e). Wings shaped as in peregrina, but the forewing is without the small dent epiphaea. 
below the apex and that above the anal angle. Monotonously dark chocolate. The <$ antennae are longer 
pectinated than in peregrina, the lobes of the 8th sternit truncate, its corners extended into long thin bent 
thorns (triangular with a rounded apex in peregrina). Peru. 
0. plettina Jord. is somewhat smaller than peregrina, otherwise of the same exterior; the pointed lateral plettina. 
appendages of the 8th sternit are proximally broader than in epiphaea and bent backward distally. Ecuador. 
0. beprea Drc. (= mirabilis Drc. nec Cr.) (121 e) is a smaller species; apex of forewing much sharper beprea. 
pointed, the margin very slightly dentate or quite smooth, tail of hindwing less pointed than in the preceding 
species. Colouring most variable, loamy yellowish, wood-brown, or dark brown, markings very similar to those 
of the preceding species. Antennal dents longer than in peregrina. The lateral appendages of the 8th sternit as 
in plettina. Panama, British Honduras. 
0. angulata Cr. harpago Hbn., zerbina Cr.) (122 b) is also of a most variable colouring, and size, angulata 
Loamy brown or dark sepia-brown above, the dark oblique line of the preceding species is absent in the C, 
whilst it is more distinct in the light yellowish or reddish-brown $. The 8th sternit with a double excision and 
rounded sides, the middle lobe mostly reduced to a dentiform appendage. The black larva with rusty yellowish 
and whitish-grey spots resembles bird’s droppings, the metathoracic lobes are dingy tan-coloured; on Randia 
formosa. Guiana, Venezuela, Amazons, Para. 
0. ferruginea Wkr. (= zerbina Wkr. nec Cr.) (122 b) is exactly like angulata and just as variable, but the ferruginea. 
sides of the 10th tergit are much deeper indented, scarcely so in angulata. , etc. Larva similar to that of angulata. 
Panama to Venezuela, Bolivia and Matto Grosso. 
0. gigantea Drc. Contours of wings similar as in beprea, but much larger; its colour varies between gigantea. 
ochreous and dark brown, dusted with greyish-white, oblique line double, filled with whitish. The 8th sternit 
is laterally extended into long pointed horns. Ecuador and Peru. 
0. spadix Jord. is allied with gigantea, to be separated by longer antennal dents of the J 1 . Yellowish- spadix. 
ochreous above, shaded with purple red and dusted with greyish-white, the double oblique line stronger than 
in gigantea, the interior line stronger than the exterior line. In the only specimen known hitherto, described 
from the Colombian Cordilleras (Alto de las Cruces), the genital organ differs from that of gigantea. Length 
of fore wing: 36 mm. 
3. Genus: If ©moeopteryx Jord. (. Fldr.) 
Separated from the preceding genera by the uppermost subcostal branch arising from the cell and 
6 being stalked with 7 on the hindwing. Margin entire, apex sickle-shaped. The small heap of scales in the 
lower cell-angle is absent. Antennal pectinations longer than in Oxytenis. 5 species are known. 
Type: malecena Drc.
