0. delicaiescens Dyar. “24 mm.” Cell-dot of forewing black, of hindwing double, white. The narrow 
purple borders mixed with white, widening between the radials and the hindmargin. Panama Canal zone. A 
larger <$, in poor condition, from Tutaya. E. Brazil, seems to be closely related and belongs to the coendea group. 
0. confluaria Warr. (6 i) differs from sellifera (6 h) in the pectinate $ antenna and the narrower, generally 
lighter-mixed borders. Warren describes the hind wing as “bent at vein 4”, but this is scarcely noticeable in his 
drawing of his type from French Cfuiana, nor in the specimens before me from the Guianas and Para. Hind- 
tibia of fringed. — mesocraspeda Prout is rather paler and more bluish green, the borders with rather strong 
violet-whitish admixture, that of the forewing broadening from the 5th subcostal to the apex. Panama, 1 $. 
0. carnelunata Warr. (4 h) is probably near confluaria, as Warren assumes, but the hindlegs are lost 
in the only specimen known to me, a from Ponte Boa. Borders rather ampler, delicate pink mixed with white, 
dark-edged, finely dark irrorated, anterior blotch of forewing distinctly darkened on the 5th subcostal and first 
2 radial veins. Maroni River. 
0. decoloraria Walk, recalls a dwarfed coerulea or derasa with the terminal line hardly indicated except 
by a very small brown spot at the tornus of each wing, but the antenna of the $ is pectinate. Jamaica. 
0. altonaria E. D. Jones (5 i), Very distinct in its large black, white-pupil led cell-spots. Hindtibia not 
so strongly fringed as in the coendea- group. x41to da Serra, Sao Paulo. 
0. pellucida Prout (7 b). More translucent than coendea and differing structurally in both sexes. $ 
hindtibia not fringed; $ antenna pectinate. Carabaya, S. E. Peru. 
0. ciliaria Hb. (= marginaria Stoll, nom. praeocc., semialbaria Guen.), said to be from Brazil, is 
evidently the same species as pallida, but may, if the figure is accurate, represent a race. Very large, with the 
pale green wings whiter proximally and darkened on the veins. — pallida Warr. (7 b) is uniform whitish green, 
not so translucent as the neighbouring species, the cell-dots minute, the fringes bright rose-pink. Abdomen of 
$ with strong tuft from behind basal cavity. $ larger and rounder-winged than <$. French Guiana (type), 
British Guiana and the Amazons. 
0. dicraspeda sp. n. resembles a dwarfed confluaria (6 i) with simple hindleg, or tricamerata (7 b) without 
the large cell-spots. Borders rather narrower than in them, but generally present also (and dark) on the 
underside. $ pectinations less long than in tricamerata, palpus rather longer. Matto Grosso (P. Germain), 
8 <$<$ in coll. Brit. Mus., including the type. Taperinha, Lower Amazon (Dr. Zerny), 1 in Mus. Wien. 
0. marginata Warr. was founded on a $ from British Guiana in deplorably worn condition, but has 
since been received from both British and French Guiana. Cell-spot of forewing dark red-brown with a pale 
centre, terminal line red-brown, forking at or before the 2nd median, so as to cut off a larger or smaller, in 
part pale spot at hind angle; usually also a small terminal patch is present between the radial veins. Hindwing 
similar, but with the terminal markings generally smaller; a raised white mark on the 2nd discocellular. — 
sympathes subsp. nov. (7 c) is a large, broad-winged race with the terminal spots undeveloped excepting at the 
hind angle. E. Colombia: Upper Rio Negro, 800 m (A. H. Fassl), 5 dd, the type in coll. Protjt. 
0. tricamerata Prout (7 b) differs from the preceding in the additional terminal markings, which bring 
it nearer to rufiplaga obsolescens. Upper Amazons (loc. typ.), French Guiana and (?) Colombia. 
0. rufiplaga Warr. (7 b). A rather large species, with the pale parts of the markings more reddish than 
in marginata, the forewing typically with a better developed terminal spot between the radials, the one at the 
tornus also larger, extending to the middle of cellule 2. Described from S. E. Peru, known also from the Peruvian 
Amazons, Bolivia and Matto Grosso. — obsolescens Warr. apparently represents rufiplaga at Fonte Boa; the 
terminal spot between the radials is inclined to disappear (but is very variable), while there is often some 
development of the border on the anterior part of the hindwing. From tricamerata all forms of this species 
differ in lacking the central terminal spot of the hindwing and in the structure: pectinations of $ antenna less 
long; palpus of $ with 3rd joint only about half as long (in tricamerata almost equal to diameter of eye). 
0. trilunaria Guen. (4 g). Unmistakable an account of its large spots and their coloration. Moreover 
it is the only species of the group yet known from the more southerly parts of Brazil. 
0. fractimacula Prout {= ruptimacula Warr., nom. praeocc.) (7 e). Near congener, but with the cell- 
spots smaller and more rounded, the anterior terminal spot of the forewing narrower, the apical of the hindwing 
broken into two small ones, the anal much reduced. La. Union, Carabaya, S. E. Peru.
