R. impexa sp. n. (153 c). Forewing yellowish-grey strewn with black, the larger basal part- as far 
as the very large reniform macula and below it almost quite black, so that only the area of the reniform macula, 
the subterminal and marginal areas as well as the inner margin remain dingy greyish-brown; the markings 
in the basal part are quite extinct; the reniform macula shows inside above a roundish projection in the cell, 
producing the shape of a heart or trefoil-leaf, at its interior edge there is a Y-shaped black mark, and a 
:-shaped mark at its exterior edge, the centre between these two lines filled with reddish-brown; the costal margin 
above it is likewise light, traversed by 2 very oblique black lines the distal one of which is connected with the 
pointed dents of the postmeclian line behind which there are black and white vein-dots; the marginal area 
shows traces of a light undulate line clouded blackish on both sides. Hindwing dark brownish-grey, fringe 
light. Described from a £ from Paramaribo; type in the Senckenberg Museum. 
R. nugax sp. n. (153 c) is very similar to impexa in the marking, but the forewing is red-brown, the 
inner margin, the distal cell-end and an oblique shadow from there to the margin between the veins 2 and 3, 
as well as the margin behind the whitish dentate subterminal line are shaded blackish; the reniform macula 
shaped like a trefoil-leaf and the costal margin above it are greenish-white; the fine black transverse lines are 
distinct here, the anterior one indistinctly double, the posterior one distinctly double, forming an acute angle 
between veins 4 and 5 towards the reniform macula; a red-brown longitudinal stripe near the anal angle contains 
a black streak. Hindwing greyish-brown, darker at the margin, yellowish at the base, fringe yellowish-white. 
From a from Brazil, Coll. Seitz in the Senckenberg Museum. 
R. albidula Dogn. is a smaller species very similar to Ghadisra infanta. Forewing silvery white with 
a black basal spot and 3 blackish-brown transverse lines, a large brown triangular spot behind the foremost 
line at the inner margin, a large costal-marginal spot behind the postmedian line down to the centre of the wing, 
enclosing darker internerval streaks. Hindwing lustrous white with a small anal spot. The $ is more intensely 
strewn with brown and has a brown angular cell-end band and blackened hindwings. Expanse of wings: <$ 34, 
2 42 mm. French Guiana. 
R. myconos Schs. (= pupula Dogn.) (153 d). Forewing light grey with 3 irregular darker basal lines 
and a V-shaped black line in the cell ; behind the double postmedian line follows a series of small black internerval 
spots, a large spot of dense black dusting is before the black submarginal line. Hindwing whitish in the basal 
half, dark grey distally. Colombia, Brazil. 
R. praerupta Dogn. is near myconos; the white forewing is strewn with brown with brown double 
transverse lines and a brown reniform macula surrounded by black; subterminal internerval dots are removed 
farther inwards between the veins 4 and 6 and distally shaded with brown; a spot of brown strewdng is also 
behind the postmedian line at the costal margin. The $ is more intensely marked. Hindwing as in myconos. 
Expanse of wings: <$ 39, $ 42 mm. French Guiana. 
R. condita Schs. (= presbytica Dyar) (153 d). Forewing white strewn with black in the basal third, 
distally bordered by a straight black line which is double below the cell, and traversed by a black line which 
is double at the costal margin. Forewing distally light brown, darkened towards the apex, the reniform macula 
surrounded with black, and with a double red-brown postmedian line behind which there are large black spots 
in the upper two thirds. Hindwing white with a black marginal band. Guiana. 
R. Cassandra Schs. {= longula Drc.) (153 d). The white forewing is strewn with grey and light brown, 
the veins interruptedly striped black, with rather indistinct double grey transverse lines and a large red-brown 
spot at the cell-end, edged and traversed by dark lines; subterminal line whitish, bordered with red-brown in 
the upper half outside. Hindwing white with a dark grey marginal line and blackish hair at the inner margin. 
Venezuela, Colombia. 
R. felderi Schs. (153 d) is an extremely common and widely distributed species with white forewings, 
very scantily strewn with black, with fine double dentate transverse lines, the reniform macula surrounded 
with black; behind the postmedian line there are small more or less distinct black internerval spots in a red- 
bpown subterminal band. Hindwing white with a black anal spot. Mexico to Peru. 
R. bichorda Hmps. is probably a somewhat larger insular form, more densely strewn with brownish 
and without the red-brown subterminal band. The white hindwing is strewn with brown at the margin in the 
only 2 described. Expanse of wings: 46 mm. Nassau (Bahamas). 
R. haitia Schs. is somewhat similar to bicliorda ; forewing light drab, white strewn with brown at the 
costal margin, white with black strewing basally below the cell; both the transverse lines double, brown and 
black, the posterior one very fine and scarcely darker than the ground, a large crescent surrounded by black 
is at the cell-end; subterminal shadow brownish, double in its upper half. Hindwing white, narrowly brownish 
at the margin. Expanse of wings: 35 mm. Haiti.
