hindhead; the collar, thorax and costal margin are light red-brown, the hindwing is light yellow, reddish-brown 
only at the costal margin; this race may be named — meridana /. n. (159 c). 
R. epigena Stoll (159 d) is very similar to thestia and recognizable by the brownish-white colour of the 
marginal and discal spots, the former of which is very notchedly defined inwards. The typical form from Guiana 
shows the frons red-brown, the middle head green and the hindhead silvery white, with a brownish-grey collar 
and mesothorax. Abdomen yellowish, brownish dorsally. Hindwing yellowish, brown at the costal and distal 
margins. Mexico to Paraguay. This species is also variable. Specimens from Peru and Bolivia have a widened 
marginal spot, an almost white costal margin of the forewing, and a much darker brown hindwing: — boliviana 
/. n. — while those from Brazil and Paraguay — meridionalis /. n. (159 d) — have much lighter hindwings, 
the costal margin, collar and thorax also turning almost white. 
R. tanampaya sp. n. (159 e). Beside epigena boliviana, another very similar species occurs in Bolivia. 
It only differs in the very narrow and almost purely white marginal spot with a quite uniformly undulated 
rounded interior border, the fringe in its environs being also white, separated from it by a dark brown marginal 
line, the spot reaching besides down to the submedian fold, the fringe below it being green; the white discal 
spot is reniform, not round; costal margin and frons white, hindwing almost white, only very scantily strewn 
with brown, with a somewhat undulating brown marginal line, the fringe speckled dark brown. Abdomen 
almost white towards its end. Forewing beneath greenish-white, costal margin white, subcostal area and the 
very narrow marginal spot dark brown. Hindwing yellowish-white, a brown strigiform spot above vein 6. 
fringe speckled dark brown. Rio Tanampaya, Bolivia (La Paz), Coll. Staudinger in the Berlin Museum. 
R. excavata Schs. Head and thorax cpiite unicoloured green, abdomen yellow, darker in the q' than 
in the $. Forewing with a slight concavity below the apex, the fringe within being white, otherwise brown. 
Costal margin very narrowly yellowish-brown, an indistinct discal dot is white. Hindwing of $ yellowish- 
brown. of $ yellow. Under surface of yellowish-brown, of $ yellow with a brownish shadow in the marginal 
concavity, the hindwings with blackish-brown marginal dots. Expanse of wings: 36 mm. From Brazil (Petropolis). 
R. dealbata Docjn. resembles the following deolis-, frons white, vertex and tegulae green; collar and 
mesothorax of a colour like “coffee with milk”, abdomen above white intermixed with grey, beneath all white 
like the legs. Forewing with a white costal margin and cellular spot, the marginal spot is narrow as in deolis, 
but white like the fringe which is intermixed with some grey. Hindwing purely white, speckled somewhat 
grey on the ends of the veins. Loja (Ecuador)-. 
R. deolis Cr. (159 d). Shape of wings similar as in the thestia- group, but the notch on the forewing is 
situated between the veins 5 and 6, and the costal margin shows a distinct prominence behind the middle. 
Head and tegulae green, collar and thorax dark brown; discal spot dark brown, in a yellow ring; margin inclusive 
of fringe between 2 and the apex narrowly dark brown. Hindwing and abdomen light ochreous, hindwing 
more or less brown at the margin. Beneath greenish-yellow with a rusty red costal margin, a dark brown mar¬ 
ginal spot and 3 or 4 green strigiform spots between the apical veins, hindwing ochreous, costal margin, apex 
and distal margin red-brown. - brunnescens Dogn. is a form with quite brown hindwings and abdomen, 
described from S'.’ Paulo de Olivenca (Amazons). 
R. apicalis Wkr. (159 d, e) looks almost the same and may be merely a form of it, distinguished on the 
forewing by the brown marginal spot widening inwardly in the shape of a notch between 5 and 6, the purely 
yellow hindwing lacking the brown margin. The discal spot is often enormously large in the $$, we figure 
such a $. Described from Honduras, occurring also from Mexico to Colombia and Guiana. 
R. dolorosa Drc. belongs yet to the same group with a dentate distal margin and is discernible by the 
head and collar being all white, with a brown thorax and green tegulae; abdomen and legs yellow. Forewing 
dark green, white at the costal margin, with a large brown cell-end spot and a brown marginal spot. Hind¬ 
wing light yellow, black at the costal margin and apex. Expanse of wings; 38 mm. Brazil (Cabo). 
R. aethra Drc. (159 e) introduces a group of smaller species with notchless wings and a more or less 
distinct inner-marginal marking, aethra has the most strongly pectinated antennae. Head and thorax green, 
only the frons and a longitudinal stripe at the interior margin of the tegulae are whitish; abdomen pale ochre. 
Forewing light green costal margin very narrowly reddish-yellow; a very fine dark dot at the cell-end. a fine 
yellowish longitudinal streak in the basal half of the inner margin is bordered with black above and widens 
in the centre of the inner margin, forming a semicircular thickening. Hindwing purely white. Forewing be¬ 
neath pale greenish, the costal margin as well as the chest and anterior femora are orange. Mexico to Colombia. 
R. nadina Schs. (159 e) is similar, but the head is white, green only in the neck. Forewing darker green, 
the costal-marginal stripe of a purer white, widening somewhat and more yellowish towards the apex, the 
cellular spot larger, dark brown, in a yellowish ring, the white inner-marginal stripe extends only over a third 
of the inner margin and is bent up here to a short vertical white streak. Hindwing feebly suffused with pink, 
abdomen salmon-coloured orange. Guiana. 
R. zikaili sp. n • (1^9 e ) is allied to nadina. larger, slimmer, lighter green, the head almost quite green, 
zikani.
