R. puntillada Dogn., according to the description, differs from nigricincta (4 a) in having only a black puntillala. 
dot at the base of the abdomen, no black blotch at the base of the forewing, etc. I should suppose it to be 
a species intermediate between scotocephala (3 K) and nigricincta (4 a), though M. Dognin inclined to sink 
the latter to it. Loja, Ecuador. 
R. nigricincta Warr. (4 a). Hindwing with 1st median separate, as in the jmeceding group. Posterior nigricincta. 
part of thorax, base of abdomen and base of both wings heavily blackened, otherwise the dark markings are 
only strong on the anterior part of the fore wing. Carabaya, S.E. Peru. I have seen it also from Huancabamba, 
Cerro de Pasco. — fassli form. nov. is rather smaller (length of a fore wing 15 mm), the forewing relatively fassli. 
a little shorter, with the dark markings about the cell-spot more extended, reaching nearly to the 2nd median 
and followed by a rather strong, sinuous line from behind the base of the 2nd median to the hinclmargin. E. 
Colombia: Upper Rio Negro (A. H. Fassl), a few the type in coll. L. B. Prout. Perhaps a separate 
species, as the 1st median of the hindwing is connate with the 3rd radial. 
R. exertata Moschl. (4 a). Crown green, not (as in the three preceding forms) white. The brown markings excrtata. 
less mixed with black, less consolidated at costal margin of forewing, basal patch more interrupted by green 
spots, etc. 1st median of hindwing stalked. Described from Surinam, not rare in French Guiana and reaching 
Colombia and Costa Rica. 
R. radiolinea Prout (4 a) is perhaps a form of exertata , as it has a similar green crown. The outer radiolinea. 
band of the forewing is broadened anteriorly, almost or quite touching the subterminal dots; the brown streak 
between the 2nd and 3rd radials is long and strong, its middle line sharply black. Upper Amazon, perhaps 
with a race in S.E. Peru and Bolivia. 
R. conspersa Warr. (4 a) has the markings less dark, but considerably diffused, on the forewing conspersa. 
variable in detail. The broad suffusion on the hindwing from the median line nearly to the subterminal is 
characteristic. 1st median of hindwing generally about connate, but varying a little in each direction. Common 
in S. E. Peru. 
R. hypotiches sp. n. Smaller than conspersa (31 mm), fore wing with costa less arched. Structure hypotiches. 
similar, pectinations at least as short. Fore wing with the markings darker basally and anteriorly, those around 
the black cell-mark followed by a broad irregular band which runs outward between the radials and joins, 
at a right angle, an equally broad subterminal band which runs to the costa; posterior part of this subterminal 
band weaker, slender, strongly bent inward about the second median; a clear green area proximal to the last- 
named. Hindwing with the suffusion more solid than in conspersa, light purple-drab. Underside characterized 
by the presence of an irregular subterminal band, mostly slender, but broadening triangularly from 3rd radial 
to costa of fore wing; fore wing also with a blackish cell-spot and faint traces of the markings of upperside. 
Ecuador: Balzapamba (M. de Mathan), 3 d'd' in coll. Brit. Mus. 
R. penthica Prout (5 g) is recognizable at once by the extremely extended blackish markings, scarcely pentliica. 
any green remaining except at the discal margins. Huancabamba, E. Peru, only type known. 
R. ozalea sp. n. (4 a as ozolea). Strikingly distinct in the firm median and subterminal lines, the 
transversely elongate cell-mark of the forewing and its accompanying longitudinal pattern of brown lines. 
Underside with the same markings very faintly reproduced. Crown of head green. Hindwing a little more angled 
than in most of the group, 1st median shortly or scarcely stalked. Costa Rica: Orosi, 1200 m (A. H. Fassl), 
a few d'd'; type in coll. Prout. 
R. conflua Warr. (4 b) has the markings more mixed with vinaceous than in exertata and radiolinea, 
more definitely formed into bands, the crown of the head also partaking of this colour. Hindwing with 1st 
median separate. S.E. and E. Peru, the type from Santo Domingo, Carabaya. 
R. pulverata Dogn. (5 c). Colouring as in conflua, but with the markings differently disposed: ante- pulverata. 
median of forewing more slender, of hindwing broken, a broad anterior suffusion from cell-spot of forewing 
outward. 1st median of hindwing about connate. E. Colombia, 500—800 m. Also known from Ecuador. 
R. oppleta Warr. (4 b). Markings rather darker, still more extended, the outer band of the hindwing opplcta. 
reaching the distal margin anteriorly and posteriorly, leaving only a quite narrow green streak between the 
1st radial and 1st median. Smaller, the $$ reaching the size of the d'd' of the two preceding species. 1st median 
of hindwing about connate, varying a little. S.E. Peru. More recently obtained by Fassl on the Upper Rio 
Negro, E. Colombia. 
lafayaria- group. 
Abdomen above predominantly red-brown, usually with conspicuous white spots. Hindwing rounded, 
its abdominal edge in part red-brown, the 1st median variable (just separate to shortly stalked). Both wings 
with red-brown markings, usually expanded into ornamental borders.
