B. Antennal pectinations in the $ long, costal vein of hind wing closely 
appressed to (commonly anastomosing slightly with) subcostal, abdomen 
with (nearly always white) bosses or rudimentary crests (only wanting in some 
forms of herbaria). 
R. leucoceraria Snell. (4 d) is the only known species of the group in which the dark border forms a 
strong spot at the hind angle of the forewing but is otherwise almost entirely unexpanded. Colombia, chiefly 
in the Bogota district. 
R. suppomposa Prout differs from pomposa (4 h) in being rather brighter green, the cell-spots redu¬ 
ced to small dots, the red terminal line on both wings swelling slightly at its posterior end, but not forming 
any large spot as in leucoceraria. N. Argentina. 
R. pomposa Dogn. (= diaphana Warr.) (4h). As thinly scaled as leucoceraria, the cell-spots rather 
large but not ocellated, the terminal line almost simple, only expanding slightly midway between the veins. 
3rd joint of palpus slightly longer than in suppomposa. Ecuador (type) and Peru. — indecora Prout, described 
from Mexico, is smaller, the cell-dots nearly as in suppomposa, the terminal line scarcely expanding between 
the veins. Known also from Nicaragua. 
R. irregularia Barnes <£• McD. is unknown to me, but may be placed here. Expanse 19 mm. Brighter 
green than the preceding, costa of forewing narrowly white; antemedian line with prominent angle in sub¬ 
median fold, postmedian very irregular and strongly dentate, strongly outbent at 3rd radial to 1st median, 
then sharply inbent; cell-dots small; the red terminal line interrupted by white dots at veins. Texas: Browns¬ 
ville, founded on 2 
R. venustula Dogn. (4 e). Smaller than leucoceraria (4 d), with smaller cell-spots (or dots) and brighter 
red terminal markings, which form a smaller posterior expansion on the forewing but also expand a little 
towards the apex of the hindwing. Described from Ecuador, distributed from Colombia to Peru and to French 
Guiana and the Lower Amazon. 
R. isolata Warr. (4 e), also with small cell-dots, is characterized by the small triangular midterminal 
spots. Grenada; also received from Porto Rico, St. Vincent and Bequia Island, off St. Vincent. Possibly a 
very extreme form' of the following. 
R. gerularia Hb. (= ocellata Stoll, nom. praeocc.) (4 d) is variable but easily known by the large 
terminal blotches, 2 on the fore-, 3 on the hindwing. In the type, the cell-marks are punctiform. —- In ab. 
marginiplaga Walk. (= rufidorsaria Snell., jucunda Feld., xysteraria Hulst) the cell-marks (at least on the 
forewing) are enlarged into spots, in the most extreme development quite large and with pale pupils. Described 
from Surinam, this species is distributed everywhere from Central America, Florida and the West Indies to 
S. E. Brazil. 
R. decorata Warr. (4 e) has the midterminal blotch of the forewing smaller or, if elongate, less rounded, 
definitely bipartite, the green ground-colour cutting it at its end or even as far as to the terminal line; the 
midterminal blotch of the hindwing wanting or quite short and not definitely separated from the apical. 
Colombia, Ecuador (type) and Peru. 
R. dependens is another variable species, best recognized by its large cell-spots, that of the forewing 
nearly always joined to the costal border; this latter is very characteristic, broader than in the other species 
and emitting a triangular or comma-shaped mark at the commencement of the postmedian line. —- megastigma 
Warr., from Costa Rica, has the purple markings rather dark and dull, the terminal line of the forewing forming 
a small or moderate expansion between the radials. — tumefacta Prout (4 d) is very similar to megastigma, 
perhaps not always rigidly differentiable; purple markings slightly less dark; cell-spot of forewing generally 
narrower and more angular; borders more irregular in approaching the tornal expansion. Colombia; similar 
forms also in Venezuela and Ecuador. — dependens Warr. (4 e) has the borders more reddish than in mega¬ 
stigma , fairly broad but with little (no central) expansion. E. and S. E. Peru, up to 6000 feet; also in E. Bolivia. 
- independens Prout has all the purple-red markings somewhat reduced, so that the cell-spot of the forewing 
is less strongly confluent with the costal streak, sometimes entirely free. S. E. Peru: Oconeque, Carabaya, 
7000 feet. 
R. bidentifera Warr. (4e). Borders still darker, but bisected by a broad, pale violet line; border of 
hindwing of nearly uniform breadth, that of forewing very narrow where it meets the costal streak, gradually 
widening; cell-spot confluent with a triangular projection from costa. Colombia (type), E. Ecuador and Peru. 
R. atrapes Druce (5 c), in its typical form from Panama, is only known to me in 3 These are 
small (18—23 mm), with small cell-dots, the red at costa of forewing only well-developed basally, the terminal 
marking between the radials small, almost cleft by the 2nd radial, the posterior patch indented at the 2rd
