Spines fine, slender, no small ones behind them . ophelians Dyar. 
Section I. anellus with a dorsal chitinous tongue. 
S. clarans Dyar. Forewing narrow, oblong, rather pointed; dark red-brown, the veins shaded blackish damns. 
especially at the base and in the middle; 3 white subapical dots and a small sxibbasal one. Hindwing pinkish 
whitish, the veins and a broad inner-marginal area pinkish brown. Expanse of wings: 38 mm. V unknown. 
Peru. 
S. dorans Dyar (164 d). Like clarans , somewhat less red-brown, but in fact only discernible by the dorans. 
3 hypopygium. Expanse of wings: 35—43 mm. 2 unknown. Peru, Colombia (Upper Rio Negro), in the 
Berlin Museum. 
S. tontineans Dyar resembles clarans and dorans , but it is more dark purple without the red-brown tontineans.

S. giseldans Dyar is smaller and more slender than tontineans , otherwise the same, but separated by giseldans.

S. trimacula Sepp (164 d). According to Sepp's figure, the <$ is large, with narrow long forewings, trimacula. 
dark purple brown with a darker central shadow; the dots yellow , 2 subapical ones and 1 subbasal one. Hind¬ 
wing light with a pinkish reddish tint and a dark inner-marginal area. The $ (if if really belongs to this 
species) has a distinctly concave apex and a reddish spot here, with reduced yellow spots. Expanse of wings: 
d 47 mm, 2 57—63 mm. I have not seen any <$. Larva elliptically flattened, with short horns which are ab¬ 
sent on the middle segments; grass-green laterally and in a quadrangular frontal spot, the rest of the dorsum 
yellowish green, the horns purple. The eggs are deposited in a pack: the larvae are at first gregarious, living 
on orange-trees. Guiana. 
S, horrida Dyar (= ? affinis Mschlr.) ( 164 d). Dark purple brown with a silky gloss, wings oblong horrida. 
as in trimacula, dots yellow, very small, variably developed. Hindwing dark brown, rarely somewhat lighter, 
but the inner-marginal area is invariably broad dark. $ similar, apex slightly concave costally; both sexes 
with a darker contrasting area in the cell and at the apex. Hinclwing of often with rough purple scales 
between the veins. Expanse of wings' £ 33—40, $ 50—58 mm. Larva unknown. Guatemala, Costa Rica, 
Panama, Ecuador, Colombia, Venezuela. Moschler's affinis, described according to 1 $ from Surinam, can¬ 
not be safely determinated, though horrida is the only species I have at hand with a sufficiently large $ to 
correspond to affinis: horrida from Surinam, however, I have not at hand. 
S. joyceans Dyar (164 e). Forewing triangular, rather short, dark, less red than horrida; dots white, jo oceans. 
the subapical ones are coherent almost in an oblique line. Hindwing moderately dark, sometimes lighter in

green down to the sides, with a narrow black line above the lateral horns which are very short, absent in the 
middle, light, with a black tip and a black basal ring. It lives on Lansium americanum and other plants.

S. laberia sp. n. is similar to joyceans, but more robust and with broader wings, though of the same laberia.

de Janeiro). 
S. rufescens Wkr. (= determinata Wkr., plora Schs., pallescens Dogn.). Wings of normal shape, rufescens. 
moderately long; dark red-brown, generally on a lighter red ground, veins and cellular area shaded black; 
mostly without any dots, if they are present: — megasomoides Wkr., white. Hindwing pinkish blown, light, megasomoi-

is dark brown, and other dd which I range here are also dark.
