base. Hindwing deep yellow, red along the inner margin, with a narrow dark transverse band. Body orange, 
redder above, with a large white spot on the base of the abdomen. Brazil (Rio de Janeiro). 
S. arpi Schs. (136 b). Forewing deep orange, veins, inner margin and distal margin grey, a large 
triangular median area also grey, its upper edge occupies almost the whole costal margin, bordered by darker 
lines which are united at or above the inner margin and often surround here a tiny white spot; a large orange 
spot at the cross-vein, a white one at the base. Hindwing brownish in the larger inner-marginal half. Brazil 
(Rio de Janeiro). 
S. carabaya Rothsch. Colour and contours of wings as in arpi, wings somewhat longer than in polybia, 
margin of hindwing less round; the two transverse lines are united either at vein 2 or behind it, the small space 
between them may also be filled with white. Genital organs very different: anal tergit excavated at the apex, 
2 small sharp hooks above the sinus as in polybia , but no dorsal appendage, the long harpe terminates in a 
black pointed hook. South-Eastern Peru. 
So suboclireata Schs. (= bipuncta Dogn.) is not synonymous with polybia, as Rothschild presumed. 
Thorax reddish-brown, abdomen more ochreous. Forewing reddish-brown with a white spot at the base, a 
white dot before the centre of the inner margin, another one above it below vein 2; a triangular violettish-pink 
area at the costal margin; the upper distal apex in the last quarter of the costal margin, parallel to the distal 
margin, extending down to vein 4. Hindwing red-brown, tinged.violettish-red at the inner margin. Colombia. 
So klagesi Rothsch. (136 b) entirely resembles the preceding species, but it lacks the two white dots 
at and above the inner margin. Surinam and British Guiana. 
So adocima Dyar is very similar to hlagesi, the forewing is dark greyish-brown, with a white triangular 
spot at the base, faint traces of a distal line extending from the distal fifth of the costal margin towards the 
inner margin, pronounced at the costal margin by a proximal triangular violet brightening. Abdomen brownish 
ochreous. Panama. 
S. Columbia Schs. (= nisa Drc.). Body yellowish-brown, head and border of collar pink. Forewing 
violettish-pink with a broad, dark-edged, yellowish-brown band from the apex to the centre of the inner margin, 
a small white spot bordered with pink at the cell-end. Hindwing pinkish-brown with pink fringe. Peru. 
S. ocellata Rothsch. (136 b). Brownish orange, tegulae, base, and margin of forewing dusted with lilac 
pink, with the usual 2 oblique lines, between them a white mostly double cellular spot. Hindwing more reddish, 
costal and distal margins lighter. In the nomenclatural form from South-Eastern Peru, the white cellular spot 
is transverse, at least beneath, where the species is separated from the many similar allies by the large black, 
white-centred cellular spot of the forewing; fewer than 20 antennal segments are pectinated, whilst in 
bidens Rothsch., from Venezuela, more than 20 segments are pectinated, the central spot beneath rounded, with 
a round white centre; the dorsal appendage of the anal tergit is longer than in ocellata, the clasper shorter than 
in the latter. 
S. adusfa Rothsch. (136 c). Body above reddish-orange, head and ventrum lighter, more yellowish; 
antemedian line straight, the posterior one almost straight, both brownish black, the median area between them 
orange, base and margin with a reddish-violet hue, in the margin 2 large shadowy spots. Hindwing rounder 
than in jason and nisa, reddish orange as far as the feeble postmedian line, reddish-brown behind it, reddish 
at the cell-apex. South Eastern Peru. 
S. curvilinea Schs. $ above dark brownish ochreous, with a lilac hue at the margin of the forewing, 
a fine dark reddish-brown line from the costal margin near the apex to the centre of the inner margin, from 
where the line rises again almost to the costal margin; a feeble transverse streak at the cell-end. Hindwing 
with a feeble reddish transverse line. In the $ the interior portion of the line is more oblique and parallel to 
the exterior one; hindwing tinged with red. Expanse of wings: $ 68, $ 91 mm. Coatepec, Mexico. Allied with 
jason. — f. boulleti Bouv. chiefly differs from jason in the course of the two transverse lines which meet at the 
inner margin. The specimen lacks the white discal spot which is replaced by a straight streak on the cross-vein. 
Described after 1 $ from Rio de Janeiro. 
S. fallax Bsdv. (136 c). Body and wings orange, marginal area and base dusted with whitish violet 
with 2 reddish-brown transverse lines, the interior one obliquely inwards to the inner margin, the exterior one 
from the apex, distally concave below the centre, with or without a white celullar spot. Hindwing with rust- 
brown hair at the inner margin. Brazil. 
S. marginata Bouv. Allied to jason, the distal margin of the forewing convex. Reddish ochreous, 
tinged with pink behind the distal oblique line; lines blackish-brown, the anterior one straight, the posterior 
one from a little before the apex to the inner margin; a white spot bordered with black-red at the cell-end. 
Hindwing reddish-ochreous, suffused with violet; abdomen pinkish-grey. French Guiana. 
S. jason Bsdv. ( = montezuma Pack.) (136 c, d). Bright orange ochreous, scantily strewn with dark, 
basal area slightly tinged lilac; very feebly so also the extreme margin; lines blackish-brown, the interior one
