S. cadmus H.-S. is very similar to hocleva, the median area more rust-brown, coarsely speckled with cadmus. 
blackish brown, hindwing turning red-brown towards the margin with an indistinct median band; behind the 
exterior oblique line somewhat lighter lilac only towards the apex. Brazil (S. Paulo). A form found in Mexico 
is: - castanea Pack, lacking the discal spot, with rounder hindwings, not red in the distal third. castanea. 
S. verana Schs. (135 d) has broader wings than the two preceding species, variably coloured, but verana. 
generally lighter, fawn-coloured or tawny, the centre of the exterior transverse line slightly convex inwards, 
below the apex slightly outwards, lighter violet behind it, the median area between the lines somewhat darker, 
the white discal dot rather inconspicuous, surrounded by a somewhat darker brown, or absent. Hindwing not 
or but little darker than forewing. Mexico. 
S. intermedia Rothsch. is very closely allied to the following purpurascens and may be a form of it; intermedia. 
the blackish transverse lines are more distinct; the 9 resembles verana -$, the ground-colour is deeper, the lilac 
shading along the lines more distinct. Costa Rica. Genital organs different from those of purpurascens, clasper 
pointed, not truncate or sinuate at the end. 
S. purpurascens Schs. is a magnificent species, dark chestnut-brown with a white discal dot in a black purpuras- 
shadowy spot; 2 blackish lines are edged with pinkish lilac on the averted sides, the most intensely so near 
the inner margin, lighter lilac also subapically. From Guiana to Rio de Janeiro. — imtensiva /. n. (135 d). from intensive,. 
West Colombia, is much brighter and deeper coloured, the pinkish lilac very bright; apex of forewing more pointed. 
Type in the Coll. Niepelt. 
S. pollens Schs. is similarly marked, median area olive brown, basal and marginal areas lilac, transverse pollens. 
lines fine, black, the exterior one from the apex to two thirds of the inner margin; discal dot white. Hindwing 
dark red, costal margin and distal margin, tinged with pink, a large black spot at the cell-end. Costa Rica. 
S. talamanca Schs. as well as the following jacca. are probably merely variable forms of pollens, since talamanca. 
all were taken at the same place and time in March. Body and wings more reddish-brown, scantily and finely 
striated black, hind wing brownish ochreous, only red in the disc and at the inner margin. vilderi Schs. Above vilderi. 
brownish ochreous, thorax lilac; forewing lilac, brownish-ochreous in the median area, with very prominent 
dark lines, the exterior one angled on vein 2 and extending outwards to the inner margin. Costa Rica. 
S. Jacca Schs. has broader wings than pollens , otherwise very much like it. Body light brown, with a jacca. 
lilac tint on the thorax and beneath, the brown fore wing also at the basal and marginal areas; a fine dark line 
extends from the apex behind the centre of the inner margin; a silvery white spot in the lower cell-angle above 
it a white streak. The red hindwing is brownish at the margin. Guatemala (Cayuga). 
S. centrimacula Strd. is described according to 1 $; coloured like the median area of cadmus, but not 
quite so light as in fallax, the marginal and median areas very finely striated black, with a brownish blotch 
on the cross-vein and 2 dark transverse lines, the proximal one vertical to the inner margin, the distal one 
ertending from before the apex to the centre of the inner margin. Hindwing with a faint reddish hue in the 
centre. Ecuador (Macas). 
S. flavosignata Wlcr. (= wardi Bsd., eugenia Drc.) (136 a). Body yellow, thorax in front lilac, abdomen 
with a rusty brownish hue. Forewing of S'- lilac on the yellow ground at the costal margin, in the median area 
and in the upper marginal half, darker yellow in the apical half, densely speckled purple; 2 or 3 oval silvery 
white spots at the cell-end. Hindwing only yellow in a marginal band, otherwise red-brown and dusted with 
violet. The $ is quite violettish-brown with a darker median area, the interior indistinct border concave towards 
the base, the exterior border strongly curved, in the centre concave towards the margin. Mesothorax yellow. 
Colombia, Brazil. Larva green with violet horns and silvery thorns; it lives on Papilionaceae, especially 
thorny Mimosae. 
S. tristygma Bsdv. is very similarly marked, but the basal and marginal reas are reddish lilac, the median 
area orange, the 3 silvery spots as in wardi ; the distal transverse line is almost straight, feebly convex inwards. 
Brazil (S. Paulo). plateada Schs. (136 a) shows a lilac tinge and blackish speckles towards the inner margin plateada. 
in the median area, the distal oblique line is undulate-dentate. Guiana. amazonica Rothsch. resembles amazonica. 
plateada, the black markings are more distinct, the forewing beneath with a large black angidar cellular spot, 
the other forms without it or only with a fine black discal streak. Fonte Boa (Amazons). 
S. polybia Stoll (136 a) has relatively broad wings, orange brown, the median area with a light lilac polybia. 
tinge towards the-costal margin; 2 black transverse lines almost meet at the inner margin, the proximal one is 
flawed on the submedian fold, the distal one from before the apex to the centre of the inner margin, the space 
between both from vein 2 to the inner margin is filled with white. Guiana. - longispina Rothsch. described as longispina. 
a form of it is genitally different, the dorsal appendage of the anal tergit is much longer, the ventral end of the 
clasper with a short obtuse lobe, hook-shaped in polybia. Distal line beneath removed more towards the margin. 
South-Eastern Peru. 
S. janeira Schs. has orange forewings with a purple tinge along the costal margin, and darker grey janeira.
