vertical to the inner margin, the exterior one from before the apex, a very small white dot in the lower cell- 
angle, absent in the $. Inner margin of hind wing with darker red hair. Mexico to Colombia and Brazil. 
S. subangulata H.-S. (= obscura Bouv.). Thorax pinkish greyish-brown, abdomen smoke-brown; subangulata. 
forewing in the median area coloured like the thorax, basal and marginal areas darker brown, with a slight 
pink tinge; anterior transverse line almost straight, at the costal margin more remote from the base than at the 
inner margin, the exterior oblique line very obliquely from the apex to the centre of the inner margin, very 
slightly convex inwards; discal spot darker. Hindwing with a feeble transverse line, tinged pink. Beneath 
the disc of the forewing is red, the black spot not centred white. Mexico to Brazil. Larva dark green with a 
blue head and lateral stripe, with silvery thorns on the middle segments, the thorns on the 2nd and 3rd rings 
very long, dentate, black. It lives on a thorny creeper. 
S. acuta Schs. (136 b) has a pinkish-brown body. Forewing very pointed, reddish-brown, dusted with acuta. 
lilac basally and at the margin, the interior line from the centre of the costal margin to the interior third of the 
inner margin, the exterior line from the apex to % inner margin, an indistinct grey, white-centred spot at the 
cell-end. Hind wing reddish-brown, with red hair at the inner margin. Beneath orange with a large grey 
marginal triangle and a large black, white-centred spot at the cell-end. Venezuela (Aroa); West Colombia. 
S. catoxantha Bothsch. is larger than subangulata, the forewing more pointed, the oblique lines more catoxantha. 
prominent, beneath yellow instead of red; lighter and smaller than acuta, hindwing above only with a red spot; 
instead of being quite red, the black cellular spot of the forewing beneath is centred white. Venezuela, South- 
Eastern Peru. 
S. lacrimata Dogn. is somewhat smaller but otherwise very similar to catoxantha, at the cell-end of the lacrimafa. 
hindwing above there is a very large, distinct, lachrymiform black spot the pointed end of which is directed 
upwards; median area of forewing above pinkish-grey, hindwing beneath quite pink without the ochreous 
dusting like catoxantha. Amazons. 
S. irrorata (= irrorta Schs. ex err.) (135 e) is light reddish-brown in the <$, feebly strewn with lilac, the irromta. 
narrow basal area, the distal margin behind the line and a large round discal spot are lilac; interior line indistinct, 
very near to the base, the fine distal line lilac, from the apex slightly curved to % inner margin. Hindwing 
pink, costal and distal margins with a light brown hue. Beneath basally and in the disc pink, costal margin 
yellowish-brown, distal margin lilac, the line red, a large black discal spot before it. In the $ the brown forewing 
is more densely striated black and lilac, the discal spot hardly visible, the fine dark distal line straighter than 
in the <$. Expanse of wings: 58, $ 79 mm. Mexico (Jalapa, Orizaba). 
S. yucatana Drc. Body and forewing yellowish-brown, forewing densely strewn with dark brown, the yucatana. 
brown oblique lines feeble, an indistinct brown spot at the cell-end. Hindwing rosy red, yellow at the distal 
margin. Beneath without lines, with a large black spot on the forewing. Yucatan. 
S. carisma Schs. is reddish-ochreous on the front body, the tegulae inside bordered with dark grey, carisma. 
abdomen tinged lilac laterally and beneath. Fore wing reddish ochreous, strewn darker, inner margin fine lilac 
grey; the fine dark antemedian line straight, the posterior transverse line extends from near the apex to the 
centre of the inner margin, distal margin tinged lilac, the white discal spot surrounded by dark, a dark dot 
above it; hindwing red-haired at the inner margin, apex slightly dusted with dark. The $ is browner, more 
intensely strewn with black, with 2 small black discal dots, Hindwing reddish with a dark transverse line 
through the centre. Expanse of wings: 63, $ 96 mm. British Guiana. 
S. guianensis Bouv. is very closely allied to jason by its shape and colour, but it differs from it in 2 guianensis. 
small white discal spots and in the absence of the black discal spot on the forewing beneath; distal margin 
quite straight, the veins not prominent in the distal portion; the inner margin of the hindwing lacks the dark 
red-brown spot; distal portion of forewing dusted with pinkish-grey. A smaller species with an expanse of 
57 mm. French Guiana. 
S. brevis Wkr. ( — convergens H.-S.) (135 e). Reddish-brown, with a feeble lilac tinge, black veins, brevis. 
2 transverse lines convergent towards the inner margin, the distal one lighter inwards, a short feeble streak 
at the cross-vein; separated from anthonilis by shorter and broader wings. Brazil. Larva very similar to that 
of subangulata, yellowish-green with golden thorns, and living on Mimosa. 
S. lanaris Rothsch. Shape and colour very similar to brevis, antennae with 16 pectinated segments; lanaris. 
forewing less long, margin broader, the distal oblique line thinner, proximad more distinctly bordered with 
grey. Hindwing rounder, particularly analwards, the reddish spot smaller. Forewing beneath loam-coloured 
not ochreous towards the inner margin. Genitals very different. Bahia. 
S. anthonilis H.-S. is more greyish-brown, the distal oblique line very broadly bordered with greyish- anthonilis. 
white inwards. Hindwing with a slightly curved brown postdiscal line. Brazil. — analis Bothsch. (135 e) has analis. 
somewhat broader forewings, the two lines are more sej)arated, the distal one more remote from the cell. 
Clasper-wool ochreous. South-Eastern Peru. Southern Colombia. The black larva with reverted thorns lives 
on various foliage-trees in 2 generations.
