base, above it the finely blackened cross-vein, 3 lilac bands below it. Hindwing yellowish red-brown with 
white fringe. Brazil. 
jucundoides. S. jucundoides Bouv. has somewhat broader forewings than the very similar preceding species; the 
colour is yellowish, the thorax of a purer yellow, abdomen brownish; hindwing light, without any violettish pink, 
very finely striated black; the oblique line extends down below the median and, behind the discal spot, it sends 
a branch to the inner margin, another branch before it to the costa; a small grey spot on the cross-vein. Hind¬ 
wing with a very feeble postmedian line to the centre of the inner-margin. Venezuela (Merida). 
invalida. S. invalida Schs. (137 b). Forewing above dark brown, with a purple tinge, lighter along the distal 
margin; the distal oblique line extends from the apex to the centre of the inner margin and is bordered lighter 
distally; discal dot white. Hindwing dark red with yellow fringe. Thorax and 1st abdominal ring orange red, 
abdomen purple red. Rio de Janeiro. Presumably only a variable form of crocata. 
crocaia. S. erocata Bsclv. (137 c) is a small species like invalida , reddish brownish-yellow, the very narrow' 
brown posterior transverse line extends from the apex towards the centre of the inner margin, but it vanishes 
before, after having formed an obtuse angle inwards below the median. Anterior transverse line quite extinct; 
the white discal spot is very small, the margin with a faint light pinkish lilac tinge. Hindwing not marked. Brazil. 
pamala. S. pamala Schs. (= tricolor Bouv.). Body yellow above, white beneath; tegulae lilac; forewing 
brownish lilac at the base and distal margin, median area yellow at the inner and costal margin towards the 
apex, otherwise lilac with a white discal area broadly bordered with lilac; distal line from the apex to the inner 
margin near the anal angle slightly striated yellow on the inside. Hindwing light yellow, with a slight reddish 
tint at the inner margin. Beneath light yellow, costal and distal margins of forewing lilac. Expanse of wings: 
35—45 mm. Castro, Parana. 
tibialis. S. tibialis Rothsch. (137 c) has the colour of pamala from which it is easily separable by a thorn on the 
anterior and middle tibiae. Antennae with 27 pectinated and 11 plain segments. Body yellowish, collar, margins 
of tegulae, base of abdomen, and ventrum pink. Wings chromatic above, border and inner margin tinged with 
pink, distal oblique line from the apex to 3 / 5 inner margin, distally faded. A small white spot in a pink ring at 
the cell-end. Hindwing quite pink. Paraguay. Length of forewing: 19 mm. 
citrina. S. citrina Schs. Head and thorax light yellow; face and forelegs intermixed with some reddish hairs, 
abdomen white. Forewing light yellow, a fine darker line extends from close below the apex to the inner margin 
close behind the centre; anterior transverse line very indistinct; the small discal spot is whitish. Hindwing 
light yellow, whitish basally. Expanse of wings: 70 mm. British Guiana. 
pelota. S. pelota Schs. Front body yellow, head, collar and tegulae violet. Abdomen red-brown above, white 
beneath. Forewing lilac at the base and marginal area, the latter lighter in the centre; the yellow median area 
striated dark with a large dark lilac shadow at the cell-end and a white cross-vein streak therein. Hindwing 
reddish-brown. French Guiana. 
roseilinea. S. roseilinea Sells, is very different: body and wings white, the latter with a pink basal hue, 2 pink 
transverse lines, the interior one from the costal margin over the cross-vein, then bending inwards, the exterior 
one from near the apex behind the centre of the inner margin. Hindwing with a feeble fine pink postmedian 
line. Costa Rica. 
nettia. S. nettia Schs. (137 c). Mesothorax light yellow, the rest of the front body lilac grey, abdomen light 
red, whitish beneath. Fore wing in the basal third and at the margin purple lilac, turning lilac white towards 
the inner margin, also in the median area above it a large triangular yellow area with its point at the apex, 
enclosing a purple brown shadow with 1 or 2 white dots at the cell-end, the costal margin above it is reddish 
orange, and before it in the cell there is a small orange spot; the border between yellow and marginal lilac is 
undulated, the yellow and lilac areas striated darker. Hindwing yellow, a longitudinal spot before the inner 
margin, as well as the costal margin are purple red. Expanse of wings: 52 mm. South-West Brazil(Joinville); 
Amazons. 
wagneri. S. wagneri Bouv. resembles hemirhodia, but the wings are light yellowish above and beneath, with a 
feeble pink hue basally and in the distal area, the veins somewhat brighter pink; discal spots and transverse 
lines absent except traces of a posterior line proceeding close before the apex and extending straight and in an 
oblique direction to the inner margin. Expanse of wings: 50 mm. Argentina. 
hypoxantha. S.hypoxantha Rothsch. (= flavidorsata Dogn.) (137 d). Collar and abdomen ochreous, thorax and 
ventrum reddish-brown. Forewing narrow, with a long inner margin, reddish-brown, finely speckled black, 
with a very feeble interior line and a broad distinct brown exterior line, a large blackish cellular spot between 
them. Length of forewing: 27 -30 mm. Argentina (Tucuman). 
hemirhodia. S. hemirhodia Rothsch. (137 d). Thorax brown with a purple tinge, abdomen pinkish ochreous. Forewing 
dark brown with a pink tinge, more densely strewn with a darker brown, the marginal area shaded with grey, 
without transverse lines, a small quite indistinct blackish-brown spot at the cell-end. Hindwing yellowish-pink,
