densely striated black, less so at the distal margin, without traces of transverse lines. Hindwing light brown,

S. vinacea Rothsch. (137 d). Anterior body reddish ochreous brown, abdomen claret-coloured; forewing vinacea. 
brownish claret-coloured basally and in the marginal area, reddish ochreous in the median area, towards the 
costal margin almost to the apex; no transverse lines, the whole wing feebly strewn with blackish-brown, no

S. approximate Schs. is similar to vinacea ; body purple above, thorax and base of abdomen ochreous, approxi-

S. leucantha Bsd. has the size of brevis ; forewing light cinnamon reddish, base and marginal third leucantha. 
whitish pinkish grey, defined by oblique, scarcely darker lines which are often absent, a brown dot at the cell-end. 
Hindwing the same, with red hair at the inner margin; body coloured like the wings. - - Larva green with 
white small thorns showing black ends and being thicker and somewhat dentate on the 2nd, 3rd and penultimate 
segments. Brazil.

ochreous, finely strewn with dark; basal area lilac as far as the subcostally angled anterior transverse line; 
a round brown spot at the cell-end; the fine brown distal oblique line from the apex slightly sinuate to the inner 
margin behind the centre, the marginal area behind it is darkened. Hindwing reddish ochreous, broadly red 
at the inner margin as far as behind the centre. The $ is more densely strewn, the cellular spot indistinct, 
hindwing darker. Expanse of wings: £ 56, $ 62 mm. Costa Rica. 
S. argyracanfha Bsclv. (137 d). Body red-brown, tegulae bordered with lilac grey; forewing red-brown, argyra- 
striated black, dusted with lilac towards the margin, the border between the two colours extends obliquely cantha. 
from before the apex to the distal third of the inner margin, very concave distally in the lower half. Hindwing 
copper-brown. Brazil. The yellowish-green larva exhibits thorns similar to polished silver and reverted 
denticulate horns. On Gleditschia. 
S. oda Schs. Head white, front body reddish-brown, abdomen dark purple lilac above, white beneath, oda. 
Fore wing narrow, from 5 rounded to the centre of the inner margin; hindwing long, slightly angled on 5. 
Forewing dark brown in the basal half with a long reddish brown cell-end spot, lighter brown distally, finely 
strewn with black, especially at the inner margin, dusted lilac at the distal margin. Hindwing brown, distal 
margin narrowly dark lilac below 5, with a white basal spot; fringe white. Expanse of wings: 41 mm. French 
Guiana. 
S. crispula Dogn. resembles crocata, it has more elongated forewings which are marked the same crispula. 
otherwise, but the discal dot is brown and not white. Colour very variable; saffron-coloured, rusty yellow, 
yellowish brown or violet, always striated brown, partly unicoloured, partly lighter in the inner-marginal 
halves of both wings; the fine brown transverse lines are partly scarcely indicated, the anterior one distally 
somewhat convex, the posterior line from close before the apex to the inner margin almost at the anterior 
one; the discal dot has almost vanished in the ground-colour. Body like wings. Expanse of wings: 39 
to 43, $$ 45—52 mm. Argentina (Tucuman). 
S. rubicunda F. (= venusta Wlcr.) (137 e). <$ rosy red above at the base and margin, median area and rubicunda. 
body light yellow, hindwing much paler. In the larger $ the pink basal and marginal portions are broadly 
confluent in the inner-marginal half. Hindwing almost white. - alba Grt. (= pallida Bowles ) is much lighter, alba. 
almost white. The larva has a red head and a light green body granulated white, with 7 darker green longitudinal 
stripes and a cerise lateral stripe on the 3 last rings; the horns are shorter than in the other species, whitish, 
black at the ends. On maple, more rarely on oak. Atlantic States. 
S. apollinairei Dogn. (137 e) is coloured and marked somewhat like rubicunda F., but the colours are apollinairei. 
brighter yellow and pinkish carmine. Body yellow, tegulae, legs and ventrum pink. Forewing from the base 
narrowed at the costal margin to the apex, the distal margin broadly and the inner margin pinkish carmine, 
the rest of the disc yellow. Hindwing yellow, costal and distal margin finely pink. Described after a $ from 
Colombia (Villavicencio). A couple evidently belonging to this species, from Rio Grande do Sul, e Coll. Stgr. 
(Berlin Museum), shows the red peach-blossom colour still more extensive, the $ is quite unicoloured bright
