S. coiriputaria Snell. <$, “25 mm" (28 by our reckoning). Antenna shortly ciliated. Wings greyish computaria. 
red, with both cell-dots small, black, that of the forewing with white pupil; lines fine and weak, placed as in 
fuscicosta, the median perhaps more slender. If Snellen has overlooked a dark costal edge, it seems scarcely 
distinguishable except in the “black" vertex (in fuscicosta concolorous with the body). Conejo, Colombia, only 
the type known. 
S. fassli sp. n. (10 c). Forewing rather broad, relatively shorter than most of the species. Ground- jassll. 
colour more purplish than in the preceding, though less so than decorata ; both cell-dots white-pupilled; post¬ 
median line little sinuous, without teeth or sharp dots on the veins. Underside less purplish, the cell-marks 
almost obsolete. Orosi, Costa Rica, 1200 m (A. H. Fassl), a A in British Museum. 
S. dorsiomata Prout, (10 d) is best known by the white abdominal spots and by the double cell-dots, dorsiorna- 
which form — at least on the hindwing—- a black colon-shaped mark. Antennal filiation moderate or rather 
short. Goyaz (town), only the type A known. 
S. mesoturbata Dyar. “28 mm. Light ochreous brown, shaded and powdered with dark rusty brown mesoturba- 
except in the outer half of the median space; inner line dark brown, straight except for a bend at right angles 
on subcosta; discal mark a minute light point in a dark ring; mesial line dark, shaded, dentate on the veins, 
bent inward on submedian; outer line nearly resolved into dots on the veins, bent outward subcostally; veins 
slightly darker outwardly. Hindwing the same except for the inner line; mesial shade just beyond the discal 
mark; space between it and the outer line pale. Cerritos, San Luis Potosi, Mexico, 1 A” Described as an 
Anisodes. 
S, palliata Warr. 35 mm. Pink and lilac grey, crossed by shades of chocolate or purple-brown; the palliata. 
basal area darkened, on the forewing as far as the first line, on the hindwing more extendedly so posteriorly, 
including the silvery white cell-spot and obscuring the transverse shades; cell-spot of forewing vertical, sil¬ 
very white; a fine, dentate submarginal line, with the tips of the teeth darkened. St. Jean de Maroni, 1 $, 
described as a Thysanopyga. 
S. orbifera Prout (10 d). A rather small species, with the A antennal eiliation moderately short. Re- orbifera. 
cognizable by its colour, white vein-dots postmedially and terminally and especially by the very large white 
patches which surround the indistinct cell-rings. St. Jean de Maroni, only the type known. 
S. decorata Dogn. resembles orbifera (10 d) in colour but is not quite so small, has the cell-marks of dorsi- decorata. 
ornata (10 d) and is particularly characterized by its large whitish or pale-yellow terminal spots, placed at apex 
and tornus, the latter the larger, the apical of the hindwing more or less broken. French Guiana (loc. typ.), 
Peru and Bolivia. 
S. didymotoca sp. n. (10 d). A strikingly distinct species, the forevdng shaped nearly as in decorata, didymotoca. 
the ground-colour and the subconfluent pairs of subterminal spots recalling pustulata vivata (p. 80), while the paired 
dark cell-spots associate it with the following group. The antemedian of the forewing is also peculiar, its first 
two spots forming a pair similar to the cell-spots. Matto Grosso (P. Germain), 2 AS in British Museum, ex 
coll. Oberthur. 
S. semibrumiea Warr. (10 d). Unmistakable through the distribution of the two colours, apparently 
not variable. French Guiana and, according to Dyar, Panama. 
semi- 
brunnea. 
S. fulvescens Warr. (= erastus Scleras). Pattern nearly as in semibrunnea (lOd), coloration much more uni- fulvescens. 
form, yellow with red-brown irroration and with only some slight greyish clouding to recall the dark parts 
of that species. French Guiana and spreading to Honduras and to the Amazons. 
S. fusilinea Dogn. “25 mm." Reddish ochraceous, the markings brownish; forewing with cell-mark fusilinea. 
double, nearly united into a line; a fine antemedian, a strong median shade, succeeded distally by an orange 
line; a “second postmedian" beyond, fine and dentate, but incomplete; subterminal less strongly dentate, 
with a terminal irroration between the radials and smaller patches at costa and hindmargin; hindwing with 
a cell-dot, some indistinct lines, and a feeble terminal irroration between the radials. St. Laurent du Maroni.

S. aurata Warr. 25 mm. (English measurement). Readly distinguished from the other yellow species aurata. 
of the genus by the course of the dark lines and by having a grey cloud on anterior half of forewing from 
base to postmedian line; first two lines of forewing very oblique outward from median vein hindwards; 
postmedian and subterminal of both wings strongly zigzag, with long teeth outward on the veins; cell-spots 
white, narrow. Maroni River, 1 A-
