pink. We figure this couple. I presume that walkeri Grt. about which I could not ascertain any further particulars 
is the same, in which case that name would have to be preferred. 
S. rorerae Schs. $ orange ochreous on the body above, abdomen with small black lateral spots in the 
basal half, under surface purple pink. F ore wing orange ochreous, basal and marginal areas suffused with light 
greyish pink, strewn with neutral grey behind the cell and in the marginal area; the brown transverse lines are 
finely undulate-dentate, the anterior one excurved, the posterior one from near the apex incurved to the centre 
of the inner margin; 2 small white spots at the cell-end. Hindwing orange ochreous with a dark line from the 
apex to the centre of the inner margin, marginal area suffused with light greyish pink. The $ is monotonously 
cinnamon reddish, more densely striated dark, light pinkish-grey only at the anal angle of the forewing and 
in the marginal area of the hindwing. Expanse of wings: 39, $ 56 mm. Macas and Guayaquil, Ecuador. 
S. heiligbrodti Harvey (137 e) has light grey forewings finely strewn with dark, the posterior one of the 
two brownish-grey transverse lines is strongly undulate-dentate, the anterior one introangular on the median, 
a white dot in a grey shadow at the cell-end. Disc of hindwing pinkish carmine with a black central dot. and 
with a light grey border. Abdomen pinkish subdorsally. — hubbardi Dyar is a much darker stone-grey form. 
Arizona. 
S. albolineata G. A R. (= raspa Bsclv.) (137 f). The grey ground-colour of the forewing is densely 
scaled yellow in a variable intensity, with 2 white transverse lines, the interior one from close behind the first 
third of the costal margin, bent towards the base on the inner-marginal vein, the exterior one from the apex 
to the centre of the inner margin, with or without a white central dot between them, the veins more or less 
dusted with white, especially in the median area; the two transverse lines may intersect on vein 2, especially 
in the Hindwing carmine with a black central dot and a white bent postmedian line and white fringe. 
Mexico; also reported from Arizona. 
S. formosa Dogn. (= bilineata Giac. nec Burra.) resembles the following species; front body white, 
the 6 first abdominal rings pinkish ochreous above. Forewing white, scantily striated brown with 2 longitudinal 
lines, a dark brown one with a leaden lustre along the costal margin, the costa itself reddish ochreous, the 
second red-brown along the median, the veins around it pink. Hindwing pinkish brown or light brown with 
pink veins and white fringe. The $ is double its size, abdomen white with a carmine transverse line. Argentina 
(Rio Salado). f. inverso-atomosa Giac. is densely covered with greyish-black striae. La Rioja (Argentina). - 
inversa Giac. (137 f), considered a species by the author, I believe to be merely a form having developed from 
inverso-atomosa , the whole surface of the wings having turned blackish-grey except a white longitudinal band 
through the cell, the costal margin itself being finely carmine. Hind wing white, smoky at the margin. 1 
from La Rioja. — inverso-atomosa Giac. (137 f) of the latter form exhibits the blackish-grey ground-colour 
tinged somewhat more reddish, and deeper black striae dispersed across the white and dark colour; the veins 
on the forewing are prominently reddish. Likewise from La Rioja. 
S. bilineata Burm. is white, the abdomen above with a feeble pink hue. Fore wing with a fine blackish- 
brown line below the costa, and another somewhat broader one below the median extending to the distal margin 
right below the apex in a slight proximal bow. Hindwing white. Argentina. 
S« floresi Giac. being unknown to me is probably also merely a form of one of the two preceding species. 
In the brief description it is placed beside bilineata. Forewing whitish-grey, feebly tinged with pink and strewn 
with grey; the dark longitudinal line has the same shape as in bilineata and extends from the base to the apex 
in a slight bow. Argentina. 
S. cinerea Schs. (142 d). G with long and narrow forewings, with a rounded inner margin; hindwing 
with a produced anal angle. Fore wing grey, median area more brownish-grey, the broad dark lines undulate- 
dentate, the interior one vertical, the exterior one from near the apex to the inner margin near the anal angle; 
with or without a large white spot at the cell-end. Hindwing grey at the distal margin and anal angle, the rest 
more brown, the inner margin almost black. Abdomen golden brown with lighter rings. Rio de Janeiro. 
S. lilacina Schs. (= affinis Rothsch.) exactly resembles the Brazilian cinerea , the light margin is broader, 
the genitals very different; the anal tergit terminates in a short sharp hook. It may be the northern representative 
of cinerea in Venezuela, the Guianas, Amazons, and Peru, but the genitals are rather too different; the nomen- 
clatural type has a more ochreous collar and rounder hindwings, whilst the $ shows the marginal area in both 
wings only half as broad as in photophila Rothsch. (142 d), from Surinam and the Amazons. Here the margin 
of the hindwing is straight or even somewhat concave, the mesothorax somewhat less yellow; ground-colour 
more pinkish-brown or also olive, forewing without or with a white cellular spot which may also be double, 
as in the specimen figured from the Berlin Museum from S. Paulo de Olivenpa. The $ is darker, the body 
less bright ochreous. 
S. surrotunda Dyar (142 e) may also be merely the northernmost representative of cinerea, from Mexico. 
Wings much rounder, distinctly pinkish-brown, the lighter marginal area broad, the transverse lines bordering 
on the darkened median area much less distinct and scarcely dentate. Mesothorax scarcely yellow, the blackish 
abdomen with narrow ochreous rings. West Mexico (Colima).
