base of costa, interrupted by a white mark; first line white, tolerably 
distinct, hardly indented, near inner margin bent more obliquely outwards, 
posteriorly narrowly black-margined ; a large quadrilateral blotch on costa 
suffused with dark fuscous, bounded anteriorly by first line, beneath by 
submedian fold, posteriorly by a straight line passing through anterior edge 
of reniform parallel to hindmargin ; orbicular small, round, black, claviform 
elongate-oval, black, both tolerably detached but obscured by dark suffu- 
sion; reniform 8-shaped, clear white, black-margined, incompletely beneath; 
a cloudy white subquadrate costal spot before second line, touching reni- 
form, and space between reniform and second line generally white mixed 
with grey; second line white, distinct, anteriorly blackish-margined ; 
_ terminal space suffused with dark fuscous except towards anal angle; sub- 
terminal line broad, interrupted, lower portion white, edged with pale 
ochreous above, almost touching second line, upper portion clear whitish- 
ochreous; an irregular white hindmarginal line: cilia pale whitish- 
ochreous, with a dark fuscous interrupted and posterior grey line, Hind- 
wings 14, very pale whitish-grey, postmedian line and hindmargin obscurely 
darker; cilia whitish, with basal row of cloudy grey spots. 
Characterized by the concentration of the dark suffusion into a costal 
blotch ; differing from S. minusculalis by the distinct white first line, from 
B. chimeria by the white costal spot before second line. i
