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 1J, 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 

 S. chimeria by the white costal spot before second line.

Male, female. — 14-16J mm. Head and thorax grey-whitish, mixed 

 with ochreous, dark fuscous and black. Palpi 2J, dark fuscous mixed with 

 whitish, basal joint white. Antennas dark fuscous ; ciliations £. Abdomen 

 grey. Legs ochreous white, tibiae and tarsi banded with black. Forewings 

 triangular, costa gently arched, apex rounded, hindmargin distinctly 

 sinuate, oblique ; whitish, irregularly suffused with grey, and irrorated with 

 black ; a short interrupted black streak from base of costa, and a spot on 

 inner margin near base ; first line whitish, ill-defined, curved, hardly 

 indented, posteriorly broadly black-margined, except in middle; orbicular 

 somewhat wedge-shaped, black, touching first line ; claviform similar, 

 but often obscured by dark suffusion ; veins in disc obscurely lined with 

 yellow-ochreous ; reniform 8-shaped, whitish, blackish-margined, connected 

 with costa by a small triangular blackish spot ; second line whitish, slender, 

 indistinct, almost straight, anteriorly black-margined ; terminal space 

 wholly dark, except well-defined subterminal line, which is reduced to a 

 double white subapical spot, and a curved white bar from middle of second 

 line to hindmargin above anal angle, broadly margined above with
