sinuate, very oblique ; pale fuscous, irrorated with darker ; a small blackish 

 spot at base of inner margin ; a straight rather irregular black streak from 

 base to somewhat before middle of disc, almost meeting a triangular 

 blackish blotch, of which the apex is directed downwards, placed in disc 

 beyond middle, its posterior side bounded by second line ; dorsal half of 

 wing below these black markings wholly white, sharply defined above, 

 slightly suffused with greyish beneath ; first line faintly indicated by 

 angulated darker posterior margin ; two short oblique cloudy dark fuscous 

 streaks in disc, terminating in triangular blotch ; second line white, indis- 

 tinct towards costa, obsolete in dorsal suffusion, rectilinear, very obtusely 

 angulated above middle, very slightly sinuate near costa ; upper half of 

 subterminal line forming a whitish triangular blotch, suffusedly margined 

 beneath with black, apex touching angle of second line, lower half merged 

 in dorsal suffusion ; a hindmarginal row of black dots : cilia whitish, with 

 two grey lines. Hindwings 1^, grey-whitish, hindmargin faintly suffused 

 with darker ; cilia white, with a grey line. 



Nearly allied to S. exilis, but easily distinguished by the smaller size, 

 well-defined white dorsal suffusion, strong black streak from base, black 

 triangular blotch beyond middle, straighter second line, and black triangu- 

 lar spot on middle of hindmargin. 



Castle Hill, amongst grass in a swampy place at 2,500 feet, flying freely 

 towards dusk, in January ; common.

 fuscous, with a white anterior spot. Abdomen whitish-grey, segmental

 large, elongate, black, conspicuous ; reniform obsolete on upper half, lower 

 half round, white, partially finely black-margined ; second line tolerably 

 distinct, white, anteriorly irregularly blackish-margined except towards 

 inner margin, angularly indented beneath costa, very shortly angulated 

 above middle, slightly indented near inner margin ; subterminal broad, 

 cloudy, white, not interrupted, almost touching second line ; a hindmarginal 

 row of cloudy almost confluent blackish dots ; cilia white, with two dark
