618 REVISION OF AUSTRALIAN LEPIDOPTERA, 



gently curved, nearly followed by a very indistinct grey parallel 

 shade, and usually marked in middle with a small blackish spot 

 or a short longitudinal line extending to hind margin; subterminal 

 whitish, very obscure, subdentate, grey-margined, forming a small 

 dark spot on anterior edge above middle ; a hindmarginal series 

 of black dots, connected by a fine line. Hind wings with hind- 

 margin gently rounded, dentate ; colour and markings as in 

 forewings, but first line absent, median shade stronger, nearly 

 straight, second line more strongly marked on lower half, nearly 

 followed by a more or less distinct brownish-ochreous parallel 

 shade, without blackish spot in middle. 



Newcastle, New South Wales ; Geraldton, West Australia ; in 

 November, eight specimens. This and the two following species 

 differ from the rest in the discal transverse spot of raised scales ; 

 S. acaciaria is smaller than the other two, and distinguishable 

 from both by the well-marked black bar of face. This species 

 occurs also in India, Ceylon, South Africa, and probably the 

 adjoining islands ; there is a tendency to the origination of slight 

 local forms, and the Australian form thus inclines to show the 

 ochreous or brownish tinge of some markings more distinctly, but 

 I can see no more reliable point of distinction.

(JQ. 40-41 mm. Face densely rough-scaled, fuscous-whitish, 

 with indications of a blackish median bar. Antennae in g with 

 apical f simple. Forewings with hindmargin obliquely rounded, 

 waved; 10 and 11 separate; whitish-ochreous, clouded with pale 

 reddish-ochreous ; first line black, rather irregular, curved, nearly 

 preceded by a fuscous-reddish parallel shade sometimes wholly 

 suffused with black; a moderately large white discal spot, including 

 a transverse ridge of raised scales, in 9 suffused with fuscous, 

 placed on median shade, which is slender, fuscous, rather irregular, 

 tending to form a blackish spot on costa ; second line black, sub- 

 dentate, upper half unevenly curved, nearly followed by a fuscous- 

 reddish or blackish parallel shade, becoming broadly suffused with
