Male. — 28 mm. Forewings moderate, hiudmargin slightly rounded, 

 crenate ; pale greyish-ochreous, irrorated with dark fuscous, forming 

 indistinct irregular stria? ; the suffusion of these forms a rather broad 

 median band, its margins dentate, anterior margin concave, inter- 

 ruptedly white-edged, posterior margin with a short bidentate median pro- 

 jection, white-edged, more strongly and conspicuously on upper half; a 

 black white-circled discal dot ; a dentate white subterminal line, preceded 

 by a dark suffusion. Hindwings moderate, hindmargin somewhat project- 

 ing obtusely in middle, crenulate ; pale grey irrorated with darker ; a 

 median band of four dark grey lines ; hindmargin suffused with dark grey, 

 including a whitish dentate subterminal line. 



Probably constant ; although inconspicuous, not like any other.

 similar lines, often obsolete except on costa ; two dark fuscous lines before 

 middle and three beyond middle, sometimes suffused with grey to form a 

 median band, its anterior edge irregularly concave, posterior edge strongly 

 blackish on upper half, subdentate, with a moderately strong bidentate 

 median projection ; a small blackish discal dot ; three or four indistinct 

 dentate grey lines beyond this, often obsolete except on costa ; cilia barred
