(?. Forewing : grey-brown or wood-brown ; the lines slightly darker, ill- 

 expressed, and generally shown more by their paler edging ; costal streak above 

 subcostal vein to submarginal line yellowish straw-colour, the costal half more 

 or less darkened with olive, so that only the subcostal vein shows yellowish ; in 

 the ¥ the subcostal vein is narrowly white, and the wing markings reappear on 

 the costal edge ; before the middle of wing a dark line runs obliquely outwards 

 from costa, is acutely angled in cell, and then runs obliquely inwards to before 

 middle of inner margin, edged by a pale line ; in the c? this line starts from the 

 subcostal streak, which is expanded into a sort of tooth beyond the angle ; 

 snbmarginal line narrow, waved, whitish, or straw-colour, and broader, more 

 diffuse, in the latter case preceded and followed by darker shades ; an outer 

 waved line with pale edge is generally visible at three-fourths, preceded by a 

 dark shade ; and traces of waved lines are more or less discernible in the basal 

 and median areas, marked mainly by dark and light dots on the veins ; cell-spot 

 black, placed close to, sometimes on, the angle of middle line ; marginal line fine, 

 black, interrupted by pale dots at the veins and often with dark dashes between 

 them to the teeth of the submarginal line ; marginal sjiace between veins 3 and 

 4 pale, in the ? whitish. The markings are all plainer in the single ¥ than in 

 any of the c?(?. 



Hind icing : whitish or ochreous- whitish, sometimes dusted with darker ; an 

 inner broadish line, three curved median lines, the outermost thickest, followed 

 by a pale curved band with a dentate line along it; submarginal line distinctly 

 and regularly dentate, followed by a brown marginal shade, and generally also 

 preceded, by a dentate-edged brown band ; fringe of both wings distinctly mottled 

 brown and whitish. 



Underside of forewing whitish suffused with cinereous, of hindwing less 

 suffused ; all the markings expressed in dark grey or brownish fnscous. 



Prothorax and basal half of patagia yellowish straw-colour ; shoulders, vertex, 

 face, and palpi deeper coloured, more ochraceous, even in the ¥ ; metathorax brown ; 

 abdomen in c? yellow, in y brownish grey and white, like the liiudwings. 



Expanse of wings : 26 mm.
