6 i and 4 9 . — The outer edge of the fore wings is not excavated, and hind 

 wings not angulated ; it differs from all the other species known to me by 

 the distinct, dark, clear sigmoid line crossing the outer third of both pairs of 

 wings. Body and wings tawny-ash, head a little darker than the body; front 

 of head, palpi, and antennae tawny-yellow. Fore wings densely speckled 

 with brown, with four prominent brown spots on eosta ; the two inner being 

 the termini of an indistinct row of venular dark dots, the .second including 

 the discal dot. The third line represented by a distinct s-shaped wavy black 

 line, sometimes, but not visually, reaching the costal dot. Beyond is a broad 

 dark shade running across the wing. Half-way between the sinuate line and 

 the edge of the wing is a white interrupted line. The usual black points on 

 the edge of the wing. Hind wings (usually) with a single sinuate distinct 

 brown line crossing the wing; beyond, a broad brown shade, succeeded by 

 an irregular whitish line often obsolete. Beneath with an ochreous tinge; 

 densely speckled ; the line faintly reproduced. Subniarginal broad band dis- 

 tinct ; discal dot (in hind wing large ; on fore wing it is indistinct.
