 spot on each side. Palpus with 3rd joint short, ochreous mixed 

 with fuscous. Male antennal pectinations long and reaching to 

 near apex — beyond three-fourths (female without head ). Vertex, 

 thorax, and abdomen concolorons with wings, abdomen with a 

 dark fuscous doi-sal blotch anteriorly. Fore wing narrow, costa 

 and termen almost sti-aight, hind margin somewhat convex, in

 (sometimes leather long-stalked) ; pale ochreous whitish, irrorated 

 and suffused, especially at base and half-way nlong costa, with 

 purple-grey ; a brown or fuscous stripe fi^om beyond middle of 

 costa, oblique outwards, strongly curved or angled between R^ 

 and R', oblique inwards (and forming a A^ery slight proximal 

 curve) to middle of hind margin ; a faint, oblique antemedian line 

 or shiide usually indicated, another midway betAveen postmedian 

 and termen, bearing in its anterior part two or three darker 

 wedge-shaped spots, the one before R^ the strongest and blackest ; 

 fringe spotted with fuscous. Hind wing nan'ow, especially in
