 niarked liy tiny dots, except on M- and SM-, where the dots are isolated ; a sub- 

 inari^^inal series of minute dots upon the veins, somevvliat nearer the postdiscal line 

 than the outer margin, last two dots placed in a small blackish cloud ; marginal 



area blackish, except at apical and internal angles. Ilindwing bufi", a feeble 



discal line just outside cell, ft)llowed immediately by traces of a second line ; a 

 postdiscal zigzag line following the curve of the wing, but anteriorly a little farther 

 away from tiie margin tlian beiiind, distances at K' and M- being 5 and 4 mm. 

 respectively, a submarginal series of dots joined to one another by black scales, 

 edge of wing also black, marginal area down to postdiscal line densely powdered 

 with black scales, abdominal fold and anal angle more grey tluin disc. 



Uiakrside but!-colour, speckled with black scales (excejit basal half of forewing), 



outer area of forewing and abdominal area of hindwing greyish. Forewing: no 



lines in basal half : three rather broad but not heavily marked discal lines, dentate, 

 obsolete behind, a little more distal than on upperside ; a dentate postdiscal line, 

 feeble, marked with dots upon the veins ; the vestige of a submarginal line, 

 rei)resented at costal margin by a thin line and upon the veins by more or less 

 obsolete dots ; with this line is fused a black curved streak running from apex of 



wing across RC'' and 11'. Hindwing: lines situated as above, discal one better 



marked, postdiscal one feebler. 



Eighth tergite (PI. XVJII. f. lo) shailowly bi-emarginate. Vaginal armature 

 l)eculiar (PI. XVIII. f. D) ; at each side of the vaginal orifice ( V) there is a high 

 ridge produced into prominent teeth, the armature resembling in a ventral asjiect 

 (like iigure) the horns of an elk to a certain extent; proximally of tliis armature 

 there is at each side a rather deep smootli cavity (<■) ; the j>ostvaginal plate {jirp) 

 is feebly chitinised. 



Length of forewing : 41 mm.; breadtli, 17 mm. 



Early stages not known.
