ones, 11 mm. from apex at costal margin, the j)oints of the line uiion the veins 

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

 mnrginal series of minnte dots upon the veins, somewhat nearer tlie postdiscal line 

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



area blackish, except at apical and internal angles. Hindwing bufT, a feeble 



discal line just outside cell, followed immediately by traces of a second line ; a 

 jiostdiseal zigzaj;- line following the curve of the wing, but anteriorly a little farther 

 away from the margin than beliind, distauces at K' and M- being 5 and 4 mm. 

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

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

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



I'lidcrsiJc bnif-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 npperside ; a dentate postdiscal line, 

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

 represented 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 S(!"' and R'. Hindwing : lines situated as above, discal one better 



marked, postdiscal one feebler. 



Eighth tergite (PI. XVIll. f inj shallowly bi-emarginate. Vaginal armatnre 

 peculiar (PI. XVIII. f. 0) ; at each side of the vaginal orifice ( I') there is a high 

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

 (like figure) the horns of an elk to a certain extent; proximally of this armatnre 

 there is at each side a ratlier deep smooth cavity (r) ; the )iostvaginal plate {prp) 

 is feebly chitinised. 



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



Early stages not known.
