large black central spot, and a broad black hind-border con- 

 taining a white blotch. 



Antennae of the male simple, apparently naked, red-brown ; 

 palpi small, horizontal, whitish-brown, red-brown at the tips ; 

 eyes bright chestnut ; head densely but rather smoothly 

 tufted, brownish-drab; thorax smooth, olive-drab, the scales 

 at the back long and rather curved in ; fascicles smoky- 

 white ; abdomen yellowish-brown, thickly dusted with black ; 

 lateral tufts small, anal rather broad, all pale yellow. Fore 

 wings somewhat trigonate ; costa straight to near the tip, 

 where it is a little rounded ; apes bluntly angulated ; hind 

 margin nearly straight, hardly more curved toward the anal 

 angle ; dorsal margin straight or very faintly concave ; colour 

 olive-drab or reddish-drab ; no basal line ; first line scarcely 

 perceptible as a faint angulated thread ; at the middle of the 

 wing is a broad brown transverse band the inner edge of 

 which is sharply defined, the outer expanded in the dorsal 

 area ; second line almost imperceptible, but sometimes trace- 

 able in dots and curves ; outside it is a second transverse 

 brown band, sometimes incomplete, but the costal portion 

 then visible as a brown triangle, its outer edge seems to form 

 the subterminal line ; hind margin faintly dotted with black ; 

 cilia olive-brown. Hind wings rounded, yellowish-white to 

 the middle, except that the ordinary central spot is a large 

 black blotch and extends as a stripe of the same colour along 

 the costal margin to the base of the wing ; beyond the middle 

 is a broad dull black marginal band, near the middle of which 

 is a large yellowish-white spot partly divided by a dark 

 nervure, and near the anal angle another, much smaller ; 

 down the dorsal region is a smoky-black clouding covered by 

 long whitish hair-scales ; cilia yellowish-white. Female quite 

 similar. 



Underside of the fore wings creamy-white, with smoky 

 clouding upon the margins; from the base is a straight black 

 line, above it a round deep black spot ; beyond this another, 

 much larger, followed by a black transverse stripe shading
