round the antennas, from the base of each of which projects a 

 very small pointed whitish tuft, the rest pale brown tipped 

 with red-brown ; collar rather large, divided in the middle, 

 ashy-white tinged in the middle with fulvous, and edged at 

 the back with tawny-brown ; shoulder-lappets reddish- white 

 edged with white, and with a few red-brown dots ; remainder 

 of the thorax raised into red-black top and back crests which 

 are frosted with white ; fascicles white ; abdomen not very 

 long, reddish-drab, thickly covered at the base with white 

 hair-scales, and having on the dorsal ridge two black crests 

 tipped with white ; lateral tufts small ; anal tuft contracted. 

 Fore wings narrow, rather constricted behind ; costa very 

 faintly arched at the base and much more so near the apex, 

 which is pointed ; hind margin shortly curved, rather con- 

 tracted, scalloped, crenulated, and flatly excavated close to 

 the anal angle ; dorsal margin rather concave ; colour whitish- 

 brown or whitish-drab, shaded with dull reddish-umbreous ; 

 costal region broadly blackish-umbreous frosted from base to 

 apex with grey ; on the dorsal margin is a narrow red-black

 brown ; second line indicated by the two crescents of white, 

 backed with black, on the dorsal margin, but above these

 or four similar dots lie above the median nervure, but beyond 

 this the ordinary pattern of markings is not present ; beneath 

 the costal stripe, toward the hind margin, are three or four 

 tawny streaks lying between nervures, and on the costa two 

 or three steel-grey dots ; extreme hind margin edged with an 

 undulating pale brown line ; cilia purplish-white, intersected 

 by a series of pale brown streaks interrupted by white dashes, 

 the cilia also extended along the dorsal margin, shading from
