C YMA TOPHORID.^. 205 



stout, fore wings narrow, whitish, with two straight purplish- 

 brown transverse stripes ; hind wings whitish. 



Antennae notched, ciliated, brownish, head and palpi 

 strongly tufted, grey ; eyes naked, with a few blackish 

 lashes at the back ; thorax moderately broad, covered with 

 uplifted grey scales ; shoulder lappets raised and prominently 

 tufted at the corners; the long scales of the middle of the 

 back drawn together behind into a slight tuft or crest ; 

 following this, from the back of the thorax, long tufts or 

 fascicles of white hair-scales spread over the base of the 

 abdomen, which is shining greyish-white, and has on its third 

 segment a conspicuous oblique blackish dorsal crest, or tuft, 

 of semi-erect scales. This crest is in some specimens absent, 

 while in others there is a small additional tuft on the previous 

 segment ; lateral tufts distinct, whitish ; anal tuft narrow. 

 Fore wings rather narrow, costa very slightly rounded 

 throughout ; apex sharply angulated, and hind margin below 

 it slightly hollowed, then gracefully curved off to the dorsal 

 margin, which is very straight ; colour greyish-white, faintly 

 tinged with brown ; two broad, almost straight, purple-brown 

 stripes cross the wing and are very conspicuous, the first, 

 before the middle, is edged outwardly by the normal first 

 line, which is black and rather undulating ; just beyond the 

 middle is the second line, also black and much waved, forming 

 the inner edge of the second stripe ; beyond this the hind 

 marginal space is very pale purplish-grey, with two rippled 

 paler transverse lines, and the nervures slenderly streaked 

 with black, as also are the costal and hind margins ; cilia 

 greyish-white. Hind wings rather short, rounded, white, 

 with two broad greyish transverse stripes, one in the middle, 

 the other along the margin ; cilia whitish. Female with abdo- 

 men rather stouter and more pointed, otherwise quite similar. 



Underside of all the wings white, shining, each with an 

 indistinct central cloudy transverse stripe or band, followed 

 by a fainter and more slender cloudy stripe; body and legs" 

 whitish.
