C YMA TOPHORIDM. 1 99 



Antennge simple, faintly ciliated, pale yellowish-brown; eyes 

 naked; palpi tufted, rather projecting; head mottled with grey 

 and black ; thorax stout ; collar sharply defined, mixed black 

 and pale grey ; shoulders very prominent, and the lappets up- 

 lifted and covered with long grey, greenish-grey, or purplish- 

 grey scales ; rest of thorax similar, the scales forming a very 

 obscure tuft or crest at the back ; fascicles broad, whitish, 

 meeting over the abdomen, which is stout, greyish- white, 

 with minute whiter lateral tufts, and a contracted anal tuft, 

 also with a central dorsal ridge, on which are sometimes visible 

 minute tufts of half-raised scales. Fore wings moderately 

 broad ; costa nearly straight ; apex bluntly angulated ; hind 

 margin very slightly curved, but more so toward the anal 

 angle; dorsal margin also gently rounded; colour pale pinkish- 

 grey or purplish-grey, with a distinct, black, interrupted and 

 angulated basal line, followed at a short distance by a broad 

 transverse band, composed of four rippled black lines, which 

 rather diverge at the dorsal margin ; of these the first is thick 

 and deep black, the fourth equally conspicuous and more 

 notched ; beyond the middle is a second transverse band, 

 more oblique and formed of three or four repeatedly- angled 

 black lines ; halfway from this to the hind margin is a rippled 

 whitish line, edged outwardly with blackish points, from one 

 of which a black line runs to the apex of the wing ; between 

 the two broad bands are the two stigmata, the orbicular 

 round and indistinct, the reniform rather squared and divided, 

 both whitish or ashy-white ; hind margin edged with faint 

 black dashes ; cilia brownish. Hind wings rather elongated, 

 with the hind margin sinuous ; colour pale greyish -brown, 

 with a faint paler transverse stripe in the middle. Female 

 with the abdomen very stout and short, almost devoid of 

 tufts, anal segment shortly pointed, otherwise similar. 



Underside pale smoky-grey, with faint indications of a 

 darker central spot, and two darker transverse stripes beyond 

 the middle ; body and legs smoky-grey. 



Yariation in this species seems to be mainly climatal. In
