i62 LEPIDOPTERA. 



and curving toward each other so that an appearance as of 

 solid teeth is produced ; the rows placed nearly on opposite 

 sides and standing well apart ; light chestnut-brown. Palpi 

 covered with long curling red-brown scales ; head strongly 

 tufted with raised yellow scales, a longer tuft at the base 

 of each antenna. Thorax broad, squared, densely covered 

 with upright scales, and beautifully ornamented, the middle 

 portion being of a rich creamy yellow, with a chocolate-red spot 

 in the middle, and edged at the back by two chocolate-red bars 

 which are divided with silvery-white, these two bars being 

 so raised as to form a crest; behind them is a patch of 

 silvery-grey ; shoulder lappets large, each having at its base 

 two chocolate-red cross bars divided by rich yellow ; 

 remainder of the lappets silvery-white. Abdomen long and 

 stout, thickly covered with long creamy-yellow scales, and 

 with a black interrupted stripe down each side ; anal tuft 

 broad and squared, creamy-yellow ; lateral tufts of the same 

 colour forming regular ridges. Fore wings long and ample, 

 broad beyond the middle ; costa almost straight to near the 

 apex, then forming a smooth curve round the apex and hind 

 margin, which last is not very oblique ; dorsal margin almost 

 straight. Ground colour apparently purplish-brown, most 

 visible on the costal region ; but much concealed, especially 

 on the basal and dorsal regions, by silvery-white scales 

 placed in transverse ripples ; first line rather near the base, 

 almost straight, perpendicular, double, purple-black ; second 

 line also double, purple-black, lying far beyond the middle, 

 curved and scalloped, — the hollows outward, — bending 

 suddenly back close to the costa. In a great concave formed 

 by the upper half of this second line, and filling the whole 

 space to the apex, is a very large, round, or ovate, creamy- 

 yellow blotch containing two rows of darker yellow clouds or 

 cloudy spots ; at the end of the discal cell is usually a dark 

 grey streak or cloudy spot, sometimes lying in a creamy- 

 yellow spot or blotch, which, however, is not always per-
