TRIFID^. 27 



Autennfe of the male notched with short pointed teeth, 

 which are tipped with fine bristles and thickly ciliated ; 

 palpi rather horizontal, broadly tufted to the tips, pale 

 brown ; head densely scaled, yellowish-white ; at the base 

 of each antenna is a small tuft of scales ; thorax fluffy, 

 pale yellow-brown ; collar and bases of the top and back 

 crests nearly white, the back one tipped with fulvous ; 

 shoulder lappets dotted with deeper brown, and edged with 

 yellowish-white ; fascicles white ; abdomen pale drab, abun- 

 dantly covered at the base with whiter hair-scales ; on the 

 dorsal ridge are four or five slender crests tipped with brown ; 

 lateral tufts spreading ; anal tuft not very large. Fore wings 

 of moderate breadth ; costa very straight ; apex bluntly 

 angulated ; hind margin gracefully curved and rather filled 

 out ; dorsal margin straight to near the base, then well 

 rounded in ; colour pale fawn or yellow-brown, shaded with 

 white ; basal line only suggested by a dark-brown dot 

 edged outwardly with white, situated at the base of the costa ; 

 first line broad, direct, yet repeatedly angulated, white and 

 conspicuous, partially edged outside with black atoms, the 

 portion nearest the costa forming a crescent, and followed at 

 a short distance by a similar crescent of black atoms, which 

 joins a central cloud of rich brown and black dusting across 

 the middle of the wing ; this is broken above the dorsal margin 

 by a white bar, which unites the first and second lines ; the 

 latter line is white, curved, but formed into a series of white 

 crescents, with rather long points, and spread into white 

 clouds ; subterminal line cloudy white, waved and irregular, 

 but with a faint central white W, which is short and obscure; 

 the space between this and the second line is crossed by a 

 single black streak ; orbicular stigma very small, round, 

 yellow-brown, edged with black-brown ; the space closely 

 following it also partially edged with black ; reniform stigma 

 very large, white, shaded with yellow-brown, and coalescing 

 with the second line — indeed it has no definite margin — clavi- 

 iorm stigma edged or clouded with black atoms ; on the costa
