TRIFID^. 267 



covered with white hair-scales and without dorsal crests ; 

 lateral and anal tufts small, white. Fore wings somewhat 

 triangular, narrow at the base and gradually increasing in 

 width ; costal margin very straight ; apex bluntly angulated ; 

 hind margin very faintly crenulated, regularly curved and 

 but little oblique, except when approaching the anal angle ; 

 dorsal margin rather broadly fringed with oblique white 

 scales and rolled back so that these scales are partially erect ; 

 colour deep rich smooth umbreous, streaked and barred with 

 black ; basal line abbreviated to two black spots or streaks 

 edged inwardly with yellowish white ; first line straight, very 

 little oblique, broadly white, edged on each side with a 

 slender black line and sometimes divided by a faint brown 

 shade ; second line much curved and strongly angled, broadly 

 white or pale brown, divided throughout by a browner thread, 

 edged inwardly by black crescents, but outwardly throwing 

 off long brownish-white conical streaks to the subterminal 

 line, the spaces between these being occupied by long black 

 wedge-shaped streaks, subterminal line a broad white evenly 

 curved stripe lying along the hind margin and giving an 

 aspect of peculiar neatness and definite outline to this species ; 

 between the first and second lines the nervures are con- 

 spicuously white and the subcostal throws off white blotches 

 to the costal margin ; orbicular stigma white, faintly clouded 

 with brown and edged with black ; reniform stigma 

 conspicuously white, edged with black and containing two 

 perpendicular fawn-coloured streaks — this stigma and the 

 dorsal portion of the broad white second line seem to form a 

 broad perpendicular interrupted white band crossing the 

 wing — costa beyond the middle regularly dotted with white ; 

 dorsal margin pure white ; extreme hind margin edged with 

 minute black-brown crescents ; cilia very long, the basal 

 half pale brown clouded with darker, the outer half white 

 shaded with pale brown, the whole divided by whiter dashes. 

 Hind wings broad, rounded, white, with a faintly brown 

 central lunule, followed by a rather darker brown slender
