TRIFID^E. 1/5 



olive-brown, with a squared white blotch toward the apex 

 and a white cloud at the anal angle. Hind wings white 

 with a broad black marginal band. 



Antennas of the male nearly naked, simple, whitish-brown ; 

 palpi, head, and thorax pure white, the latter stouter than in 

 the last species and having the scales at the back slightly 

 raised into a flattened shelf-like crest ; abdomen silvery- 

 white with a dull smoky-brown anal tuft. Fore wings 

 rather trigonate, not very broad ; costa very gently arched ; 

 apex smoothly rounded ; hind margin also very smoothly 

 rounded but not very oblique ; dorsal margin nearly straight ; 

 basal portion of the wing pure white to near the middle and 

 throwing out a projecting angle into the next portion, which 

 is a broad central band of a leaden-brown ; on the median 

 nervure close to the base is a minute black dot, and beyond 

 it from the costa a faint brown cloudy dash ; no other traces 

 of the basal or first line ; second line, when visible, a deep 

 black series of small crescents and dots, which bounds the 

 central dark band, but is abruptly terminated by a large 

 quadrate white blotch upon the costa ; immediately outside 

 the second line is a faint series of whitish clouds, closely 

 followed by a second broad dark band, which is of a rather paler 

 leaden-brown, and is produced to the anal angle, but above 

 this is bounded by a rippled and curved white sub-terminal 

 line ; outside the lower half of this band the hind marginal 

 region is occupied by a large ovate white blotch in which is 

 a row of leaden-brown cloudy spots ; outside the upper 

 portion a more chocolate-brown blotch reaches the apex and 

 hind margin, and contains a partial row of white dots ; these 

 two portions of the margin extend their dark or white colour- 

 ing respectively to the cilia ; the reniform stigma is most 

 obscurely indicated by two whitish rings placed perpendicu- 

 larly. Hind wings shining pure white, with a broad, rather 

 sinuous, smoky-black band along the hind margin, but not 

 reaching the anal angle ; outside this band the extreme 

 margin and the cilia are pure white, the former a little dashed
