94 LEPIDOPTERA. 



to the end of the discal cell, thence all black ; there is a black 

 dot on the base of the median nervure, and beyond it a trans- 

 verse row of about seven black spots ; parallel, and imme- 

 diately following, is the first line, curved, and rather scalloped, 

 interrupted at the nervures, black or dark grey ; a little 

 beyond it, and hcforc the middle of the wing, is the second line, 

 dark grey, double, similarly curved and almost parallel, broadly 

 interrupted at the nervures ; the space between the first and 

 second line is filled in with smoky-grey, and forms a trans- 

 verse band, divided by the nervures. Beyond the double 

 second line, and outside the discal cell, the whole broad space 

 to the hind margin is occupied by slender, dark grey, 

 excessively angulated lines, forming arrow-heads between all 

 the nervures, in series of three to each elongated space or 

 cell ; hind margin with a black spot between each pair of 

 nervures, from which, usually, a shorter or longer, black line 

 runs inward toward the inside of the next arrow-head mark, 

 so as in some cases to resemble a complete arrow. At the end 

 of the discal cell is a long, slender, bent, black lunule, and 

 on the costa near it several regular blackish blotches ; cilia 

 white, spotted with smoky-black. Hind wings rather small 

 and short, apex bluntly angulated, hind margin sinuous ; 

 clear white with the nervures brown ; a faintly indicated dark 

 grey central lunule ; cilia spotted with grey. 



Antennae of the female rather shorter and with shorter 

 pectinations ; abdomen very stout and clumsy ; fore wings 

 considerably broader, with the costal margin decidedly 

 rounded, colour greyer, markings more distinct ; hind wings 

 pale grey with a central lunule ; otherwise as in the male. 

 The front or costal margin of the hind wings is strongly 

 fringed with long outstanding white scales, and projects beyond 

 the costal margin of the fore wings when the insect is at rest. 



Underside of the wings of the male clear white, with the 

 nervures brownish ; a grey cloud exists along the subcostal 

 region of the fore wings. In the female the underside is 

 much clouded with grey, the lunule of the hind wings is
