304 LEPIDOPTERA. 



way between it and the hind margin ; the space beyond this 

 being clouded with dark brown. Between the first and 

 second lines is usually a broad ill-defined central brown cloud, 

 crossing the wing and partially obscuring a black dot in the 

 discal cell and a black crescent or V-mark at the extremity 

 of the cell. Cilia brown with regular, almost squared, black- 

 brown spots, which are sometimes very faint. Hind wings 

 rather long, much rounded, pale brown or umbreous, with 

 darker brown nervures, and sometimes a cloudy brown band 

 along the hind margin, most distinct upon the nervures ; cilia 

 pale brown, sometimes dappled with darker. 



Female extremely different (hence its name). Antennee 

 short, and shortly but distinctly pectinated, not curved down; 

 black. Head and thorax downy in appearance from abund- 

 ance of soft, raised, yellowish- white, or brownish- white 

 scales ; thorax robust ; abdomen very stout and heavy, 

 brownish-white shading to browner towards the anal segment, 

 which is broadly and bluntly tufted with dense yellow-brown 

 scales. Fore wings longer and rather narrower than in the 

 male, very ovate, margins all rounded, apex hardly angulated ; 

 white, faintly tinged with brownish, especially towards the 

 costa ; first and second transverse lines rippled and scalloped 

 throughout, the second deeply so ; between them is a cloudy 

 transverse central stripe which crosses a distinct black V- 

 shaped mark at the extremity of the discal cell ; between 

 this mark and the first line is a round brown spot in the cell, 

 and another lies at the base of the median nervure ; outside 

 the scalloped second transverse line is another, similar, much 

 less distinct, often partially obliterated ; and on the costa are 

 three brown spots or blotches, from which arise, respectively, 

 the two transverse lines and the central shade ; cilia whitish, 

 chequered with broad, squared, dark brown spots. Hind 

 wings shorter than in the male, semi-transparent whitish ; 

 nervures faintly brownish ; cilia whitish, with a row of dark 

 brown spots. 



Underside of the male — all the wings pale brown, rather
