margins, more slender between, oblique and strongly 

 angulated ; second line black, similarly emphasized on the 

 two margins of the wing, in the middle portion broken up 

 into slender streaks, dots and angles, often edged by faint 

 smoky-black clouds ; central line black, angulated, oblique, 

 thickened upon the wing-margins and touching, or almost 

 embracing, a small black discal spot ; beyond the second line 

 is a series of smoky grey clouds broken by spaces often 

 whiter than the general colour ; hind margin edged with 

 minute black streaks ; cilia brownish-white clouded with 

 grey. Hind wings rounded behind, white dusted with grey- 

 black ; central spot black: just before it is a looped and 

 angled grey-black transverse line ; beyond it is a similar but 

 more slemler, undulated, and much indented line, followed 

 by a double series of smoky grey clouds ; extreme hind 

 margin dotted with black ; cilia brownish-white. Female 

 very similar. 



Under side of the fore wings very pale brown ou the costa 

 shading oft" to white at the dorsal margin ; on the costa are 

 two distinct black spots from which arise central and second 

 lines as on the upper side ; discal spot black, hind wings 

 a fainter reproduction of the upper side. Bodj^ and legs 

 whitish brown. 



Not very variable, except that a constantly recurring- 

 form or permanent variety, found sometimes at greater eleva- 

 tions ou the mountains, but obtained in numbers l)y breeding, 

 has almost the whole surface of the wiugs clouded with 

 smoky-grey, the markings darker, and the intermediate 

 blotches beyond the second line alone remaining white. 

 Aberrations are extreme!}* rare, but one in the cabinet of 

 Mr. S. J. Capper is unusually white exce]it toward the base, 

 wliicli is Ijlackened, the first line being .sutl'iised; the second 

 line in this specimen placed unusually wvm- to the hind 

 margin. 



On the wing in June and July, and in confinement a 

 second generation has been reared in September and October ;
