268 LEPIDOPTERA. 



transverse stripe, outside which the margin is faintly clouded 

 with brown ; cilia very long-, pure white. Fore wings of the 

 female very slightly narrower, the ground colour a little 

 darker ; hind wings clouded with brown from the base and 

 becoming uniformly pale smoky-brown beyond the transverse 

 stripe to just before the hind margin, where there is a narrow 

 white space edged with dark brown marginal crescents ; 

 antennas threadlike ; abdomen stout ; otherwise similar. 



Underside of the fore wings pale smoky-brown except at 

 the hind margin, which is broadly — and the costa toward the 

 apex, which is narrowly — brownish white ; hind wings white ; 

 central spot and the following transverse stripe conspicuously 

 smoky-brown ; hind marginal space and cilia white ; but in 

 the female clouded with smoky-brown. Body dusky white ; 

 leg tufts dark smoky-brown ; legs dark brown, barred with 

 yellow. 



Rather variable in the tone and depth of the ground 

 colour, which in some individuals is tinged with chocolate- 

 brown, in others with grey-brown or slate-grey ; also in the 

 colour of the pale markings, which often are of a brownish- 

 white, or, on the other hand, are broadened and rendered 

 more conspicuous. More rarely the markings are partially 

 obliterated, the basal portion and that between the second 

 and subterminal lines becoming almost wholly dark brown. 

 These variations are rather of a local character, though every 

 intermediate shade is found, specimens from the Isle of 

 Portland being often of a dark grey colour, while those 

 from Devon have the white markings tinged with brown. 

 Occasional specimens are found of a pale olive-grey with 

 very faint markings; but one such, in the collection of 

 Mr. R. Adkin, has the row of black-brown wedges before 

 the subterminal line very large, conspicuous, and complete. 

 In all these cases the colour of the insect as preserved in 

 the cabinet is referred to. From a statement by Mr. N. M. 

 Richardson, it appears that — at any rate, at Portland — living 

 or freshly killed specimens have a distinct tinge of violet or
