3o8 LEPIDOP TERA . 



apex is shaded with brown. Body whitish-brown ; legs very 

 long and slender, pale brown. 



Variable in the extent of the umbreous clouding, which 

 often extends from the costal blotch to the base, and occa- 

 sionally over the whole of the fore wings, which then are 

 unicolorous dull brown, or have only a whitish oblique dash 

 from the apex. Abroad it seems to become still darker, and 

 I have seen specimens from the Island of St. Helena nearly 

 unicolorous black-brown. 



On the wing from the end of June till August, and 

 probably in a partial second generation, in September and 

 October. 



Larva, when stretched out in walking, about half an inch 

 in length ; but its general attitude is to " hunch up " its 

 middle segments into a close loop, keeping the front and 

 hinder segments close to the surface on which it is resting ; 

 and for this purpose its figure seems specially adapted, the 

 head and three following segments being much smaller than 

 the fifth, sixth, seventh and eighth, all of which are tumid, 

 the hinder segments being also somewhat smaller ; there are 

 but two pairs of ventral legs, or twelve legs in all. The 

 colour of the back is dark purple or crimson-brown, very 

 glossy, making it hard to distinguish the obscure markings 

 upon it ; along the back runs a slightly paler central stripe ; 

 the subdorsal lines are faintly seen as paler brown lines edged 

 with blackish below ; the sides and undersurface are paler, 

 and more ochreous in tint ; taken altogether, the larva has a 

 general appearance of a dingy dark chocolate colour. 



When newly hatched it is quite translucent and glossy, in 

 colour rose-pink, rather paler towards the tail ; the head 

 blackish ; the skin furnished with some bristles. At the end 

 of a week the bristles have disappeared, and also much of its 

 translucent look, and the colour has become more like claret. 

 At the end of another week or ten days much of the purplish- 

 red has vanished, and the colour has become dark brown.
