LARENTID.-E— MELA NIPPE. 99 



hind margin is a broad sinol<y-ljro\vu cloudy band, tinged 

 with blue, and intersected by an irregular white line ; cilia 

 white, clouded and intersected with smoky-brown. Female 

 quite similar. 



Undersides of all the wings white, the markings of the 

 upper side reproduced, the stronger markings more faintly, 

 but the fainter emphasised ; all, however, cut off on the fore 

 wings by a white stripe along the dorsal area. Body and 

 legs whitish-grey. 



Usually constant in colour and niarlcings, though liable to 

 a slight fading to brown colour of the latter, even during 

 life. But in the collection of the late Mr. F. Bond, in Mr. 

 Webb's possession, is a very remarkable specimen, its central 

 band being obliterated except a very narrow stripe from the 

 costa to the middle of the wing, faced by an elongated spot 

 on the dorsal margin ; the place of the dark band is thus 

 mainly jiure white, but the soft grey of the marginal band 

 has extended inwards over much of the usual white band, 

 and its whole appearance is thus greatly altered. 



On the wing in June and the earh^ part of July ; but in 

 confinement casual specimens of a partial second generation 

 are sometimes reared in August. 



Larva cylindrical, very slightly attenuated in front; head 

 rounded, larger than the second segment ; very pale brown 

 or pale ochreous, dusted with dull black, and having a 

 distinct dark brown frontal V; colour of the body brow-nish- 

 ochreous, tinged with olive-brown at the incisions ; u^jon the 

 fifth to the ninth segments is a series of five spear-headed 

 white spots filled in with brown — often black-brown — and 

 placed at the apices of brown dorsal V-shaped marla'ngs. 

 which point towards, and are continued upon, the sides to the 

 spiracular line ; the first of these brown-centred white spots 

 is less conspicuous than the others. From the second to the 

 fifth segment, and from the ninth to the anal extremity is a 

 dark brown dorsal line and a broad whitish or pale ochreous
