appearing again in the spring and being full-fed in June. 

 The pupae may be found in that month and the next, 

 while the imago is on the wing in July and early 

 August. 



Adippe frequents woods and hill-sides in most parts 

 of England and Wales, but is local, though often plentiful 

 where it occurs at all. It does not, as some insects do, 

 become commoner as we proceed southwards, but, as with 

 the preceding butterfly, ag/aia, the spots where it is common 

 are scattered here and there through the country Lincoln- 

 shire, Westmoreland, and the New Forest being three 

 amongst others. It is not a Scotch insect. 



The larva (Fig. 80) is about the same size as that of 

 aglaia, and, like it, tapers towards the extremities. The 

 spines, too, are similar in number and disposition, but 

 in this case are yellowish-brown. The ground-colour is 

 a rich, dark pinkish-brown, the pink showing especially 

 on the lower surface. On the dorsal surface each segment 

 is adorned with two distinct comma-shaped (*) black 

 marks separated by a much lighter streak. The hairy head 

 is a dull lightish brown, and so are the legs and claspers. 



The pupa (Fig. 79), which is similar in shape to that 

 of the rest of the genus, has a very dark brownish tinge 

 with golden marks. 



The upper surface of the imago (Fig. 77) so closely 

 resembles that of aglaia in ground-colour, markings, 

 shape, and margins, that at first sight no difference can 

 be detected ; but a closer examination shows that the 

 dark blotch at the base of the hind-wings of aglaia is 

 replaced in adippe by less compact black markings, 

 though the base of the wings is often very dark too. 

 In the row of five black spots mentioned as occurring 

 on the hind-wings of aglaia, the one nearest the costal 

 margin and the middle one are small or wanting in
