and shining. The ground-colour of the caterpillar is a 

 dark violet-grey, paler at the divisions between the seg- 

 ments. There is a slender black dorsal line, bordered on 

 each side with dull yellow, and the lateral surfaces are 

 thickly marked with black. The spiracles are black and 

 grey-edged. Below each is a yellowish-red blotch, followed 

 by a thin yellowish line, while the ventral surface is dark 

 brown. 



The chrysalis (Fig. 76), which is suspended from the 

 under-surface of a leaf, has, like paphia, the abdominal 

 part very much curved, the segments of it being well 

 defined and bearing on the dorsal surface two rows of 

 points, calling to mind to some extent the rows of spines 

 on the larva. The anterior part is black, marked a little 

 with yellowish-brown, while the rest of the body is brown 

 and brownish-yellow. The thorax is humped above and 

 the wing-cases are prominent below; the spiracles are black, 

 and the whole surface of the chrysalis has a shiny, polished 

 appearance. 



On the upper surface (Fig. 73) of the imago the ground- 

 colour is a rich sienna-brown. The nervures are black, 

 and towards the base of the fore-wings are joined by 

 several irregular black bars. Nearer the hind-margin, 

 which is nearly straight (concave in paphid), is a row of 

 seven black spots, the middle one being smaller than the 

 rest. Outside these again is a row of semi-lunar black 

 markings, followed by two thin black lines swelling out 

 at the nervures. At the base of the hind-wings is a large, 

 irregular dark patch (not so much developed in adippe), 

 which patch is followed towards the hind-margin by a 

 row of five spots, the central one being the smallest ; the 

 rest of the markings resemble those of the fore-wings. 

 The fringe is pale, but black at the nervures ; all the wings 

 are slightly scalloped. On the under-surface (Fig. 74) the
