the early stages of Scolitantides orion. 427 



some pink shadings, half-way between this and spiracular line. 

 The curved eye is largely black, in two thin lines and threads 

 between them ; there soon appear also greenish patches on the 

 prothorax, head and wings, consisting of very small round spots, 

 either separate or aggregated ; these look as if they were to be 

 darker when the pupa is mature. The abdomen is thicker and 

 wider than the thorax, and the waist is definite, but not marked. 



The dark spots a few hours later appear all over the 

 pupa, and gradually darken as does the ground-colour of the 

 pupa ; the dorsal line becoming dark also, but less distinct. 



The photographs of portions of the pupa skin will show 

 its sculpture and armament better than much description. 

 The network is more netted and less dendritic than in 

 Plebeiids, thus more approaching Chrysophanids and 

 Thestorids, especially also in the presence of " rosettes " 

 at the junctions. The larval armaments are, however, 

 strictly of Lycaenid pattern.
