version of a usual Pierine pattern. It is, however, remarkable 

 that Mynes, a Nymphaline, should possess an upper surface 

 so strongly Pierine in aspect. A further point of interest is 

 the fact that Nepheroiiia jobaea, Boisd. S, the only member of 

 its genus to reach New Guinea, shows on its upperside a 

 likeness to Mynes doryca, which may extend even to the tint 

 of the pale ground-colour; while its underside, though without 

 red markings, is somewhat suggestive of a Delias. 



How far the principle of mimicry enters into these com- 

 binations may of course be questioned. That it has some 

 influence can hardly be doubted. More information as to the 

 bionomics of the forms referred to would be very welcome; 

 especially with regard to their distribution and habits.
