224 DEL AGO A BAY. 



bluish-black aud white, but in many the white 

 is replaced by ochreous yellows of all shades, 

 sometimes only on the hind-wings, up to orange- 

 red this last being the rare P. Trophonius. 

 The light markings on the fore-wings also vary 

 much in form. 



In many other species the males and females 

 differ very much, but often the under sides of the 

 wings are exactly similar. In Godartia Wake- 

 fieldii the male is black with green markings, 

 whilst the female is black and white, and not 

 unlike a female Merope. The wings of the 

 Godartias are very much more rounded than 

 those of other butterflies, many being nearly 

 circular, aud this gives them a very singular 

 appearance when flying, the wings seeming to 

 revolve like paddle-wheels. The wings of the 

 female G. Wakefieldii are not so rounded as 

 those of the male, but still her flight is most 

 curious and unmistakeable. She is a most tan- 

 talising butterfly to pursue, flying only short dis- 

 tances and near the ground, but always settling 

 just where it is impossible to put the net.
