I'APILIOMD.K. 



For size and beauty of colour, this genus is unrivalled among the butterflies of the Old World, and few in the New 

 World can vie with it in either respect. 



There are two distinct types of colouring in the species, and each type has its distinct geographical range. 



The first group has the anterior wings of the males above of a rich velvety black, with splendid satiny blue or green 

 markings, the green varying with the light to an almost golden or coppery hue ; the posterior wings blue or green, 

 with orange and black markings. The females, as far as known, are brown, with dull white or yellowish markings. 



These species are peculiar to the more eastern of the Indian islands, as Amboyna, New Guinea, and the extreme 

 north of Australia. Orn. Poseidon was found in great numbers on Darnley Island by Messrs. Jukes and M'Gillivray, 

 flying very high amongst the groups of cocoa-nut trees. The natives of that little remote rocky islet capture them, 

 and, securing them by one end of a long thread, they fasten the other end of the thread to their hair, allowing the 

 butterflies to flutter around their heads. 



The second group have the anterior wings black, sometimes, especially in the females, marked between the nervules 

 with whitish streaks ; the posterior wings mostly of a golden yellow, with a black border of various width. These have a 

 range extending from the westernmost limit of the other group to Java, Sumatra, Ceylon, and the continent of India, 

 as far north as the Himalayas.
