of a sii1)tiiangular foiin, the bases of the four outer being nearly confluent, and of the 

 three inner quite so, forming a straight line across the centre of the wing; the 

 attenuated ai)ex of each spot very nearly reaches the outer margin at each nervule. 

 On the lower wings the green band occupies the centre half, and has its upper margin 

 tinged with purple. The lower wings are finely white-edged. There are some azure 

 atoms near the base of the upper wings. The collar is crimson, and the thorax and 

 abdomen (?) black. Beneath black, upper wings with the green spots opposite the 

 bases of those above, small and notched, the basal one with brilliant purple reflexions, 

 also a purple streak on the anterior margin at the base. Lower wings with a sub- 

 marginal row of diamond-shaped whitish spots divided by the nervures ; base of wings 

 with two elongated patches of brilliant purple. Body obliquely banded with crimson ; 

 abdomen black. 



" Hab. N.W. Coast of Borneo. 



"This magnificent insect is a most interesting addition to the genus Ornithoptera. 

 The green-marked species have hitherto been found only in N. Australia, New Guinea 

 and the Moluccas, and all those yet known so much resemble each other in their 

 style of marking, that most of them have been considered as varieties of the original 

 Papilio Priamus of Linna)us. Our new species is therefore remarkable on two 

 accounts; first, as off'ering a quite new style of colouring in the genus to which it 

 belongs ; and, secondly, by extending the range of the green-marked Ornithopterae to 

 the N.W. extremity of Borneo. As it has not been met with by the Dutch naturalists, 

 who have explored much of the S. and S.W. of the island, it is probably confined to 

 the N.W. coast. My specimen (kindly given me by Captain Brooke Brooke) came 

 from the Rejaug river ; but I have myself once seen it on the wing near Sarawak. 

 I have named it after Sir J. Brooke, whose benevolent government of the country in 

 which it was discovered every true Englishman must admire.
