and the second and first discoidal nervules ; the next two black spots 

 with a yellow spot beneath each : in the discoidal cell is placed a 

 lengthened spot of kings-yellow. The anal angle kings-yellow, with- 

 out any black spot such as is found in the other species. The 

 base, nervures, and narrow margin deep black. 

 Length across the primary wings 6^- inches. 

 Mr. Westwood has remarked, that he was not sure whether the 

 present insect "might not be a local variety of Ornithoptera priamus. 

 I will, however, point out some dissimilarities, which induce me to 

 differ from so high an authority. The form of the primary wings 

 appears rather shorter and thereby broader than in O. priamus, while 

 the band that runs near the anterior margin is much broader ; the 

 middle and these wings are without the band that borders the poste- 

 rior and exterior margins, except at the base of the former, where 

 there is an abbreviated band, and but slight indication of spots 

 (formed by a series of minute specks) on the latter. The dull 

 black hirsute space is formed of a single large spot, which in 0. 

 priamus is composed of two, a large one and small one. 



The under surface of the primary wings has the golden-green spots 

 that occupy the spaces between the nervures divided by a wider 

 irregular band than is found in O. priamus. 



The secondary wings are without the black spots at the anal angle ; 

 and the marginal border is much narrower, while the edge is less 

 dentated than in O. priamus. 



The under surface of the secondary wings has various gold marks 

 not found in O. priamus : one in the discoidal cell ; and a spot above 

 each of the black spots between the second and third discoidal ner- 

 vules is very small, while the marginal black spots are further 

 removed from the outer margin : the discoidal cell is more broadly 

 surrounded with black. 



Many of these peculiarities cause Mr. Wallace's insect to approach 

 nearer the species I have named Papilio (Ornithoptera) rich- 

 mondia, than any of the others recorded in my Catalogue of the 

 family Papilionidce ; viz. the want of the posterior and exterior band, 

 the single form of the dull black space on the primary wings, the 

 increased number of the golden spots on the under surface of the 

 secondary wings, and the breadth of the black margin within the 

 discoidal cell. 



It may also be remarked that the female is decidedly more like 

 that of P. richmondia in its colour and markings than the same sex 

 of P. priamus.

The genus Sclerostoma, which forms only a section of the genus 

 Strongylus of Rudolphi, but which has been adopted by De Blain- 

 ville, Dujardin, and Diesing, is not numerous in species. Removing
