ochre of the trigonal yellow marks of the underside ; the 

 lunations of the outer margin tawny yellow- white. 



The undersides of the primaries differ little from the upper; 

 the same may be said for the secondaries, except that between 

 the costal nervure and the first subcostal branch is a small 

 dark yellow irregular-shaped spot ; a small orbicular black 

 spot in the white between the submedian nervure and the 

 third median branch, and the white beneath all the black 

 orbicular spots contains a yellow acuminate mark filling most 

 of the space from the spot to the sinuate border, the lunations 

 of the exterior margin being also yellow ; neuration well 

 defined above the black. 



Head. — Eyes dark brown, margined with tawny white. 



Thorax. — Above tawny brown, with a narrow green- 

 ochreous longitudinal stripe ; beneath, lateral crimson-scarlet 

 spots occupying much of the space above and on each side of 

 the legs, the remainder tawny brown. 



Abdomen. — Above greenish-ochreous white ; subdorsal 

 brownish ochreous-yellow, with strong black articulations and 

 five lateral black dots. 



Length of costa 102 millim. ; antennai and abdomen each 

 37 millim. ; head and thorax 25 millim. 



From the foregoing it would appear that the pattern is of 

 the same type and well within the limits of the variations in 

 the species aruana \ and this insect might well be taken as a 

 female var. of that species. In the case of the male it would 

 be impossible to make a mistake. 



Hah. Aru Islands. 



This species will be fully figured in the fifth part of the 

 author's ' Icones Ornithopterorum.'
