 Third ,, ,, 8; ,, 16; ,, 19 mm. 



The abdominal fold of the 3 is rather complex, 

 beautifully formed, of a light pearly colour within, and 

 contains a large deposit of soft and short wooly material, 

 which, if drawn out with a needle would pile up to a 

 considerable height above the wing, as in the case of 

 some of the red and black species of S. and C. American 

 Papilios. In the 2 it is very simple, being very little 

 more than a convex structure, with the submedian nervure 

 running through the middle, and following very nearly the 

 curve of the inner margin. 



This species was found by Wallace in Amboyna, Ceram, 

 Gilolo, Morty Island, Sula Island, and Celebes. 



One $ example has been taken by Mr. Doherty in the 

 island of Sangir, and one 2 in Talaut ; but I could see 

 no special difference between them and the specimens 

 quoted above. Indeed this species does not appear to 

 me to vary much from the normal type in either sex. 



I have to thank Mr. Stanley Edwards, for the kind loan 

 of specimens from which the plate was drawn. 



In the museums of the author, Messrs. Godman and 

 Salvin, M. Oberthiir of Rennes, Hon. W. Rothschild, Mr. 

 Lambert, Exeter, and many others, in addition to the 

 collections named above.
