PAPILIO.

colour and ornamentation similar to these characters on the upperside, but somewhat 



fainter. Head, thorax, and legs black. Body bluish black. 

 Female. The primaries are rather darker, there are a few bluish scales below the centre of the 



secondaries, the tails are slightly more rounded, and the red marginal markings of the under 



surface of secondaries are more pronounced. 

 Expanse loG millim. 



This species can at once be separated from any other known Papilio by its 

 broad spatulate tails, which are traversed to their margins by two (the 2nd 

 and 3rd median) nervules. 



The original specimens were from Kiukiang. I have since received 

 examples from Chang-yang in which the discoidal cell of secondaries is filled 

 in Avith white intersected by black vein-like streaks, the white extending beyond 

 the cell in the form of a triangular spot. 



I am indebted to Mr. John Watson of Manchester for the loan of a 

 drawing of a female specimen from Central China. Mr. Grose Smith has 

 also kindly lent me for examination two examples of this sex of P. elwesi 

 which he received fr'om Ichang.

Male. Fuliginous black, generally marked with red at the base of the primaries ; neuration of all 

 the wings, streaks between the veins and in discoidal cell of primaries, black. The second- 

 aries have the outer margin deeply excavated between the nervules, the tail is short and 

 spatulate; there is generally a large white central patch divided by the third median 

 ncrvule, sometimes a smaller one below in the first median interspace and a still smaller one 

 in the submedian interspace ; the red markings comprise a spot at anal angle surmounted by 

 a lunule, a lunule in first median interspace and four lunules on outer margin. Under 

 surface paler than above; all the wings are marked with red at the base, the white central 

 spot rather larger, all the red lunules on outer margin are surmounted by others, and that in 

 the submedian interspace is sometimes united with the lunule in the next interspace by a red 

 streak along the first median ncrvule. Head and collar marked with red. Abdomen black 

 above, red beneath. 



Female. Subdiaphanous, fuliginous grey, markings as in the male. 



Expanse, J 116-123 millim., 5 121-126 millim. 



The white spots on the central area of secondaries vary considerably in size
