J. Wood-Mason — Description of a netv Papilio [No. 3, 



the underside showing through. Anterior iviiig with the apex angulated 

 but not produced, the outer margin arched instead o£ concave-sinuous, and 

 the inner angle not so broadly rounded. Posterior wing darker-coloured 

 and also paling towards the outer margin, but with the submarginal series 

 of arcuate marks smaller and less distinct. Underside coloured and 

 marked in much the same manner, but with more perfectly formed and more 

 numerous ocelli ; the anterior wing having three (the first between the 

 submedian vein and the first median veinlet, the second the largest and best 

 defined) perfect ocelli and two or three rudimentary ones following them, 

 and the posterior wing, one rudimentary (close to the submedian vein) and six 

 (the first in the same interspace with the rudimentary one, and the second 

 the largest of all) perfect ones ; each ocellus dark brown encircled by 

 a very fine line of the colour of the strigte and pupilled with iridescent 

 silvery-white ; the thin submarginal brown line rather more deeply 

 engrailed. 



Length of anterior wing 1-3.5 ; whence expanse = 2-8 inches. 

 Hab. Sibsagar, Assam (S. E. Peal). Two specimens.

$ . Wings above cretaceous- white, the anterior ones black at the 

 insertion, scarcely tinged with greenish at the base, with five black bands 

 commencing at the anterior margin and cutting the cell, the first basal, 

 extending to the inner margin, the second rather broader, also extending 

 to the inner margin, and emitting a short conical process at the origin of 

 the first median veinlet, the third scarcely broader, extending to the median 

 vein, tlie fourth narrower, triangular, reaching or all but reaching the 

 median vein, the fifth much the broadest of all, triangular, divided anterior- 

 ly into two forks by a curved narrow decreasing and interrupted band of 

 the ground-colour running from the costal vein to the third median veinlet, 

 extending to the inner margin, separated from the black outer marginal 

 band by a band of the ground-colour divided by the black veins and very 

 sliglitly if at all narrowing from the anterior margin up to the second median 

 veinlet, whence it gradually decreases in width and distinctness to the inner
