ILLUSTRATIONS OF TWO HITHERTO UNFIGURED SPECIES OF PAPILIO. 
—_9—— 
Papilio Rhetenor, Westw. n. sp. (Pl. 16, fig. 1 and 1a). Alis supra nigro-cyaneo nitidis, 
posticis oculo incompleto ad angulum ani albo supra rufo; subtus anticis griseis nigro 
striatis, basi sanguineis; posticis aterrimis margine omni anali late sanguineo nigro maculato 
angulo ani albo irrorato, Expans. alar. unc. 54. 
Turs fine species is a native of Assam, where it was collected by 
Mr. Griffith, and now forms part of Mr. Solly’s collection, alluded 
to in the last number of this work. On the upper side the wings 
are of a black colour, tinged with very dark blue, especially towards 
the outer angle of the hind wings, being there increased by a number 
of minute, slender, elongated, blue scales. At the anal angle is an 
incomplete eye, formed of a black spot, partially surrounded on the 
inside with a whitish crescent, the upper part of which is tinged 
with sanguineous. The fore wings beneath are of a grey colour, 
darker towards the base and along the outer edge, with the veins 
and intermediate longitudinal fascize black, the base being blood 
red; which colour extends broadly along the whole of the anal 
margin of the hind wings (except in the anal fold), marked with a 
black spot at the anal angle, which is much irrorated with white. 
The sanguineous colour in the next area of the wing is marked with 
three black spots, the middle one being the largest. The head and 
neck above are spotted with dirty white, and the antenne and legs 
are black. The abdomen is wanting in the unique specimen now 
before me. 
This species is most nearly allied to the Chinese P. Protenor, but 
differs in the anal eye, in the extent of the sanguineous colour 
along the whole anal margin of the hind wings, and in wanting the 
spots along the hind margin of the same wings. 
Papilio Agestor, Plate 16, fig. 2. (Gray in Zool. Misc. p. 32, Boisduy. Hist. Nat. Lep: 
1. p. 376.) “ Alis griseis venis margineque exteriore nigris griseo punctatis ; posticis 
corticinis disco punctato griseis.’’ Expans. alar. 34, 4 une. 
This curious species is described by Mr. G. R. Gray as a native 
of Sumatra, but the specimen now figured was obtained from India 
by W. W. Saunders, Esq., F.L.S., President of the Entomological
