PLATE XI. 
DESCRIPTIONS OF TWO NEW SPECIES OF PAPILIO FROM 
NORTHERN INDIA. 
In the fine collection of Assamese insects, collected by Mr. 
Griffith, already alluded to in p. 17, and which has supplied mate¬ 
rials for two very interesting memoirs published by the Rev. F. W. 
Hope, in the Transactions of the Linnsean Society, are several 
new species of Papilio, amongst which that represented in the two 
lower figures in plate 2 is especially worthy of notice on account 
of the very peculiar character of the markings of the under surface 
of the wings. It may thus be characterized :— 
PAPILIO GYAS, TV. Plate 11, fig. 1 & 1. 
P. alis anticis subhamatis posticis caudatis; supra fuscis margine obscuriori luteo submaculatis, 
macula parva caerulea ad angulum ani; subtus brunneis medio pallidis lunulisque sub- 
argenteis notatis.

The wings above are of a dull brown colour, the anterior having 
a dark brown triangular spot about the middle, extending across 
the discoidal cell, at the extremity of which is a second similar 
spot; the outer margin is darker, with six luteous submarginal 
patches; between the apex of the wing and the extremity of the 
discoidal cell are three indistinct oval patches of a similar colour. 
The hind wings are similarly coloured, but the margin is darker 
brown and wider, and the luteous spots assume the appearance of 
indistinct lunules; at the anal angle is a small patch of blue scales. 
The body above is clothed with greenish hairs ; on the under side 
the colours are much brighter and more varied. The base is occu¬ 
pied by a large space of rich dark red-brown, or maroon, of which 
there is also a patch at the extremity of the discoidal cell. This 
is succeeded by a bar of whitish fleshy-coloured tint which passes 
gradually to brown and purple; near the apex of the fore wings is a 
large patch of pale opaline colour, from Which extends a bar of 
fulvous brown, terminating above in white angles preceded by 
purplish and obscure brown arches, the margin is brown, within 
which is an obscure bar of luteous. The extremity of the discoidal 
cell in the hind wings is occupied by a dark brown patch preceded 
by a white opaline arch edged with black; a bar of the former
