'• 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 extremit)- 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 luuules ; at the angle is a 
small patch of blue scales. The body above is clothed with greenish hairs : on the underside 
the colours are much brighter and more varied. The base is occupied 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 gradu- 
ally 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 
colour extends also to the anal angle, and adjoining the tail are several luteous spots preceded 
by opaline- white lunules ; the space between them and the discoidal cell being rich dark 
brown. The whole underside has a glossy appearance. The body beneath is brown, the 
abdomen yellowish. The legs are red-brown. The specimen represented is a male. 
"The species is most nearly allied to P. peranthus.'' (Westwood, I. c.) 
Tar. hercilles, Blanchard = sciron, Leech. (Plate XXXII. fig. 1, d ■) " Ayaut le corps tres- 
robuste, I'aspect des especes du genre Charaxes, les ailes d'un brun fonce, travorsees par une 
bande d'un fauve pale et par une serie de taches marginales de meme nuance, les ailes 
posterieures pourvues d'un prolongement caudal de mediocre longueur, fauve avec une ligne 
mediane noire." {Blanchard, I. c.) 
Male. Velvety brownish black, base of primaries sprinkled with yellowish scales, markings of all 
the wings bright orange-yellow ; those on primaries comprise a broad central fascia, a blotch 
on costa at the extremity of cell, a central row of four spots, and a submarginal series of 
spots : the secondaries have a central fascia and submarginal row of spots, margins of anal 
angle tinged with chestnut, and above it is a short streak of bluish-grey scales. Under 
surface: basal third of all the wings rich chocolate-brown, central third yellowish white, 
and outer third fuscous with paler interrupted submarginal band ; there is a patch of 
chocolate-brown at the extremity of the discoidal cell on all the wings, and one at anal angle 
of secondaries. 
Female. Agrees with male, but the markings are rather paler.

The Chinese form of P. gyas, described as F. liercuJes by Blanchard, and 
as P. sciron by myself, differs principally from the type in having a broad 
fulvous fascia on all the A^-ings. 
It occurs in Western China at Chia-kou-ho in July, Huang-mu-chang in 
August, and at Omei-shan and Moupin.
