PAPILIO. 545 
111 the Loochoo Islands, where tliis species appears to be conimou, there 
is a large pale form of the female closely approaching agenor ; this form is 
figured by Pryer, who was apparently unacquainted with the true Japanese 
female. The males from the same locality agree with Cramer's figure of 
P. androgeos. 
In his paper on the Lepidoptera of Sikkim, Mr. Elwes (Trans. Ent. Soc. 
Lond. 1888, p. 428) states tliat " P. androgens is common in the lower 
valleys and found as high as 4000 or 5000 feet from April until December. 
The common form of female in Sikkim is tailed, with a considerable amount 
of white in and beyond the cell of the hind wing ; but tailless females are also 
found without any white markings, and others with a broad white patch on 
the hinder margin of the fore wing."

" Le dessus des ailes anterieures de ce Papillon Chinois est d'un lustre bleu obsour. Quelques 
petits grains bleus celestes sont disperses sur les posterieures, vers leur bord exterieur. II a 
six pieds ; selon la division systematicpe de Linnaeus on pent le ranger parmi les Chevaliers 
Troyens." {Cramer, I. c.) 
Outer margin of secondaries dentated, but not prolonged into a tail. 
Male. Primaries dark bluish grey, with the venation black, broad, velvety : black streaks between 
the nervules and in discoidal cell. Secondaries velvety bluish black, the costal and outer areas 
sometimes sprinkled with pale blue scales ; there is a black anal spot more or less completely 
encircled with reddish, the latter colour edged on the outer margin with white. Under 
surface : primaries whitish grey ; the basal area suifused with blackish ; venation and black 
streaks as above : secondaries velvety black ; there are some reddish lunules on the costal half 
of outer margin ; the black spot at anal angle is placed in a large irregular-shaped patch, which 
is dusted with pale lilac scales and is sometimes connected with a reddish ring near outer 
margin in the first median interspace. 
Female. Upper surface similar to that of the male, but tho primaries are sometimes brownish in 
colour; the reddish marks at anal angle and in first median interspace agree with those on 
under surface of the male ; on the under surface the reddish patches are large and diffuse, and 
there are five lunules on outer marginal area.
