-1/((/c'. rriraarics deep velvety fuliginous shot with briUianfc blue, which colour appears in certain 
lights to bo the ground-colour ; a pale blue spot iu the discoidiil cell and one in each nervular 
interspace below it form an obhquo series of three, and from the middle one of these there is a 
curved series of five to the costa, beyond is a submarginal series of eight spots and a marginal 
series, but the latter does not quite reach the costa. Secondaries velvety brown, costal half, 
especially towards outer margin, ashy grey ; there is a whitish patch in the cell just below 
the origin of first subcostal nervule, and in some specimens a small blue spot just outside the 
cell between second and third median nervides. 
Female. Brown, darker towards apex of primaries. Primaries with a largo patch of bright blue 
on apical half; the spots are placed as in the male, but are white in colour; there is a whitish 
streak iu the ecU, and another between the median and submediau nervures. Secondaries 
have a marginal row of round white spots, a submarginal series of white streaks, which are 
short towards costa, but extend to the base of tho wing below median nervure, a discal series 
which increase iu length towards costa, and there ai'e four white streaks iu the discoidal cell. 
Expanse, d 75-120 miUim., $ 104-120 millim. 
As pointed out by Mr. Moore, P. midamus of Linuceus has long been con- 
founded Avith this species, which is probably due to the fact that Linnoeus 
himself refeiTed, "in his original description of P. midamus (Syst. Nat. 1758, 
p. 470), to Ehret's figure on plate iii. as well as to that on his plate xi., 
and in the Mus. UWcpe, p. 251, therein supplementing his description of 
P. midamus with that of the present insect." 
Common throughout Southern Asia. I have received the species from 
Ichang, Central China, and from various localities in "Western China, but it 
does not appear to have been common in any of the places. The Chinese 
examples agi'ee in almost evciy particular with specimens from Darjiliug. 
The larva of this species is refeiTed to by Marshall and de Niceville (Butt. 
Ind. i. p. 75) as follows : — 
" Ground-colour testaceous, marked with crimson and black perpendicular lines on the segments, a 
spiracular row of black spots and some yellow blotches just above the legs. The face is also
