188 NTMPHALID.E. 
All the wings have the hind margin tinged with green, and with a row of orange lunulas, 
complete on the hind wings, -but on the fore wings interrupted towards the anal angle. 
Underside orange, with the spots and stripes greenish ; hind wings with a row of blackish 
spots parallel to the hind margin, and with the inner margin greenish gre}'." {Lang, I. e.) 
" Larva. Green, mixed with reddish brown and yellowish white, with two rows of fleshy elevations 
covered with bristles. Fiipa. Dirty white ; thorax with a dark brown dorsal patch ; wing- 
cases dark brown. The larva feeds on Pojndus aJha and P. tremula in May. It appears first 
in the autumn, and then hybernates between dead leaves." {Lang, I. c.) 
Var. tremulae, Esper. A form of the male in which all the white markings are absent, excepting 
those towards apex, and sometimes even these are obscured. 
Referring to the occurrence of Z. ])opuU in Japan, Pryer [I. c.) says that the 
species has only been observed in the Island of Yesso, and that his collector 
obtained several specimens there in the year 1882. These specimens are now 
in my possession, and I do not find that they differ in any way from European 
examples of the type-form. 
In Western China the species appears to be fairly common. I have received 
specimens from Ta-chien-lu, Wa-shan, Wa-ssu-kow, Pu-tsu-fong, and Ni-tou. 
All the males are either of the tremulxe form, or intergrades between that 
form and the type. The female, of which sex I have only one Chinese 
example, agrees with European specimens of this sex, but the white band on 
secondaries is rather narrower. 
This species appears to be widely distributed in xVmurland, Avhere the var. 
ussuriensis, Staudinger, which has the white bands in the male as broad as 
those in the female from Europe, is the dominant form. Dr. Staudinger (Rom. 
sur Lep. iii. p. 144) mentions a very small form of the male from Raddefka, 
for which he proposes the name of lilijjutana.

"Male. Upperside dark olive-brown from base to disc of fore wing, and from base to one third of 
hind wing, the rest being pale olive-brown ; a transverse dark band crossing the disc of fore 
wing and middle of hind wing ; a dark submarginal wavy line and two indistinct inner wavy 
lines crossing both wings ; some indistinct markings within the discoidal cell with paler 
centres, and a small green patch at anal angle. Underside of a golden-glossed obscure ash}-- 
brown ochreous colour. Fore wing with markings at the base, a transverse row of lunulated 
marks, and an indistinct submarginal row of very small spots, purple-ashy ; also a whitish 
patch at the apex, and a narrow yellowish line across the disc. Hind wing with broad inner
