Heterocera from China, Japan, and Corea, 263 
mandschurica ; these examples he says are not larger than 
a medium-sized selene. Other specimens received at the 
same time exceed artemis in size but are much smaller 
than sedene and have the same shaped tails and the pointed 
wings of the latter, and therefore differ in these characters 
from artemis, Mandschurica is further described as 
follows—the primaries have double dark transverse lines, 
of which the outer is generally rudimentary ; the second- 
aries have a dark, sometimes faint, transverse line which 
turns off sharply to the abdominal margin ; ocelli as in 
artemis but rather larger. 
Staudinger adds that se/ene has also large ocelli which 
are tinged with pink on the outer half, but this species 
may be distinguished from his mandschuwrica by the tails, 
which in the males are broadly coloured with pink on the 
upper portion and more slightly so in the females. 
Ningpoana, Feld., is described as having the outer lines 
hardly conspicuous, smaller ocelli and being entirely without 
lilacine markings on the anal portions of the secondaries. 
Gnoma, Butl., has narrower and more divergent tails than 
artemis, and dulcinea, Butl., appears to be a slight modi- 
fication of gnoma. 
I find that the species varies in expanse from 108 to 153 
millim. in the male and from 116 to 168 millim. in the 
female. In colour the variation is from pale bluish-green 
to yellow faintly tinged with green. None of the transverse 
markings is constant; in some specimens one or other of 
the lines may be strongly defined, whilst in other examples 
all the lines may be entirely absent: the ocelli vary in size 
and shape, and the tails may be as short and obtuse as in 
A, isabellx from Europe or as long as in extremes of the 
typical form of A, selene. The pink coloration on the upper 
portion of the tails and the outer parts of the ocelli is 
sometimes present and sometimes absent in either sex, and 
in Indian as weil as in Eastern Asian specimens. 
All these variations together with their intergrades, and 
with other aberrations in addition, are represented in the 
series of twenty-five examples which I have retained out 
of a large number of specimens received from Amurland, 
Corea,:and various parts of China and Japan. 
It is of the greatest importance when dealing with a 
variable species, such as A. selene, to have an extensive 
series in which all the named forms are represented as 
well as the connecting links. Had Dr. Staudinger pos-
