Summer brood : 
vielete, Menetrius ; Amurland, Corea, and Jafian. 
mandarina. Leech ; >»ortliern China. 
ajaka, Moore ; North-west Himalayas (the spring form, which is smaller 
and less heavily marked with black, is unnamed). 
Distribution. Amurland, Askold, Corea, Japan, North and Central China, 
Sikkim, N.W. Himalayas. 
Pieris extensa. (Plates XXXVI. figs. 4 <? , 5 $ var.; XLIII. fig. G c? .) 
Vieris erutce, var. extensa, Poujade, Aun. Soc. Eut. France, 1888, p. xix. 
Pitris eurydice. Leech, Eutomologist, xxiv. Suppl. p. 5 (1891). 
" Envergure : J , 70 mill. ; $ , 76 mill. Cette variete ne difFure de I'espece precedente que par 
uiie taille plus grande et par les nervures a peine marquees de noir ou de brun, tant en dessus 
qu'en dessous, chcz la femelle ; la tache noire de I'apex du dessus des ailes superieures est 
aussi mollis etendue. Le bord costal des ailes superieures parait plus arrondi chez la femelle. 
" De'erit sur deux males et deux femelles. Moupin." (Poujade, 1. c.) 
Yar. eurydice, Leech. (Plate XXXYI. figs. 4 J , 5 $ .) Closely allied to P. mdete, ilenetries, 
with which species both sexes agree in general characters, but they are respectivelj- larger ; 
the clubs of the antennae are not tipped with yellow ; the discocellular nervules of primaries 
form a regular curve without indentation ; these nervules and the median nerve are thickly 
bordered with black scales ; there are two black spots in the second median interspace (confluent 
in the female) ; the black apical border of primaries is narrower than in melete, and extends 
along outer margin as far as third median nervule, and there is a small black spot at the end 
of second median nervule. On the under surface of primaries the discoidal cell is not 
sprinkled with black scales as it is in P. melete. The female is less suffused with black 
than the same sex of P. melete. 
Expanse, cJ 80-86 millim. ; $ , 72-76 millim. 
1 have accurate di-awings of the insects described by Poujade as Pieris 
erutce, Boisduval, and P erutce, var. extensa. The first-named is certainly 
identical with the Chinese spring form of P. melete ; whilst the so-called 
female of exttnsa is really a male of the summer brood, and agrees in every 
respect with the male type of my P. eurydice (Plate XXXVI. fig. 4 d ). 
The male type of extensa is almost identical with a specimen from Omei-shan 
(Plate XLIII. fig. 6) in my collection, which I consider to be an example 
of the first brood of eurydice. 
Occurs in July at Moupin, Omei-shan, Wa-shan, Chia-kou-ho, and Huang- 
mu-chang in Western China, and also at Chang-yang in Central China.
