Mr. J. J. Walker on 
This is one of the commonest butterflies at Hong- 
Kong, and may be found everywhere in open places, 
flying over the blossoming rapeseed in December and 
January, and frequenting the mignonette in the " Happy 
Valley gardens ; I have found the larva and pupa on 
the latter plant. The winter specimens are much darker 
and more suff'used with black scales (especially beneath) 
than those taken from April onwards, and are the form 
described by Mr. Butler as Pieris sordida ; the summer 
broods being the P. claripennis of the same author. 
85. Pieris (Huphina) nerissa. 
Papilio nerissa, Fabr., Syst. Ent., p. 47 J, n. 123 
(1775). 
Pap. amasene, Cram., Pap. Exot., i., t. 44, fig. A. (1776). 
9 Pap. coronis, loc. cit., A. (1776). 
Not very common, but taken sporadically from 
December to May, and is very partial to the Lantana 
blossom. Unlike the preceding, the winter brood is the 
pale one, the summer specimens being very dark and 
richly marked. 
86. Pieris {Huphina) pallida. 
HupJiina pallida, Swinhoe, P.Z.S., 1885, p. 137. 
Scarce ; occasionally taken in the " Happy Yalley 
gardens from February to May. These Hong-Kong 
insects agree well with specimens of Huphina pallida. 
in the National Collection, recorded from Poena and 
Bombay. 
87. Pieris [Huphina) aspasia. 
Papilio aspasia, Stoll, Suppl. Cram., t. 33, figg. 3, 
3 C. (1790).

t. 9, fig. 21, a, h. 
The only evidence I have of the occurrence of this 
pretty insect in Hong-Kong, is a specimen in the 
Na.tional Collection labelled as coming from thence. I 
found it not uncommonly in the Philippine Islands, at 
Samboangan and Manila, in December, 1891.
