ON NEW AND LITTLE-KNOWN LEPIDOPTERA, 171 
more especially as the shape of the tail with its broad base is 
very aberrant. On the upperside it is coloured and marked as in the 
same sex of A, alemon, mihi, Journ. Bomb. Nat. Hist. Soc., vol. vi, 
p- 371, n. 20, pl. F, figs. 20, male, 21, female (1891), which flies 
with it. 
Described from a single example taken by Major F. B. Longe, 
R.E., on 12th March, 1898. 
Family PAPILIONIDA. 
Subfamily Prerinz. 
17. METAPORIA PARACRAVA, n. sp. Plate EH, Fig. 19 é. 
Hapitat: se Kou, Western China (R. P. Dubernard). 
EXPANSE: ¢, 3°25 and 3°40 inches. 
Description: Matz. Upprrsipe, both wings differ from those of 
“ Pieris” acrea, Oberthiir, in having all the black markings of a 
very much deeper shade, dsep black imstead of dull black (judging 
from Oberthiir’s figure), and many of the broadly-bordered-with-black 
veins themselves defined with pure white; the veins in P. acrea 
appear to be entirely black. Forewing has the curved discal series of 
five white spots very much smaller and al] well isolated, in P. acrcea 
the three anterior ones would touch each other were they not divided 
by the black veins ; the marginal short white streaks between the 
veins much smaller and quite narrow instead of being almost quadrate. 
Hindwing has the five spots beyond the discoidal cell very much 
narrower; and the marginal spots are also smaller. Unpersipz, 
both wings as on the upperside, except that all the white markings are 
tinted with yellow, and that the hindwing on the outer margin 
has a pair of elongated whitish streaks in each nervular inter- 
space. Also near to Metaporia lotis, Leech, described from Wa-shan, 
Ta-chien-lu, Pu-tsu-fong and Moupin, all in Western China, in my 
collection from Pa Tse Fang and Tien-Tsuen, in Western China, 
received from M. Charles Oberthiir and named by him “ Pieris 
acreea,’ but differing therefrom in many salient characters as will 
at once be evident by comparing Mr. Leech’s figure of WM. lotis with 
mine of MM. paracrea, M. oberthuri, Leech, from Chang-yang in 
Central China, and Onei-shan in Western China, is another allied 
species, but is altogether a much whiter insect.
