PIERID.E. 
Times of Appearance. — From April to August, being double- 
brooded. 
Habitat. — Common in the greater part of Europe, North 
Africa, Asia Minor, North and Central Asia as far as the 
Himalaj^as ; inhabiting open plains, fields, &c. It is one of the 
rarest of the British Butterflies, individuals of the second brood 
occasionally occurring on the south coast in August ; sometimes 
two or three captures are recorded in one season. PI. VII., 4. 
Larva. — Greyish blue, covered with small black granulations, 
with four longitudinal white stripes, and with a yellow spot on each 
segment. The legs and ventral surface are white. Chrysalis grey, 
speckled with black, and with reddish stripes. The larva feeds, 
like other species of the genus, on Cruciferce and Eesedaceie. 
VARIETY. 
Bellidice, 0. 1, 2, 154. Smaller than the type. The mar- 
ginal band of the fore wings less extensive, and powdered with 
white scales. Under side : — The fore wings without the inner- 
marginal spot in the male. Hind wings deeper green, not so much 
tinged with yellow ; the marginal spots are larger and narrower. 
This variety inhabits the same localities as the type, appea.nng in 
the spring. PI. VIII., 1.

llussius, Esp. 90, 1, p. 177. 
Expands 1'25 to 1’75 in. Wings white. Fore wings with the 
hind margin slightly concave ; the marginal band consists of 
blackish dashes, to the number of about five, running from the 
margin inwards : inside these there is, in the female, a black border 
running downwards from the costa. The spot at the extremity of 
the discoidal neiwiire is white in the centre. The female has the 
usual black spot near the inner margin ; it is, however, fainter than 
in the preceding species. The hind wings are white and unspotted 
in the male, but with small marginal lilack spots in tlie female. 
Under side: — Fore wings similar in their arrangement to those of 
Callidice and DapUdicc, but the green colour of the hind margin is
