PIERIN^. 
small yellow spots in hind-marginal border, close to apex ; terminal 
disco-cellular black spot rounder and usually larger than in ^ ; a 
black projection from costal edging (as on under side of — very 
rarely extending almost to disco-cellular spot. Hind-iuing : costal spot 
near apex united to hind-marginal border, which inwardly radiates more 
or less on nervules, and contains a single yellowish spot close to apex ; 
disco-cellular terminal line rarely distinct. Under side. — Varying 
from Umon-ydloio to deep cliroine-yellow ; hind-wing often inclining to 
%vhitish. Forc-iving : some tint of yellow between the two just men- 
tioned, suffused from the base with orange or orange-yellow ; spots in 
hind-marginal border yellow, usually seven. Hind-iving : neuration 
more strongly and generally black-clouded ; six or seven spots in hind- 
marginal border. 
Variety A. (P. Boguensis, Felder), $ and ^. — Fure-iving : in both 
sexes, instead of merely a small terminal disco-cellular spot, a well- 
marked (sometimes rather broad), short, oblique, blackish bar from 
costa, where it is wider and somewhat diffused. 
Larva. — Dull reddish-sandy on back, with a median longitudinal 
streak of violaceous-grey. On each side succeeds a wide ferruginous- 
brown stripe, followed by a narrow pale-yellow one, fringed inferiorly 
by thinly-set white hairs of moderate length. All the dorsal surface 
except the median streak shagreened with minute elevated whitish or 
yellowish dots arranged in transverse lines ; also across the back of 
each segment (rather before its middle) a series of much larger widely- 
separated elevated and acuminate yellow dots, — six on the second, third, 
and fourth segments, and four on each of the others, — followed (a 
little beyond middle of each segment) by two similar dots. Ventral 
surface, including legs, pro-legs, and under part of head, pale greyish- 
green. Head above ferruginous, in front inferiorly yellowish ; sha- 
greened like dorsal surface, and with two or three larger acuminate 
spots on each side ; inferiorly and laterally with some thinly-set white 
hairs like those on body. Length, 9 lin. 
In its earlier stages, down to a length of only lin., the larva is 
dorsally much tinged with greenish. 
Pupa. — Pale-brownish with a reddish tinge, or pale-creamy with a 
greenish tinge, superiorly more or less speckled with blackish. Cephalic 
process, dorsal ridge of thorax, and acute projections on each side of 
back of second abdominal segment, outlined with black. Blackish 
irroration in brownish specimens extending quite across back of each 
segment, only leaving clear a narrow incision-bar ; but in creamy 
examples restricted so as to form four longitudinal series of small 
spots. Mixed with this irroration on each segment are three or four 
transverse series of minute whitish spots, and also towards the front 
of each segment a transverse row of larger elevated yellow spots (four 
on each abdominal segment, six or more on each thoracic one). 
Beneath creamy -white or greenish - white ; wing -covers streaked
