PIKRIN^v 69 



small yellow spots in liind-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-wing : costal spot 

 near apex united to liind-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 lemon-yellow to deep clirome-yelloio ; hind-wing often inclining to 

 whitish. Fore-wing : some tiut 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 $. — Furc-u-ing : 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 Avith 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 leng-th of only 4-|^ 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
