red, terminal dots at the apices of the veins. Female, wpperside : ground- 

 colour varies as in the male, but sometimes it is chalky white at the bases 

 of the wings, with the terminal margins more or less broadly sulphur- 

 yellow. Fore wing : always with a round, sometimes quadrate, black, 

 discocsllular spot variable in size ; in some specimens the costa is black 

 only towards the apex of the wing, in others broadly black throughout and 

 opposite the apex of cell so widened out as to touch the discocellular spot. 

 In lightly marked specimens in addition to the discocellular spot 

 there is only an irregular, terminal, black band, dentate inwardly and 

 widest at the apex of the wing ; in others there is in addition a more or 

 less difluse, highly-curved, macular, postdiscal band that extends from 

 the costa obliquely outwards down to vein 7, where it often touches 

 the terminal, black band and thence is continued downwards and slightly 

 inclined inwards to interspace 1, getting gradually fainter and paler 

 posteriorly. Hind wing : a series of terminal, interspacial black spots 

 that vary in size and, in the dark form, coalesce into a terminal 

 black band. Underside : varies from white with a yellowish, sometimes 

 ochraceous, tinge to deep chrome-yellow ; markings as in the male 

 but still more variable ; in catilla the spot at the apex of the cell, in both 

 fore and hind wings, is enlarged into a large, reddish blotch, that on the 

 hind wing sometimes so much so as to occupy the apex of the cell, the 

 basal two-thirds of interspaces 4, 5, 6 and the middle third of interspace 7 ; 

 in some specimens it is continued posteriorly in a series of obscure lunviles 

 to interspace la. Antennae red, obscurely dotted with black ; palpi and 

 head above, red ; thorax clothed with long, yellow, sometimes greenish 

 hairs ; abdomen pale yellow ; beneath : palpi and thorax pale to dark 

 yellow ; abdomen white. Expanse : 46-87 mm. 



Larva. — Body cylindrical, of the same breadth from segment 5 to seg- 

 ment 12 ; anal end rather narrowed, roundly square at extremity. Head 

 round from front view and thick through ; the clypeus triangular ; the 

 surface of the whole head covered all over with fairly small, conical shiny- 

 black tubercles, each tubercle carrying a short hair ; colour green, slightly 

 yellower than the body ; clypeus also green, and tubercled ; antennse white, 

 jaws tipped brown-red. The head is slightly broader than segment 2. 

 Segments 3 and 4 slightly tumid along dorsoventral line. Surface of body 

 rather deeply, transversely parallel-lined, 7 lines to each segment (there are 

 always some one or two less in all these pierid larva3 on segments 2, 3, 4) 

 as usual ; the intervals between these lines have, each, a single row of 

 conical tubercles, each surmounted by a tiny hair — these tubercles numerous 

 and often touching each other or nearly so ; there are no tubercles on the 

 spiracular band or below it ; ventrum clothed somewhat sparsely with fine, 

 short, white hairs. Spiracles oval, slightly convex, white, situated in the 

 white-band. Colour is a rather dark, bright-green with a dark, dorsal, 

 pulsating line and a spiracular, broad, white line suffused with yellow on 

 segments 2-5 ; belly shiny light green ; the tubercles are green, frequently 

 dark metallic blue, increasing in size towards the spiracular region where 

 they often form a broad, supraspiracular band in some specimens ; in the 

 blue-tubercled individuals the head-tubercles are also blue. L :41mm.; 

 B : 5 mm. 



PujKi. — Is of the normal, smooth type with slight ventral wing-bulge and 

 papilionid suspension. Head triangular seen from above, produced into a 

 conical snotit which is continued smoothly and evenly into the outlines of 

 the head ; this snout as long as segment 2 and slightly turned up ; 

 segment 2 rather long, the dorsal line ascending at an angle of 30° to 

 longitudinal axis of pupa, convex transversely, the sides evenly continuous 

 with sides of head ; thorax with the dorsal anterior slope, slightly more
