COMMON BUTTERFLIES OF THE PLAINS OF INDIA. 749 



transverse bands from costa to tornal angle ; the two bands coalesce below 

 vein 4 and terminate in a point at the tornus ; the white portions of the 

 cell anteriorly overlaid with pale green ; short, macular, hyaline green 

 bands between the black, cellular, apical band and the discal band and 

 anteriorly between the latter and the terminal band. Hindwing : basal 

 three-fourths uniform white with black markings on the underside that 

 show through by transparency ; terminal fourth dark grey traversed by a 

 curved, irregular, subterminal series of black lunules that ends in a black 

 tornal spot and a terminal, black band that follows the indentations of the 

 wing ; the emarginations below the black, terminal spot edged with ochra- 

 ceous ; the tail blackish grey, edged and tipped with white. Underside : 

 forewing similar with similar markings, but the green shading over the 

 white portions in the base of the cell more decided ; the discal and termi- 

 nal, black bands separate, not joined posteriorly, the former edged poste- 

 riorly on both sides with dark grey, due to the black on the upperside 

 that shows through by transparency. Hindwing : basal half green, the 

 outer half white ; a large black, tornal spot ; a black line along the dorsum 

 that curves above the tornal spot outwards to vein i^ ; a straight, subbasal 

 black band from costa across cell that terminates at vein 2, joining the 

 dorsal black band ; a broader, black band from costa across apex of cell 

 extended into base of interspace 3 ; an irregular, discal series of black 

 markings curved inwards posteriorly towards the tornal spot ; a subter- 

 minal series of very small, slender, black lunules in pairs (variable in size 

 and distinctness), the ground-colour on the inner side of these darkened 

 to rich ochreous yellow ; lastly, a series of short, terminal, black bars in 

 the interspaces so arranged as to follow the indentations of the termen ; 

 tail dusky black, edged with white. Antennae black ; head and thorax 

 iinteriorly wdth broad, black, median band, rest of thorax bluish ; abdomen 

 white marked beneath on each side by a black stripe. — Expanse 90-104mm. 

 Larva. — The caterpillar of this species is very like that of P. nomius in 

 general facies, especially when young. The head is rather round in shape, 

 drawn under segment 3 in repose ; it is green in colour. Segment 2 is 

 little broader than the head and is slightly convex, trapezoidal in contour, 

 with a thin ledge along the front margin. Segments 2, 3 and 4 taken to- 

 gether are trvmcated — triangular in shape,very slightly convex transversely, 

 the base of the triangle being the hinder margin of segment 4, the truncated 

 apex being the front margin of segment 2 ; the lateral sides of these seg- 

 ments are nearly perpendicular to the ventral surface, even slightly sloping 

 in towards the legs. The hinder margin of segment 4 is the broadest and 

 highest part of the larva, whence the body gradually decreases in diameter 

 to the cremaster which is somewhat long and narrow, running out at each 

 corner of the truncated end into parallel, rather long, sharp points, one to 

 each corner, separated by a straight line between their bases. The dorsal
