THE COMMON BUTTERFLIES OF THE PLAINS OF INDIA. 94 



the rest of the wing by a straight, white boundary often composed of two 

 separated luniiles, the outer opposite the 18mm. long tail at the end 

 of vein 2, the inner opposite the space between the long tail and the inner 

 tail; the black extremity' also bordered below by white from tlie anal angle as 

 far as the base of the long tail; a short white line inside this latter white mark 

 at the extreme margin indicating the interior attachment of a small, brvish-like 

 appendage. Underside : both wings pure white with a slight lustre, the apex 

 somewhat broadly and outer margin tinged with brown ; a delicate, brown line 

 on the discocellular veins ; a complete postmedial line composed of interrup- 

 ted, short lines between the veins ;the two in interspaces 4, 5 moved out- 

 wards ; a very obsolete submarginal, similar line. Hind wing : with a post- 

 medial similar line to that on the fore wing but inside it and not continuous 

 with it, composed of similar lunules from the costa to vein 4, then of much 

 more arcuate marks curving round to the middle of the anal margin ; a simi- 

 lar submarginal series from costa to anal margin parallel to the postmedial 

 line ; outside this again a series of four deep-black spots, marginal, from the 

 interspace 3 to anal lobe inclusive ; the uppermost and last but one gener- 

 ally much smaller than the other two. Cilia of fore wing brown, of hind wing 

 white.— Female. Exactly like the male except that the white, transverse bands 

 above the tails on the upperside of the hind wing are far broader and there 

 is no purplish gloss. Antenna3 black with a few white scale below ; head, 

 palpi, thorax and abdomen brov/n above, white beneath ; the eyes bordered 

 with white and vertex of head with a white central line. Expanse : male 

 and female, 40mm. 



Very rarely specimens are found with a white, discal patch on the fore 

 wing in the Kanara District. About half a dozen insects of the same brood 

 were bred bearing this patch. 



Egg. — Nearly hemispherical in shape, broadest just above the base ; the 

 surface covered with seven rows of coarse-walled cells, irregular in contour, 

 from summit to base; shining. The colour is enamel-white. L : 1. Smm ; 

 B : 1mm. 



Larva. ( PI. II, fig. 25). — The shajye is that of the larva of BatMnda but 

 it diflers in having a dorsal ecries of short, rather hooked, fleshy teeth on 

 segments .5 — 10 instead of the tentacular processes described for that genus 



The head is shining light-yellow in colour, rather small, round and is hid- 

 den under segment 2. Segment 2 rounded along the free margin, some- 

 what narrowly indented in the dorsal line of front margin and, again, laterally 

 with a small, rounded sinus, the margin somewhat thickened ; anal segment 

 square behind at the extremity ; segments 11, 12 broadened out at their 

 common margin into a sort of triangular, rounded tooth on each side so 

 that the body is little narrower across there than it is at the broadest part, 

 segment 5 ; segment 11 has the gland situated on a transversely sv.ollen 

 fold near the hinder margin. The body is considerably broadened out a 

 segment 5 gradually increasing in width and evenly, from the front, then 

 narrowing again as evenly though more gradually to segment 10, increasing 

 much more rapidly to the tooth at the common margin of segments 

 11/12, thence narrowing to the extremity ; the dorsal outline is more 

 or less straight from the anterior end at head up to the top of segment -5, 

 sloping at about 45° when the larva is at rest with the head tucked in and 

 the front segments somewhat contracted, then convex over the top of seg- 

 ment 5, after which, with a slight concave curve it runs down to segments 

 11/12, thence sloping nuich more rapidly for the short distance to the end ; 

 the ventrum is quite flat and closely applied to the surface ; the dorsal out- 

 line, further, toothed on segments 5 to 10 by one single, 1mm. long ( barelj^ 

 that), hooked, laterally compressed, sharp, broad-based, fleshy tooth in the 

 middle: the first four directed somewhat slantingly backwards, that on seg-
