COMMON BUTTERFLIES OF THE PLAINS OF INDIA. 523 



ridges converging towards each other in the lateral region but not meeting ; 

 the hinder ridge continued, narrower, as a white line forwards laterally 

 along segments 4, 3 to the front margin of segment 2, thus separating the 

 dorsal green portion of larval body from the watery greenish grey of the 

 ventral parts ; after this shield the body decreases gently in diameter to 

 the anal end, the dorsum transversely convex, the sides more or less 

 flattened and perpendicular to the flat ventrum or underparts. The 

 surface of the body is dull and velvety looking but is covered with 

 extremely minute erect hairs when looked at under the lens ; there is a small 

 dorsolateral, short, fleshy tubercle near hinder margin of segment 13, 

 coloured white-grey, on a similarly coloured, very slightly raised line 

 which separates the green dorsal colour of the body from the hinder slope, 

 and this line is continued forwards and down, still separating the dorsal 

 green from the lateral grey, to join the white subspiracular line at front 

 margin of segment 12. Spiracles not large, somewhat narrowly oval, light- 

 brown, bordered very finely black with a broader black line inside and 

 parallel to their margins. The colour of larva is a fine rich velvety, darkish 

 grass-green on the dorsal portions with a yellowish shade above the lateral 

 white line of segments 2-5 and above a pure white, subspiracular band 

 starting from the base of the anal claspers and running forwards to the 

 front margin of segment 7 whence, on segment 6, it curves upwards, get- 

 ting thinner, to lose itself in the supraspiracular region at the front of 

 that segment, leaving a triangle of ventral colour, between it and the 

 BwoUen hinder ridge of the shield of segments 4 and 5, intervening between 

 the dorsal green as far up as the subdorsal region ; indeed, when the larva 

 is stretched, the segmental membrane between segments 5 and 6 is visible 

 right round the larva and the hinder half of the membrane is jet black 

 dorsally and dorsolaterally ; the ridge along front margin of segment 4 is 

 ornamented with a fine, thin, black line running in deep open loops from 

 eye to eye and finally, bordered posteriorly with white, encircling the black 

 eye in a forward loop, the anterior part of which is anteriorly bordered 

 with yellow ; the eye itself is about 3mm. in diameter, has a dull blue, thin 

 line transversely across its middle and two contiguous, thinly black- 

 bordered, small, enamel-white spots above it towards dorsum of larva ; in 

 front of this line of loops and on front of ridge are two parallel, thin, black 

 lines, more or less interrupted throughout their length, with some six 

 thinly black-bordered circles let in between them ; the ridge along hinder 

 margin of segment 5 is, like this other ridge, lighter green thain the body- 

 colour generally, has no black lines but has the surface of the shield 

 portion of the segment running into its tumidity in little open loops 

 which do not reach its hinder margin and these loops are all coloured 

 violet, fading gradually forwards into the glaucuous green of the whole 

 shield ; the loops become white towards the extremities of this hinder'
