362 Gervase F. Mathew's life-ldstory of three 



in the same manner as those of Papilio Schmeltzi, and 

 were similar in every particular. They were also 

 terribly attacked by the same kind of parasite. Here, 

 however, the similarity ceases, for the larvae, chrysalids, 

 and perfect insects are quite different. 



The young larva is black, with a white V-shaped 

 mark on the back, running through the 5th and 6th 

 segments. Spines black, those upon the anterior seg- 

 ments being the longest, and curved backwards at their 

 tips ; head black and shining. 



After the first moult there is very little change, the 

 white V-shaped mark is slightly larger, and the general 

 colour .smoky black. 



At the third stage the head is black and shining ; 

 general colour dusky black ; a greyish-white oblique 

 stripe runs up from spiracular line from 5th segment to 

 apex of 6th segment, and joins over the back, and 

 appears, when the larva is viewed from above, like a 

 broad V-shaped mark ; a shining white line just above 

 each of the ventral claspers ; subdorsal conspicuous, 

 curved pointed spines upon 2nd to 13th segments, those 

 on the 2nd segment the longest, and pointing outwards, 

 and slightly curved backwards at the tip, and with an 

 additional small spine at their base ; and there is also 

 an additional spine upon the 3rd and 4th segments, 

 between the subdorsal row and spiracles ; the spines on 

 6th to 8th segments are very small ; ventral and anal 

 claspers slaty gray. 



The fourth stage is similar to the third stage, with 

 the following exceptions : the whole larva has become 

 very shining, and looks as if its skin was too tight for 

 it ; the V-shaped mark is much smaller ; the spines 

 are smaller, and of a golden-brown colour, tipped with 

 black ; the spines on 6th to 8th segments have dis- 

 appeared ; the white stripe above the ventral claspers to 

 anal segment is much broader ; the ventral claspers 

 shining whitish grey. 



The full-grown larva is from 50 mm. to 55 mm. long, 

 rather plump, tapering slightly towards the anal 

 extremity, and with the 4th, 5tli, and 6th segments 

 considerably thickened ; whole colour a beautiful golden 

 green ; obhque darker green stripes pointing backwards ; 

 a darker narrow dorsal line widening out to a diamond- 

 shaped longitudinal spot at the segmental divisions ; a 

 double stripe between this and the oblique stripes ; from
