COMMON BUTTERFLIES OF THE PLAINS OF INDIA. 761? 



of segment 2, 3 and 4 shiny black. Spiracles light brown surrounded by at- 

 black line. Shape same as 1st stage. L : 12mm. ; B: 4. 5mm, 



^rd Stage. — Similar to the 2nd stage in every respect as to shape and' 

 spines and colour. The L : 15 mm. ; B: 5-5mm. 



^tli Stage. — Similar to the 3rd stage in every respect except that the; 

 hairs covering the body are now mere indications showing as black pin- 

 points, being hardly raised. There is an indistinct, lateral, longitudinal, 

 white line from segment 4 to segment 13 ; a subspiracular line or narrow 

 band, yellow. L : 19mm ; B: 7mm. 



htJi Stage. (PI. C. fig. 16). — The shape is the same as in the 4th stage- 

 except that the dorsolateral tubercles of segment 4 are triangular, flattened 

 before and behind, shiny black at base and white on side, surrounded 

 at base by a black line, the two tubercles connected across the segment by 

 a distinct yellow ridge ; the dorsolateral tubercles of segments 2 and 3- 

 are similar in shape but considerably smaller : they are shiny and have a 

 few minute hairs on them. The anal points are as in 4th stage. The head 

 is green with a yellowish tinge with black eyes ; covered with fine hairs' 

 which are light in colour. The body is likewise covered with extremely 

 minute, light hairs. The colour is a fine rich green with segments 13 and 

 14, spiracular region, legs and prolegs greenish- white ; there is a fine 

 yellow lateral line and subspiracular yellow band from segment 6 to segment 

 13 ; the dorsolateral tubercles of segment 2 and 3 are white and black. L : 

 28mm.; B: 10 mm.; when stretched; L: 34mm. 



Pupa. (PI. 1, fig. 13a) — Is very like that of P. doson in shape, except 

 that here the thoracic process is at an angle of 45° to the longitudinal axis, 

 of pupa instead of 30°. Eyes prominent, with each a short point anteriorly, 

 these points separated from the very slight dorsal ridge of head by a small 

 sinus on each side of it ; a ridge runs from the point of thoracic process, 

 down it on each side laterally, and in a curved line to the dorsal margin 

 of wing along which it runs to about the middle of segment 8, being slight- 

 ly thickened about the centre of the wing-margin ; another ridge runs, 

 down the front of process and one posteriorly, the former continued down 

 the dorsal line of head, the latter down the dorsal line of segments 4, & 

 dividing into two diverging to become subdorsal, then lateral, gradually in 

 an even curve, these two being widest apart about middle of abdomen 

 whence they again converge to meet at base of cremaster ; there is also a 

 slight spiracular ridge from cremaster forward to thoracic process ; but 

 none of these carinations are pronounced; the shoulders are only 

 slightly prominent and have each a short, low ledge at an angle to the plane- 

 joining spiracular lines ; the cremaster is stout, square in transverse section^ 

 truncated at end and carinated down each of the four sides lengthways, 

 continuations of the body carinte. Surface minutely and shallowly rugose 

 Spiracles of segment 2 not any way peculiar ; others longly oval, small
