8 PAPILIO MAOHAON. 



face and two black streaks down either side, the ocelli in 

 a black patch below, the mouth marked with black in 

 the centre and on each side, papillse whitish. On the 

 front marginal ridge of the second segment occur two 

 orange spots and two black spots in front of them close 

 to the head, and between these pairs of spots is the 

 concealed orifice whence the retractile soft fleshy horns, 

 of pinkish-red colour, dart forth when the larva is irri- 

 tated ; and when seen at this period they are uniformly 

 stout with blunt diverging extremities. The ground 

 colour of the smooth skin of the body is a very brilliant 

 pale yellow-green, becoming white on the belly and 

 ventral feet ; the segmental divisions widely banded 

 with deep purplish edged with velvety black, and across 

 the middle of each segment is a broad velvety-black 

 band, covered with excessively fine bristly pubescence 

 and bearing the orange tubercle of the upper row near 

 the front margin, and sometimes also that of the middle 

 row ; but generally this transverse black band is inter- 

 rupted by an isthmus (so to speak) of the ground 

 colour which bears this tubercle ; and below there is 

 always a slanting isthmus of ground colour bearing 

 the lower tubercle. On the third and fourth segments 

 the broad bands have only this lower interruption, and 

 bear the orange warts of the two upper rows (here 

 diminished in size) in their middle. The anterior legs 

 are white with black tips and joints ; the ventral pro- 

 legs have each a narrow streak in front, a spot behind, 

 and a large crescentic mark of black above the white 

 feet, which have dark hooks. On the anal prolegs this 

 black mark is purplish in the middle. The spiracles 

 are of a blackish-slate colour, situate within the lower 

 parts of the black bands ; the whitish belly has a central 

 series of blackish blotches and narrow transverse bands 

 in the deeply- sunk divisions. 



The pupa, when come to its full colour, is pale 

 yellow on the back and abdomen and delicate light 

 green on the head and wing covers. (W. B., 28, 2, 82 ; 

 E.M.M. XVIII, 244.)
