6 PAPILIO MAOHAON. 



adheres ; it is of a good size and with apparently 

 smooth surface, and when firsfc laid is of a greenish- 

 yellow colour quickly turning green, and soon after 

 tinged with violet-brownish, gradually deepening to 

 purplish, and faintly showing the embryo through the 

 shell, which in a day or two turns entirely purplish- 

 black, a process of change similar to that shown by a 

 ripening black currant. The shell next assumes a light 

 pearly transparency, and the dark embryonic larva 

 coiled round within is plainly visible, and in a few 

 hours hatches. 



The newly hatched larva is 3 mm. long, stoutish, 

 with shining black head and black velvet body with 

 dark green segmental divisions, and conspicuously 

 marked with a patch of creamy-white on the seventh 

 and eighth segments. The pale pinkish tubercles, in 

 some instances yellowish, rather bristly, are in two 

 rows down either side, and in about eight hours turn 

 dark drab, and in a day or so blackish like the third 

 row beneath, except those on the white patch which 

 remain white. 



After the first moult, in three days the length is 8 

 or 9 mm., the stoutness in proportion ; the head black 

 and the body velvety -black bearing two orange dots on 

 the front margin of the second segment ; the shining, 

 rather pointed, black tubercles having their bases red- 

 dish-ochreous, after being for a day or so green ; the 

 white patch as before, but now bearing black tips on 

 the tubercles. 



After the second moult, the length by the third day 

 has increased to 14 mm. with increase of stoutness ; 

 the black shining head is marked on the face with a 

 yellow chevron, and with pale yellow upper lip and 

 bases of papillae ; the black velvety body has the white 

 patch yet more conspicuous and encroaching a trifle 

 on the ninth segment ; the front dorsal margin of the 

 second segment is marked with orange-yellow, and
