besides the curled tail : it always stands on the edge of the leaf, gene- 

 rally on the part where it has just been eating : the fore legs are held 

 away from the leaf and move with each movement of the head in gnaw- 

 ing, as the grub takes mouthful after mouthful. It is amusing to watch 

 one of these fellows feeding, he stretches his mouth to the farthest 



point it can possibly reach, and 

 then takes mouthfuls by a series 

 of jerks, till he has brought his 

 mouth nearly in contact with 

 his middle pair of legs, he then 

 moves it slowly back again, and 

 seems to lick or plane the fresh 

 gnawed edge till he gets his neck 

 stretched to its fullest reach, and 

 he then brings it up by jerking 

 ovit mouthfiils as before. The mid- 

 dle and hind legs, as well as the 

 holders, grasp the leaf very tight 

 during the operation of gnawing, 

 which is almost incessant. The 

 head of the grub is now quite black, and its eyes are no longer to be 

 seen : the colour of the body is a dull, bluish green, with a yellowish 

 space just behind the head and another just before the tail ; it is in- 

 distinctly divided into twelve rings, and each ring has a number of 

 black warts; these warts on all the rings except the 1st, 2nd, 3rd, 

 and 12th, are ranged in three indistinct transverse rows, and on each 

 side of each ring is one lai'ger and more conspicuous wart ; from 

 each wart rises a strong, upright, black bristle, and there are several 

 of these bristles on the head itself; the last ring has a black plate 

 ending behind in two short rather hooked points. 



When about half an inch in length the grub leaves off eating, a very 

 remarkable event, for its appetite is not intermittent like that of almost 

 all other created beings, but a continued gnawing, craving, never- 

 ceasing, all-consuming propensity. The black head separates from 

 the neck and splits down the middle, and the skin of the neck also 

 splits, thus together making an opening large enough to let the grub 

 poke out his new head, which feat he forthwith performs and gazes 

 about him, moving his head slowly and majestically from side to side, 

 as though he were just landed in a new world, though a world totally 

 unworthy any expression of wonder or approval : after the head comes 

 the body, which is wriggled through the opening by tedious, laborious.
