rather of a light greyish tint, finely edged above and 

 below with darker brown ; beneath this the ground 

 darkens, and is then well relieved with the spiracular 

 stripe of pale brownish-buff, edged above and below 

 with paler cream colour ; the belly and legs paler than 

 the back ; the head is cinnamon-brown, and rather 

 glossy. At this early age the identity of the larva 

 cannot be mistaken, from the subdorsal line being 

 clouded in the middle with greyish. On the 2nd of 

 October most of them had become very pale and 

 watery-looking, many laid up and waiting to moult. 

 In a day they began to moult, probably for the third 

 time, as the characteristic markings appeared, which 

 are just the same as in the adult, and at this stage, 

 after seeing them eat with avidity a leaf of Galeobdolon 

 luteum, I was content to give them all their liberty.

Plate LXXVI, fig. 2. 



On the 24th of July, 1878, I received from Mr. 

 Wm. Herd, of Scoonieburn, Perth, a batch of eggs of 

 this species just on the point of hatching, which 

 commenced immediately. 



The shape of the egg is round and domed above, 

 flattened and depressed beneath, ribbed and reticu- 

 lated; when first laid they were whitish, and lastly 

 pale grey, showing a dark grey spot at the top ; in 

 this state they began to hatch. 



The young larva eats out rather a large hole for its 

 escape from either the top or side of the shell, and in 

 many instances makes its first meal on the shell itself. 

 The larva at this time is of a faint semi-pellucid greenish 

 or drab tint, altogether very glittering; the head 

 blackish, with paler mouth, and a small darkish-brown 

 plate on the second segment, and by the help of a lens
