64 APOROPHYLA AUSTRALIS. 



were half an inch in length. From this time they 

 fed and grew more rapidly till April, and all of them 

 had gone to earth by the middle of that month. The 

 moths appeared September 22nd to October 10th. 



The egg is full and round in shape, with about 

 twenty ribs, of which a third meet at the top, and the 

 rest stop short in the angles formed by their junction, 

 all connected by transverse reticulations ; the ground 

 colour pale yellow, but splashed with purplish-pink. 



The larvas when hatched are greenish, with a black- 

 ish tinge on the back of the front segments ; the head 

 brown ; the underside paler than the back ; the usual 

 dots distinct, each furnished with a stiff bristle. 



After a moult they become smooth, of a full green 

 colour, with a darker dorsal line and a whitish sub- 

 spiracular stripe, the folds showing yellow, and so they 

 continue to near half an inch in length. 



When this size has been attained varieties begin to 

 develop themselves, some remaining wholly green with 

 double purplish -red dorsal lines, while in others the 

 subspiracular stripe becomes edged above by a spira- 

 cular line of purplish-pink. 



At the next change the dorsal purplish-red lines 

 open on the centre of each segment, disclosing a pale 

 pinkish diamond, and the subdorsal faintly appears now 

 as a fine double pinkish line. 



The next moult produces a further development 

 quite characteristic of the adult. The larva is now an 

 inch long ; in some the green of the back is of a 

 yellower tint, and the sides a bright rose-pink; in 

 others a brilliant grass-green, and sides purplish -pink. 

 At this stage the dorsal line is flesh-colour edged with 

 pink or red, and on the front of each segment is a pair 

 of short black marks placed obliquely, so that but for 

 the dorsal line they would form a A with its apex point- 

 ing forwards ; the subdorsal line is also marked with 

 black at the beginning of each segment ; the subspira- 

 cular stripe yellowish. 



The full-grown larva is one of the handsomest and
