22 PIEEIS DAPLIDICE. 



the glistening of the twelve or fourteen rather promi- 

 nent ribs which it bears ; in shape it is much like that 

 of an acorn without the cup and is of a bright pinkish - 

 red colour. 



In the afternoon of the 19th of August they began 

 to hatch ; the newly -hatched larva was red with a black 

 glossy head and rather glistening body, which seen 

 through a powerful lens showed minute blackish dots 

 and bristly black hairs ; it made its first meal of the 

 egg-shell, which it consumed more or less immediately 

 on emerging. 



On the 22nd I saw that many had died probably 

 from too close confinement in combination with the 

 dampness of the plant ; being such exceedingly small 

 creatures they should have been placed on a potted 

 plant, but this provision could not be made in time for 

 them. 



The survivors had been feeding, some on the blos- 

 soms, others on the leaves, in which they made little 

 holes within twenty-four hours from their quitting the 

 egg-shell ; these holes they continued to enlarge till 

 they became conspicuous, and by the end of the third 

 day (the 22nd) the larvae had grown to double their 

 size when hatched. Though they were still of a reddish 

 colour there was a yellowish-green tinge showing 

 slightly through the shining red skin ; the head was 

 still black ; there were the same black dots on the 

 body each with a black hair. 



On the 25th of August some of them were laid up 

 to moult, and on the 27th they moulted the first time. 

 The twenty survivors now fed well and grew rapidly ; 

 the head being still black. Along the back was then seen 

 a broad stripe of grey enclosing a fine whitish dorsal 

 line ; the subdorsal stripe was yellow, beneath which a 

 broad grey stripe formed the side and next was a yellow 

 spiracular stripe ; the belly and legs grey ; the tuber- 

 cular dots black, each dot bearing a short clubbed 

 hair (as though with a head like a pin) ; the ground 

 colour of the second segment was yellow, the dots
