70 ARGYNNIS ADIPPE. 



not quite completing the circumference a little above 

 the middle ; in the course of a week or two the colour- 

 ing changed to a greenish-grey, and by the 13th of 

 September the ribs were thus coloured and also the 

 reticulation, which made the whole egg appear of the 

 same hue ; the centre of the top of the egg was a little 

 depressed. At this date I placed them iu a cage out- 

 of-doors. 



With regard to the egg of Argynnis Adippe, Mr. 

 Fletcher has made the following observation : " I 

 think that the larva is fully formed in the egg shortly 

 after it is laid, for the egg then takes a purplish tint 

 which does not change till the larva is hatched. The 

 fact that I had two eggs for at least a fortnight with

 larva move, which larva hatched when put in a very 

 warm place, seems to support this view. 



At noon on the 14th of February, 1883, four larvce 

 hatched and were put on Yiola canina ; they were not

 fine hairs on each side of the back and sides from six 

 rows of tubercles ; the colour of the belly was a trifle 

 paler than the back. 



On the 22nd of March I received from Mr. Fletcher 

 six more larvae of the same brood, two of them had 

 recently moulted the first time; these measured 2^ 

 mm. in length, and were of a deep bright green colour, 

 the head black and with a few fine, short, black hairs ; 

 on the second segment across the middle was a narrow 

 row of dark brown tubercles, all the other segments 

 showed a dark blackish-brown dorsal v-like mark at 

 the end of each segment, these marks were shorter on 

 the third and fourth segments ; they were followed 

 outside by paler greenish, indicating the subdorsal 

 line ; the sides were of the ground colour, and above 

 the legs was a faintly paler greenish line ; the rows of
