16 AGBOTIS CINEREA. 



they moulted a second time, and were now of a deep 

 green colour, with rather lighter green dorsal line, 

 distinct from having dark edges ; the shining head 

 with a black mark on the lobes, the ocelli, and the 

 mouth ; the subdorsal line and the other below it 

 now show faintly of lighter green, and the paler spi- 

 racular stripe is plainly visible, the raised black dots 

 and hairs very much so. The larva is now 7 mm. in 

 length. On the evening of the 5th July two had 

 moulted for the third, time, and the remainder by next 

 day. From this time they began to thicken, and by 

 the 11th showed a further moult to be not far off. On 

 the 13th they were laid up waiting, and on the 17th 

 ten had moulted the fourth time, and three were still 

 waiting. On the 9th August the largest seemed pre- 

 paring for another moult, and in the afternoon of the 

 13th it moulted the fifth time ; two others were then 

 laid up, and the rest were still feeding. Another 

 made its fifth moult on the 16th, and others were laid 

 up ; one moulted a fifth time on the 17th, and one 

 was preparing on the 21st. On the 29th the three 

 smallest, a moult behind the others, died ; and two 

 others, of the same size and moult, died on the 3rd 

 of September. The four survivors attained full 

 growth, and were fine plump larvse by the end of Sep- 

 tember ; they continued to feed well up to the 10th of 

 October, when one was found hibernating, not having 

 fed for three days ; two others during that time had 

 fed but very little, and only one was still feeding well 

 as ever, a ? as I suppose from its being the largest. 

 I put them all four in a pot of Thymus serpyllum, 

 prepared for them, and protected by wire gauze to 

 prevent their escape. (W. B., 1882 and 1883, Note
