lines in length, of a light rather greenish-drab colour, 

 and on the 18th they moulted, and ate freely of knot- 

 grass as well as plantain. Before moulting I had 

 observed that they had a paler subspiracular stripe, and 

 now, after their moult, this was very distinct, and 

 their backs were green, having paler, almost whitish, 

 dorsal and subdorsal lines, these last the thickest, 

 and both of them finely edged with darker glaucous 

 green than the ground ; a darker glaucous green 

 freckling ran along the spiracular region ; their heads 

 a pale greenish-brown. They all by degrees grew 

 paler, and their lines indistinct as they drew near 

 another moult, which was accomplished on the 23rd 

 and 24th, when they were now half an inch long, and 

 their characteristic dress appeared for the first time — 

 an appearance only too familiar to those who have 

 paid much attention to larvae. This dress of course 

 was only somewhat rudimentary, but the subdorsal line 

 having a faint clouded central streak through it, and 

 a darker mark above it at the beginning of each 

 segment was quite sufficient for their satisfactory 

 identification. On the 27th and 28th they moulted 

 again ; though greenish at the time of casting their 

 skin, yet in half an hour their colouring was grey, the 

 head remaining pale green some hour or two longer, 

 when it also began to grow a little greyish-brown, and 

 to show a darker streak of reticulation down the front 

 margin of each lobe ; the black dashes along the upper 

 margin of the subdorsal pale stripe being very strongly 

 marked; twelve hours later their grey colouring 

 changed to brownish-grey. On the 29th and 30th, 

 and 1st of October they again moulted, one of them 

 nearly black, one light green, the others pearly-grey 

 at first turned rather pinkish-grey, and after moulting, 

 they were about an inch in length, and stoutish in 

 proportion. On November 15th they were all dead 

 but one, from some disease which turned them black 

 and rotten. The sole survivor on the 25th changed 

 to a pupa. (W. B., 1873, Note Book II, 132.)
