head and legs being of a faint brown. The larvae were still 

 covered with fine short hairs, and appeared to have all their 

 prolegs perfect. When disturbed they roll up in a ring and fall 

 from the leaves. Having ascertained that their food-plant was 

 Ranunculns ficaria, I supplied them with this, but they seemed at 

 first to prefer R. bulbosus, though eventually they became used to 

 R. ficaria, and then would not eat halhosus. 



There was probably a moult between the 20th December and 

 1st February, but as I was away from Lewes between those dates 

 I had no opportunity of watching the larvae. 



On the 19th February the larvae were again moulting, and on 

 the 1st March were still of a green colour, though darker than 

 before their moult, with five whitish longitudinal lines, one being 

 along the centre of the back (dorsal), one on each side beneath 

 the spiracles, and the remaining two (sub-dorsal) on each side, 

 half-way between the dorsal line and the spiracles. There were 

 also two white spots on each side of every segment except the 

 head and second segment, situate between the dorsal and sub- 

 dorsal lines. The hairs had almost disappeared, but could still 

 be seen if the larvae were held up to the light. 



The next moult took place between the 18th and 28th March, 

 the larvae afterwards being of a dingy green, with numerous 

 white speckles and spots, the most conspicuous being the two 

 before mentioned, and a white one behind each spiracle. The 

 whitish hues had given place to dull green ones, those on each 

 side below the spiracles being the most distinct and lighter than 

 the others. 



There are also numerous indistinct wavy lateral lines of 

 various shades of green covering the larvae, but they are scarcely 

 visible. 



The larvae moulted again between the 3rd and 14th of April, 

 and after this moult their general appearance is brown, with a 

 green tinge. There is a darker brown diamond- shaped mark on 

 the fifth and following segments, stretching across the back of 

 the larva. The head is brown, and the second segment is 

 brown, with two dark-brown rectangular marks, with two white 

 spots on each, the marks being divided by a short whitish streak. 

 The third and fourth segments have a line of four white dots 

 circling over them, whilst the remaining segments have four 

 white spots, one being on each side about the middle of the
