up and turned between the sallow leaves, but this was 

 not at all of frequent occurrence. 



When quite young the larva is rather transparent, 

 pale greenish, with a ringed appearance, owing to a 

 very distinct dull red transverse band on the back of 

 each segment, and with a dark brown head and plate 

 on second segment, which become lighter with suc- 

 cessive changes of skin. The markings on the body 

 become less defined at each change, and gradually 

 more marbled with ochreous, the red bands soon 

 losing their definite outline and becoming more 

 suffused over the whole segment, except the folds 

 where the segments unite, which remain green. 



The description of the larva in its last stage is as 

 follows : — Length about one inch ; rather stout, taper- 

 ing very slightly towards the extremities. The head 

 is rather flat, the rest of the body nearly cylindrical. 

 There is a rather striking oblique fold on the side of 

 each segment in the neighbourhood of the spiracles, 

 and the whole body has a somewhat wrinkled appear- 

 ance. The head is brown, much speckled and blotched 

 with darker brown ; the clypeus and mandibles are 

 dark brown ; the second segment with a shining, very 

 pale ochreous dorsal plate, marked with brown, and 

 having a broad darker brown dorsal band extending 

 to the subdorsal lines; the body is verdigris-green, 

 marbled with dingy ochreous, and more or less 

 suffused with pink, sometimes almost crimson, the 

 green often entirely disappearing except between the 

 segments ; the eleventh, twelfth, and thirteenth seg- 

 ments more entirely ochreous, the latter having a 

 shining ochreous anal plate, generally slightly dotted 

 with black ; a similar plate extends over the whole of 

 the hinder half of the anal clasper down to the foot; 

 the dorsal, subdorsal, and two other lines above, and 

 one just below the spiracles are greyish, and rather 

 darker than the ground colour; the line immediately 

 above the spiracles very distinct and blackish on the 

 second, third, and fourth segments, the dorsal line also
