before long dons a more decided dress, dark green 

 above and pale green below. 



When about half-grown the ground colour is dull 

 greyish-green, with a dull dark green (almost black- 

 ish) fine dorsal line, a fine subdorsal line, and two 

 stouter brownish-green lines just above the spiracles; 

 belly of the ground colour, with central and two 

 side-lines running through it, faint, except at the 

 folds, where they show as strong purplish-brown 

 dashes; at this stage it is altogether duller looking 

 than when full-grown. 



When full-grown the length is barely three-quarters 

 of an inch, the figure cylindrical, tapering slightly and 

 gradually from the tenth segment to the head, which 

 is as wide as the second segment; the skin smooth. 



The ground colour is a yellowish-green, that on the 

 hinder segments beiug of a more tender tint than the 

 rest ; the back from the fourth to the ninth segments, 

 both inclusive, more or less suffused with dull brown- 

 ish-pink; the head is green with brownish bristles; 

 the second segment full green, the third dull green, 

 the dorsal line of a deeper tint of whatever colour it 

 passes through, pink through the pink, and greenish 

 after the ninth segment, and thickening almost into a 

 narrow diamond as it passes each fold ; the subdorsal 

 line is pale, often edged above and below with a fine 

 dark thread, the upper edging having a blackish dash 

 at the beginning of each segment ; the rest of the 

 side is divided by a faint pale line into two halves, of 

 which the upper is of the same colour as the back, 

 and the lower decidedly darker, and on its lower edge, 

 at the beginning of each segment, is a black or 

 blackish dash; the spiracles are reddish, and beneath 

 them runs a pale reddish stripe ; the belly is of the 

 ground colour. 



In some specimens the pink suffusion of the back is 

 confined to the five folds between the segments 4 — 

 9, and is softer in tint, and leaves the centre of 

 these segments of a tender green ; the lines and
