the region of the spiracles yello wish-green, becoming a more 

 decided yellow stripe on segments two to four, and eleven to 

 thirteen, and running down the anal pair of prolegs ; the 

 spiracles reddish. 



Or, — ground colour of the back soft delicate grey, of the 

 undersurface greenish-white ; dorsal line paler, very finely 

 but distinctly edged with blackish threads which become 

 stronger on segments ten to twelve ; subdorsal line also pale 

 with fine edgings, and on segments one to five having imme- 

 diately below it a strong dark streak, continued backwards 

 as a dark thread. Sometimes the edgings of the lines aie 

 not so dark, but have a reddish tint; sometimes again the 

 dorsal line is not of uniform width, but at the fold froui 

 segments five to ten opens out into a small white dot, imme- 

 diately followed by a small black dot, which thus interrupts 

 the line. 



Or, — the ground colour is decidedly green, blue-green, full 

 green, or bright green, the edges of the lines red, dark red, 

 bright rust-red, or pinkish ; the dorsal line varying in width. 

 or else widened at the folds and interrupted. 



Or, — the ground colour more or less ochi'eous, sometime.'; 

 becoming as warm in tint as a piece of clean freshly-cut 

 cork; the under-surface sometimes whitish, sometimes paler 

 ochreous ; the pale dorsal line still varying in width, and. 

 though occasionally darkly margined, yet generally in this 

 variety not so distinctly defined ; in one or two specimens 

 the lines were scarcely visible. (Rev. J. Hellins.)
