deeper tint of the same ; second segment bright transparent 

 yellowish-green, and near the end of this two subdorsal 

 yellowish stripes begin to appear as mere lines, broadening 

 in the following segments and becoming broad opaque 

 primrose-yellow stripes, edged above by a narrow, trans- 

 parent green dorsal stripe, and below by another such stripe, 

 meltincf off into srreenish-white on the undersurface ; anal 

 flap sulphur-yellow ; spiracles small and pale ; skin glossy ; 

 raised dots either of the ground colour, or tipped with green 

 on the yellow stripe. When quite full-fed it loses its dis-

May and June, on thistle, bramble {Ruhus corylifoliua), 

 Stachijs sylvatica, knapweed, sorrel, coltsfoot, strawberry, 

 plantain, buttercup, and other low-growing plants ; feeding 

 under a slight web on the underside of a leaf. There seems 

 to be no evidence as to the condition in which the winter is 

 passed — whether in the egg or as a young larva. 



Pupa broadest across the thorax, which is well formed ; 

 wing-covers of moderate length ; leg- and antenna-cases a 

 little longer and free at the end ; the fixed segments of the 

 abdomen slightly keeled at the back, and having very large 

 spiracles, while those on the movable and tapering segments 

 are of ordinary size ; each segment has five or six transverse 

 ridges, the most prominent being at the hinder edge ; cre- 

 master pointed and flattened, furnished with curly-topped 

 converging spines ; dull black, glistening a little on the 

 back, and becoming glossy on the two hinder segments. In 

 a cavity formed by folding down the side of a leaf or joining 

 two leaves, in an oval cocoon of thin, but strong, white silk. 

 (W. Buckler.) 



The moth flies commonly late in the summer among 

 rough herbage, especially among thistles, on hill-sides, 

 coarse pastures, quarries, and rough ground generally, and 

 looks verv white as it flits about in the early dusk. During
