spot. Occasionally, the blotch is much reduced in size, but it 

 is usually large, and sometimes there are indications of a dusky 

 stripe from it to the inner margin. 



When freshly laid, the egg is whitish, but changes to pale 

 orange. The caterpillar (Plate 92, Figs. 2, 2a) is greenish, with 

 more or less connected reddish marks on the back, or green 

 inclining to yellowish, or bluish, without markings. It feeds 

 through the summer on flowers of ragwort, knapweed, scabious, 

 yarrow, golden rod, etc.

 May to August, and specimens of a second brood occur in 

 September and October. 



It is widely distributed over the British Islands, but in

 whitish grey, with several dark-grey bands (Plate 93, Figs. 

 76,10$). 



In var. hebudium^ Sheldon, from the Hebrides, the usual 

 reddish stripes are replaced by narrower dark-brown ones ; the 

 space left by the reduction in width is white, giving the insect a 

 decidedly grey appearance. 



The caterpillar lives in the flowers of the foxglove {Digitalis 

 purpurea) and feeds therein upon the stamens and the 

 immature seeds. It enters by boring through the side walls, 

 and then secures the longer lobe of the blossom to the shorter 

 upper one with a few silken threads. Tenanted flowers have
