stripe. Mr. C. A. Briggs has a specimen in which the crimson 

 costal stripe is joined to the apical spot ; while in Mr. A. 

 Robinson's collectioa is oae having the crimson stripe further 

 continued in a more sltxider form along the hind margin to 

 the lower spot. Mr. J. J. F. X. King possesses one which 

 has a black streak running inward from the margin of the 

 hind wings near the anal angle. 



On the wing at the end of May and in June. 



Larva plump, cylindrical, tapering slightly at each 

 extremity, head rounded, black ; body regularly ringed 

 throughout with bright yellow and purplish black ; the an- 

 terior half of each segment being black streaked with purple, 

 and the posterior half yellow ; the whole thinly sprinkled 

 with delicate hairs ; legs, pro-legs, and tip of anal segment, 

 black. 



July and August; on Senecio jacohcra and S. vulgaris 

 (ragwort and groundsel), often feeding gregariously in the day 

 time, devouring leaves, buds and flowers, and reducing the 

 plants to mere stumps. Occasionally on other species of 

 Senecio, and has been found feeding freely upon Tussilago 

 farfara (coltsfoot). 



Pupa short, stout, blunt, and without hooks or spikes ; 

 uniformly dark reddish pui-ple. Under moss or rubbish of 

 any kind close to or beneath the surface of the ground, or in 

 holes in a dry wall ; forming scarcely any cocoon ; passing the 

 winter in this state. 



Kather a sluggish insect, sitting about on its food-plant 

 and other low plants, and especially in bushes, in the daytime, 

 but flying readily when disturbed, and, from its bright colour, 

 very conspicuous when on the wing. Flying of its own 

 accord in the evening and early part of the night, and 

 coming very eagerly to a strong light. When captured it 

 feigns death and may be rolled about in the hand, or picked 

 up by a wing, or a leg.
