Larva variable geographically and individnally : head red, with or without a 

 black patch on each side above ; pronotal shield generally red in middle, a red 

 dorsal line, sometimes replaced by a grey one, seldom vestigial ; a row of dorso- 

 lateral rounded spots, yellowish white or reddish, below it there is often another 

 series of smaller spots ; a dorso- and a ventro-lateral yellowish band, often absent ; 

 ground-colour very variable, from yellow to black, tlie dark forms mostly finely 

 (lotted with pale yellow or grey. — Food-plant : Euphorbia. 



Pupa rather stout, clay-colonr.

The caterpillar is a very interesting subject for the study of tlie evolution 

 of pattern. A long series of each brood from the various countries should be 

 compared. The absence of the second lateral row of spots from some geographical 

 forms is a curious feature.
