THIS insect measures from two inches and a quarter to 

 nearly two and three quarters in extent. Male: front 

 wings light greenish grey, white at the base from the down 

 of the body, followed by an olive-green waved short bar, 

 this by a smaller one, and this by a third still smaller mark, 

 all three united by a line of the same colour which runs 

 along the upper margin of the wing. Hind wings clear 

 rose red, white at the lower corner, the base black, and a 

 narrow black line of variable width following the outer 

 margin a little within it; outside the line the pink is much 

 paler. 



Localities for this species are Treworles near Falmouth, 

 Worcester, Boxhill, Taunton, Isle of Wight, Coventry, 

 Scarborough, Braunton Burrows near Bideford, and Barn- 

 staple, and Formby near Liverpool. 



The situations where it is found are sandy places on the 

 coast. 



The date of the appearance of the perfect insect is June. 



The caterpillar is black, interrupted with red and dark 

 bands, in the former colotu- a double row of pale yellow 

 spots along the sides, the upper much larger than the lower, 

 a red line along the back, and a narrow one on each side 

 above the legs, which are red; head also red; the tail red, 

 its tip black. 



The date of the appearance of the caterpillar is from the 

 middle of August to the middle of September. It some- 

 times remains in chrysalis for two years. 



The caterpillar feeds on the sea spurge (Euphorbia 

 paralias}, and the cypress-leaved spurge (Euphorbia 

 cyparissias).
