with t«o large wliite spots, one near the base and dorsal 

 margin, the other beyond it, larger, and nearer the costa ; 

 cilia black, tipped with white near the anal angle and apex. 

 Hind wings shining black, also with two large white spots, 

 one toward the dorsal margin near the base, the other in the 

 middle ; cilia black, tipped with white. Female similar but 

 rather smaller ; body shorter. 



Undersides of all the wings gloss}' black, with the same 

 large white spots, but that one lying near the dorsal margin 

 of the fore wings is continued as a white cloud to the base, 

 and those on the hind wings are almost united. Body black, 

 sharply barred with white. Legs white. 



Usually not variable, but in some districts, particularly ia 

 the West, a form having also a small white discal spot on the 

 fore wings is not uncommon. 



In the collection of the late 3Ir. Henry Doubledaj*, in 

 Bethual Green Museum, is a singular and beautiful specimen. 

 On its outer, usually black, area, beyond the large outer 

 white spot on both fore and hind wings is a series of white 

 streaks, and below these a large sharply defined white spot 

 above the anal angle, thus furnishing it with a dazzlingly 

 pretty outer border. 



On the wiug in May and -lune, and sometimes to the 

 beginning of July. OccasiouiiUy — I tliink rarely^there 

 are indications of a second general ion. for instance, I took 

 in Surrey a specimen on Septembei- 1, IsGo, and several in 

 August 1861, but it remains uncertain whether these were 

 the progeny of the individuals that had been on the wing in 

 May, or merely produced from delayed pupje. Mr. J. -J. 

 Walker took specimens in Galway on June 30, which he 

 referred to a second brood. On the other hand, Mr. 

 W. K. Jeffrey reared in July the moth of one of his larv.u 

 of the previous August.
