indeed sometimes wholly disappears, leaving the fore wings 

 of a smooth even purple-brown or purple-red, darker or paler, 

 when also all the markings are even less distinct, except the 

 subterminal line which is neaj-ly always conspicuous and 

 usually of a lovely yellow. A series of such specimens of 

 unusual richness is in the collection of Mr. W. H. B. Fletcher. 

 In Mr. F. J. Hanbury's collection is a specimen of a dull 

 dark purplish-red without a trace of any of the pale markings. 

 In Ireland the range of colouring appears to be even greater 

 than with us — red, red-brown, purple-red, even brown and 

 ashy-brown in various tones, purple-grey or purple-slate ; 

 and Mr. Kane records one specimen from the Bog of Allan 

 having the dark red-brown colour of Eurois adusta. In the 

 West of Scotland many specimens are tinged with greyish- 

 blue. Mr. P. M. Bright has one from the east of that 

 country of a very pretty pale purple-grey mottled with brown 

 and black markings; and two others of a bright clay-red 

 totally devoid of markings, except the subterminal line, which 

 is very broad and conspicuous. 

 On the wing in June and July.
