black spots, and a row of the same alonp the hind margin. 

 Cilia of all the win<js whitish. Sexes similar. 



Under side brownish-grey. Fore wings with one or two 

 central black spots, and a row beyond, all pale-ringed ; hind 

 margin \vith a triple row of obscure blacic spots, the first row 

 the largest, the tliii'd small and invading the cilia. Hind 

 wings with a pale-ringed central black streak, surrounded 

 by about a dozen pale-ringed black spots in irregular lines ; 

 hind margin with two rows of black spots or dots. Cilia 

 whitish with blackish dashes. 



Variable in the number and size of the black spots of the 

 upper side ; those of the fore wings being often partially 

 obliterated, or, on the other hand, enlarged, lengthened, or 

 almost coalescing ; those of the hind wings much more 

 fugitive, and in some cases imperceptible. The breadth of 

 the blackish-browu margin also varies greatly, as does the 

 size of the spots of the under side. Perhaps the most rare 

 aberration which has come under my notice is a specimen 

 totally devoid of spots on the upper side, which is in the 

 collection of Mr. S. J. Capper, of Liverpool. As far as is 

 ascertained the variations are not confined to particular 

 localities, but are coincident with the range of the species. 



On the wing in June, and early in July. 



No complete history of the larva appears to exist. 



Mr. E. Dembski stated in the Entomologuts Munthlii 

 Mar/azine for 18G9, that he watched the butterflies, and saw 

 them depositing eggs on the blossoms of wild thyme (TJiyvrnf 

 aerpi/nv/m). and collected a numbei' of the eggs ; that thev 

 were oblong and destitute of ribs, and either yellow-orange 

 or white ; and that the young larva? emerged in a week and 

 fed up rapidly, exposed, on the flowers of the same plant. 

 He described these larvae as " onisciform, slightly flattened 

 on the sides, the back rather convex ; head small, black oj- 

 blackish-brown ; body gi-eenish ; dorsal and sub-dorsal lines 

 represented by a row of three black dots in the middle of each 

 segment ; legs almost imperceptible." Rut Mr. Doubleday
