edge white, the posterior margin bounded by a black line in all the wings 

 and continued round the apex in the superior : cilia white, blackish at the 

 base : beneath pale cinereous, wings bluish at the base, superior with 2 

 black dots ocellated with white before the centre on which is an oblong 

 spot and a transverse line of 6 or 7 beyond it, near the posterior margin 

 is a double row of fuscous spots ; inferior wings with a subcordate white 

 spot on the disc, black in the centre, surrounded by 1 1 black ocellated 

 spots, posterior margin white with 7 black spots with orange crescents 

 above them crowned by black As, the two central ones producing a white 

 patch, cilia white. Female 16 lines, blackish brown more or less variegated 

 with pale violet, a black dot on the disc, a row of scarlet spots (sometimes 

 absent) near the posterior margin ; inferior with a row of black spots near 

 the margin edged with white outside, with scarlet lunules inside edged 

 with black ; beneath ochreous brown marked as in the male but brighter. 



The females and undersides vary exceedingly. Mr. Dale has a 

 beautiful variety, and gave me two with a long curved black spot 

 margined with white on the underside of the superior wings, the 

 ends touching the edge of the inferior. Sometimes the underside 

 resembles my curious variet}' of P. Adonis. 



It is the most common of all our species, being found on every 

 heath, common, lane and corn-field, and by every roadside, from 

 the end of April to the end of August. 



The caterpillar feeds on strawberry leaves, wild liquorice (PI. 208), 

 lucern and trefoil.

14^ lines. Male pale blue, wings darker at the base, a portion of the 

 costa and a rather broad margin to all the wings as well as a dot on the 

 disc of the superior black : underside cinereous with numerous ocellated 

 spots as in P. Alexis, the marginal ocelli in the under wings alone bearing 

 small orange dots ; cilia white. 



The female of this species is unknown on the Continent. Hiib- 

 ner has figured the male, which looks like a small var. of P. Cory- 

 don, except that the fringe is immaculate. Mr. Wood's figure of 

 the British example is so different in size and colour, that I cannot 

 think it is the same as Ochsenheimer's and Hubner's.

14 to 15 lines. Deep brown, wings with a scarlet band towards the pos-

 spotted with brown : underside cinereous, superior wings with a black spot 

 ocellated with white on the disc, and a curved line of 7 others beyond it, 

 a line of large deep orange spots towards the posterior margin which is

 gined internally by black and white lunules : inferior wings more tawny, 

 Vvrith a black subcordate spot with a white ring on the disc, surrounded 

 by 1 1 others, the 2 central posterior ones united by a white patch, the 

 posterior margin orange and marked as in the superior. 



End of April to end of August, grassy places, clover and corn- 

 fields, from Yorkshire to Dorset.
