This species is common in many places throughout Southern 

 and Central Europe, and the Mediterranean Region; and in the 

 southern parts of its range it is much more widely distributed, 

 and much more variable than in the north. It is found, 

 frequently with P. corydon, chiefly on a chalk or limestone soil, 

 and as a British insect, appears to be confined to the south 

 of England. It is, I believe, still to be taken abundantly in 

 certain localities close to Brighton, where five species of this 

 group, Polyommatus corydon. P. thetis, P. icarus, P. alexis, and 

 Zizera minima, may all be found flying together. Wherever I 

 have been collecting on the Rhine, at the right season, I 

 have found P. thetis fairly common in the flowery meadows 

 on the banks, where P. corydon, when it occurs at all, is 

 scarcer ; but I never saw P. thetis far from the banks of the
