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 ni 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, Polyonunatus corydon.^ P. theiis, P. icarus, P. alexis, and 

 Zizera ini7iiiiia^ 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. corydo?t, when it occurs at all, is 

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