A. circumdatus is somewhat rare in Denmark and hitherto only 

 found at Tisvilde and Odsherred (Schlick, the author) and in Jutland 

 at Bulbjerg (Th. Mortensen.) My dates are ^^7—^/9. It occurs toge- 

 ther with A. fenestratus in the same localities as this, flying in the 

 sunshine, but it is generally present in smaller numbers. 



Geographical distribution: — Europe down into Spain and Italy; 

 towards the north to middle Scandinavia.
