A. confinis is rare in Denmark and has only been taken on two 

 occasions; Ordrup Mose (Stæger) and on Lolland at Maribo (Schlick). 

 The dates are 2o/p_u/„_ ^g Zetterstedt says: "Stæg. in litt." the 

 name is originally due to Stæger. The above mentioned specimens 

 from Stæger are his type-specimens. — Kowarz says 1. c. "Gesicht 

 und Stirn schwarz, in schiefer Richtung besehen weiss schimmernd"; 

 I have found the frons silver-white, should it be seen as black, it is 

 only when seen from in front and obliquely from below. Kowarz 

 gives also the greatest length to 6,5 mm; the species seems thus to 

 reach a greater length than my specimens, for Kowarz' determination 

 is no doubt correct. 



Geographical distribution: — Europe down into Italy; it has its 

 northern limit in Denmark, and it occurs in England; it seems to be 

 a somewhat rare species.
