M. velutimis is not common in Denmark, or it has at all events 

 hitherto not been taken frequently; it was for the first time taken in 

 1882; Amager, Ordrup Mose, Lyngby Mose (the author). Nøddebo 

 (J. C. Nielsen), and on Falster at Resle (H. J. Hansen). My dates 

 are ^^k—'^^le, it is thus an early species. It occurs both in or at 

 woods and on fields, often in the vicinity of water. I took it in copula 

 on 31/5. 



Geographical distribution: — Europa down into Italy and Spain; 

 towards the north to southern Sweden.
