female of the same species. Malloch has 1. c. already stated that the 

 male to rufa has only two scutellar bristles. I have compared my 

 specimen with a male of nibra Schmitz, kindly sent me from the 

 author, and I have no doubt that also this species is identical with rufa. 



A. rufa is rare in Denmark, I possess only one male and one female, 

 taken in copula, Holte ^Ve 1917 (Th. Mortensen), but in Stæger's 

 collection there are an old male and female, determined as flava. 



Geographical distribution: — Besides in Denmark the species 

 occurs in Britain and middle Europe going down into Styria {pallens, 

 Schmitz, Ent. Ber. Nederl. Ent. Ver. V, 1919, 187).
