H. vitripennis is rare in Denmark, I possess only a few males I 

 and two females; Holte (Rosenberg), on Bogø south of Sealand and 

 in Jutland at Hejls south of Kolding and at Jelling (the author); ij 

 my dates of capture are ^V? — ^V? in 1917 to 1921. Rosenberg bred

Geographical distribution: — Europe, towards the north to

 supraantennal bristles present, only in the male of daiici wanting. 

 Eyes hairy. Antennæ in the male of characteristic shape, the third
