Hypocera. 175 



Female. Antennæ a little smaller than in the male, and clypeus 

 more distinctly protruding; wings with first costal division relatively 

 shorter. 



Length 2,4 to nearly 3 mm. 



H. agilis is rare in Denmark, I have only taken it at Lohals on 

 Langeland and at Hejls south of Kolding on ^^/v — ^V? in 1919 and 

 1920, further one specimen from Bornholm at Rønne in July 1883 

 (H. J. Hansen); at Hejls it occurred on biishes of Corylus along a 

 road together with H. carinijrons\ as mentioned, we have moreover 

 an old female specimen from Stæger, placed as female to carinifrons 

 and probably from the vicinity of Copenhagen. 



Geographical distribution: — All Eiirope, towards the north it 

 seems to occur to the southern Sweden.
