 in ruficornis. Halteres yellow. 



Female. Similar; antennæ a little smaller; scutellum with four 

 equal or nearly equal bristles; abdominal tergites not shaped as in 

 ruficornis, at most somewhat narrowed; abdomen has no bristly hairs

A. errata is not rare in Denmark; Damhusmosen, Ermelund, 

 Holte, Ørholm, Suserup Skov at Sorø, on Langeland at Lohals and in 

 Jutland at Hejls and Skamling south of Kolding, Nebsager and Ry 

 (H, J. Hansen, Th. Mortensen, the author); my dates are V5 — ^Vs; 

 a pupa was taken at Damhusmosen in flood refuse in May 1879, it 

 developed soon after (Schlick), and this is the first known Danish 

 specimen. 



Geographical distribution: — Besides from Denmark the species 

 is known from England and Holland.
