Agreeing with the male; ovipositor blackish, the eighth ventral segment with a small style, often only seen with difficulty. Length 5,5—7,5 mm., the latter size only reached by females with fully extended abdomen, E. univittata is not common in Denmark and has first been taken here in recent time; 0rholm, Tisvilde, on Langeland at Lohals (the author), and on Bornholm at Hasle (H. J. Hansen). The first specimen was taken on Bornholm in 1883 by H. J. Hansen, and then I have taken it on the other localities in 1909 and 1910. My dates are 22;g—13/^^^ jj. seems thus not to occur specially early. It occurs on shaded places in woods on low plants e. g. not rarely on Urtica.
