X ob. hind femora at the apex; hind tibiae not blackish at the base. The femora mainly short-haired, only the front femora with longer hairs on the posterior side, and below towards the apex; middle femora with a distinct preapical bristle; front metatarsi with short hairs below. Length 5,5—7 mm. A. diaphana is common in Denmark; at Copenhagen, Damhuss0, Charlottenlund, Ordrup Mose, Ermelund, Dyrehaven, Lyngby Mose, Fure S0, Hillerod, Tyvekrog and Praestevang at Hillerod, Roskilde, Faxe Ladeplads, Nyraad at Vordingborg and on the little island Eg- holm at Skelskor; on Langeland at Lohals; on Lolland at Maribo; in Jutland at Silkeborg and Laven near Silkeborg. My dates are " s—=^9. It occurs on bushes and in low herbage on humid places, especially in fens and at the borders of streamlets and ditches. Geographical distribution:— Northern and middle Europe down into Corsica; towards the north to middle Sweden, and in Finland. Remarks: Fabricius has in the last of his works, Syst. Antl, 1805, 270, 18, Dolichopus diaphanus, and gives as locality for it "in Americae insulis", and according to this the species should occur in America, but this is not so. It is curious to see that Fabricius in his earlier works, Syst. Ent. 1775, Spec. Ins. 1781, Mantiss. Ins. 1787 and Ent. Syst. Suppl. 1798, gives either, as in the two first "Lipsiae" as locality, or, in the last "Europae"'; only in Mantiss. Ins. he gives no locality; he evidently had not this in mind when in 1805 he gave America as locality without mentioning its occ
