Male. Frons a little broader than high, black or slightly greyish 

 black and slightly shining; bristles strong. Antennæ with the third 

 joint a little elongated, brown or reddish brown ; arista short-pubescent, 

 yellow at the base. Palpi yellow with short bristles below, longer at 

 apex. Thorax yellowish red to dark brown, sometimes darker to 

 black with only two faint reddish longitudinal stripes, or all blackish 

 (var. nigrodorsata Strobl, Mittheil. Nat. Ver. Steierm. 46, 1910, 120); 

 it is almost not shining and clothed with dark brown pubescence; 

 one pair of dorsocentral bristles. Scutellum with four bristles, the 

 anterior rather small. Pleura reddish to blackish, haired as in Bohe- 

 manni and likewise with a very long bris.tle. Abdomen black, a little 

 greyish, with very narrow paler hind margins to the segments, for 

 the rest together with the hypopygium constructed as in Bohemanni. 

 Anterior legs yellow, only the middle coxæ black and the middle 

 tarsi a little darkened; hind legs black or brownish black; otherwise 

 the legs as in Bohemanni., with the hairs and bristles arranged in the 

 same way, but the middle tibiæ have only one long apical spur and 

 the hind tibiæ three. Wings as in Bohemanni and likewise with a 

 distinct bristle at the base of third vein. Halteres yellow. 



Female. Similar to the male, but without pale hind margins to 

 the abdominal segments. 



Length 2 to about 3 mm. 



As seen this species is nearly related and very similar to Bohe- 

 manni:, it is generally smaller, but not absolutely; it may, however, 

 be distinguished with certainty, also in its darkest variety, by the 

 always yellow anterior legs, paler palpi, and the much less shining 

 frons and thorax; also the apical spurs on posterior tibiæ seem to 

 yield a good character. 



P. erythronota is not rare in Denmark, Ermelund, Dyrehaven,
