Scand I, 262, 2. — 1862. Schin. F. A. I, 83. — 1864. Loew, Wien. entom. Monatschr. VIII, 244, 4. — 1903. Kat. palaarkt. Dipt, II, 268. Male. Frons and vertex grey; eyes not touching below the an- tennae; epistoma very narrow, white; palpi yellowish white. Occiput grey, with short, pale hairs. Antennae whitish, with a short, generally darker arista. Thorax yellow, sometimes dark yellow to brownish yellow, somewhat greyish pruinose; a darker median stripe may some- times be present. There is a yellow notopleural bristle. Scutellum only with short hairs. Pleura yellow. Abdomen dark brown to black- ish brown, with very short, pale hairs, the two last segments yellow. Venter yellow. Genitalia black, less swollen than in raptoria. Legs yellow, the end of the tarsi very slightly brownish; front coxae not so long as in raptoria, shorter than the femora. The legs haired and armed quite as in the other species. Wings hyaline, with yellowish to pale brown veins; no discal and no anal cell, both the anal vein and Fig. 103. Wing of H. oratoria. the lower branch of the postical vein wanting; radial vein longer than in raptoria; the base of the fork of the discal vein lying a little more basally than the apex of the radial vein. No stigma. Halteres yellowish white. I do not know the female; it is stated to agree with the male, as Loew 1. c. declares, that the differences in the colour of the thorax, mentioned in the descriptions of Fallen and Zetterstedt, are not present. Length 3 mm. This species is easily distinguished from raptoria by the differen- ces in the wing-venation. H. oratoria is very rare in Denmark, only one specimen, a male, has been taken in Greisdalen at Vejle in August (H. J, Hansen).
