Wing length: mm. fortunata + hemmingseni subgroup 9 S8 with a median pair of external basal swellings (figs 14, 20); aedeagus partly desclerotised apico-dorsally; epandrium with dorsal invaginations (character 12 above); ventral aperture small; proctiger elongate. Lampromyia fortunata Stuckenberg, 1971 Lampromyia fortunata Stuckenberg, 1971: 82—5, figs 3, 5—9; Hemmingsen & Regner Nielsen 1971: 168—75, 190—3; Frederiksen & Hemmingsen 1972. Not Lampromyia canadensis Macq., sensu Hemmingsen 1963: 237 — 67. Additional description from long series reared from larvae collected on Gran Canada by Hemmingsen (for collecting data, see Stuckenberg 1971: 85). Male Head: Face densely shining silvery-grey pruinose; proboscis black, — mesonotal length (in one specimen reaching backwards to midlength of S6); frons greyish pruinose; ocellar tubercle shining blackish; antenna (fig. 2) 1 + 2 + 3—7 + 8 + 9 + 10, bicolorous, scape and pedicel pale yellowish-brown, remainder dark sepia brown; occiput with fine, pale hairs, densely pruinose, shining silvery-grey laterally, shifting warm sepia brown dorsally except in median depression below ocellar tubercle which is greyish. Thorax: Mesonotal pattern complex; a dull golden midline stripe, separating two dark brown stripes which coalesce postsuturally into a paler brown median vitta that extends onto scutellum; these dark stripes
