. Fig. 30. Wing of D. festivus c?. and one postero-ventral bristle. Hind tibiæ with two dorsal rows, one ventral bristle towards the apex, and a ventral row of small bristles; middle metatarsi with one bristle above, hind metatarsi with about three bristles above, some anterior and small ventral bristles. Wings yellowish or light brownish tinged; veins black or blackish brown, costa with a somewhat large, elongated swelling; discai vein with a large, distinctly angular, but somewhat obtuse bend; axillary lobe somewhat well developed, anal vein going somewhat downAvards. Squamulæ yellow, with a black fringe. Halteres yellow, Female. Epistoma broad, greyish white. Antennæ a little shorter than in the male, third joint very short, Abdomen black-haired at the sides. Legs with the front coxæ generally more black-haired; front tarsi simple and hind femora not fringed. Wings without costal swelling. Length 5—6 mm. This species is in the male easily distinguished from trivialis by the shorter antennæ and the bristles on the front tarsi; the female is less easily distinguished, but is known by the much more yellow and a little shorter antennæ, and the larger bend of the discai vein; the species also is larger. D. festivus is in Stæger (1. c.) noted as not rare from July into October on bushes and hedges; in my experience it is a rare species, and I have only once taken a single specimen. We have in all eight specimens in the collection, taken on Vester Fælled (Stæger), at Faxe
