. Diptera Danica: genera and species of flies hitherto found in Denmark. Diptera. Aphiochaeta. 351 height as the outer and nearer to it than to the upper supraantennal; supraantennal bristles unequal, the lower half the size of the upper or somewhat over; the upper supraantennals a little more approximate than the inner bristles of middle row, the lower still more approximate. Antennae brown or reddish brown, arista distinctly, but short-pube- scent. Palpi yellow, of ordinary size and armature. Thorax reddish yellow to brownish, dull or dullish, with brown pubescence. Pleura coloured as the disc. Mesopleura bare. Abdomen brown to blackish, dull, there is often on the second segment a more or less distinct reddish spot at each lateral front corner, and the front margin may. Fig. 105. Wing of A. rubella S • be reddish; the hind margins of the segments somewhat pale; the short hairs are distinctly a little longer at the hind margins of the segments and at the sides, but not more elongated at the hind margin of sixth segment; at the hind corners of second segment the hairs are somewhat distinct. Venter yellow. Hypopygium of medium size, brown or greyish brown, with small hairs below on the sides; the lower hinder corners are distinctly drawn out into a little point; below there is a short, flap-like, yellowish ventral plate; anal tube short, but high, yellow. Legs yellow, hind femora slightly or a little more darkened at apex, the hairs below the basal half long; bristles on hind tibise somewhat fine, smaller than in flava and of more equal size. Wings yellowish, veins brown; costa reaching to the middle, 1 longer than 2 and about equal to 2 + 3, or slightly shorter; costal cilia moderately short; fourth vein issuing a little behind the base of the fork, a little curved at the base, then nearly straight and again a little curved at the end. Halteres yellow. Female. Similar; antennae paler, red or yellowish red; hind femora likewise with long hairs below. Length 1,5—
