. Diptera Danica: genera and species of flies hitherto found in Denmark. Diptera. 200 Phoridae. costal cilia long; fork longish, angle somewhat acute; fourth vein issuing considerably behind the base of the fork, somewhat curved at its origin, curved upwards at the end and ending considerably before the apex of the wing. Halteres Fig. 75. Wing of B. umhrimargo q . Female. Antennae with the third joint smaller; palpi of the same size and armature, and the female for the rest similar to the male. Length 1,8—2,6 mm.

B. umhrimargo I have taken only in one locality, Ermelund, but here it is rather common, occurring on leaves of bushes and low herbage in a low, damp place; my dates are ""U—^"/e so that it seems to be an early occurring species. I have taken it in copula on ^^U. I took it for the first time in 1914. Geographical distribution: — Europe with Britain and down into Austria; it does not seem to be known north of Denmark. 10. Apliiocliaeta Brues. Species of small to medium size (about 0,5 to fully 3 mm). Frons generally broader than high, sometimes quadratic or higher than broad; it has an impressed longitudinal middle line; there are three transverse rows of bristles with four bristles in each row; the two posterior rows are generally more or less straight, or the middle row may be somewhat convex; the anterior row varies from straight to very convex, with the inner bristles much below the outer, in extreme cases nearly or quite vertically below the outer. There are two pairs of stronger or weaker supraantennal bristles, one below the other, which are proclinate, directed forwards and downwards; these two pairs of bristles are either equal in size or the bristles of the lower pair are smaller and weaker than those of the upper, in various degrees, down to a quite minute size, and in rare cases the lower.
