. Diptera danica : genera and species of flies hitherto found in Denmark. Diptera -- Denmark. Empididae. 205 below the antennæ. The facets seem to be of equal size. There is a small incision in the middle of the inner eye-margin. There are three ocelli on the vertex, and a pair of forwards curved hairs. The. Fig. 83. Antenna of L. flavipes. x 80. antennæ are inserted near to each other, in or above the middle; they are five-jointed, the basal joints are short, the first cylindrical, the second almost globular; the third joint is somewhat elongated, conically tapering and compressed; it terminates with a long, two- jointed, apical arista, the first joint of which is very short. Epistoma is high and very narrow, or {sphenoptera) not present, the eyes here touching. There are no jowls developed, the eyes going quite to the mouth aperture. The proboscis is short, only just reaching out of the aperture. I have not been able to examine the mouth parts, which are probably similar to those in Ocydromia. Thorax is rect- angular, high, and very arched above. Pro- and metathorax small. There are short, uniserial dorsocentral and bi- or pluriserial acrostichal bristles or hairs. A notopleural and a postalar bristle generally present, sometimes also a supraalar bristle, and there may be other small hairs present at the sides of the disc. Scutellum has two or a greater number of marginal bristles. Metapleura with short, fine hairs, or {sphenoptera) bare. Abdomen is slender; it consists in the usual way of eight segments, the last is small or hidden. The male genitalia form a smaller or larger forceps with unsymmetrical arms, between them a thin, sinuous penis curves upwards. In the female the eighth segment forms generally a long, compressed, sword-shaped ovipositor, which at the apex bears a small joint, terminating with a pair of thin styles; in sphenoptera the eighth segment is shorter, conical, not compressed, but likewise with a joint with two styles at the apex.
