Diptera danica : genera and species of flies hitherto found in Denmark . a and apically on theanterior side of the middle femora, and similar but longer bristles arefound on the tibiae, on the front tibiae especially on the posterior tibiae have apical spurs. The tarsi have long bristles at the apexof the joints. The front tibiae have a dense pubescence on the ven-tral side over nearly the whole length, the hind tibiae have a similarpubescence just at the apex. The tarsi are densely pubescent claws are long; there are two pulvilli and a long, bristle-shaped or nearly claw-shaped empodium. Wings with the subcostal cellopen, the cubital vein forked; between the discal cell and the upperbranch of the postical vein a postical cross-vein; five posterior cells,the fourth narrowed at the margin; the anal cell closed slightly beforethe margin. The larval and pupal stages have, so far as I am aware, notbeen described hitherto. The larva (L. cinctas) is cylindrical, yellowishwhite, finely striated longitudinally; it is about 11mm. long and 1,5 Fig. 19. Wing of L. cinctus. 38 Orthorrhapha brachycera. in diameter. It is somewhat narrowed towards each end; the lastsegment is somewhat flattened, rounded at the apex. The body con-sists of twelve segments, including the head, but at the base of thelast segment there is a short and indistinct, somewhat segment-likeswelling, if this be counted for a segment we thus get thirteen seg-ments. The head is very small and retracted into prothorax; it hasa few long hairs; prothorax beset with small, spine-like warts at thefront margin; the three thoracic segments have each a long thin bristleon each side somewhat ventrally; the last segment has eight bristles,four on the margin and four dorsal, the two near the apex, the twoothers more inwards. There is a low and not very distinct transverseswelling at the ventral front margin of each abdominal segment; theydisappear on the last three segments. The larva is amphipneus
