. Diptera Danica: genera and species of flies hitherto found in Denmark. Diptera. 4,g Orthorrhapha brachycera. below and at the apex; the upper lateral lamellge are reddish brown, they are somewhat swollen in the middle and project forwards with a blunt process and backwards with a somewhat downwards declining process; both processes are short and both are curved towards each other, thus leaving an oval opening between the upper lamellse through which the end of the penis goes; the lamelte are short haired in the upper margin. Penis is a long, simply curved thread, somewhat thickened at the base, of ferruginous colour. The eighth ventral segment is arched and points backwards with a free margin, beset with long hairs (anus hians), penis ascends from its lower- most part; above the segment forms two somewhat triangular lamellse, one on each side, beset with long and strong, black bristles; in the opening of the segment, above the base of penis and below the mentioned process a globular body is seen. Legs black or sometimes Fig. 11. , ^^^.j. j-gdclish brown; cox« grevish pru- male genitalia. . • ^ -n j- i mose; anterior lemora with medium-long hairs above; front femora with two ventral rows of somewhat long hairs; middle femora with two similar rows of short, spine-like bristles; liind femora with somewhat long bristles on the anterior and posterior side, longest on the latter side and on the anterior side present only on the basal half, and with short, strong bristles at the base on the antero- and postero-ventral side; on the latter side a dense tuft of about six very strong bristles some way from the base; the posterior femora moreover with a very dense, short pubescence ventrally. Front tibiae likewise with a very dense and short pubescence ventrally and with some bristles dorsally; middle tibiae with short, strong hairs and some short bristles ventrally, and long bristles dorsally; hind tibiae with short, dense hairs ventrally, and with longer hairs
