. Diptera Danica: genera and species of flies hitherto found in Denmark. Diptera. Asilidae. between the first and second ventral plate lies just under the row of muscular impressions on the second dorsal segment; the second ventral plate reaches to the end of the second dorsal; the other. ../ rl ^ /â Fig. 1. L. eylindrica. Metathorax and abdomen. 1â8 the eight dorsal segments, 1'â8" the eight ventral segments, metanotum, metastermum, M. mem- brane, U. f. upper forceps, L. f. lower forceps, V. L. ventral lamella, D. L. dorsal median lamella. ventral plates are of the same length as the dorsal plates to which they belong. The last segment is short, especially in the male. The male genitalia are somewhat swollen; they consist of a large hook- formed upper forceps the arms of which are curved towards each other at the apex, so that they leave a space between them; in this lies the median dorsal lamella directed more or less upwards between the arms of the forceps; below the upper forceps lie the lower for- ceps; the arms of the latter are somewhat bulbous at the base with hook-formed, somewhat complicated apex which is hidden between the arms of the upper forceps; below the lower forceps at the base lies the somewhat arched ventral lamella; the lower forceps and the ven- tral lamella are connected at the base. In the interior lies the penis with a long, thread-like appendage which is generally (when not retracted) curved down along the ventral lamella. The female genitalia consist of a small, generally quite hidden ovipositor. Legs not especially strong, the hind legs relatively long; the femora have only a few bristles at the apex; the anterior tibiae have some long, thin bristles on the posterior side and the hind tibiae have some similar bristles on diffe- rent sides; the tibiae have moreover some apical spurs. The tarsi have strong bristles at the sides and short bristles on the lower sur- face. The front and hind tibiae have a dense pubescence api
