Archive image from page 210 of Diptera Danica genera and species Diptera Danica: genera and species of flies hitherto found in Denmark dipteradanicage01lund Year: 1907 Asilidae. 99 metathorax is rather distinct; on the ventral side there is a large metasternum, the space between it and the hind coxae is mem- branous. Abdomen long, somewhat flat, consisting of eight segments; the first dorsal segment is short, the second the longest; on the ven- tral side the first segment is very small, the following of nearly equal length. The male genitalia I have only been able to examine in situ; so far as I could ascertain there is an upper, triangular plate, following after the eighth segment; below and to each side of this plate there is a large pair of forceps, each arm of which has an outer, rounded branch, and an inner branch which is longer than the outer and forked at the end, the upper arm of the fork being directed upwards, the lower Fig. 11. D. teutonus, front leg. XS. downwards; I think this forceps answers to the lower forceps; below there is a long ventral lamella terminating in a pair of lamelliform styles. The female abdomen terminates in a pair of small lamellae. Legs not especially strong; front tibiae on the ventral side produced in a strong spine, the apex of which is bent strongly outwards; the base of the front metatarsi has an obliquely cut part turned towards the spine and this part and the inside of the spine are both serrated (Fig. 11). The legs have some strong, spine-like bristles which are short on the femora, longer on the tibiae: the posterior tibiee have apical spurs. The tarsi have strong spine-like bristles at the ends of the joints, the metatarsi over the wiiole length. Front and hind tibiae have a short dense pubescence on the ventral side apically, it is most
