These are sometimes known as the Tangle-vein flies, be- cause of the complex wing venation. The antennas are small and the proboscis rather elongate; the female has a long ovipositor. The adults are flower frequenting and quite rare. The early stages are not well known. The larvae of one species are parasitic on a beetle. 230. Rhynchocephalus sackeni Will.
