They are also found in decaying wood, and are supposed to be carnivorous. The family is a very small one. The most common species is Scenopimis fenestfalis (Sce-nop'i-nus fen-es-tra'lis). Family Empidid^ (Em-pid'i-dae). The Dance-flies. The dance-flies are of medium or small size; they are often seen in swarms under trees or near shrubs and about brooks, dancing and hunting. The family is a rather diffi- cult one to characterize owing to great variations in the form of the antennae and in the venation of the wings. The branches of vein VII coalesce with the adjacent veins (VII, with Vg and VII^ with IX) from the margin of the wing towards the base for a considerable distance (Fig. 569). In most of the genera this coalescence is carried so far that the free parts of the branches of vein VII appear.
