The venation of the wings is comparatively generalized (Figs. 551, 552), each of the principal veins usually extend- ing distinct from the others; but in some veinsVII2 and IX coalesce at the margin of the wing (Fig. 552). Vein III is four-branched ; the branches of vein V are connected with adjacent veins only by cross-veins ; and cell V^ is divided by a cross-vein. The flies are predaceous. They may be found about low bushes and on tall grass. They are somewhat sluggish, and, therefore, easily caught. The larvae also are predaceous. Some live in earth,.
