The form of the more typical members of this family is well shown by the common House-fly. But the family is a very large one and includes species that differ greatly in form. These differences are so great and so varied that some writers divide the family into nearly thirty families. It seems to us, however, to be better to consider these divisions of subfamily value. The following characters are presented by the family as a whole. The antennae (Fig. 586) are three-jointed ; the third seg- ment bears a dorsal bristle. The frontal suture is present (Fig. 587). The proboscis is always present. Vein II of the wings may be present or absent; vein III is three- branched ; cells V, and V3 are wanting ; the branches of vein VII coalesce with the adjacent veins (VII, with V3, and VII, with IX) for nearly their entire length. The pulvilli are present, and the empodia are never pulvilliform. As this family includes more than one third of all the known Diptera, it usually happens that a large proportion of the flies in a collection belong to it. It seems necessary, therefore, to indicate some of the principal divisions of the.
