Abstract

The big-headed flies, as these small insects are commonly called, are easily recognized by their very large, almost spherical head. They are small black flies four to five mm. long with wings two to three mm. longer than the abdomen. The basal cells are elongate; the anal cell reaches almost to the wing margin and is rarely incomplete. The apical cell is narrowed at the tip, but is never closed. There are three posterior cells with complete veination in all the genera except Chalarus Walker.
