THE GENUS CRESSOCHILUS BANKS (HYMENOPTERA, POMPILIDAE)
Banks distinguished Cressochilus from other genera by its having a somewhat acute marginal cell and the apical margin of the clypeus biconcave. In the females the biconcave margin of the clypeus may be very weakly indicated, but in the males it is usually stronger, there being often a well-marked median tooth.
