The holotypes and allotypes of all species described as new in this paper are to be deposited in the British Museum and paratypes in the United States National Museum. All the species described in this paper are parasitic in scale-insects or mealybugs.

Some of the classifications presented in these papers on African Encyrtidae are tentative only, for in the case of closely related variable species it is impossible to make final identifications on the basis of a few museum samples. The exact degrees of relationship can be expressed only when the insects are known intimately throughout their entire range and a knowledge of the limits and degrees of variation obtained. Even with this knowledge it is not always possible to make final determinations with assurance.
