Abstract
Oil palms in West Africa are periodically subject to somewhat serious attacks by Coelaenomenodera elaeidis, Maulik, a beetle of the family HIspidae, which mines the leaves. From the early stages of this beetle Mr. G. S. Cotterell, Assistant Entomologist, Gold Coast, has bred several Chalcidoid parasites, which were forwarded to the Imperial Bureau of Entomology and form the subject of the present paper.
