ABSTRACT C ytological in vestigation s were made on some African Coreiods in the South-Eastern cocoa growing areas of Ghaia. Data is presented on karyotypes of the group. The now known karyotypes of the Coreoidea has been increased from 113 to 140 species by this study. E ffo rt has been ne.de to correlate information from this study with what exists in the litera tu re on morphological and cytotaxonomic studies rela tin g to the higher systematics cf the Coreoidea. Coreidae, Alydidae and Rhopalidae have been recognised as the fam ilies included in the superfamilj^ Coreoidea ( sensu s tr ic to ). The Rhopalidae and Alydidae are more closely related. The Coreidae are the more advanced forms* The Coreoidea have apparent high chromosome numbers and XY sex mechanism. The basic number is 2n=13 fo r Rhopalidae and Alydidae and 2rt=21 fo r Coreidae. C ytological features characterise some taxa but the data in others is too meagre to arrive at any conclusions. Evidence from the cytologica l data tends to support conclusions arrived at from morphological and other studies.
