The present catalogue consists of a taxonomic revision of the Sphingid fauna of the Ethiopian Region, with descriptionptions of a number of new genera, species and subspecies as well as detailed descriptionptions and records of all the species known to occur in Ethiopia, Somalia, Socotra, the Sudan, Kenya, Uganda and Tanzania. For reasons of economy the genitalia and early stages have only been descriptionbed and figured if previously undescriptionbed, or if of special importance. Illustrations of all adult moths belonging to new species or subspecies and of all species not previously figured have been appended, as well as of many others of special interest. Details of illustrations of African Sphingids in other publications are given in the index. A more natural classification than any available hitherto has been proposed, based mainly on a more complete knowledge and understanding of the genital armatures of both sexes and on the early stages.
