A small number of Haematopota from the Congo were recently sent for determination to the British Museum by M. E. Roubaud of the Pasteur Institute. Among these were specimens of an interesting new species of the H. pertinens group, and as M. Roubaud was kind enough to say that the type of this species might be deposited in the British Museum, I undertook to describe it, including at the same time, at Dr. G. A. K. Marshall's request, descriptions of a few of the numerous unrecorded African species of this genus in the collections of the British Museum and the Imperial Bureau of Entomology.
