 These were "Descriptions of new species of Diurnal Lepidoptera From Madagascar" and "Descriptions of new species of African Diurnal Lepidoptera" (butterflies in this last work are depicted in Part 3 of "African Lepidoptera" but the text is omitted).This well-illustrated, rare work is an important contribution to the knowledge of the East African butterfly fauna as it contains descriptions of 55 new species chiefly from Madagascar, the Cameroons, Old Calabar and Ribé (East Africa).The now extinct Seychelles parakeet, "Psittacula wardi" was named in his honour.
