Must be arranged close to H. Loandae. — I feel obliged to dedicate this rather curious species, of which a single specimen has been sent over from Liberia (West Africa) by Messrs. Büttikofer and Sala, to the learned Conservator of the Entomological Department of the Leyden Museum, whose intelligent activity is a sure guarantee for the prosperity of that establishment.
