Bematistes umbra, the clouded bematistes, is a butterfly in the family Nymphalidae. It is found in Gambia, Guinea-Bissau, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Nigeria, Cameroon, Gabon, Angola, the Democratic Republic of the Congo, Uganda, Kenya, Tanzania and Zambia. Description . P. umbra Drury (58 f, called male but certainly a female) is a species not yet quite accurately known, which closely approximates to the preceding [ alcinoe ]. It was described by Drury from a female from Sierra Leone, in which the basal part of the forewing is dark yellow-brown and the transverse band is entirely absent; also the basal part of the hindwing is dark brown-yellow to beyond the middle with the usual black dots at the base. The female here figured as "male" thus agrees very exactly with Drury's figure and description. Another female form, fasciata ab. nov., which occurs in the Cameroons, differs in having the base of both wings still darker smoky brown, whilst the forewing bears a white transverse band, very narrow and almost broken up into spots; on the upperside this transverse band only occurs in cellules 2-6, is only about 2 mm. in breadth, forms in 2 and in 3 two free or almost free triangular spots and is placed far beyond the apex of the cell, so that the base of cellules 3-6 is broadly black; thus this female differs entirely from those of the preceding species (alcinoe). A specimen of this form was bred by Professor Sjostedt; the larva was entirely light red, somewhat inclining to violet, with black spines; the pupa is whitish with black markings and on the back of the abdomen (on segments 3-5) armed with three pairs of long, thick spines, hooked at the tips; these spines are yellow-red at the base and the two last are longer than the rest; the head bears two long, divaricating horns, distally armed with a small tooth. - A form very similar to P. alcinoe is usually regarded as the male of umbra , but differs in its larger size, the narrower or indistinct transverse band of the fore wing and the narrower dark marginal band on the upperside of the hindwing; as the transverse band of the forewing touches the apex of the cell, fills up the base of cellule 3 and has undivided spots in cellules 1 b and 2, it seems improbable that this male
