E. trajanus Ward (29 f). Ground-colour of both wings black; the forewing in the above and beneath with a yellow-brown basal spot, a light yellow transverse band across the middle, a curved row of seven submarginal spots, of which the anterior ones are larger, and two or three small white spots before the apex; the hindwing above is bluish white in the middle and has small white dots close to the distal margin; beneath it is black with deep black rays between the veins and narrowly red-brown at the base. The female has white markings and the basal part of the hindwing on both surfaces is white to far beyond the middle and from the inner margin to vein 7; the black marginal band is consequently much narrower than in the but encloses two rows of white spots. - In West Africa from the Niger to Angola.
