E. medon was the first known species of Euphaedra and was described by Linne as long ago as 1763. It is rather variable in colouring, particularly the female and recalls some forms of the ceres group. In the male both wings are glossy green or bluish above, but at the distal margin more or less broadly blackish; the forewing is also broadly black inside the subapical band and has 2 or 3 black spots in the cell; the subapical band of the forewing is broad and reaches vein 3; beneath both wings are green with dark green submarginal band, 3 large black spots in the cell and a white median band on the hindwing, often broken up into spots or even indistinct; above the apex of the forewing has white fringes, but no spot. The female is much larger and has a white apical spot on the forewing and a very broad dark brown or blackish marginal band on the hindwing. - medon L. In the male the hindwing is uniform green or bluish above and the subapical band of the forewing yellow, or light bluish tinged with green and in the female the hindwing almost from the base to beyond the middle and the hindmargin of the forewing are bright blue-green or bluish; the subapical band of the forewing is bright yellow. Sierra Leone to Angola. - female f. agnes Btlr. differs in having the hindwing and the hindmargin of the forewing violet-brown above, with a light blue or violet-blue median band about 7 mm. in breadth; the subapical band on the upperside of the forewing is yellow or white. Sierra Leone to Cameroons. ab. viridinotata Btlr. has in the middle of the hindwing above a large greenish yellow spot in the green or bluish area. Gaboon and Congo. - female ab. fernanda Fruhst. differs from viridinotata in the larger white apical spot of the forewing and the much narrower yellow subapical band; the under surface is darker than in viridinotata , the white median band is more sharply expressed and the black submarginal band much widened. Fernando Po. ab. albula Thurau has in both sexes a white subapical band on the upperside of the forewing and the under surface is clay-yellow; in the female the upperside is chocolate-brown with violet reflection; the hindmarginal area of the forewing as far as vein 2 and the median area of the hindwing are bluish violet . Guinea. As fraudata Thurau describes a male from Uganda as follows: - The subapical band of the forewing is strikingly narrow, at the costal margin only about 2 mm. in breadth, at the constriction on vein 4 about 1 mm.
