Description
Ch. imperialis Btlr. male – forewing above with a straight blue transverse band, which starts somewhat behind the middle of the hindmargin, runs obliquely towards the apex, gradually narrowing anteriorly and broken up into spots; the band is 5 mm. in breadth at the hindmargin and only continuous to vein 2, then broken up into spots; the spots in cellules 3-5 contain white dots and those in cellules 6 and 7 are white, the one in cellule 7 placed nearer to the base than that in 6; the forewing is black and has in addition to these spots a white dot at the apex of the cell in cellule 4, a white dot before the middle of cellules 5 and 6 and small blue marginal spots. On the hindwing the blue band is continued to vein 2 with a breadth of about 7 mm. and placed almost exactly in the middle, covering the apex of the cell; blue submarginal spots and marginal streaks; tails short, about 3 mm. in length. On the under surface of the hindwing the black, distally light-margined transverse streaks of cellules 2-7 are placed in a nearly straight line. In the female the blue median band between vein 2 on the hindwing and vein 2 on the forewing is formed just as in the male, then follow in each cellule from 2-7 on the forewing two rounded, light yellow spots, the proximal one in cellule 4 placed at the apex of the cell; the marginal spots of both wings and the submarginal spots of the hindwing are yellowish. A rare species occurring from Sierra Leone to the Congo.
