Western Blue Charaxes

Ch. smaragdalis Btlr. Both wings above from the base to the apex of the cell black with greenish or bluish reflection, then follows in the male a blue half-band, about 10 mm. in breadth, between the hindmargin and vein 2 or 3 and in each cellule from 3—7 two very widely separated spots, all blue except the distal ones in cellules 6 and 7; in the female there is in the middle a white transverse band, 7 mm. in breadth, running obliquely from the costal margin towards the hinder angle and reaching vein 1; the outer row of spots, which runs almost parallel with the distal margin in the male, is almost identical in the female. The hindwing has behind the apex of the cell a blue transverse band 12 (male)—15 (female) mm. in breadth and is black at the distal margin with blue-white submarginal spots and marginal line. The under surface is dark grey-brown, marked almost as in bohemanni. Niger to Angola and Uganda. — The blue transverse band on the upperside of the hindwing is narrower and everywhere completely separated from the blue marginal line. Sierra Leone to the Gold Coast.
