E. harpalyce Cr. Both wings above uniform black-brown, with small white apical spot on the forewing and a bright blue transverse band on the hindwing, which is broad at the anal angle, anteriorly becoming narrower terminates at vein 6 or 7 and is sometimes continued more or less far on the forewing also. The under surface is rather uniform light green or grey-green with 1–3 black dots in the cells. In the type-form the subapical band of the forewing is entirely absent in the male and very narrow and yellowish in the female. Sierra Leone to Cameroons. In ab. lakuma Btlr. the subapical band of the forewing is very narrow in the male but in the female 4–5 mm. in breadth.

The under surface is green with one black dot (occasionally 2 or 3) in the cells and two dull, dark, not very distinct transverse bands beyond the middle; the subapical band of the forewing only shows through faintly. The female may attain an expanse of 100 mm. and is the largest of all the Euphaedra species. Cameroons to the Congo and Uganda.
