 The orange colour is slightly weaker than that of "Colias croceus" and much weaker than in "Colias myrmidone".The yellow veins in the dark outer marginal band are in "chrysotheme" recognizable on the anterior and posterior wings, whereas in "croceus" these are usually present only on the forewings tips and yellow veins are completely absent in "myrmidone".In both sexes there is a black-brown spot in the cell of the forewing upper side and on the rear wing upper side a red spot.
