Forewing highly variable in colour, but only rarely yellow ochre with contrasting dark markings (Figs 1–18); AM and PM lines usually indistinct, not thin, sharp, and contrasting; border of reniform and orbicular usually weakly defined and interrupted, or absent altogether; hindwing ground colour dull ochre to greyish ochre; male genitalia with right cornutus relatively small, i.e., length of sclerotized plate 4–5 × greater than length of free apex of cornutus (Fig. 59); female corpus bursae 5–6 × length of segment VIII, and gradually tapering to terminal sac (Fig. 64).............................................. <i>E. infumata</i> <b>–</b> Forewings yellow ochre to orange ochre with contrasting dark markings (Figs 19–30), never unicolourous grey or brown; AM and PM lines distinct, sharp, and contrasting; border of reniform and orbicular usually sharply defined and continuous; hindwing ground colour yellow ochre; male genitalia with right cornutus relatively large, i.e., length of sclerotized plate only 2–2.5 × greater than length of free apex of cornutus (Fig. 60); female corpus bursae 3.5–4 × length of segment VIII, with terminal sac abruptly tapered (Fig. 65)................................................................................................... <b> <i>E. fausta</i> sp. n.</b>
