is 24–28 mm. The length of the forewings is 10–12 mm. "Forewing pale olive brown, sometimes sprinkled with darker brown; the markings shining white, edged with blackish; viz., a small spot at base of costa, two narrow outwardly oblique transverse fasciae, a short costal mark before apex, and a straight subterminal streak; reniform stigma indicated by a swelling in second fascia; hindwing luteous white, sprinkled with grey, deeper terminally. Staudinger describes the form ''amurula'' from Amurland as rather smaller than typical olivana and darker brown; red-brown specimens are occasionally taken in England, ab. ''rufescens'' Tutt;-—in ''obsoleta'' Tutt the oblique white lines are much attenuated and the reniform stands by itself; — in ''oblitescens'' Schultz the white bands are abbreviated, one or the other not reaching the margins; - in ''confluens'' Schultz the white bands are either connected laterally by a cross streak or are approximated to form one complete or semi-complete broad white band; these last two forms are from Silesia; I have seen nothing like this development in British specimens."
