Deltote bankiana, the silver barred, is a moth of the family Noctuidae.
The range of the species stretches from the Iberian Peninsula and France in the west to Japan and Korea in the east.
"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.
