Claim: Epipsestis castaneata's forewings are fawn coloured and its subterminal line is extremely narrow.
Evidence: The subterminal line is pale fawn between darker shades, met at vein 6 by a thick somewhat interrupted streak from the apex. The median fascia is extremely narrow, towards the inner margin whitish and the outer line is blackish, slender, crenulate and slightly projecting on vein 4, followed by two thick brown shades with deeper centres, and then by a black lunulate-dentate line, angled above vein 5.
