Euproctis postgrisea Rothschild, 1920, J. Fed. Malay St. Mus., 8:131.

Diagnosis

Both sexes have a diagnostic pale whitish patch posterior to the black discal dot of the forewing, the rest of the wing being yellow, heavily suffused with black scales. Some specimens have diffuse black spots at the M1 on margin just posterior to the apex (See Nygmia castor Collenette comb.n ) but variation in Borneo is not as extreme as that illustrated for Sumatra by Schintlmeister (1994).
