This and the next species have similar, rather narrow, pale, biscuit-coloured
lightly marked forewings and yellow hindwings with a black submarginal patch. In

and irregular fascia. Both species have grey patches distal to the submarginal:
the apical one is strongest in disjungens; in discriminans Walker there is a prominent grey ellipse
at the tornus. In discriminans the abdomen has a distinctive
subapical black patch dorsally. See also the description of the previous

Bukit Retak in Brunei.
Hampson (1893) and Sugi (1987) illustrated the mature larva in colour. It is a
long, relatively slender and streamlined semi-looper that is variegated greyish
brown. The finer patterning is longitudinal banding but superimposed on this is
more oblique or transverse variegation that is coarser, blackish on A2, A3 and
A5, the latter with extensive white markings on each side that are more intense
on alternate longitudinal bands. A transverse ridge on A8 is edged darker
posteriorly. The whole effect is cryptic, twig-like. Semper (1896-1902)
illustrated a more reddish brown larva with black longitudinal striae.
