forewings are somewhat browner than in loreyi and roseilinea, with
CuA in the cell standing out paler but without a distinct pale spot at the
discal end. In the male genitalia the cucullus is rather elongate, and the harpe
has a distinctive, apically bifid spine arising from the ventral margin of its
tropics to Fiji and New Caledonia.
M. separata and M. loreyi, this species has only
been taken at 2600m on G. Kinabalu, a single specimen.
(1945) described the larva. Early instars are initially grey, becoming green
when feeding, moving with a slight 'semi-looper' motion. The head is honey-colour.
There is a broad, double, purple-brown dorsal line, and a broad sublateral of
the same colour. The sublateral and ventral area is whitish. Later instars
become browner, with minute dark markings on a pale creamy yellow ground-colour.
There is a pale dorsal line edged by a dark brown line then, successively, lines
of pale purple brown, ground colour, purple-brown, ground colour, a narrow
brownish orange stripe edged purplish brown, ground colour, blackish-brown
centred with orange-brown, broad white centred with olive brown. The underparts
are pale olive brown.
The larva has been
recorded from various grasses and also rice (Oryza) (Robinson, 1975).
