and in lower montane forest on G. Mulu and G. Api in Sarawak. It is

Biology.
Bell (MS) described the larva and pupa. The larva is similarly shaped to
that of T. sinens and C. fasciata. The head is orange,
speckled olive-green, the labrum white. The body is a flesh pink with
dorsum suffused smoky brown and with a thin, dark, central line. The long
primary setae arise from white chalazae set in black patches edged with
ochre. Most setae are black, though those on the thoracic segments are
longer, white, directed forwards. Each seta bears tiny hairlets along its
length, these being longer and more numerous on the white setae.
Pupation
is in a roomy silken cell coated with soil particles, set on the ground
surface.
The host-plant was Olea (Oleaceae).
