preference. Only six specimens have been taken in recent surveys, three
from partially disturbed alluvial forest by the S. Melinau near G. Mulu, one
from lowland forest in the Barito Ulu of Kalimantan Tengah, and two from stunted
hill forest at 900m on Bukit Monkobo in Sabah.
The larva, described by Gardner (1947) and Bell (MS), is typical of the genus in
proleg development and possession of tubercles on A8. The head is dark brownish
red with white markings, and there is an oval or triangular yellow spot on each
side of the vertical sinus. The body is pale pinkish brown with darker suffusion
laterally on A1, A2 and A7. On A1 there is a vinous red patch in front of this
suffusion. There are 30 dark brown parallel lines running the length of the
body, each broken into short sections, dots and spots, those in the spiracular
region more intense, also the dorsal and subdorsal ones, these tending to form a
series of ovals down the body. The tubercles of A8 are deep vinous red. The
ventral surface is pale with black and red or just red patches (the posterior
two) between the prolegs.
