Varying in size from upwards of six inches across the wings to nearly
four and a half. The surface is of a greyish white, with the nervures
and posterior border black; the latter sinuated internally, and divided
by a series of large spots of a whitish colour, and generally an oval
shape; between each of the nervures, and beyond the middle of the wing,
is a longitudinal black stripe: the primary wings are moreover marked
rather before the middle with four irregular black spots, the anterior
one on the costa, the other three forming an abbreviated arched band.
The under side does not differ materially from the upper, but the black
stripes are rather broader, and there is a large irregular patch in the
discoidal cell. The body is whitish with a black line along the back,
the thorax having two black central lines and two short transverse ones
at their extremity: the breast is marked with oblique black lines, and
a row of dusky points runs along each side of the abdomen: antennæ
black.
The insect is a native of Java, Amboina, and other Asiatic islands.
