u ORIENTAL ENTOMOLOGY.
T^-iiigs, and ill the green iiToration of the median vein and its branches at the base, its much smaller
hind wings, less broacUy bordered with black, in the golden green hue of its posterior wings below,
and especiaUy in the large golden orange patch at the anal angle, (which is black in O. Priamus,)
and the suffusion of the same colour along the outer margin. A variety of O. Priamus, which seems
to approach O. Poseidon very closely, is described by Dr. De-Iiaan in his fine work on the insects
of the Dutch settlements from New Guinea; another variety is figiu'ed in Freycinet's Voyage, p. 183,
f. 3. Orn. Un-illianus Guer. (Entom. de la Coquille, Ins. pi. 13, figs. 1, 2) very nearly resembles
O. Priamus, but has the green coloiu' of the wings replaced by a brilHant violet blue, with a large
hispid patch between the middle and the anal angle; the disc of the hind wings above is black, with
the veins broadly blue, dilated into an irregular subniiffginal fascia of the same colour; the uuder-side
more nearly resembles O. Poseidon, the green of the fore wings being liowever replaced by blue;
whilst the hind wings ai-e golden yellow with green reflections and with a black spot near the anal
angle, forming the innermost of a row of seven spots.
O. Tithonus, figiu-ed by De-Haan, Tab. 1, fig. 1, is a noble species aUied to O, Priamus, but having
a broad green bar along the middle of the fore wings, and the hind wings very narrow, with a broad
black anal margin.
The beautiful plant represented in the plate is the Disemma am'autia, a native of New Caledonia.
