Ornithopterus aUs fusco-nigris ; anticis fascia lata abbreviata cui'vata submediana (e maculis 4 constant!) ;
maculisque 9 submargiualibus (4 anticis elongatis), albidis ; postlcis pone medium macula magna irregulari subalbida,

Ornithopterus witli black-brown wings ; the anterior having a rather broad oblique very pale buff bar across
the discoidal cell, near its exti-emity, beneath which ai-e three other h-regular spots of the same coloiu- ; followed by
nine submargimal spots of the same colour, the four anterior of which are elongated ; the hind wiiigs' are marlced
beyond the middle with a large dU-ty whitish-buff patch, divided by the vems, extending to the anal angle, and bearing
four smaller dark-brown spots. The mngs on the underside ai-e coloui-ed as above, the coloui- of the pale
marking of the hmd wings being clearer, with a yellow shade beyond the dark spots. The thorax has a short
brilhant gi-een dash on the upper side, and the sides beneath the wings are brilKant crimson. The abdomen, above,
is dirty buff ; beneath, golden yellow, with black dots (Female).
S I N C E tlie pubKcation of the last Part of this ^rork I have heen favoured, by W. H. Ince, Esq., with
an opportunity of figuring the female of the beautifiil species of butterfly, the male of which is presented
in Plate XI., which was captiu-ed by his brother, Commander J. M. R. Ince, of the Eoyal Nai^,
who has furnished the following particulars relative to its capture " This large butterfly came from
Cape York, N.E. Cape of New Holland. It is common at Darnley Island, Torres Straits ; the natives
decorating theii- haii- with them, but more especially with the males. [PI. XI.] I procured the
specmen figured in Plate XIV., in February, 1845, when in RM. ship My. I had a very beautiful
specimen of a male, which I caught dm-ing the September preceding, but I gave it to my friend,
W. M'Leay, Esq., of Sydney. They were caught within fifty yards of the beach, near the fresh water
lióles."
The female above described difl-ers from the female of Orn. Priamus (Panthous, Clerck. Icon, t 19)
in having the dark coloiu- of the upper surface of the wings of a uniform tint, not darker along the
apical margms, in the large oblique patch traversing the discoidal cell of the fore wings, and in the
pale spots of the hiud wings extending to the anal angle. An insect, which scarcely differs from the
tcmale here figxu-ed, is represented by Boisduval, in the Entomological Plates of the Voyage de
Astrolabe (PI. IV. fig. 1 & 2). It is from Celebes, and is given in the Species général des Lépidoptères,
as a variety of Orn. Priamus.
The following is Dr. De Haan's description of the male variety of P. Priamus, mentioned in a preceding
page (24), from the South-West coast of New Guinea, which seems to be very nearly aUied to
O. loseidon, male. I am indebted to Dr. Horsfield for a translation of De Haan's description. It
Jias the hmder wings above without spots, and the anal angle beneath yellow.
" Smaller [than 0. Priamus]. Expansion of the wings six inches. Anterior wings; brown spot
under the median vein longer, beginning at the fourth branch. Median vein bordered with green
Ihe posterior wings have no black spots on the green patch. Underneath the anterior wings have the
