Volume Ii Part 15 (2/2)

Pap. (Tro. dent.) Wings dentated, black; posterior above with a five-cleft, violet-crimson spot; anterior beneath with a transverse, central, whitish band.

P. Evander. _G.o.dart, En. Meth._ _vol._ ix. _p._ 32. _no._ 18.

Both s.e.xes of this newly described insect are here, for the first time, figured; that above is of the male, and beneath is represented the under side of the female. The crimson spots (which finely relieve the brownish velvet-like black on the upper surface of the wings) are, in some lights, most beautifully glossed with changeable violet, and appear either darker or paler according to the position in which the insect is viewed.

Southern Brazil is, undoubtedly, more rich in this splendid family than the northern provinces of that vast country. I never saw this species except in Rio Janeiro, where it is common: nor do I know of any other, belonging to the division of _Trojani_, which have the lower wings sharply dentated, and with an appearance of obsolete _acute_ tails; a character more developed in the female of this species than in the male.

SPECIFIC CHARACTER.

_P. (Troj. orb.) Alis immaculatis fuscis, inferis...o...b..culatis, ecaudatis; fronte, striga laterali subthoracica anoque rubris._

P. (Troj. orb.) Wings immaculate, brown; lower orbicular, not tailed; front, lateral stripe on the thorax beneath, and tip of the body red.

The colours of this insect are unusually sombre, and present a striking contrast to the gaudy tints by which the majority of these gay creatures are ornamented; it is so far remarkable, but it is more interesting to the entomologist, as being an unpublished addition to this genus. It was discovered in Java by Dr. Horsfield; and the drawing was made from an unique specimen which I observed while engaged in a long and laborious arrangement of the Linnaean _Papilionidae_, (as they now appear at the India House,) collected by that zealous naturalist for the India Company.

Between the nerves of the anterior wings (which are remarkably large) are parallel central stripes, of a darker brown; a character common to many Indian species, but not found, I believe, in any of those from the New World.
