(Trojani orbiculares) alis atris; superis fascia breviori (foeminae alba) antice alba, postice cyanea, inferis dentatis, macula coccinea quadripartita._ Papilio (T. orb.) wings black, superior, with a short white band, which is blue at the base (in the female entirely white); inferior dentated, with a four cleft crimson spot. Papilio Polymetus. _Godart in Ency. Meth._ vol. ix. p. 35. _no._ 28. * * * * * First described by M. Godart; unless, indeed, it may hereafter prove a variety of _P. Lycander_ (Cramer, Pl. 29. C. D.) which approaches as near to the male, as _P. Hippason_ does to the female. The first sex is here represented at the upper and under figures; the middle is of the female, which M. Godart has not described. It is a native of Brazil; I found it at Bahia only in certain woods, and subsequently met with a variety in the province of Rio Janeiro, differing only in being much larger. * * * * * Pl. 93 [Illustration] PAPILIO Pandrosus. * * * * * SPECIFIC CHARACTER. _P.

Godart has anticipated me in the first publication of this, and a great many other newly discovered Brazilian insects; it has, however, not been figured; and I take this opportunity of expressing my doubts, whether this and the next are not sexes of the same species, rather than two, permanently distinct. I have not, at this particular time, the means of referring either to my notes or my collections, by which the recollection I have on the subject might be in some way confirmed; and, until this is done, it is much better retaining the two insects as distinct species: the figures of both will show their very close resemblance, in every thing but the bands on the upper surface of the wings. I found them common in the province of Rio de Janeiro. * * * * * Pl. 94 [Illustration] PAPILIO Torquatus. * * * * * SPECIFIC CHARACTER. _P. (G.
