This Papilio, and that in the following plate, have given us more trouble than any other
infedt in the work. Unfortunately the Linnasan Cabinet poffeffes neither; and the fpecific
charadters and defcriptions in the publications of our great mailer, as well as thofe of his
worthy difciple Fabricius, are by no means fufficient to remove all doubt. In the prefentcafe,
however, the Bankfian Mufeum, revifed by Fabricius, with the fynonyms of Drury and Cramer,
enable us with tolerable confidence, to offer this infedt as the Papilio Troilus, nothing con-
tradidtory occurring in the two principal fyftematic authors above mentioned. We beg leave
only to remark, that P. Afterias, Fair. p. 6, feems not to be different from this. Our upper-
moft figure is precifely the No. 2. of Drury; and, according to his opinion, and the obferva-
tions of Mr. Abbot, is only a variety (perhaps a fexual difference) of the other. Drury’s
No. 4, being the under fide of No. 1, his Aftinous, has nothing to do with either.
The black dot in the orange fpot of the anal angle feems a mark of P. Troilus. Its caterpillar
is very near that of P. Machaon, and betrays the im^erfedtion o f our prefent fyftematic
arrangements of this tribe, with refpedt to natural affinities.
P. Xuthus, Linn. Syfi. Nat. 751, is next akin to Troilus; and when Linnams fays it is
t(Jimillimus P. Ajaci," we rather believe he compared it with Troilus, which is the Ajax of
Clerck, though widely different from his own reprefented in our Tab. 4.
