breeze, would be very apt to be blown out to sea. The most 
remarkable instance I ever knew of an insect being caught far from 
the land, was that of a large grasshopper (Acrydium), which flew on 
board, when the Beagle was to windward of the Cape de Yerd 
Islands, and when the nearest point of land, not directly opposed 
to the trade wind, was Cape Blanco, on the west of Africa, 370 
miles distant.* ”—(Darwin’s Journal, pp. 185,186.) 
Papilio Pelaus (Plate 16, fig. 1, 2).—Figures of this species, 
doubtless derived from Drury’s specimen described by Fabricius, 
are contained in Jones’s Series of Drawings (vol. 1, pi. 32), so 
often referred to by that author. They agree with my figures 
except that the upper surface of the wings is darker (blacker) 
in Jones’s drawings—the evident result of his figure hav¬ 
ing been made from a recent specimen and mine from an old one. 
The minute anterior whitish, transverse striga near the extremity 
of the abdomen in the anal area of the hind wings, is also not 
represented in Jones’s drawing. It is not improbable that 
Mr. Doubleday’s specimen, from which my figures were drawn, may 
be the original insect described by Fabricius, from Drury’s specimen, 
which was, I believe, purchased at the sale of his collection by the 
late Mr. Haworth. 
Cetonia Iris, Fabricius, Ent. Syst. 2, 144. Oliv. 1, 6, tab. 8, 
f. 77 — Deceived by the locality of Surinam given by Fabricius to 
this species (the typical specimen of which is still contained in the 
Banksian Collection at the Linnean Society), and knowing that no 
Gnathocerm of Gory and Perclieron (Coryphe, MacL.), nor indeed 
any insect closely allied thereto, inhabit the New Y orld, I did not 
think of comparing the Gnathocera amabilis, Bainb. (Tmesoi- 
rhina a. Westw. ante, p. 71), with the Banksian insect. My fiiend 
Burmeister having however suggested to me, by letter, the possi¬ 
bility that the two supposed species were identical, I have compai ed 
them together, and find that Mr. Hope s specimen differs only fiom 
the Banksian one in such characters as are sexual, the latter being 
a female with tridentate anterior tibise. The name Iris, Fab., must, 
therefore, be substituted for that of amabilis, Bainbr. Di. Scliaum 
has united Iris with Schizorliina cyanea, G. and P.; Sell. Swartzn,
