The figures and descriptions of Guerin, though fewer in number, are more detailed than those of Dr. Boisduval, who was much limited for space.

It would take up too much time to give a tithe of the names of the entomologists who have described New Holland insects* as nearly every working student of insects abroad and at home has added to the list.

(Footnote.  The entomologist who would attempt to do this must give a Universal Entomological Bibliography, as scarcely a Journal or volume of Transactions of any Scientific Society appears without containing fewer or more species from the great Australasian Continent and its islands.)

Messieurs Audouin, Blanchard, and Boisduval will shortly publish descriptions of the insects etc. collected on D’Urville’s last voyage.  Latreille, Dejean, Schoenherr, and Klug must be specially particularized; Gory, Percheron, Chevrolat, Aube, Serville, Reiche, Spinola, Fischer, and Mannerheim have all more or less added to our acquaintance with the species.  Many New Holland Arachnida and Pacific Ocean Crustacea have been described in the well-known works of the Baron Walckenaer and Dr. Milne Edwards.  In this country Kirby, Hope, Curtis, G.R.  Gray, Waterhouse, Shuckard, Newman, and Westwood have been the principal scientific men who have attended to species of annulosa.  Bennett, Mr. Surgeon Hunter, Darwin and Major Mitchell, when opportunities offered, collected many species and neglected not the subject of their habits; the last-mentioned having also described (specifically) one or two species in his interesting work.  Macleay’s Appendix to Captain King’s voyage* is universally known.

(Footnote.  King (Captain Philip P., R.N., F.R.S. etc.) Narrative of a Survey of the Intertropical and Western Coasts of Australia performed between the years 1818 and 1822 2 volumes London 1827.  Appendix Catalogue of Insects collected by Captain King, R.N., 192 species of Annulosa, 188 Insects, 4 Arachnida pages 438 to 469; “eighty-one of the species are new.”  In this paper Macleay institutes a Curculionidous genus near Phalidura, which he names Hybauchenia, the type being H. nodulosa.  Carpophagus type C. Banksiae “would probably with Linnaeus have been a Bruchus.”  Megamerus “has an affinity to Sagra, but differs from that genus in having setiform antennae, porrect mandibles, and securiform palpi, its habit is also totally different, and more like that of some of those insects which belong to the heterogeneous magazine called Prionus; it is undoubtedly the most singular and novel form in Captain King’s collection.”  Type M. kingii.)
