Curtis and Haliday have published and are engaged in publishing the description of Annulosa collected by Captain King, while those collected by Mr. Darwin on the voyage of the Beagle have been entrusted to Mr. Waterhouse, who has published descriptions of some in the Entomological Society's Transactions and in the Annals of Natural History. Hope's papers in the Zoological Transactions and the Coleopterist's Manual are well known, as are Mr. Newman's in different Magazines and Annals. We rejoice to see in a late number of a small periodical sheet exclusively devoted to Entomology* and edited by this gentleman a letter from Mr. Davis, containing some interesting information regarding the insects of Adelaide; and in the same periodical there are many New Holland insects described. Much may be expected from Messrs. Macleay and Swainson, both at present in the South Sea islands, and it is to be hoped that in a short time the fruits of their researches will be before the public. Mr. Gould collected many insects on his Ornithological expedition to New Holland, descriptions of which, from the pen of the Reverend F.W. Hope, may shortly be looked for. (*Footnote. The Entomologist, conducted by Edward Newman. London Van Voorst in Monthly Numbers.) The north-west coast of New Holland has been but little investigated, and yet in that quarter the late Allan Cunningham gathered a rich harvest of rare and unknown species; but it would take too much space to tell what parts have not been searched for insects, suffice it to say that the Swan River settlement, Kangaroo and Melville islands, Adelaide, Sydney, and Hobart Town seem all peculiarly rich in species, and what may we not expect from New Zealand, from the samples already given of its entomology by Fabricius and Shuckard, not to mention others who have described species from that locality. We yet hope to see a general work on the subject similar to the truly national work on the Birds and Kangaroos at present publishing by Mr. Gould. Mr. G.R. Gray commenced such a work in quarto, and the beautiful number illustrated by the late Charles Curtis, containing species of Phasmidae, it is to be hoped will not be left single.* I have only room to add that, owing to many other occupations, I can at present give only a very imperfect list of the species you have presented to the National Museum, which were all collected by you on the shores of King George's Sound. A.W. (*Footnote. I see in Laporte and Gory's Histoire Naturelle et Iconographic des Coleopteres, a work on Australian Insects, by the Reverend Frederick W. Hope, often quoted as Synopsis of the Insects of New Holland, but this must be privately printed, as I have never seen it or heard of it elsewhere. ... COLEOPTERA. CARENUM, Bon. Carenum perplexum.
