chap, xin.] THE AUSTRALIAN REGION. 457Chatham Islands to South America—has already been noticed \while another species,G. fasciatus, is found in the Chatham andAuckland Isles as well as New Zealand. A second genuspeculiar to New Zealand, Neochanna, allied to Galaxias, hasrecently been described. Prototroctes oxyrhynchus is allied to anAustralian species, but belongs to a family (Haplochitonidse)which is otherwise South American. An eel, Anguilla latirostris,is found in Europe, China, and the West Indies, as well as inNew Zealand ! while the genus Agonostoma ranges to Australia,Celebes, Mauritius, and Central America.Insects.—The great poverty of this class iswell shown by thefact, that only eleven species of butterflies are known to inhabitNew Zealand. Of these, six are peculiar, and one, Argyrophenga(Satyridse), is a peculiar genus allied to the Northern genusErebia. The rest are either of wide range, as Pyrameis carduiand Diadema bolina ; or Australian, as Hamdyaas zoilus ;whileone, Danais erippus, is American, but has also occurred in Australia,and is no doubt a recent introduction into both countries.Only one Sphinx is recorded, and no other species of the Sphinginaexcept the British currant-moth, JEgeria tipuliformis,doubtless imported. Coleoptera are better represented, nearly300 species having been described, all or nearly all being peculiar.These belong to about 150 genera, of which more than 50are peculiar. No less than 14 peculiar genera belong to theCarabidse,mostly consisting of one or two species, but Demetridahas 3, and Metaglymma 8 species. Other important genera areDicrochile, Homalosoma, Mecodema, and Scopodes, all in commonwith Australia. Mecodema and Metaglymma are the largestgenera. Even the Auckland Islands have two small generaof Carabidse found nowhere else.Cicindelidse are represented in New Zealand by 6 species ofCicindela, and 1 of Dystiysidera, a genus peculiar to the Australianregion.The Lucanidse are represented by two peculiar genera, Dendrdblaxand Oxyomus ; two Australian genera, Lissotes andCeratognathus ;and by the almost cosmopolite Dorcus.The Scarabeidse consist of ten species only, belonging to fourVol. I.—31
