chap, xin.] THE AUSTRALIAN REGION. 457 



Chatham Islands to South America — has already been noticed \ 

 while another species, G. fasciatus, is found in the Chatham and 

 Auckland Isles as well as New Zealand. A second genus 

 peculiar to New Zealand, Neochanna, allied to Galaxias, has 

 recently been described. Prototroctes oxyrhynchus is allied to an 

 Australian 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 in 

 New Zealand ! while the genus Agonostoma ranges to Australia, 

 Celebes, Mauritius, and Central America. 



Insects. — The great poverty of this class is well shown by the 

 fact, that only eleven species of butterflies are known to inhabit 

 New Zealand. Of these, six are peculiar, and one, Argyrophenga 

 (Satyridse), is a peculiar genus allied to the Northern genus 

 Erebia. The rest are either of wide range, as Pyrameis cardui 

 and Diadema bolina ; or Australian, as Hamdyaas zoilus ; while 

 one, 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 Sphin- 

 gina except the British currant-moth, JEgeria tipuliformis, 

 doubtless imported. Coleoptera are better represented, nearly 

 300 species having been described, all or nearly all being pecu- 

 liar. These belong to about 150 genera, of which more than 50 

 are peculiar. No less than 14 peculiar genera belong to the 

 Carabidse, mostly consisting of one or two species, but Demetrida 

 has 3, and Metaglymma 8 species. Other important genera are 

 Dicrochile, Homalosoma, Mecodema, and Scopodes, all in common 

 with Australia. Mecodema and Metaglymma are the largest 

 genera. Even the Auckland Islands have two small genera 

 of Carabidse found nowhere else. 



Cicindelidse are represented in New Zealand by 6 species of 

 Cicindela, and 1 of Dystiysidera, a genus peculiar to the Austra- 

 lian region. 



The Lucanidse are represented by two peculiar genera, Den- 

 drdblax and Oxyomus ; two Australian genera, Lissotes and 

 Ceratognathus ; and by the almost cosmopolite Dorcus. 



The Scarabeidse consist of ten species only, belonging to four
