CHAP. XuI.] 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 (Haplochitonide) 
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 
(Satyride), is a peculiar genus allied to the Northern genus 
Erebia. The rest are either of wide range, as Pyrameis card 
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, Myeria 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 
Carabide, 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 Carabide found nowhere else. 
Cicindelide are represented in New Zealand by 6 species of 
Cicindela, and 1 of Dystipsidera, a genus peculiar to the Austra- 
lian region. 
The Lucanide are represented by two peculiar genera, Den- 
droblax and Oxyomus; two Australian genera, Lissotes and 
Ceratognathus ; and by the almost cosmopolite Dorcus. 
The Scarabeide consist of ten species only, belonging to four
