and Australia; and the Australian genera, Adelotopus, Silpho- 
morpha, and Sphallomorpha, form with it a distinct. tribe of Cole- 
optera. These being all confined to the warmer regions, and having 
so scattered a distribution, are no doubt the relics of a wide- 
spread group. The Australian genus, Promecoderus, has, how- 
ever, closely allied genera (Cascelius and its allies), in Chili and 
Patagonia; while two small genera confined to the Auckland 
Islands (Heterodactylus and Pristancyclus) are allied to a group 
found only in Terra-del-Fuego and the Falkland Islands, 
(Migadops) ; and in these cases we may well believe that a direct 
transmission has taken place by some of the various means 
already indicated. ° 
In Lucanide, Australia is only moderately rich, having 7 
peculiar genera. The most important are Ceratognathus and Rhys- 
sonotus, confined to Australia; Lzssotes to Australia and New 
Zealand; Lamprima to Australia and Papua. Mitophyllus and 
Dendroblaz inhabit New Zealand only ; while Syndesus is found 
in Australia, New Caledonia, and tropical South America, 
The beautiful Cetoniide are poorly represented, there being 
only 3 peculiar genera ;—Schizorhina, mainly Australian, but 
extending to Papua and the Moluccas ; Anacamptorhina, con- 
fined to New Guinea, and Sternoplus to Celebes, Lomaptera is 
very characteristic of the Austro-Malay Islands. This almost 
tropical family shows no approximations between the Australian 
and Neotropical faunas. 
In Buprestide, the Australian region is the richest, possessing 
no less than 47 genera, of which 20 are peculiar to it. Of these, 15 
are peculiar to Australia itself, the most important being Stig- 
modera (212 species), thon (13 species), and Nascio (3 species) ; 
Cisseis (17 species), and the magnificent Calodema (3 species), 
are common to Australia and Austro-Malaya; while Sambus 
(10 species) and Anthaxomorpha (4 species), with some smaller 
groups, are peculiarly Austro-Malayan. In this family occur 
several points of contact with the Neotropical region. Stegmo- 
dera is said to have a species in Chili, while there are undoubt- 
edly several allied genera in Chili and South Temperate America. 
The genus Curis has 5 Australian and 3 Chilian species, and
