and Australia ; and the Australian genera, Adclotopus, Sil^'ilio- 

 rnorjyha, and Sj^haUomorpha, 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, Promccoderus, has, how- 

 ever, closely allied genera (Cascelius and its allies), in Chili and 

 Patagonia; while two small genera confined to the Auckland 

 Islands {Hetcrodactylus and Pristancyclus) ai'e 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 Lucanidse, Australia is only moderately rich, having 7 

 peculiar genera. The most important are Ccro.tognathus and lihys- 

 sonotus, confined to Australia ; Lissotes to Australia and New 

 Zealand; Lamp)rima to Australia and Papua. MitopUylliis ?a\d 

 DendroUax inhabit New Zealand only ; wdiile Syndcsus is foand 

 in Australia, New Caledonia, and tropical South America. 



The beautiful Cetoniidte are poorly represented, there being 

 only 3 peculiar genera ; — SchizorJmia, maiidy Australian, but 

 extending to Papua and the Moluccas ; Anacamptorhina, con- 

 fined to New Guinea, and Stcroiophts 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 Buprestidffi, 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 in.iportant being Stig- 

 modera (212 species), Etlion (13 species), and Nascio (3 species) ; 

 Cisscis (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. Stigmo- 

 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
