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, Promecodertcs, has, how- 

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

 Patagonia; while two small genera confined to the Auckland 

 Islands (Hctcrodactylus and Pristancyclus) are allied to a group 

 found only in Terra- del-Fu ego 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 Ceratognathus and Rhys- 

 sonotus, confined to Australia ; Lissotes to Australia and New 

 Zealand ; Lamprima to Australia and Papua. Mitophyllus and 

 Dendroblax inhabit New Zealand only ; while Syndesus is found 

 in Australia, New Caledonia, and tropical South America. 



The beautiful Cetoniidse are poorly represented, there being 

 only 3 peculiar genera ; — Schizorhina, mainly Australian, but 

 extending to Papua and the Moluccas ; A nacamptorhina, 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 Buprestidae, 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), Ethon (13 species), and Kascio (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. 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 Cutis has 5 Australian and 3 Chilian species, and
