ZOOLOGICAL GEOGRAPHY.

and Australia ; and the Australian genera, Adelotopus, Sityho- 
morpha , and Sphcdlomorpha, 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 Pristaiicyclus) 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 Lucanidae, Australia is only moderately rich, having 7 
peculiar genera. The most important are Gercitognathus and Iihys- 
sonotus , confined to Australia ; Lissotes to Australia and Hew 
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 Cetoniidae 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. LomapUra is 
very characteristic of the Austro-Malay Islands. This almost 
tropical family shows no approximations between the Australian 
and Neotropical faunas. 
In Buprestidse, 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 Nciscio (3 species) ; 
Cisseis (17 species), and the magnificent Calodema (3 species), 
are common to Australia and Austro-Malaya ; while S 'ambus 
(10 species) and A nthaxomorpha (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
