genera, two of which are peculiar (Odontria and Stethaspis) ; and 

 two Australian (Pericoptus and Calonota). There are no 

 Cetoniidse. 



There is only one Buprestid, belonging to the Australian genus 

 Cisseis. The Elateridae, (about a dozen species,) belong mostly 

 to Australian genera, but two, Metablax and Ochosternus, are 

 peculiar. 



There are 30 species of Curculionidse, belonging to 22 genera. 

 Of the genera, 12 are peculiar ; 1 is common to New Zealand 

 and New Caledonia ; 5 belong to the Australian region, and the 

 rest are widely distributed. 



Longicorns are, next to Carabidse, the most numerous family, 

 there being, according to Mr. Bates (Ann. Nat. Hist., 1874), about 

 35 genera, of which 26 are peculiar or highly characteristic, 

 and 7 of the others Australian. The largest and most character- 

 istic genera are JEmona and Xyloteles, both being peculiar to 

 New Zealand ; few of the remainder having more than one or 

 two species. Demonax extends to the Moluccas and S. E. 

 Asia. A dozen of the genera have no near relations with those 

 of any other country. 



Phytophaga are remarkably scarce, only two species of 

 Colaspis being recorded ; and there is only a single species of 

 Coccinella. 



The other orders of Insects appear to be equally deficient. 

 Hymenoptera are veiy poorly represented, only a score of species 

 being yet known ; but two of the genera are peculiar, as are all 

 the species. The Neuroptera and Heteroptera are also very 

 scarce, and several of the species are wide-spread forms of the 

 Australian region. The few species of Homoptera are all 

 peculiar. The Myriapoda afford some interesting facts. There 

 are nine or ten species, all peculiar. One genus, Lithobius, 

 ranges over the northern hemisphere as far south as Singapore, 

 and probably through the Malay Archipelago, but is not found 

 in Australia. Henicops occurs elsewhere only in Tasmania 

 and Chili. Cryptops, only in the north temperate zone ; while 

 two others, Cermatia and Cormocephalus, both occur in 

 Australia.
