ZOOLOGICAL GEOGRAPHY.

genera, two of which are peculiar ( Odontria and Stethaspis ) ; and 
two Australian (Pericojrtus and Calonota). There are no 
Cetoniid*. 
There is only one Buprestid, belonging to the Australian genus 
Cisseis. The Elaterida3, (about a dozen species,) belong mostly 
to Australian genera, but two, Mdablax and Ocliostermis , are 
peculiar. 
There are 30 species of Curculionidae, 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 Carabidae, 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 
Coccinclla. 
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. Menicops occurs elsewhere only in Tasmania 
and Chili. Cryptops, only in the north temperate zone ; while 
two others, Cermatia and Cormocephalus , both occur in 
Australia.
