in species. Pascoe calculates their numbers at ‘200,000. Of 
the four classes into which, the Sub-kingdom is divided, the 
Insecta are very much the most numerous, and the position 
they occupy in the Australian Fauna will be best ascertained 
by taking the different Orders im succession. 
Though all or nearly all of the most important Families of 
the various Orders are well represented, yet the genera are as 
a rule so distinct from those of other parts of the world, that 
anyone having the slightest acquaintance with Entomology 
would at a mere glance recognise an Australian collection. 
The Order COLEOPTERA is the most numerous and best 
worked out in Australia of all the Orders of Insecta. The 
numbers of this Order for the whole world are estimated at 
80,000, and of these quite 10,000 may be quoted for Australia, 
and it is probable that in a few years’ time thousands may be 
added to that estimate. 
The CicINDELID® are not very numerous, and the most 
noticeable feature about them is the appearance of the African 
genus Megacephala and the South American genus Tetracha.. 
The Family of the CARABIDE is a very large one, and presents 
“marked peculiarities. The true CaraBipm, containing the 
genera Carabus, Tefflus, Cychrus, Leistus, Nebria, Hlophrus, 
Omophron, &c., are entirely unrepresented, except by two species 
of Calosoma and the Australian genus Pamborus. 
The TRUNCATIPENNES are also very numerous, but they 
differ very much from the Truncatipennes of other countries. 
A numerous group, the Helluwonide, are almost exclusively 
Australian, as are also the genera Xanthophlea, Homothes, 
Sarathrocrepis, Philophlens, Agonochila, Cataseopus, Sco- 
podes, Silphomorpha, and Adelotopus. 
The Morro group is fairly numerous, and includes the 
largest known Carabideous insect ( Campylaenemis Schreetten. ) 
The Brparvivi are numerously represented in Australia by a 
section of the Sub-Family of ScarrriDA@, originally all con- 
tained in the Fabrician genus Carenum. It is now divided 
into ten genera, and comprises over 200 species. The 
Frronip#@ and Harpatip# are also numerous, but are, with 
a few exceptions, very like insects of the same families else- 
where. The BEmMBIDIIDs# seem to be few, but is not unlikely 
that their small size may have caused them to escape the notice 
of collectors. The Families DytTiscipm and GyrRINID# are 
not numerously represented, and exhibit no _ peculiar 
characteristics. 
The Pa.Picornia are few in species, but all the families are 
represented. 
_ The STaPHYLINID# are remarkably few in number; the 
PsELAPHIDa seem to be abundant. ‘The Clavicorn Beetles 
are not very numerous, but most of the families have their 
%
