In Van Diemen's Land, However, I Found Four Species Of
Onthophagus, Two Of Aphodius, And One Of A Third Genus, Very
Abundantly Under The Dung Of Cows; Yet These Latter Animals Had
Been Then Introduced Only Thirty-Three Years.
Previous to that
time the kangaroo and some other small animals were the only
quadrupeds; and their dung is of a very different quality from
that of their successors introduced by man.
In England the
greater number of stercovorous beetles are confined in their
appetites; that is, they do not depend indifferently on any
quadruped for the means of subsistence. The change, therefore,
in habits which must have taken place in Van Diemen's Land is
highly remarkable. I am indebted to the Rev. F. W. Hope, who, I
hope, will permit me to call him my master in Entomology, for
giving me the names of the foregoing insects.
