Australia and Africa. The Indo-Chinese sub-region is the head 

 quarters of the family, whence it diminishes rapidly in all

 of opinion. The distribution of the genera here admitted is as 

 follows ; and as the genera are widely scattered in the Hand 

 List, reference numbers are prefixed in every case.
