discussed in a recent paper in the Transactions of the Entomo- 

 logical Society of London. I have included with the Australian 

 species all the material known to me from the Australasian region, 

 i.e., New Guinea and the adjoining islands, and the islands of 

 the South Pacific (excluding New Zealand); and have therefore 

 altered the title of this series of papers from Australian to 

 Australasian.
