The present paper is not designed to be a complete monograph of the 

 Australian yEschnince, on the lines of E. M. "Walker's excellent work on 

 the genus u^sclma in North America *. To deal with the whole subfamily 

 in Australia on such lines would not only have involved the production of 

 a paper far beyond the bounds of the present one in cost and size, but would 

 have unnecessarily duplicated much good work already accomplished. Most 

 of the Australian species have been already well described by Rene Martin f, 

 while a few have been added by Forster and myself. But so far nothing- 

 has been published on their life-histories, nor has any attempt been made to 

 survey their geographical distribution and their phylogeny (except in so far 

 as the Australian forms have entered into the gene7'al discussion of these 

 problems for the whole subfamily). It has been mainly with these three 

 objects in view that I have been collecting material for the present paper
