The Insect remains about to be described are derived from three sources. 
'I'he N. S. Wales specimens, with the exception of one species, were collected 
by Mr. C. S. MTlkinson, P.G.S., &c., the Geological Surveyor-in-Charge, and 
by Mr. T. W. Edgeworth David, B.A., Geological Surveyor, during the latter’s 
survey of the Vegetable Creek Tin-field, and are of Tertiary age. The single 
specimen was obtained by Mr. Charles Cullen, Collector to the Geological 
Survey, from the Mesozoic beds of the Talbragar Eiver. The Insect remains 
from Queensland were kindly lent to us by Mr. T. H. Simmonds, of Brisbane. 
The fragmentary nature of the remains and their film-like appearance 
liave rendered determination difficult, but the identifications we have ventured 
to make are probably but little removed from accuracy. 
The Systematic Descriptions are preceded by an Introduction, in which 
tlie, so far, brief history of Australian Eossil Insects is placed before the 
reader.
