Introduction. 



The present paper deals with a portion of the ver}' interesting 

 fossil insects recently obtained from the Ipswich Beds b)' Mr. B. 

 Dunstan, Chief Government Geologist of Queensland, to whom 

 I am much indebted for the opportunity of studying such fine 

 and, in many respects, unique material. This collection may be 

 looked upon as the third collection of insect fossils made at 

 Ipswich. The first, or Simmonds Collection, was made in 1890 

 by Mr. T. H. Simmonds, of Brisbane, and the specimens were 

 described by Etheridge and Olliff in the same year.* In 1909, 

 Mr. Dunstan made a second collection of insects from the same 

 locality. These were sent to me for study in 1913, together 

 with some fossil insects from other beds in Queensland and New 

 South Wales. All these were dealt with in a paper published 

 last year by the Queensland Geological Survey. f In this paper,
