named Scolypopites bryan, n.g. et sp., the generic name 
indicating its close affinity to the recent Australian genus 
Scolypopa, the common passion-vine hopper of Eastern 
Australia, to which it is prebably directly ancestral, and the 
specific name being a dedication to its discoverer. Prof. 
Richards, Mr. Tryon, Prof. Goddard, Dr. A. J. Turner, and 
Mr. Bryan took part in the discussion on the paper and 
Mr. Dunstan’s exhibits. 
Mr. G. H. Hardy read a paper by Prof. T. H. Johnston 
and himself, entitled ‘‘Observations Regarding the Life 
Cyvyele of Certain Australian Blowflies,’’ and gave an account 
of some of the work he was engaged upon as a Walter and 
Kliza Hall Fellow. The work of the Fellowship consisted 
chiefly of experimental investigation of the biology of blow- 
flies. It had been discovered that a batch of these flies bred 
under uniform conditions varied greatly in the period of 
the life cycle, particularly in the prepupal stage, and it was 
pointed out that chaleid wasps with suitable habits in other 
parts of the world might be introduced into Australia to 
supplement those already preying upon the sheep maggot 
flies here.
