iv Preface. 
Canal and the consequent direct and rapid communication 
between the Yellow Fever districts and the East and our 
Australian Colonies, it is most essential that all possible infor- 
mation be collected regarding the genus Stegomyia and its 
distribution. 
I shall still be glad to receive further collections and notes, and 
also suggestions regarding this and the preceding volumes.
