The specimens described above were bred out by Mr. F. J\ 

 Spry from larvae obtained at Nyora, Victoria, by Mr. J. Searle, 

 and presented to the National Museum, Melbourne, where the 

 types will be found. 



I am indebted to Mr. Edwards of the British Museum for 

 •specimens of C. culiciformis, de Geer, the European species, for 

 comparison. From this C. australiensis differs widely in its 

 smaller size, its darker colour, and its clothing, the European 

 species being clothed with long conspicuous golden hairs, and hav- 

 ing the wings much more hairy. 



C. cinctipcs, the American species differs inter alia malt a in the 

 banded legs. 



A specimen in the British Museum collection labelled C. lap- 

 ponicus, Bergroth, is a much larger and otherwise different species.
