382 LIFE STORIES OF AUSTRALIAN INSECTS. 



Many popular names are given to the cicadas — 

 '* green monday," ''yellow monday," ''double 

 drummers," "millers," etc. 



Some of the commoner species are of genus 

 Cyclochila; C. australiasiae is the "green monday." 



The "double-drummer" is Thapha saccata, with 

 bag-like drums at the side of the body. 



The "floury baker" or "miller" is smaller, and 

 is a great prize to children, being more uncommon 

 than the "yellow and green mondays. " 



Small cicadas are very numerous in the western 

 districts of New South Wales. 



During the summer of 1919, the number of cicadas 

 was abnormal in their abundance; many residents 

 of Killara and other suburbs had their nights' rest 

 disturbed by the song of these insects, which was 

 continued all through the bright moonlight nights.
