308 THE RIVER-SIDE NATURALIST. 



The Odocantha Melanusa, with its blue head and thorax 

 and testaceous elytra, inhabiting reeds and marshy ground, 

 would be almost the natural simile to the Macaw Tag. 



Many others might be enumerated ; but sufficient have 

 been given to show that the smaller beetles found in the 

 vicinity of rivers must often become food for fish. 



The reader is referred to the coloured representations 

 of the above in Curtis's " Coleoptera " and Spry and 

 Schuckard's " British Coleoptera."
