In the following tables, the elements of the food, arranged in 

 systematic order, are placed at the left of each page, while a ver- 

 tical column of the table is assigned to each genus of beetle. 

 The upper figure of each couple indicates the number of speci- 

 mens in whicli the given element was found, while the lower fig- 

 ures (decimal) show the ratio of the element to the entire food of 

 of all the examples of the genus. The dagger has been used 

 to indicate a trace too small to figure in the percentages, 

 usually less than one-half per cent., and an asterisk 

 denotes that the element against which it is placed was present in 

 the food, but that the ratio was not estimated.
