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 which 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.
