Page 56. In the table Identifications of Lepidoptera, the middle column is a relic 

 from a set of calculations of the percentages of identifications among 

 all insects. The appended figures are to be substituted as represent- 

 ing the percentages of identifications among all Lepidoptera. In 

 explanation of the third column in this table, it may be said that it 

 differs from others given further on in the work by omission of 

 figures for families not represented among the food identifications.
