Explanation of Table 1. 



The figures in Table I. refer to the '^ provinces" pre- 

 viously explained on p. 417 ; the numbers opposite the 

 name of each species indicating- the provinces in which 

 the occurrence of that species is reported on trustworthy 

 evidence. 



A blank space, or the substitution of a small horizontal 

 mark ( - ) instead of a figure, indicates that no evidence 

 has been found of the occurrence of the species in the 

 corresponding province . 



The substitution of the letter " o " indicates that the 

 occurrence is doubtful, or that the evidence requires 

 confirmation. 



An asterisk affixed to the number of any province 

 denotes that there is only one authority for the occurrence 

 of the species under consideration in such province ; but 

 the number of observers in Ireland being very small, this 

 mark has not been employed in provinces 19, 20, 21, 22. 



In this and the following Tables, records at second 

 hand have been admitted with caution, and no records 

 of the capture of larvas only, where the perfect insect has 

 not been bred, have been considered satisfactory. 



Where species are recorded as occurring at some town 

 on the borders of a county or province without an exact 

 locality being given, the doubtfully-placed localities are 

 assumed to be within the same county or division as the 

 town itself.
