There is also in the “ Iluddersfield iSTaturalist,” for 1864 — 5, a 
list of over seven hundred species, by Mr. T. E. Gunn, of Norwich, 
recorded as having been taken in Norfolk, and I wish to acknoAV- 
ledge my obligation to Mr. Gunn for the ready and obliging 
manner in winch he has assisted me Avith information as to 
the sources from Avhich his list AA^as compiled, and the localities, 
as far as knoAvn, in Avhich the species Avere taken, and as I am 
satisfied that he Avas grossly and intentionally deceived by an 
interested collector as to the occurrence of at least one hundred 
and fifty species in the county, I have preferred to ignore 
this list, and substitute for it such information as he Avas able to 
substantiate. 
As it is necessary in a list of this kind to have some definite 
boundary, I bave felt compelled to omit a few species which are 
knoAvn to occur at Brandon, and other places on the borders 
of the county, AAdien they have not actually been taken Avitbin its 
limits. 
The arrangement Avhich I have folloAved is that of M. Guenee, 
as published in Mr. Henry Doubleday’s “ Synonymic List of 
British Lepidoptera,” and in many cases in AA'hich corrections or 
alterations in nomenclature have been made, I have appended the 
synonym in brackets to assist identification. 
Several species Avhich have been recorded erroneously in the 
county are also placed in brackets to distinguish them from those 
truly forming a part of the list.
