PORTLAND LEPIDOPTERA. ol 



Iii the following list I have as a rule given the authority when 

 only one or two specimens of a species have been recorded or when 

 the occurrence of the species has been noted by only one person, 

 and I have not myself met with it. When I considered it desir- 

 able, on account of any doubt which may have been cast on the 

 record or for any other reason, to mention the authority, I have 

 indicated it by initials in brackets as follows : 



(E. K. B.) for Eustace R. Bankes. 



(0. P. C.) 0. P. Cambridge. 



(C. R. D.) Charles R. Digby 



(C. W. D.) C. W. Dale 



(C. P.) Charles Partridge 



(J. G. R.) ,, J. G. Ross (entered on the authority of Mr. C. 

 W. Dale). 



(N. M. R.) N. M. Richardson. 



(J. J. W.) ,, J. J. Walker. 



My friends, Rev. 0. P. Cambridge, Rev. C. R. Digby, Messrs. 

 Bankes and Dale, and Colonel Partridge, I have already referred 

 to. My late friend Mr. J. G. Ross, who died some years ago, at 

 one time did a good deal of collecting among the Portland Macro- 

 iepidoptera, and the names of several species which have been 

 captured by him alone have been communicated to me by 

 Mr. C. W. Dale. Mr. J. J. Walker, R.JST., has also collected at 

 Portland, and for most of his records in the following pages I 

 have to thank Mr. E. R. Bankes. 



I have only to add that the arrangement and names in South's 

 " Entomologist " List of British Lepidoptera (which has been 

 used in the Dorset County Museum cabinets) have been followed 

 in the appended list. 



The abbreviations of authors' names used are the same as in 

 South's List, above mentioned.
