THE FAUNA OF THE LONDON DISTRICT. 
LEPIDOPTERA. 
Compiled by Dn. F. .1. IIUCKELL, lidited, with the additions subsequent to 
LS'hJ, by LOUIS 15. PHOUT, F.E.S. 
The compilation of the present Fiiuna Lists, under the auspices of 
the City of London Entomological and Natural History Society is tho 
outcome of a paper read before the Society by Dr. E.' J. Buckell, on 
‘‘ The Lepidoptera of a London Garden ” (7Vmes. ( ’iti/ Land. Knt. Sac., 
i, p. 35). The limits of the “ London J)istrict ” were roughly defined 
by the Council (“ Transactions,” ii., p. 23), having regard rather to 
the convenience of using railway stations as boundaries, than to any 
very definite geographical or geological plan. Dr. Buckell threw 
himself heartily into the work of collecting records in the Lepidoptera, 
and had the assistance of various lists from members of the Society 
and other entomologists, and his list was virtually ready for publicatioii 
in the year 1893. At that time, however, funds werci unfortunately 
not forthcoming for the purpose, and it was not until tlie present year 
(1899) that the way was opened up for publishing the first part. Dr. 
Buckell having in the mean time been comj)elled to give up eiito- 
mology, I have undertaken to edit it, and bring it up to date. 
According to the decision of the Council, records prior to 1880 have 
not been included; this unfortunately shuts out nearly the whole of Prof. 
Meldola’s interesting Leyton records (AW.e AVd. v., p. 173), but tho 
wisdom of the decision can hardly be doubted in view of the vast 
changes which have taken place around London during the past 20 
years. There are still, however, several interesting species left us in 
the neighbourhood of the metropolis, and it is hoped that such a list 
as the present will in the future prove a useful contribution to the 
history of the Lepidoptera round London. 
In arranging the list, I have been reluctantly compelled to retain 
the order of South’s ‘‘ Synonymic List,” as no completed revision is as 
yet in the hands of most of our entomologists ; but I have re-arranged 
the butterflies in accordance with Tutt’s “ British Butterflies.” In 
nomenclature, we are still in our “ transition period,” and I cannot 
hope that the names here employed will in all cases be retained; I 
have simply used those which appear to nie mast likcli/ to obtain cur¬ 
rency, but wherever the specific names difler from those in South's 
list I have placed the latter in brackets for purposes of identification. I 
have, of course, not attempted to work out genera, and except where 
this has to my knowledge already been pretty satisfactorily done, I 
have not disturbed South’s genera, which are mainly those of Guenee 
and Doubleday. 
The following list will indicate our principal sources of information ; 
the catalogues sent us are all MS. except Dr. Fenton’s, which is 
apparently a sejiaratuin from'some paper :— 
A. = AV. J. Ashdown. Richmond and Wimbledon, about 1892-96. 
B. = D. C. Bate, in Knt. Record, vii., p. 301, “ Stray notes on 
the Macro-Lepidoptera of Dulwich.”
