38 FIFTY YEARS' ENTOMOLOGY IN BRISTOL. 
of Insects, especially Hymenoptera and Diptera. Collections of 
both these orders containing many local species have been pre- 
sented by him to the Bristol Museum, but perhaps his most 
valuable and permanent achievement has been his "List of the 
Diptera of the Bristol District " (Proc. B.N.S., ser. IV., Vol. III., 
part II.). This contains records of 690 species, and will form the 
basis for any future work done in this much neglected order in 
our district. 
Mr. Robert Ficklin collected Lepidoptera in the Bristol District 
from about 1870 to 1890, and in 187S discovered Eupithecia 
jasioneata, at Lynton, North Devon, a species new to science. 
Mr. W. H. Grigg joined the Society in 1870, and from that date 
until 1890, worked strenuously at the Lepidoptera, including 
Tortrices and Tineina, in both of which groups he was very 
successful in breeding many little-known species. He gave up the 
study of Entomology about 1S90, and his fine collection was broken 
up ; the Micro-lepidoptera, however, passed into the possession 
of Mr. Griffiths. 
Mr. George C. Griffiths, F.E.S., became a member of the Bristol 
Naturalists' Society in 1872 and was elected President of the 
Entomological Section in 1899, which office he continues to fill. 
He joined the Entomological Society of London in 1888 and con- 
tributed a paper to its Transactions in 1898 on "The Frenulum 
of the Lepidoptera."* He also made detailed examinations of the 
Frenulum for the late Mr. J. W. Tutt's book on the "British 
Lepidoptera, as follows : — Psychides (in Vol. I.); Sphingides (in 
Vol. III.), and Alucitides (in. Vol. V.). Mr. Griffiths has a very 
extensive collection of Lepidoptera, both British and Exotic, many 
rare and interesting specimens from which he has exhibited at 
meetings of the Society and of the Entomological Section. 
He has done much valuable work at the Bristol Museum in 
arranging and classifying the very large collections of Insects 
presented to that Institution by Lady Smyth, of Ashton Court, 
and others. His collection of British Lepidoptera, which includes 
the Tortrices and Tineina collected by Mr. W. H. Grigg, of Bristol, 
is probably one of the most extensive private collections in the 
West of England. 
A. E. H. 
Dr. C. K. Rudge, President of the Society from 1904 to 1906, 
has studied the Orders Diptera, Hymenoptera and Hemiptera, also 
the Mollusca. 
Mr. Edwin Wheeler collected Coleoptera and Lepidootera from 
1870 to 1890 and made many beautiful drawings of the eggs of 
* Note. — The "Frenulum" is the loop and bristle which connects the 
fore and hind wings of many of the moths.
