FIFTY YEARS ENTOMOLOGY IN BRISTOL. 
of Micro-lepidoptera to the British list, including Anacampsis 
sirco?nella, named after him by Mr. Stainton. 
In 1852 Dr. John N. Duck, of Portishead, wrote a book entitled 
1 i The Natural History of Portishead, ' ' containing a list of insects, 
birds, and wild flowers found in that neighbourhood. His collec- 
tion of Lepidoptera was given to the Bristol Museum by his sister. 
Beside the above, we find in the records of the Entomological 
Section the names of Messrs. R. Aldridge, L B. Baron, J. Butler, 
W. N. Cooper, W. Derham, S. F. Hudd, 6. Hunt, J. Hutchins, 
G. James, R. Last, W. K. Mann, R. Mayes, J. Mountney, A. 
Nash, A. C. Pass, T. H. O. Pease, J. Preston, E. Prichard, R. V. 
Sherring, W. A. Smallcombe, E. Spencer, G. Thomson, J. Wallis, 
C. Wheeler, T. H. Yabbicom, Colonel Couchman, and Major 
Broughton, all of whom have helped in extending our knowledge 
of the Entomology of the Bristol District. 
As already mentioned, the number of species of Lepidoptera 
found in our district is large, being some 1,300, out of about 2,000 
species in Britain, but many of those occurring are rare, and our 
localities seldom afford the very great abundance of specimens 
often met with elsewhere. The last few summers in particular 
have been remarkable for the small number of examples of butter- 
flies met with, if we except the pretty holly-blue Lyccena argiolus, 
which has of late become more common in our district. One 
butterfly has, during the period under review, entirely disappeared 
from the country-side. This is the Black- veined White, Aporia 
cratcegi, which was at one time fairly abundant in certain localities, 
but has not been found in this district for many years, and even 
in Kent, where it was last recorded, it is extremely doubtful 
whether it still exists. 
The Bristol District is the only one in Britain which possesses 
all the species of the genus Drepana; this includes our rare 
" hook-tip" D. sicula (harpagula) which Messrs. Harding, Butler, 
Ficklin, Grigg, Mann, Bartlett, and the writers of this paper have 
taken in Leigh Woods. The eggs of the moth have been obtained, 
the larva figured and described, and the species on several 
occasions bred in fair numbers, but its occurrence is still very rare 
and for some years past no capture has been recorded. Still, 
we may hope that this, our exclusive possession, so far as Great 
Britain is concerned, may yet be preserved to us. 
Our local Acidalia, A. holosericata still maintains its position in 
fair numbers in its very restricted locality on Durdham Down, and 
another Geometer, Bapta temerata, has during the last two or three 
years become more common. 
Amongst the Noctuidse may be mentioned the capture of a very 
dark female specimen of Heliothis armigera by Mr. J. W. Clarke 
in 1867, of Heliothis scutosa by Mr. Jones at Weston-super-Mare 
in 1876, of Catocala fraxini by Mr. Griffiths in Leigh Woods in
