Rare British Beette.—Mr. Bedwell exhibited a specimen of the 
beetle Otiorrhynchus ligustici, L., taken near Ventnor, one of the rarest 
of the British weevils, of which there has been no recent record. 
Fiuorescence in Leproprera.—Drs. J. C. Mottram, F.Z.S., and 
HK. A. Cockayne, D.M., F.R.C.P., gave a demonstration of fluorescence 
in Lepidoptera by ultra-violet radiation. In view of the interest which 
physicists have taken in the brilliant coloration of many birds and 
insects in an endeavour to explain them on a physical basis, 1t occurred 
to us that an examination in ultra-violet radia would go far to 
decide whether or no fluorescence played any part in these brilliant 
colours. A number of representative British and Tropical Lycaenidae, 
some Pyrales which showed a mother-of-pearl iridescence, etc., were 
examined, but none of these showed any fluorescence. Most of the 
British moths and a large number of Tropical butterflies and moths 
belonging to widely different groups had been examined, but only a 
very small proportion proved to be fluorescent. ‘The glistening yellow 
hindwings of Troides (Ornithoptera) helena and 1’. darsius, Gray, were 
very fluorescent, as were the yellow markings of 7. haliphron and T. 
remus. The duller yellow of the females was less fluorescent than that 
of the males. The yellow on the abdomen of the males of 7. alexandrae,. 
T. poseidon, T. urvilleana, Guér., and T. croesus, Wall., and the thin 
yellow areas on the hindwings of the last-named species were fluores- 
cent, but the other brightly coloured portions were non-fluorescent. 
Other fluorescent species were Opisthoyraptis luteolata, Dup., Scoria 
lineata, Scop. (dealbata, L.), Aspilates gilvaria, F., Ourapterya 
sambucaria, li, Hepialus humuli, L. (male), Hylophila bicolorana, Fuesl. 
(white hindwings), Halias prasinana (white hindwings of female), 
Cyaniris argiolus, Li. (undersides slightly fluorescent). It is interesting 
that the white males of H. humuli from the Shetlands are much less flu- 
orescent than English ones, those with red markings on a white ground 
only very slightly fluorescent, and those coloured like females are non- 
fluorescent. It is so light when the males fly in the Shetlands, that 
the white coloration and fluorescence are not of much use. In the 
case of the Geometers both sexes are equally fluorescent. All are 
light-coloured and therefore conspicuous on the wing at dusk, and 
their fluorescence must add to their visibility. 
Hering Forrst.—The Secretary read a letter from the Essex Field 
Club protesting against a Parliamentary Bill for the permanent aliena- 
tion of parts of Wanstead Flats and Epping Forest for allotments, and 
on his motion, seconded by Lord Rothschild, it was unanimously 
resolved to send a letter in similar terms to the Prime Minister, and 
others who might be interested in supporting the protest.
