black form, and Xotolophus antiqua, large specimens from Aberdeen¬ 
shire. 
Aporophyla lutulenta.— Rev. C. R. N. Burrows, a fine series of 
Aporophyla lutulenta showing all the phases of variation including the 
form consimilis of Stephens. 
Discussion on Sugaring.—A discussion on “ Sugaring” was held. 
Mr. Prout in starting it said that it had never been satisfactorily 
settled what were the conditions, atmospheric and the like, that 
were essential to success. He remarked that Mr. Robson began 
collecting data, but had not as yet made any generalisations thereon. 
It appeared pretty certain that certain conditions suited certain families. 
One knows of evenings for Tortrices, for Pgralidae, &c., and Mr. Prout 
had himself had particular evenings when Nomophila noctuella swarmed. 
Other remarks put forward by the President were, that on rare occasions 
he had observed insects paired on sugar and that for some unaccount¬ 
able reason he had always found certain trees, even of the same kind, 
were always more productive than others. Mr. Burrows said he had 
never seen insects paired at sugar. He thought he had good proof 
that insects came a considerable distance to visit the sugar as he had 
repeatedly found that when the wind was in certain directions he always 
got the same insects, such as when the scent blew over reed-beds he 
got reed-frequenting species. Dr. Sequeira said he had found that 
when sugar was productive light was not, and vice versa. Mr. Burrows 
then asked members for their experiences with Luperina testacea. He 
personally had only twice found it on sugar. Mr. Prout said he had 
only once seen a 5 , but Mr. Cox mentioned that he had taken a series 
off sugar. Mr. Nicholson spoke next, and in the course of his remarks 
stated that Mr. Bright, of Bournemouth, had on occasions applied 
sugar to oak trunks in the early morning to attract Limenitis sibylla. 
Horse-chestnut was, he considered, one of the few trees that never pay 
for sugaring. Asa general rule all trees were worth a trial. Autumnal 
insects he thought were less particular about the atmospheric conditions, 
than others, as they come on almost any night. Mr. Kaye said in 
answer to this that the air was always more humid at that time of 
year and the scent therefore travelled better. Dr. Chapman, in refer¬ 
ring to atmospheric conditions in general, said it was certain with 
regard to the attractiveness of sallow bushes that a clear sky was always 
accompanied by a dearth of insects. 
Dec. 4th, 1900.— Annual Meeting.— Mr. Alfred Sich, of 65, 
Barrowgate Road, Chiswick, was elected a member of the Society. 
Cid aria immanata. —Mr. Clark exhibited a number of Cidaria 
immanata from Aberdeenshire. Mr. Prout remarked about these that 
although so varied they could not be mistaken for the Shetland forms. 
Taleporia tubulosa (pseudobombycella) cases, etc.— Mr. Kaye, 
some cases of Taleporia tubulosa taken at Oxshott on birch trunks, also 
a specimen of the rare Morpho godartii from Bolivia. 
Camptogrammabilineataaberrations. —Dr. Sequeira, along variable 
series of Camptogramma bilineata from Devon, Kent, Aberdeenshire, 
&c. 
Ciieimatobia boreata.— Mr. Pickett, some living specimens of both 
S and J Ciieimatobia boreata from Chislehurst.
