Diasticticus species.— Mr. E. A. Newbery, the coleoptera Dias- 
ticticus vulneratus, a species new to Britain, and Diasticticus com- 
planatus, a species lately discovered which had hitherto escaped 
detection amongst D. pristonychus in most collections. 
Geometrid.e from Locarno. —Mr. L. B, Prout, some Geometrician 
collected by Dr. Chapman at Locarno. 
Leucoma chrysorrhcea webs.— Mr. A. Bacot, spun webs of 
Leucoma chrysorrhoea containing hibernating larva?, taken from 
hawthorn at Pegwell Bay, Kent. Mr. A. W. Mera remarked, on 
this last exhibit, that he had taken the larva? at Stanford, Essex, 
which was away from the sea. Mr. F. J. Hanbury said he had seen 
the imagines of this species sitting on bare black rocks near Torcross, 
and that it was, in such a position, observable a great distance off. 
Discussion on Establishment of a Central Entomological 
Exchange Club. —Mr. F. J. Hanbury brought before the members for 
discussion the matter of a Central Entomological Exchange Club for 
the British Isles, to be conducted on similar lines to the existing 
Botanic Exchange Club. The proposed rules of the club were read 
out, and commented on where alteration was necessary in order to meet 
the demands for the different matter for exchange. It would not aim 
at doing away with private exchange, but would facilitate the inter¬ 
change of even common species from outlying and very varying locali¬ 
ties. It would save correspondence, time, and postage, and would 
serve to supply all with local forms ol very many species. He said 
said that none except very rare species should be distributed, unless in 
first-class condition. The rate of exchange was a difficult matter, in 
view of insectshaving a money value, and he would suggest that some 
reliable dealer’s list, such as Harwood’s, of Colchester, might be used 
as a standard. Rare species would be exchanged for rare species, and 
not for a collection of lower priced insects which, together, would equal 
the price of the rarity. There should be, he thought, at least two dis¬ 
tributors, who would take their turn by rotation, out of the list of 
members. Last, but not least, a report should be printed at the end 
of every year, containing such notes as were worth publishing concern¬ 
ing the insects distributed during the year. An alternative scheme was 
suggested, whereby members of the club should meet four times a year, 
a list be printed of all the species for distribution and sent to each 
member, and each member then attend with his quota of insects. 
The matter being open for discussion, Mr. Prout asked how the rate of 
exchange was arrived at in botany, where dried plants practically had 
no money value. Dr. Chapman thought the price was bound to be 
fixed for lepidoptera. Mr. Kaye thought that specimens not comply¬ 
ing with the rules, instead of being destroyed, might be returned, as 
sent, to their respective owners. Mr. Shaw alluded to the various 
styles of setting and the varying nomenclature, each of which would 
cause some difficulty. He thought that anyone should he allowed to 
join the club if he or she complied with the conditions of membership. 
Mr. Sich wished to know how the difficulty would be met of finding 
the distributor or distributors. Mr. Hanbury answered this last 
query by saying that the leading men would take their turn as in the 
Botanical Club. Mr. Riches supported a self-contained club in the 
Society itself. Mr. Fuller thought that a small Exchange Club in 
the Society would never grow into the larger body. Mr. Bell asked
