d02 [May, 1869. 
Mr. McLachlan exhibited a gigantic species of the family Ephemeridce, meaauring 
3 inches in expanse of wings, sent from Veragua, He thought it might possibly bo 
Palingenia Hecuba of Hagen. 
Mr. F. Smith exhibited the new British Bee, Colletes cunicularia, collected in 
the Isle of Wight by Mr. Cooke, jun. 
Mr. Butler exhibited varieties of several European Butterflies, captured by 
himself in Switzerland. 
Mr, Stainton mentioned that in the neighbourhood of Mentone, &c., early in 
the year, Vanessa Atalanta was the commonest butterfly, and scarcely appeared to 
hybernate, whereas in England hybernated examples were rarely seen until the 
early summer. 
The President exhibited a collection of Papilios from Japan, sent to him by 
Mr. Ward, of Halifax. They consisted of P. Machaon, P. Xuth^is, and P. Xuthulus ; 
in Japan P. MacJiaon was very variable, and shewed a tendency to approach its 
allies in coloration, whereas in Europe it was very constant. He looked upon that 
country, therefore, as the one which was the most favourable to the formation of 
incipient species in this group. For comparison he had added examples of the 
allied P. Zelicaon and P. Asterias, from N. America. 
Mr. Hewitson communicated " Descriptions of new species of Diurnal Lepidop- 
iera from Nicaragua and Ecuador." 
The President read " Contributions to a Fauna of the Amazon Valley."

Wicken Fen. 
Mr. Druce exhibited two males of the very rare and magnificent Papilio Zal- 
tnoxis from Old Calabar. 
Mr. Smith exhibited a series of British Bomhi, with their respective parasitic 
Apathi. He mentioned, with regard to B. suhterraneus, muscorum, and lapidarius, 
that the parasitic Apathi — ca')Yvpestris, vestalis, and rupestris, exhibited all the grada- 
tions of variation common to their respective foster-parents ; whereas with B. pra- 
torum, a moss-builder, the parasitic Apathus Barhutellus was considerably different. 
This latter Bomhus was, however, a very good-tempered bee, whereas the others 
were very irritable ; hence the non-necessity of exact mimicry. 
Mr. A. R. Wallace read " Notes on eastern Butterflies." Mr. Hewitson read 
«' Descriptions of new species of Diurnal Lepidoptera" 
Mr. Baly communicated " Descriptions of new Phytophaga." 
Dr. Sharp communicated a " Revision of the British species of Homalota"
