VAmj, IMO. 



Mr. MoLachlan exhibited a gigantio Bpeoies of the family Ephemeriday measuring 

 3 inches in expanse of wings, sent from Veragua. He thought it might possibly be 

 Paling enia Eecuha 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, &o., 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. Xuthus, and P. Xuthulus ; 

 in Japan P. Macliaon 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- 

 tera from Nicaragua and Ecuador." 



The President read " Contributions to a Fauna of the Amazon Valley." 



Mr. McLachlan read a Synopsis of the European species of Panorpa ; and a 

 description of a new species from Java. 



5th April, 1869. H. W. Bates, Esq., F.Z.S., President, in the Chair. 



Mr. Pascoe exhibited curious and interesting forms of Curculionida. 



Prof. Westwood exhibited an example of the new species of Panorpa (P. nema- 

 togaster) from Java, described by Mr. McLachlan at the last meeting ; this was 

 from the Oxford Museum. Also examples of a Blatta (B. melanocephala) which 

 had been found destructive in Orchid-houses in this country. 



Mr. Bond exhibited Sciaphila communana, H. — S., new to Britain, captured in 

 Wicken Fen. 



Mr. Druce exhibited two males of the very rare and magnificent Pa/pilio Zal- 

 moxis from Old Calabar. 



Mr. Smith exhibited a series of British Bomhi, with their respective parasitic 

 Apathi. He mentioned, with regard to B. suUerraneus, muscorum, and lapidariusy 

 that the parasitic Apathi — campestris, vestalis, and rupcstris, 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 considembly 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 Lepidopto-a" 



Mr. Baly communicated " Descriptions of new Phytophaga." 



Dr. Sharp communicated a " Revision of the British species of Hovialota," 

 enumerating and describing 157 species, 29 being ne/Jfr to science.
