Mr. Hewitson sent for exhibition a selection from a large number of butter- 

 flies collected in Ecuador by Mr. Manuel Villagomes. The whole collection 

 comprised 2000 specimens in perfect preservation, and the new species are 

 described in the paper mentioned below. 



Mr. F. Smith exhibited a collection of Japanese Hymenoptera (also a few 

 Coleoptera and Diptera) made by Mr. Geo. Lewis at Nagasaki. The Hymen- 

 optera included a few Ichneumonidse, but the principal part of the collection 

 consisted of Aculeata, of which there were forty-four species, and of these about 

 twenty appeared to be undescribed. The Apidee consisted of one new species 

 of Prosopis, two of Halictus, and five of Megachile (two of which have also been 

 found in China) ; also one species of Lithurgus, one of Stelis, two of Ccelioxys ; 

 one undetermined species of Xylocopa, one Bombus (undetermined, but pro- 

 bably described), and lastly, one honey-bee, the Apis nigrocincta, also found in 

 China, the queen of which was not distinguishable from Apis mellifica, though 

 the workers were perfectly distinct. Of Fossorial Hymenoptera, there were a 

 new species of Pompilus, Priocnemis dorsalis (also found in China, Java and 

 India), a species of Agenia, an undescribed species of AmmophUa, three species 

 of Pelopaeus, including P. deformis, found also in China, and P. bengalensis, 

 a widely distributed forai, found in India, China, Singapore and most of the 

 Islands of the Eastern Archipelago ; Sphex argentata, perhaps the most widely
