these few remarks, showing the possibility of rearing Lepidoptera from imported pupae, 

 in the hope that some of our collectors may be induced to try this mode of enriching 

 our native Fauna. Whether such artificially-reared species would, if set at liberty, 

 propagate themselves is a question which entomologists resident in Britain must set 

 at rest. I have not myself had facilities for settling this point, but I have, I trust, 

 shown the possibility of introducing foreign species into our country. We have suc- 

 ceeded in destroying some of our native species, e.g., Chrysophanus Chryseis and C. 

 Dispar, which appear to have become nearly if not quite extinct ; and may it not 

 be worth while to see whether we cannot enrich as well as impoverish our native 

 Fauna? 



"The specimens which I have had the pleasure of exhibiting this evening will 

 prove the truth of my assertion, that they do not offer any variety or deviation from the 

 ordinary types of the species, and they will at the same time disprove the ancient and 

 oft-quoted opiuion, that Lepidoptera, unless reared in their natural state and under 

 their natural condition of temperature, are never properly developed.'' 



Mr. Pascoe, after announcing the appearance of Professor Lacordaire's sixth 

 volume, containing the Curculionidae, and speaking in terms of admiration of the 

 author's masterly treatment of the subject, took the opportunity of stating that 

 Lacordaire was in error in supposing that Eurhamphus fascicularis was confined to 

 New Zealand, as he knew species to occur also in Australia. 



It was announced that Mr. B. T. Lowne's entomological excursion to Bahia was 

 abandoned, and that two Messrs. Wilson of Adelaide (cousins of Mr. Alfred R. Wallace) 

 were about to make a natural-historical exploration of the islands to the east of New 

 Guinea.
