Exhibitions, dr. 



Mr. Jacoby exhibited a species of Aphthonoides, a genus of 

 Halticina, having a long spine on the posterior femora. He 

 also exhibited a specimen of Rhagiosoma madagascariensis, and 

 remarked that it had the appearance of a Longicorn. 



Mr. Stevens exhibited a very dark specimen of Crambus 

 perlellus, from the Hebrides, which its captor supposed to be 

 a new species. 



Mr. Porritt remarked that this brown form of Crambus 

 perlellus occurred at Hartlepool with the ordinary typical 

 form of the species, and was there regarded as only a variety 

 of it. 



Mr. Slater exhibited a specimen of Gonepteryx Cleopatra, 

 which was stated to have been taken in the North of Scotland. 



Mr. Jenner Weir remarked that he had found larvae of 

 Gonepteryx Rhamni upon Rhamnus alatemus (not a British 

 species), and reared them from it. As this shrub was com- 

 monly imported from the Continent for horticultural purposes, 

 it seemed to him probable that the eggs or young larvae of 

 Gonepteryx Cleopatra might be easily introduced. He further 

 observed that the deposition of its ova by Gonepteryx Ehamni 

 on Rhamnus alatemus was a remarkable instance of instinct ; 

 for although the shrub in question was undoubtedly a suitable 

 food-plant for the species of Gonepteryx, it was very unlike 

 the two common species of the genus Rhamnus— frangula and 

 catharticus — both in appearance and character, being an ever- 

 green with bright glossy leaves, and the two latter species 

 being deciduous. 



Mr. South exhibited an interesting series of about 150 

 specimens of Boarmia repandata, L., bred in 1876 and during 

 the present year from larvae found feeding on bilberry 

 and heather in a small wooded glen on the coast, not far 

 distant from Lynmouth, North Devon. Mr. South remarked 

 that the present sylvan character of the locality might to a very 

 large extent be considered artificial, inasmuch as the oak trees 

 which now contribute so greatly to its beauty were without 

 doubt planted. Prior to the introduction of the oaks probably 

 the only arboreous plants which existed there were birches 

 and sallows, similar to those now observed in some other
