that he had allowed an Amorpha popnli to escape in the twilight 

 one evening, when it was immediately chased by a starling from 

 the roof and caught on the wing. Mr. Buxton said that some time 

 ago Dr. Cockayne had set free a very large number of this species 

 and had thereby attracted all the sparrows of the neighbourhood. 

 It must be noted that A. popnli is not a strong flier. 



Mr. Morford exhibited a number of specimens of Setina irrorella, 

 S. aurita, and its var. ramosa, sent to him by Professor Morel 

 from N. Italy. 



Mr. Ashby exhibited a long series of the rare Buprestid beetle, 

 Agriltts viridis, which he had met with in some numbers in the 

 New Forest. He pointed out the sexual dimorphism in colour, the 

 ^ being green on the under surface of the abdomen and the 

 ? coppery. He said that he found it of no use to beat for the 

 species, the females were taken flj'ing low. 



Mr. Robert Adkin exhibited specimens of Zi/t/icna JilipendidcB, 

 reared in July last from pupse collected in a field at the top of the 

 Downs near Otford, Kent, on the occasion of the Society's field 

 meeting. One of the specimens had only five spots on the upper- 

 side of the forewings, the usual outer sixth spot being absent, but 

 on the underside the position of the missing sixth spot was 

 indicated by a dull red blotch. The black margins of the hindwings 

 were somewhat broader than is usual in Z. fiiipendula, in this 

 respect resembling Z. trifolii, but the fact of the pupae being found 

 high up on a grass stem, and the presence of the sixth red blotch 

 on the underside showed that it could not be the latter species. 



Mr. Newman recorded that a correspondent of his near Brighton 

 had bred some thousands of Z. fxUpendtdir, and amongst them were 

 between twenty and thirty of this five-spotted form, while a large 

 number had the sixth spot only very faintly marked.

Mr. W. J. Lucas read a paper on " British Cockroaches," and 

 exhibited a large number of lantern slides illustrative of his subject.

In the subsequent remarks Mr. Edwards noted that he had 

 observed at Blackheath that Blattella gemianica was gradually turn- 

 ing out the formerly abundant species lUatta oricntaiis, and Mr. P.
