immanata, and stated that he had never before seen such a 
wonderful collection of varieties of a single species. Mr. 
McLachlan exhibited, for Mr. G. Lewis, living specimens of 
Paussus faviert (Fairm.), lately collected in Portugal by Mr. 
Lewis. ‘The Rev. W. W. Fowler exhibited Staphylinus latebricola 
and Quedius truncicola, both from the New Forest. The Secretary 
exhibited, for Mons. H. de la Cuisine, of Dijon, coloured draw- 
ings, life-size, of a variety of Urania cresus, and a variety of 
Papilio memnon; and Prof. Westwood made some observations 
on them. Mr. G. Elisha exhibited specimens of Antispila 
pfeiferella, together with the cases, and the leaves mined by the 
larve. Mr. J. W. Slater read a paper ‘‘ On the Origin of Colours 
in Insects,” in which he showed that the assertions of Mr. Grant 
Allen, that all brightly-coloured insects were flower-haunting 
species, were incorrect; and that many brilliantly coloured 
insects were carnivorous. Mr. M’Lachlan said that the physio- 
logical question in connection with colour had not been paid 
attention to; he thought that colour in insects was to a great 
extent dependent upon the circulation of fluids in their wings. 
The discussion was continued by Prof. Westwood, Mr. Goss, The 
Rev. W. W. Fowler, Mr. Jacoby, and Mr. Weir.—-HERBERT Goss,
