Exhibitions, dc. 



Mr. C. 0. Waterhouse remarked on the great changes which occurred 

 in the colours of insects from exposure to light, changes so startling that 

 they would certainly mislead anybody not cognisant of the fact; as a rule, 

 brilliant fiery red became changed to bright green, blue to black, green to 

 purple or purplish brown, and pale yellow to light brown. In illustration, 

 Mr. Waterhouse exhibited certain specimens of the following Coleoptera 

 before and after exposure in the show-cases of tlie British Museum: — 

 Eurhinus cvpratus, IHig., Poropleura bacca, Kirby, Euinolpus ignitns, Fal)r., 

 Doryi^hora cincta, Germ., and Omoplata aulica, Bob. 



Mr. W. L. Distant remarked that from this cause quite recently old 

 and exposed specimens of Lepidoptera had been described as new species.
