Papers read, dc. 



Mr. J. W. Slater read the following paper " On the Origin of 

 Colours in Insects " ; — 



" It may not be time lost to examine, as far as insects are con- 

 cerned, a very plausible theory of the genesis of colour in the 

 animal world, especially as it has gained no small degree of 

 popularity. The theory in question is that of Mr. Grant Allen, 

 as promulgated in his work, ' The Colour Sense, its Origin and 

 Development ; an Essay on Comparative Psychology.' He there 

 contends that the most beautiful insects are such as haunt flowers 

 and fruits, either feeding directly upon their pollen, nectar, sweet 

 juices, &c., or preying upon minute insects which are attracted 

 there for the same purpose. To quote Mr. Grant Allen's own 

 words: — 'Only those animals display beautiful colours, due to 

 Sexual Selection, in whom a taste for colour has already been 

 aroused by the inllueuce of Howers, fruits, or brilliant insects, 

 their hahitual food.'
