428 
males possessed scales of a peculiar type, known as the “ battle- 
dore ” or “tasselled” scale. Further researches might reveal 
other types. It could very safely be laid down that no female 
possessed a battledore or tasselled scale, hence, wherever found, 
they were indicative of sex. Several other points were advanced, 
and the life history of different moths and butterflies described, 
and the paper illustrated by a collection of insects in their several 
stages, and by microscopic preparations. 
It was resolved that a letter of invitation from the Society to 
the British Association, requesting the honour of a visit to 
Brighton, be forwarded through Mr. Mayall, who had consented 
to represent the Society at Exeter.
