Jr riveen the sexes in hardly any of the foregoing cases 
I Pears sufficiently great for this view to he safely ac- 
Ph‘d. Xu some of the cases the brighter tints of the 
male are almost confined to the lower surface, and the

less conspicuously coloured than the females, but

position, colour, size, and of some points of 
^ctnre, has been effected between the two sexes.
