Prof. PouLTON said it would be remembered that Mr. W. A. 

 Lamborn had observed the stroking of the hind-wing brands 

 by the anal brushes of the male Amauris niavius, L. (Proc. 

 Ent. Soc, Lond., 1911, xlvi, xlvii), and A. egialea, Cram. (1912, 

 xxxiv, XXXV ; 1913, Ixxxiii, Ixxxiv). Dr. Carpenter had now 

 carried these observations a stage further, by showing the 

 manner in which the brushes, presumably charged with scent 

 from the brands, were employed in courtship. The relative 

 positions of the two insects suggested the possibility that the 

 antennae of the female were the sense organs stimulated by 

 the odoriferous powder. It was most satisfactory that these 

 valuable observations in the field should throw so much light 

 upon, and receive so much light from, Dr. Eltringham's 

 admirable investigations in the laboratory.
