structural difierences between the antennae of these closely 

 allied species. In defoliaria the pinnae are very short, but 

 there are two pairs on each joint; whereas auranliaria (with 

 the remaining British members of the genus) has a single 

 pair of elongated pinnae on each joint. A preparation of the 

 two antennae was exhibited under the microscope. 



The Rev. F. D. Morice and other Fellows gave parallel 

 instances of dilTerence of antennae in the case of closely related 

 insects.

 be present, but that a statement of his views was given in

Prof. Poulton read a further statement from Sir George 

 Hampson, but took no part in the discussion.
