 P. Curtis. 



Date. — June 29th, 1913. Sex.— <? and 2. 



Place, — Bere Wood, Dorset. Duration. — 20 minutes. 



Food. — A bird came to an oak tree and hovered up and down looking 

 under the leaves. It fluttered the leaves as it flew, and a Tortrix viri- 

 dana popped out and was caught in flycatcher style. Immediately the 

 mate of this bird came and hovered in front of the foliage in the same 

 way, then darted in and caught another T. viridana in the leaves. They 

 then both hopped about in the leaves and got a few small micros of a 

 grey colour, which it was impossible to identify. I can only say they 

 were about the size and appearance of Jnephada subjectana, but I do 

 not attempt to name them even to giving them a family. After that 

 the birds went off.
