INTRODUCTORY PAPERS ON IGHNEUMONID®. 225 
Platypteryx falcula and one male Geometra papilionaria. I 
observed large numbers of the larva of Bombyx callune sunning 
themselves on the heaths, but they were all ichneumoned. On 
the bank facing the Inn A. aglaia was flying in plenty, and without 
any trouble I caught two dozen in one morning. 
As many of my friends who have spent their holidays in the 
South of England met with much disappointment, I hope that the 
above notes will prove of interest to some of the readers of the 
‘Entomologist’; and although the list of captures is not extensive, 
yet it will show that species were not totally absent, as has been 
the case in the New Forest.
