handed over to him, along with the specimens, by Mr. T. H. 

 Grosvenor, the antenna of the specimen shown had been 

 amputated near the base when the insect was in its first or 

 second instar. In a second specimen of the same series, 

 which is still alive in the Natural History Museum, regenera- 

 tion of exactly the same kind had taken place. In each case 

 two or three tarsal joints, including the claw-joint, with its 

 claws and pulvillus, are quite distinct, and their character is 

 unmistakable. 



The Chalcid Syntomaspis druparum Dalm., bred by 

 Mr. Hamm, from hawthorn seeds in birds' droppings. — 

 Prof. PouLTON, exhibiting the seeds and Chalcids (Tory- 

 midae) which had emerged from them, said that Mr. A. H. 

 Hamm's observations recorded below were prompted by 

 Dr. J. Waterston, who had kindly determined the species 

 referred to in this and the following note : — 



" Between November 17 and December 16, 1919, over 

 2000 hawthorn seeds from birds' dro2)pings were collected from 

 under hawthorn trees in the grounds of the Oxford University 

 Museum. The seeds had almost certainly come from black- 

 birds, which were constantly seen picking and eating the 

 fruit. By December 17 nearly all the berries had been 

 stripped and the trees were deserted. 



" The seeds, separated from extraneous matter, were looked 

 at from time to time up to the present date (March, 1922), and 

 on August 26, 1921, a single female Chalcid had emerged and 

 was found dead. It could only recently have died, as I was 

 enabled to set it with scarcely any relaxing. 



" A number of uneaten berries accidentally dropped by 

 the birds in plucking from the trees, were also collected. 

 These have been looked at from time to time, but nothing 

 has so far emerged from them. 



" In the course of a walk near Old Hincksey, Oxford, on 

 December 13, 1919, a number of birds' droppings containing 

 hawthorn seeds were j)icked up, several missel-thrushes 

 being disturbed feeding during the search. Looked at 

 occasionally since December 1919 a single female Chalcid 

 was found alive on June 15, 1921. 



" I have since separated the seeds from the other matter
