high degree of parasitism is rather remarkable, but the number of 

 pupae from which these records were made is too small to admit of any 

 genera] conclusions being based on the results obtained. It is, however, 

 worthy of note that last year very few celery plants in Mr Bury's garden 

 were found to be affected by celery-fly larvae, and there may possibly 

 be some relationship between this fact and the high degree of parasitism 

 of the pupae from the last brood of celery-flies of the previous year (191 3). 



A larger number of celery-fly larvae and pupae were collected in the 

 autumn of 1914 at the Agricultural College, Holmes Chapel, Cheshire, 

 and in the neighbourhood of Northcnden, Cheshire, with the object of 

 obtaining results on a larger scale. These larvae and pupae were also 

 found to be heavily parasitised. The complete results of the investi- 

 gation will not be obtainable, however, until August or September, 1915, 

 owing to the period of emergence of the parasites extending over so 

 many months of the year. 



I wish to express my thanks to Mr Claude Morley for naming the 

 Ichneumons (1, 2 and 4), to Professor Dr J. J. Kieffer, of Bitsch, for 

 identifying the Cynipid (3), and to Mr G. T. Lyle, of Brockenhursr. 

 for confirming my identification of the Braconid (5).
