YORKSHIRE HYMENOPTERA IN 1879, 1880 AND 1881. I09 



Faviily BRACONID^. 



X Bracon variator iW^^. Askham Bog near York, taken (in 

 the cocoon I believe) by Mr. Charles Smethurst at the Y. N. U. 

 excursion (Bairstow). 



Apanteles glomeratus (L.) It is interesting to know, 

 as I have observed in another place, that I have bred this parasite 

 from the larvae both of Pieris brassicce and F. rupee. Dr. Vollen- 

 hoven informed me that there could be no doubt of the identifi- 

 cation in both cases. He had himself observed the same fact 

 (Bairstow). 



X Microgaster globatus (L.) Received from S. L. Mosley 

 and G. T. Porritt (Bairstow). 



Tribe OXYURA. 



We have now for the first time to record the names of 

 Yorkshire species pertaining to this group, Mr. Peter Cameron, of 

 Glasgow, informing me that he has 



X Lagynodes pallidus (Boh.) and 



X Gales US clypeatus Thorns., both from Scarborough. 



Tribe FOSSORES. 



The following captures were made near York during the 

 season of 1881 : 



Nysson spinosus (Fab.) One example, Holgate (Wilson). 



Gorytes mystaceus (L.) Three on the umbels of 

 Heradeinn sphondyliuni, Poppleton (Wilson). 



Crabro cribrarius (L.) One on an umbelliferous plant,
