British Braconida. 41 



A ? was taken near Norwich by Bridgman, May 24th. 

 The species is now first noticed as British. Beared 

 abundantly by Beissig, Tischbein, and Brischke from 

 galls of Andricus terminalis, Fab., that had been kept 

 during the winter, making its appearance, with many 

 other parasites, at the end of May. Walker records a 

 specimen of a Bracon which he bred in March, and 6 

 more in May, from the same galls collected near South- 

 gate (Zool. iv. 1456). 



The following species (or variety?) should also be 

 found in England. B. longicaudis, Ratz., Ichn. d. Forst., 

 iii., 38. Abdomen wholly pale, except the 1st segment ; 

 terebra longer than that of B. caudatus. 2 . Length, 

 1^ ; with the terebra, 2| Hn. Bred by Nordlinger at 

 the end of May from galls upon young oak-shoots (the 

 species not mentioned). B. caudiger, Nees (Mon., i., 

 77, 103, $ ) is stated by that author to have been found 

 July 4th, by Gravenhorst " in Silesise quercu," and with 

 caudatus, Batz., forms a section of the present genus 

 with a speciality for oak-galls, and furnished, like Calli- 

 mome, with an unusually long ovipositor, to enable them 

 to reach the inhabitants of those excrescences.
