 the leaves. From galls kept in a room the flies appeared

The inquilines and parasites of this species, given by 

 Mayr, are as follows : — Synergus pallicornis, H., in the 

 spring of the second year; Syntomaspis lazulina, Forst., 

 Mayr and Haimhoffen bred over two hundred specimens of 

 this species, mostly in May and June of the second year; 

 Callimorae abdominalis. Boh., in March of the second year; 

 and C. regins, Nees, from March to June of the second year. 

 Mayr also notices an interesting case in which he collected a 

 specimen of this gall on July 18th, then quite immature, 

 which produced Synergus pallicornis in the following spring.
