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, Férst., 
Mayr and Haimhoffen bred over two hundred specimens of 
this species, mostly in May and June of the second year; 
Callimome abdominalis, Boh., in March of the second year; 
and C., regius, 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.
