several galls were formed unusually, viz. outside of the culm. Yet both T. giraudi and the parasitoid E. palustris were reared from them, like from normal galls.
Above the 2nd or 3rd node there are several larval chambers in the culm, one above the other, each with one larva or pupa. The culm is locally sclerified, and its weak swelling is almost hidden by the surrounding leaf sheath.
Schedonorus arundinaceus subsp. orientalis, giganteus, pratensis.
