Weidel (1911) gives a detailed account of the histology of the gall of disticha, stating that Lacaze-Duthiers (1853) and Küstenmacher (1894) had also studied this gall structure. In my own analysis of Lacaze-Duthiers' paper I question whether precise determinations may be made of the material with which this early author worked.
In Darboux and Houard's publication (1907) of Giraud's Galles de Cynipides, figures 9 and 10 on plate 22 are good illustrations of galls of disticha, altho they were erroneously labelled Cynips agama. Bayer (1908) has pointed out this error and Houard (1908) has confirmed this interpretation.
I suggest that the Réaumur references (Réaumur 1737, Mém. Ins. 3:416, 440, 445, 447, 448, pl. 35 figs. 3, 4) given by several European authors are not interpretable with any certainty as Cynips divisa, C. agama, or C. disticha.
