At the meeting of the Scientific Committee held on 25 May,

Mr. MacLachlan reported that the spindle-shaped gall, sent by Baron Von Mueller, was probably the work of a cynips, which had perforated the young flower-buds. Some of the galls contained a larva of a dipterous insect, itself attacked by a parasitic hymenopterous insect (Gardeners' chronicle, 29 May 1880, p. 694).

See also a more extended discussion by MacLachlan [signed McLachlan], with figure, of these galls in Gardeners' chronicle, 25 September 1880, p. 404 (fig, p. 405). The article reports that the specimens of gracilis from Spencers Gulf (SA) had been sent to M by O. Tepper (letter not found).
