Excerpt from The Entomologist, Vol. 7 Against each other (as is also the case in Cynips Ter ricola), forming altogether a brown mass, on the extreme of which the outline of each separate gall is readily to be perceived. When recent this gall is said to be succulent, but when dry its section exhibits a reddish mass of cells, divided from each other by their septa. Harting states these galls have but one cell, but on investigation I find that the smaller or pea-sized specimens possess from one to three cells, and the larger or cherry-sized galls from three to five, or in some instances as many as nine; these larger cells are oval, measurrng seven millemetres in their longest, by six mille metres in their shortest, diameter, and are enclosed in a pale yellow, softish, thinly-walled capsule, which is throughout firmly united with the substance of the gall. - G. L. Mayr. The existence of Biorhiza aptera, whose gall has been often found on the roots of oak-trees in the south of England, is liable to be shortened by the introduction of the germ of a new life within it, as it is not secure from Callimome Roboris, one of the gorgeous Chalcidiaa, or metallic-coloured flies, of which much must be said afterwards - Francis Walker.
