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, 
measurmmg 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. Z. 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 Chalcidiz, or metallic-coloured flies, of 
which much must be said afterwards.—Francis Walker.
