the gall. He named the species A. Gallarum.—E. A. Fitch. 
47. Biorhiza synaspis, Uart.—This gall 
may be found in May on the under side of Fig. 47. 
the leaves of young oaks. It is a green, r.. 
sappy, smooth ball, of from five to seven (“A/G i) 
millimetres in diameter, and attached to the ) ay 
leaf in one spot only. In section it exhibits 
a central larva-cell, surrounded by a thin Bronmiza syvaspts 
inner gall bordering the ‘sappy reticulation, (#”"! i” section). 
In June the gall falls, and assumes a red 
colour; and towards the end of the month, or in July, it is 
pierced by the wingless gall-fly. The specimen figured I 
obtained many years ago from Dr. Giraud (never having 
found the gall myself). It is of a brownish yellow colour, 
covered with numerous red spots.—G. L. Mayr. 
This insect belongs to the Hartigian genus Apophyllus, 
which is separated from Biorhiza, Westw., through having 
one less joint in the antenna than that genus. Hartig him- 
self included this species and Biorbiza aptera both in 
Apophyllus. Since the publication of his ‘ Mitteleurop. 
fichengallen, &c., Dr. Mayr has met with the galls of this 
species in some numbers on Quercus sessiliflora, and more 
rarely on Q. pubescens in September, thus differing from 
Hartig’s time of appearance, who says “the gall falls in 
June.” He also bred from them at the beginning of October 
several specimens of Synergus albipes, H., and S. physo- 
ceras, H,; the latter occurs in no other gall but this, Hartig’s 
specimens, received from Kollar, being bred from “small 
round galls on the leaves of Quercus pubescens.” This_.gall 
has not been recorded as British, but it is doubtful whether 
it does not occur here.—L. A. Fitch.
