together in the middle. The basal half is in shape like a 
round cushion, is five millemetres in diameter, and from two 
to three millemetres in height. Its regular development is 
prevented by the petiole producing an impression, into which 
the stalk is pressed. The surface of the lower half is red- 
brown, and generally distinctly reticulated with the darker- 
coloured epidermis, which, in the development of the gall, 
becomes cracked in that manner. The 
epidermis itself is covered with scat- 
tered, moderately long, fine, woolly, 
white hairs. On the cushion-shaped 
basal part rests the almost bud-like 
upper part: the base of this part is 
quite as thick, and of the same shape, 
as the basal part of the gall itself; 
towards the top, however, it is pro- 
longed into a short conical point, and 
into one or several fibrous projections, 
which are generally again divided before 
attaining the top; this upper part of 
the gall is covered with short woolly 
hair, and shows at its lower, swollen 
part a coarse longitudinal striation. In 
section, the inner gall is found con- 
2 tained in the cushion-shaped basal 
Cynirs GALEATA, part, and is united with the substance 
of the gall all round. The bud-shaped 
upper part is filled with a brown cellular tissue. This gall is 
found on the weak twigs of shrubby Quercus pubescens and 
Q. pedunculata. Neither Dr. Giraud nor myself was success- 
ful in obtaining the gall-ly.—G@. LZ. Mayr. 
In a note appended to his description of the gall, Dr. Mayr 
gives a description of the gall-fly from a dead, but mature, 
specimen, cut out of a gall. All the galls obtained by 
Dr. Giraud were empty but two, and they contained the 
larve of a Callimome. Dr. Mayr bred Ceroptres arator, but 
probably from the twig, and not from the gall. The species 
does not occur in Britain. —Z. A. Fitch.
