after the manner of fern fronds. Should the galls not occur in 
a mass the leaf becomes better developed, and the spherical 
galls may be seen projecting equally on each side of the leaf. 
If the galls appear on the upper side of the midrib, which 
frequently is the case, then the lower side of the vein swells, 
turns upwards and forms acurl. The galls occur between 
the crumpled and generally up-turned sides of the leaf in a 
central longitudinal furrow, which becomes formed in that 
manner: they are sappy, when recent, green or red in 
colour, and on the lower side scantily, on the upper side 
more thickly, covered with hairs. When mature the galls are 
hard and yellow; those galls which do not occur on the 
midrib are less conspicuous on the under side of the leaf. 
The section exhibits a hard inner gall, which is thoroughly 
united to the exterior gall substance. The dark-coloured 
males appear towards the middle of June (later in a cold 
summer), and after them the rufous females—G. LZ. Mayr. 
Dr. Mayr bred two females of Ceroptres Cerri in the 
summer from fresh galls.— LZ. A. Fitch.
