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 a curl. 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. L. Mayr. 



Dr. Mayr bred two females of Ceroptres Cerri in the 

 summer from fresh galls. — E. A. Fitch.
