25. Cynips amhlycera, Gir. (C. cor- 

 ruptrix, Schlechtendal). — This small 

 gall, four to five milleraetres long, 

 consists of a short, cylindrical part, 

 which contains the larva-cell : this part 

 bears two or three oblique, stout, short, 

 conical projections, which are either 

 turned upward and outward, or only 

 outward. At the point opposite the 

 basal attachment we generally find a 

 small wart, which is surrounded by a 

 dense, woolly, short crown of hairs (in 

 those specimens which have three cones 

 the wart is in the centre of these three). 

 The surface of the gall is red-brown 

 and smooth. In section it shows a large, 

 thin inner-gall, which is grown together 

 with the thin wall of the cylindrical part of the gall, 

 and does not extend into the cones, these being filled with a 

 moderately dense parenchyma. The fly appears in May of 

 the next year. — G. L. Mayr. 



This species has not been found in Britain ; Synergus 

 melanopus occurs in its gall as an inquiline. — E. A. Fitch. 



26. Cynips galeata, Gir. — The beautiful little gall consists 

 of two parts, one placed upon the other, and tightly drawn
