PLATE XXXV. 



1, 2, 3. Galls caused by Ctnips tinctoria with ridges and papillae, intro- 

 duced to show how closely they resemble those of C. Kollari {cf. 

 Plate LX, div. B). 



The remainder are English specimens. 

 4, 5, 8, 16. With well-defined ridges and papillae like those on 1, 2, 3. 

 6 to 15. Well-defined papillae only. 

 17, 18. A single style only on each. 

 19, 20, 21. A style and papillae on each. 

 22. Large papillae and ridge. 

 23 to 27. Very large single papillae. 



28. A specimen similar to 27, with papilla pointing towards observer. 

 29 to 33. Coalescent papiEse. 



The point of attachment of each gall to the twig on which it grew, is 

 immediately above the figures, except in 29 to 83, where it is on the right- 

 hand side. 



The specimens have been selected from amongst sevei-al thousands. 

 Unfortvuiately they do not look so remarkable as they really are, partly 

 because they are only two-thirds natiu-al size, and much detail is lost in the 

 photograph.
