14 Brown : Some Derbyshire Plant Galls. 



shortened so that the young shoot takes the form of an ovoid 

 cluster of leaves forming a gall, and containing whitish larvae. 

 This gall, which occurred in large numbers on small specimens 

 of the plant at Ashford-in-the-Water, corresponds well with the 

 description given by Houard {op. cit. p. 620, No. 3617) for C. 

 barbichei. 



Perrisia gain H. Low. On Galium veriim L. Plentiful. Lathkil Dale. 



Perrisia kiefferiana Riibs. On Epilobium angustifolium L. Causing 

 the leaf-margins to be rolled under, the rolls containing a white 

 grub. Lathkil Dale. (See also Brown, T/je A^a/j<;'fif/ts<, February, 

 1920, p. 73.) 



Perrisia a ffinis Kiefi. On Viola canina'L. Leaf -margins rolled upwards, 

 thickened, coloured greenish-violet, the rolls containing either 

 white grubs or pupae. Apparently very scarce. Via Oellia.

P. lathvricola Riibs. On Lathyrus pratensis L. Stipules of the upper 

 leaves swollen and thickened, enclosing the young leaves, and 

 the reddish grubs. Swanton [op. cit., p. 214) describes this g3.U 

 as consisting of the leaf folded pod-wise, with swollen mid-rib 

 forming a keel ; but in all the galls observed by me, it was the 

 stipules that were especially swollen and enclosed the larvae 

 (as also Houard, p. 642, No. 3771). Fairly plentiful. Bakewell.

 E. gain Karp. On leaves of Galium saxatile L. The mites contained 



within the rolls of the leaves probably belong to this species,
