axillary galls on this plant, with the leaves imbricated 

 over them ; the wall is relatively thin and the cavity 

 large. (T.A.,L, 63 b; B.H., 182). Found by me in Aber- 

 deen and Kincardine, and sent me by Dr. Buchanan 

 White from Perthshire, and found by Mr. Binnie near 

 Glasgow. 

 2. Terminal rosettes of leaves -^ to \ inch across and slightly 

 fleshy and purplish, are the work of Cec. galiicola F. Low, 

 the larvoe of which live between the leaves (T.S.N., I., 

 156 ; T. A.., I., 63 a ; T.A., II., 55), common at Banchory, 

 on Deeside, in September. 



G boreale. 



1. Galls of C. Galii on this plant form swellings just above the 



nodes, irregularly ovate, broader below ; the wall is thin 

 and the cavity large. I have found a few examples at 

 Banchory beside the Dee (T.A., I., p. 63, b). 



2. Terminal or axillary leaf-buds, reaching a size of by J inch; 



the leaves are imbricated and green. Each gall is 

 tenanted by one orange larva of a Cecidomyia. Usually 

 several galls occur on astern. They are common in autumn 

 in the valley of the Dee, and Dr. Buchanan White has 

 sent them to me from Perthshire. (T.S.X., L, 156 ; 

 T.A., I., 63 a). 

 G. Aparine (Goose Grass or Gleavers). The galls of C. Galii 



on this plant form masses at the nodes, or at the tips of the 

 stems. At the nodes they include stems and branches in 

 a mass about \ to inch across ; at the tips they form 

 masses as much as \\ inch long by 1 inch across, com- 

 posed of deformed branches, leaves, and flowers. They 

 are always green. Each contains numerous cavities ; 

 each tenanted by a larva. I have found this gall 

 locally plentiful near Aberdeen and at Banchory. 

 (T.S.N, IV, 15 ; T.A., I, 63, 64.) 



G. saxatile (Stone Bedstraw). The flower-buds are swollen 

 considerably, and are occupied by one or more orange 

 larvae of Cecidomyia (Galii ?) which lie among the fleshy 

 inner parts of the flowers. Sparingly found on the links 

 near Aberdeen. (T.S.N, IV, 169 ; T.A, I, 64.) 



Valeriana officinalis (Valerian). The midribs of the leaves 



and the chief veins of the lobes are twisted and thickened;
