214 The Scottish Naturalist 



VACCINIUM VITIS-IDAEA L. :— 



I formerly described briefly (Se. Nat., i., 158) galls on this plant 

 found by me in Braemar ; but could offer no conjecture as to the 

 maker, as the galls had been lost. In the autumn of 1882 I again 

 have found these galls in Braemar ; and have found in each a 

 few yellow larvae of a Cecidomyia between the involute imbricate 

 red fleshy leaves of the terminal buds. 



Mr. Cameron describes (E.M.M., xii., 190) a Saw-fly, Nematus 

 erassipes var. Vacriniellus Cam. reared by himself from galls on 

 V. Vitis-Idaea, but does not describe the gall, which I have not 

 myself met with. 

 GENTIANA CAMPESTRIS L. :— 



In August 1882 I found, in Braemar, two plants of this species 

 bearing flowers tenanted by small pale yellow larvae of a Cecido- 

 myia. Some of the flowers were abnormal in having buds growing 

 in the axils of the petals and from the centre of the ovary ; but 

 the larvae also were present in other buds which differed from the 

 normal condition only in having the parts of the flower slightly 

 swollen and fleshy, with the sexual organs ill developed. Larvae 

 were numerous inside the ovaries, the seeds in which were quite 

 abortive or else ill developed ; and they also were present in 

 small numbers between the other parts of the flowers. Dr. 

 Dickie has described {Edinb. Bot. Soc. Trans, ii., pp. 192-196) 

 abnormal flower-buds like the above from near Aberdeen ; but 

 he makes no mention of the presence of larvae in these found 

 by him. 

 PLANTAGO LANCEOLATA L. :— 



a. Galls of Mecinus py raster Herbst (Se. Nat. ii., p. 252, and 

 iv.j p. 16), oval swellings of the scape near the top, less often of 

 the petiole. These weevil-galls are not rare in a good many 

 places in the North-east of Scotland. 



b. Galls of one of the Anguillulidce (? Tylenchus sp.), so similar in 

 structure to those just to be described on P. maritima that it is 

 needless to describe them on both plants. They are of larger 

 size on P. laneeolata, occasionally almost extending from edge 

 to edge of a leaf; and are less markedly different in colour 

 from the rest of the leaf, than they are in P. maritima. I have 

 found these galls in one or two localities near Aberdeen, from 

 May till October ; also at Banchory Ternan on Deeside, and at 

 Rescobie in Forfarshire. 



PLANTAGO MARITIMA L. :— 



Galls of Tylenchus {? sp. it.) in the leaves and leaf-stalks, seldom
