more oval cells, each about 34; inch long, surrounded by a compact 
cell wall, outside which is a thicker layer of looser and somewhat 
fibrous tissue. Each cell is inhabited by a larva of Zenophanes 
Potentille, Vill. Dr. Vice gave me a specimen, found by him on 
Brimond Hill. 
Rosa spinosissima L. (= Scotch Rose) A., Galls of Rhodites spinosissime, 
Gir.—There are several chief varieties. Var. a., the simplest form, 
is around gall, about } inch diameter, situated on a leaflet pro- 
jecting above and below, smooth, and bright red above; each 
contains a single central cell, closely surrounded by a broader 
layer of looser, but woody tissue. Sometimes the whole leaflet is 
so altered that only a narrow dentated fringe remains to indicate 
the margin. Var. } is the same as Var. a, save in being larger, 
more irregular in form, and containing several cells. Var. c is 
situated on the young twigs, and may contain one or more cells. 
Var. d is situated on the calyx of the fruit, from which it projects 
as a roundish or obovate body, $-4 inch in diameter, and contain- 
ing one or more cells. Each cell contains one larva. The galls 
are very conspicuous, and may be found from August to October 
on the bushes, or during the winter and spring on the ground. 
They occur on Murear Links, at Muchalls, at Banchory, from 
Ballater to Balmoral, &c, Mayr states (Die Europ. Cynipiden- 
Gallen, p. 16), that these galls also oocur on Rosa canina L., but 
I have never found them on this species. 
B. These galls are globular, about 4 inch diameter, smooth, bright red, 
and contain a pretty large cell, tenanted by one larva of Rhodites 
(Eglanterie, Hart.?) They are attached to the upper side of the 
leaflets by a narrow base. They occur rather sparingly on Mur- 
car Links, at Banchory, Abergeldie, &c.

are identical, I shall describe 
them together. 
Galls of Rhodites Eglanterie, Hart. Externally like 3B. on Rosa 
spinosissima, but sometimes a few bear bristles, and are sometimes 
dark-green in colour; the walls are very thin, and yield to pressure. 
These galls are common wherever the plants grow. Sometimes 
they are attacked by inquilines when they increase in size, become 
somewhat flattened and irregular in shape, and their walls become 
hard, thick, and irregular, and enclose several cells, while the 
central cavity becomes very small. This abnormality was de- 
scribed by meas possibly distinct in the Scot. Nat., I., 125 (c). 
(‘Bedeguar’) Galls of Rhodites Rose L. They are situated on 
the midribs of the leaflets, on the petioles, or on the branches; in 
the former situations they are usually one-celled, in the latter 
they form masses } to 14 inches in diameter. They are covered 
externally with long, mossy-looking branched green, yellow, or 
red filaments, soft when young, but afterwards stiff and erect. 
They consist of a rather hard, woody tissue, amidst which are 
situated one or more (often many) cells, each occupied by one 
larva. They are much infested by parasites and inquilines. 
These galls are sometimes abundant where they occur, as at 
Muchalls, Stonehaven, Banchory, Alford, &c. 
Galls of Cecidomyia Rose, Bremi. They are like those of C. 
Trifolit on Trifolium repens in origin, aud much the same in ap- 
pearance, but the inflated part is reddish-brown. Each contains 
one (or more) white larva. They are common at Muchalls, at 
Banchory, in Strathdon, above Ballater, &c.
