galls in the May or June of the second year. Xenophanes 

 PoTENTiLLA, Villers. 



Rosa canina, L. Stem and leaf. 

 The well-known Bedeguar or 

 Robm's pm-cushion occurs on the 

 stem, and frequently single celled 

 specimens occur as bright red 

 hairy patches on the leaves. The 

 beautiful green and red multi-

locular galls vary much in size -^ 

 and shape, and the desiccated spe- 

 cimens are often conspicuous ob- 

 jects in the hedges in winter. The 

 gall-flies emerge from the galls in 

 spring. Rhodites Ros/E, Linne. 

 (Fig. 6). 



Rosa canina, L. Leaf and leaf- 

 stalk. The smooth, round, pea- 

 sized galls occur generally on the 

 under side of the leaflet, but occa- 

 sionally on the upper side or on 

 the leaf-stalk, and I once found a 

 specimen on the fruit. They are 

 green in colour, reddish when 

 turned to the sun, but later become 

 brown ; their attachment to the 

 leaf is very slight, and when mature 



they fall to the ground at the least touch. The gall-flies 

 emerge in spring. Rhodites Eglanteri^, Hartig. (Fig. 7). 



Rosa canina, L. Leaf. These 

 galls are somewhat similar to the 

 last, but are beset with from three 

 to six spines of unequal length 

 on their surface. They occur on 

 the under side of the leaflet, and 

 generally resemble those of E. Kg- 

 lantericD in situation, size, struc- 

 ture, &c., with the above exception. 

 Rhodites Rosarum, Giraud. (Fig. 8).
