able species will rank with the two other great South American 
rarities of this family, P. hahneli, Stgr., and P. hede, Foetterle, 
both of which, I believe, have only been captured but once, and 
remain unique. 
CONCERNING CERTAIN CYNIPID GALLS IN DURHAM, 
NORTHUMBERLAND, AND NORTH YORKSHIRE. 
By J. W. H. Harrison, M.Sc. 
Dunrine the last few years, in collaboration with Mr. R. S. 
Bagnall, I have been working at the more obscure orders in our 
counties, and lately our energies have been directed more par- 
ticularly toward gall-making insects. Our results in Cecidomyid 
and HKriophyid galls have been phenomenal, over a hundred 
species of the Dipterous group and about thirty of the gallmites 
having been added to the British list. In the present class, our 
list of novelties is limited, but it does include one or two. 
Excluding the Oak Cynipids, which are reserved for special treat- 
ment, my list is appended : 
Rhodites rose, L.—Everywhere, seems to prefer roses of the 
Kucanine group; in West Durham, where the Villose are more 
or less dominant, on them also. 
Rhodites mayri, Schl.—This gall is new to Britain, and I 
have only taken it once, on Rosa mollissima m. cuspidatoides, 
Crep., by the road-side between Lanchester and Satley, in 
Durham. It is somewhat like the preceding, which everyone 
knows as the ‘‘ bedeguar,’’ but is softer and lacks the clothing of 
reddish filaments; their place is taken by feeble, ill-developed 
spines. 
Rhodites eqlanterie, Hartig—Common, but varies greatly in 
abundance. Prefers the Villose, but I have seen it on Rosa glauca 
and Rosa canina m. lutetiana, Lem., in the EKucanines, and on 
Tiosa spinosissima mm. pimpinellifolia of the Pimpinellifolie. 
Rhodites rosarum, Giraud.—Rare, prefers the Villose; §. 
Durham, Team Valley, Nunthorpe, Yorkshire. 
Rhodites spinosissime, Gir.—In Durham on Rosa pimpinelli- 
folia. Gall somewhat like the preceding, but embedded as it 
were in the leaf. Occurs chiefly on the coast, but inland at 
West Cornforth. 
Diastrophus rubi, Hartig.—Team Valley, Durham, Nunthorpe, 
Yorkshire. Elongated, slightly irregular swellings on Itubus 
fruticosus. Not common. 
Xestophanes potentille, Retz.—Irregular fused masses on the 
runners and on the roots of Potentilla reptans. Occurs every- 
where with the plant where it grows in light soil. 
Xestophanes brevitarsis, Thomson.—Previously not on record 
for the North of England, found on Tormentilla erecta on Birtley 
Fell in Durham. Gall like the preceding, but not fused.
