Records of some New British Plant-galls. IV. More New Ceci- 
domyid Galls. 
By RICHARD S. BAGNALL, F.L.S., F.H.S., and J. W. H. HARRISON, M.Sc. 
(Continued from page:203.) 
The following records are chiefly of September captures, though 
some are the residue of earlier collecting, whilst three names are given 
of galls previously recorded without name. In one or two cases, such 
as in Perrisia praticola, we have discovered old galls without the larve, 
but hope to remedy such cases next year. 
[Trotteria galii, Ribs. (= Houard, no. 5,290)]. 
This is the Cecidomyid no. 5,290 of Houard, which we recorded in 
our last notes (Hnt. Rec., 1916, p. 203) from Lancashire. 
|Antichira striata, Ribs.]. 
This is the Cecidomyid sp. recorded by us from leaf-sheaths of 
bulrushes (/.c., p. 208), which is known on the continent from the 
sheathing leaves of grasses, sedges, and the like if they are coarse and 
large.
