338 MOSLEY : ADDITIONAL YORKSHIRE GALLS, 
Lychnidis). Loew thinks them inquilines. P.I.’ I had no 
previous knowledge of a gall on Lychnis, and shall be glad 
to have specimens sent. 
On Populus tremula. Aspen. 
Swellings on the twigs. Caused by a "pestle (Saperda populnea). 
Recorded by Mr. Inchbald, but no locality given. [This is 
observable near Meanwood Hall, in the borough of Leéds 
(W. Denison Roebuck) ]. 
On Prunus spinosa. Blackthorn. 
a of leaf folded under in places, thickened and yellow. 
A number were sent me from Forge Valley, by Mr. T. W. 
Woodhead. Each gall was tenanted by a Cecidomyia (?) 
larva, but I have not yet been-able to ascertain that the gall 
was previously known. 
On Quercus robur. Oak. 
Size of large pea, in axils of leaves covered with bristly projections, 
each with a red papilla at the end. Caused by a cynips 
(Aphilothrix lucida). Mr. A. Clarke gave me three specimens 
of this gall, which, I believe, has not before been recorded as 
British. They were brought to one of the botanical meetings, 
and he thinks they were gathered in Whitley Woods. 
Kidney-shaped galls attached to ribs under leaf. Caused by 
a cynips (Biorhiza renum). Woodsome and Honley Woods. 
On Rosa spinosissima. Spiny Rose. 
Smooth, round, or irregular pea gall, on leaf. Caused by a cynips 
(Rhodites spinosissime). Recorded by Mr. Inchbald, but no 
locality given. 
On Rosa canina. Dog Rose. 
Pea gall with projecting spines, on leaf. Caused by a cynips 
(Rhodites rosarum). 1 have found what I take to be this 
species at Shepley. This ee the four British species of 
Rhodites all found in Yorkshire. But it would be desirable 
to have additional localities. 
On Rubus fruticosus. Bramble. 
‘Swollen bosses, and often pierced, give forth their tenants, 
occasionally a small Nematus. P.I.’ This I take to be the 
gall of Déastrophus rubi. Mr. Inchbald does not give 
a locality. 
On Salix alba. White Willow. 
Edge of leaf rolled down, by a gnat (Cecidomyia clausilia). 
Recorded by Mr. Inchbald. anor
