57 
inch long, light grayish green, the undersides of its component 
leaves being exposed. Between the leaves among the hairs lie 
one or more of the larve. The galls are common at Muchalls, in 
Glengairn, near Balmoral, in Strathdon, &c. 
Nat. Orp. VIOLACER. 
‘Viola canina L. subsp. 
One or both lobes of the hind margin are rolled up, and become 
hard, fleshy, and smooth, and usually purple in colour. Each 
roll is occupied by one (rarely more) larva of Cecidomyia = 
I have not succeeded in rearing the insect. The galls are abun- 
dant on Old Aberdeen and Murcar Links, and I have also found 
them in Strathdon. 
Nat. Ord. CARYOPHYLLACE. 
Cerastium glomeratum Thuill. Apical, the basal half of the terminal 
leaves becomes hard, swollen, and fleshy, and yellowish-red in 
colour; they enclose a central cavity in which live several orange- 
coloured larve: of a Cecidomyia. The larve spin small white cocoons 
in which they pass the winter as pupw ; I have not succeeded in 
rearing the insect. The galls are abundant near Old Aberdeen, 
at Rubislaw, and at Torry near Aberdeen, and at Muchalls. 
They are not conspicuous. Mr. Binnie has reared the insect from 
galls found on C. glomeratum (= C. viscosum L.) at Glasgow, and 
has named it Cec. Cerastit (Proc. of Nat. Hist. Soc. of Glasgow, 
Vol. IIL., part II., 1877). 
Stellaria media L (= Chickweed). Mr, Sim tells me that he found galls 
on this plant near Stonehaven some years ago; he described them 
as being round, smooth, green, about half the size of a pea, and 
situated about 4 of the distance from the end of the stem. I 
have never seen galls on this plant, and should be much obliged 
for specimens. 
Stellaria Holostea, L (= Greater Stitchwort). Apical, the terminal leaves 
becoming hard, somewhat swollen, semi-conduplicate, and closely 
imbricate ; they also become yellowish green in colour, and are 
readily deteeted. Between the leaves live a good many indivi- 
duals of Aphis. .The galls are common near Old Aberdeen and at 
Muchalls. ~ 
Nat. OrnD. HYPERICINES. 
Hypericum pulchrum L. (= St. John’s Wort), terminal or axillary, 
reaching a size of $ x 38; inch. The basal = of the leaves are 
swollen, inflated, fleshy, red, and smooth, with the midrib pro- 
minent. Between the leaves live several orange larve of Cecidom- 
yia serotina; Winnertz? These galls were found in Braemar by 
Dr. White who sent me specimens. 
Nat. OrpD. GERANIACER. 
Geranium sanguineum L. (= Bloody Cranesbill) terminal, forming very 
conspicuous masses + to 1 inch in diameter composed of the 
altered leaves; the segments become thickened, and fleshy, and 
the margin’s becoming revolute they form irregular tubes nearly 
smooth externally and green or yellowish with their tips deep red ; 
internally the tubes are loosely filled with white hairs among 
which live multitudes of a pale green mite, Phytoptus Geranit, The 
galls are common at Muchalls and elsewhere on the Kincardineshire 
coast, in July and August.
