Viola canina, L. — Margin of leaf towards base involutely rolled, 

 and becomes fleshy and purplisb-red in colour. Near Milngavie, 

 in September, empty. Mr. Traill (Sc. Nat., I. 124) found dipterous 

 larvse inhabiting the rolls. Perfect insect unknown. 



Lychnis diurna, Sibth. — Calyx slightly inflated at base. A 

 number of larvse live at base of corolla between it and the calyx. 

 Kenmuir Bank, September. Perfect insect unknown. 



Cerastium viscosum, L. — Terminal internodes not developed and 

 leaves become fleshy at base ; each gall contains a number of larvse. 

 Possil Marsh. Perfect insect unknown. Mr. Traill describes 

 similar galls on C. glomeratum. 



Ulex Europmus, L. — Gall formed of the two sepals of flower-bud, 

 inner whorls having disappeared. It becomes very noticeable 

 when the period of flowering has passed, from still retaining the 

 appearance of an unopened flower bud. Each gall contains one 

 larva of Asphondylia Ulicis, Verrall, which passes through its trans- 

 formations within the gall. I have found it commonly at Miln- 

 gavie and on the Kilpatrick Hills. 



Sarothamnus scoparius, Winn. — Axillary, being altered leaf-bud, 

 elongate with toothed apex, throat leading to cell lined with dense 

 white interlocking pubescence. The cell at base thin-walled, and 

 containing one larva oi Asphondylia Sarothamni, Loew., which leaves 

 the gall to undergo its transformations. I have found this gall on 

 the broom wherever I have looked for it, Tollcross, Milngavie, &c. 

 Trifolium repens, L. — Folded leaflet ; one, two, or all of leaflets 

 may be afiected. Each leaflet is inhabited by one larva — the part 

 adjoining mid-rib becoming swollen and fleshy, often tinged with 

 reddish outside. Common at Possil Marsh, New Kilpatrick, &c. 

 Perfect insect unknown. 



Lotus corniculatus, L. — Terminal aborted shoot, forming tuft of 

 leaves, inhabited by a number of larvse. Near Lambhill in 

 August. 



Vicia Cracca, L. — Folded leaflet which becomes fleshy and in 

 time turns reddish in colour. Generally most or all of the leaflets 

 of a leaf are afiected, the whole forming a cluster not unlike that 

 of a mass of flower buds. Near Milngavie, &c., common. It is 

 the work of C. Onobrychidis, Bremi. Mr, Traill describes also 

 similar galls on F. sepium and sylvatica, Lathyrus pratensis, and 

 Astragalus hypoglottis, all probably produced by the same species. 

 Spir(ea ulmaria, L. — Leaf gall, several on each leaf, hemi-
