swollen, hard, and fleshy, with the sexual organs useless 

 and distorted ; and between the latter live several larvae. 

 I have reared Diplosis Loti De Geer from these galls, 

 which are not rare on sandhills on the Aberdeenshire 

 coast. (T.A.I., 58). 



Lotus major (Greater Bird's-foot Trefoil) bears galls of the 

 same structure as (but more swollen and reddened, and 

 therefore more conspicuous than) those on A. Vulneraria; 

 they also are the work of Diplosis Loti. (T.Sc.N., IV., 

 168 ; T.A.I., 59). I have found them near Aberdeen 

 in August. 



L. COrniculatus (Bird's-foot Trefoil) also has the flower-buds 

 galled, as in the last plant, by D'qilosis Loti. The galls 

 are plentiful near Aberdeen on the Links ; and I have 

 found them at Muchalls and elsewhere in the north-east 

 of Scotland (T.S.N.I., 124, T.A.I., 59); and it is recorded 

 from near Glasgow (B.I., 159). 

 On young branches the terminal bud is galled frequently, and 

 the leaflets and other parts become slightly fleshy and 

 swollen, but remain green. This gall also seems to be 

 the work of D. Loti ; but the insect has not yet been 

 reared from it (T.A.I., 59). 



Astragalus hypoglottis (Purple Milk Vetch), on the Kin- 

 cardineshire and Forfarshire coast, often has the leaflets 

 folded, hard, fleshy, somewhat inflated, and pale green. 

 Usually so many are galled that they form masses one 

 half to one inch or more across. Each leaflet is occu- 

 pied by one or more larvae of a Cecidomyia (POnobrychidis 

 Bremij. (T.S.N., II., 78 j T.A.L, 59). 



Vicia Cracca (Tufted Vetch) and sepium (Bush Vetch) bear 

 galls very like those on A. hypoglottis, except in being 

 rather larger. They are formed by a Cecidomyia. 

 On V. Cracca they have been plentifully found by my- 

 self in Aberdeenshire, Kincardineshire, Forfarshire, and 

 Perthshire (T.S.N.,IL, 78, T.A.,L, 59) ; and they occur 

 near Glasgow (B.I., 159). On V. sepium I have seen 

 them in Aberdeenshire and in Perthshire (T.S.N.I., 124, 

 T.A., L, 59). (Abbe Keiffer, in V. Z. B. Ges. Wieu, 

 1888, pp. 11-12, has described as new a midge under the 

 name C. Vicice which he reared from galls of V. sepium
