the abdomen yellow ; two black longitudinal stripes on 

 the last ring of the abdomen. Ovipositor as long as the 

 abdomen ; its first joint dark, the second paler. Length 

 of body of female 2 mm." Dr. F. Loew (V. Z. B. Ges. 

 YVien, 1885, p. 510) records this gall from'Thuringia and 

 Upper and Lower Austria, and Abbe Kieffer found it in 

 Lorraine. Dr. F. Loew has described a similar, but hairy 

 gall on V. tricolor, as made by Cec. Violas F.Lw., but I 

 do not know of midge -galls on this latter Violet from 

 Scotland. 



V. tricolor (Heart's-ease or Wild Pansy) and its sub-species 

 V. arvensis, are said by Winhertz to have the ovaries 

 galled and swollen by Lauxania aenea Meig., a small 

 fly belonging to the family Muscidos. The fly is about 

 -g- inch long ; and is shining, very dark green, with 

 reddish-yellow limbs and wing-veins. The fly has been 

 taken by Dr. Vice near Aberdeen ; but I have no 

 record of galled ovaries on this plant from Scotland. 



Lychnis diurna (Red Campion) has been found by Mr. 

 Binnie (B.I. 159, B.IL, 184-85), near Glasgow, with the 

 base of the calyx inflated, and the flowers remaining like 

 buds. Several larvae live in the calyx, between it and 

 the petals. I have no other record of it from Scotland. 

 It is perhaps the work of C. Lychnidis Heyd. 



Oerastium glomeratum (Mouse-ear Chickweed), often has 

 the terminal bud swollen, with the leaves pressed face 

 to face, and their bases fleshy and concave, enclosing a 

 space, or spaces, tenanted by several orange larvae. 

 These spin up in the galls, to emerge as midges next 

 spring, or occasionally in the autumn in which the galls 

 were formed. They are the work of C. Cerastii Binnie 

 (B.IL, 181-82). The galls are common near Aberdeen, 

 also at Muchalls (T.S.N.IL, 31, T.A., 1, 57), at Perth, 

 and at Possil, near Glasgow (B.I., 159, under Cerastium 

 viscosum). (Abbe Keiffer, I.e. pp. 13-15, has described 

 under the name Cec. Lotharingiae n.sp. a midge reared by 

 him from galls found on C .glomeratum, C.trivicde, and C. 

 arvense, near Bitsch, which agree entirely with the Scotch 

 galls, but the midges differ from Binnie's description of 

 his C. Cerastii in having the body yellow or yellow-
