Viola canina (Dog Violet). 



*V. sylvatica Reichenbachiana. 



On both these plants, and especially on the latter, the 

 hinder lobes of the leaves are often rolled upwards, 

 and become very fleshy, much thickened, and purple in 

 colour. Often many galls occur in a rosette-like ar- 

 rangement on a plant, rendering it stunted. Common 

 on the Links near Aberdeen, and also in Strathdon 

 (T.S.N., I., 134, and T.A., I., 57), and near Glasgow 

 (B.I., 159). I have also found it at Rannoch. 

 In 1886, the Abbe Kieffer reared female midges from galls on 

 V. sylvatica (sub nom. V. sylvestris Lnk.), evidently of 

 the same kind as those described above, and found that 

 they belonged to a species not previously known, which 

 he named Cecidomyia affinis. He describes the female 

 thus : " Head pale yellow, with a yellow tuft of hairs in 

 the middle of the pale-coloured face. Hinder part of 

 the head brownish ; eyes black ; proboscis and palpi pale 

 yellow. Antennae as long as the head and thorax to- 

 gether, brown, joints 2 and 13 ; the latter joints cylin- 

 drical, unstalked, each with two small rings of hairs, of 

 which the anterior runs obliquely round the middle, and 

 the hinder, the hairs of which are shorter, is near the 

 base, and almost adpressed. Thorax slate-gray, yellow 

 below ; scutellum yellowish. Wings clouded ; the first 

 longitudinal vein not very distinct, as it is close to the 

 front margin and passes gradually into the latter beyond 

 its middle ; the second longitudinal vein bends a little 

 downwards in its apical half and reaches the margin in 

 front of the tip ; the third longitudinal vein bifurcates in 

 the middle of the wing ; its anterior branch reaches the 

 hind margin as far behind the tip of the wing as the 

 second vein does in front, and the posterior branch 

 runs vertically to the hind margin ; there is no distinct 

 cross-vein. Halteres yellow. Legs pale, with a brownish 

 shimmer. Abdomen orange, with broad cross-belts 

 above, composed of dark scale-hairs ; the other hairs on
