from \ to f inch across. In each live several reddish- 

 orange larvae of Lasioptera Rubi Heeg. I have found 

 this gall in September at Dunkeld, but have no other 

 record of it from Scotland. (T.S.N., II., 78.) 



R. fructicosus (Bramble). The leaflets are frequently folded 

 and slightly thickened along the midribs ; and enclose 

 spaces, in which live the orange larvae of C. plicatrix H. 

 L\v. I have found these pseudo-galls at Dunkeld and 

 near Aberdeen, in autumn. (T.A., I., 60.) 



Rosa spinosissima L. Mr. P. Cameron {Trans. N. H. Soc, 

 Glasgow, New Ser., I. p. 297), describes stems of this 

 rose, from the Ayrshire coast, as " distorted and enlarged 

 by what is no doubt a species of Cecidomyia. The 

 swellings vary in length and thickness ; some being 

 nearly two inches long ; others not more than one 

 quarter of an inch ; while in thickness they vary from 

 two to five lines, being as a rule thicker at the ends than 

 in the middle, when their length is over half an inch. 

 When the galls are of some length, they cause the twigs 

 to become bent, and it is very seldom that the swellings 

 themselves are not twisted to a greater or less extent. 

 Internally they are woody, but not very firm in texure; 

 and the larvae do not live in clearly defined cells. The 

 larvae are orange, and of the usual Cecidomyia form. 

 I have unfortunately not been able to rear them to the 

 imago state." These galls are " usually in near proximity 

 to the galls of Rhodites spinosissimce." 



Rosa canina (Dog Rose), and R. villosa have the leaflets 

 very often galled ; they remain folded, and become 

 fleshy, hard, inflated, and red-brown ; and in each lives 

 one white larva (or more) of G Rosarum Hardy (A.N. H., 

 1850, p. 186), (G. Rosa Bremi). These have been re- 

 corded by Mr. Hardy from Berwickshire, and have been 

 found by myself throughout Aberdeenshire and Kin- 

 cardine ; and also in Forfarshire, and at Dunkeld 

 (T.S.N., I., 124, II., 79 b. ; T. A., I., 60); and Mr. 

 Binnie has met with them near Glasgow. (B.I., 160.) 



Crataegus Oxyacantha (Hawthorn), G. Grataegi Winn., often 

 galls the terminal buds of the upper twigs, producing 

 a rosette of sessile deformed leaves, often covered with
