our belief in the existence of this law, for there is no rule without 

 an exception. 



Spurge (Euphorbia cyparissias). — The leaflets of terminal shoots, 

 stopped by larva? of Cecidomyia capitigena of Bremi, in their ordained 

 development, produce a bud-like head, beautifully tinged with red 

 (Bremi, loc. cit., tab. 2, fig. 24, p. 25). "Forbach, June, 1867."— 

 W. A. in lilt. July 3, 1867. Cecidomyia subpatula, Bremi, produces 

 a different head of leaflets on the same Euphorbia (Bremi, loc. cit., 

 p. 23, and tab. 2, fig. 25). 



Dyer's Weed (Genista spinosa). — A pod-like gall, about two lines in 

 length, gathered by Mr. Slainton near Cannes, in March, 1867 : insect 

 unknown to me. Ilennie (' Insect Architecture,' p. 331) describes and 

 figures a similar gall on Genista tinctoria, which he refers, with a 

 query, to Cynips Genistas. This latter gall I have never met with. 



Wild Geranium (Geranium sanguineum). — A green leaf-rose, the 

 individual leaflets tinged with red, produced by a Cecidomyia? 

 "AUonby, Cumberland."— W. A. in lill. August 9, 1867. 



Grass. — On a short-jointed, narrow-leafed, low, creeping grass, along 

 a road near Woodside, Croydon, 1 met (in September, 1865) with pink, 

 smooth, polished galls, of the size and shape of a caraway-seed. 

 Dipterous ? 



Hawthorn (Crataegus Oxyacantha). — The bedeguar of the hawthorn 

 was very abundant near Penge in June, 1867. "Was very frequent 

 near Leeds in 1866." — W. A. in lilt. August 9, 1867. Described and 

 figured by Rennie (' Insect Architecture,' pp. 346, 347), who thinks 

 that this excrescence may originate in the natural growth of a shoot 

 being checked by the punctures of Aphides, &c. I should like to see 

 this statement superseded by actual observation. Specimens in my 

 collection show regular rows of buudles of very short brown bristles, 

 set so thickly in some spots as to resemble the fur of some cater- 

 pillar. 



Juniper (Junipeius communis).— A woody hard gall of a little less 

 than walnut size, on the basis of a stem, was sent by Mr. Newman to 

 Mr. Armistead : locality unknown to me. At the Meeting of the 

 Entomological Society of London on the 16'di of March last, Mr. 

 Stainton called attention to the fact that Heir Hartmann, of Munich, 

 had bred a Trochilium, a Grapholitha and a Gelechia, from twigs of 

 juniper, upon which he had observed some gall-like swellings:* an
