Occurence of Coenoneura Dahlhomi, Thorn!)., a genus and species: of Tcniliredi- 

 nidce new to Britain. — On the 30tli of June, in Cadcler Wood, near Glasgow, I 

 liad the pleasure of taking a single specimen of Coenoneura DaJtlbomi, Thorns., 

 (Hjmen. Scand., i, 182 ; Opusc, i, 271), a genus and species of Tenthredinida new 

 to this country. The genus Coenoneura may be readily recognized from Fenusa and 

 Fenella, the genera between which it is placed, by its 7 or 8 jointed antennae, and 

 by the two marginal and four sub-marginal cells in the anterior wings. My specimen 

 is the variety described by Tliomson, and has the antennre entirely black, and 

 apparently 7-jointed, but with a strong lens they appear to have in reality eight 

 joints. It was beaten out of birch, along with Fhyllotoma nemorcda, Fallon, and 

 P. microcephala, Klug, two allied species ; and nothing appears to be known 

 regarding the larva, although no doubt it is a leaf-miner. On the 9th of August, 

 I saw in the same locality, what appeared to be another specimen, but having at the 

 moment both hands occupied, failed to secure it. — Id. 



Occurrence of the galls of Cgnips ferruginea, Hartig. — Last week, when collect- 

 ing in Gadder Wood, I was compelled by the rain to take shelter under an oak, and 

 succeeded in discovering on the leaf-buds, several of the galls of Cynips ferruginea, 

 Hartig (Germ., Zeits. Ent. 2, 189). They are of a woody texture, somewhat spindle- 

 shaped, and covered with short, brownish wool. C. ferruginealifisnot been hitherto 

 recorded as British. — Id. : August 15th, 1873. 



OaJcgalls at Ballater, in June, including Andricus amenti, Giraud, new to 

 Britain. — On June 14th, with my fi-ieud Mr. Vice, I went to Eallater for a 

 day's collecting, especially to look for oakgalls, and was successful iii finding abundance 

 of galls of Andricus quadrilineatus, of Andricus ramuli, L., and (on one bush) of 

 Andricus inflator, not to mention more common kinds. On afterwards looking over 

 some catkins bearing galls of quadrilineatus, which we had brought back with us, 

 we found abundance of galls of Andricus amenti, Gir., which have smce produced 

 the insect. They are very small and inconspicuoiis, sessile, ovate, attached by the 

 rounded end, not exceeding J^'i^ch in length, covered with short hairs, and, when 

 mature, of a brown colour. 



Galls of Andricus quadrilineatus, Hartig, as above mentioned, occur at Ballater, 

 and I have found them commonly near Aberdeen, so they are quite common in this 

 district. In addition to my previous note on these species, I may mention that I 

 have found them frequently on leaves, attached to one side of the midrib, and differ- 

 ing in no respect from those on the catkins, the colour being indifferently in both 

 green or reddish-brown. Wlien they occur on the midrib, the lamina is deficient 

 opposite the point of attachment. This variety of the gall is clearly the same as 

 Schlechtendal's species (described simply from galls), Cyni-ps marginalis (?), and is 

 clearly specifically identical with the more usual forms on the catkins. — James W. 

 H. Teaill, Old Aberdeen : July, 1873. 



Occurrence of galls of Spathegaster vesicatrix, Schlechtendal, at Banchory. — 

 On Saturday, July 5th, I found the galls of this insect abundant in oak leaves, at 

 Banchory. As I am not aware of any English description of them, I will now
