82 THE ENTOMOLOaiST. 



by Mr. Frver in July, 1916, from Yorkshire, taken on aconite. 

 This is the only record I know of since Van der Goot described 

 the species from Holland on Aconiiiun napellus. It is a very 

 marked species when alate, the head and thorax shiny black, 

 the abdomen clear rich deep green, with black cauda and shiny 

 black cornicles. The antennse are dark and a little longer than 

 the body, the third segment with 45-55 sensoria along its whole 

 length. The cornicles are variable in form, some seem almost 

 cylindrical, others showing RlLopalosiphum form, but never very 

 marked. I have only seen alate females and nymphse from 

 England. 



Two other Aconite species are known, namely. Aphis napelli, 

 Schrank (1801, 'Fn. Boica '), on Aconitum napellus, from Europe, 

 and Karsch's Myziis JLmckianus (1887) on Aconitum cammaruni, 

 Linn., from America. 



FURTHER NOTES ON BRITISH PLANT GALLS. 

 By Harold J. Burkill, M.A., F.R.G.S. 



As stated in the January, 1916, number of the 'Entomologist,* 

 the members of the London Natural History Society have been 

 collecting records of the distribution of British plant galls, and 

 by this method several fresh additions have been made to the 

 lists of British insects and mites. 



Specimens have from time to time been exhibited at the 

 meetings during the past year, and the following notes have 

 been largely compiled from such specimens. Many of them 

 are apparently fresh records for Britain, and of these the most 

 interesting are perhaps those from the Wye Valley region which 

 was visted by six members of the Society during last summer 

 and autumn for short holidays. The total list of galls noticed 

 in that district amounts to over 160 species. 



The following notes have been made from specimens shown 

 at the Society's meetings during the year. The county is given 

 in each case as some guide to the distribution of the galls : 



Clematis vitalba, Linn. — Leaves curled and crumpled by Erio- 

 phyes vitalbce, Can. West Glos. 



Lychnis dioica, Linn. — Gontarinia Steini, Karsch. Bucks. 



Hypericum maculatnm, Crantz. — Perrisia serotina, Winn. W, 

 Glos. and Mon. 



H. montauum, Linn. — P. hyperici, Bremi. Mon. 



Malvn vioschata, Linn. — Leaves galled by Eriophyes gymnoproctus^ 

 NaL, recorded from Bucks in 1915 was found in 1916 near Oxted, 

 Surrey (L. J. Tremayne). 



Tilia platyphyllos Scop. — (i) Firm fleshy swellings showing on 

 both sides of the leaves with a central woody cell containing the 

 yellow larva. When mature this central cell falls out leaving a 

 e^ater-like depression in the fleshy tissue. There may be many
