lane at Wimbledon Purk. An annual herb, native of Siberia, it is- 

 of rare occurrence in this country, and is set down by Hooker as an 

 escape from gardens. It is, however, difficult to suppose that a 

 plant with such small flowers in proportion to its large leaves, with 

 no economic value, would have been introduced deliberately into 

 gardens. Loudon gives the year of its introduction as 1820, so this 

 is its centenary. 



Mr. Withycombe exhibited an immature form of the Homopteron 

 Ledra aurita, beaten from oak. 



Mr. Main exhibited sycamore leaves showing tracks of the larva 

 of the saw-fly, Pliyllotoma acerix, and referred to the difficulty in 

 breeding these insects. 



Mr. Tonge remarked that he had been told by Mr. Coppeard that 

 Micro-Lepidoptera were easily bred if enclosed with their food in 

 paper bags placed on the damp floor of a disused greenhouse, and 

 suggested that possibly other orders of insects could be so bred out 

 successfully. 



JUNE Uth, 1920. 



Field Meeting — Horsley. 



Conducted bij Stanley Edwards and Hy. J. Turner. 



This was a whole day field-meeting and about a dozen members 

 were present. The route taken was by the footpath near the rail- 

 way, through the fields of West Horsley Place to the church, and 

 thence by the path for the sheep leas and Netley Heath, returning 

 by the chalk lane to the " Duke of Wellington " Hotel for tea. 



The morning was somewhat threatening, but although thunder 

 and rain seemed to be present all around the party were in no way 

 inconvenienced until the mid-afternoon, when the immunity of the 

 morning was broken and the storm passed immediately over, and 

 most of the party being more rather than less unprotected got fairly 

 wet through. However, all arrived safely at the tea, and did such 

 ample justice to the fare there provided that the proprietress 

 insisted upon an increase in the charge for our meal. 



The ground has been visited by the Society on numerous 

 previous occasions, of which reports have already appeared, so that 

 no detailed list of captures has been appended. Most of those 

 present were quite satisfied with the results of the day's collecting, 

 although nothing not previously recorded turned up.
