 which ensued it was stated that many orangs drink their own urine. 

 Mr. Frohawk stated that in dealing with these animals it was

MAY 20th, 1916. 



Field Meeting at Ockham and Wisley. 



Leader.— V^. J. Kaye, F.E.S. 



A Field Meeting Avas held on May 20th to Ockham and Wisley. 

 The morning party left "Waterloo by the 9.20 and arrived at Effing- 

 ham Junction about 10.30, and, from the collecting point of view, 

 all the principal captures were made in the morning. The weather 

 was fine and dry and before lunch a ramble was made in the covers 

 near the station. These consist largely of oak, and the trees, owing 

 to the tremendous denudation of the foliage by the larvfe of chiefly 

 Tortrix viridana and Hibernia defnliaria, presented the appearance of 

 midwinter instead of late spring. In places quite curtains of white 

 silk were to be observed formed by the strands by which these 

 larvfe lowered themselves. The denudation has been noticed all 

 over Surrey and the adjacent parts of Hampshire. It was left to 

 the afternoon party to largely swell the list of the plants observed, 

 and also of the Odonata which were noted at Wisley pond. Tea 

 was to have been taken at the " Black Swan," but owing to 

 structural alterations, at the last minute it was found necessary to 

 go to the " Hut " Hotel on the Portsmouth road. Notwithstanding 

 the short notice of less than three hours a most comfortable and 

 enjoyable tea was provided at 5.30. A long detour was made after 

 the refreshment was over by way of Ockham, the route lying along 

 the Portsmouth Road as far as the " no motors " road on the left, 

 and turning left again in Ockham village. The distance proved 

 longer than anticipated, and some very sharp walking was called 

 for to catch the train. Some elected to come back b\' a later train 

 and to sample the rewards for dusking. The following insects and 

 plants were among those observed during the day : — 



Lepidoptera. — Gonepteryx rhamni, Pieris brassica, P. rapae, P. 

 napi in some numbers, Euchlo'e cardamines a few, Vanessa in, Bren- 

 this eiiphrosijne just coming out, Hesperia malice very common, 

 Nisoniades tatjes, Hypocrita jacobate, Diaphora inendica, Maniestra
