is interesting, apart from entomology, for a dew pond and remains 

 of dwellings of a neolithic race of man. The afternoon did not 

 result in any lepidoptera being captured worthy of record except a 

 nice variety of liitmicia phUras, taken by Mr. H. Moore, in which 

 the usual markings of the forewings were replaced by lines. Two- 

 of the party diverged to a distant clover field for t'olias ediisa, but 

 were not fortunate enough to see it. Several bright yellow butter- 

 flies, however, they were assured by a farm labourer, had been there 

 earlier in the day. A pleasant stroll back through Slines Oak 

 Wood, and along the slopes of the downs, brought the party back 

 to Warlingham, where they were hospitably entertained by Mr. 

 Smith at his residence. 



SEPTEMBER 25th, 1913, 



Exhibition of Lantern-slides. 



Mr. C. B. Williams exhibited a lantern-slide of an adult male 

 Embiid, species unknown, bred from a larva collected by Mr. 

 Buxton in iVlgeria. 



Mr. Dennis exhibited slides of flower-groups in their natural 

 surroundings, of a field of fuller's teasel, and of the shed where the 

 cut-plants were hung up to dry on poles. 



Mr. Main exhibited slides of a larch sawfly {Nematiis ericJisoni), 

 and described the details of the life-history of the species, which 

 was the cause of much damage in the woods near Manchester. 

 The cocoons were made in the ground under the trees and were no 

 doubt preyed upon considerably by mice and voles, while birds 

 helped to keep the pest in check by eating the larvje. At present 

 little had been done to control them by parasites, but an attempt is 

 being made to introduce them. The eggs were laid at the ends 

 of the shoots between the needles by the females, which were 

 mostly parthenogenetic. The males were extremely rare. The 

 twigs attacked assumed gradually a curved shape, and extensive 

 defoliation was frequently caused. The larvae spun cocoons and 

 rested thus throughout the winter, not turning to pupte until the 

 spring. 



Mr. C. W. Colthrup exhibited lantern-slides of the eggs and nests 

 of seabirds. 



Mr. Carr exhibited photographs, taken by Mr. Step, of the large 

 spider, Epeira quadrata, exhibited by Mr. Carr at the previous 

 meeting. 



Mr. W. J. Lucas exhibited speciiiiens of the grasshopper
