Report of the Field Meeting- held at Leith Hill, 

 June 30th, 1906. 



By Edward Step, F.L.S. Read January lot/i, 1907. 



As this was an experimental whole-day meeting only a small 

 attendance was looked for, but a party of eight fully enjoyed the 

 walk from Holmwood via Anstiebury and Coldharbour Common to 

 the summit of Leith Hill, and thence to Dorking through miles of 

 heather, bilberry, and pine-woods, by way of Broadmoor, Squire's 

 Great Wood, and Bury Hill. The weather was delightful throughout 

 the day. 



Again I am chiefly dependent upon Mr. H. J. Turner for a list 

 of the insects captured or observed. He writes : " Two species of 

 Lepidoptera, which previously I had not met with, were somewhat 

 common, so I devoted most of my time to them, and thus did not 

 make a very long or varied list of captures. Bomolocha fontis* 

 (crassalis) was in some numbers, but most difficult to capture, and 

 when captured it was found to be extremely restless in the boxes. 

 The best place was on a steep slope under the trees among waist- 

 high heather and bilberry ; in almost every instance the insects rose 

 high above one's head before they could be reached. The other 

 species, Tortrix viburuana, was flying rapidly over the heather, and 

 the pupa-cases could be found sticking out from the bunches of 

 tied-together leaves of Viburnum opulus. Other species which I 

 either saw or took were : Bupalus piniaria, Thera variata, Melanippe 

 sociata, Camptogramma bilineata, Acidalia aversata, Eupithecia 

 laria'ata,* and Melanippe procellata among the Geometers. The 

 Pyrales were represented by Pyralis costalis (fimbrialis) and Ebulea 

 sambucalis ; the Deltoides by Zandognatha grisealis ; the Phycidas 

 by Pempelia palumbella ; and the Tortrices by Tortrix forsterana 

 and Eupcecilia angustanaP. Olindia ulmana was also taken, but not 

 commonly, by Mr. South. 



Mr. Tongeadds to the list Lithosia mesomella, Cucullia umbratica* 

 Boarmia repandata, B. consortaria, Macaria liturata, Acidalia 

 remutaria, Melanippe unangulata, Cidaria picata, Aplecta nebulosa* 

 Larentia pectinitaria* Those marked * were photographed in situ 

 by Messrs. Tonge and Step.
