FIELD MEETINGS FOR I9II 347 



meeting Chirothrips hamatus Trybom, Frankliniella tenuicomis 

 Uzel, Bagnallia klapaleki Uzel, and B. dilatatus Uzel, were 

 discovered, all new to the British fauna. 



Altogether the year has been an extraordinarily fruitful one, 

 for it must be remembered that these records are merely the 

 results of very limited spare-time collecting and study. The 

 additions to the British fauna may be summarised as follows : 

 one order, four families, eight genera, and about sixty species, 

 of which thirteen or fourteen are new to science. 



In the following text or lists a single or double asterisk 

 denotes an addition to the counties' or British fauna 

 respectively. 



The Derwent Valley, Saturday, May 13TH, 1911. 



A beautiful day in May saw the opening meeting of the 

 summer session, when well over a hundred members of our 

 Society, the Vale of Derwent Naturalists' Field Club and the 

 Gateshead Teachers' Natural History Society met together at 

 Swalwell. Mr. Adamson, whose intimate local knowledge 

 was kindly placed at the disposal of the party, led the way to 

 Winlaton Mill, where the Derwent was crossed by the Butterfly 

 Bridge and skirted on the south side to the viaduct. Here 

 the parties divided ; some, entering Gibside, spent a pleasant 

 hour in Snipes' Dene, whilst others wandered through the 

 Hollinside fields to the ruins of Hollinside Manor House, 

 where a splendid vista was obtained, including as it did the 

 beautiful Gibside Woods (now clothed in the varied and tender 

 shades of Spring) and the bold outstanding scars. Throughout 

 the afternoon the cuckoo was heard, now on the north bank, 

 now on the south ; swallows were seen skimming the air, and 

 a pair of swifts, which build annually in the Hollinside ruins, 

 were watched with interest. 



Several ornithologists, botanists, and entomologists were 

 present, whilst geology, archaeology and photography each 

 had its devotees.
