BAGNALL'S THYSANOPTERA 5 



review was begun as a bibliography and catalogue of the type specimens because of 

 the number of slides in his collection bearing manuscript names. As the work 

 progressed it was found necessary to include new synonymy, and so several genera 

 have also been redefined, with keys to the species examined by the present author, 

 and a few species have been redescribed where this appeared to be of particular 

 value. This work could only have been produced through the co-operation of many 

 other Thysanopterists, to all of whom the author would like to express his thanks. 

 Much of the new synonymy published here for the Terebrantia is derived from con- 

 versations with my colleague Edward R. Speyer. Dr. Guv Morison helped with the 

 British species particularly, and during the author's visits to Aberdeen gave valuable 

 advice on field work. Professor H. Priesner, Dr. R. zur Strassen, and particularly 

 Miss Kellie O'Neill have loaned material and given detailed replies to the author's 

 queries in correspondence. Professor S. F. Bailey kindly loaned his manuscript 

 bibliography of Bagnall's Thysanoptera, and specimens were received from the 

 following workers : Professor T. N. Ananthakrishnan ; Dr. J. S. Bhatti ; 

 Professor A. Bournier ; Dr. T. Kono ; Dr. J. Pelikan ; Mr. E. Reed ; Professor 

 L. de Santis ; Dr. L. J. Stannard ; Dr. E. Titschack. With the exception of 

 figure ii, which was drawn by Mr. Arthur Smith, the text-figures were drawn by 

 Mr. B. R. Pitkin. 



BIOGRAPHICAL NOTES 



Richard Siddoway Bagnall was born at Winlaton, near Whickham in the County of 

 Durham, just outside Newcastle on Tyne on the 14th July, 1889 (teste the late F. 

 Laing). According to an obituary notice in The Vasculum (July 1962, p. 11), he was 

 the son of Mr. J. S. Bagnall, a member of the firm of R. S. Bagnall and Sons, forgemen 

 and chainmakers of Swalwell and South Hylton. In unpublished notes dated 1921 

 Bagnall refers to himself as ' Forgemaster and Director of Engineering Works, 

 Rydal Mount, Blaydon on Tyne '. He was educated privately and soon developed 

 an interest in Natural History. In 1903 he was awarded the Hancock Prize for an 

 essay ' An October Day in Gibside ' about the joys of beetle collecting. I have 

 been unable to confirm the statement in the obituary notice published by the Royal 

 Entomological Society of London (Proc. R. enl. Soc. Lond. C, 27 : 50, 1962-63) that 

 he was trained as a chemist, or the title ' Sir Richard ' given to him in the Directory 

 of Zoological Taxonomists, Illinois, 1961. Although an energetic man it appears 

 that his health was never very good, possibly as a result of an attack of meningitis 

 in his youth, and he died on the 19th January, 1962, after a series of cerebral 

 thromboses. 



He was elected a Fellow of the Entomological Society of London in 1904, a Fellow 

 of the Linnean Society of London on the 4th November, 1909, and a Fellow of the 

 Royal Society of Edinburgh in 1920. He was also a member of learned societies in 

 Belgium, France, Italy and Spain. He was one of the honorary curators of the 

 Hancock Museum, Newcastle on Tyne, and also one of the founders of The Vasculum 

 in 1915. In 1929 he was presented by Dr. J. W. Harrison to the University of 

 Durham for the honorary degree of D.Sc, and the University Journal for that year
