NOTES ON SOME CrKNERA AND SPECIES OF THYSANOPTERA 

 NEW TO THE BRITISH FAUNA. 



BY RICHARD S. BAQNALL, F.E.S. 



Very little attention has been given to the Thysanoptera by 

 British Naturalists since Haliday's papers* on the subject were pub- 

 lished more than half a century ago, though it is an Order of more 

 than usual economic interest. An excellent Monograph of them 

 has been written by Prof. Uzel and of the species which he recog- 

 nises no less than one hundred are from his own country, Bohemia. 

 Prof. 0. M. Eeuter, of Helsingfors, has also added much to our 

 knowledge of the Thysanoptera, whilst more recently Mr. W. B. Hinds 

 has contributed a paper towards a Monograph of the North American 

 forms. f 



During my spare moments, unfortunately much limited, I have 

 this year collected a large number of Thrips of which more than 

 one half yet await identification, but of those named with reason- 

 able certainty many are of special interest, and in a paper to be 

 published shortly by the Natural History Society of Northumberland, 

 Durham and Newcastle-on-Tyne, an account of these creatures will 

 be given. The following species are now worthy of note, as, with the 

 exception of Liothrips setlnodis, Reut., and Aptinothrips nitldida, 

 Hal., all are, so far as I am aware, new to the fauna of Great 

 Britain, whilst representatives of the genera Meyalothrips, TTzel, 

 Uzeliella, mihi, Oxyothrips, Uzel, and Parthenothrips, Uzel, were 

 previously unknown as British.
