NEW GENERA AND SPECIES OF T-HYSANOPTERA 1 83 



On some New Geneva and Species of Thysanoptera 



By Richard S. Bagnall, F.E.S. 



(Plates VI. and VII.) 



Although the Thysanoptera of Europe and North America 

 have received special attention by Continental and American 

 entomologists during the past fifteen years or more, the species 

 of other countries and continents are almost entirely unknown. 

 The order is a very interesting one, however, and is now 

 beginning to attract the serious attention of several naturalists, 

 so that our knowledge of the subject will, undoubtedly, be 

 greatly increased during the next few years. 



The present short contribution is one of many preliminary 

 papers which I am at the present preparing, hoping when 

 the Order has been reduced to a working basis to compile the 

 volume on the Thysanoptera of the world for Wytsman's 

 Genera Insectornni. I have thought it preferable to base this 

 paper upon certain peculiar and, with few exceptions, large 

 and strongly characterized species, the material of which I 

 have drawn from collections and specimens kindly submitted 

 to me by Mr. C. O. Waterhouse, British Museum; Professor 

 Bouvier, Paris Museum ; Mr. G. C. Champion (ex coll. Messrs. 

 Godman and Salvin) ; Professor J. C. H. de Meyere, Amsterdam 

 Museum, and Dr. H. Schouteden of Brussels. With the 

 exception of the two very interesting species sent by Prof, de 

 Meyere {Machafothrzps biuncinata gen. et. sp. nov., and 

 Dinothrips sitniatrensis gen. et sp. nov.) all the specimens are 

 unfortunately dried and carded, and are thus difficult to 

 describe with satisfaction. I am also painfully aware of the 

 many imperfections of my work and descriptions, and can 

 only express regret that the time I am able to devote to the 

 study of these interesting little insects is so very limited. For 

 two reasons I have thought it desirable to hasten publication, 

 firstly to draw the attention of other entomologists, both at 

 home and abroad, to a most interesting but sadly neglected
