524 SOME NEW AND LITTLE-KNOWN EXOTIC THYSANOPTERA 



On some Neiv and Little-knowji Exotic Thysanoptera 



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



In the present contribution we have pleasure in describing 

 nine nev/ and interesting species, one of which is the type of a 

 new genus, and in giving further records of five recently 

 described forms. With the exception of Leptothrips flatncornis 

 sp. n., from Madeira, Conipsofhrips albosignatiis (Reut.) from 

 France, .and Docessissophothrips monstrosus sp. n., from New 

 Caledonia, all the species are from the Malay Archipelago. 



The chief material has been taken from a small collection 

 of carded specimens kindly submitted by the Director of the 

 Leyden Museum, Holland, and from a collection made in the 

 Isle of Nias, and very generously presented to the writer by 

 Dr. Karl Jordan. This latter collection, so far as the Malayan 

 material alone is concerned, consists of six tubes containing 

 thousands of specimens, the largest proportion of which 

 are referable to the one species, Zygothrips jordani sp. n., 

 though two other forms, Dinoihrips stimatrensis Bagnall and 

 Ecacanthothrips sangnineiis (Bagnall), are moderately well 

 represented. In addition we are able to describe Dicaiothrips 

 malayensis, D. denticoliis, and Plectrothi'ips coHaris from this 

 collection, and no doubt when the almost countless number 

 of specimens have been examined critically more forms will 

 be discovered. 



Three species from the Leyden Museum, PaJiurothrips 

 gracilis Bagnall, PJdoiothrips similis sp. n., and P. longihibus 

 sp. n., are especially interesting, inasmuch as they bear a 

 strong superficial resemblance to one another, and in addition 

 are found on the same plant, the Waringin tree.

Examination of more recent and better (though by no 

 means perfectly) preserved specimens suggest a few slight 

 amendments of the original description.
