356 Mr. R. S. Bagnall on some 



curious as the first three herein described, two of which are 

 giants of their order, one feels that there is also a considerable 

 historical interest in connexion with this collection, associated 

 not only with a naturalist of world-wide fame, but with that 

 portion of the Eastern Hemisphere whereon is ba?ed one of 

 his most widely read works, the ' Malay Archipelago.' It is 

 therefore a pleasure to me to have this opportunity of 

 naming one of the most important species in this small but 

 valuable collection in Dr. Wallace's honour. 



I would also exjDress my gratitude to Mr. C. O. 

 Waterhouse for the kindly help rendered me in examining 

 the collections of Thysanoptera belonging to the British 

 Museum. 



Order THYSANOPTERA. 

 Suborder TuBULiFERA, Haliday. 



A knowledge of the species of the suborder Tubulifera 

 outside Europe leads one to believe that it might with advan- 

 tage be divided into two families, Phlceothripidas and Idolo- 

 thripidffi, the characters given by Haliday for his two genera, 

 Phloeothrips and Idolothips, being in themselves sufficient to 

 warrant such a division. 



Ocelli tres sequidistantes, in alatis saltern : hau- 



Btellum inter coxas anticas subdeflexum : 



palpi labiales ovati : alse anticse vena unica 



nonnisi inchoata(vel abbreviatae aut nullje). 



[Caput oblongum, depressum : abdomen [Uzel.

Ocellus anterior remotus ab basi antennarum : 



baustellum basin prosterni attingens :

vena uuica obsoletiore dimidiata, aut abbre-

men excavatum,] Fam. Idolothripidae, 



The Phlceothripidse contains several genera already well 

 known, whilst the Idolothripidse will contain the genus 

 Idulothrips (s. s.), Haliday (type species 1. marginata, 

 Haliday, 1852), and other allied genera which it will be 

 necessary to establish for the reception of certain species now 

 in my hands. 



Family Idolothripidae, mihi. 

 Genus Mecynotheips *, nov. 

 Head more or less cylindrical, three times as lonf as 

 * iIfecy«o= prolonged.
