fauna of Fiji, which is the only other isLand in the Pacific 

 whence any member of the tribe has been recorded. At 

 tlie same time, Anaciceschna jaspidea, Burm., and Diplacadcs 

 trivialis^ Rau)b., both o£ which are well known in Fiji, have 

 never been met with in New Caledonia, although they might 

 have been expected to occur there. 



In addition to New Caledonia, Hc.niicordulia oceanica, 

 Selys, lias been recorded from Tahiti, the Tonga Islands, 

 and doubtfully from New Britain. 



Ischnura heterosticta, Burm., Diplacodes hlpunctuta, 

 Brauer, and D. lueniatodes, Burm., are essentially Australian 

 and Pacific forms. 



Orthi'trum caledunicum, Brauer, Agrionoptera insiynis allo- 

 ycaes, Tillyard, and Rhi/otheuiis ijraphiptera, Hanib., are 

 found elsewhere on the Australian continent or in adjacent 

 islands, while jEschna brevishjUi, Ilamb., is common to New 

 Caledonia, Australia, and New Zealand. 



Ischnura aurora, Brauer, ranges from Ceylon to Tahiti, 

 and Tramea limbata, Desj., in its various forms, from 

 Senegal to Samoa. Finally, Pantala jiavescens, Fabr., has a 

 world-wide distribution.
