Dracaenura agramma) are recorded from Samoa and Tonga only. The Samoan 

 example of Rivula polynesiana may not be conspeciflc with the Tongan example. 



Six species (Anna tongaensis, Parallelia prisca, Hyblaea sanguined, Bradina 

 acrospila, Margaronia diplocyma, Hydrillodes surata) are recorded from Samoa, 

 Tonga and Fiji. I think it is extremely probable that more material of Anna 

 tongaensis and A. samoensis will show that either there is one variable species 

 common to the three groups of islands or that there are three subspecies. 



Nineteen species are recorded from Samoa and Fiji only, but considering 

 the richness of the fauna in the case of these two groups compared with that of 

 Tonga as we know it, I can only surmise that the apparent poorness of the Tongan 

 fauna is due to the scantiness of the material which has so far come into our hands. 

 Judging from the material received from Fiji by the British Museum through 

 the Imperial Institute of Entomology, it is evident that the fauna of Fiji is 

 much richer than that of either Samoa or Tonga, and still possesses more 

 elements in common with what appears to be the source from which it originated, 

 viz. the Malay Archipelago and New Guinea.
