Introduction 



The area dealt with in this paper includes Samoa, Tonga, the Ellice and Tokelau 

 Islands, and Swain's Island. The collection on which it is mainly based was 

 made by Dr. P. A. Buxton and myself during two years (1924 and 1925) spent 

 in Samoa while employed in research work on Filariasis for the London School 

 of Hygiene and Tropical Medicine. During the course of our work we visited 

 all the islands of Western Samoa, and in addition were able to do a little col- 

 lecting in Tutuila (American Samoa) on several occasions. I have also been 

 greatly helped by records and specimens from Dr. J. S. Armstrong and Dr. A. J. 

 Brass ; such records, together with all others not my own, are given below 

 with the recorder's name appended. Most of the Tongan records were obtained 

 during a visit I made to the group during February and March, 1925.* I was 

 in Togatabuf from 14th to 26th February, in Haapai on the 13th and 27th, 

 and in Vavau on the 12th February and from the 28th February to the 

 13th March ; unfortunately a large number of the specimens collected by me 

 in Tonga were destroyed on the way to England. I also owe to Dr. Armstrong 

 a number of Tongan specimens which he collected in the same localities in 



* This visit, and one of about a week's duration to American Samoa, were made possible 

 by a grant from the Fund for Promoting the Study of Evolution, presented to the University of 

 Oxford by Prof. J. M. Baldwin, and administered by Prof. E. B. Poulton, F.R.S.
