HEMIPTEEA— HETEROPTBRA. 



87 



family is extraordinarily well represented in Fiji and Samoa by no less than 

 ten species is very suggestive. 



The following table showing the world-wide specific distribution of the 

 Samoan genera will give some idea of the relationships of the Samoan fauna. 

 It should be remembered, however, that our knowledge of the distribution of 

 the Heteroptera is still fragmentary, and that the region in which a genus reaches 

 its greatest development is not necessarily the place of origin. Generally 

 speaking, the table clearly shows that the Samoan fauna is most closely related 

 to that of the Austro-Oriental subregion, and has obviously been derived from it. 



The numbers of Polynesian species are printed in heavy type for easy 

 comparison.
