Of the forty-eight existing Heteropterous families, only twenty (including 

 Miridae) have so far been recorded from Fiji and Samoa, but these include all 

 the more important groups. The apparent absence of the Gelastocoridae, 

 Notonectidae and Cimicidae from Fiji, and of the Anthocoridae, Henicocephalidae 

 and Colobathristidae from Samoa, will no doubt be disproved by further col- 

 lecting, although it is possible that the last two families may actually be absent 

 from Samoa. The apparent absence of the Corixidae from both faunae is 

 remarkable, and it is interesting to recall that this family is also represented by 

 only two species in New Zealand, where, according to Dr. J. G. Myers, suitable 

 aquatic conditions are not abundant.
