INSECTS OF SAMOA. 



determinations of the few named species that were recognized from Samoa, 

 where these species could be compared with named material in the British 

 Museum. 



A study of the Miridae serves to strengthen the ideas advanced by Mr. 

 China regarding the origin and distribution of the present hemipterous fauna 

 of Samoa ; namely, it has obviously been derived from the Austro- Oriental 

 sub-region. To facilitate comparison and for the completion of the tables 

 found in pp. 87-88, a table has been worked out showing the world-wide specific 

 distribution of the Samoan genera of Miridae (Table I). 



Specific endemism among the Miridae appears to be even higher than in 

 other families of Hemiptera. Of thirty- three species of Miridae and Antho- 

 coridae known from Samoa, twenty-four species and five genera are described 

 as new. The known distribution of Samoan species is shown in Table II. 



A comparison with the known Miridae of Fiji may be of interest. Kirkaldy 

 (1908) listed ten species of Miridae from Fiji, representing as many different 

 genera. Only four additional species have been recorded since, but no doubt 

 the small number of Miridae known from Fiji is due to lack of attention in 

 collecting these forms. Of fourteen species of Miridae recorded from the Fiji 

 Islands, only four are recognized among the Samoan material. These species 

 are : Creontiades "pacificus (Stal), Nesodaphne knowlesi Kirk., Felisacus filicicola 

 (Kirk.), and Cyrtorhinus riveti Cheesman.
