XV. The Hymenoptera of Fiji. By Rowland E. Turner,

[Read November 20th, 1918.] 



Only fifty-three Hymenoptera seem so far to have been 

 recorded from Fiji, including five new species described 

 here. Of these several are undoubtedly introduced 

 species, and others are known to have a wide range in 

 Polynesia. A few of the larger species are almost certainly 

 confined to Fiji, and show no near relationship to species 

 found in any other group of islands. Thus Cyphononyx 

 vitiensis, Turn., is very distinct from any of the Psam- 

 mocharidae inhabiting New Caledonia or New Zealand: 

 and Stizus inermis, Handl., is very distinct in the structure 

 of the male antennae from the wide-ranging section of the 

 genus to which it approaches most nearly in other respects. 

 Though doubtless the fauna of the group is very poor in 

 the larger Hymenoptera, there must be many of the more 

 minute species still remaining to be discovered, and it is 

 important that the fauna should be studied before it 

 becomes too much changed by the ravages of cultivation 

 and the competition of imported forms. 



Most of the material used for this paper was collected 

 by Mr. R. Veitch and forwarded to the Imperial Bureau
