MANN: ANTS OF THE FIJI ISLANDS. 427 



19. Odoxtomachus angulatus Mayr. Fig. 11. 



Sitz. Akad. wiss. Wien, 1SG6, 53, p. 500, pi. 1, fig. 10, § . 



Female (deiilated). Length 13 mm. 



Very similar to the worker, but with the usual sexual differences. The 

 gaster is enlarged to an extent unusual in the genus. The ocelli are far apart 

 as in the female of ha^tatiis, the two lateral ones small and the median large. 



Viti Levu: Xadarivatu. » 



This species was described by Mayr from workers collected on 

 Ovalau. I searched for it unsuccessfully on that island as well as in 

 numerous other localities, finally coming across it in the canyons that 

 cut into the dry hillsides on the north slope of the mountains at 

 Nadarivatu. A stream runs through each of these canyons and angii- 

 lafus was always near these, sometimes foraging in situations con- 

 stantly wet by spray from the waterfalls. It forages during the day 

 time. 



The nest is in the ground, sometimes beneath a stone, but more 

 often about the roots of trees. 



20. Odontomachus haematoda (Linne). 



Formica haematoda Linne, Sj'st. nat. ed. 10, IToS, 1. p. 582, 9 . 



Distributed commonly everywhere throughout the islands, even to 

 One i Lau, the end of the Lau Archipelago. 



21. Pheidole oxifera, sp. nov. Fig. 12. 

 Soldier. Length 2.75 mm. 



'&' 



Head a little longer than broad, sides nearh' straight, occipital angles 

 broadly rounded, border rather broadly and not deeply concave; vertex not 

 transversely impressed but with a narrow longitudinal sinus extended on the 

 front almost to the frontal area. IMandibles elongate, obtusely bidentate 

 apically. Ch-|:)eus very shallowly concave at middle of anterior border. 

 Frontal carinae little divergent, extending beyond tips of scapes and bordering 

 broad, shallow scrobes. Antennal scapes extending nearly two thirds the 

 distance to occipital corners; funicular joints 2-8 little broader than long; 

 club nearh- as long as the remainder of funiculus, with the terminal joint as
