MANN: ANTS OF THE FIJI ISLANDS. 479 



Color dark brown to lilark, legs yellow-brown. Wings hyaline, veins and 

 stigma pale brown. 



Ovalau: Levuka. Viti Levu: Tai Levu, Saiaro, Nadarivatu, 

 Navai, Waiyanitu, Nausori. Vanua Levu: Labasa. Kadavu: Vuni- 

 sea, Vanua Ava. 



Nests in hollow twigs. 



Among the workers there is a great deal of variation in the contour 

 of the node, which, seen from the front, may be only very slightly 

 convex, moderately excised, or so deeply that extreme examples might 

 be described as bidentate. The angle at the posterior edge of the 

 epinotum varies too, from very sharp to rounded. In some specimens 

 there is a distinct concavity just in front of the spine. 



The worker minor of laminatus always has the epinotum more 

 projecting behind than in crisfatiis and the head of the soldier is more 

 strongly oblique in front. The latter character is so much like that 

 in Colobopsis that I am sure that the species would have been placed 

 in that subgenus had Mayr received a soldier instead of a worker. 



68a. Camponotus (Myrmegonia) laminatus Mayr, var. levuanus, 



var. nov. 



Worker. Length 6.5-7 mm. 



A small series of workers differ from typical laminatus in having the thorax 

 and epinotimi entirely black. The gaster is unusually long and slender. 



Vanua Levu: Wainunu. 



69. Camponotus (Myrmegonia) cristatus Mayr. Fig. 30. 



Sitz. Akad. wiss. Wien, 1866, 53, p. 489, fig. 3, ^ . 



Soldier. Length 9-10 mm. 



Head longer than broad, slightly narrowed in front, sides nearly straight, 

 posterior border very shallowly concave; anterior portion subtruncate, the 

 truncated portion rounding into the front. Cheeks with a broad and shallow 

 impression that extends beyond the lateral borders of clypeus. Clyi^eus sub- 

 quadrate, a little longer than broad, with broadly rounded anterior border, the 

 surface flattened. Mandibles rather elongate, blades with 7-8 blunt teeth. 

 Antennae slender, their scapes slightly surpassing occipital corners; funicular 

 joints gradually decreasing in length toward apex, terminal joint distinctly
