MANN: wis OF THE FIJI [SLANDS. 421 



The species is \ ery distinct in the structure of the petiole. />. yv/rus- 

 taia Emery, from New Caledonia, nearly related, has similar sculpture 



but the petiole is dilVerent and the antenna! Scapes much shorter. 



Type. M. C. Z, 8,690. 



13, Leptogents (Lobopelta) foveopunctata, sp. nov. 



Worker. Length 8.5 nun. 



Bead distinctly Longer than broad, broadest in Front, posterior border 

 Btraight, sides very Blightly convex. Mandibles rather thick, their blades 

 concave. Clypens broadly triangular, at middle sharply earinate for entire 

 Length. Antenna! scapes surpassing occipital corners by about one fourth 

 their Length. Byes Large, moderately convex, situated at sides of head well 

 in front of middle. Thorax stout. Pronotum broader than long. Meso- 

 epinotum slightly arcuate in profile, broadly rounding into the epinotal 

 declivity. Petiole in profile about as long as high, flattened in front and behind, 

 feebly concave above, highest behind; from above a little longer than broad, 

 moderately narrowed in front. 



Head, thorax, and petiole subopaquc; legs and gaster shining. Mandibles 

 very coarsely punctate. Head, thorax, and petiole foveolately punctate, the 

 punctures more dense on the head, those on the upper surfaces of petiole 

 connected by shallow grooves. Gaster, legs, and antennae finely, though dis- 

 tinctly punctate. 



Pilosity long, fine, and abundant on head, body, and appendages. 



Black; tip of gaster, mandibles, antennal insertions, and the funiculi 

 reddish brown. 



Yanua Levu: Suene. 



Described from two workers. 



Related to letilae but is larger and stouter and different from the 

 other Fijian species in the coarse foveolate sculpture of the thorax and 

 epinotum. 



14. Leptogenys (Lobopelta) humiliata, sp. nov. 



Worker. Length 3.75 mm. 



Head subquadrate, elongate, not appreciably broader in front than behind, 

 sides subparallel, posterior corners rounded, border straight. Mandibles 

 slender, their apical border edentate, concave and separated from basal border 

 by a distinct angle. Clypeus strongly earinate at middle, the anterior pro- 

 jection rather broadly triangular. Antennae thick, their scapes surpassing
