Worker. Length 3 lines. Black, with the abdomen smooth and shi- 

 ning ; the head and thorax subopake, and thinly covered with cine- 

 reons pile; mandibles shining black; the palpi pale testaceous. 

 Thorax armed in front with two stout acute spines, the metathorax 

 with two, more slender and longer diverging spines ; the peduncle has 

 two long spines which curve round the base of the abdomen ; the 

 tibiae ferruginous, but more or less obscure at their base. 



Hob. Makassar. 



Gen. PsEUDOMTBMA, Guer. 



1. Pseudomyrma laeviceps. Smith, Proc. Linn. Soc, 1859, iii. p. 145. 

 Hab. Celebes ; Aru. 



The specimens from Makassar are smaller than those from Aru, but I 

 can detect no specific difference. 



Pam. PONEEID^. 

 Gen. Odontomachfs, Zatr. 



I. Odontomachus simillimus, Smith, Cat. Hym. Ins. Form. p. 80, pi. 5. 

 figs. 8, 9. 



This species closely resembles O. hcematodes, but may be known by the 

 following differences : the mandibles are distinctly serrated throughout 

 the entire length on the inner margin ; the head narrower and the 

 antennae shorter in the worker; in the female the neuration of the 

 wings is different. 



Hab. Celebes (Makassar) ; Fidjee Islands ; Ceylon. 



Gen. PoNEBA, Latr. 



1. Ponera geometrica, Smith, Proc. Linn. Soc. ii. p. 67. 

 Hab. Celebes (Makassar). Singapore. 



2. Ponera Iseviceps, Smith, Proc. Linn. Soc. ii. p. 69. 

 Hab. Celebes (Makassar) ; Borneo (Sarawak). 



The specimen from Celebes has a few indistinct traces of sculpture on 

 the crown of the head and prothorax, but so closely agrees in all other 

 respects, that I cannot see a good specific difference. 



,3. Ponera truncata. P. nigra; antennis, mandibulis, pedibus, 

 abdominisque apice ferrugineis. 



Female. Length 20 lines. Black ; the clypeus, antennse, mandibles, 

 legs, the apex of the metathorax and of the abdomen ferruginous ; 

 the eyes placed forward at the sides of the head, near the base of the 

 mandibles ; the head, thorax, and abdomen thinly covered with a fine, 

 short, downy pile, which renders the body sub-opake ; the truncated 

 portion of the metathorax very smooth and shining ; the mesothorax 

 with an obscure rufous tinge. The a])ical margins of the two basal
