but not angulate. Clypcus flattonod at base; convex in front, end divided 

 into two lobes by the strong, triangular medial incision. IMandil>les in length 

 about equal to the distance from their base to the eyes; thickened in front of 

 middle as in chijzeri and armed with two long teeth at apex and a short and 

 curved tooth situated dorsally on the swollen position and not extending to 

 the inner mandibular margin. Antenna! scapes extending more than half the 



distance to occipital corners; funicular joints 

 two and three scarcely longer than broad; 

 fourth joint as long as the three preceding 

 joints. Eyes little convex, composed of about 

 twelve ommatidia. Prothorax flat above; 

 margined at apical third of sides; humeral 

 angles roimded, the disc with irregular carinae. 

 Promesonotal suture marked by a carina. 

 Mesonotum flattened basally, then decUvous 

 to the feeble mesoepinotal impression; mar- 

 gined at sides. Epinotum with subequal base 

 and declivity; base flattened, twice as long as 

 broad and indistinctly margined at sides, de- 

 clivit}' convex, twi?e as long as broad and 

 sharply margined at sides; spines stout, half 

 as long as base of epinotum. Peduncle of 

 petiole longer than the node; node in profile 

 rounded above; from above, longer than broad, with a margin of spongiform 

 appendages behind. Postpetiole transverse, with a narrow border of spongi- 

 form appendages in front, on sides and behind. Legs long and rather stout. 



Mandibles shining and rather closely punctate. Head, thorax, epinotum, 

 and petiole feebly shining, granuloscly punctate and with reticulate carinulae 

 which are most abundant on the head, and lacking on the epinotum and 

 petiole. Postpetiole and gaster more shining and densely punctulate. Legs 

 somewhat shining, densely punctate. Head and body with scattered, erect, 

 and strong pile; first gastric segment costate at base; pile of scapes and legs 

 semierect and very strongly curved. 



Color brownish yellow; mandibles darker.

A number of workers were found beneath leaves on the ground and 

 a colony in rotten wood. The deeply excavated clypeus readily 

 distinguishes antacus from chyzcri Emery which has the anterior 

 border arcuate. The two species are closely related. Sfrnmigcnys 

 loriac Emery from New Guinea has the short mandibular spine before 

 the two terminal ones, situated dorsally, and the cheeks are markedly 

 angulate midway between the eyes and the clypeus. Type. — M. C. Z.
