impressed at apex and elevated into an obtuse tubercle on either side of 

 impression. First gastric segment indistinctly impressed at middle of base. 



Mandibles shining and punctate. Head feebly shining. Cl^-peus strongly 

 and foveolately punctate; front reticulately and rugosely punctate; vertex 

 with two large shallow foveae and cribriform punctures between. Pro- 

 mesothorax coarsely and reticulately costate and subopaque. Epinotum at 

 sides more finely costate; impressed portion foveolately punctate; declivity 

 smooth and shining. Petiole finely rugose. Postpetiole and gaster more 

 shining and uniformly cribrate. Antennae and legs coarsely and densely 

 subopaque. 



Fine, squamiform hairs on head and antennal scapes, coarse ones on legs. 

 Clavate hairs on legs, outer border of scape and one in each of the two foveae 

 on vertex; fine hairs on funiculus, tarsi, and ventral surface of gaster. 



Fuscopiceous; legs, mandibles, antennae, and lamellate borders of epinotum 

 fuscorufous. Hair white. 



Ysabel: Fulakora. 



The single worker of this anomalous species was found beneath a 

 log in the forest. The curious form of the mandibles and the relatively 

 long postpetiole readily distinguish isabcllae from the other Papuasian 

 species. The lack of clavate hairs on the dorsal surface is probably 

 not due to their being rubbed off, for such hairs are abundant on the 

 legs. 



86a. Rhopalothrix procera Emery, subsp. malua, subsp. nov. 



Male. Length 3 mm. 



Head, excluding eyes, much longer than broad; sides posterior to eyes 

 parallel, then oblique to the occipital border which is shall owly concave. 



Vertex broadly and deeply impressed between the 

 ocelli. Frontal cannae strongly elevated. Clypeus 

 convex; concave anteriorly and angulate at sides. 

 Mandibles small and acuminate apically. Antennae 

 slender, scape broad basally, twice as long as first 

 funicular joint; first funicular joint about a third 

 as long as the second; joints two to eleven elongate 

 and cylindrical, becoming shorter toward apex; 

 terminal joint one and a half times as long as 

 penultimate. Eyes shorter than border of cljrpeus, 

 very convex. Mesothorax flattened posteriorly
