border and rounded posterior corners. Eyes large and very convex, 

 at the middle of the sides of the head. Ocelli absent. Clypeus nearly 

 as long as broad, its anterior margin rounded, projecting far beyond 

 the anterior border of the head over the bases of the mandibles, 

 convex but not carinate in the middle. Mandibles long, with the 

 external borders straight at the base and the apical borders with 

 about 9 large teeth alternating with nearly as many smaller ones; 

 the apical teeth longer and more curved. Frontal area and frontal 



groove distinct ; frontal 

 V'.:- • •' . carinse short, subpar- 



allel, slightly diverg- 

 ing behind. Antennae 

 slender, 12-jointed, the 

 scapes extending more 

 than half their length 

 beyond the posterior 

 corners of the head, 

 gradually incrassated 

 towards their tips; 

 funicular joints slen- 

 der, gradually decreas- 

 ing in length distally, 

 joints 1 and 2 subequal and fully 4 times as long as broad, the 

 penultimate joints scarcely twice as long as broad. Thorax long and 

 slender, much like that of Gesomyrmeoc^ but with deeper and longer 

 mesoepinotal constriction and longer pro- and epinotum. Petiole 

 more than twice as long as broad, elongate elliptical from above, in 

 profile bearing in its middle a low rounded node which is not com- 

 pressed anteroposteriorly. Gaster short, elliptical. Legs long, with 

 stout claws on the slightly enlarged terminal tarsal joints and feeble 

 spurs on the middle and hind tibiae. 



Body, legs and scapes finely coriaceous or shagreened and very 

 sparsely and finely punctate. Mandibles and clypeus finely, longi- 

 tudinally striated, the former also with coarse, sparse punctures. 



Hairs very sparse, erect, visible only on the mandibles, on the 

 venter and posterodorsal portion of the gaster. Apparently also the 

 body in life was covered with fine dilute pubescence, but traces of 

 this are distinctly seen only on the head of some of the specimens. 

 Color varying from red to black; the darker specimens often 

 showing signs of considerable decomposition. 



Male. Length about 8 mm; length of fore wing 10 mm.
