with broad, minutely denticulate apical borders. Clypeus large. Frontal 

 carinas subparallel, rather long, slightly curved, most prominent in front. 

 Antennae rather stout, 12-jointed, the funiculi enlarged towards the tip, 

 consisting of joints of subequal length, without a differentiated club. 

 Thorax narrower than the head, but little narrower behind than in 

 front, with sharply defined promesonotal and mesoepinotal sutures, 

 moderately constricted at the latter. Metathoracic spiracles large, pro- 

 jecting, approximated dorsally in the mesoepinotal constriction. Epino- 

 tum nearly as large as the remainder of the thorax, bidentate. Petiole 

 much longer than broad, slender and pedunculate anteriorly, surmount- 

 ed behind the middle by a rather high, rounded node, behind which 

 it is abruptly constricted. Gaster large, oval, not over -hanging the 

 petiole anteriorly. Sting very long and well -developed. Legs rather 

 slender, all the tibiae with feebly but distinctly pectinated spurs. 

 Claws simple. 



Female (dealated). Scarcely larger than the worker and much like 

 it except in the more robust thorax, larger eyes and the presence of ocelli. 



This genus is very close to the genus Aneuretus represented by 

 a single species, A. simoni Emery, living in Ceylon and known only 

 from the worker phase, but the head is less cordate, the eyes are much 

 larger, the frontal carinae are longer and much more elevated and the 

 antennae, legs and peduncle of the petiole are much less slender. 



Protaneuretus siiccineus sp. nov. 



Worker (Fig. 31a — c). Length 5,5 — 7 mm. 



Clypeus and mandibles feebly convex, the former apparently with 

 broadly rounded, entire anterior border. Antennal scapes reaching a 

 little more than halfway between the posterior orbits and the posterior 

 corners of the head; joints 1—5 of the funiculi a little longer than 

 broad; joints 6 — 10 as broad as long, terminal joint as long as the 

 two preceding together. Pronotum about as long as broad ; mesonotum 

 small, elliptical, a little longer than broad. Epinotum with subequal 

 base and declivity, the former convex and rounded, the latter flat and 

 sloping. Teeth of the epinotum directed upward, not longer than broad 

 at their bases, much further apart than long. Node of petiole rising 

 rather abruptly from the peduncle, with flattened anterior surface, 

 rounded superior and convex posterior surfaces; seen from above it is 

 transverse and slightly compressed anteroposteriorly. 



Surface of body shining, smooth and sparsely punctate; meso- 

 epinotal constriction, meso- and metapleurae longitudinally, basal sur- 

 face of epinotum transversely rugose.
