^ . Head short, more or less rounded ; mandibles thick, broad- 

 eniug only a little towards the masticatory margin, this latter 

 oblique and armed with 4 acute teeth: clypeus broad, arched in 

 front, the medial portion convex, posteriorly somewhat narrowly 

 rounded between the bases of the antennae ; antennal carinse 

 parallel, wide apart, front area not clearly defined posteriorly ; 

 antennae T-jointed, the scape cylindrical, the joints of the flagellum 

 slender, much longer than broad, no distinct club ; eyes round, 

 somewhat prominent, placed on the sides of the head a little to 

 the front and closer to the top than to the anterior margin of the 

 head. Thorax : the pronotum more or less globose, convex and 

 rounded above, with the anterior lateral angles above and below 

 marked by distinct tubercles or spines ; pro-mesonotal suture 

 obsolete ; mesonotum ending posteriorly in a more or less thick, 

 very distinct transverse carina often subdeutate at the lateral 

 angles; meso-metanotal suture deep, the thorax incised or narrowly 

 emarginate at the suture ; metathorax cubical, compressed, the 

 basal and apical faces subequal, concave from one side to the other, 

 and margined on each side by a carina, the posterior lateral angles 

 of the basal portion armed with an acute oblique spine ; legs long 

 and slender. Pedicel : the nodes conical, subequal, slightly com- 

 pressed, with a distinct but narrow upper surface, the 1st node 

 with a long petiole anteriorly and a very much shorter petiole 

 posteriorly ; abdomen broadly oval, subglobose. 



2 . Head with the mandibles from the front subtriangular, 

 much broader posteriorly than in front, the cheeks convex, the 

 posterior lateral angles rounded ; mandibles, clypeus and antennae 

 as in the ^ ; the eyes larger, placed much higher up just below 

 the upper margin of the ])osterior lateral angles of the head ; 

 ocelli present. Thorax remarkably deep and short, the pronotum 

 vertical, forming no portion of the dorsum ; me?'motuu> very convex 

 and gibbous : scutellum forming a rounded convex boss, overhanging 

 the metanotum, which is entirely vertical and armed laterally with 

 2 strong spines, thick at base and acute. Pedicel as in the ^ , but 

 the nodes larger, broader ; abdomen more massive than in the ^ . 



c? . Head very short, ^ith the eyes very much broader than 

 long, transverse : mandibles narrow, rather short, the apex obtusely 

 rounded, not dentate ; clypeus broad, convex, rounded anteriorly ; 

 antennae 13-jointed, the scape short, not longer than the apical 

 joint of the tlagellum ; eyes oval, enormous, occupying about 

 three-fourtlis of the sides of the head ; ocelli moderatelv prominent. 

 Thorax similar to that in the 2 , but proportionately longer and 

 narrower; the metanolnm unarmed, but with a distinct basal
