small, rouiul, rather fiat. Thorax narrow ; proiiotiim rouiuled 

 anteriorly, pro-mesoiiotal suture tolerably distuict, inesouotum 

 verv convex ; meso-iuelaiiotal suture deeply impressed ; the basal 

 portion ot the metanotum ])assing into the apical portion by a 

 regular curve, and longitudinally channeled down the middle, 

 with the sides projecting posteriorly and triangularly at the 

 posterior lateral angles ; legs somewhat slender and long. Pedicel : 

 the 1st node squamiform, transverse, shortly petiolate anteriorly, 

 the petiole and front of node viewed iu protile forming a regular 

 curve ; 2nd node from above transversely oval, broader than long ; 

 abdomen oval anteriorlv, slightly truncate. 



g, llesembles the If., but is, of course, much smaller, the 

 mandibles are 4-dentate ; the apical tooth long and acute, the pro- 

 mesonotal suture obsolete, thorax seen in protile einargiuate at the 

 meso-metanotal suture. 



5 . Head as in the If , but the eyes larger and ocelli present, 

 the medial groove more feebly impressed, the antennae 11- 

 jointed. Thorax a little broader than the head, the mesonotum 

 long, gibbous in front, convex ; metanotum short, unarmed, the 

 basal portion oblique, the apical portion vertical. Pedicel as in 

 the If., but shorter and more stoutly built, the 2nd node not so 

 thick above as in the If , with the short petiole connecting it 

 posteriorly with the abdomen thicker ; abdomen more massive, 

 an elongate oval. Eoi'e wing with one cubital and one discoidal 

 cell. 



(5" . Eesembles the $ , but the head is smaller, the thorax 

 proportionately very much more niassive and deeper. Head 

 short, very much broader in front than posteriorly ; mandibles 

 narrow, with three acute teeth, clypeus arched ; eyes and ocelli 

 lar^e and very prominent ; antenme 12-jointed, the scape short, 

 about as long as the 2nd joint of the Hagellum. Thorax : the 

 mesonotum extraordinarily convex and gibbous in front, entirely 

 suppressing the pronotum, which is greatly narrowed in front ; 

 scutellum very convex and raised higher than the mesonotum ; 

 metanotum unarmed, roundly sloped posteriorly. Pedicel much 

 as in the § ; abdomen shorter, broadly oval. Wings as in the $ , 

 but the cubital cell ii^ the fore wing broader and shorter.
