rest of the body, more or less oval, broad posteriorly ; scape of 

 the antennas short, extending very littJe beyond the top of the 

 head. Thorax : pro- and mesonoturn form one convexity and are 

 emarginate in profile at the meso-metanotal suture as in the I/ ; 

 metanotal spines minute but erect and acute ; nodes of the pedicel 

 proportionately as in the I/ ; abdomen oval. 



c? . Head and thorax fuscous brown, opaque ; mandibles, clypeus, 

 antenna, legs and abdomen yellow, shining. Head subcircular, 

 eyes and ocelli enormous, clypeus convex ; antennae long, the scape 

 short, equal in length to the basal three joints of the flagellum. 

 Thorax massive, oval, the mesonotum broad and somewhat flat. 

 Nodes of the pedicel low, subequal ; abdomen broadly oval. Wings 

 brownish or yellowish white, the nervures and stigma yellow.

 tured ; clypeus with a triangular medial portion depressed, smooth 

 and shining ; antennal carinai short, divergent posteriorly ; no 

 antennal groove ; antennae short, the apex of the scape scarcely 

 reaching half the distance from its insertion to the top of the 

 head. Thorax polished and shining, emarginate at the meso- 

 raetanotal suture, the pro- and mesouotum form one convexity ; 

 metanotal spines short, stout, acute. Pedicel without an append'ix 

 beneath the 1st node, this latter squamiform, its upper margin 

 short, laterally bidentate ; 2nd node transverse, about, twice as 

 broad as the 1st node, its upper margin rounded, produced laterally 

 into cones ; abdomen broadly oval.

 abundant erect reddish hairs ; head, thorax anteriorly and abdomen 

 smooth, polished and shining, the sides of the thorax posteriorly 

 delicately, longitudinally striate. Head posteriorly somewhat 

 transverse and broader than in front ; antennae comparatively 

 stout, the scape extending beyond the top of the head by about 

 one-fourth of its length. Thorax emarginate at the meso- 

 metanotal suture ; metanotum without spines. Anterior node 

 of the pedicel squamiform ; posterior node oval, nearly circular, 

 a little broader posteriorly than in front. 



$ . Resembles the I/ in colour, head smaller proportionately ;
