Essential Characters. Abdomen parallel-sided, narrower than thorax; 



second segment elongate. Labruui concealed beneath clypeus. Meso- 

 notuni evenly punctate ; clypeus not apically produced, nor colour 

 metallic. Segments both aciculate and laterally angularly produced ; 

 flagellum of $ centrally dilated and of $ serrate. A single species 

 of this genus only has hitherto been described, and that from Brazil ; 

 but the following fills all the necessary characters and may well find a 

 position therein.

 apices, ocellar region quadrately, antennae except underside of scape,

 and dentiparal areae both before and beyond the costulae, and whole 

 of the hind tibiae and tarsi, black ; stigma fulvous. Face coarsely 

 punctate, centrally elevated and not discreted from the laterally elevated 

 and centrally foveate clypeus ; frons and vertex glabrous, with a slight 

 central tubercle above the scrobes. Antennae gradually attenuate 

 throughout, serrate and slightly shorter than the body. Thorax 

 sparsely and not finely punctate, shining ; areola hexagonal, strong 

 and distinctly longer than broad ; basal sulcus and costulae strong ; 

 dentiparal areae traus-strigose and apophyses wanting. Scutellum 

 strongly convex, glittering and sparsely punctate, with somewhat broad 

 lateral carina almost to its apex. Abdomen parallel- sided and im- 

 maculate, with the three basal segments aciculate ; postpetiole abruptly 

 explanate and laterally subelevated, with no discal carinae; gastrocoeli 

 large and deeply impressed, as broad as the intervening space ; valvulae 

 exserted and not large. Legs normal and not elongate, immaculate
