 under side covered with pale fulvous hair ; the flagellum 

 thickly with a microscopic pile. Head black, with a 

 distinct plumbeous hue ; the face, the inner orbits to 

 opposite the lower part of the ocelli, the outer orbits on 

 their lower two-thirds and the palpi, yellow. The front 

 and vertex smooth and impunctate, almost bare ; there is 

 a furrow between the ocelli ; behind the eyes is an obscure 

 rufous patch. Face shining, smooth, sparsely covered

 discoloured), smooth ; the apical two-thirds depressed ; its 

 apex depressed, rounded at the sides. Mandibles smooth,

 of the mesonotum, the median segment above, and the 

 apical half of the metapleurse, black ; the greater part of

 punctured; the sides of the raised basal lobe irregularly 

 striated; the depressed apical central part black, and
