 extending on to the mesosternum, which it covers entirely, and the 

 apices of the six basal abdominal segments broadly, pale yellow, 

 the base of the third and fourth segments broadly red. Legs bright

 sparsely punctured. Apex of clypeus broadly trilobate, the middle 

 lobe broader and longer than the lateral ; all their apices rounded, 

 lateral fringe white. Pro- and mesonotum punctured, but not 

 closely, the centre of the latter smooth and with a narrow furrow at 

 the base ; the scutellum is more sparsely punctured, the post-

 punctures ; the centre of apical slope hollowed, smooth. Pleurae

 third, and fourth segments depressed at the base. Pygidium slightly 

 narrowed towards the apex, which is slightly rufous ; the punctures
