 dark rufous, smooth. Mandibles black, rufous at the apex ; their base 

 punctured ; their apical tooth long, rounded at the apex ; the hair on 

 their base long and pale fulvous. The head is broader than long, but is 

 largely developed behind the eyes ; the occiput is roundly incised, not 

 transverse or convex. Thorax twice longer than broad; the base and 

 apex almost transverse, with their sides rounded ; the outer edge of 

 the mesonotum is irregular ; the sides of the apex above bear four 

 stout teeth. The top of the median segment has a rounded slope ; it 

 is sparsely punctured, and is keeled down the centre. Pleurse smooth

 The abdomen deep black ; there is a square mark of silvery pubescence 

 on apex of the petiole, in the middle there is a broad band of similar 

 pubescence, broadest in the middle, on the apex of the second segment ; 

 a broader one on the penultimate, and the sides of the pygidium are 

 thickly covered with silvery pubescence ; the last segment is punctured 

 at the base ; the apical half is smooth, shining, and piceous. The 

 keel on the basal ventral segment does not project much, and is 

 rounded at the base and apex ; the second segment is smooth and de- 

 pressed on the basal half, and is there indistinctly keeled in the middle ; 

 the epipygium is closely punctured, and is distinctly bordered laterally.
