 furrows not reaching the pronotum but curved off. Mandibles 10- 

 dentate, the tenth tooth very minute, the next 8 comblike. Scape

 wide, 2 a half longer than wide, subequal to 3 and 4. Axillae not 

 advanced. Body coarsely scaly. Propodeum with a black streak 

 like lateral carinae but only a median carina is present. Stigmal
