 pubescence ; the hair on the upper part of the outer orbits is black,

 and is clearly separated ; below it is fringed with rufous hair. The 

 mandibles are widely grooved above, narrowly below ; the tooth is 

 long and becomes gradually narrowed towards the apex ; there is 

 no subapical or upper tooth ; the space above the lower tooth is 

 roundly curved. The entire upper part of the thorax is thickly
