" Eyes slightly diverging beneath. Ocelli hardly forming a tri- 

 angle Clypeus Hat, the middle at the apex turned outwardly, 



widely semi-circularly incised and separated from the latei-al pieces 

 by projecting bej^ond them. Head closely rugosely punctured ; 

 the cheeks and lateral margins of the clypeus densely covei-ed 

 with silvery white hair. Mesouotum closely and finely, longitu- 

 dinally, rugosely punctured ; the pleurae coarsely rugose ; trigonal 

 area finely rugose. Abdomen twice the length of the thorax and 

 narrower than it ; the petiole not much broader than long; the 

 punctuation of the segments not very strong ; the pygidial area 

 closely rugose, hardly narrowed at the base ; the apex transverse. 



The third joint of the autenuae longer and thinner than the 



fourth. The cheeks, clypeus, orbits broadly above the base of the
