 insertion to the top of the head. Thorax transversely striate, 

 anteriorly convex, the mesonotal transverse groove and ridge very 

 distinct ; the metanotum flat above, depressed, the metanotal spines 

 short, erect, acute. Pedicel : the 1st node somewhat squamiform, 

 above transverse, not emarginate, no appendix beneath ; 2nd node 

 transverse, rounded above, laterally cone-shaped, punctured, opaque : 

 abdomen broadly oval, shining, punctured at base, the 2nd and 

 succeeding segments highly polished.

 in front ; antennae stout, the scape extending for about one-third 

 of its length beyond the top of the head. Thorax proportionately 

 broad and very convex anteriorly, the transverse mesonotal groove 

 shallow, the basal portion of the rnetanotum long and flat, the 

 metanotal spines short and acute. Pedicel elongate, from above

 marked, broadening posteriorly and reticulate within ; the front 

 and cheeks coarsely, regularly, longitudinally, the occipital lobes 

 transversely striate. Thorax transversely 'striate, the pronotal
