Hab. Matang. August. 



Face minutely punctured, the centre from near the top 

 bordered by furrows, which end in foveas above the clypeus 

 which is minutely punctured. Labrum large, broadly rounded. 

 Front depressed in the middle, the depression bordered by 

 furrows, which are roundly curved above, converging below ; 

 the lateral keels reach to the ocelli. Parapsidal furrows wide, 

 bearing stout keels, forming deep foveas ; at the apex they 

 converge, but do not unite. Apex of scutellum with a trans- 

 verse stout keel. Metanotum depressed at the base, the sides 

 more deeply than the centre ; at the apex of the depression is 

 an area, longer than wide, which becomes gradually wider to the 

 apex, which is transverse and bears a stout transverse keel ; 

 following this is a depression about 3 times wider than long, 

 rounded, but not much narrowed, at the apex and bordered by 

 larger, longer depressions, wide at the base, becoming narrowed 

 gradually to a point at the apex and touching the curved keel 

 surrounding the apex ; outside it are 2 large? wider depression, 

 the outer being the larger. Pleural and sternal depressions 

 wide and bearing stout keels all over.
