Hab. Singapore. 



A small curved depression at the outerside of the hind

 middle lobe of mesonotum with 2 wide, shallow furrows near 

 the middle a shallow, wider one on the lateral lobe. Scutellum 

 distinctly, but not very strongly, punctured ; its sides and apex 

 margined, the apex more strongly keeled. Post-scutellum 

 depressed, stoutly margined. Base of metanotum with a wide
