Hab. Borneo, Flores. 



Head short, flat, longitudinally excavated on the upper portion 

 of the face, surface obsoletely wrinkled ; eyes elongate, nearly 

 plane, their inner edge broadly emarginate ; antennae with the five 

 upper joints black, dilated and compressed, forming an ill-defined 

 club. Thorax about twice as broad at the base as long ; sides 

 rounded and converging from base to apex, hinder angles pro- 

 duced slightly backwards, acute ; basal margin distinctly sinuate 

 and concave on either side, produced obliquely backwards as it 

 approaches the medial lobe; this latter broadly truncate, its border 

 broadly emarginate to receive the base of the scutellum ; upper 

 surface very convex, more especially in front, whole surface 

 covered (but not very closely) with shallow punctures, visible 

 only under a lens ; the extreme basal margin, together with the 

 base of the scutellum, narrowly edged with black. Scutellum 

 moderate in size, subcordate, its basal margin being deeply 

 notched. Elytra convex, gradually narrowed from their base 

 towards their apex, sides very slightly lobed at the base ; surface 

 plane, not thickened near the scutellum, closely covered with very 

 minute impressed strigae, visible only under a lens ; on each 

 elytron are eleven rows of regulai'ly placed fine punctures, which 

 become much less distinct and nearly obsolete towards the apex. 

 Pygidium closely punctured.
