backwards to opposite postocular part of orbits; clypeus narrow, 

 intermediate angles short, obtuse, median part emaiginate: pre- 

 ocular sulcus obsolete; eyes convex, rather prominent; postocular 

 part of orbits small but sharply protuberant; two supraorbital 

 punctures on each side; suborbital scrobe narrow and close to 

 gena, an oblique ridge forming its external margin. Labrum 

 short, emarginate, six equally placed setre along its anterior 

 margin. Prothorax convex (3-4 x 3-4 mm.), not declivous to base 

 in middle; sides subparallel, rounded to apex, rounded at pos- 

 terior angles, strongly but Avidely sinuate before base; apex 

 truncate; anterior angles obtuse, not marked; basal lobe wide, 

 defined by a strong transverse impression on each side; border 

 narrow, equal; marginal channel shortly but distinctly recurved 

 at apex; median line strongly impressed, a marginal setigerous 

 puncture on each side of posterior angle.* Elytra ova) (6-5 x 3-5 

 mm.); suture lightly impressed; border thick, narrow; lateral 

 channel narrow, not altogether closed and divided from basal 

 punctate impression by humeral angle of border; base with a 

 light oblique transverse impression on each side, these impres- 

 sions with a double row of punctures (four punctures in lower

 wide apart in middle. Ventral segments convex, 3-6 bipunctate, 

 sixth with a fovea on each side of apex on upturned margin

 it was ticketed as from the Richmond River, N.S.W. 



Very distinct in the genus Carenum, and a puzzling species to 

 place in its true position; the emarginate labrum and clypeus 

 show an affinity to Carenidium frenchi SI., but no species has 

 yet been admitted into the genus Carenidium which has the 



* The usual anterior marginal setigerous puncture is not present in my 

 unique specimen.
