722 EEVISIONAL NOTES ON AUSTRALIAN CARABID.E,!., 



Clivina NIGRA, n.sp. 



Robust. Clypeus with anterior margin lightly emarginate 

 (median part not divided from wings); elytra with fourth stria 

 outturned and joining fifth at base, submarginal humeral carina 

 short, eighth interstice carinate near apex ; prosternum with 

 episterna finely rugulose-striolate, intercoxal part attenuate 

 anteriorly, transversely sulcate on posterior declivity; anterior 

 tibiae wide, strongly 3-dentate with a small prominence above 

 upper tooth. Black, legs and antennae yellowish-piceous. 



Head wide, rugulose; supra-antennal plates and wings of 

 clypeus wide; clypeus with anterior margin subtruncate (very 

 lightly and widely emarginate), median part in no way divided 

 from wings; supra-antennal plates strongly rounded and bordered 

 laterally; a decided sinuosity at their point of junction with 

 wings of clypeus; eyes very convex and prominent. Prothorax 

 convex, hardly broader than long (1*7 x 1-8 mm.), widest towards 

 base, decidedly narrowed to apex; anterior angles obtuse but 

 marked; anterior margin truncate. Elytra truncate-oval (3-1 x 

 2 mm.), convex, strongly striate; striae deep and coarsely punctate 

 near base, becoming lighter and more finely punctate posteriorly, 

 obsolescent and simple on apical declivity, seventh obsolete at 

 beginning of apical curve; interstices convex near base, depressed 

 posteriorly, eighth very narrow and rather carinate at apex. 

 Length 6-2-6-7, breadth 1-85-2 mm. 



Hab. — N.S.W. : Mulwala (several specimens washed from the 

 margin of a sand bank on the Murray River, December 8th, 1896; 

 Sloane). 



An isolated species readily distinguished from all other Aus- 

 tralian species by its small size in combination with the char- 

 acters noted in the preliminary paragraph of the description 

 above. Evidently most closely allied to C. occulta, SI., a species 

 not now available for reference; but from the description of that 

 species differing by having the anterior margin of the clypeus 

 more evenly emarginate — less truncate in the middle. In appear- 

 ance it resembles C. queenslandica, SI., and C. misella, SI., but
